Description

  The present invention relates to material management in a component mounting process at a circuit board manufacturing site, and relates to a component outage notice method for notifying a component out of an electronic component mounted on a circuit board, and for causing a computer to execute the component out notice method. The present invention relates to a program for running out of parts, a device for running out of parts, and a component mounting system including the device for running out of parts.

In recent years, in each production process of the manufacturing industry, the necessity of producing with high-efficiency operation for 24 hours is further increased. In particular, in the mounting process, which is a source process, in order to reduce equipment downtime required for parts replenishment due to parts being cut off in the parts supply device, a constant monitoring system is drawn by the operator. Here, as shown in FIG. 12, the component supply apparatus supplies the electronic component 2 by feeding out the tape 3 from the reel 4 around which the tape 3 in which the electronic components 2 are stored in a row at regular intervals is wound. A so-called parts cassette is provided, and a plurality of component supply devices 1 are arranged in parallel in the component mounter 10 as shown in FIG. In such a component supply apparatus 1, when the remaining tape amount is low, that is, when the component nears running out, the operator connects the end of the new tape to the end of the remaining tape, That is, parts replenishment work is performed. By such a component replenishment operation, the component mounter 10 can be continuously operated without causing the component to run out. On the other hand, when the parts are supplied to the end of the tape, the mounting operation must be stopped, and the reel 4 is replaced as a part replacement.
Therefore, in order to continuously operate the component mounter 10 and improve the production efficiency of the circuit board, it is important to predict the component shortage in each component supply device 1 and to call attention to the operator.

  Hereinafter, a conventional method for notifying parts shortage will be described with reference to FIG. In FIG. 14, the conventional component shortage notice device 20 is roughly provided with a central processing unit 21, a storage device 22, a first input device 23, a display device 24, and a second input device 29. In the storage device 22, the component input information 26, which is input from the first input device 23 and registered for each component supply device and the number of electronic components input to the component supply device 1, is stored in the circuit substrate as a product. Component configuration master information 27 in which the type and quantity of electronic components to be mounted are registered, and consumption information of electronic components that are input from the second input device 29 and consumed in producing one circuit board in the component mounting machine 10. Is stored. The central processing unit 21 is provided with the above-described part-out notice calculation means 25 to which the part input information 26, the part configuration master information 27, and the part consumption information 28 are supplied. As will be described below, the time at which a component shortage occurs is calculated for each component supply device 1. The display device 24 visually displays the component supply device 1 in which component failure occurs based on the calculation result calculated by the component failure notice calculation means 25 and the component mounter 10 including the component supply device 1. To do.

The operation of the conventional component short notice device 20 configured as described above will be described below. First, the initial input number of material components to the component mounter 10 is registered in the storage device 22 as the component input information 26 from the first input device 23. The part input information 26 includes part input date and time, product part number information necessary for the part outage notice calculation, input destination equipment, Z-axis number, input quantity, and the like. Here, the Z-axis number is a number representing the arrangement order of the component supply devices such as the part feeder provided in the component mounter, and is uniquely assigned to each component supply device.
The component-out notice calculation means 25 refers to the input date / time and the number of inputs included in the component input information 26, and includes information on the amount of consumption of electronic components included in the production of one circuit board included in the component consumption information 28. And the component type mounted on the circuit board included in the component configuration master information 27 and the number of components are multiplied to determine a notice time for occurrence of component shortage for each component supply device 1.
Further, the component-out notice calculation unit 25 ignores the component-mounter-by-unit based on the obtained component-out notice by component mounter and by Z-axis number, and simply performs the above Z-axis only at the part-out notice time. By rearranging the numbers, that is, the component supply devices, it is possible to determine from which component supply device 1 in which component mounter 10 the component breakage occurs in order.

  However, in the conventional component short notice device 20, after calculating the component short notice time as described above, only the result is displayed on the display device 24. After the calculation, the production of the component mounter 10 is performed. Recalculation in consideration of the consumption and consumption time of each component based on the delay and advance of the machine and updating the component outage notice time means that the communication speed of the communication means between the component mounter 10 and the component outage notice device 20 is increased. It was late and not done.

  Conventionally, as described above, it is only determined from which component supply device the component out occurs in order based on only the component out advance notice time. However, in practice, the time required for component replenishment varies with each component supply device depending on the component type, and therefore it is necessary to consider the length of the component replenishment work time in order to give notice of component shortage. Furthermore, since the number of components supplied from each component supply device is different in manufacturing one circuit board, it is necessary to consider the timing for connecting the tapes. In other words, a component supply device having a large number of components to be supplied to a single circuit board has a high component supply speed, so it is necessary to start component replenishment work earlier, but the tape for supplying components as described above. 3 is wound around the reel 4, and if the component replenishment operation starts too early, the end of the tape is still wound around the reel 4, and the replenishment operation cannot be performed. On the other hand, if the start of the component replenishment operation is too late, the component replenishment operation cannot be completed before the occurrence of component outage. Thus, it is necessary to consider the component replenishment timing according to the number of components supplied.

  In the past, because the above-mentioned update operation of the part shortage notice time, the length of the part replenishment work time, and the part replenishment notice were performed without considering the part replenishment timing, the part shortage notice time calculated first was used. When the part is actually replenished, there is a discrepancy in the time when the part runs out. Is still wound around the reel 4 and the parts cannot be replenished. On the other hand, even if the parts replenishment order is lower, the number of users for one circuit board is larger, so the parts replenishment order is higher than the higher order. However, there have been cases where the remaining number of parts that require parts replenishment work has been reached first, resulting in a situation where equipment is stopped. Therefore, the conventional part cutting notice time is only a rough guide. Moreover, if it is a skilled worker, it is also possible to perform parts replenishment work based on experience and the like with reference to the above-mentioned prior notice time of parts shortage, so as not to cause equipment stoppage. For example, when a 24-hour production is performed, a skilled worker does not always work, and the equipment may be stopped due to a lack of parts. As described above, the conventional parts short notice device and method are insufficient and cannot always be said to contribute to the improvement of production efficiency.

  The present invention has been made in order to solve such a problem, and it is possible to improve the production efficiency compared to the prior art without causing a component failure, and to further improve the work efficiency of the operator. It is an object to provide a notice method, a program for causing a computer to execute the part-out notice method, a part-out notice apparatus for executing the part-out notice method, and a component mounting system including the part-out notice apparatus. .

  Further, after determining the part replenishment order based on the extracted part run-out time, the provisional part remaining number in each part supply device at the time of part replenishment when the parts are replenished according to the part replenishment order. A certain part provisional remaining number may be obtained based on the part replenishment work time included in the part replenishment condition information.

  In addition, after obtaining the component temporary remaining number, the component replenishment order may be updated in consideration of workability related to the component replenishment operation.

  In consideration of the workability, the maximum number of remaining parts which is included in the part replenishment condition information and is set for each of the part supply devices and which can be used for the part replenishment work, and the part provisional The comparison with the remaining number may be performed for each of the component supply devices.

  In addition, as a result of the comparison between the maximum remaining component number and the temporary component remaining number, the component supply device in which the temporary component remaining number is equal to or larger than the maximum remaining component number is excluded from the comparison operation target with the maximum remaining component number. You may make it do.

  In addition, after the above exclusion, the parts replenishment order may be updated, and the updated part temporary remaining number updated in accordance with the renewal parts replenishment order may be obtained.

  Further, when the renewal component temporary remaining number is less than the maximum remaining component number, it is further included in the component replenishment condition information and is set for each component supply device and is the minimum required component replenishment operation. The minimum number of remaining parts, which is a number, may be compared with the updated part temporary remaining number for each of the component supply apparatuses.

  Further, as a result of the comparison between the minimum component remaining number and the updated component temporary remaining number, when there is a component replacement required component supply device in which the updated component temporary remaining number is less than the minimum component remaining number, the renewal component replenishment is performed. From among the parts supply devices whose parts replenishment order is earlier than the parts replacement required component supply device within the range of the order, the maximum component supply device with the maximum component outage time is excluded from the comparison operation target with the maximum remaining component count. You may make it do.

  Further, until the updated part temporary remaining number becomes equal to or greater than the minimum part remaining number and the part replacement required part supply device does not exist, the maximum part remaining number and the updated part temporary remaining number are compared, and the minimum part The comparison between the remaining number and the updated part temporary remaining number may be repeated.

  In addition, when there is a component supply device in which the component expiration time is equal to or shorter than the second set time, the installation operation stop may be warned to the equipment having the component supply device.

  The sampling time may be variable according to the mounting operation state.

The method further includes a procedure of extracting a part cut-off time exceeding a certain second set time.
It is characterized by that.

Furthermore, the component shortage notification device according to the third aspect of the present invention is a component shortage notification device for notifying the component shortage in each component supply device that supplies electronic components mounted on a circuit board,
An input device that samples component consumption information that changes during component mounting in each of the component supply devices from a component mounting device that includes the component supply device every sampling time;
Component configuration master information, which is information regarding the number and type of electronic components mounted on one circuit board, component input number information which is information on the number of electronic components input to each of the component supply devices, The component consumption information is supplied, the component outage time until the component outage occurs is obtained for each of the component supply devices based on the information, and the electronic component replenishment operation information is provided for each component supply device. The part replenishment condition information set in is provided, and a notice determining unit for determining a part supply device in which part outage occurs in consideration of the part replenishment condition information based on the obtained part outage time ,
The advance notice determining unit further determines the part outage time from the obtained part outage time within a first set time, which is a time for the part outage recommendation, after determining the part outage time and before determining the part replenishment order. A part outage time exceeding a second set time which is a part outage recommendation time is extracted, and the part replenishment order is determined for the part supply apparatus having the extracted part outage time .

Furthermore, a component mounting system according to a fourth aspect of the present invention includes a component mounting apparatus that includes each component supply device that supplies an electronic component mounted on a circuit board and mounts the electronic component on the circuit board.
The component outage notice device according to the third aspect, which performs the advance notice of component outage in the component supply device based on the component consumption information connected to the component mounting device and supplied from the component mounting device,
It is provided with.

According to the part-out notice method of the first aspect of the present invention, the part-out notice program of the second aspect, the part-out notice apparatus of the third aspect, and the component mounting system of the fourth aspect, the following effects can be obtained. That is, an input device is provided, and after the start of component mounting, component consumption information in each component supply device that changes from time to time during component mounting is obtained, and the component dead time is obtained for each component supply device based on the component consumption information. . Therefore, as compared with the conventional case where the component outage time is obtained based on the component consumption information acquired only once, the component outage time is obtained by reflecting the component supply state of each component supply device during component mounting. Therefore, it is possible to obtain the part run-out time with higher accuracy than in the past. Therefore, it is possible to reduce the occurrence of component breakage compared to the conventional case, and thus to improve the production efficiency. Thus, for example, the worker is released from the regular monitoring work of equipment and engaged in incidental work. It is possible to reduce the work burden on the worker and improve the work efficiency.
In addition, since various electronic components are supplied from each component supply device, the time required for the component replenishment work when the component is almost out varies. In the conventional part run-out notice, the part replenishment work time is not considered at all. On the other hand, in each of the above aspects of the present invention, the component replenishment condition information is set for each component supply device, and when the component outage notice order is obtained, the order of component replenishment in consideration of the component replenishment condition information is determined. In accordance with the parts replenishment order, the parts are run out. Therefore, since the part replenishment order can be determined with higher accuracy than in the prior art, it is possible to reduce the occurrence of out of parts as compared with the prior art, thereby improving the production efficiency and the work efficiency of the operator. it can.

  In addition, by providing the first set time, which is the time for recommending component shortage, it is possible to narrow down the target component supply devices that require the component shortage notice. Furthermore, when there is a parts supply device that cannot be dealt with by parts replenishment work and the number of parts remaining that require parts replacement work, providing a second set time to warn of equipment stoppage requires the notice of parts shortage. It is possible to further narrow down the component supply devices to be processed. Therefore, by executing the component outage notice for the component supply device that exceeds the second set time and has the component outage time within the first set time, the component outage notice can be executed at higher speed.

  Further, the parts replenishment order is obtained in consideration of workability related to the above-described parts replenishment work, which has not been considered at all in the past. That is, when parts are replenished to the parts supply apparatus, there is an appropriate period for parts replenishment. That is, when there is an excessively large number of remaining parts, or when the remaining number of parts is so small that parts cannot be replenished already, the workability of parts replenishment is significantly reduced, and a great deal of time is spent on parts replenishment and parts replacement. In the meantime, there is a possibility that other parts supply devices will run out of parts and cause the equipment to stop. Therefore, it is very important to give a notice of running out of parts in consideration of workability in parts replenishment work. Therefore, by further considering the above workability, it is possible to determine the order of component replenishment with higher accuracy than in the past, and to reduce the occurrence of component breakage as compared to the conventional case. Therefore, it is possible to improve production efficiency and work efficiency for the worker.

  In addition, since each component supply device continues to supply components while performing the component replenishment work according to the determined component replenishment order, the remaining number of parts in each component supply device once the component replenishment order is obtained. Is changing. Therefore, also in consideration of the above workability, the provisional remaining number of parts is obtained for each component supply device when it is assumed that the component replenishment work has been performed according to the obtained component replenishment order. Since the part replenishment order can be determined with higher accuracy than in the past by determining the provisional remaining number of parts in this way, it is possible to reduce the occurrence of component outbreaks compared to the conventional case, thereby improving production efficiency and working. It is possible to improve the working efficiency of the person.

As one of the above workability considerations, the case where the number of remaining parts is excessive is considered. In other words, the maximum number of remaining parts, which is the maximum number of remaining parts that is set for each part supply apparatus and can perform the parts replenishment operation, is compared with the above-mentioned temporary remaining number of parts. As a result of the comparison, if the part remaining balance is greater than or equal to the maximum remaining part number, that is, if the remaining part number is excessively large, it is not necessary to replenish the part at this point. The component supply device having the number is excluded from the comparison operation targets. As a result, it is possible to reduce the number of populations that require the part-out notice, and it is possible to execute the part-out notice at a higher speed.
Further, in the population of parameters reduced as described above, the part replenishment order is obtained again, the part replenishment order is updated, and the updated part temporary remaining number updated according to the updated part replenishment order is obtained. By updating the parts replenishment order in this way, it is possible to determine the part replenishment order with higher accuracy than in the past, so that it is possible to reduce the occurrence of part shortage compared to the conventional case, thus improving production efficiency and working It is possible to improve the working efficiency of the person.

  Furthermore, in consideration of the above-mentioned maximum number of remaining parts, a case where the remaining number of parts is so small that the parts cannot be replaced is considered as one of the workability considerations. That is, a comparison is made between the minimum number of remaining parts that is set for each part supply device and is the minimum number of remaining parts required for the parts replenishment operation, and the updated number of remaining temporary parts. As a result of the comparison, when the updated part tentative remaining number is less than the minimum remaining part number, that is, when there is a part replacement required part supply device that requires urgent part replenishment, the updated part replenishment order range is used. From among the component supply devices whose component replenishment order is earlier than that of the component replacement-required component supply device, the maximum component supply device having the maximum component outage time is excluded from the comparison operation target with the maximum component remaining number. As a result, it is possible to reduce the number of populations that require the part-out notice, and it is possible to execute the part-out notice at a higher speed.

  In addition, for the new parameter group excluding the maximum component supply device as described above, again the comparison between the maximum component remaining number and the updated component temporary remaining number and the minimum component remaining number and the updated component temporary remaining value are performed. The comparison with the number is repeated until the above-described component replacement required component supply device is not present. By further updating the parts replenishment order in this way, it is possible to determine the part replenishment order with higher accuracy than in the past, so that it is possible to reduce the occurrence of part shortage compared to the conventional case, thus improving production efficiency, In addition, it is possible to improve the work efficiency of the worker.

  In addition, when there is a parts supply device in which the part run-out time is equal to or shorter than the second set time, that is, when the remaining part number is less than the minimum remaining part number and the equipment is about to stop, an equipment stop warning is issued. As a result, it is possible to prompt the worker to refill or replace parts as soon as possible. Therefore, it is possible to reduce the occurrence of component breakage compared to the conventional case, and thus it is possible to improve the production efficiency and the work efficiency of the operator.

  In addition, by making the sampling time variable, it is possible to adjust the time for notifying parts in accordance with the mounting operation status of the component mounting apparatus, and therefore, it is possible to reduce the occurrence of parts shortage compared to the conventional case. Therefore, it is possible to improve the production efficiency and the work efficiency of the worker.

After the components are held, the component holding head 202 is positioned above the component mounting position on the circuit board 5 by the X, Y-robot 203, and the component holding member 202a is lowered again to hold the electronic component 2 held above. Mount to the mounting position. By repeating such an operation, a specified type of electronic components 2 are mounted on a single circuit board 5 in a specified quantity, thereby completing one circuit board. The circuit board 5 after component mounting is carried out by the board transfer device 201.
By executing the mounting operation in this way, the number of electronic components 2 is reduced from each component supply device 1 by the number required to complete one circuit board 5.

  The component mounting system 400 is configured by the component shortage notice device 101, the component mounting device 200, and the information collection device 300 described above. When there are a plurality of component mounting apparatuses 200, a plurality of component supply apparatuses 200-1 to 200-n are connected to the information collecting apparatus 300 as described above.

  With the configuration described above, the operation of the component mounting system 400, particularly the operation of the component shortage notification device 101, that is, the component shortage notification method will be described below with reference to the drawings. Note that, as described above, the part-out notice method is executed under the control of the control device 110 according to the notice program 125 a stored in the notice program storage unit 125. In the following description, it is assumed that the component mounting system 400 includes a plurality of component mounting apparatuses 200, and each component mounting apparatus 200 includes a plurality of component supply apparatuses 1.

  Before starting the component mounting operation, the component input information 121a in each component supply device 1 is supplied from the first input device 23 to the component input information storage unit 121. As described above, the part input information 121a is information such as the part input date and time, the product part number information necessary for determining the part outage notice, the input destination equipment, the Z-axis No., and the input quantity. The component configuration master information storage unit 122 stores component configuration master information 122a in advance. The component configuration master information 122a is information relating to the type and number of electronic components mounted on one circuit board as described above, and the time required to produce one circuit board as described above. Production tact information is included. Furthermore, the component replenishment condition information storage unit 123 stores in advance the component replenishment work time C included in the component replenishment condition information 123a. The component replenishment operation time C is the time required for performing the component replenishment operation to the component supply device as described above, and is information set for each component supply device.

  During component mounting after the start of component mounting, the information collection device 300, for example, from about 0.5 to 1 minute from each component mounting device 200, the number of components consumed for each component supply device 1 included in each component mounting device 200 And the difference in consumption of parts corresponding to the difference between the number of parts consumed at the previous collection and the number of parts consumed at the current collection is obtained. The component consumption difference number corresponds to the component consumption information 124a. The third input device 130 accesses the information collecting device 300 every sampling time, for example, about every 5 minutes, and acquires the number of component consumption differences, that is, the component consumption information 124a for each component supply device 1. As described above, when the information collection timing of the information collection device 300 is different from the sampling time by the third input device 130, the component consumption information 124a acquired by the third input device 130 is the difference that the information collection device 300 has. The number is integrated for each component supply device 1. Also, the acquired component consumption difference number, that is, the component consumption information 124 a is supplied from the third input device 130 to the component consumption information storage unit 124 and stored therein.

  In step (shown by S in FIG. 3) 101, functionally described, the notice determining unit 111 of the control device 110 stores the component consumption information 124 a from the component consumption information storage unit 124 and the component configuration master information. The component configuration master information 122a is read from the unit 122. In the next step 102, the remaining number determination unit 113b of the notice determination unit 111 reads the component input information 121a from the component input information storage unit 121, and then calculates the component consumption information 124a from the number of components input in the component input information 121a. By subtracting, the component remaining number Zv at the present time in the component supply apparatus 1 is obtained. Since the component consumption information 124a and the component input information 121a in all the component supply devices 1 in each component mounting apparatus 200 are acquired as described above, the remaining component number Zv is the total component supply in each component mounting apparatus 200. It is obtained for each device 1. In the following description, unless otherwise specified, each component mounting apparatus 200 can obtain each data described in the step for each component supply apparatus 1 targeted in the step.

  In the next step 103, after step 102, it is determined for every component supply apparatus 1 whether or not a component has been replenished or replaced. If there is no replenishment or replacement, the process proceeds to the next step 105. On the other hand, if the above replenishment or replacement is performed, the remaining part number Zv is replaced with the number of parts input in step 104, and the process proceeds to step 105. As described above, in the present embodiment, as the component supply device 1, a so-called parts feeder in which the tape 3 containing the electronic component 2 is wound around the reel 4 is taken as an example. Therefore, in the present embodiment, the above-described component replenishment refers to the operation of connecting the end of the new tape 3 to the end of the tape 3, and the above-mentioned component replacement refers to the removal of the old reel 4 that has been used and the new reel. 4 refers to performing the operation of replacing.

In step 105, the component time-out determination unit 113a obtains the component time-out time Zt, which is the remaining time until the next component-out occurs, for each component supply device 1 of each component mounting apparatus 200. Specifically, the component expiration time determination unit 113a divides the remaining component number Zv obtained in step 102 by the number of electronic components mounted on one circuit board in the component configuration master information 122a. Further, by multiplying the production tact information in the component configuration master information 122a, the component run-out time Zt is obtained.
In step 106, the notice determination unit 111 refers to the component expiration time Zt for each component supply device 1 obtained in step 105, and the component mounting apparatus 200 increases from the shorter component expiration time Zt to the longer component expiration time Zt. Further, in order, the arrangement on the data is performed in the order of the component supply apparatus 1. A conceptual diagram of the arrangement state is shown in FIG. In FIG. 7, assuming that there are three component mounting apparatuses 200, A, B, and C represent the respective component mounting apparatuses 200, and the component mounting apparatus A and the component mounting are within the component run-out time Zt of 0 to 1 minute. FIG. 2 illustrates an assumption that a component supply device 1 that requires component replenishment occurs in the device B and the component mounting device C, and that a component supply device 1 that requires component replenishment occurs in the component mounting device B for 1 to 2 minutes. Yes. Further, the component mounting apparatus 200 including the component supply apparatus 1 having a shorter component cut-off time Zt is illustrated in the lower stage. That is, when the component out-of-time Zt is between 0 and 1 minute, the component mounting apparatus A has the component supply apparatus 1 that needs to be replenished earliest, and the component out-of-time Zt is in the order of the component mounting apparatus B and the component mounting apparatus C. become longer. For example, the component mounting device A has a component supply device 1 with a component outage time Zt of 20 seconds, and the component mounting device B has a component supply device 1 with a component outage time Zt of 40 seconds and 80 seconds. The mounting apparatus C includes the component supply device 1 having a component cut time Zt of 55 seconds.
In the present embodiment, the data that the component run-out time Zt is less than or equal to a second set time X to be described later is defined to be arranged in the order of the component mounting device 200 and the component supply device 1. In the part-out notice information sent from the control device 110 to the display device 150, the display devices in the order of “A, B, B, C” with respect to the data for 0 to 2 minutes that are equal to or less than the second set time X are displayed. 150 is displayed.
From the viewpoint of grasping the entire component mounting system 400 including the plurality of component mounting apparatuses 200, the worker can display the order of component shortage notice for each component mounting apparatus 200 as described above, so that the operator can display the component mounting system 400. In the arrangement order of the component mounting apparatuses 200, it is possible to determine which component mounting apparatus 200 preferentially replenishes components, for example, in relation to the current position of the operator.

  In the next step 107, the extraction unit 112 of the notice determination unit 111 targets the component outage times Zt in all the component supply apparatuses 1 obtained in step 105, and the first set time Y, which is the time for component outage recommendation recommendation. All of the component outage times Zt-1 that are the following component outage times are extracted. Since the component supply device 1 having these component expiration times Zt−1 is a supply device that requires component replenishment, the component expiration time Zt−1 is an object to be examined in step 109. On the other hand, for the part cut-off time Zt exceeding the first set time Y, it is not necessary to replenish the parts at this point, so in step 108 the part supply device 1-1 having the part cut-off time Zt is cut out of the parts. Exclude from the notice. By the above extraction operation and exclusion operation, it is possible to reduce the population to be examined for advance notice and execute the advance notice process at a higher speed.

  In the next step 109, the extraction unit 112 further selects all the component outage times Zt−2 that are component outage times equal to or shorter than the second set time X that is the component outage recommendation time among the component outage times Zt−1. Extract. The component supply device 1-2 having such a component expiration time Zt-2 is a supply device that needs to perform component replacement work urgently. Therefore, when the component time-out time Zt-2 is extracted, if the mounting operation is continued as it is, the operation of the component mounting apparatus 200 including the equipment, that is, the component supply apparatus 1-2 will be stopped. Therefore, in step 109, when the part-out time Zt-2 is extracted, a warning is displayed on the display device 150. In the warning display, when a plurality of component expiration times Zt-2 are extracted, the component mounting system 200 including the component supply device 1 corresponding to these component expiration times is arranged at the head in the component mounting system 400. The component mounting apparatus currently displayed is displayed at the top, and the corresponding component mounting apparatus 200 is displayed according to the arrangement order of the component mounting apparatuses 200 in the component mounting system 400. When the arrangement order is the same, the components are displayed in the order of the Z-axis number of the component supply device 1 corresponding to each component expiration time Zt-2, and each component expiration time Zt-2 is displayed.

  By providing the second set time in step 109, it is possible to further narrow down the target component supply devices that require the component outage notice. Therefore, by executing the component outage notice for the component supply device that exceeds the second set time and has the component outage time within the first set time, the component outage notice can be executed at higher speed. Also, by issuing the warning in step 109, it is possible to prompt the operator to replenish parts as soon as possible. Therefore, it is possible to reduce the occurrence of component breakage compared to the conventional case, and thus it is possible to improve the production efficiency and the work efficiency of the operator.

In the next step 110, for the component supply device 1-2 having the component expiration time Zt-2, the component remaining number Zv of each component supply device 1-2 is less than the minimum component remaining number Zl. Extract the remaining number. The extraction operation using the minimum component remaining number Zl is one of the characteristic operations in the present embodiment, and corresponds to one of the operations for determining the component replenishment order in consideration of the component replenishment condition information 123a.
The minimum component remaining number Zl is a component remaining number that is set for each component supply device and is the minimum required for component replenishment work. The remaining number extraction less than the minimum component remaining number Zl is executed by the second comparison unit 114b of the notice determining unit 111, and the minimum component remaining number Zl is read from the component replenishment condition information storage unit 123. The component supply device 1-3 that is less than the minimum remaining component number Zl corresponds to a supply device in which the electronic component 2 has been supplied to the extent that the component replenishment operation cannot be performed. Therefore, when the component supply device 1-3 that is less than the minimum remaining component number Zl is extracted, the notice determination unit 111 gives a warning of an equipment stop instruction to the component mounting device 200 having the component supply device 1-3. To emit. In response to the facility stop instruction, for example, the operator stops the facility and replaces the component of the component supply apparatus 1.
By performing the remaining number management for stopping the equipment in this way, it is possible to notify the operator that an urgent part replacement is necessary. Therefore, even if the equipment is stopped, the equipment stop time can be shortened, and the production efficiency and the work efficiency of the worker can be improved.

In the next step 111, information that does not meet the conditions of the above-described steps 109 and 110, that is, information on the part-out time exceeding the second set time and within the first set time is extracted by the extraction unit 112. To do. Note that the information that was not extracted, that is, the information subject to warning in step 109 and the information subject to equipment stop instruction in step 110 have already received a warning or the like as described above. At 112, the part is excluded from the target of the notice of running out of parts.
In this way, by executing the part-out notice for the parts supply device 1-4 having the part-out time within the first set time that exceeds the second set time, the part-out notice is executed at a higher speed. Can do.
Based on the part-out time information extracted by the extraction operation in step 111, display is performed on the display device 150 according to the following priority order. That is, first, the parts out time is arranged in order from the shortest. If the component run-out times are the same, the components are arranged from the top according to the arrangement order of the component mounting apparatuses 200 in the component mounting system 400. Further, when they are the same in the same equipment, they are arranged in ascending order according to the Z-axis number of the component supply apparatus 1 in the component mounting apparatus 200.

In step 113 to step 120 described below, the workability related to the work when the parts replenishment work is performed for the parts supply device 1-4 having the part time-out information extracted in step 111 is further increased. Consider running out of parts in consideration.
More specifically, the worker replenishes the corresponding component supply device 1 in accordance with the order of the component cut-off notice obtained in step 111. While the components are being replenished to the supply device 1, the other component supply devices 1 continue to supply the components, and the remaining number of components changes every moment. Therefore, first, in step 113, when the component replenishment is executed according to the order of component expiration notice in the component supply device 1-4 extracted in step 111, with the component expiration time information extracted in step 111 being the target. The remaining part number determination unit 113b of the notice determination unit 111 obtains a provisional remaining number Zc that is the remaining number of parts at the time when the component replenishment is performed in each of the component supply apparatuses 1. As a method of obtaining, the number of parts consumed until the part replenishment is subtracted from the number of remaining parts Zv obtained in step 102. The number of consumed parts is obtained as follows. For example, taking the part supply device R having the third highest part order notice order as an example, the parts out notice order will be first and second before the parts supply is executed in the part supply apparatus R. The parts are replenished for the parts supply devices P and Q. Therefore, the part replenishment work time C required in the two parts supply devices P and Q is obtained, and the time is divided by the production tact until the parts replenishment is executed in the part supply device R. Determine the number of circuit boards to be manufactured. Then, the number of consumed parts of the component supply device R is obtained by multiplying the number of circuit boards by the number of components that the component supply device R supplies per board. Then, the component temporary remaining number Zc is obtained by subtracting the consumed component number from the initial component remaining number Zv. Here, the component replenishment operation time C is stored in the component replenishment condition information storage unit 123 and is read and used for each component supply apparatus 1.
The part remaining number determination operation using the part replenishment operation time C is one of the characteristic operations in the present embodiment, and corresponds to one of the operations for determining the component replenishment order in consideration of the component replenishment condition information 123a. To do.

In the next step 114 and step 116, for each component provisional remaining number Zc obtained in step 113 for each component supply device 1-4 having the component expiration time information extracted in step 111, the notification determining unit 111 The 1 comparison unit 114a compares the maximum component remaining number Zh. The maximum number of remaining parts Zh is the maximum number of remaining parts provided for each component supply device 1 and capable of performing the component replenishment operation, and is stored in the component replenishment condition information storage unit 123 and read for each component supply device 1. Issued and used. More specifically, when the parts supply device is, for example, the parts feeder, the parts are supplied by feeding out the tape 3 from the reel 4, so when the number of remaining parts is excessive when the parts are replenished. The end portion of the tape 3 is still wound around the reel 4 and the parts replenishment operation cannot be performed. Therefore, the maximum number of remaining parts that can be replenished with parts is set as the maximum remaining number of parts Zh.
The component remaining number determination operation using the maximum component remaining number Zh is one of characteristic operations in the present embodiment, and corresponds to one of operations for determining the component replenishment order in consideration of the component replenishment condition information 123a. To do.
As a result of the comparison, the component temporary remaining number Zc is equal to or larger than the maximum component remaining number Zh, that is, the end portion of the tape 3 is still wound around the reel 4 as described above. Is excluded from the comparison operation with the maximum remaining component number Zh in step 115. By this exclusion, it is possible to further narrow down the target for which the parts-out notice is required, and to execute the parts-out notice at a higher speed.

Further, the parameter to be compared is changed by the above-described exclusion operation by the comparison operation with the maximum remaining component number Zh in step 114. That is, the temporary component remaining number Zc may change. Therefore, every time the above-described exclusion operation is executed, the process returns to step 113, and the component provision remaining number Zc is again obtained for each component supply apparatus 1 in each component supply apparatus 1 to be newly compared. Update. The component temporary remaining number updated in this way is assumed to be an updated component temporary remaining number Zcn.
In steps 114 and 116, for all the comparison targets, the above exclusion and update operations are continued until the component temporary remaining number Zc or the updated component temporary remaining number Zcn is less than the maximum component remaining number Zh.

For the information determined that the component temporary remaining number Zc or the updated component temporary remaining number Zcn is less than the maximum component remaining number Zh, the component temporary remaining number Zc or the update is further performed in the following steps 117 and 119. For each temporary component remaining number Zcn, the second comparison unit 114b of the notice determination unit 111 performs comparison with the minimum remaining component number Zl. The component remaining number determination operation using the minimum component remaining number Zl is one of the characteristic operations in the present embodiment, and corresponds to one of operations for determining the component replenishment order in consideration of the component replenishment condition information 123a. To do.
When the comparison operation finds component remaining number information in which the component temporary remaining number Zc or the updated component temporary remaining number Zcn is less than the minimum component remaining number Zl, that is, the component cannot be replenished as described above. When the component replacement required component supply device 1-R, which is a component supply device whose remaining number is reduced and needs component replacement, is found, the following processing is performed at step 118.

That is, in the parts out-of-order notice order based on the part temporary remaining number Zc or the updated part temporary remaining number Zcn obtained in steps 114 and 116, that is, in the part replenishment order, the parts are replaced by the parts replacement-required parts supply device 1-R. The maximum component remaining number in step 114 is changed from the component supply device 1 with the fast replenishment order to the maximum component supply device 1-M having the maximum component expiration time corresponding to the component temporary remaining number Zc or the updated component temporary remaining number Zcn. Excluded from comparison with Zh.
By the above-described exclusion operation, it is possible to further narrow down the target that requires the part-out notice and execute the part-out notice at a higher speed.

  Further, since the parameter group, that is, the comparison target is changed by performing the exclusion operation in step 118, the part temporary remaining number Zc or the updated part temporary remaining number Zcn may change. Therefore, after step 118, the process returns to step 113, the parts provisional remaining numbers are again obtained for all the parts supply devices belonging to the new population after the exclusion, and the parts provisional remaining number Zcn is updated. To do. Then, the operations of steps 114 and 116 and the operation of step 117 are repeated again based on the new updated component temporary remaining number Zcn. In the following description, the term “updated part temporary remaining number Zcn” is also used for the new updated part temporary remaining number Zcn.

  The exclusion operation in step 118 described above will be specifically described with reference to FIGS. FIG. 8 shows various conditions in the example for explanation. That is, in this example, there are three component mounting devices A to C as the component mounting device 200, each of the component mounting devices A and B includes four component supply devices 1, and the component mounting device C includes Two parts supply devices 1 are provided. In addition, the order of parts out notice is assumed to be the order of component mounting apparatuses A, B, and C. Further, FIG. 8 shows the “number”, that is, the number of parts to be supplied for manufacturing one circuit board, the part temporary remaining number Zc, or the updated part temporary remaining number Zcn in each component supplying apparatus 1. "Remaining number", "Remaining time" until component breakage occurs in the remaining number, "Maximum number" corresponding to the above-mentioned maximum remaining component number, and "Minimum number" corresponding to the above-mentioned minimum remaining component number Has been. For convenience of illustration, the maximum remaining component number is described only for the third component supply device of the component mounting device B, and the minimum remaining component number is the second component supply device of the component mounting device B and the second component supply device C. Although only the component supply device is described, as described above, the maximum number of remaining components and the minimum number of remaining components are set for each component supply device.

  Under such conditions, in the comparison operation in step 117, for example, the component temporary remaining number Zc or the updated component temporary remaining number Zcn in the fourth component supply device of the component mounting apparatus B is the same as that of the fourth component supply device. It is assumed that it is determined that the minimum remaining component number KK4 is smaller. In this case, in step 118, the following operation is executed. That is, from the range corresponding to the component mounting device and the component supply device having a component replenishment order earlier than the fourth component supply device, that is, from the first component supply device to the fourth component supply device and the component mounting of the component mounting device A From the range of the first component supply device to the third component supply device of the device B, the extraction unit 112 selects the one having the longest component out time. In this example, as shown in FIG. 9, in the above range, “24 minutes” having a margin in the range before the fourth component supply device of the component mounting device B and having the maximum component run-out time is selected. The fourth component supply device of the component mounting device A having the component expiration time “24 minutes” is extracted. Therefore, the fourth component supply device of the component mounting device A is excluded from the comparison operation with the maximum component remaining number Zh.

  After step 118 is executed as described above, the operations of steps 113 to 116 are executed again, and step 117 is executed again. In step 117, as shown in FIG. 10, for example, it is determined that the updated component temporary remaining number Zcn in the second component supply device of the component mounting apparatus C is smaller than the minimum component remaining number LL2 of the second component supply device. Suppose. Therefore, in step 118, from the range corresponding to the component mounting apparatus and the component supply apparatus having a component replenishment order earlier than the second component supply apparatus of the component mounting apparatus C, that is, from the first component supply apparatus of the component mounting apparatus A. From the range of the first component supply device of the four component supply device, the first component supply device of the component mounting device B, the second component supply device, the fourth component supply device, and the first component supply device of the component mounting device C, the component outage time is the maximum. The extraction unit 112 selects a thing. In this example, as shown in FIG. 10, in the above range, “24 minutes”, which has a margin in the range before the second component supply device of the component mounting device C and has the maximum component run-out time, is selected. The first component supply device of the component mounting device C having the component expiration time “24 minutes” is extracted. Therefore, the first component supply device of the component mounting device C is excluded from the comparison operation with the maximum component remaining number Zh.

  After the operation of step 118, in step 119, until all the updated component temporary remaining number Zcn or the component temporary remaining number Zc becomes equal to or larger than the minimum component remaining number Zl, in other words, the component replacement required component supply device 1-R exists. The operations in steps 113 to 118 described above are repeated until no more. When all the updated part temporary remaining number Zcn or the part temporary remaining number Zc is equal to or larger than the minimum component remaining number Zl, that is, when the final part-out notice order is obtained, in step 120, the part-out notice order, The component replenishment order is displayed on the display device 150. FIG. 11 shows the final part-out notice order in the above example. This completes the part-out notice operation.

  As described above, according to the part run-off notice method of the present embodiment, parts replenishment condition information, which has not been considered at all in the past, is set for each part supply device, and the part replenishment order is determined when the order of parts replenishment is obtained. The parts replenishment order is obtained in consideration of the replenishment condition information, and the parts are cut out according to the parts replenishment order. Therefore, since the part replenishment order can be determined with higher accuracy than in the prior art, it is possible to reduce the occurrence of out of parts as compared with the prior art, thereby improving the production efficiency and the work efficiency of the operator. it can.

  Further, in the above-described component run-off notice method, the component replenishment order is obtained in consideration of the workability related to the component replenishment work, which has not been considered at all in the past. Considering the above workability, it is possible to determine the part replenishment order with higher accuracy than in the past, so it is possible to reduce the occurrence of parts shortage compared to the conventional case, thus improving the production efficiency and working by the operator. Efficiency can be improved.

  The component run-out notice method of the present invention can be applied to a component run-out notice in a component supply apparatus that is provided in a component mounting apparatus for mounting an electronic component on a circuit board and supplies the electronic component.
