Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a method for centrally controlling a large number of looms.
In particular, the present invention relates to a method in which control data and yarn information necessary for weaving are stored in advance in a central control device together with a unique number, and the data are automatically transferred to the control device of each loom when necessary.

Prior Art For example, the invention disclosed in Japanese Patent Application Laid-open No. 59-211658 uses a method for controlling a group of looms in which a central host CPU issues a command to the microcomputers of each loom to stop or prohibit starting of the looms.

However, this group control method only provides information on stopping or prohibiting the start of the loom, and is not involved in controlling the weaving conditions during operation.

When actually operating a loom, for example on an air jet loom, the number of rotations of the loom's drive motor, the number of weft threads, the warp thread tension settings, the timing of opening and closing of the weft insertion nozzle, the timing of weft insertion, etc. A large amount of control data such as air pressure settings is required.

These control data can be set remotely from each loom by inputting them into the control device of each loom through the terminal of each loom using a central control device. However, if these large amounts of control data were input centrally for each parameter, it would be difficult to
Data input operations are complicated, labor cannot be saved, and central management functions cannot be fully utilized.

On the other hand, during the spinning process of the warp and weft yarns, various types of yarn information, such as yarn length, maximum winding diameter, and defect information during the yarn spinning process, are recorded. Conventionally, this information has rarely been used, and even if it were to be used, the yarn information would have to be entered for each warp supply beam and weft supply cone of each loom. . Therefore, the input operation becomes complicated.

OBJECTS OF THE INVENTION Therefore, an object of the present invention is to make it possible to easily transfer weaving control data necessary for the actual operation of each loom from a central control device to the control device of each loom, and also to centrally transfer yarn information. so that it can be sent from the loom to the control device of each loom,
The goal is to achieve optimal control.

SUMMARY OF THE INVENTION Therefore, the present invention stores weaving control data for each type of textile in the memory of a central control device in advance in association with the type number, and specifies the type number when changing the type of each 1a machine. This allows all control data necessary for weaving to be read from memory and immediately transferred to each corresponding loom control device. In addition, in order to effectively utilize the yarn information in the weaving process, the present invention stores information in the yarn reeling process necessary for weaving in the memory together with the beam number and loft number, and stores the information on the warp beam and weft. When changing the cone of a loom, this information is entered into each corresponding loom control device. Therefore, in the present invention, the control data necessary for weaving can be easily specified on the central controller side and this control data can be transferred to each loom, and the optimal operating state can be set for each loom according to the thread information. can be realized.

Configuration of Centralized Control Device First, FIG. 1 shows the configuration of a centralized control device 1 that is the premise of the centralized control method of the present invention. This central control device 1
is equipped with a central control device 2 as a main part. A CPU 5 inside the central control unit 2 is connected to an input device 7 such as a keyboard, an output device 8 such as a printer, an external memory 9, and an interface 10 via an input/output capotro. On the other hand, the terminal device 44.
4□...44 is the control device of the loom 31%3□
...Connected to 3fi, and also interfaces 11+, llz...11n, and data bus 12
The CPU 5 is connected to the CPU 5 via the interface 10 described above.

Under the control, calculation, and storage functions of the CPU 5, the central control device 2 takes in necessary control data to the control devices 31.3□...3□ of each loom according to a control program, and stores it in the memory 9. Then, control device 3 of each loom
1.3□ . . . Based on the request from 37, necessary control data is transferred through the data bus 12.

Such control data is used for human-powered devices such as keyboards 7
It is inputted via a woven fabric, is created while checking on an output device 8 such as a display, and is stored in the memory 9 together with a product number unique to the textile product after creation. In this way, for each type number, for each type of fabric, the number of rotations of the loom per unit time, the number of weft threads per unit length, the warp thread tension during weaving, and the on/off status of the weft insertion nozzle. Data on timing, pressure setting of wefting air, and other necessary weaving conditions are created in advance and stored in the memory 9. Therefore, subsequent designation of control data is easily performed by specifying only the product number.

The contents of the control data set in this way are as follows:
It is changed as necessary, and it is changed each time actual weaving or trial weaving is performed in order to achieve the optimum conditions.

FIG. 2 shows the procedure for changing internal control data for each product number. The operator uses the input device 7 to
When "change product type" is selected, the program necessary for changing the product type is automatically started. When the product number to be changed is designated here, the CPU 5 reads the control data of the designated product number from the memory 9 and displays it on the output device 8 or the like. Then, the operator selects the item to be changed from the control data and changes the numerical value to the required value. After such a change, the CPU 5 stores the changed control data in the memory 9 as new data for the product number.

In this way, the product type is changed.

On the other hand, the yarn information is stored inside the memory 9 together with the beam number of the warp yarn beam and the loft number of the weft yarn cone. Such beam numbers and lower) numbers are pre-marked on the beams and cones in preparation for weaving. The warp yarn information includes the total length of the yarn, the outer diameter of the beam, and information about defects such as fuzz, uneven adhesive, and yarn breakage in previous processes, such as sizing. In addition, the weft thread information includes data such as the manufacturing process, that is, defect information such as thread breakage in the loft, as well as thread length and thread thickness.

In this way, the central control device 2 stores the control devices 38.3□...37 of each loom in the memory 9 external to the CPU 5.
For each loom, a series of in-process data, that is, for each loom number, control data, that is, its product number, warp beam number, and weft start/stack number are sequentially stored as a queue.

Structure of the Invention Next, FIG. 3 shows the sequence according to the centralized control method of the present invention.

This centralized control is executed by a centralized control program inside the CPU 5. First, when the CPU 5 receives a command to start centralized control, it starts the control, specifies a loom number, for example, "1", and
Receive the necessary data from 1. This terminal 4. In addition to providing the data necessary for controlling the corresponding loom to the loom control device 3I, it also takes in the signals necessary for weaving from the corresponding loom, temporarily stores them, and transmits the data from the central control device 2. Upon receiving the transfer command, it is transferred to the CPU 5.

Here, the CPU 5 determines from the received data whether or not there is a data request for the control device 3I of the loom. Its control device 3. When requesting data,
The CPU 5 reads the in-process data from the external memory 9 and specifies the product number, the warp beam number, and the weft loft number, reads out the control data and yarn information corresponding to the numbers, and sends the data to the interface 10. Bus 12 and interface 11
1 to the corresponding terminal device 41.

Here, the terminal device 41 stores the transferred product number control data and thread information, and stores the control data and thread information of the corresponding loom. The system retains the data necessary for the operation of the system, and performs the necessary controls based on this data. In addition, yarn information, especially yarn defect data, can be used to temporarily change the rotation speed of the loom near the defective yarn.
Low (Used for setting etc.

On the other hand, the CPU 5 reads the next loom number, for example "2", and performs similar processing on it.

In this process, the control devices 3I, 3□...3,
When there is no request for control data, the CPU 5 branches from the data transfer routine, enters the registration routine, and sequentially judges whether to register the product type, whether to register the beam, and whether to register the loft number.

When a model number registration has been issued and the machine is ready for registration, the operator first inputs the model number, then inputs the control data corresponding to the model number, and then issues a data registration command. Through such operations, the central control device 2 registers control data for each product number.

Also, when a beam registration request or loft registration request is issued and registration is possible, the operator must input the loom number, then the product type number, and then the corresponding beam number and its thread information. The corresponding cone number and weft thread information are input and registered in the external memory 9 as work-in-progress data.

In this way, the loom number, the corresponding product number, beam number, and loft number are input in advance to all looms as in-process data into the central control device 2.
be registered.

Next, FIG. 4 shows another embodiment of the centralized control method of the present invention.

First, after starting the centralized control, the CPU 5 controls the control bag W3 of the loom. ．． 3□: Determines whether there is a request to transfer control data from 3fi. For example, the control device 3 of a loom
．． When a transfer request is received from the CPU 5, the CPU 5 starts a data transfer routine and first determines whether the data requested to be transferred is control data for the product type. Proceed to the next step and transfer the required yarn information, but if control data is requested due to a change in product type, search for the product number of the next product in progress, and use that number to obtain the necessary control data. After reading and transferring the information, the yarn information is transferred to the control device 3 of the loom based on the warp beam number and the weft lot number.

Such operations can be performed on other control devices32...3. By sequentially repeating , the central controller 2 can:
The control devices 31.3□...37 of all the looms will be centrally controlled.

When determining the control data transfer request, if there is no data transfer request, the CPU 5 enters a registration routine and determines whether the operator has registered the type, yarn information, and transfer order. CP when the operator newly inputs the product number and corresponding control data.
When the command for type registration is given to U5, the step of type registration is started. Therefore, after registering the product number, the operator sequentially inputs control data corresponding to the product number. In this way, all varieties are registered. At the end of such product registration, the control program returns to the first step again.

Also, when the operator requests yarn information registration,
CPU 5 starts the program.

Therefore, after registering the beam number and loft number, the operator must sequentially input the yarn information of the weft and warp yarns. Once all inputs have been completed, the control program returns to the first step.

Further, the operator issues a request for registering the transfer order, and the central control device 1 starts this step. Therefore, after specifying the i machine number, the operator inputs the product number while specifying the transfer order based on the weaving order of the loom, and then inputs the corresponding beam number and loft number in sequence.

In this way, for example, regarding the control device 31 of a loom,
When the product number to be woven, the warp beam number, the weft cone loft number, etc. are specified, they are inputted in order of transfer.

Therefore, with this control program, even if it is not determined in advance to which loom the warp beam, weft cone, etc. will be supplied, various data can be entered in advance, and the in-process data can be input at the stage when they are identified. It is advantageous to create.

Effect of the invention The present invention provides the following unique effects.

First, since the control data necessary for weaving is input to the central control device by product number, the control data can be easily transferred to the control device of each loom by specifying the product number.

In addition, along with these control data, the warp and weft thread information is registered in advance in the central control device by beam number and loft number, so the thread information can be immediately read from the beam number and loft number. Therefore, this information is effectively used as control data together with the control data necessary for weaving, so that optimal operating conditions can be achieved.
