Description

  The present invention relates to a separator and a plate material processing system including the separator.

  Conventionally, in a plate material processing system that performs many so-called multi-piece picking-up of the same type of product from a single sheet of standard material, there is a technique in which products are sequentially accumulated in the next area when the product reaches a specified accumulation height. It was adopted. On the other hand, in a plate material processing system using a laser processing machine or NC punch press to realize a synchronous production system for demand, a plurality of different types of products are arranged (nested) on a single standard material, and the same type Even products are processed in a variety of ways, such as vertical and horizontal free placement, so products that are cut out from standard materials are individually transported and sorted according to the characteristics of the products at the time of transport. There is a demand to do.

  However, in such a synchronous production method, because the product placement prioritizes the yield of the material (stable material), the processing proceeds in a state where the same product is spread over several to tens of materials, When products are sorted according to their characteristics and collected, the cut products will be arranged in different areas at any time until the same product appears. When using a standard unloading pallet, multiple unloading pallets are required. It will be.

  For this reason, for example, in a system in which individual carry-out pallets are taken out from the product shelves and accumulated, it takes a few minutes to put in and out the pallets, and thus it takes a considerable time to complete the carry-out of the products. Therefore, especially when the unloading loader enters the interference area of the plate processing machine and performs the unloading operation, the plate processing machine cannot be operated until the final product has been unloaded, and a decrease in productivity can be avoided. Absent.

  Therefore, it has been proposed to determine a sorting order and product arrangement based on characteristic information (for example, delivery date, type of post-process, shape) of the product, and generate a machining program so as to process in this sorting order. (Patent Document 1).

JP 2000-158301 A

  However, in Japanese Patent Laid-Open No. 2004-260260, product placement is prioritized in the sorting order. Therefore, product placement in consideration of the yield of the material cannot be performed, and there is a problem that the material is wasted.

  An object of the present invention is to provide a separator capable of reliably sorting products according to their characteristics without impeding productivity when individually carrying out products even when product placement is performed in consideration of material yield. It is providing the board | plate material processing system provided with this.

The separator of the present invention is a separator that sorts, loads, and stores products processed by a plate material processing machine, and accommodates a plurality of mounting tables arranged above and below, and the plurality of mounting tables a frame that is, these mount table and a moving means for moving individually, as the movement position of the mount table, a loading position for loading onto the placing table the products from above the frame, A storage position for storing the product in the separator, and a take-out position that an operator directly uses on the extension of the movement between the loading position and the storage position are set. the drive signal generated based on the product information of the product to be processed by the plate material processing machine is driven to move the mount table to which the product is loaded, placed tables of the plurality of stages Is provided with an extending portion that extends to the opposite side of the storage position when the mounting table is in the loading position and to which the moving means is coupled. substantially the entire table is characterized that you have moved onto the storage position side extended in a state of being withdrawn from the frame.

The plate material processing system of the present invention loads and stores a plate material processing machine that processes a plate-shaped material, a loader that unloads a product obtained by processing with the plate material processing machine, and a product that is unloaded by the loader loader. A separator control unit that generates a drive signal to be output to the moving means of the separator based on the product information of the product, and the plate material processing machine, the unloading loader, and the separator are in a series of flow processes. The loading position of the separator and the loading position of the separator are close to each other, and the loading loader moves between the loading position and the loading position. Features.

  In the above, according to the present invention, based on the product information of the product to be processed, the product carried out from the plate material processing machine can be instantly moved by moving the mounting table for loading the product to the loading position. Can be loaded and stored. Therefore, for example, even when products of the same shape are not sequentially carried out, the same mounting table can be called and loaded at the same position in a short time each time products of the same shape are carried out. In other words, by preparing one separator, it is the same as securing a larger loading area. Thus, every time a product that needs to be loaded at the same location is carried out, There is no need to take out and arrange the unloading pallet, so that the loading operation can be greatly simplified and the productivity can be improved. Since the productivity is not hindered even if the products having the same shape are not carried out continuously, the nesting of the products with respect to the material can be optimized with the yield priority.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a configuration of a plate material processing system 1 according to the present embodiment. FIG. 2 is a plan view showing each device constituting the plate material processing system 1 and its arrangement.

The machining program is an NC program normally used for a CNC machining machine. The product information acquired by the unloader 5 includes the product number of the product to be processed, the pallet number (shelf number) for specifying the unloading pallet for loading the unloaded product, and the product at any position in the unloading pallet. X- and Y-coordinates of palette reference for specifying whether or not to be accumulated. Of these products, the same product number is assigned to products having the same characteristics, such as the same shape or the same post-process. The products having the same product number are accumulated at the same position on the same carry-out pallet.

  A machining command is transmitted from the cell controller 8 to the plate material processing machine 4, and machining according to a designated program is performed by this command. By this processing, a plurality of different types of products are cut out from one material. On the other hand, prior to actual machining, the plate material processing machine 4 outputs the carry-in information to the carry-in loader 3, and the carry-in loader 3 transmits the pallet number information in the carry-in information to the stocker 2. As a result, the stocker 2 takes out the material stored in the carry-in pallet of the designated pallet number, and the carry-in loader 3 carries it into the plate material processing machine 4.

  Further, the plate material processing machine 4 transmits unloading information and loading information to the unloading loader 5. The carry-out information includes final processing position coordinates (X coordinate, Y coordinate: final punch position, which is a processing machine reference coordinate) of each processed product, product suction position coordinates, the product number, and the like. The loading information includes a command to specify whether or not to apply a curing sheet after product loading, whether to release following the previous product when loading the product, or whether to release from the top of the previous product Contains the command to be specified.

  Here, as shown in FIG. 2, the loading loader 3 includes a carrier 32 having a plurality of vacuum cups 31 in the X-axis direction (the direction toward the plate material processing machine 4, the left-right direction in the figure) and the Z-axis direction. It is the structure which moves to (front and back direction in a figure). When moving in the X-axis direction, the carrier 32 moves on a guide frame 33 provided from a material suction position in the stocker 2 to a downstream release position. The material release position may be the material clamping position in the plate material processing machine 4, but may be in front of the clamping position. When releasing before the clamp position, a conveyor or the like for moving the released material to the clamp position is provided. The vacuum cup 31 is arranged so as to be able to adsorb large and small size materials.

  The plate material processing machine 4 is a press center equipped with a gatling mechanism that accommodates 300 to 500 types of dies in a replaceable manner, and in addition to normal blanking processing, half piercing, cutting and bending, burring, drawing, projection, louvering , Reinforcement beads, and cutting and drawing can be performed. However, in addition to such a press center, a turret punch press that mainly performs blanking may be used.

  In the plate material processing machine 4, a carriage 42 having a plurality of clamps 41 is movable from the clamp position 4A in the X-axis direction (left-right direction in the figure) and Y-axis direction (up-down direction in the figure). The position where both have moved to the maximum is shown in the figure as the maximum moving position 4B. The upper position of the clamp position 4A in the figure is a processed product carry-out position 4C (carriage not shown).

  The carry-out loader 5 includes a carrier 52 provided with a number of vacuum cups 51. The carrier 52 moves in the Y-axis direction (vertical direction in the drawing) along the horizontal portion 54 of the inverted T-shaped lifting rack 53, and the lifting rack 53 itself is a carry-out position 4C of the plate material processing machine 4. Is supported so as to be movable in the Z-axis direction (front and back direction in the figure) with respect to the guide frame 55 installed over the separator 6 and in the X-axis direction (left and right direction in the figure) along the guide frame 55 It can be moved freely.

  The carrier 52 is provided with a pair of expansion portions 56 that are advanced and retracted by a pneumatic cylinder (not shown). By using the vacuum cup 51 provided in the expansion portion 56, various shapes can be obtained. The cut product can be reliably adsorbed.

Below, the most characteristic separator 6 in this embodiment is explained in full detail.
As shown in FIGS. 3 to 5, the separator 6 includes a frame 61 assembled in a substantially rectangular parallelepiped shape. Inside the frame 61, there are a plurality of (in this embodiment, five) shelf (lower) First to fifth shelf steps 6A to 6E) are provided in order. In the positions corresponding to the respective shelf steps 6A to 6E, the placement table 62 is accommodated so as to be movable in the front-rear direction (in FIG. 3, the front and back direction in the figure, and in the right and left directions in FIGS. 4 and 5). .

  Specifically, a horizontal guide rail 63 along the front-rear direction is provided on each of the left and right sides in the frame 61 for each of the shelf steps 6A to 6E. A cam follower 64 is provided on one of the left and right side surfaces of the mounting table 62 that has a flat rectangular shape, and the cam follower 64 rolls along the guide rail 63. A guide bar 65 for liner motion guide (linear motion guide) is also provided on the other side of the frame. A slider 66 is provided on the other side surface of the mounting table 62, and the slider 66 is fitted with the guide bar 65 and slides.

  The guide rail 63 and the guide bar 65 are supported by appropriate vertical and horizontal support frames in the frame 61, and sprocket wheels 67 and 68 are attached to the support frame so as to be separated in the front-rear direction. A roller chain 69 is wound around the sprocket wheels 67 and 68. The roller chains 69 and the placement table 62 in each of the shelf steps 6A to 6E are connected by a bracket 70.

  The left and right sprocket wheels 68 provided on the rear side are connected by a drive shaft 71. The drive shaft 71 is received by a pillow-shaped bearing 72 provided at an appropriate position of the support frame described above. The drive shaft 71 is driven by a geared motor 73 with a speed reducer connected to one end thereof. Therefore, the mounting table 62 moves back and forth by forward / reverse driving of the geared motor 73.

  In this embodiment, the mounting table 62 includes the geared motor 73, the drive shaft 72, the sprocket wheels 67, 68, the roller chain 69, the guide rail 63, the guide bar 65, the cam follower 64, and the slider 66. The moving means of the present invention to be moved to is configured.

  Further, the carry-out pallet 74 is installed at a predetermined position on the mounting table 62 in a state where it is accurately positioned by a positioning pin or the like. The carry-out pallet 74 is handled by a forklift or the like, and the above-described pallet number (1 to 5) designated by the product information is assigned to such a carry-out pallet 74 corresponding to each shelf 6A to 6E. ing. For example, the pallet number (1) is assigned to the carry-out pallet 74 installed on the lowermost shelf 6A, and the pallet number (5) is assigned to the carry-out pallet 74 installed on the uppermost shelf 6E. The

  Next, based on FIG. 4, FIG. 5, the shelf steps 6C-6E are demonstrated first. In the shelves 6C to 6E, the right side position in the figure, that is, the rear side position, is the loading position A, and the left side position in the figure, that is, the front side position, is the storage position B. When loading the product adsorbed by the unloading loader 5 from the plate material processing machine 4, the mounting table 62 has moved to the loading position A, and after the loading to the unloading pallet 74 by the unloading loader 5 is completed, the storage position B Move to.

  Then, which loading table 62 (unloading pallet 74) is moved to the loading position A according to the product is determined on the unloading loader 5 side based on the product number and pallet number included in the product information of the product. The separator control unit 50 provided in the controller determines and controls the separator 6.

  That is, on the unloading loader 5 side, since the product numbers and pallet numbers of all products cut out by the plate material processing machine 4 are known in advance from the product information from the scheduler 7, the unloading loader 5 is on the plate material processing machine 4 side. The unloading operation is started based on the unloading information with the unloading command from the unloading machine as a trigger, and the unloading pallet 74 for loading products is judged from the product number and pallet number and moved to the loading position A. Specifically, a drive signal for the geared motor 73 corresponding to the mounting table 62 to be moved is output from the separator control unit 50 on the carry-out loader 5 side. The separator control unit 50 includes software (computer program) executed by the controller and appropriate hardware.

  From the above, for example, when a product is loaded on the unloading pallet 74 of the shelf 6C, the unloading pallet 74 has been moved to the loading position A, but the shelf 6D positioned above the unloading pallet 74. , 6E is located in the storage position B, so that the product loading operation by the carry-out loader 5 can be performed without any trouble. On the other hand, the unloading operation of the unloading pallet 74 by the forklift is performed when the unloading pallet 74 is at the storage position B. The above control of the loading position A, the storage position B, and the separator 6 is the same in the shelves 6A and 6B.

  Accordingly, even when a plurality of types of products having different shapes are optimally nested across a plurality of materials, and the same shape of products cannot always be carried out continuously, the same unloading pallet 74 is loaded each time products of the same shape are unloaded. It is only necessary to move horizontally to the loading position A, and the loading operation can be easily realized in a short time. For this reason, since it is not necessary to perform the troublesome work of taking out the unloading pallet from the product shelf with the forklift and arranging it in the area on the unloading loader side, productivity can be greatly improved. Furthermore, since it is not necessary to perform nesting in consideration of the product delivery order, optimal nesting in consideration of yield can be performed, and waste of materials can be eliminated.

  By the way, in shelf 6A, 6B, as shown in FIG.4, FIG.6, FIG.7, the mounting table 62 has the extension part 62A extended greatly on the back side, and this extension is accompanied. The roller chain 69 is also extended, and the drive shaft 71 is also located on the rear side. In such a configuration, the extending portion 62A of the mounting table 62 and the roller chain 69 are connected. For this reason, in the shelf steps 6A and 6B, the loading table 62 is moved to the forefront in addition to the loading position A and the storage position B shown in FIG. As shown in FIG. 7, it can be located at the extraction position C drawn forward from the frame 61.

  The movement of the placement table 62 to the take-out position C may be performed by a predetermined program, or may be performed by an interrupt operation or the like during operation with a predetermined program. Then, by moving the mounting table 62 to the take-out position C, the operator can take out the product directly from the carry-out pallet 74, which is effective when it is necessary to carry the product immediately into the next process. Moreover, since the take-out position C is set on the extension of the movement between the loading position A and the storage position B, an extending portion 62A is provided on the mounting table 62, or a long roller chain 69 is used. This can be realized with a simple structure.

  Moreover, according to the separator 6 of this embodiment, for example, by storing a curing sheet in advance on the unloading pallet 74 in the uppermost shelf 6E, the curing sheet is loaded after the product is loaded on the lower unloading pallet 74. The unloading pallet 74 loaded with the product is moved to the loading position A, the curing sheet is adsorbed by the unloading loader 5, and the unloading pallet 74 is returned to the storage position B, whereby the unloading pallet 74 loaded with the product is moved. It can also appear below and release a curing sheet on the product. It is effective to prevent the product from being damaged by loading the product. Whether or not to perform such work follows the instruction of the loading information described above.

The best configuration, method, and the like for carrying out the present invention have been disclosed above, but the present invention is not limited to this. That is, the invention has been illustrated and described with particular reference to certain specific embodiments, but without departing from the spirit and scope of the invention, Various modifications can be made by those skilled in the art in terms of quantity and other detailed configurations.
Therefore, the description limited to the shape, quantity and the like disclosed above is an example for easy understanding of the present invention, and does not limit the present invention. The description by the name of the member which remove | excluded the limitation of one part or all of such is included in this invention.

  For example, in the said embodiment, although the separator control part 50 was provided in the controller of the unloading loader 5, when the controller is provided in the separator 6 itself, you may provide the function of a separator control part in this controller. .

  INDUSTRIAL APPLICABILITY The present invention can be effectively used when a picking method (takeout method) in which a plurality of different types of products are cut out from a single material and the processed products are individually carried out is employed.
