Description

  The present invention relates to a plate material processing system that performs plate material processing by collectively managing from storage to processing of a material plate material.

  A plate material processing line that processes a plate material by a plate material processing machine such as a punch press often employs a plate material processing system that collectively manages from storage to processing of the material plate material. In the conventional plate processing system, a pallet loaded with various material plates is stored in an automatic warehouse, and a pallet loaded with necessary material plates is delivered to the vicinity of the plate processing machine, and a loader is used from this pallet. The raw material plate materials were separated one by one and supplied to the plate material processing machine.

  Since production lots have recently become smaller, the use of material plates of various sizes is increasing. For the purpose of increasing the yield of the material, it has been practiced to use a raw material plate cut according to the dimensions of the product plate material itself. However, if the production lot is small, the pallet must be frequently loaded and unloaded, and during that time, the plate material processing machine waits, causing a reduction in operating rate.

For example, Patent Documents 1 and 2 have been proposed as countermeasures when the production lot is small. Patent Document 1 arranges pallets loaded with necessary types of material plates on a pallet station in an automatic warehouse, and supplies the material plates from the pallet station pallet to the plate material processing machine, eliminating the need for pallet loading and unloading. It is a thing. In Patent Document 2, a target type and the number of material plate materials are mixedly loaded in advance on a pallet outside the automatic warehouse, and a product plate material is supplied from the pallet to a plate material processing machine.

  According to Patent Document 1, it is possible to improve the efficiency of supplying the material plate material to the plate material processing machine by the amount that pallet entry / exit is unnecessary. For this purpose, the material plate material is smoothly transported in the automatic warehouse. Need to be done. In the case of Patent Document 1, specifically, by combining a picking loader that lifts and conveys the material plate material from the pallet of the pallet station, and a traveling conveyor that receives the material plate material from the picking loader and carries it out of the automatic warehouse, We are trying to facilitate the transportation of material plates in automatic warehouses. However, there is a problem that the structure is complicated because two types of apparatus for conveying the material plate are provided. Further, when the material plate material is conveyed one by one from the automatic warehouse to the plate material processing machine, the conveyance mechanism becomes complicated.

  Further, according to Patent Document 2, since the target type and the number of material plate materials are mixedly loaded on the pallet and supplied to the plate material processing machine, the processing by the plate material processing machine can be performed efficiently. However, since the material plates are mixed on the pallet outside the automatic warehouse, the conveyance distance of the material plate from the storage location of the material plates in the automatic warehouse to the pallet outside the automatic warehouse is long, and the material plates are mixed on the pallet accordingly. It takes time to do. For this reason, a waiting time of the plate material processing machine is generated, leading to a reduction in operating rate.

Although there is also a loading / unloading control unit for unloading, the description thereof is omitted here.

The operations of the inter-pallet plate material transfer mechanism 20 and the positioning mechanism 37 under the control of the mixed pallet generation control unit 54 will be described with reference to the operation explanatory diagram of FIG. In FIG. 9, only the reference convex portion 37aX of the reference convex portions 37aX and 37aY of the positioning mechanism 37 is displayed to simplify the drawing.
In the initial state, as shown in FIG. 9 (A), by the stacker crane 6, the type pallets 10A, 10B, 10C on which the necessary types of material plate materials W are placed are arranged in the type pallet arrangement locations 12A, 12B, 12C. Yes. From this state, the inter-pallet plate material transfer mechanism 20 transfers, for example, the material plate material W1 of the type pallet 10A to the table 14a of the positioning location 14 ((B) in the figure).

  The material plate material W1 is transferred by issuing an output command to the travel drive source 26, moving the travel body 21 of the inter-pallet plate material transfer mechanism 20 above the type pallet 10A, and issuing an output command to the lift drive source 34. Then, the material plate material holder 22 is lowered, an output command is issued to the suction pad 29 to hold the material plate material W1, and an output command is issued to the lift drive source 34 to raise the material plate material carrier 22, and the travel drive source 26, an output command is issued, the traveling body 21 is moved above the positioning location 14, an output command is issued to the elevating drive source 34, the material plate material holder 22 is lowered, and an output command is issued to the suction pad 29. The held material plate material W1 is released, an output command is issued to the lifting drive source 34, and the material plate material holding body 22 is raised. In the operation of the inter-pallet plate material transfer mechanism 20, when the material plate material holder 22 is lowered at the specific pallet placement location 12A and the positioning location 14, the descent detector 36 detects that the material plate material W or the pallet 10 is lowered. Is supposed to stop. The same applies to the subsequent operation of the inter-pallet plate material transfer mechanism 20.

  When the material plate material W1 is transferred to the positioning place 14, the positioning mechanism 37 positions the material plate material W1. In the positioning method, first, an output command is issued to the positioning pusher 37bX, the material plate material W1 is pressed against the reference convex portion 37aX, positioning in the X direction is performed, and then an output command is issued to the positioning pusher 37bY, and the material plate material W1. Is pressed against the reference convex portion 37bY to perform positioning in the Y direction (see FIG. 5). Positioning in the X direction may be performed after positioning in the Y direction. During this positioning, the inter-pallet plate material transfer mechanism 20 transfers, for example, the material plate material W2 of the type pallet 10B to the temporary placement place 13 as the next material plate material (FIG. 3C). The transfer method is the same as described above.

  When the positioning of the material plate material W1 at the positioning location 14 is completed, the inter-pallet plate material transfer mechanism 20 transfers the material plate material W1 to the mixed pallet 10D arranged at the mixed pallet arrangement location 15 (FIG. D)). Subsequently, the material plate material W2 at the temporary placement place 13 is transferred to the positioning place 14 by the inter-pallet plate material transfer mechanism 20 ((E) in the figure). In the same manner as described above, the material plate W2 is positioned by the positioning mechanism 37. During this positioning, the inter-pallet plate material transfer mechanism 20 transfers, for example, the material plate material W3 of the type pallet 10C to the temporary placement place 13 as the next material plate material ((F) in the figure).

  The material plate W2 that has been positioned is transferred to the mixed pallet 10D by the inter-pallet plate transfer mechanism 20 ((G) in the figure). The material plate W2 is overlaid on the material plate W1. Since both of the material plate materials W1 and W2 are positioned at the positioning place 14, both the material plate materials W1 and W2 are aligned at one of the four corners. When the inter-pallet plate material transfer mechanism 20 and the positioning mechanism 37 repeat the above operations, a mixed pallet in which a predetermined type and number of material plate materials W are mixedly mounted on the mixed pallet 10D is generated. The material plate materials W are placed on the mixed loading pallet 10D in the reverse order to the processing order in the plate material processing machine 2 so that the earlier the processing order in the plate material processing machine 2 is loaded on the mixed loading pallet 10D. It is good to transfer.

  The generated mixed pallet is carried out of the automatic pallet placement place 15 by the carry-out conveyor 38 to the outside of the automatic warehouse 1 and further conveyed to the vicinity of the plate material processing machine 2 by the conveyance conveyor 39. Then, the loader 40 supplies the material plate material W to the plate material processing machine 2 one by one from the mixed pallet. Since the material plate material W is supplied from the mixed pallet located in the vicinity of the plate material processing machine 2 to the plate material processing machine 2, the time required to supply the material plate material W is short, and the operating rate of the plate material processing machine 2 can be improved. . As described above, when the processing order in the plate material processing machine 2 is loaded so that the earlier one is on the mixed pallet 10D, the processing is performed in the plate material processing machine 2 in the order supplied from the loader 40. Therefore, processing efficiency is good. Further, if one set of material plate material W for assembling one product on the mixed pallet is mixedly loaded, the labor for sorting the processed plate material later can be saved and the work efficiency can be improved.

  The generated mixed pallet may not be immediately taken out of the automatic warehouse 1 but may be temporarily stored in the individual shelf 5 or the like in the automatic warehouse 1. For example, when the same kind of material plate material W is continuously processed by the plate material processing machine 2, if a mixed pallet used in subsequent processing is generated and stored in advance, it will be mixed immediately when necessary. Can supply pallets.
