  2. Description of the Related Art When a plate-shaped workpiece is processed by a processing apparatus such as a laser processing machine or a turret punch press, a workpiece processing system that performs everything from storing a workpiece as a material to processing and unloading a product is employed. In the workpiece processing system, a workpiece supply device that supplies workpieces to a processing machine is arranged. The workpiece supply device loads and stores a plurality of workpieces on a pallet, and when the workpieces are supplied, the workpieces are arranged together with the pallet in the material handling unit, and supplied one by one from the uppermost workpiece to the processing device. In recent years, workpieces of different types are continuously supplied to a processing apparatus due to a reduction in production lots or the like. Conventionally, since only the same type of workpiece is loaded on the pallet on which workpieces are loaded, when supplying different types of workpieces to the processing device, the frequency of replacing the pallet increases and the stop time of the processing device increases. There was a fear. This problem can be solved if a plurality of types of workpieces corresponding to the processing order of the processing apparatus are loaded in advance on one pallet, because the time required for the pallet replacement operation can be reduced. In this case, it is necessary to prepare a mixed pallet in which different types of workpieces are loaded on the pallet.

The raising / lowering part 7a raises / lowers the shelf main body 2 (refer FIG. 1). 3A and 3B are views showing the transfer device, where FIG. 3A is a perspective view and FIG. 3B is a side view. The elevating part 7a is a pair of members formed extending in the Y direction (see FIG. 3A). Each of the pair of members is provided with a guide 7c that supports the workpiece suction portion 7b and guides it in the Y direction. The elevating part 7a supports the work suction part 7b and moves up and down integrally with the work suction part 7b. The transfer device 7 moves up and down independently of the elevator 6 described above. The elevating unit 7a moves up and down by driving a drive device (not shown) along a vertical guide (not shown) provided on the shelf body 2. The elevating part 7a moves between the storage shelves S arranged above the loader device 8 described later in the vertical direction of the shelf body 2 (see FIG. 1).

  The workpiece suction portion 7b includes a suction portion 7d that sucks the workpiece W. The workpiece suction portion 7b has a rectangular shape when viewed from above. The workpiece adsorbing portion 7b advances and retreats in the Y direction by driving of a driving device (not shown) along a guide 7c provided in the elevating portion 7a (see FIG. 3A). The workpiece suction portion 7b can advance and retreat in a direction (Y direction) approaching and separating from the shelf body 2 (see FIG. 1). The work suction portion 7b can move back and forth inside the storage shelf S. The workpiece suction part 7b can be advanced and retracted from the elevating part 7a to the material pallet storage parts 3a to 3e and the pallet P of the mixed pallet storage part 4. A plurality of suction portions 7d are provided on the lower surface side (−Z side) of the workpiece suction portion 7b. The suction part 7d is arranged over the entire lower surface of the work suction part 7b. The workpiece suction portion 7b can suck the upper surface of the workpiece W by the suction portion 7d. The suction part 7d sucks the workpiece W by vacuum or reduced pressure. The workpiece suction portion 7b can hold one workpiece W by sucking the upper surface of the workpiece W with the suction portion 7d. The suction part 7d is, for example, a suction pad. The attracting part 7d may be attracted by magnetism or the like.

  The generation of the mixed pallet PA by the transfer device 7 will be described. The generation of the mixed pallet PA by the transfer device 7 is performed under the control of the control device C. The control device C places a predetermined type of work W on the mixed pallet PA in a predetermined order based on information on the work W placed on the mixed pallet PA. The information regarding the workpiece W placed on the mixed pallet PA may be set manually by the user, or may be information generated by the control device C using the processing schedule information of the processing device M or the like.

  In the generation of the mixed pallet PA by the transfer device 7, first, the transfer device 7 takes out one workpiece W from each of the pallets P of the plurality of material pallet storage units 3 a to 3 e. At this time, first, the transfer device 7 is moved by the elevating unit 7a to the material pallet storage units 3a to 3e in which the pallet P on which the workpiece W to be taken out is stored is stored. At this time, as shown by the solid line in FIG. 1, the position of the elevating unit 7 a is set to a position where the workpiece adsorbing unit 7 b can advance and retreat above the workpiece W placed on the material pallet storage units 3 a to 3 e. Then, the workpiece | work adsorption | suction part 7b advances above the workpiece | work W mounted in the raw material pallet storage parts 3a-3e. Subsequently, the elevating part 7a is lowered so that the suction part 7d comes into contact with the upper surface of the workpiece W. Subsequently, the suction portion 7d comes into contact with the upper surface of the workpiece W. Subsequently, the workpiece W is sucked by the suction portion 7d being vacuumed or decompressed. Subsequently, the lifting unit 7a moves upward while the suction unit 7d sucks and holds the workpiece W. Subsequently, as indicated by a broken line in FIG. 1, the workpiece suction portion 7 b moves in the −Y direction, and the workpiece W attracted by the workpiece suction portion 7 b moves to the outside of the storage shelf S. As described above, one workpiece W is taken out by the transfer device 7.

  The workpiece W taken out to the transfer device 7 as described above is transferred to the mixed pallet PA. At this time, first, the elevating unit 7 a moves relative to the mixed pallet storage unit 4. The position of the elevating part 7a at this time is set to a position where the work adsorbing part 7b can be advanced and retracted above the work W placed on the mixed pallet PA, as shown by a one-dot chain line in FIG. Subsequently, the workpiece suction portion 7b advances above the workpiece W placed on the mixed pallet PA. Subsequently, the elevating part 7a is lowered so that the work W sucked by the sucking part 7d comes into contact with the upper surface of the work W placed on the mixed pallet PA. Subsequently, by releasing (releasing) the vacuum or reduced pressure by the suction part 7d, the workpiece W is released from the suction part 7d and placed on the uppermost stage of the mixed pallet PA. When the transfer device 7 places the workpiece W on the mixed pallet PA, the transfer device 7 places the workpiece W at a predetermined position. In the present embodiment, the transfer device 7 places the + Y side of the workpiece W on the mixed pallet PA with the predetermined position aligned (see FIG. 1). As a result, the + Y side position of the mixed work Wm placed on the mixed pallet PA is aligned with a predetermined position and becomes flush. In this case, since the + Y side of the mixed work Wm is aligned, the loader device 8 can efficiently carry the mixed work Wm into the processing apparatus M. By repeating the operation of taking out one workpiece W from each of the pallets P of the plurality of material pallet storage units 3a to 3e and the operation of transferring the taken out workpiece W to the mixed pallet PA, a predetermined order is obtained. A mixed pallet PA on which different types of workpieces W are placed is generated.
