[0002]

2. Description of the Related Art Conventionally, a stacking shelf is provided on one side of a punch press, materials are carried in from this stacking shelf by a carry-in device, and after being processed by the punch press, a large number of small products are picked up and the small products are collected. For sorting and stacking, a stacking rack is arranged on the front side table side of the punch press, and a product stacking rack provided with a cross field table and an unloader clamp is arranged on the rear side table side of the punch press.

In the apparatus constructed as described above, a punch for cutting small products is provided on the rear side table side of the punch press, the contour is cut by the punch for cutting small products, and the small products are cut off from this material. It was transferred to the cross feed table by the pipe roller of the rear side table.

Then, a pressure bar provided on the cross field table is pressed in the Y-axis direction for a predetermined amount to position it, and the positioned small products are held by an unloader clamp and accumulated at a predetermined position in a pallet on a product accumulation shelf. Was. In this case, different types of small products are arranged in the same pallet by changing their positions.

[0005]

However, in the conventional small product sorting and stacking apparatus having the above-mentioned structure, the line structure becomes long because it is provided with the material shelf, the punch press, the cross field table, and the product stacking shelf. There is a problem that it requires a large area.

An object of the present invention was proposed in view of the above-mentioned conventional problems, and it is possible to carry in a material and carry out a product in a space-saving manner, and at the same time, a small product having a simple structure and classified by type. The present invention provides a small product sorting / collecting device capable of sorting, carrying out and stacking.

[0007]

In order to solve the above-mentioned problems, the present invention accommodates a punch press, a small product cutting punch provided on one side in the vicinity of the punching position of the punch press, and a raw material. A pallet and a pallet for storing products, and either a pallet for storing materials or a pallet for storing products are selectively carried out from this stacking shelf, and the processed materials or products are stored on the rack. It comprises a carry-in / carry-out device for carrying in, a table provided between the stacking shelf and the punch press, and a transfer device for holding the cut small products and sorting and transferring them to any position on the table. It is characterized by being present.

[0008]

[Function] The material is loaded into the punch press by the loading / unloading device from the pallet storing the materials placed on the stacking rack, punching is performed at the punching position of the punch press, and a large number of small pieces are cut by the punch for cutting small products from the material. The product is separated. Then, the cut small products are held by the transfer device, accumulated at a desired position in the pallet on the table, and stored in the accumulation shelf by the carry-in / out device.

Since the small products can be sorted into desired positions on the table by product type by the transfer device, they can be sorted and stacked according to product type on the pallet of the accumulating shelf by the carry-in / out device, which is narrow. It became possible to sort and collect small products in a space.

It is possible to adsorb and hold the adsorbed small products at 3, and sort and accumulate the adsorbed small products to any position in the pallet P placed on the table 35.

Next, the operation of the above configuration will be described. First, a pallet P containing the material W is placed on the first lifter device 55 of the stacking shelf 37, and an empty pallet P for storing products is placed on the second lifter device 99 of the pallet station 43. deep. Then, the slat conveyor 4 is moved to a position where the pipe roller 53 is retracted from above the first lifter device 55.
7, the material W is adsorbed and lifted by the adsorbing and lifting device 75 from the pallet P on the first lifter device 55, and the slat conveyor 47 is rotated to adsorb and lift the device W on the pipe roller 53. By loading the material W of 75, the material W is transferred to the loading / unloading device 59. When the material W is gripped by the carry-in / carry-out clamp 71 and the carry-in / carry-out device 59 is driven toward the punch press 1 by the motor 73,
The material W rolls on the pipe roller 53 and the bearing 33 of the table 35 and is conveyed to the punch press 1.

In the punch press 1, the loaded material W is gripped by the work clamp 31, and the front side table 1
7. With the rear side table 19, the carriage base 21 is moved in the Y-axis direction, and the carriage 29 is moved in the X-axis direction to be positioned at a predetermined position for processing. In the case of multi-cavity processing, the contour of a small product is punched by a punch 10 for cutting small products.
It cuts at 7, and separates from the material W.

During this processing operation, the pallet P on the first lifter device 55 of the stacking shelf 37 is transferred to the elevator 83, and the empty pallet P on the second lifter device 99 of the pallet station 43 is It is transferred to the first lifter device 55.

The small products separated from the material W by the small product cutting punch 107 are adsorbed and taken out by the transfer device 115, rotated in a horizontal plane in a desired storage direction, and then placed on the table 35. The loading / unloading clamp 71
Hold this small product at and carry in / out device 5 by motor 73.
When 9 is driven toward the stacking shelf 37, the small product rolls on the bearing 33 and the pipe roller 53 of the table 35, and is conveyed above the first lifter device 55.

The small product pipe roller 53 is sucked and lifted by a suction lifting device 75, and the slat conveyor 4
7, the pipe roller 53 moves the first lifter device 55.
, And the small products of the suction lifting device 75 are sorted and accumulated in the empty pallet P on the first lifter device 55 according to the type of the small products.

The operation of taking out the small product from the punch 107 for cutting the small product by the transfer device 115 and the table 35.
In the transfer operation of the small product to the rotary shaft motor 1, the base shaft motor 123 and the suction tool support shaft motor 135 are driven to align the suction tool 139 in the X-axis and Y-axis directions.
This is performed while the suction tool 139 is vertically aligned by driving 29.

The small products gripped and taken out from the small product cutting punch 107 are transferred so that the small products are sorted and accumulated in the empty pallet P on the first lifter device 55 for each type. The device 115 is rotated in a horizontal plane in a desired storage direction and then placed on the table 35. The small product gripped and taken out this time is different from the small product previously gripped and taken out. In this case, after this removal, the suction tool 139 is moved to Y by driving the base shaft motor 123 and the suction tool support shaft motor 135 as described above.
By largely aligning in the axial direction and also aligning in the X-axis direction, the small product previously gripped and taken out is positioned at another position on the table 35. To change the left and right sides of a small product by 180 °,
The suction tool support shaft motor 135 may be driven to rotate the suction tool 139 by 180 °.

Further, at the time of transfer from the transfer device 115 to the first lifter device 55, the motor 7 of the carry-in / out device 59.
By adjusting the drive amount of No. 3 and changing the stop position of the loading / unloading clamp 71 with respect to the first lifter device 55, small products are classified in the empty pallet P on the first lifter device 55 by the X-axis. Can be sorted according to direction and accumulated.

[0036]

As described above, according to the sorting and stacking apparatus for small products of the present invention, it is possible to sort each product type into a desired position on the table by the transfer device. In addition, it is possible to sort and collect products according to product type, which enables small products to be sorted and collected in a small space.
