Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work unloading / collecting device for pulling out products processed by a plate processing machine from the plate processing machine and carrying them out and stacking them on a stacking pallet of a stacking device.

[0002]

2. Description of the Related Art Conventionally, the following two methods are well known as a work unloading and accumulating means for extracting a product processed by a plate processing machine from the plate processing machine and carrying it out and accumulating it on an accumulating pallet of an accumulating device. There is.

(A). For products processed with a plate processing machine, the vertically movable suction pad lowers to adsorb the product, then raises the suction pad and moves it above the accumulation pallet of the accumulator, and then lowers the suction pad. Products are accumulated on the accumulation pallet.

(B). The product processed by the plate processing machine is clamped by the carry-out clamp, and then the carry-out clamp can be carried out to the slat conveyor of the stacking device. Then, when the slat conveyor is rotated and rotated, the upper part of the accumulating pallet is released, and the product is accumulated on the accumulating pallet by unclamping the discharge clamp.

[0005]

By the way, of the above-mentioned conventional work unloading and accumulating means (A), since the product is conveyed in the air while the product is adsorbed by the adsorption pad, the conveyance weight is limited. At the same time, the frame and the suction portion need to have strength, which increases the cost. In addition, the size of the product is limited, and when the product size is increased, the suction portion also becomes large, and further, the transport weight increases and the cost increases.

According to the method (B), when the transport clamp is unclamped from the product above the stacking pallet, that is, when the stacking stack receives a considerable load and impact, a considerable strength is required, which is a problem. .

It is an object of the present invention to provide a work unloading and stacking device which facilitates unloading from a light weight product (minimum work) to a heavy weight product (maximum work) and allows smooth stacking at the time of stacking. To do.

[0008]

In order to achieve the above object, a work unloading and stacking device of the invention according to claim 1 is a product unloading device capable of moving in the product unloading direction to the same height position as a table in a plate material processing machine. And a stacking device is provided adjacent to the product unloading device, and the product supporting device is movably installed at the stacking device at substantially the same height as the product unloading device. Is provided with a stacking pallet for stacking, and product suction means capable of moving up and down between the product unloading means and the stacking pallet.

The work unloading and accumulating device of the invention according to claim 2 is characterized in that the product unloading means comprises a loader capable of moving in the product unloading direction, and a product suction means below the loader. Is.

In the work unloading and stacking apparatus of the invention according to claim 3, the product supporting means is composed of a plurality of support rollers for supporting the products and a conveyor capable of moving the support rollers above the stacking pallet. It is characterized by that.

[0011]

With the above-described work unloading and stacking device according to the first aspect, the product processed by the plate processing machine is carried out by the product unloading means to the product supporting means of the stacking device. The product carried out to the product supporting means is adsorbed by the product adsorbing means when the product adsorbing means descends. The product is smoothly accumulated on the accumulation pallet by retracting the product support means and lowering the product suction means. Further, the product carried out from the plate material processing machine to the product supporting means is carried out while being supported at the same height position. Therefore, products of a light weight product (minimum work) to products of a heavy weight product (maximum work) can be easily carried out, and the carried-out products can be smoothly accumulated without any impact.

By using the work unloading and stacking device of the invention according to claim 2, the product unloading means is provided with a loader capable of moving in the product unloading direction and a product adsorbing means under the loader. It is carried out while being stably supported from the processing machine to the stacking device.

According to the work unloading and stacking device of the present invention, the product supporting means is composed of a plurality of support rollers for supporting the products and a conveyor which is capable of moving the support rollers above the stacking pallet. From the above, the product whose support roller is retracted is positioned above the accumulating pallet. Thus, the products are accumulated on the accumulation pallet.

With the above structure, when the drive motor 73 is driven, the sprocket 67 is rotated via the sprockets 75 and 71. Further, the rotation of the sprocket 67 causes the sprocket 65 to rotate via the chain 69. Since the sprockets 57 and 53 are rotated by the rotation of the sprockets 67 and 65, the suction frame 79 is moved up and down via the chains 63 and 61, so that the suction pad 81 and the suction magnet 83 are also moved up and down.

The operation of carrying out the product G punched by the turret punch press 1 and stacking the product G on the stacking pallet 39 of the stacking device 9 in the above configuration will be described.

The product G punched by the turret punch press 1 is placed on the table 5. In this state, the slide 17 is moved to the left side in FIG. 1 and stopped at the position indicated by the solid line. When the suction pad 23 is operated, the product G is sucked by the suction pad 23.

In this state, the slide 17 is moved to the right in FIG. 1 and stopped at the position indicated by the chain double-dashed line.
At this time, the product G slips from the table 5 and the carry-out table 13 without floating, and is carried onto the support roller 33 of the slat conveyor 25.

Then, when the operation of the suction pad 23 is turned off, the product G is detached from the suction pad 23 and placed on the support roller 33. And the slat conveyor 2
When the chain 31 of No. 5 is rotated clockwise, the product G becomes the support roller 4 of the slat conveyor 41.
9 is carried out.

Next, by driving the drive motor 73, the suction frame 79 is lowered to move the suction pad 81.
Alternatively, the product G is attracted by the attraction magnet 83. The drive sprocket 43 is rotated to support the support roller 49.
Is rotated and the left and right driven sprockets 45 are released. Then, the suction frame 79 is lowered to place the product G on the stacking pallet 39 and the suction pad 8
1 or the attraction magnet 83 is turned off, and the product G is separated from the attraction pad 81 or the attraction magnet 83 and accumulated on the accumulation pallet 39.

The product punched in this way is
From the table 5 to the slat conveyor 41, they are supported at the same height position and are carried out without being transported in the air, so that they can be smoothly accumulated. Therefore, regardless of the size of the product, it is possible to easily carry out from the minimum work to the maximum work.

Further, the support roller 49 is retracted from the horizontal state from the slat conveyor 41 to the accumulating pallet 39, and the product G is accumulated on the accumulating pallet 39 without being impacted by the lowering of the suction frame 79. You can
