Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a multi-row work in which a work processed by a plate material is conveyed by a plate processing machine and a predetermined number of the work is stacked in a multi-row on an accumulating trolley. The present invention relates to an integration method and an apparatus therefor.

(Prior Art) Conventionally, a work cut to a certain length by, for example, a shearing machine as a plate material processing machine is collected by a conveyor of a transport device provided behind the shearing machine and provided adjacent to the transport device. It is generally known that a predetermined number of sheets are stacked on a stacking table of a cart, and then the next work is sequentially stacked in multiple rows next to the stacked works.

(Means to be Solved by the Invention) By the way, the means for stacking the work, which has been processed by the plate material, in multiple rows on the pallet mounted on the stacking table in the above-described stacking cart of the prior art is first provided on one side of the stacking table. A fixed number of workpieces conveyed to the fixed stoppers are erected, and a certain number of the workpieces are accumulated on the pallet.Then, the next work is abutted against the accumulated workpieces and a certain number of the workpieces are accumulated. ing.

Therefore, one end of the first accumulation work to be accumulated on the pallet placed on the accumulation table is in close contact with the fixed stopper, and one end of the next accumulation work to be accumulated is the other end of the already accumulated accumulation work. It is integrated in close contact with. Therefore, when transporting the accumulated work to the next process, for example, a machine such as a turret punch press, to another place, when binding the accumulated work on the pallet with packing tape so as not to collapse, the accumulated work Must be lifted with a forklift to leave a slight gap between the accumulated works, and then tied up with packing tape, which is troublesome and labor-intensive.

SUMMARY OF THE INVENTION It is an object of the present invention to improve the above-mentioned problems, when stacking works in a stacking table in a stacking cart in a multi-row manner, by providing a small gap between the stacked works and stacking the works, It is an object of the present invention to provide a multi-row stacking method of work and an apparatus therefor, in which the work can be easily tied up and the labor and labor for packing are not required.

(Means for Solving the Problems) In order to achieve the above object, according to the present invention, a fixed stopper erected on one side wall of an accumulating table that can move up and down and back and forth is set to a desired length in advance. In the state where the stacking table is positioned at a desired height and the stacking table is positioned at a desired height, the first workpieces processed with the plate material are stacked one by one on the stacking table while the stacking table is lowered, and the stacking table is lowered. Then, after accumulating a certain number of sheets,
Moving the stacking table in the same direction as the transport direction of the first processed plate material by a distance slightly longer than the width of the work and raising the stacking table to a desired height position;
Next, the stacking table is moved in the direction opposite to the work conveying direction, and after the first work already stacked on the stacking table for a fixed number of pieces abuts against the partition plate, the next second work is stacked on the fixed number of sheets, This is a multi-row integration method for a work, characterized in that the workpieces are sequentially stacked in multiple rows.

In addition, the present invention provides a transfer device for transferring a workpiece on which a plate material has been processed, a stacking truck having a vertically movable and vertically movable stacking table provided adjacent to the transfer device, and a stacking truck in the stacking truck. A multi-row of work comprising: a fixed stopper erected on one side of a table; and a partition plate provided on the transfer device and movable back and forth and abutting against the fixed stopper or the side of the integrated work. An integrated device was constructed.

(Effect) By adopting the multi-row stacking method and the apparatus of the present invention, the fixed stopper erected on one side wall of the stacking table in the stacking cart that can move up and down and back and forth can have a desired length in advance. And a stacking table is positioned at a desired height position.

In this state, the first workpieces processed by the plate material are transported by a transport device provided adjacent to the stacking trolley, and are stacked one by one on a pallet placed on the stacking table while abutting against the partition plate. And the accumulation table is lowered. Thus, a fixed number of the first works are stacked on the stacking table.

Next, the stacking table of the stacking cart is moved in the same direction as the transport direction of the first work by a distance slightly longer than the width of the work, and the stacking table is raised to a desired height position. After that, the stacking table is moved in the direction opposite to the conveying direction of the work, and after the first work already stacked on the stacking table by a fixed number is abutted against the partition plate, the next second work is stacked on a fixed number. To

Then, by repeating this process sequentially, the workpieces are accumulated in multiple rows on the accumulation table. After that, a gap of the width of the partition plate is provided between the workpieces stacked in multiple rows, so the packing tape can be easily inserted into this gap, so the packing tape can be inserted without any effort and labor. The accumulated work is bound.

By repeating this process for a fixed number of sheets, as shown in FIG.
Are accumulated on the pallet P in a fixed number. Each time one work W is stacked on the pallet P, the lifter 109 is automatically lowered by the thickness of the work W.

When a certain number of works W are accumulated on the pallet P, the lifter 109 is further automatically lowered, and as shown in FIG. 8 (C), the partition plate 65 is moved past the uppermost work W by the photoelectric sensor 101. Is detected.

Next, the stacking cart 5 is automatically driven in a direction away from the transfer device 3 (rearward direction) by driving the servo motor 113,
The width d + α (constant) of the work W is detected by the encoder 115 and stopped in the state shown in FIG.

When the accumulation cart 5 is stopped, the lifter 109 is automatically raised, and when the position of the pallet P is detected by the photoelectric sensor 101, the lifter 109 is stopped as shown in FIG. 8 (E).

The positioning of the lifter 109 is completed by abutting on the right side surface of the plate 65.

When the positioning of the lifter 109 is completed, as shown in FIG.
Is conveyed by the belt conveyor 23, and a predetermined number of sheets are stacked on the pallet P while being in contact with the work W in the first row and abutting against the partition plate 65 so as not to be damaged.

Thereafter, by repeating the steps from FIG. 8 (C) to FIG. 8 (G), multi-row integration from the third row is performed, and FIG. 8 (H) shows the third row. The state where the works W are accumulated is shown.

As described above, when the work W on which the plate material is processed is stacked in multiple rows on the pallet P placed on the stacking table 125 of the stacking trolley 5, the partition plate 65 abuts against the fixed stopper 133, and each work W Are stacked while being abutted against the partition plate 65, so that each work W is collected on the pallet P in a state of being separated by a gap corresponding to the width of the partition plate 65, so that the load does not collapse during transportation in a subsequent process. As described above, the packing tape can be easily inserted into the gap, and each integrated work W can be bound without any trouble and effort.

The present invention is not limited to the above-described embodiment, but can be embodied in other modes by making appropriate changes. In the present embodiment, an example is described in which a shearing machine is used as a plate material processing machine, but other machines can also be used.
