BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for stacking plate materials for stacking plate materials sequentially fed from a transport system.

[0002]

2. Description of the Related Art A stacking apparatus for sequentially feeding and stacking sheet materials such as sheets which are conveyed one by one in a substantially horizontal direction via a conveying system and accumulating them is widely used. This type of stacking device is configured such that the plate materials sequentially fed are stacked on a stacking table such as a dedicated pallet or a dedicated skid arranged in the stacking unit.

[0003] By the way, on the above-mentioned stacking table, a plate material of a fixed size is always stacked at a predetermined position. Therefore, when changing the stacking position on the stacking table, it is necessary to manually move the plate material to a desired position after the plate materials are stacked on the stacking table. on the other hand,
When changing the size of the plate material, an operation of stacking different size plate materials on a stacking table and then transferring the different size plate material to a dedicated stacking table is performed.

[0004]

However, as described above, once the plate materials are accumulated on the stacking table, the plate material is moved to a desired position or moved to a dedicated stacking table. Therefore, it has been pointed out that the entire operation is considerably complicated. In particular, recently, with the diversification of products, there has been an increasing demand for collecting plate materials of various different sizes at arbitrary positions on a stacking table. In this case, the above-described method has a problem that the number of workers needs to be increased, and work efficiency and automation are not performed.

The present invention solves this kind of problem and provides a method and an apparatus for stacking plate materials that can easily stack plate materials of arbitrary dimensions at arbitrary positions on an accumulation table. With the goal.

[0006]

In order to solve the above-mentioned problems, in the method and apparatus for stacking plate materials according to the present invention, first, the stacking table is moved vertically with respect to the transport system, the direction in which the plate materials are charged, and It is selectively moved and positioned in the width direction crossing the loading direction. Next, the plate material is fed from the transport system, so that the plate material can be stacked at an arbitrary position on the stacking table.

A height positioning mechanism for vertically positioning the stacking table with respect to the transport system includes an elevating means for raising and lowering the stacking table, and a height detecting means for detecting the height of the stacking table. . Therefore, the stacking table can be automatically and accurately positioned in the up-down direction with respect to the transport system.

Plates of any size can be stacked at any position on the stacking table. Here, the tip positioning section includes tip pressing means for pressing the tip of the stacking table, and moving means for moving the tip pressing means forward and backward with respect to the tip. For this reason,
It is possible to reliably position the stacking table in the feeding direction of the plate material with respect to the transport system.

In addition, the leading end pressing means has a leading end stopper which comes into contact with the leading end of the plate material in the feeding direction to regulate the leading end position of the plate material, while the rear end positioning portion regulates the rear end position of the plate material. A rear end stopper for regulating a rear end position of the stacking table is provided. Therefore, positioning of the stacking table and positioning of the plate material can be easily performed with a simple configuration.

Further, the distal end positioning section includes elevating means for raising and lowering the distal end pressing means and the distal end stopper, and locking means for holding the distal end pressing means and the distal end stopper at a predetermined height position. Thus, the tip pressing means and the tip stopper do not needlessly change the height position, and the tip pressing means and the tip stopper can be effectively held at the predetermined height position.

A second positioning mechanism for positioning the stacking table in a width direction intersecting the loading direction; first and second side pressing means for pressing both sides of the stacking table intersecting the loading direction; First and second moving means for individually moving the first and second side pressing means with respect to the both sides, respectively. For this reason, the stacking table is accurately and smoothly positioned at an arbitrary position in the width direction with respect to the transport system.

[0012] Further, the second positioning mechanism regulates first and second side stoppers for regulating both side positions intersecting the plate material input direction and regulating both side positions of the stacking table, and first and second side stoppers. Side pressing means and said first and second
First and second side lifting / lowering means for integrally lifting / lowering the side stopper are provided. Thereby, the stacking table and the plate material are accurately positioned in the width direction, and the configuration is simplified.

It is possible to cope with the case where the dimensions are different. Therefore, compared with a conventional device in which only plate materials of a certain size are stacked at a certain position on a special pallet (or a special skid), various different plate materials 14 can be stacked at an arbitrary position on the pallet 16, The effect is obtained that the efficiency and automation of the accumulation work are easily performed.

Although the present embodiment has been described using the pallet 16 as the stacking platform, various stacking platforms such as skids can be adopted as long as the plate members 14 can be stacked.

[0066]

As described above, in the method and apparatus for stacking plate materials according to the present invention, the stacking table is selectively provided in the vertical direction with respect to the transport system, the direction in which the plate material is inserted, and the width direction intersecting the input direction. By moving, the plate members can be stacked at an arbitrary position on the stacking table. This eliminates the need for manual transfer of plate materials on the stacking table, and facilitates the efficiency and automation of the entire stacking operation.
