DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pile device and a pile method for stacking plate materials such as cut plates and discs.

[0002]

2. Description of the Related Art FIG. 4 shows an example of a conventional plate material piler. The piler 100 feeds the sheet 102 a conveyed by the belt conveyor 101 into the piler 104 by a feed roller 103 synchronized with the belt conveyor 101. At this time, in order to align the ends of the sheet 102b, the front-rear direction is the end stop 105.
And the gauge stop 106, and the lateral direction is positioned by the side guide 107, and the floating air 108 is blown out to softly land the sheet 102b on the preceding plate 102c. At this time, a carriage 109 is provided for receiving and stacking the falling sheet 102b.

On the other hand, instead of the feed roller 103,
There is known an apparatus provided with an elevating type tapered feed roller for adjusting the entering angle of a plate material (Japanese Patent Application Laid-Open No. Sho 60-2).
No. 52556).

However, the line speed of a conveyor for transporting plate materials varies depending on conditions such as the type, material, thickness, and size of the plate material to be processed. Therefore, in the above conventional pile device, for example, when the line speed is low, the plate material falls before hitting the stopper, falls on the surface of the already stacked plate material, and the tip of the falling plate material becomes the lower plate material. Collides with the surface of the car, causing hits and scratches. In addition, when the line speed is high, the plate material hits the stopper too much and rebounds, causing problems such as breakage of the plate material itself and damage to the rear surface of the already stacked plate material. For this reason, fine adjustment according to the speed, such as fine adjustment of the height of the pillar and fine adjustment of the position of the stopper back and forth, is required.

[0005] It is an object of the present invention to ensure that stacks can be easily and reliably stacked without damaging the surfaces of the already stacked plates.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a piled sheet pile device for dropping and stacking the plate materials from the exit side of a conveyor for conveying the plate materials.
A feed roll is provided on the outlet side of the conveyor and feeds out the plate material at a constant feed speed equal to or greater than the transport speed of the conveyor. The plate material conveyed by the conveyor enters a feed roll provided on the exit side of the conveyor. The feed roll feeds the plate at a constant feed speed that is equal to or greater than the transport speed of the conveyor, so if you finely adjust the stopper and other parts according to the feed speed at the start of the operation of the device, the feed roll The entered plate materials are sequentially fed from the feed roll at a constant speed without staying on the conveyor, and are reliably and easily stacked on the already stacked plate materials without hitting, scratching or other damage.

Further, the feed speed of the feed roll is adjusted to a maximum speed of the transport speeds operated by the conveyor. By matching the feed speed of the feed roll to the maximum speed of the conveyor speed, the speed of stacking plate materials is constant even if the conveyor speed changes, so stoppers and other fine adjustment at the start of operation If you do, you can stack well.

[0008] Further, there is provided an air blowing means which is provided below the feed roll and blows air below the plate material which falls from the feed roll. By the air blowing means, the plate materials fed at a constant feed speed are supported by air pressure from below, and the already stacked plate materials are reliably stacked without damaging them.

Further, the present invention relates to a method of piled plate materials in which the plate materials are dropped and stacked from the exit side of a conveyor for transporting the plate materials, wherein the constant speed is equal to the maximum speed of the operation transport speeds at which the conveyor transports the plate materials. Is to send out the plate material. By feeding the plates at a constant speed equal to the maximum speed of the conveyor's operating transport speed, the plates are stacked at a constant feed speed without staying on the conveyor, and the surface of the already stacked plate materials is damaged. It is reliably and easily stacked without giving.
