Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate-shaped body such as a metal plate,
Like veneer plywood, synthetic resin plate, slate plate, etc., the plate-shaped body itself has a certain degree of rigidity, and in the course of its transportation, thin materials are simply dropped from the tip and deposited, and thick materials are supported and opened from both sides of the bottom surface. The present invention relates to a plate-shaped body depositing device that drops and deposits by doing so.

2. Description of the Related Art As a conventional apparatus for depositing seed plates,
As a deposition apparatus used for thin materials, Japanese Patent Publication No. 40-40
There is a plate material stacking device such as No. 12 paperboard, and a high speed deposition device for a plate-like body of JP-B-53-20868 is known as a deposition device used for thick materials.

[0003]

However, in the above-mentioned prior art, in the former case, when trying to deposit from a thin material to a thick material, there is no problem in the case of a thin plate-shaped body, but in the case of a thick plate-shaped body The tip of the strip itself tilts forward due to its own weight, and the tip of the strip falls obliquely and collides with the upper surface of the uppermost plate that has been deposited, which may damage the top surface of the sheet, so that it is thin. In addition, there is a problem that it is not possible to use it as a deposition device for a wide range of products from thin products to thick products because it is necessary to frequently adjust the loading speed of the plate-shaped object when it is thick, and the latter one is When a flat plate such as a thin product arrives, the central part hangs down during the transfer process by the gate bar, which prevents normal stacking operation.In any case, it covers a wide range from thin products to thick products. Can be used as a deposition device for There is a problem that does not come point.

SUMMARY OF THE INVENTION The present invention aims to solve the above problems, and a. A relay conveyor that is connected to the unloading side of the sorting conveyor and continues the transportation of the plate-shaped body to the subsequent step; b. When the plate-like body, which is disposed below the relay conveyor and is conveyed by the sorting conveyor with the tip side positioned lower than the front side on an extension line corresponding to the inclination angle of the sorting conveyor, is an open state, It is characterized by a gate bar that is activated by an intermittent drive device such as an electromagnetic clutch brake, a servomotor, and an air cylinder so that the lower surface can be supported or released each time when the product is thick. In addition, the present invention is a. A middle-held device capable of moving in and out from one side of the lifting table to the other side of the lifting table and capable of moving up and down by a predetermined height; Counting is performed each time by the sorting signal from the sorting circuit, and each time the preset value is reached, a down signal is transmitted to the lifting control circuit of the lifting table to lower the lifting table to the carry-out height and the reciprocating operation of the middle-holding device. It is characterized in that it comprises a counting circuit for transmitting a feed-out signal to the device and feeding out the middle bar.

Next, the operation of the present invention will be described. In the state shown in FIG. 1, the sorting conveyor is activated each time by the grade selection signal in the previous step and the plate detection signal from the material detector, and the sorting conveyor is sorted and conveyed to each deposition location. If the plate to be conveyed is thin, open the gate bar in advance to make it jump at a high speed from the sorting conveyor and slide on the uppermost surface of the stack plate to align the tip of the plate. When the plate-like bodies that are successively deposited so as to be brought into contact with each other and are conveyed are thick ones, the gate bar is closed in advance and the lower surface is supported so that the plates come from the sorting conveyor at high speed. The gate is opened when the plate comes to a predetermined position in front of the stopper at the tip, and after the tip of the plate just touches the stopper, the rear part falls and accumulates on the uppermost surface of the plate. It is intended to screen depositing plate-like body at a high speed by the. Further, when the plate-like objects are accumulated on the lifting table one after another and just before the plate is full, the plate-shaped objects on the lifting table are controlled by controlling the holding device and the lifting table which can be moved up and down by a predetermined height by the counting circuit. Just before the table is full, the centering device is activated to sequentially deposit the subsequent plate-shaped bodies on the centering device, and the lifting table is rapidly lowered to take out the plate-shaped body, and then the lifting table is raised. When the plate-shaped body on the middle holding device reaches a predetermined amount and stands by at a predetermined position, the middle holding device is retracted and the deposition is delivered to the elevating table so that the deposition work is performed without interruption.
