Description

  The present invention relates to a plywood extracting device for extracting defective products including scratches and the like from a bundle in which a plurality of plywoods are stacked, and a plywood alignment device for aligning a plurality of stacked plywoods vertically and horizontally.

  Plywood is usually stacked and packed in units of 100 or 70 sheets and transported. Such plywood may be damaged in the course of packing and transportation, and such plywood is extracted as a defective product. Conventionally, unpacking plywood is done by unpacking and marking defective products with scratches etc. from the stacked plywood bundle, manually removing non-defective products, removing defective products, and again It was done by repeating the work of reloading based on good products. However, the work of extracting defective products from such heavy plywood stacked by as many as 100 sheets by repeating such manual work is extremely heavy labor and requires a very long time for the work. Furthermore, there is a possibility that extra defective products may be generated during the transportation due to the manual transportation of heavy plywood.

  In addition, since the number of the plywood is reduced by the removal, the package must be reassembled and packed in a prescribed unit of 100 or 70 sheets. Such repeated plywood stacking tends to cause the laminated plywood to be in a state in which the length and width of the plywood are shifted. Conventionally, such a shift in the plywood has been corrected by hand. However, such adjustment of the displacement is a very labor-intensive and time-consuming operation in the case of a bundle of heavy laminated plywood as in the case of the above-described extraction operation.

  An object of the present invention is to solve the above-described problem, and an object of the present invention is to provide a plywood extracting device that can easily extract defective products from a bundle of plywood in a short time with a small amount of labor. Another object of the present invention is to provide a plywood alignment that can easily and easily align the front, rear, left, and right edges of a bundle of a plurality of laminated plywood having irregularities in front, rear, left, and right with little labor. It is to provide a device.

A pair of engaging wheels rotatably mounted, and a pair of mounting claws of a vehicle with a lift on the pair of engaging wheels in a state where the first flat plate portion is placed on the floor surface. The second flat plate portion is placed on the floor through an inclined state by the engagement by inserting the portion, the movement of the vehicle with the lift, and the lowering of the mounting claw portion.

  In the device configured as described above, the plywood extracting device is placed on the first flat plate portion by placing the first flat plate portion on the floor surface, and further transporting a bundle of a plurality of plywood by a lift or the like and loading the bundle on the first flat plate portion. Then, a pair of mounting claws of the vehicle with a lift are inserted into and engaged with the pair of engagement rings of the second flat plate portion, and the vehicle is moved to pull the plywood extracting device and lower the mounting claws. The second flat plate portion is smoothly placed on the ground while the plywood extracting device is inclined. Thus, the plurality of plywood stacked on the first flat plate portion is placed laterally on the second flat plate portion, and at least a part of the plywood bundle is easily held on the vertical member side. Therefore, the defective product of the plywood located in the middle of the bundle of the plywood can be smoothly taken out without extracting another good product. As a result, according to the present invention, the labor for extracting defective products is significantly reduced as compared with the related art, and the operation time is greatly reduced. Further, according to the present invention, in the process of extracting defective products, there is almost no need to move other good products by applying force, and thus there is almost no possibility that a new defective product will be generated in the extracting process. Therefore, an increase in cost due to occurrence of a new defective product can be suppressed.

It is inserted between the spacing plates. Furthermore, since the bundle of plywood is pressed against the positioning member vertically erected on the horizontal table at one end in the width direction of the horizontal table by the vehicle with the lift, the front and rear unevenness is corrected, and the plywood is stacked on the horizontal table. You. In this manner, the lateral displacement of the plywood is immediately corrected by the pair of spacing plates, and the longitudinal displacement of the plywood is immediately corrected by being pressed against the positioning member. Therefore, the displacement of the plywood in the lateral direction and the front-back direction can be corrected in a very short time without requiring any manual operation. As a result, according to the present invention, the burden of the operation of trimming the laminated plywood in the lateral direction and the front-back direction is greatly reduced, and the operation time is greatly reduced.

  Further, in the third feature, one of the pair of space holding plate portions can be movable in the longitudinal direction of the horizontal base. Thereby, since the interval between the interval holding plate portions of the plywood aligning device can be adjusted, it is possible to easily cope with a change in the dimensions of the plywood.
