Abstract

PURPOSE:To automate the stacking of veneers, by providing an upper and a lower rollers at the end of a veneer send-out passage so that the rollers can pinch-hold the veneer without letting it sag and by using the rollers to send out the veneer in a cantilever state and by causing a stopper plate to receive the front edge of the veneer. CONSTITUTION:A lift 6 is provided between gate-shaped frames 1, 2 so that the lift can be moved up and down. An upper roller 3 is supported on the upper part of the frame 1. An arm 8 is supported at 7 on the frame 1 under the upper roller 3 so that the arm can be swung. A lower roller 4 is supported on the free end of the arm 8. The length of the arm 8 and the position of the supported part 7 are set so that the lower roller 4 is located with distances D, H relative to the upper roller 3. These rollers 3, 4 are rotated together by an electric motor 12 through chains. The arm 8 is swung by a cylinder 11. A stopper plate 15, which is swung by a cylinder 17, is provided on the upper part of the frame 2 so that the plate can receive the front edge of a veneer (a).

Description

DETAILED DESCRIPTION OF THE INVENTION This issue is related to the stacking device for the veneers sent out.

When manufacturing a complete anvil from a veneer, the veneer fed in the direction of the arrow from between the rollers on the top and bottom is attached to the gluing machine provided on the left outside of the frame l on the left side of Figure 1. Frame 2 and Frame L were built opposite Frame 1 at a required distance (mainly 11+111 of veneer).
7 Guided by the rollers of f17J (not shown), the receiver is stopped by the 2N waiting on the left outside of frame 2, and is sandwiched between the veneers supplied by the worker who handles unglued veneers on the left outside of frame 2. It is then laminated and pressed to form plywood. In this case, gluing is hard labor in addition to covering the veneer with glue. This invention 1? , which saves manpower by automating the work, is characterized by automating the work of stacking not only veneers but also plate-like objects as described above. The means for producing this feature is as shown in FIG. By feeding υ while holding the veneer a in a pinched manner up to g and ′#I, and by keeping the veneer a from falling until it reaches the frame 2 in accordance with the traveling speed of the veneer a, the frame 1 .The guide roller conventionally provided between frames 1 and 2 is omitted, and when the front end of the veneer a reaches the frame 2, the lower roller 4 is pulled toward the frame ] side, thereby increasing the distance between the frames 1 and 2. Pressure is applied so that the veneer a is dropped. At the same time, the veneer a receiving device C provided on the frame 2 side is rotated when the front end of the veneer a is stopped.
is pushed back to achieve complete overlapping. When plywood is produced by applying pressure in this manner, the production sheet for the glued veneer receiver is automated, and the veneers without glue are replenished before and after the veneer a is dropped, thereby forming plywood.

To explain the above-mentioned practical example, the frame 1.2 is formed in the shape of a gate and is connected to the bottom frame 5 at the lower end. A lift 6 is provided between the frames 1 and 2. When the number of stacked veneers reaches a certain height, the lift 6 automatically lowers by that height, and such a lift 6 is known. Both ends of the upper mesh 3, which is longer than the length of the veneer a, are supported by bearings on both upper sides of the frame l. Furthermore, an arm 8 is provided protruding from a base 7 which is supported by bearings on both sides of the melem 10 below the cola 3, and between the front ends of the arm 8, something corresponding to the lower roller 4 is loosely received. That is, as shown in FIG. 2, a long shaft 9 is supported between arms 8, and a large number of discs IO are mounted on the same shaft 9.The disc 10 allows the length of the glue φ11j9 to be attached to the veneer a. This prevents the adhesive from transferring to the cylindrical shape of the conventional lower roller-4.
As shown in FIG. 1, the length of the arm 8 and the position 1?'C of the base 1i117 of one end of the arm 8 are selected so that the distance and H relationship between the arm 8 and the upper roller 8 are as shown in FIG. The interval 'flAD,H is as described on the ULI day, but when the veneer a is sent out into the horizontal air 11tl, its white breath causes it to move downward from the previous y)°ml. The bending part is held in a pinched manner by the upper and lower rollers 8.4+, and combined with the feeding speed of the veneer a, the veneer a
Up and down and front and back FM necessary to maintain up to the end of the train
is selected. Next, the telescopic rods of the air cylinders 11 provided on both outsides of the frame 10 are attached to both ends of the length 6119 of the four rollers.

The stopper 47715 is rotated by [attached to the same cylinder] 7 with the shaft 16 as a fulcrum. In addition, according to the above-mentioned structure Ha in which a complete piece of veneer a (a fixed wooden board for guiding the tatami mat) 8 is provided close to the inner side facing the frame 1 and the frame 2', there is a gap 1 between the upper and lower rollers 3.4. The veneer a held by $D and H is fed out at a feeding speed U[1] and is received by the stopper plate 15 before its front end curves downward and hangs down. The air cylinders 17 and 11 are actuated by a well-known air relay that senses the full sleeve length of the single plate a provided on the plate 15, and the L-shaped stopper plate 15 is rotated downward. As it rotates downward, the glued veneer a loses its support and falls. At that time, the L-shaped stopper plate 15 pushes the veneer a back in the backward direction, and the lumber board 18 pushes it back. The original plywood plates are laminated by supplying the veneer, which does not have adhesive, to the space between the fixed wood boards 18 by a separate method before and after falling.

In this way, the present invention reduces the curvature of the veneer by adjusting the interval when feeding the veneer, and by holding the veneer by means of H, compared to the case where the shafts of the upper and lower rollers of the veneer are opposed to each other. The reduced strength, combined with the feeding speed, makes it difficult for American guide rollers to catch the material, and it also has the advantage of guiding the fall and stacking.
