Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for stacking delivered plates.

When manufacturing plywood from veneer, the veneer is fed in the direction of the arrow from between the upper and lower gluing rollers installed on the gluing machine (not shown) on the left outside of frame 1 on the left side of Figure 1, facing frame 1. It is guided by a large number of rollers (not shown) between frame 2 and frame 1, which were built at a required distance (mainly the width of the veneer), and is received by a worker waiting on the outside left of frame 2. The veneers are sandwiched between the veneers supplied by a worker who handles unglued veneers on the left outside of the frame 2, and are laminated and pressed to form plywood. In this case, handling the glued veneer requires hard labor in addition to applying glue. This invention relates to a plate stacking device that automates the process of stacking plate bodies such as veneer, plywood, or gypsum boards, thereby saving manpower. As shown in FIG. 1, the means for achieving this automation is to adjust the distance D and the distance H between the upper and lower rollers 3 and 4 for feeding the veneer, which are provided on the upper part of the frame 1. By feeding out the veneer a while holding it in a pinched manner to the end and holding it so that it does not fall until it travels and reaches the stopper plate 15, the guide that is conventionally provided between the frames 1 and 2 is removed. The roller is omitted, and the front end of the veneer a is attached to the frame 2.
When reaching this point, the lower roller 4 is pulled toward the frame 1 to drop the veneer a between the frames 1 and 2. At the same time, by rotating the veneer receiving device provided on the frame 2 side when the front end of the veneer a is received, the veneer a is pushed back to align and overlap. By doing this, the work of receiving glued veneers when manufacturing plywood is automated, and veneers to which glue is not attached are replenished before and after the dropping of the veneer a, thereby forming plywood.

To explain the above embodiment, the frames 1 and 2 are formed in a gate shape and are connected by a 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. At the top of both sides of the frame 1 are upper rollers 3 that are longer than the length of the veneer a.
Both ends are bearings. An arm 8 is protruded from a base 7 which is supported by bearings on both sides of the frame 1 below the upper roller 3, and an arm 8 corresponding to the lower roller 4 is loosely supported between the front ends of the arm 8. That is, as shown in FIG.
A large number of disks 10 are mounted on the same shaft 9. This disc 10 prevents the glue attached to the veneer a from being transferred to the long axis 9, thereby preventing the disadvantage of the conventional lower roller 4 having a cylindrical shape that causes the glue to transfer. As shown in FIG.
The length of the arm 8 and the position of the base 7 at one end of the arm 8 are selected so that the distance H between the opposing outer peripheral surfaces of the lower roller 4 has the following relationship. In other words, the distances D and H are such that when the veneer a is fed out into the horizontal space, it bends downward from the front end due to its own weight, and the upper and lower rollers 3 and 4 hold the veneer a in a pinched manner. Stopper plate 15
The vertical distance H and the front-to-back distance D required to reach the above are selected. Next, lower roller 4
Telescopic rods of air cylinders 11 provided on both outsides of the frame 1 are attached to both ends of the long axis 9 of the frame 1, and the lower ends of the cylinders 11 are loosely attached to the frame 1. Therefore, the air cylinder 11 causes the lower roller 4 to rotate vertically about the base 7 as a fulcrum. The upper and lower rollers 3 and 4 are rotated in the feeding direction of the veneer a via chain wheels 13 and 14, the foil of the upper roller 3, and the foil of the base 7, which are rotated by the drive of the electric motor 12.

Next, attach the long shafts 16 with L-shaped stopper plates 15 protruding from the upper sides of the frame 2 to the frame 2.
The telescopic rod of an air cylinder 17, which is also provided inside the frame 2 and is supported on the inside of the frame 2, is attached to the long shaft 16, and the stopper plate 15 is rotated around the long shaft 16 by the cylinder 17. There is. Note that a fixed wood board 18 is provided close to the opposing inner sides of the frames 1 and 2 to guide the alignment and stacking of the veneers a.

According to the above configuration, the glued veneer a held by the upper and lower rollers 3 and 4 provided at intervals D and H and fed out reaches the stopper before the front end curves downward and hangs down due to the feeding speed. Board 1
It is accepted in 5. The air cylinders 17 and 11 are activated by a known electric detector installed on the stopper 15 to detect the collision of the single plate a, and the L-shaped stopper plate 15 is rotated downward, and the lower roller 4 is moved downward. As the glued veneer a loses its support, it falls. At this time, the L-shaped stopper plate 15 pushes back the veneer a in the opposite direction, and the lumber board 18 guides it. Before and after the dropping, the original plywood plates are laminated by supplying non-adhesive veneers between the fixed wooden boards 18 using a separate method.

In this way, the present invention allows the axes of the conventional upper and lower rollers to be aligned along a straight line by means of holding the veneer using the upper and lower rollers 3 and 4, which are arranged at intervals D and H when the veneer is fed out. The degree of curvature of the veneer is smaller than that of the conventional one, and combined with the feeding speed, it eliminates the need for the conventional guide roller support.
Moreover, it has the feature of guiding the fall and aligning and superimposing it.
