To explain this invention with reference to an embodiment shown in the drawings, an endless belt conveyor 1 includes two front shafts fixed to one front shaft 2
Rotating wheels 3, 3a and rear shafts 4, 4a divided into two parts
Two endless belts 6, 6a are stretched around two rear rotary wheels 5, 5a fixed to the rear rotary wheels 5, 5a, and each endless belt 6, 6a in the direction shown by the arrow in FIG.
, 3a to the lower ends of the rotary wheels 5, 5a.

The endless belt conveyor 1 is driven to travel intermittently or continuously. In this embodiment, a case where the endless belt conveyor 1 is driven to travel intermittently will be described below. A plurality of brackets 8, Ba are attached at approximately equal intervals and in the same phase to the two endless bands 6, 6a forming the endless band conveyor 1, and shafts 9, 9a attached to each bracket 8, Ba are attached. Attach pallets 10 to each,
Each pallet 10 is connected to the endless belt conveyor 1 by shafts 9, 9.
It is attached so that it can swing around center a.
As shown in the embodiment, each pallet 10 has a rectangular frame body or a U-shaped frame body, a support member 11 such as a bar-shaped body that forms a mounting surface for a veneer, and a support member 11 on which the veneer is placed. A ruler member 12, such as a bar-shaped member, is provided that slightly protrudes from the mounting surface to regulate the position of the side edge of the veneer at the front or rear in the direction of movement of the endless belt conveyor 1, or either one of the veneers on the mounting surface. Since the ruler member 12 regulates the position of the side edges of the veneers placed on the pallet 10 and prevents the veneers from slipping during movement, it regulates both side edges of the veneers as in the embodiment. It is also possible to restrict only one side edge of the veneer. In this case, it is more effective if the veneer mounting surface of the support member 11 is sloped downward toward the ruler member 12. be. In addition, if the positions of the ruler members 12 provided on each pallet 10 for regulating the side edges of the veneers are set at approximately equal intervals between successive pallets 10, the carrying-in means, carrying-out means, etc. described later can be simplified. At appropriate swinging ends of each pallet 10, excluding the swinging center, rollers 13, 13a are provided with rollers 14, 14a.
A guide means 1 is rotatably attached to the endless belt conveyor 1 and has a guide surface in the vicinity of the running path of the endless belt conveyor 1, which has a guide surface that is almost the same shape as the vertical circulation path of the endless belt conveyor 1.
5 is provided, and a guide means 15 for the rollers 13, 13a is provided.
By moving along the guide surface, the swinging end of each pallet 10 is supported and guided, and when the pallet 10 moves on the circulation path of the endless belt conveyor 1, the veneer placement surface by the support member 11 is always facing upward. The pallet 10 is moved so that the

In addition, in the embodiment, the guide means 15 is provided with an upper guide rail for the upper runway R of the endless belt conveyor 1, and a lower guide rail for the lower runway R'', and is connected to the rotary wheels 3, 3a. In the reversing section of the rotating wheels 5, 5a, both rails are overlapped to guide the rollers 13, 13a, but if the rollers 13, 13a are to be reversed more smoothly in the reversing section, the rollers 13, 13a are placed in the reversing section. , 13a is provided. At an appropriate position where the pallet 10 stops in the circulation path of the endless belt conveyor 1, each of the two veneers constituting the plywood is transferred to the pallet 10 in the order in which the plywood is constructed. A plurality of sets of carrying means are provided to feed and overlap the veneers so that their side edges almost match the ruler member 12, that is, one side edge or both edges of the veneers come into contact with or near the ruler member 12.

At least three or four sets of carrying means are provided depending on the number of veneers 4 constituting the plywood, but the fiber directions of adjacent veneers to be stacked are perpendicular to each other, and an odd number of veneers are used to form plywood. , and when configuring five or more plywood sheets, for example, carrying in the core veneer C in which adhesive is applied to both sides of the plywood in order from the upper side in the conveying direction of the upper running path R of the endless belt conveyor 1. A means 16 and a carrying-in means 17 for the front veneer F are arranged, and in order from the upper side in the conveying direction of the lower running path R'', a carrying-in means 18 for the center veneer Cc and a carrying-in means 1 for the back veneer B are arranged.
9 are arranged respectively. A carrying-out means 20 for sending out the stacked veneer P made by stacking these veneers from the pallet 10 and loading it onto a pile is arranged near the starting end of the lower flow path R'' on the upper side of the carrying-in means 18. Note that the arrangement positions of these carrying-in means and carrying-out means should be such that each veneer can be stacked on top of the other in the order in which the plywood is constructed, and that it can be loaded onto the pile in the order in which the plywood is constructed. The carrying-in means 17 for the front veneer F, the carrying-in means 18 for the center veneer Cc, and the carrying-in means 19 for the front veneer B carry each veneer in each pile. It takes out the fibers from piles F, CC, and B and sends them to the pallet 10, and since they have the same configuration, we will explain this with respect to the carrying means 17 for the front veneer F. F'' is the stack of the front veneers F. Mountain,
21 is an elevator for the pile F'', 22 is a take-out device equipped with a suction mechanism etc. for taking out the uppermost top veneer F of the pile F'', 23 is a conveyor such as a roller, and 24 is a sticking or suction type, etc. 25 is a stopper for regulating one end of the front veneer F.

1 taken out from the pile F'' by the taking out device 22
The front veneer F is stuck or suction conveyed via the conveyor 23 to the upper part of the pallet 10 which is stopped by the lower conveyor 24, and one end of the front veneer F is stuck to or is conveyed by suction to the top of the pallet 10 which is stopped.
When the pallet 10 reaches the position, it is released from sticking or adsorption, and is placed on the support member 11 forming the veneer placement surface of the pallet 10 so that both edges in the fiber direction substantially coincide with the ruler member 12. In this case, if the side edge of the front veneer F in the stack F'' is aligned with the ruler member 12 of the pallet 10 to be stopped, and the front veneer F is conveyed straight, the side edge will almost match the ruler member 12,
Requires equipment to correct the posture of the veneer during transportation,
The structure of the carrying means is simplified and the veneer can be accurately fed to the pallet. In addition, in the case of a rectangular veneer, in the veneer system, it is sufficient to align one side edge of the long side of the veneer with one side edge of the short side, and overlap it, and in the example, the side edge of the long side Ruler member 1 with regulation on pallet 10
2, and the side edges of the short sides are controlled by a stopper 25 provided on the carrying means, but the same effect can be achieved even if the pallet 10 is provided with a regulating member corresponding to this stopper 25. be. Also, in the other carrying-in means 18 for the center veneer Cc and the carrying-in means 19 for the back veneer B, an elevator 21 having the same structure as the carrying-in means 17 for the front veneer F is used.
, is equipped with a take-out device 22, a conveyor 23, a bottom conveyor 24, and a stopper 25, and takes out the center veneer Cc and the back veneer B one by one from each pile Cc'' and B'' and transfers them to the stopped pallet 10. Its side edge is ruler member 1
10 of each pallet by feeding them to match 2
Place it on. Carrying-in means 16 for core veneers C includes an elevator 21 that lifts and lowers a pile C'' of core veneers C similar to the above-mentioned carrying means, and lifts the core veneer C at the top of the pile C'' in the direction of its fibers. In addition to being equipped with a take-out device 22 for taking out the core veneer C and a conveyor 23 for transporting the core veneer C, there is also a gluing machine 26 consisting of a coating roll, a doctor roll, etc. that applies adhesive to both sides of the core veneer C.
, consists of a disc conveyor 27 that conveys the core veneer C coated with adhesive, a feed conveyor 28 disposed following the disc conveyor 27, etc., and the core veneer C is stopped by the feed conveyor 28. The pallet 10 is fed into the pallet 10 in such a way that the end of the pallet is aligned with the ruler member 12.

Since the disc conveyor 27 and the feed conveyor 28 transport the core veneer C coated with adhesive, these conveyors have a structure that prevents the adhesive from adhering or allows it to adhere, for example, a disc-shaped or The surface of the endless band has a structure in which convex bodies such as needles are attached, and the feed conveyor 28 does not hinder the movement of the pallet 10 and accurately feeds the end of the core veneer C in line with the ruler member 12. The analogy is structured so that it can move forward and backward. In this case as well, the side edge of the core veneer C in the fiber direction on the pile C'' is aligned with the regulated position by the stopper 25 in each of the other carrying means, and the core veneer C is transported straight. Pallet 1 so that the side edge of C in the fiber direction matches the end edge of the other veneer.
It sends it to 0. The unloading means 20 includes an elevating conveyor 29 that takes out the overlapping veneer P on the pallet 10 stopped at a predetermined position and sends it out from the circulation path of the endless belt conveyor 1;
It consists of an advance/retreat conveyor 31 that receives the overlapping veneer P from the lifting conveyor 29 and transfers it to the next conveyor 30, and a loading conveyor 32 that sends the overlapping veneer P from the conveyor 3 to the pile P'' on the elevator 21. It is something.

The lifting conveyor 29 supports the supporting member 1 of the stopped pallet 10.
It moves up and down across the gap in Figure 1 as if crossing the mounting surface, and is driven to travel intermittently, and when it stops traveling, it rises from the lower position shown by the solid line in Figure 1 to the upper position shown by the dotted line. In the meantime, take out the polymerized veneer P from the pallet 10,
When it reaches the upper position, it starts traveling and sends out the stacked veneer P to the advancing/retracting conveyor 31 which has advanced to the position indicated by the dotted line. The advancing/retracting conveyor 31 reciprocates between an advance position indicated by a dotted line for receiving the stacked veneer P from the elevating conveyor 29 and a retreat position indicated by a solid line, and transfers the stacked veneer P to the carry-out conveyor 30. The loading conveyor 32 reciprocates between the positions indicated by the solid line and the dotted line at its distal end, and the loading conveyor 32
When receiving the polymerized veneer P from the container, the end portion advances to the position shown by the dotted line, and when retreating to the position shown by the solid line, the polymerized veneer P is dropped onto the pile P'' and loaded. Starting, stopping, moving back and forth, etc. of each conveyor during stopping and running of the endless belt conveyor at a predetermined position, feeding each veneer to a pallet by each carrying-in means, and sending out a polymerized veneer from a pallet by a carrying-out means, etc. Each is equipped with a detector and a control circuit, but since automatic control thereof is commonly used in this type of single-plate mechanism device, detailed explanation will be omitted.

In addition, if the veneer mechanism is carried out while an endless belt conveyor is continuously running, the veneers may be fed into the pallet by each carrying means while conveying the veneers in the direction of movement of the pallet, and the carrying means may be Since the present invention can be easily implemented by using appropriate means such as providing a gripping body made of a polymerized veneer that moves at the same speed as the pallet, a detailed explanation of the invention will be omitted. The mechanism of each veneer to make up the plywood is, for example, when five veneers are to be assembled, as shown in diagram a in Fig. 3, the back veneer B is placed on one pallet 10 at the bottom. , the core veneer C coated with adhesive is sent in sequence by the carrying means 19 and the carrying means 16 to form a polymerized veneer P-1, and the center veneer Cc is placed in the lower position on the next pallet 10. , the core veneer C coated with adhesive is placed in the middle and the front veneer F is placed on top, and are sequentially fed in by the carrying means 18, carrying means 16, and carrying means 17 to form a polymerized veneer P-2, and then carried out. If the means 20 first loads the polymerized veneer P-1 onto the pile P'' and then loads the polymerized veneer P-2 onto the pile P'', the trowel forming a five-ply plywood sheet will be assembled on the pile P''. I can do it.

Since overlapping veneers are formed on all pallets 10 without waste, and one set of five plywood sheets is constructed by moving two pallets 10, a highly efficient veneer system can be realized. It can be done. When configuring seven plywood sheets, as shown in Figure 3b, three adjacent pallets 10 are loaded with core veneer C on top and back veneer B on each pallet 10 by each loading means. Polymerized veneer P-1 is lower, core veneer C is upper, center veneer Cc is lower, polymerized veneer P-3 is lower, front veneer F is upper, core veneer C is in the middle, and center veneer Cc is in the middle. Lower polymerized veneer P-4
If these three sets of laminated veneers are sequentially loaded onto the stacking pile P'' by the carrying means 20, seven plywood sheets can be constructed, and one set can be made by moving three pallets 10. Since it is made of plywood, it is possible to create a similarly highly efficient system.

The structure of plywood with 9 or more pieces can be implemented in the same way, and when configuring 3 pieces of plywood, see c in Figure 3.
As shown in the figure, if a stacked veneer P-5 is formed for each pallet 10, with the front veneer F at the top, the core veneer C in the middle, and the back veneer B at the bottom, one set of three veneers will be formed. Plywood can be constructed.

As described above, the present invention forms a vertical circulation path using an endless belt conveyor consisting of two endless belts, attaches a plurality of pallets to the endless belt conveyor in a swingable manner, and places a veneer on each pallet. It is equipped with a support member that forms a placement surface and a ruler member that regulates the position of the veneers, and the pallet is circulated so that the veneer placement surface always faces upward, and each veneer that is made up of plywood is placed in the circulation path. Equipped with a carrying means, each veneer composing the plywood is sequentially fed and stacked in the order of construction while the pallet is circulating, so any number of plywood can be assembled and a highly efficient system can be implemented. In addition, since each pallet is equipped with a ruler member that regulates the position of the veneers, it is possible to accurately overlap the veneers, and the position of each veneer does not shift even when the pallet is circulated. It has many advantages, such as not requiring much space, and since it uses a vertical circulation path, it does not require much land area, making it a great contribution to the plywood industry.
