Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a plate-shaped object receiving and stacking mechanism that receives and deposits plate-shaped objects that are sequentially sent out.

(Prior art and its problems) When manufacturing plywood, etc., glued veneers and structural veneers with the same texture on the front and back are stacked and piled up alternately.
Once a certain number of sheets have been stacked, they are transported to a multi-stage hot press, where one set is placed in each stage and bonded under heat and pressure to form plywood.

Conventionally, during this process, the overlapping loading of glued veneers and other constituent veneers was carried out by a worker who supplied the middle veneers one by one to the spreader, and a worker who was placed near the receiver to receive the glued veneers coming out of the spreader. The work is carried out entirely by hand, with two workers on the left and right carrying the veneer to the stacker, and two workers on the left and right taking turns to carry the other component boards, such as the front and back, which have been stacked separately, onto the stacker. . However, such manual work is not only inefficient but also expensive, and requires skilled technique and effort as the edges of each veneer must be precisely aligned and overlapped. It is said that

(Object of the invention) In order to eliminate such drawbacks, the present invention aims to provide a plate-like object receiving and stacking mechanism suitable for automating the work of receiving and stacking glued veneers.

(Structure of the invention) The plate-like object receiving and stacking mechanism according to the present invention includes a plate-like object supplying means that sequentially sends out the plate-like objects, a veneer receiving shelf that moves horizontally forward and backward, and a veneer receiving shelf that moves on the veneer receiving shelf. A plate-shaped object receiving means consisting of a pressing plate that moves relatively forward and backward in the horizontal direction is disposed oppositely above the stacker on which the plate-shaped objects are deposited, and the plate-shaped object receiving means is configured to receive the plate-shaped objects sent out from the plate-shaped object supplying means. After receiving the veneer on the veneer receiving shelf of the means, the veneer on the receiving shelf is pressed against the ruler plate installed on one side of the stacker by moving the veneer receiving shelf backward and moving the pressing plate forward. The stacker is configured to fall and deposit on the stacker while regulating its position.

(Example) The illustrated device is a 3-ply plywood stacking device that adopts the plate-like material receiving and stacking mechanism according to the present invention, and glues middle ply veneers on the left and right with the veneer loading mechanism part A in the center. Mechanism part B, front and back veneer structure Mechanism part C
It consists of

The veneer loading mechanism section A includes a veneer receiving shelf 10 that can be driven forward and backward in the horizontal direction, a pressing plate 11 that pushes down the veneers on the receiving shelf 10, and a front edge of the veneer to be pressed. It is composed of a stacker 21 having a ruler plate 20 in contact with it. The veneer receiving shelf 10 is designed to reduce the amount of adhesive removed.
It is formed by a fork-shaped shelf frame. Also,
The receiving shelf 10 is configured to be movable forward and backward in the same direction as the veneer feeding direction. Referring to FIG. 3, the advancing/retracting drive mechanism is constructed by equipping a pinion 13 at the tip of a drive cylinder 12, and meshing the pinion with a rack 14 having a receiving shelf 10 formed on the lower surface of the base frame. . With this mechanism, the receiving shelf 10 has a pinion 13 and a roller 15.
You will now be able to travel between. Furthermore, pinion 13
is a rack 18 formed on a fixed frame 17 with a small-diameter auxiliary pinion 16 fixed coaxially therewith.
By meshing with the rack 14, reliable meshing with the rack 14 is achieved. The pressing plate 11 is a comb-shaped plate whose lower end can be inserted between the strips of the fork-shaped receiving shelf 10, and is arranged in a direction perpendicular to the veneer feeding direction. Further, this pressing plate 11 is located on the retreating position side of the receiving shelf 10, and is configured to be able to be pushed forward by a drive cylinder 19. The stacker 21 is the receiving shelf 10
It is located directly below the forward drive position. As the stacker 21, one that is configured to be movable up and down can be used, and the height can be adjusted by moving the stacking surface position up and down depending on the stacking height of the veneers. The ruler plate 20 is arranged so that its side edge and front surface align with the front side edge position of the stacker 21 when pressing the veneer, and when pushing down the veneer on the receiving shelf 10 with the pressing plate 11, the ruler plate 20 By abutting against each other, the falling position of the veneer is regulated.

The gluing mechanism section B for the intermediate veneer can be constructed by applying the existing spreader 30. The spreader 30 has upper and lower applicator rolls 32 and 32 to which glue is adhered to the surface from each transfer roll 31 and 31.
The medium veneer a is inserted in the direction of the arrow X between them to be glued, and the medium veneer sent out after gluing is received by a receiving shelf 34 that pivotally supports a plurality of tsuba rolls 33, 33... It is configured to be carried out in the direction.

The front and back veneer assembling mechanism section C includes a veneer assembling device 40 that stacks the front veneer b and the back veneer c, which are supplied separately, one above the other and adjusts the edges before sending them out. On the veneer delivery side of the veneer assembly device 40, as shown in FIG.
51 are arranged. These endless belts receive and support the front and back veneers, which have been overlapped with their edges aligned, from the assembly device 40 without shifting, and then send them out to the rear and carry them out. On the rear end side of each endless belt, there is further a pinching feed belt 5 disposed facing each other vertically.
2.53 is extended. These belts 52 and 53 are arranged obliquely so that their terminal ends are positioned diagonally downward, and are configured to pinch and support the veneer fed from the endless belts 50 and 51. The upper clamping belt 52 is connected to a turning wheel 54.
It is configured to be moved up and down by a cylinder 55 with the cylinder 55 as a reference point, and when it is raised, the veneer that was supported under pressure can be released. Furthermore, the veneer assembly device 40
The mechanism consisting of the pressure belts 50, 51, 52, and 53 can be configured to be arranged in multiple stages, and the number of sheets can be made to correspond to the gluing process of the medium veneer.

In the stacking device configured as described above, the middle veneer glued by the spreader 30 and the front and back veneers whose side edges have been adjusted and sent out from the pinch feed belt are alternately placed on the stacker 21 located in the center. It is to be loaded.

First, the intermediate veneers a are sequentially inserted and supplied one by one in the direction of the arrow X into the spreader 30 by one worker, and after being pasted between the applicator rolls 32, they are sent out in the direction of the arrow Y. In front of it, there is a receiving shelf 1
0 is driven forward by the operation of the cylinder 12 and is on standby to receive the veneer to which glue has been applied. When receiving a veneer is detected by a phototube or a limit switch, the receiving shelf 10 is driven backward and the pressing plate 11 is driven forward. As a result, the tip of the glued veneer on the receiving shelf 10 comes into contact with the ruler plate 20, and the veneer is dropped with its edge aligned with the side edge of the stacker 21.

On the other hand, the front and back veneers b and c, which have been stacked vertically with their edges adjusted by the assembly device 40, are fed between the endless belts 50 and 51 of the pinch feed belt. The endless belts 50 and 51 pinch and feed the front and back overlapping veneers in the direction of the arrow Z while being aligned by the assembly device 40, and feed them between the diagonally descending belts 52 and 53 on the extension thereof. The descending belts 52 and 53 stop and support the front and back polymerized veneers under pressure, and the adhesive veneer a
Depending on the supply state, the cylinder 55 is operated to release the sandwiched front and back overlapping veneer. Thereafter, the front and back laminated veneers are received by two workers placed on the left and right, and if the glued veneers are already loaded on the stacker, they are placed directly on top of them, or the glued veneers are placed on the receiving shelf 10. If it is placed on the shelf, it can be loaded on that shelf as appropriate. When stacking front and back overlapping veneers together with middle veneers on the receiving shelf 10, the three stacked veneers are pressed by the above-mentioned pressing plate 11, and the edges are pressed against the ruler plate 20 while the receiving shelf 10 is loaded. By moving the stacker 21 backward, the stacker 21 can be dropped and stacked in the aligned state.
In this way, the front, back, and middle veneers are stacked alternately, and the upper and lower front and back laminated veneers are combined into a set via the glued middle veneer, and then subjected to a heat pressing process.

If the number of front and back veneers supplied from the spreader 30 does not match the number of glued veneers supplied, the worker can carry them as necessary from the pile d of front and back veneers stored near the stacker 21. It can be supplemented as appropriate by stacking it on the middle plate veneer.

(Effects of the invention) According to the plate-like object receiving and stacking mechanism according to the present invention, everything from gluing the medium veneer to receiving and loading it can be performed automatically, making it possible to save labor and to It is possible to overlap the plates in an orderly manner.
