Description

[Detailed Description of the Invention] The present invention relates to a method for bonding panels,
More specifically, in the present invention, a cutter 2 that protrudes from the bottom surface of the suction head 1 and can cut the pinning plate 5 is cut on the side surface of the suction head 1, and the suction head 1 is depressurized to loosen the pinning plate 5 into a convex shape to perform suction. Then, the plurality of suction heads 1 are brought together and brought into contact with each other, the depressurization of the suction heads 1 is stopped, and the end surfaces 7 of the plywood sheets 5 are placed on the adhesive-coated plywood 6, with the end faces 7 butted together without any gaps, and the central part This relates to a method for attaching attached plates, which is characterized in that the attached plates 5 and 6 are laminated together by placing the attached plates in a slack state and then pressing them.

When making wall materials by gluing together multiple veneers obtained by slicing the veneers from a flitch made of precious wood onto plywood, the veneer veneers are coated with adhesive in order to align the edges of the veneers without any gaps. When placing on coated plywood 1. It is necessary to loosen the hoof a little before compressing it.

To do this, the conventional method was to cut the edges of the stacked boards using a cutter similar to a guillotine, and then place them on top of the adhesive-coated plywood, aligning the edges one by one while still leaving some slack at the ends. It was arranged like this.

However, since this work (loose bonding work) is complicated, it has conventionally been difficult to obtain a good product unless two workers work together.

Furthermore, since the work was done manually, it was difficult to avoid product variations.

The present invention has been made in view of the above-mentioned points, and its purpose is to automatically, by a machine, perform the loosening and gluing work of aligning the end faces of a plurality of plywood boards without any gaps and gluing them together on plywood. The aim is to provide a method that can be used to

Next, the present invention will be explained with reference to embodiments shown in the figures.

Figure 1 is a perspective view of plywood with attached boards,
5 is a board, 6 is a plywood like plywood, and 7 is an end face of the board.

In order to obtain such a laminated board, the following method is performed.

First, load the veneer plate on the support plate 8 [see a in Fig. 2], and press it with the suction head 1 [b in Fig. 2].
reference〕.

As shown in Fig. 3, the suction head 1 has a box-like shape, with a decompression air port 3 at the top for discharging air and reducing the pressure, and a suction hole 4 at the bottom. can be,
When air is removed from the reduced pressure air port 3 using a vacuum pump or a decompression pump (not shown), the inside of the box-shaped suction head 1 becomes under reduced pressure. It has an adsorption structure.

Next, the sticking plate 5 held down by the suction head 1 is cut on both sides of the suction head 1 by a cutter 2 that can cut the sticking plate 5 by protruding from the lower surface of the suction head 1 (see C in FIG. 2).

Regarding this cutting, when the attached plate 5 is loosened in a convex shape and adsorbed, and the attached plate 5 is placed on the base plate 6 coated with adhesive, the central part of the attached plate 5 is loosened. In condition and with plate 5
In other words, so that the end surfaces 7 of
In order to compensate for shrinkage during the process of attaching plates, the dimensions of the attached plates are cut to be larger than the dimensions of the attached final product.

Here, as a cutter, in order to position the tip 2a of the blade on the outside of the suction head 1, a side 2b in which the cross section of the tip of the blade slopes from the suction head 1 side to the outside and downward of the suction head 1 is defined as one side. Use one with a triangular shape.

The cutter plate 5 is cut while suction is being performed with the tip 2a of the blade of the cutter 2 protruding downward from the suction head 1 and positioned outside the suction head 1.

After cutting, the suction heads 1 that have suctioned the plurality of attached plates 5 are brought together and brought into contact with each other.

[See d in Figure 2]. The contact needs to be made with each attached plate 5 remaining convex and slack.

Next, the depressurization of the suction head 1 is stopped, and the adhesive plate 5 is placed on the adhesive-coated plywood 6 with the end faces facing each other without any gaps and the central part loosened (the adhesive (Due to the force, the plate may remain slack) (Fig. 4a)
reference).

Then, by pressing, a bonded plate with a good appearance in which the end faces of the attached plates are bonded together without any gaps is obtained.

In the above example, the attached plate was cut while being sucked by the suction head, but if the structure of the suction head and the structure of the cutter were changed, the plate could be cut by the side of the suction head while being held down by the suction head instead of being cut while being suctioned. Can be cut.

In the present invention, the plate is cut on the side surface of the suction head with a cutter that can protrude from the lower surface of the suction head and cut.
The suction head is depressurized, the board is loosened into a convex shape and adsorbed, the multiple suction heads are brought together and brought into contact with each other, the depressurization of the suction head is stopped, and the end surface of the board is placed on the plywood coated with adhesive. The plywood and the plywood are placed together with no gaps between them, with the center part loosened, and then pressed to bond the plywood to the plywood, so the work of bonding the plywood does not require any manual labor and is done automatically. In addition, it is possible to obtain products in which the end faces of the attached plates are uniform without any gaps.
