Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a sliced veneer for manufacturing decorative plywood by pasting a plurality of sliced veneers preformed in a predetermined shape on a substrate in a predetermined arrangement. This invention relates to a board bonding device.

(Prior art and its problems) Conventionally, when manufacturing natural wood decorative plywood with a design such as a checkered pattern on the decorative surface, a wood-framed flitch is sliced with a slicer so that the desired unit design is formed on the cross section. The sliced veneer of a predetermined shape obtained by side-cutting is
A plurality of sheets are usually pasted on a substrate such as plywood in a predetermined arrangement and direction, such as in a checkerboard pattern, so that a desired design is realized on the decorative surface.

However, when pasting each sliced veneer onto the board, it is necessary to adjust the position, direction, and arrangement of the veneers so that the desired design is achieved. It is common that the process is carried out in a similar manner, and not only is the work efficiency extremely low, but it also has problems such as the fact that the sliced veneer often lifts due to poor adhesion.

(Object of the Invention) In view of the above circumstances, the present invention provides sliced veneer bonding that can significantly improve work efficiency in the process of gluing sliced veneers and eliminate the possibility of floating of sliced veneers due to poor adhesion. Its purpose is to provide equipment.

(Structure of the Invention) For this reason, the sliced veneer bonding device according to the present invention is capable of slicing a plurality of sliced veneers, each of which has been formed in a predetermined shape, on a substrate in a predetermined arrangement to produce decorative plywood. The veneer adhesion device includes a rotatable sliced veneer suction support portion having a plurality of suction support surfaces in an outer circumferential direction for suctioning and supporting the plurality of sliced veneers, and an adhesive applied to the veneer adhesion surface. a substrate pressing unit that presses the sliced veneer substrate against the suction support surface at a predetermined rotational position of the sliced veneer suction support unit; The plurality of sliced veneers are pressed and transferred onto the veneer adhering surface of the substrate by the substrate pressing section.

That is, instead of directly pasting sliced veneers one by one onto a substrate coated with adhesive.

A plurality of sliced veneers are temporarily attached in a predetermined arrangement on the suction support surface of a rotatable sliced veneer suction supporter, and the plurality of sliced veneers temporarily attached in this manner are applied at the same time with a desired pressing force. This is a pressure transfer method that allows all veneers to be firmly attached to the substrate, and it is possible to attach the veneer to the substrate using adsorption force, rather than directly attaching the veneer to the substrate coated with adhesive. Since the plates are arranged, it is extremely easy to modify the position or direction during the temporary adhesion work, and work efficiency is dramatically improved in this respect as well.

(Embodiment of the Invention) The illustrated sliced veneer bonding apparatus includes a sliced veneer suction support section 1 that supports a sliced veneer (not shown) by vacuum suction, and a sliced veneer suction support section 1 that supports the sliced veneer by suction. It is composed of a substrate suppressing section 2 that presses the substrate X coated with an adhesive.

The slicing medium plate suction support part l includes a suction drum 3 formed in the shape of a hollow prism with both ends closed and supported by a crosspiece frame 100 so as to be rotatable around an axis, and a vacuum for suctioning the air inside the suction drum 3. It is composed of a pump 30.

The suction drum 3 has a large number of suction holes 5 formed therethrough at predetermined intervals on each of the four side peripheral surfaces 4a to 4d, and operates the vacuum pump 30.

When this is done, a desired suction force is generated in the suction holes 5. That is, each of the side circumferential surfaces 4a to 4d is configured to function as a suction support surface for a sliced veneer (not shown). Each adsorption support surface 4a-4
d are formed to substantially match the size of the substrate X, and the positional relationship of the temporary adhesion of each sliced veneer can be easily checked by the ruled lines 5a written on the surface thereof. Further, a sprocket 8 to which the rotational driving force of an electric motor 6 attached to a crosspiece frame 100 is transmitted via a chain 7 is attached to one end of the rotating shaft 31 of the suction drum 3, while the other end is attached to a sprocket 8. , vacuum pump 3o
It is connected to the suction side of the tube 32 by a tube 32. That is, the rotating shaft 31 of the suction drum 3 is formed into a hollow shape with one end closed, and is open to the internal space of the drum at a predetermined location within the suction drum 3, and the air inside the drum is pumped through the vacuum pump 30. It is configured to be sucked in and discharged.

The substrate suppressing unit 2 includes an elevating mechanism 10 that presses the substrates X, whose upper surfaces are coated with adhesive, which are sequentially transported by the transport mechanism 9, toward the suction support surfaces 4a to 4d located at the lower end of the suction drum 3. It is made up of.

This lifting mechanism 10 includes a main lifter 12 that is lifted and lowered by a pair of air cylinders 11φ11, and a main lifter 1
It has a two-stage configuration with sub-lifters 13 that are raised and lowered by sub-air cylinders 12a, respectively, on the substrate X, and a predetermined pressing force is applied to the substrate X by the driving force of the main cylinder 11, The cylinders 12a are configured to be able to uniformly press and contact the substrate X regardless of the unsurrage marks on the suction support surfaces 4a to 4d.

In the structure as described above, the adhesion is performed on the suction support surface located on the upper end side of the suction drum 3, that is, on the suction support surface 4a in the case shown in the first figure, in the same direction or arrangement as that on the substrate X. When the veneer slices are placed one after another, the vacuum pump 3
Due to the suction force acting through the suction holes 5 due to the operation of 0, the predetermined slice intermediate plates are temporarily attached to the suction support surface 4a. When the temporary adhesion of the sliced veneer onto the suction support surface 4a is completed, the suction drum 3 is moved to 9
Rotate 0a to perform temporary attachment of the sliced veneer onto the next suction support surface 4b, and then repeat this temporary attachment of the sliced veneer sequentially onto the suction support surface 4C and suction support surface 4d. On the other hand, when the suction support surface of the temporary adhesion method for the sliced veneer reaches the lower end of the suction drum 3, that is, the suction support surface 4c position in FIG. By driving the elevating mechanism 10 upward to move the substrate They are transferred to the substrate X all at once in the same arrangement.

Note that this substrate pressing work can be completed sufficiently within the time required for temporarily adhering the sliced veneer onto the suction support surface, and the substrate pressing work can be completed in sequence each time the suction drum 3 rotates as the temporary adhesion work is completed. It is something that can be repeated. Further, the substrate X after the slice veneer transfer is automatically carried out of the apparatus by rotating the transport mechanism 9 after lowering the lifting mechanism 1O.

(Effects of the Invention) According to the sliced veneer bonding apparatus according to the present invention, after temporarily adhering the sliced veneers in a predetermined position, they are transferred all at once onto the substrate with a predetermined pressing force. With this configuration, the working efficiency of the sliced veneer bonding process is improved, and there is no possibility that the sliced veneer may float due to poor adhesion.
