Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic selving machine for laminated wood, which uses a cutter to cut the protruding portions at both ends of a decorative laminate made by bonding a plurality of veneers together and pasting them on the surface thereof.

Conventionally, this type of automatic selvage machine has been provided that uses four cutters (top, bottom, left and right) to cut the protruding parts on both sides of a decorative board attached to the top and bottom surfaces of laminated wood that is transported in one direction. .

However, this method has the disadvantage that the upper left and right cutters are attached to the rotating shaft of an electric motor installed with the rotating shaft facing downward, making it difficult to attach, detach, and adjust the cutter or copying roller. ing. In addition, in order to make it possible to process laminated wood with different dimensions, electric motors (cutters, copying rollers) and some conveyor rollers can be moved up and down or in the width direction, but these are installed independently. Therefore, all of these items must be moved and adjusted one by one, which is extremely complicated.

The present invention has been made in view of the above drawbacks.
The purpose of this is to arrange the cutters for rough finishing, finishing, and chamfering from the entrance side of the laminated wood conveyance, so that the edge removal work can be performed smoothly. By installing it almost upward, it is possible to easily attach and detach and adjust the cutter or copying roller, and the electric motor can be installed on one side and the other side of the conveyance path, respectively, on a fixed base and a sliding base. and by providing means for integrally moving each electric motor up and down on one side and the other side,
To provide an automatic selving machine for laminated wood that facilitates the overall position adjustment of shavings, etc.

It has a slightly larger diameter than 11d. This copying roller 80
The board 81 with the attached board 81 can be moved in the width direction of the conveyance path with respect to the hood 78, and the amount of movement is adjusted by rotating the bolt 82. That is, as shown in FIG. 8, the copying roller 80 is loosely fitted to the rotating shaft 47, and is attached via a bearing 83 provided so as to be movable toward the conveyance path by a bolt 82. Therefore, as shown in FIG.
Adjustments are made so that the tips coincide with or protrude slightly depending on the degree of wear of a to 11d.

Next, the chamfering means will be explained.

This is installed in front of the frontmost cutters 10a and 10b, and the electric motor provided with the cutter 12a is attached to the lifting frame 61 and can move up and down together with the lifting frame 61. Katsuta 12b
The electric motor 90b equipped with this is attached to a post 91 provided on the slide base 25 via a slide member 92. The slide member 92 is the post 91
The upper end of the threaded rod 93 is connected to the threaded rod 60 by a chain 94. Therefore, the electric motor 9
0b (cutter 12b) is the upper cutter 10a, 10b
It is possible to move up and down in synchronization with etc. Also, Katsuta 1
The electric motor equipped with 2c and 12d has a fixed base 20,
Like the electric motors 45c and 45d of the lower cutters 10c and 10d, they are installed on a post provided on the slide base 25 so as to be movable up and down by a slide member, and the vertical position is finely adjusted by rotating a threaded rod. . As shown in Fig. 6, the above electric motor has a cutter 1.
It is slidable on a shaft 95 inclined at the same angle as 2b, etc., and is elastically biased toward the conveying path side by a compression coil spring 96. In addition, the hood 78 has an L
A shaped copying member 97 is attached, and this copying member 97 is attached to the cutter 12a in the same way as the copying roller 80 described above.
The position can be adjusted using a bolt 82 in order to match the tip of 12d. Furthermore, as shown in FIG. 9, the cutters 12a to 12d and the copying member 97 are movable in the axial direction by compression coil springs 99, 99 relative to the rotating shaft 47 of the electric motor and a shaft 98 provided on the hood 78. ing. That is, the cutter 12a
12d, the copying member 97 is movable in two directions shown by arrows in FIG. 9, and can cope with warping of the laminated timber 1.

In the above configuration, the laminated timber 1 is
From the left to the right in the figure, each roller 35, 36, 3
7, 38a, 38b, 39, 40, 41, and first, the protruding parts 2a, 3a on both sides of the decorative boards 2, 3 are cut into rough finishing cutters 11a to 11d.
Rough cutting is performed with a finishing cutter 10a~
Finish cutting is performed at 10d. At this time, the copying roller 80 comes into contact with both sides of the laminated wood 1, and the laminated wood 1
Cutters 10a to 10d, 11a to 11 for sledding, etc.
Follow the tip of d. After the protrusions 2a and 3a on both sides are cut, the chamfering cutters 12a to 12d are cut.
Chamfering is performed at.

If the width and height dimensions of the laminated timber 1 are different, turn the handle 27 in the width direction to move the slide base 25 with respect to the fixed base 20, and use the cutters 10b, 10d, 11b, 11d, 12b,
12d, adjust the position of the guide roller 38b.
In the height direction, turn the handle 68 to remove the cutters 10a, 10b, 11a, 11b, 12a, 1.
2b, adjust the positions of guide rollers 39, 40, and 41; That is, by operating the handles 27 and 68, the position in the width direction and height direction can be easily adjusted.

As is clear from the above description, in the present invention, the cutters are arranged for rough finishing, finishing, and chamfering from the laminated timber conveyance entrance side, so that the edge cutting work can be performed smoothly. Further, by installing the electric motor for attaching various cutters with its rotating shaft facing substantially upward, the attachment/detachment and adjustment work of the cutter or copying roller can be facilitated. In addition, the electric motors are divided into one side and the other side of the conveyance path and attached to a fixed base and a slide base, respectively, and a means is provided to move each electric motor up and down integrally on one side and the other side. By integrally moving one side and the other side, it becomes easy to adjust the overall position, for example, to adjust the reference position for each laminated timber of different size.
