DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for orthogonally transferring a veneer cut into a rectangular shape from a conveyor to an adjacent position.

[0002]

2. Description of the Related Art Conventionally, when stacking a veneer after gluing and another veneer, not only is it inefficient by hand, but also the damage ratio of the veneer is very high, and there is a problem in the continuity of work. Therefore, there have been various proposals for mechanically processing this.

For example, a veneer veneer automatic stacking device proposed in Japanese Utility Model Publication No. 49-33725 reports a veneer veneer in which a top plate and a back plate are superposed as a pair by a suitable means. The veneer fork, which has been conveyed by a conveyor and has been waiting beneath the conveyor, places the superposed veneer and transports it to the laminating table in front. When the fork for transporting the veneer comes down onto the laminating table, the fork for transporting the veneer descends and retreats to the original position, but the laminated veneer is placed on the laminating table by the stopper installed on the laminating table. .
This series of movements of the veneer transfer fork is accompanied by the rotation of the chain to which the arm portion of the veneer transfer fork is pivotally attached.

When the laminated veneer has been placed on the laminating table, the veneer that has passed through the gluing machine from one side is placed on the laminated veneer on the laminating table by appropriate means. If the laminated veneer, the glued veneer and the laminated veneer are placed alternately on the laminating table in this way, one of the first veneered veneer, the glued veneer and the next are sent. One plywood material is constituted by three veneers, one of the superposed veneers.

[0005]

As described above, when a veneer is transported by the veneer fork for veneer transfer and placed on the laminating table using a stopper, a plurality of forks for veneer transfer are used. Are arranged side by side on the same plane, so that the veneer placed on it is flat and the side edges of the veneer that abut against the stopper have small waviness, but they are almost horizontal when viewed as a whole. Become.

[0006] However, this kind of veneer cut into thin plates from raw wood has relatively high strength in the direction of wood fiber,
Since it is fragile in the direction perpendicular to the wood fiber, there is no significant bearing when aligning the edges in the wood fiber direction, but the edge perpendicular to the wood fiber is rounded, especially as a single veneer as described above. If the edges of the veneer veneer that are prone to drop are abutted by the stopper when the transfer fork is retracted, the veneer will buckle due to the impact at that time, and the veneer will be damaged or the buckle will cause the veneer position to drop. Shift, resulting in reduced productivity.

[0007]

SUMMARY OF THE INVENTION In order to solve the problems of the prior art, according to the present invention, when a veneer for transferring veneer is placed on a veneer, both ends of the veneer are placed. Are arranged in each row interval of the veneer conveyor so that the veneers are curved in the upward direction, and can be moved up and down with respect to the conveyance surface of the conveyor, and can reciprocate orthogonally. The fork is characterized in that its veneer support surface is positioned higher on the outside than on the inside.

In particular, the inner veneer fork for transferring a veneer is
Arranged so that the veneer support surface extends almost horizontally at the specified height.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention;

In FIG. 1, 1 is a hydraulic lifter for depositing a veneer 2 to be glued, 3 is a pinch roll for inserting the veneer 2 to be glued into a gluing machine 4, and 5 is a gluing machine. A veneer transport conveyor using a roll with a flange for transporting the glued veneer which has passed through 4, and a front stopper 6 attached to the tip of the veneer can cope with a change in length of the veneer in the transport direction. And a veneer moving device 7 is additionally provided. In the drawing, reference numeral 8 denotes a laminating table for depositing a plywood material in which a veneer or a superposed veneer is laminated with front and back glued veneers glued on both sides by the gluing machine 4.

Next, the details of the single-plate moving device 7 in FIG. 1 will be described with reference to FIGS. 2 and 3. The chain wheel 1 driven by the prime mover 9 through the chain 10 will be described.
Arms 14 are fixed at upper and lower portions to chains 13, 13 'suspended between 1, 11' and driven chain wheels 12, 12 ', and a connecting piece 15 is attached to the tip. Have been.

On the upper surface of the connecting piece 15, a plurality (four in the illustrated example) of the connecting piece 15 are arranged at an arbitrary interval in the longitudinal direction thereof so as to be located within the interval of the conveyor 5 using the flanged roll. The single-plate transfer forks 17, 17 'are attached in the same direction as the transport conveyor 5 using a flanged roll via the attached attachments 16, 16'. At this time, the veneer support surfaces of the veneer transfer forks 17, 17 'are made higher at the outer position than at the inner position to impart rigidity to the vulnerable veneer.

For example, if the heights of the attachments 16 and 16 'are the same, the thickness of the veneer transfer forks 17 and 17' is made thicker as it is located on the outer side, and conversely vice versa. K17,
If the thickness of 17 'is the same, the attachments 16, 16' for supporting the single plate transfer forks 17, 17 'as shown in FIG.
Set by height.

The veneer support surfaces of the veneer transfer forks 17, 17 'are inclined downward from the base end toward the distal end to reduce frictional resistance during veneer transfer.

Further, when the veneers are transferred from the veneer transfer forks 17, 17 ', if the transfer of the square pipe is shifted by 45 degrees as shown in FIG. In addition to reducing the sliding resistance with the back surface of the plate, when glue is applied to both the front and back surfaces of the veneer, the peeling of the glue applied to the back surface can be reduced.

Reference numeral 18 denotes a side stopper for placing the front and back glued veneers 19 on the veneers 17 and 17 'for transferring veneers on the laminating table 8. The fork for veneers can be moved forward and backward. As shown in FIG.

In the embodiment shown in FIG. 5, the veneer supporting surface adjacent to the veneer fork 17 has a height difference, and particularly, the veneer to be transferred is a long veneer 20 or a thin single veneer. It is effective when it is a board.

Next, the operation will be described. First, the case of a three-ply plywood will be described. While the laminated veneer is placed on the laminating table 8 by appropriate means, the veneer glued on both sides by the gluing machine 4 is transported by the veneer transport conveyor. The progress is stopped by the front stopper 6.

With the driving of the prime mover 9, the chain wheel 1
By rotating 1, 11 ', 12, 12', chain 13,
The arm 13, which is pivotally connected to the upper and lower points of the chains 13, 13 ′, rises and is immersed below the conveying surface of the conveying conveyor 5 in a standby state in a state of being immersed. -K1
7, 17 'are projected.

At this time, the front and back glued veneers 19 are placed on the veneer transfer forks 17 and 17 'from the transport conveyor, and the arm 14 moves in the orthogonal direction with the continuous driving of the motor 9. When it starts to move, the front and back glued veneer 19 is transferred to the veneer transfer form.
And move in the orthogonal direction while being placed on the bases 17, 17 '.

As shown in FIG. 4, the veneer transporting forks 17 and 17 'are located at both ends of the veneer transporting forks 17 and 17' at both ends of the veneer transporting fork 17 at the center. Since 17 'is located at a higher position, the rear end of the front and back glued veneer 19 has a curved shape in which both ends are warped upward.

The fork for transferring the veneer reaches the position shown by the chain line in FIG. 2, and furthermore, the chain wheels 11, 11 ', 12, 12'.
When the fork 1 is rotated in the direction of the arrow shown in FIG.
The rear end of the single-sided glue veneer 19 on the front and back 7 and 17 'is the stopper 1
However, as described above, the rear end of the front and back glued veneer 19 has a curved shape in which both ends are warped upward, and the side end of the veneer is attached to the veneer itself as compared with the horizontal one. Since the rigidity in the longitudinal direction is provided, the buckling of the front and back glued veneers 19 and the displacement of the front and back glued veneers 19 due to the buckling can be prevented even when the stoppers 18 abut.

Further, fork 17 'for transferring single plate at both ends.
The fork 17, 17 'for transferring the veneer is easily removed from the veneer 19, and the whole fork 17, 17' for transferring the veneer is formed into a square pipe having a phase of 45 degrees. As a result, the friction with the front and back glued veneers 19 is reduced, and the glue on the back surface of the front and back glued veneers 19 is almost completely removed without being peeled off. Can be stacked.

Further, even if the veneer to be transferred is a long veneer 20, as shown in FIG.
The position of 7 is set alternately with high, low, high and low in the longitudinal direction,
If the veneer is formed into a continuous curved shape, rigidity can be imparted in the same manner as described above.

In this manner, only the front and back glued veneers 19 are stacked on the superposed veneer on the laminating table 8 by the stopper 18, and the veneers 17 and 17 'for transporting the veneers are chained.
It returns to its original position by traveling 3, 13 ', and waits for the next front / back glued veneer 19 to be transferred.

As described above, if the veneer veneer, the veneered glue veneer, and the veneer veneer are alternately placed on the laminating table 8, one of the first veneer veneer fed is glued to the back veneer. A single plywood material will be composed of three veneers, a veneer and one of the superimposed veneers sent next. The configuration is not limited to three, but may be appropriately selected.

Although the present invention has been described with reference to the transfer of glued veneer in the plywood manufacturing process, the present invention is not limited to this. It is informative.

[0031]

As described above, since the above-mentioned effects are obtained in each claim, accurate positioning can be achieved even when a vulnerable veneer is orthogonally transferred in the transport direction, and the veneer can be stacked efficiently. Improvement, smoothness in stacking of veneers and improvement of products can be achieved, and high quality products can be obtained.
