The veneer veneers 1a, 1b, and 1c are arbitrarily selected and supplied. For example, only the veneer veneer 1b is inserted, or the veneer veneers 1a and 1b are alternately inserted, and arbitrarily selected and supplied according to the product. Is done. The veneer veneer 1 supplied by the veneer veneer 1 is supplied to the veneer veneer 1 by a direction changing device 7 and the transport direction is changed in a direction orthogonal to the supply direction.

In this embodiment, the veneer veneers 1 of various sizes having different lengths in the fiber direction are conveyed and supplied from separately stacked positions. However, the present invention is not limited to this. , The turning device 7 from the position where it is stacked
Alternatively, the veneer veneer 1 may be transported and supplied one by one, and the direction changing device 7 may be omitted, and the veneer veneer 1 may be directly transported along the transport direction of the veneer veneer from the right side of FIG. Of course, it may be carried.

Reference numeral 4 denotes a fixed width detecting / discharging device based on a combination of a photoelectric switch 4a, a counter, a timer, and the like.
Are detected, and those (1d) smaller than a predetermined width (short side) are discharged. If the width of the veneer veneer is constant, the fixed width detection / discharge device 4 can be omitted.

Reference numeral 5 denotes a veneer veneer veneer 1 that has passed through the standard-size width detecting / discharging device 4.
Is temporarily stopped at an alignment position where the length and width are set in advance. In the single-plate aligner 5, first,
Front end (short side) of veneer veneer 1 in direction perpendicular to transport direction
The side, that is, the short side where scarf cutting is performed later, is aligned. For example, a fixed alignment plate is disposed on one side, and a movable alignment plate that can be moved in and out by an air cylinder or the like is disposed on the other side. Next, the veneer veneer 1 is transported in the reverse direction, and the right and left transports are controlled and stopped so as to be perpendicular to the transport direction by the photoelectric switch 5a disposed on the trailing edge (long side) side. For veneer veneer 1 having a certain thickness and sufficient rigidity, the leading edge or the trailing edge may be aligned using a vertically movable fixed stopper and a vertically movable movable plate as described above. Of course.

When the alignment is completed, the veneer veneer 1 is nipped and transported by a first veneer veneer nipping and transporting device 6 for nipping and transporting the veneer veneer 1 to the front cutting position without shifting the alignment. And stop it. When the veneer veneer 1 stops at the front cutting position, the veneer veneer 1 is clamped from above and below so that the veneer veneer 1 is not displaced, and the front end scarf cutting device 8 is operated to operate the veneer veneer. The front end side of 1 is cut into an upward or downward scarf slope to form a scarf veneer. Along with the operation of the front end scarf cutting device 8, the first veneer clamping and transferring device 6 releases the clamping, returns to the aligning position of the veneer aligning device 5, and prepares for the next clamping and transporting.

When the first veneer clamping / transferring device 6 starts to return to the aligning position of the veneer aligning device 5, the second veneer clamping / transferring device 9 arrives at the front cutting position and moves the scarf veneer up and down. Hold it from the direction to prepare for transfer.

Next, when the front end scarf cutting device 8 finishes cutting the front end scarf, the second veneer sandwiching and transferring device 9 starts transferring, and the second veneer sandwiching and transferring device 9 is arranged on the discharge side of the front end scarf cutting device 8. A pressing device 11 through an adhesive application device 10 such as a hot melt for applying an adhesive to an upward or downward front end scarf slope of a scarf veneer.
The scarf veneer is transferred to (joining position). The front end scarf slope of the transferred scarf veneer on which the adhesive is applied is superimposed on the rear end scarf slope of the scarf veneer that is waiting in advance, and the pressure is applied by the pressing device 11 from above and below. Bonded by cooling and pressing for 5 to 1 second to form a continuous band-shaped scarf veneer. (If a thermosetting adhesive is used, heat at a specified temperature for a specified time.)

A third veneer clamping / transporting device 12 clamps both sides of the joint immediately before or immediately after the end of the cold pressure by the pressing device 11 to prepare for the clamping / transfer of the joined veneer. After the completion of the cold pressure by the pressing device 11, the third single-plate holding / transporting device 12 transports the joint by a predetermined amount so that no extra force is applied to the joint. Since the rear end scarf cutting device 13 is disposed at a position that is a reference dimension, for example, 4 meters away from the pressing device 11 (joining position), for example, a scarf having a predetermined size longer than the reference size, that is, a length of 6 meters. When the veneer arrives, the supplementary transfer amount A is 6 m4-4 m = 2 m, and the third veneer holding and transferring device 12 nips and transports the supplementary transfer amount of 2 m. Here, the suspension is temporarily stopped, and the rear end portion of the single scarf is cut by the rear end scarf cutting device 13 on the downward or upward rear end scarf slope. A certain length of 4 is pinched and transported, and the rear end is
(Joining position) to prepare for the next joining.

The length of the veneer is selected in advance by means of a select switch or the like, and the veneer aligning device 5 and the third veneer sandwiching / transporting device 12 are controlled, or the direction changing device 7 or the standard size is used. It is disposed at a position such as the width detecting / discharging device 4 and automatically detects the length (long side) to control the single plate aligning device 5 and the third single plate sandwiching and transferring device 12 and the like.

Reference numeral 14 denotes a fixed-length cutting device for cutting a continuous band-shaped scarf veneer to a predetermined length, and 15 denotes a predetermined-length cutting device that passes through the fixed-length cutting device 14 and is cut. This is a deposition device for sequentially dropping and depositing scarf veneers. Note that the deposition device 15 may be omitted as necessary.

In the veneer veneer vertical peeling apparatus according to the present invention having the above-described structure, the rear end scarf cutting device 13 is disposed at a position spaced apart from the pressing device 11 (joining position) by a reference dimension, for example, four meters. For example, when a veneer veneer with a length of 6 m, which is a predetermined dimension longer than the reference dimension, arrives, the supplementary transfer amount A is 6 m-4 m = 2 m, The veneer veneer is moved downward or upward by the rear end scarf cutting device 13 so that the rear end of the veneer veneer is moved downward or upward on the rear end scarf slope. After the scarf cutting, the nipping and transporting is continued again, the nipping and transporting is performed for a length of 4 lengths, which is the remaining transporting amount B, and the rear end is stopped at the pressing device 11 (joining position) to perform the next joining. Equipped with the front end scarf cutting device 8 Each time the front-end scarf slope coated with an adhesive arrives on the front-end scarf slope, it is superimposed on the rear-end scarf slope of the scarf veneer, and cooled and clamped from above and below for 0.5 to 1 second by the clamping device 11. To form a continuous strip-shaped scarf veneer.

Next, the continuous band-shaped scarf veneer is cut to a predetermined length by the standard-length cutting device 14 to produce a fixed length veneer. Hereinafter, by repeating the same operation, it is possible to continuously manufacture a fixed length veneer efficiently using various types of veneer veneers having different lengths.

[0018]

As described above in detail, the veneer veneer vertical peeling device according to the present invention has the minimum length dimension among various types of veneer veneers having different lengths in the fiber direction. The veneer veneer with a longer dimension is determined based on the cut end of the veneer at the rear end of the veneer, and the veneer veneer that has a longer dimension is corrected and moved so that it is always positioned at the cut end of the scarf at the rear end and joined to the subsequent veneer veneer. Therefore, even if various types of veneer veneers having different lengths in the fiber direction are used, there is no need to change and adjust the cutting position each time, unlike the conventional equipment. Since test cutting for correcting an unbalanced scarf cutting dimension is not required, there is an effect that a vertical single-ply board can be manufactured efficiently and with good yield.
