2. Description of the Related Art As a conventional veneer veneer (hereinafter referred to as veneer) lifting device, the device described in Japanese Patent Publication No. 54-16304 is known. The device has, for example, the structure shown in FIG. 1, and includes a push rod 6, a pair of auxiliary arms 2, 2a,
A pair of piercing arms 1 and 1a having a needle material B and a guide plate 7 slidable in the restriction member 6 are pivotally attached by shaft pins 3, 4, and 5 to form a frog-shaped link mechanism. ing. When the regulating member 6 presses the accumulated veneer from above, the needle material B pierces the veneer and then the lower end portion 7b of the guide plate 7 is pushed.
The puncture regulation surface A of the above press-contacts the upper surface of the single plate. When it is further pressed, both auxiliary arms 2 and 2a open outward with the shaft pin 5 as a fulcrum as the push rod 6 descends, and the piercing arms 1 and 1a also move the shaft pins 3 and 3 of the lower end portion 7b of the guide plate 7. As a center, turn each on the left and right. By turning the piercing arms 1 and 1a, the needles B at the tips of the arms 1 and 1a pierce the veneer, and the tips of the needles B approach each other to clamp the veneer from the left and right.

However, such a conventional device has the following problems. That is, the push rod is linearly moved from above the deposited veneer to the upper surface of the veneer (direction of arrow Z in FIG. 2), and the veneer B is inclined with respect to the direction of the veneer. When the needle is pierced, the single plate is compressed and broken at the Y portion (see FIG. 2) of the needle material B, and a void H is generated. The so-called veneer is destroyed more than necessary.

Next, the operation of the first embodiment constructed as described above will be described with reference to FIGS. 3, 4 and 5. The regulating member 18 moves upward, and the contact portions 14, 14 of the arms 13, 13a
a is in contact with the regulating member 18 due to the moment due to its own weight, and the mounting plate 11 is in the initial state of standing by above the deposited veneer.
The distance from the claws 17 and 17a to the surface layer of the veneer to be stabbed with the veneer 7 and 17a is adjusted by an appropriate detection device (not shown) on the lift table (not shown) accumulating the veneer. The height is controlled, and a distance shorter than the vertical stroke of the mounting plate 11 is always maintained by the thickness of one single plate. Further, a signal from the controller is appropriately set by a timer through a delay device (not shown) such as a timer, the time required for lowering and raising the mounting plate 11 and lowering and raising the regulating member 18.

From the initial state, when a signal from the controller causes the mounting plate 11 to descend substantially linearly from above the deposited veneer in the surface layer direction of the veneer, the claws 17 of the arms 13 and 13a,
When the tip of 17a comes into contact with the surface of the single plate 9 as shown in FIG. 4-a, the state becomes a partially enlarged view of FIG. 5-a. Further, when the mounting plate 11 descends and the descending ends, the claw 1
7 and 17a pierce the veneer 9 and the stoppers 16 and 16a abut the veneer 9. As shown in FIGS. 5A to 5B, when the tips of the claws 17 and 17a come into contact with the single plate 9, the fulcrum shafts 15 and 15a are used as fulcrums to support the arm 1
A moment acts on 3, 13a, and as the mounting plate 11 descends, the claws 17, 17a pierce the single plate 9 while rotating in the direction of arrow P. As a result, the pawls 17 and 17a are stabbed while rotating from the position of the one-dot chain line E (see FIG. 5-a) to the position of the two-dot chain line J (see FIG. 5-b). Further, due to this rotation, a gap S (see FIG. 4-b) is formed between the contact portions 14, 14a of the arm and the regulating member 18. After all, the mounting plate 11 moves linearly, but the claws 17 and 17a pierce the single plate while rotating.

Next, after the lowering of the mounting plate 11 is completed, the regulating member cylinder 21 is actuated by the signal from the controller to lower the regulating member 18. As a result, the restricting member 18 pushes the abutting portions 14 and 14a of the arms, and further rotates the arms 13 and 13a, so that the claws 17 of the arm 13 and the claws 1 of the arm 13a.
The single plate 9 is sandwiched with 7a. That is, by pressing the contact portions 14 and 14a of the arms 13 and 13a with the restricting member 18, the veneers 17 and 17a hold the single plate 9 more reliably.

Subsequently, after the lowering of the regulating member 18 is completed, the mounting plate 11 is raised by a signal from the controller, and the claws 17 and 1 are provided.
The veneer 9 sandwiched by 7a is lifted. Next, the mounting plate 11
After the end of the ascending, the lifted veneer 9 is horizontally moved in a required direction by a signal from the controller, and the veneer 9 is transferred to another conveying device or the like. At the same time, the regulating member cylinder 21 is operated to raise the regulating member 18. Then, with a signal from the controller, the mounting plate 11 is returned to the original position and returned to the initial state. By repeating the above, the veneer is sequentially lifted.

According to the first embodiment, even if the claws 17 and 17a are inclined with respect to the linear movement of the mounting plate 11, the claws 17 and 1 can be moved.
Since the 7a rotates and pierces the veneer, the claws 17 and 17a do not break the veneer more than necessary.
