Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wood veneer conveying device for conveying a wood veneer obtained by slicing a wood veneer assembly.

The veneer 1 obtained by slicing the assembled fritchi with the slicer 10 is conveyed by the conveyor 2, and when stacking the veneers 1 to be sent to the next process, the veneer 1 is removed from the slicer 10 as shown in Fig. 1. If they come out diagonally, the veneers 1 can be aligned and stacked.

Since this is not possible, conventionally, workers have manually corrected the slant of the veneers 1 so that the veneers 1 can be stacked in alignment. In other words, since this veneer 1 is usually thin and long, it is difficult to correct the slant of the veneer 1 by abutting it against a stopper, so conventionally it was done manually. There was no other way to rely on it. The present invention has been made in view of the above points, and is made of wood that can automatically straighten, align, and stack veneers that are fed diagonally without requiring manual labor by workers. The object of the present invention is to provide a veneer conveying device.

The present invention will be explained in detail below with reference to Examples.

A plurality of conveyors 2 are arranged between a slicer 10 for slicing the fritchi and a place where the veneers 1 obtained by slicing the fritchi are stacked. The conveyor 2 is formed by vertically opposing a feed belt 12 driven by a pulley 11 and a presser belt 14 driven by a pulley 13, and as shown in FIG. The veneer 1 is conveyed by being sandwiched between the slicer 12 and the presser belt 14 to prevent the veneer 1 from curling. Sensors 3 and 4 are arranged at the same distance. Furthermore, chuck devices 5 and 6 are arranged near the sensors 3 and 4. The chuck devices 5 and 6 are connected to a base plate 15 by a pair of drives. The frames 16 and 17 are crossed and pivoted so that they can freely move up and down, and chuck tools 18 and 19 are attached to the tips of the drive frames 16 and 17, and the drive frames 16
, 17 are provided with air cylinders 20 and 21 attached to their rear ends, respectively. The drive frames 16 and 17 are rotated by the operation of the air cylinders 20 and 21, and the chuck tools 18 and 19 are rotated.
A chuck is performed in between. Chuck tool 18, 1
Balls 22 and 23 are rotatably attached to 9. However, when the veneer 1 whose frits are sliced by the slicer 10 comes out of the slicer 10 obliquely, and the veneer 1 is conveyed obliquely by the conveyor 2 as shown in FIG. When one end a of the veneer 1 located in front advances to the vicinity of one sensor 3, the sensor 3 detects the progress of the one end a of the veneer 1, and the sensor 3 is sent to the air cylinder 20 of the chuck device 5.

The air cylinder 20 is controlled at a low pressure, and is normally kept at a constant pressure, so that the chucks 18 and 19 are kept open. Now, like this, sensor-3
When a signal is input, the pressure in the air cylinder 20 becomes low and the distance between the rear ends of the drive rods 16 and 17 is narrowed.
One end a located diagonally forward of the veneer 1 is the chatter tool 1
A check is made between balls 22 and 23 of balls 8 and 19. When one end a of the veneer 1 is held in the chuck in this way, the other end of the veneer 1 is positioned diagonally rearward due to the rotation of the balls 22 and 23 while the one end a is prevented from moving. Part b moves as the conveyor 2 is driven, and as the veneer 1 horizontally rotates around the balls 22 and 23, the other end b of the veneer 1 advances onto the sensor 4 as shown in FIG. When the slant of the veneer 1 is corrected accurately and the approach of the veneer 1 is detected by the sensor 4, a signal is sent to the chuck device 5 to release the chuck and correct the slant. In the corrected state, the veneers 1 are sent by a conveyor 2 and stacked in an aligned state. The veneers 1 arranged and stacked in this way are sent to the next process, where the veneers 1 are pasted onto a board as a veneer, and
It is used to finish decorative boards, etc.

In addition, when the veneer 1 is tilted in the opposite direction to the above, the chuck device 6 is first activated by the detection by the sensor 4, and the chuck by the chuck device 6 is released by the detection by the sensor 3, contrary to the above. Similarly, it corrects the inclination of the veneer 1, and also prevents the veneer 1 from being slanted.
If it comes out from 0, the veneer 1 is connected to both sensors 3,
4 simultaneously, the signal from sensor 3 and the signal from sensor 4 cancel each other out, and chuck devices 5 and 6 are not activated, and veneer 1 passes through as is.
The chuck devices 5 and 6 have chuck devices 18 and 19 mounted on a U-shaped base plate 15 so as to be able to move toward and away from each other, as shown in FIG.
A check may be made at steps 2 and 23. As described above, according to the present invention, a pair of sensors detects a veneer that is sent diagonally on a conveyor, and a chuck device checks and releases the chuck at the end of the veneer, so that no manual work by an operator is required. The veneers can be automatically corrected without the need for veneers, and the veneers can be stacked in an aligned state and sent directly to the next process.

Moreover, the chuck device is equipped with a pair of rotatable balls, and the chuck by these balls causes the veneer to rotate around the balls, thereby correcting the slant of the veneer. Even though it is easy to do, it can be corrected without any problems.
