Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a device that automatically loads half-cut veneers of half the specified length of plywood onto a pile, and specifically The clipper that cuts the veneer is directly connected to the veneer lace veneer cutting line, and the half-cut veneers that are transported at high speed can be loaded onto the pile with the edges aligned without any trouble, and the transportation of the pile provides a loading device for half-cut veneers that can be made into piles suitable for the next process.

(Prior art) Recently, as the quality of raw wood has deteriorated, the quality of the veneer cut by veneer lace as the core board of plywood has also deteriorated. Since the heart is often damaged, it is now often cut into half veneers. When stacking half-cut veneers that have been cut and transported at high speed onto a pile, the conventional method has been to arrange a sticking or suction conveyor following the clipper, and use the area below these as a pile. When a half-cut veneer suspended and conveyed by a sticking or suction conveyor is dropped downward, a bar-shaped body that moves up and down, a bar-shaped body that is inclined so as to cross the suspended conveyance path, or an endless conveyor is used. It is being

(Problem to be solved) However, in the case of the former type of bar-shaped body that moves up and down, it is necessary to increase the dropping speed, and there are disadvantages such as damage to the veneer due to impact. In the case of a bar-shaped body or an endless conveyor, although the impact of detachment is small, the falling position is not stable and the frictional resistance between the veneers is large, so there is a problem that the pile is often misaligned. Furthermore, it is necessary to use a base plate on which the half-cut veneers are piled up in one pile, and this base plate has a problem in that the workability of transporting by a forklift is poor.

(Means and effects for solving the problem) This device was developed to solve the above problem, and is designed so that a feeding force in the direction opposite to the conveying direction of the pricking conveyor acts below the pricking conveyor. It is formed by rollers that are somewhat inclined with respect to the conveying direction of the pricking conveyor, and the roller conveyor is arranged in a direction roughly perpendicular to the conveying direction of the pricking conveyor, and the stacking position is provided at the end of the roller conveyor. Therefore, when the half-cut veneer is released from the sticking conveyor and is received by the roller conveyor, the frictional resistance between the half-cut veneer and the rotating roller is small.
Therefore, the half-cut veneer can slide freely and be placed on the roller conveyor without any trouble, and its posture can be corrected during conveyance, so that it can be stacked neatly on the pile pile. In addition, the configuration in which the rollers at the falling position are tilted can apply a braking effect to the placed veneer in the opposite direction to the advancing direction, stabilizing the falling position and regulating the position of the edge. Edge-to-edge deposition can be achieved. In addition, a single-core base plate is used as the base plate on which half-cut veneers are deposited, and the base plate is moved to deposit two piles on the base plate, which is commonly used in other manufacturing processes in the plywood industry. It is possible to commonly use the existing single-core base plate, and there is no need to specially manufacture a new base plate for stacking half-cut veneers, which is advantageous in terms of base plate management. Furthermore, when transporting piles using a forklift, the size of the half-cut veneer pile base plate, which is approximately half the size of a single core base plate, requires the forklift's fork lift to match the size of the base plate. It is necessary to change the position each time it is transported, and then to change it back to its normal position after transport is complete.
In order to transport the same number of piles, twice the number of transports is required, but in the configuration of the present invention, the above-mentioned drawbacks are solved and workability can be improved. Also,
The dryer used in the next drying process is generally designed and constructed with a width that allows two pieces of plywood with a specified length to be inserted at the same time, and the dryer is designed and constructed with a width that allows for the insertion of two veneers of specified length at the same time. The surrounding facilities have also adapted to the dimensions of the base plate for a single core, which is the specified size, and the half-cut veneer is used as a single core as in the configuration of the present application.
By depositing two piles on the base plate for single cores, it is possible to supply piles suitable for the drying process without requiring modification of surrounding facilities as described above.

(Embodiment) To explain this invention with an embodiment shown in the drawings, a conveyor 1 is connected to a veneer lace veneer cutting line, conveys the veneer A at high speed in a direction perpendicular to its fibers, and rotates the veneer A for example. Clipper 2 of formula etc.
It is to be sent to The veneer detector 3 detects the boundary line between the defective part and the valid part of the veneer A, and also integrates the length of the veneer A that passes through it. It sends a detection signal when the size of the veneer of length 2) is reached, and each detection signal is transmitted to the operating mechanism 5 of the clipper 2 via a timer 4, and the detected position is transmitted to the clipper 2. It twists and gets cut. Defective veneers cut and separated by the clipper 2 are removed from the conveyance path from the end of the clipper conveyor 6, and sized veneers with end lengths that are less than the size of the half-cut veneer B are removed from the clipper conveyor 6. It is removed from the end portion out of the conveyance path, or is pricked and transported by a pricking conveyor, which will be described later, and deposited at an appropriate position.

The pricking conveyor 7 has a large number of needle-like bodies N attached to the surface of the endless strip, and the needle-like bodies N are stuck to the surface of the veneer and conveyed in a suspended manner. It extends upward from the distal end to the rear, and its downward running path is used as a pricking conveyance path. The pricking conveyor 7 pricks and conveys the front end of the half-cut veneer B, for example.
A strip of threaded endless belt 7a and two threaded threaded endless strips 7b whose intermediate or rear end portions are threaded and conveyed are arranged side by side,
These endless strips 7a and 7b are driven by a drive mechanism 8 at substantially the same speed as the clipper conveyor 6, and the conveyance surface below thereof is used as a needle conveyance path for the half-cut veneer B. The stabbing of the half-cut veneer B by each of the endless stabbing bands 7a and 7b is carried out by a pressing body 9 for the front end and a pressing body 10 for the intermediate or rear end, which are provided near the front ends of these. An operating mechanism 11 is attached to the pushing body 9, and an operating mechanism 12 is attached to the pushing body 10, and these operating mechanisms 11 and 12 move the pushing bodies 9 and 10 between the standby position indicated by the solid line in FIG. It moves up and down between the action position where the back surface of the endless band is pressed as shown. Then, the detection signal of the front end of the half-cut veneer B by the veneer detector 3 is transmitted to the actuating mechanism 11 via the timer 13, and the front end of the half-cut veneer B cut by the clipper 2 is directly below the pressing body 9. When reaching the point, the back side of the stuck endless band 7a is pressed to stick the needle-shaped body N to the front end, and the detection signal of the middle part or the rear end of the half-cut veneer B by the veneer detector 3 is sent to the timer. 14 to the actuating mechanism 12 and actuates the pressing body 10 to stick the needle-like body N of the stuck endless band 7b to the middle part or the rear end, and half-cut by both the stuck endless bands 7a and 7b. Board B is transported in a suspended state.

At an appropriate position on the suspension conveyance path of each stabbed endless belt 7a, 7b, there is a front end portion for passing diagonally across the suspension conveyance path of each stabbed endless belt in the direction of travel and freeing it from being stuck by the needle-shaped body N. A detachment means 15 for the middle section or the rear end section and a detachment means 16 for the intermediate section or rear end section are provided. Each detachment means 15,
Reference numeral 16 is, for example, a fixed bar-like body or a running endless band, and is arranged so that the front end and the middle or rear end of the half-cut veneer B can be released from the needle-like bodies N at almost the same time. In addition, when pricking and conveying not only half-cut veneer B but also sized veneers and stacking them by the staking conveyor, the stubbed endless belt for the sized veneer is placed on the stubbed endless belts 7a and 7b. They are arranged side by side, and the sized veneers are separated and stacked at an appropriate position different from the removal position of the half-cut veneer B.

The roller conveyor 17 is made up of a large number of rollers, and has a conveyance path in a direction substantially perpendicular to the conveying direction F of the pricking conveyor 7 below the detachment means 15 and 16 of the pricking conveyor 7, so that the roller conveyor 17 is free from the pricking conveyor 7. It receives the falling half-cut veneer B and transports it in the direction of its fibers, and each roller is driven by a drive mechanism 1.
Rotationally driven by 8. Each roller immediately below the pricking conveyor 7 that receives the half-cut veneer B from the pricking conveyor 7 is provided so that its axis is somewhat inclined with respect to the conveyance direction F of the pricking conveyor 7. Since each roller of the roller conveyor 17 is provided so as to be inclined, as shown in FIG. This feeding force F'' in the opposite direction applies a braking action to the half-cut veneer B that has fallen onto the roller conveyor 17 in the opposite direction to its traveling direction, stabilizing the placement position, and also Since is rotating, the frictional resistance between the half-cut veneer B and the roller surface is small, so the half-cut veneer B can freely slide on the roller conveyor 17, and one end edge of the half-cut veneer B can be moved to one end of the roller conveyor 17. By moving it toward the ruler plate 19 provided on the side, the position of the edge can be regulated.

At the end of the roller conveyor 17 in the conveying direction, a single-core base plate 20 is arranged so that the half-cut veneers B can be deposited on two piles B' and B''.The longitudinal direction of the base plate 20 is The base plate 20 is arranged so as to be substantially perpendicular to the conveying direction at the end of the roller conveyor 17, and is provided with a moving means 23 consisting of a conveyor 21 (for example, a roller conveyor) and its drive mechanism 22, so that the base plate 20 can be moved to the end of the roller conveyor 17. Then, when stacking the half-cut veneer B on the base plate 20, the base plate 20 is stopped at the position shown by the solid line in FIGS. The veneer B is loaded onto the pile B', then the base plate 20 is moved to the position shown by the dotted line, and the veneer B is loaded onto the pile B''. The half-cut veneer B transported by the roller conveyor 17 is loaded onto the base plate 20 as in the embodiment.
A conveyor 21 for moving is provided on the elevator 24, and the elevator 24 is lowered every time one or more half-cut veneers B are loaded onto the base plate 20, or
Alternatively, the distal end of the roller conveyor 17 may be provided so as to be movable up and down. Stopper 2 attached to elevator 24
