Description

Detailed Description of the Invention (-1') Industrial Field of Use The present invention is directed to cutting edge veneers cut from logs using veneer lace, which are discontinuous or have many defects in the material. The veneer lace is divided into left and right sides by a cut made by a scoring knife placed in the center of the veneer lace to form a core plate with a short fiber direction.
In addition, for long veneers that are continuous following the end length veneer or have only a slight defect in the material, the notch of the scoring knife is pulled up to create an original board with a long fiber direction, and the end length veneer and the long length veneer are The present invention relates to an automatic processing method for the vicinity of the creasing end in a direct veneer processing process, in which shaku veneer boards are continuously cut and stacked in a series of processes.

0) Prior Art A discontinuous veneer with many defects in the material, which is divided by a conventional scoring knife of this kind, and a continuous veneer which is not divided by the scribing knife following the end veneer. Or, in the direct connection veneer processing process with long veneers that have only slight defects in the material, the end length veneer and the long veneer are cut and stacked in the central part of the veneer lace. When the cutting depth of the installed scoring knife is raised and the production shifts from end length veneer production to long length veneer production, the actual veneer cutting is suspended, for example, veneer lace. The feed of the cutting knife attached to the joint is stopped and the veneer in the cutting process is naturally separated, and the end length veneer of the preceding cutting veneer and the long veneer of the succeeding cutting veneer are separated. The end length veneers of the preceding cutting veneers are delivered to the tray conveyor of the core board processing line, and the long veneers of the following veneers are rolled into rolls by the glue-ring machine of the original board processing line. It was rolled up and processed separately, and these conventional techniques were developed, for example, in 1973.
It is disclosed in No. 15319, a veneer supply device for a dryer, etc.

In addition, after the end length veneer and long veneer are transferred directly from the veneer lace onto a tray conveyor in a processing line where core boards and original boards coexist, they are sorted respectively at the downstream stage of the tray conveyor. There is also a method of performing a cutting process, and these conventional techniques are also disclosed in, for example, Japanese Patent Laid-Open No. 59-20608, a tray conveyor device for veneer processing.

C\) Problems to be Solved by the Invention Among the above-mentioned conventional techniques, the former method involves delivering the end length veneer to a tray conveyor, and winding the long veneer into a roll using a reeling machine for processing. It was necessary to temporarily stop the veneer lace cutting work, wait for the natural separation of the end length veneer and long length veneer, and restart it each time while manually sorting the work, resulting in poor work efficiency and productivity. It is economically disadvantageous because it requires two types of large-scale processing equipment, such as a tray conveyor and a reeling machine, which have completely different configurations; The processing method involves a mixture of core plates with short fibers and original plates with long fibers, making it extremely difficult to process them automatically, and in practice, this has to be done manually by workers, so production is slow. It was also inefficient, requiring a large number of personnel.

Therefore, in order to eliminate the drawbacks of the above-mentioned conventional techniques, the present invention has been developed to remove the cut veneer by the creasing knife in conjunction with the lifting operation of the creasing knife when transitioning from the production of end length veneers to the production of long veneers. The vicinity of the crease end where the notch of the central crease disappears is automatically detected in the subsequent cutting process, and from this crease end vicinity the pre-cut veneer, that is, the edge length veneer that will become the core board, and the subsequent cut veneer, That is, the processing method has been greatly improved so that the veneer is automatically divided and sorted into long veneers that become original plates.

(g) Means for solving the problem The present invention automatically detects the vicinity of the creasing end where the crease cut in the center of the cut veneer by the creasing knife disappears, and starts from this vicinity the pre-cut veneer. This is an automatic processing method near the creasing end in a direct veneer processing process consisting of the following three steps a, b, and c, in order to automatically divide and sort subsequent cut veneers.

a) The first step of automatically applying paint near the creasing end of the cut veneer in conjunction with the lifting operation of the creasing knife placed in the center of the veneer lace.

b) Detecting the paint applied near the marking end of the cut veneer in the first step and automatically dividing the cut veneer into a preceding cutting veneer and a subsequent cutting veneer from near the marking end. The second step is to divide it into two parts.

C) A third step in which the preceding cut veneers separated in the second step are automatically sorted to the core plate processing line, and the subsequent cut veneers are automatically sorted to the original plate processing line.

(E) Function The operation of automatically applying paint near the marked end of the cut veneer in the first step is, for example, a fluorescent paint whose presence can be detected photoelectrically in the subsequent cutting step. In conjunction with the lifting operation of the scoring knife, a spray gun or the like may be used to automatically spray the area near the scoring end where the scoring cut has disappeared on the cut veneer, using a spray gun or the like at an appropriate time. An operation that automatically detects paint applied near the marking end of a cut veneer during the process, and automatically divides the cut veneer into the preceding cut veneer and the subsequent cut veneer from the detected location. For example, paint is detected by a paint detector such as a photoelectric switch installed on the conveyor for the subsequent cutting process, and the veneer clipper is controlled by a control command with an appropriate time limit based on the detection signal from the paint detector. By activating the , it is possible to automatically divide the veneer from the detection point into the preceding cut veneer, that is, the end length veneer that will be used as the core board, and the subsequent cut veneer, that is, the long veneer that will be used as the original board. Furthermore, the operation of automatically sorting end length veneers and long length veneers in the third step is, for example, when a detection signal from the paint detector is sent to a veneer divider connected to the veneer clipper. By activating this by a control command with an appropriate time limit, the end length veneer is automatically sent to the core board processing line at the lower part of the rear stage, and the long veneer is automatically sent to the original board processing line at the upper part of the rear stage. It is something that can be sorted.

〜Example A direct connection veneer processing process in which a veneer lace, a veneer clipper, and a veneer divider are directly connected by a tray conveyor will be described in detail as an example of the implementation of the present invention. A scoring knife 5 equipped with an elevating mechanism 4 such as an air cylinder, which can move up and down, is disposed in the center of the upper turret 3a of the veneer lace 2 that cuts the raw wood 1 so as to cut the log 1, and the cutting knife 5 of the lower frustum 3b 6 and a rotary body 7 such as a roller bar or a nose bar etc., and a spray gun 10 that sprays a paint 9 such as a fluorescent paint onto the upper surface of the cut veneer 8 which is cut and discharged while rotating the raw wood 1, is connected to the upper turret 3a. Place it near the bottom of. Furthermore, when the scoring knife 5 is pulled upward by the lifting mechanism 4 and the cutting operation of scoring the cut veneer 8 is stopped, the control signal that activated the lifting mechanism 4 is controlled to be given an appropriate time limit. is transmitted as a control command signal for the spray gun 10 from the device 11,
In the vicinity of the marked end of the cut veneer 8 during the cutting process, for example, as shown in FIG. The first step is configured to automatically apply the paint 9 to one or several locations in synchronization with the cutting speed of the plate 8.

The preceding cut veneer consisting of the end length veneer group 16 and the subsequent cut veneer consisting of the elongated veneer group 17 are cut from an appropriate location near the end of the cut veneer 8, for example, on the X-X line or the Y-Y line. A second step is formed to automatically divide the veneer into cut veneers. In addition, in the figure, 27 is a second cutter for post-cutting for cutting the cut veneer 8 into core plates 8a, 8b or original plate 8f, 28 is its second drive mechanism, 29a, 29

In other words, it is an automatic processing method near the creasing terminal in the direct veneer processing process, which automatically divides and sorts the veneer into long veneers that will become the original board, so it is highly efficient with a minimum number of personnel. Continuous processing work can be carried out in a series of processes, which eliminates the interruption of work caused by conventional technology and the reduction in work efficiency and productivity due to manual work. This invention is extremely effective in its implementation, as it completely eliminates the uneconomical nature of processing equipment.
