Description

Detailed Description of the Invention (a) Industrial Application Field The present invention is used in the field of plywood manufacturing, and in particular, the length in the fiber direction cut by a veneer lace, veneer slicer, etc. The main target is a long veneer veneer that is long, narrow in width perpendicular to the fiber direction, and thin, and the end surface of the long day veneer is precisely perpendicular to the veneer cutting line of the cross-cutting machine. In order to do this, in connection with the intermittent conveying operation of the cross-cutting machine, the long veneer in the conveying process is repeatedly lifted and moved laterally several times to automatically align the butt sides. This invention relates to an improvement in a method and device for aligning the ends of long veneers in a board crosscutting machine.

(b) Prior Art Regarding this type of end alignment device for veneer veneers, which is a prior art, there is a device for aligning veneer veneers during the conveyance process, for example, as disclosed in Japanese Patent Publication No. 55-7121, automatic alignment device for veneer veneers, etc. It is possible to apply the desired driving force in both the direction of the fibers, which is the ruler direction, and then in the direction perpendicular to the fiber direction, which is the ruler direction, and the direction of the fibers, which is the conveyance direction, by lightly pinching the paper from above and below. "A device for aligning the edge of veneer veneer using rollers" and a commonly used "diagonal conveyor device" are well-known. The applicable range of veneer veneers is relatively thick, long in the fiber direction, and wide in the orthogonal direction.For example, the core board of plywood products is the thick, wide short board used for the middle board. Somehow it was applied to veneer veneers in that range because only the boards could barely withstand the aligning action of the powerful thrust of the spiral rollers and diagonal conveyors.

(c) 1. Problems that the invention seeks to solve As mentioned above, the conventional veneer veneer end alignment device has the disadvantage that it can only be applied to relatively thick, wide and short veneers; It is thin, long in the fiber direction, and short in the orthogonal direction, for example, used for the top, back, or middle boards of plywood products. 200χ
In the case of long and narrow veneers, the area near the end of the wood may buckle due to the pressing force of the spiral roller.
1. Even if you try to turn the side opposite to the ruler to the left or right for alignment, the long veneer has no stiffness, so it just bends near the middle, which is a serious defect and prevents the desired alignment. It was an attempt to erase what was there.

(b) Means for solving the problem The method of the present invention is directed to the method of the present invention. In order to make the end surface of the veneer exactly orthogonal to the veneer cutting and joining line of the cross-splitting machine, each long veneer is intermittently conveyed in a direction perpendicular to the fiber direction. It consists of a method of aligning the end of a long veneer, in which the end surface of the long veneer is brought into close contact with the ruler surface by repeatedly moving this in the direction of the fibers several times. , and the device invention of the present invention is 8) a multi-row conveyor that intermittently conveys individual long veneers in a direction perpendicular to the fiber direction in connection with the production operation of a cross-cutting machine; 1)) a conveyor of the conveyor; C) rotary rulers arranged in parallel on one side of the conveyor perpendicular to the veneer cutting joining line of the horizontal stripping machine; long lengths as all structural requirements; 4, which is a wood end alignment device for veneer
To explain the operation in detail with reference to the drawings, firstly, the present invention has a top plate 1.
In a known horizontal stripping machine 1 that produces long stripped veneers that will become back plates or middle plates, individual long strips are intermittently conveyed by a multi-row conveyor 2 in a direction orthogonal to the fiber direction. Single board 3a
, 3b', when the conveyance operation of the conveyor 2 is stopped, which is intermittently repeated during the veneer cutting operation and the veneer joining operation of the horizontal stripping machine 1, the normal conveyance level, that is, the above-mentioned Slightly longer veneers 3a, 3b' than the transport level of the conveyor 2! i=While lifting, the fiber direction is repeatedly moved several times in the direction of all the fibers, and the alignment operation is repeated several times until the end surface is in close contact with the ruler surface, that is, the ruler surface of the rotary ruler 4. The individual long veneers 68, 3 are long in length, narrow in width in the direction perpendicular to the fiber direction, and thin in thickness.
bi is the main target, and is related to the intermittent conveyance operation of the cross-splitting +M1 so that the end face is exactly orthogonal to the veneer cutting joint line 5 of the cross-splitting machine 1 when the long veneers 3a, 3b are not conveyed. Then, the long veneers 3a and 3b' are repeatedly lifted up several times during the suspension of conveyance and moved laterally in the direction of the ruler, thereby safely and reliably performing the automatic butt end alignment operation.

(f) Example Attachment 1 illustrating the embodiment of the device invention of this research
Describing the configuration in detail with reference to the drawings, the present invention first relates to the production operation of the horizontal stripping machine 1, that is, [)11 the horizontal stripping machine 1]
In connection with the veneer cutting operation and veneer joining operation, the individual long veneers 3a.

Conveyors 2 that sequentially and intermittently transport the fibers in a direction orthogonal to the fiber direction are installed in multiple rows.

The conveyor 2 is equipped with an intermittent drive device such as an electromagnetic clutch brake so that the conveyor 2 stops its conveying operation when the horizontal stripping machine 1 is in the veneer cutting operation or the veneer joining operation, and then restarts the conveying operation once it is finished. The conveyance operation is automatically controlled by the following. Between the rows of the conveyors 2, several rotating members 6 of different diameters are arranged in multiple rows. The rotating member 6 of different diameters is, for example, a rectangular square pipe as shown in the figure, or a blade-shaped member such as a flat iron member with rotating shafts attached to both ends. If the rotating member has a long rotation radius and has a total length in one direction, and the surface with the long rotation radius emerges from the upper surface as it rotates, the conveyor 20
It is configured so that it protrudes slightly above the normal conveyance level, and when the surface with a short rotation radius emerges from the top surface due to the rotation of the conveyor 2, it retracts slightly below the normal conveyance level of the conveyor 2. It is something. Then, if the different diameter rotating member 6 is activated at a rotation speed of about 120 times per minute by an intermittent drive device such as an electromagnetic clutch brake installed separately, the elongated veneer 3a mounted on the conveyor 2, 3b is
While being lifted several times, it is moved laterally, including turning left and right, to the side of the rotary ruler 4, which is arranged in parallel on one side of the conveyor 2, perpendicular to the veneer cutting and joining line 5 of the horizontal stripping machine 1. , whose end surface is brought into close contact with the ruler surface. It should be noted that this butt end alignment operation is performed during the conveyance downtime associated with one veneer cutting and joining operation of the side splinter 1, which usually lasts about 1.5 seconds. The long Qi board 3 whose end surface has been aligned by the conveyance operation of the conveyor 2 which is restarted when the operation is completed 'fct'. a, 3
b is safely and reliably delivered to the horizontal stripping machine 1.

(G) Effects of the Invention Since the present invention has the structure and operation as described above, it is a prior art technique that is similar to that of the prior art. A veneer veneer made by installing spiral rollers in parallel to a ruler conveyor so that the desired driving force can be applied in both directions orthogonal to the fiber direction (fiber direction, then ruler direction, and transport). The present invention eliminates the difficulty of the butt end alignment function for veneer shapes, where the commonly used "diagonal conveyor device" and the "end alignment device" have been applied only to thick, wide, and short veneers. In some cases, a long veneer that is long in the fiber direction, narrow in the direction orthogonal to the fiber direction, and thin and serves as the top, back, or middle board of a plywood product is placed near the butt end when aligning the end of the long veneer. When excessive pressure is applied to the wood (
It is possible to avoid the occurrence of buckling phenomenon in the vicinity, and the lateral movement of the long veneer with respect to the ruler surface is also performed by repeated alignment operations of rotating members of different diameters distributed in multiple rows, so that the long veneer can be It has achieved great results, such as being able to safely and smoothly rotate the side opposite to the ruler from side to side when aligning the veneers.
