Description

[Detailed description of the device] [Industrial applications]

The present invention is intended for a long continuous veneer veneer obtained by turning from raw wood with veneer lace, and the material of the veneer veneer is finely pierced by a piercing rotary member having a sharp protrusion portion while being orthogonal to the fiber direction. The present invention relates to a veneer tenderizer whose material is corrected by being transported to a veneer tenderizer.

[Prior art]

As conventional devices of this kind, for example, Japanese Patent Publication No. 50-5247, Japanese Utility Model Publication No. 52-31333, Japanese Patent Publication No. 52-2.
No. 7,206, Japanese Patent Publication No. 37-2787, etc. are known. All of these conventional devices adjust the pressing force at the left and right ends of the upper pressure roll among the pressure rolls facing each other to the left and right tenders according to the meandering state of the veneer veneer. It was designed to restore the meandering of veneer veneer by differentiating the rising effect (extension amount, prevention of cracking).

[Means for Solving the Problems]

The present invention is intended to solve the above-mentioned problems, and in a veneer tenderizer in which a piercing rotary body having a large number of protrusions on the outer circumference is faced to the upper part of a rubber roll in the same axis, the left and right axial ends of the piercing rotary body The right and left screw feeding mechanisms are separately attached to the support body that supports the parts, and the left and right shaft ends of the piercing rotary body facing the rubber roll are horizontally and longitudinally aligned in the conveying direction of the veneer veneer. It is configured to be able to turn.

【Example】

As shown in FIGS. 1 and 2, an embodiment of the present invention is such that a piercing rotary member 1 having a sharp protrusion 1a on its outer periphery is rotatably supported by a support member 3 and an axial line is provided on an upper portion of a rubber roll 2. In the veneer tenderizer having the same structure, the support 3 is further supported by the eye beams 7 and the like on both sides by the movable frames 8a and 8b.
Further, one side of the movable frames 8a, 8b with respect to the conveying direction is a link mechanism 10a, 10b and an air cylinder 11a, 11b for pressing and fixing at a facing interval between the piercing rotating body 1 and the rubber roll 2 set by an interval adjusting screw 9. And the other side of the movable frames 8a and 8b in the transport direction is axially mounted on the right screw feed mechanism 4a and the left screw feed mechanism 4b via pins 13a and 13b, respectively. Has been done. Furthermore, the feed mechanisms 4a and 4b are connected to the uniaxial handle device 5 via the worm gears 14a and 14b, etc., and the left and right turning angles of the piercing rotary body 1 facing the rubber roll 2 are set, that is, the piercing rotation. The left and right shaft ends of the body 1 are configured to be horizontally adjustable in the conveying direction of the veneer veneer 6 and centered in the front-rear direction so as to be adjustable. That is, according to the present invention, by rotating the handle device 5 to the right or left as shown in FIG. 1, the support body 3 supporting the piercing rotary body 1 and the eye beam 7 are pivoted to the left and right as shown in FIG. The piercing rotor 1 and the rubber roll 2 are rotatably opposed to each other so that the piercing rotor 1 and the rubber roll 2 are not laterally parallel to each other.
A slight mechanical unbalance on the left and right of the veneer tenderizer itself, for example, an accumulated error of the left and right transport amounts caused by parallel errors during assembly, and a slight material unbalance on the left and right of the veneer veneer itself to be corrected, For example, hard and soft, uneven thickness,
Due to the accumulated error of the left and right conveyance amount due to the number of cracks, etc., the conveyance meandering phenomenon of veneer veneer that is meandering to one side and the conveyance is twisted and bent gradually, This is constructed so that it can be restored by turning. Incidentally, the present invention is not limited to the means for adjusting the turning angle in the center distribution of the above-mentioned embodiment, and in order to turn the supporting body 3, the left and right feeding mechanisms 4a and 4b are separately mounted.
Needless to say, it is possible to fix the one side of the veneer veneer by fixing the one side or to abolish the one side and to correct the meandering phenomenon of the veneer veneer of this type by adjusting the turning angle of only one side. In some cases, the movement of the edge line of the veneer veneer during the straightening process may be detected by an edge positioner or the like, and the detection signal may be transmitted to a servo motor or the like mounted on the handle device 5 to fully automatically It is also possible to correct the meandering of veneer veneer during the correction process.

[Effect of device]

As described above, the present invention is a veneer tenderizer in which a piercing rotary body having a large number of protrusions on the outer circumference is faced to the upper part of a rubber roll with the same axis, and the left and right axial ends of the piercing rotary body are supported. A right screw feed mechanism and a left screw feed mechanism are separately mounted on the support so that the left and right shaft ends of the piercing rotary body facing the rubber roll can be swung horizontally and anteroposteriorly in the conveying direction of the veneer veneer. Therefore, according to the present invention, repair of meandering due to accumulated error of left and right conveyance amount due to slight left and right mechanical unbalance of the veneer tenderizer itself, and right and left of the veneer veneer itself to be corrected To correct the meandering due to the accumulated error of the left and right conveyance amount due to the slight material unbalance of the, the shaft end of the piercing rotary body is adjusted to be swiveled horizontally and forward and backward in the conveyance direction of the veneer veneer. In addition to being able to directly change the conveying direction of the veneer veneer, the left and right tender effects of the veneer veneer (extension amount, prevention of spillage) are not only uniform, but also the restoration speed is the same as the conventional device. By adjusting the vertical pressing force for cracking a veneer to the left and right individually, the meandering is repaired due to the difference in the left and right extension amount due to the cracking. Since the direction can be changed directly by the turning of the piercing rotary body, the operation is quick, and it is possible to immediately respond to the meandering of veneer veneer, and as a result, work can be performed at high speed. It can be played.
