BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a veneer veneer for scarf-cutting both ends in the fiber direction of veneer veneer.

[0002]

2. Description of the Related Art Conventionally, plywood has been obtained by cutting a plurality of pieces of wood having the same thickness or different thicknesses, which have been cut from raw wood selected as a plywood applied material and cut to a required size, out of raw wood mainly made of southern wood. It is manufactured by stacking veneers. The veneer polished from the log of the plywood applied material is not the same size as the plywood due to the start of the cutting, the end of the cutting, the knots, and the decaying part, because the log is not cylindrical. In order to combine the boards in the fiber direction and join the veneers of the veneer to each other to make the size of the plywood, there is a so-called vertical flute method in which both ends of the veneer in the fiber direction are scarf cut and bonded with an adhesive or the like. . A veneer cutting method for this purpose is described in Japanese Utility Model Publication No. Sho 64-4481 in which a defective portion at the front and rear ends of the veneer in the transport direction is detected and cut to separate the veneer into an effective portion and a defective portion. There is such an apparatus (conventional example 1). This device is
A veneer veneer (hereinafter referred to as veneer), a veneer carry-in body for transporting the veneer veneer to the blade in the same direction as the fiber direction (hereinafter, referred to as a transport direction), a veneer veneer for carrying out the veneer after cutting, The diagonally enters the veneer veneer from the top of the veneer veneer at an angle, from above the transport path on the veneer carry-in side (hereinafter referred to as the entry side) to below the veneer transport path on the veneer carry-out side (hereinafter referred to as the exit side). A reciprocally operable blade for cutting, a receiving blade provided opposite to the blade, a veneer detector provided on the entrance side of the receiving blade, a tip between the veneer unloading body and the receiving blade, A rotatable opening / closing body having a rotation center on the exit side and a rotation center on the outgoing side, and a state in which the front end of the opening / closing body is turned up and in a standby state, the veneer of the veneer loading body is detected by the front end detection signal of the veneer detection device. Stop running, then reciprocate the blade to cut the veneer, and then lower the open / close body to make it stand by. To move the veneer, stop the traveling of the veneer carry-in body with the rear end detection signal of the veneer detection device, then reciprocate the blade to cut the veneer, and then turn the open / close body up and turn This is a veneer cutting apparatus having a control circuit for controlling to make it stand by, in which a plate holding member 6 provided with a piercing body 7 is provided on an entrance side. As a veneer cutting apparatus, an apparatus (conventional example 2) described in JP-B-47-29286 has also been proposed.

[0003]

However, in the apparatus of the prior art 1, since the cutting tool is provided with a slant for scarf cutting in order to obtain a wider bonding surface by cutting, the apparatus is formed by the lower surface of the cutting tool and the veneer. The space became narrow, and it was impossible to dispose the plate holding member in a state where the blade was close to the position where the blade cut the veneer. Therefore, even if the veneer is pressed by the plate holding member, the whole veneer cannot be entirely suppressed, and the veneer is cut with the waviness remaining on the veneer as shown in FIG. 4 (a). Becomes In addition, even if the plate holding member is reduced in size and is brought closer to the cutting position, the pressing force applied to the plate holding member is reduced, so that the undulation cannot be suppressed in the same manner. Even if adhesive is applied to the inclined surface of such a veneer and bonded to another scarf-cut veneer, a gap is easily formed in the bonding surface and the adhesive strength is weakened, and the bonding portion is not linear, The appearance was poor as seen from the fiber direction. On the other hand, in the device of Conventional Example 2, the veneer is sandwiched and cut by the veneer presser and veneer receiver on the output side of the receiving blade. Since it is provided so as to be movable in the direction of the cut portion of the veneer and interferes at a portion closer to the cut portion of the veneer, it cannot be held at a portion closer to the cut portion.

[0004]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a cutting device according to the present invention; (Example 1) The veneer cutting device according to the present invention is, as illustrated in FIG.
Numeral 3 is a blade composed of a rotary blade 3a and a rotary shaft 3b,
The rotary blade 3a, which is rotatable in the normal and reverse directions about the rotary shaft 3b by a known operating mechanism, has its rotary shaft 3b slightly inclined to the exit side with respect to the normal to the plate surface of the veneer. Since the working angle on the entry side is an acute angle with respect to the plate surface, and the rotary shaft 3b can reciprocate in the direction perpendicular to the transport direction A in the transport path of the veneer by a known feed mechanism,
The beginning and end of the veneer can be cut diagonally. That is, the rotary blade 3a waits at a position deviated from the veneer transport path in a direction perpendicular to the veneer transport direction A, and at this standby position, the left side facing the lower side in the veneer transport direction (the back in FIG. 1). Side) at the standby position, the end of the forward path
A signal is issued, and when the vehicle is at the standby position on the right side (the front side in FIG. 1), a return path disconnection end signal described later is issued. In addition, when the rotating direction of the rotary blade 3a moves from the standby position on the left side to the standby position on the right side, when the rotary blade 3a moves from the upper side in FIG. In the clockwise direction as viewed from above, the cutting edge at the forefront with respect to the traveling direction of the rotating shaft 3b rotates in the transport direction to cut the veneer. As a result, the working angle between the direction in which the veneer is cut and the transport direction becomes an acute angle, and the veneer can be cut while being pressed downward. Note that the inclination angle of the rotation shaft can be changed as appropriate. Reference numeral 4 denotes a receiving blade which is provided below the rotary blade 3a, and has a blade edge which is a lower surface of the blade edge of the rotary blade 3a and is slightly close to the rotation axis direction. The upper surface with respect to the transport passage is provided to support the lower plate surface of the veneer P and prevent the veneer from bending downward due to the cutting force of the rotary blade 3a.
6 is a veneer support member provided rotatably about a rotation shaft 5 perpendicular to the transport direction to the lower side, which is the upper and lower sides of the veneer transport path, on the exit side of the receiving blade 4. It is. A support portion 7 is attached to the tip of the veneer support member 6, and a first position shown by a solid line, where the support portion 7 comes into contact with the veneer by rotating the support blade 7, The part 7 is rotated between a second position indicated by a dotted line, which does not contact the veneer plate, and abuts on the cutting edge side surface of the receiving blade 4 on the output side. In the second position, the receiving blade 4 prevents dust, which is an unnecessary part of the veneer, from dropping between the receiving blade 4 and the support portion 7, but instead of the rotating shaft 5 as another embodiment. It is also possible to provide a mechanism that can move in the vertical direction and a cover that closes a space created when the robot descends.
As shown in the front view of FIG. 2A, the support section 7 has a triangular shape with a sharp edge on the surface perpendicular to the veneer transport direction in order to pierce the lower plate surface of the veneer. As shown in the perspective view of FIG. Then, as shown in the right side view of (A) of FIG. 2 (B), it is desirable that the long side 71 of the wave-shaped cutting edge is orthogonal to the veneer conveyance direction, and eliminates undulation without entering between veneer fibers. Finally, it can be clamped by the single-plate pressing member 8 while holding down. Numeral 8 is a veneer pressing member which is provided above the veneer transport passage of the veneer support member 6 and is formed of a rigid material having a flat end.
The veneer pressing member 8 has a third portion, shown by a solid line in FIG. 1, whose tip is very close to the supporting portion 7 so as to sandwich the veneer when the supporting portion 7 is at the first position. Position, and then when the support 7 is at the second position and the veneer is transported, it rises from the third position and waits for the veneer to pass, the fourth line shown by the dotted line Move between positions. The ends of the support portion 7 and the veneer pressing member 8 at the first and third positions are extremely close to each other, and the conveyed veneer is moved by the support portion 7 to the veneer veneer member 8 having high rigidity. It is pinched by being pressed. Reference numerals 1 and 9 denote veneer carry-in rolls and carry-out rolls for carrying in and out veneers to and from the cutting device, and start and stop of the traveling are controlled by a control circuit. Reference numeral 10 denotes a constantly rotating dust removing roller, which descends to the upper portion of the trailing waste at the rear end of the veneer left on the transport path, and rotates and drops when it comes into contact with the trailing waste. When this scrap removal roller is used, under the veneer conveyance path at the cutting position,
The support 7 can be provided in the space immediately below the cutting position without the need for a transport roller for driving the conveyor. Reference numeral 2 denotes a veneer detecting device, which is provided with known veneer detectors 2a to 2n provided on the entrance side of the rotary blade 3a at appropriate intervals so that a plurality of veneer detectors are perpendicular to the veneer transport direction. The swing of the detection arm 12 accompanying the displacement of each detection roller 11 is input to a control circuit by a limit switch or the like, and a front end and rear end detection signal is output.

The control circuit is configured as shown in FIG. That is, the normally open contact of each of the single-plate detectors 2a to 2n is connected to the OR circuit 20.
And connected to the AND circuit 21 in parallel. The output side of these AND circuits 21 is connected to an AND circuit 23 via a delay storage device 22 using a magnetic drum. This delay
The storage device 22 starts counting when the output signal of the AND circuit 21 becomes 1, and the cut position at the lower end of the veneer is slightly higher than the veneer position of the veneer detectors 2a to 2n depending on the conveyor speed. when required to be transported to the point
It is set so as to output to the AND circuit 23 with a delay of T1 . Similarly, the delay storage device 27 starts counting when the output signal of the AND circuit 21 becomes 1 through the NOT circuit 26, and the scheduled cutting position at the upper end of the veneer is determined by the veneer detectors 2a to 2a. The time T3 required to be transported from the position 2n to a position slightly better than the cutting position is delayed
The output is set to the AND circuit 32 . The OR circuit 31 input to the AND circuit 32 starts counting when the output signal of the AND circuit 21 becomes 1 through the NOT circuit 26, and is required to carry the allowable length of the partial crack of the veneer. An AND circuit 29 outputs a signal 1 when one output signal from the delay storage device 28 set to be output with a delay of time T2 and one output signal via the NOT circuit 26 of the AND circuit 21 are input. And the NOT circuit 30 connected to the OR circuit 20. When the leading edge cutting signal and the trailing edge cutting signal are input to the veneer forward path cutting operation 24 and veneer returning path cutting operation 33, the traveling of the veneer carry-in roll 1 and the carry-out roll 9 is stopped in conjunction with the control circuit. After the rotating shaft 3b of the rotating rotary blade 3a moves one way to cut the veneer, a signal indicating that the cutting of the veneer has been completed is transmitted at 25 and 34.

The first embodiment is provided as described above, and its operation will be described below. The rotary blade 3a is waiting at the standby position on the left as described above. When the veneer is not on the veneer transport path, the veneer detectors 2a to 2n output a 0 signal. In addition, the code | symbol of a single-plate detector when explaining an effect | action is 2a-2n in order of detection for convenience. First, in order to cut and form the tip of the veneer, the leading end of the veneer in the transport direction of the veneer conveyed by the veneer carry-in roller 1 reaches the position of the corresponding veneer detector 2a. Then, when it is detected, the single-plate detector 2a outputs 1 signal. Therefore, the signal 1 of the single-plate detector 2a is input to the AND circuit 21 .
The signals of the single-plate detectors 2b to 2n are input as 0.
The output of the AND circuit 21 does not satisfy the Runode AND conditions Ah 0
You. Therefore, the delay storage device 22 does not operate, and the AND circuit 2
The signal input to 3 is still 0, and the tip of the veneer is cut.
Not. Next, the rearmost end of the outgoing end of the veneer reaches the position of the corresponding veneer detector 2n, and when it is detected, the veneer detector 2n also outputs a signal of 1. Therefore, the signals of all the single-plate detectors 2a to 2n become 1, and the output of the AND circuit 21 is output.
Power is 1, delay line memory 22 is a signal 1 is inputted to the AND circuit 23 after the time course of operating T1, stands by at the standby position rotary blade 3 is left as described above, the return path cut
Since the end signal is input and the AND condition is satisfied, the output of the AND circuit 23 becomes 1, and the front end detection from the single-plate detection device 2 is performed.
A signal is output. In order to cut and form the tip of the veneer by the control circuit and the control circuit, the veneer loading roll 1 is used.
And the unloading roll 9 is stopped, the veneer supporting member 6 is turned forward to operate from the second position to the first position, and the veneer pressing member 8 is also moved forward from the fourth position to the third position by lowering. Later, the rotary blade 3 moves on the outward path to the right side to perform cutting, the front end debris is dropped by its own weight, and stands by at the right side position.
After being output to the circuit 32, the veneer support member 6 and the veneer pressing member 8 are respectively operated to retreat to the second position and the fourth position, the veneer carry-in roll 1 and the carry-out roll 9 travel again. Start. The rotary blade 3 at the right standby position is the rear end of the veneer.
Waiting for disconnection.

If a crack less than the permissible amount occurs partially after the cutting edge of the veneer, the output of the AND circuit 21 becomes 0 and the delay memory 28 starts counting.
When the signal 8 outputs the signal 1, the AND circuit 21 outputs the signal 1 again. Therefore, the output of the AND circuit 29 remains 0, and the single-plate detection device 2 does not output the rear end detection signal. Does not reach. The cutting of the rear end portion of the veneer includes a case where the veneer has a crack exceeding an allowable amount and a case where the veneer has passed within the crack determination time T2. First, when the entrance edge of the veneer reaches the position of the corresponding veneer detector 2a, the veneer detector 2a changes from a signal of 1 to a signal of 0, and the AND circuit 21
And the AND condition is released, the output of the AND circuit 21 becomes 0, and the signal 1 is output by the NOT circuit 26 to the delay storage device 2.
Input to 7, 28 to start counting. Delay storage device 2
When the set time T2 of 8 has passed, the signal of the single-plate detector 2a is 0, so that the rear end cutting position is determined, and the AND circuit 2
The output of 9 becomes signal 1. When the veneer passes within the crack determination time T2, the OR circuit 20 outputs a signal 0 and outputs 1 via the NOT circuit 30 . And AND
The output of the OR circuit 31 becomes a signal 1 by inputting either the output signal 1 of the circuit 29 or the output signal 1 of the NOT circuit 30. The delay storage device 27 sets a time T3 required for a portion where the signal of the veneer detector 2a becomes 0 due to the passage of the veneer to be conveyed to a position slightly higher than the cutting position. When the time T3 has elapsed, the AND circuit 32 outputs the signal 1 and outputs the rear end detection signal in response to the input of the forward path disconnection end signal 25 and the signal of the OR signal 31, so that the single-sheet carry-in roll 1 and the carry-out roll 9 are output. Stop. Then, in order to cut and form the rear end of the veneer, the veneer support member 6 is turned to
Then, the veneer is moved to the position shown by the solid line and the veneer pressing member 8 is lowered to hold the veneer from both front and back surfaces. Next, the rotary blade 3a at the right standby position moves and cuts while rotating on the return path. When the movement of the return path is completed while the rotary blade 3a is cutting, the return path cut end signal 34 is output.
After being output to the AND circuit 23 and preparing to cut the next veneer, and after the veneer support member 6 and the veneer pressing member 8 have been moved to the positions indicated by the dotted lines, the veneer is next transferred by the unloading roll 9. It is guided to the process, and then the dust removing roller 10 descends and comes into contact with the trailing waste, so that the trailing waste is removed from the transport path to the lower side.

In this cutting, the vicinity of the lower side of the cut portion of the veneer is fixed flat by the tip of the veneer support member 6 and the veneer pressing member 8, so that the veneer is warped or undulated. The whole is a uniform cut surface as shown in FIG. In particular, in the embodiment, since the pressing portion which is the tip of the veneer pressing member 8 has a flat surface, the veneer is sandwiched between the tip of the veneer supporting member 6 and the veneer. It follows the flat surface of the pressing member 8, and it is easier to be flat. In addition, since the veneer support member 6 and the veneer pressing member 8 have a rigid structure, when the veneer is sandwiched, the two members hardly deform, and the veneer can be reliably flattened. You can. Furthermore, since the tip of the veneer support member 6 has a narrow shape in the veneer transport direction, the veneer can be clamped at a position as close as possible to the veneer cutting point from the lower side in the transport direction. Thus, the cut surface can be more effectively made uniform. Further, in the above-described embodiment, since the veneer is sequentially cut from one end to the other end by the rotating blade 3a rotating the veneer, undulation is more likely to occur due to the ironing action of the rotating blade 3a. The board can be cut. According to the above embodiment, the veneer support member 6 is rotatable about the rotation shaft 5, and when the veneer cannot be clamped, the veneer 4 is rotated.
The front end of the veneer support member 6 is located below the veneer passing line, so that the veneer does not hinder the veneer passage. To fall.

The receiving blade 4 has an anvil 4a at its tip for receiving a cutting force of the rectilinear blade 3c, and supports the lower plate surface of the veneer P to support the lower plate. It is intended that the cutting force of the rectilinear blade 3c completely acts on the veneer. 6 is provided on the upper side of the veneer conveyance path on the exit side of the receiving blade 4, and the supporting portion 7 at the tip is the exit side of the receiving blade 4 due to the movement thereof and is indicated by a solid line that can contact the veneer. This is a known operating mechanism that is movable between a position 1 and a second position indicated by a dotted line, which retreats upward so that the support portion 7 does not contact the veneer. Reference numeral 8 denotes a third surface which is opposed to the veneer support member 6 and which is indicated by a solid line whose tip is extremely close to the support portion 7 so as to sandwich the veneer when the support portion 7 is at the first position. , And when the veneer is conveyed, it is lowered from the third position and waits for the veneer to pass through. The veneer pressure is movable between a fourth position indicated by a dotted line and a veneer. The pressing portion at the tip is a member having a flat shape and rigidity. The support portion 7 and the veneer pressing member 8 at the first and third positions have their tips extremely close to each other, and the transported veneer is moved by the supporting portion 7 to the rigid veneer pressing member 8. It is pinched by being pressed. The veneer unloading body 9 ′ is a transfer device that sucks the cut veneer P and moves it from the transfer path to the next process. Reference numeral 13 denotes a veneer presser, and if the straight blade 3c is used, the fiber at the rear end of the veneer tends to come off. The operation mechanism according to the above configuration is the same as that of the first embodiment. Further, it is also possible to hold not only at the time of cutting the rear end but also at the time of cutting the front end.

[0012]

According to the cutting apparatus constructed as in the first and second embodiments, the bending of the veneer caused by the cutting force acting in the direction perpendicular to the veneer conveyance path is clamped by the veneer pressing member.
