Field of the Invention The present invention mainly relates to a continuous veneer veneer (hereinafter referred to as a veneer) which is carried in by a carry-in mechanism such as a conveyer, which is successively reduced in length to a fixed length. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a veneer cutting apparatus and a veneer cutting method for cutting a veneer with a dimension.

[0002]

2. Description of the Related Art Conventionally, as described in JP-B-53-8387, at least a single veneer (hereinafter referred to as "continuous veneer") conveyed by a conveyor is cut into a fixed length. A pair of rotating rolls (hereinafter, referred to as rolls) for nipping and transporting the plate from both upper and lower surfaces, and a cutting edge on a single sheet unloading side of the pair of rolls, which is directed in a direction opposite to the transport direction, is a cutting blade. A cutting blade provided at a position in contact with a peripheral surface of each of the rolls on the carry-out side from a single plate clamping position of the pair of rolls by rotating the cutting blade about the base; The cutting blade reciprocating rotation mechanism for reciprocatingly rotating the pair of rolls within the opposing interval of the pair of rolls, and the reciprocating rotation mechanism of the cutting blade are coupled to the pair of rolls each time a single plate cutting signal is responded. Rotate one way within the interval between the rolls so that the cutting edge By to a controller from a peripheral surface of one of the rolls has a circumferential surface of the other roll opposite to the abutment consists of veneer cutting device, has been cut veneer rotates the cutting blade. However, such a single-plate cutting device has the following problems. That is, the continuous veneer conveyed by the carrying mechanism such as a conveyor, the center, right side, left side in the direction orthogonal to the conveying direction, the material, cracking state, avale state is different respectively, during the conveyance or the pair The veneer may meander when loaded between the rolls, and in particular, if the veneer veneer is carried between the pair of rolls during transportation by the loading mechanism, the veneer of the veneer may be further promoted. However, in any case, there is a problem that an accurate cutting perpendicular to the transport direction cannot be performed. In particular, in the latter case, it is extremely difficult to correct the meandering of the veneer with an ordinary meandering correction device.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a veneer cutting apparatus and a veneer cutting method which eliminates meandering of a veneer to be carried in, in order to solve the above problems. .

[0004]

In order to achieve the above object, according to the first aspect of the present invention, one roll constituting a pair of rolls is moved with respect to the other roll. A reciprocating mechanism for reciprocating the veneer in a direction away from the veneer is provided so that the rolls of the veneer are separated at the end of the veneer cutting, and the sandwiched state of the veneer is released at the end of the veneer cutting. Here, the reciprocating mechanism is configured to reciprocate both the upper and lower rolls, even if only one of the rolls is reciprocated. The mechanism may also include a first moving mechanism that always moves in a direction away from the first moving mechanism and a second moving mechanism that moves in a direction in which the moving mechanism approaches and overcomes the moving force of the first moving mechanism. It may be composed of two mechanisms.
In addition, the controller controls the reciprocating mechanism, and more specifically, controls the reciprocating mechanism to rotate the reciprocating mechanism after cutting the veneer by the cutting blade.
In this case, the first moving mechanism operates to move in the direction in which the first moving mechanism always moves away from each other and moves in the direction approaching each other at the time of the next cutting. Therefore, it is sufficient to control only the operation of the second moving mechanism. That is, the operation of the second moving mechanism is released after the cutting is completed, and the two rolls are operated so as to move in a direction approaching each other at the time of cutting. Of course, the second moving mechanism may be positively operated so as to move the two rolls away from each other after the cutting is completed. In addition, the cutting blade is, for example, in the case of fixed-size cutting, a detector provided on an upper and lower two-stage carrying-out mechanism, in the case of dimensional cutting, related to the detection operation of a detector provided on the carrying-in mechanism The reciprocating mechanism is controlled based on these detection signals or the veneer cutting signal. The invention according to claim 4 is
This invention relates to a veneer cutting method. After the veneer is cut, both rolls are released to release the sandwiched state of the veneer, and at the time of cutting, the rolls are returned to their original positions to maintain the sandwiched state. Thus, cutting is performed while changing the interval between the two rolls. The direction related to the change of the interval between the two rolls may be a direction orthogonal to the conveying direction of the veneer as in the invention of claim 6 or the veneer as in the invention of claim 7 May be the same direction as the transport direction.

[0005] In the invention described in each of the above claims, the veneer is pinched by a pair of rolls at the time of cutting, and the pinch is released after the cutting is completed. Therefore, the veneer does not meander, and the meandering of the veneer carried in the meandering is not further promoted, so that it is hardly difficult to correct the meandering by any meandering correcting device.

FIGS. 14 to 17 are flowcharts showing different embodiments of the roll reciprocating mechanism.

First, referring to FIG. 1, an entire veneer will be described. However, the embodiment shown here shows a case in which the present invention is applied to a fixed-size cutting of a continuous veneer. A pair of rolls 1 and 3 rotatably held by bearings 5 and 7 are vertically arranged, and a spur gear (not shown) attached to the shaft of each roll 1 and 3 is engaged. , Both electric motors (not shown) connected to the shaft of the roll 3
The nozzles 1 and 3 are configured to be rotatable in the arrow direction. Roll 1,
3, a front conveyor 9 is provided as a carry-in mechanism on the veneer carry-in side, and carries the veneer P between the pair of rolls 1 and 3. The pair of rolls 1 and 3 hold the single plate P carried in between the two rolls and transport the single plate P to a subsequent process.

On the single sheet unloading side of the rolls 1 and 3, a cutting blade 11 held by a blade holder 13 is provided with its cutting edge directed in a direction opposite to the conveying direction. The cutting blade 11 is rotatable within the interval between the pair of rolls so that the cutting blade 11 can abut on each roll peripheral surface on the unloading side from the single plate clamping position. And Reference numeral 16 designates the blade holder 13 as an arm 1
The cylinder is reciprocally rotated through the lever 4 and is operated by a controller described later. In this embodiment, the cutting blade 11
Is held by the blade holder 13, but the cutting blade 1
1 and the blade holder 13 may be formed integrally.

Reference numeral 17 denotes a veneer guide whose tip is provided slightly away from the peripheral surface of the roll 3. A conveyer 21 for carrying out the veneer P is provided on the carry-out side thereof. Thereafter, above the conveyor 21, the blade holder 13
A rear conveyor 19 is also provided on the carry-out side of the conveyor, and the upper and lower rear conveyors are used. Reference numerals 23 and 25 denote fixed-size detectors for detecting the leading ends of the single plates P sent on the rear conveyor, and the detection signals are sent to a controller described later.

FIG. 2 shows one side of a reciprocating mechanism for reciprocating the upper roll 1 in a vertical direction. A cylinder rod is mounted on a support 35 projecting inside the outer frame. A cylinder 37 as a first moving mechanism having a cylinder rod protruded upward, and a second cylinder 37 having a cylinder rod protruded downward.
The mounting and fixing is performed with the cylinder 33 as a moving mechanism in the opposite direction. That is, the cylinder tube of the cylinder 33 is mounted on the support base 35 so that the rod faces downward.
The cylinder tube of the cylinder 37 is mounted on the cylinder tube so that the rod faces upward. The bearing 5 and one end of the auxiliary arm 31 are attached to the tip of the rod of the cylinder 33. On the other hand, cylinder 3
The tip of the rod 7 is brought into contact with a stopper 39 attached to the other end of the auxiliary arm 31.

The cylinder 37 is constructed such that the rod always projects upward and the auxiliary arm 31 is pushed up through a stopper 39.
It is operated by a controller described later based on the detection signals of 3, 25. The pressing force of the cylinder 37 is set smaller than the pressing force of the cylinder 33.

Next, the operation of the embodiment configured as described above will be described. First, with reference to FIGS. 3 to 5, a description will be given of pinching of the veneer P by the rolls 1 and 3 and release of the pinching. FIG. 3 shows a state in which the clamping of the veneer P is released, and the veneer immediately after cutting (more precisely, a continuous veneer whose front end is cut) P
Is transported by the front conveyor 9 and the rear conveyor 21 (13). In this state, a signal from the controller issued based on the detection signal of the detector causes the cylinder 3
The supply of the compressed air to the B chamber 3 is stopped, and the cylinder 33 is stopped.
There is no pushing force. Further, since the compressed air is constantly supplied to the C chamber of the cylinder 37, the rod of the cylinder 37 pushes up the auxiliary arm 31 via the stopper 39 by the pressing force of the cylinder 37 to raise the bearing 5 and the roll 1. . At this time, the gap S between the upper surface of the single plate P and the peripheral surface of the roll 1 is preferably about 1 millimeter, and the adjustment is performed by the stopper 39. At this time, if the supply to the chamber A is performed simultaneously with the stop of the supply of the cylinder 33 to the chamber B, the cylinder 3
3 can be quickly eliminated, and the operation by the cylinder 37 can be performed smoothly.

FIG. 4 shows a state in which the veneer P is sandwiched. The veneer P is conveyed by being sandwiched between the front and rear conveyors and both the rolls 1 and 3. In this state, a signal from the controller issued based on the detection signal of the detector causes the cylinder 3
Compressed air is sent to the B room 3 and the air in the A room is discharged. On the other hand, the pushing force of the cylinder 37 is still maintained, but the pushing force of the cylinder 33 downward (in a direction in which the two rolls approach) is higher than the cylinder 37 (the two rolls).
Is greater than the pushing force in the direction in which the bearings 5 and rolls 1 are released.
Descends. At the same time, the stopper 39 pushes back the rod of the cylinder 37 via the auxiliary arm 31, and the rod contracts.

FIG. 5 shows a state in which the roll 1 is largely raised due to cleaning or trouble of the roll 1. In this state, the maximum compressed air is supplied to the chamber A of the cylinder 33. , B air is exhausted. As a result, the rod of the cylinder 33 contracts to the maximum, causing the roll 1 to rise significantly.

Next, the overall operation will be described. In the operation state shown in FIG. 1, the front conveyor 9, the rolls 1, 3, and the rear conveyors 19, 21 are constantly rotating.

In FIG. 1, a continuous veneer P is transported on a front conveyor 9, a pair of rolls 1, 3 and a lower rear conveyor 21. The tip of the veneer P is detected by a detector 25. Then, a detection signal is issued, and the signal is sent to the controller. Then, a cutting signal is issued from the controller, the valve V2 is operated, the cylinder 16 is operated, and the cutting blade 11 is brought into contact with the peripheral surface of the roll 1 from the peripheral surface of the roll 3 in the direction of arrow G. One way rotation. At the same time, another signal is issued from the controller, the valve V1 is operated, compressed air is supplied to the chamber B of the cylinder 33, the air in the chamber A is discharged, the roll 1 is lowered, and the veneer P is removed. Rolls 1 and 3 pinch. (See Fig. 6)

The continuous veneer P is cut by the rotation of the cutting blade 11, and the veneer P, the rear end of which is cut, is moved to the next step by the lower rear conveyor 21, and the subsequent veneer P is moved to the upper stage. It is transported to the rear conveyor 19. (See Fig. 7)

After the time required to cut the single plate P by the delay circuit has elapsed, a signal is issued from the controller,
By operating the valve V1, the supply of the compressed air to the B chamber of the cylinder 33 is stopped. As a result, the downward pressing force of the cylinder 33 is eliminated, and the upward pressing force of the cylinder 37 is exerted, so that the roll 1 slightly rises above the upper surface of the veneer P (see FIG. 8).

Further, when the veneer P is conveyed on the rear conveyor 19 and the tip of the veneer P is detected by the detector 23 (see FIG. 9), a detection signal is issued and the signal is sent to the controller. Sent. Then, a cutting signal is issued from the controller, the valve V2 is operated, the cylinder 16 is operated, and the cutting blade 1 is operated.
1 is rotated one way in the direction of arrow H so that the peripheral surface of the roll 3 comes into contact with the peripheral surface of the roll 1. At the same time, another signal is issued from the controller, the valve V1 is operated, compressed air is supplied to the chamber B of the cylinder 33, the air in the chamber A is discharged, the roll 1 is lowered, and the veneer P is removed. Rolls 1 and 3 pinch. (See Fig. 10)

The continuous veneer P is cut by the rotation of the cutting blade 11, and the veneer P whose rear end is cut is moved to the next step by the upper rear conveyor 19, and the subsequent veneer P is moved to the lower stage. It is transported to the rear conveyor 21. (See Fig. 11)

After the time required to cut the single plate P by the delay circuit has elapsed, a signal is issued from the controller,
By operating the valve V1, the supply of the compressed air to the B chamber of the cylinder 33 is stopped. As a result, the downward pressing force of the cylinder 33 is eliminated, and the upward pressing force of the cylinder 37 causes the roll 1 to slightly rise above the upper surface of the single plate P (see FIG. 12). By repeating the above operation, the continuous veneer is sequentially cut to a fixed size. The control will be described in detail again with reference to the flowchart of FIG. In FIG. 13, the front conveyor 9 is driven, and the driving of the rolls 1, 3 and the driving of the conveyors 19, 21 are started.
When the veneer is detected by the detector 23, the cutting blade 11 is rotated upward,
When the veneer is detected by the detector 25, the cutting blade 11 is rotated downward, and the roll 1 is lowered by either veneer detection of the detectors 23 and 25 to cut the veneer. When the time set by the descent timer elapses, roll 1
And the holding of the veneer is released. Unless the operation is finished, return to the veneer detection step by the detector,
The cutting is sequentially performed by repeating the above steps. In this embodiment, the diameters of the rolls 1 and 3 are 150 mm, the distance between the peripheral surfaces of the rolls at the time of holding and releasing the veneer is the thickness of the veneer + 1 mm, the transport speed is 120 mm / m, and the timer is used. Is 0.05 seconds.

In the above construction, the veneer P is pinched by the pair of rolls 1 and 3 at the time of cutting, and the pinching is released after the cutting is completed. Therefore, the veneer does not meander, and the meander of the veneered veneer does not increase. The meandering correction by the meandering correction device can also be easily performed.
Further, the normal release of the clamp, that is, a short rise of the stroke, is performed by the cylinder 37, and the release of the non-normal clamp, that is, the long rise of the stroke due to the cleaning of the roll or trouble is performed by the cylinder 33. Therefore, when cutting the veneer P, so-called ordinary pinching, the time required for lowering the roll 1 can be short, and the responsiveness is high. On the other hand, even if two or three veneers P are loaded in a stack, the stroke of the cylinder 33 is long.
Is raised, that is, the thickness of the laminated veneer is
3, and there is almost no trouble such as clogging.

In the above embodiment, when releasing the sandwiched state of the single plate P, the supply of the compressed air to the chamber B of the cylinder 33 is stopped, but the compressed air is supplied to both the chambers A and B. They may be sent at the same time. In the above embodiment, when the veneer A is sandwiched, the compressed air in the chamber C of the cylinder 37 remains unchanged, but the compressed air in the chamber C may be discharged. However, in this case, when releasing the sandwiched state of the veneer P, it is necessary to supply compressed air to the chamber C again.

Further, the rear conveyor 1 as in the above embodiment is used.
Instead of the fixed-size detectors 23 and 25 on the components 9 and 21, a fixed-size detector may be provided on the front conveyor 9. The cutting blade may be provided on the front conveyor 9 to operate the cutting blade based on the detection signals of those detectors. Moreover, the cutting blade may be operated at appropriate time intervals by the controller irrespective of the presence or absence of the veneer.

The pushing force of the cylinder 33 is set to be larger than the force. Then, when releasing the holding of the veneer P by the rolls 1 and 3, the compressed air is supplied to the chamber B of the cylinder 33 and the compressed air of the chamber A is discharged.
The compressed air is supplied to the chamber D of the cylinder 51, and the compressed air in the chamber C is discharged. Next, when sandwiching the veneer P between the rolls 1 and 3, compressed air is supplied to the chamber B of the cylinder 33 and compressed air is discharged to the chamber C of the cylinder 51 while the compressed air of the chamber A is discharged. The air is supplied and the compressed air in the chamber D is discharged.
When the roll 1 is to be raised significantly for cleaning or trouble, the compressed air is supplied to the chamber A of the cylinder 33 and the compressed air in the chamber B is discharged. 53 is a roll 1,
It is a stopper for adjusting the gap between the three.

Then, when releasing the holding of the veneer P by the rolls 1 and 3, the supply of the compressed air to the chamber B of the cylinder 33 is stopped,
The roll 1 is raised by the weight of the weight 59. Next, when sandwiching the veneer P between the rolls 1 and 3, the compressed air is supplied to the chamber B of the cylinder 33 and the air in the chamber A is discharged. When the roll 1 is to be raised significantly for cleaning or trouble, the compressed air is supplied to the chamber A of the cylinder 33 and the compressed air in the chamber B is discharged.

FIG. 16 shows still another embodiment, in which a cylinder 33 as a second moving mechanism is provided on the roll 1 side, and a compression spring 65 as a first moving mechanism is provided in the cylinder 33. Cylinder 33 from the pressing force of spring 65
