Description

TECHNICAL FIELD The present invention relates to a device for efficiently winding a veneer veneer cut by a veneer lace onto a take-up reel.

“Prior Art” Conventionally, as shown in FIG. 7, a veneer veneer 1 cut with veneer lace is conveyed on a carry-in conveyor 2 and is separated from a pulley 3 at its end by an appropriate distance. Side drive roll 4 and take-up reel 5 that rotates in pressure contact
The winding balls 6 that have been wound up and have been wound up move up in the reel support 8 through the elevating device 7 and are transferred to the transfer rail 10 of the winding ball stock area 9. Next, the next take-up reel 5 is lowered from the return rail 12 of the reel stock area 11 onto the side drive roll 4 to start new take-up.

Usually, the area of the veneer veneer 1 obtained by cutting the raw wood 13 is a portion excluding the outermost scrap portion and the innermost chuck gripping portion, as shown in FIG.
Although it depends on the grade of the log 13 and the type of the tree, in one log 13, the veneer veneer 1 for the relatively thinly cut plywood, which is the front and back plates of plywood, and the relatively thick veneer, which is the middle plate The veneer veneer 1 for the middle plate to be cut is roughly classified.

When these areas are separated from the outermost side, based on FIG. 8, 14 is a scrap portion, 15 is a fragile portion of the sapwood layer, 16 is a veneer veneer part for middle plate, 17 is a veneer veneer part for original plate, 18 Is a veneer veneer part for an intermediate plate, 19 is a fragile part of the core material layer, and 20 is a chuck gripping part.

Therefore, when starting to cut one log 13, the scrap portion 14,
When the veneer veneer veneer part 16 for the intermediate plate is passed through the fragile part 15 of the sapwood layer, the veneer veneer veneer 1 for the intermediate plate to be cut is wound on the take-up reel 5, but the veneer for the original plate is used. Veneer part
At the time of shifting to 17, the winding is temporarily interrupted, the winding balls 6 of the veneer veneer 1 for the intermediate plate are transferred to the transfer rail 10 of the winding ball stock area 9, and the reel stock area 11
The new take-up reel 5 is lowered from the return rail 12 to take up the veneer veneer 1 for the original plate. Further, when the inner layer veneer single plate portion 18 for the inner layer is reached, it becomes necessary to replace the take-up reel 5 again.

[Problems to be Solved by the Invention] If the veneer veneer 1 has a different thickness, the drying time in the veneer dryer in the subsequent stage is different, so that both cannot be wound on the same take-up reel 5. No, one log
In 13, even though the winding ball 6 does not reach an arbitrary diameter, 3
The take-up reel 5 for the book is required, and the take-up reel 5 must be moved down from the take-up ball stock area 11 each time.

"Means for solving the problem" In view of the above, the present invention has a carrying conveyor and a side drive roll arranged side by side on a pedestal whose end can be swung with the starting end of the veneer veneer carrying side as a fulcrum, A reel receiver is attached to a reel post that is erected at an extension position on both sides of this side drive roll, and a winding roll that rotates in pressure contact with the side drive roll is supported on this reel receiver.

While suspending 83, one chain wheel 81 is driven to drive a prime mover 84.

Next, the operation will be described.

First, when cutting a piece of raw wood 13, as shown in the acquisition area of the veneer veneer 1 in FIG. 8, the scrap portion 14 of the raw wood 13 and the fragile portion 15 of the sapwood layer are not used as plywood. Is discharged to the outside of the machine.

For this reason, the rod 27 of the pressure-reducing fluid cylinder 26 is extended to push down the end of the pedestal 21 with the vicinity of the starting end pulley shaft 22 as a fulcrum, and to bring the conveyor 2 into a substantially horizontal state. Move diagonally down 54.

At the same time, the rod 45 of the pressurized fluid cylinder 44 is contracted,
The pressure pulley 42 is rotated to make the take-up guide belt 47 substantially horizontal, and a fluid cylinder for raising and lowering the carry-out conveyor.
By extending the rod 31 of 30 and pushing down the machine frame 32, the carry-out conveyor 36 is lowered to the same height as the carry-in conveyor 2.

Further, the sliding frame 53 is moved obliquely upward along the sliding guide 54 by the operation of the sliding frame lifting / lowering fluid cylinder 51, and the pressing roll 59 is retracted above the transport surface.

Under this condition, the narrow veneer veneer 1 of the scrap portion 14 cut from the raw wood 13 and the fragile portion 15 of the sap layer is transferred to the carry-in conveyor 2
It is conveyed above, passes below the pressing roll 59 and the take-up reel 5, and is taken out of the machine by the take-up guide belt 47 and the carry-out conveyor 36.

Then, the veneer veneer veneer part 16 for the middle layer of the outer layer from the log 13,
When cutting relatively thick, stop each drive once and
21, winding guide belt 47, carry-out conveyor 36, sliding frame 53
To the winding state.

That is, with the pedestal 21 as the fulcrum of the starting end pulley shaft 22, the pressing fluid cylinder 23 oscillates the end portion thereof upward, so that the outer peripheral upper surface of the side drive roll 4 is pressed against the outer peripheral lower surface of the take-up reel 5 and slides. The rod 52 of the frame elevating / lowering fluid cylinder 51 is contracted, and the pressing roll 59 is taken up by the take-up reel 5
Bias to the side of. Further, the pressurizing fluid cylinder 44 urges the pressurizing pulley 42 toward the outer peripheral side surface of the take-up reel 5,
The winding guide belt 47 is stretched along the lower side of the outer peripheral side surface of the winding reel 5. Further, the carry-out conveyor 36 is lifted by the operation of the carry-out conveyor lifting / lowering fluid cylinder 30, and the pressure roll 37 is placed opposite to the side surface of the take-up reel 5 at an appropriate interval. At this time, the pressurizing body 72 is urged toward the side surface of the take-up reel 5 by the pressurizing-body pressing fluid cylinder 68, and the take-up guide member 74 is stretched along the outer peripheral upper surface of the take-up reel 5.

Then, the cutting speed and the conveying speed are synchronized, and the veneer veneer 1 for the intermediate plate is supplied to the take-up reel 5 by the carry-in conveyor 2, and the tip portion thereof is guided along the take-up guide belt 47 and the take-up guide member 74. And wind it around the outer peripheral surface of the take-up reel 5.
During the winding operation, the reduction force accompanying the increase of the diameter of the winding ball 6 overcomes the pressing force of the pressing fluid cylinder 23, and the amount of the increase of the diameter of the winding ball 6 increases the mount.
Swing 21 downwards in sequence.

With the increase in the diameter of the winding ball 6, the pressure pulley 42, which initially urged the vicinity of the center of the side surface of the take-up reel 5, is pushed by the winding ball 6 and swings forward, and further, By swinging downward, the winding range of the winding guide belt 47 around the winding ball 6 is also sequentially moved downward. On the other hand, the pressure roll 37, which is provided opposite to the vicinity of the center of the side surface of the take-up reel 5 at an appropriate distance, is pushed by the winding ball 6 when the winding ball 6 has an appropriate diameter, for example, 190 mm to 200 mm. It is swung forward in sequence.

When the gantry 21 swings downward and the pressure roll 37 swings forward, the pressure roll 37 and the veneer veneer introducing member 39 expand. However, the lower side of the outer peripheral side surface of the winding ball 6 has a lower winding drum. The veneer veneer introducing member 39, which is sequentially unwound from 38, surrounds it. In this case, the amount of change in the biasing position of the pressure roll 37 with respect to the winding ball 6 is made small, and the enclosing range of the winding ball 6 of the veneer veneer introducing member 39 is gradually expanded downward.
Since the positions of the guide body 40 and the lower winding drum 38 are set, the veneer veneer 1 is linked to the winding guide belt 47 and the veneer veneer introducing member 39 so that the veneer veneer 1 has its veneer veneer 1 unloading side. It will be installed near the center of the side.

Further, the pressing roll 59, which initially biased the vicinity of the center of the side surface of the take-up reel 5 on the veneer veneer 1 loading side, is moved downward along the sliding guide 54, and the veneer veneer 1 is unloaded. The pressurizing body 27, which has been biased near the center of the side surface, is pushed by the winding ball 6 and is swung forward.

As the pressing roll 59 is moved obliquely downward and the pressing body 72 is swung forward, the winding guide member 74 is sequentially rewound from the upper winding drum 73 along the outer circumference of the winding ball 6. In this case, the change amount of the biasing position with respect to the pressurizing body 72 is made small,
Further, the pressing roll 59 is set so as to move obliquely downward with the swing of the pedestal 21 while urging the winding ball 6, so that the winding guide member 74 carries the winding ball 6 out of the veneer single plate 1. From the vicinity of the center of the side surface to the vicinity of the inlet of the veneer veneer 1 through the upper surface of the outer periphery, the winding is always performed.

Therefore, the veneer veneer 1 on which the winding balls 6 wound on the take-up reel 5 have been conveyed on the carry-in conveyor 2 from the minimum diameter to the arbitrary diameter, the winding guide belt 47 and the veneer veneer introducing member 39. Due to the linking action with and the winding guide member 74, the winding is carried out sequentially following the outer periphery thereof.

Then, when the acquisition portion of the veneer veneer 1 shifts from the veneer veneer veneer portion 16 for the middle plate to the veneer veneer veneer portion for the original plate as shown in FIG. Stop the work. Next, the rod 69 of the fluid cylinder 68 for pressing the pressurizing body is contracted, the linking arm 71 is rotated clockwise in FIG. 4, and the rod 64 of the fluid cylinder 63 for rocking frame rotation is contracted to make the sprocket shaft. With 60 as the fulcrum,
By rotating the swinging frame 62 in the clockwise direction, the winding guide member 74 is released from the upper surface of the winding ball 6.

At this time, if the winding ball 6 of the veneer veneer 1 for the intermediate plate has an arbitrary diameter, the inside of the reel support 8 is lifted by a lifting hook (not shown) via the lifting device 7, and the winding ball stock area 9 of the winding ball stock area 9 is lifted. Transfer to the lower transfer rail 10.

On the contrary, if the winding ball 6 of the veneer veneer 1 for the intermediate plate does not reach the arbitrary diameter, the end of the pedestal 21 is pushed down, and the pressure pulley 42 and the machine frame 32 are lowered to wind up. The guide belt 47 and the carry-out conveyor 36 are opened to a position that does not interfere with the carry-out work.

Next, the chain 83 is rotated by driving the prime mover 84,
By the standby hook 82 retracted below the reel receiver 75,
By locking both shafts of the take-up reel 5 and rolling them on the standby rail 80, the winding reel 5 is once transported to the standby position and stopped at that position.

After that, on the reel receiver 75, the return hook from the return rack 77
The new take-up reel 5 is supported by 78, the pedestal 21,
The winding guide belt 47, the carry-out conveyor 36, and the sliding frame 53 are returned to the winding state described above, and the veneer veneer portion for the original plate is formed.
The veneer veneer 1 for original plate, which is relatively thinly cut from 17, is wound on a new winding reel 5.

During the winding, as shown in FIG. 8, when the veneer veneer part 17 for the original plate is transferred to the veneer veneer veneer part 18 for the inner plate of the inner layer,
While suspending the cutting, the winding work is also stopped,
As described above, the winding ball 6 with the winding guide member 74 opened from the upper surface is transferred to the upper transfer rail 10 of the winding ball stock area 9. During this time, the pedestal 21, the winding guide belt
47, open the carry-out conveyor 36 to a position that does not interfere with the carry-in work.

Then, the chain 83 is reversely rotated by the prime mover 84, the take-up reel 5 at the standby position is engaged with the standby hook 82, and the standby rail 80 is rolled to the reel receiver 75. Thereafter, the side drive roll 4, the winding guide belt 47, the winding guide member 74, etc. are wound around the outer peripheral surface of the winding ball 6 in the middle of winding, and the inner layer veneer veneer single plate portion 18 for the inner layer is relatively moved. The thickly cut veneer veneer 1 for the middle plate is wound into a winding ball 6
To rewind.

Thereafter, the above work is repeated until the winding ball 6 reaches an arbitrary diameter, and when the winding ball 6 reaches the arbitrary diameter, it is transferred to the lower transfer rail 10 of the winding ball stock area 9 through the elevating device 7.

Thus, the take-up reel 5 and the winding ball 6 are formed by the action of the take-up guide belt 47 and the veneer veneer introducing member 39 in association with each other.
Since the side surface of the veneer veneer 1 on the unloading side is wound and is wound from the upper surface of the outer periphery thereof to the vicinity of the inlet of the veneer veneer 1 by the take-up guide member 74, the veneer veneer 1 to be conveyed is wound on the take-up reel. It is automatically introduced into No. 5 and wound up to an arbitrary diameter.

[Effect] As described above, according to the present invention, the carry-in conveyor and the side drive rolls are provided side by side on the pedestal with the starting end of the veneer veneer carry-in side as a fulcrum, and the side drive rolls are erected at both side extended positions. A reel support is mounted on a reel support, and a take-up reel that rotates in pressure contact with the side drive roll is supported on the reel support. Furthermore, a standby position separated from the vicinity of the reel support to the veneer veneer carry-out side by an arbitrary distance. In between, a pair of standby rails on which both end trochanters of the take-up reel roll are disposed, and a standby hook movable along the standby rails is engaged with both shaft portions of the take-up reel. Since the veneer plate of the same thickness has a desired diameter, the veneer plate can be wound in the standby position once while waiting. Therefore, the winding ball ratio of one take-up reel is increased, and accordingly, the time required for replacing the take-up reel can be shortened.
Workability can be improved.

Furthermore, when rewinding a veneer veneer to a veneer dryer, conventionally, the rewinding amount of the reed balls that does not reach an arbitrary diameter is small, and the empty take-up reel after rewinding and the rewinding ball to be rewound next Since the number of replacements of the veneer is increased, the filling rate of the veneer veneer in the veneer dryer was decreased during this period.However, according to the present invention, since each winding ball has an arbitrary diameter, it is possible to avoid the decrease of the filling rate. become.
