In this connection, when shifting from the veneer for thick plate use to the medium plate veneer, cutting is suspended, opening a member 74, and the winding spool 6 is transferred onto the upper stage transfer rail in advance.

Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention relates to an apparatus for efficiently winding up 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 a veneer lace is conveyed on an incoming conveyor 2, and is placed at an appropriate distance from a pulley 3 at the end of the conveyor. A take-up reel 5 rotates in pressure contact with the side drive roll 4
The rolled ball 6 which has been wound up by the winding device 7 rises within the reel support 8 via the lifting device 7, and is transferred to the transfer rail 10 of the rolled ball stock area 9. Next, the next take-up reel 5 is lowered from the return rail 12 of the reel stock area 11 to above the side drive roll 4, and a new take-up is started.

Usually, the area of the veneer veneer 1 obtained by cutting the raw wood 13 is the area excluding the outermost layer part and the innermost chuck gripping part, as shown in FIG.
Although it varies depending on the grade and species of the log 13, in a single log 13, there is a veneer veneer 1 for the original plate that is cut relatively thinly to become the front and back plates of the plywood, and a relatively thin veneer veneer 1 for the original plate to be cut to be the front and back plates of the plywood. It is roughly divided into veneer veneers 1 for medium plates that are cut thickly.

When these areas are classified from the outermost side, based on FIG. 8, 14 is a layer part, 15 is a weak part of the sapwood layer, 16 is a veneer veneer part for the middle board, 17 is a veneer veneer part for the original board, and 18
19 is the weak part of the core material layer, 2 is the veneer veneer part for the middle plate,
0 is the chuck gripping part.

Therefore, when starting to cut one log 13, layer portion 1
4. After passing through the weak part 15 of the sapwood layer and reaching the middle board veneer part 16, the middle board veneer 1 to be cut is as follows:
It is wound onto the winding reel 5, but when it moves to the original veneer veneer portion 17, the winding is temporarily interrupted and the veneer veneer 10 for the intermediate plate 10 is rolled into the rolled ball stock area 9. A new winding 1- is transferred from the return rail 12 of the reel stock area 11 to the transfer rail 10 of
The handle 5 is lowered and the veneer veneer 1 for the original plate is wound up.

Furthermore, when the inner layer reaches the intermediate veneer veneer portion 18, it becomes necessary to replace the winding reel 5 again.

"Problem to be Solved by the Invention" However, if the thickness of the veneer veneer 1 is different, the drying time in the subsequent veneer dryer will be different, so it is not possible to wind up both on the same winding reel 5. First, even though the rolled balls 6 do not reach an arbitrary diameter in one log 13,
Three winding series 5 are required, and the winding ball 6 is required each time.
The winding reel 5 must be lowered from the bobbin stock area 11.

``Means for Solving the Problems'' In view of the above, the present invention includes a carry-in conveyor and a side drive roll arranged side by side on a frame whose terminal end is swingable with the start end of the veneer veneer carry-in side serving as a fulcrum.

The chain wheel 83 is suspended, and one of the chain wheels 81 is driven to drive the prime mover 84.

Next, the effect will be explained.

First, when cutting one log 13, as shown in the acquisition area of the veneer veneer 1 in FIG.
Since the weak parts 15 of the sapwood layer are not used as plywood, they are discharged to the outside of the machine.

For this reason, the rod 27 of the compressing fluid cylinder 26 is extended, and the pedestal 21 is set near the starting end pulley shaft 22 as a fulcrum.
The sliding frame 53 is moved diagonally downward along the sliding guide 54 while pushing down the terminal end and keeping the carry-in conveyor 2 in a substantially horizontal state.

At the same time, the rod 45 of the pressurized fluid cylinder 44 is contracted, the pressurizing pulley 42 is rotated, and the winding guide belt 47 is rotated.
By bringing the conveyor to a nearly horizontal state, extending the rod 31 of the fluid cylinder 30 for elevating the conveyor, and pushing down the machine frame 32, the conveyor 36 is lowered to the same height as the conveyor 2. Further, the sliding frame 53 is moved diagonally upward along the sliding guide body 54 by the operation of the sliding frame outer descending fluid cylinder 51, and the press roll 59 is retracted above the conveying surface.

Under this condition, the narrow-width veneer 1 of the weak portion 15 of the sliding sapwood layer cut from the log 13 is conveyed on the carry-in conveyor 2 and passes below the suppression roll 59 and the take-up reel 5. , winding guide belt 47, and unloading conveyor 36
is carried out of the aircraft.

Next, from the raw wood 13, a veneer veneer portion 16 for the middle board of the outer layer is
When cutting relatively thickly, stop each drive once,
Frame 21, winding 9 guide belt 47, unloading conveyor 36,
The sliding frame 53 is returned to the winding state.

That is, the pedestal 21 is pivoted upward by the pressing fluid cylinder 21 with the starting end pulley shaft 22 as a fulcrum,
The upper surface of the outer periphery of the side drive roll 4 is
At the same time, the rod 52 of the slide frame elevating fluid cylinder 51 is contracted to urge the pressure roll 59 toward the side surface of the take-up reel 5.

Further, the pressure pulley 42 is urged by the pressurized fluid cylinder 44 toward the outer circumferential side of the take-up reel 5, and the take-up guide belt 47 is stretched along the lower side of the outer circumferential side of the IJ-rule 5. Further, the discharge conveyor 36 is raised by the operation of the fluid cylinder 30 for raising and lowering the discharge conveyor, and the pressure roll 37 is disposed opposite to the side surface of the take-up reel 5 at an appropriate distance. 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 circumferential upper surface of the take-up reel 5.

Next, by synchronizing the cutting speed and the conveyance speed, the veneer veneer 1 for the intermediate plate is supplied to the winding reel 5 by the carrying-in conveyor 2, and the leading end portion is passed through the winding guide belt 47 and the winding guide member 74. Wrap it around the outer peripheral surface of the take-up reel 5 along. During winding, as the diameter of the winding ball 6 increases, the reduction blade overcomes the pressing force of the pressurized fluid cylinder 23 and sequentially swings the pedestal 21 downward by the increase in the diameter of the winding ball 6.

With this increase in the diameter of the winding ball 6, the pressure pulley 42, which was initially urging the vicinity of the center of the side surface of the winding reel 5, is pushed by the winding ball 6 and swings forward. Due to the downward swing, the winding guide belt 47 also moves the winding ball 6 around the range.
It will move sequentially downward. On the other hand, the pressure roll 37, which was disposed opposite to the vicinity of the center of the side surface of the winding reel 5 at an appropriate interval, has an appropriate diameter as indicated by the winding ball 6, for example, 1901 to 2.
When it reaches 000, it is pushed by the winding ball 6 and then sequentially swung forward.

When the pedestal 21 swings downward and the pressure roll 37 swings forward, the pressure roll 37 and the veneer veneer introduction member 39 are expanded, but the lower part of the outer peripheral surface of the winding bobbin 6 is It is surrounded by a veneer veneer introduction member 39 which is sequentially unwound from 38. In this case, the pressure roll 37
The guide body 40 and the lower winding citrus 38 are arranged so as to minimize the amount of change in the biasing position of the winding ball 6 with respect to the winding ball 6, and to sequentially expand the surrounding range of the winding ball 6 of the veneer veneer introduction member 39 downward. Since the position is set, the veneer veneer 1 is introduced to the vicinity of the center of the side surface of the veneer veneer 1 on the unloading side of the winding ball 6 due to the cooperation between the winding guide belt 47 and the veneer veneer introducing member 39. That will happen.

Furthermore, the pressure roll 59 that was initially urging the vicinity of the center of the veneer veneer 1 carry-in side side of the winding I, 1-ru 5,
The pressurizing body 72 was moved downward along the sliding guide body 54 and was urging the vicinity of the center of the side surface on the unloading side of the veneer veneer 1.
is pushed by the winding ball 6 and is swung forward.

As the suppression roll 59 is moved obliquely downward and the pressurizing body 72 is swung forward, the winding guide member 74 moves the winding ball 6
It is sequentially unwound from the upper winding citrus 73 along the outer circumference. In this case, the amount of change in the biasing position with respect to the pressure body 72 is minimized, and the pressure roll 59 is set to move diagonally downward as the pedestal 21 swings while biasing the winding ball 6. Therefore, the winding guide member 74 always wraps the winding bobbin 6 from the vicinity of the center of the side surface of the veneer veneer 1 on the unloading side, through the upper surface of the outer periphery, to the vicinity of the inlet of the veneer veneer 1.

Therefore, the veneer veneer 1 that has been transported on the carry-in conveyor 2 from the minimum diameter to the arbitrary diameter of the spool 6 wound on the winding reel 5 is connected to the winding guide belt 47 and the veneer veneer introduction member. 39 and the winding guide member 74
As a result, the material is sequentially wound along its outer circumference.

When the obtained portion of the veneer veneer 1 shifts from the intermediate veneer veneer portion 16 to the original veneer veneer portion 16, as shown in FIG. The work will also be stopped. Next, the rod 69 of the pressure body pressing fluid cylinder 68 is contracted, the linking arm 71 is rotated clockwise in FIG. axis 60
By rotating the swing frame 62 clockwise about the fulcrum, the winding guide member 74 is opened from the top surface of the winding ball 6.

At this time, if the rolled balls 6 of the veneer veneer 1 for the middle plate have an arbitrary diameter, they are hoisted up and down inside the reel support 8 using a lifting hook (not shown) via the lifting device 7, and moved to the rolled ball stock area. 9 onto the lower transfer rail 10.

Conversely, if the winding ball 6 of the medium veneer veneer 1 does not reach the desired diameter, the terminal end of the pedestal 21 is pushed down, the pressure pulley 42 and the machine frame 32 are lowered, and the winding is performed. The guide belt 47 and the carry-out conveyor 36 are opened to a position where they do not interfere with the carry-out work.

Next, the check 783 is rotated by the drive of the prime mover 84, and the standby hooks 82 that have been retracted below the reel receiver 75 lock the parts of both winding creels 50, and are rolled on the standby rails 80. After that, a new take-up reel 5 is supported on the reel receiver 75 by the return hook 78 from the return rack 77, and the take-up reel 5 is moved to the standby position and stopped there. The belt 47, the carry-out conveyor 36, and the sliding frame 53 are returned to the above-described winding state, and the original veneer veneer 1, which has been cut relatively thinly from the original veneer veneer portion 17, is transferred to a new take-up reel. 5.

During the winding process, as shown in FIG. 8, when transitioning from the original veneer veneer section 17 to the inner layer veneer veneer section 18, the cutting is temporarily interrupted and the winding operation is also stopped. However, as described above, the winding guide member 74 is inserted from the top surface thereof.
The rolled balls 6 with the opened balls are transferred to a transfer wheel 10 at the upper stage of the rolled balls stock area 9. During this time, the pedestal 21, take-up guide belt 47, and unloading conveyor 36 are opened to positions where they do not interfere with the loading work.

Next, the chain 783 is reversely rotated by the prime mover 84, and the take-up reel 5 in the standby position is engaged with the standby hook 82.
The reel is rolled on the standby rail 80 up to the reel receiver 75. Thereafter, the side drive roll 4, the winding guide belt 47, the winding guide member 7
4, etc., and the medium plate veneer veneer 1 cut relatively thickly from the medium plate veneer veneer portion 18 of the inner layer is wound again onto the winding ball 6 which is in the process of being wound. .

Thereafter, the above operations are repeated until the rolled ball 6 reaches the desired diameter, and when the rolled ball 6 reaches the desired diameter, it is transferred to the lower transfer rail 10 of the rolled ball stock area 9 via the lifting device 7.

Thus, the winding IJ-rule 5 and the winding bobbin 6 are wound around the side surface of the veneer veneer 1 on the unloading side by the cooperative action of the winding guide belt 47 and the veneer veneer introducing member 39, and 74, the veneer veneer 1 is wrapped around the veneer veneer 1 from its outer circumferential top surface to the vicinity of the introduction port of the veneer veneer 1, so that the veneer veneer 1 being conveyed is automatically introduced into the winding reel 5 and wound up to a desired diameter. It is.

"Effects" As described above, according to the present invention, the carry-in conveyor and the side drive rolls are arranged side by side on a frame with the starting end of the veneer veneer carry-in side as a fulcrum, and the side drive rolls are erected at the extended positions on both sides. A reel support is attached to the reel support, and a take-up reel that rotates in pressure contact with the side drive roll is supported on the reel support, and a standby position is provided at an arbitrary distance from the vicinity of the reel support to the plywood veneer delivery side. A pair of standby rails on which the rollers at both ends of the take-up reel roll are disposed between them, and standby hooks movable along the standby rails are engaged with both shafts of the take-up reel. Therefore, it is possible to wind up a veneer veneer roll of the same thickness while temporarily waiting at the standby position until it reaches a desired diameter. Therefore, the winding rate for one winding reel increases, and accordingly, the time required for replacing the winding reel can be shortened and work efficiency can be improved.

Furthermore, when unwinding a veneer veneer to a veneer dryer, in the past, the amount of unwinding of spools that did not reach a desired diameter was small, and the empty winding series after unwinding and the spools to be rewound next During this period, the filling rate of the veneer veneer into the veneer dryer decreased due to the increased number of replacements of the veneer. However, according to the present invention, since each rolled ball has an arbitrary diameter, it is possible to avoid a decrease in the filling rate. become.
