Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a veneer veneer which has been cut by a veneer lace or a veneer veneer which has been dried by drying a veneer veneer. TECHNICAL FIELD The present invention relates to a winding method and an apparatus for smoothly winding a winding reel while suppressing the occurrence of cracks and tears.

[0002]

2. Description of the Related Art Conventionally, veneer veneers cut by veneer lace are usually conveyed by a conveyor to a veneer veneer winding position. At the veneer veneer winding position, the side conveyor roll having the same conveying surface as the conveying conveyor, and the take-up reel rotatably supported at a position immediately above the conveying conveyor are maintained in a state where they are pressed against each other. I have. When the side drive roll is rotated at substantially the same speed as the conveyor, the take-up reel is driven in a linear contact state with this rotational force, and the veneer veneer conveyed on the conveyor is wound around the take-up reel. taking it.

[0003] Usually, the veneer veneer to be wound has a width of 6 to 8 feet.
In order to wind these long veneer veneers, the winding reel and the side drive roll need to be longer. At this time, assuming that the long side drive roll and the take-up reel do not bend in the axial direction, and that the veneer veneer itself has a uniform thickness, the veneer veneer has a side drive roll or The load on the take-up reel is linear.

[0004] This load is uniform at any part in contact with the side drive roll and the take-up reel, and the linear pressure per unit acting on each part is obtained by dividing the load of the side drive roll or the take-up reel by the line length. Calculated value.

[0005]

However, since both the side drive roll and the take-up reel are supported at both ends thereof, the side drive roll located below the axial center thereof has a side drive roll. The drive roll has undergone its own weight deflection and load deflection. In addition, the take-up reel located above has its own weight bent. Therefore, the degree of bending of both tends to be slightly larger for the lower side drive roll than for the upper take-up reel. For this reason, in a normal state, the opposing surfaces of the side drive roll and the take-up reel are not uniformly in contact with each other in the axial direction, and a shortage of load occurs in the central portion in the axial direction.

[0006] Under such circumstances, the veneer veneer conveyed on the conveyor is pressed by the roll linear pressure of the side drive roll, and is taken up by the take-up reel that rotates following. . At this time, it is desirable that a linear pressure is evenly applied on a line perpendicular to the transport direction of the veneer veneer, but a shortage of load occurs near each central portion of the side drive roll and the take-up reel. For this reason, the veneer veneer is wound on the take-up reel in the vicinity of the central portion orthogonal to the transport direction without applying an initial linear pressure per unit.

As described above, if the linear pressure required for winding the veneer veneer is reduced only in the area where the side drive roll and the take-up reel are not in contact with the intended load, the linear pressure required for winding the veneer veneer can be reduced. In addition, the pressing pressure of the side drive roll against the take-up reel is insufficient. Furthermore, since the contact portion between the side drive roll and the take-up reel is unspecified, stability in continuous winding of the veneer veneer onto the take-up reel is lacking.

On the other hand, in veneer veneers cut by veneer lace, immediately after cutting or during the transportation, unevenness, waving, twisting, etc., due to contraction of fibers are not a little generated. These are remarkable depending on the tree species of the raw wood, and may be broken from the direction of the fiber on the conveyor or during winding of the veneer veneer. If the torn veneer veneer rotates with the inertia associated with the rotation of the take-up reel, that is, the side drive roll is pressed against the take-up reel, the take-up reel rotates in the opposite direction to the veneer veneer. May be taken up by the co-rotating force for winding up, but since the torn portion is folded and wound up, the winding up operation is temporarily interrupted.

Further, if the veneer veneer to be wound is dried, the fiber has a higher rigidity than a veneer veneer in a wet state. For this reason, depending on the type of veneer veneer, it may be difficult to wind the side drive roll along the curvature of the take-up reel with only a linear pressing force against the take-up reel. In particular, if cracks, cuts, and the like that occur after drying are present in the veneer veneer, the veneer is likely to be torn from the veneer, and the winding operation must be interrupted.

Accordingly, the present invention provides a veneer veneer cut by a veneer lace or a veneer veneer after drying the veneer veneer in a wet state with a veneer drier. It is intended to provide a winding method and a winding apparatus for winding the same smoothly on a winding reel while suppressing the occurrence of the like.

[0011]

Means for Solving the Problems and Effects of the Invention In order to solve the above problems, a method for winding a veneer veneer according to the present invention is a method for winding a veneer veneer, which is rotatably supported at a veneer veneer winding position. In the axial direction, a plurality of rows of winding guide members are opposed at arbitrary intervals, and when the veneer veneer is conveyed on the conveyor, the winding is located on the side opposite to the side where the veneer veneer is loaded. A veneer veneer is wound on a take-up reel by setting a take-up guide member, which rotates at substantially the same speed as the transport conveyor, along the curvature of a part of the outer periphery of the reel.

A veneer veneer in a wet state cut by a veneer race or a veneer veneer dried by a veneer drier is transported on a transport conveyor to a veneer veneer winding position. In this case, the veneer veneer may be in the form of a cut sheet cut parallel to its fibers at a fixed length, or may be continuous. At the veneer veneer take-up position, a plurality of take-up guide members are provided at arbitrary intervals in the axial direction of the take-up reel. When the veneer veneer is wound, the take-up guide member is in a state of being in close contact with a part of the outer periphery of the take-up reel from a position below the take-up reel to a side opposite to a side where the veneer veneer is loaded. Is done.

When the veneer veneer is wound, the take-up guide member is controlled at substantially the same speed as the transport speed of the conveyor, and the veneer veneer transferred from the transport conveyor onto the take-up guide member is taken up by the curvature of the take-up reel. It can be rolled up in a surface state following the image. In particular, in a cut sheet veneer veneer, a plurality of rows of take-up guide members are closely adhered to a part of the outer periphery of the take-up reel in a planar manner along the curvature thereof, so that the winding guide member is securely wound around the take-up reel. You can make it.
Even if the veneer veneer to be wound has been dried and the fiber rigidity is stronger than that of the veneer veneer in a wet state, the winding guide member may be used to form a planar surface on the outer peripheral surface of the take-up reel. It is possible to wrap it around.

At this time, the distance between the rows of the winding guide members arranged in a plurality of rows in the axial direction of the winding reel is determined.
A thread member wound around a veneer veneer as a guide can be fed into the take-up reel, and can be wound by a plurality of rows of thread members in the axial direction of the take-up reel. For this reason, even after the veneer veneer is wound around the take-up reel, even if the close contact with the take-up guide member is released, a plurality of rows of thread members are wound around the veneer veneer as a guide from the top thereof over a plurality of rows. Therefore, the winding posture of the veneer veneer does not shift.

[0015] Even if the veneer veneer to be wound is continuous, the veneer veneer is easily torn due to cracks, cuts, and the like (the veneer veneer after drying tends to occur more often). In the case where the central portion of the wound ball in the course of winding is loose, a stable winding can be performed by feeding a plurality of rows of thread members as guides when winding veneer veneer as described above. .

Although the winding guide members are arranged in a plurality of rows in the axial direction of the winding reel, the winding guide members of each row can be separately and independently pressed under a certain pressure.
Or he is in tension by pulling. Therefore, even if, for example, the take-up reel is bent by its own weight or the veneer veneer has a different thickness, the take-up guide members in each row are maintained in the same tension state. For this reason, the winding guide member can apply substantially the same frictional force to the veneer veneer and follow the curvature of the winding reel, thereby performing a stable winding operation.

In order to solve the above-mentioned problems, a first configuration of a veneer veneer take-up device according to the present invention includes: a take-up reel rotatably supported at a veneer veneer take-up position; A winding guide member wound around the winding guide member in a plurality of rows at an arbitrary interval in the axial direction at a position opposed to the winding guide member, and rotation transmitting means for applying rotation to wind the veneer veneer around the winding guide member. Follow-up means for causing the take-up guide member to follow a part of the outer periphery of the take-up reel according to the curvature thereof; and a take-up reel linked to the take-up guide member at a position below the take-up reel. And a transport conveyor for transporting the veneer veneer between the winding guide members, and at least tensioning means for applying tension to the winding guide member in order to wind the veneer veneer to be wound on a take-up reel. That And butterflies.

A take-up reel rotatably supported at a veneer veneer take-up position, and a plurality of rows wound around a position facing the take-up reel at arbitrary intervals in the axial direction of the take-up reel. And at least a winding guide member. If the reel receiving position bearing the take-up reel is fixed, the transfer conveyor and the winding guide member can be pivoted downward with the starting point of the transfer conveyor for transferring the veneer veneer as a fulcrum. It has a configuration. In order to be able to turn freely, a member that turns by fluid movement or balance weight is supported at a constant pressure, and this winding is increased by the radius of the winding diameter that increases with winding of veneer veneer. The winding guide member pressed against the surface of the veneer veneer to be taken is automatically turned and lowered together with the conveyor.

Conversely, if the position where the take-up guide member is rotatably supported is fixed, the reel receiving position of the take-up reel is raised by the radius of the increasing take-up diameter. As a mechanism for raising the reel receiving position, for example, the reel receivers at both ends supporting the take-up reel are connected to the feed shaft, and the take-up reel detects the thickness of the veneer veneer to be taken up. This is based on the fact that the feed shaft is moved forward by the detected thickness every time one rotation is made to raise the reel receivers at both ends.

The take-up guide member is opposed to the outer peripheral position of the take-up reel from a position below the take-up reel to a side opposite to the side where the veneer veneer is loaded. Then, at the time of winding the veneer veneer, the follow-up means is pivoted to, for example, the take-up reel side, and a plurality of take-up guide members arranged in the axial direction of the take-up reel are arranged on the outer periphery of the take-up reel. Comes into close contact with a part of the surface.

This winding guide member is constituted by, for example, a plurality of rows of endless belts wound around pulleys located at at least three points of a base end, an intermediate portion and a tip end. Each endless belt is linked to a leading end of a transport conveyor that transports veneer veneers at a pulley at a base end thereof. When the follower turns the pulley at the end in the direction of the take-up reel, the pulley is pressed against a part of the outer periphery of the take-up reel according to its curvature.

Further, the winding guide member may have the following form in addition to the above-described form. That is,
The lower end of the veneer veneer winding position is a base end, the tip is a free end, and a plurality of endless bands are wound around pulleys located at both ends. Each endless belt is linked to a leading end of a transport conveyor that transports veneer veneers at a pulley at a base end thereof. When the follower turns the pulley at the end in the direction of the take-up reel, the pulley is pressed against a part of the outer periphery of the take-up reel according to its curvature.

Each endless belt has a belt-like shape endlessly stretched between a pulley at the base end and a pulley at the tip end, but is not stretched between pulleys having the same diameter. The diameter of the pulley at the proximal end is larger than that of the pulley at the distal end.
Therefore, when the endless belt is pressed against the lower part of the outer periphery of the take-up reel by a difference in radius between the respective pulleys, there is a margin, and the endless band can be pressed with a certain width on the lower part of the outer periphery of the take-up reel. By pressing on this surface, the surface contact area between the endless belt and the lower part of the take-up reel is increased, so that more frictional force can be generated and the veneer veneer can be stably applied to the take-up reel. It becomes possible to wind up. Furthermore, since the supporting arms supporting the pulley at the base end and the pulley at the tip are bent upward from the intermediate region toward the end, the diameter of the wound ball increases as the winding progresses. Inconveniences such as the lower end of the upper track of each endless band and the upper end of the support arm interfering with each other or stopping the endless band from rotating are avoided, and the winding of the veneer veneer onto the take-up reel is ensured. I have.

In the direction of the axis of the take-up reel, a plurality of thread member feeding mechanisms for feeding a thread member wound as a guide for winding veneer veneer onto the take-up reel are provided at arbitrary intervals. I have. For example, a yarn feeding mechanism is disposed within an interval between each row of the winding guide members, and the leading end of the yarn member fed from each of the winding wheels of the yarn member feeding mechanism to the winding reel extends in the longitudinal direction thereof. At a plurality of locations at an arbitrary interval, and wound around a plurality of locations on the veneer veneer with the thread member as a guide and wound on a take-up reel.

When the take-up guide member is pressed against a part of the outer periphery of the take-up reel according to the curvature thereof, the take-up guide member is in the endless belt constituting the take-up guide member while allowing its rotational force. A rotating pulley that is pressed or pulled under pressure is provided to maintain the winding guide member in a constant tension state. Therefore, the winding guide member can apply substantially the same frictional force to the veneer veneer to conform to the curvature of the winding reel, thereby performing a stable winding operation.

In particular, the rotating pulleys are individually mounted so as to be pressed or pulled under a certain pressure against each of the endless belts comprising a plurality of rows constituting the winding guide member while allowing the rotating force. It is also possible. In this way, if independent tensioning means is installed in each endless belt, for example, the take-up reel may be bent by its own weight,
Even if the veneer veneer has a difference in thickness, the winding guide members in each row are maintained in the same tension state, and the same is applied to the veneer veneer at any position in the axial direction of the take-up reel. It is possible to provide a frictional force.

[0027] The diameter of the take-up reel is adjusted so that the curvature is reduced so that cracks from a portion parallel to the fiber, which occur when the dried veneer veneer is wound on the take-up surface of the take-up reel, are reduced. Not less than 85 times the veneer veneer thickness and 300
mm or more. According to the findings of the inventor of the present application, the veneer veneer before drying, that is, the take-up reel (diameter 165 mm) used for winding the veneer veneer immediately after cutting from the raw wood is used for the veneer veneer after drying. If used for winding as it is, it will not adapt to its small diameter, and the smaller the curvature compared to the thickness of the veneer, the more likely it will be to crack from the part parallel to the fiber and wind it around the winding reel itself It was often impossible. In particular, cracks that occur after drying,
If a cut or the like exists in the veneer veneer, the veneer will be torn from the portion. The present inventors have found from experiments that the diameter of a take-up reel for winding a veneer veneer after drying is 300 mm.
mm or more, and a diameter having a curvature corresponding to the thickness of the veneer veneer to be wound was obtained by the formula of diameter D of take-up reel / thickness T of veneer veneer to be wound. According to these, by setting the diameter of the take-up reel to be at least 85 times the thickness of the veneer veneer and at least 300 mm, the veneer veneer after drying can be wound well.

Further, the take-up reel is provided with a ventilation communicating portion in which a take-up surface on which the veneer veneer is taken up is radially communicated with a gap formed inside the reel, and a plurality of the wind-up reels are provided in the axial direction of the reel shaft. It is also possible to configure so that an opening communicating with the gap is formed in the supporting portion for winding the veneer veneer individually attached. According to this configuration, it is possible to reduce the weight of the take-up reel itself, and to reduce the power burden when the take-up reel is transported, when veneer veneer is wound, and when the reeling deck is stored in the roll stock area. Reduction can be achieved. In addition, the veneer veneer wound on the winding surface of the take-up reel is radially communicated with a gap formed inside the take-up reel through a ventilation communication portion, and is connected to the reel shaft. An opening is formed in the supporting portion for winding the veneer veneer attached, and the gap is communicated in the axial direction, so that the winding surface of the veneer veneer, the gap inside the take-up reel, and the atmosphere outside the take-up reel. And the communication state,
Air permeability will be achieved. Therefore, it is possible to diffuse hot air, moisture, and the like inherent in the veneer veneer after drying into the atmosphere from a number of openings, thereby promoting equilibrium moisture content while storing the wound veneer veneer. .

As a preferred example, the take-up reel is provided with a plurality of flanges having the same diameter in the axial direction of the reel shaft at arbitrary intervals, and the outer periphery of each flange is wound with a veneer veneer. It has a winding surface. In other words, this take-up reel has flanges attached to the reel shaft by welding or the like at regular intervals in the axial direction thereof, and serves as a support portion for winding veneer veneer, and the outer peripheral surfaces of these flanges are used as veneer veneer plates. A winding surface is provided, and a plurality of openings are formed in each of these flanges radially from the shaft portion. In this take-up reel, each flange within a length interval corresponding to the take-up width of the veneer veneer is used as a take-up support portion of the veneer veneer, wound on the take-up reel, and wound into a ball. You. At this time, the air in each flange interval is radiated to the atmosphere from the flange openings located on both sides through each opening formed in each flange. Therefore, the hot air, moisture, etc., which are present in the veneer veneer after drying, are radiated to the atmosphere from the flange openings located on both sides through the respective openings from within the respective flange intervals, and conversely, fresh air from the atmosphere is obtained. Flows into the take-up reel from the opening of each flange.

As another preferred form of the take-up reel, a plurality of flanges having the same diameter are attached to the reel shaft at arbitrary intervals in the axial direction thereof, and the veneer veneer is wound. Body plate serving as a winding surface is fixed along the curvature. That is, disk-shaped reinforcing plates are attached to the reel shaft by welding or the like at regular intervals in the axial direction of the reel shaft. A flat plate having a width several times or more the thickness of the reinforcing plate is wound around the outer periphery of the reinforcing plate and fixed by welding or the like to form a so-called flange. The outer diameters of these flanges are the same, and a body plate serving as a winding surface for winding a veneer veneer is wound around the outer periphery thereof along its curvature and fixed by welding or the like. A plurality of openings are radially formed in each flange, and a large number of openings are also formed in the body plate.

In the radial direction of the take-up reel, the veneer veneer communicates with the void formed inside the reel through a number of openings formed in the body plate. Also,
In the axial direction, a gap formed between the flanges through an opening formed in each flange communicates with the atmosphere outside the take-up reel. Therefore, it is possible to allow air to flow into the take-up reel from each opening formed in each flange and body plate, and conversely, to allow air inside the take-up reel to flow out from each opening in the flange and body plate to the atmosphere. Become. For this reason, even if hot air, moisture, and the like, which are present in the veneer veneer after drying, flow into the inside of the take-up reel from a large number of openings formed in the body plate, the hot air and moisture pass through each opening of each flange and are on both sides. Is released to the atmosphere from each opening of the body plate where the veneer or veneer veneer is not wound.
In addition, fresh air from the atmosphere, each opening of the collar on both sides,
Alternatively, the veneer wound into the take-up reel flows from each opening of the body plate where the veneer veneer is not wound, passes through each opening of each flange, and passes through each opening of the body plate. It will come in contact with the veneer. In this manner, hot air, moisture, and the like, which are present in the veneer veneer after drying, do not stay inside the take-up reel, and can always be replaced with fresh air.

In order to solve the above-mentioned problems, a second configuration of the veneer veneer winding apparatus according to the present invention includes a connection conveyor provided with a pulse transmitter and a dried conveyor conveyed on the connection conveyor. A detector for detecting a veneer veneer, a distance setting device for setting a distance from the detector position to a winding guide member located downstream, a drive controller for controlling driving of the winding guide member, and a winding controller. A take-up reel that rotates in contact with the upper surface of the take-up guide member, and when detecting a veneer veneer conveyed on the connection conveyor, stops the drive of the take-up guide member by a command from the drive controller, When the pulse amount of the set distance is counted up, the winding guide member is driven to wind the veneer veneer around the winding reel.

Generally, veneer veneers in the form of cut sheets conveyed on a conveyor are conveyed at regular or irregular intervals in front and rear. If a veneer veneer is wound around a take-up reel with a front-rear interval, the take-up efficiency deteriorates or the winding mode becomes irregular. For this reason, there is a case where the cut sheet-shaped veneer veneer is wound around a take-up reel while narrowing a gap between the front and rear spaces in consideration of the winding efficiency and in order to improve the winding mode.

That is, a non-contact detector such as a contact type, a transmission type, and a reflection type, which is installed on a transport conveyor,
When the front end portion of the veneer veneer is detected, this detection command is transmitted to a drive controller which is a control system of the winding guide member. The drive controller is connected to a distance setting device that sets the distance from the detector to the winding guide member, and stops the rotation of the winding guide member based on the detection command. A pulse transmitter is installed on the conveyor, and the veneer veneer is conveyed over the conveyor, and this is detected by counting up the pulse amount. The veneer veneer that has reached the take-up guide member is wound around the take-up reel by using the thread member as a guide by driving the take-up guide member by the length of the plate. This plate length is based on the fact that the detector detects the front end and the rear end of the veneer veneer when the veneer veneer is conveyed on the conveyer, and captures this as a pulse amount in the drive controller. Since the plate length is cut into a substantially fixed length, the fixed length may be stored in the drive controller in advance as the plate length. When the front end of the next veneer veneer is detected by the detector, the veneer veneer reaches the winding guide member and fills the gap with the rear end of the veneer veneer previously wound, using the thread member as a guide. Wound on a take-up reel. By repeating the above work,
The take-up guide member rotates intermittently, and the veneer veneer can be efficiently taken up on the take-up reel with the front-rear space being tight.

Each of the pair of support arms 27 has a support portion 32 formed in an intermediate region thereof, and a bearing surface attached to the support portion is mounted on the intermediate shaft 21.

Therefore, each endless belt 18 is wound around the pulley 19 at the base end, the pulley 22 at the middle part, the pulley 25 at the upper part, and the pulley 26 at the tip end in this order to form an endless belt. The rotation of the motor 33 installed at one end of the intermediate shaft 21 is passively controlled to control the rotation of the conveyor 1 and the winding guide member 17 at substantially the same speed. When each of the pair of support arms 27 is pivoted by the follow-up fluid cylinder 30 in the direction of the take-up reel 7 about the support portion 32 mounted on the intermediate shaft 21 via the bearing surface, each of the pair of support arms 27 is rotated. The pulley 26 at the distal end located at the distal end of the support arm 27 is in contact with the outer periphery of the take-up reel 7, and the take-up guide member 17 is pressed against a part of the outer periphery of the take-up reel 7 in a planar shape following the curvature thereof. State.

In the axial direction of the take-up reel 7, a thread member transfer mechanism 35 for transferring a thread member 34 wound as a guide for winding the veneer veneer 9 onto the take-up reel 7 is provided at an arbitrary interval. Several are installed.
For example, a yarn drawing-in mechanism 35 is arranged in each row of the winding guide member 17, and the nozzle 36 of the yarn member 34 is attached to a substantially intermediate region of the support arm 27.
On the other hand, in order to entangle the thread member 34 with the take-up reel 7, sandpaper that entangles the thread member 34 is attached to the take-up reel 7 at a plurality of locations at arbitrary intervals along the longitudinal direction. Or a high friction region such as a knurled projection.

The winding guide member 17 is pressed against the endless belt 18 constituting the winding guide member 17 while allowing the rotational force of the winding guide member 17,
Alternatively, a rotary pulley 37 to be pulled is provided, and the winding guide member 17 is maintained in a tensioned state with a constant tension. That is, as shown in FIGS. 3 and 4, an L-shaped lever according to the number of rows of the endless belt 18 constituting the winding guide member 17 in the axial direction of the shaft 38 supported on the gantry 5. Attach 39. The rotating pulley 37 is rotatably supported at an intermediate position where the lever 39 protrudes.

Thus, the winding guide member 17 is in a tension state.

The rotary pulley 37 is connected to a shaft (not shown) inserted at an intermediate position between levers 39 located at both ends.
Alternatively, the lever 39 can be rotatably supported at an arbitrary interval in the axial direction, and the other end of the lever 39 can be attached to the piston rod 41 of the fluid cylinder 40 for tensioning. According to this, each rotary pulley 3 is
7 can act integrally to be in a tensioned state, and the winding guide member 17 can be in a state along the curvature of the winding reel 7. However, as shown in the illustrated example, by installing a tensioning fluid cylinder 40 that individually applies a certain pressure to each of the endless belts 18 that constitute the winding guide member 17, for example, the weight of the winding reel 7 is reduced. Even if bending occurs or the veneer veneer 9 has a difference in thickness, the winding guide members 17 in each row are maintained in the same tension state, and any direction in the axial direction of the winding reel 7 is maintained. It is possible to apply substantially the same frictional force to the veneer veneer 9 at the site.

At the time of winding the veneer veneer 9, first,
The fluid is supplied to the front port of the suspension fluid cylinder 12, and the gantry 5 is moved upward with the leading end portion of the shaft of the start end pulley 2 of the transport conveyor 1 located on the loading side of the veneer veneer 9 as a fulcrum. It is turning. Therefore, the leading end of the gantry 5 rotates together with the conveyor 1 and the winding guide member 17, and the winding guide member 17 comes into contact with the lower surface of the winding reel 7 rotatably supported by the reel receiver 8. Next, the fluid cylinder 30 for follow-up and the fluid cylinder 40 for tension are actuated so that the endless belts 18 constituting the take-up guide member 17 follow the lower surface of the take-up reel 7 and then the veneer veneer 9
Are brought into planar contact with the outer peripheral side opposite to the loading side, and are kept in tension.

In this state, the tip of the thread member 34 unwound from the pinwheel 34s is sprayed through the nozzle 36 onto the high friction region of the take-up reel 7 to be entangled. Then
By rotating the winding guide member 17 at least once, preferably several times, tension is generated between the winding reel 7 with which the thread member 34 is entangled and the thread member 34. Thereafter, the veneer veneer 9 conveyed from the preceding step is transported via the conveyor 1 and the outer periphery of the lower surface of the take-up reel 7 and the winding guide member 1 controlled at substantially the same speed as the conveyor 1.
7 and between. The veneer veneer 9 may be in a wet state cut by a veneer lace (not shown) or in a dry state dried by a veneer drier (not shown). It may be in the form of a cut sheet cut at a fixed length in parallel with the fibers, or may be in the form of a continuous sheet.

The take-up guide member 17 is brought into planar contact with a part of the outer periphery of the take-up reel 7 from the position below the take-up reel 7 to the side opposite to the side where the veneer veneer 9 is carried in. Therefore, the veneer veneer 9 is moved by the frictional force generated by the driving of the take-up guide member 17,
Is rolled in a surface state following the curvature of. At the time of winding the veneer veneer 9, the thread member 34 is in a tension state between the winding reel 7 and the nozzle. Therefore, the veneer veneer 9 drives the winding guide member 17 by the frictional force.
When it is wound on the take-up reel 7, it is wound at a plurality of locations from the tip end thereof by using the thread member 34 as a guide.

In particular, in the cut sheet-shaped veneer veneer 9, the plurality of rows of the winding guide members 17 are in close contact with a part of the outer periphery of the winding reel 7 in a planar manner along the curvature thereof, so that it is ensured. It can be wound around the take-up reel 7. Further, even if the veneer veneer 9 to be wound is dried and its fiber rigidity is stronger than that of the veneer veneer 9 in a wet state, the winding guide member 17 provides the outer periphery of the take-up reel 7. It is possible to follow the surface and wind it.

Further, when the veneer veneer 9 is pressed against the surface of the take-up reel 7 by the take-up guide member 17 in close contact with each of the endless belts 18 constituting the take-up guide member 17, Are wound around the upper surface of the veneer veneer 9 as a guide. Therefore, after winding the veneer veneer 9 around the take-up reel 7, the take-up guide member 17
Even if the close contact state with the veneer is canceled, the winding posture of the veneer veneer 9 does not shift because the plural rows of thread members 34 are wound around the veneer veneer 9 from above as a guide over the plurality of rows. .

An embodiment in which the veneer veneer 9 in the form of a cut sheet is wound on the take-up reel 7 while taking into account the winding efficiency of the veneer veneer while narrowing the gap between the front and rear sides will be described with reference to FIG. When a contact type detector or a non-contact type detector such as a transmission type or a reflection type which is installed on the conveyor 1 detects the front end portion of the veneer veneer 9, the detection command is transmitted to the winding guide member 17. The signal is transmitted to the drive controller 43 which is a control system. The drive controller 43 is connected to a distance setting device 44 which sets a distance K from the detector 42 to the winding guide member 17. Based on the detection command, the distance setting device 44 is connected to the drive controller 43.
Stop the rotation of. A pulse transmitter 4 is provided on the conveyor 1
The veneer veneer 9 is transported by a distance K on the transport conveyor 1, and this is detected by counting up the pulse amount. The veneer veneer 9 that has reached the take-up guide member 17 is wound around the take-up reel 7 with the thread member 34 as a guide when the take-up guide member 17 is driven by the length of the plate. This board length is
This is because when the veneer veneer 9 is conveyed on the conveyor 1, the detector 42 detects the front end and the rear end of the veneer veneer 9 and captures them as pulse amounts in the drive controller 43. still,
Since the plate length is cut into a substantially fixed length, the fixed length may be stored in advance in the drive controller 43 as the plate length. The next veneer veneer 9 has a detector 42 at the front end.
Is detected on the winding guide member 17 through the same steps as described above, and the veneer veneer 9 wound previously is wound.
Is wound around the take-up reel 7 using the thread member 34 as a guide in a state where the gap with the rear end is reduced. By repeating the above operation, the take-up guide member 17 rotates intermittently, and the veneer veneer 9 can be efficiently taken up on the take-up reel 7 with the front-rear space being tight.

Even if the veneer veneer 9 to be wound is continuous, the veneer veneer 9 tends to be torn due to cracks, cuts and the like (a tendency to occur frequently in the veneer veneer 9 after drying). In the case where the central part of the wound ball in the course of winding is loose, a plurality of rows of thread members 34 are fed in as a guide for winding the veneer veneer 9 as described above, so that stable winding can be achieved. It can be performed.

During the winding of the veneer veneer 9, the individual endless belts 18 constituting the winding guide member 17 are maintained in tension by applying substantially the same pressure by the individually arranged rotary pulleys 37. Therefore, for example, even if the take-up reel 7 is bent by its own weight or the veneer veneer 9 has a difference in thickness, the winding guide members 17 in each row are maintained in the same tension state. It is possible to apply substantially the same frictional force to the veneer veneer 9 at any position in the axial direction of the take-up reel 7.

As the veneer veneer 9 is wound on the take-up reel 7 and the diameter of the wound ball 46 increases, the leading end of the gantry 5 is pivoted about the axis of the start end pulley 2 of the conveyor 1 as a fulcrum. It will be turned downward by the increase in diameter. That is, since the position of the reel receiver 8 bearing the take-up reel 7 is fixed, the wound ball 46 overcomes the fluid pressure of the suspension fluid cylinder 12 by an increase in the diameter thereof.
The gantry 5 is pushed down via the winding guide member 17. Further, as the diameter of the wound ball 46 increases, the position of the pulley 26 at the leading end of the winding guide member 17 also gradually rises by overcoming the fluid pressure of the following fluid cylinder 30 (see FIGS. 3 and 4). Clockwise movement). further,
With the increase in the diameter of the winding ball 46, the position of the rotary pulley 37, which individually presses and tensions the winding guide member 17, also overcomes the fluid pressure of the tensioning fluid cylinder 40 and is individually displaced. Become. These are clear from the comparison between the winding start position of the veneer veneer 9 shown in FIG. 3 and the winding progress position shown in FIG.

In addition to the above-described configuration, the winding guide member 17 has a base end below the winding position of the veneer veneer 9 as shown in FIG. It is also possible to constitute by a plurality of rows of endless belts 18 wound around the pulleys respectively. That is, at a position below the veneer veneer 9 winding position, a proximal shaft 47 is rotatably supported in front of the shaft 20 of the distal pulley 3 of the transport conveyor 1, and the proximal shaft 47 in the axial direction of the proximal shaft 47 is supported. A link pulley (not shown) is attached at a position where the phase matches the tip pulley 3, and the link conveyor 55 is wound.
On the other hand, a plurality of proximal pulleys 48 are attached to the proximal shaft 47 at arbitrary intervals in the axial direction. A pair of support arms 49 that are bent upward from the intermediate region toward the distal end are rotatably supported on both sides of the proximal end pulley 48 on the proximal end shaft 47. Each of the small-diameter distal pulleys 50 is rotatably supported within the distal interval of the pair of support arms 49, and the endless belt 18 such as a belt is stretched between the proximal pulley 48 and the small-diameter distal pulley 50. Arbitrary positions of the support arms 49 are integrally connected by a connecting beam 51, and both ends of the connecting beam 51 are attached to the piston rod 31 of the following fluid cylinder 30 pivotally supported by the gantry 5.

Each endless belt 18 is a belt-like belt that is endlessly stretched between a base end pulley 48 and a distal end pulley 50, but is not a belt that is stretched between equal-diameter pulleys. The end pulley 48 has a larger diameter than the pulley at the tip. Accordingly, the endless belt 18 is provided by the radius difference of each pulley.
Is pressed against the lower part of the outer periphery of the take-up reel 7, so that the endless belt 18 can be pressed against the lower part of the outer periphery of the take-up reel 7 with a certain width. By pressing in this plane, the planar contact area between the endless belt 18 and the lower part of the take-up reel 7 can be increased, and more frictional force can be generated. Can be stably wound up. Further, since the supporting arm 49 supporting the base pulley 48 and the tip pulley 50 is formed to be bent upward from the intermediate region toward the front end, the diameter of the wound ball 46 increases as the winding progresses. As a result, inconveniences such as the lower end of the upper track of each endless belt 18 and the upper end of the support arm 49 interfering with each other and stopping the endless belt 18 from rotating are avoided, and veneer veneers to the take-up reel 7 are avoided. 9 is ensured.

In the present embodiment, the gantry 5 is pivotable by the fluid cylinder 12 for suspension. However, it is also possible to support the pivotable member with a constant pressure by a balance weight or the like. is there. In addition, the position of the take-up reel 7 can be freely raised and lowered, and conversely, the position where the take-up guide member 17 is rotatably supported can be fixed. As a mechanism for raising the position of the reel receiver 8, for example, as shown in FIG. 6, the reel receivers 8 at both ends supporting the take-up reel 7 are connected to the step feed shaft 52 and connected to the step feed shaft 52. The stepping shaft can be rotated by the motor 53 that has been set. On the other hand, a band-shaped line sensor 54 for detecting the diameter of the wound ball 46 is provided on the reel support 6.
Therefore, by detecting the thickness of the veneer veneer 9 to be wound,
Every time the take-up reel 7 makes one rotation, the step feed shaft 52 is stepped by the motor 53 by the detected thickness to raise the reel receivers 8 at both ends.

When the veneer veneer 9 is formed into a roll 46, if the veneer veneer 9 is wet, the take-up reel 7 having a diameter of 165 mm, which has been used for conventional winding, is used.
Can be used as it is. However, the veneer veneer 9 after drying is placed on the take-up reel 7 having a diameter of 165 mm.
When wound on the take-up reel 7, it is often difficult to wind the take-up reel 7 itself, since it does not adapt to its small diameter and tends to crack from a portion parallel to the fiber. In particular, if cracks, cuts, and the like that occur after drying are present in the veneer veneer 9, the veneer veneer 9 will be torn from the portion. The present inventors have found from experiments that the diameter of the take-up reel 7 for winding the veneer veneer 9 after drying is set to 300 mm or more, while the curvature is determined according to the thickness of the veneer veneer 9 to be wound. The diameter was obtained by the formula of diameter D of take-up reel 7 / thickness T of veneer veneer 9 to be wound. According to these, the diameter of the take-up reel 7 is set to 85 of the thickness of the veneer veneer 9.
By setting it to twice or more and 300 mm or more, the veneer veneer 9 after drying can be taken up well. For example, if the thickness of the veneer veneer 9 is 2 mm, the diameter D of the take-up reel 7 is set to 170 mm from the above formula.
Since this value is less than 300 mm, the diameter of the take-up reel 7 is 300 mm or more. Accordingly, the diameter of the take-up reel 7 obtained by converting the dried veneer veneer 9 into a roll 46 is 30
In this embodiment, a take-up reel 7 having a diameter of 0 mm or more and a diameter of 450 mm was used.

The take-up reel 7 is cylindrical with the shaft 7G as the center of rotation, and is normally closed by a welding structure. In particular, the take-up reel 7 has a larger diameter (300 mm or more, in this embodiment) than the take-up reel (diameter 165 mm) conventionally used for winding veneer veneer 9 immediately after cutting from a log. Is 450 mm), so the weight of the take-up reel 7 itself increases, and this increases when the take-up reel 7 is transported, when the veneer veneer 9 is wound, and when the reel is stored in the reel stock area of the reeling deck. It also reinforces the structure, such as the power burden or the reeling deck.

FIGS. 8 and 9 show other embodiments of the take-up reel 7 according to the present invention.
That is, a large number of slit-shaped openings 7K are provided on the outer surface of the large-diameter take-up reel 7 shown in FIG. 8, and the large-diameter take-up reel 7 shown in FIG. A plurality of large-diameter flanges 7T having the same diameter are provided at arbitrary intervals in the axial direction, and openings 7K are formed in the surface portion of each flange 7T as necessary.

FIG. 10 shows the take-up reel 7 shown in FIG.
A cross section parallel to the axis direction of the example is illustrated. That is, disk-shaped reinforcing plates 7H are attached to the reel shaft 7G by welding or the like at regular intervals in the axial direction of the reel shaft 7G. A flat plate 7I having a width several times or more the thickness of the reinforcing plate 7H is wound around the outer periphery of the reinforcing plate 7H and fixed by welding or the like.
T. The outer diameter of these flanges 7T is the same,
A body plate 7D serving as a body portion of a take-up reel 7 for winding the veneer veneer 9 is wound around the outer circumference thereof along its curvature, and is fixed by welding or the like.

As shown in FIG. 11, a plurality of openings 7K are formed radially in the flange 7T.
D also has a large number of openings 7K as shown in FIG. Therefore, the inside of the take-up reel 7 and the atmosphere are in communication with each other, and the air flows into the take-up reel 7 from the openings 7K formed in the flange 7T and the body plate 7D. Air is applied to each opening 7 of the flange 7T and the body plate 7D.
Outflow from K to the atmosphere is possible. The opening 7K is
In the present embodiment, a slit shape is adopted, but the shape is not limited to this shape, and any shape can be used as long as an opening state such as a circular shape, an elliptical shape, and a polygonal shape can be formed.

FIG. 12 shows the take-up reel 7 shown in FIG.
A cross section parallel to the axis direction of the example is illustrated. That is, in the take-up reel 7, flanges 7T are attached to the reel shaft 7G by welding or the like at regular intervals in the axial direction thereof, and a plurality of openings 7K are formed in each of the flanges 7T. The outer periphery of 7T is configured as a body of the reel. In this case, the fiber direction of the veneer veneer 9 to be wound is parallel to the winding width 1W direction, and the veneer veneer 9 has some strength in the fiber direction.
The winding support of the veneer veneer 9 can be constituted by the outer peripheral portion of each flange 7T. In the take-up reel 7, each flange 7 </ b> T within a length interval corresponding to the take-up width 1 W of the veneer veneer 9 is used as a take-up support portion of the veneer veneer 9, and is taken up by the take-up reel 7. To form a roll ball 9. At this time, the air within the interval between the flanges 7T flows through the openings 7K formed in the flanges 7T, and the flanges 7T located on both sides.
From the opening 7K.

Therefore, according to these take-up reels 7, the weight can be reduced, and the above-mentioned power burden, reinforcement and the like can be eliminated. The veneer veneer 9 wound on the large-diameter take-up reel 7 passes through many openings 7K formed in the take-up reel 7 so that the inside of the take-up reel 7 is in communication with the atmosphere. Nature is achieved. That is, according to the take-up reel 7 shown in FIGS. 8, 10 and 11, hot air, moisture and the like contained in the veneer veneer 9 after drying are taken up from the openings 7K formed in the body plate 7D in large numbers. Even if it flows into the inside of the reel 7, it is radiated to the atmosphere from the flanges 7T located on both sides through the respective openings 7K of the flange 7T or from the respective openings K of the body plate 7D on which the veneer veneer 9 is not wound. Is done. Fresh air from the atmosphere is taken up from each of the openings 7K of the flanges 7T on both sides or each of the openings K of the body plate 7D on which the veneer veneer 9 is not wound.
And passes through each opening 7K of each flange 7T and comes into contact with the veneer veneer 9 wound through each opening 7K of the body plate 7D. Therefore, hot air, moisture, and the like existing in the veneer veneer 9 after drying can always be replaced with fresh air without staying inside the take-up reel 7.

The take-up reel 7 shown in FIGS.
According to this, the hot air, moisture, etc., which are present in the veneer veneer 9 after drying are radiated to the atmosphere from the openings 7K of the flanges 7T located on both sides through the respective openings 7K from within the respective intervals of the flanges 7T. Then, fresh air from the atmosphere flows into the take-up reel 7 from the opening 7K of each flange 7T. In this way, the veneer veneer 9 wound on the take-up reel 7 and becoming the roll 9 promotes the equilibrium moisture content while being stored for a certain time in the roll stock area of the reeling deck. be able to.

In the present embodiment, the flange 7T is formed by winding a flat plate 7I having a width several times or more the thickness of the reinforcing plate 7H around the outer periphery of the disk-shaped reinforcing plate 7H and fixing it by welding or the like. Although described, a state in which the flat plate 7I is not interposed on the outer periphery, that is, a disk-shaped plate may be used.
