Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for winding a veneer veneer. More specifically, the veneer veneer is wound together with the veneer veneer while guiding the veneer veneer to the outer periphery of a winding roll. The present invention relates to a method and an apparatus for winding a veneer veneer.

[0002]

2. Description of the Related Art A method and an apparatus for winding a veneer veneer to be wound together with the above-mentioned wire are disclosed in JP-A-52-1041.
No. 0, "Method and Apparatus for Processing Veneer Veneer", JP-A-52-12908, "Reeling Method and Apparatus for Veneer", or JP-A-56-159101, "Veneer Veneer" Manufacturing method, etc., in which the direction of travel of the veneer veneer is controlled and the wire such as a thread wound on a take-up roll is sequentially fed to the back of the veneer veneer to be wound. The veneer veneers were integrated with each other by the rotation of.

In the above-mentioned prior art, a method of fixing the wire to the take-up roll is employed. The wire is wound around the take-up roll several times in advance, or the wire is wound on the take-up roll with an adhesive tape or the like. And other methods were used.

However, in these methods, each time winding of the veneer veneer is started, the starting end of the wire rod is manually wound around the winding roll together with the starting end of the veneer veneer plate, or the starting end of the wire rod is manually wound in advance. The workability was poor because it was necessary to fasten to the take-up roll.
I could not expect an increase in productivity.

Therefore, Japanese Patent Application Laid-Open No. 57-138901 entitled "Method and Apparatus for Supplying Wire in Veneer Veneer Winding Apparatus" discloses an arrangement in which a winding roll is provided at an appropriate position when starting winding processing. By blowing the wire toward the joint, the engaging portion and the wire are engaged, and the wire is automatically unreeled.

In Japanese Patent Application Laid-Open No. 57-146601, "Method of Supplying Wire in Veneer Single Sheet Winding Apparatus", several enemy needles are appropriately arranged at the wire feeding position of a winding roll. A back-up roll provided with an elastic body or a groove for protecting the needle-shaped body is provided opposite to the outer peripheral surface facing the needle-shaped body, and the end of the wire rod is rotated at the start of the winding process. By blowing air with compressed air toward the vicinity of the needle-shaped body of the take-up shaft and the vicinity of the backup roll, the wire is stuck to the needle-shaped body, and the wire is automatically unreeled. .

However, in the above-described methods, a member for locking the wire must be provided on the take-up roll side, and the conventional take-up roll cannot be used as it is.

On the other hand, in Japanese Patent Application Laid-Open No. 57-142303, entitled "Yarn supply method in a veneer veneer winding apparatus", the end of a wire rod is rotated with a compressed air together with a liquid such as water in the direction of rotation of a winding roll. By sending air in the same close-contact direction as above, the yarn extending linearly by the wind pressure is attached to the winding shaft by the adhesive force of the liquid, and is automatically fed out in sequence. Therefore, there is no need to provide a locking member or the like on the take-up roll side, and there is an advantage that the conventional take-up roll can be used as it is.

[0009]

The above-described conventional veneer winding operation has the following problems. That is, in a conventional manner, the wire rod is wound on a veneer veneer in order to control the traveling direction of the veneer veneer on the back surface of the veneer veneer to be wound and to allow the veneer veneer to be wound on a take-up roll. Since the supply was performed from the back side of the veneer veneer, which is good in the transport direction and below the veneer veneer transport position, after winding is completed, the wire to be transported next must be cut unless the wire is cut. This hindered the transfer of veneer veneers that were not removed.

[0010] For this reason, when the winding is completed, even if the amount of veneer veneer wound on the winding ball is small and there is room for further winding, cutting of one log is completed. Once the log changed, the take-up roll had to be replaced.

[0011] By the way, since the log is a natural thing,
The amount of veneer veneer suitable for winding is different for each log, and if only a small amount of veneer veneer suitable for winding is cut from one log, it is naturally wound on a single reel. Since the amount to be taken is small, it is not desirable from the viewpoint of productivity, workability, and the like, to end the winding as it is and transport the wound ball to the next rewinding step. Accordingly, there has been a demand for adding a veneer veneer suitable for winding to be cut from the next log to the wound ball to perform winding. However, the starting end of the wire rod that had been cut once had to be manually wrapped around the ball or fixed, so that the workability was poor and improvement in productivity could not be expected.

Further, even if the technique of adhering the wire to the take-up roll disclosed in Japanese Patent Application Laid-Open No. 57-142303 is used, it is difficult to automatically attach the wire to the wound ball itself. Therefore, when another veneer veneer is subsequently wound onto a wound ball, the starting end of the wire rod must be again fixed to the wound ball by hand or the like before winding. Was.

As described above, it is not possible to automatically add a veneer veneer, which is cut from the next log after the cutting of one log, to the roll, and to wind it up. Efficiency was low in terms of productivity. Furthermore,
Even if the wire rod is manually wound on a wound ball or fastened, and then another veneer veneer is added and wound up, in the next unwinding step, the wire rod cannot be continuously collected. So I needed another man.

Therefore, an object of the present invention is to start a winding operation without directly fixing the wire material to the winding roll in a winding process which has been conventionally performed almost manually. By controlling the transfer of the veneer veneer, the veneer veneer can be automatically wound on a take-up roll, and if necessary, after the winding of the veneer veneer has been interrupted or terminated, Can be moved to a position separated from the veneer veneer conveyance path and kept in a standby state while holding and fixing the wound ball with the wire material without cutting the wire, and if necessary, another winding can be continued. Winding of veneer veneer using a wire rod that enables new veneer veneer to be continuously wound around the wound ball, automates the veneer veneer winding process, and saves labor and improves productivity. take And to provide a legal and apparatus.

[0015]

According to the first aspect of the present invention, prior to winding the veneer veneer, the winding roll is moved upward from the position above the winding roll toward the veneer veneer conveying direction. The wire is discharged and supplied from the wire supply device together with the fluid so as to block the transport path of the veneer veneer to which the veneer is transported, and then the discharged and supplied wire blocks the transport path of the veneer veneer. While maintaining the above, the wire rod supply device is moved below the winding roll from the lower side of the winding roll in the veneer veneer transport direction, and then the veneer veneer is transported and the veneer veneer is moved together with the wire rod. Was wound up.

According to the second aspect of the present invention, when the wire is discharged and supplied from the wire supply device together with the fluid, the discharge supply amount is controlled by controlling the discharge supply amount of the wire by a capstan roller.

According to the third aspect of the present invention, first, the winding roll having finished winding the veneer veneer is held by pressing the outer peripheral surface of the veneer veneer wound on the winding roll by the wire feeder. While moving the veneer veneer from the transport path of the veneer veneer and once separating it, and then moving the take-up roll again on the veneer veneer transport path, the outer peripheral surface of the veneer veneer by the wire feeder is used. Release the pressure hold on
Then, the subsequent veneer veneer was transported and wound together with the wire.

According to a fourth aspect of the present invention, there is provided a veneer veneer transporting device for transporting veneer veneer, a winding roll provided on the veneer veneer transporting device for winding the veneer veneer, Prior to winding of the veneer veneer, the winding rod is moved upward from the position above the take-up roll in the veneer veneer conveyance direction so as to block the conveyance path of the veneer veneer to which the wire is conveyed. A wire feeder that discharges and supplies a wire together with a fluid, and a wire feeder that feeds the wire in a direction in which the take-up roll transports the veneer veneer while maintaining the state in which the discharged and fed wire obstructs the transport path of the veneer veneer. And a wire feeder moving mechanism that moves from below to below the winding roll.

According to a fifth aspect of the present invention, there is provided an apparatus provided with a capstan roller for controlling a discharge supply amount when discharging the wire together with a fluid from the wire feeder.

[0020]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be outlined with reference to the drawings, and then will be described in more detail. First, FIG. 1 is a schematic side view illustrating a state in which a veneer veneer is wound together with a wire by a veneer veneer winding device 2 (hereinafter simply referred to as a winding device) using a wire. . The winding device 2
Is a wire rod 3, a winding roll 5, a wire rod supply device 7, and a wire rod supply device moving mechanism 71 (hereinafter simply referred to as a movement device).
It has. In FIG. 1, a veneer veneer 1 wound on a take-up roll 5 is obtained by cutting a log with a veneer lace (not shown) in a previous process, and is fed to a winding device by a conveyor belt 11a. Among the veneer veneers, those determined to be suitable for winding are wound on the winding roll 5 together with the wire 3. The winding roll 5 and the veneer veneer 1 wound on the winding roll 5 together with the wire 3 are collectively referred to as a roll 4
I will call it.

Next, as the winding of the veneer veneer 1 progresses, the wire 3 is sequentially supplied from the leading end of the wire feeder 7. At this time, since the wire 3 is sequentially supplied with an appropriate tension applied by a wire tension device 30 described later, the veneer veneer 1 to be wound is brought into close contact with the veneer veneer by the tension of the wire. Can be rolled up.

Reference numeral 9 denotes a capstan roll. Reference numeral 9a denotes a driven roll, which is configured to be able to be pressed against the capstan roll 9 by a pressing member (not shown). As will be described in detail later, the wire 3 is pressed by the driven roll 9a and the capstan roll that is rotationally driven, so that the wire 3 can be fed out by a predetermined amount or the wire 3 can be pulled back by a predetermined amount. In addition, capstan roll 9
Is rotated by a required amount, and a fluid such as compressed air is fed from a fluid supply hose 7e, so that a required amount of the wire 3 can be discharged from the distal end portion of the wire supply device 7.

Next, the wire feeder 7 is provided on the moving device 71 via a wire feeder mount 70. The moving device 71 is for moving the wire rod supply device 7 to a predetermined position.
A mounting base 71g provided so as to be able to move up and down by b is provided. A horizontal cylinder 71 is mounted on the mounting base 71g.
The horizontal cylinder 71a is capable of moving the wire feeder mounting base 70 back and forth in the same direction as the veneer veneer transport direction.

Reference numeral 11b denotes a touch roll for supporting the load of the wound ball 4. Both ends of the touch roll are supported so as to be freely rotatable. If necessary, a roll for rotating the roll 4 by applying a driving force to the touch roll 11b may be used. The outer periphery of the touch roll 11b is baked with urethane rubber. The conveyor belt 11
a and the tip of the wire rod supply device 7
A groove is formed. Note that, as shown in FIG. 1, the position where the leading end of the wire rod supply device 7 is below the winding roll 5 and winds the veneer veneer is hereinafter referred to as a "winding position".

FIG. 2 is a schematic side view showing a state where the wire feeder 7 is waiting at a predetermined position prior to winding the veneer veneer onto the winding roll 5. Less than,
This position is called a “standby position”. The "standby position" is a state in which the position of the wire feeder 7 is above the take-up roll 5 in the transport direction of the veneer veneer, as is apparent from the drawing. For this reason, of the veneer veneers cut by the veneer lace in the previous process, veneer veneers that do not need to be wound on the take-up roll 5 pass directly below the take-up roll 5 and are conveyed to the next process. It can be conveyed by the belt 11a. In such a case, it is desirable that the take-up roll 5 is separated from the veneer veneer conveyance path by an elevating device (not shown).

As is clear from FIGS. 1 and 2, when the wire feeder 7 is moved from the "winding position" to the "standby position", the wire feeder 7 is temporarily moved to the veneer veneer by the horizontal cylinder 71a. After moving to the lower side in the transport direction, the moving is performed by moving the lifting cylinder 71b upward.

Next, FIG. 3 is a schematic side view for explaining the configuration and operation of the moving device 71. In the figure, a wire feeder mounting base 70 is mounted on a horizontal bearing 71e provided with a bearing case for linear motion, and the horizontal bearing 71e moves on a horizontal orbit shaft 71c provided on a mounting base 71g to move the horizontal cylinder 71a. It can move back and forth by actuation.

Next, the mounting base 71g is mounted on an elevating bearing 71f provided with a bearing case for linear motion, and the elevating bearing 71f moves on an elevating orbit shaft 71d provided on the machine frame 21 to operate the elevating cylinder 71b. Can move up and down. As described above, the wire supply device 7 can be moved by the moving device 71 between the “standby position” and the “winding position”.

FIGS. 4 and 5 are views for explaining the mounting relationship between the wire feeding device 7 and the wire feeding device mounting base 70 and the positional relationship between the wire feeding device 7 and the touch roll 11b at the "winding position". It is. As shown in FIG. 4, the wire feeders 7 are provided at a plurality of locations at appropriate intervals in the rotation axis direction of the touch roll 11b. For example, when the veneer veneer has a pulling width of 8 feet (about 2.4 m), about 4 to 7 locations are provided at appropriate intervals in the axial direction. That is, since the number of installation points of the wire feeder depends on how many wires are wound with the veneer veneer, in the case of the veneer veneer which is easy to wind up, the number of wires 3 to be used is small. Good. By the way, if the thickness of veneer veneer is 1 mm or less and there are few cracks, four places may be used.
When the plate thickness is large or when a veneer veneer with many cracks is to be wound, it is preferable to provide seven or more veneer plates. Thus, according to the properties of the veneer veneer to be wound,
It is desirable to set the installation location of the wire feeder in advance.

In the drawing, reference numeral 7a denotes a wire feed nozzle.
At the "winding position", the wire supply nozzle 7a is housed in a groove provided in advance on the touch roll 11b. The wire 3 is wound up together with the veneer veneer conveyed by the conveyor belt 11a while being sequentially discharged from the leading end opening of the wire supply nozzle. Also, in FIG. 5, it can be seen that, similarly to the wire supply nozzle, the transport belt 11a is housed in the groove provided on the touch roll 11b together with the belt support table 11c that holds the transport belt 11a.

Next, a detailed description will be given with reference to FIGS. FIG. 6 shows the “standby position” of the wire rod supply device 7 as described above. First, the wire 3 will be described. The wire 3 serves as a guide for successively winding the conveyed veneer veneer around the take-up roll 5 and winding the veneer veneer onto the wound veneer veneer in a state where the subsequent veneer veneer is loose. The wire 3 is used for winding a veneer veneer with a certain tension applied to the wire 3 so that the wire 3 is not bent or wound due to an increase in looseness at the time of winding. If the veneer veneer is wound up in a bent state, cracks may occur in the bent and overlapped portions, resulting in poor quality or wound balls wound in a later process. When performing the rewinding work, there is a problem that the yield is reduced due to cracking.

The wire used to achieve the above purpose is required to be thin, have a relatively high tensile strength, and have a long length per one turn from the viewpoint of workability. Was. In order to meet these requirements, a polyester yarn is used in the embodiment of the present invention. As for the thickness of the polyester yarn used,
Depending on the thickness of the veneer veneer to be wound, it is used as appropriate.
By the way, when the veneer veneer is thin, a polyester yarn with a thickness of 500 denier is used.
Change to 2,000 denier polyester yarn for use. By the way, denier is "a unit that expresses the thickness of fibers and yarns, and the weight per 9000 m in length expressed in grams".

The wire 3 is connected to a wire tension device 30 (hereinafter, referred to as a wire tension device 30).
The tension is adjusted so that a predetermined tension is applied by passing through a tension device. That is, the tension device 30 includes a ceramic pressure gate 30a and a fixed gate 30b.
(Shown by oblique lines in the figure), and tension is applied to the wire 3 by utilizing the frictional force generated when the wire 3 moves while being wound around these gates. . For this reason, the pressure gate 30a is provided so as to close to the fixed gate 30b using an elastic member (not shown) such as a pressing cylinder or a spring or a gravity member (not shown) such as a weight. Thus, the wire 3 is sandwiched between the respective gates.

The magnitude of the tension acting on the wire 3 increases as the wire 3 is more sandwiched between the pressure gate 30a and the fixed gate 30b, that is, as the winding angle with respect to the gate increases. Increasing the pressing force 30a increases the amount of pinching between the wire 3 and the gate, so that the tension acting on the wire 3 also increases. In the tension device 30, the tension is kept constant by pressing the pressure gate 30a with a spring (not shown).

In the embodiment of the present invention, the wire 3
Is adjusted to about 500 g. As for the magnitude of this tension, it is desirable to obtain an appropriate value by performing adjustment while actually winding the veneer veneer.
The breaking strength of a 500 denier yarn is about 2.5 kg.

Next, the wire feeder 7 is urged by the pressurizing spring 7b and receives a clockwise operation around the pivot 7c. Since the upper limit of the rotation is regulated by the stopper 7d, the wire feeder main body 7g is normally in a state of contact with the stopper 7d as shown in the drawing. The reason why the wire rod supply device body is urged by the pressurizing spring 7d will be described later in detail, but this is so that the wound ball 4 that has been wound up by the wire rod supply nozzle 7a can be pressed and held with a constant force.

FIGS. 7 to 9 are schematic side views for explaining a preparatory step for winding a veneer veneer. FIG.
FIG. 4 is a schematic side view for explaining a state in which a wire 3 is discharged from a wire feeder 7 and is wound around a winding roll 5.
First, a wire rod hole 7 provided in a wire feeder body 7g is provided.
The wire 3 is prepared in advance by inserting the wire 3 into k. However, this work should be performed first, and thereafter, is unnecessary work except when the wire is cut or replaced with another new wire.

The wire feeder body 7g is provided with a fluid supply hose 7e (hereinafter simply referred to as a fluid hose), and the fluid supplied through the fluid hose passes through the wire hole 7k to supply the wire. It is discharged from the nozzle 7a. Compressed air is used as a fluid to be supplied to the fluid hose 7e. Therefore, when the compressed air passes through the wire hole, the inserted wire 3 can be wound into the compressed air and the wire 3 can be discharged from the tip of the wire supply nozzle 7a together with the compressed air.

By the way, such a method of supplying a wire together with a fluid has been conventionally performed. However, the conventional method of simply supplying the fluid cannot make the discharge amount of the wire constant, and particularly, When the discharge amount is insufficient, there is a problem that the veneer veneer cannot be wound. Therefore, in the present invention, when the wire is discharged together with the fluid from the wire supply nozzle 7a, the discharge supply amount of the wire is controlled by the capstan roll 9.

That is, the capstan roll 9 employed in the embodiment of the present invention is configured to rotate by a predetermined amount by being supplied with a driving force from a motor (not shown) provided to be capable of rotating forward and backward. Further, a driven roll 9a is provided facing the capstan roll 9, and the driven roll is configured to be able to be pressed against the capstan roll 9 by a pressing member (not shown). Therefore, the driven roll 9
a is pressed against the capstan roll 9, the capstan roll 9 is driven to rotate by a predetermined amount, and compressed air is supplied from the fluid supply hose 7e, so that a predetermined amount of the wire 3 can be discharged without excess and deficiency. . When the discharge of the wire 3 is completed, the pressing of the driven roll 9a against the capstan roll 9 is released.

If the compressed air is continuously supplied when supplying the compressed air, the wire 3 may swirl inside the wire hole 7k, and as a result, the discharge supply amount of the wire 3 may become unstable. was there. However, it has been found that these problems do not occur by devising the method of supplying the compressed air. That is, by intermittently supplying the compressed air, a predetermined amount of the wire can be reliably discharged without the wire 3 being swirled inside the wire hole 7k.
When the supply of the compressed air is performed intermittently, the capstan roll 9 may be driven to rotate in synchronization with the intermittent supply.

In this manner, the wire 3 discharged from the wire supply nozzle 7a passes above the take-up roll 5 from the lower side in the veneer veneer transport direction of the take-up roll 5 and is directed upward. Is discharged by a predetermined length.
Then, as shown in FIG. 7, by setting the tip of the wire 3 to a position lower than the transport belt 11b,
Next, when a veneer veneer is conveyed, it is laid so as to have a positional relationship that hinders the course of the veneer veneer.

FIG. 8 shows that the wire feeder 7 is
Indicates a state in the middle of moving from the “standby position” to the “winding position”. The wire feeder 7 starts to descend from the “standby position” shown by the dotted line in the figure, and moves to the position shown by the solid line, that is, the wire feed nozzle 7a
Move to a position lower than a. Incidentally, with this movement, a phenomenon occurs in which the wire 3 is pulled back toward the lower side in the veneer veneer conveyance direction. However, in the step of discharging the wire 3, the wire 3 is taken into consideration in consideration of the amount of the wire 3 being pulled back. By discharging a wire having a sufficient length, the leading end of the wire 3 will not be higher than the height of the conveyor belt, so that the wire 3 can hinder the course of the veneer veneer. It is possible to maintain the positional relationship.

FIG. 9 shows a state in which the movement of the wire feeder 7 to the "winding position" is completed. The "winding position" is a position where the wire feeder 7 is further moved from the position in FIG. 8 toward the upper side in the veneer veneer conveying direction, and the leading end portion of the wire feed nozzle 7a is 5, the take-up roll 5
Is in a groove provided in the groove. When the preparation is completed after moving to the final "winding position" in this way, the conveyance of the veneer veneer is started next.

FIGS. 10 to 12 are schematic side views for explaining a state in which a veneer veneer is wound on a take-up roll 5. First, how the veneer veneer 1 is guided to the winding roll 5 by the wire 3 will be described with reference to FIG. When the transport belt 11a starts running, the take-up roll 5 starts rotating in the direction of the arrow due to the frictional force with the transport belt 11a, and at the same time, the rotatably provided touch roll 11b also contacts the take-up roll 5. It starts rotating in the direction of the arrow due to the frictional force.

When the winding roll 5 starts to rotate, a frictional force acts on the wire 5 with the winding roll 5.
There is not enough force to wrap around, and it is usually slipped.

Next, since the wire 3 is in a positional relationship of obstructing the course of the veneer veneer, the leading end of the conveyed veneer veneer 1 is wound around the winding roll 5 as shown in FIG. Then, the wire 5 is engaged with the wire 5 that is waiting in a hanging state, and is further transported while maintaining the engaged state.

FIG. 11 shows a state in which the veneer veneer 1 is wound on the winding roll 5 by the guidance of the wire 3. As shown in the figure, the conveyed veneer veneer 1 is carried in between the take-up roll 5 and the touch roll 11b in a state where the wire 3 is fixed to the front end thereof. Since the wire 3 is supplied in contact with the back side of the veneer veneer, the wire 3 serves as a guide for regulating the transport direction of the veneer veneer. It is guided along the outer diameter of the take-up roll 5 and is taken up sequentially with the rotation of the take-up roll 5.

As a means for more securely winding the conveyed veneer veneer around the take-up roll 5, for example, a wire material such as sanding paper or the like on the outer peripheral surface of the take-up roll 5 is easily entangled. A stop member (not shown) may be provided. That is, since the winding roll 5 starts rotating with the wire entangled with the locking member, the winding rod 3 is already in contact with the conveyed veneer veneer. It is wrapped around. Therefore, the veneer veneer 1 is composed of the winding roll 5 and the wire 3
Between the take-up roll 5
Can be reliably guided along the outer peripheral surface of the reel.

Further, as another means, when the wire 3 is discharged and supplied, a liquid such as water is used instead of the compressed air, and the liquid has an effect of attaching the wire 3 to the winding roll 5. Therefore, the winding roll 5 starts rotating with the wire 3 adhered to the outer peripheral surface in the same manner as when the locking member is used. Accordingly, the veneer veneer 1 is transported between the take-up roll 5 and the wire 3, and thus can be reliably guided along the outer peripheral surface of the take-up roll 5.

FIG. 12 shows a state where the veneer veneer 1 is continuously wound up. The veneer veneer 1 is sequentially wound up with the rotation of the winding roll 5, and gradually becomes a large wound ball 4. Since the wire 3 is in contact with the back surface of the veneer veneer 1 and is given a constant tension, the veneer veneer 1 to be wound is brought into close contact with the already wound veneer veneer 1 and wound up. Thus, a solid ball 4 without looseness can be formed as a whole.

FIG. 13 is a schematic side view for explaining the finished state of the winding of the veneer veneer 1. First, even after the winding of the veneer veneer 1 has been completed, the traveling of the conveyor belt 11a is continued, so that the wire 3 is extraly wound around the outer periphery of the wound ball 4 a plurality of times. By doing so, the wound ball can be firmly fixed, so that the end portion of the wound ball does not loosen and the wound shape does not collapse.

Next, as shown in FIG.
Is stopped, the wire rod supply device 7 is raised from the position shown by the broken line, and the wire rod supply nozzle 7a is brought into contact with the winding ball 4 to be pressed, and the pressed state by the wire rod supply nozzle 7a is maintained. The wound ball 4 is lifted by an elevating device (not shown) while being moved out of the veneer veneer conveyance path. As described above, the wire rod supply device main body 7g is subjected to the clockwise operation in the figure around the rotation fulcrum 7c by the pressing spring 7b. Then, this time, it is pressed downward around the rotation fulcrum 7c, and rotates by the counterclockwise action in the figure. Therefore, at this time, the pressing spring 7b is compressed, so that
Is a wire feed nozzle 7a with a constant force of the pressure spring 7b.
Is pressed and held. Therefore, the wound ball 4 can stand by without rotating without stopping.

When the winding of the veneer veneer 1 has been completed, the wire 3 is cut in order to transport the wound ball 4 to the next rewinding step. The cutting of the wire 3 is performed by energizing and heating a heater 7h (not shown) provided in the wire cutting member 7f, pressing the driven roll 9a following the capstan roll 9, and then rotating the capstan roll 9 reversely. The wire 3 can be easily cut by pulling it.

When the wire 3 is cut, the wound ball 4 is transported to the next step. At this time, the pressing and holding by the wire supply nozzle 7a is released, but since the wire 3 has already been wound around the outer circumference of the wound ball a plurality of times, the wound shape of the wound ball 4 may be broken. And can be transported to the next step.

Since the cut wire 3 remains in the wire hole 7k of the wire feeder main body 7g, it is not necessary to newly insert the wire 3 into the wire hole 7k in preparation for the next winding. Accordingly, as described above, the compressed air can be discharged from the wire supply nozzle 7a only by supplying the compressed air to the fluid supply hose 7e.

By the way, depending on the diameter of the raw wood and the difference in the material, among the veneer veneers to be cut, the amount of veneer veneer suitable for winding may be small. In the case of such a raw wood, the amount wound by the take-up roll 5 is naturally small, and consequently, when the cutting of one raw wood is completed, the roll 4 is transported to the next rewinding step, which means that productivity is low. This is not desirable from the viewpoint of workability.

Therefore, if the wound ball 4 has room for winding the veneer veneer 1 further, the present invention
In preparation for the next log, the wire 3 is not cut off but kept on standby outside the veneer veneer transport path as shown in FIG. For this reason, for example, the veneer veneer veneer that is not suitable for winding, which is first conveyed after cutting the next log, is directly conveyed below the ball 4 by the conveying belt 11a and conveyed to the next step. You can do it. Therefore, as in the prior art, the wound ball is once raised after cutting the wound ball and wire, and then, when a veneer veneer suitable for winding is cut, the wound ball is lowered, and the wire is manually wound again. Work such as dropping and fastening is no longer required.

In the present invention, when the veneer veneer suitable for winding is cut, the cutting of the raw wood is temporarily stopped and the running of the conveyor belt 11a is stopped. Then, the wound ball 4 is lowered onto the conveyor belt 11a, and the wire supply nozzle 7 is further lowered to release the state of pressing and holding the wound ball, and the "winding position" as shown in FIG.

FIG. 14 shows the roll 4 once the winding has been completed.
FIG. 3 is a schematic side view for explaining a state in which a veneer veneer cut from the next log is continuously wound. If the transport of the veneer veneer 1 is started by running the transport belt 11a in this state, winding can be continued. Therefore, the veneer veneer discharged from the next log can be continuously wound up without cutting the wire 3 as in the related art.

As described above, according to the present invention, another new veneer veneer can be continuously wound on a wound ball which has been completely wound as required. It can also be implemented as follows. That is, in the above-described embodiment, the case where one take-up device 2 is provided for the veneer veneer transfer device 11 has been described. However, the present invention is not limited to one place, and a plurality of places may be provided. it can. For example, a case will be described in which two winding devices 2 are provided on the transport belt 11a at appropriate intervals in the veneer veneer transport direction.

Normally, when a single log is cut, the cross section of the log is non-circular because the log is a natural material as described above. The veneer is cut and subsequently a continuous veneer veneer is cut. If the quality of the raw wood is poor, even if continuous veneer veneer is cut, the veneer veneer is cracked or decayed. It may not be able to be peeled off for the middle plate.

Even in the case where veneer veneers having different thicknesses are cut from one log as described above, the provision of the two winding devices 2 allows the take-up roll 5 to take up a thin veneer veneer. If veneer veneer is wound on the other side, veneer veneer cut from a plurality of logs can be continuously wound.

Further, by providing the winding device 2 at a plurality of positions, even if the veneer veneer has the same thickness, it can be wound up by the winding rolls at a plurality of positions. Since it can be taken up by another take-up roll while it is conveyed to the next process and a new take-up roll 5 is being prepared, there is no loss time, and workability is further improved. In this way, by arranging the winding device 2 at a plurality of positions, winding according to the purpose can be efficiently performed.

Since the present invention is constructed as described above, it has the following effects. First, according to the first and fourth aspects of the present invention, prior to winding of the veneer veneer, the wire rod is moved from a position above the take-up roll upward in the veneer veneer transport direction of the take-up roll. Discharges and supplies the wire together with the fluid from the wire rod supply device so as to block the transport path of the veneer veneer to be transported, and then keeps the discharged and supplied wire obstructing the transport path of the veneer veneer. The wire feeder is moved from the lower side of the take-up roll in the veneer veneer transport direction to below the take-up roll, and then the veneer veneer is transported and the veneer veneer is moved together with the wire. Conventionally, winding is performed by manually fastening the wire to the winding roll or by providing a locking member for locking the wire to the winding roll. However, the present invention Since it is possible to automatically wind the veneer with wire according, labor saving and productivity is greatly improved. Further, a conventional winding roll can be used as it is.

Next, according to the second and fifth aspects of the present invention, when the wire is discharged and supplied from the wire supply device together with the fluid, the discharge and supply amount of the wire is controlled by the capstan roller. Since the supply is performed, the wire rod having a predetermined length can be discharged without excess and deficiency.

Next, according to the third aspect of the present invention, the take-up roll, which has finished taking up the veneer veneer, is connected to the outer peripheral surface of the veneer veneer taken up by the take-up roll by the wire feeder. While being pressed and held, the veneer veneer is moved from the transport path of the veneer veneer to be once separated, and then the winding roll is moved again on the veneer veneer transport path, and then the veneer veneer is moved by the wire feeder. Release the pressure hold on the outer peripheral surface,
Next, since the subsequent veneer veneer is conveyed and wound up together with the wire, even if the winding of the veneer veneer is interrupted once, the subsequent new veneer veneer is continuously taken up. Since the plate can be automatically wound, labor saving and productivity have been greatly improved.
