Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a veneer veneer winding device.

Conventionally, in plywood factories, veneer veneer (veneer veneer in the present invention includes not only a single veneer veneer but also a so-called veneer veneer group consisting of a plurality of veneer veneers) In order to change the conveyance direction of the veneer (hereinafter simply referred to as veneer) in a direction perpendicular to the fibers, a conveyor etc. that changes the conveyance direction within a small angle where the elasticity of the veneer can be utilized is used. Since there is only a means for connecting the conveying mechanisms, various problems arise when attempting to rationalize the processing process by connecting various mechanical devices that convey veneers in different directions, for example.

That is, for example, a roll dryer that dries the veneer while conveying it in the same direction as the fibers, and a veneer cross-setting machine that performs the cross-setting while conveying the veneer in a direction perpendicular to the fibers are connected together. When trying to rationalize the process, for example, as illustrated in FIG. 1, a veneer flattening machine E is arranged at right angles to a roll dryer D, and the fibers are carried out from the roll dryer D in the same direction as the fibers. After the veneer T is once received by a delivery conveyor U, for example, a delivery conveyor U consisting of a feed roll 1, a ruler 2, a conveyor belt 3 etc. disposed retractably between the feed rolls, etc. Since the fibers must be connected to the veneer cross-cutting machine E in a direction perpendicular to the fibers by means of a connecting conveyor L, etc., the stacking device F of the veneer cross-crossing machine E is
The required space in the direction perpendicular to Dryer D including In cases where processing is to be carried out using the veneer flattening machine E, it is practically impossible to connect the conveyor L due to the length of the connecting conveyor L.

The present invention provides a veneer winding device that can arbitrarily change the conveyance direction of the veneer in a very narrow space by utilizing the characteristics of the veneer that is extremely flexible in the direction perpendicular to the fibers. By doing this, it is easy to connect various mechanical devices in a plywood factory,
This is intended to streamline the veneer processing process in plywood factories, and the processing equipment is, for example, the second
As illustrated in the figure, there is a relay position between the first conveyance mechanism and the second conveyance mechanism, which convey the veneer T in different directions orthogonal to the fibers, for example, the first conveyor L1 or the like consisting of the conveyor belt ₅ , etc. It is placed at a relay position between the conveyance mechanism and a second conveyance mechanism such as a connected conveyor L ₂ consisting of a conveyor belt 6 etc. to change the conveyance direction of the veneer T.The basic principle is that the winding shaft Single plate payout mechanism A consisting of wire guide members, etc.
The veneer T is once rolled up by the veneer T, and then the conveying direction is changed by rotating the veneer delivery mechanism A and then winding it up.
Furthermore, based on the basic principle, a plurality of the veneer dispensing mechanisms A are provided, and the plurality of veneer dispensing mechanisms A are rotated in order, so that the veneer transport direction can be changed more efficiently. DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a veneer winding apparatus according to the first aspect of the present invention will be described in detail based on the embodiments illustrated in FIGS. 3 to 11.

In FIGS. 3 and 4, 7 is a winding shaft, which is fitted with sliding bearings 12 at both ends, inserted into a groove 13a of a lift stand 13, and pivoted to the lift stand 13. Both the drive shaft 15 and the motor
It is placed on a drive pulley 14 that can be rotated in forward and reverse directions by a suitable drive device (not shown) such as a clutch or brake. Reference numeral 8 denotes a belt having an appropriate length, and the starting end of the belt is permanently fixed at an appropriate position on the winding shaft 7 by appropriate means such as gluing or riveting as necessary. 10 is a belt guide arm that guides the belt 8 to an appropriate position on the winding shaft 7,
The proximal end is fixed to the lift stand 13 so as to be substantially integral with the winding shaft 7, and a guide ring 9 is attached to the distal end as shown in the figure, if necessary. Reference numeral 11 denotes a belt case with a built-in spiral spring for storing the belt 8, and is attached to the belt guide arm 8, for example, as shown in the figure. Reference numeral 18 denotes a support base that supports the veneer payout mechanism A made up of the above-mentioned members, and supports the veneer payout mechanism A in a rotatable manner via a fulcrum pin 16 and a pivot bearing 17. Reference numeral 19 denotes a turning mechanism such as a rotary cylinder or a worm gear for turning the single plate payout mechanism A.

For example, according to a processing device having the above-mentioned configuration, as is clear from _FIG.
The veneer T was transported in the direction perpendicular to the fibers by
is guided to the outer periphery of the winding shaft 7 by the belt 8, and is once rolled up together with the belt 8, and then the veneer dispensing mechanism A that has finished the winding process is connected to the connecting conveyor _L2. After turning the veneer T on the connecting conveyor _L2 as shown in Fig. 6,
By unwinding the fibers, the direction of conveyance of the veneer T, which is conveyed in a direction perpendicular to the fibers, can be changed.

The veneer is a material with remarkable anisotropy, and while it is strong in the same direction as the fibers, it is extremely flexible in the direction perpendicular to the fibers, so it is easy to wind up. Utilizing this characteristic, as mentioned above, the veneer is wound in a direction perpendicular to the fibers to change the conveying direction, so even if the veneer is a long veneer, such as the one being carried out from a roll dryer, However, the conveyance direction can be changed arbitrarily in an extremely narrow space, making it easy to connect various mechanical devices in plywood factories, which was previously considered difficult due to differences in conveyance direction. Since the board is wound and unwound together with the wire rod, it is possible to do this without disturbing the arrangement of the veneers (so-called veneer group), as shown in the figure, even if the veneer has gaps here and there, for example. Combined with the ability to perform extremely orderly direction changes, it is possible to dramatically streamline the veneer processing process.

In the embodiment illustrated in FIGS. 7 to 9, 2

Note that a drive device such as a DC motor connected to the winding shaft 7 to drive the winding shaft 7 is not shown for convenience.

In this embodiment, as in the previous embodiment, the veneer T, which has been conveyed in the direction perpendicular to the fibers by the connecting conveyor _L1 , is guided to the outer periphery of the winding shaft 7 by the belt 8. 8, the veneer T is wound up once, and then the veneer delivery mechanism A that has finished the winding process is turned in a direction to be connected to the connecting conveyor L ₂ , and then the veneer T is rewound onto the connecting conveyor L ₂ . By processing, the conveying direction of the veneer T, which is conveyed in a direction perpendicular to the fibers, can be changed to an arbitrary direction.

In the embodiment illustrated in FIGS. 10 and 11, 29 is the drive shaft 14 and drive pulley 1.
5. A yarn guide arm that also serves as a support for an auxiliary conveyor consisting of a guide pulley 35, a guide belt 36, etc., and includes a swing metal 32 and a fulcrum pin 33.
A bobbin 3 with a built-in spiral spring has a proximal end fixed to a rotating base 34 which swingably holds the winding shaft 7 through the spool 3, and houses a thread 30 having an appropriate length.
1 will be attached. Reference numeral 37 denotes a column that rotatably supports the veneer storage mechanism A made up of the above-mentioned members.

In this embodiment, as in the previous embodiment, the veneer transport direction can be controlled in an extremely narrow space by winding, turning, and unwinding the veneer T by the veneer delivery mechanism A. It can be easily converted to any direction.

As is clear from the above embodiments, the veneer pay-out mechanism is not limited to a specific form, and is essentially arranged to be rotatable in the forward and reverse directions in order to wind up and unwind the veneer together with the wire. A wire guide member for guiding the wire unreeled from the wire storage member to an appropriate position on the winding shaft is substantially integrally attached to the winding shaft provided so that the veneer is guided by the wire to the winding shaft. It is sufficient that the structure is such that it can be wound together with the wire while being guided around the outer periphery of the wire, and can be unwound after turning, and most of the members in each of the above embodiments can be replaced with each other. Of course, various modifications are possible in addition to the embodiments exemplified in the above embodiments, and modifications of each member and application examples of the apparatus will be described in further detail below.

First, we will discuss how to make the winding shaft, which winds and unwinds the veneer together with the wire rod, freely rotate forward and backward.
As illustrated in the embodiment illustrated in FIGS. 4 and 4 (hereinafter referred to as the first embodiment) or the embodiment illustrated in FIGS. 10 and 11 (hereinafter referred to as the third embodiment) means indirectly driven by a drive pulley or an auxiliary conveyor that can be rotated in forward and reverse directions, or an appropriate means such as the embodiment illustrated in FIGS. 7 to 9 (hereinafter referred to as the second embodiment). means for driving directly by a drive device;
Furthermore, there are various methods such as a method for rotating the wire rod by collecting the wire only during unwinding.
In any case, the speed at the time of winding and the speed at the time of rewinding do not necessarily have to be the same speed, and of course they may be either continuous drive or intermittent drive corresponding to the drive of each transport mechanism. In addition, when directly driving the winding shaft, the diameter of the winding shaft is large for processing relatively short or thin veneers, and the diameter of the winding shaft is large for processing relatively short or thin veneers. It is desirable to take measures such as changing the number of rotations of the winding shaft so that changes in the outer circumferential speed caused by changes in the outer diameter of the rolled ball during winding and unwinding do not adversely affect the processing.

Next, there is no specific shape for the wire guide member that guides the wire to an appropriate position on the winding shaft, and in short, it is attached substantially integrally to the winding shaft, as in each arm illustrated in each embodiment. , any shape may be used as long as it is configured to guide the wire drawn out from the wire storage member to an appropriate position on the winding shaft, and although not shown in the drawings, a guide ring or a It is also possible to add thread guide holes, thread guide holes, etc. to guide the wire three-dimensionally. Furthermore, it would be convenient if the wire guide position could be changed.

Next, since the wire rod is to be wound and unwound together with the veneer, the first and second embodiments
It is preferable to use a flexible material such as a belt as exemplified in the embodiment or a thread as exemplified in the third embodiment, but the width, thickness, or thickness thereof is not necessarily narrow, extremely thin, or extremely fine. Although it is not necessary and not shown in the drawings, for example, even if the belt is relatively thick, if the winding shaft is indirectly driven, the belt can be driven via the belt. Even if the belt has a width that is less than the full width of the veneer, there is no problem in practical use because it can completely prevent partial deformation of the outer diameter of the wound ball due to the presence or absence of the belt. However, from the point of view of miniaturization and simplicity of the device, narrow and thin belts or fine threads are most convenient, and various belts and tapes made of synthetic resin, cloth, metal, leather, etc., or natural fibers are most convenient. - Various types of strong and flexible wire materials can be used as wire materials in the present invention, such as various threads and strings made of synthetic fibers, and even filament-like wire materials such as thin gold wires. In addition, the number of wire rods (number of threads) can be selected appropriately depending on the conditions such as the width of the veneer or the width (thickness) of the wire rod. It is also possible to selectively feed out only arbitrary wire rods to appropriate positions corresponding to changes in veneer width, etc., without changing the attachment position. In addition, when collecting the wire rod in a wire storage member for repeated use, it is most convenient to permanently lock the starting end of the wire rod to the winding shaft by appropriate means such as gluing, riveting, or tightening.
If you want to collect and dispose of the wire separately, or if you want to use it as is to reinforce or join the veneer together with adhesive, it is most convenient to wrap the starting end of the wire around the winding shaft several times. .

Next, regarding the wire storage member, there are commercially available belt cases with built-in spiral springs as exemplified in the first and second embodiments, or pegs with built-in spiral springs as exemplified in the third embodiment. A tape measure with a built-in spring (convex rule) or a well-known car seat belt case with a built-in wire collection function is convenient for collecting wire and reusing it repeatedly, but for example, for fishing. It is equally convenient to have a wire collection function attached to or externally connected to the winding drum for storing the wire, such as the electric reel and the combination of the winding shaft and drive pulley of the present invention. It is convenient to attach a spiral spring to a fixed winding drum and use the spiral spring as a wire. However, although not shown in the drawings, for example, the drive pulley may press the wire with a rotatable idler wheel on a winding shaft that is directly driven, or the wire may be pressed with a drive wheel on a guide wheel. When the wire rod is made to run directly and the wire rod is allowed to hang down, and the wire rod is collected using its own weight, for example, a box-shaped
A simple container with an open top, such as a cylinder or a bottle, can be used.For example, if the wire material is an inexpensive wire material like thread, it can be cut after each winding process, and a collection mechanism and disposal mechanism provided separately. When winding the veneer, the wire is collected and disposed of as is, or when winding the veneer, adhesive is used in combination by impregnating, covering, or applying adhesive to one or both sides of the wire. When the wire is bonded to the veneer and used for reinforcing or joining the veneer, the wire is simply stored (stored). There is no problem with a winding drum such as a bobbin, but in any case, when winding veneer, it is desirable to apply appropriate tension to the wire, and if necessary, use a torque limiter or one-way clutch. It is effective to attach a braking mechanism such as the above to the winding drum, idler wheel, guide wheel, etc. Furthermore, in each of the embodiments, the wire rod storage member is attached to the wire rod guide member so as to rotate together with the wire rod guide member, but the shape of the wire rod guide member may be appropriately set, for example by adding a guide ring. If care is taken to prevent the wire from derailing when turning, there is no problem even if the wire storage member is not attached to the wire guide member.
For example, it may be fixedly attached to a support member or fixed on the ground.

Next, the support member for supporting the veneer retracting mechanism consisting of the winding shaft and the wire guide member is not limited to a specific form, and in short, any member can support the veneer retracting mechanism in a pivotable manner. Any form is acceptable. In addition, when rotating the veneer pay-out mechanism, it is possible to rotate it manually, but it is easier to forcefully rotate it by attaching a rotating mechanism as exemplified in the first embodiment. Although omitted, the startup and
Winding is performed based on a stop signal, a veneer passing signal emitted from a veneer detector consisting of a limit switch attached to each conveyance mechanism, etc., or a transmitter consisting of a transducer attached to the winding shaft, etc. It would be even more effective to include a control device that starts and stops the drive of the take-up shaft and controls the operation of the turning mechanism, so that the turning mechanism is automatically turned for each process. In addition, examples of the rotating mechanism include a rotary cylinder, worm gear,
Any conventionally known turning mechanism for turning an object, such as a cam or a motor with a speed reducer, etc., can be used.

In each of the embodiments, the veneer dispensing mechanism is configured to rotate in the horizontal direction, but it may also be configured to rotate in the vertical direction or a combination of both directions, and the rotation angle can be set arbitrarily. Needless to say, the turning form is not limited to the reciprocating turning as in each embodiment, but may be turning in one direction. Furthermore, if the turning angle is changed stepwise each time, other second conveyance mechanisms, that is, so-called third and fourth conveyance mechanisms whose veneer conveyance direction is different from the second conveyance mechanism, can be used. Since it is possible to rewind veneers into the mechanism, it is also possible to change the conveyance direction of veneers brought in from one direction to multiple directions, and if used conversely, it is possible to rewind veneers brought in from multiple directions. It is also possible to change the conveyance direction of the plate to one direction. In addition, in each embodiment, a head was provided between each transport mechanism and the veneer retracting mechanism, and each transport mechanism and the veneer retractor mechanism were rotated by taking turns due to the head difference. If the whole or part of the conveyance mechanism or the wire guide member of the veneer storage mechanism can be moved up and down or back and forth to prevent it from falling when connected, it will prevent the veneer arrangement from being disturbed and the veneer This is effective in terms of preventing damage. Furthermore, if necessary, a clipper may be provided on the first conveyance mechanism side so that the veneers can be cut, and extremely long veneers may be cut into appropriate lengths and processed separately.

The veneer winding device according to the second aspect of the present invention includes a plurality of veneer winding devices having the same configuration as the veneer retracting mechanism described in the veneer winding device according to the first invention. Each unit is provided with a plate dispensing mechanism rotatably supported by a support member, a rotating mechanism for rotating the plurality of veneer dispensing mechanisms, and a control device for controlling the operation of the rotating mechanism. The plate dispensing mechanism is connected to the first conveying mechanism and the second conveying mechanism in order, so that the conveying direction of the veneer can be changed more efficiently.
A detailed description will be given based on the embodiments illustrated in FIGS. 2 to 15.

In Fig. 12 and Fig. 13, A ₁ and A ₂ are single plate retracting mechanisms, and a suitable drive device (not shown) is used.
The belt guide arm 10 is substantially integrally attached to the winding shaft 7 which is directly driven by the winding shaft 7 via the bearing box 21 and the pivot base 34, Each is rotatably supported. Reference numerals 19a and 19b are turning mechanisms, which are attached to the support column 37 so as to turn the veneer storage mechanisms _A1 and _A2, respectively. 3
Reference numeral 8 denotes a transmitter, which is composed of, for example, a transducer attached to the winding shaft 7, and emits a veneer passing signal to a control device 39, which will be described later. 39 sequentially controls each of the veneer retracting mechanisms A ₁ and A ₂ based on the veneer passage signal etc. emitted from the transmitter 38.
This is a control device that controls the operation of the turning mechanisms 19a and 19b so as to be connected to the transport mechanism and the second transport mechanism.

For example, according to the processing device configured as described above, the veneers T transported in the direction orthogonal to the fibers by the first transport mechanism comprising a connecting conveyor (not shown) or the like are first transferred to one of the veneers T. The belt 8 of the upper veneer storage mechanism _A1 is guided to the outer periphery of the winding shaft 7, and the belt 8 and the belt 8 are once wound onto the winding shaft 7, and then the transmitter 38 By the operation of the turning mechanism 19a under the control of the control device 39 based on the veneer passing signal emitted from the veneer passage signal, the veneer is rotated while being stored in the veneer delivery mechanism _A1 , and then removed from the connecting conveyor (not shown) or the like. However, due to the operation of the turning mechanism 19b under the control of the control device 39, the lower veneer retracting mechanism _A2 is replaced with the first one. Since the veneer T is connected to the conveyance mechanism, other veneers T following the veneer T are sequentially wound up by the lower veneer unloading mechanism _A2 , and thereafter are conveyed by repeating the same operation. The incoming veneers are alternately wound up and unwound by both veneer delivery mechanisms A ₁ and A ₂ , and their conveyance direction is sequentially changed.

Since the veneer winding device according to the first invention has only one veneer dispensing mechanism, the veneer once wound up by the veneer dispensing mechanism is Only after unwinding could the next veneer be rotated again and the next veneer could be wound up, so the conveyance direction of the veneer could only be changed intermittently, so production was limited. However, in the veneer winding device according to the second invention, the veneer can be processed in sequence using a plurality of veneer pay-out mechanisms as described above. It is possible to change the conveying direction of the veneer almost continuously, so to speak, and the effect of being able to change the conveying direction of the veneer in an extremely complete manner with no loss time is extremely significant in practical use when connecting various mechanical devices. It is.

The embodiment illustrated in FIGS. 14 and 15 uses almost all of the members in the second embodiment, and the belt 8 fed out from the belt case 11 is wound around the winding shaft 7 as appropriate. One end of the belt guide arm 20 that guides the belt to the position is connected to the winding shaft 7.
The sliding rollers 23 are fixed to the bearing box 21 of the
A guide metal 2 is attached and pivotally connected to the winding shaft 7.
2, and the belt guide arm 20 is substantially integrally attached to the winding shaft 7. One end is attached to an appropriate number of rail stands 28. The other end is fixed at appropriate intervals on a rotary disk 44 which also serves as a fulcrum pin and which is rotatably supported by a support base 18 via a bearing 17 for rotation. A swing mechanism 19 is attached to the support base 18 and connected to the rotary disk 44, and the operation is controlled by a control device 39.
A drive device 41 consisting of a DC motor or the like that drives the winding shaft 7 via a transmission member such as No. 3 is disposed on the rotary disk 44.

In this embodiment as well, the veneer T conveyed by the connecting conveyor _L1 in the direction perpendicular to the fibers is first wound up by one of the veneer delivery mechanisms A, and then the control device 39 By the operation of the turning mechanism 19 under the control of , the veneer is rotated in the state stored in the veneer storage mechanism A, and then the veneer is sequentially rewound and its conveyance direction is changed. Accordingly, another veneer dispensing mechanism A is replaced and connected to the connecting conveyor _L1 , so the next veneer T, which will be described later, is sequentially wound up by the other veneer dispensing mechanism A. By repeating the same operation after being processed, the conveying direction of the conveyed veneers is changed one after another almost without interruption.

As is clear from both of the above embodiments, the veneer payout mechanism in the veneer winding device according to the second invention is the same as that in the veneer winding device according to the first invention. It has the same configuration as the veneer dispensing mechanism described in detail, and as mentioned above, both can be replaced with each other, but multiple veneer dispensing mechanisms do not necessarily have to have the same form. If the mechanism or the wire guide member of each veneer dispensing mechanism is provided so as to be able to move vertically or reciprocally back and forth, it is possible to combine veneer dispensing mechanisms of different configurations, provided that there is no problem in connection with each transport mechanism. There is no harm in using it.

Furthermore, when connecting a plurality of veneer dispensing mechanisms to the first conveyance mechanism and the second conveyance mechanism in sequence, it is not necessary to rotate each veneer dispensing mechanism in an interlocking manner so that each veneer dispensing mechanism is alternately moved to a predetermined connection position. There is no need to connect them; instead, it is necessary to attach a turning mechanism to each veneer storage mechanism and, for example, make the unwinding process faster than the winding process speed, or
As in the embodiment shown in FIG. 5, a spare veneer retracting mechanism is provided, and the control device is configured to allow the veneer retracting mechanism that has completed the winding or rewinding process to be rotated in advance to near a predetermined connection position. Therefore, by controlling the operation of the rotating mechanism, processing can be performed without interruption, which is more efficient, and when at least one of the transport mechanisms is driven intermittently, the This is effective because short-term discrepancies in veneer transport speed can be easily absorbed.

In the embodiments illustrated in FIGS. 14 and 15, the signal source that emits a signal to the control device is not illustrated, but the signal to the control device is illustrated in FIGS. 12 and 13. As in the embodiment, the signal is not limited to a signal from a transmitter such as a transducer that indirectly detects the passage of the veneer, but for example, the presence or absence of a winding ball (outer diameter) on the outer periphery of the winding shaft can be detected. A limit switch attached to a single plate dispensing mechanism, etc.
A signal from a spool detector consisting of a phototube switch, etc. may be used, or the arrival and passage of the veneer may be directly detected to activate the veneer unloading mechanism and winding shaft.
In order to stop the veneer, signals from veneer detectors consisting of limit switches, phototube switches, etc. installed at the end of the first conveyance mechanism, the beginning of the second conveyance mechanism, the tip of the wire guide member of the veneer delivery mechanism, etc. are shared. If there is no problem, or in addition, if the connected upper and lower mechanical devices emit signals to start and stop the winding shafts of each conveying mechanism and veneer unloading mechanism, these signals may be shared. In short, if it is a signal that directly or indirectly detects the end of the winding and rewinding process, or a signal that can be predicted, it can be used as a signal to the control device, but in any case. However, it is desirable to take into consideration that the control device does not accumulate errors.
It is also desirable to be able to adapt to changes in the length of the veneer to be processed.

As is clear from the above, according to the veneer winding device of the present invention, the conveying direction of the veneer can be easily changed in an extremely narrow space, and if necessary, multiple units can be combined. By using it, it is possible to connect various mechanical devices placed in various positions or directions in the factory, and it greatly contributes to the automation and rationalization of the veneer processing process in plywood factories. , In addition, for example, the present applicant's application, ``Method for side-splitting plywood veneer by winding''
(Japanese Patent Publication No. 55-10379) or "Method for winding veneer veneer" (Japanese Unexamined Patent Publication No. 55-164105), etc., it is used as a winding device for joining and reinforcing veneers, and is used for transportation. It is possible to simultaneously change the direction and join/reinforce the veneers, and it can also be used as a device for carrying out a new method for joining/reinforcing veneers as described below.

That is, when winding up veneers for temporary storage in conventional plywood factories, the adhesive is rolled up together with the veneer to bond the adhesive to the veneer, Reinforcing the veneer is a common practice, but the adhesive is a paper tape with adhesive applied only to one side of the veneer so that it can be bonded only to the desired side of the veneer, and it is extremely soft. Moreover, it was expensive and extremely unsatisfactory in terms of reinforcing strength and cost.

Therefore, for example, as illustrated in FIGS. 16 to 23, two wire rods Y ₁ and Y ₂ , at least one of which can be bonded to the veneer T (in the figure, the solid line indicates
(Only Y ₂ can be bonded) is wound together with the veneer T, and then the veneer T and the wire Y ₁ are bonded from the wound ball.
When unwinding Y ₂ , as illustrated in FIGS. 24 to 31, at the part where the veneer T separates from the rolled ball, one of the wire rods is placed on the veneer side and the other wire rod is placed on the veneer side. By performing the unwinding process while the wire is located on the winding ball side, both wires interfere with each other in such a way as to pull the other wire away from the veneer and the winding ball, so that both can be bonded. Not only continuous veneers without cracks, including wire rods, but also continuous veneers with cracks,
Experiments have shown that even with veneers that have gaps here and there (a so-called veneer group made up of multiple veneers), it is possible to bond extremely reliably bondable wire to the desired side of the veneer. It was confirmed that by carrying out such an unwinding process, it is possible to make a strong and inexpensive bondable wire material made by coating and impregnating the thread with an adhesive.
It can be used in place of conventional paper tape to effectively reinforce and join veneers, and it can also be used as a non-adhesive wire material (in the figure Regarding Y ₁ ) illustrated by the dotted line, as is clear from FIGS. 24 to 31,
It was found that after unwinding the veneer in the opposite position to the bonding wire at the part where it separates from the rolled ball, it can be collected in either direction. Regardless of whether the wire rod is used for adhesive or non-adhesive purposes, the wire rod located on the outer circumferential surface of the rolled ball during winding can be cut at each winding process as necessary. The wire rod of such a veneer winding processing device can be used as is.

Of course, the reason why the number of wire rods is set to two in the above explanation is for the convenience of explaining the principle that the wire rods interfere with each other in the part where the veneer separates from the wound ball, and do not separate the other wire rods. After a single bondable and divisible wire rod is wound together with a veneer, the wire is divided into two parts and unwound with one portion positioned on the veneer side and the other on the winding roll side. There is no harm in doing this,
In addition, the effect of mutual interference between two wires separating each other is greatest when they are adjacent to each other, and decreases when the veneer thickness is shifted by approximately 35 times. It is desirable to increase the number as appropriate depending on the conditions.

As is clear from the above, the present invention provides a veneer winding device that can significantly streamline and automate the veneer processing process in plywood factories compared to conventional methods, and will greatly contribute to the development of the plywood industry. It is something to do.
