Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical ball in which veneer veneers dried by a veneer dryer are assembled and wound on a large-diameter take-up reel, and a mechanical veneer winding device for winding a mechanical veneer. It is about.

[0002]

2. Description of the Related Art Conventionally, veneer veneers cut by veneer lace are usually wound once, stored once as reels on a reeling deck, transferred to a rewind position, and rewinded. While it is or as it is, it is inserted into a veneer dryer in a continuous state and dried with a target moisture content of approximately 8 to 12%. When the veneer veneer dried by the veneer dryer is a continuous veneer, the veneer is cut by a cutting machine so that the ratio of the length in the direction crossing the fiber and the length in the fiber direction becomes approximately 1: 2. It is cut to a fixed length almost in parallel. The veneer veneer cut to the fixed size is usually employed as a top plate or a back plate of plywood. On the other hand, the middle plate constituting the plywood has a thickness approximately twice that of the front plate or the back plate, and the ratio of the length in the direction intersecting with the fiber and the length in the fiber direction is approximately 2: 1. To be cut off.

[0003] These cut veneer veneers are deposited separately for each type of top plate, middle plate and back plate constituting the plywood, and are cured as a plurality of piles in a plywood factory for a certain period of time. Will be done. That is, a veneer veneer is obtained by cutting a log, but even a single log has different properties, moisture content, etc. from the surface layer to the deep layer. In addition, even if the same type of raw wood is used, and even if the wood type is different, the water content will vary widely.

Accordingly, the veneer veneer after drying is a top plate, a middle plate, a back plate constituting a three-layer plywood, or a top plate, a middle plate, a core plate, a middle plate constituting a five-layer plywood, Even in the case of piles that are classified according to the type of the back plate, the finished water content is not constant, and the water content varies. Such a variation in the water content causes poor adhesion in a subsequent pressing step. Also, after commercialization as plywood, if the moisture content of the back plate is higher than that of the front plate, the product itself is warped downward, so-called downward warpage, conversely, the moisture content of the back plate is higher than that of the front plate. If the value is low, the product itself is warped upward, causing so-called upward warpage. In order to eliminate these inconveniences, the variation in the water content is corrected, and at least the water content is equilibrated for each pile, and as described above, the pile is cured as a plurality of piles in the plywood factory.

[0005]

However, within a limited installation area of a plywood factory, a plurality of piles for each type of these plywood are piled up in a substantially piled state for a certain period of time (average day and night).
Curing management has a limit in the function of a plywood factory.
In addition, these piled piles are not temporarily generated but are constantly generated.

Indeed, if the piled piles for each type of plate are cured, the moisture content in one pile can be equalized, and the equilibrium moisture content can be individually achieved to some extent. However,
In fact, the water content is not equalized between the piles. Therefore, to compose plywood,
When the top plate, back plate, and middle plate are taken out of each pile and assembled into plywood, if there is a variation in the water content of each plate, poor adhesion in the post-process as described above, the product itself Will be warped. The present invention aims to solve the problems as described above by assembling a veneer veneer dried by a veneer drier into a roll, and in advance, to achieve an equilibrium moisture content between each plate as a plywood. Things.

[0007]

SUMMARY OF THE INVENTION For this reason, according to the present invention, there is provided a wound ball having a large-diameter winding reel in which two veneer veneers after drying are stacked and alternately as one set. By winding and winding the thread member as a guide,
The above problem has been solved. This is to cope with the mechanism of the five-layer plywood. Of the three veneer veneers having the same fiber direction, two are laminated and one is made a single one.
It is a set. These three veneer veneers are of different plate types, preferably each of a front plate, a back plate, and a core plate, and two front plates and a back plate are stacked on each other. 1 board
And they are wound alternately. Further, since the front plate and the back plate are almost the same in terms of grade, two identical plate types for the front plate are stacked or two identical plate types for the back plate are stacked. Sometimes.

[0008] According to the findings of the inventors of the present application, a winding reel (φ165 m) used for winding a veneer veneer before drying, that is, a veneer veneer immediately after cutting from a log.
When m) was used as it is for winding a veneer veneer after drying, it did not adapt to its small diameter, but broke from the portion parallel to the fibers, making it impossible to wind it around the winding reel itself. In particular, if cracks, cuts, and the like that occur after drying are present in the veneer veneer, the veneer will be cut off from that portion. Therefore, preferably, the diameter of the take-up reel is 3
By setting the thickness to 00 mm or more, winding of the veneer veneer after drying is improved.

As a preferred example, a large-diameter take-up reel is
A plurality of large-diameter flanges having the same diameter in the axial direction thereof are attached to the reel shaft at arbitrary intervals. In addition, a large number of openings are formed in the surface portion of each large-diameter take-up reel.

According to the above configuration, the diameter of the take-up reel itself is larger than that of the conventional take-up reel (φ165 mm) as described above (φ300 mm or more). Increased power load due to the increased weight, such as when transporting the take-up reel, winding veneer veneer, or storing the reeling deck in the wound ball stock area, is reduced by the use of flanges and openings. Has been resolved. Since the inside of the veneer veneer wound on the take-up reel having a large diameter is communicated with the atmosphere through many openings formed in the take-up reel, air permeability is achieved. Therefore, hot air, moisture, and the like inherent in the veneer veneer after drying are radiated to the atmosphere from a large number of openings, and the wound veneer veneer (two veneer veneers and one veneer veneer) are wound. While the water is stored, it is possible to promote equilibrium moisture content.

Of the veneer veneer is stopped, and the length of the veneer is determined based on the pulse amount until the rear end of the veneer veneer is detected. When the pulse amount of the distance is counted up, the drive roll is driven by the plate length, and the two laminated veneer veneers and one veneer veneer are alternately wound on the take-up reel using the thread member as a guide. The problem is solved by winding.

[0018]

Embodiments of the present invention will be described below with reference to the accompanying drawings. First, a case where the veneer veneer after drying is once wound and rolled to form a ball will be described with reference to FIGS. 1 and 2. At the veneer veneer rewind position 3, bearing portions at both ends of a take-up reel 4 are rotatably supported by a reel receiver 5 on the wound ball 2 on which the dried veneer veneer 1 is wound. A support shaft 6 is supported below the ball 3 and a plurality of large-diameter base end pulleys 7 are attached at arbitrary intervals in the axial direction of the support shaft 6. A pair of support arms are rotatably supported on both sides of the base pulley 7 on the support shaft 6, and the small-diameter distal pulley 8 can be rotated within the interval between the tips of the pair of support arms. I support it. Each large diameter base end pulley 7
The drive guide band 9 is wound between the small-diameter tip pulleys 8 and the small-diameter tip pulleys 8, respectively, and the tip pulley 8 is turned in the direction of the winding ball 2 with the support shaft 6 as a fulcrum.
Is pressed against the lower part of the outer circumference. When the drive guide band 9 is rotated counterclockwise in FIG. 1, the veneer veneer 1 is rewound by the frictional force between the wound ball 2 and the drive guide band 9. The unwinded veneer veneer 1 reaches the return guide member 10 while being transferred onto the drive guide band 9, is folded in a Z-shaped transport direction, and reaches the transport conveyor 11.

The veneer veneer 1 is conveyed on a conveyor 11 with its fiber direction intersecting the conveying direction, and the position thereof is regulated during the conveyance by position regulating means 12 installed in parallel with the conveyor 11. Become. The position regulating means 12 is provided with a first regulating belt 13 having a vertical shape parallel to the conveyor 11 on one side in the conveying direction of the conveyor 11, and the side of the veneer veneer 1 being transported on the other side. It has a pressing body for pressing. The pressing body presses a side portion of the veneer veneer 1 that intersects the conveying direction and moves the veneer veneer 1 toward the first regulating belt 13 to regulate the position. The pressing means may be moved forward or backward in a direction intersecting with the conveying direction by the fluid motion, or may be eccentric within the interval of the vertical second regulating belt 14 installed in parallel with the conveying direction of the conveying conveyor 11 as shown in the figure. By bearing the ring 15 and rotating the eccentric ring 15. Due to the rotation of the eccentric wheel 15, the surface of the second regulating belt 14 moves in a direction intersecting the conveying direction, and the veneer veneer 1 is pressed against one side of the conveying direction against the surface of the second regulating belt 14, and The position is regulated by the first regulating belt 13 which rotates in the same direction.

At the end of the transport conveyor 11, a switching conveyor 16 that swings at an arbitrary angle with the end position as a fulcrum.
Is installed. The leading end of the switching conveyor 16 communicates with the starting end of a lower conveyor 17 in which the conveying path of the veneer veneer 1 goes straight or with the starting end of an upper conveyor 18 in which the conveying path of the veneer veneer 1 goes upward. ing. Therefore, the veneer veneer 1 transported on the transport conveyor 11 is alternately loaded into the lower conveyor 17 and the upper conveyor 18 by the operation of the switching conveyor 16. The position of the front end portion of each of the loaded veneer veneers 1 on the lower conveyor 17 and the upper conveyor 18 is aligned.

A polymerization conveyor 19 is connected to a downstream position of the lower conveyor 17, and the veneer veneer 1 on the lower conveyor 17 is transferred in a straight state. On the other hand, a guide conveyor 20 that guides the veneer veneer 1 on the upper conveyor 18 to the conveying surface of the overlap conveyor 19 is provided at the end position of the upper conveyor 18. The guide conveyor 20 has a downward slope in the transport direction, and the leading end thereof is maintained close to the transport surface of the polymerization conveyor 19. On this polymerization conveyor 19, the veneer veneer 1 transported straight from the lower conveyor 17 and the veneer veneer 1 transported from the upper conveyor 18 via the guide conveyor 20 are stacked with their front ends aligned. It will be polymerized.

A veneer veneer take-up position 21 for winding the two veneer veneers 1 is formed downstream of the polymerization conveyor 19. At the veneer veneer winding position 21,
A drive roll 22 having an upper surface height substantially the same as the conveying surface of the polymerization conveyor 19 and having a length at least in a direction intersecting the conveying direction of the veneer veneer 1 is carried.
The drive roll 22 can change the speed, but in a normal state, is controlled at substantially the same speed as the polymerization conveyor 19 and can rotate. Above the drive roll 22, bearing portions at both ends of a take-up reel 23 having a large diameter are rotatably supported by a reel receiver 24. The take-up reel 23 has its lower surface fixed to the drive roll 22.
1, the drive of the drive roll 22 is driven by the frictional force, and rotates in the counterclockwise direction in FIG. 1. Downstream of the take-up reel 23, a plurality of thread member feeding-in mechanisms 25 are provided at arbitrary intervals in the longitudinal direction of the take-up reel 23.

The two-ply veneer veneer 1 is conveyed on a polymerization conveyor 19 and reaches a veneer veneer winding position 21. At this time, the yarn member 2 unwound from each of the winding wheels 26 of the yarn member feeding mechanism 25 is mounted on the take-up reel 23.
The tip of 7 is wound at a plurality of locations at arbitrary intervals over its longitudinal direction. When the two-ply veneer veneer 1 reaches between the drive roll 22 and the take-up reel 23, the drive of the drive roll 22, which is rotating at substantially the same speed as the polymerization conveyor 19, is driven, and the take-up reel 23 is driven. The veneer 1 is rotated in the opposite direction, and the two-ply veneer veneer 1 is wound up using the thread members 27 at a plurality of locations as guides. The two-ply veneer veneers 1 conveyed from the polymerization conveyor 19 are sequentially wound up on a take-up reel 23.

More specifically, a winding mode around the take-up reel 23 as shown in FIG. 3 is employed. That is, the take-up reel 23 is provided with a high friction area such as a sandpaper or a convex portion at which the thread member 27 is entangled at a plurality of places at arbitrary intervals in the longitudinal direction. Further, a plurality of thread member feeding nozzles 27N are provided on the downstream side of the take-up reel 23 from a position slightly above the outer periphery of the take-up reel 23 to a position below, for example, an arc-shaped guide rail (not shown). ), Or a mechanism that can move up and down freely (not shown)
To make it freely displaceable. On the other hand, the drive roll 22 has grooves 22M for storing the tips of the nozzles 27N at a plurality of locations at arbitrary intervals in the axial direction. First, the tip of the thread member 27 unwound from the pinwheel 26 is sprayed onto the high friction area of the take-up reel 23 via the nozzle 27N located above, so that it is entangled. The roll 22 is moved to each groove 22M. At this time, the nozzle 27N is lower than the upper surface of the drive roll 22, and the thread member 27
There is tension between them. Therefore, veneer veneer 1
When the drive roll 22 is driven by the frictional force to wind the drive roll 22 onto the take-up reel 23, the drive roll 22 is wound at a plurality of positions from the leading end thereof with the thread member 27 as a guide (see FIG. 4).

At the time of winding on the take-up reel 23, there is a case where the front-back distance of the veneer veneer 1 to be wound is reduced in consideration of the winding efficiency. This front / rear interval filling means will be described with reference to FIG. A pulse transmitter 28 is provided on the polymerization conveyor 19, and a contact type or a non-contact type detector 29 such as a transmission type or a reflection type is disposed above the polymerization conveyor 19. The drive controller 30 is connected to a distance setting unit 31 that sets a distance K from the position of the detector 29 to the drive roll 22, and is read as a pulse amount of the distance K by reading a pulse amount from the pulse transmitter 28. ing. When the detector 29 detects the front end portion of the veneer veneer 1 (the front plate and the back plate) conveyed on the polymerization conveyor 19, the detection command is sent to a drive controller 30 which is a control system of the drive roll 22. send. Drive controller 30
A plurality of storage elements are built therein, and the above-described detection command is written into one of the storage elements to stop driving the drive roll 22. When the veneer veneer 1 (the front plate and the back plate) is conveyed over the overlapping conveyor 19 by a distance K and the storage element detects this by counting up the pulse amount, the drive roll 22 is activated, and the storage element is removed. Resetting. The veneer veneer 1 (the front plate and the back plate) reaching the drive roll 22 is wound around the take-up reel 23 by using the thread member 27 as a guide by driving the drive roll 22 by the length of the plate. The length of this veneer is such that the veneer veneer 1 (front and back) is
The detector 29 detects the front end and the rear end at the time when the sheet is conveyed on the top 9, and this is detected in the drive controller 30 as a pulse amount. Since the plate length is cut into a substantially fixed length, the length of the fixed length is determined in advance by the drive controller 30.
It may be stored as the plate length 32 inside.

When the pulse amount corresponding to the plate length 32 is counted up, a drive stop command is transmitted from the drive controller 30 to the drive roll 22, and the drive roll 22 stops again. Then, the veneer veneer 1 (the front plate and the back plate) made of the next two sheets is conveyed on the polymerization conveyor 19,
When the front end is detected by the detector 29, the same process as described above is performed. In this case, suppose that the leading 2
If the laminated veneer veneer 1 (the front and back plates) is still in the process of transporting the polymerization conveyor 19 or winding it around the take-up reel 23, another storage element is not reset because the preceding storage element has not been reset. Pulse control is performed by the storage element. Thus, the next two-ply veneer veneer 1
(The front plate and the back plate) are wound on the drive roll 22 and the thread member 26 is used as a guide in a state where the gap between the back end of the veneer veneer 1 (the front plate and the back plate) wound previously is reduced. It is wound around the reel 23. By repeating the above operation, the drive roll 22 rotates intermittently, and the two-ply veneer veneer 1 is taken up by the take-up reel 2 as shown in FIG.
3, it can be efficiently wound with the front-rear space being tight.

The next veneer veneer 1 has a detector 1
5, the yarn reaches the drive roll 6 through the same process as described above, and as shown in FIG. 6, the yarn is wound in a state where the gap with the rear end of the veneer veneer 1 wound last time is filled. It is wound around the take-up reel 7 using the member 12 as a guide. By repeating the above operation, the drive roll 6
Rotates intermittently, and the veneer veneer 1 can be efficiently wound on the take-up reel 7 with the front-rear space being tight.

The front-rear spacing means shown in FIG. 5 intermittently rotates the drive roll 22 at the veneer veneer winding position 21 and winds it on the take-up reel 23. If the winding speed (low speed) substantially corresponds, there is no problem in winding, but there is a problem in increasing the winding speed. In this case, during the transportation in the stage before the veneer veneer winding position 21,
The leading and trailing spaces are to be filled. Next, another embodiment of the front-rear spacing means will be described with reference to FIG. still,
The same parts as those in FIG. 5 are denoted by the same reference numerals. First, the starting end of the space-filling conveyor 19K for performing front-to-back space packing is set so as to be intertwined with the end part of the overlapped conveyor 19, and both conveyors 19K and 19 are set to be independently drivable. Under this condition, when the detector 29 installed on the polymerization conveyor 19 detects the front end portion of the veneer veneer 1, this detection command is transmitted to the drive controller 30 which is a control system of the interval shortening conveyor 19 </ b> K. . This drive controller 3
0 is connected to a distance setting device 31 that sets a distance K from the detector 29 to an arbitrary position of the space-filling conveyor 19K, and based on the detection command, the distance-filling conveyor 19K.
Stop driving. A pulse transmitter 28 is provided on the polymerization conveyor 19, and the veneer veneer 1 is connected to the polymerization conveyor 1.
9 is conveyed by a distance K, which is detected by counting up the pulse amount. Spacing conveyor 19
In the veneer veneer 1 that has reached K, the space-filling conveyor 19K is driven by the length of the veneer veneer. When the veneer veneer 1 is conveyed on the polymerization conveyor 19, the detector 29 detects the front end and the rear end of the veneer veneer 1 and captures them in the drive controller 30 as pulse amounts. by. Since the plate length is cut into a substantially fixed length, the fixed length may be stored in advance in the drive controller 30 as the plate length. Due to this intermittent drive, the veneer veneer 1 is closely spaced in the front-rear direction on the space-filling conveyor 19K, and is separately transferred to a conveyor and wound on the take-up reel 23 at a speed matching the winding speed. is there.

At this time, if the position of the reel receiver 24 bearing the take-up reel 23 is fixed, the polymerization conveyor 19 and the drive roll 22 can be pivoted downward about the starting end position of the polymerization conveyor 19 as a fulcrum. The drive roll 22 is automatically turned and lowered together with the polymerization conveyor 19 by the radius of the winding diameter that increases. Conversely, if the position where the drive roll 22 is supported is fixed, the position of the reel receiver 24 that supports the take-up reel 23 is raised by the radius of the increased winding diameter. . The drive roll 22 applies a frictional force to the take-up reel 23, so that the take-up reel 23 is always kept at a constant pressure by a fluid motion or a balance weight.
Is kept in contact with

Further, the veneer veneer 1 after drying is wound on the take-up reel 23, and a φ165 mm take-up conventionally used for winding veneer veneer 1 immediately after cutting from a log. It was impossible to use the reel as it was. That is, when the dried veneer veneer 1 is wound around this take-up reel having a diameter of 165 mm, the veneer does not conform to its small diameter, but breaks from a portion parallel to the fiber, and cannot be wound around the take-up reel itself. In particular,
If cracks, cuts, or the like that occur after drying are present in the veneer veneer 1, the veneer veneer 1 will be cut off from that portion. According to the findings of the inventor of the present application, the winding of the veneer veneer 1 after drying is good by setting the diameter of the winding reel 23 to at least 300 mm or more. In the above embodiment, the diameter of the take-up reel 23 is set to φ450 mm,
The laminated veneer veneer 1 after drying is wound up.

In this manner, the mechanical wound ball 33 wound as a two-ply veneer veneer 1 and assembled on the front and back plates constituting a three-layer plywood is a mechanical wound stock area of a reeling deck. Transferred to This structured ball stock area is composed of beams installed in multiple stages in the vertical direction.
Day and night) multiple water is stored and the equilibrium moisture content between the front and back plates is to be increased.

In the above embodiment, the veneer veneer rewind position 3
Describes a case in which a fixed-size dried veneer veneer 1 is rewound one by one from one rolled ball 2 and the two are stacked one on another. This is because the front plate and the back plate are almost the same in grade, so that two identical plate types for the front plate are stacked or two identical plate types for the back plate are stacked. It is by doing. At this time, if the veneer veneer 1 after drying is in a continuous state, the veneer veneer 1 is cut to a fixed size when being conveyed on the conveyor 11.

In FIG. 8, at a veneer veneer rewind position 3, a fixed-size dried veneer veneer 1 is obtained from two rolls 2 of different plate types (for the front plate and the back plate). Are rewound one by one, and the two are stacked to form an embodiment. In this case, the same conveyor 11 as described above, and the position regulating means 1 installed in parallel with the conveyor 11
2 are individually installed so as to be upper and lower two stages for the front plate and the back plate, respectively, and guide the veneer veneer 1 to the conveying surface of the polymerization conveyor 19 at the end of the upper conveying conveyor 11. It is enough to install 20. For convenience of explanation, the lower conveyor 11 is used for the front plate, and the upper conveyor 11 is used for the back plate.

In this case, at the veneer veneer rewinding position 3, one fixed-size dried veneer veneer (front plate and back plate) is removed from two rolls 2 (for the front plate and the back plate). Rewind one by one,
It is transferred onto the upper and lower conveyors 11. The veneer veneer 1 (front and back) is the upper and lower conveyors 1
The position is regulated by the position regulating means 12 on each of them.
Thereafter, on the polymerization conveyor 19, the veneer veneer 1 (front plate) straight-forwarded from the lower conveyor 11,
The veneer veneer 1 (back plate) conveyed from the upper conveyor 11 via the guide conveyor 20 is superposed on two veneers with their front ends aligned. Next, the two-ply veneer veneer 1 (the front plate and the back plate) is wound up by the above-described spacing reducing means while keeping the front-rear spacing close, and is stored as the mechanical wound ball 33 in the mechanical wound ball stock area. In this case, the equilibrium moisture content of different plate types (for the front plate and the back plate) can be improved.

Each of the above embodiments describes a case in which two veneer veneers 1 after drying are stacked one on top of the other and wound up in a state where the distance between the veneer veneers 1 is large. This consists in assembling a front plate and a back plate constituting a three-layer plywood. Next, a description will be given of an embodiment in which each of the top plate, the core plate, and the back plate constituting the five-layer plywood is formed into a mechanical ball. This is, as schematically shown in FIG. 9, as described above, on the large-diameter take-up reel 23, alternately, by stacking two veneer veneers 1 after drying and alternately as a set of one veneer veneer.
