The present invention is a glue valve for supplying adhesive yarns used in an apparatus for producing transverse veneers by sticking adhesive threads on the surface of a short, small-sized veneer obtained by shaping irregularly-shaped veneers and joining them together. The thread glue valve is configured to move up and down individually. Furthermore, by using a thread glue valve provided longitudinally with a yarn path on the front side of the main body block that supplies the adhesive, and removably provided with a mixing plate that covers the yarn path, maintenance such as thread reassignment is safe. Can be done easily and quickly.
It is a thread glue valve configured to stick an adhesive thread to the surface of a veneer from the tip of the thread path.
Hereinafter, an embodiment in which the present invention is applied to a system for joining unformed veneers to produce a transverse veneer will be described. This is a system for manufacturing a single-sided veneer by joining non-formed single-plates including a series of the non-formed single-plate loading mechanism A, the small-sized single-plate shaping mechanism B, the side-lifting mechanism C, and the loading mechanism D.
This horizontal veneer single-plate manufacturing system is a system that is safe as a whole and improved in production efficiency by improving and combining the element devices of each mechanism.

In the unformed veneer transport mechanism A, a defect or an end veneer is supplied from a previous process such as a stacker or slicer, and a transport mechanism is configured by a belt conveyor.
In the small-sized single-plate shaping mechanism B, the cutting width of the defective portion to be cut is set so as to be within the allowable defect range after the cutting. Even if there is a small defect in the horizontal single-layer veneer, as a matter of course, the yield is improved by reducing the number of cut-off portions.
Further, in the small-sized single-plate shaping mechanism B, the attachment shaft of the movable blade of the clipper divided into two pieces was attached to the lower edge portion of the angular shaft with the angular shaft of a square pipe or the like. Conventionally, since it was attached to the lower part of the round pipe, the attachment position can not be seen from the upper side of the crowded equipment, and the processing of the fixing jig is difficult because of the circular arc, requiring skill. By using a square pipe, the movable blade can be attached at a position where it can be easily seen, stable attachment can be easily performed, and maintenance such as replacement can be facilitated.
In the present system, the angular axis refers to an axis from which the surface of the axis to which the movable blade is attached protrudes at a right angle. Even if the place other than the mounting surface is a curved arc, it does not affect the maintenance work.

In the transverse displacing mechanism C, a plate in which a plurality of grooved feed portions are formed by cutting out in a comb shape, which is a divided plate, is used for a spot valve that extrudes a thermoplastic molten adhesive in a dot shape. Since the edge of the plate is a plurality of groove-like notches, maintenance such as cleaning becomes easy in a short time by brushing from the open side of the groove. As the trouble processing time becomes shorter, the temperature drop of the plate becomes smaller, the temperature drop of the thermoplastic adhesive can be minimized, and the adhesion failure at restart can be avoided. Maintenance takes only a short time, and even if a problem occurs, the interruption time due to this device is reduced, and the overall system operation rate is improved. In addition, the maintenance becomes easy, the safety of the workers is improved, the skill required for the workers is lowered, and it is possible to cope with the labor shortage.
Conventionally, it is a head plate in which many small holes for supply are arranged in a row, and when it is clogged, the work of scraping the plate heated to a high temperature by molten adhesive with a hand from the small hole is a detailed operation. It was over. It was hot and dangerous, taking a long time for maintenance, and also taking time for a restart.

In the wefting mechanism C, three to six thread glue valves for supplying adhesive threads are provided on the mounting bar. The thread glue valve forms a thread path in the vertical direction by a mixing plate detachably attached to the main body block, and improves thread replacement and cleaning performance.
The thread glue valve is mounted to be able to move up and down individually with respect to the mounting bar. The thread glue valve can be moved up and down individually, the mixing plate can be removed for handling, and troubles such as thread breakage can be performed safely in a short period of time.
Conventionally, even if one trouble such as thread breakage occurs, it is necessary to rotate and raise the entire mounting bar which is the frame of the horizontal displacement device to open, connect the yarn, recover and restart. Due to the influence of the high temperature of the molten adhesive, it took a risk and time.

With regard to the tank that supplies the thermoplastic adhesive in the lateral peeling mechanism C, the heating of the tank that melts the thermoplastic adhesive is controlled by the bottom heater and the servomotor of the present system (size clipper, scrap divider, size clipper Servo motor) is provided with an auxiliary heater based on regenerative power obtained by regenerative braking.
The entire glue tank is uniformly heated, and the tank volume can be reduced. In addition to saving energy and space by using a small capacity tank and regenerative electric power, the thermoplastic resin adhesive stays in the tank in a molten state for a short time, and is used in a fresh state without deterioration. Fewer problems are caused.
Conventionally, heating is performed with a heater from the bottom of the tank using a commercial power supply or a power supply of the generator, the temperature distribution in the tank is uneven, and a large amount of adhesive is melted to ensure usable capacity. The melt state or partial retention occurred for a long time.

  This system has a basic process in common with Patent Documents 1 to 4. The outline of the process of this system is that the front and rear edges are not straight as disclosed in Patent Document 5 and it is not straight, and there are nodal holes and rots on the way, so the length of the specified dimension can not be ensured From the defective veneer, the edge is cut and shaped into a straight line, and the defective part in the middle is cut off to obtain a small-sized veneer that does not meet the fixed size, and the small-sized veneers are joined together to obtain a fixed size It is a process of shaping and stacking, and is sent to a post-process related to plywood manufacture such as a structural process.

[System outline]
This will be described below with reference to the drawings.
FIG. 1 shows the overall configuration of a system for producing a horizontal veneer of this system. Fig.1 (a) is a top view, (b) is a side view. A side view of the device arrangement is described in FIG. 2 (b).
From the left of the drawing, it is a system for manufacturing a single-transverse veneer having the respective mechanisms of an unformed single-plate loading mechanism A, a compact single-plate shaping mechanism B, a lateral stripping mechanism C, and a loading mechanism D.
The non-forming veneer loading mechanism A is a mechanism for incorporating the non-forming veneer separated from the fixed-size veneer in the previous process into the horizontal veneer production system. Ruler vertical belt 2b having a vertical belt surface for bringing the side edges of the unformed veneers into contact with the infeed belt conveyor 1 which transfers the unformed veneers horizontally and sends them horizontally, the upper surface of the unformed veneers It has a chain type ruler 2a which slides to the side and is brought close to the ruler vertical belt 2b.

  The small-sized single-plate shaping mechanism B has a function of detecting a defective portion existing in an unformed single-layered plate and cutting out the defective portion. The light projector 5b is disposed below the single plate conveyance path, the light receiver 5a is provided above the conveyance path, a defect is detected by transmitted light, and the contact-type thickness gauge sensor 6a is disposed on the upper surface side of the conveyance path. A thickness gauge 6 is provided to detect defective portions where the unformed veneer is thin, and a small-sized clipper 7 is disposed which cuts out the detected defective portions and thin defective portions. A control device 32 is provided to determine the extent to which the continuously conveyed unformed veneer is cut off, to stop at the cutting position and to operate the small clipper 7. In the small-sized single-plate shaping mechanism B, the transport system is provided with endless chain conveyors (3a, 3b) at the top and bottom, and controlled by the control device 32 by the servomotor 4 with carry-in drive reduction gear. The part stops at the cutting position of the small clipper 7. The invariable clipper 7 also drives the movable blade 7a in synchronization with the stop of the unformed veneer by the control device 32. The unformed veneer is stopped, cut and carried out intermittently at the position of the small clipper 7 and the defective portion is cut off to become a small sized veneer. Blanks are eliminated, and the shaped small veneers are sent to the next stripping mechanism C.

The transverse displacing mechanism C is a mechanism for joining together the small-sized veneers shaped in the previous step to reconcile the transverse slats with a fixed length. Hot melt adhesion in which a melting thermoplastic adhesive is attached to the end face of a back and forth small-sized veneer to be sent, butted, end face bonding is performed, and then a melting thermoplastic adhesive is attached. The agent-impregnated yarn is adhered to the upper surface of the short veneer, to form a continuous veneer, and thereafter, it is cut into a fixed length by the fixed clipper 20.
The lateral stripping mechanism C is provided with a transport system including a scrap divider 9, upper and lower endless chain conveyors 11a and 11b, and a synchro drive 13. Each servo motor 10 with a scrap divider elevating drive reducer and a servo with a delivery conveyor drive reducer The motor 12 and the servo drive 14 with synchro drive decelerator are controlled by the controller 32. By adopting the synchro drive 13, it becomes possible to synchronize a single plate softer than before as well, and it is possible to improve the yield by reducing the number of cut-off portions.
Bonding is performed by means of a spot glue valve 18 which supplies spot-like end adhesive supplied from a spot valve 16 disposed below the transport path and a hot melt adhesive impregnated yarn from the upper surface of the transport path. An adhesive supply device 15 is provided, which comprises a thermoplastic resin pellet melted and supplied to the spot valve 16 and the yarn paste valve 18 by a hot melt glue tank & pump 15a.
The transversely veneered veneers which have been joined to form a continuous shape are cut into a fixed length by the fixed size clipper 20 and are sent to the subsequent stage by the fixed size conveyor 22.
The loading mechanism D is deposited in a stacker 23 provided with a deposition table lifter 28 downward. The stacks can be stacked stacked on one side or aligned on the other side.

  An overview of the processing of the veneer according to the present system for producing a side veneer is shown in FIG. 10 (a). A narrow single-piece plate with no defects, by cutting out defective portions such as irregularities and chipping of the front and rear ends present in the irregularly-shaped veneer 41c and defective portions such as nodal holes at the veneer cutting positions a, b, c, d, e. 31b is manufactured, and a point-like end face adhesive 16f is attached to three end faces of this small-sized veneer, and point-joined, and then two hot melt glue-impregnated yarns 17c are placed on the surface of the single-plate. Affixing and making a continuous horizontal veneer 31c. In this system, the continuous horizontal veneers 31c are cut into a fixed size and stacked in a stacker as a fixed horizontal veneer.

[Size single-plate shaping mechanism B]
FIG. 2 is a view showing a detection state (a) of a single plate detecting a defective portion existing in an unformed veneer in the small-piece shaping mechanism B and cutting out the defective portion and a small-plate shaping mechanism (b) It is.
In this system, cutting control is performed leaving an acceptable defect. For example, if the allowable defect width is an allowable width dmin and the measured defect width dn is smaller than the allowable width dmin, the width of the defective portion is not cut off but is large. In such a case, the width of the defect after excision is cut off so as to be less than the allowable width.
Two unformed veneers 41a and 41b are illustrated in FIG. 2 (a). In the unformed veneers 41a, irregular end faces are in front and back, and large holes due to large rot in the middle portion and It is shown that there are large and small nodal holes. The unformed veneer 41b is shown to have two large and small cracks at the edge of the middle part.
When control of defective part cutting of this system is applied to the unformed veneers 41a and 41b, since the front and rear ends are irregular, there are cutting points c1, c6, c7 and c10. Defects in the middle part are not cut off for nodal holes having a width d4 smaller than the allowable width dmin of the defect and a small width d1.
This improves the yield of the length based on the tolerance dmin remaining at least in the middle cut portion. The allowable width dmin is determined by the quality of the plywood and the user's request.
Furthermore, when the defect width d5 due to large rot overlaps with the spot position of the end face bonding, the condition of the position and the shape of the defect portion such as cutting largely by c2 and c3 without leaving the defect portion is added to set the cutting condition can do.
For the large nodal hole width d4, the cut points c4 and c5 are determined so that the portion Δa + Δb remaining after the excision is equal to or less than the allowable width dmin. Similarly, for the large crack width d2, the cut points c8 and c9 are determined so that the remaining part Δc + Δd becomes equal to or less than the allowable width dmin.
When the ablation width is dc, the ablation control of the intermediate defect is determined as follows.
(1) dn d dmin → without cutting.
(2) dn> dmin → dc = dn-dmin

FIG. 2 (b) shows a transfer system for the small-sized single-plate shaping mechanism B and the lateral stripping mechanism C further downstream.
A transfer system 11 for the small-sized single-plate shaping mechanism is formed such that the single plates are nipped and transferred by endless chain conveyors disposed above and below the single-plate transfer path T. The upper chain conveyor 11a and the lower chain conveyor 11b are formed. The small single-plate shaping mechanism transport system 11 includes a carry-in drive speed reducer-equipped servomotor 4 and is intermittently driven.

In the small clipper 7 of the present system, the fixed blade 7d is disposed below the transport path T, and the movable blade 7a is disposed above the transport path T. It is stopped and the movable blade 7a is dropped and cut.
In the movable blade 7a, a movable blade 7c is detachably attached to a movable blade base 7i attached below the knife holder 7b which is an angular shaft having a rectangular cross section. The movable blade body 7c is adjusted and replaced as needed since the adjustment of the protrusion length of the blade and wear and chipping due to use occur.
In this system, the vertical surface of the movable blade base 7i is along the side surface of the rectangular knife holder 7b, and the other surface is set along the bottom surface of the knife holder 7b. The corner portion of the movable blade stand 7i is located at substantially the same position as the lower end of the rectangular cross section of the knife holder 7b, and the lower surface of the knife holder 7b is in surface contact with one surface of the movable blade stand 7i. . It is important that the lower surface of the knife holder 7b and the side surface on the movable blade side be formed in a plane orthogonal to each other, and the shape of the other surface is arbitrary.
Since the movable blade 7c is attached to the vertical surface of the movable blade base 7i and can be seen well without being hidden by the lower surface of the knife holder 7b, maintenance of replacement and adjustment is easy.
The movable blade 7c has an elongated hole in the blade. The movable blade guide 7f is brought into contact with the upper surface of the movable blade 7c, and the movable blade guide mounting bolt 7g is tightened. The rear end surface of the movable blade 7c is pushed, and adjustment is performed by the movable blade pressing bolt 7e which adjusts the protrusion length of the blade.
The small clipper 7 has a length for cutting the entire length of the veneer, and has a long width as illustrated in the plan view 7 (b). The length is generally 140 to 350 cm according to the standard of plywood, and divided into two or so and partially adjustable.

The molten hot melt adhesive is supplied from the lower unit valve 16d to the adhesive supply groove 16e, and is raised in a point shape on the single sheet conveyance path. The state is shown in (d). The small-sized veneer 31b adheres a point-like end face adhesive 16f to the front end during conveyance. The front end of the small-sized veneer 31b is guided by the tapered surface to skim the end face adhesive 16f.
The rear end of the single-piece plate 31 b is temporarily stopped at a location where the spot valve 16 has passed, and is brought into contact with the leading end of the small-piece single plate to be fed later to be joined.

As described above, the spot valve 16 is a mechanism for supplying the molten hot melt adhesive, and the comb plate 16a and the plate 16b are at high temperature. The adhesive supply groove 16e rubs directly on the veneer, which may cause troubles such as clogging by wood powder or the like. The comb plate 16a can be removed from the plate 16b and can be scraped off with a brush or the like from the open part of the groove. Regular cleaning can be done as easily.
By dividing the spot valve 16 of this system into the plate 16b and the comb-like plate a provided with a large number of grooves, maintenance and the like can be easily performed in a short time.

FIG. 4E shows an example of a conventional spot valve 160. As shown in FIG.
The conventional spot valve 160 is porous in which a body block 160c and a unit valve 160d are disposed below and a plate 160b having an adhesive supply hole 160e formed thereon is disposed. A large number of small holes are provided at the top of one plate 160b, and the molten hot melt adhesive is supplied in the form of dots from the holes.
Because it is a small hole, it is necessary to scrape out troubles such as clogging and regular cleaning processing with a cone-shaped jig one by one, and since it becomes difficult to take when the adhesive hardens, it is necessary to handle at high temperature, It is a task that requires time and attention.
Since the spot valve 16 of this system divides the plate and forms a large number of small grooves along the sides, cleaning etc. can be performed easily and quickly, and maintenance can be performed safely without lowering the temperature of the high temperature member so much. The restart can be performed quickly.

[Adhesive supply equipment]
FIG. 9 shows an example of the adhesive supply device 15 of the present system. FIG. 9A shows a plan view of the adhesive supply device 15, and FIG. 9B shows a side view of the adhesive supply device 15. As shown in FIG.
The adhesive supply device 15 is a device that heats and melts a pellet-like thermoplastic resin adhesive and supplies it as a liquid thermoplastic adhesive to the spot valve and the yarn glue valve.
The adhesive supply device 15 includes a hot melt glue tank & pump 15a having a built-in pump, a pellet supply device 15b with a lid 15e for supplying pellets to the glue tank, and a hot melt glue tank & pump 15a for supplying a melted adhesive. The spot valve supply pipe 15 h and the glue valve supply pipe 15 i are provided.

The block heater generates heat using a normal power supply. The regenerative heater 15f generates heat using the regenerative power of the servomotor used in the system for manufacturing the single-transverse single plate.
In the illustrated example, regenerative heaters 15f are disposed on both sides and the back of the hot melt glue tank & pump 15a.
The pellet feeder 15b is provided with a pellet feeder vibrator 15d to feed pellets to the hot melt glue tank & pump 15a as needed.
The regenerative heater generates heat when the system is operated as an auxiliary heater, and in addition to the auxiliary heating of the adhesive, the temperature distribution in the hot melt glue tank & pump 15a is uniformed, energy saving and the hot melt glue tank & pump 15a contributes to miniaturization and stabilization of adhesive quality.

The block heater strongly generates heat and melts the pellet, but the temperature near the heater tends to be high, and it tends to be low at the periphery, and in order to supply the adhesive stably, the size increases and a large amount of stock is It is operating with holding. In such a state, stagnation occurs at the corner of the tank, and the use of non-fresh adhesive occurs, such as remelting of the solid adhesive that has been left unused. Such adhesives degrade in quality and cause troubles.
In this system, regenerative power is used to heat the area including the upper side of the glue tank to the periphery that can not be covered by the block heater while the system is in operation, and the adhesive in the glue tank is uniformly melted You can keep it.
For this reason, even if the glue tank is downsized, the amount of usable melt adhesive can be secured sufficiently, and if the glue tank capacity is reduced, the block heater can be downsized, and energy saving can be achieved. The melt adhesive, which decreases as the glue tank is miniaturized, is replenished by operating the pellet feeder vibrator 15d as needed. A sensor or the like that detects a drop in the liquid level can be provided to automatically replenish the level. In the past, since the capacity was large, it was the frequency at which the workers confirmed and refilled batchwise before starting in the morning, before restarting in the afternoon, etc.
The ability to miniaturize the high temperature glue tank is also useful for saving space and improving workability.

The continuous horizontal veneers 31c are cut to a fixed size and stacked in a stacker as a horizontal fixed veneer 31d.
An example of the horizontal fixed measure veneer 31d is shown in FIG. 10 (b).
In the illustrated example, five small-sized veneers 31b are joined to form one horizontal fixed-size veneer 31d. A large number of point-like end face adhesives 16f bonded by the spot valve 16 are present on the joint end face, and there are hot melt glue-impregnated yarns 17c formed in three rows on both sides and the center on the surface.

[Loading mechanism D]
The loading mechanism D of this system is to deposit the horizontal fixed single plate 31d formed in the previous step on the stacker 23 provided with the deposition table lifter 28. The accumulated horizontal single-ply veneer will be subjected to a plywood manufacturing process such as a plywood structure process.
An example of the stacker 23 used by the loading mechanism D of this system is shown in FIG.
The stacker 23 has a single-plate conveying device 24 at the top, and a deposition table lifter 28 on which the single-wafer fixed single-plate 31d is placed and deposited, and the single-wafer single-wafer single-plate 31d carried above the table lifter. It consists of a braking device to be dropped.

FIG. 11A shows a front view of the stacker.

The left and right stacker gates 24c, 24d can be opened and closed differentially or simultaneously.
When the left and right stacker gates 24c and 24d are differentially opened and closed, the posture of the veneer is inclined to the side portion opened earlier and drops, so that the drop speed is high and deposition is offset. If the left and right differentials are made alternately, the offsets alternate, which makes it easy to stack. On the other hand, when it is simultaneously released, the air layer on the lower surface of the single plate becomes a resistance, and it takes time to deposit. Although it may shake somewhat to the left and right, basically the sides of the deposition veneer are aligned, which is suitable for stacking.
