The horizontal peeling according to 1. or 2. is characterized in that external power and regenerative power generated from this system are used as a heating source for the adhesive supply device that melts the thermoplastic synthetic resin adhesive and supplies it to the horizontal peeling mechanism. Single plate manufacturing system.

1. 1. By integrating and combining the improved elemental equipment of each process, we have realized a manufacturing system for manufacturing horizontal veneer that is safe and improves manufacturing speed.
2. First of all, quick loading of the final process is indispensable for improving the speed of the entire system, so we adopted a receiving bar method that opens and closes, and shifts the opening and closing timing of the left and right receiving bars to make a standard veneer. Was tilted and dropped onto the stacker. Further, by alternating the opening and closing timings, the inclination is also reversed, and the stacker is displaced according to the direction of the inclination, so that the stacking can be performed in a shifted manner. On the left and right sides of the stacker, regulated members such as a frame that allows for stacking more than the width of a standard veneer should be provided to prevent the stacker from being scattered more than necessary.
3. 3. In step B, by setting the excision width of the defective portion to be excised so as to be within the acceptable defective range after excision, the truncated portion is reduced and the yield is improved. Further, in step B, the attachment shaft of the movable blade of the clipper, which is divided into two or more pieces, is attached from the cylinder to the lower edge of the square shaft having a corner such as a square pipe, so that the attachment of the movable blade is easy to see. It is in position and stable installation can be easily performed, and maintenance such as replacement can be easily performed.
4. In step C, the head plate with small holes arranged in rows for a large number of spot valves that push out the thermoplastic melt adhesive in dots is a detailed work of scraping out from the small holes with a hot plate when it is clogged. It takes. By making this into a comb-shaped notch, the supply portion has a groove shape, and cleaning such as clogging can be done by scraping with a brush, which can be safely performed in a short time.
In addition, even if one trouble such as thread breakage occurs in the thread glue valves provided on the mounting bar, it is necessary to rotate the entire mounting bar, open it, recover it, and restart it. It was kept at a high temperature for molten adhesive, which was dangerous and time consuming. This has been improved to a structure that can be easily operated by raising and lowering the thread glue valve individually so that troubles can be dealt with, and the moving part is made smaller.
The thread path of the thread glue valve is provided in the vertical direction, the rear part and the front part of the thread path are divided so that the front side can be attached and detached, and the front side can be opened to troubles such as thread breakage, which can be easily performed.

5. Conventionally, the tank for melting the thermoplastic adhesive is heated by a heater from the bottom of the tank using commercial electric power or a power source of a generator. In the present invention, in addition to this bottom heater, a heater generated by regenerative braking obtained by applying regenerative braking to a servomotor that controls a sized clipper, a scrap divider, and a standard-sized clipper of the present system is added to the side surface of the tank. Since the entire glue tank is heated uniformly while the system is operating, the tank capacity can be reduced. As a result, in addition to energy saving, the time that the molten adhesive stays in the tank in the molten state is shortened, the adhesive is used in a fresh state without deterioration, and troubles caused by glue are reduced.

The present invention manufactures a horizontal veneer by joining a non-formed veneer having a series of mechanisms of a non-molded veneer carrying mechanism A, a sized veneer shaping mechanism B, a horizontal peeling mechanism C, and a loading mechanism D. It is a system.
The horizontal stripping single plate manufacturing system of the present invention is safe and the production efficiency is improved by improving and combining the elemental devices of each mechanism.
In the loading mechanism D, which is the final process, a receiving bar method that opens and closes is adopted, the opening and closing timings of the left and right receiving bars are shifted, and a means that the standard veneer tilts and falls onto the stacker is adopted to quickly load. .. Faster final stacking is essential to speeding up the overall system. Further, by alternating the opening and closing timings, the inclination is also reversed, and the stacker is displaced according to the direction of the inclination, so that the stacking can be performed in a shifted manner. On the left and right sides of the stacker, regulated members such as a frame that allows for stacking more than the width of a standard veneer should be provided to prevent the stacker from being scattered more than necessary.

In the sized veneer shaping mechanism B, the excision width of the defective portion to be excised is set so as to be within the defect range allowed after excision. Even if there is a small defect in the standard-sized veneer that is peeled off horizontally, the yield is improved by reducing the number of cut-off parts as a range that does not matter.
Further, in the sized veneer shaping mechanism B, the mounting shaft of the movable blade of the clipper divided into two pieces is a square shaft of a square pipe or the like, and is mounted on the lower edge of the square shaft. In the past, it was attached to the bottom of a round pipe, so the attachment position could not be seen from above the crowded equipment, and because of the arc, it was difficult to process the fixing jig, which required skill. By using a square pipe, the movable blade can be easily mounted at a position where it is easy to see, and stable mounting can be easily performed, and maintenance such as replacement can be easily performed.
In the present invention, the square shaft refers to a shaft on which the surface of the shaft to which the movable blade is attached protrudes at a right angle. Even if the part that is not the mounting surface is curved, it does not affect maintenance work.

In the horizontal peeling mechanism C, a spot valve that pushes out the thermoplastic melt adhesive in a dot shape is cut out in a comb shape to form a plate in which a plurality of groove-shaped supply portions are formed. Since the edge of the plate is a plurality of groove-shaped notches, maintenance such as cleaning can be facilitated in a short time by brushing from the open portion side.
Conventionally, it is a head plate in which a large number of small holes for supply are arranged in a row, and when it is clogged, the work of picking up the plate heated to a high temperature by the molten adhesive and scraping it out from the small holes is a detailed work, and it takes time. Was hanging. It was hot and dangerous, it took a long time to maintain, and it took time to restart.
Further, 3 to 6 thread glue valves are provided on the mounting bar. This thread glue valve was attached to the attachment bar so that it could be raised and lowered individually, and the mixing plate was a removable type. Problems such as thread breakage can be dealt with by raising and lowering the thread glue valve individually and removing the mixing plate, which can be safely performed in a short period of time.
Conventionally, even if one trouble such as thread breakage occurs, it is necessary to rotate the entire mounting bar, open it, recover it, and restart it, and it is kept at a high temperature for molten adhesive, which is dangerous. It took time.

In the horizontal peeling mechanism C, regarding the tank that supplies the thermoplastic adhesive, the bottom heater and the servomotor (dimension clipper, scrap divider, standard-sized clipper) of this system control the heating of the tank that melts the thermoplastic adhesive. An auxiliary heater is provided by the regenerative power obtained by applying regenerative braking to the servomotor).
The entire glue tank is heated uniformly, and the tank capacity can be reduced. By using a small capacity tank and regenerative power, in addition to energy saving and space saving, the time that the thermoplastic resin adhesive stays in the tank in the molten state is shortened, and it is used in a fresh state without deterioration, and it is used as glue. Less trouble caused.
Conventionally, heating is performed from the bottom of the tank using commercial power or the power source of a generator with a heater, and the temperature distribution inside the tank is uneven. By melting a large amount of adhesive, the available capacity is secured. It was in a molten state or partially retained for a long time.

The present invention shares the basic steps with Patent Documents 1 to 4. The outline of the process of the present invention is not straight due to lack of front and rear edges as disclosed in Patent Document 5, and there are knot holes and rots in the middle, so that the length of the specified dimensions cannot be secured as it is. From a defective veneer, cut the edge and shape it into a straight line, cut off the defective part in the middle, obtain a sized veneer that is less than the standard size, and join the sized veneers together to make the standard size. It is shaped into a veneer, stacked, and sent to a post-process related to plywood production such as a mechanism process.

[System overview]
This will be described with reference to the drawings below.
FIG. 1 shows the overall configuration of a system for manufacturing a horizontal veneer of the present invention. FIG. 1A is a plan view, and FIG. 1B is a side view. FIG. 2B shows a side view of the device arrangement.
From the left of the drawing, it is a system for manufacturing a veneer veneer having each mechanism of a non-molded veneer loading mechanism A, a sized veneer shaping mechanism B, a horizontal veneer mechanism C, and a loading mechanism D.
The non-molded veneer carrying-in mechanism A is a mechanism for incorporating the non-formed veneer separated from the standard-sized veneer in the previous process into the main horizontal veneer manufacturing system. A carry-in belt conveyor 1 on which an unformed single plate is placed and fed in the horizontal direction, a ruler vertical belt 2b having a vertical belt surface that abuts the side edge of the non-formed single plate on the side portion of the carry-in conveyor, and an upper surface of the non-formed single plate. It is provided with a chain-type ruler 2a that is rubbed to the side and brought closer to the ruler vertical belt 2b.

The sized veneer shaping mechanism B is a function of detecting a defective portion existing in the non-formed veneer and cutting off the defective portion. A floodlight 5b is placed below the veneer transport path, a receiver 5a is provided above the transport path, a defective portion is detected by transmitted light, and a contact-type thickness gauge sensor 6a is placed on the upper surface side of the transport path. A thickness gauge 6 is provided to detect defective portions in which the unformed veneer is thin, and a dimension clipper 7 for cutting off the detected defective portions and thin defective portions is arranged. A control device 32 is provided to determine a range for cutting the continuously conveyed unformed veneer, stop it at the cutting position, and operate the sized clipper 7. In the sized veneer shaping mechanism B, the transport system is provided with endless chain conveyors (3a, 3b) at the top and bottom, and is controlled by the servomotor 4 with a carry-in drive reducer by the control device 32 to cut the unformed veneer. The portion stops at the cutting position of the sized clipper 7. The sized clipper 7 also drives the movable blade 7a by the control device 32 in synchronization with the stop of the non-formed veneer. The non-molded veneer is stopped, cut, and carried out intermittently at the position of the sized clipper 7, and the defective portion is cut off to become a sized veneer. The veneer waste is removed, and the shaped veneer is sent to the next horizontal peeling mechanism C.

The horizontal peeling mechanism C is a mechanism for shaping a horizontal stripping veneer having a fixed length by connecting sized veneers shaped in the previous process. Hot-melt adhesive, in which molten thermoplastic adhesive is attached to the end faces of the sent front and rear sized single plates and abutted against each other to perform end face bonding, and then melted thermoplastic adhesive is attached. This is a mechanism in which an agent-impregnated thread is adhered to the upper surface of a short single plate to form a continuous single plate, and then cut into a standard length with a standard clipper 20.
The horizontal peeling mechanism C includes a transport system including a scrap divider 9, upper and lower endless chain conveyors 11a and 11b, and a synchro drive 13, each of which is a servomotor 10 with a scrap divider elevating drive reducer and a servo with a carry-out conveyor drive reducer. The motor 12 and the servomotor 14 with a reducer for synchro drive are controlled by the control device 32. By adopting the synchro drive 13, it becomes possible to finely synchronize a veneer that is softer than the conventional one, and it is possible to reduce the number of cut-off portions and improve the yield.
The joining is performed by a thread glue valve 18 that supplies a dot-on end face adhesive and a hot melt adhesive impregnated yarn supplied from a spot valve 16 arranged below the transport path from the upper surface of the transport path. An adhesive supply device 15 including a hot melt glue tank & pump 15a that melts the thermoplastic resin pellets and supplies them to the spot valve 16 and the thread glue valve 18 is provided.
The joined and continuous horizontal veneer is cut into a standard length by a standard clipper 20 and sent to a subsequent stage by a standard conveyor 22.

The loading mechanism D is deposited in the stacker 23 provided with the stacking table lifter 28 below. Sedimentation can be staggered stacking with staggered edges or aligned stacking with aligned edges.

[Dimensional veneer shaping mechanism B]
FIG. 2 is a diagram showing a detection state (a) of a veneer that detects a defective portion existing in a non-molded veneer in the sized veneer shaping mechanism B and cuts off the defective portion, and a sized veneer shaping mechanism (b). Is.
In the present invention, cutting control is performed leaving an acceptable defective portion. For example, the allowable width of the defective portion is set to the allowable width dmin, and if the defective portion in the middle portion and the measured defective portion width dn is smaller than this allowable width dmin, it is left as it is without being cut and is large. In that case, the width of the defective part after excision shall be excised so as to be less than the permissible width.
FIG. 2A shows two non-formed veneers 41a and 41b. The non-formed veneer 41a has irregular end faces in the front and rear, and a large hole in the middle portion due to large rot. A state with a large knot hole and a small knot hole is shown. The non-molded veneer 41b is shown to have two large and small cracks at the edge of the intermediate portion.
When the control of cutting the defective portion of the present invention is applied to the non-molded veneers 41a and 41b, the front and rear ends thereof are irregular, so that there are cutting portions c1, c6, c7 and c10. The defective portion in the middle portion is not excised for a nodal hole having a width of d4 smaller than the allowable width dmin of the allowable defective portion and a crack having a width of small d1.
This improves at least the stoppage of the length depending on the allowable width dmin remaining in the intermediate excision part. The permissible width dmin is determined by the quality of the plywood and the user's request.
Furthermore, if the defective width d5 due to large rot overlaps with the spot position of the end face joint, the cutting conditions are set by adding the condition of the position and shape of the defective part such as cutting large with c2 and c3 without leaving the defective part. can do.
For the width d4 of the large nodal hole, the cutting points c4 and c5 are determined so that the portion Δa + Δb remaining after excision is equal to or less than the allowable width dmin. Similarly, for the width d2 of the large crack, the cutting points c8 and c9 are determined so that the remaining portion Δc + Δd is equal to or less than the allowable width dmin.
When the excision width is dc, the excision control of the intermediate defective portion is determined as follows.
(1) dn ≤ dmin → As it is without disconnection.
(2) dn> dmin → dc = dn-dmin

FIG. 2B shows a transfer transfer system to the sized veneer shaping mechanism B and the subsequent horizontal peeling mechanism C.
The transport system 11 for the sized veneer shaping mechanism is formed so that the veneer is sandwiched and transported by endless chain conveyors arranged vertically on the transport path T of the veneer. It is formed by an upper chain conveyor 11a and a lower chain conveyor 11b. The transport system 11 for the sized veneer shaping mechanism includes a servomotor 4 with a carry-in drive reducer, and is intermittently driven.
From the entrance side of the transport system 11 for the sized veneer shaping mechanism, the entire surface detection 5 that detects the defective part by light transmission, the contact type thickness gauge 6 that detects the thin part of the veneer, and the sized clipper 7 are arranged. There is.
The data detected by the sensor, the transport system 11 for the sized veneer shaping mechanism, and the control device 32 for controlling the sized clipper 7 are arranged and controlled based on the detected data.

The full surface detection 5 is composed of a light receiver 5a arranged on the upper surface of the transport path T by irradiating light from a floodlight 5b arranged below the transport path T. The irradiated light passes through the defective portion of the veneer and receives light, so that the defective portion is detected. Light is irradiated to the entire width of the veneer, and if light is received over the entire width, that portion is recognized as the front and rear end faces of the non-formed veneer.
The thickness gauge 6 is configured by providing a reference roller 6d whose upper surface is located on the transport path T and a detection roller 6c which contacts the upper surface of the reference roller 6d at the tip of the thickness gauge arm 6b. The detection roller 6c sinks in a portion thinner than a predetermined thickness of the veneer and is amplified by the thickness gauge arm 6b, so that the thin portion can be detected.
The data detected by the full surface detection 5 and the thickness gauge 6 is sent to the control device 32, the cutting positions of the front and rear ends and the intermediate portion of the unmolded veneer are calculated, and the transport system 11 for the sized veneer shaping mechanism is set. The servomotor 4 with a carry-in drive reducer is intermittently driven to temporarily stop the non-formed veneer at the position of the sized clipper 7 and drive the movable blade 7a from the control device 32 to perform cutting.

[Horizontal peeling mechanism C]
The configuration of the horizontal peeling mechanism C is shown in FIGS. 3 to 10.
FIG. 3 is a sized clipper, FIG. 4 is a spot valve, FIGS. 5 to 8 are a thread glue valve, FIG. 9 is a glue tank, and FIG.

(Sized clipper)
A side view of the sized clipper 7 is shown in FIG. 3 (a), and a plan view is shown in FIG. 3 (b).
In the sized clipper 7 of the present invention, the fixed blade 7d is arranged below the transport path T, and the movable blade 7a is arranged above the fixed blade 7d. Stop and drop the movable blade 7a to cut.
The movable blade 7a is detachably attached to a movable blade base 7i attached below the knife holder 7b, which is a square shaft having a square cross section. The movable blade body 7c is adjusted and replaced as appropriate because the protrusion length of the blade is adjusted and wear or chipping occurs due to use.
In the present invention, the vertical surface of the movable blade base 7i is set along the side surface of the square knife holder 7b, and the other surface is set along the lower surface of the knife holder 7b. Since the corner of the movable blade base 7i is located at a position that substantially coincides with the lower end side of the square cross section of the knife holder 7b, and the lower surface of the knife holder 7b and one surface of the movable blade base 7i are in surface contact, stable mounting is possible. .. It is important that the lower surface of the knife holder 7b and the side surface on the movable blade side are formed in an orthogonal plane, and the shape of the other surface is arbitrary.
Since the movable blade body 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 body 7c has an elongated hole in the blade body. The movable blade guide 7f is applied to the upper surface of the movable blade body 7c, and the movable blade guide mounting bolt 7h is tightened. The rear end surface of the movable blade body 7c is pushed, and the adjustment is made with the movable blade push bolt 7e that adjusts the protrusion length of the blade.
The sized clipper 7 has a length for cutting over the entire length of the veneer, and has a long width as shown in the plan view 7 (b). The length is generally 140 to 350 cm, depending on the standard of plywood, and is divided into about two pieces so that it can be partially adjusted.

A cross section of the conventional sized clipper 170 is shown in FIG. 3 (c).
The conventional knife holder 170b has a circular cross section, the movable blade body 170c is set to be attached to the lower end of the circular knife holder 170b, and the movable blade base 170i is processed into a shape along an arc surface to form a movable blade. It is difficult to see the attached state of the body 170c hidden behind the knife holder 170b. Further, the bolt 170e for adjusting the protrusion length of the movable blade 170c penetrates the knife holder 170b and protrudes upward, and the adjustment is also difficult to see. Therefore, maintenance of the conventional sized clipper 170 requires skill.

(Spot valve)
FIG. 4 shows a spot valve 16 using a comb-shaped plate. (A) shows a plan view, (b) shows a comb-shaped plate, (c) shows a cross-sectional view, and (d) shows a state in which an adhesive adheres to the front end surface of a sized veneer.
The spot valve 16 is a device that supplies hot melt adhesive in dots from below the transport path of the veneer and attaches the adhesive to the front end surface of the moving veneer 31b.
In the illustrated example, a main body block 16c and a unit valve 16d are arranged below, a plate 16b having a recess formed by partially cutting is arranged above the main block 16c, and a large number of adhesive supply grooves 16e are formed in the recess. The shape plate 16a is attached.
The plate 16b has a tapered upper surface, and the adhesive supply groove 16e of the comb-shaped plate 16a is formed as desired at the uppermost portion.
The melted hot melt adhesive is supplied from the lower unit valve 16d to the adhesive supply groove 16e, and rises in dots on the transport path of the veneer. The state is shown in (d). The sized veneer 31b adheres the point-shaped end face adhesive 16f to the front end during transportation. The front end of the sized veneer 31b is guided by the tapered surface to scoop out the end surface adhesive 16f.
The rear end of the sized veneer 31b is temporarily stopped at a point past the spot valve 16 and is brought into contact with the tip of the sized veneer to be sent later to be joined.

As described above, the spot valve 16 is a mechanism for supplying the melted hot melt adhesive, and the comb-shaped plates 16a and 16b are heated to a high temperature. The adhesive supply groove 16e may be rubbed directly against the veneer, causing a problem of clogging due to wood powder or the like. The comb-shaped plate 16a can be removed from the plate 16b and scraped out from the open portion of the groove with a brush or the like. Regular cleaning can be done as easily as well.
The spot valve 16 of the present invention is divided into a plate 16b and a comb-shaped plate a provided with a large number of grooves, so that maintenance and the like can be easily performed in a short time.

FIG. 4 (e) shows an example of the conventional spot valve 160.
The conventional spot valve 160 is porous in which a main body block 160c and a unit valve 160d are arranged below and a plate 160b having an adhesive supply hole 160e formed above the main block 160c. A large number of small holes are provided at the top of one plate 160b, and the melted hot melt adhesive is supplied in dots from these holes.
Since it is a small hole, it is necessary to scrape it out one by one with a conical jig for trouble handling such as clogging and regular cleaning processing, and it is difficult to remove it when the adhesive hardens, so it is necessary to handle it at high temperature. It is a time-consuming and careful task.
In the spot valve 16 of the present invention, since the plate is divided and a large number of small grooves are formed along the sides, cleaning and the like can be performed easily and quickly, and maintenance can be performed safely without lowering the temperature of the high temperature member so much. You can restart quickly.

[Adhesive supply equipment]
FIG. 9 shows an example of the adhesive supply device 15 of the present invention. 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.
The adhesive supply device 15 is a device that heats and melts a pellet-shaped thermoplastic resin adhesive and supplies it as a liquid thermoplastic adhesive to a spot valve and a thread glue valve.
The adhesive supply device 15 includes a hot melt glue tank & pump 15a with 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 molten adhesive. It is provided with a spot valve supply pipe 15h and an adhesive supply pipe 15i for a hot-glue valve.

In the hot melt glue tank & pump 15a, block heaters 15g with a temperature sensor are arranged at the bottom and the center. In the present invention, the regenerative heater 15f is arranged on the peripheral surface of the hot melt glue tank & pump 15a.
The block heater generates heat using a normal power supply. The regenerative heater 15f generates heat by using the regenerative power of the servomotor used in the system for manufacturing the single horizontal strip.
In the illustrated example, the regenerative heaters 15f are arranged on both side surfaces and the back surface of the hot melt glue tank & pump 15a.
A pellet supply device vibrator 15d is provided in the pellet supply device 15b to supply pellets to the hot melt glue tank & pump 15a at any time.
The regenerative heater generates heat when the system is operating as an auxiliary heater, and in addition to auxiliary heating of the adhesive, uniform temperature distribution in the hot melt glue tank & pump 15a, energy saving and hot melt glue tank & pump It contributes to the miniaturization of 15a and the stabilization of the quality of the adhesive.

Block heaters generate strong heat and melt pellets, but the temperature near the heater is high and tends to be low near the heater. It is operating while holding it. In such a state, stagnation occurs in the corners of the tank, and non-fresh adhesive is used, such as remelting the solid adhesive that has been left unused. The quality of such adhesives deteriorates and causes troubles.
In the present invention, the regenerative power is used to heat the area including the upper side surface of the glue tank to the periphery that cannot be covered by the block heater during the operation of the system to make the molten state of the adhesive in the glue tank uniform. Can be kept.
Therefore, even if the glue tank is miniaturized, a sufficient amount of usable melt adhesive can be secured, and if the capacity of the glue tank is reduced, the block heater can also be miniaturized, and further energy saving can be achieved. The pellet feeder vibrator 15d is operated at any time to replenish the molten adhesive, which decreases with the miniaturization of the glue tank. It can be automatically replenished by providing a sensor or the like that detects a decrease in the liquid level. In the past, since the capacity was large, the frequency was such that the workers checked and replenished in batches before starting in the morning and before restarting in the afternoon.
Being able to miniaturize the high temperature glue tank is also useful for saving space and improving workability.

[Horizontal stripped veneer]
A plurality of small-width veneers 31b are joined to the end face and an adhesive impregnated thread is attached to the surface side to form a continuous piece of horizontal veneer, which is cut to a predetermined length to form a standard horizontal veneer. It is a veneer 31d.
An example of a standard length horizontal strip veneer 31d is shown in FIG.
In the illustrated example, five sized veneers 31b are joined together to form one horizontal veneer standard length veneer 31d. A large number of point-shaped end face adhesives 16f bonded by the spot valve 16 are present on the joint end face, and hot melt glue impregnated threads 17c formed in three rows on both sides and a central portion are present on the surface.

[Loading mechanism D]
The loading mechanism D of the present invention deposits the horizontal stripped veneer 31d formed in the previous step on the stacker 23 provided with the stacking table lifter 28. The deposited horizontal stripped veneer will be used for plywood manufacturing processes such as the plywood mechanism process.
An example of the stacker 23 used by the loading mechanism D of the present invention is shown in FIG.
The stacker 23 has a veneer transporting device 24 on the upper part and a stacking table lifter 28 on which a horizontal veneer single plate 31d is placed and deposited on the lower side. It consists of a braking device that drops the veneer.

FIG. 11A shows a front view of the stacker.
The veneer transfer device 24 for carrying the horizontal stripped fixed-length veneer 31d is the left and right stacker transfer conveyor left 24a and the stacker transfer conveyor right 24b mounted on the upper part of the gantry frame, and downward facing these conveyors. It is equipped with a stacker gate left 24c and a stacker gate right 24d arranged in.
The braking device includes stacker gates 24c and 24d, a gate opening / closing cylinder 25, a kicking device 26, and a matching device 27, and these devices are axially mounted and provided on the left and right sides.
The table lifter 28 is provided with a mechanism for lowering the table surface as the number of deposited sheets increases so that the distance at which the veneer falls can be kept constant. This is commonly used as a veneer table lifter.

The horizontal stripped standard single plate 31d cut to a fixed length in the previous process is sandwiched between the left and right stacker gates 24c and 24d and the left and right stacker transport conveyors 24a and 24b, and is sandwiched between the left and right stacker transport conveyors 24a. , 24b is operated, slid on the left and right stacker gates 24c and 24d, and waits on the deposit table lifter 28.
The left and right stacker gates 24c and 24d are expanded and contracted by the rod to which the gate opening / closing cylinder 25 is attached, and the horizontal stripped veneer 31d held by the stacker gates 24c and 24d is dropped onto the stacking table lifter 28. Veneer guides 27c and 27d are arranged on the side of the lifter to guide the falling veneer so that the veneer can be stacked in a regulated manner. The side surface of the horizontal veneer standard length veneer 31d that has fallen along the left and right veneer guides 27c and 27d is tapped with the left and right matching devices 27a and 27b having left and right mallets 27e and 27f to determine the deposition position of the veneer. Fix it. The left and right stacker gates 24c and 24d can be opened and closed differentially or simultaneously.
When the left and right stacker gates 24c and 24d are opened and closed differentially, the posture of the veneer is tilted toward the side that was opened earlier and falls, so the falling speed is fast and the veneer deposits in a biased state. If the differential is performed alternately on the left and right, the offsets are also alternated, and the shifting can be easily performed. On the other hand, when they are released at the same time, the air layer on the lower surface of the veneer becomes a resistance, and it takes time to deposit. Although it may fluctuate slightly from side to side, it is suitable for aligned stacking because the sides of the deposited veneer are basically aligned.

(Alternate opening operation)
FIG. 11B shows a process in which the left and right stacker gates 24c and 24d are alternately opened to stack the stacks.
1. 1. The horizontal stripped fixed-length veneer 31d is conveyed by the stacker transfer conveyor left 24a and the stacker transfer conveyor right 24b, and is stopped above the existing standard-length veneer 31e on the stacking table lifter 28.
2. In the case of slipping to the right side, the stacker gate right 24d is opened, and the right side of the horizontal stripped veneer 31d starts to fall with the stacker gate left 24c as a fulcrum.
3. 3. When the stacker gate left 24c is opened and the left side of the horizontal stripping standard veneer 31d begins to fall, the kicking device left 26a kicks the horizontal stripping standard veneer 31d to the right so as to hit the single plate guide right 27d. ..
4. After the horizontal stripped veneer 31d falls, the stacker gate left 24c and the stacker gate right 24d are closed, and the kicking device left 26a is returned to the fixed position.
5. The matching device left 27a and the matching device right 27b are closed to align the horizontal stripped veneer 31d to a predetermined position. The distance between the left and right aligning devices is basically the length obtained by adding the left and right shifts to the width dimension of the standard veneer.
6. After aligning the horizontal stripped veneer 31d, the matching device left 27a and the matching device right 27b are opened in the standby position.
Then, in the case of Zuras on the left side, the operation symmetrical to the above is performed.
If the above right-sliding and left-sliding are repeated one by one and piled up, they will be piled up.

(Simultaneous opening operation)
FIG. 11C shows a process in which the left and right stacker gates 24c and 24d are opened at the same time for aligned stacking.
1. 1. The horizontal stripped standard veneer 31d is conveyed by the conveyor left 24a and the conveyor right 24b, and stopped above the existing standard veneer 31e.
2. The stacker gate left 24c and the stacker gate right 24d are opened at the same time, and the horizontal stripped veneer 31d is dropped and deposited.
3. 3. After the horizontal stripped veneer 31d has fallen, the matching device left 27a and the matching device right 27b are operated to align the existing standard veneer 31e so that the side ends are aligned, and after the alignment is completed, the alignment is set to a fixed position. Open and wait for the next action. The alignment intervals of the left and right matching devices 27a and 27b are set to be substantially the same as the dimensions of the standard-sized veneers, and the side portions of the stacked standard-sized veneers are aligned.
The left and right kicking devices 26a and 26b are not used when the stacking is not performed.
