Description

  TECHNICAL FIELD The present invention relates to a horizontal raw veneer that is an intermediate product in the manufacture of plywood, and a method and apparatus for manufacturing the same.

Wood-based plywood is manufactured by laminating veneers cut thinly from logs. Logs are not true cylinders, and because there are defective parts such as cracks and rotting joints, they are used as fixed-size single boards by gathering together small veneers from which the defective parts have been removed. In addition, log cutting is performed in a high moisture content state, and a dry veneer is used for plywood lamination, so a drying process is required. A veneer cut from a log and having a high water content is called a raw veneer.
Before putting the cut raw veneer into the dryer and drying it, cut off the defective parts to reduce the load on the dryer and improve the handleability and connect them together to form a fixed length horizontal veneer veneer Has been done. Since raw veneer is difficult to bond due to its high water content, various proposals are available, including not only bonding with adhesive alone, but also using adhesive and bonding yarn, embedding yarn in shallow grooves, and using adhesive tape. Has been.
Furthermore, since it is necessary to excise newly generated defective parts such as blows and tears in the drying process, it is inappropriate to use a material that obstructs the cutting blade as a transverse material. Other than metal, a string that is difficult to cut is also inappropriate. This also has an adverse effect on the machinability of the plywood that is a product, and it is inappropriate that foreign materials are mixed in when it is recycled into chips.
Here are some examples of conventional horizontal strips.

  In Patent Document 1 (Japanese Utility Model Publication No. 58-45048), as such a transverse veneer, a plurality of raw veneers arranged densely in a continuous manner in a direction perpendicular to the fiber direction are arranged in the arrangement direction. It has been proposed to dry in a thin band shape and attach a bonding yarn coated with a hot melt adhesive to the dried portion and fix it.

In Patent Document 2 (Japanese Patent Publication No. 60-47082), the spliced yarn is a yarn spun from a synthetic resin having a melting temperature lower than the drying temperature of the dryer, and the adhesive melts the spliced yarn. A thing using what consists of pastes, such as a synthetic resin with a melting temperature lower than temperature, is also proposed.
That is, this prior art is a proposal related to the present applicant, and since this disclosed technique is the basis, it will be described in detail.
In the invention according to Patent Document 2, a bonded yarn having a melting temperature lower than the drying temperature of the dryer on the surface of an undried small width veneer containing a large amount of moisture is further higher than the melting temperature of the bonded yarn. The adhesive yarn having a low melting temperature is adhered to the bonding yarn and the adhesive yarn at the final stage of the subsequent drying process and melted by the single plate material temperature that has reached the drying temperature, so that the bonded state can be released. As an intermediate product, it is related to the horizontal raw veneer.
Conventionally, a horizontal raw veneer as this kind of intermediate product (see, for example, JP-A-55-132201), when dried in a subsequent drying step, individual narrow raw veneers cause dry cracks in the drying process, Material defects such as missing joints and material weak parts, or distorted cutting edges due to uneven drying shrinkage and gaps in mutual abutting parts occur, so it was necessary to repair them again. However, in the re-repairing work, even if the binding yarn remaining on the surface of the veneer is crushed and applied again to a dry veneer crossing machine etc., the veneer breaks. However, there is a serious inconvenience that the splicing yarn is not cut and therefore the chips to be removed cannot be substantially removed. The invention according to Patent Document 2 is inserted into a dryer by first joining individual narrow width veneers after fully grasping the phenomenon of material defects after drying unique to the above horizontal veneer veneers. Connecting and disconnecting as an intermediate product that can significantly improve workability and filling efficiency, and finally eliminate the adverse effect on the transverse work for subsequent repair by releasing the connection. The present invention is intended to provide a new horizontal veneer veneer that can take the two aspects described above.
A specific example will be described with reference to FIG. In a transverse raw veneer 4 in which a large number of narrow raw veneers 1 are continuously arranged in a direction perpendicular to the fiber direction, and a plurality of rows of connecting yarns 2 are adhered by an adhesive 3 in the arrangement direction. The splicing yarn 2 is made of a yarn spun from a synthetic resin having a melting temperature sufficiently lower than the drying temperature of the dryer, for example, about 180 ° C., such as polypropylene that can be melted at about 100 to 120 ° C. A spliced spliced yarn 2 is used, and the adhesive 3 is a paste such as a synthetic resin having a melting temperature sufficiently lower than the melting temperature of the spliced yarn 2, for example, melted at 60 to 80 ° C. With the horizontal adhesive veneer 4 as an intermediate product that can be connected to the adhesive 3 at the beginning using the adhesive 3 made of a paste such as ethylene vinyl acetate copolymer resin (EVA) is there. Further, in the state of releasing the connection of the horizontal raw veneer 4, the connecting yarn 2 and the adhesive 3 are gradually melted by the temperature of the single plate material that has reached the drying temperature in the dryer furnace by the drying operation by the dryer in the subsequent step. Therefore, since the initial connection state is gradually released and returned to the individual small-width dry veneer 6 again, it is supplied to the repair process in the subsequent stage. The adhesive 3 functions only to improve the insertion workability and the filling efficiency when the narrow width veneer 1 is first inserted into the dryer.
In addition, the individual narrow width veneer 1 constituting the horizontal raw veneer 4 as an intermediate product shown in the figure is a rough cut veneer cut by leaving some defective portions 5 at the front and rear, which is usually This may be constituted by a positive-cut single plate that is cut without leaving any defective portion 5 of.

Patent Document 3 (Japanese Patent Application Laid-Open No. 2003-291105) discloses a joining apparatus for a small-width single plate using an adhesive tape having a complicated mechanism.
In Patent Document 4 (Japanese Patent Application Laid-Open No. 2001-232603), a veneer single plate is cut into a sizing width, end faces of each other are joined to form a continuous belt-like single plate, and then cut into predetermined dimensions. A veneer veneer horizontal crossing method for obtaining a horizontal veneer of a method, a first horizontal crossing step of obtaining a pile of a horizontal veneer of a first standard size by joining, cutting and stacking at a normal standard size, A single sheet 3 of the first standard size obtained in the first horizontal crossing step is fed out from the piles one by one, and the end faces thereof are joined together with an adhesive, and a second fixed number that is a multiple of the first standard size. A veneer veneer cross-crossing method is disclosed which comprises a second cross-step process for obtaining a pile of transverse cross-cut veneers of a scale size.

  In Patent Document 5 (Japanese Patent Application Laid-Open No. 62-156902), an adhesive such as a molten hot melt resin is applied to the front edge of a transverse veneer, particularly a small veneer veneer, which is handled in the field of plywood production. While pushing the subsequent veneer veneer that has been applied to the rear edge of the preceding veneer veneer, it is pushed back together, and the surface is glued with adhesive yarn impregnated with molten hot melt resin etc. An extrusion braking method and apparatus at the time of edge collision in an extrusion-type single plate crossing machine configured so as to obtain a transverse single plate continuous in a shape are disclosed.

  Patent Document 6 (Japanese Patent Application Laid-Open No. 8-216105) discloses a gluing mechanism by injection of a bead-like molten hot melt resin from a space by a gluing nozzle 9 installed in a diagonally upper space of a single plate joint portion; A cold pressure device with a cutting glue comprising a cold pressure mechanism for spotting molten hot melt resin from directly above a single plate joint by a pressure cooling bar provided on both sides of the movable knife side of the cutting knife 7 so as to be lifted and lowered and opened and closed is provided. A cold pressure device with cutting glue in a single plate bonding machine applied to a plate bonding machine is disclosed.

Since it is difficult to join raw veneer with a high water content, it is difficult to use a special adhesive, partially dry the adhesive joint, or cure the adhesive. It is necessary to heat. Adhesive preparation, storage, and usable time are limited, and there is much room for resolution in terms of efficiency, workability, and cost. If the adhesive thread and the tape with the adhesive also have the same problems as the adhesive, it is necessary to prepare the thread and the tape.
The method of embedding a thread in a shallow notch provided in the longitudinal direction requires precise control of the notch blade to make a notch in a thin single plate of about 1 to 4 mm, and problems such as pulling out easily occur. Problems may also arise in efficiency and post processing of the yarn.
Furthermore, in recent years, conifers such as cedar, pine, karamatsu, and spruce, which are small-diameter trees, are often used as raw wood. First, the generation of single plates that are uneven and have many defective portions increases. Since such single plate processing is often a bottleneck, there is a need for the development of efficient processing means.

  In view of such conventional technology, an object of the present invention is to provide a horizontal raw veneer that can securely and firmly bond raw veneers and has little influence on the post-process after drying. Moreover, this invention makes it a subject to provide the manufacturing method and its apparatus which can simplify the manufacturing process and manufacturing apparatus of a transverse raw veneer, and can produce efficiently.

  As a result of diligent examination of the raw veneer veneer, the present invention uses a synthetic resin staple to bond the green veneer, and is securely and firmly bonded without causing poor bonding, simplifying the process and producing The present inventors have found that the speed is improved, the cost is reduced, and the processing after drying is facilitated, and the present invention has been achieved.

The gist of the present invention is as follows.

It has a transverse crossing step in which it is densely arranged in the orthogonal direction and connected with an H-shaped synthetic resin staple so as to straddle the contact end surface with the adjacent narrow width veneer. A method for producing a horizontal veneer veneer.
(5) A narrow raw veneer forming means for cutting a defective raw material veneer in the fiber direction to form a narrow raw veneer, and the raw veneer obtained in the narrow raw veneer forming step Are arranged in a dense manner in a direction perpendicular to the fiber direction, and are connected by an H-shaped synthetic resin staple so as to straddle the contact end surface with the adjacent raw veneer, An apparatus for producing a transverse raw veneer, comprising: a regular cutting means for cutting the strip-like transverse raw veneer obtained in the transverse peeling step into a predetermined length.

Therefore, the apparatus can be simplified.

Hereinafter, the present invention will be described in detail based on the embodiments of FIGS.
FIG. 1 is a perspective view of a horizontal raw single plate according to the present embodiment, FIG. 2 is a perspective view of a horizontal raw single plate in which a part of FIG. 1 is enlarged, and FIG. FIG. 4 is a side view of the horizontal raw veneer manufacturing apparatus of Example 1, and FIG. It is a side view.

As shown in FIG. 1, the horizontal raw veneer 10 of the present embodiment has a large number of small width veneers 11 arranged densely in a continuous manner in a direction orthogonal to the fiber direction. The plates 11 are connected by synthetic resin staples 12 so as to straddle the contact end surfaces 11 a of the adjacent narrow width single plates 11, 11. In the present embodiment, the staples 12 are driven in three places on both sides and the center along the contact end face 11a, but the number may be increased or decreased according to the material, length, etc. of the narrow width veneer 11. . Since the arrangement in the fiber direction of the narrow width veneer is the same as that in the conventional example of FIG.
As shown in FIG. 2, the synthetic resin staple 12 has an H-shape, and each tip has an engaging portion 12a that opens in a T-shape or L-shape on the back surface when driven. The effect is demonstrated and the connection is strengthened.
Numerous methods have been developed and put into practical use for forming such a narrow raw veneer by cutting out the defective portion of the raw raw veneer. For example, a defective part is cut by operating a knife on an anvil roll while transporting an endless veneer cut with a veneer lace disclosed in Japanese Patent Application Laid-Open No. 62-59003, and a subsequent divider. Sorted. Further, as a mechanism for separating and cutting, a two-blade configuration (see Japanese Patent Application Laid-Open No. 62-46601) in which blades are arranged at the top and bottom to perform cutting and disposal at the same time can be employed.

In the above-described embodiment, the positive-cut small-width single plate 11 having no defect on both sides is used. However, as shown in FIG. A horizontal raw veneer 20 using the plate 21 may be used. When such a rough cut small width veneer 21 is used, the defective portion may be repaired at the same time as the repair of the material defect generated in the drying process.
<Raw material veneer>
Among raw veneers with high moisture content that have been cut to a thickness of about 1 to 5 mm from raw wood logs, which are the raw materials for wood-based plywood, those that are less than standard and have defective parts such as rot, cracks, and nodes Raw veneer is the target. Such defective parts often occur from the first part of the log cutting operation. In particular, coniferous logs obtained from artificial forests such as Japanese cedar, pine, and karamatsu are often small-diameter trees, and a large number of logs are used.

<Staple>
The staple is formed from a thin thin wire made of a flexible synthetic resin having an H shape (see FIG. 6). In the storage state, it can be continuously wound in the shape of a rope ladder. When used, cut into an H-shape and penetrate a hollow perforated needle through a small green veneer, push the H-shaped staple through the inside of the perforated needle, and release the engaging part on the back of the veneer to prevent it from being removed. Narrow single plates to be connected to each other can be used as a horizontal veneer. Since it is in the shape of a rope ladder from the viewpoint of handleability, it becomes an H shape when separated individually. However, when prepared separately, it may be a shape that can be retained, and for example, the tip may be an L shape, a J shape, or the like.
With reference to FIG. 6, stapling will be described. FIG. 6A shows a state in which the ladder-like staple 15 is wound around the staple holder 16 and can be stored or loaded into the staple supply device. (B) shows a state in which the ladder-like staple 15 is cut into an H shape by a knife 33 in the stapler, and the cut H-shaped staple 12 has a T-shape that becomes the engaging portion 14 as shown in (c). It will be comprised from the front-end | tip part and the connection part 13. FIG. This H-shaped staple is flexible and shows a state in which it functions as a joining member by maintaining a bent posture driven into a single plate. There are staple connecting portions 13 so as to straddle the joining end surfaces 11a of the narrow width veneers 11, and the T-shaped engaging portions 14 are opened through the edges of the respective veneers so that they are prevented from being removed. The horizontal strip is completed.
The material is preferably a flexible and flexible synthetic resin wire. The flexibility of the staple is necessary to the extent that it can cope with the bending and pushing operation by the stapler. As the synthetic resin, either thermoplastic or thermosetting can be used, but a thermoplastic resin is generally used. In the case of staples having a melting point lower than that of the dryer, a thermoplastic resin is used. Further, it can be selected in consideration of the subsequent machinability.
Examples of the thermoplastic resin include polypropylene, ethylene vinyl acetate copolymer resin (EVA), polyethylene, and polyester that can be melted at about 100 to 120 ° C. as a material having a lower melting point than the heating temperature of the dryer. Polypropylene, EVA, polyethylene, polyester, and the like can be prevented from being melted even by the heat of the dryer by increasing the melting point. When a biodegradable resin (biodegradable polyester resin (Japanese Patent No. 2709234)) is used, waste treatment is easy.

<Stapler>
In the stapler, staples made of synthetic resin are driven into the edges of the front and rear small width veneers at the joining end surfaces of adjacent narrow width veneers.
An outline is shown in FIG. The basic structure is that two hollow perforated needles 31, 31 are passed through two adjacent narrow width single plates 11, 11, and the legs of the H-shaped synthetic resin staple 12 are passed through the hollow needles. Pushing to the back side of the plate, releasing and opening the T-shaped leg part becomes the retaining (engagement part 14), and the adjacent narrow width single plates are connected to each other to complete the transverse state.
The hollow perforated needle 31 is formed with a slit 35 continuous in the length direction on the surface side where the two needles face each other. The slit 35 is provided to allow the connecting member 13 of the H-shaped staple 12 to pass therethrough. Ladder-like ladder staples are introduced into the hollow perforated needle 31 from the obliquely front side according to the guide member. A knife gap 34 through which the knife 33 can enter is provided on the upper side of the hollow needle. When the ladder staple 15 is inserted into the upper portion of the hollow portion 36 of the perforating needle, the knife 33 enters from the knife gap 34 and is cut and separated into individual H-shaped staples 12. In addition, a pressure 32 that can move up and down the hollow portion 36 of the perforating needle 31 is disposed. In the state where the perforated needle 31 penetrates the narrow width veneer 11, the H-shaped staple 12 is bent and penetrates the narrow width veneer by the pressure 32 that moves up and down in the hollow portion 36, and the leg is formed on the back side. The part is opened from the tip of the hollow part 36 and is opened in a T-shape to form the retaining engagement part 14, thereby completing the horizontal stripping.
