The transport device for removing the wooden material pieces stacked on the call board at the front end portion or the rear end portion of the wooden laminated mat that is carried while being protected by side guides on both side surfaces thereof, and the wooden material pieces are removed. The present invention relates to a method of transporting a wooden laminated mat into a mold of a compression molding apparatus in a state, and a method of manufacturing a wood-based composite material by placing a molding mold in a place where a piece of wooden material is removed and compressing or heating with a compression molding apparatus. .

  As a method for obtaining a wood-based composite material, for example, a fixed-size material in which arrayed lignocellulosic fibers are fixed with an adhesive, and the lignocellulosic fibers are about 6 inches (about 15 cm) to about 4 feet (about 122 cm). ), A width of about 0.05 inch (about 0.1 cm) to about 0.25 inch (about 0.6 cm), and a length of about 0.05 inch (about 0.1 cm) to about 0.5 inch ( A thickness of about 1.3 cm), and the strength of the obtained sizing material is equal to or higher than the strength of at least one grade of lumber cut and sampled from the above-mentioned lignocellulosic fiber There has been proposed the above-mentioned sizing material characterized by having the resin solid content of the adhesive and the density of the obtained sizing material (for example, see Patent Document 1).

  Moreover, it is a plate-like product, the plate-like product has a thickness of 25 mm or more, is cut out from a single-layer panel made of a wood wafer, the wafer is aligned in a certain length direction, When the wafer is measured in the longitudinal direction in the large plane of the single-layer panel, the average deviation with respect to the major axis of the panel is in the range of 0 to 10 degrees, orthogonal to the large plane and in the longitudinal direction of the panel The average deviation when the wafer is measured in the length direction within a small plane is within a range of 0 to 5 degrees, and the wafer has an average length of 200 mm or more when measured in the grain direction of the wafer. The shaped product forms a width portion of the plate-like product by a pair of cut surfaces separated by a predetermined distance, and the cut surface is substantially parallel to the long axis of the single-layer panel from which the plate-like product is cut out. Wafer board plate products are known That (for example, see Patent Document 2.).

  The fixed-dimension material described in Patent Document 1 and the plate-shaped product described in Patent Document 2 are all arranged in the length direction of the cellulose fiber or the elongated wooden wafer along the length direction of the product, and bonded as necessary. It is obtained by mixing and laminating agents and orienting and laminating them in a mat shape, and then compressing or heating them, and can be applied as a wood-based structural material because of its high strength.

When obtaining a high-strength wood-based structural material such as a fixed-size material as in Patent Document 1 or a plate-like product as in Patent Document 2, an elongated wooden material can be obtained regardless of the shape of the product. A binder is mixed in the piece, and the length direction is aligned so that it becomes a long plate shape with a substantially rectangular cross-section to form a wooden laminated mat. This wooden laminated mat is placed on a call board, and the call board is conveyed. If it is necessary to place it on the equipment, it is transported to the stock yard while protecting both side surfaces with side guides, taken out from the stock yard and measured for its weight, or moved to a compression / heating compression molding equipment. A general method of obtaining a molded body by compression or heating is employed.

  However, when the lengthwise direction of elongated wood pieces are arranged along the length direction of a product and this is compression-molded to produce a wood-based composite material having a desired thickness, generally, Each step is required to transport the wood laminate mat to the compression molding device, transfer it onto the pressure plate of the compression molding device, place the molding die at a predetermined position around the wood laminate mat, and compress or heat. is there.

  The wooden pieces are roughly aligned in the length direction and stacked on a call board to form a wooden laminated mat. When transporting this to a compression molding device, the left and right and up and down vibrations, vibrations, etc. of the conveyor device such as a conveyor during transportation Thereby, the chip | tip of the both-sides edge part of the product length direction of a wooden laminated mat collapses, and a wooden material piece is scattered on a call board. In this case, if there is a piece of wooden material under the molding die placed at a predetermined position around the wooden laminated mat conveyed in the compression molding apparatus, a gap will be formed under the die, and compression or heating will be performed. In other words, the compressive force or heat is not evenly applied or insufficient, resulting in insufficient or uneven strength of the resulting wood-based composite material.

  In addition, in order to solve the above problem, after transferring the wooden laminated mat onto the pressure plate of the molding apparatus, and removing the wooden material pieces scattered on the call board around the wooden laminated mat, the wooden material piece removing tool and the wooden laminated material are removed. The wood laminate mat is greatly collapsed or the orientation is disturbed by contact with the mat. Therefore, in order to reliably remove the wood pieces around the wood laminate mat on which the molding die is to be placed, it is necessary to widen the range in which the wood pieces are removed. If it is removed and the molding die is arranged, the compression force or heat is not evenly applied or insufficient at the time of compression or heating, which causes a problem.

  In the present invention, when a wood-based composite material is manufactured by compressing or heating with a compression molding apparatus, long and narrow wooden material pieces mixed with a binder are substantially aligned in the length direction and stacked to form a wooden laminated mat.

It is a wood composite material conveying apparatus according to the first aspect of the invention.

  The method for transporting a wood laminate mat according to claim 3 (invention 3) comprises transporting a wood laminate mat in which elongated wood pieces mixed with a binder are substantially aligned in the length direction with an orientation laminate device to a compression molding device. A method for transporting wood laminated mats, wherein a pair of flat side guides is set up above a call plate that moves on a transport device, and a long wooden strip mixed with a binder between them is lengthened. Laminated wooden laminate mats that are stacked approximately in the same direction, and laminated on the front or rear in the length direction of the wooden laminate mat on the surface of the call board with both side surfaces of the wooden laminate mat in contact with the side guides The wood material piece is removed, and the wood laminate mat is conveyed into the molding die of the compression molding apparatus in a state where the wood material piece is removed.

  A method for producing a wood-based composite material according to claim 4 (invention 4) is a compression molding apparatus comprising a wood laminate mat in which elongated wood pieces mixed with a binder are substantially aligned in the length direction by an orientation laminate device. A method of manufacturing a wood-based composite material to be compressed or heated, comprising a pair of flat plate side guide pairs above a coal plate moving on a conveying device, and a long and narrow wood material mixed with a binder therebetween. Place the wooden laminated mat with the pieces roughly stacked in the length direction, and place the wooden laminated mat in the longitudinal direction on the side of the call board in the state where both sides of the wooden laminated mat are in contact with the side guide. Remove the wooden piece that is laminated to the mold, transport the wooden laminated mat into the molding die of the compression molding device with the wooden piece removed, and place the molding die at the position where the wooden piece is removed. The front and back frames are placed and compression molded In compressed or heated, characterized in that the production of wood composite materials.

  The method for producing a wood-based composite material according to claim 5 (invention 5) is a compression molding apparatus comprising a wood laminate mat in which elongated wood pieces mixed with a binder are substantially aligned in the length direction with an orientation laminate device. A method of manufacturing a wood-based composite material to be compressed or heated, comprising a pair of flat plate side guide pairs above a coal plate moving on a conveying device, and a long and narrow wood material mixed with a binder therebetween. Place a wooden laminated mat with the pieces roughly aligned in the length direction, and load the call board with the wooden laminated mat between the side frames of the molding die of the compression molding machine. While in contact with the guide, remove the piece of wood laminated on the front or rear in the length direction of the wood laminated mat on the surface of the call board, and place the molding die at the position where the wood piece is removed. Place the front and rear frames and press with a compression molding device. Or heated, characterized in that the production of wood composite materials.

  When manufacturing a wood-based composite material by stacking thin wood pieces mixed with a binder in the length direction and stacking them into a wood laminate mat and compressing or heating them with a compression molding device, Remove the wood pieces laminated on the front or rear end of the wood laminate mat conveyed while protecting both sides with side guides, and place the molding die at the place where the wood pieces were removed. A wood-based composite material is produced by compression or heating with a stationary compression molding apparatus.

  Since both side surfaces of the wood laminate mat are in contact with the side guides and the like to protect the orientation state and the laminate state of the wood laminate mat being conveyed, the wood material pieces are oriented between the side guides to form a mat. During stacking, the wood pieces are not scattered during the transportation of the wood laminate mat. However, there are pieces of wood material stacked in a mat shape at the front end or rear end of the call board, and when placing the mold around the wood laminate mat in the molding die, A piece of wood is sandwiched between the two to create a gap. For this reason, before or after transporting the wood laminate mat into the molding die, the wood material pieces of the front end portion or the rear end portion of the wood laminate mat are removed.

  As a method of removing the wooden piece, generally, a rotating roll brush or the like is applied to the front end portion or the rear end portion of the wooden laminated mat laminated on the call board, and the roll brush is rotated to turn the wooden piece. Is done. However, the wood material pieces at the front end or the rear end of the wood mat laminated on the call board can be removed by the roll brush, but the periphery of the wood laminate mat contacted by the roll brush causes some collapse by the rotating roll brush. . In particular, the corners of both sides of the mat are apt to collapse, this part is rounded and the material tends to be insufficient, and there is a problem that the product quality is not stable due to insufficient pressure, heating or nest during compression or heating. May occur.

  In the transport device for the wood laminate mat of the first aspect, the wood material piece removing tool is disposed at the front end portion and the rear end portion of the side guide in order to ensure the sealing property of the molding die of the molding device with a press. Then, when removing the wood pieces that are laminated on the front and back of the wood laminate mat in the length direction on the surface of the wood laminate while the wood laminate mat is being transported, both sides of the wood laminate mat serve as side guides. It removes using the said wood material piece removal tool in the state which is contacting.

  If you try to remove the laminated wood pieces without providing side guides, the corners on both sides around the removed wood mat will collapse, causing the orientation and lamination state of the wood laminate mat to be disturbed, By removing the wood material pieces with both sides of the wood laminate mat in contact with the side guides, the corners on both sides around the wood mat to be removed will not be broken and will not be chipped or rounded. The piece can be removed. Accordingly, it is possible to remove the laminated wood pieces while maintaining the orientation state and the laminated state of the wood laminate mat.

  Furthermore, if the wooden material piece removing tool is detached from the front end portion or the rear end portion of the wooden laminated mat after removing the wooden material piece, the wooden material piece removing device does not interfere with the compression or heating operation during press molding.

  The wood material piece removing tool is not particularly limited as long as it is a structure that can reliably remove the wood material piece laminated on the call board. For example, a roll brush, a reciprocating brush, a comb-like body having comb-like protrusions, a high-pressure air blowing nozzle, an air suction nozzle, or a pressure plate that is removed by shifting.

  In the case of a roll brush, the shape is not particularly limited, and a general shape, in which the hair of the roll brush is provided radially or spirally from the rotation axis, is used. The surface length of the roll brush is set to be slightly shorter than the facing width between the side guides when the wood material piece is paid out inside the side guides on the call plate, thereby preventing interference with the side guides. When the rotation axis is provided above the side guide, the diameter of the roll brush is set to about 2 to 3 times that of the side guide, and the roll brush is rotated above the side guide.

  At this time, if problems such as a large roll brush diameter and a heavy weight occur, the roll brush is rotated by reducing the roll brush diameter and placing the rotation shaft between the side guides. Ingenuity is done. Also, move the upstream or downstream side guide while holding both side surfaces of the wood laminate mat with the side guides with the end of the call plate and the end of the side guide aligned, or both sides of the wood laminate mat The roll brush may be rotated by providing a rotating shaft of the roll brush at a position where it does not interfere with the side guide, for example, by moving the call plate and the side guide integrally while holding the surface.

  The material of the roll brush bristles is not particularly limited, and is appropriately selected in consideration of the weight of the roll brush, the elasticity of the bristles, the required length, and the like. In addition, there is a possibility that static electricity may occur due to the contact between the wooden piece with adhesive and the rotating roll brush bristles, causing an accident such as a fire. It is preferable to use a metal fiber or the like so that the charge can be removed. Alternatively, ionized air may be blown out to the contact portion with a corona discharge type static eliminator or the like.

  If the wooden piece removing tool is a reciprocating brush, the direction of reciprocating motion is made parallel to the call plate surface. The front end of the hair is brought into contact with the front or rear end of the wood laminate mat and wiped off.

  For high-pressure air blowing or air suction, an air blowing nozzle or a vacuum nozzle may be disposed in the vicinity of the call plate at the front end portion or the rear end portion of the wood laminate mat to blow or suck the wood piece.

  In the method of shifting while pressing the surface of the wooden laminated mat, the wooden material piece is removed by pressing the surface of the wooden material piece to be removed using a plate material such as rubber or resin having elasticity and shifting it as it is.

  The method of disposing the wooden material piece removing tool at the front end portion or the rear end portion of the wooden laminated mat, or removing it after the arrangement is not particularly limited, but after removing the wooden material piece, no matter which structure removing tool is used. Needless to say, the mold must be movable a distance as long as it can be placed at a predetermined position. There are no particular limitations on the method of moving, but the wood is attached to the base frame of the transfer device or compression molding device, such as a hydraulic cylinder, an air cylinder, or an arm attached via a moving power device such as a motor. The wood piece removing tool may be fixed, and the wood material piece fixing tool may be moved to the position of determination by the power unit. Alternatively, these may be performed manually.

  The method for transporting the wood laminate mat of the invention 3 is that the wood laminate pieces in the longitudinal direction of the wood laminate mat placed in advance on the surface of the call board are brought into contact with the side guides on both sides of the wood laminate mat. In this state, it is removed by a wooden piece removing tool and then conveyed into a molding die.

  Since the method for removing the wooden piece and the wooden piece removing tool used are the same as in the case of the invention 1, they will not be described again. The wood mat can be conveyed into the molding die while being placed on the call board in a state where there are no wood material pieces before and after the wood laminate mat.

  A method for producing a wood-based composite material according to a fourth aspect of the present invention is such that a wood material piece in a longitudinal direction of a wood laminate mat placed in advance on the surface of a call board is in contact with both side surfaces of the wood laminate mat on side guides. In this state, it is removed by a wooden piece removing tool and then conveyed into a molding die. The wood laminate mat is placed at a predetermined position in the molding die in a state where there is no wood material piece before and after the wood laminate mat.

  Also in this manufacturing method, the method of removing the wooden material piece and the wooden material piece removing tool used are the same as in the case of the invention 1, and therefore will not be described again. Immediately after placing the call board on which the wooden laminated mat is placed at a predetermined position of the molding die, the front frame and the rear frame of the molding die are placed and compression molding is performed. Therefore, since the pressure or heating is not insufficient or the nest is not formed during compression or heating, the quality of the obtained wood-based composite material is stabilized.

  In the method for producing a wood-based composite material according to the fifth aspect of the present invention, the wood laminate mat placed on the call board is conveyed to a predetermined position of the molding die, and at the position, both side surfaces of the wood laminate mat are side frames of the molding die. With the wood material piece removing tool in the longitudinal direction of the wood laminated mat placed on the surface of the call board in the state where it is in contact with the wood plate, it is removed.

  Also in this manufacturing method, the method of removing the wooden material piece and the wooden material piece removing tool used are the same as in the case of the invention 1, and therefore will not be described again. However, it goes without saying that the wood piece removal tool must be moved to a position completely removed from the mold before compression, and for this reason, the wood piece removal tool does not interfere with the compression operation. It is necessary to be able to move to.

  Compression molding can be performed by placing the front and rear frames of the mold in the absence of wood pieces before and after the wood laminate mat, and there is insufficient pressure, heating, or nest during compression or heating. As a result, the quality of the obtained wood-based composite material is stabilized.

  In the first aspect of the present invention, the wood material pieces laminated on the front and rear portions in the length direction of the wood laminate mat on the call board surface in a state in which both side surfaces of the wood laminate mat are in contact with the side guides. Since it removes with a piece removal tool, especially the orientation state and lamination | stacking state of the corner | angular part of the both sides | surfaces around the wooden laminated mat to be removed do not collapse. Further, since the wood material piece removing tool is detached from the front end portion or the rear end portion of the wood laminated mat after the wood material piece is removed, the wood material piece removing tool does not interfere with the next operation such as movement of the call board or the side guide.

  Accordingly, the wood material piece removing tool used is not particularly limited as long as it can reliably remove the wood material pieces laminated on the call board. For example, a roll brush, a reciprocating brush, a comb-like protrusion are used. A general method such as a comb-like body, high-pressure air blowing or air suction, or a method of shifting and removing the surface of the wood laminate mat can be used.

  In the invention 3, since the transport device for the wood laminate mat according to the invention 1 or 2 is used, the wood laminate mat on the call board is obtained in advance without breaking the orientation state and the laminate state of the front and rear ends of the wood laminate mat. The wood laminate mat can be conveyed into the molding die after removing the wood pieces laminated on the front and rear in the length direction.

  In invention 4, after removing the wooden material piece laminated | stacked on the surface of a call board in the state which the both sides | surfaces of the wooden laminated mat are contacting the side guide, it conveys to a shaping | molding metal mold | die, Since the front frame and the rear frame of the molding die are placed at the removed position, the wood-based composite material obtained by compression or heating with a compression molding apparatus becomes a product with stable quality.

  In invention 5, after transporting the wood laminate mat into the side frame of the molding die, the wood material piece laminated on the front end portion or the rear end portion of the wood laminate mat is removed, and the wood material piece is removed. Since the front frame and the rear frame of the molding die are placed at the positions, the wood-based composite material obtained by compression or heating with a compression molding apparatus becomes a product with stable quality.

  Next, the present invention will be described with reference to the drawings. FIG. 1 is an example in which the wooden piece removing tool is a roll brush, and the wooden piece of the front end portion or the rear end portion of the wooden laminated mat placed on the call board is removed, (a) is a front view, (b) ) Is a side view excluding the side guide. FIG. 2 is an example in which the wooden piece removing tool is a reciprocating brush, and the wooden piece of the front end portion or the rear end portion of the wooden laminated mat placed on the call board is removed, (a) is a front view, b) is a side view excluding the side guide. FIG. 3 shows an example in which the wooden piece removing tool is an air blowing nozzle or an air suction nozzle, and removes the wooden piece of the front end portion or the rear end portion of the wooden laminated mat placed on the call board, (a) The side view except a side guide, (b) is a perspective view of an example of an air blowing nozzle, (c) is a perspective view of an example of an air suction nozzle. FIG. 4 is an example in which the wood material piece removing tool is a comb-like body having comb-like projections, and the wood material pieces of the front end portion or the rear end portion of the wood laminated mat placed on the call board are removed. Is a front view, and (b) is a side view excluding a side guide. FIG. 5 shows a pressing plate for pressing the surface of the wooden laminated mat by the wooden piece removing tool. The pressing plate is pressed on the wooden laminated mat and shifted sideways, and the front end portion or the rear end of the wooden laminated mat placed on the call board It is an example which removes a wood material piece of a part, (a) is a front view, (b) is a side view except a side guide.

  In FIG. 1, a side guide 3 is placed on a call plate 2 that is transported on a transport device 1 by a belt conveyor, a chain conveyor, a live roller, and the like, and a wooden laminated mat 4 is stacked between the side guides 3. Yes. The roll brush 5 (wood material piece removing tool) is attached to a base frame (not shown) such as the conveying device 1 or a compression molding device via a power device or the like (not shown) for moving the roll brush 5. It is fixed to the arm 9 and is arranged at the front end or the rear end of the wood laminate mat 4.

  The width of the roll brush 5 is substantially the same as the width of the side guide 3. The bristles 5252 of the roll brush 5 are radially planted around the brush shaft 51. The length of the bristles 52, that is, the outer diameter of the roll brush is arbitrary, but if it is too large, the wood material pieces 41 near the front and rear ends of the wood laminate mat 4 may not be removed. In addition, if it is too small, there is a possibility that the wooden material pieces 41 laminated in a mat shape will be scraped out from the end face of the wooden laminated mat 4 and the wooden laminated mat will collapse, so that the size of the wooden material pieces 41 and the like are appropriately set. Should be determined in consideration of

  The shaft 51 of the roll brush 5 is arranged in parallel with the front and rear end portions of the wood laminate mat 4, and the shaft extends from the roll brush to drive a power device (not shown) such as a motor for rotating the roll brush 5. ) Is attached to form a rotating shaft 51. The rotation direction of the roll brush 5 is a direction in which the roll brush 5 sweeps the wooden block 41 from the wooden laminated mat 4 outward. Accordingly, the rotation directions of the roll brushes 51 and 52 are opposite to each other at the front and rear ends of the wood laminate mat 4.

  The roll brush 5 is arranged so that the rotary shaft 51 is slightly inside the end of the wood laminate mat 4 and the end of the wood laminate mat is in contact with the roll brush before the wood material piece 41 is removed. . When removing the wood material piece 41, when the roll brush 5 is rotated and rotated while the both side surfaces of the wood laminate mat 4 are in contact with the side guides 3, the both ends of the wood laminate mat 4 at the front and rear ends of the wood laminate mat 4 are removed. The wood material piece 41 is removed so as to be swept out by the rotating roll brush 5.

  FIG. 2 shows an example of a reciprocating brush in which the wood material piece removing tool is used. In the reciprocating brush 6, the side guide 3 is placed on the call plate 2 transported on the transport device 1, and the wood laminate mat 4 is stacked between the side guides 3. The reciprocating brush 6 (wood material piece removing tool) is a power frame for reciprocating or moving the reciprocating brush 6 on a base frame (not shown) such as the conveying device 1 or a compression molding device (not shown). The handle 61 is fixed to the arm 9 attached to the wood laminated mat 4 and disposed at the front end portion or the rear end portion of the wood laminate mat 4.

  In the reciprocating brush 6, bristles 62 are planted in one direction on the brush handle 61. The reciprocating brush 6 has the bristles 62 of the wood laminate mat 4 before the wood piece 41 is removed. It arrange | positions so that it may touch the front-and-rear both-ends part 41 or may be located in a little inside.

  When removing the wood material piece 41 with the reciprocating brush 6, first touch the reciprocating brush 6 with the front and rear ends of the wood laminate mat 4 while both end faces of the wood laminate mat 4 are in contact with the side guide 3. The hair 62 is lowered until the tip of the bristles touches the surface of the call board 2, moved on the call board 2 so as to sweep out the wood piece 41, lifted again and returned to the initial position, and again touched the wood laminate mat 4. The operation of sweeping down the wooden piece 41 is repeated.

  Therefore, the width of the reciprocating brush 6 is substantially the same as the width of the side guide 3. The length of the bristles 62 of the reciprocating brush 6 is arbitrary, but if it is too long, when the reciprocating brush 6 is lowered, the bristles 62 hit the front and rear ends of the wood laminate mat 4 and bend. There is a fear. On the other hand, if it is too small, if the call board 2 is bent or the like, the wood material piece 41 laminated in a mat shape may not be partially swept out during the sweeping operation. It may be determined in consideration of the size and the properties of the call board 2.

  FIG. 3 shows an example of a side guide for removing the wood material piece 41 at the front end portion or the rear end portion of the wood laminated mat 4 placed on the call board 2 in which the wood material piece removing tool is an air blowing nozzle or an air suction nozzle. FIG. In the case of air blowing, the blowing portion width of the air blowing nozzle 7 is substantially the same as the width of the wood laminate mat 4, but the blown air tends to spread on both sides, so it may be slightly smaller. Further, if the air ejection speed is too slow, the wood material piece 41 cannot be blown away, and if it is too fast, the wood material piece 41 laminated on the front and rear ends of the wood laminate mat 41 will be peeled off and the wood laminate will be peeled off. Since the mat 41 may be destroyed, the mat 41 may be appropriately determined in consideration of the laminated thickness of the wooden laminated mat 4 and the size of the wooden material pieces.

  When removing the wood material piece 41 by air blowing, the air blowing nozzle 7 is arranged above both front and rear ends of the wood laminate mat 4 and the direction of the jet is adjusted so that the blown air is slightly outward from the wood laminate mat 4 Is done. The air blowing nozzle 7 is lowered along both ends of the wood laminate mat 4 while blowing off the wood material pieces 41 at both front and rear ends of the wood laminate mat 4. Both ends of the wood laminate mat 4 are blown away by the blown air, and when the air blowing nozzle 7 is lowered to the vicinity of the coal plate 2, the wood material piece 41 is blown off completely and removed. In this state, the air blowing nozzle 7 is released.

  Air suction may be used alone, but when air is sucked, a wide range of air is sucked, so that both ends of the wood laminate mat 4 may be easily collapsed. Therefore, it is usually used in combination with air blowing.

  In this case, the air suction nozzle 8 may be a normal air suction nozzle as long as the wood material piece 41 blown off by the blown air is reliably sucked, and the size of the suction nozzle is the cross section of the wood laminate mat. It is sufficient if they are approximately the same. Although not shown, air suction may be used in combination with a roll brush 5 or a reciprocating brush 6 other than air blowing.

  FIG. 4 is a side view of an example in which the wood material piece removing tool is a comb-like body having comb-like protrusions, and the wood material piece 41 at the front end portion or the rear end portion of the wood laminated mat 4 placed on the call board 2 is removed. It is a side view except a guide. That is, in the comb-like body 10, the side guide 3 is placed on the call plate 2 transported on the transport device 1, and the wood laminate mat 4 is stacked between the side guides 3. The comb-like body 10 is attached to a base frame (not shown) such as the conveyance device 1 or a compression molding device via a power device or the like (not shown) for reciprocating or moving the comb-like body 10. The ridge 102 is fixed to the arm 9 and disposed at the front end portion or the rear end portion of the wood laminate mat 4.

  The comb-like body 10 has teeth 62 planted in one direction on the ridge 102, and the comb-like body 10 has the teeth 101 at the front and rear end portions 41 of the wood laminate mat 4 before the wood piece 41 is removed. It arrange | positions so that it may be located in a little inner side from a front-end part or a rear-end part.

  When removing the wood material piece 41 with the comb-like body 10, the comb-like body 10 is first placed in the state where both end surfaces of the wood-laminated mat 4 are in contact with the side guides 3, and the blade tip 101 is the front and back of the wood-laminated mat 4. Touch the upper surface slightly inside from both ends, lower until the tip of the tooth 101 touches the surface of the call board 2, move the call board 2 sideways to sweep out the wood piece 41, lift it up again and start Returning to the position, the wood laminate mat 4 is again touched and lowered, and the operation of sweeping out the wood piece 41 is repeated.

  Therefore, it is preferable that the tips of the teeth 101 of the comb-like body 10 are thinned so that the teeth 101 can be easily stuck in the wood laminate mat 4. The width of the comb-like body 10 is substantially the same as the width of the side guide 3. . Further, although it varies depending on the thickness of the individual teeth 101 in the width direction of the comb-like body 10 and the material of the teeth 101, it is usually about 1 mm to 10 mm, preferably about 1.5 mm to 5 mm, and usually about 3 mm is frequently used. The If it is larger than 10 mm, the teeth 101 may not pierce the wood laminate mat 4 when the comb-like body 4 is lowered, and if it is smaller than 1 mm, it may be bent when pierced.

  Further, the width of the teeth 101 in the thickness direction of the comb-like body 10 is not particularly limited as long as the teeth 101 are not bent in the removal work of the wood material piece 41. The length of the comb teeth 101 is arbitrary, but if it is too long, the comb teeth 101 may hit the front and rear ends of the wood laminate mat 4 and bend when the comb 10 is lowered.

  On the other hand, if it is too small, if the call board 2 is bent or the like, there is a fear that the wood material piece 41 laminated in a mat shape may be partially swept out during the sweeping operation, and one sweeping operation is performed. In this case, the wood material piece 41 cannot be completely removed, and the sweeping operation must be repeated several times. Therefore, the size of the wood material piece 41, the laminated thickness of the wood laminated mat 4 and the properties of the call board 2 are appropriately determined. It only has to be done.

  The interval between adjacent teeth 101 of the comb-like body varies depending on the size and shape of the wood material piece 41 and the lamination height and width of the wood laminate mat 4, but is usually about 20 mm to 50 mm. If it is smaller than 20 mm, the teeth 101 are unlikely to pierce the wooden laminated mat, and if it is larger than 50 mm, the teeth 101 may be moved sideways to sweep out the wooden piece 41 and the wooden piece 41 may remain on the call board.

  The material of the comb-like body 10 may be any material that is strong and difficult to bend, and examples thereof include metals such as stainless steel, iron, and aluminum, synthetic resins, and fiber-reinforced synthetic resins. In addition to the above, the building 102 may be a natural material such as wood. Further, the tooth 101 and the ridge 102 may be made of the same material or different materials.

  FIG. 5 shows a pressing plate for pressing the surface of the wood laminate mat by the wood piece removing tool. The front plate or the rear end of the wood laminate mat placed on the call board is pressed against the wood laminate mat and shifted laterally. It is a side view except the side guide of an example which removes the wood material piece of a part. The pressing plate 11 has a pressing surface 111 attached to the tip of the support bar 112.

  When removing the wooden piece 41 with the pressing plate 11, first the pressing plate 11 and its pressing surface 111 with the end portion of the wooden laminated mat 4 in contact with the side guide 3. 4. Place the front and rear ends of 4 to be the positions you want to remove, touch the upper surface of the wood laminate mat 4, lower the support bar 112, press the wood laminate mat 4 with the holding surface 111, and move sideways in the pressed state Then, the wood material piece 41 at the tip of the wood laminate mat 4 is removed.

  The length of the pressing surface 111 of the pressing plate 11 along the length direction of the wood laminate mat 4 is 30 mm or more, preferably 50 mm or more. If it is smaller than 30 mm, even if the upper surface of the wooden laminated mat 4 is pressed by the pressing surface 111, when the pressing plate 11 is moved sideways, the tip of the wooden laminated mat 4 does not move, and the wooden piece 41 is removed. There is a risk of not being able to. The width of the pressing surface 111 is the same as the width of the wood laminate mat 4.

  The material of the pressing surface is not particularly limited as long as the plate has high rigidity. However, if the material is highly elastic, when the pressing surface 111 is pressed against the upper surface of the wooden laminated mat 4 by the support rod 112, the material is deformed according to the unevenness of the surface of the wooden material piece 41 below the pressing surface 111, and the wooden material Since the piece 41 is pressed well, it is more preferable. For example, as an example, various metals, various synthetic resins, various fiber reinforced synthetic resins, inorganic materials such as concrete, hard rubber, natural materials such as wood, natural fibers, woven and non-woven fabrics such as synthetic resin fibers, the above And other materials. The same applies to the support rod 112.

  The surface in contact with the upper surface of the wood laminate mat 4 of the pressing surface 111 preferably has a large coefficient of friction with the wood material piece 41. Therefore, anti-slip processing may be applied to the above material.
