Description

In the present invention, a flat plate (a thin plate such as a veneer single plate) is conveyed while being displaced to an arbitrary posture. For example, the present invention relates to a plate conveying method and apparatus for reversing the front and back of a veneer single plate while changing the conveying height .

  In general, in a plywood factory, the veneer veneer may be transferred to the next processing step while the posture of the veneer veneer is displaced depending on the transfer mode to each processing apparatus. Usually, the log is cut into a standard length, both ends of the longitudinal direction are supported by a veneer lace, and the veneer veneer is rotated and cut by feeding the long blade and the edge to the outer surface of the log. A veneer veneer is cut continuously in a state where its fiber directions are orthogonal, and is wound up as it is on a take-up reel and temporarily stored as a wound ball on a reeling deck, or cut into a fixed length. Once deposited as a pile of mountains.

  Thereafter, the veneer veneer is dried in the drying step so that the finished moisture content is 8 to 12%. The veneer dryer used in this drying process is constructed by ending a pair of upper and lower chains, wire nets, etc. endlessly, or by arranging a set of upper and lower rolls in multiple rows in the transport direction. In general, the former veneer dryer is used to dry a continuous veneer veneer unwound from a roll, and the latter veneer dryer is cut to any predetermined width such as 2, 3, 4 ... The rectangular veneer veneer or the irregular veneer that is less than a predetermined width is conveyed with its fiber direction parallel to the conveying direction.

  The veneer veneer is initially conveyed on the belt conveyor adjacent to each other at a certain interval with the fiber direction orthogonal to the conveying direction. At the end of the belt conveyor, a roller conveyor is provided that can protrude and immerse into the conveying surface of the belt conveyor within a plurality of row intervals forming the belt conveyor. A veneer veneer conveyed adjacently at a certain interval on the belt conveyor can be freely transferred from the belt conveyor to the roller conveyor by a roller conveyor protruding from the conveying surface at the end of the belt conveyor. Each sheet is replaced as a set (for example, a set of 4 sheets).

  Therefore, the fiber direction of the veneer single plate transferred onto the roller conveyor becomes parallel to the driving direction of the roller conveyor and is inserted as it is into each conveying stage in the veneer dryer. The veneer dryer is usually configured with a plurality of stages in the vertical direction. A plurality of veneer veneers in each conveyance stage are dried while being conveyed in each conveyance stage of the veneer dryer, and reach the terminal portion. At the terminal end of the veneer dryer, a set of veneer single plates of each conveying stage is transferred onto a belt conveyor controlled so as to be able to protrude and immerse from within each interval of the roller conveyor. For this reason, the veneer veneer is conveyed again with its fiber direction intersecting the conveyance direction.

Then, the dried veneer veneer is conveyed to the next step while being turned upside down by a reversing device. This reversing device is, for example, a pair of upper and lower belt conveyors 2 wound around a large-diameter drum pulley 1 as shown in FIG. 1 or a pair of upper and lower reversing pulleys 3 installed in the vertical distance as shown in FIG. The belt veneer 4 is sandwiched between the pair of belt conveyors 2 and conveyed.
In the next step, a processing device for cutting and rowing the veneer veneer 4 is provided. In conjunction with the insertion timing of the veneer veneer 4 into the veneer dryer, the dried veneer drier is discharged from the veneer dryer. Processing of the veneer veneer 4 is performed.

  However, the conveyance is stopped due to a shift in timing when the veneer having a fixed width and / or rectangular shape as described above is inserted into the veneer dryer, or during meandering, meandering in each conveyance stage, clogging due to drying shrinkage, etc. Sometimes. At this time, especially in the case shown in FIG. 2 described above, the veneer veneer that is in the process of being folded back may fall freely due to insufficient clamping force. Further, according to FIG. 1 described above, the occupied space of the large-diameter drum pulley 1 becomes large, and the enlargement of the apparatus becomes a problem.

  The plurality of rows of belt conveyors are controlled to synchronize the conveyance speed of each row, and the veneer single plate is conveyed while being supported by the belts of each row in a plurality of portions extending in the direction intersecting the conveyance direction. At this time, if the veneer veneer is flat, each row of belts can be conveyed evenly in contact with a plurality of parts of the veneer veneer while maintaining its posture, and is conveyed adjacent to the front and rear. The veneer veneer is held at a constant interval. However, if the veneer veneer after drying is bent, corrugated, blown, cracked, chipped, etc. due to its properties, drying stress, etc., the veneer veneer abuts on each row of belts. The part which does not generate | occur | produce occurs and the conveyance force by a belt cannot be obtained. As a result, the transport force varies between the part that contacts the belt and the part that does not contact the belt, and the transport posture is tilted due to the biased transport. Colliding with the plate causes clogging.

  Further, in the plywood factory, the veneer veneer is conveyed while being reversed, and the conveying posture may be displaced. For example, when a plywood (parallel plywood) that has been pre-pressed at room temperature by applying an adhesive to a plurality of veneer veneers is inserted into a horizontal multi-stage press or removed after hot pressing, it changes from a horizontal state to an upright state. Alternatively, the posture is displaced from the upright state to the horizontal state.

Means for Solving the Problems and Effects of the Invention

In order to solve the above-mentioned problems, the transport method of the plate body of the present invention (thin plate like a veneer single plate)
By a pair of carrier disposed opposite so as to sandwich the plate member from the front and back, the plate body forming a transport path for feeding transportable and to Oite arcuate from the starting to the conveying path termination while bending, form a guiding body as the inclination angle in the width direction of the pair of carrier in the process results in a gradual change to 3-dimensional helical locus twisted in its curvature, the transport of the pair body, by Rukoto be cyclically driven so as to run synchronously toward the end from the beginning of the conveying path along said guide member, the conveying member is a plurality of said plate member constituting the column to maintain the tension The plurality of plates supplied to the conveyance path are conveyed while being displaced from the posture at the start end position to the posture at the end position along the three-dimensionally twisted conveyance path while being in close contact with each other. It is conveyed by the conveying member The width direction of the end that intersects the transport direction of the serial plate body, wherein separately from the guide member of the conveyor path, a spiral inclination angle in the width direction of the plate body is twisted gradually changed to three-dimensionally the regulation of the order causing locus has been arranged along the conveying member, wherein the plate member is displaced successively three-dimensionally twisted helically conveyance posture by said regulating member and the conveyor member It is characterized by being conveyed.

The transport body forming the transport path is installed by rotating at an arbitrary angle with respect to the transport direction, and the transported plate body is tilted along an inclined state set by the transport body while maintaining its posture. It is displaced.
At this time, since the plate body is held and driven by the transport body, the peripheral edge of the plate body may receive a force that tends to come off the planned transport surface due to a disturbance condition such as gravity. The plate may be severely cracked or broken.
Since the regulation body for maintaining the conveyance posture of the plate body is arranged along the conveyance body at the end of the conveyance path of the present invention, for example, the movement of the plate body in the periphery is caused by the regulation body. Since the movement that suppresses cracks and breaks can be stopped by keeping them along, even if a state where the adhesion and holding power of the plate is poor due to the conveying body occurs, the plate does not have any trouble and the direction is accurate. It can now be transported while changing.

Thus, even if the transport surface of the transport path changes between the start end position of the transport body and the end position of the transport body, the plate body can be transported reliably by the function of the restricting body. The installation form at the start end position can be any of an inclined state, a vertical state, and a horizontal state, and the installation form at the end position can be any of a horizontal state, an upright state, and an inclined state.
That is, the conveyance surface at the start end position of the conveyance body and the regulation body can be set to any arbitrary inclined surface, and the conveyance surface at the end position can be set to any different inclined surface. Moreover, the conveyance surface in the starting end position of a conveyance body and a control body can be made into a vertical surface, and the conveyance surface in the terminal position can be set to a horizontal surface. It is also possible to set the transport surface at the start end position of the transport body and the restricting body to a horizontal plane and set the transport surface at the end position to a vertical plane. The installation form of the transport surfaces of the transport body and the regulation body can be arbitrarily set based on the displacement posture of the transported plate body.

  Furthermore, as these installation forms, the conveyance body and the regulation body are generated so that the conveyance surface is inclined while being inclined from the horizontal plane and again reaches the horizontal plane, and the conveyance posture of the plate body is sequentially displaced toward the conveyance direction while It is also possible to reverse the front and back surfaces. And the said conveyance body and a regulation body arrange | position the height of the conveyance surface differently in the start end position and the termination | terminus position, and when the plate body conveyed is conveyed from the beginning end of the conveyance path to the termination | terminus, It is also possible to install with the posture being displaced and the conveying height being different.

  The transport body can be set by reducing the contact area in the direction intersecting the transport direction of the plate body. That is, the conveyance body is not in contact with the entire width of the plate body, and is in close contact with the contact area with the plate body, and the contact area is preferably the conveyance center of the plate body. It is made into the site | part of the center vicinity over the direction which cross | intersects the conveyance direction applicable to a line. In this case, in order to ensure the clamping state of the plate body, it is desirable to configure the pair of opposed conveying bodies with members having a tensioned state and / or a high friction coefficient. Therefore, the bias conveyance as described above is prevented, and the plate body is conveyed in a state in which the posture is maintained, and inconveniences such as collision with the next plate body adjacent to the front and rear are avoided.

  In particular, if there is a difference in height between the transport start end position and the transport end position of the plate body, and the transport body is in contact over almost the entire width of the plate body, the plate body is moved inside and outside during the process of descending while being twisted. A circumferential speed difference occurs. For this reason, for example, when the plate body is a fragile material such as a veneer veneer, a tensile force is generated at a portion located on the outer side in the transport direction, and cracks, breaks, tears, etc. in the fiber direction occur. Cause. However, as described above, if the transport body is arranged in a portion around the center of the plate body and the contact area with the plate body is generated so as to be extremely small and in close contact with the plate body, the plate body has an adverse effect due to a difference in peripheral speed. Is eliminated.

  Further, in an arbitrary transfer region extending from the start end to the end of the transfer path, the pair of the transfer body and the regulating body are rotated by an arbitrary angle with respect to the transfer direction while being rotated approximately 180 degrees at the end portion. It is also possible to reverse the front and back surfaces of the plate at the end position of the plate supplied to the transport path.

In addition, the regulation body constituting a part of the transport path is a position where the transport body is displaced toward the transport direction at a position supporting lower portions near both ends in the transport direction of the plate body sandwiched and transported by the transport body. It is attached in an arbitrary transfer area from the start end to the end in accordance with the transfer state.
As a preferred embodiment, the restricting body is preferably composed of a member having a low friction coefficient, and the restricting body is composed of a tubular or polygonal member and extends in the conveying direction. It is attached.

  Therefore, the plate body is sandwiched by the conveyance body at a portion around the center in the direction intersecting the conveyance direction, and both ends thereof are supported and conveyed by the regulation body. For this reason, the plate body is formed only by the conveyance body. When the plate body is a fragile material such as a veneer veneer, a tensile force is generated in the part located on the outer side in the conveyance direction, and cracks, breaks, tears, etc. in the fiber direction However, when the regulator supports the lower surface of the end of the plate in the direction crossing the conveying direction where the tensile force is applied, cracks, breaks, tears, etc. may occur at the end of the plate. It can be prevented beforehand.

  In particular, if there is a difference in height between the transport start end position and the transport end position of the plate body, and the transport body is in contact over almost the entire width of the plate body, the plate body is moved inside and outside during the process of descending while being twisted. A circumferential speed difference occurs. For this reason, for example, when the plate body is a fragile material such as a veneer veneer, a tensile force is generated at a portion located on the outer side in the transport direction, and cracks, breaks, tears, etc. in the fiber direction occur. Cause. However, the tensile force is generated at the part located outside the transport direction, and cracks, breaks, tears, etc. in the fiber direction are likely to occur at the end of the plate, but cross the transport direction where the tensile force is applied. Since the regulating body supports the lower surface of the end portion of the plate body in the direction to be cut, it is possible to prevent the occurrence of cracks, breaks, tears and the like at the end portion of the plate body.

  The regulating body is constituted by a regulating belt conveyor arranged by a belt wound between pulleys over the conveying direction, and supports the vicinity of the end in the direction intersecting the conveying direction of the plate body by the regulating belt conveyor. is doing. In other words, the regulation belt conveyor is maintained in a tension state, and for example, the regulation belt conveyor wound around the intermediate pulley between the front and rear pulleys is pressed by placing a tie pulley on the way, and always I am nervous. For this reason, the belt of the regulation belt conveyor always supports the vicinity of the end portion of the transported plate body, and the vicinity of the end portion of the plate body is reliably supported.

  The regulation body is constituted by a regulation chain conveyor arranged by chains wound between chain wheels across the conveyance direction, and supports the vicinity of the end in the direction intersecting the conveyance direction of the plate body by the regulation chain conveyor. is doing. That is, the restriction chain conveyors are maintained in tension with each other. For example, the restriction chain conveyor wound around the intermediate chain wheel between the front and rear pulleys is arranged with a tyner pulley in the middle and pressed. Has always been in tension. For this reason, the chain of the restriction chain conveyor always supports the vicinity of the end portion of the transported plate body, and the vicinity of the end portion of the plate body is reliably supported.

  The regulation body is constituted by a conveyor with a regulation roller arranged by a chain with regulation rollers wound between pulleys in the conveyance direction, and the conveyor in the direction intersecting the conveyance direction of the plate body by the conveyor with the regulation rollers. Supports the vicinity of the end. In other words, the conveyor with restriction rollers is maintained in a tensioned state. For example, the conveyor with restriction rollers wound around the intermediate pulley between the front and rear pulleys is pressed by placing a tie pulley on the way. , Always in tension. For this reason, the roller-attached chain of the conveyor with the regulation roller is always supported in the vicinity of the end portion of the conveyed plate body, and the vicinity of the end portion of the plate body is reliably supported.

  The regulating body is constituted by a regulating roller conveyor composed of a plurality of rolls arranged adjacent to each other with the direction intersecting the conveying direction as the rotation axis direction, and intersects the conveying direction of the plate body by the regulating roller conveyor. Supports the vicinity of the end of the direction. That is, since the rotating shaft of the rolls constituting the regulating roller conveyor is in a direction intersecting the transport direction, the transported plate body can be moved by the rotating roll. For this reason, the vicinity of the end portion of the plate body to be conveyed is surely supported by the roll of the regulating roller conveyor.

In addition, in order to solve the above problem, the plate conveying apparatus of the present invention is
A pair of conveying bodies arranged to face each other so as to sandwich the plate body from the front side and the back side ;
Formed by the pair of carrier, a transport path for feeding transportable pre Symbol plate body,

At the end in the width direction of the plate body transported by the transport body, apart from the guide body of the transport path , located at the end portion in the width direction of the plate body, the inclination angle in the width direction is the regulation of the order cause gradual changes to three-dimensionally spiral locus twisted arranged along the conveying member,
The plate body is transported while the transport posture is sequentially twisted in a three-dimensional manner by the transport body and the regulating body.

When the transported plate body is transported while changing its posture from the start end to the end of the transport path, the transport path of the plate body formed by the transport body and the regulating body has its start end position and end position. It is also possible to arrange the transport height differently, and when there is a difference between the height position of the start end of the transport path and the height position to which the transported plate body is delivered, this transport path is It is possible to handle height differences while displacing the posture.
The transport body can be set by reducing the contact area in the direction intersecting the transport direction of the plate body. That is, the conveyance body is not evenly in contact with the entire width of the plate body, and the contact area with the plate body is set to be extremely small, and the contact area is preferably a conveyance direction corresponding to the conveyance center line of the plate body. It is made into the site | part around the center of a board body covering the direction which cross | intersects. For this reason, each conveyor will be arrange | positioned in the state of contact | adherence limitedly in the site | part of the center vicinity over the direction which cross | intersects the conveyance direction of a board | plate body.

Also preferably, the plate conveying apparatus of the present invention comprises:
The conveyance path of the plate body is formed by a pair of conveyance bodies arranged opposite to each other and a regulation body positioned at an end portion in a direction intersecting the conveyance direction of the plate body, and the conveyance body extends over the conveyance direction. A pair of belts wound between pulleys are opposed to each other, and the pair of belt conveyors is disposed at a portion around the center of the plate body so that a small contact area with the plate body The plate is sandwiched and conveyed between the pair of belt conveyors in close contact with each other, and the regulation body is formed of a tubular or polygonal member and is substantially the same as the pair of belt conveyors. The lower surface of the end portion that is arranged on the same conveyance surface and intersects the conveyance direction of the plate body is supported by this regulating body, and one of the belt conveyors is twisted over the conveyance direction from the start end to the end. And a guide pulley is rotatably mounted at an arbitrary interval in the longitudinal direction of the guide body, and the guide pulley supports the back surface of the belt conveyor. While rotating the sheet at an arbitrary angle with respect to the transport direction, the front and back surfaces of the plate body are reversed by rotating approximately 180 degrees at the end portion.

  In addition, in the transport region from the start end to the end of the transport path formed by the transport body, the transport surface for transporting the plate bodies of the pair of transport bodies facing each other in order to ensure the clamping state of the plate body has a high friction coefficient. It is a desirable means to constitute the member. Further, in the transport region from the start end to the end of the transport path, at least one of the transport bodies is provided with a guide body that generates a twisted transport path in the transport direction, and the guide body extends along the longitudinal direction. It is also possible to support the back surface of the transport body, and an accurate transport path can be configured by this guide body, so that the plate body can be transported reliably.

  Further, the transport body is constituted by a belt conveyor in which a pair of belts wound between pulleys are opposed to each other in the transport direction, and the belt conveyor disposed so as to face each other has a certain constant with respect to the transport surface. A conveyance path for pressing the plate with the pressure of is formed. That is, the pair of belt conveyors are maintained in tension with each other. For example, a belt of a belt conveyor wound around an intermediate pulley between the front and rear pulleys is pressed by placing a tie pulley on the way. Has always been in tension. For this reason, the belt of the belt conveyor is always in close contact with the transported plate body, and the plate body is reliably transported without slipping.

Are pressed against each other.

In general, a veneer dryer (not shown) for drying the veneer veneer 10 is usually configured to have a plurality of stages in the vertical direction. And any veneer veneer 10 of any dimension width (2 scale width, 3 scale width, 4 scale width...) Has a direction in which the fiber direction is parallel to the conveying direction, and one set for each arbitrary number of sheets. (For example, a set of four sheets) is inserted into each conveying stage of the veneer dryer. The veneer veneer 10 of a set of a plurality of sheets at each conveyance stage of the veneer dryer is dried while being conveyed at each conveyance stage of the veneer dryer, and is transferred onto the conveyance conveyor 11 connected at the terminal portion.
The conveyor 11 connected at the terminal end side of the veneer dryer is constituted by a roller conveyor, and within the roll interval of the roller conveyor, a belt conveyor that is controlled to be able to protrude and immerse is disposed. It is transferred to a belt conveyor protruding upward from within each interval of the conveyor. For this reason, the veneer veneer 10 is conveyed in series on the conveyor 11 constituted by a belt conveyor in a state where the veneer veneer 10 intersects the conveying direction again in series. become.
Then, at the end of the conveyor 11, a transport path 13 is transported to the next processing step by the second conveyor 12 while displacing the dried veneer veneer 10 one by one, such as turning over one by one. It is connected.

The conventional example of the transport path 13 is shown in FIG. 1 and FIG. 2, but as will be described with reference to FIGS. 3 to 20 according to each embodiment of the present invention, the present invention provides the transport path 13. It is an improvement. The transport path 13 is composed of a pair of transport bodies 14 arranged opposite to each other and a regulating body 60 positioned at an end portion in a direction intersecting the transport direction of the veneer single plate 10. The transport body 14 sandwiches the central portion in the direction intersecting the transport direction of the veneer veneer 10, while the regulating body 60 supports the lower surface of the end of the veneer veneer 10 and transports it to the next processing step. One sheet is sent out toward the second conveyor 12 for carrying out.
FIG. 3 shows an embodiment of the transport body 14 according to one embodiment of the present invention. The pair of transport bodies 14 in this embodiment includes an inner belt 16 and an outer belt which are driven in conjunction by a driving device (not shown). The belt conveyor 15 which consists of 17 is comprised. A pair of front pulleys 18 are disposed on the conveyor 11 side, and a pair of rear pulleys 19 are disposed on the processing step side. Intermediate pulleys 20 are interposed between the front and rear pulleys 18 and 19, respectively. A pair of belt conveyors 15 is driven by rotating any one of 18 and 19 or the intermediate pulley 20 by a driving device (not shown).
The pair of belt conveyors 15 oppose the front and rear pulleys 18 and 19 and the inner belt 16 and the outer belt 17 wound around the intermediate pulley 20 on the conveying surface of the veneer single plate 10.
Further, the inner and outer belts 16 and 17 between fixed pulleys such as the intermediate pulley 20 of the belt conveyor 15 are pressed by an internal spring device, and the inner and outer belts 16 wound around the belt conveyor 15 are pressed. A tie pulley 21 is disposed as appropriate to maintain the 17 tension state.

The pair of belt conveyors 15 constituting the transport body 14 receives the veneer veneer 10 from the transport conveyor 11 side at the start position, and delivers the veneer veneer 10 to the second transport conveyor 12 at the end. Become. The conveyance path 13 of the veneer veneer 10 during this time is provided with a difference in height between the start position and the end position, the conveyance direction is bent and converted into an L shape, or the conveyance direction is converted to an orthogonal state, or the conveyance direction It is provided with a form in which the front and back surfaces are reversed by twisting the surface.
As shown in the embodiment of FIGS. 6 and 7, the second transport conveyor 12 disposed below the transport conveyor 11 transports the veneer veneer 10 in the direction opposite to the transport conveyor 11. This forms one form of the transport path 13 that has a height difference between the position and the end position and is generated by reversing the transport direction. The transport body 14 constituting the transport path 13 is formed with a semicircular curvature in an arbitrary transport region from the start end to the lower end disposed with a height difference, From the start end to the end, the position of the transfer surface of the transfer body 14 is displaced by approximately 180 degrees. For this reason, the upper surface of the veneer single plate 10 which is conveyed by the conveyance conveyor 11 becomes the lower surface of the second conveyance conveyor 12, and the veneer single plate 10 can be conveyed by being reversed by the conveyance body 14. Is reliably held between the pair of belt conveyors 15 and can be transported toward the second transport conveyor 12 without disturbing the transport mode.

In addition, when the transport path 13 is reversed to a U-shape as described above, or is constituted by a pair of transport bodies 14 along a semicircular curvature bent into an L-shape as another form, the embodiment of FIG. In addition to the inversion as described above, the conveyance path 13 can be configured with further twists as in the embodiment of FIG.
That is, the transport body 14 configured by a belt conveyor 15 having a pair of curved transport surfaces is configured by reducing the contact area in the direction intersecting the transport direction of the veneer veneer 10 and twisting the transport surface. The pair of belt conveyors 15 can be operated even in a state in which is added.
If it is this conveyance form, the belt conveyor 15 can set the contact area with the veneer veneer 10 very few, without contacting uniformly with respect to the full width of the veneer veneer 10, and the contact area is suitably Even if the portion around the center in the direction intersecting the conveyance direction corresponding to the conveyance center line of the veneer veneer is in close contact with the belt of the belt conveyor 15, the conveyance surface has a twist. The veneer veneer 10 can be reliably conveyed.
In this way, when the belt conveyor 15 is limitedly disposed in a region around the center in the direction intersecting the conveying direction of the veneer veneer 10, it is surely conveyed even on a conveying surface having a twist. In order to secure the sandwiched state of the veneer veneer 10, a pair of opposed belt conveyors 15 are formed with rubber on the conveying surface that the veneer veneer 10 conveys, and the surface is formed with irregularities, etc. It is desirable that the veneer veneer 10 is made of a material having a high coefficient of friction that increases the conveyance holding force.

In the embodiment shown in FIG. 3, the veneer veneer 10 inserted horizontally from the transport conveyor 11 into the pair of transport bodies 14 is guided by the transport body 14 along a semicircular curvature and twisted 180 degrees. The veneer veneer 10 is turned upside down when it is conveyed and reaches the end. In other words, the veneer veneer 10 is inevitably reversed by being conveyed along a semicircular curvature, and substantially when the veneer veneer 10 is transferred to the second transfer conveyor 12, the transfer path. Similarly to the start position of 13, the inserted horizontal state is restored.
Further, in the embodiment of FIG. 3, the transport direction of the second transport conveyor 12 is twisted so as to be different from the transport conveyor 11 by 90 degrees. In the embodiment of FIG. The conveyance direction of the veneer veneer 10 can be conveyed in an arbitrary direction while keeping the posture of the plate 10 in the original horizontal state, and a very versatile conveyance path 13 is disclosed.

In addition to the horizontal state of the illustrated veneer veneer 10 depending on the form of the conveyor 11, the veneer veneer 10 is held in an inclined state or a horizontal state. A conveying conveyor 10 for conveying is well known, and the conveying apparatus of the present invention can make the veneer veneer 10 in any of an inclined state, a vertical state, and a horizontal state.
That is, since the transport body 14 is configured by reducing the contact area in the direction intersecting the transport direction of the veneer veneer 10, the transport surface at the starting end position of the transport body 14 is adjusted to an arbitrary transport conveyor 11. The veneer veneer 10 can be conveyed as an inclined surface. Moreover, the conveyance surface in the terminal position can be set to the other inclined surface matched with arbitrary 2nd conveyance conveyors 12.
At this time, the conveyance surface at the start end position of the conveyance body 14 can be set as a vertical surface, and the conveyance surface at the end position can be set as a horizontal plane. It is also possible to set the conveyance surface at the start end position of the belt conveyor 15 as a horizontal plane and the conveyance surface at the end position as a vertical plane. Such displacement of the position of the veneer veneer 10 from the vertical state to the vertical state is particularly effective for insertion into and removal from a horizontal multi-stage press. The installation form of the conveyance surface of these conveyance bodies 14 can be arbitrarily set based on the displacement attitude | position of the veneer single board 10 conveyed.

In this way, an embodiment using a pair of belt conveyors 15 is disclosed with reference to FIGS. 3 to 5 in order to construct a conveying surface having a difference in height from the starting end position to the ending position of the conveying member 14 and torsion. is doing.
That is, since the conveyor 14 has a height difference and forms a conveyor surface to which twist is applied, at least the back side of the curved belt conveyor 15 matches the shape of the conveyor surface of the conveyor 14. A guide body 22 is installed. The guide body 22 is formed on the basis of the conveying displacement position of the veneer veneer 10 and is formed by deforming the long rod-shaped body under a certain curvature matching the shape of the conveying surface of the conveying body 14. ing. The starting end faces the terminal end of the conveyor 11 and the other end faces the front end of the second conveyor, and is directed to the processing step of the next veneer veneer 10.

The guide body 22 composed of this long rod-shaped body is in an arbitrary transport area from the start end of the transport path 13 of the veneer single plate 10 to the lower end disposed with a difference in height. The veneer veneer 10 is transported from the transport conveyor 11 toward the second transport conveyor 12 whose transport direction has been changed.
The curved guide body 22 is arranged on the back side of the inner belt 16 of the belt conveyor 15 in FIG. As shown in detail in FIGS. 4 and 5, a plurality of guide pulleys 23 are provided between the inner belt 16 and the guide body 22 at arbitrary intervals in the longitudinal direction of the guide body 22. 24 is rotatably mounted. As shown in FIG. 3, the guide pulley 23 is positioned outside the curved guide body 22 and supports the back surface of the inner belt 16.
Each guide pulley 23 that supports the back surface of the inner belt 16 is attached by being rotated by an arbitrary angle along the longitudinal direction of the guide body 22 so that the transport surface of the transport body 14 is twisted in the transport direction. It is possible to generate so as to be generated.
That is, in the form of the embodiment shown in FIG. 3, the guide pulley 23 is located below the veneer veneer 10 that is transported by being positioned above the guide body 22 at the start end position of the transport path 13 on the transport conveyor 11 side. Located on the side. However, the terminal pulley is located below the veneer veneer 10 that is transported in a position below the guide body 22, and the guide pulley 23 extends from the start end position of the transport path 13 to the end position. It will be attached in a state of being rotated approximately 180 degrees.

Further, the guide body 22 is generated along a semicircular curvature, and a plurality of guide pulleys 23 are rotatably attached via brackets 24 at arbitrary intervals along the longitudinal direction thereof. For this reason, the guide pulley 23 supports the back surface of the inner belt 16 of the belt conveyor 15, and the outer belt 17 also follows the semicircular curvature from the outside and is in close contact with the inner belt 16. 23.
At this time, each guide pulley 23 is rotated and attached at an arbitrary angle with respect to the longitudinal direction of the guide body 22, so that the conveying surface of the belt conveyor 15 is twisted in the conveying direction, and its upward starting end. As a result, the position of the guide pulley 23 was displaced by approximately 180 degrees from the end to the downward end, and the transport surface of the veneer veneer 10 could be twisted in the transport direction of the second transport conveyor 12.

The transport surface of the transport body 14 is inverted by displacing the transport surface by the guide body 22 and a guide pulley 23 attached to the guide body 22. Therefore, the veneer veneer 10 inserted into the pair of belt conveyors 15 from the transport conveyor 11 rotates in a twisted manner along the transport path 13 formed in a twisted state by the pressing state from each guide pulley 23. Then, it descends, and at its terminal position, it is rotated approximately 180 degrees with the displacement in the transport direction, and the front and back surfaces are reversed.
Thus, when there is a difference in height between the conveyance start end position and the conveyance end position of the veneer veneer 10 and an arc-shaped curvature is formed in the conveyance path, the inside of the veneer veneer 10 is lowered while being twisted. A circumferential speed difference occurs on the outside.
However, as described above, if the belt conveyor 15 is disposed in a region around the center of the veneer veneer 10 and has a very small contact area with the veneer veneer 10 and is in close contact with the veneer veneer 10, The adverse effects caused by the inner peripheral speed difference are eliminated.
