JP 63-60701 A

According to such a single plate edge alignment method, alignment work can be performed more efficiently than alignment work that depends on the visual and manual work of the worker.
However, the preceding plate-like body such as a single plate is moved in a direction perpendicular to the conveying direction of the plate-like body to the line where the subsequent plate-like body waits, and the peaks and valleys formed at the edge of the plate-like body are In the conventional method in which a portion is photoelectrically detected and measured by a detector or the like, and the positional deviation is corrected by a movement correction mechanism, the entire conveying device is necessarily increased in size and complexity. In addition, when a plate-like body whose lower end in the transport direction is cut into a zigzag shape is positioned and stopped at a predetermined position, the top of the portion that becomes the crest of the plate-like body is a stopper constituted by a flat plate or the like. Since it will contact | abut to a surface part, there exists a possibility that the front-end | tip of the part used as a peak may deform | transform. This may lead to a deterioration in quality, such as failure of good bonding and loss of product.

  In order to solve the above-mentioned problems, the present invention transports a plate-like body that can be accurately positioned while preventing deformation of the lower end of the plate-like body in the transport direction by a simpler method. It is an object to provide an apparatus and a conveying method thereof.

  In order to solve the above problems, the inventor of the present application proposes the following plate-like body conveyance device and its conveyance method.

The plate-shaped material conveyance device of the present invention includes a conveyance mechanism for conveying a plate-shaped material having at least one end processed into a zigzag shape, and a positioning stopper for stopping the plate-shaped material at a predetermined position. It is a conveyance apparatus of the plate-shaped object provided. This positioning stopper includes two or more protrusions protruding in the direction opposite to the conveying direction of the plate-like body. The convex portion of the positioning stopper is in contact with a portion that becomes a valley of the plate-like body.
According to such a plate-shaped conveyance device, the convex portion formed on the positioning stopper is formed into a zigzag-shaped valley formed at the lower end in the conveyance direction of the plate-shaped material that has been conveyed. Since the plate-like body can be stopped at a predetermined position by abutting it in, it is possible to stop while aligning the transport angle by simply setting a positioning stopper in advance at the position where the plate-like body is to be stopped. It is possible to easily and accurately transport the plate-like body to the desired position.

The same object as described above can also be achieved by the following method.
That is, in the plate-shaped material transporting process in which the plate-shaped body having at least one end processed into a zigzag shape is transported by a transport mechanism, and the plate-shaped body is stopped at a predetermined position by the positioning stopper, as the positioning stopper, By using a positioning stopper having two or more convex portions protruding in the direction opposite to the conveying direction of the plate-like body, the convex portion of the positioning stopper is formed in a portion that becomes a valley of the plate-like body that has been conveyed. In this method, the plate-like body is stopped at a predetermined position by bringing a portion into contact therewith.

Further, when the convex portion of the positioning stopper of such a plate-shaped conveyance device is in contact with a portion that becomes a valley of the plate-shaped material, it is poor in the conveyance direction processed into a zigzag shape of the plate-shaped material. The distal end portion of the side end portion may be configured so as not to contact the positioning stopper.
Since the lower end portion in the conveyance direction of the plate-like body is cut into a zigzag shape, the vicinity of the tip of the portion that becomes the peak of the end portion of the plate-like body is very thin and brittle. When a plate-like body whose end has been cut into a zigzag shape is positioned and stopped by the conventional positioning method described above, the apex of the portion that becomes the peak of the plate-like body is constituted by a flat plate or the like. Since it will contact | abut to the surface part of a stopper, there exists a possibility that the front-end | tip of a plate-shaped body may deform | transform. This may lead to a deterioration in quality, such as failure of good bonding and loss of product.
The present invention has been made paying attention to such a point, and according to the plate-shaped body conveyance device having the positioning stopper having such a configuration, the crest at the lower end portion in the conveyance direction of the plate-shaped body Can prevent the tip of the portion from coming into contact with the positioning stopper, so that the tip can be prevented from being damaged or deformed by contact with the positioning stopper. When bonding to other plate-like bodies, a good adhesion surface can be obtained. Thereby, the quality improvement of a product can be aimed at.

When the convex portion comes into contact with a portion that becomes a valley of the plate-like body, the tip of the lower end portion in the transport direction processed into the zigzag shape of the plate-like body may not be in contact with the positioning stopper. Any shape may be used, and for example, the height may be higher than the height of the portion that becomes the peak of the plate-like body.
According to the plate-shaped conveyance device having the positioning stopper having such a configuration, the apex of the convex portion formed on the positioning stopper is a zigzag-shaped valley formed at the lower end in the conveyance direction of the plate-shaped material. When the conveyance of the plate-like body is stopped by coming into contact with the bottom of the portion, the tip of the crest at the end of the plate-like body does not contact the positioning stopper.

The positioning stopper may include one or more continuous convex portions, and a hole may be formed in a portion serving as a bottom of the concave portion that is formed between the continuous convex portions in the positioning stopper. Good.
According to such a plate-shaped body conveyance device having a positioning stopper, the processing accuracy of the portion that becomes the crest of the plate-shaped body is poor, and a burr is formed near the apex, or a continuous protrusion in the positioning stopper. Even if processing waste etc. are sandwiched between the concave portion that will be formed between the parts and the portion that becomes the crest of the plate-like body, this burr and processing waste etc. can escape to the hole, It is possible to prevent the accurate positioning from being hindered.

The convex portion of the positioning stopper has a chamfered tip, and when the convex portion and the portion that becomes the valley of the plate-like body are brought into contact with each other, the convex portion and the portion that becomes the valley It may be configured in such a shape that a space is formed between them.
If the processing accuracy of the part that becomes the valley of the plate-like body is poor, or if processing scraps are sandwiched between the convex part of the positioning stopper and the part that becomes the valley of the plate-like body, the plate-like body is accurately positioned. It may not be possible. The present invention has been made paying attention to this point, and if a positioning stopper having a convex portion having such a shape is used, the convex portion of the positioning stopper and the portion that becomes the valley of the plate-like body are provided. When contacted, it is possible to release the processing waste or the like into the gap (interval) between the convex portion and the portion that becomes the valley of the plate-like body, so that it is possible to prevent accurate positioning from being hindered. .

The positioning stopper in the other plate-shaped material conveying apparatus of the present invention comprises two or more arc portions whose cross-sectional shape in a plane parallel to the surface of the plate-shaped material protrudes in the direction opposite to the conveying direction, A portion that becomes a valley of the plate-like body is in contact with an outer peripheral portion of the arc portion.
According to such a plate-shaped conveyance device having a positioning stopper, the outer peripheral portion of the arc portion in which the cross-sectional shape in a plane parallel to the plate-shaped surface of the positioning stopper protrudes in the direction opposite to the conveyance direction. In addition, the zigzag valley that has been machined into contact with the lower end of the transported plate-shaped body comes into contact and stops, so that the plate-shaped body is positioned in advance at the position where it is desired to stop. By setting the stopper for the plate, the plate-like body can be easily and accurately conveyed to the position where it is desired to stop while aligning the conveyance angle. In addition, when the positioning stopper and the part that becomes the valley of the plate-like body abut, the tip of the lower end in the transport direction processed into a zigzag shape of the plate-like body does not contact the positioning stopper. Good joining can be performed without deforming the tip of the peak of the ridge. Thereby, the quality improvement of a product can be aimed at.

  According to the present invention, positioning can be performed accurately by a simpler method.

  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of a plate-like material conveying device and a conveying method thereof according to the present invention will be described in detail with reference to the drawings.

The plate-shaped conveyance apparatus in the present embodiment is schematically configured as shown in FIGS. 1 and 5.
As shown in these drawings, the plate-shaped conveyance device 1 according to the present embodiment includes a guide 10 for determining an approximate placement position of the plate-shaped body, a conveyor 20 for placing and moving the plate-shaped body, and a conveyor. 20, a motor 21 for operating the plate 20, a feed detection roll 30 for measuring the movement distance of the plate-like body and detecting the stop of the plate-like body, a positioning stopper 40 for stopping the plate-like body at a predetermined position, positioning A first air cylinder 45 for raising and lowering the stopper and a control device 50 for controlling the running and stopping of the conveyor.

In the present embodiment, the plate-like body to be transported is described as using plywood. However, the present invention is not limited to this, and the plate-like body is a wood board such as a single board, MDF, particle board, or heat insulation. It may be of a material such as wood, gypsum, asbestos board.
In addition, as shown in FIG. 2, the plywood 100 in this embodiment has a direction in which the lower end of the conveyance direction is orthogonal to the conveyance direction so that the bonding area can be as large as possible when bonded to another plywood. In addition, it is cut into a scarf shape in advance, and further, the portion is cut into a zigzag shape. Therefore, as shown in FIG. 3, the end portion of the plywood 100 cut into a zigzag shape includes a portion 100 a that becomes a peak protruding in the conveyance direction of the plywood, and a portion that becomes a valley that retreats in the direction opposite to the conveyance direction. 100b is formed. In addition, although the both ends of the plywood 100 of FIG. 2 are processed into the zigzag shape, you may use the plywood by which only the one end was cut into the zigzag shape, and as shown in FIG. A plywood 101 that is not cut into a scarf shape may be used at the end.

The guide 10 is installed horizontally with the conveying direction of the plywood 100. By placing the plywood 100 on the conveyor 20 along the guide 10, the approximate placement position of the plywood 100 is determined. The feed detection roll 30 is installed and used on the plywood 100 placed on the conveyor 20 such that the roll portion abuts against the surface of the plywood 100. The feed detection roll 30 is configured such that when the plywood 100 is conveyed by the conveyor 20, the roll rotates accordingly, and when the movement of the plywood stops, the rotation of the roll also stops.
The positioning stopper 40 is installed on the lower side in the K direction, which is the conveying direction of the plywood placed on the conveyor 20. As shown in FIG. 5, the positioning stopper 40 includes convex portions protruding in the direction opposite to the K direction, which is the conveyance direction of the plywood 100, with an interval in the direction orthogonal to the conveyance direction. Moreover, as shown in FIG. 7, the height h1 of the convex part of the positioning stopper 40 is formed higher than the height h2 of the part 100a which becomes the peak of the plywood end part.

Next, as a first embodiment, a flow until a single plywood is positioned by the plate-like body conveyance device of the present embodiment will be described.
First, as shown in FIG. 5, the plywood 100 to be conveyed is placed on the conveyor 20 along the guide 10, and the approximate placement position of the plywood 100 is determined. On the plywood 100A and the plywood 100B placed on the conveyor, feed detection rolls 30A and 30B are installed in such a manner that their roll portions abut against the surfaces of the plywood 100A and the plywood 100B, respectively. Further, a positioning stopper 40 is set in advance at a position where the plywood 100 is to be stopped.
After that, when the plywood conveying device 1 is operated, the motor 21 is driven under the control of the control device 50 and the conveying of the plywood 100 by the conveyor 20 in the K direction is started. If conveyance of the plywood 100 by the conveyor 20 is started, the feed detection roll 30 will rotate in connection with it.

  As described above, the positioning stopper 40 is installed on the lower side in the K direction, which is the conveying direction of the mounted plywood 100, and when the plywood 100 is conveyed in the K direction by the conveyor 20, the plywood is eventually used. The lower end of the transport direction 100 abuts against the positioning stopper 40.

Here, since the plywood 100 is cut into a zigzag shape in the direction perpendicular to the conveyance direction at the lower end in the conveyance direction, the end portion of the plywood 100 is a portion 100a that becomes a peak protruding in the conveyance direction, A trough portion 100b that is recessed in the direction opposite to the transport direction is formed (FIG. 3). On the other hand, convex portions protruding in the direction opposite to the conveying direction of the plywood 100 are formed on the positioning stopper 40 with an interval in a direction orthogonal to the conveying direction (FIG. 5).
Therefore, when the plywood 100 abuts against the positioning stopper 40, the convex portions formed on the positioning stopper 40 abut on the plywood 100 so as to enter the zigzag valley 100b.
Therefore, when the plywood 100 is placed on the conveyor 20, because the plywood 100 is placed slightly apart from the guide 10, the plywood 100 has been transported in a state slightly deviated in the direction orthogonal to the transport direction, Even if the plywood 100 is transported in a state of being shifted in an oblique direction by placing the plywood 100 obliquely, as shown in FIG. 6, peaks and valleys formed at the end of the plywood 100 7 is brought into contact with the convex portion of the positioning stopper 40 and comes into contact with the convex portion of the positioning stopper 40, and when the abutment with the convex portion of the positioning stopper 40 is completed, as shown in FIG. The shift in time is completely corrected, and the position of the plywood 100 in the transport direction and the position in the direction orthogonal to the transport direction are simultaneously positioned.

Further, as shown in FIG. 7, the height h1 of the convex portion of the positioning stopper 40 is higher than the height h2 of the portion 100a which becomes the peak of the plywood 100 cut into a zigzag shape. When the convex portion of the positioning stopper 40 contacts the portion 100b that becomes the valley of the end of the plywood 100, the tip of the portion 100a that becomes the peak of the end of the plywood 100 comes into contact with the positioning stopper 40. It can be avoided.
Since the end portion of the plywood 100 is cut into a scarf shape as described above and further cut into a zigzag shape, the vicinity of the apex of the portion that becomes the peak of the end portion of the plywood 100 is very thin and brittle. However, according to the plywood transport device of the present embodiment, it is possible to avoid the tip part of the part that becomes the crest of the end part of the plywood 100 from coming into contact with the positioning stopper 40. Can be prevented from being damaged or deformed by contact with the positioning stopper 40, and a good adhesion surface can be obtained when the plywood 100 is joined to another plywood.

  As described above, when the plywood 100 conveyed by the conveyor 20 contacts the positioning stopper 40, the positional deviation of the plywood 100 is completely corrected and positioning is performed, and at the same time, the movement of the plywood 100 in the K direction is determined by positioning. Stopped by the stopper 40 for use. When the movement of the plywood 100 is stopped, the rotation of the roll portion of the feed detection roll 30 is stopped, and the rotation stop signal is immediately sent to the control device 50, and the control device 50 controls to stop the motor 21 of the conveyor 20. .

  When the motor 21 of the conveyor 20 is stopped, the control device 50 controls the first air cylinder 45 to lower the positioning stopper 40, and when the positioning stopper 40 is lowered, drives the motor 21 again. Then, the plywood 100 positioned by the conveyance by the conveyor 20 passes over the lowered positioning stopper 40.

  As described above, according to the plywood conveyance device of the present embodiment, positioning can be accurately performed while preventing deformation of the lower end portion in the conveyance direction of the plywood by a simpler method.

In the present embodiment, the positioning stopper 40 has been described as having a configuration in which the height of the convex portion is higher than the height of the portion 100a that becomes the crest of the plywood 100 cut into a zigzag shape. However, the positioning stopper is not limited to this, and the positioning stopper includes two or more protrusions protruding in the direction opposite to the plywood conveyance direction, and the protrusion of the positioning stopper hits the portion of the plate-like body. What is necessary is just to become the structure which touches. The convex portion is not limited to a triangular shape, and may be an elliptical shape or the like. With the positioning stopper having such a configuration, as described above, the displacement during the conveyance of the plywood is completely corrected, and the position in the conveyance direction of the plywood 100 and the position in the direction perpendicular to the conveyance direction can be positioned simultaneously. can do.
Furthermore, when a plywood is bonded to another plywood, in order to obtain a good adhesion surface, when the convex portion of the positioning stopper is in contact with the portion that becomes the valley of the plywood, What is necessary is just to comprise in the shape where the front-end | tip part of the conveyance direction lower end part processed into the zigzag shape does not contact the stopper for positioning. In this case, for example, a positioning stopper having a configuration as shown in FIGS. 8 to 11 can be used.

The positioning stopper 41 shown in FIG. 8 includes continuous protrusions 41a and 41b that protrude in the direction opposite to the plywood conveyance direction, with a gap in the direction orthogonal to the conveyance direction. A hole 41c is formed in a portion serving as the bottom of the concave portion which is formed between the continuous convex portions 41a and 41b.
According to the plywood conveyance device having the positioning stopper 41 having such a configuration, as shown in FIG. 9, when the processing accuracy of the portion 100a which becomes the plywood crest is poor and a burr is formed near the apex, When processing waste or the like is sandwiched between the concave portion to be formed between the continuous convex portions in the positioning stopper 41 and the crest portion of the plywood 100, this burr or processing waste or the like is put in the hole portion 41c. Since it can escape, it can prevent that exact positioning is prevented.

The positioning stopper 42 shown in FIG. 10 is spaced apart from the continuous convex portions 42a and 42b protruding in the direction opposite to the plywood conveyance direction in the direction perpendicular to the conveyance direction, like the positioning stopper 41 in FIG. Each hole is provided with a hole 42c for accommodating burrs and processing scraps at the bottom of the recess that will be formed between the continuous protrusions 42a and 42b. However, it differs in that the tip of the convex portion of the positioning stopper 42 is chamfered.
According to the plywood conveying device having the positioning stopper 42 having such a configuration, when the convex portion of the positioning stopper 42 and the portion 100b that becomes the valley of the plywood 100 are brought into contact with each other, as shown in FIG. In addition, since a gap 42d is formed between the convex portion and the valley portion 100b, even when machining waste or the like is sandwiched between the valley portion 100b of the plywood 100 and the convex portion of the positioning stopper 42, Since it is possible to allow machining scraps and the like to escape to the gap (gap) 42d between the convex portion and the portion 100b that becomes the valley of the plywood 100, it is possible to further prevent the accurate positioning from being hindered.
Although not shown, the positioning stopper 42 may be a positioning stopper in which the tip of the convex portion is chamfered and the hole 42c is not formed.

Further, the positioning stopper in the present conveying device does not have to be a stopper provided with a convex portion protruding in the direction opposite to the plywood conveying direction, and the cross-sectional shape in a plane parallel to the surface of the plywood 100 is opposite to the conveying direction. As an example in which two or more arc portions protruding in the direction are provided in a direction orthogonal to the conveyance direction, for example, a stopper having a round bar shape as shown in FIG. 12 may be used.
This positioning stopper is composed of two round bars 43. The diameter of the round bar 43 is formed such that the outer peripheral portion and the portion that becomes the valley of the plywood can come into contact with each other.
According to the plywood conveying device having the positioning stopper 43 having such a configuration, when the plywood 100 abuts on the round bar 43 serving as the positioning stopper, as shown in FIG. The part which becomes the trough of the plywood 100 will contact | abut.
Therefore, it is possible to avoid the tip portion of the portion 100a serving as the crest of the end portion of the plywood 100 from contacting the positioning stopper 43, so that the tip portion is damaged or deformed by contact with the positioning stopper. This can be prevented. Further, according to the present configuration in which the positioning stopper itself has a round bar shape, when the positioning stopper 43 and the plywood 100 come into contact with each other, a round bar-shaped positioning stopper is formed in a portion that becomes a valley of the plywood 100. 43 is inserted, and the slopes forming the peaks and valleys at the end of the plywood 100 are brought into contact with the outer circumference of the circle for positioning, so that the plywood is transported in a state slightly deviated in the direction perpendicular to or oblique to the transport direction Even when the contact with the positioning stopper 43 is completed, the displacement of the plywood 100 during conveyance is completely corrected, and the position of the plywood 100 in the conveyance direction and the position orthogonal to the conveyance direction are Are simultaneously positioned. Furthermore, there is no possibility that processing waste or the like is caught between the positioning stopper and the plywood.
The positioning stopper is not limited as long as the slopes forming the peaks and valleys at the end of the plywood are in contact with the outer periphery of the arc portion of the positioning stopper so that positioning can be performed. The cross-sectional shape of the round bar in a flat plane may be an ellipse or a semicircle, and the round bar may have a hollow cylindrical shape at the center.

  Next, as a second embodiment, a system for transporting a plurality of plywood as described above and bonding them to each other will be described with reference to FIGS. Of the plywood placed on the two conveyors 20A and 20B facing each other shown in FIG. 14 and the like, the plywood on the conveyor 20A side will be described as a plywood 100A, and the plywood on the conveyor 20B side will be described as a plywood 100B.

FIG. 14 is a plan view showing the entire transport system in a state where the plywoods 100A and 100B are placed on two conveyors facing each other, and FIG. 15 is a side view thereof.
As shown in these drawings, this transport system includes two transport devices having the configuration shown in the first embodiment, and a press device for bonding two plywoods composed of an upper surface plate 70a and a lower surface plate 70b. 70, a second air cylinder 71 for raising and lowering the pressing device lower surface plate 70b, and a moving frame 80 for moving the pressing device 70 and the positioning stopper 60.
The positioning stopper 60 and the first air cylinder 45, as well as the pressing device 70 and the second air cylinder 71 are fixed to a moving frame 80, and the moving frame 80 has two conveyors that face each other as shown in FIG. It is installed so that it can move between 20A and 20B in the K1 direction or the K2 direction.

Note that the positioning stopper and the first air cylinder are not provided in the respective conveying devices, but are installed between the two conveyors 20A and 20B facing each other, so that one positioning stopper is used for the two conveying devices. The air cylinder is shared.
Since one positioning stopper is shared by the two conveying devices, the positioning stopper is configured as shown in FIG. That is, the positioning stopper 60 is provided with a plurality of continuous convex portions on both surfaces in the longitudinal direction, shifted by a half pitch in the longitudinal direction. Moreover, the height of the convex part becomes a structure higher than the height of the part used as the peak of the plywood edge part cut into the zigzag shape similarly to 1st embodiment, These continuous convex parts are the structure. A hole 61c for accommodating burrs and processing scraps is formed in the bottom portion of the recess that is to be formed therebetween.

As with the transport device of the first embodiment, the two transport devices are conveyors 20A and 20B other than the positioning stopper and the first air cylinder, motors (not shown) for operating the conveyors 20A and 20B, and conveyors 20A and 20B. Control device (not shown) for controlling running and stopping, guides 10A and 10B for determining an approximate placement position of the plywoods 100A and 100B, and feed detection for measuring the moving distance of the plywood and detecting the stop of the plywood Each has rolls 30A and 30B.
These two conveying devices include a positioning stopper 60, a first air cylinder 45 that raises and lowers the positioning stopper 60, a preheated press device 70 including a press device upper surface plate 70a and a lower surface plate 70b, and A second air cylinder 71 that raises and lowers the lower surface plate 70b of the press device 70 and a moving frame 80 that moves them to the left and right are sandwiched between them, and the other transport device on the lower side in the transport direction of the conveyor of one transport device. Are installed so that they are positioned relative to each other.
In addition, the plywood 100A and 100B are cut into a zigzag shape in a direction perpendicular to the conveyance direction of the plywood, and both ends on the lower side and the upper side in the conveyance direction of the plywood are scarf-shaped, respectively. Description will be made assuming that an adhesive is applied to the lower end portion in the transport direction of either one of the plywoods 100B by a known method.

Hereinafter, a flow in which a plurality of plywoods are transported and bonded together by this transport system will be described.
First, the plywoods 100A and 100B are placed on the conveyors 20A and 20B along the guides, respectively. On the plywood 100A and 100B placed on the conveyor, feed detection rolls 30A and 30B are respectively installed in such a manner that the roll portions abut against the surfaces of the plywood 100A and 100B. Positioning stoppers 60 are installed on the lower side in the K1 direction, which is the conveying direction of the plywood 100A, and on the lower side in the K2 direction, which is the conveying direction of the plywood 100B (FIGS. 14 and 15).

  When the motor is driven, the plywood 100A is first conveyed in the K1 direction by the conveyor 20A. As a result, the lower end of the plywood 100A in the conveying direction comes into contact with the convex portion of the positioning stopper 60 protruding toward the plywood 100A, thereby positioning the plywood 100A. At the same time, the movement of the plywood 100A is interrupted by the positioning stopper 60 and stopped (FIG. 17). When the movement of the plywood 100A is stopped, the rotation of the roll portion of the feed detection roll 30A is stopped, and the rotation stop signal is immediately sent to the control device, and the control device controls to stop the motor of the conveyor 20A. The positioning stopper 60 causes the plywood 100A to be completely corrected for misalignment during conveyance of the plywood, as in the first embodiment, and the position of the plywood 100A in the conveyance direction and the position in the direction orthogonal to the conveyance direction simultaneously. Positioned. In addition, when the convex portion of the positioning stopper 60 and the portion that becomes the valley of the plywood 100A come into contact with each other, the height of the convex portion is the peak of the end portion of the plywood 100A that has been cut into a zigzag shape. Since the configuration is higher than the height, the tip of the portion that becomes the peak does not come into contact with the positioning stopper 60, and a good adhesion surface can be obtained. In addition, since the positioning stopper 60 has the hole portion 61c, the processing accuracy of the portion that becomes the crest of the plywood 100A is poor, and a burr is formed near the apex, or the continuous protrusion in the positioning stopper 60 is formed. Even when a processing waste or the like is sandwiched between a concave portion to be formed between the portions and a portion to be a mountain of the plywood 100A, the positioning is accurately performed.

  When the positioning of the plywood 100A is completed, the moving frame 80 adheres the end of the plywood 100A and the end of the plywood 100B by the moving frame 80 under the control of the control device. Move to the most suitable position. Specifically, the moving frame 80 moves the positioning stopper 60 and the pressing device 70 in the K1 direction of FIG. 18 to a place where the lower end of the plywood 100A in the conveying direction is at the center of the pressing device 70.

When the movement of the positioning stopper 60 and the pressing device 70 is completed, the control device controls to drive the motor of the conveyor 20B on the plywood 100B side. As a result, when the plywood 100B is conveyed in the K2 direction by the conveyor 20B, the lower end of the plywood 100B in the conveying direction comes into contact with the convex portion of the positioning stopper 60 protruding toward the plywood 100B, thereby positioning the plywood 100B. At the same time, the movement of the plywood 100B is interrupted by the positioning stopper 60 and stopped (FIG. 18). When the movement of the plywood 100B is stopped, the rotation of the roll portion of the feed detection roll 30B is stopped, the rotation stop signal is immediately sent to the control device, and the control mechanism controls the motor of the conveyor 20B to stop.
Similarly to the first embodiment, the plywood 100B is completely corrected for the displacement during the conveyance of the plywood by the positioning stopper 60, and the position in the conveyance direction of the plywood 100B and the position in the direction orthogonal to the conveyance direction are simultaneously set. Positioned.

As shown in FIG. 16, the positioning stopper 60 includes a plurality of continuous convex portions on both sides in the longitudinal direction that are shifted by a half pitch in the longitudinal direction. Therefore, the positions of the plywoods 100 </ b> A and 100 </ b> B that have been positioned with respect to each other. As shown in FIG. 19, the relationship between the end crest of the plywood 100B and the end trough of the plywood 100A is the end trough of the plywood 100B and the end of the plywood 100A. The portions that become the crests of the portions are positioned in a state where they are opposed to each other with a certain interval determined according to the thickness of the plywood.
In addition, when the convex portion of the positioning stopper 60 and the portion that becomes the valley of the plywood 100B come into contact with each other, the height of the convex portion is the peak of the end portion of the plywood 100B that has been cut into a zigzag shape. Since the configuration is higher than the height, the tip of the portion that becomes the peak does not come into contact with the positioning stopper 60, and a good adhesion surface can be obtained. Further, since the positioning stopper 60 has the hole portion 61c, the processing accuracy of the crest portion of the plywood 100B is poor, and a burr is formed in the vicinity of the apex, or a continuous protrusion in the positioning stopper 60 is formed. Even when a processing waste or the like is sandwiched between a concave portion to be formed between the portions and a portion to be a mountain of the plywood 100B, the positioning is accurately performed.

When the motor of the conveyor 20B stops, the first air cylinder 45 lowers the positioning stopper 60 under the control of the control device. The controller starts driving the plywood 100B in the K2 direction by the conveyor 20B by driving the motor again after the positioning stopper 60 is lowered.
Since both the plywood 100A and 100B are already positioned in a state where they are opposed to each other with a certain interval as shown in FIG. 19 by the above process, the plywood 100B is moved in the K2 direction by the distance of the interval. As shown in FIG. 20, the plywood 100A and the plywood 100B have a portion where the end crest of the plywood 100B becomes a trough at the end of the plywood 100A, and a portion which becomes a trough at the end of the plywood 100B. The plywood 100A is exactly aligned with the end portion of the plywood 100A. The moving distance of the plywood 100B is measured by the feed detection roll 30B, but the distance between the plywood 100A and the plywood 100B positioned relative to each other is a fixed distance determined according to the thickness of the plywood ( 19), when the feed detection roll 30B detects that the plywood 100B has moved in the direction of the constant distance K2, the control device controls to stop driving the motor of the conveyor 20B (FIG. 21).

  When the drive of the motor of the conveyor 20B stops, the second air cylinder 71 raises the lower surface plate 70b of the press device 70 under the control of the control device. Since the adhesive is applied to the end of the plywood 100A or 100B by a known method in advance, the end of the plywood 100A and 100B is located between the upper platen 70a and the upper platen 70a as the presser lower platen 70b rises. And bonded by the pressure and heat (FIG. 22).

  After the plywood 100A and 100B are bonded together by the above process, the press apparatus lower surface plate 70b is lowered again by the second air cylinder 71, and the bonded plywood 100A and 100B are sent out in the K2 direction by the conveyor 20A ( FIG. 23). The movement distance of the fed plywood 100A and 100B is measured by the feed detection roll 30A, and when the feed detection roll 30A measures that it has moved a predetermined distance, the motor of the conveyor 20A stops. Thus, the plywood 100A and 100B sent out will be in the state mounted on the conveyor 20A like the plywood 100A at the beginning of this process. A new plywood is placed on the other conveyor 20B in the same manner as the plywood 100B at the beginning of this process. By repeating the steps described above from this state, the plywood can be continuously joined one after another.
