2. Description of the Related Art Conventionally, in the production of laminated materials such as plywood, an apparatus described in Japanese Patent Publication No. 49-8245 is an example of an apparatus for laminating a glued veneer and a laminated veneer. As shown in FIG. 8, a conveyer 103 capable of running and stopping is provided on the carry-out side of a spreader 101 in which each roll rotates as shown by an arrow to apply an adhesive to the front and back surfaces of a single plate. On the carry-out side of the conveyor 103, a large-diameter pulley 105 that is driven to rotate in the direction of the arrow is disposed, and pulleys 107 and 1 provided at positions shown in the drawing are provided.
09 and the belt 111, and the belt 111 is running at the same speed as the conveyor 103 as shown by the arrow. Further, a small-diameter pulley 113, a driving pulley 115, and a pulley 117 are provided at positions shown in the drawing, and a belt 121 is stretched over the belt 121, and the belt 121 runs at the same speed as the belt 111 in the direction of the arrow. In the above device, the belt 1
When the two veneers 125 and 127 laid on top of each other with the lower end portions in the transport direction of the two aligned with each other are placed on the belt 121 and transported, the belt 1
Two single plates 125 and 127 by 11, bell and 121
Is transported upward while being pinched, and reaches above the large-diameter pulley 105 in a reversed state. On the other hand, spreader 101
The intermediate plate 123 coated with the adhesive on its front and back surfaces is conveyed onto the large-diameter pulley 105 by the conveyor 103.
23 and the veneers 125, 127
The traveling / stop of the conveyor 103 is controlled such that the lower end of the conveyor 103 in the transport direction simultaneously reaches the same position above the large-diameter pulley 105. Therefore, the intermediate plates 123 coated with the adhesive on the single plates 125 and 127 are superimposed as shown by B, and are manually or conventionally deposited on a deposition table 131 provided on the lower side in the transport direction of the belt 111. It is sequentially deposited as indicated by A by the apparatus. In the group of veneers thus deposited, the upper and lower three veneers sandwiching the middle plate coated with the adhesive are taken out as a set, and are heated and pressed by a hot press (not shown) to cure the adhesive. One plywood is manufactured.

[0003]

In the above apparatus, a veneer 125,
Since the belt 111 and the belt 121 travel at the same speed when the 127 is transported along the large-diameter pulley 105 while being sandwiched between the belt 111 and the bell 121, the veneers 125 and 127 also have the same travel distance. Become. But veneer 12
5 and 127 naturally have a thickness, and the distance from the rotation center of the large-diameter pulley 105 to the position where the single plates 125 and 127 pass, that is, the radius is different. Becomes Therefore, as described above, both veneers 125, 12
If the moving distances of the veneers 7 are the same, the veneer 125 traveling inside the large-diameter pulley 105 moves ahead of the veneer 127 at the lower end of the veneers 127 in the transport direction. The amount of the deviation depends on the warp of the veneer, etc.
Adjusting the speed of the bell and the 121 does not eliminate the deviation. If such a shift occurs, a problem such as a failure of the manufactured plywood occurs.

As shown in FIG. 1, a servo motor 3 is provided on an unloading side of a spreader 1 in which rolls 1a and 1b rotate as shown by arrows and apply adhesive to the front and back surfaces of a veneer. A number of rolls 5 are provided so as to be rotatable and stopped in the direction of the arrow. A diffuse reflection type photoelectric switch (hereinafter, referred to as a photoelectric switch) 7 for detecting a single plate is provided in the vicinity of a lower side of a plurality of rolls 5 in a single plate transport direction described later. Also, in order to constitute an example of the third transport body,
A plurality of pulleys 9 are provided at the same height in the vertical direction as the number of rolls 5 at intervals in a direction orthogonal to a running direction of a belt 13 described later, and a plurality of pulleys 11 are provided diagonally below.

Further, a plurality of arc-shaped support bases 15 as shown in the figure are provided diagonally below the pulley 11 at intervals in a direction orthogonal to a running direction of a belt 21 to be described later, so as to constitute an example of a second transport body. On the outer side of the support table 15, that is, on the left side in the figure, there are provided a large number of driven and rotatable small-diameter rolls (hereinafter, referred to as rollers) 14 at intervals in the running direction of the belt 21. The imaginary line connecting the abutting portions is configured to be in the shape of a circular arc projecting obliquely upward. Further, a pulley 16 and a pulley 17 at a height slightly lower than the pulley 16 in the vertical direction are provided below the support base 15, and a plurality of belt-like belts 18 are stretched over the belt 13 like the belt 13. Support table 1
5 and a plurality of pulleys 19 and 2 opposed to the upper end and the lower end of the pulley 5.
0, and the belts 21 are wrapped around the support bases 15, respectively. When the belts 21 are pressed against the respective contact portions of the rollers 14, the belts 21 follow each other, and have an arc shape that is obliquely upward and convex as shown in the figure. Become.

On the other hand, pulleys 23 and 24 are provided at predetermined positions in a direction away from the roll group 5 at the same height in the vertical direction as the pulley 9, and a plurality of belts 25 are provided between the pulleys 23 and 24 in the same manner as the belt 13. Over. Further, in order to detect a veneer conveyed by the belt 13 between the adjacent belts 13, a photoelectric switch 27 is provided as shown. The pulleys 9, 16, 19, and 23 are freely rotatable and stopped simultaneously by a servomotor 29. During rotation, the belts 13, 18, 21 and 25 run at the same speed in the direction of the arrow, and the pulleys 11 , 17, 20 and 24 are driven to rotate. Further, at the position corresponding to the unloading side of the plurality of rolls 5 and between the plurality of adjacent belts 13, the belt 5 is conveyed by the plurality of rolls 5 and the belts 13 as shown by a solid line and having a rotation center. A stopper 33 is provided between the position where the transfer of each veneer is prevented and the position where the transfer of the veneer is not obstructed, as indicated by the dotted line, by the operating member 31 such as a cylinder. The angle at which the stopper 33 bends is again adjusted by the roller 5 and the belt 13 from the position where the original plates 39 and 41 and the intermediate plate 43 come into contact with the stopper 33 and stop, respectively, as shown in FIG. By being transported, the veneer veneer 3
It is determined that the distances to be conveyed to the position where the sheets 9 and 41 and the intermediate plate veneer 43 are overlapped are the same. Further, a controller 35 is provided which controls the operations of the servomotor 3, the servomotor 29 and the operating member 31 in accordance with signals from the photoelectric switches 7 and 27 as described later. On the other hand, pulley 23
On the lower side, a stacking table 37 is arranged, and as described later, the veneer conveyed by the belt 25 is manually deposited with the edges of the veneer aligned.

In the device configured as described above, the veneers are superposed as follows. In FIG. 1, each roll 1a, 1b of the spreader 1 rotates in the direction of the arrow,
The operation of the servomotor 3 rotates a large number of rolls 5 in the direction of the arrow, and the operation of the servomotor 29 causes the pulleys 9, 16, 19, and 23 to rotate simultaneously, that is, the belts 13, 1
8, 21 and 25 are traveling in the direction of the arrow, and furthermore, in the initial state where the stopper 33 waits at the position indicated by the solid line,
On the belt 18, two original plates 39, 41 in a state in which the lower edges of the belt 18 in the running direction (hereinafter, referred to as leading edges) are aligned are manually placed. Then, the original veneers 39 and 41 are conveyed by the belt 18, and at the location of the roller support 15, as shown in FIG.
4 are conveyed obliquely upward through the arc-shaped passage while being pressed against the belt 4 sequentially, and then conveyed onto the belt 13. When the original plates 39 and 41 are detected by the photoelectric switch 27 on the belt 13, the controller 35 having received the detection signal sends the original plate to the stopper 33 which stands by at a predetermined minute time, that is, the standby position. After a lapse of a sufficient minute time for the leading edges of the veneer veneers 39 and 41 to hit, a stop signal is issued to the servomotor 29, and the pulleys 9, 16, 19 and 23 stop, that is, as shown in FIG. 18, 21 and 25 stop running, and wait in a state where the leading edges of the original plates 39 and 41 have hit the stopper 33.

On the other hand, when the middle plate veneer 43 is manually inserted into the spreader 1, the adhesive is applied to the front and back surfaces of the middle plate veneer 43, and then, as shown in FIG. It is transported rightward. When the photoelectric switch 7 detects the middle plate single plate 43 on the plurality of rolls 5, the controller 35 receiving the signal receives a signal after a predetermined short period of time, that is, the controller 35 stops moving to the stopper 33 waiting at the above position. After a lapse of a minute time sufficient for the leading edge of the plate veneer 43 to hit, a stop signal is issued to the servomotor 3 and a number of rolls 5 stop running, as shown in FIG. It waits in a state where the leading edge of the veneer plate 43 hits the stopper 33. Next, the controller 35 issues an operation signal to the actuating member 31 after a lapse of a predetermined minute time from the completion of issuing the stop signal to the servomotors 3 and 29, and turns the stopper 33 to the position shown by the dotted line. Move. Next, the controller 35 sends an operation signal to the servo motors 3 and 29 after a predetermined minute time has elapsed, and the many rollers 5 and the pulleys 9, 16, 19, and 23 rotate. Let me do. The original veneers 39, 41 and the intermediate veneer 43 are conveyed again by the belt 13 and the many rolls 5, respectively, and conveyed by the same distance from the position where they hit the stopper 7. As shown in FIG. The intermediate plate veneer 43 is superimposed on the original plate veneers 39 and 41 on the base plate 13 with their leading edges aligned. A single veneer group composed of the superimposed veneer veneers 39 and 41 and the intermediate veneer veneer 43 is conveyed by the belt 25 via the belt 13 and
When the position 3 is reached, as shown in FIG.
The sets are integrally deposited on the deposition table 37.

Next, by the same operation as described above, the two veneer veneers and one intermediate veneer are overlaid so that the leading edges thereof are aligned, and these three veneers are also manually set. Board,
A set of three veneers 39 already deposited on the deposition table 37,
The top edges of the veneers in different sets are aligned on 41 and 43, that is, the veneers on the stacking table 37 are all stacked with the top edges aligned with each other. By repeating the above operation, a single plate is deposited.

As described above, in the embodiment, two superposed single plates are applied to a large number of rollers 5 which are one of the first conveying members for conveying the pasted single plates. In order to convey from the position on the upper side in the conveying direction and below the plurality of rollers 5 toward the lower end in the conveying direction of the rollers 5, the rollers 14 and the belt 21, which are one of the second conveying members, Since the belt 13 and the like are provided, the two laminated veneers are not largely displaced from each other. That is, 2
Since the veneer laminated on the sheets is conveyed obliquely upward from below the spreader 1 toward the unloading side of the spreader 1,
Compared to the large-diameter pulley 105 in the conventional apparatus, the single-sheet conveying path is part of an arc of a virtual circle having a large radius or substantially linear. Therefore, suppose that the transport path of the two veneers is part of the arc of a virtual circle having a large radius, and the distance from the center of rotation of the virtual circle to the position where the two veneers each pass differs. However, the circumferential lengths at the respective positions are almost the same, and the two veneers are hardly displaced.

Next, a modified example of the present invention will be described. 1. As a part of the second transporting body that transports the two laminated veneers, the roller 14 and the support 1
5 and the belt 21 and the like, an arc-shaped single-plate conveyance path projecting obliquely upward is formed, but as shown in FIG. An arc-shaped single-plate transport path E may be formed.

2. In the above embodiment, both the veneer 43 conveyed by the roll 5 and the two veneers 39 and 41 conveyed by the belt 13 are brought into contact with the stopper 33.
A veneer in which the transport direction is orthogonal to the fiber direction may bend when it comes into contact with the stopper, and accurate positioning may not be possible. Therefore, a configuration may be adopted in which only the veneer whose veneer transport direction is the fiber direction is brought into contact with the stopper. That is, in the above-described embodiment, since the intermediate veneer 43 coated with the adhesive is usually conveyed in the fiber direction, it can abut only on the veneer 43 conveyed by the roll 5 as shown by the solid line in FIG. 3 that is rotatable between the position shown in FIG.
4 is provided. On the other hand, a detector 28 for detecting that the two conveyed veneers 39 and 41 have reached the same position as that shown in FIG. 3 is provided on the belt 13 side.
Except for the stopper 34 and the detector 28, the configuration is the same as that of the above-described embodiment, and each member is operated as follows. The veneers 39 and 41 are conveyed onto the belt 13 via the belts 18 and 21 in the same manner as in the above-described embodiment, and when detected by the detector 28, the belts 18, 21 and 13 are stopped, and FIG. Wait at the indicated position. Similarly, when the single plate 43 coated with the adhesive and conveyed by the roll 5 is detected by the photoelectric switch 7 in a state where the stopper 34 is in a standby state at the position indicated by the solid line in FIG.
After the roller 5 is positioned by contact with the stopper 34, the roll 5 stops running. Next, the stopper 34 is rotated to the position shown by the dotted line, and then the roll 5 and the pulleys 9 and 1 are rotated.
By rotating 6, 19 and 23, the single plate 43 for the intermediate plate is superimposed on the single plates 39 and 41 for the original plate on the belt 13 with the leading edges aligned. The single plate 43
When positioning the single plate 4, the stopper 34 is set in standby at the position indicated by the dotted line in FIG.
When 3 is detected by the photoelectric switch 7, the traveling of the roll 5 may be stopped first, and then the stopper 34 may be rotated down to the position shown by the solid line in FIG.

3. In the above embodiment, the stoppers 33 are used to stop the single plates conveyed by the multiple rolls 5 and the belt 13, for example, the single plate 43 for the middle plate or the single plates 39, 41 for the original plates at predetermined positions. However, instead of using the stopper 33, the photoelectric switch 7 or 27 may be configured to stop each of the plurality of rolls 5 or the belts 13 with a signal for detecting each single plate. 4. Means for superimposing the single plate 43 for the intermediate plate conveyed by the large number of rolls 5 as the first transfer member on the two single plates 39 and 41 for the original plate are configured as follows. Is also good. In other words, the rollers 5 on the lower side in the transport direction of the large number of rolls 5 are removed, and both ends in the direction orthogonal to the transport direction of the intermediate plate veneer 43 are supported, and two rods continuous in the transport direction are supported. The body is provided, and the intermediate plate veneer 43 is stopped and waited at a predetermined position in the bar state. On the other hand, by stopping the belt 13, the veneer veneers 39, 41 are stopped below the veneer veneer 43 supported by the rods, and then the two rods are rapidly moved away from each other. Thereby, the veneer veneer 43 may be dropped on the veneer veneers 39, 41 and overlapped.

[0021]

As described above, according to the present invention, the transfer path of the second transfer member for transferring a plurality of stacked veneers is partially or substantially linearly formed by a virtual circle having a large radius. Therefore, the laminated veneers are hardly displaced. Therefore, the manufactured laminated material such as plywood does not become defective.
