By using the cylinder coupling hole (612a) is coupled to the cylinder and the bolt (not shown).

That is, by positioning the cylinder in a state supported by the guide rail between the fixing bracket 610 and the guide block 630 to allow the guide block 630 to move axially sliding through the operation of the cylinder 620. As a result, the housing 511 connected to the bearing housing can axially slide.

Next, the bracket 830 is inserted into and fixed to both ends of the shaft 840 so that the shaft can be rotated by bearings, and then the reducer 820 connected to the motor 810 is coupled to one end of the shaft to connect the shaft to the shaft. It can be rotated.

When the present invention coupled as described above enters the folded state of the vertical plate of the paper board material to adjust the width to enter the width and fold the horizontal inner wall through the rotation operation in the state adjusted the height to the height of the entered paper board material By inserting the locking step formed in the horizontal inner wall into the binding groove is to allow the vertical plate and the horizontal plate to be mutually supported by the locking step.

Hereinafter, with reference to the accompanying drawings will be described the operating state of the present invention.

As shown in FIG. 13, the horizontal plate foldable part 500 and the locking step insertion part 600 are arranged in directions opposite to each other based on an axis in accordance with the width l of the paper sheet 1 entering as described above.

After adjusting the width according to the width of the paper sheet 1, as shown in FIG. 14, the movable bar 537 is pushed in the direction of the axis 840 so that the movable bar 537 follows the guide ring 538. Sliding the binding block 535 coupled to the end to compress the spring (536) holding the binding block 535, the concave and convex 535a of the binding block 535 is uneven 523 of the platform 521 Depart from

Next, as shown in FIG. 15, the lifting slot 524 is guided to the guide ring 538 by pressing the lower side of the platform 521 or pulling the pressure bar 527 coupled to the upper end of the platform. 513 is raised in the height (H) direction so that the upper end of the pressing unit 527 is positioned on the horizontal line with the upper end of the horizontal inner wall (4c) of the paper plate 1 positioned adjacent to the pressing unit.

Next, as shown in FIG. 16, when the pressing force of the movable bar 537 in the state in which the binding block 535 is pressed is released, the compressive force of the spring 536 in the compressed state by the binding block 535 acts. The binding block 535 is moved to the lifting table 521 side in the raised state, the moving binding block 535 is engaged with the unevenness 523 formed on the lifting platform 521 is engaged with the unevenness 523 formed on the lifting table 521 Fix 521.

Next, after adjusting to the width and height of the paper sheet entered as described above, as shown in Figure 17 by operating the motor provided at the end of the shaft 840 to rotate the shaft 840 in a decelerated state To rotate the housing 511 associated with the shaft 840. At this time, since the guide groove 841 formed in the ball 852 and the shaft 840 of the ball spline provided therein is in close contact with the housing 511, the rotational force of the shaft is transmitted to the housing by the ball and the guide groove. .

In this state, the rotating shaft 840 folds the horizontal inner wall 4c adjacent to the platform 521 by rotating the platform 521 of the horizontal plate folding part 500 coupled to the housing 511. The horizontal outer wall 4a in a pre-folded state is in a horizontal direction in the vertical direction.

At this time, since the locking jaw inserting part 600 is rotatably coupled to the housing 511 by the bearing housing 650, even if the housing 511 rotates by the shaft, the locking jaw inserting part 600 is in the correct position. Will be able to maintain.

Next, as shown in FIG. 18, the rod 621 is operated by the cylinder 620 of the engaging jaw insertion part 600 while the horizontal inner wall 4c is folded by the lifting platform 521. The guide block 630 coupled to the rod 621 slides along the guide rail 640 and is inserted into the ball spline 850 inside the housing 511 coupled to the shaft 840. The provided balls 852 move in the axial direction along the guide groove 841 of the shaft 840, and the lifting table 521 coupled to the housing 511 and the pressing table 527 coupled to the ends of the lifting platform 521. The protrusion piece 528 of the c) is pressed into the engaging groove 3d formed in the vertical inner wall 3c by pressing the locking jaw 4d of the horizontal inner wall 4c.

After the insertion is completed, the cylinder 620 is operated again to move the rod 621 to the opposite side of the moving direction to move the protruding piece 528 from the binding groove and the detached protruding piece 528 to the housing 511 side. Rotate to restore the original position and wait for folding of the next sheet of paper.

In this way, it is possible to automatically carry out the folding of the horizontal plate and the insertion of the locking step, thereby reducing the time and cost required for folding the paper plate, as well as increasing the precision of forming the paper plate. Can be realized.

The present invention is not limited by the embodiments described above, and various changes and modifications can be made by those skilled in the art, which are included in the spirit and scope of the present invention as defined in the appended claims.
