The driving unit 800 has a shaft 840 having a plurality of guide grooves 841 formed along a longitudinal outer circumferential surface thereof, and an inner circumference thereof is coupled to an outer circumference of the shaft 840, and an outer circumference thereof is inserted into the horizontal plate foldable part 500. A ball spline 850 which allows the horizontal plate foldable part 500 to rotate and axially slide relative to the shaft 840, and a bracket provided at both sides of the shaft 840 to support the shaft 840 ( 830 and a motor 810 and a reducer 820 coupled to one end of the shaft 840 to decelerate and rotate the shaft 850.

The motor 810 and the reducer 820 are coupled to the shaft to decelerate the rotational force generated by the motor by a certain amount through the reducer and transmit the result to the shaft.

The bracket 830 has a plate shape and is bearing-coupled to the shaft 840.

In addition, although not shown in the drawings, the bracket 830 is fixedly supported on a frame (not shown) constituting the skeleton of the present invention.

The shaft 840 is a stepped rod having an outer circumferential surface along the longitudinal direction, and respective components are coupled to the stepped portions.

In addition, a plurality of guide grooves 841 are formed along an outer circumferential surface at a predetermined length of the central portion of the shaft 840, and a ball of a ball spline which will be described later is inserted, and the ball moves along the guide groove when the shaft slides in the axial direction. When rotating, the ball is caught in the guide groove so that the horizontal plate foldable portion 500 coupled to the ball spline can rotate like an axis.

The ball spline 850 has a ball housing 851 having a space 851a formed therein, and a horizontal plate fold portion which is inserted into the space 851a and slides along the guide groove 841 or is defective such as an axis. It consists of a ball 852 that makes it rotatable.

That is, the ball spline 850 is configured to seat a plurality of balls 852 along the guide groove 841 formed in the shaft 840, the housing 511 to which the ball spline 850 is coupled is the shaft The ball 852 moves along the guide groove 841 when the direction is moved, but when the shaft 840 rotates, the ball 852 is caught in the guide groove 841 so that the housing 511 rotates the shaft 840. And rotates at the same time.

In the coupling relationship of the present invention, a pair of ball splines 850 is first inserted into the shaft 840 such that the balls 852 of the ball spline 850 are inserted into the guide groove 841 of the shaft 840.

Next, the housing 511 is inserted into the shaft 840 such that the outer circumferential surface of the ball spline 850 is inserted into and coupled to the ball spline insertion hole 511b in the housing 511. At this time, it is preferable that the housing 511 maintains a constant distance from each other.

Next, the wide side of the spring 536 is inserted into the support groove 514 formed inside the fixing stand 512 formed in the housing 511 and the narrow side of the spring 536 has the unevenness 535a formed therein. The binding block 535 is inserted into the binding block 535 to be supported on the other side.

Then, the binding block 523 pushed by the elasticity of the spring 536 by inserting the lifting platform 521 into the guide hole 513 of the fixing table 512 so that the unevenness 523 of the lifting platform 521 faces the unevenness 535a. 535 is in close contact with the platform 521 so that the respective unevenness (523,535a) is in close contact.

Next, after inserting the support block 531 of the "C" shape to surround the fixing stand 512 and insert the guide ring 538 into the guide ring insertion hole 534 formed in the support block 531. Guide ring 538 is positioned in lifting slot 524 of platform 521.

In this state, the movable bar 537 is inserted into the inner circumferential surface of the guide ring 538 to insert a screw (not shown) formed on the outer circumferential surface of one end of the movable bar 537 to insert the movable bar 535b of the binding block 535. The movable bar 537 is axially slid and pressurized by the binding block 535 by being screwed on.

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, the width is adjusted according to the entered width and the horizontal inner wall and the horizontal outer wall through the rotation operation in the state of adjusting the height according to the height of the entered paper board This can be folded to overlap.

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

As shown in FIG. 9, the horizontal plate foldable part 500 and the locking step insertion part 600 are arranged in a direction opposite to each other based on an axis in accordance with the width l of the paper sheet 1 entering as described above. The width adjusting means 700 is operated to slide.

After adjusting the width to the width of the paper sheet 1, as shown in FIG. 10, 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. 11, the lifting slot 524 is guided to the guide ring 538 by pressing the lower side of the platform 521 or by pulling the pressure bar 527 coupled to the upper end of the platform. 513 is raised along 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 (4b) of the paper plate (1) located adjacent to the pressing unit.

Next, as shown in FIG. 12, 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 compressed 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 13 by operating the motor provided at the end of the shaft 840 to rotate the shaft 840 in the 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 rotates the platform 521 of the horizontal plate folding part 500 coupled to the housing, thereby folding the horizontal inner wall 4b adjacent to the platform 521 so that the horizontal axis is already folded. It is in a state perpendicular to the outer wall 4a.

At this time, since the locking jaw insertion part 600 is rotatably coupled to the housing 511 by the bearing housing 650, the locking jaw insertion part can maintain the correct position even if the housing rotates by the shaft.

After the folding of the horizontal inner wall overlaps the horizontal outer wall, the motor 810 is driven again to reverse the rotation of the shaft 840 so that the horizontal plate folding part 500 is rotated so as to wait for the folding of the next paper sheet. do.

Thus, by automatically folding the horizontal plate using the pressure bar adjusted according to the height of the horizontal plate, it is possible to reduce the time and cost required when folding the paper plate, as well as to increase the precision of forming the paper plate. Double wall paper box molding 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.
