According to the present invention, the cross beam 34 is installed to be able to move up and down so as to approach the spike 15 and engage the paper. The cross beam 34 is installed to be capable of vertical movement in a direction perpendicular to the main conveyor 14, that is, in a width direction of the main body 10. When the cross beam 34 is raised, it is engaged with the lower end of the needle of the spike 15 to prevent the separation of the base paper.

In addition, according to the present invention, a supporting rod 36 having a rack tooth form 36a is provided to support the cross beam 34 so as to be movable back and forth. The supporting rod 36 is slidably installed at both ends in the axial direction, and the cross beam 34 is fixed on the supporting rod 36 arranged in the width direction of the main body 10. The rack tooth form 36a formed in the middle of the supporting rod 36 is revealed in detail in FIG.

In addition, according to the present invention, the adjustment lever 42 rotated to move forward and backward on the cross beam 34 on the support rod 36 is provided via the control plate 32 on one side of the cross beam 34. The adjusting plate 32 is fixed to the inner side of the main body 10 in the width direction, and the adjusting lever 42 is rotatably installed on the adjusting plate 32. The adjustment lever 42 allows the vertical motion of the crossbeam 34 to be interrupted in accordance with the position change as will be described later.

In addition, according to the present invention is provided with a swing mechanism 52 for contacting at the set end position of the cross beam 34 to provide a vertical movement force. The swing mechanism 52 is a reciprocating rotational motion (crank motion) by providing an operating force to raise and engage the crossbeam 34 in accordance with the timing at which the spike 15 of the main conveyor 14 passes above the crossbeam 34. A separate motor may be used to perform), but it is advantageous to mechanically connect with the main conveyor 14.

The control lever 42 of the present invention is provided with an elastic piece 46 on one side to be selectively seated in the groove (32a) formed at two points of the adjustment plate 32, by the swing mechanism 52 according to the seating position The vertical motion of the crossbeam 34 is to be interrupted. The control plate 32 is provided with a groove 32a at two points in the rotational position of the control lever 42. The groove 32a may be a through groove. The control lever 42 is provided with an elastic piece 46 so as to stop in the groove 32a. The elastic piece 46 can use a sphere or pin supported by a spring. When the pinion gear 44 rotates due to the positional change of the adjustment lever 42, the support beam 36 having the rack tooth type 36a moves forward or backward and the cross beam 34 also interlocks. The roller 54 of the oscillation mechanism 52 maintains contact with the crossbeam 34 or maintains separation in accordance with the forward or backward movement of the crossbeam 34. Contact by the roller 54 of the rocking mechanism 52 is made through the pressing piece 34b formed in the lower end of the crossbeam 34. As shown in FIG.

In operation, when the corrugated sheet of paper is put into the loading platform 12 of the main body 10, the main conveyor 14 rotates, the spike 15 takes a sheet of paper and conveys it, and the first box cuts into a developed box shape. After the process and the second step of performing a partial stripping to reach the third step for separating and discharging the semi-finished product from the raw paper. If the control lever 42 is placed in the reverse state (manual mode), the cross beam 34 does not come into contact with the swinging mechanism 52, and thus does not rise. Fall all. In this case, the process of separating residues and semi-finished products from dropped papers must be done manually. However, when the control lever 42 rotates to the advanced state (automatic mode), the cross beam 34 moves horizontally and contacts the swing mechanism 52 so that the upward movement is periodically performed. Since the discharge cylinder 28 operates while the cross beam 34 is supported to support the paper, only the semi-finished product is separated and the residual land continues to move and is collected on a separate auxiliary conveyor 64 at the discharge port 60. The dropped semi-finished products are discharged in a stacked state on the unloading platform 18 descending by one step.
