In addition, the promotional surface 12 is bent orthogonally from the pre-folded outer wall 11, and both ends in the longitudinal direction span the upper end of the side wall 16 as shown in FIG. The inner wall 13 and the bottom ground surface 14 are maintained in a horizontal state.

In addition, the pushing plate 145 is located above the bottom ground surface 14, and is in a raised state according to the initial position of the rod 141a.

In the above state, while the rod 141a is lowered by the driving of the lifting cylinder 141, the pushing plate 145 is lowered, and the end of the inclined surface 144a of the pushing plate 145 is bottomed as shown in FIG. The bottom ground surface 14 is folded in the left direction on the drawing while in contact with the support surface 14.

Subsequently, when the shaft 20 rotates in the right direction in the drawing by the driving source (not shown) in the state as shown in FIG. 7C, the rotating block 110 is rotated together with the rotation of the shaft 20.

At this time, the inclined surface 144a of the pushing plate 145 is continuously folding the floor ground surface 14, and at the same time the pressure plate 124 of the variable means 120 also makes contact with the inner wall 13 and the inner wall 13 ) To the left in the drawing.

In addition, when the rotation of the shaft 20 is continuously performed, the distal end portion of the bottom ground surface 14 is in contact with the bottom surface of the paper sheet 10 as shown in FIG. 7 (d), and the inner wall 13 is It is further folded by the pressure plate 124.

In the above state, the pushing plate 145 is returned to the initial position by driving the lifting cylinder 141 as shown in FIG. Here, the reason for returning the pushing plate 145 is that the end of the bottom ground surface 14 is in contact with the bottom surface in the state of FIG. This is because interference between the inner wall 13 and the pushing plate 145 occurs, and above all, the return of the pushing plate 145 cannot be achieved.

Finally, as shown in FIG. 7F, when the rotation of the shaft 20 is completed at 90 degrees in the drawing, the inner wall 13 maintains a vertical folded state perpendicular to the promotional surface 12, and the inner wall ( The bottom ground surface 14 connected with 13 is in complete contact with the bottom surface of the paper sheet 10 to complete molding of the head portion 15.

Then, when the molding of the head portion 15 is completed, the molding unit 100 returns to the initial state by the reverse rotation of the shaft 20, and waits for the folding of the next paper plate 10.

As described above, the head portion forming apparatus of the paper sheet member having the variable function of the present invention has a width of the head portion formed according to the size of the paper sheet material, while stably forming the head portion in forming the paper box of the paper sheet material. Even if this change is made, the change of the molding unit is automatically made by the changed width, so that it is not necessary to replace a separate molding unit as in the prior art, thereby having an excellent effect of preventing a defect or damage of the product due to the replacement failure.

As described above, the head forming apparatus of the paper sheet having a variable function of the present invention has been described by the preferred embodiment and the accompanying drawings, which are intended to help the understanding of the present invention and are not intended to limit the technical scope of the present invention. Of course.

That is, those skilled in the art without departing from the technical gist of the present invention can be variously modified or modified, as well as such changes or modifications, the technical scope of the present invention in the interpretation of the claims. It is hard to say that I am within.
