Therefore, in the drawings referred to below, reference numerals described in the following description may be omitted. Reference numerals omitted in the drawings referred to in the following description will be understood with reference to the referenced drawings for the above description.

10 to 12 is an operation diagram showing the operation of folding the packaging material by the folding device of the packaging material according to this embodiment.

10 to 12, the package 10 is transferred to the folding device 100 of the package in the y-axis direction by the package transporter 20 with the package 40 attached to the outer circumferential surface thereof.

Then, the position of the hub 200 relative to the package 10 is aligned. Alignment with respect to the y-axis of the hub 200 may be made by adjusting the position of the package support 20 by the package transporter 20. Alignment with respect to the x-axis of the hub 200 may be made by adjusting the position of the transfer structure 330 by the spacing adjuster 400. Alignment with respect to the z-axis of the hub 200 may be made by adjusting the position of the lifting body 310 by the lifting unit 300. At this time, the hub 200 may be aligned such that its central axis is located below the central axis of the package 10.

Subsequently, a preparation operation for folding the side end of the packaging material 40 is performed. That is, in the state where the plurality of first tanks 615 and the plurality of second tanks 622 are spaced apart from the packaging material 40 in the x-axis direction, the plurality of first tanks 615 are side surfaces of the packaging material 40. Located inside the end portion, the plurality of support arms 510 are transported so that the plurality of second tanks 622 are located outside the side end portions of the packaging material 40.

The hub 200 is then advanced toward the package 10. Accordingly, the side end portion of the packaging material 40 is positioned between the plurality of first tanks 615 and the plurality of second tanks 622.

Each first grip cylinder 611 then advances each rack rail 612. As each rack rail 612 is advanced, each pinion 613 is rotated about each first grip pin 613a. As each pinion 613 is rotated, each rotary arm 614 is rotated together. As each rotary arm 614 is rotated, each first tank 615 is rotated toward the plurality of second tanks 622. In addition, as the rotary arm 614 is rotated, the pressure cylinder 710 is extended, the plurality of pressure plate 720 is rotated based on the first link pin 731 is rotated toward the side of the package (10).

In addition, each second grip cylinder 621 presses each second tank 622. Each guide hole 623a guides each guide roller 622b so that each second tank 622 is rotated about each second grip pin 622a. Accordingly, each second 622 is rotated toward each first 615. Thus, each 1st tank 615 and each 2nd tank 622 are rotated toward each other, and hold the side edge part of the packaging material 40 in multiple places.

Subsequently, the plurality of support arms 510 are transferred inwardly of the hub 200, and the gap adjusting unit 400 transfers the hub 200 toward the package 10. Accordingly, the packaging material 40 is folded at the outer diameter edge portion of the package 10, the side end portion of the package 10 is transferred toward the inner diameter of the package 10.

As the grip part 600 holds the side end portion of the packaging material 40, and the side end portion of the packaging material 40 is transferred to the inner diameter portion of the package 10, a folding line is formed in the packaging material 40. The pressure plate 720 presses the packaging material 40 toward the side of the package 10.

13 and 14 is an operation diagram showing a state in which the pressing of the packaging material by the pressing unit in the folding device of the packaging material according to this embodiment.

13 and 14, the plurality of pressure plates 720 press the packing material 40 between the plurality of grip portions formed by the grip portion 600. At this time, as described above, the shock absorber 750 maintains a plurality of pressing plates 720 inclined at a predetermined angle with respect to the side surface of the packaging material 40.

Subsequently, the grip part 600 places a side end of the packaging material 40. That is, the plurality of first grip units 610 maintain the positions of the plurality of first tanks 615, and the plurality of second grip units 620 rotate the plurality of second tanks 622 to form the packing material 40. The side end portion of) may be separated from the plurality of first articles 615 and the plurality of second articles 622.

15 and 16, as the pressure is supplied to the rotating cylinder 830, the cylinder rod is extended. As the cylinder rod is extended, one side of the rotation cylinder 830 is constrained to the support ring 810 by the support shaft 831, and the other side of the rotation cylinder 830 rotates the variable shaft 832. As the variable shaft 832 is rotated, the rotary ring 820 is rotated along the outer circumferential surface of the hub 200 based on the center of the hub 200. As the rotary ring 820 is rotated, the plurality of support arms 510 are rotated, and the plurality of pressure plates 720 press the fold lines 41 and the packing material 40 is in close contact with the package 10. At this time, the rotational force is applied to each pressing plate 720 by the rotating part 800. Accordingly, each pressing plate 720 is rotated based on the hinge shaft 741, the shock absorber 750 is extended so that each pressing plate 720 can press the packaging material 40 on the entire surface.

In addition, the transfer unit 520 may transfer the plurality of support arms 510 in the outer diameter direction of the package 10 to press the packaging material against the side surface of the package 10 while the plurality of pressure plates 720 are rotated. Make sure As described above, the plurality of pressing plates 500 press the entire surface side of the package 10 to finish the folding process of the packaging material 40.

Subsequently, the packaging material 40 maintains a state in which the packaging material 40 is in close contact with the side surface of the package 10 by the plurality of pressure plates 500, and an operator or a separate taping device (not shown) is introduced to the inner diameter portion of the package 10. The tape can be glued.

On the other hand, in the present embodiment, the folding device 100 of the packaging material is shown as a pair is arranged on both sides with respect to the package 10, respectively. The folding device 100 of a pair of packaging materials may improve the process efficiency by performing a folding process of the packaging materials on both sides of the package 10. Of course, the folding device 100 of the packaging material is provided as one and disposed on one side of the package 10, the packaging 10 to be rotated 180 degrees to be modified to perform the folding process of the packaging material on both sides of the package 10 Can be.
