And cut between the end seals. Therefore, the continuous bag which made the header continue to the conveyance direction final end side of a product bag can be manufactured with the same packaging material (refer the paragraph 2 to the paragraph 3 of patent document 2).

  Conventionally, the box packing of this type of continuous bag with a header has not been automated, and has been boxed after being manually folded. For example, as shown in FIG. 8, the header 1, the first bag 2, the second bag 3, the third bag 4, and the fourth bag 5 each have a perforation 11 in the middle portion of the horizontal seal 10. In the case of a continuous four-bag bag with a header, the folding method is as shown in FIG. 9, after folding the header 1 of the continuous bag with header, which has been conveyed with the back surface 14 of the bag up, In the middle part of the second bag 3 and the third bag 4 which are the middle part of the continuous package, it was folded upward and folded to about half the length and put in the box with the surface 13 facing up. In addition, a hook-mounted mount 61 for store display may be placed in the box at the end of packing. As shown in FIG. 11, the display 61 with hook for store display is displayed by attaching an S-shaped hook 64 to a mount 63 with a hanging strap 62 and hanging the header-attached continuous packaging bag 61 on the S-shaped hook 64. It is a member.

It is desired to automate the process of folding the header-attached continuous bag into a half length and packing the bag with the bag facing up. However, it is impossible to follow the method that has been performed manually and to automate it. As shown in FIG. 10, when the continuous bag folded by the conventional method is sucked and moved, the first bag 2 and the second bag 3 above the folded continuous bag are sucked by the suction pads 16 and 16. This is because the folded header-attached continuous bag is broken when lifted for transport.

Thereby, the position of the folding claws 21a and 21b can be adjusted in a direction approaching each other or in a direction away from each other. This is to make it possible to use both a four-pack with a header and a bag having a different length. The adjustment shaft 56 is fixed to the middle frame base 35 by a support member 58. Further, rotary actuators 25a and 25b are connected to the end portions of the rotating shafts 24a and 24b. The rotary actuators 25a and 25b are drive sources for rotating the rotation shafts 24a and 24b, and in this embodiment, air pressure type rotary actuators are used. When the rotary actuators 25a and 25b operate, the rotation shafts 24a and 24b rotate, and the return claws 21a and 21b rotate upward.

  Operation | movement of the folding apparatus 40 of the continuous packaging bag with a header is demonstrated using FIG. The four-pack bag with a header carried into the apparatus with the back surface 14 of the bag facing up by the inclined conveyor 41 (omitted in FIG. 4, see FIG. 2) is received by the bag transport belts 22a and 22b. When the quadruple sachet with a header has passed under the sensor 31, it stops (see FIG. 3 for the sensor 31). Simultaneously with the stop of the bag transport belts 22a and 22b, a blower (not shown) is operated to suck and fix the second bag 3 and the third bag 4 to the bag suction hole 34 of the vacuum box 20 (the suction hole 34 is shown in the figure). 3). Next, the rotary actuator 25a is operated to turn the folding claw 21a upward, and the header 1 and the first bag are folded upward between the first bag 2 and the second bag 3 (about the rotary actuator 25a). (See FIG. 3). Thereby, the header 1 and the first bag 2 are folded on the second bag 3 and the third bag 4 with the bag surface 13 facing up. Next, the operation of the rotary actuator 25a is released, the return claw 21a is returned to its original position, and the rotary actuator 25b is operated to turn the return claw 21b upward, so that the fourth bag 5 and the third bag 4 It folds upward between the second bag 5 (see FIG. 3 for the rotary actuator 25b). As a result, the fourth bag 5 is folded onto the third bag 4 with the bag surface 13 facing up. Next, the operation of the rotary actuator 25b is released, the folding claw 21b is returned to the original position, and the blower is released. Thereby, the folded continuous bag 60 with a header is completed. Further, the blower may release the operation from the completion of the folded header-attached continuous packaging bag 60 to the suction conveyance by the suction pad 16, and may operate at all other times.

The number of padding and the pattern of padding can be arbitrarily set. For example, even if there are 10 patterns with the same 3-stage product, it is possible to place two of the second-stage postures side by side horizontally rotated 45 degrees from the posture at the time of suction. It is also possible to stack four by three in a state where it is rotated 90 degrees horizontally from the posture of the time to make 12 pieces. When the boxing process is completed, the cardboard box 45 is carried out of the apparatus by the box conveying device 42.

  By the way, there may be cases where the same bag size has a different number of continuous packages. However, the problem with this case is that a combination of different numbers of continuous packages to be described becomes a problem. That is, the stop position of the wrapping bag, the folding position of the sack, and the suction fixing position of the sack are greatly changed. Therefore, if these are configured to be position-adjustable, it is possible to cope with them. An example will be described with reference to FIGS. FIG. 6 is a diagram for explaining a folding device 40 for a header-attached continuous bag having a different number of continuous packages, and FIG. 7 is a diagram for explaining a folding method and a suction pad 16 in the case of using a different number of continuous packages. is there.

  The folding device 40 for the header-attached continuous bag shown in FIG. 6 has the same basic configuration as that of the 4-header-attached bag folding device with the header shown in FIG. The main part is configured to be positionally adjustable. That is, the folding claw 21a for folding the bag connected to the header and the suction fixing vacuum box 20a for the folding are arranged on the slide base 50a, and the bag at the end of the continuous package opposite to the header is folded. The return claw 20b and the suction fixing vacuum box 20b are arranged on the slide base 50b so that the position can be adjusted. The slide bases 50a and 50b are both slidably assembled on the slide rails 51a and 51b. The slide rails 51a and 51b are fixed to the middle frame base 35 of the machine frame. Thereby, it is possible to largely adjust the folding position. The slide bases 50a and 50b are provided with a clamp member 52 for fixing the position, and the position can be fixed by making the clamp member 52 effective.

  FIG. 7 shows how to fold from 3 to 8 packages and the suction position. The present invention folds the header-attached continuous bag into half lengths, and is an odd number of continuous packages that cannot be divided. In the case of, it is rounded up. The following describes how to fold three to eight packages. In the case of a triple-packed bag with a header, the third bag 4 is fixed by suction, and only the header 1 and the first bag 2 are folded back. In the case of a quadruple-pack with a header, it is omitted because it has been described above. In the case of a five-pack bag with a header, the second bag 3 to the fourth bag 5 or the second bag 3 and the fourth bag 5 are adsorbed and fixed, and the header 1 and the first bag 2 and the fifth bag 5 are fixed. Fold the th bag 6 back.
