The bag detection sensor 31 detects the quadruple packaging bag with a header that has been brought in, and the control device (not shown) that receives the detection signal determines when the quadruple packaging bag with a header has passed under the sensor 31. Or, it is determined that the quadruple bag with a header has reached a predetermined position after a certain period of time after passing through.

The vacuum box 20 is installed in the middle of the two bag transport belts 22a and 22b in the longitudinal direction so as to penetrate the inside of the wound belt, and the bag suction holes 34 are provided in the two bag transport belts 22a, It is exposed from between 22b. The vacuum box 20 is fixed to the machine frame middle stage base 35 via the vacuum box mounting member 32 on the lower side of both ends thereof. The vacuum box 20 is connected to a blower (not shown) via a pipe, and when the blower operates, air is sucked from the bag suction hole 34. When the blower is operated when the quadruple packaging bag with a header is transported to the above-mentioned predetermined positions by the two bag transport belts 22a and 22b and stopped, the four bag with a header located above the bag suction hole 34. The second bag 3 and the third bag 4 of the continuous bag are sucked into the bag suction hole 34 and fixedly held.

The folding claws 21a and 21b are arranged in the vicinity of the vacuum box 20 of the two bag conveying belts 22a and 22b, and are members for guiding the bag conveyed above the vacuum box 20 and folding it upward. The folding claws 21a and 21b are formed into a unique shape by being curved and are fixed to the rotating shafts 24a and 24b. Therefore, when the rotating shafts 24a and 24b rotate, the rotating shafts 24a and 24b Turn with. That is, the folding claws 21a and 21b can be rotated in the front-rear direction of the fixing means by rotating the rotating shafts 24a and 24b. The rotating shafts 24a and 24b are movably fixed to the adjusting shaft 56 and the support shaft 59 via the brackets 26a, 26b, 26c and 26d. The support shaft 59 penetrates the brackets 26a and 26b, and the brackets 26a and 26b are slidable on the support shaft 59. The support shaft 59 is fixed to the machine frame middle stage base 35 by the support members 58 and 58. A screw portion 57a is provided near the contact portion of the adjusting shaft 56 with the bracket 26c, and a screw that meshes with the bracket 26c is also provided. Further, a screw portion 57b is provided near the contact portion of the adjusting shaft 56 with the bracket 26d, and the bracket 26d is also provided with a screw that meshes with the bracket 26d. The screw portion 57a and the screw portion 57b are screwed in opposite directions. When the adjusting handle 55 is operated to rotate the adjusting shaft 56, the brackets 26c and 26d are screwed on the adjusting shaft 56 in the direction of approaching or separating from each other by the screwing action. As a result, the positions of the folded claws 21a and 21b can be adjusted in the direction of approaching each other or in the direction of separating from each other. This is so that both a quadruple package with a header and a bag with different bag lengths can be used together. The adjusting shaft 56 is fixed to the machine frame middle stage base 35 via a support member 58. Further, rotary actuators 25a and 25b are connected to one end of the rotating shafts 24a and 24b. The rotary actuators 25a and 25b are drive sources for rotating the rotating shafts 24a and 24b. In this embodiment, a pneumatic rotary actuator is used. When the rotary actuators 25a and 25b operate, the rotating shafts 24a and 24b rotate, and the folding claws 21a and 21b rotate upward.

As shown in FIG. 3, the folding claws 21a and 21b, which are folding means, are members formed into a unique shape according to the present invention. As shown in the enlarged view of FIG. 3C, the folding claws 21a and 21b are in an inverted state (solid line) before folding and an upright state (imaginary line) after folding due to the rotation of the rotating shafts 24a and 24b. ) Is rotatable. The folding claws 21a and 21b are bent and rotated substantially at right angles to the bases 70a and 70b fixed to the rotating shafts 24a and 24b and from the tips of the bases 70a and 70b in the same direction as the rotation direction when folding back. The claw body portions 71a and 71b extending in an offset state with respect to the shafts 24a and 24b and the claw body portions 71a and 71b are further bent at a substantially right angle in the same rotational direction from the tips of the claw body portions 71a and 71b in a posture substantially parallel to the base portions 70a and 70b. The bag-raising portions 72a and 72b, the bag-raising portions 73a and 73b extending from the tips of the bag-holding portions 72a and 72b in a direction opposite to the turning direction, and the bag-raising portions 73a and 73b. It is provided with tip portions 74a and 74b which are bent at a substantially right angle in a direction opposite to the turning direction from the tip and slightly extend.

The folded claws 21a and 21b are provided with base portions 70a and 70b, claw body portions 71a and 71b, bag holding portions 72a and 72b, bag raising portions 73a and 73b, and tip portions 74a and 74b to provide the folded claws 21a and 21b. It has a compact structure, and can effectively hold the bag by turning it in a small turn even during operation. The bag raising portions 73a and 73b extend in a direction away from the bag holding portions 72a and 72b, and are positioned so as to face the outside of the bottom surface (surface 13) of the bag to be folded back in the folded state of the folding claws 21a and 21b. (See Fig. 4 (1) for details). The bag raising portions 73a and 73b efficiently perform a bag raising action for folding back the bag by abutting against the bottom surface of the bag as the folding claws 21a and 21b stand up. In the upright state in which the folded claws 21a and 21b are swiveled, the curved claw main bodies 71a and 71b can wrap around the outside of the folded edges 17 and 18 of the bags 3 and 4 in the fixed state without being folded, and are folded. Rentsutsumibukuro 101 can Rukoto occupy the position for regulating the position of the folded edge 17, 18 so as not to protrude outside in the longitudinal direction of the continuous packaging bag pressing portions 72a, 72b are folded folding Rentsutsumibukuro 101 The bag raising portions 73a and 73b are brought into contact with the upper surface of the bag and pressed, and the bag raising portions 73a and 73b take a posture of extending upward from the bag surface 13 and away from the bag (details are shown in FIGS. 4 (2) and (3)). See). The folded claws 21a and 21b are preferably formed of rod-shaped members having a smooth surface, and each bent portion having a substantially right angle is also bent with a gentle curvature. Further, since the bag holding portions 72a and 72b are not the ends of the rod-shaped members as they are, but are bent and connected to the bag raising portions 73a and 73b to the tip portions 74a and 74b, a sharp tip is formed. Does not hit the bag. The smooth bent portions of the folded claws 21a and 21b do not damage the bag, and in particular, the bag raising portions 73a and 73b and the tip portions 74a and 74b do not hit the bag with edges in the upright state. As described above, the shape and structure of the folded-back claws 21a and 21b have been devised so as not to damage the bag as a whole.

The operation of the folding device 40 will be described with reference to FIG. The quadruple packaging bag with a header is carried into the apparatus by an inclined conveyor 41 (omitted in FIG. 4, see FIG. 2) with the back surface 14 of the bag facing up.
(1) The quadruple packaging bag with a header that has been carried in is delivered to the bag transport belts 22a and 22b, and stops when the quadruple packaging bag with a header has passed under the sensor 31 (the sensor 31 is shown in FIG. See 3). At the same time that the bag transport belts 22a and 22b are stopped, 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 FIG. See 3). It is preferable that the quadruple packaging bag with a header, which is suction-fixed to the vacuum box 20, is lifted by abutting the front and rear end sides of the folding claws 21a and 21b as much as possible and using a flat plate-shaped portion. As a portion that meets these conditions, the bag raising portions 73a and 73b are brought into contact with the front and rear ends (ends far from the rotating shafts 24a and 24b) of the bag, and the folding claws 21a and 21b rotate in that state to cause the header. 1 and the first bag 2 and the fourth bag 5 are lifted.

(2) Next, the rotary actuator 25a is operated to rotate 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 (rotary). See FIG. 3 for the actuator 25a). As a result, the header 1 and the first bag 2 are folded on the second bag 3 and the third bag 4 with the surface 13 of the bag facing up. Further, by operating the rotary actuator 25b, the folding claw 21b is swiveled upward, and the fourth bag 5 is folded upward between the third bag 4 and the fourth bag 5 (for the rotary actuator 25b). See FIG. 3). As a result, the fourth bag 5 is folded onto the third bag 4 with the surface 13 of the bag facing up. The folding operation of the folding claw 21b may be performed at the same time as the folding operation of the folding claw 21a, but it is preferable to perform the folding operation of the folding claw 21a in order with a time delay.

(3) The suction pads 16 and 16 start the lowering operation while the folded claws 21a and 21b are still swiveled. When the folding claws 21a and 21b are swiveled and the bag holding portions 72a and 72b are in a state of pressing the folding continuous packaging bag 101 from above, the suction pads 16 and 16 are lowered to suck the folding continuous packaging bag 101. Operate. That is, the suction pads 16 and 16 waiting above are lowered with respect to the folded continuous packaging bag 101 which is in the folded state by the folding claws 21a and 21b turning and folding the bags at both ends upward. The first bag 2 and the fourth bag 5 located on the upper side of the folding continuous packaging bag 101 are adsorbed. Therefore, the folded state of the folding continuous packaging bag 101 is not broken, and the folding continuous packaging bag 101 is surely sucked by the suction pads 16 and 16. The suction pads 16 and 16 interfere with the folding claws 21a and 21b so that the folding continuous packaging bag 101 can be sucked by the suction pads 16 and 16 while the bag holding portions 72a and 72b hold the folding continuous packaging bag 101. It has a structure and arrangement that does not. That is, the swirled folded-back claws 21a and 21b have a form in which the bag raising portions 73a and 73b extend in a direction away from the surface 13 of the bag, and the suction pads 16 and 16 are within the width between the bag raising portions 73a and 73b. Since the suction pads 16 and 16 have a size and structure that can be lowered, the suction pads 16 and 16 can be lowered without interfering with any of the swirled turn-back claws 21a and 21b.

(4) Opening of the folding claws 21a and 21b Next, the operation of the rotary actuator 25a is released, the folding claw 21a is returned to the original position, the operation of the rotary actuator 25b is released, and the folding claw 21b is returned to the original position. Release the operation of the return blower. As a result, the folding continuous packaging bag 101 is completed. The opening (return) operation of the folding claw 21b may be performed at the same time as the opening (return) operation of the folding claw 21a, but it is preferably performed in order with a time delay. Further, the blower may release the operation from the completion of the folding continuous packaging bag 101 to the suction transfer by the suction pads 16 and 16, and may always operate at other times.

(5) The suction pad 16 sucks the first bag 2 and the fourth bag 5 located on the upper side, and is transported to the cardboard box. A predetermined number of folding continuous packaging bags 101 are sequentially conveyed to the cardboard box 60.

FIG. 8 is a diagram showing an example of a control device and a flowchart followed when the control device controls a folding operation. The control device 60 is arranged in relation to the folding device (see FIG. 2) 40, and as shown in FIG. 8A, sensor signals from the bag detection sensor 31 and various sensors, and a setting unit. For the rotary actuators 25a and 25b and the suction transfer device 47 (particularly, the suction part 48 is raised and lowered) based on the setting signals regarding the bag size such as the number of consecutive packages and the bag length in the above. Outputs a signal that controls the operation of the servo motor and air cylinder. The turning operation of the folding claws 21a and 21b and the raising and lowering operation of the suction pads 16 and 16 are performed based on the flowchart shown in FIG. 8 (b). That is, the continuous packaging bag 100 with a header is folded back by the turning operation of the folding claws 21a and 21b (step 1; abbreviated as "S1"; the same applies hereinafter). The turning operation of the folding claws 21a and 21b is completed (S2). After that, the lowering operation of the suction pads 16 and 16 is started (S3). The suction pads 16 and 16 suck the bags with the upper surface facing up in a state where the bags at both ends are folded back by the folding claws 21a and 21b and the folded state is maintained by the folding claws 21a and 21b (S4). After that, the folding claws 21a and 21b open (return) and start the operation (S5) while the bag suction by the suction pads 16 and 16 is held. That is, in a state where the folding continuous packaging bag 101 is surely sucked by the suction pads 16 and 16, the folding claws 21a and 21b are opened (returned) to return. The folding continuous packaging bag 101 held in the folded state by the folding claws 21a and 21b is conveyed to the box in a state of being sucked by the suction pads 16 and 16 (S6). By going through such a procedure, the bag of the folding continuous packaging bag 101 does not come apart.

In the case of this embodiment, the number of folding continuous packaging bags packed in the cardboard box 60 is 10 in a three-tiered product. As shown in FIG. 5, the first and third stages have a pattern in which four are arranged side by side in a state of being rotated 90 degrees horizontally from the posture at the time of suction, and the second stage is arranged in a pattern in which two are arranged side by side in the posture at the time of suction. be. The individual packing number and packing method pattern are configured to be arbitrarily set. For example, even if there are 10 patterns in the same 3-stage product, it is possible to place two of them side by side with the posture of the second stage rotated 45 degrees horizontally from the posture at the time of adsorption, and all of them are adsorbed. It is also possible to stack four or three layers in a state of being rotated 90 degrees horizontally from the posture at the time to pack 12 pieces. When the boxing process is completed, the cardboard box 45 is carried out of the device by the box transfer device 42.

By the way, even if the size of the bag is the same, there may be cases where different numbers of packages are used together. The stop position of the packaging bag, the folding position of the bag, and the suction and fixing position of the bag change significantly. Therefore, if these are configured so that their positions can be adjusted, it is possible to deal with them. An example thereof will be described with reference to FIGS. 6 and 7. FIG. 6 is a diagram for explaining a folding device 40 capable of using different numbers of continuous packages, and FIG. 7 is a diagram for explaining a folding method and a suction pad 16 when different numbers of continuous packages can be used together.

The folding device 40 shown in FIG. 6 has the same basic configuration as the folding device for the quadruple packaging bag with a header shown in FIG. It is configured to be adjustable in position. That is, in order to dispose the folding claw 21a for folding back the bag on the side connected to the header and the suction fixing vacuum box 20a for that purpose on the slide base 50a, and to fold back the bag at the end of the continuous packaging on the opposite side of the header. The folding claw 20b and the suction fixing vacuum box 20b for that purpose are arranged on the slide base 50b so that the position can be adjusted. Both the slide bases 50a and 50b are slidably assembled on the slide rails 51a and 51b. The slide rails 51a and 51b are fixed to the machine frame middle stage base 35. This makes it possible to greatly adjust the folding position. Further, the slide bases 50a and 50b are provided with a clamp member 52 for fixing the position, and the position can be fixed by enabling the clamp member 52.

FIG. 7 shows how to fold from triple to eight packages and the suction position. In the present invention, the header bag is folded in half, and the number of packages is an odd number that cannot be divided. In the case of, it is rounded up and processed. The following is a list of folding methods from triple packaging to eight packaging. In the case of a triple packaging bag with a header, the third bag 4 is adsorbed and fixed, and only the header 1 and the first bag 2 are folded back. In the case of a quadruple bag with a header, it is omitted because it is 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 5 are fixed. Fold back the second bag 6. In the case of a six-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 sucked and fixed, and the header 1 and the first bag 2 and the fifth are fixed. Bag 6 and the sixth bag 7 are folded back. In the case of a seven-pack bag with a header, the second bag 3 to the fifth bag 6, or the second bag 3 and the fourth bag 5 are sucked and fixed, and the header 1 and the first bag 2 and 6 are fixed. Fold back the 7th bag 7 and the 7th bag 8. In the case of an eight-bag with a header, the third bag 4 to the sixth bag 7, or the third bag 4 and the sixth bag 7 are sucked and fixed, and the header 1, the first bag 2 and 2 are fixed. Fold back the third bag 3, the seventh bag 8, and the eighth bag 9.

As described above, as the number of continuous packages increases, the folding interval increases. Therefore, the slide bases 50a and 50b are appropriately adjusted so that the interval increases, and when the number of continuous packages decreases, the slide tables 50a and 50b approach each other. It may be adjusted as appropriate.

Next, for the suction portion 48, a plurality of attachment ports for the suction pads 16 are prepared, the attachment ports for attaching the suction pads 16 are changed according to the number of consecutive packages, and the unused attachment ports are closed with the blocking plug 53. You can leave it at. Further, the suction portion 48 itself may be replaced.

Further, in the automatic boxing device for the continuous packaging bag with a header of the present invention, a device for loading a mount with a hook for displaying the continuous packaging bag with a header in a store can be installed in the space 54 above the box carry-out portion shown in FIG. It is possible.
