A bag making and packaging machine provided with a strip attachment device according to an embodiment of the band attachment device of the present invention will be described below with reference to FIGS.
[Overview]
A side view and a front view of the bag making and packaging machine 1 of the present embodiment are shown in FIGS. 1 and 2.
The bag making and packaging machine 1 is a machine that manufactures a bag by covering a product such as potato chips (here, potato chips) with a film and sealing the cylindrical film vertically and horizontally. The bag making and packaging machine 1 has a function of attaching the manufactured bag to a strip (band).

In principle, the potato chips are dropped from the weighing machine 2 provided above the bag making and packaging machine 1 by a predetermined amount.
The bag making and packaging machine 1 includes a bag making unit 10, a film roll holding unit 22, a strip mounting device (band body mounting device) 200 including a strip mounting unit 30 and a strip transport unit 41, a strip roll holding unit 42, It is comprised from the conveyance conveyor (conveyance mechanism) 85 and the control part 90 (refer FIG. 12). Each part except the conveyor 85 is fixed or supported by the frame 6 supported by the four legs 5, and most of the parts are covered with the casing 7 for safety.

[Film roll holder 22]
The film roll holding unit 22 holds a film roll 22a that feeds the sheet-like film F to the former 13a of the bag making unit 10 to be described later. The film roll 22a is obtained by winding a film F. The film F fed out from the film roll 22a is kept in a predetermined range by a dancer roller or the like, and loosening and meandering during conveyance are suppressed.

Further, a film remaining amount detection sensor 23 (see FIG. 12) for detecting the remaining amount of the film F wound around the film roll 22a is disposed in the vicinity of the film roll holding unit 22.
[Bag making part 10]
As shown in FIG. 3, the bag-making unit 10 includes a forming mechanism 13 that forms a film F that is fed in a sheet shape into a tubular shape, and a tubular film F (hereinafter referred to as a tubular film). A pull-down belt mechanism 14 that conveys downward, a vertical seal mechanism 15 that vertically seals the overlapping portion of the tubular film, and a horizontal seal that seals the upper and lower ends of the bag B by horizontally sealing the tubular film. And a mechanism 17.

<Molding mechanism 13>
The forming mechanism 13 includes a tube 13b and a former 13a. The tube 13b is a cylindrical member, and the upper and lower ends are open. Potato chips C weighed by the weighing machine 2 are put into the opening at the upper end of the tube 13b. The former 13a is disposed so as to surround the tube 13b. The shape of the former 13a is such that the sheet-like film F fed from the film roll 22a is formed into a cylindrical shape when passing between the former 13a and the tube 13b. Further, the tube 13b and the former 13a of the forming mechanism 13 can be replaced according to the size of the bag to be manufactured.

<Pull-down belt mechanism 14>
The pull-down belt mechanism 14 is a mechanism for adsorbing and transporting the tubular film wound around the tube 13b downward. As shown in FIG. 3, belts 14c are provided on both the left and right sides of the tube 13b. In the pull-down belt mechanism 14, the belt 14c having an adsorption function is rotated by the driving roller 14a and the driven roller 14b to carry the cylindrical film downward. In FIG. 3, a roller drive motor that rotates the drive roller 14a and the like is not shown.

<Vertical seal mechanism 15>
The vertical sealing mechanism 15 is a mechanism that heats and vertically seals the overlapping portion of the cylindrical film wound around the tube 13b against the tube 13b with a constant pressure. The vertical sealing mechanism 15 is located on the front side of the tube 13b, and has a heater and a heater belt that is heated by the heater and contacts an overlapping portion of the tubular film.

<Horizontal seal mechanism 17>
The horizontal sealing mechanism 17 is disposed below the forming mechanism 13, the pull-down belt mechanism 14, and the vertical sealing mechanism 15. The horizontal sealing mechanism 17 has a pair of sealing jaws 51 with a built-in heater (see FIG. 4). The pair of sealing jaws 51 are positioned on the front side and the rear side of the tubular film, respectively, and as shown in FIG. In the middle of turning, the tubular film is sandwiched in a state where the pair of sealing jaws 51 are pressed against each other, and pressure and heat are applied to the portions of the tubular film that are the upper and lower ends of the bag to seal. The sealing jaw 51 located on the front side of the tubular film is supported by the shaft 17c so as to rotate about the shaft 17c. The shaft 17c rotates through a gear 17d (see FIG. 18) by the operation of the turning motor 17a (see FIG. 12), and through a ball screw mechanism (not shown) by the operation of the shaft moving motor 17b. Move horizontally back and forth. Similarly, the sealing jaw 51 located on the rear side of the tubular film also rotates via the gear 17e (see FIG. 18) by the operation of the turning motor 17a and is moved back and forth by the operation of the shaft moving motor 17b. Move horizontally. Thus, the locus T of the substantially D-shaped sealing jaw 51 is realized by the pair of sealing jaws 51 rotating and moving horizontally. Further, the pressure when the pair of sealing jaws 51 sandwich the cylindrical film is adjusted by torque control of the shaft moving motor 17b.

A cutter (not shown) is built in one of the pair of sealing jaws 51. This cutter is different from the cutter 45 described later, and plays the role of separating the bag B and the subsequent cylindrical film at the center position in the height direction of the lateral seal portion by the sealing jaw 51.
13 and 14 show a lateral sealing operation by the pair of sealing jaws 51. FIG. In the example of the horizontal sealing operation shown in FIG. 13, the sealing jaw 51 that has swung sandwiches the cylindrical film at the point P10 (see FIGS. 13 (a) and 13 (b)), and moves downward as it is in the cylindrical shape. Pressure and heat are applied to the film, and the tubular film is released from the point P11 and separated from each other (see FIGS. 13C and 13D). In other words, the seal jaw 51 applies pressure and heat to the tubular film while moving downward at the same speed as that of the tubular film from the point P10 to the point P11, and performs horizontal sealing. And it cut | disconnects with a cutter and the bag B is discharged | emitted below by cancelling | pinching the cylindrical film which became the bag B in the point P11 (refer FIG. 10).

  FIG. 14 shows another example of the horizontal sealing operation. Here, the sealing jaw 51 turns while drawing a substantially D-shaped trajectory T2 different from the trajectory T. The sealing jaw 51 that has swiveled sandwiches the tubular film at a point P12 that is lower than the above-described point P10 (see FIGS. 14A and 14B), and moves downward as it is in the tubular shape. Pressure and heat are applied to the film, and the pinching of the tubular film is released at a point P11 to move away from each other (see FIGS. 14C and 14D). That is, the seal jaw 51 applies a pressure and heat to the tubular film while performing a horizontal seal while moving downward at the same speed as the tubular film from the point P12 to the point P11. And it cut | disconnects with the cutter incorporated in the sealing jaw 51, and the bag B is discharged | emitted below by canceling | releasing the clamping of the cylindrical film which became the bag B in the point P11.

  In the bag making and packaging machine 1, the sealing time is changed according to the size of the bag B to be manufactured, the material of the film F to be used, and the like. This change in the sealing time is mainly a change in the time during which the pair of sealing jaws 51 sandwich the upper and lower end portions of the bag B, and the cylindrical film in which the pair of sealing jaws 51 becomes the bag B is used. This can be done by shifting the point at which nipping starts and the point at which nipping of the tubular film is released. Here, as shown in FIGS. 13 and 14, the sealing time is changed by shifting the height position of the point at which the pair of sealing jaws 51 starts to sandwich the tubular film that becomes the bag B. Control is performed to keep the height position (release position) of the point at which the sealing film 51 that releases the cylindrical film from which the sealing jaw 51 becomes the bag B is released constant. That is, the point at which the pair of seal jaws 51 is released from the sandwiching of the tubular film that forms the bag B is that the pair of seal jaws 51 is positioned downward while the tubular film is sandwiched as shown in FIGS. Regardless of the distance traveled, the point P11 is fixed.

[Strip mounting device 200]
As shown in FIG. 21, a strip attachment device (band attachment device) 200 of this embodiment includes a strip attachment portion 30, a strip conveyance portion 41, conveyance guides (guide members) 48 and 49, and a conveyance conveyor (conveyance). Mechanism) 85 and a sensor (detection unit) 58. The strip attachment device 200 continuously attaches the plurality of bags B to the strip S conveyed from the strip conveyance unit 41 in the strip attachment unit 30. The bag B attached to the strip S is transported along the transport path formed by the transport guides 48 and 49 to the transport conveyor 85 disposed on the downstream side in the transport direction.

[Strip mounting part 30]
The strip attachment portion 30 performs an attachment operation in which the seal jaw 51 of the lateral seal mechanism 17 grips the bag B at a position where the manufactured bag B is released, and moves the bag B obliquely downward and welds it to the strip S. . The strip attachment part 30 includes a holding mechanism 31, a moving mechanism 32, and a fixing mechanism 33.

<Holding mechanism 31>
The holding mechanism 31 has a holding point P1 (see FIG. 10) on the basis of a fixing point P11 at which the sealing jaw 51 of the lateral sealing mechanism 17 releases the holding of the bag B, and the upper side of the left and right sides of the bag B. Each is gripped and held by a gripping arm 31b (see FIG. 6) that wraps around from both the front and rear sides. The holding point P1 is determined at a position lower than the fixed point P11 by a predetermined distance, and is always constant like the fixed point P11. That is, the holding point P1 is always at the same position even if the size of the bag B or the material of the film F is changed.

  As shown in FIG. 6, the holding mechanism 31 is a pair of left and right symmetrical mechanisms, and is incorporated in a main body 31a, two gripping arms 31b arranged on the upper side of the main body 31a, and the main body 31a. A holding air cylinder (not shown) and a fixing portion 31c fixed to a moving mechanism 32 described later are provided. The grip arm 31b is supported by the main body 31a so as to rotate about a vertical rotation axis arranged in parallel in the front-rear direction. The holding air cylinder built in the main body 31a is supplied with high-pressure air from a high-pressure air supply unit (not shown) through an on-off valve. When the holding air cylinder is actuated, the two gripping arms 31b rotate in the direction of the arrow indicated by the dotted line in FIG. The pair of holding mechanisms 31 arranged separately on the left and right sides are controlled at the same timing, and both the left and right sides of the bag B are simultaneously held by the four holding arms 31b.

<Movement mechanism 32>
The moving mechanism 32 will be described with reference to FIGS. 4 and 5. In FIG. 5, the gear box cover 201, the transfer rod cover 202, and the strip attachment portion cover 203 shown in FIG. 2 are omitted for easy understanding.
The moving mechanism 32 moves the holding mechanism 31 so that the bag B moves from the holding point P1 to a fixing point P2 (see FIGS. 4 and 10) described later. That is, the moving mechanism 32 moves the bag B from the holding point P1 to the fixing point P2 by moving the holding mechanism 31 that holds the bag B. Accordingly, the moving mechanism 32 allows the bag B (see the upper bag B in FIG. 4) attached to the strip S to be discharged from the lateral seal mechanism 17 downward (the upper portion in FIG. 10). The bag B is moved to a position where it does not interfere with the bag B).

  When the bag B discharged downward from the lateral seal mechanism 17 interferes with the bag B attached to the strip S, the lateral seal operation in the bag making section 10 (lateral seal mechanism 17) becomes unstable. Here, the holding point P1 and the fixing point P2 are shifted in the front-rear direction so that such interference can be avoided. Specifically, the holding point P1 and the fixing point P2 are shifted in the front-rear direction by a predetermined distance in consideration of the maximum thickness of the bag to be handled (the size of the bag in the front-rear direction), the posture of the bag B at the time of attachment, and the like. ing.

The moving mechanism 32 mainly includes a rail 72 whose upper and lower ends are fixed by a fixing member 71, a slide member 73 movable along the rail 72, a support member 74 fixed to the slide member 73, and a link member. 75, a rotating member 76, and a driving force transmission unit 210.
As shown in FIG. 4, the fixing member 71 (not shown in FIG. 5) is fixed to a pair of left and right side wall plates 30 a (see FIG. 5) that is detachably attached to the frame 6. The lower part is fixed in place so as not to move.

The rail 72 is inclined from the upper front side to the lower lower side in a side view, and supports the slide member 73 via a linear bush.
As will be described later, the slide member 73 is mechanically interlocked with the movement of the seal jaw 51 of the lateral seal mechanism 17 and repeats the reciprocating movement obliquely along the rail 72 in a side view. The slide member 73 is a pair of left and right members, and connecting rods 79a and 79b are spanned between both members.

  A support member 74 is fixed to the slide member 73 via connecting rods 79a and 79b. The support member 74 is a pair of left and right members, and extends obliquely forward on the upper side. Each upper end portion fixes the fixing portion 31 c of the holding mechanism 31. Therefore, the slide member 73, the support member 74, and the holding mechanism 31 are similarly repeatedly moved obliquely (up and down and back and forth).

  One end of the link member 75 is pin-supported at the lower end 73 a of the slide member 73. The other end of the link member 75 is pin-supported by a rotating end portion 76b (see FIG. 7) of the rotating member 76. When the rotating member 76 rotates according to the rotation of a rotating shaft 76a (described later) fixed at the center of rotation, the link member 75 assumes the posture shown in FIG. 4 or the posture shown in FIG. The slide member 73 is pulled down or pulled up obliquely.

The driving force transmission unit 210 includes a rotating shaft 76a, pulleys 66a, 67, 68, 69, 70, belts 66b, 67a, 69a, and a transfer rod 68a. The driving force transmission unit 210 is detachably attached to the frame 6. ing.
The left and right rotating shafts 76a that rotate the pair of left and right rotating members 76 are rotated by the rotation of the pulleys 67 and 70, respectively. As shown in FIGS. 5 and 18, the pulley 67 is non-rotatably coaxially connected to the pulley 66a by a lock member 66d, and rotates in conjunction with the rotation of the pulley 66c via the belt 66b. As shown in FIGS. 5 and 18, the pulley 66c is fixed to a gear 17d that rotates the seal jaw 51 of the lateral seal mechanism 17, and drives the turning motor 17a (see FIG. 12) of the lateral seal mechanism 17. It will rotate by force. That is, the pulley 67 fixed to the right rotation shaft 76 a is rotated by the driving force of the turning motor 17 a of the lateral seal mechanism 17. Further, the pulley 70 fixed to the left rotating shaft 76a also rotates in conjunction with the pulley 67 via the pulleys 68 and 69, the belts 67a and 69a, and the transfer rod 68a (see FIGS. 5 and 20). The pulley 68 and the transfer rod 68a are non-rotatably connected via a lock member 68b. As shown in FIG. 19, the rotary shaft 76a is rotatably supported by shaft support members 76c and 76d.
