[First Embodiment]
First, the packaging bag to be processed in this embodiment will be described.

  FIG. 1 is a plan view showing an example of the packaging bag 100. The packaging bag 100 has a plurality of storage chambers, and in the example shown in FIG. 1, two storage chambers (that is, the first storage chamber 101 and the second storage chamber 102) are formed. A partition 104 is formed between the first storage chamber 101 and the second storage chamber 102 provided adjacent to each other in the packaging bag 100.

  The front surface (that is, the first side surface 111) and the back surface (that is, the second side surface 112) of the packaging bag 100 are integrally formed on both side portions 103, the partition portion 104, and the bottom portion 106 of the packaging bag 100. No space is formed in. On the other hand, the first storage chamber 101 and the second storage chamber 102 are spaces formed between the front surface and the back surface of the packaging bag 100, and are partitioned by the side portion 103, the partition portion 104, and the bottom portion 106.

  A bag mouth 105 is formed at the upper end of each of the first storage chamber 101 and the second storage chamber 102. The bag mouth 105 communicates the inside and the outside of the packaging bag 100, and the contents can be put into the first storage chamber 101 and the second storage chamber 102 via the bag mouth 105.

  Next, a bag filling and packaging machine that encloses the contents in the packaging bag 100 shown in FIG. 1 will be described.

  FIG. 2 is a plan view showing an example of the bag filling and packaging machine 10.

  The bag filling and packaging machine 10 includes a disk-shaped transport body 14 provided on a gantry 12, a conveyor magazine 16 disposed around the transport body 14, a first input section 17, a second input section 18, and a first sealing device. 19 and the second sealing device 20 and the like.

  The carrier 14 is provided so as to be rotatable around the central axis, and is intermittently rotated by being driven by a rotation driving device (not shown). The arrows shown in FIG. 2 indicate the direction of shaft rotation of the transport body 14.

  A plurality of support portions constituted by grippers or the like are fixedly provided on the outer peripheral portion of the transport body 14, and each support portion rotates together with the transport body 14. The bag filling and packaging machine 10 of the present embodiment employs a so-called double-type transport system, and the transport body 14 includes a plurality of support portions (two support portions in the present embodiment) at each of the plurality of stations A1 to A10. Move intermittently to stop sequentially. In each of the plurality of stations A1 to A10, two or more support parts (two support parts in the present embodiment) are stopped in one intermittent stop period. The transport body 14 with a plurality of support portions (two support portions in this embodiment) arranged so that a plurality of packaging bags 100 (two packaging bags 100 in this embodiment) can be processed in one station. Is provided. Thus, the multi-type (double-type in this embodiment) bagging and packaging machine 10 capable of processing a plurality of packaging bags 100 at a time at each station exhibits an excellent packaging capability.

  In the example shown in FIG. 2, the packaging bag 100 is supplied to the support portion at the station A1 (that is, the bag feeding station), and the packaging bag 100 is supported by the support portion. In other words, the station A1 is provided with a bag feeding device (see reference numeral 81 in FIG. 12 described later), and the packaging bags 100 stored in the conveyor magazine 16 are taken out one by one by the bag feeding device and are attached to the respective support portions. Passed.

  Note that the bag supply device passes the packaging bag 100 to the support unit in the state where the upper edge portion of the packaging bag 100 is gripped at the station A1. By grasping the upper edge of the packaging bag 100 in this manner, the bending of the packaging bag 100 hardly occurs and the packaging bag 100 can be stably supplied to the support portion. On the other hand, in the configuration in which the bag feeding device grips the upper edge of the packaging bag 100, the bag feeding device usually interferes with the support portion when the packaging bag 100 is delivered. According to the packaging machine 10, such interference can be avoided.

  In the station A2, a printing process is performed, and desired characters and the like are printed on the packaging bag 100. In the station A3, a printing inspection process is performed, and the suitability of the printing state of the packaging bag 100 is certified.

  In the station A4, an opening process is performed, and the bag opening 105 of the first storage chamber 101 and the second storage chamber 102 of the packaging bag 100 is opened. The opening of the bag mouth 105 can be performed by an arbitrary method. Typically, the pair of suction means are arranged so as to be separated from each other in a state where each of the bag surfaces (that is, the first side surface 111 and the second side surface 112) of the packaging bag 100 is held by a pair of suction means such as a suction cup. By moving, each bag mouth 105 of the first storage chamber 101 and the second storage chamber 102 can be opened. In the opening process of the bag mouth 105, both side portions 103 of the packaging bag 100 are moved in a direction approaching each other by the support portion.

  In the station A5, a solid material charging process is performed, and solid contents are charged into the first storage chamber 101 and the second storage chamber 102 from the first charging unit 17 through the bag mouth 105. The first charging unit 17 for charging the solid content can have, for example, a funnel (hopper). In the station A6, a liquid material charging process is performed, and liquid contents are charged into the first storage chamber 101 and the second storage chamber 102 from the second charging unit 18 through the bag mouth 105. The second charging unit 18 for charging the liquid content can have, for example, a liquid filling nozzle. As described above, each of the first input unit 17 and the second input unit 18 passes through the bag openings 105 of the first storage chamber 101 and the second storage chamber 102, and the first storage chamber 101 and the second storage chamber 102. Put contents into each.

  The number of input parts and the type of contents are not particularly limited. For example, only a single input unit may be provided, or three or more input units may be provided. Further, in addition to or instead of the solid content and the liquid content, the gaseous content, the gel content, or the mixture of the contents in a plurality of types is provided in the first storage chamber via the input unit. 101 and the second storage chamber 102 may be stored.

  In the station A7, no particular processing is performed, and the packaging bag 100 is conveyed to the subsequent station A8. In the station A8 (that is, the sealing station), the first sealing process is performed, and the bag openings 105 of the first storage chamber 101 and the second storage chamber 102 are thermocompression bonded by the first sealing device 19 and closed. In the station A9 (that is, the sealing station), the second sealing process is performed, and the second sealing device 20 performs further thermocompression bonding of the bag ports 105 of the first storage chamber 101 and the second storage chamber 102. Thus, the 1st sealing device 19 and the 2nd sealing device 20 which seal each bag mouth 105 of the 1st storage chamber 101 of the packaging bag 100 supported by a support part and the 2nd storage chamber 102 are bag supply devices. From the position where the packaging bag 100 is passed to the support part (ie, station A1) and the stations A2 to A7.

  The first sealing process and the second sealing process described above can be performed by any method. Typically, the 1st sealing device 19 and the 2nd sealing device 20 are comprised with a hot plate with respect to the scheduled sealing part of the packaging bag 100 in the state which strained the bag mouth 105 of the packaging bag 100. FIG. The bag mouth 105 can be sealed by pressing a seal portion (see reference numerals “143” and “144” in FIGS. 16 and 17 described later). The tension state of the bag mouth 105 can be realized by an arbitrary method. For example, in a state in which both side portions 103 of the packaging bag 100 are gripped by side support portions (see first side support portion 61 and second side support portion 62 in FIG. That is, such a tension state can be created by moving the side support portion in the width direction of the packaging bag 100.

  In the station A10, a cooling discharge process is performed, and the portion of the bag mouth 105 of the packaging bag 100 that has been thermocompression bonded is cooled. Further, at the station A10, the packaging bag 100 is released from the support portion, the packaging bag 100 is dropped on a conveyor (not shown), and the packaging bag 100 is sent to the subsequent apparatus by the conveyor. The packaging bag 100 whose support is released at the station A10 is a product bag in which the contents are put into the first storage chamber 101 and the second storage chamber 102 and the bag opening 105 is sealed. In the station A10, the mechanism for releasing the support of the packaging bag 100 by the support unit 60 can be realized by an arbitrary mechanism, for example, a mechanism having a combination of a cam and a cam follower.

  Note that FIG. 2 shows only a part of equipment necessary for processing performed in the stations A1 to A10. For example, at the station A1, the packaging bags 100 are taken out one by one from the conveyor magazine 16 by a bag feeding device (not shown) and delivered to a support provided on the transport body 14. The station A2 and the station A3 are provided with a printing device and a printing inspection device (not shown). The station A4 is provided with an opening device (not shown), and the station A10 is provided with a cooling device and a discharge device (not shown).

  In addition, the packaging bag 100 in which a defect has occurred (hereinafter also referred to as “defective bag”) is outside the bag packaging machine 10 at a location other than the location where the good packaging bag 100 is discharged (for example, any one of stations A4 to A9). Is discharged.

  Next, the support part provided in the conveyance body 14 is demonstrated.

  FIG. 3 is a block diagram illustrating functional configurations of the support unit 60 and the support driving device 66.

  Each of the plurality of support portions 60 fixedly provided on the transport body 14 includes a side support portion for supporting both side portions 103 of the packaging bag 100 (a “first side support portion 61 shown in FIG. And the “second side support portion 62”) and an intermediate support portion 63 for supporting the partition 104 of the packaging bag 100.

  On the other hand, the support drive device 66 is a device that drives the support portion 60 and switches between support and non-support of the packaging bag 100 by the support portion 60. The support drive device 66 includes a side support drive unit 67 that drives the side support units 61 and 62, and an intermediate support drive unit 68 that drives the intermediate support unit 63.

  The support unit 60 and the support drive device 66 can be configured by arbitrary devices. For example, typical examples of the intermediate support unit 63 and the intermediate support drive unit 68 will be described later with reference to FIGS. On the other hand, the side support parts 61 and 62 and the side support drive part 67 can be configured by known devices. For example, the side support parts 61 and 62 are configured by grippers capable of gripping the side part 103 of the packaging bag 100. In addition, the side support drive unit 67 can be configured by a mechanism capable of switching between gripping and non-gripping operations of the gripper. As an example, the side support portions 61 and 62 and the side support drive portion 67 can be configured by a bag gripping device as disclosed in JP-A-6-156440. That is, the side support portions 61 and 62 are constituted by a chuck having a fixed portion and a movable portion, and the movable portion is urged toward the fixed portion by an elastic member such as a spring and the movable portion via the link mechanism. The side support drive unit 67 can be configured by a device that can be separated from the fixing unit.

  For example, when the opening process is performed at the above-described station A4, the partition 104 of the packaging bag 100 is supported by the intermediate support portion 63 while the side portions 103 of the packaging bag 100 are supported by the side support portions 61 and 62. In the state, the side support parts 61 and 62 are moved to bring the both side parts 103 closer to each other. Thereby, each bag mouth 105 of the 1st storage chamber 101 and the 2nd storage chamber 102 is opened smoothly.

  Next, detailed configuration examples of the support unit 60 and the support drive device 66 will be described.

FIG. 6 is a plan view showing a configuration example of the side support portions (the first side support portion 61 and the second side support portion 62) and the intermediate support portion 63, and is mainly fixed to the transport body 14. The members are shown. FIG. 4 shows a pair of intermediate support portions 63 and intermediate support portions 63. In FIGS. 5 and 6, only the configuration in the vicinity of the station A10, the station A1, and the station A2 is shown in a simplified manner.

  A fixed shaft 22 constituting a center shaft is provided at the center of the disc-shaped transport body 14, and a rotating shaft 21 is provided so as to surround the periphery of the fixed shaft 22. The fixed shaft 22 is provided as a member that cannot rotate the shaft, whereas the rotating shaft 21 is provided as a member that can rotate around the fixed shaft 22. The carrier 14 is fixedly attached to the rotary shaft 21 via a fixture 21a, and rotates together with the rotary shaft 21 that is rotationally driven by a rotary drive device (not shown). Specifically, the conveyance body 14 rotates and moves intermittently together with the rotating shaft 21, and repeatedly performs a moving operation and a stopping operation.

  A pedestal 23 is fixed to the fixed shaft 22 via a fixture 22a. The pedestal 23 extends in the horizontal direction above the transport body 14 and does not rotate. A stand 80 for fixing the pedestal 23 is installed on the gantry 12. An air cylinder 24 is placed on the pedestal 23, and a first receiving member 26 is attached to the tip of the cylinder shaft 25 of the air cylinder 24. The first receiving member 26 changes the horizontal position (that is, the position in the first direction D1) according to the amount of expansion / contraction of the cylinder shaft 25.

  The first direction D <b> 1 here is a horizontal direction in which the transport body 14 extends, and particularly refers to a radial direction (that is, a radial direction) based on the rotation shaft 21 that is the rotation shaft of the transport body 14. In the following description, the radially outer side means the left side of FIG. 4, and the radially inner side means the right side of FIG. As will be described later, the thickness direction of the packaging bag 100 supported by the support portions (that is, the first side support portion 61, the second side support portion 62, and the intermediate support portion 63) coincides with the first direction D1. To do.

  A cushion pedestal 58 is attached to the lower surface of the pedestal 23, and a cushion 28 is attached to the tip of the cushion pedestal 58.

Accordingly, the position of the outer gripping member 47 in the first direction D1 varies according to the movement of the cam follower 37 in the first direction D1, and the distance between the inner gripping member 46 and the outer gripping member 47 constituting the intermediate support portion 63 is changed. change. Thereby, the gripping state of the packaging bag 100 by the inner gripping member 46 and the outer gripping member 47 also changes.

  A second receiving member 39 is provided on the upper surface of the slide plate 33, and the second receiving member 39 extends from the slide plate 33 upward in the vertical direction. A through hole 39a is formed in the second receiving member 39, and a guide shaft 42 extending in the first direction D1 is provided so as to penetrate the through hole 39a. A stopper 40 is provided on one end portion of the guide shaft 42 (right end portion in FIG. 4), particularly on the radially inner side of the second receiving member 39 (right side in FIG. 4). On the other hand, the other end portion (left end portion in FIG. 4) of the guide shaft 42 is fixed to the swing lever 43. The stopper 40 has a radial size larger than the diameter of the through hole 39a, and comes into contact with the second receiving member 39 in the first direction D1 of the guide shaft 42 (particularly radially outward (left side in FIG. 4)). Functions as a stopper that restricts the movement of the swing lever 43, the swing of the swing lever 43, and the movement of the abutting member 44.

  The guide shaft 42 is inserted into the first biasing spring 41. The first urging spring 41 is disposed in a compressed state between the overhanging portion attached to the other end of the guide shaft 42 and the second receiving member 39, and the swing lever 43 and the second receiving member 39. An urging force is applied to the swing lever 43 and the second receiving member 39 in the direction in which they are separated from each other.

  A swing lever 43 is provided on the upper surface of the slide plate 33 via a swing shaft 38, and an outer gripping member 47 is connected to the swing lever 43. The swing lever 43 is provided so as to be able to rotate together with the transport body 14 and swingable about the swing shaft 38. The elevating drive unit 70 (that is, the air cylinder 24, the cylinder shaft 25, and the first receiving member 26) can swing the swing lever 43. As the elevating drive unit 70 swings the swing lever 43, the outer gripping member 47 can be moved in the second direction D2.

  The second direction D <b> 2 here is a direction including a vertical direction component, and indicates a direction in which the outer gripping member 47 moves due to the swing of the swing lever 43. In the case of the structure in which the swing lever 43 rotates around the swing shaft 38 as in the present embodiment, the outer gripping member 47 can move so as to draw an arc orbit around the swing shaft 38.

  An abutting member 44 is provided at one end forming the top of the swing lever 43. The abutting member 44 is fixed to the swing lever 43 and swings together with the swing lever 43. The swing lever 43 includes a horizontal extending portion 74, a vertical extending portion 75, and an overlap portion 76. A vertical extending portion 75 is attached to one end portion (the right end portion in FIG. 4) of the overlap portion 76. On the other hand, an outer gripping member 47 and an outer opening / closing member 48 are provided at the other end portion (the left end portion in FIG. 1) of the overlap portion 76. The overlap portion 76 is the first seal device 19 and the second seal device 20 (especially, the seal portion (which is pressed against the packaging bag 100 and seals the bag mouth 105) in the above-described stations A8 and A9 (see FIG. 2). 16 and FIG. 17 (see reference numerals “143” and “144”)), and extends in the vertical direction, and is disposed at a position overlapping the first sealing device 19 and the second sealing device 20 in the vertical direction.

  Further, the block support member 45 has a vertically extending portion 77 and an overlap portion 78. The overlap portion 78 of the block support member 45 is also perpendicular to the first seal device 19 and the second seal device 20 (especially the seal portion) at the stations A8 and A9, similarly to the overlap portion 76 of the swing lever 43. It extends in the lower direction and is disposed at a position overlapping the first sealing device 19 and the second sealing device 20 in the vertical direction.

  One end portion of the block support member 45 (that is, the right end portion in FIG. 4) is fixedly attached to the base 31, and the other end portion (that is, the left end portion in FIG. 4) is the upper surface of the block 52. It is fixedly attached to. An inner gripping member 46 is fixedly attached to the upper surface of the block 52. Thus, the inner gripping member 46 is fixedly provided to the transport body 14 via the block 52, the block support member 45, and the base 31. Therefore, the inner gripping member 46 rotates together with the transport body 14, but is fixed without moving in the first direction D1 (that is, the left-right direction in FIG. 4).

  A hole for accommodating the second biasing spring 51 is formed inside the block 52. The block 52 is formed with a long hole portion 55 and a protruding port 59 that communicate the internal hole with the outside. The sliding shaft 50 extending in the first direction D1 extends in a hole in the block 52 and protrudes to the outside from the protruding port 59. The block 52 supports the sliding shaft 50 in a state in which it can advance and retract in the thickness direction of the packaging bag 100 (that is, the first direction D1). Therefore, the inner gripping member 46 fixedly provided to the block 52 is not fixedly connected to the slide shaft 50 provided separately from the block 52.

  A third receiving member 54 is integrally provided at one end of the slide shaft 50 (that is, the right end in FIG. 4). The third receiving member 54 extends downward in the vertical direction, and projects outward from the hole in the block 52 via the long hole portion 55. The third receiving member 54 moves in the first direction D1 together with the sliding shaft 50. The third receiving member 54 is urged by the second urging spring 51 disposed in the hole in the block 52, and the urging force is applied from the second urging spring 51 in the radially inward direction (that is, the right direction in FIG. 4). receive. A receiving member 53 is fixed to the third receiving member 54, and the receiving member 53 is fixed to the sliding shaft 50 via the third receiving member 54. The receiving member 53 resists the urging force of the second urging spring 51 by receiving a force from the pushing member (see reference numeral “133” in FIGS. 16 and 17 described later) from the right side to the left side in FIG. The third receiving member 54, the sliding shaft 50, and the inner opening / closing member 49 are moved to the left in FIG. That is, the inner opening / closing member 49, the sliding shaft 50, the third receiving member 54, and the receiving member 53 constitute an intermediate moving body 56 that moves integrally in the first direction D1. Even when the intermediate moving body 56 moves the outer opening / closing member 48 radially outward (left side in FIG. 4), the outer gripping member 47 is moved radially outward.

  In the bag filling and packaging machine 10 having the above-described configuration, the intermediate support portion 63 includes an inner gripping member 46 and an outer gripping member 47 that support the partitioning portion 104 of the packaging bag 100 with the partition 104 therebetween. That is, the partition 104 of the packaging bag 100 is gripped by the inner gripping member 46 and the outer gripping member 47. The inner gripping member 46 abuts on the first side surface 111 on the side close to the transport body 14 among the two side surfaces extending between the both side portions 103 of the packaging bag 100. The outer gripping member 47 abuts on the second side surface 112 on the side far from the transport body 14.

  16 and 17, which will be described later, the position of the part of the partition 104 of the packaging bag 100 that is supported by the intermediate support 63 (that is, the inner gripping member 46 and the outer gripping member 47) is It exists below the position of the part sealed by the sealing device (namely, the 1st sealing device 19 and the 2nd sealing device 20). That is, the lower part in the height direction (vertical direction) of the inner partition portion 104 in the height direction (vertical direction) than the planned seal portion in the vicinity of the upper edge of the packaging bag 100 set near the bag mouth 105 is the inner gripping member 46 and the outer gripping. It is gripped by the member 47.

  The intermediate support drive unit 68 includes a first advance / retreat drive unit 69 and a lift drive unit 70. The first advancing / retreating drive unit 69 moves the outer gripping member 47 in the first direction D1 including the horizontal direction component that is separated from and close to the second side surface 112. Specifically, the first advance / retreat drive unit 69 includes, for example, a first cam 27, a cam follower 37, a follower shaft 36, a bearing base 35, a slide plate 33, a swing shaft 38, and a swing lever 43. On the other hand, the raising / lowering drive part 70 moves the outer side holding member 47 to the 2nd direction D2 containing a vertical direction component. That is, when the packaging bag 100 is transferred from the bag feeder to the support unit 60 (that is, the first side support unit 61, the second side support unit 62, and the intermediate support unit 63) at the station A1, The outer gripping member 47 is moved above the bag feeder. Specifically, the elevating drive unit 70 includes an air cylinder 24 (including the cylinder shaft 25) and the first receiving member 26.

[Operation mechanism of intermediate support drive unit 68 and intermediate support unit 63]
Next, an operation mechanism of the above-described bagging and packaging machine 10 (particularly, the intermediate support driving unit 68 and the intermediate support unit 63) will be described.

  7-10 is a top view for demonstrating the action | operation mechanism of the bag filling packaging machine 10. FIG. 11 to 15 are side views for explaining an operation mechanism of the bag filling and packaging machine 10. 7 to 15 show only members relevant to the description in order to facilitate understanding.

<First state>
First, the first state will be described with reference to FIGS.

  In the first state, when the target support portion 60 (that is, the first side support portion 61, the second side support portion 62, and the intermediate support portion 63) moves from the station A10 to the station A1, the cam follower 37 is moved. By being in contact with the first cam 27, the carrier 14 is pushed outward in the radial direction. At this time, the compression spring 34 is compressed between the slide plate 33 and the rail 32. As a result, the cam follower 37, the follower shaft 36, the bearing base 35, the slide plate 33, the swing shaft 38, the swing lever 43, and the outer gripping member 47 move radially outward (left side in FIG. 11). A space is formed between the inner gripping member 46 and the inner gripping member 46.

  In this first state, the swing lever 43 does not swing, and the outer gripping member 47 fixed to the swing lever 43 does not move upward. The outer opening / closing member 48 moves radially outward together with the swing lever 43, and a space is formed between the outer opening / closing member 48 and the inner opening / closing member 49.

  Further, since the first state is a state immediately after the packaging bag 100 is discharged at the station A10, the new packaging bag 100 has not been supplied to the support unit 60 yet.

<Second state>
Next, the second state after the first state will be described with reference to FIGS.

  In the second state, the air cylinder 24 is operated to contract the cylinder shaft 25 to reduce the amount of projection of the cylinder shaft 25 from the main body, and the first receiving member 26 is in the radially inner side in contact with the abutting member 44. The abutting member 44 also moves radially inward. As a result, the swing lever 43 swings in the second direction D2 about the swing shaft 38, and the outer gripping member 47 and the outer opening / closing member 48 provided near the tip of the swing lever 43 move vertically upward. To do. As a result, the swing lever 43, the outer gripping member 47, and the outer opening / closing member 48 are all retracted from the supply position of the packaging bag 100, and interference with the bag supply device 81 can be avoided. During this time, the transport body 14 is stopped. Further, the contact of the abutting member 44 with the cushion 28 prevents the swing lever 43 from swinging excessively.

  Thus, the swing lever 43 swings in a state where the inner gripping member 46 and the outer gripping member 47 are separated from each other and the outer opening / closing member 48 and the inner opening / closing member 49 are spaced from each other. Therefore, even when the gripping surfaces of the inner gripping member 46 and the outer gripping member 47 and the gripping surfaces of the outer opening / closing member 48 and the inner opening / closing member 49 are made of a soft material such as rubber, these are not necessary when the swing lever 43 swings. The grip surfaces are not rubbed because they are not in contact with each other. Therefore, it is possible to smoothly swing the swing lever 43 without causing breakage or friction of these gripping surfaces. In the second state, the swing lever 43 swings against the biasing force of the first biasing spring 41, and the first biasing spring 41 is in a compressed state.

  After the swing lever 43, the outer gripping member 47, and the outer opening / closing member 48 are all retracted from the supply position of the packaging bag 100, the bag feeding device 81 is supported by the support unit 60 (that is, the first side support unit 61, the second side support unit 61, The packaging bag 100 is supplied to the side support part 62 and the intermediate support part 63). Specifically, each of the first side support part 61 and the second side support part 62 grips both side parts 103 of the packaging bag 100 supplied via the bag supply device 81.

  Although the packaging bag 100 supplied to the support portion 60 by the bag supply device 81 is disposed in contact with the inner gripping member 46, the outer gripping member 47 is disposed at a position retracted from the supply position. Therefore, in the second state described above, both side portions 103 of the packaging bag 100 are supported by the side support portions 61 and 62, but the partition 104 of the packaging bag 100 is still supported by the intermediate support portion 63. Absent.

<Third state>
Next, the third state after the second state will be described with reference to FIGS. 9 and 13.

  The third state is mainly a state during which the support portion 60 (that is, the first side support portion 61 and the second side support portions 62 and 63) moves from the station A1 to the station A2. In the third state, the contact member 44 moves from the first receiving member 26 to the fixed guide member 57 by the rotation of the transport body 14. The abutting member 44 is urged toward the fixed guide member 57 by the first urging spring 41 and moves while being in contact with the fixed guide member 57.

  The fixed guide member 57 is arranged along the movement track of the abutting member 44 while the support portion 60 moves from the station A1 to the station A2. One end of the fixed guide member 57 (the left end in FIGS. 8 and 9) is disposed at a position continuous with the first receiving member 26 in the second state. Accordingly, when the support portion 60 moves from the station A1 toward the station A2, the abutting member 44 can smoothly transition from the first receiving member 26 to the fixed guide member 57.

  Further, as the fixed guide member 57 rotates and the conveyance body 14 moves, the outer gripping member 47 and the outer opening / closing member 48 provided at the front end of the swing lever 43 gradually move downward in the vertical direction. It has a shape that can be done. That is, as the support portion 60 moves from the station A1 toward the station A2, the relative position of the fixed guide member 57 with respect to the swing shaft 38 that serves as a swing support point of the swing lever 43 changes from the radially inner side to the radially outer side. The fixed guide member 57 is arranged so as to move gradually toward the center. This prevents the swing lever 43, the outer gripping member 47, and the outer opening / closing member 48 from rapidly swinging downward in the vertical direction. It is possible to gradually return to the state 1 (see FIGS. 7 and 11).

  On the other hand, the cam follower 37 moves on the first cam 27. At this time, the first cam 27 adjusts the position of the cam follower 37 in the first direction D1 and controls the positions of the outer gripping member 47 and the outer opening / closing member 48 in the first direction D1. That is, as the swing lever 43 swings downward in the vertical direction, the outer gripping member 47 approaches the inner gripping member 46 and the outer opening / closing member 48 approaches the inner opening / closing member 49. At this time, the positions of the outer gripping member 47 and the outer opening / closing member 48 in the first direction D1 so that each of the outer gripping member 47 and the outer opening / closing member 48 passes a position away from the inner gripping member 46 and the inner opening / closing member 49. Is controlled. Accordingly, the outer gripping member 47 and the inner gripping member 46 do not interfere with each other, and the outer opening / closing member 48 and the inner opening / closing member 49 do not interfere with each other. Thus, in the third state, while the cam follower 37 is in contact with the first cam 27, the outer gripping member 47 does not contact the inner gripping member 46, and the outer opening / closing member 48 contacts the inner opening / closing member 49. do not do.

  As shown in FIG. 9, the cylinder shaft 25 of the air cylinder 24 provided in the station A1 is used for the next support portion 60 (particularly the contact member 44) that moves to the station A1, and the second shaft described above. The first state (see FIG. 7) is restored.

<Fourth state>
Next, the fourth state after the third state will be described with reference to FIGS.

  The fourth state is a state mainly from immediately before the support portion 60 reaches the station A2 to immediately before it reaches the opening station A4. In this fourth state, the stopper 40 comes into contact with the second receiving member 39 when the carrier 14 rotates and the support portion 60 approaches the station A2 to some extent, and the swing lever 43 swings (ie, tilts). Is limited, the contact member 44 is separated from the fixed guide member 57, and the contact member 44 is not in contact with the fixed guide member 57.

  On the other hand, the cam follower 37 is positioned in the first direction D1 by the first cam 27 in contact with the first cam 27, and between the inner gripping member 46 and the outer gripping member 47 and between the outer opening / closing member 48. A space is formed between the inner opening and closing member 49.

  Accordingly, the outer gripping member 47 is disposed at a position facing and separating from the inner gripping member 46 and the packaging bag 100, and the outer opening / closing member 48 is disposed at a position facing and spaced apart from the inner opening / closing member 49. The Thus, in the fourth state, the partition 104 of the packaging bag 100 is not supported by the intermediate support portion 63 (that is, the inner gripping member 46 and the inner opening / closing member 49). However, both side portions 103 of the packaging bag 100 are supported by the side support portions 61 and 62.

<Fifth state>
Next, the fifth state after the fourth state will be described with reference to FIG.

  The fifth state is a state mainly from immediately before the support unit 60 reaches the station A4 until the opening process reaches the opening station A4. In the fifth state, the cam follower 37 is separated from the first cam 27. As a result, the slide plate 33 is pressed radially inward (right side in FIG. 15) by the urging force of the compression spring 34, and the slide plate 33, the bearing base 35, the follower shaft 36, and the cam follower 37 move radially inward. As the slide plate 33 moves, the rocking shaft 38, the rocking lever 43, the outer gripping member 47, and the outer opening / closing member 48 fixed to the slide plate 33 also move radially inward. As a result, the outer gripping member 47 presses the inner gripping member 46 and the outer opening / closing member 48 contacts the inner opening / closing member 49. That is, the partition 104 of the packaging bag 100 is sandwiched and supported by the outer gripping member 47 and the inner gripping member 46.

  The position of the outer gripping member 47 in the first direction D1 is determined by the inner gripping member 46. When the inner gripping member 46 determines the position of the outer gripping member 47 in the first direction D1, other members fixed to the outer gripping member 47 (that is, the swing lever 43, the swing shaft 38, the slide plate 33, the bearing). The positions of the base 35, the follower shaft 36 and the cam follower 37) in the first direction D1 are also determined. Therefore, even if the cam follower 37 is not in contact with the first cam 27, the cam follower 37 is disposed at a predetermined position.

  When the packaging bag 100 is subjected to the opening process at the station A4 by passing through the first state to the fifth state described above, both side portions 103 are supported by the side support portions 61 and 62, and the partition is formed. The part 104 is supported by the intermediate support part 63.

  In particular, as shown in FIG. 12, since the packaging bag 100 is supplied with the swing lever 43 and the outer gripping member 47 retracted from the supply position, the swing lever 43 and the outer gripping member 47 are connected to the bag feeding device 81. Interference can be reliably prevented. Further, when the outer gripping member 47 moves vertically downward to support the partition 104 of the packaging bag 100 by the intermediate support portion 63, the outer gripping member 47 is kept away from the packaging bag 100. The A space is formed between the outer gripping member 47 and the packaging bag 100 and the outer gripping member 47 faces the packaging bag 100 (particularly the second side surface 112) with respect to the second side surface 112 of the packaging bag 100. Thus, the outer gripping member 47 moves in the first direction D1 (ie, the radially inner direction), which is a substantially vertical direction, and the outer gripping member 47 contacts the packaging bag 100. Thereby, it is possible to prevent the outer gripping member 47 from rubbing against the packaging bag 100 (particularly the second side surface 112), and the packaging bag 100 is wrinkled or the gripping surface (for example, rubber) of the outer gripping member 47 is damaged. Can be avoided.

  As described above, according to the bagging and packaging method of the present embodiment, the support unit that moves the packaging bag 100 having a plurality of storage chambers (that is, the first storage chamber 101 and the second storage chamber 102) together with the transport body 14. 60, a step of passing from the bag supply device 81, a step of supporting the both side portions 103 of the packaging bag 100 by the side support portions 61 and 62, and a storage chamber (ie, a first chamber) provided adjacent to the packaging bag 100. A step of supporting the partition 104 between the first storage chamber 101 and the second storage chamber 102) by the intermediate support portion 63 is performed. In the step of supporting the partition 104, the inner gripping member 46 contacts the first side surface 111 on the side close to the transport body 14, and the outer gripping member 47 contacts the second side surface 112 on the side far from the transport body 14, When the inner gripping member 46 and the outer gripping member 47 sandwich the partition 104, the partition 104 is supported. In the process of passing the packaging bag 100 from the bag feeding device 81 to the support unit 60, the packaging bag 100 is moved from the bag feeding device 81 to the support unit 60 with the outer gripping member 47 disposed above the bag feeding device 81. Passed to. Further, the first advancing / retreating drive unit 69 moves the outer gripping member 47 in the direction away from the second side surface 112 in the first direction D1, and thereafter, the lifting / lowering driving unit 70 grips the outer gripping upward in the second direction D2. By moving the member 47, the outer gripping member 47 is disposed above the bag feeding device 81. Further, the elevating drive unit 70 moves the outer gripping member 47 disposed above the bag feeding device 81 downward in the second direction D2, and the outer gripping member 47 is disposed at a position away from the second side surface 112. Then, the outer gripping member 47 is brought into contact with the second side surface 112 by moving the outer gripping member 47 in the direction closer to the second side surface 112 in the first direction D1 by the first advance / retreat driving unit 69. Can do.

Press radially outward. Note that a control unit (not shown) is connected to the air cylinder 130, and the expansion / contraction amount of the air cylinder shaft 131 is changed by the control unit. The control unit holds information on whether or not the packaging bag 100 disposed at the forced discharge location (that is, station A8 in this example) is a defective bag. If the packaging bag 100 is a defective bag, the control unit controls the air cylinder shaft 131. If the packaging bag 100 is not defective, the air cylinder shaft 131 is maintained in a contracted state.

  When the air cylinder shaft 131 is extended, the receiving member 53 is pressed by the pressing plate 133, the entire intermediate moving body 56 moves radially outward, and contacts the inner opening / closing member 49, the outer opening / closing member 48. The swing lever 43 fixed to the swing lever 48 and the outer gripping member 47 fixed to the swing lever 43 also move radially outward. That is, the sliding shaft 50 is moved radially outward in accordance with the operation of the air cylinder 130 serving as a driving source, and the inner opening / closing member 49 is moved radially outward while being engaged with or in contact with the outer opening / closing member 48. Thus, the outer gripping member 47 can be moved radially outward. Accordingly, the outer gripping member 47 is separated from the inner gripping member 46, and the support in the partition 104 of the packaging bag 100 is released. At the same timing, the support of the packaging bag 100 by the side support portions 61 and 62 is also released by the control unit. Thereby, the packaging bag 100 is released from the support by the support part 60 (that is, the first side support part 61, the second side support part 62, and the intermediate support part 63), and falls downward.

  Thus, in this embodiment, according to the action | operation of the air cylinder 130, the support and non-support of the partition part 104 by the intermediate | middle support part 63 (namely, the inner side holding member 46 and the outer side holding member 47) can be switched. Therefore, such defective bags can be discharged by operating the air cylinder 130 and extending the air cylinder shaft 131 only when the packaging bag 100 being conveyed is a defective bag. On the other hand, if the packaging bag 100 being conveyed is not a defective bag, the air cylinder shaft 131 may be held in a contracted state without operating the air cylinder shaft 131.

  Note that while the defective bag is being discharged, the first sealing device 19 is disposed above the swing lever 43 in the vertical direction, so that the swing lever 43 can be swung upward in the vertical direction. Can not.
