U.S. Pat. No. 6,834,481

  By the way, a plurality of pouch containers filled with contents such as shampoo, rinse, treatment, detergent, and softener are bundled together by a heat-shrinkable tubular film to a soft packaging material made of a flexible sheet. Can be considered. In this case, the pouch container is different from the bottle container (for example, a glass or PET bottle) described in Patent Document 1 described above, but has a self-supporting property but is easily deformed. Therefore, a device for fitting a heat-shrinkable tubular film in order to bind and bind a plurality of such pouch containers together requires a device for stably performing the film fitting operation.

  An object of the present invention is to stably fit a heat-shrinkable tubular film for bundling a plurality of pouch containers made of a flexible sheet material around a plurality of pouch containers to be bundled. It is an object of the present invention to provide a film-fitting device that can be used and a manufacturing system of a pouch container bundle including the same.

  A film-fitting device according to one embodiment of the present invention is a heat-shrinkable tubular film for bundling a plurality of pouch containers in which contents are hermetically filled in a soft packaging material made of a flexible sheet material. Is a film fitting device for fitting around the plurality of pouch containers, wherein the contents are moved to the upper part of the body portions by pressing the body portions of the plurality of pouch containers arranged side by side. A clamp member; and a film fitting head for fitting the tubular film around the body from above the body portion around the plurality of pouch containers pressed by the clamp member.

  According to this configuration, by pressing the body of the pouch container with the clamp member and moving the contents to the upper part of the body, the upper part of the body of the pouch container is expanded and the body sheet material is stretched. be able to. Thereby, the upper part of each trunk of the plurality of pouch containers arranged adjacent to each other is hardly deformed. Therefore, in a state where the heat-shrinkable tubular film is opened, it becomes possible to stably fit the periphery of the plurality of pouch containers to be bound from above.

  In the film-fitting device according to the present invention, the film-fitting head has a pair of guide members parallel to each other that are guided to be fitted around the plurality of pouch containers in a state where the cylindrical film is opened. The width of each guide member in the horizontal direction may be set to be larger than the length of the top seal portion of the body of the pouch container.

  According to this configuration, since the horizontal width of the pair of guide members included in the film-embedded head is set to be larger than the length of the top seal portion of the pouch container to be bound, the pair of guide members are opened by the pair of guide members. The tubular film can be fitted around the plurality of pouch containers without being caught on the top seal portion of the pouch container.

  In this case, the top seal portion of the pouch container includes a horizontal portion and an inclined portion inclined downward from an end of the horizontal portion, and the width of each of the guide members in the horizontal direction is the horizontal width of the top seal portion. It is preferable that the length is set larger than the length of the portion.

  According to this configuration, the horizontal width of the pair of guide members included in the film-embedded head is set to be larger than the length of the horizontal portion of the top seal portion of the pouch container to be bound. The tubular film opened by the above can be fitted around the plurality of pouch containers without being caught on the horizontal portion of the top seal portion of the pouch container. In this case, even if the lower end of the cylindrical film comes into contact with the downwardly inclined portion of the top seal portion of the pouch container, the tubular film can be moved downward while being guided by the inclined portion. The tubular film does not get caught.

  Further, in the film-fitting device of the present invention, the film-fitting head is provided at a constant pitch in a circumferential direction on a base that rotates above a film-fitting position at which the cylindrical film is fitted to the plurality of pouch containers. A plurality may be mounted, and each of the film-fitted heads may be configured in an index system in which the film-fitting head circulates and moves between the film-fitting position and the film receiving position for receiving the tubular film by rotating the base. .

  In this case, when the tubular film is received at the film receiving position, the pair of guide members move to a position close to each other and enter a receiving state, and the cylindrical member is moved from the film receiving position to the film fitting position. The pair of guide members may be moved to positions separated from each other so as to be in an open state so that the film is maintained in an open state without loosening.

  According to this configuration, when the pair of guide members receive the tubular film, they move to positions close to each other, so that the tubular film can be reliably received around the outside thereof. Also, until the pair of guide members receiving the tubular film move from the film receiving position to the film-fitting position by rotation of the base, the tubular film is maintained in an open state without loosening. Are moved to positions separated from each other. Accordingly, it is possible to reliably prevent the cylindrical film from moving in the circumferential direction around the pair of guide members.

  Further, in this case, when the tubular film is sent out from the pair of guide members by the sending member at the film-fitting position, the pair of guide members are in an open state in which the cylindrical film around the pair is loose. May be moved in a direction approaching each other to be in a sending state.

  According to this configuration, the pair of guide members move in the direction in which the pair of guide members approach each other at the film fitting position, and the tubular film is in an open state with slack, so that the tubular member is sent out by the delivery member to the pair of guide members. Easier to send out.

  Further, in the film fitting device of the present invention, when the pair of guide members move in a direction approaching each other at the time of sending out the cylindrical film at the film fitting position, between the lower end portions of the pair of guide members. The upper portions of the body portions of the plurality of pouch containers may be pinched in the direction in which the containers are lined up to be in a pinched state.

  According to this configuration, when the film is fitted, the pair of guide members move in the direction approaching each other, and the upper body portions of the plurality of pouch containers are sandwiched between the lower end portions of the guide members in the direction in which the containers are arranged. The thickness of the plurality of pouch containers in the direction in which the containers are arranged is reduced. Thereby, when the open tubular film is fitted, it is hard to be caught by the top seal portion of the pouch container, and the film fitting operation can be stably performed. In addition, since the lower ends of the pair of guide members contact the upper portions of the body of the plurality of pouch containers on both sides in the direction in which the containers are arranged, the tubular film sent from the guide members surely transfers to the pouch containers. As a result, the film fitting operation can be performed more stably.

  Further, in the film fitting apparatus of the present invention, the film fitting head including the pair of guide members may be a film fitting position for fitting the tubular film around the plurality of pouch containers arranged in a line. The lower end portions of the two inclined guide portions of the V-shaped inclined shaping member are fixedly arranged at a fixed position with respect to the lower end portion, and are respectively connected to the upper end portions of the pair of guide members. When the cylindrical film fitted on the upper end of the inclined shaping member is conveyed downward along the inclined guide portion of the inclined shaping member by a belt or a roller abutting on an outer peripheral surface of the film, the cylindrical film A film-shaped opening is formed and supplied around the pair of guide members, and is directed from the pair of guide members to the plurality of pouch containers by a roller or a belt abutting on the outer peripheral surface of the film. It may be constituted by inclined guide system delivered.

  According to this configuration, since the film-fitted head including the pair of guide members is fixedly arranged with respect to the film-fitted position, there is no need to rotate and move the base on which the plurality of film-fitted heads are mounted. Thus, the configuration can be simplified.

  A manufacturing system of a pouch container bundle according to another embodiment of the present invention is a method in which a plurality of pouch containers whose contents are hermetically filled in a soft wrapping material made of a flexible sheet are grouped by a heat-shrinkable tubular film. A manufacturing system for a bundled pouch container binding body, wherein a film-fitting device having any one of the above-described configurations and a plurality of pouch containers are sequentially conveyed in a line to a film-fitting position in the film-fitting device. A container conveying device, and a heating device that thermally shrinks the tubular film by passing the plurality of pouch containers fitted with the tubular film at the film fitting position by the film fitting device. .

  According to this configuration, it is possible to continuously and stably produce a pouch container bundle united by the heat-shrinkable tubular film.

  In the pouch container bundle manufacturing system of the present invention, after passing through the heating device, a seal member is stuck over the tubular film binding the plurality of pouch containers and the body of the plurality of pouch containers. The apparatus may further include a seal sticking device.

  According to this configuration, since the seal member is stuck over the tubular film and the body of the plurality of pouch containers, it is ensured that the plurality of pouch containers come off from the tubular film after the heat shrinkage. Can be prevented.

  ADVANTAGE OF THE INVENTION According to the film embedding apparatus which concerns on this invention, the heat-shrinkable cylindrical film for bundling a plurality of pouch containers which are flexible and easy to deform reliably is covered around the several pouch containers to be bundled.

When a plurality of embodiments and modified examples are included below, it is assumed from the beginning that the characteristic portions are appropriately combined and used.

  FIG. 1 is a schematic plan view showing an overall configuration of a manufacturing system 10 for a bundle of pouch containers according to an embodiment of the present invention, as viewed from above. The manufacturing system 10 for a pouch container bundle includes a container alignment device 12, a film fitting device 14, a film supply device 16, a heating device 18, and a seal sticking in order from the upstream side along the container conveyance direction indicated by the arrow A. An apparatus 20 is provided. The pouch container C and the pouch container bundle B described with reference to FIGS. 2 and 3 are conveyed in the direction of arrow A by the first conveyor 22, the second conveyor (container conveying device) 24, and the third conveyor 26, It is configured such that the pouch container bundles B are sequentially supplied from the third conveyor 26 onto the work table 28. Details of each of the above devices 12 to 26 will be described later.

  FIG. 2 is a perspective view of a pouch container C used in the present embodiment, and FIG. 3 is a perspective view showing a pouch container bundle B in which two pouch containers C are bound by a tubular film F.

  Referring to FIG. 2, the pouch container C is a soft wrapping material formed of a flexible sheet material, and the contents are hermetically filled therein. The contents of the pouch container C are not particularly limited, and include various care products for daily use such as shampoo, rinse, treatment, detergent, softener, and drinks such as sports drinks. The content is not limited to a liquid, but may be a viscous substance or a powdery substance.

  The pouch container C includes a top sheet 31 and a back sheet 32 that are a pair of body sheets, a bottom sheet 33, and a top sheet 34. The top sheet 31 and the back sheet 32 are sheet materials forming the front and back portions of the container, respectively. The bottom sheet 33 is folded and inserted between the top sheet 31 and the back sheet 32. In the pouch container C, the bottom sheet 33 is unfolded and becomes self-supporting by filling the contents. The top sheet 34 is a sheet material that forms an upper surface portion of the container that has a spread.

  The pouch container C has, between the superposed top sheet 31 and the back sheet 32, a seal portion that joins the edges of each sheet material in a state where the bottom sheet 33 is inserted from the lower end side. It has a structure in which the filling portion 37, which is the space inside the container to be filled, is sealed. The upper end of the filling section 37 is hermetically sealed by joining the top sheet 34 to the top edges of the top sheet 31 and the back sheet 32.

  Each of the top sheet 31 and the back sheet 32 has a substantially rectangular shape extending slightly vertically in the vertical direction. The bottom sheet 33 also has a substantially rectangular shape in a state where the bottom sheet 33 is developed by filling the contents. The top sheet 34 has a substantially hexagonal shape and is provided at the upper ends of the top sheet 31 and the back sheet 32. The top sheet 34 is not limited to a substantially hexagonal shape, and may be, for example, another polygonal shape such as a quadrangle or an octagon, or a shape such as a circle, an ellipse, or a rhombus. There may be.

  The sheet material forming each of the sheets 31 to 34 is a sheet-like member constituting the wall portion of the pouch container C, and is usually formed of a resin film. The resin film constituting the sheet material is required to have basic performance as a package, such as impact resistance, abrasion resistance, and heat resistance. The thickness of the sheet material is, for example, 10 μm to 300 μm, and preferably 20 μm to 200 μm. Further, since the seal portion is usually formed by heat sealing, the sheet material is also required to have heat sealability. As the sheet material, a multi-layer sheet material having a base film layer and a sealant layer for imparting heat sealability is preferable, and when high gas barrier properties are required, a sheet between the base film layer and the sealant layer is preferably used. It is preferable to provide a gas barrier layer on the substrate.

  It is preferable that the seal portion at the edge portion of each of the sheets 31 to 34 is formed by heat sealing. The seal part by heat sealing can be formed by overlapping and thermocompression bonding so that the sealant layer of each sheet material is inside the container. The pouch container C has a top seal part 38, a bottom seal part 39, and a side seal part 40 as the seal part. The top seal portion 38 is a seal portion formed in a substantially hexagonal frame shape at the edge of the top sheet 34, and includes the outer peripheral edge of the top sheet 34 and each upper end of the top sheet 31 and the back sheet 32. Are joined together.

  When the pouch container C is free standing on a horizontal plane, the top seal portion 38 includes a horizontal portion 38a extending substantially along the horizontal direction, and an inclined portion 38b extending downward from both ends of the horizontal portion 38a. Including. The bottom seal portion 39 is a seal portion formed at an edge of the bottom sheet 33, and is formed by joining the bottom sheet 33 with the top sheet 31 and the back sheet 32.

  The side seal portions 40 are formed at both ends in the width direction by directly joining the width direction edges of the top sheet 31 and the back sheet 32 to each other. The side seal part 40 is an edge seal part for sealing the filling part 37 like other seal parts. The side seal portion 40 is formed by extending along the vertical direction or the height direction of the container.

  In the pouch container C, a plug 42 for filling and taking out the contents is provided at the center of the top sheet 34. The spout 42 includes a spout 43 fixed to the top sheet 34 and a cap 44 screwed into a screw formed on the outer periphery of the spout 43.

  The spout 43 has a tubular portion 43a that protrudes outward from the top sheet 34, and a flange portion 43b that is integrally formed at an end of the tubular portion 43a. The flange portion 43b has a substantially rectangular shape, and is attached to the inner surface of the top sheet 34 (that is, the surface on the side of the filling portion 37) by, for example, heat sealing. The shape of the flange portion 43b is not limited to a substantially rectangular shape, and may be another shape such as a circle, an ellipse, an oval, and a polygon.

  When the filling portion 37 of the pouch container C is filled with the contents from the spout 43 and hermetically sealed, the bottom sheet 33 is expanded and spread, the top sheet 31 and the back sheet 32 are separated from each other, and the trunk is expanded. Form. Thereby, the pouch container C has autonomy. Since the top sheet 34 is provided on the pouch container C, the upper part of the pouch container C also expands as shown in FIG. However, since the pouch container C is formed of a flexible sheet material, when the filling portion 37 constituted by the top sheet 31 and the back sheet 32 is pushed from the outside, the pouch container C easily deforms due to the movement of the contents.

  As shown in FIG. 3, the pouch container bundle B is a unit in which two pouch containers C having the above-described configuration are united by a heat-shrinkable tubular film F in a state where two pouch containers C are arranged. In the example shown in FIG. 3, the top sheet 31 of one pouch container C and the back sheet 32 of the other pouch container C are bound in a state of contact.

  The tubular film F is formed from a heat-shrinkable film. Therefore, the tubular film F before heat shrinkage is fitted around the two side-by-side pouch containers C, and then the tubular film F is shrunk by heating so that the cylindrical film F is in close contact with the body of the pouch container C. can do. Thereby, the two pouch containers C are united by the fastening force (or binding force) of the tubular film F.

  The entirety of the tubular film F may be made of a heat-shrinkable film. Alternatively, the cylindrical film F may be configured such that a part in the circumferential direction is formed of a heat-shrinkable film and the other part in the circumferential direction is formed of a non-heat-shrinkable film. As the heat-shrinkable film, for example, a film made of a polyethylene-based resin, a polypropylene-based resin, or the like can be used as a single layer or a multilayer. As the non-heat-shrinkable film, for example, a stretched film or a non-stretched film of a polyester resin, a polyolefin resin, or the like can be used. When the heat-shrinkable film is used in a part of the circumferential direction of the tubular film F, the heat-shrinkable film portion is oriented in a direction orthogonal to the direction in which the two pouch containers C to be bound are arranged. It is preferable to arrange two cylindrical films F around the pouch container C in which two are arranged. Thereby, since the heat-shrinkable film portion is located between the side seal portion 40 of the one pouch container C and the side seal portion 40 of the other pouch container C, the heat-shrinkable film portion is contracted. In addition, wrinkles are less likely to be formed on the body sheets 31 and 32 facing the outside of the pouch container C, and it is possible to suppress the deterioration of the appearance of the pouch container bundle B.

  In the present embodiment, the axial length of the cylindrical film F is set so as to cover substantially the entire body height of the pouch container C. However, the present invention is not limited to this, and the axial length of the tubular film F may be formed shorter than the length of the body of the pouch container C, and a part of the body may be covered. Alternatively, the length of the tubular film F may be formed to be longer than the length of the trunk of the pouch container C, and may be applied to the peripheral portion of the top sheet 34 by heat shrinkage.

  Further, it is preferable to provide a design display section 45 on the outer peripheral surface of the tubular film F, on which a product name, a logo mark or the like when the pouch container C filled with the contents is sold is displayed. The design display section 45 is preferably provided at a circumferential position facing a side orthogonal to the direction in which the two pouch containers C are arranged. As shown in FIG. 3, when the bundled pouch container bundle B is displayed on a product shelf and sold, if the design display unit 45 is displayed with the front side, two pouch containers C are sold as a set. This has the advantage of making it easier for consumers to see. However, the design display section may be omitted, and the tubular film F is made of a transparent film, and the product name, logo mark, product description, bar code, etc. displayed on the body sheets 31, 32 of the pouch container C. May be visually recognized as it is.

  Subsequently, a description will be given of a manufacturing system 10 for manufacturing the above-described pouch container bundle B. First, the container alignment device 12 in the manufacturing system 10 will be described with reference to FIG. 4 in addition to FIG. FIG. 4 is a plan view partially showing the container alignment device 12. In FIG. 4, the illustration of the worker O shown in FIG. 1 is omitted.

  As shown in FIGS. 1 and 4, the container aligning device 12 includes a first conveyor 22 that places the pouch container C and transports the pouch container C in a direction indicated by an arrow A, and a pair of the first conveyor 22 disposed on both sides of the first conveyor 22. And a container alignment belt 46. The first conveyor 22 is constituted by an endless belt circulated by a motor (not shown).

  The container alignment belt 46 has an endless belt 49 that wraps around the pulleys 47 and 48 and circulates, and a number of claw members 50 and 51 attached to the belt 49 by, for example, screwing. The belt 49 is driven to rotate at the same speed as the first conveyor 22 by the motor 13 shown in FIG.

  The claw members 50 and 51 attached to the belt 49 have a curved shape so as to contact along the bulging trunk sheets 31 and 32 of the pouch container C. In addition, a partition plate 52 extending along the container transport direction A is disposed between the pair of container alignment belts 46. The height of the partition plate 52 can be set to, for example, about half the height of the trunk of the self-standing pouch container C.

  As shown in FIG. 1, workers O located on both sides of the container aligning device 12 insert and arrange the pouch container C from above between the partition plate 52 and the claw members 50 and 51 attached to the belt 49. . As a result, on the first conveyor 22, the two pouch containers C are aligned in a direction orthogonal to the container transport direction A, and are arranged at predetermined intervals along the container transport direction A. Then, the first conveyor 22 and the pair of belts 49 are driven to rotate at the same speed, so that the two pouch containers C arranged in a line are kept at a predetermined interval and are transferred to the second conveyor 24 of the film fitting apparatus 14. Supplied.

  Next, the film fitting device 14 will be described with reference to FIGS. 5 to 7 in addition to FIG. FIG. 5 is a plan view showing a clamp member of the film fitting device 14.

  As shown in FIGS. 1 and 5, the film fitting device 14 includes a second conveyor 24. The second conveyor 24 is constituted by an endless belt that is intermittently driven to rotate by a motor (not shown). The second conveyor 24 has a function of sequentially receiving two pouch containers C supplied from the first conveyor 22 included in the container alignment device 12 and sequentially transporting the two pouch containers C to the film fitting position α by intermittent driving. . Here, the moving direction of the second conveyor 24 (that is, the container transport direction A) is orthogonal to the direction in which the two pouch containers C are arranged.

  As shown in FIG. 1, a long band-like film base material FM in which a tubular film unwound from a reel included in a film supply device 16 is folded into a sheet shape is supplied to the film fitting device 14. Then, the film base FM is cut into a predetermined length by a cutting device (not shown). Thereby, a tubular film F for binding two pouch containers C is formed. Any known configuration may be used for the cutting device and the mechanism for transporting the cut and formed individual cylindrical films F to the film receiving position β (see FIG. 6).

  As shown in FIG. 5, the film fitting device 14 has a pair of clamp members 53 disposed on both sides of the second conveyor 24. Each clamp member 53 is connected via a rod 54 to a lever 55 that is swung in the directions of arrows D and E by a motor (not shown). Each clamp member 53 is installed on a guide member 56 having a rail (or groove) 57 on its surface, and is supported movably along the rail 57 in a direction orthogonal to the container transport direction A. Thus, when the lever 55 rotates in the direction of arrow D, the pair of clamp members 53 move closer to each other so as to protrude above the second conveyor 24, and move away from each other when the lever 55 rotates in the direction of arrow E. It is configured to return to the state shown in FIG.

  Each of the clamp members 53 has a plurality of concave portions 58 on a side portion on the second conveyor 24 side. In the present embodiment, an example in which five concave portions 58 are formed in each clamp member 53 is shown. The recess 58 located in the middle of the five recesses 58 with respect to the container transport direction A corresponds to a film fitting position α at which the two cylindrical films F are fitted to the pouch container C arranged in two rows.

  Each recess 58 is formed as a substantially trapezoidal depression so as to easily accommodate the swollen body of the pouch container C. Further, the recesses 58 are opposed to each other with the second conveyor 24 interposed therebetween. Further, in each of the recesses 58, the interval between the substantially trapezoidal recesses 58 is set to be the same as the interval in the container transport direction A of the two pouch containers C transported by the second conveyor 24.

  When the second conveyor 24 is intermittently driven and the two pouch containers C arranged at positions facing the recesses 58 are stopped, the lever 55 moves in the direction of arrow D. As a result, the two pouch containers C are clamped at the center in the height direction of the body of the pouch container C by the concave portions 58 of the clamp members 53 from both sides in the container arrangement direction. Then, the two pouch containers C are reliably held in the upright state, and the contents move to the upper part of the trunk by pressing the center part of the trunk. As a result, the upper portions of the body portions of the two pouch containers C arranged adjacent to each other are in a stretched state, so that the pouch containers C are hardly deformed. Thereby, as described later, it becomes possible to stably fit the heat-shrinkable tubular film F around the two pouch containers C to be bound at the film fitting position α from above. .

  Note that, in the present embodiment, an example is shown in which the concave portion 58 of the clamp member 53 is formed as a substantially trapezoidal depression, but the present invention is not limited to this. The shape of the concave portion 58 may be other shapes, such as a rectangular shape, a semicircular shape, and a triangular shape, depending on the body shape of the pouch container C. Further, the present invention is not limited to the case where a plurality of recesses 58 are formed in each clamp member 53. For example, only one recess may be formed in each clamp member 53 corresponding to the film fitting position α. . Even in this case, the film fitting operation can be stably performed on the two pouch containers C arranged at the film fitting position α.

  Subsequently, the film-fitting head provided in the film-fitting device 14 will be described with reference to FIGS. FIG. 6 is a perspective view showing four film-fitting heads 60 mounted on the disc-shaped base 59 in the film-fitting device 14. FIG. 7 is a perspective view showing one film-fitted head 60 in FIG. 6 without a cover.

  As shown in FIG. 6, the film-fitting device 14 includes a plurality of film-fitting heads 60 mounted on a disc-shaped base 59. The disc-shaped base 59 is driven to rotate at a predetermined angle in the direction of arrow G by a drive mechanism (not shown).

  In the present embodiment, four film-fitted heads 60 are mounted on the disc-shaped base 59 at a 90-degree pitch. Then, in each of the film-embedded heads 60, the disc-shaped base 59 is rotated and stopped every 90 degrees around the rotation center axis H. As a result, the two film-fitted heads 60 arranged radially opposite to each other are circulated between a film-fitted position α, which is a vertically lower position, and a film-receiving position β, which is a vertically upper position. It consists of a system.

  Each film-fitted head 60 has a pair of guide members 62a, 62b. The pair of guide members 62a and 62b are arranged to face each other in parallel with each other. Here, the facing direction of the pair of guide members 62a and 62b matches the arrangement direction of the two pouch containers C in which the tubular film F (see FIG. 3) is fitted. Each film-fitted head 60 is covered by a cover member 61 that opens radially outward, and a pair of guide members 62a and 62b extend radially outward from the opening of the cover member 61. . Since the film-fitting heads 60 have the same configuration, the configuration will be described in detail below with reference to FIG. 7 using the film-fitting head 60 facing the film-fitting position α as an example.

  The horizontal width of each of the guide members 62a and 62b is set to be larger than the length of the horizontal portion 38a of the top seal portion 38 of the pouch container C. Thereby, when the cylindrical film F held in an open state around the pair of guide members 62a and 62b is fitted to the two pouch containers C arranged side by side, the lower end portion of the cylindrical film F is It can be effectively prevented from being caught on the horizontal portion 38a.

  As shown in FIG. 7, the pair of guide members 62a and 62b in the film-fitted head 60 are preferably formed of, for example, a metal plate such as a stainless plate. The upper portions of the pair of guide members 62a and 62b are slidably supported by the top plate member 63, respectively. Specifically, the pair of guide members 62a and 62b are provided movably in a direction approaching each other as indicated by an arrow I and in a direction separating from each other as indicated by an arrow J.

  A lever 65 is rotatably provided on the top plate member 63. Brackets 64a and 64b to which guide members 62a and 62b are attached are connected to both ends of the lever 65 via cam followers. A drive rod 69 that moves in the direction of arrow M is rotatably connected to one end of the lever 65. With this configuration, when the drive rod 69 is driven in a direction in which it is pushed out from the disc-shaped base 59, the guide members 62a and 62b move in directions approaching each other by the rotation of the lever 65, and are driven. When the rod 69 is driven in a direction in which the rod 69 is pulled toward the disc-shaped base 59, the guide members 62a and 62b move in a direction away from each other. The drive rod 69 for moving the pair of guide members 62a and 62b can be driven by a cam (not shown).

  The top plate member 63 supporting the pair of guide members 62a and 62b is attached to the attachment member 66 at the end on the disk-shaped base 59 side. The mounting member 66 can move up and down in the direction of arrow K (that is, in the vertical direction) along two guide rails 67 fixed to the disk-shaped base 59.

  In addition, it is preferable that a clip 68 is provided on at least one outer surface of the pair of guide members 62a and 62b. The distal end of the clip 68 forms a wedge-shaped gap with the outer surface of the guide member 62a. As described later, when the tubular film F is received around the pair of guide members 62a and 62b at the film receiving position β, the clip 68 rotates in the direction of the arrow L, and the tubular film F is guided by the guide member 62a. Can be sandwiched between. Thereby, when the tubular film F fitted around the pair of guide members 62a and 62b is opened at the film receiving position β, the tubular film F can be held so as not to shift in the circumferential direction. .

  Next, a film fitting operation in the film fitting device 14 will be described with reference to FIGS. FIGS. 8 (a) to 8 (f) show stepwise how the disc-shaped base 59 rotates and the pair of guide members 62a, 62b of the film-fitting head 60 move from the film receiving position β to the film-fitting position. FIG.

  First, as shown in FIG. 8 (a), a vertically fitted film-fitted head 60 is cut into a predetermined length from a film base material FM (see FIG. 1) by a cutting device (not shown) and supplied to a cylindrical shape. The film F is received in a state of being fitted around the pair of guide members 62a and 62b. At this time, since the guide members 62a and 62b are in the receiving state in which they have moved to the positions closest to each other, it is possible to reliably receive the cylindrical film F that is opened in a substantially boat shape.

  When the tubular film F is received around the pair of guide members 62a and 62b in this manner, the clip 68 is driven by, for example, an air cylinder or the like as shown by an arrow N in FIG. 8B. Thus, the tubular film F is pressed against the guide member 62a by the clip 68.

  In this state, the disc-shaped base 59 rotates by 90 degrees in the direction of arrow G. During this rotation, the pair of guide members 62a and 62b move in the direction away from each other and become open. As a result, the cylindrical film F is opened without slack in a substantially rectangular parallelepiped shape around the pair of guide members 62a and 62b.

  As shown in FIG. 8C, a film pushing device 70 is disposed at a position shifted by 90 degrees from the film receiving position β so as to face the film fitting head 60 radially outward. . Then, as shown in FIG. 8D, when the film pushing device 70 is driven in the direction of the arrow P, the opened tubular film F is positioned on the back side (that is, the pair of guide members 62a and 62b). (The rotation center axis H side of the disc-shaped base 59). At this time, the grip of the tubular film F is once released by the opening of the clip 68 in the arrow Q direction. By shifting the holding position of the tubular film F with respect to the pair of guide members 62a, 62b in this manner, the leading ends of the guide members 62a, 62b project from the ends of the open tubular film F. Become.

  Thereafter, as shown in FIG. 8 (e), the film pushing device 70 returns to the original position, and the clip 68 closes in the direction of arrow N to return to a state where the tubular film F is pressed against the guide member 62a. Then, from this state, as shown in FIG. 8 (f), when the disc-shaped base 59 is further rotated by 90 degrees, the cylindrical film F held by the pair of guide members 62a, 62b is held at the film fitting position. It is conveyed above the two pouch containers C arranged by α. At this time, the two pouch containers C are clamped by the clamp members 53. At this time, in the film-fitting head 60 at the film-fitting position α, a new tubular film F is received around a pair of guide members 62a and 62b closed in a state of approaching each other.

  Next, the film fitting operation at the film fitting position α will be described in detail with reference to FIGS. FIGS. 9A to 9D are views showing stepwise how the tubular film F is fitted around two pouch containers arranged side by side at the film fitting position α. 9A to 9D include a front view shown on the left side, a side view shown on the right side, and a plan view shown on the upper side, respectively. FIG. 10 is a front view showing a state in which the cylindrical film F is scraped down from the pair of guide members 62a and 62b to the periphery of the two pouch containers C and is fitted at the film fitting position α. It is a left side) and a side view (right side). 9 and 10, the cylindrical film F is indicated by oblique hatching, and the clamp member 53 is indicated by cross hatching.

  As shown in FIG. 9A, the two pouch containers C conveyed by the second conveyor 24 (see FIG. 5) temporarily stop at the film fitting position α. Then, in the two pouch containers C, the clamp member 53 moves in the arrow R direction. As a result, the two pouch containers C are clamped by the clamp members 53 in the vicinity of the center of the trunk from both sides in the container arrangement direction, as shown in FIG. 9B. In each of the pouch containers C thus clamped, the contents move to the upper part in the body, so that the upper part of the body of each pouch container C is in an expanded state and is less likely to be deformed.

  Next, as shown in FIG. 9C, the pair of guide members 62a and 62b holding the tubular film F in an open state without loosening slightly move down. At this time, it is preferable that the tip positions of the guide members 62a and 62b be lowered to a position slightly lower than the horizontal portion 38a (see FIGS. 2 and 3) of the top seal portion 38 of each pouch container C.

  Then, from this state, as shown in FIG. 9D, the pair of guide members 62a and 62b are slightly moved in the direction approaching each other (the direction of arrow T). Thereby, each tip part of a pair of guide members 62a and 62b will be in the sandwiching state which clamped the upper part of the trunk of each pouch container C from the outside. As a result, in the two pouch containers C, the length in the direction of arrangement of the containers at the upper part of the body becomes smaller, and the tubular film F fitted from above becomes more difficult to be caught. Further, the pair of guide members 62a and 62b move in the direction of approaching each other to be in the delivery state, so that the cylindrical film F held in an open state around the guide members 62a and 62b is slightly loosened. As a result, the tubular film F can be easily sent out from the pair of guide members 62a and 62b by the sending member described later.

  If the distal end positions of the guide members 62a and 62b are lower than the horizontal portion 38a of the top seal portion 38 of the pouch container C, the tubular film F can be fitted without being caught on the horizontal portion 38a. The operation of sandwiching the two pouch containers C by the pair of guide members 62a and 62b may be omitted.

  As shown in FIGS. 9D and 10, the tubular film F is applied to the film fitting device 14 from the pair of guide members 62 a and 62 b of the film fitting head 60 at a position corresponding to the film fitting position α. A delivery member 72 for moving down is provided. In the present embodiment, the delivery member 72 is formed in a portal shape and has two legs that hang down in parallel. However, the delivery member 72 is not limited to the above-described portal type, and may be formed of a straight rectangular bar or plate.

  As shown in FIG. 9 (d), in a state where the tip ends of the pair of guide members 62a and 62b sandwich the upper part of the body of the two pouch containers C, as shown in FIG. It moves down in the V direction. As a result, the tips of the two legs of the delivery member 72 having the gate shape press the upper edge of the film. As a result, the tubular film F is sent out from the pair of guide members 62a and 62b, and fitted around the two pouch containers C arranged in a row. At this time, the clamp members 53 are moved in the direction of the arrow W so as to be separated from each other so as not to interfere with the tubular film F to be fitted, and the two pouch containers C are released.

  As described above, according to the film fitting apparatus 14 of the present embodiment, the body of the pouch container C is moved by pressing the body of the pouch container C with the clamp member 53 and moving the contents to the upper part of the body. The upper part is swelled, so that the body sheet materials 31, 32 can be stretched. As a result, the upper portions of the body portions of the two pouch containers C arranged adjacent to each other are hardly deformed. Therefore, in a state where the heat-shrinkable tubular film F is opened, it is possible to stably fit the periphery of the two pouch containers C to be bound from above.

  Further, since the horizontal width of the pair of guide members 62a and 62b included in the film-fitted head 60 is set to be longer than the length of the horizontal portion 38a of the top seal portion 38 of the pouch container C to be bound, The tubular film F opened by the guide members 62a and 62b can be fitted around the two pouch containers C without being caught on the horizontal portion 38a of the top seal portion 38. In this case, even if the lower end of the cylindrical film F contacts the downwardly inclined portion 38b of the top seal portion 38 of the pouch container C, the tubular film F can move downward while being guided by the inclined portion 38b. Therefore, the tubular film F to be fitted is not caught.

  When the pair of guide members 62a and 62b receive the tubular film F, they move to positions close to each other, so that the tubular film can be reliably received around the outside thereof. Until the pair of guide members 62a and 62b receiving the cylindrical film F move from the film receiving position β to the film fitting position α by the rotation of the disc-shaped base 59, the cylindrical film F is opened without loosening. The pair of guide members 62a and 62b have been moved to positions separated from each other so as to be maintained in the state of being separated. Thereby, it is possible to prevent the cylindrical film F from shifting in the circumferential direction around the pair of guide members 62a and 62b. In addition, in the present embodiment, since the tubular film F is pressed against the guide member 62a by the clip 68, the circumferential displacement of the tubular film F can be more reliably prevented.

  Further, in the present embodiment, the pair of guide members 62a and 62b move in the direction approaching each other when the film is fitted, and the upper part of the body of the two pouch containers C is arranged at each lower end in the direction in which the containers are arranged. By being pinched, the thickness of the two pouch containers C in the direction in which the containers are arranged decreases. Thereby, when the opened tubular film F is fitted, it is hard to be caught by the top seal portion 38 of the pouch container C, and the film fitting operation can be performed stably. In addition, since the lower ends of the pair of guide members 62a and 62b come into contact with the upper portions of the body portions of the two pouch containers C arranged on both sides in the direction in which the containers are arranged, the cylinders sent out from the guide members 62a and 62b. The film F can be transferred to the pouch container C without fail. As a result, the film fitting operation can be performed more stably.

  Further, the film fitting apparatus 14 of the present embodiment employs a so-called index system in which the cylindrical film F is fitted while rotating the disk-shaped base 59 and rotating the four film fitting heads 60. This makes it possible to prevent the rotating belt, the roller and the like from coming into contact with the outer peripheral surface of the tubular film F to be fitted. Can be fitted.

  FIG. 11 shows that two pouch containers C each having a tubular film F fitted thereon pass through the heating device 18 to produce a pouch container bundle B, and a sealing member is attached to the pouch container bundle B. It is a perspective view which shows a mode that it is performed.

  As shown in FIG. 11, the two pouch containers C in which the cylindrical film F has been fitted by the film fitting device 14 as described above are supplied from the second conveyor 24 to the third conveyor 26, It is subsequently conveyed by the three conveyors 26 and passes through the heating device 18. The heating device 18 has a tunnel shape and has an atmosphere composed of high-temperature air or steam. Therefore, the tubular film F thermally shrinks when passing through the heating device 18, and as a result, the two pouch containers C are united by the tubular film F to produce the pouch container bundle B.

  Thereafter, the pouch container bundle B is continuously conveyed by the third conveyor 26 and passes through the seal sticking device 20. As shown in FIGS. 1 and 11, the seal attaching device 20 includes a pair of container holding belts 80 extending on both sides of the second conveyor 24 along the container transport direction. Each of the pair of container holding belts 80 is constituted by an endless belt rotating in the direction of the arrow, and is driven to rotate at a speed synchronized with the second conveyor 24. The interval between the pair of container holding belts 80 is set to be smaller than the thickness of the pouch container bundle B in the direction in which the containers are arranged. Therefore, when the pouch container bundle B is conveyed while being pinched by the pair of container pinching belts 80, the lower part of the body of each pouch container C in the height direction is pressed. As a result, the upper part of the body of the pouch container C is in a stretched state, and the sealing member described below can be securely attached.

  Also, in the seal sticking device 20, as shown in FIGS. 1 and 11, a long strip-shaped release paper 88 in which a seal member 86 is stuck and held at a predetermined interval is fed out from the control reel 82, and is not shown. After making a U-turn at the edge of the peeling plate, it is wound on a take-up reel 84. When the release paper 88 makes a U-turn, the seal member 86 is peeled off from the release paper 88, and is adhered across the body sheets 31, 32 and the tubular film F of each of the pouch containers C constituting the pouch container binding body B. Is done. Thereby, in the pouch container binding body B, it is possible to reliably prevent the two pouch containers C from falling out of the tubular film F after the heat shrinkage.

  The pouch container bundle B to which the seal member 86 has been attached in this manner is continuously transported by the third conveyor 26 and supplied onto the work table 28 as shown in FIG. Then, the pouch container bundle B is packed in a box by the worker O.

  As described above, according to the pouch container binding body manufacturing system 10 including the film fitting device 14 of the present embodiment, the pouch container binding body B united by the heat-shrinkable tubular film F is continuously formed. It can be manufactured stably.

  In this embodiment, the pouch container C is prevented from falling out of the tubular film F by sticking the seal member 86, but the present invention is not limited to this. For example, a heat-sensitive adhesive layer is formed on the inner peripheral surface of the cylindrical film F, and the heat-sensitive adhesive activated by heating when passing through the heating device 18 causes the cylindrical film F itself to form the pouch container C. It may be stuck on the trunk sheet. In this case, the seal sticking device 20 can be omitted, and the system configuration can be simplified and the cost can be reduced.

  Next, referring to FIG. 12, another embodiment of the film-fitted head 60A is shown. FIGS. 12A to 12F show a stepwise manner in which the tubular film F is fitted to the two pouch containers C arranged at the film fitting position α. In the following, the same components as those of the film-fitted head 60 described above are denoted by the same reference numerals, and description thereof will be omitted.

  The film-fitting head 60A is a tilting guide-type fitting head fixedly arranged at a fixed position with respect to the film-fitting position α. The film-fitted head 60A includes an inclined shaping member 90 having two inclined guide portions 91 extending downward in a V-shape. The lower ends of the two inclined guide portions 91 are connected to the upper ends of the pair of guide members 62a and 62b, respectively. An endless transport belt 92 is provided in contact with each of the inclined guide portions 91. Further, the lower portions of the outer surfaces of the pair of guide members 62a, 62b are provided with rotationally driven delivery rollers 94a. 94b are arranged in contact with each other. Note that a roller may be used instead of the transport belt 92, and a belt may be used instead of the delivery rollers 94a and 94b.

  In the film-fitted head 60A configured as described above, a cylindrical film F having a substantially boat-shaped opening is supplied to the upper end of the inclined shaping member 90 as shown in FIG. Then, the transport belt 92 rotates while moving in contact with the outer peripheral surface of the tubular film F, whereby the tubular film F is transported downward along the two inclined guide portions 91. In this transporting process, the cylindrical film F is moved as shown in FIG. As shown in (c), it is shaped into a substantially rectangular parallelepiped shape and delivered to the pair of guide members 62a and 62b.

  The cylindrical film F delivered to the pair of guide members 62a and 62b in an open state is sent downward by the delivery rollers 94a and 94b as shown in FIG. 12D, and is sent between the pair of guide members 62a and 62b. It is fitted around two pouch containers C located in a row. At this time, as described above, the clamp member 53 releases the clamp of the pouch container C so as not to interfere with the tubular film F.

  Then, as shown in FIG. 12 (e), the clamp member 53 returns to the state in which the two pouch containers C are clamped, and as shown in FIG. 12 (f), the pouch container C is unloaded from the film-fitted head 60A by the second conveyor 24. Is done.

  According to the film-fitting device including the above-described film-fitting head 60A, since the film-fitting head 60A including the pair of guide members 62a and 62b is fixedly arranged at the film-fitting position α, a plurality of films is formed. This eliminates the need for a configuration for rotating and moving the disk-shaped base on which the fitted head is mounted, and can simplify the apparatus configuration and reduce the cost.

  Note that the present invention is not limited to the configurations of the above-described embodiments and modified examples, and various changes and improvements can be made in the matters described in the claims of the present application and equivalent scope thereof.

  In the above, the case where the pouch container C in which the plug 42 is attached to the top sheet 34 is bound by the tubular film F to manufacture the pouch container bundle B has been described, but the form of the pouch container C is not limited to this. It is not limited. For example, as shown in FIG. 13A, the pouch container C2 includes a pair of body sheets 31, 32 and a bottom sheet 33, does not have a top sheet, and has upper ends of the pair of body sheets. A soft packaging material in which a stopper 42 is attached to a horizontal portion 38a of a top seal portion 38, which is a joint portion between the edges, may be used.

  Alternatively, as shown in FIG. 13B, the pouch container C3 includes a pair of body sheets 31, 32 and a bottom sheet 33, does not have a top sheet and a spout, and has a pair of body parts. A soft packaging material of a type in which contents are taken out by cutting off the upper joint corners of the sheets 31 and 32 may be used. Furthermore, as shown in FIG. 14, the pouch container C4 is formed by joining a pair of front and back torso sheets 31, 32, a pair of left and right side gusset sheets 30a, 30b, and upper edges of the torso sheets 31, 32. It may be a side gusset pouch having a spout 42 attached to a top seal portion 38 which is a portion. In these cases, the top seal portion 38 may have a shape including only a horizontal portion and not having an inclined portion, and the width of the pair of guide members of the film-embedded head in the horizontal direction may be changed to the top seal of the pouch containers C3 and C4. What is necessary is just to set larger than the horizontal length of the whole part 38. Then, two cylindrical films opened by the pair of guide members can be lined up and fitted around the pouch containers C3 and C4 without being caught on the horizontal portion of the top seal portion of the pouch container.

  Further, in the above description, the case where the two pouch containers C are united by the tubular film F has been described, but the number of the pouch containers C bound by the tubular film F may be three or more.
