Description

  The present invention relates to a vertical multi-row automatic filling and packaging machine for manufacturing a package by filling a packaging bag of a packaging film with contents such as liquid, and more particularly to a guide mechanism for guiding an R-cut packaging bag.

  Conventionally, stick-type packaging bags have been manufactured by a vertical multi-row automatic filling and packaging machine. The vertical multi-row automatic filling and packaging machine cuts the raw film packaging film with a slitter for each required size in each packaging bag, and forms the cut packaging film into a bag shape. A vertical seal is applied to the formed overlapping portion of both ends, and a horizontal seal is applied by sandwiching a specified position of the packaging film that is formed into a cylindrical shape by the vertical seal.

  When filling the stick-type packaging bag with the liquid material, the vertical multi-row automatic filling and packaging machine feeds the liquid material into the completed bag-shaped packaging film using a filling nozzle. Thereafter, in the vertical multi-row automatic filling and packaging machine, the raw material injection port is horizontally sealed and sealed, and the vicinity of the center of the sealed horizontal seal portion is separated using a cutter device to form individual packaging bags. An example of such a vertical multi-row automatic filling and packaging machine is disclosed in Patent Document 1.

  In such a separated individual packaging bag as described above, an accident in which the corners of the cut portion and the completed bag portion come into contact with each other to form a hole is likely to occur. Therefore, it is constructed in a shape (so-called “R-cut” shape) in which the corner of the cut part that is laterally sealed is cut off to prevent such an accident.

  In the cutter device that cuts into the R-cut shape, unlike the case of the straight cut, a punching structure is required to cut off the corner portion. Then, in order to surely punch out including the corner portion by one punching operation, the central portion is punched with a width so that the corner portions of both corners are connected. For this reason, the probability of opening a hole in the packaging bag when the shift of the cut position occurs is higher than that of a normal straight cut, and it is required to minimize the position shift.

Further, if burrs are generated at the cut end of the packaging bag when punching into the R-cut shape, the cut individual packaging bag is caught by the punching die. In order to minimize the burrs generated when punching into the R-cut shape, there is a need for a device that absorbs the slack of the continuous packaging bags as much as possible.
Japanese Patent Laid-Open No. 9-272511

As described above, in the conventional vertical multi-row automatic filling and packaging machine, when the packaging bag is cut into the R-cut shape, it is necessary to surely punch it in a state of crossing the horizontal seal portion. Therefore, there is a problem that high positioning accuracy of the packaging bag is required, and a stick-shaped packaging bag filled with the liquid raw material cannot be manufactured efficiently and reliably.
The present invention has been made to solve such problems, and an object thereof is to provide a vertical multi-row automatic filling and packaging machine capable of smoothly producing a packaging bag filled with a liquid raw material. To do.

The vertical multi-row automatic filling and packaging machine according to the present invention is a slitter device that slits a wide sheet film into a plurality of packaging films, and synchronously pulls out each of the plurality of packaging films by one packaging bag. A vertical seal device and a horizontal seal device for vertically sealing and laterally sealing, a filling device for filling each sealing film with a liquid raw material, and a plurality of packaging bags filled with the liquid raw material with the horizontal sealing portion A vertical multi-row automatic filling and packaging machine provided with a cutter device that cuts and wraps each packaging bag, the cutter device R-cutting the transverse seal portion by die cutting, It has a guide mechanism that abuts on the packaging bag and guides the packaging bag to the R-cut mechanism.
In such a configuration, since the packaging bag can be introduced into the R-cut mechanism while being guided, the positioning accuracy of the packaging bag can be improved. Therefore, since the cut portion of the lateral seal portion can be surely punched out, the packaging bag filled with the liquid raw material can be manufactured smoothly.

Further, the guide mechanism has a bag guide that abuts the packaging bag from the left and right to define a position of the packaging bag in a lateral direction, and a feed roller that abuts the packaging bag and feeds the packaging bag.
Preferably, the bag guide has a substantially U-shaped cross section, defines a left-right position of the packaging bag, and supports the packaging bag from a direction facing the feed roller.
Thereby, a bag guide can support the press by a feed roller from back while supporting a packaging bag from the left-right direction. Therefore, the feed roller can optimally press the packaging bag with the roller pressure set as appropriate.

Further, the feed roller rotates at a rotation speed faster than the transfer speed of the packaging bag so as to pull the packaging bag from above to below.
Thereby, since the packaging bag can be sent while being pulled in the vertical direction, it is possible to absorb the slack in the vertical direction of the packaging bag. Therefore, even if burrs are generated at the cut end of the packaging bag, the packaging film can be fed by the feed roller, so that the packaging film can be prevented from being caught. Therefore, a packaging bag filled with the liquid raw material can be manufactured satisfactorily.

In addition, in this specification, R cut shows the cutting | disconnection for removing the corner of a sharp packaging bag. Therefore, the R-cut in this specification includes not only the case where the corners of the packaging bag are removed in a substantially curved shape, but also the case where the corners of the packaging bag are removed to such an extent that the packaging bags are not damaged.
In addition, the substantially drum-shaped punching die in the present specification includes not only a drum having a width at the center but also a drum having no width. Therefore, the substantially drum-shaped punching die in this specification includes a case where only the corners of the packaging film are punched and the corners are simply cut.

  ADVANTAGE OF THE INVENTION According to this invention, the vertical multi-row automatic filling packaging machine which can manufacture smoothly the packaging bag with which the liquid raw material was filled can be provided.

In FIG. 1, the vertical multi-row automatic filling and packaging machine according to the present invention is generally indicated by reference numeral 1, and FIG. 1 is a view observed from the front side (front) to the back side (rear). . Hereinafter, the vertical multi-row automatic filling and packaging machine 1 is abbreviated as the automatic packaging machine 1.
As shown in FIG. 1, the automatic packaging machine 1 includes a forming device 2, a vertical sealing device 3, a horizontal sealing device 4, a raw material supply device 5, a filling device 6, a cutter device 7, and an operation panel box 8.

  The forming device 2 is a device that forms a packaging film into a substantially cylindrical shape, and includes a former pipe 21, a former ring 22, and a bag making guide roller 23. The former pipes 21 are arranged in multiple rows. The former ring 22 is provided for each former pipe 21, and the former pipe 151 is inserted through the former ring 22. A bag making guide roller 23 is also provided for each former pipe 21.

The vertical sealing device 3 is a device that is provided below the holder 24 and performs vertical sealing on the packaging film formed in a substantially cylindrical shape on the former pipe 21. The horizontal sealing device 4 is a device that is provided below the vertical sealing device 17 and laterally seals the vertically sealed packaging film.
The raw material supply device 5 is a device that supplies a liquid raw material to a packaging bag formed by a horizontal seal, and includes a hopper 51 and a pump device 52. The hopper 51 is a storage container that stores a liquid raw material. The pump device 52 is a device that sucks the liquid raw material and sends it to the hopper 51.

The filling device 6 is a device that fills the packaging bag with the liquid raw material supplied from the hopper 51, and includes a filling nozzle 61 and a filling nozzle vertical mechanism 62. The filling nozzle 61 is a member that distributes and supplies the liquid raw material supplied from the hopper 51 into each former pipe 21. The filling nozzle up / down mechanism 62 is a mechanism for moving the filling nozzle 61 up and down so that the filling nozzle 61 does not touch the liquid surface as the liquid material is filled.
The cutter device 7 is a device that cuts a packaging bag filled with a liquid raw material between two horizontal seals at the position of the horizontal seal and divides it into sticky packaging bags. The cutter apparatus 7 in the automatic packaging machine 1 which concerns on this invention removes the corner | angular part of a packaging bag by carrying out R cut.
The operation panel box 8 incorporates a device for operating each drive device of the automatic packaging machine 1 and is attached to a main body frame 81 that supports various drive devices of the automatic packaging machine 1. Further, the main body frame 81 is provided with a display / alarm lamp 82 which is a notification means for indicating the operation state of the automatic packaging machine 1.

Then, operation | movement of the automatic packaging machine 1 which concerns on this invention is demonstrated roughly using FIG.
A side view of FIG. 2 shows an example of the configuration of the automatic packaging machine 1 according to the present invention. FIG. 2 is a view observed from the right to the left in FIG. As shown in FIG. 2, the automatic packaging machine 1 includes a slitter device 9 in addition to the above devices.
The packaging film 111 drawn from the original film 110 is cut into multiple rows by the slitter device 9. The packaging film 111 divided into the multiple rows is formed into a substantially U shape by each bag making guide roller 23. The packaging film 111 is wound around the former pipe 21 in this formed state, and is inserted between the former pipe 21 and the former ring 22. The former ring 22 overlaps both ends of the packaging film 111 in a palm shape, and the packaging film 111 is formed into a substantially cylindrical shape. The packaging film 111 is introduced into the vertical sealing device 3 in this state, and the overlapped portion is vertically sealed.

  The packaging film 111 that has become substantially cylindrical by this vertical seal is introduced into the horizontal seal device 4 and is subjected to a horizontal seal in the short direction. This horizontal seal becomes the bottom part of the packaging bag 112 and the liquid raw material is injected from the filling nozzle 61 inserted into the former pipe 21. At this time, the filling nozzle 61 injects the liquid raw material while the filling nozzle up-and-down mechanism 62 moves the filling nozzle 61 upward in accordance with the injection amount of the liquid raw material. When a predetermined amount of liquid raw material is injected, the horizontal sealing device 4 pulls the packaging film 111 downward by an intermittent motion.

  The packaging film 111 is pulled out from the original fabric roll 110 by this intermittent motion. After the backward movement, the lateral sealing device 4 performs lateral sealing again with the packaging film 111 stopped. Thereby, the packaging bag 112 is completed and introduced into the cutter device 7. The cutter device 7 individually seals the packaging bags 112 connected in series by cutting the lateral seal portion. At this time, as will be described later, the cutter device 7 performs R-cut to process the corners of the packaging bag 112 into a curved shape.

Next, the cutter device 7 of the automatic packaging machine 1 will be described in detail with reference to FIGS. 3 to 7. The cutter device 7 according to the present invention removes the corners of the packaging bag 112 by R-cut.

The R-cut mechanism 71 is a mechanism for punching a horizontal seal in a substantially drum shape. The R cut mechanism 71 includes a punching die 711, a pressing die 712, and an air cylinder 713. An example of a partial configuration of the R cut mechanism 71 is shown in FIG. 4A is a front view of the punching die 711, FIG. 4B is a top view of the pressing die 712, FIG. 4C is a rear view of the pressing die 712, and FIG. FIG.
The punching die 711 is a member in which a plurality of through holes are formed in a substantially flat plate member. Specifically, the through-hole can be a substantially drum-shaped hole 714. The punching die 711 is arranged so that the punching holes 714 are arranged substantially horizontally. Specifically, the punching die 711 is disposed so that the longitudinal direction of the substantially drum-shaped punching hole 714 is substantially horizontal. Further, the width of the punch hole 714 is larger than the width of the horizontal seal portion in order to R-cut the horizontal seal portion in the width direction.

The push die 712 is a member having a shape corresponding to the shape of the punch die 711 and punching by pressing the lateral seal against the punch die 711. The pressing die 712 has a shape such that the tip of the pressing die 712 fits into the punching die 711, and the tip shape has a substantially drum-shaped cross section. A plurality of pressing dies 712 are arranged in accordance with the arrangement state of the cutting dies 711. Specifically, the plurality of punching dies 711 are arranged substantially horizontally, and specifically, are arranged so that the longitudinal ends of the tips having a substantially drum-shaped cross section are substantially horizontal.
The air cylinder 713 is traction means for pushing out and pulling back the pressing die 712. A plurality of the air cylinders 713 are arranged and fixed to each of the plurality of pressing dies 712.

The guide mechanism 72 is a mechanism for guiding the packaging bag 112 in the cutter device 7 in a substantially horizontal direction. The guide mechanism 72 includes a bag guide 721, a feed roller 722, and a motor 723. An example of a partial configuration of the guide mechanism 72 is shown in FIG. FIG. 5A is a front view, and FIG. 5B is a top view.
The bag guide 721 is a member bent into a substantially U-shaped cross section. The bag guide 721 is attached above the R-cut mechanism 71. Specifically, the bag guide 721 is disposed substantially vertically along the transfer path of the packaging film 111. A plurality of bag guides 721 are provided for each packaging bag 112, and these bag guides 721 send each packaging bag 112 to the R-cut mechanism 71 in a state of being in contact with the side of each packaging bag 112.

The feed roller 722 is a roller member that contacts the surface of the packaging bag 112. A plurality of feed rollers 722 are provided, and these feed rollers 722 are in contact with each packaging bag 112. Further, even if the feeding roller 722 abuts the packaging bag 112 more strongly, the bag guide 721 having a substantially U-shaped cross section can support the pressing by the feeding roller 722 from behind.
The motor 723 is a rotation driving unit. The motor 723 supports the plurality of rollers 722 by the same rotation shaft 724 and rotates the plurality of feed rollers 722 in the same direction.

The peeling mechanism 73 is a mechanism for peeling the packaging bag 112 attached to the punching die 711 of the R-cut mechanism 71 from the punching die 711. The peeling mechanism 73 includes a peeling plate 731 and an air cylinder 732. An example of a partial configuration of the peeling mechanism 73 is shown in FIG. FIG. 6A is a front view, and FIG. 6B is a top view.
The peeling plate 731 is a substantially plate-like member, and a plurality of peeling plates 731 are provided for each punch hole 714. These peeling plates 731 are attached to an attachment member 733. The peeling plate 731 is disposed behind the punching die 711 and is disposed between the plurality of punching die 711 and the pressing die 712.

Specifically, the peeling plate 731 is disposed between the packaging bag 112 and the punching die 711. More specifically, the peeling plate 731 is disposed around each punch hole 714 of the punch die 711, and is punched between the punch hole 714 and the packaging bag 112 when punched by the punch die 711 and the push die 712. It is pinched.
The air cylinder 732 is traction means that pushes the pull-out plate 731 and pulls it back. The air cylinder 732 is fixed to the mounting member 733 in order to push and pull the plurality of peeling plates 731 simultaneously.

The dust collection mechanism 74 is a mechanism that collects chips generated by the R cut. The dust collection mechanism 74 includes an absorption pipe 741, a suction device 742, and a scrap collection pipe 743. An example of a partial configuration of the dust collecting mechanism 74 is shown in FIG. FIG. 7A is a top view and FIG. 7B is a front view.
The absorption pipe 741 is a substantially cylindrical pipe. A plurality of absorption pipes 741 are provided for each punch hole 714 of the punch die 711. Specifically, these absorption pipes 741 are arranged rearward with respect to the punching die 711. Specifically, these absorption pipes 741 are assigned to the respective punched holes 714 on the back surface of the punching die 711. At this time, each absorption pipe 741 may contact the periphery of the punch hole 714 or may be separated from the punch die 711.

The suction device 742 is a suction unit.
The scrap collecting pipe 743 is a substantially cylindrical pipe. The scrap collecting pipe 743 is disposed on the back surface of the punching die 711 and is connected to the plurality of absorption pipes 741. At the same time, the scrap collecting pipe 743 is attached to the suction device 742.

Then, operation | movement of the cutter apparatus 7 which has such a structure is demonstrated in detail.
The packaging bag 112 filled with the liquid material is guided from the left and right by the bag guide 721 of the guide mechanism 72. Specifically, the bag guide 721 defines an allowable range in which the packaging bag 112 can be moved in the left-right direction by coming into contact with the packaging bag 112 from the left-right direction when the packaging bag 112 moves in the left-right direction.

The feed roller 722 of the guide mechanism 72 contacts the surface of the packaging bag 112 in a direction from the front to the rear. The feed roller 722 feeds the packaging bag 112 downward while rotating in the abutted state. At this time, the packaging bag 112 is supported from the rear to the front by a bag guide 721 having a substantially U-shaped cross section. The packaging bag 112 introduced into the R-cut mechanism 71 temporarily stops in a state where the lower horizontal seal is disposed between the punching die 711 and the pressing die 712.
Further, the rotational speed of the feed roller 722 may be a speed that can feed the packaging bag 112 downward. For example, the feed roller 722 can be set to a speed that is slightly higher than the transfer speed of the packaging bag 112.

  When the push die 712 is pushed from the front toward the rear, the push die 712 fits into the fixed punch die 711. Then, the horizontal seal of the packaging bag 112 is cut out, and a plurality of packaging bags 112 connected to each other are individually separated. At this time, since the shape of the punching die 711 and the pressing die 712 has a substantially drum shape, the corners of the packaging bag 112 are cut out in a curved shape, and the packaging bag 112 without corners is formed.

When the lateral seal portion of the packaging bag 112 is cut out in a substantially drum shape, the peeling plate 731 of the peeling mechanism 73 is pushed forward in the packaging bag 112. The peeling plate 731 pushes the packaging bag 112 forward by this extrusion and peels it from the punching die 711.
The cut-out horizontal seal portion is pushed out to the back surface of the punching die 711 through the punching hole 714 penetrating the punching die 711. At this time, the suction device 742 of the dust collection mechanism 74 performs suction. Therefore, the chips pushed out to the back of the punching die 711 are sucked into the suction device 742 and collected through the absorption pipe 741 and the scrap collecting pipe 743.

  The conventional cutter device cuts the horizontal seal portion substantially horizontally and linearly. Therefore, the conventional bag guide can be surely separated into the individual packaging bags 112 by crossing the lateral seal portion even if the packaging film 111 sways left and right. When the conventional bag guide gets too close to the packaging bag 112, the packaging bag 112 comes into contact with the bag guide and gets caught. In particular, in a vertical multi-row automatic packaging machine, a large number of packaging bags 112 are manufactured at a high speed, so that the large number of packaging bags 112 are lost due to the catch. Therefore, the conventional bag guide has a width compared to the width of the packaging bag 112 and is not provided near the packaging bag 112.

  On the other hand, the cutter device 7 in the present invention performs R-cutting by punching out the lateral seal portion. Therefore, when the packaging bag 112 moves to the left and right, the R-cut mechanism 71 cannot punch out the lateral seal portion by the R-cut or cannot perform the R-cut symmetrically. Therefore, the bag guide 731 has a width close to the width of the packaging bag 112, and it is necessary to guide the packaging bag 112 close to define the left and right positioning with certainty.

  Thus, the bag guide 721 is disposed closer to the packaging bag 112 than the conventional bag guide. Therefore, the possibility that the packaging bag 112 comes into contact with the bag guide 721 and is caught increases. In particular, in the case of the automatic packaging machine 1 that manufactures a large number of packaging bags 112 at a high speed in a vertical multi-row as described above, this catching becomes a big problem. Therefore, the feed roller 722 contacts the packaging bag 112 and feeds the packaging film 111 in the transport direction so that the movement of the packaging film 111 is not hindered by this catch. Therefore, both the bag guide 721 and the feed roller 722 can surely prevent the packaging film 111 from shifting from side to side and also reliably prevent the packaging bag 112 from being caught.

  As described above, in the automatic packaging machine 1 according to the present invention, the packaging bag 112 can be positioned by the guide mechanism 72 of the cutter device 7. Specifically, since the bag guide 721 of the guide mechanism 72 contacts the packaging bag 112 from the left-right direction, the position of the packaging bag 112 in the left-right direction can be defined reliably. At the same time, the feed roller 722 of the guide mechanism 72 abuts the surface of the packaging bag 112 while feeding the packaging bag 112 in the transfer direction, so that the slack in the vertical direction of the packaging bag 112 can be absorbed. As a result, the positioning accuracy of the packaging bag can be improved, and an R-cut can be applied to the correct position of the lateral seal. Therefore, the stick-shaped packaging bag 112 filled with the liquid raw material can be manufactured smoothly.

  Further, the vertical slack of the packaging bag 112 can be absorbed by the feed roller 722 of the guide mechanism 72. Therefore, even if a burr generated when the R-cut mechanism 71 is punched into an R-cut shape, the vertical position error can be reduced and the hooked packaging film 111 can be forcibly sent. Therefore, an accident caught on the die 711 can be prevented, and the finish of the individual packaging bag 112 can be kept good.

  Furthermore, the feed roller 722 of the guide mechanism 72 rotates at a rotational speed faster than the conveying speed of the continuous packaging bag 112 and pulls the packaging bag 112 downward. Thereby, the slack absorbing power of the packaging bag 112 can be increased, and at the same time, the packaging bag 112 can be peeled off even when it is attached to the punching die 711.

  The bag guide 721 has a substantially U-shaped cross section, but the present invention is not limited to this, and the packaging bag 112 may be guided from the left and right. For example, the shape of the bag guide 721 is not limited to a substantially U-shaped cross section as described above. For example, the bag guide 721 has a substantially cylindrical shape that opens only the contact surface with the feed roller 722 and surrounds the packaging bag 112. Also good.
