DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for manufacturing a packaging container for forming a package, for example, a liquid such as drinking water and a drink, and a powdery or granular food. The present invention relates to a method and an apparatus for manufacturing a packaging container provided for a package containing liquid food and drink.

[0002]

2. Description of the Related Art Conventionally, a sealed bag has been provided as a package for containing a beverage. The bag is formed by polymerizing a pair of films laminated with aluminum foil, welding the periphery, filling the beverage from the opening of the bag, and sealing the opening by welding or the like. Therefore, when a user drinks a beverage, a part of the bag is torn, a straw is inserted into the bag, and the bag is sucked.

[0003] Such a bag is relatively flat as a whole and has a problem that not only the capacity is small but also it is not possible to display the bag in an upright installed state at the time of over-the-counter sales.

[0004] For this reason, in recent years, expandable and contractible bags having a gusset formed from the bottom to the side edge have been provided, and have been well received as a beverage package. This is because such a scalable bag, when filled with beverages, has a large capacity because the gusset expands and forms a three-dimensional form, and can be displayed in a state where the bag is standing upright at the time of over-the-counter sales.

[0005]

In the above-described expandable and contractible bag, the bag material is formed of a relatively thick film in order to maintain shape. In particular, because it is necessary to form a thick aluminum foil laminated on the film, resource saving,
It is not preferable in terms of garbage pollution.

Further, since a thick bag material having excellent shape retention is used, it is not always easy to form a gusset at the time of bag making, and a large-sized bag making facility is required.

On the other hand, the bag body is expanded so as to form a three-dimensional form by filling a beverage from the flat state in which the gusset is folded, but since the gusset is also formed at the bottom, the bottom is desired. It is hard to be flat. For this reason, it is possible to place the three-dimensional bag upright on the display stand during over-the-counter sales, etc., but it is difficult to maintain an upright posture, and there is a problem that it becomes inclined and easily falls. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings.

As shown in FIG. 1A, a packaging container 1 of the present invention is formed by erecting a cylindrical wall 4 made of a film from a peripheral wall 3b of a dish-shaped bottom member 2. The food and drink package 5 as described above is formed on the basis of the above.

That is, as shown by a chain line in FIG. 1A, a pair of gussets 6, 6 are formed by folding both sides of the cylindrical wall 4 inward, and then the butted opening edges 7, 7 are formed. A three-dimensional package 5 is provided by welding 8 including the gussets 6 and 6 in a horizontal straight line.

In the first example of the package shown in FIG. 1 (B), after the packaging container 1 is filled with food or drink such as a beverage, the opening edges 7, 7 include the gussets 6, 6, as described above. By welding 8 in a horizontal and straight line, the package 5 in a three-dimensional form is provided, and the package 5 is commercially available with a straw 10 attached to the package 5 via an adhesive seal piece 9. Therefore, when the user drinks the beverage, the notch 11 formed in the welding portion 8 in advance is torn, and the straw 10 is inserted into the inside of the package 5 and sucked.

In the second example of the package shown in FIG. 1 (C), a linear chuck means 12 comprising male and female means which can be detachably attached is attached to the center of the opening edges 7, 7 by welding or the like. Opening edges 7, 7 on both sides of the chuck means 12 are welded 8a, 8a including the gussets 6, 6, respectively. Accordingly, after the package 5 is filled with food or drink such as a beverage in a state where the chucking means 12 is opened, the chucking means 12 is sealed, and if necessary, a welding seal parallel to the chucking means 12 is applied. To be served. Therefore, when the user drinks the beverage, the welding seal may be cut off and the chuck means 12 may be opened. At this time, it is preferable to attach a straw as in the first example.

In the third example of the package shown in FIG. 1 (D), when the opening edges 7, 7 are welded 8 in a horizontal straight line including the gussets 6, 6, the welding is carried out with the nozzle means 13 held therebetween. In the meantime, a cap 14 capable of opening and closing the nozzle means 13
It is more sealed. Therefore, when the user drinks the beverage, the cap 14 is removed and the nozzle means 13 is removed.
What is necessary is just to suck a drink through.

In any of the above cases, the packaging container 1 or the packaging body 5 has the cylindrical wall 4 made of a flexible film, so that when the food and drink are not filled, the cylindrical wall 4 and the bottom member 2 are flatly overlapped. While it can be stored and transported in a non-bulky state, when it is filled with food and drink in a state in which the cylindrical wall 4 is raised from the bottom member 2, it becomes a three-dimensional form and has a large capacity.
Since the bottom wall 3a is formed flat, it can be placed on a display stand or the like in an upright posture.

Next, a method and an apparatus for manufacturing the packaging container 1 shown in FIG. 1A will be described.

FIG. 2A shows a table-like transfer body 15, which is intermittently rotated around a central rotation shaft 16 by a driving device (not shown). . A plurality of columnar cores 17, in the illustrated example, six columnar cores 1 are arranged at equal intervals in the circumferential direction on the front surface of the transfer body 15.
7 are arranged in a row to constitute six stages A to F for performing each step of the bag making operation at each core position. Therefore,
The transfer body 15 has a distance corresponding to the interval between the stages (in the case of a six-stage stage as shown in the figure, 60 degrees in the circumferential direction).
Each stage is intermittently rotated, and stops while each stage is being performed in each stage. For this reason, each columnar core 1
7 starts from the first stage A, and after the subsequent stages, is made to go around endlessly so as to return to the original first stage A. The transfer body 15 may be constituted by a conveyor such as a belt or a chain for intermittently moving the columnar core 17 in the endless orbital direction, in addition to constituting such a table.

As shown in FIG. 2B, the columnar core 17
Is formed in a tapered column shape whose outer diameter gradually increases from the protruding distal end toward the base portion, and includes a rotating shaft 18 rotatably mounted around the axis with respect to the transfer body 15.

Therefore, in the first stage A, the dish-shaped bottom member 2 is mounted on the tip of the cylindrical core 17 in a crowned manner (setting step). The dish-shaped bottom member 2 is not particularly limited as long as it has a heat-sealing property, but a laminated sheet of paper and a synthetic resin film, a laminated sheet of a metal film and a synthetic resin film, and a synthetic paper and a synthetic resin film. A dish-shaped bottom member 2 having a bottom wall 3a and a peripheral wall 3b can be formed by hot pressing or cold pressing a sheet selected from a laminate sheet and other laminate sheets. As for the synthetic resin film to be laminated, polypropylene, polyethylene and the like are excellent from the viewpoint of heat welding property, and nylon and polyester are excellent from the point of gas barrier property. In the case of lamination using a metal film, the metal film may be formed by aluminum evaporation other than aluminum foil, and may be formed by laminating an inorganic film by silica evaporation or the like on a synthetic resin film. Further, the dish-shaped bottom member 2 is formed by press-molding a sheet, or by injection molding or the like.
It may be an integrally molded product of a synthetic resin provided with.

Although not shown, the bottom member 2 is supplied toward the first stage A during the setting step.
For example, a number of bottom members 2 are sequentially supplied by conveyor means such as a belt or a chain. Alternatively, a stacked body in which many bottom members 2 are stacked with the bottom wall 3a facing upward or downward is waiting at a position near the first stage A. Then, one end of the bottom member 2 is pinched by a supply means such as a robot finger or a suction finger, and the columnar core 1
7 is covered with the tip. At this time, the columnar core 1
As shown in FIG. 2 (B), an air hole 1
9 is provided, and the air suction / discharge means 20 connected from the inside of the core 17 via the rotary shaft 18 is connected.
It is preferable that air is sucked from the air hole 19 through the air hole 19 and the covered bottom member 2 is fixed so as not to fall off from the tip of the columnar core 17. A setting means for attaching the bottom member 2 to the tip of the columnar core 17 in a crowned manner.

The columnar core 17 on which the bottom member 2 is set is:
By rotating the transfer body 15 intermittently, it is transferred from the first stage A to the second stage B and stopped. Therefore, as shown in FIG. 3, the strip-shaped film 21 continuous from the direction intersecting the axis of the columnar core 17 toward the core.
Is delivered. That is, although not shown, a film feeding means for intermittently feeding the long belt-shaped film 21 from a winding roll of the film via a step roller or the like by a driving roller is configured. Then, a portion 21 a near the feeding end of the strip film 21 is in contact with the peripheral surface of the columnar core 17. At this time, a fixing means 22 composed of an air hole connected to the air suction / discharge means 20 is provided on the peripheral surface of the columnar core 17, and a portion 21a near the feeding end is provided.
Is absorbed and fixed.

The belt-like film 21 is not particularly limited as long as it has a heat-welding property, but may be a laminate film of paper and a synthetic resin film, a laminate film of a metal film and a synthetic resin film, or a synthetic film of a synthetic paper and synthetic resin film. It can be selected from laminated films and other laminated films. The synthetic resin film to be laminated, from the viewpoint of heat welding, polypropylene, polyethylene and the like are excellent, from the viewpoint of gas barrier properties,
Nylon, polyester, etc. are excellent. In the case of lamination using a metal film, the metal film may be formed by aluminum evaporation other than aluminum foil, and may be formed by laminating an inorganic film by silica evaporation or the like on a synthetic resin film. The thickness T1 of the film 21 is equal to the thickness T of the bottom member 2.
2, it is preferable that T1 <T2.
It may be ≦ T2. Also, as shown in FIG. 1, since it constitutes the cylindrical wall 4 of the packaging body 5, various printing displays such as product display are formed on the laminate film by gravure printing, flexographic printing, or other printing means. Has been given.

Preferably, a guide roller 23 which is freely rotatable along the peripheral side of the columnar core 17 is disposed via a frame 24 so as to be able to advance and retreat by reciprocating drive means 25 such as a cylinder device. A guide member 25 extending along 23 is provided. Therefore, the feeding end of the strip-shaped film 21 fed by the film feeding means is made to enter between the guide roller 23 and the guide member 26, and then sucked and fixed by the fixing means 22 of the columnar core 17.

The columnar core 17 is rotated by rotating the rotating shaft 18 by the rotation driving means 27 in synchronization with the feeding of the strip film 21. This allows
The belt-shaped film 21 is wound around the outer periphery of the columnar core 17 including the peripheral wall 3b of the bottom member 2 with the vicinity of the pay-out end 21a fixed to the fixing means 22 as a head to form a film cylinder wall (winding step). ). At this time, when the columnar core 17 rotates approximately one rotation or slightly more than one rotation, the dispensing end edge 21 b protruding in a flap shape from the dispensing end vicinity 21 a fixed to the fixing means 22 is positioned on the guide roller 23. Is superposed on the subsequent portion 21c of the film to be formed. That is, since the feeding edge 21b is guided outward by the guide member 26, it is superimposed on the succeeding portion 21c without being wound again by the guide roller 23, and the columnar core 17 stops rotating in that state. . Therefore, in the case of the illustrated embodiment, the rotation driving means 27 for rotating the columnar core 17, the guide roller 23, and the guide member 26
And the winding edge 2 for winding the strip film 21.
A winding means for superposing 1b on the succeeding portion 21c is constituted.

Therefore, a seam welding means 28 and a separating means 29 are provided above the guide roller 23, and are connected to a reciprocating drive means 30 such as a cylinder device for moving the two means 28, 29 up and down. ing. The seam welding means 28 comprises a heating plate, and the separating means 29 comprises a fusing blade or a cutting blade. When the two means 28 and 29 are lowered via the reciprocating drive means 30, the feeding edge 21b and the succeeding part 21c superimposed on the guide roller 23 as described above are welded by the seam welding means 28 and seam welding is performed. A part 31 (shown in FIG. 4) is formed (seam welding step). Then, the seam welding part 31 is separated by the separating means 29.
The subsequent portion 21c of the band-shaped film 21 is cut and separated along (separation step). Thereby, on the columnar core 17,
A film cylinder wall 4 is formed. After that, the seam welding means 28 and the separating means 29 are retracted by the reciprocating drive means 30, and the guide roller 23 and the guide member 26 are retracted by the reciprocating drive means 25.

The columnar core 17 holding the bottom member 2 and the film cylinder wall 4 is continuously moved from the second stage B to the third stage C by rotating the transfer body 15 intermittently.
Transferred to and stopped. Therefore, as shown in FIG. 4, a round welded portion 32 is formed by welding the side edge of the film cylinder wall 4 wound around the peripheral wall 3a of the bottom member 2 over the entire periphery of the peripheral wall 3a (see FIG. 4). Round welding process).

In the case of the illustrated embodiment, a round welding step is performed in a plurality of steps to enable a reliable welding seal over the entire circumference. First, in the third stage C, as shown in FIG. 4 (A), the vertically divided arcuate heat plates 33, 34 are moved forward by advancing / retreating driving means 35, 36 such as a cylinder device, respectively. The upper and lower portions are pressed against the side edges of the film cylinder wall 4 from above and below to form round welds 32a. Then, the arc-shaped hot plate 3
After the members 3 and 34 are retracted up and down, the transfer body 15 is intermittently rotated to transfer the columnar core 17 from the third stage C to the fourth stage D as shown in FIG. And stop, and the arcuate hot plates 37, 3
8 are respectively advanced / retracted driving means 39, 40 such as a cylinder device.
As a result, the film is pressed against the side edge of the film cylinder wall 4 from the left and right to form the right and left round welded portions 32b. Therefore, the hot plates 33 and 34 for performing the first round welding process and the hot plates 37 and 38 for performing the second round welding process constitute round welding means,
Thus, the side edges of the film cylinder wall 4 are welded over the entire circumference of the peripheral wall 3a of the bottom member 2, and the packaging container 1 as shown in FIG.

After the round welding step, the packaging container 1
At the same time, the columnar core 17 rotates the transfer body 15 intermittently so that the fourth stage D to the fifth stage E
After the elapse of a predetermined time, the cooling is naturally performed in a stopped state until it is transferred to the sixth stage F.

Thereafter, the transfer body 15 is further intermittently rotated, and the columnar core 17 holding the packaging container 1 is moved to the position shown in FIG.
As shown in (A), it is transferred to the sixth stage F and stopped,
Then, the packaging container 1 is removed from the columnar core 17 and dropped off (product supply step). In the case of the illustrated example, by switching the valve of the air suction / discharge means 20, the air hole 19 is formed.
When air is blown out from the container, the packaging container 1
And constitutes a removing means of the packaging container 1 by this. However, in addition to the illustrated example, an ejector pin may be provided on the tip end surface of the columnar core 17, or a robot finger or a suction finger may be separately provided. , The packaging container 1 may be pinched and pulled out from the columnar core 17.

The packaging container 1 escaped from the columnar core 17
Is conveyed by a conveyor via a chute or the like and sent to a gusset forming step, where gussets 6 and 6 are formed as shown in FIG. Both sides are welded 8a, 8a, and a semi-finished packaged body 5a having an opening 7a at the center is shipped to a food and beverage maker. Therefore, the food and drink maker or the like who receives the supply can open the opening 7a of the semi-finished package 5a.
1B is subjected to welding 8 as shown in FIG.
The chuck 12 as shown in FIG.
The nozzle 13 with the cap 14 as shown in (D) can be attached or arbitrarily selected.

Of course, the present invention is not limited to the illustrated embodiment, and various design changes or improvements can be made. For example, in the case of the illustrated example, the packaging container 1 in which the cylindrical bottom wall 2 is provided with the cylindrical tubular wall 4 is shown, but the packaging container 1 in which the polygonal bottom member 2 is provided with the polygonal cylindrical tubular wall 4 is shown. Can be manufactured. In this case, if the columnar core 17 is formed in a polygonal columnar shape, it can be easily implemented.

In the above embodiment, the configuration in which the round welding step is performed after the seam welding step has been described. However, the order of both steps can be reversed, or both steps can be substantially performed. May be performed at the same time. Therefore, the six stages A to F as shown in the figure can be freely increased or decreased as necessary, and the number of the columnar cores 17 can be increased or decreased accordingly.

Further, in the above embodiment, in the winding step, the feeding edge 21b of the film 21 wound around the outer periphery of the columnar core 17 is superimposed on the subsequent part 21c, and the superposed part is welded in the seam welding step. Although the method of forming the seam welded portion 31 so as to protrude to the side of the cylinder wall 4 has been described, the seam welded portion 31 may be formed so as not to project from the cylinder wall 4. For example, in the configuration shown in FIG. 3, the guide means 26 is not provided, and the feeding edge 21b is wound around the guide roller 23 by the rotation of the cylindrical core 17, and the winding portion vertically overlaps at the winding portion. The feeding end edge 21b and the subsequent portion 21c are welded from the side with a hot plate to form a seam welded portion, while only the fusing blade is lowered from above to fuse the subsequent portion 21c on the guide roller 23. With this configuration, the seam welded portion is formed integrally with the cylindrical wall 4 itself.
