Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and an apparatus for manufacturing a sealed packaging bag in which two or more types of seasonings and the like are housed in the same packaging bag.

[Conventional technology]

BACKGROUND ART Today, simple packaging bags are widely used as seasonings for instant ramen noodles and the like, in which liquids such as seasoning liquid and oil or liquids and powders are separately stored in the same packaging bag. This is because it has advantages such as low packaging cost and low bulk. For example, in a bag of this type, as shown in FIG. 4, a partition is provided parallel to the vertical edge of the rectangular bag, and the area defined by the partition is filled with liquid, etc. There is something I did.

However, when two types of contents are taken out at the same time from a packaging bag of the form shown in FIG. 4, there is a problem that the bag is difficult to open because the distance to cut the bag becomes long.

This problem can be solved by making the packaging bag as shown in FIG. However, a packaging bag that separately accommodates two or more types of contents is usually of the type shown in Figure 4, and is manufactured, for example, by the method described in Japanese Patent Publication No. 57-59127. If applied as is to the packaging bag shown in FIG. 1, various problems will occur. That is, in the bag shown in FIG. 1, there is a diagonal seal part in the inner partition, so if this seal is formed with the first roll, one of the content storage areas will be formed here, and the content will not be filled. The nozzle must be installed above the first roll. In such a case, it is not possible to fill the liquid, etc. until the above-mentioned content storage area is almost completed, so the liquid, etc. to be filled must be filled until the partition is sealed to the top of the packaging bag. The content storage area must be filled within a short period of time from when the top edge of the packaging bag is sealed. Therefore, since the filling liquid etc. must be discharged all at once from the nozzle for filling the contents, the liquid etc. may splash back and splash on the outside or the sealing part, resulting in excess or deficiency of the stored amount and burning of the sealing part. When the product value decreases, problems arise.

On the other hand, if the above-mentioned filling time were to be extended, the rotation of the rolls would have to be slowed down in order to fill the bags without discharging the liquid all at once, which would reduce the productivity of the packaging bags, resulting in problems such as the following. .

[Problem that the invention seeks to solve]

Therefore, an object of the present invention is to provide a manufacturing method and apparatus that can efficiently and easily manufacture a sealed packaging bag having a configuration in which the inner partitions are concentrated at the corners of the packaging bag as shown in FIG. shall be. Another object of the present invention is to provide a method and apparatus for sealing contents that can easily fill different contents separately and store a uniform amount of contents.

[Means for solving problems]

In the present invention, along the longitudinal direction of the packaging bag sheet,
This was done based on the knowledge that the above-mentioned problems can be effectively solved by forming the partition halfway and then forming the diagonal portion of the partition seal.

That is, in the present invention, a compartment-forming partition provided for separately accommodating two or more kinds of substances in the same sealed packaging bag extends from the upper edge of the packaging bag in the vertical direction. A method for manufacturing a sealed packaging bag formed by sealing up to a point and diagonally sealing from the point toward one of the corners at the lower edge of the packaging bag, comprising: forming the packaging bag. Step of sealing along the lengthwise direction of the packaging sheet to form the partition partway: Seal the lower edge of the packaging bag forming sheet and sealing the diagonal part of the partition to complete the partition.

This is an apparatus for manufacturing a sealed packaging bag, characterized in that a nozzle for filling the contents is provided.

In the present invention, the above-mentioned packaging bag forming sheet includes:
Cylindrical sheet with open upper and lower edges, 1
A sheet formed by folding a sheet into two along the lengthwise direction or a sheet formed by stacking two sheets can be used. When using a sheet formed by folding one sheet into two along the lengthwise direction, a seal-forming protrusion for sealing the released longitudinal edges is placed on the first roll. established in
Preferably, the longitudinal edges are sealed at the same time as the longitudinal partitions. On the other hand, even when two sheets are used, seal-forming protrusions are provided on the first roll to seal the edges on both sides in the vertical direction, and at the same time as the partitions along the vertical direction, the vertical Preferably, the edges on both sides of the direction are sealed.

Hereinafter, details of the present invention will be specifically explained using the drawings.

As shown in FIG. 1, the sealed packaging bag 1 manufactured according to the present invention has a compartment forming partition 2 provided for separately accommodating two or more types of substances in the same packaging bag. Starting from one location on the upper edge 3 of the packaging bag 1, the seal is applied along the longitudinal direction of the packaging bag 1 to a location 4 in the middle of the packaging bag 1, and from the location 4 to one corner 5 of the packaging bag 1. It is in a sealed form.

Various types of packaging bags 1 as described above are used, such as one in which one sheet is folded and the open side edges sealed, and two sheets in which the open side edges are sealed. Suitable materials for the sheet used here include polyolefin resins such as polypropylene and polyethylene, and thermoplastic resins such as nylon and polyester. In addition, in order to improve the storage stability of the contents, a single film or a laminate film of polyvinylidene chloride, ethylene vinyl acetate copolymer, nylon, etc., or a laminated film of aluminum foil or the like is also preferable. Furthermore, depending on the contents, cellophane or laminated paper may also be used. Moreover, at least one surface can be made transparent so that the contents can be seen through.

In addition, the above-mentioned sealed packaging bag 1 can contain powder, liquid,
Various things such as paste are stored. Specifically, various combinations such as seasoning liquid such as soy sauce and oil, coffee concentrate and cream, or wasabi and soy sauce can be stored.

A method of manufacturing the above-mentioned sealed packaging bag 1 using a single sheet folded in the vertical direction as a packaging bag forming sheet will be explained with reference to FIGS. 1 to 3. First, the packaging bag of the forming sheet is sealed in the vertical direction. That is, as shown in FIG. 2a, the vertical side edges 16 of the packaging bag forming sheet 11 and a part 17 of the middle partition section (hereinafter referred to as "vertical middle partition section") along the longitudinal direction are sealed at the same time. .

Vertical side edge 1 of the above-mentioned packaging bag forming sheet 11
Reference numeral 6 denotes the open vertical edge of one sheet folded, and by sealing this edge, a cylindrical bag is first formed and the bag is moved to the next step.

Moreover, the vertical middle partition part 1 of the packaging bag forming sheet 11
7 is parallel to the vertical edge 16 of the packaging bag forming sheet 11 or the lower edge 1 of the packaging bag forming sheet 11
8, the sheet 11 is sealed along the longitudinal direction up to a midway point 14 of the sheet 11. in this case,
It is preferable to seal as close to the lower edge 18 of the sheet 11 as possible. This makes it possible to shorten the time required to seal the remaining partitions from one corner 15 of the lower edge 18 of the sheet 11 to the lower end 14 of the vertical partition 17 in the next step. Therefore, the shorter the time, the more time can be taken to fill the liquid etc.

The sealing in the above-described process is performed by the first roll 29 shown in FIG. 1st roll 29
is provided with a protrusion member 30 around the end of the cylindrical roll circumferential wall surface, and another protrusion member 31 is provided at intervals in the circumferential direction on the circumferential wall surface other than the end, It is formed from a pair of laterally symmetrical rolls so as to sandwich the sheet 21 from both sides. Note that a plurality of protruding strip members 31 can be provided to form three or more divisions.

The protrusion member 30 provided around the end of the peripheral wall of the cylindrical roll in the first roll 29 is provided to seal the vertical open side edge 22 of the folded sheet 21 and form a cylindrical bag. It is something that

Further, another protrusion member 31 provided at intervals in the circumferential direction on the peripheral wall surface other than the above-mentioned end portions,
This is provided to seal the vertical middle partition portion 27 described above.

The distance between each of the plurality of protrusions provided as described above is determined from at least the upper edge 3, the lower edge 8, and the lower end 4 of the above-mentioned inner partition to the corner of the packaging bag in the next step. Diagonal partition seal portion 9 up to 5 (hereinafter referred to as “diagonal partition portion”)
) may be provided so that it can be sealed.

Further, the above-mentioned protruding member 31 can be provided at an appropriate location on the outer circumferential wall surface other than both ends of the first roll 29. However, filling nozzles 32 and 32' for filling liquid etc. are inserted into the gaps partitioned by the protruding strip member 31, that is, the gaps created by the protruding strip member 31 and both ends of the roll. It must be set up so that it can be done.

Furthermore, the height of the protrusion member installed on the first roll 29 is such that when the protrusion parts of the rolls in symmetrical positions are in contact with each other, the above-mentioned filling nozzle is placed in the gap between the peripheral wall surfaces of each roll. It is desirable to determine the gap so that 32, 32' can be inserted up to the upper part 34 of the second roll 33, specifically, a gap of about 0.2 to 3.0 cm.

Next, the cylindrical bag 23 formed by the first roll 29 is transferred by the rotation of the roll, and the cylindrical bag 23 formed by the first roll 29 is transferred to the second
As shown in Figure b, the lower edge 18 and diagonal partition 19 of the bag body 23 are sealed with a second roll 33, and the respective compartments formed by the seals are filled with contents such as liquid. .

The portions to be sealed as described above are sequentially sealed starting from the lower edge 18 of the bag body 23 by rotation of the roll. and one corner 15 of the lower edge 18.
When the packaging bag is sealed up to the lower end 14 of the vertical middle partition 17, the middle partition of the packaging bag is formed. Therefore, it becomes possible to immediately fill the compartment formed by the partition with liquid at that point, and it takes a long time from the above-mentioned point to sealing the upper edge 3 of the packaging bag 1. Can be filled inside. That is,
The vertical middle partition part 17 of the above-mentioned packaging bag 1 is
By providing it with a roll, the above-mentioned time can be increased. Therefore, the filling nozzles 32, 3
There is no need to discharge liquid etc. all at once from 2'.
Splashing of liquid etc. can be effectively prevented.

Next, as shown in FIG. 2c, the upper edge 13 of the packaging bag divided by partitions and filled with liquid or the like is sealed. As a result, a sealed packaging bag 1 is completed in which each section divided by the inner partition is filled with liquid or the like. That is, by continuously repeating the above-described steps, the sealed packaging bag 1 can be efficiently manufactured, and productivity can also be improved.

Note that the above sealing is performed under known heat sealing conditions.

〔Effect of the invention〕

In the present invention, since the vertical and middle partitions of the packaging bag are sealed and formed in advance by the first roll, sufficient time can be taken for filling liquid, etc. in the next step. Therefore, there is no need to discharge the liquid etc. all at once from the filling nozzle, so it is possible to prevent the liquid etc. from scattering. Therefore, a uniform amount of liquid etc. can be filled into the packaging bag. Moreover, since the liquid and the like do not adhere to the sealed area, there is no possibility that liquid or the like is likely to burn at the sealed area after heat sealing and that the appearance of the packaging bag becomes poor. The following remarkable effects can be obtained.
Furthermore, significant effects such as improved productivity of packaging bags can also be obtained.
