Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for filling and making a zipper bag, and particularly relates to a bag making process for a zipper bag and a process for filling the zipper bag with contents. Regarding the simultaneous method, it can be used for automatic packaging of foods, etc. in the food and other industrial fields.

[Background technology and its problems]

2. Description of the Related Art A so-called zipper bag is known, which is equipped with a removable zipper member that allows contents such as food to be sealed and packaged, and the bag can be opened and closed again even after it has been opened.

Conventionally, the zipper bags are manufactured separately in advance, and then each of the manufactured zipper bags is put through a filling machine to fill the contents such as food. Filling and sealing methods are known.

However, in this conventional method, the bag making process and filling process are performed separately, so the filling capacity is lower than that of so-called pillow packaging, in which bag making and filling are done at the same time, making it unsuitable for mass production. be.

As an improved method, a zipper bag filling method has been proposed in which zipper bag manufacturing and contents filling are performed simultaneously. (For example, see Japanese Unexamined Patent Publication No. 56-42640).

In this method, one side of a pair of removable zipper tapes is attached to both ends in the width direction of a bag material made of a long strip of film, and then,
This bag material is bent in the direction in which the zipper tape is engaged, and the zipper tape is engaged, and the portions of the zipper tape on the outside of the engaging portion are adhered, and then the bag material is bent in the direction across the bag material. The inner surface of the material is glued to form a bag with one side open, and then the contents such as food are filled through the opening, the opening is glued, and the two adhesive parts are cut and filled. It is used to make bags.

This method allows for bag making and filling at the same time, making mass production possible. Since the process of interlocking the mold chuck tape and the female chaff tape must be carried out during bag making and filling, it is difficult to shorten the filling and bag making time.
, the configuration of the bag making and filling apparatus becomes extremely complicated.

Furthermore, there is a drawback that there is a risk that the male zipper tape may not be properly engaged with the female zipper tape during bag making and filling, or that the engagement may come off, resulting in defective products.

[Purpose of the invention]

An object of the present invention is to provide a method for filling and making zipper bags, which allows the filling and making of zipper bags to be performed quickly and smoothly, and which allows the configuration of the filling and bag making device to be relatively simple. It is about providing.

[Means and effects for solving the problems] The present invention has the following features:
A zipper tape is prepared by fitting a male zipper tape and a female zipper tape in advance, and this is adhered to one shoulder of the bag material, and then the bag material is bent and the other shoulder is attached. At the same time as adhering to the zipper tape, a step of adhering both shoulder parts and a step of adhering a predetermined part across the bag material in the width direction are performed to form a bag shape with one side open; After that, the bag material is filled with food or the like through the opening, and the opening is glued across the width of the bag material, and the part is cut to perform filling and bag making. The process of filling and making bags is relatively small, and there is no risk that the male and female zipper tapes will not fit properly or come off, so the filling and bag-making work can be carried out smoothly and quickly. , it is possible to make the configuration of the filling bag making device relatively simple.

Specifically, a bag material made of a long strip-shaped film, and a pair of zipper tape consisting of a male zipper tape and a female zipper tape that can be attached to and detached from each other in advance. and forming a back surface with respect to the hooking surface of the zipper tape hooked along the longitudinal direction of the bag material at one shoulder part that is located at a predetermined distance from one end in the width direction of the bag material. One of the two sides is adhered, and then the bag material is bent and the other shoulder of the bag material is adhered to the other side of the zipper tape to form the bag material into a cylindrical shape. forming the bag material, and bonding a predetermined portion of the bag material across the bag material in the width direction of the bag material to form a bag shape with one side open; The zipper bag is filled with a filler, the opening is adhesively sealed across the bag material in the width direction of the bag material, and the bag is separated from the adhesive portion to form a zipper bag. ing.

〔Example〕

FIGS. 2 to 11 are diagrams for explaining an embodiment of the zipper bag filling and bag-making method according to the present invention.

FIG. 2 shows a bag material 2 made of a long strip-shaped film, and the bag material 2 is made of polyethylene, vinylon, polypropylene, or other plastic film.

3 to 4 show a zipper tape 3, and as shown in FIG. As shown, the projections 8 of the male zipper tape 4 are engaged with the grooves 10 of the female zipper tape 6.

FIG. 4 is a diagram showing a state in which the zipper tape 3 is engaged.

The fastened zipper tape 3 is wound into a roll as shown in FIG. 5 and prepared.

Next, as shown in FIG. 6, the zipper tape 3 is applied along the longitudinal direction of the bag material 2 to one shoulder part having a predetermined interval from one end in the width direction of the bag material 2. One of the two surfaces constituting the back surface is adhered to the engaging surface.

FIG. 7 shows a sectional view taken along the line A--A in FIG. 1 after adhesion.

Next, the bag material 2 is bent in the direction shown by the arrow q in FIG. Then, both ends of the bag material 2 are adhered.

Note that these steps may be performed simultaneously or may be performed forward and backward.

FIG. 8 shows a state in which it is thus formed into a cylindrical shape, and FIG. 9 is a sectional view taken along the line B--B in FIG. 8.

Note that in FIG. 9, 12 indicates a bonding portion.

Next, a predetermined portion of the bag material 2 is glued across the bag material 2 in the width direction of the bag material 2 to form an adhesive portion 16 to form a bag shape with one side open. A filler 14 such as food is filled from the beginning.

Thereafter, the opening is adhesively sealed across the bag material 2 in the width direction of the bag material 2, and the adhesive portion 18 is formed and then separated from the portion.

FIG. 10 shows a state in which the adhesive and sealing is performed in this manner, and FIG. 11 shows a sectional view taken along the line C--C in FIG. 10.

FIG. 1 is a diagram showing a schematic configuration of an apparatus for carrying out the method of the above embodiment.

In this case, both ends of the bag material 2 are also welded by the first welding device 22 at the same time.

Next, a predetermined portion of the bag material 2 is welded across the bag material 2 in the width direction to form an adhesive portion 18 .

After the bag material 2 is thus formed into a bag with an open top, the filling device 26 fills the bag with a filler 14 such as food through the opening.

Thereafter, the opening is bonded by the second welding device 24, and the bonded portion is separated by the cutting device 28.

This completes the filling and bag making process.

In the above embodiments, each bonding process is performed using a welding device such as a heat seal, but it goes without saying that bonding may be performed using an adhesive or the like.

The embodiment described above has the following advantages.

That is, the zipper tape 3 fitted in advance is adhered to one shoulder of the bag material 2, the approximate center of the bag material 2 in the width direction is bent, and the other shoulder is adhered to the zipper tape 3. Since filling bags are made by filling and making bags, the male zipper tape and the female zipper tape are glued separately, or the male zipper tape and the female zipper tape are fitted together. This process is not necessary.

In other words, the work process of filling and making bags is extremely simple, and there is no inconvenience such as the male and female zipper tapes not being properly engaged or coming loose, and the operation of filling and making bags can be done smoothly and quickly. It is possible to make the configuration relatively simple.

Therefore, the filling bag-making device can be made small and lightweight, which provides great economic benefits.
