BACKGROUND OF THE INVENTION
The present invention relates to a method for manufacturing a package and a bag making and packaging apparatus.
[0002]
[Prior art]
When selling a relatively small product, when packaging the product in a bag, the bag is manufactured and the product (hereinafter referred to as “packaged product”) is packed into the bag. The work was usually done separately.
As shown in FIG. 9, as an example of a bag 100 used in this type of packaging, a header portion 102 having a plate shape and slightly hardened is provided in the form attached to the bag mouth 101. There is something.
[0003]
The header 102 displays the product name, quality, and the like of the packaged product 103, and depending on the product, a suspension hole 104 for suspension to an exhibition rack or the like is provided (actual opening). (See Japanese Patent Publication No. Sho 62-179941, Japanese Utility Model Publication No. 1-15639).
In order to form such a header portion 102, an extension piece 105 extending from one side of the bag mouth 101 is formed on a film, which is a bag forming material, and a paper or resin sheet is formed by the extension piece 105. The header core material 106 made of the product is encapsulated, and then, the adhering portion 107 is formed by heat welding or the like in the superposed portion after enveloping.
[0004]
Further, the extension piece 105 has a length that causes a surplus length portion to pass through the fixing portion 107. The surplus length portion is used as a lid piece 108 and is provided on the outer surface side of the bag mouth 101 in advance. The bag mouth 101 is closed by being pressed to 110.
[0005]
[Problems to be solved by the invention]
As described above, conventionally, the operation of manufacturing the bag 100 and the operation of packing the packaged product 103 into the manufactured bag 100 have been performed separately.
That is, although illustration is omitted, the bags 100 manufactured in a separate process are once again stocked in a cassette or the like, and while the bags 100 are taken out one by one from this stock state, their positioning and the opening of the bag mouth 101 are opened. Thus, the articles 103 to be packaged are inserted into the individual bags and closed by the lid pieces 108.
[0006]
For this reason, the work efficiency is poor, and as a result, the entire product (packaging body) leads to high costs.
The present invention has been made in view of the above circumstances, and by performing a series of operations from the stage of manufacturing a bag to the stage of packing a packaged product at once, work efficiency is improved. An object of the present invention is to provide a method for manufacturing a package and a bag making and packaging apparatus that can improve the cost and reduce the cost of the entire product (package).

That is, in the method for manufacturing a package according to the present invention, in the process of folding a film to form a bag, the film is folded to form a bag bottom, and the length of the bag bottom is set according to a predetermined bag width. Then, after fixing both side edges of the front and back folded pieces along the cutting line, the packaged product is inserted into the bag original shape obtained by these, and then the header portion is formed close to the bag mouth. At the same time, the process until the bag mouth is sealed is continuously performed.
[0008]
More concretely speaking, the method for manufacturing a package according to the present invention folds the band-shaped film in half in the direction in which the band width is clogged, and enlarges the lower folded piece and makes the upper folded piece smaller. The bottom of the bag is formed at the folding position, an adhesive band is formed near the tip side of the upper folded piece, and the upper and lower folded pieces are cut along this cutting line while cutting the longitudinal direction of the film according to the predetermined bag width. The bag original form (the original form of the bag) is formed by fixing the.
After the packaged product is inserted into the original bag shape, the overhanging portion of the lower folded piece is folded back to form a header portion, and the folded-up front side appropriate place is fixed up and down, and the folded portion is folded upward from the fixed portion. A lid piece that extends to cover the piece is adhered to the adhesive band of the upper folded piece, and a suspension hole is formed at a suitable position in a region corresponding to the header portion.
[0009]
As a series of such flows, the entire work from the stage of making bags to the stage of packing packaged goods is performed consistently, improving work efficiency and reducing the overall product (packaging body). Cost reduction is achieved.
On the other hand, in the bag making and packaging apparatus according to the present invention, the film supply section, the folding section, the equipment attachment section, the bag making section, the bag filling section, the header forming section, and the finishing section perform a series of continuous operations.

Moreover, these parts 2 to 8 are installed in series along the work flow so that they can perform consistent continuous work.
[0014]
The film supply part 2 is a place which sends out the strip | belt-shaped film 10 used as the forming material of a bag to the longitudinal direction.
As a specific structural example, the film 10 is initially prepared in a rolled-up state, and this is held on a reel 11 so as to be rotatable, and a reel motor or a drive pinch roller or the like (both not shown) or a constant speed or dancer. What is necessary is just to let it roll out intermittently using a roll (not shown) etc.
The folding unit 3 is a place where the film 10 sent from the film supply unit 2 is folded in half in the direction in which the band width is reduced.
[0015]
As a folded form at this time, a folded piece (hereinafter referred to as a “lower folded piece”) 10A that is the lower side in the folded state is enlarged, and a folded piece that is the upper side in the folded state (hereinafter referred to as “the lower folded piece”). 10B) is made smaller.
The film 10 folded in such a state forms the bag bottom 120 (see FIG. 9) at the creased position.
As a specific structural example, the film 10 fed from the film supply unit 2 is brought into contact with the anti-floating roller 12 that presses the width direction from above, and the width direction both ends of the film 10 are brought together, and At the same time, picking up appropriate positions in the middle portion in the width direction of the film 10, pulling them up, and keeping the state in this state laterally (direction perpendicular to the feeding direction from the film supply unit 2 in a plan view) A structure that pulls out to) may be adopted.
[0016]
The equipment attachment part 4 has a core material pasting part 16 and an adhesive band forming part 17 (shown in an enlarged manner in FIG. 3).
The core material pasting portion 16 is where the core material for header 106 (see FIG. 9) is attached to the lower folded piece 10A of the film 10 that has passed through the folding portion 3.
In the lower folded piece 10A, the header core member 106 is attached at a position closer to the root (ie, with respect to the bag mouth 101), in the portion where the lower folded piece 10A projects from the upper folded piece 10B. The part immediately outside of
[0017]
Here, the core material 106 for the header may be made of paper or resin, but is initially prepared as a thin and continuous tape shape and wound in a reel shape. Is preferred.
Then, the reel of the header core member 106 is held rotatably, and the feeding end of the header core member 106 is engaged with the roller pair 20 (see FIG. 4) for pinching the film 10 together. You can do it.
In this way, the header core member 106 is automatically fed out in synchronism with the conveyance drive of the film 10. That is, the film 10 is overlaid in the tape shape along the longitudinal direction of the film 10.
[0018]
At this time, for example, an adhesive or the like may be provided on the back surface of the header core member 106 so that the header core member 106 is fixed to the film 10.
However, in the case where the header core member 106 is made of a resin sheet material, the bag making unit 5 disposed immediately downstream of the fixture attachment unit 4 includes the header core member 106 and the film 10 in the process. Since the fixing action can be obtained, the fixture attachment part 4 may simply superimpose them.
The adhesive band forming part 17 is a place where an adhesive band 110 (see FIG. 9) is formed near the tip side of the upper folded piece 10B of the film 10 that has passed through the folding part 3.

Among these, the execution timing of the cutting operation is set so as to coincide with the time when the transport amount in the longitudinal direction of the film 10 corresponds to the bag width of the bag 100 to be obtained or is slightly larger than this.
As a cutting method, it is most preferable to employ a fusing method using a fusing press 25 as illustrated.
Further, the fixing work is to fix the lower folded piece 10A and the upper folded piece 10B of the film 10 along the cutting line generated by the cutting work. However, if the fusing method is adopted for the cutting operation as described above, a welding action can be obtained simultaneously with this cutting, and thereafter, it is not necessary to perform the fixing operation again.
[0021]
That is, since the cutting operation and the fixing operation can be performed at once, simplification as the apparatus and high operation efficiency can be obtained.
However, as the cutting operation, a cutting device of a cut-off method or a traveling cutter method, a shearing (guillotine) press, or the like can also be adopted. What is necessary is just to carry out by sonic welding.
The bag filling unit 6 is a place where the article 103 to be packaged is inserted into the bag original form 125 from the bag making unit 5.
[0022]
As a specific structural example, an insertion guide 27 (in the example shown in the figure, it has two pairs of guide rails 28 but may be a chute-like one) is inserted into the bag mouth 101, What is necessary is just to push in the to-be-packaged goods 103 with a pusher (not shown), making it fit.

It is the place where the folded back and the folded back side appropriate place is fixed up and down.
[0023]
By this fixing, a fixing portion 107 is formed and a lid piece 108 is formed. Needless to say, not only the fixing portion 107 but also both side edge portions of the fixing portion 107 may be fixed in a plane U shape.
Although not shown in the drawings as a specific structure for performing the folding, for example, a plurality of pushers that perform advancing and retreating in a plurality of directions necessary to bend the protruding portion of the lower folded piece 10A are appropriately combined. It should be.
Further, as a specific structure for fixing, a press apparatus having a heating type or ultrasonic type welding head 30 in which a plurality of welding spots are arranged in a serrated shape as shown in FIG. 7 may be used.
[0024]
The finishing portion 8 adheres the lid piece 108 extending from the fixing portion 107 to the bag original shape 125 conveyed through the header forming portion 7 by pressing the lid piece 108 against the adhesive band 110 of the upper folded piece 10B. This is where the hanging hole 104 is formed at a suitable position in the region corresponding to the material 106.
As a specific structure, a press (not shown) may be used for adhesive pressing, and a punch 31 as shown in FIG.
As is apparent from the above description, in the bag making and packaging apparatus 1, the film supply unit 2, the folding unit 3, the equipment attachment unit 4, the bag making unit 5, the bag filling unit 6, and the header formation. A part 7 and a finishing part 8 are provided, and a series of operations from the stage of manufacturing the bag 100 to the stage of packing the packaged articles 103 can be performed at once.

Therefore, the overall work is performed with high efficiency without any interruption.
FIG. 10 schematically shows the configuration of a second embodiment of the bag making and packaging apparatus 1 according to the present invention.
In the bag making and packaging apparatus 1 according to the second embodiment, the most different point from the bag making and packaging apparatus 1 according to the first embodiment described above is that the equipment attachment unit 4 has an upper folded piece with respect to the film 10 that has passed through the folding part 3. The adhesive band 110 is only formed near the tip side of 10B.
[0026]
That is, the header core member 106 (see FIG. 1) is not attached to the lower folded piece 10A.
Accordingly, the header forming section 7 naturally operates to simply fold the appropriate position of the lower folded piece 1OA as it is when the header section 102 is formed with respect to the bag original shape 125 that has passed through the bag filling section 6 (that is, the header core material). No operation for wrapping 106 is required.
Therefore, in the bag making and packaging apparatus 1 according to the second embodiment, as shown in FIG. 11, the bag 100 in a state where the core member 106 is not enclosed in the header portion 102 is manufactured. .
