Description

  The present invention relates to a packaging bag, and is a packaging bag for continuously manufacturing a packaging bag by using a film while putting liquid or powder contents into the film, and folding the film inside the packaging bag in particular. The present invention relates to a manufacturing apparatus, a manufacturing method, and a manufacturing program for a packaging bag having portions.

    2. Description of the Related Art Conventionally, pump-type containers that use a suitable amount of liquid such as shampoo and hand soap with a pump have been widely used. And in recent years, even if the liquid inside the pump-type container runs out due to the problem of garbage such as disposable containers, the container is not discarded, but the contents filled in the refill-only packaging bag are refilled into an empty pump-type container. In order to reduce dust, the pump-type container is reused. As a manufacturing method of these packaging bags, as a bag making filling packaging method and a self-supporting bag making filling packaging machine (see, for example, Patent Document 1) for filling a package while forming a packaging film in a cylindrical shape, A back-sealing seal process for forming a back-sealing seal portion by sealing both side ends overlapped along the running direction of the packaging film of the tubular packaging film, the tubular shape facing the portion to which the back-sealing seal portion is applied A hem forming step of forming a pair of hems spaced apart in the circumferential direction of the tubular wrapping film in a portion of the wrapping film and forming a pair of hems along the traveling direction of the wrapping film, and sealing the pair of hems to form a pair of hem seal portions Forming a hem sealing step, folding a step of folding the tubular packaging film inwardly at a circumferential intermediate position between the pair of hem sealing portions, and filling the tubular packaging film with a package The tubular packaging film is spaced apart in the packaging film running direction by placing the pair of hem seal portions overlapped at one end and the folding step at the filling step and the folding step at the other end. There is a method for manufacturing a self-supporting packaging bag comprising a horizontal sealing step in which a horizontal seal portion is formed between a self-supporting packaging bag formed by heat sealing in a lateral direction at a position.

Since this Patent Document 1 is manufactured by vertical bag making and filling packaging, a manufacturing method is disclosed in which air and dust are hardly mixed in the packaging bag. This conventional example is described in FIGS.
11 is a front view of a conventional example, FIG. 12 is a side view of FIG. 11, FIG. 13 is a cross-sectional view along AA, FIG. 14 is a cross-sectional view along BB, and FIG. .
Each configuration includes a film 1, a feed roll 2, a back-sealed seal means 3, a hem seal means 4, a feed roll 5, a feeding cylinder 6, a folding means 7, a transverse sealing means 8, a dividing means 9, a content 11, and a bag inner fold. The position 15, the folding depth reference 16, the feeding direction 20, the packaging bag 30, and the seal portion 29.

The production procedure is as follows. A roll-shaped film (not shown) is fed out by a feed roll 2 and a feed roll 5, and the film 1 is wrapped around an input cylinder 6 and the edge of the film is sealed by a back-sealing seal means 3 to form a cylinder. The upper part of the bag 30 is configured. Next, the hem seal means 4 forms a hem seal to form the bottom of the packaging bag 30. Next, a folding portion is formed by the folding means 7 so as to be folded inside the cylindrical film. Thereafter, the side portion on one side of the packaging bag 30 is sealed by the lateral sealing means 8 and the contents 11 are removed from the input cylinder 6. After the charging, the remaining side portion is sealed and cut with a cutter of the dividing means 9 to manufacture the packaging bag 30.
Here, the AA cross-sectional view when the contents are charged is the folding position 15 on the inner side of the bag is folded up to the folding depth reference 16 which is the depth of folding into the inner side of the bag. The packaging bag 30 can be formed by being laterally sealed by the lateral sealing means 8.
Further, since the content of the BB cross-sectional view when the contents are charged is small, the folding position 15 inside the bag is not deformed.

JP 2001-206307 A

  Here, FIG. 16 to FIG. 18 show diagrams when many contents are put, and FIG. 16 is a front view of the apparatus. FIG. 17 is a cross-sectional view taken along the line CC. FIG. 18 is a sectional view taken along the line DD, showing a difference E between the folding position 15 inside the bag and the folding depth reference 16. As shown in the DD cross-sectional view, when the contents 11 are filled into the bag in the filling step, the folding position 15 inside the bag that is folded inward spreads outward. Furthermore, the cross-sectional view taken along the line C-C, where the lateral seal is performed, shows that the folding position 15 of the C-C cross-section is pushed outward by expanding the lower surface of the bag relative to the position of the apparatus, and the folding depth reference 16 And the folding position 15 on the inner side of the bag are shifted by the length of E and are not the same position. Therefore, there is a problem that when the heat sealing is performed in the lateral direction, the sealing cannot be performed at the correct position. In particular, a heavy content such as a liquid tends to be deformed more easily than a light content such as a pockone, and tends to be difficult to seal sideways. For this reason, it has been necessary to devise measures such as limiting the amount of contents to be small so that the crease spreads outside the bag and does not shift the position, or making the film material hard.

  An object of the present invention is to solve the problems of the prior art, and even if the contents of the folds of the bag folded inside the bag by the folding means are not easily misaligned, the amount of the contents is reduced. It is to provide a packaging bag manufacturing apparatus, a manufacturing method, and a manufacturing program that can be laterally sealed without any limitation.

In order to achieve the above object, a packaging bag manufacturing apparatus according to the present invention folds a film inside a bag by a film feeding means, a folding means, a vertical sealing means, and a horizontal sealing means, and a side portion with respect to the position of the apparatus. After molding the bag with the bottom part sealed, the contents are put into the bag by the contents throwing means, and the top part is sealed and sealed by the transverse sealing means, and divided into each packaging bag by the dividing means. In the packaging bag manufacturing apparatus, the position where the film is folded inside the bag is pressed, the position shift prevention means is closed when the bag is folded inside, and the part that is not folded inside the bag can be opened partially The feed roller mechanism can be opened and closed .

Moreover, the manufacturing method of the packaging bag which concerns on this invention folds a film inside a bag by a film feeding process, a folding process, a vertical sealing process, and a horizontal sealing process, and seals a side part and a lower surface part with respect to the position of an apparatus. After the molded bag is formed, the contents are put into the bag by the contents feeding process, and the upper surface portion is sealed and sealed in the horizontal sealing process, and the packaging bag is divided into the respective packaging bags by the dividing process. In the method, the position where the film is folded inside the bag is pressed, the position misalignment prevention process closes the part folded inside the bag, and the part not folded inside the bag can be opened and opened partially openable It is a roller process . The packaging bag manufacturing program according to the present invention includes a film feeding process procedure, a folding process procedure, a vertical seal process procedure, and a horizontal seal process procedure for folding the film inside the bag, After forming the bag with the bottom surface sealed, the contents are put into the bag by the contents charging process procedure, and then the upper surface part is sealed and sealed by the horizontal sealing process procedure. The manufacturing program of the packaging bag divided into two is a feed roller processing procedure that can be partially opened and closed that can close the portion folded inside the bag and open the portion not folded inside the bag .

  Even if the contents are put into the bag by the above configuration and the bag spreads, the bag folded inside the bag at the place where the lateral sealing is performed by pressing the place where the fill bag is folded inside the bag by the clamp mechanism The crease is less likely to be misaligned. For this reason, it is possible to seal at the correct position by the horizontal sealing means, and there is an effect that the horizontal sealing can be performed without restricting the amount of the contents to be small.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following description, it will be described as a self-supporting packaging bag for liquid, but it may be a packaging bag for liquid, mucilage, and powder that does not stand by itself. Further, the folding means is described as a manufacturing apparatus in which the film is formed into a cylindrical shape and the packaging bag is folded inward by the folding means after the cylindrical means. However, the folding means may be a manufacturing apparatus that folds without using the cylindrical means. Further, the present invention is not limited to these drawings. Furthermore, the same reference numerals are used for portions having the same names in different drawings.

Embodiment 1 of the production apparatus of the present invention is shown in FIGS.

Consists of.

  The main material of the film 1 constituting the packaging bag is a multilayer film of synthetic resin, which can be welded on one side, and the thickness of the film is preferably 20 to 500 μm, and the thickness is selected depending on the material and application. The multilayer film is a composite film of a base film having strength and various barrier properties and a heat sealable film. For example, the base film is a stretched or unstretched film of a thermoplastic resin plastic such as polyester, polyamide, polypropylene, saponified ethylene / vinyl acetate copolymer. And the thickness of a base film is selected from the thing suitable for the rigidity of 10-50 micrometers, heat resistance, and workability | operativity.

  The film 1 is fed by the feed roll F2 and the feed roll G5, and is wound around the charging cylinder 6. The back-sticking sealing means 3 and the hem sealing means 4 serving as vertical sealing means for sealing the film 1 in the feeding direction 20 constitute a mechanism and a heater for feeding the film 1 therebetween. The folding means 7 folds the inside of the cylindrical film while sealing the top and bottom of the packaging bag 30. Next, the sensor confirms that the vertical seal and folding have been completed to the required length, and stops feeding at the required length. Next, after sealing by the horizontal sealing means 8, one side portion of the packaging bag 30 is sealed by cutting the center of the horizontal seal by the dividing means 9 serving as the dividing means 13. Next, the feeding is started and the vertical seal and the folding portion are inserted until the required length is reached. Next, when the required length is reached, the feeding is stopped to form a bag in which one side, top and bottom of the packaging bag 30 are sealed.

Next, a portion where the film is folded inside the bag is pressed by a clamp mechanism H18 serving as a displacement prevention means. The clamp mechanism H18 has non-slip urethane rubber on the clamp surface, and the film 1 can be supported without slipping even if the contents get into the bag. Because it does not, there is a gap for the contents to enter the inside of the bag. In addition, since the clamping mechanism H18 is positioned on the side of the feed direction 20 with respect to the lateral seal means 8, the lateral seal is deformed because it is clamped by the clamp mechanism H18 just before the location where the lateral seal is performed even if the bag spreads. Can be sealed at the correct seal position without causing
