BACKGROUND ART Packaging of liquid, paste, granular, etc. articles using packaging bags made of resin film has conventionally been practiced. The production of this type of packaging bag is generally carried out using a vertical pillow type bag making and filling machine.
There, a cylindrical film is formed using sailor and vertical seals rather than coiled film seals.
After the ends are sealed laterally, articles are filled, and the upper part is sealed and cut, and the sealed upper part becomes the bottom to produce a packaging bag continuously filled with articles.

Conventionally, in this type of bag making and filling equipment, it is necessary to use a film with a thickness of 90μ or more in order to package relatively large items, such as about 10 kg, but in reality, it is necessary to use a film with a thickness of 90μ or more. It was impossible to use. In order to make bags with such a thick film, it is necessary to control the tension of the sheet before forming it into a cylindrical shape in the cellar, and to preheat the sheet before bag making. For example, when the lateral seal part was filled with about 10 kg, especially when the temperature was high, the lateral seal part could burst.

用的でない。 The applicant is Utility Application No. 56-54552 (Utility Application No. 57-
No. 167815), as shown in FIG. 1, a heat sealing device 3 is disposed at the sealing portion 2a of the cylindrical film 2 filled with the article 1, and a cutting device 4 is provided directly below the heat sealing device 3 to perform the sealing process. An apparatus has been proposed which strengthens the seal part 2a by immediately cooling the seal part with a cutting device and cutting it at the same time. However, even with this device, the strength of the seal portion was not sufficient to manufacture packaging bags for articles weighing approximately 10 kg, and rupture of the seal portion was unavoidable. Furthermore, as a countermeasure, instantaneous heat bonding using an impulse heater may be considered, but the equipment would be too large and would be impractical.

This invention was made in view of the above, and in particular
A device that manufactures packaging bags by forming a cylindrical film from a resin film sheet of 90μ or more, sealing the ends laterally, and cutting the lateral sealed portion after filling with articles, and sending the cylindrical film downward. A cutting device is disposed directly below a roller that rotates in a manner similar to that and moves in opposition to separate each bag, and a horizontal sealing device that is placed at a distance below this roller, and a forced cooling means is provided to this cutting device. It is an object of the present invention to provide a packaging bag seal cutting device that can manufacture packaging bags filled with articles weighing, for example, about 10 kg.

A roller separates one bag of articles, a roller squeezes out the articles in the cylindrical film, and the one bag of articles is sent downward along with the cylindrical film, and a sealing device heat-seals the cylindrical film in the lateral direction.
Further, the cylindrical film filled with one bag's worth of articles is lowered by a roller, and the heat-sealed portion is cut by a cutting device equipped with a cooling means immediately after the heat-sealing, and is simultaneously cooled.

互いの関係位置は固定されている。 As shown in FIG. 2, a film sheet 11 is transferred from a coil 10 of a resin film sheet to a tension adjusting device 12, and then a cylindrical film 1 is attached to a sailor 13.
4 is formed and sealed in the longitudinal direction by a vertical seal 13a. For example, when forming the cylindrical film 14 using the film sheet 11 of 90μ or more, the film sheet 11 is preheated using a preheating means (not shown) before entering the sailor 13 or the sailor 13. The cylindrical film 14 is the roller 1
5, the tip is laterally sealed by a lateral sealing device 16, cooled by a cutter 20, and the tip is cut. The roller 15 is indicated by arrow P,
P (Fig. 2) shows opposing motion and arrow R.
It is configured to be rotatable as shown by R, and can send the held cylindrical film 14 downward. On the other hand, the material supply device 17 transfers the article to the cylindrical film 1.
4 is filled, one packaging bag 18 is divided by the opposing movement of the rollers 15, 15, and the rollers 15, 1 are separated into one packaging bag 18.
5 and is sent downward by the rotation of rollers 15, 15. Packaging bag 1 sent downward
8' is the horizontal sealing device 16 in the upper sealing part 19.
Immediately thereafter, it is cut by a cutting device 20, which has a forced cooling means. At this time, no article exists within the cylindrical film 14 between the upper seal portion 19 and the roller 15. Therefore, the roller 15 rolls the cylindrical film 1
Since the article is completely squeezed out inside the upper seal portion 19, the seal at the upper seal portion 19 is perfect. Here, the relative positions of the roller 15, the transverse sealing device 16 and the cutting device relative to each other are fixed.

いる。 In FIG. 3, the packaging bag seal cutting device of the present invention includes a horizontal sealing device 16 and a cutting device 20 disposed directly below the horizontal sealing device 16. Horizontal seal device 16
consists of a pair of heating members 16a and 16b containing heating means (not shown) such as nichrome wire, which move together in the direction of arrow A to seal the packaging bag 18 at the sealing portion 19. The cutting device 20 consists of a pair of cutting members 20a and 20d. Cutting member 20
Cooling fluid passages 21 and 22 are built into the cutting members a and 20b, respectively, and cooling fluid flows through the passages 21 and 22 to constantly cool the cutting members 20a and 20b.

することはない。 In use, the packaging bag 18 is formed filled with articles as illustrated in FIG.
Sealing is performed at the seal portion 19 by the lateral seal device 16 . At the sealing portion, the article inside the film is almost completely squeezed out by the roller 15. The sealed packaging bag 18 is immediately lowered by the width of the seal.
18'' and are cut by the cutting device 20. At this time, each cutting member is cooled by the cooling fluid flowing through the passages 21 and 22, so the seal portion 19 is cut and simultaneously cooled. Therefore, the seal portion 19 is tightly sealed.The roller 15, the horizontal sealing device 16, and the cutting device 20 operate in accordance with the timing of dividing, sealing, and cutting one packaging bag.Therefore, the inside of the packaging bag is Even if the weight of the article is large, for example around 10 kg, the seal part 1
9 will never explode. Further, even if the temperature of the filling is somewhat high, the adhesive strength of the seal portion 19 is high and it will not burst.

Using a resin film seal with a thickness of 90μ or more,
This film seal is preheated to form a cylindrical film using a sailor or the like, an article is fed into this cylindrical film, the product is sealed horizontally to continuously form a packaging bag in which the article is enclosed, and each sealed portion is cut. When manufacturing a large number of packaging bags continuously, the products inside the cylindrical film are completely squeezed out using rollers, and in this state, immediately after the horizontal sealing, the horizontal sealing part is cut using a cutting device equipped with a cooling means, and at the same time, the horizontal sealing part is rapidly cooled. For example, 10Kg
It is possible to manufacture packaging bags that are relatively heavy and cannot be manufactured using conventional equipment.
