Now, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 and FIG. 2 show a first embodiment. A packaging material having heat sealability, that is, a heat-welded film (hereinafter referred to as a film) is wound in a roll shape, and the wound film 1 is fed out. The wound vertical sealing tape 5 is fed out at a portion in a flat state between the feeding rolls, and is heat-sealed with the film 1 along a surface of one end of the film 1 with a strong sealing property. The film 1 having the longitudinal sealing tape 5 welded to one end surface of the film 1 is further unwound and formed into a cylindrical shape while being wound around a former 3 asymmetrically provided on the upper side of the filling inlet 2. One end side where the vertical seal tape 5 is welded and the other end side without the vertical seal tape 5 are overlapped in a palm-like shape, and the vertical seal base 6 is shifted by a predetermined amount to the left or right side instead of the center. Therefore, the films 1 are vertically bonded without being bonded to each other continuously or intermittently.
As described above, one end of the film 1 is strongly sealed through the vertical seal tape 5 and the other end of the film 1 is heat-sealed by abutting in the palm-like shape of the tubular film 7 that has been formed, and the other end. Is sealed to the other end of the film in an easily opened state. The vertical seal part shifted to either the left or right side is folded so as to be brought into close contact with the tubular film 7 so that it is guided by a guide or the like and the easy-open seal side is inside. Therefore, as a result of adopting this configuration, as a package filled with food to be cooked by a microwave oven or the like, when heated by a microwave oven or the like, the internal pressure increases due to water vapor inside the bag of the package or thermal expansion of the internal air. Even so, the internal pressure can be released to the outside of the bag body from the easily opened and sealed part, and the expansion pressure prevents the bag from bursting and the contents from being scattered, and the inside of the microwave oven from being soiled. Can do.
As described above, since the vertical sealing tape 5 is heat-sealed at the portion where the film is flat, positioning can be ensured at the end surface portion of the film 1, and the vertical sealing tape 5 meanders at the film end surface portion. Therefore, it can be accurately welded to a predetermined site.
Further, the vertically sealed tubular film 7 is pulled down, and the first one is to form a bottom seal by intermittently heat-sealing the bottom 8 with a horizontal seal base 9, and in this state the contents are Filling and charging is performed from the charging and charging port 2. When the contents are filled, the bottom portion 8 of the cylindrical film 7 to be the next package is also laterally sealed at the same time by horizontally sealing the upper part 10 of the cylindrical film 7 containing the contents with the horizontal seal base 9. Sealed, cut in the middle of the horizontal seal, and the package 8 is sealed, and at the same time the bottom 8 of the next cylindrical film 7 is horizontal sealed. It is a vertical feed continuous bag making and filling and packaging apparatus that performs continuous bag making and filling and packaging continuously by repeating what has been described.
In addition, the feed control for feeding / stopping the film 1, the feed control for feeding / stopping the vertical seal tape 5 (control performed in synchronization with the feed control for the film 1), the adhesive seal for the vertical seal tape 5 and the film 1 Various drive controls for the base, the vertical seal base 6 and the horizontal seal base 9 are conceivable. However, in the present invention, since control is not particularly the gist of the invention, description thereof is omitted.

Next, a second embodiment will be described based on FIGS.
The vertical feed continuous bag making and filling and packaging apparatus of the second embodiment is different from the one described in the first embodiment in that the way of interposing the vertical sealing tape 5 is changed. It is a vertical pillow type continuous bag making filling and packaging device that fills and seals the contents while feeding the film 1 continuously or intermittently in the form of a roll, While being wound around the provided asymmetric former 3, a cylindrical shape is formed. At this time, the both ends of the film 1 are shifted by a predetermined amount to the left or right instead of the center by being guided by the asymmetric former 3. It is formed in a cylindrical shape as if it were abutted in the shape of a palm. The vertical seal tape 5 can be inserted between both end portions of the film 1 butted in the palm shape, and the two end portions of the film 1 butted in the palm shape can be inserted between the two film end portions. The film 1 and the vertical sealing tape 5 are bonded simultaneously at both ends of the film 1 through the inserted vertical sealing tape 5, but the films 1 are heat-sealed in a non-adhered state and bonded together. The other configuration contents are the same as those of the first embodiment, and the description thereof will be omitted.
As a specific example, a vertical pillow type vertical feed continuous bag making and filling and packaging apparatus has been described. However, it can be applied to a horizontal pillow type lateral feed continuous bag making and filling and packaging apparatus.

  Various types as long as it is a vertical feed and transverse feed continuous bag making and filling device that produces a package of liquid, mucilage, or solid content to be cooked, or a content that mixes liquid or mucus with solid matter It can be used for other devices.
