った。According to the above-described method of increasing the sealing temperature of the heat seal bar to strengthen the horizontal seal, the packaging speed does not need to be reduced. (Securing within the intermittent stop time) is proportionally shorter, which is effective. However, in order to prevent waste paper, when the operation is temporarily stopped and restarted, the heat seal bar sealing temperature may become abnormally high and the web may be welded to the heat seal bar. There is a limit to increasing the temperature, and it is not possible to cope with an increase in the packaging speed (for example, a packaging speed of 100 bags per minute or more). Also,
When the sealing temperature is increased and the sealing time is shortened, the heat-soluble inner layer films constituting the web do not sufficiently adhere to each other and the adhesion to the outer layer film is peeled off, resulting in poor sealing, and the heat constituting the web. It damages the plastic outer layer film. Further, according to the above-described method of extending the sealing time to strengthen the horizontal seal, it was impossible to cope with an increase in packaging speed at all.

In the vertical bag making / filling / packing method, a continuous web F is hung on a bag making machine 1 and is folded up into a cylindrical shape so as to wrap the cylindrical body 2 passed through the inside of the bag making machine 1, and the side of the cylindrical body 2 is taken up. The edges f of the webs on both sides are aligned with each other in a palm-shape or envelope-attached manner, and are hung below the horizontal seal / cut position below the cylindrical body 2 to start packaging, and when the web feed is intermittently stopped, the above-mentioned two sides are closed. The web edge f is vertically sealed by the vertical sealing device 3 to form the packaging tube H, and the horizontal sealing / cutting device 4 seals the packaging tube H with two horizontal stripes and cuts between the seals.
Further, the package F is dropped into the cylindrical body 2 which horizontally seals and cuts the upper side and the lower side of the filled package F of the packaging section H, and the package F contained in the packaging tube H is dropped. Is received by the shutter 5 attached to the horizontal seal / cutting device 4, the seal bars of the vertical seal device 3 and the horizontal seal / cut device 4 are separated from the web, and then the web F is moved downward by the web feeding device 6. The package is transported by the length of one bag, intermittently stopped again, and again vertically sealed and horizontally sealed and cut, so that the upper and lower portions of the packaged material F filled in the packaging tube H of the packaging tube H are removed. The side is horizontally sealed and cut to produce a packaged bag.

なりウエブ内面同士のシール溶着が強く行われる。In the method for reinforcing a horizontal seal according to the embodiment of the present invention, in the above vertical bag making and filling method, the position of the web F upstream of the bag making machine 1 can be adjusted to a position for transferring the web F into a horizontal plane. A pair of upper and lower preheating seal bars 7a and 7b, which can be opened and closed, of a preheating sealing device 7 provided in the above-mentioned position are aligned by driving a motor or operating a handle prior to packaging. This positioning is performed by moving the preheating position by the preheating seal bars 7a and 7b to a position corresponding to a multiple of the bag length following the upstream direction from the horizontal sealing / cutting position of the web F. This is to be matched with the horizontal double-row seal position of No. 4. Then, when the web F for performing the horizontal sealing and cutting is intermittently stopped, the preheating seal bar 7 is used.
The webs F are sandwiched by closing the webs a and 7b, and the web F is preheated in a band shape in the width direction. The preheating temperature is set to be about 10 to 20 degrees lower than the sealing temperature by the horizontal sealing and cutting device 4. The web F is a laminate of a heat-soluble film (for example, a polyethylene film) and a thermoplastic film. The upper surface of the web F at the preheating position is a heat-soluble film, and the lower surface is a thermoplastic film. Therefore, the preheating temperature of the upper preheating seal bar 7a is set to a temperature several degrees lower than the melting temperature of the heat-soluble film of the upper layer of the web F, and the preheating temperature of the lower preheating seal bar 7b is set to the It is preferable that the melting temperature of the heat-soluble film of the upper surface layer is substantially the same as the melting temperature. The pre-heated strip-shaped portion is sealed by the horizontal sealing and cutting device 4 in two horizontal rows before it is cooled. Therefore, the sealing temperature at the horizontal double-row seal position is increased, and the seal welding between the inner surfaces of the web is performed strongly.

Therefore, the sealing strength of the horizontal seal can be enhanced without lowering the packaging speed, and it is possible to sufficiently cope with an increase in the packaging speed.
