DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filling method in which a package to be packaged such as a liquid, a powder or a viscous substance is hermetically sealed by vertically or horizontally sealing a three- or four-sided seal of a continuously transferred packaging film. The present invention relates to a packaging machine, and more particularly to a packaging machine for removing ears (chips), which are unnecessary portions of a vertical seal portion heat-sealed by a vertical sealing mechanism of the packaging machine.

[0002]

2. Description of the Related Art Conventionally, as a hermetically sealed packaging bag filled with an object to be packaged, such as a liquid, powder or viscous substance, a synthetic resin film or an aluminum foil or the like is generally bonded. A packaging bag is formed by vertically or horizontally sealing a packaging film made of a packaging material such as a laminated product three- or four-sidedly.

[0003] Accordingly, as a filling and packaging machine for packaging such a package bag by three- or four-side seal sealing, for example, JP-A-1-153410, JP-A-2-32929 or JP-A-2-32929. 61-6
As shown in Japanese Patent Publication No. 9521, a pair of holding frames are provided on the side of the machine base of the filling and packaging machine. A film guide portion and a film folding portion are disposed on the upper portion of the machine base, and a vertical seal portion, a horizontal seal portion, and a cutter portion are provided on the front portion of the machine frame from the upper side. The film is folded into two along the longitudinal direction by the film folded portion, the film is longitudinally sealed by the heated vertical seal portion, and then the heated horizontal seal portion is formed by the heated horizontal seal portion. The film is laterally sealed in the horizontal direction, and the horizontal seal forms a bottom portion that becomes a packaging bag. Is filled, the film is further fed, and the bag mouth side of the film is horizontally sealed again by the horizontal sealing portion to seal the packaged material, and then the intermediate portion of the horizontal sealing point is cut by the cutter portion. There is known an apparatus in which a packaging bag is obtained by performing the method.

[0004]

By the way, in the above-mentioned conventional filling and packaging machine, the film is fed out while being sealed by the vertical seal portion and the horizontal seal portion. However, the rotation speed of these seal portions is increased. While film seal packaging can be speeded up, the film can be sent unevenly due to irregularities in the winding of the film wound around the roll or fluctuations in the tension of the film drawn from the film winding. Therefore, if the film is fed while the folding position by the film folding section is biased, the vertical sealing position will fluctuate from a predetermined position, and the sealing interval of the side edge of the film by the vertical sealing section will vary, or the packaging film Or the edges of the vertical seals may be uneven, Because it can Mau, sometimes to maintain a favorable package form by removing the ear portion of the vertical seal portion.

When an ear cutting mechanism for removing the ears of the seal portion is installed in the mechanical device of the filling and packaging machine to cut off the unnecessary ears, the ears, which are the chips, are added to the product packaging bag. They may adhere due to the action of static electricity, and this may take a lot of time to remove the ears that become chips.

[0006] Also, a packaged object W to be filled in the packaging bag P.
However, in the case of a favorite item such as a sauce, soup or soy sauce, there is a risk that the chips having the chips attached to the packaging bag may be transferred to the food side. There is a tendency to avoid using packaging machines with removal devices for packaging products such as food.
