Description

  The present invention, for example, forms a packaging bag by vertically and laterally sealing a film while drawing and transporting the film from a roll of roll film, and filling the contents into the packaging bag. In addition, the present invention relates to a vertical filling and packaging apparatus that cuts the horizontal seal portion with a cutter mechanism.

Conventionally, a synthetic resin film is generally used as a packaging bag in order to fill and hermetically seal contents such as liquid and powder, for example, a base film layer made of a nylon resin film, By forming a laminate layer consisting of a sealant layer made of a low-density polyethylene resin film, or by sealing a packaging film consisting of a laminate layer obtained by joining this with an aluminum foil, etc., in three-way or four-side seals A packaging bag is formed. In order to obtain such a packaging bag, a vertical filling and packaging apparatus is known in which a film is fed out and guided from a film roll wound in a roll shape and packaged by three-side sealing or four-side sealing. In a vertical filling and wrapping apparatus that is filled and packaged with contents such as such a liquid material, for example, a film that is formed by folding and guiding a film roll that has been wound into a roll, or folded back, or A pair of vertical seal roll members sandwiching both ends of the two sheets of film, the film is vertically sealed along the longitudinal direction of the film to form a bag, and the bottom side of the film and the bag are fed while feeding the cylindrical film. A vertical filling and packaging device that continuously forms packaging bags that are vertically and horizontally sealed by a sealing mechanism that horizontally seals the portion on the mouth side with a transverse seal member of a transverse seal roll that forms a pair along the width direction of the film. It has been known. At this time, the packaging bags that are continuously fed out are perforated at the lateral seal portion of the packaging bag by the cutter mechanism on the downstream side of the horizontal sealing mechanism, or the entire packaging bag is separated and transported separately. I am doing so. (For example, see Patent Document 1.)

The position of the substantially central portion of the lateral seal portion sealed by the sealing mechanism is divided along the width direction of the film. At this time, since the horizontal seal portion is heated by the horizontal seal member, the sealant layer on the inner surface side of the film is not sufficiently cooled and can be cut by the cutting blade by the cutter mechanism before the adhesive strength is secured. is there. For this reason, when cutting the packaging bag, a sealant layer that is not sufficiently cooled adheres to the cutting edge of the cutting blade of the cutter mechanism, which may result in poor cutting of the cutter mechanism and may prevent the film from being cut well. . In addition, this type of vertical filling and packaging apparatus is desired to be able to manufacture a packaging bag at a high speed, and the contents filling operation, the vertical and horizontal sealing operations, and the packaging bag are increased while increasing the film feeding speed.

  During the cutting operation of the packaging bag P, the packaging bag P is cut by the cutter mechanism 7 in a state in which the sealant layer at the lateral seal FS location of the packaging bag P is cooled in advance to ensure the seal strength at the lateral seal FS location. Therefore, the sealant layer can be prevented from adhering to the cutting blade 7A of the cutter mechanism 7 in substantially the same manner as in the above-described embodiment. In addition, the packaging operation of the packaging bag P is performed while increasing the operating rate of the vertical filling and packaging apparatus by adopting box motion drive (vertical movement of the cutter mechanism 7 and the air injection nozzle mechanism 8) in accordance with the feeding of the film F. There is an effect that can be performed. That is, by performing the process of cooling the horizontal seal FS location in advance by the air injection nozzle mechanism 8 and the cutting process of the horizontal seal FS location by the cutter mechanism 7 while moving downward according to the feeding speed of the film F.

It is set so that air is blown out in synchronization with the passage timing of the lateral seal portion of the film during the cutting operation, and the time of air blow is determined by the material and thickness of the film F, the feeding speed of the film F, and the heating of the seal portion. What is necessary is just to provide so that adjustment is possible via the control means 12 according to specification conditions, such as temperature.

  In each embodiment, when the operation switch 11B including the operation start / operation stop switch for operating the vertical filling and packaging apparatus is turned on, the air injection nozzle mechanism 8 and the gas pressurizing means 9 are operated. The solenoid valve 10 for supplying and shutting off air as pressurized gas is operated to be opened, but the main power switch 11A for turning on / off the vertical filling and packaging apparatus may be turned on in some cases. The air injection nozzle mechanism 8 may be configured to always operate by operating.
