Description

  The present invention belongs to the technical field of an automatic packaging machine that automatically fills and wraps a material to be packaged (contents) using a packaging film (packaging material). The present invention relates to a film forming adjustment mechanism of a palm-fitting method in an automatic packaging machine that forms a stick packaging bag by forming into a cylindrical shape.

  2. Description of the Related Art Conventionally, there is a vertical multi-row automatic packaging machine configured so that a plurality of stick-type packaging bags can be continuously sealed and formed at a time. This is because each of the packaging films cut into a plurality of pieces is wound around each of the filling pipes configured in a multi-row system and formed into a cylindrical shape, and then the both ends of the wound packaging film are aligned with each other. A vertical heat sealer is used to form a cylindrical packaging film, and then a horizontal heat sealer is applied to a prescribed position of the cylindrical packaging film to form a bag-shaped packaging film.

  This vertical multi-row automatic packaging machine puts the material to be packaged (contents) through the filling pipe into the finished bag-shaped packaging film, and then seals the filling port of the packaging bag by lateral sealing. Then, the vicinity of the center of the sealed horizontal seal is separated using a cutter device, and finally the stick-shaped packaging bags in the individual packaging form are multi-row and continuously sealed. Yes. An example of such a vertical multi-row automatic packaging machine is disclosed in Patent Document 1.

  The above vertical heat sealer is similar to the envelope pasting method in which both ends of the packaging film wound around each filling pipe and formed into a cylindrical shape are overlapped on the filling pipe, and then the seal fitting is pressed and welded. There is a palm-pasting method in which both end portions of the packaging film are pulled out at right angles to the filling pipe and then the overlapping portions are sandwiched and welded. The two vertical sealing methods are selected in consideration of factors such as the material of the packaging film, the type of contents filled in the packaging bag, and the appearance of the finished packaging bag.

When vertical sealing is applied to a packaging film that uses aluminum foil as the base film by the envelope sticking method, the seal fitting that performs this vertical sealing should strike the filling pipe wrapped with the packaging film. Because of the pressing, a cracking accident may occur in the aluminum foil, and such a packaging film usually employs a vertical seal with a palm-and-stick method.
Japanese Patent Laid-Open No. 9-272511
