The present invention relates to an automatic packaging machine.

  DESCRIPTION OF RELATED ART Conventionally, the powdery or granular to-be-packaged goods, such as a chemical | medical agent, a luxury product, a seasoning, and another foodstuff, are sealed and packaged and provided in the package (product) in which one or two or more continued. As an automatic packaging machine for producing such a packaged body, a long packaging material is folded in two along the longitudinal direction, and the packaging is supplied into the bottomed packaging material. At the lower position of the chute, a sealing device for sealing and packaging the packaging material supplied from the molding chute by vertically sealing and transversely sealing the packaging material folded in two at the lower position of the molding chute A configuration comprising a cutter device or the like that obtains a package body in which one or two or more pieces are continuous by cutting a packaging material in which a packaged object is hermetically packaged at predetermined intervals is known. .

  In the above-described conventional automatic packaging machine, a long film-shaped packaging material made of polyethylene, polyvinyl chloride or other thermoplastic resin is folded in half along the longitudinal direction with a molding chute, and then a sealing device is constructed. A pair of horizontal seals of the horizontal seal device that also constitutes the seal device after vertically sealing both side edges of the packaging material folded in half with a pair of vertical seal heat welding rolls of the vertical seal device to form a tube shape A tube-shaped packaging material is laterally sealed for each package (for one bag) by a heat welding roll, and the packaged material supplied from the molding chute is hermetically packaged. And the packaging material in which the packaged goods are packaged every one bag in this way is cut at a predetermined distance by the cutter device, so that one package or a package in which two or more are continuous is obtained. can get.

  The forming chute that constitutes the automatic packaging machine is a convex surface that is wide at the upper end and gradually narrows toward the lower end in order to fold the unfolded packaging material in the longitudinal direction. A guide member as a member is provided. Since the packaging material is continuously passed along the surface of the guide member, the packaging material is folded in a U shape in a horizontal sectional view and sent to the sealing device and the cutter device.
