Patent Name Filling and Packing Machine Patent Applicant Nippon Seiki Co., Ltd. Principal Applicant Address Niigata, Japan Inventor Tadao Toshio; Hirao Seich Application (Patent) No. 200380101699.0 Date of Application 2003.10.14 Issuance Date Approval No. 1705586 Auditing Announcement Day 2005.12.07 Manual CD-ROM D0549 main classification number B65B9/20 classification number B65B9/20 division Original application number priority item 2002.10.30 JP 315466/2002 Abstract The object of the present invention is to provide a method that does not reduce the packaging speed, and A filling machine that can supplement heat when the film is pressed by the vertical sealing mechanism and heat-sealed. In the filling and packaging machine, the film folding mechanism (14) includes an inner surface guide (19), a pair of left and right preheating modules (21), and a heater provided inside the preheating module (21) ( H) The guide guides the film (F) in the width direction of the film (F) on the inner surface side of the folded film (F); the preheating assembly is on the outer surface of the film (F) and along the film (F). In the width direction, an inclined surface (22) or an arc-shaped surface (33) is provided. The oblique surface or the circular arc surface and the inner surface guide have predetermined intervals, and the film (F) is on the upstream side in the conveying direction. The interval is more open than the interval on the downstream side. Sovereignty item 1. A filling and packaging machine in which a film is drawn from a roll of film roll wound into a roll and guided to a film folding mechanism that folds the film in half along the width of the film, and folds the film Overlapping and longitudinal sealing by a pair of opposing vertical sealing rollers provided on the longitudinal sealing mechanism, through which a cylindrical film is formed, and this cylindrical film is formed on the transverse sealing mechanism. A pair of transverse seal rolls transversely seals, a bottom is formed by the transverse seal, thereby forming a packaging bag, and the packaged object is filled in the formed bottomed cylindrical film through the bottom, and then the film is sent out, and the transverse sealing mechanism is provided. The transverse sealing roller laterally seals the position of the mouth side of the film bag to form a packaging bag, and in the filling and packaging machine which continuously packs such a packaging bag, it is characterized in that the film folding mechanism comprises: an inner surface guide, left and right A pair of preheating assemblies and a heater disposed inside the preheating assembly, the guides guiding the film along the width direction of the film on the inner surface side of the birefringent film; the preheating group The member is provided on the outer surface of the film along the width direction of the film with a mitered surface having a predetermined interval and a larger interval between the upstream side of the film in the transport direction than the interval between the downstream sides. .
