Aseptic filling packaging machine and aseptic filling packaging method

摘要

Provided is an aseptic filling packaging machine that includes film feeder (1), plug feeder (2), welding devices (22, and 55), sterilizer (3), and filling packaging device (5). Film feeder (1) feeds strip film (8). Plug feeder (2) feeds plug (7) to a predetermined position of fed film (8). Primary welding mechanism (22), which serves as a welding device, temporarily welds plug (7) to the predetermined position of film (8). Sterilizer (3) immerses film 8 having plug (7), which has been fed from film feeder (1), in a sterile liquid. While forming film 8 having plug (7), which has been fed from sterilizer (3), into a bag shape, filling packaging device (5) fills the formed film packaging body having the plug with content to seal it. In filling packaging device (5), secondary welding mechanism (55) that serves as a welding device completely welds plug (7) to film (8).

主权项

1. An aseptic filling packaging machine comprising:
a film feeder that feeds a strip film; a plug feeder that feeds a plug to a predetermined position of the fed film; a welding device that welds the plug to the predetermined position of the film; a sterilizer that immerses the film having the plug, and which has been sent from the film feeder side, in a sterile liquid; and a filling packaging device that forms the film having the plug, and which has been sent from the sterilizer side, into a bag shape, and fills a formed film packaging body having the plug with content to seal the film packaging body, wherein the welding device comprises a primary welding mechanism for tack-welding the plug at a surface facing the film to a surface of the film prior to forming into the bag shape; and a secondary welding mechanism for welding the entire surface of the plug facing the film to the surface of the film, wherein the primary welding mechanism is located upstream of the sterilizer in a feeding direction of the film and oppositely to the plug fed from the plug feeder interposing the film; and the secondary welding mechanism is located downstream of the sterilizer in the feeding direction of the film and between a film forming unit of the filling packaging device and a content filling port.
