A vertical bag-making/filling/packaging machine () comprises: a film supply portion (); a film engaging portion () which is engaged with a film (F); a vertical seal portion () which makes the film (F) into a tubular shape; a film conveying portion (); a film clamp () which holds the film (F) at the film engaging portion (); a film tension releasing portion () which loosens the film (F); a filling portion () which inputs the content (X); a weighing portion () which weighs the content (X); a lateral sealing portion () which makes the film (F) into a bag body (G); and a cutter which cuts off the bag body (G).

Vertical bag-making/filling/packaging machine, manufacturing method of film packaging bag with content

There is provided a packaging apparatus including a mechanism for joining a film from a film roll and a film from another film roll to each other. The packaging apparatus is capable of preventing a joint of the films from suffering a thermal sealing failure thereby increasing production efficiency. Package apparatus () includes film supply mechanism (A) for joining and supplying films (A,B) and packaging mechanism (C) for producing package bags from the film. Film accumulator (B) for guiding and holding the film in a meandering fashion is disposed between film supply mechanism (A) and packaging mechanism (C). Some of accumulating rollers () of film accumulator (B) are movable to a predetermined position depending on the size of package bags to be manufactured. The length of the film from a position in which the films are joined to each other to a position in which the film is horizontally sealed is changed to prevent the joint between the films from being placed in the position in which the film is horizontally sealed.

Packaging apparatus

A vertical-type filling and packaging machine for filling and packaging a filling material in a tubular film of resin has a pair of squeezing rollers rotatably disposed one on each side of the tubular film filled with a filling material. The squeezing rollers press against the tubular film to clamp and feed the tubular film downwardly and create an unfilled region in the tubular film. A heat sealing mechanism which is disposed downwardly of the squeezing rollers for heat-sealing and severing the unfilled region has a heater bar for heat-sealing the unfilled region and a cooling bar for cooling the portion which has been heat-sealed by the heater bar. The heater bar and the cooling bar are successively pressable against a portion of the unfilled region while the tubular film is being held at rest. A cutting device, which may be an independent cutting blade or a triangular protrusion on the heater bar, severs the heat-sealed portion, thereby producing a sacked product. A plurality of film support members are disposed downwardly of the heat-sealing mechanism for gripping and holding a lower end of the unfilled region from the time the unfilled region is heat-sealed until the unfilled region is severed by the heat sealing mechanism.
