A vertical bag-making/filling/packaging machine includes: a top folding portion which forms a first fold by folding one of sides of a band-shaped film into a Z shape; a bottom folding portion which folds a center of the film so that side edges of the film face each other; a first pleat guide which pulls a first pleat of the first fold upright; a spout portion-forming portion which forms a spout portion between the side edges of the film; and a second pleat seal portion which forms a second pleat by heat-welding the side edges of the film together so as to make the film into a tube shape.

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

A vertical bag-making/filling/packaging machine () includes: a top folding portion () which forms a first fold (F) by folding a side of a band-shaped film (F) into a Z-shape; a bottom folding portion () which forms a second fold (F) by folding a center of the film (F) into an M-shape; a top seal portion () which forms a top gusset (G) and a spout portion (G) protruding from the top gusset (G) by heat-welding the first fold (F) and side edges (Eand E) of the film (F) so as to make the film (F) into a tube shape; and a bottom-seal portion () which forms a bottom gusset (G) by heat-welding the second fold (F).

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

A vertical bag-making/filling/packaging machine () comprises: a film supplying portion () which lets out a film (F) from a roll (Fr); a bag-making guide () which folds the film (F) into a tubular shape and changes a conveying direction downward; a vertical sealing portion () which thermally seals side edges of the film (F) to each other in an up-down direction so as to make the film into a tubular shape; a film conveying portion () which conveys the film (F) downward; a filling portion () which loads a content (X) into an interior of the film (F); a lateral sealing portion () which thermally seals the film (F) in a left-right direction so as to make a bag body; a square-bottom sealing portion () which expands a bottom of the bag body to a rectangular shape from an inside and then thermally seals the bottom to form a rectangular bottom surface; and a cutter () which cuts off the bag body from the film (F).

A vertical filling and packaging machine of the present invention includes tension devices () that are disposed near positions of ironing rollers () and that pull both sides of cylindrical film () laterally outward. Tension devices () pull both sides of cylindrical film () laterally outward to flatten a portion of cylindrical film () before the pair of ironing rollers () sandwiches the portion of cylindrical film (), wherein the content has been injected into the cylindrical film (). As a result, when lateral seal part () is formed on cylindrical film () by lateral seal device (), lateral seal part () is not easily wrinkled.
