Bag-making and packaging machine
First Claim
1. A bag-making and packaging machine comprising:
- a bag-making apparatus for manufacturing bags by performing a bag-making operation while unwrapping a film from a film roll whose axial center is disposed in a horizontal attitude and feeding said film in a direction of length thereof, said bag-making operation including;
folding said film in two and overlapping said film by a forming apparatus,sealing said film at locations that correspond to bag bottom portions and side portions by a sealing apparatus, andseparating bags by cutting with a cutting apparatus;
a bag-filling packaging apparatus which grips both side edges of said bags by means of grippers thus suspending said bags, intermittently moves said suspended bags along an annular path, and performs packaging operations including filling of said bags with contents and sealing of mouths of said bags, at respective stopping positions; and
a bag transfer apparatus which receives said bags at a receiving position at a final end of said bag-making apparatus, conveys said bags to a transfer position, and transfers said bags to said grippers of said bag-filling packaging apparatus;
whereinsaid bag-making apparatus is a horizontal type bag-making apparatus in whichsaid film folding in two and overlapping said film is performed in a horizontal attitude by said forming apparatus, and bag-making operations are performed on said film while being fed in said horizontal attitude,positions corresponding to lower ends of folded and overlapped film bags are set in same positions regardless of a bag length, andsaid forming and sealing apparatuses of said bag-making apparatus are disposed with reference to said positions; and
said bag fluster apparatus receives bags in a horizontal attitude, stands said bags upright and transfers said bags to said grippers of said bag-filling packaging apparatus.

Abstract
A bag-making and packaging machine including a bag-making apparatus 1, a bag-filling (packaging) apparatus 2, and a bag transfer apparatus. The bag-making apparatus 1 of a bag-making and packaging machine, while releasing a film F from a film roll disposed in the horizontal direction and feeding the film lengthwise, folds and overlaps the film in two in a horizontal attitude, performs sealing in locations corresponding to the bag bottom portions and side portions of the film in the horizontal attitude, and separates bags by cutting. The line corresponding to the bag bottom ends of the folded and overlapped film F (this position indicated by S) is set in the same position regardless of the bag length, and the respective apparatuses such as the forming apparatus 5, sealing apparatuses 8, 9 and 11, and cutting apparatus 14, etc. are disposed with reference to this position.
