Abstract

A packaging apparatus includes a conveying unit that conveys a continuous film in a first direction with an article placed on a first portion of the film, and folds back in a second direction opposite to the first direction a second portion of the film ahead of the first portion with respect to the first direction, sealing parts that seal the first portion and the second portion to form a bag body containing the article, and a cutter that cuts the film.

1 . A packaging apparatus comprising:
 a packaging material conveyor that conveys a continuous band-shaped packaging material in a first direction with an article placed on a first portion of the packaging material, and folds back in a second direction opposite to the first direction a second portion of the packaging material ahead of the first portion with respect to the first direction;   a sealer that seals the first portion and the second portion to form a bag body containing the article; and   a cutter that cuts the band-shaped packaging material.   
     
     
         2 . The packaging apparatus according to  claim 1 , wherein
 the packaging material conveyor puts the second portion folded back in the second direction over the article from above the article.   
     
     
         3 . The packaging apparatus according to  claim 1 , further comprising:
 a joiner that joins the band-shaped packaging material separated due to cutting by the cutter.   
     
     
         4 . The packaging apparatus according to  claim 3 , further comprising:
 a roller that rolls up a predetermined amount of the band-shaped packaging material that has been joined by the joiner, so as to collect a joined portion by the joiner of the band-shaped packaging material.   
     
     
         5 . The packaging apparatus according to  claim 1 , wherein
 the packaging material conveyor includes a holder that moves along a predetermined path while holding a tip portion of the band-shaped packaging material so as to fold back the second portion.   
     
     
         6 . The packaging apparatus according to  claim 1 , further comprising:
 a setter that sets an amount of the packaging material to be conveyed in the first direction by the packaging material conveyor in accordance with a dimension of the bag body along a length of the band-shaped packaging material.   
     
     
         7 . The packaging apparatus according to  claim 1 , further comprising:
 a controller that makes a level of sealing of the first portion and the second portion by the sealer and a level of approximately the middle of the article along its thickness agree with each other.   
     
     
         8 . The packaging apparatus according to  claim 1 , further comprising:
 a placement device for placement of the article on the band-shaped packaging material; and   a display that displays a position and/or a timing for placement of the article on the band-shaped packaging material at the placement device.   
     
     
         9 . The packaging apparatus according to  claim 1 , further comprising:
 a puller that pulls part of the band-shaped packaging material constituting the bag body.   
     
     
         10 . The packaging apparatus according to  claim 9 , wherein
 part of the band-shaped packaging material pulled by the puller includes the second portion to be used in subsequent packaging.   
     
     
         11 . The packaging apparatus according to  claim 1 , further comprising:
 a position definer that defines a position at which the band-shaped packaging material is folded.   
     
     
         12 . The packaging apparatus according to  claim 1 , further comprising:
 a weigher that weighs the article.   
     
     
         13 . The packaging apparatus according to  claim 1 , further comprising:
 a printer that prints information on the article on a label.
