  The present invention is, for example, a four-sided three-dimensional package in which packages to be packaged such as confectionery, processed foods, and agricultural products are accommodated, and uses a single packaging sheet, a so-called single packaging sheet. A four-sided three-dimensional package composed of a four-dimensional three-dimensional package manufactured using a package manufacturing apparatus and a single packaging sheet, a so-called single packaging sheet, is obtained using a four-dimensional three-dimensional package manufacturing apparatus for a single packaging sheet. The present invention relates to an apparatus for manufacturing a four-sided three-dimensional package.

  In general, a so-called vertical packaging sheet packaging apparatus (vertical pillow packaging apparatus) is known as a machine for manufacturing a package that contains packages such as confectionery, processed food, and agricultural products. This vertical pillow wrapping device winds a single wrapping sheet (film), which is a single wrapping sheet (film), around a cylinder, welds the seam in a vertical direction with a vertical sealer, and lowers the lower end of the packaging sheet into a horizontal sealer. Weld with. In a state where the packaging sheet is welded, an article to be packaged is put into the cylinder from above the cylinder, and the article to be packaged is accommodated in the packaging sheet. After the packaged material is accommodated in the package sheet, the package sheet is pulled downward by a predetermined size by the sheet pulling means, and a predetermined portion of the package sheet is welded in the horizontal direction by a horizontal sealer to enclose the packaged product.

  As described above, in a general vertical pillow wrapping apparatus, a film as a single wrapping sheet is fed out, and both ends (seal surfaces) of the wrapping sheet are aligned with a former to form a cylindrical seal. Next, the packaging sheet is pulled up one pitch at a time using soccer, paper drawing and horizontal sealer, and horizontal sealing is performed. At the same time as pulling down the packaging sheet, the packaged object weighed from the hopper falls and is cut at the same time as the head is sealed. Actually, bottom / head sealing and cutting are performed simultaneously. And the package which enclosed the to-be-packaged object is discharged | emitted with a conveyor.

  The vertical pillow wrapping apparatus is a pillow wrapping apparatus in which the completed bag form is a pillow (pillow), and the wrapping sheet runs from top to bottom. There is also known a horizontal packaging sheet packaging apparatus (horizontal pillow packaging apparatus) in which the completed bag form is a pillow (pillow) and the sheet runs in the lateral direction. In any pillow wrapping device, a back seal (center seal) is first made to form a tube (tube shape), and then a side seal (cut seal) is placed while containing packages such as confectionery, processed foods, and agricultural products. It has a process.

  As a vertical pillow packaging device, as shown in Patent Document 1, when welding a packaging sheet with a horizontal sealer, the folding plate is inserted every other time, and a crease is formed on both sides of one packaging sheet (single packaging sheet). The portions welded in the state of forming and the portions welded without forming folds on both sides of the packaging sheet are alternately formed. In this vertical pillow wrapping apparatus, a package body having a fold line on one side and no fold line on the other side is continuously manufactured.

  On the other hand, a four-dimensional three-dimensional package shown in Patent Document 2 proposed by the inventor is known. This four-sided three-dimensional package is a four-dimensional three-dimensional package composed of a single packaging sheet. Closed by a pair of opposing left side seam (seam, heat seal) and right side seam (seam, heat seal), and closed by an upper side seam (seam, heat seal) which is one of the other two opposite sides ing.

And when taking out the vegetables etc. which are to-be-packaged objects, the left side seam and right side seam which oppose are torn. Since the right-side seam and the left-side seam arranged to face each other can be torn, the four-sided three-dimensional package can be easily opened.

  In this way, in the four-sided three-dimensional package composed of this one packaging sheet, the most part or the whole of the opposing left-side seam and right-side seam required when forming the bag body is torn. The package can be opened easily. In addition, when opening a package such as vegetables, most or all of the left and right seams facing each other are artificially torn, so that the four-sided three-dimensional package extends into a boat shape. The resulting boat-shaped package is a four-sided three-dimensional package that functions as a container for objects such as vegetables.

  The four-sided three-dimensional package is a four-sided three-dimensional package that produces a four-dimensional three-dimensional package from a flat bag. Once the bag is created, the bag is opened and the package is accommodated, and the bag is closed. It is a three-dimensional package, and the process and process of housing the package in the bag are complicated.

  Further, a four-dimensional three-dimensional package shown in Patent Document 3 proposed by the inventor is known. This four-sided three-dimensional package is a four-dimensional three-dimensional package that is closed with an upper side seam (seam, heat seal) in a state in which an object to be packaged is housed in a cylindrical bag closed with a lower side seam (seam, heat seal).
