Definitions

  • the present invention relates to a sheet folding apparatus provided with a bending promoting portion in advance.
  • a sheet as a material is bent. In that case, unless it is special, it is usually done on an automated line. For this reason, it is necessary to ensure the repeat position accuracy of the bent part and to supplement the equipment to reduce the return after bending, to reduce the variation in bending angle and to facilitate folding. Further, in order to facilitate the folding of the sheet itself at a certain position, a portion for promoting the bending process (hereinafter referred to as a bending promoting portion) is provided in the portion to be folded. For example, a portion (hereinafter also referred to as ascending line) provided with a dent or opening in a rising line shape along the folding line of the sheet is applied.
  • Such sheets include (1) a layer with a function (hereinafter also referred to as a functional unit) formed by means such as printing, as in an electronic circuit or a decorative painting, and a material case ( 2) Some are made only of sheet material. Especially in the former case, it is important to bend and efficiently fold it without adversely affecting the functional parts formed on the sheet.

  • Patent Document 1 Japanese Patent Application Laid-Open No. 7-186307 introduces an example in which a long sheet is fed and folded with a former. In this example, meandering of the sheet is suppressed without providing a meandering correction mechanism to ensure the repeatability of the folding position. Especially in the case of a narrow sheet, the resistance to adhesion to the former wall due to the material is large on both sides of the folded part. Therefore, an unbalance of the bending resistance occurs on both sides, and it tends to shift to the side with the same resistance.
  • Patent Document 2 introduces an example of folding a large amount of paper after folding and folding a paper or resin box! The sheet is sandwiched between the belts and moved horizontally, while the bent part is held down with a pinching belt or roller to avoid bending back. In that state, an adhesive layer is applied to the sheet, and the sheet is folded with a roller and a twist belt while being gradually pressed, and then the sheet is folded and bonded. This is an example of equipment that is a compact collection of these operations. Furthermore, Japanese Patent Application Laid-Open No.

  • Patent Document 4 introduces a resin sheet that is corrugated in the plane and has a bending and rising line having a certain depth in the thickness direction. This makes it easier to bend and makes it difficult to cause propagation damage in the ascending direction due to bending that is relatively hard V and occurs easily with resin.

  • Patent Document 1 The means disclosed in Japanese Patent Laid-Open No. 7-186307 (Patent Document 1) is mainly relatively narrow. When folding a long sheet, the crease is positioned while correcting the transport route.
