Description

  The present invention relates to a sheet manufacturing apparatus for manufacturing a sheet by die-cutting a base material using a rotary die-cut portion comprising a die-cut roll having a cutting blade provided on a peripheral surface and a die-cut receiving roll, and in particular, a base material in a circular shape or the like The present invention relates to a sheet manufacturing apparatus for manufacturing a sheet in which a punched portion is formed by a die cut roll provided with a punching cutting blade provided on a peripheral surface.

  In a die-cut roll in which a punching cutting blade for forming a punching portion such as a circle on a base material is provided on the peripheral surface, a hollow portion is provided inside the die-cut roll, and a hollow portion is provided in a region surrounded by the punching cutting blade. By providing a discharge path that communicates, punch punch punched out from the base material is bitten into the cutting blade for cutting, and is sequentially inserted into the discharge path, and the punch residue pushed out from the discharge path to the hollow portion is collected, thereby ensuring the punch residue. What was comprised so that it might collect | recover is employ | adopted (for example, refer patent document 1).

  However, in the prior art, when the punched cutting blade is used to form a punched portion on a base material having a thickness of less than 200 μm, the punched punch scraped into the punching cutting blade becomes shallow, and the punch waste is 100% in the discharge path. There is a problem that it is difficult to insert the punched punch, and the punch scraps that have fallen into the cutting blade for punching are mixed into the product.

  Moreover, the fall of the punch residue tends to occur more frequently as the punch residue is larger. For example, when a 2φ (circular with a diameter of 2 mm) punch scrap and a 6φ (circular with a diameter of 6 mm) punch are compared, circular cutting is started by a die-cut roll, and the punch center portion (diameter 1 mm or diameter 3 mm) is cut. When inserted into the punching blade of 2φ, the base material is thin, and even if the biting into the cutting blade for punching is shallow, the cutting ends with the remaining 1 mm of rotational movement. Since the punch scrap requires the remaining 3 mm of rotational movement, if the bite into the punching cutting blade is shallow, the punch scrap may be pulled out in the traveling direction (rotation direction) of the die cut roll and dropped.
