Japanese paper yarn manufacturing device and japanese paper yarn manufacturing method

Abstract

A Japanese paper yarn manufacturing device according to the present invention that provides a method for mass-production of inexpensive Japanese paper yarns by saving labor includes a slitter that slits a Japanese paper sheet fed out from a Japanese paper roll into a plurality of Japanese paper tapes each having a narrow width in a feeding direction, and a distributing section that distributes the plurality of slit Japanese paper tapes. An air flow section feeds air into a plurality of the tubes of the distributing section, so that the distributed Japanese paper tapes are sent in a floating manner to a plurality of yarn processing device units.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to Japanese Patent Application No. 2019-017947, filed Feb. 4, 2019. The contents of that application are incorporated by reference herein in their entirety.BACKGROUNDTechnical Field[0002]The present invention relates to a novel Japanese paper yarn manufacturing device and a Japanese paper yarn manufacturing method.Background Art[0003]In recent years, many products using a Japanese paper yarn that make use of the characteristics of Japanese paper have been provided. A Japanese paper yarn is formed by slitting a sheet of Japanese paper to Japanese paper tapes with widths of about several millimeters and twisting the slit Japanese paper tapes into yarns. Industrially, a sheet of Japanese paper is slit into a plurality of Japanese paper tapes having widths of various sizes by a slitter, and each of the slit Japanese paper tapes is wound into a cheese to obtain a wound body. From these wound bodies, the wound b...

AI Technical Summary

Benefits of technology

The present invention provides a new Japanese paper yarn manufacturing device and method that saves labor and energy and produces inexpensive Japanese paper yarns through continuous supplication of Japanese paper tapes. The device automatically processes the tapes into yarns without stopping and even if several tapes or yarns break, the manufacturing process continues without human operator intervention. The device uses air to carry the paper tape without contact with the inner surface of the tube, reducing friction and breakage. The speed of air flow matches or exceeds the speed of the paper tape feeding, ensuring smooth and secure processing.

Problems solved by technology

However, when each of Japanese paper tapes is wound into a cheese, when a wound body of the Japanese paper tape is stored, and furthermore, when each of Japanese paper tapes is unwound from the wound body to manufacture a yarn, winding of the Japanese paper tape may collapse.

The winding collapse has caused not only material loss, but also yarn breakage and poorer productivity.

As a result, the Japanese paper tape is often torn when the yarn is produced with a twisting machine or a covering machine, which has been a cause of poor productivity.

For this reason, wastes in labor and time loss are large, and have been the bottlenecks in cost reduction.
