Title: Innovations by Shuichi Kojima
Introduction
Shuichi Kojima is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of weaving technology, holding a total of 9 patents. His work focuses on enhancing the efficiency and functionality of looms, particularly through innovative weft picking systems.
Latest Patents
One of his latest patents is a weft picking system for a fluid jet loom that includes a roller type. This system is designed for an air jet loom and is equipped with a microcomputer as a controller. The weft picking system features a weft traction device that includes a pair of rollers, one of which is driven by an inverter motor. The weft yarn is fed from a measuring and storing device and is drawn toward a weft posture regulating nozzle. This nozzle projects the weft yarn into the shed of warp yarns while regulating its posture, aided by an air jet and additional air ejection from sub-nozzles. The rollers continuously rotate during the loom's operation, and a change-over device allows for seamless transitions between different states of the weft yarn.
Another notable patent is a weft supply changing and threading apparatus. This yarn supply system includes a mechanism for replacing a used yarn supply member with a new one when the weft yarn is depleted or broken. The new yarn supply member is delivered to the changing apparatus by a self-propelled carriage and is then carried to a supply position. The weft yarn is threaded into a weft winding arm under the influence of an air stream, facilitating efficient weft picking.
