Kiyoshi Hirosawa is a notable inventor based in Chikusei, Japan. He has made significant contributions to the field of bar feeding technology, holding a total of 2 patents. His innovative designs have streamlined processes in manufacturing, particularly in the machining of bars.

Latest Patents

Hirosawa's latest patents include a bar feeder that is capable of reliably loading a bar onto a guide rail with a simplified structure. This bar feeder comprises a stock rack, a guide rail for guiding a bar to a bar machining apparatus, and a bar supply mechanism for taking bars one by one out of the stock rack and supplying the taken-out bar onto the guide rail. The design features a lifting member that lifts the downstreammost bar on the stack rack, a bar receiving member that supplies the bar onto the guide rail, and a stopper member that holds the second-downstreammost bar for subsequent supply. The common moving device that drives both the lifting and receiving members reduces the number of components, achieving structural simplification.

Another patent involves a bar feeder that includes a swing member designed to be swingably moved by a rotation shaft located above a guide rail. In normal mode, the swing member is kept in a standby position near the upper position, extending across and over the guide rail up to a bar rack. The swing member rotates to a lower position when not in use, allowing for easy loading and unloading of bars from the guide rail.
