Title: Ryuji Yamakawa: Innovator in Electronic Component Handling

Introduction

Ryuji Yamakawa is a notable inventor based in Nagaokakyo, Japan. He has made significant contributions to the field of electronic component handling, holding 2 patents that showcase his innovative approach to technology.

Latest Patents

Yamakawa's latest patents include a unique conveyor equipment design. This invention features retainer grooves formed widthwise at a constant pitch on the external surface of a timing belt. These grooves are designed to retain the lead terminals of electronic components, preventing them from falling off or being displaced due to inertia forces during intermittent feeding. The system also incorporates a magnet mounted to a rail, which guides the timing belt and attracts the lead terminals to the retainer grooves. This allows for stable conveyance of electronic components not only horizontally but also in vertical or circular arc directions.

Another significant patent is an apparatus for automatically taping electronic components. This apparatus is designed so that when a timing belt, which retains lead terminals in its retainer grooves, engages with a toothed pulley of a first rotary drum, the lead terminals are lifted and transferred to the first rotary drum. The electronic components are then transferred from the first drum to a third rotary drum via a second rotary drum, while being retained by their retainer teeth. A base tape is fed to the periphery of the third rotary drum, and an adhesive tape is applied to fix the lead terminals securely.
