Title: Innovations by Yoshiyuki Toishi
Introduction
Yoshiyuki Toishi is a notable inventor based in Toyama, Japan. He has made significant contributions to the field of machinery and automation, holding a total of 4 patents. His work focuses on enhancing the functionality and safety of various mechanical devices.
Latest Patents
One of his latest patents is an apparatus designed to protect a light projector from collisions with a punch in a button setting machine. This innovative apparatus incorporates a lost motion mechanism that creates a delay between the retraction of the light projector and the downward movement of the punch. This ensures that the light projector is safely retracted from the punch's vertical path before any downward movement occurs. The mechanism consists of a shaft with an annular actuating flange, which engages with a cylinder member to lower the punch only after the light projector has been retracted.
Another significant invention by Toishi is a foot-operated press that features a ratchet mechanism. This mechanism connects the foot pedal to the punch of the press, preventing any backward movement of the foot pedal until the punch has fully descended. This design ensures that fastener elements can be properly clinched together with a garment fabric positioned between them, enhancing the efficiency and safety of the pressing process.
