Title: Hironari Yamada: Innovator in Rotary Die Cutting Technology

Introduction

Hironari Yamada is a notable inventor based in Mihara, Japan. He has made significant contributions to the field of rotary die cutting technology, holding two patents that enhance operational efficiency in this area. His work is primarily associated with Mitsubishi Heavy Industries Printing & Packaging Machinery, Ltd.

Latest Patents

Yamada's latest patents include a blade mount of a rotary die cutter and a method and device for fixing the blade mount. The blade mount is designed to be attached or detached without the use of bolts, which saves time during the attaching and detaching process. This innovation aims to enhance the operational efficiency of rotary die cutters. The mechanism involves two fixing rings that are freely fitted to a knife cylinder, with a driving unit that rotates a screw axis to move the mounts. This design allows yoke plates on the moving mounts to shift the fixing rings to the end of the blade mount, where an activated unit secures the fixing rings to the outer circumference of the knife cylinder. Once the fixing rings are secured, the yoke plates are separated to prevent abrasion.

Another patent focuses on a punching scrap removal device and blade mount for rotary die cutters. This invention improves work efficiency by eliminating the need to attach and remove push rods during the installation and dismounting of the blade mount. It also reduces the wear on push rods used for ejecting punching scrap from a punching blade. The design features first push rods that are movably inserted into the knife cylinder and second push rods that are movably inserted into the blade mount. A scrap push lever is mounted on the outer end of the second push rod to facilitate the removal of punching scrap.
