Publication number: 20230068234Abstract: Provided is a method for manufacturing a ribbon piece that allows suppressing a damage of a rotary die cutter. A method for manufacturing a ribbon piece of the present disclosure includes punching out a ribbon piece from a ribbon material using a rotary die cutter. The rotary die cutter includes a die roll and an anvil roll. The die roll includes a die roll body, and a cutting blade is formed to protrude on an outer peripheral surface of the die roll body. The anvil roll includes an anvil roll body, a groove is provided on an outer peripheral surface of the anvil roll body, and the cutting blade is engageable with the groove with a space.Type: ApplicationFiled: August 22, 2022Publication date: March 2, 2023Applicants: TOYOTA JIDOSHA KABUSHIKI KAISHA, SANJO MACHINE WORKS, LTD., KOTO ENGRAVING CO., LTD.Inventors: Akinori TOMIOKA, Takuya SUKEDA, Naoki HIRAI, Yoshikiyo KONDO, Masaaki SHIMIZU, Isamu SAKAYORI, Kojiro KATAOKA, Hiroshi MISONO

Patent number: 11492226Abstract: A method of transporting a plurality of sheet-like members containing a magnetic material includes a first step of placing one of the members on an endless belt, and a second step of releasing the member from a portion of the endless belt which is moved and folded back along a roller. The endless belt includes a first magnetic force generating portion that generates first magnetic force, and a second magnetic force generating portion that generates second magnetic force that is stronger than the first magnetic force. In the first step, the member is placed on the belt, such that a first portion of the member containing the magnetic material is located in the first magnetic force generating portion, and a second portion of the member containing the magnetic material and located rearward of the first portion in a conveying direction is located in the second magnetic force generating portion.Type: GrantFiled: May 26, 2021Date of Patent: November 8, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takuya Sukeda, Naoki Hirai, Akinori Tomioka

Publication number: 20200238560Abstract: Provided are rotary dies that can cut amorphous materials while having suppressed wear. The rotary dies are adapted to cut a target, and include an anvil roller, a die cutter, a first elastic portion, and a second elastic portion. The anvil roller rotates while supporting the target. The die cutter has a projecting edge for cutting the target and is configured to rotate. The first elastic portion is arranged on the outer peripheral surface of the anvil roller, and elastically deforms upon contacting the rear surface of the target when the target is cut. The second elastic portion is arranged on the outer peripheral surface of the die cutter, and elastically deforms upon contacting the front surface of the target when the target is cut. The hardness of the first elastic portion is greater than that of the second elastic portion.Type: ApplicationFiled: January 15, 2020Publication date: July 30, 2020Inventors: Hiromichi NAKATA, Noboru SHIMAMOTO, Takuya SUKEDA, Akinori TOMIOKA, Naoki HIRAI
