Patent number: 11766754Abstract: A conveyance apparatus includes two clamp mechanisms. Each of the clamp mechanisms is configured to freely change its state among a fully clamping state, a semi-clamping state, and a non-clamping state. When an object is delivered from a first clamp mechanism that is holding the object to a second clamp mechanism, the second clamp mechanism is brought into the semi-clamping state to temporarily hold the object. Then, the first clamp mechanism is brought into the non-clamping state and the second clamp mechanism is brought into the fully clamping state.Type: GrantFiled: March 27, 2018Date of Patent: September 26, 2023Assignee: AISIN CORPORATIONInventors: Yuichiro Yoshimura, Atsushi Kohama, Atsushi Yoshida, Makoto Iida, Syuntaro Nagai

Patent number: 7137940Abstract: Machining is possible in such a manner that an optional position of a workpiece is positioned just under a tool by rotation of a turn table in a C-axis direction, movement of the turn table in a Y-axis direction, and movement of a spindle in a Z-axis direction, so that a width of a main unit in a X-axis direction can be made shorter in comparison with machining by moving the turn table in the X-axis direction. Besides, the turn table located on a front side of the main unit, an ATC located on the rear side thereof, and a separated control panel located on the rear side of the ATC, independent from the main unit can also make the width of a machining center in the X-axis direction shorter.Type: GrantFiled: April 21, 2006Date of Patent: November 21, 2006Assignees: Aisin AW Co., Ltd., Yamazaki Mazak Kabushiki KaishaInventors: Takao Taniguchi, Toshiyuki Andou, Mitsuhiro Yamada, Kazutaka Murai, Yuichiro Yoshimura, Jiro Nishida, Atsushi Kohama, Shigeto Noma, Michio Norimatsu, Seiichi Kodama, Haruhiko Koike
