Patent number: 9821975Abstract: A second tape feeding mechanism 20B is permitted to idly rotate only in a first rotating direction and has a biasing mechanism 25 which biases a carrier tape 14 against a sprocket 21B so that the carrier tape 14 is brought into engagement with the sprocket 21B. With a preceding tape 14(1) kept in engagement with the sprocket 21B, a leading end portion of a following tape 14 (2) is inserted between the sprocket 21B and the preceding tape 14 (1), and the preceding tape 14 (1) is biased by the biasing means 25 so that the following tape 14(2) is brought into engagement with the sprocket 21B.Type: GrantFiled: March 4, 2013Date of Patent: November 21, 2017Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Kazunori Kanai, Junkei Shimizu, Tatsuo Nakamura

Patent number: 9611114Abstract: There is provided a tape feeder that feeds a carrier tape to supply components to a component suction position for a mounting head in a component mounting apparatus. The tape feeder includes a first tape feed mechanism which is provided in a downstream side and feeds a preceding tape to the component suction position, and a second tape feed mechanism provided in an upstream side and feeds a following tape from a tape introducing port side toward the first tape feed mechanism. The tape feeder also includes a tape slipping-off informing unit which informs the component mounting apparatus that the following tape is slipped off from the second tape feed mechanism. For example, the tape slipping-off informing unit decides that the following tape is slipped off when a rotation of a sprocket of the second tape feed mechanism in an opposite direction is detected.Type: GrantFiled: November 25, 2014Date of Patent: April 4, 2017Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Junkei Shimizu, Kazunori Kanai, Masayuki Higashi, Tatsuo Yamamura

Patent number: 6862803Abstract: A parts mounting method employing a suction section having a plurality of suction nozzles is provided. The suction section is moved to a parts supply section in which a plurality of parts are suctioned by the suction nozzles at the same time. The parts are then mounted onto a board. The suction nozzles are divided into groups: a first group having a shift amount within an allowable range in which simultaneous suction is possible; and a second group having a shift amount outside the allowable range in which simultaneous suction is possible. The parts are then sucked at the same time for each of the groups.Type: GrantFiled: August 28, 2001Date of Patent: March 8, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takeyuki Kawase, Junkei Shimizu, Hiroshi Uchiyama, Noriaki Yoshida
