Patent number: 5322156Abstract: The present invention is a vehicle body conveying apparatus in which a vehicle body (20) conveyed by a shuttle conveyor (32) is then conveyed in the order of an inclining belt conveyor (1) and a slat conveyor (21). A miniconveyor (26) is disposed between the inclining belt conveyor (1) and the slat conveyor (21) in such a relation that a rear end of the miniconveyor (26) overlaps a delivery side of the inclining belt conveyor (1), and the front end overlaps a receiving side of the slat conveyor (21) so as to ensure smooth transfer of the vehicle body (20) between them. Further, the inclining belt conveyor (1) is inclined by an elevating mechanism (8) to separate the vehicle body (20) from the shuttle conveyor (32).Type: GrantFiled: April 29, 1993Date of Patent: June 21, 1994Assignee: Mitsubishi Jidosha Kogyo Kabushiki KaishaInventors: Takuya Kakita, Noriyuki Inoue, Shoichi Okada, Yoshiki Nakamura, Wakaharu Ikeda, Akira Mikami, Akiyoshi Kimura, Masayuki Aihara, Hisashi Fujiwara, Yuji Watanabe

Patent number: 5297483Abstract: Left side panels and right side panel are produced in a left side panel production line and a right side panel production line, respectively By vertical lifters, each left side panel and each right side panel are lifted at the delivery stations and then transferred to runners at work transfer positions. The runner with the left side panel held thereon travels along a rail while the runner with the right side panel held thereon travels along a rail. Both runners are stopped at a standby position and then conveyed to a runner transfer position simultaneously. The runners with the left and right side panels held thereon, respectively, are loaded on the traverser and then conveyed to a drop lifter arranged above a main body assembly line. The left and right side panels are transferred to the drop lifter. The drop lifter then descends and feeds the left and right side panels simultaneously on opposite sides of a floor panel in the main body assembly line.Type: GrantFiled: October 28, 1992Date of Patent: March 29, 1994Assignee: Mitsubishi Jidosha Kogyo Kabushiki KaishaInventors: Takuya Kakida, Noriyuki Inoue, Shoichi Okada, Yoshiki Nakamura, Wakaharu Ikeda, Akira Mikami, Akiyoshi Kimura, Masayuki Aihara, Hisashi Fujiwara, Yuji Watanabe
