Patent number: 11926246Abstract: In a local cart traveling system, a frame track includes first and second metal rails each with an L-shaped cross section and facing each other. A local cart is within the frame track, and includes a first electricity receiving tire and a second electricity receiving tire to travel on horizontal travel surfaces of the rails. A voltage supplier supplies an AC voltage to the travel surfaces, so that the first metal rail and a first electricity receiving tire define a first capacitor and the second metal rail and the second electricity receiving tire define a second capacitor. The local cart includes a power receiver to receive AC power, and a travel motor that receives power after the AC power is rectified. The frame track includes a connecting plate as an electrical insulator covering portions of the surfaces of vertical walls of the first metal rail and the second metal rail.Type: GrantFiled: June 1, 2018Date of Patent: March 12, 2024Assignees: MURATA MACHINERY, LTD., NATIONAL UNIVERSITY CORPORATION TOYOHASHI UNIVERSITY OF TECHNOLOGYInventors: Minoru Mizutani, Kazuhiro Ishikawa, Masafumi Hayakawa, Takashi Ohira, Naoki Sakai, Hiroki Kuniyoshi, Makoto Teramoto
