HORIZONTAL BRANCH DEVICE FOR SELF-PROPELLED CARRIAGE

摘要

A horizontal branch device for a self-propelled carriage, used to transfer a loaded self-propelled carriage (50) between tracks placed crossed each other. The device allows the carriage to be transferred from travel tacks to branched tracks without stopping it, has a simple track branch structure so that less operation trouble occurs in the device even if a large allowance in accuracy and error is provided in the device, can be designed and installed easily with reduced labor, and always assures reliable branching operation. The tracks at least include first tracks (10a, 10b, 110a, 110b) and second tracks (20a, 20b) crossing the first tracks. At the crossing of the tracks, there are provided linear track sections (33, 133) for linearly connecting tracks present on the same line together and curved track sections (34, 134) for connecting crossing tracks together in a curve to thereby provide horizontally rotating rotation tables (31, 131). The tracks are connected with each other by rotationally positioning the tables.
