Document Type and Number:
Japanese Patent JP5753060
Kind Code:
B2
Abstract:
A linear conveyor includes: a linear motor stator (7) which includes a plurality of electromagnets (26) and in which each predetermined section can be individually controlled for conduction; a plurality of conveyance carriages (4) each of which includes a linear motor mover (8); a linear scale which includes scale members (50a to 50c) secured to each of the conveyance carriages, and detectors (28) disposed along a conveyance path; a plurality of motor controllers (C) which individually controls conduction of electromagnets for each section based on the results of detecting the scale members by the detectors; and data storage means (74) which stores position correction data for each conveyance carriage, determined based on the movement error of each conveyance carriage measured in advance using a common measurement jig. Each motor controller controls conduction of the electromagnets using the position correction data stored in the data storage means.
