Title:
LINEAR MOTOR TRANSPORT SYSTEM AND METHOD FOR OPERATING SAME
Document Type and Number:
WIPO Patent Application WO/2022/209472
Kind Code:
A1
Abstract:
This linear motor transport system 100 comprises a carrier 10 to which a linear scale 14 and a reference mark 16 are fixed, a linear motor 12 that moves the carrier 10 along a route D, a plurality of sensors 18 arranged along the route D, and a control device 20. When the linear motor 12 is controlled such that the carrier 10 is moved as an initial process, the control device 20 identifies the position of the carrier 10 not on the basis of a reference-mark 14-related output produced by a sensor 18 that has not detected the linear scale 16 among the plurality of sensors 18, but rather on the basis of a reference-mark 14-related output produced by a sensor 18 that has detected the linear scale 16.
