US Patent 10511247 Linear conveyor device and drive control method therefor

In a linear conveyor device, each driver in each of sensor structural bodies includes a sensor position calculation part, a position identification part and a power supply control part. The sensor position calculation part calculates sensor position data of a sensor which forms a sensor structural body to which the sensor position calculation part per se belongs based on first sensor distance data which is stored in a data storage part. The position identification part identifies the position of a slider based on addition data obtained by adding sensor position data by the sensor position calculation part and detection data by a sensor which forms the sensor structural body. Then, the power supply control part drives a linear motor by performing a power supply control of a linear motor stator corresponding to the sensor structural body based on an identification result obtained by the position identification part.
