Abstract
This conveyor apparatus, when conveying articles between adjoining stations, under the control of the control device on the basis of conveying state conveyance is carried out by driving by both the linear motor unit and the servomotor unit in at least one of the low speed regions (acceleration region at the initial stage of conveyance and deceleration region at the last stage of conveyance) and by driving by the servomotor unit in the intermediate region at the intermediate stage of conveyance. Therefore, conveyance in the low speed region is assisted by the linear motor unit which generates large thrust, with the result that acceleration and deceleration in the low speed region are enhanced effectively and no deviation is caused at each speed change point by the servomotor unit of high positioning precision.
