Abstract
This invention relates to a conveyor apparatus or roller train with a series of conveyor stations, the support rollers of which can be optionally driven or shut off. To create an economical and reliable roller train with a separation and storage function, each conveyor station of the roller train has its own drive motor with a switchgear unit and the several switchgear units are connected together for control purposes into a cascade so that only the first switchgear unit of the cascade is connected to a higher-voltage switch cabinet.
