Abstract: Conveyer device including a local controller provided in each zone for controlling a transport operation of the zone, and host controller that reports information relating to a cause of non-transport are included. Host controller includes mouse and the like for receiving, from a user, a selection instruction through which one of a plurality of zones is selected, and report processor that obtains, as clue information, information relating to a phenomenon that can be the cause of the non-transport of a conveyed object, from local controller of the target zone, and reports cause information corresponding to information relating to the cause based on the clue information, when the clue information satisfies a determination condition previously set.

Abstract: Conveyor system may comprise conveyor mechanism(s) provided with transport path(s) along which conveyed object(s) are conveyed to transport destination(s); electric current detector(s) and/or abnormality detector(s) that detect triggering event(s) which may be event(s) occurring at conveyor mechanism(s) due to conveyed object(s) during transport of conveyed object(s); and removal processor(s) that, when triggering event(s) detected by electric current detector(s) and/or abnormality detector(s) satisfy triggering condition(s), cause conveyed object(s) to be transported by conveyor mechanism(s) to removal area(s) which are not transport destination(s).
