A conveyor system comprising: a conveyor mechanism provided with a transport path along which a first conveyed object is conveyed to a prescribed transport destination; an event detector (56, 63) that detects a preestablished triggering event which is an event occurring at the conveyor mechanism due to the first conveyed object during transport of the first conveyed object; a removal area (B1~B4) that is different from the transport destination, and causes the first conveyed object to be removed from the transport path; and a removal processor that, when the triggering event detected by the event detector (56, 63) satisfies a preestablished triggering condition, causes the first conveyed object to be removed by the conveyor mechanism to the removal area (B1~B4) which is not the transport destination corresponding to an original transport destination of the first conveyed object, wherein: the conveyor mechanism is divided into a plurality of zones along a transport direction of the transport path; each of the respective zones is provided with a motor outputting a drive force for conveying the first conveyed object; and the event detector (56, 63) includes an electric current detector that detects, as the triggering event, motor current flowing through the motor at each of the respective zones while the first conveyed object is being conveyed therethrough, wherein the triggering condition includes a second triggering condition that is satisfied when, for a zone of interest which is any one of the plurality of zones, a motor current of interest which is the motor current in the zone of interest exceeds a preestablished first electric current value, and characterized in that the second triggering condition is that the motor current of interest exceeds the first electric current value and the motor current of interest does not exceed a sum of a reference motor current, which is based on a motor current at a zone upstream from the zone of interest, and a preestablished first electric current value width. a conveyor mechanism provided with a transport path along which a first conveyed object is conveyed to a prescribed transport destination; an event detector (56, 63) that detects a preestablished triggering event which is an event occurring at the conveyor mechanism due to the first conveyed object during transport of the first conveyed object; a removal area (B1~B4) that is different from the transport destination, and causes the first conveyed object to be removed from the transport path; and a removal processor that, when the triggering event detected by the event detector (56, 63) satisfies a preestablished triggering condition, causes the first conveyed object to be removed by the conveyor mechanism to the removal area (B1~B4) which is not the transport destination corresponding to an original transport destination of the first conveyed object, wherein: the conveyor mechanism is divided into a plurality of zones along a transport direction of the transport path; each of the respective zones is provided with a motor outputting a drive force for conveying the first conveyed object; and the event detector (56, 63) includes an electric current detector that detects, as the triggering event, motor current flowing through the motor at each of the respective zones while the first conveyed object is being conveyed therethrough, wherein the triggering condition includes a second triggering condition that is satisfied when, for a zone of interest which is any one of the plurality of zones, a motor current of interest which is the motor current in the zone of interest exceeds a preestablished first electric current value, and the conveyor mechanism is divided into a plurality of zones along a transport direction of the transport path; each of the respective zones is provided with a motor outputting a drive force for conveying the first conveyed object; and the event detector (56, 63) includes an electric current detector that detects, as the triggering event, motor current flowing through the motor at each of the respective zones while the first conveyed object is being conveyed therethrough, wherein the triggering condition includes a second triggering condition that is satisfied when, for a zone of interest which is any one of the plurality of zones, a motor current of interest which is the motor current in the zone of interest exceeds a preestablished first electric current value, and
