A link for a conveyor chain includes a first portion and a second portion laterally spaced apart from the first portion. The first portion includes a first sprocket-engaging pin, and the second portion includes a second sprocket-engaging pin. The first sprocket-engaging pin and the second sprocket-engaging pin protrude laterally away from one another. The first sprocket-engaging pin and the second sprocket-engaging pin may each have an oblong cross-section. At least one retainer can secure a connecting pin against movement relative to at least one of the first portion and the second portion, and each retainer can be positioned substantially within one of the first portion and the second portion.

A conveyor controller for being implemented into a conveyor system includes control circuitry and one or more network interfaces for coupling with other conveyor controllers. In one embodiment, the control circuitry configured for detecting whether another conveyor controller is connected and to determine which network interface is used in order to set the direction of the conveyor system. In another embodiment, the control circuitry is configured, to receive configuration data from a conveyor controller connected to a network interface, and to detect if another conveyor controller is and to transmit configuration message to another conveyor controller that includes additional configuration data associated with the conveyor controller. In still another embodiment, the control circuitry transmits configuration data to a replacement conveyor controller upon getting a request from the replacement conveyor controller that has been connected to a network interface.

A conveyor assembly is provided for use with a mobile vehicle. The conveyor assembly includes a conveyor module. The conveyor module includes a first roller assembly. The first roller assembly includes a first rotatable roller body and a second rotatable roller body. The first and second roller bodies are interconnected to each other in such a manner as to share a first rotational axis yet be at least substantially rotationally independent of each other, such that each of the first and second roller bodies can rotate without causing or interfering with rotation of the other of the first and second roller bodies.

A conveyor chain includes a first flight including a first side portion having a first aperture, a first flight bar, and a first sprocket-engaging portion. The conveyor chain also includes a second flight including a second side portion having a second aperture, a second flight bar, and a second sprocket-engaging portion. The conveyor chain further includes a connecting pin having a first end portion received within the first aperture and a second end portion received within the second aperture. The connecting pin couples the first and second flights together. The first sprocket-engaging portion is positioned laterally outwardly of the first end portion of the connecting pin and the second sprocket-engaging portion is positioned laterally outwardly of the second end portion of the connecting pin.

A method for state monitoring in a conveyor system, and also to a control unit, to a motorized roller, to a conveyor zone, to a conveyor section and to a conveyor system for carrying out this method. The method comprises checking for the presence of a reference operating state, determining a current of the motorized roller if the reference operating state is present, and comparing the determined current of the motorized roller with a reference value for the reference operating state.

The invention relates to a motorized conveyor roller, comprising a roller body mounted so as to be able to rotate about a roller axle, a drive unit arranged inside the roller body and designed to generate a rotational movement about the roller axle between an axle element and the roller body. The invention is characterized by a control unit that is arranged inside the roller body and that is designed to receive a state signal from outside the roller body, to generate a control signal that describes a drive characteristic on the basis of the state signal, to control the drive unit by way of the control signal, to generate a self state signal that describes the state signal and/or the drive characteristic, and to transmit this self state signal outside the roller body.
