A disinfecting device using ultraviolet light is configured to sit on top of an existing conveyor belt or rollers. The disinfecting device has a housing, an inlet, an outlet, a plurality of rollers within the housing, one or more disinfecting lights positioned above the rollers, and at least one disinfecting light positioned beneath the rollers. The plurality of rollers carry the item upward, passing over at least one disinfecting light while other disinfecting lights are positioned above the item. The item is then returned to the conveyor belt to continue onward.

A split drive sprocket assembly includes: a first sprocket portion and a second sprocket portion configured to be joined along an opposing mating surface to form a cylindrical sprocket body; a series of teeth extending radially from a circumferential end of the first sprocket portion and the second sprocket portion; a first shoulder connected to the first sprocket portion and extending radially so as to extend from an axial further than the teeth extends from the axial and spaced axially apart from the teeth; a second shoulder connected to the second sprocket portion and extending radially so as to extend from the axial further than the teeth extends from the axial and spaced axially apart from the teeth. The first sprocket portion and the second sprocket portion are configured to engage a belt with the teeth and the first and second shoulder are configured to overlap with the belt while the teeth are engaged with the belt.

An apparatus for storage of a carrying material, includes: a body frame; a plurality of loading members installed on the body frame and disposed such that a carrying material forms a plurality of layers in upper and lower directions; a driving unit connected to at least one of the plurality of loading members; and an auxiliary coupling unit provided in a portion of the plurality of loading members for attachment and detachment to and from a neighboring loading member, wherein the plurality of loading members are provided with a plurality of first loading members fixedly installed at a lower end portion of the body frame, and a plurality of second loading members disposed above the first loading member and movably installed on the body frame, wherein the driving unit is connected to at least one of the plurality of second loading members, wherein the auxiliary coupling unit includes an electromagnet installed at one end of the second loading members, and a magnetic body installed at the other end of the second loading members and the body frame to correspond to the electromagnet.

Disclosed is a conveyor system and method for advancing an item relative to a transport axis. The conveyor system includes a conveyor belt and a modular drive assembly having at least one drive module and at least one take-up module. Each drive module and each take-up module has a housing and a pulley assembly positioned within the housing. The respective positions of the housings of the at least one drive module and the at least one take-up module relative to the transport axis are selectively adjustable to modify the conveyor movement pathway. Moreover, the drive module can also include a drive pulley removal apparatus that is detachably secured within the housing for selective removal and replacement of a drive pulley.

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 roller assembly for use in a conveyor system is disclosed. The roller assembly includes a shaft and a roller rotatably mounted to the shaft. In one embodiment, the roller is made of ultra-high molecular weight plastic. Each roller has first and second ends. The roller assembly further includes a first collar and a second collar mounted on the shaft. The first collar is positioned at the first end of the roller and the second collar is positioned at the second end of the roller. Each collar is selectably affixable to the shaft so as to hold the roller in a fixed position along the length of the shaft.

A two part sprocket wheel engages modular belt modules in a conveyor belt. The sprocket wheel's periphery elements' outer edges form a full circle. On each inner periphery four engagement ridges are provided. When the sprocket wheel is mounted around the axle, only the engagement ridges touch and engage the axle. The sprocket wheel construction between the engagement ridges is removed from the drive axle. It is possible to flush and clean the areas around the drive axle being partly covered by the sprocket wheel in an easy and accessible manner. The engagement ridges have a very limited engagement area in order to contact the drive axle and thereby convey the torque forces from the drive axle to the teeth of the sprocket wheel. The engagement ridges are in very firm engagement with the drive axles, such that no material may remain where the engagement ridges engage the drive axles.
