A drive roller assembly for a conveyor system includes a drive roller having a longitudinal axis, the drive roller having a roller body and a shaft. A support structure rotatably supports a second axial end portion of the shaft and a drive for rotatably driving the drive roller. A first axial end portion of the shaft and the drive are rotatably coupled in an axially engaged condition in which the drive roller is in rotatable engagement with the drive and in which the drive is axially releasable. The support is configured and adapted to be detachably attached to an attachment portion of the support structure to maintain the drive roller rotatably supported when attached and to allow the drive roller to be removed from the support structure when detached.

Described herein are industrial application systems for treating (e.g., forming protective coatings on) produce, agricultural products, or other items. An exemplary application system can include a bed comprising a plurality of rollers, one or more sprayers over a first portion of the bed, one or more blowers over a second portion of the bed, a mixing system configured to prepare a mixture comprising a coating agent in a solvent, and a liquid delivery system connected inline between the mixing system and the one or more sprayers. Items placed on the bed can have the mixture applied to their surfaces via the one or more sprayers, after which the one or more blowers can at least partially remove the solvent from the surfaces of the perishable items, thereby causing the protective coatings to be formed over the perishable items.

A transport system (S) comprises a guide path (1) and at least one mobile carriage (2) movable along the guide path (1). The guide path (1) comprises a first guide profile (11) and a second guide profile (12). A single pair of rollers (31, 32) are mounted rotatably in an independent way to one another on a first rotation shaft (51) borne by the mobile carriage (2) so as to be in contact with the first guide profile (11). A first pair of rollers (41, 42) and a second pair of rollers (43, 44) are mounted rotatably in an independent way to one another on a second rotation shaft (52) and on a third rotation shaft (53) borne by the mobile carriage (2) so as to be in contact with the second guide profile (12).

A transport system includes a guide rail having a loop-wound pathway with straight portions and curved portions linking the straight portions. A carriage is movable along the guide rail, a first and a second shaft being mounted on the carriage transversely to the carriage movement direction. A first pair of rollers are mounted rotatably on the first shaft so that a first roller contacts the internal wall of the guide rail and a second roller contacts the external wall of the guide rail. A second pair of rollers mounted rotatably on the second shaft include a first roller in contact with the internal wall of the guide rail and a second roller in contact with the external wall. The first and the second shaft are mounted on the carriage for pivoting about an axis perpendicular to the carriage.

An efficient flexible sorting device for material flow is provided. The gear A is driven by the rotating motor, and the gear A meshes with the gear B, so that the rotating body can be rotated relative to the main frame according to the sorting direction actually required. The belt motor rotates the driving shaft through the small synchronous pulley, the synchronous belt, and the large synchronous pulley. The driving shaft drives the belt to move along the tensioning roller, the driving shaft, and the guiding pulley. The relative position of the tensioning roller and the rotating body is adjusted through the bolt F, the fixing plate and the nut F to ensure that the belt is tensioned, thereby realizing the sorting process.

A conveyor chain and horizontally oriented guide wheel having a hub, an outer wheel rotatable about the hub and a bearing race between said hub and said outer wheel. An oiling gap, the top opening of which is located radially inwardly of the bearing race, extends outwardly and downwardly and opens into said bearing race, such that a direct downward path to the bearings is eliminated. The hub and the inside of the outer wheel have opposed frustroconical surfaces which define a frustroconical path from the top wheel surface oiling gap opening to the wheel bearings. The guide wheel also includes a blow out gap on the bottom side which is formed by a blow out path which becomes wider than the bearing race as it proceeds downwardly to its opening at the bottom of the wheel, making it easier for debris to be blown out of the bearings either from air blown down through the oiling gap at the top or blown up from the blow out gap at the bottom.
