Examples of automated gemstone feeding are described. According to an example, a gemstone feeding machine includes a conveyor belt assembly to feed holders carrying gemstones. The conveyor belt assembly can include a plurality of conveyor belts in two sets positioned parallel to each other and the two sets can move in opposite directions. Each belt in one set can be positioned alternately with respect to each belt in the other set. The assembly can include a fixed guiding plate at a first end of the conveyor belts and a detachable guiding plate adjacent to the loading assembly at a second end of the conveyor belts. The fixed guiding plate and the detachable guiding plate each comprises a plurality of transition profiles in alignment with immediately adjacent conveyor belts.

A transfer device, for transferring components at high speed and inspecting the components, includes a first transfer mechanism including a first transfer section including a first transfer surface that moves along a first transfer path connecting a loading position to a delivery position, and a second transfer mechanism including a second transfer section that moves along a second transfer path connecting a receiving position spaced from the delivery position by a first distance to a discharging position. The second transfer section includes a second transfer surface that continuously rotates about a rotation axis along the second transfer path. A moving direction of the first transfer surface at the delivery position intersects a moving direction of the second transfer surface at the receiving position in a plan view of the first transfer surface. The second transfer mechanism includes a generator that generates an attraction force toward the second transfer surface.

A buffer conveyor comprises a drivable endless conveyor belt which successively follows a transport path from an input station to an output station and a return path. A frame includes two parallel transport path frame legs and a U-shaped transport path bridge. The transport path bridge includes a curved bridge portion and parallel bridge legs extending therefrom. Each transport path frame leg is provided with a transport path frame guide for a lateral contact side of the belt in outward direction as seen from the other frame leg. The transport path bridge is shaped such that along the curved bridge portion and respective twisted regions of the bridge legs adjacent to the curved bridge portion the belt has a transverse down-slope towards the inside of the U-shape and such that the lateral contact side (of the belt at said twisted regions is above the respective transport path frame guides.

A transfer device for use with a conveying apparatus for controlling the flow of articles, including a first conveyor and a second conveyor. The transfer device is disposed generally across and movable along the first and second conveyors. The transfer device includes a belt guide attached to the transfer device. The belt guide includes a base configured to attach to an actuating frame of the transfer device and a tension roller that slideably engages with a portion of the base to aid in conveying articles between the first conveyor and second conveyor.

The invention relates to a method and a device for buffering containers in a container treatment plant. According thereto, containers are put into storage in a grouped manner in single file on at least one input conveyor belt, are moved in single file on a transversely adjoining buffering surface of shuttles, guided and driven individually on rails, having row pushers, in a buffering direction extending transversely to the input direction, and are taken out of storage on at least one output conveyor belt. Since, furthermore, containers are taken out of storage from the buffering surface by means of branching conveyor belts integrated in the buffering surface, transversely to the buffering direction and independently of the input conveyor belt and output conveyor belt, and/or are put into storage on the buffering surface, it is possible for container flows to be distributed flexibly and combined on the buffering surface.

Transport assembly of the smoking products manufacturing industry; the transport assembly comprises: a first conveying system for feeding components of the smoking products along a first conveying path to a first input station of a first manufacturing machine; and a second conveying system for conveying articles obtained from the components along a second conveying path from a first output station of the first machine to an input station of a second manufacturing machine (for example, a packaging machine); the first conveying system is configured to change the length of a stretch of the first conveying path; the second conveying system is configured to change the length of a stretch of the second conveying path; the mentioned stretches of the first path and of the second path are arranged overlapping one another and/or side by side.
