Device for controlling a flow of cardboard tubular cores (1) adapted to produce logs of paper material and intended to be stored in a collection point (2) placed downstream of the same device, including more conveyors (5; 7) each of which is adapted for carrying the said tubular cores (1) up to the entry point (6D) of a respective guide channel (6) having an entry point (6D) and an exit point (6F), interception devices (8) adapted for intercepting the tubular cores (1), the interception devices being arranged and acting on each of the channels (6) to adjust the flow of the tubular cores through the respective exit points (6F), and programmable device (UE) adapted for activating and deactivating the interception device (8). The interception devices (8) are adapted to selectively form two nips (N1, N2) inside the guide channel (6), the nips (N1, N2) being selectively formed at a predetermined distance from each other.

The disclosure relates generally to pipe preparation and processing, more particularly, to a loading and unloading station for moving pipes through the preparation and processing stages of production. The pipe loading and unloading station may include an upstream ramp including a plurality of movable pipe separator tabs, a downstream ramp including a plurality of movable backstop tabs, and a conveyor located between the upstream ramp and downstream ramp and including a plurality of movable ejectors.

A container supplying unit is provided with a container storing part, a container discharging part, and a container aligning part. The container aligning part is provided with an aligning rail and a shutter mechanism. The shutter mechanism is provided with a support frame, a rotating shaft, a first shutter member, a second shutter member, and a driver. The first shutter member is fixed to the rotating shaft, and has a first shutter piece which prevents/allows the movement of the container. The second shutter member is fixed to the rotating shaft at a position spaced farther apart from a feeding position than the first shutter member, and has a second shutter piece which prevents/allows the movement of the container.

An apparatus for conveying electronic devices comprises a track for conveying a plurality of electronic devices in a row towards a pick-up position on the track where the electronic devices are removed by a pick-up device. A guiding portion located over the track has a first restraining mechanism formed in the guiding portion that is operative to restrain and secure a first electronic device at a first position next to the pick-up position and a second restraining mechanism formed in the guiding portion that is operative to restrain and secure a second electronic device at a second position away from the pick-up position which is immediately subsequent to the first position. The first and second electronic devices are configured to be released and conveyed towards the pick-up position when the first and second restraining mechanisms respectively are deactivated. A corresponding method is also provided.

An automated storage and retrieval system includes a storage grid configured to store a plurality of storage containers in vertical stacks, a plurality of remotely operated vehicles, and a rail system including rails and tracks onto which the plurality of remotely operated vehicle operates. The automated storage and retrieval system includes a first area and a second area. The first area is linked to the second area for passage of one or more of the plurality of remotely operated vehicles by a vehicle pen. The vehicle pen includes an entry barrier and an exit barrier to regulate the passage of the of one or more vehicles between the first and second area. The entry and exit barriers are moveable between an open position in which passage of the one or more of the vehicles is allowed, and a closed position in which passage of the one or more vehicles is restricted. The entry and exit barriers are regulated such that the entrance barrier can be opened only when the exit barrier is closed, and vice versa.
