Transfer system for transferring items, which transfer system comprises a first transfer device for receiving the items, a second transfer device for discharging the items, and a buffer device for buffering items between the first transfer device and the second transfer device, wherein the first transfer device comprises a first transfer rotator and the second transfer device comprises a second transfer rotator and the transfer system is configured to adjust at least one of a first transfer speed of the first transfer rotator and a second transfer speed of the second transfer rotator.

A buffering device comprises a frame and a conveyor belt, a supply station, a discharge station, a first reversing member reverses the conveying direction of the conveyor belt, and a return guide includes a second reversing member. The buffering device is configured such that the conveyor belt moves from the supply station via the first reversing member to the discharge station, after which the conveyor belt is guided back to the supply station via the return guide. A portion of the conveyor belt n forms a buffer section of which the length varies. The remaining portion of the conveyor belt forms a compensation section for compensating a change of length of the buffer section during simultaneous displacement of the first and second reversing members with respect to the frame. The first reversing member includes a buffer carriage for radially guiding the conveyor belt, which guide is fixed to the carriage.

A cleaning system for a transporting and storing device having adjustable capacity for tobacco industry rod-like elements, the device comprising at least one circular conveyor located on a stationary support element of the device and at least one circular conveyor of the device located on a rotary support element, wherein the conveyors are arranged one above another. The cleaning system comprises a plurality of cleaning units attached to the support elements and oriented towards a transporting surface of the conveyor located below a corresponding cleaning unit of the plurality of cleaning units and configured to remove contaminations from the transporting surface of the conveyor. At least a first cleaning unit of the plurality of cleaning units is attached to the stationary support element and at least a second cleaning unit of the plurality of cleaning units is attached to the rotary support element.

A device for controlling the temperature of foods along a conveying path includes a buffer unit arranged in a region between a loading station and an unloading station. The buffer unit has at least two deflecting rollers. A first deflecting roller engages, in a first portion of a conveying device, in a continuous conveying chain, continuous conveying belt, or the like, which moves from the loading station toward the unloading station when driven. A second deflecting roller engages, in a second portion of a conveying device, in the continuous conveying chain, continuous conveying belt, or the like, which moves from the unloading station toward the loading station when driven. The first drive unit is coupled in the region of the loading station and a second drive unit is coupled in the region of the unloading station to the continuous conveying chain, continuous conveying belt, or the like.

An accumulator has a control system for controlling motion of a plurality of buckets on a continuous loop and logs traversing on a log transfer device. The log transfer device delivers a log from an entrance of the log transfer device to a bucket infeed on the accumulator. The bucket infeed receives a log from the log transfer device and allows a bucket to receive the log from the log transfer device. A time for the log to move from the entrance of the log transfer device to the bucket infeed is determined. Based on the time for the log to move from the entrance of the log transfer device to the bucket infeed, the control system controls the accumulator drive to move the continuous loop such that a bucket in the plurality of buckets is positioned at the bucket infeed with sufficient time to allow the bucket to receive the log from the log transfer device.

A conveyor accumulator for conveying articles comprises first and second parallel rails, a turnaround wheel, an endless loop conveyor chain, an infeed drive device, and an outfeed drive device. Each of the rails comprises a support surface and a guide surface. The support surfaces slope downward as they extend outboard of the center plane of the accumulator. The turnaround wheel is movable between the guide rails. The conveyor chain is slideable along and supported against gravity by at least the support surfaces of the first and second rails and is prevented from moving outboard by the guide surfaces. The turnaround wheel is configured to move in a manner extending and, alternatively, contracting the path of the portion of the conveyor chain configured to hold articles. The turnaround wheel is configured and adapted to cause the conveyor chain to bank as the conveyor chain extends around the turnaround wheel.

An accumulating portal conveyor comprises a conveyor belt, a frame for supporting and guiding the belt, which frame includes a first helical path and a second helical path spaced from the first helical path, a bridging path and a return path. Under operating conditions the belt successively follows the first helical path upwardly, the bridging path, the second helical path downwardly and the return path, and such that in transverse direction of an upright plane through central centerlines of the first and second helical paths. The bridging path includes a static part having a fixed position with respect to the helical paths and a dynamic portion displaceable in transverse direction of the upright plane to change the path length of the belt. At least a portion of the return path is displaceable for compensating the change of the path length of the belt at the bridging path.

A conveyor apparatus is provided. The conveyor apparatus includes a rail formed in a closed curve line, a chain conveyor that moves along the rail, a driver that drives the chain conveyor, and a first and a second variable conveyors that relatively vary lengths of at least two portions of the chain conveyor so that a section of the chain conveyor remains in position while other portions of the chain conveyor moving along the rail.

According to an embodiment, a tray for a physical distribution sorter includes a frame body, first and second pulleys, first and second rotating plates, and a wire. The frame body moves in a predetermined direction on a track of the physical distribution sorter. The first and second pulleys rotate about a predetermined axis with respect to the frame body. The first rotating plates rotate with rotation of the first pulley. The second rotating plate rotates with rotation of the second pulley. The wire is wound around the first and second pulleys. When the wire is unwound from the second pulley and wound around the first pulley, the first and second rotating plates rotate and close. When the wire is unwound from the first pulley and wound around the second pulley, the first and second rotating plates rotate and open in a double-open manner.
