The buffering device serves to temporarily accept products from a product flow in the event of a downstream disruption obstructing the product flow and to deliver the accepted products after the disruption has been eliminated. As conveyor it uses an endless flat top chain, which passes through several loops formed by horizontal deflections in an upper and a lower level. The deflections are arranged in an alternately fixed and horizontally displaceable manner, such that the lengths of the loops are variable.

A multichannel paper feeding system in connection to a vertical storage is disclosed. The multichannel paper feeding system includes a main loop transport device, an internal loop transport device, a plurality of take-out devices, and a plurality of take-out conveyor belts, all of which are disposed between the vertical storage and a cutting machine. The main loop transport device transports a paper roll placed on a main loop rack from the vertical storage to the internal loop transport device, where a main push rod then pushes the paper roll onto an internal loop rack, and the internal loop transport device transports the internal loop rack next to a take-out conveyor belt. The take-out device moves the paper roll from the internal loop rack to the corresponding take-out conveyor belt so that the paper roll can be transported further downstream to a post-processing station for cutting or packaging. Through the internal loop transport device, not only can more take-out conveyor belts be added and may the post-processing production be increased, the transport quality of the paper rolls is also enhanced.

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.

The dynamic package sortation device includes a track for handling a plurality of packages is provided. At least one conveyor extends away from the track towards at least two shipping containers. The at least one conveyor is extendable and retractable for dispensing the packages into a first shipping container of the at least two shipping containers and a second condition for dispensing the packages into a second shipping container of the at least two shipping containers. A controller is provided for providing an instruction to move the at least one conveyor between the first condition and the second condition based on a trigger.

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.
