BELT CONVEYER WITH FACILITY FOR CONTINUOUS BELT CENTERING Russian patent published in 2008 - IPC B65G15/08 B65G39/71 B65G15/64 B65G21/12 

FIELD: transportation.

SUBSTANCE: conveyer contains immovable grooved roller carriages with capability of conveyer belt bearing to it and facility for continuous belt centering containing carrier mounted on conveyer frame and rotatable and located on carrier taper rollers. Facility for continuous belt centering is implemented as two carriers located from both sides of immovable roller carriage of conveyer with rotatable carriers in a vertical plane relative to horizontal axes, oriented by conveyer longitudinal axis. Taper rollers are mounted on one free end of each carrier, and on the other end of carrier it is fixed friction element with capability of its interaction with underside of conveyor belt. Each taper roller is implemented of turned to longitudinal axis of conveyer side of its plain spigot portion and gradually adjoined to it flare section with alternating taper angle, increasing right-about. Taper rollers and friction elements on both carriers are located contrariwise to each other. Length of plain spigot portion of taper roller is accepted not less then value of conveyer belt transverse displacement during conveyer operating. Carriers are spring-loaded to conveyer frame with spring location at both sides of axes and at equally-spaced belt location relative to conveyer longitudinal axis - are balanced relative to axes. Plain spigot portion of each taper roller and each friction element are located with minimal open relative to underside of conveyor belt.

EFFECT: invention allows providing of increasing of centering action for conveyer belt.
