CHAIN CONVEYOR Russian patent published in 2003 - IPC

FIELD: tire industry mechanical engineering; transportation facilities. SUBSTANCE: invention relates to methods of transportation of piece articles for instance, tires and their parts to be fed to prescribed processing station in strictly defined and orientated position. Proposed chain conveyor contains two parallel pull chains, drive and tension sprockets, guide, drive and frame. Both pull chains are provided with flats and plates with two pushers in form of rods installed in turn, and guide roll table in zone of unloading. Height of pushers is calculated by formula H=(0.75-0.9)2B where H is height of pusher, B is width of tire tread. Guide roll table consists of three sections, middle one being depressed by h=(0.6-1.2)R where R is radius of rollers of roll table. Clearance is formed between sections of guide roll table whose size S=(1.5-2.0)d where d is diameter of pusher rods. Proposed invention makes it possible to decrease length of conveyor and thus cut down production area for its mounting. EFFECT: enlarged operating capabilities, improved reliability in operation. 5 dwg
