VIBROHOPPER Russian patent published in 2001 - IPC

FIELD: automation of production processes in loading of parts into working zones of equipment. SUBSTANCE: vibrohopper has a bowl with spiral chute and outlet chute which is installed on base by means of springy rods, and vibrodrive connected through base with bowl of vibrohopper. Bowl houses plate-type body in ring slot of which bushing is installed for rotation relative to central axis of body. Cylindrical cup is made in central part of body. Body cover installed with flat clearance on end face surface of cup forms ring delivery chamber. Bottom part of bowl is formed over conical surface of bushing and outer surface of body cover. Compressed air gets into ring delivery chamber through tangential inlet hole. Rotation of bushing at peripherical speed exceeding speed of vibratory transportation of parts by spiral chute is provided owing to friction of air stream against outer surface of bushing in ring clearance. Invention creates vibrohopper with new system of delivery of parts into spiral chute covering zone under action of vibration of bottom part of vibrohopper bowl and simultaneous rotation of bushing. EFFECT: intensified process of preliminary orientation of parts, increased capacity of vibrohopper. 3 dwg
