WORKPIECE FEEDER Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention relates to devices designed for delivery of workpieces using system of vacuum grips for interoperational transfer of parts. Proposed device has base of which vacuum grips connected with vacuum source are mounted. Vacuum grips are provided with rows of nozzles forming bearing surface for holding the parts. Device is furnished with base reciprocating drive. Transportation unit installed on base is coupled with reciprocating drive travel of transportation unit is smaller than feed of part at one working stroke. Pressure chamber of device is formed between vacuum grips and is connected with compressed air source by means of device designed for delivery of compressed air to form lifting force whose value exceeds value of vacuum grips attraction force. Vacuum grips are connected with vacuum source through channels made in transportation unit, being arranged in unit symmetrically relative to pressure chamber. Compressed air delivery device is made in form of pneumatic valve, acceleration pickup of transportation unit for connecting compressed air source with pressure chamber at maximum speed in direction of transportation of parts and delay element to disconnect pressure chamber of compressed air source. EFFECT: enlarged operating capabilities of device. 3 dwg
