Abstract
In a contact-free plate conveyor including an arrangement of nozzles each having a cup-like shape widening to a planar rim thereof, air under pressure is supplied to the nozzles such that an air flow is generated toward and through a gap formed between the rims of the cups at high speed which generates a vacuum between the cup rims and the plate so as to hold the plate at a predetermined distance from the nozzle arrangement.
Claims7
A contact-free plate conveyor comprising an areal arrangement of suction nozzles (1) each having a conical cup-like shape widening from an apex toward a planar rim thereof forming with a plate (P) an outlet nozzle structure (3) and means supplying air under pressure via an inlet nozzle structure (2) disposed at the apex to the interior of the suction nozzles in the areal nozzle arrangement such that the air flows toward and through the thin gap outlet nozzle structure (3) formed between the planar rim of the cup and the plate (P) at high speed in a direction parallel to the plate supported on the conveyor whereby a vacuum is generated between the rim area of the cups and the plate (P) thereby holding the plate at a predetermined distance from the nozzle arrangement against a pressure generated within the nozzle cups by the air supplied thereto.
