<p>A device body (10) has an ejector (13), and the ejector (13) has a nozzle (15) and a diffuser (17) in which a suction hole (18) is formed. A supply-air flow passage (35) is formed between the nozzle (15) and a connection port (34) to which a compressed-air supply source (32) is connected. The supply-air flow passage (35) is opened and closed by a supply-air control solenoid valve (31). A suction device (43) for vacuum-sucking a workpiece (W) is connected through a vacuum pipe (44) to a vacuum flow passage (42) communicating with the suction hole (18). An air tank (40) in which the compressed air supplied from the supply-air flow passage (35) is accumulated is formed in the device body (10). The compressed air from the air tank (40) is supplied to the nozzle (15) at the beginning of suction of the workpiece by the suction device (43).</p> |
