Claims

[Scope of Claim for Utility Model Registration] Ventilation-type vacuum generation means for generating negative pressure in a vacuum cup connected to the main body by discharging pressurized air supplied upstream from an air source from an exhaust port on the downstream side; an opening/closing means for opening and closing an exhaust port of the vacuum generating means; and a control means for operating the opening/closing means to open the exhaust port when the vacuum cup adsorbs a workpiece and close it when the suction is released; The vacuum generating means is configured to clean the vacuum cup by releasing pressurized air from the main body of the vacuum forming means to the vacuum cup when the opening/closing means is operated to close the exhaust port. Vacuum suction device.
