Patent number: 11548121Abstract: The invention relates to a suction device (12) comprising a valve housing (18), a flexible partition wall (28) which runs in such a way that a control space (30) extends on one side and an intake side (21) lies on the other side, wherein the control space (30) is connected to the intake side (21) via a throttle passage (38), wherein the throttle passage (38) is formed in such a way that a flow resistance for flows is defined by the throttle passage (38) in such a way that, in the case of free suction, a negative pressure in relation to the intake side occurs in the control space (30) on account of the flow resistance.Type: GrantFiled: March 29, 2018Date of Patent: January 10, 2023Assignees: J. SCHMALZ GMBH, TRUMPF WERKZEUGMASCHINEN GMBH & CO. KGInventors: Rainer Hoehn, Jonas Horst, Magnus Deiss

Patent number: 11192167Abstract: A loading and unloading device for a machine, a machine for machining panel-like workpieces, and a workpiece support for such a machine and a method for loading and unloading such a machine, having a loading and unloading module, wherein the loading and unloading module has a vertically upwardly oriented raising device for lifting a cut-free workpiece part and a vertically downwardly oriented gripping device (38) for holding an unmachined, panel-like workpiece.Type: GrantFiled: November 27, 2018Date of Patent: December 7, 2021Assignees: TRUMPF Werkzeugmaschinen GmbH + Co. KG, J. Schmalz GmbHInventors: Magnus Deiss, Peter Epperlein, Frank Schmauder, Fabian Gaeckle, Jens Ottnad, Heinz-Juergen Prokop, Stefan Stroebel, Walter Dunkmann, Thomas Eisele, Rainer Hoehn, Dirk Plaueln, Hermann Reinisch

Patent number: 9676565Abstract: A vacuum gripping device comprising a plurality of suction bodies, each comprising a suction chamber for applying to a workpiece to be gripped, a suction valve is associated with each suction point, wherein each suction valve comprises a vacuum supply side for connection to a vacuum supply device and a suction side connected to the suction chamber of the assigned suction body, wherein the suction valve comprises a valve body, moveable between an open position and a closed position, wherein the valve body is arranged on a flexible control membrane which delimits a control chamber; in such a way that the valve body is moveable from the open position into the closed position using deformation of the control membrane, and wherein a membrane cloth extending across multiple or all suction points is arranged in the gripper housing.Type: GrantFiled: September 16, 2014Date of Patent: June 13, 2017Assignee: J. Schmalz GmbHInventors: Thomas Eisele, Rainer Höhn, Walter Dunkmann

Patent number: 9545726Abstract: A valve has suction and vacuum supply sides and a valve housing inbetween, a flexible dividing wall delimiting a control space in the valve housing connected to the vacuum supply side via a vacuum passage, and a valve body arranged on the dividing wall moving between open/closed positions. The valve body has a sealing portion sealing off or opening up the vacuum passage in closed/open positions. Based on a control space vacuum, the volume of the control space reduces with a deformation of the dividing wall, and the valve body moves from the open to closed position. The valve body has a suction-side passage connecting the suction side to the control space so air is suctioned from the suction side into the control space, and penetrates the dividing wall with the sealing portion on one side and a guide portion on the other side of the dividing wall.Type: GrantFiled: September 16, 2014Date of Patent: January 17, 2017Assignee: J.SCHMALZ GmbHInventors: Thomas Eisele, Rainer Hoehn
