The invention relates to a suction device () comprising a valve housing (), a flexible partition wall () which runs in such a way that a control space () extends on one side and an intake side () lies on the other side, wherein the control space () is connected to the intake side () via a throttle passage (), wherein the throttle passage () is formed in such a way that a flow resistance for flows is defined by the throttle passage () 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 () on account of the flow resistance. A sealing protrusion () protruding into the interior of the control space () and an associated seal seat () within the control space () are provided, wherein the sealing protrusion () and seal seat () are formed in such a way that, when the sealing protrusion () is placed against the seal seat (), the flow path () through the throttle passage () into the control space () is interrupted within the control space ().

Suction device

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 () for holding an unmachined, panel-like workpiece.

Machine workpiece handling

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.
