Embodiment Construction

[0041] exist figure 1 A processing machine 11 is shown in three-dimensional form in the center, which is designed, for example, as a punching machine. For the separate processing of a plate-shaped workpiece 12 , for example in the form of a sheet metal, a preferably stationary processing device 21 is provided which has a punch 14 and a die, not shown in detail. Alternatively, a laser stamping machine can also be used, in which a laser processing head is arranged adjacent to the punch 14 . The workpiece 12 to be processed rests on the workpiece carrier 16 during workpiece processing. The workpiece 12 is held during machining by means of a holding device 17, preferably comprising a gripper 18, and can be moved relative to the punch 14 along the X axis of the workpiece plane (X / Y plane) by means of a conventional linear drive 19 indicated by an arrow. direction, the workpiece 12 can be moved along the Y direction of the workpiece plane in that the workpiece carrier 16 is relati...

Abstract

The invention relates to a method for the state control of a vacuum aspirator of a gripping device, each vacuum aspirator having a suction element and the suction element being actuated by means of avalve, wherein at least one suction of the gripping device is achieved The plate and the inspection device including the plurality of inspection devices are oriented relative to each other such that each vacuum aspirator is opposed to the inspection device disposed in the initial state. In order to inspect the suction element, the suction element is brought into contact with the inspection deviceand the vacuum aspirator is vacuum-loaded, or in order to inspect the valve, the valve is vacuum-loaded and the vacuum aspirator is brought into contact with the inspection device of the inspection device, in order to separate The suction element or the at least one valve is inspected, and as long as a change with respect to the initial state is detected on the inspection device, a signal is output by each inspection device of the inspection device.

Description

technical field [0001] The invention relates to a method and a device for condition monitoring (check control) of a vacuum suction device of a gripping device, which is subjected to a vacuum for gripping workpieces. Background technique [0002] From EP 1 967 301 A1 a machine assembly with a processing device for processing plate-shaped workpieces and a handling device for processing products is known. The processing machine is used for processing plate-shaped workpieces, in particular sheet metal. It is preferably provided here that punching and / or cutting processes are carried out. For handling workpieces, handling devices include gripping devices. The gripping device has one or more suction plates, wherein a plurality of vacuum suction devices are arranged on each suction plate. To pick up the workpiece, the vacuum cleaner is brought into contact with the workpiece. Subsequently, vacuum is applied, whereby the workpiece is gripped by the vacuum suction. Subsequently,...
