If, on the other hand, the pulse duration is too long and the air flow is too high, the blowing process can result in the projected object or also surrounding objects being blown out of the associated storage device and reproducible storage of the objects cannot be carried out.

Embodiment Construction

[0029] These two are attached figure 1 with 2 The vacuum gripping device 1 shown in FIG. 4.

[0030] The suction gripper 3 , for example a suction cup or a suction cup, delimits a suction chamber 5 , which is generally open on the working side 6 of the suction gripper 3 and is in fluid connection with a channel through the working line 4 .

[0031]The working line 4 can be, for example, a rigid line or an air-conducting channel configured in any desired manner in a rigid body. The design as a flexible hose line is particularly advantageous, since it allows a particularly variable laying. Typical lengths of working lines are between 0.03 and 1.5 m. Depending on the application, it is also possible to completely dispense with the working line 4 .

[0032] The control valve arrangement 7 of the vacuum gripper 1 is coupled to the suction gripper unit 2 . In this way, the suction gripper 3 and more precisely its suction chamber 5 are in fluid connection with the control valve...

Abstract

A method is proposed for operating a vacuum gripping apparatus (1) which has a suction gripper unit (2) having at least one suction gripper (3). The suction gripper unit (2) is connectable selectively, via a control valve device (7), to a vacuum source (V) or to an overpressure source (P) that generates an ejector pulse in the suction gripper (3). The ejector pulse is generated depending on the actual pressure that is established in the suction gripper unit (2) after connection to the overpressure source (P). Also proposed is a vacuum gripping apparatus (1) suitable for carrying out this method, which has a pressure measuring device (23) for sensing the actual pressure and an electronic control unit (12) which serves to actuate the control valve device (7) and which communicates with the pressure measuring device (23).

Description

technical field [0001] The invention relates to a method for operating a vacuum gripping device (Vakuum-Greifvorrichtung), which comprises a suction gripper unit with at least one suction gripper (Sauggreifer), which can be coupled to it via The control valve device is optionally connected to a vacuum source that causes a negative pressure in the suction gripper or to an overpressure source that generates throw pulses (Abwurfimpuls) in the suction gripper. [0002] The invention furthermore relates to a vacuum gripping device, which can be operated in particular in the aforementioned sense and which comprises a suction gripper unit with at least one suction gripper, which can be optionally communicated via a control valve device coupled thereto A vacuum source that causes a negative pressure in the suction gripper or is connected to an overpressure source that generates a throw pulse in the suction gripper, wherein an electronic control unit is present for actuating the contro...
