Embodiment Construction

[0025] For a general description of an embodiment of a vacuum system 10 for transporting objects, reference is initially made to figure 1 .

[0026] will now refer to figure 1 An embodiment of the invention is described, wherein details of the embodiment corresponding to the above description of the vacuum system will be given by the previous figure 1 The corresponding reference numerals used in .

[0027] The vacuum system 10 comprises a vacuum generator 3 driven by a flow of compressed air via a first on / off valve 1 or other mechanism for controlling the flow of compressed air, wherein the vacuum generator 3 being part of the vacuum system 10 is arranged in conjunction with One or more vacuum grippers 6 also included in the vacuum system 10 are fluidly connected to supply vacuum to the vacuum grippers 6 due to the flow of compressed air to the vacuum generator 3 . The vacuum system 10 comprises a second valve 2 arranged to be activated (normally opened) and supply compres...

Abstract

The invention relates to controlling a vacuum system comprising a vacuum generator. A method for controlling a vacuum generator in a vacuum system for transportation of objects, the vacuum system comprises a vacuum generator driven by a compressed air flow via a first on/off valve, a second valve, which is arranged to supply compressed air into the vacuum system, one centralized pressure sensor used for monitoring a system pressure inside the vacuum system and for adaptive blow-off; and a vacuum system controller, wherein if the on/off valve is not flowing air to the vacuum generator, the vacuum system controller indicates a state of no vacuum generation, and the second valve is activated, allowing an amount of compressed air to flow into the vacuum-system for blow-off, blow-off is terminated and excessive air injected into the system is released through the vacuum gripper means, analyzing pressure propagation following blow-off for calculating a duration of when the vacuum system is being fully pressure-equalized in parts of the vacuum gripper means by using a compensation factor.

Description

technical field [0001] The invention relates to a method of controlling a vacuum system comprising a vacuum generator and a controller for a vacuum system comprising a vacuum generator driven by compressed air in order to generate a negative pressure suitable for suction cups or similar devices . Background technique [0002] The present invention relates generally to material handling systems, and more particularly to a material handling system for controlling a vacuum generator for a suction cup of a material handling system that engages an object and substantially passes through a vacuum comprising a vacuum generator and a suction cup. The operation of the system is hermetically sealed. It is known to provide a material handling system comprising suction cups or the like adapted to move and lift and move an object such as a substantially flat object or panel or the like into a desired position. The suction cup can be moved to engage the object, and the vacuum generator ...
