Embodiment Construction

[0031] Fig. 1 mainly shows the control device 8 of the present invention. The control device 8 is used to control the machine, in particular the mobile machine elements 9 of the machine. For this purpose, the control device 8 determines the position calibration value X in the form of a position calibration value soll (n), where the position calibration amount X soll (n) is output to the regulating device 6 as the regulating calibration input quantity. The regulating device 6 controls the drive device 7 for driving the movable machine element 9 . The control device 8 here can be, for example, the control device of a crane, and the machine element 9 can be, for example, a carriage on the crane, which is movable along the boom of the crane and carries a crane hook for hanging the load via ropes. The position calibration quantity X describing the expected calibration position of the slide along the crane boom soll (n) is set as the expected adjustment amount of the adjustment ...

Abstract

The invention relates to a method and a control unit (8) for guiding the displacement of a displaceable machine element (9) of a machine, said method comprising the following steps that are carried out in the control unit (8): a) input of a travel displacement (Xv) that is to be carried out by the machine element (9) and an optimisation criterion (OpK); b) determination of a displacement profile (Xsollk(t)) using the travel displacement that is to be carried out by the machine element (9) and the optimisation criterion (OpK), c) determination of a target position variable (Xsoll(n)) by means of the displacement profile (Xsollk(t)), d) output of the target position variable (Xsoll(n)) to a controller (6) for carrying out the travel displacement of the machine element (9). The invention provides a simple method and a simple control unit (8) for optimising the guidance of the displacement of a displaceable machine element (9) of a machine. Said method and device permit a user to directly influence the optimisation of the travel displacement.

Description

technical field [0001] The invention relates to a method of guiding the movement of a movable machine element on a machine and a corresponding control device. Background technique [0002] When using machines such as machine tools, production machines and / or robots, it is often necessary to precisely position moving machine elements as quickly as possible without vibration. The punctual positioning of movable machine elements without vibrations is not possible with the aid of an adjuster for the moving machine shaft and simple predetermined calibration values, according to a predetermined travel path and predetermined dynamic parameters. When positioning machine elements, machine elements and / or loads experience unavoidable vibrations whose intensity depends on the current load, stroke length and set parameters such as shock, acceleration and speed. [0003] Especially when using production machines with loading and unloading devices in the form of high-bay warehouses or cr...
