Problems solved by technology

The assumption of constant rotational speed of a servo motor is severely constrained in the field of robotics, especially for objects or carts moving on tracks with independent and variable speed profiles
Methods are employed to accommodate variable speeds, but such solutions can also be complex to implement and are also associated with other limitations and undesirable assumptions

Abstract

A method of fault prediction in a packaging machine is disclosed. The method comprises registering data values associated with the motion of independently movable objects along a track in the packaging machine; determining a distribution of the data values; calculating a measure of central tendency of the data values in the distribution; calculating a quantified measure of a shape of the distribution; associating the measure of central tendency with said quantified measure of the shape as a coupled set of condition parameters; determining a degree of dispersion of a plurality of coupled sets of condition parameters associated with a plurality of motion cycles of the independently movable objects; and comparing the degree of dispersion with a dispersion threshold value, or determining a trend of the degree of dispersion over time, for fault prediction.

Description

technical field [0001] The present invention relates generally to the field of condition monitoring. More specifically, the present invention relates to a method of failure prediction in a packaging machine having independently movable objects, and a device for predicting failures in such a packaging machine or a related system for producing hermetically sealed packages. Background technique [0002] Condition monitoring of machine components in production lines (e.g. in the manufacture of hermetic packages in filling and packaging machines or related systems) is crucial to ensure the required functionality and failure prediction over time. Monitoring deformation as machine parts move is an important part of achieving desired functional control and preventing wear-related failures. Deformation analysis of, for example, vibrations in bearings is an important part of industrial predictive maintenance programs, enabling wear and damage to be detected and repaired before machin...
