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 failure prediction in a packaging machine is disclosed. The method includes recording data values ​​associated with movement of an independently movable object along a track in the packaging machine; determining a distribution of data values; calculating a measure of a central tendency of the data values ​​in the distribution; calculating a quantitative measure of the shape of the distribution; associating a measure of the central tendency with said quantified measure of the shape as coupled sets of condition parameters; determining a degree of dispersion of the coupled sets of condition parameters associated with multiple motion cycles of an independently movable object and comparing the degree of dispersion with a dispersion threshold, or determining a trend of the degree of dispersion over time, to perform the fault prediction.

Description

technical field [0001] The present invention generally relates to the field of condition monitoring. More specifically, the present invention relates to a method of failure prediction in a packaging machine with independently movable objects, and an apparatus for predicting failures in such packaging machines or in related systems for producing sealed packages. Background technique [0002] Condition monitoring of machine components in production lines, such as in the manufacture of sealed packs in filling and packaging machines or related systems, is essential to ensure the required functionality and failure prediction over time. Monitoring deformation in the movement of machine components is an important part of achieving desired functional control and preventing wear-related failures. Deformation analysis of eg vibration in bearings is an important part of industrial predictive maintenance programmes, enabling wear and damage to be detected and repaired before machine fa...
