Abstract
A method for monitoring contact of a rotating component of a textile machine, in particular of a clothing roller of a card, for example a card cylinder, with a further component of the textile machine. The two components are connected to an electrical power source, but are normally electrically isolated from each other, and only in the case of a contact between the two components, a short-circuit is generated, which is detected by the monitoring device. The duration of individual short-circuits per time unit (T) is detected and summed up so as to form a total duration (t) of all short-circuits per time unit (T).
Claims15
A method for monitoring contact between a rotating component of a textile machine and another component of the textile machine, comprising:
- connecting the rotating component and the other component to a common electric power source, wherein the components are not in contact and are electrically isolated during normal operations of the textile machine;
- with a monitoring device, detecting short circuits that are generated by contacts between the rotating component and the other component;
- and
- wherein for multiple short circuits, the detecting step includes summing total duration time (t) for all of the detected short circuits over a defined unit of time (T) to define a total duration of short circuits per unit of time.
A textile machine such as a carding machine, comprising:
- a rotating component;
- another component disposed with a spacing opposite from the rotating component;
- an electric power source, the rotating component and other component connected to the electric power source but maintained electrically isolated from each other in normal operations of the textile machine;
- wherein upon contact of the rotating component and the other component, a short circuit is generated;
- a monitoring device configured to detect duration of multiple individual generated short circuits over a unit of time (T) and to sum the individual durations into a total duration time (t) per the unit of time (T).
