Abstract
A textile machine (4) for a weaving loom having an input shaft which is coupled to a weaving loom. The drive mechanism is driven by the input shaft to move frames or collars of the weaving loom through a sequence of predefined positions. The electronic control device is programmed to monitor the change in position of each frame or collar during each step of the predefined sequence of positions and to count the number of times each frame or collar reproduces a particular configuration.
Claims14
A textile machine for a weaving loom, comprising:
- an input shaft configured to be coupled to a weaving loom;
- a drive mechanism actuated by the input shaft and configured to move frames or collars of the weaving loom through a predefined sequence of positions, said drive mechanism having at least one mechanical output component configured to be coupled to one of said frames or collars of the weaving loom;
- an electronic control device including a processor and a computer memory,
- wherein said control device is programmed to monitor the change in position of each frame or collar during each step of the predefined sequence of positions and to count the number of times each frame or collar reproduces a particular configuration,
- wherein the control device is further programmed to automatically calculate a cumulative damage index for at least some of the textile machine components, defined as the state of wear of the component relative to a reference state,
- and wherein the control device is further programmed to automatically compare the damage index, for at least some of the textile machine components, to a predefined value and to update a state variable representing the comparison.
A method for operating a textile machine for a weaving machine, said textile machine comprising:
- an input shaft, configured to be coupled to a weaving loom;
- a drive mechanism, actuated by the input shaft and configured to move frames or collars of the weaving loom in a predefined sequence of positions, said drive mechanism having at least one mechanical output component configured to be coupled to one of said frames or collars of the weaving loom;
- an electronic control device including a processor and a computer memory,
- wherein the method comprises monitoring the change in position of each frame or collar of the weaving loom during each step of the predefined sequence of positions and counting the number of times each frame or collar reproduces a particular configuration, and wherein the method further comprises, for at least a portion of the textile machine components:
- calculating a cumulative damage index defined as the state of wear of the component relative to a reference state,
- comparing the damage index to a predefined value;
- updating a status variable representing the comparison.
