Problems solved by technology

[0004] However, the known method and the known device for monitoring the deformation process have a major disadvantage: only the measurement signal curves exceeding the threshold value of the yarn tension are used for the analysis
In this way impermissible product limits have been reached leading to yarn quality defects
In addition, the known method and the known device have the further disadvantage that the identification of possible sources of interference depends only on the experience of the respective operator

Embodiment Construction

[0033] exist figure 1 An example of a texturing process for producing crimped yarn is schematically shown in . In this case, the deformation process is illustrated by a working station of the deformation machine. Such texturing machines usually have a number of processing stations in order to text a number of synthetic yarns in parallel. exist figure 1A processing station 1 and a bobbin station 2 of such a texturing machine are schematically shown in FIG. The processing station 1 has a creel 4 in which a supply bobbin 5 and a reserve bobbin 6 are held. The supply bobbin 5 supplies a yarn 3 which is conveyed in the processing station 1 for drawing and texturing. The yarn end of the supply yarn reel 5 is connected to the yarn start of the reserve yarn reel 6 via a yarn knot. This enables a continuous withdrawal of the yarn 3 after the supply bobbin 5 has been used up. The yarn end of the reserve yarn reel 6 is then connected to the yarn start of a new supply yarn reel 5 . ...

Abstract

The invention relates to a method and to a device for monitoring a texturing process for producing crimped threads. A thread tension is measured continuously on the textured thread and the measured signals of the thread tension are detected and analyzed continuously, at least in one time interval. According to the invention, for the early diagnosis of one of multiple sources of faults, a sequenceof the measured signals occurring in the time interval is analyzed by means of a machine learning program. To this end, the device according to the invention has a diagnostic unit, which interacts with the thread tension measuring device in such a way that the measured signals of the thread tension can be analyzed by means of a machine learning program in order to identify one of multiple sourcesof faults.

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for monitoring a texturing process for producing crimped yarns and a method for monitoring texturing according to the preamble of claim 11 process equipment. Background technique [0002] A method of this type and an apparatus of this type for monitoring a texturing process for producing crimped yarns are known, for example, from DE 196 14 027 A1. [0003] During the texturing of synthetic yarns, the production process is usually continuously monitored in order to achieve a possible, stable process control and, in particular, to maintain a stable product quality of the crimped yarn as much as possible. In this case, monitoring of the yarn tension on the moving yarn has proven effective in identifying process disturbances and / or product fluctuations. For this purpose, the yarn tension on the yarn is continuously measured in known methods and known devices for monitoring the texturi...
