Abstract
A management method for fiber-processing and a management apparatus thereof, which can detect the occurrences of the selected monitoring events by monitoring the occurrences, can investigate the causes of the occurrences of the events by treating the events so that the factors of the occurrences of the problems can be easily determined whether they are attributable to the problem of the fiber-processing machine itself or the problem of supplied yarn, and can promptly accurately present countermeasures against the problems.
Claims36
A management method for fiber-processing comprising the steps of:
- (a) selecting a plurality of monitor needed events including at least a tension variation of a yarn during fiber texturing in order to manage processing conditions of the yarn which is wound up as a yarn package in a fiber forming process, wherein the tension variation is identified as a large variation of a tension level of the texturing yarn or a tension variation having an abnormal behavior different from the behavior under normal processing,
- (b) supplying the yarn to at least one position of a fiber texturing machine,
- (c) monitoring the selected monitoring events,
- (d) detecting an occurrence of the monitoring events,
- (e) chronologically storing the occurred monitoring event with data to identify an occurred moment of the monitoring event for each yarn package during fiber-processing and/or for each position of the fiber texturing machine during fiber-processing and
- (f) managing the fiber-texturing process or the fiber texturing machine by the stored data.
A management apparatus for fiber-processing comprising:
- a monitoring event detector placed in each position of a fiber texturing machine for detecting monitoring events selected so as to monitor processing conditions of texturing yarn under processing in each position of a fiber texturing machine, and the monitoring event detector further comprises at least a tension detector placed at a reference point for detecting at least a tension variation of the moving yarn tension by touching the moving yarn, wherein the tension variation is identified as a large variation of a tension level of the texturing yarn or a tension variation having an abnormal behavior different from the behavior under normal processing,
- a scanning device for scanning every position of the fiber texturing machine to be monitored in order to detect an occurrence of the monitoring events by the monitoring event detector in each position, and
- a management device for chronologically storing the detected result of the monitoring events during fiber-processing by yarn package or by position of the fiber texturing machine together with data to identify the occurred moment of the monitoring events while a yarn supplied from the yarn package is processed.
