Definitions

  • the present invention relates to a cost effective yarn breakage monitoring system and more specifically relates to a reliable means and method of identifying yarn breaks in multi-spindle machines to alert human operators responsible for mending them on-time and in real time.
  • the present invention provides for a yarn breakage- monitoring system wherein the workers are equipped with distributed client-devices to which the server in turn relays yarn breakage information and the workers responsible for that spindle are alerted to the problem of yarn breakage, to mend it at the earliest.
  • the movement of the overhead traveling cleaner is typically jerky, swaying and of non-uniform speed, its path of travel being about a meter away from the yarn-strands being monitored.
  • the kind of sensors described in these two patents would perform highly unreliably in such an environment.
  • the present invention proposes to overcome these limitations by the use of a camera that involves thousands (or millions) of sensors arranged in a two-dimensional array. Each sensor captures a picture element (pixel), and the array of pixels adds up into a complete image. While cameras involving high resolution are available, these are generally more expensive. It is more advantageous to use optical arrangements, such as those involving a plurality of lenses, to 'bring the objects closer', thereby magnifying them. Alternatively, any of the known systems of magnifying the image using software may be used. While a number of methods are used in commercially available off-the-shelf devices, the interested reader may refer to US 7,202,888 and US 5,231,519 which describe specific methods of achieving this.
  • the traveling camera in the present invention would capture images at distinct instants of time so that successive frames capture advancing sets of spindles traversed by the movement. While blurring of images due to shake of camera can be compensated as described above, uneven speed and orientation of the camera makes it difficult to identify the exact position of the yarn (or yarn-break) that is being captured on the image. It is proposed to overcome this limitation by ensuring that successive images are formed by overlapping frames, so that by the overlapping (common) areas of successive images, a larger continuous image is "stitched" together. Techniques of achieving this are well known to any person familiar with the prior art. The attention of the reader is drawn to US 5,611,033, US 6,104,840 and US 7,184,091 as illustrations of this.
  • the machines generally have a dark or matte background behind the yarn strands being monitored for breaks, as these facilitate human operators patrolling to monitor the spindles. It is advantageous to mark this surface with machine-readable indicia that are captured in the camera images. This will facilitate the stitching together of successive images to create a composite image, thereby ensuring that the location of a yarn-break is identified without error.

Abstract

L'invention concerne un système de contrôle rentable de rupture de fil et spécifiquement un moyen et un procédé fiables d'identification de ruptures de fil dans des machines mulltibroche permettant d'informer sur l'instant et temps réel le personnel opérateur chargé d'y remédier. On décrit plus particulièrement un système et un procédé d'identification de rupture de fil qui consiste à utiliser un seul module d'exploration (5) traversant plusieurs machines, comprenant chacune plusieurs broches (6). L'avantage de cette invention est que le personnel est équipé de dispositifs clients répartis auxquels le serveur à son tour transmet des informations de rupture de fil. Le personnel responsable de la broche concernée est informé d'une rupture de fil et peut y remédier dans les plus brefs délais.
