Title (EN) OPTICAL POSITION MONITOR FOR KNITTING MACHINES
(FR) DISPOSITIF DE CONTROLE DE POSITION OPTIQUE POUR MACHINES A TRICOTER
Abstract:
(EN) An optical position monitor for determining the position of a latch needle (104) in a knitting machine is provided that comprises: at least one fiducial (102) at a known fixed location on the body of the latch needle; a fiducial imager that produces at least one optical image (262) of the at least one fiducial on at least one light sensitive surface (260) wherein the at least one optical image changes with changes in position of said at least one fiducial; and a controller that receives at least one signal responsive to the changes in the at least one image and uses the at least one signal to determine the position of the at least one fiducial (102) and thereby of the latch needle (104).
(FR) Cette invention concerne un dispositif de contrôle de position optique qui permet de déterminer la position d'une aiguille à crochet (104) dans une machine à tricoter. Ce dispositif comprend les éléments suivants: au moins un repère de centrage (102) qui se trouve en un endroit fixe et connu sur le corps de l'aiguille à crochet; un système d'imagerie de ce repère qui va produire une ou plusieurs images optiques (262) du ou des repères sur au moins une surface sensible à la lumière (260), cette image optique se modifiant en fonction des changements de position du ou des repères; et enfin, une unité de commande qui va recevoir au moins un signal en réponse aux modifications des images, et utiliser ce signal afin de déterminer la position du repère (102) et, partant, de l'aiguille à crochet (104).
