Title:
織機に緯糸を挿入するサイクルを監視する方法
Document Type and Number:
Japanese Patent JP4546649
Kind Code:
B2
Abstract:
A method for monitoring the cycle of the weft insertion into a weaving machine. The weft yarn passes a yarn brake and a yarn force sensor and the force acting on the weft yarn is measured in a known fashion and the reaction force of the yarn is converted by a pressure sensitive element into an electrical signal. The electrical signal outputted by the yarn force sensor is electronically amplified in an evaluation unit, is evaluated and is transmitted to an indicator informing the operator of the development of the weft insertion and of disturbances and corrections. For this purpose, the evaluation unit is connected via a data line with a machine control unit. Evaluation unit is supplied with time signals from the machine control unit associated with further machine functions participating at the weft insertion, e.g. the momentary angular position of the main shaft of the machine. The machine control unit receives monitoring signals of the yarn force evaluation via the data line, e.g. for immediate stoppage in case of a yarn breakage occurring during the weft insertion, or to activate a machine related alarm system in case of a disturbance needing the interference by an operator.
