摘要： PURPOSE:To prevent damage of yarn before it occurs by detecting the ballooning speed of reeled yarn, converting the detected result to electric voltage and detecting the change of yarn feed by electrical signal treatment by comparison of the converted electric voltage with a threshold value and change rate of electric voltage. CONSTITUTION:Yarn 1 knotted between two yarn feeding materials 21 and 22 is reeled from one yarn feeding material 21 in the direction of winding axis and guided through a ring-shaped detector 3 consisting of a projector 6 and a receptor 7 opposingly arranged in an introducing hole 31 and also used as a yarn guide to a length measuring storage device 4. In the detector 3, a pulse signal proportional to the ballooning speed is generated, sent to a signal treating part 20, the pulse signal is converted to electrical voltage, compared with a threshold value corresponding to the change of yarn feeding or difference between the detected ballooning speed and that of the previous time is compared with the threshold value of amount of change to the detect change of yarn feeding.

摘要： PROBLEM TO BE SOLVED: To control the misoperation of a loom on the basis of the misdetection of a sensor due to disturbance. SOLUTION: This loom, containing plural sensors, one or more controllers for controlling target members with the output signals of one or more sensors, and monitors for outputting abnormal signals which mean abnormal states, when the changes in the output signals of two or more sensors are simultaneously inputted. The abnormal signals generated in the monitors are utilized for the execution of a prescribed operation, such as the display of the misdetection, a treatment operation ignoring the output signals of the sensors, or an automatically or manually commanded operation. Thereby, the controller misoperation caused by the effect of the disturbance on the sensors can be controlled as much as possible.

摘要： PROBLEM TO BE SOLVED: To automatically inspect the web of woven cloth precisely in response to various weave styles. SOLUTION: Light reflecting a finish condition of nondefective normal woven cloth is detected, and an electric output signal corresponding to a received amount of the light is produced as a reference signal pattern. The reference signal pattern is stored in relation to the weave style of the normal woven cloth. When inspecting the woven cloth to be inspected, the reference signal pattern corresponding to the weave style of the woven cloth to be inspected is read out and light reflecting a finish condition of the woven cloth to be inspected is detected. A measured output signal pattern corresponding to the received amount of the light is detected and the read out reference signal pattern and the measured output signal pattern are compared to determine whether the inspected woven cloth has a defect.
