Abstract
To enable malfunctions in the spindle drive motors of an individual-spindle-drive type textile machine in which each spindle has a rotating member (a false twisting member 5) for twisting yarn and a motor 15 for rotating the rotating member to be easily determined, a driver 30 for controlling the rotational speed of the motor 15 for each spindle and an alarm means 44 for notifying operators of a malfunction in the driver 30 are provided for each spindle.
Claims7
An individual-spindle-drive type textile machine comprising for each respective spindle cooperating rotating members for twisting yarn and a motor for rotating each rotating member, characterized in that the machine comprises a yam breakage detection mechanism for detecting yarn breakage during winding for each respective spindle, an alarm member provided for each respective spindle so as to be lighted, and a driver operative for controlling the rotational speed of each said motor for each respective rotating member and being operative for controlling a lighting state of said alarm member for each respective spindle, and in that said driver is operative to notify of at least two machine malfunctions, including yarn breakage, overload on any of said motors, and malfunction in the driver, by using a different lighting state of said alarm member corresponding with each respective malfunction.
An individual-spindle-drive type textile machine comprising for each respective spindle a false twisting apparatus comprising a pair of belts in contact with each other in such a way as to intersect each other, the textile machine also comprising, for each respective spindle, a motor for driving each of the belts, characterized in that the machine comprises a yarn breakage detection mechanism for detecting yarn breakage during winding for each respective spindle, an alarm member provided for each respective spindle so as to be lighted, and a driver for controlling the rotational speed of each said motor for each respective belt and for controlling a lighting state of said alarm member for each respective spindle, in that said driver is operative to notify of at least two machine malfunctions including yarn breakage, overload on the motor, and malfunction in the driver by using a different lighting state of said alarm member corresponding with each respective malfunction, and in that each said motor is immediately stopped when a detection signal from the yam breakage detection mechanism is input.
