Single spindle drive type twisting frame

Abstract

This machine is obtained by installing a load detecting means for detecting the load on a driving motor, a voltage detecting means for detecting the fluctuation in a power source voltage for feeding an electric power to the driving motor and a motor controller for monitoring the load fluctuation detected with the load detecting means, monitoring the fluctuation in the power source voltage from the voltage detecting means and detecting the presence or absence of the yarn breakage of each yarn to be twisted from the fluctuation both in the load and the power source voltage in the single spindle driving type twist texturing machine equipped with the driving motor for each spindle unit for imparting twists to the yarn. To provide a single spindle driving type twist texturing machine capable of preventing malfunction of the detection of yarn breakage at the time of fluctuation just after starting the twist texturing or on the side of a power source voltage.

Description

technical field [0001] The present invention relates to a twisting machine such as a two-for-one twister or a ring spinning machine, and more particularly, to a single-spindle-driven twisting machine capable of stopping each spindle when the spindle is driven to break. Background technique [0002] Conventionally, two-for-one twisters have adopted a structure in which a plurality of spindles of the twisting device are arranged, and the twisting device is provided with a winding device above the spindle device. [0003] The spindle device consists of a fixed disk for supporting the yarn feeding package, a rotary disk arranged under the fixed disk for twisting the fed yarn, and a drive motor to rotate the rotary disk. [0004] The yarn of the yarn feeding package supported on the fixed disk is opened and stretched by the tensioner at the same time, then passes through the axis of the yarn feeding package and protrudes radially outward from the rotating disk, forming a balloon ...

Problems solved by technology

[0008] However, even when no end breakage occurs, the load on the drive motor will fluctuate when the balloon is not stabilized when the spindle unit is started, or when the balloon is disturbed due to voltage fluctuations from the commercial power supply when the spindle unit is stopped momentarily. Therefore, even if the twisting device is performing the twisting process normally, it is inevitable that there will be an erroneous judgment of stopping the drive motor as the end breakage occurs.
