Control Method for Reducing Yarn Breakage on Spinning Frame

The invention discloses a control method for reducing broken ends of yarns of a spinning frame. The control method is characterized by comprising a starting step, a step for spinning small yarns, a step for spinning medium yarns, a step for spinning large yarns, a yarn feeding step and a high-speed halfway stopping step. When a fan is started, a ring plate moves upwards to an initial spinning position and moves upwards continuously; the ring plate moves upwards to an appropriate spinning position; a main motor is operated at a low speed; the ring plate moves downwards to the initial spinning position from the appropriate spinning position; the spinning is carried out at a low speed; if the operating time is equal to Pd, the step for spinning the medium yarns is started; the ring plate moves upwards to the appropriate spinning position first and then moves downwards to the initial spinning position; an air ring can be opened in time; the wavelength of the air ring is shortened; the tension of the yarn is reduced, and the broken end rate of yarns when the small yarns are spun can be greatly reduced; in order to protect the ring plate motor, the operating time of the ring plate motor can be set to start five seconds later after the fan is started, and if an initial spinning position sensor is in malfunction, the ring plate motor can be stopped when moving upwards for five seconds at most.

Control Method for Reducing Yarn Breaks on Spinning Frame

The invention discloses a control method for reducing yarn broken heads of a spinning frame. The control method comprises a starting step, a small-yarn spinning step, a middle-yarn spinning step, a big-yarn spinning step and a doffing step; in the starting step, a fan is started while a steel collar plate moves up to an initial spinning position, and then the steel collar plate moves up from the initial spinning position till reaching a proper spinning position, and then a primary motor starts to run at low speed, the steel collar plate moves down from the proper spinning position to the initial spinning position and then runs at the low speed and spins, and if the running time is equal to Pd, the middle-yarn spinning step is started; the steel collar plate firstly moves up to the proper spinning position and then moves down to the initial spinning position from the proper spinning position; an air ring is timely opened, the wavelength of the air ring is shortened, the yarn tension is reduced, and the breaking rate of yarns during the small-yarn spinning process is greatly reduced; the steel collar plate motor can be protected; the running time of the steel collar plate motor can be set as 5 seconds after the fan is started; if a sensor is in fault at the initial spinning position, the steel collar plate motor moves up for at most 5 seconds and then stops.

Control method and device for reducing yarn breakage of spinning frame

The invention discloses a control method used for reducing broken yarn ends of a spinning machine. The control method comprises a starting step, a small yarn spinning step, a middle yarn spinning step, a large yarn spinning step and a yarn discharge step. The starting step is that a fan is started, a steel collar plate simultaneously moves upwards to the initial spinning position when the fan is started, then the steel collar plate can continue moving upwards from the initial spinning position, the steel collar plate moves upwards to the appropriate place spinning position, then a main motor begins to run at low speed, and the steel collar plate can move downwards from the appropriate place spinning position to the initial spinning position to run at low speed to spin. If running time is equal to Pd, the middle yarn spinning step begins, the steel collar plate can move upwards to the appropriate place spinning position and then moves downwards from the appropriate place spinning position to the initial spinning position, an air ring is opened timely, wavelength of the air ring is shortened, yarn tension is reduced, and broken yarn end rate in spinning small yarns is remarkably reduced. A steel collar plate motor can be protected, and running time of the steel collar plate motor can be arranged 5 seconds after the fan is started. If an initial spinning position sensor is in fault, the steel collar plate motor moves upwards 5 seconds at most to be stopped.

Control method and device for reducing yarn breakage of spinning frame

The invention discloses a control method for reducing broken ends of yarns of a spinning frame. The control method comprises a starting step, a small yarn spinning step, a medium yarn spinning step, a large yarn spinning step and a doffing step, wherein in the starting step, a fan is started, at the same time, a ring rail goes upwards to a spinning beginning position, and then continues going upwards from the spinning beginning position; the ring rail goes upwards to a proper spinning position, and then a main motor begins to run at a low speed; the ring rail goes downwards from the proper spinning position to the spinning beginning position, and then the ring rail runs at a low speed for spinning; if the running time is equal to Pd, the medium yarning spinning step is performed; firstly, the ring rail goes upwards to the proper spinning position, then the ring rail goes downwards from the proper spinning position to the spinning beginning position, an air ring can be opened in time, the wave length of the air ring is shortened, the yarn tension is reduced, and the end breakage rate of the yarns is substantially reduced when small yarns are spun; a ring rail motor can be protected, the running time of the ring rail motor can be set for 5 seconds since the fan is started, and if a sensor at the spinning beginning position malfunctions, the ring rail motor stops after going upwards for at most 5 seconds.

A control method and device for reducing yarn breakage of spinning frame

The invention discloses a control method for reducing yarn breakage of a spinning frame. The control method comprises the starting step, the step of spinning the small yarn, the step of spinning the medium yarn, the step of spinning the large yarn and the step of doffing. A blower is started, a steel collar plate is upwards moved to the initial spinning position while the blower is started, and continuously moved upwards from the initial spinning position. The upward time is Pe. The steel collar plate is upwards moved to the suitable spinning position, and then a main motor is operated in the low speed, the steel collar plate is downwards moved from the suitable spinning position to the initial spinning position. The downward time is Pf. The steel collar plate is upwards moved to the suitable spinning position first, and downwards moved from the suitable spinning position to the initial spinning position. An air ring is opened in time, the wave length of the air ring is shortened, the yarn tension is reduced and the breakage rate of the yarn is greatly reduced during the moment of spinning the small yarn. In addition, the motor of the steel collar plate can be protected, and the operation time of the motor of the steel collar plate is set as 5 seconds from the blower start. If a sensor on the initial spinning position does not work, the motor of the steel collar plate is stopped after at most 5 seconds of upward movement.
