Problems solved by technology

Traditional equipment still in use in the market, such as FA502, FA503 and A513, etc., mainly use AC contactors to control the spinning process of the entire spinning frame. control
In order to reduce the yarn breakage rate of the spinning frame, at present, frequency converters are generally used to control the realization. However, due to the large number of old spinning frames mentioned above in the textile industry, these spinning frames are transformed. The frequency converter of each device is combined with the The cost of PLC is nearly 10,000 yuan. It is very difficult for many textile enterprises using old equipment to realize this method of control, which affects the product quality and output of these enterprises.
On the other hand, flying flowers are easy to block the heat dissipation system of the frequency converter, which is the disadvantage of the old type of spinning frame controlled by the frequency converter, and it is also the main reason that the frequency converter is easy to burn out or even cause a fire after being used for a long time

Embodiment Construction

[0040] Examples such as figure 1 , figure 2 , image 3 As shown, a control method and device for reducing yarn breakage on a spinning frame, the device includes a PLC controller and a full bobbin sensor 8, a peach plate 2, a position sensor 5, a rotor 7, and a fan arranged on the spinning frame 9. The main motor 10 and the ratchet support claw, the position sensor 5 and the rotor 7 are arranged on the spinning frame around the peach plate 2, and the full bobbin sensor 8 is arranged at a position equivalent to 90-95% of the total amount of yarn on the bobbin 1. A signal sampler 6 is fixed on the peach plate 2,

[0041] The peach plate 2 has a peach tip 3 and the lowest end 4 of the peach plate. When the peach tip 3 contacts the rotor 7, the ring plate starts to go down. Then rotate until the tip of the peach 3 is in contact with the rotor 7, and the ring plate completes a cycle of spinning steps; when the signal sampler 6 cooperates with the position sensor 5 for induction,...

Abstract

The invention discloses a control method for reducing yarn break of a spinning frame. The control method comprises the following steps of starting, namely starting a fan and ensuring a ring plate goes up to an initial spinning position and then continuously goes up from the initial spinning position; when the ring plate goes up to a proper spinning position, ensuring that a main motor begins to run at a low speed and the ring plate goes down to the initial spinning position from the proper spinning position; running at a low speed for spinning, and when running time is equal to Pd, outputting a signal by using a proper position sensor and entering a medium yarn spinning step. The ring plate goes up to the proper spinning position and then goes down to the initial spinning position from the proper spinning position, so that ballooning can be timely opened, the wavelength of the ballooning is shortened, the yarn tension is reduced and the breakage of yarns in the small yarn spinning process is greatly reduced; the running time of a ring plate motor can be set to 5 seconds after the fan is started and the ring plate motor goes up for 5 second at most and stops if an initial spinning position sensor fails.

Description

[0001] The present invention is a divisional application with the application number 2013100334239, the application date is January 29, 2013, and the title of the invention is "a control method and device for reducing yarn breakage of spinning frame". technical field [0002] The invention relates to a control method for the spinning process of a spinning frame, which is suitable for the spinning frame, in particular to a control method and a device for reducing yarn breakage of the spinning frame, and belongs to the technical field of textiles. Background technique [0003] In the textile industry, the spinning frame is usually used to spin on the bobbin 1, and reducing the breakage rate of the spinning frame during spinning is the goal that the industry has been pursuing. Traditional equipment still in use in the market, such as FA502, FA503 and A513, etc., mainly use AC contactors to control the spinning process of the entire spinning frame. control. In order to reduce t...
