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

[0033] Examples such as figure 1 , figure 2 , image 3 As shown, a control method and device for reducing yarn breakage in spinning frame, the device includes a PLC controller and a full bobbin sensor 8, peach disc 2, position sensor 5, and rotor 7 arranged on the spinning frame , blower fan 9, main motor 10 and ratchet support pawl, in-place sensor 5 and rotor 7 are arranged on the spinning frame around peach disc 2, and full bobbin sensor 8 is arranged on the position equivalent to 90-95% of the total amount of yarn on bobbin 1. position, a signal sampler 6 is fixed on the peach plate 2,

[0034] 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. After rotating until the tip of the peach 3 contacts the rotor 7, the ring plate completes a cycle of spinning steps; when the signal sampler 6 cooperates with the position sensor 5 for induction, the position sensor 5 outputs ...

Abstract

The invention discloses a control method for reducing the spinning yarn breakage of a spinning machine. The method includes the start step, the small yarn spinning step, the intermediate yarn spinning step, the large yarn spinning step and the doffing step. In the large yarn spinning step, when the amount of yarn on a bobbin reaches 90% to 95% of the total spinning amount, a full bobbin sensor outputs a full bobbin signal and conducts spinning at a low speed, if the running time is equal to Pg, the doffing step is executed, and the existing position of the full bobbin sensor is appropriately moved downwards; in other words, when the amount of the yarn reaches 90% to 95% of the total spinning amount, the full bobbin sensor sends out a signal, spinning is conducted at the low speed, when the yarn reaches the full bobbin position after the low-speed running is conducted for the time Pg, doffing is executed, and the breakage rate of the yarn is effectively decreased.

Description

[0001] The present invention is a divisional application of application number 2013100333170, application date January 29, 2013, and title of the invention "control method and device for reducing yarn breakage in 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 in 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 the yarn breakage rate ...
