A structure for focusing and / or restraining the size of a correlation beam is arranged on a transmitting window and a receiving window of a photoelectric transmitting tube and a photoelectric receiving tube on the inner sides of two arms of a monitor frame, a monitor light path is arranged at the position close to a yarn guide hole, a sliver monitor and a spindle position controller are combined into a whole, and the spindle position controller is installed on a yarn guide plate.

Description

technical field [0001] The invention relates to the field of textile machinery informatization, in particular to a device and system for online real-time monitoring of spun yarns of a ring spinning machine. Background technique [0002] The real-time monitoring of the spinning sliver of the ring spinning frame is the collection and application of the basic information of spinning information, the auxiliary technology for monitoring the spinning status and quality, improving the value of the car and production efficiency, and also the basis for improving the management of the spinning production spindle position. important means. [0003] For the real-time monitoring of ring spinning, the typical application is the end detection of spinning frame. The technical solution of end-break detection was first proposed more than 40 years ago. Since then, many manufacturers in the world have launched related products and have been applied in a small amount. In recent years, with the...

Problems solved by technology

Use electromagnetic or photoelectric sensors to detect the speed of the traveler rotating at high speed on the steel ring, and use excitation electromagnetic induction or light reflection induction to detect the motion information of the detected traveler, which is limited by the installation of the sensor on the ring plate position, and give way to the necessary joint operation space, the traveler motion signal that the sensor can detect is a weak analog signal, which requires steps and links such as microelectronic information sensing, signal amplification, transformation, transmission and processing, etc. The signal processing conversion process and circuit are complicated, which makes the system configuration cost higher, which limits the popularization and application of the broken end detection device

And the traveler as the detection object is the indirect carrier of the spinning speed, so the information related to the sliver body cannot be collected; at the same time, the process change of the diameter of the steel ring will change the way of detecting the rotation information of the traveler and affect the broken end detection device The use of electromagnetic sensors will also generate magnetization and magnetic field force on the traveler, which will affect the roundness of the balloon rotation; the space occupied by the broken end detection device on the outside of the ring plate will also adversely affect the work of the subsequent automatic jointing machine

[0005] In the prior art, there are also some end-break detection technical solutions for detecting yarn sliver at the spinning section or yarn guide hook, or non-real-time roving detection, which can only detect the end-break signal without the spindle speed signal; or the sensor can detect the yarn breakage signal. A weak analog motion signal needs to go through steps and links such as microelectronic information sensing, signal amplification, transformation, transmission and processing, which complicates the signal processing and conversion process and circuit, making the system configuration cost higher, which limits the broken end detection device popular application of
