Electromagnetically separated and closed yarn storage device and yarn detection method thereof

Abstract

The invention discloses an electromagnetically separated and closed yarn storage deice and a yarn detection method thereof. The yarn detection method comprises the following steps of: providing the yarn storage device which is provided with an electromagnetic coil, a first drive shaft, a second drive shaft, a drive disc, a driven disc, a yarn storage wheel and light sensors; winding yarns on the edge of a yarn storage nail of the yarn storage wheel; when only part light signals are interrupted by the yarns or the yarn storage nail, expressing that the yarns are insufficient and outputting a start signal to switch on the electromagnetic coil for making the electromagnetic coil excite to joint the drive disc and the driven disc so that the rotating power of the first drive shaft is transferred to the second drive shaft to drive the yarn storage wheel to perform a yarn storage action; and when all light sensors used for receiving do not receive the light signals, expressing that the yarns wound on the yarn storage wheel are excessive and outputting a close signal to interrupt the excitation of the electromagnetic coil to separate the drive disc from the driven disc so that the rotating power transferred from the first drive shaft to the second drive shaft is interrupted to drive the yarn storage wheel to stop the yarn storage action. The device has a simple structure and low power consumption.

Description

technical field [0001] The invention relates to a yarn storage device and a yarn detection method thereof, in particular to an electromagnetic clutch yarn storage device and a yarn detection method thereof. Background technique [0002] With the continuous development of the textile industry, more and more textile machines must have the demand for supplying irregular yarns to adapt to factors such as the weaving of fabric patterns and fabric tension, so as to meet the demand for yarn supply. In particular, the strip-type yarn storage device does not need an active motor, but uses the strip equipped on the knitting machine as a power source, which simplifies the mechanism, reduces the volume, and reduces the cost. [0003] In order to make the yarn storage device suitable for computer jacquard machines with irregular yarn feeding, the industry has developed an electronic yarn storage device, which installs an electric motor in the yarn storage device, and uses the yarn detect...

AI Technical Summary

Problems solved by technology

The sensor uses reflective sensing, it is difficult to accurately detect the yarn on the drum storage (storage wheel), and the first and second circumferential parts of the storage surface are specially constructed, resulting in an increase in manufacturing costs
