Description

Roll tail detection device and spider Technical Field The application relates to the technical field of glass fiber cloth production equipment, in particular to a tail winding detection device and a connection device. Background In industrial production, roll-like materials such as paper, film, metal foil, textile and the like are widely used. When the coiled materials are continuously supplied to the production flow, automatic identification of the tail of the coiled materials becomes a key link for ensuring production continuity, improving production efficiency and saving materials. Traditionally, detection of roll ends has relied on manual methods. The manual detection has a plurality of defects such as low efficiency, workers need to pay attention to the use condition of coiled materials at any time, and the tail state of the coiled materials is difficult to accurately capture on a production line running at a high speed. With the development of technology, automatic identification technology is applied to the field of tail detection gradually. For example, the photoelectric sensor simply based on the detection technology of the photoelectric sensor can judge the tail position of the coil according to the change of the shielding light of the coil by emitting and receiving light. However, this approach requires high light transmittance, color, and surface flatness of the web. When the color of the coiled material is deep or the surface is rough and uneven, the light reflection or scattering condition is unstable, the sensor signal is easy to fluctuate, and the detection result is inaccurate. The detection accuracy of the photoelectric sensor is greatly compromised by materials that absorb light strongly, such as black plastic films. Therefore, a more efficient, accurate and adaptive automatic tail recognition scheme is needed to meet the continuous improvement of industrial production.
