Description

Broken yarn detection device for aramid yarn and yarn feeding machine
Technical Field
The invention relates to the technical field of optical fiber communication, in particular to an aramid yarn breakage detection device and a yarn feeder.
Background
Aramid yarn (Aramid Fiber) is a high performance synthetic Fiber commonly used to make high strength, heat, chemical and abrasion resistant materials. Aramid fibers have many excellent performance characteristics and are therefore widely used in a variety of fields including protective equipment, aerospace, automotive industry, fiber optic communications, and the like. Subunit cable production refers to the production process of manufacturing subunits in optical fiber communication cables. In fiber optic cables, a plurality of subunits are typically included, each subunit containing one or more optical fibers for transmitting data signals. Subunit cables are commonly used in long-haul data transmission and communication networks to provide high bandwidth and low signal attenuation performance.
In the production process of the subunit optical cable, the tension detection of the yarn feeding machine is used as a main means for detecting the continuity and yarn breakage of the aramid yarn. The current method mainly relies on tension detection of a yarn feeding machine to judge whether the aramid yarn is continuous or not. This means that if the tension detection fails, or if a part of the yarn after the yarn breakage of the aramid yarn is wound around the tension detection device, the yarn breakage cannot be detected in time. When a broken yarn condition is not detected in time, the discontinuous aramid yarn may be used further, resulting in production of an unacceptable cable product, which may cause quality problems and additional costs. Pay-off frames employing simple pay-off equipment generally do not have a tension detection function, which increases the difficulty in detecting broken yarns.
Therefore, an aramid yarn breakage detection device and a yarn feeding machine are needed to solve the above problems.

Through setting up a plurality of beam yarn mechanisms 200, aramid yarn broken yarn detection device can handle many aramid yarns simultaneously, has improved detection efficiency, can detect the broken yarn condition more soon.
Further, the yarn binding mechanism 200 in the present embodiment is movably mounted relative to the base 100, and the relative angle and the relative distance between the yarn binding mechanism 200 and the base 100 are adjustable. The paying-off of the aramid yarn can be accompanied by certain swinging or angle change, so that the setting can adapt to different paying-off conditions, and the angle or the distance can be changed. By the arrangement, the collecting path of the first yarn hole 210 can be kept within a proper angle and a proper distance all the time, and the broken yarn can be more accurately captured by the aramid yarn broken yarn detection device, so that the false alarm rate is reduced.
Further, the aramid yarn breakage detecting device in the embodiment further includes an adjusting mechanism 400, the adjusting mechanism 400 is mounted on the base 100, and the yarn bundling mechanism 200 is movably mounted with the base 100 through the adjusting mechanism 400.

The mounting frame 310 is a platform for supporting the induction detection sensor 320, and has a chute 311 formed thereon. A chute 311 extends along the body of the mount 310. The sensing detection sensor 320 is a sensing element for detecting whether the aramid yarn is continuous, and is placed in the chute 311, so that the state of the aramid yarn can be accurately sensed.
Preferably, the inductive detection sensor 320 in this embodiment is a proximity switch. The proximity switch is a sensor capable of sensing a position without mechanical direct contact with a moving part, and when an object approaches a sensing surface of the switch, the switch can be operated without mechanical contact and any pressure applied, so that a computer (plc) device provides a control instruction. When the yarn breakage occurs, the proximity switch does not sense, so that the yarn breakage alarm is triggered. The signal generated by the proximity switch is transmitted to a control system or an industrial control system, and if the yarn breakage or the discontinuity of the aramid yarn is detected, the system immediately triggers an alarm to inform an operator or take necessary control measures.
Further, the induction detecting mechanism 300 in the present embodiment is provided in plurality. The plurality of sensing mechanisms 300 are distributed at different locations along the path of the collected aramid yarns. Each sensing detection mechanism 300 is responsible for monitoring the state of the aramid yarn at the position of the sensing detection mechanism, and can sense the aramid yarn of a plurality of parts at the same time, so that comprehensive detection is ensured, and the detection efficiency is improved.
Preferably, in this embodiment, the second yarn hole 110 and the first yarn hole 210 are porcelain eyes. The porcelain eye is a small hole with a smooth surface made of ceramic material. In the aramid yarn breakage detecting device, the second yarn-tying hole 110 and the first yarn-tying hole 210 are both in the form of porcelain eyes. Because the surface of the porcelain hole is smooth, the aramid yarn cannot be subjected to excessive friction when passing through the holes, so that the aramid yarn is prevented from directly rubbing against the hole wall, and the risk of tearing or breaking the aramid yarn is reduced. By using porcelain eyes, it is ensured that the aramid yarn maintains its integrity while passing through the second and first tuft holes 110, 210 without being unnecessarily damaged.
