Description

Stranded broken yarn detection device

Technical Field

The utility model relates to the field of mechanical devices, concretely relates to stranding broken silk detection device.

Background

Normally, the strand 3 is wrapped around the inner liner 16 by twisting the steel wires into a strand in a regular spiral arrangement around the centerline of the inner liner 16 on a stranding machine.

The strand 3 is inevitably broken during processing.

In the prior art, a broken yarn of the strand 3 is detected by using the inner tube 16 and an iron ring wrapping the strand 3 as two contacts of a contact switch, and moving the inner tube 16 wrapping the strand 3 through the iron ring. Since the steel wire is twisted into a strand and wound on the inner lining tube 16, the broken wire (broken steel wire) is generally scattered in an umbrella shape and contacts the iron ring once the steel wire is broken, and whether the strand 3 has broken wire can be judged by whether the iron ring is conducted with the strand 3; if the iron ring is communicated with the strand 3, the strand 3 has broken wires, otherwise, the broken wires do not exist.

The above method of detecting a broken yarn of strand 3 has the following drawbacks: the contact iron ring is not necessarily scattered in an umbrella shape after the steel wire is broken, and if the broken wire is not scattered in the umbrella shape, the broken wire of the strand 3 cannot be detected, so that the detection result is inaccurate.

When the device is used, laser emitted by a laser emitting port of the displacement sensor irradiates the strand 3, the distance between a reflecting surface of the strand 3 and the laser displacement sensor 4 is measured, and then the state of the strand 3 is detected and analyzed by matching with the PLC, the AD conversion module and the HMI human-machine interface. Because the strand 3 is a steel wire rope wound in a spiral mode, if the starting point of the broken wire is not on the detection surface of the laser displacement sensor 4, the strand 3 can be quickly transferred to the detection surface of the laser displacement sensor 4 in the moving process. The laser displacement sensor 4 determines that the wire is broken when the grooves appear for a certain number of times in the unit time on the detection surface of the laser displacement sensor 4, for example, the grooves appear for 5 times in 1S continuously.
