Problems solved by technology
However, there are certain defects. The electrode contact type is exposed to the outside and is affected by flying flowers. The electrode contact is often poor and will cause broken ends and no action.
Infrared direct-firing type, also due to the existence of flying flowers on the direct-firing tube, will often cause misoperation
The spring electrode is closed contact type. Although flying flowers generally do not enter, warp winding generally has about 800 yarns wound at the same time, and such about 800 electrodes are in contact with the spring. Due to long-term use, the spring will be damaged. The change of the elastic coefficient, and the change of the elastic coefficient will cause the change of the elasticity. It is because of this change that the tension will change, and sometimes it will cause malfunction
So up to now there is not a particularly good method to carry out good and effective detection of warp yarn breakage

specific Embodiment approach 2
[0028] Just as the method described in Embodiment 1, only the moving object is the warp yarn on the warping machine. During the warp yarn winding process, according to the device of the present invention, when the warp yarn is being wound, a certain amount of friction sound will be generated on the surface of the friction body, and it is judged that the equipment is operating normally. Once a broken yarn occurs, the warp yarn will The detection device of the installed electronic circuit has no signal output, and the electronic circuit has no signal reception at once, and it is judged that there is a fault, and the executing agency stops immediately.
specific Embodiment approach 3
[0029] Just as the method described in the specific embodiment one and two, only the moving objects are changed into other lines, other bars, such as plastic lines, plastic wire ropes, copper wires, copper wire ropes.
specific Embodiment approach 4
[0030] Just as the described method of specific embodiment, just moving object is changed into fiber thread, as other fiber bar, fiber thread, fiber yarn such as glass fiber, ramie fiber, rayon.

The invention discloses a break detecting method. The break detecting method is an effective detecting means which takes friction sound generated by movement of an object and a friction body on the surface of the friction body as a sound source, uses a sound pick-up to pick up the friction sound, and judges the operation of a circuit by electronic amplification in a sound picking-up manner that whether the friction sound picked up by the sound pick-up exists or not is converted into whether a corresponding electric signal is changed or not. In fact, the brake detecting method is a new thought of technical application for converting the change of the friction sound signal into corresponding change of the electric signal.
Description
technical field [0001] The end detection method of the present invention relates to the field of textile technology, in particular to the technical field of finishing or winding yarn stripes or yarns in the process from the weaving process to the pre-weaving process, in particular to cotton slivers and yarns The technical field of the automatic detection method of broken ends. Background technique [0002] As far as the current warp is concerned, before spinning and weaving, according to the requirements of the fabric, hundreds of warp yarns are wound on a warp shaft in the preparation process according to the requirements of the fabric, that is, the so-called warping process. The thread often breaks, and once the thread is broken, the winding machine should be stopped immediately, and the machine can only be started for winding after the broken end is connected. If the machine cannot stop immediately after the thread is broken, and the broken end is rolled onto the warp be...
