Description
Technical field
The invention belongs to technical field of textile machine, are related to the improvement of automatic winder, specifically a kind of automatic winding
The residual yarn detection device of machine and detection method.
Background technique
Automatic winder is by the lesser incidental looping of capacity into the biggish cylinder yarn of capacity, and a cylinder yarn is usually by 30-40
A incidental looping forms, and during coil unwinding, most of coil can be unwound completely completely at blank pipe, and blank pipe returns to upper track
Process is reused, but always has part coil to fail to unwind completely completely, seldom a part of yarn is left on spool, even only
There are several loop yarns, the coil of this only a small amount of yarn is referred to as residual yarn.In the higher pellet type automatic winder of the degree of automation
On, blank pipe and residual spool are extracted automatically by dedicated pipe drawing device, are reused to return to previous process, it is necessary to by residual yarn
Pipe is separated from blank pipe.On existing automatic winder, usually there are two types of modes for residual yarn detection device, and one is utilizations
Imaging sensor judgement, accuracy is high, but cost is very high；Second is detected using hairbrush, and detection device is at low cost, but hair
Brush is prone to wear, and accuracy in detection is low, and needs often adjustment detection device, affects the working efficiency of automatic winder.
Summary of the invention
The present invention to solve the above problems existing in the prior art, provides a kind of residual yarn detection device of automatic winder and inspection
Survey method, at low cost, not easy to wear, accuracy in detection is high, after once mounting debugging can long-term safety reliably run.
