Description
Technical field
The present invention relates to knot detection technique field, particularly to a kind of knot detection device and detection method thereof.
Background technology
During glass fibre folded yarn doff, raw tow need to be extracted from multiple precursor cake high speed (being typically in more than 300m/min) respectively and be merged into one big strand of glass fiber yarn, on winder, then be wound into cylindric yarn group.Precursor cake is to be obtained than back and forth arranging and wind up on wire-drawing machine head layer by layer according to certain winding displacement by glass fiber precursor bundle in drawing process, and its profile is similar to horse-saddle, for doff after drying.
Precursor cake contacts with each other between ectonexine raw tow, and there is certain cohesive force each other owing to fiberglass surfacing is coated with wetting agent, and the size of this cohesive force is often inconsistent, time big time little.Overcome this cohesive force by the traction of winder during doff, raw tow is extracted from precursor cake.The product of corresponding different model, the quantity of the raw tow that a precursor cake is extracted out, being only of having is a branch of, and what also have is many beam splitting precursor, and many beam splitting precursor can be that ten bundles are even more, and the multi beam raw tow extracted out from a precursor cake is called many beam splitting precursor.
In the process that raw tow extracts from precursor cake, due on precursor cake during cohesive force between ectonexine raw tow big time little, inappropriate situation often occurs, at this moment the second layer even third layer or more multi-layered raw tow are taken out of by internal layer raw tow, ravellings group or knocking over knotting will be gone out, herein collectively referred to as knot.For some products (such as hard many beam splitting precursor product), that less knot allows for but it should stop bigger knot to enter yarn group, and for other products (such as soft single beam splitting precursor product), even if slight knot is also definitely unallowed.
In prior art, the device for detecting knot can not cannot distinguish between the size of knot, and same interception simultaneously notice winder are shut down, and including the less knot allowing appearance on some products, this will result in the seriously low of production efficiency.Even if because hard many beam splitting precursor product that quality is best, in the process that raw tow extracts from precursor cake, much little knot all occurring, but user will not be produced puzzlement more without influence on its product quality.If these little knots are all detected and shut down, by causing that much unnecessary winder is shut down and manually restarts, thus seriously reducing production efficiency.
Meanwhile, because the raw tow extracted from precursor cake, its thickness much all can more than 2mm, although the thickness of raw tow is not over 1mm, but width can more than 2mm, and especially many beam splitting precursor especially can more than 2mm.Additionally, winder drags in the process that precursor is extracted out at a high speed from from coil to coil precursor cake and wound, the high-speed motion of raw tow is not stable, but advances along near linear and with unstable vibration, Oscillation Amplitude is approximately in ± 5mm within the scope of.And for detecting the device of knot in prior art, its sensing chip notch is sized to 0.8 millimeter 2 millimeters, cause raw tow will inevitably with sensing chip generation strong friction, thus damaging the wetting agent film even injury of primary tow of fiberglass surfacing, produce wool yarn.
Simultaneously; prior art is used for the device detecting knot when running into the knot more than 2mm; knot can be forced to stop by sensing chip immediately; make winder shut down simultaneously; though and winder power-off shut down but due to rotator inertia may proceed to rotate a small distance; thus producing great tension force on raw tow, causing that sensing chip is pulled off to this section of raw tow of winder (being even wound up into the part raw tow in yarn group) internal a large amount of individual glass fibers silks, raw tow intensity declines to a great extent.And if the raw tow that these intensity decline to a great extent can not be removed in middle product completely, open defect will be produced on product.
Simultaneously, owing to precursor cake existing between ectonexine yarn bundle the often inconsistent cohesive force of size, in addition effect of inertia when raw tow is extracted out at a high speed, when therefore precursor being extracted from precursor cake, raw tow some can stretch tight tightlier, and some can be very lax, thus the instantaneous velocity that raw tow advances also is inconsistent, there is this species diversity especially between multiple precursor cakes.During doff, owing to the raw tow extracted from multiple precursor cakes exists above-mentioned speed difference, and after being merged into one big strand of glass fiber yarn, raw tow is each other owing to mutual friction etc. can produce the effect of carrying secretly.Therefore, the glass fiber yarn of the segment length obtained after being combined, the length of raw tow therein is inconsistent.And inconsistent in this length, reflect in the composite product adopting glass fiber reinforcement, it is exactly that part raw tow is stretched tight very straight, bear maximum tension at first, and part raw tow is very lax, just bear maximum tension after arriving the part raw tow drop stretching tight directly, imply that in composite, not all fiber bears maximum tension simultaneously, thus the mechanical property of composite can not reach the best.
In sum, there is following defect in knot of the prior art detection:
(1) size of the knot allowed can not be controlled according to actual needs；
(2) damage of glass fiber precursor bundle is big；
(3) individual glass fibers silk is broken；
(4) the raw tow length in glass fiber yarn after merging is inconsistent.
