Description
Technical field
The present invention relates to knot detection technique field, particularly a kind of knot detecting device and method of inspection thereof.
Background technology
During glass fibre folded yarn doff, need raw tow extracted from a plurality of former spinning cake high speeds (generally more than 300m/min) respectively and be merged into one large strand of glass fiber yarn, then be wound into cylindric yarn group at winder.Former spinning cake is in drawing process the glass fiber precursor bundle to be obtained than back and forth arranging and wind up on wire-drawing machine head layer by layer according to certain winding displacement, and its profile is similar to horse-saddle, is used for doff after the drying.
Be in contact with one another between the ectonexine raw tow on the former spinning cake, and because fiberglass surfacing is coated with size and has each other certain cohesive force, and the size of this cohesive force often is inconsistent, the time little when large.Traction by winder during doff overcomes this cohesive force, and raw tow is extracted from former spinning cake.The quantity of the raw tow of extracting out on the product of corresponding different model, former spinning cake, have only for a branch of, what also have is many beam splitting precursor, many beam splitting precursor can be ten bundles even more, the multi beam raw tow of extracting out from a former spinning cake is called many beam splitting precursor.
In the process that raw tow extracts from former spinning cake, because little when large during the cohesive force on the former spinning cake between the ectonexine raw tow, inappropriate situation often appears, at this moment the internal layer raw tow is taken the second layer even the 3rd layer or more multi-layered raw tow out of, will go out ravellings group or knocking over knotting, this paper is commonly referred to as knot.For some products (such as many beam splitting of hard precursor product), less knot be allow but should stop larger knot and enter yarn group, and for other products (such as soft single beam splitting precursor product), even slight knot also is definitely unallowed.
In the prior art, can not be able to not distinguish the size of knot for detection of the device of knot, interception also notifies winder to shut down simultaneously without exception, comprises the less knot that permission occurs on some products, and this will cause the lowly serious of production efficiency.Even because best many beam splitting of the hard precursor product of quality in the process that raw tow extracts, a lot of little knots all can occur from former spinning cake, more can not affect its product design but can not produce puzzlement to the user.If the knot that these are little all detects and shuts down, will cause a lot of unnecessary winders shutdown and manually restart, thereby seriously reduce production efficiency.
Simultaneously, because the raw tow that extracts from former spinning cake, its thickness much all can surpass 2mm, although the thickness of raw tow can not surpass 1mm, width can surpass 2mm, especially many beam splitting precursor can surpass 2mm especially.In addition, winder drag that precursor from coil to coil from former spinning cake is extracted out at a high speed and the process of reeling, the high-speed motion of raw tow is not to be stable, but advances and with unsettled vibration along near linear, Oscillation Amplitude is greatly in ± 5mm scope.And in the prior art for detection of the device of knot, its sensing chip notch size is arranged to 0.8 millimeter-2 millimeters, cause the raw tow will be inevitably and sensing chip generation strong friction, thereby size film even the injury of primary tow of damage fiberglass surfacing produce wool yarn.
Simultaneously; in the prior art for detection of the device of knot when the knot that runs into greater than 2mm; sensing chip can be forced knot to stop immediately; winder is shut down; though and winder has cut off the power supply and has shut down but because rotator inertia can be rotated further a bit of distance; thereby produce great tension force at raw tow, cause sensing chip to be broken to the inner a large amount of individual glass fibers silks of this section of winder raw tow (even being wound up into the part raw tow that yarn is rolled into a ball), 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 the middle product fully, will produce open defect at product.
Simultaneously, owing to there being the frequent inconsistent cohesive force of size on the former spinning cake between the ectonexine yarn bundle, effect of inertia when raw tow is extracted out at a high speed in addition, when therefore precursor being extracted from former spinning cake, raw tow some can stretch tight tightlier, and some can be very lax, thereby the momentary velocity that raw tow advances also is inconsistent, has especially this species diversity between a plurality of former spinning cakes.During doff, because there is above-mentioned speed difference in the raw tow that extracts from a plurality of former spinning cakes, and after being merged into one large strand of glass fiber yarn, raw tow is each other because the mutual meetings such as friction produce the effect of carrying secretly.Therefore, the glass fiber yarn of a segment length that obtains after being combined, the length of raw tow wherein is inconsistent.And inconsistent on this length, be reflected in the composite product that adopts the glass fibre enhancing, be exactly that the part raw tow is stretched tight very directly, bear at first maximum tension, and the part raw tow is very lax, will arrive the part raw tow that stretches tight the directly rear maximum tension that just bears that breaks, meaning is that not all fiber bears maximum tension simultaneously in the composite material, thereby the mechanical property of composite material can not reach best.
In sum, knot of the prior art detects and has following defective:
(1) can not control according to actual needs the size of the knot of permission;
(2) damage to the glass fiber precursor bundle is large;
(3) break the individual glass fibers silk;
(4) the raw tow length in the glass fiber yarn after the merging is inconsistent.
