Abstract
A weft straightener which is adopted in a setting machine or a printing machine comprises the following components: a plurality of fabric guide rollers, an oblique weft correction straight roller, an arc weft correction bent roller, a light source and a detector which are provided behind the oblique weft correction straight roller and the arc weft correction bent roller. The utility model is characterized in that a plurality of sets of light sources and corresponding detectors are provided in front of the oblique weft correction straight roller and the arc weft correction bent roller. The weft straightener is advantageous in that: after the light source and the detector which are provided at a fabric inlet end detects the oblique weft or the arc weft, an oblique weft correction mechanism can perform real-time instant correction; and light sources and detectors which are provided at the rear part perform signal feedback for the corrected oblique weft thereby greatly improving the oblique weft correction effect and qualified rate of the fabric.
Description
Technical field
The utility model relates to a kind of weft straightener that weaving is adopted on setting machine or the printing machine in producing.
Background technology
During weaving was produced, the skew of weft phenomenon can appear in fabric, comprises oblique weft or arc latitude, is the float of fabric.Oblique weft is that weft yarn is oblique in the fabric, with the warp thread out of plumb, by weave or back arrangement processing in fabric tension force inconsistent due to, oblique horizontal stripe appears when serious, destroy fabric fleuron, on clothes, cause distortion, influence outward appearance.The arc latitude is that weft yarn is convexly curved in fabric, by weave or when arrangement back natural selvedge with fabric in the middle part of suffered tension force inhomogeneous due to, can cause fabric fleuron or fabric construction crooked.
In order to correct this skew of weft phenomenon, comprise oblique weft and arc latitude, on setting machine or printing machine, weft straightener is set usually.Weft straightener comprises light source, detection system and well straightening executing agency three parts.
Light source adopts solid infrared device or visible light source, adopts dull and stereotyped flat fire, makes light even.
Detection system is divided into transmission-type and reflective two kinds again.The light source casing of transmission-type detection system and detector are installed in the both sides of running textile respectively, the light that sends by light source with the structure imaging of fabric weft yarn on the high-accuracy optical pickocff on the detector head, by the comparison of signal that a plurality of photoelectric sensors are produced, can obtain the angle character value of weft yarn.Light source can be regulated light-source brightness automatically along with the variation of fabric construction.The light source of reflective detection system and detector are installed in the same side of fabric.The light that light source sends by the comparison that a plurality of photoelectric sensors are produced signal, draws the characteristic value of weft yarn with on the high-accuracy optical pickocff on the weft yarn structure reflected back detector head of fabric.
Well straightening executing agency divides the straight roller of well straightening latitude again and entangles arc latitude roller.The straight roller of well straightening latitude is 1～3, is installed in the conditioning box, and by motor or hydraulic drive conditioning box, the data that conditioning box records according to detector are rotated corresponding angle and corrected oblique weft.Entangle arc latitude roller and also be 1～3, the data that obtain according to detector drive and swing corresponding angle correction arc latitude by motor or hydraulic mechanism.
The defective of existing weft straightener is that light source and corresponding detector are installed in the back of entangling skew of weft mechanism, be the straight roller of well straightening latitude and entangle the back of arc latitude roller, just correcting skew of weft earlier detects again, this device just has role of correcting to the fabric of long segment skew of weft, can not detect correction in real time to short-movie section skew of weft.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of weft straightener that can overcome the real-time detection control of above-mentioned defective.
The utility model solves the problems of the technologies described above the technical scheme of being taked: a kind of weft straightener, comprise some fabric guide rolls, the straight roller of well straightening latitude, entangle arc latitude roller, and be installed in the straight roller of described well straightening latitude and entangle the light source and the detector of arc latitude roller back, be characterized in, at cloth intlet, promptly at the straight roller of well straightening latitude with entangle arc latitude roller front and also be provided with multiple sets of light sources and corresponding detector.
The beneficial effects of the utility model are:
Be installed in the multiple sets of light sources of cloth intlet and detector after detecting oblique weft or arc latitude, entangle skew of weft mechanism and can carry out real-time correction immediately detected skew of weft, and the multiple sets of light sources of back and detector only carry out signal feedback after correcting skew of weft, so not only the long segment skew of weft is played role of correcting, seam crossing or short-movie section skew of weft that can also fabric play real-time role of correcting, have improved the qualification rate of entangling skew of weft effect and fabric thus greatly.

Label declaration in the accompanying drawing
The fabric that 1-enters, the straight roller of 2-well straightening latitude, 3-entangles arc latitude roller,
The 4-fabric guide roll, the 5-light source, the 6-detector,
The fabric of 7-output, 8-rotating shaft, 9-conditioning box.
The specific embodiment
Light source that is installed in cloth intlet that the utility model is newly established and detector can adopt various forms of commercially available traditional products or design voluntarily.During installation, not enough as locus in the frame, can improve bracket height, and set up fabric guide roll, to guide fabric by getting final product between light source and the detector.The light that light source sends with the weft yarn structure imaging on the high-accuracy optical pickocff on the detector head, comparison by signal that a plurality of photoelectric sensors are produced, draw weft yarn angle character value, the data that record according to detector, well straightening executing agency is promoted by motor or hydraulic mechanism, rotate respective angles and correct oblique weft, motor or hydraulic mechanism drive and make and entangle arc latitude roller swing respective angles and correct the arc latitude.
Claims (1)
1. weft straightener, comprise some fabric guide rolls, the straight roller of well straightening latitude, entangle arc latitude roller, and be installed in the straight roller of described well straightening latitude and entangle the light source and the detector of arc latitude roller back, it is characterized in that: at cloth intlet, promptly at the straight roller of well straightening latitude with entangle arc latitude roller front and also be provided with multiple sets of light sources and corresponding detector.
