The excess weft insertion system of Rapier looms of the present invention is at work: see Fig. 1, Fig. 6, Fig. 7, the weft yarn 4 being selected as special Wei Tiao district is not from being directly penetrate to select latitude to refer to 0-6 and be through to lead to after five cord roller 3-2 and four pulley 2-3-2 form class " M " types guiding again and select latitude to refer to 0-6 after weft detector 0-5 draws, weft yarn 4 is formed after class " M " type guiding through five cord roller 3-2 and four pulley 2-3-2 and is in fact equivalent to lay in a part of weft yarn, and storage level can regulate as required.The position of cord roller 3-2 is relatively-stationary, and the position of pulley 2-3-2 swings up and down under the effect of swing mechanism 1, and wefting insertion cycle and hunting period synchronously, namely can realize in each wefting insertion cycle once to storage and the dispose procedure of weft yarn 4.See Fig. 6, Fig. 7 elaborates to this process: the rotation of camshaft 1-3 drives the cam 1-2 be installed on it to rotate, and fork 1-6 is offseted by rotor 1-6-1 and cam 1-2 all the time under the effect of back-moving spring conjunction 1-5, so the rotation with cam 1-2 swings up and down by fork 1-6, the upper bottom of fork 1-6 drives the pulley block mechanism 2 being installed on its one end to move up and down further.Weft yarn 4 forms class " M " type guiding through five cord roller 3-2 and four pulley 2-3-2, when pulley block mechanism 2 moves from bottom to top, " M " uprises gradually, namely realizes storage weft yarn, and " M " will become short gradually when pulley block mechanism 2 moves from top to bottom, then realize release weft yarn.
Camshaft 1-3 uses former loom Scissors box power transmission shaft and both solved power resources, decreases powerdriven design, achieves again pulley block mechanism 2 and swings up and down cycle and the equal and synchronous requirement of wefting insertion cycle.Except meet equal on the cycle and synchronous not enough, must consider that the characteristics of motion that pulley block mechanism 2 swings up and down can coordinate former weft insertion system work very well and can realize the effect that we will reach simultaneously, and pulley block mechanism 2 swing up and down the outline line that the characteristics of motion finally depends on cam 1-2.The outline line of cam 1-2 is divided into yarn supply A as shown in Figure 6, quiescent centre B, release district C, cam 1-2 rotates counterclockwise with camshaft 1-3, with fork 1-6 upper rotor part 1-6-1 and cam 1-2 subtracting point for reference point, reference point rotates counterclockwise one week situation with cam 1-2 from the point of interface D point in A district and C district: 1.: in A district, fork 1-6 drives pulley block mechanism 2 to move from lowest point to peak by under the acting in conjunction of cam 1-2 and fork back-moving spring conjunction 1-5, peak in A district and separation place of B district, because the weft yarn 4 forming class " M " type guiding in this course through several cord rollers 3-2 and pulley 2-3-2 uprises gradually along with " M's " and is stored into excess and send in Weft handling device, so the A district claiming the outline line of cam 1-2 is yarn supply A, 2.: in B district, outline line due to B district cam 1-2 is the circle with cam 1-2 concentric, fork 1-6 will remain static, therefore be in maximum yarn storage amount state, so the B district claiming the outline line of cam 1-2 is quiescent centre B through the weft yarn 4 of several cord rollers 3-2 and pulley 2-3-2 formation class " M " type guiding in this course always, 3.: in C district, fork 1-6 drives pulley block mechanism 2 to move from peak position to peak by under the acting in conjunction of cam 1-2 and fork back-moving spring conjunction 1-5, touch the bottom in C district and separation D place of A district, because the weft yarn 4 forming class " M " types guiding in this course through five cord roller 3-2 and four pulley 2-3-2 along with the change gradually of " M " short, being stored into excess send weft yarn in Weft handling device to be released into rapidly in whole wefting insertion district under self larger resilient force, so claim the C district of the outline line of cam 1-2 for release district C.The yarn supply A of the outline line of cam 1-2, quiescent centre B, release district C, the Chu Wei district A and release district C that compares takies less angle, axle center, and quiescent centre B takies larger angle, axle center, make excess send Weft handling device to have fast storage like this, discharge fast, the feature of longer quiescent time, the weft yarn that release is conducive to discharging fast reduces the impact of warp thread thus reaches retraction evenly in the fell in wefting insertion district; Rapid storage can complete storing weft threads before sending latitude sword 0-8 to be with yarn wefting insertion, avoids yarn storage process on the impact of sword head wefting insertion.Require connect latitude sword 0-9 clipped weft yarn 4 exit fell front cam 1-2 enter release district C, the needs of different material and design style, the time that cam 1-2 enters the best point of release of release district C is also different, release too early, the weft yarn discharged is equal to directly draws from weft accumulator, discharged late, shed closed degree is comparatively large, affects the weft yarn discharged and evenly bounces back in wefting insertion shed open full width.The adjustment of the time of point of release is realized by the adjustment circumferential fixed position of cam 1-2 on camshaft 1-3.
Excess send understanding and the adjustment of the excess size of latitude, when cam 1-2 is in quiescent centre, the position of pulley 2-3-2 is in peak (upper), and weft yarn 4 forms class " M " type through some cord roller 3-2 and pulley 2-3-2 and is directed to the highest, and excess send the weft length in Weft handling device to be designated as L
greatly, when cam 1-2 goes to the separation D place of release district C and yarn supply A, weft yarn 4 forms class " M " type through several cord rollers 3-2 and pulley 2-3-2 and is directed to the shortest, and excess send the weft length in Weft handling device to be designated as L
little, excess=L that excess send Weft handling device to provide

greatly≈ 2nh, the height h changing " M " type guiding also just changes yarn storage amount L
greatlysize.
In order to avoid Chao Song latitude mechanism is on the impact of other weft yarn wefting insertion, in other weft yarn wefting insertion process, swing arm 1-6 enters inactive state of stopping.See accompanying drawing 8, the short stay cord of latitude that selects of latitude system (locally) 5 that selects being caused loom by the connection cord conjunction 1-6-6 being fixed on swing arm 1-6 one end regulates hook 5-3-1, latitude system (locally) 5 is selected to comprise multi-arm tap 5-1, long stay cord 5-2, select latitude Triangular Arm 5-3, long stay cord 5-2 one end is connected with multi-arm tap 5-1, another upper end with select latitude Triangular Arm 5-3 and be connected, multi-arm tap 5-1 can realize selecting latitude Triangular Arm 5-3 to realize pendulum counterclockwise extremely upper as required, maintain upper, be reset to bottom, maintain the next control, so be connected with selecting the short stay cord of latitude to regulate to hook 5-3-1 by the connection cord conjunction 1-6-6 other end that is fixed on swing arm 1-6 one end, can realize controlling fork 1-6 in units of each wefting insertion cycle to be separated with cam 1-2 and stop (corresponding select latitude Triangular Arm 5-3 place upper), corresponding when selecting bottom, latitude Triangular Arm 5-3 place, connection cord conjunction 1-6-6 place relaxed state, fork 1-6 recovers rotate with cam 1-2 and swing.
The invention solves traditional simple increase filling density or change the method for fabric tissue or its associating and because it is by the restriction of the reasons such as loom function, shaping characteristic complicated in the details of longitude and latitude intertexture own with affect and the actual contradiction being difficult to realize, achieves designer's idea and there is the broadwise bar of the wide and regularity of distribution of certain bar and broadwise bar region weft yarn covers design and the production of the special latitude bar style fabric of warp thread completely.
