Abstract
This invention discloses an elliptical gear sword pole loom flexible latitude inducing method and latitude inducing structure. This invention uses elliptical gear structure and crank rocker structure, it changes the uniform running of the loom spindle to the non-uniform swaying of the driving roller gear, and then it goes through the wheels' journey expanding and changing to realize the moving rule of the sword tine. The structure can realize eceiving power and inducing latitud
Description
Technical field
The present invention relates to the loom weft insertion device, be specifically related to flexible Weft insertion method of a kind of elliptic gear rapier loom and weft insertion device.
Background technology
The effect of weft insertion device is that the non-at the uniform velocity regular linear reciprocation that the uniform speed rotation with loom main shaft is converted into the sword head moves.At present, the Weft insertion mechanism of rapier loom of selling on the market mainly contains at home: the conjugate cam weft insertion device, and the type mechanism is easy to satisfy the characteristics of motion of wefting insertion requirement, but the cam profile requirement on machining accuracy is quite high, as exist error just to produce impact; Variable-pitch auger transmission weft insertion device, the secondary processing difficulties of the variable-pitch auger of the type mechanism; Plane six connecting rods send latitude, four link rob latitude mechanisms, can conveniently realize " relay " wefting insertion, but its motion of weft-insertion rule design flexibility is not as the conjugate cam weft insertion device; The space four-links weft insertion device, its motion of weft-insertion rule design flexibility send latitude, four link rob latitude mechanisms not as plane six connecting rods.
Summary of the invention
The purpose of this invention is to provide flexible Weft insertion method of a kind of elliptic gear rapier loom and weft insertion device, this mechanism can satisfy the weaving process requirement, realizes the non-at the uniform velocity straight reciprocating motion rule and the requirement of " relay " wefting insertion of sword head; Process and assemble is convenient simultaneously, guarantees precision easily.
In order to achieve the above object, the technical solution used in the present invention is:
One. the flexible Weft insertion method of elliptic gear rapier loom: adopt elliptic gear mechanism and crank and rocker mechanism, the uniform rotation of loom main shaft is transformed into the initiatively non-at the uniform velocity swing of roller gear, thereby amplifies through the stroke of train again and commutation realizes the characteristics of motion of sword head.
Two. the flexible weft insertion device of elliptic gear rapier loom:
Initiatively elliptic gear is housed on the loom main shaft, initiatively elliptic gear and driven elliptic gear are meshed, initiatively the pivot of elliptic gear is the focus of active elliptic gear, the pivot of driven elliptic gear is the focus of driven elliptic gear, one end of crank and the focus of driven elliptic gear are fixed, one end of connecting rod and the other end of crank are hinged, one section arc groove at roller gear center is not hinged the other end of connecting rod with not being positioned at initiatively, the moving point of rocking bar is exactly that connecting rod and arc groove are hinged a little, the center of circle of arc groove is the end points of connecting rod, initiatively roller gear is meshed with driven cylindrical gear, initiatively bevel gear is housed on the axle of driven cylindrical gear, initiatively bevel gear is meshed with driven bevel gear on another, and the sword wheel is housed on the driven bevel gear axle, and sword is equipped with sword belt on taking turns.
Initiatively the initial installation phase angle [alpha] of elliptic gear and driven elliptic gear is 20 °～50 °.
Crank is that β is 30 °～60 ° with the line phase angle of active elliptic gear and driven elliptic gear focus.
The beneficial effect that the present invention has is: this mechanism can satisfy the weaving process requirement of Rapier looms, finishes and send latitude and connect the latitude action, and can realize " relay wefting insertion " by send latitude and the parameter that meets latitude mechanism about changing, and reduces weft tension; This mechanism's process and assemble is convenient simultaneously, guarantees precision easily.

The specific embodiment
Below in conjunction with accompanying drawing, example of the present invention is described further.
As shown in drawings, when the present invention works, the loom main shaft uniform rotation, initiatively elliptic gear 1 is contained on the loom main shaft, is meshed by active elliptic gear 1 and driven elliptic gear 2, the loom main shaft uniform rotation is converted into the non-uniform rotation of driven elliptic gear.Initiatively the pivot of elliptic gear 1 is the focus of active elliptic gear, and the pivot of driven elliptic gear 2 is the focus of driven elliptic gear.By the crank rocker transmission, the non-uniform rotation of driven elliptic gear 2 is converted into the non-at the uniform velocity swing of rocking bar CD again.The end A of crank AB and the focus of driven elliptic gear 2 are fixed, and the end of connecting rod BC and the other end of crank AB are hinged, the other end of connecting rod BC be not positioned at initiatively roller gear Z
1One section arc groove at center is hinged, the moving point of rocking bar CD is exactly that connecting rod BC and arc groove are hinged a little, the center of circle of arc groove is the terminal B of connecting rod, radius is the length of connecting rod BC, the C point is fixed can adjust the position in arc groove after, can realize being contained in the adjustment of the sword head traverse on the sword belt 4 like this, the characteristics of motion when not changing simultaneously the handing-over weft yarn again.Pass through the active roller gear Z of train at last
1, driven cylindrical gear Z
2, bevel gear Z initiatively
3With driven bevel gear Z
4Stroke amplify and direction changes, rocking bar non-at the uniform velocity swung the non-straight reciprocating motion at the uniform velocity clocklike that is converted into the sword head.Active roller gear Z
1With driven cylindrical gear Z
2Be meshed driven cylindrical gear Z
2Axle on initiatively bevel gear Z is housed
3, active bevel gear Z
3With the driven bevel gear Z on another
4Be meshed driven bevel gear Z
4Sword wheel 3 is housed on the axle, on the sword wheel 3 sword belt 4 is housed.One cover weft insertion device respectively is housed about loom, drive path is the same with operation principle, but the initial installation phase angle [alpha] of elliptic gear is different with the line phase angle β of driven elliptic gear 2 focuses with active elliptic gear 1 with crank, thereby realizes " relay " wefting insertion.
