Description
Technical field
The present invention relates to a kind of multifilament for twisting machine and twist with the fingers ingot, this multifilament is twisted with the fingers ingot and is had upper spinning chamber and lower spinning chamber, described upper spinning chamber and lower spinning chamber coaxial rotation in opposite direction, wherein drive a spinning chamber and transfer the motion to another spinning chamber by planetary gear.
Background technology
Twisting is the weaving operation for improving yarn quality. Because single thread line cannot meet the requirement of deep processing or end product in stability and uniformity, so winding twisted each other by two or more yarn.
In this, feed twisting machine about by yarn, have feeding mode two kinds different. Main yarn is wrapped in feed package or is wound up into by main yarn in all cases on aligned with each other two bobbin. Strand is, is understood to a collective noun in this respect, for all linear textiles structures that yarn of the same race or not of the same race is twisted. Term " line " comprises all linear structures scope of the present application planted agent, for instance yarn, film strip, tubulose, webbing etc. In order to simplify term, term " line " is used for the replacement being likely to occur in scope of the present application with identical implication.
In four times of twisting technique situations, machinery spindle often rotates once, and yarn is twisted four times. Under magnet effect, the wharve with untwisted precursor is maintained at the fixed position rotated on twisting spindle. Yarn is drawn from feed package, directed around the outside of feed package, subsequently into one of them of two spinning chambers. Yarn is delivered to the second spinning chamber by the first spinning chamber, and when yarn occurs again from the second spinning chamber, by again around the guided outside of feed package and be finally wound.
When two spinning chambers rotate in opposite direction, yarn rotates around wharve, and before yarn enters the first spinning chamber, produces air ring in first, and after yarn leaves the second spinning chamber, produces the second outer air ring operated in opposite direction.
Due to around feed package directed twice in opposite direction of the yarn of twisting, therefore spindle is gone around, and yarn is twisted four times.
EP0863234A1 discloses a kind of four times of twisting machines, and on this twisting machine, first yarn upwards involves via supply bobbin, and guides downwards along inside strands passage and enter upper spinning chamber through yarn guiding port. Yarn is sent to lower spinning chamber through yarn road from upper spinning chamber. Then, yarn is directed upwards to coil winding machine from lower spinning chamber along yarn path. In order to realize the contrary direction of rotation of spinning chamber, upper spinning chamber and lower spinning chamber all drive individually through belt transmission.
According to EP0863234A1, the shortcoming of these four times of twisting machines is that machine is driven by two drive divisions, and this drive division comprises relevant belt and belt pulley.This makes the structure driving structure complex, and makes it take larger space.
Four two-for-one twisting spindles for twisting machine described in EP1726693A2 have employed the driver element of improvement. Not being use two driver elements (one spinning chamber of each drive unit drives), but use the planetary gear of improvement, result remains a need for a driver. For this purpose, by planetary design being so that its inner member and lower spinning chamber define full unit, similarly planetary external member and upper spinning chamber define full unit. Additionally, internals is by being fixed to axle by press-fit, this axle is driven by motor. And internals forms sun gear, and external member is hollow wheel, is designed as pinion frame keeper or retainer according to EP1726693A2 pinion frame, to hold the planetary component of spherical or analogous shape.
If driving this axle and therefore driving internals, then descend spinning chamber to rotate, and therefore similarly make the line outlet in the second guide road rotate. Owing to retainer is fixed by magnet, ball can not rotate around internals, but ball rotation therefore motion of driven shaft is transferred to outer member, and therefore it is also transmitted to spinning chamber, after being formed interior air ring by guide road, yarn is transferred in spinning chamber.
According to EP1726693A2, this four two-for-one twisting spindle have drawbacks in that due to gear ratio, lower spinning chamber rotating speed is higher than upper spinning chamber, therefore turns faster. Spinning chamber this species diversity on rotating speed weakens actual twisting effect, because air ring has different yarn tensions, to this, outside and faster air ring have higher yarn tension. Owing to outside air ring is the limiting factor for four two-for-one twisting spindles, this is particularly disadvantageous. By the bad distribution of different yarns tension force, less desirable broken string occurring, this is extent of damage reliability finally reduce the efficacy levels of twisting machine generally.
The inside air ring smaller due to bigger outside air ring rotates faster, so the method described in EP1726693A2 also has relatively high energy requirement.
Summary of the invention
Twisting with the fingers ingot as starting point using above-mentioned such, the main task of the present invention is to propose to twist with the fingers ingot for the multifilament of twisting machine, and ingot twisted with the fingers by this multifilament makes outside air ring turn slowly than internal air ring, and energy consumption also reduces accordingly simultaneously.
According to the present invention, this task is completed by the feature of first aspect.
Foundation other embodiments of the invention and advantage are described in other side.
In order to solve this problem, provide according to first aspect: planetary outer ring is connected to lower spinning chamber, and this planetary inner ring is connected to spinning chamber.
Owing to lower spinning chamber is driven, this moves through planetary gear and is transferred to spinning chamber, and outer air ring turns round and round with the rotating speed lower than interior air ring. This causes that outer air ring is exposed to the yarn tension lower than interior air ring. This advantageously reduces the quantity of broken string. Add the reliability of program, and therefore ultimately increase the efficacy levels of twisting machine.
Additionally, it have been experienced that: if the rotating speed of the outer air ring of the spinning chamber operated in opposite direction is lower than interior air ring, twisting process is advantageous for by this.
Respectively outer ring or inner ring and lower spinning chamber or between spinning chamber be suitable for and permanent connection realizes preferably by crimping mode. But, within the scope of the present invention, other interconnection technique is equally applicable to this connection.
According to second aspect, planetary actuated element is advantageously mounted to the bearing clearance with subnormal bearing clearance CN.
Preferred embodiment includes outer ring, inner ring and the rolling element worked when without usual bearing clearance. This shows: when being installed by the gap of two rotating shafts, and planetary actuated element depends on the state of under lap structure.
In this, bearing clearance can be regarded as a bearer ring can relative to another bearer ring from a boundary position to the measured value of another boundary position displacement. The measured value of necessary bearing clearance is especially determined by gap, heat-economy and load.
Normal bearing clearance C N is determined so that, retains general gap, normal operating state and operates bearing clearance fully. According to the present invention, not having any bearing clearance owing to planetary actuated element is arranged to, or only have a small amount of gap, institute is so that bearing obtains relatively without backlash.
According to the third aspect, retainer can be used as planet carrier, and it is held against rotating by magnet.
In order to ensure rolling element rotation, and transferring the motion to the spinning chamber being driven downwards from driven spinning chamber, retainer needs to be held against rotating with it. This carries out preferably by magnet, and what adopt here is contactless structure.
According to fourth aspect, toroidal magnet keeper can be set in the preferred case, the internal diameter of this keeper be designed so that for lead into yarn and form locking groove.
If the edge expansion of the inner radius of magnet holder, such as, being bent upwards from edge, then twist with the fingers the lower area formation capture slot of ingot at multifilament, it is reliably prevented such as yarn or the end of a thread after disconnecting and is pulled into and is gathered in multifilament sth. made by twisting ingot or arrive planetary gear.

Yarn 3 unwinds from package 2, and the flier 6 being conducted through rotation arrives braking district 7. After cabin formula Yarn Brake 8 is braked in advance, yarn 3 leaves flier 6 via top round end 9, as internal air ring 4, is directed to upper spinning chamber 10 around vertical wharve S.
Here yarn 3 enters the Shang Sha road 11 of upper spinning chamber 10, and the center twisting with the fingers ingot 1 at multifilament is directed to spinning chamber 14 via deflector. Yarn 3 and then be deflected via lower spinning chamber 14 Zhong Xiasha road 15, is then directed upwards, as outside air ring 5, around wharve S, simultaneously around internal air ring 4.
Twisting with the fingers above ingot 1 at multifilament, along with the rotation of yarn, yarn 3 is directed to rewind 19 from air ring yarn introduction member 18 now.
In traverse during spinning chamber 10 and lower spinning chamber 14, owing to the impact of the planetary gear 20 according to the present invention, upper spinning chamber 10 and lower spinning chamber 14 rotate in opposite direction, so yarn turns round and round.
Altogether around package 2 directed twice in opposite direction of the yarn 3 twisted, thus yarn rotates twisting four times with ingot every time.
As it is shown in figure 1, spinning chamber is driven by tangential belt T, this tangential belt T drives the lower spinning chamber axle 16 being saved in housing G by wharve W.
Figure it is seen that on the top of lower spinning chamber axle 6, the outer ring 21 of planetary gear 20 is connected to lower spinning chamber axle 16 by crimping mode.The inner ring 22 of planetary gear 20 forms integral part again by crimping mode and upper spinning chamber axle 13. Upper spinning chamber 10 and lower spinning chamber 14 connect from there through planetary gear 20, and operate in opposite direction at any driving condition, according to being defined as " i is less than 1 " corresponding to planetary gear ratio of present invention design, i here draws by inputting the ratio of speed and output speed.
Thus, it is achieved that from upper spinning chamber 10 to the rotation in opposite direction of lower spinning chamber 14, it is necessary to there is resistance torque M, for planetary gear 20. This is generated in radial directions by retainer 23. Retainer 23 radially outwardly direction is connected with toroidal magnet retainer 24, and external stability magnet 26 is produced resistance torque M via magnet 25 by this toroidal magnet retainer. In order to avoid eddy current effect, the part rotated between magnet 25 and fixing magnet 26 of lower spinning chamber 14 is made up of antimagnetic material in this region.
