As shown in Figure 1, the yarning part of ring spinner is provided with a spindle 10, and spindle 10 has driving wharve 11, and rotating band 12 is around driving the guiding of wharve 11 tangent planes so that drive spindle rotation.Spindle 10 is fixed on the step rail 13, and this step rail 13 stretches (not detailed showing) and carries a plurality of spindles 10 on the whole length of ring spinner.One spool 14 places on the spindle 10, and the yarn 15 that has been spun on its spool is wound into cop 16.
For spun yarn 15, yarning part is provided with a rings 17, and rings 17 surrounds spool 14 or cop 16 with one heart and is used as the twisting generating apparatus.One steel traveler 18 is arranged on the rings 17 so that it can be around the circumferential slippage of rings.Rings 17 is fixed on the ring rail 19, and ring rail is provided with rings opening 20 within rings 17, and spool 14 and the cop 16 that forms thereon stretch by this opening 20.
Ring rail 19 may with respect to step rail 13 move up or down in case in a known way established yarn 15 be wound on cop 16 taper in yarn district 21.One housing 52 is provided with round spindle 10.Housing has a minimum diameter, and this diameter is chosen to can freely move and can not hinder in spinning process the circular motion of the ballooning of yarn 24 of formation between thread-carrier 23 and steel traveler 18 even as big as holding ring rail 19 up and down together with steel traveler 18 and rings 17 and they.In the axial direction, housing device 52 stretches upwards the taper that causes cop 16 so far, and always complete conductively-closed cover surrounds around the yarn district, even also be like this when the full packages yarn.Housing 52 stretches the bag shape lower end that surpasses cop 16 vertically downwards, and has suction inlet 26 on the side, and this suction inlet 26 all leaves with a certain distance from the top edge 33 and the lower edge 32 of housing 52.
According to Fig. 1 and 1a, suction inlet 26 ' be designed to flute profile, and in this embodiment its length approximate spool 14 length 45%.In general, suction inlet 26 ' exhaust effective length 1 should equal 20% of spool length at least.
According to Fig. 1 a, flute profile suction inlet 26 ' in the above all is connected with one also along the narrower line of rabbet joint of the axial stretching, extension of spindle 10 with following.
In the embodiment that each illustrates in succession, suction inlet 26 also can be made up of several openings that distribute along the axial interruption of spindle 10, shown in the example among Fig. 1 b.
Have thereon the annular space that forms between the spindle 10 of cop 16 and the housing 52 by suction inlet 26 ', air guiding face 48,49 and 50 and the space that limited by unshowned side air guiding face and be connected on unshowned suction channel on Fig. 1 by a tube connector 34.
The top view of Fig. 2 illustrates the possible cross section shape of housing 52.Forward part at housing 52 is provided with a lid 46, and this lid can be provided with so that the operator is easy near cop 16 or spindle 10 with outwarding winding.
In practice, the housing 52 upper support ring rails 19 that seal fully on circumference may be problematic.For this reason, according to Fig. 3 and 4, in housing 52, be provided with an axial groove 64, can penetrate by clamping device 62 of this groove in the inner space of housing 52 so that supporting ring rail 19, and this clamping device be connected on the ring rail carriage 36 that is located at housing 52 outsides.Having along the groove 64 of the axial stretching, extension of spindle 10 in housing 52 makes clamping device 62 can move to length on the spinning process desired position.According to Fig. 3, groove 64 is arranged on the direction relative with the aspirator 27 that comprises tube connector 34 and air guiding face 48,49,50.Yet it can be arranged on any position on the circumference, be located at especially as shown in Figure 4 aspirator 27 near.
Annular space 37 for closed shield cover 52 can be provided with a sealing gasket 60 on groove 64, be preferably the elastic sealing gasket of overlap joint.
For avoiding setting up a groove 64, advised the embodiment of Fig. 5, wherein, clamping device 62 is arranged to U-shaped.Be at least partially disposed on a pillar 62 in the annular space 37 of housing 52 " overhang bracket ring rail 19; and be located at second pillar 62 of housing 52 outsides ' the end be connected on the ring rail carriage 36, this carriage 36 can axially moving along spindle 10 up and down.Length pillar, especially interior pillar is chosen to make that part 62 that connect two pillars when ring rail is in its uppermost position in fig-ure still are positioned at the below of the lower limb 32 of housing 52.
According to Fig. 6, the housing 52 of two adjacent spindles 10 can be designed to be integral at least in part.The side of the housing relative with protecgulum 46 has along the groove of the axial stretching, extension of spindle, this groove by another air guiding face 58 separately, be formed for the groove 64 of clamping device 62 and suction inlet 26 '.Air guiding face 58 is arranged to make the air of discharge to be imported in the tube connector 34 that links to each other with unshowned center suction channel.The air guiding face of two adjacent spindles 10 is integral setting, so a tube connector 34 is used for two spindles 10.In clamping device groove 64, be provided with a sealing gasket 60 again in case being communicated with between stop ring shape space 37 and the spinning room.The clamping device 62 that is supporting ring rail 19 is fixed on the ring rail carriage 36 by means of retaining element 54 and screw 56.
In the embodiment according to Fig. 6, rear end of housing 52 forms a side air guiding face relative with additive air guiding face 58, and this side guiding face has been determined the flow direction of the air that is sucked away.
At the spinning machine duration of work, spindle 10 and spool 14 and the cop 16 that forms on spool are with up to 25000 rev/mins or higher high-speed rotation.During turning, each spindle that is rotating 10 with the position thereon cop 16 and the ballooning of yarn 24 that is also rotating form eddy current shape air-flow (arrow S), except it since air attached to the tangential component that is produced on the parts that rotate, because act on the centrifugal force on the air, this eddy current shape air-flow also has radial component.This radial component depends on the diameter of the parts that rotating, the diameter of cop 16 especially, and increase along with the increase of diameter.Therefore, especially in the taper of cop 16 in yarn district 21 and at the lower end area place of its bag sigmoid, air flow has an axial component, this axial component is from pointing to than major diameter than minor diameter.Therefore, this axial component stretches from the top down and stretches from bottom to top in lower end area around the yarn district last, as in the accompanying drawings by shown in arrow SO and the SU.
In the process of the middle part of housing by the air in annular space 37 in suction inlet 26 ' suction housing 52, as shown by arrows, from top with below the air flow that enters the housing 52 supported by the axial component of air flow SO and SU.
So just guaranteed in fact not have air above housing 52 and below effusion, thereby can be collected in the heat that produces owing to the rotation of spindle 10, spool 14 and cop 16 in the zone of yarning part, and heat is along with the air of discharging is pulled away from the middle part by a suction channel, so this heat can not arrive in the spinning room of the spinning machine that aspirator of the present invention has been installed.
Directly collect and concentrated taking away by air guiding device on each yarning part and aspirator at the heat that each yarning part produces, so these heats do not need to adopt jumbo ventilation to discharge from spinning room in the place that produces heat.
According to another embodiment of spinning machine of the present invention, aspirator is determined according to the position of ring rail 19.
When spinning process begins, the cop height be very little and only the air in the lower region of spindle 10 carried and made secretly its motion.Therefore the heat that only need take away moving air and in this zone, produce, rather than the whole zone of spindle.In the yarn process, the cop height increases, and the air capacity of bringing rotation into is increased always continuous.Therefore the heat that is produced during the cop height increases is increasing, because such process, flow condition constantly changes.The basis of the embodiment that replaces of Fig. 7~14 is to consider that position and/or size by changing suction inlet can change flow condition and regulate the pumping power that the air suction especially is adjusted at the instantaneous height of cop.
For this reason, create a kind of aspirator according to Fig. 7, housing 52 is fixedly mounted on the ring rail and along with ring rail motion up and down together in the base.In according to the embodiment of Fig. 7~14, preferably become the internal diameter of the housing of cylindrical shape setting to want the big circular motion that does not also hinder ballooning of yarn to the motion that neither hinders the steel traveler 18 on the rings 17.
Because ring rail is arranged in the zone of spool 14 lower ends during beginning to spin, and compares with known spindle, spindle 10 need stretch between spool 14 and step rail 13, so ring rail 19 moves downward it and begins yarning position and can not be subjected to down shielded-plate tube 25 obstructions.In addition, when described aspirator is used in the spindle of belt drives, the following shielded-plate tube 25 of housing 52 need have at least two grooves 29, and these two grooves are located on the circumference with staggering each other, makes driving belt 12 can enter down the inner space of shielded-plate tube 25 in the clear.In the spindle of the drive unit that has oneself, can not adopt this measure.
Even the axial stretching, extension of housing device 52 in this embodiment also may be selected to full packages yarn 16 and also can surround by conductively-closed cover 52.
According to Fig. 7 and Fig. 8, in housing 52, be provided with flute profile outlet 26, this outlet is approximately a segment length of 40% of the length of spool 14 along one of length extending.
Comprise tube connector 34 and air guiding face 48,49 with 50 and the aspirator 27 of unshowned side air guiding face be provided with regularly and be designed to respect to spindle 10 and separate from housing 52.Following air guiding face 49 is chosen to make it to equal the height of suction inlet 26 with the distance of overhead gas guiding face 50.In addition, air guiding face 49,50 is arranged so that in the axial direction at ring rail and is arranged under its situation that goes up possible position most, and overhead gas guiding face 50 is positioned on the height of upper end of suction inlet 26, and following air guiding face 49 then is positioned at the height of suction inlet 26 lower ends.
This measure has guaranteed that hot-air can be pulled away, as shown in Figure 7 under the situation of the cop 16 of expiring yarn at least basically fully in the maximum open district.Also do not expire in the spinning state of yarn at cop 16, as shown in Figure 8, a part of suction inlet conductively-closed cover 52 covers, and therefore, suction occurs over just on less effective puff length.Thereby pumping power thereby can match with the heat that is produced with the cop height.In addition, the pumping power that increases along with the increase of cop height guarantee in the situation that has high heat to produce-promptly form at very high cop situation-produced and support the stack effect of updraft to be cancelled.
