The present invention relates to spinning machine, especially have the ring spinner that sets a plurality of spinning positions in a row.This spinning machine includes drivable spindle, spool is arranged on the spindle, the yarn that is spun into is the coiled cop on spool, each spindle has a twisting generating apparatus, this twisting generating apparatus can be along its axis with respect to the spindle reciprocating motion, and determined one around the yarn district for yarn on the cop on the spool or on the spool, one dividing plate surrounds spindle basically fully around the circumference of spindle, and between cop that forms on spool or the spool and dividing plate, form an annular space, dividing plate is at least so far away along axially extending up or down of spindle, so that the epimere of full packages yarn and hypomere surround by dividing plate at least basically continuously, suction pipe is connected at least one suction inlet with the pressure source that is lower than atmospheric pressure and dividing plate.
In the spinning process of this spinning machine, spindle has high rotating speed, can reach 25000 rev/mins, and is perhaps more.Because spindle is carried the surrounding air around cop secretly, so, strong turbulent flow and air-flow produced around spindle.The friction of air makes the zone heating significantly around spindle, because a large amount of spindles, this has caused the rising of the spinning room temperature that can not ignore.And on the other hand, because predetermined constant temperature is very important to good yarn qualities, so must carry out air conditioning to whole spinning room, this needs lot of energy.
Yet, also known from regional directly suction air around spindle.
In a known suction equipment (DE-U1777265), a lid is set below the ring rail that carries rings and steel traveler, this lid surrounds the spindle and the cop of formation thereon.An annular space that forms between lid and cop is connected to a Yarn break suction system, and it forever or temporarily takes away the impurity that is deposited in the lid.The air-flow that carries out this ways of connecting and generation is all unexposed.
In the known ring spinner that has suction equipment (DE-GM1936437) of another kind, anti-balloon plate is arranged on the ring rail between each spinning position.The tubulose lever jack that is used for anti-balloon plate is arranged in the zone of each rings and has opening as suction nozzle, links to each other with the center of spinning machine by a conduit.Plan to take away the fine hair that a plurality of spinning positions place in the zone of rings produces in such a way.
Know another ring spinner from Japanese patent application 48-52916, wherein, a pipe that forms cop is thereon surrounded by a tube that fixedly installs with respect to this pipe.A rings that is arranged in the tube is connected on the ring rail by a bridge, and this bridge extends through an axial groove in the tube.
In centrifugal (jar) formula twisting mill, known to from DE1685890C3, the tophan box of spinning position is surrounded by rigid cylinder shape sleeve, and thus, a labyrinth gland is set between the lower end and tophan box of described sleeve.One suction device is arranged on the upper end of the sleeve in the zone of a rings, and rings is arranged on the tophan box, and this suction device is connected on the center suction pipe of centrifugal (jar) formula twisting mill.Yet a high proportion of surrounding air sucks by the suction device of described upper end.
Known that from DE-AS1510717 being used for the ring spinning twisting mill carries out dedusting or keep rotating spindle and the yarn cleaning, wherein, cylindrical tube is extended on the length of cop.This pipe at two ends be open and allow air axially to enter from lower and upper.The air of bringing into from spindle and position cop is thereon tangentially discharged through a side opening.In this way, heat directly is discharged in the spinning room.
Known a kind of two-for-one twister from ED2544643B2, wherein, each adds twist spindles and is surrounded by an air ring cover.One upper limiting wall and a lower limit wall on the whole width of this two-for-one twister and length on the air ring cover and below extension.The sidewall that is connected on upper limiting wall and the lower limit wall is set on two vertical lateral surfaces of the machine of air ring cover outside.The conduit of Xing Chenging links to each other with the suction device like this.A suction inlet is arranged in the last zone of air ring cover, and surrounding air also sucks through suction inlet.
The objective of the invention is to create the spinning machine of top described type now, prevent effectively that with minimum suction the heat that produces at the spinning position place from entering in the spinning room, and guarantee to discharge fully basically this heat.
In the spinning machine of the above-mentioned type, dividing plate is equipped with the hole at the vertically several at least stations place along spindle, thereby so suction inlet on quite long a section of spindle height, extend and reached purpose of the present invention.
Each spinning position in a ring spinner can be counted as one radially or axial ventilator, and it rotates air between cop and dividing plate.Except such primary air, because the conical upper of cop is divided and following bag shape partly produces the axial flow that increases the zone towards the reel for yarn diameter, so produced secondary airflow.Dividing plate arranged according to the present invention and provide at least one suction inlet to guarantee total air-flow of carrying by secondary airflow central region to dividing plate.Air is taken away by the suction device from this zone, and any air that has arrived the dividing plate equipment region can face upward or downward effusion.Particularly, this guarantees that the heat that produces is pulled away with air in a concentrated manner in the spinning position zone except fibre fluff, so, said heat can not be discharged in the spinning room, if this heat has to discharge by air one regulating system costliness and large-scale or analog in this spinning room.
So, thought of the present invention is to be arranged in such a way a suction device, make at spindle and the pipe that on the cop that forms on the spindle, is provided with and always be covered and be closed, and in the central region of dividing plate, provide suction, therefore, one air-flow, perhaps form in dividing plate or in the annular space between pipe or cop and dividing plate towards the air-flow of two bursts of switched in opposite at middle part in an embodiment according to the present invention, these air-flows are collected in the heat that the there produces, and this heat is pulled away in a concentrated manner through suction then.The main advantage of this suction is that two strands of air-flows are against each other carried by the axial flow component of secondary airflow, and this secondary airflow to be geometry owing to the cop that is forming produce, like this, allow suction to remain on very low level.
In better embodiment of the present invention, effectively discharge length and be at least 20% of length of tube.
In another better embodiment, dividing plate fixedly installs with respect to spindle.Here, the suction of air is carried by wall attachment effect in addition, because wall attachment effect, is tending towards keeping it near described wall along the air-flow of a wall.So, be carried on the axial height of the suction inlet of bulkhead sides opening around the air discharge currents that spindle radially rotates.This effect also helps to reduce suction.
By the production cost that provides the dividing plate that is wholely set and suction pipe can reduce the suction device.
The characteristics of another better embodiment are that dividing plate is furnished with rotatable and/or mobilizable lid in the front side.This is easy near cop or spindle when making Operation and maintenance equipment.
Because at dividing plate internal support and mobile twisting generating apparatus, especially the rings in the ring spinner/steel traveler device is problematic, further better among the embodiment second groove that in axial direction extends is being set, by this groove, a fixture of supporting twisting generating apparatus enters the inner space of dividing plate.The length of this groove is chosen such that promptly, and the twisting generating apparatus is moved on the highest order from lowest order according to the needs that cop forms.Preferably adopt sealing gasket in order to seal this groove,, can prevent that air and heat from escaping into spinning room through described groove by means of sealing gasket.
Be used to support another embodiment of twisting generation equipment, it is characterized in that, the U-shaped fixture is set, thus, an end that is positioned at a pillar of spacer assembly outside is connected on the rings panel seat, second pillar that the one end connects the twisting generating apparatus be positioned at dividing plate below, and connect two pillars part in addition the uppermost position in fig-ure place of twisting generating apparatus still be in dividing plate lower limb below or even still be in above the top edge of dividing plate at the upper/lower positions place of twisting generating apparatus.Being provided with like this allow to omit admitted the groove of the fixture that is used to twist generating apparatus, prevented also that therefore air from overflowing through described groove.Be preferably, can be provided with like this that the groove of fixture that the air guide face is used in the twisting generating apparatus can be positioned at a side and suction inlet is positioned at opposite side.The air of taking away imports to connection mouth by the air guide plate.In this embodiment, the other air guide face of two adjacent spindles can be provided with best one mode, so the air of taking away from two spindles can be imported into a connection mouth.
In another better embodiment, the dividing plate of the spindle of adjacent setting can be at least in part to be wholely set.This helps to reduce the complicated of production process and reduces production costs thus.
In yet another embodiment of the present invention, dividing plate with respect to spindle for movably.Yet, with respect to twisting generating apparatus for fixedly installing.Because the mobility of dividing plate, the suction inlet that can effectively discharge air changes with its position and/or size, therefore considers, can greatly change the flow condition in the annular space between spindle or cop that is forming and the dividing plate during cop forms.In this respect, it should be noted that the air that is heated by rotation causes the pile up effect of carrying downdraught, this pile up effect can be of different sizes according to the cop size.
In the of the present invention better embodiment that provides, suction inlet be directly arranged in below the ring rail or above, perhaps several suction inlets evenly are set, so that utilize axial component particularly well towards the air-flow of the thicker end of cop around ring rail.
Because for fixedly installing, fix with respect to the twisting generating apparatus, also can consider the variation of flox condition during cop forms by dividing plate with respect to spindle for suction pipe.This caused during cop forms and in up and down between moving period of twisting generating apparatus, the variation of suction inlet, and this exerts an influence to suction.Therefore, in spinning process, spinning process begin suction is added on the reduced levels of spindle, and, along with spinning process continues, suction is increased to gradually on the whole zone of spindle.Like this, suction is adjusted on the heat of the height of cop and generation.One preferably among the embodiment, connection mouth and air guide face fixedly install like this, make the twisting generating apparatus when being in the possible position of going up most they axially and the upper limit of at least one suction inlet or lower limit in line, guarantee in the cop that is spun into fully, on the total length of suction inlet, to carry out exactly suction.
In another better embodiment of the present invention, between dividing plate and suction pipe, spacer assembly is set, have at least one passage and more or less suction pipe is connected on the suction inlet in dividing plate according to the ring rail position.More or less firmly cover according to ring rail position suction pipe, like this, cause suction to depend on the position of twisting generating apparatus by spacer assembly.
When spacer assembly has two passages that are connected on the axially movable opening,, also can guarantee in this embodiment suction is added in the zone of the cop that is forming according to the ring rail position.Particularly, the several suction inlets that are provided with in a certain distance apart from one another around circumference in dividing plate can be joined together by the passage in the spacer assembly, like this, guarantee more uniform suction.
Suction can realize by means of a flexible pipe or a shared suction pipe under all described situations, and the air that this pipe will have been discharged by the center suction pipe takes in the center suction system of spinning machine separately.
These and embodiment further qualification in the dependent claims preferably in addition.

As shown in Figure 1, the spinning position of ring spinner has 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 extends (not shown more details) and carries a plurality of spindles 10 on the 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, spinning position has 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 has rings opening 20 in rings 17, and spool 14 and the cop 16 that forms thereon extend by this opening 20.
According to Fig. 1 and 1a, suction inlet 26 ' be provided with as a groove, and in this embodiment, its length approximates 45% of spool 14 length.In general, suction inlet 26 ' the length I, be effectively when taking air out of, should equal 20% of spool length at least.
According to Fig. 1 b, also the axle upwardly extending one narrower groove of spindle 10 in the above and below be connected to flute profile suction inlet 26 ' on.
In the embodiment that each illustrates in succession, suction inlet 26 also can be made up of several openings that distribute by the axial interruption of spindle 10, shown in the example among Fig. 6.
Have cop 16 at spindle 10(on it) and dividing plate 52 between the annular space that forms by suction inlet 26 ', air guide surface 48,49 and 50, and the space and the connection mouth 34 that are limited by side direction air guide surface (not shown) are connected on the suction pipe (Fig. 1 is not shown).
The top view of Fig. 2 illustrates the possible cross section shape of dividing plate 52.Forward part at dividing plate 52 has a lid 46, and this lid rotatably is provided with so that the operator is easy near cop 16 or spindle 10.
In practice, be supporting ring rail 19, it is problematic that dividing plate 52 seals on circumference fully.For this reason, in dividing plate 52, be provided with an axial groove 64, can enter by fixture of this groove in the interior space of dividing plate 52 so that supporting ring rail 19, and this fixture be connected on the ring rail carriage 36 that is located at dividing plate 52 outsides according to Fig. 3 and 4.In dividing plate 52, have fixture of making 62 and move to a length on the spinning process desired position by the axially extended groove 64 of spindle.According to Fig. 3, groove 64 is arranged on the direction relative with the suction device 27 that comprises connection mouth 34 and air guide face 48,49,50.Yet, can be arranged on any position on the circumference, especially near suction device 27, as shown in Figure 4.
For the annular space 37 of seal diaphragm 52, on groove 64, can be provided with a sealing gasket 60, be preferably the overlap joint elastic sealing gasket.
For avoiding setting up the embodiment that groove 64 provides Fig. 5, wherein, fixture 62 is arranged to U-shaped.Be arranged on the overhang bracket ring rail 19 of the pillar in the annular space 37 of dividing plate 52 to small part, and the end that is located at second pillar of dividing plate 52 outsides is connected on the ring rail carriage 36, this carriage 36 spindle 10 axially on can move up and down.Pillar, especially in the length of pillar select like this so that when ring rail is in its uppermost position in fig-ure the coupling part of two pillars still be positioned under the lower limb 32 of dividing plate 52.
According to Fig. 6, the dividing plate 52 of two adjacent spindles 10 can be provided with adult at least partly.The side of the dividing plate relative with protecgulum 46 has the upwardly extending groove of axle at spindle, this groove by another air guide face 58 separately, be formed for fixture 62 and suction inlet 26 ' groove 64.The air guide face is provided with like this, that is, make in the connection mouth 34 that air imports with a center suction pipe (not shown) links to each other of discharge.The air guide face of two adjacent spindles 10 is integral setting, so a connection mouth 34 is used for two spindles 10.In holddown groove 64, on the other hand, provide sealing gasket 60 in case the contact between stop ring shape space 37 and the spinning room.The fixture 62 of supporting ring rail 19 is connected on the ring rail carriage 36 by means of Connection Element 54 and bolt 56.
In the embodiment according to Fig. 6, the tail end of dividing plate 52 forms a side direction air guide face relative with additive air spigot surface 58, and this side direction spigot surface has been determined the flow direction of the air that is sucked away.
At the spinning machine duration of work, spindle 10, spool 14 and the cop 16 that forms on spool are with up to 25000 rev/mins or higher high-speed rotation.During turning, the spindle 10 of each rotation with the position thereon cop 16 and the air ring that rotates form eddy current shape air-flow (arrow S), except its tangential component (producing) because air adheres to the parts of rotation, because act on the centrifugal force on the air, this eddy current shape air-flow also comprises radial component.This radial component depends on the diameter of rotatable parts, especially the diameter of cop 16 and when the increase of its diameter also along with increase.Like this, especially, in yarn district 21 and at the lower end area place of its bag sigmoid, air flow has an axial component in the taper of cop 16, and this component points to major diameter from minor diameter.Therefore, this axial component extends around the yarn district from the top down and at following petiolarea from bottom to top last, as being represented by arrow SO among the figure.
In the process of the air of the annular space 37 by a suction inlet 26 ' in a middle region of dividing plate suction dividing plate 52, as shown by arrows, from top with below the air-flow that enters the dividing plate 52 carried by the axial component of air-flow SO and SU.
Like this, guarantee in fact not have air above dividing plate 52 and below effusion.Thereby, the zone that can be collected in spinning position is interior because spindle 10, the rotation of spool 14 and cop 16 and the heat that produces, and heat is along with the air of discharging is pulled away from the middle part by a suction pipe, so this heat can not arrive in the spinning room that the spinning machine that has suction device of the present invention has been installed.
The heat that produces at each spinning position is collected in a concentrated manner and is pulled away by means of air guide system and suction device at each spinning position place in the place that produces heat, and the effect of Chan Shenging is no longer to need by moving a large amount of air heat to be discharged from spinning room like this.
Another embodiment of spinning machine determines the suction system according to the position of ring rail 19 according to the present invention.
When spinning process began, the cop height was very little and only carries the air in the lower region of spindle 10 secretly and make its motion.Like this, the only heat that 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 continuous, and the air of rotation is increased.Like this, the heat that is produced during the cop height increases increases.Because such spinning process, flow condition constantly changes.The basis of the embodiment of the variation of Fig. 7～14 is to consider that position by changing suction inlet and/or size can change flow condition and regulate suction especially to the suction power of the instantaneous height of cop.
For this reason, createed a suction device according to Fig. 7, wherein, dividing plate 52 is rigidly fixed on the ring rail and along with ring rail moves together up and down.In according to the embodiment of Fig. 7～14, preferably become the internal diameter of the dividing plate that cylindrical shape is provided with big like this, make the motion of the steel traveler 18 that can not hinder on the rings 17 can not hinder the circular motion of air ring.
Because ring rail is arranged in the zone of spool 14 lower ends during beginning to spin, compare with known spindle, spindle 10 must extend between spool 14 and step rail 13, and therefore, ring rail 19 moves downward it to begin yarning position and not hindered by isolated tube 25.In addition, when described suction equipment was used in the spindle of belt drives, another isolated tube 25 of dividing plate 52 must have at least two grooves 29, and these two grooves are positioned opposite to each other on circumference, and rotating band 12 can enter down in the interior space of isolated tube 25, and can not be obstructed.In the spindle of the drive unit that has oneself, can not adopt this measure.
The axial elongation of spacer assembly 52 also can be selected so in this embodiment, that is, full packages yarn 16 also can be surrounded by dividing plate 52 even.
According to Fig. 7 and 8, flute profile outlet 26 is arranged in dividing plate 52, a segment length that is approximately spool 14 length 40% is extended in this outlet.
Comprise connection mouth 34, air guide face 48,49 with 50 and the suction device 27 of side direction air guide face (not shown) fixedly install with respect to 10 one-tenth on spindle and separate with dividing plate 52.The distance of following air guide face 49 and last air guide face 50 has been chosen to make it to equal the height of the upper end of suction inlet 26.In addition, air guide face 49,50 axially is provided with like this, that is, in the ring rail that is arranged at the uppermost position in fig-ure place, last air guide face 50 is positioned at the height of the upper end of suction inlet 26, and following air guide face 49 is positioned at the height of suction inlet 26 lower ends.
This measure guarantees that hot-air can be pulled away in the cop 16 that is spun into fully basically at least in the maximum open district, as shown in Figure 7.In the spinning stage that cop 16 does not also have so to be spun into fully, as shown in Figure 8, a part of suction inlet 26 is covered by dividing plate 52, and therefore, suction occurs over just on little effective suction length.The heat that suction power can adapt to the cop height and be produced.In addition, the suction that increases along with the increase of cop height is guaranteed that promptly produced when very high cop forms during having high heat to produce and the pile up effect supporting updraft is cancelled.
In the embodiment according to another variation of the suction device of Fig. 9, the diameter on the top 22 of spacer assembly 52 is greater than the diameter of bottom 25.In the present embodiment, the dividing plate of being made up of top 22 and lower part 25 52 also becomes to fixedly install with respect to ring rail 19.Under ring rail 19, promptly under the twisting generating apparatus that is formed by rings 17 and steel traveler 18, a circular suction inlet 26 is connected on the suction pipe 28 by connection mouth 34.Be connected to the suction pipe 28 on the ring rail 19, for example, as shown in Figure 9, extend at a plurality of spinning positions upper edge ring rail 19, each spinning position has the following isolated tube 25 with suction inlet 26.Each suction inlet 26 links to each other with suction pipe 28 through connection mouth.
