Description
Technical field
The present invention relates to a kind of thread nipper assembly that is used for the spindle of spinning machine or twisting machine, have and be used for thread nipper assembly is installed to installing rack on the spindle, have two holders that are used for the clamping yarn of relative motion mutually, has at least one makes the holder closure with loading force loading element, with have the unloading element that at least one is used to produce the unload forces opposite with the loading force direction, wherein unload element and in thread nipper assembly, can when spindle rotates, under centrifugal action, move, and holder can be opened by unload forces.
Background technology
Such thread nipper assembly becomes prior art by document WO 2007/131562A1.The loading element that is used for the clamping yarn is formed by spring at known thread nipper assembly.The unloading element of a plurality of spherical formulas is set in this thread nipper assembly, and they can radially move and guide in the guiding mechanism of half hull shape formula.The guiding mechanism of ball is configured to make the holder of yarn in sphere diameter open and close when moving.When spindle rotated under running status, ball was subjected to the centrifugal force that the increase with the spindle rotating speed increases.Have a limit speed, the unload forces that is produced by ball under this limit speed equals the loading force of spring.When surpassing this limit speed, thread nipper assembly is opened.When spindle was braked, under the speed conditions that oversteps the extreme limit, the centrifugal force of ball was less than the loading force of spring, thus the thread nipper assembly closure.The open and close of the holder of thread nipper assembly is to take place under the same rotating speed.A kind of similar thread nipper assembly is also open by DE19628826A1.
By the known a kind of thread nipper assembly that starts described type of WO2007/065703A2, wherein the open and close of holder is carried out under different spindle rotating speeds.If if at the bottom of can carrying out yarn tube under the low spindle rotating speed volume and after spinning machine or twisting machine are reset yarn still under a high as far as possible spindle rotating speed, remaining fixed in the thread nipper assembly, to be convenient to change the cop that is supported on the spindle so, so-called doffing operation.This can realize with the thread nipper assembly of WO2007/065703A2.Opening under a high rotating speed of holder carried out in the boost phase of spindle, and on the contrary, closing under the low rotating speed of holder carried out in the decelerating phase of spindle.This performance of thread nipper assembly is to realize by the magnet that is provided as loading element.Magnet loads movable holder by its suction and clamping yarn thus.Since the suction of magnet along with and holder between distance increase and reduce widely, therefore opening thread nipper assembly needs very big unload forces, that is needs high spindle rotating speed.
Because magnet suction reduces when becoming big in the clamping gap, so chucking power also reduces, and the yarn of clamping thick more, and the degree that chucking power reduces is big more.But under thick yarn situation,, yarn requires in thread nipper assembly, to have stronger chucking power just owing to having higher breaking strength.This external magnet is an expensive component, and especially they must have high magnetic force and simultaneously must be insensitive to vibrating under this situation.
Summary of the invention
Task of the present invention provides a kind of improved thread nipper assembly.
This task is so solved, and promptly a unloading element is assigned at least two positions in thread nipper assembly, on this position, can produce different unload forces by the unloading element under the spindle rotating speed that can limit.
Since the unloading element according to its present position can limit with keep constant spindle rotating speed under apply different unload forces, therefore can provide a kind of under the first spindle rotating speed, opening and under the second spindle rotating speed different with the first spindle rotating speed closed thread nipper assembly.Because unload forces changes, therefore in thread nipper assembly, do not need magnet.The loading force of at least one loading element is can be than bigger under the state of holder closure under the state that holder is opened.The chucking power that can realize thicker yarn thus is greater than the advantage than the chucking power of fine yarn.Changing cop operating period, also can or twist thread thick yarn thus remains in the thread nipper assembly securely.However, all loading element can be formed by dog-cheap spring element.
In advantageous embodiments, stipulate, distributed a closure state of holder and an open mode of having distributed holder for a primary importance of unloading element, wherein can under the holder situation in closure on the primary importance, produce a low unload forces and under the holder situation of opening on the second place, produce a high unload forces by the unloading element to a second place of unloading element.This comparison the setting of spindle and keep carrying out under the constant rotating speed.The advantage of this embodiment is that holder is just being opened under the high spindle rotating speed and reopened under low spindle rotating speed in the decelerating phase in the spindle boost phase.When being in balance, unload forces and loading force realize the open and close of thread nipper assembly.Because the unloading element can have two positions that produce different unload forces in thread nipper assembly, therefore have two limit speeds, unload forces and loading force are balances under this limit speed.Advantageously, the unloading element can move to the second place from primary importance in order to open holder when surpassing upper limit rotating speed of spindle, and the unloading element can move to primary importance from the second place for the closed clamp gripping member when being lower than a lower limit rotating speed that is positioned at below the described upper limit rotating speed.Because it is the unloading element is being merely able to produce low unload forces on the primary importance under the spindle rotating speed that limits in advance, therefore oppositely say deductively, needs higher spindle rotating speed, big to enough overcoming loading force and making holder enter open mode up to unload forces.Unloading element in decelerating phase at spindle is positioned on the second place and correspondingly produces higher unload forces under identical rotating speed.Therefore under the not closed situation of holder, the spindle rotating speed can drop to until the lower limit rotating speed.Only when being lower than the lower limit rotating speed, unload forces just is lower than loading force and causes holder to be closed.
Imbalance on the spindle is advantageously arranged a plurality of unloading elements on the thread nipper assembly side face.Preferred unloading element is by can forming along the centrifugal body of radial motion basically.Centrifugal body is advantageously formed by ball.
In another embodiment of the present invention, advantageously, be that a centrifugal body has distributed at least two bearing-surfaces.The primary importance of first bearing-surface and centrifugal body matches and the second place of second bearing-surface and centrifugal body matches.Preferably, bearing-surface is positioned on the different radiuses, and this radius is by bearing-surface and be used for the spacing that thread nipper assembly is installed between the center line of the installing rack on the spindle is limited.Because centrifugal body radially moves to the second place and open holder in the case from primary importance, therefore advantageously, the bearing-surface that matches with primary importance is arranged on than on the less radius of the bearing-surface that matches with the second place.
Stipulate in another embodiment of the present invention, on the axial cross section of thread nipper assembly, see, between the center line of tangent line of being done on the contact point between centrifugal body and the bearing-surface and installing rack, has an angle, and on the bearing-surface that is positioned on the small radii, there is a tangent line, have a little angle between the center line of this tangent line and installing rack and on being positioned at, have a tangent line, have a big angle between the center line of this tangent line and installing rack than the bearing-surface on the long radius.Angle between tangent line and the center line has determined the unload forces of unloading element under identical centrifugal force.A kind of very simple thread nipper assembly can be realized by this embodiment, wherein under the spindle rotating speed that limits, different unload forces can be produced by the unloading element.With under the quality of centrifugal body is coordinated mutually, geometry that can be by bearing-surface with very simple mode make the high-low limit rotating speed with require suitable.Can not use expensive magnet.Can also cancel magnet is installed to additional installation steps in the thread nipper assembly.Therefore thread nipper assembly of the present invention also can hang down the manufacturing of expense ground in enormous quantities.
Advantageously, tangent line on contact point and center line intersect.Particularly preferably, tangent line is arranged in the plane of the axial cross section of installing rack.The centrifugal force that centrifugal thus body produces can very well convert the unload forces opposite with the loading force direction to.Advantageously, described little angle is between 0 ° and 20 °, is preferably especially in 5 ° to 10 ° scope.Described big angle advantageously is between 60 ° and 80 °, is preferably especially in 60 ° to 75 ° scope.
In another embodiment can be advantageously, a bearing-surface that is positioned on the small radii has a zone, and this zone is seen on axial cross section with the center wire clamp of installing rack and is become a little angle.One is positioned at than the bearing-surface on the long radius and has a zone, and this zone is seen on axial cross section with the center wire clamp of installing rack and become a big angle.The zone of linearly extended bearing-surface can be made very simply on axial cross section.And the unload forces that centrifugal body produces is constant on the linearly extended zone of bearing-surface basically, thereby can reduce the influence of manufacturing tolerance to the high-low limit rotating speed.In the bearing-surface that regional cathetus ground extends, the angle between bearing-surface and the center line just in time equals center line and centrifugal body and do angle between the tangent line on the contact point on the bearing-surface.
In order to guarantee the motion successfully diametrically of centrifugal body, advantageously, have a bearing-surface at the bearing-surface on the small radii with between than the bearing-surface on the long radius, the angle between this bearing-surface and the center line increases continuously along with the increase of radius.
Can be advantageously, bearing-surface that is used for centrifugal body is arranged on one of the thread nipper assembly parts that can be out of shape by action of centrifugal force.Centrifugal body and can have contact point by the parts of action of centrifugal force distortion can be made a tangent line on this contact point.The advantage of this embodiment is that during the spindle boost phase, the angle between the center line of tangent line and installing rack changes.Under low spindle rotating speed, the angle between tangent line and the center line is very little, thereby can take a high upper limit rotating speed to by this optional feature, and holder is opened under this upper limit rotating speed.This can preferably be formed by ring by the parts of action of centrifugal force distortion this moment.The mid point of ring is preferably placed on the center line of installing rack.This ring can advantageously be made by the material of caoutchouc elasticity.Preferably arrange this ring in this wise, make it when chucking power is closed, not hinder the motion of centrifugal body.

The specific embodiment
The spindle 1 of a spinning machine or twisting machine has been shown among Fig. 1.Spindle 1 is made up of the upper-part 2 and the non-rotary cartridge housing 3 of rotation, and cartridge housing is fixed on the step rail that does not illustrate still.Upper-part 2 has the axle 4 that together rotates with it, and this is bearing in cartridge housing 3 in the bearing of journals 5 and the end bearing that does not illustrate.Upper-part 2 comprises a wharve 6, and upper-part can drive with belt 7 by this wharve.
The top of wharve 6 is provided with thread nipper assembly 8.Thread nipper assembly 8 utilizes installing rack 9 to be installed on the spindle upper section spare 2.Thread nipper assembly 8 preferably removably is fixed on the upper-part 2, so that having under the problem condition and can easily change.Upper-part 2 can be settled a unshowned bobbin above thread nipper assembly 8, on this bobbin with the reel for yarn coiled yarn bobbin of producing.Winding process is implemented with liftable ring rail in known manner, and ring rail extends on a plurality of spindles 1 that are arranged side by side in the machine.Each spindle 1 all sets an also unshowned ring spinning, on ring spinning with the known manner steel traveler that going in ring, it at the run duration twist yarn and with the yarn guide yarn bobbin on.
By two guiding mechanisms 41 and 42 motions that guarantee at 12,13 o'clock sleeves 11 of open and close holder.In order to make accurately guiding on matrix 10 of sleeve 11, in the zone of holder 13, be provided with first guiding mechanism.Second guiding mechanism 42 is spaced apart away from first guiding mechanism, 41 ground as far as possible.Guiding mechanism 41 and guiding mechanism 42 are arranged so that loading element 17 and unloading element 18 are seen and are positioned between two guiding mechanisms 41,42 on axial cross section.For the undesirable imbalance on the thread nipper assembly 8 is minimized, spring 17 is led and is centered by matrix 10.
In addition, thread nipper assembly 8 comprises a plurality of unloading elements 18, and it is used to produce the unload forces reverse with loading force.Two unloading elements 18 have been shown in Fig. 1 and 2.A plurality of unloading elements 18 can be arranged on the side face of thread nipper assembly 8 evenly distributedly fully.Unloading element 18 is made of the centrifugal body 19 of the sphere that can radially move basically.This ball is preferably made of steel.
Be under the closure state shown in Figure 1 at clamping element 12,13, unloading element 18 is positioned on the primary importance.Centrifugal body 19 is directed in the guiding mechanism 20 in matrix 20.Centrifugal body 19 is equipped with first bearing-surface 21.Bearing-surface 21 is arranged on the sleeve 11.Ball 19 leans on bearing-surface 21 under the centrifugal action when spindle 1 rotation.Bearing-surface 21 presss from both sides into a little angle A with the center line 23 of installing rack 9.By this angle A, ball 19 produces the power of axial action on sleeve 11 along center line 23, and the direction of this power is opposite with the loading force of spring 17.If the spindle rotating speed surpasses a upper limit rotating speed, the power that is applied by ball 19 will be above the loading force of spring 17 so, thereby sleeve 11 moves towards the direction of wharve 6.By the motion of sleeve 11, clamping element 12,13 is opened.Ball 19 radially outwards moves on the second place than long radius in guiding mechanism 20 simultaneously.
In Fig. 2, can see the state of clamping device 8 when clamping element 12,13 is opened.Centrifugal body 19 is opened in the gap on the second place and between clamping face 14 and 15 16.On this position, centrifugal body 19 is equipped with second bearing-surface 22 on the sleeve 11, has an angle B between the center line 23 of it and installing rack 9.Angle B is greater than angle A.Except under the given spindle rotating speed by ball the centrifugal force that produces on this second place is slightly big because the spacing of ball and rotation 23 is big, ball 19 act on the sleeve 11 unload forces since angle B greatly than on primary importance greatly a lot.If reduce the spindle rotating speed now again, thread nipper assembly 8 also can be closed once more when low upper limit rotating speed so, and wherein thread nipper assembly 8 has been opened under upper limit rotating speed.Only when being lower than a lower limit rotating speed unload forces just be reduced to this unload forces be lower than spring 17 loading force degree and sleeve 11 is pushed up upward once more by spring 17.Loading element 17 makes holder 12,13 closures and ball 19 moves on the primary importance, referring to Fig. 1.
Fig. 3 shows once more enlargedly as the position around the ball 19 of unloading element 18.Can see that ball 19 leans on the guiding mechanism 20 of matrix 10 and lean on the bearing-surface 21 at sleeve 11.By the angle A between bearing-surface 21 and the center line 23, on the contact point 24 between centrifugal body 19 and the bearing-surface 21, form the unload forces opposite with the chucking power direction.Bearing-surface 21 has a zone of extending at the axial cross section cathetus.The angle A of bearing-surface 21 is placing the tangent line on the ball 19 identical with one thus on the contact point 24.Ball 19 leans thereon second bearing-surface 22 and is on the bigger radius of a ratio first bearing-surface 21 when thread nipper assembly is opened.Has a big angle B between second bearing-surface 22 and the center line 23.Angle B is more much bigger than angle A.Make thread nipper assembly 8 under high spindle rotating speed, to open by this differential seat angle, and only under low a lot of spindle rotating speed, just close again.
Process when for clarity, describing spindle 1 operation that once has thread nipper assembly of the present invention again according to time sequencing now.With during for example being 20000 rev/mins the running speed spinning or the process of twisting thread carried out, thread nipper assembly 8 is opened.Be empty in the gap 16.Yarn is winding on the bobbin on the upper-part 2 that is positioned at spindle 1.Changing before the spool operation of a bobbin full or full spool, ring rail is moved on the position, with rings so that yarn inserts in the gap 16 with the bobbin change of sky.When this so-called underwinding operation (binding foot) of yarn, the rotating speed of spindle 1 is reduced.Be lower than lower limit if the spindle rotating speed is reduced to, thread nipper assembly 8 is with regard to closure and underwinding is clamped between clamping element 12 and 13 so.Spindle is stopped and full spool is upwards pulled out from upper-part 2.When pulling out full spool, keep being clamped in the thread nipper assembly 8 and yarn is separated between spool and thread nipper assembly 8 from the yarn end of drafter or delivery roller.After the bobbin with a sky installs on the upper-part 2, start the machine once more.Upwards run to a position again at 1 accelerating period of spindle ring rail, made yarn be winding to be placed on the bobbin above the upper-part 2.If the spindle rotating speed surpasses a higher limit, the yarn end that is clamped in the gap 16 with regard to opening once more of thread nipper assembly 8 is thrown out of so.In order to guarantee that changing operating period at spool moves safely and reliably, be provided with the lower limit rotating speed very low,, be favourable for example at about 1000 to 2000 rev/mins order of magnitude.When underwinding is inserted in the gap 16, importantly, yarn is in the gap 16 really on the one hand, so that can be by clamping reliably, should be when but yarn twines the matrix 10 of thread nipper assembly on the other hand greater than 360 °, so that can also from holder 12 and 13, split out at an easy rate after the yarn end.If the spindle rotating speed is as far as possible little, can more accurately and more easily underwinding be twined in the gap 16 so.Therefore, thread nipper assembly 8 can closure be important under as far as possible little lower limit rotating speed.On the contrary, at the spindle boost phase, being positioned under the high as far as possible limit speed if thread nipper assembly is opened present upper limit rotating speed once more, under 10000 rev/mins the order of magnitude, then is very favorable for example.The termination that is clamped in the underwinding between holder 12 and 13 is remained in the thread nipper assembly 8 enough number of turns of having reeled thus reliably always on the bobbin at sky.Operational failure that reduces widely thus and broken yarn.
In order further to optimize thread nipper assembly 8, can change the planform of bearing-surface 21 and 22.Several favourable modification have been shown in Fig. 4 to 8.
In the modification of Fig. 4, between bearing-surface 21 and bearing-surface 22, there is a position, the angle of this position 25 and center line 23 is between angle A and angle B.22 transition improves from bearing-surface 21 to bearing-surface to make ball 19 by this bearing-surface 25.Another improvement to the guiding of ball 19 can realize by following measure, a bearing-surface 26 is being set at the bearing-surface 21 on the minor radius with between the bearing-surface 22 on the long radius, and the angle between this bearing-surface and the center line 23 is along with the increase of radius becomes big continuously.So rounded bearing-surface 26 is shown among Fig. 5.
Figure 6 illustrates a favourable modification, wherein bearing-surface 21 and bearing-surface 22 have been bent.Can realize a kind of mild especially transition of ball 19 thus.The position of ball 19 under the thread nipper assembly situation of closure has been shown in the left part of Fig. 6.The right side part of Fig. 6 shows the ball 19 under thread nipper assembly 8 situations of opening.Under bearing-surface 21 situations of bending, the angle A between the tangent line on the contact point 24 27 and it and center line 23 plays decisive action to the unload forces that is produced by ball 19.Even be positioned on the bearing-surface 22, also be that the angle B by a tangent line 28 on the contact point between ball 19 and the bearing-surface 22 plays a decisive role at ball 19 under the situation that thread nipper assembly 8 is opened.
Because the bearing- surface 21 and 22 among Fig. 3 to 5 has linearly extended zone, therefore the tangent line 27 and 28 there overlaps with the surface of bearing-surface 21 and 22.Angle A preferably in the scope between 5 ° and 10 °, is preferably about 6 ° especially.Angle B in 60 ° to 75 ° scope, especially is about 65 ° advantageously.
Bearing-surface 21 has a slight protuberance in the modification shown in Fig. 7, has very little angle A thus between tangent line on the contact point 24 27 and center line 23.Therefore can realize a higher upper limit rotating speed for opening of thread nipper assembly.
In Fig. 8, the sleeve 11 of thread nipper assembly 8 contains the parts 29 that can be out of shape under centrifugal action.The bearing-surface 21 that leans thereon at centrifugal body 19 under thread nipper assembly 8 closure states is arranged on these deformable parts 29.Between tangent line on the contact point 24 27 and center line 23, also has a little angle A.Deformable parts 29 are advantageously formed by ring 30.The mid point of ring 30 is positioned on the center line 23 of installing rack.Ring 30 is made by rubber elastic material.Ring 30 makes thread nipper assembly 8 just open when high upper limit rotating speed.The spindle rotating speed must be high to making ring 30 enlarge under centrifugal action and making ball 19 can change its position thus.In 1 decelerating phase of spindle, deformable parts 29 not stymie 19 move to primary importance from the second place.By correspondingly arranging ring 30, in form of implementation shown in Figure 8 even the angle A of tangent line 27 can be reduced to negative value, thereby when boost phase begins, centrifugal body 19 strengthens holder 12,13 chucking power and further improve the clamping action of thread nipper assembly 8 thus is especially under thick thick yarn situation.Increase gradually and encircle 30 gradually under the spread scenarios at the spindle rotating speed, it is big that angle A continues to become, and moves at last up to ball 19 to surpass ring 30.
In the form of implementation shown in Fig. 1 to 8, sleeve 11 is at the diameter of its stroke of being implemented in for the axially-movable that opens and closes gap 16 less than ball 19.Have bigger stroke or will use littler ball 19 if wish sleeve 11 now, the special matched of the guiding mechanism 20 of ball 19 in the matrix 10 of thread nipper assembly 8 is favourable so.
An embodiment of thread nipper assembly 8 has been shown in Fig. 9 and 10, and the stroke of its middle sleeve 11 is greater than the diameter of ball 19.Also the embodiment with Fig. 1 to 8 is the same, and sleeve 11 is provided with two bearing- surfaces 21 and 22, and they have different angle A and B with center line 23 diameters of spindle 1.Bearing- surface 21 and 22 is arranged on the radially inwardly prominent gripper shoe 51.Gripper shoe 51 protrudes in the groove 52 of matrix 10.Gripper shoe 51 is so arranged, makes ball 19 therefrom supported in the heart.The guiding mechanism 20 of ball 19 is such structure in matrix 10, make ball 19 by two fan-shaped spigot surfaces 53 guiding and the view that can be similar to Fig. 2 radially from shown in primary importance move to the second place.Spigot surface 53 is by some local formation of a cylindrical side face.As can clearly seeing among Figure 10, guiding mechanism 20 and bearing- surface 21,22 are arranged symmetrically with respect to ball center.Ball 19 is very accurately led thus, thereby can not block during along radial motion at it.
The embodiment of the bearing-surface shown in Fig. 3 to 8 21,22 can certainly be applied in the form of implementation shown in Fig. 9 and 10.
