Description
The present invention relates to a kind of thread feeder, especially but not only be used for yarn is flowed to the thread feeder of weaving loom, especially knitting machine.
Background technology
Thread feeder is known, for example sees DE 19726027 A1.In the disclosed therein structure, thread feeder has retainer, and it is attached as the ring support that is called the machine ring.The latter is positioned at the annular knitting machine upper area and holds a plurality of thread feeders.Each retainer has vertical opening by it, two ball bearings is set to support vertical axis in opening.At this upper end, two belt pulleys are rotatably supported.But be arranged on vertical movement between the belt pulley, can manually operated tie-plate be used for optionally will going up or down belt pulley be fastened firmly to axle go up with its corotation.The thread feed wheel is arranged on the lower end of axle.Axle supports threaded short extension at its lower end, and the nut that the thread feed wheel is fixed to axle is supported in the extension.
Similarly thread feeder is open in the utility model of the Taiwan of application number 84206476.For the thread feed wheel is fastened to vertical axis, the latter is provided with threaded blind hole at its place, end, and wherein machine screw is axially supported to keep the thread feed wheel.
Consider that a large amount of yarn qualities always can be by device manufacturers prediction, the thread feed wheel always presents the trading off more or less of cooperating with various yarns about them as can be known.Because this situation wishes to regulate the thread feed wheel according to yarn qualities.For this reason, EP 0285828A2 discloses and has had dismountable thread feed wheel that draws the yarn element.
Also know,, need sometimes yarn is wound on the thread feed drum in the quiescent period of knitting machine.In order to make this feasible, DE 3042989A1 proposes, and between axle and thread feed wheel releasable clutch is set.When breaking away from, clutch allows the thread feed wheel to rotate freely and axle is static.
The object of the present invention is to provide a kind of thread feed wheel, it adapts to various yarns and yarn type in simple mode.Also wish to handle as far as possible simply thread feeder.
Thread feeder according to the present invention it axle and its thread feed wheel between have coupling arrangement or jockey, described coupling arrangement or jockey optionally have engagement state and released state, in engagement state, thread feed wheel anti-rotation is connected with this axle and is supported by this axle; In released state, the thread feed wheel shifts out from this axle.This can dismantle the thread feed wheel in simple mode by discharging coupling arrangement, and for example changes them with other thread feed wheel.Because coupling arrangement can be by can manually operated device manipulation, the replacing of thread feed wheel is a simple possible, and operation that wherein can manually operated equipment does not need the part of instrument and its formation coupling arrangement.Thereby, change the thread feed wheel without any need for the instrument of type.Especially, do not need to use spanner or screwdriver that coupling arrangement is changed to released state from engagement state, vice versa.
Thereby the different yarns that can standbyly be suitable for different yarns is fed to wheel to be installed on the thread feeder as required.Different thread feed wheels can have identical or different diameter, surface properties, surface texture, shape etc.Thus, thread feeder can adapt to large-scale yarn and condition, for example amount of thread of Xi Wanging and yarn tension.The dismounting and the replacing of thread feed wheel can manually be carried out.If particularly coupling arrangement belongs to from design centrally, this is especially true.Thus, pull down and be connected to once more when spool last, guarantee its true(-)running and without any need for further step when previous thread feed wheel.This centering equipment that also can be used in effect between axle and the thread feed wheel is realized.Centering equipment can form the part of connecting device.
Between its engagement state and released state, coupling arrangement can preferably have the intermediateness that is called loosening state, wherein, though coupling arrangement keeps the thread feed wheel with either large or small end play on axle, connects without any anti-rotation.In other words, at loosening state, axle and thread feed wheel can relative to each other rotate freely or rotate with little power.For example, under this state, yarn can for example manually be wound on the thread feed wheel.In case yarn is penetrated thread feeder, yarn at first is conducted through and is arranged on the guide eyelet before the thread feed wheel and is placed on then on the thread feed wheel.Thereafter, yarn clips on the bottom or edge of thread feed drum by operator's finger.In addition, coupling arrangement moves to its loosening state.In certain embodiments, this can realize by keeping yarn ground to go up from promptly applying axial compressive force down to the thread feed wheel simultaneously.So can manually twine a few commentaries on classics yarns.When a few commentaries on classics yarns are on thread feed wheel, in most cases no longer need manually or alternate manner keeps firm with yarn.Yarn is around being attached to each other, thereby prevents that them from coming off.Then, rotating this thread feed takes turns just enough.Have been found that from ergonomics, apply force to from bottom to top that thread feed wheel is gone up and simultaneously rotary yarn feed and give wheel easier.Thereby, by upwards or radially outer power realize that be favourable with coupling arrangement generally from the scheme that its connection status becomes loosening state.The answer of coupling arrangement can realize by the counter motion of the handle that is used to accordingly with opposite direction handle or by handling independent relieving mechanism.
In order to be beneficial to the winding of yarn, on the lower limb of thread feed wheel, make hook, lax yarn ends should be placed by hook.For winding yarn, free end is positioned in the hook and is preferably clamping securely.By rotating loosening thread feed wheel, yarn is wound thereon.After obtaining these, yarn is removed and is guided by the yarn eyelet from hook.
In all preferred embodiments, transferring to loosening state from engagement state preferably can be by can carrying out by manually operated equipment, and need not any instrument.
Can be preferably with singlehanded motion manipulation by manually operated equipment.For this reason, can preferably have handle by manually operated equipment, handle is by axially, radially and/or circumferentially locating movably with respect to axle.Be used for coupling arrangement from engagement state transfer to distance that the handle of released state passes by be preferably very little, thereby do not need to unclamp handle this operating period operator.Under the situation of the necessary circumferential movement of handle (promptly rotating), the anglec of rotation of process is preferably less than 180 °.Operation in this mode is simple especially, and the replacing of thread feed wheel can be carried out especially apace.
Coupling arrangement is preferably has braking equipment, and it for example can be used for the thread feed wheel is remained on axle.For example, braking equipment makes that the thread feed wheel is maintained on the axle and thereby does not come off from axle when the state of becoming flexible.Should or other braking equipment can with can be connected by manually operated equipment, thereby engagement state and released state with and/or all keep at loosening state can manually operated equipment.Thus, the operator can switch to another state with coupling arrangement from a kind of state in some way, and coupling arrangement is maintained in this state then.
The braking equipment of mentioning makes that the thread feed wheel is held when its loosening state.It can also be used for thread feed is coupled to axle with taking turns anti-rotation.For this reason, the connector that form fit connects and power transmission connects or clamping connects (being also referred to as friction connects) is feasible.The latter has such advantage, can be connected to each other at each relative position thread feed wheel and axle.In order to obtain the angle correspondence for engagement state between axle and thread feed wheel, the operator does not need to take any measure.
Replacedly, can with can manually operated equipment towards the flexibly precompressed of engagement state of connection device.In this case, as long as coupling arrangement rests on loosening state, can must keep securely by manually operated equipment.This embodiment has such advantage, and thread feed wheel keeps wittingly and do not have a driving.In case the operator removes from thread feeder, coupling arrangement presents engagement state.

With reference to figure 2, axle 11 is connected with thread feed wheel 10 by coupling arrangement 16, and coupling arrangement 16 is connected to axle 11 and centering on axle with thread feed wheel 10.
Shown in Fig. 2 was further, thread feed wheel 10 can be the curved part of deep draw plate.In this case, it for example has the edge 17 that stretches out at the top, and the edge 17 that stretches out has circular cross section and formation is drawn yarn section 18, and also is tapered to being preferably the yarn section 19 of depositing with non-circular cross sections taperedly.Deposit yarn section 19 by oblique outer outstanding edge 20 adjacency, edge 20 formations are preferably the yarn section with circular cross section.The wall of thread feed wheel 10 extends as the radially inner flange in a plane approx and thereby forms the bottom 21 that is preferably the plane from the yarn section.The bottom has big opening, and coupling arrangement 16 is arranged in the opening.The edge of opening has protuberance, and the radially built-in end face of protuberance is positioned on the circular arc.The diameter of circular arc is corresponding to the external diameter (except very little radial clearance) of hub 31, and hub 31 is described after a while.Cooperate by this, guarantee thread feed wheel 10 centerings with respect to axle 11.Thereby protuberance constitutes the centering protuberance.
Coupling arrangement by constitute by elastomeric material, preferably the curved part of plate that constitutes of thin spring steel plate is made, and preferably has the elastic bottom 22 that constitutes spring.Bottom 22 forms by the central plane part 23 of circular contour, and flat truncated cone part 24 outwards is connected on the described part 23.Part 23 is got in touch ground with external margin 20 in case of necessity, forms handle H, and as described later, by means of handle H, coupling arrangement 16 can be transferred to loosening state from its engagement state.
Single, short protuberance 25,26,27,28 external margins from part 24 extend radially outwardly and 21 overlap joint bottoms, positions 21 with above-mentioned centering protuberance in the bottom just in time.Form a plurality of folders and refer to 29,30 between protuberance 25 to 28, folder refers to that 29,30 at first bend being supported in the inboard of bottom 21 and extending with roughly axial direction then, thereby they extend between the centering protuberance.At their free end, they radially inwardly bend to form retained part.
At its opposite side, hub 31 have the taper of being preferably and thereby from the annular shoulder 34 of centering, it refers to 29,30 composition surface and clamping face as folder.Between annular shoulder 34 and edge 32, hub 31 is taper again; As shown in Figure 2, hub 31 downward (promptly to bottom 22) is tapered.
The thread feeder operation is as follows:
During normal running, thread feed wheel 10 is fixedlyed connected with axle 11.In position shown in Figure 2, be used for axle 11 is presented on engagement state with thread feed wheel 10 coupling arrangements that are connected 16.Under the spring effect of part 24, bottom 22 is a little to lower convexity.Folder refers to that 29,30 lean against on the annular shoulder 34 by radially inwardly pre-tensioning and with their end.Folder refers to that 29,30 flexibly are supported on the annular shoulder 34, and securely hub 31 is clamped between them simultaneously, and with respect to its centering.Since folder refer to 29,30 and other friction not shown and that do not have the folder of Reference numeral to refer between (it distributes in crown mode around periphery of hub 31) connect the connection of between thread feed wheel 10 and axle 11, setting up anti-rotation.Thread feeder 1 can be worked in a usual manner and yarn 35 is transported to knitting machine.
Under the situation that thread feed wheel 10 can be rotated with respect to axle 11, coupling arrangement 16 carries out the transition to loosening state shown in Figure 3.In order to realize this switching, from pressing to the part 23 of bottom 22 down.For example, be supported on the thread feed wheel 10 with its thumb, the operator can be pressed to part 23 with his finger.Under the spring effect of part 24, bottom 22, especially part 23, and to a little upwards sudden change of the direction of axle 11, thereby bottom 22 becomes recessedly from protruding its shape, and thereby raises up this moment.Correspondingly, all folders refer to, and thereby folder refer to that 29,30 radially outward swing away from annular shoulder 34.So, release friction connection and thread feed wheel 10 can rotate freely with respect to axle 11.Yet, because referring to the free end of 29,30 (referring to other folder), folder limits the internal diameter that is slightly smaller than annular shoulder 34 external diameters, thread feed wheel 10 still remains on the axle 11.
Will get back to engagement state once more thread feed is taken turns 10 anti-rotation ground and axle 11 couplings connection from loosening state at coupling arrangement 16, for example, the operator hits thread feed with his palm, and to take turns 10 yarn section or edge 20 just enough from below.As a result, the part 24 of bottom 22 is hit edge 32, and by this pulse, elastic bottom 22 is suddenlyd change again from spill and got back to convex.Therefore, all folders refer to that 29,30 radially inwardly swing again and are fixed on the annular shoulder 34.
Yet, to become under the situation of separation point position rather than bonding station from loosening position at thread feed wheel 10, it is caught and axially is pulled away from axle 11.As shown in Figure 3, folder refers to 29,30 outside elastic deflections and thereby leave annular shoulder 34.Thereby thread feed wheel 10 can be pulled away from axle 11 with of short duration downward wrench.Edge 20 constitutes handle H.
Replacedly, for example, thread feed wheel 10 ' shown in Figure 1 can be arranged on the axle 11.It has with thread feed takes turns 10 identical coupling arrangements 16.Thread feed wheel 10 also can install on the axle 11 once more, or more accurately, installs on the hub 31.At coupling arrangement during at loosening state, its by under shift onto on the hub 31.Folder refers to that 29,30 nose circle slides and it is latchingly in annular shoulder 34 back on the conical outer surface between edge 32 and the annular shoulder 34.In order to become engagement state, as indicated above, it is just enough to apply short impact towards the lower limb of thread feed wheel 10 to the direction of axle 11.
Fig. 4 to 6 shows the variant embodiment of thread feed wheel 10 and coupling arrangement 16 thereof.To identical Reference numeral, with reference to above stated specification.Different with previous embodiment, use coupling arrangement 16 according to Fig. 4 to 6, the torque transmission of wheel 10 connects by form fit rather than friction connection realization from axle 11 to thread feed.For this reason, for example axle 11 is provided with non-circular coupling part 36, and coupling part 36 is the hole circles that for example formed by the preface array that centers on the blind hole 38 of circumferential distribution on axle 11.In addition, coupling arrangement 16 can comprise the annular groove 37 that is arranged on the axle 11, thinks that thread feed wheel 10 limits other application position.Annular groove 37 is preferably adjacent coupling part 36 and arranges, promptly in the close vicinity of hole circle, and is preferably and is positioned at its top.
Fig. 4 shows the loosening position of coupling arrangement 16.Elastic ring 41 is pressed onto sphere 42,43 in the annular groove 37, thereby the axial location of thread feed wheel 10 shown in remaining on wherein, do not exist with spools 11 form fit to be connected.In this position, axle 11 lower ends 44 are outstanding downwards, are preferably the bottom 21 that exceeds thread feed wheel 10 a little.
Will switch at coupling arrangement 16 under the situation of engagement state, the operator for example uses two fingers with hand grip thread feed wheel 10, and is pressed on the end face of axle 11 end face of axle 11 thereby formation handle H with his thumb.As a result, thread feed wheel 10 is pressed Fig. 5 to application position of lower slider.Thereby sphere 42,43 moves in the hole of hole circle from annular groove 37.Axial displacement is very short-only several microns.
In addition, coupling arrangement can move to released state shown in Figure 6.This realizes by thread feed wheel 10 is pulled down from axle 11 in simple mode.
For the brake operating that need to be easy to, annular groove 37 and hole 38 can have the trapezoid cross section.
The embodiment that shows another modification among Fig. 7 and 8.In this embodiment, thread feed wheel 10 surrounds an inner space, and wherein the bell hub 45 of hollow is connected with unshowned axle 11.The bottom 21 of thread feed wheel 10 has at least two openings 46,47, crooked and roughly resilient supporting rod 48,49 extend through described opening 46,47, the long arm 50,51 of supporting rod 48,49 is supported in the respective notches of the slider 52 that leans against bottom 21 downsides.Slider (if desired) places on the bearing 53 that is installed on the bottom 21 and forms handle H.Supporting rod 48,49 short is positioned at bell hub 45 and thereby is positioned at the direction extension of the arm of 21 tops, bottom to the perimeter surface of hub 45.
Shown in Fig. 7 and 8,, can remove so that supporting rod 48,49 leans against on the hub 45 or from it by moving radially slider 52.Based on the spring effect of supporting rod 48,49, realize braking action.In the position according to Fig. 7, supporting rod is against the inner surface in tension of hub 45.If slider 52 radially outward moves, it at first overcomes pressure spot and supporting rod 48,49 is inwardly swung.This is corresponding to thread feed wheel 10 is transferred to loosening state from engagement state.In addition, in this position, thread feed wheel 10 can be pulled away from hub 45.Hub can have the edge of roughly inwardly setting, and supporting rod 48,49 braking ground suppress this edge.
Fig. 9 shows additional embodiments, wherein brakes sphere 54 and is arranged in axle 11 the cross drilling.Braking sphere 54 radially outward promotes by compression spring 55.Tubulose extension 56 projects upwards from the bottom 21 of thread feed wheel 10, and tubulose extension 56 has the corresponding opening that is used to brake sphere 54.Under the situation of braking sphere in opening 57, they are taken turns 10 anti-rotation ground with thread feed and are connected with axle 11.
Releasing sleeve 58 is arranged between between the annulars that extension 56 and axle 11 limit with one heart.Releasing sleeve 59 that can be axially displaced has the opening consistent with opening 57.For example, the end disc 60 that forms handle H is set and is used for mobile releasing sleeve 58.
Fig. 9 shows loosening state.Releasing sleeve 58 forces braking sphere 54 radially inside.When thereby releasing sleeve 58 moves up opening 59 when discharging braking spheres 54, sphere suddenlys change in opening 57 and thereby thread feed is coupled on spools 11 with taking turns 10 anti-rotation.
Replacedly, releasing sleeve 58 can be designed as and can take turns 10 or with respect to axle 11 rotation with respect to thread feed.The switching of coupling arrangement 16 from loosening state to engagement state realizes by rotating releasing sleeves 58 with respect to axle 11 rather than moving axially releasing sleeve 58.For this reason, end disc 60 is also manually handled.
Figure 10 shows another embodiment of the connection between thread feed wheel 10 and the axle 11.Axle 11 supporting hubs 61, hub 61 has radial contour, for example extension radially.Take turns 10 inboards at thread feed at least one flexion springs 62 is set, described flexion springs 62 can be contained in radially between the extension or have an opening of hub 61, and the opening of spring is at this radially on the extension.The further downward elongated end 63 of flexion springs 62 is as handle H, and when quilt was radially outward mobile, elongated end 63 was swung flexion springs 62 away from hub 61 downwards.Thus, thread feed wheel 10 can be thrown off from hub 61 and axle 11.
The variant embodiment of coupling arrangement 16 shows in Figure 12.Below unspecified details identical with present embodiment.
In addition, thread feed wheel 10 can be pulled away from axle 11 by it is axially pulled down.At this, extension 39 slips over O shape ring 66.
Replacedly, O shape ring 66 can remove can take away thread feed wheel 10.On the contrary, in order to install, at first thread feed wheel 10 to be shifted onto on the axle 11 and then O shape ring 66 is inserted in the groove 65.
Figure 12 to 14 shows another embodiment of coupling arrangement 16.In this embodiment, axle 11 is divided into two parts of different-diameter, and they are respectively at groove internal support O shape ring 67,68.Correspondingly, the tubular extension of stretching out from the bottom 21 of thread feed wheel 10 has two parts 69,70 at least, and described part 69,70 has different diameters and has the infundibulate changeover portion.The internal diameter that connects the part 69 of bottom 21 by funnel shaped part 69a makes it be positioned on the O shape ring 68 with good friction connection.Part 70 has bigger diameter, thereby it is positioned on the O shape ring 67 with good friction connection.The part 70a that amplifies is in abutting connection with 70.Between part 69,70 part 71 is set, its diameter encircles the shaft diameter at 67 places less than O shape.Obtain its support at the step 72 thereby the crossover position place between two parts of different-diameter on the annular shoulder 73 that so form between the part 71,70.
Axle 11 extends to bottom 21 times and at this section otch.One or more spring bow 74,75 is set, the radially outward outstanding and flexibly radially inwardly springing of spring bow 74,75 in this recess.At its relaxed state, the external diameter of spring bow 74,75 is greater than the internal diameter of part 69.
Figure 12 shows engagement state: thread feed wheel 10 is pulled in its upper position.Part 69 and 70 is in place securely on O shape ring 67,68, thereby thread feed wheel 10 is arranged on the axle 11 with rubbing connection and anti-rotation.In part 69 and/or 70, small, the carinate diameter in the zone of O shape ring 67 and/or 68 becomes big portion and can obtain axial braking action.
In order to switch to loosening state, thread feed wheel 10 is boosted, and up to part 69, the 70 O shape ring 67,68 that slips away, so O shape ring is in place on part 69a, 70a.It is corresponding to loosening state.Thread feed wheel 10 can rotate freely with respect to axle 11.The handle H that is used to handle coupling arrangement 16 forms by the edge 20 of thread feed wheel 10 or by the end faces of thread feed wheel 10 itself and axle 11 once more.
If thread feed wheel 10 will move to its released state, it is further pulled down, the axle 11 thereby the inside resilient spring bow 74,75 of its process slips away.
Having the identical of identical tubulose extension or other thread feed wheel 10 is inserted on the axle 11 with opposite order.The tubulose extension is with part 70 and at first pass through spring bow 74,75 with all other parts 71,69 thereafter, therefore reaches the engagement state according to Figure 12.So part 70,69 their tapered edges of usefulness 76,77 are in place on O shape ring 68,67, a little radially inwardly press O shape ring 68,67 and thereby will oneself be clamped on the axle 11.
In order to reach loosening state, thread feed wheel 10 at axle 11 enterprising one-step axis to boosting.
