Description
The present invention relates to have every yarn body storage and the feed unit of yarn especially for yarn, has a not Fu memory bank that is rotatably installed on the axle drive shaft, this memory bank is used to store the yarn of being made up of doff, have and distribute on week in the garden of memory bank, be roughly axially bar-shaped supporting member, its the outside can in be connected on the concentric garden of axle drive shaft in, have and distribute on week in the garden of memory bank, always be subordinated to supporting member, substantially axial bar-shaped feeding part, its outside can in be connected on axle drive shaft accentric garden in, and drive the feed motion that constitutes by radial and axial component motion with respect to fixing supporting member.
In the high speed of yarn was transported, for example in jet loom, in the yarn storage of supplying with loom and feed unit, doff during feeding was an important prerequisite of unperturbed operation every yarn on memory bank.Be to realize every yarn simply by moving feeding part with respect to axle drive shaft inclination and eccentric the installation in having the memory bank of immutable diameter by the face of cylinder.Though have only a kind of immutablely every yarn, it is suitable for disadvantageous operating condition and/or critical yarn qualities, also is a kind of compromise solution in other cases.Yet for a change this is the solution of a technical fee costliness every yarn in the axle drive shaft scope.Because but the feeding part is to be in the coupled condition of transmitting movement with axle drive shaft in this driving principle, and can move with respect to supporting member, because it is known being used to have the feeding part of annular wheel shape of swing of memory bank of the supporting member (for example be used for the weft yarn storage, feed and give and measurement mechanism) of variable-diameter, this feeding part always only axially moves forward first doff from winding side, undesirable contact area appears between the doff of storage thus, because can not carry out every yarn to doff.Though design, yet a kind of yarn storage of still not using actually, feed and give and measurement mechanism, the supporting member diameter of the memory bank in this device is adjustable, and when feeding for be distributed in the feeding part on the memory bank every yarn being provided with.
Task of the present invention is, a kind of yarn storage, feed unit are provided, and this device can simply fully adapt to different operating conditions and/or yarn qualities.
Being proposed of task is solved by feature of the present invention.Yarn storage of the present invention can change the mutual identical radial spacing of supporting member from axle drive shaft by regulating supporting member jointly with feed unit, when regulating supporting member, can change the mutual identical radial spacing of feeding part jointly from the center in eccentric garden (axle 8) by means of supporting member, the diameter in eccentric garden can change, and follows the outside of feeding part in eccentric garden.
In first solution by the associated movement of supporting member regulate quickly and accurately memory bank diameter and during without detriment to feeding every yarn, because, the feeding part has been done adjusting by means of supporting member when the adjusting of supporting member together, so just kept when feeding every yarn.The adjustment of each hope can realize rapidly that conversion time is just very short like this.Adjust even the doff on reeling and carrying out during in operation advantageously because the feeding part when the adjusting of supporting member forced adjustment be used for every relative position yarn and feeding and necessity supporting member.This can be to regulate so rapidly, for example can regulate weft length.
In second solution, for memory bank unmodified diameter, each feeding part changes with respect to the relative position of affiliated supporting member, like this, makes to adapt to each operating condition or yarn qualities every yarn and feeding.Can on the doff behind the coiling, also can when operation, adjust for certain yarn qualities every yarn.
In above-mentioned two kinds of solutions, provided the yarn storage and the feed unit that can adapt to different work condition and/or yarn qualities fully, when all having kept under each situation, obtained advantage every yarn in feeding.
By feature " each feeding part is installed in the supporting member movably; and one with axle drive shaft do not have machinery relation, preferentially be that the feeding-accessory drive of magnetic directly is placed on the feeding part " embodiment that limits proposed a kind of driving principle that deviates from common feeding part because its produces and the irrelevant feed motion of axle drive shaft.Each feeding part is installed in the supporting member movably, and one with axle drive shaft do not have machinery relation, preferentially be that the feeding-accessory drive of magnetic directly is placed on the feeding part.In having the memory bank of variable-diameter, when the feeding part does not damage feeding together with supporting member is conditioned every yarn.In having the memory bank of immutable diameter, adapt to operating condition and yarn qualities in mode simple in structure every yarn.
At the feeding accessory drive that between feeding part and supporting member, is provided with a machinery by feature, finally not only diameter adjustment is simple in the embodiment that axially is connected qualification with the axial motion control piece of axle drive shaft for this device, and regulate simple every yarn, because, its radial motion component of the feed motion of each feeding part with from axle drive shaft or the spacing of the motion control part of settling there irrelevant.Like this, can only from axle drive shaft, derive the axial motion component.Be provided with the feeding accessory drive of a machinery between feeding part and supporting member, this device finally axially is being connected with the axial motion control piece of axle drive shaft.
By feature " axle drive shaft is provided with the feeding accessory drive of a machinery; and be provided with radially adjustable attaching parts between feeding accessory drive and feeding part; attaching parts is adjusted the position in operation and had a radiai adjustment resistance, and this resistance is greater than the lamination of doff ".Draw the embodiment of another kind of particular importance.Axle drive shaft is provided with the feeding accessory drive of a machinery, and is provided with radially adjustable attaching parts between feeding accessory drive and feeding part, and attaching parts is adjusted the position in operation and had a radiai adjustment resistance, and this resistance is greater than the lamination of doff.Though can derive the radial and axial component motion of feeding part from axle drive shaft with conventional method,, can radiai adjustment feeding part, this radiai adjustment can be used for the diameter adjustment and/or every yarn and feeding adjustment.The radiai adjustment resistance of attaching parts can not be overcome by the lamination of doff, and like this, doff is raised, isolates and push ahead when feeding.

Yarn storage and feed unit F according to Fig. 1 have a fixing matrix G, and the axle drive shaft T that does not express is installed on it, and the axis of axle drive shaft T is represented with H.Be rotatably mounted memory bank K on axle drive shaft T, the method that memory bank K helps with the axle of not expressing is as ending its rotation with permanent magnetic resistance.Memory bank K is a drum-shape, and constitutes rotational symmetric storage surface, is used for storing the yarn μ that is made of doff W, particularly is used for storing the yarn of knitting of loom, and is for example interrupted, the yarn of knitting with equal length.Axle drive shaft T is supporting tubular winding mechanism I, and the winding mechanism I is reeled to continuous doff W, along the direction of arrow top of yarn network winding mechanism is pulled out from winding mechanism.Brake equipment B with the brake component B ' that can radially move around is installed on housing G, and this brake component can be braked between the doff of yarn path just as known, also can recall by doff.The storage surface of storage body K is determined by fixing bar-shaped support elements A that distributes at circumferencial direction and the bar-shaped feeding part V that is subordinated to supporting member A.Feeding part V produces a feed motion when the axle drive shaft I is rotated as telling about later on, like this, the doff W among Fig. 1 moves from left to right, and separates with predetermined spacing.
Supporting member A radially can regulate memory bank K's, and be engaged on joggle piece 1 in the flat thread 2 of adjustment disk, adjustment disk Q can rotate by transferring belt driver E to drive where necessary, changes the external diameter by the determined memory bank K of supporting member A thus.The outside of supporting member can with the concentric circle of axle H in.Each feeding part V each to all being placed in a gap in the supporting member A, but also can be placed between two supporting member A.Between supporting member A and relevant feeding part V, be provided with a radially traction power-transfer clutch S of effect, when radiai adjustment supporting member A, can make traction power-transfer clutch S and feeding part V collaborative work.
On axle drive shaft T, fixing an axle sleeve 3, the outside of axle sleeve 3 has face of cylinder Z, its axle 8 is with respect to the driving axis H α angle that tilted, thereby be eccentric (degree of eccentricity α) (Fig. 2) with driving axis H, along the rotation direction of axle drive shaft T, the dislocation between obliquity and the degree of eccentricity is 90 ° of (see figure 7)s for example.Be rotatably mounted a sleeve N coaxial with cylinder axis 8 on figure cylinder Z, feeding part V is placed on the sleeve N.Each feeding part V is connected with sleeve N with a radially adjustable attaching parts C, and attaching parts C is scheduled to the sliding slip clutch that hinders for having in Fig. 1.Feeding part V has a cylindrical neck portion 6, and it is with sliding fit and sleeve 4 engagements, and is fixing with binding ring 7.Sleeve 4 is by means of axle journal 5(axle 9) be installed in rotation in the sleeve N of Fig. 1, sleeve 4 can be limited in the diagram plane.According to Fig. 1, supporting member A has a logical first A ' of approximate axial spinning to hold feeding part V.
According to Fig. 2 and Fig. 3, the axle journal 5 of sleeve 4 is contained in the hole 10 and can swings with limitation in the hole 16 of axle 9 at sleeve N, and axle 9 is in substantially parallel relationship to cylinder axis 8.Axle journal 6 can wind by the hole 12 of sleeve 4 determined together with feeding part V, axle 11 rotations perpendicular to cylinder axis 8 because binding ring 7 is installed in the groove 13 of axle journal 6 with very little radial and axial gap, and are pressed on elastic forepressure on the wall in hole 12.
Traction power-transfer clutch S is that stopper tab 15 by block 14 on the feeding part V and supporting member A constitutes according to Fig. 1 to 3, has a predetermined gap here.
During operation, axle drive shaft T rotation, the winding mechanism I is taken yarn on the memory bank K to the form of doff W.Brake component B ' for example is positioned at position shown in Figure 1.Owing between obliquity α and degree of eccentricity e, there is dislocation, when the position when axle drive shaft T is positioned at the outside of supporting member A from its outer radial under is produced, each feeding part V at first radially outward surpasses the movement outside of supporting member A, then along axially moving right among Fig. 1, so that before the feeding part returns under the supporting member A side and is moved to the left vertically, promote, draw forward and separate doff N.All feeding part V realize successively that along hand of rotation this moves.When behind the doff W of last predetermined number, just make axle drive shaft T stall.Like this, only need yarn μ, brake component B ' is pulled back just can pull out required doff W.When the storage doff on the memory bank K is less than when a certain amount of axle drive shaft T
1Rotation again replenishes storage.
The yarn μ that is pulled out when doffing has certain length, and it can be regulated by the diameter of regulating memory bank K.Rotate adjustment disk Q, at this moment, supporting member A radially outward or radially moves inward together for this reason.At this moment, the brake equipment B on the housing E unclamps, thereby can regulate the distance between memory bank K and the brake equipment B.
Feeding part V is driven by traction power-transfer clutch S when regulating.The initial resistance of slip clutch R is overcome when regulating.Because feeding part V is at first concentric with axle drive shaft H by supporting member A when regulating, but the separation during for feeding should be determined a circle concentric with cylinder axis 8, and therefore, axle drive shaft T revolves at least and turns around, like this, feeding part V is concentric with cylinder axis 8 by means of traction power-transfer clutch S and supporting member A.Then, device F performs the operation preparation once more.Adjusting can also can be carried out between the operational period of device F by means of regulating actuating device E remote operation.The sliding resistance of slip clutch R is greater than the yarn feeding pressure of doff W, and like this, doff W just can not the radially adjustable attaching parts C of automatically regulating.Also can radially adjustable attaching parts detachable and that can fix once more be set and substitute slip clutch R with other mode.
Each vertical side at feeding part V is provided with two groups of blocks 14 and slipper 15.The radial spacing of slipper 15 (Fig. 4) equals the radial wall thickness X of two-fold degree of eccentricity e and block 14 at least.When guaranteeing the adjusting of the additional rotational motion under supporting member A and axle drive shaft thus, feeding part V presses identical relative position and supporting member A centering, because each block 14 is once braked on last slipper 15, is once braking on the slipper 15 down.Therefore, the radiai adjustment location independent of feeding and compartmentation and supporting member A.Certainly, separation is along with the diameter of supporting member A increases and increases, because the throw of lever of feeding part V has increased.
Fig. 5 a and 5b have represented the possibility of two kinds of selections, so that can regulate feeding and separation separately.But also can combine the two selection.As shown in Figure 4, after the layout of block 14 and slipper 15 is determined, just produced with the outside of the 25 feeding part V that represent with the same position between the outside of the 26 supporting member A that represent and concerned.Can change fully according to the relative height difference between the outside 26 of the outside 25 of Fig. 5 a and/or Fig. 5 b feeding part V and supporting member A, so that can change separation arbitrarily.As a kind of principle, not only memory bank K has variable diameter according to Fig. 1 and conforms with purpose, (for example, be adjusted to different separations for different yarn qualities, perhaps work as diameter and increase the time-division) every remaining unchanged, and memory bank K has immutable diameter (according to Figure 21), separates yarn and the another kind of operating condition that adapts to another kind of quality so that make.
In Fig. 7, vertical axis is represented the nominal diameter D of degree of eccentricity e or supporting member A and the feeding part V axial distance S along positive dirction and negative direction respectively.Horizontal shaft represents that axle drive shaft T changes 360 ° rotational motion.The nominal diameter D in the outside 26 of the supporting member A among horizon 28 and Fig. 4 conforms to.Rise with droop line 30 with when axle drive shaft T 0 ° with 360 ℃ between conform to because of the radial motion that exists eccentric e to produce feeding part V during rotation.When the corner of axle drive shaft was D, upper surface 25 was positioned at upper surface 26 belows-e place.In the time of 90 °, the outside 25,26 is on identical radial height, promptly at 0 o'clock.In the time of 180 °, the outside 25 above the outside 26+the e place, before it moves downward, be diameter D in the time of 270 °, finally be positioned in the time of 360 ° the outside 26 belows-the e place.In view of between obliquity α and degree of eccentricity e, there being phase place offsetting (being 90 ° for example), corresponding line 31 represents that in the time of 0 ° feeding part V(represents with downward arrow) opposite with direction of feed, that is to say, in Fig. 1, be moved to the left, until in the time of 90 °, axially return and begin motion (arrow upwards) along direction of feed (Fig. 1 to the right), move to 270 ° more always, and then return.Because upside 25 (in 0 scope) between 90 ° to 270 ° is positioned at the top of upside 26, so the winding thread W of yarn drives through a maximum range and separates.
If the diameter D among Fig. 5 a or the 5b increases to D by regulating block 14 and/or slipper 15
1, so surperficial 25(curve 30) and in short scope P, surpassed surperficial 26(diameter D), make the shorter scope P of axial motion diametal curve 31 pass to doff W.Feeding and diminish every yarn.The circle diameter that this process also can be described as hypothesis supporting member A changes.If supposition changes feeding part circle diameter, also can reach identical effect.
In Fig. 5 a and 5b, for each feeding part V or each supporting member A are provided with separately regulating mechanism J.Also it is contemplated that for all feeding parts or all supporting members are provided with a common regulating mechanism J, so that can concentrate adjusting.Regulating mechanism J available adjustment disk with flat thread for example shown in Figure 1 is handled.
According to the memory bank K among Fig. 1 with variable-diameter, can utilize the common control apparatus of supporting member to change feeding and every yarn, for example, the adjustment disk Q among Fig. 1 has actuating device C in particularly advantageous mode, be stepper motor for example.For this situation, the spacing between the slipper 15 among Fig. 6 a is selected the big surplus Y of radial wall thickness X than the additional block 14 of two degree of eccentricity e.Surplus Y conforms to degree of eccentricity e substantially and conforms with purpose.
In this structure,, at first supporting member A is adjusted to diameter D along arrow 23 directions in order to reach the maximum adjusting that has that Fig. 7 (curve 28,30) conforms to every yarn
2, diameter D
2Greater than nominal diameter D.Suppose that eccentric e is positioned at axle drive shaft T90 ° position of rotation, so, the feeding part V among Fig. 6 a is pulled above block 14.Then, axle drive shaft changes full one at least and changes (Fig. 6 b), and at this moment, feeding part V drops to distance 15 1 eccentric e of slipper down.Owing to exist surplus Y in this adjusting, can not produce, because the 25 not free surfaces 26 of crossing, surface every yarn.Therefore, it is last according to Figure 66 supporting member A being positioned at diameter D along arrow 24 directions downward modulation surplus Y until the outside 26.So just produced and had maximum maximum feeding, because 0 scope that travel forward (curve 31 is between 90 ° to 270 °) have crossed curve 30 effectively every yarn.
In order to reduce every yarn, for example because different yarn qualities, or since the increase of diameter in order to offset the increase of yarn, supporting member A, for example radially outward regulate supporting member A along arrow 27 directions (Fig. 6 d), be positioned at diameter D until the outside 26 by means of the adjustment disk Q among Fig. 1
1 Till.Curve movement 30,31 is just folded mutually in scope P.Just can directly change by means of operation supporting member A or its control apparatus in this way every yarn and feeding.Can regulate jointly for all feeding parts, also can when operation, regulate, for example by rotating driving device E.In view of desirable weft length should keep diameter D, therefore, for reduce among Fig. 6 c every yarn, before supporting member A modulates diameter D once more, at first must feeding part V together with last slipper 15 once more downwards the fine setting.Enough electric controllers of energy and actuating device E be remote control adjustment simply, and very high precision is arranged.
Common regulate supporting member and feeding part and in having the memory bank of variable-diameter, change every yarn and feeding or to have the prerequisite that changes every yarn and feeding in the memory bank of constant diameter be to have radially adjustable attaching parts C between feeding part V and axle drive shaft T.
Following embodiment represents the dissimilar of other part.
According to the memory bank K that yarn storage shown in Figure 8 and feed unit F have variable-diameter, each feeding part V is divided into a top 32 and a bottom 33, and top 32 can move axially on bottom 33.Spring members 39 guarantees that feeding part V is near memory bank K.Each top 32 and bottom 33 are connected with separately sleeve N through radially adjustable, a telescopic and flexible locking attaching parts 34, like this, just can transmit the axial motion component of sleeve N.Each sleeve N is rotatably installed on the Z of the face of cylinder, and face of cylinder Z and axle drive shaft tilt to install, but not eccentric.Between the obliquity of two sleeve N, be provided with hand of rotation dislocation along axle drive shaft T.Locking attaching parts 34 is made of the pipe 35 and 36 that is installed on each upper and lower 32,33, is engaged with the locking piece 38 of ball-shaped counterlath 37 in pipe 35 and 36.Bottom 33 is installed on the inclined-plane 40 of the static supporting member A that improves vertically movably together with inclined-plane 41.
In the axle drive shaft T that is made of hollow shaft adjusting shaft 42 is installed movably, adjusting shaft 42 is supporting adjusting axle journal 43, and axle journal 43 is engaged on the inboard of the sleeve 44a that determines face of cylinder Z along tilt adjustment background 44.Can drive adjusting shaft 42 with the adjusting actuating device 46 that is installed in the outside moves back and forth along four-headed arrow 45.Can change two dislocation (adjusting) between the Z of the face of cylinder thus arbitrarily every yarn, in addition opposite, and this sampling device F can rotate along two hand of rotation in an advantageous manner.Owing to exist dislocation to make bottom 33 improve top 32, and when improving motion, the axial motion along direction of feed has been realized on top 32 through the surface of supporting member A.When bottom 33 descended on inclined-plane 40, when the surface on top 32 returned under the surface of supporting member A, top 32 was just returned vertically.When changing the diameter of supporting member A, as with Fig. 1 explanation, also regulated feeding part V, at this moment, remained unchanged every yarn and feeding.
In the embodiment of Fig. 9, do not have not expression of two sleeve N(as shown in Figure 8) and locking attaching parts 34, carry doff thus and, between bottom 33 and top 32, be provided with two eccentric driving devices 47 that are bearing on the supporting member A every yarn.Eccentric driving device 47 is through two pipe links, and promptly top 32 forces to be connected with bottom 33 mutually, according to the locomotive method of attachment, has so just produced the circulating motion at 32 no dead points, top, and the direction of feed motion is being passed on the surface 25 on top 32 forward and downwards when promoting.Can change every yarn by the dislocation between the obliquity of regulating two sleeves as shown in Figure 8.
In the embodiment of Figure 10, be provided with two sleeve N as shown in Figure 8 equally, so that moved vertically in bottom 33 and top 32.33 usefulness its pipe 35 in bottom is integral with control stalk 49, and control stalk 49 always is hinged on axle 51 rocking bars that can swing 50 in supporting member A53 place.Another arm of rocking bar 50 meshes with rotation-sliding guide piece 52 in the axial spinning passage on top 32, when pipe 36 produces axial motions, finally can pass to top 32 to lifting and descending motion like this.
Figure 11 has represented a similar embodiment.33 usefulness its pipe 35 in bottom links to each other with bar 49, and bar 49 is hinged on the rocking bar 50 at its two ends, 53 places.Rocking bar 50 can swingingly be installed on the supporting member A around axle 51, and its another arm 54 is connected with top 32.But arm 54 is elastic bendings.
Two sleeve N have also been used among the embodiment in Figure 12 a and 12b, so that axial adjustment top 32 and bottom 33.Bottom 33 moves axially in the support 55 of supporting member A, and has an inclined-plane 40 that promotes vertically, and the relative inclined-plane 41 on top 32 is installed on inclined-plane 40.Needle roller can be installed roll 57 in order to reduce friction and abrasion.
Embodiment among Figure 13 has a traction connector S, and its structure is that clamp dog 15 is axle journal for surplus hole, block 14.Feeding part V is an one, and oriented inner process, fork-shaped extension 60, magnetic devices 61 is installed on extension 60.A sleeve N who has on axle drive shaft is arranged between magnetic devices 61, the dish 58 concentric with axle H, dish 58 has magnet 59.Magnet 59 interlaced arrangements also have different polarity.When dish 58 rotation, produce alternation axially and radial magnetic force, in the stroke of the traction power-transfer clutch of this magnetic force in supporting member to the feed motion generation effect of feeding part.
Radially another driving principle of the feeding part that can regulate with supporting member A is provided by Figure 14.But feeding part V is installed on the transverse axis 62 of sleeve N with the arm 64 of its axial elastic bending, and is in radially adjustable slide plate 63.Sleeve N is installed in rotation on the Z of the face of cylinder, and face of cylinder Z belongs to axle sleeve 65, and with axle drive shaft T off-centre is arranged.From sleeve N the radial motion component is passed to feeding part V.Another sleeve N is installed in rotation on the axle sleeve 66, and axle sleeve 66 has been determined the face of cylinder Z with axle drive shaft T inclination installation.Through a draw bar 67 the axial motion component is passed to feeding part V with the radially-directed groove 68 that is used for attaching parts 69, and folded mutually with the radial motion component.Degree of eccentricity and the offsetting of the phase place between the obliquity by regulating sleeve N can change every yarn and feeding, or the conversion hand of rotation.
In the embodiment of Figure 15, work be axial traction bar 67 ', draw bar 67 ' just act on vertically on the feeding part V, and be installed in spring 73 in the supporting member A along acting in opposition by the bevelled sleeve.Feeding part V is installed in the supporting member movably, and for example often guiding piece 71 is installed in the corresponding groove 72, and is radially driven by accentric sleeve N.Radially adjustable attaching parts C is a slide block 70.The arm 64 of feeding part V ' in radially adjustable attaching parts C, axially can misplace.In two embodiment (Figure 14 and 15), radially adjustable attaching parts e fixes when operation, and just for a change the diameter of memory bank is only adjustable.
In the embodiment of Figure 16, feeding part V links to each other with inner component 74 with arm 64 its axially spaced-apart, elastic bending, and inner component 74 so is installed on the regulating part 76 of sleeve N radially adjustablely, promptly sells 75 and is contained in the tipper 77.By moving and axle drive shaft accentric sleeve N, move radially feeding part V so that regulate.This attaching parts is fixed when operation.Sleeve N has an extension 78, and this extension 78 is done the axial motion transmission with regulating part 79 and is connected, and like this, but regulating part 79 passes through just axial adjustment of setting nut 80.The axial motion component is with shown in Figure 14 the same as draw bar 67 transmission, and draw bar 67 is installed on the sleeve that tilts to install with axle drive shaft.
Embodiment according to Figure 17 has two isolated sleeve N that are installed in rotation on the eccentric cylinder, on the face of cylinder of the axle drive shaft T that is rotatably tilting to install between these two sleeves the sleeve that another is not expressed is installed.Its downside of feeding part V has two pipes 83, is meshing the bar 82 that is installed on the sleeve N in the pipe 83, and bar 82 is always supporting a binding ring 7(slip clutch R as the embodiment of Fig. 2 and 3 as showing).In intermediate pipe 81, meshing bar 37 as the intermediate sleeve of axial actuator.Bar 82 preferentially is to be installed on the sleeve N through ball pivot through cutting with scissors 84.In addition, feeding part V moves (traction power-transfer clutch S) in the support 85 of supporting member A.
Embodiment according to Figure 18 has used center of pressure piston 86, this piston 86 and the pipe 83 interior engagements that constitute the cylinder body pipe, and be installed on the bar 82.Pipe 83 usefulness pistons 86 have limited pressure chamber 87, and pressure chamber 87 is full of in certain superpressure and the pressure medium under the low pressure.In operation, do radial motion conversion rapidly and since in the pressure chamber 87 abrim pressure stoped moving of piston 86, so just transmitted the radial motion component.In order to turn to (quite slowly realize) piston 86 mobile in pipe 83 is possible, for example allows slowly to change the interior degree of filling of pressure chamber 87 by flow regulating valve 88.The axial motion component produces as two embodiment faces of cylinder through intermediate pipe 81 and tiltably-mounted as stating in front.The radial motion component is only derived by eccentric sleeve.
Be provided with an electromagnetic actuator device according to Figure 19 for the feed motion of feeding part V.Feeding part V is made of the plate 89 that can move radially on supporting member, and magnet 90 and 91 acts on the plate 89, and through electric power conductor 92 usefulness beat ground controlling magnets 90 and 91, like this, magnet produces radial motion and another magnet produces axial motion on feeding part V.Traction power-transfer clutch S between supporting member A and feeding part V has limited stroke and guiding feeding part V.Magnetic force will be created between supporting member A and the feeding part V, and like this, feeding part V is just irrelevant with axle drive shaft.Feeding that keep identical is controlled with the diameter of each supporting member is irrelevant.Can change every yarn and feeding or change the hand of rotation of this device by modulation magnet 90,91 magnetic pumpings.
The feeding part V of Figure 20 is provided with for yarn storage and feed unit among the Fig. 1 with variable memory bank diameter.The outside 25 of feeding part V is located on vertical plate 93, and plate 93 finally radially is installed on the feeding part V movably through guiding and limited part 94, and by spring installation 95 stand under load radially outward.Under the lamination of doff W, spring installation 95 remains on radially export-oriented end position to plate 93 usually.When diameter increases, stoped longitude circle around after the brute force of doff stretch because spring installation 95 is toward retraction, and when new doff had only very little lamination, plate 93 just was in the radial outer end end position once more.Prevented the broken yarn that may occur with this mode.
Figure 21 has represented to have immutable diameter D
FYarn storage and the memory bank K of feed unit F '.Feeding part V is fixed on the sleeve N jointly.Sleeve N is rotatably installed on the Z of the face of cylinder, and face of cylinder Z and axle drive shaft H tilt to install and exist eccentric.Each sleeve N has radially outer, as to constitute guide 96 a cylindrical extension with hole 99, inserts the accessory 97 of the circular extension of feeding part V as guide in the hole 99.Exist the inlet that leads to regulating mechanism J in the groove 98 that in the outside 25 of feeding part V, is provided with.Regulating mechanism J is made up of adjustment disk 105, and adjustment disk 105 has its 106 screw-in in the tapped bore 101 of sleeve N.An outer block that screws in 104 radially is fixed on feeding part V to governing screw 105 with the block 103 that is positioned at the below.Axle 106 passes the hole 102 of feeding part.Wedge 100 stops feeding part V to produce the undesired rotation motion around screw shaft where necessary, and limits the up stroke and the down stroke of adjusting distance possible between (not expressing) guide 96 and 97.In this way radially adjustable attaching parts C or slip clutch R are regulated, poor with the static relative height that changes between the outside 25 and 26.Make feeding part V radially produce inside or outside motion by rotation adjusting screw(rod) 105, thereby change the scope that is used for feeding, in this scope, surface 25 is crossed surperficial 26(and is asked for an interview Fig. 7).Be provided with a regulating mechanism J according to Figure 21 for each feeding part, this regulating mechanism makes several feeding parts not play the advantage of feeding effect.But one that the adjustment disk Q that is similar among Fig. 1 also can be set can be to the common regulating mechanism of regulating of all feeding part V.
