A kind of method and apparatus with reel for yarn coiled cross-roll, wherein yarn is wound up on the bobbin with constant speed by the guiding of fro guiding-yarn device.In order to prevent in package, to form sliver (folded circle), shorten the stroke of fro guiding-yarn device, change the reciprocating frequence of thread-carrier periodically, keep the thread-carrier reciprocating speed constant simultaneously.During the reciprocating frequence of thread-carrier is constant, also undertaken anti-stacked by the reciprocating speed that changes thread-carrier.With the length that stop motion mechanism control thread-carrier moves back and forth, stop motion mechanism can inside and inside and outside motion, changes to realize required stroke.The specific embodiment of several fro guiding-yarn devices is disclosed simultaneously.
Description
The present invention is generally relevant with device with a kind of coiling method of yarn, and in order to produce a kind of cross-roll of pattern, in this package, thread layers is reeled with at least 2 ° the angle of gathering.In more detail, when the present invention relates to reel textile yarn, prevent to form the anti-stacked method and apparatus of sliver (folded circle).
US Patent NO.4,296,889 disclosed a kind of anti-stacked methods are to become cross-roll with a kind of known " fluctuation method " device coiling textile yarn.This device constantly changes the reciprocating frequence of thread-carrier by the crank motion of acceleration and deceleration thread-carrier.The defective of this device be winding speed be package circumferential velocity and yarn reciprocating speed geometry and, this speed changes, and causes the bad variation of yarn tension.
From US Patent NO.3, during 730,448 also known production cross winding yarn bobbins, shorten stroke (stroke change) periodically.According to the method for this patent, a kind of addition speed is superimposed upon the crank motion driving device forward or backwards, and promptly on groove drum, this groove drum is the identical trip distance of crank motion always.As a result, if the reciprocating travel change, the fro guiding-yarn device is just with identical reciprocating frequence, but the reciprocating speed to change, and a/s trip distance is reciprocating.And the method for this cyclical swing stroke also is used to produce straight tubular and biconial package.According to this method, the crank motion velocity variations causes that winding speed changes, and causes the variation of unfavorable yarn tension in addition.
Change for fear of this unwelcome yarn tension, US Patent NO.4, a kind of method of 325,517 suggestions, wherein anti-superimposition stroke change is carried out simultaneously.As a result, compensated variation widely for the variation that becomes the reciprocating speed that stroke takes into the anti-stacked reciprocating speed of taking.This a kind of method in back has obtained further developing in 659,027 disclosed methods at US Patent NO.4, can produce straight tube package uniformly, makes yarn do not had any problem by unwinding in the speed that is higher than 1000 meters/minute.
Compare with the wind2 of above-mentioned prior art, method and apparatus of the present invention relates to a kind of method for winding, wherein in anti-superimposition change stroke, do not change the reciprocating speed of thread-carrier, and in the method for above-mentioned prior art, anti-superimposition change stroke is interrelated, therefore in the present invention need be in the synchronism that needs very big expense to realize aspect machinery and the electronics.
Or rather, method and apparatus of the present invention comprises that the speed with a kind of substantial constant supports reel for yarn on the bobbin (package) around core shape, and yarn is reciprocal on bobbin with certain reciprocating speed, this speed is about 3.5% of bobbin circumferential velocity at least, so that gather angle coiling thread layers with about 2 °.And the present invention also comprises a kind of method, promptly when keeping the constant yarn guiding speed of fro guiding-yarn device, by shortening its stroke, changes the reciprocating frequence of thread-carrier periodically.This on-cycle advantage that periodically changes stroke is: can not form folded circle at the constant yarn tension last volume winding yarns of the best.
According to the present invention, because perhaps electromechanical engineering and textile technology method were necessary to inject the resting period that stroke does not shorten between each cycle of the stroke change of shortening trip distance.In these resting periods, there is the possibility that forms folded circle.Therefore, in these resting periods, it is anti-stacked that suggestion changes reciprocating speed.
Reciprocating frequence for the Iterim Change thread-carrier, when keeping constant reciprocating speed, shorten stroke, this device preferred embodiment comprises: one packagedly has a fro guiding-yarn device, along the straight line stroke track between two sections inverted running belts of belt conveyor can be reciprocating slide plate, be arranged on the stop motion mechanism at the end points place of slide plate stroke, for making slide plate alternately be connected the fixing device of equipping with two sections inverted running belt-drivings of belt conveyor, in order to adjust the trip distance of fro guiding-yarn device, stop motion mechanism is installed it can inwardly and outwards be moved mutually.
In the preferred embodiment of yarn reciprocating apparatus, the fixing device that is contained on the slide plate can move between first and second positions, so that, for fixing device is moved, equipped control setup in addition between the primary importance and the second place with the belt engages of two sections inverted runnings.Control setup comprises a pair of stop motion mechanism and the cam mechanism that is contained on the slide plate that is contained near stroke track two ends.Rotate between first orientation and second orientation by the stop motion mechanism cam mechanism.Cam mechanism and fixing device are connected to each other, and when cam mechanism rotates between first orientation and second orientation, fixing device are equally also moved between the primary importance and the second place.And equipped the spring offset assembly, and make cam mechanism towards first orientation and second orientation deflection, when cam mechanism forwards the centre of first orientation and second orientation to, spring is in the dead center position of maximum, force.
Stated purposes more of the present invention and advantage, other situation connection with figures is introduced, wherein:

Figure 11 is the simplified side view that has the up-coiler of a plurality of winding stations side by side according to of the present invention.
Figure 12 is the simplified side view according to another embodiment of the up-coiler with a plurality of winding stations of the present invention.
More specifically with reference to the accompanying drawings, Figure 11 illustrates the wind2 with a plurality of winding stations side by side, and with substantially invariable speed delivered yarn 8, yarn 8 quilts are around being supported on the bobbin 57 by the core shape of axle with axle bearing on each winding station.Bobbin 57 is rotated with constant circumferential velocity by driven roller 58 and motor 59 transmissions.When reeling, utilize thread-carrier 7 that yarn is moved back and forth along bobbin, thread-carrier is below with the part of the reciprocating apparatus described in detail.In this class was reeled, the yarn reciprocating speed was about 3.5% of yarn speed (equaling the circumferential velocity of bobbin) at least, preferably is about 5.7% of yarn speed at least.These percentums are represented yarn and perpendicular to the tangent of corresponding 2 ° and the 5 ° angles of cut between the tangent line of the yarn of bobbin shaft.
Or rather, as shown in Figure 1, the rotation type of belt drive of drive belt 1 is: belt 1 extends between two belt pulleys 2 and 3, and on belt pulley, conventional belt transmission 55 makes its direction running along arrow 4 indications.One slide-plate 5 slides along the line slideway 6 that extends between two sections heterodromous belts and separate.Fro guiding-yarn device 7 is contained on the slide plate 5 yarn 8 is led, and makes yarn along advancing perpendicular to page, intersects and supports on the bobbin around core shape, and Fig. 1 does not represent.
Be contained in the belt clamping apparatus on the slide block 5, between two sections belts of belt 1.This fixing device comprises a fixed chuck 9.L, and the outside of the belt of the right-to-left motion below chuck 9.L is close among Fig. 1 links to each other with slide plate 5.Curved spring is that bow type spring 11.L is fixed on the bearing 10.L of its upper end in one, and bearing 10.L is contained on the slide plate 5, near the one section belt that moves from left to right.A movable chuck 12.L is contained in the lower end of bow type spring 11.L, and when bow type spring was in free state shown in Figure 1, movable chuck 12.L and belt 1 were thrown off.Corresponding part 9.R～12.R and slide plate 5 move right together, and these parts are opposite the setting for corresponding part 9.L～12.L along side direction.Therefore, fixed chuck 9.R is fixed on the slide plate 5, is positioned at the outside of one section belt top, that move right equally.Movable chuck 12.R is contained in the free end of bow type spring 11.R, move right, above the inboard of one section belt.
A central rotating shaft 13 is contained on the slide plate 5, is positioned at the center of slide plate driver element.The eccentric guide cam 14 of plate-like is hinged in the rotating shaft 13, and eccentric disk (cam) 14 has the smaller profile diameter in the angle of about 180 ° of circumference, and has than major diameter at remaining about 180 °.Eccentric disk carries out the transition to major diameter and forms cam face from minor diameter, and it contacts with bow type spring, in the following manner, makes bow type spring 11.L and 11.R be tending towards stretching.
A trundle 15 is fixed on the eccentric disk 14, and is protruding by the elliptical aperture 16 on another rotating disk 17, rotating disk 17 is installed it is rotated around central rotating shaft 13, plays the index plate effect.Extension spring 18 1 ends are fixed on the spring shaft 19, and spring shaft 19 is contained on the slide plate 5, and the other end of extension spring 18 is contained on the trundle 15.Spring shaft 19 from the slide plate 5, the inclined to one side untie-sell 15 on the eccentric disk 14 is positioned at the right side of central rotating shaft 13.Therefore as shown in Figure 3 when eccentric disk 14 when position shown in Figure 1 forwards position shown in Figure 4 to, spring 18 is crossed its dead center position.
One end of extension spring 20 links to each other with spring shaft 19 on being installed in slide plate 5, the other end be contained in the spring shaft of radially controlling on the protruding handle 22 21 and be connected.Protruding handle 22 and index plate 17 are one.Spring shaft 21 is positioned at outside the center of turn of rotating shaft 13, and its place diameter is greater than the fastening point place diameter of spring 18 on eccentric disk 14.Like this, as shown in Figure 3 and Figure 4, when index plate 17 rotated, spring 20 was crossed its dead center position.
For the outer end that makes the protruding misfortune 22 of control contacts with 23.L with stop motion mechanism 23.R, the protruding handle of control is contained in the appropriate location when slide plate 5 arrives the right side with the left side end position.Retainer 23.L and 23.R are contained on corresponding threaded shaft 26.L and the 26.R, and threaded shaft is by separately stepper motor 27.L and 27.R transmission.The rotation of stepper motor is by process controller 28 controls, so that can two-wayly rotate.With illustrative purposes, as shown in Figure 1, process controller also is connected effectively with belt transmission 55 for below.Roller 24.L and 24.R are contained on the slide plate 5, as retainer and the guide of movable chuck 12.L and 12.R.The rotation of controlling protruding handle 22 is subjected to the restriction of cooresponding retainer 25.L and 25.R, and retainer 25.L and 25.R lay respectively at two opposite ends on sliding top.
As shown in Figure 1, crank motion slide plate 5 is moving right, because by fixed chuck 9.R and movable chuck 12.R, one section belt that one section belt on it and top promptly moves right links to each other.Slide plate 5 moves right up to the protruding handle 22 of control always meets right side stop motion mechanism 23.R.As shown in Figure 2, when control protruding handle 22 and right side stop motion mechanism 23.R collided, owing to the invalid relative motion that trundle 15 moves and causes along the elliptical aperture in the index plate 17 16, eccentric disk 14 And did not sway at once.Shown in Figure 2, along with index plate 17 moves to dead center position, extension spring 20 is elongated to the top at rotating shaft 13 centers, but the position of eccentric disk 14 does not change basically yet, so eccentric disk 14 continues to push down bow type spring 11.R with it than the cam face of long radius, thereby movable chuck 12.R and fixed chuck 9.R still clamp the both sides of belt 1.
Along with slide plate 5 continues to move right, slotted eye 16 has arrived its most end in the index plate 17, makes trundle 15 on the eccentric disk 14 with anticlockwise motion.As shown in Figure 3, when index plate is crossed the dead point, the power of extension spring 20 promptly works.At this moment, key is: the rotating shaft 21 of index plate 17 upper springs 20 is more farther from the common rotating shaft 19 of two springs than trundle 15 on the eccentric disk 14, and trundle 15 also is the hinge-point of spring 18 simultaneously.Therefore spring 20 is applied to the rightabout power that the pulling force on index plate 17 and eccentric disk 14 fabricate blocks applies above spring 18.This effect makes the protruding handle 22 of control forward left position shown in Figure 4 to anticlockwise direction.
When moving to Fig. 4 position, the major diameter of eccentric disk 14 contacts with left side bow type spring 11.L, and spring is opened.So, now to the downside belt of left movement by fixed chuck 9.L and movable chuck 12.L friction grip, make slide plate 5 to left movement.When the protruding handle 22 of control contacts with left side stop motion mechanism 23.L, protruding handle 22 rotates in a clockwise direction, and one section belt-driving on slide plate 5 and top is connected, and thread-carrier 7 is moved right as Fig. 1.
Stepper motor 27.L and 27.R transmission simultaneously or independent drive individually or preferably synchronously move stop motion mechanism 23.L and 23.R to the direction at the center of thread-carrier 7 strokes.In order to produce required stroke change, the preset program control of this mobile available programs control setup 28.Control principle described herein is by US Patent NO.4,659,027 and the German patent applications 3602853 announced has not yet introduced, in these applications the change stroke principle of explanation make the production shape accurately the cylindrical shape cross-roll become possibility.
On diagram of curves shown in Figure 5, marked the longest reciprocating travel H of thread-carrier 7 in ordinate or vertical direction, with dashed lines and h have represented the shortest reciprocating travel of thread-carrier.The horizontal direction abscissa is represented time shaft.Solid line diagram thread-carrier is in the crank motion distance of whole stroke H rise time axle.Dotted line is depicted as thread-carrier in the crank motion distance of shortest route h along time shaft.A crank motion is called the doublestroke of thread-carrier.Duplicate rows number of passes in unit time is called doublestroke speed, or is called reciprocating frequence as the application.Crank motion duration T or t are called the doublestroke time each time.As shown in Figure 5, the doublestroke time is depended on the reciprocating travel length of thread-carrier, therefore, the reciprocating frequence 1/T of long travel H is less than the reciprocating frequence 1/t of short reciprocating travel h, and at the reciprocating speed (dH)/(dT) of long travel H and equal in past the speed (dh)/(dt) of short travel h.Like this, change the variation that does not cause reciprocating speed according to stroke according to the present invention.Winding speed and yarn tension keep constant when therefore batching.
On the other hand, reciprocating frequence (doublestroke speed) is a key factor that forms folded circle.The ratio if reel, be winding speed to the ratio of doublestroke speed be integer, just will produce the folded circle of one-level, if reel than reeling when departing from a mark big, that the integer denominator is arranged (especially 1/2,1/3,1/4), will form rudimentary folded circle with the integer of its back.Change stroke periodically according to the present invention, can consider following several anti-stacked method: (1) shortens reciprocating travel consistently, avoid the coiling ratio of serious folded circle phenomenon, or (2) are as a kind of additional system of selection, regularly or aperiodically change the ratio of reeling in a kind of fluctuation mode, can eliminate serious folded circle phenomenon immediately, the coiling that makes folded circle tendency prevents folded circle phenomenon than as just temporary transient transition.
Figure below is represented crank motion to the slope of time among Fig. 6, and last figure expression reciprocating speed is to the slope of time, and these two diagram of curves are horizontal axis of abscissa with the time all.The ordinate of figure below is represented cooresponding stroke H and h.Should notice that the slope of a curve that aduncate curve is promptly drawn represents reciprocating speed, the variation of the reciprocating speed that draws in from the graph fails to show in figure below, and this is because this variable quantity is quite little, also because some deviation of figure below curve.
Shown in diagram of curves following among Fig. 6, the shortening of stroke occurs in tK in the time, and this can be called the stroke variable cycle.In these times, trip distance shortens gradually up to shortest length h, and then, trip distance increases gradually gets back to long travel H.The interior stroke of the cycle tR that has a rest in week does not shorten.
Shown in last figure among Fig. 6, reciprocating speed V(dimension is a meter per second) in the stroke variable cycle that stroke shortens, keep constant.Reciprocating speed fluctuates in resting period tR, and reciprocating speed is done continuously periodically or be acyclic but be to change repeatedly at least in this cycle, and variation is no more than 10% of aviation value.
This wave method in order to anti-stacked purpose is familiar with by people, can be realized by the package driving device 59 of process controller shown in Figure 1 28 controls.Wave the bad in matchmaker surname Buddhist nunnery location at the humorous time humorous root of Dahurian angelica tomb that begs for of contribute to a feast phlegm scheme Wei
In the embodiment of Fig. 7, the belt of rotation is tensioned between two belt pulleys 2,3, rotates with the direction of arrow 4.As shown in figure 11, belt also can extend to several winding positions, and slide plate 105 links to each other with each winding station.Each slide plate 105 slides along line slideway 106 between two sections parallel belts, and each slide plate has a fro guiding-yarn device 107, and 107 pairs of yarns of thread-carrier, 8 guiding make yarn along advancing perpendicular to the direction of drawing.
Belt clamping apparatus is contained on two sections slide plates 105 between the belt, it comprises that is contained in the one section belt outside that is positioned at left motion on the slide plate 105, and the first chuck 109.L of adjacent this belt and be contained on the slide plate 105, the adjacent second chuck 109.R that moves right one section belt outside.The transmission device of fixing device is installed on two sections slide plates between the belt, and this mechanism comprises that one clamps erecting frame 126 and spring 120.L, 120.R.Clamping erecting frame 126 plane, that have the I-beam section cross-sectional plane can slide along orbit.Deflector roll 124.L and 124.R limit the track that clamps erecting frame 126, and this track extends in the direction of laterally promptly rotating perpendicular to belt, so crosspiece moves between deflector roll 124.L and 124.R in the middle of clamping erecting frame 126.Two end opposite of erecting frame constitute movable chuck 112.L and 112.R, and when clamping erecting frame 126 crank motions, chuck 112.L and 112.R can move to clamped position respectively.At clamped position, corresponding one section belt clamps by movable chuck 112.L and fixed chuck 109.L or by movable chuck 112.R and 109.R.Fig. 7 represents the clamped condition under the chuck 112.R effect.Stage clip 120.L and 120.R make clamping erecting frame 126 chuck 112.L and 112.R be displaced to each cooresponding clamped position.One end of each stage clip is contained on the slide plate 105 by carriage 110.L and 110.R respectively.Spring bracket is installed exactly along the center line 134 of slide plate 105, and it is also on the center line between two clamped positions that clamp erecting frame 126.The other end of each stage clip is fixed on and clamps on the middle crosspiece of erecting frame, promptly exactly on the center line between two chuck 112.L and the 112.R.Distance between chuck 112.L and the 112.R is less than the distance between two sections belts.Because the power size that spring 120.L and 120.R produce is identical, direction is opposite, make to clamp erecting frame and deflector roll 124.L and 124.R are not applied any effective force, so there is not friction when being directed in erecting frame.
Guide is the commutation element of the clamping driving apparatus of roller 122 types, is installed in the center of the middle clamping erecting frame 126 of two chuck 112.L and 112.R.The axis normal of roller 122 is in clamping the middle crosspiece of erecting frame.Retainer 123.L and 123.R are contained in the two ends of reciprocating travel, retainer can maintain static, but they also can be installed on support 127.L and the 127.R, support can be that the direction of crank motion stroke is moved along the direction of arrow indication, so, support 127.L also can link to each other with threaded shaft 129 with 127.R, and Fig. 7 does not represent the transmission of threaded shaft.Retainer 123.L and 123.R are designed to each spigot surface that a roller 122 is arranged, and this spigot surface has the shape of cam, and single face opens towards roller 122.The A/F of this cam is corresponding with the distance that clamps erecting frame 126 motions between two clamped positions, along with roller 122 diameters increase and increase.The cam shedding side is consistent with the tangent line of roller 122 orbits.In addition, the cam-shaped retainer can make roller avoid impact shock, motion steadily.
The running condition of Fig. 7 embodiment is described now.As shown, chuck 109.R and movable chuck 112.R are clamped on the one section belt that moves right because reciprocal slide plate 105 is fixed, and slide plate 105 moves right.Slide plate moves right up to commutation roller 122 always and moves in the retainer 123.R of right side.Because cam-shaped retainer open side is consistent with the roller tangent line, impact shock has been avoided in this motion.Roller 122 slides along the cammed surfaces of retainer 123.R then.The result cause erecting frame 126 upwards, i.e. upward one section belt movement.This motion lasts till that roller arrives at the deepest point of cam-shaped side, thereby slide plate and belt are thrown off fully.In addition, slide plate has arrived the most end of reciprocating travel at that time.Because roller 122 continues to slide in retainer 123.R, a rightabout acceleration/accel acts on slide plate 105.Simultaneously, clamp the dead point that erecting frame 126 is crossed stage clip 120.L, 120.R, i.e. line of centers between two of fixing device clamped positions.Therefore stage clip is pressed onto another clamped position clamping erecting frame 126, and in this position, movable chuck 112.L and fixed chuck 109.L clamp one section belt.Top then one section belt makes slide plate 105 to the left end of left movement up to reverse stroke, once more commutation.
Support 127.L and 127.R are contained on the threaded shaft 129, and guide rail 128 guarantees that support does not change.Threaded shaft can be used as the function of roll diameter or time, or with said method in preset program as one man by manual control.Kong Zhi result is the position that changes retainer 123.L and 123.R like this, thereby changes the length of reciprocating travel.
Fig. 8 has represented an embodiment, wherein, is to use fork 223.L and 223.R as the retainer of retainer with replacement cam-shaped side, and each fork is contained on the mounting seat of stroke turning point.By swinging cooresponding fork 223.L or 223.R, erecting frame 226 is moved between its two clamped position.For this reason, each fork has a pin 260 at its free end, and erecting frame 226 has two guide frame 222.L and 222.R, the pin fit of each guide frame and its cooresponding fork.Guide frame is fixed on the erecting frame 226, each all have one near and be parallel to the side of longitudinal centerline 234 between two sections belts haply.Fork 223.R, 223.L wind perpendicular to the rotating shaft 261 of center line 234 and rotate.Pin 260 is contained in below the fork, and near its free end, in order to make fork as shown in Figure 8 with the anticlockwise direction swing so that and the despot shorten the refined careless 63 that makes a noise of the humiliation trip of disputing and mesh, spring 262 has been installed.
As shown in Figure 8, slide plate 205 is with the direction of arrow 4 indications, to left movement, therefore vertical side of guide frame 222.L will be to pin 260 motions of fork 223.L, the result makes fork 223.L change 180 °, and sells 260 promotion guide frame 222L, makes erecting frame 226 upward movements.After the slide plate commutation, spring 262 makes fork get back to the first position that makes that retainer 263 limits.Two guide frames can align, so behind the fork commentaries on classics half-turn, erecting frame 226 has passed through the dead point of its support spring, is shifted onto another clamped position by spring force then.The situation of graphic other parts can be with reference to the explanation of figure 7 among Fig. 8.
The embodiment unanimity of embodiment fundamental sum Fig. 7 of Fig. 9 is so the explanation of Fig. 7 also can be used for this embodiment.But a reciprocal detaching gear is provided among the embodiment of Fig. 9, and this mechanism's energy braking return board 305 also can make slide plate 305 counter motions.Back and forth detaching gear comprises a pair of pull bar 335,336 for this reason, and pull bar 335,336 relative sides are limited moving rail 330.L and 330.R and stop rail 331.L and 331.R respectively.Each extends about half reciprocating travel moving rail 330.L and 330.R, promptly extends to the mid point of reciprocating travel.Moving rail is arranged essentially parallel to reciprocating travel, is contained in the opposite both sides of center line 334 between two sections reverse belts of belt 1.When moving rail is positioned at control position, they move erecting frame to the distance of center line 334 radius less than roller 322 between clamped position.And moving rail 330.R and 330.L are installed in respectively on half stroke, are positioned at one side of center line 334, move to terminal point near one section belt of midstroke on one side at this.
Stop rail 331.L and 331.R are installed in the both sides of center line respectively, and be relative with 330.R with cooresponding moving rail 330.L.Stop rail 331.R and 331.L with respect to the distance of center line all greater than radius of roller, but less than erecting frame 326 half of mobile distance between two clamped positions.
Moving rail 330.R and stop rail 331.L are positioned at same one side of center line 334, and moving rail 330.L and stop rail 331.R are positioned at the another side of center line 334, they all with firmly being connected that pull bar 335 and 336 is formed in conjunction with guide rail 333.Pull bar 335,336 is connected to each other with two parallel rods 337,338 at their two ends, by handle 339 parallel rod is rotated.Parallel rod 337,338 is hinged on the cooresponding fulcrum 340,341 for this reason.Fulcrum 340,341 is on the center line between two sections belts 334.
The service condition of present instruction diagram 9 embodiment.Driving handle 339, parallel rod 337,338 forwards to and is basically perpendicular to reciprocating direction, promptly perpendicular to the position of center line 334.Distance between aspectant moving rail 330.R of result and the stop rail 331.R, the distance between moving rail 330.L and the stop rail 331.L are all enough big, so when erecting frame was mobile between two clamped positions, roller 322 can not bump any rail.When repeat system moved, handle 339 remained on this position.
For slide plate 305 is stopped when belt 1 rotates, forward handle 339 to shown position, in this position, on one side moving rail and another side stop rail be positioned at from center line and keep above-mentioned qualification apart from part.Roller 332 one sides are slided along moving rail as a result, and another side slides into midway location along the stop rail again.This position has following characteristics: at first two chucks all lift from belt, so belt no longer drives slide plate 305.Secondly erecting frame 326 is positioned at and makes spring 320.L and 320.R leave their dead point lines, has promptly left the position of center line 334.And spring 320L and spring 320.R be positioned at along belt direction of travel and execute power-assisted position, and this belt continues to leave the mid point of the reciprocating travel that comprises the moving rail that matches and stop rail, the one section belt of this section belt above being exactly in Fig. 9.If slide plate is left half side reciprocating travel, erecting frame 326 will cross center line 334, makes spring 320.L and 320.R apply power to one section following belt.Parallel rod 337,338 rotates once more this moment, to guarantee that reciprocal slide plate arrival stroke one end in the past at least will be through half reciprocating travel.As a result, guarantee that thus the acceleration/accel that produces can carry out the speed that stroke turns to provides required for slide plate.
When the shutdown back planned to restart up-coiler, the slide plate that links to each other with single winding station can be positioned at any point on the reciprocating travel, and the handle 339 on each winding station forwards shown position to so.Minimum at interval at this position moving rail and stop rail, no matter where slide plate 305 is positioned at, this point be sure be that erecting frame moves to certain position, in this position, spring 320.L and 320.R apply power along belt direction of travel, and erecting frame as implied above must be at least through half stroke before arriving the reciprocating travel end points.Although the belt starting is slow, there is the enough time to carry out the speed that stroke turns to provides required to slide plate.The reversing arrangement that should be understood that Fig. 9 also can be used for Fig. 7 embodiment and below with the embodiment of Figure 10 of introducing.
Figure 10 has represented a yarn reciprocator, by the belt 1 of belt pulley 2 and 3 transmission ring-types, belt is rotated with arrow 4 indicated directions in mechanism.One slide-plate 405 is along sliding with belt parallel linear guides 406.The reverse side of slide plate 405 has a thread-carrier (not shown), thread-carrier make yarn along be parallel to drawing direction, on whole reciprocating travel, move back and forth.
Slide plate 405 is equipped with on fixed chuck 409.L and the 409R, and each chuck is positioned at the outside of belt.Retainer 423.L, the 423.R of swing rod form are housed at the two ends of stroke, and fork rotates around fulcrum 442.The sliding component 443 of pin or roller form is housed on the free end of fork, and retainer 423.L, the 423.R on the carriage can be along reciprocating direction, i.e. the direction of arrow indication motion among Figure 10.Carriage can be Fig. 7 and explanation that Fig. 9 introduces, and promptly can be contained on the mounting seat, and with the threaded shaft crank motion, threaded shaft can rotate.
Form the clamping mechanism driving device by erecting frame 426, erecting frame moves to clamped position by spring 420.L and 420.R, and erecting frame 426 is approximate rectangular flat boards that have slotted hole 445.Slotted hole along and skateboarding direction bevelled direction extend, intersect acute angle so the line of slotted hole and belt are the belt of each section arrival joint.The pilot pin 444 that is contained in securely on the slide plate 405 inserts slotted hole 445, and pin 444 makes erecting frame move between two clamped positions along reciprocating direction.
The both sides that erecting frame 426 is parallel to belt constitute movable chuck 412.L and 412.R.At the clamped position of erecting frame 426, among chuck 421.L and the chuck 412.R one is pressed on corresponding one section belt and cooresponding fixed chuck 409.L or 409.R clamp above-mentioned belt.
Crossbow incision 450.L and 450.R have laterally been opened in the reciprocating two ends of slide plate, and the concave surface of these otch is towards relative end point of travel.At the stroke turning point, the fixed stop 423.L of these otch and fork shape or 423.R engagement make slide plate slow down or acceleration at the stroke turning point.The quality of each fork is big, so when it is in a kind of state, as when forcing it to rotate, it just stores most kinetic energy, then it is passed to slide plate 405.
As shown in figure 10, when slide plate arrival stroke turning point, the side 422.R that the otch 450.R on slide plate right side is mounted frame 426 has covered a part.In the opposite side of slide plate 405, slide plate has covered erecting frame 426 cooresponding sides, and otch 450.L is whole have been exposed.In the illustrated embodiment, the curved side 422.R or the 422.L of erecting frame 426 play the guide frame effect, and promptly concave surface is facing to end point of travel.But there is a projection side near erecting frame 426 longitudinal midlines.
The operation of the embodiment of Figure 10 is described now, at shown position as seen, under the drive below, that clamped by movable chuck 412.R and chuck 409.R, the belt of stroke turning point motion to the right, slide plate slides along direction shown in the arrow 4.Static fork 423.R leans against on the retainer 447.Otch 450.R is processed into tangent with the sliding members 443 of fork 423.R basically, fork 423.R clockwise direction rotates as a result, and sliding members 443 moves along otch 450.R.So sliding members 443 also contact with the side 422.R of erecting frame 426, and thus, the slotted hole 445 of erecting frame is with respect to the shifted laterally along the belt operation of the pilot pin 444 of slide plate 405, thereby with chuck 412.R and belt disengagement.Because the surface-shaped structure of side 422.R makes erecting frame 426 avoid impacting.The projection of curved side 422.R bottom before the midway location between two clamped positions of erecting frame arrival, is passed to coriolis acceleration of erecting frame, to overcome the power of spring 420.R, 420.L, makes spring pass through dead center position.Erecting frame 426 under the effect of backspring power, automatically moves to the clamped position that chuck 412.L and 409.L clamp belt with respect to slide plate 405 then.Because top one section belt is towards the direction motion of leaving end point of travel, and the long guiding hole 445 of this section belt movement direction and erecting frame 426 acutangulates, and belt also applies power with respect to the sense of motion of slide plate to erecting frame along it, forces it to enter clamped position.So the gripping power that needs is not provided by spring 420.R and 420.L fully, it would be better to say that spring force mainly is used as mobile erecting frame 426 to clamped position and guarantee clamped position accurately.
The reciprocator that Figure 10 represents has a starter gear, and this device can be applied to above-mentioned reciprocator, thereby the following description and accompanying drawing also can be used for the embodiment that introduces previously.
Be parallel to each limit on relative two limits of two sections belts at slide plate 405, an acceleration guide rail 451 is all arranged.In the face of corresponding end point of travel, with respect to reciprocating direction, each quickens the guide rail both sides respectively a guide side and afterbody side, and its inclination angle is identical.Each quickens guide rail and a sliding members 452 matches, and sliding members can move along a trapped orbit, and this track is along the horizontal expansion of reciprocating direction.The most handy roller is a sliding members 452, is contained on the rocking bar 453.Bar 453 is arranged essentially parallel to reciprocating direction, is supported by the spring 454 perpendicular to reciprocating direction.If desired, rocker bracket 464 can move together with fork 423.L and 423.R, and fork plays the fixed stop effect, participates in the displacement of end point of travel.
When slide plate 405 entered the stroke turning point, guide's contacts side surfaces of roller 452 and acceleration guide rail 451 was along its upward movement.Because chuck 409.R and 412.R(or the 409.L and the 412.L of a pair of cooperation) continue to clamp belt, the result acts on stage clip 454 pressurizeds on the roller 452.Roller 452 faces down along the rear side of acceleration orbit and rolls then.So, spring 454 energy stored are transformed into the acceleration/accel of slide plate 405 towards end of run, because in this state, cooresponding cooperation chuck 409.L, 412.L(or 409.R, 412.R) no longer clamp belt.So a big masterpiece is used on the slide plate 405, there is enough power to make erecting frame must cross its dead center position, realize commutation.The embodiment of this commutation auxiliary device and Figure 10 advantageous particularly that matches, wherein the gripping power of fixing device is not to be provided by spring, but because self-locking action.
