Abstract
The invention provides a kind of batch up gear that can carry out high-speed wind-up, can prevent the inappropriate automatic winder of package generation shape.
The batch up gear of automatic winder is after many yarn feeding bobbin joints, and batches by the revolution of reciprocal drum from package just begins to reel and its coil diameter correspondingly increases coiling speed control setup.
Description
The present invention relates to the batch up gear of automatic winder, particularly relate to the batch up gear of the automatic winder of the package shape when improving high-speed wind-up.
Be provided for the automatic winder of next process and when recoiling with the yarn feeding bobbin of spinning frame productions such as ring throstle, Yi Bian remove the yarn defect in the yarn, Yi Bian recoil into the package of definite shape with given amount of thread.In order to obtain a package, to use several～tens yarn feeding bobbins usually.This automatic winder is that a plurality of batch up gears are set side by side, and mechanism's configuration of a batch up gear U is described by Fig. 5 here.
In Fig. 5, the yarns Y of pulling out from yarn feeding bobbin 1 unwinding by air ring breaker 2, tensioner 3 after, on one side by the yarn defect detection head check yarn defect of bobbin-winding machine yarn clearer 4, batch on one side in the package 6 of rotating by the reciprocal drum 5 of thread-carrier.In coiling process, electric signal 7 is made in the change of the thickness of yarn degree by bobbin-winding machine yarn clearer 4, be input to clearer regulating control 8, according to the comparison operation of a reference value, when surpassing the scope that allows, be judged as the part that the yarn defect passes through, from regulating control 8 command signal 10 is input to cutter 9 immediately, make cutter 9 actions, cut off yarn.Along with yarn cuts off, by above-mentioned bobbin-winding machine yarn clearer 4 yarn is introduced signal 11 and cut off,, after the perception yarn cuts off, halt instruction is input to drum CD-ROM drive motor 12 by regulating control 8, reciprocal drum 5 is stopped operating.Then, allow behind the command signal 13a of piecing devices 13 beginning joints actions, carry out joint by regulating control 8 output.Wherein, the 14th, detect the pulse generating unit that reciprocal drum 5 rotates, for example can be by the magnet and the proximity sense fixed length mechanism that constitute, that be applicable to the length of yarn that batches by the revolution calculating of drum that are fixed on the drum part end face.
And back and forth the CD-ROM drive motor 12 of drum 5 is arranged on each batch up gear U, by the rotating speed that is arranged on the coiling speed setting device 18 control motors 12 on each batch up gear U.That is, the control setup 19 that CD-ROM drive motor 12 is turned round with the rotating speed of the state that batches that is suitable for each batch up gear most is being set all on each batch up gear U.By the control signal 20 that this control setup 19 sends, set the rotating speed of CD-ROM drive motor 12 by coiling speed setting device 18.Control signal 20 is to make CD-ROM drive motor 12 startings, the signal that stops.And, the control of whole batch up gear U of automatic winder or each among a plurality of batch up gear U is then undertaken by the coiling speed setting device by central control unit 21 extended signal wire (SW)s 22,23, be that whole batch up gear U are those signals, for example set connection that the anti-patterning device of basic yarn speed or bobbin-winding machine uses, cut-off signal etc. as common control according to handled yarn variety.
Batch up gear U also has at position of readiness B except the yarn feeding bobbin 1 that batches on the A of position is arranged
1, B
2On two the preparation yarn feeding bobbins 1.Yarn feeding bobbin 1 on batching position A becomes when empty, and the yarn that the yarn clearer 4 of bobbin-winding machine transmits is introduced signal 11 and just is interrupted, this state and by tensioner 3 etc. yarn is cut off can not to differentiate.For this reason, confirm to have or not bottom line, carry out yarn feeding bobbin with the sort of signal 24 that does not have bottom line and detect with electronic yarn clearer 27.The bare bobbin 1 ' discharge of batching on the A of position, replace position of readiness B
1On yarn feeding bobbin 1 input.And loose thread Y
1Blow afloat, the bobbin-winding machine center coupling pipe that is provided with expression by figure is transported to piecing devices 13, and the upper thread of package 6 simultaneously also is transported to piecing devices 13 by the vacuum yarn-feeding port that does not have expression among the figure, carries out joint.Then, begin batching of new yarn feeding bobbin 1.Like this, usually by several～tens yarn feeding bobbins 1 around being rolled into a package 6.
The action of batching of above-mentioned batch up gear U is described with the diagram of curves of time-coiling speed of Fig. 6.The A point is that the coiling of package begins, and the coiling of B point expression package finishes.For simply, illustrated embodiment represents to be wound into three yarn feeding bobbins the situation of a package, begins the point to C from the A point, and expression rises to given coiling speed V
0; Yarn feeding bobbin begins to represent with certain given coiling speed V till become empty D point from the C point
0Batch.And, replace (from the E point to the F point) and afterwards, proceed to batch carrying out bobbin with the same style of batching.The centre is carried out the line defect and is removed, and the just style of formation as the long and short dash line that the G point → the H point → I point → J is ordered, thereby line defect removed often, and the time of batching is just long.
The capacity rating of this batch up gear U depends on coiling speed V to a great extent
0, but the practical coiling speed V of former batch up gear U
0Have only about 1000 meters/minute.Its reason is along with coiling speed increases, unwinding tension also just increases, especially become at 1/3 o'clock from the residue unwinding amount that is called as 1/3rd coiling amounts, yarn diminishes from the unwinding angle of the cop top conical surface part 1b of yarn feeding bobbin 1, the factors such as friction of friction between the yarn, yarn and tube core 1a swash unwinding tension to increase suddenly, also frequent simultaneously generation cop collapses and takes off, and these all can cause tension force to cut off.
Increase in order to suppress this unwinding tension, once proposed to use shown in the long and two-short dash line of Fig. 6, make coiling speed be increased to V
1, concerning a yarn feeding bobbin, to becoming blank (promptly from the K point to the L point), make coiling speed decline near 1/3rd coiling amounts, thus the batch up gear that tension force is reduced gradually.In addition, also proposed the shape of the air ring breaker 2 of Fig. 5 and action are improved, suppressed the batch up gear that unwinding tension increases.In such batch up gear U, realized high-speed wind-up in recent years.
But, in high-speed wind-up, in package, especially in the less package that begins to reel of coil diameter, be collected at inappropriate problem of central authorities with regard to easy generation layer as shown in Figure 7.
The present invention creates in the process of the reason that central authorities gather at generation layer in the package when the research high-speed wind-up, its objective is the batch up gear that a kind of automatic winder is provided, its energy high-speed wind-up, and also it is improper to suppress the generation of package shape.
To achieve the above object, the batch up gear of automatic winder provided by the invention is in the batch up gear that batches after many yarn feeding bobbin drive connectors in the package of being rotated by reciprocal drum, the revolution that makes above-mentioned reciprocal drum is being set from the package coiling speed control setup that coil diameter with package increases accordingly that just begins to reel.
As shown in Figure 3, the speed of the yarns Y of in the package 6 that the reciprocal drum 5 that by circumferential velocity is V rotates, reeling yes V.This yarns Y is outwards heaved under centnifugal force F effect.This centnifugal force F=mx(V
2/ R).Wherein, m is that unit mass, the R of yarn are the radius of a circles that yarn will form.That is, the high speed of coiling speed V becomes a square ground influence to centnifugal force F, supposes that speed increases by 1.2 times, and then centnifugal force just increases by 1.44 times.And centnifugal force and radius are inversely proportional to, and bigger centrifugal action is arranged when beginning to reel.Therefore, coiling speed one improves, and when beginning to reel in package, yarn will be subjected to centrifugal action and past external drum, thereby just occurs in the phenomenon that package central authorities gather.So, layer little in coil diameter gathers package when central authorities easily, adopts low speed to reel, by with coil diameter correspondingly speedup come inhibit function to increase to the centnifugal force on the yarn, thereby do not increase because the yarn that centnifugal force causes is not outwards heaved.

1/ D
0) also increase into 1.44 times.Owing to act on the centnifugal force F=mx(V on the yarn
2/ R), thereby centnifugal force does not just increase.。Wherein, coil diameter D
1The degree that depends on high-speed wind-up, according to different situations, also can be from the D that begins to reel
0To the D that reels and finish
mGradually speedup.In addition, because centnifugal force phase * increases for coiling speed square ground, thereby the speedup curve of coiling speed is not the straight line shown in the solid line, preferably the downward protruding quadratic curve shown in the image point line.
Below, with the action of batching of the above-mentioned batch up gear U of shown in Figure 4 time-coiling speed diagram shows.Fig. 4 is and the corresponding figure of the Fig. 6 that represents former example.A point expression package begins to reel, and B point expression package is reeled and finished.To the C point, make winding speed rise to the coiling speed V of regulation from the A point
0, becoming blank some D from the C point to yarn feeding bobbin is to batch with the speedup curve of stipulating.And, batch interruption carrying out making during bobbin is replaced (from the E point to the F point), but the K point after rising with coiling speed begins, proceed to batch with same speedup curve again.And become D from coil diameter
1The time some L all be when reel finishing with certain coiling speed V
mBatch.In order to carry out high-speed wind-up (V
m), as long and two-short dash line, for a yarn feeding bobbin, can carry out from 1/3rd coiling amounts as before with reducing speed now.
Get back to Fig. 1 now, explanation can be carried out the apparatus for unwinding 30 of high-speed wind-up.This apparatus for unwinding 30 is by the cylindrical shell 31 on the Gai Zaixin pipe 1a, the necking down 32 on cylindrical shell 31 tops and sensor 33, and the actuating device 34 of these member liftings is constituted.After the signal that sends from the sensor 33 of the position of detecting cop top conical surface part 1b is imported into regulating control 8,8 pairs of actuating devices of regulating control, 34 output action signals, then the distance L between cylindrical shell 31 lower ends and the cop top conical surface part 1b roughly is held in necessarily, is maintained in the unwinding angle θ of yarn bigger.Necking down 32 is placed the top of core pipe 1b, make the air ring of upside yarns Y stable.Be with the cylindrical shell 31 of necking down 32 to suppress the increase and the change of unwinding tensions by this, make high-speed wind-up become possibility.
The batch up gear of automatic winder of the present invention has the revolution that makes reciprocal drum from package begins to reel and its coil diameter correspondingly increases coiling speed control setup, when gathering, package central authorities reel easily by, layer less with low speed in coil diameter, with coil diameter speedup correspondingly, the just increase of the centnifugal force of energy inhibit function on yarn, reduce owing to centnifugal force causes yarn and outwards heave, thereby can prevent because high-speed wind-up causes the package shape defect.
