The specific embodiment
According to the free-end spinning machine 1 of Fig. 1, it has two machine sides 2 and 3 that are provided with by a central longitudinal plane symmetry.On each machine side 2,3, be mounted with many similar spinning organs that are in line each other 5.These spinning organs 5 comprise as Fig. 1 all briefly by the illustrated input unit of rectangle, fibre-opening unit having and twist device by known manner.
Free-end spinning machine 1 comprises a headstock 6 or 7 at each end face, is mounted with transmission device and other feedwaies by known manner in this headstock.
To elaborate to accompanying drawing below, a movably slide plate 8 is arranged at the bottom of each spinning organ 5 on each machine side 2,3.In these two slide plates 8 each is according to vibration-direction A and B, and the tractive band made by a spring steel 9 vertically moves continuously along machine.
Two drive motors 10 and 11 are respectively applied for the reciprocating motion of two slide plates 8, and the winder 12 of motor and 13 arrangement are to be used for the tractive band 9 that thin steel band is made.Tractive band 9 is wound up on winder 12 and 13 when the reciprocating motion with mapping mode instantaneously.When slide plate 8 arrived a headstock 6 and 7, each operating drive motor 10 and 11 cut out its driving via the control device of not representing on the figure.
Two slide plates 8 that this also will describe in detail hereinafter are used for impurity and carry, and these impurity are isolated downwards by each spinning organ 5.The groove that slide plate 8 also will describe in detail after these impurity are moved to is transported to suction point 14 and 15 of a headstock 6 or 7 always.Impurity at this suction point 14,15 by pneumatic discharge in groove and be sent to a central filter chamber.This moment, each tractive band 9 also can obtain cleaning.Be placed in the negative pressure source of headstock 6 and 7, for example vavuum pump 16 and 17 is used for the generation of negative pressure, and this negative pressure is monitored.
From Fig. 2, three side diagrammatic sketch of 3 and 4 are clear that spinning organ 5 all comprises a fibre-opening unit having 18, dispose an opening roller 19 that rotates by direction of rotation C.Opening roller 19 disposes combing card clothing 20 by known manner, and its effect is that the ribbon branch of an input is combed into single fiber, and and then these single fibers spin with twist mechanism of unshowned formula input.Each opening roller 19 rotates in an opening roller case 21, and this case also has the guide surface around opening roller 19 circumference.
Be placed in the place ahead of opening roller 19 by a feeding roller 22 of D direction of rotation rotation.This feeding roller and feed plate 23 collaborative works, this feed plate presses on feeding roller 22 by the ribbon of a loading spring 27 with feeding.For this reason, feed plate 23 can rotate around rotating shaft 24.Feeding roller 22 these sides by known manner, are mounted with a loading hopper 5 that is used to feed ribbon in its front.
The end of the ribbon that has fed is clamped in the jaw place between feeding roller 22 and the feed plate 23, and the fiber that produces must be combed into single fiber in 19 minutes by opening roller by clump constantly here.These single fibers arrive in the cup that is in negative pressure that does not illustrate among the figure at this place's fiber till being transported to fiber transmission channel 26 along the circumference of opening roller 19.
The single fiber that combs out when branch is during along with the circumference operation of opening roller 19, and heavier impurity is subjected to the centrifugal action of combing card clothing 20 and is discharged from.These impurity are isolated by the impurity separating opening 28 that is arranged in opening roller case 21 by known manner.
Groove 29 by the machine longitudinal extension is arranged below the impurity separating opening 28 of each spinning organ 5, and impurity is collected in this groove.The cross section of groove 29 is U-shaped substantially, and the opening of this shaped piece is facing to shredding rod 19.Groove 29 extends to the suction point 14 and 15 in headstock 6 and 7.
Being collected in the reciprocating slide plate 8 that the impurity in the groove 29 addressed by the front pushes as snowplow up to suction point 14 and 15 places.The weight of slide plate 8 can be measured fully.From avris sliding surface 30 and 31, this sliding surface is used to be positioned at the guiding of the slide plate 8 on the sidewall 32 and 33 of groove 29, and the width of slide plate 8 is the whole bottom of enough topped groove 29 almost.
Slide plate 8 has oblique spade slide plate face 34 and 35 with the back and by the each run direction in front, and this slide plate face can be provided with a wear-resisting liner 36 or 37 when needed. Slide plate face 34 and 35 directly is not posted by on sidewall 32 and 33, because there are sliding surface 30 and 31 in this place, they stop the inclination of slide plate 8.Therefore, slide plate 8 here is shorter than at another sidewall 33 over there slightly at sidewall 32, and slide plate face 34 and 35 is oblique moving facing to the direction of motion all the time like this.Being transverse to the slide plate face 34 and 35 that groove 29 moves sideling can make slide plate 8 better slide past the presumable partitioning slot of groove 29.
Also can know from Fig. 2 and Fig. 3 and to see that be mounted with a rubber stripping device 38 on slide plate 8, it is used to clean the sliding surface 39 and 40 of the opening roller case 21 when reciprocating motion.
Because tractive band 9 is wound up on aforesaid winder 12 and 13 corresponding to vibration-direction A and B conversion ground when its reciprocating motion, thereby conforms with purpose and be, use a kind of that especially approach, such as the thick steel band of 1mm.This steel band briefly is shown among Fig. 5.We see among the figure power transmission shaft 41 and 42 of two drive motors 10 and 11, the slide plate 8 of this moment be sitting at drive motor 11 near.Therefore on the winder 13 around full tractive band 9, and another winder 12 intact this tractive band of unwinding almost.When slide plate 8 by vibration-direction B when headstock 6 returns, winder 13 just reverses and carries out unwinding, the winder 12 full tractive band 9 of then reeling.
In case slide plate 8 arrives headstock 6 or 7, these two drive motors 10 and 11 just disconnect respectively, and then connect another drive motor 10 or 11 respectively.This is by each direction of rotation E, and F, G and H represent that wherein just in time off-duty driving machine 10 or 11 is subjected to the tractive of tractive band 9 these sides, shown in dotted arrow F and H.Two drive motors 10 are connected with a controlling organization 43 with 11 for this reason, the above-mentioned connection of the corresponding control of this controlling organization.
Since winder 12 and 13 different coiling degree, and in the zone of winder 12 and 13, settle a directive wheel 44 and 45 respectively, and its setting is that tractive band 9 is on the base plate of groove 29 under abutting in all the time.
With dashed lines 46 and 47 indicates that slide plate 8 reaches the position before a suction point 14 or 15 among Fig. 5, and on this position, running drive motor 10 or 11 is from the first transmission revolution n 1Be transformed into second a lower transmission revolution n 2
This rate conversion is that the chart according to Fig. 6 carries out the movement velocity V of slide plate 8 1, the speed when promptly being in the continuous reciprocating motion between position 46 and 47 is reduced to the corresponding second lower movement velocity V simultaneously 2From the position 46 and 47, i.e. this position of a little centimetre only before suction point 14 and 15, slide plate 8 is to a certain degree moving to suction point 14 and 15 by the low speed stroke, this locate and the setting in motion wraparound to another vibration-direction A or B.Can be as can be seen from Figure 6, the spot speed in these swivel point positions is 0.
This revolution or velocity rate should be selected like this, i.e. movement velocity V 2Should be lower than movement velocity V 130%.Movement velocity V for example 2Before reaching a suction point 14 or 15, be about 10cm each second.
What need emphasize here to indicate a bit is, slide plate 8 when backhaul naturally immediately with higher reciprocating motion speed V 1Operation, and do not illustrate among Fig. 6.
