Background technology
In real work, strip is subjected to repeatedly to move in the bar subchannel and the effect of power.Strip stands certain drawing-off between the bar tube of detaching roller and motion; It causes a pulling force, and strip moves through the bar subchannel to outlet from import by this pulling force.Because outlet is arranged in import certain axial distance is arranged, so outwards act on an additional centnifugal force because of rotatablely moving in strip upper edge side direction, centnifugal force may cause undesirable additional draft by " drum is protruding ".Outwards the centnifugal force of effect is suppressed with respect to the distance of rotation axis by reducing crooked bar subchannel, that is has reduced " drum is protruding ", and meanwhile inwall applies a counter-force on strip.This counter-force causes improving the friction of lamination coating and inwall, the possibility that influences the strip transfer rate thus and can not get rid of the additional draft that causes of friction.
Once the someone advised making with the corrosion-resistant steel of polishing and had the rotating disk that crooked bar subchannel and rate of delivery reach 1000m/min.But confirmed already, and can not further improve the strip transfer rate in this way and surpass 1000m/min.Especially for the drawing frame sliver of sensitivity, big friction force causes undesirable additional draft on inwall.
Summary of the invention
Therefore the objective of the invention is to create the rotating disk of the described type of a kind of preface, it has overcome above-mentioned shortcoming and especially can guide strip better and higher bar protonatomic mass is arranged.
According to the present invention, a kind of rotating disk that is used for the strip storing unit is proposed, this rotating disk comprises the bar subchannel that strip import and outlet are arranged of a curvature of space, wherein, it is neighbouring or coaxial with rotation axis that import is located at rotation axis, and outlet is located at import radial and axial distance is arranged, strip is subjected to drawing-off and has relative motion between the inwall of strip that transmits and bar subchannel, on strip, act on a friction drag by inwall in this case, it is characterized by:, can reduce friction drag to small part by changing mutual action and/or the spatial allocation between strip and strip vias inner walls.
Consider in the effect of different motion of strip channel lumen strip and power and act on motions different on the strip and power by measure of the present invention.These application forces are not all to occur with identical degree in all places.Therefore, by changing mutual action and/or the spatial allocation between strip and inwall, can overcome undesirable or interfering power one by one by partial sum, realize in this way significantly improving the strip guiding and improving the bar protonatomic mass, and especially in drawing frame, successfully realized improving greatly the strip transfer rate above 1000m/min.Especially in carding machine,, also can improve the strip guiding and improve the bar protonatomic mass by the present invention with same degree even the strip transfer rate is lower than 1000m/min.The strip especially drawing-off in its different segmentation or zone is very even.Partial draft and thereby partial draft more even to the effect in each segmentation of strip in the bar subchannel or zone, and improved drawing-off on the whole.

The specific embodiment
Lateral plan by Fig. 1 is represented entrance region 1, measurement zone 2, drafting assembly 3 and the strip storing unit 4 of (part) drawing frame (for example Tr ü tzschler-StreckeHSR).Establish the bar tube (circular bar tube) of drawing frame at entrance region 1, comprise two bar tubes rows in strip feeding plate 6 (creel) below, sliver feed pulls out and feeds drafting assembly 3 by feeding roller.Behind drafting assembly 3, enter the rotating disk 10 of can coiler through the strip of drawing-off, and become to enclose the land and leave in the output bars tube 11.Establish a subchannel 12 in rotating disk 10, bend pipe for example, strip 9 pass its and transmit.The operative orientation of representing drawing frame with A.Represent the calendering roller with 17a, 17b.
Fig. 2 represents carding machine (for example Tr ü tzschler-Hochleistungskarde DK 903), comprises that feeding roller, curtain formula feed a hair platform, licker-in, comber cylinder, doffer, stripping roller, squeezing roller, wire guide spare, fleece set exit skirt, detaching roller, with cover revolving flats, bar tube 11 and can coiler 20.The hand of rotation of representing roller with curved arrow.The operative orientation of representing carding machine with B.Shell is above the can coiler cover plate, and the rotating disk 10 of rotation is in this shell.During bar tube 11 is by rotating disk 10 filling strips 19 by a figure in the not actuating device motion of expression.Establish bar subchannel 12 in rotating disk 10, bend pipe for example, strip 13 pass its and transmit.
Press Fig. 3 a, bar subchannel 12 curvature of space also have strip 9 (seeing Fig. 3 b) import 12a and outlet 12b.Import 12a is set to rotation axis 16 coaxial, and outlet 12b is set to radial distance a be arranged and axial distance b is arranged with import 12a.Rotating disk 10 is located in the hole of plate 14 of stationkeeping.Rotating disk 10 has a strip guiding channel 12b, for example a bend pipe between strip import 12a and bar subexit 12b.Being located at bar subexit 12b in the false twisting plate of bottom has a kind of shape of cardinal principle ellipse.Strip 9 direction along arrow in bar subchannel 12 is moved, and enters bar tube 11 (see figure 1)s by bar subexit 12b.Represent ball bearing of main shaft with 15a, 15b.
Friction drag between strip 9 and the inwall 12c reduces by mutual action and/or the spatial allocation that changes between strip 9 and the bar subchannel 12 inwall 12c by the present invention.Here, inwall 12c " key " district X and Y are significant.For example in the regional X of strip 9 and inwall 12c and the friction between the Y, can by reduce coefficientoffriction, by reducing friction angle α and/or reducing by increasing radius of curvature r.Also can change the drawing-off (pulling force Z) of depending on detaching roller 17a, 17b and bar tube 11 speed.Take these measures to reduce thrust P one by one or in combination

Sending by rotating disk 10 of strip undertaken, the task of rotating disk be with the output strip 9 of sett frame or 13 cycloid shapes leave in the bar tube 14.Cycloid is by the formation that rotatablely moves that superposes two, and the fast speed that the first is implemented by rotating disk 10 rotatablely moves, and another is rotatablely move slowly (second motion is translation under the situation of rectangular strip tube) implemented by bar tube 11.In depositing process, strip is subjected to different power in pipe 12.They are pretension and friction force between strip 9 and inside pipe wall 12c that gravity, centnifugal force, drawing-off cause, and the sense of motion of the direction of friction force and strip 9 is opposite and thereby hinder the process of depositing.In order to obtain the output condition of rule, should measure drawing-off, make the strip in the pipe 12 be in tension state all the time.Therefore in the buckled zone of pipe 12, strip always abuts on the less inside radius of each crooked segmental arc male bend.Above-mentioned friction force mainly produces by the mutual action between strip and the pipe at these contact zones X and Y.The negative effect to machine run characteristic and bar protonatomic mass that has illustrated, especially outstanding behaviours is in the friction between strip 9 and the pipe 12 inwall 12c.
In order to improve the guiding of strip in rotating disk pipe 12, take following measures one by one or by the form of combination.
Reduce the loss due to friction between lamination coating and the strip guide mechanism inside face, it is made by the section coating or with the material of low friction in the strip guide mechanism.Can for example reduce drawing-off in this way and thereby avoid additional draft.
The geometry design of strip guide mechanism is to avoid lamination coating to roll along the circumference of strip guide mechanism.
Especially expand in the geometric configuration of entrance region 12a strip guide mechanism 12.For example strip 9 or 10 is reduced to minimum level with contacting of strip guide mechanism 12 influencing under the situation of tension force thus.
On strip 9 or 10, add external force (for example by causing magnetic field or electric field).For example should reduce the friction between the surperficial 12c of fiber and guiding fiber thus.
Because the strip load fluctuation that strip caused when depositing is by an in check actuating device, for example the bar tube is compensated.
The strip guide length reduces by appropriate design rotating disk guide mechanism.
These are used for being reduced in, and inhomogeneity measure can be applicable to drawing frame, carding machine, scribbler in the strip guide mechanism.
Basic thought of the present invention is that not allowing and forming contact force (particularly is P
1And P
2), as long as have in the contact zone X and Y that turns to, strip 9 is separated from each other with inside pipe wall 12c by an air curtain in the transmission of strip.For reaching this point, sliver pipe 12 partially perforations or seam.Introduce the air-flows act in the pipe 12 thus from outside to inside, air-flow presses off strip and thereby reduce contact force and friction force from inside pipe wall 12c.The hole in slit can be designed to locate with respect to the tube wall quadrature or along the direction that strip transmits.Air curtain can cause with diverse ways:
For example, slave mode, by utilizing the conveying effect of the centnifugal force that in the pipe 12 of rotation, causes, or by utilizing the pressure reduction that exists.
For example, active, by blowing from the outside.
Especially should produce a kind of like this air-flow, a parapodum is enough strong therein for it, so that make strip 9 cause actv. to separate with tube wall 12c, but it does not splice because of fiber commutation causes at opposite side, because incidently will be the loss of fibre orientation aspect and worsen spinnability with splicing.The appropriate position of the latter by the hole on tube wall, size and Orientation and prevent by correct qualification amount of air.
Press Fig. 4, bar subchannel 12 has some hole 12e.Outside face 12d round bar subchannel 12 establishes a sealed tube 18, connects one (not representing among the figure) compressed gas source on sealed tube.Compressed air stream C enters bar subchannel 12 inner chambers from managing 18 inner chambers by hole 12c, and strip 9 is pressed off from inwall 12c.
Press Fig. 5, compressed air stream D enters the inner chamber of bar subchannel 12 obliquely along direction F, and thereby support throughput direction.Hole 12c only is located in the key area, for example in regional X and Y.
