The object of the present invention is to device for continuous centrifugal spinning.
It is known in centrifug-al spinning, that the fibres after orientation are deposited on the inner surface of a rotating centrifugal drum and are thus converted into yarn which is pulled olf Ithrough the opening of the spinning centrifuge.
The yarn cornes into being through deposition of the libres in the point of maximum diameter of the inner circumference of the centrifuge and, when pulled off, rolls over the inner surface of the centrifuge or over the surface of an auxiliary rotationg -body within the centifuge, if such a body is provided, while simultaneously moving towards the outlet opening and beyond the same to the winding mechanism. This arrangement is disadvantageous because the yarn is excessively stressed by tension resulting from friction developing during the composite movement just described whereby twist-olf occurs in the yarn to an extent undesirable for textile processing.
Other centrifugal spinning arrangements are known, in which the yarn -moves loosely through the centrifuge in the zone which lies between the maximum diameter of the inner circumference thereof and the delivery opening. The disadvantage of these arrangements is that the yarn, which now has no contact at all with a supporting surface, is fully exposed to the effect of centrifugal force, resulting in excessive tensioning of the yarn and undesirable yarn breakage. This also makes it impossible to increase the speed of yarn take-up which otherwise is evidently desirable.
An embodiment of the present invention is diagrammatically shown by way of example in the accompanying drawings, in which- FIG. l shows a vertical section through a spinning centrifuge embodying the invention;
FIG. 2 a vertical section through another spinning centrifuge, embodying the invention and shown mounted rotatably on a stationary delivery tube;
FIG. 3 a vertical section through the spinning centrifuge with a stationary delivery tube,A said tube being equipped with two inlet guides;
FIG. 4 a vertical section through a spinning centrifuge embodying yet a further modification including a stationary delivery tube equipped with after-twist channels; and
FIG. 5 a horizontal sectional taken in FIG. 4 in the plane of the after-twist channels.
The spinning centrifuge in FIG. 1 is fixed on a tubeshaped guide 2 through which loose fibres 3 are fed into the interior of centrifuge 1 which will be seen to be rotatably mounted on the bearings 4 in the body y5 of a spinning machine. The upper portion of the centrifuge 1 is coniigurated in form of a pulley which may be driven by a drive belt (not shown) of the machine. The spinning centrifuge 1 expands conically downwards to an area 13 of maximum diameter, after which it slightly narrows towards its bottom wall in which opening 6 is provided concentric with the axis rotation. The conically shaped portion of the spinning centrifuge 1 can be provided with openings 7 for facilitating the escape of the inserting medium used |to introduce the libres 3. The stationary delivery tube 8, through which the yarn 9 forming in the plane of maximum diameter is pulled olf, is firmly connected with its shank 10 to the machine and 3,328,949 Patented July 4, 1967 comprises a portion which is located inside the spinning centrifuge and which is congurated in the shape of a funnel 11, having a rim so positioned as to be located substantially in the plane of the area of maximum inner diameter 13 of spinning centrifuge 1. Below the outer free end of delivery tube 8 there is arranged a known winding mechanism (not shown).
In the embodiment of FIG. 2, the spinning centrifuge 1 is freely mounted on the shank 10 -of the stationary delivery tube 8 by means of bearings 14, and the tube 8 in turn is fastened to the vbody 15 of the machine. Guide 16 extends into the spinning centrifuge through opening 6, which is situated in this embodiment in the upper wall of the centrifuge, and the fibres 3 are introduced through this guide which can be stationary and is advantageously provided with a screen 17 for preventing the loose libres 3 from penetrating directly int-o the funnel-shaped flange 11 of the delivery tube 8. The bottom part of the spinning centrifuge 1 shown in FIG. 2 is congurated in form of a pulley 18 by way of which the centrifuge can be rotated. The rim 12 of funnel 11 is located substantially in the plane of the area of maximum inner diameter 13 of spinning centrifuge 1.
In the embodiment in FIG. 3, the means for feeding loose fibres as well as the means for withdrawing yarn 9 both communicate with the same axial end of the centrifuge, and said means is constituted by a stationary delivery tube 8 with two fibre guides 19, the orifices of which are ben-t towards lthe inner peripheral surface of the spinning centrifuge 1.
The shank of tube 8 and the guides 19 form a firm assembly, which is stationarily mounted on the body 15 of the machine. Because of the provision of tube 8 and guides 19 at one axial end of the centrifuge, the drive pulley for the latter is provided at the other axial end.
In the embodiment in FIGS. 4 and 5, the shank 10 of the stationary delivery tube 8 isequipped with a multichannel nozzle 20 whose channels lead tangentially into the opening 21 through which the delivered or withdrawn yarn 9 passes, said channels being connected lto a known source of pressure medium (not shown) e.g. compressed air.
In all embodiments shown the delivery tube 8 leading into funnel 11, is thus stationary in view of the spinning centrifuge 1 and the rim 12 of the funnel-shaped flange 11 is substantially coincident with the plane of the area 13 of maximum inner circumference of spinning centrifuge 1. V
The device according to the present invention works as follows:
The loose fibres 3, entrained by the carrier medium, e.g. an air iiow are conveyed into the rotating spinning centrifuge 1. These fibres 3 can be of a different staple and need not previously pass through the known drafting systems, so that libres obtained from carding or corresponding processes can be used in the novel centrifuge. The fibres 3 are exposed to the effect of centrifugal force on entry into the spinning centrifuge 1 and are deposited on the inner surface of centrifuge 1 in the area 13 of maximum inner diameter under simultaneous orientation-it being understood that the fibres are fed into the centrifuge at a speed less than the circumferential speed thereof at the area 1 3. The inserting medium, freed from the fibres, escapes from the spinning centrifuge 1 through the space between funnel-shaped flange 11 of the stationary delivery tube 8 and the edge of the concentric opening 6 of spinning centrifuge 1, or through openings 7 in the conical portion of spinning centrifuge 1, respectively.
'I'he yarn 9 is formed in such a way, that the fibres, held by centrifugal force in an oriented state inside the centrifuge, join the trailing end of a yarn which has been inserted into the spinning centrifuge 1 through the opening of the stationary delivery tube 8 and which is pressed by centrifugal force to the inner wall surface of centrifuge 1. Thereupon, the yarn 9 is continuously drawn off from the centrifuge 1 and wound onto a bobbin situated outside the spinning centrifuge, whereas additional loose iibres are continuously introduced into the spinning centrifuge 1 through the guide 2. The tension of that yarn portion which extends between the inner wall surface of the centrifuge and the outlet opening thereof is determined by the stationary funnel shaped flange 11, on whose rim and surface the yarn is guided until it passes into shank and from there to the winding mechanism. Thus, provision of the funnel-shaped flange 11 shortens considerably the length of the unsupported yarn portion within the centrifuge so that the yarn is less effected by tensional stress, which in turn makes it possible to increase the withdrawal speed of the yarn.
In the embodiment of FIG. 2 the working procedure of the device is analogous with that described above, except for the fact that guide 16 does not rotate and is provided with a screen 17, preventing the undesirable deposition of the fibres 3 directly onto flange 11.
The embodiment of FIG. 3 also works in the same way, except that feeding of the loose fibres 3 as well as withdrawal of the yarn 9 are accomplished from one axial end via the stationary delivery tube 8, provided e.g. with two guides 19. In this embodiment the inlet opening and the outlet opening of centrifuge 1 are concentric.
The embodiment in FIGS. 4 and 5 makes possible an increase in the withdrawal speed and in the after-twisting of yarn 9 and this is accomplished by the provision of an air nozzle consisting of several channels 20, which lead tangentially into the withdrawal passage 21 of the stationary delivery tube 8. In this passage 21, yarn 9 is exposed to the twisting effect of air entering the passage under pressure through the channels 20 and is thereby twisted intermediate the nozzle and the spinning centrifuge. Not only is the yarn in the spinning centrifuge lapped more quickly, but it is also after twisted to an extent which is sometimes desirable for technological reasons. By changing the intensity of the air ow it is possible to control the twisting effect of the nozzle.
