(Cl. 19--159) ABSTRACT OF THE DISCLOSURE A textile sliver planetary coiling mechanism in which an uncoiled sliver is fed between driven calender rollers, mounted in a stationary position, into a feed tube which leads the sliver down to a pair of driven co-operating feed belts arranged to pass the sliver to a feed opening. The belts are rotated by gearing in a circular path about a central axis at a slow speed with the feed tube, and the belts are further rotated about their inlet end about a second ofi-set axis at a faster speed to deposit a plurality of sliver coils progressively in circles into a stationary can.

This invention relates to methods of, and mechanism for, coiling textile slivers in cans.

In some cases top mechanism coils a sliver into a slowly rotating can but this invention is concerned with an arrangement of planetary coiling which performs the whole of the coiling operation and deposits the coiled sliver progressively into a stationary can. The latter arrangement has been developed mainly for use with high speed carding machinery.

Although what is considered to be efficient mechanism has been developed, so far the construction has been rather expensive and it is a main object of the present invention to provide an improved method and mechanism of a less costly type.

Acording to the present invention there is provided a method of coiling a textile sliver into a can, consisting in arranging a sliver to pass from a pair of driven calender rollers mounted in a stationary position into and through a feed channel capable of rotating about a verticalaxis which passes through the nip of said rollers and channel inlet, arranging the outlet end of said channel to deposit the sliver between a pair of superposed endless driven belts capable of rotating bodily about the same axis as the channel, causing such belts to direct the sliver longitudinally thereof and radially outwardly from said channel to their delivery end, arranging the feed belts to be also rotatable about another vertical axis adjacent their inlet ends, and causing the whole assembly to rotate slowly about the first axis and the belts at a faster speed about their own axis.

The invention also includes sliver coiling mechanism of the depositing type incorporating a mounting means for a pair of hollow hubbed horizontally disposed members mounted to rotate both about a common vertical axis which is that of the first member with the second member rotatably carried by the first member and capable of rotation its own offset vertical axis, a pair of superposed endless feed belts mounted in the structure of the second member and radially of its axis, a driving shaft with gearing to drive the first member at a slow speed and a train of gears to drive the second member at a faster speed, said latter gearing being rotatable about the aforesaid first axis, gearing to drive the belt-s from said first member, a sliver feed tube leading from a sliver inlet on said first axis to at least adjacent the otf-set axis of the second member and feed ends of the belts, and a 3,345,703 Patented Oct. 10, 1967 pair of calender rollers mounter in a stationary position above the sliver inlet to the feed tube.

The invention will now be more particularly described with reference to the accompanying drawings, in which:

FIG. 1 is a plan view from above of the coiler mechanism; and

FIG. 2 is a sectional side view of the mechanism.

In the illustrated embodiment of this invention, the coiling mechanism includes a cover 1 furnished with a circular opening 2 in its base and a bearing 3 in the top bridge member 4, said bearing being in axial alignment with the bottom opening 2. This member 4 is carried by a tubular support 5 at one end and a tubular column 6 at the other end, which column houses the driving shaft 7. The hollow hub 8 of a large gear wheel 9 (forming a first rotary member A) is arranged to rotate in said top bearing with the base 10, which is suspended from the gear wheel 9 by bolts 11, rotatable in said bottom opening 2 of the housing. There is a circular opening 12 in the base 10 with a bearing 13 in the gear wheel 9. This bearing is in axial alignment with the bottom opening 12 and their axis 14 is oif-set radially from the axis 15 of the hollow hub 8. In the bearing 13 there is mounted a hollow hub member 16 provided with an integral gear 17 (forming a second rotary member 13) and a mounting bracket 18 to which a base 19 is attached. This bracket 13 incorporates a pair of feed belts 20, 21 mounted on

pulleys

22, 23, 24 and 25, respectively and arranged to be in running engagement with one another. The top belt 20 is oif-set longitudinally so as to provide an upwardly facing entrance 26 between the

forward pulleys

22, 24 for the entry of a sliver when it passes down the delivery tube 27 which is mounted in the wall of the hollow hub 8 at its upper end and in the hollow member 16 at its lower end. Thus the sliver delivered to the belts will be carried along between them and out through an opening 28 provided in the base 19. The base 19 may be displaceable, or include a displaceable part, to give access to the interior of the housing 18 particularly for cleaning purposes. These belts may be driven by connecting the two

forward pulleys

22 and 24 by gear pinions.

29 and driving the shaft 30 by meshed bevel gears 31, upright shaft 32 and top pinion 33 which is in mesh with the gear ring 34 carried by the gear Wheel 9. Belt cleaning means may be mounted to press against the belts 20, 21.

Both the first and second members A and B require to be driven with the second member B rotating about its own axis 14 at a faster speed than it rotates with the first member A about the first axis 15. Thus the vertical driving shaft 7 is furnished with a gear pinion 54 in mesh with atop gear wheel 35 which drives a bottom pinion 36 which meshes with the gear wheel 9 to drive this first member A at a desired slow speed. The faster speed of the second member B is achieved by the upper gear wheel 35 meshing with the first of a pair of engaged horizontal gear wheels 37 and 38 with the second gear wheel in mesh with a

double sun wheel

39, 40, mounted to rotate about the axis 15 of the hollow hub 8 of the first member A. The bottom gear 40 of the sun Wheel is arranged in mesh with the gear wheel 17 on top of the hollow hub member 16 of the second member B carrying the feed belts 20, 21. Whilst the

double sun wheel

39, 40 is positioned correctly in FIG. 1 it is out of position in FIG. 2 for illustrative purposes. Thus from a common driving shaft 7 in the colume 6 the two members A and B can be driven by gearing in a simple manner and a drive furnished to the feed belts.

The above sliver feed tube 27 is straight (it may be curved or sinuous) in its inclined length for the free movement of a sliver therethrough. Said tube has its inlet and in the inlet 42 to the hollow hub 8 of the first member, passes through the wall of said hub and has its bottom outlet end immediately above the nip of the

front belt rollers

22, 24, and adjacent the aforesaid second axis 14. A pair of driven calender rollers 43 are associated with the aforesaid mechanism and located in a stationary position immediately above the inlet end of the feed tube 27.

' The calender rollers are driven from the drive for the coiler mechanism and conveniently a secondary vertical shaft 44 is driven from the aforesaid gear wheel 37 by a pinion 45. This secondary shaft drives a horizontal shaft 46 through bevel gears 47 in a top housing 48. This horizontal shaft drives one of the calender rollers 43 direct with the other roller geared thereto through a pair of gears 49. One or both rollers may be mounted to be displaceable about the axis of the shaft 44 and/or mounted for separation.

The cover 1 as shown comprises a fixed botom ring and a cover which is divided into two halves hinged together on the pin 50 carried by the top bridge member 4.

In smaller constructions the bridge member 4 can be reduced to the form of a half cross member projecting from the column 6. Alternatively the mounting member may be in the form of a spider.

It is considered the invention solves a problem in the coiling of slivers in that it provides relatively much cheaper mechanism of a planetary type. Hitherto planetary type coiling mechanisms have used large peripheral bearings which for high speed coiling have to be of an anti-friction type. Large diameter ball or roller bearings are very expensive and in order to try and reduce the expense and delays in supply, special large bearings have been fabricated with an assembly of wire ring ball races for the ball bearings.

The present invention embodies a feed belt principle and the use of normal standard ball bearings. This is the main reason why this invention will be cheaper and easier to make than other types. With a known flat type coiler, the large bearing has to be of the same diameter as the can. With our invention, the size of bearings to be used are entirely independent of the can size or the eccentricity of the planetary motion. The size is controlled only by normal mechanical features such as loading, constructional design or the like.

Moreover, the bearings of the sliver feed belt rollers may all be mounted on a trap door which so that when it is allowed to open, the whole belt mechanism will be exposed for cleaning purposes. This arrangement need not be used with the illustrated and described construction of a skeleton mounting member (bridge, cross arm or spider) as when the cover 1 is displaced there is easy access to the coiler mechanism.

This invention is confined to so-called depositing type coilers wherein the sliver is drawn, with or without a drafting action, through the mechanism and deposited into a can.
