Definitions

  • ABSTRACT An assembly of thread-dispensing units, mounted on a common spindle bank, include each a spindle with a rotating throwoff disk beneath a magnetically arrested tubular spool holder through which the thread of one or more spools is guided downwardly for passage through the disk hub whence it emerges generally radially to form a balloon enveloping the spool or spools.
  • My present invention relates to a spool holder for twisting, spinning or similar machines wherein a number of threaddispensing units are mounted on a common spindle bank in which a like number of upright spindles are journaled for concurrent rotation.
  • each spindle with a so-called throwoff or ejector disk which rotates with the spindle about the axis of the latter and in turn carries a tubular spool support held against rotation by magnetic detents.
  • One or more threads drawn from a corresponding number of spools on this support pass downwardly through the tube, usually by way of the upwardly projecting hollow spindle, into a hub of the throwoff disk from which they exit via a lateral orifice at the underside of the disk, preparatorily to being guided upwardly past the disk rim to a point above the support for delivery to a windup bobbin or the like.
  • the general object of my invention is to provide an improved spool holder for the aforedescribed purpose which eliminates these disadvantages.
  • a more specific object is to provide a compact assembly for a group of thread-dispensing units in which the individual thread balloons are effectively separated from one another with relatively close spacing yet without physical contact between the revolving thread and a surrounding enclosure.
  • this housing configuration there is also provided a convenient location for accommodating a set of outer magnets serving to hold the spool support against rotation.
  • the outer housing surface is prismatic, as is desirable for manufacturing and assembling purposes, the bottom portion of its wall is appreciably enlarged at the corners of the prismatic contour so that the magnets can be readily imbedded in the wall at these corners.
  • the magnets are advantageously located just above the level of the throwoff disk so that their counterparts on the spool support may be disposed below the spool body within the contour of the disk.
  • the spool support may include a tubular central post surrounded by a cylindrical sleeve or cup to form therewith an annular chamber, the base of this sleeve being substantially coextensive with the disk and receiving the inner magnets confronting the stationary outer magnets. It is to be understood that only one magnetic element of any confronting pair need be permanently magnetized and that the other element could be a soft-iron armature. Also, electromagnets could be used in lieu of permanent magnets as is well known per se.
  • FIG. 1A is a cross-sectional elevation, taken on the line lA-IA of FIG. 2A, of a thread-dispensing unit embodying the invention
  • FIG. IB is a view similar to FIG. 1A, taken on the line IB IB of FIG. 2B and showing a modification;
  • FIG. 2A is a cross-sectional view taken on the line IIA-IIA of FIG. 1A, showing the same unit together with portions of adjacent units;
  • FIG. 2B is a view similar to FIG. 2A taken on the line lIB- IIB ofFIG. 11B;
  • FIG. 3 is an isometric view of a series of units of the type shown in FIGS. IA and 2A.
  • FIGS. IA and 2A I have illustrated part of a spindle bank 10, also shown in FIG. 3, supporting a spindle 114 which carries a pulley 116 to be driven by a transmission belt from a power shaft not shown.
  • Spindle I4 is rigid with a throwoff disk 42 having a hub 40 provided with a lateral exit orifice 38 from which a thread 48 is continuously discharged.
  • Thread 48 is composed from two filaments 30, 32 drawn off a pair of spools 26, 28 which are removably seated on a tubular post 17 of a spool holder generally designated I8; the spool holder also comprises a cylindrical cup I9 which coaxially surrounds the post 17 and defines therewith an annular spool chamber 21, the base 23 of cup 119 being substantially of the same diameter as the disk 42 from which it is separated by a small clearance as it rests on an upward extension 41 of hub 40.
  • a narrow annular gap 20 is formed between the disk 42 and the base 23, on the one hand, and a surrounding housing 58, on the other hand, which is fixedly supported on spindle bank by a pedestal Ill.
  • Housing 58 has an inner peripheral wall which in its bottom portion 68 is generally frustoconical up to a level 60 (FIG. 3) and is then faired, between levels 60 and 62, into a prismatic upper portion 76 of square outline.
  • the thread 48 rises in the form of a balloon 44 swirling about the cup 18 without touching either that cup or the housing.
  • the thread then passes through an eye 46 in line with the axis of the hollow spindle 14 whose tip 34 receives the filaments 30, 32 from spools 28, 26 to lead them axially through the post 17 into the hub whence they emerge at orifice 38.
  • detent magnets 22, 24 holds the spool support 18 against rotary entrainment by the disk 42.
  • the inner magnets 22 are imbedded in the cup bottom 23 whereas the outer magnets 24 are lodged in the thickened wall portions of housing 58 at the corners of its rectangular outline. (Although the housings of adjacent units are shown merged into an integral structure, this outline will be apparent from imaginary parting lines 81, 32 shown in FIGS. 2A and 2B.)
  • the magnet pairs 22, 24 come to lie at the diagonals of the square as best seen in FIG. 2A.
  • FIGS. 18 and 2B which show a modified cup 19 in an otherwise similar unit
  • magnets 22', 24' in the shape of vertical disks replace the horizontally disposed bar magnets 22, 24 of FIGS. IA and 2A.
  • the exposed surfaces of the magnets should be curved so as to be flush with the adjacent surfaces of their respective carriers.
  • each housing 58 is raised above the other sides to form a parting wall between adjoining units. Also, as best seen in FIG. 3, each housing is split at one side of the spindle bank llill (generally the operators side) to form a vertical slit 74 giving access to the orifice 33 (in an aligned position of spindle 114) to facilitate the positioning of the thread within the space between spool support 18 and housing 58.
  • the entire housing structure, generally designated 72 in FIG. 3, can be molded or cast from synthetic resin or light metal.
  • a thread-spinning machine with a plurality of dispensing units mounted in a row in a common spindle bank comprisan integral elongate structure supported on said bank, said structure being subdivided into longitudinally adjoining portions of substantially square outline forming respective housings for said units;
  • each housing for drawing thread from a spool on said support and directing said thread downwardly therethrough along the axis thereof, said disk having a hollow hub accessible from the interior of the associated spindle for receiving said thread and a lateral orifice for the discharge of said thread along the underside of the disk;
  • each unit includes two pairs of said magnetic retaining elements and two confronting pairs of said cooperating elements disposed at the diagonals of said substantially square outline.
  • peripheral wall is of circular outline in the region of said disk and define therewith said annular gap.
  • peripheral wall is faired into a prismatic shape above the level of said disk and said retaining elements.
  • a machine as defined in claim 4 wherein a side of the prismatic peripheral wall between adjoining units is raised above the remainder of said housing and beyond the top of said support, the housings of two adjacent units being separated by said raised side.
  • each of said cooperating magnetic elements is disposed within the contour of the respective disk.
  • said support includes a cup with a base of substantially the diameter of said disk and a central post defining therewith an annular spool chamber, said cooperating elements being mounted in said base.
