4 Claims.
This invention relates to spool ejecting and sizing mechanism designed for incorporation in Winding and for re-winding machines such as are commonly used in the throwing departments of textile mills, particularly in winding machines wherein the spools are fioatingly supported and driven through peripheral contact with continually revolving driving rotors to draw the yarns or threads from supply packages in the form of larger spools, cones or skein reels.
In connection with mechanism of the kind referred to, we aim to make it possible through provision of simple, inexpensive and reliable means such as hereinafter disclosed, to effect automatic displacement of the spools upon becoming fully wound or filled, from contact with the driving rotors to a retracted idle position where they are supported against further rotation and from whence they can be readily removed by the machine attendants and quickly re placed with fresh or empty ones while the machines keep running.
Other objects and attendant advantages will appear from the following detailed description of the attached drawings, wherein Fig. 1 is a fragmentary view in front elevation, showing a portion of a winding or redrawing machine conveniently embodying the spool ejecting and sizing mechanism of our invention.
Fig. 2 is a view in sectional elevation taken as indicated by the angled arrows II-II in Fig. 1.
Figs. 3 and 4 are fragmentary views like Fig. .2. showing how the mechanism operates to eject and stop the spool at the completion of a windmg.
Fig. 5 is a fragmentary view corresponding to Fig. 1 showing the position in the machine of a fully wound spool after dofling.
Fig. 6 is a view in side elevation looking as indicated by the angled arrows VIVI in Fig. 5.
Fig. '7 is a view similar to Fig. 5 showing a modification.
With more detailed reference to these illustrations, the numeral 1 comprehensively designates the framework of the winding machine which provides plural pairs of vertically-spaced open bearing notches such as indicated at 8 and 9 in Fig. 1 adapted to receive the diametrically reduced ends of spindles like the one shown at III for a spool II. The yarn Y to be wound upon the spool II is drawn from a supply package I2 supported on a shelf I3 at the rear of the machine and enroute to the spool, is diverted over fixed transversely-extending guide rods I4 and I5 for passage between tensioning disks I6 mounted on a stationary rail H at the top of the framework I. After emerging from between the tensiOning disks I6 over the guide rod I5, the yarn passes through a notch la in a projection I9 on a traverse 20 which is reciprocated endwise as required to evenly distribute the yarn along the core of the spool II. The means for actuating the traverse may be of any well known construction and for this reason has been omitted from the drawings. The spool II is rotated in the direction of the arrow of Fig. 2, through frictional gravitational contact of a roller collar 2| on the spool spindle adjacent one end of the latter with the periphery of a drive wheel 22 affixed to a constantly revolving transverse shaft 23 which is rotative in suitable bearings afforded by the machine framework 1.
The ejecting and sizing mechanism with which the present invention is more particularly concerned, comprises a cam disk element 26 which is pivoted oif center on a stud 21 on the horizontal arm of an angular bracket 28 (Fig. 2) clamped, with capacity. for both up and down and lateral adjustment, to a pair of stationary rods 29, 30 supported crosswise of the machine framework 1. From Fig. 1 it will be noted that the cam disk 26 is disposed adjacent the drive end of the spool I I, and that it has two tread portions 26a and 26b which are eccentric to each other and to the pivot stud 21, and which are adapted to coact respectively with the winding on the spool and with the contiguous end head lid of said spool to effect dofi-lng in a manner presently explained.
Normally during the winding, the disk 26 hangs free on its sustaining stud as shown in Figs. 1 and 2, it treads 26a and 26b free of contact with the spool head I Ia and the yarn accumulation thereon. Upon accumulation of the yarn on the spool to a predetermined diameter as exemplified in Fig. 3, it will contact the tread 26a of the disc 26 and as a consequence be rotated clockwise as indicated by the dotted arrow thereon, and eventually, during such rotation thereof, its tread 26b will be brought into engagement with the periphery of the spool head Ila whereby, at the end of a, half revolution as in Fig. 4 the spool will be upwardly displaced at one end and take the angular position in which it is shown in Fig. 6 with the roller collar raised out of contact with the drive wheel and with the corresponding spindle end above the notch bearing 8. Thereupon, by the rotative momentum of the spool I0 and incidental draw of the yarn Y, the lifted end of the spindle II will be pulled inward to rest upon the ledge 3| alongside the notch of 3 bearing 8, and there be stopped from further rotation for convenience of ready removal by the machine attendant and replacement by a fresh or empty one.
As an alternative and as shown in Fig. 7, a second cam element 26' exactly like the cam element 26 may, if desired, be employed to lift theother end of the spool II in the same way as above described, with attendant dislodgment of the spindle ends from both of the notched bearings 8 and 9.
Having thus described our invention, we claim:
1. Spool ejecting and sizing mechanism for a yarn winding or a rewinding machine wherein the spool is floatingly supported in frictional contact with a driving rotor, said mechanism comprising a disk eccentrically mounted for free rotation about a fixed axis beneath the spool and having two treads in eccentric relation, one for initially contacting the yarn accumulation on the spool and the other for subsequently contacting the periphery of a head on the spool in effecting the ejection; and means constructed and arranged to support the spool after it is filled and displaced for convenience of ready removal from the machine.
2. Spool ejecting and sizing mechanism for a yarn winding or a rewinding machine in which the spool is floatingly supported in frictional contact with a driving rotor, said mechanism comprising a. spindle for the spool, an open notched bearing for one end of the spindle, a disk eccentrically mounted for free rotation about a fixed axis and beneath the spool and provided with two treads'in eccentric relation, one for initially contacting the yarn accumulation on the spool and the other for subsequently contacting the periphery of a head on the spool adjacent the aforesaid spindle end; and a ledge adjacent the notched bearing for supporting the aforesaid end of' the spindle upon displacement of the spool by the disk after the spool is filled.
3. Spool ejecting and sizing mechanism for a yarn winding or a rewinding machine in which the spool is floatingly supported in frictional contact with a driving rotor, said mechanism com prising a pair of disks each eccentrically mounted independently for free rotation about fixed axes beneath the spool and having two treads, one for initially contacting the yarn accumula-' tion on the spool and the other for subsequently contacting the periphery of a head on the spool in effecting the displacement; and means constructed and arranged to support the spool after.
it is filled and displaced for convenience of ready removal from the machine.
4. Spool ejecting and sizing mechanism for a yarn winding or a rewinding machine in which the spool is floatingly supported in frictional contact with a driving rotor, said mechanism comprising a spindle for the spool; open notched bearings for the opposite ends of the spindle; a pair of disks eccentrically mounted independently for free rotation about fixed axes, each having two treads in eccentric relation, one for initially contacting the yarn accumulation on the spool and the other for subsequently contacting a head on the spool; and ledges adjacent the open bearings by which the spindle ends are received and supported upon filling and displacement of the spool.
