SHlGEMATSU TAKH'A BY y W attorney United States Patent 3,141,286 ROTARY SPIWDLE TIP DEVICE Shigematsu Takita, Takarazuka, Hyogo, Japan, assignor to Nihon Shaft Co., Ltd, Hyogo, Japan Filed Feb. 6, 1962, Ser. No. 171,468 Claims priority, application Japan May 31, 1961 11 Claims. (CI. 57-73) This invention relates to a rotary device for spindles of spinning or twisting machines, and, more particularly, to an assembly which performs twisting in cooperation with the traveler and which performs twisting as its principal role as a result of being located far nearer to the feed rollers than in the case of conventional or prior art mechanisms. This is significant in the situation where particularly long rolls are being wound so that there is an extra long vertical travel of the ring.
It is the principal object of the invention to provide a device of the nature stated wherein the twisting disc is rotatably mounted at the top end of the spindle, coaxially and independently thereof.
Another object of the invention is to provide a construction as aforesaid, wherein the thread guide is positioned closely adjacent the top center of the twisting disc and which effectively controls and reduces ballooning of the thread.
A still further object is to provide a twisting device which is removably mounted upon the spindle and in which the twisting disc is journaled for independent rotation coaxially of and relatively to the spindle.
Another object is to provide a twisting device for a spinning machine wherein practically all twisting is effected by the disc.
Yet another object is to provide a twisting device of the nature aforesaid which is easily removed for repair or replacement, protected against excessive wear, safe in use, and which produces thread of fine, smooth and uniform texture.
Other objects and advantages of my invention will become apparent to those skilled in the art, after a study of the following detailed description, in connection with the accompanying drawing.
In the drawing:
FIGURE 1 is a vertical axial cross section showing a first form of the invention;
FIGURES 2, 3 and 4 are corresponding sections of second, third and fourth forms, respectively;
FIGURE 5 is a plan view of the twisting disc;
FIGURE 6 is a diagram showing the relation between the thread, twisting disc, and thread guide, as the ring rail rises;
FIGURE 7 is a side elevation of a portion of the friction sleeve in the species of FIGURE 2; and
FIGURE 8 is an end view of the friction sleeve of FIGURE 7.
Referring in detail to FIGURE 1 of the drawing, 2 identifies a winding shell or holder shown as of wood and having a central axial bore fitting spindle 1. The upper end of the shell is counterbored as at 18 to receive a cylindrical casing 8 having its lower end seated upon an annular shoulder formed by first and second portions of the counterbore, of different diameters, and its upper end flush with the corresponding end of shell 2.
Twisting disc 3 has notches 4 in its periphery, equiangularly spaced as shown upon FIG. 5, and an integral depending hub 5 by which it is keyed or otherwise fixed to the upper end of stub shaft 10. Shaft is journaled for rotation in shell 2, by a bearing assembly which includes a bearing sleeve 9 fitting within casing 8 and having its lower end closed by a cap 9a threaded to engage internal threads of the sleeve. The upper end of sleeve 9 is fitted with a gland 9b through which the shaft extends. Upper and lower antifriction bearings 13, 13:: are separated by a cylindrical spacer or spool 1317. Upper and lower thrust plates 13c and 13d are interposed respectively between upper gland 9b and bearing 13, and lower cap 9a and bearing 13a. The construction is such that disc 3 rotates in its bearings with very little friction and with only a slight amount of end or axial play, as indicated by the axial separation between gland 9b and upper thrust plate 13c.
A magnet 11 is fixed in the lower end of the counterbore in shell 2, symmetrically of the axis thereof, and acts to prevent axial vibration of the shaft 10 and the parts mounting it for rotation, and to yieldingly hold the assembly of bearings, sleeve, shaft and disc against axial removal from shell 2. A thread guide 6 is mounted, by means not shown, for vertical or axial adjustment, from a position as shown upon FIG. 1, wherein the vertical separation between guide 6 and the disc 3 is one centimeter or less, to an upper position. Referring to FIGURE 6, the position 6 corresponds to that shown in FIG. 1. In this position the pass of thread from guide 6 to the flyer, makes a relatively large angle with respect to the axis of the spindle. In position 6' the guide has been moved upwardly so that the angle 64-17 is essentially the same as 6'417'.
In FIG. 2, shell 2a has a counterbore 18 in its upper end, to receive a bearing holder or support 12. In order to provide a snug frictional interengagement between the shell and holder, a metal cylinder 14 is attached to the end of the holder. As shown in FIGS. 2 and 7, this cylinder has equally-spaced longitudinal slots 14a in its peripheral wall and the intervening portions between slots are bowed slightly outwardly to frictionally engage the walls of bore 18 so that the holder and shell rotate as a unit with the spindle. Twisting disc 3a has a diameter less than disc 3 but has its periphery similarly notched as at 4:1. Cylindrical bearing sleeve 9c removably fits an axial bore in the upper end of the bearing holder 12, and is axially apertured to receive shaft 19a fixed with disc 3a and journaled for rotation in the sleeve by antifriction upper and lower bearings 13 and 13a, held in place, respectively, by thrust plate Be and race 13f. A seal 13g fits the upper end of the bore in holder 12 and protects the bearings. Added protection is afforded by the upper circular end of holder 12 interfitting with a channel in the under side of disc 3a.
In the species shown at FIGURE 3, the disc: 3b is essentially like 3a, and its shaft 10b is similarly journaled in antifriction bearings 13 in sleeve which removably fits a bore in the holder 12a. Holder 12a has a tapered bore 712 in its lower end fitting down over the upper end of spindle 1. Tube 2b fits the cylindrical surface of holder 12:: and is releasably held against axial displacement by a number of buttons is mounted in respective recesses in the holder for limited movement radially thereof, each being urged outwardly by a spring 15. When the tube is properly positioned axially of the holder as shown, buttons 16 snap into recesses in the inner walls of the holder to releasably maintain the shell in proper winding position.
The species of FIGURE 4 is essentially like that shown in FIG. 3, so that it is sufficient to identify disc 30, notches 4b, bearing sleeve 9d, shaft 10b, holder 12b and sleeve 20.
In operation, when spindle 1 starts to rotate, if no thread is positioned in a notch of disc 3, 3a, etc., the latter also attains a speed of rotation nearly that of the spindle and shell 2, 2a, etc. When a thread from the feed rollers to thread guide 6 is held by the guide, positioned closely adjacent disc 3, the thread is twisted rapidly over its length extending back to the feed rollers, without,
however, breaking, because the disc is decelerated relatively to the spindle and winding shell and winding of the thread upon the shell begins.
Careful inspection by stroboscope flashing synchronous- 1y withrotation of the parts shows that the thread seetions-passing from disc 3 to the traveler, not shown, and thence to the winding shell, cop, or bobbin, are nearly coplanar in a plane radial of the axis of the spindle. Hence twisting is performed almost entirely by the disc 3 and the thread sections mentioned pass as a unitary element from the disc to the shell, so that the traveler acts largely to regulate or to smooth out irregular twisting. The result is a reduction in the load on the traveler and ring, so that the traveler may be made light in weight, with a corresponding reduction in centrifugal forces and resulting wear upon the ring.
Furthermore, because the twisting of the thread is performed almost exclusively by the twisting disc 3, 311, etc., as compared with prior art machines wherein the twisting is performed by the traveler alone, I have found that the thread tension is less in the portions mentioned so that Weak spots are eliminated and the thread produced is strong and uniform in composition. Since thread guide 6 is located closely against disc 3, centrifugal forces due to ballooning cannot throw thethread out of its notch 4 and is efficiently controlled.
Furthermore, since the thread is not tensioned until the disc 3, 3a, etc., starts to rotate, and since this rotation is delayed for a period by the fact that the disc is journaled for rotation on and about the axis of the spindle, there is time for the operator to effect tying.
Another advantage is that the assembly comprising the disc, its shaft, bearings and casing can be lifted off, even while the machine is in operation, to thus greatly facilitate removal of waste thread or replacement with another disc assembly. Of course, in the case of FIGS. 2, 3 and 4, the assembly referred to includes holder 12, 12a or 12b, as the case may be.
