Claims.
This invention relates to machines for the winding of thread, yarn and other strand-like materials into cones, cops, or similar types of More particularly, the invention relates to an improved means of automatically stopping the action of such winding machine when the cone or other package has reached the desired size. 7
When winding yarn and other strand-like materials into packages, it is desirable that the winding mechanism be provided with a means to automatically stop the winding action when the cone package has reached the desired size. It is further desirable that the means be adjustable so that various size packages may be wound in an automatic manner.
The present invention is particularly directed to winding machines of the type wherein the yarn is wound upon a supporting element, such as a core, mounted upon a rotating spindle, the yarn being traversed longitudinally of the core by a thread guide that bears against the surface of the core, or the wound layers of yarn, and
.which recedes from the spindle as the wound' package increases in size. The thread guide is mounted for reciprocation, in a traverse frame, the latter being pivoted about a central shaft so as to permit this outward movement of the thread guide. The traverse frame is further fitted with a dogging lever adapted to ride in a is in the running position, this hook engages a second hook, fitted to the pivoted, grooved segment of the dogging device. Thus, these'hooks act as a detent means to keep the startinglever in the running position and thus assure the continued operation of the winding machine. Raising the free end of the grooved segment releases the hooks from engagement with each other and permits the starting lever to return to its'original or stop position, thus halting the winding operation.
In the past, this raising of the free end of the segment has been effected by'meansof a member mounted in an adjustable manner along the length of the segment and having a beveled undersurface adapted to be contacted by a portion of the traverse frame. As the package is built up, the traverse frame advances" toward and finally contacts the beveled member mounted upon the segment. This continued motion of the traverse frame against the beveled member serves to gradually lift the segment and release the starting l ver, thusstopping the" winding.
' operation.
groove formed in a segment pivoted upon the chine. It is described in a general way in U. 8.
Patent No. 801,941-to Wardwell. As shown therein, the machine is provided with a starting levermounted on a shaft extending to the back of the machine and adapted to engagethe driving mechanism.- The starting lever is fitted on one side with a braking means adapted to press against the spindle and thus prevent its rotation when the lever is in the stop position. The lever is fitted on the' other side with an arm provided with a hook. When the starting lever This device operates in a fairly satisfactory manner to effect the stopping of the winding operation. However, the traverse frame moves very 1,
slowly and, therefore, it lifts the segment very slowly withthe result that it is difficult to obtain the desired precision in the stopping of the winding operation. and "successive packages vary somewhat in their yarn content.
A still more serious defect of this device rests in the fact that the beveled member serves to gradually retard the continued motion of the traverse frame and thus causes the thread guide to be pressed progressively more tightly against the package being wound. Hence, the yarn at the outside'of the package is wound more tightly and firmly than'the yarn at the inside of the package. Since it is desirable for cone packages to be evenly wound throughout their length, this is quite objectionable.
Itis an object ofthis invention to provide an improved form of device for automatically stopping the action of a windingmachine when the package being wound has reached the desired size.
It is also an object of this invention to provide a'device of this type which may be accurately adjusted to permit the winding of various size packages of yarn or other strand-like material.
It is another object of invention to provide a device of this type that will not cause the cam .9.
outer layers of yarn to be wound 'more tightly than the inner layers, thus assuring the formation of a package that is wound evenly throughout its entire length.
Other objects of the invention will appear hereinafter.
The objects of this invention are accomplished, in general, by positioning a stop on the free end of the pivoted segment of a winding machine which stop will be suddenly contacted by an enlargement on the reciprocating traverse bar of the thread guide as it, together with the traverse frame, moves from the spindle during the winding operation." In accordance with the principles of this invention, a projection on the traverse bar strikes the stop with a forceful blow that serves to instantaneously lift the pivoted segment and thus stop the action of the winding machine. This sudden,-forceful blow is in contrast to the slow and continued pressure exerted against the stop by the movement of the advancing traverse frame of the prior art, and constitutes an important feature of the invention.
The following written description of the inven-. tion will be made more readily understandable when taken in connection with the accompanying illustrations, in which;
Figure 1 is an endelevational view of a winding machine fitted with the device of this invention.
Figure 2 is aside elevational view of the windingmachine shown in Figure 1.
Figure 3 is a side-elevational view of a grooved segment having mounted thereon a stop means for lifting the segment.
Figure 4 is a side elevational view similar to Figure 3 showing another form of stop means.
Figure 5 is an enlarged end elevational view of the stop means shown in Figure 3. 1 Referring to the winding machine illustrated in Figures 1 and 2 of the accompanying drawings, reference numeral l designates the fixed main frame of the machine. At the top of frame I, a
rotating spindle-2 is, joumaled in bearings and adapted to be driven by means of a belt pulley or other suitable mechanism (not shown). The spindleis of usual form and is adapted'to receive a cone or cop tube 3 on which the package 4 is to be wound.
A cam shaft 5 is journaled in. roller bearings in the frame I and extends parallel with the winding spindle 2. The shaft 5 is connected to the Spindle and'is driven therefrom by suitable means, such as belt pulleys or gears not herein shown. The cam shaft 5 carries a helical grooved cam 6 (see Figure 2) of usual type which causes the thread guide I to reciprocate in a manner to be later described.
The thread guide I is mounted on a transverse bar 8. Thetraverse bar 8 is slidably positioned in a groove in an oscillating traverse frame 9.
- The traverse frame 9 comprises a suitable arm II) which is pivoted to rock about the camshaft 5. The overhanging front end of the frame 9 forms a horizontal arm or member II which is slotted A sheet metal back [5 is fastened to the traverse frame 9 and forms a rest or support for the upper portion of the thread guide I. The thread.
guide comprises a metal holder whose lower end is attached to and supported by the outer end of the traverse bar 1 The upper end of the holder is fitted with a c ular head of metal or porcelain the spindle 2 to hold the thread guide I in close o f the dogging device. 'These hooks, when mcontact with the yarn supporting elementor with the layers of wound yarn. A dogging mechanism comprising a grooved segment, or sector, I1 and a lever l8 actsto maintain the position of the traverse frame as it advances from the spindle and thus prevent the thread guide from gouging into the package. The segment is pivoted at l9 on the main frame I of the machine, and the lever I8 is pivoted on the traverse frame 9. The
lever l8 rides in the groove of the segment as shown in Figure 1 The operation of the winding machine is controlled by a starting lever or handle 25, mounted on one end of a rotatable rod 26, the latter being supported, in bearings at thetop of the main frame I. The opposite end of the rod 28 carries means (not shown) for operating a clutch or similar device to controlv the operation of the .spindle and the other parts of the machine driven therefrom. The starting lever is provided on one side with a braking means 21 which is adapted to press against the spindle'and stop the rotation thereof when the lever is in the stop position. The starting lever is provided on the other side thereof with a curved arm 28, the latter is fitted with a hook member 29. When the lever 25 is in the running position, this hook 29 engages a similar hook fitted to the pivoted segment l'l gaged, act as a detent means to hold the starting lever in the running position. v
When the starting lever is in the running position, all that is necessary to stop the winding action is to raise the free end of the pivoted segment I'I so that the hooks 29 and 30 of the detent means will disengage and permit the starting lever to return to the off position." The spring 59 aids in effecting this return of the lever.
As seen most clearly in Figure 2, the outer portion of the traverse bar 8, supporting the thread guide 1, is of heavier construction than the inner portion so that the rod possesses a shoulder 3| midway along its length. Inasmuch as the traverse bar is positioned to slidingly reciprocate in the horizontal arm ll of the traverse frame9,
and grooved longitudinally thereof to provide an extensive bearing for the 'reciprocable traverse bar 9, (see'Figure 3). The traverse bar 8, to
which is fixed the thread guide 1, is thus'mounted.
to slide in a path extending substantially parallel tothe axis of the winding spindle 2. -The-traverse cross head I! which carries a pin or roller H, the latterengaging the helical groove in the traverse bar 9 is connected at its inner end to a slide or the bar swings away from the spindle as the cone or other package is built up in diameter and thus the bar 8 advances, during the winding operation, with the traverse frame 9 toward the free .end of tact with shoulder 3|, or any similar projection, v
on the traverse bar 8 when the latter is oscil-.
.lated, together with the traverse frame 9, to a position underlying the shoulder or' projection.
As shown most clearly inFigures '3 and 4, the
According to the preferred embodiment of the invention, the stop member 32 is of the form shown most clearly in Figure 3. As seen therein, the member 32 is adjustable along the length of the pivoted segment I1, and comprises a U-shaped portion 48 fitted with 2 offset elements, contact element 40 and adjusting element 46, which extend along the lower and upper surfaces of the segment IT. The lower, beveled contact element 40 is adapted to be struck by the shoulder SI of the advancing reciprocating traverse rod 8. The upper adjusting element 46 is fitted with a set screw 42, which serves to position the member 32 firmly at any point along the segment, the point being so chosen that the contact element will be struck by'th'e traverse bar at that moment when the package has been wound to the desired size. The adjusting element 48 is further provided witha second set screw 44 that serves to raise or lowerthe beveled contact element 40 sothat a more accurate adjustment of the member with regard to the traverse rod 8 can be made along the segment. The horizontal arm H as shown in Figure 3 illustrates the slotted and grooved construction of this member serving to support the traverse rod 8.
Referring to Figure 4 of the drawings, the stop member 32 comprises a collar 35 with a single set screw 42 whereby the member may be adjustably positioned at any desired point alon the segment. A projecting contact element 45 is fastened to that portion of the collar 35 which underlies the segment II. This modified form of stop' member differs from the preferred memher in that it is provided with only one set screw. Hence, the finer adjustment made possible by the device of the preferred embodiment cannot be obtained. However, it is possible to obtain a sufficiently fine adjustment to make the device operable and,'in fact, it is possible to more accurately control the stopping of the winding action with this device than with any of the devices of the prior art. This device, like the device of the preferred embodiment, possesses the advantage that the grooved segment of the dogging device is lifted by means of a sharp, forceful blow struck by the rapidly reciprocating traverse bar of the winding machine rather than by a slow continued pressure exerted by the movement of the traverse frame of the windin machine. The member 32 can beformed in one piece or if desired the contact element 40 can be formed as a separate part, and be held in position against the under edge of the segment by the clamping action of a clamping collar or the like.
The present invention has been described above with detailed reference to the cooperative action between the reciprocating traverse bar and a stop member on the free end of the pivoted segment, or sector. The tripping of the segment to release the braking mechanism may be accomplished by any cooperative striking means on the segment and the reciprocating mechanism. For example, a stop member may be positioned on the segment which member will be struck by the reciprocating crosshead I 3 shown in Figure 1. In its broad aspects, this invention contemplates the sudden striking of the segment, to trip the braking mechanism, by the rapidly moving reciprocating mechanism rather than by the slowly moving traverse frame.
This invention provides a method and appa ratus for automatically stopping the action of a winding machine when the package being wound has reached the desired size.
The device provided by this invention results in the formation of a yarn package that is evenly wound throughout. The outer layers of yarn of such a package are not wound more tightly than are the inner layers.
The device provided by this invention acts in a much shorter period of time to stop the action of a winding machine than do other devices known to the art. I
The invention thus provides an inexpensive, easily and accurately adjustable method of stopping the action of a winding machine at the exact moment the package being wound has reached the desired size.
Since it is obvious that many changes and modifications can be made in the above-described details without departing from the nature and spirit of the invention, it is to be understood that the invention is not to be limited to the said details except as set forth in the following claims.
