17 Claims. (01. 242-355) 1 This invention relates to machines for winding packages of yarn, thread, etc., and is concerned more particularly with a winding machine containing novel means for winding the strand material upon a headless bobbin or tube and so manipulating the thread guide that the package produced has tapered or conical ends. By reason of the inclusion of the new features, the machine of the invention is simpler in construction than prior machines for the same purpose and it is less expensive to build and easier to operate and maintain in working condition.

The new machine includes conventional means for rotating the bobbin or tube and such means may be of either of the well known types for driving the bobbin or tube at a constant surface speed or at a constant number of revolutions per minute, as may be desired. A frame is pivotally mounted on a fixed support adjacent the bobbin and is provided with means maintained in engagement with the package building up on the bobbin by means which urge the frame toward the bobbin. The, frame thus swings at right angles to the axis of the bobbin as the package increases in diameter. A traverse bar is mounted on the support independently of the frame and extends lengthwise of the bobbin, and the bar is reciprocated endwise during the operation of the machine. frame and is operatively connected to the traverse bar so as to reciprocate therewith. At each end of its stroke, the guide is rocked by means carried by the frame, and as the frame is swung during the building up of the package, the action of the rocking means is varied so that the thread guide is given the proper motion to produce the tapered ended package.

For a better understanding of the invention, reference may be made to the accompanying I drawings, in which Fig. 1 is a plan view of a multiple winding machine of the invention;

Fig. 2 is a front elevational view of the machine of Fig. 1;

Fig. 3 is a sectional view through the machine on the line 3-3 of Fig. 4;

Fig. 4 is a sectional view on the line 44 of Fig. 5 is a sectional view on the line 5-5 of Fig. 4; and

Fig. 6 is a plan view of the thread guide show ing the course of the yarn therethrough.

In the drawings, a drum winding machine embodying the invention is illustrated, and this machine includes a supporting structure comprising vertical frame members It and longitudinal members ll of any suitable construction. A shaft I! mounted in bearings carried by the structure extends lengthwise of the latter and is provided at intervals with conventional cork driving rolls It. The shaft carries a gear l4 at one end, which meshes with a gear IS on a shaft 16 provided with a driving pulley l1, although shaft l2 may be driven in any other convenient manner. At its opposite end, shaft l2 carries a driving pulley it. around which is trained a belt I 9. The belt passes around idlers 20 and about a pulley 2| on a shaft 22, which drives a shaft 23 through reduction gearing generally designated 24. Shaft 23 carries a cam 25.

A mandrel 26 is mounted for rotation opposite each cork roll l3, and for this purpose, a number of brackets are attached to the supporting structure to extend upwardly therefrom. The end brackets 21a lie beyond the end cork rolls, and the intermediate brackets 21b lie onposite the faces between adjacent cork rolls. Each end bracket 21a is provided with a U-shaped channel 28, which is open laterally and extends downwardly in a direction away from the adjacent' cork roll. At its lower end, the channel is closed by a wall 29, and upwardly from the wall,

A thread guide is mounted on the the top of the channel is cut away, as at 30, to permit the introduction of the gudgeon 3| of the mandrel. Each intermediate bracket 21b is formed with a pair of channels similar to channels 28 and placed back to back so that each intermediate bracket supports the gudgeons of adjacent mandrels. The mandrels are of a size to permit the bobbin or tubes 32 to be fitted snugly thereover and may be provided with conventional means for securing the bobbins or tubes in place thereon.

A frame is pivotally attached to the longitudinal member ll of the supporting structure opposite each mandrel and cork roll combination to swing about an axis substantially parallel with the axis of shaft l2. Each such frame comprises a plate 33 provided at its lower corners with brackets 34, which are pivotally attached at 34a to brackets 35 secured to the longitudinal frame member ll. At its outer end, the plate is provided with brackets 36 projecting toward the cork roll, and between these brackets 36 is mounted a roller 31, which is adapted to bear against the package being wound on the bobbin or tube on the mandrel. Roller 31 is spaced from the adand one of the brackets 36 is secured to plate 33 by means of bolts, so that the bracket and roller 31 can be removed for cleaning purposes. A thread guiding rod 38 is mounted in brackets 39 on the outer face of plate 33.

A traverse bar 40 is mounted on top of the longitudinal member H of the supporting structure in suitable guides (not shown) to extend parallel to shaft I2 and the bar is provided at one end with a roller 4| engaging the surface of cam 25. As the cam is rotated, the bar is reciprocated endwise, and it is kept in constant contact with the surface of the cam in any convenient manner, as by means of a spring 42 attached to the bar and bearing against a part of the supporting structure. Opposite each cork roll, a pair of spaced brackets 43 are attached to the outer face of the traverse bar, and an arm 44 is pivotally mounted in each pair of brackets. For this purpose, the brackets are connected together near the bar by a bolt 45, and the arm is formed at its end with a loop encircling a pin 44a having coned ends which are detachably received in openings near the ends of the brackets. The axis about which arm 44 swings is coincident with the axis about which frame plate 33 swings, so that as the frame swings outwardly, arm 44 may swing with it and continue to lie parallel thereto.

A lever 46 is pivoted at 41 on arm 44 well below the top thereof. The lever is of bell crank form with legs of unequal length, and its shorter generally horizontal leg is provided with a roller 48 on its rear face. The longer upright leg of lever 46 carries a thread guide 49, which may conveniently be formed of a length of wire looped upon itself and held in place by straddling a stud 50 on the outer face of the upright leg of lever 45. The thread guide is further held in place by passing through a slot in flange 46a at the upper end of lever 45. The two branches of the thread guide are in alignment above the end of lever 45 and pass between roller 31 and plate 33, and the branches flare outwardly at their upper ends, as indicated at A guide plate 52 is pivotally mounted at 53 on the inner face of plate 33 of the frame, and the guide plate has a longitudinal slot 54, in which travels roller 48 on lever 45. A cam plate 55 attached to one of the brackets 35, in which plate 33 is mounted, extends outwardly at right angles to the plane of plate 33 and through an opening 55 in plate 33. This cam is engaged by one end of guide plate 52, and the guide plate is held in contact with the top surface of the cam by a spring 51 attached at one end to the frame plate 33 and bearing at its free end in a slot in the upper edge of-that portion of guide plate 52 encircling the pivot stud 53.

The active surface of cam 55, against which the end of guide plate 52 bears, is a curve of uniformly increasing radius developed from a point on a vertical line through the axis on which the frame swings. Near its outer end, the cam is formed with a notch 59 in which the end of guide plate 52 may drop when the frame is swung far enough outwardly away from the package on the mandrel. When the guide plate drops into the notch, the frame is held in place free of the package, so that the latter can be moved downwardly and the mandrel gudgeons 3| can be moved outwardly through openings to channels 28. In order that the guide plate may be released from the notch, it is provided near one end with a pin 52a which extends through a slot 33a in plate 33. By raising the pin, the end of guide plate 52 may be released from the notch to permit the frame to be moved back toward the package.

Each frame is urged to swing in a clockwise direction, as viewed in Fig. 3, by means of a spring 59 attached at one end to plate 33 and at its other end to a fixed part of the supporting structure of the machine. The action of the spring causes roller 31 to contact with the package being wound at all times. As the frame is swung away from the package during the growth of the latter, the contact of the thread guide with the outer surface of the roller causes arm 44 and lever 49 to swing with the frame. Since the axis on which arm 44 swings is coincident with the axis on which plate 33 swings, arm 44 and lever 46 are thus maintained in their original relation to plate 33 as the top of the frame swings outwardly.

At the start of the operation of the new winding machine, each frame is swung away from its mandrel by the operator, until its guide plate 52 drops into the notch in its cam. The mandrel can then be removed from its mounting and a tube slipped over it. The mandrel is then put back in its mountin and guide plate 52 released from the notch in the cam to permit the frame to be swung upwardly by its spring 59, until roller 31 on the frame engages the surface of the tube on the mandrel. The spring 59 causes the frame to force the tube into contact with the cork roll I3, as indicated in Fig. 3. The thread 60 from the supply is then passed upwardly over the guide bar 38, between the two branches of the thread guide 49, and over roller 31 to the tube on the mandrel. When the machine is started, the traverse bar is reciprocated by cam 25, and it moves each arm 44, each lever 46, and each thread guide 49 with it. As each lever 46 moves along the rear face of a plate 33, the engagement of roller 48 on the lever in the slot in guide 54 causes a backward rocking of lever 46 at each end of each stroke of the traverse bar. In such backward rocking of lever 45, its upper end moves backwardly, that is, in a direction opposite to that in which the lever as a whole is moving relative to its plate 33. The extent of such rocking movement of the levers depends on the inclination of the slots 54 of the respective guides 52, which are in turn controlled by their cams 55. As the packages build up, the axis of each mandrel moves away from its cork roll, and, similarly, its frame is moved outwardly. This causes its guide 52 to move along the surface of the related cam 55, and the inclination of the guide varies, under the control of the cam, to increase the backward rocking of the thread guide as it approaches each end of its stroke. The result of this action is to cause a progressive shortening of the traverse of each thread guide lengthwise of its mandrel, and each package is, accordingly, formed with tapered or coned ends.

In prior winding machines of the same general construction, it has been the practice to mount the traverse bar on the frame, so that the bar moves with the frame as the latter is swung outwardly during the building up of the package. In the new machine, the traverse bar is mounted on the support, rather than on the rocking frame, and this simplifies the construction and also makes it easier to maintain the machine in proper working condition. By forming lever 46 with a relatively short horizontal leg and a longer vertical leg, a slight change in the inclination of guide 52 produces a greater change in the traverse of the thread guide relative to the package. The active surface of cam 55 is, accordingly, relatively flat, so that guide 52 may readily move along it. The formation of the notch in the cam, into which guide 52 may be received to lock the frame in inoperative position, makes it easy for the operator to remove full packages and place empty tubes in position. Also, when the frame is in its outermost position, the means for actuating the thread guide are fully exposed so that they can be kept clean and in proper order.

In the machine illustrated, the package is rotated by contact with the cork roll l3, but, if desired, the tube on which the package is to be wound may be mounted on a spindle in accordance with the usual practice. When this type of drive is used, no changes in the frame or the thread guide actuating mechanism are necessary.

In a single winding machine of the new construction, the traverse bar 40 is relatively short, but in a multiple machine, the bar extends the full length of the machine so as to actuate the thread guides each of the packages being wound. Adjacent each package, the bar is provided with brackets 43 supporting an arm 44 for the frame of each package. The packages are, accordingly, all wound simultaneously and are of uniform formation.

By forming the arm 44 of suflicient length to extend well beyond the pivot point 41 of lever 46 and causing the thread guide 49 to pass between plate 33 and roller 31, the lever 46 is constantly maintained with its stud 48 in the slot in guide 52 without the use of additional means for the purpose. As the frame swings outwardly, roller 31 bearing on the thread guide causes the latter to move with it, and lever 46 and arm 44 are constantly maintained parallel to the plane of frame 33.

The new winding machine can be used for either twisting or redraw purposes, depending on whether the supply is rotated during the winding operation or remains stationary. In prior machines for such purposes, it has been the common practice to employ bobbins with heads and, when such bobbins are used, difliculties are encountered, since the traverse of the threadguide must be such as to lay the thread on the barrel of the bobbin to fill the space between the heads exactly. If the adjustment of the machine is not precise, therefore, perfect packages will not be produced. In the use of the new machine, it is not necessary to employ bobbins with heads, since the packages have tapered or coned ends which make them stable. such a package can be wound without the exact adjustment of the machine above mentioned and the new machine, therefore, requires less attention than prior machines winding on bobbins with heads.
