AUTOMATIC WINDER Filed July 13. 1940 3 Sheets-Sheet 3 INVENTOR MMR f ATTORNE s Patented Sept. 14, 1948l I OFFICE AUTOMATIC WINDR Walter Schweiter, Horgen, Switzerland, assignor to Maschinenfabrik Schwelter A. G., a corporation oi' Switzerland Application July 13, 1940, Serial No. 345,255 In Switzerland August 25, 1939 8 Claims. (Cl. 242-19) 1 The invention is an improvement in automatic winders which are machines that take empty bobbins from a magazine and wind them with yarn and then discharge the wound bobbin. When the yarn is severed, in order to release the wound bobbin from the machine, the cut end still remaining in the machine has to be attached to the next-arriving empty bobbin to start the winding on it, and this `is done by mechanism which lays such yarn across the face of the winding head so that it will be pinched against the end or butt of the fresh bobbin when the winding head advances to engage and rotate the bobbin. The length oi yarn required for this purpose remains as a tail on-the discharged bobbin and has to be torn off by hand before the bobbin goes intouse.
The purpose of this invention is to remove such tail in the windlng`machine automatically and prior to the discharge of the bobbin so that the latter is immediately ready for use. Such removal is accomplished according to this invention vwhile the bobbin is still in its winding position and by means of a suitable parting tool which severs the yarn between the point where it is pinched against or otherwise attached to the bobbin and the point where it becomes part` of the wound mass on the bobbin. There is no limitation herein to any particular style of bobbin or core and all kinds are included in the term bobbin.
In the accompanying drawings, which are to be taken as illustrative only of the invention:
Fig. 1 represents a side elevation of the bobbin in winding position and its associated winding mechanism having the preferred form of the invention applied to it;
Fig. 2 is asimilar view with parts removed and at a later stage in the winding cycle;
Fig. 3 is a sectional detail illustrating the relaion of the yarn to the bobbin butt, above referred Figs. 4 and 5 are detail cross sections of the mechanism, showing thepreferred form of the invention;
Fig. 6 is a plan view of certain parts of the control gear.
Qnly so much oi an automatic Winder is shown as is necessary to exhibit the relation of the present invention to this class of machines. i
Referring'to Figs. 1 and 2, it will be understood that empty bobbins marked I are transferred one by one from a hopper, not shown, to the winding position in which they are successively clamped between the winding head 2 and the rotary, spring-yielding center 3 of a fixed tail stock 4. In
the Winder taken for illustration, the winding head 2 is automatically advanced and retracted to accomplish this function, but the clamping could also be done by the advance of the tail stock 4 so f lfar as the principle of this invention is concerned.
.- The transferrer is indicated at in Fig. 5 and will be understood to withdraw automatically when the winding head has taken charge of the: bobbin,
The yarn is guided to the rotating bobbin by means of a traveling yarn guide 6, later referred to, and when the winding head is retracted at the end of the winding stage the full bobbin falls butt first into the discharge chute 1. While it is momentarily held in the chute, the yarn still connected to it is engaged by two lingers, one
below the winding head marked 8 in Fig. 2, and
one above the head marked 9 in the same figure.
nism contained in or mounted on the gear 'case I I, the construction of which isalready known to the art. The tail-stock 4 is mounted on the end of a frame rod I2 rigidly projecting from this gear case as its support; and the carriage I3 in which the yarn guide 6 is held slides on this rod, being advanced along it slowly by means of a chain I4 driven by a ratchet-operated sprocket wheel I5 and against the tension of a return spring I6. The yarn guide carriage initiates the Y bobbin-changing cycle by tripping ya suitable member, not shown, when it reaches the end of v the bobbin. This releases the ratchet-sprocket wheel, permitting the spring I6 to return the carriage to its place of beginning, ready to start the winding on a fresh bobbin.
The yarn guide shown is designed to lay the yarn on the bobbin with a progressive criss-cross .pattern as customary for filling bobbins. but this i is a matter of choice. Such guide is carried as an arm on the upper end` of a short rock shaft Il journalled in the carriage I3 and provided with a` crank finger I8 at its lower end which travels along a rail I9 carried on a rock shaft 20, as the',
carriage advances. The oscillation ofthe rock". shaft oscillates the yarn guide against as,sr 1irtlg, not shown, thereby giving a wig-was mtiQIithe guide-eye as the carriage moves along, all of,
n also according to design now standard,
gxil bfrrgilng no part oi this invention; other yarn-guiding mechanism is well known and could bstltuted. be'Ill'ile operation of the winding head 2 as described is accomplished by journalling its spindle in a sleeve bearing, slidably mounted in the gear box, and moved back and forth by a link connec- ;tion 2| with a cam and cam-lever 22 inside the the yarn carriage has returned to the start position. The head is then retracted to release the bobbin as above explained and the winding head is therefore not rotating when the tail of the yarn is laid against it as above described,
The parting device of this invention is mounted in any convenient way to operate on that section or length of yarn that crosses over the bobbin butt, or the end to which the yarn is pinched; see Fig. 3. It may consist of any suitable yarn-severing member herein called a knife and marked 30, and the yarn is severed by encountering it, as it is carried around by the bobbins rotation. It is rendered active in the present case by being advanced to its operating position where the yarn will strike it, and this is preferably done by pivoting it, as at 3 I, to an adjustable bracket 32 secured to the face of the gear box. It can thus be swung from an operating position close to the bobbin as shown in Fig. 4 to a remote position indicated in Fig. 5, where it will not be likely to interfere with the arrival of empty bobbins. A spring Sia normally urges it to one of its positions, preferably its remote position and a set-screw 33, in the bracket 32, serves as a lnal limit to its motion toward the bobbin.
When the core or bobbin is supplied with reenforcement rings asindicated at 34, each of these forms a peripheral shoulder over which the yarn extends and by means of which a short section of the yarn, between or at the sides of the rings is held clear of the bobbin surface and the working position of the knife is gauged so that its hook-shaped end enters the crevice or groove between adjacent rings. or at the side of one oi them, hooking into the yarn since this makes for a more reliable severance. but within the invention it is only important that the knife approach the bobbin close enough to make the cut without injurious contact with it. The use of a corrugated or cross-grooved butt is therefore not indispensable although it is preferred. The adjustment provided in the bracket 32 is in the direction of the bobbin axis and enables the knife Position to be registered accurately with the cross groove of the bobbin, but at the same time the knife arm is susceptible of some lateral movement by reason of its thinness and flexibility so that in the event of an odd-sized or diierently contoured bobbin it may be deflected by the rib or ringinto the adjacent groove. Such contact of knifewith ring, if it should occur, is not injurious to the bobbin. The knife thus has movement toward the bobbin and is capable of limited motion in the direction of the bobbins axis.
To put the knife in its active position, any
means working in phase with the bobbin-supply can obviously be used and in the present case such means is a linger-shaped cam 35 fastened to the yarn guide carriage in such position as to engage the top of the knife and depress it toward the bobbin shortly after the carriage starts its outward traverse and while the guide eye is laying the initial turns on the lowerpart of the bobbin. The nger rides over the back of the knife and thus depresses it to the required extent, determined by its adjustment and limited by the set screw 33. On the return of the carriage. the knife is similarly and momentarily depressed but this action is not of consequence since the yarn has already been cut.
On the discharge of the bobbin, the severed piece or tail either falls out of the way or is drawn out of the way by a suction scavenger hood. indicated at 33 in Fig. 1. Such removal may be facilitated, with or without the use of an air hood. by giving the winding head a short rotation in its retracted position sulcient to throw the tail off in the event it should tend to stick to it. Such throwing-off effect is produced by providing a notch 31 at the appropriate point in cam 23 which will close the clutch 23 for a few revolutions, while the winding head is retracted, then bringing it to rest again in time to be advanced against the incoming bobbin. Thus the winding head is clutched to the drive shaft twice during each cycle, once for rotating the bobbin and again for clearing it of any adhering yarn.
