Patented. 1l, 1941 yUNITED STATES COP WINDING FRAME Wilhelm Reiners, Gladbach-Rheydt, and Gustav Kahlisch, Rheydt, Germany, assignors to W. Schlafhorst & Co., Gladbach-Rheydt, Germany, a corporation of Germany Application February 24, 1936, Serial No'.

In Ge rmany 6Claims.

All the existing cop winding frames4 maybe considered to belong either to one or the other of the following two distinct groups, namely, on the one hand those in which a certainnumber of spindles is interdependent in so far as the cop formation is synchronous for all the spindles of the particular group, or on the other hand the formation of the cop may be for each spindle quite independent of the building-up of the cop on the rest of the spindles.

formation is synchronous for all the spindles of a. particular group has the following advantages over4 the machine of the second group; easier manipulation, a smaller number of manual operations, thereforea higher production per operative and consequently cheaper wages. On the other hand, it has mainly drawbacks leading yto the serious fault of sloughing in the shuttle.

If an end breaks on any of the spindles, the regular formation of the cop will be interfered with and experience has shown that even .if the cop is subsequently filled-up on an auxiliary machine, there is a great danger of sloughing in the 25 shuttle on account of the difference in the density of the cop body.

In thosev machines in which all the yarn guides of the group move simultaneously in the same fashion with regard to their spindles, there will also be a zone of uneven density with the same danger of sloughing. in the shuttle, because in the case of an end having failed the yarn guides will have proceeded for a certain distance before the said end has been knotted and the spindle 35 re-started.

` The object of the present invention is to provide a machine in which the advantages of the methods are combined eliminated.

With this object in view the group system of Aoperation is adopted butwith the novel feature that the several cops are built up independently of each other, the traversing movements for producing the successive layers being independently 45 controlled. Those cops which are not completely wound, due to rupture or failure of yarn, may remain in position in the machine when the other cops are doffed, or they may be returned to the machine after dofilng,"for completionl in the 5o course of the next winding operation. f

The mechanism vprovided enables the winding of each. batch to be started simuitaneously,.but withl each spindle voperating thereafter to build up itsjcopindependently Aof the working of the srv other spindles.

The first group of machines in which the cop and their disadvantages 65,484 March 4, 1935 -Mearis may be provided for collectively dolng -the cops. but with an arrangement enabling incompletely wound cops to be left in position. For this purpose there may be an arrangement whereby the doiling mechanism is disconnected .5 from the spindle mechanism during theA winding operation, and whereby its several units only come into operation, after the Winding, if the respective cops are fully wound.

This device may be amplified by providing lo means whereby the several cop tube carriers of the donningy and doillng device may be put out of operation separately.

Other features of the invention are described hereinafter and specically pointed out in the i5 appended claims. y

Fig. 2Q is a, front elevation of the mechanism actuating thel thread guides of .'a group of spindles.

Referring rst to the construction shown in Figs. 1 to 9, the spindles of the group are all driven by a common shaft I, connected by a yclutch to the motor in the usual way, and provided with a hand wheel19` so lthat'it can be given a number of turns by hand when required. The drive is transmitted to spindles 4 by pairs of bevel, wheels 2, 3. Each spindle 4 is'both rotatable and slidable in its bearings 5, 6. The drive between the gear 2, 3 and the spindle is through a

cone clutch

1, 8. A spring 9 tends to hold the two

clutch members

1, 8 in engagement. The clutch is disengaged by means of a threearmed lever I0, Il, I2. A spring I3 connected at one end to the arm II and at its other end to an arm I4 on the spindle bearing 6 tends to hold the lever I8, il, I2 in its `disengagi'ng position. The lever is, however, prevented from moving to .disengaging position during the winding operation by a double armed lever I5, I5 pivotally connected to the bearing 6. The arm I5 of the lever I5, I6 extends upwards into proximity with a thread detector I3, i9 pivoted at I1 to the bearing arm I4. 'I'his thread detector is held in the position shown in Fig. 1 by the yarn which is being wound. If the yarn breaks or lthe supply becomes exhausted the nose |9 on the detector engages the double armed lever l5, I6 and rotates it so that the clutch lever I0, Il, I2 is released. 'Ihe clutch 1, 8 is consequently disengaged. 'I'he spindle 4 carries at 4its left hand end a ,voke 2| with a bearing 22. This yoke 2| is fixed at its lower part 23 to a rack 24. 'Ihe'latter is guided at 25 and 26 forslidlng movement. A pinion 2 1 engages with the rack, and is rotatable on a shaft 28 common to thev group of spindles, lateral movement of the pinion being prevented by collars 29, 30 (Figs. 1 and 2). The collar 30 is provided on its periphery with a projection 3 I, 'I'he pinion 21 has cast'thereon a ring 32, to the periphery ofwhlch is connected at 34 a chain 33, so that the latter tends under the inuence of a weight 35 to rotate theplnion 21. Cast on the inside of the ring 32 is a projection 36, in the plane of the projection 3| on the colla'r 30. The shaft 28 is mounted on the frame 31 in bearing arms 38, and is rotatable by means of a hand wheel 46. A bracket 4| isxed to the right hand end of the rack 24 and carries a bar 42. On said baris mounted an adjustable striker 43, which is adjusted according to thelength of the cop 44 to be wound. When the cop attains the prescribed length the striker 43 abuts against the lever I5, I6 and thereby rocks the latterrso that the clutch lever III, |I, l2 is released, whereby the

clutch

1, 8 is disengaged.

Fixed to a rod 45 common to the group of spindies are cop cones 46, one for each spindle, said cone when in operative position being coaxial with the spindle 4, as shown in Fig. 1. The cone 46 is held against rotation by

arms

41, 48 and remainsstationary during the winding operation. To enable the rod -45 to be conveniently shifted longitudinally a vlever system |22 is provided at Y one end of the rod, said lever system being connested' to ,the shaft as through the medium of f the nrst constructional example will be readily aV collar .|22a, and the axial movement of shaft vshaft 45.

45 slimited by a collar |22b coacting with a bearing |2311. A shaft 50 is mounted on the frame for rocking movement and carries at each cop position a bracket 5| in which is ixed thev thread guide 52, A yoke 53 embraces the rocking thread guide bracket 5I. Between the latter and the boss of the yoke 53 a spiral spring 54 is arranged on the shaft 58, one end of said spring being connected to the yoke 53 and the other end to the thread guide bracket 5I, the Spring 54 thus forces the thread guide bracket 5I against the The shaft 50 rocks with its thread guides 52 backwards and forwards in accordance with the traverse of the thread. This movement may be produced by means'of a

gear

58, 51, 56, 55, 59, 6I, 68, 50 arranged at the end of the group and driven vby the main shaft I,

Inasmuch as all the thread guides 52 of a group of spindles are operably connected to the shaft 50 they are all moved together to produce the thread guiding movement for the whole group of cops. In the event of thread breakage or the thread supply becoming exhausted, to enable a new thread to be readily threaded into the guide 52 at the corresponding cop unit, notwithstanding the reciprocation of the thread guide, which is frequently rapid, the thread guides 52, as previously mentioned, are not screwed fast to their common lshaft 50, so that owing to the resiliency of the spring 54 one can be prevented from reciprocating with the others, if the handle 63 be held for a moment while the thread is being fed into the thread guide. A drop latch 65 may also be provided adjacent the cop .

cap cones

46, 41, 48, said latch being adapted to be swung back during the winding operation but swung into the position shown in Figs. 1 and 2 for thepurpose of stopping the thread guide 52, so that when the latter swings over to the right to its extreme end position it passes under the h ook of the latch 65 and is held there. On the spindle 4 is a boss 66 the right hand end of which serves as an abutment -for the cop tube or cop to be wound. Said boss has a groove 61 which serves to anchor the commencement of the thread for the new cop,

and it is also provided with twol notched orl roughened ring shaped flanges 68 with an intermediate groove 69. A bracket 10, one' for each cop unit, carrying a thread severing knife 1I is xed on the sliding shaft 45 carrying the cup cones 46. The bracket is so shaped and dimensioned at its upper end 12 carrying the thread severing knife 1| that it is able to enter the annular groove 69 in the spindle boss 66. On one end of the rod 58 is a lever 13 by means of which all the thread guides of a group may be rocked. Above the

spindle clutch

1, 8 there is a rotatable shaft 14 which is common to all the cop'units and is provided at each cop position with a cam 15. A handle 16' may be xed to one end of said rod, as shown in broken lines in Fig. 1. By moving this lever 16 and its shaft 14 with the cams 15 all the cop units can be thrown; into operation,

due to the consequential engagement of their

clutches

1, 8 by the levers I0, I l, |2, the detent lever I5, I6 then holding the parts in this position.

A cop tube trough 18, one for each cop unit, is fixed to the shaft 45. All the troughs 18 appertaining to a group of cops thus slide with the The operation of the apparatus according to understood by reference to Figs, 1 to 9. Qne of the cops 44 (Fig. 1) is almost completed, The

' striker 43 of the rod' 42 is already in engagement with the detent lever I5, I6. Shortly afterwards the clutch lever III, II, I2 becomes disengaged from the shoulder on the detent lever I5, `I6, the spindle is thus thrown out of operation independ-A ently of the other spindles which may possibly not have advanced so far. For instance, as shown in Fig. 2, the centre cop is shown as having re' mained behind due to a defect in the winding.

The shaft 28 is then turned b'y means of hand wheel 40 so that theprojections 3i on the several collars 30 engage with the appurtenant proiections 36 on the rings 32, and as a result all the racks 24 are shifted by their pinions 21 which causes all the spindles to be moved axially so that the cop chases are moved clearof their cup cones 46. By means of the lever 'I3 all the thread guides 52 on the common shaft 50 are swung over lfrornf the position shown in Fig. 1 to the position shown in Fig. 3. The cones 46 (Fig. 4) are moved with the spindle bosses.

Prior to this, all the spindles were clutched to the common drive of the group by the separate device 14, 15,-16 (Fig. 1). As the spindles are pushed out to the position shown in Fig. 3 they are rotated a few times by the simultaneous operation ofthe hand wheel 13 (Fig. 2) of the main drive shaft I, so that the end of the thread 2li winds itself in the form of an extended helix around each cop and is anchored by additional convolutions l (Fig, 5) in the run-on groove 61, this end of the thread passing transversely across the annular groove 63. l

The shaft 45 is shown in Fig. V5 as having been slidden and rocked to such an extent that the brackets 10 thereon with the severing knives 1I have entered the annular groove 69 in the spindle boss, so that first of all the ends of the threads of the bobbins are severed from the starting threads 80 for the/new set of bobbins anchored in the groove 61. At the same time the parts 12 of the lbrackets engage with the groove 63, as shown in Fig. 6. The-spindle head 66 is slidable on the squared part of the spindle 4.

All the spindles are then again C.retracted until the cop with its tube is completely released, when it drops into a collecting container for 'onto a travelling conveyor band. To enable this doillng of the cops from thev body of the spindle to 'be effected by the pushing back of the spindles, the holder 12 of the bracket 10 still engaging vin the groove 63 in the spindle boss holds back the spindle head.

Now the shaft 45 with the cones 46 is pushed along (Fig.u 7) until the troughsY and the empty cop tubes carried thereby are coaxial with the spindles 4 and the brackets 10,' likewise moved, have released the spindle boss 66. Meanwhile (Fig. 8) al1 the spindles remain in retracted posivtion. By operation of the hand wheel 4I! Vthe spindles are now pushed forward into the empty cop tubes and then retracted again. By sliding the shaft 45 back again to starting position the spindles 4 are brought with their cop tubes opposite the cones, and are moved forward to their original operative position (Fig. 9) by means of hand wheel 40. The' thread guides 52 are also moved from their disengaged position shown in Fig. 3 to operative position',

The machine is now ready to operate again, the device 1.4 15, 16 being still in the position in whichall thespindles are clutched to the drive.

The `thread detectors I 8 are also-returned to the position shown in Fig. 1 by thet'ension of Ii threads .23, and the device 14, 15, can bere- 'turned to the position Shown in Fig. l. The building up of the cops commences again,each cop being built up independently of the other.

Constructional example II (Figs. 10520) In this constructional example `for carrying the new'method into` effect the machine is of the so-cvalled spindle-less type wherein :the cops 44 arevclamped in'individual mounts :each consisting of a driving spindle boss 66 and acounter holder I 26. The automatic and independent building movement is effected by the thread guide being moved -for every .new winding layer to the extent of the thickness of .the thread by a feeler 20 wheel |21 on a screw spindle I 28. The traverse movement is transmitted to the thread guides 52a with their screw spindles I 28 for all the spindles of th group by .the common shaft 53a', lwhich is rocked 'by a cam disk 59a (Fig. 20) 25 fixed to a shaft 55a driven from the main shaft I'through a gear not shown in the drawings. The cam 59a acts upon a roller Sia of a lever Sbarockably mountedon shaft 50a and urged by a spring 62a in the direction which holds its -30 opposite end 60h against a lug 13b on lever 13av fixed. to shaft 50a- The shaf't 50a carries loose rock levers |25 which are caused to rock with said shaft by reason of their being spring pressed against a rocking yoke 53a which moves with the shaft. 'I'he rock leven-,H129 transmit their movement through the screw spindles 128 to a lever 130 which is free to rock on the stationary shaft 13|. The lever |30 serves to guide` the' movement of the screw spindle |28 andA it also enables the thread guide movement to be interrupted for av short time, by means of its. handle alt the upper end, so that after an irregularity in the' winding on one of the spindles the :thread may be'readily laid in the guide 52a, due to the rock lever |25 being resiliently connected with rock shaft 56a. l The bobbin drive spindle 4a is 'mounted in the spindle bearings 5a, 6a. The spindle is driven by the common shaft I and the pair of gear wheels 2a, 3a for each cop unit. The wheel 3a is mounted between the bearings 5a, 5a of the spindle support, and is connected to and runs on the same bush'- as one .55 clutchl half 1a, .the other clutch half 8al being slidable by means of the clutchlever Ina, IIa (Figs. 10 and 17). Said lever IIla, IIa is loose on the shaft 14a.yvhich is common to the group.- On the shaft 14a there is also fixed for-each cop unit a cam 16a with a pin lacated'opposite ,the nose Ida on the clutch lever i'a, IIa. To shaft 14a is fixed a hand lever 16a by means of which all 'the cop units of a group are set in motion simul-taneously, said hand lever being rocked'to the right so that the cams 15aA abut l against the nose Iliapf thel clutch lever Ilia.

IIa and cause the spindle clutches to engage. A thread severing member I 24 for'each cop unit is also ilxed to shaft 14a. To the clutch lever lia, IIa is connected a vrod |33 the. other end of which is guided vin -a` bracket |34. Thisrodis provided in proximity to the bracket |34 with a notch and shoulder |35. During the winding operation this shoulder il held` .by a, tension i spring |3a on the lever ||a against a stop on the bracket |34. To throw individual cop units Aout of operation, the rod |33 isy lifted to bring the shoulder |35 clear of the stop on bracket |34. This is also effected automatically when the c'ontrol pin 52h abuts against the nose |33a on the rod |33. The same rod |33V also serves, in the case of thread breakage, to stop the spindle through the medium of the detector |8a by pin |8b, the latter also llifting the rod |33 with its shoulder |35 clear of stop |34.

The thread guides 52a are moved collectively and simultaneously from their limit position to the original position shown in Fig. 16, that is the position at which the thread is anchored, by the following device.

say, to the position at which the thread is anchored. Thereupon all the cop units areV thrown into operative connection with, their driving means by the common gear 14a, 15a, 16a. l

The spindles 4a are then rotatedafew times 5 by rotating the hand wheel on the drive shaft so that the thread for the new set of cops to be wound is secured to the spindle boss in groove 61. The ends of the threads are then severed by the knives |24. 'I'he drop latches |42, k|43 l0 for the fully wound cops all engage with their noses |46 in all the notches |38 in the cop counterheads |26.4 By operating a hand wheel on shaft |54 the supporting means for the latches |42 carried by shaft |48 are moved outwards, l5 and the cop counterheads |26 likewise, so that all the finished cops 44 are released; these copsl may drop onto the endless conveyorvband |69 vin the open container |68, whilst any incompletely wound cops remain in their winding positions due 20 to their coupling with the cop doiling device having remained disengaged. y Y

As shown in Figs. 17 and 18, the bare cop tubes 8| disposed in troughs 18a carried by the arms |18a (Fignl) are swung up -to the skewer- 2b ing position by the cranks |10 through the mef dium of the control rod |10c. Thetrough carriers |18a are pivoted at 11| to their brackets` |12a andare held in upright position byfsprings |12. 'The brackets |12a are mounted on trans- 30 verse bars |10a Iconnected to a guide member |1017. At the upper ends of the trough carriers |18a are inclined abutments |13 which in l tilting upwards lengage with the counterheads |26 of the still lncompletely wound clamped in35 cops and then move away laterally so that no bare tubecan reach the clamping in position at this point. f

IFig. 19 shows means whereby the tube carriens 18a may be manually kept away from the .40 tube feed position by operation of a latch |11 mounted on the common bar |10a for thetube carriers 18a, .there being one of the latter to each cop unit. During the return of the clamping in device |40, |4|, |42,A |43 the bare tubes are 45 again clamped in between the spindle drive heads Then, by means of the hand lever |14 and the fingers 11'5a on the common shaft |4| all the latches |42, |43 are rocked backto the re-set position shown in Fig. 10.

Obviously in lieu of the stationary resilient tube carriers as provided for each cop-unit, the

tube carriers may be arranged on endless conveyor means in known manner, so that the cop tubes are fed from a magazine, for instance at the end of the machine, to the several cop units. Finally, all the thread guides 52a are brought to their starting position for 'the simultaneous commencement ofwinding. The throwing into operati-on of all the cop units simultaneously causes .the thread guides 52a`to swing up from the position shown in Fig. 16 and by the latch |6|, |62 .to strike the upper pin |16, so that the nutv of the wheel |21 engages again with the screw thread on its spindle |28. 65

lThe building'up of each cop independently commencesagain. It will be understood that we do not lim ourselves to the particular constructions shown, since 'they may be modified' Within wide limits 70 Without departing from the spirit of the inven'I tion.
