There are some cop spooling machines in which the winding on all the spindles or at any rate on a group of spindles is started and stopped simultaneously, in the entire machine; or the group of spindles is stopped in order to remove the cops and put on new tubes. done by hand, and necessitates a relatively long stoppage of the spindles, with consequentreduction of efiiciency as regards the output or the machine. In connection with ring spinning, certain devices have been-contrived for the purpose of taking off the full spools or cops and putting on the tubes in groups, the full spools being lifted by means of forks fitted with pins, or 'by grippers. The disadvantage of these arrangements is that in some respects they interfere with the operation of the machine, as they. are more or less in the way of the operator, even if during normal working they are removed from close proximity to the spindles. This renders it almost wholly impracticable to apply them to spooling machines, owing to the greater strain on the thread, which causes far more breakages of thread and other troubles in winding, which must be rectified by the operator during the working of the spindles.

The importance of simultaneous removal, of

finished cops followed by a simultaneous mechan- Gil ' 7 been proposed to use a. conveyor band which can be raised andlowered to lift the empty twist rollers into the plane of the retractable spooling spindles (which can also be drawn) to take up the released full rolls of twist and to place the empty ones between the spindles and the centres. A device of this kind, owing to the trouble'and expense of fitting it up, cannot be used in cop spooling machines, and also obstructs the view of the process of spooling.

The object of our invention is to make it DO sible to effect simultaneous winding of cops and exchange of cops for empty tubes, in the whole bank of spindles, or any group of spindles, however large, without incurring the disadvantages described above. For this purpose we arrange the cop handling unit outside the area of arrival of the tread, and we provide for relative movement of this unit and the spindles. With the I spindles stationary, the cop handling unit may be This has hitherto been movable both transversely of the axis of the spindles and also in the direction of the spindle axis, or it may move only in the axial direction. In the case of axially movable spindles the-cop handling unit may be movable transversely of the spindles, and inthe case of cop spools which are inserted between the spindles and a back centre, the unit is movable transversely of the spools and also axially.

Several examples of apparatus according to the invention are shown in the annexed drawings.

Figs. 1 to lO'illustrate diagrammatically that form of the device in which the spindles are stationary and the unit X, which serves any desired number of spindles, is movable both transversely of the spindle axis and also in the direction of the spindles.

In Figs. 1 and 2, I is the winding spindle, F the thread, 2 the friction wheel seated thereon, which is driven by friction disc 3 mounted on shaft 4. The shaft 4 isdriven in the usual way. 5 are the thread guides, which are mounted on a bar 6 in common with all the other thread guides of one side of the machine, or for a group of spindles. The bar 5 is actuated by racks l and a pinion 8, the pinion being fixed to a shaft 9. On the same shaft 9 there is fixed a disc II], with a chain I I engaging a portion thereof. The chain II at its upper end also engages with a disc I2, around a portion of the latter. The disc I2 is fixed to a shaft l3. The latter is mounted on a lever I5 pivoted at I4. The lever I5 carries a pin with a roller [6. This roller I6 is moved by a heart-shaped cam I! on a shaft I8. The shaft I8 is driven by a gear wheel I9 and gear wheels 20 and 2i. The gear wheel 2i is mounted on the driving shaft 4. The gear wheel I9 is freely rotatable on its shaft I8, but is restrained from lateral displacement and can be coupled with a collar 22, which is slidable on the shaft I8, to which it is splined. While this coupling 22 is out of engagement the shaft I8 with its heart cam I1, and consequently the entire mechanism II, I0, 9, 8, l and 6 is stopped, although the top spindles I can continue to rotate. The feed movement of the thread guide 5 takes place in the following way:

On the shaft I3 there is fixed a worm wheel 24, with which engages a worm 25 having its bearing shaft on the lever I5. To the same shaft is fixed a ratchet wheel 26, which is rotated stepwise by a double armed lever 21 and pawl 28, backward rotation being prevented by pawl 29. On each stroke of the lever I5 the lower arm of the lever 21 strikes an adjustable screw 30, so that the swing of the lever can be regulated by adjustment of the screw, and this regulates the angle through which the ratchet wheel is rotated. The chain II is wound on to the disc l2 and off the disc Ill, and at the same time the shaft 9 with gear wheels 8 is rotated and the racks I with the thread guides 5 are shifted. In order to keep the chain II taut there is a disc 3| fixed to the shaft 9, with a chain 32 carrying weight 33 attached to its rim. The weight 33 not only keeps the chain ll taut but also effects the backward movement of the thread guide when pawls 28 and 29 are disengaged and ratchet wheel 26 is rotated backward by its handle 26a.

The cop handling unit, which is designated as a whole by the reference character X in the various figures, is shown in Figures 3 to 10.

The unit X may form a single rigid frame for a plurality of spindles, the longitudinal walls 340. and 3 b of the said frame being connected by transverse walls 35.' The longitudinal walls are further connected with each other by troughs 36 in the manner of a grating. In these troughs the empty cop tubes 31 are placed ready for slipping onto the spindles. Centrally between two troughs 3G, notches 38 are provided at the upper edge of the longitudinal wall 34?), which, for the purposes of stripping off the full cops'Bla from their spindles. I engage each bare spindle behind the foot of the cop. The unit X is arranged below the plane of the spindle axes. It rests on rollers 39a and 39?), which are mounted on levers 48a and 40b. The levers Ma and 40b rotate about shafts Ala and E-lb. To the shaft lla is fixeda hand lever 42 (Fig. 2). By means of this lever and rods 33, chains, or the like, the unit X can be moved from the position of rest shown in Fig. 3 to the position shown in Figs. 5-10. The shafts lla and ill) are mounted in the machine frame Y at Ma and 44b (Fig. 1) and are in the form of toothed racks towards the interior of the machine.

The shaft 4Ia is formed as a toothed shaft at its rear (Fig. 5) and engages with a pinion 45 mounted on a shaft 46. This shaft can be rotated. by a hand wheel 41 (Figs. 1 and 2), and in this way the body X can be shifted not only vertically but also horizontally, this latter movement being for the purpose of shifting it into the position shown in Figs. 7 and 8, from the position shown in Figs. 5 and 6, after it has received the cops or bobbin tubes. In order to be able to shift the body X lengthwise of the machine it slides with its transverse walls 35 on pins 58a and 48b, for which purpose the transverse walls have a slot 49, of angular form, the vertical part of which'serves for the upward movement of the body X, while the horizontal part allows of the forward movement. The longitudinal movement of the part X on the pins 480 and 48b, is limited by suitable stops 50a and 50b. The longitudinal movement of the part X on the rollers 39a and 3% may be effected by hand or by lever mechanism not shown.

The manner of operation is as follows:

In Figs. 3 and 4 the cops 31a on the group of spindles have just been completed. The end thread F is wound around the cop in a steep spiral by a rapid return movement of the thread 4 guide in the manner previously described; on the bare spindle I a few turns have been run at la, so that the thread is held firmly at this point and the cop is ready for stripping off. The part X is in its position of rest beneath the spindle. In the trough 36, a cop tube 31, ready for slipping on to the spindle, is indicated by broken lines.

The operator then raises the unit X vertically upward by the aid of the lever 42, so that the notches 38 in the rear longitudinal wall 34b engage the spindles l behind the cops.

As shown in Figs. 7 and 8 the part X has already been shifted forward out of proximity to the spindles by means of the handwheel 41, pinion 45, and the rack portion of shaft dla (Figs. 1 and 2); during this operation all the cops 31a have been stripped off and have dropped into the box 52 at the bottom of the unit X, from which they can be taken out by hand.

After the cop has been drawn off the spindle, the part X is moved to the extent of about half the pitch of the spindles, see Figs. 8'and 9, so that the empty cop tubes 3'! are in line with the spindles.

"n In Figs. 9 and 10 the part X is moved by wheel iii)" 42, returned to its lower position. The thread guides are now, by means of the ratchet wheel or hand wheel 26 (Figs. 1 and 2), brought back to the starting position for the new winding operation, and the rotation of the spindles I is started at the same time by throwing the driving belt I60 by means of belt shifter I6I from the idle pulley I62 to the fixed pulley I63, whereby the thread fixed upon part Ia of the spindle winds around the bare cop tube to begin the winding operation.

- When the cops are fully wound the process above described is repeated.

Figs. 11 to 16 illustrate an example in which the spindles are axially movable. Consequently the unit need not be movable in the direction of the spindle axis, its movement transversely of the spindles being suflicient.

, The cop handling unit does not in this case differ in its essential parts from the other ex- 99 in the trough 52 is shown in Figs. 19 and 20.

The relatively long part of the shaft I03 between the gearings I04 is toothed.

To the trough 52 two holders I05 are fixed, which serve as bearings for a shaft I06. On this shaft, between the holders I05, there is a roller 99a, which serves to drive conveyor 99. At one end of the shaft I06 there is a pinion I00, which is in constant mesh with the toothed part of the shaft I03, and can move along that part together with the trough 52 and the conveyor 99. From this it is clear that the endless conveyor can be set in motion in any position of the device X. The movement for the conveyor with the full cops takes place during the working of the machine.

The drive of the spindles can in this case be by cords or bands 85 extending between driving pill-- leys 3c and the driven pulleys 2c. The pulleys 2c are fixed to sleeves 2d having square bores in which spindles I can slide longitudinally without being permitted to turn relatively to the sleeve. The spindles furthermore are rotatably mounted in the angle bar carried by the racks c. The movement to and fro of the-spindles l, is effected by a pinion 45c meshing with a rack 460.

When the cops are ready, the cop handling unit is lifted by means of handle lever 42 and the arms 40a, 4012 from the position .shown in Fig. 11 to that shown in Fig. 12, and subsequently the spindles I are retracted, so that the spools 31a are released by the action of stripping faces 30 and fall into the trough 52. When this has been done the cop handling unit is moved to the extent of half the distance between two spindles, so that a tube is placed in front of each spindle, as shown by broken lines in Figs. 11 and 13. The spindles are then moved forward from the position shown in Fig. 12 to that shown in Fig. 13, and pick up the tubes, whereupon the cop handling unit is moved back to the position shown in Fig. 14, by the manipulation of handle lever 42. In this case one longitudinal wall 34b of the part X may 5 be provided, at the point where its notches 38 engage over the spindles, with knives 84, the object of which is to cut the thread before the cops are stripped off. This cutting is effected by turning the spindle I, as this conveys the thread tom wards the cutting edge of the knife 84.

In Figs. 15 and 16 this part of the device is shown to a larger scale.

Theexample shown in Figs. 17 to 20 deals with the case in which the device X is movable only 15 in the direction of the spindle axis. The container 52 with the conveyor 99 and the axial shift by rack Ma and pinion 45 are the same as in the embodiments shown in Figs. 1-16. The part X, however, carries a table 90, with recesses for 20 receiving the tubes 31, which rest against a rail 90a. On the bottom face of the table there are bars 93 (in this example one for each spindle) with longitudinal slots 93b for engaging over guides 9 I, 92 fixed to the table, so as to allow movement in the direction of the spindle axis. On the end facing the spindle each bar has a part 93a engaging behind the spool, and a pin 94 behind which a hook lever 96 engages. All the hook levers 96 of those spindle groups which belong together, or all the spindles on one side of the machine, are mounted on a shaft 95, which can be rotated through a definite angle by a hand lever 91. When the winding of the spool 31a is completed, and after release of all the bars 93 35 by the movement of the lever 91, the rack Ma. and the pinion move the part X with the table 90 to the left, in, which movement all the bars 93 participate. They strip the spools 310. from their spindles and allow them to fall into the container 52, as shown in Fig. 19. The part X with the table 90 and the container 52 is then moved back. In this movement the bars 93 take part until they strike against the holders of the spindles. The table-90 with the container 52 moves together with the rack 4Ia, under the action of the pinion 45, farther to the right, into the position shown in Fig. 20, whereby the tubes 31 are pushed on to the spindles. In this position the lever 91 is moved back so that the hook levers 96 engage behind the pins 94 (Figs. 1'7 and 18). When this has taken place the part X, with the containers 52, moves back into the position shown in Fig. 17, so that the process of spooling can be resumed. Instead of providing a bar 93 for each spindle there may be only two bars for one group of spindles, the two bars being connected at 38 by a cross bar common to the group of spindles, the cross bar having for each spindle a recess 38 for stripping off the finished spool.

In the example shown in Figs. 17 to 20 there is, it is true, some reduction of accessibility to the thread, but this is not of any importance, having regard to the-compact construction of the cop handling device; in any case, however, it is the simplest form of construction of the cop handling device X.

Figs. 21 and 22 show in somewhat more detailed form the actuating mechanism for the cop handling device. The cranks 40a and 40b 70 are pivoted on their shafts Ma, 4"), and are coupled with each other, for example by tie rods The cranks are provided with rollers 39a and 76 39b, by which they engage under the longitudinal walls 34a, 34b. The longitudinal movement of the cop handling device X is limited by stops 5011 on bar 4811, for which the guide slot 49 (see Figs. 1, 3, 5, etc.,) is provided in the front wall 35a.

In Fig. 21 the mechanism is in its lower position at which time the spindles execute the winding operation. By rotating the hand lever 42 and giving a quarter turn of the crank arms 40a and 40b in the direction of the arrow (1, the part X is raised to the position shown in broken dash lines, and at the same time it is moved to the extent of half the pitch of the spindles, so that the notches 38 engage the spindles behind the cop spools. This unitary arrangement of the lever mechanism causes both a vertical and a lengthwise movement of the part X to be produced by a single actuation of the lever mechanism.

By a partial return movement of the lever 42 the part X is first moved back lengthwise, so that the previously distributed tubes are disposed in front of the spindles in preparation for their mounting upon the spindles in the manner described above.

Fig. 22 shows how, instead of the cranks 40a, 40b, cams 98 may be used, having exactly the same effect. In this case the cams on the shaft llb are moved by those on the shaft Ma, through the medium of a rod 43.

Owing to the fact that the troughs 52 and also the conveyor 99, perform at least the movement in the direction of the spindles with the part X, the trough and the conveyor are not only always held in the right position to receive the cops, but both parts, during'the working of the machine, are pushed inwards under the spindles. If the trough and the conveyor'were stationary, as hitherto, then the trough and the conveyor would have to be in a position which would considerably widen the machine.

As already stated with reference to Figs. 11-14, the trough 52 for receiving the spools may be provided at its bottom with a conveyor by which the spools are conveyed to a collector. In order, however, that the conveyance of the spools to the collector and their distribution in the latter should take place in a proper and regular way, the conveyor, consisting for example of an endless band 99, is provided as shown in Figs. 23-25 with cross bars I09, between which the cops are placed. The movement of the conveyor band is, as already mentioned, produced by rollers 99a, one of which is driven by any suitable means. For conveying the spools to the collector H, the device X may be provided with a feed pipe or feed channel H0, as shown in Figs. 23 and 24. The collector is moved to and fro mechanically under the channel H0, by means-of rack gear Illa andacam disc lllb.

Fig. 25 shows another example of this device, according to which the container Ill is stationary while the feed channel H0 is provided with a hopper and is swung to and fro above the container III, by the agency of the cam disc Illb,
