Our invention relates to a mechanism intended to be used in co-operation with winding frames of all types. Devices have been proposed which save the operator the labor involved inthe supplying ofthe bobbinsto be unwound to the spindle units of the winding frame, the picking-up of the end of the thread on the bobbin, and the removal of the empty bobbin tubes. It is the object of this invention to afford a simple and automatic charging of the conveying means' for the bobbins, such as endless conveying belts, bands, chains or the like with bobbin carriers thereon, the bobbins being in a position on the conveying means best suited for an easy and convenient handling and seizing. This object is obtained by the bobbins being taken, from a storage receptacle by an automatic device at any place on the frame, advantageously at one or both front ends, and put onto the bobbincarriers of the conveying means. The bobbins are then withdrawn manually by the operator ac. cording to requirement from the constantly running conveying means at the respective place of the winding frame and put onto the unwinding spindle of the spindle unit at this place.
Thus, the operator himself no. longer needs tol carry the bobbin to the respective place; on the contrary, the bobbins are in a convenient posi tion ready to be seized and the thread end of the bobbin tobe pieced can be made ready beforehand by a junior worker who lls the storage receptacle on the front end of the machine.
We further provide on the above-mentioned 'device for automatically charging the bobbin carriers of the conveying means a further device, the object of which is to cripple the automatic charging device by a bobbin which has not been withdraw from its carrier by the operator and passes anew through the device, so that the bobbin remains on its carrier, and unnecessary operations are avoided.
Finally, our new bobbin feeding mechanism may be so designed that the conveying means, that is, the` conveying chain, belt or the like is further employedto remove the empty bobbin tubes, for which purpose hitherto a conveyor had to be provided.
In order that our invention may be more readily understood, some embodiments of the same are diagrammatically illustrated by way of Aexample in the accompanying drawings.
Fig. 1 is a side' elevation of a winding frame, with the winding mechanism removed, showing our improved bobbin feeding mechanism.
special MarchlZ, 1931, Serial No. 522,036 L l Germany March 21, 1930 Fig. 3 is'aside elevation of the automatic bobbinfeeding mechanism, with the side of the housing removed,
Figs. 4 and 5 are similar views showing the mechanism in vtwo dierent positions,
Fig. 2 is'a plan view of the device shown inv Es PATENT OFFICE f Fig. is a cross section on the line 6-6 of Fig. 3,
Fig. 'Lis a detail sectional view of the conveyor chain, showing an individual bobbin peg traveling on its guide, and
Fig. 8 is a similar view of showing the bobbin peg in horizontal position. The drawings show the frame of a winding machinercomprising uprights 2 and 4 and horlzontal bars 6. Mounted upon brackets 8 and l0 are longitudinal rods l2 carrying supply holders 14, to which bobbins 5 are to be transferred from a conveyor mechanism now to be described.
In this embodiment of the invention the conveyor'which carries the, bobbins past the supply holders is formed by a chain 8l which runs round the entire machine. In lieu of a chain any other suitable -conveying means may. be used,'such as a belt, band or the like. The chain 81 is guided on the four corners of the machine by sprocket wheels 12a, 12b, 12c12d and carries bobbin carriers or pins 83. These pins 83 are pivotally mounted on the chain 81 in the manner illustrated in Figures 'l and 8. As will be seen, the pin 83 is guided by a projection 83.1: bearing on a horizontal guide y fixed on the machine frame whereby also the chain 8 1 itself is protected from sinking down on its path along the machine, which path is more or less long according to the number of the spindles to be supplied. As long as vthe bobbin pins 83 remain supported by their projections 83a: on the guides u, the bobbins are in a vertical or at least upwardly' inclined position in which they lcan easily be seized and withdrawn. Now, the guide 1i'v is interrupted at the places denoted by Aand B, Figure 2, between which an automatic feeding device 91 is arranged. Consequently the pins 83 when leaving the guide y rock into a co-opera'tion with the automatic feeding device 91.
The conveyor is driven in the following manner: 18 denotes the driving motor, Figures 1 and 2, and 19 is the driving shaft coupled therewith and carrying the driving pulley 20 of the winding vframe itself. 21 denotes a worm gear which the conveyor chain horizontal position, which is best suited for the y lever transmits the rotary motion of shaft 19 to a transverse shaft 22 and therewith to a further worm gear 23. On a vertical shaft 24 driven by this gear is mounted the sprocket wheel 12o of the chain conveyor 81. The automatic bobbin feeding device 91 is actuated by a cam disc 25 fast to the shaft of the sprocket wheel 12b, which cam disc possesses two cams and acts upon an elbow lever 27, 28 marked in dotted lines in Figure 2 and fulcrumed at 26. A roller 29 of this is held constantly against a cam disc 25 by the action of a spring 30. Lever 27, 28 further carries a pin 31 which engages with clearance a bobbin slide 32. When lever 27, 28 is rocked by the cams of cam disc 25, slide 32 which carries the bobbin to be put on a carrier 83, is rapidly shifted to the right (Fig. 10) and slowly to the left. The instant a bobbin pin 83 is in axial alinement with slide 32, the latter with the bobbin thereon is pushed by lever 27, 28 toward this pin 83, whereby the bobbin is put onto the pin 83, whereupon the slide returns to initial position. 'Ihe supply of the bobbins to the feeder takes place by means of an endless conveyor which, as shown in Figs. to 14, is in the form of a chain conveyor 33. The chain conveyor 33 runs on sprocket wheels 34, 35 and is fitted with cross-bars 47 for supporting the bobbins.
In Figure 3 the feeding device is illustrated at that instant of operation when a pin 83 of the conveyor 8l, with a bobbin 5 which had been automatically placed thereon, has just left the device in the direction of the arrow, while the next pin 83 is approaching. 3'6 is a feeler rigid on a rockable shaft 37 which has further mounted on it a gear wheel 38 and a loose ratchet wheel 39. The teeth of ratchet wheel 39 are formed as ordinary gear teeth. Wheel 38 carries a lateral pin 40 which projects toward ratchet wheel 39 by about the width of the space existing between the two wheels. On shaft 37 is further loosely mounted Aa lever 41 which carries a pawl 42 cocperable with ratchet wheel 39. The latter is further in mesh with a gear wheel 43 fixed on the shaft of lsprocket wheel 35. The gear wheel 38 in turn engages a wheel 44 fixed on a shaft 45 which further has rigid with it a feeler 46.
In Figure 4 is shown the arrangement of the parts immediately previous the feed of the next pin 83 with a bobbin 5. The described mechav nism operates as follows:
As soon as a pin 83 of the conveyor 81 touches the feeler 36, the latter is rocked into the position illustrated in Figure 4 whereby also shaft 37 with gear wheel 38 is rocked. 'I'he latter actuates lever 41 through pin 40 so that pawl42 advances the loose ratchetwheel 39x By this rotation of wheel 39 wheel 43 which is in mesh therewith is also turned, thereby actuating the conveyor chain 33. 'I'he latter may be tted with cross bars 47 securing a correct position and feed motion of the bobbins thereon. Now when the conveyor 33 is advanced stepwise by the bobbin pin 83 through the intermediary of the mechanism described, always the foremost bobbin 5 drops over a partition 48 onto the slide 32. The instant the respective pin 83 is in axial alinement with the bobbin 5 resting on slide 32, Figure 4, lever 27, 28 is pushed forward by leaving one of the two cams of the constantly lrevolving cam disc 25 whereby the bobbin 5 is shifted onto the pin 83. After this movement slide 32 is returned to ready position by the back of the respective cam.
Figure 5 illustrates in what manner the feeding device is crippled in the event that a,bobbin 5 has notl been withdrawn from its pin 83 and thus arrives again at the feeding device. In this case the bobbin 5 strikes the feeler 46 and lifts it, whereby the wheel 44 mounted on the same shaft is rocked, which wheel turns with higher speed the smaller wheel 38 mounted on shaft 37. By this turning motion the feeler .36 which is also fixed on shaft 37, is rocked out of the path of the arriving bobbin 5 so that the conveyor 33 is not advanced and thus no new bobbin is fed to slide 32, while the bobbin that has been put onto itsV pin 83 during the preceding revolution can freely pass the feeding device.
49 is a flap hinged to the cabinet of the device the object of which flap is to protect the bobbin resting on the slide 32 from falling down therefrom laterally. As illustrated in Figure 3 the flap 49 gives way when lifted by a bobbin put on a pin 83 so that the pins 83 with their bobbins can freely leave the feeding device.
'I'he automatic feeding device for the bobbin carriers of a conveyor which runs round the entire machine can be applied without difficulty also to machines which have a separateconveyor on either side.' In this case each of these two conveyors is equipped with an individual feeding device.
Furthermore, our invention can be applied to every type of Winding frame, and is not conned tb machines of the type described, 'which shows merely an example of application.
What we claim as our invention is:-
1. The combination with an endless conveyor for carrying full bobbins to the several stations of a winding machine, said conveyor having bobbincarriers thereon adapted to hold the bobbins throughout the circuit of the conveyor until forcibly removed, of a chargingdevice driven in unison with ysaid conveyor and adapted to mount bobbins on said carriers, and means adapted to be deflected by a full bobbin approaching said charging device upon any of said carriers for disabling said charging device until said full bobbin passes. l
2. A device as described in claim 1, wherein said charging device comprises a bobbin magazine, a movableslide, means for feeding bobbins singly from said magazine to said slide, and means driven in unison with said conveyor for moving said slide as said carriers come opposite the same to transfer bobbins to said carriers.
3. A device as described in claim 1, wherein said charging device comprises a bobbin magazine, means for transferring bobbins from said magazine to said carrier, means for feeding bobbins singly from said magazine to said transferring means, moans for driving said conveyor, transferring means, and feeding means in unison.
