(Cl. 242-25) The present invention relates to winding apparatus. More particularly, the present invention relates to `a wire coiling apparatus adapted to coil wire or the like on a spool which may either be stationary or rotate during winding of the wire thereon.

Wire coiling devices are known which are equipped with stationary spools, as well as winding devices which have a plurality of rotatable spools driven by a common shaft. Winding apparatus equipped with stationary spools are of particular advantage in winding wire which can be wound at great speed. However, in the case of wire, such as steel Wire or thick wire, which is not adapted for coiling on a stationary spool, it is necessary to use a machine having a rotating spool. It has been necessary, therefore, to utlize heretofore two different complete machines in order to coil the diiferent types of wire.

The present invention is designed to overcome the above disadvantages and in carrying out the present invention an apparatus is provided wherein the spool is made stationary by means of a planetary gear arrangement and includes a supplementary gear arrangement to produce rotation of the spool if desired. This .supplementary gear arrangement also provides for a desired direction of rotation as Well as the desired speed of rotation of the spool. Finally, the coiling device of the present invention is so constructed that it maybe easily put into and out of operation, and for this purpose a coupling device is provided on the shaft of the coiling apparatus.

It is an object, therefore, of the present invention to provide a coiling device which is adapted for coiling various types of wire.

It is another object of the present invention to provide a wire coiling device which may alternatively utilize a stationary or a rotating spool on which the wire is to be wound.

It is a further object of the present invention to provide a multiple wire coiling apparatus of the above type for simultaneously coiling a plurality of wires.

Other objects and advantages will become apparent from the following description and the appended claims.

The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific arent embodiments when read in connection with the accom-- panying drawings, in which:

Fig. l is a side elevational view partly in section of a coiling apparatus constructed in accordance with the present invention;

Fig. 2 is an end view of the multiple coiling apparatus' I according to the present invention;

Fig. 3 is a plan view of the apparatus shown in Fig. 2; Fig. 4 is a detailed View of a guide roller mounting incorporated in the device shown in Fig. 1;

operating the coupling device of the apparatus shown inv Fig. 1.

p Referring now to the drawings, and particularly to Fig. l, there is shown a closed unitary housing 1 which serves as a carrier support for several independent coil winding machines and as shown in Fig. 3, housing 1 supports eight individual coil winding devices. The` operation of all of the coil winding machines is carried out by means of a common shaft 2 journalled in housing 1, the shaft 2 adapted to be driven in any suitable manner. To this end, there is provided steel worms 3 arranged on shaft 2 spaced at particular distances. As shown in Fig. 1, steel worm 3 is arranged in engagement with a worm gear 4, which is loosely mounted on coil winding shaft 5 of the coil winding machine, While shafts is rotatably mounted in housing 1 on integrally cast bearings 6 and 7.

A winding disc 8 is xedly secured to shaft 5 for rotation therewith, disc 8 having at its outer periphery a link member 9 which carries a rotatable guide roller 10 and is turnable about a pivot axis, as shown in the solid and dotted lines of Fig. 1. Shaft 5 is provided with an axially extending channel 12 passing therethrough, and the Wire to be wound on spool 15 is guided into channel 12 by means of guide rollers 13 and 14 arranged at one end of shaft 5, the wire being conducted out. of channel 12 by means of guide roller 11 which is mounted adjacent and extends into channel 12. The mounting of guide roller 11 on shaft 5 is shown in greater detail in Fig. 4.

The wire thus conducted through channel 12 and around guide roller 1t? is continuously wound during the rotation of disc 8 on spool 15, which remains stationary during such rotation of disc 8 by virtue of a planetary gear arrangement shown in Fig. 1. This gear arrangement includes a spur gear 16 which is iixedly mounted on bearing 7. Engaging spur gear 16 is a pinion 17 which together withpinion 1S is mounted on a common shaft 19, pinion 18 adapted to engage a spur gear 2t) which is mounted for axial movement on the hub 21 of spool 15. The pinions 17 and 18 have the same pitch and the same diameter, as do the larger spur gears 1.6 and 20, respectively. Shaft 19 is mounted on support 29 integral with disc 8. Hub 21 is loosely mounted on coiling shaft 5 and is thereby rotatable relative to shaft 5.

It will be seen that as shaft 5' and disc 8 rotate together, the gear arrangement above described provides for spool 15 to remain stationary when pinion 18 engages spur gear 20.

Coiling of the Wire can also be carried out with the same apparatus on spool 15 while the latter spool rotates by means of the planetary auxiliary gear arrangement also shown in Fig. 1. This auxiliary gear arrangement includes an additional pinion 22 mounted on shaft 19, pinion 22 being of smaller diameter than pinions 17 and 18 and being adapted to engage spur gear 23 which is fixedly mounted relative to spur gear 2t) and forms together with spur gear 2t) a sliding gear which is axially movable along hub 21of spool 154v Spur gear 23 has a larger diameter than spur gear 2t), so that as a result of turning of shaft 5 while spur gear 23 is in engagement with pinion gear 22, spool 15 is set intorotation.

By suitably changing the diameter of the gears, it is Ipossible to vary the speed of rotation andv also the direc- Patented June 18, 1957y 'arrangement 27 is provided on shaft 5 which can be brought into engagement with worm gear 4 by means of a lever system 2S. Lever system 28 is so arranged that the coupling and uncoupling of the coil winding machines can be carried out from the position of the operator located adjacent the spool.

As shown in Fig. 6, coupling member 27 has projecting portions 30 which are adapted to be moved into corresponding recesses 31 in worm gear 4. Coupling member 27 is axially movable along and keyed on shaft 5, being movable thereon for engagement with gear 4 by a yoke 33 riding freely in groove 34 in coupling member 27.

The multiple wire ceiling apparatus of the present invention has several advantages. When the machine is operated with a stationary spool, the wire can be wound with increased speed and the wire coils can be removed without danger of injury. The apparatus according to the present invention is also suitable for winding thicker types of wire, and particularly steel wire, on a rotating spool, the spool rotating slower than the speed of rotation of the coiling disc and therefore the wire can be `coiled in the range of speed of a machine which is equipped only with a rotating spool.

Each coil winding machine can be set into operation independently of the others, and it is thereby possible to coil simultaneously wire of different sizes and types on the apparatus. The planetary gear arrangement of each coil winding machine provides the correct direction of rotation and the speed of rotation, and the latter speed can be widely varied by suitable selection of the gear ratio and thereby adapt the machine to all needs. Instead of arranging the coil winding machines on both sides of the supporting housing, the machines may be arranged if desired only on one side.

The apparatus according to the invention incorporates into one device both constructions of the single coil lwinding machines known heretofore, without making necessary an increase in the overall dimensions of the machine.

It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of winding devices differing from the types described above.

While the invention has been illustrated and `described as embodied in wire Icoiling apparatus, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.

Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can by applying current knowledge readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the following claims.
