4 Claims.
This invention relates to the winding of coils into slots, more particularly in electrical work.
This invention has utility when incorporated in ready mounting or holding and control of the part to be wound, as an armature, and the carryme thru of the successive steps therefor to complete the winding of such article.
Referring to the drawing:
Fig. l is a side elevation, with parts broken away, of an embodiment of the invention in an armature winder;
Fig. 2 is a wiring diagram of the electrical connections and controls for the winder of Fig. 1;
Fig. 3 is a detail view, on an enlarged scale, looking into the armature holder or head from the right of Fig. 1;
Fig. 4 is a plan View of the holder of Fig. 3, portions being broken away to show details of the electromagnet; and
Fig. 5 is a fragmentary View of a substitute guide and seat as an adapter to a different dimen- 'sion armature.
therefrom, adapted thru magnetic clutch 3 to be cut in to drive a shaft 4 extending into speed reduction housing 5. The speed reduction in the housing 5 may have a manual adjustment or control 6 to vary the speed of a shaft l.
The electromagnetic holder The device of the invention may be mounted by a set screw 8 to rotate with the shaft 7. The set screw 8 is in a head member or overhangS having thereon an insulation sleeve H) for a pair of slip rings |2. The member 9 terminates therebeyond in a block |3 of nonmagnetic material.
Bolts |4 thru the block l3 mount magnet legs H3 in parallel. A bolt l6 therebetween has a magnetic core H in an electric coil winding l8, The free ends of the legs I5, remote from the block |3, have are faces or seat portions l9.
Mounting an armature to be wound The article of work, as an armature 24, upon approach to the arc seats 2|, has its ends 25 ride just inside the seat faces 2|, for the energized electromagnet draws the armature 24 to abut the faces 9 to be there magnetically locked or held. In this transit to the holding position for work thereon, the armature 24 is so shifted as to have a slot 2% of the armature entered by the indexing pin 23. The deflector portions or guides 22 are so located that from a coil supply 2'! to pass over a guide roller 28, the insulated wire 29 to be wrapped will be directed, upon the rotation of the shaft f, to enter a slot 26 of the armature 24, then pass across the end of the armature 24 clear of its shaft to enter a second slot in the winding pair for the armature coil. The guides or deflectors 22 are so configured, that at the location of the feed direction for the wire 29, the wire 29 is directed to be wrapped directly into the pair of slots of the armature. V i t From the drive shaft 4, a transmission 30 extends to a counter device 3| to operate a cut-out switch 32 as the number of turns of wire 29 in a pair of armature slots 25 comes to the designated total. 7
The control electric current. it is then desirable to minimize.
the hysteresis loss and have the electromagnet laminated. For direct current ower supply to the coil 18 of the electromagnet, the core H and legs l5 may or may not be laminated Upon throwing in or closing a switch 33, electric power supply line 34 is connected to the motor with its circuit completed to the circuit completing power line 35, to start the motor The closing of the switch 33 does nothing else but start the motor I. The operator determines the number of turns of wire to be placed in the pair of slots of the armature. Should stop pin 36 be not properly located therefor at the counter device 3%, the pin 36 is relocated in the proper adjustment opening 3! therefor. Arm 38 in cam disk 39 is then swung against the properly located pin 36. In so doing, a stop 40 is moved by the cam against the resistance of a spring 4| to close the switch 32. The operator may then close a switch 52 on the front of the housing 5 as a manual control cut in for the coil l8. The electromagnetic holder is now energized for the placement of the article of work, as an armature 24 in the rotary head or holder to be there indexed and at once looked magnetically. It is next in order for the operator to step on a switch 43, which is effective, with the switches 33, 32, also closed, now to energize the magnetic clutch 3. The motor is now effective thru the shaft 4 and the speed reduction in the housing 5, to rotate the shaft 1 and the winding head thereon carrying the armature 24. The operator may at any time stop the rotation of the winding head and armature 24, by releasing the switch 43. This does not disturb the counter device 3| and its switch 32. Accordingly, should such stop by the operator be to cure some defect in thewire, then at once such be rectified, the winding continuation is automatically effective to the initial total, when the switch 32 is opened by the rotation of the cam disk 39 clockwise (Fig. 2) permitting the stop 40 to be drawn into the cam recess by the spring 4|. The operator may then open the switch 42 to release the armature 24, so that it may be rocked to the next slot pair to receive the succeeding coil. Closing of the switch 42 is then effective to relock the armature in the new or reset position. Stepping on the switch 43 is delayed until the arm 38 has been thrust against the pin 35. With such preliminary cared for, the operation cycle may be repeated.
For shops where rewinding or job work has quite a range of sizes to be considered, substitute parts may be provided. In lieu of the poles !5, there may be poles 44, with projecting fingers 45 to be attached as interfitting with projections 46 with which there is fixed arc seat face 41 upon a different radius than that of the seat I 9, when for a different diameter article of work. As end keeps or limit stops, arc means 48 (Fig. 5) are of a form to coa-ct in the same manner as the arc end seats 2|. In this adaptation, instead of assembly of the deflectors 22 and seats 2|, with the head, the substitute parts may be a unit, magnetically responsive. This unit has deflector portions 49 and indexing pin 50.
In the circuit for the energizing coil l8 of the electromagnet, the slip rings ll, I2, have brushes 5| ride thereon. By placing the single coil l8 crosswise of the axis of the rotary head I3, l5, IS, the magnetic circuit thru the armature is from a pair of poles, in lieu of three poles were the coil coaxial with the head to require a central pole between the outer pair.
What is claimed and it is desired to secure by Letters Patent is:
1. A coil winder comprising a non-magnetic support, a pair of arc-faced magnet opposite poles extending from the support and forming a seat complementary to a. longitudinally slotted armature adapted to be magnetically locked therewith as an article of work, and non-magnetic guide wings mounted on the poles for directing wire to be wound directly to exposed slots adjacent the seat.
7 2. A coil winder comprising a pair of opposite pole magnet arc faced seats adapted directly to engage armature face portions as boundin armature slots, energizing means for the poles for the magnetic circuit therefrom to be completed thru an armature at the pole seats, and non-magnetic means carried by the winder poles adjacent the seats providing end seats between which the armature is located by the energizing of the poles, said non-magnetic means having flare outward wing connections to direct wire to be wound to- Ward the slots of the armature upon relative rotation thereof.
3. A coil winder comprising a rotary head having a seat complementary to the face of an article adapted to be located therein, said article having a shaft and slots parallel to the shaft to receive line windings to form a coil by winding into a pair of slots, deflector means carried by the head to extend toward but short of to the shaft, and adapted upon rotation of the head to direct the line to be wound from a supply into the pair of slots of the article in the head, and selective electrical control means for locking the article to the head andv releasing it therefrom, and for stopping the head after a predetermined number of rotations.
4. A coil winder comprising an electromagnetic rotary two pole head having spaced opposite'pole magnetic face portions providing a seat complementary to a longitudinally slotted cylindrical armature having a shaft protruding therefrom beyond the ends of the slots, deflector means for the line to be wound carried by the head, and indexin means at the seat to position a pair of.
slots inward from the shaft and outward from the deflector means, whereby energizing of the electromagnet automatically locks and simultaneously positions the armature in the head to form a coil therein upon rotation of the head.
