Definitions

  • ABSTRACT receiving means such as coil injection tooling or a coil transfer mechanism with or without auxiliary coil shaping means.
  • the apparatus may be advantageously utilized in the manufacture of wound inductive devices, e.g., dynamoelectric machines such as motors.
  • An illustrated preferred embodiment includes a frame, a coil form support having auxiliary coil shaping means embodied as a coil form'mounted thereon for axial movement relative to the frame, and a flyer rotatable about a central axis for developing wire turns on the coil form.
  • a migrating mechanical linkage is provided between the frame and coil form support to prevent rotation of the coil form with the rotating flyer.
  • the illustrated migrating linkage includes a carriage which supports a wobble face gear and is rotatable relative to the gear.
  • the wobble gear is provided with teeth on opposite faces thereof and the teeth on one face of the wobble gear mesh with the stationary gear teeth on the frame while teeth on the other face of the wobble gear engage the gear on the coil form support.
  • the stationary gear teeth and gear teeth on the coil form support are spaced apart and the wobble gear extends between the spaced gears so that portions of the wobble gear spaced 180 apart engage the stationary gear teeth and gear teeth on the coil form, respectively.
  • the wobble gear carriage is canted relative to the central axis and as it rotates it drives succeeding teeth on the faces of the wobble gear into engagement with succeeding ones of the stationary and coil form support gear teeth.
  • the wobble gear executes a rotationless wobble motion synchronized with the flyer. This motion results in a moving shutter, synchronized with the flyer, through which wire is fed to the flyer.
  • the present invention relates generally to improved apparatus for developing one or more coils in one or more coil groups and more particularly to a machine for developing coils that may be used as the winding in an inductive device, one example of which are dynamoelectric machine windings. More specifically, the present invention relates to high speed winding equipment having means for synchronizing a wire accommodating opening or shutter with movement of aflyer.
  • the coil receiver After having received the coilturns, the coil receiver is moved to a coil inserting or coil inject machine such as that disclosed in the Hill US. Pat. No. 3,324,536. Since a number of different size coils for a given coil group to be used to formone pole of an electric motor are often developed on a single form, the coil form is provided With steps or stages and relative axial movement between the form and flyer is effected so as to develop the different coils withina coil. group.
  • the form is moved in several steps, and may begin with the form retracted toward the head structure of the machine. Then, as all of the turns for one coil-are developed, the form would be moved one incremental step toward the coil receiver and the turns of a second coil would be developed. This stepping process would be repeated until a coil group for one pole would have been developed. This stepping process, of course, requires the coil form support structure to be movable axially.
  • the drive shaft which imparts rotary motion to the flyer is a tubular shaft surrounding the support.
  • shaft for the coil form and wire is fed from a wire source along this tubular drive shaft to the flyer.
  • This wire feed path is preferably kept close to the axis of the flyer drive shaft and coil form support so as to prevent undue stresses caused by bending and/or twisting of the wire as the flyer and drive shaft rotate.
  • one disclosed means for preventing rotation of a coil form included pairs of cam operated shuttle bars which sequentially locked the coil form support structure to the machine frame while providing a gap between the coil form support structure and the machine frame opposite the instantaneous shuttle bar locking point through which gap wire could be fed to the flyer.
  • the shuttle bars reciprocated between diametrically opposed locking points and thus accelerated in a first direction, stopped and latched, and then accelerated in a direction opposite to the first, stopped, and latched again for each revolution of the flyer.
  • the stresses and vibrations due to inertial forces involved with this arrangement established, as a practi cal matter, an upper limit to the speed of operation of the entire apparatus.
  • Cam operated shuttle bars were also utilized in our copending application Ser. No. 806,057, filed Mar. 1 l, 1969 and entitled METHOD AND APPARATUS FOR FORMING SHAPED INSULATORS AND FOR DE- VELOPING COILS OF A MAGNETIC CORE.
  • This application issued as U. S. Pat. No. 3,579,818 on May 25, 1971.
  • a coil form cooperates with an insertion tooling mechanism, e.g., injection tooling.
  • linearly reciprocating shuttle bars will also be a continuing cyclical stress generating source at all speeds of operation and will thus havea tendency at least to be a source of undesired noise as well as vibrations which can have a continuing deleterious afi'ectover a period of time on other parts of the apparatus, including for example, hydraulic and pneumatic seals and connections, electrical connections, and mechanical elements and adjustments.
  • Still another object of the present invention is to provide a machine having means extending between axially spaced apart first and second members for preventing relative rotation between the first and second members while allowing rotation of a wire handling structure which lies axially between the first and second members and extends radially beyond the axis of rotation of the wire handling structure.
  • a more specific object of the present invention is to provide a moving shuttle mechanism movable continuously with the flyer of a winding machine through which winding material is fed to the flyer.
  • an improved machine for developing groups of coils of winding material wherein winding material is fed to a rotating flyer.
  • the material is fed along a path generally parallel and in proximity to an axis of rotation of the machine and radially away from the axis of rotation between a first stationary machine element or mechanism and a second machine element or mechanism restrained from synchronous movement with the flyer by shutter means which extend between and constantly engage the first and second machine elements.
  • the first machine element includes a first meshing surface in the form of a face gear, held fixed relative to the machine frame.
  • the second machine element includes a meshing surface in the form of a second face gear secured to a coil form, and the shutter means is in the form of an intermeshing member having two spaced apart oppositely facing surfaces each of which respectively engage and mesh with the face gears.
  • the intermeshing member With the two face gears lying in spaced apart parallel planes, the intermeshing member lies in a plane intersecting the two parallel planes and is supported by a nonrotatable bearing race which is eccentrically supported relative to the axis of rotation by a bearing race which rotates in synchronism with the flyer.
  • the nonrotatable bearing race executes a rotationless wobble motion which is imparted to the intermeshing member.
  • the intermeshing member then defines a shutter synchronously movable with the flyer, through which winding material is fed to the arm of the flyer.
  • linearly reciprocating masses are avoided in the shutter defining means and undesirable ramifications thereof, such as vibration, and cyclincal inertial stresses are substantially eliminated.
  • FIG. 1 is a front perspective view of a winding machine embodying the present invention in a preferred form
  • FIG. 2 is an elevational view partially in section, of the winding machine head portion of the machine shown in FIG. 1;
  • FIG. 3 is a somewhat perspective view representative of the motion which portions of the machine head shown in FIG. 2 undergo during machine operation;
  • FIG. 4 is a view, partially in section, taken in the direction of the line 44 in FIG. 3;
  • FIG. 5 is an exploded perspective view of the machine elements shown in FIG. 3.
  • a coil winding machine particularly adapted for developing winding coil turns for dynamoelectric machine stators and embodying the present invention, in one form, includes a machine frame 11 which supports auxiliary coil shaping means illustrated as a coil form 29 about which flyer means including flyer arm 13 is rotatable.
  • the axis of revolution 15 (best seen in FIG. 2) of the flyer 13 may be horizontal but as illustrated is vertical as in the case of the flyer in the apparatus shown in our aforementioned copending application, the entire disclosure of which application is specifically incorporated herein by reference.
  • the coil form 29 of the machine 11 has sections for interfitting and cooperating with coil receiving means that, as illustrated, include the vertically extending blades of a coil transfer mechanism 71.
  • This mechanism is supported by a vertically movable transfer mechanism support structure 73.
  • the structure 73 is operative to raise the coil transfer mechanism into intermeshing relationship with the coil form 29 for receiving developed winding turns.
  • the support structure 73 rotates the coil transfer mechanism in preparation for receiving the coils developed for another coil group.
  • the support 73 lowers somewhat so that the transfer mechanism 71 may be removed by an operator and transferred to a coil insertion station.
  • Many of the principles of overall operation of the winding machine 11 are similar to those of the aforementioned Smith device although the machine axis 15 is vertical rather than horizontal and may, of course, include structural arrangements disclosed in our aforementioned copending application.
  • coil injection tooling or still other coil turn receiver means may receive coil turns developed from wire fed to the flyer 13.
  • a pair of electric motors 75 and 79 supply the power requirements of the present machine either by way of direct mechanical linkages such as a belt drive to the flyer mechanism 13 from the motor 75 or by a pneumatic system controlled for example by solenoid operated valves such as the valves in the valve banks 81 and 83 which serve to gate energy from a pressurized fluid supply to the pneumatically operated mechanisms within the machine 1 1.
  • the pressure fluid system and controls in the machine 11 may be arranged for pneumatic or hydraulic operation, but in either case the physical operation and control is basically as described in Smith US. Pat. No. 3,510,939.
  • the mechanism which rotates the transfer mechanism 71 is a pneumatic drive mechanism controlled by one of the valves in the valve bank 81 which, as will be understood, in turn is energized by a not shown logic circuit upon the completion of the development of a coil group.
  • a pneumatic cylinder is operative, upon actuation of the proper valve in valve bank 83, to drive a bearing plate 101 carried by the coil form jump tube 50 (better shown in FIG. 2) against retractable stops 102, 103, 104.
  • the coil form or arbor 29 is jumped downwardly upon sequential retraction of the stops 102, 103, 104 which also are pneumatically controlled.
  • FIG. 1 viewed in FIG.
  • control panel 87 by means of which an operator may, for example, set the number of turns required for each coil in a coil group.
  • Machine operation is initiated by simultaneous two handed energization of the switches 89 and 91.
  • a wire source such as a large drum 77 supplies wire along a wire guide 93 around two pulleys or other wire guides 95 and 97 and then downwardly substantially parallel to and adjacent to the axis of rotation of the fiyer 13 to the flyer.
  • the fiyer 13 is rotatably driven about the axis 15 by a tubular flyer drive shaft 17 which in turn is driven, for example, by the electric motor 75 of FIG. 1.
  • the entire flyer means including the flyer 13, the drive shaft 17 and flyer supporting structure 67 and 69 is illustrated cross hatched throughout in the same manner to more clearly show which portions of the machine rotate together.
  • the entire flyer means is rotatably supported by the frame by way of rotary bearings 19 and 21.
  • Wire from the source 77 shown in FIG. 1 is fed along the tubular drive shaft in a wire passage 23 which eventually bends and progresses radially outwardly along the structure which affixes or couples the actual flyer 13 to the flyer drive shaft 17.
  • This wire feed path is then deviated twice within the fiyer by two wire guides 25 and 27. From this last wire guide 27 the wire is fed as the flyer rotates and coil turns are developed about the coil form 29.
  • the coil form 29 is secured to a base 33 locked against rotation relative to a second member 31.
  • the coil form base 33 is movable axially relative to the second member 31 but relative rotation of these two portions of the coil form support means is prevented by a pin 35 secured to the base 33 which mates with a corresponding hole 37 in the base 33 of the coil form support structure, the hole 37 extending sufficiently far into the second member 31 to allow the desired amount of relative axial motion between the members 31 and 33 and yet prevent any rotation therebetween.
  • the coil form support structure 31 remains stationary while the flyer 13 rotates in order to promote the desired development of coil turns, this relative rotation being allowed while maintaining rugged support for the coil form and flyer by a series of rotary bearings 39, 41, and 43.
  • An axial rod 49 is the innermost of a series of concentric members 49, 51, and 17 which extend generally along the axis 15.
  • the axial rod 49 is movable axially relative to the coil form 29 to ensure that all of the coil turns developed during a coil winding cycle are received in the coilreceiving means.
  • the axial rod 49 and jump tube 51 may be moved together axially to move the coil form 29 axially relative to the flyer for winding coils having varying pitches or turn diameters on successive ledges of the coil form. The provision for this operation is also fully discussed in the aforementioned Smith patent.
  • the last or outer axial tube 17 is, as presented earlier, supported for rotary motion about the axis 15 and does not undergo axial displacement.
  • the flyer drive shaft or outer axial tube 17 supports in a fixed manner an eccentrically mounted rotatable bearing support structure 53 which in turn supports the rotatable races for a pair of rotary bearings 55 and 57.
  • This support structure or frame 53 is canted with respect to the axis 15 having its own axis inclined thereto at an angle of, about 5 degrees which, as will be understood, may be varied as desired.
  • the outer races of the bearings 55 and 57 rotatably support a collar 59 to which is affixed an annular member 61 having two oppositely facing meshing means that are illustrated in the form of annular gear teeth as readily seen in FIG. 5.
  • the frame 53 rotates with the tube 17 and due to the canted relationship of the frame 53 relative to the axis 15, the high and low points of the frame 53 relative to the coil form 31, will rotate about the axis 15.
  • the annular member 61 will execute a wobbling nonrotary motion about the tubular flyer drive shaft 17 as the shaft rotates. This motion is nonrotary because the member 61 is locked against rotation by reason of its engagement with stationary meshing means shown as the face gear 63 secured to the machine frame.
  • the face gear 63 gear surface is substantially perpendicular to and centered about the axis 15. It will be understood that the intermeshing surfaces or teeth on the members 61 and 63 may be a series of spherical protrusions and corresponding spherical indentations or other slip preventing meshing surface configurations.
  • the first portion of the coil form support member 31 is provided with a meshing surface in the form of a toothed surface 65 of annular configuration which meshes with the lower toothed surface of the annular member 61 as viewed in FIG. 2.
  • the flyer 13 is supported on a drum like structure 67 having an end 69.
  • This end 69 is not radially symmetrical but rather, in the position illustrated in FIG. 2, has portions removed to allow the facing teeth of the gears 61 and 65 to intermesh while the diametrically opposite teeth on the gear 61 intermesh withthe gear 63. While in this position, there is sufficient room between the face of gear 61 and the gear 65 at the left side of FIG. 2 to allow the wire guide portion of support end 69 to pass between the gears 61 and 65.
  • This portion of end 69 is attached to the flyer drive shaft 17 and the flyer 13.
  • this region between the gears 61 and 65 may be utilized as an open shutterfor feeding wire radially outwardly relative to axis 15 and between the gears 61 and 65.
  • the wire feed path 23 extends from the wire source 77 along the flyer drive shaft 17 through the annular gear structure 61 and then radially outwardly along the flyer support 69 to the flyer.
  • the illustrated embodiment includes a migrating linkage that prevents rotation between two members and yet allows winding material to pass radially outwardly of and between these two members in synchronization with the migration of the linkage.
  • gears 61 and 63 might for example have a pitch half that of the intermeshing portions of the gears 61 and 65.
  • gear 61 might be deleted and in its place a pair of intermeshing gears be provided having two parallel axes that are perpendicular to the machine axis 15. One of these gears would mesh with the gear surface 63 and the other gear would mesh with the gear surface 65.
  • the carriage for these two gears would, of course, be supported on the flyer drive shaft 17 for rotation therewith so that the axes of the gears would move through two parallel planes perpendicular to the axis 15.
  • a pair of gears locked or keyed on a common shaft which is parallel to but removed from the machine axis could be used so long as the pair of gears is supported by and rotates with the flyer struc-' ture and each meshes with a gear structure on the frame and coil form support.
  • strain wave gearing techniques may be utilized.
