Definitions

  • the formers move at least to a winding position where they are wound and to a removal position where at least one former of the group is swiveled to be parallel to another former of the group for simultaneous removal of the coils from the two parallel formers.
  • This invention relates to the handling of formers of the type used for winding wire coils for electrical machines and the like.
  • this invention relates to an improved method and apparatus for manipulating the formers relative to coil winding and coil removing stations.
  • This purpose of the present invention is achieved by providing an arrangement wherein a plurality of formers are mounted for movement together at least between a winding position whereat they can be individually wound and a removal position whereat adjacent formers are oriented so that they are parallel to each other so that the two coils wound on the parallel formers can be removed simultaneously.
  • the apparatus would include a group of formers located in a common plane and all extending outwardly from a cen- 3,624,898 Patented Dec.
  • capacity of the apparatus may be doubled by simply providing a second group of formers lying in a plane parallel to the first said common plane and rotatable about the same central axis.
  • a second group of formers lying in a plane parallel to the first said common plane and rotatable about the same central axis.
  • FIG. 1 is a side elevational view of a former holding apparatus constructed in accordance with the present invention and showing two groups of formers.
  • FIG. 2 is a plan view of the apparatus showing FIG. 1.
  • FIG. 3 is a schematic view showing in side elevation the mechanism for effecting swiveling of the formers.
  • FIG. 4 is a plan view of the apparatus shown in FIG. 3.
  • FIGS. 5a to 5 illustrate the operation of the embodiment in FIGS. 1 through 4 in the production of a twopole motor.
  • FIGS. 6a through 6 illustrate the operation of another embodiment of the invention for use in the production of a four-pole motor.
  • FIGS. 1 and 2 there is shown an apparatus constructed in accordance with the features of the present invention and including two groups of formers.
  • the first or upper group includes formers 1a, 2a, 3a and 4a spaced generally about and extending outwardly from a central axis 9.
  • the second or lower group consists of formers struction and including in this case three steps for 1b through 4b, also extending outwardly from the central axis 9.
  • the individual formers are of conventional conforming the separate portions of difierent sizes, and each former comprising two halves with a space between the halves into which the formers move for releasing the wound coils. Coils are wound onto the formers at the winding station 7 which comprises a pair of vertically aligned conventional winding funnels 8a and 8b. As the groups of formers are turned about axis 9, they move in succession to the said winding station.
  • the apparatus further includes a set of bearing plates including an upper bearing plate 16, a central bearing plate 17, and a lower bearing plate 18. Connected to these bearing plates and extending from plate 16 to plate 18 are four swivel axis rods A, B, C and D.
  • the formers in the upper group are connected to axes A and B. Specifically, formers 1a and 4a are mounted for swiveling movement about the axis rod A while the other two formers 2a and 3a are mounted for movement about axis rod B.
  • the formers in the lower group are mounted for swivel movement about the other two axis rods C and D. Specifically, formers 1b and 2b are mounted for swiveling movement about axis rod C and formers 3b and 4b are mounted for pivotal movement about axis rod D.
  • the apparatus is turned in steps of 90.
  • one former of each group is located in its respective winding funnel 8a and 8b.
  • the winding funnels 8a and 8b are withdrawn after which the apparatus is turned another 90 (assume that turning is in the clockwise direction as viewed in FIG. 2) to place the two formers 3a and 3b into the winding position to be operated on by the respective winding funnels 8a and 8b.
  • each step while two of the formers a-re having coils wound thereon, two other formers in at least one group which were previously wound with coils are moved to such a position that they are parallel to each other whereby the coils wound thereon can be simultaneously removed therefrom.
  • this particular arrangement may be used for two groups of coils which are to be used in the manufacture of a two-pole motor, one coil forming each pole.
  • the formers 4a and 4b are shown in their respective funnels 8a and 8b while the two formers 2a and 3a are parallel to each other, the two formers having been swiveled about the axis rod B, whereby the coils on these two formers can be removed simultaneously.
  • the apparatus would be turned clockwise 90 (as viewed in FIG. 2). This would place the formers 3a and 3b in the respective funnels 8a and 8b. Concurrently the lower formers 1b and 2b would swivel about the axis C to become parallel to each other for simultaneous removal of the coils thereon. The apparatus would then be turned clockwise another 90 placing the formers 2a and 2b in the respective winding funnels 8a and 8b and placing the upper formers 1a and 4a into the position whereat they are turned about the swivel axis A into parallel relationship with each other for simultaneous removal of the coils mounted thereon.
  • FIGS. 3 and 4 This arrangement includes a cam fixed against rotation at the top of the apparatus together with a follower 11 which follows the outer circumferential surface of the cam and is connected by a lever 12 to an axis rod.
  • FIGS. 3 and 4 the elements 11 and 12 for the axis rod B are shown. However, similar elements are provided for each of the other three axis rods. As can be seen from FIG.
  • the follower 11 is normally displaced outwardly from the center of axis 9 by the distance R.
  • the cam has a radius 1'.
  • the follower 11 and the lever 12, and hence the axis rod B turn slightly in the counterclockwise direction as viewed in FIG. 4.
  • This axis rod B is non-rotatably fixed to the former 311 by means of a pin 5 as shown in FIG. 3, thereby turning the former 3a.
  • the other former 2a is loosely mounted on the axis rod B and thus additional means must be provided for effecting movement of this former.
  • the gear 15 is fixed with respect to former 2a but is loosely mounted on rod B.
  • the gear 13 is fixed onto rod B.
  • the gear 13 which acts through a gear train including gears 30, 31 and 32 to turn the gear 14 which in turn turns the gear 15 to turn the former 2a about the axis of rod B so that it is parallel to the former 3a.
  • the gears 14 and 15 are shown spaced apart for purposes of convenience. However, in practice these two gears would be engaged with each other.
  • rollers 11 would be maintained against the surface of cam 10 by suitable means such as a spring or the like.
  • FIGS. 5a through 5 The operation of the embodiment of FIGS. 1 through 4 is shown in greater detail in FIGS. 5a through 5), especially with respect to the production to a two-pole singlephase or double-phase motor.
  • the formers of the upper group are shown in three successive operational steps in FIGS. 5a, 50 and 5e and the formers of the lower group are shown in the same operational steps at FIGS. 5b, 5d and 5 In the illustrated steps, all formers have already passed at least once through their respective winding funnels 8a and 8b.
  • the formers 4a and 4b are having coils wound thereon. Meanwhile, the two formers 2a and 3a have just had wound coils removed therefrom.
  • the former 3b already had its wound coil removed therefrom during the preceding step, simultaneously with the coil then present on former 4b.
  • the apparatus is then turned placing the formers 3a and 3b into their respective Winding funnels and placing the lower formers 1b and 2b into parallel relationship for simultaneous removal of the coils wound thereon.
  • formers 2a and 2b are wound with coils while formers 1a and 4a simultaneously have their wound coils removed.
  • the present invention has the further advantage that the coils on two adjacent formers which will subsequently be swiveled into a parallel relationship with each other to have their coils simultaneously removed have been wound directly one after the other with the same winding funnels so that it was not necessary to cut the wire between winding the two said formers. This provides a desired connection between the two groups of coils which would otherwise have to be added.
  • FIGS. 1 through 5 illustrate only one form of the invention. In practice, it is possible to include any number of planes or groups of formers and to provide various numbers of formers within each group.
  • FIGS. 6a through 6 illustrate a different arrangement wherein there are two groups of formers, each having six formers therein.
  • the upper group includes formers 21a through 26a and the lower group includes formers 21b trhough 26b.
  • the bearing plates and axis rods are replaced by middle and lower bearing plates 19 and 20 and new axis rods E, F, G and H. Except for the different number of elements and the different positions of the axis rods, it is to be understood that the details of the various elements are precisely the same as shown with respect to the emlodiment of FIGS. 1 through 5.
  • FIGS. 6a through 6f operates as follows. This apparatus is turned in steps of 60 about the central axis 9, thereby requiring six steps to complete its cycle. The first three of these steps are shown in the drawings and the remaining three steps can easily be derived therefrom.
  • FIGS. 6a, 6c and 6e show the upper group of formers in the first three steps, respectively, while FIGS. 6b, 6d and 6 show the same said first three steps with respect to the lower group of formers.
  • the formers 21a and 21b are being wound in the winding funnels 8a and 8b, respectively while formers 24a, 25a 24b are arranged parallel with each other, having been swiveled about axis rod G.
  • three parallel arranged formers have coils removed therefrom simultaneously including two formers in one group and a former in the other group.
  • no axis rod is located at the removing station (which is the lowermost station as viewed in the figures) and hence no formers are so positioned to have coils removed therefrom.
  • the three formers 23a, 22b and 23b have been swiveled about the axis rod F to be parallel to each other for simultaneous removal of the coils wound thereon.
  • An apparatus for use in the production of Wound coils for stators and the like comprising a holding means for holding a group of formers onto which coils can be wound with the formers being arranged in a common plane and extending outwardly from and turnable about a common axis generally perpendicular to said plane, and for moving said formers to a winding station Whereat the formers are wound individually and to a removing station, and including a means for re-orienting at least one former of the group at said removing station within said common plane such that the re-oriented former and at least one other former of the group are arranged generally parallel to each other at said removing station whereby wound coils can be removed simultaneously from the two said generally parallel formers.
