7 Claims. (Cl. 242-355) v ABSTRACT OF THE DISCLOSURE Apparatus for winding material onto spools wherein a plurality of arbor members are supported for rotation about an axis and for relative axial movement therebetween to receive and support spools between adjacent ones of the members and to effect a driving connection with the spools for rotation of the spools together in response to rotation of the end arbor member by a selectively operable drive therefor.
This invention relates to a coil winding apparatus, and more particularly to an apparatus for winding coils simultaneously on a plurality of coil supporting forms.
Heretofore, as far as is known, coils supported on a particular type of individual coil supporting form, such as spools having iron cores therein, were wound one at a time. Manifestly, this method of winding spool supported coils individually is time consuming and ineflicient.
An object of the present invention is to provide an apparatus for winding simultaneously a plurality of coils on individual coil supporting forms.
An apparatus illustrating certain features of the invention for simultaneously winding coils on a plurality of spools may include a motor-driven headstock supported in a frame for rotation about a horizontal axis. The headstock has a seat for receiving and supporting one end of a spool for rotation about the axis and for effecting a driving connection therewith. Supported movably on a slide of the frame below the axis are brackets in each of which a coupling member is mounted for rotation about the axis and for axial movement with the bracket. One end of the coupling member is provided with a seat for supporting the other end of the spool and effecting a driving connection therewith.
The opposite end of the coupling member is provided with a seat for supporting the first end of another spool and effecting a driving engagement therewith. Several of such brackets and spool supporting coupling members may be provided to support a plurality of spools in a row in interconnected relation to one another. A tailstock is supported on the frame for rotation about the axis and for supporting the other end of the last spool of the row of spools. By means of a lever, the tailstock is moved toward the headstock to an operative position to effect the clamping of the spools between the headstock, the coupling members, and the tailstock for rotation together in response to rotation of the headstock.
Other objects, advantages and novel aspects of the invention will become apparent upon consideration of the following detailed description, in conjunction with the accompanying drawings, in which:
FIG. 1 is a fragmentary side elevational view of the coil winding mechanism embodying the present invention;
FIG. 2 is a side elevational sectional view of a coil supporting spool of a type on which a coil is to be wound in the present apparatus;
FIG. 3 is an end view of the coil shown in FIG. 2;
FIG. 4 is an enlarged fragmentary plan sectional view of the apparatus taken on the line 44 of FIG. 1;
United States Patent Referring to the drawings, the present apparatus is designed to wind simultaneously a plurality of coils on coil supporting forms such as composite spools 12. Each composite spool 12 comprises a dielectric spool 13 having a sleeve 14 and round and square heads 15 and 16, respectively, at opposite ends of the sleeve, and an iron core 18 supported within the sleeve and with the ends of the core projecting slightly beyond the spool. A plurality of terminals 20 are secured to the square head 16 and extend therefrom in a direction parallel with the axis of the spool. The round spool head 15 has an aperture 22 formed therein.
The coil winding apparatus comprises a drive shaft 25 which is supported in a frame 26 for rotation about a horizontal axis 28 and is driven by a motor 30. Secured to the drive shaft 25 is a headstock 32 which serves as a holder for supporting the terminal end of a composite spool 12 for rotation about the axis 28. The headstock has an axially directed shank 34 at the end of which is formed a circular flange 36. The flange is provided with a recessed seat 38 having a square portion 39 for receiving the square head 16 of the spool and establishing a driving connection therebetween and having a portion 40 for receiving the projecting end of the core 18. In addition, the flange is provided with clearance apertures 41 for receiving the terminals 20 of the spool 12.
The opposite end of the spool is supported in a seat 44 of a holder or coupling member 46. The coupling member is supported in a ball bearing 48 and is mounted therewith in a vertically disposed portion of an adjustable L-shaped bracket 50. The lower portion 51 of the bracket is provided with a dovetail slot 52 (FIG. 5) and is mounted on a dovetail guide 53 for horizontal movement parallel to the axis 28. The guide 53 is fixedly mounted on a spacer 54 which is secured to a horizontal portion 55 of the frame 26.
The coupling member 46, in the recessed seat portion 44 thereof, is provided with a projecting pin 58 (FIG. 4) which engages in the aperture 22 of the round head 15 of the composite spool 12 for eifecting a driving connection therewith. At the opposite end thereof, the coupling member 46 has a shank portion 60 extending axially from the bracket 50, and has a circular flange 62 formed on the end of the shank similar to the flange 36 on the headstock 32. In like manner, the coupling member 46 is provided with a recessed seat 64 for receiving the square spool head 16 and effecting a driving connection therewith and for receiving the end portion of the core 18, and is also provided with apertures 66 for receiving the terminals 20.
A plurality of the adjustable brackets 50 and coupling members 46 is provided for supporting a plurality of the spools 12 between adjacent ones of the coupling members 46.
A tailstock 68 is provided which has a recessed seat 69 for receiving the head 15 and end portion of the core 18 of the spool 12 and which cooperates with the adjacent coupling member 46 to support the last spool of the row of spools. The tailstock has a spindle 70 and is mounted therewith in a sleeve 72 for rotation and against axial movement relative thereto. The sleeve 72, in turn, is mounted for axial movement in the bore of a cylindrical shell 74 and is stressed for movement toward the headstock 28 to a normal position against a ledge 75 of the shell by a spring 76 interposed between a threaded plug 77 in the shell and the sleeve 72. The shell is supported 89 for limited axial movement in a bore 79 of a supporting bracket 80 which is fixedly secured to the frame 26.
Mechanism under control of an operating lever 81 is provided for imparting axial movement to the cylindrical shell 74 to move the tailstock 68 to and from an advanced position in engagement with the end spool of a row of spools (FIG. 1) and a retracted position (FIG. 4). A shaft 82 is connected to and supports the lever 81 for pivotal movement on the supporting bracket 80 and has a crank disc 83 secured thereto. A crank pin 84 on the disc 82 has a roller 85 thereon which rides in a vertical slot 86 in the cylindrical shell for imparting axial movement of the shell and the tailstock in response to actuation of the lever.
As the lever 81 is moved to its operative position and the tailstock 68 is moved into engagement with the endmost spool 12, the spring 76 is compressed and stresses the tailstock toward the headstock 32 to effect the movement of the spools 12 and the spool supporting members; namely, the headstock 32, the coupling members 46, and the tailstock 68, into engagement with one another, and .the clamping of the spools 12 between adjacent ones of the spool supporting members for rotation together.
A handwheel 88 is secured to the drive shaft adjacent the headstock for manual adjustment thereof to facilitate the placement of the spools 12 in winding position in the apparatus.
In the operation of winding coils onto the spools 12, each of the spools to be wound has the leading end of a wire 78 (FIG. 1) from a supply thereof attached to a terminal 20 of the spool and wound partially around the spool sleeve and secured thereto adjacent the square head 16 by suitable means such as adhesive tape. It will be understood that the first bracket 50 has been moved previously to the left as viewed in FIG. 1 to provide clearance for the placement of the first spool 12 into the winding apparatus. The first spool is moved so as to insert the terminals 20 into the apertures 41 in the flange 36 of the headstock and to place the square head 16 and end of the core 18 in the seat 38 of the headstock and thereby establish a driving connection therewith. With the spool 12 held in alignment with the axis 28, the adjacent bracket 50 is moved toward the headstock to bring the coupling member 46 into engagement with the spool 12 and effect the nesting of the round spool head 15 and core end in the seat 44 of the coupling member 46 and the insertion of the pin 58 in the recess 22 of the spool head 15. The spool 12 is thereby interconnected with and supported by the headstock 32 and coupling member 46 for rotation therewith about the axis 28.
Thereafter, the terminal end of successive spools 12 are inserted in the seat 64 of successive coupling members 46 and the cooperative adjacent brackets 50 are moved into engagement with the opposite end of the spools to effect the support and interconnection of the several spools 12 and coupling members 46. After the terminal end of the last spool has been nested in the seat 64 of the last coupling member 46, the lever 81 is moved to operative position to effect movement of the tailstock 68 to the advanced position in nesting engagement with the other end of the spool 12, and the compression of the spring 76 of the tailstock to maintain the spools 12 and the spool supporting members 32, 46 and 68 in interconnected relation to one another during the coil winding operation.
On completion of the winding of the row of coils, the lever 81 is moved to its starting position to effect the return of the tailstock 68 to its retracted position in disengaged relation to the endmost spool 12 and permit the removal of successive ones of the wound coils from the apparatus.
It is to be understood that the above-described arrangements are simply illustrative of the application of the principles of this invention. Numerous other arrangements may be readily devised by those skilled in the art which will embody the principles of the invention and fall within the spirit and scope thereof.
