Abstract
Abstract Apparatus including circularly arranged transfer bars movable to protrude axially from the front end of a former to automatically transfer wound coils from the former to mounting fingers of a device which inserts the wound coils in the stator grooves. A control device regulates feeding of wire to the former to form the coils in a manner which facilitates subsequent transfer of the coils from the former.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
125 words
An apparatus for use in the production of coils for stators of electrical maChines and the like comprising, a former adapted to have a coil wound thereon, a set of transfer bars extending axially through the former; coil inserting means for receiving a wound coil from the former and inserting the same into the grooves of a stator, said inserting means including a set of generally parallel mounting fingers, said former being positionable in a transfer position wherein said transfer bars are generally parallel to said mounting fingers and wherein the transfer bars protrude axially from said former with their outer end positioned adjacent said mounting fingers whereby a wound coil can be moved from the former, along said transfer bars onto said mounting fingers.
Claim 2
Independent Claim
125 words
An apparatus for use in the production of coils for stators of electrical maChines and the like comprising, a former adapted to have a coil wound thereon, a set of transfer bars extending axially through the former; coil inserting means for receiving a wound coil from the former and inserting the same into the grooves of a stator, said inserting means including a set of generally parallel mounting fingers, said former being positionable in a transfer position wherein said transfer bars are generally parallel to said mounting fingers and wherein the transfer bars protrude axially from said former with their outer end positioned adjacent said mounting fingers whereby a wound coil can be moved from the former, along said transfer bars onto said mounting fingers.
Claim 3
Dependent Claim
48 words
An apparatus according to claim 1, wherein said transfer bars are movable axially within said former at least between a withdrawn position, wherein the said outer end are located within the former, and an extended position wherein said transfer bars protrude axially from the front of the former.
Claim 4
Dependent Claim
22 words
An apparatus according to claim 1, wherein said transfer bars are arranged circularly such that their longitudinal axes generally define a cylinder.
Claim 5
Dependent Claim
52 words
An apparatus according to claim 3, including a plurality of formers arranged parallel to each other, and wherein the said transfer bars are arranged, relative to said formers, such that the coils on the formers can be moved simultaneously from said formers, along said circularly arranged transfer bars to said mounting fingers.
Claim 6
Dependent Claim
43 words
An apparatus according to claim 1, wherein said former includes a plurality of steps for forming coils of different outer dimensions, wherein at said transfer position, the coils on all of said steps are moved over said transfer bars to said mounting fingers.
Claim 7
Dependent Claim
62 words
An apparatus according to claim 5, including a plurality of formers arranged parallel to each other, each having a plurality of said steps, said transfer bars being arranged circularly to generally define a cylinder, wherein in said transfer position the coils on the two formers can be simultaneously moved from said formers, along said circularly arranged transfer bars to said mounting fingers.
Claim 8
Dependent Claim
82 words
An apparatus according to claim 1, including a winding arm rotatable in relation to said former for distributing wire thereon to form said coil, feed means for controlling the axial position of the winding arm relative to said former, and control means for controlling the speed of operation of feed means in response to the speed of rotation of said winding arm, so that the wire is placed onto the former in a single layer so that no wire crosses another wire.
Claim 9
Dependent Claim
54 words
An apparatus according to claim 7, wherein said former includes a plurality of steps for forming coils of different outer dimensions, and wherein said control means includes means for controlling the speed of operation of said winding arm as it distributes wire onto all of said steps so that no wire crosses another wire.
Claim 10
Dependent Claim
51 words
An apparatus according to claim 8, wherein said transfer bars are arranged circularly to generally define a cylinder, and wherein the control mean is arranged such that movement of the feed means to move the coil from one step of the former to the next occurs radially outside of said cylinder.
Claim 11
Dependent Claim
52 words
An apparatus according to claim 7, wherein feed means comprises a fluid cylinder and said control means comprises a signal generally responsive to the speed of rotation of the shaft of the winding arm for varying the pressure of fluid delivered to the fluid cylinder to vary speed of the feed means.
Claim 12
Dependent Claim
25 words
An apparatus according to claim 10, including adjusting devices for adjusting said signal to determine the characteristics of the turns of wire of the coils.
