Abstract
Abstract An armature winding machine of the type wherein the ending and starting leads of the coils successively wound onto the core by a pair of oppositely rotating flyers, are attached to the segments or bars of the commutator of the armature by stuffing them into slots cut into the bars, which machine is characterized by the provision of automatically functioning means to assure exact alignment between the lead tucking blades of the lead attaching instrumentalities and the commutator slots before the leads are driven into the slots, this being accomplished by optical sensing means which takes cognizance of the position of the commutator slot with respect to the lead attaching instrumentalities, produces a signal indicative of that relationship and initiates the operation of corrective drive means by which the lead attaching instrumentalities are brought into exact alignment with the mouth of the slot.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
308 words
An armature winding machine of the type wherein coils of wire are successively wound into angularly spaced pairs of slots in the core of an armature core assembly which consists of a slotted core and a commutator having electrically spaced bars fixed on a common shaft, wherein said assembly is rotatably indexed to bring the different angularly spaced pairs of its coil receiving slots into winding receiving position, and wherein the beginning and ending leads of the successively wound coils are connected to selected ones of the commutator bars by inserting the same into slots cut into the bars, said machine being characterized by: A. lead attaching instrumentalities comprising lead holding, lead guiding and lead inserting means by which a lead going to the start of a coil to be wound and/or a lead coming from the end of a just-wound coil is held in juxtaposition to the mouth of the commutator bar slot into which it is to be inserted, is guided to the mouth of said slot and is inserted into the slot; B. armature core assembly gripping means having an axis and operable to coaxially grip said assembly, said armature core assembly gripping means and said lead attaching instrumentalities being relatively rotatable about said axis to enable a selected commutator bar and the lead attaching instrumentalities to be brought into juxtaposition; C. instrumentalities operative to produce a control signal that is indicative of the exact location of the mouth of each commutator bar slot with respect to the lead attaching instrumentalities; and D. drive means controlled by said signal and operative to effect relative rotation between said armature core assembly gripping means and said lead attaching instrumentalities as required to align the mouth of the slot in the selected commutator bar exactly with the lead guiding and lead inserting parts of said lead attaching instrumentalities.
