Abstract
Abstract Apparatus for winding electric stator coils comprises a templet onto which the coil wire is wound and from which the wound coil is stripped, a rotatable wire-guiding device for winding wire in coil form onto the templet, and a transfer tool relatively movable axially in the templet and onto which the wound coils can be stripped from the templet. During the winding process, the rotating wire guide is relatively moved axially in a direction away from the transfer tool relative to the templet, and the transfer tool is relatively moved axially toward and into the templet, whereby the templet is essentially in coil transfer position on the transfer tool at the end of the winding process. Preferably the wire guide and the transfer tool are axially stationary, and the templet is moved axially during the winding process. The transfer tool preferably is a drawing-in tool, and several winding and drawing-in stations are provided through a rotary table arrangement.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
171 words
In apparatus for the winding of wire coils which can be drawn axially into a stator of an electric machine, having a templet onto which the coil wire can be wound and from which the wound coils can be stripped, a rotatable wire-guiding device for winding wire in coil form onto said templet, and a transfer tool relatively movable axially into said templet and onto which the wound coils can be stripped from the templet, the improvement comprising means for effecting relative movement of said wire guiding device continuously in a direction axially away from said transfer tool relative to said templet and relative movement of said transfer tool continuously axially toward and into said template during winding movement of said wire guiding device, and hence during the whole winding process of a coil, said templet having an axially extending untapered surface portion onto which the wire coming from said wire-guiding device is placed such that all the turns of a coil are accumulated on the templet before removal from it.
Claim 2
Dependent Claim
171 words
In apparatus for the winding of wire coils which can be drawn axially into a stator of an electric machine, having a templet onto which the coil wire can be wound and from which the wound coils can be stripped, a rotatable wire-guiding device for winding wire in coil form onto said templet, and a transfer tool relatively movable axially into said templet and onto which the wound coils can be stripped from the templet, the improvement comprising means for effecting relative movement of said wire guiding device continuously in a direction axially away from said transfer tool relative to said templet and relative movement of said transfer tool continuously axially toward and into said template during winding movement of said wire guiding device, and hence during the whole winding process of a coil, said templet having an axially extending untapered surface portion onto which the wire coming from said wire-guiding device is placed such that all the turns of a coil are accumulated on the templet before removal from it.
Claim 3
Dependent Claim
17 words
Apparatus as claimed in claim 1 wherein said transfer tool is axially fixed during the winding process.
Claim 4
Dependent Claim
18 words
Apparatus as claimed in claim 1 wherein said wire guiding device is axially fixed during the winding process.
Claim 5
Dependent Claim
52 words
Apparatus as claimed in claim 1 wherein said transfer tool and said wire guiding device are relatively fixed at a predetermined axial distance from each other during at least a substantial porTion of the winding process, and together continuously move axially relative to said templet during said portion of the winding process.
Claim 6
Dependent Claim
42 words
Apparatus as claimed in claim 4 wherein said wire guiding device and said transfer tool are axially fixed, and said templet is moved axially from said wire guiding device onto said transfer tool continuously during the whole winding process of a coil.
Claim 7
Dependent Claim
22 words
Apparatus as claimed in claim 1 wherein said transfer tool is a drawing-in tool for drawing wire coils directly into a stator.
Claim 8
Dependent Claim
118 words
Apparatus as claimed in claim 1 further comprising a rotatable hollow drive shaft for said wire guiding device, a templet shaft passing coaxially through said hollow shaft and carrying said templet at one end, an exteriorly toothed gear mounted rotatably and eccentrically on said hollow shaft, a first interiorly toothed gear mounted non-rotatably on the apparatus and concentric with said hollow shaft and meshing with said exteriorly toothed gear, a second interiorly toothed gear mounted concentrically and non-rotatably on said templet shaft and meshing with said exteriorly toothed gear, and means connecting said hollow shaft and said wire guiding device with one another on the side of the templet shaft opposite the center of said exteriorly toothed gear.
Claim 9
Dependent Claim
92 words
Apparatus as claimed in claim 7 wherein the templet shaft end remote from the templet is journalled in and axially fixed to an axially shiftable and rotatably driveable machine part, and the winding wire is introduced into said machine part coaxially with but behind the end of said templet shaft, then radially outwardly and axially toward said hollow shaft, and then through said hollow shaft and through said wire guiding device, and wherein means are provided for rotatably driving said machine part and said hollow shaft in unison at the same speed.
Claim 10
Dependent Claim
43 words
Apparatus as claimed in claim 6 wherein said drawing-in tool is rotatable about its axis, and wherein a plurality of said drawing-in tools are mounted on a rotatable table for movement selectively to a plurality of said templets and to a drawing-in station.
Claim 11
Dependent Claim
49 words
Apparatus as claimed in claim 1 further comprising a stripper moveable across the complete wire coil accumulated on the template when the templet has moved relatively into the transfer tool for retaining the wire coil on the transfer tool upon relative withdrawal of the templet from the transfer tool.
Claim 12
Dependent Claim
52 words
Apparatus as claimed in claim 9 further comprising a wire clamping device disposed adjacent each template in a position to hold the wire during rotation of the drawing-in tool after stripping of a completed coil and during the beginning of the wind process for a further coil for the same drawing-in tool.
Claim 13
Dependent Claim
75 words
Apparatus as claimed in claim 9 further comprising a combined cutting and clamping device disposed adjacent each templet for cutting the wire after winding of the last coil to be suspended on a given drawing-in tool at a given position of the rotary table, and for clamping the supply end of the wire until the beginning of the winding process for the first coil of the coils to be transferred to a further drawing-in tool.
Claim 14
Dependent Claim
37 words
Apparatus as claimed in claim 1 wherein said wire guiding device is stopped in the same angle of rotation after each winding process to facilitate access of an operating member to an unlocking mechanism of said templet.
