Abstract
Abstract For assembling wound coils into stator grooves, an apparatus for transporting transfer tools between different stations including a winding station whereat the transfer tools receive wound coils and drawing-in stations whereat the coils on the transfer tools are drawn into the stator grooves. A plurality of transport carriages, each having a transport tool thereon, are moved along a rail in a closed path to the various stations. The size and shape of the path can be varied. Each transport carriage can stop or move along the path independently of the other transport carriages.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
165 words
An apparatus for assembling coils onto stators of electric machines or the like comprising, a guide rail arranged in the form of a closed path, a plurality of transport carriages mounted on said guide rail for movement along said path, a transfer tool on each said transport carriage, each said tool including a means for holding groups of wound coils and a stator core, at least one coil winding machine adjacent said path and including a winding device for winding coils to be placed onto the transfer tool as the latter passes through the winding station, at least one drawing-in station adjacent said path and including a drawing-in device for drawing wound coils arranged on a given transfer tool into a stator coil also mounted on that transfer tool, and a drive means for driving the said transport carriages containing the transfer tools along said path such that each transport carriage can be moved therealong or stopped independently of the other of said transport carriages.
Claim 2
Independent Claim
165 words
An apparatus for assembling coils onto stators of electric machines or the like comprising, a guide rail arranged in the form of a closed path, a plurality of transport carriages mounted on said guide rail for movement along said path, a transfer tool on each said transport carriage, each said tool including a means for holding groups of wound coils and a stator core, at least one coil winding machine adjacent said path and including a winding device for winding coils to be placed onto the transfer tool as the latter passes through the winding station, at least one drawing-in station adjacent said path and including a drawing-in device for drawing wound coils arranged on a given transfer tool into a stator coil also mounted on that transfer tool, and a drive means for driving the said transport carriages containing the transfer tools along said path such that each transport carriage can be moved therealong or stopped independently of the other of said transport carriages.
Claim 3
Dependent Claim
48 words
An apparatus according to claim 1, wherein said guide rail is made up of a plurality of individual segments arranged to form said closed path, whereby the length and shape of the path can be varied by varying the number and arrangement of the segments forming said path.
Claim 4
Dependent Claim
23 words
An apparatus according to claim 1, including a plurality of coil winding stations and a plurality of drawing-in stations arranged along said path.
Claim 5
Dependent Claim
71 words
An apparatus according to claim 1, wherein said drive means comprises an endless, continuously moving driving member which follows the said closed path, individual drive elements on each said transport carriage and control means for causing each said driving element to either drivingly engage the driving member to be driven thereby along the path, or non-drivingly engage the said driving member such that its carriage is not driven along the path.
Claim 6
Dependent Claim
80 words
An apparatus according to claim 4, wherein each driving element comprises a rotating member continuously engaging the said driving member, and wherein the control means comprises a means for permitting the driving element to be rotated freely about its axis by the driving member whereby the driving element is not moved along said path or preventing rotation of the driving element about its axis whereby it and its transport carriage are moved along said path by the said driving member.
Claim 7
Dependent Claim
51 words
An apparatus according to claim 5, wherein the driving member is a chain, the driving elements are sprockets, the teeth of which continuously engage the chain, and wherein the control means comprises a friction clutch selectively engaging the said sprocket wheel to either permit or prevent rotation thereof about its axis.
Claim 8
Dependent Claim
20 words
An apparatus according to claim 4, including arresting means for positively locating and arresting the carriages at the said stations.
Claim 9
Dependent Claim
37 words
An apparatus according to claim 7, said arresting means including a bolt mounted on the rail at each station, and movable into a bore in a transport carriage located at that station to positively hold the same.
