Method and apparatus for winding ring cores, ring coils, ring core parts or ring coil parts

An apparatus for winding ring-like parts provided with ring openings with a winding material;

• comprising:
• winding material storage means including a supply roller means on which the winding material is wound and which is rotatable secured on a carrier means;
• said winding storage means having a counter coupling means;
• the winding material storage means being smaller than the ring opening of the part to be wound;
• means moving the winding material storage means about the part to be wound in such a manner that the winding material is wound off from the storage means and wound on said ring-like part;
• said means moving the winding storage means including at least two transfer means;
• each transfer means having a transfer coupling means;
• said transfer coupling means operable to engage with and disengage from the corresponding counter-coupling means of the winding material storage means;
• the moving means including means for moving the two transfer means in at least two coordinates;
• each transfer means operable to transport the winding material storage means along a part of the circumference of the part to be wound when moved by the moving transfer means;
• said transfer coupling means transferring the winding material storage means from one transfer means to the other transfer means at two different transfer places the means for moving the transfer means are operable to:
• (1) move the transfer means along one coordinate and oppositely from the one transfer place, (2) move the transfer means in the same direction along the other coordinate;
• and (3) being able to move the transfer means towards one another at the second transfer place;
• the transfer coupling means coupling one transfer means to the winding material storage means while decoupling the other transfer means therefrom at one transfer space while decoupling the material storage means from the one coupling mean and coupling the material storage means at the other transfer space;
• the coupling means coupling the material storage means to that transfer means which is being driven in the winding direction.

An apparatus for winding ring-like parts provided with a ring opening with a winding material, comprising:

• winding material storage means for initially storing the winding material;
• means subsequently moving the winding material storage means about the core part so as to wind-off the winding material from the storage means and winding the same on the ring-like part;
• the winding material storage means having dimensions smaller than the ring opening in the ring-like part and being operable to be moved through the ring opening as a structural unit;
• means for moving the winding material storage means about the part to be wound including first transfer means and second transfer means;
• means for alternately transferring the storage means from the first transfer means to the second transfer means;
• the means for moving the winding storage means including:
• a first means for moving the transfer means toward one another, a means for actuating the means for alternately transferring the winding material storage means at a first transfer place from the first to the second transfer means, subsequent moving means for subsequently moving the transfer means away from one another while the second transfer means carrying the winding material storage means is moved in the winding direction at a distance from the part to be wound;
• the winding material storage means rolling off along the part to be wound and to wind the winding material from off the winding material storage means and onto the part to be wound;
• further moving means for moving the first transfer means at the same time opposite the winding direction toward the second transfer place;
• subsequent moving means moving both transfer means to approach one another in a second transfer place;
• second actuating means for actuating the means for alternately transferring the winding material storage means to the first transfer means in the second transfer place, additional moving means to move the first transfer means in the winding direction at a distance to the part to be wound in such a manner that the winding material storage means continues to roll off along the ring-like part and the winding material is thereby continued to be wound off from the winding material storage means and wound on the part to be wound;
• and last moving means for moving the second transfer means simultaneously opposite the winding direction along the part to be wound toward the first transfer place.

An arrangement for winding ring devices having an opening with a winding material, a winding material storage unit means having a storage roller with winding material wound thereon and which is smaller than said opening in the ring device;

• two transfer means that are arranged on a joint axial line at a distance from one another and means for rigidly connecting the winding material storage unit to the two transfer means alternately;
• means for changing the position of the joint axial line from a position in which the line is located inside the ring device to a position in which the line is located outside the ring device to wind the winding material on the ring device by the alternating guiding of the winding material storage unit by one or the other of the two transfer means with the changing of the position of the line from inside to outside the ring device;
• the winding core storage unit always rigidly connected with one of the transfer means;
• means to move both transfer mechanisms toward one another to transfer places when the axial line extends inside or outside the ring device;
• and whereat one transfer means is connected to the winding material storage unit while the other transfer mechanism is disconnected from the winding material storage unit;
• the winding material storage unit roller being tangential with respect to a place on the ring device to wound;
• and means for rotating the ring device around its central axis.
