Abstract
A collision-proof spring transfer takes place in the process, which comprises a continuous transfer of coil springs from the pipeline through an exit opening of the pipeline into assigned spring receptacles, and an automatic prevention of any re-entry of coil springs that have passed through the exit opening in the direction of the spring receptacle and rebound from the region of the spring receptacle back into the pipeline.
Claims20
A method of producing coil springs from wire comprising:
- conveying wire from a wire reserve to a numerically controlled spring coiling machine;
- successively forming portions of the wire in the spring coiling machine to coil springs in a forming operation;
- severing each coil spring after the forming operation from the supplied wire;
- and
- successively transporting severed coil springs through a pipeline of a pneumatic conveyor system into a spring receptacle of a downstream machine,
- wherein the successively transporting comprises a collision-proof spring transfer comprising continuously transferring coil springs from the pipeline through an exit opening of the pipeline into assigned spring receptacles, and automatically preventing re-entry of coil springs that have passed through the exit opening in the direction of the spring receptacle and rebound from the region of the spring receptacle back into the pipeline.

A system that produces coil springs from wire comprising:
- a spring coiling machine having a infeed device for conveying a wire to a forming installation which has forming tools for forming the wire to a coil spring, and having a cutting installation for severing a coil spring from the supplied wire after completion of a forming operation;
- a pneumatic conveyor system having a pipeline successively transporting severed coil springs from the spring coiling machine to the downstream machine,
- wherein a feeding installation for pressurized fluid to accelerate the coil springs in the transport direction is disposed behind an inlet opening of the pipeline, and an exit opening dispenses the coil springs into assigned spring receptacles is disposed on an exit side of the pipeline, and
- a collision-proof spring transfer system configured for a continuous transfer of coil springs from the pipeline through an exit opening of the pipeline into assigned spring receptacles, and automatically preventing any re-entry of coil springs that have passed through the exit opening in the direction of the spring receptacle and rebound from the region of the spring receptacle back into the pipeline.
