US 5,826,698 A · Apparatus for separating tangled coil springs

Abstract

A spring untangling apparatus for separating tangled coil springs comprises a box having spring inlet and outlet apertures at opposed walls thereof. A spring inlet duct is led to the spring inlet aperture. A vibration device is provided for vibrating the spring inlet duct to cause the tangled coil springs in the inlet duct to move toward the spring inlet aperture. The box is configured so that the tangled coil springs are placed in order so that clusters of the tangled coil springs are led into the box one cluster after another. An air jet nozzle is arranged for forcing the tangled coil springs into the box through the spring inlet aperture with an aid of compressed air, and another air jet nozzle is arranged for blowing up the tangled coil springs in the box to violently hit the same against inner walls of the box thereby untangling the same.

Dependent claims

A spring untangling apparatus for separating tangled coil springs, comprising:

a box having at least one collision wall;
first means for conveying the tangled coil springs into said box;
second means for controllably introducing the tangled coil springs in order into said box;
and
third means for hitting each cluster of the coil springs in the box against said collision wall to thereby untangle the same,
wherein said second means comprises:
a groove formed in a lower wall of said box, said groove extending in a direction from an inlet side of said box to an outlet side of said box, said groove being configured to align clusters of the tangled coil springs;
and
means for vibrating said lower wall of the box to convey said coil springs;
and
wherein said third means comprises at least one air jet nozzle from which a compressed air is injected into the box, said air jet nozzle being provided in said groove.
