US 6,826,980 B2 · Drive and control systems for high speed intermittent motion generations, control and applications

Abstract

The present invention seeks to provide a system for high speed intermittent motion. The system consists of one or more intermittent motion generators. Each motion generator consists of a first and a second drive system with each drive system having its own control software and control input information received from a programmable logic controller (PLC). Each motion generator employs dual cams with fixed angular rotation. The dual cam combination consists of a first cam nested within a second cam. The dual cams permit independent and individual motion generation for each motion generator. The angular rotation of the second cam relative to the angular rotation of the first cam causes a linear displacement which generates intermittent linear motion for each individual motion generator.

Claims6

Dependent claims

A system for intermittent motion generation for a cam follower, the system including:

(a) a first cam coupled to a first driving means, the first cam rotating about a first fixed axis;
(b) a second cam coupled to a second driving means, the second cam rotating about a second axis, the second cam having a cam-shaped cavity with the first cam being concentrically nested within the cavity such that the first cam is rotatable about an inner cam-shaped surface of the cam-shaped cavity and the first cam is completely surrounded by the second cam;
(c) a cam follower having one end in contact with the second cam, the cam follower being linearly displaced due to an intermittent linear motion generated by a rotation of the second cam relative to a rotation of the first cam.
