Abstract

Documents or other items, such as paper cards, magnetic cards, magnetic tape, etc., driven by an intermittent motion imparting device (IMID), are subjected to accelerations and decelerations during each cycle of the IMID device. To minimize these effects an inertia roller has been utilized to produce a "flywheel" effect. The device consists of two pressure rollers (only one of which is shown), an inertia roller, and the IMID device.

Intermittent Motion Imparting Device With a Self Driven Inertia Roller

Documents or other items, such as paper cards, magnetic cards, magnetic tape, etc., driven by an intermittent motion imparting device (IMID), are subjected to accelerations and decelerations during each cycle of the IMID device. To minimize these effects an inertia roller has been utilized to produce a "flywheel" effect. The device consists of two pressure rollers (only one of which is shown), an inertia roller, and the IMID device.

The driven document is pinched between the pressure rollers and the inertia roller. The inertia roller is driven by the action of the IMID device on the driven document. The document is not allowed to decelerate rapidly under the influence of loads in the document path, because of the kinetic energy of the inertia roller. By limiting the magnitude of the decelerations and accelerations during each cycle of the tip or dot, which moves in an elliptical pattern, a number of improvements result.

These are improved efficiency of the IMID device, in that higher speeds are achieved for the same input power. More uniform velocity is obtained which may allow the IMID device to be used in applications requiring more accurate speed control. Significant acoustic improvement is made since the document is not being vibrated as severely. Less wear of the IMID elastomer dot or tip will result, because the document will not have to be accelerated during each cycle of the IMID.
