Currency Cartridge

This is an apparatus and method for controlling the metering of documents within a sealed currency cartridge into a document transport by vibrating the cartridge.

The cartridge comprises three basic components: back plate 1, bottom 2, and top 3. Bottom 2 is molded with two recessed channels 4, with FIBRE-TRAN* strips 5 cemented into the channels. FIBRE-TRAN is a friction material with nylon fiber fingers oriented at 45 degrees from the substrate surface. Back plate 1 has two pads 6 which are serrated to coact with the FIBRE-TRAN in channels
4. Back plate guide lugs 7 coact with molded slot 8 to insure engagement between serrations 6 and FIBRE-TRAN 5.

Upon insertion into the document feeding mechanism, the cartridge engages resilient mount 9 and latches to solenoid driver 10. As cyclic pulses (approximately 60 CPS) are applied to driver 10, the entire cartridge vibrates. The inertia of back plate 1 will force it in a forward direction, whereas FIBRE- TRAN 5 will prevent backward motion of plate 1. The resultant metering action can be controlled by vibration amplitude, frequency, and duration. A pressure sensitive switch, not shown, can be utilized to sense the force on the bills at the exit end for vibration driver 10 control feedback. * Trademark of Minnesota Mining and Manufacturing Co.
