Abstract
An improved cash box system for a bill validator (11) which includes bill inlet (16) a sensor (OS) associated with the opening, a bill transporting assembly (21) and a bill stacking assembly (30). A cash box (10) associated with the bill validator (11) receives bills (B) from the bill stacking assembly (30) when the stacker motor (M2) is activated. A processing system (100) measures the current draw of the stacker motor (M2) and compares it to a predetermined limit of the current draw to determine whether the cash box (10) is full, when a bill is placed in the bill inlet.
Claims7
A bill validator having an improved cash box system comprising:
- a bill validator including a bill inlet opening and a sensor means associated with the said opening, a bill transport means including an electric motor for transporting a bill to a bill stacking position and a bill stacker means including an electric motor and means for moving the bill from the bill stacking position;
- a cash box associated with the bill validator and selectively receiving bills from the bill stacker means;
- and
- processing means including measuring means for measuring the current draw of the stacker motor, comparator means for comparing said current draw with a predetermined limit of the current draw, means to permit stacking when said limit is not exceeded and means for setting a fill status condition to selectively prevent stacking when said limit is exceeded,
- the improvement comprising:
- means for repeatedly determining the full status condition by cycling the stacker motor each time the inlet sensor detects a bill in the inlet and the status condition is set to fill.
An improved method of determining the cash box full condition in a bill validator having a bill receiving opening, bill transporting and stacking motors and a cash box the method comprising the steps of:
- placing a bill in a bill receiving inlet;
- detecting the presence of the bill and sending a signal to the bill stacker motor;
- comparing the current draw of the stacker motor with a predetermined limit of the current draw;
- accepting the bill when the limit is not exceeded, transporting the bill to a stacking position and stacking the bill in the cash box, and
- setting the cash box fill condition to prevent stacking when said limit is exceeded,
- the improved method comprising:
- repeatedly determining the full status condition by cycling the stacker motor each time a bill is placed in the inlet and the status condition is set to full.
A bill validator having an improved cash box system comprising:
- a bill validator including a bill inlet opening and a sensor means associated with the said opening, a bill transport means including an electric motor for transporting a bill to a bill stacking position and a bill stacker means including an electric motor and means for moving the bill from the bill stacking position;
- a cash box associated with the bill validator and selectively receiving bills from the bill stacker means;
- and
- processing means including measuring means for measuring a motor current characteristic of the stacker motor, comparator means for comparing said characteristic with a predetermined limit of said characteristic, means to permit stacking when said limit is not exceeded and means for setting a full status condition to selectively prevent stacking when said limit is exceeded,
- the improvement comprising:
- means for repeatedly determining the full status condition by cycling the stacker motor each time the inlet sensor detects a bill in the inlet and the status condition is set to full.
