Abstract

A banknote stacking device includes a piece-by-piece banknote conveying mechanism, an upper conveyor belt, an arc-shaped stacking plate, a movable blocking mechanism, a sensor device, and a control unit. An elastic sheet is arranged on the arc-shaped stacking plate at a position for stacking banknotes, an end of the elastic sheet is fixed on the arc-shaped stacking plate, and a free end of the elastic sheet extends in a direction opposite to the conveying direction of the banknotes, the extending segment of the elastic sheet forms an arch and is configured to elastically support the upper conveyor belt, and a through-groove is provided in the arc-shaped stacking plate at a position corresponding to the elastic sheet, and the free end of the elastic sheet is configured to extend and retract freely in the through-groove.

First claim

The invention claimed is:

1. A banknote stacking device, comprising:
a piece-by-piece banknote conveying mechanism configured to convey a single sheet of banknote;
an upper conveyor belt configured to provide a driving force to the banknote and arranged around a driving wheel, driven wheels and a pinch roller which are arranged in a conveying direction of the banknote;
an arc-shaped stacking plate configured to support the banknote, wherein the upper conveyor belt fitting closely to an arc-shaped surface of the arc-shaped stacking plate to define a conveying passage for the banknote, a length of the conveying passage is at least greater than a length of one sheet of the banknote in the conveying direction, and one end of the conveying passage abuts the piece-by-piece banknote conveying mechanism and is slightly lower than a delivering outlet of the conveying mechanism, and another end of the conveying passage forms a discharging port for a whole stack of banknotes;
a movable blocking mechanism arranged on a section of the conveying passage close to the discharging port and configured to selectively block the banknote;
a sensor device arranged at a tail end of the delivering outlet of the piece-by-piece banknote conveying mechanism and configured to detect the arrival and passing of a sheet of the banknote; and
a control unit configured to control the upper conveyor belt to move or stop moving according to information feedback from the sensor device;
wherein, an elastic sheet is arranged on the arc-shaped stacking plate at a position for stacking banknotes, an end of the elastic sheet is fixed on the arc-shaped stacking plate, and a free end of the elastic sheet extends in a direction opposite to the conveying direction of the banknotes, the extending segment of the elastic sheet forms an arch and is configured to elastically support the upper conveyor belt, and a through-groove is provided in the arc-shaped stacking plate at a position corresponding to the elastic sheet, and the free end of the elastic sheet is configured to extend and retract freely in the through-groove.

2. The banknote stacking device according to claim 1 , wherein the arc-shaped stacking plate comprises three sections, a section near the piece-by-piece banknote conveying mechanism forms a rear arc-shaped plate, a section near the discharging outlet forms a front arc-shaped plate, and a middle section forms a direction reversing device, wherein, the elastic sheet is arranged on the front arc-shaped plate, and an end of the rear arc-shaped plate close to the front arc-shaped plate tilts upward to be higher than a surface of the front arc-shaped plate to form a height difference.

3. The banknote stacking device according to claim 2 , wherein at least one pair of convex ribs are formed on the surface of the rear arc-shaped plate at two sides of the upper conveyor belt, and a distance between the pair of convex ribs is smaller than the minimum dimension of the banknote in a direction perpendicular to the conveying direction.

4. The banknote stacking device according to claim 3 , wherein a floating pinch roller is provided on a side, away from the arc-shaped plate, of the upper conveyor belt at a position corresponding to the convex ribs, and is configured to increase a conveying force of the upper conveyor belt to the banknote.

5. The banknote stacking device according to claim 2 , wherein a recycling conveyor belt assembly and a discharging conveyor belt assembly are arranged below the direction reversing device and the front arc-shaped plate, wherein at least a section of the recycling conveyor belt assembly fits with a section of the discharging conveyor belt assembly to form a recycling conveying passage for the banknote.
