Abstract

PURPOSE:To provide a banknote accumulating device requiring only a small mounting space with which residue of wavy matters after accumulation is not generated by forming wavy forms by an impeller instead of a conventional roller. CONSTITUTION:For accumulating banknotes, a supply motor 6 and a conveying motor 17 are actuated to convey the banknotes. When the banknote passes through between a gate roller 9 and a tension roller 11, outer parts of vanes of an impeller 12 are bent by the banknote. However, an outer diameter of the impeller 12 after the vanes are bent becomes larger than an outer diameter of the tension roller 11 because it is formed of easily deformed resilient matter. The banknote is formed wavy between the impeller 12 and an idler roller 2, and between a guide provided on the outer side of the impeller 12 and the impeller 12. In this condition, when a back end of the banknote passes through between the gate roller 9 and the tension roller 11, the impeller 12 pats the back end of the banknote to drop it to an accumulation part to be placed on a floor 15. A supply port and an accumulation port of the banknotes can be common.

When stacking the bills, as shown in FIG. 3, the feeding motor 6 and the conveying motor 17 are operated,
The banknotes are conveyed to the stacking section by the gate roller 1 and the feed roller 18. When the bill passes between the gate roller 1 and the tension roller 11, the outer portion of the blade of the impeller 12 is folded by the bill. However, since the outer diameter of the impeller 12 after the blades are bent is larger than the outer diameter of the tension roller 11, as shown in FIG. 5, the banknote 20 includes the impeller 12 and the idler roller 2. A corrugated shape is formed between the impeller 12 and the guide 19 provided outside the impeller 12.

In this state, when the rear end of the bill 20 passes between the gate roller 1 and the tension roller 11,
The impeller 12 strikes the rear end of the banknote 20 to drop the banknote 20 into the stacking unit and stack it on the floor 15. Floor 15
Is lowered by the floor lifting motor 16 via the belt 14 so that the space above the banknotes stacked thereon has a predetermined height.

When ejecting the bills, as shown in FIG. 4, the floor raising / lowering motor 16 raises the floor 15 via the belt 14, and the uppermost bill of the bills stacked on the floor 15 is picked up by the pickup roller 3. To a predetermined pressure. The pressing force of the bill against the pickup roller 3 is detected by the sensor 13 and detected by the floor lifting motor 1
Stop 6

When the feeding motor 6 is operated in this state, the pick-up roller 3 is rotated and the bills in contact are fed and conveyed between the gate roller 1 and the feed roller 18, and the gate roller 1 and the feed roller 18 are fed. Discharges the conveyed banknotes to the outside. At this time, when two or more banknotes are fed out at the same time, the second and subsequent banknotes are returned to the stacking unit by the gate roller 9, so that only the uppermost one banknote is discharged.

When ejecting bills, the impeller 12
Is retracted to a position outside the bill discharge path.

[0025]

As described above, in the banknote stacking apparatus of the present invention, the blade portion of the impeller is formed of an elastic body so that it can be easily deformed, and the diameter of the impeller is made larger than the diameter of the tension roller. Then, the bill is formed in a corrugated shape between the impeller and the idler roller, and between the guide provided on the outside of the impeller and the impeller, so that the mounting space is reduced and the bill feeding port is formed. The effect is that it can be shared with the collection port. Moreover, since the corrugated shape is formed by the elastic body, there is an effect that the corrugated shape can be prevented from remaining after being accumulated in the accumulating portion.
