Abstract

Claims (54)

1. A currency picking system for an Automated Teller Machine, ATM, comprising:

a) a pick-up member ( 26 ) which

i) is attached to, and rotates with, a driven gear ( 30 ),

ii) supports vacuum cups ( 28 ) which grasp banknotes,

b) a rotatable member ( 52 );

c) a first linkage, driven by the rotatable member ( 52 ), which rotates the driven gear ( 30 ) and the pick-up member ( 26 ) alternately between

i) a pick up position, wherein banknotes are picked from a supply, and

ii) a release position;

d) a second linkage, driven by the rotatable member ( 52 ), which induces a pump ( 18 ) to

i) apply vacuum to the vacuum cups ( 28 ) when at the pick position, and

ii) reduce vacuum applied to the vacuum cups ( 28 ) when at the release position.

2. System according to claim 1 , wherein no valves are used in application of, or reduction of, the vacuum.

3. System according to claim 1 , wherein the first linkage comprises:

i) a cam track ( 62 ) on the rotatable member ( 52 ), which rotates when the rotatable member ( 52 ) rotates;

ii) a cam roller ( 64 ) which follows the cam track ( 62 ) when the rotatable member ( 48 ) rotates;

iii) a drive arm ( 40 ) connected to the cam roller ( 64 ), such that movement of the cam roller ( 64 ) along the cam track ( 62 ) causes the drive arm ( 40 ) to pivot between first and second positions about a pivot point ( 68 ),

iv) a drive gear ( 66 ) attached to the drive arm ( 40 ), which drive gear ( 66 ) pivots about the pivot point ( 68 ) when the drive arm ( 40 ) pivots, and which drives the driven gear ( 30 ).

4. System according to claim 1 , wherein the second linkage comprises:

i) a drive rod ( 46 ) driven by the rotatable member ( 52 );

ii) a pump ( 18 ) connected to the drive rod ( 46 ); and

iii) tubes ( 20 , 22 ) connecting between the pump ( 18 ) and the suction cups ( 28 ),

wherein (A) the pump ( 18 ) applies suction to the vacuum cups ( 28 ) when the pick-up member ( 26 ) is in the pick up position and (B) the pump ( 18 ) reduces suction when the pick-up member ( 26 ) is in the release position.

5. System according to claim 4 , wherein the rotatable member ( 52 ) comprises a gear, the cam track ( 62 ) is located on one side of the gear, and the drive rod ( 46 ) is pivotally connected to the gear on its other side.

6. A picking system for an Automated Teller Machine, ATM, comprising:

a) a rotatable member ( 52 );

b) a conversion system which converts rotary motion of the rotatable member ( 52 ) into oscillatory motion of a drive gear ( 66 );

c) a driven gear ( 30 ), driven by the drive gear ( 66 );

d) a pick-up member ( 26 ) which

i) is attached to the driven gear ( 30 ),

ii) supports vacuum cups ( 28 ) which pick banknotes,

iii) is induced by the oscillatory motion to rotate between

A) a pick up position, wherein banknotes are picked up from a cassette, and

B) a release position;

e) a pump ( 18 ), linked to a crank ( 54 ) on the rotatable member ( 52 ), which

i) applies vacuum to the vacuum cups when the pick-up member ( 26 ) is in the pick up position, and

ii) reduces vacuum when the pick-up member is in the release position.

7. A system according to claim 6 , wherein the conversion system comprises:

i) a cam track ( 62 ) on the rotatable member ( 52 ), which rotates when the rotatable member ( 52 ) rotates;

ii) a cam roller ( 64 ) which follows the cam track ( 62 ) when the rotatable member ( 48 ) rotates;

iii) a drive arm ( 40 ) connected to the cam roller ( 64 ), such that movement of the cam roller ( 64 ) along the cam track ( 62 ) causes the drive arm ( 40 ) to pivot between first and second positions about a pivot point ( 68 ),

wherein the drive gear ( 66 ) is attached to the drive arm ( 40 ), and pivots about the pivot point ( 68 ) when the drive arm ( 40 ) pivots.

8. An Automated Teller Machine, ATM, comprising:

a) a first picking system, which uses vacuum cups to grasp banknotes, wherein a single first source of mechanical power

i) moves a first currency picker to a pick up position at a first supply of banknotes;

ii) induces a stroke in a first piston pump, to create vacuum in the first picker;

iii) moves the first picker to a first release position; and

iv) induces a release stroke in the first piston pump, to reduce vacuum in the first picker; and

b) a second picking system, which uses vacuum cups to grasp banknotes, wherein a single second source of mechanical power

i) moves a second currency picker to a pick up position at a second supply of banknotes;

ii) induces a stroke in a second piston pump, to create vacuum in the second picker;

iii) moves the second picker to a second release position; and

iv) induces a release stroke in the second piston pump, to reduce vacuum in the second picker,

wherein the first picking system handles banknotes of one denomination, and the second picking system handles sheets different from said banknotes of one denomination.

9. ATM according to claim 8 , wherein the sheets different from said banknotes of one denomination comprise banknotes of a different denomination.
