Teller cash recycler
The present disclosure provides a teller cash recycler. The teller cash recycler includes a vault unit configured to store bills; a handling unit, provided at an upper portion of the vault unit, movable to a front side and a rear side of the vault unit, through which bills are deposited and withdrawn; a driving gear unit, provided at a lower portion of the handling unit, including a plurality of driving gears; a driven gear unit, provided at the upper portion of the vault unit, including a plurality of driven gears to which a driving force from the driving gears is transmitted; one or more swing arms, at which at least one of the driven gears is installed, configured to rotate by movement of the handling unit; and an interference unit, provided at the swing arm, configured to apply a rotational moment to the swing arm while being pushed by a handling unit.
1. A teller cash recycler comprising:
a vault unit configured to store bills;
a handling unit, provided at an upper portion of the vault unit, movable to a front side and a rear side of the vault unit, through which bills are deposited and withdrawn;
a driving gear unit, provided at a lower portion of the handling unit, including a plurality of driving gears;
a driven gear unit, provided at the upper portion of the vault unit, including a plurality of driven gears to which a driving force from the driving gears is transmitted;
a swing arm, at which at least one of the driven gears is installed, configured to rotate by movement of the handling unit; and
an interference unit, provided at the swing arm, configured to apply a rotational moment to the swing arm while being pushed by a part of the handling unit.
2. The teller cash recycler of claim 1 , wherein the swing arm has a first state in which the driven gear is in contact with the driving gear and thus a driving force from the driving gear is transmitted to the driven gear and a second state in which the contact between the driven gear and the driving gear is released.
3. The teller cash recycler of claim 1 , wherein the interference unit is fixed to an end portion of the swing arm via the driven gear and includes a stopper having an outer diameter greater than an outer diameter of the driven gear in order to avoid collision between the driven gear and the handling unit.
4. The teller cash recycler of claim 2 , wherein the swing arm rotates to the first state or the second state by an elastic spring when the handling unit moves to a front side or a rear side of the vault unit.
5. The teller cash recycler of claim 3 , wherein the driving gear and the driven gear are configured as helical gears having twisted threads to be engaged with each other.
6. The teller cash recycler of claim 1 , wherein the driving gears are provided at different heights at a lower portion of the driving gear unit.
7. The teller cash recycler of claim 6 , wherein the driving gears include:
a first driving gear projecting from the lower portion of the handling unit; and
one or more second driving gears, projecting from the lower portion of the handling unit by a height smaller than a height of the first driving gear, of which positions are close to a front side of the vault unit compared to a position of the first driving gear.
8. The teller cash recycler of claim 7 , wherein the driven gear includes:
a first driven gear to which a driving force from the first driving gear is transmitted; and
one or more second driven gears, installed at the swing arm, to which a driving force from the second driving gear is transmitted.
9. The teller cash recycler of claim 1 , wherein the handling unit has a retreating groove into which the interference unit is inserted when the driving force is transmitted from the driving gears to the driven gears.
