Abstract

An apparatus for automatically aligning bills includes: a plurality of skew control units including a driving roller unit, a body, a first gear unit, and a second gear unit; a first motor unit connected with the first gear unit through a first power transmission member and providing a driving force to the driving roller unit; a second motor unit connected with the second gear unit through a second power transmission member and providing torque to the body; and ball caster units having a spherical shape and coming in contact with a second side of the bill.

First claim

What is claimed is:

1. An apparatus for automatically aligning bills, comprising:
a plurality of skew control units including a driving roller unit moving a bill in contact with a first side of the bill, a body rotatably supporting the driving roller unit and being rotatable about a rotary shaft to change a conveying direction of the bill, a first gear unit disposed on a first side of the body and providing a driving force to the driving roller unit, and a second gear unit disposed on a second side of the body and correcting skew of the bill by rotating the body;
a first motor unit connected with the first gear unit through a first power transmission member and providing a driving force to the driving roller unit;
a second motor unit connected with the second gear unit through a second power transmission member and providing torque to the body; and
ball caster units having a spherical shape and coming in contact with a second side of the bill wherein the first motor unit provides a driving force to a first driving shaft through a first bevel gear, and
wherein a first driving gear unit connected with the first power transmission member is disposed on the first driving shaft.

2. The apparatus of claim 1 , wherein the first gear unit includes:
a main gear receiving a driving force from the first power transmission member;
a bevel ring gear integrally coupled to a top of the main gear; and
a bevel pinion gear engaged with a side of the bevel ring gear, receiving torque from the bevel ring gear, disposed on a same shaft with the driving roller unit, and rotating the driving roller unit.

3. The apparatus of claim 1 , wherein a bearing is disposed between the first gear unit and the first side of the body.

4. The apparatus of claim 1 , wherein the second motor unit provides a driving force to a second driving shaft through a second bevel gear, and
a second driving gear unit connected with the second power transmission member is disposed on the second driving shaft.

5. The apparatus of claim 1 , wherein the first power transmission member and the second power transmission members are timing belts.

6. The apparatus of claim 5 , wherein a tensioner for maintaining tension is disposed on the first power transmission member and the second power transmission member.

7. The apparatus of claim 1 , wherein the ball caster units each include:
a spherical ball; and
a housing holding the ball by covering a portion of the ball so that the ball makes a spherical motion at a predetermined position without separation.

8. The apparatus of claim 7 , wherein the ball caster units each further include an elastic member for pushing the ball to the driving roller unit to increase a force for holding the bill.
