Arrangement for closing an opening for the output and/or input of notes of an automated teller machine
View Patent ↗The invention relates to an arrangement ( 10 ) for closing an opening for the input and/or output of notes of a device for handling notes. The arrangement ( 10 ) comprises a pivotable shutter element and a rotary solenoid. An armature of the rotary solenoid is connected to the shutter element via a connecting element. In a first position of the armature the shutter element is arranged in a closed position, and in a second position of the armature the shutter element is arranged in an open position.
1. An arrangement for closing an opening for the output and input of notes, of a device for handling notes, comprising:
a shutter element pivotable about an axis;
a rotary solenoid having an armature, the armature is rotatable about an axis of the armature; and
a connecting element through which the armature of the rotary solenoid is connected to the shutter element;
wherein:
in a first position of the armature, the shutter element is arranged in a closed position;
in a second position of the armature, the shutter element is arranged in an open position wherein when the armature rotates in an opening direction from the first position to the second position, the shutter element moves toward the open position;
a first end region of the connecting element is rotatably connected to the armature;
a second end region of the connecting element opposite to the first end region is rotatably connected to the shutter element;
the first end region is rotably connected to the armature via a first mounting element so as to be rotatable about a first axis of rotation spaced from the axis of the armature;
the second end region is connected to the shutter element via a second mounting element so as to be rotatable about a second axis of rotation spaced from the axis of the shutter element;
a first connecting line, which orthogonally intersects both the first axis of rotation and the axis of the armature, and a second connecting line, which orthogonally intersects both the first axis of rotation and the second axis of rotation, intersect one another at an angle (β) between 90° and 179° when the armature is arranged in the first position, which corresponds to the closed position of the shutter element;
a first stop element contacts the connecting element and prevents a rotary motion of the connecting element in a first direction of rotation when the armature is arranged in the first position, and a second stop element which contacts the shutter element and prevents a rotary motion of the shutter element in a second direction of rotation when the armature is arranged in the first position; and
the first direction of rotation is opposite to the second direction of rotation and; wherein when a force acts on the shutter element to urge the shutter element from the closed position toward the open position, said force urges the armature to rotate in a direction opposite to said opening direction.
2. The arrangement according to claim 1 , wherein, in the second position, the armature is rotated by an angle in the range between 60° and 70°, about its axis relative to the first position.
3. The arrangement according to claim 1 , wherein the rotary solenoid moves the shutter element from the closed position into the open position when the armature is moved from the first position into the second position.
4. The arrangement according to claim 1 , wherein the rotary solenoid is de-energized when the armature is arranged in the first position and is energized when the armature is arranged in the second position.
5. The arrangement according to claim 1 , wherein the rotary solenoid comprises at least one elastic element which holds the armature in the first position and which is elastically deformed when the armature is arranged in the second position.
6. The arrangement according to claim 1 , wherein the connecting element is a plate.
7. The arrangement according to claim 1 , wherein the first axis of rotation coincides with a rotational axis of the first mounting element and the second axis of rotation coincides with a rotational axis of the second mounting element.
8. The arrangement according to claim 1 , wherein a third connecting line, which orthogonally intersects both the second axis of rotation and the axis about which the shutter element is pivotable, and a second connecting line, which orthogonally intersects both the first axis of rotation and the second axis of rotation, intersect one another at an angle (α) between 90° and 180° when the armature is arranged in the first position.
9. The arrangement according to claim 1 , wherein a control unit is provided which controls application of electric current to the rotary solenoid.
10. The arrangement according to claim 9 , wherein the control unit controls the current applied to the rotary solenoid by pulse width modulation.
