Abstract

A method and apparatus are disclosed for removing one item of media at a time from an item of media container. The apparatus includes a movable element locatable in an abutting relationship with an elected item of media in a media container and disposed to a vibrating against the elected item of media to permit the elected item of media to be subsequently be removed alone from the container by a pick arm lever.

First claim

What is claimed is:

1. Apparatus for removing one item of media at a time from an item of media container, the apparatus comprising:
a gear;
a carrier affixed to the gear, wherein the gear is adapted to rotate the carrier in a clockwise and anti-clockwise motion about an axis of rotation, wherein the carrier is adapted to perform rotational motion about the axis of rotation;
a pick arm lever having an abutment surface affixed to the carrier, wherein rotation of the gear in a first direction rotates an end of the pick arm lever into an abutting relationship with an elected item of media in a media container and wherein the pick arm lever vibrates against a bunch of items of media that includes the elected item of media to detach the elected item of media for picking by the pick arm lever through a vacuum source so that only the elected item of media can be subsequently removed alone from the container by terminating the vacuum source and removing the elected items by rollers, wherein the pick arm lever is an elongated arm that is fixedly connected on a further end off center on the carrier, and wherein the gear moves with the pick arm lever and the carrier by moving the abutment surface forward and backward against an outer surface of the elected item at a frequency of 90-110 HZ;
wherein the rollers include an upper nip roller that are constantly driven in a clockwise direction and a lower nip roller that are constantly driven in an anti-clockwise direction, wherein diameters of the upper nip roller and the lower nip roller are different, and wherein the upper nip roller is driven at a different speed in the clockwise direction from the lower nip roller being driven in the anti-clockwise direction, and wherein the lower nip roller is a partial truncated roller that is not a whole roller;
wherein the gear, the carrier, and the pick arm lever are separate parts that are connected together and to the pick arm lever and combined with the upper nip roller and the lower nip roller to form a pick unit positioned adjacent to the media container with the gear, the carrier, and the pick arm lever all rotated together in the clockwise direction or the anticlockwise direction about the axis of rotation by a pick motor.

2. The apparatus as claimed in claim 1 , wherein said end of the pick arm lever is locatable responsive to a drive signal to the pick motor from a controller.

3. The apparatus as claimed in claim 1 , wherein:
in a release mode of operation, said abutment surface of the pick arm lever is located off center on the carrier whereby repeated counter rotation of the carrier induces an effective backwards and forwards motion of the end of the pick arm lever against the elected item of media.

4. The apparatus as claimed in claim 3 , wherein:
in a pick mode of operation, immediately subsequent to said release mode of operation, said carrier is rotated about the axis of rotation responsive to a drive signal from a controller to thereby urge a suction element carried by the end of the pick arm lever against an outer surface of said elected item of media.

5. The apparatus as claimed in claim 1 , further comprising:
said apparatus comprises an automated teller machine (ATM), said item of media comprises a currency note and said container comprises a currency cassette.

6. A method of removing one item of media at a time from an item of media container, the method comprising:
prior to a pick mode of operation in which an elected item of media is removed alone from an item of media container, repeatedly rotating a gear-driven carrier of an abutment surface having a pick arm lever moving the abutment surface forward and backward against the elected item of media at a frequency of 90-110 HZ, in a clockwise and anti-clockwise motion about an axis of rotation and inducing motion of the end of the pick arm lever, responsive to the repeated rotation, to thereby only separating said elected item of media from a next item of media with a vacuum source and terminating the vacuum source to release the elected item of media to rollers for removal, and wherein the pick arm lever is an elongated arm that is fixedly connected on a further end off center on the gear-driven carrier, and wherein a gear of the gear-driven carrier moves with the pick arm lever and the carrier, wherein the gear-driven carries urges the carrier to perform rotational motion about the axis of the rotation;
constantly rotating an upper nip roller having a first diameter in clockwise direction at a first speed while constantly rotating a lower nip roller having a second and different diameter from the first diameter in an anti-clockwise direction at a second different speed from the first speed of rotation, wherein the lower nip roller is a partial truncated roller that is not a whole roller; and
operating the gear, the gear-driven carrier, and the the pick are lever as separate parts that are connected together and connected to the pick arm lever with the upper nip roller and the lower nip roller to form a pick unit that is positioned adjacent to the media container with the gear, the carrier, and the pick arm lever all rotated together in the clockwise direction or the anticlockwise direction about the axis of rotation by a pick motor.

7. The method as claimed in claim 6 , further comprising the steps of:
in the pick mode of operation immediately subsequent to a release mode of operation, providing a signal;
rotating the gear-driven carrier of the pick arm lever about an axis of rotation responsive to the signal;
urging a suction element carried by the end of the pick arm lever against the elected item of media;
securing the item of media to the suction element; and
removing the item of media from the item of media container by rotating the carrier of the pick arm lever about the axis of rotation into a feed location, a portion of said item of media being carried with the suction element.

8. A product which comprises a computer program comprising program instructions for:
prior to a pick mode of operation in which an elected item of media is removed alone from an item of media container, repeatedly rotating a gear-driven carrier of an abutment surface having a pick arm lever through movement of a gear of the gear-driven carrier that moves with the pick arm lever and the gear-driven carrier and moving the abutment surface forward and backward against the elected item of media at a frequency of 90-110 HZ, in a clockwise and anti-clockwise motion about an axis of rotation and inducing motion of the end of the pick arm lever and the abutment surface, wherein the gear-driven carrier performs rotational motion about the axis of rotation;
responsive to the repeated rotation, to thereby only separating said elected item of media from a next item of media with a vacuum source and terminating the vacuum source to release the elected media item to rollers for removal, wherein the pick arm lever is an elongated arm that is fixedly connected on a further end off center on the gear-driven carrier;
constantly rotating an upper nip roller having a first diameter in clockwise direction at a first speed while constantly rotating a lower nip roller having a second and different diameter from the first diameter in an anti-clockwise direction at a second different speed from the first speed of rotation, wherein the lower nip roller is a partial truncated roller that is not a whole roller; and
operating the gear, the gear-driven carrier, and the pick arm lever as separate parts that are connected together and combined with the upper nip roller and the lower nip roller to form a pick unit positioned adjacent to the media container with the gear, the carrier, and the pick arm lever all rotated together in the clockwise direc
