Device for handling data media in a storage device
A robotic unit with a picker ( 18 ) serves for handling data media in a storage device. The robotic unit can be traversed with a base plate ( 24 ) on a guide bar ( 16 ). On the base plate ( 24 ) a rotary plate ( 28 ) is disposed which can be turned about a vertical axis. On the rotary plate ( 28 ) two motors ( 52, 56 ) are disposed, each of which causes, via a toothed wheel drive, the translational and the turning movement of the robotic unit. The toothed wheel drives ( 48, 50, 54, 58 ) are disposed in a common plane in an indented recess ( 46 ) of the base plate ( 24 ).
1. A device for handling data media in a storage device comprising:
slots for the data media, wherein the openings of said slots are disposed in the storage device in at least two groups offset at an angle with respect to one another; and
a robotic unit which can be traversed and positioned in front of the slots in order to remove the data media from the slots by means of a picker, to insert the data media into the slots, and to transport the data media between different slots;
wherein the robotic unit can be traversed by means of a toothed wheel driven by a first controllable motor and a toothed linear track along a translational path in a plane and can be turned by means of a second controllable motor engaging in a circular toothing about an axis of rotation perpendicular to the plane;
wherein the robotic unit comprises a base plate which can be displaced in a guided manner along the translational path;
wherein on the base plate a rotary plate is mounted in such a manner that it can turn about the axis of rotation perpendicular to the base plate;
wherein the rotary plate carries the picker;
wherein the base plate comprises, concentric to the axis of rotation, a recess within which a toothed wheel is accommodated which is mounted in such a manner that it can turn and is concentric with the axis of rotation;
wherein the first motor is disposed on the rotary plate and engages, by means of a pinion, in an outer toothing of the toothed wheel, wherein the outer toothing of the toothed wheel is in engagement with the toothed linear track;
wherein the second motor is disposed on the rotary plate and engages, by means of a pinion, in a circular toothing of the base plate; and
wherein said circular toothing is concentric to the toothed wheel.
2. The device according to claim 1 , wherein the recess of the base plate is formed to be circular and the circular toothing is formed as an inner toothing on the circumference of the recess.
3. The device according to claim 1 , wherein the outer toothing of the toothed wheel and the inner toothing of the recess are in a common plane.
4. The device according to claim 1 , wherein by driving only the first motor the robotic unit is moved translationally and by driving both the first motor and the second motor turning of the robotic unit about the axis of rotation can be combined with any translational movement of the robotic unit.
5. The device according to claim 1 , wherein the rotary plate carries a picker which can be adjusted in its height.
6. The device according to claim 5 , wherein the picker can be lowered to the rotary plate.
7. A device for handling data media in a storage device comprising:
