1. Field of the Invention
The invention relates to a climatic cabinet or storage cabinet with an upper zone and a lower zone, and storage positions for storing objects in one of the lower and upper zone.
2. Discussion of Background Information
With the increasing degree of automation in medical engineering, there is a rising need to be able to manage substances from long-term storage automatically. To avoid chemical changes in the substances, they are often stored at the lowest temperatures possible. The temperature ranges below −80° C. are of increasing importance here. The transport of storage articles at these extremely low temperatures makes special demands on the mechanics and control of a storage system.
Known systems use a transport robot that is arranged in a moveable manner in an aisle between shelves with drawers. The robot is able to pull out the drawers and remove the contents therefrom. The robot thereupon moves to a periphery at the end of the aisle. The robot thereby moves between the shelves only when access takes place. The region of the periphery has a higher temperature than the region of the racks.
Another system, which is described in U.S. Pat. No. 6,694,767, has cassettes arranged in a chest that can be drawn out vertically. A gripper removes the storage articles from the drawn-out container and transports them to the periphery. The upper region of the arrangement is warmer than the lower.
The disadvantage of the known systems is that either they are suitable exclusively for large storage facilities, or that they leave a large amount of space unused. Furthermore, with the known arrangements it is not easy to integrate processing devices in a space-saving manner while maintaining the footprint.
In a first aspect of the invention, a storage system is provided that is suitable for low temperatures and small devices. In accordance with the invention, a vertical transport mechanism is therefore provided, with which the objects can be transported between the lower—colder zone—and the upper—warmer zone. The objects are transported to a lock in a horizontal or tilted direction by a horizontal transport mechanism, which is located at least in part in the upper zone.
The vertical transport mechanism is preferably formed by a transport lifting device or a rotary elevator system.
The storage system presented is particularly suitable for small and medium storage sizes as well as storage systems with integrated processing devices. A good use of space and simple and cost-effective solutions for the transport mechanisms are of prime importance with systems of this size.

Other exemplary embodiments and advantages of the present invention may be ascertained by reviewing the present disclosure and the accompanying drawing.
The present invention is further described in the detailed description which follows, in reference to the noted plurality of drawings by way of non-limiting examples of exemplary embodiments of the present invention, in which like reference numerals represent similar parts throughout the several views of the drawings, and wherein:
The particulars shown herein are by way of example and for purposes of illustrative discussion of the embodiments of the present invention only and are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the present invention. In this regard, no attempt is made to show structural details of the present invention in more detail than is necessary for the fundamental understanding of the present invention, the description taken with the drawings making apparent to those skilled in the art how the several forms of the present invention may be embodied in practice.
In lower zone 10, the climatic cabinet forms a cooling vat 14, in which a low temperature is maintained by a refrigeration unit 15. A low-temperature storage is thus rendered possible, while the components in upper zone 11 are exposed to temperatures that are not as low.
Upper zone 11 is covered by a cover 16 and is likewise cooled, albeit to a temperature that is not as low. A dryer 17 is provided in upper zone 11 to extract moisture from the atmosphere within the climatic cabinet to prevent the components from icing. Dryer 17 is a cooling device through which the air in the climatic cabinet is guided and in which the air is brought to a temperature that is lower than the temperature in the other parts of the device. Moisture is thus extracted from the air in a targeted manner and at a defined location.
Cassettes 12 rest on shelf-like supports 22 arranged next to one another, each support 22 being able to accommodate several, preferably at least three, cassettes 12 next to one another in a horizontal direction X, i.e., each support has room for a plurality of storage-positions next to one another and above one another. In the lower zone 10 several supports 22 are provided, arranged next to one another in a horizontal direction Y, the direction Y being perpendicular to the direction X.
Supports 22 are suspended in a manner displaceable in direction Y on guides 35 lying opposite one another on a supporting frame 21 of upper zone 11. The number of supports 22 is selected such that they fill the space available to them in the direction Y apart from a transport gap 25. By displacement of individual supports 22 in the direction Y, transport gap 25 can be formed in front of each of supports 22, so that the transport mechanism described later can access the storage positions in cassettes 12.
A lifting device 50 is suspended in upper zone 11. Lifting device 50 is arranged on supporting frame 21 so as to be horizontally moveable in direction Y along supports 22 by a longitudinal shift table 31 and in the direction X between supports 22 by a transverse shift table 41. Longitudinal shift table 31 is attached on longitudinal guides 32 to supporting frame 21 and can be moved in direction Y with a longitudinal shift drive 33. Transverse shift table 41 is attached to a transverse guide 42 on longitudinal shift table 31 and can be moved in direction X with a transverse shift drive 43.
Lifting device 50 supports a lift carriage 51 moveable in height. A rotary table 61, which can be pivoted about a vertical axis by a semirotary actuator 63, is arranged on lift carriage 51.
A transport scoop 74 horizontally moveable via a scoop drive 73 is arranged on rotary table 61. During the transport; a storage object 13 respectively lies on transport scoop 74.
For access to the storage articles, lifting device 50 is moved along supports 22 to transport gap 25. Lift carriage 51 can now be moved into transport gap 25 between supports 22 to the desired storage position for storage object 13. For longitudinal movement, the supports have an aisle 24 through which lift column 52 of transport lift 50 can be moved horizontally in direction Y.
Supports 22 are suspended on guides 35 in upper zone 11. A sliding device comprising a sleeve valve engine 23 and a slide sprocket 23a is provided in upper zone 11 to displace supports 22 in direction Y.
A lock (not shown in
A second exemplary embodiment of the climatic cabinet is shown in
Lifting device 50 is likewise attached to supporting frame 21 in upper zone 11 It has a vertical drive 53, a semirotary actuator 63 and a horizontal sliding device, driven by a scoop drive 73. A lift carriage 51 is supported on a lift column 52 and vertically moveable with the vertical drive 53. The traverse of the lift carriage 51 extends from the height of the rotary plate 29 to above supporting frame 21.
A lock 81 is provided on the vertical side wall in upper zone 11 of the climatic cabinet to allow objects 13 to be exchanged with the environment.
In a third exemplary embodiment, which is shown in
Lifting device 50 has a scoop 74, which can be pivoted about the carousel axis and moved vertically parallel to the carousel axis and extended horizontally. Scoop 74 is arranged on lift carriage 51.
To transport a storage object 13, lifting device 50 rotates with scoop 74 to cassette 12 in which the desired storage object is located. Lift carriage 51 moves to the tier of the cassette with the storage object. Scoop 74 is extended and the object 13 is loaded. Lift carriage 51 brings storage object 13 from lower zone 10 with cassettes 12 to upper zone 11 in which the automatically actuatable lock 81 is located.
In a fourth exemplary embodiment, which is shown in
As can be seen from
The rotary elevator system is suspended on supporting frame 21, which is arranged in upper zone 11. Furthermore, in upper zone 11 a pull-down claw 75 is provided, which can be moved over each transport path of rotary elevator 101. To this end, pull-down claw 75 is horizontally movable in direction X and Y. For access to a desired storage position, supporting platform 103 is brought to upper top point 104 of its transport path, and rotary elevator 101 is set in motion until the desired storage position is in top position 104. Pull-down claw 75 is positioned above supporting platform 103 so that storage object 13 can be picked up from storage platform 103 at top position 104 of the respective rotary elevator 101 and transported to lock 81, or vice versa.
For transport through lock 81, a deposit position 85 and a transfer position 86 are provided in the embodiment according to
Furthermore, in
In all of the exemplary embodiments described so far, the climatic cabinet is divided into a lower zone 10 and an upper zone 11, and a refrigerator 15 is provided, which makes it possible to maintain a much lower temperature in lower zone 10 than in upper zone 11. The temperature in lower zone 10 is preferably below −30° C., in particular approx. −80° C., while in upper zone 11 it is preferably above −30° C., e.g., −20° C., so that mechanical components, cable insulations, sensors, etc., still function without special measures.
Moreover, in lower zone 10 storage locations are provided for storing objects 13. For access to objects 13 at the storage positions in lower zone 10, a vertical transport mechanism is provided to enable vertically shifting objects 13 between lower zone 10 and upper zone 11. In the embodiments according to
Lock 81 and at least a part of a horizontal transport mechanism are provided in upper zone 11. The horizontal transport mechanism makes it possible to convey objects 13 in a horizontal or oblique direction between the vertical transport mechanism and lock 81. “Oblique direction” thereby means a direction with a horizontal component. If the vertical and horizontal transport mechanisms are formed at least in part by the some components, no explicit transfer of the object between vertical and horizontal transport mechanism need thereby occur.
In the embodiment according to
Another embodiment of the invention is shown in
As can be seen from
User door 110 is arranged at a processing device 91. It is extended at the top compared to the embodiment in
An arrangement with exactly one cassette or with two cassettes or with a larger number of cassettes is also conceivable.
In all of the embodiments shown so far, the cabinet has divided into two zones 10 and 11, in which a lower temperature prevails in lower zone 10 than in upper zone 11, makes it possible to store objects 13 at very low temperatures.
The same principle can also be applied for climatic cabinets in which objects 13 are stored at elevated temperature. In this case, however, the device shown so far must be inverted, such that the storage zone is formed by upper zone 11, while the lock opening 81 lies in lower zone 10. In this manner it is ensured that the warm air remains in the storage zone when lock opening 81 is opened. Very high temperatures (e.g., 100° C. and higher) can thereby also prevail in the upper zone, in particular when the guides and bearings of the moveable parts are arranged mainly in lower zone 10.
One example of a device of this type is illustrated in
As can be seen, lift column 52 in this case is supported on a longitudinal guide 32 in lower zone 10 and projects into upper zone 11. It supports lifting device 50 with rotary carriage 61. Lifting device 50 or lift column 52 is in turn horizontally displaceable, namely in direction Y as well as in direction X (where direction X is perpendicular to the drawing plane in
A heater 112 is installed at least in the upper zone for heating.
Instead of the arrangement according to
