BACKGROUND OF THE INVENTION The present invention relates to article storage and retrieval apparatus, particularly that apparatus having a performance suitable for use in storage and retrieval of information-bearing documents.

Document-containing article storage and retrieval apparatus to be most viable should be connectable to a data processing system. Because such data processing systems operate at electronic speeds, it is most important that the article storage and retrieval apparatus operate as quickly as possible in storing and retrieving articles. Using the techniques described by Burke et al supra, a large number of document-containing articles can be stored and retrieved in a relatively small volumetric space. Because the data base requirements of data processing systems have been constantly growing, the numberof documents to be stored has correspondingly increased. Additionally, to enable successful marketing of such a system, it is highly desirable that such storage and retrieval apparatus be modular; that is, the apparatus should be extensible in order to accommodate different data base requirements in different data processing systems.

When high-speed transport apparatus employed in such storage and retrieval apparatus is required to travel in close tolerance travelways, severe problems arise in making such apparatus extensible; that is, minute offsets between cabinets connected together for making an extensible set of storage walls can cause difficulty in operation, failure, or excessive wear. For example, a pair of facing storage walls 6 feet high are spaced apart less than 12 inches, with a traveling elevator carriage therebetween permitting an out-ofsquareness of less than one-sixteenth of an inch. That is, a greater out-of-squareness may result in the carriage crashing into one of the storage walls. It is seen that to maintain such tolerances over an extremely long distance, such as 100 feet, special precautions have to be taken. The above objectives are to be achieved at minimum cost and yet provide ready attachment of cabinets for facilitating modular extension of storage and retrieval apparatus to afford salutory effects in a data processing operation.

Additionally, document processing stations attached to such apparatus for effecting information data signal exchanges usually require air flow and cooling. The travelways and storage apparatus should be designed to accommodate sealing of the travelway for facilitating control of air flow in the total system.

One of the problems of installing such extensible storage apparatus is that the floors on which such apparatus is mounted may vary from flatness. For example, if the apparatus is installed in the basement, the concrete floor will have undulations. As stated above, any minute undulations can cause severe problems in a high-performance storage and retrieval apparatus to which the present invention is directed.

SUMMARY OF THE INVENTION It is an object of thepresent invention to provide a simple, low-cost, easily assemblable storage and retrieval module which is attachable to other such modules for constructing an elongated and extensible article storage and retrieval apparatus for facilitating precision rapid storage and retrieval operations.

A storage module constructed in accordance with the present invention may include an outer frame having a bottom wall and a pair of upstanding side walls or supports, or a single upstanding side wall. An inner frame consisting of an axially elongated rectangular hollow cylinder has planar rigid bottom, top, and side walls with first and second cylindrical end portions. It is preferred that the inner frame consists of honeycomb sandwich material for maximum rigidity. The two frames are interconnected by first and second pairs of shock mount means at the upper and lower end portions of the side walls. Such shock mount means provide for resiliency in the vertical direction and provide anchors in the horizontal directions. The shock absorbing axes are preferably vertical.

Additionally, equalizing means are interposed between the two bottom walls for facilitating automatic self-adjustments between the two frames for enabling the inner frame to assume a precise horizontal position of its bottom wall irrespective of variations of the outer frame adjustments. Plural interconnecting means are provided at each end of the modules for connection to an adjacent module. The connections provide connecting forces parallel to the elongation of the two cylinders being connected together. Additionally, a tight seal is provided between the abutting ends of the elongated rectangular hollow cylinders. The above arrangement enables a large plurality of modules to be interconnected with all of the inner frames being in a precise colinear relationship.

It is preferred that the travelways between the facing open storage walls supported by the inner frame have lengths equal to the elongation of the rectangular hollow cylinders. Junctions between rails of adjacent cabinets are made in the center of the modules. These connections add rigidity to the entire structure resulting in a truss-like inner frame extending along a plurality of such storage modules. It is also preferred that an upper rail be provided for guiding the traveling elevatorcarriage system of the storage apparatus, which also adds rigidity to the trussed inner frame. Such adjustable yet rigid apparatus enables the above-referred-to colinearity of several interconnected modules.

The storage walls supported by the inner frame are secured to the honeycomb-type side walls at a large plurality of positions for further adding rigidity to the inner frame.

lt is desired that the outer frame be constructed such that document-handling apparatus may be cantilevered from either of the inner frame side walls without disturbing the equilibrium of the trussed support system.

The foregoing and other objects, features, and advantages of the invention will become apparent from the following more particular description of the preferred embodiment as shown in the accompanying drawing.

DETAILED DESCRIPTION Referring now more particularly to the appended drawings, like numerals indicate like parts and structural features in the various diagrammatic views. The article storage and retrieval apparatus consists of a plurality of storage modules 10 connected in a tandem manner as best seen in FIG. 1. After being securely attached to each other, modules 10 form a single continuous colinear storage and retrieval apparatus.

Each module 10 consists of an outer frame 11 shown as consisting of a plurality of welded channels of generally rectangular cubical shape. Each outer frame 11 has at least four depending support pods 12 at the respective corners. These pods are preferably adjustable for accommodating undulations in the floor on which the apparatus is to be installed. Precise leveling of the outer frame during installation of the apparatus is highly desirable. In a given installation, outer frame 11 would be covered with suitable paneling for improving the aesthetic qualities of the apparatus. Inside each outer frame 11 is accurately disposed inner frame 13 consisting of an axially elongated rectangular hollow cylinder with walls formed of rigid honeycomb material of known design. The sandwich honeycomb sheets forming the walls of inner frame 13 are preferably reinforced at the corners by angled reinforcing members 15 which extend the length of the frame at each corner.

To enable a precise'colinear interconnection, each inner frame 13 is supported through shock mounts and equalizer means to the respective outer frames. At the upper ends of the

side walls

16 and 17 are a pair of shock mounts 18 and 19 connecting the inner frame side walls to the outer frame. These shock mounts, of known design, are rigid in the horizontal plane but provide limited flexibility along the vertical axis. Accordingly, shock mounts 18 and 19 provide horizontal stability for the inner frame at the upper end portions while permitting limited vertical adjustments which facilitate module interconnections as will become apparent. Shock mounts 18 and 19 are respectively at both end portions of the modules as best seen in the side elevational views.

The bottom connections between the inner frame 13 and outer frame 11 include equalizing means permitting limited horizontal movement of inner frame 13 with respect to outer frame 11. Details of such equalizing will be described in detail with respect to the various embodiments.

Adjacent modules are firmly secured together at a plurality of points on the periphery of the inner frames. Each inner frame has a set of securing brackets 22-25. A bolt extends through apertures in the respective brackets and a nut is tightened on eachbolt for drawing modules into sealing engagement and for adjusting and locking and inner frames at the correct spacing. A suitable sealing material, such as foam rubber in the form of gasket 26, may be suitably disposed between the abutting ends of two adjacent inner frames as best in FIG. 8. When the bolts in the respective brackets are tightened with the sealing gasket, an air-tight seal is provided between the adjacent inner frames. The number of sealing brackets 22-25 may be varied from that shown in the figures in accordance with known design choices.

A pair of

storage compartment walls

28 and 29 is secured at a plurality of points to

side walls

16 and 17. Preferably,

storage walls

28 and 29 are substantially coextensive with the axial length of

walls

16 and 17. Walls '28 and 29 can be secured to

walls

16 and 17, respectively, by a plurality of bolts, or may be adhesively secured thereto.

The lower ends of the

walls

28 and 29 are several inches above bottom wall 30 of the inner frame. This space is used to accommodate support rail 31 on which carriage 32 is movably disposed. Carriage 32 includes an elevator system consisting of an elevator post 33 and elevator unit 34. Cable support arm 36 extends outwardly from carriage 32 under storage wall 28 to support flexible belt signal and power cable 37 which rides in upwardly opening U-channel 38. Rail 31 is supported at spaced-apart points to side walls 17 by a plurality of brackets 39. The upper end of elevator post 33 is movably supported by depending guide rail 40.

Guide rail 40 and main rail 31 add to the rigidity and precision of connections between adjacent storage modules 10. Each

rail

31 and 40 has a length equal to the axial length of each inner frame 13. The connection between adjacent rails is made midway in each of the inner frames; that is, each of the

rails

31 and 40 extends .between two adjacent modules. As seen in the side views, an elongated bracket 43 securely bolted to the respective abutting end portions of two rails completes the rail support assembly. Each bracket 43 for main rail 31 has a pair of support brackets 39 extending to wall 17. From the above description and inspection of the figures, it should be seen that the pair of rails and their attachment, resectively to side wall 17 and upper wall 44, adds to the rigidity of the inner frames in such a manner that they are effectively a truss connection along the length of the article storage and retrieval apparatus. This adjustable rigidity ensures all connected inner frames 13 are truly colinear.

It is preferred that each inner frame 13 and the mounting of

storage walls

28 and 29 thereon be manufactured in a very precise manner such that positioning control for carriage 32 is greatly simplified. For example, carriae 32 has a light-emitting source and a lightsensing source respectively in sensing portion 46, which operates with position indicating strips 47 suitably supported on storage wall 29. The addressing strips 47, when accurately positioned with respect to storage wall 29, provide positioning information for that wall and also for storage wall 28; hence, only one positioning, sensing, and control system need be provided for both facing storage walls. This reduces cost and simplifies control circuits. When a small document-containing article, such as one that is two inches square, is provided over a distance of 100 feet with a height of over six feet of

storage walls

28 and 29, the described rigidizing structure, together with precision manufacturing, enables the use of but one position sensing system. Such system may be that described by Beach et al, supra.

Equalizing means connect the bottom portions of inner frame 13 with the corresponding bottom portion of outer frame 11. Three different embodiments are shown. Referring firstly to FIGS. 2 and 3, a first embodiment is described. A pair of shock mounts 50 and 51 are disposed at each axial end portion of modules 10. Joining the shock mounts is a flexible cable 52 which extends under inner frame 13 via a pair of sheaves 53 and 54'rigidly secured to bottom wall 30. A pair of facing rubber restraining bumpers 55 at each end portion completes the assembly. Because of the weight in inner frame 13, with

sheaves

53 and 54 on flexible cable 52, it will seek its own horizontal level by minute movements of the inner frame. Therefore, during installation, i.e., during leveling of outer frames 11, inner frame 13 will move from side to side as the outer frame is leveled. Shocks l8 and 19 in the upper end portions accommodate such movement along the vertical axis causing a pivoting motion about a horizontal axis along the length of the elongated inner frame during installation. Accordingly, as the apparatus is installed, bottom wall 30 of inner frame 13 will seek to become parallel, in a perfect horizontal position, with respect to bottom wall '56 of outer frame 11.

FIGS. 4, 5, and 6 illustrate the preferred equalizing apparatus of the present invention. A rigid tubular bar 60 is pivotally secured to bottom wall 56 of outer frame 11. The pivot axis is preferably centrally disposed with respect to bottom wall 30 of inner frame 13. A rigid support plate 61 extends transverse to thelength of each module at the respective end portions as best seen in FIG. 5. Each plate has two depending fastener bolts 62 (FIG. 6) extending through a pair of resilient grommets 63 into apertured bosses 64 at opposite ends of equalizing bar 60. A pair of nuts 65 secures pivot bar 60 to the assembly. During installation, bar 60 is allowed to pivot as outer frame 1 1 is leveled. Inner frame 13 pivots as above described for the first embodiment. It is to be appreciated that the pivoting is quite limited. As best seen in FIG. 4, one pair of the upper shock mounts 19 (such as shown in FIG. 2) is dispensed with, with only one upper shock mount 18 being used at each end portion or in the center. Because of the support provided by the equalizing apparatus 60 et seg, the additional shock mounts could be dispensed with. Also, note that outer frame 1 l is L-shaped, the equalizing apparatus supplying a sufficiently stable support that but one side walled outer frame with one shock mount is elongated plate 43 with two rails 31. The FIG. 9 detail, none of which forms a part of the present invention, shows details of the mount at one end of a rail 31. One bolt secures the respective end of a rail 31 to elongated plate or bracket 43. Support brackets 39 are webs in the L-shaped bracket 43. A pair of shock mounts secures bracket 43 to bottom wall 30.

Referring next to FIG. 7, a third embodiment of the equalizing apparatus is described. A pair of bell cranks are disposed at each comer of inner frame 13 and at both ends. The bell cranks are pivoted outwardly of the

side walls

16 and 17. Tie rod 72 extends between one arm of each of the bell cranks. The other arm of the bell cranks engage shock mounts 73. During installation, shock mounts 73 absorb small changes as outer frame 11 is leveled to the desired accuracy.

While the invention has been particularly shown and described with reference to a preferred embodiment thereof, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention. 1
