Definitions
- This invention is related to automated vehicle parking garages and associated systems.
- Automated parking garage systems typically utilize one of two methods to store and retrieve vehicles.
- a first prior art method employs pallets and assigns a separate pallet to each vehicle storage bay.
- the pallet associated with the storage bay is transported from the storage bay to the garage entrance where the vehicle is located.
- the vehicle is loaded onto the pallet and the pallet carrying the vehicle is transported to the storage bay where both the pallet and vehicle are stored until retrieved.
- the first prior art method accomplishes the function of transporting vehicles to and from assigned storage bays, it has significant shortcomings.
- a first shortcoming is the inefficient use of time when storing or retrieving a vehicle.
- a driver parking a vehicle is required to idly wait while a pallet is delivered to the garage entrance from an assigned storage bay.
- garages may provide a limited pallet buffer (e.g., five pallets), it is not enough to handle the queues that may occur during periods of high volume business, such as in the morning and afternoon.
- a second shortcoming is that the first prior art method of handling empty pallets impedes the throughput of the garage and fails to provide an endless, continuing and timely stream of pallets.
- a further shortcoming of the first prior art automated parking method is that handling empty pallets impedes the primary purpose of an automated parking garage, that is, the storing and retrieving of vehicles. Specifically, the same equipment that is used to store and retrieve vehicles is utilized to handle empty pallets thereby promoting inefficient utilization of that equipment.
- a single carrier module is used to service all storage bays without the use of pallets.
- the module is stored at an idle position in an aisle of the garage when it is not in use.
- the vehicle is loaded from an entry/exit station onto the module.
- the module carrying the vehicle is transported to the storage bay where the vehicle is unloaded.
- the empty module is transported back to the idle position while the vehicle remains stored until it is retrieved.
- the vehicle is loaded/unloaded to/from the module using either the vehicle's own drive system or a crane that traverses the aisles and reaches from the foundation to the roof.
- the module When a stored vehicle is to be retrieved, the module is transported from the garage entrance to the storage bay in which the vehicle is stored. The vehicle is loaded onto the module and the module carrying the vehicle is transported to the garage exit. The vehicle is then unloaded from the module, and the empty module is transported to the garage idle position where it remains until it is needed to store or retrieve a vehicle.
- the second prior art method eliminates the need to handle empty pallets, it has several shortcomings. Specifically, it requires excessive handling of the vehicle such as grabbing the tires in one way or another. The second prior art method also makes inefficient use of time when storing and retrieving a vehicle. Further, using the second prior art method puts vehicles at risk for being soiled during transportation (such as by oil or hydraulic fluid from the crane).
- an automated parking garage system that addresses the shortcomings of the prior art. Specifically, there is a need for a system that delivers a pallet to an incoming vehicle driver before or shortly after the driver's vehicle enters an automated parking garage. Further, there is a need for a system that reduces the time required to retrieve a stored vehicle. There is still a further need for a system handling empty pallets that does not utilize or otherwise impede the equipment used to store and retrieve vehicles. There is yet a further need for a garage system that provides throughput sufficient to service garage customers during periods of high volume business.
- the present invention disclosed and claimed herein in one aspect thereof, comprises an automated parking garage.
- the garage comprises a multi-floor building having a plurality of vehicle storage racks in a storage area for storing a loaded pallet or an unloaded pallet.
- An entrance-level floor of the building includes an entry/exit station (EES) on for receiving a vehicle, the EES having an exterior entrance through which the vehicle is driven and, an opposing interior entrance that provides access to the storage area and through which the loaded pallet is transported, the loaded pallet and unloaded pallet adapted to be positioned at floor level in the EES.
- the garage includes a pallet stacking station for storing the unloaded pallet, the pallet stacking station located over a shuttle aisle that extends under the EES.
- a pallet shuttle that traverses the shuttle aisle to a first position under the EES for handling the unloaded pallet in the EES, and to a second position under the pallet stacking station for stacking the unloaded pallet.
- the garage also includes a transport system for transporting the loaded pallet in the storage area.
- the garage also includes a mechanism for delivering and storing pallets.
- a pallet shuttle is positioned in a first position under an entry/exit station.
- the entry/exit station is an area for receiving and discharging a vehicle. It includes a pallet and a first retractable pallet support mechanism supporting the pallet.
- the method also includes the step of elevating a support platform of the pallet shuttle to support the pallet.
- the method further includes the steps of retracting the first retractable pallet support mechanism, lowering the support platform and pallet, and moving the pallet shuttle from the first position to a second position under a pallet stacking station for storing a pallet.
- the support platform is then elevated thereby lifting the pallet into the pallet stacking station.
- a second retractable pallet support mechanism operative to support the pallet is then engaged, and the support platform is lowered, thereby causing the second retractable support mechanism to support the lowest pallet in the pallet stacking station.
- Still another aspect of the present invention is directed toward delivery of a pallet to an entry/exit station of the automated parking garage, the pallet shuttle is positioned in a second position under the pallet stacking station.
- the pallet stacking station includes a pallet stack having a lowermost pallet.
- the pallet stacking station also includes a second retractable pallet support mechanism supporting the lowest pallet of the pallet stack.
- the support platform of the pallet shuttle is then elevated, thereby lifting the pallet stack within the pallet stacking station, retracting the second retractable pallet support mechanism, and lowering the support platform, thereby causing the lowermost pallet of the pallet stack to pass through the second retractable support mechanism of the pallet stacking station.
- the second retractable support mechanism is then engaged, thereby supporting all of the pallets of the pallet stack except the lowermost pallet.
- the pallet shuttle and the lowermost pallet are then moved from the second position to the first position under the entry/exit station for receiving and discharging a vehicle.
- the entry/exit station includes the first retractable pallet support mechanism operative to support a pallet.
- the support platform and the pallet are then elevated, thereby positioning the pallet in the entry/exit station, and the first pallet support mechanism is engaged, thereby supporting the pallet.

- the PSS 400 includes a pallet stack support mechanism 410 with pallet latches 411 that provide support for a stack of pallets 412 that are suspended over the pallet shuttle 250 .
- the PSS 400 is used to store the pallets 212 that may be immediately delivered to EES 200 .
- the PSS 400 further serves to store the empty pallets 212 recently removed from the EES 200 .
- the pallet shuttle base 252 of the pallet shuttle 250 traverses on a shuttle rail system carrying the empty pallet 212 and moves into an alignment position under the PSS 400 .
- the PSS 400 and the pallet stack 412 are then lowered to a position where the empty pallet 212 , as supported by the pallet shuttle support platform 256 , is lifted by the pallet shuttle elevation mechanism 254 into the PSS 400 from below, and ultimately placed at the bottom of pallet stack 412 .
- the pallet stack support mechanism 410 is configured to permit the pallet 212 to enter the PSS 400 from underneath, and to provide support for the pallet 212 and the remaining pallets in pallet stack 412 once all of the pallets are rested on pallet support mechanism 410 .
- FIG. 5 there is illustrated the insertion of the pallet 212 into the PSS 400 .
- the pallet shuttle 250 is illustrated with the pallet shuttle support platform 256 elevated such that the pallet 212 is lifted under the pallet stack 412 until the pallet stack support mechanism 410 with the pallet latches 411 catch the pallet 212 from underneath and provide vertical support for pallet stack 412 , once the pallet shuttle support platform 256 is lowered.
- the PSS 400 is designed to accommodate a pallet stack 412 of up to ten pallets. As necessary, the pallet stack 412 may be removed from PSS 400 by a pallet vertical lift (PVL) to an upper/lower floor for medium or long-term storage.
- PVL pallet vertical lift

- FIG. 7 there is illustrated the PSS 400 of FIG. 4, and the PVL 610 partially descended with the tongs 612 in an open stance during the removal process of a pallet stack 412 .
- the PVL 610 operates to lower the tongs 612 along the sides of pallets 212 of the pallet stack 412 , and after the tongs 612 pass the bottom pallet of the pallet stack 412 , the PVL 610 closes the tongs 612 and then lifts the pallet bundle 412 .
- the pallet stacker ten disengages, to an upper/lower floor for medium or long term storage.
- the PVL 610 When bringing a pallet bundle 412 to the PSS 400 , the PVL 610 is fed a pallet bundle 412 from equipment of the upper or lower floor. The PVL 610 then lowers the pallet bundle 412 into the pallet stack support mechanism 410 , where the pallet latches 411 engage the lowest pallet of the pallet bundle 412 . The PVL 610 then further lowers a short distance (e.g., 1-2 inches), and disengages the tongs 612 to an open stance. Once the PVL 610 elevates above the pallet bundle 412 , the PVL 610 then closes the tongs 612 and rises to a upper floor position. The steps are reversed, as indicated in the description hereinbelow, when removing a bundle from the PSS 400 to a storage location.
- a short distance e.g., 1-2 inches
- FIG. 8 there is illustrated a view of the PVL 610 fully descended with the tongs 612 in an open stance.

Description
- This application is a Continuation-in-Part of the following pending U.S. patent applications: Ser. No. 09/364,934 entitled “METHOD AND APPARATUS FOR DISTRIBUTING AND STORING PALLETS IN AN AUTOMATED PARKING STRUCTURE” filed Jul. 30, 1999; and Ser. No. 09/790,460 entitled “METHOD AND APPARATUS FOR DISTRIBUTING AND STORING PALLETS IN AN AUTOMATED PARKING STRUCTURE” filed Feb. 22, 2001, which is a Divisional of the abovementioned Ser. No. 09/364,934, the contents of both that are herein incorporated by reference.
- This invention is related to automated vehicle parking garages and associated systems.
- Automated parking garage systems have been employed since the late 1950's utilizing crane systems, conveyors, hydraulics and pneumatics to transport and store vehicles within a parking structure. Recently, more advanced garage systems have been developed which include computer-controlled, specialized equipment for carrying vehicles to assigned parking spaces in a way similar to the way that computerized assembly lines or warehouses store and retrieve miscellaneous goods. In such assembly line and warehouse systems, a computer assigns a location for each item as it is received from its manufacturer, and robotic equipment carries each item to its assigned location. The same equipment is dispatched to the location when the item requires retrieval. Often, the items stored in a warehouse are placed on pallets to facilitate transportation and storage of the items. The use of pallets as supporting elements for the transport and storing of vehicles is also typical of more advanced automated parking garage systems.
- Examples of automated parking garage systems are described in U.S. Pat. No. 5,467,561 of Takaoka, U.S. Pat. No. 5,556,246 of Broshi, U.S. Pat. No. 5,573,364 of Schneider et al., and U.S. Pat. No. 5,669,753 of Schween.
- Automated parking garage systems typically utilize one of two methods to store and retrieve vehicles. A first prior art method employs pallets and assigns a separate pallet to each vehicle storage bay. In such systems, when a vehicle is to be parked or stored in a storage bay, the pallet associated with the storage bay is transported from the storage bay to the garage entrance where the vehicle is located. The vehicle is loaded onto the pallet and the pallet carrying the vehicle is transported to the storage bay where both the pallet and vehicle are stored until retrieved.
- When a stored vehicle is to be retrieved, the pallet carrying the vehicle is transported from the storage bay to a garage exit. The vehicle is then unloaded from the pallet, and the pallet is transported back to the storage bay until it is needed again to store a vehicle.
- Although the first prior art method accomplishes the function of transporting vehicles to and from assigned storage bays, it has significant shortcomings. A first shortcoming is the inefficient use of time when storing or retrieving a vehicle. Using the first prior art method, a driver parking a vehicle is required to idly wait while a pallet is delivered to the garage entrance from an assigned storage bay. Although garages may provide a limited pallet buffer (e.g., five pallets), it is not enough to handle the queues that may occur during periods of high volume business, such as in the morning and afternoon.
- A second shortcoming is that the first prior art method of handling empty pallets impedes the throughput of the garage and fails to provide an endless, continuing and timely stream of pallets.
- A further shortcoming of the first prior art automated parking method is that handling empty pallets impedes the primary purpose of an automated parking garage, that is, the storing and retrieving of vehicles. Specifically, the same equipment that is used to store and retrieve vehicles is utilized to handle empty pallets thereby promoting inefficient utilization of that equipment.
- Yet another significant shortcoming of the first method is that it can only handle one vehicle and one procedure at a time. Thus, systems employing the first prior art method cannot park an incoming vehicle at the same time they are retrieving an empty pallet, and vice versa. As a result, an unacceptably long queue often forms at the entrance of such a garage during periods of high volume business.
- According to the second prior art method, a single carrier module is used to service all storage bays without the use of pallets. In such systems, the module is stored at an idle position in an aisle of the garage when it is not in use. When a vehicle is to be parked or stored in a storage bay, the vehicle is loaded from an entry/exit station onto the module. The module carrying the vehicle is transported to the storage bay where the vehicle is unloaded. The empty module is transported back to the idle position while the vehicle remains stored until it is retrieved. Typically, the vehicle is loaded/unloaded to/from the module using either the vehicle's own drive system or a crane that traverses the aisles and reaches from the foundation to the roof.
- When a stored vehicle is to be retrieved, the module is transported from the garage entrance to the storage bay in which the vehicle is stored. The vehicle is loaded onto the module and the module carrying the vehicle is transported to the garage exit. The vehicle is then unloaded from the module, and the empty module is transported to the garage idle position where it remains until it is needed to store or retrieve a vehicle.
- Although the second prior art method eliminates the need to handle empty pallets, it has several shortcomings. Specifically, it requires excessive handling of the vehicle such as grabbing the tires in one way or another. The second prior art method also makes inefficient use of time when storing and retrieving a vehicle. Further, using the second prior art method puts vehicles at risk for being soiled during transportation (such as by oil or hydraulic fluid from the crane).
- Accordingly, there is a need for an automated parking garage system that addresses the shortcomings of the prior art. Specifically, there is a need for a system that delivers a pallet to an incoming vehicle driver before or shortly after the driver's vehicle enters an automated parking garage. Further, there is a need for a system that reduces the time required to retrieve a stored vehicle. There is still a further need for a system handling empty pallets that does not utilize or otherwise impede the equipment used to store and retrieve vehicles. There is yet a further need for a garage system that provides throughput sufficient to service garage customers during periods of high volume business.
- The present invention disclosed and claimed herein, in one aspect thereof, comprises an automated parking garage. The garage comprises a multi-floor building having a plurality of vehicle storage racks in a storage area for storing a loaded pallet or an unloaded pallet. An entrance-level floor of the building includes an entry/exit station (EES) on for receiving a vehicle, the EES having an exterior entrance through which the vehicle is driven and, an opposing interior entrance that provides access to the storage area and through which the loaded pallet is transported, the loaded pallet and unloaded pallet adapted to be positioned at floor level in the EES. The garage includes a pallet stacking station for storing the unloaded pallet, the pallet stacking station located over a shuttle aisle that extends under the EES. A pallet shuttle that traverses the shuttle aisle to a first position under the EES for handling the unloaded pallet in the EES, and to a second position under the pallet stacking station for stacking the unloaded pallet. The garage also includes a transport system for transporting the loaded pallet in the storage area.
- The garage also includes a mechanism for delivering and storing pallets. According to another aspect of the present invention directed toward storage of pallets, a pallet shuttle is positioned in a first position under an entry/exit station. The entry/exit station is an area for receiving and discharging a vehicle. It includes a pallet and a first retractable pallet support mechanism supporting the pallet. The method also includes the step of elevating a support platform of the pallet shuttle to support the pallet. The method further includes the steps of retracting the first retractable pallet support mechanism, lowering the support platform and pallet, and moving the pallet shuttle from the first position to a second position under a pallet stacking station for storing a pallet. The support platform is then elevated thereby lifting the pallet into the pallet stacking station. A second retractable pallet support mechanism operative to support the pallet is then engaged, and the support platform is lowered, thereby causing the second retractable support mechanism to support the lowest pallet in the pallet stacking station.
- Still another aspect of the present invention is directed toward delivery of a pallet to an entry/exit station of the automated parking garage, the pallet shuttle is positioned in a second position under the pallet stacking station. The pallet stacking station includes a pallet stack having a lowermost pallet. The pallet stacking station also includes a second retractable pallet support mechanism supporting the lowest pallet of the pallet stack. The support platform of the pallet shuttle is then elevated, thereby lifting the pallet stack within the pallet stacking station, retracting the second retractable pallet support mechanism, and lowering the support platform, thereby causing the lowermost pallet of the pallet stack to pass through the second retractable support mechanism of the pallet stacking station. The second retractable support mechanism is then engaged, thereby supporting all of the pallets of the pallet stack except the lowermost pallet. The pallet shuttle and the lowermost pallet are then moved from the second position to the first position under the entry/exit station for receiving and discharging a vehicle. The entry/exit station includes the first retractable pallet support mechanism operative to support a pallet. The support platform and the pallet are then elevated, thereby positioning the pallet in the entry/exit station, and the first pallet support mechanism is engaged, thereby supporting the pallet.
- It is a further aspect of the present invention to increase the efficiency of an automated parking garage by significantly increasing the throughput of an automated parking garage, and improving the performance of the automated parking garage by, for the most part, handling empty pallets separately from the mechanics employed to store and retrieve vehicles on the all floors of the garage.

- Referring now to the drawings, FIG. 1 illustrates an automated
parking garage 100 that incorporates the method and apparatus for distributing and storing pallets according to the present invention. As shown, automatedparking garage 100 includes six entry/exit stations (EES) 200. EachEES 200 is for receiving and releasing vehicles stored in the automatedparking garage 100. In this particular embodiment, there are provided three pallet stacking stations (PSS) 400 that are located near theseveral EES 200. Of course, more orfewer EES 200 andPSS 400 may be employed depending on the actual and projected throughput of thegarage 100. The one ormore PSS 400 are for storingempty pallets 212, which pallets are used for supporting vehicles during vehicle storage and retrieval operations. Thepallet 212 is removed from thePSS 400 and distributed to theEES 200 as necessary to accommodate incoming vehicles. Thepallet 212 is removed from theEES 200 and stored in thePSS 400 as necessary to accommodate outgoing vehicles.Pallets 212 are transported between the plurality ofEES 200 andPSS 400 using one or more pallet shuttles (not shown, but described more fully hereinbelow). - The automated
parking garage 100 includes a number levels (or floors) each including a plurality ofvehicle storage slots 114 for storing vehicles. As shown, eachstorage slot 114 comprises aninterior storage rack 116 and anexterior storage rack 118 such that thestorage slot 114 may store up to two vehicles. Thus a first vehicle may be stored in theinterior storage rack 116 and a second vehicle may be stored in theexterior storage rack 118. In addition to the storage available for vehicles shown in FIG. 1, storage for vehicles is provided on upper and/or lower floors of the automatedparking garage 100. One or more vertical lift conveyors (VLC) 120 are provided for transporting vehicles between floors of the automatedparking garage 100. Note that the disclosed automated parking garage architecture is sufficiently flexible to accommodate varying rows of parking, for example, two rows, three rows, fours rows, etc. - During storage and retrieval operations, a vehicle is transported on a supporting
pallet 212 between thestorage slot 114 and one of theEES 200 using acarrier module 110. Thecarrier module 110 accomplishes such transportation via anaisle 112. Thecarrier module 110 includes a rack entry module (REM) (described in more detail hereinbelow) for transferring the pallet 212 (in an empty or unloaded state, or carrying a vehicle in a loaded state) between thecarrier module 110 and, the interior and exterior storage racks (116 and 118), anEES 200, or aVLC 120. - The facilities of the automated
parking garage 100, including theVLC 120, thecarrier module 110, REM,pallet shuttle 250, and pallet vertical lift (PVL) 610 (shown in greater detail hereinbelow) are controlled by a central garage computer control system. The central computer control system, executing the appropriate system control software, is preferably housed in one ormore control rooms 126. Theautomated parking garage 100 further includes one ormore lobbies 124 where a customer may request a vehicle to be retrieved, and pay for the automated parking service. - When a vehicle enters the automated
parking garage 100, the vehicle enters one of theEES 200 through an openexterior door 210 and moves onto thepallet 212, both of which are described in greater detail hereinbelow. Before the vehicle enters one of theEES 200, aninterior door 211 is closed to prevent the vehicle occupants from accessing the interior of the automatedparking garage 100. The driver and passengers of the vehicle exit the vehicle andEES 200, and activate the automated parking process via an automated parking teller located just outside of theexterior door 210 of theEES 200, thereby closing theexterior door 210 of theEES 200. In response thereto, thecarrier module 110 moves along theaisle 112 to a position corresponding to theEES 200 through which the vehicle entered thegarage 100. The REM of thecarrier module 110 is controlled to remove the loadedpallet 212 from theEES 200 and retrieve it onto thecarrier module 110. Thecarrier module 110 includes a turntable mechanism (described in greater detail hereinbelow) that then turns 180 degrees so that the vehicle be retrieved to theEES 200 wherein the customer can drive out of theEES 200, stead of having to back out. In an alternative garage embodiment, where one ormore EES 200 are constructed on either side of theaisle 112, the turntable feature may not be necessary since the vehicles can now enter anEES 200 on one side of theaisle 112, and exit via an different EES on the other side. The central computer determines the availability of a select one of the plurality empty storage racks (116 or 118) in which to store the vehicle with supportingpallet 212. The central computer then directs thecarrier module 110 to traverse theaisle 112 to a position corresponding to the predetermined empty storage rack (116 or 118) of thestorage slot 114. - In the event that the predetermined storage rack (116 or 118) is located on a different floor of the
garage 100, thecarrier module 110 is positioned across from one of theVLC 120, and the REM is controlled to transfer thepallet 212 with vehicle to theVLC 120. TheVLC 120 transports thepallet 212 with vehicle to the appropriate floor of the automatedparking garage 100 where both thepallet 212 and vehicle are transferred to anothercarrier module 110 on that floor. Once theother carrier module 110 carrying thepallet 212 with vehicle is in a position corresponding to the predetermined storage rack, e.g.,exterior storage rack 118 on the floor, the REM is controlled to transfer thepallet 212 with vehicle to thepredetermined storage rack 118 for storage. One of ordinary skill in the art will understand that similar steps may be executed when retrieving the vehicle from thestorage rack 118 on either the upper/lower or entrance floors. - According to the present invention, the
pallets 212 that are not in use (i.e., supporting a stored vehicle) are stored in thePSS 400 by a pallet storage and distribution system. In other words, thepallets 212 are distributed from thePSS 400 to anearby EES 200 only as necessary to accommodate incoming vehicles. Similarly, when an outgoing vehicle vacates itspallet 212, the unloadedpallet 212 may be transferred to thePSS 400 for storage. Thepallets 212 stored inPSS 400 provide an immediate inventory of empty pallets for operating theautomated parking garage 100.Additional pallets 212 may be stacked (or accumulated) into pallet bundles in a pallet stack support mechanism (described in greater detail hereinbelow) and stored for future use in an otherwise empty parking rack (e.g., interior rack 116) on upper/lower floors. Suchadditional pallets 212 may be stored and retrieved using either dedicated hardware, or the same hardware used for storing and retrieving vehicles on the upper/lower floors. If dedicated hardware is not used, requests for storing and retrieving pallet stacks to/from storage racks are preferably processed during a lull in the operation of the automated parking garage 100 (such as at 3:00 am) in order to efficiently utilize the resources of the automatedparking garage 100. - Note that there is a number of
VLCs 120 constructed into the garage 100 (six in this embodiment) to provide vertical access between the floors, and that theVLCs 120 are constructed on aninterior row 128. Thus there are corresponding VLC storage racks 130 “behind” theVLCs 120 in anexterior row 132 that can be utilized for storing a vehicle. In order to do so, theVCL 120 must be elevated to the level of theVLC storage rack 130 so that thecarrier module 110 supporting a loadedpallet 212 can insert the loaded pallet across (or through) theVLC 120 to theVLC storage rack 130. Of course, for retrieving the vehicle, theVCL 120 must be in position at the level of theVLC storage rack 130 from which the vehicle is to be retrieved in order for thecarrier module 110 to gain access to the loadedpallet 212 stored in theVLC storage rack 130. - Since the
garage 100 is a multi-level building having a plurality of vehicle storage racks, each level has anaisle 112 with associated rail system and one ormore carrier modules 110 for traversing the length of thegarage 100 at that level. Thecarrier modules 110 of any particular floor operate independently in accordance with instructions from the garage control system. There is also overlapping range of thecarrier modules 110 of any given floor as they traverse the aisle of that floor such that at least twocarrier modules 110 can access thesame storage slot 114 and thesame VLC 120. Of course, thecarrier modules 110 of the entrance level also have overlapping range such that anyEES 200 can be accessed by at least two of thecarrier modules 110 of the entrance level. - Referring now to FIG. 2, there is illustrated an isometric representation of one of the
ESS 200. TheEES 200 is a bay located on an entrance floor of the automatedparking garage 100 at grade level or other levels where vehicles enter or exit thegarage 100, and having dimensions similar to a residential single-car garage. Typically, theEES 200 will have a width of between approximately fourteen and sixteen feet, and a length of between approximately twenty and twenty-two feet. - As indicated above, the
EES 200 includes the interior door 211 (not shown) for providing access between theEES 200 and the interior of the automatedparking garage 100. TheEES 200 further includes theexterior door 210 through which an incoming vehicle may enter or an outgoing vehicle may exit, the automatedparking garage 100. When entering thegarage 100, the incoming vehicle is positioned on thepallet 212, which pallet 212 forms a central portion of the floor ofEES 200. The incoming vehicle may be positioned on thepallet 212 using any number of mechanisms, such as grooves, bumpers, lights (e.g., marquees) and acoustic signals. Apassenger walkway 214 is provided on either side of thepallet 212 to enable the driver and other passengers of a vehicle to exit the vehicle andEES 200 of the automatedparking garage 100 prior to initiation of the vehicle storage process. - The
pallet 212 is supported by two retractable pallet supports 216. Eachretractable pallet support 216 includes atrack 220 and atrack retractor 218. Thepallet 212 has apallet lip 213 running the length of each side. A portion of thepallet lip 213 for each side of thepallet 212 lies on top of therespective track 220. Thepallet 212 is installed into and removed from theEES 200 using apallet shuttle 250. Thepallet shuttle 250 is disposed underneath theEES 200 in a separate runway extending parallel to theaisle 112. Thepallet shuttle 250 includes apallet shuttle base 252 having motive means for moving thepallet shuttle 250 between a first position underneath theEES 200, and a second position underneath the PSS 400 (not shown). The motive means for moving thepallet shuttle 250 may include wheels, a track, and/or any other well-known movement mechanisms. Thepallet shuttle 250 further includes a palletshuttle support platform 256 for carrying theempty pallet 212, and a palletshuttle elevation mechanism 254 for raising and lowering the pallet shuttle support platform 256 (and anypallet 212 supported thereupon). - When the
pallet 212 is distributed to one of theEES 200, thepallet shuttle 250 carrying thepallet 212 is positioned under theappropriate EES 200. The retractablepallet support mechanism 216 is then controlled to cause thetrack retractors 218 to drive thetracks 220 to a retracted position, thereby allowing thepallet shuttle 250 to elevate thepallet 212 into the proper position for installation into theEES 200. To complete the installation of thepallet 212 into theEES 200, each retractablepallet support mechanism 216 causes thecorresponding track retractors 218 to extend, driving thetracks 220 into a support position. Once thetracks 220 are in a support position, the palletshuttle support platform 256 is lowered, causing thepallet 212 to rest onto thetracks 220, and installation of thepallet 212 is complete, leaving thepallet shuttle 250 free to be used for other tasks. One of ordinary skill in the art will recognize that similar steps may be executed to remove thepallet 212 from theEES 200 for storing in thePSS 400. - Reference is now to FIGS. 3A-9 that illustrate the structure and operation of the present invention, including the steps performed for storing the
pallet 212 that has been vacated by an outgoing vehicle. Of course, the same structural elements can be used to perform steps for distributing thepallet 212 to theEES 220 for an incoming vehicle. - FIG. 3A illustrates an isometric representation of the
EES 200, and the structure of the present invention for executing the first steps required for removal of thepallet 212 from theEES 200. As shown, thepallet shuttle 250 causes the palletshuttle elevation mechanism 254 to raise thepallet shuttle platform 256 into a position supporting thepallet 212. Each retractablepallet support mechanism 216 then causes the corresponding track retractor(s) 218 to position thetracks 220 in a retracted position, which clears thepallet lip 213 on each of the sides of thepallet 212. Thepallet 212 and palletshuttle support platform 256 are then lowered by the palletshuttle elevation mechanism 254 by passing through the aperture defined, in part, by thetracks 220. - FIG. 3B shows the status of the
pallet shuttle 250 just after thepallet 212 has been removed from theEES 200. Thepallet shuttle 250 is illustrated with the palletshuttle elevation mechanism 254 in a partially lowered state. Once the palletshuttle elevation mechanism 254 sufficiently lowers the palletshuttle support platform 256 andpallet 212, thepallet shuttle 250 transports thepallet 212 to another part of theparking garage 100 for storage. - Referring now to FIG. 4, there is illustrated a broader view isometric representation of the
EES 200 showing thePSS 400 adjacent to theEES 200. ThePSS 400 includes a palletstack support mechanism 410 with pallet latches 411 that provide support for a stack ofpallets 412 that are suspended over thepallet shuttle 250. ThePSS 400 is used to store thepallets 212 that may be immediately delivered toEES 200. ThePSS 400 further serves to store theempty pallets 212 recently removed from theEES 200. - Once the
pallet 212 has been removed from theEES 200, as illustrated hereinabove in FIG. 3A and FIG. 3B, thepallet shuttle base 252 of thepallet shuttle 250 traverses on a shuttle rail system carrying theempty pallet 212 and moves into an alignment position under thePSS 400. ThePSS 400 and thepallet stack 412 are then lowered to a position where theempty pallet 212, as supported by the palletshuttle support platform 256, is lifted by the palletshuttle elevation mechanism 254 into thePSS 400 from below, and ultimately placed at the bottom ofpallet stack 412. The palletstack support mechanism 410 is configured to permit thepallet 212 to enter thePSS 400 from underneath, and to provide support for thepallet 212 and the remaining pallets inpallet stack 412 once all of the pallets are rested onpallet support mechanism 410. - Referring now to FIG. 5, there is illustrated the insertion of the
pallet 212 into thePSS 400. Thepallet shuttle 250 is illustrated with the palletshuttle support platform 256 elevated such that thepallet 212 is lifted under thepallet stack 412 until the palletstack support mechanism 410 with the pallet latches 411 catch thepallet 212 from underneath and provide vertical support forpallet stack 412, once the palletshuttle support platform 256 is lowered. ThePSS 400 is designed to accommodate apallet stack 412 of up to ten pallets. As necessary, thepallet stack 412 may be removed fromPSS 400 by a pallet vertical lift (PVL) to an upper/lower floor for medium or long-term storage. - FIGS. 6 through 10 illustrate the structure and steps performed to remove the
pallet stack 412 for medium or long-term storage. Referring now to FIG. 6, there is illustrated a representation of thePSS 400. As shown, thePSS 400 is filled to capacity with thepallet stack 412 having tenpallets 212. As further shown in FIG. 6, aPVL 610 is positioned directly above thePSS 400 for lifting thepallet stack 412. ThePVL 610 includes a pair oftongs 612 for supporting the weight ofpallet stack 412 during lifting. ThePVL 610 further includes aPVL support 614 and PVL motive means 616 for raising and lowering thetongs 612. - Referring now to FIG. 7, there is illustrated the
PSS 400 of FIG. 4, and thePVL 610 partially descended with thetongs 612 in an open stance during the removal process of apallet stack 412. ThePVL 610 operates to lower thetongs 612 along the sides ofpallets 212 of thepallet stack 412, and after thetongs 612 pass the bottom pallet of thepallet stack 412, thePVL 610 closes thetongs 612 and then lifts thepallet bundle 412. The pallet stacker ten disengages, to an upper/lower floor for medium or long term storage. - When bringing a
pallet bundle 412 to thePSS 400, thePVL 610 is fed apallet bundle 412 from equipment of the upper or lower floor. ThePVL 610 then lowers thepallet bundle 412 into the palletstack support mechanism 410, where the pallet latches 411 engage the lowest pallet of thepallet bundle 412. ThePVL 610 then further lowers a short distance (e.g., 1-2 inches), and disengages thetongs 612 to an open stance. Once thePVL 610 elevates above thepallet bundle 412, thePVL 610 then closes thetongs 612 and rises to a upper floor position. The steps are reversed, as indicated in the description hereinbelow, when removing a bundle from thePSS 400 to a storage location. - Referring now to FIG. 8, there is illustrated a view of the
PVL 610 fully descended with thetongs 612 in an open stance. - Referring now to FIG. 9, there is illustrated the
PVL 610 in a fully descended position with thetongs 612 in a closed position. Thetongs 612 are illustrated in a closed position in preparation for thePVL 610 rising, and thereby supporting the weight ofpallet stack 412. Thepallet stack 412 is then lifted vertically and removed fromPSS 400 for longer-term storage in another portion ofautomated parking garage 100. Once thePVL 610 is in an upper or lower floor position, secondary parking machinery may be used to retract thepallet stack 412 from thePVL 610. Such secondary parking machinery may then store thepallet stack 412 in an empty vehicle storage rack (e.g. storage rack 116). Of course, a similar process may be employed to retrieve the storedpallet stack 412 and supply it to thePVL 610. - The
PVL 610 lifts thepallet bundle 412 either up or down depending if utilized in an underground garage or an above ground garage; in either case thePVL 610 moves thepallet bundle 412 to a floor other than the entrance floor (i.e., floor with the EES 220). - Referring now to FIG. 10, there is illustrated the
tongs 612 in a closed stance and thePVL 610 in a fully ascended position while supportingpallet stack 412. - Referring now to FIG. 11a, there is illustrated a general diagram of the
EES 200, and the locations of theexterior door 210 andinterior door 211 thereof. - Referring now to FIG. 11b, there is illustrated a more detailed view of the
EES 200. As indicated hereinabove, theEES 200 facilitates entry and exit of a vehicle of theparking garage 100. TheEES 200 is similar in size to a conventional residential single-car garage. TheEES 200 includes theexterior door 210 that provides access by a vehicle to the exterior of thegarage 100 once retrieved, and entry to thegarage 100 for parking, and the interior door 211 (in a cutaway portion) that provides access to the interior of thegarage 100. The exterior and interior doors (210 and 211) can be roll-up doors such that the “up” position puts either door on a rail in the ceiling area of theEES 200. In normal operation, only one door is open at any point in time. - The
EES 200 has aceiling 1100 that is closed off to preclude exposure to mechanisms that may be constructed overhead. Similarly, theEES 200 includes afirst sidewall 1102 and asecond sidewall 1104, both of which are constructed for safety purposes to prevent exposure to the mechanisms interior to thegarage 100. Thefloor area 1103 of theEES 200 includes thepallet 212 and thewalkways 214 on either side of thepallet 212 so that the customer can exit or enter the vehicle from thewalkways 214. The top of thepallet 212 is positioned substantially at floor level with thewalkways 214 to presenting potential trip hazards to customers. As illustrated, thepallet 212 includes a pair of tire guides 1108 into which the vehicle tires should enter when the vehicle is driven onto thepallet 212. This helps the customer determine where to park the vehicle on thepallet 212. - In this particular embodiment, an
automated parking teller 1106 is provided exterior to theEES 200 that the customer accesses to purchase the parking service, and to initiate the parking process. Once the transaction is completed, the customer makes a selection that initiates the parking process, causing theexterior door 210 to close. Note that in an alternative embodiment, the automatedparking teller 1106 can be located inside of theEES 200 such that once the parking transaction is completed at theteller 1106, the customer (and any passengers) must exit theEES 200 prior to the parking process initiating. In either case, the interior of theEES 200 can include one or more motion sensors that prevent initiation of the automated parking garage mechanisms by the garage control system when motion is detected by the presence of the customer and/or passengers in the interior of theEES 200. Thus when the customer has paid for the parking service, and the customer and all passengers have vacated theEES 200, the motion sensors indicate as such, and the control system of thegarage 100 then enables the parking procedure for that vehicle. - At the
EES 200, the transaction includes either giving a ticket, reading an RF (radio frequency) tag (e.g., an EZ pass or similar), or reading a credit card. It is appreciated that other conventional transaction methods can also be provided with suitable accommodations for processing such transactions. Once the customer returns and wants his car back, he/she simply goes to thelobby 124 where a ticket reader, credit card reader, or RF reader is utilized to process the corresponding method for clearing payment, thereby initiating retrieval of the vehicle. A message center in thelobby 124 will tell the customer where to pick up the vehicle (i.e., which of theEES 200 or terminals). - As indicated hereinabove, more robust implementations of the automated
parking teller 1106 can accommodate payment methods that include cash, debit cards, rechargeable pre-purchased parking debit cards, or many other conventional means for completing the transaction. Additionally, theautomated teller 1106, and other automated tellers associated with theother EES 200 of thegarage 100 are networked to one or more computer systems that facilitate the use of the aforementioned payment methods. For example, where a credit card is utilized, theteller 1106 must interface to a network that provides access to the credit database of the card user so that payment can be properly authorized. Such access can be provided via a packet-switched network such as the Internet, by the circuit-switched network of the Public Switched Telephone Network, or GPS (global positioning system). - Additionally, the
garage 100 can be suitably constructed to provide services other than simply parking the car. For example, the customer could, at the time of accessing theautomated teller 1106, select that his or her vehicle be washed during the time in which the vehicle is parked at thegarage 100. Thus at some time, a garage attendant would be made aware of the purchased service, retrieve the vehicle, wash it, and return the vehicle to its parking rack in thegarage 100. Other services can also be provided as desired by the garage owner, in a more robust implementation of thegarage 100 such as performing routine engine maintenance to include changing oil, performing a tune-up, car detailing, etc. - Note that the disclosed
automated garage 100 can be implemented to accommodate storage for items other than vehicles. For example, thepallet 212 can be adapted to accommodate compatible storage containers such that the containers can be delivered, stored, and retrieved utilizing the existing garage equipment and systems. Additionally, such storage containers can be constructed for use within thegarage 100 without using thepallet 212. - Referring now to FIG. 12, there is illustrated a more detailed isometric of the
PSS assembly 400 that includes the palletstack support mechanism 410 andPVL 610. In this particular embodiment, thePSS 400 is constructed into a multi-floorsteel beam framework 1201 suitable for supporting and lifting thepallet bundle 412. ThePSS 400 includes the palletstack support mechanism 410 in which pallets are either accumulated from theEES 200 when vehicles are retrieved for a customer, and removed from thepallet bundle 412 for use in theEES 200 in preparation to receive a vehicle. ThePSS 400 is constructed over ashuttle rail system 1200 that accommodates thepallet shuttle 250. ThePVL 610 is suspended from theframework 1201 such that it can be lowered to either replace or remove thepallet stack 412 of the palletstack support mechanism 410. Thus thePVL 610 operates over the height of several floors, in accordance with the particular garage design, such that when thepallet stack 412 is to be handled, thepallet stack 412 can be elevated to and from upper (or lower floors). - The
PSS 400 includes the PVL motor 616 (e.g., an electro-mechanical motor) that operates in accordance with control signals from the central control system to either raise or lower thePVL 610 by driving arotating shaft 1204 to take in or let out the PVL support 614 (i.e., a suspension means). - In operation, the
pallet shuttle 250, when receiving control signals from the control system computer, traverses theshuttle rail system 1200 in a lateral (or x-axis)direction 1203 from theEES 200, and is positioned under any of thePSS 400 of thegarage 100. Thepallet shuttle 250 includes two pairs ofsteel shuttle wheels 1207 at each end that engage theshuttle rail system 1200. When bringing thepallet 212 to thePSS 400, the control system signals the pallet shuttle elevation mechanism 254 (not shown) contained in thepallet shuttle base 252 of thepallet shuttle 250 to lift the palletshuttle support platform 256. The palletshuttle support platform 256 is raised to a point such that the supportedpallet 212 on the palletshuttle support platform 256 contacts the lowest pallet of thepallet bundle 412, and continues rising forcing thepallet bundle 412 vertically to a height sufficient to allow the palletstack support mechanism 410 to capture thepallet 212 by engaging the support latches 411. The palletshuttle support platform 256 then lowers to a transport position such that thepallet shuttle 250 can traverse theshuttle rail system 1200 in accordance with instructions from the garage control system. - In a scenario where the
pallet bundle 412 is removed from thePSS 400 for storage, thePVL 610 is controlled to lower about thepallet bundle 412. Thetongs 612 are in an open stance for clearing thepallet bundle 412, and thePVL 610 is lowered to a point where thetop edge 1206 of thetongs 612 is just lower than the bottom of the lowest pallet of thepallet bundle 412. Thetongs 612 are then closed and secured for lifting thepallet bundle 412, after the palletstack support mechanism 410 disengages the stack latches 411. ThePVL 610 then rises to a floor predetermined by the garage control system. When brought into position at the designated floor, thePVL 610 is aligned at that floor such that thelower portion 1208 of the channel beam of thetongs 612 facilitates insertion of a REM (not shown) for removal of thepallet bundle 412 from thePVL 610. An upper carrier module (UCM) assembly (described in greater detail hereinbelow) that comprises the REM and UCM accesses thePVL 610 from aUCM rail system 1210 of that floor. - Referring now to FIG. 13, there is illustrated an end view of the
VLC assembly 120. As indicated hereinabove, theVLC assembly 120 operates to transport only loaded in the vertical (or z-axis) direction between the various floors of thegarage 100. TheVLC 120 is constructed within the steel girder structure of thegarage 100 so that acarriage 1300 engages each of four beams at its corners when reaching the appropriate floor (or level). As illustrated, the unloadedcarriage 1300 is positioned in a locking mode at a level of thegarage 100 where one end of thecarriage 1300 is positioned between two end girders (1302 and 1304). Thecarriage 1300 includes an electro-mechanical means 1305 that operates in accordance with control signals from the central control system to rotate alocking shaft 1306 to cause two pairs of opposing locking pins to engage the corner girders. Here, one pair of pins (1308 and 1310) is illustrated as engaged to respective corner girders (1302 and 1304). The electro-mechanical means 1305 connects to another shaft near the other end of thecarriage 1300 to control locking pins at that end in a similar manner. - In this particular rendition, the
VLC 120 is shown with a loaded pallet 212 (i.e., supporting a vehicle 1312). Note that theVLC 120 accommodates the loadedpallet 212 in the same way thepallet 212 is supported by the retractablepallet support mechanism 216 of FIG. 2, that is, by thepallet lips 213. TheREM 1314 associated with the particular floor is shown inserted into thatVLC 120 under the loadedpallet 212 such that thepallet 212 can be raised sufficiently to remove the loadedpallet 212 from the VLC 120 (for a removal operation). TheREM 1314 includes thewheels 1315 for rolling theREM 1314 into theVLC 120 on VLC rails 1316. Thecarriage 1300 also includescorner assemblies 1318 at each corner thereof that connect to vertical lifting means (not shown), for example, chains, so that thecarriage 1300 can be raised or lowered within the vertical shaft of theVLC 120 defined by the corner girders. - Referring now to FIG. 14, there is illustrated a more detailed view of the mechanisms utilized for retrieving and replacing a pallet, loaded or unloaded, in the
EES 200. As illustrated, the unloadedpallet 212 is resting on thetracks 220 within theEES 200. Thetracks 220 can be retracted utilizing a number oftrack retractors 218, which are electro-mechanical devices operating under control of the garage control system. That is, when thepallet 212 is to be retrieved from or returned to the PSS 400 (not shown), thetrack retractors 218 operate to spread the tracks 220 (along the x-axis) sufficiently so that thepallet 212 can be lowered downward (in the z-axis) by thepallet shuttle 250. Similarly, when thepallet 212 is being returned to theEES 200 from thePSS 400, and elevated from below into position such that thepallet lips 213 are just above the supporting surface of thetracks 220, thetrack retractors 218 operate to move thetracks 220 inward so that thepallet 212 can be lowered the short distance thereonto. Note thepallet shuttle 250 travels under theEES 200 on theshuttle rail system 1200, as indicated hereinabove. Note also that thePSS 400 need not be adjacent to theEES 200, since theshuttle rail system 1200 facilitates travel to virtually any location along the length of thegarage 100. - When a customer has departed the
EES 200, and initiated the parking procedure for a vehicle, a type ofcarrier module 110 utilized on the entrance level of thegarage 100, denoted hereinafter as a lower carrier module (LCM)system 1400, is moved into alignment with theEES 200 by the garage control system. TheLCM system 1400 includes anLCM turntable 1402 that rotates 180 degrees in a horizontal plane, alower carrier 1403 havingcarrier wheels 1404 on each end that provide for traversing the length of the garage 100 (on the x-axis) on anLCM rail system 1406, and a lower rack entry module (REM) 1408 for insertion into the EES 200 (in the y-axis). Note that the number and orientation of thelower carrier wheels 1404 are such that at least onewheel 1404 of a pair is always in a supporting role of thelower carrier 1403 on theLCM rail system 1406. - The
LCM turntable 1402 includes a rail (or wheel guide) 1410 on each side into which thewheels 1412 on either side of thelower carrier REM 1408 travel. The lower carrier REM rails 1410 of theLCM turntable 1402 are designed to align with a lower inside L-portion 1414 of the channel beams that function as thetracks 220 that support the loadedpallet 212 in theEES 200. The lower inside L-portion 1414 of eachtrack 220 functions as a rail over which thewheels 1412 roll in order to position thelower carrier REM 1408 under thepallet 212. Note that therails 1410 need not be in close proximity or direct contact with the corresponding lower inside L-portion 1414, since theREM wheels 1412 are grouped into pairs that are suitably spaced in a supporting role. If the loadedpallet 212 is selected for storage on the current floor, theLCM system 1400 moves to the designatedstorage slot 114, and theREM 1408 extends into either theinterior storage rack 116 or fully to theexterior storage rack 118 to store the loadedpallet 212. - Alternatively, if the garage control system directs that the loaded
pallet 212 is to be stored on a different floor, theLCM system 1400 and loadedpallet 212 move to the VLC 120 (not shown) where the loadedpallet 212 is placed into theVLC 120 for vertical movement to the other floor. - The
lower carrier REM 1408 of theLCM system 1400 includes a lower REM control means 1416 that communicates with the garage control system to process signals that control functions of thelower carrier REM 1408, including movement into and out of theEES 200 and elevation of an elevating means. The lower REM control means 1416 connects electrically to a firstwheel drive section 1417, which firstwheel drive section 1417 includes the following general components (that are not illustrated here, but are shown in greater detail in FIG. 17): a first drive means, a first transfer means, and a first set of fourwheels 1412 with a pair located on each side and near the end of the REM chassis. The lower REM control means 1416 also connects electrically to a secondwheel drive section 1419, which secondwheel drive section 1419 includes a second drive means, a second transfer means, and a second set of fourwheels 1413 with a pair located on each side and near the opposite end of the REM chassis. The first and second drive means may be one or more electro-mechanical motors that drive the wheels (1412 and 1413) so that thelower carrier REM 1408 moves along the y-axis into and out of thetracks 220 of theEES 200. The first and second transfer means that transfer the drive torque from the first (and second) drive means to the wheels 1412 (and 1413) can include any combination of conventional equipment such as shafts, gears, belts and pulleys, or chains that suitably designed into thelower carrier REM 1408 to facilitate such functions. - The
lower REM 1408 also includes a lower REM elevator motive means 1418 under control of the lower REM control means 1416 so that an elevator component (not shown) of thelower REM 1408 can be raised to support the loaded or unloadedpallet 212 in theEES 200, and lowered for transport of the pallet and/or vehicle along theLCM rail system 1406. The elevator component comprises a platform for mating with the underside of thepallet 212 to prevent shifting of thepallet 212 during transport. The lower REM elevator motive means 1418 includes one or more electric motors of sufficient operating parameters to drive raising and lowering of thepallet 212 when loaded. The elevator component can include several screw jacks, screw actuators, or similar means that connect to the lower REM elevator motive means 1418 to facilitate the elevating process of thelower carrier REM 1408. - The
lower carrier 1403 also includes a lower carrier control means (not shown) in communication with the garage control system, and a lower carrier drive means (not shown) both of which facilitate operation thereof along theLCM rail system 1406 to position theLCM 1400 in alignment with thetracks 220. Once aligned, thelower carrier REM 1408 moves along thetracks 220 under thepallet 212, and raises thepallet 212 sufficiently to clear thetracks 220, and exits theEES 200 back onto theLCM 1402 with thepallet 212. Of course, thelower carrier REM 1408 is of a width that allows it to be elevated between thetracks 220 when the tracks are closed in a supporting role, to support thepallet 212 for removal from theEES 200. As described, thetrack retractors 218 need not be operated when removing or retrieving a loadedpallet 212 from theEES 200. - Note that
LCM assembly 1400 is only operable on the entrance level floor, while the UCM assembly operates on any floor other than the entrance level floor. Floors other than the entrance level floor have only a fraction of the vehicle-handling load performed on the entrance floor. Thus the UCM assembly is more often available to move thepallet bundle 412 in and out of thePVL 610, and into and out of storage slots on those floors. TheVLC 120 andLCM assembly 1400 preferably are never utilized to handlepallet bundles 412 or an empty pallet; these machines should only handle loaded pallets. The UCM assemblies handle only a portion of the vehicles depending on the number of floors in thegarage 100. - Referring now to FIG. 15, there is illustrated the
carrier module 110 utilized in the levels of thegarage 100 other than the entrance level, and hereinafter denoted specifically as an upper carrier module (UCM)assembly 1500. TheUCM assembly 1500 includes anupper carrier 1502 and an upper carrier REM 1504 (similar to lower carrier REM 1408). Theupper carrier 1502 is similar to thelower carrier 1403 of theLCM system 1400, except that theupper carrier 1502 includes upper carrier rails (or wheel guides, similar to therails 1410 of the LCM system 1400) 1506 within which wheels 1508 (similar to thewheels 1412 of thelower carrier REM 1408 of the LCM system 1400) situated on either side of theupper carrier REM 1504 travel to facilitate movement of theupper carrier REM 1504 along the y-axis. Thus generally, the only difference between theLCM assembly 1400 and theUCM assembly 1500 is that theLCM assembly 1400 includes theLCM turntable 1402 with therails 1410, and theUCM assembly 1500 includes theupper carrier 1502 with therails 1506, but not turntable feature. TheUCM system 1500 includes an upper REM control means 1510 and an upper REM motive means 1512, both of which provide similar functions as the corresponding control means 1416 and motive means 1418 of thelower carrier REM 1408. - The upper REM control means1510 communicates with the garage control system to process signals that control functions of the
upper carrier REM 1504, including movement into and out of the storage slot 114 (extending across theinterior storage rack 116 to the exterior storage rack 118) and elevation of an elevating means. The upper REM control means 1510 connects electrically to a firstwheel drive section 1511, which firstwheel drive section 1511 includes the following general components (that are not illustrated here, but are shown in greater detail in FIG. 17): a first drive means, a first transfer means, and a first set of fourwheels 1508 with a pair located on each side and near the end of the upper carrier REM chassis. The upper REM control means 1510 also connects electrically to a secondwheel drive section 1513, which secondwheel drive section 1513 includes a second drive means, a second transfer means, and a second set of fourwheels 1509 with a pair located on each side and near the opposite end of the upper carrier REM chassis. The first and second drive means may be one or more electro-mechanical motors that drive the wheels (1508 and 1509) so that theupper carrier REM 1504 moves along the y-axis into and out oftracks 1514 of thestorage slot 114. The first and second transfer means that transfer the drive torque from the first (and second) drive means to the wheels 1508 (and 1509) can include any combination of conventional equipment such as shafts, gears, belts and pulleys, or chains that suitably designed into theupper carrier REM 1504 to facilitate such functions. - The
upper carrier REM 1504 also includes an upper REM elevator motive means 1512 under control of the upper REM control means 1510 so that an elevator component (not shown) of theupper carrier REM 1504 can be raised or lowered while supporting the loaded or unloadedpallet 212, and further lowered for transport of thepallet 212 and/or vehicle along aUCM rail system 1516. The elevator component comprises a platform for mating with the underside of thepallet 212 to prevent shifting of thepallet 212 during transport. The upper carrier REM elevator motive means 1512 includes one or more electric motors of sufficient operating parameters to drive the raising and lowering of thepallet 212 when loaded. The elevator component can include several screw jacks that connect to the upper carrier REM elevator motive means 1512 to facilitate the elevating process of theupper carrier REM 1504. Theupper carrier 1502 includes similar arrangements, e.g., a control box, drive sets, etc. to move in the x-axis along the aisles of the associated floors. - In this particular scenario, the unloaded
pallet 212 is stored in one of the manyvehicle storage slots 114 of the upper (or lower) levels of thegarage 100. Thus thestorage slot 114 includes the support beams 1514 that are fixed within the garage structure. Similar to theLCM system 1400 mentioned hereinabove, theUCM system 1500 operates over theUCM rail system 1516 extending essentially the length of thegarage 100. Each level includes a singleUCM rail system 1516 and one ormore UCM systems 1500 operating independently under control of the garage control system to retrieve or store loaded and unloadedpallets 212. - In operation, the
UCM system 1500 moves into alignment with thestorage slot 114 under control of the garage control system. The alignment process is similar to that of theLCM system 1400 such that the upper carrier wheel guides 1506 are aligned with a lower L-portion 1518 of the corresponding support beams 1514. Theupper carrier REM 1504 is then controlled to move onto the lower L-portion of the support beams 1514 in a position under thepallet 212. Thecarrier module 1502 remains in alignment position while theupper carrier REM 1504 elevates to support thepallet 212. Theupper carrier REM 1504 is then controlled to return onto theupper carrier 1502. Similar to operation of thelower carrier REM 1408, upon return, theupper carrier REM 1504 lowers back to a more stable position onto theupper carrier 1502 for transport of thepallet 212 to one of theseveral VLCs 120. - Referring now to FIG. 16, there is illustrated a more detailed mechanical view of the
pallet shuttle 250. As indicated hereinabove, thepallet shuttle 250 comprises thepallet shuttle base 252, the palletshuttle elevation mechanism 254, and palletshuttle support platform 256. Thepallet shuttle base 252 includes theshuttle wheels 1207 on each end that are in rolling contact with theshuttle rail system 1200. The palletshuttle elevation mechanism 254 comprises four mechanical screw actuators (1600, 1602, 1604, and 1606) that operate from an elevation drive means 1607 that is under the coordinated control of a shuttle control means 1608, which shuttle control means 1608 communicates with the garage control system at thecontrol room 126 to facilitate operation of thepallet shuttle 250. The palletshuttle elevation mechanism 254 elevates between thetracks 220 when in theEES 200 to position sufficient to support the unloaded pallet so that thetracks 220 can be retracted (or spread apart) by thetrack retractors 218. When operating with thePSS 400, the palletshuttle elevation mechanism 254 elevates to a position sufficient to support all of thepallets 212 currently stored in thePSS 400, and where stack latches 411 of the palletstack support mechanism 410 can then move to support a portion of the bottom pallet of the stack ofpallets 412. - The
pallet shuttle base 252 includes one or more shuttle drive means 1610 (e.g., electric motors) for driving thewheels 1207 to travel along theshuttle rail system 1200, and to lock into position thepallet shuttle 250 when vertically aligned under theEES 200 or any of thePCC 400 locations to handle thepallet 212. The drive means 1610 couple tocorresponding gear boxes 1612 in which transfer equipment resides to couple the drive means 1610 to the corresponding wheel sets 1207. As indicated hereinabove, such transfer equipment can include belts, pulleys, gears, chains, and shafts as used conventionally with such equipment. - Referring now to FIG. 17, there is illustrated a more detailed mechanical view of a REM1700 (similar to
lower carrier REM 1408 and upper carrier REM 1504). TheREM 1700 includes a first wheel drive section 1702 and a secondwheel drive section 1704. The first wheel drive section 1702 includes a first wheel drive means 1706 (e.g., an electro-mechanical motor) that operates under control of a REM control means 1708 (similar to lower carrier control means 1416 and upper carrier control means 1510). The first wheel drive means 1706 is mounted to a first transfer means 1710 such that torque provided therefrom is transferred to thewheels 1712 associated with the first wheel drive section 1702. As indicated hereinabove, such transfer is suitably provided by conventional mechanisms such as belts and pulleys, gears, chains and/or shafts. - Similarly, the second
wheel drive section 1704 includes a second wheel drive means 1714 (e.g., an electro-mechanical motor) that operates under control of the REM control means 1708. The second wheel drive means 1714 is mounted to a second transfer means 1716 such that torque provided therefrom is transferred to thewheels 1718 associated with the secondwheel drive section 1704. Note that the first and second drive means (1706 and 1714) are operated synchronously by the REM control means 1708. However, it is appreciated that the first and second drive means (1706 and 1714) may also be operated independent of one another, which provides a back-up feature if one of the drive means (1706 or 1714) should fail. - The
REM 1700 also includes an elevator motive means 1720 under control of the REM control means 1708 so that an elevator component (not shown) can be raised or lowered while supporting the loaded or unloadedpallet 212, and further lowered for transport of thepallet 212 and/or vehicle. The elevator component comprises a platform for mating with the underside of thepallet 212 to prevent shifting of thepallet 212 during transport. The REM elevator motive means 1720 includes one or more electric motors of sufficient operating parameters to drive the raising and lowering of thepallet 212 when loaded. The elevator component can include several screw actuators or similar means located in elevator gear boxes (1722 and 1724), and that connect to the REM elevator motive means 1720 to facilitate the elevating process. - Note that all vehicle storage operations in the storage area of the garage100 (i.e., the area of vehicle storage racks) and handling of loaded pallets to and from the EES, can be generalized as being accomplished by a transport system, which transport system includes the
VLC assembly 120, theLCM system 1400,UCM assembly 1500, carrier aisle systems, etc., although the UCM can be used to handlepallet bundles 412, which of course, are unloaded pallets. As mentioned hereinabove, thePSS 400 handles only unloaded pallets. - Since the
garage 100 includes a number of upper and lower module systems (1400 and 1500) operating independently under control of the garage control system on various levels, it is appreciated that communication from the garage control system to the module systems (1400 and 1500) is preferably, but not necessarily, wireless to preclude the need for large wiring harness and extensive routings of cable suspended throughout the garage structure. Thus each module system (1400 and 1500) would communicate wirelessly with the garage control system via a unique frequency. - Although this invention has been described in its preferred forms with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been made only by way of example and numerous changes in the details of construction and combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention.
