Description

The The invention relates to a method and a device for storage and retrieving vehicles on pallets between a transfer station with a pallet changer and parking boxes of an automated parking garage by means of a stacking device.

The Invention is preferably suitable for use in small car parks.

In usual automated parking garages Storage and retrieval of vehicles usually takes place in several over- and side-by-side parking boxes. The parking boxes form shelves, one group each one above the other arranged parking boxes is referred to as a shelf column. rack columns can also as mobile racks, especially as suspended racks, be educated. Usually In the process, vehicles to be stored are first transferred to a transfer station driven on an empty pallet and then including this Picked up pallet from the stacker.

Then the drives Stacking device with the vehicle and pallet an empty parking box and push vehicle with pallet into this parking box.

To the Outsourcing is common the outsourced vehicle with the pallet through the stacker taken from a parking box and with the respective pallet of the transfer station fed.

there is also known to arrange revolving devices that serve outsourced vehicles against the direction of travel into the transfer station bring in the vehicle was retracted during storage.

in the State of the art are various methods and devices for storage and retrieval of Vehicles on pallets between a transfer station and parking boxes an automated parking garage by means of a stacker known.

For example automatic parking systems are known in which neither the transfer station nor the parking boxes are equipped with so-called pallet changers. In these known methods and devices takes over at a storage a stacking a pallet with a parked vehicle from the transfer station and transported the Pallet with the vehicle to be stored to a free parking box, in which the pallet is inserted with the vehicle. Then remove the stacking device an empty palette of one possible close to the just populated Parkbox located another parking box, transported the empty pallet to the transfer station and pushes them into the transfer station, so there the next one Vehicle placed on the new range and then stored can be. The outsourcing of vehicles in these known Systems are done in reverse order.

adversely is the high time required in these known methods and devices during storage and retrieval, because the transfer station with a new Vehicle only then be refitted can when the stacking device has returned from the loading process and placed a new, empty pallet in the transfer station.

Of Further are methods and devices for storage and retrieval of vehicles on pallets between a transfer station and parking boxes an automated parking garage known in which pallet changer in the transfer station be used. It will coincide with the parking of a einulagernden vehicle in the transfer station from the stacker an empty palette of one possible taken from nearby parking box and from the stacking device to the transfer station transported and arranged there in a below the transfer station Pallet changer inserted. Subsequently, by the stacking device the vehicle with the pallet at the top of the pallet changer removed and transported to the parking box, from the previously empty Pallet was removed. Meanwhile becomes the empty pallet previously inserted in the pallet changer below raised and for provided a new parking process for storage of a vehicle. If during the storage process all Parking boxes of a rack column are occupied by vehicles, the Stacking this shelf column for another storage leave and go to another shelf column to find another, to pick up an empty palette. With the newly added empty palette she drives Stacking device the transfer station again. With successive outsourcing of Vehicles will each have an empty pallet from the stacker in a not equipped with a pallet parking box of a particular Shelf slot inserted. Then the stacker moves from this Regal column to that rack column, in which the parking box with the outsourced vehicle is located and attacks in this parking box parked vehicle with its pallet.

adversely are in these methods and devices, the high storage and removal times, the by approaching various shelf columns when storing a Vehicle or when outsourcing a vehicle are required.

Out JP 0 83 38 150 A are procedures and Devices for storing and retrieving vehicles on pallets in an automated parking garage are known in which a plurality of pallets are stored in a pallet storage.

adversely is that such devices because of the required huge Pallet storage technically complex are.

Of Furthermore, methods and devices of the system "Stopa" for storage and retrieval of Vehicles on pallets between a transfer station with a pallet changer and parking boxes of an automated parking garage by means of a stacker known in which each parking box with an additional exchange compartment for a blank Pallet stocked is and wherein the stacking device also with a pallet changer is provided. At the same time during a recording takes place Pallet with a vehicle from the transfer station through the stacker the insertion of an empty pallet from the stacker in the transfer station. For storage of the vehicle with the pallet, the stacking device moves a not occupied with a vehicle parking box and pushes the vehicle with the pallet in this parking box; at the same time the pallet changer removes the stacker an empty pallet from the exchange compartment of this parking box. These methods and devices do not need to be different for any in-and-out operation Shelf columns approached for picking up or storing empty pallets become; This results in relatively short removal times.

Out JP 09041695 A Similar methods and devices for storing and retrieving vehicles on pallets in an automated parking garage are known in which also two pallets are provided for each parking box.

adversely are the complex technical in these methods and devices Execution and the associated with the large number of required exchanges cost-intensive Technology. However, it is particularly disadvantageous that the arrangement a space-consuming exchange compartment under each parking box more valuable Parking space for the plant is lost.

Of the Invention is based on the object, a method and an apparatus for storing and retrieving vehicles on pallets between a transfer station with a pallet changer and parking boxes of an automated parking garage indicate by means of a stacking device, which at high occupation density of the parking garage with vehicles and with little technological effort Short storage and retrieval times of vehicles in and out of parking boxes allow.
