DESCRIPTION:
BRIEF SUMMARY
The invention relates to a storing system with a conveying device for conveying heavy objects placed in an entry point to depositing spaces arranged in at least one tier above and adjacent to each other and from the respective depositing space to an exit point, in particular in a multi-storey car park for the automatic parking and unparking of vehicles, with a lift system consisting of at least one tower-like frame which extends over the entire height of the storing system and can be moved along a horizontal guide, a receiving device arranged in the tower-like frame and capable of being moved up and down along a vertical guide, two roller rails, running parallel to each other, arranged on opposite sides in the receiving device and lying perpendicular to the horizontal guide of the tower-like frame, as well as stationary roller rails arranged in the individual depositing spaces and with which the roller rails of the receiving device can be aligned.
In a known storing system which is designed for multi-storey car parks, a hydraulically actuatable lifting platform is provided. A separate transporting wagon is arranged on this platform and can be moved horizontally. The vehicles parked in an entry point are drawn using a transfer device onto the transporting wagon which is then conveyed using the lifting platform in a vertical direction to the intended level in each case. Once it has reached the intended level, the transporting wagon is freed from the lifting platform and moved in a horizontal direction to the respective depositing space where the vehicle is pushed from the transporting wagon into its respective space. The construction of this known parking system is extremely expensive and a considerable amount of time is required for each individual parking and unparking operation.
A storing system of the type mentioned at the beginning is further known (DE-OS 1,811,635), which serves for loading and unloading sets of shelves using receiving troughs. The loading and unloading takes place using a chain drive, which can be driven in both directions and which can be coupled to the receiving troughs via swivel hooks. Such a storing system is suitable only for a simple stored material, for example iron bars.
The object of the invention is to provide a storing system which can accommodate even large and sensitive objects with a high degree of accuracy and reliability and enables a rapid loading and reception at a small cost.
According to the invention, this object is achieved in that movable transport pallets for carrying the objects to be stored are guided on the roller rails, in that at least one transfer device is arranged on the receiving device between the roller rails to move the respective transport pallet during transfer and to secure the transport pallet during the conveying on the receiving device, in that at least on the underside of each transport pallet approximately centrally and running in its longitudinal direction, a guide rail is fastened, the part of which points downwards, and in that gripping wheels belonging to the transfer device are arranged on both sides of the guide part, can be applied against opposite sides of the guide part and lifted off from the latter again, and can be selectively driven and immobilized together.
In the storing system according to the invention, it is possible to transport the objects to be stored from different entry points to any desired depositing space and subsequently to different exit points. It is also readily possible to carry out a rearrangement of the objects from one depositing space to another depositing space. Both the horizontal and the vertical transporting movements are carried out with a single frame which can have a very simple construction. By superposing the horizontal conveying movement and the vertical conveying movement, the objects can be conveyed within the storing system by the shortest direct route from space to space. Since the objects are conveyed on transport pallets, on which they remain in the depositing spaces as well, it is possible
