Abstract
Abstract Storage system for products using supporting units, comprising a staging containing a number of storeys, on one side of the staging at least one supply-conveyor and at least one entry elevating device, which is movable in a longitudinal direction along the staging, as well as a device for the input of the supporting units into the staging and on the other side of the staging at least one exit elevating device, which also is movable in a longitudinal direction along the staging and at least one exit conveyor. In each storey of the staging one or more step conveyors are mounted, which at both sides of the staging are connectable with a single driving device, which is movable vertically on the entry elevating device and the exit elevating device respectively.

Claim 1
Independent Claim
351 words
A storage system for products using supporting units, comprising a staging containing a number of storeys, on one side of the staging at least one supply conveyor and at least one entry elevating device, which is movable in a longitudinal direction along the staging, as well as a device for the input of the supporting units into the staging and on the other side of the staging at least one exit elevating device, which also is movable in a longitudinal direction along the staging and at least one exit conveyor, characterized in that in each storey of the staging one or more step conveyors are mounted, which at both sides of the staging are connectable with a single driving device, which is movable vertically on the entry elevating device and the exit elevating device respectively and each step-conveyor consists of a supporting channel, which on its bottom is fitted with a row of fixed wedges with upwardly sloping surfaces, a lifting beam situated on top of the supporting channel which lifting beam is fitted with a row of movable wedges with their sloping surfaces reclined at an angle corresponding to the sloping surfaces of the fixed wedges and of a transport beam, which with its bottom surface contacts the horizontal top side of the movable wedges and wherein the driving device is movable parallel to the step conveyors in a carrying frame, which is movable up and down along the entry elevating device and the exit elevating device respectively and that one part of the driving device is connectable to the lifting beam and another part with the transport beam and wherein the driving devices consist of piston-cylinder combinations the piston-rod of each piston-cylinder-combination is connected with a gripper in which a search-opening is fitted and which is fitted with a latch disconnectable against spring force and that the transport beam, the lifting beam and a supporting beam of the supporting channel each are fitted with a coupling plate with an opening which by means of the latch is connectable with or disconnectable from the corresponding gripper of each piston-cylinder combination.
