1452686 Storage systems INVENTIO AG 26 March 1974 [2 April 1973] 13247/74 Heading A4T [Also in Division B8] Trollies 8 have platforms 12 raisable by inflatable bags 13, to engage a load and run on tracks 7 between a lift cage floor 3.1 and store shelves 4 over pivotable bridges 9. The drive for the trolley comprises a roller chain 15 constructed to resist buckling passing over chain wheels 16, 17 which can be driven in either direction by a motor 21 and through a guide 26 and a pivotable guide 27. The end elements 15À1, 15À2 of the chain engage an entrainment member 14 on the trolley by roller pins 15À4 entering slots 14À1, 14À2 and fingers 15À31 resting on members 14À3. Counterclockwise rotation of the wheels 16, 17 moves the chain and entrained trolley to the left, Fig. 1, until with the guide 27 moved to the position shown, the end element 15.1 disengages from the member 14 and moves through the guides 27, 26 while the element 15À2 remains engaged with the member 14 and due to the rigidity of the chain 15 extends out over the guide 27 until the trolley 8 is wholly on a shelf 4. After depositing the load reversal of the chain drive draws the trolley into the lift cage the guides 26, 27 guiding the end 15À1 of the chain into engagement with the wheel 16 and the member 14. |
