<p>PURPOSE:To enable safety conveyance into an automatic warehouse including shelves on which large and small cargoes are stored, respectively, after being discriminated from each other, by providing a cargo discrimination means for judging whether each cargo is large or small, to effectuate the conveyance into the warehouse on the basis of the result of the comparison of the output of the discrimination means and the size of the shelf on which the cargo is to be stored. CONSTITUTION:A cargo to be stored in a warehouse is transferred to a prescribed position on a conveyed-in cargo rest 8. If the cargo is a large one 10, both photoelectric switches 12, 13 are put in a state of cargo detection. If the cargo is a small one 11, only the switch 12 is put in the state of cargo detection. The outputs of the switches 11, 12 are applied to a cargo size discrimination circuit 16 so that judgement signals 21 are sent from the circuit to a comparison circuit 22, which compares the signal with a cargo size signal 20 based on a storage shelf position setting card 17 put in a card reader 18. Only when it is judged that the compared signals are coincident with each other, a crane operation permitting signal 23 is applied to a crane controller 19 to operate a crane 1 including a vertically moving carriage 5 and a fork 6 movable in and out, to place the cargo in the warehouse.</p> |
