<p>PURPOSE:To automatically control a crane to correctly manage warehousing and delivery by a method wherein difference between the number of articles to be warehoused and the number of articles to be delivered is compared with a specified reference value and a command for switching over the modes is given according to the quantity of the difference. CONSTITUTION:With respect to a warehousing conveyer 12, a warehousing conveyer control processor 14 which detects the number of palettes to be conveyed is provided, and with respect to a delivery conveyer 13, a delivery conveyer control processor 15 which detects the number of palettes to be taken out from a specified shelf of a storage 10 is provided. An auxiliary memory 16 memories a signal detecting the requested number of articles to be warehoused from the warehousing conveyer control processor 14 and a signal detecting the requested number of articles to be delivered from the delivery conveyer control processor 15, and information of this auxiliary memory 16 is output to a crane control processor 17. The crane control processor 17 takes the difference between the requested number of articles to be warehoused and the requested number of articles to be delivered memorized in the auxiliary memory 16, and according to the quantity of the difference, it controls a crane 11 by switching it over the warehousing mode and the delivery mode.</p> |
