ABSTRACT:
Automatic warehouse apparatus is provided according to the present invention wherein a digital remote control system is relied upon to control the operations of a remote stacker adapted to pick-up and deposit loads at a support containing a plurality of discrete storage locations. According to one embodiment of the present invention a support containing a plurality of adjacent columns of storage locations is provided with a plurality of electrical conductors in a manner such that each of the plurality of electrical conductors has a portion from which electrical information applied to that conductor may be derived positioned in relation to an individual one of such plurality of adjacent columns of storage locations whereby one of the plurality of electrical conductors is associated with each column of storage locations. Carrier information signals serving to designate each of the plurality of electrical conductors and hence the column of storage locations associated therewith are applied to the plurality of electrical conductors from a central control console according to a predetermined digital code and a remote stacker movable in front of the plurality of adjacent columns of storage locations is adapted to derive carrier information signals including at least a signal designating a selected one of the plurality of columns of storage locations from the aforesaid portions of individual ones of the plurality of electrical conductors. Additional carrier information signals including at least a signal designating a selected one of the plurality of columns of adjacent storage locations and the operation to be performed are also applied to the remote stacker from the control console. The remote stacker is provided with a device for comparing signals designating a selected one of the plurality of columns with carrier information signals derived from the portions of the individual ones of the plurality of electrical conductors and designating the column of storage locations associated therewith whereby the motion of the remote stacker may be stopped in front of the selected column of storage locations and the desired operation performed.
