Abstract
A material storage and handling system has a transfer vehicle and a stacker vehicle. The transfer vehicle is adapted to receive and carry the stacker vehicle and the stacker vehicle is adapted to carry and transfer material between the transfer vehicle and selected bins in a multiaisle, multibin storage structure. The stacker vehicle has an elevator with a laterally movable platform for moving material into and out of the bins. The position of the elevator to the bins is sensed by reed relays on the elevator that sense magnetic strips on the elevator superstructure that are coded to indicate respective bins. To pick up or deposit the material when the lateral platform is extended, the reed relays are selectively raised or lowered a small amount to effect a vertical shift of the platform for picking up or depositing material.

Johnson and Lewis J. Lamm ABSTRACT: A material storage and handling system has a transfer vehicle and a stacker vehicle. The transfer vehicle is adapted to receive and carry the stacker vehicle and the stacker vehicle is adapted to carry and transfer material between the transfer vehicle and selected bins in a multiaisle, multibin storage structure. The stacker vehicle has an elevator with a laterally movable platform for moving material into and out of the bins. The position of the elevator to the bins is sensed by reed relays on the elevator that sense magnetic strips on the elevator superstructure that are coded to indicate respective bins. To pick up or deposit the material when the lateral platform is extended, the reed relays are selectively raised or lowered a small amount to effect a vertical shift of the platform for picking up or depositing material.

Claims (11)
1. A material handling apparatUs comprising: a structure forming a plurality of vertically arranged bins; an elevator vertically movable relative to the structure having a platform laterally movable into and out of the bins for selectively depositing a load in a bin or withdrawing a load from a bin; a drive means for vertically moving the elevator and laterally moving the platform; control means including a sensing means for selectively producing a signal when the elevator is at depositing or withdrawing positions opposite a selected bin in the structure; said control means being connected with the drive means and responsive to the signal for controlling the drive means to stop the elevator selectively at an upper vertical position for depositing a load or at a lower vertical position for withdrawing a load, said control means also including sequence means for causing said drive means to move said platform laterally into the bin when one of said vertical positions is reached, shift means connected with the sensing means to cause the drive means to move the elevator to the other of said vertical positions when the platform reaches its inward position, said sequence means causing said drive means to move said platform laterally out of the bin when the elevator reaches the other of said vertical positions.
2. A material handling apparatus according to claim 1 wherein said sensing means comprises signal initiating devices mounted at selected positions relative to respective bins, and a responding device mounted to move with the elevator and having a sensor adapted to coact with a signal initiating device for producing the signal with said signal indicating that the elevator is opposite the selected bin in said upper or lower position when said sensor of the responding device is adjacent the signal initiating device corresponding to the selected bin; and wherein said shift means is operatively connected with the responding device and adapted to effectively move the sensor of the responding device in a vertical direction relative to the elevator.
3. A material handling apparatus according to claim 2 wherein said signal initiating devices are coded groups of elements of magnetic material selectively positioned near respective corresponding bins and said responding device is a group of sensors in the form of magnetically responsive reed relays.
