ABSTRACT:
Objects to be inventoried are positioned on a series of platforms for weighing. Each platform, which may be a storage shelf, is supported on a piston operating in a fluid pressure cylinder, either hydraulic or pneumatic. On signal from a computer-controller, fluid is pumped through a common conduit into all cylinders simultaneously, steadily increasing the pressure on each cylinder piston. When the pressure reaches the point of balancing the combined weight of any one platform and the objects resting thereon, a signal is generated to report that balancing pressure value to the computer, at the same time causing the corresponding cylinder to be deactivated. Pumping of fluid continues until all platforms in the system have registered balancing pressure values into the computer. With data stored previously in its memory bank, the computer combines the reported pressure values with unit weights of stored objects, piston diameters, tare weights or weigh calibrations to calculate, store, display and/or print out an accurate count of the objects on each platform.
