Abstract
An apparatus and method for computerized control of a "Phillipsburg-type" mail insertion machine. The mechanical timing and drive mechanisms of the prior art inserter are replaced with a programmable computer, solenoid valves, and pneumatic cylinders, or other suitable drivers. The computer's software includes a plurality of programmed look-up tables. An operational delay look-up table includes electro-mechanical lag times for the pneumatically driven stations/sub-assemblies of the inserter. Also provided are look-up speed tables, which include start and stop angles for actuation of each of the pneumatic cylinders. A first look-up speed table includes actuation data appropriate for operation of the machine within a relatively slow range of speeds. Four additional look-up speed tables provide correct actuation data for successively higher speed groups, up to 10,000 insertion cycles per hour. An alternative method of determining actuation data is disclosed, requiring ongoing and updated calculations of appropriate values based precisely upon the machine's actual operational speed.
