Automated weight measurement system

Abstract

The present invention is a method and apparatus which automates the weight measurement of a payload in conjunction with a roller bed based loading/unloading station. The apparatus is designed as a retrofit for an existing loading station and consists a stationary frame mounted underneath the roller bed loading station. The apparatus includes lifters which are raised by air cylinders or the equivalent upon activation to physically remove the payload temporarily from the roller bar station while the weight is measured through load cells arranged with the lifters. The engagement and release of the lifters as well as the reading of information from the load cells is coordinated and controlled by a microprocessor. Appropriate communication means are provided for, to enable the system to be activated, and to allow the weight readings taken to be incorporated into other payload management functions such as billing, receiving, inventory control, or other functions. The system is further characterized by visual or audible alarms to prevent the system from being overloaded and to signal to an operator when it is safe to remove the payload or place an additional payload on the roller bed.
