Latest Patents

One of his latest patents is a "Conveyor system including a buffer store." This innovative system allows for the temporary retention of articles delivered by the conveyor to the store. Articles are raised out of contact with the conveyor by two ramps, which pass under a flange on each side of the article. The conveyor and ramps are designed to be downwardly inclined, allowing the article to travel along the ramps under gravity until it hits a stop. The system is designed to separate the articles into two parts, with the upper part being removed by a robot, while the lower, reusable part is returned to the conveyor. Additionally, a second stop is provided to permit the return of only one article base to the conveyor. Sensors are included to detect the presence of articles in the store.

Another significant patent is the "Gravity feed chute." This chute is designed for gravity feeding a plurality of like electrical components to a pick-up station of a robotic controlled automatic assembly system. It comprises guide rails down which components slide, with their pins extending between the rails. The rails are shaped to provide a downwardly inclined straight track leading into a horizontal track that comprises the pick-up station. The transition from the inclined track to the straight track is smooth yet abrupt, ensuring that the next component is successfully fed from the inclined to the horizontal section of the chute each time its predecessor is removed from the pick-up station. The design guarantees accurate positioning of the component in the pick-up station for access by the robot.
