Abstract

Normally when a part is to be picked by a robot from a parts feeder, the robot first fetches a required tool from a remote tool holder and then moves the tool to the parts feeder to pick up the part and lastly place it. The arrangement disclosed allows both tool and part to be picked up at the same time, thus reducing the number of moves required by the robot. A vacuum tool is supported by a tool holder above a part waiting to be picked from a parts feeder. When the robot requires the part, it moves to above the tool and then engages and depresses the tool to pick the part. This depression feeds the next component forward from parts queued on a conveyor to a stop.

Parts Handling by Robot

Normally when a part is to be picked by a robot from a parts feeder, the robot first fetches a required tool from a remote tool holder and then moves the tool to the parts feeder to pick up the part and lastly place it. The arrangement disclosed allows both tool and part to be picked up at the same time, thus reducing the number of moves required by the robot. A vacuum tool is supported by a tool holder above a part waiting to be picked from a parts feeder. When the robot requires the part, it moves to above the tool and then engages and depresses the tool to pick the part. This depression feeds the next component forward from parts queued on a conveyor to a stop. When the tool, together with the original part, is removed by the robot, the next part slides to replace the original part whilst the next succeeding part is held by a friction pad. The figure illustrates the parts-handling arrangement. A special vacuum tool 1, suitable to be picked up by a robot, rests in a hole through tool holder 2 supported by two spring-loaded pillars 3 adjacent to its ends so it has vertical compliance. A sloping rail 4 of a parts feeder terminates at its lower end to support a part 5 in a pick-up position directly below, but spaced from, tool 1. The next part 6 to be fed is held in a position remote from tool holder 2 by a friction pad on spring stop lever 7. Behind part 6 is part 8 at the head of a parts queue on conveyor 9. To pick tool 1 with part 5, th...
