NEXEN AIR CHAMP SERVO BRAKES APPLICATIONS Eclipse Servo Brake on a Gantry System In emergency stop situations, heavy loads need to be stopped safely and quickly in a controlled manner. These are the issues a major designer and builder of robotic gantry systems had when they came to NEXEN. The customer manufacturers overhead "pick and place" robots and conveyor systems to move products throughout a factory. The robotic arm rides along the gantry system, picking up and stacking a variety of products onto pallets. The pallets are then moved along by a series of conveyors. The "pick" device (end effector) could be vacuum or mechanical in nature and operates in the X, Y and Z axes. The customer was using electric brakes mounted between an Indramat motor and NEMA-flanged worm gear reducer. Prior to installation, the customer needed to modify each brake by designing special flanges to accept Indramat MKD112, MKD090 or MKD071 motors and mount onto a NEMA- flanged gear reducer. Additionally, these modified brakes could not absorb the energy produced by each stop and failed to perform adequately on subsequent stops. This problem was solved by installing the Eclipse Servo Brake. Eclipse utilizes a flange-mounted design that includes so many options it can fit virtually every servo motor. Out of the box, the Eclipse solution can be mounted between the servo motor and the NEMA-flanged, worm gear reducer on the lift and rail systems of the gantry robot. The output end of the size 4 and 5 Eclipse brakes are supplied with a NEMA shaft, pilot flange and bolt circle to mount directly to 56TC or 145TC worm gear reducer. Both input and output flanges have slotted bolt holes that allow easy bolt installation and provide a range of bolt circle diameters. back to Eclipse applications page
