MPS 32 Tool Changer Adds 40mm To Robot Arm

The MPS 32 from Staubli's connectors division provides efficient and secure tool changes for all types of robot arms, reducing the need for investment in additional robots. Its compact size minimises any loss of daylight and adds 40mm to the robot arm. Increasing the utilisation and productivity of automated manufacturing cells frequently requires several operations to be completed by robots, all within the production cycle time.

The end of arm tools required during the cycle can range from drilling or grinding heads to grippers or gauges. Additional operations usually require additional robots; but with the facility to quickly and automatically change the tools on a robot arm, the need for a second or even third robot is eliminated, reducing the capital investment required, improving payback and often reducing the overall cell footprint. Staubli's range of automatic tool changers are specifically designed for these types of applications and the introduction of the MPS 32 extends their benefits to installations using smaller, lighter-weight tooling in compact cells.

All are directly mountable on the robot flange and provide secure locking and unlocking. Staubli's tool changers now extend from 32kg right up to 630kg tool-weight capability and in many applications have performed successfully for more than one million connection cycles. The MPS 32 is a compact unit, measuring 63mm diameter and 40mm wide, and both robot-side and tool-side elements together weigh only 0.7kg. It can handle payloads up to 32kg, operating within a pressure range of 4.5-10.0 bar.

The locking unit is a double active, pneumatically actuated system that ensures secure retention of the tool; additional internal springs make certain that the tool is securely held by the changer even if the pressure drops. All systems required by the tools are connected automatically, employing the technology used in Staubli multi-coupling plates; fluid lines; signal connections such as required for actuators, sensors, bus systems or fibre optics; and power connections are automatically connected to the tool and disconnected without any loss of fluid or ingress of air into the circuits.
