Failsafe module for coupling input and output members
A recently granted patent (Publication Number: US11920697B2) discloses a failsafe module designed to ensure the safe operation of machinery or equipment. The module comprises an input member, an output member that can move towards and away from a predetermined position, and a coupling mechanism that includes an intermediate member, an energy storage device, and a latch mechanism. The energy storage device is energized by the movement of the intermediate member relative to the output member, and the latch mechanism prevents or allows relative movement between the two members, thereby coupling or decoupling the input and output members. The module also features a clutch assembly that facilitates the coupling of the input and output members when the latch mechanism is engaged, ensuring the safe and controlled operation of the machinery.
Furthermore, the failsafe module includes additional features such as a drive arrangement between the intermediate member and the output member, multiple energy storage devices for applying torque, and a safety mechanism with an interlock mechanism to prevent relative rotation between components. The module is housed in an outer housing, and an actuator with a drive mechanism is mounted to engage with the input member for rotational movement. The design of the module ensures that the input and output members remain securely coupled during operation, with mechanisms in place to prevent unintended disengagement. Overall, the failsafe module described in the patent aims to provide a reliable and secure mechanism for controlling the movement and operation of machinery, enhancing safety and efficiency in various industrial applications.
