ABSTRACT:
An electronics package for automatically inhibiting operation of the shear blades of an individual section glass machine is responsive to periodic signals from an encoder disc indicative of timing increments in a machine cycle and to motion detectors adjacent to the shear blades for detecting shear operation at the desired point in the machine cycle and for inhibiting shear activation in the absence of such operation. The lockout electronics package includes a programmable counter responsive to the cycle-increment signal for generating a first shear-inhibit signal in the absence of shear operation within the programmed number of cycle increments, and a watchdog timer responsive to the cycle-increment signal for generating a second shear-inhibit signal in the absence of a cycle increment signal above a preselected frequency. A solid state relay is responsive to either of the shear-inhibit signals for removing electrical power from the shear operating mechanism. The electronics package is responsive to an operator shear-unlock switch for reenergizing the shear activating mechanism independently of the counter and timer.
