Abstract
Workpiece monitoring and control apparatus for a machine having a desired predetermined sequential flow of equally spaced-apart workpieces therein and being characterized by continually monitoring both the presence and absence of workpieces in such flow and operating control mechanisms for such machine, such as stopping operation of the machine or actuating a signalling device, in the event of an undesired absence or presence of a workpiece. The monitoring and control apparatus includes an electrically operated machine control device, sensing devices positioned in the sequential flow of the equally spaced-apart workpieces for sensing the passage of workpieces and for sensing the absence of workpieces in such flow and an electrical circuit connected with the control devices and with the sensing devices for normally supplying electrical energy to the control devices and being responsive to the sensing devices for stopping the supply of electrical energy to the control devices when the sensing devices (1) fail to sense a workpiece in each desired equally spaced-apart position in the sequential flow or (2) fails to sense the absence of a workpiece between such desired position.
