MININDEX 1. MINIATURE INTERMITTENT MOTION ASSEMBLIES Miniature assemblies Standard configurations are normally a mechanical intermittent motion box complete with worm geared 3 phase asynchronous motor input. A microswitch assembly is used for stop/start cycle-on-demand operation in cam dwell period only. Housings are made of aluminium alloy, except IR201. The intermittent mechanisms Standard configurations are cam profiles which have symmetrical accel/decel phases and use modified sinusoidal motion law. Input rotational sense reversal produces corresponding output rotational sense reversal....

Without overlap Standard movements can be used with both continuous and intermittent operation. Stop periods in the represented cyclograms have been programmed in points 1 and 4 only for example purposes. Dwell periods can usually be positioned in each one of the single points 1,2,3,4,5,6. Reversing the direction of rotation of the input shaft on the manipulator causes a reversal of the chronological sequence of cycle...

7. MICRO GROUPS In many applications that need the use of INDEX DRIVES a limit switch cam is used necessarily to stop the motor at every cycle end. When the application calls for stopping the motor at each cycle, either to prolong dwell times or to reverse the direction of rotation, a limit switch can be used for that purpose. The limit switch cams mounted on the cam shaft, are made in three standard shapes, each one suited to the type of limit switch used. Such cams are catalogued as shown below. • ATTENTION: the phase cam is not a safety device. Keyed to the opposite side of the reducer....
