Several types of devices can realised rotary manipulation.
BRMT (BRMT2 and BRMT3) are mechanical units which, by means of two barrel cams turn the uniform rotating of the inlet shaft into an intermittent angular and vertical stroke of the output turret.
The angular stroke (i.e. the intermittent rotation or oscillation of the arm) and the vertical stroke (that is the lift and descend of said arm) follow each other and are in phase with the application cycle.
BRMTs angular stroke is normally 90° or 180° (other angles can be realised on request), while the vertical stroke ranges from 25 mm to 100 mm.Speed can reach 120 cycles/min; as usual the less the masses.
Manipulators MAP (MAP 85, MAP 110 and MAP 135), delivering the intermittent rotation of the turret through an output device cam flat, and its lifting by a cam drum.
The manipulator MAP allows a different balance of the phases of rotation is up, allowing to reach very high working frequency (200 rpm) with 180 ° rotation of the arm without multiplication of the rotation.
