<p>A conveyor cam adjusting apparatus permitting adjustment of the radial position of each cam (30) on a drive shaft (32) while it is rotating. A plurality of individual electric motors (44) are mounted for rotation about a common drive shaft each motor being associated with a single cam. Each motor is provided with a means (140, 142) for manually selectively connecting it to a control means (144, 150) in order to enable an operator to rotate the associated cam relative to the common drive shaft while the shaft is rotating. A sensing means (150) may be used to detect the position of each cam relative to a predetermined reference position and the output of the sensing means may be used by a computer control means to automatically selectively activate each motor to adjust the associated cam accordingly.</p> |
