Reel loading and unloading system ARL

automatic

Modern rotogravure presses with rolls weighing up to 7 tons require extremely accurate and stable transfer stage with integrated lifting device. The new, fully prepared roll arrives at the wait position directly in front of the reelstand. The automatic cycle for the loading is initiated by the splicing action. In a first step the core or past-used roll is taken directly from the reelstand arm by means of a Monorail core clamp. The new roll is positioned in the middle of the transfer stage. Then the platform travels to the pre-centering axis and lifts the roll. A photocell in the pre-centering device stops the lifting. Now the centering arm function commences. The centering cones are synchronously inserted into the core. Height deviations are corrected by the fine height adjustment. The fine height adjustment also permits the equalising of height differences left and right. The integrated slewing rail permits accurate lateral alignment of the roll. Once the roll is aligned, the position is blocked, the transfer stage runs to the load position and transfers the roll to the reelstand.
