Sheet Unloader The Crabtree Vickers semi-automatic oven unloader and stacker is designed to form part of a high-speed printing of coating line. The complete equipment comprises an extraction conyeyor,a centre conveyor and a sheet stacker, together with a built-in control panel. Capable of operating at speeds of between 6,000 and 7,500 sheets an hour, depending on size and material, and strongly constructed throughout for heavy duty service over many years of operation, the line will handle a wide range of tinplate or aluminium.
As the oven wickets move around the end sprockets of the oven and reach a horizontal position, the sheets are withdrawn by the belts of the extraction conveyor. They are then forwarded along the belts and on to the four-belt centre conveyor, a drop wheel and two bowing discs bowing them slightly as they move along the belts to assist transferto the stacker.
