Abstract: A method and system for stacking coils in which a coil stacker lifting head can be used to raise one or more coils from a conveyor assembly. The coil stacker lifting head can be automatically actuated using a actuating cylinder and a counter balance cylinder. The coil stacker lifting head can include an expanding mandrel to grab opposite edges of the coil and lift the coil. One or more of the coils can be lifted from a conveyor assembly by the coil stacker lifting head. After the one or more coils are lifted, a carriage assembly can transport the lifted one or more coils to a desired position. Once the one or more coils reach the desired position, the one or more coils are lowered to a surface. Upon reaching the surface, the mandrel automatically collapses to release the one or more coils and the mandrel is released from the coils.

Abstract: A device for separating a sheet metal coil from a cylindrical constructed form of a plurality of coils interconnected by tabs, said device comprising a turnstile with a mandrel which removes the construct from a slitting line and turns it over towards a downender assembly. A portion of the downender assembly is inserted into a support arm holding the mandrel and the construct so that a part of the construct is secured by the mandrel and a second part is secured by the downender assembly. The two parts are separated when the mandrel is pushed up from the support arm by a lifting cylinder. After separation, the coil is turned into a horizontal position by the downender assembly for further processing.
