Abstract
A sleeve station dedicated to the assembly of a sleeve and a mandrel for a flexographic press. The sleeve station can be loaded manually, and assembles the sleeve with the mandrel in a vertical orientation when both are in a vertical orientation with aligned axes, avoiding problems caused by the bending of the sleeves during assembly. After loading of the sleeve, it is returned to a horizontal axis orientation.
Claims7
A module for replacement of a sleeve to be slipped on a mandrel for a rotary printing press, the module comprising,
- a sleeve gripper configured to secure the sleeve;
- a mandrel gripper configured to secure the mandrel;
- and
- a linear guide,
- wherein the mandrel gripper is configured to rotate, while securing the mandrel, from a sleeve replacement position, in which a revolution axis of the sleeve coincides with a revolution axis of the mandrel, together defining an assembly axis, to a delivery position in which the mandrel is transverse to the assembly axis;
- and
- the linear guide is engaged with at least one of the sleeve gripper and the mandrel gripper;
- and
- the linear guide is configured to translate the at least one of the sleeve gripper and the mandrel gripper substantially along the assembly axis,
- wherein the module is configured to position the mandrel with the sleeve to a printing position for a printing mode such that the revolution axis of the sleeve is substantially perpendicular to the assembly axis.
