Inker assembly including oscillation rollers for a can body decorator

An inker assembly having an ink cooling system for a can decorating machine, the inker assembly comprising:

• an ink well;
• plural laterally-fixed roller assemblies;
• plural oscillating roller assemblies including a first oscillating roller assembly and a second oscillator roller assembly;
• the oscillating roller assemblies and the laterally-fixed roller assemblies adapted for cooperation to transmit ink from the ink well to a plate cylinder of the can decorating machine;
• a cam system adapted for moving bodies of the oscillating roller assemblies laterally, the cam system including a cam body, a first cam follower, and a second cam follower;
• each one of the first cam follower and the second cam follower being engaged with the cam body;
• the first cam follower being coupled to a shaft of the first oscillating roller assembly, the second cam follower being coupled to a shaft of the second oscillating roller assembly;
• whereby operation of the cam body moves the shaft of the first oscillating roller assembly and the shaft of the second oscillating roller assembly laterally via the first cam follower and the second cam follower;
• and
• the ink cooling system including:
• a recirculating chiller adapted for transferring heat from a coolant;
• a temperature sensor located in and adapted for sensing temperature of a coolant outlet flow from the oscillating roller assemblies;
• and
• a valve and/or a pump adapted to control coolant flow rate during oscillation of the inker assembly to continuously flow the coolant through the inker assembly in response to data from the temperature sensor;
• wherein at least one of the oscillating roller assemblies is adapted for coolant flow therethrough to indirectly cool the ink.
