DOPAG has recently released new dispensing valves. These valves are for use in all industries processing low- to high-viscosity liquids, such as lubricant, adhesives or epoxy.
In a series of videos released by DOPAG, Michael Wortmann, Director Automation Technologies, and Thomas Müller, Product Manager, present a production cell for automated greasing. It is equipped with a 6-axis articulated robot. A spray valve and a shot valve apply grease to plastic gearwheels. The robot picks up the gearwheel from a work-piece carrier and takes them to the installed valves, before putting them back in the work-piece carrier.
The gearwheel is greased both inside and out by the two valves. For interior greasing, the spray valve, combined with a round jet nozzle and a gear flow meter, ensures full-surface material application. For the exterior greasing, the material is applied punctiformly to the sides of the gearwheel.
Both valves are supplied with material via a 30-litre lubricant pump from the lubriLine product line. Three material pressure regulators ensure a constant working pressure during the metering and mixing process.
