When Fill Stations Under or Over Fill
One of the many unique features of a Pacific filling machine is the ability to set both the upstroke and downstroke on individual filling stations. To ensure accurate fills, the plunger upstroke and downstroke should be the same at each station.
Every filling machine is shipped factory set and usually requires no adjustment for a long period of time. If fill stations are consistently under or overfilling, use the recommended procedure below to gauge the stroke:
- Turn the machine air ON. All filling nozzles should be in the closed state.
- Loosen the air cylinder nut (away from the coupler) with a 3/4″ wrench.
- Turn the coupler such that the end of the plunger stem extends 1/16″ beyond the end of the fill tube.
- Tighten the air cylinder nut. The “downstroke” is now set.
- Repeat at all filling stations.
- Turn the machine air OFF.
- Reverse the air manifold “Pressure” and “Exhaust” lines.
- Turn the machine air ON. All filling stations should now be in the open state.
- While holding the stroke screw on top of the air cylinder with a 7/16″ wrench, loosen the upper nut with a 3/4″ wrench.
- Insert the proper end of the gauging tool into the fill tube.Important Note: Use the 1/2″ length side for thin products and the 11/16″ side for thicker products.
- Adjust the stroke screw clockwise or counterclockwise until the gauge shoulder touches the fill tube tip.
- Tighten the stroke nut while holding the screw in place. The “upstroke” is now set.
- Turn the machine air OFF.
- Return the “Pressure” and “Exhaust” lines to their original positions.
If after gauging all the filling stations, you experience inaccurate fills, turn to the “Troubleshooting” section of your Operators Manual or call Pacific for advice.
