Drive
System
This new drive system and infeed timer screw mounting arrangement offers the following benefits:
- Reduced change over time due to memory position indicators for exact and repeatable setup.
- Tool-less, quick change fasteners to support operator changeover.
- Flexibility to run numerous container sizes and shapes given vertical and horizontal adjustment.
- Elimination of center guide notching for new containers that were not part of the original project scope.
- Reduced maintenance costs resulting from the new drive system technology.
For more information on this new technology or inquiries on how to convert an existing Pacific filling system, please contact Jerry Carpino at (949) 369-2425 or information@pacificpak.com.

Lead-Time
& Cost
Savings
- 9-Station, Light to Semi-Viscous Filling Machine:
Ideal for large size containers (32-oz. to gallon) that require positive shut-off nozzles to control drip. Speed range of 30 to 90 C.P.M. based on the volume and container opening. Supports a maximum container diameter of 7.500". - Reconditioned Frames:
The frames are reconditioned to like-new condition. The top deck is constructed from 304 stainless steel. The lower frame is steel with multiple coats of Steel-It paint. If this arrangement is feasible for your new filling machine configuration, we offer a $7,500.00 discount.

On
Stop-Start
Operation
In our last issue, we discussed how to address under fills (see the under fill technical tip). In this months issue, we address over fills during stop-start operation.
If this is something you experience, use the following list of potential causes and solutions to troubleshoot and easily adjust the filling machine back to its original operating condition:
- The time-delay for the turret start rotation is too long. This allows the fill nozzles
to drip/drain before the filling turret starts to rotate.
Solution: Decrease the time in seconds on the relay-timer (non-PLC fillers) or the HMI Configuration Screen (PLC fillers) to ensure the turret starts to rotate right after all the fill nozzles are fully open. - The time-delay for the nozzle close on a machine stop is too long. This allows the nozzles to
drain after the turret comes to a complete stop.
Solution: Decrease the time in seconds on the zero speed timer (non-PLC fillers) or the HMI Configuration Screen (PLC fillers) to ensure that the filling nozzles close as soon as the filling turret comes to a complete stop. - The turret ramp up and ramp down speed is too gradual.
Solution: Set the turret drive acceleration and deceleration time to 2 seconds or less. Note that the turret acceleration and deceleration times should also be set to the same value. - For an individual station (or stations) that are always high, the filling nozzle or plunger
is not operating properly.
Solution: Re-gauge the plunger stroke. If this does not solve the problem, replace the plunger and/or filling nozzle. If the problem still persists, rebuild the air cylinder. - One or more filling nozzles within the fill zone do not open before the machine starts to rotate or close
after the machine stops.
Solution: Ensure that the fill valve air regulator is set to at least 30 PSI. Also confirm that the air manifold, air cylinder lines, and air cylinder seals are not leaking excessively. Finally, confirm that the 4-way valve and solenoid are in good working order. - There is excessive pressure at the inlet of the filling turret.
Solution: Ensure that the drive system is in good operating condition and that the pump does not continue to run once the filling turret stops and the valves close. - The product tank level is too high (Only applies to low viscosity products).
Solution: Install a tank level sensor and configure to maintain a tank level of +/- 6" or better. - Erratic rotation of the filling turret.
Solution: Verify the main spindle bearings are in good condition. Inspect the filling turret drive system for worn parts. - Erratic rotation of the pump.
Solution: Verify that the pump and the pump drive system are good working condition.
Also note that many of the above items can be added to your semi-annual preventative maintenance check lists in order to ensure that your filling machine does not produce over fills on stop/start operation.
