An analysis of built-in and optional induction cap sealer detection packages available to ensure your Unifoiler™ waterless induction sealer promotes 100% verified induction sealed products.
Sealing Unit Verification was coined by Pillar Technologies as a key factor for induction sealing reliability. The term SUV (sealing unit verification) refers to any feature or option Pillar extends on their Unifoiler™ waterless induction sealing systems that help ensure the system is sealing properly. The sealed product is verified by using the most technological systems available. Pillar’s SUV package may be composed of a combination of built-in or standard features, coupled with extremely detailed detection packages for ultimate verification.
Standard “built-in” SUV features of the Unifoiler™ include:
- Adjustable loss of seal alarm and conveyor shut down capabilities
- Diagnostic indicating lights that include alarm fault
- Impedance high or impedance low
- High temperature
- Current trip, under voltage trip, or over voltage trip
- LED displayed operator controls that show power, alarm set, total bottle count, rejected bottles, and alarm set points.
Optional SUV packages available may include:
- Missing foil/loose cap detection and count display with reject delay and duration control
- Stalled bottle detection and count display with zero conveyor speed sealer shutdown
- Total bottle count display and run time display with conveyor speed referenceb display
- Reject device with kick-off tray and reject verification confirmation
- Deluxe stacked indicating light package to detect coil field active, visual loss of seal indicator or induction sealer in stopped position.
- In-feed bottle stop halting any unsealed bottles from entering the sealing frequency area when power drops, machine is turned off or stopped unexpectedly.
STANDARD “BUILT-IN” SEALING DIAGNOSTIC INDICATORS OF THE UNIFOILER™ WATERLESS INDUCTION SEALER SERIES THAT HELP ENSURE A PERFECTLY SEALED BOTTLE: (These are all security safeguards in the equipment only that may assist in promoting 100% induction sealed products.)
Alarm Fault - Lights when the coil output has dropped below the threshold set by the alarm set point on the panel. This is used to indicate that the inverter is not supplying the desired power to the coil. In such a case, proper sealing may not be accomplished.
Impedance High - If this light should illuminate when the inverter is in Stop mode, it does not indicate a problem. If it illuminates while the inverter is running, there may be a problem inside the inverter or coil.
Impedance Low - Indicates that an impedance mismatch has occurred. This condition occurs when the load on the inverter is higher than it can deliver.
High Temp - Indicates that the power transistors inside the inverter are not receiving sufficient cooling. The inverter will shut down to prevent the unit from overheating.
Reject Fault – Indicates that the reject verification sensor did not sense a bottle moving into the reject tray.
Current Trip - Indicates that a short circuit has occurred between the inverter and the coil.
Under Voltage Trip - Indicates that the supply voltage to the inverter has dropped (as in a brownout). The inverter will shut down to prevent the inverter from drawing excessive current.
Over Voltage Trip - Indicates that a voltage surge or other situation has caused an overvoltage condition within the inverter. The inverter will shut down to protect itself.
Stalled Bottle Fault - When this light is illuminated it is a warning that a Stalled Bottle condition was detected at the sealing coil. Also lights when rejected bottle button is pressed.
Loose Cap Fault - When this light is illuminated, it indicates that a cap was detected which is not fully seated on the container or is not threaded evenly causing a fault condition. Also lights when rejected bottle button is pressed.
Missing Foil Fault - When this light is illuminated, it indicates that a container passed under the sealing coil that did not have a liner installed, and was not properly sealed.
Zero Speed Fault - When this light is illuminated it is a warning that a Zero Speed Condition was detected at the conveyor.
Alarm Set - Pressing this button allows the operator to view the Alarm Set Point on the display and change as required.
Total Bottle - Indicates the total number of containers that have passed through the sealing coil. (Not available without the optional detection system.)
Rejected Bottle - Indicates the total number of rejects due to a stalled bottle, loose cap, or missing foil fault. (Not available without the optional detection system.)
Total Run Time - Indicates the total number of operating hours on the system. Power Set Point - Digital entry of the percentage of output power. This setting will control the amount of heating induced in the bottle caps.
Alarm / Time Set Point - Digital entry of the alarm threshold. If the actual power output to the coil falls below this setting, the alarm circuitry will be activated. This is sometimes called the “loss of seal” condition.
