| Supply scope | Printers, coders, cap feeders, nitrogen dosers, detectors |
| Function | Support the filler without changing its rating |
| Key control | Position, timing, consumable cost |
| Integration | Signals from the filler PLC or a standalone sensor |
| Key decision | Whether the device earns its cost per 1,000 units |
| Typical position | After the filler, before the packer |
Support equipment does not raise the filler rating. It removes a manual task, a reject source or a compliance risk. The test is simple: if the device stops, does the line stop, and does the defect rate rise? If neither, it is a convenience rather than a control.
Position follows the signal. A coder needs the bottle presented at a fixed gap; a cap feeder needs a buffer before the capper; a detector needs a clear view and a reject gate downstream. Moving any of them changes the timing and the reject logic.
| Device | What it controls | Consumable |
|---|---|---|
| Coder or printer | Date and batch code | Ink, solvent or laser power |
| Cap feeder | Cap supply to the capper | None, but a buffer is needed |
| Nitrogen doser | Headspace oxygen | Nitrogen per 1,000 units |
| Fill level detector | Reject decision | None, but a reject gate is needed |
Site requirements, air and power consumption sit with the Accessory.
Ink, solvent, laser power, nitrogen, caps and labels all carry a per-unit cost that does not appear in the machine price. A device with a low purchase price and a high consumable cost can be the most expensive item on the line over five years.
The unit behind this configuration is the Conveying.
Either through a discrete signal from the filler PLC, which is simple and reliable, or through the line network, which allows recipes and reporting. Discrete signals are easier to commission; network integration is easier to audit. Choose based on who will maintain it.
The same question is worked through from another angle in CO₂ Laser Printer for Bottling Lines.
A coder applies variable data such as a date or batch code. A labeller applies the product label. Both sit on the conveyor, but only the labeller carries brand and legal product information.
Yes, with a reject gate and a shift register that tracks the bottle from the sensor to the gate. Without the register, the gate rejects the wrong bottle.
Caps arrive out of orientation, the elevator runs faster than the chute can release, or the chute angle is wrong for the cap. Most jams are a chute and speed setting, not a cap defect.
Between the filler and the closure, close enough that the gas stays in the headspace. Moving it further downstream wastes gas and gives an unstable result.
