| What is included | 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 |
Reference unit for this duty: the Accessory.
Run the device at the line rating, not at a demonstration speed, and count rejects with the device on and off. Acceptance at half speed hides the timing problem that appears in the first production week.
The specification sheet for the Conveying carries the figures quoted here.
Through an encoder on the conveyor, so the print position follows the actual speed rather than a set value. Without the encoder, the code stretches when the line accelerates and lands off-centre.
The same question is worked through from another angle in How Nitrogen Dosers Improve Beverage Taste and Quality.
A consistent cap, a correct chute angle and a hopper that is never empty. Most cap jams are the chute and the level, not the sorter. A low-level sensor that stops the line before the hopper empties prevents most of them.
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.
Because the hopper is sized for a shift rather than for the line rate, or because the elevator runs slower than the capper consumes. Size the hopper on caps per minute at the filler rating, with margin.
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.
A laser marks the surface and needs no consumable ink, but it needs a clear line of sight and a consistent bottle position. An inkjet prints on most surfaces and carries ink and solvent cost.
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.
