Infeed
Define whether bottles arrive single-file, in trays/crates or manually. Confirm gap creation, back pressure, metering and the response when the washer cannot accept another bottle.
Line engineering guide
Bottle washing line integration and controls.
A bottle washer should be specified as part of the line: mechanically, electrically, operationally and through the utilities and drainage that support it.
Mechanical interface
Make bottle transfer predictable at every boundary.
Record conveyor height, direction, speed range, belt type, guide width, bottle pitch, accumulation and available straight length at the infeed and outfeed. Use the least stable bottle as a boundary case.
Inside the process
Confirm how the bottle is retained, inverted or presented to nozzles; where water can drain; and which change parts or guides control the bottle family.
Outfeed
Define the release pitch, residual water risk, inspection point, reject route, accumulation and transfer to filling, capping or labelling.
Controls interface
Agree the line states and safe responses.
| Condition | Information exchanged | Required response |
|---|---|---|
| Upstream starved | Bottle-present status or upstream-ready signal | Controlled pause without dry running or loss of process condition |
| Downstream blocked | Downstream-ready signal and accumulation status | Stop accepting bottles and retain/reject in-process bottles according to the agreed sequence |
| Water/air outside condition | Pressure, flow or quality alarm where monitored | Prevent unverified bottles passing as conforming |
| Guard or emergency stop | Safety circuit state | Safe stop and controlled restart; site risk assessment defines the safety function |
| Changeover/cleaning mode | Mode selection and permissions | Safe access, inhibited automatic movement and clear restart checks |
| Reject condition | Inspection result or process-deviation flag | Segregate affected bottles and preserve traceability |
The exact safety architecture and performance level require a competent machinery risk assessment; this guide does not replace it.
Utility responsibility matrix
- Water source, quality, pressure, flow and isolation
- Drain point, capacity, solids capture and discharge permission
- Compressed-air quality, pressure and connection
- Electrical supply, isolator and protective devices
- Extraction, ventilation or bunding where required by the process
- Who supplies and connects every service
Site-layout evidence
- Dimensioned plan and elevations
- Floor loading, level and drainage falls
- Doorways, lifting route and installation access
- Operator working zones and material replenishment
- Maintenance pull-out and component-removal space
- Cleaning access without contaminating adjacent operations
Test the complete sequence.
At FAT or SAT, include line states rather than only continuous running: start-up, bottle starvation, downstream block, utility alarm, controlled stop, restart, format change and cleaning mode. Record what happens to bottles already inside the washer so that potentially unverified containers cannot continue unnoticed.
Use the FAT guide to structure the test and the water and effluent guide to close utility responsibilities.
Send a line layout with the bottle brief.
A dimensioned sketch, equipment sequence, conveyor heights and desired control handshakes allow a much more useful integration review.
