Filling Line Changeover Planning Guide
Changeover planning defines which guides, stars, nozzles, recipes, cap parts, labels and pack settings change between SKUs. External preparation and clear settings can reduce lost production without sacrificing verification.
Editorial basis
Planning guidance, not a final machine specification
Published by Allot Tech (Suzhou) Co., Ltd. This multilingual library uses a consistent buyer-decision framework and independently prepared language packs. Confirm the final configuration against supplier drawings, actual product and packaging samples, destination requirements and the signed technical agreement.
Direct answer
What this decision means for a real filling project
Changeover planning defines which guides, stars, nozzles, recipes, cap parts, labels and pack settings change between SKUs. External preparation and clear settings can reduce lost production without sacrificing verification.
This guide is part of the Capacity and Line Engineering cluster. Read the hub when the project still needs a broader comparison.
Changeover time, not just adjustment time
How long does a filling line changeover actually take?
A defensible quotation states the two formats being changed, the crew size, cleaning scope and when the clock starts and stops. A five-minute filler adjustment does not establish a five-minute changeover for the complete bottling line.
For a timed trial, agree to measure from the final accepted bottle of format A at the specified operating rate to accepted production of format B at its specified rate. Also record how long stable production must continue before the restart is accepted. This avoids treating one good bottle during repeated adjustments as completion.
Separate preparation that can safely happen outside the stopped interval from work that requires stopped and isolated equipment. This distinction follows the SMED changeover framework described by Vorne. Preparing a labelled change-parts trolley is different from reaching inside a running machine. Energy isolation, guarding and the approved cleaning procedure remain mandatory boundaries, not time-saving opportunities.
A 42-minute example for a bottle-format change
Illustrative planning example, not an Allot Tech performance guarantee: the same beverage changes from a 500 ml bottle to a 1 litre bottle. The following activities are sequential; no product-cleaning cycle is included. Actual measurements must come from the proposed machine, formats and trained crew.
| Activity | Minutes | Completion evidence |
|---|---|---|
| Clear the previous format and isolate as required | 5 | Remaining bottles accounted for; equipment released for the approved change procedure. |
| Change and set guides and format parts | 14 | Part numbers, guide settings and fasteners checked against the new format record. |
| Set filling and capping recipes | 6 | Recipe revision, fill quantity and closure settings verified. |
| Set label, code and packing format | 7 | Correct artwork, date code, label position and pack count confirmed. |
| Restart, inspect and demonstrate stable output | 10 | Agreed first-good-product and sustained-rate checks passed. |
Total stopped interval: 5 + 14 + 6 + 7 + 10 = 42 minutes. In an eight-hour shift with 30 minutes of other planned stops and two such changeovers, the remaining production window is 480 – 30 – (2 × 42) = 366 minutes.
If the measured accepted-output rate during that window is 40 bottles/minute, the planning output is 366 × 40 = 14,640 accepted bottles. This is not the same as multiplying 480 minutes by the machine nameplate speed. Any additional unplanned downtime lowers the result. A measured accepted-output rate already includes the quality losses in that measurement; do not subtract them again.
Where two teams work safely in parallel, use the elapsed critical path rather than adding both teams’ labour minutes. Where product change requires cleaning, cooling or sanitation release, include that complete sequence separately. A label-only change and an allergen-related product change must not share one assumed duration.
The format matrix
Which changes must the supplier demonstrate?
| Transition | Items to identify | Evidence before release |
|---|---|---|
| Bottle diameter or height | Guides, handling parts, nozzle height, sensors and conveyor transfer points. | Stable transport, no bottle damage, repeatable settings and correct filling position. |
| Cap or neck finish | Cap feed, chute, chuck and change parts; compatibility cannot be assumed. | Closure fit, application quality and agreed leak or torque checks. |
| Liquid or formulation | Contact parts, residue, seals, cleaning sequence and restart product condition. | Approved cleaning release and real-product filling checks; water trials alone may be insufficient. |
| Label, code or pack count | Artwork version, printer data, inspection recipe, collator and pack settings. | Correct finished pack and controlled removal of previous-format materials. |
What should a repeatable changeover record contain?
Record the A-to-B format pair, product, operator count, start/end times, task times, change-part list, recipe revision, cleaning release, startup rejects and accepted-output observations. Record B-to-A separately if the procedure differs. Preserve slower trials as well as the best run, so the production plan is based on repeatability.
For procurement, connect this timed record to the FAT evidence plan, the filling-head calculation and the comparable filling-machine quotation. Include format tooling, training and cleaning-related parts explicitly in the quoted scope.

Engineering inputs
Define the duty before comparing equipment
A useful proposal starts from agreed process and package information. These inputs keep suppliers from filling gaps with incompatible assumptions.
Send these details
- Complete SKU matrix
- Container and cap differences
- Label formats
- Cleaning between products
- Target changeover time
Require these checks
- List every change part
- Mark repeatable settings
- Time a representative change
- Verify first-good-product criteria
Line integration
Connect the choice to upstream and downstream equipment
A production line is limited by its constrained process, not the largest number printed on one machine. Upstream supply, filler cycle, closure handling, label and pack changes, accumulation and operator response should be balanced as one system.
Comparison sheet
Put every supplier on the same basis
| Decision area | What to state in the RFQ | What to verify |
|---|---|---|
| Product | complete SKU matrix | list every change part |
| Package | container and cap differences | mark repeatable settings |
| Performance | label formats | time a representative change |
| Operation | cleaning between products | verify first-good-product criteria |
| Project scope | Utilities, interfaces, documents, spares, packing, shipping and support | Written inclusions, exclusions and acceptance evidence |
Verification route
Move from a claim to recorded evidence
Agree on bottle size, product condition, sustained test duration, acceptable stops and quality losses. Record actual output at each section and identify whether short stops, starvation or blocking prevent the target from being sustained.
- Approve the duty, drawings and test conditions before fabrication is treated as final.
- Use production-intent product and packaging wherever they materially affect performance.
- Record results by format, operating condition and quality criterion rather than relying on a short edited video.
- List open items, owners and closure evidence before packing and again after site commissioning.
Buyer questions
Answers to common RFQ and acceptance questions
When is Filling Line Changeover Planning Guide useful?
Multi-format lines with several bottles, caps, labels or fill volumes. A supplier statement of quick changeover is not enough without a format matrix and timed procedure.
What details should be supplied before requesting a quotation?
Prepare the following project-specific information: complete SKU matrix, container and cap differences, label formats, cleaning between products, target changeover time. Drawings, photos and representative samples help the engineering review move from a budget assumption to a defined scope.
How should the proposed solution be checked before acceptance?
Use an agreed review or test plan to list every change part, mark repeatable settings, time a representative change, verify first-good-product criteria. Record the conditions, measurements and open actions so the result can be compared with the approved specification.
