Bottling Line Staffing Trial: How to Verify the Crew in a Supplier Quote
Verify the crew in a bottling line quotation by testing overlapping manual tasks, recording extra help and measuring accepted output.
Do not buy a bottling line on a quoted operator count alone. Ask the supplier to list the tasks that remain manual, then prove that the proposed crew can complete them while the line delivers the agreed number of acceptable bottles. A line can fill and cap automatically and still need someone to replenish caps, clear rejects or pack finished bottles.
Mark where the quoted line starts and ends
Put a boundary around the equipment on the layout. Does it start with loose empty bottles or bottles already placed on the conveyor? Does it end at labeled bottles, or does someone still need to pack them into cases? An operator count without these boundaries cannot be compared across quotations.
| Station or task | What to ask the supplier to show |
|---|---|
| Empty bottle loading | Who loads bottles, how often, and what happens during a refill? |
| Filling | Who replenishes product and checks the first acceptable bottles after a stop? |
| Capping | Who replenishes closures, and which cap placement steps remain manual? |
| Labeling | Who changes rolls, checks label position and handles rejects? |
| Discharge | Who removes finished bottles or packs cases, and what happens if they fall behind? |
Test tasks that happen at the same time
During the factory trial, have the proposed crew run representative bottles, caps, labels and product or an agreed substitute. Record accepted bottles, stops, rejects and every manual intervention. Include a cap refill, label-roll change and controlled restart. If one person is supposed to cover two stations, test what happens when both need attention together. Note any help provided by the supplier's technicians separately; that help should not silently become part of the quoted staffing level.
Compare two layouts with the same work included
Before the trial, agree the crew size, observation period, included tasks and minimum accepted output. During the run, record each intervention with its time, station, assigned operator, minutes of interruption and any extra help. If the crew needs an extra person during overlapping tasks, record that separately and ask the supplier to revise the staffing assumption or demonstrate a different arrangement. Do not count a short demonstration with technicians helping as proof that the quoted crew can run a full shift.
Use the ZXSMART complete packaging line as the configuration starting point. If the quotation includes an automatic capping machine, confirm cap feeding and replenishment in writing rather than assuming every closure is handled the same way. For a compact alternative, compare the small-bottle filling and capping monoblock only where the bottle and closure sequence fit; check what still happens outside the machine.
Frequently asked questions
Can one person run the entire line?
There is no universal answer. It depends on the quoted equipment boundaries, refill frequency, inspection, packing and whether tasks overlap. Ask for a trial at the proposed staffing level.
Should cleaning and changeover count?
Record them separately from steady running, then include them when estimating what one shift can actually produce.
Send your line requirements with your proposed crew, bottle and closure details, target accepted output and packing method.
Use this checklist alongside the factory acceptance test guide. Follow the supplier's safe operating procedures; never bypass guarding or interlocks to simulate a stoppage.
