Plan accepted finished packs, not catalogue fill cycles.
Auger filler output should be planned from the complete repeatable production cycle: powder feed, dosing, settling, pack presentation, weight checks, closure or sealing, rejects, refills, stops and changeovers. The slowest controlled step sets the sustained line rate, so a filling-head cycle figure cannot be used as a finished-pack guarantee without an application trial.
Technical guidance by Lancing Ltd. Final output is application-specific and should be confirmed using representative product, production packs and an agreed trial or acceptance method.
Separate dose cycles, accepted packs and shift capacity.
| Term | What it measures | Why it can differ |
|---|---|---|
| Fill cycle | One programmed auger dosing sequence. | It may exclude pack loading, weight checking, settling, closing and rejected packs. |
| Mechanical rate | The maximum machine motion rate under stated test conditions. | It can exceed sustainable production when product feed or downstream equipment is slower. |
| Finished-pack rate | Packs filled and closed per minute under the agreed operating method. | Manual handling, seal dwell, capping, coding and inspection are included. |
| Good-pack rate | Accepted packs after the defined quality checks. | Rejects, rework and holds reduce the rate even when the filler keeps cycling. |
| Hourly output | Accepted packs produced during a measured operating hour. | Includes normal minor stops, refills and checks only if the test method says so. |
| Shift capacity | Accepted production over a complete planned shift. | Changeovers, cleaning, breaks, material supply, maintenance and planned downtime matter. |
Find the slowest repeatable operation before choosing the filler.
Hopper replenishment, vacuum or screw feeding, aeration and low-level behaviour can interrupt dosing.
Auger time, cut-off, dust containment and product settling determine when the pack can move safely.
Manual presentation, indexing, bag clamping, bottle stabilisation and change parts can set the pace.
Weighing, capping, sealing, coding, inspection, labelling and accumulation may be the actual constraint.
Build the target from demand and available production time.
Start with the number of accepted packs required, then divide by the net production time available after planned changeovers, cleaning, breaks and scheduled maintenance. Compare that required good-pack rate with a measured trial rate that includes the same operating tasks.
Required good-pack rate
Accepted packs required ÷ net running minutes = required accepted packs per minute.
Net running minutes should not include time already allocated to recipe changes, line clearance, cleaning, breaks or other planned work.
Measured sustainable rate
Accepted packs produced ÷ measured elapsed production minutes = demonstrated accepted packs per minute.
Record every included stop, refill, intervention and reject so that the result can be compared fairly with the production plan.
Test the events that change real output.
- Define the duty. Record fill weights, packs, target accepted output, operator tasks, shift pattern and downstream process.
- Charge the hopper. Establish a repeatable working level and the intended product-feed or refill method.
- Run start-up. Retain the first fills and setting adjustments rather than excluding them from the evidence.
- Measure stable production. Time consecutive accepted packs and record weights, rejects and interventions.
- Refill and restart. Include hopper replenishment, a planned pause and the first fills after restart.
- Complete the pack. Include weighing, settling, capping or sealing, coding and inspection that are part of the required output.
- Change format where required. Time tooling, recipe, pack-guide and cleaning work for the production mix.
- Agree the basis. State which events are included, the sample size, product batch and acceptance criteria.
Match automation to the recurring bottleneck.
| Observed constraint | Possible response | Evidence to gather |
|---|---|---|
| Operator pack presentation | Improve pack support or compare conveyor-indexed automatic filling. | Manual cycle times, ergonomic review, pack stability and target rate. |
| Frequent weight correction | Review weigh-assisted operation, feedback or an independent inspection strategy. | Sequential weights, density changes, correction frequency and scale method. |
| Hopper refills | Review hopper capacity, feeder arrangement and level-control strategy. | Consumption rate, refill time, post-refill behaviour and product aeration. |
| Dust or settling delay | Review outlet geometry, filling height, extraction and pack dwell. | Video, dust observations, rim or seal condition and safe transfer time. |
| Closing or sealing | Balance the capper, sealer or VFFS cycle with the filler. | Closure cycle, seal dwell, rejects and product contamination at the closure area. |
| Changeovers and cleaning | Prioritise tooling access, recipe control, spare change parts and campaign planning. | Product matrix, clean standard, change frequency and measured changeover time. |
Use model reference rates only with their documented conditions.
The compact LU-FM100S and LU-FM100B have documented reference cycle ranges, while the LU-FM710, LU-FM750F and LU-FM4A support different pack-handling and control routes. Those figures should be treated as starting points for an application-specific run, not as directly comparable universal outputs.
Questions buyers ask about auger filler speed and capacity.
How fast is an auger filler?
An auger filler does not have one universal speed. Output depends on dose volume, powder flow, auger geometry, hopper feed, pack presentation, settling, weight checks and downstream closing. A model's mechanical or fill-cycle range should therefore be converted into accepted finished packs through a representative timed trial.
Direct link to answerWhy is finished-pack output lower than the quoted fill-cycle rate?
Finished-pack output can be lower because the operator or line still has to position the pack, wait for powder to settle, check weight, close or seal the pack, handle rejects and refill the hopper. A fill-cycle number measures only the dosing step unless the quotation states otherwise.
Direct link to answerHow should shift capacity be calculated?
Calculate shift capacity from accepted packs per measured net production minute, then apply the actual net time available after planned changeovers, cleaning, breaks and maintenance. Do not multiply a catalogue cycle rate by the whole shift unless every excluded task has been accounted for.
Direct link to answerWhen does a multi-head automatic auger filler become useful?
A multi-head automatic auger filler becomes useful when an indexed line needs more dosing capacity than one head can provide without excessive cycle speed. The benefit is application-specific: container infeed, dwell, capping, labelling and inspection must all support the required balanced line rate.
Direct link to answerWhich events should be included in a capacity test?
Include start-up, stable production, hopper refills, planned pauses, the first fills after restart, routine weight checks, operator interventions, rejects and the required closing process. Also record the product batch, tooling, recipe, hopper level and pack format so the result can be reproduced.
Direct link to answerCan finished output be guaranteed before a product trial?
Finished output should not be guaranteed from catalogue data alone when powder and pack behaviour are untested. A responsible scope defines the target, the product and pack samples, the operating method, acceptance criteria and any conditions that remain to be confirmed during factory or site testing.
