Speed
20–60 bottles/min
Automatic Series
A pneumatic inline automatic screw capping machine for production lines that need a stronger balance of throughput, repeatability and flexibility. It handles screw caps, spray caps and pump caps with adjustable guides and stable torque control.

Machine overview
Inline automatic capping machine for spray bottles, pump closures and general screw caps.
20–60 bottles/min
18–70 mm caps
20–160 mm bottle diameter
Designed for continuous production after filling and before labelling.
Guides and clamps adapt to different bottle styles.
Automates start/stop and improves consistency.
Can integrate with a bowl or elevator where required.

Technical selection
This platform brings bottle detection, inline handling and automatic capping into one controlled cycle. It can be considered when manual tightening is no longer consistent or when the capper must sit between filling and labelling. The final system still depends on whether an operator places each cap or an automatic feeder presents it.
The supplied page lists bottle height from 30–300 mm, bottle diameter from 20–160 mm, cap diameter from 18–70 mm and working speed from 20–60 bottles per minute. Working pressure is listed at 0.4–0.6 MPa and the approximate machine size is 1930 × 740 × 1600 mm. A cap bowl or elevator is optional. These figures must be confirmed for the actual bottle, closure, feed method and line layout.
Automatic tightening cannot correct a cap that arrives tilted, reversed or on the wrong thread start. For manual placement, confirm the operator can sustain the target pace safely. For automatic feeding, test cap nesting, orientation, chute handover and placement on the moving or indexed bottle. Specialist feeder selection belongs with Cap Feeders UK.
Guides and fixtures should support the container through detection, cap engagement and tightening. Tall, flexible or lightweight bottles may need additional support. Agree the finished cap height, application or removal torque method, liner and tamper-feature condition, leakage or closure-integrity check and acceptable cosmetic result.
Record the approved guide positions, head height, tooling, sensor positions and speed for each format. The project scope should define line start/stop, queue signals, low-cap response, emergency-stop interface and recovery after a jam. Routine checks should include tooling condition, guide security, sensors, pneumatic supply and product contamination around the capping head.
Send all bottle and cap variants, filled weights, required output, batch pattern, cap-placement method, available floor space, conveyor height, line direction and upstream/downstream equipment. Use the cap feeder versus manual placement guide and line-layout review before finalising the scope.
Buyer FAQ
No. This page describes an automatic inline single-head/pneumatic capping route. A belt/spindle machine uses successive rotating contacts and is a separate option.
The supplied specification lists a cap bowl or elevator as optional. The correct feeder depends on the exact cap and must be confirmed by sample testing.
Bottle stability, cap placement, closure geometry, sensor spacing, tightening time and downstream accumulation all affect the sustainable result.
A platform may be configured for several closure families, but tooling, guides, head height and presentation method can differ. Each format must be included in the approved scope.
Confirm start/stop, bottle-present detection, low-cap condition where a feeder is used, queue control, emergency-stop interfaces and the recovery sequence after a stoppage.
A spindle route may be better for continuous higher-output lines with stable bottles and consistently pre-placed threaded caps.
Automatic-line evidence
The LU-XG16-class machine can only tighten a cap consistently after the closure has been presented correctly and the bottle has reached the capping point in a repeatable position. An automatic capper therefore has to be trialled as a sequence: cap supply, orientation, placement, bottle control, tightening, release and transfer to the next line stage.
The run video shows the relationship between conveyor transfer, bottle control and the capping station. It does not establish suitability for a different cap, bottle or output. The final system should be confirmed with representative production samples and an agreed test that includes normal stops, restart conditions and cap replenishment.
| Control point | Question to settle | Trial evidence |
|---|---|---|
| Cap feeder handover | Can the closure be oriented and released without nesting, scuffing, bridging or unstable presentation? | Normal production caps, low-level and refill conditions, and a record of every misorientation or stoppage. |
| Bottle indexing | Does the bottle arrive in the same position at steady running and after line stops? | Filled bottles across the intended size range, including the least stable format. |
| Tightening setup | Does the selected chuck or head grip the cap without marking it or distorting the bottle? | Approved settings, finished-pack checks and samples from start, middle and end of the run. |
| Line integration | Can the filler, capper, labeller and conveyors stop and restart without creating an uncontrolled queue? | Layout, conveyor direction and height, signal list and agreed accumulation strategy. |
Send caps, filled bottles, the required line sequence and the acceptance checks used by production or quality teams.
Automatic sequence
Automatic tightening depends on a clean transition from bottle detection and stopping to cap presentation, thread start, head contact, release and outfeed. Each interface should have an observable acceptance check.
| Sequence point | Control question | Trial evidence |
|---|---|---|
| Bottle arrival | Does the sensor detect the full format range and stop each bottle squarely? | Format extremes at normal conveyor condition. |
| Cap handover | Is the closure oriented, available and presented without damage or forced correction? | Feed/replenishment and recovery from a cap interruption. |
| Thread start | Does the cap locate before final tightening force develops? | Side-view observation, cap height and cross-thread inspection. |
| Head action | Does the tool contact the intended closure surface and release cleanly? | Tool identity, pack finish and repeatable cycle record. |
| Outfeed | Can the finished pack leave without back pressure, tip or recontact? | Connected-line or simulated accumulation test. |
Question-led guidance
Automatic operation must include bottle detection, cap availability, faults and controlled restart.
The intended control sequence should prevent an unsafe or meaningless capping cycle and identify which packs need inspection. Detection and response depend on the machine and cap-presentation scope. Define the required signals and fault behaviour in the line-interface schedule.
The line should return to a known state, clear or identify queued bottles and caps, restore spacing and require first-off inspection where needed. Restart behaviour must be tested with the connected feeder and conveyors rather than assumed from steady running.
The project may use operator inspection, sensors, measurement or downstream inspection depending on the accepted pack and line scope. Define the defect to detect, the reject method and what happens to uncertain packs. The closure-integrity guide helps define the acceptance evidence.
Some layouts can use operator-placed caps while retaining automatic bottle handling and tightening, but the sustainable output and safe operator position must be proved. If manual placement becomes the constraint, a feeder and controlled handover can be added to the project scope.
Send representative samples, target output and the current acceptance method so Lancing can review the correct capping route.
