Automatic bottle unscrambler
For manufacturers who need a steadier flow of empty bottles before filling, capping, labelling or coding equipment.
Specification advice
An automatic bottle unscrambler is normally specified when manual bottle loading is limiting the line, when operators are spending too much time correcting bottle orientation, or when downstream equipment needs more consistent infeed. It can reduce stoppages before fillers, cappers and labellers by presenting bottles in a more controlled stream.
The correct machine depends on bottle diameter, height, base stability, empty weight, plastic stiffness, production speed, conveyor height and the transfer point into the next machine. A practical specification should also consider changeovers, cleaning access, guarding and operator loading height.
Automatic unscrambling is commonly used for plastic bottles in cosmetics, household chemicals, food and drink, pharmaceutical-style containers, contract packing and other packaging lines where empty containers must arrive consistently at the first powered machine.

Questions
Typical output depends on bottle size and behaviour. The LU-LP150 route is listed at 30–60 bottles per minute for suitable small plastic bottles.
Yes, provided the transfer height, conveyor width, accumulation and controls are matched to the filling machine infeed.
LU-LP150 specification evidence
The LU-LP150 is the automatic route shown for small plastic bottles where manual arrangement is restricting the line. Published data should be checked against representative bottles and the complete outfeed into the next machine.
| Published parameter | Reference value | What still needs confirmation |
|---|---|---|
| Working speed | 30–60 bottles/min | Sustainable output with the actual bottle, loading pattern, line stops and downstream demand. |
| Suitable bottle range | Diameter 20–100 mm; height 20–150 mm | Base stability, wall stiffness, neck/shoulder geometry and whether all planned formats share a practical setup. |
| Power and voltage | 1000 W; 220V 50Hz | Final electrical connection, isolation and site responsibilities. |
| Machine size and weight | About 1100 × 1616 × 1163 mm; about 260 kg | Loading access, guarding clearance, maintenance access, outfeed direction and connection to the line. |

Bottle trial and changeover
Automatic bottle arrangement is most useful when the real container can be presented repeatedly without tipping, bridging or excessive contact. The trial set should include the smallest, largest and least stable bottles in the proposed range. Inspect visible surfaces after the run for scuffing or marking and confirm whether any guide adjustment or dedicated change part is required.
Ask for a continuous orientation video that shows bulk loading, bottle movement, outfeed presentation and the transfer into the downstream conveyor. Include planned stops, restart and a controlled recovery test so the operator procedure is understood before site commissioning.

Automatic-route questions
No. It is published reference data. The actual sustainable result depends on bottle geometry, loading, changeovers, downstream demand and the complete line setup.
Include the smallest, largest and least stable bottles, plus any format with a different base, shoulder, wall stiffness or presentation requirement.
Inspect representative clean bottles before and after the trial under suitable lighting, especially at contact points, guide rails and transfers.
Record detection, stopping, safe access, removal of the affected bottle, restart and whether the same condition immediately repeats.
A rotary route may be the simpler starting point when stable bottles only need compact accumulation and controlled delivery rather than automatic arrangement.
Provide the conveyor height and direction, downstream machine, sustained target output, available footprint, access restrictions and control/interface requirements.
Orientation evidence
A useful demonstration should show how bottles enter the machine, how they are arranged, how rejected or unstable bottles behave, and how the outfeed transfers into the next conveyor. Edited close-ups of a successful outfeed do not show whether the complete route is stable.
| Video view | What should remain visible | Question answered |
|---|---|---|
| Loading and settling | The representative loading method, bottle crowding and the point where bottles enter the arrangement process. | Does the normal loading method create bridging, excessive pressure or manual assistance? |
| Arrangement route | Bottle movement through the machine, including any recirculation or bottle that does not present correctly on the first attempt. | Can the bottle geometry be handled consistently rather than only in a selected best-case sequence? |
| Outfeed presentation | The bottle attitude, spacing, guide contact and the complete handover into the downstream conveyor. | Does the delivered bottle condition suit the filler, capper or labeller infeed? |
| Planned stop and restart | Downstream stop, bottle build-up, machine response, restart and the first bottles after recovery. | Does the route restart without uncontrolled pressure, surging or repeated manual correction? |
| Changeover extremes | The smallest, largest and least stable approved bottles, with settings or dedicated parts identified. | Is the claimed bottle family supported by repeatable settings and evidence? |
If the project only needs compact accumulation and bottles remain stable without controlled orientation, compare the rotary bottle unscrambler route. Use the sample-testing guide for stability, surface inspection and recovery evidence.
Use production-condition bottles for the evidence pack wherever possible. Decoration, mould variation, wall stiffness and bottle storage can change the way an empty container settles and presents. Keep the camera position, loading method and settings consistent between formats so the smallest, largest and least stable bottles can be compared fairly instead of relying on separate edited clips.
Orientation evidence
A short outfeed clip is not enough to confirm automatic unscrambling. The useful evidence shows how the difficult bottle enters the machine, is arranged, reaches the correct presentation and recovers after a normal stop.
Record bottle dimensions, material, empty weight and the setting or change parts used for the trial.
Show the real loading method and enough bottles to observe bridging, hesitation or unstable behaviour.
Keep the bottle path visible through arrangement, orientation, rejection or recirculation and final discharge.
Include a normal downstream stop, restart and return to stable flow without editing out the transition.
| Video view | What it should establish | What to record separately |
|---|---|---|
| Bulk-load and internal flow | Whether the sample settles, separates and enters the arrangement route consistently. | Loading quantity, operator method and any manual correction. |
| Orientation zone | Whether the agreed bottle presentation is achieved for the full sample set. | Mis-orientation, recirculation, reject or intervention events. |
| Outfeed and transfer | Whether bottles leave upright and stable at the agreed conveyor height and direction. | Guide settings, transfer gap and downstream conveyor speed. |
| Stop and restart | Whether bottle accumulation and restart remain controlled under normal line demand. | Cause of stop, clearance action and time to stable flow. |
Use the full orientation video trial guide and retain the recording with the changeover settings for each approved bottle family.
Automatic-line questions
Automatic bottle presentation must be considered as part of the complete line response, not as an isolated running demonstration.
The automatic bottle unscrambler should respond to the agreed downstream backup condition without continuing to create an unstable or damaging queue. The exact response may be a controlled stop, reduced feed or another sequence defined by the supplied controls. When the downstream condition clears, the restart should recover flow without releasing an uncontrolled surge of bottles.
The required signal, delay and restart sequence should appear in the project I/O schedule. Use the controls and signals guide to agree the interface.
Run the agreed bottle at normal operating conditions, deliberately create the defined downstream backup, hold the condition long enough to observe the bottle queue, then clear it and record the recovery. Repeat the sequence several times and after the most important changeover. The test should confirm stable bottles, correct signals, no unsafe intervention and a predictable return to flow.
Include this sequence in both the supplier-site and installed-line checks described in the FAT and SAT guide.
Changeover becomes more involved when bottle-specific guides, pockets, chutes, sensor positions, heights or timing settings must change together. Large differences in bottle diameter, height, base shape or orientation requirement can create more work than a simple guide adjustment. The quotation should distinguish adjustable settings from dedicated change parts and state how the final setup is recorded.
Use the current changeover evidence guide to define the settings sheet, parts list and repeatability check.
The loading method should let operators replenish bottles safely without suddenly overfilling the feed area or starving the line. Agree the normal batch quantity, low-level indication, access position and maximum loading condition. Operator reach, container handling and the path used to bring bottles to the machine should be reviewed during the layout survey, not after installation.
The site-survey guide lists the access, loading and service information needed to confirm the arrangement.
Automatic-route evidence
An automatic route should be supported by representative bottles and a line-ready interface brief rather than a headline speed alone.
Include the smallest, largest, lightest and least stable empty bottles expected in production.
Capture loading, arrangement, discharge, stop, restart and recovery for the agreed bottle family.
Agree downstream demand, backup, fault, reset and retained-conveyor responsibility before release.
Record adjustments, change parts and settings needed to repeat the approved result.
Week 2 buyer questions
Lightweight bottles can behave differently as material, environment and contact history change. Keep uncertain performance trial-dependent.
Static charge can make lightweight plastic bottles cling to each other, guides, guarding or contact surfaces instead of separating predictably. Symptoms may include intermittent doubles, bottles following an unexpected path, inconsistent release and behaviour that changes with material, humidity or handling. The machine route should be tested with the real empty bottles under representative conditions. Static should be treated as a variable to observe, not as a performance figure to assume.
Air movement from nearby equipment, extraction, open doors or deliberate air assistance can disturb very light bottles before they are mechanically controlled. A bottle may rotate, lean or change position between the arranging section and outfeed even when the machine is correctly set. Trials should note the surrounding airflow, repeat the same stop/restart conditions and separate airflow effects from faults caused by guides, transfers or excessive speed.
Test the formats that challenge different parts of the route: the lightest bottle for static and airflow, the tallest or narrowest-base bottle for stability, the widest or shortest bottle for guides and spacing, the softest bottle for pressure, and any format with a difficult shoulder or orientation requirement. A family may therefore need several governing samples rather than one nominal bottle representing the whole range.
Record an unbroken view that shows bottle loading, disorder in the bulk section, the arranging or orienting action, single-file outfeed, transfer to the downstream conveyor and recovery after a planned stop. Include enough bottles to show repeatability rather than one successful cycle. Identify the bottle format, machine settings and trial condition in the record. Avoid tight edits that hide a blockage, manual correction or unsuccessful restart.
Inspect bottles for fresh scuffs, dents, deformation, contamination and marks at repeated contact points. Check that guides, discharge rails, sensors and change parts remain secure and that no bottle debris has collected in the path. Review rejected or manually corrected bottles separately from successful output. The trial record should connect any observed condition to the bottle format, machine setting and point in the route where it first appeared.
Loading and access
The arrangement mechanism cannot be assessed separately from bottle replenishment, operator access and the way the line responds to stops.
Define the source of empty bottles, the normal amount added at one time, how often replenishment is expected and the point at which the machine should request more bottles. The agreed method should be reproduced during the trial because bottle crowding, separation and static can change when the loading pattern changes.
Check the normal bottle-loading position, guard doors, electrical controls, inspection points, change-part access, cleaning access, discharge transfer and the space needed to clear a blockage safely. Also confirm that nearby conveyors or machines do not obstruct a routine task. These checks belong in the site survey and installed-layout review.
A clear view helps the operator recognise bridging, unusual accumulation, bottle damage and poor separation before the condition reaches the discharge. It also supports consistent replenishment and quicker fault reporting. Visibility should be considered with guarding and access; it should not depend on bypassing a guard or reaching into the machine.
Record the approved machine speed or control range, guide positions, relevant sensors, bottle-level settings, dedicated change parts, discharge settings and first-bottle verification checks. Include the bottle ID and sample evidence used to accept the setup so that a later changeover can return to the same proven condition.
