Automatic Bottle Unscrambler for PET Filling Lines
An automatic bottle unscrambler machine receives bulk, randomly oriented empty bottles and delivers them in sequence to a downstream air conveyor. It is intended for suitable PET beverage bottles ahead of a filling line. Bottle dimensions, shape and neck finish must be checked against the machine's handling parts and conveyor interface.

Bottle Unscrambler Features and Controls
- Bottle-block detection can trigger an alarm, while a rejection mechanism removes improperly oriented bottles.
- A neck-support air conveyor helps maintain bottle orientation during transfer.
- PLC controls and a digital speed display support line operation.
- Photoelectric sensors can coordinate the unscrambler with the air conveyor and bottle elevator.
- Low-bottle detection can signal the elevator to supply more bottles automatically.
- Lubrication access for the gear, bearing and cam supports routine maintenance.
Bottle Unscrambler Structure and Working Principle
The machine has a cylindrical housing on adjustable feet, a rotating bottle-handling section, a fixed distribution tower and a lifting mechanism. Bottles enter from the elevator, move toward the tower edge and are guided into lifting positions. A cam-driven mechanism orients and transfers them to the outlet, where a star wheel delivers bottles to the air conveyor. The final layout and bottle-handling parts depend on the selected bottle format.

PET Bottle Unscrambler Applications
This machine supports automatic handling of suitable empty bottles before beverage and food filling. Other bottle shapes, including selected round or square containers, require a format review; suitability for non-PET materials should be confirmed rather than assumed.
