AROL expelling systems are designed to detect and remove non-compliant caps (inverted, missing foil/liner, defective) either automatically or manually along the feeding channel.
They are key components for maintaining operational continuity, reducing jams, and preserving overall line efficiency.
MRS – Manual Rejecting System
Manual expelling system for inverted caps. Suitable for speeds up to 25 000 cph.
Main features:
- Manual removal of overturned caps
- Dedicated sensor detects incorrect cap position
- To be installed away from the pick & place inlet curve
AED – Automatic Expeller Device
Automatic system that ejects inverted caps using a pneumatic actuator.
Main features:
- Automatic detection of overturned caps
- Pneumatic cylinder for expulsion
- Compliant caps continue to the pick & place
D-AED – Dual Expeller Device
A solution dedicated to caps with long pourers, which are not compatible with the standard single starwheel.
Main features:
- Combination of a mechanically synchronized infeed starwheel with one or two inverted-cap detection starwheels
- Suitable for complex geometries
LS-AED – Linear Sensor Automatic Expeller Device
Ideal for caps with magnetic foil. Uses an inductive sensor to identify inverted or foil-less caps.
Main features:
- High detection accuracy
- Ejection by momentary stop and targeted sorting
- Maintains a continuous flow between sorter and capper
LC-AED – Linear Camera Automatic Expeller Device
Suitable for caps with non-magnetic foil, it uses a camera to detect anomalies.
Main features:
- High detection accuracy
- Ejection by momentary stop and targeted sorting
- Maintains a continuous flow between sorter and capper
- Integrated machine vision system
Thanks to the implementation of these systems, production lines maintain high efficiency, avoid blockages, and improve the overall quality of the capping process.
