The Applications
1. Transparent Bottle Detection in Beverage Filling Lines
In beverage filling plants, detecting transparent PET or glass bottles is often a challenge due to light reflections and variable surfaces. The SICK GRL18S-F1336 solves this using its dual-lens optical system and polarization filter, ensuring steady detection even on reflective containers. With its quick 500 µs response, the sensor keeps pace with fast conveyor movement, preventing underfill or overfill errors. Its IP67 housing offers durability during washdowns, making it ideal for humid bottling and labeling zones.
2. Counting and Sorting on High-Speed Conveyor Systems
Packaging lines demand accurate item counting and reliable sorting, even at high speeds. The GRL18S-F1336 handles this efficiently, offering consistent detection of boxes, pouches, or plastic trays regardless of surface reflectivity. The visible red PinPoint LED ensures quick optical alignment, while the high switching frequency keeps pace with rapid automation cycles. It helps reduce counting errors, supports synchronized labeling, and maintains continuous production flow in modern packaging facilities.
3. Position Verification in Robotic Palletizing Systems
During automated palletizing, each box must be accurately positioned before stacking. The GRL18S-F1336 provides dependable verification through its axial optical alignment and long detection range of up to 7.2 meters. Its compact M18 cylindrical body integrates neatly within robotic arms or frame mounts, enabling real-time feedback to robotic controllers. This prevents stacking misalignment, reduces collision risk, and ensures smooth operation in automated material handling environments.
4. Vehicle and AGV Detection at Warehouse Gates
In automated warehouses, forklifts and AGVs must be precisely detected for safe gate operation and traffic control. The GRL18S-F1336 delivers reliable detection of reflective metal surfaces and safety reflectors under varying light conditions. With a robust ABS housing and wide temperature tolerance, it performs consistently in dusty or semi-outdoor loading areas. This improves gate response timing, enhances safety, and optimizes vehicle flow efficiency throughout logistics operations.
