SICK has launched its deTec4 Smart Box Detection access protection system, which allows secondary packaging machines in the end-of-line area, top and side loaders, or sorter and ejector modules to be operated in a safe and user-friendly manner.
With the help of a reliable pattern detection logic, Smart Box Detection can safely differentiate rectangular objects, such as boxes, from people and body parts in the inlet and outlet zones of packaging machines or logistics conveying systems, SICK said. This lets boxes be transported continuously without any stops into and out of fenced-in machines. Because the safety solution requires no external process signals or muting sensors, it allows a cost-effective, flexible, compact and maintenance-optimized machine design, while also ensuring maximum operating safety, the company said.
The system can detect objects with a rectangular contour and measuring 13 cm or greater in height as they enter the constantly active deTec4 protective field. An evaluation of the interrupted light beam ensures a safe differentiation between humans and materials, as people that move over a conveying line or reach into a machine have a fundamentally different geometry, creating significantly different beam interruption patterns. SICK said this reliably avoids erroneous safety stops of the conveying equipment.
The system can be integrated directly into the deTec4 safety light curtain as supplementary functionality, and requires no additional signals from automation systems or muting sensors during operation. It also requires no additional programming, mounting or wiring, and can be configured to suit the requirements of several applications, SICK said.
Maintenance is also simplified – if objects of different heights and lengths need to be detected in operation, it is not necessary to teach them in or adjust the configuration of the safety solution, providing a maximum level of versatility and flexibility, while ensuring the highest possible productivity of the system.
