The concept behind it is simple: RF DSENS-NET wireless sensors are installed at the entrance and/or exit of the monorail lanes where the dollies are "parked". They register the movements of full or empty dollies in a monorail lane and can trigger a replenishment order in the user's IT system (ERP, WMS, etc.) via radio, for example. Nexy thus closes a gap in the information flow and - thanks also to real-time transmission - creates the conditions for greater supply reliability in production. At the same time, the replenishment time for the material is reduced - leading to a significant increase in efficiency in the replenishment process.

Robust and reliable

The sensors for the monorail tracks are a customized development. On the one hand, they have to be robust, but on the other hand they have to be able to detect the removal or feeding of the floor rollers from the respective track very accurately. This task is performed by sensors that are well protected in a robust housing. The batteries for the power supply are also integrated, with a battery life of more than five years.

Removal and feeding decided automatically

As the sensor detects the direction of travel of the dollies, it can automatically differentiate between the removal and supply of the trolleys. The sensor bridge software can be used to configure whether the sensor should detect one or two axes before the counting process is transmitted by radio. The radio ID of the sensor enables the sensor to be clearly assigned in the system.

These second-generation dolly sensors, which are as robust as they are precise, enable reliable radio-based dolly monitoring in real time. This is an important addition to the Nexy platform for automated replenishment. With the Nexy radio network, Steute has developed a complete radio-based system for recording and controlling material stocks in intralogistics. The associated range of wireless sensors is being continuously expanded.
