Loading scale VW-500
The VW-500 loading scale has been developed for modern silo logistics. This system is indispensable due to the very high levels of accuracy it achieves. For standard products such as granulate, sugar, etc., these are +/- 20 kg for a loading quantity of 25,000 kg. Overloading of the vehicle is therefore impossible. It is also possible to carry out precise loading of individual chambers of the vehicle.
The system is calibrated according to MID 2014/32/EU and saves the necessary second weighing of the vehicle. Order management can be automated by connecting to customer-side databases or software systems such as SAP. All weighing data is stored in an alibi memory for at least 3 months. Depending on customer requirements, requirements or performance, the system can be integrated into existing silo systems.
Control
The scale has a self-sufficient control system with integrated, calibratable weighing electronics and a Siemens S7 PLC. The scale can be operated entirely via the touch panel. The connection to the silo control system is made via plug contacts with the signals “Silo open” and the feedback signals, as well as via the corresponding approvals.
Silo connection
The silo connection can also be done in a wide variety of ways. Here there is the possibility of a pressure device that presses firmly to the silo outlet. Alternatively, there is also aPipe system that slides around the silo outlet pipe without a fixed connection. A positioning accuracy of at least +/-50 mm is guaranteed.
Weighing system
In such systems, the weighing vessel is usually designed with a nominal filling capacity of 500 kg. The vessel outlet must be sufficiently large to allow rapid emptying. All weights are recorded in a manner that allows calibration. The weighing container is connected to three high-precision ball supports.
Discharging hopper
The discharging hopper ensures that the product is quickly picked up after the weighing process and dispensed in precise doses. While the scales are already dosing the next fill, the secondary container continuously unloads into the truck. This results in a uniform material flow with optimal adjustment. An integrated level detector reliably monitors the container level.
Positioning aid
Manual positioning aid for easy positioning of the scales under the silo
Terminal at the loading point
Touch panels can be installed on the loading telescope as an option. These enable structure-based operation by the loader in almost all languages.
Identification systems
Contactless identification systems allow lorries/drivers to be assigned to a specific order, thereby ruling out incorrect or mistaken loading.
