Electronic modification of existing hopper feeders, Nuova Cosmatex / Monteleone Group

The modification consists in the elimination of the existing weighing pan and improving of the weighing system with the supply of: • electronic weighing pan with load-cell, detached from the hopper itself (to avoid being influenced by hopper vibrations), very sensible, with pneumatic opening motion; • Possible installation of a pneumatically driven lappet for stopping the flow of material inside the weighing pan once the drop weight is reached; • electrical / electronic control panel with no.3 inverters, with drop weights and false-drop weights information, average, minimum and maximum weight value, CV value, etc. These data can be printed. The weighing system is measured by a computer type DTS equipped with a new software with self-learning cycles that automatically searches for the optimisation between the weighing and speed times of the loading lattices of the hopper feeder. In that way the weighing phase, besides being very precise, is greatly simplified and avoids human mistakes brought by manual settings and adjustments of the machine. • To avoid forced stops, the hopper feeder can even work with a mechanical/electrical driving system. • Possible new motorization of the hopper feeder or part of it, if required.
