Constant quantity of adhesive for an economically efficient production
The innovative system is suitable to fill Robatech as well as other hotmelt equipment with granulate from a separate container. Hereby the level supervision of the melting tank takes care of the control. The granulate is fed through a suction tube placed in the container holding the adhesive granulate. The integrated venturi generates a negative pressure which attracts and feeds the granulate. The vibrator fitted to the suction tube supports the suction process. As soon as the set minimum fill level is reached, the level supervision transmits a signal to the control integrated in the equipment to release the filling cycle. The system monitors the stock of granulate and the filling process reliably. Constant processing temperatures are essential for continuous filling and represent a further advantage. In case of a nonconformity the process is interrupted and a corresponding message is released. Standstills due to an empty tank or overfilling belong to the past. Time and costs are saved in this manner and the production process is further optimized.
Higher operational and production safety
RobaFeed™ contributes decisively to an improved safety at work. Thanks to automatic filling of the closed tank the operators cannot come into contact with the hot adhesive and suffer injuries. Contaminants from the environment are prevented from reaching the adhesive. Vapours escaping from the fed granulate pass through an activated carbon filter and don't pollute the environment.
