Abstract

Si tratta di una centralina di smistamento automatica di granuli plastici per la produzione di oggetti in plastica di forme e colori diversi. La centralina collega i condotti provenienti dal silos delle varie plastiche con condotti di una o più presse di lavorazione. Tramite un motore elettrico e dei sensori di posizione il disco che regge il tubo di convogliamento alla pressa viene ruotato in modo da portare l'estremità del tubo in corrispondenza del tubo posto sul disco fisso, collegato al silos contenente i granuli di plastica prescelti. Durante la rotazione del disco una pompa provvede al lavaggio per depressione d'aria del tubo collegato al disco mobile in modo da rimuovere eventuali granuli o polvere di granuli eventualmente rimasti all'interno del tubo.It is an automatic sorting unit for plastic granules for the production of plastic objects of different shapes and colors. The control unit connects the pipes coming from the silos of the various plastics with pipes of one or more processing presses. By means of an electric motor and position sensors, the disk that holds the conveying tube to the press is rotated so as to bring the end of the tube to the tube located on the fixed disk, connected to the silos containing the selected plastic granules. During the rotation of the disc, a pump cleans the tube connected to the movable disc by vacuum in order to remove any granules or dust from the granules that may remain inside the tube.
