Abstract

See full text

A material feed system provided with a plurality of injection molding machines. A filling station is provided and has a resin tank in which resin material is stored, a container to which the resin material is fed from the resin tank, and a coupling device for coupling the resin tank and the container on demand. A carrier having a clamping mechanism runs along a track which is laid so as to pass over the injection molding machines and the filling station. The coupling device is controlled by a control unit. The control unit also controls the movement of the carrier to thereby transport the container by the use of the clamping mechanism and to feed the resin material from the container to the injection molding machines.
