Abstract
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.
Claims14
An injection molding system comprising:
- a plurality of injection molding machines;
- a resin storage unit for storing resin which is to be injected into said injection molding machines;
- a container that is selectively and mechanically detachable from said resin storage unit for containing said resin fed from said resin storage unit, said container being positioned adjacent to said resin storage unit when the container is located at a rest zone in which the container is at rest;
- a transportation track extending between said rest zone and said plurality of injection molding machines;
- a carrier associated with said transportation track for holding said container and for conveying said container along said transportation track between said rest zone and said plurality of injection molding machines;
- and
- control means electrically coupled to said container and said carrier for controlling said container and said carrier to selectively detach said container from said resin storage unit and to convey said carrier along said transportation track with said container held by said carrier.
An injection molding system comprising:
- a plurality of injection molding machines;
- a plurality of resin tanks for storing a plurality of resins which are to be injected into said injection molding machines;
- a plurality of containers that are selectively and mechanically detachable from said resin tanks for containing said resins fed from said resin tanks, said containers being positioned adjacent to said resin tanks when the containers are located at rest positions in which the containers are at rest;
- a transportation track extending between said rest positions and said plurality of the injection molding machines;
- a carrier associated with said transportation track for selectively holding each of said containers and for selectively conveying each of said containers along said transportation track between said rest positions and said plurality of injection molding machines;
- and
- control means electrically coupled to said plurality of containers and said carrier for controlling said containers and said carrier to selectively detach said containers from said resin tanks and to convey said carrier along said transportation track with one of said containers held by said carrier.
