Document Type and Number:
Japanese Patent JP2014193525
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a molding material supply system which can prevent simply temperature variation of a molding material supplied to an extruder.SOLUTION: A molding system 1 includes a storage container 2, a hopper 3, an extruder 5, and a controller 6. A molding material supply system includes the storage container 2, the controller 6, carrying pipes 21, and a thermoelectric couple 22. A molding material 10 is carried from the storage container 2 through the carrying pipes 21 to the hopper 3 of the extruder 5. The carrying pipes 21 are arranged each on the central and peripheral side in the plane in the storage container 2. The controller 6 controls the carrying amount in each carrying pipe 21 by an automatic loader 4 on the basis of a temperature of the molding material 10 measured by the thermoelectric couple 22 arranged in the vicinity of the end part of the carrying pipes 21. The control of the carrying amounts makes nearly constant the average temperature of the molding material 10 carried into the hopper 3.
