Abstract

A molding system 10 for manufacturing a molded article Q by integrally molding a sheet-shaped insert member S and a molding material R, the molding system comprising: a sheet supply part 20 configured to supply the insert member S; a sheet heating part 30 configured to heat the insert member S; a molding apparatus 100 configured to form the molded article Q by integrally molding the insert member S and the molding material R; an ejector 200 including a delivery position 222 and configured to transfer the insert member S between the sheet heating part 30 and the molding apparatus 100 and to eject and transfer the molded article Q from the molding apparatus; and a transfer robot configured to transfer the insert member S or the molded article Q between the sheet supply part 20 and the ejector.

First claim

1 - 4 . (canceled)

5 . A method of manufacturing a molded article for manufacturing the molded article by integrally molding a sheet-shaped insert member and a molding material, the method of manufacturing the molded article comprising:
supplying the insert member from a sheet supply part arranged around a predetermined reference position; heating the insert member by a sheet heating part; forming the molded article by integrally molding the insert member and the molding material by a molding apparatus; transferring at least one of the insert member-and the molded article by an ejector including a delivery position arranged around the reference position; and transferring at least one of the insert member and the molded article between the sheet supply part and the ejector by a transfer robot arranged at the reference position.

6 . The method of manufacturing the molded article according to claim 5 , further comprising:
conveying the molded article by a conveyor apparatus arranged around the reference position; and transferring at least one of the insert member and the molded article between the sheet supply part, the ejector, and the conveyor apparatus by the transfer robot arranged at the reference position.

7 . The method of manufacturing the molded article according to claim 5 , further comprising:
cutting off a gate attached to the molded article by a gate cutting apparatus arranged around the reference position; and transferring at least one of the insert member and the molded article between the sheet supply part, the ejector, and the gate cutting apparatus by the transfer robot arranged at the reference position.

8 . The method of manufacturing the molded article according to claim 6 , further comprising:
cutting off a gate attached to the molded article by a gate cutting apparatus arranged around the reference position; and transferring at least one of the insert member and the molded article between the sheet supply part, the ejector, the gate cutting apparatus, and the conveyor apparatus by the transfer robot arranged at the reference position.
