Abstract

A convey device, which conveys an insert member into a die, includes a holding device configured to hold the insert member in an attitude in which a major surface of the insert member is in a substantially gravitational direction; a convey mechanism configured to convey the insert member to the die, while the insert member is being held in the attitude by the holding device; and a heating device configured to heat the insert member. The insert member can be heated by the heating device before the insert member is disposed in the die.

First claim

What is claimed is:

1. A method of manufacturing a molded article, comprising:
conveying, by a convey device, a thermoplastic prepreg to a heating device in an attitude in which a major surface of the thermoplastic prepreg is in a substantially gravitational direction, the convey device comprising:
a holding device configured to hold the thermoplastic prepreg in the attitude, the holding device comprising a chuck and a cooling device configured to cool the chuck, and
a convey mechanism configured to convey the thermoplastic prepreg while the thermoplastic prepreg is being held in the attitude by the holding device;

heating, by the heating device, the thermoplastic prepreg which has been conveyed in the attitude;
conveying, after the heating, the thermoplastic prepreg to a molding device to which a die is attached;
molding the thermoplastic prepreg by the molding device; and
controlling, by a controller, the cooling device to cool the chuck after the thermoplastic prepreg is conveyed to the molding device and before a second thermoplastic prepreg is conveyed to the heating device.

2. The method of manufacturing a molded article of claim 1 , wherein the thermoplastic prepreg is heated and made to stand by, before the thermoplastic prepreg is conveyed into the molding device.

3. The method of manufacturing a molded article of claim 1 , wherein the thermoplastic prepreg is heated immediately before the thermoplastic prepreg is conveyed into the molding device.
