Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to FRP (fibre reinforced).
The present invention relates to an automatic laminating device for roving material, which is one of the intermediate materials for parts made of composite material known as plastic).

2. Description of the Related Art FRP having glass fiber or carbon fiber as a reinforcing fiber and polyester or epoxy resin as a binder has been widely used as a material for parts requiring high strength and light weight. In particular, when manufacturing parts such as rotor hubs of helicopters that are complicated in shape and require high strength by FRP, dozens of long fibers are bundled in reinforcing fibers to form a filamentous roving material that is pre-impregnated with resin (prepreg). A method is suitable in which a die (jig) made in conformity with the shape of (1) is laminated by utilizing its adhesiveness and then cured.

By the way, conventionally, as for the method of laminating the roving material, it has been usual that a skilled worker arranges and lays them one by one on a mold by hand according to the drawings. However, this method has problems that it takes a very long time to stack and that the quality of the product differs from that of the product due to the variation of the stacked state.

For the purpose of improving these problems, for example, JP-A-63-3
Japanese Patent No. 5341 proposes an apparatus for automatically laminating prepreg-reinforced fibers on a mold. The reinforcing fiber used in this device is a tape-shaped one in which a large number of reinforcing fibers are arranged in a strip shape on a backing paper having a predetermined width, for example, about 76 mm, in order to retain the shape and impregnated with resin. The automatic stacking device is a stacking head assembly mounted so as to be movable by a gantry in a traveling direction (X axis), a direction orthogonal thereto (Y axis) and a vertical direction (Z axis) and rotatable about the Z axis. Consists of

The laminating head assembly has a material supply reel for holding the above-mentioned laminated material in a roll shape, the laminated material unwound from this reel is pressed against the mold surface by the pressing member, and the backing paper is peeled off, It is wound up on a backing paper winding reel provided in the head assembly. The tension when the material is attached to the backing paper is held by the backing paper, and the tension at the time of stacking is generated by the material supply reel and the backing paper winding reel. In cutting the material, the backing paper is not cut, only the prepressed fibers are cut, and the cutting direction can be cut in any direction with respect to the longitudinal direction. In many cases, the cutting directions of the stacking start point and the end point do not coincide with each other, and scrap is generated after cutting. Therefore, the processing is required.

In the above-mentioned prior art, since the laminated material is attached to the backing paper having a certain width as described above, it is impossible to laminate the developed surface into an S-shape. In addition, since the head assembly has a reel for material supply and a reel for winding backing paper, which is large and complicated, it cannot be applied to the production of small and complicated parts such as a rotor hub of a pericopter. There is a structure in which the head can be swung about the center line of the tape so that the head can be stacked on the slope, but in that case, the number of parts such as a driving device and a sensor for that purpose increases, and the weight also increases.
