Description

This disclosure relates to a method for manufacturing a laminate and an apparatus for manufacturing a laminate. Conventionally, a method and apparatus for manufacturing a reinforced fiber substrate are known in which sheet-like fiber material pieces are placed at an angle to the transport direction, and the side edges of adjacent fiber material pieces are welded together to produce a continuous sheet (for example, Japanese Patent Application Publication No. 2017-202658). Japanese Patent Publication No. 2017-202658 Figure 1 is a perspective view showing an overview of a laminate manufacturing apparatus according to an embodiment of this disclosure.Figure 2 is an exploded perspective view of the laminate.Figure 3 is an explanatory diagram of the arrangement of sheet materials in a laminate manufacturing method and laminate manufacturing apparatus according to an embodiment.Figure 4(A) is an explanatory diagram illustrating the adjustment of the sheet material arrangement pitch in the laminate manufacturing method and laminate manufacturing apparatus according to the embodiment. Figure 4(B) is an explanatory diagram illustrating the adjustment of the sheet material arrangement pitch in the laminate manufacturing method and laminate manufacturing apparatus according to the embodiment.Figure 5 is a flowchart showing the adjustment process for the arrangement pitch in the laminate manufacturing method and laminate manufacturing apparatus according to the embodiment.Figure 6(A) is an explanatory diagram illustrating the adjustment of the sheet material arrangement pitch in the laminate manufacturing method and laminate manufacturing apparatus according to the embodiment. Figure 6(B) is an explanatory diagram illustrating the adjustment of the sheet material arrangement pitch in the laminate manufacturing method and laminate manufacturing apparatus according to the embodiment.Figure 7 is an explanatory diagram of the welding of sheet material in the laminate manufacturing method and laminate manufacturing apparatus according to the embodiment.Figure 8(A) is an explanatory diagram of the welding of sheet material in the laminate manufacturing method and laminate manufacturing apparatus according to the embodiment. Figure 8(B) is an explanatory diagram of the welding of sheet material in the laminate manufacturing method and laminate manufacturing apparatus according to the embodiment. Figure 8(C) is an explanatory diagram of the welding of sheet material in the laminate manufacturing method and laminate manufacturing apparatus according to the embodiment.Figure 9 is a flowchart showing the welding control process in the laminate manufacturing method and laminate manufacturing apparatus according to the embodiment. A laminate manufacturing method according to one aspect of the present disclosure is a laminate manufacturing method for manufacturing a laminate by stacking a plurality of sheets, and includes a first arrangement step of arranging first sheet materials continuously in the direction of transport along a transport path for transporting sheets, and a second arrangement step of arranging second sheet materials continuously in the direction of transport above the first sheet materials arranged along the transport path. In the second arrangement step, the arrangement of the second sheet materials is performed at a position downstream of the arrangement position of the first sheet materials along the transport path. In the first and second arrangement steps, the arrangement pitch in the direction of transport of the first sheet materials or the second sheet materials can be adjusted by arranging the first sheet materials or the second sheet materials at an angle with respect to the direction of transport. According to the laminate manufacturing method according to one aspect of the present disclosure, when first sheet materials are arranged continuously along a transport path and second sheet materials are arranged downstream therefrom, the arrangement pitch in the direction of transport of the first sheet materials can be adjusted by arranging the first sheet materials at an angle with respect to the direction of transport. When arranging first sheet materials in a continuous line along a transport path, and then arranging second sheet materials downstream, the placement pitch of the second sheet materials in the transport direction can be adjusted by arranging them at an angle to the transport direction. For example, even if the sheet widths of the first and second sheet materials differ due to differences in size, the placement pitch of the first and second sheet materials in the transport direction can be matched by arranging either the first or second sheet material at an angle to the transport direction. This allows the first and second sheet materials to be placed at the same time. This enables the efficient manufacturing of laminates formed by stacking the first and second sheet materials.
