Prepreg lamination head and prepreg automatic lamination device equipped with same
A prepreg lamination head and a prepreg automatic lamination apparatus with the same is provided. By using them, the curling-up of the cut terminal portion of the prepreg sheet can be prevented. The prepreg lamination head includes: a first roller, a second roller, and a forward-placed paper liner peeling device. The forward-placed paper liner peeling device includes a third roller, which is provided between and above the first and second rollers. The paper liner attached on the first side of the prepreg sheet is peeled off right after passing the first roller. The peeled paper liner is hanged over the third roller between the first and second rollers. The third roller guides the peeled paper liner to the second roller. The prepreg sheet is pressed on the laminated body with the second roller through the paper liner.
1. A prepreg lamination head for laminating a plurality of prepreg sheets made of fiber sheet impregnated with resin to form a prepreg laminated body, wherein a paper liner being stuck over a first side of the prepreg sheet, and a direction of a fiber in the prepreg sheets being directed to a first direction along with a length direction of the laminated body, the prepreg lamination head comprising:
a first roller, which is provided in a front side of a work being laminated and guides the prepreg sheet to the first direction for the prepreg sheet to be laminated on the work being laminated;
a second roller, which is provided in a rear side of the work being laminated and guides the prepreg sheet, which has passed the first roller, for the prepreg sheet to be pressed from the first side of the prepreg sheet and for the paper liner to be peeled off from the first side of the prepreg sheet; and
a forward-placed paper liner peeling device, which peels off the paper liner from the first side of the prepreg sheet between the first and second rollers, and guides the prepreg sheet for the peeled paper liner to be pressed and stuck back to the first side of the prepreg sheet with the second roller.
2. The prepreg lamination head according to claim 1 ,
wherein the forward-placed paper liner peeling device comprises:
a third roller, which is provided above the first and second rollers and on which the liner paper between the first and second rollers is hanged over.
3. The prepreg lamination head according to claim 2 ,
wherein the forward-placed paper liner peeling device, which includes the third roller, comprises:
a scraper, which peels off the paper liner from the first side of the prepreg sheet having passed the first roller and guide the peeled paper liner to the third roller, the scraper being provided between the first and third rollers in the first direction, and below the third roller.
4. A prepreg automatic lamination apparatus for producing a prepreg laminated body by laminating a plurality of prepreg sheets formed by impregnation of a fiber sheet in resin comprising:
the prepreg lamination head according to claim 1 ; and
a lamination table, which allows a forward and a backward movement of the work being laminated relative to the prepreg lamination head in the first direction,
wherein the lamination table comprises:
a plurality of suction holes opening at a top surface of the lamination table on which the work to be laminated is placed; and
the work to be laminated is maintained in a stuck-state by sucking air from the suction holes.
5. A prepreg automatic lamination apparatus for producing a prepreg laminated body by laminating a plurality of prepreg sheets formed by impregnation of a fiber sheet in resin comprising:
the prepreg lamination head according to claim 2 ; and
a lamination table, which allows a forward and a backward movement of the work being laminated relative to the prepreg lamination head in the first direction,
wherein the lamination table comprises:
a plurality of suction holes opening at a top surface of the lamination table on which the work to be laminated is placed; and
the work to be laminated is maintained in a stuck-state by sucking air from the suction holes.
6. A prepreg automatic lamination apparatus for producing a prepreg laminated body by laminating a plurality of prepreg sheets formed by impregnation of a fiber sheet in resin comprising:
the prepreg lamination head according to claim 3 ; and
a lamination table, which allows a forward and a backward movement of the work being laminated relative to the prepreg lamination head in the first direction,
wherein the lamination table comprises:
a plurality of suction holes opening at a top surface of the lamination table on which the work to be laminated is placed; and
the work to be laminated is maintained in a stuck-state by sucking air from the suction holes.
