Compactor and prepreg sheet automatic lamination device

A prepreg sheet automatic lamination device for laminating a plurality of semi-cured prepreg sheets, the prepreg sheet automatic lamination device comprising:

• a compactor group including a plurality of compactors that are arranged, each of the compactors being configured to press a laminated sheet including a release sheet and a semi-cured prepreg sheet attached to a first surface of the release sheet onto a top surface of a laminate base formed of at least one semi-cured prepreg sheet, from a second surface side of the release sheet of the laminated sheet;
• a stage on which the laminate base is placed horizontally;
• a laminated sheet supply roller configured to horizontally supply the laminated sheet onto the top surface of the laminate base;
• and
• a release sheet recovery roller configured to recover the release sheet peeled off from the semi-cured prepreg sheet pressed, by the compactor group, onto the top surface of the laminate base,
• each compactor including:
• a pair of first rollers disposed separated from each other, each of the first rollers having a first roller surface that presses the laminated sheet from the second surface side of the release sheet;
• and
• a second roller having a second roller surface that presses the laminated sheet from the second surface side of the release sheet, the second roller being disposed such that the second roller surface faces a gap provided between the pair of first rollers,
• the compactor group being movable horizontally along the top surface of the laminate base independently from the laminated sheet supply roller and the release sheet recovery roller, wherein
• the plurality of compactors forming the compactor group are arranged such that the pair of first rollers and the second roller from each compactor are alternately disposed in a direction intersecting a feed direction of the laminated sheet, and
• the first roller surfaces that are constituents of one of the compactors are disposed so as to face the first roller surfaces of other compactors disposed adjacent to the one of the compactors.
