  • Publication number: 20240123470
    Abstract: A ply sorting device is disclosed, comprising a picker and a buffer. The picker is arranged to pick planar plies of cut fiber material and move them to the buffer. The buffer comprises a plurality of substantially planar supports each arranged to receive plies from the picker and to support the plies in planar orientation. The planar supports are movably arranged relative to each other to receive the plies. In addition, a method of sorting plies of differing geometry is disclosed. Planar plies of cut fiber material are picked and moved to supports of a buffer where plies are received in a planar orientation, and supports are moved relative to each other to receive the plies.

  • Patent number: 11883855
    Abstract: A ply sorting device is disclosed, comprising a picker and a buffer. The picker is arranged to pick planar plies of cut fiber material and move them to the buffer. The buffer comprises a plurality of substantially planar supports each arranged to receive phes from the picker and to support the plies in planar orientation. The planar supports are movably arranged relative to each other to receive the plies. In addition, a method of sorting plies of differing geometry is disclosed. Planar plies of cut fiber material are picked and moved to supports of a buffer where plies are received in a planar orientation, and supports are moved relative to each other to receive the plies.

  • Publication number: 20220258437
    Abstract: A preforming system for automated sequential laying of plies, in particular fiber reinforced plies, at a desired location with a preselected attitude to preform a composite structure, comprising at least one buffer provided with two or more carriers, a controller, a placement robot provided with a ply manipulating part, and a substrate, wherein each carrier is arranged to carry at least one presorted ply, wherein the controller keeps track of a position, type and sequential order of the at least one presorted ply per carrier, and wherein the controller further controls the placement robot to manipulate and transport at least one ply by means of the ply manipulating part from a selected carrier of the two or more carriers to the substrate and to place the at least one ply at the desired location with the preselected attitude.
