摘要： Systems and methods are provided for placing preforms onto a mandrel. One illustrative method includes moving a mandrel in a process direction relative to a station that comprises multiple pick-and-place (PNP) machines, identifying a tray that stores a preform comprising an unhardened fiber-reinforced material, placing the strong back at the preform via at least one of the PNP machines, applying a vacuum to hold the preform in contact with the strong back, transporting the preform to a mandrel via the PNP machines, and placing the preform onto the mandrel.

摘要： Systems and methods are provided for assembling a structure (12) from preforms (150) including discrete preforms (154) and one or more large preform (156), each preform (150) comprising unhardened fiber-reinforced material (152), the method (400) comprising:
moving (402) a mandrel (140) in a process direction (14) relative to a placement station (100) that comprises multiple pick-and-place (PNP) machines (130);
identifying (422) a tray (190) that stores the one or more large preforms (156) and the discrete preforms (154), the discrete preforms (154) arranged for placement at locations (781) in which a frame (780) is to be installed relative to the large preforms (156);
placing (428) a strong back (180) at the tray (190) via at least one of the PNP machines (130); applying (406) vacuum pressure (160) to hold (444) the one or more large preforms (156) and the discrete preforms (154) in contact with the strong back (180);
transporting (460) the one or more large preforms (156) and the discrete preforms (154) to the mandrel (140) via the at least one PNP machine (130) while maintaining an arrangement of the one or more large preforms (156) and the discrete preforms (154); and
placing (472) the one or more large preforms (156) and the discrete preforms (154) onto the mandrel (140), preferably wherein the discrete preforms (154) are frame filler preforms (158) and the large preform (156) is a stringer preform (159).-

摘要： Systems and methods are provided for assembling a structure (12) from objects (18) including discrete objects (20) and a large object (22) that is bigger than the discrete objects (20), the method (300) comprising:
operating (314) a first subset (126) of pick-and-place (PNP) machines (130) at a placement station (100) independently in an asynchronous phase (354) to place the discrete objects (20) onto a mandrel (140);
while operating (314) the first subset (126) in the asynchronous phase (354), for each of the PNP machines (130a) in the first subset (126): providing (306) new instructions (124) from a program (122) in response to detecting that prior instructions (124) from the program (122) have been completed by the PNP machine (130a), regardless of progress of other PNP machines (130) in the first subset (126);
operating (326) a second subset (128) of PNP machines (130) in tandem in a synchronous phase (356) to place the large object (22) onto the mandrel (140) simultaneously with the operating (314) of the first subset (126) of PNP machines (130), wherein the large object (22) spans multiple PNP machines (130b, 130c); and
while operating (326) the second subset (128) in the synchronous phase (356), providing (318) new instructions (124) from the program (122) to each of the PNP machines (130b, 130c) in the second subset (128) in response to detecting that all of the PNP machines (130b, 130c) in the second subset (128) have completed a prior instruction (124) from the program (122).
