Definitions
- the present application relates to fiber placement machines and, more particularly, to a fiber placement head that threads composite tape into the head from a spool.
- Fiber placement machines are used to create composite workpieces.
- Composite tape or material in the form of fibrous material impregnated with resin, is applied by the machines to a mold or mandrel at precise locations and lengths to collectively form a composite workpiece.
- the fiber placement machines move a fiber placement head over the mold to precisely apply composite tape in the ultimate shape of the composite workpiece.
- the length of the segment(s) is defined by a cutting action that separates the segments from a supply of composite tape on a spool.
- Some workpieces involve the application of differently sized composite tape that can be stored on or carried by other spools and/or fiber placement heads.
- a robotic arm can release an existing fiber placement head threaded with one type or size of composite tape and select a new, different fiber placement head threaded with a different type or size of composite tape.
- Each fiber placement head can be pre-threaded with composite tape by a person, such as a machine operator, who manually threads an end of the composite tape from a spool to the fiber placement head.
- maintaining a plurality of fiber placement heads each with its own manually threaded composite tape can increase cost and complexity.
- a fiber placement head assembly for applying a plurality of composite tape segments on a mold that includes a fiber placement head configured to receive composite tape from a composite tape source and apply the composite tape to the mold.
- the assembly also includes one or more airoperating conveyors, coupled with the fiber placement head, each having an inlet that is configured to receive an end of composite tape from the composite tape source, an outlet configured to provide the end of composite tape to the fiber placement head, and one or more inline vacuum conveyors that are configured to receive compressed fluid from a source and direct the compressed fluid toward the outlet thereby transporting the end of the composite tape from the inlet to the outlet and into the fiber placement head.
- a fiber placement head assembly for applying a plurality of composite tape segments on a mold includes a fiber placement head that is configured to receive composite tape from a composite tape source and apply the composite tape to the mold; one or more air-operating conveyors, coupled with the fiber placement head, each having an inlet that is configure to receive an end of composite tape, an outlet configured to provide the end to the fiber placement head, and one or more inline vacuum conveyors that are configured to receive compressed fluid from a source and direct the compressed fluid toward the outlet thereby transporting the end of the composite tape from the inlet to the outlet and into the fiber placement head; and a plurality of composite tape sources each configured to releasably couple with the fiber placement head and including a pinch roller assembly that selectively supplies composite tape to the inlet of the air-operating conveyors.

- a fiber placement machine can use a robotic arm carrying a fiber placement head that releasably connects with a plurality of composite tape sources and automatically communicate the composite tape from a composite tape source to the fiber placement head.
- the fiber placement head can include tubing that receives compressed air from an air operating conveyor and extends from the composite tape source to the fiber placement head. The tubing can communicate composite tape from the source to the fiber placement head. After the fiber placement head attaches to the composite tape source, an end of the composite tape can be positioned at an inlet of the tubing.
- the air operating conveyor can feed compressed air or fluid into the tubing in one direction toward the fiber placement head thereby drawing the composite tape from the composite tape source at the inlet of the tubing and sending the composite tape end to an outlet of the tubing to a roller of the fiber placement head where the composite tape can be controlled by the head and applied to the mold during formation of the composite workpiece.
- Composite tape used to create composite workpieces is often comprised of fibrous material which has been impregnated with a resin that later provides strength to the composite workpiece after the resin is activated with heat. This is often referred to as “pre-preg” composite.
- a composite material is carbon fiber.

- the air-operating conveyor 26 includes an outlet 90 near the fiber placement head 14 (shown in FIG. 3) where the composite tape can be delivered. In one embodiment, the outlet 90 is positioned adjacent the upper feed roller 46 or the lower feed roller 48.
- FIGS. 7-8 another implementation of a composite tape source 24 and air-operating conveyor 26 is shown.
- the implementation shown in FIGS. 7'8 is similar to what is shown in FIGS. 5'6 but lacks the pinch roller assembly 76. Instead, the pinch roller assembly can be replaced with a passive redirect roller 82’.

- One implementation of the inline vacuum conveyor 88 is described using the name “Line VacTM” and sold commercially by the Exair Corporation. While the embodiment described above depicts one air-operating conveyor and one source, it should be appreciated that different implementations can use a plurality of air-operating conveyors, such as one for each of a plurality of composite tapes that are simultaneously applied to the mold by the fiber placement head. Or in some implementations one segment of tubing 86 can include more than one in-line vacuum conveyor 88.
