An assembly system, such as welding system, includes an assembly station that is configured to assemble a component to a part in a loaded position. A drag conveyor includes a movable conveyor member that supports multiple locating elements configured to cooperate with a locating feature on a part. A friction bar is arranged along the locating elements, and the locating elements extend beyond the friction bar. The friction bar is configured to support the part and reorient the part from an unoriented position to an oriented position while the movable conveyor member drags the part along the friction bar. A robot is configured to transfer a part from the oriented position on the conveyor to the loaded position at the assembly station, such as a welding unit.

1. An assembly system comprising: an assembly station that is configured to assemble a component to a part in a loaded position;a drag conveyor includes: a movable conveyor member that supports multiple locating elements configured to cooperate with a locating feature on a part;a friction bar arranged along the locating elements, the locating elements extend beyond the friction bar, the friction bar is configured to support the part and reorient the part from an unoriented position to an oriented position while the movable conveyor member drags the part along the friction bar; anda robot configured to transfer a part from the oriented position on the conveyor to the loaded position at the assembly station. 2. The system according to claim 1, wherein the conveyor member is a continuous chain that supports the multiple locating elements. 3. The system according to claim 2, wherein the conveyor includes multiple rows of conveyor members with locating elements. 4. The system according to claim 2, wherein the locating elements are transfer pins. 5. The system according to claim 2, wherein the conveyor includes a sprocket coupled to the chain, and a support bar is arranged beneath the chain adjacent to the sprocket, the support bar configured to position the locating element as the locating element approaches an end of the conveyor. 6. The system according to claim 1, wherein the conveyor has an adjustment assembly connected to the friction bar and configured to move the friction bar relative to the locating elements. 7. The system according to claim 6, wherein the adjustment assembly includes a linkage interconnecting a cylinder to a frame that supports the friction bar, the frame configured to move vertically in response to the cylinder pivoting the linkage. 8. The system according to claim 1, wherein the conveyor includes a guide arranged on the friction bar adjacent to the locating element, the guide configured to reorient the part from the unoriented position to the oriented position. 9. The system according to claim 8, wherein the guide has a ramp configured to cooperate with a front of the part to lift the front off of the friction bar. 10. The system according to claim 1, comprising multiple conveyors, each conveyor configured to carry a different part. 11. A method of positioning a part with a conveyor, the method comprising the step of: manually loading a part onto a conveyor locating element in an unoriented position, wherein the conveyor locating element is carried by a conveyor member;dragging the part with the conveyor member along a conveyor friction bar to an oriented position; andpicking up the part robotically from the oriented position. 12. The method according to claim 11, wherein the multiple locating elements are arranged at a regular spacing, and the manually loading step includes manually loading parts onto the locating elements at an irregular spacing. 13. The method according to claim 11, wherein the locating element is a transfer pin, and the manually loading step includes placing the transfer pin through a hole in the part. 14. The method according to claim 13, wherein the dragging step includes pivoting the part about the transfer pin from the unoriented position to the oriented position. 15. The method according to claim 11, wherein the dragging step includes stabilizing the locating element near an end of the conveyor prior to performing the part picking up step. 16. The method according to claim 11, comprising the step of laterally adjusting a position of the part from a first oriented position to a second oriented position near an end of the conveyor prior to performing the part picking up step. 17. A method of positioning a part with a conveyor, the method comprising the step of: manually loading a part onto a conveyor locating element in an unoriented position;dragging the part with a conveyor member along a conveyor friction bar to an oriented position;picking up the part robotically from the oriented position; andwherein the manually loading step includes supporting the part on the conveyor friction bar, and comprising the step of adjusting a height of the friction bar relative to the conveyor locating element prior to the manually loading step. 18. The method according to claim 17, wherein the manually loading step includes manually loading parts onto multiple rows of conveyor locating elements. 19. An assembly system conveyor comprising: a continuous conveyor member that includes multiple transfer pins, at least one of the transfer pins configured to cooperate with a hole in a part;friction bars arranged along lateral sides of a row of the transfer pins, the transfer pins extend beyond the friction bars and are configured to move relative thereto, the friction bars are configured to support the part and reorient the part from an unoriented position to an oriented position while the friction bars are in a fixed position. 20. The assembly system conveyor according to claim 19, comprising a support bar arranged beneath the continuous conveyor member, the support bar configured to position the transfer pin as the transfer pin approaches an end of the conveyor. 21. The assembly system conveyor according to claim 19, wherein the conveyor includes a guide arranged on the friction bar adjacent to the locating element, the guide configured to reorient the part from the unoriented position to the oriented position. 22. An assembly system conveyor comprising: a continuous conveyor member that includes multiple transfer pins, at least one of the transfer pins configured to cooperate with a hole in a part;friction bars arranged along lateral sides of a row of the transfer pins, the transfer pins extend beyond the friction bars, the friction bars are configured to support the part and reorient the part from an unoriented position to an oriented position while the friction bars are in a fixed position; andan adjustment assembly connected to the friction bar and configured to move the friction bar vertically relative to the transfer pin.
