Abstract

Methods and systems for configuring a manual and/or automated processing system to conform to a contoured surface of a structure are disclosed. One example includes an automated processing system with a flexible rail configuration. One or more turnbuckles and/or other actuators configure and hold the flexible rail configuration into conformity with the surface (which could be flat or of a curvature) during processing by the automated processing system. Additionally, one or more combination suction-cup pressurized-air devices may be coupled to the flexible rail configuration for selectively attaching the flexible rail configuration to the contoured surface and also for selectively releasing and/or facilitating elevation and movement of the flexible rail configuration above and about the contoured surface. A multi-function end effector may be associated with the flexible rail configuration and be moveable relative thereto.

First claim

What is claimed is:

1. An apparatus for use in connection with a processing system on a surface having a contour, the apparatus comprising:
an elongated flexible component having a first portion and a second portion;
an actuatable component movable between a first position and a second position and having a first generally rigid portion and a second generally rigid portion;
a first bracket having a first portion and a second portion spaced from the first portion of the first bracket, wherein the first portion of the actuatable component is connected to the first portion of the first bracket, and the first portion of the elongated flexible component is generally fixedly connected to the second portion of the first bracket for movement with and flexure with respect to the first bracket;
a second bracket having a first portion and a second portion spaced from the first portion of the second bracket, wherein: the second portion of the actuatable component is connected to the first portion of the second bracket; the second portion of the elongated flexible component is generally fixedly connected to the second portion of the second bracket for movement with and flexure with respect to the second bracket; the actuatable component is configured to induce relative movement between the first bracket and the second bracket upon the actuatable component moving between the first position and the second position; and the elongated flexible component is configured to flex into a contour upon the relative movement between the first bracket and the second bracket;
an actuator that selectively moves the actuatable component between the first position and the second position; and
a turnbuckle threadingly connected to both the first portion and the second portion of the actuatable component, wherein the turnbuckle is configured, upon selective rotation thereof, to simultaneously move the first portion of the actuatable component and the second portion of the actuatable component outwardly relative to the turnbuckle or inwardly relative to the turnbuckle.

2. The apparatus of claim 1 , wherein:
the actuatable component, the first bracket, the second bracket, and the elongated flexible component are configured such that upon the actuatable component moving between the first position and the second position, the first portion of the first bracket and the first portion of the second bracket move away from one another, and the second portion of the first bracket and the second portion of the second bracket move towards one another.

3. The apparatus of claim 1 , wherein:
the actuatable component, the first bracket, the second bracket, and the elongated flexible component are configured such that upon the actuatable component moving between the first position and the second position, the first portion of the first bracket and the first portion of the second bracket move towards one another, and the second portion of the first bracket and the second portion of the second bracket move away from one another.

4. The apparatus of claim 1 , wherein the first portion and the second portion of the actuatable component are generally rigid.

5. The apparatus of claim 1 , further comprising:
a motor drivingly connected to the first portion of the actuatable component and to the second portion of the actuatable component and configured to selectively move the first portion of the actuatable component and the second portion of the actuatable component towards one another or away from one another.

6. The apparatus of claim 1 , further comprising:
a first motor drivingly connected to the first portion of the actuatable component;
a second motor drivingly connected to the second portion of the actuatable component; and
the first motor and the second motor being configured to selectively move the first portion of the actuatable component and the second portion of the actuatable component towards one another or away from one another.

7. The apparatus of claim 1 , wherein:
the first portion of the actuatable component includes a first fluid-actuated piston-cylinder device having a rod connected to selectively move the first portion of the first bracket towards or away from the first portion of the second bracket; and
the second portion of the actuatable component includes a second fluid-actuated piston-cylinder device having a rod connected to selectively move the first portion of the second bracket towards or away from the first portion of the first bracket.

8. The apparatus of claim 1 , wherein:
the first portion of the actuatable component includes a first cable connected to selectively move the first portion of the first bracket towards or away from the first portion of the second bracket; and
the second portion of the actuatable component includes a second cable connected to selectively move the first portion of the second bracket towards or away from the first portion of the first bracket.

9. The apparatus of claim 1 , further comprising:
at least one suction cup connected to the elongated flexible component that selectively attaches the elongated flexible component to the surface having the contour.

10. The apparatus of claim 1 , further comprising:
at least one pressurized air bearing connected to the elongated flexible component that facilitates movement of the elongated flexible component over the surface having the contour.

11. The apparatus of claim 1 , further comprising:
at least one suction cup connected to the elongated flexible component that selectively attaches the elongated flexible component to the surface having the contour; and
at least one pressurized air bearing connected to the elongated flexible component that facilitates movement of the elongated flexible component over the surface having the contour.

12. The apparatus of claim 1 , further comprising:
at least one support device coupled to the elongated flexible component, wherein the at least one support device is configured to selectively operate as one of a vacuum cup that selectively attaches the elongated flexible component to the surface having the contour and a pressurized air bearing that facilitates movement of the elongated flexible component over the surface having the contour.

13. A flexible rail of an automated system for processing a structure having a contour, the flexible rail comprising:
a first end and a second end;
combination suction cup-pressurized air devices coupled to the flexible rail;
a generally rigid first bracket including a first proximal end and a first distal end;
a generally rigid second bracket including a second proximal end and a second distal end, wherein the first proximal end of the first bracket is fixed to the first end of the flexible rail and the second proximal end of the second bracket is fixed to the second end of the flexible rail;
a generally rigid first pushrod having a first end and a threaded end, wherein the first end is pivotably coupled to the first distal end of the first rigid bracket;
a generally rigid second pushrod having a second end and a threaded end, wherein the second end is pivotably coupled to the second distal end of the second rigid bracket; and
a turnbuckle operatively coupled to the threaded end of the first pushrod and to the threaded end of the second pushrod.

14. The apparatus of claim 1 , further comprising a motor drivingly connected to the turnbuckle for selectively rotating the turnbuckle.

15. The flexible rail of claim 13 , further comprising a motor drivingly connected to the turnbuckle for selectively rotating the turnbuckle.
