This frame alignment tab (49) cooperatively interacts with the frame (60) for holding the polishing system, such that once the window positioner device (40) is secured in a proper position on the side of the aircraft, such that it is properly positioned over the window to be polished, the frame (60) for holding the polishing system is automatically located over that frame alignment tab (49) in a correct position for the attachment of the frame (60) to the side of the aircraft. Once the frame (60) for holding the polishing system is attached at the proper location on the side of the aircraft, the window positioner device (40) can be removed and is ready for use with the next window to be polished. - The frame (60) for holding the polishing system includes components which support the robot seat frame system (70). In one embodiment, as shown in
FIGS. 4A and 4B , this frame includes two parallel top to bottom frame members (62, 63) and two parallel left to right frame members (64, 65). These frame members may be manufactured from any sturdy but light material which is sufficiently strong to support the robot (90) and the other components of the machine (10). These frame members are connected together to form a rectangular shaped frame, as shown inFIG. 4B . The frame (60) for holding the polishing system is attachable to the side of the aircraft by any conventional attachment system. For example, a series of suction cups (66) may be secured to the back of the frame. These suction cups can be used to secure the frame (60) to the side of the aircraft. The frame (60) is properly positioned around the window to be polished by its interaction with the window positioner device (40). In one embodiment the upward extending, frame alignment tab (49) of the window positioner device (40) fits into a slot (not shown) that has been cut into, or formed as a component of, the top frame member (64) of the frame. When the tab (49) of the window positioner device is placed in this slot at the top frame member, the frame is automatically located in the proper position on the side of the aircraft in relation to the window to be polished. In one embodiment, as shown inFIG. 7 , a series of frames (60) can be secured to the side of the aircraft over the windows to be polished. - Secured to this frame (60) is the robot seat frame system (70). This robot seat frame system (70), as shown in one embodiment in
FIGS. 5A and 5B , holds the robot (90), the polishing pads placed in a polishing pad receptacle (71), a polishing pad removal device (81), a bin for used pads (82) and other components useful for the polishing of the aircraft windows. - In one embodiment the robot seat frame system (70) includes two parallel right to left frame system supports (72, 73) and two parallel top to bottom frame system supports (74, 75), as shown in
FIG. 5B , which are connected together to form a rectangular frame system. Attached to the top to bottom frame system supports (74, 75) are a pair of extension frame members (76), extending outward from the rectangular frame system to support a support frame (79). Connected to the top to bottom frame system supports (74, 75) and the extension frame members (76) is the support frame (79) which supports a robot mounting platform (78), which can be any conventional size and shape that supports and holds the robot (90). Preferably, this mounting platform (78) is secured to the support frame (79) and holds the robot (90) securely in place. This component is discussed in more detail. Also secured to the robot seat frame system (70) may be other components, such as the polish pad removal device (81), which is also discussed in more detail. - The robot seat frame system (70) is secured to the frame (60) for holding the polishing system by any conventional means. In one embodiment a top, downwardly extending tab (77), which is secured to the lower edge of an extension (72 a) of the upper, left to right frame system support (72), is placed within a slot (64 a) cut into the top frame member (64). By placement of this slot (64 a) at the top of the frame (60) at a particular location within the frame for holding the polishing system, and aligning it with the downwardly extending tab (77) of the robot seat frame system (70), the robot seat frame system (70) is placed in precise alignment directly at the proper position for polishing the aircraft window (20).
- In an alternative embodiment as shown in
FIGS. 9A and 9B an alternative robot seat frame system (70A) is secured directly to the aircraft (30). - Secured to the robot mounting platform (78) is any robot (90) useful for polishing the windows of the aircraft. In one preferred embodiment as shown in
FIGS. 1A and 1B the robot (90) is a six-axis robot, such as is manufactured by Mitsubishi and Stauby. Alternatively, the robot can have fewer axes as is well known in the art. This robot (90) is programmed and secured to the robot mounting platform (78). - It is important that the robot (90) be secured in the correct position directly in front of the window (20) and also be placed a proper distance away from the window. Any system which assures the proper placement of the robot in front of the window, a correct distance away from the window, is within the scope of the invention. In one embodiment the robot (90) is secured to the robot mounting platform (78), which is shown in
FIG. 5C . The robot mounting platform (78) is preferably secured to the front support (80) of the support frame (79). In one embodiment the robot mounting platform (78) can be moved side-to-side within slots (80 a) cut into the front support (80) of the support frame (79), as shown inFIG. 5C . This arrangement of slots (80 a) permits a side-to-side movement of the robot (90) on the robot mounting platform (78) in front of the window. Once in proper position the robot mounting platform (78) can be secured in proper position by the use of locking bolts (78 a). In addition, in another preferred embodiment, the front support (80) of the support frame (79) fits within slots (79 a) cut into the inside portion of the support frame (79), as shown inFIG. 5C . The relative position of the robot mounting platform (78) in relation to the window (20) of the aircraft can be adjusted by movement of the front support (80) of the support frame (79) in and out, closer and further away from the aircraft window. Once the proper position for the robot (90) has been determined, the front support (80) of the support frame (79) can be secured in position in the slots (79 a) in the support frame (79) by any conventional means, such as by the use of locking bolts (78 a). - In a preferred embodiment a polishing pad receptacle (71) is also secured to the robot seat frame system (70), as shown in
FIG. 5A . The robot (90) is programmed to remove abrasive pads from the polishing pad receptacle (71) and secure them to the end of its arm (92). As the six-axis robot applies the abrasive pads to the window (20) to be polished, lubrication is sprayed onto the window through a hose (not shown), preferably secured to the arm (92) of the robot (90). The hose is properly positioned so that the lubrication is sprayed only at the appropriate location on the window. Splash guards (83) are preferably provided on the side and top of the robot seat frame system (70) to prevent the lubricant from being sprayed onto the side of the plane itself, as shown inFIGS. 6A and 6B . Preferably, there is also secured to the frame (60), the robot seat frame (70), or the aircraft (30) itself a drain pan (84) with down spout (86), as shown inFIGS. 6A and 6B , which captures any liquid that falls from the window (20) being polished. - The polishing pads in the polishing pad receptacle (71) are preferably a series of pads with different degrees of abrasion capability. For example, in one preferred embodiment a series of pads (from 4 to 8 pads), each succeeding pad with a finer abrasion capability than the previous pad are placed within the receptacle. The robot (90) picks up the pads in sequence one after the other from the receptacle. The pads are secured to the end of the arm (92) of the robot (90) by any well known securing systems, such as hook and loop fasteners. Once the abrasives on the pad being used have been exhausted, the pad is removed from the end of the arm (92) of the robot and the robot is programmed to pick up the next abrasive pad. The abrasives that are on the pads may be any conventional abrasives and may include well known abrasives, including but not limited to, silica particles and industrial diamonds. In one embodiment, as shown on
FIGS. 5A and 5B the receptacle (71) is a cup which is secured within a support on the robot seat frame system (70). In addition to the abrasive pads that are placed within the receptacle (71), the top of the receptacle may be sealed with a conventional plastic seal prior to utilization. In use this seal is removed and the receptacle (71) is placed in its receptacle holder on the robot seat frame system (70). The abrasive pad which is secured to the end of the arm (92) of the six-axis robot (90) abrades the surface of the window (20) as its moves along the surface of the window. The end of the arm (92) contains an orbital or rotary pneumatic or electric motor which rotates the abrasive pad and exerts sufficient pressure against the window for the abrasive pad to remove the damage from the surface of the window. The arm (92) of the robot (90) retains the abrasive pad in position while it is abrading the surface of the window. The movements of the robot arm (92) are controlled by its programming and the selection of routines by the operator of the machine. After a predetermined period of time, the arm of the six-axis robot (90) disposes of the pad and picks up a new pad. The systems for retaining the pad on the arm of the robot and for replacing it with a new abrasive pad are well-known in the art and are controlled by the programming of the computer and the selections of routines by the operator. In one embodiment the pads are removed by operation of the polish pad removal gripper device (81 a), which device mechanically grabs the pad while on the robot arm and removes the used pad. These devices are sometimes referred to as a Zaytran robotic gripper magnum line. - Although the system described above describes the abrading of a single window, the robot (90) on the robot seat frame system (70) can be moved down the side of an aircraft by utilization of a series of frames (60), which are secured together end-to-end, as shown in
FIG. 7 . Alternatively, a rail system (96) can be secured to the side of the aircraft as shown inFIG. 8 to permit movement of the robot seat frame system (70) down the side of the aircraft. This rail system (96) can consist of a series of top supports on which the top of the robot seat frame system (70) is supported. With this embodiment it is not necessary to utilize the frame (60). - Once the windows on one side of the aircraft have been polished, the robot seat frame system (70) is removed from the frame (60) and then the frame is removed from the side of the aircraft. The machine (10) can then be installed on the opposite side of the aircraft (30) to polish the windows (20) located thereon.
- In an alternative embodiment, as shown in
FIGS. 10A , 10B, 10C and 10D, a polishing system (100) can be utilized, wherein the aircraft windows (120) are removed from the aircraft and secured onto a bench or console (110). Proper location of the aircraft window on the bench or console is provided by a window positioner device (140), which is securable to or a component of the bench or console. For example in one embodiment, the window positioner device (140) is a series of fixed or adjustable clamping blocks (142) on a drawer or support (144), as shown inFIGS. 10A and 10C . The drawer or support (144) may slide away from the top of the bench or support to assist in loading of the windows onto the bench. The aircraft window (120) is placed in a proper location on the drawer or support (144) and is then secured in that location by means of the clamping blocks (142). The particular location on the drawer or support is predetermined and is important so that the robot (190) polishes the aircraft window in a predetermined manner. The drawer or support (144) is placed in a fixed location on the bench or console. Also secured to the bench or console is a robot seat frame system (170) to which is secured the robot (190) with an arm for polishing the aircraft windows. Once again a six-axis robot can be utilized to move its arm and polish the window. Robots with 2, 3, 4 or 5 axis may also be used. In a further alternative embodiment, the robot (190) may be a Cartesian robot which moves in an X, Y and Z plane to polish the window as shown inFIG. 10A . The movement of the robot is controlled by programming from a control panel (180), which may be secured to the bench or console (110). Once the individual window (120) has been polished, it can be removed from the bench or console (110) and the next window can then be secured in position. - The devices discussed herein disclose some of the inventions.
