  "abstract": "Provided is surface treatment system for a large object having high versatility. In a surface treatment system for a large object configured to cause a treatment machine for treating a surface of the object to be held by a leading end portion of a work arm of a work robot and to move the treatment machine relative to the surface of the object by a movement of the work robot thus treating the surface of the object by the treatment machine, there is provided a trackless type work machine mounting the work robot on a self-propelled cart. The work machine mounts a robot moving device for moving the work robot relative to the self-propelled cart at least in a height direction and mounts also a battery capable of supplying traveling power for the self-propelled cart.",
  "claims": [
    "1. A surface treatment system for an object configured to cause a treatment machine for treating a surface of the object to be held by a leading end portion of a work arm of a work robot and to move the treatment machine relative to the surface of the object by a movement of the work robot, thus treating the surface of the object by the treatment machine, the surface treatment system comprising: a trackless work machine mounting the work robot on a self-propelled cart; wherein the trackless work machine mounts a robot moving device for moving the work robot relative to the self-propelled cart at least in a height direction and mounts also a battery capable of supplying traveling power for the self-propelled cart; wherein the trackless work machine comprises, as the robot moving device, an extendible/contractible lift device configured to vertically move a lift table by an extension/contraction movement, and an extendible/contractible feeder device mounted on the lift table and configured to move a feeder table by an extension/contraction movement closer to or away from the lift table in the horizontal direction; wherein the work robot is mounted on the feeder table; wherein a control device is provided for controlling the lift device and the feeder device; and wherein the control device operates the lift device and the feeder device, based on distance information relative to the object determined by a movement distance sensor mounted on the feeder table.",
    "2. The surface treatment system of claim 1, wherein the trackless work machine comprises a power source connection section configured to receive supply of electric power from a power source section located nearest in its surrounding.",
    "3. The surface treatment system of claim 1, further comprising a plurality of trackless work machines comprising a high-place work machine mounting a robot moving device for a high place having a high maximum reach height in a movement of a work robot in a height direction and a low-place work machine mounting a robot moving device for a low place having a low maximum reach height in a movement of a work robot in the height direction.",
    "4. The surface treatment system of claim 1, wherein the trackless work machine mounts a plurality of kinds of the treatment machine that are exchangeable and detachably attachable to the leading end portion of the work arm respectively.",
    "5. The surface treatment system of claim 1, wherein the trackless work machine mounts a supply source device for supplying the treatment machine with a fluid to be used in a surface treatment of the object.",
    "6. The surface treatment system of claim 1, wherein the control device operates the lift device and the feeder device, based on the distance information relative to the object determined by the movement distance sensor and on three-dimensional shape data of the object."

  "description_excerpt": "This invention relates to a surface treatment system for a large object configured to carry out various surface treatments such as a cleaning treatment, a paint coat peeling treatment, a polishing treatment, a painting treatment, etc. on a surface of a large object such as an aircraft.\n\nMore particularly, the invention relates to a surface treatment system for a large object configured to cause a treatment machine for treating a surface of the object to be held by a leading end portion of a work arm of a work robot and to move the treatment machine relative to the surface of the object by a movement of the work robot, thus treating the surface of the object by the treatment machine.\n\nConventionally, an aircraft surface treatment system (see FIG. 18) disclosed in Patent Document 1 identified below includes a self-propelled cart 34 which travels along a guide wire 33 installed on a floor 32.\n\nFurther, this work machine 31 includes a rotary column 35 mounted vertically on the self-propelled cart 34 and an articulated type robot arm 36 which is elevated or lowered under a horizontal posture along the rotary column 35. And, a treating machine 37 for treating a machine body outer face of an aircraft W is mounted to the leading end portion of this robot arm 36.\n\nIn a ceiling section inside a building structure, a rail 38 is extended in correspondence with the aircraft W accommodated therein, and a movable device 39 driven to be movable along this rail 38 and the upper end portion of the rotary column 35 are connected to each other via a utility boom 40.",
