Definitions

  • the present invention relates to a spray painting system, and more particularly to a spray painting system of a continous assembly line, the system including a plurality of work machines for spray painting disposed side by side along a direction for conveying a work object inside a spray painting booth.
  • each of a plurality of work machines 6 is arranged movable within a predetermined distance l (usually about 1 m) in the object-conveying direction on a mounting frame fixed on a floor surface of the booth.
  • l usually about 1 m
  • a paint robot 18 is disclosed displaceably mounted on guide rails 20 with the working area of the spray booth lower than the top of vehicle body 10 and accordingly is subject to a substantial spray mist environment.
  • a single rail 20 on one side is illustrated having a carriage 32 mounted on edge portions between which a rack 26 is provided.
  • GB-A-2098578 an industrial production system are disclosed a plurality of robotic operating arm structures 2 mounted on a single I sectioned rail 6 by means of carriages 8 with rail 6 being within the working environment space.
  • Support rollers 40 roll on the top surface of rail 6 and guide rollers 41 roll on the vertical sides of rail 6 directly beneath rollers 40.
  • Rail 6 is mounted along the top side edge of bench 7 which also supports workpieces.
  • a spray painting system having a plurality of work machines disposed side by side along the direction of conveyance of a work object to be sprayed inside a spray painting booth and having an upper rail and a lower rail for guiding the work machines to move along said conveying direction, with each of the machines running on said upper rail characterised by said upper rail being arranged in a region outwardly of the working area of said spray painting booth and positioned higher than at least said work object; said upper rail supporting the work machines so as to receive all the load therefrom, and said lower rail guiding said work machines without receiving any load from said work machines.
  • the rails guide the movement of the machines along path of travel of the work objects with the machines supported on respective frames and each machine being detachably supported on the respective frame.
  • the same upper and lower rails guide the movement of a plurality of work machines in the object-conveying direction with the machines running on the upper rail.
  • the system of the invention can readily cope with frequent position adjustment operations of the machines as required and also substantial changes in the work conditions without requiring total relocation of the machines. Consequently, the spray painting system of the present invention has achieved significant reduction in the shutdown period of the production line which used to be required for troublesome position adjustment or total relocation of the work machines, thus improving the entire operation efficiency of the production line including this system as well as other lines associated therewith.
  • the system can change the disposing order of the work machines in the object-conveying direction.
  • FIG. 1 through 4 illustrate a preferred embodiment of a spray painting system according to the present invention.
  • a tunnel-like spray painting booth 1 accommodates a conveyor device 1 for conveying an object 2 (an automobile body in the instant embodiment), an overhead outlet vent 4 for downwardly discharching a ventilation air and a demister 5 for eliminating spray mist contained in exhaust air by traping the mist in cleaning water.
  • a purality of work machines 6 for the spray painting with the machines being disposed side by side along a direction of conveying the object 2 inside the booth.
  • the work machines 6 comprise various kinds such as one-hand robbot 6a for opening and closing doors of the object 2, i.e. automobile body, a further one-hand robbot 6b for controlling a spray gun 7a to spray-paint interior surfaces of the object 2, a side-face spraying machine 6c for vertically moving a spray gun 7b to spray-paint side outer surfaces of the object 2, an upper-face spraying machine 6d for controlling rotary, reciprocating and vertical linear movements of an arm 7d equipped with a spray gun 7c so as to spray-paint upper surfaces of the object, and a touchup spray painting, one-hand robbot 6e for controlling a further spray gun 6e to effect a touchup spray-paint operation on the object.
  • one-hand robbot 6a for opening and closing doors of the object 2, i.e. automobile body
  • a further one-hand robbot 6b for controlling a spray gun 7a to spray-paint interior surfaces of the object 2
  • each frame 8 has a first roller 10a for rolling on an upper face of the upper rail 9a with the weight of the frame 8 being supported by the rail 9a, a pair of second rollers 10b lie astride the upper rail 9a and a pair of third rollers 10c lie astride the lower rail 9b.
  • the frame 8 also has a pair of free sprockets 12a engageable with the chain 11, a drive sprocket 12b which comes into engagement with an inner side of the chain 11 which is formed like a reversed letter U-shaped as being entrained about the two free sprockets 12a, and a motor 14 for driving the drive sprocket 12b via a reduction mechanism 13.
  • the frame 8 i.e. the work machine 6 mounted on this frame
  • the frame 8 is self-movable along the object-conveying direction within the range determined by the length of the upper and lower rails 9a and 9b, while the chain 11 acting as resistance againt react ion force associated with the movement of the frame 4.
  • the setting position of the work machine 6 has be changed to cope with various changes in the operating conditions such as in the type of paint, the spray guns 7a, 7b, 7c and 7e and/or in the shape of the object 2, i.e. the automobile body
  • the position adjustment is readily possible by selectively and independently causing the machines 6 to self-move along the object-conveying direction.
  • an operator box 15 having a length extending over the entire length of the rails 9a and 9b is integrally attached to the booth side wall 1a; and the booth side wall 1a has a window 16 for allowing an operator inside an operator chamber 15a of the box 15 to inspect and watch the spray painting operation taking place inside the booth.
  • a partition 11 is provided for forming an upper section 15b separately from the operator chamber 15a.
  • the upper section 15b accommodates paint hose-cable means 18 such as paint hoses, electric cables and pressure-air hoses for feeding paint, electricity and pressure air to the respective work machines 6; flexible means 19 such as flexible cable racks for allowing movements of the work machines 6 along the conveying direction and further the upper rail 9a and the chain 11.
  • the upper section 15b further accommodates a shaft 14a for operatively connecting the motor 14 and the drive sprocket 12b and an opening S for inserting the hose-cable means 18 therethrough.
  • control panel 22 for remote-controlling the work machines 6.
  • control panel means 24 such as electric control panels and pressure-air control panels.
  • the operator chamber 15a is connected with a duct 21 having a dumper 20 for forcibly introducing ventilatin air from a air feed chamber 4a through the overhead outlet vent 4 into the chamber 15a.
  • Numeral 25 denotes a grating floor used for e.g. a system maintenance operation.
  • This grating floor 25 is provided only at a certain region inside the booth along the object-conveying direction.
  • the machine 6 to be maintained is driven to self-move to the region of the grating floor 25.
  • the grating floor 25 is provided only at a certain region inside the booth, cleaning operation of this grating floor 25 to eliminate excess paint adhered thereto is required less frequently than the conventional system in which the grating floor is provide over the entire booth floor.
  • this grating floor 25 movable in the object-conveying direction.
  • the setting location of the grating floor 25 can be changed in accordance with the necessity and convenience.
  • the types of the work implements used for spray painting operation are not limited to those described in the foregoing embodiment.
