Abstract: Provided is an exhaust recycling system, which can burn and remove efficiently a VOC in an exhaust gas discharged from a predetermined zone and which can recycle the clean air after the removal of VOC. Also provided is a technique capable of stabilizing the concentration of the VOC contained in the exhaust gas to be fed to an adsorption apparatus. The exhaust recycling system comprises a coating zone (111) for discharging the exhaust gas containing the VOC, an adsorption apparatus (200) for adsorbing the VOC in the exhaust gas discharged from the coating one (111), and a clean air recycle apparatus for releasing the VOC adsorbed by the adsorption apparatus (200), from the adsorption apparatus (200), thereby to make the adsorbed VOC into a combustion fuel for a regenerative combustion apparatus (300), and for introducing again the clean air cleaned by passing through the adsorption apparatus (200), into the coating zone (111).

Abstract: A paint booth that eliminates paint mist from air containing paint mist and volatile organic compounds (VOC) generated within a paint room in a highly-efficient manner is provided. The paint booth includes a collecting chamber that holds booth circulating water and is provided with a forced contact section having curved guide plates. An end section of each of the guide plates is provided with a water surface plate. The water surface plates are made of plate-shaped members and are disposed above the surface of the booth circulating water that serves as collecting water, such that a necessary space between the water surface plates and the water surface is maintained. Preferably, the water surface plates are formed in a flat or corrugated sheet shape.

Abstract: Water is sprayed from a water nozzle of a water-washing device to wash polluted air in a painting booth, and then, a liquid polymer substance having a character to adsorb a VOC is spayed from an adsorbent spraying nozzle to remove the VOC from the air. A baffle is provided in a discharge duct to prevent the VOC-contained mixed liquid mist from moving with the air. Namely, by causing the air to hit the baffle, the VOC-contained mist turns into drops. Through the water-washing by the water-washing device, VOC adsorption by the mixed liquid and mixed liquid mist removal by the baffle, the polluted air can be sufficiently purified.

Abstract: A coating system for forming a protective layer includes first through fourth robots which are controlled by a controller and are provided close to a transport line, and sprayer mechanisms provided on ends of arms of the first through fourth robots. The motions of first through fourth robots are taught. Liquid material including an acrylic copolymer is sprayed onto an object such as a vehicle body, and dried to form a peelable protective layer on the object. The liquid material is sprayed from a first through fifth sprayers of the sprayer mechanism after the vehicle body is painted. At this time, the liquid material from the first sprayer is distributed locally in the smallest area. The area where liquid material is sprayed becomes wide gradually, in the order of the third sprayer, the fourth sprayer, the fifth sprayer, and the second sprayer. Such sprayers are also arranged in this order from an edge of the vehicle body.

Abstract: A method of applying a protective layer forming material, wherein when a roller is rolled against a curved portion of a vehicle to apply the protective layer forming material, the roller is rolled at a speed that is lower than a speed when the protective layer forming material is applied by rolling the roller over a generally flat portion of the vehicle. When the roller is rolled against a portion of the vehicle having recessed and projected grooves, in order to apply the protective layer forming material, an axis of the roller is positioned generally horizontal to an extending direction of the grooves and the roller moves in a direction generally perpendicular to the extending direction of the grooves, while the roller is rolled at a speed that is lower than a speed when the protective layer forming material is applied over the generally flat portion.

Abstract: A coating system using a protective layer forming material includes a coating device which is movable according to information taught by an operator, and disposed adjacent to a transport line for an object to be coated. The coating system includes a roller mechanism having a roller and a cushion mechanism. The roller is connected to the coating device. The coating system further includes a supply mechanism which supplies liquid material to the roller. The liquid material is dried to form a peelable protective layer on the object. A force is applied to the roller on an external surface of the object through the cushion mechanism. The roller is lifted and lowered corresponding to unevenness of the external surface.

Abstract: A coating system (10) for forming a protective layer includes a roller mechanism (34) provided at an end of an arm (46) of a robot (16a) as an end effector. The roller mechanism (34) has a roller (48), a holder (86) for supporting the roller (48), and a pipe (112). The holder (86) is removably attached to the roller (48). The pipe (112) supports the roller (48) in a freely rotating manner, and delivers the protective layer forming material to the roller (48).

Abstract: A robot capable of teaching operation is installed in the vicinity of a transfer line in which a plurality of vehicles are successively transferred. The robot is provided with a roller which is rotatable and made of a material capable of absorbing and storing a protective layer forming material. A controller for controlling the robot receives a production control information from a production control information supply section and recognizes the number of coating-unnecessary vehicles continuously transferred, on the basis of production control information (step S201). When the number of coating-unnecessary vehicles successively transferred is three or more, the roller is moistened (step S203). When the number of coating-unnecessary vehicles successively transferred becomes two, moistening is terminated and a preparatory operation is performed (step S207).

Abstract: A coating system (10a) has a first coating station (ST1), a second coating station (ST2), and a third coating station (ST3), which are successively arranged downstream with respect to the conveying direction of vehicles (14). Each of the coating stations has a plurality of robots (16). In the first coating station (ST1), mainly an entire upper surface of the vehicle (14) is supplied and roughly coated with a protective layer forming material. In the second coating station (ST2), the roughly applied protective layer forming material is spread. In the third coating station (ST3), the protective layer forming material is finished.

Abstract: Robots 16a, 16b, 16c which are able to be motion trained and controlled by controller 18 are established in close proximity to transport line 12. A roller mechanism 34 with a roller 48 made from a material which absorbs and holds protective layer forming material is established at the tip end of each robot 16a, 16b, 16c. Protective layer forming material uses an acrylic type copolymer material which forms a peelable protective layer when dried. Controller 18 records the training data which trains robots 16a, 16b, 16c to rotate and move so that roller 48 contacts vehicle 14, and vehicle 14 which has finished with painting is introduced; robots 16a, 16b, 16c are made to move according to the training data, protective layer forming material is supplied to roller 48, and protective layer forming material is applied to vehicle 14. To automate the process of applying protective layer forming material, to improve production efficiency, to simplify operations, and to make application quality consistent.
