Description

200418580 Π) 发明 Description of the invention [Technical field to which the invention belongs] The present invention relates to a protective layer forming material coating system for applying a protective layer forming material on an object to be processed, and a method for protecting the object to be processed. Surface method, object to be treated, and peelable protective layer, in particular, a protective layer forming material coating system which can be used to apply a liquid and dried protective layer forming material after being dried, A method for protecting the surface of an object to be treated, an object to be treated, and a peelable protective layer. [Previous Technology] Vehicles such as automobiles are, in many cases, 'parked in a storage yard' after they are manufactured until they are delivered to a user, or they are transported by truck, ship, or similar vehicle . Because these vehicles are exposed to dust, metal powder, salt, oil, acids, and direct sunlight during storage and transportation, they will cause multiple layers to be coated on the outside surface of the vehicle during long-term storage and transportation. Risk of damage to the surface layer in the paint layer. From the standpoint of preventing such situations, a method is known for forming a peelable protective layer on a painted portion of a vehicle before the vehicle is transported (see, for example, Patent Document 1). This peelable protective layer is formed after the applied protective layer forming material (also called peelable paint) is dried to protect the painted part. In addition, the peelable protective layer can be easily peeled off when it is to be removed, and there is no risk that the peelable protective layer will peel off naturally during normal storage. -5- (2) (2) 200418580 During the application of the protective layer forming material before the peelable protective layer becomes dry, the protective layer forming material is first applied to the roller and is used in multiple operations. Personnel roll the roller to apply this protective layer forming material. From the viewpoint of automating the coating work to reduce the workload of the operator, and to provide uniform coating quality on the same day, it is proposed to use a material for forming a protective layer to be extruded onto the vehicle body, and thereafter A method of spraying air on the protective layer forming material to spread the protective layer forming material on the car body (for example, see Patent Document No. 2). According to this method, it is preferable that most of the work in the process of coating the δ-spread layer-forming material can be automated 'to reduce the workload of the operator and also improve the working time. In addition, in an assembly plant for manufacturing vehicles, some are covered with an experimental resin cover called a scratch cover to prevent the vehicle body from being scratched during the assembly operation. This scratch cover is provided, for example, on the front side of the vehicle body, and is removed before the vehicle is shipped from the assembly plant. Depending on the vehicle model, different shapes of scratch covers must be prepared. In addition, the number of scratch covers that must be prepared daily on the transportation line must depend on the number of vehicles planned to be produced daily. [Patent Document No. 1] JP-A-2001 -89 6 97 (paragraphs 0022 to 0027) [Patent Document No. 2] JP-A-8- 173882 (Figure 1) [Problems to be Solved] -6- (3) (3) 200418580 Incidentally, in the method disclosed in the second patent document, the protective layer forming material cannot necessarily be uniformly spread, and from the viewpoint of preventing the protective layer forming material from being scattered This method cannot be applied to the edge of the roof. In addition, in recent years, the shape of car bodies has become more complicated, and some car bodies have irregular parts and complicated curved surfaces. It is quite difficult to use air nozzles to spread the protective layer forming material on these irregular parts and curved surfaces. In addition, although it is necessary to apply a thick protective layer forming material at a place where a high paint quality is required, in the case of using an air nozzle to spread the protective layer forming material, it is necessary to adjust this. The thickness of the applied protective layer forming material is not easy. Therefore, after spreading the protective layer forming material by air nozzles, a digital operator is required to use a roller to apply the protective layer forming material to individual parts such as a roof edge part and an irregular part. Therefore, the coating of the protective layer forming material must be applied manually, so that the operator must bear a certain degree of workload, and the quality of the coating will vary according to the technology of the operator.

At the position of the vehicle 14, it can be set in any direction. In addition to the rotary actuation mechanism, the robots 16a, 16b, and 16e may have actuation parts capable of extending and retracting, discarding, and parallel link operations. The roller mechanism unit 34 is coupled to the distal end portion of the third arm 46, and a roller 48 is provided on the distal end of the third arm 46. The roller is cylindrical and has a width W. Made of material that absorbs and stores the protective layer forming material. The roller 48 is rotatably coupled to the holding portion 49, and the coating material line 22 is connected to the end of the holding portion 49. The protective layer forming material is supplied from the coating material φ stock line 22 into the axial center portion of the drum 48 and slowly oozes onto the surface of the drum 48. Sponges or brush sets can be used as the roller 4 8 material. In addition, the roller 4 8 can be disassembled from the holding part * 9 arbitrarily for replacement, cleaning and maintenance. As shown in Figure 4, 'a set of composite circuit (supply mechanism unit) 5 0 for supplying the protective layer forming material to the drum 48 ±' has a compressor 5 2, connected to the compressor 5 2 Air groove on the discharge part 5 4. Manual for switching the supply and cut-off of air pressure-13- (10) (10) 200418580 Air pressure input valve 5 6. Can be supplied according to the control unit 18 The regulator control valve 60 for reducing the secondary pressure by the electrical signal, and the regulator 58 which can reduce the pressure of the coating material line 22 by pilot control by the secondary pressure of the regulator control valve 60. In addition, the composite circuit 50 has an MCV (material control valve, which is a supply selector valve) 62 connected to the secondary side line of the regulator control valve 60, and a secondary side and a drum 48 provided on the MCV valve 62 Between the water line 26 and the trigger valve 64. The MCV valve 62 is provided with switching valves 62a and 62b for switching on and off the coating material line 22, and the secondary sides of these switching valves 62a and 62b are in communication with each other. The dotted line in Figure 4 represents the air pressure pipe line. The drive system of the MCV 62, the trigger valve 64, and the regulator control valve 60 is not limited to a pilot type of air pressure, and a drive system such as a solenoid may be used. The composite circuit 60 also has an MCV switching solenoid valve 66, which can pilot control the switching valves 6 2 a and 6 2 b by changing the air pressure input from the air pressure input valve 56 and a triggering switching solenoid valve 6 8 Is used for pilot control of the trigger valve 64. The MCV switching solenoid valve 66 can be connected to or cut off from the other by an electric signal from the control unit 18, thereby switching the supply of water and the protective layer forming material to the trigger valve 64. The trigger switching solenoid valve 68 can switch the trigger valve 64 between communication and shutoff to supply water or a protective layer forming material to the drum 48. The manual stop valves 70 and 72 are provided along the coating material line a] and the water line 26, respectively. Under normal circumstances, the stop valve and the 72 series are conducting -14- (11) (11) 200418580. A muffler 74 is provided at each of the air outlets of the composite circuit 50 to reduce exhaust noise. There are also pressure relief valves (not shown) for compressor 52, pump 32, and water supply source 24 to prevent excessive increase in air pressure. It is noted that in the composite circuit 50, the compressor 5 2, the air tank 5 4, the air supply source 24 and the pump 32 are shared by the robots 16a, 16b, 16c, and the other equipment is targeted at the robot 16a , 16b, 16c are set individually. Next, a method of applying the protective layer forming material to the vehicle 14 using the protective layer forming material application system 10 having the structure described above will be described. First, it teaches the robots 16a, 16b, and 16c how to operate in advance. These robots 16a, 16b, and 16c are assigned to the hood portion 14a (see FIG. 1), the center portion 14b, and the rear end portion 14c of the vehicle 14, respectively, and are taught to separate the protective layer A forming material is applied to these designated parts. The teaching data thus taught to these robots is stored and held in a predetermined storage location of the control unit 18. When the vehicle operator 4 is a car, the robot 16c is assigned to the luggage compartment. As shown in Fig. 5, the robot 16a assigned to the hood section 4 & is taught the movement trajectories 80, 82, 84, 86, 88, 90 so that the mother can't The protective layer-forming material is applied over the width W of the drum 4 8 ′ and the robot 14 a is taught not to leave any uncoated spaces particularly on the edge portions marked with shaded or oblique portions 92, 94 . Due to the mechanism of the robot 16a, the roller mechanism unit 34 (12) 200418580 3 4 can have six degrees of freedom in motion, so the roller mechanism unit can handle complex structures. For example, the roller mechanism unit 34 can be moved along the movement trajectory 84 to ensure that even a protective layer forming material can be applied to the air suction portion 96. In addition, it is also possible to prevent dripping or flow by appropriately adjusting the viscosity of the cover layer forming material, so it can be ensured that it can be used at 9 or 4 oblique line portions having a large angle inclined edge portion, and also to an appropriate protective layer forming material. Coating effect. In addition, it is also possible to apply the protective layer forming material to the vertical surface of the side of the vehicle 1 4 by setting the viscosity higher. Therefore, it can also protect the painted parts on the vertical surface without the risk of damage to the car body during the assembly operation, and the necessity of providing a scratch cover on these parts of the car body 14 can be avoided. After teaching the robots 16a, 16b, 16c to operate, the robots 16a, 16b, 16c can be controlled by, for example, the control unit i8, robot control 28a, or dedicated The controller 98 controls its actual actions. In this case, the 'operator is visually verifying that the wave ft] 4 8 is in contact with the vehicle 14 and teaches the robots 16a, 16b, and 16c to act. In addition, the teaching of action can also be carried out by adopting, for example, the so-called off-line teaching method, in which the teaching process is implemented using three-dimensional CAD (computer-aided design) using a solid model, without actually using the machinery 16a, 16b , 16c. In this case, for example, as shown in FIG. 6, it is set based on its shape data to an angle of 4 ° with a length L relative to the surface of the vehicle 14, and then the robot can be automatically set. The movements of 1 6 a, 1 6 b, and 1 6 c cause the axis line of the rolling mechanism single 3 4 to overlap with the vector V. The lacquer is applied in the shape of a human-shaped guide along the ready-to-serve area. 16- (13) (13) 200418580 This teaching process can be implemented so that the operation of applying the protective layer forming material can be performed on the needle conveyor line. Each vehicle on 12 is completed within the set working time of 14. When the person's coating material is applied to the vehicle 14, the barrel groove (see FIG. 4) and the coating material line 2 2 are heated by a predetermined heater to an appropriate temperature and started Compressor 5 2. Water supply 24 and pump 3 2. In addition, the robots 16 a, 16 b, and 16 c will be parked at positions that will not interfere with the vehicle 14 and the air pressure input valve $ 6 will be in a connected state. Secondly, the fully painted vehicles 14 will be transported by the transport line 12 and stopped near the robots 16a, 16b, 16c. The control unit 18 will confirm the arrival of the vehicle 14 through a signal or a sensor (not shown) sent from the transportation line 12, and make the robots 16a, 16b, 16c start according to the teaching data. Act. When this occurs, the control unit 18 controls the regulator control valve 60 (see FIG. 4) through the regulator 58 to control the coating material line 2 2 to a proper pressure. In addition, the control unit 18 can control the MC V 6 2 through the MC v switching solenoid valve 66 to communicate with the coating material line 2 2 and cut off the water line 26. In addition, the control unit 18 can control the trigger switching solenoid valve 68 to communicate the trigger valve 64. The protective layer forming material is supplied to the drum 4 8 of the drum mechanism unit 34 under the condition that the control unit 18 is operated in the above manner and is maintained at an appropriate pressure and temperature, and an appropriate amount of protection is provided. The layer-forming material flows onto the surface of the drum 48. In this way, the protective layer forming material can be applied to the vehicle 14. In addition to this -17- (14) (14) 200418580, the thickness of the protective layer forming material applied to the vehicle M can be controlled by controlling the pressure of the regulator 58 and through the movement speed of the robots Ua, and i6c. Adjustment. A vehicle that can be coated with a protective layer forming material in this way only needs to be painted already, not to mention that it does not need to be an assembly finisher with assembled components. The object to be applied may be the body of the vehicle 14, and the protective layer forming material is applied to the vehicle before the assembly of the vehicle I4 is completed. In this step, 'the other components such as glass and door are not installed on the vehicle body, so it can help the coating operation. In addition, by setting the step of applying the protective layer forming material immediately after the painting operation, it can shorten the time for the painted surface of the vehicle body to be exposed to the outside air. Protect the painted surface from dust. In addition, for example, in the case of a door, the protective layer forming material can be applied to the door separately during the manufacturing process of the door. · The vehicle 14 coated with the protective layer-forming material by the robots 16 a, 16 b, and 16 c is then transported by the transportation line 12 to the next processing procedure. The robots 16a, 16b, 16c will return to their waiting states without disturbing the vehicle 14, and so wait until the next vehicle is delivered. When this occurs, the trigger valve 64 is cut off to stop supplying the protective layer forming material. The protective layer-forming material thus applied can then be dried naturally, or dried by blowing to form a peelable protective layer 'which can protect the painted parts of the car -18- (15) 200418580. The peelable color 'formed when the protective layer forming material is dried may be made by adjusting the composition of the protective layer forming material, so that the color of the vehicle 14 can be distinguished. In addition, the peelable guarantee can also be translucent (or colored but still transparent) so that the color of the vehicle 14 is still recognizable. In addition, the person 'before the vehicle 14 is to be sold as a product', in more detail, 'the vehicle 14 is to be delivered to the user's hand.' This peelable protective layer can be stripped at the vehicle dealer by the responsible water. except. At this time, when high water is sprayed from the side or bottom π shell to the end of the protective layer, the layer can be peeled off in the form of a single-layer diaphragm. This technique can therefore be performed simply. In this case, a car wash sprinkler is used as the high-pressure sprinkler. In addition, the layer-by-layer coating system 10 using the protective layer forming material is uniformed, so the thickness is not small anywhere, so there is no risk of breakage during the stripping process, which can help the protection industry. In addition, there is no risk of peelability due to exposure to rain. Please note that in some cases, transport line 12 is used for models, or for the same model but different details. Refers to, for example, whether there is a sunroof hole 14 d (see Fig. 1 for the entry part 9 6 (see Fig. 5), a turning part (also known as the rear wing, etc.). It can handle the color of many different models and different protective layers. It is transparent, and the color of the protective layer is a certain degree. The personnel spraying the sprayer during the stage or before the stage does not need this peelable protection item. It can evenly apply the peelable protection and peel the protective layer. Layer stripping as a protective layer for natural peeling and transportation of various car detail structures), air suction as protrusions), detail structure, -19- (16) (16) 200418580 robot 1 6 a, 1 6 b, 1 6 c It teaches its operation according to each model and detailed structure. The control unit 18 will receive signals from the transport line 12 to indicate the vehicle model and detailed structure, and can select teaching data based on the received signals to control the robots 16a, 16b, 16c. In addition, when the work is completed or maintenance is required, it will control MCV 62 via MCV switching solenoid valve 66, and cut off switching valve 62a while supplying switching valve 62b to supply through water line 26 Water to clean MCV 62, trigger valve 64 and roller mechanism unit 34. Since the rollers 4 and 8 are detachable, the rollers 4 and 8 can be detached from the roller mechanism unit 34 separately and cleaned as a single body. As described above, according to the protective layer forming material coating system 10 provided by the present invention and the method for protecting the surface of an object to be processed, the coating process of the protective layer forming material can be automated so that it can be used by The robots 16a, 16b, and 16c operate the roller mechanism unit 34 provided with the roller 48 and supply the protective layer forming material to the roller 48 to obtain uniform coating quality, so there will be no insufficient thickness of the protective layer forming material. And the quality of the paint on the vehicle 14 as the object to be treated can be maintained for a considerable period of time. In addition, it can prevent the thickness of the peelable protective layer from being too thick, so that the protective layer forming material can be saved. In addition, since the work of applying the protective layer forming material by the worker can be overcome by the automation of the process, the number of processing procedures can be reduced, and the manufacturing efficiency can be improved. In addition, it is also possible to omit the air-conditioning equipment provided for the worker who performs the coating operation. For this reason, it can reduce the power required for air conditioning, thereby saving energy, and therefore can improve environmental efficiency. -20-(17) (17) 200418580 Fruit ’and the operating cost of the plant can be reduced. In the protective layer forming material coating system 10, although the previously described example is that the protective layer forming material is supplied from the pump 32 through the coating material line 22, for example, as shown in FIG. 7 It can also be provided with a support plate (supply mechanism unit) 100 for storing the protective layer forming material, and the roller 4 8 can be immersed into the supporting plate 100 first, and then the protective layer forming material is coated. Apply to vehicle 14. According to this structure, the composite circuit 50 can be omitted, and the structure of the system can be simplified. · This peelable protective layer made of the protective layer forming material can not only protect the painted part of the vehicle 14 after it is sent from the factory, but also can be used to protect the painted part of the vehicle 14 still in the factory. Therefore, it can replace the scratch cover. For this reason, 'it can omit a variety of scratch covers for different structures 〇ΓΓΠ. In addition,' it can also use the drip mechanism 10 2 (see Figure 7) to inject or spray the protective layer forming material on the vehicle in advance. 14, and then spread the protective layer forming material by rolling the same unit 34. In addition, the operator 14 can apply the final coating to the complicated structure or detailed parts of the vehicle 14 that cannot be automated by the robots 16a, 16b, and i6c. At this time, the number of places where the protective layer-forming material cannot be applied is reduced, and the workload of the worker can be greatly reduced. Although the bumper of the vehicle 14 is colored and therefore does not need to be painted, it may apply this protective layer forming material to a space other than the painted part 'including the bumper thus coated. -21-(18) (18) 200418580 In addition, the object to be processed that can be coated with this protective layer forming material is not limited to vehicles, but may also be an object to be processed such as a traffic sign board or a kanban installed along the road. . The device for applying the protective layer forming material is not limited to the robots 16 a, 16 b, and 16 c, and any device capable of operating according to the teachings may be used.
