Description of the Related Art Generally, in an automobile production line, when an automobile placed on a trolley stops at a painting work place on the production line, a door is opened and painting is performed by, for example, a painting robot. In this case, for example, as shown in FIG. 4, first, the door 2 of the automobile 1 is, for example, the painting robot 3
It is opened by itself. Door 2 with the above painting robot
When the door is opened, the door 2 is fixed by the door fixing device 4 in order to maintain the open position of the door 2. That is, the raising / lowering lever 5 is driven to swing upward from the floor surface, and the pressing member 6 attached to the tip of the raising / lowering lever 5 is brought into contact with the inner surface side of the door 2.

のできる洗浄方法を提供することである。By the way, in recent years, for the purpose of improving the efficiency of production, a method of painting many kinds of automobiles on one production line has been widely adopted. Even if the above-mentioned door fixing device 4 is applied to the above, since the structure on the inner surface side of the door is different depending on each vehicle type, the pressing member 6 of the raising and lowering lever 5 can be used for all types of doors. Due to the action, it cannot be fixed in the open position. Therefore, a first object of the present invention is to provide a door fixing device capable of fixing the door in its open position in a suitable manner for the door of each vehicle type. Further, in the above-mentioned coating system, since the painting operation is performed while the fixing member is engaged with the door body, the coating material also adheres to the fixing member. Then, when the same painting operation is performed on another vehicle, the paint adhered to the fixing member adheres to the door of the other vehicle, resulting in a defective coating. Therefore, a second object of the present invention is to provide a cleaning method capable of efficiently cleaning the fixing member to which the paint is attached during the painting operation.

順について説明する。The fixing member 17 is made of, for example, a synthetic resin and is composed of a rotating body whose radial dimension gradually differs in the axial direction in a side sectional view, and its shape is a spherical shape as shown in FIG. Besides, an elliptical fixing member 18, an abacus fixing member 19 (see FIG. 3), and the like are possible. A cleaning device 21 having an opening 20 in the vertical direction is arranged on the base side of the base 8. The cleaning device 21
Inside the cover 22, a plurality of spray guns 23 are arranged in parallel in the vertical direction. Spray gun 2 above
3 has a function of injecting, for example, a thinner toward the peripheral surfaces of the bar 15 and the fixing member 17 which are inserted into the cover 22 through the opening 20 and driven to rotate, and clean the surfaces thereof. Incidentally, as described above, the curved surface of the fixing member 17 formed by the rotating body is engaged with the glass groove 16a of the door body 16 to fix the door body 16 in its open position. However, most of the automobile doors are provided with glass grooves, and the glass grooves are not so different in structure or shape.
Further, as shown in the figure, the door main body 24 not having the glass groove as described above and having the convex portion 24a as shown in FIG. 3 is located at a position separated by a predetermined dimension in the axial direction. It is preferable to use the fixing member 25 formed by arranging individual spherical convex rotating bodies. In this case, the convex portion 24a of the door body 24 is engaged with the groove portion formed between the rotary members,
The door body 24 is fixed in its open position. When the door body 16 is fixed in its open position by using the fixing member 25, one of the rotating bodies may be used to fix the door body 1.
The glass groove 16a of No. 6 may be fixed. or,
Instead of the fixing member 25, it is also possible to apply the fixing member 18 or 19 in which ellipse-shaped or abacus-shaped ones are arranged side by side at a predetermined distance in the axial direction of the rotating body. Is. Next, the operation of the door fixing device 7 having the above configuration and the procedure for cleaning it will be described.

乾燥時間は更に短縮される。First, when an automobile mounted on a bogie (not shown) is stopped at a predetermined coating work place on the production line, the opening / closing jig 27 of the door opening / closing device 26 is engaged with the door body 16. The door body 16 is opened by appropriately swinging each arm of the door opening / closing device 26.
Subsequently, the bar 15 of the door fixing device 7 is swung or slid in a proper direction, and the curved surface of the fixing member 17 provided at the tip of the bar 15 causes the glass groove 16 of the door body 16 to move.
It is engaged so as to be pressed downward from above by a. With the door body 16 fixed in its open position as described above, a painting robot (not shown) performs painting work on the inside of the vehicle body or the door body 16. When the paint adheres to the tip portion of the bar 15 or the surface of the fixing member 17 by repeated coating work, the surface is cleaned by the following procedure. That is, the bar 15 is driven to swing downward and is slidably driven, and the tip end portion of the bar 15 and the fixing member 17 are inserted into the cover 22 of the cleaning device 21. In this state, the bar 15 is rotationally driven on its axis, and at the same time, thinner is sprayed from the spray gun 23 toward the peripheral surface thereof. As a result, the tip portion of the bar 15 and the peripheral surface of the fixing member 17 are cleaned efficiently by the thinner from the spray gun 23. By taking such a cleaning procedure, the cleaning operation can be completed within a short time with a relatively small amount of thinner. Also, if the cleaning is performed while rotating the bar 15 as described above, the spray gun 2
3 may be arranged only in one direction with respect to the bar 15 and the fixing member 17, and can greatly contribute to downsizing and space saving of the cleaning device 21. Furthermore, since the fixing member 17 is a convex rotary member as described above, positioning of the bar 15 and the fixing member 17 in the rotational direction on the axis of the bar 15 after cleaning becomes unnecessary, and the control can be simplified. It can greatly contribute. The bar 15 and the fixing member 17 after being washed as described above are
By stopping the injection of the thinner from the spray gun 23 and rotating it at a high speed, the surface can be dried very efficiently. If drying air is blown in this state, the drying time is further shortened.
