2. Description of the Related Art A cast iron pipe manufactured by a centrifugal casting method has a cement lining layer formed on the inner surface after polishing and finishing the inner and outer surfaces to prevent corrosion by running water passing through the pipe and to It is designed to prevent foreign matter from entering. On the other hand, since the outer surface of the pipe is buried in the ground, a liquid or powder paint is applied to form a corrosion-resistant coating film in order to prevent corrosion due to moisture in the earth and sand. By the way, as is well known, one end of a cast iron pipe is joined to the other end with the other end being the receiving end, but since the water seal packing is fitted on the inner surface of the receiving end, the entire surface is reached until it reaches the flange surface of the pipe end. It is not possible to apply a cement lining layer on the surface, and its range is limited to the straight part from the insertion port to the step 15 on the receiving side, and from this step to the front surface 14 at the end of the receiving tube as with the outer surface, it is possible to use a paint. It is set to be painted to prevent corrosion.

The external surface coating of cast iron pipes is entirely carried out by a mechanical automatic device. In addition, even for the lining of the inner surface, it can be installed with almost no manual labor by an automatic device. However, the receiving port has a flange protruding from the pipe end, and a large number of mounting holes parallel to the pipe axis penetrate through the flange, and it is necessary to evenly coat the inner surface of the hole. There is a problem that it is difficult to do. On the other hand, with respect to the inner surface, there is a step forming a boundary between the cement lining layer and the exposed area of the inner peripheral surface of the pipe as described above,
When the coating scatters beyond this boundary and adheres to and contaminates the film of the cement lining layer, it is severely checked and the inspection cannot be passed, so there is a problem to be repaired.

Conventionally, since it is difficult to automate the coating of this portion, it is unavoidable to rely on the hand-painting by a worker in particular, and the cast iron pipe is evenly overlaid while rolling on a roller. The layers are formed, but this is an extremely laborious task and the daily throughput is a large number of hundreds, so it is very tired and smeared for that.
Paint defects such as paint pools may occur, and a particular problem is that there are many mistakes that the brush is applied onto the cement lining layer when the hand is slightly misaligned, so repairing defects due to this cause It was a factor that greatly affected productivity.

Japanese Patent Publication No. 2-23228 is an automatic coating apparatus which solves this problem. In this prior art, as shown in FIG. 3, a cast iron pipe 1a is horizontally supported, rotated at a required speed, and is first mounted on a carriage 4a that horizontally moves toward the inner surface of the socket 11a of the cast iron pipe. The elevating frame 101 is mounted, the spray nozzle 5a is movably attached to the tip of this frame, and only the parallel portion of the inner surface of the receptacle is spray-painted. On the other hand, separately from this, the second elevating frame 102 is suspended from the upper frame 103, and the brush 105 is attached to the tip of a horizontal lever 104 pivotally supported to the elevating frame.
Since the area around the step 15a at the deepest part of the receiving opening is attached with a brush, it is said that the paint is prevented from being accidentally applied onto the cement lining layer and spoiled.

The prior art shown in FIG. 3 has certainly made it possible to replace the conventional hand painting with a mechanical method and almost automatically paint the inner surface of the receiving port of the pipe. In particular, the two-stage coating method is rational, in which the paint on the inner surface is finished by spraying the paint from the spray nozzle and then the equipment is operated to switch the paint tool to the brush and paint only the stepped portion. It is evaluated as a simple idea. However, on the other hand,
This idea is complicated because the device has two stages, and the position change between the spray nozzle and the brush is constantly repeated. Since it always involves forward and backward movements to hesitate, this movement distance is quite large, but it is also not possible to operate the lifting frame at such a high speed. It must be said that this is one of the problems that adversely affects workability in order to flow hundreds of cast iron pipes of various diameters without stagnation. Furthermore, the problems unique to cast iron pipes remain
ing. Cast iron pipes are mass produced by centrifugal casting
However, after solidification of the molten metal, the temperature is lowered in a stationary state and further heat treatment is performed.
receive. Circumferential direction depending on the position of the cast iron pipe during this period
Direction and pipe axis direction are accompanied by a slight distortion, and the whole is in all directions.
It is not uniform. Variation allowed by the standard
Shape limits are specified and visual inspection is performed based on them
However, subtle deformation cannot be ignored in the painting process both inside and outside.
Is an element. As in the prior art of FIG. 3, the paint injection nozzle
If you proceed in a straight line in the pipe, of course due to this fluctuation the injection
Since the gap between the mouth and the surface to be coated cannot be avoided,
In a sense, the cause of uneven coating due to the distance of the spraying distance
It is easy to become. This is a problem unique to painting cast iron pipes.
Whether or not there is a function to absorb the perspective of this injection distance
There is undeniable concern that it may have a subtle effect on the quality of.

When the coating in the dipping tank is completed, the detecting means on the base 4 is operated to detect the position of the front surface 14 of the flange 13 of the cast iron pipe. Since the range required for the inner surface coating of cast iron pipes is determined for each pipe type, masking masking with the paint injection nozzle 5 attached to the detected position as the starting point
The distance that 51 has to travel on the base 4 is also specified. That is, the coating distance by the paint injection nozzle 5 is immediately determined if the pipe type is known. Therefore, when the pipe type is input, a matching operation amount is set immediately, and the masking masking 51 is moved forward until the required distance is completed. Works. Since the tip of the paint injection nozzle 5 sprays the paint onto the inner surface of the rotating cast iron pipe while spraying the paint, a uniform coating film is formed over a predetermined range as the paint moves. In this case, the paint spray from the paint spray nozzle 5 spreads divergently at some angle. Therefore, when approaching the step that hits the boundary, the paint sprayed to the top of the cement lining layer 12 is scattered and the surface thereof is scattered. there is a risk of contaminating the but shielding masking 51 engaged with this coating material injection nozzle 5 Roh
Since the paint immediately before the sledge is advanced at the same speed, all the scattered paint does not reach the surface of the cement lining layer, and the surface of the cement lining layer is maintained as it is without being contaminated by the masking masking 51. This masking mask 51
Fan-shaped plate forming the front surface of the shielding masking 51 during the forward movement of
The roller 55 pivotally supported at the lower end of 52 is located inside the cast iron pipe receiving port.
Since it abuts on the surface and swings in response to the fluctuation of the inner surface,
The tip of the paint injection nozzle 5 that moves with this swing is always received.
Since the relative distance from the inner surface of the mouth is kept constant, cast iron pipe
The subtle fluctuations of each time are completely
Develops an absorbing effect.
