Are installed, and the receiving members 70 made of a cushion material are attached to the conveyor 7 at predetermined intervals.

The operation of the surface cleaning apparatus of the first embodiment will be described below together with the first embodiment of the surface cleaning method. The unillustrated base pipe (outside diameter 29.92 mm, inside diameter 28.5 mm) made of an aluminum alloy pipe extruded by the hot extrusion device
The pull-out bench 10 is loaded into the pull-out bench 10 of FIG.
Is used for drawing at a speed of 10 to 20 m / min.

When the surface cleaning apparatus a is started, the traveling table 2 is located at the right end portion of the guide rail 21 as shown in FIG. 3, and the movable member 30 is retracted from the processing position b as shown by the chain double-dashed line in FIG. And each clamp member 3, 3 and 3
The openings a and 3a are larger than the diameter of the tube 1.

A handling device 11 for each drawing process
Holds the tube 1 by descending to the drawing level of the drawing bench 10 and moving it up, in parallel, and down to move the tube 1
Is transported to the processing position b, and is transferred to each support 6 that has been raised to the processing position b. When the pipe 1 is transferred to the support 6, the handling device 11 returns to above the drawing bench 10 as shown by the solid line in FIG.
Holds the end portion 1a of the tube 1 in a clamp shape and positions the tube 1.

After the positioning, the clamp members 3, 3 and 3a, 3a are moved to the movable member 3 by the actuator 35.
By the operation of 0, the pipe 1 is advanced to the processing position b of the pipe 1 together with the pouring pipes 4, 40, 41, and the pipe 1 is sandwiched by the actuators 33. Due to this pinching action, each wiping material 32 is pressed against the peripheral surface of the tube 1 with a pressure of approximately 20 kg. At the same time that the pipe 1 is sandwiched by the clamp members 3 and 3a, an organic solvent (kerosene in this embodiment) is poured out from the pouring pipes 4 and 40, and the traveling table 2 is pulled out to the left end direction in FIG. Drive at about the same speed. At this time, the solvent is poured out only from the pipes 4 and 40 which are located below the clamp member 3 or 3a in the traveling direction of the traveling platform 2 (the side). Each support 6 descends to a position where it does not interfere with the clamp members 3 and 3a when the traveling platform 2 approaches, and rises to the processing position b when the traveling platform 2 moves away.

As the traveling platform 2 travels, the pipes 4,
The organic solvent poured from 40 to the pipe 1 is absorbed by each wiping material 32 through the surface of the pipe 1, and the wiping material 3
Moisten 2 At the same time, the surface of the pipe 1 is strongly wiped by each wiping material 32, so that the carbides and other foreign substances that are firmly attached to the surface of the pipe 1 are melted by the organic solvent by each wiping material 32. Wiped off. When the surface of the pipe 1 is cleaned by the wiping, the respective supports 6 descend simultaneously, and the pipe 1 is received by the receiver 70 of the stock conveyor 7 stopped below the processing position b, and this stock is used. By the intermittent operation of the conveyor 7, it is carried to the left in FIG. Thereafter, the pipe 1 is cut into a predetermined product size, washed by immersion cleaning with an organic solvent or other cleaning liquid or shower cleaning, and dried.

The amount of the organic solvent poured out from the pipes 4 and 40 is not for the purpose of cleaning the pipe 1 but for each wiping material 3
Since it is sufficient to make 2 wet, it is a small amount. Specifically, it is set according to the traveling speed of the traveling table 2 and the material of each wiping material 32. When the clamp member 3 reaches the left end of the pipe 1 in FIG. 3, the traveling platform 2 is stopped and the pouring of the organic solvent from the pipes 4 and 40 is stopped. Then, the clamp members 3, 3 and 3a, 3a are opened, the movable member 30 is retracted to the position indicated by the chain double-dashed line in FIG. 2, and the carriage 2 is returned to the original position in FIG.

If the adhering material on the surface of the pipe 1 cannot be completely wiped off by the wiping materials 32, 32 simply by moving the traveling table 2 from the right end to the left end of the rail 21 in FIG. The traveling platform 2 can be reciprocated along the guide rails 21. In this case, when the traveling platform 2 travels from the left end portion to the right end portion in FIG. 3, the organic solvent is poured out from the pipes 40 and 41 and the pouring out from the pipe 4 is stopped. When the traveling platform 2 is stopped, the pouring of the organic solvent from the pipes 40 and 41 is stopped, and the clamp members 3, 3 and 3 are stopped.
While opening a and 3a, the movable member 30 is retracted to the position of the chain double-dashed line in FIG.

In the pipe surface cleaning method and apparatus of this embodiment, as described above, the wiping material 32 moistened with the organic solvent is pressed against the peripheral surface of the pipe 1 to strongly wipe it. It is possible to effectively remove carbides and other foreign matters that are firmly attached to the surface of the pipe 1. The drawn tube 1 is wiped by the wiping material 32 that has been wetted by the solvent shortly after the drawing, that is, while the temperature due to the drawing does not drop to room temperature, so that the deposits on the surface are better. To be removed.

The apparatus of this embodiment is, as described above, a tube 1
Since the traveling table 1 can be reciprocated once or several times while the wiping material 32 is pressed against the peripheral surface of the
Even if the surface of the tube 1 is persistently adhered,
It can be completely removed. As described above, when the clamp members 3 and 3a of each pair are formed in a split shape so that the inside has a semicircular shape, the portion through which the seam of the wiping materials 32 and 32 of each pair passes is It may be difficult to remove deposits on the surface of the tube 1, and traces of passage of joints may remain on the surface of the tube 1. However, in the apparatus of this embodiment, the clamp members 3, 3 of one pair are different in the sandwiching direction from the clamp members 3a, 3a of the other pair, and the wiping material in each pair of clamp members 3, 3a is different. Since the seams of 32 and 32 do not pass through the same place on the surface of the pipe 1,
There is no problem as mentioned above. Further, the clamping pressure of the clamp members 3 and 3a is hard to be applied to the seam portion, but the clamping pressure at the seam portion is reduced by making the clamping direction of each pair of clamp members different as described above. Since the thickness can be corrected, the deposits on the tube surface can be removed more effectively.
