【Example】

 Hereinafter, the present invention will be described in detail with reference to an embodiment shown in the accompanying drawings. 1 is an overall front view showing an embodiment of a marking device for an outer peripheral surface of a steel pipe according to the present invention, and FIG. 2 is a side view excluding a pipe rotating device.

In these drawings, reference numeral 1 denotes a plurality of turning rollers arranged in series, which are configured to be rotationally driven by, for example, a motor 2 via a power transmission mechanism such as a chain 3. Reference numeral 4 denotes a free roller arranged in parallel with the turning roller 1, which is rotatably supported. The turning roller 1 and the free roller 4 are pivotally supported on the same pedestal 5, and are configured to swing up and down about a pivot point 7 as the rod of the cylinder device 6 moves back and forth. This is a rotating device A for the steel pipe p, which rotates the steel pipe p placed on the turning roller 1 and the free roller 4 at a fixed position.

Reference numeral 8 denotes a coating carriage which is located above the rotating device A and which is movable on a rail 9 provided in the axial direction of the steel pipe p. For example, it is manually moved to a predetermined position on the rail 9. After that, by rotating the handles 10 ₁ and 10 ₂ provided at the front and rear, the truck fixing lever 11 is pressed against the fixing plate 12 projecting inside each rail 9 to fix the painting truck 8 at a predetermined position. It is made like this.

Reference numeral 13 denotes, for example, three transfer rollers made of, for example, a sponge, which are arranged in series in the same direction as the axial direction of the steel pipe p with a predetermined interval, and 14 denotes the transfer roller installed outside the transfer roller 13. The diameter of the touch roller is slightly smaller than that of the transfer roller 13. The transfer roller 13 and the touch roller 14 are installed on the same shaft so as to be rotatable integrally.

Reference numeral 15 denotes a frame frame structure that is erected on the coating carriage 8. The frame frame frame 15 is used as a guide, and an elevating mechanism 16 including, for example, a handle 16a, a bevel gear 16b, and a screw shaft 16c is installed on the frame frame frame 15. An elevating stand 17 is provided which moves up and down via the. A cylinder device 18 is provided in a suspended manner on the elevating stand 17, and the transfer roller 13 and the touch roller 14 are attached to the rod end of the cylinder device 18 by a spring 19 urged downward. ..

Reference numeral 20 denotes a spray can attached to the lower end of the frame structure 15 in the same number as the transfer rollers 13 in a suspended manner. The tip of each spray can 20 has a nozzle hole. For example, a nylon tube 21 facing the outer peripheral surface of 13 is connected. Cylinder devices 22 are respectively arranged above the spray cans 20 so as to oppose each other, and when necessary, the rod is ejected to press the nozzle part of the spray cans 20 to spray the paint on the outer peripheral surface of the transfer roller 13. Has been done.

The marking device for the outer circumference of the steel pipe according to the present invention is constructed as described above, and the method of using the device will be described below.

First, the steel pipe p is placed on the turning roller 1 and the free roller 4 of the rotating device A by an appropriate means. At this time, the turning roller 1 and the free roller 4 are set to the optimum height according to the outer diameter of the steel pipe p to be marked.

Next, the coating carriage 8 is moved so that the transfer roller 13 is aligned with the axial position of the steel pipe p to be the marking strip, and the coating carriage 8 is fixed in position at that position. After that, the motor 2 of the rotating device A is rotated to rotate the steel pipe p via the turning roller 1.

Next, the rod of the cylinder device 18 is operated until the touch roller 14 contacts the steel pipe p and rotates. At this time, even if the pressing force of the touch roller 14 against the steel pipe p is large, the steel pipe p and the touch roller 14 are not damaged by the action of the spring 19. At this time, the vertical position relative to the frame structure 15 of the elevating frame 17 is optimally set according to the outer diameter of the steel pipe p to be marking.

As described above, the rods of the respective cylinder devices 22 are moved to the outer peripheral surfaces of the respective transfer rollers 13 that come into contact with the steel pipe p and rotate, thereby pressing the nozzles of the spray cans 20 to transfer the transfer rollers. The coating is applied to the outer surface of 13 and the required marking is applied to the outer peripheral surface of the steel pipe p that comes into contact with the coating.

After marking the outer peripheral surface of the steel pipe p in this way, the procedure opposite to the above is performed to wait for the next marking of the steel pipe p.

[0019]

[Effect of the device]

 As described above, according to the marking apparatus for the outer peripheral surface of the steel pipe according to the present invention, it is possible to perform a required marking on a predetermined position of the steel pipe irrespective of the outer diameter of the steel pipe to be marked. In addition, in the present invention, since the paint tank was abolished by using the spray can instead of the nozzle gun, it is only necessary to replace the spray can at the time of color change, and the nozzle gun and the paint tank can be washed and the paint can be mixed. It becomes unnecessary and the work time required for these can be shortened.
