Preferably, the supporting member 11 is provided in the lateral direction of the first conveyor 10. The support member 11 is provided with the support cylinder (11a of FIG. 4), and the rotation part 11b rotated by the support cylinder 11a. When the pipe bundle 5 is moved by the first conveyor 10 to contact the stopper member 16, the support cylinder 11a expands to rotate the pivoting portion 11b. The support member 11 supports the pipe bundle 5 at the rear. Although the square pipe 1 is shown in the figure, in the case of a circular pipe, the support member 11 supports the pipe to prevent the circular pipe from rolling backward.

The second conveyor 15 moves the pipe 1 separated by one layer by the height adjusting unit 20 and the horizontal moving cylinder 29 to the pipe moving unit 30.

The height adjusting unit 20 includes a lifting member 22 that is lifted and lowered by a driving force transmitted from the lifting motor 21. The driving force of the elevating motor 21 is transmitted to the elevating member 22 by the pinion gear 23 and the rack gear 24.

The horizontal movement cylinder 29 is installed on the support frame 29a and selectively stretches to move the pipes 1 of the uppermost layer of the pipe bundles 5 to the second conveyor 15. The expansion and contraction of the horizontal movement cylinder 29 is guided by the guide bar 29b.

The side surface of the movable member 31 and the side surface of the fixing member 32 are provided to be spaced apart by a predetermined interval, preferably the width or diameter of the pipe 1. Accordingly, the pipe 1 moved by the second conveyor 15 is loaded on the shank-dong member 31 and at the same time stopped by the fixing member 32, and the stopped pipe 1 is shank-dong member 31. When is raised, the upper and lower surfaces of the movable member 31 and the fixing member 32 are downwardly inclined surfaces 31b and 32a, and are moved downward along the downwardly inclined surface 32a of the fixing member 32 to rotate the rotating member 37. Is loaded on. Preferably, the side surface 32b of the fixing member 32 is formed to be inclined. This is so that the pipe 1 can be easily moved from the moving member 31 to the fixing member 32.

The figure shows that two grooves 32c and 32d are formed in the fixing member 32. Therefore, when the movable member 31 is raised and lowered twice, one pipe 1 can be loaded in each of the grooves 32c and 32d. That is, the pipe 1 is loaded in the first groove 32c by the first ascent, and the pipe 1 of the first groove 32c is moved to the second groove 32d by the second ascent. The new pipe 1 is moved to the first groove 32c. An appropriate number of grooves 32c and 32d of the fixing member 32 may be formed in consideration of the diameter or width of the pipe 1.

Preferably, the case 63 may be adjusted in height. Rotating the pinion gear (63a) installed under the case 63, the rack gear (63b) is rotated to adjust the height of the case (63).

The painting unit 70 is installed at the rear of the heating unit 60 to spray paint onto the heated pipe 1. As shown in FIGS. 13 and 14, the painting unit 70 includes a paint booth 71 having an inlet 71a and an outlet formed therein, a door 71b installed therein, and a sealed interior space 71c. A nozzle 72 installed in the space 71c for spraying paint, an exhaust portion 73 for discharging air and paint components in the internal space 71c to the outside, and a rear pipe of the paint booth 71 A canopy hood 74 for discharging the dried paint component from (1) to the outside is provided.

The exhaust portion 73 discharges the purified air to the outside by allowing the air and the paint component of the internal space 71c to pass through a scrubber. A scrubber is a device for treating air containing harmful fine substances, and is commonly used.

Meanwhile, as shown in FIG. 15, the pipe 1 via the canopy hood 74 is continuously dried while being moved by the conveying roller part 40, and then the third conveyor is lifted by the lift part 35 ′. It is moved to 80.

The lift part 35 'has the same structure as the lift part (35 in FIGS. 6 and 7) provided between the second conveyor 15 and the transfer roller part 40.

As shown in FIGS. 16 and 17, the third conveyor 80 moves the pipe 1 moved by the lift part 35 ′ to the stacking unit 90, and the fourth conveyor 85 is stacked. The pipe bundle 5 made in the unit 90 is discharged to a pipe bundle packaging device (not shown) or the like.

The stacking unit 90 is installed between the third and fourth conveyors 80 and 85. The stacking portion 90 includes a support member 95 provided so as to be continuous to the end of the third conveyor 80, and a stacking member that is selectively moved up and down by the shank east motor 91a behind the support member 95 ( 91, a support plate 92 provided at the rear end of the stacking member 91 and selectively rotated by the rotating cylinder 92a, and a pipe moved to the support member 95 by the third conveyor 80. The sensor (not shown) which detects the number of (1) and the loading cylinder 93 which pushes and moves the pipe 1 mounted in the support member 95 to the loading member 91 are provided.

When the number of pipes 1 moved to the support member 95 by the third conveyor 80 reaches a predetermined number, a sensor (not shown) detects this and transmits a signal to the controller (not shown), and the controller is for loading. The cylinder 93 is inflated to move the pipes 1 on the support member 95 to the loading member 91. When the pipes 1 are moved to the loading member 91, the loading member 91 is lowered by a predetermined distance by the shank-dong motor 91a. Subsequently, when the number of pipes 1 moved to the support member 95 by the third conveyor 80 reaches a predetermined number, the loading cylinder 93 expands and the pipes 1 are stacked on the loading member 91. Move to. The support plate 92 allows the pipe 1 to be moved to the loading member 91 to be aligned in a line.

The pipe bundle 5 is formed by repeatedly stacking the pipes 1 by the above process. When the pipe bundle 5 is completed, the rotating cylinder 92a is contracted so that the support flat plate 92 rotates backward. When the support plate 92 is rotated backward, the pipe bundle 5 moves to the fourth conveyor ( 85).
