delete

The pipe holder 60 is a block member 61 rotatably coupled to the rotating shaft 42, as shown in Figures 4 to 6, and in the axial direction of the rotating shaft 42 on one side of the block member 61 It includes a holding member 62 coupled to rotate to secure the pipe (P) seated on the pedestal 46 with the pedestal 46.

On one side of the block member 61, the bracket 63 is fixedly installed as shown in FIG. 5, and the pivot bar 65 is rotatably coupled to the hinge shaft 64 at the tip of the bracket 63. The holding member 62 is coupled to the tip of the rotation bar 65.

In addition, the holding member 62 is coupled to the front end of the rotation bar 65 to have a predetermined play so that the impact is relieved when it is in close contact with the outer surface of the pipe (P).

Meanwhile, one side of the block member 61 is hinged to the rod 66a of the holding cylinder 66 whose rear end is hinged to the frame 41 so that the block member 61 is predetermined around the rotation shaft 42. It is rotated at an angle.

And one side of the block member 61 is equipped with a rotating cylinder 67 for rotating the holding member 62 so as not to interfere with the pipe (P) to be transported, the rod of the rotating cylinder 67 ( 67a) is hinged to the lower side of the rotation bar 65 so that the rotation bar 65 is rotated in the direction of the rotation axis 42 about the hinge axis (64).

In the pipe drying apparatus according to the present invention configured as described above, when one or two pipes transferred from a bundle of pipes bundled into a plurality of pieces in the whole process are introduced into a conveying line such as a conveyor belt, water is sprayed from the washing apparatus, and washing is performed. Then, the hot air is applied in the drying apparatus to dry the surface of the pipe, and when the paint is injected into the booth of the coating apparatus, paint is sprayed onto the surface of the pipe to achieve painting.

Subsequently, when the pipe P having a color on the surface is transferred and supplied to the conveying unit 20 of the pipe drying apparatus according to the present invention, the pipe P is discharged to the discharge unit 30 after being naturally dried while being raised and lowered by the drying unit 40. Will be.

First, when one pipe (P) or a pair of pipes (P), which have been painted in the coating booth of the previous process, are transferred to the transfer unit 20, the horizontal transfer member 23 transferred according to the driving of the transfer motor 21. Pipe (P) is located on the upper side of the pedestal 46 positioned between the, while the rotary motor 48 is operated to transfer the lifting conveying member 45 of the drying means 40 by a predetermined distance. The pipe P seated on the horizontal conveying member 23 is seated on the pedestal 46.

That is, the rotational force according to the operation of the rotary motor 48 is transmitted to the drive sprocket 48a and the electric sprocket 49 through the chain 50. Accordingly, when the rotary shaft 42 rotates, the upper sprocket 43a ( The lower sprockets 44a, 44b, 44c, 44d are also rotated by a predetermined angle by the lifting and lowering conveying member 45 by the rotation of the lifting and lowering conveying member (43b) 43c and 43d by a predetermined angle. Pedestal 46 coupled to the outside of the 45 is moved upward by one pitch.

Therefore, as the pedestal 46 moves, the pipe P seated on the horizontal conveying member 23 of the conveying part 20 is seated on the pedestal 46 and rises by one pitch, and then to the conveying part 20. The pipe P to be supplied is also mounted on the pedestal 46 in the same manner to rise by one pitch.

At this time, the pipe (P) conveyed to the upper side as shown in Figure 4 before the base 46 is switched from the horizontal direction to the vertical direction, the pipe holder 60 is operated at a position of about 45 ° so that the pedestal 46 In the holding state of the pipe (P) seated in the) will be transferred in the opposite direction.

That is, when the pedestal 46 reaches a position of about 45 ° with respect to the rotating shaft 42 while rotating clockwise by the operation of the lifting conveying member 45, the holding cylinder of the pipe holder 60 ( 66 is operated to reverse the rod 66a so that the block member 61 rotates counterclockwise about the rotational shaft 42 to rotate the holding member 62. One side is in close contact with the outer surface of the pipe (P) seated on the pedestal 46, that is, the surface of the opposite side pipe (P) of the pedestal 46 to hold the pipe (P).

In this case, the holding member 62 is coupled to the front end of the rotating plate 65 by a pin with a predetermined clearance so that the holding member 62 is held in close contact with the opposite side of the pedestal 46 without impact and is held so that the pipe P does not flow. In the center direction, the pipe P is not moved toward the center side by the guide plate 47.

Subsequently, the elevating conveying member 45 conveyed by the operation of the rotary motor 48 is conveyed to the opposite side of the pitch in the conveying direction so that the vertical line and the pedestal 46 form an angle of about 45 °, wherein the holding member 62 ) Is moved at the same speed as the pedestal 46 by the operation of the rod 66a, which is advanced in accordance with the operation of the holding cylinder 66.

When the pedestal 46 and the holding member 62 are transported to the opposite side while holding the pipe P, the holding cylinder 66 is operated again to rotate the holding member 62 clockwise. After the pipe P is seated on the contact surface of the holding member 62 and rotated, the pipe P is seated on the next pedestal 46.

At this time, the pipe (P) is seated on the rear side, not the upper surface of the pedestal (46).

And when the pipe (P) is seated on the back side of the pedestal 46, the rotating cylinder 67 is reversed the rod (67a) to hold the holding member 62 and the rotating bar 65 around the hinge shaft (64) Positioning so as to rotate in one 90 ° direction is not generated interference with the pipe (P).

Subsequently, the rotation bar 65 and the holding member 62 rotated in one direction rotate the block member 61 counterclockwise again by the reverse operation of the rod 66a of the holding cylinder 66, and then again rotate the rotation cylinder ( When the rod 67a of the 67 is advanced, the holding member 62 and the rotating plate 65 are positioned in line with the bracket 63. At this time, the rod 66a of the holding cylinder 66 is counterclockwise. As shown in FIG. 4, the holding member 62 holds the pipe P seated on the pedestal 46.

Since the jaw portion 46a is formed in the pedestal 46, the plurality of pipes P can be transported, as well as a large diameter P can be held and transported, thereby making the work more stable and a transfer speed. Is further improved.

In this way, the pipe P seated on the pedestal 46 transported by one pitch by the operation of the elevating conveying member 45 ascends from the frame 41 and is then dried to dry at room temperature.

The pipe P, which is dried while being transported from the support 46 of the elevating transport member 45, is seated at the discharge part 30 when the support 46 is moved downward, and then transported by a separate transport means. The packaging is made.

The present invention as described above is not limited to the above-described specific embodiments, and any person having ordinary skill in the art to which the present invention pertains may make various changes without departing from the gist of the present invention as claimed in the claims. will be.

Therefore, according to the present invention, the pipe is made on the surface of the pipe is raised by one pitch and then descending to dry it is possible to obtain a high-quality coating quality, the portion that is in contact with the outer surface of the pipe during transportation is minimized stains, etc. Is prevented from occurring, thereby improving the coating quality of the pipe.
