Description

TOP-DOWN RECOILER OF PIPE}

The present invention relates to a top-down recoiler of a pipe, and more particularly, to a top-down recoiler of a pipe that can easily produce a coiled pipe product using the weight of the pipe.

Since pipes and wire rods are thin and long, they are usually wound in coils and delivered in a reduced volume. Therefore, in actual use, it can be expanded to a predetermined shape and cut and used.

To this end, conventionally, a guide roller is installed around a cylindrical rotating drum, and a rotational production is made by introducing a pipe.

As shown in FIGS. 1 to 3, the top-down recoiler of the pipe according to the present invention has a fixed frame (F) in which the pipe introduction part (800) is formed, and horizontal rotation with respect to the fixed frame (F). The main drum 100 installed as possible, the guide rollers 200a, 200b, and 200c provided along the circumferential direction of the main drum 100, and a tension unit provided to face the circumference of the main drum 100 ( 300, a pipe descending guide 400 for guiding the pipe from the tension unit 300 downwardly in a spiral manner, and a pipe coil disposed under the main drum 100 to temporarily receive the descending pipe coil. The accommodating part 700 is comprised.

Here, the main drum 100 is installed in the fixed frame (F) via a vertical axis (S) that can be rotated. In addition, the main drum 100 is rotationally driven by the motor M and the worm gear W fixed to the fixed frame F.

In addition, the guide rollers 200a, 200b, and 200c are disposed at the first position of the first guide roller 200a which is first met when the pipe P is advanced, and the second guide roller 200b which is arranged next. And a third guide roller 200c. If three or more arrangement | positioning places of the said guide roller are OK.

In the present embodiment, the first guide roller 200a is formed with a roller 200a-1 for guiding the first introduced pipe and a roller 200a-2 for guiding the rotational movement at the same time. The rotation guide roller (200a-2) guides only until the pipe rotates two times around the rotating drum (100).

Here, the guide roller (200c) is the last of the guide roller 200a, 200b, 200c of the guide roller 200c, so that the tip of the pipe is naturally guided to the pipe descending guide 400, from the lower end of the main drum 100 It is preferable that the height h is set.

On the other hand, the tension unit 300 is installed to face the circumference of the main drum 100 is installed to prevent the pipe (P) to proceed outward.

Specifically, as shown in FIG. 6, the tension unit 300 includes a connection member 320, a first actuator 330 and tires 340 respectively provided at both ends of the connection member 320. It is. Accordingly, as the first actuator 330 expands and contracts, the tire 340 is in close contact with or separated from the main drum 100.

The tension unit 300 may provide a hinge point at the middle portion of the connection member 320 to compress or separate the tire 340 from the main drum 100 in the form of a lever.

In addition, the main drum 100 and the tire 340 are coupled via a speed reduction device 900. Specifically, the vertical axis of the main drum 100 and the reduction device 900 are coupled via the belt 360, the output shaft of the reduction device 900 and the rotation axis of the tire 340 is interposed through the gear 370. Are combined. To this end, pulleys 920 and 120 are respectively provided on the vertical shafts of the reduction apparatus 900 and the rotating drum 100. At this time, the circumferential speed of the tire 340 is set larger than the circumferential speed of the main drum 100 (for example, 1: 5). Accordingly, the pipe P is bent while rotating the movement is made more smoothly.

And, in front of the tension unit 300 in the rotational direction of the main drum, a pipe lowering guide 400 for guiding the pipe downward along the spiral path is provided. It is sufficient that only a part is installed from the main drum 100 to the pipe coil accommodating part 700 described later.

The pipe coil receiver 700 is composed of a pipe coil carrier 710 having a cylindrical circumference, and is preferably carried by a conveyor or a lifting device when the pipe coil carrier 710 is wound by a predetermined amount. The upper end of the pipe coil carrier 710 is formed to have a partial conical shape so that it can be wound smoothly without being initially caught.

On the other hand, as shown in Figure 1 and 7, the cutting unit 500 is provided in the front of the rotation direction around the main drum 100. Specifically, the cutting unit 500, the cutting unit 500 is composed of two cutters 510 and 510 rotating in opposite directions to each other, so that the pipe is cut when the two cutters are closest It is. Here, the cutter 510 is configured in the form of an elongate arm, and a cutter blade is formed at the tip of the arm. The motor M is coupled to one of the cutters 510, and is interlocked through the gears G1, G2, and G3. When cutting, the cutter 510 needs to rotate only once.

A guide guide 570 is provided between the two cutters 510 and 510 before and after.

Furthermore, since the fourth guide roller 550 is fixedly installed adjacent to the cutting unit 500, the cutting operation is made easier. Here, it can be detected by the length measuring sensor (not shown) that the pipe (P) is a predetermined length is wound separately.

In addition, for the continuous supply of the pipe (P), the lower portion of the main drum 100, there is provided a temporary pipe support 600 that can be folded in accordance with the operation signal of the cutting unit 500. As shown in FIG. 2, once the pipe of the length set by the cutting unit 500 is cut, the remaining pipe which is cut off is wound on the pipe coil carrier 710 of the pipe coil receiver 700, and then immediately supplied. One end of the pipe is temporarily accommodated in the temporary pipe support 600. Of course, when the pipe product of the pipe coil receiver 700 is transferred to another place, the temporary pipe support 600 is operated in reverse again so that the coil is wound around the pipe coil carrier 710.

Specifically, as shown in FIGS. 1 to 3, the temporary pipe support part 600 includes a vertical movement shaft MS installed on the vertical axis S to enable longitudinal movement, and the vertical movement shaft ( MS) and the shelf member 610 is hinged over the fixed frame (F). Since the vertical movement shaft (MS) is connected to the shelf member 610 as a link over the fixed frame (F), when the vertical movement shaft (MS) rises, the shelf member (610) is raised to prevent the pipe from being caught. As it descends, it unfolds, so it is possible to temporarily hold the pipe.

Meanwhile, as shown in FIGS. 9 and 10, the pipe coil accommodating part 700 rotates the pipe coil carrier 710 having a cylindrical circumference and horizontally while supporting the pipe coil carrier 710 from below. The upper turntable 720 may be configured. In this configuration, when the pipe is wound around the pipe coil carrier 710, the pipes can be prevented from being twisted or overlapped.

Furthermore, the upper turntable 720 is rotatably disposed with respect to the lower turntable 730 in a state in which two of the upper turntables face each other, and the lower turntable 730 is capable of horizontal rotation with respect to the fixed frame F again. It is preferable to be installed. In order for the upper turntable 720 and the lower turntable 730 to rotate, a motor M and a worm W are installed.

In this configuration, the upper turntable 720 rotates itself to allow the pipe to be smoothly wound on the pipe coil carrier 710, and the pipe coil carrier 710 and the empty pipe completely wound by rotating the lower turntable 730. The coil carrier can be replaced.

Hereinafter, the operation of the top-down recoiler of the pipe according to the present invention.

First, the pipe (P) to be wound is introduced while being guided through the fixed frame (F) in which the pipe introduction portion (800) is formed.

The pipe P starts to be wound on the rotating drum 100 after passing through the first guide roller 200a.

Then, the traveling pipe passes through the second guide roller 200b and enters the tension unit 300. The tension unit 300 strongly adheres the pipe to the rotating drum 100, and smoothly deflects the pipe.

By repeating this operation three times around the rotating drum 100, the bending deformation of the pipe is stably maintained. However, it is not necessary to strictly limit the number of windings on the rotating drum.

After the third winding repetition, the tip of the pipe P passes through the third guide roller 200c in the vicinity of the tension unit 200 and immediately passes through the fourth guide roller 550. This is because the height of the third guide roller 200c is set to a predetermined value (see FIG. 8).

Next, the tip of the pipe descends along the pipe descending guide 400.

Then, the pipe which is lowered is wound around the pipe coil carrier 710 installed at the lower portion.

Thereafter, the pipe is continuously wound along the circumference of the pipe coil carrier 710.

When the pipe length (usually 1000 m) measured by the length measuring sensor (not shown) installed in the pipe introduction part 800 or the like reaches a predetermined value, a signal is transmitted and the cutting unit 500 operates. Accordingly, the pipe is cut to a predetermined length.

After cutting, the temporary pipe support 600 is operated and deployed horizontally, so that subsequent pipes can be seated.

In the meantime, the lower turntable is rotated 180 ° horizontally so that the empty pipe coil carrier 710 is located directly below the rotating drum 100.

Next, the temporary pipe support 600 operates in reverse to wind the temporarily received pipe into a new pipe coil carrier 710.

In addition, the fully wound pipe coil carrier 710 is lifted and shipped to the pipe coil product.

Through this series of operations, the pipes are produced continuously without interruption.

According to the present invention of the configuration as described above, the pipe can be wound horizontally while descending, there is no deformation, and the component for accommodating the coil is simplified.

In addition, since the tension circumferential speed of the outer portion of the pipe advances faster than that of the inner portion, the tension unit allows smooth and sufficient bending deformation to be applied to the pipe.

Moreover, even if a pipe is cut | disconnected to predetermined length, since productivity can be wound continuously without stopping operation, productivity is high.
