The present invention relates to a device for disassembling and assembling a segment of a reel rotatably mounted to a reel driving unit, and more particularly, to safely disassemble and assemble a plurality of segments mounted on the circumference of the reel at once to reduce equipment downtime. Segment replacement device of the reel to reduce the operation accident.

1 illustrates the operation of replacing segments of a conventional reel.

In general, the reel 1 is mounted to the reel driving unit 8 so as to be rotatable and to move forward and backward. Usually the reel (1) is for winding the strip after the heat treatment process, it is rotated by the rotational driving force of the drive device in the reel driver 8 is wound around the reel (1). In addition, the reel (1) after winding the strip to the desired amount to form a coil is moved forward or backward by the drive device in the reel driving unit 8 is separated from the coil strip center, the coil strip is finished winding After that, the process of winding the new strip is repeated.

At this time, the reel 1 may be heat-deformed by the thermal properties of the strip while the outer circumferential surface in contact with the strip while winding the strip after the heat treatment process, the outer circumferential surface may be damaged by the strip having an uneven shape have.

If the outer circumferential surface of the reel 1 is damaged as described above, the inner surface of the strip may be damaged by the damaged outer circumferential surface of the reel 1 during the winding operation of another strip. Therefore, the reel 1 must always maintain a flat and even outer circumferential surface.

In general, a plurality of segments 2 are mounted on the outer circumferential surface of the reel 1 to perform the winding of the strip, and when the segments 2 are damaged by many strip winding operations, the segments 2 are removed. After disassembly from the reel 1, replacement with new segments 2 ensures that a good coil strip is always formed.

In order to mount the segments 2 on the outer circumferential surface, the reel 1 has a plurality of triangular wedges 6 inclined in the direction of the reel driving part 8 on the outer circumferential surface, the segments 2 ) Is mounted on the reel 1 by forming a plurality of grooves formed on its inner surface so as to fit well with the plurality of triangular wedges 6. The inner surfaces of the wedges 6 and the segments 2 are combined to some extent so as not to be separated from each other by gravity, and detailed descriptions and drawings thereof will be omitted.

A jig 5 or various coupling elements (not shown) may be used to securely secure the segments 2 on the reel 1.

Conventionally, in order to replace the segments 2 of the reel 1, as shown in Figure 1, each of the segments 2 using a transport device such as a crane and two chain blocks (3). The segment 2 was disassembled while lifting upward while pushing the operator at the side edge of the segment 2 with the lever 4. After the one segment 2 is separated, the reel 1 is rotated in the circumferential direction so that the non-separated segment 2 is directed upward, and then again the chain block 3 and the lever 4 as described above. Separation of the segment (2) was performed using.

However, in the conventional segment 2 removal operation, after separating the segments 2 one by one from the reel 1, new segments must be assembled one by one on the outer circumferential surface of the reel 1, and thus the reel Since disassembling and assembling the segments 2 from (1) takes a lot of time, there has been a problem in that the work efficiency is significantly reduced as a whole because the winding of the strip is not performed.

In addition, since the conventional disassembly and assembly work of the segment 2 is not possible in the narrow place, the work using the lever 4 is not possible, and the operation of directly manipulating the lever 4 is required, so that the disassembly of the segment 2 is performed. And there is a problem that the worker is exposed to the risk of safety accidents during assembly work.

The present invention is to solve the conventional problems as described above, to provide a segment replacement device of the reel to reduce the downtime and reduce the operation accident by disassembling and assembling a plurality of segments mounted on the circumference of the reel at once Its purpose is to.

In addition, the inclined guide portion 11b is formed on the fixed tapered blocks 11.

The guide groove 13a of the coupling taper blocks 13 is formed to engage with the guide portion 11b of the fixed taper blocks 11.

Referring to FIG. 6, an annular rotating body 14 is rotatably coupled to a side surface of the annular ring 12 located farther from the reel driving part 8 of the annular rings 10 and 12. . That is, the guide protrusion 12a formed along the inner diameter of the annular ring 12 and the guide groove 14c formed to fit the guide protrusion 12a on the side of the rotating body 14 are fastened to each other. Since the guide protrusion 12a and the guide groove 14c are surface-machined to be rotatable with respect to each other, the rotor 14 is rotatably coupled to the annular ring 12.

The rotating body 14 forms a rack gear 14a on a circumferential side opposite to the surface coupled to the side surface of the annular ring 12, and a female screw portion 14b is formed at the center thereof.

In addition, the annular ring 12 is coupled to the outer ring through a fastening mechanism such as a protective ring 15 and a screw having a long rectangular hole 15a formed in the circumference thereof. The protection ring 15 wraps and protects the rotor 14 to prevent the rotor 14 from being separated, and the hole 15a is a spur gear that meshes with the rack gear 14a which will be described later. It is formed to insert (17).

A male thread portion 16a is provided on only one circumferential surface on each side of the fixed tapered blocks 11 mounted on the outer circumferential surface of the segment 2 toward the farther side from the reel driving portion 8 of the fixed tapered blocks 11. A circular rod 16 is formed.

Hereinafter, the operation of the reel segment replacement device 100 according to the present invention.

The embodiment of the reel segment replacement apparatus 100 according to the present invention was applied to disassemble and assemble four segments 2 mounted on the outer circumferential surface of the reel 1 as shown in FIG. 1.

Referring to FIG. 2, the reel segment replacement device 100 according to the present invention is caught and moved upward by a transfer device such as a crane caught by two chain blocks 3, and the segment replacement device 100 is illustrated in FIG. 2. And conveyed until placed in the position shown in FIG. 4A and 4B, the segment replacement apparatus 100 may include a male screw portion 16a of the rotary body 14 and a male screw portion 16a formed at each of the four circular rods 16. Start screwing, the rotating spur gear 17 meshes with the rack gear 14a of the rotating body 14, and the coupling taper blocks 13 are fitted with the fixed taper blocks 11; Is placed in the starting position. At this time, looking at Figure 4b in more detail, the female threaded portion (14b) of the rotating body 14 is coupled to the four screws 16a and the screw thread is not coupled all but a little over. At this time, the stopper 19 mounted on the side of the annular ring 10 is in contact with the wall surface of the reel driving unit 18.

When the preparation for disassembly of the segments 2 on the reel 1 is completed as described above, the various coupling elements in which the segments 2 are firmly fixed to the reels 1 are dismantled. At this time, the segments 2 are coupled to the wedges 6 mounted on the reel 1 to some extent so that they are not separated or separated from the reel 1.

After setting the initial setting position as described above, when the worker rotates the handle knob 26, the handle 25 and the shaft 24 integral with the handle 25 are rotated. Accordingly, the spur gear 17 integral with the shaft 24 is rotated, and the rack gear of the rotating body 14 engaged with the spur gear 17 in accordance with the rotation of the spur gear 17. 14a) is rotated, and the rotating body 14 is rotatably mounted on the side of the fixed annular ring 12, so that the rotating body 14 naturally rotates according to the rotation of the rack gear 14a. .

When the rotor 14 is rotated, the female threaded portion 14a of the rotary body 14 is screwed with the male threaded portions 16a formed on the four circular rods 16. The whole 14 tries to proceed in the wall direction of the reel driving part 8 along the threaded teeth of the four male threaded portions 16a, and the male threaded portions 16a are opposite to the traveling direction of the rotating body 14. I will try to proceed.

However, since the stopper 19 is already abutted against the wall surface of the reel driving unit 8, the movement to rotate in the wall direction of the reel driving unit 8 of the rotating body 14 is performed by the stopper 19. Is prevented from being moved by the male screw 16a from the wall surface of the reel driving part 8 toward the handle 25 so that the male screw 16a is integrally formed with the circular rod 16 on which the male screws 16a are formed. The fixed taper blocks 11 and the segments 2 forming the movement to move away from the wall surface of the reel driving unit 8 is generated.

That is, the reel segment replacement device 100 except for the fixed taper blocks 11 has a movement to move toward the reel driving part 8 as the operator rotates the handle 25, but the stopper ( 19 stops without moving toward the wall surface of the reel driving unit 8, on the contrary, fixed taper blocks 11 mounted on the circumferential surface of the segments 2 are connected to the tapered blocks 13; The guide groove 13b is moved upward in the right direction (see FIG. 3), and the segments 2 are moved upward in the right direction deviating from the wedges 6 of the reel 1.

In this case, the fixed taper blocks 11 can move upwards as well as in the right direction along the guide grooves 13b of the coupling taper blocks 13, as shown in FIG. 4B. This is because the threading of the male threaded portions 16a formed on the circular rods 16 is not completely engaged with the threaded portion of the female threaded portion 14b of the rotating body 14 until the teeth of both teeth are fully engaged. The fixed taper blocks 11 are movable upward along the guide grooves 13b of the coupling taper blocks 13.

As a result, as the fixing taper blocks 11 move upward, the screw threads of the male screw portions 16a formed on the circular rods 16 are screwed to the female screw portion 14a of the rotating body 14. Screw and rotate to the right, engaging deeper than the first one.

The segments 2 and the fixed taper blocks 11 are moved upwards in the right direction until the threads of the female threaded portions 14a of the rotating body 14 are completely engaged with the threads of the male threaded portions 16a. The segments 2 are then completely disengaged from the reel 1.

Thereafter, the segment replacement apparatus 100 is moved to completely deviate from the circumference of the reel 1 using the chain blocks 3, and the separated segments 2 are fixed taper blocks 11. It is completely disassembled by unscrewing the screws 31, which are the connecting media with).

After disassembling the segments 2, new segments 2 are again joined to the fixed taper blocks 11 by screws 31, and in the reverse order of disassembly of the segments 2 described above. New segments are thus mounted on the circumferential surface of the reel 1.

According to such a series of actions, the heat-deformed or surface-damaged segments 2 are safely disassembled and reassembled from the reel 1.

According to the reel segment replacement apparatus according to the present invention as described above, by disassembling and assembling a plurality of segments mounted on the circumference of the reel at once, it is possible to obtain a cost reduction and productivity improvement effect of reducing downtime of the equipment, The effect of preventing safety accidents and operation accidents in advance can be obtained.

While the invention has been shown and described with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit or scope of the invention as set forth in the claims below. I would like to know that those who have knowledge of Easily know.
