Description

[Detailed description of the invention] This invention relates to a winding device for winding a plate material around a plate.

Rolled metal plates such as strip-shaped steel plates (hereinafter referred to as strips)
Equipment that continuously processes IJ ships (for example, in a fully continuous system), two winding machines (hereinafter referred to as coilers) for winding IJ ships are installed in series at the end of the line, and the two coils are used alternately. Continuous work is ensured by winding up the strip flowing through the inner and outer sides. Each coiler is equipped with an independent Bell I/Second winding device (hereinafter referred to as Bell I/Trapper), and the belt of the second belt wrapper presses the winding start end of the strip against the shaft of the coiler (hereinafter referred to as the mandrel). After winding, steady winding work begins by rotating the mandrel.

FIG. 1 is a front view schematically showing an example of a conventional coiler equipped with a belt wrapper as described above.

The illustrated device has N in the direction of travel of the strip 1 (arrow Z).
o Coiler 2 and No. Two coilers 2' are installed in series. At the rear of each coiler 2, 2' is a belt trapper 3 that can move back and forth in the strip traveling direction Z.
, 3' are installed.

In this figure, the tip of the strip 1 fed in by the pinch roll 4 is No. The state in which the coiler 1 is being wound around the mandrel 5 of the coiler 2 by the Bell J wrapper 3 is shown.

The belt wrapper 3 is mounted on a frame 7 with wheels 6, and is moved back and forth by horizontally moving the frame 7 with a sill 13 on a rail 14 laid on a base 12. Belt trapper 3 has four large and small rotatable 6-ra 89 supported on its axis, and a swingable roller 1.
A rubber belt 11 having a width corresponding to the width of the strip 1 is suspended from these five rollers 8, 9 and 10. When the belt wrapper 3 is advanced toward the mandrel 5 on the line 2 and the belt 11 is crimped onto the mandrel 5, a rotational driving force of the mandrel 5 (the driving device is not shown) is generated.
While the belt 11 rotates in synchronization with the mandrel 5, the tip of the strip 1 is guided by the belt between the swing blind roller 10 and the fixed four rollers 8 and wound around the outer peripheral surface of the mandrel 5. In this case, the swing roller 10 is pressed by a roller 16 of a pressing device 15 provided in front of the line 2, and is configured to reliably press and hold the belt 11 against the mandrel 5.

Next, when the strip 1 is wound in several layers around the outer circumference of the mandrel 5 and the required winding tension is secured, the pressing device 15
Then, the belt wrapper 3 is returned to the retracted position (indicated by chain lines in FIG. 1), and a steady winding operation is started.

In this way, when a predetermined amount of strip l is wound around the mandrel 5, the strip 1 is cut (the running shears for cutting are not shown), and the winding by the No. 1 coiler 2 is completed, and the subsequent The strip is wound up by the Nα2 coiler 2' according to the same procedure as described above. In this way, by alternately switching the No. 1 coiler 2 and the No. 2 coiler 2' for winding, it is possible to wind up continuously fed strips without stopping the line.

However, in such a winding device, it is necessary to attach an independent belt wrapper to each line, and these belt wrappers have extremely complicated structures and long machines, and the distance between the two lines is long. However, it has the disadvantage that equipment costs and construction costs are high.

In addition, in recent years, there has been a demand for faster strip winding to improve productivity, but with high-speed winding, the belt tends to meander, and the strip also meanders, resulting in belt damage and unwinding. This causes irregularities in the end faces of the coil, leading to deterioration in the quality of the coil. For this reason, there is a limit to the coiler winding speed, which has been an obstacle to improving productivity.

Furthermore, if a large rolling reduction ratio is applied in a cold rolling facility or the like, work hardening occurs in the strip, and it is necessary to apply a large pressure force to the belt when winding it around a coiler. For this reason, there is a problem in that the belt is easily damaged, shortens the belt's lifespan, and requires frequent replacement. In addition, for belt wrappers, thick materials and wide materials (e.g. approximately 4.5 + nm thick) are used.
.

In the case of a strip having a width of about 1,600 mm or more, a highly rigid structure is required, which has disadvantages such as being uneconomical in terms of equipment cost and maintenance cost.

The present invention proposes a rational winding device for a winder that can eliminate the conventional drawbacks as described above, thereby making it possible to shorten the installation interval between lines and increase the strip winding speed. Also, it is intended to increase the thickness of the sheet that can be wound.

The winding device of the present invention has a winding device for a winding machine in which a plurality of winding machines are arranged in series so as to alternately wind strips as described above. A wrapper frame is arranged, and each of the wrapper frames rotatably supports two winding U-rollers, and the wrapper frames are moved horizontally so that the winding rollers come into contact with and separate from the outer peripheral surface of the mandrel. The present invention is characterized in that a means for moving the strip is provided, and the strip is wound by the winding roller. As a means for horizontally moving the wrapper frame, a pneumatic cylinder or a hydraulic cylinder is usually used. Note that it is preferable to provide a device for spraying pressurized fluid such as compressed air from the wrapper frame toward the outer peripheral surface of the mandrel. This is so that the ends of the strip can be wrapped around the mandrel without sliding against the wrapper frame.

The details of the structure of the present invention will be explained below with reference to the embodiments shown in FIGS. 2 to 6. In these drawings, the same parts as in the conventional device are designated by the same reference numerals as in FIG. 1 above.

5.26.27 is rotatably connected to the rod end, and the side frames 16a, 17a, 18a.

Four guide rods 32 a and 32 b are arranged horizontally at the top and bottom of the back surface of 19 a and slideably pass through guide pushers 31 of the fixed frame 28 , 29 , 30 .
, 32c, respectively. Thus, the wrapper frame 16, 17, 18, 19 is connected to the cylinder 25.
26.27 allows it to move forward and backward in the horizontal direction. Here, the cylinder 25 installed between the two coilers 2 and 2' uses a double rod type cylinder as shown in the figure, and one rod end is attached to the wrapper frame 16 on the rear surface of the coiler 2. The rod end is N.

2 is connected to a wrapper frame 19 on the front side of the coiler 2'.

On the other hand, on the inner surface (mandrel side) of each wrapper frame 16, 17, 18, 19, there are guide plates 20a, 120b, 20c, 21 that form concentric arcs with the mandrel 5.5'.

On the outer surface of 21b, a plurality of substantially arc-shaped paddles 34 having a large number of nozzle tips 33 are arranged in parallel in the axial direction of the mandrel, and pressurized fluid (for example, 4 to 7 kg/kg) is supplied from the pressurized fluid supply port 36. compressed air) through the guide plate 20b,
A guide plate 20b from a large number of nozzle holes penetrated through 21b,
21b and the mandrel 5.5' or the winding strip 1.

Additionally, opposing wrapper frames 16, 17 and 18
．． The guide plates 20c and 21a at the bottom of the guide plate 19 are comb-shaped as shown in FIG. 5, and are removably engaged with each other so that the starting end of one roll of the strip can be smoothly introduced.

Furthermore, at the upper end of the wrapper frame 17.19 on the entry side of each mandrel 5.5', the spring lip 1 fed out from the pinch four 4.4' is smoothly introduced into the coiler 2.2'. An apron 35 is attached.

The winding device of the winder of the present invention is constructed as described above, and the procedure for winding a strip with a coiler using this device will be described below.

First, as shown in FIG.
Operate the trumpet frame 16 before and after the mandrel 5.
17 close to each other so as to wrap around the outer circumference of the mandrel 5,
The winding rollers 23a, 23b, 23c, and 23d are brought into light contact with the outer periphery of the mandrel 5 and rotated together with the mandrel 5. In this state, the wrapper frame 18, 19 for the N02 coiler 2' is at a position away from the mandrel 5' of the coiler 2' (indicated by the solid line in Figure 2), and its retraction limit is at the maximum diameter winding coil. 39 from the mandrel 5' for conveyance.

Next, the tip of the strip 1 is introduced into the mandrel 5 by the pinch roll 4, and when the tip is fed between the first winding roller 23a and the mantle 5, the rotational driving force of the mandrel 5 and the first winding The tip of the strip 1 moves forward in the direction of arrow Y due to the pressing force of the roller 23a, and is sent to the fourth winding roller 23d via the second winding roller 23b1 and the third winding roller 23c. The strip 1 that has passed through the first winding roller 23a is pressed along the outer peripheral surface of the mantle 5 by the pressurized fluid ejected from the guide plates 20b and 21b, and the strip 1 is pressed along the outer peripheral surface of the mantle 5, and the strip 1 is pressed along the outer peripheral surface of the mantle 5 by the pressurized fluid ejected from the guide plates 20b and 21b.
0 c, 21 a.

It can proceed smoothly without coming into sliding contact with the inner surfaces of 21b and 21c.

Thus, the tip of the strip 1 is attached to the fourth winding roller 23d.
It passes through and reaches the 5 mandrel side again, completing the winding of the first layer. After winding several layers in the same manner, when the required winding tension is sufficiently secured, the cylinder 2
5.26 The front and rear wrapper frames 16.17
The machine is moved back to release it from the winding position and begins regular winding work. In this case, the trumpet frame 17 on the front side of the mandrel 5 is moved horizontally to the retraction limit position (indicated by a chain line in FIG. 2), but the trumpet frame 16 on the rear side is stopped at an intermediate retraction position (not shown). After confirming that there is no coil on the mandrel 5' of No. 2 coiler 2' using, for example, a non-contact position detection type, move it to the rearward limit position (
(indicated by the chain line in Figure 2).

At this time, the winding rollers 24c and 24d of the wrapper frame 19 in front of the No. 2 coiler 2' move backward to a position where they lightly touch the mandrel 5' as in the case of the No. 1 coiler 2, and at the same time, the winding rollers 24c and 24d of the No. 2 coiler The wrapper frame 18 on the rear side is advanced by the syringe 27, and the winding roller 24a124b is brought into light contact with the outer periphery of the mandrel 5'.

Next (ζ, No, No.
, drive coiler 2' to prepare for winding of the subsequent strip. After the leading strip is cut and divided, the leading edge of the trailing strip is sent to the mandrel 5' via the Vinci roll 4' for the No. 2 coiler 2').
After winding is performed in the same manner as coiler 1 and coiler 2, regular winding work begins.

No. 1 The coil 39 that has been completely wound by the coiler is transferred from the mandrel 5 to a coil car (not shown) and sent to the next process according to a conventionally known procedure. No during this time,
2 coiler 2', the wrapper frame 18.19 completes the winding operation of the trailing strip tip, and the wrapper frame 18.19
The mandrel 5 and the S-attached rollers 23a and 23b are waiting to be moved back to the middle position until the coil 39 of the mandrel 5 is removed.
.

Push the wrapper frame 16 up to the position where 23c and 23d touch.
．． By horizontally moving the No. 1 coiler 17, the preparation for winding by the No. 1 coiler 2 can be completed again.

By repeating the above steps, the two coilers can alternately wind and wind the strip.
Therefore, it is possible to ensure continuous operation of the line.

As described above in detail, the winding device of the present invention uses a pair of wrapper frames with rotatable winding rollers on the front and rear sides of the mandrel of each coiler, instead of the belt of a conventional belt wrapper, so as to wrap around the outer periphery of the mandrel. Since they are installed horizontally movably, the structure is extremely simple. Moreover, in the above-mentioned embodiment, the wrapper frame on the rear side of the No. 1 coiler and the wrapper frame on the front side of the No. 2 coiler are configured to be horizontally movable integrally with one double-rod type sill. The total length can be significantly shortened. This B is clear by comparing and contrasting Figures 1 and 2. As described above, according to the present invention, the structure of the device can be simplified and the overall length can be shortened, making it possible to significantly reduce equipment costs and construction costs.

In addition, the winding operation at the starting end of the strip is performed using a rubberized winding roller and a pressurized fluid jet from the guide plate, so the winding operation is carried out smoothly without damaging the strip surface.
In addition to being able to reliably wrap the wrapper, the structure is more robust than that of a belt wrapper, making it possible to wrap thicker and wider strips than before.

Furthermore, the device of the invention is simple and robust in construction;
Winding speed can be increased compared to conventional equipment,
Eliminates the problem of meandering strips in belt wrappers.
It is possible to consistently wind the coil into a high-quality coil. Note that in the illustrated device, each winding roller is non-driven, but at least two of the four winding rollers for each coiler (preferably a first winding roller and a third winding roller) are driven. ) can be rotated faster than the circumferential speed of the mandrel using a morph or the like, thereby making it possible to wind at a higher speed than in the case of the non-driving method.

On the other hand, in the device of the present invention, the wrapping roller wears out during operation, but in that case, only the rubber lining portion needs to be repaired, so maintenance costs can be significantly reduced compared to the case of a belt wrapper.

In the device illustrated above, the wrapper frame on the rear side of the No. 1 coiler and the wrapper frame on the front side of the No. 2 coiler are simultaneously driven by double rod type cylinders, but these are driven separately using two independent single-rod type cylinders. Needless to say, it is also possible to drive the

Although the configuration of the present invention has been explained above using examples, the present invention is not limited only to these examples.
Various design modifications may be made without departing from the spirit of the invention.
