[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding device.

[0002]

2. Description of the Related Art As shown in FIG. 4, in a conventional hot rolling equipment, a strip 2 rolled by a rolling mill 1 is conveyed downstream in a line direction 5 by a hot run table 4 in which a number of table rollers 3 are arranged. Then, it is passed through a winding machine entrance side pinch roll 6, tensioned by the winding machine entrance side pinch roll 6, the direction is changed, and then wound by a winding machine 7 such as a down coiler. It has become.

[0005] As shown in FIG. 5, the upper and lower surfaces of the strip 2 coming out of the winding machine entrance side pinch roll 6 are guided between the winding machine entrance side pinch roll 6 and the winding machine 7. An upper guide 8 and a lower guide 9 are provided for leading to the winder 7, and the upper guide 8 is an upstream upper fixed guide 10
The upper fixed upper guide 10 is divided into an outer diameter when the coil 12 formed by winding the strip 2 has a maximum diameter and a lower pinch of the winding-side input pinch roll 6. It is fixed at a position above a common tangent line connecting the rollers 13, and the downstream upper movable guide 11 can swing vertically about the downstream end of the upstream upper fixed guide 10.

In addition, 14 is an upper pinch roller of the pinch roll 6 on the winding machine entrance side, 15 is a mandrel of the winder 7, and 16 is a wrapper roll that presses the strip 2 so that the mandrel 15 can wind the strip 2 without loosening. Reference numeral 17 denotes a wrapper roll arm for retracting the wrapper roll 16 as the coil 12 becomes thicker, and reference numeral 18 denotes an interval between the downstream end of the upstream upper fixed guide 10 and the lower guide 9.

The leading end of the strip 2 coming out of the pinch roll 6 on the winding machine entrance side is connected to an upper guide 8 and a lower guide 9.
In this case, the downstream upper movable guide 11 is tilted downward in advance as shown by the imaginary line in FIG. 5, so that the upstream upper fixed guide 10 and the downstream upper movable guide 11 While changing the direction of the tip of the winder 7 to the mandrel of the winder 7.

The end of the strip 2 is a mandrel 15
After a few turns, the downstream upper movable guide 11 is retracted by tilting the downstream upper movable guide 11 upward as shown by the solid line in FIG.

[0007]

However, the above-mentioned conventional winding equipment has the following problems.

That is, when the strip 2 to be wound is a thick material, the upstream side upper fixed guide 1 is provided so that the strip 2 can be easily passed through because the strip 2 has a large passing resistance.
Although the distance between the downstream end of the lower guide 9 and the lower guide 9 is increased, when the strip 2 is thin, the strip 2 loses rigidity and is easily affected by wind pressure. Since the tip of the strip 2 passing between the upper guide 8 and the lower guide 9 cannot be prevented from being turned up or bent by wind pressure, there is a problem that it is difficult to wind the strip around the mandrel.

The present invention has been made in view of the above circumstances, and has as its object to provide a winding device capable of guiding a thin or thick strip to a winding machine without any problem.

[0010]

SUMMARY OF THE INVENTION The present invention is directed to a winding machine in which the upper and lower surfaces of a strip coming out of the winding-side input pinch roll are guided between the winding-machine input side pinch roll and the winding machine. An upper guide and a lower guide are provided to guide the upper guide, and the upper guide can be moved up and down together with an upstream upper movable guide that can swing vertically about the upstream end thereof, and a downstream end of the upstream upper movable guide. having an upstream end, and, in which according to the take-up winding facility, characterized in that configured in the vertical direction to swingably downstream side upper movable guide around the lower upstream end.

[0011]

The operation of the present invention is as follows.

[0012] The upper and lower guides provided between the winder inlet pinch roll and the winder guide the upper and lower surfaces of the strip coming out of the winder inlet pinch roll to the winder. It is led.

The upper upper movable guide of the upper guide is vertically swingable about its upstream end, thereby increasing the distance between the downstream end of the upper upper movable guide and the lower guide. In the case where the strip is thick, the gap is widened to reduce the passing resistance of the strip, and when the strip is thin, the gap is narrowed. To prevent the tip of the strip from being turned up or bent by wind pressure.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 show an embodiment of the present invention.

In the drawing, 2 is a strip, 9 is a lower guide, 13 is a lower pinch roller of the pinch roll 6 on the winding machine entrance side, 14 is an upper pinch roller of the pinch roll 6 on the winding machine entrance side, and 15 is a winding roller. Mandrel of machine 7, 16 is mandrel 1
5 is a wrapper roll that presses the strip 2 so that the strip 2 can be wound up without loosening, 17 is a wrapper roll arm that retreats the wrapper roll 16 as the coil 12 becomes thicker, and 18 is an upstream upper fixed guide 1
0 is the distance between the downstream end and the lower guide 9.

An upstream upper movable guide 19 and a downstream upper movable guide 20 for guiding the upper surface of the strip 2 are provided between the winder inlet pinch roll 6 and the winder 7.

Then, when the strip 2 is thick, the resistance at the time of passage is reduced by moving the upstream upper movable guide 19 upward as shown by a solid line in FIG. When 2 is a thin object, it can be tilted downward as shown by a virtual line in FIG.

The lower end of the upstream upper movable guide 19 and the upper end of the downstream upper movable guide 20 are connected to the bracket 2.
1. Connected to the center of rotation 23 of the wrapper roll arm 17 of the winder 7 via the arm 22 so as to be able to move up and down by expansion and contraction of a driving device 24 such as a cylinder connected to the bracket 21, and , Downstream upper movable guide 20
The lower end of the wrapper roll arm 1 via the arm 25
7 and the strip 2 as shown in FIG.
2 can be tilted downward with the wrapper roll arm 17 as the coil 12 becomes thicker as shown in FIG.

Next, the operation will be described.

The leading end of the strip 2 coming out of the winding machine input side pinch roll 6 is guided by the upper guide 8 and the lower guide 9, and the upstream upper movable guide 19 and the downstream upper movable guide 20 direct the distal end of the strip 2. The process of guiding the mandrel of the winder 7 while making changes is shown in FIG.
Since it is the same as FIG. 5, the description is omitted.

In the present invention, when the strip 2 is thick, as shown by the solid line in FIG.
4, the lower end of the upstream upper movable guide 19 and the upper end of the downstream upper movable guide 20 are raised via the bracket 21 and the arm 22, and the wrapper roll 16 contacts the mandrel 15. By contacting,
The downstream end of the downstream upper movable guide 20 attached to the wrapper roll arm 17 via the arm 25 is tilted downward.

By doing so, the gap 18 between the downstream end of the upstream upper movable guide 19 and the lower guide 9 can be increased, so that the passing resistance of the thick strip 2 can be reduced. It becomes possible.

The downstream upper movable guide 20 is gradually retracted upward together with the wrapper roll 16 which is retracted by the wrapper roll arm 17 in accordance with the winding of the coil 12, as shown in FIG.

When the strip 2 is thin,
As shown in FIG. 3, a drive device 24 such as a cylinder is extended and moved, and the lower end of the upstream upper movable guide 19 and the downstream upper movable guide 20 are moved through the bracket 21 and the arm 22.
Lower the upper end of the wrapper roll 1
The downstream end of the downstream upper movable guide 20 attached to the wrapper roll arm 17 via the arm 25 is tilted downward by bringing the 6 into contact with the mandrel 15.

In this manner, the gap 18 between the downstream end of the upper movable guide 19 on the upstream side and the lower guide 9 can be narrowed, so that the tip of the thin rigid strip 2 is turned up by wind pressure. It can be prevented from being bent or bent.

Here, since the thin strip 2 has low rigidity, the passing resistance does not matter even if the interval 18 is reduced.

The present invention is not limited to the above-described embodiment, and the upstream upper movable guide 19 may be moved up and down by a drive device different from the downstream upper movable guide 20. Of course, various changes can be made without departing from the spirit of the present invention.
