Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel strip winding device, and in particular, at the first stage of winding a steel strip around a reel drum, the tip of the steel strip is bent along the reel drum. The present invention relates to a steel strip winding device equipped with a guide mechanism.

[Conventional technology]

As a winding device for winding the seed steel strip around the reel drum for winding two to three times while smoothly bending the steel strip tip along the reel drum at the beginning of the winding, Simple jigs and belt wrapper devices are known.

As shown in FIG. 8 and FIG. 9, the above-mentioned jig secures both ends of the handles 3, 3 to a pair of left and right semi-circular steel plates 2, 2 equipped with a large number of rotatable roller bearings 1. , The left and right handles 3, 3 are connected with the flat bar 4,
The holding part 5 is attached to the upper part of the parts 3 and 3. The steel strip winding work using this jig is performed by two workers, and each worker holds the holding portion 5 while standing on the side of the left and right handles 3, 3 and holds the reel drum 6. Semi-circular steel plate around the upper half 2,
The inside of 2 is applied, the reel drum 6 is rotated little by little, and the tip end of the steel strip is wound while being curved along the outer circumference of the reel drum 6 by the roller bearing 1.
However, the winding of the steel strip using this jig is not preferable because the work itself is manual and inefficient, and there is a safety problem.

On the other hand, the belt wrapper device is configured as shown in FIGS. This device body 10
Has a guide wheel 11, and this guide wheel 11
By traveling along 12, the apparatus body 10 can be moved (about 2 m) to the reel drum 6 side. 14 is a cylinder for moving the device body 10, and its cylinder rod
The tip of 15 is connected to the bottom of the device body 10.

In the device body 10, an upper swing arm 16 and a lower swing arm 17 are supported by supporting shafts 18 and 19, respectively.The upper and lower swing arms 16 and 17 are rods 29 of respective cylinders 21 and 22. It is rotated by the expansion and contraction of 30.
Further, 23 is an endless belt, and the endless belt 23 is stretched around a tension roll 24, a hoist roll 25, and a swing roll 26. Reference numeral 27 is a cylinder for adjusting the tension of the endless belt 23, and the tension roll 24 is provided at the tip of the cylinder rod 28, and the endless belt 23 is hung on this.

Next, this action will be described.

During normal work (rolling work, steel strip on reel drum 6
(When 13 is wound), the device body 10 is installed at the standby position (position shown in FIG. 10), but when the new steel strip 13 is wound around the reel drum 6, the device body 10 is moved to the moving cylinder. It is moved to the reel drum 6 side by 14 (Fig. 11).

Next, the cylinder 22 is activated to move the lower swing arm 17
The tip of the upper swing arm 16 is moved downward by the cylinder 21 so that the endless belt is moved.
Wrap 23 around almost the entire circumference of reel drum 6. Also,
At this time, the cylinder 27 is operated to operate the endless belt.
It holds the tension of 23 properly.

Then, when the reel drum 6 starts to rotate, the endless belt 23 wound around the outer periphery of the reel drum 6 simultaneously rotates, and the tip of the steel strip 13 is guided by the belt portion supported by the tip of the lower swing arm 17 to form an endless belt. It enters between the belt 23 and the reel drum 6 and is wound around the reel drum 6.

When the steel strip 13 is wound around the reel drum 6 3 to 4 times, the cylinder 21 is actuated so that the upper swing arm 16 is lifted, the reel drum 6 is released from the endless belt 23, and then the cylinder 22 is actuated. By doing so, the lower swing arm 17 descends, and similarly the reel drum 6 is released from the endless belt 23. Finally, the apparatus main body 10 is retracted by the moving cylinder 14 and returns to the original standby position to complete the winding work process.

[Problems to be Solved by the Invention]

However, a large space is required to install the belt wrapper device. In addition, it is often the case that the space cannot be secured when installed in an existing device.
Further, there is a problem in that it is difficult to wind the tip of the steel strip 13 to which oil has adhered between the reel drum 6 and the endless belt 23.

The object of the present invention is to reduce the installation space of the device in order to solve the above-mentioned problems of the prior art, especially the unused space can be used, and the initial winding work can be performed easily, and it is difficult to rely on human power. An object is to provide a steel strip winding device that does not require work.

[Means for Solving the Problems]

The steel strip winding apparatus according to the present invention has a plurality of hoist rolls arranged in parallel with the reel drum in the vicinity of the lower outer periphery thereof, and guides the steel strip between each hoist roll and the reel drum. In addition, a steel strip winding device that winds this steel strip around the outer circumference of the reel drum as the reel drum rotates. And a first pressing member and a second pressing member are movably disposed at both ends in the circumferential direction of the semi-cylindrical body, and the first pressing member has a small diameter roll inside. , Connected to the semi-cylindrical body via a support shaft, and rotatably provided by a cylinder provided on the semi-cylindrical body side. Attach to one end of the moving arm, swing arm The other end freely weights roll contact and separation on the reel drum periphery provided on, wait roll the second
The pressing member has a weight that can rotate in the opening direction, the semi-cylindrical body is connected to a rod of a lifting cylinder provided on the traveling frame, and the traveling frame is provided so as to be horizontally movable at a predetermined height position. Characterized by the configuration.

[Action]

When the steel strip winding device is not in use, the semi-cylindrical body is pulled upward by the rod of the lifting cylinder, and the traveling frame is moved backward and stands by at a position diagonally above the reel drum. .

In use, the traveling frame moves forward, the semi-cylindrical body is positioned above the reel drum, and then the rod of the lifting cylinder is lowered. At this time, the first pressing member of the semi-cylindrical body is rotationally displaced in the opening direction by the cylinder, and the second pressing member at the other end is rotationally displaced in the outward opening direction by the weight of the weight roll. There is. Then, when the semi-cylindrical main body descends to a position in contact with the reel drum, the weight roll is lifted in contact with the outer periphery of the reel drum, and rotates the second pressing member in the closing direction via the swing arm.

After that, the steel strip is guided between the reel drum and the hoist roll, and its tip is applied to the inside of the first pressing member. next,
The cylinder is operated to rotate the first pressing member in the closing direction. After that, the steel strip is wound around the reel drum by rotating the reel drum. Steel strip is 3-4
Once wound, the rod of the cylinder is actuated in the contracting direction, thereby rotating the first pressing member in the opening direction.

Next, the lifting cylinder is actuated and the cylinder rod is contracted to lift the semi-cylindrical body away from the reel drum. At this time, as the semi-cylindrical body separates from the reel drum, the weight roll descends by its own weight, and the second pressing member automatically rotates in the opening direction. After the semi-cylindrical body is pulled upward, the traveling frame retracts in the horizontal direction, and the semi-cylindrical body waits at a waiting position diagonally above the reel drum.

The waiting place is not limited to the diagonally upper space, and may be a waiting place if it is not used.
