Description

TECHNICAL FIELD The present invention relates to a steel plate pressing roll device that is provided in a steel plate winding device and presses a steel plate.

[Prior Art] In general, a steel plate wound by a steel plate winding device is likely to cause a winding deviation at a winding tail end where tension is not applied. And the winding shape (shape) of the steel plate is
It collapses due to the deviation of the winding tail end. Therefore, the steel plate winding device is provided with a steel plate pressing roll device for pressing the winding tail end of the steel plate, thereby preventing the slippage.

For example, in a one-mandrel shaft type tension reel device which is a type of steel plate winding device, as shown in FIG. 3, a tension reel device 20 and a steel plate pressing roll device 21 are integrally provided, and a steel plate pressing roll is provided. The device 21 is supported on the tension reel device 20. In such a steel plate winding device, in order to accurately wind the steel plate 22, it is necessary to align the side end portions 22a, 22a of the steel plate 22 to be wound. Therefore, the tension reel device 20, that is, the mandrel shaft 23 that winds the steel plate 22 is movable in the axial direction according to the meandering direction of the steel plate 22 to be wound. Therefore, the steel plate
When the tension reel device 20 is moved in the axial direction of the mandrel shaft 23 during the winding operation of the roll 22, the snubber roll 24 of the steel plate pressing roll device 21 is simultaneously moved in the same direction. Thereby, the winding operation of the steel plate 22 is performed without any problem.

On the other hand, recently, as a new type of steel plate winding device,
The two-axis carousel reel device 1 shown in the figure is being widely used. In this carousel reel device 1, the mandrel shaft 3 is provided on the revolution plate 5, the mandrel shaft 3 itself rotates, and the steel plate 2 is wound while revolving along with the rotation of the revolution plate 5. It is a thing. Therefore, the steel plate pressing roll device 7 is configured to be installed on a fixed object other than the carousel reel device 1.

However, in the above conventional structure, the steel plate pressing roll device 7
Is provided separately from the carousel reel device 1, and the position of the snubber roll 8 of the steel plate pressing roll device 7 is fixed. Therefore, in order to move the steel plate pressing roll device 7 following the movement of the mandrel shaft 3 of the carousel reel device 1, it is necessary to separately provide an expensive and complicated tuning mechanism. That is, in the above-described conventional structure, unless the tuning mechanism is provided, an abnormal relative force acts between the fixed snubber roll 8 and the mandrel shaft 3 of the carousel reel device 1 that moves in the axial direction, so that the steel plate Wrinkles and scratches occur on the winding surface of No. 2. Furthermore, the snubber roll 8 is also damaged. In order to prevent such an inconvenience, it is necessary to provide the above-mentioned tuning mechanism, so that there is a drawback that the cost of the steel plate pressing roll device is increased and the structure is complicated.
