Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is arranged in parallel in the strip path line direction at a position corresponding to a side end surface of a strip.
The present invention relates to a strip-side end surface polishing apparatus that performs polishing in a row with a brush roll that rotates forward and a brush roll that rotates in a reverse direction around an axis parallel to the direction.

In this type of strip-side end surface polishing apparatus, the strip-side end slightly digs into the outer peripheral surface of the brush roll, so that the brush roll row polishes the side end surface of the strip and the brush rolls are rotated in opposite directions. One contributes to the polishing of the front side edge of the strip and the other contributes to the polishing of the back side edge. Further, since the acting force and the reaction force of the motions of the brush rolls having different rotation directions cancel each other out, the strip stably passes through the portion of the brush roll row.

2. Description of the Related Art The apparatus described above is already known as a deburring machine for strips (Japanese Patent Publication No. 61-490).
71). In this case, the table on which the strips are placed can be moved up and down in order to match the heights of the brush roll rows and the strips. As a result, the pressing direction of the brush roll row with respect to the strip is only horizontal, and the angle at which it acts does not change, and it is not possible to operate the brush roll more effectively for either the front or back edge. That is, the operating characteristic of the brush roll row is uniform. Further, in the brush roll row, each brush roll has the same width. In other words, each brush roll has the same action force of movement. For this reason, the three brush rolls cannot do this in order to balance the acting force and the reaction force of the movement in the entire row of brush rolls.

[0004]

DISCLOSURE OF THE INVENTION The object of the present invention is to make a row of brush rolls capable of more effectively polishing an arbitrary portion in the area of the front surface side edge-side end surface-back surface side edge of the strip. This is to develop a type strip side edge polishing machine.

Further, the present invention is to develop a strip-side end face polishing apparatus of the above-mentioned type capable of balancing the acting force and the reaction force of motion as a whole brush roll row by using a minimum of three brush rolls. Is an issue.

[0006]

In order to solve the above-mentioned problems, the present invention is arranged in parallel with the strip path line direction at a position corresponding to the side end surface of the strip, and is normally rotated in a direction around an axis parallel to the direction. In a strip-side end face polishing device that performs polishing with a row of brush rolls and a brush roll that rotates in the opposite direction, a frame that allows angular displacement and vertical displacement in the vertical direction in the strip width direction by an adjustment mechanism is placed at a fixed position. , A row of the brush rolls on the frame, a first brush roll and a multiple thereof occupy both sides thereof, and both sides are combined to have the same width as the brush roll, It is characterized by being equipped with a 1/2 width brush roll.

[0007]

The present invention will now be described with reference to the drawings showing an embodiment of the present invention.

In the figure, reference numeral 1 denotes a brush roll, and the brush roll 1 is arranged at a position corresponding to a side end surface of the strip P and is formed by a plurality of rows arranged in parallel in the pass line direction of the strip P. This brush roll row is a row of brush rolls that normally rotate around an axis parallel to the pass line direction and brush rolls that rotate in the opposite direction.

Reference numeral 2 denotes a gantry, and the gantry 2 is arranged at a fixed position on both the left and right sides of the strip P, and the adjustment mechanism 3 causes angular displacement and vertical displacement back and forth within the vertical plane of the strip P in the left-right direction, that is, the width direction. It is supposed to be done. The adjusting mechanism 3 is based on a wedge-shaped adjusting member 32 driven by a hydraulic jack 31, and may be installed at the end on the strip P side and the end on the opposite side of the pedestal 2. The adjustment mechanism 3 is preferably of a fine adjustment type in order to make it possible to finely perform angular displacement and vertical displacement of the gantry 2. The format shown is an example.

The first brush roll 1A is mounted on the mount 2.
And a roll row that occupies both sides of this roll and that is adjacent to both sides and has the same width as the roll, and has a half width on one side of the second brush roll 1B. It is equipped as a row of brush rolls 1. In the illustrated format, one second brush roll 1B is arranged on each side of the first brush roll 1A, but a plurality of second brush rolls 1B may be arranged.

In the first brush roll 1A, the roll on the right side in FIG. 2 is left via the transmission mechanism 7 by the one shaft 6 of the double-headed shafts of the reversing device 5 driven by the motor 4 which are rotated in opposite directions. The left side is rotated clockwise. The second brush rolls 1B and 1B have the other shaft 8 of the double-headed shaft,
The right roll in FIG. 2 is rotated clockwise and the left roll is rotated counterclockwise through the transmission mechanism 9. The first brush roll 1A is attached to the hollow rotary shaft, and the second brush roll 1B,
1B is attached to a common rotary shaft, and the hollow of the rotary shaft of the first brush roll 1A is attached to the second brush rolls 1B and 1B.
The rotation axis of is penetrated.

When the pedestal 2 is vertically displaced and the row of the brush rolls 1 is positioned at a height directly facing the end on the strip P side, the press contact angle of the row of brush rolls with respect to the end surface on the strip P side is 90 degrees, that is, its action. The property is horizontal orientation. In this case, the row of brush rolls serves to more effectively polish the strip end surface.

When the pedestal 2 is angularly displaced in a vertical plane in the width direction of the strip P, the angular displacement in which the end on the side opposite to the strip P rises, the direction of pressure contact of the row of the brush rolls 1 with respect to the strip P, that is, the action characteristic direction. Is inclined low from the center of the brush roll to the strip top surface side edge. In this embodiment, the polishing of the row of brush rolls is more effective for the top edge of the strip.

When the angular displacement of the gantry 2 is opposite to the above, the direction of the action characteristics of the brush roll row is also inverted from the lower side to the upper side, and the brush roll row operates more effectively with respect to the strip lower surface side edge. To do.

In the present invention, the row of the brush rolls 1 occupies both sides of the brush roll 1A, and the adjacent ones are combined to have the same width as the roll 1A. The fact that the rolls 1B are used means that they rotate in mutually opposite directions, and at the minimum, three brush rolls balance the acting force and the reaction force of the movement as a whole of the brush roll row. Bring

[0016]

According to the present invention, in order to perform the above-mentioned operation, the brush roll row is provided, and the surface side edge of the strip-the side end surface-
It is possible to more effectively polish any part of the area on the back side edge, and by using a minimum of three brush rolls, it is possible to balance the action force and reaction force of motion as a whole brush roll row. The task of developing a strip-side edge-polishing device of the type mentioned at the outset that is possible is achieved.
