Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brush roll machine for reciprocating left and right brush rolls, and more particularly to a brush roll machine for reciprocating left and right brush rolls for brushing a metal strip path line running in the length direction such as polishing. .

The brushing of a metal strip pass line by a brush roll machine is to make it efficient. For this reason, when the brushing process proceeds to the end region of the metal strip, the end of a new metal strip is welded to the end of the strip. The actual situation is that they are connected with each other and are made in the form of continuous pass lines. The metal strips to be welded are often of different widths.

Thus, it is desired that the brush roll of the brush roll machine used for brushing the metal strip pass line has a required length depending on the plate width of the pass line.

[0004]

2. Description of the Related Art Conventionally, in order to adapt a brush roll to a difference in plate width of a metal strip pass line, in the case of conversion wider than a fox, a short brush roll used until then is replaced with a long brush roll, When converting from wide to fox, the fact is that long brush rolls were used as they were, "like both large and small". According to such a method , the plate width conversion from wide to ridge has an unfavorable result. That is, longer brush roll than the plate width, wear in the form of a region protruding beyond the sides of the strip pass line remains without <br/> wear, advances, the use of not too long period, from the present day It becomes unusable for wide strips, effectively degrading the brushing ability to be short. In general, brush rolls for brushing metal strip pass lines are at most 60
The length is about 0 mm, and it is not inexpensive including the water cooling system and the like accompanying it.

In order to prevent such uneven wear of the brush roll, a brush roll machine for reciprocating the brush roll with respect to the support stand of the brush roll while reciprocating in the width direction of the metal strip path line, that is, left and right, has already been proposed. Has been done. However, since this prior art ones, left and right reciprocation of the brush roll is a constant stroke,
This presents a problem in dealing with metal strip pass lines of different widths. Since the metal strip pass line normally has a wide variety of plate widths in the range of 600 to 1800 mm, it is necessary to set the left and right strokes of the brush roll to a large extent so as to accommodate the plate width. Moreover, the intended intention cannot be achieved unless the left and right strokes of the brush roll are large enough to meet the meandering of the metal strip pass line. As a result, in order to reciprocate the brush roll of about 600 mm at the shortest stroke left and right, it is necessary to use a considerably large reciprocating mechanism, and the equipment cost reduces the brush roll cost.
Increase as ultra-El.

[0009]

The present invention will now be described with reference to the accompanying drawings which show embodiments of the present invention.

In the drawing, 1 is a brush roll stand, and the brush roll stand 1 is a metal strip pass line P.
Is provided at a fixed position and is movable in the width direction of the strip path line P. Reference numeral 3 is a guide rail for guiding the movement of the brush roll stand 1, and 4 is a linear bearing of the stand. The brush roll 2 is rotated by the motor 5.

The brush roll stand 1 is reciprocated in a predetermined direction by a driving machine 6. More specifically, the stand 1 includes a feed screw 7 connected to the driving machine 6, a ball screw 8 screwed to the feed screw 7, a carriage 9 including the ball screw 8, a mount 10 connected to the carriage 9, and The driving machine 6 reciprocates in a predetermined direction through the stand / frame connecting frame 11. As the drive unit 6, a geared servo motor capable of shifting can be advantageously applied.

The metal strip pass line P advances to a position of the brush roll 2 of the brush roll stand 1. A first detector D1 and a second detector D2 are arranged on the entrance side of the brush roll 2 symmetrically with respect to the vertical center line of the metal strip pass line P traveling in the location of the brush roll 2. The first detector D1 detects one side edge of the metal strip pass line P and the second detector D2 detects the other side edge of the same pass line. First and second detector D
1 and D2 spread in the plate width direction as shown by the diagonal lines in FIG.
Has a certain visual field or detectability. As the detectors D1 and D2, a television camera, a photoelectric switch, an optical sensor, a magnetic sensor, a sonic sensor, or the like can be used.

A third detector D3 for detecting the position of the brush roll stand 1 that is being moved Ri by the drive machine 6 is provided. Third detector D3 may be advantageously applied to the transformer de Yusa. The third detector D3 is connected to a drive system for the brush roll stand 1, for example, the feed screw 7, and operates at the operation amount of the drive machine 6, that is, the movement amount of the brush roll stand 1 by the drive machine 6, to the brush roll stand 1. detecting the moved while a location of the stand 1. like this
The position of the brush roll stand that is moving.
According to the specification that detects by the moving amount, the brush roll stand
While moving 1, move position in real time
It can be detected, and based on the detected movement position,
Based on the left-right relational position of the board
The brush roll stand 1 to the width of the board and the meandering of the board.
Precise control of reciprocating motion with corresponding stroke
Bring to do.

The output sides of the first, second and third detectors D1, D2 and D3 are connected to the input side of a sequence controller 12 which controls the operation of the driving machine 6.

While the brush roll 2 brushes the metal strip pass line P traveling in the position of the brush roll 2, the brush roll stand 1 is reciprocated in the width (left and right) direction of the pass line by the driving machine 6. .

During the brushing process of the metal strip pass line P, the first detector D1 detects one (left) side edge of the pass line P and the second detector D2 the other (right) side. The edge is detected, and the third detector D3 detects the movement amount, that is, the movement position of the brush roll stand 1 by the driving machine 6. The plate edge detection signal of the metal strip pass line P of the first and second detectors D1 and D2 and the moving position detection signal of the brush roll stand 1 or the brush roll 2 of the third detector D3 are sent to the sequence controller 12. Is entered.

When the drive roll 6 moves the brush roll stand 1 leftward (or rightward) by a predetermined distance, the first and second detectors D1 and D2 detect the plate edge and the third detection. Based on the detection of the moving position of the brush roll stand 1 by the device D3, the sequence controller 12 controls the operation of the driving machine 6 so that the moving direction of the brush roll stand 1 is reversed. The details are as follows.

During the above-mentioned movement of the brush roll stand 1, the displacement thereof is detected by the third detector D3, and the first,
Two detectors D1 and D2 detect the plate edge of the metal strip pass line P.

Assuming that the right end of the brush roll 2 is to the left of the right end of the metal strip pass line P and the brush roll 1 is moving to the right, the left end of the plate by the first detector D1 at that time. When the detection value of the plate width detection value from the left end to the center side fixed position and the detection of the rightward movement position of the brush roll stand 1 by the third detector D3 coincide with each other, the brush roll 2 is substantially It is the time when the left end of the metal strip pass line P meets the left end of the metal strip pass line P. At this point, an inversion signal is input from the sequence controller 12 to the drive unit 6, the drive unit 6 is inverted, and the brush roll stand 1 is switched to move to the left.

During the leftward movement, the detection of the leftward movement position of the brush roll stand 1 by the third detector D3 is the second detection.
The right end of the brush strip 2 and the right end of the metal strip pass line P substantially meet when the right and left position of the right end of the plate by the detector D2, that is, the detected value of the plate width from the right end to the fixed position on the center side, coincides. It is the time when at this point,
An inversion signal is input to the driving machine 6 from the sequence control device 12, and the driving machine 6 is converted into an operation for driving the brush roll stand 1 to the right.

That is, the brush roll stand according to the present invention.
Drive unit 6 detects the first and second detectors D1 and D2.
Based on the left and right position of the captured strip,
Of the brush roll stand 1 detected by the detector D3 of No. 3
Based on the moving position, the brush roll stand 1
The amount of operation is controlled so that the stroke makes the required reciprocating motion.
It is done. In this way, the stroke of the brush roll stand 1 or the brush roll 2 is automatically regulated according to the plate width and the lateral meandering of the metal strip pass line to be brushed.

The width of movement of the brush roll stand 1, that is, the brush roll 2 to the left and right is regulated on the basis of the left and right relational positions of the edges of the plate as described above. Therefore, by using, as the brush roll 2 of the brush roll stand 1, those having an appropriately long dimension with respect to the plate width, and by reciprocating the brush roll left and right during brushing,
In order to prevent the above-described uneven wear of the brush roll, a stroke corresponding to the brush roll 2 protruding outward from a plate edge by a relatively short distance of, for example, about 150 mm,
It is sufficient to reciprocate the brush roll stand 1 from side to side. Therefore, the drive system such as the drive unit 6 may be small and small. Moreover, the lateral stroke regulation of the brush roll stand 1 deals with the plate width, and automatically follows the lateral meander of the plate progress.

The detectors D1, D2 of the first and second also corresponds the welds of different metal strips mutually the plate width, to work <br/> movement.

The difference in plate width between the front and rear plates of the welded part is considerably different from the variation in plate width of the metal strip itself having the same width and the degree of lateral meandering of the plate progress. Therefore, the welding location can be detected in the plate width detection by the first and second detectors D1 and D2 of the plate which is advancing. The detection of the welded portion may be useful for separating the brush roll 2 from the metal strip pass line when the welded portion passes through the portion of the brush roll 2. Welding points do not require brushing. The brush roll 2 can be separated from the strip pass line by a means known per se.

Usually, the range of the width of the metal strip is 60.
It is 0 to 1800 mm. In the present invention, in order to make the brush roll correspond to the plate width range, it is sufficient to prepare several types of brush rolls having different lengths. The brush rolls having different lengths may be properly used and replaced according to the plate width in the following manner.

A carriage 13 which is movable in the direction of the length of the metal strip path line P is installed on the side of the brush roll stand 1 opposite to the motor 5, and a brush roll 2 of different required length is installed on the carriage 13. 1, 2-2 ... 2-n are installed. (FIG. 7) On the other hand, two brush roll machines A according to the present invention are installed side by side in the length direction of the metal strip pass line P. Furthermore,
A brush roll machine B having a brush roll having a length corresponding to the largest plate width is provided as a spare machine in parallel with the brush roll machine of the present invention (FIGS. 6 and 7). The brush roll machine B does not need to reciprocate the brush roll left and right.

When replacing the brush rolls with those having different lengths, the brush roll machine B is kept in the operating state.
Further, one of the two brush roll machines A continues to operate. For the other, the first and second detectors D1, D
Based on the detection of the front shown plate width by 2, to stop the and rotation away from the metal strip are becoming row run the brush roll, drawn from the brush roll stand 1 to the motor 5 and the opposite side of the outer side, dolly dent The brush roll of the required length on 13 is put, and this new brush roll is pressed against the metal strip pass line to perform the brushing operation. Next, with respect to the brush roll machine A which has continued to operate, the replacement of the brush roll and the operation of a new brush roll are performed as described above. When replacing the brush roll,
If necessary, so that the required brush roll on the dolly 13 is opposed to the brush roll stand 1 in the required brush roll machine A, carriage 13 is allowed I position if. The brush roll can be separated from the metal strip pass line, the brush roll can be pulled out of the system, a new brush roll can be set, and its operation can be performed in accordance with a method known per se.

After replacing the brush roll, the brush roll machine B is used.
Pulls the brush roll away from the metal strip pass line.

The metal strip pass line may have a warp referred to as C-warp that is curved in the width direction of the plate. When the C warp passes through the first and second detectors D1 and D2, the first and second detectors D1 and D2 detect it as a change in plate width. It is preferable to perform the plate width detection by the first and second detectors D1 and D2 under the condition that the warp is corrected.

When the brush roll has a stroke that extends beyond the plate end and the brush roll is reciprocated left and right on the plate surface during brushing, the area of the brush roll that strokes beyond the plate end is the pressure contact of the brush roll with the plate. Since it is squeezed at the bottom and edge of the plate, the condition of wear is different from other regions. When the speed of the left-right reciprocating motion of the brush roll 2 with respect to the stand 1 is high, the brush roll 2 is worn and dented more in the end region or near the end, and when it is slow, the regions other than the end are worn more. Dent.

In order to deal with this uneven wear, the speed of the left and right reciprocation of the brush roll 2 attached to the stand 1 by the drive machine 6 is changed according to the wear of the brush roll 2 by filling the drive machine 6 with a variable speed type. Is preferably determined accordingly. The degree of wear of the brush roll 2 can be judged by the naked eye.
