Description

[0001]
[Industrial application fields]
The present invention relates to a side polishing apparatus for a metal strip such as a steel plate, a plated steel plate, etc., and as a mode, generally, a brush of a peripheral surface polishing operation type arranged with an axis inclined with respect to its pass line at the metal strip side end. The present invention relates to a metal strip side edge polishing apparatus that performs polishing with a roll.
[0002]
In the present specification, the term “polishing” in the present invention is used as a collective term for “grinding and polishing”. This is the same throughout the specification.
[0003]
In the present specification, the “plated steel sheet” refers to a plated steel sheet.
[0004]
The metal strip side end polishing apparatus of the above-described type has a function of polishing the side end surface of the strip and polishing either the front or back edge of the strip side end depending on the rotation direction of the brush roll. This means that in order to polish the front and back edges of the strip side end, it is necessary to use two types of brush rolls having different rotation directions.
[0005]
[Prior art]
Previously known as the metal strip side edge polishing device of the previous style, the brush rolls with different rotation directions are independent to give the device the polishing ability of the end surface and front and back edges of the strip side end. That is, two brush roll machines including the roll are provided in the front-rear direction of the strip pass line. The brush roll has a normal cylindrical peripheral surface. Such conventional techniques have the following problems.
[0006]
Although the brush roll is pressed against the side edge of the strip, the polishing of the front and back area around the side edge of the strip did not work effectively, and the front and back surfaces were plated and excessive plating adhered to the side edge. It is not suitable for side edge polishing of a plate, for example, polishing of galvanizing excessively adhering to the side edge of a hot dip galvanized steel sheet. In such a plate, it is often desired to polish not only the side end surface and the front and back edges of the side end, but also the front and back regions around the side end.
[0007]
In order to perform polishing on the strip side edge with an independent structure type brush roll, a backup roll is required, and it is physically impossible to actually back up the end of the plate with the roll. Bending occurs and good polishing cannot be obtained.
[0008]
In practice, the strip-side edge polishing brush roll needs to detect the position of the plate end and be displaced to follow the plate in the width direction of the plate, and one brush roll machine for that purpose is inherently relatively expensive. Is in reality. In view of this point, it is a problem that there are a plurality of brush roll machines as described above.
[0009]
[Problems to be solved by the invention]
An object of the present invention is to succeed in the following in polishing a metal strip side end such as a steel plate or a plated steel plate in the above-described manner.
[0010]
The same brush roll serves to polish the front, back and side edges around the side edge of the strip by selecting the direction of rotation, and mainly the front, back area and front and back edges around the side edge of the strip. Also works to polish the part.
[0011]
The strip side edges are polished well without the need for a backup roll, and a very good polish is applied to the thin strips.
[0012]
The metal strip side edge polishing apparatus according to the present invention includes two or more rows arranged on each side from the center of the row to the end, and the metal strip side ends are arranged close to each other in a direction inclined with respect to the pass line of the strip. A brush roll of a peripheral surface polishing operation type (a type in which the peripheral surface performs a polishing operation) that rotates in the opposite direction between adjacent ones is disposed at a required position for polishing the strip side end, and the brush roll As a whole, the parallel body by the integration is characterized in that its peripheral surface is a concave curved surface.
[0013]
In order to obtain the desired polishing effect, four brush rolls that are arranged in a predetermined parallel in the predetermined mode and perform a predetermined rotation are generally sufficient to be arranged in four.
[0014]
【Example】
The present invention will be described with reference to the drawings illustrating exemplary embodiments of the present invention.
[0015]
The peripheral surface polishing-type brush roll that polishes the strip S side end at the side end of the metal strip S, such as a steel plate, a plated steel plate, and the like is included in the figure. Reference numeral 1 is assigned.
[0016]
A plurality of brush rolls 1 are arranged on each side from the center to the end of the row, and in parallel with the strip S side end in parallel with the strip S side end in a direction inclined with respect to the pass line P of the strip. It is arranged at the required location for polishing the edges. As shown in FIG. 1, the arrangement can be performed by mounting the brush roll 1 on the inclined shaft 3 supported on the bases 4 and 4 fixed on the base 2 in the manner shown above. The tilt shaft 3 is a fixed type. The brush roll 1 is rotatable on the shaft 3.
[0017]
The number of brush rolls 1 arranged in parallel is not necessarily limited as long as it is a predetermined plurality as shown above, but in general, a plurality of brush rolls 1 in parallel are arranged in parallel with four brush rolls. To two addresses per side. The illustrated one is a set of four brush rolls.
[0018]
Each of the plurality of brush rolls can be filled with a similar one to a known brush roll for polishing the strip surface, for example, a plurality of disk-type brush roll elements 1a stacked and bound.
[0019]
The parallel brush rolls 1 are configured to rotate in opposite directions between adjacent ones. Specifically, each brush roll has a wheel shape including a hub and a rim that is substantially integral with the hub, and the outer brush rolls 1-1 and 1-4 are rotatable on the rotating sleeves 6 and 7 on the shaft 3, respectively. The sleeve 6 and the hub 1-2h of the inner brush roll 1-2 are connected, and the sleeve 7 and the hub 1-3h of the inner brush roll 1-3 are connected. The pulley 8 is connected to the sleeve 6, and the pulley 9 is connected to the sleeve 7. The pulley 10 is connected to the hub 1-1h of the brush roll 1-1, the pulley 11 is connected to the hub 1-4h of the brush roll 1-4, and the brush roll 1-1 is connected to the brush roll 1-4 by the pulley 10. The pulley 11 is rotated in a predetermined direction by the pulley 11, the brush roll 1-2 is rotated by the pulley 8 through the sleeve 6, and the brush roll 1-3 is rotated by the pulley 9 through the sleeve 7 in the predetermined direction. The pulley 10 for the brush roll 1-1 is driven by the motor M1 through the transmission mechanisms 13 and 14 and the intermediate shaft 17 connecting these mechanisms. The pulley 8 for the brush roll 1-2 is driven by the motor M2. 16. Driven through the intermediate shaft 5 connecting these mechanisms, the pulley 9 for the brush roll 1-3 is driven by the motor M1 through the transmission mechanism 13, the intermediate shaft 19 extending from the intermediate shaft 17, and the transmission mechanism 20. The pulley 11 for the brush roll 1-4 is driven by the motor M2 through the transmission mechanism 15, the intermediate shaft 18 extending from the intermediate shaft 5, and the transmission mechanism 21 (see FIG. 4). Each of the transmission mechanisms may be a toothed belt or a chain sprocket type. Since this type of transmission mechanism does not cause slipping, the polishing results described later of the brush rolls 1-1, 1-2, 1-3, and 1-4 are stabilized.
[0020]
In the figure, the coupling between the sleeve 6 and the pulley 8, the coupling between the sleeve 7 and the pulley 9 is performed by a key k-stop, the coupling between the hub 1-1h and the pulley 10, and the coupling between the hub 1-4h and the pulley 11 is performed by a bolt b-stop. The hubs 1-1h, 1-2h, 1-3h, 1-4h and the rims 1-1r, 1-2r, 1-3r, 1-4r of each brush roll are the same as the connection between the hub and the rim in the automobile wheel. Are combined in various forms. Reference numerals 1b and 1n are attached to the bolts and nuts. The connection between the sleeve 6 and the hub 1-2h and the connection between the sleeve 7 and the hub 1-3h are made by bolts 6b and 7b.
[0021]
5 is shown in FIG. 5. In FIG. 5, only one bolt and nut are shown for each connection pair for the sake of simplifying the illustration.
[0022]

A motor M2 for driving the pulley 8 of the brush roll 1-2 and the pulley 9 of the brush roll 1-3 is also provided with a reversible rotation type, and the brush rolls 1-2 and 2 are switched by forward / reverse switching of the rotation of the motor M2. The rotation of 1-3 is also a normal or reverse selection.
[0023]
The parallel body obtained by integrating the brush rolls 1 has a concave surface as a whole as shown in FIG.
[0024]
The parallel body of the brush rolls 1 is disposed on both sides of the pass line P under the above-described predetermined mode on the front side of the brush roll R1 that polishes the plate surface of the strip S on the strip pass line P. Generally, the arrangement may be between the ringer roll R2 adjacent to the entry side of the brush roll R1 and the ringer roll R3 on the near side thereof. The brush roll parallel bodies on both sides of the pass line P have the same inclination direction and angle.
[0025]
Each of the parallel bodies formed by the integration of the brush rolls 1 on both sides of the strip pass line P is abutted with an appropriate pressure on the end of the strip S of the pass line P according to a conventional method, and is driven as described above. Polish the side edges.
[0026]
During this polishing, one of the brush roll parallel bodies on both sides of the strip automatically follows the position in the plate width direction by following a method known per se (not shown) when the strip S meanders in the plate width direction. The other brush roll parallel body is accompanyingly displaced in the same direction by means known per se (not shown). The guide device for moving the brush roll parallel body in the plate width direction can be one as shown in FIGS. The apparatus of FIGS. 1 and 3 is a sliding pair of a slide shoe 210 and a guide rail 211. The slide shoe 210 is attached to a base 213 of a saddle 212 coupled to the base 2, and the guide rail 211 is a polishing device. It is attached to the base 110 and extends in the strip S width direction.
[0027]
As described above, in the present invention, the peripheral surface polishing operation type is equivalent to the conventional brush roll for inclining at the side end with respect to the metal strip pass line and polishing this, and from the center of the row to the end. Each side has a plurality of two or more brush rolls arranged in parallel to each other in the direction inclined to the strip path line, and arranged in parallel at the end of the strip side (this configuration is a). Rotate in the opposite direction between adjacent ones (this configuration is b).
[0028]
According to the configuration (i) and (b) of the present invention, the parallel body by integrating the brush rolls as a whole has a concave curved surface (this configuration is referred to as C), and by selecting the rotation direction of the brush roll parallel body Then, it is possible to polish a region covering the front, back, and side end surfaces around the side edge of the strip (result A).
[0029]
When it is laid, the brush roll parallel body is arranged such that the higher-side outer brush roll is the brush roll on the side facing the strip S side end when viewed from the side of the higher end face (when viewed from the end face side). The circumferential surface is rotated in a direction corresponding to the rotation from the lower side to the upper side of the strip (in this case, it goes without saying that each brush roll rotates in the opposite direction between adjacent ones). ), That is, the rotation according to claim 2 and the drawing, the brush roll 1 in the arrangement shown in FIG. 1 with respect to the strip S (corresponding to the arrangement on the lower side of the paper in FIG. 6A), shown in FIGS. In the case of the arrangement of the brush rolls 1 (corresponding to the arrangement on the upper side of the paper in FIG. 6A) and the rotation in the direction of the arrows in FIGS. This will be explained in more detail with reference to FIGS. Then, it is as follows.
[0030]
The bristle B of the brush roll parallel body passes through the strip side end portion and behaves as shown in FIGS. In the polishing, the parallel order from the right side of FIG. 7 of each brush roll of the brush roll parallel body corresponds to the order of FIGS. 9, 10, 11 and 12, and the front and back center points of each brush roll are arranged in the parallel order of FIG. If (1), (2), (3), (4), (5), (6), (7), and (8) are used, the behavior of the bristle B of each brush roll is its (1), (▲) 2), (3), (4), (5), (6), (7), (8) are in the order of FIGS. 9 (A), (B), 10 (A), (B), This corresponds to the order of FIGS. 11A, 11B, and 12A, 12B. For ease of understanding this correspondence, FIGS. 9 (A), (B), FIG. 10 (A), (B), FIG. 11 (A), (B), FIG. 12 (A), (B) Reference numerals (1), (2), (3), (4), (5), (6), (7), and (8) are marked in this order.
[0031]
An analytical illustration of the polishing results for each brush roll in this case is as shown in FIG. In FIG. 8, the solid black portion at the end portion on the strip S side indicates the region where the polishing is performed, and the polishing results correspond to the polishing results by the brush rolls in order from the right in FIG. 7 in order from the top. The correspondence is shown in FIG. 8 with reference numerals (1) to (2), (3) to (4), (5) to (6), and (7) to (8). In FIG. 8, the lowermost polishing result is the entire brush roll parallel body, which is denoted by reference numerals (1) to (8). In FIG. 8, the instructions marked with (1) to (2), (3) to (4), (5) to (6), and (7) to (8) It represents the polishing region that is effective for ▼ to ▲ 2, ▼ 3 to ④, ▲ 5 to ▲ 6, and ▲ 7 to ▲ 8.
[0032]
That is, in the first rotation under the combination of the configurations A, B, and C, the brush roll parallel body is configured so that the outer brush rolls 1-1 and 1-4 are mainly located on the side end surface and the side end edge of the strip S. The brush rolls 1-2 and 1-3 inside thereof mainly contribute to the polishing of the front or back surface area around the strip S side end, and the polishing is performed with respect to the strip pass line P. Depending on the degree of deviation of the center of the strip toward the front or back side of the strip, the front or back side of the strip becomes a strong eye, and the result A is achieved as the entire brush roll parallel body. This polishing ability is particularly suitable for side edge polishing of a strip having a thickness of about 0.5 mm or more, which is plated on both the front and back surfaces during side edge polishing.
[0033]
In addition, in order to make it easier to understand the behavior of the bristle B polishing the strip side end, the brush roll at the right end in FIG. 7 which obtains the polishing results of the marks (1) to (2) in FIG. When the behavior of the bristle is shown in a microscopic and exploded view, the outline is as shown in FIGS. 19 (a) to 19 (e).
[0034]
FIG. 19 (a) shows the moment when bristle B contacts the lower edge of the strip. From this state, the bristle is bent as shown in FIG. 19 (b) to polish the lower edge while deepening the same bend, and the process shown in FIGS. Finally, as shown in FIG. 19 (e), the upper edge of the strip is bounced away and the upper edge is polished.
[0035]
It was recognized as a result of repeated grinding tests that the bristle polishing behavior was such an event.
[0036]
As for the brush rolls other than the right end of FIG. 7 and each brush roll of the brush roll parallel body of FIG. 13 described later, the bristle polishing behavior is determined by the degree of deviation of the center of the brush roll with respect to the front and back of the strip pass line P. The substance is the same as the above-described behavior except that the degree of bending of the bristle and the rubbing angle are different. Incidentally, when the rotation speed of the second brush roll from the right in FIG. 7 is increased to double the rotation speed of the first brush roll, the polishing results of the marks (3) to (4) in FIG. It was almost double the polishing result of (2) to (2). In view of the fact that the second brush roll is different from the first brush roll in the degree of phase deviation and rotation direction with respect to the pass line P, it is recognized that the substance of the polishing behavior of each brush roll is the same.
[0037]
In addition, according to the combination of the constitutions i, b, c, the direction of rotation of the brush roll parallel body is reversed from the first rotation. Specifically, the brush roll parallel body has the outer brush roll with the higher inclination. The brush roll in a direction corresponding to the rotation from the upper side to the lower side of the strip on the peripheral surface of the brush roll facing the end of the strip S side as viewed from the upper end (when viewed from the end surface) The parallel bodies are rotated (in this case, of course, each brush roll rotates in the opposite direction between adjacent ones), i.e. the rotation according to claim 3, with respect to the strip S in the drawing. 1 (corresponding to the arrangement on the lower side of the paper in FIG. 6A), the brush roll 1 having the arrangement shown in FIGS. 2 and 7 (corresponding to the arrangement on the upper side of the paper in FIG. 6A) Roll 1 is shown in FIGS. 1, 2 and 7 respectively. In the case of rotation in the direction opposite to the reference direction (this is referred to as second rotation), the front surface around the side edge of the strip S, the back surface area, the front surface of the side edge, and the back edge portion are mainly polished (result B). ). This is laid out with reference to FIGS. 13 to 18 as follows.
[0038]
The bristle B of the brush roll parallel body passes through the strip side end portion and behaves as shown in FIGS. In the polishing, the order of the brush rolls arranged in parallel from the right side of FIG. 13 corresponds to the order of FIGS. 15, 16, 17, and 18, and the front and back centers of the brush rolls are arranged in the order of parallelism in FIG. If 1 ▼, ▲ 2 ▼, ▲ 3 ▼, ▲ 4 ▼, ▲ 5 ▼, ▲ 6 ▼, ▲ 7 ▼, ▲ 8 ▼, the behavior of the bristle B of each brush roll is ▲ 1 ▼, ▲ 2 The order of ▼, ▲ 3 ▼, ▲ 4 ▼, ▲ 5 ▼, ▲ 6 ▼, ▲ 7 ▼, ▲ 8 ▼ is shown in FIGS. 15 (A), (B), FIGS. 16 (A), (B), FIG. This corresponds to the order of 17 (A), (B) and FIGS. 18 (A), (B). For convenience of understanding this correspondence, FIGS. 15A, 15B, 16A, 16B, 17A, 17B, 18A, 18B are arranged in that order. Reference numerals (1), (2), (3), (4), (5), (6), (7), and (8) are marked.
[0039]
An analytical illustration of the polishing results for each brush roll in this case is as shown in FIG. In FIG. 14, the solid black portion at the end portion on the strip S side shows a region where polishing is performed, and the polishing results correspond to the polishing results for the brush rolls in order from the right side of FIG. 13 in order from the top. The correspondence is shown in FIG. 14 with reference numerals (1) to (2), (3) to (4), (5) to (6), and (7) to (8). In FIG. 14, the bottom polishing result is the entire brush roll parallel body, which is denoted by reference numerals (1) to (8). In FIG. 14, the designations of (1) to (2), (3) to (4), (5) to (6), and (7) to (8) It represents the polishing region that is effective for ▼ to ▲ 2, ▼ 3 to ④, ▲ 5 to ▲ 6, and ▲ 7 to ▲ 8.
[0040]
That is, under the combination of the configurations (i), (b) and (c), in the second rotation, the brush roll parallel body is such that the outer brush rolls 1-1 and 1-4 mainly cover the front and back areas around the side edges of the strip S. The brush rolls 1-2 and 1-3 inside thereof are mainly effective in polishing the front and back edge portions of the strip side end, and the edge polishing is performed in the strip pass line P. On the other hand, depending on the degree of deviation of the center of the brush roll toward the front or back side of the strip, the front or back side of the strip becomes a strong eye, resulting in the result B as the entire brush roll parallel body. This polishing ability is particularly suitable for polishing the side edge of a strip whose front and back surfaces are plated and the plating is excessively attached to the side edge, for example, polishing of galvanization excessively attached to the edge of a hot dip galvanized steel sheet.
[0041]
According to the constitutions (i) and (b), in addition to polishing the metal strip side end, the brush roll parallel body can also function as a backup roll for polishing the strip end between adjacent brush rolls. Therefore, in the present invention, the backup roll which has been conventionally required is unnecessary.
[0042]
Configurations i and b correspond to a configuration in which two side end polishing brush roll machines arranged in the direction of the strip pass line in the brush roll parallel body on one side of the strip side end are integrated into one unit. According to the configuration of the present invention, even when the strip is thin, the occurrence of bending is extremely small and extremely good polishing can be obtained.
[0043]
【The invention's effect】
From the above description, it is apparent that the present invention achieves the following results in the metal strip side edge polishing in the manner described at the beginning.
[0044]
By selecting the rotation direction of the same brush roll (strictly, a parallel roll of brush rolls), it is possible to polish the three areas of the front, back and side edges around the side edge of the strip. The front, back region, front and back edge portions can also be polished.
[0045]
Polishing of the strip end can be performed without the need for a backup roll, and remarkably good polishing can be obtained even with a thin strip.
