Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electro-

The present invention relates to a cleaning device for an electroplated steel sheet, and more particularly, to a cleaning device for an electroplated steel sheet for cleaning edge portions on both sides in the width direction of an electroplated steel sheet with a grinding stone member.

Generally, the electroplating process is a process of coating a metal such as a steel sheet with an electric current. This electroplating fixation is carried out through an electrochemical reaction in which a steel plate to be plated is set as a negative electrode and put in a plating solution and current is passed through, whereby metal ions in the plating solution migrate to the negative electrode surface and precipitate.

FIG. 1 is a schematic view showing an electroplating process of a steel sheet, and FIG. 2 is a perspective view showing that an edge of a steel sheet is cleaned by a brush according to a conventional technique in a cleaning line in the electroplating process of FIG. 1 Reference numeral 38 denotes a feed roll, and reference numeral 39 denotes a water spray nozzle)

Referring to the drawings, the electroplating apparatus is roughly classified into a pre-treatment line 10, an electroplating line 20, and a rinse line 30, It passes through pretreatment, electroplating and rinsing (washing), and is produced as an electroplating product.

At this time, the steel plate 1 passes through the electroplating line and current concentration phenomenon occurs in the edge portion according to the environment such as the amount of plating and the applied current, so that the residues 2 due to dendrite growth, over- .

Thereby, the remnant 2 of the edge of the steel strip 1 is removed by using a brush roll made of a plastic brush in a rinsing line for washing the plating solution.

However, in fact, since the excess gold (2), which is generated in the edge portion of the steel sheet (1) in the electroplating process, is an electrochemical growth structure, it has a strong adhesive force and is limited to be removed by brushing. If it occurs, it can not be removed, and the entire electroplated product becomes defective.

Particularly, since the brush 31a of the brush roll 31 performing the brushing is made of a resin material, it is easily worn or damaged in the process of friction with the steel plate 1, and the life is very short. This decrease in service life is a factor that shortens the maintenance period of the process and affects the productivity.

The contact surface of the brush 31a with respect to the steel plate 1 reaches the side portion of the upper plate or the lower plate beyond the edge portion in the process of removing the residues of the edge of the steel plate 1, There is a limitation in that production of excellent electroplating products is disrupted.

It is an object of the present invention to provide a cleaning device for an electroplated steel sheet, which is developed to solve the above-mentioned problems, and in which a grinding stone member is configured to easily and effectively remove residues formed on an electroplated steel plate edge portion .

According to an aspect of the present invention, there is provided a cleaning apparatus for an electroplated steel sheet, comprising: a frame disposed at a rear end of an electroplating line; And cleaning means for cleaning edge portions on both sides in the width direction of the electroplated steel sheet, which are provided on the frame, with a grinding stone member.

Specifically, the cleaning means comprises: a cylindrical shaped grindstone member disposed to be inclined from the thickness direction of the steel plate toward the edge portion so as to grind the opposite side edge portions of the proceeding steel plate; And a rotation driving member for rotating the grinding wheel about an inclined shaft.

Here, the above-mentioned abrasive member may be arranged so as to be inclined toward the longitudinal direction of the steel plate in the width direction of the steel plate so that a constant width in the longitudinal direction at the time of rotation is in contact with the edge portion of the steel plate.

In addition, the rotation drive member can control the rotation of the grindstone member so that the grindstone member grinds the steel plate in the reverse direction.

The cleaning unit may further include a reciprocating driving member for reciprocating the rotation driving member in an inclined axis direction of the grindstone member so as to reciprocate the grindstone member in an inclined axial direction.

On the other hand, the cleaning means is the grindstone member, which is an upper grindstone for grinding the upper edge of the edge portion of the steel sheet; And a lower grinding wheel for grinding the lower edge of the edge portion of the steel sheet.

At this time, the upper and lower grindstones may be spaced apart from each other in the longitudinal direction of the steel plate.

Also, the reciprocating drive member may be driven and controlled such that the upper and lower grindstones are simultaneously moved upward or downward.

The cleaning apparatus of the electroplated steel sheet according to the present invention can easily remove the residues formed on the edge of the steel plate by grinding and cleaning the electroplated steel sheet with the edge portions of the electroplated steel sheet in the width direction on the inclined surface and rotating the steel plate. It is possible to arrange the edge portions without separately performing the edge trimming process for arranging the edge portions on both sides of the edge portion.

Further, the present invention maximizes the service life of the cleaning means as the grindstone member reciprocates on the inclined axis while being inclined from the thickness direction of the steel plate to the edge portion side, so that the work load and the working time for the maintenance of the cleaning means It is advantageous in terms of productivity.

The cleaning apparatus for an electroplated steel sheet according to the present invention is configured such that edge portions on both sides in the width direction of the electroplated steel sheet are grinded and rotated by a rotating grindstone member so as to easily and effectively remove the residues formed on the edge of the steel sheet It is a technical feature.

Further, in order to maximize the service life of the cleaning means, the grindstone member is arranged to be inclined from the thickness direction of the steel plate to the edge portion, and is reciprocated by an inclined shaft.

For reference, in the present specification, the remnant of the steel sheet refers to a portion formed by protruding the edge portion (upper edge or lower edge) due to various reasons such as current concentration phenomenon while the steel sheet passes through the electroplating line. For example, Growth, over-plating, or the like.

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 3 is a perspective view of a cleaning apparatus for an electroplated steel sheet according to a preferred embodiment of the present invention. FIG. 4 is a cross- (Reference numeral 38 in Fig. 3 denotes a transport roll, and reference numeral 39 denotes a water spray nozzle). Fig.

Referring to the drawings, the present invention includes a frame disposed at the rear end of an electroplating line (20 in FIG. 1) and a cleaning means provided in the frame.

At this time, although not shown in the drawings, the frame is disposed at the rear end of the electroplating line, that is, the rinse line (30 in FIG. 1), and is a structure for fixing the cleaning means described later.

Needless to say, these frames need only be structured such that the cleaning means is firmly fixed to the cleaning means so that the cleaning means can efficiently remove the remnants of the steel plate 1. According to the present invention, Do not.

The cleaning means is configured to clean edge portions of both sides in the width direction of the electroplated steel sheet 1 by the grinding stone 110.

Specifically, the cleaning means may include a grinding stone 110 for grinding both side edges of the steel strip 1, and a rotation driving member for rotating the grinding stone 110.

The cleaning means includes an upper grinding wheel 111 for grinding the upper edge of the steel sheet 1 at the edge of the steel sheet 1 and a lower grinding stone 112 for grinding the lower edge of the steel sheet 1 ). As described above, in this specification, the grinding wheel 110 refers to the upper grinding wheel 111 or the lower grinding wheel 112, and the upper grinding wheel 111 or the lower grinding wheel 112, .

The grindstone member 110 may be arranged to be inclined from the thickness direction of the steel plate 1 to the edge portion side in a cylindrical shape so as to grind the opposite side edge portions of the progressing steel plate 1. [

The upper and lower grind stones 111 and 112 may be disposed on the upper edge side of the steel plate 1 and the lower grind stone 112 on the lower edge side. The upper edge and the lower edge, respectively.

Since the grindstone member 110 having the above-described arrangement structure comes into contact with only the edge portion of the steel strip 1, it is possible to effectively remove only the residues formed on the edge portion without abrading the other portions of the steel strip 1. [

The rotation driving member also functions to rotate the upper or lower grinding wheel 111 or the grinding wheel 110 about the inclined shaft 119. At this time, it is preferable that the rotation driving member provides a uniform abrasion force to the steel strip 1 by making the rotation speed of the upper and lower grind stones 111 and 112 the same.

For example, as shown in FIG. 4, the rotation driving member may be a motor 120 connected to the upper and lower grinding wheels 111 and 112, which are the grinding wheel 110, It is needless to say that any driving member may be utilized as long as the upper or lower grinding wheel 111 or 112 is rotated so as to remove the residues at the edge of the steel plate 1. [

The rotation driving member controls the rotation of the grinding wheel 110 so that the grinding wheel 110 grinds the steel strip 1 in the reverse traveling direction, The direction of rotation of the grindstone member 110 can be determined so that the portion of the grindstone member 110 that is in contact with the steel plate 1 is rotated in the reverse direction of the steel plate 1.

As a result, the edge portion of the steel strip 1 is grinded in the reverse direction by the grinding stone member 110. Accordingly, the abrasion effect of the steel strip 1 by the grinding stone 110 is increased, But it can be cleanly removed.

Of course, at this time, the progress of the steel plate 1 can be delayed by grinding the grinding wheel 110 in the reverse direction to the steel plate 1. As the progress of the steel plate 1 progresses substantially in the electroplating process, Rotation of the grinding wheel 110 hardly affects the traveling of the grinding wheel 1 in the course of the grinding process.

The edge portion of the steel plate 1 is grinded in the reverse direction by the grinding stone member 110 so that the remaining portion of the steel plate 1 that is grinded and separated by the grinding stone member 110 is moved upward, To the upper surface of the substrate.

Specifically, when the grinding wheel 110 is grinding while rotating in the advancing direction in the course of grinding the edge portion of the steel strip 1, the remaining portion of the steel strip 1 is separated from the edge portion in the traveling direction of the steel strip 1 The steel plate 1 can be moved upward and can be seated on the upper surface of the steel plate 1. [ However, when the grinding wheel 110 is grinding while rotating in the counterclockwise direction, the remnants of the steel strip 1 are blocked by the grinding stone 110 when being separated from the edge portion and pushed in the anti-moving direction of the steel strip 1 And falls downward.

The cleaning unit may further include a reciprocating driving member for reciprocating the grinding wheel 110 in the direction of the inclined shaft 119.

4, a cylinder 130 having a motor 120 for rotating the grinding member 110 and a cylinder rod 131 fastened and fixed may be used as the reciprocating driving member, The grinding wheel 110 can reciprocate in the direction of the inclined shaft 119 by the expansion and contraction movement of the rod 131.

Of course, the reciprocating drive member is not limited to this, and any mechanical structure such as a cam structure may be utilized as long as the grindstone member 110 reciprocates in the direction of the inclined shaft 119.

The grinding member 110 is worn as the grinding portion of the edge of the steel plate 1 is continuously used. As the grinding member 100 is reciprocated by the reciprocating driving member as described above, It is not localized, and as a result, the service life is increased.

It is preferable that the upper and lower grindstones 111 and 112 of the grinding wheel 110 are spaced apart from each other in the longitudinal direction of the steel strip 1.

That is, the upper and lower grind stones 111 and 112 are cylindrically shaped and are reciprocated by the reciprocating driving member. Thus, in the thin steel sheet 1, the upper and lower grind stones 111 and 112 are disposed at the upper and lower edges, They can be set apart from each other in the longitudinal direction of the steel plate 1 within an appropriate range according to the narrow space.

Meanwhile, the reciprocating drive member can be driven and controlled such that the upper and lower grindstones 111 and 112 move upward or downward at the same time.

3, when the upper grinding stone 111 is moved upward and the lower grinding stone 112 is moved downward to grind the edge portion of the steel strip 1, the rear portion of the steel strip 1 is divided into the upper grinding stone 111 and the front portion of the steel strip 1 is lowered by the lower grinding stone 112, the stable progress of horizontal movement of the steel strip 1 can not be achieved.

Each of the reciprocating drive members associated with the upper and lower grindstones 111 and 112 is driven and controlled so that the upper or lower movement of the upper and lower grindstones 111 and 112 is synchronized, The grinding effect on the edge portion of the steel strip 1 can be enhanced and the damage to the steel strip 1 can be prevented.

More preferably, the reciprocating drive member further includes a grindstone member 110 which is in contact with one edge portion of the steel plate 1 in the width direction of the steel plate 1 and a grindstone member 110 which is in contact with the other edge portion of the steel plate 1 , And can be driven and controlled to move upward or downward at the same time.

3 and 4, the grindstone member 110 is disposed at an angle to the longitudinal direction of the steel plate 1 with respect to the width direction of the steel plate 1 as shown in Fig. 5, .

Fig. 5 is a plan view showing that the grinding wheel is inclined in the width direction of the steel plate in the cleaning apparatus of the electroplated steel sheet of Fig. 3; Fig.

Referring to FIG. 1, the grinding wheel 110 is arranged to be inclined in the longitudinal direction of the steel plate 1 with respect to the width direction of the steel plate 1 such that a constant width in the longitudinal direction of the grinding wheel 110 is in contact with the edge of the steel plate 1 .

Specifically, when the grinding wheel 110 is arranged on a plane, the grinding wheel 110 is moved in the longitudinal direction of the steel strip 1 with respect to the width direction of the steel strip 1, ) Or in a backward direction.

3 and 4, the contact portion of the grinding wheel 110 with respect to the edge portion of the steel plate 1 is linearly formed during rotation, and in order to prevent local abrasion of the grinding stone 110, And is configured to reciprocate in the direction of the inclined shaft 119 by the member.

On the other hand, the grinding member 110 shown in Fig. 5 is structured such that it is inclined in the longitudinal direction of the steel plate 1 in a planar manner with respect to the width direction of the steel plate 1, Since the contact portion with respect to the edge portion of the steel strip 1 is formed to have a constant width 110a in the longitudinal direction (of the grinding wheel), it is possible to prevent local abrasion of the grinding wheel 110 without the reciprocating drive member .

Further, in the present invention, it is of course possible to apply the arrangement structure of the grinding member 110 of Fig. 5 to Figs. 3 and 4 (a reciprocating drive member is constituted).

The present invention configured as described above is characterized in that edge portions on both sides in the width direction of the electroplated steel sheet 1 are removed by grinding with a rotating grindstone member 110 arranged in an inclined manner to easily remove the residues formed on the edge of the steel strip 1 And further has an overlapping function of arranging the edge portions without separately performing the edge trimming process for arranging the edge portions on both sides of the steel strip 1. [

The present invention maximizes the service life of the cleaning means as the grinding wheel 110 reciprocates on the inclined shaft 119 while being inclined from the thickness direction of the steel plate 1 to the edge portion side, It has the advantage of productivity efficiency by reducing workload and work time for maintenance.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is to be understood that various changes and modifications may be made without departing from the scope of the appended claims.
