Description

Foreign Matter Removal Type Steel Sheet Transferring Roll

The present invention relates to a steel sheet transport roll for removing foreign substances, and more specifically, foreign substances such as contaminants such as (oxidized) scale, dust, powder, oil, cleaning solution, etc. attached to the surface of hot rolled or cold rolled steel sheets or scattered around the surface. On the other hand, it is possible to effectively remove, while at least a deflector roll (Deflector Roll) or a bridle roll (Bridle Roll), the foreign matter removal type steel sheet transfer roll, which is replaceable.

When coiling or uncoiling a hot or cold rolled steel sheet, the oxidation scales generated on the steel sheet surface fall off and are accumulated on the surface of the steel sheet or scattered around it. Causes problems.

Or, in order to increase the efficiency of iron loss in the manufacture of electrical steel sheet, after applying and annealing the non-magnetic MgO powder in an aqueous solution, unreacted MgO powders come off the surface of the steel sheet, causing indentation, pressing, etc. on the steel sheet. Surface bonding occurs.

Alternatively, residual contaminants such as oil such as rolling oil when rolling a steel sheet or a cleaning solution when cleaning a steel sheet may be generated.

On the other hand, in order to process such various types of foreign substances, it was previously processed using a dust collecting hood surrounding a certain area, but in an environment in which a steel sheet is transported, there is a limit that can be treated with a dust collecting hood, and suction of foreign substances It was less efficient.

Thus, with other conventional techniques, foreign substances on the surface of the steel sheet were removed through a suction roll (dust roll, vacuum roll, etc.) that is in line contact with the steel sheet being transferred.

For example, KR 10-2010-0072639 A (2010.07.01) discloses a technique for removing foreign substances on the surface of a strip through a vacuum suction roll, and KR 10-2015-0073494 A (2015.07.01) vacuum pump Disclosed is a technique for removing rolling oil on a steel sheet using a suction roll connected to.

However, the suction rolls of the disclosed patents are small-diameter rolls having a diameter that is substantially in line contact with the steel sheet, and based on the suction roll with only holes formed, the suction efficiency of the foreign matter was not substantially large, and the particle size of the sucked foreign matter was also It was either limited or limited to liquid.

Particularly, in the case of the suction rolls of the above-mentioned patents, the steel sheet conveying rolls such as deflector rolls or bridle rolls (which at least switch the conveying direction of the steel sheet) are used in a continuous conveying environment of hot rolled or cold rolled steel sheets (wide). It was impossible.

In addition, KR 10-1294017 B1 (2013.08.01) discloses a vacuum suction roll, which is limited to use as an environment for inhaling residual liquid, such as a cleaning liquid on the surface of a strip product.

On the other hand, the registered patent discloses a suction structure setting member of a wing structure for setting (segmenting) a suction space. However, since the wings of the suction direction setting member are positioned only in the set direction, it was impossible to automatically (mechanically) change the position of the wings mechanically during roll operation.

Moreover, the above-mentioned registered patent is a small-diameter roll having a small diameter in line contact with a steel sheet, and the foreign matter to be treated is limited to liquid, and is based on a suction roll having holes formed therein.

Therefore, even in the case of the above-mentioned registered patent, it is also used in a continuous conveying environment of (wide) hot rolled or cold rolled steel sheet as a steel sheet conveying roll such as a deflector roll or bridle roll (which changes at least the conveying direction of the steel sheet). It was impossible.

KR 10-2010-0072639 A (2010.07.01) KR 10-2015-0073494 A (2015.07.01) KR 10-1294017 B1 (2013.08.01)

Hereinafter, the present invention will be described in detail through exemplary drawings. It should be noted that in adding reference numerals to the components of each drawing, the same components have the same reference numerals as possible even though they are displayed on different drawings.

In addition, in describing the present invention, when it is determined that detailed descriptions of related well-known structures or functions may obscure the subject matter of the present invention, detailed descriptions thereof will be omitted.

Hereinafter, preferred embodiments of the present invention will be described in detail.

FIG. 1 shows a foreign material removing type steel sheet transfer roll 100 of the present invention in one embodiment, and FIG. 2 shows a use state of the foreign material removing type steel sheet transfer roll 100.

However, in the following description of the present embodiment, the description of the'foreign material removal type steel sheet conveying roll' is abbreviated as'steel sheet conveying roll 100', and according to the embodiment, the steel sheet conveying roll will be described with reference numerals of 100,200,300,400. In addition, the characteristic components related to the steel sheet transport paths 100, 200, 300, and 400 of each embodiment are described by dividing them with reference numerals of 100, 200, 300, and 400. Of course, components common to the steel sheet transport rolls of various embodiments are briefly described in the embodiments described below.

First, as shown in Figures 1 and 2, the steel sheet transport roll 100 of the present invention of one embodiment, the suction hollow body 110 and the steel plate 10, which is associated with an external dust collecting line (20 in FIG. 9) ) Is provided to be rotatable to the suction hollow body 110 so as to be transported while contacting them, and a plurality of suction hole holes 120 for sucking the foreign material S while communicating with the suction space (132 in FIG. 6) formed therein It may be provided, including a suction roll 130 provided.

That is, the steel sheet transport roll 100 of the present invention can be provided in the form of a large-diameter roll compared to the above-mentioned [Patent Documents], and the suction roll 130, in particular, is conventional suction that is densely arranged in its length and circumferential direction. It is provided with suction port holes 120 having a width (a) and a length (b) different from the simple circular holes of the roll.

And, as shown in Figure 2, the steel sheet conveying roll 100 of the present invention, the oxidation scale of the surface of the steel sheet 10 through the plurality of suction hole holes 120 densely provided on the suction roll 130, (fine ) It will be able to effectively remove various types of foreign substances (S), such as dust, powder, or contaminants such as oil or cleaning liquid, and remove them.

For example, as shown in FIG. 2, the steel sheet transport roll 100 of the present invention has a completely different dimension from the small-diameter suction rolls having small diameter holes formed in line contact with the steel sheet in the existing [patent document], the steel sheet 10 By replacing the steel sheet conveying roll 100 such as a deflector roll (100b) or a bridle roll (100a) in which the steel sheet is in surface contact while the conveying direction is switched or tension is applied while winding. It doesn't matter at all.

That is, as described in detail below, the present invention can be provided by reflecting an optimization design such as improving the frame structure of a roll. However, in the following description of the present embodiment, the suction hollow body will be described as the suction pipe 110.

Next, as shown in Figures 1 and 3, the suction hole 130 is arranged densely to increase the suction efficiency of foreign matter in the suction roll 130 of the present invention, the predetermined width (a) and length (b) It can be provided to have.

For example, as shown in Figure 3, the width (a) and length (b) of the suction hole (120) of the suction roll 130, at least maintain the curvature of the suction roll 130 and the surface of the steel sheet (10) It can be provided to satisfy the following equation (1) so as not to cause damage to the.

For example, as shown in FIG. 3, when the width (a) of the suction hole 120 is greater than 1/3 b (length), the suction hole 120 does not correspond to the curvature of the suction roll 130 and is almost While being flattened, the surface of the steel sheet 10 transferred in contact with the suction roll 130 will be scratched at the edge of the roll surface side of the suction hole 120, and a mark (blemish) will be generated on the surface of the steel sheet.

In addition, when the width (a) of the suction hole 120 is smaller than 1/10 b (length), the width of the suction hole 120 is too small, so that the inhalation efficiency of foreign matter decreases, or suction of a scale with large particles, etc. It will make it difficult.

In addition, the length (b) of the width (a) of the suction hole 120 may be set within a range that maintains at least the rigidity of the steel sheet conveying roll 100.

Therefore, the suction field holes 120 of the present invention may be provided to satisfy the condition of Equation 1 above.

Next, as shown in Figure 4, in the steel sheet conveying roll 100 of the present invention, the suction hole 130 of the suction roll 130, at least to prevent damage to the surface of the steel sheet to be conveyed, the roll surface side The corner portion may further include a chamfer surface 122 that is not sharply processed. For example, chamfering may be performed to be partially cut along the edge (circumference) of the roll surface side of the suction hole 120.

In addition, the suction hole 120 may further include a rounding surface 124 at which both ends (edge portions) are curved with a preset curvature r.

Therefore, even if the steel sheet conveying roll 100 of the present invention is replaced by a deflector roll (100b in FIG. 2) or a bridal roll (100a in FIG. 2), the steel sheet is in contact with the surface due to the nature of being conveyed while being wound on the roll. It does not cause damage such as surface defects to the steel plate surface.

In addition, as shown in Figure 4, the surface of the suction roll 130 may be further formed a coating layer (126). 2, the coating layer 126 on the surface of the suction roll reduces friction due to contact between the steel sheet 10 and the suction roll 130 even when the steel sheet 10 is transferred in surface contact, as shown in FIG. 2. It will not be damaged.

For example, a soft coating layer 126 such as urethane may be formed on the surface of the suction roll 130, or the chromium coating layer 126 may be coated according to process requirements.

As a result, the steel sheet suction roll 130 and the suction hole 120 provided in the suction roll of the present invention may reflect an optimization design that prevents factors that cause damage to the steel sheet surface even if the steel sheet is transported in surface contact. have.

Next, as shown in Figure 5a, the suction hole (120) provided in the suction rolls 130 of the present invention is arranged in the longitudinal direction of the suction roll 130, but the front and rear can be arranged alternately have.

Or, as shown in Figure 5b, the suction hole 120 is arranged to have a length in the circumferential direction of the suction roll 130, the front and rear may be staggered.

Or, as shown in Figure 5c, the suction hole 120 may be arranged in a diagonal direction of the suction roll (130).

For example, various arrangements of the suction hole holes 120 of the present invention of FIG. 5 may be appropriately set in consideration of a transfer environment of the steel sheet 10 or an environment in which foreign substances are generated, such as a scale.

Next, Figure 6 is a cross-sectional view of the X-X' line of Figure 1, showing the steel sheet transfer roll 100 according to the present invention.

For example, as shown in Figure 6, the steel sheet transfer roll 100 according to the present invention, the external dust collecting line (20 of FIG. 9) is connected and the suction pipe (112) having at least one suction opening (112) 110), the suction pipe 110 is rotatably provided, the steel sheet 10 is contacted and transported, and a suction roll provided with a plurality of suction hole holes 120 communicating with the internal suction space 132 to suck foreign matter It may be configured to include 130 and at least one diaphragm member 150 provided to partition the suction space 132 while surrounding it on the suction opening 112.

Meanwhile, FIGS. 7A and 7B show a case where the steel sheet transport roll 100 of the present invention is used as a deflector roll 100b.

That is, as shown in Figures 6 and 7, the steel sheet transfer roll 100 of the present invention, when the dust collecting force is applied to the suction pipe 110 to which the external dust collecting line (20 of FIG. 9) is connected, the suction pipe 110 ) The suction opening 112 and the diaphragm member 150 that extends toward the suction hole 120 of the suction roll 130 while enclosing it, partitions the internal suction space 132 of the suction roll 130 Is done.

Therefore, the internal suction space 132 is sucked by foreign matter through the internal suction concentration space 132' of the diaphragm member 150 that is surrounded while communicating with the suction opening 112, so that the foreign matter suction capacity will be increased.

Meanwhile, as illustrated in FIG. 7A, when the steel sheet 10 enters the upper side of the deflector roll 100b, correspondingly, the suction opening 112 and the diaphragm member 150 of the suction pipe 110 are approximately 1 on the upper side. It can be positioned in the o'clock direction (it can be set at roll installation).

Or, as shown in Figure 7b, when the steel sheet 10 enters the lower side of the deflector roll (100b), correspondingly the suction opening 112 and the diaphragm member 150 of the suction pipe 110 is approximately 5 downwards It can be positioned in the hour direction (it can be set at roll installation)

Of course, FIG. 7 shows that the present invention steel sheet conveying roll 100 is used by being replaced with a deflector roll 100b, and the suction opening 112 and the diaphragm member of the suction pipe 110 according to the roll entry position of the steel sheet It is natural that the position of the 150 is not necessarily limited as shown in FIGS. 7A and 7B. It is natural that their position can be properly adjusted.

Therefore, the present invention steel sheet conveying roll 100, the suction member 112 of the suction pipe 110 and the diaphragm member 150 forming the inner suction concentration space 132' is at least in the position to enter the conveying roll of the steel sheet Accordingly, it can be set and adjusted to the wash position.

That is, the suction pipe 110 is a fixed body, but since the suction roll 130 is assembled to be idle, when the suction pipe 110 is fixed to the outer frame (30 in FIG. 9), the suction of the suction pipe 110 is performed. The positions of the opening 112 and the diaphragm member 150 may be set in advance.

Next, FIG. 8 is an enlarged view of'B' in FIG. 6 and shows the assembled state of the steel sheet transfer roll 100 of the present invention.

That is, as shown in FIG. 8, the suction roll 130 of the steel sheet transfer roll 100 of the present invention is provided with a predetermined length in the suction pipe 110 (which may be a fleece structure), a reinforcing part 134 ) A flange portion 138 which is a side wall of a roll provided rotatably via a bearing 136 assembled to the rib, a rib ring member 140 having a circular ring structure assembled to the flange portion 138, and the rib member 140 ) Is fixed by welding or the like on both sides of the inner surface, and may be provided as a cylindrical roll body portion 142 having suction suction holes 120 formed thereon.

In addition, one side of the bearing 136 is supported by a lower stepped portion (unsigned) of the flange portion 138, and the other side of the bearing 136 penetrates the reinforcement portion 134 of the suction pipe 110. Thus, the flange portion 138 may be supported by a retainer 144 assembled as a bolt (B).

On the other hand, as shown in Figure 8, the flange portion 138 and the rib member 140, the bolt (B) is fastened to the part overlapping each other (unsigned) can be assembled to be disassembled if necessary.

At this time, the reinforcement portion 134 of the suction pipe 110 is in contact with the inner ring of the bearing 136, the flange portion 138 is in contact with the outer ring of the bearing 136, the rib to the flange portion 138 Since the member 140 and the cylindrical roll body part 142 are assembled, the suction roll 130 may be provided to be idle at the suction pipe 110.

For example, as shown in Figure 8, the present invention steel sheet transfer roll 100, suction pipe 110 + reinforcing portion 134 + flange portion 138 + rib member 140 + roll body portion 142 + retainer ( Because it is based on the solid assembly structure of 144), even if it is completely replaced by a steel plate conveying roll such as a deflector roll or bridal roll, there is no problem in maintaining roll rigidity.

And, since the bolts B are assembled in the circumferential direction along the flange portion 138, disassembly is possible at any time, which is described in the suction pipe 110 and the diaphragm member 150 inside the suction roll 130, and To facilitate the installation of the reinforcing ribs 170 and the like, it will also facilitate the transport roll maintenance.

For example, with the suction pipe 110 and the diaphragm member 150 entering the inside of the cylindrical roll body portion 142, the flange portion 138 and the bearing on the reinforcement portion 134 of the suction pipe 110 Assembling (136), the flange portion 138 and the rib member 140 and the bolt assembly, and finally the retainer 144 may be bolted to the flange portion of the outer bearing.

On the other hand, the cylindrical roll body portion 142, the metal plate (base material), after processing the suction hole 120 in the proper arrangement shown in Figure 5, and then rolled the metal plate into a cylindrical body to form, roll body portion 142 Can be provided.

Next, as shown in FIGS. 8 and 13, the diaphragm member 150 has a main diaphragm 152 and a main diaphragm 152 fixed in the longitudinal direction of one or more suction openings 112 formed on the suction pipe 110. It may be made of a side wall diaphragm 154 provided (assembled or welded) to the edge portion of the.

Therefore, the inner space formed by the main diaphragm 152 and the sidewall diaphragm 154 of the diaphragm member 150 surrounding the suction opening 112 of the suction pipe 110 to which external dust collecting force is applied, that is, a closed space, that is, The suction concentration space 132' is formed.

In addition, since the diaphragms 152 and 154 of the diaphragm member 150 extend from the suction opening 112 to the vicinity of the suction hole 120 of the suction roll 130, the externally applied dust collecting force is the suction concentration space 132 ') to increase the ability to inhale foreign substances sucked through the suction hole 120 corresponding thereto.

Next, Fig. 9 shows the installation state of the steel sheet transport roll 100 of the present invention.

That is, as shown in Figure 9, the suction pipe 110 is fixed to the outer frame 30, the dust collecting equipment at both ends of the suction pipe 110 extending through the outer frame 30, that is , The dust collecting line 20 connected to the vacuum pump may be connected via a coupling 22 or the like.

Of course, the dust collecting line 20 is connected to only one side of the suction pipe 110, and the opposite side of the suction pipe may be sealed, but in order to stably maintain the suction ability, it is collected at both ends of the suction pipe 110. The line 20 is to be connected.

Next, FIG. 10 shows a steel sheet transport roll 200 according to another embodiment of the present invention. However, the same components as those of the steel sheet transfer roll 100 of one embodiment described above are denoted by the same reference numerals, and the detailed description thereof is brief.

First, as shown in FIG. 10, in the steel sheet conveying roll 200 of another embodiment of the present invention, the suction pipe 110 may be rotatably provided on the outer frame 30 via the driving means 210. .

Accordingly, it will be possible to selectively and mechanically change the positions of the suction opening 112 and the diaphragm member 150 fixedly connected to the suction opening integrally with the suction pipe 110.

That is, the position of the suction concentration space 132 ′ inside the diaphragm member partitioned by the diaphragm member 150 may be mechanically varied at a desired time point.

10, the suction pipe 110 may be rotatably provided on the outer frame 30 via a bearing 114, and both ends of the suction pipe 110 may rotate the suction pipe 110 It can be connected to the external dust collecting line 20 via the rotary joint 24 to compensate.

In addition, the driving means 210 is provided with at least one side of the driving gear 214 driven as a driving motor 212 linked to the outer frame 30 and the suction gear 110 engaged with the driving gear. It may include a driven gear 216.

Or, although not shown in a separate drawing, the drive means 210, a chain driven as a drive motor connected to the outer frame 30 is fastened, the sprocket provided on at least one side of the suction pipe 110 It may be provided, including.

Accordingly, the suction pipe 110 in which the diaphragm member 150 is fixed around the suction opening 112 is driven gear 214 engaged with each other according to the operation of the driving motor 212 of the driving means 210 And according to the rotation of the driven gear 216, or according to the rotation of the sprocket and the drive chain (not shown), it may be rotated on the outer frame 30.

For example, as shown in Figure 7a, when the steel sheet 10 enters the upper side of the deflector roll (100b), the steel sheet transfer roll 200 of the present invention, as shown in Figure 10, the drive of the drive means 210 By operating the motor 212, the positions of the suction pipe 110 and its suction opening 112 and the diaphragm member 150 are mechanically variable at approximately 1 o'clock in the inner suction space 132 of the suction roll 130. I can do it.

Conversely, as shown in FIG. 7B, when the steel sheet 10 enters the lower side of the deflector roll 110b, the driving motor 212 is controlled accordingly to control the suction pipe 110 and its suction opening 112 and the diaphragm member ( The position of 150) may be mechanically variable in the internal suction space 132 at approximately 5 o'clock.

As a result, the steel sheet conveying roll 200 according to another embodiment of the present invention does not require the operator to set the position of the opening and the diaphragm member of the suction pipe when the steel sheet conveying roll 100 is installed, and foreign matter such as a conveying environment or scale of the steel sheet is generated. Corresponding to the environment, it will be possible to mechanically change the positions of the suction pipe 110 and its suction opening 112 and the diaphragm member 150 quickly.

More preferably, as shown in FIG. 10, the gear-side drive motor 212 or the chain-side drive motor (not shown) provided in the driving means 210 may be associated with the control unit C.

In addition, the control unit (C) may be associated with information (dotted line) or camera 40 for measuring the occurrence of foreign matter on the transfer roll entry position of the steel sheet 10. Corresponding to the generated (scattering) environment, the positions of the suction pipe 110 and its suction opening 112 and the diaphragm member 150 are automatically (mechanically) in the internal suction space 132 of the suction roll 130. You will have variable control.

This will further enhance the ability to inhale foreign substances through the steel sheet conveying roll 200 of the present invention, and enable more optimal removal of foreign substances while rapidly responding to the surrounding environment.

Next, FIGS. 11 and 12 show another embodiment of the steel sheet transfer roll 100 and 200 of the present invention described above.

For example, at least one reinforcing rib 170 on the inner circumferential surface of the cylindrical roll body 142 of the suction roll 130, preferably, a plurality of reinforcing ribs 170 may be further provided at regular intervals. . Such a reinforcing rib 170, while being welded and fixed to the inner surface of the cylindrical roll body portion 142, will further enhance the overall rigidity of the steel sheet conveying roll.

Of course, in the case of the steel sheet transfer rolls 100 and 200 of the present invention described above, as the structural rigidity of the roll frame, the bridle roll (100a in FIG. 2) or deflector roll (in FIG. 100b), there will be no problem at all.

However, as shown in FIGS. 11 and 12, the at least one reinforcing rib 170 further increases the rigidity of the roll, thereby extending the service life of the roll, and in particular, the surface of the steel sheet 10 of wide width is applied while applying a load. Even if it is transferred while being contacted and wound, it will be possible to prevent damage to the transfer roll.

In addition, the reinforcement ribs 170 of the present invention. Even if the suction hole holes 120 are densely formed through the cylindrical roll body portion 142 of the suction roll 130, the rigidity of the suction roll 130 will be maintained stably.

Such a reinforcing rib 170, a plurality of regular intervals on the inner surface of the cylindrical roll body portion 142 of the suction roll 130 has a height set in the form of a circular ring can be fixed by welding.

Of course, the width (height) or thickness of the reinforcing ribs may be appropriately designed in consideration of a load applied by the steel sheet.

On the other hand, as shown in Figure 11, when the reinforcing rib 170 is provided, the main diaphragm 152 of the diaphragm member 150 described above, the reinforcing rib 170 through the incision (152') May be further formed.

Alternatively, as shown in FIG. 12, the width of the main diaphragm 152 of the diaphragm member 150 may be reduced to allow the diaphragm members 150 to be positioned between the reinforcing ribs 170.

Of course, the installation number of the suction openings 112 of the suction pipe 110 will be adjusted in correspondence to the installation number of the diaphragm member 150.

Next, as shown in Figure 13, at least one convex inclined plate 156 of the inside of the main diaphragm 152 of the diaphragm member 150 in the steel sheet transfer roll 100, 200 of the present invention described so far has been described More can be provided.

Preferably, the convex inclined plate 156 may be arranged to face a pair provided on the main diaphragm 152 on both sides of the diaphragm member 150, and the central portion of the convex inclined plate 156 protrudes. It can be a structure.

Therefore, since the gap is narrowed at the maximum protruding portion between the convex inclined plates 156 facing from the inside of the diaphragm member 150, on the contrary, the flow rate is increased, and consequently, the internal suction concentration space 132 of the diaphragm member 150 ') will be able to increase the ability to inhale foreign substances.

Next, as shown in Figure 13, the opening angle of the diaphragm member 150, that is, the opening angle (α) of the main diaphragm 152 facing both sides of the diaphragm member 150, the following equation (2) Can be satisfied.

That is, if the separation angle α of the main diaphragms 152 of the diaphragm member 150 is spaced apart from the steel sheet 10 without being in contact with the transport roll 100, foreign matter is not sucked, so the steel sheet 10 is transported to the steel sheet It should be equal to or smaller than the angle θ surrounding the roll 100.

Of course, if the capacity of the dust collecting power through the dust collecting equipment is increased, the opening angle of the diaphragm member 150 may not be significantly affected, but the increase in the dust collecting power (suction input) increases the capacity of the dust collecting equipment. It can be a problem.

Therefore, in the case of the present invention, it will be desirable to make the steel sheet 10 larger than 1/3 of the angle (θ) surrounding the roll based on the cross-sectional area of the suction pipe 110 and the set suction force affecting the suction force.

Of course, the opening angle α of the diaphragm member 150 is maximized to be greater than or equal to the angle θ of the steel sheet surrounding the roll to the maximum.

For example, in the case of the deflector roll 100b described in FIGS. 2 and 7, the steel sheet 10 is transferred while wrapping the roll up to 180° while changing directions.

Therefore, considering such an environment such as a deflector roll, when the opening angle α of the diaphragm member 150 is larger than the above-mentioned range, the cross-sectional area of the internal suction concentration space 132' is too wide and the suction power is reduced.

Conversely, when the opening angle α of the diaphragm member 150 is smaller than the above range, it may not be possible to effectively maintain foreign matter suction such as a scale in response to the rotational speed of the roll (feeding speed of the steel sheet). That is, in the case of a cold rolled steel sheet having a fast transfer speed of the steel sheet, suction of foreign substances may be reduced.

Next, FIG. 14 shows a steel sheet transport roll 300 according to another embodiment of the present invention. However, the same configuration as the steel sheet transfer roll described above is denoted by the same reference numerals, and its detailed description is brief.

First, as shown in FIGS. 14A and 14B, in the steel sheet transport roll 300 of the present invention, the suction pipes 110 are bent portions 310 on both sides formed in the internal suction space 132 of the suction roll 130. ) May be provided as a bent suction pipe 110 further comprising.

The bent portion 310 of the bent suction pipe 110 is compared with the suction opening 112 of the suction pipe 110 compared to the straight suction pipe 110 of the steel sheet transfer rolls 100 and 200 described so far. It will be possible to further narrow the gap (T) between the suction hole (120) of the suction roll (130).

Therefore, as shown in FIG. 14A, the gap (T) between the suction opening 112 and the suction opening hole 120 of the suction roll 300 due to the bending portion 310 of the bending suction pipe 110 inside the suction roll 130 ) Is significantly narrower than the other steel sheet transfer rolls 100 and 200 in the front, so, for example, the suction opening 112 is located adjacent to the suction hole 120, so that the foreign material suction force is not present even without the diaphragm member 150 described above. This will remain stable.

At this time, the bending suction pipe 110, if the reinforcement ribs 170 are provided on the inner surface of the suction roll 130 described above will be adjusted to the degree of bending so as not to interfere with them.

Alternatively, as shown in FIG. 14B, it may be possible to install the diaphragm member 150 surrounding the suction opening 112 of the suction pipe 110 on the bent suction pipe 110.

Also in this case, since the interval T between the suction opening 112 and the suction hole 120 is narrowed, the internal suction concentration space 132' of the diaphragm member 150 decreases, and the steel sheet transfer roll with different foreign material suction ability ( 100) (200).

On the other hand, even in the case of the bent suction pipe 110 of FIG. 14, it is possible to rotate the suction pipe 110 in connection with the driving means 210 described above, and in this case, the suction opening 112 or/ And it is possible to mechanically control the position of the diaphragm member 150 surrounding it.

Next, FIGS. 15 to 17 show a steel sheet transfer roll 400 according to another embodiment of the present invention. Of course, the same components of the steel sheet transfer roll described above are shown by the same reference numerals and the detailed description is brief.

For example, as shown in Figures 15 to 17, the steel sheet transfer roll 400 of another embodiment of the present invention, a plurality of suction openings provided at regular intervals in the circumferential direction of the suction pipe (110) It may be based on the suction opening and closing means 402 to communicate only at least one suction opening 112 selected from among.

For example, the suction opening opening and closing means 402 is provided to be rotatable through the second driving means 420 inside the suction pipe 110 while being spaced at a constant interval in the circumferential direction of the suction pipe 110. The second suction pipe 410 may be provided with a second suction opening 412 communicating with at least one of the suction openings 112 arranged at a (set interval).

That is, in the case of the steel sheet transport roll 400 according to another embodiment of the present invention, the suction roll 130 having the suction pipe 110 and the suction hole 120 and the diaphragm member 150 are the steel sheet transport roll 100 described above. ) (200) (300).

However, in the present embodiment, the suction opening 112 provided in the suction pipe 110 is arranged in a plurality of (prepared heat) at a predetermined interval in the circumferential direction of the suction pipe 110, and the diaphragm member ( A plurality of 150) are also disposed.

Therefore, the suction openings 110 arranged in the circumferential direction of the suction pipe 110 at predetermined intervals, according to the rotation of the second suction pipe 410, only the selected suction opening 112 is the second suction pipe ( The dust collecting force may be applied in communication with the second suction opening 412 of 410, which in turn will allow adjustment of the foreign matter suction path.

That is, in the case of the steel sheet transport roll 400 according to another embodiment of the present invention, according to the rotation of the second suction pipe 410 to which external dust collecting force is applied, the second suction opening of the second suction pipe 410 ( 412) -> suction opening 112 of the suction pipe 110 -> a series of foreign material suction paths of the diaphragm member 150 is implemented so that the foreign material is sucked only in a desired path.

Meanwhile, as illustrated in FIG. 15, one side of the suction pipe 110 may be connected to the outer dust collecting line 20 via a coupling 22 while being fixed to the outer frame 30, and the suction pipe ( The other side of 110) is also fixed to the outer frame 30, the other side of the second suction pipe 410, which is rotated inside and protrudes more than the suction pipe 110, is an external dust collecting line via a rotary joint 24 (20).

Therefore, as the dust collecting force is applied through the dust collecting line 20 connected to one side of the suction pipe 110 and the other side of the second suction pipe 410, suction of the surface of the steel sheet or the surrounding foreign matter S may be performed.

Meanwhile, as illustrated in FIG. 15, the second driving means 420 enabling rotation of the second suction pipe 410 is driven as a driving motor 422 connected to the outer frame 30. It may include a driving gear 424, and a driven gear 426 engaged with the driving gear and provided on the other side of the second suction pipe 420.

Alternatively, although not illustrated in a separate drawing, a chain driven as a driving motor connected to the outer frame 30 is fastened and may include a sprocket provided on the other side of the suction pipe.

Therefore, according to the operation of the gear-side drive motor 422 or the chain-side drive motor of the second drive means 420, the second suction pipe 420 rotates inside the suction pipe 110 and sucks in communication with each other. The suction force through the opening 112 and the second suction openings 412 is popular in the inner suction concentration space 132 ′ of the diaphragm member 150 so that foreign matter can be suctioned.

For example, as shown in FIG. 16, when the steel sheet 10 enters the upper side of the transfer roll 400, the suction opening 412 of the second suction pipe 410 is a circumferential suction opening of the suction pipe 110 ( Among the 112), the position control may be performed through the second driving means 420 described above to communicate with the upper suction opening 112.

Conversely, as shown in FIG. 17, when the steel sheet 10 enters the lower side of the transfer roll 400, the suction opening 412 of the second suction pipe 410 is the circumferential suction opening 112 of the suction pipe 110. To communicate with the lower suction opening 112 of the above, the position may be controlled through the second driving means 420 described above.

That is, in the case of the steel sheet transfer roll 400 of another embodiment of the present invention, the suction pipe 110 is provided as a fixed body, but the inner second suction pipe 420 is provided as a rotating body, so that the suction opening 112 ) And the second suction opening 412 communicate with the foreign material suction path depending on the position.

The steel sheet transfer roll 400 according to another embodiment of the present invention rotates only the second suction pipe 410 inside the suction pipe 110, so that it is possible to facilitate the maintenance of the equipment and the second small diameter. Since only the rotation of the suction pipe 410 is controlled, it will enable a very rapid facility reaction.

More preferably, referring to FIG. 10, as shown in FIG. 15, the gear-side driving motor 422 or the chain-side driving motor (not shown) provided in the second driving means 420 includes a control unit C. Can be linked.

In addition, the control unit (C) may be associated with information (dotted line) or the camera 40 for measuring the occurrence of foreign matters on the transfer roll entry position of the steel sheet 10.

Accordingly, the control unit C controls the rotation angle of the second suction pipe 410 linked through the control of the driving motor of the second driving means 420 in response to the steel sheet conveying environment or the foreign matter generation (scattering) environment. can do.

This is, eventually, through a control unit through the foreign matter suction path through communication between at least one of the suction openings 112 formed in the circumferential direction of the suction pipe 110 and the second suction opening 112 of the second suction pipe 410. It will automatically be controllable.

In this case, it will enable a more optimal intake of foreign substances while responding to the surrounding environment quickly.

Accordingly, the steel sheet transfer rolls 100, 200, 300, 400 of various embodiments of the present invention described so far are various types of foreign matters such as scale, dust, powder, or contaminants such as oil or cleaning solution. It will make the suction removal very effective.

Particularly, while the existing suction rolls are small-diameter suction rolls that are only in line contact with the steel sheet, the steel sheet conveying roll of the present invention is completely used as a conventional deflector roll or bridle roll in a conveying environment of a wide hot or cold rolled steel sheet Will make it possible to use it.

After all, the present invention is a form in which a foreign substance removal function is added in addition to the conveyance guide of the steel sheet, so that there is no need for related facilities such as an existing dust collecting hood, and effectively removes defect factors of the steel sheet product generated in the steel sheet conveying environment.
