The transfer unit 30 includes a plurality of rollers, and uses a roller to transfer the metal sheet supplied from the leveling unit 10 from a first position (P1) to a second position (Second Position, P2). Can be transported.

Here, although the transfer unit 30 describes a case in which a roller is used to transfer the thin metal plate, the present invention may not be limited to this. For example, in the present invention, the transfer part 30 may be various, such as a belt type, such as a conveyor belt, and a chain type.

In addition, the first position P1 and the second position P2 described below are arbitrary positions on the factory line and are not limited thereto. For example, when a new portion is added to the metal sheet processing apparatus 1, the first position P1 and/or the second position P2 may be changed.

In FIG. 1, the direction of movement of the transfer unit 30, that is, the direction in which the thin metal plate flows in the process, is indicated as the first direction DR1.

Hereinafter, each part of the thin metal plate processing apparatus 1 will be described in detail with reference to the accompanying drawings.

2 to 3 are views for explaining the loading unit. Hereinafter, a description of the parts described in detail above will be omitted.

Referring to FIG. 2, the loading part 10 includes a motor part (Motor Part) 12 to supply the metal thin plate 100 from the metal thin plate coil 11 in which the metal thin plate 100 is wound in the form of a coil. It may include a rotating axis (13) connected to the driving shaft (Driving Axis) of the motor unit 12. Here, the rotating shaft 13 may be fitted to the center of the thin metal coil 11.

When the rotating shaft 13 is rotated by the motor unit 120, the thin metal coil 11 may rotate while the thin metal coil 100 may be supplied.

The loading unit 10 may rotate a little faster than the traveling speed of the leveling unit 20 so that the unwinding of the metal thin plate 100 proceeds smoothly.

The loading section 10 may be provided with an optical sensor or the like so that the uncoiled metal thin plate 100 does not contact the floor between the loading section 10 and the leveling section 20 to adjust the rotational speed of the rotating shaft.

In addition, the loading unit 10 may further include a height control unit (Level Control Part 14) for adjusting the height of the rotating shaft (13).

The height adjustment unit 14 may move the rotating shaft 13 in the vertical direction (third direction DR3). For example, as shown in FIG. 3(A), the height of the rotating shaft 13 can be set to the first height H1, and then the height of the rotating shaft 13 is raised to the second height H2. I can do it. Of course, it may be possible to move from (B) to (A) of FIG. 3.

The height adjuster 14 may be implemented in a cylinder type. For example, it is possible to implement the height adjustment unit 14 with a hydraulic cylinder.

Here, although an example in which the height adjustment unit 14 is implemented in a cylinder type is described, the present invention may not be limited thereto.

4 to 7 are views for explaining the leveling unit. Hereinafter, a description of the parts described in detail above will be omitted.

The leveling unit 20 may planarize the metal thin plate 100 supplied from the loading unit 10. In other words, the leveling unit 20 may flatly correct the gently bent metal thin plate 100 along the traveling direction (first direction DR1).

To this end, as shown in FIG. 4, the leveling unit 20 includes a base plate (200), an anti-dislocation part (210), a tip part (Tip Part, 220), and a heating unit (Heating) Part, 230).

The base plate 200 may include a portion extending in the first direction DR1 among the horizontal directions.

The base plate 200 may have a sufficiently long length L1 in the first direction DR1. In detail, the length L1 of the base plate 200 in the first direction DR1 may be greater than the length L2 in the second direction DR2, that is, the width.

The metal thin plate 100, as posted in FIG. 5, may be sufficiently gently unfolded while passing the upper portion of the base plate 200.

The departure preventing portion 210 may be formed on both sides of the base plate 200 and may include portions extending in a vertical direction and a third direction DR3.

The detachment preventing unit 210 may prevent the metal thin plate 100 passing through the upper portion of the base plate 200 from being detached from the base plate 200.

The tip portion 220 is disposed on the inlet side of the base plate 200, and the end EP of the metal thin plate 100 can be removed from the metal thin plate coil 11. That is, the metal thin plate 100 is rolled in the form of a coil, the beginning of the metal thin plate coil 11, that is, the end of the metal thin plate 100 is caught by the tip portion 220, the leveling part 20 of the metal thin plate 100 Supply to the furnace can be initiated.

The heating unit 230 may apply heat to the base plate 200.

For example, a heating wire is installed in the base plate 200, and the base plate 200 may be heated by supplying electric power to the heating wire installed in the base plate 200 to the heating unit 230.

When the heating unit 230 applies heat to the base plate 200, the gently bent metal thin plate 100 can be flattened more effectively.

Referring to FIG. 6, the inlet side of the base plate 200 may include a portion 201 that is gradually inclined toward the top in the vertical direction, that is, in the third direction DR3.

In this case, the metal thin plate 100 can be easily brought into close contact with the base plate 200.

The leveling unit 20 may correspond to the metal sheet coil 11 even when the size thereof is changed.

For example, as shown in FIG. 7(A), when the size of the thin metal coil 11 is sufficiently large, the height adjustment unit 14 of the loading unit 10 removes the height of the rotating shaft 13. It can be set to 1 height (H1).

Thereafter, when the amount (length) of the thin metal plate 100 included in the thin metal coil 11 decreases, the size of the thin metal coil 11 may also be reduced.

In this case, as shown in (B) of FIG. 7, the height adjustment unit 14 may set the height of the rotation shaft 13 to a second height H2 higher than the first height H1. Then, even if the size of the thin metal coil 11 is reduced, the portion in which the thin metal coil 100 is discharged from the thin metal coil 11 may correspond to the leveling unit 20.

8 to 9 are views for explaining the transfer unit. Hereinafter, a description of the parts described in detail above may be omitted.

Referring to FIG. 8, the transfer unit 30 may include a plurality of rollers 300 for transferring the metal thin plate 100 supplied from the leveling unit 20 in the first direction DR1.

The plurality of rollers 300 may be arranged at regular intervals in the first direction DR1.

The at least one roller 300 may rotate by receiving power from a power source (not shown).

When the metal thin plate 100 is supplied from the leveling unit 20, the supplied metal thin plate 100 may be transported in the first direction DR1 on a plurality of rollers 300 of the transfer unit 30.

The roller 300 may include a friction part (310) for improving the contact of the metal thin plate (100).

The friction part 310 may have a relatively large surface roughness. In this case, the transfer efficiency of the metal thin plate 100 may be improved.

Meanwhile, the position of the friction part 310 in the roller part 300 may be changed according to the position of the transfer part 30. This will be described with reference to FIG. 9 attached.

Referring to FIG. 9, the friction part 310 includes a first friction part (311), a second friction part (Second Friction Part, 312), a third friction part (Third Friction Part, 313), and a fourth friction It may include a portion (Fourth Friction Part, 314).

The first friction portion 311 and the second friction portion 312 are adjacent to the first end (E1) of the roller 300, and the third friction portion 313 and the fourth friction portion 314 are It may be adjacent to the second end (Second End, E2) of the roller (300).

Here, based on the traveling direction (first direction DR1) of the thin metal plate 100, the distance between the first friction portion 311 and the first end E1 at the rear is referred to as a first distance d1. , It is assumed that the distance between the first friction portion 311 and the first end E1 in the front is the fifth distance d5.

In this case, the fifth interval d5 may be smaller than the first interval d1.

In other words, the distance between the first friction portion 311 and the first end E1 may decrease as the metal thin plate 100 moves in the traveling direction (first direction DR1).

In other words, the first friction portion 311 may move toward the first end E1 toward the traveling direction (first direction DR1) of the metal thin plate 100.

The same may be applied to the second friction portion 312, the third friction portion 313, and the fourth friction portion 314.

As such, as the friction portion 310 moves toward the ends E1 and E2 of the roller 300 as it moves toward the traveling direction (first direction DR1) of the metal thin plate 100, the metal thin plate having a relatively thin thickness ( 100) can be prevented from being crushed in the second direction DR2.

10 to 12 are views for explaining the degreasing unit. Hereinafter, a description of the parts described in detail above may be omitted.

Referring to (A) of FIG. 10, the degreasing unit 40 may remove organic substances from the metal thin plate 100 by spraying the degreasing liquid 410 on the metal thin plate 100. To this end, the degreasing unit 40 may include a plurality of degreasing liquid injection units 400.

The degreasing liquid injection unit 400 may spray the degreasing liquid 410 toward the metal thin plate 100. Then, organic substances such as anti-rust oil, rolling oil, and cutting oil, which are buried on the surface of the metal thin plate 100 by the degreasing liquid 410, or inorganic substances such as debris, abrasives, and dust may be removed.

As the degreasing liquid 410, for example, an alkali degreasing liquid such as sodium hydroxide or sodium metasilicate may be used.

The alkali-based degreasing liquid 410 can neutralize rolling oil or the like applied to the surface of the metal thin plate 10.

In addition, a small amount of surfactant may be added to the degreasing liquid 410 to be used.

The degreasing unit 40 may adjust the temperature, pressure, and input speed of the degreasing liquid 410 while checking the degree of degreasing.

Although not shown, the degreasing unit 40 may further include a degreasing liquid recovery unit for recovering the degreasing liquid 410 sprayed on the metal thin plate 100.

The degreasing unit 40 may spray the degreasing liquid 410 on the warped portion of the metal thin plate 100. To this end, the transfer portion 30 may twist the metal thin plate 100 in a region corresponding to the degreasing portion 40. This will be described in more detail after FIG. 13.

10(B) illustrates twisting in the form of a bar to facilitate understanding of the twisting of the metal thin plate 100.

Referring to FIG. 11, in the region corresponding to the degreasing portion 40, that is, in the first region AR1, the metal thin plate 100 is a portion (a) in which its cross section is horizontal, right side of the cross section of the metal thin plate 100 Part (b) in which the end is inclined at the first angle (θ1) toward the upper part, the right end of the cross section of the metal thin plate 100 is inclined at a second angle (θ2) greater than the first angle (θ1) toward the upper part Part (c), the left end of the cross section of the thin metal plate 100 at a third angle (θ3) toward the top, and the left end of the cross section of the thin metal plate 100 toward the top at a third angle A portion e inclined at a fourth angle θ4 greater than (θ3) may be included.

In other words, the metal thin plate 100 in the first region AR1 may include a portion gradually twisted at a predetermined angle to the left and a portion gradually twisted at a predetermined angle to the right.

In this case, by preventing the degreasing solution 410 injected by the degreasing unit 40 from being concentrated at a specific position of the metal thin plate 100, deformation of the metal thin plate 100 can be prevented and the degreasing effect can be maximized. have.

Referring to FIG. 12, the degreasing liquid injection unit 400 of the degreasing unit 40 is a first degreasing liquid injection unit 401 for spraying the degreasing liquid 410 from the top toward the metal thin plate 100 and a metal thin plate at the bottom. It may include a second degreasing liquid injection unit 402 for spraying the degreasing liquid 410 toward (100).

In this case, the degreasing efficiency of the metal thin plate 100 may be further improved.

Here, only the case where the metal thin plate 100 is distorted in the first region AR1 is described, but the metal thin plate 100 can be distorted in the second region AR2 after the first region AR1. This will be described in more detail later.

The configuration of the transfer part 30 for twisting the thin metal plate 100 will be described below with reference to the accompanying drawings.

13 to 18 are views for explaining the transfer portion for twisting the thin metal plate. Hereinafter, a description of the parts described in detail above may be omitted.

Referring to FIG. 13, the transfer unit 30 may include a torsional part 320 that twists the metal thin plate 100.

The warp portion 320 may include a plurality of rollers 300 having different travel directions.

In other words, the twisting part 320 may be implemented by disposing and arranging at least one traveling direction of the plurality of rollers 300 continuously arranged differently from the traveling direction of other adjacent rollers 300.

For example, as shown in FIG. 13, suppose a case where the warpage portion 320 is formed using a total of 13 rollers 300 (①②③④⑤⑥⑦⑧⑨⑩⑪⑫⑬).

Here, the metal thin plate 100 may be inclined toward one side at one end of the cross section while passing through the ① roller, ② roller, ③ roller, and ④ roller. In other words, the ① roller, ② roller, ③ roller, and ④ roller can make the metal thin plate 100 incline with one end of the cross section upward.

Subsequently, the metal thin plate 100 may return to the inclination again as one end of the cross section inclines toward the bottom again while passing through the ④ roller, ⑤ roller, ⑥ roller, and ⑦ roller.

Thereafter, the metal thin plate 100 may incline the other end of the cross section toward the top while passing through the ⑦ roller, ⑧ roller, ⑨ roller, and ⑩ roller.

Thereafter, the metal thin plate 100 may return to the inclination again as the other end of the cross section inclines toward the bottom while passing through the pin roller, the pin roller, the pin roller, and the pin roller.

As such, the metal thin plate 100 may be distorted by disposing at least one roller 300 in different directions.

Based on these contents, the ② roller, ③ roller, ④ roller, ⑤ roller, and ⑥ roller can be referred to as a left twisting part 320a (or a right twisting part).

In addition, the ⑧ roller, ⑨ roller, ⑩ roller, ⑪ roller, and ⑫ roller may be referred to as a right warp portion 320b (or a left warp portion).

On the other hand, the roller 300 can be rotated, but it is possible to change its direction.

In addition, although not illustrated, it may be possible to further include a roller direction changing unit for changing the traveling direction of the roller 300.

The warping part 320 of the transfer part 30 may further include a guide part (GP). The guide portion GP may guide the inclination of the metal thin plate 100 so that the metal thin plate 100 can be more naturally twisted.

The guide unit GP may include at least one unit guide (UG) (hereinafter, “unit guide” may be referred to as “guide”).

The unit guide UG may include a base bar (BB) and a side guide (SG) as posted in FIG. 14.

The base bar BB may include a portion extending in a direction in which the transfer part 30 travels, that is, a direction intersecting the first direction DR1. The metal thin plate 100 may pass through the upper portion of the base bar BB.

The side guide SG is formed at both ends of the base bar BB, and may include a portion extending in a vertical direction (third direction DR3). The side guide SG can prevent the metal thin plate 100 from being separated.

The unit guide UG may be positioned between two adjacent rollers 300.

The unit guide UG does not rotate like the roller 300, but it is possible to change the direction of progress of the unit guide UG, that is, the direction of the base bar BB to guide the metal thin plate 100.

In addition, although not illustrated, it may be possible to further include a guide direction changing unit for changing the progress direction of the unit guide UG.

A plurality of such unit guides UG may be gathered to form a guide unit GP.

For example, as shown in FIG. 15, suppose that a guide unit GP is formed using a total of 12 unit guides UG (①②③④⑤⑥⑦⑧⑨⑩⑪⑫).

Here, the metal thin plate 100 may be inclined toward one side at one end of the cross section while passing the ① guide, ② guide, and ③ guide. In other words, the guide (1), guide (2), and guide (3) can guide the metal thin plate (100) so that one end of the cross section is inclined upward.

Thereafter, as the metal thin plate 100 passes through the ④ guide, the ⑤ guide, and the ⑥ guide, the one end of the cross section is inclined again toward the bottom, and the inclination can be restored again.

Thereafter, the metal thin plate 100 may be inclined toward the upper side of the other end of the cross section while passing through the ⑦ guide, ⑧ guide, and ⑨ guide.

Thereafter, as the metal thin plate 100 passes through the 이드guide, ⑪guide, and ⑫guide, the other end of the cross-section is inclined toward the lower side, and thus the slope can be restored.
