At this time, the crop (C) formed on the slab (S) is cut by the cutting device (40). Here, the crop C may be the front end of the casting connected to the dummy bar head. At this time, a burner may be used as the cutting device 40.

Then, the cut crop C is dropped by the crop car 50 and transported. At this time, the crop car (50) can move in a direction perpendicular to the plane of the feed (S). The slab S on which the crop C has been cut is conveyed along the conveying roller table 60 provided with the rollers 61. The cut crop C is dropped on the crop car 50, And can be transported to the outside through the car 50.

2, the crop car 50 moves along the rail 72 by orbital movement of the wire 71 wound on the drum 70. As shown in FIG. The magnet C is accommodated in the cog car 50 by the magnet port 80 and is moved to a cog box (not shown).

When cutting the crop (C) by the cutting device (40), a cutting phenomenon occurs. The cut tongue is separated from the running rail 72 of the crop car 50 and fused and grows. This causes a problem that the crop car 50 can not be positioned at a proper position to receive the crop C.

In addition, the cutting of the rail 72 may additionally cause a problem of releasing the crop car 50 when the crop car 50 is traveling.

On the other hand, the cut crop C can be safely secured to the crop car 50, as shown in Fig. As a result, the feed of the billets S is interfered with, and quality defects of the billets S can be generated. Further, the incompletely seated Crop (C) may cause the continuous casting operation to stop, thereby reducing the productivity.

Hereinafter, the specific control relationship of the control unit 1000 will be described with reference to the respective components.

The first guide part 100 and the second guide part 200 may be spaced apart from each other. Accordingly, a spacing space S1 (see FIG. 4) may be provided between the first guide portion 100 and the second guide portion 200. As shown in FIG. The first guide part 100 and the second guide part 200 are disposed on the movement line of the slab S and can guide the cut crop C to the first roller 310. [

The first guide portion 100 can guide the fall of the cut crop C. At this time, the first guide unit 100 may be disposed on the shifting roller table 30 side.

5, the upper end of the first guide part 100 may be bent in a direction opposite to the conveying direction of the bill S, as shown in FIG. Accordingly, the falling droplet S can be guided to the spacing space S1 by the upper end of the first guide portion 100 bent at a predetermined curvature.

The elevating device 400, the turning part 500, and the plurality of sensors 600 may be disposed below the upper end of the bent first guide part 100. The upper end of the bent first guide part 100 can protect the elevating device 400, the turning part 500 and the plurality of sensors 600 from the cuts generated by the cutting device 40 have.

As shown in FIG. 5, a first hole 110 may be formed in the first guide part 100. Accordingly, the first roller 310 pivoted by the pivoting part 500 can be deployed horizontally in the spacing space S 1 through the first hole 110. Here, the first hole 110 may be vertically long in correspondence with the shape of the first roller 310.

The second guide portion 200 can guide the drop of the cut crop C. At this time, the second guide unit 200 may be disposed on the conveying roller table 60 side.

5, the upper end of the second guide part 200 may be bent in the conveying direction of the slab S, as shown in FIG. Accordingly, the crop S that has fallen and is incompletely seated on the first roller 310 can be guided to the spacing space S1 by the upper end of the second guide portion 200 bent at a predetermined curvature.

The roller unit 300 may be disposed on the lifting device 400 so as to be lifted and lowered by the lifting device 400.

The roller unit 300 may include a first roller 310, a first driving unit 320, and a first power transmitting unit 330. The first driver 320 may be controlled by the controller 1000.

As the roller unit 300 is lifted and lowered by the lifting device 400, the first roller 310 can be lifted and lowered. For example, in a state where the first roller 310 is spread horizontally in the spacing space S1 through the first hole 110, the first roller 310 moves up and down the impact of the dropped crop C So that the crop C placed on the first roller 310 is lowered and then rotated to feed the crop C to the roller table 800.

At this time, since the first roller 310 is provided in the shape of a cylinder, the cutting roller flows along the outer circumferential surface of the first roller 310 even when the first roller 310 is spread in the horizontal direction. Accordingly, it is possible to prevent the cutting roller from being welded to the first roller 310.

The first roller 310 may be rotated by the first driving unit 320. At this time, the rotational speed of the first roller 310 can be accelerated or decelerated by the first power transmitting portion 330. Here, a motor may be used as the first driving unit 320, and a gear unit may be used as the first power transmitting unit 330.

7 and 8, a plurality of first rollers 310 may be disposed, and the first power transmission portion 330 may be configured to enable separate driving or full driving of the first roller 310 can do.

The elevating device 400 may include a frame 410, an elevating part 420, and an elevating member 430.

The frame 410 guides upward and downward movement of the lifting unit 420, which is lifted and lowered by the lifting member 430. Accordingly, the roller unit 300 installed in the elevating unit 420 also moves in conjunction with the upward / downward movement of the elevating unit 420.

7 and 8, the frame 410 may include a pair of guide plates 411 spaced apart from each other and a cover 412 covering the upper portion of the guide plate 411. At this time, the guide plate 411 guides the up-and-down movement of the lifting unit 420. For example, the guide plate 411 may have a pair of first protrusions 411a facing each other. Here, the first projection 411a guides the movement of the elevating part 420, and prevents the elevating part 420 from being displaced in the horizontal direction (x direction). For example, the horizontal section of the first protrusion 411a may be triangular but is not limited thereto.

The cover 412 can be disposed on the upper side of the guide plate 411, as shown in Fig. Accordingly, the cover 412 prevents the lift portion 420 from being deviated to the upper side.

The roller unit 300 may be installed in the lift unit 420. Further, the elevating portion 420 can be raised and lowered by the elevating member 430. Here, as the elevating member 430, a hydraulic cylinder and an air cylinder may be used, but the present invention is not limited thereto, and a motor, a rack, and a pinion may be used. Referring to FIGS. 7 and 8, the elevating member 430 may be disposed on the frame 410.

7 and 8, the elevating unit 420 includes a main body 421 which is moved up and down by an elevating member 430, a supporting unit 422 disposed on the main body 421, and a sensing member 423 .

7, the main body 421 includes a pair of vertical plates 421a spaced apart from each other in the width direction (y direction), a horizontal plate 421b disposed between the vertical plates 421a, A second projection 421c projecting outward in the width direction (y direction) in the vertical plate 421a, a V-shaped roller 421d and a V-shaped roller 421d rotatably arranged on the second projection 421c, And a fixing member 421e for preventing the detachment of the fixing member 421e. Here, an O-ring can be used as the fixing member 421e.

The vertical plate 421a is raised and lowered by the elevating member 430. At this time, since the V-shaped roller 421d is coupled to the first protrusion 411a of the guide plate 411, the vertical plate 421a can move up and down without detaching.

Meanwhile, the main body 421 may include a second hole 421f formed such that the support portion 422 is rotatably disposed.

The support portion 422 may be rotatably disposed in the second hole 421f of the main body 421. [ Accordingly, the support portion 422 can be rotated at a predetermined angle by the rotation portion 500. [

The support portion 422 may include a hinge portion 422a, a shaft 422b provided through the hinge portion 422a, a support plate 422c formed to protrude from the hinge portion 422a, and a protrusion piece 422d .

The hinge portion 422a can be rotatably disposed on the shaft 422b. The shaft 422b may be disposed in the second hole 421f.

The roller unit 300 may be disposed on the support plate 422c. In detail, the first driving unit 320 and the first power transmitting unit 330 of the roller unit 300 may be disposed on the support plate 422c.

On the other hand, the rotary part 500 may be disposed on one side of the protruding piece 422d. That is, one side of the rotary part 500 is disposed on the horizontal plate 421b of the main body 421, and the other side is disposed on the projecting piece 422d.

Therefore, the projecting piece 422d is rotated by the rotation unit 500 on the basis of the shaft 422b. Accordingly, the support plate 422c rotates, and the first roller 310 of the roller unit 300 rotates at a predetermined angle in association with the support plate 422c. Here, as the rotary part 500, an air cylinder or a hydraulic cylinder may be used.

The plurality of sensors 600 can sense the elevated position of the first roller 310. For example, the sensor 600 may be disposed on the guide plate 411 in a vertical direction (z direction).

The sensor 600 senses the sensing member 423 disposed on one side of the main body 421 and transmits a signal including information on the ascending / descending position of the ascending / descending unit 420 to the controller 1000. Accordingly, the control unit 1000 can determine the position of the first roller 310 of the roller unit 300 disposed in the elevation unit 420. The sensor 600 may be an infrared sensor, but is not limited thereto. For example, a touch sensor touching the sensing member 423 may be used.

8, the sensor 600 may include a first sensor 600a, a second sensor 600b, and a third sensor 600c that are vertically spaced apart from the guide plate 411 .

The first sensor 600a serves as an upper limit at the time of the rise. For example, when the sensing member 423 is sensed by the first sensor 600a, the control unit 1000 controls the elevating member 430 to restrict the elevating unit 420 from rising.

Accordingly, when the first roller 310 is positioned at the position corresponding to the first sensor 600a, the crop C can be seated with the minimum impact on the first roller 310. [

The second sensor 600b is located between the first sensor 600a and the third sensor 600c. The position of the first roller 310 corresponding to the second sensor 600b is a reference position, and the first roller 310 at the reference position can be rotated by the rotation unit 500. [ Here, at the reference position, the first roller 310 can be rotated by the rotation unit 500 to a home position in which the first roller 310 is vertically spread and a standby position in which the first roller 310 is vertically disposed.

 The third sensor 600c serves as a lower limit at the time of descent. For example, when the sensing member 423 is sensed by the third sensor 600c, the control unit 1000 controls the ascending / descending member 430 to limit the descent of the ascending / descending unit 420.

Accordingly, when the first roller 310 is positioned at the position corresponding to the third sensor 600c, the crop C can be transported by the rotation of the first roller 310. [

The nozzle 700 can cool the cut crop C by spraying cooling water. To this end, a hose (not shown), a pump (not shown) and a cooling water tank (not shown) arranged to supply cooling water may be disposed at one side of the nozzle 700.

The nozzle 700 may be disposed on the lower side of the first guide part 100 or the second guide part 200. Accordingly, when the first roller 310 on which the crop C is seated is positioned at a position corresponding to the third sensor 600c, the controller 1000 controls the cooling water to the crop C through the nozzle 700 It can be sprayed.

The roller table 800 can be transported by the rotation of the first roller 310 descended by the lifting device 400. [ Accordingly, the roller table 800 can be disposed on the transfer line of the cut crop C.

Referring to FIG. 5, the roller table 800 may be disposed between the first guide portion 100 and the second guide portion 200.

As shown in FIG. 5, the crop C can be cut in two feed lines, and the roller table 800 is provided with a first roller table 800a and a second roller table 800b . The first roller table 800a and the second roller table 800b may be spaced apart from each other and between the first roller table 800a and the second roller table 800b, 310 may be disposed. For example, the first roller table 800a may be disposed between the first guide part 100 and the second guide part 200. [ However, the second roller table 800b may be disposed adjacent to one side of the first guide part 100 and the second guide part 200, but is not limited thereto.

The roller table 800 conveys the crop C fed according to the rotation of the first roller 310 to a crop box (not shown).

The roller table 800 may include a plurality of second rollers 820 disposed on the table 810 and the table 810. [ The rotation of the second roller 820 can be controlled by the control unit 1000. [ For example, the roller table 800 can rotate the second roller 820 using a second driving unit (not shown) such as a motor, a second power transmitting unit 330, and the like. Here, the second power transmission unit may accelerate or decelerate the rotation speed of the second roller 820, and the second driving unit may be controlled by the control unit 1000.

Accordingly, as the first roller 310 of the roller unit 300 descended by the lifting device 400 rotates, the crop C can be conveyed to the roller table 800. [ Then, the roller table 800 transports the crop C to the crop box.

The sensing unit 900 may sense the crop C. Then, the sensing unit 900 transmits a sensing signal to the control unit 1000 as the sensing unit 900 senses the crop C.

The sensing unit 900 may be divided into a first sensing unit 900a and a second sensing unit 900b depending on the position in which the sensing unit 900 is disposed. As the first sensing unit 900a and the second sensing unit 900b, an infrared sensor may be used, but the present invention is not limited thereto.

The first sensing unit 900a senses a crop C that is seated on the first roller 310.

The first sensing unit 900a may be disposed above the first guide unit 100 or the second guide unit 200. FIG.

Accordingly, when the first sensing unit 900a senses the crop C, the control unit 1000 sends a sensing signal to the controller 1000. The controller 1000 controls the elevating member 430 based on the sensing signal, (310). Accordingly, the cast strip S from which the crop C has been removed can be supported and supported by the bent upper ends of the first guide portion 100 and the second guide portion 200.

The second sensing unit 900b can sense the crop C conveyed by the second roller table 800b.

Referring to FIG. 5, the second sensing unit 900b may be disposed above the second roller table 800b. Accordingly, the second sensing unit 900b senses the crop C conveyed along the second roller 820 of the second roller table 800b.

Accordingly, when the second sensing unit 900b senses the crop C, the controller 1000 transmits a sensing signal to the controller 1000. The controller 1000 controls the elevating member 430 and the swing unit 500 based on the sensing signal, Can be controlled. For example, when the first roller 310 rotates and the second sensing unit 900b does not sense the crop C, the controller 1000 controls the elevating member 430 so that the first roller 310 rotates to the second And raises the first roller 310 to the corresponding position of the sensor 800b. Then, the control unit 1000 controls the rotation unit 500 to rotate the first roller 310 from the home position to the standby position. At this time, the rotation of the second roller 820 can be stopped by the control unit 1000.

Hereinafter, the arrangement position of the first roller 310 and the driving according to the rotation of the first roller 310 will be described with reference to FIGS. 9 to 13.

9 (a) is a view showing the standby position of the first roller by the pivoting portion, and Fig. 9 (b) is a view showing the position Fig. 7 is a view showing a groove position of the first roller by the eccentric portion. 10 is a view showing the standby position of the first roller of the crop conveying apparatus according to the embodiment, and Fig. 11 is a view showing the groove position of the first roller of the crop conveying apparatus according to the embodiment.

As shown in Figs. 9A and 10, the first roller 310 may be disposed at a standby position in which the first roller 310 is disposed downwardly by the pivoting portion 500. In detail, the rotary part 500 can rotate the support plate 422c to a standby position in which the axis C1 of the first roller 310 is arranged in the vertical direction (z direction).

Accordingly, since the first roller 310 at the standby position is disposed at the lower portion of the bent upper end of the first guide portion 100, the first roller 310 is not damaged by the cutting. In addition, even if the foreign matter falls into the spacing space S1, the first roller 310 can be prevented from being damaged by an external force due to the foreign matter.

At this time, heat is not emitted from the burner 41 of the cutting device 40. Therefore, in the cast slab S, the crop C may not be separated.

9B and 11, the first roller 310 may be disposed at the home position P1 which is horizontally deployed in the spacing space S1 by the pivoting portion 500 have. At this time, the axis C1 of the first roller 310 may be developed in the conveying direction of the slab S. In detail, the rotary part 500 can rotate the support plate 422c to the home position Pl where the axis C1 of the first roller 310 is arranged in the horizontal direction. Here, the home position P1 is a position of the first roller 310 corresponding to the second sensor 600b, and the second sensor 600b senses the sensing member 423 to detect the position of the first roller 310 .

Here, the rotation of the first roller 310 can be performed in a state where the slice S is paused while the slice S is left with a predetermined width interval. Accordingly, the first roller 310 is not damaged by the cutting surface.

At this time, the seating position P2 may be a position where the cut crop C is seated on the first roller 310. [

When the first roller 310 is located at the seating position P2, the cutting device 40 is driven to perform cutting for the width interval left in the slab S. As a result, the crop C falls on the first roller 310 of the seating position P2.

In this case, since the first roller 310 is located at the seating position P2, the impact of the falling crop C can be minimized. At this time, since the upper end of the second guide portion 200 is bent in the conveying direction of the slab S, the drop S is incompletely seated on the first roller 310 can be guided to the spacing S1 have.

Furthermore, the first sensing unit 900a senses the crop C that is seated on the first roller 310, and can transmit a signal to the control unit 1000. [ Accordingly, the control unit 1000 can lower the first roller 310 by controlling the elevating apparatus 400.

It can be lowered from the seating position P2 to the feeding position P3 by the lifting device 400, as shown in Fig. The conveyance position P3 is a position of the first roller 310 corresponding to the third sensor 600c and the third sensor 600c senses the sensing member 423 to detect the position of the first roller 310 . At this time, the feeding position P3 may be a position where the first roller 310 is disposed in parallel with the second roller 820 of the roller table 800. [ The feeding position P3 may be a position in which the axis C1 of the first roller 310 and the axis C2 of the second roller 820 are arranged in parallel in a plane.

When the first roller 310 is positioned at the feeding position P3, the controller 1000 can cool the cut crop C by spraying the cooling water through the nozzle 700. FIG.

The control unit 1000 controls the first driving unit 320 to rotate the first roller 310 to feed the cooled crop C to the roller table 800. The second roller 820 of the roller table 800 is rotated by the second driving unit to feed the crop C to the crop box.

When the second sensing unit 900b senses the crop C conveyed along the second roller tab 800b, the controller 1000 controls the first roller 310 and the second roller 820 The rotation can be stopped.

The control unit 1000 controls the elevating device 400 to move the first roller 310 from the feeding position P3 to the home position P1. Then, the control unit 1000 controls the rotation unit 500 to rotate the first roller 310 to the standby position.
