Description

Device for loading slab crop

The present invention relates to a stacking device for loading the crop of the initial and end slabs generated during the continuous casting operation, and more particularly to a slab crop stacking device that can increase the loading efficiency by stacking the slab crops horizontally.

In general, the sealing part when the cast is drawn out after the dummy bar sealing operation for drawing molten steel at the beginning of continuous casting is called an ultra cast, and the front end is called a head part, and the head of the final casting is solidified to cause a bleeding present due to the drawing force; In order to prevent the phenomenon that the molten steel overflows to the upper part), a part generated in the process of adding a large amount of coolant is called a horse cast and the rear end is called a tail part.

Since the head part and the tail part are not suitable for the slab that the demand demands, the head part and the tail part are partially cut (about 700 mm), and then loaded into the crop box and transferred to the next processing step.

4 is a conventional slab crop loading apparatus, the head and tail crops 150 cut from the torch cutting machine are seated on the crop transport car 100, and the crop transport car 100 drives a wire and a wire drum. The motor is moved to the crop pushing device 110 by the motor, and the pusher 111 pushes the crop 150 placed on the crop feeder 100 according to the operation of the cylinder installed at the rear of the crop pushing device 110. It is to drop to the crop box 130 through the inclined surface of the crop guider 120 located in front of the transfer car 100.

However, the above-described conventional structure has a lower portion supporting the crop box as the crop is loaded while colliding with the inner surface of the crop box while the crop is dropped along the inclined surface of the crop guider. There is a problem that the crop box is gradually inclined to maintain a constant horizontal plane due to the breakage of the cement structure.

Therefore, when changing the crop box, it is not possible to properly hook the crop box transfer hook to the lugs installed on both sides of the inclined crop box, thereby preventing the crop box from being replaced, which causes the processing time of a subsequent process to increase.

In addition, the stacking method due to the crop drop causes the crops to be irregularly stacked inside the crop box, so it is loaded less than the amount that can be loaded, and thus, frequent crop box replacement is required, and the life of the crop box is reduced by the impact of the crop. There is this.

Accordingly, the present invention has been made in order to solve the above problems, in the apparatus for loading the tail crop of the head generated during the playing work to the crop box, the crop loading type in the horizontal stacking method in the crop box constantly It is an object of the present invention to provide a slab crop stacking apparatus capable of increasing the crop load in the crop box and minimizing the number of crop box changes by stacking the stack without impact.

Hereinafter will be described the operation of the present invention.

When the crop box 10 is placed on the cement structure 20 at the bottom of the facility and is in the loading standby state, the vertical cylinders 50 on both sides of the crop box 10 are lowered to place the loading plate 12 inside the crop box 10. Is placed on the bottom of the crop box 10 and the driving cylinder 31 and the left and right cylinders 33 and 34 of the pushing unit are also contracted to be in a reversed state.

When the operator starts the operation for loading the crop 150 by operating a switch such as a control panel in the standby state, first, the vertical cylinder 50 is extended and installed at the tip of the piston rod of the vertical cylinder 50. The horizontal plate 51 is raised.

As the horizontal plate 51 rises, the catching plate 13 placed between the guide brackets 52 of the horizontal plate 51 is pulled up along the hole 11 of the crop box 10 and thus the catching plate 13 ) Is attached to the loading plate 12 is lifted to the top of the crop box 10, the top of the crop box 10 and the loading plate 12 to maintain a horizontal state.

Here, the rising position of the horizontal plate 51, that is, the amount of extension of the vertical cylinder 50 is controlled by the sensing sensor 61 installed in the vertical bar, but since the vertical cylinder 50 must be fully extended at the beginning, When the vertical cylinder 50 is extended and the horizontal plate 51 is sensed by the detection sensor 61 until the side of the horizontal plate 51 is detected by the detection sensor 61 located above, the operation of the vertical cylinder 50 is stopped. As described above, the stacking plate 12 has the same height as that of the top of the crop box 10.

Meanwhile, the crop 150 cut by the torch cutting machine is placed on the upper plate 42 on the trolley 41 and then cropped along the rail 40 according to the operation of the step motor 44 installed in the trolley 41. It is moved to the loading position on the side of the box 10.

At this time, the trolley 41 transported along the rail 40 is detected by the detection sensor 47 installed on the side of the trolley 41 at the left detection sensor 48 installed along the rail 40. In response to the signal of the step motor 44 of the trolley 41 stops the operation to position the crop 150 in the left cylinder 33 position.

When the cart 41 stops, the driving cylinder 31 installed on the support 30 is extended in one step, and the crop 150 placed on the upper plate 42 is disposed on the left side of the coupling bracket 32. It is pushed by the push rod 35 of the cylinder 33 and is mounted on the loading plate 12 past the crop box 10 tip.

Here there is a gap between the top plate 42 of the trolley 41 and the tip of the crop box 10, the gap is a top plate 42 by the friction force of the bottom of the crop 150 is pushed by the pusher 35 The guide plate 45 installed in the block box is pushed toward the tip of the crop box 10.

Therefore, the crop 150 is to be safely moved on the loading plate 12 through the guide plate 45 connecting the top plate 42 and the crop box 10 end.

As such, the crop 150 moved to the loading plate 12 by the operation of the driving cylinder 31 in one step is further extended by the pusher 35 while the left cylinder 33 installed in the connecting bracket 32 is extended in two steps. It is moved until it is caught by the stopper 14 installed on the top of the crop box 10 is moved inside.

When the crop 150 is completely transferred to the loading plate 12, the driving cylinder 31 and the left cylinder 33 are contracted to return to their original positions. In addition, as the crop 150 is moved to the loading plate 12, the guide plate 45 withdrawn forward by the friction force of the crop 150 is inside the upper plate 42 by the return force of the inner elastic spring 46. The balance 41 is also returned to the torch cutting machine for the next crop 150 transfer.

On the other hand, when the new crop 150 is seated on the top plate 42, the trolley 41 moves until the sensing piece 47 is detected by the right side sensor 49 to move the crop 150 to the right cylinder 34 position. Will be placed on the

Crop 150 is placed on the stacking plate 12 according to the above-mentioned one-step operation process. This time, the right cylinder 34 is extended in two stages, and is pushed further by the pusher 35 in the second step. 150 will be placed next to.

According to one embodiment of the present invention, the stacking box 10 is made of an inner area into which four crops 150 are inserted, and after two crops 150 are stacked toward the stopper 14 as described above. In the same way, that is, by placing the other two crops 150 on the stacking plate 12 in a one-step operation, it is possible to place the four crops 150 on the stacking plate 12 in a horizontal state .

When all four crops 150 are stacked in a horizontal state, the vertical cylinder 50 is contracted by a predetermined amount to lower the loading plate 12 to the next step. That is, the vertical cylinder 50 is contracted and stopped until the horizontal plate 51 is detected by the second detection sensor 61, thereby lowering the loading plate 12 by one width of the crop 150.

Since the detection sensor 61 is attached to the vertical bar at the same thickness interval as the crop 150, when the loading plate 12 descends to the next detection sensor 61, the top of the crop box 10 and the loading plate The upper surface of the crop 150 placed on the (12) is in a horizontal state.

Therefore, it is possible to move the new crop 150 on the crop 150 loaded on the stacking plate 12 in the same manner as the operation of moving the crop 150 on the first stacking plate 12.

As such, if the crop 150 is continuously loaded, the crop 150 is stacked on top of each other, and thus more crops 150 may be loaded depending on the height of the crop box 10 and the amount of sensing sensors.

When the crop 150 is loaded in the crop box 10, the crop box 10 is replaced by a crane or the like.

According to the slab crop loading apparatus according to the present invention as described above, it is possible to load the crop without impacting the crop box to prevent the damage to the crop box, by stacking the crops to maintain the maximum loading rate, The efficiency of work can be improved by shortening the loading box change interval.
