Referring to FIG. 1, in the hot rolling process of a steel mill, the finishing mill (R) transfers the raw material (S) to a post process through a feed roller unit 100 after the final rolling of the raw material (S) to be rolled.

The feed roller unit 100 is rotated according to the material extraction speed of the last stand of the finishing mill R, and the material S is wound up in a winding machine (not shown) through the pinch roll P and finally into the hot rolled coil. Produced.

1 to 3, 9, the material conveying apparatus 1 according to an embodiment of the present invention is a feed roller 100, side guide portion 200, position measuring unit 300, the control unit ( 400).

The feed roller part 100 transfers the raw material S rolled by the finishing mill R to a later process. The conveying roller part 100 includes a conveying roller 110, a conveying motor 111, and an electromagnet part 112.

One end of the feed roller 110 is disposed on the left side when the outer side of the first side guide 210 is based on FIG. 2, and the other end is disposed on the right side of the second side guide 220. The feed motor 111 is connected to one end of the feed roller 110 to provide a rotational force to the feed roller (110).

2, 4 and 5, the electromagnet portion 112 is provided in the feed roller 110, and corrects the deflection transfer of the material (S).

A plurality of electromagnet parts 112 are provided in a row in the feed roller 110 along the width direction of the feed roller 110 (see FIG. 4). The operation of the electromagnet portion 112 is made individually according to the conveying direction of the material (S). That is, the position of the electromagnet portion 112 operated according to the deflection direction and the degree of the material (S) is changed.

The electromagnet unit 112 generates an electromagnetic force under the control of the controller 400, and consists of an iron core core and a coil surrounding the same. The configuration of the electromagnet portion 112 is general and a detailed description thereof will be omitted.

The electromagnet portion 112 is disposed in the plurality of feed rollers 110 at the same rotation angle interval with respect to the center of rotation of the feed roller 110 (see Fig. 5). In the present embodiment, the electromagnet portion 112 is disposed on the feed roller 110 at intervals of 90 degrees rotation angle. Therefore, due to the rotation of the feed roller 110, the one side of the electromagnet portion 112 is relatively far from the material (S), the other side of the electromagnet portion 112 is relatively close to the material (S) material (S) It can be provided to the electromagnetic force continuously to achieve the correction of the material (S).

Side guide portion 200 is located on the upper side of the feed roller 100, guides the transfer of the material (S). The side guide part 200 includes a first side guide 210 and a second side guide 220.

The first side guide 210 is located at the left end side of the feed roller 110, and includes a first slope guide 210a and a first parallel guide 210b. The second side guide 220 is located at the right end side of the feed roller 110 and includes a second inclined guide 220a and a second parallel guide 220b.

The first slope guide 210a and the second slope guide 220a are positioned at front ends of the first side guide 210 and the second side guide 220. The first slope guide 210a and the second slope guide 220a guide the entering material S to the center side.

To this end, the interval between the inclined guides 210a and 220a becomes gradually narrower from the front end to the rear end, and the interval between the rear ends of the inclined guides 210a and 220a is equal to the interval between the parallel guides 210b and 220b.

The first parallel guide 210b and the second parallel guide 220b are connected to the rear ends of the first slope guide 210a and the second slope guide 220a, respectively. In this embodiment, the inclined guides 210a and 220a are hinged to the parallel guides 210b and 220b. Therefore, the inclination guides 210a and 220a may adjust the inclination angles with the parallel guides 210b and 220b by a cylinder (not shown) installed at one side.

The position measuring part 300 is located in front of the side guide part 200. The position measuring unit 300 measures whether the raw material S rolled and fed by the finishing mill R enters the center of the feed roller 100.

That is, the position measuring unit 300 measures the position in the width direction of the workpiece S to measure whether the workpiece S enters the center of the feed roller 100 or is deflected in one direction.

When it is determined that the workpiece S enters in one direction by the position measuring unit 300, the electromagnet unit 112 is operated through the controller 400 to correct the deflection of the workpiece S.

The plurality of feed rollers 110 having the electromagnet portion 112 are disposed in front of the parallel guides 210b and 220b. According to the present embodiment, a plurality of feed rollers 110 having the electromagnet part 112 are disposed between the position measuring part 300 and the parallel guides 210b and 220b.

Through this, since one side deflection of the material S can be corrected before the material S enters the parallel guides 210b and 220b, damage to the inner surface of the parallel guides 210b and 220b due to the one side deflected material S is achieved. Can be suppressed.

2, 4, and 9, the controller 400 controls the operation of the electromagnet unit 112 based on the measurement signal transmitted from the position measuring unit 300. In detail, the control unit 400 operates the electromagnet unit 112 having a plurality thereof individually according to the conveying direction of the material S to correct the deflection transfer of the material S by the electromagnetic force generated by the electromagnet unit 112. do.

With reference to the drawings will be described the operating principle of the material conveying apparatus according to an embodiment of the present invention.

The raw material S rolled by the finishing mill R is transferred to the post process through the feed roller unit 100. At this time, the side guide portion 200 guides both sides of the material (S) so that the material (S) is stably transferred on the feed roller unit (100). By the side guide part 200, the material (S) is blocked from being separated to the outside of the feed roller 100.

The position measuring unit 300 detects the width direction position of the material S entering the side guide part 200 and corrects it through the controller 400 when the material S is deflected in one direction.

6 and 9, when the position measuring unit 300 detects the exact center transfer of the material S, the position measuring unit 300 transmits this signal to the control unit 400. In this case, since it is not necessary to correct the conveying direction of the material S, the controller 400 does not operate the electromagnet part 112. As a result, the central feed of the raw material S is maintained as it is.

7 and 9, when the position measuring unit 300 detects the left deflection of the material S, the position measuring unit 300 transmits such a signal to the control unit 400. The control unit 400 operates the electromagnet unit 112 based on this to correct the deflection of the material (S). Specifically, the controller 400 operates only the two right electromagnet parts 112 in response to the left deflection of the material S, and pulls the material S to the right by the electromagnetic force generated by the right electromagnet part 112. This corrects the leftward deflection of the raw material S. In this case, the electromagnet part 112 may stop the operation when the material S passes through the electromagnet part 112 to prevent the electromagnetic force from lowering the conveying speed of the material S when the material S is transferred. .

On the contrary, when the position measuring unit 300 detects the right deflection of the material S (see FIGS. 8 and 9), the control unit 400 operates only the left two electromagnet units 112 and the left electromagnet unit 112. By correcting the right deflection of the material (S) by pulling the material (S) to the left with the electromagnetic force generated in the. In this case, the electromagnet part 112 may stop the operation when the material S passes through the electromagnet part 112 to prevent the electromagnetic force from lowering the conveying speed of the material S when the material S is transferred. .
