The present invention takes a high speed after the rolling process in a hot state and guides the strip safely to the winding machine so that the tip of the entering strip hits the entry guide of the winding machine to close the upper and lower pinch roll gaps. The present invention relates to an induction device of a strip end portion of an entry guide, which can prevent mis-rolling caused by failure.                         

In general, the strip to be produced in the form of hot rolled coil has a high speed (up to 1300 m / min) by ROT (Run Out Table (2)) after passing through the finishing mill in a hot state as shown in FIG. It is taken and guided to the entry guide 4 of the winder.

At this time, the tip of the strip which is guided at high speed by ROT (Run Out Table (2)) will be heard by the feeding speed, and the tip of the strip will be inclined (5) of the entry guide (4). Guided by) will be transferred between the upper, lower pinch roll (6).

In addition, the strip fed to the upper and lower pinch rolls 6 through the entry guide 4 is guided to the mandrel by the upper and lower pinch rolls 6 which rotate at the synchronous speed and the entry speed of the strips. At the same time, it is wound at a high speed to take the form of a hot rolled coil.

However, the strips that are guided by the entry guide while being conveyed at high speed and transferred to the upper and lower pinch rolls have caused various problems in this process.

If you list them in order, they are as follows.

First, the entry guide can't effectively guide the fast-entering strip with the tip lifted up, so it can frequently cause problems such as miss rolls that entangle or pinch the entering strip at the bottom of the entry guide. There was a problem that caused a huge disruption to the operation and resulting economic losses.

Second, there is a problem of causing a problem that the stagnant strip is stagnated for a long time on the Run Out Table (R.O.T) when the misroll occurs, causing damage to the Run Out Table (R.O.T).

Third, when a miss roll occurs, the operator must climb to the upper part of the run out table (ROT) adjacent to the entry guide and use a hand tool such as a gas cutter to dismantle the strip where the entry is tangled or stuck under this part. There was an uncomfortable and unsafe problem.

Fourth, coils produced through normal operation after the completion of the misrolling process because a large amount of strip debris is pinched or finely pinched on the ROT (Run Out Table) and the upper and lower pinch rolls when misrolling occurs or dismantled. There was a problem such as adversely affecting the product .

The present invention has been made in view of the conventional problems as described above, the object of the present invention is to take a high speed after the rolling process in a hot state to take a high speed to guide the strip to enter the winder, the leading end of the strip to enter A strip induction device of the entry guide strip which prevents mis-rolling caused by not hitting the entry guide of the winding machine and failing to pass through the upper and lower pinch roll gaps.

Is a plan view showing the configuration of the strip leading end guide device of the entry guide according to the present invention.

As shown in the drawing, the guide frame 14 having a plurality of hinge holes 16 having equal intervals is provided at an inner side of an open lower portion of the entry guide 10, and the guide frame 14 The upper portion of 14) is provided with an air cylinder 18 to move it up and down by selection.

In addition, the hinge hole 16 of the guide frame 14 is provided with a main hollow shaft 22, which is provided with several installations so as to have three sets of guide supports 20 on the outer side at equal intervals. In addition, the main hollow shaft 22 is connected to the other side of the drive shaft 26 of the universal joint type, which is connected to the drive motor 24 provided on the outside of the entry guide 10. The main shaft 28 in which the gear part 30 is formed except the fixed part on both sides is fixedly fixed at the center in the inside of the head.

In addition, the outer side of the main hollow shaft 22 in which the main shaft 28 is installed is engaged with the gear unit 30 of the main shaft 28 through several planetary gears 34. The several sprockets 36 provided with the auxiliary shaft are connected to drive the chain 40 which is connected to the guide roller 38 which is rotatably installed at the tip of the guide support 20. (32) Several are installed.

On the other hand, the main shaft 28 that is not connected to the drive motor 24 is connected to the guide frame 14 and the fixing key 42 so as not to take a separate rotation, the drive motor 24 Is formed to transmit the rotational force to take more than twice the strip speed conveyed through the ROT (Run Out Table: 44) to the main hollow shaft 22, the rotational force of the main hollow shaft 22 Guide rollers 38 to be interlocked by the rotation is installed by taking the combination of the sprocket 36 and the chain 40 so as to achieve a gear ratio to take the rotation at the feed and synchronous speed of the strip. In addition, a camera (not shown) is installed at the side of the entry guide 10 so as to display the lower state of the entry guide 10 to a worker.

Referring to the accompanying drawings, the operation of the present invention configured as described above and the working relationship generated during this process will be described in detail as follows.

Figure 6 is a schematic diagram showing the operating state of the strip leading end guide device of the entry guide according to the present invention.

First, when the operation of the present invention is schematically described, when the strip is transported to the lower portion of the entry guide 10 while the tip is lifted by a run out table (ROT) 44 as shown, It essentially prevents frictional contact between the tip of the strip and the inclined surface 12 of the entry guide 10, and at the same time, the strip tip is adjusted downward to induce the strip to be safely transported to the upper and lower pinch rolls 46. To achieve this.                     

The operation of the present invention for inducing such a strip to be safely transported to the upper and lower pinch rolls 46 by taking such an operation will be described in more detail as follows.

This does not cause interference between several guide supports 20 in which the main hollow shaft 22 is integrally installed on the outside except for the main hollow shaft 22 installed at the rear of the guide frame 14 during driving. The meeting is made by (24).

At this time, the guide support 20, which is integrally rotated with the main hollow shaft 22, rotates at twice the speed of the strip, and rotates at the same speed as the feeding speed of the strip at the tip. Taking the upward state to the guide roller 38, it is possible to take a downward adjustment by taking a strike as if pushing the leading end of the coming strip in the exit direction.

On the other hand, the state that the strip proceeds to the entry guide 10 in this way is always displayed to the operator through the camera installed on the entry guide 10 side.

Here, in the case where it is determined that the main hollow shaft 22 cannot safely guide the upstream end of the strip that is in progress while observing the strip progressing under the entry guide 10 due to a positional defect. The operator may operate the air cylinder 18 to adjust the height of the guide frame 14 in which several main hollow shafts 22 are installed.

This is because the air cylinder 18 is connected to the front end of the cylinder shaft 48 to the upper portion of the guide frame 14 so that when the operator drives the cylinder shaft 48 back and forth, the guide frame 14 is also moved back and forth. Because the connection is installed.

The guide roller 38 rotates the main shaft 28 fixed to the center of the main hollow shaft 22, the gear 30 and the planetary gear 34 of the main shaft 28. It is made by several auxiliary shafts 32 engaged with each other.

That is, when the main hollow shaft 22 is rotated in one direction by the drive motor 24, several auxiliary shafts 32 moving in the same direction as the main hollow shaft 22 are the main shaft 28. The rotation is performed at the same time as the planetary gear 34 engaged with the gear unit 30 of).

And, thus moving simultaneously with the secondary shaft 32 which takes the rotation is thereby such as taking a cycle, which rotates the sprocket 36, which is installed at the same time, this chain takes a pivoting the sprocket 36 that is installed connected 40 is orbitally rotated, and the chain 40 being orbitally rotated rotates the guide roller 38 rotatably installed at the tip of the guide support 20.

Therefore, the guide roller 38 is able to take the operation as described above and take its own rotation without a separate drive means.

On the other hand, the guide frame 14 exposed to the lower portion of the entry guide 10 is installed in the main hollow shaft 22 from the front to the rear step by step, and the front end is entered in various forms In response to the tip of the coming strip it is possible to achieve the action that can be guided safely.

As described above, the present invention has a strip leading end induction device of the entry guide which takes a high speed after being rolled in a hot state and guides the strip safely to the winding machine so that the leading edge of the entering strip is the entry guide of the winding machine. It is possible to prevent the mis-rolling phenomenon that does not pass through the upper and lower pinch roll gaps by hitting the. There is an effect that can fundamentally prevent work delays, unsafe and unsafe problems in dismantling, and problems that cause high temperature miss roll strips to stagnate on the plant and thus adversely affect the installation (life shortening, deterioration). have.
