Description

Movable Banding Machine for Coil

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bending machine for coils, and more particularly, to a movable band fastening device for an outer plate coil, which is rotatable and rotatable, and in which a strap chute is integrated to fasten a band while moving.

In general, hot rolled coils produced by hot rolling are cooled in a cooling atmosphere, and then received a work instruction and sent to a post process using a crane. Here, after the skin pass mill is performed, it is shipped as a finished product or sent to a cold rolling mill, which is the next post-process. After working here, the band is fastened to the outer coil using a stationary banding machine installed on the work line.

However, in the case of the final product (HF material: Hot Final material), which takes up 15% to 20% of the coil produced in the hot rolling mill, the coil is supplied to the binding box by a crane because it is cooled in a cooling atmosphere and then shipped as a finished product. After tightening the band.

In this case, when using a manual device, as shown in FIG. 1C, an operator views the outer diameter data of the coil 100 displayed on the terminal, prepares a material, that is, a band 116, and uses the manual tightener 118. After tightly tightening the band 116 using the manual sealer (Sealer, 120) was used to fasten the band 116.

By the way, when fastening the band by the manual work takes excessive preparation time of the band 116, and because of the manual work, not only the band is not tightly fastened when fastening, but also the band 116 while firmly tightening the band If bounced off, there is a potential risk of a safety accident, and a lot of work time is required.

In addition, since the conventional stationary bending machine is fixedly installed on the production line as shown in FIG. 1A, when the stationary bending machine 200 is applied to the outer coil and used as a bending machine, the temper rolling work is delayed as well as one by one. You have to work on the move.

On the other hand, even if the stationary banding machine 200 is installed in the binding place, since the device is stationary, there is a burden of additionally installing a moving conveyor.

In addition, if the fixed banding machine 200 is simply installed to be retrofitted, there is a problem in that a fixed strap chute 112 as shown in FIG. 1B must be installed for each skid 114, as well as a bending machine. When the band is fastened while moving, there is a problem in that it is very difficult to match the strap chute 70 in the bending machine body with the fixed strap chute 112 installed in the fixed skid 114.

The present invention has been made in order to solve the above problems, can be moved in the binding place for the prevention of safety accidents due to the manual work, shortening the working time and improving work efficiency, it can rotate itself, the strap chute is The present invention is to provide a movable band fastening device for an outer plate coil that can be easily and firmly fastened while being provided integrally and moving to a desired coil position.

Hereinafter, the operation of the apparatus of the present invention having the above configuration will be described with reference to the flowchart of FIG.

First, the final material wound by hot rolling is cooled in a cooling atmosphere and then supplied to a binding site by using a crane to be shipped as a finished product.

Thereafter, the position of the coil 100 is checked as shown in the upper portion of FIG. 6. At this time, it is determined based on the rail 18 whether it is forward or reverse. If it is the reverse direction, the motor 30 is started and the turntable 34 rotates 180 degrees.

Next, as shown in the lower part of FIG. 6, the driving motor 24 is started and moved to the longitudinal center position of the target coil 100 to be bent, and then the driving motor 24 is stopped. In this case, the height of the tip of the strap chute arm 701 is preferably lower than the center height of the coil 100 when the inner side of the strap chute is turned inward.

When the adjustment is completed, the lifting and lowering hydraulic cylinder 56 is operated as shown in the upper part of FIG. 6, so that the entire bending machine body is advanced from the home position. Then, the strap chute 70 is moved to check and move the bidirectional center position of the coil 100. This determines the place where the coil 100 will be bent in the axial position.

When the movement is completed in this way, the strap chute arm swing hydraulic cylinder 80 is operated to pivot the strap chute arm 701 inward. The operation of the hydraulic chute cylinder for turning the strap chute arm 80 is a pressure drop when the auxiliary switching valve 90 shown in FIG. 4 is opened, the spring 84 in the housing 82 is in close contact with the strap chute arm 701. ) Is operated by rotating at a low speed, and the pressure is controlled through the pressure regulating valve (88).

Then, when the proximity sensor 77 installed at the tip of the strap chute arm 701 approaches the coil 100 and is detected, the auxiliary switch valve 90 is closed, and the main switch valve 92 is switched to the strap chute. The arm swing hydraulic cylinder 80 is in a pressureless state, so that only the pressure that the spring 84 is in close contact remains. Therefore, in this case, as shown by the dotted line in FIG. 7A, the coil 100 may be sandwiched between the ends of the strap chute arms 701.

After that, when the push-up cylinder 36 descends in the above state, the entire bending machine body portion descends a predetermined section, and at this time, the front end of the strap chute arm 701 has a rubber roller ( 741 rolls to continue turning further inward, resulting in the state of FIG. 7B. Then, the tip ends of both strap chute arms 701 meet, whereby the limit switch 78 is touched. The main selector valve 92 is then switched and the push up cylinder 36 is stopped. In this way, the position adjustment for supply of the band 116 is completed.

Next, the band 116 is supplied from the strap dispenser 58 as shown in FIG. 6 in a state where the preparation is completed as described above.

It is spread through. The strap dispenser 58 is the same as that of a conventional stationary banding machine, and is a device for discharging the band 116 to the outside at high speed by pneumatic operation, and the banding machine head 40 is also a conventional stationary banding machine. The same thing as this is that it has the hole which penetrates the band 116 supplied, and the means which receives and supports the band | band | band 116 which were collect | recovered again, and is a device which can combine and bind them together by tying them together.

When the replenishment of the band 116 is completed, the head hydraulic cylinder 66 is lowered and the bending machine head 40 is lowered together with the carriage 48. Then, as shown in FIG. 7B, the touch bar 44 touches the upper portion of the coil 100. Accordingly, the limit switch 42 is touched to stop the hydraulic cylinder 66 for the head. This completes the supply of the band 116 for bending.

At this time, the action of the strap chute 70 guides the band 116 as shown in FIG. 5 and the band 116 is spread in the strap chute 70, and then the band 116 in the bending machine head 40. When pulled tight, the band keeper 132 is fully buffered by the spring 138, and the band 116 is released while being unfolded on both sides, and the band keeper 132 is in the original position.

The banding is performed using the bending machine head 40 in the tightly tightened band 116, which is the same as the operation of the head of the conventional stationary bending machine.

After the banding, the head hydraulic cylinder 66 is raised, the main selector valve 92 is switched so that the strap chute arm 701 is rotated outward to its original position.

After that, if the number of bands is counted and less than a predetermined number, for example, three times, the lifting hydraulic cylinder 56 is operated to bend the next point in the axial direction of the coil 100, and when the position is confirmed, the main switching valve 92 ) Is switched to repeat the banding operation. If the number of bands is counted and corresponds to a predetermined number, for example, three times, the lifting hydraulic cylinder 56 is operated to move the body of the bending machine back to the home position, thereby ending the bending work for one coil 100. do.

For the bending operation of the next coil 100, the driving motor 24 is driven to move to the longitudinal center position of the next coil 100, and then the driving motor 24 is stopped, and then the bending is performed as described above. You will repeat the work.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto, and the technical idea of the present invention and the following by those skilled in the art to which the present invention pertains. Various modifications and variations are possible, of course, within the scope of equivalents of the claims to be described.

Applying the present invention as described above, since the strap chute is integrally formed, there is no need to provide a separate strap chute, it is easy to move to the position of the coil to be banded to securely and securely fasten the band hand work Due to this, it is possible to prevent safety accidents occurring in advance, and it has a very significant effect to shorten working time and improve work efficiency.
