Description

[0001] APPARATUS AND METHOD FOR WINDING STEEL STRIP [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a strip winding device and a winding method for facilitating handling of a coil wound by allowing a tail end of a strip to be accurately positioned at a set position when winding is completed.

Steel products that are manufactured in the form of thin plates through the rolling process are called strips. These strips are wound in the form of coils while finishing the rolling process for convenience of transportation, storage and the like. Then, the wound coils are transported to a packaging position and then wrapped by a bending machine or the like.

The winding device for winding the strip includes a winding section such as a tension reel for rotating the sleeve to wind the strip, a guide means for guiding the conveyance of the strip toward the winding section, And cuts the strip supplied in the strip transport path before the take-up part. In addition, the winding device may include a coil transfer unit for transferring the wound coil from the winding section to the bending machine. The coil transfer unit can move from the winding section toward the bending machine while the wound coil is mounted thereon.

On the other hand, the wound coil is placed on its outer surface with a tail end (cut portion), and the end position of the strip is located at about 140 degrees in a rotating direction for winding from the upper end of the coil good. This is because if the end located on the outer surface of the wound coil is too long or short, it may interfere with the operation of transferring the coil to the coil transfer unit after winding or bending operation in the bending machine. For example, if the end of the coil is left too long in the state that the coil is mounted on the coil transfer unit, the end of the coil may be caught by another device during the transferring process, and the coil may be rolled over.

However, since the coils wound in a normal winding device may have different winding conditions or the like, it is difficult to accurately maintain the position of the strip end in the state where the winding is completed. Of course, after the strip is cut, the position of the end can be adjusted to some extent by calculating the rotation angle of the winding section and the distance between the winding section and the cut section. However, the length of the remaining strip from the cutting position to the coil is long, It is difficult to realize winding in the same condition every time because thickness, width, etc. may be different.

In the following description, the strip in the coil- For convenience, it can be expressed as a coil (5).

The cut portion 40 may be formed of a shearing machine or the like which is provided in the conveying path 20 and cuts the strip 1 being fed. The cut portion 40 cuts the strip 1 being supplied when the strip 1 is wound by a predetermined amount on the take-up portion 30 so that the strip 1 wound in the form of a coil in the take- Length or titration volume).

 The coil transfer unit 50 can be positioned at the lower portion of the winding unit 30 and can move to the subsequent steps in a state in which the coil 5 with the wound coil 5 mounted thereon is moved. For example, it can be transferred to a packaging step in which a bending machine (not shown) is located in a state where the coil 5 wound on the winding part 30 is mounted on the upper part thereof. This coil transfer unit 50 can be raised or lowered for the mounting of the coil 5 and can move in the lateral direction along the rail for transferring the coil 5.

2, 4, and 5, the coil transfer unit 50 includes a body portion 51 capable of moving up and down and a body portion 51 for supporting the wound coil 5 And two idler rollers 52 which are provided in the space 53 between the two skid blocks 52 and which are in contact with the lower end of the coil 5 wound when the body 51 is lifted up, A shaft support member 55 which rotatably supports both ends of the idler roller 54 and which is rotatably supported on the body portion 51 so as to be able to move up and down; As shown in FIG.

Referring to FIG. 1, the strip winding apparatus cuts the strip 1 being fed by the cut section 40 when the strip 1 is wound on the winding section 30 by a predetermined amount. The winding section 30 finishes the winding operation after winding the remaining strip 1 existing in the conveying path 20 from the cut section 40 to the winding section 30. [ After completion of the winding work, the coil transfer unit 50 transfers the wound coil 5 to a subsequent process.

On the other hand, the position of the tail end of the strip 1 in the wound coil 5 is approximately 135 to 145 degrees from the upper end of the coil 5 in the rotating direction for winding, that is, It is preferable that the lower end of the coil 5 is close to the lower end. If the distance between the point where the coil 5 wound on the coil 5 is mounted in the coil transfer unit 50 and the end of the coil 5 is too long or too short, the work is transferred to the bending machine using the coil transfer unit 50 This is because it may cause troubles in the process of packaging the coil 5 and the like.

In consideration of this point, the strip winding apparatus according to the present embodiment is arranged so that the end of the strip 1 at the end of the winding is positioned at the predetermined position, And a terminal detector 70 for detecting the terminal. The control unit controls the end of the operation of the winding unit 30 based on the information detected by the end detection unit 70 so that the winding can be finished in a state where the end of the strip 1 is exactly stopped.

2, 4, and 5, the end detection unit 70 is installed at one side of the coil transfer unit 50 so as to be rotatable. The end detection unit 70 includes a coil (not shown) wound around the take- A driving unit 72 for moving the operating member 71 to open or close the operating member 71 and an operating member 71 capable of approaching the operating member 71 to detect the end of the strip 1, And may include a first sensor 73 and a second sensor 74.

4 and 5, the actuating member 71 is provided in the form of a panel, and a shaft 71a provided at one end of the actuating member 71 is rotatably supported on the side of the body portion 51 of the coil transferring unit 50. [ The drive unit 72 that operates the operation member 71 includes a driven gear 72a coupled to the shaft 71a of the operation member 71 and a driven gear 72b engaged with the driven gear 72a And a driving motor 72c that is installed on the body portion 51 of the coil transfer unit 50 and rotates the driving gear 72b in the forward direction and the reverse direction.

When the drive gear 72b rotates by the operation of the drive motor 72c, the drive unit 72 rotates the driven gear 72a and the operation member 72 connected to the driven gear 72a by the shaft 71a Can be rotated up and down. Therefore, the actuating member 71 can be rotated upwards to be close to the wound coil 5, or rotated downward to be folded. The side surface of the body portion 51 of the coil transfer unit 50 is provided with a receiving space 59 larger than the size of the operating member 71 on its side surface so as to receive the operating member 71 when the operating member 71 is rotated downwardly. can do.

2, the operation member 71 includes at least one idler roller 75 for reducing friction with the strip 1 wound up in an upwardly rotated state, and a plurality of balls 76 can do. 3 and 4, the idler roller 75 is installed in such a manner that a part of the idler roller 75 is exposed on the upper surface of the operation member 71 so as to be in contact with the strip 1 to be wound. The plurality of balls 76 are disposed so as to be spaced apart from each other, and the upper portions of the balls 76 are exposed to the upper portion of the operation member 71 so as to be in contact with the strip 1 to be wound. Each ball 76 can be rotatably supported by a ball supporting member 76a coupled to the upper surface of the actuating member 71. [

The first sensor 73 and the second sensor 74 may be installed on the upper surface of the operation member 71 such that the first sensor 73 and the second sensor 74 are spaced apart from each other in the direction in which the take- have. The first sensor 73 can be disposed at 135 degrees from the upper end of the coil 5 wound with the operating member 71 in the unfolded state in the direction in which the winder rotates, 71 can be arranged at a point 145 degrees in the direction in which the winding section 30 is rotated from the upper end of the coil 5 wound in the unfolded state

The arrangement of the sensors 73 and 74 is such that when the end of the strip 1 is detected by the first sensor 73 when the winding unit 30 rotates in the winding end process, The end of the strip 1 is stopped at the position (the set position) between the first sensor 73 and the second sensor 74 so that the winding operation can be terminated.

The controller can determine whether the end of the strip 1 has passed the position of the second sensor 74 through the second sensor 74 and whether the end of the strip 1 has passed the position of the second sensor 74 The winding operation can be terminated because the end of the strip 1 is located between the first sensor 73 and the second sensor 74. [ If it is determined that the end of the strip 1 has passed the position of the second sensor 74, the end of the strip 1 is out of the set position, the control unit rotates the winding unit 30 one more time The winding operation can be completed in a state where the end of the strip 1 is positioned at the set position (between the first sensor and the second sensor).

The present embodiment shows a case where the end detection unit 70 for detecting the end of the strip 1 is installed on the side of the body 1 of the coil transfer unit 50 in the winding completion step, Is not limited to this. Although not shown in the drawing, the termination detecting unit 70 can also be supported by a separate supporting device disposed on the outer side of the wound coil 5.

In addition, the strip winding device of the present embodiment can more stabilize the operation of the winding completion step by controlling the feeding and winding speed of the strip 1 more slowly after the strip 1 is cut by the cut portion 40. To this end, as shown in FIG. 1, it is determined whether or not the end of the strip 1 has passed (the end of the strip cut at the cut-out portion is directed toward the take-up portion) to the feed path 20 between the cutting portion 40 and the take- The control unit may control the conveying and winding speed of the strip 1 based on the sensing information of the passage sensing unit 80. In this case,

That is, if it is determined that the end of the strip 1 has passed through the passage sensing unit 80, the control unit controls the take-up unit 30 to rotate at the first feeding speed, It is possible to control the winding unit to rotate according to the second feeding speed that is slower than the first feeding speed. Here, the first conveying speed may be 60 to 30 mpm, which is the same as when the winding unit 30 normally winds the strip 1, and the second conveying speed may be 15 mpm, which is a relatively slow conveying speed. That is, after the end of the strip 1 passes through the passage sensing portion 80 of the conveyance path 20, the conveying and winding speed can be made relatively slow. The numerical values set forth herein are merely examples, but are not limited thereto.

The detection of the end of the strip 1 by the first and second sensors 73 and 74 of the end detecting portion 70 can be performed more accurately by making the strips to be conveyed and wound at such a slow speed at the completion stage of the winding operation And the winding operation can be ended in a state where the end of the strip 1 is accurately positioned at the set position. In Fig. 1, reference numerals 91 and 92 denote supporting rollers which move to the outer surface of the coil 5 wound in the winding completion step and support the outer surface of the wound coil 5.

Next, a description will be given of a method of winding the strip by using the strip winding apparatus.

As shown in Fig. 1, the strip 1 fed from the strip feeding section 10 through the feeding path 20 can be wound in the form of a coil in the winding section 30. Fig. 6A, the coil transfer unit 50 may be positioned at a lower portion of the take-up unit 30 and may be spaced apart from the end of the coil 1, which is provided in the coil transfer unit 50, The sensing portion 70 can be held in a folded state so as to be accommodated in the accommodating space 59 on the side of the coil transferring unit 50. [

When the strip 1 wound on the winding section 30 reaches the winding amount set up (the length of the wound strip or the wound volume, etc.), the control section operates the cut section 40 located on the transfer path 20 to supply The strip 1 being cut is cut. 6 (b), the control unit moves the coil transfer unit 50 up to the lower portion of the wound coil 5 at the same time that the strip 1 is cut, And controls the installed end detecting unit 70 to be extended toward the outer surface of the coil 5. That is, the end detection unit 70 moves to the setting position of the outer surface of the coil 5 wound to sense the end of the strip 1. [ At this time, the elevation height of the coil transfer unit 50 may be a predetermined height, and the idler roller 54 may be in contact with the lower surface of the wound coil 54 or close to the coil 5. At this time, the support rollers 91 and 92 located on the outer side of the wound coil 5 move toward the outer surface of the wound coil 5, so that the outer surface of the coil 5 can be stably supported.

The control unit detects whether the end of the strip 1 has passed through the passage sensing unit 80 positioned between the cutout 40 and the winding unit 30 after the strip 1 is cut by the cutout 40 do. If it is determined that the end of the strip 1 has passed the passage sensing unit, the control unit rotates the winding unit 30 to match the first conveying speed, and the end of the strip 1 passes through the passage sensing unit 80 The winding unit 30 is rotated so as to match the second feeding speed that is slower than the first feeding speed. That is, the completion of the winding operation, the rotation of the winding section 30 is relatively slow.

6C, the control unit senses the end of the strip 1 wound via the end detection unit 70 disposed outside the wound coil 5, and the end detection unit 70 detects the end of the strip 1 wound on the strip 1, the operation of the winding unit 30 is stopped so that the winding operation can be terminated with the end of the strip stopped at the set position. When the first sensor 73 of the end detection unit 70 senses the end of the strip 1, the winding unit 30 stops immediately so that the end of the strip 1 is connected to the first sensor 73 So that the winding operation is completed in a state in which it is positioned between the second sensors 74.

On the other hand, when the end sensing unit 70 detects the end of the strip 1 and ends the winding, it is detected that the end of the strip 1 has passed through both the first sensor 73 and the second sensor 74 The control unit can determine that the end of the strip 1 is out of the winding end position set by the end. At this time, the controller can further rotate the winding unit 30 so that the first sensor 73 and the second sensor 74 can detect the end of the strip 1, and the end of the strip 1 is set It is possible to control the winding operation to end in a stopped state. At this time, by controlling the winding unit 30 to rotate more slowly, the first sensor 73 can easily detect the end of the strip, and the stopping operation of the winding unit 30 can be performed more accurately.

After the end of the strip 1 is stopped at the set position (between the first sensor and the second sensor of the end detection unit), as shown in FIG. 6D, the coil transfer unit 50 is further raised So that the lower portion of the wound coil 5 is mounted on the coil transfer unit 50. At this time, the shaft support member 55 is lowered while the idle roller 54 is pushed by the coil 5, and the load sensing unit 58 senses the state of the shaft 5, Can be detected. If it is detected in this way that the loading is completed, the coil transferring unit 50 stops further rising and the end detecting portion 70 can also be folded toward the side of the coil transferring unit 50. The supporting rollers 91 and 92 which support the coil side are separated from the coil 5 and the winding portion 30 is also switched to a state in which the coil 5 can be separated.

In this state, the coil transfer unit 50 moves in the lateral direction to move the coil 5 to a subsequent process (bending process, etc.). At this time, since the end of the strip 1 exposed to the outside of the coil 5 held in the coil transfer unit 50 maintains an appropriate length (set length), smooth transfer can be realized without overturning or jogging, It is possible to achieve smooth operation.
