The present invention relates to a sheet inserting device installed on the coil skin pass line during the process of producing a stainless steel cold rolled sheet, more specifically, to prevent the sheet from being unwrapped and loosened when the winding operation of the coil wound at high speed. It relates to a deceleration stop device of a rolled roll.

In general, the winding machine is a device for winding a strip passed through a cold rolling or hot rolling mill into a coil for convenience of storage, transportation, and other processing before sending it to a post process. An interleaver insert is installed to insert interlayer strips between the strips to prevent scratches or breakage caused by mutual contact between the strips and the coils.

In general, a thin plate is a thin steel sheet having a thickness of about 0.3 mm or less, and is made by cold rolling a black coil or the like which has passed through a hot rolling mill in a cold rolling mill. The prepared thin plate is subjected to temper rolling to cold-anneal annealing or bright annealing to improve the mechanical properties of the thin plate and to correct the planar shape.

Here, since the processing speed during the temper rolling of the thin plate exceeds about 1000rpm, the slip sheets introduced between the thin sheets are also unwound at high speed from the interleaver coil and wound on the thin plate.

Therefore, when the main cylinder 25 is contracted and operated, the rotating member 22 is pulled out and laid in a horizontal direction. When the extended cylinder is operated, the rotating member 22 is set up in a vertical state, so that the curved member 23 is lowered in the interliner coil 150. It will be in close contact with the surface.

Unexplained reference numerals 26 and 27 are a sensing sensor and a sensing piece which are respectively installed on the upper portion of the base frame 20 and the lower portion of the rotating member 22 to detect the vertical state of the rotating member 22.

On the other hand, looking at the adjustment means, the guide member 31, which is convex guide 30 is formed in the longitudinal direction on the front surface of the rotating member 22, the concave guide is formed on the convex guide 30 is raised and lowered, Installed below the rotating member 22 and connected to the lower end of the guide member 31 to connect the vertical cylinder 32, the guide member 31 and the curved member 23 to raise and lower the guide member 31. A guide rod 34 and a curved member 23 installed at a lower end of the bar 33 and the curved member 23 and inserted into a guide groove formed at an upper portion of the rotating member 22 to guide the curved member 23. It is installed on the) includes a detection means for checking the interval with the kanji coil 150.

Accordingly, when the vertical cylinder 32 is stretched and operated, the curved member 23 is moved up and down in accordance with the changing width of the zigzag coil 150.

Here, the sensing means, the roll support member 41 is seated in the insertion groove 40 and the insertion groove 40 is installed in the upper center of the curved member 23, the idle roll 42 is coupled to the upper, roll support The support bar 43 is vertically installed below the member 41 and protrudes downward through a hole formed in the bottom surface of the insertion groove 40, and is inserted into the support bar 43 to between the insertion groove 40 and the roll support member 41. A sensing piece 45 is installed at the tip of the elastic spring 44 is installed in the elastic spring 44, the support bar 43 protruding below the curved member 23, the sensing bar 45 is installed on the side of the connecting bar 33 When the predetermined distance comes down is made including a detection sensor 46 for detecting it.

The sensing means can achieve the purpose by installing only in the center of the curved member 23, the idle roll 42 installed on the roll support member 41 than the other idle roll 24 installed on the curved member 23 Soaring a predetermined height so that the lower surface of the ganji coil 150 first touches the idle roll 42 of the sensing means.

Hereinafter will be described the operation of the present invention.

First, looking at the mounting process of the ganji coil 150, when rotating the drive cylinder 15 installed in the rail member 10 to push the moving member 11 to the outside to open the gap between the moving member (11) do.

When the gap between the clamp cone 13 of the moving member 11 is wide enough to insert the interleaver coil 150, the main cylinder 25 is extended to operate the rotating member 22, which is divided in a horizontal state, vertically. Will be put in a state.

When the rotating member 22 is in a vertical state, the sensing piece 27 installed at the bottom of the rotating member 22 is sensed by the sensing sensor 26 installed in the base frame 20, and the main cylinder according to the signal of the sensing sensor. 25 stops the stretching operation.

Then, when the crane is moved to place the Kanji coil 150 on the curved member 23 on which it stands, both ends of the Kanji coil 150 are supported by both curved members 23 which are curved in a semicircle shape, and in this state. By rotating the driving cylinder (15) in the reverse direction to move the moving member 11 to the center, so that the clamp cone installed on the moving member 11 is simply fitted to the sleeve of the ganji coil 150.

In addition, when the curved member 23 is placed vertically and the detection signal of the sensing piece is output to the detection sensor 26, the vertical cylinder 32 is extended and operated at the same time to move the curved member 23 toward the lower portion of the interleaver coil 150. Is raised.

That is, when the vertical cylinder 32 is extended and operated, the guide member 31 installed at the tip of the piston rod of the vertical cylinder 32 moves up and down through the convex guide 30 of the rotation member 22, and thus the guide. The curved member 23, which is fixedly connected to the member 31 via the connecting bar 33, is raised and lowered with respect to the rotating member 22.

At this time, the guide rod 34 installed in the curved member 23 slides along the guide groove formed in the rotating member 22 to guide the curved member 23.

On the other hand, when the curved member 23 continues to elevate toward the lower surface of the Kanji coil 150, the idle roll 42 protruding in the center of the inner surface of the curved member 23 is the first lower surface of the Kanji coil 150 As the curved member 23 continues to elevate, the idle roll 42 is pressed by the interleaver coil 150.

The idle roll 42 that is pressed down presses the elastic spring 44 installed in the insertion groove 40 of the curved member 23 and descends into the insertion groove 40 and the support bar 43 installed below the roll guide member 31. ) Is moved downward relative to the curved member (23).

Therefore, the sensing piece 45 installed at the end of the support bar 43 is detected by the sensing sensor 46 in close proximity to the sensing sensor 46 installed in the connecting bar 33, and the vertical cylinder 32 according to the signal of the sensing sensor. Stops the operation so that each idle roll (24, 42) installed in the curved member 23 under the current pressure to be in close contact with the ganji coil 150.

As such, the idle rolls 24 and 42 provided on the inner surface of the curved member 23 adhere to each other at a constant pressure along the surface of the Kanji coil 150 to support the Kanji coil 150 and at the same time prevent rotation of the idler. The cold goes off while the sheet is stopped, but prevents it from being released.

On the other hand, when the slipper continues to be released and the diameter of the slippery coil 150 is reduced, the idle roll 42 pressed by the slippery coil 150 is applied to the elastic return force of the elastic spring 44 installed in the insertion groove 40. By being pushed up continuously, the support bar 43 installed on the roll support member 41 is also raised so that the sensing piece 45 installed on the support bar 43 is far from the detection sensor 46.

When the detection sensor 46 and the detection piece 45 are separated by a predetermined interval so that the detection piece is not detected by the detection sensor, the vertical cylinder 32 is extended and actuated to raise and lower the curved member 23 according to the corresponding signal.

As mentioned above, as the curved member 23 moves up and down, the idler roll 42 is pushed by the zigzag coil 150 and the sensing piece 45 is detected by the sensing sensor 46 again and is vertical in accordance with this signal. The cylinder 32 stops working.

As the lifting operation of the vertical cylinder 32 is repeatedly performed according to the diameter of the zigzag coil 150 as described above, the curved member 23 is kept in close contact with the zigzag coil 150 until the zigzag coil 150 is released. Coil 150 is to continue to prevent idle rotation and support the icebreaker.

According to the deceleration stop device of the rolled paper roll according to the present invention as described above, it is possible to reduce the effort to align the center axis in the state in which lifted up the rolled paper coil with a crane when mounting the rolled coil, it is possible to easily install the rolled coil.

In addition, even if a rapid stop during the high-speed winding of the thin plate is prevented the idle rotation of the kanji coil can prevent the kanji flowing down, thereby preventing the damage of the product from the contamination source of the floor.
