JPH03161119A - Spacer paper inserting device for stainless steel strip - Google Patents

Abstract

PURPOSE:To prevent the break of spacer paper at the tail end of coil and to wind the spacer paper of a needed length by providing a deflector roll of which the position is changeable for adjusting the tension of space paper between the coiling reel for stainless steel strip and the delivery reel for spacer paper. CONSTITUTION:The delivery reel 5 for spacer paper is situated at a prescribed distance above a tension reel 4 and the deflector roll 6 is movable in the horizontal direction within the range of a prescribed distance from just below the delivery reel 5 for spacer paper. A position detector for the deflector roll 6 is ordinarily set so as to situate the deflector roll in the position of a prescribed distance from just below the delivery reel 5 for spacer paper. When the deflector roll 6 is out of this position, an electric motor on a truck 8 is revolved and the position control is done through a torque limiter.

Description

[Detailed description of the invention] Industrial application field> The present invention involves inserting a slipper into the stainless steel strip to prevent scratches caused by contact between stainless steel ropes when winding stainless steel 41F. This is related to equipment. Conventional technology When winding stainless steel m'IiF with a reel (usually called a tension reel), a winding method called trade-in is relatively often used. As shown in FIG. 3, this is a method in which the tension reel 4 is viewed from the right side in the coil advancing direction and wound clockwise, that is, from bottom to top. This method is often used because the coil 2 rotates in a direction that naturally winds up the interleaving paper 3 when inserting the interleaving paper 3 from above. <Invention tries to solve! Title i> In the case of this trade-in method, at the rear end of the coil,
The coil tail end 2a moves from bottom to top, and when it passes the top of the coil, it separates from the outer circumference of the coil and falls all at once from top to bottom while being swung around by centrifugal force. Since the interleaving paper 3 is made of thin kraft paper with a thickness of about 50 to 100 μm, the interleaving paper 3 is easily cut as shown in FIG. 4 due to the movement of the coil tail end 2a. There is a problem. This is because the inertial force of the slip-sheet dispensing reel 5 is large, and the slip-sheet 3 cannot withstand the impact caused by the protrusion of the tail end 2a of the coil, causing it to break. The interleaf paper is used to prevent contact scratches between the stainless steel strips mentioned above, as well as to prevent denting scratches that occur on the outer periphery of the coil.
For example, in order to prevent scratches on the outer stainless steel strip during band binding, or from contact with other coils during storage, there are cases in which one to several additional turns are wrapped around the outer circumference of the coil. be. However, there was a problem in that additional winding could not be done because the slipping paper would be torn due to the protrusion of the tail end of the coil. The present invention has been made in view of these problems, and an object of the present invention is to provide a slip-sheet inserting device that can prevent the slip-sheet from being cut by the tail end of the coil.

Means for Solving the Problems> The present invention provides an interleaving paper for preventing scratches caused by contact between stainless steel 4jF when winding a stainless steel W4 belt.
A device for inserting between stainless steel strips, characterized in that a variable position deflector roll for adjusting the tension of the stainless steel strip is arranged between the take-up reel of the stainless steel strip and the interleaf paper dispensing reel. This is a paper insertion device. Kusaku Kawa> The operation of the present invention will be explained with reference to Figures 1 and 2. The cutting of slip sheets due to the tail end of the coil popping out is caused by the inertia of the slip sheet dispensing reel being large compared to the strength of the slip sheets, so the payout speed of the slip sheet dispensing reel is relatively slow, and the slip sheets are not strong enough. This is because it will be cut without cutting. Therefore, a horizontally movable deflector roll 6 is provided between the slip sheet dispensing reel 5 and the tension reel 4.
By deflecting slip sheet 3, we stocked enough slip sheet length. This deflector roll 6 is
Normally, 1fl is controlled at a position where a predetermined length of slipping paper can be stocked between the slipping paper dispensing reel 5 and the tensioning reel 4, but if a sudden increase in tension occurs due to the tail end of the coil popping out, the tension will increase. Due to the horizontal component of the force, the interleaf sheet stock amount moves in the direction to decrease, thereby preventing the interleaf sheet 3 from being cut. After winding the coil, there are steps such as band binding and coil transportation, and the outer periphery of the coil is exposed to the risk of flaws, but to protect it, the required number of turns of interleaf paper 3 is wrapped, and then the outer circumference of the coil is It is sufficient to cut the interleaving paper 3 using a power cutter (not shown) on the output side of the paper dispensing reel 5. Embodiment> An embodiment of the present invention will be explained based on the drawings. Fig. 1 is a side view of the device of the present invention, and Fig. 2 is a side view of the device of the present invention.
This is a view from the arrow. In FIGS. 1 and 2, reference numeral 6 denotes a deflector roll for stocking slip sheets, which is moved on a rail 7 by a cart 8. The trolley 8 is horizontally moved by a torque motor 9, and is controlled so that the tension of the slip sheet 3 is constant. When abnormal tension is applied, the cart 8 moves in the direction of arrow A in order to keep the torque constant. Although the above description has been made using a torque motor, it is also possible to use a torque limiter and an AC motor to drive the AC motor in accordance with the torque limiter activation signal. Next, specific examples of the present invention will be described. SUS3 on the exit side of the continuous annealing and pickling line for stainless steel strips

It was wound at a speed of w. The interleaving paper has a thickness of 70n and a basis weight of 45g/
I used kraft paper with a width of 1010ms. The slip-sheet dispensing reel 5 is located 5 m above the tension reel 4, and the deflector roll 6 can move horizontally within a range of 4 m from directly below the slip-sheet dispensing reel 5. The position detector of the deflector roll 6 is set so that it is located 3.5 m from directly below. When the deflector roll 6 moves out of this position, the electric motor on the trolley 8 rotates and performs position control via a torque limiter. Winding of the coil was completed with a coil length of 1500 m. Due to the protrusion of the tail end of the coil, the deflector roll 6
was pulled toward the slip-sheet dispensing reel 5 by the slip-sheet 3 for about 2 m, but the slip-sheet 3 continued to be wound without being cut, and the slip-sheet 3 was wound 5 turns from the tail end of the coil, and the slip-sheet 3 Paper 3 was cut and the winding work for the coil was completed. <Effects of the Invention> As explained above, according to the present invention, the interleaving paper is not cut at the tail end of the coil, and it is possible to wind up the interleaving paper to the required length. This reduces dents and scratches that occur on the outer periphery of the coil when bundling or transporting the coil, improving surface quality.
