Description

[Detailed explanation of the idea]

<Industrial Application Field> The present invention relates to a winding device that continuously winds a thin metal plate manufactured by a molten metal quenching method simultaneously with the manufacturing. <Conventional technology> In recent years, a method has been devised to produce thin plates by spraying molten metal onto the outer peripheral surface of a cooling roll that rotates at high speed and rapidly cooling the metal. It is attracting attention because it is relatively easy to obtain metals. In this way, the metal thin plate manufactured through the molten metal quenching process is wound up by a winding wheel that rotates at a peripheral speed equal to the peripheral speed of the cooling roll, but the peripheral speed of this winding wheel is extremely high. Therefore, special measures are required for the operation of winding the tip of the thin metal plate around the winding wheel at the start of winding. Most conventional take-up wheels have a structure in which the thin metal plate is magnetized by an electromagnet or has a permanent magnet embedded, as the thin metal plate is made of a ferromagnetic material. The tip of the winding wheel was magnetically attracted to the outer peripheral surface of the winding wheel. <Problems to be solved by the invention> The method of winding the tip of a thin metal plate around a winding wheel using magnetic force is completely impossible to apply to non-magnetic metals. Also, even though it is a ferromagnetic metal, the plate thickness is thin, so
The polarization of the magnetic poles in the direction of the plate thickness is not sufficient, and the adsorption force between the thin metal plate and the winding wheel is weak, making it difficult for the winding wheel to catch the tip of the thin metal plate that is fed in at high speed. In particular, when cutting a thin metal plate that is passing close to the winding wheel and downstream from it, the adsorption force of the winding wheel to the thin metal plate is further increased. Because of the need to be strong, there was a problem in that the magnetic force generator built into the winding wheel had to be large-scale and effective. <Means for Solving the Problems> A thin plate winding device according to the present invention includes a cooling roll that rapidly cools the molten metal supplied to the outer peripheral surface and drives and rotates to continuously feed out the thin metal plate;
A guide roll on which the tip end side of the thin plate sent out from the cooling roll is arranged, and a winding wheel provided between the guide roll and the cooling roll and on which the thin plate is wound with an adhesive layer formed on its outer peripheral surface. a crimping roll which pinches the thin plate and faces the winding wheel and is movable back and forth in the opposite direction to press the thin plate to the outer peripheral surface of the winding wheel; the guide roll and the winding wheel; The thin plate is provided between the winding wheel and the winding wheel, and is provided with a cutting machine that cuts the thin plate which is placed between the guide rolls and the winding wheel when winding is started. <Function> When molten metal is supplied to the outer circumferential surface of the rotating cooling roll, the molten metal is rapidly cooled and turned into a thin plate, which is continuously sent to the guide roll side. While the thin plate is passing between the take-up wheel and the pressure roll, when the pressure roll moves forward toward the take-up wheel, the thin plate is pressed against the adhesive layer of the take-up wheel and becomes integrated with the take-up wheel. As the take-up wheel rotates, the crimped portion of the thin plate is rolled up, but in the middle of this, the cutting machine cuts the part of the thin plate located between the guide roll and the take-up wheel. The thin plate on the upstream side is wound up by the take-up wheel. <Example> As shown in FIGS. 1 and 2, which represent the working concept of an embodiment of the thin plate winding device according to the present invention, the area immediately below the crucible 2 storing the molten metal 1 is driven by a high-speed drive rotation. A cooling roll 3 is provided, and a molten metal 1 is poured onto the outer peripheral surface of the cooling roll 3 from a nozzle 5 of a crucible 2 having an opening size corresponding to the width of the thin plate 4.
is being supplied continuously. On the downstream side of the thin metal plate 4 sent out from the cooling roll 3,
A guide roll 6 that guides the leading end of the thin plate 4 to another winding wheel or winding device (not shown) is rotatably arranged, and the thin plate 4 passes over this guide roll 6. There is. A winding wheel 8 having an adhesive layer 7 formed on its outer peripheral surface is rotatably arranged between the cooling roll 3 and the guide roll 6, and feeds the thin plate 4 to the downstream side of the guide roll 6 (left side in the figure). In this case, the gap between the winding wheel 8 and the thin plate 4 is set to be large. The adhesive layer 7 is
It is coated with an adhesive to which the thin plate 4 easily adheres, and the opposite side of the winding wheel 8 holding the thin plate 4 is reciprocated in the direction opposite to the winding wheel 8 by the operation of an actuator 9. A rotatable pressure roll 10 is rotatably provided. This pressure roll 10 presses the thin plate 4 against the adhesive layer 7 of the winding wheel 8 and presses the thin plate 4 onto the winding wheel 8.
These guide rolls 6, take-up wheels 8, and pressure rolls 1
The circumferential velocity (angular velocity) of 0 is set equal to the circumferential velocity of the cooling roll 3 in order to prevent tension from being applied to the thin plate 4 due to synchronous rotation. A cutting machine 11 is provided between the guide roll 6 and the winding wheel 8 to cut the thin plate 4 that is stretched between them, and the thin plate 4 is in a crimped state. Winding wheel 8
As the thin plate 4 rotates at a high speed, the thin plate 4 is cut by the impact generated when it collides with the tip of the cutting machine 11. Note that, as this cutting machine 11, it is of course possible to use a conventionally well-known discharge cutting device or the like. Next, using this device, A: Fe-Ni-Si-B

[Table] Alloy, B: Fe-Ni-P-B alloy, C: SUS304
The results of manufacturing thin plate 4 are shown in the attached table. Specifically, these molten metals 1 are passed from a nozzle 5 to a cooling roll 3.
As the cooling roll 3 rotates at high speed, the molten metal 1 is rapidly cooled and stretched.
The material B became an amorphous thin plate 4, while the material C became an amorphous thin plate 4. For C, which is a non-magnetic material, the actuator 9 is driven 1 to 2 seconds after the start of spraying the molten metal 1 onto the cooling roll 3, and the pressure roll 10 is moved to the winding wheel 8 as shown in FIG. By pressing the thin plate 4 against the winding wheel 8, the winding start portion of the thin plate 4 was pressed against the winding wheel 8, and the unnecessary portion downstream from this was cut off, resulting in good winding. <Effects of the invention> According to the thin sheet winding device of the present invention, the outer peripheral surface of the winding wheel is formed with an adhesive layer, and the thin sheet is crimped onto the winding wheel by a pressure roll, so that the thin sheet of non-magnetic metal can be In addition to being capable of winding, the winding device can be made at a low cost because it does not utilize magnetic force. Furthermore, since the bonding force between the thin plate and the winding wheel is strong, it is possible to start winding even the thin plate passing at high speed without any problem.
