Then, the thin strip 3 is cut by a knife 17 to cut off the thin strip on the side of the guide, the thin strip 3 is pushed by a holding roll 18 to the carrousel reel 13 to start continuous winding.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a winding equipment for guiding and winding a manufactured quenched metal ribbon onto a winding reel.

(Prior art) To produce a rapidly cooled metal ribbon, such as an amorphous ribbon, molten metal is rapidly solidified on the surface of a cooling roll rotating at high speed.
It is made into a continuous thin strip.

In particular, production of amorphous ribbons with a thickness of about 30 μm is carried out at a cooling roll circumferential speed of about 20 to 40 m/s.

A special device is required to convey, guide, and wind the ribbon produced at such high speeds.

JP-A-56-12257 and JP-A No. 59-138572
The cell publication discloses a ribbon conveying device that uses brush rolls, but the ribbon progresses unstable and meandering easily occurs due to tension differences, so it is difficult to convey the ribbon continuously. It's difficult. Furthermore, in order to apply an appropriate tension, it is necessary to apply a large rolling blade to the upper and lower brush rolls, and the ribbon is likely to break.

JP-A-59-43772 discloses a device using an ejector, but the suction force of the ejector is limited and is not suitable for transport to a remotely located take-up reel.

Also, Japanese Patent Publication No. 59-57864 and Japanese Patent Publication No. 60-48
No. 431 discloses a winding device equipped with a cell dancer roll, but it is necessary to increase the tension in order to improve the winding shape of the ribbon, and transmitting the tension directly to the cooling roll makes casting unstable. There is a risk of

Furthermore, in the proximity magnet reel disclosed in Japanese Patent Publication No. 59-34467, since the cooling roll and winding machine are in close contact with each other, it is difficult to install a measurement and control system, which is disadvantageous for stable production for industrialization. The internal blowing reel disclosed in JP-A-57-3901 also has a problem in that it is difficult to continuously take out the ribbon.

(Problems to be Solved by the Invention) The present invention advantageously solves the above-mentioned problems, and provides winding equipment that can capture the tip of the ribbon, draw it in, apply tension, and prevent meandering. It is a purpose.

(Means for Solving the Problems) The present invention provides a winding system that is combined with an apparatus for producing rapidly cooled metal ribbon, which comprises a cooling roll that rotates at high speed and a nozzle that guides the flow of molten metal onto the circumferential surface of the cooling roll. equipment,
Located behind the suction port facing tangentially to the cooling roll,
a pair of rotating rolls including a solid roll and a brush roll;
The guiding device is equipped with a guiding device consisting of a fan that suctions and crushes the tip of the quenched metal thin strip, which is placed downstream of the pair of rotating rolls, and a winding device that is placed apart from the manufacturing device. Winding equipment for a rapidly cooled metal ribbon that is movably provided on a line that passes through a winding device and reaches the rear of the winding device (first invention), a cooling roll that rotates at high speed, and a peripheral surface of the cooling roll. A winding equipment that is combined with a quenched metal ribbon manufacturing device consisting of a nozzle that guides the flow of molten metal, and a rotating solid roll and a brush roll arranged behind a suction port facing tangentially to the cooling roll. A guide device consisting of a pair of rolls and a fan that sucks and crushes the tip of the quenched metal ribbon, which is placed downstream of the pair of rotating rolls.
The guiding device is equipped with a winding device located apart from the manufacturing device and a tension breaking device for the quenched metal ribbon located between the manufacturing device and the winding device. This is a winding equipment (second invention) for rapidly solidified metal ribbon, which is movably provided on a line extending to the rear of a winding device.

Now, FIG. 1 shows a ribbon winding equipment according to the present invention.

In the figure, 1 is a cooling roll, 2 is a nozzle that supplies molten metal to the circumferential surface of the cooling roll 1, 3 is a ribbon, and 4 is an air knife that peels off the ribbon 3 from the cooling roll 1 by jetting air.
5 is a deflore roll, 6 is a duct hood with a suction port facing in the tangential direction of the cooling roll 1, 7 is a pair of rotating rolls arranged behind the duct hood 6, and 7a is a solid roll;
b is a brush roll, 8 is a fan disposed downstream of the pair of rotating rolls, 9 is a trolley for moving the guiding device 10 consisting of the pair of rotating rolls 6 and the fan 7, 11 is a winding device, 12 is a revolution axis, 13 .14 is a carousel reel, 15 is a swing arm, 16 is a defroll, 17 is a knife, 18 is a pressing roll, 19 is a dancer roll, 20.21 is a defroll, and 22 is a tension separating device.

Note that it is advantageous to use a Claran roll as the solid roll 7a of the rotating roll pair 7 to prevent meandering of the ribbon.

Further, it is more preferable that the brush roll 7b be wound in a double helical manner, in which the brushes are centrally distributed and tightly wound in a spiral shape from both ends of the brush roll toward the center, since this is advantageous in preventing meandering of the ribbon.

(Function) Next, the procedure when the winding equipment according to the present invention is applied to manufacturing a ribbon will be explained.

The molten metal poured from the nozzle 2 is rapidly solidified on the surface of the cooling roll 10 and becomes a ribbon 3. Next, the thin ribbon 3 adhering to the surface of the cooling roll 1 and rotating is peeled off from the cooling roll 1 by an air knife 4.

The peeled ribbon 3 is introduced from the duct hood 6 into the opening between the rotating solid roll 7ak and the brush roll 7b, and then the unsteady tip of the ribbon 3 is crushed by the fan 8. On the other hand, the remaining thin ribbon 3 in the steady portion is rolled down between the solid roll 7a and the brush roll 7b and tension is applied thereto. In this state, the pass line of the ribbon 3 is stable, and peeling from the cooling roll 2 progresses while contacting the deflation roll 5.

Next, the guiding device 10 is moved via the cart 9 toward the winding device 11 while maintaining tension on the ribbon 3. At this time, the relationship between the conveying speed v2 of the peripheral speed V1% of the rotating roll pair and the moving speed V of the cart is V, > V, >>
Let V.

FIG. 2 shows the state immediately before winding the ribbon 3 onto the carousel reel 13, 14 after passing it through the winding device 11. After the trolley 9 has advanced to the rear of the winding device 11, the tension control is performed. For this purpose, the ribbon 3 is brought into contact with the dancer roll 19, deflore rolls 20, 21, back tensioner 22, defloyl 23, and defloyl 16, and preparations for winding are started. Then, the revolution shaft 12 is rotated, and the first carousel reel 13 is brought close to the ribbon 3.

Next, as shown in FIG. 3 just before winding, the ribbon 3 is cut with a knife 17 to separate the ribbon on the guiding device side, and at the same time, the ribbon 3 is transferred to the carousel reel 13 with a presser roll 18. Press. The carousel reel 13 has the function of winding the ribbon and starts continuous winding.

It is noted that it is advantageous to control the speed of the carousel reel by detecting the position of the dancer roll 19 and adjusting it within the proper range, thus applying the appropriate tension to the ribbon.

In addition, the tension dividing device 22 serves to divide the tension of the line, maintain the high tension required for winding between the tension dividing device 22 and the carousel reel 13, and maintain the low tension between the tension dividing device 22 and the cooling roll 1. Responsible for

(Effects of the Invention) According to the present invention, a quenched metal ribbon such as an amorphous metal can be stably wound without causing troubles such as breakage or meandering, and industrialization of quenched metal ribbon production has been realized. obtain.
