Description

TECHNICAL FIELD The present invention relates to an apparatus for producing a quenched metal ribbon such as an amorphous alloy ribbon produced by a single roll method and wound by a winder, In particular, the present invention relates to an apparatus for producing a quenched metal ribbon capable of continuously winding a ribbon.

[Conventional technology]

In recent years, development of a manufacturing technique for directly processing a molten metal (including an alloy; the same applies hereinafter) directly into a metal ribbon by a liquid quenching method such as a single roll method or a twin roll method has been advanced. The first important requirement in such a direct plate making technology is the plate making technology related to the uniformity of the plate thickness and the surface texture, but when considering industrial production, coil production is similar to that. It is also important to establish a winding technique for winding into a coil.

In the case of a crystalline metal ribbon having a plate thickness of 100 μm or more, the plate-making speed is usually 5 m / sec or less due to the restriction of solidification due to heat transfer to the cooling body. In this case, it is possible to wind by transporting with a mesh belt having a clamper and winding with a heat-resistant belt wrapper as proposed in JP-A-61-88904.

However, in the case of a quenched metal ribbon, the plate thickness is extremely thin, 50 μm or less, and the plate-making speed is usually 20 m / sec or more, so that the technique used for the crystalline metal ribbon cannot be applied as it is. Moreover, since the material properties of the manufactured ribbon change according to the plate-making speed, and the mechanical strength is often impaired, the plate-making speed can be changed even when winding or rewinding on the take-up reel. This, in turn, has made the winding technology more difficult to develop.

In JP-A-57-94453 and JP-B-59-34467, the problem of conveyance is avoided by arranging the take-up reel close to the cooling roll, and a magnet is embedded in the take-up reel. , A thin strip is wrapped around.

This method can be said to be a clever method in which the troublesome conveyance technique is made unnecessary by disposing the winding machine in the vicinity of the cooling roll.

However, this method is not always suitable for continuous production because the winder is too close to the chill roll. Moreover, it is not a preferable method in view of industrial production, because it is not possible to install a space for installing an inspection device for the plate thickness, holes, etc., or a tension control device.

In this respect, JP-A-56-12257, 59-43772 and 59-1385
In each publication of No. 72, etc., on the premise that the winder is arranged at a remote position of the cooling roll, the development of the conveyance technology is addressed from the front. All of these are intended to effectively convey by using a brush roll or a brush / solid roll together with a fan as a pinch roll for capturing a thin strip.

The ribbon produced by rapid solidification on a chill roll is
After being peeled off from the cooling roll, it reaches the pinch roll via the hood. Then, the pinch rolls roll down to give the ribbon proper tension, and the unloading carriage moves toward the winder.
As a result, the ribbon is conveyed to the reel.

The winding machine continuously winds the ribbon wound on the sleeve fitted on the reel, and when the sleeve is full, unloads the wound sleeve and replaces the sleeve for the next winding. Is required.

In a conventional cold rolling or hot rolling line, the rolling plate carrier does not run, so the coil unloading device can run on the floor. However, the chill roll and winder are placed remotely,
This method cannot be adopted in a quenched metal ribbon manufacturing apparatus in which a carrier truck travels during that time, and continuous ribbon winding cannot be performed.

[Problems to be Solved by the Invention]

SUMMARY OF THE INVENTION In order to solve the above-mentioned drawbacks of the prior art, the present invention aims to provide a device for manufacturing a quenched metal ribbon, in which the sleeve can be easily replaced and the ribbon can be continuously wound.

[Means for Solving the Problems]

The present invention, in order to solve the above problems, is rapidly solidified on a cooling roll that rotates at a high speed to form a ribbon, and then a quenched metal ribbon that is peeled off from the roll surface with an air knife, a hood that guides to a pinch roll. In a device for manufacturing a quenched metal ribbon, which comprises a pinch roll for capturing the guided ribbon, a carriage for loading the pinch roll, and a winder for winding the transported ribbon, An apparatus for producing a quenched metal ribbon, characterized in that an unloading device for unloading the taken ribbon from a reel of a winding machine and unloading the ribbon is provided outside a traveling space of a carrier truck. The device can be an unloading carriage that travels on a gate-shaped girder that is arranged across the traveling space of the transporting carriage, and a unloading arm that is connected to the lower part of the unloading carriage and that can be opened and closed and opened and closed. The body is fitted to the reel of the winder Can be assumed that a thin band and embracing clamp by opening and closing a sleeve for winding, comprising a clamping possible positioning means opposite ends of the sleeve at its distal end.

[Action]

 Hereinafter, the present invention will be specifically described with reference to the drawings.

1 and 2 are explanatory views showing a method for winding the ribbon.

Molten metal is ejected from the pouring nozzle 2, forms a molten metal puddle with the cooling roll 1, and is rapidly cooled and solidified by heat removal from the cooling roll to form the ribbon 3. The thin strip adhered on the cooling roll is peeled off by the air ejected from the air knife 4, and is blown in the hood 6 by suction by the fan 8. The thin strip including the solid reel 7a and the brush roll 7b that has reached the pinch roll 7 is captured by the pinch roll and tension is applied to form a pass line with the deflor 5. The thin strip that has passed through the pinch roll is crushed by a fan to become a crushed thin strip 3a. Since the pinch roll and the fan are mounted on the transport carriage 9 and the carry-out device is arranged outside the traveling space of the transport carriage, the thin strip is moved to the winder by moving the transport carriage to the winder 13. Can be transported.

During this transportation, the distance between the deroll 5 and the pinch roll becomes long, so the support roll 10 and the del roll 1
A deflor 11, which is a dancer device for tension adjustment composed of 5,17 and a dancer roll 16, is used.

The ribbon wound around the reel 13b by a winding machine (not shown) becomes a coil that is continuously wound, and when the reel 13b winds a predetermined amount of ribbon, the reel revolution wheel 12 rotates to rotate the reel. The position is exchanged with 13a.

Next, with reference to FIG. 3 and FIG. 4, the operation of the device for taking out the wound ribbon from the reel of the winding machine and carrying it to a predetermined position will be described.

In FIG. 3, a sleeve 23 is fitted on the reel 13b, and a ribbon (not shown) is being wound on the surface of the sleeve.
A sleeve 22 is fitted to a, and a coil 21 is already formed on the surface of the sleeve 22 by a predetermined amount.

The unloading cart 19 travels on the gate-shaped girder 20 and approaches the reel 13a, and the arm body whose vertical direction is controlled by the lifting cylinder 27.
18 opens and closes to hold the ends of the sleeve. As shown in FIG. 4, the distal ends of the arms are tapered positioning means 28 and 29 capable of holding both ends of the sleeve, and the arms are automatically positioned when the arms are closed.

The unloading cart with the coiled sleeve removed from the reel goes backwards on the gate type garter, stops on the coil skid 26 and lowers the lifting cylinder, opens the arm and puts the coil 21 and the sleeve 22 on the coil skid 26. . The coil skid sequentially carries the coils out of the system by a conveyor.

Next, the unloading carriage moves onto the adjacent sleeve skid 25 and takes the empty sleeve 30 and inserts it into the reel 13a. Then, the revolution wheel 12 revolves, and the sleeve 30 performs the next winding.

In this way, it is possible to carry out the winding continuously despite the use of a traveling carriage.

〔Example〕

Using the apparatus shown in FIGS. 1 to 4, plate making, carrying and carrying out were carried out under the following conditions.

Molten metal: Fe ₈₀ B ₁₀ Si ₉ C ₁ (atomic%) Melting temperature: 1300 ℃ Pouring nozzle: 100mm width slit Cooling roll: Water cooling, made of copper alloy Cooling roll peripheral speed: 25m / sec Solid roll: Diameter 200mm, steel Made brush roll: Diameter 200mm, stainless wire diameter 0.15mm Pinch roll peripheral speed: 28m / sec Winding tension: 1kgf / mm ² As a result, a ribbon with a thickness of 20μm and a width of 100mm is manufactured. After being applied, it was conveyed.

Meanwhile, the unloading device is on standby above the traveling space of the carrier vehicle, and the ribbon conveyed by the carrier vehicle does not come into contact with the unloading device.
It was wound on the sleeve fitted in b), and then the sleeve was sequentially replaced and continuous winding was performed, and continuous production was possible without any problems in cycle time and position accuracy during this period.
