Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scrap coil treating apparatus for winding an unrolled portion produced at the front and rear ends of a strip during rolling into a scrap coil.

[0002]

2. Description of the Related Art In hot rolling or cold rolling, unrolled parts or off-gauge parts are formed at the leading and trailing ends of a strip to be rolled and cannot be used as a product. Has been done. When the length of the scrap portion is long to some extent, a method of winding the scrap portion with a winder and discharging it as a scrap coil is often used rather than cutting the end plate. Conventionally, the scrap coil is discharged by manually binding the scrap coil wound by a winder, extracting this small-diameter scrap coil from a reel by a coil car, and loading it on an outlet conveyor or by a crane. It was

The above scrap coil discharging method has a drawback that it is not only workable but also low in efficiency due to the slow operation of the coil car. As a countermeasure against this, a method of clamping both side ends of the scrap coil wound on a tension reel and then transferring the scrap coil from the mandrel to the coil car to band-bond the scrap coil on the coil car (JP-A-3-193215), reel The traveling carriage for processing the scrap coil wound on the reel is arranged so that it can be moved horizontally toward and away from the reel of the winding machine from the rear of the winding machine installation line, and the front end on the traveling carriage is arranged. A machine in which a traverse machine equipped with a binding machine for scrap coils wound on reels and a clamp mechanism for gripping and holding the scrap coils after binding is placed in the section so as to be traversable in the scrap coil removal direction (actual Fair 3-
No. 44326) has been proposed.

[0004]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
In the method disclosed in Japanese Patent No. 215, when the both ends of the scrap coil are clamped, it is necessary to adjust the reel so that the tail end of the coil comes to the stopper position. It becomes large, and it takes time to move to the next work, resulting in low efficiency. Also, the actual fair 3-
In the device disclosed in Japanese Patent No. 44326, banding is performed while the scrap coil is wound on a reel, and therefore the line must be stopped during that time, which not only causes a reduction in efficiency but also the thickness of the scrap coil. If it is thin, the spring coil is small and it is difficult for the scrap coil to come off the reel. Further, when the scrap coil is gripped from the outer periphery and clamped, the scrap coil is easily crushed and sometimes cannot be clamped well.

An object of the present invention is to solve the above-mentioned problems of the prior art and to provide a scrap coil processing apparatus capable of automatically processing scrap coils up to binding without disturbing the winding shape of the scrap coils.

[0006]

[Means for Solving the Problems] The present inventors have conducted various test studies in order to achieve the above object. As a result, a scraper coil dislocation prevention and positioning stopper, a clamp mechanism, and a scrap coil squeezing mechanism are mounted on the transport carriage, and the scrap coil wound on the reel is directly extracted from the reel and transferred onto the transport carriage. Then, after adjusting the scrap coil packaging on the carrier, it is clamped, banded by a binding machine, released by unclamping and transported by the carrier so that it can be bundled offline without disturbing the winding shape. The present invention has been accomplished by discovering that scrap coils can be automatically processed and scrap coils can be processed without disturbing the production efficiency of the strip rolling line.

That is, according to the present invention, in a device for treating scrap coil remaining on a reel of a strip rewinder or a winder, a turning roller for rotating a scrap coil placed therein and an inner surface of the scrap coil are divided. A carrier truck equipped with a scrap coil winding and tightening mechanism consisting of a press roll, a scrap coil edge positioning stopper, and a coil clamp mechanism, a turntable laid on the track of the scrap coil mounting position of the carrier truck, and a carrier truck track It is a scrap coil processing device comprising a binding machine installed above.

By rotating it, the winding shape of the scrap coil is adjusted. After that, the edge positioning stopper is tilted to adjust the coil edge and the coil edge is positioned. Then, the scrap coil is clamped by the coil clamp mechanism so that the disorder of the winding shape when the scrap coil is transferred from the reel to the carrier is adjusted, and the coil can be always in a stable winding state.

Further, according to the present invention, since the turntable is laid on the track of the scrap coil mounting position of the carrier, when the scrap coil extracted from the reel is mounted on the turning roller divided into a plurality of parts. The turntable can be rotated and placed according to the orientation of the scrap coil, and it is not necessary to control the orientation of the scrap coil. Furthermore, in the present invention, while dividing the turning roller into a plurality,
By installing the binding machine installed on the orbit of the transport carriage, the arm of the binding machine can be inserted between the turning rollers and the scrap coils can be band-bound on the transport carriage. The band-bonded scrap coil can be transported to the scrap yard with a carrier after the clamp is released, but it is used to transfer the scrap coil from the carrier to a predetermined position on a roller conveyor or the like. It is efficient to install a transfer machine and convey the scrap coil to the scrap yard with a roller conveyor.

In the present invention, when the scrap coil extracted from the reel is placed on the turning roller divided into a plurality of pieces, the scrap coil is extracted from the reel using a lifting magnet or the like and transferred to the turning roller of the carrier truck. However, the hanging tool is not limited to the lifting magnet, and any method may be used as long as the coil does not collapse even if the coil is thin. In addition, the scrap coil placed on the turning roller of the carrier is provided with the guides of the upward spread on both sides orthogonal to the axial direction of the scrap coil, so that the scrap coil can be easily placed on the turning roller.
