Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arrangement of equipment on the rear surface of a cold rolling mill for discharging a coil steel sheet wound on a tension reel device to the outside of the rolling equipment.

[0002]

2. Description of the Related Art A steel plate strip continuously fed through a rolling mill is wound around a tension reel mandrel in a coil shape.
It is removed from the tension reel mandrel by the coil car and is carried out to the storage yard outside the rolling facility or the next process line using a crane or a conveyor device.

On the other hand, the part to be removed as scrap or the leader strip is also wound up by the tension reel device and then carried out of the equipment, but the amount thereof is much smaller than that of the product coil. The processing work related to unloading was done manually.

[0004]

By the way, since the scrap coil and the leader strip have a small winding amount, they may be loosened due to the elasticity of the material itself, or the ends may jump up, which makes the handling difficult. Tended to be. Therefore, a binding band is hung around the tension reel device before it is detached from the tension reel device, but this is not only a dangerous work, but also a factor that reduces work efficiency.

The present invention has been devised in order to eliminate such disadvantages of the prior art, and its main purpose is to:
In particular, it is an object of the present invention to provide a rear surface equipment layout of a cold rolling mill configured to improve the handling of scrap coils or leader strips.

[0006]

According to the present invention, such a purpose is to provide a tension reel device for winding a steel strip continuously fed through a rolling mill into a coil, and the tension reel device. A cold car having a coil car for loading and moving the coil removed from the equipment, and a transfer area for transferring the coil on the coil car to a transfer device for carrying the coil out of the facility. In the equipment layout on the rear surface of the rolling mill, the traveling rail of the coil car is extended in a direction orthogonal to the pass line of the strip, and the tension reel device and the transfer area in the traveling rail are provided. At a middle position, a binding device for binding the coil on the coil car and a scrap coil or leader strip are dispensed, and A conveying device for output is achieved by providing a surface facility located after the cold rolling mill, characterized in that arranged adjacent to each other.

[0007]

With this structure, the scrap coil or the leader strip can be processed on the coil car, and the binding band can be hung by using the binding device common to the product coil. Can promote the automation of the processing work.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described in detail below with reference to specific embodiments shown in the accompanying drawings.

FIG. 1 shows the rear equipment of a reversible cold rolling mill constructed according to the invention. This equipment consists of a rolling mill 2 sandwiched between a left-side tension reel device (not shown) and a right-side tension reel device 1 (not shown). 3 is reciprocated a plurality of times to finish to a predetermined thickness.

This equipment comprises a tension reel device 1 for winding a strip 3 continuously fed from a rolling mill 2 into a coil, and a sleeve charger for mounting a sleeve 5 on a mandrel 4 of the tension reel device 1. 6, a belt wrapper 7 for winding the starting end of the strip 3 around the mandrel 4 or a sleeve 5 mounted on the mandrel 4, and a coil car 8 for loading and transporting the coil removed from the tension reel device 1. ing.

The traveling rail 9 of the coil car 8 is extended in a direction orthogonal to the pass line of the strip 3, and a coil carrier (not shown) for carrying the product coil to a storage yard (not shown). The traveling rail 10 on which the vehicle runs is connected to the terminal end thereof, and the coil skid 11 for temporarily transferring the product coil from the coil car 8 is on standby at the connection portion.

At the intermediate position between the tension reel device 1 on the traveling rail 9 for the coil car and the starting end of the traveling rail 10 for the carriage, a dispensing device 12 and a dispensing device for dispensing the scrap coil or leader strip on the coil car 8 are provided. A carrying device 13 for carrying out the scrap coil or the leader strip taken out and a bundling device 14 for bundling the coils on the coil car are arranged adjacent to each other. A marking device 15 is arranged at the end of the coil car traveling rail 9.

Next, the operating procedure of this equipment will be described.

The strip 3 rolled by the rolling mill 2 is
After being wound into a coil, the coil car 8 is loaded and laterally held and moved. During this movement, the binding device 14
After being bound by, and marked by the marking device 15, the coil car 8 is transferred onto the coil skid 11 waiting at the end of the traveling rail 10 for the coil carrier. Then, the product coil is carried out together with the coil skid 11 to the storage yard by the coil carrier.

On the other hand, scrap coils and leader strips are wound on the tension reel device 1 and transported by the coil car 8 like the product coils, but are bound and bound by the binding device 14 like the product coils. It is delivered by the delivery device 12 onto the transfer device 13 disposed adjacent to the device 14, and is delivered to the scrap storage site by an overhead crane (not shown) equipped with a scrap clamp.

[0016]

As described above, according to the present invention, it is possible to fully automate the work of carrying out the scrap coil or the coil including the leader strip, so that the manual work can be greatly reduced and the work It has a great effect on improving safety. Moreover, since product coils and scrap coils or leader strips can be bound together using a common binding device, high space efficiency can be obtained.
