Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel strip coil transfer device. More specifically, when constructing a facility for transporting rolled and wound coils to the next process with a transport carriage, a wide base pit space is not required, and space-saving and efficient coil transport can be performed. The present invention relates to a coil transfer device.

2. Description of the Related Art In a rolling process, generally, after rolling a material,
In many cases, a process of winding the material into a coil by a winding facility and then transporting it to the next step such as a rectifying step, a cold rolling step or a shipping step is adopted. As a means for transporting this coil to the next step, the most common method from the past is a conveyor method in which the coil hole axis is horizontally or vertically placed on a plurality of chains and transferred.
It has been widely practiced as a stable transportation method.

On the other hand, conveyance by a carriage has become popular for the purpose of reducing equipment costs. This is a system in which the coil is transported by a trolley that has at least two pairs of wheels on which rails are laid, and since the main equipment that should be installed in the transportation range is only the rails, the equipment is better than conventional equipment. It is a simple and effective method from the viewpoint of maintenance, and the number of adoption is increasing.

However, when considering the efficient operation of the carrier vehicle, as shown in FIG. 1, the coil 2 carried out from the coil supply line 1 is transferred to the forward route 4 by the carrier vehicle 3.
The transfer route must be looped so that after passing the coil a to the target next process line 5 and then returning to the coil supply line 1 through the return route 4b.

In the case of a hot rolling line, the unloading pitch of the coil is generally 60 to 180 seconds, and the coil to be supplied must be able to be carried to the next process one after another even with the shortest pitch. However, the distance to the next process is generally 10
Since there are many plants with a length of 0 m or more, assuming a speed of 90 to 150 mpm which is a general traveling speed of a carrier vehicle, a single carrier vehicle cannot satisfy the required time cycle. Therefore, when adopting the carriage system, it is necessary to install a plurality of carriages to reduce the time cycle. That is, it can be said that the basic operation method is to circulate the plurality of carriages in the route assembled on the loop and efficiently convey the coil to the next process.

As another method, it is possible to install a plurality of sets of rails that do not form a loop and add a transport route sufficient to satisfy the required pitch. However, in a short pitch line, the number of rail installations also increases in proportion, and an extremely wide installation space is required, so it is inefficient compared to the method of forming a loop. There are not many cases of adoption.

Assuming that the transport route is not looped as shown in FIG. 2, the transport carriage reciprocates on the same transport route from the coil supply line 1 at the transport start point to the next process line 5 at the arrival point. In particular, when a plurality of carriages are installed, they interfere with each other, so that they cannot be transported at the required pitch. Therefore, it is necessary to deliver the coil in the middle of the transportation route, which requires a delivery facility and causes an adverse effect such as an increase in the number of installed units, which makes efficient transportation impossible.

Therefore, when the carriage is used as the transporting means, there is no method for realizing efficient transporting other than connecting the rails in a loop or installing the transporting rails in multiple tracks or more.

However, a large installation space is required in both cases of connecting the rails in a loop and arranging the conveyor rails in more than a double track.
The building area corresponding to the installation space is increased, which leads to an increase in building construction cost. In the case of a line such as a hot rolling line, the pit depth of the transportation route is 2-3 m.
In many cases, the transportation route also requires enormous construction costs, and it was sometimes difficult to adopt the trolley system itself.

Further, when the existing conveyor is converted into a trolley, not only it is necessary to newly excavate the basic pit for the transport route for the return route, but also a problem such as interference with existing equipment occurs. In addition, the construction cost will increase because of the avoidance. Above all, it is assumed that it is impossible to carry in a limited space because it occupies a wide installation space in a plane.

Various space-saving measures have been studied so far to deal with such a problem. For example, Japanese Patent Laid-Open No. 5-3.
Japanese Patent No. 05335 discloses a method of downsizing the bogie and a method of reducing the depth of the pit itself.

[0012]

According to these conventionally proposed methods, the amount of work for building a pit in the installation space can be reduced, but the forward and backward directions are basically different. It still occupies a lot of space, and its feasibility is low because it requires a wide installation space.

Therefore, the present invention has been devised to solve such a problem, and an object of the present invention is to provide a coil transfer device which can efficiently transfer a coil without requiring a large installation space. It was made as.

[0014]

And a second transfer rail installed in a vertical positional relationship with the first transfer rail, and a starting position transfer cart elevating / lowering device for elevating the cart at the coil transfer start position to receive the coil from the previous step. Is a coil transfer device.

[0015]

The present invention has been devised as a means for realizing efficient coil transfer within the range of a one-way plane installation space from the starting point to the arriving point. That is, according to the present invention, it is possible to convey a coil from a starting point to an arriving point, lift up an empty carrier truck after passing the coil to the next process, and return it to the starting point with a rail installed above. A transport loop is constructed in the vertical direction. This allows
In addition to achieving a significant reduction in the installation space in a plane as compared with the conventional one, it is possible to obtain high transport efficiency. Further, it goes without saying that the present invention is widely applicable not only to the hot rolling process but also to the introduction of an apparatus having the same purpose.

[0016]

EXAMPLES Examples of the present invention will be described in detail below. FIG. 3 shows an example of an apparatus configuration example of the present invention. Hereinafter, a case where the coil hole axis is conveyed in a horizontal posture will be described.

First, the coil 2 supplied from the coil supply line 1 is conveyed by the carrier 3 along the rail on the outward path 4a from the starting point A to the arrival point B, and the coil 2 is carried out to the next process line 5. At this time, as a method of delivering the coil to and from the coil supply line 1, a method of using a transfer machine having a coil lifting mechanism utilizing hydraulic pressure or electric power to carry the coil onto a trolley is generally used. There is no problem even if the mechanism of is used. In the description of the present invention, an example in which a fixed coil holder is installed is shown as a simpler method.
The carrier truck is moved into the lower part of the coil loaded on the coil holder, the coil is lifted from the coil holder by the built-in lifting cylinder, and the coil carrier loop is advanced to the starting point A in that state.

As a coil delivery method for unloading the coil to the next process line 5, the unloading method of loading the coil on the coil holder with a trolley is simple as in the coil supply line 1, and the coil arriving point after unloading. Go back to B. Of course, even if transferred by other methods, the object of the present invention,
Not affected by the effect at all.

After the coil is carried out to the next process line 5, the carriage that has returned to the coil arrival point B is automatically loaded on the lifting frame 6. On the elevating frame 6, a forward rail 4a for moving the coil carriage is divided according to the length of the elevating frame so that the carriage can be lifted while being placed on the rail. At this time, a clamping device that is automatically fixed to the bogie body or wheels may be installed so that the bogie is stable. The hoisting frame 6 is hoisted up by a hoisting device 8 installed on the hoisting stand 7, and is connected to the return rail 4b installed on the upper part.

Although several methods can be considered as the configuration of the hoisting device 8, in the example of the present invention, an elevating mechanism using a wire is described. The wire 12 is wound up by rotating the hoisting wire drum 14 by a motor utilizing hydraulic pressure or electric power, and the wire attached to the hoisting frame 6 is hoisted through the pulley 13 and at the same time the hoisting frame 6 is lifted. . At this time, a guide roller or the like may be attached between the elevating frame 6 and the hoisting stand 7 to further stabilize the restrained state in order to make it more stable. Other methods such as pushing up with a hydraulic cylinder from the bottom or pulling from the top with a similar hydraulic cylinder are also effective if the installation conditions allow. It is also possible to use a crane installed in the factory by examining the working conditions.

At the winding position of the elevating frame 6, the return rail 4b connected to the rail installed on the upper part of the elevating frame 6 has a rail according to the length of the elevating frame like the forward rail 4a. It is divided and can be connected while the dolly remains on the rail.

After the connection, the coil carriage advances from the starting point C to the reaching point D on the return rail 4b, and descends the frame 9
Automatically loaded on top. At this time, needless to say, the elevating device needs to descend promptly because the next carriage travels on the outward rail 4a.

Next, the carriage that has advanced to the reaching point D is moved down by the unwinding device 11 installed on the unwinding stand 10 in the reverse order of the hoisting operation. Also, it is obvious that the effect of the present invention is not affected even if the other system is adopted for this hoisting device as well as the hoisting device.

In this embodiment, compared with the belt conveyor type or loop car type coil conveying device of the prior art, it is possible to make the equipment compact, and the device body cost can be reduced by 30%. In addition, since it does not require the installation space of the conventional technology, the cost of building and foundation work can be reduced by 20%. Furthermore, since large-scale civil engineering and construction work is not required, the construction period could be limited to the facility modification period.

[0025]

As described above in detail, according to the present invention in which the transport loops of the transport vehicle are vertically arranged, the installation space of the coil transport device can be suppressed to the minimum necessary.
This is particularly effective when the existing transportation equipment such as the conveyor device that is already installed is modified into a trolley system because the existing basic pit can be used as it is without excavating a new basic pit.
