Description

[Detailed Description of the Invention] The present invention relates to a coil skid, and is particularly adapted to be able to load even small-diameter coils.

For example, in steel manufacturing companies, a fixed coil skid is generally installed in front of a processing line such as a rolling mill or a continuous annealing furnace. The coils are loaded in the order of processing, and the coil car picks up the coil on the skid and attaches it to the uncoiler mandrel.
This prevents processing from stopping due to a delay in coil supply.

In addition, the fixed coil skid has two rod-shaped members with coil support surfaces spaced apart at an appropriate distance to prevent the coil from falling off the skid and to load the coil with the coil core aligned with the axis of the uncoiler. They will be installed in parallel. The coil placed on such a fixed coil skid is installed on the inlet side of the preprocessing line by a coil car etc.
Then, it is attached to the empty uncoiler mandrel by a coil car or the like.

On the other hand, the outer diameter of coils has been increased in recent years with the aim of reducing manufacturing costs, and the bars of fixed coil skids are fixed at appropriate intervals so that large-diameter coils can be stably loaded. has been done. However, it is unavoidable that small-diameter coils that are smaller than the spacing between the rods of a fixed coil skid will occasionally occur due to processing line malfunctions or the like.

Previously, when a small diameter coil like this occurred, it was dealt with by loading it directly onto the coil car and leaving it on standby. When a small diameter coil is selected and must be loaded onto the coil car, or when a strip being processed on the processing line must be stopped midway through and the coil installed on the uncoiler mandrel must be removed. However, the coil car could not be used, which caused a delay in the supply of coils to the processing line, resulting in the processing line being shut down.

The object of the present invention is to provide a coil skid which eliminates the above-mentioned drawbacks and is capable of mounting small-diameter coils.

Embodiments of the present invention will be described with reference to the drawings. In the figure, 1 is an uncoiler mandrel, 2 is a coil unwinding machine installed on the floor, and processing line A-A.
The uncoiler mandrel 1 extends in a direction perpendicular to the uncoiler mandrel 1. 10 is a coil car, 3 is a lifting device (for example, a hydraulic cylinder) provided on the coil car 10, 4 is a lift frame provided in the moving part of the lifting device 3, 5 is a cradle roll provided on the lift frame 4, and 6 is a large diameter A fixed coil skid on which coil C1 is placed is shown. Reference numeral 7 denotes a movable coil skid, on which a small diameter coil C2 is placed, and is provided below the fixed coil skid 6 so as to be movable forward and backward. Reference numeral 8 denotes a movement device (for example, a hydraulic cylinder), which is connected to the frame of the movable coil skid 7 with a pin. A roll 9 is rotatably provided at the tip of the movable coil skid 7, on which the small diameter coil 2 is placed.

Next, an example of the operation of the present invention will be explained.

Now, when transferring the small diameter coil C2 onto the skid shown in FIG.
The advancing and retracting devices 8 of all the movable coil skids 7 on which the movable coil skids 7 are placed are operated to cause the left and right movable coil skids 7 to protrude.

Then, the small diameter coil C2 is placed on the movable coil skid 7 using a crane or a forklift (not shown). Next, in order to attach the small diameter coil C2 placed on the movable coil skid 7 to the uncoiler mandrel 1, a horizontal movement device (not shown) is activated to move the coil car 10 to the position where the large diameter coil C2 is placed. The coil car 10 is stopped when the center of the coil seat is aligned with the center of the coil C2. Next, the lift frame 4 of the coil car is raised to such an extent that the cradle roll 5 of the coil car touches the bottom surface of the protruding movable coil skid 7. Then, the movable coil skid advancing/retracting device 8 is activated, and the roll 9 provided at the tip of the movable coil skid is slowly retreated along the bottom surface of the small diameter coil C2 in a direction in which the interval between the rolls 9 is widened. As a result, the small diameter coil C2 gradually descends and is finally mounted on the cradle of the coil car 10. Next, the lift frame 4 of the coil car 10 is raised, the coil car 10 is moved horizontally toward the uncoiler mandrel, and is stopped in front of the uncoiler mandrel. Next, small diameter coil C
After cutting the second band and aligning the center of the small diameter coil C2 with the center of the uncoiler mandrel 1, the small diameter coil C2 is attached to the uncoiler mandrel 1.

As described above, in the present invention, by arranging the movable coil skid 7 below the fixed coil skid 6, it is possible to smoothly attach the small diameter coil C2 to the uncoiler mandrel 1, resulting in efficient equipment. It can be said that.
