Description of the Related Art Conventionally, in a line for producing a steel plate, for example, in hot rolling, a hot rolled steel plate is wound into a coil on a take-up reel of a winder at the exit side of a hot rolling mill. This hot-rolled steel sheet is handled in the form of a coil to the processing line of the next step. Then, the coil of this hot-rolled steel sheet is inserted into the rewinding reel of the rewinding machine at the entry side of the processing line,
It is rewound by a rewinder and supplied to the processing line. The steel plate treated here is rewound in a coil shape on the take-up reel of the winder again on the outlet side of the processing line. In such a process, coil handling is performed using a coil car.

置。In order to achieve the above object, the inventors of the present invention have studied in detail the behavior of the coil when the coil falls, and as a result, the running resistance of the coil car increases when the reel and the coil come into contact with each other. Therefore, the change in the running resistance prevents the coil from falling over. The gist of the invention is as follows: (1) In equipment that runs a coil car by a motor, when a coil on the coil car is transferred to a reel, the running current or power of the coil car is always detected and a constant reference value is set.

1, reference numeral 1 is a coil, 2 is a reel, 3 is a coil holder of a coil car, 4 is a coil car carriage, 5 is a coil car running electric motor, 6 is a coil car running load detection device, and 7 is a coil car running control device. Therefore, when the tip of the reel 2 is contacted when the coil 1 is transferred onto the reel 2,
The load on the electric motor 5 for traveling increases as compared with that during constant speed traveling. Therefore, the traveling load detection device 6 detects that the set reference value is exceeded, and the traveling control device 7 stops traveling of the coil car.

い。However, in general, the weight of the coil transferred to the reel is various, and it may not be possible to have a constant value as a reference value. Further, the traveling load during acceleration of the coil car may exceed the load increased when the reel and the coil come into contact with each other. In such a case, it is necessary to take a reference value for each coil to be transferred. The reference value may be set based on the traveling load when the coil car is traveling at a constant speed.

必要がある。EXAMPLE An example of the present invention will be described below with reference to FIG. FIG. 2 is a diagram showing the relationship between running and motor load based on the device shown in FIG. In FIG. 2, P is a traveling load (current or electric power) when traveling at a constant speed, and a constant may be set for this value for each coil weight. Therefore, the electric motor load is generally very large during acceleration simultaneously with the coil car running, and the running load during constant speed running shows a constant value like P when the running continues stably thereafter. After that, when an external cause such as contact between the reel and the coil occurs, a large electric motor load is applied. When it reaches a certain value or more, it is determined that the load is due to the contact between the reel and the coil. In this case, as described above, at least P of the reference values is determined for each coil to be transferred, and P of the reference values is set based on the traveling load when the coil car is traveling at a constant speed. . Further, since the electric motor load may exceed the reference value α × P during acceleration, it is necessary to perform control for stopping the traveling of the coil car only in the section where the reel and the coil may possibly come into contact with each other.

ル１の転倒を防止できた。Therefore, using the coil car, the coil outer diameter is 1500 to 2500 mm and the coil width is 800 to 1200.
As a result of inserting the coil 1 of mm in the rewinding reel 2, the interference caused by the disagreement between the center of the coil 1 and the axis of the rewinding reel 2 causes the fall prevention device as shown in FIG. 2 before the fall of the coil 1. From the actual running current of the coil car, the 12% electric motor load was detected, and it was found that the detection result exceeded twice the set reference value of 6% current during constant speed running. It was possible to prevent the coil 1 from falling over by stopping the traveling of the coil.

上極めて優れた効果を奏するものである。As described above, by implementing the present invention, it is possible to prevent the coil from falling over without adopting a complicated coil car structure.
Even for a coil car that is driven by an existing electric motor, it is possible to exert the effect by making a slight change in control, and it has an extremely excellent industrial effect.
