Description

Apparatus for disassembling a cylindrical sleeve from a payoff reel and transferring the sleeve to a storing place}

The present invention relates to a cylindrical sleeve separation and transfer processing apparatus of a payoff reel, and more particularly, to enable a quick and simple separation of a cylindrical sleeve mounted on a payoff reel and transfer the sleeve to a predetermined storage location. To a cylindrical sleeve separating and conveying processing apparatus of a conventional payoff reel.

In general, the payoff reel provided in the steelmaking facility is used to unwind the coil wound in the form of a roll. The inner diameter portion of the coil is fitted with a hollow cylindrical sleeve depending on how thick the steel sheet is or for other reasons, and the sleeve is mounted to the payoff reel when the coils are all released. Since the coil remains loose, it is necessary to remove the sleeve from the payoff reel after all the coils have been released.

1 is an explanatory diagram illustrating a cylindrical sleeve detaching method of a payoff reel according to the related art, and a sleeve S is separated from the payoff reel 120 using a coil car 110 for carrying a coil.

That is, the coil car 110 mounts the coil to the payoff reel for a rolling operation, and then moves to a preset standby position and waits while all the coils are released so that the sleeve S only has the payoff reel 120. When mounted on the coil car 110 is moved to the front of the payoff reel 120 again to separate the sleeve (S) mounted on the payoff reel 120 to transfer to a predetermined storage location.

However, according to the conventional cylindrical sleeve detachment technique, the coil car 110 does not play a role of carrying the coil and the coil mounted on the payoff reel 120 to process the sleeve S is unrolled. It was undesirable in terms of productivity because it had to wait in the waiting position until.

In addition, when the sleeve S is partially deformed and it is difficult to separate it from the payoff reel 120 or the scrap is inserted into the payoff reel 120 due to various reasons, the scrap S is used to payoff the sleeve S by the scrap. When it is difficult to separate from the operation 120, the conventional coil car 110 does not have a means to solve it by itself has had a problem that excessive work time for the sleeve (S) or scrap processing.

The present invention is to solve this conventional problem, and after the coil having the sleeve is mounted on the payoff reel and the coils are all released, the sleeve can be quickly and simply separated from the payoff reel to be transported to the storage place. It is an object of the present invention to provide an apparatus for separating and transferring a cylindrical sleeve of a payoff reel.
