Description

The present invention relates to an attachment exchanging apparatus for exchanging an attachment for changing a reel diameter by using a coil conveying means. Here, the coil conveying means is used when conveying the coil removed from the reel or supplying the coil to the reel.

Conventionally, when a steel strip is wound on a reel to form a coil, the inner diameter of the coil is adjusted according to the demands of the customer. For this reason, the outer diameter of the reel is adjusted by attaching an attachment for changing the reel diameter, in which a plurality of arc-shaped segments in a cross-sectional view are connected in a cylindrical shape outside the reel where the maximum diameter when expanded is constant To be done. When attaching or removing the attachment, the operator expands or contracts the reel, and then inserts and removes the saber-like stopper into the groove between the segments. Therefore, in order to efficiently perform attachment and removal operations, an attachment replacement device using a coil car is disclosed (for example, see Patent Document 1).
