Here, the groove, as shown in Figure 5 (a), is formed radially long relative to the shaft hole 32, or as shown in Figure 5 (b), the main body 30A It is sufficient that the grooves 34A become increasingly closer to the axial hole 32A or vice versa with respect to the clockwise or counterclockwise direction centering on the axial hole 32 formed therein.

The shaft hole 32 is fitted with a shaft 40 formed to be long in size with both ends exposed to both sides of the main body 30, the outer diameter size of the shaft 40 is slightly smaller than the inner diameter size of the shaft hole 32 Since the shaft 40 is formed to be small to be rotated in the axial direction in the state accommodated in the shaft hole (32).                     

Rotators 50 having the same number of wings 52 as the number of the grooves 34 are fixedly installed at both ends of the shaft 40, and the wings 52 are centered on the shaft 40. It has a shape bent in one direction of the clock or counterclockwise. In addition, the threads 52a are formed in the wings 52 of the rotating body 50 fixed to the upper end of the shaft 40 along the bent shape.

Each of the grooves 34 are fitted with rods 60 each having a length formed such that both ends thereof are exposed to both sides of the main body 30, and the rods 60 preferably have a circular cross section. The outer diameter size of 60 is set such that the rod 60 is movable along the groove 34 and capable of axial rotation. In addition, the length of the rod 60 is appropriately set so that the lower end thereof passes through the magnet 20 and extends to the lower end of the inner diameter portion of the coil product C.

A gear 62 is formed at an upper end of the rod 60 to be engaged with a thread 52a of the blade 52, and a rod 60 is caught at an upper end of the blade 52 at an upper end of the gear 62. A flange-shaped jaw 64 is formed to prevent it from falling.

In addition, each of the rods 60 inserted into the grooves 34 is elastically supported by the springs 37 so as to move toward the shaft hole 32, and more preferably, the rods at the front end of the springs 37. A support member 36 having a ball shape that does not interfere with the axial rotation of the 60 or a shape surrounding the outer surface of the rod 60 is mounted, and the support member 36 is mounted on the rod 60. It may be configured to be in contact with the outer surface.

A cap 70 having a ring shape surrounding the rotating body 50 positioned at an upper end thereof is fixedly installed at an upper end of the main body 30, and connected to the rotating body 50 positioned at an upper end of the main body 30. The rod 54 is integrally fixed, and the connecting rod 54 is radially elongated through the through hole 72 having a predetermined length in the circumferential direction in the cap 70.

The operation of the present invention having the above configuration will be described.

The device of the present invention can be used as mounted on the magnet crane or directly used in the coil product without any other device. In the latter case, the drive motor 80 is the main body 30 or the cap 70 or the like. Is mounted. Here, the case where it is used with this apparatus attached to a magnet crane for convenience is demonstrated.

In order to prevent the inner peripheral portion of the coil product C from being loosened using the apparatus of the present invention having the configuration shown in Figs. 3 and 4, first, the coil product C is placed so that the smooth one end is placed on the floor. By operating the ceiling crane, the magnet 20 is moved to contact the upper end of the coil product (C).

At this time, the device of the present invention is the power supply to the drive motor 80 is cut off because the rod 60 is moved inward along the groove 34 by the force of the spring 37 the rod 60 is a coil product It may be inserted into the inner diameter of (C).                     

Thus, the magnet 20 is seated on the upper end of the coil product (C), the power is applied to the drive motor 80 to rotate and drive the pinion gear 84 connected to the drive motor 80 is rotated, and thus The rotating body 50 is rotated by the rotation of the pinion gear 84 and the operation of the rack 56 engaged with it. Of course, since the rotating bodies 50 located above and below the coil product C are integrally connected by the shaft 40, these rotating bodies 50 behave the same.
