Conventionally, as shown in FIG. 5, when magnet conveyors 70 and 71 are arranged on the upper side and the lower side and the coil 72 is unwound from the upper side, the coil 72 is magnetically attracted to the upper magnet conveyor 70 while The end portion of 72 is guided to the pinch roll 73, and when the work is completed, the hydraulic cylinder 74 is driven so as to escape to the upper side. When the coil 72 is unwound from the lower side, the tip of the coil 72 is guided to the pinch roll 73 while being magnetically attracted to the lower magnet conveyor 71.

[0003]

However, in the work of unwinding the coil from the upper side, in the case of a coil having a small diameter, since the tip of the coil has a winding tendency, the tip bends downward and magnetic attraction does not occur. There was a problem in that it could not be performed reliably and that it might fall in the middle. Therefore, if the inventor also uses the lower magnet conveyer for surely carrying the unwinding end of the coil on the upper part, the unwinding part of the coil does not drop during the transportation, and further By also using the magnet conveyor of
The present invention has been completed by considering that the apparatus can be simplified. The present invention has been made in view of the above circumstances, and prevents the unwinding end of the coil from falling when the coil is untwisted,
It is an object of the present invention to provide a magnet conveyor for a coil opener, which ensures automatic threading and downsizing of the device.

A fifth roller, whose lower tangent is located at the upper tangent level of the third roller, is attached to the rear part of the movable frame, and an endless belt of a predetermined length is folded back by the fifth roller. When the gantry is retracted, the decrease amount in the vertical direction applied to the fourth roller coincides with the increase amount in the belt length applied to the rear fifth roller. As a result, the movable gantry can be freely moved back and forth within a certain range by using the predetermined endless belt. Further, since a mounting conveyor is formed by a belt that is stretched between the fourth roller and the first roller, and a magnet is arranged in the lower part of the belt, it is possible to remove the magnetic material from the upper part. The unwinding part can be transported smoothly. Particularly, in the magnet conveyor for a coil opener according to claim 2, the contact angle with the belt is large, and the third conveyor is arranged at a fixed position.
Since a drive motor is attached to the roller to form the drive roller, the power transmission force is increased and the attachment structure is simplified.
