The present invention relates to an iris plate driving device of a wire winding machine that raises a guide cone for rotation of a mandrel when the wire rod is integrated into a mandrel in a coil manufacturing process in a wire coil manufacturing method. The present invention relates to an iris plate driving apparatus of a wire winding machine that is improved to allow the coil to be integrated in a good shape by moving upward and downward in the process of raising and lowering, and to maintain a stable balance upon falling of the coil.

Generally, as shown in FIG. 1, as shown in FIG. 1, a wire rod 210 formed of a rod through a rolling process 200 passes through a head portion 212 and spirally coils 214. It is wound into a coil winding machine 220, which is conveyed to the coil winder 220 through the coil conveyor 216, where the linear wire rods, which have been elongated and moved as a ratio, are integrated into a coil form of a mass.

In the shipment process of such a wire rod product, the conventional wire coil winding machine 220 has a structure as shown in FIG. 2. That is, the coil winder 220 is provided with a plurality of mandrels 262a and 262b disposed at approximately 90 degrees, and they rotate about the rotation axis 264, and in this case, one mandrel ( 262a maintains the horizontal direction, and the other 262b maintains the vertical direction. When the mandrel 262b is in the vertical direction, the coil 214 is dropped from the top and spirally integrated around the mandrel 262b, and when the integration is completed, the mandrel 262b that is rotated and completed integration is completed. This horizontal direction becomes empty, and the empty mandrel 262a becomes vertical to receive a new wire rod 214, and the horizontal wire coil 214 in the horizontal direction is separated by the C-hook 222. To be moved to a place.

On the upper side of the mandrel 262a disposed in the vertical direction in the coil winding machine 220, a cone-shaped cone 265 member for guiding the wire coil 214 to the mandrel is located, and the cone 265 A cylindrical tube 267 is disposed outside of the circumference, and an iris plate driving device 270 for raising and lowering the cone 265 and the tube 267 up and down is provided. Accordingly, when the iris plate driving device 270 completes the integration of the wire coil 214 and rotates the mandrel 262a and 262b, the iris plate driving device 270 raises the cone 265 and the tube 267 to raise the mandrel ( When the mandrel 262a is rotated so that the empty mandrel 262b is positioned at the lower side, the cone 265 and the tube 267 are moved to the upper side of the mandrel 262b. By lowering, the wire coil 214 is integrated in the mandrel 262b in a stable state.

However, the conventional iris plate driving device 270 as described above has a pivot shaft 272 at one end as shown in FIGS. 3 and 4 so that the tube 267 is mounted on the rotatable frame 274. It is fixed, the cone 265 is disposed inside the tube 267, the other side of the frame 274 is provided with a lifting cylinder 280 for lifting the frame 274. In addition, a plurality of iris plates 282 movable in a horizontal direction from the lower side of the tube 267 and a plurality of drive cylinders 284 for rotating the iris plate 282 on the frame 274 will be.

In addition, the wire coil 214 continuously moves into the space between the cone 265 and the tube 267 in the state where the cone 265, the tube 267, and the frame 274 are tilted and raised. In this process, the conventional coil winding machine 220 had various problems.

In one of them, the cone 265 and the tube 267 are inclined so that the distribution of the wire coil 214 stacked in the space therebetween is not uniform in the circumferential direction and is biased to either side. Non-uniformity occurs. Next, the rotation of the mandrel 262a and 262b is completed, and the cone 265 and the tube 267 are lowered, and the coil 214 of the state temporarily integrated in the space therebetween is the mandrel ( When the iris plate 282 is opened in the horizontal direction to fall to the 262a) and 262b, the opening direction is made horizontal so that friction with the wire rod on the upper surface thereof causes the wire rod to be drawn, and the mandrel 262a ( The shape of the wire coil 214 falling to 262b is disturbed.

In addition, in the conventional iris plate driving device 270, the wire coils 214 collide with the inclined surface 292 of the upper gate 290 of the mandrel 262a and 262b due to various factors as described above. As a result, a defect occurs on the surface of the wire coil 214 or the wire coil 214 is caught on the inclined surface 292. Thus, the mandrel 262a (a 262b), various surface defects are generated even between the wire coil strands, and excessive crushing or the like is caused when binding to the band 230 or the like in a later process, resulting in production failure.

The present invention is to solve the conventional problems as described above, the purpose is to ensure that the wire coil is always integrated in the mandrel in a good form, and to maintain a stable balance during the fall of the wire coil to prevent surface defects of the wire coil In addition, the present invention provides an iris plate driving device of the wire reel winding machine which is improved to achieve a smooth wire rod production process.
