Abstract

PURPOSE:To securely enable taping, by temporarily stopping the rotation of wire coil and sticking an adhesive tape breadthwise from the lower side at the tail end with an adhesive margin left and thereafter rotating the wirecoil again to stick the left adhesive margin and the packing material by the own weight of coil. CONSTITUTION:Dummy rolls 14 having the same outer diameter with a wire coil 10 are arranged at both sides of the wire coil to position at the same level therewith. The wire coil 10 is synchronously rotated at the same peripheral speed with the dummy rolls 14 by a rotary device 15 of dummy roll to wind up the packing material 13 on the outer periphery of wire coil 10. The rotary movement of the wire coil 10 is temporarily stopped and a tape is stuck on the tailend of the material with an adhesive margin left as long as a half of the tape width from the lower end. After that, the wire coil 10 and the dummy roll 14 are rotated again to wind up the packing material on the whole face of the outer periphery of the wire coil 10. Finally, the left adhesive margin and the packing material are stuck and fixed by the own weight of the wire coil 10. Accordingly, secure taping on the material end can be obtained.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic packing method for wire coil.

[0002]

2. Description of the Related Art Conventionally, a wire rod that has been wound into a coil, bundled and bundled and cooled is temporarily stored in a warehouse or an inventory area after being hot-rolled and then shipped to customers from here. Since the wire rod coil that has been weighed, etc. is susceptible to scratches and the like due to the contact of the coils of each other, during transportation within the factory and stacking, cargo and sea transportation by sea freight shipped from the factory During land transportation by automobile, wire flaws during cargo handling, product flaws during stacking, and scratches on the surface of the product occur. Particularly in recent years, as the quality of products becomes higher, surface flaws and the like during transportation have come to be considered to be a problem, and for that reason, packaging has become necessary. As a countermeasure, despite the heavy work such as preparation of materials, winding, folding, and bundling of the wire rod in order to perform the packing work, the packing work of the wire coil is actually done manually. Is.

[0003]

For this reason, the inventors of the present invention have proceeded with the development of a technique for automatically bundling wire coils and packing them as proposed in Japanese Patent Laid-Open No. 5-32210. However, there is a problem in that moisture proofness cannot be ensured unless the taping of the packaging material is performed with certain taping, and the arm is caught when binding or lifting the crane.

[0004]

SUMMARY OF THE INVENTION As a result of intensive development by the inventors who should solve the above problems, the present invention has been completed. The wire rod coil is placed on the cradle roll and the wire rod coil is wrapped with a packing material having a width dimension wider than the wire rod coil width while rotating the wire rod coil,
After that, in the wire coil automatic packing method in which the excess part of the material is narrowed down and pushed into the inner diameter part of the wire coil, the tail end of the material is detected before wrapping when the wire coil is wrapped, and the rotation of the wire coil is temporarily stopped to stop the tail of the material. The adhesive tape is attached to the end from the lower side leaving an adhesive margin in the tape width direction, and then the wire coil is restarted to bond the remaining adhesive margin and the wrapped packaging material by the weight of the coil. There is a wire rod coil automatic packing method.

The present invention will be described in detail below with reference to the drawings. FIG. 1 is a sectional view of a tail end taping device according to the present invention. In the device of the present invention, as shown in FIG. 1, the tail end taping carriage (I) 1 and the tail end taping carriage (II) 2 are driven by the traveling drive motors 3 and 4 to form the tail end taping carriage (I) 1 and the tail end taping carriage (I). II) It is configured so that 2 runs and taping is done with the adhesive margin of about half the tape width left. Reference numeral 5 is a material holding bar,
This material holding bar 5 is installed so as to hold the material at the time of taping so as to come to the upper surface of the traveling position of the tail end taping carriage (I) 1 and the tail end taping carriage (II) 2.
The non-contact material of the tape is used because about half of the adhesive surface of the tape is in direct contact. Further, it is configured to rotate by the actuator 6 for rotating the material upper surface holding bar, retract when passing the material upper surface, and press and fix the material tail end from the upper surface.

FIG. 2 is a detailed view of the tail end taping device according to the present invention. As shown in FIG. 2 (A), the material pressing bar 5 is configured to be rotatable by 180 ° between the retracted position when the material passes and the material upper surface pressing position when the tail end taping is performed. The entire length in the width direction of the tail end of the material for preventing the material from curling or wrinkling is clamped and fixed between the material supply table 12 and the material lower surface holding clamp 8 as shown in the enlarged view of FIG. 7
Is pressed from the lower surface, and when the tape pressing roll 9 moves while taping, the material end is fixed so that the material does not turn over or wrinkle.

FIG. 3 is a perspective view showing a state in which the packaging material is tail-taped. As shown in FIG. 3, the material winding state in which the packaging material 13 is wound around the outer peripheral surface of the wire rod coil 10 is shown. The dummy roll 14 is the wire rod coil 10.
Are arranged on both sides in the height direction and are set to have the same outer diameter as the wire rod coil 10. The dummy roll rotating device 15 rotates the wire coil 10 in synchronism with the peripheral speed, so that the packing material 1
3 is wound around the outer peripheral surface of the wire coil 10.

The dummy roll 14 is provided with a gripping mechanism (not shown) for the packing material 13, and the packing material 13 rotates above the taping device 11 or 180 ° and passes above the material upper surface holding bar 5 in the retracted position. As described above, the gripping mechanism of the packaging material 13 is automatically supplied. While holding the tip of the automatically supplied packing material, the dummy roll 14 is rotated by the dummy roll rotating device 15 in synchronization with the peripheral speed of the wire rod coil 10 to wind the packing material 13 around the outer peripheral surface of the wire rod coil 10. In the process, when the tail end of the packaging material 13 is detected by the material tail end detection sensor (not shown), the dummy roll 14 that has been rotating in synchronization with the peripheral speed of the wire rod coil 10 stops rotating together with the wire rod coil 10. . At this time, the tail end of the packing material is set so that it comes to about half the width direction of the taping device. Then, the material upper surface holding bar 5 is rotated 180 ° from the retracted position to the material upper surface holding position above the taping device 11, and at the same time, the entire length in the material tail end width direction is sandwiched and fixed between the material supplying table 12.

Next, the material lower surface holding clamp 8 is lifted up, and the material tail end is sandwiched and fixed between the material upper surface holding bar 5 and the material upper surface holding bar 5 to prevent wrinkles due to the displacement of the packing material 13 due to taping. Then, the tail drive taping cart (I) 1 and the tail taping cart (II) are driven by the traveling drive motors 3 and 4.
Run 2 and attach the tape from the bottom to the tail end of the material leaving an adhesive margin of about half the tape width. After attaching the tape, the material upper surface holding bar 5 and the material lower surface holding clamp 8
Is evacuated, and the wire coil 10 and the dummy roll 14 are rotated again to wrap the packing material around the entire outer circumference of the wire coil. To fix the tail end of the material, the adhesive margin that remains about half of the pasted tape is trampled by its own weight as the wire coil rotates, and is adhered to the already wrapped packaging material to fix the tail end of the material. The packing of the outer peripheral surface of the wire rod coil 10 is completed.

[0010]

As described above, according to the present invention, the taping of the material tail end can be surely performed, and therefore the moisture proof property can be secured, and all the problems of binding and catching at the time of lifting the crane are solved.
