DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for mounting a metal sheet coil on an outer peripheral paper.

[0002]

2. Description of the Related Art As a device for folding a peripheral sheet by rotating the coil while supplying the peripheral sheet to a metal plate coil, the applicant has previously disclosed in Japanese Patent Application Laid-Open No. H01-240418 a device which is generated due to a difference in inner and outer peripheral speed of the coil. We proposed a device using a shuttle lever that folds the outer peripheral paper. In FIG. 3, the outer peripheral paper 13 formed in a U-shape is fed to the coil 14 by the paper feeder 1.
While feeding the outer peripheral paper 13 at a constant speed using the belt of the paper feeder. The leading end of the outer peripheral paper 13 coming on the coil 14 is adhered to the coil by the taping device 2, and the coil 14 is rotated by the cradle roll 11.

When the coil 14 rotates, a paper fold 15 is formed on the inner peripheral side of the coil 14 due to the difference between the inner peripheral speed and the outer peripheral speed of the coil 14. The paper folds 15 are driven up by the shuttle motor 3 driven by the drive motor 4, and are sequentially fed to the brush roller 7. The operation of the shuttle lever is determined by the slide device 6. The paper fold 15 fed to the brush roller 7 is pre-folded by the same roller, and then pressed by a press roller 8 having the same structure as the brush roller to form a fold.

Further, the applicant has previously filed Japanese Patent Application No. 05-039.
942 (JP-A-6-255616) ,
We have proposed a device that feeds the outer peripheral paper consisting of the pressing roller at the end of the outer peripheral paper and the belt-shaped flexible guide at the same speed as the outer peripheral surface of the coil. In FIG. 4, a holding roll 30 is provided on a vertically movable frame 16 in parallel with the coil axis, one end of a flexible guide 20 having a desired length 1 is fixed to the frame 16, and the other end is positioned rearward in the coil rotation direction. To hold.

[0005] After the leading edge of the outer peripheral paper is fed to above the coil by the paper feeder 1, the cylinder 18 is operated and the presser roll 30 is moved.
And the guide 20 are simultaneously lowered. Thereafter, when the cradle roll is rotated, the non-driven presser roll 30 rotates together with the coil and feeds the outer peripheral paper at the same speed as the coil outer peripheral speed. The outer peripheral paper can be fed at the same speed as the outer peripheral speed of the coil without the tape bonding.

[0006]

In this arrangement, the outer peripheral surface of the outer peripheral paper is pressed against the outer peripheral surface of the coil within the range of the pressing roll and the flexible guide, and the crease forming of the outer peripheral paper is completed within the pressed range. However, there is no guidance in the range from the point off the flexible guide to the cradle roll point, and the structure is such that the arc is formed along the outer peripheral surface of the coil while maintaining the arc shape of the pleated outer paper. ing.

According to experiments, in feeding the outer peripheral paper from the point off the flexible guide to the cradle roll point,
The leading edge of the outer peripheral paper could not maintain the arc shape due to the crease forming, was linear, did not adhere to the coil, and had folded or wrinkled at the leading edge of the outer peripheral paper when the cradle roll was engaged. After the cradle roll bites at the leading edge of the outer peripheral paper, the U-shape of the outer peripheral paper cannot be maintained due to the restoring force of the fold shape due to the paper rigidity. He had a bad appearance. Further, the rear end portion of the outer peripheral paper has a linear shape similarly to the front end portion, and the formed paper fold shape cannot be maintained, which causes a poor packing appearance. The present invention adheres the outer peripheral surface of the outer peripheral paper to the outer peripheral surface of the coil over the entire length of the outer peripheral surface of the coil,
It is an object of the present invention to provide a method for mounting a metal sheet coil on the outer peripheral paper to obtain a beautiful package without wrinkles or folded package.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. In FIG. 1, an outer peripheral paper 13 which is folded in a U-shape in advance is supplied to an outer peripheral surface of a down-end type metal plate coil 14 placed on cradle rolls 11a and 11b. After the leading edge of the outer peripheral paper reaches the coil, the presser roll 30 and the flexible guide 20 are lowered by an elevating device (not shown), and the presser roll 30 comes into close contact with the coil 14 via the outer peripheral paper. In close contact with the outer peripheral surface of the coil over 1/4 of the circumference.

Thereafter, by rotating the cradle roll, the non-driven presser roll 30 rotates, and the outer peripheral paper 13 is fed along the outer periphery of the coil, and extends from both end surfaces of the coil 14 to the inner peripheral edge of the coil. Paper folds 15 occur. The paper fold 15 is foldd by the shuttle lever 3 and is creased and formed by the brush roller 7 and the press roller 8. The outer peripheral surface of the outer peripheral paper on which the fold is formed passes between the outer periphery of the coil and the flexible guide 20, during which the flexible guide 2
Since it is pressed by its own weight of 0, the state of close contact with the outer periphery of the coil is maintained.

In the outer paper passage range from the end point 20a of the flexible guide to the point of engagement 11c of the cradle roll 11a on the entry side, before the leading end of the outer paper passes through the end point 20a of the flexible guide, Air is jetted from an air nozzle 22 disposed on the front surface at an angle α downward from a horizontal line. Even when the leading end portion of the outer peripheral paper has a linear shape in which the arc shape due to the formation of the paper fold is not maintained, the outer peripheral paper is closely attached to the outer peripheral surface of the coil by air injection, so that it can be smoothly engaged with the cradle roll. Since the air injection from the air nozzle 22 is continued until the trailing end of the outer peripheral paper passes through the presser roll 30, the first half of the outer peripheral surface of the outer peripheral paper is always in close contact with the coil, and even if restoration of the fold shape due to paper rigidity acts. Is maintained.

Next, when the rear end of the outer peripheral paper passes through the presser roll 30, air is jetted at an angle β upward from a horizontal line from an air nozzle 24 disposed on the front surface of the entrance cradle roll 11a. The rear half of the outer peripheral surface of the outer peripheral paper is always in close contact with the coil and the U-shape is maintained, and the air jet is continued until at least the outer edge of the outer peripheral paper passes through the entry-side cradle roll 11a. Even smoothly, it smoothly bites into the entry cradle roll 11a along the coil outer peripheral surface.
No. The air pipe 2 to which the air nozzle 22 is connected
