Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a slip-sheet winding method and apparatus for winding slip paper inserted between inner layers of the coil when unwinding a metal strip coil.

[Conventional technology 1] Metal strips such as stainless steel strips (hereinafter referred to as STONOPS) coils are coated with paper or the like (hereinafter referred to as interleaving paper) as a cushioning material to prevent scratches from occurring due to slippage between the coil layers.
is wound between the inner layers of the coil.

Therefore, when such a strip coil is rewound and processed, the interleaving paper is separated from the strip and wound by a slip-on winder to form an interleaving coil.

When winding up a slip sheet, a common method is to let the tip of the slip sheet hang down due to its own weight, and then manually wind it around the winding shaft of a slip sheet winder.

[Problems to be Solved by the Invention] However, the above method has safety problems and also makes it difficult to automate the line, which is an impediment to labor saving and productivity improvement.

Therefore, several methods have been proposed for automatically winding the leading edge of the slip-sheet around a slip-sheet winder, but these methods have not yet been put to practical use.

For example, as described in Japanese Patent Application Laid-open No. 51-81768, there is a method in which air is blown out of a nozzle to make the leading edge of the slipping paper rise, and the leading edge of the slipping paper is wound around a slipping paper winder, or the leading edge of the slipping paper is mechanically moved. Although methods have been proposed in which the object is guided by gripping the object, it has not been put to practical use.

The present invention has been made in view of the problems of the prior art described above, and it is an object of the present invention to provide a slip-sheet winding method and an apparatus therefor, which are capable of automatically winding slip-sheets.

[Means to solve the problem] The present invention solves the above-mentioned problems.

The method of the present invention involves pressing the latter half of the leader tape winding direction of a double-sided adhesive tape, one side of which is releasably adhered to the leader tape at a predetermined pitch and a predetermined length, against the leading end of the interleaving paper on the strip. While unwinding the strip coil, wind up the J-Goo tape to pull out the slip paper, press the first half of the adhesive tape against the winding shaft of the slip paper winder, and use the adhesive tape to close the tip of the slip paper. This interleaving paper winding method is characterized in that the interleaving paper is wound up after the leader tape is peeled off from the adhesive tape after the leader tape is attached to the interleaving paper winder.

In addition, the device of the present invention that suitably implements the above method includes: (1) an interleaving paper winder for winding interleaving paper; (2) a leader in which one side of double-sided adhesive tape is removably attached at a predetermined pitch and length; With a coil wound with tape.

■A rewinding machine that rewinds the coil.

■A winding machine that winds up the rewound leader tape.

■The leader tape attached to the leader cheap rewinding machine and the leader tape winding machine is energized and kept under tension at all times, and the second half of the adhesive tape is placed on the leading edge of the slip sheet, and the first half is placed on the slip paper winding machine. A cylinder that is sequentially pressed against the coil and attaches the leading end of the slip sheet to the slip paper winder using adhesive tape.

This is a slip-sheet winding device characterized by comprising:

[Function j] In order to reliably capture the leading edge of the slip-sheet and guide the leading end of the slip-sheet to the slip-sheet winder for installation, the present invention uses a leader tape to which one side of double-sided adhesive tape is attached. . In other words, the leading edge of one interleaving sheet is attached to the interleaving paper winder using one side of the double-sided adhesive tape, the interleaving paper is attached to the interleaving paper winding machine, the leader tape is peeled off from the adhesive tape, and then the strip is rewound and the interleaving paper is wound. The interleaving paper can be wound by synchronizing the winding of the winding machines.

Therefore, the present invention can automate the winding of slip sheets.

[Example] The apparatus of the present invention and the present invention will be explained in detail using FIGS. 1 to 4. FIG. 1 is an explanatory diagram of an actual example of the apparatus of the present invention, FIGS. 2 and 3 are explanatory diagrams of the operation of the present invention, and FIG.
) is a partially enlarged view of FIG. 2(a), FIG. 4 is an explanatory view of the leader tape of the present invention, FIG. 4(a) is a plan view, and FIG. 4(b) is a side view.

As shown in FIG. 1, the coil 1 of the strip 2 is attached to a payoff reel I5, and is guided by a pinch roll 16 and a guide 18 and rewound. At this time, the interleaving paper 3 is peeled off from the strip 2 and hangs down along the outer periphery of the coil 1. At that time, the leading edge of the slip sheet 3 is detected by the leading edge detector 7,
The tip position is memorized. On the other hand, the first paper winding device includes a leader tape rewinding machine 13, a leader tape winding machine 14, and a pressing roll 9.11 of the no-darchie 5. It consists of a pressing roll cylinder 10, 12, an interleaf paper winder i6, etc.
The leader tape 5 is always kept under tension.

As shown in FIG. 4, the J-Dachibe 5 has a base tape 5a and an adhesive tape 4, both of which are coated with adhesive on both the front and back surfaces. This adhesive tape 4 has a length of 21 and is attached to one side of the base tape 5a at a pitch of co. Further, 17 is a detection hole for detecting the position of the adhesive tape 4.

FIG. 2 shows the process of guiding the leading end of the slip sheet 3 to the slip sheet winder 6. As shown in FIG.

First, when the leading edge of the slip sheet 3 is detected by the tip detector 7, the payoff reel 15 is reversed to rewind the slip sheet 3 so that the leading end of the slip sheet 3 is on the extension line of the cylinder 10 of the pressing roll 9. On the other hand, the adhesive tape 4 attached to the leader tape 5
The tip position of the tip is detected and memorized by the tip detector 8,

4 and cylinders 10 and 12 to move the pressing rolls 9 and 11 to the payoff reel 1, respectively.
5 and the interleaf paper winder 6, and the rear half of the adhesive tab 4 is
Glue it to the tip of the interleaving paper 3.

In this state, the bay reel 15 is rewound, and the leader tape rewinder 13. By operating the leader tape winder 14 and the slip-sheet winder 6, the leading edge of one slip sheet 3 is guided by the leader tape 5 and moves in the direction of the slip-sheet winder 6. Since the adhesive is exposed in the first half of the adhesive tape 4, the first half of the adhesive tape 4 is adhered to the winding shaft of the slip-sheet winder 6, and the tip of the slip-sheet 3 is wound around the slip-sheet winder 6. By removing the slip sheet 3, the slip sheet 3 can be attached to the slip sheet winding machine 6. As shown in FIG. 3, by operating the cylinders 10 and 12, the pressing roll 9
, 11 respectively as payoff reel 15 and interleaf paper winder ll
from the adhesive tape 4 to the leader tape 5.
After peeling off (returning to the state shown in Fig. 1), the payoff reel 15 and the interleaf paper take-up f'! ! By operating the interleaving paper 16 synchronously, the interleaving paper 3 can be wound up on the interleaving paper winding machine 6.

Although the method for winding up the slip sheet from the tip of the coil has been described above, even if the slip sheet is broken during winding of one slip sheet, the slip sheet can be wound in the same manner.

The adhesive strength of the adhesive tape is to be strong enough to guide one slip sheet to the leader tape, and the adhesive surface with the front slip sheet and the adhesive surface with the winding shaft of the slip sheet winder is stronger than that. increasing the strength.

In the embodiment of the present invention, two cylinders are provided, but
One unit is sufficient.

[Effects of the Invention] The present invention can completely automate the slip-sheet winding operation and has excellent effects in labor saving and efficiency.
