Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for packaging a thin metal sheet manufactured by a rolling mill into a coil, and for packaging the inner periphery of the metal coil. This invention relates to a device for taping overlapping stitches.

[Conventional technology]

When winding the metal sheet manufactured by a rolling mill into a coil shape and packing the metal coil sent along the conveyance line, "Steel Handbook Volume 1 Rolling Foundation/Copper Plate" (December 20, 1980) As described on page 692 (Separate issue 3), inner paper, outer paper, outer plate, inner pad,
It is necessary to apply various types of packaging materials such as outer pads, side plates, and outer circumferential plates to the metal coil.

Among these operations, for wrapping the inner periphery of a metal coil, an apparatus such as that described in Japanese Patent Application Laid-Open No. 60-172610 has been developed.

The inner circumferential paper applied to the inner circumferential surface is fixed at a predetermined location by taping the folded edges in the axial direction of the metal coil. However, since the inner peripheral space of the metal coil is narrow, a taping device that can penetrate into the space has not been put to practical use. Conventionally, when taping the overlapped seams, a worker is placed on both sides of the metal coil, and the worker stretches the tape around the inner circumference of the metal coil, and then manually taps the overlapped seams from both sides. It was done by

[Problem that the invention seeks to solve]

However, such manual work has a problem in terms of uniformity of work. For example, P-kneading is required to perform taping so that excessive tension is not applied or wrinkles are not generated in the applied tape. Furthermore, since a plurality of workers are required for one taping operation, there is also a problem in terms of economy.

Further, even if an attempt is made to simply automate the taping work, since the size of the metal coil to be processed varies over a wide range depending on the user's requests, etc., it is necessary to perform taping on different circular arcs. but,
Such a versatile taping device has not been developed so far.

Therefore, the present invention is capable of attaching tape to the inner paper without tension or slack, even for metal coils whose sizes vary over a wide range, without having to manually tape the overlapped seams of the inner paper. The purpose of the present invention is to provide a taping device that can perform

Means for Solving Problems c] In order to achieve the objective, the taping device of the present invention has the following features:
A device for taping the folds of inner circumference paper applied to the inner circumference of a metal coil, comprising: a suction cylinder that is movable in and out of the inner space of the metal coil and whose thickness can be freely adjusted;
A plurality of holes for tape adsorption provided in the wall of the adsorption cylinder on the side opposite to the overlapped seam, and a pressure roll attached to the cylinder provided at the front end of the adsorption cylinder. It is characterized by

Hereinafter, features of the present invention will be specifically explained with reference to embodiments shown in the drawings.

FIG. 1 is a front view schematically showing the taping device of this embodiment.

The taping device is provided so as to be able to move forward and backward along the axial direction of the metal coil 2 placed on the stand 1. That is, in order to attach the tape 3 to the overlapped portion of the inner circumferential paper attached to the inner circumferential surface of the metal coil 2, one end of the tape 3 is clamped by the clamp 4, and a fixed length of the tape 3 is attached by driving the pinch roller 5. is played out from reel 6. The cart 7 on which the cutter 8 and reel 6 are placed is moved away from the metal coil 2 by the length necessary to unwind the tape 3.

The tape 3, which has been let out by the required length, ie, the width of the metal coil 2, by the retreat of the cart 7, is cut by the cutter 8, and transferred to the suction cylinder 9 by the lifting of the clamp 4 and the cart 7.

213,...21. The cylinder boom 22 has a negative side, and a hollow loft 23 is slidably disposed inside the cylinder boom 22. These cylinder boom 22 and rod 23 are guided along a predetermined trajectory by ridges 24 and 25, respectively. The interior space 26 of the loft 23 is also connected to a vacuum source (not shown).

That is, the holes 21, 21□ of the cylinder boom 22 are cut according to the length of the tape 3 cut by the cutter 8.
, 213. ...21. , are opened and closed by a rod 23. Then, as the clamp 4 and the carriage 7 rise, the hole 2
1.21□, 21ff, ...21. , the tape 3 carried to the cylinder boom 22 on the forming side is transferred from the cart 7 side to the cylinder boom 22 and adsorbed.

An upper pedestal 10 supporting the suction cylinder 9 is moved up and down by a lifting device 11 so that the suction cylinder 9 matches the height of the metal coil 2 . This vertical movement can be adjusted by providing an appropriate measuring device (not shown) for detecting the inner circumferential position of the metal coil 2 and according to the detected value from the measuring device. Alternatively, it is also possible to obtain information regarding the size of the metal coil 2 wound in the metal sheet coiling process and adjust the vertical movement based on that information.

Furthermore, the suction cylinder 9 is moved forward to the other end position A of the internal space of the metal coil 2 by the drive of the motor 12 . The other motor 13 is used to adjust the degree of penetration of the rod 23 into the cylinder boom 22.

FIG. 2B is a view seen from the axial direction of the metal coil 2. FIG. In addition, in the same figure, two types of metal coils 2a and 2b with different diameters are shown at the same time to show that the taping device of this embodiment is applicable to metal coils 2 of various sizes.

The metal coil 2 is placed on the stand 1 with the overlapped seam 41 of the inner circumference 40 facing down. The suction cylinder 9, which is suctioning the tape 3, is pushed to the other end position A of the internal space of the metal coil 2. Then, the suction cylinder 9 is lowered and the tape 3 is linearly aligned on the overlapped seam 41. Next, the hole 21. , 21□□214. ... 21.1 is opened and air enters the cylinder boom 22, the tape 3 is released from vacuum suction to the cylinder boom 22 and moves to the overlapped seam 41 of the inner paper 40.

Then, the pressure roll 43 attached to the tip of the rod of the cylinder 42 provided at the front end of the cylinder boom 22 is attached to the tape 3 that has been transferred onto the overlapped seam 41.
