2. Description of the Related Art For example, a film used in the field of plate making has a light-shielding member provided at both ends of a roll-shaped light-sensitive material in which a long sheet of light-sensitive material is wound around the outer periphery of a core, and a light-shielding leader ( A packaging sheet) is configured as a light-shielding photosensitive material roll wrapped around the outer periphery of the roll-shaped photosensitive material.

In this type of light-shielding photosensitive material roll, for example, as shown in FIG. 49, a disk-shaped light-shielding member (flange member) 2 is attached to both ends of a photosensitive material roll (roll material) 1. , The light-shielding reader 3 is wound,
The end of the light-shielding leader 3 is fixed via a terminal fixing tape 4. Next, both widthwise ends of the light-shielding leader 3 are folded into both ends of the photosensitive material roll 1, that is, the light-shielding member 2 side, and the folded portion is heated and heat-welded. Therefore, both ends of the light-shielding leader 3 and the outer surface of the light-shielding member 2 are in close contact with each other, and the light-shielding photosensitive material roll 5 is manufactured.

By the way, after the light-shielding leader 3 is attached to the end of the photosensitive material roll 1 via the joining tape 6,
The photosensitive material roll 1 is wound around the outer circumference. At that time, in order to automatically manufacture the light-sensitive material roll 1, the light-shielding leader 3 is automatically conveyed to a position where the light-sensitive material roll 1 is attached, and the light-sensitive material roll 1 is rotated to rotate the light-shielding leader 3. Is automatically wrapped.

[0005]

However, when supplying the light-shielding leader 3 to the position where the light-shielding leader 3 is attached to the photosensitive material roll 1, a suction belt, a suction pad, or the like is usually used. There is a possibility that the portion cannot be accurately positioned at the pasting position. It has been pointed out that this causes a decrease in the attachment accuracy of the light-shielding reader 3.

In addition, the light-shielding leader 3 is the photosensitive material roll 1
When the photosensitive material roll 1 is rotated after being attached to the end of the above, the light shielding reader 3 may meander. For this reason, there is a problem in that the light-shielding reader 3 wound around the outer periphery of the photosensitive material roll 1 is likely to be misaligned.

The present invention solves this kind of problem, and a method of packaging a roll-shaped article which allows a packaging sheet to be satisfactorily and efficiently wound around the outer periphery of the roll-shaped article with a simple process and structure. And to provide a device.

[0008]

In the method and apparatus for packaging a rolled product according to the present invention, the end portion of the packaging sheet is gripped and conveyed, the packaging sheet is positioned at the winding position, and then the packaging sheet is placed. Is attached to the end of the roll. Then, while the winding end of the wrapping sheet is gripped, the roll is rotated to regulate the positional deviation of the wrapping sheet in the width direction, and the wrapping sheet is wrapped around the outer periphery of the roll. To be

Since the end of the packaging sheet is gripped and conveyed in this manner, the packaging sheet can be accurately positioned at the winding position as compared with the conventional structure in which the packaging sheet is conveyed by a suction belt or the like. You can Therefore, the packaging sheet can be accurately attached to the end of the roll-shaped material.

Further, when the roll-shaped material is rotated, the winding end of the packaging sheet is held. Thereby, when the packaging sheet is wrapped, the packaging sheet does not meander, and the packaging sheet can be wrapped around the outer periphery of the roll-shaped material with high accuracy.

Before releasing the holding of the winding end of the packaging sheet, the packaging sheet is held by the roller member, and in this state, the packaging sheet is wound around the end of the roll-shaped material. Therefore, the entire packaging sheet can be reliably wrapped around the outer periphery of the roll-shaped material.

Here, the packaging sheet has a sheet member and skirt members which are attached to both ends of the sheet member and cover the outer peripheral edge portions of both end surfaces of the roll-like material, and at the winding end of the sheet member. After the terminal fixing tape is attached, it is transported to the winding position. Therefore, for example, the entire packaging operation of the photosensitive material roll can be easily automated.
