Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll-shaped material skin-cutting device for axially incising a packing material on a peripheral surface of a roll-shaped material, and more particularly to a package formed by packing the roll-shaped material. The present invention relates to an apparatus for facilitating the removal of the packing material on the peripheral surface of the material whose end surfaces have been removed.
Here, the roll-like material is roll paper mainly used in a rotary printing machine, but other than that, plastic, paper,
It may be a roll-shaped material made of a material such as metal or wood, or a composite material of these materials. The packaging materials include various packaging materials such as kraft paper, paperboard, and plastic sheets.

[0002]

2. Description of the Related Art Generally, roll paper used in a rotary printing press is transported with its peripheral surface and end surface covered with packaging materials such as kraft paper, paperboard, and vinyl chloride resin sheet. Then, in order to apply this packed roll paper to a rotary printing machine, first remove the packing material on both end surfaces of the roll paper, then remove the packing material on the peripheral surface part, and then feed out the surface main paper from the roll paper. , Its tip has an appropriate shape (for example, V
(Paper shape) to form a paper edge, form an adhesive layer on the paper edge, rewind the paper edge on the roll paper, and temporarily fix it on the roll paper surface using the loosening prevention tabs. We are tailoring for.

Among these tailoring operations, an apparatus for removing the packing material on both end surfaces is disclosed in Japanese Patent Application Laid-Open No. 1-103293. Further, Japanese Patent Application Laid-Open No. 4-44940 discloses an apparatus that automates the process after removing the packing material on the end face portion. In the device described in the latter publication, in order to remove the packing material on the peripheral surface of the roll paper, the method shown in FIG.
As shown in FIG. 8, the packing material 2 on the peripheral surface of the roll paper 1 after removing the packing material on the end face and the surface main paper (one to several main papers on the front surface of the roll paper) 1a are set on the axis line of the roll paper 1. Direction, and then the wedge-shaped incision tool 3 is moved in the axial direction while being pressed against the outer peripheral surface of the roll paper 1 to incis the skin 4 including the packing material 2 and the surface layer main paper 1a over the entire width, and then the roll. The paper 1 was rotated to remove the incised epidermis 4.

[0004]

However, in the above-mentioned conventional device, before performing the incision by the wedge-shaped incision tool 3,
There is a problem that the skin 4 to be cut on the peripheral surface of the roll paper 1 needs to be displaced in the axial direction of the roll paper 1, which requires an operation and time. Therefore, the present applicant inserts a skin cutting tool directly at a position near the peripheral surface of the end surface of the roll paper so that the skin can be cut without shifting the skin 4 in the axial direction of the roll paper 1, and then cuts the skin. We have developed a device that moves the tool along the roll paper to cut the epidermis.

However, it has been found that the following problems occur when the skin cutting tool is directly pierced into the end surface of the roll paper. That is, even after the packaging material on the end surface of the roll paper has been cut and removed, some of the roll paper may have the same shape as in FIG.
As shown in FIG. 6, a part of the end surface packing material may remain as the remaining packing material 5 on the outer peripheral surface of the end surface, and if the uncut packing material 5 is present at the portion to be pierced with the skin cutting tool, Is the packaging material 5 where the tip of the epidermis cutting tool is left uncut.
There was a problem that a cutting error occurred because it could not be stabbed and pierced.

In such a case, the roll paper is rotated to pierce the skin cutting tool at a position where there is no uncut packing material, or the uncut packing material 5 is completely removed manually. Although it is sufficient to pierce the epidermis-cutting tool, it is inconvenient because manpower is required in both cases. It is also possible to detect unwrapped packaging material with a sensor and pierce the cover cutting tool while avoiding it, but it is extremely difficult to detect unwrapped packaging material, and there are many false detections by the sensor, resulting in loss of time. Occurs and is not a preferable method.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a skin even when there is a residual cut material on the end face of a roll-shaped material such as roll paper. It is an object of the present invention to provide a skin-cutting device for a roll-shaped object, which is capable of piercing a cutting tool without any hindrance and incising the packing material on the peripheral surface of the roll-shaped object.

[0008]

In order to achieve the above object, in the present invention, the end surface of a roll is pressed against the end surface radially inward of the insertion position for inserting the skin cutting tool, and then the end surface is pressed. The claw portion unit that moves outward in the direction and dispels the remaining packaging material remaining at the insertion position, and the claw portion so that the claw portion unit stops at a predetermined position with respect to the circumferential surface of the roll-shaped material. And a claw part unit, the claw part unit having two ends arranged with the claw part unit facing outward in the radial direction of the roll-shaped material, and the two claws. And an opening / closing means for opening and closing, the two claws having a shape that allows the tips to be inserted between the end surface of the roll-shaped material and the uncut packaging material remaining thereon, and the tips thereof. A little behind On the back, a structure having a pay-and-raised guide for causing pay uncut packaging material. Then, the claw unit moves radially outward while being pressed against the end surface of the roll-shaped object, and stops at the movement end position, after which the two claws open and pass between the two claws. An epidermis cutting tool is inserted into the end surface of the roll-shaped material, and the epidermis is incised.

In the skin cutting device having the above-mentioned structure, when the roll-shaped material is set at a predetermined position, the claw unit is pressed against the end surface of the roll-shaped material, and then the claw unit is radially moved along the end surface of the roll-shaped material. It moves outward and stops at the movement end position regulated by the positioning portion. During this movement, if there is uncut packaging material at that position, the claws of the claw unit will enter the inside of the uncut packaging material, and the unwrapped packaging material will be dispelled from the end surface of the roll-shaped material When the remaining packing material is long, the lifting guide provided on the claw lifts the long remaining packing material and holds it away from the end surface. After that, the claws of the claw unit open in two and cut the remaining packaging material so that there is no remaining packaging material between the two nails, or even if the remaining packaging material is not cut, And the scraping guide guides away the uncut packaging material so that there is no uncut packaging material between the two claws, then the skin cutting tool is inserted into the end face from between the open claws, Incision is made on the epidermis including the packaging material on the peripheral surface. Thus, when the outer skin cutting tool is inserted into the end surface of the roll-shaped material, the uncut unwrapping material does not interfere, and the outer skin is cut well.
