DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary blade wrapping structure for packaging a rotary blade for a brush cutter used for cutting grass, and more particularly, to a structure for rotating a single cardboard blank sheet. The present invention relates to a rotary blade packaging structure in which an insole plate is combined with a rotary blade packaging sheet comprising:

[0002]

2. Description of the Related Art Conventionally, a rotary blade having a plurality of saw-toothed blades formed on an outer peripheral portion of a metal disk is attached to a drive shaft.
BACKGROUND ART A brush cutter that brushes grass by rotating a rotary blade at high speed has been put to practical use. In general, the packaging before the rotary blade used for this type of brush cutter is displayed on the market is generally made of cardboard cut from 1 cardboard.
A rotary blade packaging sheet composed of two blank sheets is used. The packaging of the rotary blade using this packaging sheet is such that the rotary blade is placed on a substrate formed on the sheet, the left and right side plates are bent on the rotary blade, and the upper and lower cover plates are bent thereon and the two cover plates are overlapped and bonded. It is. In this case, a protective member having a crack formed in a transparent vinyl tube is previously attached to the cutting edge of the rotary blade to protect the cutting edge so that there is no danger from handling.

[0003]

However, when the above-described rotary blade is packaged by using a packaging sheet composed of one cardboard blank sheet, the sheet is folded into a rectangular thin box shape. Since the rotating blades are accommodated therein, prior to packaging, the rotating blades after packaging were folded into a thin box shape unless special measures were previously taken to fix the rotating blades to the substrate. Something moves in the space in the seat and lacks stability, which may cause a reduction in safety.

Therefore, the present invention has a simple structure in which a rotating blade packaging sheet that is folded into a thin box shape and wraps a rotating blade, and an insole plate is combined, so that the rotating blade is folded into a thin box shape. It is an object of the present invention to provide a packaging structure of a rotary blade that is more stable and has improved safety.

[0005]

In order to achieve the above object, a packaging structure for a rotary blade according to the present invention is formed on a single blank sheet made of cardboard, and has a substrate large enough to accommodate the rotary blade and a substrate. A rotary blade provided with left and right side plates that are bent on both sides of the substrate to cover the peripheral edge of the rotary blade, and upper and lower cover plates that are bent onto the substrate from both upper and lower sides of the substrate to cover the rotary blade and overlap and bond on the substrate In the packaging sheet, a pair of insole plates are arranged at opposed corner portions of the packaging sheet substrate,
At two locations on the outer edge portion of the insole plate, a sandwiching plate that is bent on the insole plate and sandwiches the peripheral edge of the rotary blade is provided continuously.

Here, the basic configuration of the rotary blade packaging sheet is the same as that of a known rotary blade packaging sheet.

[0007] According to the packaging structure of the rotary blade configured as described above, the periphery of the rotary blade is sandwiched between the pair of insole plates provided on the substrate surface of the packaging sheet, and the insole plate is used for packaging. Since the sheet is folded and packaged in a thin box shape, the rotation of the rotary blade in the packaging sheet folded in the thin box shape after the packaging is eliminated, and the stability is improved.

Although there is no particular limitation on the form of the insole plate, the insole plate has two sides forming a right angle, and a configuration is adopted in which these two sides are outer edges and a holding plate is connected to the two sides. ,
In order to dispose the insole board at the corner of the board, the insole board is positioned only by aligning two sides forming a right angle of the insole board, that is, the outer edge with the corner of the board. Therefore, the rotary blade can be clamped by the insole plate simply by bending the clamp plate to clamp the peripheral edge of the rotary blade, and there is no elaborate handling in using the insole plate, and the workability can be improved.

Further, since the holding plates provided with the two sides forming a right angle as outer edges are directed in the directions orthogonal to each other, the position of the holding plate provided on the insole plate is set to the position where the holding plate is directed toward the center of the rotary blade. When set, the peripheral portions of the rotary blades are balanced and held at equal intervals by the respective holding plates of the pair of insole plates. In addition, since the two holding plates provided on the insole plate can appropriately hold the peripheral edge of the rotating blade regardless of the size (difference in diameter) of the rotating blade, it can be used for packaging rotating blades of different sizes. The insole board can be used in common, and the insole board has high versatility. Further, here, the insole plate is formed in a right-angled isosceles triangle shape, and when the right-angled isosceles is set as the outer edge, all the cuts are straight cuts at the stage of manufacturing the insole plate, and the material can be saved, which is preferable. It is an embodiment.

Further, the holding plate of the insole plate is bent on the rotary blade to hold the rotary blade, and then has a thickness and elasticity by waving or the like to increase the pressing force of the rotary blade. Although it is also possible to adopt a configuration in which a folding plate that is folded outward is connected to the holding plate, and the outer edge of the folding plate is substantially matched with the outer edge of the insole plate in a state where the folding plate is folded on the holding plate. When the peripheral edge of the rotary blade is clamped by the clamping plate, the folded plate overlaps the clamping plate to increase the clamping force of the rotating blade, and the outer edge of the folded plate is three-dimensional with the outer edge of the insole plate. Since this comes into contact with the wrapping sheet surface that wraps it, that is, the left and right side plate surfaces and the upper and lower cover plate surfaces, more appropriate integration of the insole plate and the wrapping sheet that wraps the insole plate is achieved.
