Hereinafter, embodiments of the present invention will be described in detail.
The packaging material concerning this invention is a packaging material which covers so that the trunk | drum of cylindrical to-be-wrapped material may be wound, Comprising: The trunk | drum of roll paper (winding) which wound up paper products in roll shape especially As an example, a packaging material covering the above will be described.
In addition, a trunk | drum is a side part in cylindrical objects, such as a column. Moreover, the upper surface part and lower surface part which are the plane parts in a cylindrical shaped object are called edge parts.

  The packaging material 10 shown in FIGS. 1 and 2 is disposed on the outer side when the inner paper 11 as the first packaging sheet provided on the contact surface side with the winding 20 that is an object to be packaged and the winding 20 are wrapped. It is comprised by the exterior paper 12 as a 2nd packaging sheet provided so that it may be arrange | positioned, and the adhesive bond layer 13 which adhere | attaches these interior paper 11 and the exterior paper 12 at least.

The interior paper 11 is formed of moisture-proof paper that can reduce or prevent passage of moisture and moisture.
The length in the longitudinal direction of the interior paper 11 has a length that can be wound around at least one turn in the circumferential direction of the body portion 20 a of the winding 20. For example, the length in the longitudinal direction of the interior paper 11 is 1.1 times the circumferential length of the body 20a of the winding 20, and when the interior paper 11 is wound around the body 20a of the winding 20, The winding end portion 11b is wound so that the winding end portion 11b makes 1.1 turns.
The circumferential length is the length of the outer circumference of the winding 20 in a cross section taken along a plane perpendicular to the central axis when the paper product is rolled up. That is, it is the length of the circumference of a circle that is an upper surface portion or a lower surface portion of a cylindrical object such as a column.

The exterior paper 12 is formed of a sheet material for preventing the packaged item from being damaged or dirt from adhering to the packaged item. As the sheet material, a paper sheet such as kraft paper, a resin sheet such as a polyethylene sheet, a composite sheet obtained by bonding a paper sheet and a resin sheet, or the like can be used.
The length of the exterior paper 12 in the longitudinal direction has such a length that it can be wound around at least one turn in the circumferential direction of the body portion 20a of the winding 20, and at least two turns in the packaging material 10 in the present embodiment. It has a length that can be wound around. For example, the length in the longitudinal direction of the outer paper 12 is 2.5 times the circumference of the body 20a of the winding 20, and when the outer paper 12 is wound around the body 20a of the winding 20, The winding end portion 12b is wound so that the winding end portion 12b makes 2.5 turns.

The adhesive layer 13 is made of an adhesive for bonding the interior paper 11 and the exterior paper 12, or the exterior paper 12 and the exterior paper 12, on the inner surface side of the exterior paper 12 (contact surface side with the winding 20 and the interior paper 11). ) In a thin layer.
The adhesive layer 13 is provided from the winding end 12 b side of the exterior paper 12 toward the winding start end 12 a, and the interior of the exterior paper 12 overlapped with the exterior paper 12 from the winding end 12 b. The paper 11 is provided so as to cover a part between the end of winding 11b side of the paper 11.

Here, in the packaging material 10, when the exterior paper 12 and the interior paper 11 are laminated, the winding start end portion of the interior paper 11 so that the winding end portion 11 b of the interior paper 11 is superimposed on the exterior paper 12. 11a and the winding end part 11b are both arranged so as to be inside the longitudinal direction from the winding start end part 12a and the winding end part 12b of the exterior paper 12.
And the winding start edge part 11a of the interior paper 11 is arrange | positioned so that it may become a position of 0-200 mm inside the longitudinal direction from the winding start edge part 12a of the exterior paper 12, for example (in FIG. 1). , See arrow P).
In addition, the adhesive layer 13 extends, for example, from 100 to 200 mm from the winding end end 11 b of the interior paper 11 to the winding start end 11 a side with the interior paper 11 stacked on the exterior paper 12. The interior paper 11 and the exterior paper 12 are bonded together (see arrow Q in FIG. 1).

Then, as shown in FIG. 2, the wrapping material 10, while winding the winding start end portion 11 a of the interior paper 11 and the winding start end portion 12 a of the exterior paper 12 in the packaging material 10, The trunk portion 20a is covered so as to wind the trunk portion 20a.
In FIG. 2, a space is shown between the packaging material 10 and the winding 20 or between the wound packaging material 10, but FIG. 2 illustrates the winding of the packaging material 10. It is an explanatory diagram for showing the state in an easy-to-understand manner, so that it is shown as having a space for convenience. Actually, there is no space, and the packaging material 10 is attached to the body portion 20a of the winding 20 so as to be closely attached. Has been wounded.

Then, the adhesive layer 13 provided on the inner surface side of the exterior paper 12 comes into contact with the outer surface side of the exterior paper 12 (the surface side where the adhesive layer 13 in the exterior paper 12 is not provided), so that the position or The exterior paper 12 and the exterior paper 12 come to adhere within a range.
As described above, the winding end end portion 12b of the exterior paper 12 is adhered and fixed to the outer surface side of the exterior paper 12, so that the packaging material 10 covers the body portion 20a of the winding 20 and is packaged. .

Thus, the winding 20 can be packaged by winding the body portion 20a of the winding 20 with respect to the winding 20 of the packaging material 10. And while being able to prevent dirt from adhering to winding 20 (torso part 20a), moisture can be prevented from acting.
Note that the edge surface portion of the winding 20 may be wrapped by disposing an edge surface cover that covers the edge surface.

As described above, when removing the packaging material 10 wrapped so as to be wound around the body portion 20a of the winding 20 and collecting it, the automatic unpacking machine externally absorbs the surface side of the packaging material 10 by vacuum suction or the like. As a result, the front side of the packaging material 10 is floated and a gap is formed between the inside and the inside. Then, one front side of the packaging material 10 is cut with a cutter so as not to damage the winding 20 and removed so that the packaging material 10 is peeled off from the cut portion.
Note that one front side of the packaging material 10 is not only a single outer paper 12, but the wound outer paper 12 is bonded through an adhesive layer 13 so that substantially one sheet Also included are sheet members.

And, for example, in the wound packaging material 10 shown in FIG. 2, when the packaging material 10 is cut open at the wavy line portion indicated by the arrow C and removed from the winding 20, as shown in FIG. Although the exterior paper 12 is cut into three sheets, since they are bonded by the adhesive layer 13, they are not separated apart and can be maintained together with the interior paper 11.
Therefore, when the packaging material 10 is removed from the winding 20, the interior paper 11 and the exterior paper 12 can be collected as a single unit.
In addition, the winding start end 12a side portion of the outer paper 12 cut into three sheets is arranged on the front side in the drawing in FIG. 3B, and the outer paper 12 cut into three sheets is arranged. The winding end portion 12b side portion is bonded to the central portion of the cut exterior paper 12 so as to be arranged on the back side in the drawing in FIG.

Thus, when removing the packaging material 10 from the wound winding 20, the surface layer side of the packaging material 10 is cut and the packaging material 10 is peeled off from the cut portion. Since the exterior paper 12 can be removed integrally and recovered, the packaging material 10 can be said to be a packaging material that covers the winding 20 easily.
Further, the packaging material 10 having a configuration in which the interior paper 11 and the exterior paper 12 are bonded and overlapped at a part thereof is wound around the body portion 20a of the winding 20 from the winding start end side as described above, and the winding is finished. It can be said that the packaging method which covers the winding 20 so that the end side is bonded and fixed is a packaging method in which the packaged packaging material 10 can be easily removed.

  Moreover, in the packaging material, the position where the interior paper 11 is arranged with respect to the exterior paper 12 is arbitrary. You may make it arrange | position to the winding end edge part 12b side of the exterior paper 12. FIG.

In addition, it may be provided so as to extend from the winding end end 12b of the exterior paper 12 to the winding start end 12a and to extend to the winding end end 11b side of the interior paper 11 stacked on the exterior paper 12. .
Even with such a packaging material 102, packaging similar to that of the packaging material 10 can be performed.

Further, as shown in FIG. 6 , when the exterior paper 12 and the interior paper 11 are laminated, the winding start end of the interior paper 11 is arranged such that the winding end portion 11 b of the interior paper 11 is superimposed on the exterior paper 12. Both the part 11a and the winding end part 11b are wrapping materials arranged so as to be inside the longitudinal direction from the winding start end part 12a and the winding end part 12b of the exterior paper 12, and are overlapped with each other. The first adhesive layer 13a for bonding the inner paper 11 and the outer paper 12 on the end of winding end 11b side of the inner paper 11, and the second adhesive disposed on the end of winding end 12b side of the outer paper 12 The packaging material 200 which has the agent layer 13b may be sufficient.
Winding the packaging material 200 in such an arrangement that the interior paper 11 is the inner surface side and the outer paper 12 is the outer surface side so that the respective winding start ends (11a, 11b) are wound inside. By wrapping around the 20 body portions 20a, the winding end portion 12b of the exterior paper 12 is bonded and fixed by the second adhesive layer 13b, and packaging is performed.
Even with such a packaging material 200, packaging similar to that of the packaging material 10 can be performed.

Further, like the packaging material 201 shown in FIG. 7 , the first adhesive layer 13 a in the packaging material 200 is provided so as to extend from the winding end portion 11 b to the winding start end portion 11 a of the interior paper 11. Also good.

You may make it provide the layer 13a in the winding end end part 11b side of the interior paper 11 which overlapped with the exterior paper 12. FIG.
Even with such a packaging material 202, packaging similar to that of the packaging material 10 (packaging material 200) can be performed.

  In the embodiment described above, the cylindrical object to be packaged has been described by taking the winding 20 as an example. Can be used.

Further, as shown in FIG. 9 , the width direction of the packaging material 300 (inner paper 111, outer paper 121) is made longer than the height of the winding 20, so that the edge surface portion (upper surface portion, lower surface portion) of the winding 20. The packaging material 300 may cover and cover the edge surface portion of the winding 20 by folding the protruding packaging material portion with respect to the edge surface portion.

Further, the width of each adhesive layer may be adjusted according to the width of the interior paper, the height of the winding 20, etc., and it is desirable that the adhesive layer does not directly touch the winding 20. .
A plurality of adhesive layers may be provided as the adhesive layer along the longitudinal direction of the packaging material (inner paper, outer paper).

  Moreover, the location which cuts the packaged packaging material is also arbitrary.

  In addition, it is needless to say that other specific detailed structures can be appropriately changed.
