In the case, in principle, it refers to an acute angle.

Embodiment 1.
FIG. 1 is a cross-sectional view showing the packing device 1 according to the first embodiment. FIG. 1 corresponds to a view cut in a plane parallel to the vertical line. The packing device 1 shown in FIG. 1 is used for packing the object 90. The object 90 has a convex surface 91. The object 90 may be, for example, a compressor. The object 90 in the present embodiment includes a main body 92 having a cylindrical outer shape. The convex surface 91 is formed at one end of the main body 92. At least a part of the convex surface 91 in the present embodiment is a convex curved surface. In the present embodiment, the object 90 is arranged in a posture in which the convex surface 91 is located at the top, that is, in a posture in which the convex surface 91 faces upward. The central axis of the main body 92 is parallel to the vertical line. The convex surface 91 in the present embodiment has a shape along a rotating body obtained by rotating a plane curve with the central axis of the main body 92 as an axis of rotation. The convex surface 91 is inclined so that the position becomes lower as the distance from the central axis of the main body 92 increases.

The packing device 1 includes a tubular body 2 and a protruding portion 3. The tubular body central axis 4 is the central axis of the tubular body 2. The cylinder central axis 4 is parallel to the vertical line. The tubular body central axis 4 is coaxial with the central axis of the main body 92. The outer diameter of the cylinder 2 is smaller than the outer diameter of the main body 92. The tubular body 2 has a first end 5 and a second end 6. The first end 5 is on a virtual plane perpendicular to the central axis 4 of the cylinder, and forms an annular shape forming an opening. The first end 5 corresponds to the lower end of the tubular body 2. The second end 6 is on a virtual plane perpendicular to the central axis 4 of the cylinder, and forms an annular shape forming an opening. The second end 6 corresponds to the upper end of the tubular body 2.

The protruding portion 3 protrudes from the edge of the opening formed by the first end 5 toward the central axis 4 of the cylinder. The protrusion 3 is in contact with the convex surface 91. The first end 5 is fixed to the root portion of the protruding portion 3 with, for example, an adhesive. The protruding portion 3 has a plate shape. The lower surface, which is one surface of the protrusion 3, is in contact with the convex surface 91. The upper surface, which is the other surface of the protrusion 3, is fixed to the first end 5.

As a comparative example, consider a configuration in which the first end 5 is in direct contact with the convex surface 91. In this comparative example, it is as follows. The convex surface 91 of the portion in contact with the first end 5 is inclined. Therefore, the tubular body 2 may be displaced by sliding along the inclination of the convex surface 91. Since the contact area between the first end 5 and the convex surface 91 is small, the frictional force between the first end 5 and the convex surface 91 is small. Therefore, it is not possible to reliably prevent the tubular body 2 from slipping along the inclination of the convex surface 91 and shifting the position of the tubular body 2 during transportation or storage. If the position of the tubular body 2 is displaced, the object 90 cannot be reliably protected.

In contrast to this, in the present embodiment, since the contact area between the protruding portion 3 and the convex surface 91 can be increased by providing the protruding portion 3, the contact area between the protruding portion 3 and the convex surface 91 can be increased. The frictional force increases. Therefore, it is possible to reliably prevent the tubular body 2 from slipping along the inclination of the convex surface 91 during transportation or storage due to the frictional force. That is, the displacement of the tubular body 2 can be reliably prevented. Therefore, the object 90 can be reliably protected.

In the present embodiment, a plurality of protrusions 3 are provided for the first end 5 of one cylinder 2. As a result, the contact area between the protrusion 3 and the convex surface 91 can be made larger, and the frictional force between the protrusion 3 and the convex surface 91 can be made larger, so that the displacement of the tubular body 2 can be made more reliable. Can be prevented.

In the present embodiment, the protruding portion 3 can be deformed so as to be inclined with respect to the plane perpendicular to the central axis 4 of the cylinder by being pressed by the convex surface 91. As a result, the following effects can be obtained. By inclining the protruding portion 3, the protruding portion 3 becomes parallel to or close to parallel to the convex surface 91 in the contact region between the protruding portion 3 and the convex surface 91. As a result, the contact area between the protrusion 3 and the convex surface 91 can be made larger, and the frictional force between the protrusion 3 and the convex surface 91 becomes larger, so that the displacement of the tubular body 2 is more reliable. Can be prevented. The inclination angle of the protrusion 3 with respect to the plane perpendicular to the central axis 4 of the cylinder can be changed according to the inclination of the convex surface 91 at the position of the first end 5. Therefore, even when the object 90 having a different shape of the convex surface 91 is packed, the protruding portion 3 fits according to the shape of the convex surface 91. Therefore, even when the convex surface 91 is used for various objects 90 having different shapes, the above-mentioned effect can be obtained.

The packing device 1 of this embodiment is suitable for repeated use. The reason is as follows. As described above, the protruding portion 3 can be deformed so as to be inclined when pressed by the convex surface 91. After that, when the object 90 separates from the protruding portion 3, the inclination of the protruding portion 3 returns to the original position. Even if the protruding portion 3 is pressed against the convex surface 91, the tubular body 2 and the protruding portion 3 are not irreversibly deformed. Further, since no adhesive or the like is used at the contact position between the protruding portion 3 and the convex surface 91, the protruding portion 3 is not damaged when the object 90 and the protruding portion 3 are separated for unpacking. Therefore, the tubular body 2 and the protruding portion 3 can be reused when packing and unpacking are repeated. Therefore, the packing device 1 is suitable for being used as a so-called returnable packing device that is repeatedly transported between the shipping source and the shipping destination.

The packing device 1 of the present embodiment includes a first plate-shaped member 7 fixed to the first end 5. The first plate-shaped member 7 has a flat plate shape having a surface 8 perpendicular to the central axis 4 of the cylinder on the outside of the cylinder 2. The first end 5 is fixed to the surface 8. The first plate-shaped member 7 has a portion located inside the tubular body 2. The protruding portion 3 is formed by the first plate-shaped member 7 of the portion located inside the tubular body 2. That is, the portion of the first plate-shaped member 7 surrounded by the annular first end 5 forms the protruding portion 3.

The packing device 1 of the present embodiment further includes a second plate-shaped member 9. The second plate-shaped member 9 has a flat plate-like shape perpendicular to the central axis 4 of the cylinder. The tubular body 2 is inserted into the hole 10 formed in the second plate-shaped member 9. The hole 10 has a shape corresponding to the outer shape of the cross-sectional shape of the tubular body 2 cut in a plane perpendicular to the central axis 4 of the tubular body. That is, the inner circumference of the hole 10 and the outer circumference of the tubular body 2 are adjacent to or in contact with each other with almost no gap. The second plate-shaped member 9 overlaps the first plate-shaped member 7. The second plate-shaped member 9 is fixed to the surface 8 of the first plate-shaped member 7 with, for example, an adhesive.

Assuming that a force that moves the cylinder 2 in the lateral direction in FIG. 1 acts, the outer circumference of the cylinder 2 comes into contact with the inner circumference of the hole 10, and the movement of the cylinder 2 is prevented. As described above, in the present embodiment, by providing the second plate-shaped member 9, the misalignment of the tubular body 2 can be prevented more reliably. Further, even when an external force in the direction of the central axis 4 of the cylinder acts on the cylinder 2, it is possible to more reliably prevent buckling deformation of the cylinder 2 from occurring, so that the object 90 can be protected more reliably. Becomes possible.

In the illustrated example, two second plate-shaped members 9 are provided on top of each other, but even if one second plate-shaped member 9 is provided, the same effect as described above can be obtained. The second plate-shaped member 9 is provided as an auxiliary. That is, the packing device 1 in the present disclosure may not include the second plate-shaped member 9.

The tubular body 2 in the present embodiment has a cylindrical shape. As a modification, the tubular body 2 may have a polygonal tubular shape depending on the shape of the convex surface 91 or the cross-sectional shape of the main body 92.

The length of the tubular body 2 in the direction of the tubular body central axis 4 in the present embodiment is shorter than the outer diameter of the tubular body 2. Not limited to such a configuration, the length of the tubular body 2 in the direction of the central axis 4 of the tubular body may be equal to or larger than the outer diameter of the tubular body 2.

From the viewpoint of suppressing the influence on the environment when discarded, it is preferable that the tubular body 2, the protruding portion 3, the first plate-shaped member 7, and the second plate-shaped member 9 are made of paper. Further, the protruding portion 3, the first plate-shaped member 7, and the second plate-shaped member 9 may be made of corrugated cardboard.

In the following description, the structure formed by the tubular body 2, the protruding portion 3, the first plate-shaped member 7, and the second plate-shaped member 9 will be referred to as the first structure 11. FIG. 2 is a plan view of the first structure 11 included in the packing device 1 according to the first embodiment. FIG. 2 corresponds to a view viewed from a direction parallel to the central axis 4 of the cylinder. FIG. 3 is a side view of the first structure 11 included in the packing device 1 according to the first embodiment. FIG. 3 corresponds to a view viewed from a direction perpendicular to the central axis 4 of the cylinder. In FIG. 3, a part is taken as a cross-sectional view.

As shown in FIGS. 2 and 3, in the present embodiment, a plurality of tubular bodies 2 having the same structure are attached to one first plate-shaped member 7. The plurality of tubular bodies 2 are connected to each other via the first plate-shaped member 7. In the present embodiment, since the plurality of cylinders 2 are connected to each other, the displacement of the cylinders 2 can be prevented more reliably. In this embodiment, a plurality of cylinders 2 are arranged in a matrix. In the illustrated example, 16 cylinders 2 are arranged in 4 rows × 4 columns.

As shown in FIG. 2, in the present embodiment, each of the tubular bodies 2 is provided with a plurality of protruding portions 3 arranged along the circumferential direction of the tubular body 2. As a result, the frictional force between the protrusion 3 and the object 90 acts uniformly in the circumferential direction of the tubular body 2. Therefore, the displacement of the tubular body 2 can be prevented more reliably.

In particular, in the present embodiment, for each of the tubular bodies 2, a plurality of protruding portions 3 are lined up over the entire circumference of the tubular body 2. As a result, the frictional force between the protrusion 3 and the object 90 acts more uniformly in the circumferential direction of the tubular body 2. Therefore, the misalignment of the tubular body 2 can be prevented more reliably.

As shown in FIG. 2, in the present embodiment, a plurality of cut lines extending radially are formed on the first plate-shaped member 7 inside the tubular body 2. A plurality of protrusions 3 are formed by the plurality of radial cut lines. Each of the plurality of projecting portions 3 is adjacent to each other via a cut line along the radial direction of the tubular body 2. Each of the plurality of protrusions 3 has a fan shape by being partitioned by two notch lines. With such a configuration, in the present embodiment, since no gap is formed between the adjacent protrusions 3, it is more advantageous in increasing the contact area between the protrusions 3 and the object 90. The cut line between the protrusions 3 reaches the inner wall of the cylinder 2. In the illustrated example, each protrusion 3 has a fan shape with a central angle of 30 degrees. Then, 12 protrusions 3 are arranged along the circumferential direction for each cylinder 2.

FIG. 4 is a perspective view showing a state when the object 90 is packed by using the packing device 1 according to the first embodiment. FIG. 5 is a perspective view showing a state in which packing is completed from the state of FIG. As shown in FIG. 4, in the present embodiment, the objects 90 are packed in a state of being stacked in two stages on one pallet 12. In the illustrated example, a total of 32 objects 90, including the 16 objects 90 in the first stage and the 16 objects 90 in the second stage, are stacked on one pallet 12. The pallet 12 is made of resin, for example.

The procedure for packing the object 90 with the packing device 1 will be described below. First, the veneer plate 13 is laid on the upper surface of the pallet 12. The second structure 14 is placed on the veneer plate 13. The second structure 14 is, for example, a paper plate-shaped member. A recess into which the lower portion of the object 90 fits is formed on the upper surface of the second structure 14. For example, the foot portion attached to the lower part of the main body 92 of the object 90 is inserted into the recess, so that the object 90 is arranged at an appropriate position. In the illustrated example, 16 objects 90 in the first stage are placed on the second structure 14.

Next, the first structure 11 is put on the 16 objects 90 in the first stage. The veneer plate 13 and the second structure 14 are placed on the first structure 11. 16 objects 90 in the second stage are placed on the second structure 14. The first structure 11 is placed on the 16 objects 90. The protrusions 3 of the tubular body 2 included in the first structure 11 come into contact with the convex surfaces 91 of the plurality of objects 90 in the first and second stages as shown in FIG.

In this way, in the present embodiment, the tubular body 2 and the protruding portion 3 of the first structure 11 arranged on the lower object 90 support the load of the upper object 90. In the present embodiment, since the contact area between the protrusion 3 and the object 90 is large, it is possible to reliably prevent the surface of the lower object 90 from being marked by the load of the upper object 90.

Next, the side sleeve 15 is placed on the pallet 12 so as to cover the periphery of the object 90, the first structure 11, the second structure 14, and the like on the pallet 12 from the outside. The side sleeve 15 may be made of paper, for example. Then, the lid 16 is placed on the first structure 11 at the uppermost portion. The lid 16 may be made of resin, for example. Finally, as shown in FIG. 5, the pallet 12 and the lid 16 are fastened with the band 17. The band 17 may be, for example, a polypropylene band.

A plurality of recesses 18 are formed on the upper surface of the lid 16. The recess 18 is formed at a position corresponding to a plurality of legs 19 provided on the bottom surface of the pallet 12. The completed packing devices 1 shown in FIG. 5 can be stacked in a plurality of stages. At that time, the legs 19 of the pallet 12 of the upper packing device 1 enter the recess 18 of the lid 16 of the lower packing device 1, so that the relative positions of the two in the horizontal direction can be reliably positioned.

According to the packing device 1 of the present embodiment described above, the following effects can be obtained. Even if it receives horizontal vibration or impact during distribution, it is possible to reliably prevent the first structure 11 from being displaced with respect to the object 90. As a result, it is possible to reliably prevent the tubular body 2 supporting the stacked load from coming off the object 90 during storage in a warehouse or transportation by truck or the like. Therefore, it is possible to reliably protect the object 90 without causing an unbalanced load, and it is possible to reliably prevent the occurrence of quality defects during distribution.

Embodiment 2.
Next, the second embodiment will be described with reference to FIG. 6, but the differences from the first embodiment will be mainly described, and the same or corresponding parts will be simplified or omitted. FIG. 6 is a view of the cylinder body 2 and the protruding portion 3 included in the packing device according to the second embodiment as viewed from a direction parallel to the cylinder body central axis 4.

As shown in FIG. 6, in the present embodiment, the tip of the protrusion 3 does not reach the central axis 4 of the cylinder. A circular hole 20 surrounded by the tips of the plurality of protrusions 3 is formed. The individual protrusions 3 in the present embodiment have a fan-shaped shape lacking the apex portion. In the illustrated example, eight protrusions 3 having a fan-shaped shape with a central angle of 45 degrees are provided for one cylinder 2. In the case of the present embodiment, the same effect as that of the first embodiment can be obtained.

Embodiment 3.
Next, the third embodiment will be described with reference to FIG. 7, but the differences from the first embodiment will be mainly described, and the same or corresponding parts will be simplified or omitted. FIG. 7 is a plan view of the first structure 11A included in the packing device 1A according to the third embodiment.

As shown in FIG. 7, the first hole 21 and the second hole 22 are formed in the first structure 11A in the present embodiment. The first hole 21 and the second hole 22 are formed in the first plate-shaped member 7 and the second plate-shaped member 9. A plurality of sets of first hole 21 and second hole 22 are provided for each cylinder 2 so that the positional relationship with the cylinder 2 is the same. In FIG. 7, the first hole 21 has a portion located outside the tubular body 2 and a portion located inside the tubular body 2. The first hole 21 of the portion located inside the tubular body 2 occupies a fan-shaped region having a central angle of 60 degrees. The second hole 22 is on the outside of the tubular body 2 and is in a position not in contact with the tubular body 2.

The first hole 21 and the second hole 22 correspond to relief portions for preventing interference with the protruding portion protruding from the object 90. For example, when the object 90 is a compressor, a pipe serving as an inlet or an outlet for the refrigerant protrudes from the object 90. In the present embodiment, by forming the first hole 21 and the second hole 22 at the position of the protruding portion, it is possible to prevent the first structure 11A from coming into contact with the protruding portion.

In the present embodiment, the number of protrusions 3 provided for one tubular body 2 is 10 which is 2 less than that of the 1st embodiment. This is because the protrusion 3 at the position of the first hole 21 formed inside the tubular body 2 is lacking. In the present embodiment, ten protrusions 3 having a fan shape with a central angle of 30 degrees are arranged along the circumferential direction of the tubular body 2. That is, a plurality of protrusions 3 are lined up over a range in which the central angle with respect to the cylinder central axis 4 is 300 degrees. In the present embodiment, the frictional force between the protrusion 3 and the object 90 is the cylinder as in the case where the plurality of protrusions 3 are lined up over the entire circumference of the cylinder 2 as in the first embodiment. It acts more uniformly with respect to the circumferential direction of the body 2. Therefore, the displacement of the tubular body 2 can be prevented more reliably. If a plurality of protruding portions 3 are lined up over a range in which the central angle with respect to the cylinder central axis 4 is 270 degrees or more, an effect similar to the above can be obtained.

It should be noted that, of the plurality of embodiments described above, two or more that can be combined may be combined and implemented.
