[0002] This application claims priority to Japanese Patent Application No. 2024-193111, filed on November 1, 2024, the contents of which are incorporated herein by reference. Technical Field

[0003] This invention relates to bundles. Background Technology

[0004] Japanese Patent Application Publication No. 2010-127120 discloses an example of a dry vacuum pump unit. This dry vacuum pump unit has a rectangular box-shaped outer casing, with an intake pipe provided on the upper surface of the outer casing and an exhaust pipe provided on the side of the outer casing.

[0005] However, the aforementioned dry vacuum pump units are typically housed in bundles within wooden frames for storage and on-site handling. Since dry vacuum pump units come in various sizes depending on specifications, bundle sizes have historically been designed to match these dimensions. Consequently, the inventory of over 200 different bundle types has become a significant burden in terms of resources, cost, and operational management.

[0006] Regarding the bundling body, prepare a bundling box that matches the size of the item being bundled, and cover the item to prevent it from being broken or damaged due to vibration or impact during handling. However, the item being bundled is not hexahedral in shape; even if it is, if there are protrusions or other irregularities around it, a gap will inevitably be created between the bundling box and the item. In this case, it is necessary to fill the gap with cushioning material and study how to fill the gap to prevent the item being bundled from vibrating or moving within the bundling box.

[0007] Furthermore, the aforementioned problems are not limited to dry vacuum pump units, but also include technical issues related to other types of pumps, compressors, turbines, blowers, and other fluid machinery, as well as bundled objects of various sizes. Summary of the Invention

[0014] In the fifth embodiment of the present invention, according to the first embodiment of the bundle, a pair of the first angle pieces are assembled in a grid pattern into a plurality of the box-fixing components.

[0015] In the sixth embodiment of the present invention, according to the fourth embodiment of the bundling body, casters are provided on the bottom surface of the bundled object, and a ramp component formed of the corrugated cardboard is housed in the bundling box and is used when the bundled object is moved out.

[0034] Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings. Furthermore, in the following description, a pump (specifically a dry vacuum pump unit) is exemplified as the object to be bundled, but the object to be bundled is not necessarily limited to this pump.

[0035] (First Implementation)

[0036] Figure 1 This is a perspective view of the bundle 1 according to the first embodiment. Figure 2 This is an exploded perspective view of the bundle 1 according to the first embodiment.

[0037] As shown in these figures, the bundle body 1 includes: a bundle box 2 for containing the bundled object 100, a tray 3 for supporting the bundle box 2, and a strap 4 for fixing the tray 3 and the bundle box 2.

[0038] Furthermore, in the following description, an XYZ orthogonal coordinate system is established, and the positional relationships of each component are explained with reference to this XYZ orthogonal coordinate system. The X-axis direction is the direction of the short side of the rectangular box-shaped bundle 1 when viewed from above. The Y-axis direction is the direction of the long side of the rectangular box-shaped bundle 1 when viewed from above. The Z-axis direction is the height direction of the rectangular box-shaped bundle 1 when viewed from above.

[0039] like Figure 2 As shown, the bundled object 100 in this embodiment is rectangular box-shaped, with multiple protrusions 101 on the upper surface and multiple casters 102 on the bottom surface. Examples of the protrusions 101 include eye bolts used when lifting the bundled object 100 (pump), but not limited to eye bolts.

[0040] In this embodiment, both the bundle box 2 and the pallet 3 are made of corrugated cardboard. Furthermore, when the bundle body 1 is overlapped, the bottom wall 11 and the cover 12 can also be made of corrugated cardboard. The pallet 3 can be a wooden pallet, a resin pallet, or a metal pallet, but a paper pallet is preferred from the viewpoint of saving resources, reducing costs, and facilitating operation and management, thus making it entirely paper-based. However, when the pallet 3 is made of paper, it is not limited to corrugated cardboard.

[0041] The 4-band is typically made of resin, but it can also be a rope, thread, chain, etc. Furthermore, as the corrugated paper, it is preferable to use corrugated paper with a higher core strength than that used in ordinary corrugated paper to improve compressive strength (so-called reinforced corrugated paper). Examples of such reinforced corrugated paper include cases where a paper with a significantly higher ring crush value than a typical core (around 120 scp) is used, and cases where a liner with a higher basis weight than a typical liner (around 200 g basis weight) is used (around 400 g basis weight).

[0042] The pallet 3 includes a top plate 3a, a bottom plate 3b, and a plurality of supports 3c disposed between the top plate 3a and the bottom plate 3b. The top plate 3a and the bottom plate 3b are rectangular plates when viewed from above. The supports 3c are disposed at least at the four corners of the top plate 3a and the bottom plate 3b, and at the middle of the long side of the top plate 3a and the bottom plate 3b, respectively. The upper end of the supports 3c is fixed to the top plate 3a by adhesive or the like, and the lower end of the supports 3c is fixed to the bottom plate 3b by adhesive or the like.

[0043] The top plate 3a and bottom plate 3b are formed, for example, by overlapping one or more rectangular corrugated sheets of paper and then bonding them together. The support column 3c is formed, for example, by housing a block-shaped structure made by overlapping multiple sheets of corrugated paper within a box-shaped corrugated sheet. Since the tray 3 part is close to the ground, it may get wet due to the location, so waterproof corrugated paper can be used. In addition, as long as water resistance can be ensured, the support column 3c can also be formed by overlapping multiple sheets of corrugated paper, or other corrugated paper can be glued in a cover shape to a corrugated section that looks like a step to prevent water from entering.

[0044] In the tray 3, a space 3d extending through the X-axis direction is formed between the support columns 3c.

[0045] The straps 4 that constrain the bundle 2 and pallet 3 pass through the space 3d, and when the bundle 1 is being moved, the lifting top of the forklift is inserted into the space 3d.

[0046] The bundle box 2 has a side wall 10, a bottom wall 11, and a lid 12. For example... Figure 2 As shown, the sidewall portion 10 is rectangular in shape when viewed from above, forming a square frame that surrounds the bundled object 100. Furthermore, the sidewall portion 10 can also be separated into multiple parts (for example, two L-shaped parts when viewed from above) depending on the size of the bundled object 100.

[0047] The bottom wall portion 11 is formed into a planar rectangular box shape with an opening at the top. The support platform 30 supporting the bundled object 100 is fixed to the inside of the bottom wall portion 11 by adhesive or the like. The support platform 30 is also formed of corrugated cardboard. The support platform 30 includes: a first truss 31, and a second truss 32 combined with the first truss 31.

[0048] A pair of first trusses 31 are spaced apart in the Y-axis direction and extend parallel to the X-axis direction. The first trusses 31 are, for example, blocks of corrugated paper overlapping each other. To support heavy objects, these blocks can be positioned with the overlapping surfaces of the corrugated paper perpendicular to the ground. A pair of first trusses 31 are positioned inside the casters 102 located on the bottom surface of the bundled object 100 in the Y-axis direction, and support the bottom surface of the bundled object 100 while the casters 102 are lifted from the bottom wall portion 11. Thus, the first trusses 31 can buffer vibrations from below, such as from the ground, relative to the bundled object 100, preventing direct transmission of vibrations to the bundled object 100. Furthermore, the first trusses 31 prevent the load of the bundled object 100 from concentrating on a portion of the bottom wall portion 11, thereby maintaining the strength of the bottom wall portion 11.

[0049] A pair of second trusses 32 are spaced apart in the X-axis direction and extend parallel to the Y-axis direction. The second trusses 32 are formed from the first angle members 21, which will be described later. The pair of second trusses 32 are joined to the upper surface of the pair of first trusses 31 in a crisscross pattern by adhesive or the like. The pair of second trusses 32 suppress vibrations in the X-axis direction during transport by abutting against the two sides of the bundled object 100 in the X-axis direction.

[0050] The cover 12 is formed as a rectangular, topped box with an opening at the bottom when viewed from above. For example... Figure 1 As shown, the cover portion 12 blocks the upper opening of the side wall portion 10 and surrounds the upper opening of the side wall portion 10 from all sides. In addition, the bottom wall portion 11 also blocks the lower opening of the side wall portion 10 and surrounds the lower opening of the side wall portion 10 from all sides.

[0051] Figure 3 This is a diagram showing the internal structure of the bundle 1 of the first embodiment as viewed from the X-axis direction. Figure 4 This is a diagram showing the internal structure of the bundle 1 of the first embodiment as viewed from the Z-axis direction.

[0052] As shown in these figures, an internal fixing component 20 for fixing the bundled object 100 is provided inside the bundling box 2. In addition, the symbol 103 in the figure is a suction tube provided on the upper surface of the bundled object 100 (dry vacuum pump unit).

[0053] like Figure 4 As shown, the two ends of the internal fixing component 20 are fixed to the opposite surfaces of the side wall portion 10. In this embodiment, the side wall portion 10 has a pair of first side wall portions 10a facing each other in the long side direction (Y-axis direction) and a pair of second side wall portions 10b facing each other in the short side direction (X-axis direction). The internal fixing component 20 is fixed to the opposite surfaces of the pair of second side wall portions 10b by fixing components 5 such as self-tapping screws.

[0054] Figure 5This is a perspective view of the box fixing component 20 of the first embodiment. Figure 6 This is an exploded perspective view of the box fixing component 20 of the first embodiment.

[0055] like Figure 5 As shown, the internal fixing component 20 includes: a first corner piece 21, which is formed by overlapping multiple paper components and bending them into an L-shape; and a pair of second corner pieces 22, which are also formed by overlapping multiple paper components and bending them into an L-shape, with the two ends of the first corner piece 21 fixed to the opposite surfaces of the side wall portion 10. Furthermore, the paper components forming the first and second corner pieces can be ordinary corrugated paper, corrugated paper, or other paper L-shaped corner pieces. Additionally, as long as the strength requirement is met, overlapping multiple sheets of the paper components is not necessary. Moreover, the paper components, for example, refer to components formed by laminating 100% pulp paperboard, bonding it, and stamping it.

[0056] like Figure 6 As shown, the first angle member 21 is L-shaped when viewed from the X-axis direction, and extends in the X-axis direction with the same shape. The first angle member 21 has a horizontal portion 21a and a vertical portion 21b that bends relative to the horizontal portion 21a. Figure 3 as well as Figure 4 As shown, the horizontal portion 21a is the part that abuts against the upper surface of the bundled object 100. Additionally, as... Figure 3 as well as Figure 4 As shown, the vertical portion 21b is the portion that abuts against the side of the protrusion 101.

[0057] like Figure 6 As shown, the second angle member 22 is L-shaped when viewed from the Z-axis direction, and extends in the Z-axis direction with the same shape. The second angle member 22 includes: a first angle member opposing portion 22a, and a sidewall opposing portion 22b that bends relative to the first angle member 21. The first angle member opposing portion 22a is opposite to the vertical portion 21b of the first angle member 21 and is fixed by a fixing member 6 such as a staple (see reference). Figure 5 Furthermore, the Z-axis dimension of the opposite portion 22a of the first angle member is the same as the Z-axis dimension of the vertical portion 21b.

[0058] The opposing sidewall portion 22b is disposed at the end of the horizontal portion 21a in the X-axis direction. The opposing sidewall portion 22b is opposite to the sidewall portion 10 (second sidewall portion 10b) of the bundle box 2. The dimension of the opposing sidewall portion 22b in the Y-axis direction is the same as that of the horizontal portion 21a in the Y-axis direction. Furthermore, the opposing sidewall portion 22b is supported on the horizontal portion 21a of the first angle member 21. Thus, even when a bending load such as that near the horizontal portion 21a is applied to the vertical portion 21b of the first angle member 21, the second angle member 22 can still serve as a support for the vertical portion 21b. That is, the load applied to the opposing sidewall portion 22b can be supported by the thickness of both the vertical portion 21b and the opposing first angle member 22a. Furthermore, the first angle member 21 and the second angle member 22 are assembled as described above, but they can also be integrally formed by pulp molding or other methods, provided that the strength is sufficient.

[0059] The aforementioned internal fixing component 20 is located inside the packing box 2, such as... Figure 3 as well as Figure 4 As shown, the configuration is as described. In this embodiment, the first protrusion 101a and the second protrusion 101b are separately disposed on the upper surface of the bundled object 100 in the Y-axis direction. The box-in-box fixing member 20 includes: a first box-in-box fixing member 20a that abuts against the upper surface of the bundled object 100 and the first protrusion 101a, and a second box-in-box fixing member 20b that abuts against the upper surface of the bundled object 100 and the second protrusion 101b.

[0060] The first box-mounted fixing component 20a and the second box-mounted fixing component 20b suppress vibration in the Z-axis direction when the bundled object 100 is transported by abutting against the upper surface of the bundled object 100.

[0061] Furthermore, the first internal fixing member 20a abuts against the side of the first protrusion 101a on the +Y side, relative to the first protrusion 101a disposed on the -Y side. Moreover, the second internal fixing member 20b abuts against the side of the second protrusion 101b disposed on the +Y side, not the side on the +Y side, but the side on the -Y side, opposite to it. Thus, the first internal fixing member 20a and the second internal fixing member 20b suppress vibration in the Y-axis direction when transporting the bundled object 100.

[0062] Thus, the bundling body 1 of this embodiment described above includes: a bundling box 2, which is formed of corrugated cardboard and has four square sidewall portions 10 surrounding the bundled object 100; and an internal fixing member 20, the two ends of which are fixed to the opposite surfaces of the sidewall portions 10. The internal fixing member 20 includes: a first corner piece 21, which is formed by overlapping multiple paper components and bending them into an L-shape; and a pair of second corner pieces 22, which are formed by overlapping multiple paper components and bending them into an L-shape, and the two ends of the first corner piece 21 are fixed to the opposite surfaces of the sidewall portions 10.

[0063] According to this structure, even if the size of the bundling box 2 does not match the bundled object 100, the bundled object 100 can be fixed at any position inside the bundling box 2 by means of the internal fixing component 20. As a result, the sizes of the bundling box 2 can be reduced from more than 200 types to just a few types.

[0064] Furthermore, as described in Patent Document 1, the bundled object 100 (pump) is formed by bundling the pump, motor, and connecting and control mechanisms together, and its center of gravity may not be located at the center of the bundled object 100. Therefore, by fixing the bundled object 100 at any position within the bundling box 2, its center of gravity can be placed in the center of the bundled body 1. Thus, when the forklift moves, the bundled body 1 can be moved without the forklift driver having to pay attention to each bundle to prevent it from tilting. In addition, the use of corrugated cardboard for the internal fixing parts 20 allows it to withstand external forces during handling, and it is easy to manufacture and dispose of on-site.

[0065] Furthermore, by using the lower second truss 32 to suppress the movement of the bundled object 100, which is a heavy object, in the X-axis direction, and by using the upper first angle member 21 to suppress the movement of the bundled object 100 in the Y-axis direction, it is not necessary to fill the gaps with cushioning material in order to prevent the bundled object 100 in the bundled body 1 from vibrating or moving.

[0066] Furthermore, regarding the first angle bar 21 and the second angle bar 22, identical angle bars can be cut and joined together, or other angle bars can be used within the range of specifications described above. For example, the thickness and number of overlapping angle bars can also be different. When the angle bars are cut and joined together, since the bundle box 2 is made of reinforced corrugated cardboard, unlike wood, the internal fixing component 20 can be installed even if the dimension in the Y-axis direction is slightly larger. Moreover, even with the smaller first angle bar 21, the calculated dimension in the Y-axis direction can be changed simply by altering the installation method of the second angle bar 22, thus enabling its use.

[0067] Furthermore, in this embodiment, a protrusion 101 is provided on the upper surface of the bundled object 100, and the internal fixing member 20 abuts against the upper surface of the bundled object 100 and the side of the protrusion 101. According to this structure, the vibration during handling of the bundled object 100 can be suppressed by using the protrusion 101 provided on the upper surface of the bundled object 100.

[0068] In this embodiment, a first protrusion 101a and a second protrusion 101b are provided on the upper surface of the bundled object 100. The box-mounted fixing component 20 includes: a first box-mounted fixing component 20a, which abuts against the upper surface of the bundled object 100 and the +Y side (first side) of the first protrusion 101a; and a second box-mounted fixing component 20b, which abuts against the upper surface of the bundled object 100 and the -Y side (second side) of the second protrusion 101b facing opposite to the first side. According to this structure, the vibration of the bundled object 100 in two directions (Y-axis direction and Z-axis direction) can be suppressed by the two box-mounted fixing components 20. Alternatively, the first box fixing component 20a and the second box fixing component 20b may be arranged to clamp the first protrusion 101a and the second protrusion 101b from the outside of the Y-axis direction, rather than from the inside of the Y-axis direction.

[0069] Furthermore, in this embodiment, casters 102 are provided on the bottom surface of the bundled object 100, and the bundle box 2 has a support platform 30 formed of corrugated cardboard, which supports the bottom surface of the bundled object 100 with the protrusions raised. With this structure, the swaying of the bundled object 100 on the bottom wall 11 of the bundle box 2 due to the casters 102 can be suppressed. Additionally, in this case, the first truss 31 can buffer vibrations from below, such as the ground, preventing the vibrations from being directly transmitted to the bundled object 100.

[0070] Furthermore, this embodiment includes: a pallet 3 that supports the bundled box 2; and a strap 4 that secures the pallet 3 and the bundled box 2. With this structure, the bundled box 2 and the pallet 3 can be easily transported together using a forklift or similar equipment.

[0071] Furthermore, in this embodiment, the object to be bundled 100 is a pump. This structure facilitates the bundling and handling of pumps of various sizes.

[0072] Thus, according to the above-described embodiment, a bundle 1 that is resource-saving, low-cost, and easy to operate and manage can be provided.

[0073] (Second Implementation)

[0074] Next, a second embodiment of the present invention will be described. In the following description, structures that are the same as or equivalent to those in the embodiments described above will be marked with the same reference numerals, and their descriptions will be simplified or omitted.

[0075] Figure 7 This is a diagram showing the internal structure of the bundle 1 in the second embodiment as viewed from the X-axis direction. Figure 8 This is a diagram showing the internal structure of the bundle 1 in the second embodiment as viewed from the Z-axis direction.

[0076] As shown in these figures, in the second embodiment, a pair of internal fixing components 20 are provided on both sides of the protrusion 101.

[0077] The second embodiment of the bundling body 1 accommodates a bundling object 100 that is larger than that of the first embodiment. Therefore, a third box-in-box fixing component 20c and a fourth box-in-box fixing component 20d are also provided inside the bundling box 2.

[0078] The third box-in-place fixing component 20c abuts against the upper surface of the bundled object 100 and the side of the first protrusion 101a on the -Y side. That is, the first protrusion 101a is sandwiched between the first box-in-place fixing component 20a and the third box-in-place fixing component 20c in the Y-axis direction.

[0079] The fourth box-in-place fixing component 20d abuts against the upper surface of the bundled object 100 and the side of the second protrusion 101b on the +Y side. That is, the second protrusion 101b is sandwiched between the second box-in-place fixing component 20b and the fourth box-in-place fixing component 20d in the Y-axis direction.

[0080] Furthermore, in the second embodiment, to support the large bundled object 100, one more first truss 31 is added to the support platform 30, resulting in a total of three trusses. Additionally, in the second embodiment, a reinforcing part 3e is provided to prevent the top plate 3a of the tray 3 from deforming due to the weight of the bundled object 100. The reinforcing part 3e is similar to the first truss 31 described above, and is, for example, a block formed by overlapping multiple corrugated sheets, which can be oriented with the overlapping surfaces of the corrugated sheets perpendicular to the ground.

[0081] Thus, in the second embodiment described above, a pair of internal fixing members 20 are provided on both sides of the protrusion 101. According to this structure, even if the object 100 being bundled is large, vibrations during transport can be sufficiently suppressed.

[0082] (Third Implementation)

[0083] Next, a third embodiment of the present invention will be described. In the following description, structures that are the same as or equivalent to those in the embodiments described above will be marked with the same reference numerals, and their descriptions will be simplified or omitted.

[0084] Figure 9 This is a diagram showing the internal structure of the bundle 1 in the third embodiment as viewed from the X-axis direction. Figure 10 This is a diagram showing the internal structure of the bundle 1 in the third embodiment, viewed from the Z-axis direction.

[0085] As shown in these figures, in the third embodiment, a ramp component 40, which is formed of corrugated cardboard, is housed in the packing box 2 and is used when the bundled object 100 is moved out.

[0086] The ramp component 40 has a right-angled triangular shape when viewed from the X-axis direction. The ramp component 40 is positioned on the same mounting surface as the tray 3 (in...). Figure 9 The height of the pallet 3 is the same as that of the tray 3 (represented by a double-dotted line). Furthermore, by unfolding a portion 11a of the bottom wall 11, a continuous ramp surface with the ramp member 40 can be formed. This ramp member 40 is, for example, mounted on the box fixing member 20 and housed within the bundling box 2. Since the direction of movement of the bundled object 100 based on the casters 102 is the Y-axis direction, if the ramp member 40 is moved out in the Y-axis direction while remaining in its bundled state, the height of the ramp member 40 is the same as that of the tray 3, thus forming a continuous ramp surface. Therefore, the bundling, conveying, storage, and unloading of the bundled object 100 can be performed smoothly.

[0087] Furthermore, in the third embodiment, since the bundled object 100 is a lightweight item, a support platform 30 is not provided to facilitate the removal of the bundled object 100 based on the casters 102. Instead, as a unit to suppress vibration in the X-axis direction when handling the bundled object 100, a pair of first angle brackets 21 are assembled in a crisscross pattern into the first box-mounted fixing member 20a and the second box-mounted fixing member 20b.

[0088] like Figure 10 As shown, the horizontal portions 21a of a pair of first angle brackets 21 are fixed to the lower surfaces of the first box-in-the-box fixing member 20a and the second box-in-the-box fixing member 20b, and the vertical portions 21b of the pair of first angle brackets 21 abut against the two sides of the bundled object 100 in the X-axis direction. Therefore, even without the support platform 30, vibration of the bundled object 100 during transport in the X-axis direction can be suppressed. Furthermore, although not shown, the pair of first angle brackets 21 are fixed to the first box-in-the-box fixing member 20a and the second box-in-the-box fixing member 20b by fastening components such as self-tapping screws or staples.

[0089] Figure 11 This is a perspective view of the ramp component 40 according to the third embodiment.

[0090] like Figure 11As shown, the ramp component 40 includes a ramp portion 41 and a base portion 42 that supports the ramp portion 41.

[0091] Figure 12 This is an exploded perspective view of the base portion 42 of the third embodiment. Figure 13 This is a perspective view showing the first step of assembling the ramp component 40 according to the third embodiment. Figure 14 This is a perspective view showing the second step of assembling the ramp component 40 according to the third embodiment.

[0092] like Figure 12 As shown, the base portion 42 includes a first groove-shaped member 43 and a second groove-shaped member 44. The first groove-shaped member 43 has a flat bottom 43a and a pair of side portions 43b that are right-angled triangular shapes when viewed from the side when the bottom 43a is erected. A plurality of slits 43c are formed in the pair of side portions 43b. In addition, an insertion portion 43d extending rearward toward the pair of side portions 43b is formed in the bottom 43a. The first groove-shaped member 43 is fixed in a three-part manner with the side portions 43b facing each other.

[0093] The second grooved member 44 is formed in a U-shape when viewed from the side, and more specifically, in a J-shape when viewed from the side. That is, the top side of the first grooved member 43 of the second grooved member 44 is short, and the rear side is long. A slit 44a is formed in the second grooved member 44, which can be inserted into the slit 43c of the first grooved member 43. The second grooved member 44 is arranged laterally in a snap-fit ​​manner with the three-section first grooved member 43. The second grooved member 44 includes a second grooved member 44A disposed on the top side of the first grooved member 43, and a second grooved member 44B disposed on the rear side of the first grooved member 43.

[0094] like Figure 13 As shown, the rear end 41b of the inclined portion 41 is folded back toward the front end 41a, allowing the insertion portion 43d of the base portion 42 to be inserted.

[0095] In addition, such as Figure 14 As shown, the front end 41a of the inclined surface 41 can be folded back toward the rear end 41b and inserted into the slit 43c of the first grooved member 43 for the second grooved member 44A to engage.

[0096] Based on the above, it is possible to assemble Figure 12 The ramp component 40 is shown. Furthermore, the assembly structure of the ramp component 40 is not limited to this.

[0097] Thus, in the third embodiment described above, as Figure 9As shown, casters 102 are provided on the bottom surface of the bundled object 100, and a ramp component 40, made of corrugated cardboard, is housed in the bundle box 2 and is used when removing the bundled object 100. According to this structure, by utilizing the ramp component 40, it is easier to remove the relatively light bundled object 100 from the bundle box 2, unlike the heavier bundled object 100, which is nearly 1 ton, by using the protrusion 101 to lift and transport it with the aid of a crane, in terms of safety management.

[0098] Furthermore, in this embodiment, a pair of first angle members 21 are assembled in a grid pattern within multiple box-fixing components 20. According to this structure, even without the support platform 30, vibrations during transport of the bundled object 100 in the X-axis direction can be suppressed.

[0099] While preferred embodiments of the present invention have been described and illustrated above, they should be understood as illustrative examples and not as limitations thereof. Additions, omissions, substitutions, and other modifications can be made without departing from the scope of the invention. Therefore, the present invention should not be considered limited by the foregoing description, but rather by the scope of the claims.

[0100] For example, in the above embodiment, a lifting eye nut is exemplified as the protrusion 101, but the structure is not limited to this. For example, other protruding structures (e.g., the suction tube shown by reference numeral 103) can also be used as the protrusion 101. As other protruding structures, any protrusion 101 that is located on the upper part of the packaged object 100 and can be contacted in the horizontal direction by the vertical portion 21b of the first angle member 21 of the box fixing member 20.

[0101] Additionally, for example, in the above embodiment, the bundling body 1 suppresses movement in the Y-axis direction at the upper part of the bundled object 100 and suppresses movement in the X-axis direction at the lower part of the bundled object 100, but is not limited to this structure. For example, in Figure 4 In the example shown, the box-mounted fixing member 20 can also be made to contact the short side of the bundled object 100 to suppress the movement of the bundled object 100 in the Y-axis direction. Furthermore, when viewed vertically, the long side of the bundled object 100 can be fixed at the top, and the short side at the bottom. Moreover, if the box-mounted fixing member 20 and the support platform 30 contact the four sides of the bundled object 100, there is no restriction on the vertical height. Furthermore, at the same height, the box-mounted fixing member 20 cannot be fixed to the inside of the bundled box 2, thus avoiding this situation. Additionally, without the protrusion 101, to fix either the upper or lower part of the hexahedron of the bundled object 100 in the X-axis direction and the other in the Y-axis direction, for example, it is also possible to... Figure 7 as well as Figure 8 In the example shown, the box fixing member 20, which is located on the outside of the protrusion 101 in the Y-axis direction, is configured to contact the upper side of the bundled object 100 in the X-axis direction. In addition, the second truss 32 is fixed in the Y-axis direction.

[0102] Alternatively, for example, in the above embodiment, the box fixing member 20 abuts against the side of the protrusion 101, but in the absence of the protrusion 101, the box fixing member 20 may also abut directly against the side of the bundled object 100.

[0103] Additionally, for example, the use of the internal fixing component 20 can also be applied to... Figure 4 as well as Figure 8 The bundle 1 shown is narrow in width along the X-axis direction.

[0104] Alternatively, for example, the internal fixing component 20 can also abut from the inside of the two protrusions 101, the outside of the two protrusions 101, and both sides of the two protrusions 101. These methods can be applied in any of the above embodiments, and their substitution and combination are free.
