Detailed Implementation

[0051] Next, with reference to the accompanying drawings, the present invention will be further described in detail below with reference to embodiments and specific examples, but the present invention is not limited to these embodiments and specific examples.

[0052] Furthermore, in the following explanation of the use of the accompanying drawings, it should be noted that the drawings are schematic, the scales of the dimensions are different from those in reality, and some parts other than those required in the explanation have been omitted for ease of understanding.

[0053] (1) Structure of the bundle

[0054] Figure 1 This is a general overall perspective view showing the bundling method using the bundling body 10 according to this embodiment. Figure 2 This is a schematic perspective view showing the tray 20 of the bundle 10 according to this embodiment. Figure 3 This is an exploded perspective view of box 30. Figure 4 (a) is a schematic perspective view of the limiting component 40. Figure 4Figure (b) illustrates the elastic deformation of the limiting component 40. The overall structure and bundling method of the bundle 10 will be described below with reference to the accompanying drawings.

[0055] The bundle 10 consists of a pallet 20, a box 30, and restraining components 40, such as... Figure 1 As shown, the packaged body 100 is placed on the pallet 20 with its lateral movement restricted by the limiting member 40, and then the box 30 is used to wrap the packaged body 100. Additionally, in Figure 1 In order to show the bundled body 100, the box 30 wrapped around the bundled body 100 is shown in dashed lines.

[0056] In this embodiment, the tray 20 is an example of a base plate, for example, such as Figure 2 As shown, it consists of: a wooden base plate component 21 forming the bottom surface, a wooden beam component 22 consisting of a plurality of longitudinal beams and transverse beams disposed on the base plate component 21, and a wooden top plate component 23 disposed on the beam component 22 and forming the top surface. Positioning components 24 for positioning the lower end of the box body 30 are provided at the four corners of the top plate component 23.

[0057] The box body 30 is composed of a cylindrical main body 31 made of corrugated cardboard and a cover 32 that closes the opening 31a at the top of the main body 31.

[0058] The main body 31 is large enough to accommodate an electronic device with casters 101 that is relatively heavy as the bundle 100. The lower and upper ends are open. When the bundle 100 is placed on the tray 20, it passes through the lower opening 31a and is positioned on the top plate member 23 of the tray 20 by the positioning member 24.

[0059] The cover 32 is a cover that seals the opening 31b at the upper end of the main body 31 that passes through the bundled body 100 and is made of corrugated cardboard.

[0060] Hereinafter, the box 30 will be referred to as box 30 without distinguishing between the main body 31 and the cover 32.

[0061] The limiting component 40 is a plate component made of a metal sheet capable of elastic deformation, such as... Figure 4 As shown in (a), it has a base 41 fixed to the top plate component 23 of the tray 20 and an opening 111 for accessing the bottom surface of the bundled body 100 (see reference). Figure 4 (b) Press down on the hook 42 that is raised from the tray 20 by the bundled body 100. Figure 4 As shown in (b), when the external force F acts in the horizontal direction, the limiting component 40 can be elastically deformed, and its material is high-strength steel.

[0062] (2) Bundling method of the bundled object

[0063] Figure 5 This is a cross-sectional schematic diagram illustrating the bundling method of the bundled body 100 using the bundled body 10. Figure 6 This is a partially enlarged view illustrating the placement of the bundle 100 onto the tray 20 using the limiting component 40. Figure 12 This is a cross-sectional schematic diagram showing the bundling method of the bundle 100 based on the bundle 200 with the buffer pad PD in a comparative example. Figure 13 This is a cross-sectional schematic diagram showing the change of the bundle 100 under horizontal impact in a comparative example of a bundle 200 with a buffer pad PD.

[0064] like Figure 12 As shown, in the comparative example, the bundle 200 uses a limiting member 40 to restrict the lateral movement of the lower end of the bundle 100 placed on the pallet 20, and the upper end is restricted from lateral movement by a buffer pad PD disposed between the bundle 100 and the box 30, thereby preventing lateral slippage of the bundle 100 during transport. On the other hand, the dimensions of the bundle 200 (in...) Figure 12 Increasing the width (represented by W1) by an amount corresponding to the thickness of the buffer pad PD may decrease loading efficiency.

[0065] In the bundle 200 equipped with cushioning pad PD, such as Figure 13 As shown, when subjected to a horizontal impact, only the buffer pad PD bears the impact on the bundled body 100. As indicated by the arrow in the figure, the upper end of the bundled body 100, where the buffer pad PD is located, is subjected to concentrated impact, and the bundled body 100 may also be damaged.

[0066] like Figure 5 As shown, in this embodiment, the bundling body 10 restricts the lateral movement of the lower end of the bundled body 100 placed on the tray 20 using a limiting member 40, while at the upper end, no cushioning pad PD is provided between the bundled body 100 and the box 30. Furthermore, compared to the comparative example with the cushioning pad PD, the gap G1 between the bundled body 100 and the box 30 is reduced (see reference). Figure 6 (a) Therefore, when subjected to an impact in the horizontal direction, the impact energy is borne by the tray 20 and the box 30.

[0067] like Figure 6 As shown in (a), the lower end of the bundle 100 is restricted to move laterally by entering a hole 111 in the base 110, which is the bottom surface of the bundle 100, through a limiting member 40 fixed to the top plate member 23 of the tray 20.

[0068] Specifically, the clearance between the limiting member 40 and the hole 111 of the base 110 of the bundled body 100 is set to be greater than the gap G1 between the inner surface 30a of the box 30 and the bundled body 100. Here, clearance refers to the amount of space or distance that two objects can move relative to each other. In this embodiment, the clearance between the hole 111 and the limiting member 40 is the amount of distance that the base 110 with the hole 111 can move relative to the limiting member 40 when the bundled body 10 is subjected to a horizontal impact and moves laterally. That is, it is the amount of elastic deformation δ of the limiting member 40 when the edge 111a of the hole 111 contacts the limiting member 40 due to the horizontal movement of the bundled body 100, in addition to the gap G2 between the hole 111 and the limiting member 40.

[0069] like Figure 4 As shown in (b), the limiting member 40 is threadedly fixed to the top plate member 23 of the tray 20, and when subjected to a horizontal impact force, it can elastically deform in the horizontal direction with its base 41 as the reference point. In this embodiment, as an example, as... Figure 6 As shown in (a), the width L1 of the hole 111 minus the plate thickness t of the limiting member 40 is set to 6.8 mm, and the gap G2 between the hole 111 and the limiting member 40 is set to 6.8 mm (the gap on one side is 3.4 mm). The gap G1 between the inner surface 30a of the box body 30 and the bundled body 100 is set to 5 mm. The plate thickness t of the limiting member 40 is set to 1.6 mm, which is thinner than the plate thickness (2.3 mm) of the base body 110, so that the limiting member 40 can easily be elastically deformed in the horizontal direction when it is subjected to a horizontal impact force.

[0070] Specifically, when the bundle 10 containing the bundled object 100 collides horizontally at a speed of 4.8 km / h, the elastic deformation δ of the restraining component 40 becomes 1.6 mm or more. For example... Figure 6 As schematically shown in (b), the bundled body 100 moves horizontally on the pallet 20 without being restricted by the restraining member 40, and makes surface contact with the inner surface 30a of the box 30 on the entire surface of the bundled body 100.

[0071] (3) Impact absorption of the bundle body

[0072] Figure 7 This is a diagram showing the horizontal impact test of the bundle 10. Figure 8 This is a graph representing the amount of elastic deformation of the restraint component 40 during a horizontal impact test. Figure 9 This diagram shows the contact between the bundled object 100 and the inner surface 30a of the housing 30 during a horizontal impact test. Figure 10 This diagram illustrates the state of the bundled object 100 as it moves horizontally on the pallet 20 during a horizontal impact test, contacting the inner surface 30a of the box 30. Figure 11This is a diagram showing the change of the bundle 100 when it is subjected to a horizontal impact force in the bundle 300 of the comparative example where the limiting member 40 is not elastically deformed.

[0073] For the bundle 10 involved in this embodiment, the implementation is as follows: Figure 7 The horizontal impact test shown was used to evaluate the impact absorption of the bundle 10.

[0074] According to the bundle 10 of the present embodiment, since a pallet 20 with a wooden beam member 22 consisting of a plurality of longitudinal beams and cross beams is provided between the bottom plate member 21 and the top plate member 23 on the bottom side, it can be transported using a forklift.

[0075] Furthermore, during the distribution phase, such as in a warehouse, the bundles 10 are handled with a forklift while being held horizontally, and then stacked against a wall to align them. At this time, the ends of the pallet 20 and the sides of the box 30 may be subjected to horizontal impacts, causing the bundles 100 to tilt on the pallet 20, resulting in localized large impacts.

[0076] Example

[0077] like Figure 7 As shown, the horizontal impact test was conducted as follows: the bundle 10 was secured to the sliding platform 50 with a strap (not shown), and the sliding platform 50 was slid horizontally at a speed of 4.8 km / h, causing it to collide with the support 60. The bundle 10 was then secured by the box 30 while the bundle 100 was placed on the tray 20 and its lateral movement was restricted by the limiting member 40. In this horizontal impact test, the bundle 10 was subjected to a speed variation of 4.8 km / h in the horizontal direction.

[0078] exist Figure 8 In the middle, the use of time is shown. Figure 7 The method shown was used to measure the elastic deformation δ (mm) of the restraint component 40 during a horizontal impact test. Additionally, in Figure 8 The figure shows the elastic deformation of one of the four limiting members 40 fixed to the tray 20, but the other three limiting members 40 all show the same elastic deformation.

[0079] according to Figure 8Approximately 0.008 seconds after the collision (refer to A in the figure), the bundled body 100 moves horizontally within the gap G2 of the hole 111 without contacting the restraining member 40, and no elastic deformation of the restraining member 40 occurs. Then, as the bundled body 100 moves horizontally, the edge 111a of the hole 111 formed in the base 110 of the bundled body 100 contacts the restraining member 40, thereby causing the restraining member 40 to undergo an elastic deformation of approximately 16 mm approximately 0.03 seconds after the collision (refer to B in the figure), and then the amount of deformation of the restraining member 40 decreases over time.

[0080] That is, when the pallet 20 on which the bundle 100 is placed collides in the horizontal direction at a specified speed (4.8 km / h in the horizontal direction), the elastic deformation δ of the limiting member 40 in the horizontal direction is greater than the horizontal movement of the bundle 100.

[0081] exist Figure 9 The relationship between China and time demonstrates the use of Figure 7 The method shown was used to measure the changes in the distance between the lower and upper ends of the bundled body 100 and the inner surface 30a of the box 30 during a horizontal impact test. According to... Figure 9 The distance between the upper end of the bundled body 100 and the inner surface 30a of the box 30 decreases approximately 0.025 seconds after the collision (refer to A in the figure), and the distance between the lower end of the bundled body 100 and the inner surface 30a of the box 30 decreases approximately 0.027 seconds after the collision (refer to B in the figure), with a time difference of 0.002 seconds (2 msec). That is, the upper and lower ends of the bundled body 100 collide with the inner surface 30a of the box 30 with a time difference of less than 10 msec.

[0082] Thus, when the pallet 20 containing the bundled body 100 collides horizontally at a specified speed (4.8 km / h in the horizontal direction), the upper end of the bundled body 100 contacts the inner surface 30a of the box 30 earlier than the lower end of the bundled body 100 contacts the inner surface 30a of the box 30.

[0083] exist Figure 11 The diagram shows the deformation of the bundle 100 when it is subjected to a horizontal impact force in a comparative example where the bundle 100 moves horizontally and the edge 111a of the hole 111 contacts the limiting member 40 without elastic deformation.

[0084] When the limiting component 40 does not deform elastically, such as Figure 11As shown, the gap G2 between the horizontal movement restriction member 40 and the hole 111 of the bundled body 100 on the tray 20 is large, and the upper end is inclined with the contact part between the restriction member 40 and the hole 111 as the base point, as shown by the arrow in the figure, and is locally subjected to a large impact.

[0085] exist Figure 10 The text shows the use of... Figure 7 The method shown was used to test the horizontal impact state in which the bundled body 100 moved horizontally on the pallet 20 and came into contact with the inner surface 30a of the box 30.

[0086] According to the bundling body 10 of this embodiment, by setting the clearance between the limiting member 40 and the hole 111 of the bundled body 100 to be greater than the gap G1 between the inner surface 30a of the box 30 and the bundled body 100, the bundled body 100 will not be restricted by the limiting member 40 on the tray 20 and will not move laterally. As shown by the arrow in the figure, the bundled body 100 makes surface contact with the inner surface 30a of the box 30 on the entire surface.

[0087] (4) Function and effect of the bundle body

[0088] In the bundle 10 of this embodiment, the clearance between the limiting member 40 and the hole 111 of the base 110 of the bundled body 100 is set to be greater than the gap G1 between the inner surface 30a of the box 30 and the bundled body 100. The clearance includes the elastic deformation of the limiting member 40 when the edge 111a of the hole 111 contacts the limiting member 40 due to horizontal movement of the bundled body 100. When subjected to a horizontal impact, the bundled body 100 moves horizontally on the tray 20 by at least the amount of the clearance and abuts against the surface of the box 30.

[0089] The embodiments of the present invention described above are provided for illustrative purposes. Furthermore, these embodiments do not encompass the entirety of the invention, nor do they limit the invention to the disclosed methods. It will be apparent to those skilled in the art that various modifications and variations will be readily understood.
