[0008] [First embodiment] A pallet aid 10 according to a first embodiment will be described with reference to Fig. 1 to Fig. 9. As shown in Fig. 1, the pallet aid 10 is attached to a pallet 100 and used when transporting cylindrical cargo 90. The cylindrical cargo 90 may be, for example, a roll of a film, resin sheet, metal foil, paper, or other sheet, or a cylinder or columnar body.

[0009] The pallet 100 shown in Fig. 2 is, for example, a resin pallet, and has multiple beams 102 on the underside of a rectangular deck board 101, with the spaces between the beams 102 forming fork insertion spaces 103. The beams 102 are arranged at the four corners and the center of each side edge of the pallet 100, as well as at the center of the pallet 100. The deck board 101 is fitted with multiple ribs 101A extending vertically and horizontally, and has multiple through holes 101B formed therein.

[0010] As shown in FIG. 3, the pallet auxiliary tool 10 has a rectangular plate-shaped lower divided body 11 and a trapezoidal block-shaped upper divided body 30. The planar shape of the lower divided body 11 is one size larger than the planar shape of the pallet 100 divided into four equal parts, and the four lower divided bodies 11 cooperate to cover almost the entire upper surface of the pallet 100. Of the four lower divided bodies 11, two lower divided bodies 11 located on each diagonal line of the pallet 100 have the same shape, and adjacent lower divided bodies 11 vertically and horizontally have line-symmetric shapes. In addition, the portions of each lower divided body 11 located at the corners of the pallet 100 are chamfered to form rounded chamfered portions 11A. Hereinafter, the longitudinal direction of the lower divided body 11 is referred to as a first horizontal direction H1, and the transverse direction is referred to as a second horizontal direction H2.

[0011] The lower divisional body 11 will be described in detail using the lower divisional body 11 on the left front side in FIG. 3 as an example. As shown in FIG. 4, the lower divisional body 11 has a rectangular main plate portion 12, and a bank portion 13 that is stepped is formed on the long side of the main plate portion 12 having the chamfered portion 11A. The bank portion 13 is provided with four grooves 14 and one step portion 15 extending in the second horizontal direction H2. The step portion 15 is arranged at the end opposite to the chamfered portion 11A, and the step surface is flush with the upper surface of the main plate portion 12. The bottom surfaces of the four grooves 14 are also flush with the upper surface of the main plate portion 12. Three of the four grooves 14 are arranged at equal intervals between the position near the chamfered portion 11A of the bank portion 13, the center portion, and between them. The remaining groove 14 is disposed closer to the step 15, and the distance between the step 15 is approximately the same as the distance between the three grooves 14 on the chamfered portion 11A side. In addition, the width of this groove 14 is slightly larger than the three grooves 14 on the chamfered portion 11A side.

[0012] In addition, when four lower divisional bodies 11 are placed on the pallet 100, the step portions 15 of two lower divisional bodies 11 lined up on the long side are adjacent to each other, forming a pseudo groove 15M having approximately the same width as the groove 14 closer to the step portion 15.

[0013] As shown in FIG. 5, a plurality of protrusions 17 that fit into through holes 101B (see FIG. 2) of pallet 100 are formed on the lower surface of lower divisional body 11. Also, hanging parts 20 that hang down vertically are formed on the lower surface of lower divisional body 11 on two sides extending lengthwise and widthwise from chamfered portion 11A, i.e., on two sides along the outer edge of pallet 100. As shown in FIG. 6, lower divisional body 11 is placed on pallet 100 so that hanging parts 20 abut the outer wall of pallet 100, whereby lower divisional body 11 is positioned relative to pallet 100. In this state, the long side part of lower divisional body 11 on bank part 13 side protrudes outward from the outer edge of pallet 100 in second horizontal direction H2. This part protruding outward from pallet 100 (i.e., the part outside the inner side surface of hanging part 20 on the long side) is appropriately referred to as "protruding part 25".

[0014] The vertical length of hanging portion 20 on the short side is approximately the same as the plate thickness of main plate 12, and when lower section 11 is attached to pallet 100, the lower surface is disposed at approximately the same height as the upper end of fork insertion space 103. The outer lower edge of hanging portion 20 on the short side forms tapered portion 20T which approaches the inside as it extends downward. In addition, the vertical length of the end of hanging portion 20 on the short side on the chamfered portion 11A side is approximately 2 to 3 times the plate thickness of main plate 12.

[0015] Hanging portion 20 on the long side is two to three times wider and three to six times longer in the vertical direction than hanging portion 20 on the short side. Hanging portion 20 on the long side is disposed inward from the outer edge of lower split body 11. The underside of the portion of lower split body 11 outer than hanging portion 20 (hereinafter referred to as "outer edge underside 25A" as appropriate) is positioned approximately flush with the underside of the end portion of hanging portion 20 on the short side near chamfered portion 11A, and a step is formed between hanging portion 20.

[0016] Additionally, hanging portion 20 on the long side and the midway portion in the longitudinal direction of the outer portion thereof form a notch 21 that is recessed upward. This notch 21 is disposed in the same position as fork insertion space 103 when lower divided body 11 is attached to pallet 100, and its lower surface is disposed at approximately the same height as the upper end of fork insertion space 103. Also, similar to tapered portion 20T of hanging portion 20 on the short side, tapered portion 21T that approaches inward as it extends downward is formed on the outer lower edge of this notch 21.

[0017] Next, the upper divided body 30 will be described. As shown in FIG. 7A, the upper divided body 30 is substantially trapezoidal when viewed from the first horizontal direction H1, and has an upper surface 31, a lower surface 32, a slope 33 (corresponding to a "rolling restriction slope"), and an outer surface 34. The upper surface 31 is a long and thin rectangular shape extending in the first horizontal direction H1, and its width is about 1 / 2 to 1 / 3 of the width of the bank portion 13 (see FIG. 3) of the lower divided body 11. The slope 33 extends from the inner long side of the upper surface 31, and the outer surface 34 extends vertically downward from the outer long side. The slope 33 in this embodiment is curved in an arc shape so as to fit the outer peripheral surface of the cylindrical load 90 (see FIG. 1).

[0018] As shown in FIG. 7B, the lower surface 32 of the upper division body 30 has two recesses 32A arranged side by side in the first horizontal direction H1. The recesses 32A are flattened rectangular parallelepipeds and open to the outer surface 34. The length of the recesses 32A in the second horizontal direction H2 is approximately the same as the width of the bank portion 13 of the lower division body 11, and the length of the recesses 32A in the first horizontal direction H1 is approximately the same as the distance between the grooves 14 on the chamfered portion 11A side of the bank portion 13 of the lower division body 11. These two recesses 32A form three protrusions 32B on the outer side of the lower surface 32 of the upper division body 30, and the intervals between the three protrusions 32B are the same as the intervals between the three grooves 14 on the chamfered portion 11A side of the bank portion 13 of the lower division body 11.

[0019] As shown in FIG. 3, the upper divisional body 30 is placed on the lower divisional body 11 with the inclined surface 33 facing inward in the second horizontal direction H2. Specifically, the upper divisional body 30 is disposed in a position where the three protrusions 32B fit into the three grooves 14 on the chamfered portion 11A side of the lower divisional body 11. Then, the protrusions 32B engage with the grooves 14 (in other words, the recessed portion 32A engages with the bank portion 13), and the upper divisional body 30 is positioned in the first horizontal direction H1 with respect to the lower divisional body 11. In addition, since the inner side surface of the recessed portion 32A on the inner side in the second horizontal direction H2 faces the outer side surface of the bank portion 13 on the inner side in the second horizontal direction H2, the movement of the upper divisional body 30 outward in the second horizontal direction H2 is also restricted, and even if the upper divisional body 30 receives a cylindrical load 90 in the second horizontal direction H2, the upper divisional body 30 is prevented from coming off.

[0020] Furthermore, the upper divisional body 30 is attached across the two lower divisional bodies 11. Specifically, the three protrusions 32B are received in the grooves 14 near the step portions 15 of each lower divisional body 11 and in the pseudo grooves 15M formed by adjacent step portions 15, and the upper divisional body 30 is positioned relative to the two lower divisional bodies 11. When the upper divisional body 30 is placed on the lower divisional body 11, the outer surface 34 of the upper divisional body 30 and the outer surface of the lower divisional body 11 are approximately flush with each other.

[0021] 8 and 9, the height of the upper divisional body 30 is approximately the same as the distance between the placement surface on which the pallet 100 is placed and the outer edge lower surface 25A of the lower divisional body 11 when the lower divisional body 11 is placed on the pallet 100. The width of the upper surface 31 of the upper divisional body 30 in the second horizontal direction H2 is approximately the same as or slightly smaller than the width of the outer edge lower surface 25A in the second horizontal direction H2. As a result, when the upper divisional body 30 is placed under the overhanging portion 25 of the lower divisional body 11 with the inclined surface 33 facing outward in the second horizontal direction H2, it fits between the placement surface on which the pallet 100 is placed and the outer edge lower surface 25A of the lower divisional body 11, and the upper divisional body 30 can support the overhanging portion 25 of the lower divisional body 11. Furthermore, when upper divisional body 30 is pushed in until it abuts against hanging portion 20 , most of slope 33 becomes exposed outside overhanging portion 25 .

[0022] Next, the action and effect of the pallet auxiliary tool 10 of this embodiment will be described. The pallet auxiliary tool 10 of this embodiment is used as follows. When loading cargo 90 onto pallet 100, first, the four lower divisional bodies 11 are placed on pallet 100 so that hanging parts 20 abut or are close to the outer surface of pallet 100. At this time, protrusions 17 on the lower surfaces of lower divisional bodies 11 are received in and engaged with through holes 101B of pallet 100, and lower divisional bodies 11 are positioned.

[0023] Next, the upper divisional body 30 is attached to one long side of the pallet auxiliary tool 10. The upper divisional body 30 is arranged at three locations: on the chamfered portion 11A side of each of the two lower divisional bodies 11 arranged on one long side, and at a position spanning the two lower divisional bodies 11, with the protrusions 32B being received in the grooves 14 or pseudo grooves 15M of the lower divisional body 11. Then, a cylindrical cargo 90 is placed horizontally on the lower divisional body 11. The cylindrical cargo 90 may be lowered from above, or may be rolled onto the other long side of the pallet auxiliary tool 10.

[0024] After all the cargo 90 has been placed, the upper divisional body 30 is attached to the other long side of the pallet auxiliary device 10. At this time, the upper divisional body 30 is placed on the lower divisional body 11 by inserting the tip of the slope 33 obliquely under the cargo 90 and then returning it to a horizontal position. The upper divisional body 30 on the other long side is also placed in three places, similar to the one long side (see FIG. 1). This allows the slope 33 of the upper divisional body 30 to be applied to the circumferential surface of the cargo 90, preventing the cargo 90 from rolling. This completes the loading of the cargo 90.

[0025] Next, when the cargo 90 is to be lowered, the upper divisional body 30 on the other long side of the pallet auxiliary tool 10 is removed, and the upper divisional body 30 is fitted under the overhanging portion 25 of the lower divisional body 11 with the slope 33 facing outward in the second horizontal direction H2 (see FIG. 8). Then, the cylindrical cargo 90 is rolled to the other long side of the pallet auxiliary tool 10, and is lowered over the bank portion 13. At this time, since the upper divisional body 30 supports the overhanging portion 25 of the lower divisional body 11, a load is applied only to the outer edge of the lower divisional body 11, and the lower divisional body 11 can be prevented from tilting or being damaged. In addition, since most of the slope 33 of the upper divisional body 30 is exposed from the lower divisional body 11, the slope 33 of the upper divisional body 30 can be used as a slope depending on the diameter of the cargo 90.

[0026] When all the cargo 90 has been unloaded, the remaining upper divisional body 30 and the lower divisional body 11 are removed. This completes the unloading of the cargo 90. Note that the loading and unloading of the cargo 90 may be performed with the upper divisional bodies 30 disposed on both of the pair of long sides.

[0027] In this way, according to the pallet aid 10 of this embodiment, by attaching the pallet aid 10 to a general pallet 100, cylindrical cargo 90 can be stably loaded, making it possible to transport cylindrical cargo while maintaining the versatility of the pallet, rather than manufacturing a pallet specifically for cylindrical cargo.

[0028] In addition, the pallet auxiliary device 10 can be separated into a lower section 11 that engages with the pallet 100 and an upper section 30 having a slope 33 that is fitted to the outer peripheral surface of the luggage 90. Therefore, the upper section 30 can be attached after the luggage 90 is loaded, and the upper section 30 can be removed before the luggage 90 is unloaded, improving the efficiency of loading and unloading the luggage 90.

[0029] Moreover, the lower section 11 has a protruding portion 25 that protrudes laterally from the pallet 100, and the upper portion of the slope 33 of the upper section 30 is arranged on the protruding portion 25 (this state corresponds to the "expanded state"), so that the loading of the luggage 90 can be stabilized even if part of the luggage 90 protrudes from the pallet 100.

[0030] Furthermore, if the entire upper section 30 were arranged on the protruding portion 25, there would be a concern that when the cargo 90 was received, a large load would be placed on the part of the pallet auxiliary device 10 (especially the lower section 11) that protrudes laterally from the pallet, making it more susceptible to damage. However, since part of the upper section 30 is arranged on the pallet 100, the load is transmitted vertically to the pallet 100 via the lower section 11, making it easier to distribute the load of the upper section 30 and the cargo 90 across the pallet 100, and making the pallet auxiliary device 10 less susceptible to damage.

[0031] In addition, since the lower divisional body 11 covers the upper surface of the pallet 100 and supports the cargo 90, the load of the cargo 90 presses the lower divisional body 11 toward the pallet 100, preventing the lower divisional body 11 from coming off during use. Furthermore, in this embodiment, the upper surface of the pallet 100 is not covered by one large lower divisional body, but is covered by four lower divisional bodies 11, so that each lower divisional body 11 is small and easy to handle, and the work of attaching the lower divisional bodies 11 is facilitated. Furthermore, since the upper divisional body 30 is attached across the two lower divisional bodies 11, the lower divisional bodies 11 are connected to each other by the upper divisional body 30, making it even more difficult for the lower divisional bodies 11 to become misaligned.

[0032] [Second embodiment] The pallet auxiliary tool 10 of this embodiment is different from the pallet auxiliary tool 10 of the first embodiment in the shape of the lower divided body 11W. As shown in Fig. 10, the lower divided body 11W of this embodiment has three auxiliary grooves 29 formed in the bank portion 13. The three auxiliary grooves 29 are each disposed at a position shifted toward the step portion 15 side from the three grooves 14 on the chamfered portion 11A side, and extend from the inner edge to the center in the second horizontal direction H2 of the bank portion 13. The three auxiliary grooves 29 can position the upper divided body 30 in the same way as the three grooves 14 on the chamfered portion 11A side (see Fig. 11).

[0033] According to the pallet auxiliary device 10 of this embodiment, it is possible to selectively attach the upper section 30 to two different positions in the second horizontal direction H2 of the lower section 11W (see Figures 11 and 12), so that the loading of the cargo 90 can be stabilized by changing the position of the upper section 30 depending on the diameter and number of the cylindrical cargo 90.

[0034] [Other embodiments] The lower divisional body 11 may be configured so that one piece covers substantially the entire upper surface of the pallet 100.

[0035] The lower section 11 may be arranged only on the outer edge of the pallet 100 and not come into contact with the lower end of the cargo 90 placed thereon.

[0036] In the above embodiment, the pallet auxiliary tool 10 is separable into the lower divisional body 11 and the upper divisional body 30, but they may be integrated together.

[0037] The entire upper divisional body 30 may be disposed on the protruding portion 25 of the lower divisional body 11 .

[0038] As shown in FIG. 13, the lower divisional body 11 may be formed with a slope 11S that is continuous with the slope 33 of the upper divisional body 30.

[0039] 14, the height of the upper divisional body 30 may be the same as the distance from the placement surface of the pallet 100 to the top surface of the bank portion 13 of the lower divisional body 11, and the outer surface 34 of the upper divisional body 30 may be provided with a support portion 35 that fits under the protruding portion 25 of the lower divisional body 11. In this case, the inclined surface 33 is more likely to function as a slope.

[0040] In the above embodiment, the pallet auxiliary tool 10 and the pallet 100 are engaged with each other in a concave-convex manner, but they may be engaged with each other by friction.

[0041] In the above embodiment, the groove 14 formed in the bank portion 13 of the lower division body 11 and the protrusion 32B on the underside of the upper division body 30 are engaged in a concave-convex manner (the bank portion 13 of the lower division body 11 and the recess 32A on the underside of the upper division body 30 are engaged in a concave-convex manner), but the underside of the upper division body 30 may be flat, and the lower division body 11 may be formed with a recess or a protrusion that engages with the lower end portion of the upper division body 30. In this case, the lower end portion of the upper division body 30 and the recess or the protrusion of the upper division body 30 correspond to the concave-convex engagement portion.

[0042] Also, the upper surface of the lower divisional body 11 may be flat, and the upper divisional body 30 may be formed with a recess or protrusion that engages with the upper end portion of the lower divisional body 11. For example, a configuration in which the upper divisional body 30 covers the corners of the lower divisional body 11 and is provided with a protrusion that faces the corners is conceivable. In this case, the upper end portion of the lower divisional body 11 and the recess or protrusion of the upper divisional body 30 correspond to the recess-projection engagement portion. Also, the recess referred to here may be a recess with a bottom, or may be a through hole without a bottom.

[0043] <Additional Notes> The following describes the feature groups extracted from the above-described embodiments, while indicating their effects, etc., as necessary. Note that, in the following, for ease of understanding, the corresponding configurations in the above-described embodiments are appropriately indicated in parentheses, etc., but these feature groups are not limited to the specific configurations indicated in parentheses, etc.

[0044] [Feature 1] A pallet support device (10) that is placed on a pallet (100) and regulates the rolling of a cylindrical load (90), The pallet auxiliary device (10) has a rolling restriction slope (33) that is applied to the outer peripheral surface of the luggage (90), and can be used in an expanded state in which the upper part of the rolling restriction slope (33) protrudes laterally from the pallet (100).

[0045] According to the pallet auxiliary device of feature 1, cylindrical cargo can be stably loaded by attaching the pallet auxiliary device to the pallet, so it is possible to transport cylindrical cargo while maintaining the versatility of the pallet. Moreover, since the upper part of the rolling restriction slope applied to the outer periphery of the cargo can be used in a state where it protrudes laterally from the pallet, the cargo can be stably loaded even if part of the cargo protrudes from the pallet.

[0046] [Feature 2] an upper division body (30) and a lower division body (11) which are stacked vertically to form a pallet auxiliary tool (10) and which are separable from each other; an engaging portion (17, 20) that protrudes from the lower surface of the lower division body (11) and engages with an engaged portion on the upper surface of the pallet (100) or an outer surface of the pallet (100) in the expanded state; a concave-convex engagement portion (13, 14, 15, 32A, 32B) provided on the overlapping surfaces of the lower division body (11) and the upper division body (30) and engaging with each other, The pallet auxiliary tool (10) according to feature 1, wherein the rolling restriction slope (33) is disposed on the upper division body (30).

[0047] According to the pallet auxiliary tool of feature 2, the lower divisional body that engages with the pallet and the upper divisional body on which the rolling restriction slope is arranged can be separated, so that the upper divisional body can be attached after loading the cargo and removed before unloading the cargo, improving the efficiency of cargo loading and unloading operations. The rolling restriction slope may be arranged entirely on the upper divisional body, or a portion of the slope may be arranged on the upper divisional body and the remainder on the lower divisional body. The engaged portion on the top surface of the pallet may be a concave shape with a bottom or a through hole without a bottom.

[0048] [Feature 3] The pallet auxiliary device (10) described in feature 2, wherein the concave-convex engagement portions (13, 14, 15, 32A, 32B) of the lower division body (11) are capable of positioning the upper division body (30) so as to straddle the two lower division bodies (11).

[0049] According to the pallet auxiliary tool of feature 3, when multiple lower division bodies are placed on a pallet, the lower division bodies are also positioned relative to each other by the upper division body, making the lower division bodies even less likely to become misaligned.

[0050] [Feature 4] The pallet auxiliary device (10) described in feature 2 or 3, wherein the concave-convex engagement portion (13, 14, 15, 29, 32A, 32B) of the lower section (11) is capable of selectively attaching the upper section (30) to one of a first position where the rolling control slope (33) protrudes from the pallet (100) and a second position where the amount of protrusion of the rolling control slope (33) from the pallet (100) is smaller than the first position or the entire rolling control slope (33) is positioned on the pallet (100).

[0051] According to the pallet auxiliary device of feature 4, the position of the upper section can be changed depending on the diameter and number of cylindrical cargo items, thereby stabilizing the loading of the cargo items.

[0052] [Feature 5] an engaging portion (17, 20) that protrudes from the lower surface of the pallet auxiliary device (10) and engages with an engaged portion on the upper surface of the pallet (100) or an outer surface of the pallet (100) in the expanded state; A pallet auxiliary device (10) described in any one of features 1 to 4, wherein when the pallet auxiliary device (10) is positioned by the engagement portions (17, 20), a portion of the rolling control slope (33) protrudes laterally from the pallet (100), and all but a portion of the rolling control slope (33) is located on the pallet (100).

[0053] If the entire rolling restriction slope protrudes laterally from the pallet, there is a concern that the part of the pallet auxiliary device that protrudes laterally from the pallet will be subjected to a large load when a load is received, making it more likely to be damaged, but according to the pallet auxiliary device of feature 5, all but a part of the rolling slope is located on the pallet, making it easier to distribute the load on the pallet and less likely to be damaged. The engaged portion on the top surface of the pallet may be a concave shape with a bottom, or a through hole without a bottom.

[0054] [Feature 6] A pallet set comprising the pallet auxiliary tool (10) according to any one of features 2 to 4 and the pallet (100), A pallet set in which multiple lower segments (11) work together, or one lower segment (11) covers the upper surface of the pallet (100), and the lower segment (11) supports the cargo (90).

[0055] According to the pallet set of feature 6, the lower section covers the upper surface of the pallet and supports the cargo, so that the load of the cargo presses the lower section against the pallet, preventing the lower section from coming off during use.

[0056] [Feature 7] A pallet set comprising the pallet auxiliary tool (10) according to any one of features 2 to 4 and the pallet (100), the lower divisional body (11) has a protruding portion (25) that protrudes laterally from the pallet (100) when positioned by the engaging portions (17, 20), The upper section (30) is a pallet set in which at least a portion of the upper section (30) can be fitted between the support surface on which the pallet (100) is placed and the protrusion (25) of the lower section (11), with the rolling control slope (33) facing toward the outside of the pallet (100).

[0057] According to the pallet set of feature 7, when unloading the cargo, the upper division can be fitted between the surface on which the pallet is placed and the overhang of the lower division. In this case, if the rolling restriction slope is located to the side of the lower division, it can be used as a slope when rolling the cargo down. In addition, since the overhang of the lower division is supported by the upper division, the load on the overhang can be distributed.
