Description

  The present invention relates to a pallet for supporting a load.

  As shown in Patent Document 1, when a load is loaded on a pallet, stretch wrapping is performed to prevent the load from collapsing or moving. In stretch wrapping, a stretch film having adhesiveness excellent in stretchability is wound around a pallet from a load in a tensioned state. On the pallet on which the stretch film is wound, ribs that prevent the stretch film wound around the load from being displaced are formed along a direction substantially parallel to the periphery of the deck board.

  Moreover, as shown in Patent Document 2, pallets loaded with loads are placed side by side near the pallet loaded with loads first. Some pallets arranged side by side as described above are provided with vertical ribs that prevent a pallet placed later from riding on an outer peripheral rib of the pallet placed first. The vertical ribs connect the upper deck board and the lower deck board along a direction substantially orthogonal to the periphery of the deck board.

  In the pallet, a second rib having the same height as the first rib may be formed on the outer surface of the corner beam portion in parallel with the extending direction of the first rib.

  According to the above configuration, the strength of the corner beam portion is strengthened together with the first rib, and the second rib comes into contact with an obstacle before the first rib, thereby protecting the first rib. it can.

In the pallet, a taper portion may be further formed at an upper surface side corner portion of the first rib.
According to the above configuration, the outer peripheral rib of the pallet to be transported may further enter the gap portion. In this case, the outer peripheral rib of the pallet to be transported is an upper side corner of the first rib. The tapered portion smoothly slips out of the gap portion.

Hereinafter, an embodiment of a pallet according to the present invention will be described with reference to the drawings.
As shown in FIGS. 1 and 2, the pallet 1 is a single-sided four-way pallet, and includes an upper deck board 11 on which a mounting surface 12 is formed, and a lower deck board 21 on which a grounding surface 22 is formed. The four corner beams 31 for connecting the upper deck board 11 and the lower deck board 21 are provided. Further, an intermediate beam portion 32 is formed between the two corner beam portions 31 adjacent to each other, and further, between the center portions of the upper deck board 11 and the lower deck board 21, that is, between the intermediate beam portions 32 and 32. A central girder 33 is formed. The pallet 1 is a synthetic resin pallet that is formed in a rectangular plate shape as a whole. The pallet 1 is made of synthetic resin material such as polypropylene or recycled polypropylene as a raw material, and is molded by, for example, integral injection molding.

  In the pallet 1, a first insertion port 34 into which a fork of a transport machine such as a forklift or a handlift is inserted is formed between the corner beam portion 31 and the intermediate beam portion 32 in the long side direction. Further, in the short side direction, a second insertion port 35 into which the fork of the transport machine is inserted is formed between the corner beam portion 31 and the intermediate beam portion 32.

  The upper deck board 11 has an upper surface serving as a placement surface 12 on which a cargo such as a cardboard box is placed, and a grid-like bar 14 is formed inside an annular outer surface portion 13. An upper surface side outer peripheral rib 15 is formed on the outer side surface portion 13 so as to protrude outward substantially flush with the mounting surface 12. The upper surface side outer peripheral rib 15 reinforces the outer surface portion 13 and protects, for example, an obstacle from directly hitting the outer surface portion 13.

  As shown in FIG. 2, the lower deck board 21 is formed so as to span a corner beam portion 31 and an intermediate beam portion 32. That is, the lower deck board 21 is formed to form a rectangular ring along the outer periphery. Further, the lower deck board 21 is formed in a cross shape so as to extend over the intermediate beam portion 32 and the central beam portion 33. Also on the lower deck board 21 formed along the outer periphery, lower-surface-side outer peripheral ribs 23 are formed so as to protrude outward substantially flush with the ground contact surface 22. The lower surface side outer peripheral rib 23 reinforces the outer surface portion 13 and protects, for example, an obstacle from directly hitting the outer surface portion 13.

  As shown in FIG. 3 (a), each corner beam 31 also has an upper surface side outer peripheral rib 15 at the upper end and a lower surface side outer peripheral rib 23 at the lower end. Each corner girder 31 has a circular arc surface whose outer surface 31a is chamfered and curved in the circumferential direction. On the outer side surface 31 a, a plurality of first ribs 41 are formed between the upper surface side outer peripheral rib 15 and the lower surface side outer peripheral rib 23. The plurality of first ribs 41 are formed to extend linearly in the thickness direction at the center of the arc surface. That is, the first rib 41 is provided perpendicular to the upper surface side outer peripheral rib 15 and the lower surface side outer peripheral rib 23. A first gap 42 is formed between the two first ribs 41 adjacent to each other. The first gap portion 42 is formed not only between the first ribs 41 but also between the upper surface side outer peripheral ribs 15.

  The first rib 41 reinforces each corner beam 31 in cooperation with the upper surface side outer peripheral rib 15 and the lower surface side outer peripheral rib 23, and prevents, for example, an obstacle from directly hitting the outer surface portion 13. In addition, among the plurality of first ribs 41, the lowermost first rib 41a is formed continuously with the lower surface side outer peripheral rib 23, and has a higher strength than when a gap is provided between them. Yes. Further, the lower first rib 41a is continuous with the lower surface side outer peripheral rib 23 without a gap so that the lower surface side outer peripheral rib 23 of one pallet 1 is placed on the other pallet when the pallet 1 is placed adjacently. 1 is suppressed from climbing on the lower surface side outer peripheral rib 23.

  3A, the upper surface side outer peripheral rib 15 and the lower surface side outer peripheral rib 23 are formed at substantially the same height, and the first rib 41 also includes the upper surface side outer peripheral rib 15 and the lower surface side outer peripheral rib. The ribs 23 are formed at substantially the same height. That is, assuming that the height of the upper surface side outer peripheral rib 15 is (H1), the height of the lower surface side outer peripheral rib 23 is (H2), and the height of the first rib 41 is (H3), (H1) ≈ (H2) ≈ The relationship (H3) is satisfied. In the corner portion 31, by arranging the heights of the ribs 23 and 41, a step is generated between the upper surface side outer peripheral rib 15 and the first rib 41, or the lower surface side outer peripheral rib 23 and the first rib 41 are There is no step between them. This prevents the lower surface side outer peripheral rib 23 of one pallet 1 from riding on the lower surface side outer peripheral rib 23 of the other pallet 1 when the pallets 1 are placed adjacent to each other.

  A stretch film 50 having adhesiveness excellent in stretchability enters the first gap portion 42 formed between the two first ribs 41 adjacent to each other to prevent collapse of the load. Accordingly, the stretch film 50 is locked to the corner 40 on the lower surface side of the first rib 41 with the first rib 41 portion serving as an inflection point. That is, as shown in FIGS. 3B and 4, when the pallet 1 is loaded with a load on the placement surface 12, the stretch film 50 is placed outside the load or the pallet 1 to prevent the load from collapsing. It is wound up multiple times while extending across the surface portion 13. As shown in FIG. 3B, the wound stretch film 50 is a synthetic resin film having a thickness of about 20 μm, and enters the first gap portion 42 in the portion of the outer surface portion 13, and the first rib 41. Is locked to the taper portion 40a on the upper surface side and the corner portion 40 on the lower surface side. Further, the stretch film 50 has both side edges in the longitudinal direction also enter the first gap 42, and even in the middle in the width direction, the stretch film 50 is stretched to bite into the first gap. Enter 42. In the stretch film 50, the first rib 41 portion is an inflection point, and the stretch film 50 is locked to the corner portion 40 on the lower surface side of the first rib 41, so that the stretch film 50 is prevented from being displaced and loosened.

  As shown in FIG. 3A, here, the plurality of first gap portions 42 are not provided uniformly over the entire thickness direction of the outer side surface 31 a of the corner beam portion 31, but are thicker. It is formed so as to be biased toward the upper surface deck board 11 side from the half in the vertical direction. Here, the plurality of first gap portions 42 are formed so as to be biased upward to a height of about 3/4 from the ground contact surface. The lower deck board 21 side is closer to the ground than half of the outer surface 31a in the thickness direction, and the amount of stretch film 50 wound around the loaded luggage 100 is small. It is because it becomes difficult to become a problem from the upper half of the thickness direction of 31a.

  In particular, the corner 40 on the lower surface side of the first rib 41 that holds the stretch film is formed in a shape close to a right angle. As a result, the stretch film 50 can bite into the corner portion 40 and be securely locked, and can be prevented from shifting with respect to the outer side surface portion 13. Moreover, the corner | angular part by the side of the upper surface of the 1st rib 41 is formed so that an obtuse angle may be made, and it is the taper part 40a which inclines toward the outer side from the upper surface side to the lower surface side. The first gap portion 42 is wider than the thickness of the upper surface side outer peripheral rib 15 and the lower surface side outer peripheral rib 23. Therefore, the upper surface side outer peripheral rib 15 and the lower surface side outer peripheral rib 23 that have entered the first gap portion 42 are disengaged so as to slide along the taper portion 40a. Of course, the corner portion 40 on the lower surface side may be formed with a tapered portion, and the first rib 41 may be trapezoidal as a whole. This is because the stretch film 50 can be tightly wound around the pallet 1 by providing an inflection point by the first rib 41.

  As shown in FIG. 3A, a second rib 43 is further formed on the outer surface 31 a of each corner beam 31 in parallel with the extending direction of the first rib 41. The heights (H4) of the second ribs 43 on both sides of the first rib 41 are also the height (H1) of the upper surface side outer peripheral rib 15, the height (H2) of the lower surface side outer peripheral rib 23, and the height of the first rib 41. This is substantially the same as (H3). The second rib 43 is formed to be continuous without providing a gap between the upper surface side outer peripheral rib 15 and the lower surface side outer peripheral rib 23. The second rib 43 reinforces each corner beam portion 31 in cooperation with the upper surface side outer peripheral rib 15, the lower surface side outer peripheral rib 23 and the first rib 41. Further, for example, an obstacle is protected from directly hitting the outer surface portion 13. Further, when the pallet 1 is placed adjacently, the lower surface side outer peripheral rib 23 of one pallet 1 is prevented from riding on the lower surface side outer peripheral rib 23 of the other pallet 1. Further, the lower second rib 43 is continuous with the lower surface side outer peripheral rib 23 without a gap, so that when the pallet 1 is placed adjacently, the lower surface side outer peripheral rib 23 of one pallet 1 is the other pallet. 1 is suppressed from climbing on the lower surface side outer peripheral rib 23.

  As shown in FIG. 4, the pallet 1 configured as described above is loaded with a load 100 such as cardboard aligned on the placement surface 12 of the upper deck board 11. Thereafter, the stretch film 50 is wound around the pallet 1 loaded with the luggage 100 by an automatic winding machine to prevent the cargo from collapsing. In general, the stretch film 50 is a film of about 20 μm having adhesiveness excellent in stretchability, and is stretched in multiple layers across the outer surface 13 of the load or pallet 1 while being stretched. Here, as shown in FIG. 3B, the first rib 41 can securely lock the wound up stretch film 50 by forming an inflection point in the stretch film 50. In particular, since the corner 40 on the lower surface side of the first rib 41 is formed in a shape close to a right angle, the wound up stretch film 50 is reliably locked. Therefore, for example, the stretch film 50 can be prevented from collapsing due to slippage and slackening.

  Further, as shown in FIG. 5, when the pallets 1 are conveyed by the conveyor, the first ribs 41 and the second ribs 43 are continuous with the lower surface side outer peripheral ribs 23 even when the adjacent pallets 1 are close to each other. Is formed. Therefore, the lower surface side outer peripheral rib 23 of one pallet 1 can be prevented from riding on the lower surface side outer peripheral rib 23 of the other pallet 1.

  Further, as shown in FIG. 5, when the pallet 1 is lifted and transported by a transporting machine such as a forklift or a handlift, and placed close to the pallet 1 already placed, it is displaced in the height direction. Thus, the upper surface side outer peripheral rib 15 and the lower surface side outer peripheral rib 23 may enter the first gap portion 42 between the first ribs 41 by mistake. In this case, the upper surface side outer peripheral rib 15 and the lower surface side outer peripheral rib 23 that have entered can be smoothly removed following the taper portion 40a of the first rib 41 located immediately below.

  Further, unlike the second rib 43, the first rib 41 is not continuously formed between the upper surface side outer peripheral rib 15 and the lower surface side outer peripheral rib 23, and the first gap portion 42 is interposed therebetween. The strength is lower than that of the second rib 43, and it is easy to break. However, as shown in FIG. 6, since the second rib 43 is formed near the first rib 41, the obstacle 90 hits the second rib 43 before hitting the first rib 41. Therefore, it can prevent that the 1st rib 41 which prevents the shift | offset | difference of the stretch film 50 is damaged.

According to the above embodiment, the following effects can be obtained.
(1) When the stretch film 50 is wound around the pallet 1, the portion of the first rib 41 becomes an inflection point. Therefore, the stretch film 50 is reliably wound around the pallet 1 by the automatic winding machine. Furthermore, since the lower corner portion 40 of the first rib 41 is formed in a shape close to a right angle, the stretch film 50 is securely locked, and the stretch film 50 is displaced and loosened, for example, so that the load collapses. Occurrence can be suppressed. That is, the pallet 1 can prevent the stretch film 50 from being displaced with a simple configuration in which the first gap portion 42 is simply provided in the first rib 41 formed separately from the second rib 43.

  (2) The first gap portion 42 is wider than the thickness of the upper surface side outer peripheral rib 15 and the lower surface side outer peripheral rib 23. And the upper surface side of the 1st rib 41 becomes the taper part 40a which inclines toward the outer side from an upper surface side to a lower surface side. Therefore, the upper surface side outer peripheral rib 15 and the lower surface side outer peripheral rib 23 that have entered the first gap portion 42 are easily detached from the first gap portion 42.

  (3) In addition to the upper surface side outer peripheral rib 15 and the lower surface side outer peripheral rib 23, each corner beam 31 is provided with the first rib 41, and further, the second rib 43 is provided on both sides of the first rib 41, Strength can be increased.

  (4) The lower surface side outer peripheral rib 23 and the first rib 41 are continuously formed, and no step is formed in which the lower surface side outer peripheral rib 23 projects from the first rib 41. Therefore, also in this respect, it is possible to suppress the lower surface side outer peripheral rib 23 of one pallet 1 from riding on the lower surface side outer peripheral rib 23 of the other pallet 1.

  (5) Since the second rib 43 is formed near the first rib 41, the obstacle 90 hits the second rib 43 before hitting the first rib 41. Therefore, it can prevent that the 1st rib 41 which prevents the shift | offset | difference of the stretch film 50 is damaged.

In addition, the said embodiment can also be suitably changed and implemented as follows.
-As shown in FIG. 7, you may make it provide the 1st clearance gap part 42 formed between the 1st ribs 41 more than the example of Fig.3 (a). Here, five first gap portions 42 are provided at equal intervals. As a result, the stretch film 50 wound up on the pallet 1 has many inflection points formed by the first ribs 41 and also has many corners 40 on the lower surface side of the first ribs 41. Thereby, the stretch film 50 will be more reliably latched by the 1st rib 41, and it is suppressed that it slips | deviates with respect to the outer surface part 13 of the pallet 1, and can suppress generation | occurrence | production of load collapse. . The numbers of the first ribs 41 and the first gap portions 42 are not particularly limited. Further, the first gap portions 42 may be formed at irregular intervals or irregularly.

  Also in the above case, the first gap portion 42 is made wider than the thickness of the outer peripheral ribs 15 and 23. Further, among the plurality of first ribs 41, the lowermost first rib 41a can be provided continuously with the lower surface side outer peripheral rib 23, and the strength can be made higher than when a gap is provided therebetween.

  As shown in FIG. 8, the second rib 43 may be provided intermittently like the first rib 41, and the second gap portion 44 may be provided between the second ribs 43. As a result, the stretch film 50 has an inflection point formed in the second rib 43 portion in addition to the corner portion 40 of the first rib 41, and is further locked to the corner portion 45 on the lower surface side. Misalignment is prevented. Further, a tapered portion 45 a similar to the tapered portion 40 a may be formed on the upper surface side of the second rib 43. Even when the second gap portion 44 is provided in the second rib 43, the second gap portion 44 is made wider than the thickness of the outer peripheral ribs 15, 23, so that the same as the first rib 41 and the first gap portion 42. An effect can be obtained. In addition, the height from the ground contact surface 22 where the first gap portion 42 and the second gap portion 44 are formed may be aligned as shown in FIG. 9 or may not be aligned at different heights. .

  FIG. 9 shows the bonding pallet 60. The bonding pallet 60 is a single-sided pallet, and is configured by abutting and joining an upper surface side pallet forming member 61 and a lower surface side pallet forming member 71. The upper surface side pallet forming member 61 includes an upper surface deck board 62 having substantially the same configuration as the upper surface deck board 11 and an upper surface side corner beam half 63 constituting the corner beam portion 81. Further, the lower surface side pallet forming member 71 includes a lower surface deck board 72 having substantially the same configuration as the upper surface deck board 62 and a lower surface side corner beam half 73 constituting the corner beam portion 81.

  The upper surface side pallet forming member 61 and the lower surface side pallet forming member 71 are configured by joining the upper surface side girder half 63 and the lower surface side girder half 73 by butting and welding. In the corner girder portion 81 of the bonded pallet 60 configured as described above, a joint portion 82 that becomes a joint line between the upper surface side pallet forming member 61 and the lower surface side pallet forming member 71 in the middle in the thickness direction. Is formed. In the corner beam 81, a plurality of first ribs 83 are formed on the outer side surface 81a so as to extend linearly in the thickness direction. A first gap 84 is formed between the two first ribs 83 adjacent to each other and between the upper surface side outer peripheral rib and the upper surface side first rib 83. Note that the functions of the first rib 83 and the first gap portion 84 are the same as those of the first rib 41 and the first gap portion 42 described above, and therefore the details are omitted.

  The first rib 83 may be located at the joint portion 82, but here, the first gap portion 84 a located in the middle of the thickness direction is located at the joint portion 82, and the end faces of the first rib 83 are Is not welded. Thereby, it is possible to prevent the first rib 83 from being formed with a burr or the like formed at the joint portion 82. That is, the first rib 83 can be prevented from being deformed during welding. In addition, the second ribs 43 are also formed at the positions of the joints 82 with respect to the second ribs 43 to obtain the same effects as the first ribs 83 and the first gaps 84. Further, a tapered portion 83a similar to the tapered portion 40a is formed at the upper surface side corner of the first rib 83.

  In the single-sided bonding pallet 60 shown in FIG. 9, the shapes of the upper surface side pallet forming member 61 and the lower surface side pallet forming member 71 are different. Therefore, the mold for molding the upper surface side pallet forming member 61 and the mold for molding the lower surface side pallet forming member 71 are different. Therefore, the first gap portion 84 can be formed only on the first rib 83 of the upper surface side pallet forming member 61.

It should be noted that this bonding pallet 60 can also be implemented with appropriate modifications as follows.
FIG. 10 is a double-sided bonding pallet. In this pallet, the shapes of the upper surface side pallet forming member 61 and the lower surface side pallet forming member 71 are substantially the same. Accordingly, substantially the same mold is used for the upper surface side pallet forming member 61 and the lower surface side pallet forming member 71. Therefore, as shown in FIG. 10, the first rib 83 and the first gap portion 84 having substantially the same configuration are formed on the upper surface side pallet forming member 61 and the lower surface side pallet forming member 71.

-As shown in FIG. 7, you may make it provide more 1st gap | interval parts 84 formed between the 1st ribs 83 than the example of FIG.
As shown in FIG. 8, the second rib 43 may also be provided intermittently like the first rib 83, and the second gap portion 44 may be provided between the second ribs 43. Further, the second rib 43 may also be formed with a tapered portion 45a at the upper side corner portion. Moreover, you may form a lower surface side corner | angular part so that the shape close | similar to a right angle may be made.

The pallets 1 and 60 can be implemented with appropriate modifications as follows.
The pallets 1 and 60 may omit the second rib 43 as long as at least the first rib 41 and the first rib 83 are provided.
The first gap 41 and the first rib 83 may also form the first gap portions 42 and 84 between the lower surface side outer peripheral rib 23.
As shown in FIG. 11, not only one pallet 1 and 60 is provided in a straight line, but a plurality of pallets may be formed. Here, two first ribs 41 are formed in parallel. The more first ribs 41 are provided, the more the inflection points of the stretch film 50 are increased, and the stretch film 50 can be wound around the pallets 1 and 60 further.

  -The taper part 40a, 45a, 83a formed in the upper side or the lower side of the 1st rib 41, 83 and the 2nd rib 43 does not need to be formed. In this case, the upper or lower end portions of the first ribs 41 and 83 and the second ribs 43 are formed in a shape close to a right angle.

  As shown in FIG. 12, the length (G) of the first gap portion 42 may be narrower than the thickness (T) of the upper surface side outer peripheral rib 15 and the lower surface side outer peripheral rib 23. Accordingly, it is possible to prevent the upper surface side outer peripheral rib 15 and the lower surface side outer peripheral rib 23 from being caught in the first gap portion 42 when the pallet 1 is transported. In this case, the tapered portion 40a formed when the length (G) of the first gap portion 42 is wider than the thickness (T) of the upper surface side outer peripheral rib 15 and the lower surface side outer peripheral rib 23 can be eliminated. This also applies to the bonding pallet 60.

The first rib 41 and the first rib 83 may be provided on the outer surface of the intermediate beam portion 32. The second rib 43 may also be provided on the outer surface of the intermediate beam part 32.
The first ribs 41 and 83 and the second ribs 43 may be formed obliquely rather than perpendicular to the upper surface side outer peripheral rib 15 and the lower surface side outer peripheral rib 23.

The first ribs 41 and 83 may be formed so as to be continuous with the upper surface side outer peripheral rib 15. That is, the first gap portions 42 and 84 may not be formed between the first ribs 41 and 83 and the upper surface side outer peripheral rib 15. Thereby, intensity | strength can be raised further.
The shape of the first ribs 41 and 83 is not limited to a long plate shape. For example, the first ribs 41 and 83 may be formed by intermittently arranging columns such as columns, prisms, and truncated cones in a straight line, or randomly arranged.
The heights of the first ribs 41 and 83 are not necessarily aligned with the heights of the upper surface side outer peripheral ribs 15 and the lower surface side outer peripheral ribs 23 and are higher than the heights of the upper surface side outer peripheral ribs 15 and the lower surface side outer peripheral ribs 23. Or low. The heights of the first ribs 41 and 83 and the second ribs 43 may be different. Further, the second ribs 43 may not be aligned with the heights of the upper surface side outer peripheral ribs 15 and the lower surface side outer peripheral ribs 23.

  Even if the pallets 1 and 60 have a rectangular shape, the ratio of the long side to the short side is not limited to that shown in FIGS. Further, the pallet 1 is not limited to a rectangular shape, and may be a triangular shape or a pentagon or more polygon. Moreover, other squares, such as trapezoid shape and a rhombus shape, may be sufficient. Further, it may be circular or elliptical.

The pallets 1 and 60 may be a two-way pallet instead of a four-way pallet. Furthermore, the pallet 1 may be a single-sided use pallet as well as an integrally-molded double-sided use pallet. In addition, the integrally molded pallet may be a single-sided skid type. Furthermore, although it is a four-way pallet, it may be a quasi-four-way pallet that can be handled only in two directions by a pallet truck.
The pallets 1 and 60 may be made of metal or wood, and the material is not particularly limited.
