Description

  The present invention relates to a pallet and a grommet.

  In pallets used for transportation and storage of articles, those made of synthetic resin are frequently used. A synthetic resin pallet is excellent in terms of light weight, durability, water absorption resistance, and contamination resistance, and has a feature that the surface is slippery. Therefore, grommets are attached as anti-slip members to the loading surface of the pallet and the surface facing the fork insertion hole into which the fork is inserted. Specifically, the grommet is attached to a concave portion provided on the loading surface of the pallet or the surface facing the fork insertion hole so as to be exposed on the surface (for example, see Patent Document 1).

Japanese Patent Laid-Open No. 10-77037

  By the way, although the pallet described in Patent Document 1 is washed with washing water after use, the washing water may remain in the concave portion to which the grommets of the pallet are attached during washing. In Patent Document 1, a grommet is fitted in a recess to which the grommet is attached. Therefore, the cleaning water that has entered from between the grommet and the peripheral wall of the recess accumulates in the recess, and as a result, the drying time for drying the pallet becomes longer.

  This invention is made | formed in view of such a situation, The objective is to provide the grommet used for the pallet and pallet which made it possible to shorten the drying time after washing | cleaning.

  A pallet that solves the above problem is a pallet in which a grommet is attached to a through-hole penetrating a deck board up and down, and the grommet projects outwardly from a trunk portion located in the through-hole and an upper portion of the trunk portion. An upper diameter-enlarged portion provided with an upper collar portion, comprising a thin portion in which a part of the outer peripheral portion is cut away from the inner surface of the upper collar portion toward the outer surface, and the outer surface side of the upper collar portion remains. A lower diameter-increased portion including the upper diameter-expanded portion, a lower collar portion projecting outward from a lower portion of the body portion, and a lower notch portion that is cut through the lower collar portion in the vertical direction, The through hole is provided on the loading surface side of the deck board, and supports an upper support portion that supports the upper enlarged diameter portion, a through portion that is continuous with the upper support portion, and the trunk portion is located, and the lower enlarged portion. Is inserted into the through-hole from the upper support part side And a engaging portion for the inner surface engaging the lower enlarged diameter portion of the grommet.

  According to the above configuration, when cleaning the pallet, the cleaning liquid may enter from the gap between the grommet and the peripheral wall of the through hole, and the cleaning liquid may accumulate in the through hole. In this respect, the upper diameter-enlarged portion of the grommet is a thin-walled portion and airtightness is lowered. Therefore, the cleaning liquid accumulated in the through hole is likely to come out from the lower notch, and as a result, the drying time after cleaning the pallet can be shortened.

About the said pallet, it is preferable that the said trunk | drum is diameter-reduced as it goes to the lower part from an upper part, and the said lower diameter enlarged part is a smaller diameter than the said upper diameter enlarged part.
According to the said structure, it becomes easy to insert in a through-hole by making the lower diameter enlarged part of a grommet into an insertion end.

About the said pallet, it is preferable that the surrounding wall of the said through-hole is a perpendicular | vertical surface with respect to the above-mentioned load surface, and the space part is comprised between the outer peripheral surface of the said trunk | drum, and the said surrounding wall.
According to the said structure, the dispersion | variation in shaping | molding of a pallet can be absorbed and a grommet can be reliably attached to a through-hole.

About the said pallet, it is preferable that the said thin part and the said lower notch part are provided in the same position in the circulation direction of the said trunk | drum.
According to the above configuration, the cleaning liquid that has entered from the thin portion is easily discharged from the lower notch as it is.

  A grommet that solves the above problem is a grommet that is attached to a through hole that vertically penetrates a deck board of a pallet, and includes a trunk portion that is located in the through hole, and an upper collar that projects outward from the upper portion of the trunk portion. An upper diameter-enlarging portion provided with a portion, wherein the upper enlarged portion is provided with a thin portion in which a part of the outer peripheral portion is notched in the direction from the inner surface to the outer surface of the upper collar portion and the outer surface side of the upper collar portion remains.

Hereinafter, an embodiment of a pallet and a grommet will be described with reference to FIGS. The pallet is a four-sided single-sided pallet.
As shown in FIGS. 1 and 2, the pallet 1 includes an upper pallet forming member 2 and a lower pallet forming member 3. The upper pallet forming member 2 and the lower pallet forming member 3 are welded to each other.

  The upper pallet forming member 2 includes a deck board 20 having a rectangular plate shape and an upper girder 21 extending from the deck board 20 toward the lower pallet forming member 3. The deck board 20 is formed with a plurality of through holes 24 penetrating from the loading surface 22 which is the outer surface of the deck board 20 to the girder forming surface 23 which is the opposite surface of the deck board 20 to the loading surface 22. Yes. The upper pallet forming member 2 is molded such that the inside is hollow by a gas assist molding method using, for example, polypropylene.

  Four through holes 24 are formed on each of the two diagonal lines of the deck board 20. A grommet 10 for preventing the pallet 1 from sliding relative to the fork of a forklift or a pallet truck is fitted in each of the plurality of through holes 24.

  Three anti-skid tapes 25 are welded to the loading surface 22 of the deck board 20 in order to prevent the load placed on the loading surface 22 from sliding relative to the loading surface 22. Each of the three anti-slip tapes 25 has a linear shape extending along one side of the loading surface 22. Each of the three anti-slip tapes 25 has a length covering almost the entire length of one side of the loading surface 22 from the right edge of the loading surface 22 to the left edge of the loading surface 22. Each of the three anti-slip tapes 25 is arranged along a direction orthogonal to the extending direction, which is the direction in which the anti-slip tape 25 extends.

  The lower pallet forming member 3 includes a grounding board 30 having a rectangular plate shape and a lower girder 31 having a cylindrical shape extending from the grounding board 30 toward the upper pallet forming member 2. The pallet 1 is configured by welding the lower end of the upper beam 21 and the upper end of the lower beam 31 facing the upper beam 21. Similar to the upper pallet forming member 2, the lower pallet forming member 3 is formed by, for example, a gas assist molding method using polypropylene.

  A total of eight fork insertion holes 4 are provided on the peripheral surface of the pallet 1, one between each of the central girders and the double-sided girders. That is, two fork insertion holes 4 are provided on each side. The fork insertion holes 4 provided on the opposite sides communicate with each other and are insertion passages into which forks of a forklift or a pallet truck are inserted. The through hole 24 into which the grommet 10 is fitted is provided so as to face the insertion passage formed by the fork insertion hole 4.

  As shown in FIGS. 3 and 4, the grommet 10 includes a trunk portion 11 located in the through-hole 24, an upper diameter-enlarged portion 12 configured by projecting an upper portion of the trunk portion 11 outward, and a lower portion of the trunk portion 11. And a lower-diameter enlarged portion 14 configured to project outward.

  The trunk | drum 11 has a truncated cone shape, and has the shape diameter-reduced so that it went to the lower part from the upper part. That is, the outer diameter D11 of the lower end portion of the trunk portion 11 is smaller than the outer diameter D10 of the upper end portion of the trunk portion 11 (D11 <D10) (see FIG. 5), and the through portion 41 constituting the through hole 24 is formed. A gap W is formed between the side walls.

  The upper diameter-enlarged portion 12 includes an upper portion of the trunk portion 11 and an upper collar portion 12 </ b> A projecting outside the upper portion of the trunk portion 11. Further, the upper diameter-enlarged portion 12 includes a thin-walled portion 13 in which a part of the outer peripheral portion is notched in the direction from the inner surface (lower surface) of the upper collar portion 12A to the outer surface (upper surface), and the outer surface side of the upper collar portion 12A is left. I have. The upper diameter-enlarged portion 12 is larger in diameter than the body portion 11. The outer diameter D12 of the upper enlarged portion 12 is larger than the outer diameter D10 of the upper portion of the trunk portion 11 (D12> D10) (see FIG. 5) and is locked to the upper support portion 42 of the through hole 24. I am doing so.

  The thin portion 13 faces the outer surface (upper surface) of the upper enlarged diameter portion 12 and constitutes a part of the upper surface. Further, on the back side of the thin portion 13, a not-through portion 13 </ b> A that is non-penetrating in the thickness direction is formed on the outer peripheral portion and the inner surface (lower surface) of the upper flange portion 12 </ b> A. For this reason, when viewed from the loading surface 22 side of the pallet 1, the notch 13 </ b> A located on the back side of the thin portion 13 of the upper diameter-expanded portion 12 is not visible, so that deterioration of the design can be suppressed. Here, the shape of the cutout portion 13A has a rectangular cutout shape. The shape of the notch 13A is not particularly limited, and may be a V shape. Further, the cutout portion 13 </ b> A can be not only the upper collar portion 12 </ b> A protruding from the trunk portion 11, but also a cutout portion that extends into the trunk portion 11.

  The lower diameter enlarged portion 14 includes a lower portion of the trunk portion 11 and a lower collar portion 14 </ b> A projecting outside the lower portion of the trunk portion 11. Further, the lower diameter enlarged portion 14 includes a lower notch portion 15 that is cut through the lower collar portion 14A vertically. The lower diameter expanded portion 14 is larger in diameter than the body portion 11. The outer diameter D14 of the lower enlarged portion 14 is larger than the outer diameter D11 of the lower portion of the trunk portion 11 (D14> D11) (see FIG. 5). It engages with the joint portion 43. The lower collar portion 14A is a portion where the inner surface (upper surface 14B) engages with the engaging portion 43 protruding from the through portion 41, and includes a flat surface perpendicular to the central axis extending in the vertical direction of the body portion 11. Yes. Further, the outer surface (lower surface) of the lower collar portion 14A has an outer peripheral portion that is a tapered surface, which makes it easier to get over the engaging portion 43. The outer diameter D14 of the lower enlarged portion 14 is smaller than the outer diameter D12 of the upper enlarged portion 12 (D14 <D12) (see FIG. 5), and is easily inserted into the penetration portion 41.

  The lower notch 15 is a portion that serves as a drain for the cleaning water accumulated in the gap W. The lower notch portion 15 has a rectangular notch shape with respect to the lower collar portion 14A. In addition, the shape of the lower notch part 15 is not specifically limited, V shape etc. may be sufficient. Further, the lower notch 15 may be a notch that extends into the body 11 as well as the lower collar portion 14 </ b> A that protrudes from the body 11.

  The thin portion 13 and the lower notch portion 15 are provided at the same position in the circumferential direction of the body portion 11. Further, the opening width L13 of the thin portion 13 in the circumferential direction of the upper enlarged diameter portion 12 is longer than the opening width L15 of the lower notch portion 15 in the circumferential direction of the lower enlarged diameter portion 14 (L13> L15). Unlike the lower notch 15, the thin portion 13 is non-penetrating, and is therefore wider than the lower notch 15 in order to reduce airtightness.

  As shown in FIG. 5, the grommet 10 configured as described above is inserted into the through hole 24 from the loading surface 22 with the lower diameter enlarged portion 14 as an insertion end into the through hole 24. The through hole 24 is associated with the upper support portion 42 provided on the loading surface 22 side of the deck board 20, the through portion 41 continuing to the upper support portion 42, and the inner surface (upper surface 14 </ b> B) of the lower diameter enlarged portion 14 of the grommet 10. And an engaging portion 43 to be joined.

  The upper support portion 42 is a recess into which the upper diameter-enlarged portion 12 is fitted, and includes a support surface that supports the upper diameter-enlarged portion 12 from the back surface (lower surface 12B) side and side walls around the support surface. The support surface is the bottom surface of the recess, and the penetrating portion 41 is located at the center of the bottom surface. The diameter D42 of the upper support part 42 is larger than the diameter D41 of the through part 41 where the body part 11 of the grommet 10 is located (D42> D41), and the upper enlarged diameter part 12 becomes the upper support part 42. It is intended to be supported. The outer diameter D12 of the upper enlarged portion 12 of the grommet 10 is slightly smaller than the diameter D42 of the upper support portion 42 (D12 <D42), and there is a minute gap between the upper enlarged portion 12 and the upper support portion 42. To be formed. Further, the height H12 of the upper enlarged portion 12 is slightly shorter than the depth L42 of the upper support portion 42 (H12> L42), so that the upper enlarged portion 12 does not protrude from the upper support portion 42.

  The trunk portion 11 of the grommet 10 inserted into the through hole 24 is located in the through portion 41. The peripheral wall of the penetrating portion 41 is a vertical surface with respect to the loading surface 22. A gap W is formed as a space between the outer peripheral surface of the trunk portion 11 and the peripheral wall of the penetrating portion 41.

  The engaging portion 43 engages with the inner surface (upper surface 14B) of the lower diameter expanding portion 14 of the grommet 10 inserted into the through hole 24 from the upper support portion 42 side, with the lower diameter increasing portion 14 as an insertion end. The upper surface of the engaging portion 43 is configured as an insertion guide surface that is inclined inward and downward. Further, the lower surface of the engaging portion 43 is an engaging surface perpendicular to the peripheral wall of the penetrating portion 41 that contacts the inner surface (upper surface 14B) of the lower collar portion 14A. Since the upper surface of the engaging portion 43 is inclined, when the grommet 10 is inserted into the through hole 24 from above, at least one of the lower collar portion 14A and the engaging portion 43 is bent and the lower diameter enlarged portion 14 is formed. The upper surface 14B of the lower diameter enlarged portion 14 is engaged with the engaging portion 43. The diameter D43 of the front end portion of the engaging portion 43 is shorter than the diameter D41 of the penetrating portion 41 (D43 <D41), and protrudes to the inside of the penetrating portion 41. The outer diameter D14 of the lower enlarged portion 14 of the grommet 10 is slightly smaller than the diameter D41 of the penetrating portion 41 (D14 <D41), and larger than the diameter D43 of the distal end portion of the engaging portion 43 (D14). > D43), the lower diameter enlarged portion 14 can be inserted into the penetrating portion 41 and engaged with the engaging portion 43.

  The upper diameter-enlarged portion 12 is fitted into the upper support portion 42 and the lower-diameter enlarged portion 14 is engaged with the engaging portion 43, whereby the grommet 10 is positioned with respect to the vertical direction of the through hole 24. In the grommet 10, the upper enlarged portion 12 does not protrude from the loading surface 22 of the pallet 1, and the lower enlarged portion 14 protrudes from the girder forming surface 23.

Next, the operation of the pallet 1 and the grommet 10 will be described.
When a fork such as a forklift is inserted into the fork insertion hole 4 of the pallet 1 to which the grommet 10 is attached and the fork is lifted, the fork and the lower enlarged portion 14 of the grommet 10 come into contact with each other and the pallet 1 slides against the fork. This can be suppressed. Since the upper diameter-expanded portion 12 of the grommet 10 does not protrude from the loading surface 22, it is possible to prevent a depression or the like from being formed on the load.

  When the pallet 1 to which the grommet 10 is attached is cleaned with a cleaning liquid such as water, the cleaning liquid enters the gap W between the body portion 11 of the grommet 10 and the through portion 41 of the through hole 24. That is, the cleaning liquid enters the inside through a minute gap between the outer peripheral portion of the upper enlarged diameter portion 12 and the side wall of the upper support portion 42 in the grommet 10, and the cleaning liquid accumulates in the gap W between the body portion 11 and the through portion 41. In this respect, in the upper support portion 42, the thin-wall portion 13 has a reduced contact area with the side wall of the upper support portion 42, and the airtightness is reduced accordingly. The thin-walled portion 13 is a portion where the cleaning liquid easily enters inside, but also functions as an air communication portion that is easy to communicate with the external space. Therefore, the cleaning liquid that has entered the gap W can be easily discharged from the lower notch 15, and the evaporation of the cleaning liquid can be promoted. The cleaning water that has entered the gap W is configured by an inclined surface that is reduced in diameter by the outer peripheral surface of the body portion 11 being hung from the upper part to the lower part. Therefore, at least a part of the cleaning water in the gap W is drained from the lower notch 15 located at the lower part along the outer peripheral surface of the body 11.

As described above, according to this embodiment, the following effects can be obtained.
(1) When cleaning the pallet 1, the cleaning liquid may enter through the gap W between the grommet 10 and the peripheral wall of the through hole 24, and the cleaning liquid may accumulate in the through hole 24. In this respect, the upper diameter-enlarged portion 12 of the grommet 10 has a thin-walled portion 13 and the airtightness is lowered. Therefore, the cleaning liquid accumulated in the through-hole 24 can easily come out from the lower notch 15, and as a result, the drying time after cleaning the pallet 1 can be shortened.

  (2) Since the diameter of the body 11 of the grommet 10 decreases from the upper part toward the lower part and the outer diameter D14 of the lower enlarged part 14 is shorter than the outer diameter D12 of the upper enlarged part 12, the grommet 10 is Easy to insert into the through hole 24.

  (3) Since the body 11 and the gap W are small enough to be formed with respect to the through-hole 41, even if the size and shape of the grommet 10 vary, the gap W can absorb the variation, and the through-hole The grommet 10 can be securely attached to 24.

  (4) Since the thin part 13 and the lower notch part 15 are provided at the same position in the circumferential direction of the body part 11, the cleaning liquid that has entered from the thin part 13 of the grommet 10 falls in the vertical direction as it is. It becomes easy to discharge from the lower notch 15.

In addition, the said embodiment can also be implemented with the following forms which changed this suitably.
In the above configuration, the position and number of the through holes 24 can be arbitrarily set. Further, whether or not the grommet 10 is attached to the through hole 24 can be arbitrarily set. That is, the grommets 10 may not be attached to all the through holes 24.

-Although the thin part 13 and the lower notch part 15 were provided in the same position in the circumferential direction of the trunk | drum 11, you may provide the thin part 13 and the lower notch part 15 in a different position in the circumferential direction of the trunk | drum 11.
In the above embodiment, the peripheral wall of the penetration part 41 is a vertical surface with respect to the loading surface 22, but the peripheral wall of the penetration part 41 may be inclined with respect to the loading surface 22. That is, the size and shape of the gap W are not limited to the example of FIG.

  -In above-mentioned embodiment, although the trunk | drum 11 of the grommet 10 was made into the truncated cone shape diameter-reduced so that it went to the lower part from the upper part, the trunk | drum 11 of the grommet 10 is a cylindrical shape with the same upper and lower diameter, or upper and lower parts. It is good also as a barrel shape which the diameter was the same and the diameter of the intermediate part was enlarged. Further, as an example, the outer diameter D11 of the lower end portion of the trunk portion 11 is larger than the outer diameter D10 of the upper end portion of the trunk portion 11 (D11> D10), and increases in diameter from the upper portion toward the lower portion. It is good.

  In the above embodiment, the outer diameter D14 of the lower enlarged portion 14 of the grommet 10 is smaller than the outer diameter D12 of the upper enlarged portion 12 (D14 <D12), but the lower enlarged portion 14 of the grommet 10 The outer diameter D14 may be larger than the outer diameter D12 of the upper enlarged portion 12 (D14> D12).

  In the above embodiment, the upper surface of the lower diameter expanded portion 14 of the grommet 10 is engaged with the engaging portion 43 of the through hole 24, but the engaging portion 43 is omitted and the inner surface (upper surface 14 </ b> B) of the lower diameter expanded portion 14. ) May contact the beam forming surface 23 of the pallet 1. That is, the outer diameter D14 of the lower enlarged portion 14 of the grommet 10 may be larger than the inner diameter D41 of the penetrating portion 41 (D14> D41).

  In the above embodiment, the opening width L13 of the thin portion 13 is longer than the opening width L15 of the lower notch portion 15 (L13> L15). However, the opening width L13 of the thin portion 13 and the opening width L15 of the lower notch portion 15 may be the same (L13 = L15), or the opening width L13 of the thin portion 13 is shorter than the opening width L15 of the lower notch portion 15. (L13 <L15).

In the above-described embodiment, the columnar grommet 10 including the truncated cone shape is used. However, a cylindrical grommet 10 having a through hole in the center may be used.
In the above embodiment, the number of thin portions 13 and the number of lower notches 15 are the same, but the number of thin portions 13 and the number of lower notches 15 may be different. Further, a plurality of thin portions 13 and lower notches 15 may be provided.

  In the above embodiment, the grommet 10 protrudes below the girder forming surface 23 so as to contact the fork, but the grommet 10 is above the loading surface 22 so as to contact the load on the loading surface 22 of the pallet 1. May protrude. Thereby, it can suppress that a load slides with respect to the loading surface 22. FIG. Further, the grommet 10 may protrude below the girder forming surface 23 and may protrude above the loading surface 22.

  In the above configuration, the pallet 1 may be a double-sided pallet in which both sides are set as loading surfaces in a four-way pallet, or a single-sided or double-sided pallet.
