Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a synthetic resin pallet suitable for carrying and loading bags.
[0002]
[Prior art]
The synthetic resin pallet shown in Patent Document 1 below has an outer wall that is higher than the top surface of the deck board on the outer periphery in order to prevent rainwater and the like from penetrating from the side surface of the pallet to the top surface of the deck board when stacked. And a groove was formed on the inside. In addition, this synthetic resin pallet was provided with a through hole for draining substantially the entire mounting surface.
Moreover, the pallet shown by the following patent document 2 formed many slit-shaped through-holes in the part corresponded to the through-hole for fork insertion of a mounting surface.

[Problems to be solved by the invention]
By the way, the pallet is used to carry various articles. For example, a cylindrical synthetic resin bag (flexible container) such as a plastic bag containing granular materials such as resin pellets, powder, liquid, etc. ), But when a bag containing such a fluid is placed, the fabric of the portion of the bottom of the bag that hits the through hole sinks into the through hole, leaving a mark. There was a risk of damage. Also, on a pallet with a flat mounting surface, rainwater enters the gap between the mounting surface and the bottom of the bag due to capillarity, making it difficult for water to escape. There was a drawback that it easily adheres.
[0005]
Therefore, the present invention is intended to provide a synthetic resin pallet for carrying a bag, which can be placed without damaging the bottom of the bag, easily drains water, and has strength enough to withstand heavy bags.
[0006]
[Means for Solving the Problems]
For this purpose, the synthetic resin pallet for bag loading according to the present invention connects a pair of deck boards formed integrally with a girder half and reinforcing grid ribs on the back side by connecting the end faces of the girder half. A synthetic resin pallet in which a through hole for fork insertion is formed between both deck boards, and a portion of the mounting surface of the deck board corresponding to the portion in which the through hole is formed A large number of partitioned drain holes are formed in a substantially arc-shaped range centering on the center of the mounting surface of the deck board.
For this reason, most of the bottom surface of the bag is loaded so as to be in contact with a flat mounting surface corresponding to the half of the girder, the bag is not damaged, and rain water intrusion due to capillary action can be prevented.
[0007]
Further, the present invention is characterized in that in the pallet, the drain hole is a rectangular shape partitioned by lattice ribs.
Such a rectangular drainage hole is square, so that capillary action is less likely to occur, and the opening area can be maximized, so that the drainage action is more reliably performed. Moreover, since the continuity of the reinforcing grid-like ribs is not inhibited, the strength can be provided to withstand heavy bags.

DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an external perspective view of the pallet, FIG. 2 is a plan view thereof, and FIG. 3 is a perspective view of the back surface of the synthetic resin deck board constituting the pallet. As shown in FIG. 3, the deck board 1 having a rectangular shape in this embodiment has girder halves 2 and 2 and a girder half 3 integrally formed on both long sides and the center of the back surface. Reinforcing grid ribs 4 are integrally formed in the half halves 2 and 2 and the girder half 3, and the gaps 5 and 5 between the girder half 2 and 2 and the girder half 3 are spaced from the grid rib 4. However, by making the mesh finer, reinforcing grid-like ribs 6 that are thinner than the inside of the girder half but can have strength are integrally formed. The intervals 5 and 5 can be through holes for fork insertion, and 7 is a rubber grommet secured to the back surface of the deck board 1 for preventing slipping. The pair of deck boards 1 and 1 are connected to each other by means of heat welding or the like, as shown in FIGS. , 1 fork insertion holes 8, 8 are formed in parallel, and a pair of fork insertion ports 9, 9 are opened on the short side.
[0009]
Further, a rectangular water drain hole 10 of about 40 mm square defined by the lattice rib 6 is formed in a part of the mounting surface of the deck board 1, 1 corresponding to the portion where the through holes 8, 8 are formed. A large number of arcs are formed in an approximately arc-shaped range centered on the center 11 of the mounting surface of the board 1 with an interval of about 20 mm. Further, the entire mounting surface of the deck board 1, 1 corresponding to the portion where the through-holes 8, 8 are formed is a small round hole 12 having a diameter of about 15 mm, one by one in an area partitioned by the grid-like ribs 6. Will be established. In addition, 13 is a small hole having a diameter of about 10 mm in which a plurality of lines are arranged in parallel on the mounting surface of the deck board 1, 1 corresponding to the fork insertion ports 9, 9, and 14 is for preventing the load from slipping. A rubber grommet fastened to the surface of the deck board 1.
[0010]
Further, the mounting surface of the deck board 1 corresponding to the girder half 3 is not formed with any through hole such as the drain hole or the round hole, and both slit-like grooves 15 having both ends communicating with the drain hole 10 are formed. It is formed in a transverse shape near the short side. (See FIG. 5).
[0011]
As shown in FIG. 4, the synthetic resin pallet configured as described above is in contact with the placement surface of the pallet when a cylindrical synthetic resin bag 20 containing powder, liquid, or the like is loaded. The outer diameter of the bottom portion of the bag is adjusted so that the contact range of the bottom portion of the bag is almost over the drain hole 10. By doing so, the bottom of the bag is supported on the flat placement surface at the center of the deck board 1 corresponding to the half of the girder 3, so that the bag can be loaded without damaging the bottom. Further, since rainwater that has poured into the bag falls out of the drainage hole 10 located outside the bag into the through holes 8 and 8, it is possible to prevent rainwater from entering the gap between the bottom of the bag and the mounting surface as in the prior art.
[0012]
Moreover, the slit-like groove 15 formed in a transverse shape on the mounting surface on the girder half 3 guides rainwater to the drain holes 10 at both ends, thereby preventing rainwater from entering from this direction.
[0013]
【The invention's effect】
Thus, the synthetic resin pallet for bag loading according to the present invention connects a pair of deck boards, in which the half of the spar and the reinforcing grid-like rib are integrally formed on the back side, to the end surfaces of the spar half. Thus, a synthetic resin pallet in which through holes for fork insertion are formed between both deck boards, wherein the lattice-like shape is formed on a part of the mounting surface of the deck board corresponding to the part in which the through holes are formed. Since a plurality of drain holes defined by ribs are formed in a substantially arc-shaped range centered on the center of the deck board mounting surface, a bottom fabric of the bag can be obtained by loading a bag having an outer diameter matching the drain hole. The rainwater will surely fall out from the drainage hole that is opened sufficiently large at the required position without damaging the bag, so that the rainwater will not enter the bottom of the bag and dirt and dust will not easily adhere.
