DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows an appearance of a cargo handling pallet according to the present invention.
[0018]
The cargo handling pallet 10 is made of paper made of cardboard or the like, and includes a top plate 11, a bottom plate 12, and a plurality of blocks 13 that maintain a distance therebetween.
[0019]
The top plate 11 is formed by overlapping a paper rectangular upper sheet 15 and a lower sheet 16. The bottom plate 12 is formed by superposing a paper rectangular upper sheet 17 and a lower sheet 18 having the same size as the top plate 11, and a rectangular escape hole 20 having the same size as shown in FIG. In the example shown, four are arranged vertically and horizontally. Then, nine blocks 13 having the same height are arranged on the bottom plate 12 in the same manner in the vertical and horizontal directions, avoiding the escape holes 20.
[0020]
In the bottom plate 12, the upper sheet 17 above the stacked sheets is provided with a notch 21 between the blocks 13 on one side edge and a notch 22 between the blocks 13 on the opposite side edge. Then, when superimposed on the lower sheet 18 without notches, fork outlets 23 and 24 that gradually increase inward in a stepwise manner are formed on the opposite side edges with the two escape holes 20 interposed therebetween.
[0021]
When using the illustrated cargo handling pallet 10, an article is placed on the top plate 11, and a fork of a hand lift truck that is a cargo handling equipment is inserted from one fork loading / unloading port 23.
[0022]
For example, as shown in FIG. 3, the hand lift truck 30 includes a pair of elongated forks 32 that protrude in parallel from the main body 31 and horizontally hold them, and are provided at the front ends of the wheels 33 and the forks 32 provided on the main body 31. The fork 32 can be lifted while maintaining the horizontal state by pulling the lever 35 in the direction of the arrow about the support shaft 36, and the release lever 37 can be pulled. Thus, the fork 32 can be lowered by releasing the hydraulic pressure.
[0023]
Now, the tips of the pair of forks 32 of the hand lift truck 30 are brought close to the two fork outlets 23 on one side edge as shown in FIG. 4, and the wheels 34 are rolled as shown in FIG. Is inserted into the cargo handling pallet 10 through the fork loading / unloading port 23, the wheel 34 comes into contact with the side edge of the lower sheet 18 of the bottom plate 12 as shown in FIG. When the fork 32 is further inserted, the wheel 34 can be ridden on the lower seat 18 as shown in FIG. 5 (C) and then ridden on the bottom plate 12 as shown in FIG. 5 (D).
[0024]
In this manner, the wheel 34 is rolled through the fork insertion / removal port 23 that gradually increases inward so as to easily ride on the bottom plate 12, thereby facilitating the insertion work of the fork 32 of the hand lift truck 30 into the pallet 10. It can be. Only the fork entrance / exit 23 that gradually increases inward is formed, so that it is easy to process, and there is no particular increase in cost, and there is nothing that protrudes, resulting in loss of storage space. There's nothing to do.
[0025]
Then, the wheels 34 are rolled to move on the bottom plate 12, pass through the positions of the two escape holes 20 and pass through the cargo handling pallet 10, and as shown in FIG. Through the pallet 10.
[0026]
As a result, the lever 35 of the hand lift truck 30 is pulled many times around the support shaft 36 to raise the pair of forks 32 relatively, lift the cargo handling pallet 10 on which the article is placed, and the hand lift truck 30 By pushing, the wheels 33 and 34 run and can be manually transported to a desired position.
[0027]
In the above description, the tip of the fork 32 protrudes from the front of the cargo handling pallet 10. However, the wheel 34 is inserted into the escape hole 20 and inserted into the pallet 10 halfway without penetrating the fork 32. The wheel may be moved downward through the escape hole 20 at the position, and the pallet 10 may be lifted and transported.
[0028]
After transportation, the hydraulic pressure is released by pulling the release lever 37, the pair of forks 32 are relatively lowered, and the cargo handling pallet 10 on which the article is placed is lowered. Then, as shown in FIG. 7, the fork 32 is pulled out from the cargo handling pallet 10 in the direction of the arrow. At this time, in the illustrated example, since the inward fork entrance / exit 24 that gradually increases in the opposite side edge of the bottom plate 12 facing the side edge having the fork entrance / exit 23 is provided, the direction is shown in FIG. The pull-out operation of the fork 32 after the insertion can be facilitated by making it easy to ride the wheel 34 on the bottom plate 12 as in the insertion.
[0029]
By the way, in the above-described example, the escape holes 20 for escaping the wheels 34 of the handlift truck 30 are formed in the bottom plate 12. However, as shown in FIG. When the access port 25 is formed, the wheel 34 can be easily inserted and removed from the escape hole 20 when the fork 32 is inserted from the direction of arrow A.
[0030]
Further, as shown in FIG. 9, if fork entrance / exit ports 26 and 27 that gradually increase inward are provided on the adjacent side edges of the bottom plate 12 orthogonal to the side edges having the fork entrance / exit ports 23 and 24, the direction of the arrow A Not only that, but also the fork 32 can be easily inserted from the direction of the arrow B perpendicular thereto, and workability can be improved.
[0031]
At this time as well, as shown in FIG. 9, if the fork entrance / exit 28 that gradually increases stepwise is formed at the periphery of the escape hole 20 as well, the escape hole 20 when the fork 32 is inserted from the direction of the arrow B. The wheel 34 can be easily taken in and out.
[0032]
In the example described above, the notches 21 and 22 are provided between the blocks 13 of the upper sheet 17 provided on the upper side of the stacked sheets in the bottom plate 12. However, as shown in FIG. 10, the notch 40 is provided between the blocks 13 of the lower sheet 18 provided on the lower side of the sheets to be overlapped, and the notch is pressed when the leading end is pushed from above on the sheet 17 provided on the upper side. It is also possible to provide a tongue piece 41 that enters and tilts into the inside 40 and a fork entrance 42 that gradually increases inward in a slope shape.
[0033]
Then, the tips of the two forks 32 of the hand lift truck 30 are brought close to the two fork entrances 42 on one side edge as shown in FIG. 10, and the wheels 34 are rolled as shown in FIG. 11 is inserted into the cargo handling pallet 10 through the fork loading / unloading opening 42, the wheel 34 comes into contact with the tip of the tongue 41 and pushes the tip from above as shown in FIG. Get inside and tilt. When the fork 32 is further inserted, as shown in FIG. 11 (C), the wheel 34 can be ridden on the tongue piece 41 to increase the inclination, and eventually can be completely ridden on the bottom plate 12.
[0034]
After transport, as shown in FIG. 12, the fork 32 is pulled out from the cargo handling pallet 10 in the direction of the arrow. At this time, in the illustrated example, on the opposite side edge of the bottom plate 12 opposite to the side edge having the fork outlet / outlet 42. In addition, since the fork insertion / extraction opening 43 is provided, the pulling-out operation of the fork 32 after insertion shown in FIG. 13 can be facilitated by making it easy to ride the wheel 34 on the bottom plate 12 as in the insertion.
[0035]
As shown in FIGS. 14 and 15, the fork entrance / exit ports 23, 25 that gradually increase in a step shape and the fork entrance / exit ports 42, 43 that gradually increase in a slope shape may be used in combination.
[0036]
In the above description, the case where the bottom plate 12 is formed by overlapping two sheets has been described. However, the bottom plate is not limited to the case where the sheets are formed by overlapping sheets, and three or more sheets are stacked. You may make it form.
[0037]
