[0009]
When transferring the items in the box body to a truck bed or other container, when the holding grooves are provided on both outer walls of the support groove, the interval between the forks inserted into the support grooves is increased. Insert a fork into each holding groove. When each holding groove is provided on both inner side walls of the support groove, the fork is inserted into each holding groove with the interval between the forks narrowed. When the fork is inserted into each holding groove, the fork is rotated above the loading platform or other container, so that the box body is inverted so that the bottom plate is on the upper side. At this time, the box body keeps being held on the fork by the holding groove. Thereby, a conveyed product can be dropped to a loading platform, another container, etc. from the inside, and can be reloaded.
[0010]
When the transshipment of the conveyed product is completed, the fork is rotated and the box body is reversed and returned to the original state so that the bottom plate is on the lower side. Narrow or widen the fork interval to support the box body with the support groove, and lower the fork to place the box body. The fork can be removed from the support groove and the above process can be repeated with another forklift box.
[0011]
As described above, the forklift box according to the present invention can be held and inverted by the fork, so that the transported goods can be easily reloaded. In addition, since the structure can be simple, durability can be improved and manufacturing costs can be reduced.
[0012]
In the present invention, the support groove may be composed of two in accordance with the fork of the forklift, or may be composed of one so that each fork can be inserted simultaneously. When there are two supporting grooves, the holding grooves may be provided on both outer side walls or both inner side walls of each supporting groove. It is preferable to be provided on both outer walls. In the case of a single support groove, the holding grooves are provided on both outer walls of each support groove.
[0013]
In the present invention, the interval between the holding grooves is preferably substantially equal to or slightly larger than the thickness of the fork. In addition, an elastic member such as rubber or urethane may be provided on the inner surface of each holding groove in order to increase the holding force of the fork and suppress backlash.
[0014]

The support groove 12 includes two parallel grooves 14 and 15 having a rectangular cross section. Each groove 14, 15 has a width larger than the width of the fork 1 of the forklift and a depth larger than the thickness of the fork 1. In one example, the width of each groove 14, 15 is 1.5 to 3 times the width of the fork 1, and the depth is twice the thickness of the fork 1. The two grooves 14 and 15 are formed on the outer surface of the bottom plate 11a with a space at which the fork 1 can enter both the grooves 14 and 15 at the same time.
[0019]
Two sets of the support grooves 12 are formed with two parallel grooves 14 and 15 as one set. Each support groove 12a, 12b is provided in parallel to the length direction and the width direction of the bottom plate 11a, respectively. One support groove 12a is formed with two grooves 14a and 15a at positions symmetrical with respect to the center line of the opposing sides in the length direction of the bottom plate 11a. The other support groove 12b is formed with two grooves 14b and 15b at positions symmetrical with respect to the center line of opposite sides in the width direction of the bottom plate 11a. Each support groove 12a, 12b is provided open to the side plate 11b side so that the fork 1 of the forklift can be inserted from the side plate 11b side.
[0020]
Each holding groove 13 has a rectangular cross section. Each holding groove 13 has an interval slightly larger than the thickness of the fork 1 so as to hold the fork 1 in the thickness direction. Each holding groove 13 has a width smaller than the width of the fork 1. In one example, the interval between the holding grooves 13 is 1.25 times the thickness of the fork 1, and the width is about 2/3 times the width of the fork 1.
[0021]
The holding grooves 13 are provided in pairs in the two sets of support grooves 12a and 12b. Each holding groove 13 is provided perpendicularly to the outer wall of each groove 14a, 15a, 14b, 15b along the ceiling surface of each groove 14a, 15a, 14b, 15b of the support groove 12a, 12b. Each holding groove 13 has an upper side wall connected to the ceiling surface of each groove 14a, 15a, 14b, 15b in a flat manner. Each holding groove 13 is provided open to the side plate 11b side so that the fork 1 of the forklift can be inserted.
[0022]
In the specific example of the forklift box 10, the box body 11 has a length of 1695 mm, a width of 1230 mm, and a height of 715 mm. The grooves 14a and 15a of the support groove 12a have a width of 350 mm and a depth of 80 mm, and the length between the inner surfaces of the grooves 14a and 15a is 300 mm. Each of the grooves 14b and 15b of the support groove 12b has a width of 200 mm and a depth of 80 mm, and the length between the inner surfaces of the grooves 14b and 15b is 300 mm. Each holding groove 13 has an interval of 50 mm and a width of 80 mm. The fork 1 of the forklift has a thickness of 40 mm and a width of 125 mm, for example.
These numerical values are merely examples, and those having other dimensions can be used freely.
[0023]
Next, the operation will be described.
The forklift box 10 is used for carrying a transported object inside the box body 11. The forklift box 10 is transported by inserting the fork 1 of the forklift straight into the support groove 12 opened to the side plate 11 b side and lifting the box body 11 with the fork 1. At this time, the forklift box 10 is supported by the ceiling surface of the support groove 12. In the forklift box 10, since the support grooves 12a and 12b are provided open to the four side plates 11b, the fork 1 can be inserted and transported from any of the four directions.
[0024]
The forklift box 10 can widen or narrow the interval between the forks 1, and is particularly effective when used with a forklift that can rotate the fork 1 about an axis parallel to the fork 1. To do.
[0025]
In the case of transshipping the transported object inside the box main body 11 to a truck bed or other container, as shown in FIG. The fork 1 moves along the ceiling surfaces of the grooves 14 and 15 of the support groove 12 and is inserted into the pair of holding grooves 13. At this time, since each holding groove 13 has an interval slightly larger than the thickness of the fork 1, the fork 1 can be inserted smoothly.
[0026]
If the fork 1 is inserted into each holding groove 13, the fork 1 is rotated above the loading platform or other container to invert the box body 11 so that the bottom plate 11a is on the upper side. At this time, the box main body 11 is maintained in the fork 1 by the holding grooves 13 and does not fall. Thereby, a conveyed product can be dropped to a loading platform, another container, etc. from the inside, and can be reloaded. For this reason, transshipment work can be performed without requiring human power.
[0027]
When the transshipment of the conveyed product is completed, the fork 1 is rotated, and the box body 11 is reversed and returned to the original state so that the bottom plate 11a is on the lower side. When the interval between the forks 1 is reduced, the forks 1 move from the holding grooves 13 to the support grooves 12 along the ceiling surface. The box body 11 is supported by the ceiling surface of the support groove 12, the fork 1 is lowered, and the box body 11 is placed. The fork 1 can be removed from the support groove 12 and the above steps can be repeated in another forklift box 10.
[0028]
Thus, since the forklift box 10 can be held and reversed by the fork 1, it is easy to reload the conveyed product. Further, the forklift box 10 can have a simple structure in which the holding groove 13 is simply formed in the conventional box, so that the durability can be improved and the manufacturing cost can be reduced.
[0029]
As shown in FIG. 2, the fork 1 may have protrusions 1a on both outer side surfaces. In this case, it is preferable that the side surface of the holding groove 13 has a fitting portion into which the protruding portion 1a can be fitted. In this case, when the forklift box 10 is held by the fork 1, the protrusion 1 a of the fork 1 is fitted into the fitting portion of the holding groove 13. For this reason, it is possible to prevent the forklift box 10 from being displaced in the length direction of the fork 1 and falling off the fork 1 during transportation and rotation.
[0030]
