Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pallet that is lifted by inserted forklift claws and configured to carry a loaded load.
[0002]
[Prior art]
Conventionally, pallets that are lifted by inserted forklift claws and configured to carry loaded cargo are arranged in parallel at intervals as shown in FIGS. 16 and 17, for example. A wooden upper plate 3 called a plurality of deck boards is stretched on the upper surface of a plurality of wooden girders 1 having a rectangular cross section to form an upper horizontal plane UH on which a load C is placed. 2. Description of the Related Art A portion in which a pair of claw insertion portions I of a forklift is formed in a portion surrounded by an upper plate 3 is known. FIG. 17 shows a wooden lower plate 2 stretched on the lower surface of the beam 1.
[0003]
However, the pallet has the following drawbacks.
(A) It is not possible to unload only with luggage C with a forklift.
The load C placed on the upper horizontal plane UH of the pallet is generally inserted between the lower surface of the load C and the upper horizontal plane UH of the pallet and lowered by the forklift. There is a drawback that it is not possible to unload only the luggage C.
Therefore, there is only a method for unloading the load C by another means, and even if all the loads C are unloaded and no load is left on the pallet, even if only the pallet is moved and collected, it cannot be moved.
[0004]
For example, when a plaster board used as a wall material is transported for a very short distance, it can be directly loaded and unloaded by a forklift. However, in the case of long distance transportation requiring a truck or the like, it is generally placed on a pallet to prevent breakage or the like. In this case as well, even if the forklift pawl is inserted between the lower surface of the plaster board and the upper surface of the pallet at the transport destination, and the forklift tries to lower it, there is no gap between which the nails can be inserted, and only the plaster board is lowered. I can't.
Accordingly, the plasterboard can only be lowered by another means, and even if all the plasterboards are lowered and there is no plasterboard on the pallet, the pallet alone cannot be recovered. Therefore, the pallet must remain at the destination, take up space, and come again to retrieve the pallet at a later date.
[0005]
(B) It is difficult or impossible to both band the loaded luggage and remove the band from the luggage.
A general baggage C having a flat bottom surface and almost no gap with the pallet cannot pass the band between the pallet upper horizontal plane UH and the baggage C, so that it is difficult or impossible to hang the bandage on the baggage C. It is. Similarly, a band hung only on a load can be cut with a scissors or the like, but it is difficult or impossible to pull out and remove. In particular, if a metal band is cut, a sharp cutting part will protrude and it is dangerous for work.Therefore, it is necessary to remove it, but if you try to remove it, you may be injured and dangerous. It is.
[0006]
There are not only wooden pallets but also plastic and metal pallets, both of which have the above disadvantages because they have a flat upper surface.
[0007]
[Problems to be solved by the invention]
Accordingly, an object of the present invention is to provide a pallet that can remove only the load by using a forklift and can easily remove and remove the band, eliminating the above two disadvantages of the conventional pallet. There is.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the pallet of the invention of claim 1 has an upper horizontal plane (UH) on which a load (C) can be placed, and the left and right sides of the forklift that moves up and down below the upper horizontal plane (UH). A pair of claws ( I) into which a pair of claws (F) are horizontally inserted from the side surfaces are formed, and the pallets are lifted or lowered by raising and lowering the forklift claws (F),
A groove (G) is formed in the upper horizontal plane (UH) so that the claw (F) of the forklift can be inserted horizontally from the side and parallel to the insertion direction of the insertion section (I). The depth of (G) is deeper than the height of the claw (F) of the forklift, and the groove width is wider than the width of the claw (F) and is lower than the position of the upper horizontal plane (UH) inserted horizontally from the side surface. The claw (F) in the position can be raised to a position higher than the position of the upper horizontal plane (UH), and only the loaded luggage (C) can be lifted separately from the upper horizontal plane (UH) , The claw insertion portion (I) and the groove (G) are disposed adjacent to each other with a partition wall therebetween, and the claw (F) is inserted into a part of the partition wall with the claw (F) of the forklift. Is moved from the nail insertion portion (I) to the left-right direction perpendicular to the insertion direction. It is characterized in that the claw insertion portion from the groove in the or conversely (G) (G) opening capable of penetrating freely in (I) (O) is formed.
[0009]
In the invention of claim 2, in addition to the structure of the invention of claim 1, the upper plate (34) forming the upper horizontal plane (UH) is provided on the upper surface of the lower plate (25) and the lower plate (25). Between the several vertically arranged girders (16), either one of the left and right ends is stretched to be a free end projecting from the girders (16), and the partition wall is formed by the free ends. As it is formed,
The claw insertion portion (I) is formed between the protruding free end portion and the lower plate (25), and the groove (G) is a portion where the upper plate (34) is not stretched. It is characterized by being formed .
[0010]
According to a third aspect of the present invention, in addition to the structure described in the second aspect of the invention, the free end of the upper plate (34) has a downward facing to prevent the forklift pawl (F) from coming off when the pallet is lifted. The protrusion (P) is provided in a protruding manner .
[0011]
The symbols in the parentheses correspond to the symbols described in the drawings and embodiments of the invention described later.
[0012]
According to the first aspect of the present invention, the forklift pawl inserted into the groove can be freely raised from a position lower than the position of the upper horizontal plane to a position higher than the upper horizontal plane. Even if the lower surface of the baggage is flat, it is easy to insert a forklift claw under it, and only the baggage can be lifted separately from the pallet by raising and lowering the claw. In this way, during transportation, only the load can be lifted, transported and unloaded at the destination by the forklift, so that the pallet can be taken home, and there is no need to come to collect the pallet later.
In addition, since there is no need to replace the claw between the claw insertion portion and the groove, the forklift is not advanced or retracted. Therefore, the pallet on which the load is placed and the loading / unloading of the load can be carried out by the same forklift only by moving the left and right and up and down slightly with the pawls of the forklift inserted.
[0013]
In addition, not only the claw but also the band can be inserted and passed into the groove, so even if the load is placed on the pallet and the bottom surface is flat, the band can be passed through the groove. Banding can be done easily. In addition, as described above, the band only hung on the luggage is not restrained by the luggage and the pallet, and can be easily pulled out and removed through the groove when cut. In particular, a sharp cutting portion protrudes when cut, and a metal band which is dangerous in operation can be easily removed without cutting if it is cut and pulled.
[0014]
According to claim 2, the nail insertion portion of the invention of claim 1 is formed between the protruding free end portion and the lower plate, and the groove of the invention of claim 1 is formed by the upper plate being stretched. It is formed in the part which is not done.
[0015]
According to the third aspect of the present invention, since the downward projection protrudes from the free end of the upper plate, it is possible to prevent the forklift claw from being pulled out when lifting the pallet.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a pallet according to a first embodiment of the present invention, FIG. 2 is a sectional view showing a state in which a load is placed on the pallet in FIG. 1, and FIG. 4 is a cross-sectional view showing a state in which the pawl of the forklift is in the groove, FIG. 4 is a cross-sectional view showing a state in which the pawl of the forklift is inserted into the pawl insertion portion, and FIG. 6 is a cross-sectional view showing a state where the band is cut, and FIG.
[0017]
The pallet according to the embodiment of the present invention has an upper horizontal plane UH on which a load C can be placed, and a nail difference in which a forklift claw F that moves up and down is inserted horizontally from the side below the upper horizontal plane UH. The following structure is further added to what the insertion part I was formed, and was lifted or lowered by raising / lowering the nail | claw F of a forklift.
[0018]
That is, grooves G and G are formed in the upper horizontal plane UH so that the forklift pawl F can be inserted horizontally from the side and parallel to the insertion direction of the insertion portion I. The depth of the groove G, that is, the depth of the claw F in the up-and-down direction (vertical direction in FIG. 3) is deeper than the height of the claw F of the forklift and the width of the groove G, that is, a pair of claw adjacent to the claw F. The width in the horizontal lateral direction (left and right direction in FIG. 3) where F is located is wider than the width of the claw F, whereby the claw F is positioned lower than the position of the upper horizontal plane UH inserted horizontally from the side surface. It is configured to be able to ascend to a position higher than the position of the upper horizontal plane UH so that only the loaded luggage C can be separated from the upper horizontal plane UH and lifted.
[0019]
More specifically, as shown in FIG. 1 and FIG. 2, a plurality of rectangular cross-section wooden pieces perpendicular to the upper surface of the plurality of wooden lower plates 21 arranged with little or no gap. Are arranged in parallel and fixed with nails or the like (not shown). In the figure, girders 11 and 11 are arranged at both ends of the lower plate 21, and a pair of girders 11 and 11 are arranged on both sides of the middle point of the length of the lower plate 21. The pair of girders 11 and 11 in the central portion are arranged at intervals at which the forklift claws F and F can be inserted, and further are made of wooden plates provided between a pair of opposite girders 11 and 11. A space between the beams 11 and 11 is vertically divided by the partition wall HP, and a claw insertion portion I is disposed below and a groove G is disposed above. In addition, an upper plate 31 is stretched between the inner girds 11 and 11 of each pair and between the outer gird 11 and the gird 11 at each end of the lower plate 21 and fixed with nails or the like (not shown). Thus, the upper horizontal plane (UH) is formed.
[0020]
The action C will be described. Even when the load C placed on the pallet has a flat bottom surface, as shown in FIG. 3, the nails F inserted into the grooves G, G formed in a straight line and parallel to each other, as shown in FIG. , F can be lifted upward in the vertical direction beyond the upper horizontal plane UH, and only the loaded cargo C can be lifted separately from the pallet. Therefore, at the time of transportation, only the load C can be lifted by a forklift at the destination, and can be transported to a place where it is lowered, so that the pallet can be taken home and there is no need to return the pallet for collection later.
[0021]
Moreover, as shown in FIG. 3 and FIG. 4, since the groove G is arranged directly above each claw insertion portion I across the partition wall HP, between each claw insertion portion I and the corresponding groove G, The replacement of the claw F is performed only by moving the forklift back and forth and raising and lowering the claw F only slightly, so that not only the transportation of the pallet on which the load C is placed but also the loading and unloading of the load C can be performed by the same forklift. It has excellent workability and is very convenient.
[0022]
If it is not particularly necessary to load and unload the cargo C, the pallet can be turned over (not shown) and the cargo C can be placed with the surface on which the lower plate 21 is stretched as the upper surface.
[0023]
Further, not only the claw F but also the band B can be inserted and passed through each groove G as shown in FIGS. 5 and 6, so that the load C placed on the pallet with a flat bottom surface can be used. By passing the band B through the groove G, it is possible to easily hang the band only on the load C. Further, as described above, the band B hung only on the luggage C is not restrained by the luggage C on the pallet and can be easily pulled out and removed by cutting with a scissors or the like. In particular, a sharp cutting portion protrudes when cut, and a metal band which is dangerous in operation can be easily removed without cutting if it is cut and pulled.
[0024]
Next, the second embodiment will be described with reference to FIGS. 7 and 8. The partition wall HP provided between the girders 11 and 11 in the center of the first embodiment is omitted, and each gird 11 , 11 functions as a groove G, and the lower space of each upper plate 31 functions as a claw insertion portion I.
[0025]
The operation will be described. When lifting only the loaded cargo separately from the pallet, the forklift claw F inserted into the deepened linear groove G is used in the same manner as in the first embodiment. It can be lifted over the upper horizontal plane UH.
On the other hand, unlike the first embodiment, when replacing the nail F between each nail insertion portion I and the groove G, the forklift is moved backward, and the nail F is once extracted. Then, the forklift is moved forward again and the pawl F is inserted. Further, as shown in FIG. 8, the weight of the load C placed on the upper horizontal plane UH is received by the upper plates 31, 31 supported by the claws F, F, and the partition wall HP in terms of strength. The case of the first embodiment having the above is stronger.
[0026]
The third embodiment will be described with reference to FIG. 9. A plurality of sheets arranged in parallel with a slight gap between the top and bottom sides of a plurality of short girders 12 arranged in parallel. A wooden lower plate 22 and an intermediate plate 42 are stretched and fixed with nails or the like (not shown). In addition, the girders 12 and 12 are arranged at both ends of the plates 22 and 42, respectively, and a pair of left and right nail insertion portions I and I are formed at the center of the plates 22 and 42 at the midpoint of the length. A total of three girders 12 are arranged (one in total and two midpoints on the outside), for a total of five girders.
[0027]
On the middle plate 42, a short girder 13 is fixed immediately above each girder 12, and an upper plate 32 is stretched between adjacent outer girders 13 on the left and right sides. At the same time, a short plate S for receiving a load symmetrically is fixed to the upper surface of the central beam 13 with nails or the like (not shown). As a result, an upper horizontal plane UH is formed by the upper plates 32 and 32 and the short plate S, and a partition wall HP which is an intermediate plate 42 is provided immediately above the claw insertion portions I and I in the central portion. A pair of left and right grooves G and G partially closed by the short plate S are formed.
[0028]
The operation is basically the same as that of the first and second embodiments, but the weight of the load placed on the upper horizontal plane UH is received by the intermediate plate 42 through all the girders 12. Therefore, the load distribution is distributed and the strength is excellent as compared with the case of receiving only at the joint portion between the beam 11 and the partition wall HP in the first embodiment.
[0029]
As shown in FIG. 10, the fourth embodiment is a simplified type of the third embodiment, in which the central beam 13 and the short plate S provided thereon are omitted. The function and effect are substantially equal to those of the second embodiment.
[0030]
The fifth embodiment will be described with reference to FIG. 11. A plurality of sheets arranged in parallel with a few gaps on the upper and lower sides across a plurality of short girders 14 arranged in parallel. A wooden lower plate 23 and an intermediate plate 43 are vertically stretched and fixed with nails or the like (not shown). In addition, the girders 14 and 14 are arranged at both ends of the plates 23 and 43, respectively, and four pairs of left and right nail insertion portions I and I are formed symmetrically on both sides of the middle point so that a center portion is formed. A digit 14 is arranged.
[0031]
On the middle plate 43, a short girder 15 is fixed immediately above each girder 14, and an upper plate 33 is stretched between adjacent outer girder 15 and 15 on the left and right sides. At the same time, an upper plate 33 is stretched on the upper surfaces of the adjacent adjacent girders 15 and 15 and fixed with nails or the like (not shown). Thereby, an upper horizontal plane UH is formed by the upper plate 33, and a pair of left and right grooves G, which are separated from each other by a partition wall HP, which is an intermediate plate 43, are directly above the claw insertion portions I, I at the center. G is formed. The operational effects are the same as those of the third embodiment.
[0032]
The sixth embodiment is a modification of the fifth embodiment. As shown in FIG. 12, instead of the lower plate 23, the upper plate 33 and the adjacent outer sides on the left and right sides are used. A lower plate 24 is stretched between the girders 14 and 14, and a lower plate 24 is also stretched on the lower surface of the adjacent girders 14 and 14 at the center. Accordingly, the pair of left and right nail insertion portions I and I in the center portion are open at the bottom and are vertically symmetric. Therefore, when turned upside down, the corresponding groove G and the nail insertion portion I are interchanged to distinguish the front and back sides. It can be used without.
[0033]
The seventh embodiment will be described with reference to FIG. 13 and FIG. 14. A plurality of rectangular cross sections are perpendicular to the upper surface of the plurality of wooden lower plates 25 arranged with little or no gap. Wooden girders 16 are arranged in parallel and fixed with nails or the like (not shown). In the figure, girders 16 and 16 are arranged at both ends of the lower plate 25, respectively, and an even number (four in the figure) 16 and 16 are arranged in the middle of the upper surface inside the lower plate 25.
[0034]
Further, among the digits 16, the upper end surface between the two digits 16 at the center (the third and fourth digits 16 from the left in FIG. 13) and the two digits 16 at the remaining end side (1 from the left in FIG. 13). A plurality of upper plates 34 are stretched on the upper end surface between the second and second girders 16 and the fifth and sixth girders 16 from the left, and are fixed with nails or the like (not shown). Is formed. Thus, the forklift claw F similar to that described in the first embodiment can be horizontally inserted into the portion where the upper plate 34 of the upper horizontal plane UH is not stretched from the side surface, and an insertion portion described later. Two grooves G, G parallel to the insertion direction of I are formed.
[0035]
At this time, the upper plate 34 stretched on the upper end surfaces of the fifth and sixth girders 16 from the left as well as the upper plate 34 stretched on the upper end surfaces of the third and fourth girders 16 from the left in FIG. The upper plate 34 is wider than the interval between the two girders 16, and the upper plate 34 is stretched with the end portion protruding from the girders 16. That is, the upper plate 34 stretched on the upper end surfaces of the third and fourth girders 16 from the left in FIG. 13 becomes a free end protruding from the third girder 16 to the second girder 16 side, and is fifth from the left. The upper plate 34 stretched on the upper end surface of the sixth girder 16 is a free end projecting from the fifth girder 16 to the fourth girder 16 side.
Thereby, between the protruding part and the lower plate 25, the nail insertion portions I and I into which the pair of left and right claws F and F can be inserted are formed, and the nail insertion portions I and I Between the grooves G and G, openings O and O are formed so that the two claws F and F of the forklift can be freely moved in and out. That is, the protruding portion of the upper plate 34 described above serves as a partition that separates the claw insertion portions I and I and the grooves G and G in an adjacent state, and the opening portion is a portion obtained by removing a part thereof. Thus, the forklift claws F, F can freely penetrate the claw insertion portions I, I to the grooves G, G, or conversely the grooves G, G to the claw insertion portions I, I.
[0036]
In order for the above configuration to function, for example, as shown in FIG. 13, a pair of adjacent girders 16 and 16 (third and fourth from the left) at the center are respectively connected to the nail insertion portions I and I. While entering between the inserted two claws F, F, the inner surface of one (left side) of the two claws F, F is in contact with the outer surface of the spar 16 (third from the left) on the near side. In this state, the remaining girder 16 needs to be arranged so that the outer surface of the other claw F (right side) does not exceed the outer surface of the girder 16 (fifth from the left) arranged outside the claw F. .
As shown in the figure, the free end of the upper plate 34 is provided with a downward projection P for preventing the claw from being pulled out when lifting the pallet. However, as long as it is based on the basic configuration of the present invention. The configuration is not limited to the above.
[0037]
As for the operation, the pallet can be lifted by the claw F inserted into each claw insertion portion I via the free end side portion of the upper plate 34, and the loaded cargo C is Even when the claw is flat, the claw F inserted into each claw insertion portion I is moved slightly horizontally through the opening O and lifted from the groove G over the upper horizontal plane UH. Only the load C can be lifted separately from the pallet. That is, it is possible to switch between lifting the pallet and lifting only the loaded cargo C by moving the claw F slightly left and right and up and down, and it is not necessary to advance or retract the forklift for replacing the claw.
[0038]
Each nail insertion portion I is not shown, but not only the nail F but also a band can be inserted, and the groove G can be passed through the band. It is possible to easily hang the band only on C and to cut and remove the band only on the luggage.
[0039]
As shown in FIG. 15, the eighth embodiment is a modification of the seventh embodiment, in which a lower girder 17 is used instead of the girder 16. A bottom plate 26 that is the same as the lower plate 25 is stretched on the lower surface of the lower girders 18 that are arranged directly below the respective girders 17, and the operational effect is between the lower plate 25 and the bottom plate 26. In addition to being usable as a nail insertion part, it is substantially equivalent to the seventh embodiment.
Since the weight of the loaded luggage is received by the lower plate 25 through all the girders 18, the load distribution is distributed compared to the case of the seventh embodiment, Excellent in strength.
[0040]
The pallet of the present invention includes not only wooden items but also plastic and metal items.
[0041]
【The invention's effect】
According to the first aspect of the present invention, only the loaded cargo can be lifted separately from the pallet. Therefore, during transportation, only the load can be lifted, carried and unloaded at the destination by a forklift, so that the pallet can be taken home and there is no need to come back to collect the pallet later.
In addition, since there is no need to replace the claw between the claw insertion portion and the groove, the forklift is not advanced or retracted. Therefore, the pallet on which the load is placed and the loading / unloading of the load can be carried out by the same forklift only by moving the left and right and up and down slightly with the pawls of the forklift inserted.
[0042]
In addition, it is possible to easily band only the luggage placed on the pallet. Furthermore, the band hung only on the load as described above is not restrained by the load and the pallet, and can be easily pulled out and removed through the groove when cut.
[0043]
