Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet, a method of manufacturing the pallet, a forklift used for transferring a load placed on the pallet, a cargo handling system using the pallet and the forklift, and The present invention relates to a partition plate used in the cargo handling and transporting system.

[0002]

2. Description of the Related Art Conventionally, cargo handling and transportation using a forklift and a pallet is generally performed as follows, for example, in a fresh food market. That is, (1) when the cargo is placed directly on the truck bed after the truck is loaded, the cargo is reloaded onto the pallet of the wholesaler via the roller and the pallet is transferred to the pallet of the middle wholesaler. One method, (2) a second method in which the load placed directly on the truck bed is transshipped on the pallet of the wholesaler, the whole pallet is moved to the wholesaler by a forklift, and further transshipped to the pallet of the wholesaler or the pallet of the middle wholesaler. (3) When the cargo is loaded on the pallet of the carrier at the time of arrival, transship to the wholesaler's pallet, transfer this to the wholesaler with the pallet by a forklift, and further keep the wholesale pallet or middle wholesaler The third method of transshipping to pallets of (4) After moving the pallets of the carriers loaded with the pallets by a forklift, And transshipment to those skilled in the pallet, move to Naka wholesaler, or even there is a fourth method reloading the palette Nakaoroshi.

[0003] A forklift used in such a cargo handling operation includes two forks (claws), while a pallet has a horizontal fork insertion hole into which the two forks can be inserted. Is generally flat.

[0004]

However, there are the following problems in the forklift and pallet used in the above-mentioned conventional cargo handling system.

(1) The external dimensions of the pallets vary depending on the type of the goods to be conveyed, the type of conveyance, and the like. Even in a single market, the external dimensions of the pallets to be carried in are various. On the other hand, international standards for external dimensions of pallets
Although it is 1100 mm x 1100 mm, there is a problem that two pallets cannot be mounted in the width direction in consideration of the internal dimensions of a truck bed currently manufactured in Japan.

[0006] For example, the inner dimensions of a cargo bed of an 8 to 14 ton truck are 2340 mm in width (A type), 2
120mm (B type), 2040mm (C type),
There are seven types, 1840mm (D type), 1600mm (E type), 1500mm (F type), and 1320mm (G type), but two international standard pallets can be mounted in the width direction according to the internal method. Dimension is 2340
Only the A type, which is mm, and the other B type or G type trucks can mount only one international standard pallet. In particular, in the case of a pre-cooled vehicle or an insulated vehicle for transporting agricultural products, the inner dimensions of the cargo bed are further reduced, so that there is a disadvantage that a wasteful space is generated in the cargo bed and the transportation efficiency is poor.

(2) The work of transshipping the load between pallets
All must be done manually, and the work is complicated and heavy labor, and there are also labor and health problems in view of the aging of the workers. In addition, there is a problem that a large space is required for transshipment. Also, since it takes time for unloading, the so-called location competition is likely to take place in order to secure a relatively easy place to work in the market, and traffic in the market is congested.

(3) Since the pallets move together with the load, the management of the pallets owned by the transporter, the wholesaler and the middleman becomes complicated. For example, in order to avoid such complicated management of pallets, transporters often directly load a truck, which is a factor that increases the manual work. this is,
The same applies to the transfer of cargo between other industries and traders. Also,
For example, the carrier may retrieve as many pallets from the market as pallets unloaded from the truck with the load. In this case, there is a problem that the transporter tends to collect relatively new pallets, and relatively old pallets remain in the market.

The present invention has been made in order to solve the above-mentioned problems. The present invention has been made to improve the transportation efficiency of trucks, significantly reduce manual operations in cargo handling operations in markets and the like, and can control pallets. An object of the present invention is to provide an unnecessary pallet, a method of manufacturing the pallet, a forklift, a cargo handling system using the same, and a partition plate used in the cargo handling system.

[0010] The present invention relates to a commercially available product of about

[0018]

Next, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

According to the present invention, a load placed on a pallet having a multi-row groove is picked up by a forklift having a multi-row fork without lifting the pallet, and only the load is placed on another pallet or the like. The present invention relates to a technology, and thereby relates to a system capable of performing a cargo handling work in a short time by reducing manual work.

The pallet according to the present invention is shown in FIG.
As shown in (b), (с) and (d), the depth dimension is 1100 mm, which is the same as the international standard, and the width dimension is 110 mm.
0 mm pallet A, 1000 mm width pallet B, 550 mm width pallet C, 500 width dimension
Four types of pallets D of mm are set. In the figure, only the upper part of each pallet A, B, C, D is shown, and the lower part is omitted.

As the material of each of the pallets A, B, C, D, for example, any of wood, metal, synthetic resin, etc. can be adopted, but the use of recycled plastic (so-called waste plastic) is a resource. It is preferable to contribute to the recycling system. The thickness of the pallet is appropriately set. For example, the thickness of a metal pallet such as aluminum or stainless steel is preferably 67 mm to 140 mm, and the thickness of a recycled plastic pallet is 7 mm when used only as a stationary loading table.
5 mm to 85 mm, 150 m when movable
m to 170 mm.

According to the four types of pallets A, B, C, and D having the above outer dimensions, two or more pallets are mounted on all the trucks having various internal dimensions described in the prior art. This reduces wasteful space on the loading platform and increases the transportation efficiency. That is, for example, pallets A, B
(Width dimension is 1100mm + 1000mm), and C type has two pallets B (1000mm + 1000m).
m), D type pallet A or pallet B and C or D (1100 mm or 1000 mm + 550 mm)
Or 500 mm).

In this embodiment, the depth is set to 1100 mm according to the international standard. However, the present invention is not limited to this, and the depth can be set to 1000 mm or 1200 mm.

The pallets A,
B, C, and D are different from a conventional flat pallet having a flat upper surface, and a plurality of load receiving portions (top portions of mountain portions) having upper portions extending in the front-rear direction (depth direction) and grooves (valley portions) formed therebetween. ) Are alternately repeated in the width direction (left-right direction in the figure). A load (for example, a cardboard box containing fruits and vegetables) is placed over one load receiving portion or two or more load receiving portions.

The outside of each of the pallets B is 50 mm.
The pallet C is obtained by dividing the pallet A from the center, and the pallet D is obtained by dividing the pallet B from the center. In the pallet A, the width of the load receiving portions located at both ends in the width direction is 85 mm, and the width of the load receiving portion located at the center is 70 mm. The other receiving portions have a width of 80 mm, and the distance between all receiving portions is 90 mm. Therefore, the width of the load receiving portions located at both ends of the pallet B obtained by cutting off the outside of the pallet A by 50 mm is 35 mm, and the load receiving portions located at both ends of the pallet D obtained by further dividing the pallet B into two parts. Has a width of 35 mm. The widths of the load receiving portions located at both ends of the pallet C are 35 mm and 85 mm.

If the width of the receiving portion is smaller than 30 mm (especially 35 mm), it is difficult to secure the strength of the pallet made of resin (especially waste plastic) when the load is placed. Since it has been proved that this is the case, in the present embodiment, the minimum width dimension of the load receiving portion is set to 35 mm. If the width of the load receiving portions located at both ends in the axial direction is larger than 95 mm (especially 90 mm), when the cargo is loaded so that the corners are located at the outermost ends of the load receiving portions, the groove portions of the fork and the pallet, which will be described later, are used. Considering the play of the fork, it has been found that when this load is picked up with a fork, there is a problem that the amount of protrusion of the cardboard box from the outermost end of the fork becomes large, which causes wrinkles. This is set at 85 mm for safety.

On the other hand, the forklift according to the present invention
For example, as shown in FIG.
) (Hereinafter referred to as multi-row forks). The load is placed on one or more forks. The width of each fork is about 60 mm, and forks F, F
The distance between them is 113 to 105 mm. Further, in the present embodiment, the play between the fork and the groove of the pallet is 30 mm, respectively, but the difference between the width of the groove of the pallet and the width of the fork (so-called play) is such that each fork is inserted into the groove. Considering the operability at the time of insertion, the length may be 20 to 40 mm (preferably 24 to 30 mm).
mm). In the case of a forklift having eight forks, it is preferable that the width of the fork be approximately 45 mm and the distance between the forks be 101 to 85 mm. This is because it has been proved that when the width of the fork is smaller than 45 mm, the load pain caused by its own weight when the load is scooped increases.

The width of the fork inserted into the groove is 60
mm, the play becomes 26 mm, and there is no problem in operability. Each fork has a fixed position in the width direction. Therefore, in order for the pallets A, B, C, and D to be applicable to one forklift, it is necessary that the four types of pallets have a common receiving portion and groove.

For example, if the above-mentioned pallets A and B have seven load receiving portions and six groove portions, the pallets C and
In the case of D, there are four places for receiving parts and three places for grooves.
In this case, if the widths of the groove and the other load receiving portions sandwiched between the load receiving portions located at both ends and the central portion are all equal, the width of each load receiving portion and the groove becomes $ 100.
0− (35 × 2 + 70)｝ / 10 = 86 mm. 6
In the case of the present fork, the width of the fork is 60 mm × 6 and the play is (20 to 40 mm) × 6. The width of the part is 65 to 95 mm
Becomes On the other hand, in the case of eight forks, the width of the fork is 45 mm × 8, the play is (20 to 35 mm) × 8, the width of the six receiving parts is 56 to 36 mm, and the remaining 8 m
m may be adjusted at the load receiving portions at both ends and the center.

Considering the operability of loading and unloading the pallet by the forklift, it is necessary to provide a gap (play) of about 20 to 40 mm between each fork and each groove of the pallet. The experiment revealed this. Here, as the number of forks increases, the cumulative play increases, so it is appropriate to set the number of forks to about 4 to 8. As described above, the width of the pallet is limited (up to 1100 m).
m), the smaller the number of forks, the larger the contact between the load receiving portion of the pallet and the width of the fork and the load, and the less damage to the load. Then, as a result of repeating the experiment from 6 to 16 forks using a cardboard box containing vegetables and fruits, the load being small and the most fragile, the number of forks was 4 to 10, preferably 6 or more. At eight, it was demonstrated that the cargo was less damaged.

FIGS. 3A, 3B, 3C and 3D show another embodiment. In this embodiment, the width of the load receiving portion located at both ends of the pallet A and the width of the load receiving portion located at the center are both 90 mm, and the width of the load receiving portions located at both ends of the pallet B is 40 mm. ing. The width of the load receiving parts located at both ends is 45 mm and 90 mm for pallet C and 45 mm for pallet D.
And 40 mm. In addition, the other receiving portions have a width dimension of 75 mm at the outside and 70 mm at the inside. In addition, the distance between all the receiving parts is 90 mm.

In the embodiment shown in FIGS. 4A, 4B, 4C, and 4D, the width of the load receiving portion located at the center in the embodiment shown in FIG. The width dimensions of the located load receiving portions are all 75 mm.

As described above, the width of the central portion of the pallets A and B is 70 mm or more and 95% or more.
mm or less, and it is preferable that the dimensions of both ends of the pallet A be 85 mm or more and 95 mm or less in order to minimize the width of the load receiving portions located at both ends of the pallets B, C and D so that the load is not damaged. .

In each of the above embodiments, the pallet A has been described as an example in which the pallets B, C, and D can be easily manufactured using the pallet A as a basic model. However, at least one of the pallets B, C, and D is formed by independent molds. Needless to say, if the pallets C and D are not manufactured, as shown in FIGS. 5 (a) and 5 (b), the widths of the load receiving portions located at both ends of the pallet A 85 mm
And the width dimension of the centrally located
The pallet B can be manufactured by cutting the outer side of the pallet A by 50 mm at a time from 0 mm to 95 mm. In addition,
In the figure, only the load receiving portions located at both ends and the center are shown, but the width dimensions of the other load receiving portions are shown in FIGS.
Is set arbitrarily according to.

In each of the above embodiments, the load is small,
The most vulnerable, the cardboard boxes containing fruits and vegetables are exclusively loaded, or at least the dimensions of various pallets and forks are specified assuming that they are loaded with cardboard boxes containing fruits and vegetables, but it is difficult to damage the cargo Containers (for example, pallets and forks used for moving and storing large and small loads stored in racks made of resin, metal, wood, etc., styrofoam, and high-strength cardboard boxes, are located at both ends of the pallet. The width of the receiving part
The range can be expanded from 00 mm to 30 mm, and the width of the pallet can be 610 mm, 660 mm, or 1200 mm.

In the above-described embodiment, the forklift of the forklift in which the position in the width direction is fixed has been described. Therefore, the groove positions of the pallets A, B, C, and D need to be common. Therefore, pallets A and B
In the pallet A, the outer sides of both ends in the width direction of the pallet A must be cut off. In this case, in the pallet A, the width of the both ends is 35 mm, which is the minimum width of the pallet B. Must be 85 mm.

However, when the load placed on the pallet A is unevenly distributed in the width direction, or when the heavy object is unevenly distributed in one of the width directions, the balance is obtained when the forklift is used to scoop. Therefore, instead of inserting all the forks into the groove of the pallet, the forklift is shifted in the width direction and only three or four forks are inserted into the groove of the pallet, and the position of the center of gravity of the load and the lift of the load are lifted. It must be aligned with the center of gravity.

However, as in the above embodiment, the width of the load receiving portions located at both ends of the pallet A is 85 m.
If the distance is m, the width of the load receiving portion becomes wider than the distance between the forks, so that there is a problem that it is impossible to match the position of the center of gravity.

The embodiments shown in FIGS. 6A, 6B, 6C, and 6D have been made to solve such problems. In this embodiment, pallets A,
Instead of B, C, and D, a pallet E having a width of 1100 mm, a pallet F having a width of 1000 mm, a pallet G having a width of 550 mm, and a pallet H having a width of 500 mm are prepared.
Further, the present embodiment corresponds to a forklift having six forks. Fork width is 60m
m.

Each of the pallets E and F has a width of 50 to 55 mm at the load receiving portions located at both ends and a width of 90 mm at all the groove portions. The width dimension of the part is 100 to 90 mm. The width of one of the load receiving portions located at both ends of the pallets G and H is 50 to 45 mm, and the other is 50 to 55 m.
m. The width of all the other receiving parts of the pallets F and H is 65 mm, and the width of all the other receiving parts of the pallets E and G is 90 mm. The width of any of the receiving portions may take any value within a specific range, for example, 50 mm, 55 mm, etc.
It is needless to say that it is preferable to adopt a value of 5 mm unit for manufacturing.

As in the above-described embodiment, the pallet G may be obtained by dividing the pallet E into two parts from the center, and the pallet H may be obtained by dividing the pallet F into two parts from the center, or may be formed separately. Of course, you may do it.

The pallets E, F, G, H
Although it is conceivable to prepare a plurality of forklifts having fork intervals corresponding to each of the forklifts, in the present embodiment, as a method of coping with all the pallets E, F, G, and H with one forklift, a forklift having a fork width is used. It is proposed to be able to move in the direction and to enable alignment with the pallet groove. It goes without saying that various types of fork moving mechanisms are conceivable.

More specifically, in the forklift corresponding to the pallet F, the distance between the forks is 95 mm (130 to 120 mm in the center). The two forks (third and fourth counting from the left in the figure) do not move, and the two forks (second and fifth) located next from the center are moved outward by two.
The distance between the two forks becomes 120 mm by moving the outer two forks (the first and sixth forks) by 5 mm by moving the outer forks by 5 mm (130 to 120 mm at the center).

FIGS. 7A, 7B and 7C are explanatory diagrams of the operation of the embodiment of FIG. 6 (the description of the pallet G is omitted in FIG. 7). FIG. 6A corresponds to FIG. 6A, and shows that a plurality of forks moved so as to increase the distance between the forks fit into the recesses of the pallet. FIG. 6B corresponds to FIG. 6B, and shows that a plurality of forks moved so as to reduce the distance between the forks fit into the recesses of the pallet.
6 (d) correspond to FIG. 6 (d), and FIG.
(D) shows a case where a load is picked up by a fork, and the load is shifted to the center by one fork to stabilize the center of gravity of the forklift.
(E) shows that the load picked up from the pallet having a width of 500 mm in (d) is unloaded onto a pallet having a width of 1000 mm. In the figure, the pallets are loaded on the center of the pallet in a state shifted by one mountain, but it is needless to say that the pallets can be unloaded to any position.

FIGS. 8A, 8B, 8C and 8D show still another embodiment. This embodiment is an example in which the embodiment of FIG. 6 corresponds to a forklift having eight forks.

In the pallet E having a width of 1100 mm, the width of the load receiving portion located at both ends in the width direction is set to 50 to 55 mm, the width of the load receiving portion located at the center thereof is set to 100 to 90 mm, and Has a width of 41 mm and a groove has a width of 69 mm. Also,
In the pallet F having a width of 1000 mm, the load receiving portions located at both ends in the width direction are 50 to 55 mm, the load receiving portion located second from the both ends is 42 mm, and the load receiving portion located at the center is 100 to 90 mm. , The other receiving portion is 66 mm, and the width of all the groove portions is 69 mm.
mm. Further, the pallet H having a width of 500 mm is obtained by dividing the pallet F into two parts from the center (the former example is shown in FIG. 8D). In this embodiment, it is needless to say that it is preferable to use a value of 5 mm unit.

In the embodiment shown in FIG. 6 and FIG. 8, the width of the load receiving portions located at both ends of the pallet is 45 to 55 mm. Can be shifted in the width direction.

In each of the embodiments described above, the case where the number of forks of the multi-row forklift and the number of grooves of the pallet match has been described. However, the present invention is not limited to this. The number of grooves may not be the same (this includes an odd number of forks and an even number of pallet grooves).

The pallets having the above dimensions can be manufactured by employing various molding methods. However, when the pallets are made of resin, especially when they are made of recycled plastic, the following manufacturing method is used. It is preferable to employ it.

That is, as shown in FIGS. 9 (a) and 9 (b), first, the upper and lower portions have a plurality of irregularities in which a plurality of load receiving portions extending in the front-rear direction and grooves formed therebetween are alternately repeated in the width direction. A plurality of (two in this embodiment) pallets 101A and 101B are prepared, and the pallets 101A and 101B are overlapped vertically and horizontally in the same direction. The pallets 101A and 101B have the same shape, and have first through holes 105 formed at predetermined positions of the load receiving portion 103 (three positions in the front-rear direction). Holes 107 are formed (two locations in the front-rear direction). Further, large-diameter portions 105a and 105b into which bolts or nuts are inserted are formed on the front side and the bottom side of the first through hole 105, respectively.
A similar large diameter portion is formed on each of the front side and the bottom side of the through hole 107 (not shown).

Then, one of the pallets 101A is erected, and a bolt (preferably a resin bolt 109) is inserted from the front side of the first through hole 105 and protruded to the bottom side. A nut (preferably a resin nut 111) is fastened to the screw portion of the resin bolt 109 projecting to the bottom surface side, and the head of the bolt 109 is placed in the large diameter portion 105a on the front surface, and the nut 111 is connected to the large diameter portion 105b on the bottom surface. Within. In this state, the tip of the bolt 109 projects from the pallet 101A.

Next, the other pallet unit 101B is erected, and the two pallet units 101A and 101B are inserted so that bolts 109 are inserted into the first through holes 107 thereof.
(The nut 111 enters the large-diameter portion 105a on the front surface of the pallet 101B). Finally, a resin nut 113 is attached to the screw portion of the bolt 109 projecting into the large-diameter portion 105b on the bottom surface of the pallet 101B. To conclude.

The finally manufactured pallet has a resin bolt 109 located on the front side and a pallet unit 10.
The dimensions of each part are set such that the head protrudes about 2 mm from the surface of the pallet 1A and the head of the resin nut 113 located on the bottom side protrudes about 2 mm from the surface of the pallet 101B. These bolt heads and nut heads are provided with anti-slip processing, which prevents slippage between the ground or the loading platform and the pallet, and slips between the pallet and the load loaded on the pallet. Can be stopped.

As described above, if a multi-row fork is inserted into the groove of the pallet alone located above, only the load can be lifted while the pallet remains, and the multi-row fork can be inserted into the groove of the pallet alone located below. If the pallet is inserted, it is possible to lift the load together with the pallet or to place the pallet further on the load, that is, a so-called stacking.

The above manufacturing method is applied to a plurality of pallets 1
Although an example in which 01A and 101B are superimposed in the same direction has been described, superimposition may be performed in a back-to-back state. In this case, the pallets 101A and 101B
The through holes 107, 107 communicate with each other, so that not only the first through hole 105 but also the second through hole 107 can be connected to the bolt and the nut.

Also in the second through hole 107, the resin bolt 109 and the resin nut 113 are fastened, so that their heads can be slip-proofed. Is the same as The non-slip provided on the bottom side of the second through-hole 107 contributes to the non-slip between the ground or the loading platform and the pallet similarly to the one provided on the bottom side of the first through-hole 105, and in particular, the pallet When the single bodies 101A and 101B are overlapped in the same direction, the anti-slip provided on the bottom side of the pallet alone located above contributes to the anti-slip between the pallet and the fork.

The first through-hole 105 is provided for joining the pallets alone, but when used as a pallet alone, the bolts and nuts can be connected only to the second through-hole 107. Good. In addition, in the pallet alone located below, a conventional two-forklift can be used by removing the second support from the left and right ends. Further, the pallet alone is not limited to the joining by bolts and nuts, but can also be joined by rivets or joining by high frequency or heat welding.

FIGS. 10 (a), (b), (c), (d),
(E) and (f) show examples of combinations of pallets alone. Of these, (e) shows a lower part in which forks can be inserted from all sides, and (f) shows an example of a pallet alone in which forks can be inserted from all sides.

Next, another manufacturing method will be described. FIG.
1 (a) and 1 (b) show a plurality of load receiving portions 201, 201 having upper portions extending in the front-rear direction and grooves 203, 20 formed therebetween by bending one resin sheet.
3 shows a manufacturing method using the pallets 205, 205 in the form of irregularities which are alternately repeated in the width direction. According to such a manufacturing method, a large-scale and expensive mold is required, and it is not a general method of molding by pouring a resin into the mold by various methods. A method is provided.

The two pallets 205 and 205 are overlapped in a back-to-back state, and through holes 207 and 20 formed at predetermined positions (three in the front-rear direction) of the groove 203.
7 bolts and nuts and resin rivets 20
9, 209 (the bottom surfaces of the grooves can be bonded together).

FIGS. 12A, 12B and 12C show still another embodiment. In this embodiment, in particular, a feature is provided at the lower part of the pallet. Figures (b) and (c)
In this example, a rib having the same width is provided at a position corresponding to the load receiving portion of the pallet, and an insertion hole through which a fork can be inserted is provided between the ribs. Further, in FIG. 3A, the point that a rib is provided at a position corresponding to the cargo receiving portion of the pallet is the same as in FIGS. 3B and 3C, but the width dimension of the fork insertion holes located at both ends is 125 mm. In order to avoid this, the width dimension of the rib located inside the rib located at both ends is reduced. As a result, the existing two forks can be inserted, so that a conventional forklift can also be used.

As shown in FIG. 12, it is preferable that the vertical cross-sectional shape of the fork is an inverted trapezoid (approximately a draft angle) such that the upper surface width is larger than the lower surface width. As a result of being able to be easily aligned with the groove of the corresponding pallet, the work of lowering the load on the pallet becomes easier.

In order to handle large loads such as containers,
Pallets with widths of 2200 mm and 2000 mm can also be prepared. These pallets can be integrally formed in a state where two pallets having the above-mentioned width dimension of 1100 mm or 1000 mm are arranged side by side. In this case, two pairs of forks corresponding to 1100 mm or 1000 mm may be connected and mounted on the forklift side. The operations performed on these large pallets are the same as for the 1100 mm or 1000 mm pallets.

On the other hand, in order to cope with a small load, any of the above-mentioned pallets can be cut at a position corresponding to the required pallet size to form the pallet required. In this case, as described above, the width of the load receiving portions located at both ends of the final form may be set to 30 to 95 mm.

In the pallet according to the present invention, the length dimension (L) × width dimension (W) (the same applies hereinafter) conforms to International Standard 11
Not only 00 mm x 1100 mm, but also 1000 mm x 1100 mm, which can be
00mm × 1000mm, 800mm × 1200mm,
1000mm × 1000mm, 1000mm × 1100

× 1100mm, 1100mm × 1300mm, 110
It can also be applied to 0 mm x 1400 mm.

For a pallet width of 1300 mm and 1400 mm, for example, a set of peaks and valleys is added inward from both ends of the pallet corresponding to six forks, a fork width of 60 mm and a thickness of 40 mm, and eight forks are added. Both pallets can be used with one forklift.

A forklift corresponding to a pallet width of 1800 mm is, for example, one fork having a fork width of 60 mm.
The number of ridges and troughs of a pallet size corresponding to six forks and a fork width of 60 mm is continuously added from both ends, and the end peaks are set to 30 mm. The common use of fork width for each pallet contributes to the forklift fork production price. Although the width of both ends can be adjusted between 30 mm and 100 mm in any pallet, it is desirable that the width of the pallet be about 50 mm with less damage to the load depending on the state of the load.

Further, the pallet width 900 using a small forklift (maximum load 0.5 to 0.9 t class) is used.
mm.

FIGS. 13A to 13G show examples of the dimensions of the present invention in the various pallets described above. The pallet shown in FIG. 3A corresponds to a pallet having a width of 1100 mm and is made with ten forks having a fork width of 60 mm. And fits. The width of (c) is 13
The 00 mm pallet corresponds to a pallet having a width dimension of 1000 mm, and was created by increasing the fork width to 60 mm and increasing the number of forks from six to eight. This pallet fits on the bed of a G type truck described in the prior art. In the pallet having a width of 1400 mm according to (b), the fork corresponding to the pallet of 1300 mm is moved left and right by 25 mm, and the width of the load receiving portion at both ends is set to 6
It was created by making it 5 mm.

The width of the fork is set to 35 mm so that the fork can be shared with a pallet having a width of 900 mm.

Hereinafter, a method of determining a fork width and a fork interval size that can be shared by a single forklift having a pallet width of 1000 mm, 1100 mm, and 1200 mm and a pallet width of 900 mm for a small forklift will be described. In the following, the width of the pallet is 1000 mm,
The case where the number of forks is six and the width of the fork is 60 mm will be described.

First, the calculation is performed at a half (500 mm) from the center based on a pallet width of 1000 mm.
Second, one central fork is fixed, and two outer forks are 10 width wide.
Move when moving from 00mm pallet to 1100mm. Thus, when using 900 mm and 1000 mm pallets, the forks are in the same position. Third,
The peak width and 6 grooves at the center of the pallet are the same as the dimensions of the 1000 mm pallet. Fourth, the gist of the present invention, 2
The fork width is calculated in consideration of the play of 0 mm to 40 mm.

According to the above calculation method, when the number of forks is 4, 6, 8, 10, 12, 14, and 16, the width of the fork is 100 mm,
65mm ~ 50mm, 45mm ~ 40mm, 35mm ~
30mm, 25mm ~ 20mm, 20mm ~ 15mm,
It is preferable that the thickness be 15 mm to 10 mm.

On the other hand, when the number of forks is four, the width of the pallet is 130 mm for all four grooves.
50mm, 190mm, 100mm, 1

70mm, 35mm, 35mm, 35mm, 35mm,
It can be 35mm, 40mm, 35mm. In the case of 16, the grooves are all 30mm, and the central receiving part is 60m.
m, and all other receiving parts can be 35 mm.

The length of the fork is 1070 mm to 1
It is preferably set to 080 mm. It was found that the corrugated cardboard box had the highest strength at the corners and did not collapse even if the fork supported a position 20 to 30 mm from the corners. Therefore, in this embodiment in which the depth dimensions of the pallets A, B, C, D, E, F, G, and H are 1100 mm, the depth dimension is set to 11 by setting the fork length to the above value.
Even when a cardboard box placed at the front end of a 00 mm pallet is forked with a fork, the distance from the tip of the fork to the corner of the cardboard box can be made 30 mm or less, thereby preventing the cardboard box from being crushed. Since the length of the forklift is set to the minimum length, the turning performance of the forklift can be improved.

Also, in the conventional two-fork, the insertion hole of the fork is large, so that the alignment between the fork and the insertion hole is easy. When a load is placed on the fork, each fork and the groove of the pallet must be aligned, so that the fork and the groove
There is a danger that it may shift or twist in each horizontal direction. If the fork is not aligned with the groove of the pallet, there is a risk that the tip of the fork may damage the load or the pallet. Therefore, careful alignment must be performed, and the work efficiency is reduced.

Therefore, by providing a sensor for detecting the state of alignment between the multi-row fork and the groove of the pallet and a notifying means for notifying the state of alignment, the operability of the forklift can be improved even in the present cargo handling and transporting system. can do. As the sensor, an ultrasonic sensor, an optical sensor, or a CCD camera for imaging the alignment status can be used. In addition, as the notification means, a buzzer that issues an alarm when the position is not aligned, a warning light that lights, or a display that displays this when an imaging unit is used as a sensor can be used. . Furthermore, by performing feedback control on the alignment status detected by these sensors,
The traveling of the forklift itself can also be corrected and controlled.

[0086] By setting the width of the frame supporting the fork in the forklift to have a fixed relationship with the width of the pallet, the alignment between the multi-row fork and the groove of the pallet becomes easy. For example, if the width dimension is 1000
mm, the width of the pallet with a width of 1000 mm matches the outside line of the frame of the forklift, and the width of the frame of the forklift also matches with the inside of the outermost groove of the 1100 mm pallet. Becomes easier.

Further, by providing, for example, two sets of mirror bodies in a forklift instead of the above-mentioned sensor, the alignment with the pallet can be facilitated. Specifically, the forklift body is provided with a first mirror located on a line connecting the tip of the outermost fork and the outer end of the pallet of the multi-row fork, and the first fork mast is provided on the fork mast. The second mirror is provided which receives the reflected light of the mirror and is arranged at a position where the worker can easily recognize the light. If the operator moves the forklift while visually recognizing the second mirror, the operator can easily perform the alignment with the pallet without moving the face sideways. In the above description, two sets of mirrors are used. However, by using, for example, a wide-angle mirror on a convex surface, similar effects can be obtained with one mirror.

Further, when the loaded fork is directly dropped on a conventional flat pallet or floor and pulled out, the vertical pusher plate (P in FIG. 2) provided on the forklift is moved forward and backward with respect to the forklift. Preferably. Here, when placing a load on a multi-row forklift directly on a conventional flat pallet or floor, simply stopping the forklift and pushing out the load from the top of the fork with the pusher plate to unload the load will cause the load to become longer than the length of the fork. As a result of this movement, the load on the side and the bottom surface facing the pusher plate and the collapse of the fork tip portion are liable to occur. Therefore, when unloading, a wall for supporting the load is required.

Therefore, in the present invention, after the forklift is stopped at the position where the forklift is unloaded, the pusher plate is moved forward at the same speed in conjunction with the forklift retreating, so that the load is sequentially dropped from the tip of the fork. It is only necessary for the load to travel half the length of the fork, so that load pain and collapse can be significantly reduced. When the forklift retreats and the pusher plate moves forward as described above, it is desirable that the pusher plate does not move its absolute position regardless of the relative movement of the forklift and the load. Therefore, for example, prior to the forward movement of the pusher plate, the arm can be extended from the lower end of the pusher plate with a jack or the like and fixed to the ground (preferably a suction cup is provided at the lower end of the arm). More specifically, the hydraulic pressure for moving the pusher plate can be easily realized only by diverting the hydraulic pressure for moving the pusher plate to the driving source for the extension operation of the fixed arm, not as the driving source for moving the pusher plate. The arm may be fixed to a fixed rack, truck, or the like instead of the ground.

The amount of retraction of the forklift is measured by measuring the amount of rotation of the forklift in the retreating direction of the tire by the amount of rotation of a metal roller pressed against the tire. it can.

Further, when lowering the load loaded on the fork to a flat field, it is preferable to reduce the thickness of the fork at the tip portion as much as possible (for example, 10 to 15 mm) in order to reduce vibration to the load. In this case, the thickness from the base of the fork to about half of the length is 35
The thickness may be gradually reduced from about half of the length to the tip of the fork. Of course, it goes without saying that the upper surface of the fork is almost horizontal.

If the tip of the fork can be swung horizontally and / or vertically with respect to the base end, it is needless to say that the operability of the forklift is further improved.

The pallet in the present invention is not limited to a pallet that can be independently moved. For example, the pallet may be any one selected from a truck bed, a fixed shelf, a movable shelf, and a movable truck. This also includes the replacement. In this case, it is possible to easily and quickly carry out cargo handling work from a truck or a storage rack, or to a truck or a rack shelf. If the present invention is applied to these storage shelves and movable carts, it is suitable for a cargo handling and transport system in an automatic multi-level warehouse or the like.

In the transition stage from the current system to the present system, it is preferable that a conventional two-fork can be used also in order to ensure the use of a forklift having two forks. For this purpose, in each of the pallets A to F, only the upper part is made uneven so that the multi-row fork is received and only the load is placed or scooped as described above, and the lower part is provided with a hole into which two forks can be inserted. It may be formed.

When a forklift having two forks is used, the width of the fork is set to 100 mm to 60 to 65 mm, so that the load can be accommodated on the fork and the load can be transported without damaging the bottom of the load. I was able to. Further, also in the four-forklift, the fork width is set to 60 to 65 mm, for example, in order to be able to correspond to the pallet shown in FIG. The fixing place can be selected from the six fork positions according to the size of the fork.

However, in order to prevent the pallet according to the present system from being stolen by a conventional forklift having two forks, it is preferable to provide a stopper for closing the insertion hole for the two forks. The stopper can be formed integrally with the pallet in advance, or a separate one can be bolted with an adhesive or an L-shaped fitting.

It is preferable that the pallet has a structure that can be used on both sides in order to reduce the storage space.

In the transport of small lot loads, the current pallets are loaded in the same pallet unit quantity, and the loading of loads of different sizes and quantities is a manual operation, which is inefficient and is excluded from pallet transport. That is the current situation. On the other hand, in the multi-row pallet according to the present invention, it is possible to use a partitioning / load collapse prevention plate which enables mixed loading with other loads. This allows transportation using pallets regardless of the lot size of the load, thereby reducing the cost of transporting small lots and greatly reducing labor and work time.

As such a partitioning / load collapse preventing plate, it is preferable to appropriately prepare a load collapse preventing partitioning plate as shown in FIG. The partition plate has a comb-shaped lower end portion corresponding to the unevenness of the load receiving portion and the groove portion of the pallet, and a plurality of types of loads can be loaded on one pallet, and any one of the partition plates is partitioned by the partition plate. You can also scoop only the cargo.

In each of the embodiments described above, pallets and forks having various widths have been described. However, it is needless to say that those widths including some manufacturing errors are also included in the gist of the present invention. Nor. For example, the width dimension of 495 mm is 500 mm in the present invention.
Are treated according to More specifically, in the embodiment of FIG. 3D, a pallet of a total of 495 mm can be formed by setting the width of the load receiving portion located at the left end portion in the figure to 40 mm. By setting the width dimension of the load receiving portion located on the left side in the drawing to 50 mm in c), a pallet of 510 mm in total can be formed.

[0093]

As described in detail above, according to the present invention, cargo handling can be carried out between a forklift having a multi-row fork and a pallet having a multi-row groove. Various industrial fields, including agricultural products, where it has been the most difficult to rationalize cargo handling and logistics using pallets, such as improving efficiency, significantly reducing manual work in cargo handling such as markets, and eliminating the need for pallet management. In this case, there is an excellent effect that the efficiency of cargo handling and distribution can be significantly improved.

Also, by adopting this system,
In particular, in business establishments in the food-related field, pallets that have been used elsewhere are not used as in the past, so that sanitary control of pallets can be sufficiently performed.

If the width of the load receiving portions located at both ends is smaller than 30 mm (especially 35 mm), the strength of the pallet made of resin (especially waste plastic) when the load is placed is secured. Since it has been proved difficult to carry out the operation, the minimum width dimension of the load receiving portion is set to 35 mm in this embodiment. If the width of the load receiving portions located at both ends in the axial direction is larger than 95 mm (especially 90 mm), when the cargo is loaded so that the corners are located at the outermost ends of the load receiving portions, the groove portions of the fork and the pallet, which will be described later, are used. Considering the play of the fork, it has been found that when this load is picked up with a fork, there is a problem that the amount of protrusion of the cardboard box from the outermost end of the fork becomes large, which causes wrinkles. This is set at 85 mm for safety.
