BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet device which enables efficient work when an article is carried into or out of a storage rack by a forklift truck.

[0002]

2. Description of the Related Art Conventionally, in order to carry an article by a forklift truck and carry it into a storage rack, the article is mounted on a normal pallet, the fork of the forklift truck is inserted into the pallet, and then the fork is used. Lift the pallet, run the forklift truck to carry the goods, then move the forklift truck closer to the storage rack in the direction in which the fork is almost at a right angle to the front edge of the storage rack, and then move the pallet inside the storage rack. The articles are moved to a predetermined position and the pallets are stored in a storage rack. The goods are unloaded from the storage rack in the reverse order.

[0003]

However, in many cases, many storage shelves are juxtaposed in a storage warehouse. At this time, the forklift truck must rotate at a right angle in front of the storage shelves. It is necessary to provide a large space in which the forklift truck, including the pallet portion projecting forward, rotates, on the front side of the storage rack, which reduces the effective storage area in the storage warehouse.

In addition, when carrying an article into a storage shelf,
To correct the storage position shift of the storage rack in the left-right direction, the driver must move the forklift truck backward while holding the pallet once, turn the steering wheel again, and move it forward to move it to the predetermined storage position. As described above, the driver is required to have the skill to orderly arrange the pallets at predetermined positions in the storage rack.

Further, since the operator of the forklift truck cannot see the tip of the pallet or the fork when carrying an article, even a skilled person hits the tip of the pallet or the fork against the storage shelf when changing the direction or carrying the article into the storage shelf. There was a risk that it would be.

An object of the present invention is to easily carry articles into a storage rack without taking a large space in front of the storage rack.
Alternatively, it is to provide a pallet device for transporting articles which can be carried out from a storage rack.

[0007]

In order to achieve the above-mentioned object, the present invention has a first pallet into which a fork of a forklift truck is inserted and conveyed, a loading surface on which an article is placed, and a caster at the bottom. And a second pallet mounted on the first pallet so as to be movable laterally with respect to the traveling direction of the forklift truck by the caster, and the caster of the second pallet is placed on the first pallet. A pallet device for transporting articles is proposed, in which guide means for guiding the casters when the second pallet is moved laterally with respect to the traveling direction of the forklift truck while being rolled, are attached to the first pallet. .

At this time, it is desirable to provide a stopper that prevents the second pallet placed on the first pallet from falling off the first pallet.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described in detail below with reference to the drawings, and the conventional drawbacks will be more specifically clarified with reference to the drawings.

FIG. 1 is a front view of a forklift truck when an article is carried into a storage rack by using the pallet device for conveying articles according to the present invention, as seen from the fork tip side of the forklift truck. FIG. 3 is a perspective view of the pallet device seen from the forklift truck side.

As shown in these figures, the pallet device 1
Is a first pallet 4 to which the pair of forks 3 of the forklift truck 2 is inserted and which is transported by the truck 2.
And a second pallet 5 placed on the first pallet 4.

The second pallet 5 has a mounting surface 7 on which an article 6 is placed, and casters 8 provided at its four corners on the lower portion. Caster 8 is first pallet 4
The second pallet 5 is placed on the first pallet 4 by the casters 8 so as to be movable in the lateral direction with respect to the traveling direction of the forklift truck 2. The operation will be described in detail later.

FIG. 3 is a schematic plan view of FIG. 1, and the reference numerals 9 and 10 in this figure and FIG. 1 are article storage racks, and these racks 9 and 10 are many storage shelves. 1
It has 1, 12, 13, and 14, respectively. The number of storage shelves may be one, or three or more.

Next, a detailed description of the pallet apparatus 1 will be given while explaining the operation when the article 6 is carried by the forklift truck 2 using the pallet apparatus 1 described above and is carried into the storage rack 11 of the rack 9. Clarify the composition.

First, the second pallet 5 is placed on the first pallet 4 at a predetermined position apart from the racks 9 and 10, and the article 6 is loaded on the loading surface 7, but the loading sequence is reversed. May be Next, the fork 3 of the forklift truck 2 is inserted into the first pallet 4, the fork 3 is raised to lift the article 6, and the truck 2 is run to carry the article 6.

At this time, in order to prevent the second pallet 5 placed on the first pallet 4 from falling off from the first pallet 4, a relative movement of both pallets 4, 5 is performed by a stopper configured as a stopper 15. Prevent. As shown in FIG. 2, the stopper 15 is made of an L-shaped bar, and the stopper 15 is inserted into the locking holes 16 and 17 formed in the pallets 4 and 5, respectively. The bent portion 18 of the stopper 15 prevents the stopper 15 from coming out. Stopper 1
Although the number of five may be one, it is desirable to arrange two or more of them. For example, the stoppers 15 are arranged near the four corners of the second pallet 5, and the second pallet 5 is Make it possible to block movements more reliably.

While supporting the first pallet 4 by the forks 3 of the forklift truck 2 as described above, the pallet 4, the second pallet 5 placed on the pallet 4, and the article 6 mounted on the pallet 4 are transported. Then, as shown by the arrow A in FIG. 3, the forklift truck 2 is caused to travel in the passage between the article storage racks 9 and 10 to store the articles 6 in the storage rack 11.
Transport it to near. Then, the fork 3 is lifted so that the upper surface of the first pallet 4 is almost at the same height as the height of the shelf surface 19 of the storage rack 11, and the second pallet 5 is moved to the storage rack 1.
The forklift truck 2 is stopped by moving the forklift truck 2 closer to the front edge 20 of the No. 1 unit. 1 and 3 show the situation at this time.

When performing such a work, the operator of the forklift truck 2 can visually see the front edge 20 of the storage rack 11 and the side edge of the first pallet 4 facing the front edge 20, so that the truck 2 can be easily operated. You can

After the forklift truck 2 is laid side by side on the storage rack 11 as described above, the stopper 15 is pulled out from the locking holes 16 and 17 of both pallets 4 and 5, and then the second pallet 5 travels on the forklift truck 2. The article 6 together with the second pallet 5 is loaded onto the shelf surface 19 of the storage shelf 11 by manually moving the article 6 in the lateral direction, that is, in the direction indicated by the arrow B in FIG.

At this time, the casters 8 roll on the upper surface of the first pallet 4 and the shelf surface 19 of the storage rack 11, so that the second pallet 5 and the article 6 can be easily moved onto the storage rack 11. it can. The state of the articles 6 and the second pallets 5 stored in the storage rack is shown by a chain line in FIG.

After the second pallet 5 and the articles 6 have been stored in the storage rack 11, the above-mentioned stopper 15 or another stopper 115 formed in the same manner as described above is attached to the second pallet 5 as shown in FIG. Locking holes 17 and locking holes 11 formed in the storage rack 11
6, and the second pallet 5 is fixedly locked to the storage rack 11. In this way, the second pallet 5 becomes the storage shelf 1
It is possible to prevent the problem of dropping from 1.

The above is the procedure for loading the article 6 into the storage rack 11. However, when the article on the storage rack 11 is to be carried out, the reverse operation to that described above may be performed.

As described above, when the article 6 is carried into or out of the storage rack 11 by using the illustrated pallet device 1, it is not necessary to secure a large space around the storage rack. This can increase the effective storage area in the storage warehouse in which the racks 9 and 10 are arranged.

Conventionally, as shown in FIG. 8, an article 6a is mounted on one pallet 4a, a fork 3a of a forklift truck 2a is inserted into the pallet 4a, and the pallet 4a is transported to the storage rack 11a. Therefore, a large space S1 was required in front of the rack 9a. That is, conventionally, the forklift truck 2a that has traveled in the direction of arrow A is rotated in front of the storage shelf 11a as shown by arrow C, and the fork 3a is stored in the storage shelf 11a.
Therefore, it is necessary to make a large space S1 for rotating the forklift truck 2a.

On the other hand, if the pallet device 1 of this example is used, as described above, the forklift truck 2 is advanced in the direction indicated by the arrow A in FIG. 3, and then the second pallet 5 is moved in the direction indicated by the arrow B. Just move it, track 2
Need not be rotated as in the past. Therefore, there is no need for a space for rotating the truck 2 in front of the storage rack 11, and it is sufficient if there is a narrow space S in which the forklift truck 2 can travel.

Moreover, since the driver only has to move the forklift truck 2 substantially straight along the storage rack 11, the operation thereof is extremely simple and there is no risk of the fork 3 hitting the storage rack 11.

Further, when the first pallet 4 is brought close to the storage rack 11, the front edge 20 of the storage rack 11 and the side edge of the first pallet 4 can be visually observed, which also makes it possible to easily operate the truck. .

The number of casters 8 attached to the second pallet 5 may be appropriately set according to the weight of the article 6 on the second pallet 5, and is not necessarily four as in the illustrated embodiment. . Further, at least the upper surface of the first pallet 4 on which the casters 8 roll is formed in a flat planar shape so that the casters 8 can smoothly rotate when the casters 8 roll on the first pallet 4. Is desirable. Further, as the first pallet 4, an ordinary pallet that has been commonly used in the past can be used, and its form is
As long as it does not hinder the rolling of the casters 8, it may be a drain-shaped pallet with a gap, or a pallet in which a part or the whole of its upper part is a flat plate.

The dimensions of the first pallet 4 are set to the second pallet 5
When it is made larger, the work of bringing the side edge portion of the first pallet 4 closer to the front edge 20 of the storage rack 11 becomes easier.

When the above-mentioned stoppers 15, 115 are not used, the short bent portion 18 on the tip side thereof is provided with locking holes 17, 116 for the second pallet 5 and storage rack 11 as shown in FIG.
If you insert it in, the stopper will not get in the way. If the stopper 15 and the second pallet 5 are connected by a chain 21 or the like, the stopper 15 can be prevented from being lost. The same applies to the stopper 115.

When the second pallet 5 is placed on the first pallet 4 or the storage rack 11 by using the caster 8 having the rotation stopping mechanism instead of using the above-mentioned stopper, the caster 8
May be prevented from rotating.

Further, stoppers other than the stoppers and the rotation stopping mechanism as described above can be appropriately used. For example, as shown in FIGS. 5 and 6, when the second pallet is moved, the first pallet 4 on the side where the second pallet passes is moved. A stopper made of a plate-shaped frame body 23 may be provided on the side surface 22. In this frame 23,
A pair of first guide slots 24 and a second guide slot 25 connected thereto are formed. On the other hand, on the side surface 22 of the first pallet 4, the guide locks 24, 2 are provided.
A nail 26 having a head with a diameter larger than the width of 5 is driven in and projected.

When the second pallet 5 is placed on the first pallet 4, the nail 26 is passed through the second guide slot 25 as shown in FIG. The casters 8 of the second pallet 5 are prevented from falling off by projecting above the upper surface.

When the second pallet 5 is moved from the first pallet 4 to the storage pallet 11 or, conversely, the second pallet 5 is moved from the storage ledge 11 onto the first pallet 4, a frame as shown in FIG. The body 23 is moved so that the nail 26 is passed through the first guide slot 24, thereby lowering the frame body 23 at the same level as or lower than the upper surface of the first pallet 4 so that the casters 8 can pass therethrough without trouble. To

On the side surface of the first pallet 4 which faces the frame body 23 shown in FIGS. 5 and 6, a second frame body which is supported so as to be vertically movable just like the frame body 23 (see FIG. A stopper made of (not shown) is provided and the first pallet 4
A stopper composed of immovable frames 27 and 28 is fixed to the other two side surfaces of the second pallet to prevent the second pallet 5 from falling off the first pallet 4. Further, by lowering the second frame body downward, the second pallet 5 can be moved from the second frame body side.

The materials of the first and second pallets 4, 5 and the frames 23, 27, 28 may be any suitable materials such as wood, hard synthetic resin or metal.

In the pallet apparatus described above, the guide means not shown in FIGS. 1 to 6 is attached to the first pallet 4. This guide means transfers the second pallet 5 to the storage rack 11 or from the storage rack 11 to the first pallet 4.
When it is moved to, the casters 8 of the second pallet 5 are guided, and an example thereof is shown in FIG. The guide means shown here comprises a pair of guide rails 29 on which the casters roll, and the rails 29 are fixed to the upper surface of the first pallet 4. When the second pallet 5 is moved in the lateral direction B with respect to the traveling direction of the forklift truck 2 while rolling the casters 8 of the second pallet 5 on the first pallet 4 as described above, , Is guided by a guide means composed of a guide rail 29 attached to the first pallet 4. As a result, the second caster 5
Can be moved reliably.

Instead of the guide rail 29 shown in FIG. 7,
A rail or the like having an L-shaped cross section can also be used.

When the guide rails 29 as described above are provided, as shown in FIG. 7, a breaker type stopper 30 rotatable in the direction of arrow D is provided on the first pallet 4 near the end of each guide rail 29. By pivotally attaching the guide rail 29 to the first pallet 4 by blocking the guide rail 29 with the stopper 30,
It is possible to prevent the casters 8 of the second pallet 5 placed on the top from coming off from the guide rails 29. If the stopper 30 is rotated to the position shown in FIG. 7 to release the blocking state, the caster 8 can be freely rolled on the guide rail 29 and the second pallet 5 can be moved.

Guide rails and stoppers similar to the guide rails 29 and stoppers 30 shown in FIG.
It is also provided on the first shelving surface 19 so that the second pallet 5 can be reliably guided in the storage shelf 11 when the second pallet 5 is moved, and the second pallet 5 can be fixedly held in the storage shelf 11 when storing articles. It can also be configured.

[0041]

According to the pallet device of the first aspect, the second pallet loaded with articles can be moved laterally with respect to the traveling direction of the forklift truck, so that the forklift truck is located in front of the storage rack. Even if there is not a large space for rotating, the article can be carried in or out of the storage shelf, and the effective storage area in the storage warehouse can be expanded. Further, by simply moving the second pallet having the casters laterally for a short distance, the pallet is moved from the first pallet to the storage rack.
It can also be transferred from the storage rack to the first pallet. Moreover, the second pallet has a storage function for articles similar to the conventional pallet, and the second pallet can be placed on the first pallet in a stable state to safely transport the articles.

Further, when loading or unloading an article, the forklift truck only has to move substantially straight along the storage rack, and when the first pallet is brought close to the storage rack,
Since the driver can see the first pallet approaching the storage rack, the forklift truck can be easily operated,
You can prevent problems such as hitting the fork against the storage shelf.

Further, while rolling the casters of the second pallet on the first pallet, the guide means for guiding the casters when moving the second pallet laterally with respect to the traveling direction of the forklift truck is provided. Since it is attached to one pallet, the second pallet can be reliably moved in the predetermined direction, and the work can be further simplified.

According to the pallet device of the second aspect,
The problem that the second pallet falls off the first pallet can be reliably prevented.
