[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pallet device that enables efficient work when an article is carried into or out of a storage rack by a forklift truck.

[0002]

[Prior art]

 Conventionally, in order to transport an article by a forklift truck and carry it into a storage shelf, the article is mounted on a normal pallet, the fork of the forklift truck is inserted into the pallet, and then the pallet is loaded by the fork. Lift and drive the forklift truck to carry the goods, then move the forklift truck closer to the storage rack in the direction in which its fork is almost at a right angle to the front edge of the storage rack, and then place the pallet in the storage rack at a predetermined position. The items are moved to the position and the pallets are stored in the storage shelves. The goods are unloaded from the storage rack in the reverse order.

[0003]

[Problems to be solved by the device]

 However, many storage shelves are often installed side by side in the storage warehouse, and at this time the forklift truck must rotate at a right angle in front of the storage shelves, so the pallet portion protruding forward from the vehicle body was included. A large space for the forklift truck to rotate has to be provided in front of the storage shelves, thus reducing the effective storage area in the storage warehouse.

In order to correct the misalignment of the storage shelves in the left-right direction when carrying articles into the storage shelves, the driver retracts the forklift truck with the pallet once lifted and turns the steering wheel again. It has to be advanced again and moved over its intended storage position. As described above, the operator 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 an expert can hit the tip of the forklift on 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 provide a pallet device for transporting articles which can easily carry articles in or out of the storage rack without taking a large space in front of the storage rack. It is in.

[0007]

[Means for Solving the Problems]

 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 transported, a mounting surface on which an article is placed, and a caster at a lower portion. 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.

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.

A guide means for guiding the caster of the second pallet while rolling the caster on the first pallet and moving the second pallet laterally with respect to the traveling direction of the forklift truck. Is advantageously attached to the first pallet.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings, and at the same time, conventional drawbacks will be more specifically clarified with reference to the drawings.

FIG. 1 is a front view of a forklift truck when a product is carried into a storage rack by using a pallet device for carrying goods according to the present invention, as seen from the forklift truck front end side. FIG. 2 is a perspective view of the pallet device as viewed from the forklift truck side.

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

The second pallet 5 has a mounting surface 7 on which the article 6 is placed, and casters 8 provided at its four corners at the lower portion of the second pallet 5. The casters 8 are placed on the upper surface of the first pallet 4, and the second pallets 5 are placed on the first pallet 4 by these casters 8 so as to be movable laterally with respect to the traveling direction of the forklift truck 2. It is placed. 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 store a large number of storages. It has shelves 11, 12, 13, and 14, respectively. The number of storage shelves may be one, or three or more.

Next, using the pallet apparatus 1 described above, an operation for transporting the article 6 by the forklift truck 2 and loading the article 6 into the storage rack 11 of the rack 9 will be described, and a more detailed description of the pallet apparatus 1 will be given. Clarify the composition.

First, the second pallet 5 is placed on the first pallet 4 at a predetermined position distant from the racks 9 and 10, and the article 6 is loaded on the loading surface 7 thereof. May be reversed. Then, the fork 3 of the forklift truck 2 is inserted into the first pallet 4, the fork 3 is lifted 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 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. The number of the stoppers 15 may be one, but it is desirable to dispose them at two or more places. For example, the stoppers 15 are arranged near the four corners of the second pallet 5, respectively. , So that the movement of the second pallet 5 can be prevented 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, and the article 6 is transported to the vicinity of the storage shelf 11. Then, the fork 3 is lifted so that the upper surface of the first pallet 4 is almost at the same height as the shelf surface 19 of the storage shelf 11, so that the second pallet 5 contacts the front edge 20 of the storage shelf 11. Approach and stop the forklift truck 2. 1 and 3 show the situation at this time.

When performing such a work, the driver 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 is run on the forklift truck 2. The article 6 together with the second pallet 5 is carried onto the shelf surface 19 of the storage shelf 11 by manually moving the article 6 in the direction lateral to the 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 shelves is shown by a chain line in FIG.

After the second pallet 5 and the article 6 are stored in the storage rack 11, the above-mentioned stopper 15 or another stopper 115 formed in the same manner as described above is used as shown in FIG. The second pallet 5 is fixedly locked to the storage shelf 11 by inserting the second pallet 5 into the locking hole 17 and the locking hole 116 formed in the storage shelf 11. In this way, it is possible to prevent the problem that the second pallet 5 falls off the storage rack 11.

The above is the procedure for carrying the article 6 into the storage shelf 11, but when carrying out the article on the storage shelf 11, the reverse operation to the above may be performed.

As described above, when the article 6 is carried in or out of the storage shelf 11 using the pallet apparatus 1 according to the present invention, it is not necessary to secure a large space around the storage shelf. . As a result, the effective storage area in the storage warehouse where the racks 9 and 10 are arranged can be expanded.

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 fork lift truck 2a traveling in the direction of arrow A must be rotated in front of the storage rack 11a as shown by arrow C, and the fork 3a must be opposed to the storage rack 11a. It was necessary to make a large space S1 for rotating the shift truck 2a.

On the other hand, when the pallet device 1 according to the present invention 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. Need only be moved in the direction of arrow B, and the track 2 need not be rotated as in the conventional case. Therefore, there is no need for a space for rotating the truck 2 in front of the storage rack 11, and a small space S in which the forklift truck 2 can travel is sufficient.

Moreover, since the driver only has to drive 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. Become.

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. . Also, 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 rotate smoothly when rolling on the first pallets 4. Is desirable. Further, as the first pallet 4, an ordinary pallet that has been generally used in the past can be used. As long as it does not hinder the rolling of the casters 8, the pallet is in the form of a sludge with a gap. It may be a pallet or a pallet in which a part or the whole of the upper part thereof is a flat plate.

If the size of the first pallet 4 is made larger than that of the second pallet 5, 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 fitted into the locking holes 17, 116 of the second pallet 5 and the storage rack 11 as shown in FIG. If it is inserted, 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 palette 5 is placed on the first pallet 4 or the storage shelf 11 by using the caster 8 having the rotation stopping mechanism instead of using the above-mentioned stopper, the rotation of the caster 8 is prevented. You may do it.

Further, a stopper other than the stopper as described above can be used as appropriate, and for example, as shown in FIGS. 5 and 6, when moving the pallet, a plate is formed on the side surface 22 of the first pallet 4 on the side through which the pallet moves. It is also possible to provide a stopper composed of the frame body 23. The frame 23 has a pair of first guide slots 24 and a second guide slot 25 connected to the first guide slots 24. On the other hand, on the side surface 22 of the first pallet 4, a nail 26 having a head having a diameter larger than the width of the guide locks 24, 25 is driven 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 rack 11, or conversely, the second pallet 5 is moved from the storage rack 11 onto the first pallet 4, the frame is moved as shown in FIG. The body 23 is moved to pass the nail 26 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, through which the casters 8 pass without hindrance. It can be so.

A second frame body (FIG. 5 and FIG. 6) supported on the side surface of the first pallet 4 facing the frame body 23 so as to be movable up and down just like the frame body 23 (see FIG. A stopper made of (not shown) is provided, and stoppers made of immovable frames 27 and 28 are fixed to the other two side surfaces of the first pallet 4 so that the second pallet 5 can be removed from the first pallet 4. Prevent. By lowering the second frame body downward, the second pallet 5 can be moved from the second frame body side.

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

A guide means for guiding the casters 8 of the second pallet 5 when moving the second pallet 5 to the storage rack 11 or from the storage rack 11 to the first pallet 4 can be provided. An example is shown below. 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 casters 8 of the second pallet 5 are rolled on the first pallet 4 as described above and the second pallet 5 is moved in the lateral direction B with respect to the traveling direction of the forklift truck 2, the casters 8 are moved. , Is guided by a guide rail 29 attached to the first pallet 4. As a result, the second caster 5 can be reliably moved.

Instead of the guide rail 29 shown in FIG. 7, it is also possible to use a rail having an L-shaped cross section.

When the guide rails 29 as described above are provided, as shown in FIG. 7, the first pallet is provided with a breaker type stopper 30 which is rotatable in the direction of arrow D near the end of each guide rail 29. The caster 8 of the second pallet 5 placed on the first pallet 4 is prevented from coming off from the guide rail 29 by pivotally connecting the guide rail 29 to the guide rail 29 by the stopper 30. be able to. 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. 8 are also provided on the shelf surface 19 of the storage shelf 11, and when the second pallet 5 is moved, these are installed. In addition, the second pallet 5 can be securely held on the storage rack 11 when the article is stored.

[0042]

[Effect of device]

 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 rotated in front of the storage rack. Even if there is not a large space for storage, articles can be carried in or out of the storage rack, and the effective storage area in the storage warehouse can be expanded. In addition, the second pallet having the casters can be moved from the first pallet to the storage rack or from the storage rack to the first pallet simply by moving the second pallet laterally for a short distance. Moreover, the second pallet has a storage function for articles, like the conventional pallets, 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 almost straight along the storage rack, and when the first pallet approaches the storage rack, the driver needs to move the first pallet to the storage rack. As it is visible, the forklift truck can be easily operated and the trouble of hitting the fork on the storage rack can be prevented.

According to the pallet device of the second aspect, it is possible to reliably prevent the problem that the second pallet falls off the first pallet.

According to the pallet device of the third aspect, the second pallet can be reliably moved in the predetermined direction, and the work can be further simplified.
