Description

The present invention relates to a vehicle tire transport system capable of loading and unloading a truck or the like into a loading platform (box-shaped loading platform) using a unique tire loading pallet, even by an elderly person or a woman. In particular, by using the tire loading pallet in a special storage warehouse, even the workers in the storage warehouse, which had been manually operated until now, can be completely eliminated, and car tires can provide safe and secure tire loading work. Regarding the transport system.

Conventionally, there has been no dedicated transport business for transporting tires on the truck bed (box-type carrier). This need arises because of the existence of tire changes. In other words, there were summer tires (which also serve as spring and autumn) and winter tires for snow, and it was necessary to change them.

In the housing situation, there is a space at home where you can store one of the tires for summer and winter in the countryside, but in urban areas, etc., a storage service that allows you to store the tires in another place when you change tires. Is increasing year by year. In this case, four tires are set. Hereinafter, it is also referred to as a set of four tires.

At the time of changing the tires, a plurality of tires are appropriately placed on an appropriate pallet by a worker or a clerk of a car dealer (a car dealer such as a new car or a used car) or a car accessory store (car shop). It is transported to a storage warehouse for appropriate tires.

Patent Document 1 (Japanese Unexamined Patent Publication No. 9-30648) is disclosed as a plurality of tire transport pallets. In Patent Document 1, a large number of tires can be stacked flat and stacked, but this tire is a completed tire, which is different from a case where tires can be simply loaded and unloaded on a truck or the like.

Further, in Patent Document 2 (Japanese Patent Laid-Open No. 6-293371). It is a pallet for loading a large number of tires vertically, but even if tires can be loaded and unloaded on trucks under this condition, tires can be loaded and unloaded in a warehouse dedicated to tires without the need for manpower. It is unclear if it can be unloaded.

In addition, even if it is a domestic tire manufacturer, it is carried by truck etc. even if it can be used with a forklift in a storage warehouse where a large number of ordinary tires can be stored, not in a new tire manufacturing factory etc. The tires that have been made, especially a set of four tires, are not in a state where they can be stored without human intervention.

INNOLIFT (known on the net as an innolift) is often used to transport multiple tires. This transportation of multiple tires has the advantage that even one elderly person or a woman can load and unload flat-stacked tires on the car carrier, but most of the currently known tire storage warehouses are warehouses. The current situation is that they are often manually stacked on their own pallets. Many of the original pallets can use a forklift.

It is easy to manually stack and unload tires in a storage warehouse, but one tire weighs about 20 to 30 kg. Even for adolescent boys, it is almost impossible to continue with one or two hours of continuous work. Moreover, when it comes to workers in the storage warehouse, they are generally middle-aged and over 60 years old boys. The majority of these people are currently suffering from back pain or poor physical condition.

By the way, in Europe, in a tire storage warehouse, a device or mechanism for lifting a set of four tires by an elevator of a type that moves up and down with a rod-shaped fork exists as a conventional technique. However, with known fork pallets, it is not possible to use an elevator of the type that raises and lowers with the rod-shaped fork.

Japanese Unexamined Patent Publication No. 9-30648 Japanese Unexamined Patent Publication No. 6-293371

However, the problem (technical problem or purpose, etc.) to be solved by the present invention is to load (called stacking) into and unload a truck's loading platform (box-shaped loading platform) by using a unique tire loading pallet. However, it is possible for one elderly person or a woman, and by using a special storage warehouse for tire loading via the tire loading pallet, even the workers in the storage warehouse, which had been manually operated until now, are completely manual. It is to realize the provision of a vehicle tire transport system for safe and secure tire loading work that can be made unnecessary.

Therefore, as a result of diligent research to solve the above problems, the inventor has applied the invention of claim 1 to the lower surface of the square main plate, the end rod-shaped legs on both sides in a river shape, and the central rod-shaped leg. Are fixed to the upper surface of the main plate, and the upper surface end pedestal piece and the upper surface intermediate pedestal piece, which face the same direction as the respective legs and have the same shape and are closer to both sides, are fixed to each other and are stacked upward. In addition, the upper surface end pedestal piece is arranged on the end rod-shaped leg portion, and the upper surface intermediate pedestal piece is arranged so as not to overlap the central rod-shaped leg portion. A set of four flat-stacked tires is placed in a two-tiered stack, and a plurality of pallets of the two-tiered tire set are mounted on a van type or a truck bed with a first lifter. 1 Lifter is also placed and transported to a storage warehouse at a desired position, and at the storage warehouse location, the tire 4-piece set 2-tier pallet is loaded and unloaded at the storage warehouse location, and the tire 4-piece set 1 is loaded and unloaded. The second lifter provided in the storage warehouse with only the four-tire set one-tier stack placed directly on the four-tire set one-tier pallet under this condition after rearranging the tires into a stack pallet. The above-mentioned problems have been solved by adopting a vehicle tire transport system characterized in that the tires can be directly placed on both claws and stored at the storage warehouse.

According to the invention of claim 2, in the vehicle tire transport system according to claim 1, the upper surface intermediate pedestal pieces are fixed to the upper side of the main plate as one or two pieces, and even if they are stacked upward, one piece is used. Alternatively, the two upper intermediate pedestal pieces are configured as a tire loading pallet arranged so as not to overlap each other on the central rod-shaped leg portion, thereby forming a vehicle tire transport system. This is a solution to the above problem.

In the invention of claim 1, the elderly or women can load and unload a set of four tires in two stages not only on a truck or the like, but also in a storage warehouse dedicated to a large number of tires without any manual labor. Even so, there is an advantage that a vehicle tire transport system can be provided safely and securely. In addition, the central rod-shaped leg on the lower side of the main plate is removed, and only the end rod-shaped legs on both sides are fixed, which simplifies the tire loading pallet and still provides the strength of the main plate 1. By ensuring that, the vehicle tire transport system can be improved.

In the invention of claim 2, the reinforcing function can be increased by providing the central rod-shaped leg portion on the lower side of the main plate, and the same effect as that of the invention of claim 1 can be obtained.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2. In particular, as shown in FIGS. 1A and 1B, the main plate has a substantially square shape. The end rod-shaped legs 2 and 2 and the central rod-shaped legs 3 on both sides are fixed to the lower surface of the main plate 1 in a river shape, respectively, and the upper surface of the main plate 1 also faces in the same direction as the legs. It has the same shape and is configured by fixing the upper surface end pedestal pieces 4 and 4 and the upper surface intermediate pedestal pieces 5 and 5 to both sides.

Although the main plate 1 has a square shape, it is included in the concept of a square shape even if it is a genuine square or slightly different by a few centimeters. Further, the end rod-shaped legs 2 and 2 and the central rod-shaped leg 3 are formed on the back surface of the main plate 1 to have a length equivalent to the length of the main plate 1 [see FIG. 1 (C)]. Further, the dimensional relationship of the tire loading pallet P will be described later with respect to the tire diameter. Further, the tire loading pallet P is often simply referred to as a "pallet" or a "pallet P".

In particular, when the pallets P are stacked upward at the same position, the upper surface end pedestal pieces 4 and 4 are on the end rod-shaped legs 2, and the upper surface intermediate pedestal pieces 5 and 5 are the central rod-shaped legs. They are arranged so that they do not overlap (do not abut). Specifically, a distance α is formed between the inner side surface of the end rod-shaped leg 2 and the outer surface of the upper surface end pedestal piece 4. For example, it is about several millimeters to about 10 cm. Further, the distance between the upper surface intermediate pedestal pieces 5 and 5 is about 15 cm, and it is sufficient that the central rod-shaped leg portion 3 exists at this intermediate position, and if they do not overlap (do not abut), the dimensions are such. Not limited.

Further, the upper surface end pedestal piece 4 is arranged on the end rod-shaped leg portion 2, and the upper surface intermediate pedestal pieces 5 and 5 are arranged so as not to overlap (contact) with the central rod-shaped leg portion 3, respectively. More specifically, when the upper and lower pallets P and P are overlapped, the upper surface end pedestal piece 4 has a gap between the end rod-shaped leg 2 and the central rod-shaped leg 3 of the upper pallet P. It is formed so as to be located within 23 [see FIG. 1 (B)].

In particular, the reason why the upper surface end pedestal pieces 4 and 4 are widened so as not to overlap each other is to stabilize the tire loading. Further, when the upper and lower pallets P and P are overlapped, the central rod-shaped leg portion 3 is configured to exist in the gap portion 5a between the upper surface intermediate pedestal pieces 5 and 5 [FIG. 1]. See (B)].

FIG. 1E is another embodiment of the pallet P, in which the upper surface intermediate pedestal piece 5 is one. As a condition in this case, specifically, a distance β is formed between the inner side surface of any one of the central rod-shaped legs 3 and the inner side surface of any one of the facing upper surface intermediate pedestal pieces 5. For example, it is about several millimeters to about ten and several centimeters. This number is not always limited.

In particular, when the main plate 1 is made of a strong plate material, the pallet P is composed of only the end rod-shaped legs 2 and 2 on both sides, excluding the central rod-shaped leg portion 3. There is also another embodiment (not shown). That is, the pallet P is not provided with the central rod-shaped leg portion 3. In this case, the distance α between the upper surface end pedestal piece 4 and the end rod-shaped leg 2 on the upper side of the main plate 1 and the number (1 or 2) of the upper surface intermediate pedestal pieces 5 are shown in FIGS. 1 and 1. It is the same as the embodiment as shown in FIG. 2, and the conditions when the upper and lower pallets P and P are overlapped are also the same.

Further, by adopting another embodiment of the pallet P [see FIG. 1 (E)], not only the unit price can be reduced, but also the four-tire set M can be reliably placed on the pallet P, which is functional. It also has a sufficient effect. In the following description, the pallet P having the configuration of the first embodiment, in which the upper surface intermediate pedestal piece 5 is provided with two pieces and the central rod-shaped leg portion 3 is also provided, will be described.

A set of four tires M is placed on the upper side of the pallet P, but it is necessary to hang a belt 7 on the box-shaped loading platform K of the truck in order to prevent it from tipping over. It is also important that the belt 7 is cross-hung when the four-tire set M is placed and viewed in a plane.

In order for the locking portion 7a at the end of the belt 7 to be securely locked, a locking tool 6 for locking is required. As shown in FIG. 2B, the locking tool 6 is provided with a screw rod 6b on a substantially V-shaped tool main body 6a. The screw rod 6b is inserted from one side, and the screw portion at the tip is screwed into the tool body 6a and fixed to the four corner portions Q of the pallet P.

Further, as shown in FIG. 2C, the woven pallet P may be fixed to the four corners Q of the woven pallet P in a substantially Δ shape with a wire or a wire. In any case, when the four tire set M is placed on the pallet P and the truck is moved, as shown in FIG. 2D, the locking tool 6 is engaged with the end portion of the belt 7. The stop portion 7a is locked so that the load does not collapse during transportation.

Further, even if the locking tool 6 is not provided, if the locking portion 7a at the end of the belt 7 can be locked so as to bite into the back surface of the main plate 1 at the corner Q of the pallet P, the locking tool 6 is not necessarily do not need. This is because the main plate 1 is often made of wood.

Here, an outline of a vehicle tire transport system using the pallet P will be described with reference to FIG. FIG. 3A is a simplified diagram showing a working state in which a set of four tires is placed, and is purchased or purchased on the pallet P by a clerk or a worker of a car dealer / car shop of a new car or a used car. A set of four tires M, which has been replaced with tires for winter or summer, is placed. In this case, the four-tire set M is generally placed on the pallet P by a store clerk or a worker manually.

Then, a plurality of the (one-tiered) pallets P with a set of four tires M are loaded by truck [see FIG. 3 (B)] and moved to an appropriate storage warehouse [see FIG. 3 (C)]. At the location, only the 4-tire set M is stored and stored in the storage warehouse, and after being placed as the 4-tire set M by the clerk or worker of the car dealer / car shop, it is loaded onto the truck. The loading and unloading, loading and unloading of the tire rack 9 in the storage warehouse, and loading and unloading all have a great effect of being able to work without manpower.

In particular, two main points of the vehicle tire transport system of the present invention will be described through the work. First, as shown in FIGS. 4A and 4B, the work is to use the lower side of the pallet P. That is, the claws 81a and 81a of the first lifter 81 are inserted into the lower surface side of the main plate 1 of the pallet P with the four-tire set M, and in this state, one stack of the pallets P with the four-tire set M is stacked on the truck. It can be placed on the box-type carrier K [see FIG. 7 (A)], or carried to the back side on the box-type carrier K of the truck [see FIG. 7 (B)].

When stacking (loading) a pallet P with a set of four tires M on a box-shaped loading platform K of a truck, in consideration of transport efficiency, two-tier stacking is performed as shown in FIGS. 8A and 8B. In many cases. In FIGS. 8A and 8B, the band 7 is not shown on the pallet P with the 4-tire set M in order to avoid complication of the drawing, but in reality, the figure is shown. It is transported in a state like 9.

Further, as shown in FIG. 7B, it is of course possible to transport the four-tire set M by the one-stage stacking pallet P. In particular, even in the case of stacking four tire sets M in one stack [see FIG. 7 (B)] and stacking two tires [see FIG. 8 (B)], in the transport system of the present invention, the first lifter 81 is also a truck box-type loading platform K. The truck loading work is completed, and the truck loading work is completed, and the truck is moved to a storage warehouse at another location. At this time, the first lifter 81 is also loaded and moved at the same time. In the case of one-tier stacking of a set of four tires M, about two flat-stacked tires may be stacked and transported via the pallet P on the one-tier stack.

The structures shown in FIGS. 6A to 6C show the relationship between the tires of the four-tire set M and the pallet P. Specifically, the length L of one side of the square main plate 1 is the diameter D of the tire.
D> L
And
Furthermore, the four corners Q of the pallet are always under the exposed state.
Also, as for the size relationship,
D> Q
Will be.

The diameter D of the tire is larger than the length L of one side of the square main plate 1. That is, when D> L, as shown in FIG. 6C, when the pallet P with a set of four tires M is placed on the box-shaped loading platform K of the truck, even if it vibrates during the operation of the truck. , The wall surface of the box-shaped loading platform K of the truck always hits the outermost surface of the tire, the others do not hit, it can be done without damaging the pallet P, noise can be avoided for the truck driver, and safe driving is also possible. Can be provided.

In this way, the pallet P with the set of four tires M is moved by truck to a desired storage warehouse and dropped onto the ground at the storage warehouse location. Specifically, the four-tire set M is sequentially loaded in either one-tier stacking [FIGS. 7 (B) to 7 (A)] or two-tier stacking [FIG. 8 (B) to 8 (A)]. On the contrary, the first lifter 81 is used to lower the pallet P with a set of four tires M onto the ground of the storage warehouse. In this way, everything is dropped onto the ground at the storage warehouse. This completes the role of the first lifter 81.

Next, the second main part of the vehicle tire transport system of the present invention will be described through the work. This will be work in the storage warehouse. First, the claws 82a and 82a of the second lifter 82 are inserted into the upper side of the main plate 1 of the pallet P with a set of four tires M [see FIG. 5 (A)], and the claws of the second lifter 82 are used. Insertion of 82a and 82a is completed [see FIG. 5B]. As a result, only the four-tire set M is moved. That is, the pallet P is removed.

Then, as shown in FIG. 11, the work of mounting the four tire set M on the desired floor position of the tire rack 9 is performed at the claw portions 82a and 82a of the second lifter 82. To do this, first, as shown in FIG. 10 (A), the four-tire set M is raised at the claw portions 82a, 82a to the position of the desired number of floors, and then as shown in FIG. 10 (B). The claw portions 82a, 82a are inserted between the rod-shaped portions 9a, 9a, 9a of the tire rack 9. Then, as shown in FIG. 10C, the four tire set M is placed on the rod-shaped portions 9a, 9a, 9a of the tire rack 9 and completed.
This completes the work of the second lifter 82, and further stores or collects the pallet P as appropriate.

In the work in this storage warehouse, as shown in FIG. 12, the tire four-piece set M placed at the desired floor position of the tire rack 9 is not all manually operated, but the claw portions 82a, 82a of the second lifter 82 are used. At, load and unload work is done. At this time, when loading and unloading the four-tire set M, the tires are placed on the pallet P again. Then, the box-shaped loading platform K of the truck is operated by the claw portions 81a and 81a of the first lifter 81. This is done in reverse order in the drawings as in FIGS. 7 and 8. By doing so, the effect is that even elderly people and women (one person) can easily transport and manage the warehouse of the four-tire set M without any human intervention.

In particular, in a management warehouse where a set of four tires M is stored, it is necessary to select and take out a desired set of four tires M from a large number of four tire sets M, M, .... It is possible to efficiently perform the picking work in the controlled warehouse by using the above-mentioned second lifter 82. In this case as well, elderly people and women can do it.

As described above, in the vehicle tire transport system of the present invention, in particular, by using the tire loading pallet P (pallet P), the manual loading and unloading of tires in the storage warehouse is completely eliminated, so-called villainy. With the goal of improving the workplace, we provide a car tire transport system that makes it easy for elderly people and women to transport and move a set of four tires by truck, in a series of transport work to the storage warehouse. can. Further, although the set of four tires is described as tires for passenger cars and van types, truck tires may also be included in some cases.
