Description

Combined pallet structure

Technical field

The invention relates to a pallet structure, in particular to a pallet structure formed by combining linear production.

Background technique

The pallet is a common auxiliary carrier for warehousing and logistics. It can be used with a stacker to move or stack goods; the most common pallet is a wooden pallet, which is nailed using several wooden boards to form a single-sided or A structure that carries items on both sides. However, wooden pallets have several inherent problems. First, the cost of wooden boards is not low. Although they can be reused, they have poor impact resistance and moisture resistance, and they are heavy. The cost of transportation will increase significantly.

In addition to the common wooden pallets, various pallets of different materials have also been developed, such as metal pallets, corrugated pallets, plastic pallets, or composite gluing pallets, but they are not too heavy. The manufacturing cost is too high, otherwise the reuse rate is too low, and it is currently difficult to completely replace the wooden pallet.

Among them, the potential of plastic pallets is greater, because the cost of plastic materials is lower than other materials, and the plasticity is large, it is easy to clean, the weight is light, and it is moisture-proof; therefore, it is the most important replacement material. However, the biggest problem with plastic pallets is that in order to achieve sufficient strength to form pallets, plastic pallets have a more complex structural design to compensate for the rigidity of the material itself; while most plastics use injection molding, which is complicated The design of the structure also makes its mold development cost high, and the injection (manufacturing) cost and time are also high. Therefore, it is difficult to universally apply and replace the traditional wooden pallet.

In order to solve the above problems, there is an urgent need to propose a new pallet structure to replace the existing wooden pallet and overcome the related problems derived from it.

Summary of the invention

In view of this, the present invention proposes a combined pallet structure, which can solve the above-mentioned lack of conventional technology, and can be manufactured using a linear production manufacturing process, which can greatly reduce manufacturing and production costs.

Another object of the present invention is to provide a combined pallet structure, which has a simple structure, light weight and high specific strength, and can replace the existing pallets of various materials.

The combined pallet structure disclosed in the present invention includes a bottom plate and a panel. The bottom plate and the panel are all structures that can be linearly produced, and can be manufactured in a simple and low-cost manner such as extrusion, extrusion, and extraction. The bottom plate The panel has a plurality of reinforcing ribs and is joined so that the reinforcing ribs are substantially perpendicularly butted to form a combined pallet structure.

According to another embodiment of the combined pallet structure disclosed by the present invention, a single panel structure can also be used as the main method. The panel is also a structure that can be linearly produced, and the reinforcing ribs at the bottom are directly strengthened in a generally vertical manner. Ribs, and can further save material costs.

On the other hand, in order to reinforce the strength of the pallet structure, a reinforcement member can be added on the side of the reinforcement rib of the panel or the bottom plate. The reinforcement member can be made of the same or different materials to reinforce the weakness of the structure or increase the strength , And can be applied to various situations.

Specific embodiments for realizing the invention

According to the combined pallet structure disclosed in the present invention, please refer to FIG. 1 first. The combined pallet structure includes a bottom plate 10 and a panel 20. The bottom plate 10 and the panel 20 are slightly flat, and the bottom surface has protruding reinforcing

ribs

11 , 21, and the bottom plate 10 and the panel 20 are both structures that can be linearly produced. In other words, they can be produced by methods such as extrusion, extrusion, and extraction. The cross-sections are roughly the same shape, and the bottom plate 10 and the panel 20 For the same shape, it is only necessary to produce a single mold, which can greatly reduce the manufacturing cost; however, this part is only a preferred embodiment, and does not limit the bottom plate 10 and the panel 20 must be the same shape With appearances. The material can be plastic, paper, foam, polymer, metal, or a combination of more than one material.

Next, referring to FIG. 2, the bottom plate 10 and the panel 20 are combined with the reinforcing

ribs

11 and 21 on one side. The reinforcing

ribs

11 and 21 form an angle. Preferably, the reinforcing

ribs

11 and 21 are in a vertical state. Adhesive, high-frequency bonding, ultrasonic bonding, thermocompression bonding, snapping and other methods are mainly used, depending on the material and the occasion of use; however, the above are only examples and not limited to these methods.

Because it is produced in a linear manner, the reinforcing

ribs

11 and 21 also have a linear arrangement. For example, for the panel 20, the direction parallel to the reinforcing rib 21 is the relatively weak direction of the structure, and the bottom plate 10 is the same. Therefore, it is vertically connected to form a complementary structure, mutually reinforcing the weaknesses of the structure, and providing the strength of the overall pallet structure. If a material such as plastic is used, it can achieve sufficient strength to support the goods being presented, and can be applied to the pallet structure. The gap between the reinforcing

ribs

11 and 21 between the bottom plate 10 and the panel 20 can be inserted into the claw of the stacker to transport the pallet; and because the reinforcing

ribs

11 and 21 of the bottom plate 10 and the panel 20 are roughly perpendicular to each other, The stacker can be inserted in any direction around, which is more convenient to use. Of course, this part is only an embodiment described in conjunction with the drawings, and is not intended to limit the structure that can only be designed to be inserted in any direction.

On the other hand, the reinforcing

ribs

11 and 21 can be roughly sheet-shaped. If the structural strength is considered weak, some or all of the reinforcing

ribs

11 and 21 can be changed to a square hollow structure, which will greatly increase this part. The structural strength of the structure can be arranged at a position where the structural strength is relatively weak, such as a load place, a position where the stacker is inserted, or an edge, etc. At the same time, the square hollow structure is only for illustration, and the shape of any other reinforced structure is Can be applied. Furthermore, in the foregoing embodiments, although referred to as the bottom plate 10 and the panel 20, because the bottom plate 10 and the panel 20 have the same structure, they are not used to limit the direction of their use, that is, both the bottom plate 10 and the panel 20 can be used. For carrying, the other side can be placed on the ground, for example.

On the other hand, please refer to FIG. 3 and FIG. 4, a perforation 12 can also be provided at an appropriate position on the bottom plate 10 for the leg 30 to be set, which is fixed with the nut 31 to fix it. In order to increase the combined strength, the leg 30 may be disposed between the two reinforcing ribs 11, and preferably, in order to further increase the bonding strength, the reinforcing ribs 11 herein may be in a form such as a square hollow with increased strength. After the combination, please refer to FIG. 5, a plurality of legs 30 are added at appropriate positions of the bottom plate 10, and can be placed on the ground to avoid unnecessary abrasion of the surface of the bottom plate 10 and the ground, or are not applicable in part It is used in the environment where the entire plane fits.

Furthermore, in order to further increase the bonding strength, the reinforcing rib 11 of the bottom plate 10 may be provided with a locking groove 111, and the reinforcing rib 21 of the panel 20 is also provided with a corresponding locking groove 211, as shown in FIG. 111 and 211 are fitted with each other to show a knife-and-card type bonding method to greatly increase the bonding strength of the two. After the bonding, they can also be combined with any of the aforementioned methods for bonding, such as adhesive bonding, high frequency bonding, ultrasonic bonding, Hot pressing, etc. Of course, the shapes of the clamping

grooves

111 and 211 are only schematic, and may be any other shapes. At the same time, only the reinforcing ribs 11 of the bottom plate 10 or the reinforcing ribs 21 of the panel 20 may have clamping grooves, which can also be engaged with each other.

On the other hand, please refer to FIG. 7, the bottom surface of the bottom plate 10 and the panel 20 can also be provided with openings to further greatly reduce the material cost, and at the same time can be applied to the situation requiring drainage, for example, the goods are liquid And easy to leak, etc.

Please refer to FIG. 8, which is another embodiment of the combined pallet structure of the present invention. Based on the same concept above, only a single panel 20 can be used as the main body of the pallet. For the structural weakness in the vertical direction, a separate bottom surface is used. The reinforcing ribs 11 are respectively snapped into the locking grooves 211 of the reinforcing ribs 21 of the panel 20, and can also form a combined pallet with a simpler structure. Similarly, the individual reinforcing ribs 11 can also have locking grooves. The individual reinforcing ribs 11 can be obtained by the same molding method as the panel 20, and then the board surface is removed, or the independent reinforcing ribs 11 are separately processed and formed, which is not limited to any manufacturing method.

On the other hand, considering that the pallet structure is suitable for various strength requirements, it may be necessary to open several molds with different structures or materials with different strengths to form, which will increase the manufacturing cost, so please refer to Figure 9 , An additional reinforcing member 40 may be additionally inserted between the reinforcing

ribs

11 and 21 to assist in strengthening the strength of the reinforcing

ribs

11 and 21. The material of the reinforcing member 40 may be the same as or different from the bottom plate 10 or the panel 20, but because of its For reinforcement, a material with a higher specific strength is better, such as aluminum and other metals; however, it is mainly determined by the required strength, and there is no specific limitation on such materials. As far as the drawing is concerned, the space formed by the reinforcing member 40 and the reinforcing

ribs

11 and 21 engaging with each other is preferably a square hollow column, but it is not limited to this type, nor is it necessary to use hollow The way.

Therefore, with the design of the reinforcement 40, a single mold can be used to produce and assemble the pallet, and then according to various use occasions and demand conditions, the reinforcement 40 is used to reinforce the place where it needs to be strengthened, then The manufacturing cost can be saved more without changing the mold according to various usage conditions and needs.

In addition, if considering the transportation cost derived from the volume during transportation, the pallet generally occupies a large volume and is not conducive to long-distance transportation. Therefore, for another embodiment of the combined pallet structure of the present invention, please refer to FIG. 10, Fig. 11, which is composed of a plurality of main body columns 50 and a plurality of

horizontal columns

61, 62. The same main body column 50 and

horizontal columns

61, 62 are also structures that can be linearly produced, in other words, such as extrusion and extrusion , Drawn out, etc., the cross-section is roughly the same shape, by having a plurality of assembly grooves 51 on the main body column 50, with a plurality of

assembly grooves

611, 621 on the

lateral columns

61, 62, can be staggered The configuration is assembled into a combined pallet structure; therefore, before being assembled, it is only a plurality of columnar structures. For the volume during transportation, the pallet will not occupy the extra space as usual, which is not conducive to transportation, in other words The volume occupied during transportation is part of the structure, and there is no waste of extra space between the structures, so it is very suitable for transportation, and can effectively reduce the cost of transportation, overcoming the lack of conventional pallets that cannot be transported for long distances . Furthermore, the closeness of the staggered arrangement of the main body columns 50 and the

lateral columns

61, 62, in other words, the arrangement density of the assembly grooves 51 can be adjusted as needed.

On the other hand, it needs special explanation here. This embodiment is an extension of the embodiment of FIG. 8 of the present invention, which omits the board surface portion of the panel 20 to form the staggered assembly of the reinforcing

ribs

11 and 21. The strength of the sheet-shaped reinforcing

ribs

11 and 21 is slightly insufficient, so it can be thickened to form the current shape of FIG. 10 and FIG. 11, and in order to further save materials and take into account the strength requirements, the main column 50 and The

lateral columns

61 and 62 are designed to be thick and hollow.

In the aspect of FIG. 10 and FIG. 11, the main body column 50 has assembly grooves 51 on the upper and lower sides. Therefore, the

horizontal columns

61 and 62 can be installed on the

assembly grooves

611 and 621 thereon. The upper and lower sides form the

post

61, 62 sandwiching the main post 50, thereby assembling the structure, when the pallet is in use, when the claw of the stacker is inserted, regardless of whether it is inserted in any direction, There are double-sided and staggered structural support without the situation that the structural strength is insufficient to cause the structure to detach or collapse. Furthermore, in order to further increase the strength of the pallet structure, the main column 50 at the hollow portion may have an upper beam 501 and a lower beam 502, and the

beams

61 and 62 have

central ribs

612 and 622, respectively, when assembled, The central rib 612 of the lateral column 61 will contact the upper beam 501 of the main body column 50, and the central rib 622 of the lateral column 62 will contact the lower beam 502 of the main body column 50, so that the overall structure is not only the docking of the assembly groove, but also the cross beam When it is clamped with the central rib to make it stressed (such as carrying goods or being transported by a stacker), the stress of the beam/central rib can be used to distribute the stress, so that the overall structural strength is significantly improved.

The fixing method between the main body column 50 and the

horizontal columns

61 and 62 can be fixed by various methods such as adhesive bonding, high-frequency bonding, ultrasonic bonding, thermocompression bonding, and snap-fitting. The lower two surfaces are joined to each other to clamp and fix the main body column 50 by means of adhesive bonding, high frequency bonding, ultrasonic bonding, thermocompression bonding, and the like. On the other hand, please refer to FIG. 12 and FIG. 13, the

horizontal columns

61 and 62 can also be provided with

buckles

613 and 623 directly to fix each other during production, and can also cooperate with the central stop post 624 to prevent this card Disengagement of the joint relationship; of course, this type of buckle structure is only a schematic illustration with the help of diagrams, and any other fixing method can be applied.

10 and 11 again, the main body column 50 may have a clamping slot 52 at the outermost edge to allow the hook 71 extending inwardly of the edge 70 to be directly hooked in and slide into the sides or sides (horizontal column) 61, 62 can also have the same structure), the same, the edge strip 70 is also preferably a structure that can be linearly produced.

Please refer to Fig. 14 and Fig. 15, in order to increase the convenience of use, this structure can also be combined with the design of the leg post 80. In order to facilitate production and continuity, the leg post 80 also adopts a structure that can be linearly produced, which includes feet The column 81 and the sleeve 82. The leg 81 is the main structure of the leg 80. In order to change to linear production, it is a hollow structure with a plurality of support ribs, which is then installed on the lower half of the sleeve 82 , To improve the support capacity of the leg; the upper support rib can be used as a slot for installation and positioning, directly sleeved at the appropriate position of the main column 50 or the

horizontal columns

61, 62 to form the bottom of the overall pallet Supported leg 80; of course, in addition to the aforementioned nesting method, other assembly methods, such as snapping, hooking, clamping or locking, bonding, etc., are applicable.

Furthermore, please refer to FIG. 16, if the foot post 80 needs to carry the weight of the whole pallet and the cargo on it (static load), it can be matched with the structure shown in FIG. 9 above, and the additional reinforcement member 40 is directly installed into the foot The hollow position in the middle of the pillar 81 assists in strengthening the strength of the foot pillar 81, which can be installed vertically or horizontally to the foot pillar 81. Similarly, the material of the reinforcing member 40 can be the same as the foot pillar 81 Or different, but because it is used for reinforcement, it is better to use a material with a higher specific strength, such as aluminum and other metals; but it is still mainly determined by the required strength, and there is no special restriction on such materials; the same In addition to the hollow cylindrical shape, the reinforcing member 40 can also have any other shape.
