Description

Combined pallet structure

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

Pallets are a common auxiliary carrier for warehousing and logistics. They can be used with stackers to move or stack goods; the most common pallets are wooden pallets, which are nailed by several wooden boards to form a single-sided or The structure of the double-sided presentation. However, wooden pallets have several inherent problems. First of all, the cost of wooden pallets is not low. Although they can be reused, they have poor impact resistance and moisture resistance. At the same time, they are also heavy, which greatly increases the cost of transportation.

In addition to the common wooden pallets, various pallets of different materials have also been developed, such as metal pallets, corrugated paper pallets, plastic pallets, or laminated pallets made of composite materials, but they are not too heavy and costly to manufacture. Too high, otherwise the reuse rate is too low, and it is currently difficult to completely replace the wooden pallets.

Among them, plastic pallets have greater potential, because the cost of plastic materials is relatively low compared to other materials, and they are plastic, easy to clean, lighter, and moisture-proof; therefore, they are the most important substitute materials. However, the biggest problem with plastic pallets is that in order to achieve sufficient strength to form pallets, the more complex structural design of plastic pallets compensates for the rigidity of the material itself; and general plastics mostly use injection molding, which is complicated The structural design of the company also makes the mold development cost high, and the injection (manufacturing) cost and time are also high, so it is difficult It is widely used and replaces traditional wooden pallets.

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

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

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

According to the combined pallet structure disclosed in the present invention, it includes a bottom plate and a panel. Both the bottom plate and the panel are structures that can be linearly produced and can be manufactured by simple and inexpensive methods such as extrusion, extrusion, and extraction. It has a plurality of reinforcing ribs with the panel, and they are joined in such a way that the reinforcing ribs are almost perpendicular to each other to form a combined pallet structure.

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

On the other hand, in order to reinforce the strength of the pallet structure, reinforcements can be added to the side of the reinforcement ribs of the panel or bottom plate. The reinforcements can be made of the same or different materials to reinforce structural weaknesses or increase the strength. In various situations.

According to another embodiment of the combined pallet structure disclosed in the present invention, it includes a plurality of main columns and a plurality of horizontal columns. Both the main column and the horizontal column are linearly-producible structures with assembling grooves on them. It can be assembled in staggered configuration to form a combined pallet structure, which can greatly Width saves the volume occupied during transportation, thereby greatly reducing transportation costs.

According to the combined pallet structure disclosed in the present invention, please firstly refer to Figure 1. The combined pallet structure includes a bottom plate 10 and a face plate 20. The bottom plate 10 and the face plate 20 cover are slightly flat, and the bottom surface has protruding reinforcing ribs. 11, 21, and the bottom plate 10 and the panel 20 are both linearly produced structures. In other words, they can be produced by methods such as extrusion, extrusion, and extraction. Slightly the same shape, and at the same time, the bottom plate 10 and the face plate 20 are preferably the same shape, only a single mold is required for production, which can greatly reduce the manufacturing cost; however, this part is only a preferred embodiment and is not a limitation The bottom plate 10 and the panel 20 must have the same shape and form. The material can be plastic, paper, foam, polymer, metal, or a combination of more than one material, etc.

Next, please refer to Figure 2. The bottom plate 10 and the panel 20 are combined with reinforcing ribs 11, 21 on one side, and the reinforcing ribs 11, 21 will form an included angle. Preferably, it is roughly vertical, and the joining method can be Adhesive, high-frequency bonding, ultrasonic bonding, thermal compression, clamping and other methods are used, which mainly depend on the material and the occasion of use; but the above are only examples and are not limited to only these methods.

Because it is produced in a linear manner, the reinforcing ribs 11 and 21 also have a linear arrangement. For example, in the case of the panel 20, the direction parallel to the reinforcing rib 21 is the relatively weaker structure, and the bottom plate 10 is also the same. Therefore, it adopts a vertical docking method to form complementary structures, which mutually reinforce the weaknesses of the structure, and can provide the strength of the overall pallet structure. If it is made of materials such as plastic, it can also achieve sufficient strength to support the presented goods, and it 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 by the claws of the stacker to carry the pallets; 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 it, 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, 21 can be roughly sheet-shaped. If considering its weak structural strength, part or all of the reinforcing ribs 11, 21 can be changed to a square hollow structure, which will greatly increase this part. The structural strength, which can be placed in a position with relatively weak structural strength, such as Heavy points, stacker insertion positions, or edges, etc.; at the same time, the square hollow structure is only for illustration, and any other reinforced structure shape can be applied. Furthermore, in the foregoing embodiments, although the bottom plate 10 and the panel 20 are referred to as the bottom plate 10 and the panel 20, since the bottom plate 10 and the panel 20 have the same structure, they are not used to limit the direction of use, that is, both sides of 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, referring to Figures 3 and 4, a perforation 12 can also be provided at an appropriate position of the bottom plate 10 for the foot post 30 to be installed, which is fixed by the nut 31. In order to increase the strength of the joint, the foot post 30 can be arranged between two reinforcing ribs 11, and preferably, in order to further increase the bonding strength, the reinforcing ribs 11 here can be, for example, a square hollow shape with increased strength. After assembling, please refer to Figure 5. A plurality of foot posts 30 are added to the appropriate positions of the bottom plate 10, which can be placed on the ground to avoid unnecessary abrasion of the surface of the bottom plate 10 and the ground, or parts of the legs are not It is suitable for use in the environment where the entire plane is attached.

Furthermore, in order to further increase the bonding strength, the reinforcing rib 11 of the bottom plate 10 can be provided with a card slot 111, and the reinforcing rib 21 of the panel 20 can also be provided with a corresponding card slot 211, as shown in Figure 6, by the card The grooves 111 and 211 are fitted with each other to present a knife-clip type combination to greatly increase the bonding strength of the two. After the combination, it can also be combined with any of the foregoing methods, such as glue, high-frequency bonding, ultrasonic bonding, Hot pressing, etc. Of course, the shape of the grooves 111 and 211 is only for illustration, and can be any other shape. At the same time, only the reinforcing rib 11 of the bottom plate 10 or the reinforcing rib 21 of the panel 20 may have grooves, and they can also be mutually engaged.

On the other hand, please refer to Figure 7. The bottom plate 10 and the panel 20 can also be provided with openings to further reduce the material cost. At the same time, it is more suitable for conditions that require drainage. For example, the displayed goods are Liquid and easy to leak, etc.

Please refer to Figure 8, which is another embodiment of the combined pallet structure of the present invention. Based on the same concept as described above, only a single panel 20 can be used as the main body of the pallet. For structural strength weaknesses in the vertical direction, use the bottom surface alone. The reinforcing ribs 11 are respectively clamped into the grooves 211 of the reinforcing ribs 21 of the panel 20 to form a combined pallet with a simpler structure. Similarly, a single reinforcing rib 11 may also have a groove. The individual reinforcement rib 11 can be obtained by the same molding method as the panel 20, and then the panel surface is removed, or the individual reinforcement rib 11 can be formed separately, which is not limited to any manufacturing method.

On the other hand, considering that if 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 for molding, which will increase the manufacturing cost. Therefore, please refer to Figure 9. , An additional reinforcement member 40 can be inserted between the reinforcement ribs 11, 21 to assist in enhancing the strength of the reinforcement ribs 11, 21. The material of the reinforcement member 40 can be the same as or different from the bottom plate 10 or the panel 20, but because it is a reinforcement It is better to use a material with a higher specific strength, such as aluminum and other metals; but it is mainly defined by the required strength, and there is no special restriction on this type of material. As far as the diagram is concerned, the reinforcing member 40 cooperates with the reinforcing ribs 11 and 21 to form a space formed by mutual engagement, preferably a square hollow cylindrical shape, but it is not limited to this type, and there is no limitation that it must be hollow. The way.

Therefore, with the design of the reinforcing piece 40, a single mold can be used to produce and assemble the pallet, and then according to various use occasions and demand conditions, the reinforcing piece 40 can be used to reinforce the place where reinforcement is needed, which can save manufacturing. No need to change the mold according to various usage conditions and needs.

Moreover, if the transportation cost derived from the volume during transportation is considered, the pallet generally occupies a large volume and is not conducive to long-distance transportation. Therefore, the combined pallet structure of the present invention For another embodiment, please refer to Figures 10 and 11, which are composed of a plurality of main columns 50 and a plurality of horizontal columns 61 and 62. The same main column 50 and horizontal columns 61 and 62 are also linearly produced. In other words, it can be produced by methods such as extrusion, extrusion, and extraction. Its cross-sections are roughly the same shape. The main column 50 has a plurality of assembling slots 51, and the horizontal columns 61 and 62 have a plurality of assembling slots. Slots 611 and 621 can be arranged in a staggered arrangement and assembled into a combined pallet structure; therefore, it is only a plurality of columnar structures before being assembled, and the volume during transportation will not be occupied as conventional pallets. The extra space 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 structures. Therefore, it is very suitable for transportation and can effectively reduce the cost of transportation. , To overcome the lack of long-distance transportation of conventional pallets. Furthermore, the tightness of the staggered arrangement of the main body column 50 and the horizontal columns 61 and 62, in other words, the arrangement density of the assembly groove 51 can be adjusted as required.

On the other hand, it needs special explanation here. This embodiment is an extension of the embodiment in Figure 8 of the present invention. The surface part of the panel 20 is omitted to form a staggered assembly of the reinforcing ribs 11 and 21. However, the strength of the flaky reinforcing ribs 11, 21 is slightly insufficient, so it can be thickened to form the current state of Figures 10 and 11. In order to further save materials and take into account the strength requirements, the main column 50 and horizontal pillars 61, 62 are designed to be thick and hollow.

As for the aspect of Figures 10 and 11, the main body post 50 has assembly grooves 51 on both the upper and lower sides. Therefore, the horizontal posts 61 and 62 can be installed in the assembly grooves 611 and 621 on them. The upper and lower sides form a state in which the horizontal columns 61 and 62 sandwich the main column 50. With this assembly structure, when the pallet is used, when the claw of the stacker is inserted, it will be inserted in any direction. There are double-sided and staggered structural support, and the structure will not break away or collapse due to insufficient structural strength. Furthermore, in order to further increase the strength of the pallet structure, the main column 50 in the hollow part may have an upper horizontal The beam 501 and the lower beam 502, and the beams 61 and 62 have central ribs 612, 622, respectively. When assembled, the central rib 612 of the beam 61 will contact the upper beam 501 and the central ribs of the beam 62 of the main column 50 622 will contact the lower cross beam 502 of the main column 50, so that the overall structure is not only the butt joint of the assembly slot, but also when the cross beam and the central rib are clamped to be stressed (such as carrying goods or handling by a stacker), The stress can be dispersed by the bonding structure of the beam/central rib, so that the overall structure 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 glue, high frequency bonding, ultrasonic bonding, thermocompression bonding, and clamping, or using the horizontal columns 61 and 62 above and below. The two sides are joined to each other to clamp and fix the main body column 50 by means of gluing, high-frequency joining, ultrasonic joining, thermocompression and the like. On the other hand, please refer to Figures 12 and 13, during production, the horizontal posts 61 and 62 can directly have buckles 613 and 623 to lock each other, and the central stop post 624 can be used to prevent this Of course, this kind of buckle structure is only shown in conjunction with the diagram, and any other fixing methods are applicable.

Returning to Figures 10 and 11, the outermost edge of the main column 50 can have a slot 52, which can be directly hooked in by the hook 71 extending inward from the edge of the side strip 70, and is installed on both sides or around (the horizontal column) in a sliding manner. 61 and 62 can also have the same structure). Similarly, the edge strip 70 can also have a structure that can be linearly produced.

Please refer to Figures 14 and 15 for the continuation. In order to increase the convenience of use, this structure can also be combined with the design of the foot post 80. In order to make production convenient and consistent, the foot post 80 also adopts a linear production structure, which includes feet The column body 81 and the sleeve 82. The foot column body 81 is the main structure of the foot column 80. In order to change to linear production, it is a hollow structure with a plurality of supporting ribs. The sleeve 82 is installed on the lower half of it. , To enhance the supporting capacity of the foot post; and the upper support rib can be used as a slot for installation and positioning, to be directly sleeved on the main body post 50 or the horizontal post 61, 62 at the appropriate position to form The foot post 80 supported at the bottom of the overall pallet; of course, in addition to the aforementioned nesting method, other assembly methods such as snapping, hooking, clamping, or locking, bonding, etc., are all applicable.

Furthermore, please refer to Figure 16. If considering that the foot post 80 needs to carry the weight of the overall pallet and the cargo on it (static load), it can be directly installed in conjunction with the structure of the aforementioned Figure 9 with the additional reinforcement 40 The hollow position in the middle of the foot post 81 helps to enhance the strength of the foot post 81, which can be installed vertically or horizontally to the foot post 81. Similarly, the material of the reinforcing member 40 can be the same as that of the foot post 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 mainly determined by the required strength, and there is no special restriction on this type of material; the same, The reinforcing member 40 may have any other shape besides the hollow cylindrical shape.

Although the present invention is disclosed in the foregoing preferred embodiment as above, it is not intended to limit the present invention, and the connection type of the components of the present invention is not limited to the embodiment without departing from the same spirit of the invention, as long as it does not deviate from Within the spirit and scope of the present invention, some changes and modifications can be made. Therefore, the scope of protection of the present invention shall be subject to the scope of the attached patent application.
