Description

Structure of assembled pallet

Technical Field

The present invention relates to a pallet structure, and more particularly, to a pallet structure formed by combining linear production.

Background

The pallet is a common auxiliary carrying carrier for warehouse logistics and can be used with a stacking machine to carry or stack goods; the most common pallet is a wooden pallet, which is nailed by a plurality of wooden boards to form a structure for carrying objects on one or both sides. However, wooden pallets have several inherent problems, firstly, the cost of the wooden boards is not low, although they can be reused, the impact resistance and moisture resistance are not good, and the weight is heavy, which greatly increases the transportation cost.

In addition to the common wooden pallet, various pallets made of different materials have been developed, such as metal pallet, corrugated paper pallet, plastic pallet, or glued pallet made of composite material, but they are not heavy, have too high manufacturing cost, or have too low recycling rate, and are difficult to completely replace the wooden pallet.

The potential of the plastic pallet is large, and the plastic pallet is low in cost and large in plasticity compared with other materials, is easy to clean, light in weight and moisture-proof; therefore, it is the most important alternative material. However, the plastic pallet has the biggest problem that in order to achieve sufficient strength to form the pallet, the plastic pallet has a complicated structural design to compensate for the rigidity of the material; generally, plastic is mostly formed by injection molding, and the complicated structure design also causes high development cost of the mold, high injection (manufacturing) cost and high time, so that the plastic is difficult to be widely applied and replaces the traditional wooden pallet.

To solve the above problems, a new pallet structure is needed to replace the existing wooden pallet and overcome the related problems.

Disclosure of Invention

Accordingly, the present invention provides a combined pallet structure, which can solve the above-mentioned drawbacks of the prior art, and can be manufactured by using a linear manufacturing process, so as to greatly reduce the manufacturing and production costs.

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

The combined pallet structure according to the present invention comprises a base plate and a face plate, both of which are linearly producible and can be manufactured in a simple and inexpensive manner such as extrusion, extraction, etc., wherein the base plate and the face plate have a plurality of reinforcing ribs and are joined in a manner such that the reinforcing ribs are substantially vertically butted to each other to form the combined pallet structure.

According to another embodiment of the present invention, a single panel structure can be used as a main body, the panel is also a linearly producible structure, and the reinforcing ribs are directly joined to the reinforcing ribs in a substantially vertical manner, thereby further saving material costs.

On the other hand, in order to reinforce the strength of the pallet structure, a reinforcing member can be added on the side of the reinforcing rib of the panel or the base plate, and the reinforcing member can be made of the same or different materials, so as to reinforce the weak point of the structure or increase the strength, and be suitable for various conditions.

According to another embodiment of the present invention, the combined pallet structure comprises a plurality of main columns and a plurality of cross columns, wherein the main columns and the cross columns are linearly producible structures, and have assembling slots thereon, and can be assembled in a staggered manner to form the combined pallet structure, so as to greatly save the occupied volume during transportation, and further greatly reduce the transportation cost.

Detailed Description

Referring to fig. 1, the combined pallet structure according to the present invention includes a base plate 10 and a face plate 20, wherein the base plate 10 and the face plate 20 are slightly flat, the bottom surfaces of the base plate 10 and the face plate 20 have protruding reinforcing

ribs

11, 21, and the base plate 10 and the face plate 20 are both linearly producible structures, in other words, the combined pallet structure can be produced by methods such as extrusion, extraction, and the like, the cross sections of the base plate and the face plate are substantially the same shape, and the base plate 10 and the face plate 20 are preferably the same shape, and only a single mold is required for production, thereby reducing the manufacturing cost more; however, this section is only a preferred embodiment, and it is not limited that the bottom plate 10 and the face plate 20 are necessarily the same shape and shape. The material may be plastic, paper, foam, polymer, metal, or a combination of more than one material.

Referring to fig. 2, the bottom plate 10 and the face plate 20 are assembled by abutting the reinforcing

ribs

11, 21, wherein the reinforcing

ribs

11, 21 form an included angle, preferably a substantially vertical state, and the bonding method can be adhesive bonding, high frequency bonding, ultrasonic bonding, thermal bonding, clamping, etc., depending on the material and the application; however, the above are only examples and are not limited to these methods.

Because the

reinforcing ribs

11, 21 are produced in a linear manner, the

reinforcing ribs

11, 21 are also arranged in a linear manner, for example, the direction parallel to the reinforcing ribs 21 is the direction with a relatively weak structure for the panel 20, and the same principle is applied to the base plate 10, so that the reinforcing ribs are vertically butted together to form a complementary structure, and the weak points of the structures are mutually reinforced, thereby providing the strength of the whole pallet structure. If the pallet is made of plastic, the strength of the pallet can be sufficient to support goods, and the pallet can be suitable for the pallet structure. The gap between the

reinforcing ribs

11 and 21 between the base plate 10 and the face plate 20 can be inserted by the claw of the stacking machine to carry the pallet; and because the reinforcing

ribs

11, 21 of the bottom plate 10 and the face plate 20 are approximately perpendicular to each other, the fork lift can be inserted in any direction around, and the use is more convenient. Of course, this portion is only the embodiment described with reference to the drawings, and is not intended to limit the structure that can be inserted in any direction.

On the other hand, the

reinforcing ribs

11, 21 may be substantially sheet-shaped, and if the structural strength is weak, some or all of the reinforcing

ribs

11, 21 may be modified to be square hollow structure, which can greatly increase the structural strength of the part, and the part may be disposed at a position where the structural strength is weak, such as a load-bearing position, a stacker insertion position, or an edge; meanwhile, the square hollow structure is only schematic, and the shape of any other reinforcing structure can be suitable. Furthermore, although the base plate 10 and the face plate 20 are referred to in the foregoing embodiments, the base plate 10 and the face plate 20 are not limited to the same structure, i.e. both the base plate 10 and the face plate 20 can be used for carrying and the other can be used on the ground.

On the other hand, referring to fig. 3 and 4, a through hole 12 may be formed at a suitable position of the bottom plate 10 for the leg 30 to be disposed, which is fixed by a nut 31, and in order to increase the strength after the bonding, the leg 30 may be disposed between two reinforcing ribs 11, and preferably, in order to further increase the bonding strength, the reinforcing ribs 11 may be in a form of increasing the strength, such as a square hollow shape. After combination, referring to fig. 5, a plurality of pillars 30 are additionally disposed at appropriate positions of the bottom plate 10 for being placed on the ground, thereby preventing unnecessary wear of the surface of the bottom plate 10 and the ground or use in an environment partially unsuitable for the entire plane.

Furthermore, in order to further increase the bonding strength, the reinforcing ribs 11 of the bottom plate 10 may be provided with the notches 111, and the reinforcing ribs 21 of the face plate 20 may also be provided with the corresponding notches 211, as shown in fig. 6, the

notches

111 and 211 are engaged with each other to form a knife-clip type bonding method, so as to greatly increase the bonding strength between the two, and after bonding, any one of the above methods, such as adhesive bonding, high frequency bonding, ultrasonic bonding, and thermal bonding, may be further used. Of course, the shapes of the

locking grooves

111 and 211 are merely schematic, and may be any other shapes, and only the reinforcing rib 11 of the chassis 10 or the reinforcing rib 21 of the face plate 20 may have a locking groove, and they may be engaged with each other in the same manner.

On the other hand, referring to fig. 7, the bottom plate 10 and the panel 20 may be formed with openings to further reduce the material cost, and is suitable for the situation requiring drainage, such as the case where the goods are liquid and easy to leak.

Referring to fig. 8, in another embodiment of the combined pallet structure of the present invention, based on the same concept, only a single deck 20 may be used as the pallet body, and the weak structural strength in the vertical direction may be achieved by using the reinforcing ribs 11 individually installed on the bottom surface to be respectively inserted into the slots 211 of the reinforcing ribs 21 of the deck 20, so as to form a combined pallet with a simpler structure, and similarly, the reinforcing ribs 11 individually installed may also have slots. The individual reinforcing ribs 11 may be obtained by forming the panel 20 in the same manner and then removing the panel surface, or the individual reinforcing ribs 11 may be formed by machining individually, which is not limited to any manufacturing method.

On the other hand, considering that if the pallet structure is to be suitable for various strength requirements, it may need to open several molds with different structures or materials with different strengths for molding, which will increase the manufacturing cost, therefore, please refer to fig. 9, a reinforcement member 40 may be additionally 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 may be the same as or different from that of the bottom plate 10 or the face plate 20, but because it is for reinforcement, it is better to use a material with higher specific strength, such as a metal like aluminum; however, the material is not particularly limited, and is mainly defined by the required strength. In the drawings, the reinforcing member 40 is preferably a square hollow column shape in cooperation with a space formed by the mutual engagement of the reinforcing

ribs

11, 21, but the form is not limited thereto, and the hollow form is not necessarily adopted.

Therefore, by means of the design of the reinforcing member 40, the pallet can be produced and assembled by a single mold, and then the reinforcing member 40 is used for reinforcing the position needing to be reinforced according to various use occasions and requirements, so that the manufacturing cost can be saved, and the mold does not need to be changed according to various use conditions and requirements.

Furthermore, if considering the transportation cost derived from the volume during transportation, the pallet generally occupies a large volume and is not favorable for long-distance transportation, so another embodiment of the combined pallet structure of the present invention, please refer to fig. 10 and 11, which is composed of a plurality of main columns 50 and a plurality of

cross columns

61 and 62, the same main columns 50 and cross

columns

61 and 62 are also structures that can be produced linearly, in other words, can be produced by methods such as extrusion, extraction, etc., and have a cross section that is roughly the same shape, by having a plurality of assembly slots 51 on the main columns 50, and a plurality of

assembly slots

611 and 621 on the

cross columns

61 and 62, they can be assembled into a combined pallet structure in a staggered arrangement; therefore, the pallet is only provided with a plurality of columnar structures before being assembled, and the volume in transportation is not unfavorable for transportation as the conventional pallet occupies extra space. Furthermore, the tightness of the staggered arrangement of the main body posts 50 and the lateral posts 61, 62, i.e. the arrangement density of the assembling slots 51, can be adjusted as required.

On the other hand, it should be specifically explained here that this embodiment is an extension of the embodiment of fig. 8 of the present invention, and the plate surface portion of the panel 20 is omitted again to form a state of staggered assembly of the reinforcing

ribs

11, 21, but the strength of the sheet-shaped reinforcing

ribs

11, 21 is slightly insufficient, so that it can be thickened to form the state of fig. 10, 11, and the main body column 50 and the

cross columns

61, 62 are designed to be thickened and hollow in order to further save material and meet the strength requirement.

In the aspect of fig. 10 and 11, the main body column 50 has the assembling grooves 51 at both the upper and lower sides, so the

horizontal columns

61 and 62 can be assembled at both the upper and lower sides by the assembling

grooves

611 and 621 thereon to form the aspect that the

horizontal columns

61 and 62 sandwich the main body column 50, and by this assembling structure, when the pallet is used, the claw part of the forklift is inserted, no matter the pallet is inserted in any direction, the pallet can be supported by the double-sided and staggered structure, and the situation that the structure is separated or collapsed due to insufficient structural strength can not occur. Furthermore, in order to further increase the strength of the pallet structure, the main column 50 may have an upper beam 501 and a lower beam 502 in the hollow portion thereof, and the

columns

61, 62 may have

central ribs

612, 622 respectively, when assembled, the central rib 612 of the column 61 may contact the upper beam 501 of the main column 50, and the central rib 622 of the column 62 may contact the lower beam 502 of the main column 50, so that the overall structure is not only the butt joint of the assembly slots, but also when stressed (such as carrying goods or transporting by a stacker) by the fastening of the beams and the central ribs, the stress may be dispersed by the joint structure of the beams/the central ribs, so that the overall structure strength is significantly improved.

The main body column 50 and the

lateral columns

61 and 62 may be fixed by various means such as adhesion, high frequency bonding, ultrasonic bonding, thermocompression bonding, or engagement, or the main body column 50 may be held and fixed by adhesion, high frequency bonding, ultrasonic bonding, thermocompression bonding, or the like by bonding the upper and lower surfaces of the

lateral columns

61 and 62 to each other. On the other hand, referring to fig. 12 and 13, during production, the

transverse posts

61 and 62 may be directly provided with the

fasteners

613 and 623 for fastening and fixing, and the central stop post 624 may be matched to prevent the disengagement of the fastening relationship; of course, the fastening structure is only illustrated with reference to the drawings, and any other fastening method can be applied.

Referring back to fig. 10 and 11, the main body column 50 may have a slot 52 at the edge thereof for allowing a hook 71 extending inward from the edge of the edge strip 70 to be hooked directly and slidably fitted to both sides or the periphery (the

cross columns

61, 62 may have the same structure), and in the same way, the edge strip 70 may have a linearly producible structure.

Referring to fig. 14 and 15, in order to increase the convenience of use, the structure may also be combined with the design of the leg post 80, in order to facilitate and consistency the production, the leg post 80 also adopts a linearly producible structure, which includes a leg post body 81 and a sleeve 82, the leg post body 81 is a main structure of the leg post 80, and in order to change to the linear production, it is a hollow structure with a plurality of supporting ribs, and the sleeve 82 is mounted on the lower half portion thereof to enhance the supporting capability of the leg post; the upper supporting ribs can be used as mounting and positioning slots to be directly sleeved at the proper positions of the main body columns 50 or the

transverse columns

61 and 62 to form the socle 80 for supporting the bottom of the whole pallet; of course, other assembling methods, such as engaging, hooking, clamping, locking, and adhering, may be used besides the sleeving method.

Further, referring to fig. 16, if the weight (static load) of the entire pallet and the goods thereon is considered, the structure of fig. 9 can be combined with the additional reinforcing member 40 directly installed in the hollow position in the middle of the leg column 81 to assist in enhancing the strength of the leg column 81, which can be installed vertically or horizontally with respect to the leg column 81, and similarly, the material of the reinforcing member 40 can be the same as or different from that of the leg column 81, but because it is for reinforcing, it is preferable to use a material with higher specific strength, such as a metal like aluminum; however, the strength is still limited by the required strength, and the material is not particularly limited; similarly, the reinforcing member 40 may have any shape other than the hollow cylindrical shape.

Although the present invention has been described with reference to the above preferred embodiments, it should be understood that the invention is not limited to the embodiments, and the connection of the components of the invention is not limited to the embodiments, but rather may be modified and modified without departing from the spirit and scope of the invention.
