Abstract
Description
Variable size assembly pallet
[0001] The present invention relates to a size-variable assembly pallet, and more particularly, to a size-variable assembly pallet capable of providing compatibility for pallets of two different specifications by adjusting the position of side members slidably assembled on both sides of a main body.
[0002] In general, a pallet is formed in the shape of a plate with flat upper and lower surfaces, and a space is formed between the upper and lower surfaces into which a forklift, such as a forklift, can be inserted. After a certain amount of goods are loaded on the upper surface of the pallet, a forklift can be used to transport a large quantity of goods at once, and it is a product used to efficiently manage logistics operations.
[0003] These pallets are a fundamental element of logistics modularization for unit loading, unloading, and transporting cargo. They are manufactured to a certain standard to enable efficient loading of cargo according to the specifications of cargo trucks, freight train cargo cars, and containers. In Korea, the KS standard specifications T11 type (1,100mm x 1,100mm) and T12 type (1,200mm x 1,000mm) are mainly used. In the United States, 1,219 x 1,016mm are used, and in Europe, 1,200 x 800mm are used.
[0004] Thus, pallet specifications vary depending on country or intended use. Logistics systems for transport and handling operate based on pre-established specifications, making pallets with different specifications difficult to use. Consequently, when pallet specifications differ between the exporting and importing countries, it becomes difficult for the importing country to reuse the exporting country's pallets. This necessitates the process of collating and returning the pallets to the exporting country, increasing logistics costs.
[0005] Furthermore, manufacturing pallets of various specifications requires separate molds for each specification, which incurs additional mold manufacturing costs. This not only increases the cost of pallet manufacturing, but also ultimately increases logistics costs, as pallets of various specifications must be manufactured, distributed, and stored.
[0006] Recently, due to issues such as environmental problems and resource recycling, pallets are being manufactured in an assembly manner using high-strength, lightweight metals such as aluminum alloys. However, these metal pallets also have the problem of having to manufacture parts according to each specification.
[0007] In addition, since the loading area varies depending on the size of the cargo, only standard size pallets cannot be used. Therefore, industrial sites directly manufacture and use pallets of various sizes corresponding to the loading area of the cargo. However, these pallets have the problem that they are difficult to manufacture in advance, require a lot of manufacturing time, and require a lot of manufacturing labor costs.
[0008] Therefore, there is a need to develop a palette that can be changed into various specifications by varying the size depending on the usage environment.
[0009] Accordingly, the purpose of the present invention is to solve the above-described conventional problems, and to provide a size-variable assembly pallet that can provide compatibility for two different standard pallets by adjusting the position of side members slidably assembled on both sides of the main body.
[0010] In addition, the present invention provides a size-variable assembly pallet that can prevent the connection between the main body and the side members from being damaged or deformed due to the weight of the load by increasing the bonding strength of the side members to the main body.
[0011] The above object is achieved by a size-variable pallet according to the present invention, comprising: a main body; a side member slidably assembled on at least one side of the main body in a direction approaching or away from the main body; and a fastening member for fixing a moving position of the side member, wherein the side member can move to a first position approaching the main body to provide a pallet of a first specification, or to a second position away from the pallet body to provide a pallet of a second specification different from the first specification.
[0012] Here, it is preferable that a plurality of sliding grooves and sliding bars are formed on the facing surfaces of the main body and the side member to engage with each other in the sliding direction to guide sliding of the side member.
[0013] Additionally, it is preferable that a reinforcing rib be formed protruding along the length of the sliding bar on one side of the sliding bar.
[0014] In addition, it is preferable that a joining groove be formed on one side of the sliding groove into which the reinforcing rib can be slidably inserted.
[0015] In addition, it is preferable that the reinforcing rib has a T-shaped cross-sectional shape.
[0016] In addition, it is preferable that the above-mentioned joining groove has a cross-sectional shape corresponding to the reinforcing rib so that it can be engaged with the reinforcing rib.
[0017] Additionally, it is preferable that the reinforcing rib be placed on the upper or lower side of the sliding bar.
[0018] Additionally, it is preferable that the fastening member include a fastening screw capable of restraining or releasing the sliding of the side member relative to the pallet body.
[0019] In addition, the fastening part includes a first fixing bar arranged on the main body and a second fixing bar arranged on the side member and slidably coupled to the first fixing bar, and it is preferable that the first fixing bar and the second fixing bar each have a fastening hole that communicates with each other so that a fastening screw can be fastened while the side member is moved to the first position or the second position.
[0020] According to the present invention, a size-variable assembly pallet is provided that can provide compatibility for pallets of two different specifications by adjusting the positions of side members slidably assembled on both sides of a main body.
[0021] In addition, a size-variable assembly pallet is provided that can prevent the connection between the main body and the side members from being damaged or deformed due to the weight of the load by increasing the bonding strength of the side members to the main body.

[0028] Before the explanation, in several embodiments, components having the same configuration will be described representatively in the first embodiment using the same symbols, and in other embodiments, configurations different from the first embodiment will be described.
[0029] Hereinafter, a size-variable assembly pallet according to a first embodiment of the present invention will be described in detail with reference to the attached drawings.
[0030] Among the attached drawings, FIGS. 1 and 2 are perspective views of the size-variable assembly pallet of the present invention, and FIGS. 3 and 4 are exploded perspective views of the size-variable assembly pallet of the present invention.
[0031] FIG. 1 shows a state in which a side member (120) has moved to a first position closer to the main body (110) to provide a pallet of a first specification, and FIG. 2 shows a state in which a side member (120) has moved to a second position away from the main body (110) to provide a pallet of a second specification different from the first specification.
[0032] The size-variable assembly pallet of the present embodiment can provide a pallet of a first specification or a second specification by sliding the side members (120) arranged on both sides of the main body (110) in a direction approaching or away from the main body (110). In the present embodiment, the first specification is set to the European EUR pallet specification of 1,200 * 800 mm, and the second specification is set to the KS standard T12 pallet specification of 1,200 * 1,000 mm, but is not limited thereto.
[0033] The size-variable assembly pallet of the present invention as shown in the above drawing includes a main body (110), a side member (120), and a fastening part (130).
[0034] The above main body (110) includes a rectangular first upper plate member (111) and a first foot member (112) protruding from the lower surface of the first upper plate member (111).
[0035] On both sides of the first upper plate member (111), a plurality of sliding grooves (113) are arranged in parallel to guide the sliding of the side member (120), and a T-shaped cross-section joining groove (114) is formed on the upper or lower side of the sliding groove.
[0036] Additionally, a first fixing groove (115) to which a first fixing bar (132) can be coupled is formed at the center and both ends of both sides of the first upper plate member (111).
[0037] The side member (120) includes a rectangular second upper member (121) and a second foot member (122) protruding from the lower surface of the second upper member (121), and is slidably assembled on both sides of the main body (110), and can move to a first position close to the main body (110) to provide a pallet of a first specification, or move to a second position away from the pallet body to provide a pallet of a second specification different from the first specification.
[0038] The first upper plate member (111) of the main body (110) may be formed to be approximately 1,200 * 400 mm, and the second upper plate member (121) of the side member (120) may be formed to be approximately 1,200 * 200 mm. The gap between the first position and the second position of the side members (120) assembled on each side of the main body (110) may be set to approximately 100 mm. Accordingly, when the side member (120) is moved to the first position, a pallet of the first specification of 1,200 * 800 mm may be provided, and when the side member (120) is moved to the second position, a pallet of the second specification of 1,200 * 1,000 mm may be provided.
[0039] On one side of the second upper plate member (121), a plurality of sliding bars (123) that can be inserted into the sliding groove (113) are arranged in parallel, and a reinforcing rib (124) having a T-shaped cross-section is formed on the upper or lower side of the sliding bar (123).
[0040] The above reinforcing ribs (124) can be formed alternately on the upper and lower sides along the arrangement direction of the reinforcing ribs (124), and the upper surface of the reinforcing ribs (124) located on the upper side is set to be located on the same plane as the upper surface of the first upper plate member (111).
[0041] That is, in a state where the side member (120) is moved to a second position spaced apart from the main body (110) to provide a pallet of the second specification, the first upper plate member (111) and the second upper plate member (121) are maintained in a state of being connected by the sliding bar (123). At this time, since the upper surface of the reinforcing rib (124) forms the same plane as the upper surfaces of the first upper plate member (111) and the second upper plate member (121), it is possible to prevent snagging due to a step in the process of loading or unloading a load on the upper surface of the pallet.
[0042] Additionally, a second fixing groove (125) to which a second fixing bar (133) can be coupled is formed in the center and both ends of one side of the second upper plate member (121).
[0043] The above-mentioned fastening part (130) includes a first fastening bar (132) fixed to a first fastening groove (115) of the main body (110), a second fastening bar (133) fixed to a second fastening groove (125) of the side member (120) and slidably coupled with the first fastening bar (132), and a fastening screw (131) capable of constraining a coupling position of the second fastening bar (133) to the first fastening bar (132) when the second fastening bar (133) is moved to a first position or a second position together with the side member (120).
[0044] The first fixed bar (132) may be formed of a square pipe having a hollow portion formed therein, and the second fixed bar (133) may be formed of a length member that can be inserted into the hollow portion of the first fixed bar (132).
[0045] The first fixing bar (132) and the second fixing bar (133) may be made of a durable metal material, and the main body (110) and the side member (120) may be made of a synthetic resin material. Accordingly, the main body (110) and the side member (120) can be easily manufactured, while the fastening portion (130) can be prevented from being easily worn or damaged during repeated standard deformation processes.
[0046] A reference fastening hole (132a) is formed in the first fixing bar (132), and a first fastening hole (133a) communicating with the reference fastening hole (132a) at a first position and a second fastening hole (133b) communicating with the reference fastening hole (132a) at a second position are formed in the second fixing bar (133). Therefore, when the side member (120) is moved to the first position, a fastening screw (131) is fastened to the reference fastening hole (132a) and the first fastening hole (133a) which are in communication with each other, thereby fixing the position of the side member (120), or when the side member (120) is moved to the second position, a fastening screw (131) is fastened to the reference fastening hole (132a) and the second fastening hole (133b) which are in communication with each other, thereby fixing the position of the side member (120).
[0047] Meanwhile, the first fixing bar (132) can be fixed by a fastening element such as a rivet that does not allow arbitrary separation while being inserted into the first fixing groove (115) of the main body (110), and the second fixing bar (133) can also be fixed by a fastening element such as a rivet while being inserted into the second fixing groove (125) of the side member (120).
[0048]
[0049] From now on, the operation of the first embodiment of the above-described size-variable assembly pallet will be described.
[0050] Among the attached drawings, Fig. 5 is a plan view of a size-variable assembly pallet of the present invention, Fig. 6 is a cross-sectional view taken along line A-A' of Fig. 5, and Fig. 7 is a cross-sectional view taken along line B-B' of Fig. 5.
[0051] As illustrated in FIGS. 5 to 7, the side members (120) slidably connected to each of the two sides of the main body (110) can provide a pallet of the first specification in a state where they are moved to a first position close to the main body (110).
[0052] Looking at the coupling structure that guides the sliding of the side member (120) and the main body (110), as illustrated in FIG. 6, a plurality of sliding bars (123) arranged in a parallel shape on one side of the second upper plate member (121) of the side member (120) are each coupled in a sliding state to a plurality of sliding grooves (113) arranged in a parallel shape on the side of the first upper plate member (111) of the main body (110), and in this state, as the sliding bars (123) slide in the longitudinal direction within the sliding grooves (113), the sliding of the side member (120) can be guided.
[0053] In particular, the reinforcing rib (124) formed on the upper or lower side of the sliding bar (123) is engaged with the joining groove (114) formed on the upper or lower side of the sliding groove (113). Since the reinforcing rib (124) and the joining groove (114) each have a T-shaped cross-sectional structure, the joining strength of the side member (120) to the main body (110) can be further improved. Accordingly, the joining portion of the main body (110) and the side member (120) can be prevented from being damaged or deformed due to the weight of the load.
[0054] The first position of the above side member (120) can be fixed by the fastening member (130).
[0055] That is, as illustrated in FIG. 7, when the side member (120) is moved to the first position, the reference fastening hole (132a) of the first fixed bar (132) fixed to the main body (110) and the first fastening hole (133a) of the second fixed bar (133) fixed to the side member (120) are connected to each other, and the fastening screw (131) is fastened to the reference fastening hole (132a) and the first fastening hole (133a), thereby preventing the side member (120) from moving arbitrarily from the first position.
[0056] Meanwhile, since the first fixing bar (132) and the second fixing bar (133) are made of a metal material with excellent durability, the fastening portion (130) can be prevented from being easily worn or damaged during the process of repeatedly fastening and detaching the fastening screw (131).
[0057]
[0058] Among the attached drawings, Figure 8 is an operational diagram showing the process of converting the size-variable assembly pallet of the present invention from the first standard to the second standard.
[0059] As shown in (a) of Fig. 8, when the side members (120) arranged on each side of the main body (110) are moved to a first position close to the main body (110), a pallet of the first specification is provided.
[0060] In a state where the side member (120) has moved to the first position, the reference fastening hole (132a) of the first fixed bar (132) fixed to the main body (110) and the first fastening hole (133a) of the second fixed bar (133) fixed to the side member (120) are connected, and as the fastening screw (131) is fastened to the reference fastening hole (132a) and the first fastening hole (133a), the side member (120) is prevented from moving arbitrarily from the first position.
[0061] In this state, when a transition to the second standard is required, the fastening screw (131) is separated from the reference fastening hole (132a) and the first fastening hole (133a) as shown in (b) of Fig. 8 to release the restraint of the side member (120) to the main body (110).
[0062] Next, as shown in (c) of FIG. 8, the side member (120) is pulled away from the main body (110) to move to a second position, and then, as shown in (d) of FIG. 8, a second standard pallet can be provided by fixing the second position of the side member (120) by fastening a fastening screw (131) to the reference fastening hole (132a) of the first fixing bar (132) and the second fastening hole (133b) of the second fixing bar (133) that are connected to each other at the second position.
[0063] Meanwhile, the transition from the second standard to the first standard is the reverse of the transition process from the first standard to the second standard, so a detailed description thereof is omitted.
[0064]
