Description

Technology Field

[0001] The present invention relates to a pallet using eco-friendly lumber and boards. Background Technology

[0002] Generally, a pallet refers to a flat platform or stand used in warehouses or factories handling various types of cargo. It is used to be packaged together with products loaded for export and stacked inside containers. It is designed to allow for the rapid and convenient transport of large quantities of cargo using means such as forklifts, while simultaneously enabling safe loading and storage.

[0003] Various types of such pallets have been used in the past and are classified according to the materials that constitute the pallet.

[0004] More specifically, they are classified into 1) wooden pallets made of wood, 2) plastic pallets made by molding plastic material, 3) steel pallets made of metal material used for loading heavy products, and 4) foam pallets made of sponge or styrofoam.

[0005] Due to the nature of pallets, heavy products are often transported or stored while loaded for extended periods, so wooden or plastic pallets currently constitute the majority. However, conventional pallets as described above have the following problems.

[0006] For example, in the case of wooden pallets, resources are being depleted day by day, and costs are rising due to the need for separate antibacterial and insecticidal treatments as pests that parasitize the wood are carried along. Furthermore, countries are banning the use and import of wooden pallets, and due to their vulnerability to moisture, their use is currently rapidly declining.

[0007] In addition, plastic pallets have high strength and are not affected by moisture, but they are molded to improve durability, so they are heavy and difficult to handle, and there is a risk that they may be broken by the forks of a forklift, and if they are broken, they are difficult to recycle.

[0008] In addition, steel pallets are difficult to manufacture because each component of the pallet must be secured with a large number of piece bolts, and there are many cases where the pallet is completed with the fixing positions of the piece bolts missing, resulting in the pallet itself becoming a defective product and lacking durability.

[0031] FIG. 1a is a perspective view of a pallet (10) using eco-friendly square timbers (13) and plates (11) according to one embodiment of the present invention, and FIG. 1b is a front view of a pallet (10) using eco-friendly square timbers (13) and plates (11) according to one embodiment of the present invention.

[0032] Referring to FIGS. 1a and 1b, a pallet (10) using an eco-friendly square timber (13) and a plate (11) according to one embodiment of the present invention may include a square timber (13) and a plate (11).

[0033] A pallet (10) made of eco-friendly square timbers (13) and plates (11) can have products or cargo placed on its upper surface, and the pallet (10) with products or cargo placed on it can be transported by means of transport such as a forklift.

[0034] FIG. 3a is a perspective view of a plate (11) in a pallet (10) using eco-friendly square timber (13) and a plate (11) according to one embodiment of the present invention, FIG. 3b is an unfolded view of a plate (11) in a pallet (10) using eco-friendly square timber (13) and a plate (11) according to one embodiment of the present invention, FIG. 3c is a cross-sectional view of a plate (11) in a pallet (10) using eco-friendly square timber (13) and a plate (11) according to one embodiment of the present invention, FIG. 4a is a perspective view of a plate (11) in a pallet (10) using eco-friendly square timber (13) and a plate (11) according to another embodiment of the present invention, FIG. 4b is an unfolded view of a plate (11) in a pallet (10) using eco-friendly square timber (13) and a plate (11) according to another embodiment of the present invention, FIG. 4c is an eco-friendly square timber (13) and a plate (11) using eco-friendly square timber (13) and a plate (11) according to another embodiment of the present invention This is a drawing showing a portion of the cross-section of the plate (11) in the pallet (10).

[0035] Referring to FIGS. 2a to 4c, the plate (11) includes a main body and a cutting part, and the main body can be folded along the cutting part.

[0036] The main body (100) can be formed of paper material, and accordingly, organic solvents are not used, so it is harmless to the human body of the user, and is lighter than conventional timbers (13) made of solid wood or plywood, and can be recycled.

[0037] In addition, since the main body (100) is formed of paper material, damage caused by the forks of a forklift (forklift) during transportation can be minimized.

[0038] The main body (100) can be manufactured by a digital knife cutting method.

[0039] Corrugated cardboard produced using the conventional Thomson press method is manufactured by applying pressure to a wooden mold, so damage and deformation occur where the cut portion is pushed inward due to the pressure, and a large amount of dust is generated during the manufacturing process. In addition, when manufacturing according to the customer's requirements, the existing wooden mold cannot be used, so a new wooden mold must be made to proceed with the work, and if the number of layers of backing paper (110) and corrugated core paper (120) is increased, work efficiency decreases.

[0040] On the other hand, the digital knife cutting method cuts the main body (100) by vibrating the blade at high speed, so that damage to the cut portion of the main body (100) does not occur and less dust can be generated. For example, the main body (100) can be manufactured using a cutting machine with CNC technology. In addition, when manufactured according to the requirements of the customer, the mold making process can be omitted, and manufacturing can be easy even when the number of layers of backing paper (110) and corrugated core paper (120) increases.

[0041] The main body (100) may include a backing paper (110), a core paper (120), and a surface paper (130).

[0042] Here, the backing paper (110) can be positioned to face outward when the main body (100) is folded along the cutting section (200), as shown in FIGS. 3a to 3c.

[0043] As shown in FIGS. 3a to 3c, the corrugated core (120) is attached to the front surface of the backing paper (110) and formed into a corrugated structure, which can produce a cushioning effect that protects against external impact.

[0044] The bone core (120) may be composed of at least one of bone A or bone B.

[0045] For example, A groove may be a corrugated core (120) with a height between 4.6 mm and 4.8 mm, B groove may be a corrugated core (120) with a height between 2.5 mm and 2.8 mm, and E groove may be a corrugated core (120) with a height between 1.2 mm and 1.3 mm.

[0046] In this case, A-flute exhibits superior performance in vertical compressive strength and cushioning compared to other types of corrugated cardboard, but is characterized by poor long-term storage due to its low flute density; B-flute has lower compressive strength and cushioning compared to A-flute but possesses high material strength; and E-flute has lower cushioning but excellent storage properties.

[0047] Depending on the use of the plate material (11), the corrugated core (120) may be composed of A corrugations with a height between 4.6 mm and 4.8 mm or B corrugations with a height between 2.5 mm and 2.8 mm.

[0048] As shown in FIGS. 3a to 3c, the surface paper (130) can be formed and adhered to the other end of the laminated core paper (120) in a shape corresponding to the back paper (110).

[0049] Meanwhile, the backing paper (110) and the corrugated core paper (120) can be stacked sequentially at least once.

[0050] At this time, the backing paper (110) and the core paper (120) can be stacked differently depending on the load applied to the plate (11) to prevent deformation caused by the load applied to the plate (11).

[0051] A plurality of square member grooves (400) may be formed so that a square member (13) can be inserted into the lower part of the main body (100) which is folded along the cutting part (200) in the plate (11).

[0052] For example, as shown in FIGS. 1 to 4, a square member groove (400) is formed in the lower part of the plate (11), so that a square member (13) can be inserted, and the square member (13) can be configured to be press-fitted into the square member groove (400) formed in the plate (11).

[0053] Multiple square grooves (400) can be formed with a depth of 3 mm to 10 mm.

[0054] For example, a plurality of square grooves (400) formed in the lower part of the plate (11) may be formed to a depth of 3 mm to 10 mm so that one back paper (110) and a corrugated core (120) pass through, or two back papers (110) and corrugated core (120) pass through.

[0055] Additionally, the depth of the groove (400) can be formed differently depending on the height of the groove of the core (120) included in the plate (11), and accordingly, the groove (13) combined with the plate (11) can be prevented from being detached or removed due to external impact.

[0056] A plurality of square grooves (400) can be formed at a position spaced apart from the outer surface of the plate (11).

[0057] For example, as shown in FIG. 4, a plurality of square grooves (400) are formed at a position spaced apart from the outer surface of the plate (11), thereby preventing damage to the cutting portion (200) during the manufacturing process of the plate (11).

[0058] Meanwhile, the cutting portion (200) can be cut in a V-shape in the longitudinal direction on the upper surface of the surface paper (130).

[0059] The cutting section (200) can be cut such that the left and right cross-sections are symmetrical and the cutting angle is 90 degrees.

[0060] The cutting portion (200) can be cut to penetrate the surface paper (130) and the core paper (120), as shown in FIG. 3C.

[0061] As the cutting portion (200) is V-cut to penetrate the surface paper (130) and the core paper (120), the main body portion (100) can be folded so that the left and right cross-sections of the cutting portion (200) are connected.

[0062] In this case, as mentioned above, since V-cutting cannot be produced using the conventional Thomson press method, it is preferable to produce it using a digital knife cutting method.

[0063] Meanwhile, the gap between the two ends of the cutting section (200) may be twice the thickness of the surface paper (130) and the corrugated paper (120) so that it can form a right angle when the main body (100) is folded.

[0064] The cutting section (200) may include a first cutting section (210) that cuts a portion of the main body (100) along a first interval (211) that is pre-set inward from both ends of the main body (100), and a second cutting section (220) that cuts a portion of the main body (100) along a second interval (221) that is pre-set inward from the first cutting section (210).

[0065] The first cutting section (210) and the second cutting section (220) each cut a part of the main body (100) along a first gap (211) set inwardly at both ends of the main body (100), so that when the main body (100) is folded along the first cutting section (210) and the second cutting section (220), it is configured as a rectangular cuboid to support a product or plate (11).

[0066] Here, the first gap (211) may be the distance from the end of the main body part (100) to the end of the first cutting part (210).

[0067] The plate (11) can be set so that when the main body (100) is folded, both ends of the main body (100) are positioned at the center of the main body (100).

[0068] For example, the first gap (211) can be set so that when the main body (100) is folded along the first cutting section (210) and the second cutting section (220), both ends of the main body (100) are positioned at the center of the main body (100).

[0069] The second interval (221) may be the distance from the other end of the first cutting section (210) to the first end of the second cutting section (220).

[0070] The second gap (221) may be twice the thickness of the surface paper (130).

[0071] For example, the second gap (221) may be twice the thickness of the surface paper (130) so that when the main body (100) is folded along the first cutting section (210) and the second cutting section (220), the surface paper (130) between the first cutting section (210) at one end can be connected to the surface paper (130) between each of the second cutting sections (220), but is not limited thereto, and may have a gap between the thickness of the surface paper (130) and twice the thickness of the surface paper (130) as shrinkage or deformation may occur due to external force.

[0072] Referring to FIGS. 4a to 4c, in a pallet (10) using an eco-friendly square timber (13) and a plate (11) according to another embodiment of the present invention, when the main body (100) is folded, an internal space is formed in the plate (11), and an auxiliary plate (300) can be inserted into the internal space.

[0073] For example, the auxiliary plate (300) may be formed with the same thickness as the main body (100) and with the same surface area as the surface paper (130) between each second cutting section (220).

[0074] The auxiliary plate (300) can be positioned in contact with the surface paper (130) between each second cutting section (220), and the second gap (221) can be set to the thickness of the auxiliary plate (300) so that when the main body (100) is folded, it can be configured in a rectangular shape.

[0075] In this way, as the auxiliary plate (300) is inserted into the internal space formed when the main body (100) is folded, it can support heavier materials.

[0076] The auxiliary plate (300) can be arranged so that the corrugated structure of the corrugated core (120) of the auxiliary plate (300) and the corrugated structure of the corrugated core (120) of the main body (100) are perpendicular to each other.

[0077] For example, as shown in FIGS. 4a to 4c, the corrugated structure of the corrugated core (120) of the main body (100) is formed in the longitudinal direction, and the corrugated structure of the corrugated core (120) of the auxiliary plate (300) is formed in the transverse direction, so that when a load is applied to the plate (11) into which the corrugated core (120) is inserted in the main body (100), it is possible to prevent bending along the corrugated structure of the corrugated core (120) of the main body (100).

[0078] Meanwhile, referring to FIGS. 3a to 4c, the backing paper (110) and the core paper (120) of the auxiliary plate material (300) can be sequentially laminated at least once.

[0079] The backing paper (110) and the core paper (120) of the auxiliary plate (300) can be laminated differently depending on the load applied to the plate (11) to further prevent deformation caused by the load applied to the plate (11).

[0080] Meanwhile, at least one auxiliary plate (300) may be placed in the internal space formed when the main body (100) is folded.

[0081] For example, an auxiliary plate (300) may be arranged to correspond to the thickness of the main body (100) when the main body (100) is folded. Specifically, when the back paper (110) and the corrugated core (120) of the main body (100) are stacked twice, the thickness of the main body (100) when the main body (100) is folded is the thickness of the back paper (110) and the corrugated core (120) stacked four times. Therefore, the thickness of the auxiliary plate (300) may correspond to the thickness of the main body (100) when the main body (100) is folded. Two auxiliary plates (300) in which the back paper (110) and the corrugated core (120) are stacked twice may be arranged, or one auxiliary plate (300) in which the back paper (110) and the corrugated core (120) are stacked four times may be arranged.

[0082] In another example, when the backing paper (110) and the corrugated core (120) of the main body (100) are stacked three times, the thickness of the main body (100) when the main body (100) is folded is the thickness of the backing paper (110) and the corrugated core (120) stacked six times, so the thickness of the auxiliary plate (300) can be arranged such that the backing paper (110) and the corrugated core (120) are stacked twice and three auxiliary plates (300) are arranged, or the backing paper (110) and the corrugated core (120) are stacked three times and two auxiliary plates (300) are arranged, or the backing paper (110) and the corrugated core (120) are stacked six times and one auxiliary plate (300) is arranged.

[0083] In this way, as the auxiliary plate (300) is arranged to correspond to the thickness of the main body (100) when the main body (100) is folded, it is possible to further prevent the main body (100) and the auxiliary plate (300) from bending when a load is applied to the plate (11).

[0085] Referring to FIGS. 5a to 5c, in a pallet (10) using an eco-friendly square timber (13) and a plate (11) according to one embodiment of the present invention, the square timber (13) includes a main body part (100) and a cutting part (200) as described above, and the main body part (100) can be foldable along the cutting part (200).

[0086] Here, the details regarding the main body (100) of the square timber (13) are the same as the details regarding the main body (100) of the plate (11), so they are omitted.

[0087] Meanwhile, the cutting portion (200) can be cut in a V-shape in the longitudinal direction on the upper surface of the surface paper (130).

[0088] The cutting section (200) can be cut such that the left and right cross-sections are symmetrical and the cutting angle is 90 degrees.

[0089] The cutting portion (200) can be cut to penetrate the surface paper (130) and the core paper (120).

[0090] As the cutting portion (200) is V-cut to penetrate the surface paper (130) and the core paper (120), the main body portion (100) can be folded so that the left and right cross-sections of the cutting portion (200) are connected.

[0091] At this time, the gap between the two ends of the cutting section (200) may be twice the thickness of the surface paper (130) and the corrugated paper (120) so that it can form a right angle when the main body (100) is folded.

[0092] The cutting section (200) may include a first cutting section (210) that cuts a portion of the main body (100) along a first interval (211) set inwardly from both ends of the main body (100).

[0093] The first cutting section (210) can support a product or plate (11) by cutting a portion of the main body (100) along a first interval (211) that is set inwardly at both ends of the main body (100), so that when the main body (100) is folded along the first cutting section (210), it is formed into a rectangular cuboid.

[0094] Here, the first gap (211) may be the distance from the end of the main body part (100) to the end of the first cutting part (210).

[0095] The first gap (211) can be set so that when the main body (100) is folded, one end of the main body (100) comes into contact with the other end of the main body (100).

[0096] Referring to FIGS. 5a to 5c, the cutting section (200) may further include a second cutting section (220) and a third cutting section (230).

[0097] The second cutting section (220) can cut a portion of the main body (100) in the longitudinal direction along a second interval (221) that is set inward from the first cutting section (210).

[0098] Here, the second interval (221) may be the distance from the other end of the first cutting section (210) to the first end of the second cutting section (220).

[0099] The second gap (221) may be twice the thickness of the surface paper (130).

[0100] The second gap (221) may be twice the thickness of the surface paper (130) so that when the main body (100) is folded along the first cutting section (210) and the second cutting section (220), the surface paper (130) between the first cutting section (210) and the surface paper (130) between the second cutting section (220) and the third cutting section (230) can be connected to each other, but is not limited thereto, and for example, since shrinkage or deformation may occur due to a force generated from the outside, it may have a gap between the thickness of the surface paper (130) and twice the thickness of the surface paper (130).

[0101] Meanwhile, the third cutting section (230) can cut a portion of the main body (100) in the longitudinal direction along the third interval (231) set inward from the second cutting section (220).

[0102] Here, the third interval (231) may be the distance from the other end of the second cutting section (220) to the first end of the third cutting section (230).

[0103] The third interval (231) may be the same as the distance of the first interval (211).

[0104] For example, when the main body (100) is folded along the first cutting section (210) and the second cutting section (220), the surface sheet (130) between the first cutting section (210) at one end of the main body (100) can be connected to the surface sheet (130) between the second cutting section (220) and the third cutting section (230) in a corresponding manner, and both sides of the main body (100) can come into contact with the surface sheet (130) between each of the third cutting sections (230).

[0105] Meanwhile, in the square timber (13) using v-cutting according to another embodiment of the present invention, the spacing between each third cutting part (230) may be twice the thickness of the main body part (100).

[0106] For example, when the main body (100) is folded along the first cutting section (210), the second cutting section (220), and the third cutting section (230), the two sides of the main body (100) may be connected to the surface paper (130) between each third cutting section (230) and positioned at the central axis of the main body (100), and the back paper (110) between each of the first cutting section (210) at both ends of the main body (100) may be connected to each other and formed into a rectangular shape.

[0107] At this time, a maximum compression load test is performed on the square timber (13) folded along the first cutting section (210), the second cutting section (220), and the third cutting section (230). As a result of applying force until deformation occurs in the square timber (13) according to one embodiment of the present invention, the values ​​are 698.5 kgf, 730.0 kgf, 696.0 kgf, 704 kgf, and 702.5 kgf. Since it can withstand an average force of 706.2 kgf, it can support a product or plate (11) weighing 706.2 kg or less.

[0108] Referring to FIGS. 6a to 6c, in a pallet (10) using an eco-friendly square timber (13) and a plate (11) according to another embodiment of the present invention, the cutting portion (200) of the square timber (13) may further include a fourth cutting portion (240) and a fifth cutting portion (250).

[0109] The fourth cutting section (240) can cut a portion of the main body (100) in the longitudinal direction along the fourth interval (241) set inward from the third cutting section (230).

[0110] Here, the fourth interval (241) may be the distance from the other end of the third cutting section (230) to the first end of the fourth cutting section (240).

[0111] The fourth gap (241) may be the thickness of the main body (100).

[0112] The fourth gap (241) can be connected so that when the main body (100) is folded along the first cutting section (210), the second cutting section (220), the third cutting section (230), and the fourth cutting section (240), both sides of the main body (100) can be connected to the surface paper (130) between the third cutting section (230) and the fourth cutting section (240).

[0113] Meanwhile, the fifth cutting section (250) can cut a portion of the main body (100) in the longitudinal direction along the fifth interval (251) that is pre-set inward from the fourth cutting section (240).

[0114] The fifth gap (251) may be the same as the gap of the backing paper (110) from one end of the main body (100) to the first cutting part (210) when the main body (100) is folded through the first gap (211).

[0115] For example, when the main body (100) is folded along the first cutting section (210), the second cutting section (220), the third cutting section (230), the fourth cutting section (240), and the fifth cutting section (250), the back paper (110) from one end of the main body (100) to the first cutting section (210) and the surface paper (130) between the fourth cutting section (240) and the fifth cutting section (250) can be connected in a corresponding manner, and the back paper (110) between the first cutting section (210) and the second cutting section (220) can be connected to the surface paper (130) between each of the fifth cutting sections (250).

[0116] Meanwhile, in another embodiment of the present invention, the spacing between each fifth cutting section (250) in the square timber (13) may be twice the thickness of the main body (100).

[0117] For example, when the main body (100) is folded along the first cutting section (210), the second cutting section (220), the third cutting section (230), the fourth cutting section (240), and the fifth cutting section (250), the backing paper (110) between the first cutting section (210) and the second cutting section (220) may be connected to the surface paper (130) between each of the fifth cutting sections (250) and positioned on the central axis of the main body (100), and each backing paper (110) between the second cutting section (220) and the third cutting section (230) may be connected to each other and formed into the shape of a rectangular parallelepiped.

[0118] At this time, a maximum compression load test is performed on the square timber (13) folded along the first cutting section (210), the second cutting section (220), the third cutting section (230), the fourth cutting section (240) and the fifth cutting section (250). As a result of applying force until deformation occurs in the square timber (13) according to another embodiment of the present invention, the results are 993.0 kgf, 1047.0 kgf, 1001.0 kgf, 1018.5 kgf, and 1033.0 kgf. Since it can withstand an average force of 1018.5 kgf, it can support a product or plate (11) weighing 1018.5 kg or less.

[0119] However, this is not limited to this, and the number of folding cycles may decrease or increase depending on the product or cargo placed on the pallet (10).

[0120] Meanwhile, as shown in FIGS. 1a to 1b, the square member (13) may include at least one first square member inserted into a square member groove (400) formed at both lower ends of the plate member (11) and at least one second square member inserted into a square member groove (400) formed at the middle lower end of the plate member (11).

[0121] As the first square member is inserted into both lower ends of the plate (11), the forklift's forks are inserted into the lower part of the plate (11) to lift the pallet (10), and as the second square member is inserted into the middle part of the plate (11), it is possible to prevent bending due to the weight of the product or cargo when the product or cargo is placed on the upper part of the pallet (10).

[0122] Meanwhile, at least two first timbers and two second timbers may be provided.

[0123] As shown in FIGS. 2a and 2b, the first and second square timbers may be inserted into the square timber grooves (400) formed at both ends and the middle of the plate (11), respectively, so that a total of 9 square timbers (13) can be inserted into the lower part of the plate (11), but are not limited thereto. For example, a total of 6 square timbers (13) may be inserted into the square timber grooves (400) formed at both ends of the plate (11), respectively.

[0124] The plate (11) can be positioned so that the main body (100) folded along the cutting section (200) faces downward, and the square member (13) can be positioned so that the main body (100) folded along the cutting section (200) faces upward.

[0125] For example, as shown in FIGS. 1a to 2b, the plate (11) is positioned so that the main body (100) folded along the cutting section (200) faces downward, thereby preventing the adhesive portion between the main body (100) from opening when the plate (11) is folded and improving the aesthetic appeal of the pallet (10).

[0126] In addition, as shown in FIGS. 1a to 2b, the lumber (13) is positioned so that the main body (100) folded along the cutting section (200) faces upward, thereby preventing the adhesive portion between the main body (100) from opening when the lumber (13) is folded.

[0127] As described above, the pallet (10) using the eco-friendly square timber (13) and plate (11) according to one embodiment of the present invention is composed of backing paper (110), corrugated core paper (120), and surface paper (130), so it is lightweight, has excellent processability, and improves work efficiency. It also includes a cutting section (200) that is cut in a V-shape in the longitudinal direction on the upper surface of the main body (100), and since the main body (100) is configured to be foldable along the cutting section (200), the manufacturing process is very simple, so manufacturing costs can be reduced, the weight of the pallet (10) is very light, so transportation costs can be reduced, and contamination and deformation of the outer part of the pallet (10) can be minimized.

[0128] In addition, the main body (100) of the plate (11) and square (13) included in the pallet (10) is manufactured by a digital knife cutting method, so that no damage occurs to the cut portion of the main body (100) and less dust is generated, and when manufactured according to the requirements of the orderer, the process of making a wooden mold can be omitted, and even when the number of layers of backing paper (110) and corrugated paper (120) increases, manufacturing can be easy.

[0129] In addition, since the backing paper (110) and the corrugated core paper (120) are stacked sequentially at least once, the number of stackings is varied according to the load applied to the pallet (10), thereby preventing deformation caused by the load applied to the pallet (10).

[0130] The description of the present invention given above is for illustrative purposes only, and those skilled in the art will understand that other specific forms can be easily modified without altering the technical spirit or essential features of the present invention. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive.
