Description

PALLETS USING ECO-FRIENDLY TRAYS AND LUMBER

The present invention relates to an eco-friendly tray and a pallet using lumber.

In general, tray-type pallets are used in warehouses and factories that handle various types of cargo, and are configured in the form of a box with an open top, and are used to be packed together with products to be loaded onto a shipment for export and stacked inside a container. They are a type of support configured to enable the quick and easy transport of large quantities of cargo using a means of transportation such as a forklift, while also safely loading and storing them.

These palettes have been used in various types in the past and are classified according to the material they are made of.

Specifically, they are classified into 1) wooden pallets made of wood, 2) plastic pallets made of plastic material, 3) steel pallets made of metal material used to load heavy products, and 4) foam pallets made of sponge or Styrofoam.

Due to the nature of pallets, they are often used for long-term transport or storage with heavy products loaded on them, so most pallets are made of wood or plastic. However, the above-mentioned conventional pallets have the following problems.

For example, in the case of wooden pallets, the resource is being depleted day by day, and since pests that parasitize the wood move with it, the cost increases due to separate anti-bacterial and anti-insect treatment, and the use and import of wooden pallets are prohibited in each country, and their use is currently rapidly decreasing due to their vulnerability to moisture.

In addition, in the case of plastic pallets, although they are strong and unaffected by moisture, they are heavy and difficult to handle because they are molded to improve durability, and there is a risk of them being broken by the forklift's leg, and if they are broken, there is a problem that they are difficult to recycle.

In addition, steel pallets are not easy to manufacture because each component of the pallet must be fixed 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 being defective and lacking durability.

FIG. 1 is a perspective view of a pallet (10) using an eco-friendly tray and lumber according to one embodiment of the present invention, FIG. 2 is an exploded perspective view of a pallet (10) using an eco-friendly tray and lumber according to one embodiment of the present invention, FIG. 3 is a plan view of a pallet (10) using an eco-friendly tray and lumber according to one embodiment of the present invention, FIG. 4a is a front view of a pallet (10) using an eco-friendly tray and lumber according to one embodiment of the present invention when a tray (11) is unfolded, FIG. 4b is a front view of a pallet (10) using an eco-friendly tray and lumber according to one embodiment of the present invention when a tray (11) is folded, and FIG. 4c is a cross-sectional view of a tray (11) of a pallet (10) using an eco-friendly tray and lumber according to one embodiment of the present invention.

Referring to FIGS. 1 to 4c, a pallet (10) using an eco-friendly tray and lumber according to one embodiment of the present invention may include a tray (11) and lumber (13).

A pallet (10) using an eco-friendly tray and lumber can have products or cargo loaded inside, and a tray (11) loaded with products or cargo can be transported using a means of transportation such as a forklift.

Referring to FIGS. 1 and 2, the tray (11) includes a main body (100) and a cutting portion (200), and can be folded along the cutting portion (200).

The main body (100) can be formed of paper material, and therefore, no organic solvent is used, making it harmless to the user's human body, lighter than a tray (11) made of conventional wood or plywood, and can be recycled.

In addition, since the main body (100) is formed of paper material, damage during transportation can be minimized.

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

Since corrugated cardboard manufactured using the conventional Thompson press method is manufactured by applying pressure to a mold, damage and deformation occur due to the cut portion being pressed inward by the pressure, and many chips are generated during the manufacturing process. In addition, since the existing mold cannot be used when manufacturing according to the customer's requirements, the necessary mold must be newly manufactured and work must be done, and if the number of layers of the backing paper (101) and the corrugated paper (103) is increased, work efficiency decreases.

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 scrap is generated. For example, the main body (100) can be manufactured using a cutting machine to which CNC technology is applied. In addition, when manufacturing according to the customer's requirements, the mold manufacturing process can be omitted, and manufacturing can be easy even when the number of times the backing paper (101) and the core paper (103) are laminated increases.

The main body (100) may include a double-sided paper (101), a core paper (103), and a surface paper (105).

Here, the double-sided paper (101) can be positioned to face the outside when the main body (100) is folded along the cutting portion (200).

The core (103) is adhered to the front surface of the backing paper (101) and formed into a wave-shaped structure, thereby generating a buffering effect that can protect against external impact.

The bone core (103) may be composed of at least one of the A bone or the B bone.

For example, the A-goal may be a core (103) having a height of between 4.6 mm and 4.8 mm, the B-goal may be a core (103) having a height of between 2.5 mm and 2.8 mm, and the E-goal may be a core (103) having a height of between 1.2 mm and 1.3 mm.

At this time, A flute shows superior performance in vertical compressive strength and cushioning properties compared to other flute types of corrugated board, but has the characteristic of being weak in long-term storage due to its low flute density, B flute has lower compressive strength and cushioning properties compared to A flute, but has the characteristic of having high material strength, and E flute has lower cushioning properties but has the characteristic of having excellent storage properties.

Depending on the purpose for which the board is used, the flute (103) can be composed of an A flute having a flute height of 4.6 mm to 4.8 mm or a B flute having a flute height of 2.5 mm to 2.8 mm.

The surface paper (105) can be bonded to the other end of the laminated core paper (103) in a shape corresponding to the back paper (101).

Meanwhile, the double-sided paper (101) and the core paper (103) can be sequentially laminated at least once.

At this time, the double-sided paper (101) and the corrugated paper (103) can be laminated at different numbers depending on the load applied to the main plate (110) to prevent deformation from occurring due to the load applied to the main plate (110).

Meanwhile, the cutting section (200) can be cut in a V shape longitudinally on the upper surface of the surface paper (105).

The cutting section (200) can be cut so that the left and right cross sections are symmetrical and the cutting angle is 90 degrees.

The cutting section (200) can be cut to penetrate the surface paper (105) and the core paper (103), as shown in FIGS. 4a and 4c.

As the cutting section (200) is V-cut to penetrate the surface paper (105) and the core paper (103), the main body (100) can be folded so that the left and right cross sections of the cutting section (200) are connected.

At this time, since V-cutting cannot be produced using the conventional Thompson press method as described above, it is preferable to produce it using a digital knife cutting method.

The gap between the two ends of the cutting section (200) may be twice the thickness of the surface paper (105) and the core paper (103) so that the main body (100) can form a right angle when folded.

The tray (11) may include a main plate (110) and a side wall portion (120).

The main plate (110) is configured in a rectangular shape and at least one fixing groove (111) can be formed at each end.

The upper part of the main plate (110) is where the product or cargo is placed, and the number of times the backing paper (101) and the corrugated paper (103) are laminated can vary depending on the load applied to the main plate (110).

As shown in Fig. 3, three fixed grooves (111) are formed at regular intervals at each end, and protrusions (121) formed on the side wall portion (120) are inserted into them, thereby preventing the side wall portion (120) from moving left and right due to products or cargo loaded inside the tray (11). However, this is not limited thereto, and for example, the number of fixed grooves (111) may vary depending on cargo loaded on the tray (11).

The side wall portion (120) may be formed to extend in one direction from each end of the main plate (110), and a protrusion (121) may be formed to correspond to the fixing groove (111).

As shown in FIGS. 1 to 3, a cutting portion (200) is formed between the main plate (110) and the side wall portion (120), so that the side wall portion (120) can be folded along the cutting portion (200).

In addition, since a cutting portion (200) is formed along a first interval set on both sides from the middle portion of the side wall portion (120), the side wall portion (120) can be folded in two stages along the cutting portion (200).

When the side wall portion (120) is folded in two stages along the cutting portion (200), the protrusion portion (121) is formed to correspond to the fixing groove (111) and is inserted into the fixing groove (111) formed in the main plate (110), thereby preventing the side wall portion (120) from moving left and right due to the product or cargo loaded inside the tray (11).

In an eco-friendly tray and a pallet (10) using lumber according to one embodiment of the present invention, the lumber (13) includes a main body (100) and a cutting section (200), as described above, and the main body (100) can be folded along the cutting section (200).

Here, the content of the main body (100) of the lumber (13) is the same as the content of the main body (100) of the tray (11), so it will be omitted.

FIG. 5a is a perspective view of a two-stage folded lumber (13) in a pallet (10) using an eco-friendly tray and lumber according to one embodiment of the present invention, FIG. 5b is an expanded view of a two-stage folded lumber (13) in a pallet (10) using an eco-friendly tray and lumber according to one embodiment of the present invention, and FIG. 5c is a cross-sectional view of a two-stage folded lumber (13) in a pallet (10) using an eco-friendly tray and lumber according to one embodiment of the present invention.

Referring to FIGS. 5a to 5c, both ends of the lumber (13) can be folded in two stages along the cutting portion (200).

For example, when the length of the two-folded lumber (13) is 100 mm, the maximum compressive load test is performed and the force applied until deformation occurs in the lumber (13) is 698.5 kgf, 730.0 kgf, 696.0 kgf, 704 kgf, and 702.5 kgf, so it can withstand an average force of 706.2 kgf, and therefore can support a product or tray (11) weighing 706.2 kg or less.

FIG. 6a is a perspective view of a three-stage folded lumber (13) in a pallet (10) using an eco-friendly tray and lumber according to one embodiment of the present invention, FIG. 6b is an expanded view of a three-stage folded lumber (13) in a pallet (10) using an eco-friendly tray and lumber according to one embodiment of the present invention, and FIG. 6c is a cross-sectional view of a three-stage folded lumber (13) in a pallet (10) using an eco-friendly tray and lumber according to one embodiment of the present invention.

Referring to FIGS. 6a to 6c, both ends of the lumber (13) can be folded in three stages along the cutting portion (200).

For example, when the length of the three-folded lumber (13) is 100 mm, the maximum compressive load test is performed and the force applied until deformation occurs in the lumber (13) is 993.0 kgf, 1047.0 kgf, 1001.0 kgf, 1018.5 kgf, and 1033.0 kgf, so it can withstand an average force of 1018.5 kgf and can therefore support a product or tray (11) weighing 1018.5 kg or less.

For another example, when the length of the three-folded lumber (13) is 200 mm, a maximum compressive load test is performed and the force applied to the lumber (13) according to another embodiment of the present invention before deformation occurs is as a result of 1498.5 kgf, 1521.0 kgf, 1509.0 kgf, 1578.5 kgf, and 1600.5 kgf, so that the average force of 1541.5 kgf can be withstood, and therefore a product or tray (11) weighing 11541.5 kg or less can be supported.

In this way, as the length of the lumber (13) increases or the number of times the lumber is folded increases, a heavy product can be supported, so the length of the lumber (13) and the number of times the lumber is folded can be changed according to the weight of the product or cargo so that it can be combined with the tray (11).

However, this is not limited to this, and the number of folding times may be reduced or increased depending on the product or cargo placed on the pallet (10).

Meanwhile, the lumber (13) may include at least one first lumber bonded to the lower ends of the tray (11) and at least one second lumber bonded to the lower middle portion of the tray (11), as shown in FIGS. 1 and 2.

As the first angle lumber is bonded to the lower ends of the tray (11), the forklift's forklift leg can be inserted into the lower end of the tray (11) to lift the pallet (10), and as the second angle lumber is bonded to the middle of the tray (11), when a product or cargo is placed on the upper end of the tray (10), bending due to the weight of the product or cargo can be prevented.

Meanwhile, at least two first and second angle lumbers may be provided.

As shown in FIGS. 1 and 2, the first and second lumbers may be bonded to each end and middle portion of the tray (11), respectively, so that a total of nine lumbers (13) may be bonded to the lower portion of the tray (11), but this is not limited thereto. For example, six lumbers (13) may be bonded to each end and middle portion of the tray (11), respectively, so that a total of six lumbers (13) may be bonded to the lower portion of the tray (11).

The lumber (13) can be placed so that the main body (100) folded along the cutting section (200) faces upward.

For example, as shown in FIGS. 1 and 2, when the lumber (13) is folded along the cutting section (200), the main body (100) is placed so that it faces upward, so that the bonding portion between the main body parts (100) can be prevented from being opened.

The main body (100) may include a plurality of reinforcing members (130) that extend along both sides of the side wall (120) and are inserted into the interior of the side wall (120) when the side wall (120) is folded.

As shown in Fig. 3, the reinforcing member (130) is preferably formed on both sides of the side wall member (120) of the longer length among the horizontal and vertical lengths of the main plate (110), but is not limited thereto, and may be formed on both sides of all the side wall members (120).

As shown in FIG. 3, the width of the reinforcing member (130) can be formed to be the same as the width when the side wall member (120) is folded in two stages along the cutting member (200) so that it can be inserted into the interior of the side wall member (120) when the side wall member (120) is folded.

When a plurality of reinforcing members (130) are inserted into the interior of the side wall member (120), they may further include a connecting member (131) that connects the facing reinforcing members (130).

At this time, as shown in Fig. 3, a catch portion that is recessed inward is formed at the ends of the plurality of reinforcing members (130), and both ends of the connecting member (131) are protruded to correspond to the catch portion, so that the reinforcing members (130) facing each other can be connected.

In this way, by further including a connecting member (131) connecting the facing reinforcing members (130) inserted into the interior of the side wall portion (120), the side wall portion (120) can be further prevented from moving left and right due to a product or cargo loaded inside the tray (11).

Referring to FIG. 2, an eco-friendly tray and pallet (10) using lumber according to one embodiment of the present invention may further include a first auxiliary plate (140) mounted on top of a main plate (110).

For example, the first auxiliary plate (140) is configured to have the same thickness as the main plate (110), and as the first auxiliary plate (140) is inserted into the inside of the tray (11), it can support a heavier product or cargo.

The first auxiliary plate (140) can be arranged so that the corrugation structure of the core (103) of the first auxiliary plate (140) and the corrugation structure of the core (103) of the main plate (110) are perpendicular to each other.

For example, since the corrugation structure of the core (103) of the main plate (110) is formed in the longitudinal direction and the corrugation structure of the core (103) of the first auxiliary plate (140) is formed in the transverse direction, when a load is applied to a tray (11) on which the first auxiliary plate (140) is secured to the main plate (110), the corrugation structure (103) of the main plate (110) can be prevented from bending along the corrugation structure.

Meanwhile, the backing paper (101) and the core paper (103) of the first auxiliary plate (140) can be sequentially laminated at least once.

The backing paper (101) and the corrugated paper (103) of the first auxiliary plate (140) can be laminated in different numbers depending on the load applied to the tray (11) to further prevent deformation due to the load applied to the tray (11).

Referring to FIG. 2, an eco-friendly tray and pallet (10) using lumber according to one embodiment of the present invention may further include a second auxiliary plate (150) mounted on top of a first auxiliary plate (140).

For example, the second auxiliary plate (150) is configured to have the same thickness as the main plate (110), and as the second auxiliary plate (150) is inserted into the inside of the tray (11), it can support a heavier product or cargo.

The second auxiliary plate (150) can be arranged so that the corrugated structure of the core (103) of the second auxiliary plate (150) and the corrugated structure of the core (103) of the first auxiliary plate (140) are perpendicular to each other.

For example, since the corrugation structure of the core (103) of the main plate (110) is formed in the longitudinal direction, the corrugation structure of the core (103) of the first auxiliary plate (140) is formed in the transverse direction, and the corrugation structure of the core (103) of the second auxiliary plate (150) is formed in the longitudinal direction, when a load is applied to a tray (11) on which the first auxiliary plate (140) and the second auxiliary plate (150) are secured to the main plate (110), the corrugation structure (103) of the main plate (110) can be prevented from being bent along the corrugation structure.

Meanwhile, the backing paper (101) and the core paper (103) of the second auxiliary plate can be sequentially laminated at least once.

The backing paper (101) and the corrugated paper (103) of the second auxiliary plate can be laminated at different numbers depending on the load applied to the tray (11) to further prevent deformation caused by the load applied to the tray (11).

FIG. 7a is an exploded perspective view of a pallet (10) using an eco-friendly tray and lumber according to another embodiment of the present invention, and FIG. 7b is a plan view of a pallet (10) using an eco-friendly tray and lumber according to another embodiment of the present invention.

In another embodiment, in an eco-friendly tray and pallet (10) using lumber, a plurality of lumber grooves (113) may be formed in the lower part of the main board (110) so that lumber (13) can be inserted.

For example, as shown in FIGS. 7a and 7b, a lumber groove (113) may be formed at the lower portion of the main plate (110) so that a lumber (13) may be inserted. At this time, the lumber (13) may be bonded to the first auxiliary plate (140) mounted on the upper portion of the main plate (110), or may be configured as a force-fit joint in the lumber groove (113) formed in the main plate (110).

FIG. 8a is an exploded perspective view of a pallet (10) using an eco-friendly tray and lumber according to another embodiment of the present invention, FIG. 8b is a plan view of a pallet (10) using an eco-friendly tray and lumber according to another embodiment of the present invention, and FIG. 8c is a plan view of a second auxiliary board in a pallet (10) using an eco-friendly tray and lumber according to another embodiment of the present invention.

Referring to FIGS. 7 to 9, an eco-friendly tray and pallet (10) using lumber according to another embodiment of the present invention may further include a second auxiliary plate (150) mounted on the lower portion of a main plate (110).

At this time, the second auxiliary plate (150) can be arranged so that the corrugation structure of the core (103) of the second auxiliary plate (150) and the corrugation structure of the core (103) of the main plate (110) are perpendicular to each other.

For example, since the corrugation structure of the core (103) of the main plate (110) is formed in the longitudinal direction and the corrugation structure of the core (103) of the first auxiliary plate (140) and the second auxiliary plate (150) is formed in the transverse direction, when a load is applied to the tray (11) on which the first auxiliary plate (140) and the second auxiliary plate (150) are secured to the main plate (110), the corrugation (103) of the main plate (110) can be prevented from being bent along the corrugation structure.

For example, as shown in FIGS. 5 and 6, a plurality of lumber grooves (151) are formed in the lower portion of the second auxiliary plate (150), into which lumber (13) can be inserted. At this time, the lumber (13) can be bonded to the main plate (110) or configured as a forced fit in the lumber grooves (151) formed in the second auxiliary plate (150).

As described above, the eco-friendly tray and pallet (10) using lumber according to one embodiment of the present invention is composed of a backing paper (101), a corrugated paper (103), and a surface paper (105), and thus is lightweight and has excellent processability, thereby improving work efficiency. In addition, since the upper surface of the main body (100) includes a cutting portion (200) that is vertically V-cut, and the main body (100) is configured to be foldable along the cutting portion (200), the manufacturing process is very simple, thereby reducing the manufacturing cost. In addition, since the weight of the tray (11) is very light, transportation costs can be reduced, and contamination and deformation of the outer surface of the tray (11) can be minimized.

In addition, since the tray (11) and the lumber (13) are manufactured by a digital knife cutting method, damage to the cut portion of the main body (100) does not occur, less waste may occur, the mold manufacturing process can be omitted when manufacturing according to the customer's requirements, and manufacturing can be easy even when the number of times the backing paper (101) and the corrugated paper (103) are laminated increases.

In addition, since the backing paper (101) and the core paper (103) are sequentially laminated at least once, the number of times of lamination is varied depending on the load applied to the pallet (10), so that deformation can be prevented from occurring due to the load applied to the pallet (10).

In addition, since the plurality of reinforcing members (130) extending along both sides of the side wall portion (120) and inserted into the interior of the side wall portion (120) when the side wall portion (120) is folded, and the plurality of reinforcing members (130) further include a connecting member (131) that connects the reinforcing members (130) facing each other when inserted into the interior of the side wall portion (120), the side wall portion (120) can be further prevented from moving left and right due to products or cargo loaded inside the pallet (10).

The description of the present invention described above is for illustrative purposes, and those skilled in the art to which the present invention pertains will understand that it can be easily modified into other specific forms without changing the technical idea or essential features of the present invention. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive. For example, each component described as a single type may be implemented in a distributed manner, and likewise, components described as distributed may be implemented in a combined form.

In addition, the scope of the present invention is indicated by the claims described below rather than the above detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalent concepts should be interpreted as being included in the scope of the present invention.
