Description

FOLDING PALLET FOR EXPORT

The present invention relates to a pallet used when storing or transporting an object to be loaded or transported, and more particularly, to a technology for a folding pallet for export that can be folded to minimize its size and thus significantly reduce the packaging volume when exporting.

In general, in production sites and warehouses for various goods, when loading or transporting raw materials, semi-finished products or finished products, the goods are stored by placing them on pallets as a support (or loading platform), or the goods loaded on pallets are transported together with the pallets using a transport means such as a forklift.

Pallets like these are designed to have a certain strength so that they can support cargo weights ranging from hundreds of kilograms (kg) to several tons, and research and efforts are actively being conducted to reduce the weight while maintaining the strength.

The technology for these palettes is:

Korean Patent Registration No. 10-0987566 (registered on October 6, 2010, hereinafter referred to as 'Document 1') discloses an 'assembly-type pallet'.

Document 1 comprises a bracket in which a first connecting portion is formed longitudinally in a vertical member having an insertion space formed by an insertion plate on an upper surface or a lower surface, a second connecting portion having the same shape as the first connecting portion is formed longitudinally on a lower surface, and a square upper connecting plate and a lower connecting plate are inserted into the insertion space of the first connecting portion and the insertion space of the second connecting portion to orthogonally connect the horizontal members above or below the vertical members, and are separated by a pillar plate. At this time, the internal empty space of the vertical member is formed as a lattice-shaped square frame, a circular frame is formed longitudinally on the central axis of the vertical member, ribs extending to the square frame are formed on all sides of the circular frame, and among the square frames, ribs, or square bars and round bars that intersect each other can be inserted into the inside of the side square frames to enhance durability. In addition, an installation groove is formed on an edge line of the upper surface of the horizontal member in which the head of a bolt is buried upside down, so that the head of the bolt buried upside down is This is a technology for an assembly pallet in which a number of protrusions are formed on the inner surface of a first joint portion, a second joint portion, and a bracket so that a wall member can be joined to a screw portion and assembled in a box shape, thereby eliminating a gap due to tolerance and preventing separation between members.

As another technology, the Republic of Korea Patent Registration No. 10-1810977 (registered on December 14, 2017, hereinafter referred to as 'Document 2') 'Assembly-type steel pallet' is presented.

Document 2 is a technology regarding an assembly-type steel pallet, which comprises an outer frame in the shape of the letter 'ㅁ' having a plurality of joining grooves formed on the upper or lower surface, an upper plate and a lower plate including a plurality of horizontal members and vertical members installed so as to intersect each other on the inner side of the outer frame, and a supporting member in the shape of a round bar that is connected and installed between the joining grooves formed on the outer frames of the upper and lower plates to support the upper plate, thereby minimizing the weight of the pallet formed by combining steel frames while reinforcing the supporting force, and at the same time having a simple structure that is easy to assemble and disassemble so that it can be directly combined and used on site.

Another technology is presented in Korean Patent Registration No. 10-1976485 (registered on May 2, 2019, hereinafter referred to as “Document 3”), titled “Palette for Easy Disassembly and Assembly and Transport Loading.”

Document 3 is a technology regarding a pallet that is easy to assemble and disassemble and transport, including a lower plate that is supported by contacting a floor surface, a plurality of columns whose lower sides are fit-joined to the lower plate, a middle plate whose upper sides of the columns are fit-joined so as to be parallel to the lower plate, and an upper plate that is installed orthogonal to the middle plate, wherein the columns are integrally formed by male-female joints between a first column and a second column, and the first and second columns are configured such that an outer joint piece is folded and formed at one end and an inner joint piece is folded and formed at the other end, so that a double support that reinforces vertical strength is provided by the fit-joint between the outer joint piece of the first column and the inner joint piece of the second column and the fit-joint between the inner joint piece of the second column and the outer joint piece of the second column, thereby making it easy to assemble and disassemble for easy shipment during export, and minimizing the loading volume of parts so as to increase the export shipment volume.

As in Documents 1 to 3 consisting of the above configurations, an assembly-type pallet has been developed in which each part of the pallet is individually packaged, transported, stored, and exported, and then assembled and used locally or at the place of use. However, not only is its structure complex, but if the pallet itself is exported, a large quantity cannot be shipped at one time, so the packaging cost and transportation cost according to the packaging volume increase, and the unit price of the product increases, which not only places an economic burden on local end users, but also makes it impossible to increase the export volume in line with the development of the country's export industry, and so there are various problems.

Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are only the most preferred embodiments of the present invention and do not represent all of the technical idea of the present invention, and it should be understood that there may be various equivalents and modified examples that can replace them at the time of filing this application.

Based on Figure 2, the bottom floor side is designated as the lower or downward direction, and the post side is designated as the upper or upward direction.

As shown in Figures 1 to 11, the folding pallet for export according to the present invention,

It is largely composed of a bottom floor (10), a support block (20), a post (30), a link (40), and a holding means (50).

Let's look at each configuration:

The above bottom floor (10)

As shown in Figures 1 to 3,

It is designed to have a square structure so that the fork of the forklift is inserted and supported, and the load can be placed on top.

At this time, it can be implemented as a square board, but to make it lightweight and easy to assemble, it can also be implemented by arranging two or more long blocks on the left and right to form a square. Each block arranged in this way is connected and fixed to each other by the support block (20).

The above support block (20)

As shown in Figures 1 to 3,

The bottom floor (10) is formed as a long block structure in the front and rear to support the bottom floor (10) while being spaced from the ground, and a plurality of blocks are provided by being arranged in an intersecting manner for each block forming the bottom floor (10).

At this time, the bottom floor (10) and each support block (20) can be mutually assembled by bolting or the like.

The above post (30)

As shown in Figures 1 to 5 and Figures 8 to 10,

It is arranged in the four corner areas of the bottom floor (10) and is composed of an upright column structure, and is provided in multiple pieces. In particular, at least four pieces are provided so that they can be arranged in each of the four corner areas of the bottom floor (10), and additional pieces may be provided between them depending on the type or size of the loaded goods.

And as shown in Fig. 5, a rail line (31) is formed in each of the posts (30) into which the flange (41) is inserted to slide up and down, and a number of adjustment holes (32) are formed in each of the posts (30) at a certain interval up and down and penetrating from the outer wall to the rail line (31).

The above link (40)

As shown in Figures 4 to 8,

This is for connecting the posts (30) facing each other among the above posts (30).

It is composed of a bar structure and is provided with a plurality of them. In particular, when at least four of the above posts (30) are provided by connecting the posts (30) facing each other among the above posts (30), at least two links (40) can be provided, and at this time, as in FIG. 10, two or more links (40) can be provided above and below two facing posts (30).

At this time, as shown in FIGS. 4 and 6, each link (40) is composed of two link parts (40A, 40B) that are rotatably connected by a hinge. As a result, the two link parts (40A, 40B) can be rotated based on the hinge, and can be folded at a certain angle for storage and packaging.

And as shown in Fig. 6, in each link (40), a stopper (43) is formed at the end of one link body (40B) among the two link bodies (40A, 40B) hinge-coupled to each other to limit the rotation angle in the clockwise or counterclockwise direction when the other link body (40A) rotates. At this time, since the stopper (43) is formed with a structure inclined at a certain angle, it can stably support the other link body (40A) that is rotated.

And as shown in FIGS. 4 and 6, a flange (41) is formed at both ends of the two link parts (40A, 40B) of each link (40) so as to be inserted so as to slide up and down along the rail line (31).

In addition, as shown in Fig. 5, a spiral groove (42) is formed in the flange (41) to which a bolt passing through one of the adjustment holes (32) is fastened. As a result, it is possible to adjust the height of the link (40) up and down on the post (30), as well as fix it and release it after the adjustment is completed.

The above holding means (50)

As shown in Figures 2 and 3,

For mutually connecting and separating the bottom of the above bottom floor (10) and the bottom of the above post (30),

A top insert home (51A) formed downwardly in the four corner areas of the bottom floor (10) above,

In each of the above support blocks (20), a bottom insert home (51B) is formed in a lower area of the top insert home (51A) so as to be eccentrically inserted downward while being in vertical communication with the top insert home (51A).

An insert (52) formed at the bottom of each of the above posts (30) and inserted in a form that occupies the top insert home (51A) and the bottom insert home (51B),

A recess (53A) formed inside the bottom floor (10) so as to be open toward the post (30),

A slider (54) arranged to slide in the above recess (53A),

An extension recess (53B) formed to be inserted into the inner wall of the above recess (53A),

A guide (55) connected to the above slider (54) and inserted into the above extension recess (53B),

A spring (56) interposed between the inner wall of the recess (53A) and the slider (54) and exerting elasticity toward the slider (54),

A pin insertion hole (57A) that passes through the upper and lower parts in a form that intersects the extension recess (53B) in the bottom floor (10).

A corresponding pin insertion hole (57B) that penetrates upward and downward at a position corresponding to the pin insertion hole (57A) in the above guide (55),

A holding pin (58) inserted into the corresponding pin insertion hole (57B) through the above pin insertion hole (57A), and

A holding hole (59) formed in the insert (52) so that the end of the slider (54) is inserted when the spring (56) that was compressed is restored when the holding pin (58) is removed and the slider (54) moves forward.

It consists of including:

At this time, as in [B] of Fig. 3, the insert (52) can maintain a more stable standing state as some areas are supported by the upper surface of the support block (20) while being inserted and seated in the top and bottom insert homes (51A, 51B).

Therefore, as in [A] of FIG. 3, when the slider (54) is fixed using the holding pin (58), the insert (52) is inserted into the top and bottom insert holes (51A, 51B), and the holding pin (58) is removed from the pin insertion hole (57A) and the corresponding pin insertion hole (57B), the slider (54) moves forward by the restoring force of the compressed spring (56), so that the end of the slider (54) is inserted into the holding hole (59), and thus the movement of the post (30) is limited.

Meanwhile, the folding pallet for export according to the present invention further includes a locking means (60).

The above locking means (60)

As shown in Figures 6 and 7,

A pair of U-shaped grooves (61) formed downwardly on both sides of the end of one of the two link bodies (40A, 40B) hinged to each other in each link (40),

A pair of locking heads (62) that are hinge-joined to the end of the other link body (40A) among the two link bodies (40A, 40B) that are hinge-joined to each other in each link (40) above and are inserted and seated in the U-shaped groove (61) when rotating, and

A locking pin (63) inserted through the outer wall of the U-shaped groove (61) above, through each locking head (62), and into the U-shaped groove (61) on the opposite side.

It consists of including:

Finally, by positioning and fixing the link (40) at an appropriate position on the post (30), and then inserting and settling the pair of locking heads (62) into the pair of U-shaped grooves (61) by rotating them, and fixing them using the locking pin (63), the rotational motion at the hinge area between the two link parts (40A, 40B) forming the link (40) can be restricted, so that the unfolded state of the two link parts (40A, 40B) can be maintained.

Meanwhile, the folding pallet for export according to the present invention further includes a sub-link (70).

The above sub-link (70)

As shown in Figures 8 to 11,

A sub-insert (71) that is slidably inserted along the above rail line (31),

A subbody (72) connected to the above sub-insert (71),

A sub-load (73) hinge-connected to the above sub-body (72),

A support member (74) that protrudes from the above sub-body (72) and supports the above sub-load (73) that is spread out horizontally.

A downwardly inclined path portion (75) in the direction in which the sub-load (73) is spread inside the above sub-body (72), and

A spherical weight (76) built to move along the above path (75)

It consists of several pieces, including:

And as shown in FIGS. 9 and 10, the path portion (75) is formed so that the center point of the weight (76) can be arranged to be eccentric to one side and the other side from the hinge center point between the sub-body (72) and the sub-rod (73) at the two end stop positions where the weight (76) performs a rolling motion and stops. In other words, as shown in FIG. 9, since the center point of the weight (76) at the position where the weight (76) stops is eccentric to one side compared to the center point of one end of the path portion (75), the upright state can be maintained without a separate external force, and as shown in FIG. 10, since the center point of the weight (76) at the position where the weight (76) stops is eccentric to the other side compared to the center point of the other end of the path portion (75), the horizontal state can be maintained without a separate external force. By using the sub-load (73) capable of operating in this manner, the goods loaded on the bottom floor (10) can be supported more stably, and in particular, the number of sub-links (70) can be appropriately selected depending on the type or size of the goods loaded.

Meanwhile, the folding pallet for export according to the present invention further includes a relay means (80).

The above relay means (80)

As shown in Fig. 11,

A fitting groove (81) formed so as to be inserted into the end of each sub-rod (73) that is spread in the direction facing each other among the sub-links (70) above,

A guide groove (82) that is connected to the above fitting groove (81) and is open upward,

Two relay bodies (83) of the telescope type, and

A relay spring (84) interposed between the two relay particles (83) and exerting elasticity toward one of the relay particles (83)

It consists of including:

Eventually, as in [B] of Fig. 11, the two relay powders (83) are pressed in the direction facing each other to compress the relay spring (84), and then each end of the two relay powders (83) are inserted into the guide groove (82) and moved toward the insertion groove (81), so that the two relay powders (83) move in the opposite direction of the pressing by the restoring force of the relay spring (84) and are inserted toward the inner wall of the insertion groove (81), thereby connecting the two sub-links (70) facing each other. The two relay powders (83) together with the sub-rods (73) of the two sub-links (70) connected in this way can more stably support the goods loaded on the bottom floor (10).

Meanwhile, in the folding pallet for export according to the present invention, a coating layer can be formed using a coating composition so as to exhibit anti-slip and anti-rust effects on the surface of the bottom floor (10) or the post (30), or both.

The coating composition comprises 60 to 70 parts by weight of an acrylic resin (polypropylene, PP), 30 to 40 parts by weight of butadiene rubber (BR), 20 to 30 parts by weight of acrylic acid, 10 to 20 parts by weight of silicate, 5 to 10 parts by weight of aluminum flakes, 5 to 10 parts by weight of zinc flakes, 10 to 15 parts by weight of a plasticizer, 5 to 10 parts by weight of a nucleating agent, and 0 to 5 parts by weight of a solvent. By applying the coating composition, the coating layer is formed, thereby obtaining properties preventing slipping and static electricity.

The above acrylic resin is widely used as a resin component when forming a coating layer because it has excellent durability and impact resistance. In particular, it is preferable to use one having a weight average molecular weight of 10,000 to 50,000, which can be selected in consideration of compatibility with other components constituting the composition.

The above butadiene rubber exhibits properties of both plastic and rubber and has excellent compatibility with acrylic resin, so it exhibits performance of reducing slippage when included in the composition. The SBS exhibits anti-slip properties when included in a range of 30 to 40 parts by weight. However, if the SBS content is too low, the anti-slip properties of the coating layer are insufficient, and if it is too high, the coating performance of the coating composition deteriorates, resulting in a decrease in the durability of the coating layer.

In addition, the acrylic acid is used as a crosslinking monomer to increase the crosslinking degree of the resin and improve surface hardness and adhesion. If the content of the acrylic acid is too low, curing may not proceed sufficiently and surface hardness may decrease, and if it is too high, cracks in the coating layer may occur or adhesion may decrease.

In addition, the silicate may be contained for dispersing the rust inhibitor. As the silicate, sodium silicate, potassium silicate or colloidal silica may be used. If the content of the silicate is too small, the dispersibility of the rust inhibitor is reduced, thereby reducing the rust inhibitor effect, and if the content is too large, the adhesion of the coating layer may be reduced.

In addition, the aluminum flakes and zinc flakes have a faster corrosion rate than iron and act as a rust inhibitor that prevents corrosion of the substrate. The flakes are plate-shaped particles, and it is preferable to classify them into particle sizes of 150 mesh or more in consideration of dispersion within the composition. The aluminum flakes and zinc flakes are preferably contained in a weight ratio of 2:1 to 1:1, and it was found that rust prevention and adhesion may be reduced when the weight ratio is exceeded.

In addition, the plasticizer is a component added to improve the processability of the composition mixed with PP and SBS. Generally, a phthalate plasticizer is used, but in the present invention, dioctyl terephthalate (DOTP), which is a non-phthalate plasticizer, can be used. The plasticizer is used in the range of 10 to 15 parts by weight. If the content of the plasticizer is too little or too much, the processability of the coating composition may be insufficient and the durability of the coating film when coated on the surface may be reduced, so it is preferable to use it in the above range.

In addition, the nucleating agent is used to obtain the function of shortening the curing time in the coating composition in which different resins are mixed. Generally, components such as silica, aluminum hydroxide, talc, and kaolin are used as the nucleating agent, and in the present invention, silica having an average particle size of 1 to 30 μm is used. It was shown that the use of the silica increases the compatibility of the resin contained in the coating composition of the present invention, thereby shortening the curing time, and further, it was shown that it is preferable to use silica having an average particle size of 1 to 30 μm in order to improve the dispersibility. It was shown that when the particle size is too small, the process efficiency is lowered, and the dispersion degree or dispersion deviation is lowered, and when it is too large, the dispersion degree of the nucleating agent is lowered, which reduces the effect of shortening the curing time, and thus, a defect in the coating film occurs when forming the coating layer.

In addition, any one alcohol among methanol, ethanol, propanol, and isopropanol can be used as the solvent. The solvent does not have to be used, but if it is used in excess of 5 parts by weight, the mechanical properties of the coating layer may deteriorate, so it should be used in an appropriate amount as needed.

In addition, in addition to the above components, a small amount of additives may be added. Such additives may include coupling agents, antioxidants, UV stabilizers, flame retardants, pigments, heat stabilizers, dispersants, etc., and may be contained in the range of 1 to 5 parts by weight per 100 parts by weight of PP.

In describing the present invention above, the "folding pallet for export" having a specific shape and structure has been mainly described with reference to the attached drawings, but the present invention can be variously modified and changed by those skilled in the art, and such modifications and changes should be interpreted as falling within the scope of protection of the present invention.
