Description

Post Pallet {POST PALLET}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a post pallet having posts on the corners of pallets, and more particularly to a post pallet that can be easily loaded and unloaded on pallets and compacted when not in use.

In recent years, with the development of domestic and overseas distribution, for example, in the conveyance of cargo, such as a glass substrate, the post pallet which has a post standing upright on the four corners of a pallet is used. As such a post pallet, what is disclosed by Unexamined-Japanese-Patent No. 09-216630 is mentioned, for example.

The outline of an example of the conventional post-palette is shown in FIG.

The steel post pallet 101 has a structure in which four posts 103 are respectively erected in four corners of a rectangular pallet 102 for loading a cargo to be conveyed as a whole.

Of these four posts, three other than one side (here, right post 103FR) on the front side of the post pallet 101 are connected to the adjacent post and the auxiliary member 109.

In addition, side boards 105 are provided on the left and right side surfaces of the post pallet 101. Each side of each post 103 is provided with two sets of board-like plate-like members 105 'and sideboards 105 are inserted between two plate-like members 105' and fixed between the posts. .

In addition, on the rear side (back side) of the post-palette 101, it has a backrest 106 for connecting the auxiliary member 109 and the pallet 102 and supporting the back side of the cargo. ) Is provided with a cushioning material (polyethylene foam).

Moreover, the pallet 102 is equipped with the cushioning material in the surface of the pallet 102, and the rubber sheet for slipping is provided on the surface of the pallet 102 in order to prevent cargo from slipping in the location where cargo is loaded.

And the said post 103FR is separable into two (post part 103FRa, leg part 103FRb) as shown in explanatory drawing of FIG. 18, and the post part 103FRa is a cylindrical leg part 103FRb. It is removable by inserting inward. When loading and unloading cargo on the pallet 102, the post part 103FRa is pulled out and a removal operation is performed, and it becomes possible to prevent the post part 103FRa from being disturbed.

Meanwhile, the remaining three posts 103 are welded to the pallet 102 or the auxiliary member 109 and fixed to each other inseparably.

In addition, the cargo is packaged with vinyl or the like and bundled with a PP band or the like, and then loaded onto the post pallet 101 to be tied back to the PP band for each post pallet 101 to be fixed.

Conventionally, the cargo was conveyed domestically or abroad using such a post pallet 101. In particular, in the case of returning overseas, postal pallets that have been returned together with the cargo are expensive even if they are returned to the destination. Therefore, postal pallets sent overseas are generally sent abroad instead of being returned. That is, it has been used as a one-way pallet.

However, if the post-palette is not collected at the conveying destination in this way, it is a disposable one, so that costs are high. In addition, in recent years, cost competition has been intensifying in the distribution industry, and in such a aspect, there is a demand for reduction of the cost required for the conveyance of cargo.

In addition, as shown in Figs. 17 and 18, there are detachable parts such as posts 103FRa and side boards 105 of the posts. However, since such a structure is used, there is a problem of missing parts. In addition, the assembly needed to find these parts first, which required time for work.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and by increasing the amount that can be transported in one compact form, it is possible to reduce the cost required for returning to the destination, etc. As a result, it is possible to reduce the cost required for relinquishing the pallet and the entire conveyance. It is an object of the present invention to provide a post pallet that can be easily and easily assembled and that can easily carry in and out of cargo.

In order to solve the above problems, the present invention provides a post pallet for loading cargo, at least a rectangular pallet, a post standing upright on each of the four corners of the pallet, and at least an upper end portion surrounding and supporting the post. Corner posts of the four posts and the corner posts, among the two provided on the front side of the post-palette for taking out and out of the c-shaped corner posts, the openings of which face toward the inside, respectively, The posts can be folded freely inward to each other on the pallet, and at the same time, one of the corner pillars has a foldable portion that can be folded outward of the pallet. Each opening faces forward and the posts are both placed on the pallet. Provided is a post pallet, which can be freely folded forward.

As described above, in the post pallet of the present invention, first, posts erected on rectangular pallets and their corners, and at least upper end portions surrounding and supporting the posts are provided with c-shaped corner pillars. In the two posts and the corner posts, the corner posts each have an opening facing inward and the posts are free to fold inward to each other on a pallet. In addition, in the two posts and the corner posts on the rear side, the corner posts have their openings facing forward, respectively, so that the posts can be freely folded forward on both pallets.

That is, the posts standing upright on the four corners of the pallet can each be folded onto the pallet, and can be folded and compacted if the cargo is not loaded, for example, simply returning the post pallet itself to the destination of the cargo. It is possible to increase the amount to be loaded at one time in a container or the like. Therefore, unlike the conventional products in which the shape is fixed even when the cargo is not loaded and the loading amount into the container cannot be increased, the cost due to return to the destination can be significantly reduced. As a result, in terms of cost, it is not a one-way pallet that the return destination only sends overseas, but a literal pallet that can be returned and used again. This makes it possible to reuse one of the solutions to the recent environmental problems.

In addition, since any corner post on the front side of the post pallet has a foldable portion that can be folded outside of the pallet, folding the post onto the pallet and folding the fold outward of the pallet prevents the folding of the corner post. Instead, the shipment of the cargo onto the pallet becomes very easy and the work efficiency is significantly increased.

Moreover, unlike the prior art which has the post part 103FRa (refer FIG. 18) of the post to separate, in this invention, since all the posts can be folded freely and a folding part can be folded, for example, a pallet is stored. Even if it is removed when it is loaded on the floor, it is not easy to lose the post that has been separated thereafter.

At this time, the post is formed with a long hole on the side, by the post rotation shaft rod penetrating the long hole in the side of the corner pillar, the post is pivotally connected to the corner pillar to enable the vertical movement, the The post fixed by inserting in a corner post can be made to be rotatable on the said pallet by pulling out to the c-shaped part of a corner post.

Thus, for example, a long hole is formed on the side of the post, and the post is pivotably connected to the corner post by a post pivot shaft that penetrates into the long hole of the post. By inserting the corner posts into the corner posts, the fixed posts can be pulled up to the corners of the corner posts so that they can be rotated onto the pallet, thereby more reliably integrating the posts and the corner posts so that the posts are not separated and lost. In addition, the post can be fixed upright by a corner post while being pulled out and folded on a pallet.

The folding part of the edge pillar provided in the front side of the said post-pallet can be connected by engaging with the lower fixed leg part by the hinge.

In this way, if the folds of the corner posts provided on the front side of the post-pallet are connected to the lower fixed legs by hinges, the folds can be folded outside the pallet without removing the folds, thereby preventing the cargo from being unloaded. It doesn't work.

In addition, it is preferable that the corner pillar provided on the front side of the post pallet and provided with a folding portion further includes a locking mechanism for fixing when the folding portion and the leg portion are engaged.

Thus, when the folding part and the said leg part are provided with the locking mechanism to fix, the folding part was not intended, but it is not folded, and it can be more reliably engaged and fixed to the leg part.

The post pallet further includes sideboard mechanisms for supporting the cargo via the left and right sides, each sideboard mechanism having at least a sideboard for supporting the cargo and a pallet formed on the pallet in the transverse direction of the post pallet. And a rail holder surrounding the rail and an arm connecting the rail holder and the sideboard, wherein the rail holder is slidable along the rail and connected to the rail holder through the arm. The sideboard is slidable along the rail, the rail is formed with a rail hole, and the sideboard has a sideboard fixing pin for fixing the position of the sideboard, the sideboard fixing pin The position of the sideboard may be fixed by being inserted into the rail hole.

Thus, it is preferable to further have the sideboard mechanism to support the cargo via the left and right side, since the cargo can be transported more stably. In the case of each sideboard mechanism as described above, the sideboard supporting the cargo is connected to the rail holder and the arm that can slide along the transversely extending rail of the post pallet, so that the sideboard can slide along the rail. . Furthermore, each rail has a rail hole, and the sideboard has sideboard fixing pins for fixing the position of the sideboard, and the sideboard fixing pins are inserted into the rail holes to fix the position of the sideboard. Since the sideboard fixing pins are pulled out or inserted in accordance with the width of the cargo, for example, the sideboard can be slid and adjusted at the same time. The cargo can be secured in the horizontal direction. It can be stabilized.

At this time, the rail holder and the arm are connected via a sideboard pivot shaft, the arm and the sideboard connected to the sideboard pivot shaft to be integral with the pivot to the inside of the post pallet. Is preferably.

In such a case, since the arm and the sideboard are integral with the sideboard pivoting shaft as the axis and can be rotated toward the inside of the post pallet, even if the sideboard mechanism is provided, the arm and the sideboard can be folded by rotating on the pallet. It becomes possible to become more compact when there is no freight.

In the left and right sideboard mechanisms, the length of the arm can be varied from left to right.

In this way, if the length of the arm is different from the left and right sideboard mechanisms, for example, left and right, the sideboard can be sufficiently separated from the pallet, so that the sideboard can be sufficiently separated from the pallet. You can prevent it from getting in the way.

In addition, the pallet, the post, the corner pillar, the sideboard mechanism is preferably integrated.

In this way, if the pallet, the post, the corner post, and the sideboard mechanism are integrated, these parts are not separated and the loss of the parts can be prevented. Since it is integrated, finding a separated part as in the prior art can be omitted, and the assembly work of the part can be performed efficiently.

It is preferable that the fork guide is installed on the pallet.

In this way, if the fork guide is installed on the pallet, it is possible to easily and stably move the post pallet or post pallet itself loaded with cargo using a fork lift.

Further, the pallet has a cushioning material for loading cargo, and the cushioning material is preferably located higher than two posts on the front side of the post pallet folded inwardly on each other on the pallet.

Thus, if the pallet has a cushioning material for loading cargo, and the cushioning material is positioned higher than the two posts on the front side of the post pallet folded inward to each other on the pallet, the posts are not disturbed even when the two front sides are folded. It is possible to take in and out of cargo without having to.

The post pallet of the present invention can be made compact, so that the cost of refilling the pallet and the overall conveyance can be reduced. In addition, the assembly is simple, and the loading and unloading of the cargo can be facilitated.

EMBODIMENT OF THE INVENTION Hereinafter, although embodiment of this invention is described with reference to drawings, this invention is not limited to this. In addition, here, the post pallet which is especially suitable in the case of carrying out a cargo from the front side of a post pallet and a right side is demonstrated. However, it is also possible to respond to the case where the cargo is withdrawn from the left side, and in this case, the left and right sides may be reversed.

The outline of an example of the whole post-palette of this invention is shown in FIG.

The post-pallet 1 of the present invention has a rectangular pallet 2 on which cargo is loaded and supports the bottom of the cargo, and posts 3 are erected upright at the corners thereof, and the post 3 is also provided. It has a corner post 4 that surrounds and supports it.

In addition, the left and right sides of the post pallet 1 are provided with sideboard mechanisms 5 and 5 'for supporting the cargo so as to be interposed from the left and right side sides. In addition, in FIG. 1, only the left sideboard mechanism 5 (the right side is 5 ') is shown. In reality, the same mechanism is provided on the right side as opposed to the one on the left side.

In addition, the material of this post-palette 1 is not specifically limited, What is necessary is just to have a strength etc. which can support a cargo stably, and it can determine suitably according to the kind, weight, etc. of the cargo to load. Although the material may be made of wood or the like, for example, if the steel is made of steel, it is a material that has sufficient strength and is frequently used in the past, and is preferable because each component in the present invention can be produced more simply. Here, the description will be made of steel.

Hereinafter, each said component is demonstrated more concretely.

First, the pallet 2 is a grid | lattice form as shown in FIG. 1 by welding etc. using the rod-shaped member.

In the vicinity of the center of the lattice pallet 2, the front side and the rear side (back side) of the post pallet 1 are connected (that is, in the front-back direction), and two rod-shaped members are provided. The shock absorbing material 7 is attached. The cargo can be loaded in the place where this buffer material 7 is attached, and it can support without damaging a cargo. As this cushioning material, foam of polyethylene can be used, for example. Moreover, you may adhere | attach a rubber sheet etc. on it as a slip prevention of a cargo. The shock absorbing material 7 and the anti-slip material can be the same as in the prior art.

In addition, the fork guide 10 is provided in the pallet 2, and the fork lift forklift is put in this fork guide 10, and the pallet 2 can be lifted and conveyed. The position, number, etc. of the port guide 10 can be suitably determined, and may be provided according to the fork guide etc. to be used.

In addition, in the pallet 2, the location which attaches the said buffer material 7 to the surface, the number of the rod-shaped members which comprise, etc. are not specifically limited, It can determine suitably according to the size, shape, weight, etc. of the cargo to load.

In addition, the pallet 2 should just be able to support cargo, and is not limited to the lattice shape like FIG. For example, a planar thing can also be used. It may be appropriate in consideration of manufacturing cost, weight, strength, and whether or not it is easy to convey.

This pallet 2 can be made into the structure similar to the former except the location of the rail 25 of the sideboard mechanism 5 demonstrated later.

Next, the post 3 and the edge pillar 4 are demonstrated.

First, the main features common to all the posts 3 and the corner posts 4 will be described with reference to FIGS. 2 and 3. The outline of the post 3 was shown in FIG. 2, and the outline of the edge pillar 4 was shown in FIG.

The post 3 is, for example, in the shape of a square, and a long hole 3 is formed along the longitudinal direction of the post 3 on the side. The post 3 is fixedly supported in an upright position by standing up by the corner post 4 and can be folded onto the pallet 2. Although the shape of the post 3 is not specifically limited, It is easy to be stabilized when folded when it is a columnar shape.

In addition, the four corner posts 4 have a c-shaped shape (c-shape) 11 at the upper end thereof, whereby the posts 3 toward the opening 15 of the c-shaped when the upright posts 3 are pulled out of the corner posts. ) Can be folded.

Moreover, the lower part of the edge pillar 4 is hollow as the cylindrical part 12, and can insert the lower end part of the post 3 in this hollow part, and it stably stably in the state which made the post 3 stand up. It can be fixed and supported. Moreover, the lower part of the edge pillar 4 is connected with the pallet 2. In the case of the post-pallet 1 of FIG. 1 each made of steel, the edge pillars 4 and the pallet 2 are welded and fixed.

In addition, although the lower end part of the edge pillar 4 is a pedestal shape so that the post pallet 1 may be stabilized, what is necessary is just a shape which can stabilize the post pallet 1.

And the post-spinning shaft bar 14 which penetrates into the elongate hole 13 of the said post 3 in the edge post 4 is inserted in the edge post 4. In addition, since the post 3 and the corner post 4 are shown separately in FIGS. 2 and 3, the long hole 13 of the post 3 and the shaft for the post rotation 14 of the corner post 4 are engaged. In reality, as shown in Figs. 4 and 5, they are engaged with each other and are integrated.

Here, the relationship between the vertical movement and rotation in the post 3 and the edge pillar 4 is demonstrated more concretely.

In FIG. 4, the lower end part of the post 3 was inserted in the hollow part of the cylindrical part 12 of the edge pillar 4, and was shown to stand up and fixed. 5, the lower end part of the post 3 showed the state by which the c-shaped part 11 was pulled and rotated from the hollow part of the cylindrical part 12 of the edge pillar 4. As shown in FIG.

In the case where the post 3 is upright, as shown in FIG. 4, the post 3 is inserted into the hollow part of the corner pillar 4, At this time, the post rotation shaft bar 14 of the corner pillar 4 is a post. It is located above (or the upper end) of the long hole 13 of (3).

On the other hand, when folding the post 3, as shown in FIG. 5, the post 3 is first pulled from the hollow part of the edge pillar 4 to the c-shaped part 11, and thereby the long hole of the post 3 is made. The post 3 is rotated using the axis | shaft 14 for post rotation of the edge pillar 4 which moved relatively to the lower end of 13 as an axis. With this structure, the post 3 can be rotated in the direction of the opening portion 15 of the c-shaped portion 11 of the corner post 4 without being separated from the pallet 2. In addition, the long hole 13 may have a shape as shown in Fig. 2, for example, as shown in Figs. If it is such an L-shape, it is possible to prevent the post 3 from interfering with the inner surface of the corner post 4 when driving the post 3.

In this way, the posts 3 and the corner posts 4 located at the four corners of the pallet 2 have the same characteristics as described above. Fig. 6A is a front view of the post pallet 1 viewed from the front side. However, only the post 3 (left side 3FL, right side 3FR), the corner post 4 (left side 4FL, right side 4FR) and the pallet 2 of the front side were shown for clarity.

As shown in FIG. 6 (A), in the two corner posts 4FL and 4FR located on the front side of the post-palette 1, the openings 15 face inward. For this reason, when each post 3FL, 3FR is folded, it can turn to the opening 15 direction, ie, all toward the inside of the post pallet 1, and can be folded on the pallet 2.

Further, in the two corner posts 4RL and 4RR on the rear side, the openings 15 face the front of the post pallet 1 respectively, and each of the posts 3RL and 3RR both rotate forward and the pallet 2 ) Can be folded onto. Fig. 6B shows the driving state of the post 3RR on the right side of the rear side, but the post 3RL on the left side of the rear side can be similarly driven.

In addition, as shown in Figs. 1 and 6, the two posts 3RL and 3RR on the rear side are connected by two auxiliary members 9, and the two auxiliary members 9 are connected to each other so that the rear side of the cargo is connected. Two plate-shaped backrests 6 for supporting are provided with the cushioning material 7 on the surface. The backrest 6 is provided inclined 5 degrees in the vertical direction (in the posts 3RL and 3RR), for example, when the post 3 is upright and fixed. With such a tilt, cargoes such as glass substrates can be tilted to the backrest 2 to be supported. Of course, the number and shape of these auxiliary members 9 and the backrest 6, the inclination degree of the backrest 6, etc. are not specifically limited.

In addition, for each of these backrests 6 and the like, two posts 3RL and 3RR on the rear side can be folded together in a square.

In addition, although the height position of the post rotation shaft bar 14 of the edge pillar 4 used as the axis | shaft which the post 3 rotates is not specifically limited, For example, in the front side, as shown to FIG. It can install so that the height position of the post rotation shaft bar 14 in the right corner pillar 4FL may become higher than the height position of the post rotation shaft bar 14 in the corner pillar 4FR on the right side. If it is such a thing, since each post 3FL, 3FR is folded in parallel and can be folded more compactly when folded, it is preferable.

In addition, the long hole 13 of the post 3 is also formed at the rear side by bending the letter “A”, and when the post 3 is folded in front of the post 3 and also assembled in reverse, the post 3 is the inner surface of the corner post 4. Interference can be prevented.

In the post-pallet 1 of the present invention, the corner post 4FR on the right side of the front side (in this case, corresponds to the side where the cargo is taken in and out) is the folding portion 16 and the leg portion 17 as shown in FIG. They are connected by hinges 18. As shown in the structural explanatory drawing of the corner post 4FR of FIG. 7 (when seen from the front side of the post pallet 1), there is a leg 17 under the corner post 4FR, and the pallet 2 and It is connected (welded) and fixed. In addition, there is a folding portion 16 above the corner post 4FR, and is connected through the hinge 18 to engage with the leg portion 17. The post 3FR is rotated inward and folded onto the pallet 2 as described above. On the contrary, the folding part 16 is configured to be folded toward the outside of the pallet.

In this way, since the post 3 can be folded inward and the folding portion 16 of the corner post 4 can be folded outward, the post 3FR when the cargo is withdrawn from the corner post 4FR portion. ) And corner pillars 4FR (folding portion 16) can be worked without interference.

In addition, by using such a structure, it becomes possible to prevent the post pallet having a wider width than necessary to secure workability. That is, the size of a post pallet can be made as small as possible, and since a more compact post pallet can be used even when cargo of the same size is loaded, the number of loading to a container etc. can be increased further.

However, when the posts 3FL and 3FR on the front side are folded and folded as shown in Fig. 6A, when the cushioning material 7 provided on the pallet 2 is located higher than these posts 3FL and 3FR, both It is preferable because the posts can be withdrawn from the cargo on the cushioning material 7 without being obstructed. 6C shows an example of the positional relationship between the posts and the buffer material in the case where the shock absorbing material 7 is provided at a position higher than the posts 3FL and 3FR.

In addition, when the posts 3FR are held upright and fixed, such as loading cargo and transporting the post pallets 1, the posts 16FR are supported without being folded at the corner posts 4FR. It is preferable to provide the lock mechanism 19 in the corner pillar 4 so that the folding part 16 and the leg part 17 may be fixed so that it may be fixed. 8 shows a state in which the folding portion 16 and the leg portion 17 engaged by the locking mechanism 19 are locked. 8 shows the case seen from the front side of the post pallet 1.

This lock mechanism 19 should just be able to fix the folding part 16 and the leg part 17 which were engaged, and is not specifically limited. For example, a pair of cylindrical locks are formed such that the positions of the inner cavity coincide with the sides of the folding portion 16 and the leg 17 when the folding portion 16 and the leg portion 17 are engaged. It can be set as the structure which is equipped with the dragon member 20, and inserts the pin 21 in the cavity inside this cylindrical member 20 from upper direction. Such a structure can be simply locked, and also simple because only the pin 21 needs to be removed when the lock is released. For example, if only the head of the pin 21 is larger than the diameter of the cavity, the head of the pin 21 can be reliably locked without being caught by the upper end of the cylindrical member 20.

In addition, a lock mechanism can be provided also in the posts 3RL and 3RR on the rear side.

An example of this lock mechanism is shown in FIG. It is the figure seen from the front side of the post-palette 1, and the post 3RL of the left side is taken as an example. An insertion opening 23 is formed on the side of the corner post 4RL so as to slide the pin 22 in the horizontal direction so that the insertion slot 23 can be inserted. When the post 3RL is upright and fixed to the corner post 4RL, the insertion opening The pin 22 is inserted into the 23 and the pin 22 can be locked by inserting the pin 22 into a hole provided at a corresponding position of the post 3RL.

Next, the sideboard mechanisms 5 and 5 'will be described.

The left and right sideboard mechanisms 5 and 5 '(5 on the left and 5' on the right) are mainly in the transverse direction as shown in the plan view of Fig. 1 and Fig. 11 showing the outline of the sideboard mechanism. The side board 24 supporting, the rail 2 formed in the pallet 2, the rail 25 extending in the lateral direction of the post-pallet 1, and the rail 25 are arranged so as to be slideable along the rail 25. The rail holder 26 and the arm 27 which connects the rail holder 26 and the said side board 24 are comprised.

The side board 24 has a cushioning material 7 attached to the surface of the cargo side, and can be supported from the side without damaging the cargo. Here, FIG. 10 shows the relationship between the sideboard and the rail when the sideboard 24 is seen from the back side. In the center of the lower surface side of the back board side of the side board 24, the pin (side board fixing pin 28) which can be taken in and out by a spring apparatus is provided.

The rail 25 is formed with a rail hole 29 having a size capable of inserting at least the sideboard pin 28. The number of the rail holes 29 is not particularly limited, and a plurality of rail holes 29 can be provided along the rail 25.

12, the cross section of the rail 25, the rail holder 26, and the arm 27 at the time of the arrow A of FIG. 11 is shown. The rail holder 26 is formed in a cylindrical shape to surround the rail 25, and may slide along the rail 25. The hook-shaped end portion 26 'extending from the cylindrical portion of the rail holder 26 to both sides is connected to the arm 27 via the sideboard pivot shaft 30.

The other side of the arm 27 is connected to the side board 24 (welded), and the side board and the arm 27 are integrated.

With the above structure, when the rail holder 26 slides along the rail 25, the arm 27 connected with the rail holder and the side board 24 connected to the arm 27 are connected. In the same way it can be sliced along the rail 25.

In addition, the sideboard 24 can be fixed at a desired position by inserting the sideboard fixing pin 28 provided in the sideboard 24 into the appropriate rail hole 29. This fixing position can be suitably determined according to the width | variety of the width | variety, etc. of the cargo to load on the pallet 2. As shown in FIG. When the fixing position is changed, the sideboard fixing pin 28 can be removed by sliding it once from the rail hole 29 to adjust the position, and then simply inserting it into another rail hole 29.

In addition, since the rail holder 26 and the arm 27 are connected by the sideboard rotation pin 30 as shown in FIG. 12, the arm 27 is made into the axis | shaft with the sideboard rotation pin 30 as an axis. ) Can be rotated by performing the inside of the post pallet 1. At this time, as described above, since the sideboard 24 is connected to the arm 27, the sideboard 24 is driven integrally with the arm 27. By driving the arm 27 and the sideboard 24 in this manner, the sideboard mechanisms 5 and 5 'can be folded onto the pallet 2 and can be made more compact when not in use. The state at the time of folding the sideboard mechanism 5 'of the right side in FIG. 13 was shown. 13 has shown the case seen from the front side of the post-palette 1.

Since the arm 27 connected to the side board 24 is connected to the rail holder 26 and the side board pivoting shaft 30, the side board pivoting shaft 30 and the side The board 24 is connected at a spaced apart position by the arm 27 and can prevent the sideboard 24 from simply folding inward during operation.

In addition, the lengths of the arms 27 in the left and right sideboard mechanisms 5 and 5 'may be different from each other. In such a structure, that is, for example, when the arm 27 of the right sideboard mechanism 5 'is made longer, the sideboard 24 is further positioned from the pallet 2 in the right direction (the pallet of Outside), the sideboard 24 can be carried out more easily and safely without disturbing the sideboard 24, so that the work can be effectively performed.

In addition, the left and right sideboard mechanisms 5 and 5 'may be interlocked with each other, and the sideboard 24 may be slid along the rail 25, for example.

The shape difference and interlocking property in these left and right sideboard mechanisms 5 and 5 'can be appropriately determined in consideration of work efficiency, costs required for manufacturing, the kind of cargo to be loaded, and the like.

Moreover, it is preferable that the pallet 2 mentioned above, the post 3, the edge pillar 4, and the sideboard mechanisms 5 and 5 'are integrated. In particular, in the conventional products, the post 3 and the sideboard 24 of the sideboard mechanism are detachable and may be lost when separated. However, in the present invention, since they are integrated, the parts are not basically separated. Therefore, the loss of parts can be effectively prevented.

Hereinafter, the procedure to load a cargo in the post pallet 1 of this invention is demonstrated. The cargo to be loaded on the post-pallet 1 is not particularly limited. For example, a case in which a plurality of glass substrates are collected and loaded into blocks is described as an example.

First, the glass substrate, which is a cargo, is piled up with a polyethylene sheet interposed between the substrates and a little larger than the glass substrate, and the entire glass substrate is wrapped with a vinyl sheet again. After that, it is made into a block shape by tying in a PP band.

On the other hand, in the post pallet 1, the front right side post 3FR is first folded inward, and the folding portion 16 of the corner post 4FR is folded outward of the pallet 2. The other post 3 may be fixed in an upright state. In the right sideboard mechanism 5 ′, the sideboard 24 is spaced apart from the pallet 2 by sliding the rail holder 26 to the far right of the movable range of the rail 25.

In this manner, after the cargo is easily prepared for taking in and out of the cargo, the cargo is actually loaded onto the pallet 2. For example, it can be loaded using a human hand or a forklift. And the cargo is supported by the back side leaning to the backrest 6, and the side surface of right and left is supported by interposing from side to side using side board mechanisms 5 and 5 '. At this time, the sideboard fixing pin 28 is inserted into the rail hole 29 to fix the position of the sideboard 24 to an appropriate position.

In addition, the folding portion 16 of the right corner pillar 4FR on the front side, which is folded for the first time, is raised and engaged with the leg portion 17, and then the connecting portion is fixed with the lock mechanism 19. In addition, the post 3FR is erected and fixed by inserting the lower end into the corner post 4FR to stand up.

Then, the loaded cargo is bundled and further stabilized by the post pallet (1) using a PP band or the like, and then the fork lift is inserted into the fork guide 10 to convey the cargo per post pallet (1) using the forklift. .

On the other hand, when cargo is not loaded, such as when returning it to a return destination, it is folded and made compact. For example, first, the sideboard mechanisms 5 and 5 'are folded onto the pallet 2 by driving the sideboard 24 and the arm 27 inward. Then, the front posts 3FL and 3FR are pulled up to the c-shaped portions 11 of the corner posts 4FL and 4FR, and folded inwards alternately, and the rear posts 3 are also rotated forward in the same manner so that the sideboard mechanism It can be folded to cover over (5, 5 ').

If it is in this state, the height of the post-pallet 1 can be made into half or less, for example, and the quantity to load in a container at once can be remarkably increased. Thereby, the cost of returning can be reduced, and especially when carrying a cargo overseas, it becomes possible to use it as a literable pallet returning to a conveying destination instead of a one-way pallet in terms of cost (refer FIG. 14).

Although an Example of this invention is given to the following and it demonstrates this invention in detail, this does not limit this invention.

(Example)

When returning to the conveyance destination about the steel plate of this invention made from steel as shown in FIG. 1, the number which can be loaded to a container was examined.

In addition, the container which loads a post pallet at the time of return was made into the high cube standard [12000 mm (length) x 2340 mm (width) x 2585 mm (height)) by 40 feet in length.

Post pallets were prepared for the transport of 50-inch (116 cm) glass substrates. In this post pallet, when the cargo is loaded, that is, when all the parts such as posts, corner posts and sideboard mechanisms are assembled upright, the size is 750 mm (depth) x 1310 mm (width) x 950 mm (height).

On the other hand, the size in the case where the post, sideboard mechanism, etc. were rotated inside the post-pallet and folded into a compact form, was 75 mm (depth) x 1310 mm (width) x 415 mm (height). In other words, it was found that the height of the post-pallet can be reduced to about 44% (415 mm / 950 mm) when folded compared to when loading cargo.

Thereby, when loading cargo per container in terms of volume, as shown in the top view when loading the post-palette of FIG. 15, it is 27 pieces per stage, and the total number is 54 (3 units x 9 rows x 2 stages). However, when folded for return, 162 units (3 units × 9 rows × 6 stages) of post pallets can be loaded into the container (the number of units per stage when loaded is the same as above, but the number of stackable units is different) . In addition, an example of the state which mounted the post-palette 1 was shown in FIG. The upper end of the corner post of the lower post pallet can be stably loaded by inserting the leg of the lower end of the corner post of the upper post pallet.

In this way, the number of post pallets per container to be loaded can be remarkably improved (3 times in this case) when the cargo is returned than when the cargo is loaded and returned, and the post pallet can be returned to the destination with good efficiency. Do.

(Comparative Example)

When returning the conventional post pallet to the conveyance destination, the number which can be loaded in a container was examined similarly to an Example.

The size of this conventional post pallet is 750 mm (depth) x 1350 mm (width) x 1000 mm (height). It is slightly larger in size than the present invention in order to secure a space for taking in and out of cargo. In the prior art, since one post can be separated as shown in Fig. 18, but another post cannot be folded, the entire size can be changed even when the cargo is not loaded, such as when loading or returning the cargo. Can't.

Therefore, in the conventional products, even at the time of returning, as shown in the top view of FIG.

In addition, even if the size of the post pallet is 750 mm (depth) x 1310 mm (width) x 950 mm (height) as in the case of loading the cargo of the embodiment, the size cannot be reduced at the time of return. (3 units x 9 rows x 2 steps) can only be loaded.

As described above, in the conventional products, as shown in the comparative examples, most of the posts are welded to pallets and cannot be folded. For example, the posts cannot be made smaller in size with respect to the size at the time of loading the cargo even when it is to be returned to the destination. Therefore, the return efficiency is poor, and in terms of cost, it cannot be used as a literable pallet, and it is inevitably a one-way pallet.

However, in the case of the post pallet of the present invention, since the post pallet can be folded and compacted at the time of return as shown in the embodiment, it is possible to increase the number of possible volumes per container in terms of volume. Thereby, the cost at the time of return can be reduced, and even if it is used by a literable pallet, a profit can fully be raised.

In addition, this invention is not limited to the said embodiment. The above embodiments are exemplary and all of them having substantially the same constitution as the technical idea described in the claims of the present invention and having the same working effects are included in the technical scope of the present invention.
