Description

  The present invention relates to a post pallet having posts at four corners of the pallet, and more particularly to a post pallet that allows easy loading and unloading of a load on the pallet and can be made compact when not in use.

  With the development of domestic and overseas distribution in recent years, for example, so-called post pallets, which are provided with upright posts at the four corners of the pallet, have been frequently used for transporting packages such as glass substrates. Examples of such a post pallet include those disclosed in Patent Document 1.

FIG. 17 shows an outline of an example of a conventional post pallet.
The steel post pallet 101 as a whole has a structure in which four posts 103 stand upright at the four corners of a rectangular pallet 102 on which a load to be transported is placed.
Of the four posts, three other than the one on the front side of the post pallet 101 (here, the right hand post 103FR) are connected to the adjacent post by an auxiliary member 109.
Further, side boards 105 are provided on the left and right side surfaces of the post pallet 101. On each side of each post 103, a pair of plate-like members 105 ′ for inserting a board is provided, and the side board 105 is inserted between the two plate-like members 105 ′ and between the posts. Fixed to.

Further, on the rear side (back side) of the post pallet 101, there is a backrest 106 for connecting the auxiliary member 109 and the pallet 102 and supporting the back side of the load, and a cushioning material is provided on the surface of the backrest 106. (Polyethylene foam) is provided.
Further, the pallet 102 is provided with a cushioning material on the surface of the pallet 102 and a rubber sheet for preventing the slip is provided on the surface of the pallet 102 in order to prevent the luggage from slipping at a place where the load is placed. It has been.

The post 103FR is separable into two parts (post part 103FRa and leg part 103FRb) as shown in the explanatory view of FIG. 18, and the post part 103FRa is placed inside the cylindrical leg part 103FRb. It can be removed by inserting and removing. When loading / unloading the cargo onto / from the pallet 102, the post portion 103FRa is pulled out and removed to prevent the post portion 103FRa from becoming an obstacle.
On the other hand, the remaining three posts 103 are welded to the pallet 102 and the auxiliary member 109 and cannot be removed and are fixed to each other.
Further, the package is wrapped with vinyl or the like, bound with a PP band or the like, and then placed on the post pallet 101, and the post pallet 101 is further bound and fixed with the PP band.

  Conventionally, such post pallets 101 have been used to transport packages to the country and abroad. And in particular, when transporting overseas, it is costly to return the post pallet transported with the package from the transport destination, so generally the post pallet sent overseas is not returned, It has been used overseas as a so-called one-way pallet.

However, if the post pallet is not collected from the transport destination in this way, the post pallet is disposable, and thus costs are increased accordingly. Further, in recent years, cost competition has increased in the distribution industry, and from this aspect, it is desired to reduce the cost required for transporting packages.
Moreover, as shown in FIGS. 17 and 18, there are separable parts such as the post part 103 FRa of the post and the side board 105, but the problem is that the parts are lost because of such a structure. It was. Also, for assembly, it is necessary to search for these parts first, and work takes time.

JP 09-216630 A

  The present invention has been made in view of such a problem, and by reducing the cost required for returning from the transport destination by reducing the size and increasing the transport amount possible at one time, the pallet It is an object of the present invention to provide a post pallet that can be made returnable and can reduce the cost required for the entire conveyance, can be easily assembled, and can be easily carried in and out.

  In order to solve the above-mentioned problems, the present invention provides a post pallet for carrying a load, and at least a rectangular pallet and four posts of the pallet, respectively, standing upright and surrounding the post. At least the upper end portion to support is provided with a U-shaped corner post, and among the four posts and the corner post, two of the four posts and the front post provided on the front side of the post pallet for taking in and out the load, The corners of the mold are opposed to each other with the openings facing inward, and the posts can be folded inward on the pallet, and either one of the corner pillars can be moved to the outside of the pallet. In the two posts and corner pillars on the rear side, each of the U-shaped corner pillars has an opening facing forward, and the posts are arranged on the pallet. Both up front Providing a post pallet, characterized in that the those of foldable (claim 1).

  Thus, in the post pallet according to the present invention, first, a rectangular pallet, and at its four corners, an upright post and at least an upper end portion that surrounds and supports the post are provided with a U-shaped corner column. In the two posts and the corner pillars on the front side of the post pallet, the corner pillars are opposed to each other with the openings facing inward, and the posts can be folded inward on the pallet. Further, in the two posts and the corner pillars on the rear surface side, the corner pillars each have an opening facing forward, and both the posts can be folded forward on the pallet.

  In other words, each of the posts upright at the four corners of the pallet can be folded on the pallet. For example, when the post pallet itself is simply returned from the destination of the package, it is folded when the package is not loaded. It can be made compact, and it is possible to increase the amount loaded in a container or the like. Therefore, unlike the conventional product in which the shape is fixed even when no luggage is loaded and the amount of loading into the container cannot be increased, the cost associated with the return from the transport destination can be significantly reduced. As a result, in terms of cost, in particular, even if the transport destination is overseas, the returnable pallet can be returned and reused instead of being sent as a one-way pallet. For this reason, reuse, which is one of the solutions to recent environmental problems, becomes possible.

In addition, since one of the corner posts on the front side of the post pallet has a foldable part that can be folded to the outside of the pallet, the post can be folded onto the pallet and the foldable part can be folded outside the pallet. In this case, it is very easy to put in and out the load on the pallet without disturbing the folding part of the corner post, and the working efficiency is remarkably increased.
In addition, unlike the conventional product having the post portion 103FRa (see FIG. 18) of the post to be separated, in the present invention, all the posts are foldable and can be folded down. When a package is placed on a pallet, it will not be separated and then the separated post will not be lost.When transporting a package, the folded post or the collapsed corner post must be raised and assembled. It's easy because it's just nice.

  At this time, the post has a long hole formed on a side surface thereof, and the post is connected to the corner column so that the post can be rotated up and down by a post rotating shaft rod fitted into the long hole from the side surface of the corner column. Then, the post fixed by being inserted into the corner post can be pulled out to the U-shaped portion of the corner post and rotated onto the pallet (Claim 2).

  Thus, for example, a long hole is formed on the side surface of the post, and the post is connected to the corner column so as to be able to rotate up and down by a post rotating shaft rod fitted into the long hole of the post from the side surface of the corner column. Since the post fixed by inserting into the corner post can be pulled out to the U-shaped part of the corner post and rotated onto the pallet, the post and the corner post can be integrated more securely. The post is separated and never lost. And while the post can be fixed upright by the corner post, it can be pulled out and folded onto the pallet.

The collapsible portion of the corner post provided on the front side of the post pallet is a hinge, and can be engaged with and connected to the lower fixed leg portion (Claim 3).
Thus, if the collapsible part of the corner post provided on the front side of the post pallet is a hinge and is engaged and connected to the fixed leg part below, the collapsible part is separated. It can be moved to the outside of the pallet without any hindrance when loading and unloading.

The corner post provided on the front side of the post pallet and provided with a retractable part preferably further includes a lock mechanism that fixes the retractable part and the leg when engaged. (Claim 4).
In this way, if the retractable portion and the lock mechanism that fixes the leg portion when engaged are provided, the retractable portion is more reliably engaged with the leg portion without falling unintentionally. And can be fixed.

  The post pallet further includes left and right sideboard mechanisms for supporting the cargo in between, and each sideboard mechanism is formed at least on the sideboard for supporting the cargo and the pallet. A rail that extends in a lateral direction of the post pallet, a rail receiver that surrounds the rail, and an arm that connects the rail receiver and the side board, the rail receiver being slidable along the rail. The side board connected to the rail receiver via the arm is slidable along the rail, the rail has a rail hole, and the side board A sideboard fixing pin for fixing the position, and the sideboard fixing pin is inserted into the rail hole. It is, it can be assumed that the position of the sideboard is fixed (claim 5).

  In this way, it is desirable that the left and right sideboard mechanisms for supporting the cargo sandwiched between the left and right can be transported more stably. And if it is each sideboard mechanism as mentioned above, since the sideboard which supports a load is connected via the rail receptacle and arm which can slide along the rail extended in the horizontal direction of a post pallet, side The board can also slide along the rail. Furthermore, each rail has a rail hole, and the side board has a side board fixing pin for fixing the position of the side board, and the side board fixing pin is inserted into the rail hole. Since the position of the sideboard is fixed, for example, according to the width of the luggage, insert and remove the sideboard fixing pin, slide the sideboard to adjust its position and fix it It is possible, and it can be stabilized by pinching the load from the lateral direction.

At this time, the rail receiver and the arm are connected to each other via a sideboard rotating shaft rod, and the arm and the sideboard connected to the arm are integrally formed with the sideboard rotating shaft rod as an axis. Thus, it is preferable that the head is rotatable toward the inside of the post pallet.
If this is the case, the arm and the sideboard can be turned together with the sideboard turning shaft rod as an axis and turn toward the inside of the post pallet. The arm and the sideboard can be folded by rotating on the pallet, which can be made more compact when there is no luggage.

In the left and right sideboard mechanisms, the lengths of the arms may be different on the left and right.
In this way, if the arm length differs between the left and right sideboard mechanisms, for example, if the left / right side of the left / right side is made longer, the sideboard can be sufficiently separated from the pallet. Thus, it is possible to prevent the load from being taken in and out.

Moreover, it is desirable that the pallet, the post, the corner post, and the side board mechanism are integrated.
In this way, if the pallet, post, corner post, and sideboard mechanism are integrated, these components are not separated, and the loss of the components can be prevented. Since they are integrated, it is possible to save the trouble of searching for separated parts as in the prior art, and it is possible to efficiently assemble parts.

It is preferable that the pallet is provided with a fork guide.
As described above, if the pallet is provided with a fork guide, it is possible to easily and stably carry the post pallet on which the load is loaded or the post pallet itself using the forklift.

In addition, the pallet has a cushioning material for loading the cargo, and the cushioning material is positioned higher than the two posts on the front side of the post pallet folded inward on the pallet. (Claim 10).
In this way, the pallet has a cushioning material for loading the load, and the cushioning material is positioned higher than the two posts on the front side of the post pallet folded inward on the pallet. Then, even when the front two are folded, it is possible to take in and out the luggage without the post getting in the way.

  The post pallet of the present invention can be made compact, and the pallet can be made returnable and the cost required for the entire conveyance can be reduced. Furthermore, the assembly is simple and the baggage can be easily carried in and out.

Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited thereto. Here, a post pallet that is particularly suitable for loading / unloading luggage from the front side of the post pallet and from the right side will be described. However, it can also correspond to the case where the luggage is taken in and out from the left side, and in that case, the left and right may be switched.
FIG. 1 shows an outline of an example of the entire post pallet according to the present invention.
The post pallet 1 of the present invention includes a rectangular pallet 2 on which a load is placed and supports the bottom surface of the load. Posts 3 stand upright at four corners of the pallet. It has a corner post 4 that surrounds and supports it.
Further, on the left and right sides of the post pallet 1, there are provided sideboard mechanisms 5, 5 'for supporting the load so as to be sandwiched from the left and right side surfaces. In FIG. 1, only the left side board mechanism 5 (the right side is 5 ') is shown. Actually, a similar mechanism is provided on the right side as opposed to the left one.

  The material of the post pallet 1 is not particularly limited, and may be any material as long as it has strength or the like that can stably support the load, and is appropriately determined according to the type and weight of the load to be loaded. Can do. The material can be wood or the like, but if it is made of steel, for example, it is a material that has sufficient strength and is conventionally used, and each component in the present invention can be manufactured more easily. It is preferable because it is possible. Here, description will be made on the assumption that it is made of steel.

Hereinafter, each of the above components will be described in more detail.
First, the pallet 2 is formed in a lattice shape as shown in FIG. 1 by using rod-like members and welding them.
In the vicinity of the center of the grid pallet 2, two rod-like members are provided to connect the front side and the rear side (back side) of the post pallet 1 (that is, in the front-rear direction). The buffer material 7 is affixed. A load can be placed on the place where the cushioning material 7 is pasted and supported without damaging the load. As this buffer material, for example, a polyethylene foam can be used. Further, as an anti-slip of luggage, a rubber sheet or the like may be further bonded thereon. The cushioning material 7 and the anti-slip material can be the same as those used in the prior art.

  Further, the pallet 2 is provided with a fork guide 10, and a forklift pawl is inserted into the fork guide 10 so that the pallet 2 can be lifted and conveyed. The position and number of the fork guides 10 can be determined as appropriate, and may be provided according to the fork guide used.

In addition, in the pallet 2, the location where the cushioning material 7 is pasted on the surface, the number of rod-shaped members to be configured, and the like are not particularly limited, and are appropriately determined according to the size, shape, weight, etc. of the load to be loaded. be able to.
Moreover, the pallet 2 should just be what can support a load, and is not limited to a grid | lattice-like thing like FIG. For example, a planar one can be used. The manufacturing cost, weight, strength, and ease of transport can be taken into consideration, and it can be made appropriate.
The pallet 2 can have, for example, the same structure as that of the prior art, except for the position of the rail 25 of the sideboard mechanism 5 described in detail later.

Next, the post 3 and the corner post 4 will be described.
First, main features common to all the posts 3 and the corner posts 4 will be described with reference to FIGS. FIG. 2 shows an outline of the post 3, and FIG. 3 shows an outline of the corner post 4.
The post 3 has, for example, a prismatic shape, and a long hole 13 is formed on the side surface along the length direction of the post 3. The post 3 can be folded on the pallet 2 while being fixed and supported in an upright state by the corner post 4. The shape of the post 3 is not particularly limited, but if it is prismatic, it is easy to be stable when folded.

The four corner pillars 4 have a U-shaped shape (U-shaped part) 11 at the upper end portion, so that when the upright post 3 is pulled out from the corner pillar, The post 3 can be brought down toward the opening 15.
Further, the lower side of the corner post 4 is hollow at the cylindrical portion 12, and the lower end portion of the post 3 can be inserted into the hollow portion, thereby stably fixing the post 3 in an upright state. Can be supported. Further, the lower side of the corner post 4 is connected to the pallet 2. In the case of the post pallet 1 of FIG. 1 made of steel, the corner post 4 and the pallet 2 are welded and fixed.
In addition, although the lower end part of the corner pillar 4 is trapezoidal so that the post pallet 1 may be stabilized, any shape that can stabilize the post pallet 1 may be used.
A post-rotating shaft rod 14 is inserted into the corner post 4 so as to be fitted into the elongated hole 13 of the post 3 from the side surface of the corner post 4. 2 and 3, since the post 3 and the corner post 4 are separately illustrated, the elongated hole 13 of the post 3 and the post pivot shaft 14 of the corner post 4 are not engaged. As shown in FIGS. 4 and 5, these are integrated with each other.

Here, the relationship between the vertical movement and rotation of the post 3 and the corner post 4 will be described in more detail.
FIG. 4 shows a state in which the lower end portion of the post 3 is inserted into the hollow portion of the cylindrical portion 12 of the corner post 4 and is fixed upright. FIG. 5 shows a state in which the lower end portion of the post 3 is extracted from the hollow portion of the cylindrical portion 12 of the corner post 4 to the U-shaped portion 11 and is rotated.
When the post 3 is erected, as shown in FIG. 4, the post 3 is inserted into the hollow portion of the corner post 4, and at this time, the post pivot shaft 14 of the corner post 4 is located above the elongated hole 13 of the post 3 ( Or it is located at the upper end).
On the other hand, when the post 3 is folded, as shown in FIG. 5, first, the post 3 is pulled out from the hollow portion of the corner post 4 to the U-shaped portion 11, thereby reaching the lower end of the long hole 13 of the post 3. The post 3 is rotated about the post-rotating shaft rod 14 of the corner column 4 that has moved relatively. With such a structure, the post 3 can be rotated in the direction of the opening 15 of the U-shaped portion 11 of the corner post 4 without being separated from the pallet 2. In addition, the long hole 13 can also be made into the shape as FIG. 2, and can also be made into the shape where the front-end | tip was notched and formed in the shape of a character like FIG. With such a character, it is possible to prevent the post 3 from interfering with the inner surface of the corner post 4 when the post 3 is rotated.

As described above, the post 3 and the corner post 4 located at the four corners of the pallet 2 have the above-mentioned common features. FIG. 6A is a front view of the post pallet 1 viewed from the front side. However, for easy understanding, only the post 3 on the front side (3FL on the left and 3FR on the right), the corner post 4 (4FL on the left and 4FR on the right) and the pallet 2 are shown.
As shown in FIG. 6A, in the two corner pillars 4FL, 4FR located on the front surface side of the post pallet 1, the opening portions 15 face each other inward. For this reason, when each of the posts 3FL and 3FR is folded, it can be rotated toward the inside of the post pallet 1 and folded on the pallet 2 in the direction of the opening 15.

Further, in the two corner pillars 4RL and 4RR on the rear surface side, the opening 15 faces the front of the post pallet 1, and each of the posts 3RL and 3RR rotates both forward and pallet. 2 can be folded. FIG. 6B shows how the right post 3RR on the rear surface side rotates, but the left post 3RL on the rear surface side can also rotate in the same manner.
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 Two plate-like backrests 6 for supporting the back side are provided with a cushioning material 7 on the surface. The backrest 6 is provided so as to incline 5 ° from the vertical direction (from the posts 3RL and 3RR), for example, when the post 3 is fixed upright. With such an inclination, it is possible to incline and support a load such as a glass substrate on the backrest 6. Of course, the number and shape of these auxiliary members 9 and the backrest 6, the inclination of the backrest 6 and the like are not particularly limited.
The two posts 3RL and 3RR on the rear side can be folded forward together with the backrest 6 and the like.

Although the height position of the post-rotating shaft rod 14 of the corner column 4 that serves as the axis on which the post 3 rotates is not particularly limited, for example, on the front side, as shown in FIG. It can be provided such that the height position of the post pivot shaft 14 in the left corner column 4FL is higher than the height position of the post pivot shaft 14 in the right corner column 4FR. If it is such, since each post | mailbox 3FL and 3FR pile up in parallel when it folds, it is preferable since it can fold more compactly.
Also on the rear side, the long hole 13 of the post 3 is formed to be bent in a U-shape, and when the post 3 is folded forward or reversely assembled, the post 3 becomes the inner surface of the corner post 4. Can be prevented from interfering with.

  In the post pallet 1 of the present invention, the right corner post 4FR on the front side (corresponding to the side for loading and unloading the luggage in this case) is composed of a retractable portion 16 and a leg portion 17 as shown in FIG. These are connected by a hinge 18. As shown in the explanatory view of the structure of the corner post 4FR in FIG. 7 (when viewed from the front side of the post pallet 1), there is a leg 17 below the corner post 4FR and is connected (welded) to the pallet 2. And fixed. A tiltable portion 16 is provided above the corner post 4FR and is connected via a hinge 18 so as to engage with the leg portion 17. As described above, the post 3FR rotates inward and is folded on the pallet 2, but conversely, the retractable portion 16 can be tilted toward the outside of the pallet. It has become.

Thus, since the post 3 can be folded inward and the retractable portion 16 of the corner post 4 can be tilted outward, the post 3FR and the corner post 4FR (possible) when the luggage is put in and out of the corner post 4FR. It is possible to perform the work without the fold 16) getting in the way.
Further, with such a structure, it is possible to prevent a post pallet having a wider width than necessary for ensuring workability. In other words, the size of the post pallet can be made as small as possible, and even when loading the same size of luggage, a more compact post pallet can be used. It can be further increased.

  By the way, as shown in FIG. 6A, when the front side posts 3FL, 3FR are rotated and folded, the cushioning material 7 provided on the pallet 2 is positioned higher than these posts 3FL, 3FR. In this case, it is preferable that the luggage can be taken in and out on the cushioning material 7 without both the posts getting in the way. FIG. 6C shows an example of the positional relationship between both posts and the cushioning material when the cushioning material 7 is provided at a position higher than the posts 3FL and 3FR.

  In addition, when the post 3FR is fixed upright, such as when the cargo is loaded and transported together with the post pallet 1, conversely, the post 3FR can be supported without the tiltable portion 16 falling down in the corner post 4FR. It is preferable to provide a lock mechanism 19 on the corner post 4 so that the tiltable part 16 and the leg part 17 are fixed in an engaged state. FIG. 8 shows a state in which the collapsible part 16 and the leg part 17 are locked by the lock mechanism 19. FIG. 8 shows a case when viewed from the front side of the post pallet 1.

  The lock mechanism 19 is not particularly limited as long as it can fix the engaged retractable portion 16 and the leg portion 17. For example, a pair of cylindrical locking members 20 such that the positions of the inner cavities coincide with the side surfaces of the foldable portion 16 and the leg portion 17 when the foldable portion 16 and the leg portion 17 are engaged with each other. And a structure that is locked by inserting a pin 21 from above into a hollow inside the cylindrical member 20. With such a structure, it can be easily locked, and it is convenient because it is only necessary to remove the pin 21 when releasing the lock. For example, if only the head of the pin 21 is made larger than the diameter of the cavity, the head of the pin 21 catches on the upper end of the cylindrical member 20 and can be securely locked without falling off. .

Separately from this, a locking mechanism can also be provided in the posts 3RL and 3RR on the rear surface side.
FIG. 9 shows an example of the locking mechanism. It is the figure seen from the front side of the post pallet 1, and the left post 3RL is taken as an example. An insertion port 23 is formed on the side surface of the corner post 4RL so that the pin 22 can be inserted by sliding in the horizontal direction. When the post 3RL stands upright and is fixed to the corner post 4RL, this insertion port is provided. The pin 22 is inserted into the hole 23 and the pin 22 is inserted into the hole provided at the corresponding position of the post 3RL so that it can be locked.

Next, the sideboard mechanisms 5, 5 ′ will be described.
Each of the left and right sideboard mechanisms 5, 5 ′ (5 on the left and 5 ′ on the right) is mainly arranged on the side of the load as shown in FIG. 1 and the plan view of FIG. 11 showing the outline of the sideboard mechanism. A rail 25 that is formed on the side board 24 and the pallet 2 supported from the lateral direction and extends in the lateral direction (left and right direction) of the post pallet 1, surrounds the rail 25, and is slidable along the rail 25. The rail receiver 26 and the side board 24 are configured by an arm 27 that connects the rail receiver 26 and the side board 24.

The side board 24 has a cushioning material 7 affixed to the surface on the luggage side, so that it can be supported from the side without damaging the luggage. Here, FIG. 10 shows the relationship between the side board and the rail when the side board 24 is viewed from the back side. In the center of the lower surface of the side board 24 on the back surface side, a pin (side board fixing pin 28) that can be loaded and unloaded with a spring mechanism is provided.
The rail 25 is formed with a rail hole 29 having a size capable of inserting at least the sideboard fixing pin 28. The number of rail holes 29 is not particularly limited, and a plurality of rail holes 29 can be provided along the rails 25.

12 shows a cross-sectional view of the rail 25, the rail receiver 26, and the arm 27 when viewed from the arrow A in FIG. The rail receiver 26 is formed in a cylindrical shape so as to surround the rail 25 and can slide along the rail 25. A saddle-shaped end portion 26 ′ extending from the cylindrical portion of the rail receiver 26 to both sides is connected to an arm 27 via a sideboard rotating shaft rod 30.
The other side of the arm 27 is connected (welded) to the side board 24, and the side board is integrated with the arm 27.

With the above configuration, when the rail receiver 26 is slid along the rail 25, the arm 27 connected to the rail receiver and the side board 24 connected to the arm 27 are also connected along the rail 25 in the same manner. It is possible to slide.
The side board 24 can be fixed at a desired position by inserting the side board fixing pins 28 provided on the side board 24 into the appropriate rail holes 29. This fixed position can be appropriately determined according to the width of the load to be placed on the pallet 2. When the fixing position is changed, the side board fixing pin 28 is once extracted from the rail hole 29, slided to adjust the position, and then inserted into another rail hole 29.

  Further, as shown in FIG. 12, the rail receiver 26 and the arm 27 are connected by a sideboard rotation pin 30, so that the arm 27 is placed inside the post pallet 1 with the sideboard rotation pin 30 as an axis. It is possible to turn it toward. At this time, as described above, since the side board 24 is connected to the arm 27, the side board 24 rotates together with the arm 27. Thus, by rotating the arm 27 and the side board 24 inward, the side board mechanisms 5 and 5 ′ can be folded on the pallet 2, and can be made more compact when not in use. FIG. 13 shows a state where the right side board mechanism 5 'is folded. FIG. 13 shows a case when viewed from the front side of the post pallet 1.

  Since the arm 27 connected to the side board 24 is connected to the rail receiver 26 by the side board rotating shaft rod 30, the side board rotating shaft rod 30 and the side board 24 are connected to each other. Are connected to each other at a position separated by the arm 27, and the side board 24 can be prevented from easily falling inward during work.

In the left and right sideboard mechanisms 5, 5 ′, the length of the arm 27 can be different between the left and right sides. With this structure, that is, for example, if the arm 27 of the right sideboard mechanism 5 ′ is made longer, the sideboard 24 is arranged at a position further away from the pallet 2 in the right direction (outside the pallet). Thus, the sideboard 24 can be easily and safely loaded and unloaded without disturbing the sideboard 24, and the work can be efficiently performed.
Alternatively, the left and right sideboard mechanisms 5 and 5 ′ may be capable of sliding the sideboard 24 along the rail 25, for example, in conjunction with the left and right.
The difference in shape and interlocking between the left and right sideboard mechanisms 5 and 5 ′ can be determined as appropriate in consideration of work efficiency, manufacturing cost, type of load to be loaded, and the like.

  The pallet 2, the post 3, the corner post 4, and the side board mechanisms 5, 5 ', which have been described in detail above, are preferably integrated. In particular, in the conventional product, the post 3 and the sideboard 24 of the sideboard mechanism are separable, and thus may be lost when separated. In the present invention, these are integrated. Therefore, the parts are not separated in the first place, and therefore it is possible to effectively prevent the parts from being lost.

Hereinafter, a procedure for placing a load on the post pallet 1 of the present invention will be described. The load placed on the post pallet 1 is not particularly limited. For example, a case where a load is made by stacking a plurality of glass substrates into a block will be described as an example.
First, a glass substrate that is a load is stacked by stacking substrates with a polyethylene sheet that is slightly larger than the glass substrate interposed therebetween, and the entire stacked glass substrate is further wrapped with a vinyl sheet. Then, it is put together in a block shape by binding with a PP band.

  On the other hand, in the post pallet 1, first, the right post 3 FR on the front side is folded inward, and the foldable part 16 of the corner post 4 FR is tilted to the outside of the pallet 2. The other posts 3 may be fixed upright. In the right side board mechanism 5 ′, the side board 24 is separated from the pallet 2 by sliding the rail receiver 26 to the rightmost side of the movable range of the rail 25.

In this way, after making preparations for easy loading and unloading, the packages are actually placed on the pallet 2. For example, it may be mounted using a human hand or a forklift. The luggage is supported by sandwiching the back side against the backrest 6 and sandwiching the left and right side surfaces from the left and right using the side board mechanisms 5 and 5 '. At this time, the position of the side board 24 is fixed at an appropriate position by inserting the side board fixing pin 28 into the rail hole 29.
In addition, the tiltable portion 16 of the right-side corner post 4FR on the front side that has been tilted first is raised and engaged with the leg portion 17 to be connected, and then the connecting portion is fixed by the lock mechanism 19. Further, the post 3FR is raised and the lower end portion is fixed by inserting it into the corner post 4FR so as to stand upright.
Then, the loaded cargo is bound together with the post pallet 1 using a PP band or the like, and further stabilized, and then the forklift claw is inserted into the fork guide 10 and the cargo is conveyed along with the post pallet 1 using the forklift.

On the other hand, when returning from the transport destination, when not loading the luggage, it is folded and made compact. For example, first, the sideboard mechanism 5, 5 ′ is folded on the pallet 2 by rotating the sideboard 24 and the arm 27 inward. Then, the front side posts 3FL and 3FR are pulled out to the U-shaped portions 11 of the corner pillars 4FL and 4FR, and alternately folded inwardly, and the back side post 3 is also rotated forward in the same manner to form a sideboard mechanism. 5 and 5 'can be folded over.
In such a state, the height of the post pallet 1 can be reduced to, for example, half or less, and the amount loaded in the container at a time can be remarkably increased. As a result, the cost for return can be reduced. In particular, when a package is transported overseas, it can be used not as a one-way pallet but as a returnable pallet to be returned from a transport destination in terms of cost ( (See FIG. 14).

The present invention will be described in detail below with reference to examples of the present invention, but these examples do not limit the present invention.
(Example)
Regarding the post pallet of the present invention made of steel as shown in FIG. 1, the number of units that can be loaded into a container when returning from the transport destination was examined.
At the time of return, the container on which the post pallet is loaded is 40 feet long and has a high cube standard (12000 mm (length) × 2340 mm (width) × 2585 mm (height)).

  As the post pallet, one for conveying a 50 inch (116 cm) glass substrate was prepared. In this post pallet, the dimensions when loading the luggage, that is, when the parts such as the post, the corner post, and the sideboard mechanism are raised and assembled are 750 mm (depth) × 1310 mm (width) × 950 mm (height). .

  On the other hand, when the post, sideboard mechanism, etc. are rotated inside the post pallet and folded on the pallet to make it compact, the dimensions should be 750 mm (depth) × 1310 mm (width) × 415 mm (height). did it. That is, it can be seen that the height of the post pallet can be reduced to about 44% (415 mm / 950 mm) when folded compared to when loading the luggage.

From this point of view, in terms of volume, when loading a load, as shown in the plan view when loading a post pallet in FIG. 15, 27 units per stage, the total number is 54 units (3 units × 9 units). It is possible to stack 162 post pallets (3 units x 9 rows x 6 levels) in a container when folded by return (the number of units per stage when loading is the above) But the number of stackable stages is different). In addition, an example of the state which piled up post pallets 1 is shown in FIG. The upper end portion of the corner post of the lower post pallet is inserted into the lower leg portion of the corner post of the upper post pallet so as to be stably stacked.
In this way, the number of post pallets per container to be loaded when returning can be significantly improved (three times in this case) than when loading and transporting packages, and the post pallet can be efficiently transferred from the transport destination. Can be returned.

(Comparative example)
When returning the conventional post pallet from the transport destination, the number of units that can be loaded in the same container as in the example was examined.
The dimensions of this conventional post pallet are 750 mm (depth) × 1350 mm (width) × 1000 mm (height). The size is slightly larger than the present invention in order to secure a space for loading and unloading. In the conventional product, one post can be separated as shown in FIG. 18, but the other post cannot be folded. Therefore, when loading a load or when returning it, the load is loaded. Even when it is not, the overall size cannot be changed.

Therefore, in the conventional product, even when returned, as shown in the plan view of FIG. 16, there are 25 units per step, and at most 50 units (25 units × 2 steps).
Also, even if the post pallet has a size of 750 mm (depth) x 1310 mm (width) x 950 mm (height) as in the case of loading the baggage in the embodiment, the size cannot be reduced at the time of return, so 54 units (3 units x 9 rows x 2 stages) can only be loaded into a container by volume.

  In this way, in the conventional product, as shown in the comparative example, most of the posts are welded to the pallet and cannot be folded. The size cannot be reduced. Therefore, the return efficiency is poor, and it cannot be used as a returnable pallet from the viewpoint of cost, and must be a one-way pallet.

  However, in the case of the post pallet according to the present invention, as shown in the embodiment, the post pallet can be folded to be compact when returned, so that in terms of volume, the number of stackable containers per container is increased. be able to. As a result, the cost at the time of return can be reduced, and even if it is used as a returnable pallet, it is possible to sufficiently increase the profit.
