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. 20 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. 21, 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.
Also, as shown in FIGS. 20 and 21, etc., there are separable parts such as the post part 103FRa of the post and the side board 105. However, because of such a structure, there is a problem that the parts are lost. I was sorry. 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 achieve the above object, the present invention provides a post pallet for loading a load, and at least includes a rectangular pallet and four upright posts at the four corners of the pallet. And at least the upper end portion of the four posts and corner pillars, the two of the four posts and corner pillars provided on the front side of the post pallet for loading and unloading the cargo. Each of the letter-shaped corner pillars is opposed to each other with the opening facing inward, the posts are foldable inwardly on the pallet, and at least one corner pillar is folded inwardly. The post has a foldable part that is foldable on the post, and in the two posts and the corner post on the rear side, each of the U-shaped corner posts has an opening facing forward. Before Providing a post pallet, characterized in that both on the pallet is intended for foldable forward.

  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 at a time. 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.

  Furthermore, since at least one corner column on the front side of the post pallet has a foldable part that can be folded on a post folded inward, the post is folded on the pallet and the foldable part is further folded thereon. If this is the case, it is very easy to load and unload the luggage on the pallet without disturbing the folding part of the corner post, and the work efficiency is remarkably increased. In particular, the corner post can be folded inward on the post so that, for example, when working with the corner post folded, compared to the case where the folding part is folded outward, Further, it is possible to more effectively prevent the forklift or the operator's foot from coming into contact, and to prevent the fallable part from being damaged.

  Note that, unlike the conventional product having the post portion 103FRa (see FIG. 21) of the post to be separated, in the present invention, all the posts are foldable, and the foldable portion can be folded inward. For example, when a load is placed on a pallet, it is not possible to lose the post after it has been separated, and when transporting the load, a folded post or a corner post folded inward is used. It is easy because you only have to wake up and assemble.

At this time, it is preferable that the two corner pillars on the front side each have a foldable part that can be folded on the post folded inward.
If this is the case, for example, during work such as loading / unloading of luggage, the two posts on the front side are folded inward, and the foldable parts of both corner posts on the front side are folded inward. be able to. That is, on both the left and right sides of the front side, both the post and the corner post can be folded inward, so that it can be further prevented from interfering with work, and work efficiency can be extremely enhanced.

  Further, the post has a long hole formed on a side surface thereof, and the post can be rotated up and down with respect to the corner column by a post rotating shaft rod inserted into the long hole of the post from the side surface of the corner column. The post that is connected and 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.

  In such a case, the post and the corner post are more reliably integrated by the post rotating shaft rod, and the post is not separated and lost. And while the post can be fixed upright by the corner post, it can be pulled out and folded onto the pallet.

  In addition, the corner column having the retractable portion has a fixed leg portion that supports the retractable portion, and the leg portion has a head having an outer dimension smaller than the inner dimension of the tiltable portion. And a retractable portion receiver for supporting the retractable portion fitted so as to surround the head, and the post-rotating shaft rod is connected to a leg from a short hole formed on a side surface of the retractable portion. Through the hole formed in the side surface of the head of the part, the retractable part is connected to the fixed leg part so as to be able to rotate up and down by being inserted into the elongated hole of the post. It is preferable that the foldable portion fitted so as to surround the head portion is pulled out from the foldable portion receiver and is rotatable on the folded post.

  If this is the case, in the corner column, the pivot part and the fixed leg part, including the post, are more reliably integrated by the post pivot shaft rod, and the fallable part is separated and lost. Nor. In addition, the retractable portion can be supported by the retractable portion receiver while being fitted so as to surround the head portion of the leg portion, and the retractable portion can be fixed to the leg portion. On the other hand, the retractable part can be pulled out from the retractable part receiver and folded on a post folded inward.

  Further, the retractable portion receiver of the leg portion has a bottom surface support plate that supports the bottom surface of the retractable portion and a side surface support plate that supports the side surface of the retractable portion, and the bottom surface support plate is formed of the corner pillar. Since the side support plate is fixed to the outer surface of the bottom surface support plate, a gap is formed between the head portion and the side surface support plate. The part is preferably fitted in a gap formed by the head and the side support plate, and the bottom surface is supported by the bottom support plate.

  If this is the case, as the retractable part receiver, the retractable part can be fitted into the gap between the leg head and the side support plate, and the bottom surface of the retractable part can be supported by the bottom support plate. Since it can do, it can fix to a leg part more reliably. Further, even when a load is applied to the post and further to the retractable portion, particularly in the direction opposite to the opening of the corner post, it can be supported by the side support plate.

  At this time, the retractable portion has a shape in which the lower end is convex downward at least on the side surface where the short hole is formed, and the head of the leg portion is at least on the side surface where the hole is formed The concave portion further has a concave shape corresponding to the convex shape of the lower end of the retractable portion, and when the retractable portion is fitted to the head, the convex shape of the lower end becomes the concave shape of the head. It is preferable that it is fitted and fixed.

  If this is the case, when the retractable part is fitted to the head of the leg, the convex shape of the lower end of the retractable part is fitted and fixed to the concave shape of the head. Is positioned more stably, and the fixing to the leg portion is further ensured.

  In addition, the post pallet further includes sideboard mechanisms for supporting the cargo with the left and right sides, and each sideboard mechanism is formed on at least a 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 It has a sideboard fixing pin for fixing the position, and the sideboard fixing pin is inserted into the rail hole. And in, it can be assumed that the position of the side board is fixed.

  In this way, it is desirable that the left and right sideboard mechanisms for supporting the baggage are sandwiched between the left and right, because the baggage 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.

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 integrated with the sideboard rotating shaft rod as an axis. Thus, it is preferable that it 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 addition, the post pallet further includes sideboard mechanisms for supporting the cargo with the left and right sides, and each sideboard mechanism is formed on at least a sideboard for supporting the cargo and the pallet. A rail extending in the lateral direction of the post pallet, and a connecting member that surrounds the rail and is directly attached to the side board, and the connecting member is slidable along the rail, The side board is slidable along the rail, the 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 sideboard fixing pin is inserted into the rail hole so that the position of the sideboard is fixed. Rukoto can.

  If the sideboard mechanism as described above is provided on the left and right, the connecting member attached directly to the sideboard can slide along the rail, and the sideboard can also slide along the rail. The position of the side board can also be fixed, and it is possible to securely hold the cargo from the lateral direction and stabilize it.

In the left and right sideboard mechanisms, the length of the arm or the connecting member may be different on the left and right.
In this way, if the length of the arm or connecting member differs between the left and right sideboard mechanisms, for example, if the left or right side of the left or right side is made longer, the sideboard will be sufficiently separated from the pallet. 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.

The pallet is preferably 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.

Further, the pallet has a cushioning material for loading a load, and the cushioning material is folded onto the two posts on the front side of the post pallet folded inward on the pallet and the post. It is preferable that it is located higher than the corner column.
In this way, the pallet has a cushioning material for loading the load, and the cushioning material is folded onto the two posts on the front side of the post pallet folded inward on the pallet and the post. As long as it is positioned higher than the corner pillars, it is possible to put in and out the luggage without disturbing the posts even when the two front pillars and the corner pillars are folded.

  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 cargo can be carried in and out very easily.

Hereinafter, embodiments of the present invention will be described, but the present invention is not limited thereto.
A conventional post pallet 101 as shown in FIG. 20 is used as a so-called one-way pallet, which has been expensive. In addition, there are problems that separable parts such as the post portion 103FRa as shown in FIGS.

  Further, as disclosed in Japanese Patent Application Laid-Open No. 2008-260537, the post can be laid down on the pallet, and the upper part of the post on the front side of the post pallet is placed on the outside of the post pallet by a hinge. A structure that can be folded is disclosed. FIG. 22 shows an example of a corner post of this post pallet.

As shown in FIG. 22, the corner column 204 has a corner column upper portion 216 and a fixed corner column lower portion 217, and the corner column lower portion 217 and the corner column upper portion 216 are engaged with each other by a hinge 218. By passing the pin 221 through the cylinder 220, the corner column upper portion 216 is fixed upright on the corner column lower portion 217.
Then, at the time of work such as loading / unloading of luggage, the pin 221 can be pulled out as shown in FIG. 23, and the top of the corner post 216 can be brought outside the post pallet via the hinge 218, so that the corner post 204 does not interfere with the work. Has been.

However, in such a conventional post pallet, the corner post is damaged.
When the present inventors investigated the cause of this, it was found that the corner column upper part that was tilted to the outside of the post pallet contacted the forklift, the worker's feet, or the like during the work. Furthermore, in the upper part of the corner pillar, the part that engages with the lower part of the corner pillar (the part surrounded by the dotted line in FIG. 23) protrudes from the height position of the pallet, and is easily damaged when coming in and out of the luggage. I also found it in the way of work.

Therefore, the present inventors do not disturb the corner post outside the post pallet, but instead tilt it inward and fold it on the folded post, so that it does not interfere with the forklift or the worker, and works more efficiently. Found that can be done.
Also, at least the upper end of the corner post is U-shaped, and the post is folded inward on the post pallet so that it surrounds the post, and the corner post can be folded inward as well. If the portion can be folded, the protrusion from the height position of the pallet can be eliminated as in the portion surrounded by the dotted line in FIG. In other words, the height position from the pallet to the corner column folded inward can be made lower than before, and it is easy to load and unload the cargo on the pallet, and the work efficiency can be further improved. Naturally, the contact between the load and the corner post can be prevented, and in this respect as well, it is possible to prevent the corner post from being damaged and to prevent the load from being damaged.
The present inventors found these things and completed the present invention.

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. In other words, this is a case of a post pallet having a structure in which the right corner column on the front side can be folded inward. 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. Furthermore, for example, both the left and right corner pillars on the front side can be folded inward so that the luggage can be easily taken in and out from the entire front side or both the left and right sides.

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. 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 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. In the post pallet of the present invention, at least one of the two corner pillars provided on the front side has a foldable part that can be folded inwardly. In the case of the corner pillar having the retractable part, the structure is different from the other corner pillars not having the retractable part, but the relation with the post as the corner pillar is the same. Are described together here. The unique structure of the corner post having the retractable part and the unique relationship with the post will be described later.

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 to be described later, these are engaged with each other and integrated.

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 can be rotated with the post-rotating shaft rod 14 of the corner column 4 relatively moved as an axis. 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.

Next, the unique structure of the corner column having the retractable part and the unique relationship with the post supported by the corner column will be described.
First, a unique structure of a corner column having a retractable part will be described. FIG. 7 shows an outline of an example of main components of a corner post having a retractable part. Of the two corner pillars on the front side, at least one has a foldable part that can be folded inward. Here, the right corner pillar 4FR on the front side (in this case, on the side where the luggage is taken in and out) The case where (corresponding) has a retractable part will be described.
The right corner column 4FR on the front side is roughly divided into a tiltable part and a leg part that supports it from below, and the leg part is connected (welded) to the pallet and fixed.
FIG. 7A shows the retractable part, and FIGS. 7B and 7C show the leg part.

As shown in FIG. 7A, first, the retractable portion 16 has a U-shaped shape so as to surround the post 3, and the direction in which the post 3 falls when the post 3 is folded, that is, An opening 15 ′ is provided toward the inside of the post pallet 1. A short hole 18 is formed in the side surface along the length direction of the retractable portion 16. A post-rotating shaft rod 14 is fitted into the short hole 18. The shape of the short hole 18 is not limited.
Moreover, although the thickness below the foldable part 16 is increasing, this is adjusted so that it may be stably fitted and fixed to the foldable part receiver provided in the leg part mentioned later. . For example, a U-shaped cover 36 having an appropriate thickness is provided by welding or the like on the outer side below the foldable portion 16, and the thickness is adjusted appropriately so that the foldable portion receiver is securely fitted and fixed. be able to.

On the other hand, as shown in FIG. 7B, the leg portion 17 has a head portion 19 first. The head portion 19 has an outer size smaller than the inner size of the foldable portion 16, and when the foldable portion 16 and the leg portion 17 are engaged, the foldable portion 16 is covered from above, and is foldable. It is surrounded by the part 16. The head 19 has a U-shape so as to surround the post 3, and in the same manner as the foldable portion 16, the direction in which the post 3 falls when the post 3 is folded, that is, the inside of the post pallet 1. An opening 15 '' is provided towards the front.
A hole 20 is formed on the side surface. A post-rotating shaft rod 14 is fitted into the hole 20.

  And below this head 19, it is hollow by cylindrical part 12 'like other corner pillars, The lower end part of post 3 can be inserted in this hollow part, and post 3 Can be stably fixed and supported in an upright state. Furthermore, it is the same structure as other corner pillars also about the point fixed by welding with the pallet 2 and the lower end part being a trapezoid.

Further, the leg portion 17 further has a retractable portion receiver 31. The foldable part receiver 31 is not particularly limited as long as it can support the foldable part 16 that is covered by the head 19 from above and surrounds the head 19. For example, as shown in FIG. 7C, a bottom surface support plate 32 that supports the bottom surface of the retractable portion 16, and a side surface support plate 33 that supports the side surface of the retractable portion 16 (the surface opposite to the opening 15 '). It can consist of.
A bottom support plate 32 is fixed to the opposite side of the opening of the corner pillar, that is, the surface of the leg 17 opposite to the opening 15 ″ by welding or the like, and a side surface is provided on the outer surface 34 of the bottom support plate 32. The support plate 33 is fixed by welding or the like. Since the side support plate 33 is fixed so that the upper portion protrudes upward from the bottom support plate 32, the protruding side support plate 33 and the head 19 form a gap 35.
The bottom surface support plate 32 and the side surface support plate 33 are not particularly limited in shape, size, and the like. For example, the side support plate 33 can be T-shaped.

Here, FIG. 8 shows a state in which the retractable portion 16 and the leg portion 17 are engaged and the retractable portion 16 is supported by the leg portion 17. As shown in FIG. 8, the same post-rotating shaft rod 14 is actually fitted into the short hole 18 of the retractable portion 16 and the hole 20 of the leg portion 17, thereby fixing the retractable portion 16. The formed leg portions 17 are integrated to form a corner post 4FR. At this time, the post-rotating shaft rod 14 is positioned above (or at the upper end of) the short hole 18 of the retractable portion 16.
As can be seen from FIG. 8, the corner post 4FR has a U-shaped shape (U-shaped part) 15 at the upper end, and the opening 15 of the corner post 4FR is formed by the folding part 16. The opening 15 ′ and the opening 15 ″ of the leg 17 are formed together.

  Further, the retractable portion 16 is covered so as to surround the head portion 19 from above the leg portion 17, and a gap between the head portion 19 and the side surface support plate 33 on the side opposite to the opening portion 15 of the corner post 4FR. 35, the bottom surface is supported by the bottom surface support plate 32, and the side surface (surface opposite to the opening 15 ') is supported by the side surface support plate 33.

Here, other embodiments will be described with respect to the retractable part and the leg part.
FIG. 24 shows another example of the retractable part. 24, a step 37 is formed in the middle in the length direction, and the inner dimension of the upper portion of the retractable portion 16 ′ is smaller than the lower portion through the step 37. . However, it has an internal dimension that can sufficiently surround the post above. Then, when the foldable portion 16 ′ and the leg portion are engaged, the leg head having an outer dimension smaller than the inner dimension below the foldable portion 16 ′ is placed below the foldable portion 16 ′. It can be covered with a part.

FIG. 25A shows a case where the retractable portion 16 ′ of FIG. 24 is viewed from the B arrow. That is, it shows the surface on the opposite side of the opening.
FIG. 25B shows a state where the retractable portion 16 ′ and the leg portion of FIG. 24 are engaged. Here, only the bottom surface support plate 32 ′ is shown for the legs so that the relationship between the retractable portion 16 ′ and the bottom surface support plate 32 ′ at the time of engagement can be easily understood.
As shown in FIG. 25 (B), the bottom surface support plate 32 ′ of the leg has a convex shape, for example. On the other hand, as shown in FIG. 25A, the retractable portion 16 ′ has a concave shape corresponding to the convex shape of the bottom surface support plate 32 ′ on the side opposite to the opening. When the retractable portion 16 ′ is fitted to the leg portion, the concave shape of the retractable portion 16 ′ is fitted to the convex shape of the bottom surface support plate 32 ′ of the leg portion. As a result, the retractable portion can be more securely fixed and fitted to the leg portion.

FIG. 26A shows in more detail the lower end of the side surface in which the short hole of the foldable portion 16 ′ of FIG. 24 is formed. FIG. 26 (B) shows a side surface in which a hole is formed in the head portion of the leg portion 17 ′ to which the retractable portion 16 ′ is fitted. FIG. 26C shows a state in which the retractable portion is engaged with the leg portion.
First, as shown in FIG. 26 (A), the retractable portion 16 ′ has a shape in which the lower end is convex downward (convex shape 38) on the side surface where the short hole 18 is formed.
On the other hand, as shown in FIG. 26 (B), the head portion 19 'of the leg portion 17' has a concave shape corresponding to the convex shape 38 at the lower end of the retractable portion 16 'on the side surface where the hole 20 is formed. 39 is formed. The concave shape 39 can be provided, for example, by attaching a U-shaped member by welding or the like.
Then, as shown in FIG. 26C, when the retractable portion 16 ′ is fitted to the head 19 ′, the convex shape 38 of the tiltable portion 16 ′ can be fitted to the concave shape 39 of the head 19 ′. it can. As a result, the position of the tiltable portion 16 'can be more stably fixed.

  The combination of the convex shape at the lower end of the foldable portion and the concave shape at the head portion of the leg portion may be formed only on one side of the side surfaces where the short holes and holes are formed, or on both sides. It may be formed. Furthermore, it can also be formed on the surface opposite to the opening. If necessary, the specific shape, number, and surface to be formed can be determined each time.

Further, the relationship between the vertical movement and rotation of the retractable part and the leg part will be described. Here, the retractable portion 16 and the leg portion 17 shown in FIG. 7 will be described as an example.
FIG. 9 shows a state in which the retractable portion 16 is pulled out of the retractable portion receiver 31 of the leg portion 17 and rotated.
When folding the retractable part 16 inside the post pallet 1, as shown in FIG. 9, first, the retractable part 16 is pulled out from the retractable part receiver 31 of the leg part 17, thereby The tiltable portion 16 is rotated about the post-rotating shaft rod 14 that has moved relatively to the lower end of the short hole 18 as an axis. With such a structure, the retractable portion 16 can be rotated in the direction of the opening 15 of the corner post 4FR.

Next, a unique relationship between the corner column having the retractable portion and the post will be described.
FIG. 10 shows a state where the corner post having the retractable portion and the post are engaged. That is, FIG. 8 shows a state in which the retractable portion 16 and the leg portion 17 are engaged and the retractable portion 16 is supported by the leg portion 17, but the post 3 is further engaged inside the leg portion 17. It is in a state. As shown in FIG. 10, the post-rotating shaft 14 is formed from the side surface of the corner pillar (in this case, through the short hole 18 formed on the side surface of the retractable portion 16 and the hole 20 formed on the side surface of the leg portion 17. ) It is inserted in the long hole 13 of the post 3. By this post-rotating shaft rod 14, the tiltable portion 16 and the leg portion 17 of the corner post 4FR and the post 3 are engaged with each other and integrated.

When the post 3 is erected, the lower end of the post 3 is inserted into the cylindrical portion 12 ′ of the leg portion 17 so that it can be stably fixed and supported. Thus, the post 3 is supported at the lower end by the leg 17, and is surrounded by the U-shaped retractable part 16 supported by the leg 17 above the post 3.
When the post 3 is folded inward on the pallet 2, the upright post 3 can be pulled out from the cylindrical portion 12 ′ of the leg portion 17 to the U-shaped portion and tilted toward the opening 15. The post 3 is folded in the same manner as other posts. FIG. 11 shows a state when the post 3 supported by the corner post 4FR having the retractable portion 16 is folded.

FIG. 12 shows a state in which the retractable portion 16 of the corner post 4FR is further folded inward. The manner in which the retractable portion 16 is vertically moved and rotated when folded is as described above.
The retractable portion 16 originally has a U-shape so as to surround the post 3, and therefore when folded, as shown in FIG. 12, it surrounds the post 3 in the same manner as when standing upright. be able to. That is, the foldable portion 16 can be folded so as to overlap the folded post 3. For this reason, when the foldable portion 16 is folded, the foldable portion 16 does not protrude greatly above the pallet 2 (or the post 3), so that it is hardly disturbed when loading and unloading. . Furthermore, the retractable portion 16 having a sufficient length can be secured according to the length of the post 3 and the necessity of protection thereof. Even the long retractable portion 16 can be overlapped with the post 3 in the height direction, so that it does not disturb the work when folded. Further, even in a narrow space (for example, the same width as the post pallet), the foldable portion 16 can be rotated and folded.

  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.

  On the other hand, as shown in FIGS. 22 and 23, in the conventional product in which the upper part of the corner post is tilted outward, when it is tilted outward, the portion that engages with the lower part of the corner post protrudes from the height position of the pallet, It will lead to damage to corner pillars and reduced work efficiency. Furthermore, if the upper part of the corner pillar that is tilted outwards is lengthened as necessary, depending on the length, when it is tilted outwards, it cannot be fully collapsed until it becomes perpendicular to the ground, and it will fall in a slanted state. . That is, it takes up a large space in the horizontal direction, obstructs the work, and is liable to be damaged by contact. On the other hand, if the bottom of the corner pillar is lengthened, even if the top of the corner pillar can be tilted vertically, the height of the bottom of the corner pillar naturally increases, and the corner pillar is damaged and the work efficiency decreases. Leads to. Further, in a narrow space, the corner column upper part cannot be turned down by rotating outward in the first place.

Furthermore, in the conventional product, the upper and lower corner pillars are engaged with each other, but there are many small parts such as hinges, pins, pin-cylinders, chains, etc., which are easily lost, and the possibility of breakage increases.
However, in the case of the post pallet 1 of the present invention, when the retractable portion 16 is engaged with the leg portion 17, the retractable portion receiver 31 (the bottom surface support plate 32 and the side surface support plate 33) can be used if necessary. Only the cover 36 for adjusting the thickness below the fall part 16 is sufficient, and since it is fixed by welding, it will not be lost. In this respect, it is difficult for damage to occur, and as a result, cost can be reduced.

  As described above, the case where only the right corner post 4FR has the retractable portion 16 has been described here, but in the present invention, only the left corner post 4FL only has the retractable portion. It can have. Furthermore, both the left and right corner pillars 4FR, 4FL can each have a retractable part.

In particular, when both the left and right corner pillars 4FR and 4FL on the front side have a retractable part, the left and right posts 3 and the retractable part 16 are placed inward during work such as loading and unloading. Since it can be folded, there is no obstacle on both the left and right sides, and the work can be performed very efficiently. FIG. 19 shows an example of a state in which both the left and right posts on the front side and the foldable part are folded. As shown in FIG. 19, if all the posts on the front side and the foldable part of the corner post are folded, it is naturally easy to take in and out the luggage from both the left and right sides, and also from the front side.
Moreover, since the retractable part is tilted inward, there is nothing that obstructs the work outside the post pallet 1 on both the left and right sides.

  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. Further, as shown in FIG. 19, similarly, the cushioning material 7 should be made high even when the corner posts 4FL and 4FR are folded inward.

Further, a locking mechanism can be provided in the posts 3RL and 3RR on the rear surface side.
FIG. 13 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 22 is formed on the side surface of the corner post 4RL so that the post fixing pin 21 can be inserted by sliding in the horizontal direction. When the post 3RL stands upright and is fixed to the corner post 4RL, this difference The post fixing pin 21 is inserted into the insertion port 22 and the post fixing pin 21 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. 14 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. 15 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.

FIG. 16 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. 16, 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. 17 shows a state where the right side board mechanism 5 'is folded. FIG. 17 shows a case where the post pallet 1 is viewed from the front side.

  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.

Note that another example of the sideboard mechanism is shown in FIG. First, FIG. 27A is a plan view showing an outline of the sideboard mechanism 5 ″.
As shown in FIG. 27A, the rail 25 and the rail 25 are mainly formed on the side board 24 and the pallet 2 that support the side surface of the load from the lateral direction and extend in the lateral direction (left and right direction) of the post pallet 1. The enclosure is constituted by a connecting member 40 directly attached to the side board 24.

FIG. 27B shows a cross-sectional view of the rail 25 and the connecting member 40 when viewed from the arrow A ′ in FIG.
The connecting member can be made of one member, or, for example, as shown in FIG. 27B, it can be made of a plurality of members (upper connecting member 41, lower connecting member 42). You can also In the example shown in FIG. 27, the connecting member is configured by connecting the connecting upper member 41 and the connecting lower member 42 so as to surround the rail 25 with bolts and nuts. The end of the connecting upper member 41 is attached to the side board 24.
Even with such a structure, the side board 24 can be slid along the rail 25. In addition, the mechanism for fixing the sideboard can be the same as the example shown in FIG.

  The pallet 2, the post 3, the corner post 4, and the side board mechanisms 5, 5 'described above in detail 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 the loss of the parts can be effectively prevented.

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 plurality of glass substrates are stacked to form a block shape 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 3FR on the front side is folded inward, and the folding part 16 of the corner post 4FR is folded on the post 3FR folded inward. 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.
Further, the folding part 16 of the right corner post 4FR on the front side which has been folded first is raised and engaged with the leg part 17 to be fixed. 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.

  In addition, a case will be described in which the front and rear corner posts 4FL and 4FR are folded to carry out the loading / unloading operation. For example, first, the right side post 3FR and the left side post 3FL on the front side are folded inward and overlapped with each other. Furthermore, the foldable part 16 of the right corner post 4FR is folded on the post 3FR folded inward, and the foldable part of the left corner post 4FL is folded on the post 3FL folded inward. The other post 3 on the rear side is fixed in an upright state, and for the right sideboard mechanism 5 ′, by sliding the rail receiver 26 to the rightmost side of the movable range of the rail 25 in the same manner as described above, For the left sideboard mechanism 5, the sideboard 24 is separated from the pallet 2 by sliding the rail receiver 26 to the leftmost side of the movable range of the rail 25.

In this way, preparations are made so as to facilitate loading / unloading of the luggage from the entire front surface or from both the left and right sides, and the luggage is placed on the pallet 2.
Thereafter, the sideboards 24 of the left and right sideboard mechanisms 5, 5 ′ are fixed at appropriate positions to support the side surfaces of the luggage. Further, the folding parts 16 of the left and right corner pillars 4FL and 4FR on the front side which were folded first are raised and engaged with the leg part 17 to be fixed, and further the posts 3FL and 3FR are raised, and the lower ends are respectively set at the corners. Insert and fix to pillars 4FL, 4FR and erect.
In the same manner as described above, the post pallet 1 can be transported with 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, and 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.

An example of the state which piled up post pallets 1 is shown in FIG.
The lower end of the corner post of the post pallet has a downward-facing hook shape, and the upper end of the corner post of another post pallet can be fitted into the hook shape. That is, the upper end of the corner post of the lower post pallet is inserted into the lower end of the corner post of the upper post pallet so as to be stably stacked.

  At this time, if the upper end of the corner pillar is marked with, for example, paint, whether or not the corner pillar is standing so that it can be stacked (when the folding part is supported by the leg) You can see at a glance. Furthermore, if the marks are marked so that they are hidden in the bowl shape at the bottom of the corner pillar when accurately and stably stacked, it is easy to check whether they are correctly stacked at a glance. Can be made more safe.

  The present invention is not limited to the above embodiment. The above-described embodiment is an exemplification, and the present invention has substantially the same configuration as the technical idea described in the claims of the present invention, and any device that exhibits the same function and effect is the present invention. It is included in the technical scope of the invention.
