Description

The present invention relates to a tray for placing articles on which articles are placed. More specifically, the present invention relates to a tray for placing articles, which can form an annular tray combination as a whole by arranging a plurality of trays in an annular shape. The present invention also covers tray conjugates formed cyclically by a plurality of tray conjugates.

As a conventional article placing tool, the packing system described in Patent Document 1 can be mentioned. The packing system described in FIG. 1 of the same document is composed of a “pallet P”, a “sleeve S”, and a “lid / intermediate tray T”. The "sleeve S" has a square tube shape as a whole, and also has a "partition member 11" inside, and is divided into a plurality of rooms. By placing this "sleeve S" on the "pallet P", it is possible to store articles in each room of the "sleeve S". Therefore, the "pallet P" is formed with a "peripheral groove 6" and a "groove 7" for accommodating the lower end of the "sleeve S". The "lid and intermediate tray T" covers the upper end of the "sleeve S" and also functions as an intermediate member for multi-tiered stacking.

Japanese Unexamined Patent Publication No. 2004-42932

However, in the above-mentioned conventional technique, it is necessary to use the "pallet P" in which the "peripheral groove 6" and the "groove 7" are formed as described above. Such a "pallet P" is not a general-purpose product, but a dedicated product for the packaging system of Patent Document 1. In other words, it was not possible to use the pallets that are generally provided as general-purpose products. Further, in order to place a plurality of articles, it is necessary to provide the "sleeve S" with the "partition member 11". Therefore, the structure of the "sleeve S" is complicated, and its productivity is low.

The present invention has been made to solve the problems of the above-mentioned conventional techniques. That is, the problem is to provide an article loading tray that can be configured to be able to mount a plurality of articles with a simple configuration without the need for a special pallet or a sleeve having a complicated structure. In addition, a tray combination in which a plurality of trays for placing articles are combined is also provided.

In one aspect of the present invention, a plurality of trays for placing articles are arranged in an annular shape to form a tray joint as a whole, and the overall shape when viewed from above is the outer edge of the tray joint. The outward side that forms a part of the above, the first inward side that is located next to one of the outward sides without forming a part of the outer side of the tray joint, and a part of the outer side of the tray joint Instead, it is located next to the other side of the outward side, and has a second inward side that is connected to the first inward side of another tray for placing articles when the tray joint is constructed. There is, on the first inward facing side, a first coupling shape portion for being coupled with the second inward facing side of another article placing tray is formed, and on the second inward facing side, another A second joint shape portion for being bonded to the first inward side of the article placing tray is formed.

In the tray for placing articles in the above aspect, the articles can be placed independently, but a plurality of articles can be placed by forming a tray combination. In the state where the tray joint is formed, each tray for placing articles is arranged in a rotationally symmetric shape (windmill shape) to form an annular shape as a whole. Then, the first inward facing side of a certain article loading tray and the second inward facing side of the adjacent article loading tray face each other, and the tray combination is formed by the set of the outward facing sides of each article loading tray. The outer edge of is composed. At the portion where the first inward facing side and the second inward facing side face each other, the first coupling shape portion and the second coupling shape portion are connected. As a result, the whole is integrated to form a tray joint. A pallet can be attached under this tray combination, but in that case, the pallet may be a general-purpose product.

The article mounting tray of the above embodiment also, along the outward sides, that are the sidewall retention feature portion can be inserted a plate-like member is open from the upper upward is formed. In this way, in the state where the tray joint is assembled, the side wall holding shape portion can be used to hold the side wall member that surrounds the entire tray joint. The wall-shaped member may be a simple tubular or square tubular member and does not require an internal partition.

In the article loading tray of the above aspect, the outward side is composed of adjacent non-parallel first outward side and second outward side, and the first inward side is the first outward side. It is desirable that the second inward side is located next to the second outward side. If this is the case, the overall shape of the article placing tray when viewed from above becomes a polygon (for example, a rectangle). The overall shape of the tray joint is also polygonal (for example, square), making it easy to use.

Further, in the tray for placing articles in any of the above embodiments, a holding surface for receiving the inserted plate-shaped member is formed in the side wall holding shape portion, and the outward side is partially more than the holding surface. It is desirable that a bottom portion recessed downward is formed, and a third joint shape portion for connecting to the lower member is formed on the bottom portion. If this is the case, the fastener material will hold the side wall member even when the article placing tray is connected to the lower member by some fastening member using the third coupling shape portion. Do not disturb.

In the article loading tray of any of the above aspects, the first coupling stage is formed in the first coupling shape portion, and the second coupling shape portion is projected outward. Two binding stages are formed, the first binding stage and the second binding stage are formed at different height levels, and are formed at the higher level of the first binding stage and the second binding stage. On the lower surface side of the object and on the upper surface side of the object formed at the lower level, recesses for accommodating the first coupling stage or the second coupling stage of other article loading trays when the tray coupling is formed. Are formed, and holes are formed in the first coupling stage and the second coupling stage at positions corresponding to each other when they are overlapped with the second coupling stage or the first coupling stage of another article loading tray. It is desirable that it is open.

If this is done, the tray combination can be constructed by all the same type of trays for placing articles. At any of the article loading trays facing each other, one of the first binding stage and the second binding stage is formed at the lower level and one is formed at the higher level. This is because they will be overlapped. Therefore, in manufacturing, it is not necessary to make different types of trays for placing articles. Also, in terms of use, it is not necessary to manage and use multiple types of trays for placing articles.

It is also desirable that the tray for placing articles in any of the above embodiments has a support shape portion for supporting the articles to be placed on the upper surface side. This is because if this is the case, the placed article will be stable in the shape of a tray for placing the article.

The tray coupling according to another aspect of the present invention has a plurality of trays for loading articles in any one of the above aspects, and has a first coupling shape portion of a tray for loading articles and other articles. The whole is formed in an annular shape by being bonded to the second coupling shape portion of the tray. As described above, such a tray combination is a general-purpose product and does not require a special product even when a pallet is used.

According to this configuration, there is provided an article loading tray that can be configured to be able to mount a plurality of articles with a simple configuration without the need for a special pallet or a sleeve having a complicated structure. In addition, a tray combination in which a plurality of trays for placing articles are combined is also provided.

Hereinafter, embodiments embodying the present invention will be described in detail with reference to the accompanying drawings. This embodiment embodies the present invention as a tray for placing articles (hereinafter, simply referred to as “tray”) 1 shown in FIGS. 1 to 4. The tray 1 has an overall rectangular shape when viewed from above (see FIG. 4). The tray 1 has a first long side portion 2, a second long side portion 3, a first short side portion 4, and a second short side portion 5. Further, an opening 8 is formed in the central portion of the tray 1. In the tray 1, what is visible in FIGS. 1, 2 and 4 is the upward surface for placing the article, and what is visible in FIG. 3 is the back surface. In the tray 1, ridge-shaped article support shape portions 9 and 10 are further formed on the first short side portion 4 and the second short side portion 5.

The tray 1 is for placing four articles in one group by forming a tray combination of four pieces. FIG. 5 shows a situation in which four articles are placed on the tray joint 13 formed by the pallet 12 and the four trays 1. These four trays 1 are all the same. FIG. 5 shows a situation in which a steel wire winding bobbin 14 is placed on each tray 1 as a mounted article. The four steel wire winding bobbins 14 in FIG. 5 are arranged so as to form a rotational symmetry (windmill shape) when viewed from above by changing the direction by 90 °.

FIG. 6 shows a plan view of the tray coupling 13 excluding the four steel wire winding bobbins 14 from the state of FIG. As is clear from FIG. 6, the four trays 1 in the tray coupling 13 are also arranged to form a rotational symmetry (windmill shape) like the four steel wire winding bobbins 14 in FIG. .. In FIG. 6, the surface of the pallet 12 is seen at the opening 8 in each tray 1 and the gap 15 in the center of the four trays 1.

As shown in FIG. 7, the tray coupling 13 and the four steel wire winding bobbins 14 in the state shown in FIG. 5 can be covered with the upper box body 20. In FIG. 7, the upper box body 20 is shown by a chain double-dashed line. The upper box body 20 is composed of a square tube member 21 and a lid member 22. The square tubular member 21 is a square tubular member in which four plate-shaped wall members standing on the edge of the tray coupling 13 are integrally provided. The square tube member 21 does not have a portion corresponding to the “partition member 11”. The lid member 22 is a member that closes the opening at the upper end of the square tube member 21. Hereinafter, the tray coupling body 13, the four steel wire winding bobbins 14, and the upper box body 20 as a whole are referred to as a packing body 23. As shown in FIG. 8, the packing bodies 23 can be stacked in multiple stages.

Further, as shown in FIG. 9, the tray coupling 16 can be assembled with only four trays 1 without using the pallet 12. That is, the tray coupling 16 of FIG. 9 is obtained by removing the pallet 12 from the tray coupling 13 of FIG. Four steel wire winding bobbins 14 can also be placed on the tray coupling 16 of FIG. Further, the tray coupling body 16 can be covered with the upper box body 20. The tray joint 16 of FIG. 9 has a square shape as a whole. In each tray 1 of the tray coupling 16 of FIG. 9, the first long side portion 2 and the first short side portion 4 face the outer side of the tray coupling 16. On the other hand, the second long side portion 3 and the second short side portion 5 do not face the outer side as the tray coupling 16.

Hereinafter, each tray 1 will be further described. As shown in FIG. 1, a side wall holding shape portion 19 is formed on the first long side portion 2 and the first short side portion 4 of the tray 1 along the edge edges 17 and 18. The edges 17 and 18 are outward sides that form a part of the outer side of the tray coupling 16. The side wall holding shape portion 19 has a groove shape that opens upward, and is a portion for inserting the lower end of the square tube member 21 described above. Therefore, the side wall holding shape portion 19 is bottomed. That is, the side wall holding shape portion 19 is formed with a holding surface 24 facing upward. The holding surface 24 receives the lower end of the square tube member 21.

The edges 17 and 18 of the tray 1 are further partially formed with a bottom portion 25 recessed below the holding surface 24. Further, a hole 26 is formed in the bottom portion 25. The hole 26 has a shape for connecting the tray 1 to the above-mentioned pallet 12. In the tray 1 of this embodiment, holes 26 are formed at four locations in total, two at each of the edges 17 and 18. Using the holes 26, the tray 1 can be connected to the pallet 12 by means such as bolting. Even in that case, the head of the bolt does not interfere with the lower end of the square tube member 21. This is because the hole 26 is formed in the bottom portion 25 which is lower than the holding surface 24.

On the other hand, the second long side portion 3 and the second short side portion 5 of the tray 1 have a structure different from the above-described structures of the first long side portion 2 and the first short side portion 4. Horizontal first coupling stages 27 and second coupling stages 28 are formed on the second long side portion 3 and the second short side portion 5 (see FIG. 2). The first coupling stage 27 and the second coupling stage 28 are partially formed with respect to the edges 29 and 30 of the second long side portion 3 and the second short side portion 5, and have a shape that protrudes outward. .. However, the first coupling stage 27 and the second coupling stage 28 do not protrude outward in the tray coupling 16 of FIG. This is because the edges 29 and 30 are inward sides that do not form a part of the outer side of the tray coupling 16. When the whole of the edges 17 and 18 is regarded as the outward side, the edge 29 is the side located next to one of the outward sides, and the edge 30 is the side located next to the other outward side. Is.

The first binding stage 27 and the second binding stage 28 are shapes for binding the adjacent trays 1 to each other in the tray coupling body 16. That is, the first coupling stage 27 and the second coupling stage 28 are overlapped at the four abutting points of the trays 1 in the tray coupling 16 of FIG.

As you can see from a closer look at FIG. 2, the second coupling stage 28 is formed closer to the lower end in the height direction dimension of the tray 1 as a whole, whereas the first coupling stage 27 is formed. It is formed at a height level that floats above. For this reason, the first coupling stage 27 is located on the upper side and the second coupling stage 28 is located below the first coupling stage 27 in all of the above-mentioned four abutting portions. Therefore, a recess 31 is formed on the upper side of the second coupling stage 28 (see FIG. 2). The recess 31 is, of course, a space for accommodating the first coupling stage 27 of the adjacent tray 1. On the other hand, a recess 32 is similarly formed on the lower side of the first coupling stage 27 (see FIG. 3). The recess 32 is, of course, a space for accommodating the second coupling stage 28 of the adjacent tray 1.

Holes 33 are formed in the first coupling stage 27 and the second coupling stage 28, respectively. The holes 33 are provided at positions where the trays 1 overlap each other when the first coupling stage 27 and the second coupling stage 28 are overlapped with each other. In the tray 1 of this embodiment, two holes 33 are formed in each of the first coupling stage 27 and the second coupling stage 28. Using the holes 33, the first coupling stage 27 and the second coupling stage 28 of the trays 1 can be coupled to each other by means such as bolting. It is also possible to connect to the pallet 12 with the same bolt.

FIG. 10 shows a perspective view of a situation in which the tray coupling 13 is being assembled using the pallet 12. FIG. 10 shows a situation in which the first tray 1 is arranged above the pallet 12. In this situation, there is a gap between the pallet 12 and the tray 1. From this situation, the tray 1 is lowered and placed on the surface of the pallet 12. At that time, the angle formed by the edges 17 and 18 of the tray 1 is made to coincide with the angle of the pallet 12. Then, the tray 1 is placed in order according to the corners of the pallet 12. Then, for example, the tray 1 is fixed to the pallet 12 by the bolt 34 and the nut 35.

Here, if the bolts are tightened every time one tray 1 is placed on the pallet 12, it is difficult to place the last fourth tray 1. This is because it is difficult to correctly superimpose both the first coupling stage 27 and the second coupling stage 28 between the last tray 1 and the adjacent trays 1. For this reason, it is better to tighten the tray loosely at the beginning, place the last tray 1 correctly, and then retighten it.

When the tray coupling 13 is formed in this way, the side wall holding shape portions 19 of the four trays 1 form a square shape as a whole. The square is slightly smaller than the square when the pallet 12 is viewed from above. The lower part of the square tube member 21 is inserted into the square side wall holding shape portion 19.

Subsequently, the situation between the members in the state of the package 23 will be described with reference to the cross-sectional views of FIGS. 11 to 13. Each of these cross-sectional views depicts the height range around the tray 1 and the pallet 12 in the packing body 23. Within this range, the lower part of the steel wire winding bobbin 14 and the square tube member 21 also appears. The cross-sectional positions drawn are the AA position (FIG. 11), the BB position (FIG. 12), and the CC position (FIG. 13) in FIG. The line of sight is the arrow F in FIG.

In any of FIGS. 11 to 13, a situation appears in which the steel wire winding bobbin 14 is stably supported by the article support shape portions 9 and 10. In FIG. 13, the inside of the article support shape portions 9 and 10 is solid, and the cross-sectional position in FIG. 13 is the position of the internal rib 36 (see FIG. 3) of the article support shape portions 9 and 10. Because it matched with.

Of these three cross-sectional views, FIGS. 12 and 13 show a situation in which the lower end of the square tube member 21 is received by the holding surface 24 of the side wall holding shape portion 19 (near the left end in the drawing). However, this situation does not appear in FIG. This is because the cross-sectional position of FIG. 11 is the position where the above-mentioned bottom portion 25 is formed. A bolt 34 and a nut 35 appear at the relevant location in FIG. In this method, the bottom 25 of the tray 1 is fixed to the pallet 12. Here, since the bottom portion 25 is lower than the holding surface 24 as described above, the head of the bolt 34 does not interfere with the square tube member 21.

On the other hand, FIG. 13 shows the state of the joints between the trays 1 (the part on the right side of the figure). That is, at that location, the first coupling stage 27 and the second coupling stage 28 are overlapped. The first coupling stage 27 at the relevant location is for the tray 1 on the right side in the drawing, and the second coupling stage 28 is for the tray 1 on the left side in the drawing. The portion is fastened with a bolt 34 and a nut 35. At that location, the pallet 12 is also fixed.

Next, a modified example of this embodiment will be described with reference to FIGS. 14 to 16. The tray 41 according to this modification has a substantially square shape as a whole when viewed from above (FIG. 15). In the tray 41, side wall holding shape portions 19 are formed on the right side and the lower side in FIG. Of course, a holding surface 24, a bottom 25, and a hole 26 are also formed there. Therefore, in the tray 41, the right side and the lower side in FIG. 15 are outward sides. On the other hand, the side wall holding shape portion 19 is not formed on the left side and the upper side in FIG. 15 of the tray 41. Instead, a first coupling stage 27 is provided on the left side and a second coupling stage 28 is provided on the upper side. A hole 33 is also formed. Therefore, in the tray 41, the left side and the upper side in FIG. 15 are inward facing sides.

Therefore, in the tray coupling 46 (FIG. 16) in which the four trays 41 are joined, the right side and the lower side in FIG. 15 of each tray 41 form the outer side as a whole. The tray 41 is not provided with a portion having the same shape as the article support shape portions 9 and 10 in the tray 1 described above. Instead, the tray 41 is formed with a bank-shaped dam 49 just inside the four sides. In the tray 41, the dam portion 49 is a portion shaped to support the mounted article. Further, unlike the tray 1 described above, the tray 41 does not have an opening 8. Instead, the tray 41 has a bottom surface 42 as a whole inside the dam portion 49. However, this point is arbitrary, and the tray 41 may be provided with the opening 8, or the tray 1 may not have the opening 8.

As described in detail above, according to the tray 1 according to the present embodiment, the first long side portion 2 and the first long side portion 2 whose overall shape when viewed from above forms a part of the outer side of the tray joints 13 and 16. It has a shape having a first short side portion 4, a second long side portion 3 and a second short side portion 5 which do not form an outer side of the tray couplings 13 and 16. Then, on the second long side portion 3 and the second short side portion 5, a first coupling stage 27, which is the upper side of the superposition when the tray couplings 13 and 16 are coupled, and a second coupling stage 28, which is the lower side, are provided. It is provided. As a result, a tray for placing a plurality of articles can be realized by forming the tray joints 13 and 16 without the need for a special pallet.

Further, by providing the side wall holding shape portions 19 on the first long side portion 2 and the first short side portion 4, the tray couplings 13 and 16 are packed by using the square tube member 21 having a simple structure. The body 23 can be constructed. The same applies to the tray 41 according to the modified example. Further, tray coupling bodies 13, 16 and 46 in which a plurality of trays 1, 41 are combined have been realized.

It should be noted that the present embodiment is merely an example and does not limit the present invention in any way. Therefore, as a matter of course, the present invention can be improved and modified in various ways without departing from the gist of the present invention. For example, the bobbin 14 for winding a steel wire has been exemplified as a mounted article, but the present invention is not limited to this. It may be a bobbin that winds up a wire other than a steel wire, or it may not be a bobbin in the first place. The shape portion that supports the mounted article is not limited to the shape shown as the article support shape portions 9 and 10 or the dam portion 49. Any shape may be used according to the shape of the article to be placed. Depending on the shape of the article to be placed, a part that can be said to be a shape for supporting the article may not be required. Further, when the opening 8 is formed, it is not essential that the whole is a quadrangular ring shape. That is, in the tray 1, either one of the first long side portion 2 and the second long side portion 3 may be interrupted.

Further, in the trays 1 and 41, the side wall holding shape portion 19 to the holding surface 24 is provided over the entire outer side of the tray couplings 13, 16 and 46. However, this is also not essential, and the side wall holding shape portion 19 or the holding surface 24 may be formed only on a part of the outer side. In short, it is sufficient that the square tube member 21 can be stably held in the state where the tray couplings 13, 16 and 46 are assembled. Further, it is not essential that the bottom portion 25 is recessed below the holding surface 24. This is because even if the head of the bolt 34 protrudes upward from the holding surface 24, it is not always possible to stably hold the square tube member 21. For example, a recess for avoiding the head of the bolt 34 may be provided at the lower end of the square tube member 21.

Further, in the above description, it is assumed that the square tube member 21 and the lid member 22 are separate bodies as the upper box body 20, but they may be integrated. On the contrary, the square tube member 21 may be further divided into a plurality of pieces. For example, the shape may be separated into two at one corner and the diagonal position thereof, or may be separated into two at the middle of one side and the middle of the opposite side. It is conceivable to separate the three-sided member and the one-sided member at the positions of one corner and the corner adjacent to it, but in that case, it is better to integrate the one-sided member with the lid member 22. Further, the lid member 22 may not be used and only the square tube member 21 may be used. Further, considering the case where the article is used for the purpose of decorative display, the upper box body 20 may not be used. In that case, the side wall holding shape portion 19 and the holding surface 24 are unnecessary.

Further, in the above description, the trays 1 and 41 are provided with the first coupling stage 27 and the second coupling stage 28 one by one, but this is also not essential. Two each having the first coupling stage 27 at two locations and not having the second coupling stage 28 and two having the second coupling stage 28 at two locations and not having the first coupling stage 27 are combined. It is also possible to form a tray joint with four pieces. However, in that case, it is disadvantageous in that it is necessary to make two types of trays separately and to use them properly when using them. Further, the shapes of the first coupling stage 27 and the second coupling stage 28 themselves are also arbitrary. In short, the shape may be such that the inward facing sides of the tray 1 and the inward facing sides of the tray 41 can be connected to each other. The shape of the bottom 25 on the outward side may be any shape that can be connected to the pallet 12.

Further, when the overall shape is rectangular as in the tray 1, the position of the tray 1 in the tray joints 13 and 16 can be changed. That is, when looking at FIG. 6, each tray 1 is arranged so as to match the apex of the pallet 12. As a result, the second short side portion 5 of each tray 1 faces the outermost position of the second long side portion 3 of the adjacent tray 1. This may be changed so that the portion of the pallet 12 near the outer edge is slightly exposed. That is, the second short side portion 5 of each tray 1 may face the innermost position or the intermediate position of the second long side portion 3 of the adjacent tray 1. This is a little disadvantageous in terms of space efficiency, but it is possible to construct a tray bond. In that case, it is sufficient that the side wall holding shape portion 19 and the holding surface 24 are formed only on the outer side portion of the tray coupling as a whole. Further, the portion of the second long side portion 3 that does not face the second short side portion 5 does not have to be linear.

Further, when the overall shape is substantially square like the tray 41, the number of trays 41 for forming the tray coupling is not limited to four. For example, a tray combination can be formed by 6 pieces of 2 rows × 3 columns. In that case, unlike the trays of this embodiment, the two trays in the center row have only one side facing outward and three sides facing inward. However, the four trays 41 at the four corners are within the scope of the present invention. It is also possible to form a tray combination with a larger number of trays.

Moreover, the overall shape of the tray when viewed from above is not limited to a rectangle or a square. For example, the overall shape of each tray may be a parallelogram or a trapezoid, and the overall shape of the tray joint may be a regular polygon (equilateral triangle, regular hexagon, etc.) other than a square. Further, in that case, the side that becomes the outward side does not need to be clearly divided into two sides. The outer side may be arcuate as a whole, and the outer shape of the tray joint as a whole may be circular (however, the number of trays is finite).
