It is the side view which looked at the short side side of from the side. FIG. 3 is a bottom view of the display panel packaging tray 1 of the first embodiment. FIG. 4 is a longitudinal sectional view seen from the line IV-IV in FIG.
　図２～図４は、表示パネル用梱包トレー１が梱包対象物であるオープンセルパネル４０を収容した状態を示している。ここで、オープンセルパネル４０とは、表示パネルの一例としての液晶パネルに、周辺部品の一例としてのＣＯＦ（Chip On Film：チップ・オン・フィルム）やＰＣＢ（Printed Circuit Board：プリント回路基板）などが取り付けられたものである。 FIGS. 2 to 4 show a state in which the display panel packing tray 1 accommodates the open cell panel 40 as the packing object. Here, the open cell panel 40 refers to a liquid crystal panel as an example of a display panel, COF (chip on film: chip on film) as an example of peripheral components, printed circuit board (PCB), etc. Is attached.
　トレー本体１０の収容凹部１０ａには、オープンセルパネル４０が、その表面または裏面（表示パネルの表面または裏面）が底部１１の上面に対向するように収容される。図２に示すように、底部１１の上面に設けられた第１の緩衝材２０の平面形状は、オープンセルパネル４０の平面形状（表示パネルの周辺部品を含む平面形状）よりも大きく設定されている。これにより、オープンセルパネル４０における底部１１の上面に対向する側（下側）の全面が第１の緩衝材２０によって支持される。 The open cell panel 40 is accommodated in the accommodation recess 10 a of the tray main body 10 such that the front surface or the back surface (the front surface or the back surface of the display panel) faces the top surface of the bottom 11. As shown in FIG. 2, the planar shape of the first cushioning material 20 provided on the upper surface of the bottom portion 11 is set larger than the planar shape of the open cell panel 40 (the planar shape including peripheral components of the display panel) There is. Thus, the entire surface of the side (lower side) opposite to the upper surface of the bottom 11 in the open cell panel 40 is supported by the first shock absorbing material 20.
　図３に示すように、トレー本体１０の底部１１の下面には、その外周縁（底部１１の各辺）に沿って下方に向けて突出するリブ１３（突起部）が設けられている。底部１１の下面において、第２の緩衝材３０は、例えばリブ１３に囲まれた全領域に設けられている。図３における一点鎖線は、収容凹部１０ａに収容されたオープンセルパネル４０の外形を示している。すなわち、第２の緩衝材３０の平面形状も、第１の緩衝材２０と同様に、オープンセルパネル４０の平面形状よりも大きく設定されている。これにより、オープンセルパネル４０を収容した表示パネル用梱包トレー１に他の表示パネル用梱包トレー１が積み重ねられたときに、他の表示パネル用梱包トレー１の第２の緩衝材３０によって、オープンセルパネル４０の当該第２の緩衝材３０側（上側）の全面が支持される。 As shown in FIG. 3, the lower surface of the bottom 11 of the tray main body 10 is provided with ribs 13 (projections) projecting downward along the outer peripheral edge (each side of the bottom 11). On the lower surface of the bottom 11, the second cushioning material 30 is provided, for example, in the entire area surrounded by the ribs 13. The dashed-dotted line in FIG. 3 has shown the external shape of the open cell panel 40 accommodated in the accommodation recessed part 10a. That is, the planar shape of the second cushioning material 30 is also set larger than the planar shape of the open cell panel 40 as in the case of the first cushioning material 20. Thus, when another display panel packaging tray 1 is stacked on the display panel packaging tray 1 accommodating the open cell panel 40, the second buffer material 30 of the other display panel packaging tray 1 opens the display panel packaging tray 1. The entire surface of the second shock absorbing material 30 (upper side) of the cell panel 40 is supported.
　図４に示すように、収容凹部１０ａにオープンセルパネル４０が収容された状態で、オープンセルパネル４０の上側の面は、枠体１２の上端部よりも低い位置にある。従って、表示パネル用梱包トレー１は、オープンセルパネル４０を収容凹部１０ａに収容した状態で積み重ねることができる。例えば、オープンセルパネル４０の液晶パネルの厚さは約１．８ｍｍであり、第１の緩衝材２０および第２の緩衝材３０の厚さはそれぞれ約３ｍｍであり、枠体１２の高さ（底部１１の上面から枠体１２の上端部までの距離）は約６ｍｍである。 As shown in FIG. 4, with the open cell panel 40 housed in the housing recess 10 a, the upper surface of the open cell panel 40 is at a lower position than the upper end of the frame 12. Therefore, the display panel packaging tray 1 can be stacked in a state where the open cell panel 40 is accommodated in the accommodation recess 10 a. For example, the thickness of the liquid crystal panel of the open cell panel 40 is about 1.8 mm, the thicknesses of the first buffer 20 and the second buffer 30 are each about 3 mm, and the height of the frame 12 ( The distance from the upper surface of the bottom 11 to the upper end of the frame 12 is about 6 mm.
　図５は、第１実施形態の表示パネル用梱包トレー１が複数積層された梱包トレー積層体１００の斜視図である。図６は、第１実施形態の梱包トレー積層体１００の縦断面図である。なお、図５および図６では、５つの表示パネル用梱包トレー１が積層されているが、積層される表示パネル用梱包トレー１の数は５つに限られず、実際の搬送時には２０～３０個の表示パネル用梱包トレー１が積層されて梱包トレー積層体１００が構成される。 FIG. 5 is a perspective view of a packaging tray stack 100 in which a plurality of display panel packaging trays 1 according to the first embodiment are stacked. FIG. 6 is a longitudinal sectional view of the packing tray laminate 100 of the first embodiment. In FIGS. 5 and 6, although five display panel packing trays 1 are stacked, the number of display panel packing trays 1 to be stacked is not limited to five, and 20 to 30 in actual transportation. The display panel packing trays 1 are stacked to form a packing tray laminate 100.
　図６に示すように、梱包トレー積層体１００を構成する複数の表示パネル用梱包トレー１のうち、最も上側の表示パネル用梱包トレー１を除く１以上（図６の例では４つ）の表示パネル用梱包トレー１のそれぞれにオープンセルパネル４０が収容されている。そして、梱包トレー積層体１００において、収容された各オープンセルパネル４０は、その下側の面が、当該オープンセルパネル４０を収容する表示パネル用梱包トレー１の第１の緩衝材２０によって支持され、その上側の面が、当該オープンセルパネル４０を収容する表示パネル用梱包トレー１の上に積み重ねられた表示パネル用梱包トレー１（一段上の表示パネル用梱包トレー１）の第２の緩衝材３０によって支持されている。すなわち、梱包トレー積層体１００において、収容された各オープンセルパネル４０は、当該オープンセルパネル４０を収容する表示パネル用梱包トレー１の第１の緩衝材２０と、一段上の表示パネル用梱包トレー１の第２の緩衝材３０とによって挟持されている。 As shown in FIG. 6, among the plurality of display panel packaging trays 1 constituting the packaging tray stack 100, display of one or more (four in the example of FIG. 6) excluding the uppermost display panel packaging tray 1 An open cell panel 40 is accommodated in each of the panel packaging trays 1. Then, in the packing tray laminate 100, the lower surface of each open cell panel 40 accommodated is supported by the first buffer material 20 of the display panel packing tray 1 in which the open cell panel 40 is accommodated. , The second buffer material of the display panel packing tray 1 (display panel packing tray 1 on the upper level) stacked on the display panel packing tray 1, the upper surface of which is housed in the open cell panel 40 Supported by 30. That is, in the packing tray laminate 100, each open cell panel 40 received is the first buffer material 20 of the display panel packing tray 1 for housing the open cell panel 40, and the display panel packing tray one step higher It is clamped by the 1st 2nd shock absorbing material 30. FIG.
　上記構成によれば、オープンセルパネル４０が収容された複数の表示パネル用梱包トレー１が積み重ねられた状態で、各オープンセルパネル４０が第１の緩衝材２０と第２の緩衝材３０とによって挟持される。つまり、各オープンセルパネル４０が２つの緩衝材によってパネル面で保持される。これによって、複数のオープンセルパネル４０を積層して運搬するときに大きな衝撃を受けても、各オープンセルパネル４０のパネル面全体に荷重が分散されるので、パネル欠けを防止できる。 According to the above configuration, each of the open cell panels 40 is formed of the first shock absorbing material 20 and the second shock absorbing material 30 in a state where the plurality of display panel packaging trays 1 accommodating the open cell panels 40 are stacked. It is pinched. That is, each open cell panel 40 is held on the panel surface by two cushioning materials. As a result, even if a large impact is received when stacking and transporting the plurality of open cell panels 40, the load is distributed to the entire panel surface of each open cell panel 40, so that it is possible to prevent the panel chipping.
　また、オープンセルパネル４０が収容された複数の表示パネル用梱包トレー１が積み重ねられた状態で、表示パネル用梱包トレー１に設けられたリブ１３は、当該表示パネル用梱包トレー１の一段下の表示パネル用梱包トレー１の枠体１２の内側に嵌まり込む。これによって、表示パネル用梱包トレー１の横方向への移動が規制される。なお、積み重ねられた複数の表示パネル用梱包トレー１をまとめて例えば結束バンドなどを用いて締結することにより、或いは後述する連結構造を用いることにより、表示パネル用梱包トレー１の上下方向の移動を規制することができる。このように、実施形態の構成によれば、簡易な構成で、積み重ねられた状態を確実に保持したまま梱包トレー積層体１００を運搬することができる。 Further, in a state in which the plurality of display panel packaging trays 1 accommodating the open cell panels 40 are stacked, the rib 13 provided on the display panel packaging tray 1 is one step below the display panel packaging tray 1. It fits inside the frame 12 of the display panel packaging tray 1. As a result, the movement of the display panel packing tray 1 in the lateral direction is restricted. The vertical movement of the display panel packing tray 1 can be achieved by collectively holding the plurality of display panel packing trays 1 stacked and fastening them using, for example, a binding band, or by using a connection structure described later. It can be regulated. As described above, according to the configuration of the embodiment, the packing tray stack 100 can be transported with a simple configuration while keeping the stacked state securely.
　さらに、第１実施形態の構成によれば、以下のような効果が得られる。まず、リブ１３が枠体１２の側方に出っ張らないので、梱包トレー積層体１００の外形の側面が平坦になり扱いやすくなる。 Furthermore, according to the configuration of the first embodiment, the following effects can be obtained. First, since the rib 13 does not protrude to the side of the frame 12, the side of the outer shape of the packing tray laminate 100 is flat and easy to handle.
　また、梱包トレー積層体１００として運搬することでオープンセルパネル４０のパネル欠けを防ぐことができるので、別途梱包箱を使用する必要がない。 Moreover, since it can prevent the panel chipping of the open cell panel 40 by conveying as the packaging tray laminated body 100, it is not necessary to use a packaging box separately.
　また、低反発素材からなる保護シートを第１の緩衝材２０および第２の緩衝材３０に用いることによって、オープンセルパネル４０を構成する液晶パネルの厚さよりも基板コネクタなどが高くなっても、オープンセルパネル４０における基板コネクタなどによる凸凹を吸収して、２つの第１,第２の緩衝材２０,３０によってオープンセルパネル４０をパネル面で保持することができ、オープンセルパネル４０の基板コネクタなどの高さの制限を緩和することができる。 Further, by using a protective sheet made of a low resilience material as the first shock absorbing material 20 and the second shock absorbing material 30, even if the substrate connector or the like becomes higher than the thickness of the liquid crystal panel constituting the open cell panel 40, The open cell panel 40 can be held on the panel surface by the two first and second buffer members 20 and 30 by absorbing unevenness due to a substrate connector or the like in the open cell panel 40, and the substrate connector of the open cell panel 40 You can relax height restrictions such as.
　また、表示パネル用梱包トレー１にオープンセルパネル４０を収容する際にオープンセルパネル４０を位置決めする必要がないので、表示パネル用梱包トレー１は、サイズの異なる複数種類のオープンセルパネル４０を収容することができる。従って、サイズの異なる複数種類のオープンセルパネル４０に対して同一仕様の表示パネル用梱包トレー１を共通に使用することができる。ここで、第１の緩衝材２０および第２の緩衝材３０それぞれの平面形状は、複数種類のオープンセルパネル４０のうちサイズの最も大きいオープンセルパネル４０の平面形状よりも大きい。 Further, since it is not necessary to position the open cell panel 40 when the open cell panel 40 is accommodated in the display panel packing tray 1, the display panel packing tray 1 accommodates a plurality of different open cell panels 40 of different sizes. can do. Therefore, the display panel packaging tray 1 having the same specification can be commonly used for a plurality of types of open cell panels 40 having different sizes. Here, the planar shape of each of the first shock absorbing material 20 and the second shock absorbing material 30 is larger than the planar shape of the largest open cell panel 40 among the plurality of types of open cell panels 40.
　なお、第１実施形態では、トレー本体１０の底部１１の４つの辺のそれぞれに沿ってリブ１３を設けたが、４つの辺のうちの何れかの辺にだけリブ１３を設けてもよいし、底部１１の辺の全域ではなく辺の一部にリブ１３を設けてもよい。また、第１実施形態では、１つの表示パネル用梱包トレー１に１つのオープンセルパネル４０が収容されたが、１つの表示パネル用梱包トレー１に複数のオープンセルパネル４０が収容されてもよい。 In the first embodiment, the ribs 13 are provided along each of the four sides of the bottom portion 11 of the tray main body 10, but the ribs 13 may be provided only on any of the four sides. The ribs 13 may be provided not on the entire area of the side of the bottom 11 but on part of the side. In the first embodiment, one open cell panel 40 is accommodated in one display panel packing tray 1, but a plurality of open cell panels 40 may be accommodated in one display panel packing tray 1. .
