Description
- 1. Field of the Invention
- The present invention relates to a transport tray, and a transporting package and a transporting method using the same. More particularly, the present invention relates to a transport tray capable of alternately transporting two articles whose shapes and thickness are different from each other, and a transporting package using the tray, and a transporting method using the tray.
- 2. Description of the Related Art
- Recently, it has been becoming popular for companies to assemble liquid crystal modules (which will be abbreviated as “LC modules” hereinafter) by utilizing so-called EMS (Electronics Manufacturing Service), i.e., by entrusting a factory other than the companies' factories with the assembling operation. In many cases, as shown in
FIG. 1 , the factory for manufacturing liquid crystal cells (which will be abbreviated as “LC cells” hereinafter) and the factory for assembling LC modules are distant from each other. Therefore, the LC cells fabricated in the LC cell fabrication factory are packed and then, transported to the LC module assembly factory. The LC modules finished in the LC module assembly factory are packed again and transported to the entrusting company or the customer designated place. - Since the LC cell and the LC modules have different shapes and different thicknesses, the LC cell and the LC modules have been transported using different packing materials so far. Thus, there is the strong need to save the resources and reduce the transportation cost by contriving these packing and transporting materials. To address this need, various improvements about the packing materials have been proposed.
- A first example of the aforementioned improvements is a container disclosed by the Japanese Unexamined Patent Publication No. 2006-273347. This container is capable of receiving different sized semiconductor chips, and comprises a placement section formed on the surface and an auxiliary placement section formed on the back. When two of the containers whose surfaces are oriented upward are stacked vertically and turned upside down, the semiconductor chip received in the placement section is moved to the auxiliary placement section and received therein. Thus, faceup and facedown of the semiconductor chips can be chosen without transferring the semiconductor chips themselves.
- A second example of the aforementioned improvements is a placement jig or tray disclosed by the Japanese Unexamined Patent Publication No. 2006-143246. This jig comprises three types of depressed parts whose opening areas are different from each other formed in the pocket section, in which the side wall of the pocket section is stepped. Different sized semiconductor chips can be received in the same pocket section. Moreover, inter-layer materials are inserted into the gaps so that the semiconductor chip placed in the pocket section does not jolt during transfer.
- A third example of the aforementioned improvements is a transport tray disclosed by the Japanese Unexamined Patent Publication No. 2010-235142. This transport tray is commonly used for transportation of sub-modules (half-finished goods) and transportation of modules (finished goods) into which the sub-modules are assembled. This tray comprises a first depressed part formed in the first region, a second depressed part formed in the second region which is included in the first region, and a first protruded part formed in the second region which is included in the second region. The sub-module is held in the first depressed part and the module is held in the second depressed part, which means that this tray can be commonly used for both of the sub-module and the module.
- A fourth example of the aforementioned improvements is a placement tray disclosed by the Japanese Unexamined Patent Publication No. 2008-127062. This placement tray comprises two supporting parts in the depressed part for placement, in which the supporting parts have different depths. The article held in the upper position is contacted with the article held in the lower position and held by the same.
- With the container disclosed by the Publication No. 2006-273347 and the placement jig disclosed by the Publication No. 2006-143246, different sized semiconductor chips can be held and transported. However, this container and this jig are adaptable only for change of the semiconductor chip size, and invented taking in-factory transfer into consideration. Therefore, they cannot be used for the aforementioned inter-factory transportation of the LC cells and the LC modules having different shapes and different thicknesses.
- The transport tray disclosed by the Publication No. 2010-235142 can be commonly used for transportation of the sub-modules (half-finished goods) and transportation of modules (finished goods) having different shapes and different thicknesses. However, when the trays are stacked vertically, the overall thickness (height) of this stack varies dependent upon the thickness of the sub-module and the thickness of the module. Thus, an exterior box for receiving the stack of the trays cannot be commonly used.
- With the placement tray disclosed by the Publication No. 2008-127062, the two plate-shaped articles can be received in the depressed part. However, the aim of this tray is to raise the reception or packing density of the same article. Thus, this tray cannot be used for the aforementioned inter-factory transportation of the LC cells and the LC modules having different shapes and different thicknesses.
- The present invention was created to solve the aforementioned existing problems while taking the above-described conventional techniques into consideration.
- An object of the present invention is to provide a transport tray that can be used commonly for inter-factory transportation of two articles (here, a LC cell and a LC module) having different shapes and different thicknesses and that makes it possible to use an exterior box commonly for the inter-factory transportation, and a transporting package and a transporting method using the tray.
- Another object of the present invention is to provide a transport tray that realizes resource saving of the transporting materials and reduction of the transportation cost easily.
- The above objects together with others not specifically mentioned will become clear to those skilled in the art from the following description.
- According to the first aspect of the present invention, a transport tray is provided. This tray, which is formed by molding a sheet-shaped base material to have a desired shape, comprises:
- a first placement section formed on a surface side of the base material; and
- a second placement section formed to overlap with the first placement section on a back side of the base material;
- wherein the first placement section comprises a depressed part having an enough depth for receiving a thin plate-shaped first article;
- the first article placed in the depressed part is held at a predetermined position by a bottom face and a side face that constitute the depressed part;
- the second placement section is formed by a supporting wall having an enough depth for receiving a thin plate-shaped second article, the supporting wall protruding to the back side; and
- the second article placed in a region surrounded by a supporting wall is held at a predetermined position by a bottom face and a side face that constitute the region;
- and wherein when the trays each including the first articles placed in the first placement sections are stacked, the supporting wall of one of the trays is contacted with the first article of another of the trays adjoining thereto is contacted with the first article placed in another of the trays; and
- when the trays each including the second articles placed in the second placement sections are stacked, the bottom face that constitutes the depressed part of one of the trays is contacted with the second article of another of the trays adjoining thereto.
- With the transport tray according to the first aspect of the present invention, the aforementioned structure is provided and therefore, if the first article (e.g., a LC cell) is placed in the first placement section formed on the surface side of the sheet-shaped base material in each of the trays, and these trays are stacked, the supporting wall of one of the trays is contacted with the first article placed in another of the trays adjoining thereto. Thus, the first article can be held in the first placement section stably.
- More over, if the second article (e.g., a LC module) is placed in the second placement section formed on the back side of the sheet-shaped base material in each of the trays, and these trays are stacked, the bottom face that constitutes the depressed part of one of the trays is contacted with the second article placed in another of the trays adjoining thereto. Thus, the second article can be held in the second placement section stably.
- Accordingly, this tray can be used commonly for inter-factory transportation of two articles i.e., the first article and the second article, having different shapes and different thicknesses.
- Furthermore, since the first placement section comprises the depressed part having an enough depth for receiving the first article, the first article is entirely received in the first placement section. Similarly, since the second placement section is formed by the supporting wall having an enough depth for receiving the second article, the second article is entirely received in the second placement section. Thus, the overall height (thickness) of the tray stack formed by stacking the trays in the case where the first article is received in the first placement section is equal to the overall height (thickness) of the tray stack formed by stacking the trays in the case where the second article is received in the second placement section. Accordingly, the same exterior box can be used for transportation of the first article and the transportation of the second article by turning the tray stack upside down.
- In this way, with the transport tray according to the first aspect of the present invention, not only the tray but also the exterior box can be used commonly for the transportation of the first article and that of the second article and as a result, resource saving of the transporting materials and reduction of the transportation cost can be realized easily.
- In a preferred embodiment of the transport tray according to the first aspect of the present invention, the supporting wall is located in such a way that when the trays each including the second articles placed in the second placement sections are stacked, the supporting wall of one of the trays does not interfere with the second article of another of the trays adjoining thereto.
- In another preferred embodiment of the transport tray according to the first aspect of the present invention, the first placement section has an enough size for receiving the first article and an attachment for the first article (e.g., a FPC substrate attached to a LC cell).
- In still another preferred embodiment of the transport tray according to the first aspect of the present invention, the depressed part of the first placement section has an enough depth for receiving the first article and a first cushion, and the supporting wall of the second placement section has an enough depth for receiving the second article and a second cushion.
- In a further preferred embodiment of the transport tray according to the first aspect of the present invention, the first placement section has an enough size for receiving the first article having a size equal to a multiple of a size of the second article to be placed in the second placement section or greater.
- According to the second aspect of the present invention, another transport tray is provided. This tray, which is formed by molding a sheet-shaped base material to have a desired shape, comprises:
- a first placement section formed on a surface side of the base material; and
- a second placement section formed to overlap with the first placement section on the surface side of the base material;
- wherein the first placement section and the second placement section are formed in a depressed part whose side wall is stepped;
- a first portion of the depressed part corresponding to the first placement section is located relatively closer to a surface of the base material and has an enough depth for receiving a thin plate-shaped first article;
- the first article placed in the first portion is held at a predetermined position by a bottom face and a side face that constitutes the first portion;
- a second portion of the depressed part corresponding to the second placement section is located relatively more distant to the surface of the base material and has an enough depth for receiving a thin plate-shaped second article;
- the second article placed in the second portion is held at a predetermined position by a bottom face and a side face that constitutes the second portion;
- and wherein when the trays each including the first articles placed in the first placement sections are stacked, the bottom face that constitutes the first portion of one of the trays is contacted with the first article of another of the trays adjoining thereto; and
- when the trays each including the second articles placed in the second placement sections are stacked, the bottom face that constitutes the second portion of one of the trays is contacted with the second article of another of the trays adjoining thereto.
- With the transport tray according to the second aspect of the present invention, the aforementioned structure is provided and therefore, if the first article (e.g., a LC cell) is placed in the first placement section in each of the trays, and these trays are stacked, the bottom face that constitutes the second part of one of the trays is contacted with the first article placed in another of the trays adjoining thereto. Thus, the first article can be held in the first placement section stably.
- Moreover, if the second article (e.g., a LC module) is placed in the second placement section in each of the trays, and these trays are stacked, the bottom face that constitutes the second part of one of the trays is contacted with the second article placed in another of the trays adjoining thereto. Thus, the second article can be held in the second placement section stably.
- Accordingly, this tray can be used commonly for inter-factory transportation of two articles i.e., the first article and the second article, having different shapes and different thicknesses.
- Furthermore, since the first part of the depressed part corresponding to the first placement section has an enough depth for receiving the first article, the first article is entirely received in the first placement section. Similarly, since the second part of the depressed part corresponding to the second placement section has an enough depth for receiving the second article, the second article is entirely received in the second placement section. Thus, the overall height (thickness) of the tray stack formed by stacking the trays in the case where the first article is received in the first placement section is equal to the overall height (thickness) of the tray stack formed by stacking the trays in the case where the second article is received in the second placement section. Accordingly, the same exterior box can be used for transportation of the first article and the transportation of the second article without turning the tray stack upside down.
- In this way, with the transport tray according to the second aspect of the present invention, not only the tray but also the exterior box can be used commonly for the transportation of the first article and that of the second article and as a result, resource saving of the transporting materials and reduction of the transportation cost can be realized easily.
- In a preferred embodiment of the transport tray according to the second aspect of the present invention, the first portion of the depressed part corresponding to the first placement section has an enough depth for receiving the first article and a first cushion; and the second portion of the depressed part corresponding to the second placement section has an enough depth for receiving the second article and a second cushion.
- According to the third aspect of the present invention, still another transport tray is provided. This tray, which is formed by molding a sheet-shaped base material to have a desired shape, comprises:
- a first placement section formed on a surface side of the base material; and
- a second placement section formed to overlap with the first placement section on a back side of the base material;
- wherein the first placement section comprises a depressed part having an enough depth for receiving a thin plate-shaped first article, the first article placed in the depressed part being held at a predetermined position by a bottom face and a side face that constitutes the depressed part;
- the second section is formed by a supporting wall protruding to the back side of the base material, the supporting wall having an enough depth for receiving a thin plate-shaped second article; the second article placed in a region surrounded by the supporting wall being held at a predetermined position by a bottom face and a side face that constitutes the region;
- and wherein when the trays each including the first articles placed in the first placement sections are stacked, the supporting wall of one of the trays is contacted with the first article of another of the trays adjoining thereto; and
- when the trays each including the second articles placed in the second placement sections are stacked, the supporting wall of one of the trays is not contacted with the second article of another of the trays adjoining thereto, and the bottom face that constitutes the region is contacted with the second article of another of the trays adjoining thereto.
- With the transport tray according to the third aspect of the present invention, the aforementioned structure is provided and therefore, if the first article (e.g., a LC cell) is placed in the first placement section formed on the surface side of the sheet-shaped base material in each of the trays, and these trays are stacked, the supporting wall of one of the trays is contacted with the first article placed in another of the trays adjoining thereto. Thus, the first article can be held in the first placement section stably.
- Moreover, if the second article (e.g., a LC module) is placed in the second placement section formed on the back side of the sheet-shaped base material in each of the trays, and these trays are stacked, the supporting wall of one of the trays is not contacted with the second article placed in another of the trays adjoining thereto but the bottom face that constitutes the region is contacted with the second article placed in another of the trays adjoining thereto. Thus, the second article can be held in the second placement section stably.
- Accordingly, this tray can be used commonly for inter-factory transportation of two articles i.e., the first article and the second article, having different shapes and different thicknesses.
- Furthermore, since the first placement section comprises the depressed part having an enough depth for receiving the first article, the first article is entirely received in the first placement section. Similarly, since the second placement section is formed by the supporting wall having an enough depth for receiving the second article, the second article is entirely received in the second placement section. Thus, the overall height (thickness) of the tray stack formed by stacking the trays in the case where the first article is received in the first placement section is equal to the overall height (thickness) of the tray stack formed by stacking the trays in the case where the second article is received in the second placement section. Accordingly, the same exterior box can be used for transportation of the first article and the transportation of the second article without turning the tray stack upside down.
- In this way, with the transport tray according to the third aspect of the present invention, not only the tray but also the exterior box can be used commonly for the transportation of the first article and that of the second article and as a result, resource saving of the transporting materials and reduction of the transportation cost can be realized easily.
- In a preferred embodiment of the transport tray according to the third aspect of the present invention, the depressed part of the first placement section has an enough depth for receiving the first article and a first cushion, and the supporting wall of the second placement section has an enough depth for receiving the second article and a second cushion.

- The structure of a transport tray according to a first embodiment of the present invention is shown in
FIGS. 2 and 3 . - As shown in
FIGS. 2 and 3 , thetransport tray 10 according to the first embodiment, which is formed to have a desired shape by molding a sheet-shaped base material or member, comprises afirst placement section 12 for receiving aLC cell 30 formed on the side of asurface 11 and asecond placement section 14 for receiving aLC module 40 formed on the side of a back 13. Thetray 10 can be formed by, for example, the popular vacuum forming method - The
LC cell 30 is placed in thefirst placement section 12 in such a way that the longitudinal direction of thecell 30 is along the lateral direction ofFIG. 2 . However, theLC module 40 is placed in thesecond placement section 14 in such a way that the longitudinal direction of themodule 40 is along the vertical direction ofFIG. 3 . Thus, theLC cell 30 and theLC module 40 are placed to be intersected perpendicularly. - As shown in
FIGS. 4A , 4B, 5A and 5B, thefirst placement section 12 is formed by an approximately rectangular depressed part having an enough size for receiving theLC cell 30. TheLC cell 30 is placed in this depressed part to have a direction shown inFIG. 2 in such a way as to be fit into there. In other words, theLC cell 30 placed in the first placement section 12 (approximately rectangular depressed part) is supported by thebottom face 16 a of thefirst placement section 12 formed on its surface side, and is contacted and engaged with the supporting faces 17 a and 17 b which are formed on the inner side faces of the non-depressed part that surrounds thefirst placement section 12, and as a result, thecell 30 is held (positioned) in thefirst placement section 12. The first placement section 12 (approximately rectangular depressed part) is defined by thebottom face 16 a and the supporting faces 17 a and 17 b and has a plan shape shown inFIG. 4A . - As shown in
FIGS. 6A , 6B, 7A and 7B, thesecond placement section 14 is formed by a pair of supportingwalls 15 a and a pair of supportingwalls 15 b which are arranged so as to define a rectangular region having an enough size for receiving theLC module 40. The pair of supportingwalls 15 a are located to have a predetermine distance between them along the vertical direction ofFIG. 6A . The pair of supportingwalls 15 b are located to have a predetermine distance between them along the lateral direction ofFIG. 6A . TheLC module 40 is placed in the rectangular region to have a direction shown inFIG. 3 in such a way as to be fit into there. In other words, theLC module 40 placed in the second placement section 14 (rectangular region) is supported by thebottom face 16 b of thesecond placement section 14 formed on its back side, and is contacted and engaged with the supportingwalls second placement section 14, and as a result, themodule 40 is held (positioned) in thesecond placement section 14. The second placement section 14 (rectangular region) is defined by thebottom face 16 b and the supportingwalls FIG. 5A . - Since the supporting
walls tray 10 toward the side of the back 13, thefirst placement section 12 located on the side of the surface comprises four grooves formed corresponding to the supportingwalls - On the side of the
surface 11 of thetray 10, the part other than thefirst placement section 12, i.e., the surrounding area of thefirst placement section 12, is formed by selectively pressing the sheet-shaped base material or member constituting thetray 10 toward the side of thesurface 11. Thus, thesecond placement section 14 located on the side of the back 12 comprises a depression formed corresponding to the shape of the surrounding area. - In addition, in
FIGS. 2 to 7B , gaps are formed between theLC cells 30 placed in thefirst placement section 12 and thebottom face 16 a, and the supporting faces 17 a and 17 b, and gaps are formed between theLC modules 40 placed in thesecond placement section 14 and thebottom face 16 b, and the supportingwalls LC cells 30 and theLC modules 40 fit into first andsecond placement sections - The dimensional relationship of the
transport tray 10 according to the first embodiment is shown inFIG. 8 . Specifically, the distance between the opposing supporting faces 17 a of thefirst placement section 12 on the side of thesurface 11 is set to be equal to the length of the long sides of the contour of theLC cell 30, and the distance between the inner faces of the opposing supportingwalls 15 b of thesecond placement section 14 on the side of the back 13 is set to be equal to the length of the short sides of the contour of theLC cell 30. - When the
trays 10 are stacked vertically, the distance between the outer end faces of the supportingwalls stacked trays 10 and thebottom face 16 a of another of thestacked trays 10 adjoining thereto is set to be approximately equal to the thickness of theLC cell 30. This is to make it possible to receive theentire cell 30. The distance between thebottom face 16 a of one of thestacked trays 10 and thebottom face 16 b of another of thestacked trays 10 adjoining thereto is set to be approximately equal to the thickness of theLC module 40. This is to make it possible to receive theentire module 40. - The state in which the
trays 10 are stacked and put into an exterior box (packing box) 50 is shown inFIGS. 9A and 9B . As shown inFIG. 9A , theLC cell 30 is placed between the outer end faces of the supportingwalls stacked trays 10 and thebottom face 16 a of another of thestacked trays 10 adjoining thereto downward. As shown inFIG. 9B , theLC module 40 is placed between thebottom face 16 a of one of thestacked trays 10 and thebottom face 16 b of another of thestacked trays 10 adjoining thereto upward, wherein thestacked trays 10 are turned upside down compared with the state ofFIG. 9A . - In this way, the only difference between the case where the
LC cells 30 are placed in thetrays 10 and transported and the case where theLC modules 40 are placed in thetrays 10 and transported is whether thestacked trays 10 are turned upside down or not. Therefore, thesame exterior box 50 can be used commonly for these two cases. - With the
transport tray 10 according to the first embodiment of the present invention, as explained above, thefirst placement section 12 is formed on the side of thesurface 11 and thesecond placement section 14 is formed on the side of the back 13. Thefirst placement section 12 comprises the depressed part having an enough size for receiving the LC cell 30 (a first article to be placed). The depressed part comprises thebottom face 16 a for supporting theLC cell 30 and the supporting faces 17 a and 17 b for preventing displacement of theLC cell 30 along the main surface of thetray 10. Thesecond placement section 14 comprises the protruded part having an enough size for receiving the LC module 40 (a second article to be placed) which are different in shape and thickness from theLC cell 30. The protruded part comprises thebottom face 16 b for supporting theLC module 40 and the supportingwalls LC module 40 along the main surface of thetray 10. For this reason, thetray 10 can be used commonly for inter-factory transportation of two articles (here, theLC cell 30 and the LC module 40) having different shapes and different thicknesses. - Moreover, the height (thickness) of the stacked trays in the case where the
LC cells 30 are placed and transported is equal to that in the case where theLC modules 40 are placed and transported. Therefore, thesame exterior box 50 can be used for both of the transportation of thecell 30 and that of themodule 40 by turning thestacked trays 10 upside down, and as a result, theexterior box 50 can be used commonly for the transportation of thecell 30 and that of themodule 40. - In this way, with the
transport tray 10 according to the first embodiment of the present invention, both of thetray 10 and theexterior box 50 can be used commonly for the transportation of thecell 30 and that of themodule 40 and as a result, resource saving of the transporting materials and reduction of the transportation cost can be realized easily. -
FIG. 25 is a conceptual drawing showing a transporting method according to the first embodiment of the invention. In this method, thetransport tray 10 according to the first embodiment and theexterior box 50 are used. - First, in the LC cell fabrication factory, the
LC cells 30 fabricated are placed in thetransport tray 10. Next, thetrays 10 are stacked and put into theexterior box 50. Thereafter, thebox 50 is transported to the LC module assembly factory. - In the LC module assembly factory, a
FPC substrate 31 is connected to theLC cell 30 and necessary components and/or parts are assembled into theLC cell 30, fabricating theLC modules 40. TheLC module 40 fabricated in this way is placed in thetransport tray 10 which has been used for transporting theLC cells 30. Subsequently, thesetrays 10 are stacked vertically and put into theexterior box 50 which has been used for transporting theLC cells 30, and finally, transported toward a Customer designated factory. - With the transporting method according to the first embodiment, both of the
tray 10 and theexterior box 50 can be used commonly for the transportation of thecell 30 and that of themodule 40 and as a result, resource saving of the transporting materials and reduction of the transportation cost can be realized easily. -
FIGS. 10 , 11, 12A and 12B show a transport tray according to a second embodiment of the present invention. - The
transport tray 10 a according to the second embodiment has the same structure as that of thetransport tray 10 according to the aforementioned first embodiment except that afirst placement section 12 a is set to be larger than that of thetray 10 so that theLC cell 30 to which aFPC substrate 31 is connected can be transferred and that the shape of asecond placement section 14 a is changed according to thefirst placement section 12 a. Therefore, an explanation about the same structure is omitted here by attaching the same reference numerals or signs to the same structural elements, and an explanation about the different structure only is provided below. - As apparent from
FIG. 10 , thefirst placement section 12 a is widened downward so that theLC cell 30 to which aFPC substrate 31 is connected can be received. As apparent fromFIG. 11 , asecond placement section 14 a is widened downward so corresponding to this. - When the
LC cell 30 with theFPC substrate 31 is placed in thefirst placement section 12 a, thetray 10 a is stacked as shown inFIG. 12A . When theLC module 40 is placed in thesecond placement section 14 a, thetray 10 a is stacked as shown inFIG. 12B . - With the
transport tray 10 a according to the second embodiment of the present invention also, similar to the aforementioned first embodiment, thetray 10 a can be used commonly for inter-factory transportation of two articles (here, theLC cell 30 and the LC module 40) having different shapes and different thicknesses and theexterior box 50 also can be commonly used. Therefore, resource saving of the transporting materials and reduction of the transportation cost can be realized easily. -
FIGS. 13 to 17 show a transport tray according to a third embodiment of the present invention. - The
transport tray 10 b according to the third embodiment has the same structure as that of thetransport tray 10 according to the aforementioned first embodiment except that afirst placement section 12 ab is designed so that one Bi-Pane 32 having a size approximately equal to the combination of the eightLC modules 40 can be received and that the shape of asecond placement section 14 b is changed according to thefirst placement section 12 a. Therefore, an explanation about the same structure is omitted here by attaching the same reference numerals or signs to the same structural elements, and an explanation about the different structure only is provided below. - As shown in
FIGS. 13 and 15 , thefirst placement section 12 b is formed to have an enough size for receiving the Bi-Pane 32 having a size approximately equal to the combination of the eightLC modules 40 and as a result, thefirst placement section 12 b is far larger than thefirst placement section 12 of the first embodiment. On the other hand, as shown inFIGS. 14 and 16 , the eightsecond placement sections 14 b are formed so that the eightLC modules 40 can be received separately, wherein the size of thesecond placement sections 14 is approximately equal to that of thesecond placement section 14 of the aforementioned first embodiment. - When the Bi-Pane 32 is placed in the
first placement section 12 b, thetrays 10 b are stacked as shown inFIG. 15 and put into theexterior box 50. When theLC modules 40 are placed in thesecond placement section 14 b, thetrays 10 b are turned upside down and then, stacked as shown inFIG. 16 , and put into theexterior box 50. - The dimensional relationship of the
transport tray 10 b according to the third embodiment is shown inFIG. 17 . Specifically, the distance between the opposing supporting faces 17 a of thefirst placement section 12 b on the side of thesurface 11 is set to be equal to the length of the long sides of the contour of the Bi-Pane 32, and the distance between the inner faces of the opposing supportingwalls 15 b of thesecond placement section 14 b on the side of the back 13 is set to be equal to the length of the short sides of the contour of theLC modules 40. - When the
trays 10 b are stacked vertically, the distance between the outer end faces of the supportingwalls stacked trays 10 b and thebottom face 16 a of another of thestacked trays 10 b adjoining thereto is set to be approximately equal to the thickness of the Bi-Pane 32. This is to make it possible to receive theentire Bi-Pane 32. The distance between thebottom face 16 a of one of thestacked trays 10 b and thebottom face 16 b of another of thestacked trays 10 b adjoining thereto is set to be approximately equal to the thickness of theLC module 40. This is to make it possible to receive theentire module 40. - With the
transport tray 10 b according to the third embodiment of the present invention also, similar to the aforementioned first embodiment, thetray 10 b can be used commonly for inter-factory transportation of two articles (here, the Bi-Pane 32 and the LC module 40) having different shapes and different thicknesses and theexterior box 50 also can be commonly used. Therefore, resource saving of the transporting materials and reduction of the transportation cost can be realized easily. -
FIGS. 18A and 18B show a transport tray according to a fourth embodiment of the present invention. - The
transport tray 10 c according to the fourth embodiment corresponds to one obtained by adding a sheet-shapedcushion 51 to between theLC cell 30 and thetray 10 c and adding a sheet-shaped cushion 52 to between theLC module 40 and thetray 10 c. The other structure is the same as that of thetray 10 of the aforementioned first embodiment. - The shape and the size of the
cushion 51 are the same as those of theLC cell 30, respectively. The shape and the size of the cushion 52 are the same as those of theLC module 40, respectively. - The dimensional relationship of the
transport tray 10 c according to the fourth embodiment is shown inFIGS. 18A and 18B . Specifically, when thetrays 10 c are stacked vertically, the distance between the outer end faces of the supportingwalls 15 b of one of thestacked trays 10 c and thebottom face 16 a of another of thestacked trays 10 b adjoining thereto is set to be approximately equal to the sum of the thickness of theLC cell 30 and the thickness of thecushion 51. This is to make it possible to receive theentire cell 30 and theentire cushion 51. The distance between thebottom face 16 a of one of thestacked trays 10 c and thebottom face 16 b of another of thestacked trays 10 b adjoining thereto is set to be approximately equal to the sum of the thickness of theLC module 40 and the thickness of the cushion 52. This is to make it possible to receive theentire module 40 and the entire cushion 52. - With the
transport tray 10 c according to the fourth embodiment, in addition to the advantages of thetransport tray 10 of the aforementioned first embodiment, an additional advantage that stress (shock) applied to theLC cells 30 and theLC modules 40 during transportation is relaxed is obtained. -
FIGS. 19A , 19B, 20A, 20B, 21A, and 21B show a transport tray according to a fifth embodiment of the present invention. - Different from the
transport trays transport tray 10 d according to the fifth embodiment receives both of theLC cell 30 and theLC module 40 on the side of thesurface 11. - Specifically, the
transport tray 10 d, which is formed to have a desired shape by molding a sheet-shaped base material or member like the above-described first embodiment, comprises afirst placement section 12 d for receiving theLC cell 30 formed on the side of thesurface 11 and asecond placement section 14 d for receiving theLC module 40 formed on the side of thesurface 11. - The
LC cell 30 is placed in thefirst placement section 12 d in such a way that the longitudinal direction of thecell 30 is along the lateral direction ofFIG. 19A . However, theLC module 40 is placed in thesecond placement section 14 d in such a way that the longitudinal direction of themodule 40 is along the vertical direction ofFIG. 20A . Thus, theLC cell 30 and theLC module 40 are placed to be intersected perpendicularly. - The
first placement section 12 d and thesecond placement section 14 d are formed by one depressed part having an enough size for receiving both theLC cell 30 and theLC module 40. The side wall of this depressed part is stepped and comprises, in an upward order from thebottom face 16 a, a supportingface 17 c perpendicular to thebottom face 16 a, a supportingface 18 parallel to thebottom face 16 a, and a supportingface 17 a perpendicular to thebottom face 16 a. Thefirst placement section 12 d is defined by the supportingface 18 and the supporting faces 17 a and 17 b. Thesecond placement section 14 d is defined by thebottom face 16 a and the supporting faces 17 c and 17 d. Therefore, on the side of thesurface 11, thesecond placement section 14 d is formed at a position closer to thebottom face 16 a (at a lower position), and thefirst placement section 12 d is formed at a position more distant from thebottom face 16 a (at an upper position). - As seen from the placement state of the
LC cell 30 and theLC module 40 shown inFIGS. 19A , 19B, 20A, and 20B, theLC cell 30 placed in thefirst placement section 12 d and theLC module 40 placed in thesecond placement section 14 d interfere with each other. Therefore, theLC cell 30 cannot be placed in thefirst placement section 12 d simultaneously with placement of theLC module 40 in thesecond placement section 14 d, wherein thecell 30 is placed to overlap with theunderlying module 40. - As shown in
FIGS. 19A and 19B , theLC cell 30 placed in thefirst placement section 12 d is supported by the supportingface 18 in such a way as to be apart form thebottom face 16 a on the side of thesurface 11, and positioned by the supporting faces 17 a and 17 b. As shown inFIGS. 20A and 20B , theLC module 40 placed in thesecond placement section 14 d is supported by thebottom face 16 a, and positioned by the supporting faces 17 c and 17 d. - In addition, in
FIGS. 19A , 19B, 20A, 20B, 21A, and 21B, gaps are formed between theLC module 40 placed in thesecond placement section 14 d and thebottom face 16 a and the supporting faces 17 c and 17 d, and gaps are formed between theLC cell 30 placed in thefirst placement section 12 d and thebottom face 16 a and the supporting faces 17 a and 18. These gaps are provided to facilitate understanding of the present invention. Actually, these gaps are scarcely generated except for the gaps caused by dimensional errors. - The dimensional relationship of the
transport tray 10 d according to the fifth embodiment is shown inFIG. 21 . Specifically, the distance between the opposing supporting faces 17 a of thefirst placement section 12 d is set to be equal to the length of the long sides of the contour of theLC cell 30, and the distance between the supporting faces 17 c of thesecond placement section 14 d is set to be equal to the length of the short sides of the contour of theLC module 40. - When the
trays 10 d are stacked vertically, the distance between the supportingface 18 of one of thestacked trays 10 d and thebottom face 16 b of another of thestacked trays 10 d adjoining thereto is set to be approximately equal to the thickness of theLC cell 30. This is to make it possible to receive theentire cell 30. The distance between thebottom face 16 a of one of thestacked trays 10 d and thebottom face 16 b of another of thestacked trays 10 d adjoining thereto is set to be approximately equal to the thickness of theLC module 40. This is to make it possible to receive theentire module 40. - The state in which the
trays 10 d are stacked and put into theexterior box 50 is shown inFIGS. 19B and 20B . - With the
transport tray 10 d according to the fifth embodiment, thestacked trays 10 d are not turned upside down between the case where theLC cells 30 are placed and transferred and the case where theLC modules 40 are placed and transferred and therefore, it is apparent that thesame exterior box 50 can be commonly used. In addition, in the fifth embodiment also, cushions can be used so as to superpose on the LC cells and the LC modules in the same manner as described in the aforementioned fourth embodiment. - With the
transport tray 10 d according to the fifth embodiment of the present invention, as explained above, thetray 10 d comprises thefirst placement section 12 d formed on the side of thesurface 11 and thesecond placement section 14 d formed on the same side. Thefirst placement section 12 d comprises the depressed part having an enough size for receiving the LC cell 30 (a first article to be placed), and the supportingface 18 for supporting theLC cell 30 and the supporting faces 17 a and 17 b for preventing displacement of theLC cell 30 along the main surface of thetray 10 d are formed in the depressed part. Thesecond placement section 14 d is formed in the same depressed part as thefirst placement section 12 d to have an enough size for receiving the LC module (a second article to be placed) which are different in shape and thickness from theLC cell 30. Thesecond placement section 14 d comprises thebottom face 16 a for supporting theLC module 40 and the supportingwalls LC module 40 along the main surface of thetray 10 d. For this reason, thetray 10 d can be used commonly for inter-factory transportation of two articles (here, theLC cell 30 and the LC module 40) having different shapes and different thicknesses. - Moreover, the height (thickness) of the
stacked trays 10 d in the case where theLC cells 30 are placed and transported is equal to that in the case where theLC modules 40 are placed and transported. Therefore, thesame exterior box 50 can be used for both of the transportation of thecell 30 and that of themodule 40 without turning thestacked trays 10 d upside down, and as a result, theexterior box 50 can be used commonly for the transportation of thecell 30 and that of themodule 40. - In this way, with the
transport tray 10 d according to the fifth embodiment of the present invention, both of thetray 10 d and theexterior box 50 can be used commonly for the transportation of thecell 30 and that of themodule 40 and as a result, resource saving of the transporting materials and reduction of the transportation cost can be realized easily. -
FIGS. 22A , 22B, 23A, 23B, and 24 show a transport tray according to a sixth embodiment of the present invention. - The
transport tray 10 e according to the sixth embodiment has the same structure as that of thetransport tray 10 d according to the aforementioned fifth embodiment except for the following. - In the
transport tray 10 d of the aforementioned fifth embodiment, both of theLC cell 30 and theLC module 40 are placed on the side of thesurface 11. However, theLC cell 30 thus placed is apart from thebottom face 16 a and only the peripheral area of thecell 30 is supported by the supportingface 18. Therefore, there is an anxiety that thecell 30 is pressed by thebottom face 16 b of the adjoiningtray 10 d to be broken or damaged during transportation. In thetray 10 e of the sixth embodiment, this anxiety is eliminated in the following way. - Specifically, like the above-described first embodiment, the supporting
wall 15 b is formed to protrude on the side of the back 13, thereby raising thebottom face 16 a. Thus, the approximately entirety of thecell 30 placed is supported by thebottom face 16 a. For this reason, there is no anxiety that thecell 30 is pressed by thebottom face 16 b of the adjoiningtray 10 d to be broken or damaged during transportation. - When the
LC cell 30 is placed in thefirst placement section 12 e, thecell 30 is supported by thebottom face 16 a of one of thestacked trays 10 e, as shown inFIG. 22B , and positioned by the supporting faces 17 a and 17 b along the main surface of thetray 10 e. Since thecell 30 is contacted with the supportingwall 15 b of another of thestacked trays 10 e adjoining thereto upward, thecell 30 is positioned along the direction perpendicular to the main surface of thetray 10 e. - When the
LC module 40 is placed in thesecond placement section 14 e, themodule 40 is supported by thebottom face 16 a of one of thestacked trays 10 e, as shown inFIG. 23B , and positioned by the supporting faces 17 c and 17 d along the main surface of thetray 10 e. Since themodule 40 is contacted with thebottom face 16 b of another of thestacked trays 10 e adjoining thereto upward, themodule 40 is positioned along the direction perpendicular to the main surface of thetray 10 e. - The
stacked trays 10 e are not turned upside down in the case of transporting theLC cells 30 and in the case of transporting theLC modules 40. - In the sixth embodiment also, cushions can be used so as to superpose on the LC cells and the LC modules in the same manner as described in the aforementioned fourth embodiment.
- With the
transport tray 10 e according to the sixth embodiment of the present invention, thetray 10 e can be used commonly for the transportation of thecell 30 and that of themodule 40. Moreover, theexterior box 50 can be used commonly for the transportation of thecell 30 and that of themodule 40. As a result, resource saving of the transporting materials and reduction of the transportation cost can be realized easily. - The above-described first to sixth embodiments are embodied examples of the present invention. Therefore, it is needless to say that the present invention is not limited to these embodiments and any other modification is applicable to these embodiments without departing the spirit of the present invention.
- For example, placement and transportation of the
LC cell 30 and theLC module 40 each having a rectangular plan shape is explained in the aforementioned embodiments. However, the present invention is not limited to this. Any other articles can be placed and transported by the transport tray according to the present invention. No limit is applied to the shape and thickness of articles to be placed and transported.
