Yes.
Specifically, the base material supports the whole, and the frame inner region is supported by the frame portion larger than the plate-like material, and the plate-like material is vertically lower in the frame inner region of the frame portion. and a plate-like workpiece holding portion for holding from the lower side in a state where flexed, the frame portion is an overlapping portion when superimposing a plurality of trays, the front and back when stacking a plurality of trays are in surface contact with each other In the state in which a plurality of trays on which plate-like objects are placed are stacked on at least a part of the back surface of the plate-like object support portion on which the plate-like objects are not placed. A vibration suppressing member that suppresses vibration in contact with the object is attached, and the plate-like object holding part is bent downward on the upper surface along each of the four sides of the frame part. And support the end along the four sides of the plate-like material along the four sides of the frame, One, in the direction along each side of the four sides of the frame portion, is bent in the vertical direction lower side, by those that supported in a state flexed the platelet have achieved this.
That is, by providing a plate-like object holding portion that holds the plate-like object in a bent state, it is possible to reduce the lift of the plate-like object due to vibrations during conveyance or the like. By attaching a vibration suppression member that suppresses vibration in contact with the plate, it is possible to solve the problem of the quality of the plate-like material due to vibration.
Further, the frame portion is an overlapping portion when stacking a plurality of trays, and when stacking a plurality of trays, the front and back surfaces are in surface contact with each other, that is, the frame portions are stacked in surface contact. Therefore, the storage interval of the plate-like objects can be narrowed, and the transport efficiency in the same volume can be improved.
The storage interval can be narrowed, whereby the storage capacity in the same volume can be improved. As a result, the floor area of the storage container can be reduced as compared with the conventional storage container.
It is possible to realize conveyance with less cracking and scratches due to contact due to the floating of the plate-like object.
The plate-like object holding part has its upper surface along each of the four sides of the frame part curved downward, and the four sides of the plate-like object are along the four sides of the frame part. The end is supported along the part, and is bent downward in the vertical direction in the direction along each of the four sides of the frame part to support the plate-like object in a bent state. Therefore, for example, when a glass substrate having a size of 1.5 m × 1.8 m, which is the sixth generation, is used for forming a color filter for a display panel, a plate is particularly preferable. The vibration of the object can be effectively suppressed.
In addition, each of the four sides of the frame portion has a shape along the curvature of the plate-like object holding portion along each side, so that each side is along each side. The end of the plate-like object holding portion can be supported in a bent shape, and a desired bent state can be reliably obtained.
For example, in the case where a square plate is supported horizontally by supporting only two corners arranged diagonally to the square plate, the vertical plate is bent only by its own weight, It holds as a state along the shape of the bending, or as a bending state shallower in the vertical direction than this.
The curved shape along each side of the frame portion of the plate-like object holding portion is formed in a part of the outer peripheral shape of an arc or an ellipse, or a part of an arc, a polygonal outer shape, or an arc It is possible to stably hold in a bent state by adopting a form that is a combination of a part of the outer peripheral shape of an ellipse and a straight line.

In the cross section in the thickness direction perpendicular to the side portion of the sheet, the thickness of the cross-section is reduced toward the center of the tray along one surface along the back surface of the plate-like object support portion. By doing so, the vibration suppressing member reliably contacts only the end portion of the plate-like object, and does not contact the others.
Furthermore, the contact area between the vibration suppressing member and the functional surface of the plate-like object can be reduced by adopting the form of the invention according to claim 4 that suppresses vibration by contacting only the end face of the plate-like object. It is possible.
As a result, it is difficult to cause quality adverse effects due to contact.
As such a vibration suppressing member, in the cross section in the thickness direction perpendicular to the side portion of the frame portion along which it is formed, the other surface opposite to the one surface is formed of one or more of a tapered shape and a linear shape. The form is mentioned.

A shape in which the thickness of the plate is uniform throughout the cross section, and the plate is in contact with the entire region where the plate is attached.
In the case of this form, it is possible to hold down a desired portion of the surface of the plate-like object.

In addition, examples of the material of the vibration suppressing member include those made of a thermoplastic resin.
The vibration suppressing member is a member having a special shape and is a member in contact with the plate-like object.
For this reason, the thermosetting resin or the like whose shape is processed by cutting or the like becomes a problem of dust generation, and costs and time are required.
On the other hand, since the shape of the thermoplastic resin is processed by thermal processing, dust generation does not become a problem and cost and time can be reduced.

As the plate-like object holding part, both ends of the plate-like object are supported along one opposite two sides of the four sides of the frame part, and on the other two opposite sides of the four sides of the frame part. The upper surface along each side of the four sides of the frame part and the form of the invention according to claim 8, wherein the plate-like object is supported by bending downward in the vertical direction. , Curved downward, supporting the end portions along the four side portions of the plate-like object along the four sides of the frame portion, and directions along the four sides of the frame portion In addition, a form of the invention of claim 9 is provided in which the plate-like object is supported by being bent downward in the vertical direction.
Further, in these forms, the plate is disposed only at the peripheral portion of the plate-like object to be supported and supports the peripheral portion of the plate-like object, and the region corresponding to the internal region of the plate-like object to be held is an opening. And a form that is arranged so as to straddle the inner region of the held plate-like object and supports the plate-like object also in the inner region.
In the form of the invention of claim 8, when the square plate-like object is supported by only two opposite sides and held horizontally, it is bent only by its own weight, and is bent in the vertical direction. It is held as a state along the shape or as a bent state shallower in the vertical direction than this .

  Examples of the plate-like material include a color filter forming substrate for a display panel or an intermediate process substrate for producing the color filter forming substrate.

As will be further described, when the plate-like object of the unit is held by the tray, the plate-like object and the plate-like object holding part are in a predetermined positional relationship with the plate-like object being bent with respect to the frame part. Therefore, even if the tray holding the plate-like object of such a unit is overlapped in surface contact with the frame part, the plate-like objects can maintain the distance by the thickness of the frame. It becomes.
For example, as shown in a schematic cross-sectional view in FIG. 10A, when three trays are stacked in a state where the plate-like object 50 is bent, the plate-like objects 50 of the respective trays are the same as indicated by thick dotted lines. The pitch interval maintains the thickness of the frame portion 20.
FIG. 10A shows the stacking of the trays at the cross-section at B1-B2 in FIG. 9C showing a state where the plate-like object 50 is placed on the tray 10 of the embodiment described later. Is.
Although not explicitly shown here, the plate-like object holding part has a shape along the plate-like object 50, and the thickness of the plate-like object holding part needs to be thinner than the thickness of the frame part 20, and some bending is caused. In consideration of variation and vibration, it is preferable that the thickness of the frame portion 20 be sufficiently smaller.
When transporting and storing the trays in a stacked state in this way, a dedicated pedestal 60 having a shape as shown in FIG. c) A frame-shaped pedestal 20a as shown in FIG.

One example of a reference embodiment of the tray for plate-like objects of the present invention will be described with reference to FIG.
The tray 10 for the plate-like object of the present example is a tray that holds the plate-like object on the upper side thereof with the surface direction of the rectangular and rigid plate-like object as the horizontal direction, and the plate-like object A plurality of trays for transportation or storage, which are used for transportation or storage in a state of being loaded, and are a base material that supports the whole. The plate-like object holding part 30 that is supported by the frame part 20 along the four sides of the frame part 20 and holds the plate-like object from the lower side in a state where the plate-like object is bent downward in the vertical direction. And.
The frame portion 20 is an overlapping portion when stacking a plurality of trays, and is formed so that the front side surface 20S1 and the back side surface 20S2 are in surface contact with each other when stacking a plurality of trays. A vibration suppression member that suppresses vibration by contacting the plate-like object in a state where a plurality of trays on which the plate-like object is placed are stacked on the back surface, which is the surface on which the plate-like object is not placed, of the support member 30. 40 is attached.
In this example, each vibration suppression member 40a-40d is attached to all the back surfaces of the plate-like object support portions 30a-30d along the four sides of the frame portion 20.
The plate-like object holding part 30 is composed of support parts 30a to 30d that are in contact with and supported by the plate-like object 50. The support parts 30b and 30d are arranged along two opposing sides of the four sides of the frame part 20. Next, both ends of the plate-like object 50 are supported, and are bent downward in the vertical direction in the direction along the other two opposite sides of the four sides of the frame portion by the support portions 30a and 30c. Is to support.
Although the plate-like object holding unit 30 is curved so as to follow the bending of the plate-like object 50 to be held, in this example, the curved shape is close to the bending shape in the bending direction due to the weight of the plate-like object. It is set as a shape and each support part 30a-30d is made to follow the plate-shaped object 50. FIG.
Here, the “bending shape in the bending direction due to the weight of the plate-like object” means that the plate-like object in the case where the two opposite sides of the square plate-like object are supported and held horizontally. It means the shape of the vertical deflection that is bent only by its own weight.
The frame portion 20 is an overlapping portion when a plurality of trays 10 are stacked, and is formed such that the front and back of the trays 10 are in surface contact with each other when stacking a plurality of trays 10. In any side, the front and back surfaces of each side are flat, and the front and back surfaces of each side are located on one plane, but the shape is not limited to this.
Moreover, in this example, the plate-shaped object holding | maintenance part 30 is distribute | arranged only to the peripheral part of the plate-shaped object 50 hold | maintained, and supports the peripheral part of the plate-shaped object 50, The plate shape hold | maintained An area corresponding to the internal area of the object 50 is an opening.
Examples of the plate-like material 50 include a color filter forming substrate for a display panel or an intermediate process substrate for producing the color filter forming substrate, but are not limited thereto.
By adopting such a configuration, the tray that holds the plate-like object in a bent state maintains a predetermined distance between the plate-like objects without bringing the portion having the function of the plate-like object into contact with the others. In this state, it is possible to provide a tray that can be stacked, transported and stored easily and efficiently, and can solve the problem of the quality of the plate-like material caused by vibration.
The frame portion 20 is preferably made of a material having a high strength and a light weight, such as aluminum.
Moreover, it is preferable that each support part 30a-30d of the plate-shaped object holding | maintenance part 30 is also a high intensity | strength and lightweight material, for example, uses aluminum as a base material and uses a cushioning material for the part which contacts the plate-shaped object 50 The form to provide is preferable.
Further, the vibration suppressing member 40 is preferably made of a thermoplastic resin from the viewpoint of vibration suppression.
Further, among thermoplastic resins, polyamide resins such as polyethylene (PE), polypropylene (PP) nylon 66 and nylon 610, polyether ether ketone (PEEK) and polyimide are particularly desirable.
In addition, as long as it has the same function, the material of the vibration suppression member 40 is not limited to these.
The form which makes the vibration suppression member 40 arrange | position the material which has cushioning properties in part or the whole is also mentioned.

In this example, as shown in FIG.1 (d), the vibration suppression members 40a-40d are distribute | arranged to each support part 30a-30d of the plate-shaped object holding | maintenance part 30 over the substantially whole surface, respectively.
And as shown to FIG.1 (b) and FIG.1 (c), the said vibration suppression members 40a-40d are respectively the cross sections of the frame part 20 in the cross section of the thickness direction orthogonal to the side part of the frame part which it follows. Tapered linearly toward the center.
The shape of the vibration suppressing members 40a to 40d is not limited to this.

When the plate-like object 50 is placed on the tray 10 of this example, the plate-like object 50 is bent downward as shown in FIG.
When two trays 10 of the present example on which the plate-like object 50 is placed are stacked, as shown in FIG. 2B, the front and back surfaces of the frame portion 20 are overlapped with each other. The vertical pitch between the objects is the thickness of the frame portion 20.
Similarly, three or more can be stacked.
In this example, the state between two overlapping trays in the cross section corresponding to the A1-A2 direction and the A3-A4 direction in FIG. 1A is as shown in FIGS. 2C and 2D, respectively. Therefore, the vibration suppressing members 40a to 40d are in contact with each other only at the end portion of the plate-like object 50 to suppress vibration.

The vibration suppressing members 40a to 40d are not limited to the shape of the cross section.
By changing the cross-sectional shapes of the vibration suppressing members 40a to 40d in the A1-A2 direction and the A3-A4 direction, for example, in FIG. 3A and FIG. FIG. 2B is a cross-sectional view corresponding to the A1-A2 direction and the A3-A4 direction in FIG. 2B in a state where the trays 10 are stacked, but in the vicinity of the end surface, the thickness of the vibration suppressing member 41a is small on the center side of the frame portion. Thus, the vibration suppressing members 41 a and 41 d are brought into contact only at the end surfaces 51 and 52 of the plate-like object 50 in a state where the trays 10 on which the plate-like objects 50 are placed are stacked.
4 (a) and 4 (b) are also in the A1-A2 direction and A3-A4 direction in FIG. 2 (b), respectively, in a state where the trays 10 on which the plate-like objects 50 are placed are stacked. Although it is a cross-sectional view in a corresponding direction, the thickness of the vibration suppressing member 42a is made constant with a predetermined width at the end, and the thickness of the center side of the frame portion is changed linearly so that the center side gradually becomes smaller. In the state where the trays 10 on which the plate-like objects 50 are placed are stacked, the vibration suppressing members 42 a and 42 d are brought into contact with each other only at the end portions of the plate-like objects 50 with a desired width.
5 (a) and 5 (b) are also in the A1-A2 direction and A3-A4 direction in FIG. 2 (b), respectively, in a state where the trays 10 on which the plate-like objects 50 are placed are stacked. Although it is a cross-sectional view in a corresponding direction, the thickness of the vibration suppressing member 42a is made constant with a predetermined width at the end, and the thickness of the center side of the frame portion is changed in a curved manner so that the center side gradually becomes smaller. Also in this case, the vibration suppressing members 43a and 43d are brought into contact with only a desired width at the end of the plate-like object 50 in a state where the trays 10 on which the plate-like objects 50 are placed are stacked.
6 (a) and 6 (b) are also in the A1-A2 direction and A3-A4 direction in FIG. 2 (b), respectively, in a state where the trays 10 on which the plate-like objects 50 are placed are stacked. Although it is a cross-sectional view in a corresponding direction, the vibration suppression member 42a has a constant thickness over the entire region of the plate-like object support portion 30a, and vibration is generated in a state where the trays 10 on which the plate-like objects 50 are placed are stacked. The suppressing members 44a and 44d are brought into contact with each other with a width over the entire region of the plate-like object support 30a of the plate-like object 50.

In the tray 10 of this example, as shown in FIG. 1A, each side of the frame portion 20 is on one plane, and the four sides of the frame portion 20 are in a plate shape along one opposing two sides. Supports both ends of the object 50, supports the plate-like object by bending it vertically downward in the direction along the other two opposite sides of the four sides of the frame 20, and holds the plate-like object. The portions 31a to 31d are disposed only on the peripheral portion of the plate-like object to be held, and support the peripheral portion of the plate-like object.
And the area | region corresponding to the internal area | region of the plate-shaped object hold | maintained is an opening.
In the plate-like object tray 10 of the present example, the shape of the plate-like object holding unit 30 follows the vertical bending shape due to the weight of the plate-like object when only two opposing sides of the plate-like object are supported. However, it is usually formed along a similar shape of a bent shape that is shallower than the bent shape in the vertical direction due to its own weight.
In addition, as described above, here, the “vertical deflection shape due to the weight of the plate-like object” refers to two opposing sides of the square plate-like object when the square plate-like object is supported. This means a shape of bending in the vertical direction, which is bent only by the weight of the plate-like object when it is held horizontally while supporting only.
When the whole plate-like object 50 is held horizontally, for example, on a strong flat plate, as shown in FIG. 13 (a), the plate-like object 50 can be kept in a horizontal state without being bent. When only the sides 50a and 50b are supported and held, they are bent by their own weight as shown in FIG.
It says such a bent shape.

By holding the plate-like object in a bent state in this way, an effect of suppressing the amount of vibration of the plate-like object with respect to the vertical vibration transmitted from the outside can be obtained as compared with the case where the plate-like object is held in a horizontal state.
This is because a plate-like object that is originally straight is bent, and a force to restore it (restoring force) works, so this restoring force is a force that counteracts the vibration force from the outside, and the amount of vibration is suppressed. This is probably because of this.

Here, when the plate-like object tray 10 of this example shown in FIG. 1A (corresponding to 10 in FIG. 9A) is used, the plate-like object 50 is mounted and the tray on which the plate-like object 50 is mounted. A simple explanation will be given based on FIGS. 9A to 9D.
First, the plate-like object tray 10 of the present example is prepared (FIG. 9A), and the plate-like object 50 is placed on the respective support parts 30a to 30d so that the peripheral parts thereof are placed on the respective support parts 30a to 30d. When placed on 30, the plate-like object 50 is supported by the support portions 30 b and 30 d at both ends thereof along one opposing two sides of the four sides of the frame portion 20, and the support portion 30 a. , 30c in a state along this, is supported by being bent downward in the vertical direction in the direction along the other two opposite sides of the four sides of the frame portion. (FIG. 9B to FIG. 9C)
In this way, the plate-like object 50 is mounted on the tray 10 in a bent state.
Next, in this way, two trays on which the plate-like object 50 shown in FIG. 9C is mounted are stacked (FIG. 9E), and the plate-like object 50 shown in FIG. The mounted trays are stacked (FIG. 9f), and the three are in a stacked state.
The frames are stacked in surface contact with each other, and an overlapping cross section at a portion corresponding to B1-B2 in FIG. 9C is as shown in FIG.
In this way, the layers are sequentially stacked.
Alternatively, the same tray on which the plate-like object 50 is not mounted is placed on the upper side of the tray on which the plate-like object 50 shown in FIG. 9C is mounted, and the plate-like object 50 is similarly placed thereon. It is placed on the plate-like object holding part 30 so that the peripheral portion is placed on each of the support parts 30a to 30d, and two trays on which the plate-like objects 50 are mounted are stacked. (Fig. 9 (e))
Furthermore, on this, the same tray on which the plate-like object 50 is not mounted is placed, and further, the plate-like object 50 is similarly placed thereon so that the peripheral portion thereof is placed on each of the support portions 30a to 30d. It is placed on the plate-like object holding unit 30 to obtain a stack of three trays on which the plate-like objects 50 are mounted. (Fig. 9 (f))
In this way, the layers are sequentially stacked.
In order to support the entire stack, a base 60 as shown in FIG. 10B is usually used, or a shape corresponding to the frame of the tray as shown in FIG. 10C is used. The frame part 20a is used.

As described above, the plate-like object tray 10 of this example is sequentially stacked in a state where only one plate-like object 50 is accommodated, and by accommodating the plate-like object 50 in a bent state. Since the vibration of the plate-like object 50 can be reduced, the storage interval can be greatly reduced.
For example, in a conventional storage box (not shown) that stores a plurality of plate-like objects in a vertical state, the plate-like object that is flexible because it is large and thin is horizontal to prevent it from coming into contact with an adjacent plate-like object. It was necessary to arrange them at appropriate intervals.
Specifically, a 730 mm × 920 mm size color filter forming substrate called G4 required a 15 mm pitch, and a G100 called 1100 mm × 1300 mm, 1100 mm × 1250 mm, 1200 mm × 1300 mm size required a 20 mm pitch, In the tray for plate-like objects of this example, the size of 1500 mm × 1850 mm called G6 was able to be about 10 mm pitch.
At this time, the thickness of the frame was about 10 mm.

The tray for plate-like objects of the present invention is not limited to the above.
Similarly to the tray 10 of this example, both ends of the plate-like object 50 are supported along one opposing two sides on one plane, and the four sides of the frame portion 20 are along the other two opposing sides. In order to support the plate-like object by bending downward in the vertical direction, for example, FIG. 7 (a), FIG. 7 (b), FIG. 8 (a) to FIG. And a tray showing the surface of the tray.
The outer shape of the corresponding back frame portion and plate-like object support portion is the shape shown in FIG. 7 (a1), FIG. 7 (b1), and FIG. 8 (a1) to FIG. 8 (d1). In the region of these plate-like object support portions 31 to 36, the vibration suppressing members similar to the cross-sectional shapes shown in FIGS. 3 to 6 are arranged along the side region of the plate-like object to be placed. A thing is also mentioned as embodiment of the tray for plate-shaped objects of this invention.
In the tray 10a shown in FIG. 7A and FIG. 7A1, the other two sides of the frame portion 20 are fixedly placed along a plate-like object supporting portion along each side.
The tray 10b shown in FIG. 7B and FIG. 7B1 has a plate-like object 50 so that the four sides of the frame portion 20 are on one plane and the two opposing sides are in the same manner as the tray of this example. However, the plate-like object holding part 32 is arranged so as to straddle the entire inner region of the plate-like object to be held, and supports the plate-like object also in the inner region.
The tray 10c shown in FIG. 8A and FIG. 8A1 has four sides of the frame portion 20 on one plane and supports both ends of the plate-like object 50 along one opposing two sides. However, the plate-like object support portion 33 along the other two sides is waved.
The tray 10d shown in FIGS. 8B and 8B1 also supports both ends of the plate-like object 50 so that the four sides of the frame portion 20 are on one plane and the two opposing two sides are along. However, the plate-like object support portion 33 along the other two sides is recessed downward in a linear combination shape.
The tray 10e shown in FIG.8 (c) and FIG.8 (c1) also supports the both ends of the plate-shaped object 50 so that four sides of the frame part 20 may be on one plane, and it may be along one opposing two sides. However, the plate-like object holding part 35 is arranged in a plurality of strips so as to straddle the entire inner region of the plate-like object to be held, and supports the plate-like object also in the inner region. The plate-like object support portion 35 is curved downward in the direction along the direction.
The tray 10f shown in FIG. 8D and FIG. 8D1 also supports both ends of the plate-like object 50 so that the four sides of the frame portion 20 are on one plane and the two opposing two sides are along. However, the plate-like object holding part 35 is arranged in a plurality of strips so as to straddle the entire inner region of the plate-like object to be held, and supports the plate-like object also in the inner region. The plate-like object support portion 36 is waved in the direction along the direction.

Further, unlike the tray 10 of the present example, a base material that supports the whole, a frame inner region is supported by a frame portion larger than the plate-like object, and four sides of the frame portion, and the frame inner region of the frame portion A plate-like object holding part that holds the plate-like object from the lower side in a state where the plate-like object is bent downward in the vertical direction, and the plate-like object holding part is provided on each of the four sides of the frame part. Each of the upper surfaces along the sides is curved downward, supports the edges along the four sides of the plate-like object along the four sides of the frame, and the frame In the direction along each side of the four sides of the part, it is bent downward in the vertical direction to support the plate-like object in a bent state, and the frame part is an overlapping part when stacking a plurality of trays. FIG. 11 (a), FIG. 12 (a), and FIG. 12 (b) are formed so that the front and back of the trays are in surface contact with each other when a plurality of trays are stacked. In the tray showing the shape, in the region on the back surface side of the plate-like object supporting portion, along the side region of the plate-like object on which the vibration suppressing member similar to each of the cross-sectional shapes shown in FIGS. These are also provided as embodiments of the tray for plate-like objects of the present invention.
In these trays, each of the four sides of the frame portion has a shape along the curvature of the plate-like object holding portion along each side.
Also in these trays, when a plate-like object is held by the tray, the plate-like object and the plate-like object holding part are in a state of a predetermined positional relationship with the plate-like object being bent with respect to the frame part. Therefore, the vibration of the plate-like object can be reduced.
Moreover, even if the tray which hold | maintained such a plate-shaped object is surface-contacted and piled up in a frame part, plate-shaped objects can maintain a space | interval only by the thickness of a frame.
Therefore, the storage interval can be greatly reduced.

The mounting of the plate-like object 50 and the stacking of the tray on which the plate-like object 50 is mounted when the plate-like object tray 11 is used will be briefly described with reference to FIGS. 11 (a) to 11 (d).
First, the plate-like object tray 11 is prepared (FIG. 11A), and the plate-like object 50 is placed on the plate-like object holding portion 30A so that the peripheral portion thereof is placed on each of the support portions 30e to 30h. When placed, the plate-like object 50 is supported by the four support portions 30 e to 30 h along the four sides of the frame portion 20, and the ends of the sides are supported. It is supported in a state of being bent downward in the vertical direction in the direction along each side. (FIG. 11 (b) to FIG. 11 (c))
In this way, the plate-like object 50 is mounted on the tray 11 in a bent state.
Next, the trays on which the plate-like objects 50 shown in FIG. 11C are mounted in this manner are sequentially stacked with their frame portions 20 in surface contact with each other. (Fig. 11 (d))
In this way, stacking of trays on which plate-like objects are placed with the frame portions in surface contact is performed.
Actually, as shown in FIG. 14B, the sheet is superposed on the platform 60A and transported or the like.
As shown in FIG. 15, the tray 11 (corresponding to 11 in FIGS. 15B and 11A) holding the plate-like object 50 on the pedestal 60A (equivalent to 60A in FIGS. 15A and 14). ) In a curved state (FIG. 15C), and further, the tray 11 holding the plate-like object 50 is placed.
As shown in FIG. 14, the upper surface 61 s to 64 s of the four sides 61 to 64 of the base 60 </ b> A for stacking the trays 11 has a shape that matches the shape of the frame.
The stacking method is not limited to this.
When the trays 11a and 11b are used, the loading of the plate-like object onto the tray and the stacking of the trays are basically performed in the same manner as described above.

The tray 11 shown in FIG. 11 (a) is shaped like a belt so as to fix the plate-like object holding portions 31e to 31h along the respective sides of the frame portion 20 and to support only the peripheral portion of the plate-like object to be held. It is arranged to support the peripheral portion of the plate-like object, and an area corresponding to the inner area of the plate-like object to be held is an opening.
A tray 11 a shown in FIG. 12A is provided with plate-like object holding portions 30 </ b> B that are fixed along the four sides of the frame portion 20 and straddle the entire inner region of the frame portion 20.
The tray 11b shown in FIG. 12 (b) has a structure in which a plate-like object holding portion 30i is further arranged with respect to the tray 11 shown in FIG. 11 (a), and in the internal region of the plate-like object to be held. It can be supported by the plate-like object holding part 30i.
In the above plate-shaped object tray, the shape of the plate-shaped object holding portion is a vertical bending shape due to the weight of the plate-shaped object when only the two corner portions arranged on the diagonal of the plate-shaped object are supported. , Or a similar shape of a bent shape shallower than the bent shape in the vertical direction due to the weight of the plate-like object.
As described above, here, “vertical deflection due to the weight of the plate-like object” means that the square plate-like object is arranged diagonally when it is supported. This means a vertical bending shape that is bent only by the weight of the plate-like object when only two corner portions are supported and held horizontally.
When the entire plate-like object 50 is held horizontally, for example, on a strong flat plate, as shown in FIG. 13 (a), the plate-like object 50 can be kept horizontal without being bent. When only the two corner portions 50A and 50B to be arranged are supported and held, they are bent by their own weight as shown in FIG.
It says such a bent shape.

Here, mounting and stacking of plate-like objects according to an example of a conventional tray will be briefly described with reference to FIG.
The tray 110 shown in FIG. 16A includes a frame portion 120 that is an overlapping portion and a bottom portion (support portion) 130 on which a plate-like object is mounted. The bottom portion (support portion) 130 is fixed to the frame portion, It is a strong plate-like material that covers the entire area inside the frame of the portion 120, and even if a plate-like object is mounted horizontally on it, it does not bend due to its own weight.
In the case of this conventional tray 110, for example, a plate-like object mounted on the bottom 130 in a horizontal state is sequentially stacked on the frame portion (FIGS. 16A to 16C), Two trays on which plate-like objects are mounted are stacked (FIG. 16D), and three trays are stacked (FIG. 16E).
In this way, the desired number of stacks is obtained. In this conventional tray 110, the plate-like object is just mounted on the bottom, and is displaced by vibrations such as transportation, so that the functional surfaces come into contact with each other. In some cases, the edges may be damaged due to scraping, or dust may be generated, resulting in quality problems.
On the other hand, since the trays of the present invention are all mounted in a bent state in the lower side in the vertical direction, it is possible to reduce the lift of the plate-like object due to vibrations during transportation or the like. Problems can be eliminated.
And especially the vibration of a plate-shaped object can be reduced.

The present invention is not limited to the above.
Although what provided the vibration suppression member in each of the 4 sides which oppose is mentioned above, it is not limited to this.
Examples include a mode in which vibration suppression members are provided only on two sides of one set facing each other, or a mode in which vibration suppression members are provided only on two sides of the other set.
In addition, for example, the curved shape of the plate-like object holding portion is a circular arc, a partial outer shape of a polygon or an ellipse, or a shape obtained by combining a part of the outer peripheral shape of an arc or an ellipse with a straight line. The form which was made is also mentioned.
Further, in the above tray, a positioning mechanism for positioning when stacking the trays is not clearly shown, but, for example, concave and convex positioning portions that fit each other are provided on the front and back of the frame portion.
Alternatively, a mechanism for locking the position is provided in the frame portion.
