(Function)
The tray for a plate-like object of the present invention is a tray that holds the plate-like object in a bent state by such a configuration, and without bringing the part having the function of the plate-like object into contact with the other, It is possible to provide a tray that can be stacked, transported and stored easily and efficiently while maintaining a predetermined distance between plates, and that can solve the problem of plate quality caused by vibration. 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. A plate-like object holding portion that is held from the lower side in a bent state, and the frame portion is an overlapping portion when stacking a plurality of trays, and when the trays are stacked a plurality of times, the front and back are in surface contact with each other In a 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, which is a surface on the side on which the plate-like objects are not placed, of the plate-like object support portion. When the end of the lower plate-like object moves upward, a plate-like object end movement restricting member is attached to contact the upper side of the end and restrict the upward movement of the end. This has been achieved.
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. When the end of the lower plate-like object moves upward in a state where a plurality of the trays on which the sheet is placed are stacked, the tray abuts on the upper side of the end and restricts the upward movement of the end. By attaching the plate-like object end movement restricting member, for example, when the plate-like object vibrates due to resonance, it is possible to restrict the end of the plate-like object to rise upward by a predetermined width. Vibration due to resonance of the object can be suppressed or prevented.
In addition, by attaching the plate-like object end movement restricting member, it is possible to restrict the movement of the plate-like object to the upper side by a predetermined width even with respect to the vibration of the plate-like object caused by the outside. . Thereby, it is supposed that the problem of the quality of the plate-like material due to vibration can be solved.
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.

Specifically, the form of the invention of claim 2 in which the plate-like object end movement restriction member is attached to the back surface of the plate-like object supporting portion along at least one pair of two opposing sides.
3. The plate-like-object-end movement restricting member according to claim 2, wherein one surface of the plate-like-object-end-movement-limiting member is arranged on the plate-like object supporting portion in a cross section in the thickness direction perpendicular to the side portion of the frame portion along which As the thickness of the plate decreases toward the center of the tray along the back of the plate, when the plate moves, the plate end movement restricting member reliably contacts only the end of the plate. , Others are not in contact.
In particular, when the plate-like object end movement restricting member is brought into contact with only the upper end surface of the plate-like object to suppress vibration when the plate-like object moves upward, the plate-like object end movement restricting member is restricted. The contact area between the member and the functional surface of the plate-like object can be reduced.
As a result, it is difficult to cause quality adverse effects due to contact.

Alternatively, in the second aspect of the present invention, as the plate-like object end movement restricting member, one surface of the plate-like object movement restricting member is a plate-like object supporting portion in a cross section in the thickness direction perpendicular to the side of the frame portion along which it is formed. There is also a mode in which the thickness is uniform over the entire cross section along the back surface of the plate, 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 contact a desired portion of the surface of the plate-like object.

Moreover, as a material of the said plate-shaped object edge part movement restriction member, what consists of thermoplastic resins is mentioned.
The plate-like object end movement restricting member is a member having a special shape and 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 of claim 6, 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, the form of the invention of claim 7 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 6, 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.
In the form of the invention of claim 7, for example, the plate in the case where the square plate-like object is held horizontally while supporting only the two corner portions arranged on the diagonal of the square plate-like object. It is held as a state along the shape of the vertical deflection, which is bent only by its own weight, or as a shallower deflection state in the vertical direction.
In addition, the curved shape along each side of the frame portion of the plate-like object holding part is a form formed in a part of the outer peripheral shape of an arc or an ellipse, or a part of the outer peripheral shape of an arc or a polygon, or In addition, a part of the outer peripheral shape of the arc or ellipse and the straight line are in a form that is one of the combined shapes, so that it can be stably held in a bent state.
The plate-like object holding portion in the form of the invention of claim 7 is such that the upper surface along each side of the four sides of the frame portion is curved downward, and along the four sides of the frame portion. The end of the plate is supported along the four sides, and the plate is bent downward in the vertical direction along the four sides of the frame. By adopting such a form, for example, a substrate for forming a color filter for a display panel, which is a size called a sixth generation of 1.5 m × 1.8 m size, is used. In the case where the glass substrate is a plate-like object, in particular, the vibration of the plate-like object can be effectively suppressed.
Moreover, in the form of invention of Claim 7, each side of the four sides of the said frame part is set as the form along the curve of the said plate-shaped object holding | maintenance part along each side. In each side, the end of the plate-like object holding portion along each side can be supported in a bent shape, and a desired bent state can be reliably obtained.

  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 the embodiment of the plate-like object tray 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 a plurality of trays are stacked, and is formed such 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. In a state where a plurality of trays on which plate-like objects are placed are stacked on at least a part of the back surface on which the plate-like object is not placed, the end of the lower plate-like object is A plate-like object end movement restricting member 40 is attached, which is in contact with the upper side of the end part when it moves upward, and restricts the upward movement of the end part.
In this example, the plate-like-object end portion movement restriction members 40a to 40d are attached to all the back surfaces of the plate-like object support portions 30a to 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.

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 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, as the plate-like object end movement restricting member 40, a material made of a thermoplastic resin is preferable 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, if it has the same function, the plate-shaped object edge part movement restriction member 40 material will not be limited to these.

The taper is linearly tapered toward the center side of the frame portion 20.
The shapes of the plate-like object end movement restriction members 40a to 40d are 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. In the state where a plurality of the trays on which the plate-like objects are placed are stacked on at least a part of the back surface on which the plate-like objects are not placed, the lower plate-like object. The plate-like object end movement restricting members 40a to 40d are arranged so that when the end of the plate moves upward due to vibration, the end of the plate abuts on the upper side of the end and limits the upward movement of the end. ing.
2 (c) and 2 (d), when the end portion of the plate-like object 50 moves upward, the plate-like object end portion movement restricting member is the end portion of the plate-like object. Abuts on the upper side.
2 (c) and 2 (d) show a case where the end of the lower plate-like object is not moved upward in a state where a plurality of trays on which the plate-like object is placed are stacked. There is a gap 48 between the plate-like object 50 on the upper tray and the plate-like object end movement restricting members 40a, 40d.
In this example, the gap 48 is linearly widened toward the center side of the frame portion 20.

The plate-like object end movement restriction members 40a to 40d are not limited to the shape of the cross section.
By changing the cross-sectional shapes of the plate-like object end movement restriction members 40a to 40d in the A1-A2 direction and the A3-A4 direction, for example, FIG. 3 (a) and FIG. 2 is a cross-sectional view in the direction corresponding to the A1-A2 direction and the A3-A4 direction in FIG. The thicknesses of the movement restricting members 41a and 41d are small at the center side of the frame portion and greatly changed. When the trays 10 on which the plate-like objects 50 are placed are stacked, the end portions of the lower plate-like objects are The plate-like object end movement restricting members 41a and 41d are brought into contact only with the end surfaces 51 and 52 of the plate-like object 50 when moved upward by vibration, and the plate is moved so as to restrict the upward movement of the end part. Shaped object end movement restriction members 41a to 41d are arranged.
3 (a) and 3 (b) show the case where the end of the lower plate-like object is not moved upward in a state where a plurality of trays on which the plate-like object is placed are stacked. There is a gap 48 in the vicinity of the end surfaces 51 and 52 between the plate-like object 50 of the upper tray and the plate-like object end movement restricting members 41a and 41d.
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 plate-like object end movement restriction members 42a and 42d is constant with a predetermined width of the end, and the center side of the frame part is gradually smaller from the center side. In the state where the thickness is linearly changed and the tray 10 on which the plate-like object 50 is placed is stacked, when the end of the lower plate-like object moves upward by vibration, the end of the plate-like object The plate-like object end movement restricting members 42a to 42d are brought into contact with the desired width only at the end of the plate-like object 50, and the upward movement of the end is restricted. Arranged.
4 (a) and 4 (b) show a case where the end of the lower plate-like object is not moved upward in a state where a plurality of trays on which the plate-like object is placed are stacked. There is a gap 48 between the plate-like object 50 of the upper tray and the plate-like object end movement restricting members 42a, 42d, and this gap 48 is a predetermined constant gap from the end, Further, on the center side of the frame portion, the gap gradually increases on the center side.
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 plate-like object end portion movement restriction members 43a and 43d is constant with a predetermined width of the end portion, and the center side of the frame portion is gradually smaller from the center side. In this case, when the tray 10 on which the plate-like object 50 is placed is overlapped, the end of the lower plate-like object is moved upward by vibration, The plate-like object end movement restricting members 43a and 43d are brought into contact with a desired width only at the end of the plate-like object 50, and the plate-like object end movement restricting member is restricted so as to restrict the upward movement of the end. 43a-43d are arranged.
5 (a) and 5 (b) also show a case where the end of the lower plate is not moved upward in a state where a plurality of trays on which the plate is placed are stacked. There is a gap 48 between the plate-like object 50 on the upper tray and the plate-like object end movement restricting members 43a, 43d, and this gap 48 is a predetermined constant gap from the end, Further, on the center side of the frame portion, the gap gradually increases on the center side.
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 thickness of the plate-like object end movement restricting members 44a and 44d is constant over the entire width of the plate-like object supporting portion 30a, and the tray 10 on which the plate-like object 50 is placed. When the end of the lower plate-like object is moved upward by vibration, the plate-like object end movement restricting members 44a and 44d are moved to a desired width only at the end of the plate-like object 50. The plate-like object end part movement restricting members 44a to 44d are arranged so as to make contact with each other and restrict the upward movement of the end part.
6 (a) and 6 (b) also show a case where the end of the lower plate-like object is not moved upward in a state where a plurality of trays on which the plate-like object is placed are stacked. There is a gap 48 between the plate-like object 50 on the upper tray and the plate-like object end movement restricting members 44a, 44d. The gap 48 is formed in a plate shape from the end to the center of the part. It is a width over the entire region of the object support portion 30a, and is a predetermined constant gap.

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). Side regions of the plate-like object on which the plate-like end portion movement restriction members similar to the cross-sectional shapes shown in FIGS. Those arranged along are also mentioned as embodiments of the tray for plate-like objects of the present 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 34 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 36 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 shown in the shape, in the region on the back surface side of the plate-like object support portion, the plate-like object end movement restriction member similar to each of the cross-sectional shapes shown in FIGS. What was arranged along the side region is also exemplified as an embodiment 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. 14, the sheet is superposed on the platform 60 </ b> A 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 30e to 30h 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 plate-like-object edge part movement restriction member in each of 4 sides which opposes is mentioned above, it is not limited to this.
A form in which plate-like object end movement restricting members are provided only on two sides of one set facing each other, or a form in which plate-like object end part movement restricting members are provided only on the other two sets of sides, respectively. Can be mentioned.
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.
