Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rectangular thin plate storage device for storing rectangular thin plates made of plate glass or the like.

[0002]

2. Description of the Related Art As an apparatus for storing and transporting a large number of rectangular thin glass sheets, for example, Japanese Patent Laid-Open No. 2000-168870 is known.
The one disclosed in the publication is conventionally known. This known device is constructed by mounting at least a floor portion and a wall portion provided on one surface on a frame body, and a large number of glass plates are stored in a vertically standing state. In order to support the glass plate, a floor beam is provided on the floor with a large number of positioning grooves for vertically positioning the plate glass at a specified pitch interval, and a wall beam with positioning grooves on the wall part with the same pitch interval. Further, a horizontal beam having similar positioning grooves is mounted at a position above the wall portion of the wall portion where the wall beam is provided and at a position opposite to the wall portion.

In the apparatus constructed as described above, the glass plate is inserted into the positioning groove from above both lateral beams, and the lower end portion of the glass plate is provided on the floor through the positioning groove of the wall beam. It is stored so as to be inserted into the positioning groove. Further, the groove width of the positioning groove is set to be somewhat larger than the width dimension of the glass plate so that the glass plate can be smoothly inserted into each of the positioning grooves described above. Therefore,
The stored glass plate cannot be fixedly held by the positioning groove.Therefore, a support should be placed between both horizontal beams to prevent the glass plates from collapsing due to vibration during transportation. ing.

[0004]

By the way, in the above-mentioned prior art, the glass plate is stored by inserting it from above between both lateral beams, and when the glass plate is taken out, it is placed above. You have to pull it up. In other words, it is necessary to displace the glass plate in the direction of its own weight when storing it, and to displace it in the direction opposite to its own weight when taking it out.Therefore, when performing this work manually, it must be completely stored and until it is completely removed. It must support the weight of the glass plate. For this reason, the insertion / removal work becomes difficult and troublesome. In addition, the glass plate may be damaged due to removal during insertion / removal, and the handling thereof requires extremely careful handling.

On the other hand, since the glass plate cannot be completely fixed only by the positioning groove having a width wider than the thickness of the glass plate, the support is laid across the lateral beams. You will come into contact. Further, during transportation or the like, there is a possibility that the glass plate may slide on the support due to vibration, so that the glass surface may be contaminated or scratched.

For example, when thin glass is used as a substrate, for example, as a glass dry plate for a photomask, it is necessary to prevent other objects from coming into contact with the effective surface of the photomask. A storage device provided with such a support cannot be used. In particular, it cannot be used as a device for storing thin glass after film formation on the glass surface and, if necessary, film removal.

The present invention has been made in view of the above points, and an object thereof is to provide a large number of rectangular thin plates,
The object is to make it possible to store and take out easily while keeping them almost upright and without touching each other or other objects.

[0008]

In order to achieve the above-mentioned object, the present invention comprises a storage box for storing a large number of rectangular thin plates in a state of being inclined at a predetermined angle, and the storage box has a front portion thereof. Can be opened and closed to insert and remove the rectangular thin plate, a glass support wall having cushioning properties is provided on one side surface portion, and the bottom surface portion from the front surface portion to the rear surface portion, A guide groove having a width wider than the thickness of the rectangular thin plate is formed at a constant pitch interval, and a positioning member is provided which is positioned by inserting the lower end of the rectangular thin plate, and the upper end of the rectangular thin plate is provided. A molding member made of an elastic member, which comprises a sandwiching portion which comes into contact with both sides of the rectangular thin plate and a spacer portion which is provided between the sandwiching portions and has a predetermined width, is detachably mounted. The outer width dimension of the spacer portion in a state where the member is attached to the rectangular thin plate is configured to be substantially the same as the total dimension of the width of the guide groove of the positioning member and the width of the ridge portion between the grooves. It is characterized by that.

Here, the material of the rectangular thin plate is transparent,
Substrates and other members that have no defects (dirt, adhesion of foreign matter, scratches, etc.) on the surface such as film formation on the surface regardless of opacity are targeted. For example, a glass dry plate used as a photomask or the like, especially after once forming a film,
Thin glass that has been removed due to foreign matter adhering, etc.
Since the surface is wet, any member should not be brought into contact with the surface, and thus it is particularly preferably used in such a case. However, it goes without saying that the target rectangular thin plate is not limited to this.

The storage box is preferably covered on six sides, and the front part can be opened and closed. An opening / closing door may be provided, or a detachable cover member may be provided using a fastener or the like. The positioning member provided on the bottom plate is preferably divided into two or more parts so as to engage with the lower end of the rectangular thin plate at a plurality of positions in the length direction. Further, it is more preferable that the positioning member is installed on the cushion material in order to absorb the vibration when the rectangular thin plate is inserted or removed or the storage box is moved. The rectangular thin plate is pushed along the guide groove of the positioning member from the front surface side toward the rear surface side. Therefore, it is desirable that the cushion material is also attached to the rear surface of the storage box.

A cushion material is provided on one side surface of the storage box. A molding member detachably attached to the upper end of the rectangular thin plate comes into contact with the cushion material. Then, the inclination angle of the rectangular thin plate at the time of storage is determined by the distance between the surface of the cushion material and the guide groove at the position closest to the side surface of the positioning member. The angle of the rectangular thin plate is closer to the vertical, that is, less than 10 ° from the vertical direction, more preferably about 5 to 3 °. Therefore,
The lower end of the rectangular thin plate is restricted by the right and left rising walls of the guide groove in the retracted state. In particular, it comes into contact with the surface on the side of the inclination, that is, the upper end of the rising wall on the side closer to the side surface where the cushion material is mounted. When the rectangular thin plate has a predetermined area as an effective area and a blank portion having a predetermined width is formed so as to surround the effective area, the mounting portion of the molding member is a blank portion on the upper side of the rectangular thin plate. None, and the depth of the guide groove should be shallower than the width of the lower margin of the rectangular thin plate.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. In the present embodiment, the rectangular thin plate is a rectangular or square thin glass plate, and is used as a storage device used to dry a wet product that has been subjected to a predetermined surface treatment during storage. The configuration will be described as an example. However, the material and the like are not limited to this.

First, FIG. 1 is a front view of the storage device with the front side opened, and FIG. 2 is a sectional view taken along line XX of FIG. 3 is a front view of the storage device shown with the front part closed, and FIG. 4 is a left side view of FIG. In these figures, 1 is a storage box, 2 is a caster provided on the bottom surface of the storage box at 3 to 4 places,
This allows the storage device to be transported.

The storage box 1 is provided with a bottom plate 3, left and right side plates 4, 5, a rear plate 6, and a canopy part 7, and the front part is a front cover 9 which can be opened and closed by fasteners 8, 8. There is. The front cover 9 and the canopy portion 7 are formed as an integral sheet. Therefore, by closing the front cover 9, the internal space of the storage box 1 is closed. A large number of glass plates 10 are stored inside the storage box 1 in a parallel state with an inclination angle close to vertical.

A cushion material 11 is attached on the bottom plate 3, and a positioning member 12 is attached on the cushion material 11. The positioning member 12 is
Consisting of a plate made of synthetic resin having a predetermined width and thickness,
A large number of guide grooves 13 formed at a predetermined pitch interval are formed on the upper surface side of the guide grooves 13.
Penetrates from the front side to the rear side. The positioning members 12 are provided at two positions with a predetermined space in the front-rear direction.

A glass support wall having a cushioning property and preferably made of a low elastic material is attached to the inner surface of the side plate 4. In the illustrated case, the glass support walls are provided at three positions, the upper glass support wall 14U is in contact with a large-sized glass plate, and the middle glass support wall 14M is a medium size. Glass plate abuts on the lower glass support wall 14L.
Is a small glass plate that abuts. Among the three glass support walls 14U, 14M, and 14L, the lower glass support wall 14L has the largest thickness, and the upper glass support wall 14U has the smallest thickness. If only a single size glass plate is to be stored, it is sufficient to provide the glass support wall only at one place, and if the glass support wall is inclined so that the inner surface side is inclined downwardly,
Furthermore, glass plates of different sizes can be stored.

A cushion material 15 is also attached to the rear plate 6, and the cushion material 15 has a height dimension from the bottom plate 3 to at least the position of the glass support wall 14U from the rising portion, and the left and right sides are also provided. It has a width reaching the connecting portion to the side plates 4 and 5. Here, the cushion material 15, the cushion material 11 provided on the bottom plate 3, and the glass support walls 14U, 14M, and 14L can be formed of, for example, styrene foam.

The glass plate 10 is stored in a state of being engaged with the guide groove 13 of the positioning member 12.
A molding member 16 is detachably attached to the upper end portion of 0. As shown in FIG. 5, the molding member 16 is composed of left and right sandwiching portions 17, 17 and a spacer portion 18 provided between the sandwiching portions 17, 17. The molding member 16 is made of an elastic material such as a synthetic resin, and in its free state (the state shown in the upper part of FIG. 5), both the clamping portions 17,
The interval D1 on the opening end side in 17 is slightly larger than the thickness dimension T1 of the glass plate 10, and the width D2 of the narrowest part.
Is smaller than the thickness T1 of the glass plate 10. Therefore, when the molding member 16 is fitted into the upper portion of the glass plate 10 from the opening end side of the holding portions 17 and 17, the narrowest portion is widened so that the upper end edge contacts the inner surface of the spacer portion 18. It will be fitted even in a contact state, and will be stable in the fitted state.

Here, the groove width of the guide groove 13 is B1,
Further, when the width dimension of the ridge portion 12a between the adjacent guide grooves 13, 13 is B2, first, the thickness dimension T1 of the glass plate 10 is slightly smaller than the groove width B1 of the guide groove 13. Due to this dimensional difference, the glass plate 10 is guided by the guide groove 1.
3 can be smoothly inserted. Also, the glass plate 10
In the state where the molding member 16 is fitted to the groove, the most laterally protruding lateral distance T2 of the molding member 16 is defined by the groove width B1 of the guide groove 13 of the positioning member 12 and the width dimension B2 of the ridge portion 12a. The size is almost the same as the total size.

Further, the glass plate 10 is formed with an effective region for exerting a predetermined function, and a margin portion having a predetermined width, that is, a region in which the above-mentioned function is not exerted exists around the effective region. The fitting portion of the molding member 16 and the insertion depth into the guide groove 13 are smaller than the size of the blank portion. Therefore, with respect to both front and back surfaces of the glass plate 10, the margins thereof are in contact with the molding member 16 and the guide groove 13, but the effective region is kept in a state of not contacting any member.

From the thickness of the glass plate 10, the guide groove 13 is formed.
Since the width dimension is larger, when the glass plate 10 is inserted into the guide groove 13, the glass plate 10 is inclined from the vertical state by a predetermined angle according to the gap. Therefore, the tilt angle is slightly tilted from the vertical state to 10 ° or less, more preferably 5 to 3 °. The surfaces of the glass support walls 14U, 14M and 14L are fitted to the upper ends of the glass members 10 in the tilted posture of the glass plate 10 regulated by the guide grooves 13, respectively.
It is arranged at a position where 6 abuts. This allows a large number of glass plates 10 in a compact size storage box.
Can be stored.

Further, as is apparent from FIGS. 3 and 4, in the bottom plate 3, support pipes 19 bent in a substantially U shape are respectively provided at positions outside the side plates 4, 5 and the rear plate 6. Both ends of each of these support pipes 19 are fixed to the bottom plate 2 and are erected in a substantially arch shape. In addition, a plurality of reinforcing crosspieces 20 are vertically installed on the vertical portion of each support pipe 19. Further, a connecting rod 21 is connected to an intermediate portion on one side (left side in FIG. 1) between the support pipes 19 located on the left and right so as to be rotatable in the vertical direction, and the other end of the connecting rod 21. The portion is detachably connected to a locking portion 22 provided on the support pipe 19 on the other side (the right side in FIG. 1).

The present embodiment is configured as described above, and in storing the glass plate 10 in the storage box 1 which constitutes the storage device thereof, first, the front part of the storage box 1 is opened. To do. In other words, open fastener 8,
The front cover 9 is pushed up onto the canopy portion 7, and the connecting rod 21 is held in a suspended state. by this,
The front part of the storage box 1 is completely opened.

On the other hand, a glass plate 10 stored in the storage box 1 (in the following description, a large-sized glass plate,
That is, the molding member 16 is attached to the upper end portion of the glass plate that is stored so as to contact the upper glass support wall 14U. Here, with the glass plate 10 in an upright state, the nipping portion 17 of the molding member 16 from the upper side,
By fitting the openings of 17 into the glass plate 10
The operator's hand or other member can be easily attached to the effective surface of the device without contacting it. In this state, the glass plate 10 is lifted and inserted into the guide groove 13 of the positioning member 12 provided on the bottom plate 3 of the storage box 1. Although a large number of guide grooves 13 are provided, the guide groove that is first inserted is the guide groove located on the leftmost side in FIG. 1, that is, the position closest to the glass support wall 14U. Here, since the positioning member 12 is mounted on the cushion material 11, it is possible to suppress the impact from being applied when the glass plate 10 is engaged with the guide groove 13.

When the glass plate 10 is inserted into the guide groove 13, the glass plate 10 is set upright, and the glass plate 10 is pushed into the storage box 1 until it is completely inserted. Here, since the cushion material 15 is attached to the inner surface of the rear surface plate 6, even if the glass plate 10 is pushed to a position where it comes into contact with the cushion material 15, the glass plate 10 is chipped or damaged. There is no fear of such. Then, in this state, the upper end of the glass plate 10 is tilted so that the molding member 16 mounted on the upper end of the glass plate 10 is brought into contact with the glass support wall 14U. Accordingly, the lower end portion of the glass plate 10 is guided by the guide groove 13.
The molding 16 is supported inside and is also supported so that the molding member 16 attached to the upper end contacts the glass support wall 14U.
Since the effective surface of the glass plate 10 is below the fitting portion of the molding member 16 and above the insertion portion into the guide groove 13, the effective surface of the glass plate 10 is damaged,
There is no risk of being soiled.

When the glass plate 10 is stored, the inclination angle of the glass plate 10 is about 5 to 3 ° with respect to the vertical plane, and the glass plate 10 is in a posture close to the vertical state.
Supported by. On the other hand, since the glass plate 10 is not in a vertical state but slightly tilted toward the glass support wall 14U, the center of gravity of the glass plate 10 is located at a position deviated from the vertical line to the glass support wall 14U side. The glass plate 10 is supported, and only the upper and lower ends of the glass plate 10 are supported and stably held in this posture. When the tilt angle of the glass plate 10 during storage is increased, the center of gravity is greatly deviated by that amount. As a result, the glass plate 10 receives the load in the direction in which the middle portion bends with the upper and lower ends as fulcrums,
In extreme cases, the glass may crack. However, if the tilt angle is about 5 to 3 °,
Since the shift amount of the position of the center of gravity is suppressed to the minimum, there is no fear that an unreasonable load acts on the glass plate 10.

Next, when the second glass plate 10 is stored, as shown in FIG. 6, the glass plate 1 previously stored is stored.
It is inserted in the guide groove 13 next to the guide groove 13 in which 0 is inserted. Then, when the glass plate 10 is inserted to a predetermined position, the molding member 16 is tilted so as to abut on the side portion of the molding member 16 mounted on the glass plate 10 previously inserted. Here, the outer spacing T2 of the molding member 16 is equal to the guide groove 1 of the positioning member 12.
Since the total width of the groove width B1 of No. 3 and the width dimension B2 of the ridge portion 12a is almost the same, the second glass plate 10 is arranged substantially parallel to the first glass plate 10, that is, the molding member. 16 contact each other, and the surfaces of both glass plates 10, 10 are reliably kept in a non-contact state.

As described above, the glass plates 10 are sequentially inserted from the guide groove 13 on the left side of FIG. 1 and the upper end portion is tilted leftward so that a predetermined number of glass plates 10 are stored in the storage box 1. Is stored. When the storage of the predetermined number of glass plates 10 is completed, the front cover 9 is pulled down, and the fasteners 8 on both sides of the front cover 9 are closed, so that the storage box 1 is closed and the internal atmosphere is kept substantially constant. Be drunk Then, the connecting rod 21 is rotated upward to lock the tip end thereof to the locking portion 22. Further, if necessary, in order to prevent the glass plate 10 from protruding toward the front cover 9, a glass pressing member such as the belt 23 may be attached to the outer surface of the front cover 9.

Here, when the surface of the glass plate 10 is wet, the liquid flows down along the surface of the glass plate 10 and is removed. The liquid that has flowed down is in the guide groove 1 of the positioning member 12.
However, since the width of the positioning member 12 is relatively short, it can be easily discharged from both sides of the positioning member 12. In addition, if the guide groove 13 is inclined so that the central portion is highest and becomes lower toward both ends, the liquid can be discharged more smoothly.

Glass plate 10 stored in storage box 1
The casters 2 are provided in the lower part of the storage box 1 for transporting between the processes.
By pulling the connecting rod 21 suspended between 9 and 19, it can be easily transported to a predetermined position. Even if some vibration occurs during this conveyance, the positioning member 12 that bears most of the load of the glass plate 10 stored in the predetermined number is provided on the cushion material 11, so that the positioning member 12 receives the vibration. The transmission of the glass plate 10 can be suppressed, and since each glass plate 10 is held in the inclined state, the glass plate 10 is held in an extremely stable state and does not move unintentionally or come into contact with other members.

Then, from the storage box 1 to the glass plate 10
To take out, the connecting rod 21 is removed from the locking portion 22, the fastener 8 is opened, and the front cover 9 is lifted. As a result, the glass plate 10 can be taken out by pulling it toward you. The glass plates 10 are sequentially taken out from the last stored glass plate 10 during storage. That is, the glass plate 10 located on the rightmost side in FIG. 1 is stood upright and pulled out, so that the glass plate 10 can be easily taken out.

Here, since the molding member 16 is mounted on at least the upper end portion of the glass plate 10 when the operator stores and takes out the glass plate 10, this molding member 16 is used.
Can be touched. Therefore, when the glass plate 10 is manually raised or tilted, by holding the molding member 16, it is possible to easily perform the operation without touching the glass plate 10. Moreover, most of the load of the glass plate 10 is stored from the time when the front end of the glass plate 10 is engaged with the guide groove 13 at the time of storage, to the time when the front end of the glass plate 10 is completely removed from the guide groove 13 at the time of removal. Since it can be received in the box 1, the glass plate 10 can be stored and taken out easily and safely.
