Description

  The present invention relates to a glass plate storage jig for storing a glass plate, for example, when performing a cleaning process of the glass plate.

  As well known, recently, with the development of electronic devices etc., substrates of flat panel displays (FPDs) and sensors such as liquid crystal displays, plasma displays, field emission displays (including surface emission displays) and electroluminescent displays, Alternatively, a wide variety of glass products such as covers for semiconductor packages such as solid-state imaging devices and laser diodes, and substrates for thin film compound solar cells are used. And although thinning is advanced in various kinds of glass plates, as such a situation progresses, a glass plate comes to have flexibility from its thinness.

  On the other hand, not only for glass plates, but also for plate-like bodies, for example, jigs that collectively accommodate a plurality of plate-like bodies are used in order to improve the working efficiency at the time of processing such as washing and drying or at the time of transportation. Ru. In such a housing jig, usually, a plurality of glass plates are housed in a longitudinal orientation and arranged in the thickness direction so as to form a gap therebetween, and the plurality of glass plates are respectively supported from both sides A lateral support groove and a lower support groove for supporting a plurality of glass plates from below are provided (for example, Patent Document 1).

Japanese Utility Model Application Publication No. 4-48540

  However, a flexible plate-like body such as the above-described laminated glass plate is flat due to its flexibility during processing and transportation while being accommodated in such a jig. It is difficult to maintain a good shape. As a result, adjacent glass plates come into contact with each other, causing problems such as scratching or breakage of the glass plates.

  From such a point of view, a first object of the present invention is to suppress contact between a plurality of glass plates accommodated in a glass plate accommodation jig.

  In addition, when the plate-like body such as a glass plate is housed in the jig as described above, when it is pulled up from the washing tank after washing, the washing liquid (for example, water etc.) is around the contact portion with the jig. It may remain, and due to this, it may not be possible to dry sufficiently.

  From such a point of view, a second object of the present invention is to facilitate drying after cleaning the glass plate accommodated in the glass plate accommodation jig.

  The glass plate accommodation jig of the present invention, which was invented to solve the first problem, accommodates a plurality of glass plates arranged in the thickness direction so as to form a gap therebetween in the vertical posture. A lateral support formed with a lateral support groove for supporting the plurality of glass plates from both sides, and a lower support having a lower support groove formed to support the plurality of glass plates from below. And a flexible strip disposed along the main surface of the glass plate in a gap between the plurality of glass plates. Here, the term "flexible strip" includes, in addition to threads, cords, bands, wires, etc., plastic rods, piano wires, straws, etc. (the same applies hereinafter).

  According to such a configuration, even if the glass plate can not maintain a flat shape due to the flexibility during processing and transportation of the plurality of glass plates housed in the jig, the glass plates By means of the flexible strips arranged in the gaps between them, the unfair deformation of the glass sheet is suppressed. Thereby, the situation where a plurality of glass plates stored in the jig concerned mutually contact is prevented, and problems, such as contact damage being attached to a glass plate, are avoided. Further, since the strip is flexible, the strip can deform following the deformation of the glass plate even if the glass plate is deformed, so that the glass plate is caused by the contact between the glass plate and the strip. Is less likely to be damaged. The hardness of the flexible strip is preferably lower than the hardness of the glass plate.

  In the above-mentioned configuration, it is preferable that the flexible strips are disposed so as to pass through a gap between central regions of opposing main surfaces of adjacent glass plates.

  Since the central region of the main surface of the glass sheet is the area farthest from the portion of the supported peripheral edge, a large deflection occurs and the adjacent glass sheets are likely to be in contact with each other. Therefore, when the flexible strip passes through the gap between the two corresponding to the central region, the contact between the glass plates can be efficiently suppressed.

  In the above configuration, it is preferable that a pair of the flexible strips intersect at a gap between the central regions.

  With this method of arranging the flexible strip, contact between central regions of the main surfaces of the glass plate can be more reliably and efficiently suppressed by the flexible strip.

  In the above configuration, the thickness of the glass plate is preferably less than 200 μm.

  If the thickness of the glass plate is less than 200 μm, the flexibility of the glass plate becomes remarkable, and the possibility of contact between the glass plates increases, so the above-described configuration becomes more effective.

  In the above configuration, it is preferable that the cross-sectional shape of the side support groove is V-shaped, and the cross-sectional shape of the lower support groove is U-shaped.

  If the cross-sectional shape of the side support groove is V-shaped, the glass plate can be supported more reliably from both sides without rattling, and when the jig is pulled up from the cleaning tank, the glass plate and the side The cleaning liquid between the support grooves is unlikely to drop and remain due to its own weight. Moreover, if the cross-sectional shape of the lower support groove is a U-shape, it can suppress that a washing | cleaning liquid remains between a glass plate and a lower support groove, when pulling up from a washing tank. As a result of the above, after securing stable support of the glass plate, drying of the glass plate after cleaning becomes easy.

  The glass plate accommodation jig of the present invention, which was invented to solve the second problem, accommodates a plurality of glass plates arranged in the thickness direction such that a gap is formed between them in the vertical posture. A lateral support formed with a lateral support groove for supporting the plurality of glass plates from both sides, and a lower support having a lower support groove formed to support the plurality of glass plates from below. The cross section of the side support groove is V-shaped, and the cross-sectional shape of the lower support groove is U-shaped.

  According to such a configuration, since the cross-sectional shape of the lower support groove is U-shaped, it is possible to suppress that the cleaning liquid remains between the glass plate and the lower support groove when pulled up from the cleaning tank. In addition, since the cross-sectional shape of the side support groove is V-shaped, the glass plate can be supported more reliably from both sides without rattling, and when the jig is pulled up from the cleaning tank, the glass plate The cleaning liquid between the side support grooves falls by its own weight and hardly remains. As a result of the above, after securing stable support of the glass plate, drying of the glass plate after cleaning becomes easy.

  As mentioned above, according to the present invention, contact between a plurality of glass plates accommodated in a glass plate accommodation jig can be controlled.

  Further, according to the present invention, it is possible to facilitate drying after cleaning the glass plate housed in the glass plate housing jig.

  Examples of the material of the side support rods 5, the lower support rods 6, and the upper support rods 7 include synthetic resins such as Teflon (registered trademark), polyether ethyl ketone (PEEK), polyimide resin, and MC nylon (registered trademark). It can be mentioned.

  Further, in the present embodiment, as shown in FIGS. 5 and 7, metal shafts 5 c and 6 c are inserted into and fixed to central portions of the side support rods 5 and the lower support rods 6. The end portions of the shafts 5 c and 6 c are inserted into the through holes 4 a of the plate 4 and are detachably attached to the plate 4. Therefore, it is possible to change the arrangement of the side support rods 5 and the lower support rods 6 by changing the mounting positions of the end portions of the shafts 5c, 6c in accordance with the dimensions of the glass plate 2. Furthermore, it is also possible to change the number of rows of the glass sheets 2 by changing the arrangement of the side support rods 5 and the lower support rods 6. Further, the upper support rod 7 is fixed to a metal attachment member (not shown), and the attachment member is detachably attached to the frame 3 so that the upper support rod 7 can be attached to and detached from the frame 3 It has become.

  As shown in an enlarged manner in FIG. 6, the cross-sectional shape of the side support groove 5a is V-shaped. The angle α of the V shape of the cross-sectional shape in the side support groove 5a is preferably 6 ° to 26 °, for example. If the angle α of the V-shape is less than 6 °, the glass plate 2 can not be sufficiently inserted into the side support groove 5a, and the insertion operation may become difficult. If the angle α of the V-shape exceeds 26 °, the glass plate 2 may not be sufficiently supported, and the glass plate 2 may be unduly bent. Moreover, the width of the side support groove 5a becomes large, the side support groove 5a which can be formed in the side support rod 5 of the same length decreases, and the glass plate 2 which can be accommodated in the glass plate accommodation jig 1 of the same dimension. Decreases. From these viewpoints, the V-shaped angle α is more preferably 8 ° to 24 °, and most preferably 10 ° to 22 °.

  Moreover, as for the depth d1 of the side support groove 5a, 14 mm-26 mm are preferable, for example. If the depth d1 is less than 14 mm, the glass plate 2 can not be sufficiently inserted into the side support groove 5a, and the glass plate 2 may come off. If the depth d1 exceeds 26 mm, drying after washing may be insufficient. From these viewpoints, the depth d1 of the side support groove 5a is more preferably 16 mm to 24 mm, and most preferably 18 mm to 22 mm.

  As shown in FIG. 2, in the upper support rod 7, a plurality of linear upper support grooves 7 a are provided at lower portions at predetermined intervals in the longitudinal direction. The sectional shape of the upper support groove 7a is also V-shaped. The angle of the V-shaped cross section of the upper support groove 7a and the depth of the upper support groove 7a are the same as in the case of the side support groove 5a.

  As shown enlarged in FIG. 8, the cross-sectional shape of the lower support groove 6 a is a U-shape. In the present embodiment, the lower portion (the cross-sectional shape of the bottom of the lower support groove 6a) of the U shape of the cross-sectional shape of the lower support groove 6a is a partially circular arc of a perfect circle, but is not limited thereto. It may be a smooth curved shape in which the depth gradually becomes deeper toward the center. The radius of the partially arcuate portion of the U-shaped cross section in the lower support groove 6a is preferably, for example, 1.9 mm to 3.1 mm. If the radius is less than 1.9 mm, the cleaning solution may remain between the glass plate 2 and the groove bottom after cleaning, resulting in insufficient drying. If the radius exceeds 3.1 mm, the glass plate 2 can not be sufficiently supported, and the glass plate 2 may be bent unduly. From these viewpoints, the radius of the partial arc-shaped portion of the U-shaped cross section in the lower support groove 6a is more preferably 2.1 mm to 2.9 mm, and most preferably 2.3 mm to 2.7 mm.

  The depth d2 of the lower support groove 6a is preferably, for example, 14 mm to 26 mm. If the depth d2 is less than 14 mm, the glass plate 2 can not be sufficiently inserted into the lower support groove 6a, and the glass plate 2 may come out. If the depth d2 exceeds 26 mm, drying after washing may be insufficient. From these viewpoints, the depth d2 of the lower support groove 6a is more preferably 16 mm to 24 mm, and most preferably 18 mm to 22 mm.

  The width w of the lower support groove 6a is preferably, for example, 2 mm to 6 mm. If the width w is less than 2 mm, the cleaning solution tends to remain between the glass plate 2 and the side surface of the lower support groove 6a after cleaning, which may result in insufficient drying. If the width w exceeds 6 mm, the glass plate 2 can not be sufficiently supported, and the glass plate 2 may be bent unduly. Further, the lower support groove 6a which can be formed in the lower support rod 6 of the same length is reduced, and the glass plate 2 which can be accommodated in the glass plate accommodation jig 1 of the same dimension is reduced. From these viewpoints, the width w of the lower support groove 6a is more preferably 2.5 mm to 5 mm, and most preferably 3 mm to 4 mm.

  As shown in FIGS. 6 and 8 in an enlarged manner, the lateral locking groove 5b and the lower locking groove 6b have the same shape and the same size, and the cross-sectional shape is V-shaped. The angle β of the V shape of the cross-sectional shape of the side locking groove 5b and the lower locking groove 6b is preferably, for example, 24 ° to 36 °. If the angle β of the V is less than 24 °, not only the flexible strip 8 is not sufficiently inserted, but also the insertion operation may be difficult. If the angle β of the V is greater than 36 °, the flexible strip 8 may be displaced during use. The V-shaped angle β is more preferably 26 ° to 34 °, and most preferably 28 ° to 32 ° from these viewpoints.

  Next, the usage method of the glass plate accommodation jig 1 of this embodiment is demonstrated.

  First, before arranging the glass plates 2 in the glass plate accommodation jig 1, the attachment member (not shown) to which the upper support bar 7 is fixed is removed from the frame 3 of the glass plate accommodation jig 1. ing. Next, the plurality of glass plates 2 are arranged in the glass plate accommodation jig 1. That is, the plurality of glass plates 2 are inserted in the vertical posture into the glass plate accommodation jig 1.

  After arranging all the glass plates 2 in the glass plate accommodation jig 1, the mounting member to which the upper support bar 7 is fixed is attached to the frame 3. Installation of the glass plate 2 to the glass plate accommodation jig 1 is now completed.

  In this state, the glass plate housing jig 1 is immersed in the cleaning solution in the cleaning tank to clean the glass plate 2. Thereafter, the glass plate accommodation jig 1 is pulled up from the cleaning tank, and the cleaning liquid adhering to the glass plate accommodation jig 1 and the glass plate 2 is dried by the drying device.

  Then, the glass plate 2 is taken out from the glass plate accommodation jig 1 in the reverse procedure to the above. That is, the attachment member to which the upper support rod 7 is fixed is removed from the frame 3, and the glass plate 2 is taken out from the glass plate accommodation jig 1.

  The glass plate accommodation jig 1 of the present embodiment configured as described above can receive the following effects.

  Even if the glass plate 2 can not maintain a flat shape due to the flexibility during processing and transportation of the plurality of glass plates 2 accommodated in the glass plate accommodation jig 1, By means of the flexible strips 8 arranged in the gaps, the unfair deformation of the glass sheet 2 is suppressed. Thereby, the situation where the several glass plate 2 accommodated in the glass plate accommodation jig 1 mutually contacts is prevented, and malfunctions, such as a contact flaw being attached to the glass plate 2, are avoided. Further, since the strip 8 is flexible, even if the glass plate 2 is deformed, the strip 8 can be deformed following the deformation of the glass plate 2 so that the contact between the glass plate 2 and the strip 8 The possibility of the glass plate 2 being damaged due to The hardness of the flexible strip 8 is preferably lower than the hardness of the glass plate 2.

  In addition, since the outer diameter of the flexible strip 8 is small, the flexible strip 8 can be wound or tied and fixed. Attachment and detachment of the body 8 are easy. Thereby, it is easy to change the method of arrangement of the flexible strip 8 along with the change of the dimension of the glass plate 2 or the like.

  Further, as shown in FIG. 8, since the cross-sectional shape of the lower support groove 6a in the glass plate housing jig 1 is U-shaped, when pulled up from the cleaning tank, the glass plate 2 and the lower support groove 6a shown by a two-dot chain line. It is possible to suppress the remaining of the cleaning liquid in the meantime. That is, if the lower support groove 6a is temporarily V-shaped similarly to the side support groove 5a, the cleaning solution remains between the glass plate 2 and the lower support groove 6a. However, in the present embodiment, since the lower support groove 6a has a U-shaped cross section, such a problem does not occur. This facilitates drying of the glass plate 2 after cleaning.

  Further, as shown in FIG. 6, since the cross-sectional shape of the side support groove 5a is V-shaped, the glass plate 2 shown by the two-dot chain line can be supported from both sides more reliably without causing rattling. In this case, even if the cross-sectional shape of the side support groove 5a is V-shaped, the cleaning liquid between the glass plate 2 and the side support groove 5a falls by its own weight, and is not affected by the capillary phenomenon. As a result of the above, after securing stable support of the glass plate 2, drying of the glass plate 2 after cleaning becomes easy.

  The present invention is not limited to the above description, and various modifications can be made within the scope of the technical idea thereof. For example, in the said embodiment, although the flexible strip was hung on the support rod which supports a glass plate, you may be hung on frames other than a support rod, or another member.
