Description
- 1. Field of the Invention
- The present invention relates to a wrapping member for a glass substrate used for the production of a FPD (a Flat Panel Display) such as a liquid crystal display and a plasma display, and relates to a transferring method of a glass substrate for FPD. More, particularly, the present invention relates to a wrapping member for a glass substrate for FPD in which by wrapping the glass substrate or substrates with a water-soluble film, processing of the glass substrates and the wrapping member in the production line of FPDs can be simplified as well as reducing of the outer appearance dimension of the transferred packages can be accomplished thereby making it possible to transfer the glass substrates at a high efficiency, and to a method of transferring the glass substrates for FPD.
- 2. Description of the Related Art
- Hitherto, in transfer of glass substrates used for the production of FPDs such as a liquid crystal display and a plasma display, a transfer box as shown in
FIG. 6 has been employed. This transfer box 1 is produced so as to contain therein a plurality of glass substrates arranged to maintain their standing positions, and consists of a box-like body portion 2 made of light-weight and strong material such as polypropylene foam and alid member 3 for covering the opening of thebody portion 2 which are brought into a fixed condition by two rubber orgum bands 4. On the left and right side faces of the interior of thebody portion 2,cushion members 6 for fixedly keeping theglass substrates 5 for FPD by sandwiching the marginal portions of the substrates are arranged as shown inFIG. 7 . On the inside face of thecushion member 6, a plurality of protrudingportions 7 are formed as shown in a partial enlarged view “P” ofFIG. 7 , and between every twoprotruding portions gaps 8, each having the width thereof corresponding to the thickness of theglass substrate 5, have been formed. In agap 8 formed between the every adjacent twoprotruding portions glass substrate 5 is fitted in such a manner that the margin of theglass substrate 5 is fixedly sandwiched by the adjacent twoprotruding portions glass substrates 5 is stored and juxtaposed in the interior of the transfer box 1 while being held in a vertically standing position, respectively. The above-described transferring method is typically disclosed in Japanese Unexamined (Kokai) Patent Publication No. 7-285611. - Nevertheless, the described transfer box 1 with the
respective gaps 8 for fixedly fitting theglass substrates 5 must have suffered from an inconvenience as described below. That is to say, in order to prevent theglass substrates 5 from being damaged due to mutual contact of the neighboring glass substrates if theglass substrates 5 were subjected to bending during the transfer of the box 1 with theglass substrates 5 stored therein,respective gaps 8 of the transfer box 1 should be formed and arranged to define a predetermined distance “g0” between the two neighboringgaps 8 when it is measured at the centers thereof, as shown in a partial enlarged view “P” ofFIG. 7 . For example, when theglass substrates 5, each of which is dimensioned to have 1100 mm width×1300 mm height and a thickness equal to or less than 1 mm, theprotruding portions 7 must have been formed so that the distance “g0” between the neighboringgaps 8 is approximately 25 mm. Therefore, as shown inFIG. 6 , when the transfer box 1 is provided to store therein 20 sheets ofglass substrates 5 for FPD, the outer dimension of the transfer box 1 is approximately 1200 mm width×1410 mm height×720 mm depth and, accordingly the entire size of the transfer box 1 could be a considerable large. - On the other hand, in recent years, as a glass substrate for producing a FPD having a large screen, there has been provided a glass substrate having for example, 1300 mm width×1500 mm height, 1500 mm width×1800 mm height, or 1900 mm width×2100 mm height. Nevertheless, the larger is the size of the glass substrate, the greater must be the bending of the glass substrate. Thus, to prevent the
glass substrates 5 juxtaposed in the transfer box 1 from coming in contact with one another, the distance g0 between the neighboringgaps 8 must be further increased, and therefore the depth “D” of the transfer box 1 must be increased. Namely, the volume of the transfer box 1 must be increased depending on an increase in the size of theglass substrate 5 and accordingly, the outer size of the transfer box 1 must be larger resulting in making it difficult to obtain an increased efficiency in the transfer of the transfer box 1 with the glass substrates therein. - In this connection, as a method of reducing the outer size of the glass substrates for FPD after they are completely wrapped by the wrapping material, there has been provided a method in which, as shown in (A) of
FIG. 8 , a thinplastic film 9 is interposed between every two of theglass substrates 5 as a spacer for protecting the surface of eachglass substrate 5 before theglass substrates 5 are packed. However, in this method, a specified process for taking every one of theglass substrate 5 out of the stack of theglass substrates 5, as shown in (B) ofFIG. 8 and for removing each thinplastic film 9 from the surface of theglass substrate 5, as shown in (C) ofFIG. 8 has been required during processing of theglass substrates 5 on the production line for producing the FPD. Further, during removing of the thinplastic film 9 by peeling, static electricity might occur causing attaching of fine and minuteforeign matters 10 such as dust on the surface of theglass substrate 5, as shown in (D) ofFIG. 8 and therefore, a lot of time have been often needed for cleaning theglass substrate 5. Moreover, after heeling of the thinplastic film 9 from the surface of theglass substrate 5, there might have often occurred thatadhesive 11 is left on the surface of theglass substrate 5 as shown in (D) ofFIG. 8 . Therefore, in such case, it has been needed to completely remove suchresidual adhesive 11 from the surface of theglass substrate 5, which renders a pretreatment process of theglass substrate 5 for FPD rather cumbersome. In addition, since theplastic films 9 removed from the surface ofrespective glass substrates 5 during the step shown in (C) ofFIG. 8 must have been legally property disposed as industrial wastes, additional time and expense must have been spent for the waste disposal. - Therefore, to overcome the above-described problems encountered by the conventional art, an object of the present invention is to provide a wrapping member for a glass substrate for FPD, which enables it to simplify the processing of the glass substrates and the wrapping member on the production line of the FPD, and to reduce the outer size of the wrapped glass substrates thereby allowing the glass substrates to be transferred at a high efficiency.
- Another object of the present invention is to provide a method of carrying out such a highly efficient transfer of the glass substrates for FPDs.
- To achieve the above objects, in accordance with one aspect of the present invention, there is provided a wrapping member for a glass substrate for FPD, which wraps either one or both of the surfaces of the glass substrate for use in production of a FPD in a form suitable for being transferred, and is characterized in that the wrapping member is made of a material, which comprises a water-soluble film able to be dissolved in water.
- Due to the above-described constitution of the present invention, the wrapping member used for wrapping the glass substrate for FPD can be dissolved in the water without becoming industrial wastes. Therefore, wrapping of the glass substrate with the water-soluble film can simplify the processing of respective glass substrates and the wrapping member on the production line of the FPD and additionally, reduce the outer size of the glass substrate in its wrapped condition for transfer thereby allowing the wrapped glass substrate to be transferred at a high transferring efficiency.
- The above water-soluble film may be made of denatured polyvinyl alcohol. Owing to this, it is possible to adjustably change a temperature at which the water-soluble film is dissolved and the solving speed of the water-soluble film, depending on the mode of use of the water-soluble film and accordingly, dissolving condition of the water-soluble film may be freely selected as required. Therefore, the processing of the glass substrate and the wrapping member conducted on the production line of the FPD can be simplified.
- The method of transferring glass substrates for FPD in accordance with another aspect of the present invention is characterized by comprising the steps of:
- laminating a water-soluble film soluble in water onto either one or both of surfaces of each of the glass substrates;
- admitting the glass substrates in a transfer box via an open end thereof to be stored therein in a manner such that they are superposed on each other; and
- covering the open end of the transfer box with a lid to form a packed transfer box with the glass substrates stored therein, so that the packed transfer box is subjected to a transferring process.
- When the above-mentioned method is carried out, either one or both of the surfaces of each glass substrate for FPD is laminated with the water-soluble film, and a plurality of the glass substrates, each being laminated with the water-soluble film, is stored in the transfer box in a condition such that they are superposed one another. Then, the transfer box is closed by covering the open end of the transfer box with the lid so as to form a packed transfer box with the glass substrates stored therein, and the packed transfer box is subjected to the transferring process. Owing to this method, the outer size of the packed transfer box can be small enough for being transferred at a high transferring efficiency.
- Further, the above-mentioned transfer box and the lid are preferably made of material having hydroscopic property. Owing to this hydroscopic property of the material of the transfer box and the lid, the transfer box together with the lid may absorb the humidity in the atmosphere, so that solving of the water-soluble film may be prevented. Accordingly, during transferring of the glass substrates in the transfer box, the glass substrates can be always kept in a condition where the glass substrates within the transfer box are prevented from coming in contact with one another and therefore the surfaces of the glass substrates may be protected against damage.
- Further, the transfer box and/or the lid may be provided with drying agent or desiccant in the inside thereof. Thus, any humidity contained within the transfer box and the lid may be absorbed by the drying agent or the desiccant, so that solving of the water-soluble film during the transferring of the glass substrates in the transfer box may be prevented. Therefore, during transferring of the glass substrates in the transfer box, the glass substrates can be always kept in a condition where the glass substrates within the transfer box are prevented from coming in contact with one another and therefore the surfaces of the glass substrates may be protected against damage.

FIG. 8 is a schematic and explanatory view of the processing steps, in which (A) through (D) illustrate how the steps for processing the glass substrates wrapped with the wrapping member according to the prior art are conducted in the production line of the FPD. - Referring to
FIG. 1 , which illustrates atransfer box 12 with alid 13 covering an open end of thebox 12, a plurality ofglass substrates 5 for FPDs are stored and packed in thetransfer box 12 covered by thelid 13, by the employment of a wrapping member according to the present invention. The wrappingmembers 14 are respectively provided as a thin film for protecting the surfaces of each theglass substrates 5 for FPD, and as shown in a partially enlarged view “Q” ofFIG. 1 , onewrapping member 14 is interposed between the respective upper andlower glass substrates 5 superposed one another. Owing to this interposition of the wrappingmembers 14, without using of the transfer box 1 of the prior art as shown inFIG. 6 , a plurality ofglass substrates 5 for FPD may be stored in the interior of thetransfer box 12 and thelid 13 as shown inFIG. 1 , and can be transferred. Since thetransfer box 12 and thelid 13 may have a capacity thereof sufficient for storing a plurality ofglass substrates 5 placed to be superposed one another, the outer dimension of thetransfer box 12 and thelid 13 after packing up thesuperposed glass substrates 5, particularly, the height “h” of the package formed of thetransfer box 12 and thelid 13 mated together for containing therein theglass substrates 5 can be prevented from becoming unexpectedly large. Thus, even when theglass substrates 5 having large sizes such as, for example, 1300 mm width×1500 mm height, 1500 mm width×1800 mm height, and 1900 mm width×2100 mm height, are to be transferred, the height “h” of the package obtained from packing any of suchlarge glass substrates 5 by the use of thetransfer box 12 and thelid 13 does not cause any appreciable change. Therefore, the transfer of theglass substrates 5 for FPD can be carried out at a high efficiency. - At this stage, in the present invention, the above-mentioned
wrapping member 14 is made of a water-soluble material, i.e., a water-soluble film that can be dissolved in water. The water-soluble film 14 is a membrane material made of denatured polyvinyl alcohol and therefore, it is possible to adjust dissolving condition of the water-soluble film 14 depending on a change in the mode in which thefilm 14 is used. Namely, since the dissolving speed of the water-soluble film 14 changes in response to a change in the water temperature, the thickness of thefilm 14, and dissolving method adopted, any arbitrary dissolving condition can be selectively set as required. Thus, theglass substrates 5 transferred as a package packed by thetransfer box 12 and thelid 13, and the water-soluble film 14 as the wrapping member can be simply processed on the production line of the FPD. Namely, from a plurality ofglass substrates 5 as shown in (A) ofFIG. 2 , every sheet ofglass substrate 5 in a state where the water-soluble film 14 is attached to the surface thereof as shown in (B) ofFIG. 2 is withdrawn one after another. Subsequently, every drawnglass substrate 5 is in succession immersed in water held in awater vessel 15 as shown in (C) ofFIG. 2 . As a result, the water-soluble film 14 is dissolved in thewater vessel 15 by the time lapse of less than several tens of seconds. For example, when the water-soluble film 14 having 20 micrometers thick is immersed in water at 20° C., the water-soluble film 14 can be dissolved in a time equal to or less than 20 seconds. Then, as shown in (D) ofFIG. 2 , theglass substrate 5 having no water-soluble film 14 left is taken out of thewater vessel 15 so as to be transferred to the next processing stage. Therefore, differing from the conventional case as shown in (A) through (D) ofFIG. 8 where theglass substrate 5 was protected by wrapping with theplastic film 9 according to the prior art, no process for removing the spacer by peeling is required. - Therefore, the preprocessing of the
glass substrates 5 and the processing of the water-soluble film 14 can be simplified. Moreover, since the water-soluble film 14 different from theconventional plastic film 9 is excellent in its hydrophilicity, it cannot be electrified by static electricity. Accordingly, any dust and other foreign matters such as paper powder and the like does not attach to the surface of theglass substrate 5 and thus, the preprocessing of theglass substrate 5 can be prevented from becoming cumbersome. Further, since only preparation of thewater vessel 15 for dissolving the water-soluble film 114 is required, and since no device or apparatus for removing the spacer is required, it is possible to curtail expense for the facility investment necessary for processing theglass substrates 5. Furthermore, the water-soluble film 14 is finally dissolved in water to be separated into carbon dioxide and water, and therefore generation of industrial wastes can be suppressed. Since the water-soluble film 14 does not contain therein any halogen element such as chlorine, it can be wasted with reduced adverse affect on the global environment in comparison with the employment of the ordinary plastic film. - The water-
soluble film 14 described in the foregoing may be embodied by, for example, a product manufactured and sold under the name of “Hi-Selon: the registered trademark in Japan” by the Nippon Synthetic Chemical Industry Co., Ltd. that is one of the chemical industries in Japan. It should be noted that the water-soluble film 14 exhibits excellent properties as a wrapping material such as good mechanical properties including an excellent initial coefficient of elasticity, and an improved tensile strength and stretchability, and a heat-seal strength. Further, since the water-soluble film 14 can be easily either severed mechanically or cut by melting, it can be easily laminated onto the surface of each of theglass substrates 5 Now, the description of a method of transferring a plurality ofglass substrates 5 packaged in the interior of thetransfer box 12 and thelid 13 by the employment of the above-described water-soluble 14 will be provided hereinbelow with reference to the illustration ofFIG. 3 . - Referring first to (A) of
FIG. 3 , the water-soluble film 14 is placed in the form of a roll wounded around acore member 16 in a condition where a rear face of thefilm 14 is coated with a hot-melt type adhesive. The hot-melt type adhesive should preferably be excellent in a dispersing faculty into water and dissolving faculty in water and desirably, those disclosed in e.g., Japanese Unexamined (Kokai) Patent Publication No. 5-4853 and Japanese Unexamined (Kokai) Patent Publication No. 2002-173655 could be used. It should be understood that this type of adhesive having excellent dissolving faculty in water can be easily dissolved in thewater vessel 15 shown in (C) ofFIG. 2 during dissolving of the water-soluble film 14 within thesame water vessel 15, and therefore the adhesive is not left to form no undesirable residue on the surface of theglass substrate 5 when theglass substrate 5 is taken out of thewater vessel 15. As a result, the preprocessing step of theglass substrates 5 on the production line of the FPD can be simplified. - Then, the roll of the water-
soluble film 14 as shown in (A) ofFIG. 3 is rotated in a direction indicated by an arrow “A” so that an extreme end of the water-soluble film 14 is fed and delivered in a direction indicated by an arrow “B” until it is superposed on the upper surface of theglass substrate 5 for FPD from the leading to trailing ends of theglass substrate 5. Subsequently, the water-soluble film 14 together with theglass substrate 5 are supplied so as to be sandwiched betweenheating rollers heating rollers soluble film 14 and theglass substrate 5, and as a result, the adhesive coated on the rear face of the water-soluble film 14 melts thereby permitting the water-soluble film 14 to adhere onto the upper surface of theglass substrate 5. The water-soluble film 14 is then cut at the trailing end of theglass substrate 5 so that thefilm 14 is laminated on the upper surface of theglass substrate 5 as shown in (B) ofFIG. 2 . - Subsequently, the
glass substrates 5 for FPD laminated with the water-soluble film 14, respectively, are placed in succession in the interior of thetransfer box 12 in a condition such that they are superposed on one another within thetransfer box 12 as shown in (C) ofFIG. 3 . As shown in (D) ofFIG. 3 , when a predetermined number of theglass substrates 5 are stored in the superposed condition, thetransfer box 12 is covered with thelid 13 to form a package in which a predetermined number ofglass substrates 5 are packaged within thetransfer box 12 and thelid 13 as shown inFIG. 1 . The package thusly formed to contain therein the predetermined number of theglass substrates 5 is transferred from a given position to another given position. - It should here be understood that the
transfer box 12 and thelid 13 as shown inFIG. 1 and (D) ofFIG. 3 are desirably made of a material having appreciably high hygroscopicity such as cardboard, polypropylene foam, and wood. Thus, as thetransfer box 12 and thelid 13 can absorb the moisture component in the air, any dissolving of the water-soluble film 14 can be prevented during transferring of the package. This fact ensures that theglass substrates 5 for FPD in the package of thetransfer box 12 and thelid 13 are kept in a state where any direct contact of theglass substrates 5 within the package can be prevented during transferring of the package, and the surfaces of therespective glass substrates 5 for FPD are protected against damage. - Further, as shown in a partial enlarged view “Q” of
FIG. 1 , the inside wall of thetransfer box 12 may be provided with asuitable desiccant 19 in the form of a sheet. Thus, thedesiccant 19 can absorb any moisture component in the interior of thetransfer box 12 and thelid 13, so that the water-soluble film 14 can be prevented from being dissolved during transferring of theglass substrates 5. This fact again ensures that theglass substrates 5 for FPD in the package of thetransfer box 12 and thelid 13 are kept in a state where any direct contact of theglass substrates 5 within the package can be prevented during transferring of the package, and the surfaces of therespective glass substrates 5 for FPD are protected from being damaged. Of course, the desiccant provided for thetransfer box 12 and thelid 13 may have any suitable form if it could successfully absorb the moisture component within thetransfer box 12 and thelid 13. - According to the foregoing description, an explanation of the embodiment was provided in which the water-
soluble film 14 functioning as a spacer member is laminated onto the upper surfaces ofrespective glass substrates 5. However, the present invention should not be limited to only such embodiment, and therefore the water-soluble film 14 may be embodied to be applied to both the upper and lower surfaces of eachglass substrate 5 according to the steps illustrated in (A) and (B) ofFIG. 4 . Also, as shown inFIG. 5 , in a further embodiment, each of theglass substrates 5 may be wholly enveloped by the water-soluble film 14. In the described latter two cases, the upper and lower surfaces of theglass substrate 5 for FPD can be protected against damage. Moreover, since the protection of both the upper and lower surfaces of theglass substrate 5 for FPD does not cause any substantial increase in the outer size o f eachglass substrate 5, transferring of theglass substrates 5 at a high efficiency can be surely achieved. Also, the processing of theglass substrates 5 on the production line of the FPD can be simplified with certainty. - Although the present invention has been described in relation to the preferred embodiments thereof, it should be understood that various changes and modifications will occur to a person skilled in the art without departing from the scope and spirit of the invention as claimed in the accompanying claims.
