Description

  The present invention relates to a glass plate package, and in particular, prevents the occurrence of damage and surface scratches when transporting a thin glass plate used for a liquid crystal display or the like, and packs and stores a large glass plate with high storage efficiency. The present invention relates to a glass plate package that can be used.

  Conventionally, it is used as a substrate for forming glass plates used in the production of glass panels for flat panel displays such as liquid crystal displays, plasma displays, electroluminescence displays, field emission displays, and various electronic functional elements and thin films. A glass plate or the like is usually conveyed as a package from a glass maker to a display maker or the like in a state where a plurality of sheets are stored and held as a group.

  In addition, for example, in manufacturing the above-described various flat display glass panels, a technique in which a plurality of glass panels are produced from a single glass sheet has been adopted, and the glass manufacturers are molded and processed accordingly. The current situation is that large glass is being promoted. More specifically, for example, when manufacturing a glass panel of a liquid crystal display, a multi-system in which a large number of glass panels are formed in a large plate glass is employed for the purpose of reducing manufacturing cost and improving production efficiency (throughput). As a result, attempts have been made to make the glass plate manufactured by glass manufacturers as large as possible, and practical application has been attempted.

  Specifically, in the initial stage of practical mass production, the size of the base glass was about 300 × 400 mm, but after that, with the increase in the number of glass panels taken, the size of 370 × 470 mm, 550 × 650 mm The size of the glass plate is increasing to 680 × 880 mm size, 1000 × 1200 mm size, 1500 × 1800 mm size, etc., and now 1950 × 2250 mm size (thickness 0.7 mm or less) base glass is being manufactured. .

  In this case, the above-mentioned exemplified glass plates and glass plates according to them are actually thin and easily breakable with such a large plate.

Regarding packaging of this type of glass plate, as described in Patent Documents 1 and 2 below, a plurality of glass plates are vertically or substantially spaced at regular intervals by using a protective pad for buffering or a separating member. There is known a packaging technique in which a vertical posture is arranged in parallel.

  However, as disclosed in Patent Documents 1 and 2 above, when a plurality of glass plates are stored in a state in which the flat posture of the glass plates is maintained, glass is subject to severe vibration during transportation. The plate could move and break. In addition, when foreign matter such as dust or dirt is sandwiched between the glass plate and the protective sheet, the glass plate moves relative to the protective sheet material due to vibration during transportation, and is moved to the surface of the glass plate. Problems such as scratches may occur.

  Further, in recent years when the size of the glass sheet has been increased, it is disadvantageous in terms of cost that a large glass sheet is stood or stacked and stored in a state of maintaining a flat posture because transportation efficiency at the time of transportation decreases. In addition, when the future increase in the size of glass plates (for example, 2300 × 2600 size or larger) proceeds, a large glass plate package is loaded on a truck bed as a means of transportation. There is also a possibility that the width dimension of the glass plate package may not fit within the truck bed width.

  The present invention has been made in view of the above circumstances, and even when subjected to severe vibration during transportation, the movement of the glass plate is difficult to occur, and it is possible to prevent the occurrence of breakage and surface damage due to this, and the glass. It is a technical problem to appropriately cope with the increase in the size of the package accompanying the increase in the size of the plate and the difficulty in handling due to this.

The present invention made in order to solve the above technical problem includes a mounting surface for mounting a glass plate in a substantially vertical direction, and a backrest surface extending in a substantially vertical direction from a rear end portion of the mounting surface. On a base plate having a substantially L-shaped cross section, a plurality of glass plates are provided with a protective member between each other, and stored in a leaning state on the backrest surface. The backrest surface of the base is curved, a plurality of glass plates are housed in a curved state along the backrest surface, and a pressing member having a curved surface complementary to the backrest surface is attached to the last glass plate. It is characterized by being arranged in a leaning state .

According to the present invention, since the backrest surface of the base is curved and the glass plate stored in a standing state is curved and packaged along the backrest surface, the glass plate has a posture with resistance to impact. The glass plate is difficult to move even when a strong impact is applied to the package, and damage and surface damage due to movement of the glass plate can be prevented. Moreover, since the linear dimension of the glass plate in a bending direction is shortened because the glass plate is curved, it is possible to improve packing efficiency and transport efficiency. Therefore, for example, even when a glass plate having a width exceeding the loading limit width of the transport truck is transported, the width of the entire package can be shortened by curving the glass plate. Loading and transportation are possible. Further, by arranging the pressing member having a curved surface complementary to the backrest surface in a leaning state on the rearmost glass plate, the glass plate can be stored more reliably and stably.

  In addition, the degree of bending of the glass plate described above is that, in the case of a glass plate having a thickness of 0.7 mm or less, the maximum amount of bending of the glass plate caused by the bending is 1/3 or less of the width dimension in the bending direction of the glass plate. preferable. If the maximum amount of deflection of the glass plate exceeds 1/3 of the width dimension, the tensile stress generated on the surface of the glass plate becomes too large. As a result, invisible micro-scratches are caused on the surface of the glass plate by slight rubbing during packaging. The tendency to cause breakage of the glass plate starting from the minute scratch is increased.

  Further, in the present invention, the protective member is preferably one that contacts the entire surface or substantially the entire surface of a glass plate such as a resin film, a resin sheet, or paper such as a slip sheet, or the protection of these sheet-like materials. It is preferable to use the member in combination with a spacer that contacts only the surface edge of the glass plate.

  When the glass plate to be packed is a glass substrate used as a final product, the protective member is more preferably a foamed resin sheet that contacts the entire surface or substantially the entire surface of the glass plate.

  When a foamed resin sheet is used as the protective member, a good cushioning property is obtained as compared with paper or a resin film, and the impact acting on each glass plate during transportation is further alleviated. Further, since the surface of the foamed resin sheet has higher adhesion (or frictional resistance or contact resistance) to the surface of the glass plate than papers such as slip sheets, the glass plate is less likely to slip with respect to the foamed resin sheet. Thus, the probability of relative movement between the two becomes extremely high. Therefore, even if foreign matter such as dust or dirt is present between the glass plate and the foamed resin sheet, the probability that the foreign matter will rub against the surface of the glass plate is reduced, and the foreign matter causes the glass plate. It is more difficult to cause defects such as scratches on the surface.

  Moreover, it is preferable that the thickness of a foamed resin sheet is 0.3-5.0 mm. In this way, when a plurality of glass plates are interposed between each other and a foamed resin sheet is interposed between the glass plates and the glass plates are bent and stored in a leaning state, the glass plates are sufficiently protected and the like. It can be avoided that the glass plate is unduly bulky in the thickness direction of the glass plate. That is, if the thickness of the foamed resin sheet is less than 0.3 mm, the cushioning function and the buffering function that the foamed resin sheet originally has cannot be sufficiently exhibited, and the protection of the glass plate is hindered. As a result, the foamed resin sheet is too thin, and it is easy to be torn and difficult to handle during the storing operation. On the other hand, if the thickness of the foamed resin sheet exceeds 5.0 mm, even if the number of glass plates to be stored is not so large, the thickness becomes unreasonably bulky in the thickness direction, and there is waste in terms of cost. Arise. Therefore, if the thickness of the foamed resin sheet is within the above numerical range, such a problem does not occur. In this case, the more preferable thickness of the foamed resin sheet is 0.5 to 2.0 mm.

  Moreover, in said structure, it is preferable that the expansion ratio of the said foamed resin sheet is 10 to 40 times.

  If it does in this way, the situation where tearing arises can be avoided after securing the suitable cushioning property etc. with respect to the glass plate of a foamed resin sheet. That is, when the foaming ratio of the foamed resin sheet is less than 10, the foamed resin sheet becomes too hard, so that the required cushioning property cannot be obtained and the glass plate cannot be sufficiently protected. On the other hand, when the expansion ratio of the foamed resin sheet exceeds 40, the foamed resin sheet becomes too soft, and the tear tends to occur and the handling during the storing operation becomes difficult. Therefore, if the expansion ratio of the foamed resin sheet is within the above numerical range, such a problem does not occur. In this case, the more preferable expansion ratio of the foamed resin sheet is 20 to 30 times.

  In addition, the foamed resin sheet preferably does not contain an antistatic agent in order to prevent adhesion of dirt when coming into contact with the surface of the glass plate. However, a high molecular weight type resin is used without using a surfactant, even if the material itself contains a foamed resin sheet containing an antistatic agent (for example, a polymer type antistatic agent) or a surfactant. Since the foamed resin sheet using the surfactant hardly causes a problem of adhesion of dirt when it comes into contact with the surface of the glass plate, these foamed resin sheets can be used as a protective sheet material. In addition, since the foamed resin sheet using the low molecular weight type surfactant has a large amount of dirt when it comes into contact with the surface of the glass plate, it should be avoided to use this foamed resin sheet as a protective sheet material. Be wise.

  On the other hand, when the glass plate to be packed is a mother glass, that is, a glass original plate that is continuously drawn from molten glass and is roughly cut, the protective member covers the entire surface or substantially the entire surface of the glass plate. More preferably, it is composed of an interleaving paper and a spacer that contacts only the surface edge of the glass plate.

  That is, the glass plate as the glass original plate is finished into a glass substrate having a predetermined size by being cut at the transport destination. Also, in this fine cutting process, the glass plate is usually taken out from the package together with the protective member, and after the protective member is placed on the lower surface, the glass plate is cut by the scriber coming into contact with the upper surface of the glass plate. Is done. Therefore, in view of the fact that it is necessary not to bend the glass plate at the time of fine cutting by the scriber without reducing the handling workability in the processing line at the transport destination, a slip sheet is used as the protective member. More preferred. However, if only the slip sheet is interposed in each glass plate and crimped at the time of packing, the foreign matter (impurities) contained in the slip sheet is transferred to the glass plate, and the foreign matter is crimped to the glass. There is a danger that it will stick to the plate and make it difficult or impossible to remove it. Therefore, by interposing a spacer that contacts only the surface edge of the glass plate together with the slip sheet, the problem of adhesion and sticking of foreign matter due to the slip sheet is avoided, and only the spacer is removed at the transport destination. The slip sheet can be transferred to the processing line together with the glass plate, and the fine cutting operation can be performed well. Therefore, by using a combination of a slip sheet and a spacer as a protective member, not only the dust-proofing effect on the effective surface of the glass plate but also the fine cutting operation of the glass plate can be performed satisfactorily.

  In the above configuration, the interleaving paper is preferably made of paper having good hygroscopicity, which is free from curling and misalignment during packing and unpacking, transfer of paper skin pattern, burn phenomenon, and dust.

  The spacer may be selected from materials that are not easily deformed and have a large buffering effect. For example, the spacer is manufactured by injection molding a hard resin such as polypropylene resin or polyethylene resin, and is manufactured by plastic cardboard or cardboard. Can be used, but if cardboard (compressed paper or cardboard) containing cellulose fiber as a component is used, it has sufficient strength so that it does not easily deform and has a lower hardness than a glass plate. You can enjoy such advantages. Specifically, it is preferable to use a transformer board (trade name, manufactured by Oji Paper Co., Ltd.). The shape of the spacer may be a frame shape that contacts the entire circumference of the surface edge of the glass plate or a U-shape or a linear shape that contacts a part of the surface edge.

  Moreover, in this invention, it becomes easy to convey a package body with a forklift etc. by mounting a base on a pallet for conveyance.

  In the present invention, the impact applied to the glass plate accommodated in the upper part is further reduced by disposing an impact absorber on the mounting surface of the base or on the transport pallet. Thus, vibrations to the glass plate can be more effectively suppressed.

  Any of the above shock absorbers can be used as long as they have the effect of sufficiently mitigating the impact and preventing them from being transmitted to the glass plate even when subjected to large vibrations when transporting the package of the glass plate. However, in consideration of functionality, workability, etc., it is preferable to use a soft elastomer having a high stress dispersibility. Specifically, it is preferable that it is made of a soft elastomer having a hardness (JIS K6301, spring hardness Hs) of less than 30, preferably less than 10, more preferably less than 5. Examples of such soft elastomers include urethane gel (trade name) manufactured by Hamamatsu Platec Co., Ltd., urethane elastomer manufactured by Sanshin Kosan Co., Ltd .: sorbosein (trade name), silicone gel manufactured by Geltech Co., Ltd .: α gel (trade name) ) Etc. can be used.

  The impact absorber is preferably in the form of a sheet. If the thickness is within the range of 0.3 to 30 mm, the effect of absorbing the impact on the glass plate is easily exhibited, and the upper and lower sides are inappropriate. It becomes possible to avoid becoming bulky. The shock absorber is preferably arranged so as to cover all of the support surface of the base on the lower surface or the mounting surface of the transport pallet, but it can withstand the load of the glass plate and has a non-uniform load during transport. As long as is not added, it may be arranged so as to cover only a part of the surface. The shock absorber may be attached simply by placing it, but may be attached mechanically or adhered. Further, after the shock absorber is disposed on the support surface of the base, a bottom plate may be placed thereon, and a glass plate may be placed on the bottom plate.

  Further, in the present invention, the glass plate on the base is surrounded by a four-side wall cylinder covering the entire or substantially the entire four side portions of the stored glass plate, and further, the upper end opening of the four-side wall cylinder is covered. By covering with, the glass plate on the base is covered with a box, so that each glass plate stored in the inside is cut off from the external space and exists in the external space The probability that foreign substances such as dust and dirt adhere to the glass plate will be greatly reduced, and the influence on the glass plate caused by changes in external temperature or humidity can be mitigated, thus protecting the glass plate more effectively. it can. Any of the four side wall cylinders and the lid can be used as long as it is a material that does not deform even when used for a long period of time, and is preferably made of metal or hard resin.

  Moreover, in said structure, a glass plate can be more stably accommodated in the four side wall cylinder which comprises an outer enclosure by interposing a buffer material in the gap | interval of a glass plate and a four side wall cylinder. The cushioning material is made of a material having a cushioning effect such as urethane resin, polypropylene resin, polybutylene resin, urethane rubber, silicone rubber, etc., and its shape is a sheet shape that completely or almost completely surrounds the four side walls of the stored glass plate. However, it may be in the form of a block that is partially interposed.

  As described above, according to the packaging body of the glass plate according to the present invention, the backrest surface of the base is curved, and the glass plates stacked in a leaning state are curved and packaged along the backrest surface. The glass plate can be stored in a posture with resistance to impact, and even when a strong impact is applied to the package, the glass plate is difficult to move, and damage and surface damage due to movement of the glass plate can be prevented. Further, since the glass plate is curved, the linear dimension of the glass plate in the bending direction is shortened, so that the packing efficiency and the transport efficiency can be improved. Therefore, for example, even when a glass plate having a width exceeding the loading limit width of the transport truck is transported, the width of the entire package can be shortened by curving the glass plate. The board can be loaded and transported on a truck.

  Further, in the present invention, if the holding member having a curved surface complementary to the backrest surface is disposed in a leaning state on the rearmost glass plate, the curved posture of the glass plate can be reliably maintained, and more Glass plates can be stacked and stored in a stable state.

  Moreover, in this invention, when the glass plate to be packed is a glass substrate (glass panel) which is a final product, by using a foamed resin sheet as a protective member, good cushioning and adhesion to the surface of the glass plate (Or frictional resistance or contact resistance) is obtained, and the impact acting on each glass plate during transportation is further mitigated, and foreign matter such as dust and dust is temporarily placed between the glass plate and the foamed resin sheet. Even if it is interposed, the probability that the foreign material rubs against the surface of the glass plate is reduced, and it is more difficult to cause problems such as scratching the surface of the glass plate due to the foreign material.

  In the present invention, when the glass plate to be packed is a glass original plate as mother glass, a dustproof effect on the effective surface of the glass original plate can be obtained by using a combination of a slip sheet and a spacer as a protective member. In addition, it can be used for a fine cutting operation of the glass original plate.

  Moreover, in this invention, it becomes easy to convey a package body with a forklift etc. by mounting a base on the pallet for conveyance.

  Further, in the present invention, by providing an impact absorber on the mounting surface of the base or on the transport pallet, the impact applied to the glass plate stored in the upper part is further alleviated. In addition, vibration to the glass plate can be more effectively suppressed. As this shock absorber, in particular, by using a soft elastomer excellent in functionality, workability, etc. in the form of a sheet, the effect of absorbing the impact on the glass plate is easily exhibited, and it becomes unduly bulky. It can be avoided.

  Further, in the present invention, the glass plate on the base is surrounded by a four side wall cylinder covering the entire surface or almost the entire surface of the four side portions of the laminated glass plates, and the upper end opening of the four side wall cylinder is covered with a lid. By using the covering structure, the probability that foreign matters such as dust and dust existing in the external space will adhere to the glass plate and contaminate it is greatly reduced, and the glass plate is caused by changes in the external temperature or humidity. Can be mitigated and the glass plate can be protected more effectively.

  Moreover, in said structure, a glass plate can be more stably accommodated in the four side wall cylinder which comprises an outer enclosure by interposing a buffer material in the gap | interval of a glass plate and a four side wall cylinder.

  Furthermore, it is good also as a structure which covers the circumference | surroundings with a stretch film, a shrink film, etc. in the state by which the glass plate was laminated | stacked and accommodated on the base.
