2. Description of the Related Art For example, a liquid crystal display (LCD),
A glass plate used for manufacturing a glass panel for various image display devices such as a plasma display (PDP), an electroluminescence display (ELD), and a field emission display (FED), and various electronic display functional elements and thin films for forming The glass plates used as the base material are usually transported as a package from a glass maker or the like to a display maker or the like in a state where a plurality of glass plates are stored and held as a set.

Despite the fact that this type of glass plate is thin and easily broken, it must be transported properly and inexpensively while maintaining high quality. Therefore, the packaging material used for storing and holding the glass plate is easy to manufacture. Various characteristics such as high cleanliness, anti-seismic retention, damage resistance, high storability, high transportability, and easy access are required.

In order to meet such a request, for example, according to Japanese Patent No. 2916836, as shown in FIG.
Disclosed is a packing material 50 for glass substrates, which has a substantially L-shaped cross section and has a plurality of substrate holding grooves 51 on the inner wall and a band mounting groove 53 for mounting the binding band 52 on the outer wall. . Then, a packaging body 60 manufactured using this packaging material 50.
Is a cube in which a plurality of glass substrates G are arranged in parallel at predetermined intervals to form a cube.
It is formed by inserting it into the substrate holding groove 51 of 50 and fitting and fixing the square portion of the cube with each packing material 50.

The packing material having such a structure is lower in material cost and manufacturing cost than conventional so-called box-type packing materials, that glass substrates of various sizes can be packed in the same, There are advantages such that the volume in the state can be reduced, cleaning and drying can be easily performed even if it is contaminated by repeated use through a container, and huge cleaning equipment is not required. In addition to these, vibration of the glass substrate during transportation can be suppressed, storage and transportation efficiency in the state where the glass substrate is stored is high, and contact with the adjacent glass substrate during storage and removal of the glass substrate is also possible. There is also the advantage that there is no risk of interference and that the operation of putting in and out can be done easily.

[0006]

By the way, in the production of the above-mentioned various image display devices and the like, a method has been adopted in which a plurality of glass panels are made from one sheet of raw glass, and with this, The current situation is that large glass is being promoted in the raw glass formed and processed by glass makers. More specifically, for example, a glass panel of a liquid crystal display has a diagonal size of about 10 to 20 inches, but for the purpose of reducing the manufacturing cost and improving the production efficiency (throughput), a large-sized glass panel is used. Since the multi-method in which a large number of glass panels are made in the raw glass has been adopted, it is attempted to make the raw glass manufactured by a glass manufacturer as large as possible. Specifically, in the initial stage of commercialized mass production, the size of the raw sheet glass was about 300 × 400 mm, but thereafter, as the number of glass panels taken increased, 370
× 470 mm size, 550 × 650 mm size, 68
Larger plates are being made to a size of 0 × 680 mm, etc., and at present, a glass sheet having a size of about 1000 × 1200 mm has been manufactured.

However, due to the large size of the raw glass plate, it becomes difficult to handle it.
It becomes necessary to pay more attention to packing and transportation, and if the conventional packing method using packing materials is used, the following problems will occur.

That is, the conventional packing material 50 illustrated in FIG.
Since the squareness of the bent portion of the substantially L shape changes during repeated use and it is easy to open to the outside, it causes a groove shift especially when packing large glass plates and is broken by the glass substrates coming into contact with each other. There is a risk. Further, since the exposed portion of the glass substrate arranged on the outermost portion becomes large, there is a risk of breaking even if a slight mechanical shock is applied from the outside.

Further, in the past, when the worker or the like moves or conveys the package in order to change the place where the package is placed, the worker or the like holds and lowers the lower end of the package, Alternatively, a method of grasping the binding band and lifting it has been adopted. These methods do not cause much trouble when the glass plate is a small plate, but as described above, when the glass plate becomes a large plate, the weight increases significantly and the balance is stable. Since it becomes difficult to lift the package in this state, there is a problem that the ease of work is hindered and the package cannot be moved smoothly.

The present invention has been made in view of the above circumstances, and has a small shape change over a long period of time, and even when a large plate-like body is packed, it is exposed to the outermost portion by a mechanical shock from the outside. The plate-shaped body located is less likely to break, the plate-shaped body to be stored is less likely to be contaminated, and the plate-shaped body can be fixed so as not to vibrate during transportation. To provide a packaging material and a packaging body that are easy to put in and take out without fear of contact or interference with an adjacent plate body when the plate body is stored or taken out, and by having a large plate body. It is an object of the present invention to provide a packaging body and a method of transporting the packaging body that can smoothly move the position while improving the workability or the work efficiency even under the condition that the weight of the packaging body and the handling property are deteriorated. Subject.

DISCLOSURE OF THE INVENTION The present invention, which has been made to achieve the above-mentioned technical objects, is a packing material for accommodating and holding a plurality of plate-like bodies arranged in parallel in a substantially upright manner and having a cross section. Has a substantially L shape, and has a base portion in which a plurality of holding grooves for inserting the corners of each plate-like body are formed on the inner wall, and side wall portions formed on both sides of the base portion. Be attached.

According to this structure, since the side wall portions are formed on both sides of the base portion having a substantially L-shaped cross section, even if the packing material is repeatedly used for a long period of time, the side wall portion is present. As a result, the perpendicularity (approximately 90 degrees) of the substantially L-shape is properly maintained, and the angle becomes difficult to open. Therefore, even when a large plate-shaped body is packed, the plate-shaped body does not shift from the holding groove of the packing material, and it is possible to prevent cracks due to contact between the plate-shaped bodies. . The number and shape of the holding grooves formed in the packing material may be appropriately set according to the size and thickness of the plate-shaped body to be packed. For example, the number of grooves is about 10 to 100 and the groove shape is deep. 2 to 20
It may be formed in a V-shape, a U-shape, a U-shape, etc. of about mm.

This packing material can pack plate-like bodies of various sizes, can reduce the volume in an empty box, and can be washed and dried even if it is contaminated by repeated use by passing through the box. Is easy and does not require huge cleaning equipment. In addition, since the plate-shaped body does not vibrate during transportation by binding each packing material with a band, etc., storage and transportation efficiency in the plate-shaped body stored state is high, and the plate-shaped body is stored and taken out. Since there is no risk of contact or interference with the adjacent plate-like body, the operation for taking in and out is easy.

In this case, the side wall may have a rectangular shape or another polygonal shape, but the side wall has a substantially right-angled triangle having a hypotenuse connecting the tip in the height direction and the tip in the depth direction of the base portion. It preferably has a shape. With this structure, it is possible to most effectively increase the rigidity of the base portion without using wasteful material, maintain an appropriate squareness for long-term repeated use without causing an unreasonable increase in manufacturing cost. Can be achieved.

Further, according to the present invention made in order to achieve the above-mentioned technical problem, the square portions of a plurality of plate-like members arranged in parallel in a substantially upright state have a cross section in which each of the four packing materials is substantially formed. In a packing body that is inserted into a plurality of holding grooves formed in the inner wall of each L-shaped base portion and each plate body is integrally stored and held by four packing materials, It is characterized in that side wall portions are formed on both sides of the base portion of the lower packing material holding the lower corner portion and / or on both sides of the base portion of the upper packing material holding the upper corner portion.

According to this structure, since the perpendicularity of the base portion of at least one of the lower packing material and the upper packing material is appropriately maintained for a long time due to the presence of the side wall portion, In addition to being able to enjoy the same advantages as in the above case, since the exposed portion of the plate-shaped body located at the outermost part can be reduced by the side wall portion thereof, the plate-shaped body is cracked due to a mechanical shock from the outside. The risk is reduced. The side wall portion is preferably formed for both the lower packing material and the upper packing material, but, for example, when the height dimensions of the lower packing material and the upper packing material are different, It is also possible to take measures such as forming the side wall only for the packing material on the long side.

Also in this case, if the side wall has a substantially right-angled triangular shape having a hypotenuse connecting the tip in the height direction and the tip in the depth direction of the base body, wasteful material is formed. The plate-like body is satisfactorily accommodated and held by the packing material in which the rigidity of the base portion is most effectively increased without using it, and the exposed portion of the plate-like body located at the outermost part is appropriately reduced.

Further, the height dimension of the lower packaging material is longer than the height dimension of the upper packaging material, and the side wall portions are formed on both sides of the base portion of the lower packaging material. Is preferred. Further, under such a condition, the vertical dimension of the lower packaging material is 1/2 or more of the vertical dimension of the plate-shaped body,
Alternatively, it is preferably set to 2/3 or more, more preferably 3/4 or more. With this configuration, even when the binding band is removed or the upper packing material is removed, the lower corner portion of the plate body is stably held by the lower packing material, so that the plate body can be retained. Even when using an automatic take-out device, it can be taken out safely.

Moreover, the substantially rectangular parallelepiped box body is constructed by aligning the oblique side portions of the side walls of the pair of the lower packing materials with each other, and the pair of lower side packing materials are provided in the inner space of the box body. It is preferable that the upper packing material can be housed. According to this structure, not only the volume of the pair of lower packing materials in the empty state can be made as small as possible, but also the pair of upper packing materials can be accommodated in the internal space thereof, and therefore, the transportation in the empty state can be performed. It facilitates and narrows the transportation space, ensuring excellent handling.

In this case, the side wall portion is formed on both the base portion of the lower packing material and the base portion of the upper packing material, and a step is formed on the oblique side portion of at least one of the side wall portions. It is preferable. That is, when the hypotenuses of the pair of lower packing materials and / or the hypotenuses of the pair of upper packing materials are matched with each other, by engaging the respective steps, the packing materials slide along the hypotenuses. Therefore, it is possible to further facilitate the transportation in the empty box state and further improve the handling property.

On the other hand, in order to smoothly carry or move the position of the package in which the plate-like body is stored and held,
It is preferable to form a concave portion or a convex portion for carrying on the outer wall of the lower packaging material and / or the outer wall of the upper packaging material. According to this structure, even if the weight is large due to the large plate-shaped body, the operator or the like can remove the concave portion or the convex portion of the lower packaging material or the concave portion or the convex portion of the upper packaging material. Since the position of the package can be easily moved by grasping and lifting, it is not necessary to adopt the conventional method of lifting the package by grasping the lower end of the upper packaging material or the lower packaging material or the binding band. , Work efficiency is greatly improved.

Further, a construction is adopted in which a carrying belt is wound around the outer wall of the lower packing material and the outer wall of the upper packing material, and a carrying hook member is fixed to the carrying belt. You can also Even with such a configuration, the worker or the like can easily move the position of the package by gripping and lifting the hooking member fixed to the conveyor belt, and the work efficiency is greatly improved in the same manner as above. To be improved.

Furthermore, the present invention made to achieve the above-mentioned technical object is a carrying method for carrying the above-mentioned package, wherein a carrying sheet is provided between the lower packing material and the placing surface. It is characterized in that it is interposed and the transport sheet is slid on the mounting surface. In this case, the carrying sheet has a large frictional resistance at the contact surface with the lower packing material so that relative sliding with the packaging body does not occur, and the relative sliding surface with the mounting surface easily occurs. The frictional resistance of the contact surface with is small,
Properties such as excellent durability against repeated use, resistance to water and chemicals, hygiene, lightweight, economical are required. Therefore, a resin sheet that meets these requirements is suitable. Specifically, for example, a resin sheet such as Nisseki Sheet Pallet (Nisseki Sheet Pallet System Co., Ltd./Nippon Petrochemical Co., Ltd.)
Can be used.

According to this structure, the packing body is placed on the carrying sheet laid on the placing surface such as the floor, so that the carrying is carried between the lower packing material and the placing surface. With the sheet for use interposed, and under such a state, by pulling the sheet for transportation and sliding it on the mounting surface, the package moves together with the sheet for transportation. This allows the package to be moved easily without scratching the lower packaging of the packaging and the mounting surface, improving the work efficiency while ensuring the durability of the lower packaging. Becomes

In the above invention, the packing material can be made from various resin foams, but if it is made from foamed polyethylene or polypropylene having a foaming ratio of 5 to 20 times, it is cheap and easy by injection molding. It is preferable in that it can be molded into, it is difficult to deform, it has a large buffering effect, and it has a small amount of dust and a small dusting property.

Thereby, even when a large plate-shaped body is packed, the plate-shaped body does not shift from the holding groove of the packing material, and it is possible to prevent cracks due to contact between the plate-shaped bodies. .

In this case, if the shape of the side wall portion is a substantially right triangle having a hypotenuse connecting the tip in the height direction and the tip in the depth direction of the base portion, it may be rectangular or other polygonal shape. Compared with the case, the rigidity of the base part can be most effectively increased without using waste materials, and the bending angle is appropriate for long-term repeated use without causing an unreasonable increase in manufacturing cost. Is maintained.

Further, according to the packaging body of the present invention, since the side wall portions are formed on both sides of the base portion of the lower packaging material and / or the upper packaging material, the angle of the bent portion of the base portion is the side wall portion. Is maintained properly over the long term due to the presence of
In addition to enjoying the same advantages as in the case described above, the side wall portion can reduce the exposed portion of the plate-shaped body located at the outermost portion, so that the plate-shaped body is cracked due to a mechanical shock from the outside, etc. The risk of is reduced.

Also in this case, if the side wall is formed into a substantially right-angled triangular shape having a hypotenuse connecting the front end in the height direction and the front end in the depth direction, useless material is used. The most effective packing material that has increased rigidity of the base is that the plate is stored and held well, and the exposed part of the plate located at the outermost part is appropriately reduced, and the plate breaks. The rate of occurrence of etc. decreases efficiently.

Further, the height dimension of the lower packing material is made longer than the height dimension of the upper packing material, and the side wall portions are formed on both sides of the base portion of the lower packing material. By setting the vertical dimension of the lower packaging material with the side wall formed to be 1/2 or more of the vertical dimension of the plate-like body, even when the binding band is removed or the upper packaging material is removed. Since the lower corners of the plate-like body can be stably held by the lower packing material, the plate-like body can be taken out properly and safely even when an automatic take-out device for automatically taking out the plate-like body is used.

Moreover, a substantially rectangular parallelepiped box body is constructed by mutually matching the hypotenuses of the side walls of the pair of lower packing materials, and the pair of upper sides is provided in the inner space of the box body. If configured so that the packing material can be stored,
Not only can the volume of the pair of lower packing materials in the empty state be made as small as possible, but also the pair of upper packing materials can be stored in the internal space, facilitating the transportation in the empty state and narrowing the transportation space. Can be achieved, and excellent handleability can be secured.

Further, if a side wall portion is formed on both the base portion of the lower packing material and the base portion of the upper packing material, and a step is formed on the hypotenuse portion of at least one of the side wall portions, a pair of lower parts is formed. When the hypotenuses of the side packing materials and / or the hypotenuses of the pair of upper packing materials are matched, the respective packing materials will not slip along the hypotenuses due to the engagement of the steps, and in the empty state. Further facilitates the transportation and further improves the handleability.

On the other hand, by forming a concave portion or a convex portion for carrying on the outer wall of the lower packing material and / or the outer wall of the upper packing material, even if the weight is large due to the large plate-like body. , A worker or the like can easily move the position of the package by grasping and lifting the concave or convex portion of the lower packaging material or the concave or convex portion of the upper packaging material. Efficiency is greatly improved.

Further, there is a case where the carrying belt is wound around the outer wall of the lower packing material and the outer wall of the upper packing material, and the carrying hooking member is fixed to the carrying belt. However, the worker or the like can easily move the position of the package by gripping and lifting the hooking member fixed to the conveyor belt, and the work efficiency is greatly improved in the same manner as described above.

Further, according to the method of transporting a package according to the present invention, a transport sheet is interposed between the loading surface and the lower packing material, and the transport sheet is slid on the loading surface. Therefore, the package can be easily transported without scratches or the like on the lower packaging material and the mounting surface, and the work efficiency can be improved while ensuring the durability of the lower packaging material.
