Description

Glass plate packing equipment

The present invention relates to a packing device for glass plates. In particular, the present invention relates to a glass plate packing device for packing a large glass substrate such as a liquid crystal display or a plasma display and a large glass plate of an intermediate product in the manufacturing process.

In recent years, there is a growing need for larger glass plates used in flat panel displays such as glass substrates for liquid crystal displays and glass substrates for plasma displays. 2. Description of the Related Art Conventionally, as a glass plate packing device for transporting such a glass plate, vertical glass plate packing devices disclosed in Patent Documents 1 and 2 are known.

This packing device for glass plates is described as a pedestal and a bottom rail (described in Patent Document 1 as “surface on which the glass plate of the pedestal is placed”, and described in Patent Document 2 as “bottom support plate”. A mounting surface is formed on the upper surface of the base, and this mounting surface is finished to a predetermined flatness by machining. The bottom beam is set on the mounting surface at a predetermined inclination angle, and the lower edge of the glass plate is mounted on the bottom beam. Similarly, the back plate is erected at a predetermined angle on the mounting surface, and the surface of the glass plate is received by the back plate. In addition, as in Patent Document 2, the glass plate packing device is provided with a press plate that abuts against a side portion of the glass plate received by the back plate and restricts the side movement of the glass plate. Therefore, the glass plate is loaded on the bottom beam with the inclination angle of the back plate, and the lateral displacement is regulated by the press plate, that is, the glass plate is positioned with respect to the glass plate packing device. And packed in a glass plate packing device.

By the way, in the glass plate laminated | stacked on the packaging apparatus for vertical glass plates disclosed by patent document 1, 2, if plate | board thickness becomes thin (for example, plate | board thickness 0.4-1.8mm), vibrations, such as transportation, will be carried out. Therefore, it tends to be easily broken from the lower edge of the glass plate in contact with the bottom rail.

Therefore, a sheet material having a cushion function is stuck on the bottom beam of the glass plate packaging device in order to prevent the end face of the glass plate from cracking. The sheet material disclosed in Patent Document 1 is a polyethylene or elastomer that is a material having a high elastic modulus, a high elastic recovery rate, and a material that is less likely to generate dust due to friction with the lower edge of the glass plate and that has less degassing. Is used. Further, the sheet material disclosed in Patent Document 2 uses a cushion material such as rubber or foamable resin.

JP 2005-132490 A JP 2005-298062 A

However, as in Patent Documents 1 and 2, the sheet material stuck to the bottom rail alone could not significantly reduce the damage to the glass plate.

On the other hand, the bottom rail may be configured as a single plate-like body as in Patent Document 1, but in this case, increasing the flatness of the plate-like body is not preferable from the viewpoint of manufacturing cost, Since the corner edge part of the lower edge of the glass plate to be placed contacts the sheet material, the sheet material in this part is worn and damaged at an early stage, and the damage to the glass plate is greatly reduced due to this problem. I couldn't.

Therefore, in order to solve the above-mentioned problems, the bottom beam, like the bottom beam of Patent Document 2, is made smaller than the width of the glass plate to be placed, and the corner of the lower edge of the glass plate is used. In addition to preventing wear and damage of the sheet material due to contact with the edge portion, a plurality of bottom rails (two “bottom support plates” in Patent Document 2) are arranged at a predetermined interval.

The present invention has been made in view of such circumstances, and is directed to a glass plate packaging device in which the lower edge of a glass plate is placed on a plurality of bottom rails as disclosed in Patent Document 2, as described above. An object of the present invention is to provide a glass plate packaging device that can significantly reduce damage to the glass plate with a simple structure by improving existing components.

The applicant of the present application is that a plurality of bottom rails arranged near the center of the base member are deformed together with the base member due to the weight of the glass plate among the plurality of bottom rails. It has been found that the contact pressure of the glass plate against the glass plate increases, and the stress tends to be concentrated on the glass plate in this portion, whereby the glass plate tends to be damaged.

Therefore, in order to solve such a problem and to achieve the above object, the present invention includes a pedestal having a mounting surface formed on an upper surface, and a tilt at a predetermined angle on the mounting surface of the pedestal. A glass plate provided with a plurality of bottom rails that are provided and supported at the lower edge of the glass plate, and a back plate that is provided on the mounting surface of the pedestal so as to be inclined at a predetermined angle and receive the surface of the glass plate In the packaging apparatus, the plurality of bottom rails are provided on the mounting surface of the pedestal via a base member longer than the width of the pedestal, and with respect to the plurality of bottom rails arranged on both sides of the base member The base member is composed of a bottom beam having at least two types of surface areas so that the surface area of a plurality of bottom beams arranged in the vicinity of the center is increased, and the strength of the base member is reinforced by the weight of the glass plate by the reinforcing member. Been Providing glass plate packaging apparatus according to claim Rukoto.

According to the present invention, by making the surface area of the plurality of bottom rails arranged near the center of the base member larger than the surface area of the plurality of bottom rails arranged on both sides of the base member, Even if it bends, since the surface area of the bottom crosspiece near the center is large, it is possible to maintain contact with a lower surface pressure than in the past. The central portion of the base member is a portion that is directly fixed to the pedestal, and is a portion of the base member where strength is ensured. By increasing the surface area of the bottom beam fixed in the vicinity of the center portion of the base member, where the strength is ensured, the amount of deflection of the bottom beam on both sides is greatly reduced.

Thereby, according to the present invention, since the contact surface pressure of the glass plate with respect to the entire bottom beam is greatly reduced as compared with the conventional one, damage to the glass plate can be greatly reduced. Further, since the strength of the base member of the present invention in the bending direction due to the weight of the glass plate is reinforced by the reinforcing member, the bottom rails on both sides are difficult to bend together with the base member, contributing to the reduction of the contact surface pressure. Yes. Therefore, according to the present invention, the base member is reinforced with a reinforcing member and a simple structure in which the surface area of the plurality of bottom rails arranged in the vicinity of the center portion of the base member is increased, the existing member is improved, and the base member is reinforced. It is possible to greatly reduce damage to the glass plate with a simple structure.

According to the present invention, the pedestal is formed with an opening into which a fork claw of a forklift is inserted, and a plurality of bottom rails having a large surface area disposed near the center are disposed above the opening. It is preferable that

According to the present invention, when the fork claw of the forklift is inserted into the opening of the pedestal and the glass plate packing device is lifted, the glass plate is firmly fixed by the plurality of bottom rails having a large surface area located above the opening of the pedestal. And can be lifted with support. Also, when lifted, both ends of the base member try to bend with the weight of the glass plate, but the base member is reinforced by the reinforcing member, so it is difficult to bend, thereby supporting the glass plate with the all-bottom beam. Since it can be lifted in a state, it is possible to prevent an increase in contact surface pressure during lifting. Furthermore, by making the thickness of the bottom rail thicker than the conventional one, it is possible to suppress the concave deformation of the bottom rail itself, so that the glass plate contacts the entire surface of the bottom rail evenly, so the contact surface pressure is further increased. It can be further reduced and can contribute to preventing damage to the glass plate.

Moreover, according to this invention, the said reinforcement member is a metal cylindrical body fixed along the said base member, and a metal rib member which fixes the both ends of the said base member to the said base. Is preferred.

According to the present invention, the base member can be reinforced with a simple structure by fixing the metal cylindrical body to the base member, and both ends of the base member are fixed to the pedestal by the metal ribs. By doing so, the base member can be reliably reinforced. In addition, the number of metal cylindrical bodies is not limited to one, and may be two or more.

Further, according to the present invention, it is preferable that a sheet-like cushion material having a predetermined thickness and hardness is affixed to the upper surfaces of the plurality of bottom rails.

According to the present invention, in the cushion material affixed to the surface of the bottom rail, the thickness of the cushion material is thicker than that of the conventional one and the hardness is lowered, so that errors in the manufacturing accuracy of each bottom rail surface can be absorbed well. Thereby, since the surface pressure distribution on the bottom rail becomes substantially uniform, the contact surface pressure is further reduced, which can contribute to prevention of damage to the glass plate.
In addition, the present invention provides a glass plate package, wherein a plurality of glass plates are stacked and packed in a vertically placed state with interleaving paper interposed between them in the glass plate packing device described above. .

As described above, according to the glass plate packaging apparatus of the present invention, a simple structure of improving an existing component member that increases the surface area of a plurality of bottom rails arranged near the center of the base member. And the damage of a glass plate can be reduced significantly by the simple structure of reinforcing a base member with a reinforcing member.

FIG. 1 is an overall perspective view of the glass plate packaging device 10 of the embodiment, and FIG. 2 is a left side view of the glass plate packaging device 10 shown in FIG. The glass plate packing device 10 is a packing device for stacking and packing glass plates for liquid crystal displays in a vertically placed state with interleaving paper interposed between them, and packing the glass plates in a slanted state. is there. In addition, the use of the packaging apparatus 10 for glass plates is not limited to this, It can apply as a packaging apparatus of various glass plates.

The glass plate packaging device 10 shown in these figures is a base 14 having a mounting surface 12 formed on the upper surface, and a predetermined angle with respect to the mounting surface 12 of the base 14 via two

base members

16 and 18. Inclined and installed at a predetermined angle with respect to the four

bottom rails

20, 20, 22, 22 on which the lower edge of the glass plate G is placed and the mounting surface 12 of the base 14 Further, the

back plate

24A, 24B, 24C, 24D, 24E is formed, and the angle formed by the bottom bars 20, 22 and the back plates 24A-24E is set to about 90 °. Further, the back plates 24A to 24E are held at the predetermined angle by the frame member 26 erected on the pedestal 14.

The pedestal 14 is configured by welding a plurality of long and short steel materials in the vertical and horizontal directions and in the height direction, and the mounting surface 12 is processed to a predetermined flatness by machining (grinding) after the welding assembly. In addition,

openings

28 and 28 for inserting and removing forklift claws (not shown) are formed on the front surface of the base 14.

The

base members

16 and 18 have the same length and are longer than the width of the pedestal 14, and the central portions of the

base members

16 and 18 are fixed to the mounting surface 12 of the pedestal 14. Both side portions are provided so as to protrude by a predetermined amount from the side surface of the pedestal 14 to the side.

The base member 16 is a steel material having a T-shaped cross section, and two metal prismatic pipes (reinforcing members) 30 and 32 are fixed to the upper surface in the vertical direction. The bottom bars 20, 20, 22, and 22 are fixed to the base member 16 through these

pipes

30 and 32. The

pipes

30 and 32 are disposed along the length direction of the base member 16 and are formed to have a length equal to the length of the base member 16. Therefore, the strength in the bending direction due to the weight of the glass plate is reinforced by the

pipes

30 and 32 on both sides of the base member 16 projecting sideways from the side surface of the base 14.

More specifically, as shown in FIGS. 3 and 4, the lower surface of the pipe 30 disposed in the lower stage is fixed to the upper surface of the base member 16, and the depth direction of the bottom rails 20, 20, 22, 22 is formed on the side surface thereof. The back end is fixed. In addition, the lower surface of the pipe 32 arranged in the upper stage is fixed to the upper surface of the pipe 30, and the lower side surfaces of the back plates 24A to 24E are fixed to the side surfaces at a predetermined interval. As a result, both side portions of the base member 16 projecting sideways from the side surface of the pedestal 14 are reinforced by the two

pipes

30 and 32 in the bending direction due to the weight of the glass plate, and the back plates 24A to 24E are The strength in the direction orthogonal to the surface of the glass plate is reinforced by the two

pipes

30 and 32. The back plate 24A at the center of the five back plates 24A to 24E is fixed at the center in the width direction of the mounting surface 12 of the pedestal 14, and the two back plates on both sides adjacent to the back plate 24A. Lower portions of 24B and 24C are fixed to the bottom rails 22 and 22, and lower portions of two

back plates

24D and 24E on both sides adjacent to the back plates 24B and 24C are fixed to the bottom rails 20 and 20.

On the other hand, the base member 18 is a steel material having an inverted V-shaped cross section. Further, V-shaped grooves 34 are formed in the lower portions of the bottom rails 20 and 22 on the near side in the depth direction, and the top of the base member 18 and the inclined surface thereof are fitted into the grooves 34. The bottom rails 20, 20, 22, and 22 are provided inclined at a predetermined angle.

Further, metal triangular ribs (reinforcing members) 36 and 36 are fixed to the lower surface including both lower ends of the base member 18 projecting from the side surface of the base 14. The rib 36 has a T-shaped cross section, and its end face is fixed to the side surface of the base 14. Therefore, both sides of the base member 18 projecting sideways from the side surface of the base 14 are reinforced by the

ribs

36 and 36 in the strength in the bending direction due to the weight of the glass plate.

The shape of the base member 16 is basically the same as the shape of the rib 36. For this reason, the base member 16 also has a function of the rib 36. In this case, the base member 16 reinforces the strength in the bending direction due to its own weight of the glass plates of the two

pipes

30 and 32.

Next, features of the glass plate packaging device 10 according to the embodiment of the present invention will be described.

As shown in FIGS. 1 and 3, the bottom rails 20, 20, 22, and 22 are provided on the mounting surface 12 of the base 14 via

base members

16 and 18 that are longer than the width of the base 14. The bottom bars 22 and 22 arranged near the center of the

base members

16 and 18 are designed so that the surface area thereof is larger than the bottom bars 20 and 20 arranged on both sides of the

base members

16 and 18. Yes. Specifically, since the depth of each bottom rail is often set to the same size, the surface area is changed by setting the width of each bottom rail to a predetermined dimension. That is, the width of the bottom rails 22 and 22 disposed near the center of the

base members

16 and 18 is increased, and the width of the bottom rails 20 and 20 disposed on both sides of the

base members

16 and 18 is increased. It is performed by making it smaller than the width of. In addition, the

base members

16 and 18 are reinforced by the

pipes

30 and 32 and the

ribs

Thus, by making the surface area of the bottom rails 22 and 22 arranged near the center of the

base members

16 and 18 larger than the surface area of the bottom rails 20 and 20 arranged on both sides of the

base members

16 and 18, Even if the bottom rails 20 and 20 on both sides are bent, the surface of the bottom rails 22 and 22 in the vicinity of the center is large, so that contact at a lower surface pressure than in the prior art can be maintained. The central part of the

base members

16 and 18 is a part that is directly fixed to the pedestal 14, and is a part of the

base members

16 and 18 that has secured strength. By increasing the surface area of the bottom rails 22 and 22 fixed in the vicinity of the central portions of the

base members

16 and 18 in which the strength is secured, the amount of bending of the bottom rails 20 and 20 on both sides is greatly reduced. .
Here, the surface area of each bottom beam means the area of the surface of each bottom beam that becomes the mounting surface side of the vertically placed glass plate, that is, the bottoms arranged on both sides of the base member as shown in FIGS. The area of the crosspiece A (Wa × L) and the area of the bottom crosspiece B arranged near the center of the base member (Wb × L). Here, Wa and Wb indicate the width of the bottom rail, and L indicates the depth of the bottom rail.

As a result, according to the glass plate packaging device 10 of the embodiment of the present invention, the contact surface pressure of the glass plate with respect to the entire bottom rails 20, 20, 22, 22 is greatly reduced as compared with the conventional one. Therefore, damage to the glass plate can be greatly reduced. Further, since the

base members

16 and 18 are reinforced by the

pipes

30 and 32 and the

ribs

36 and 36 in the bending direction due to the weight of the glass plate, the bottom rails 20 and 20 on both sides are joined together with the

base members

16 and 18. It becomes difficult to bend and can contribute to the reduction of the contact surface pressure.

Therefore, according to the packaging apparatus 10 for glass plates of embodiment of this invention, it improves to the existing structural member which enlarges the surface area of the

bottom crosspieces

22 and 22 arrange | positioned in the center part vicinity of the

base members

16 and 18. It is possible to greatly reduce the damage to the glass plate with a simple structure in which the

base members

16 and 18 are reinforced with the

pipes

30 and 32 and the

ribs

36 and 36.

In the embodiment of the present invention, the bottom bars 20 and 22 having two types of surface areas have been described. However, the present invention is not limited to two types, and bottom bars having three or more types of surface areas may be provided. .

Further, according to the glass plate packaging device 10 of the embodiment of the present invention, the base 14 is formed with the

openings

28 and 28 into which the fork claws of the forklift are inserted, and above the

openings

28 and 28. Bottom bars 22 and 22 are arranged. When the fork claw of the forklift is inserted into the

openings

28 and 28 of the pedestal 14 and the glass plate packaging device 10 is lifted, the bottom bars 22 and 22 having a large surface area located above the

openings

28 and 28 of the pedestal 14 It can be lifted with the glass plate firmly supported. Further, when lifted, both ends of the

base members

16 and 18 try to bend by the weight of the glass plate, but the

base members

16 and 18 are bent because they are reinforced by the

pipes

30 and 32 and the

ribs

36 and 36. This makes it difficult to lift the glass plate in a state where it is supported by the all-

bottom bars

20, 20, 22, and 22. Therefore, it is possible to prevent an increase in the contact surface pressure during the lifting.

Furthermore, it is preferable to make the thickness of the bottom rails 20 and 22 of the packaging device for glass plates of the present invention thicker than the conventional one. For example, when the bottom rail is manufactured from a steel plate, the thickness of the bottom rail is preferably 5 to 10 mm in the present invention, compared to the conventional thickness of 2 to 4 mm.

5 shows a conventional bottom rail 1 and FIG. 6 shows a bottom rail 22 near the center of the

base members

16 and 18 according to the embodiment of the present invention. The thickness of the conventional bottom rail 1 is 3 mm, but the thickness of the bottom rail 22 of the embodiment is increased to 8 mm. Thereby, the concave deformation of the bottom rail 22 itself can be suppressed. Moreover, the width dimension of the conventional bottom rail 1 is 100 mm, for example, and the width dimension of the bottom rail 22 is as wide as 200 mm (effective width: 170 mm). Thereby, since the glass plate contacts the entire surface of the bottom rail 22 evenly, the contact surface pressure is further reduced, and it is possible to contribute to prevention of damage to the glass plate. The thickness of the bottom rail 20 is also 8 mm, and the width dimension is 160 mm (effective width: 130 mm).

Further, regarding the reinforcing member composed of the

pipes

30 and 32 and the

ribs

36 and 36, the

base members

16 and 18 can be reinforced with a simple structure by fixing the

pipes

30 and 32 to the

base members

16 and 18. Moreover, the

base members

16 and 18 can be reliably reinforced by fixing the both ends of the

base members

16 and 18 to the base 14 with ribs. The number of the

pipes

30 and 32 is not limited to two, and may be one or three or more depending on the weight of the glass plate.

Furthermore, as shown in FIG. 1 to FIG. 4, it is preferable to affix cushion materials 38 to the surfaces of the bottom rails 20, 20, 22, 22 respectively. The cushion material 38 is thicker than the conventional one, and the hardness is lowered. For example, a conventional cushion material having a thickness of 5 mm and a Shore A hardness (Shore A hardness) of 70 is assumed to be 8 to 15 mm and a Shore A hardness of 40 to 50 in the cushion material 38 of the embodiment of the present invention. Thereby, the error of the manufacturing precision of each

bottom rail

20, 20, 22, 22 can be absorbed favorably. Therefore, since the surface pressure distribution on the bottom rails 20, 20, 22, and 22 becomes substantially uniform, the contact surface pressure can be further reduced, and the glass plate can be prevented from being damaged. For example, as the cushion material, chloroprene rubber, other synthetic rubber, natural rubber, or the like can be used.

Further, cushion materials 40 are also attached to the surfaces of the back plates 24A to 24E that receive the surface of the glass plate.
