SUMMERY OF THE UTILITY MODEL
Problem to be solved by utility model
However, if the cushion material is fixed by the adhesive, the adhesive may peel off or volatilize, and a contamination source derived from the adhesive may adhere to the glass plate. In particular, when a contamination source derived from the adhesive enters between the laminated glass plates, the contamination source is likely to be strongly adhered to the surfaces of the glass plates by the weight of the glass plates. Therefore, such a contamination source derived from the adhesive is often difficult to remove from the glass plate by washing, and there is a problem that the contamination source may become a defect of the glass plate.
In addition, when the same cushioning material is reused in a plurality of deliveries, the cushioning performance of the cushioning material inevitably decreases. Therefore, the cushion material needs to be replaced at a certain frequency, but if the cushion material is fixed by an adhesive, the cushion material cannot be easily separated from, for example, a metal plate material to which the cushion material is fixed. As a result, it is substantially impossible to replace only the cushioning material, and there is a problem that the maintainability is extremely poor.
The utility model provides a pallet for packing glass plates and a glass plate package body, which prevent the pollution of the glass plates and have good maintainability.
Means for solving the problems
The inventors of the present application have conducted intensive studies and, as a result, found that: the present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a glass sheet laminate that can suppress the positional displacement of a cushioning material by the weight of the glass sheet laminate, even when the cushioning material fixed with an adhesive in the past is simply detachably mounted without using an adhesive.
The pallet for packing glass sheets according to the present invention comprises: a base portion that accommodates a glass sheet laminate in which a plurality of glass sheets are laminated with a protective sheet interposed therebetween in a vertical posture, above; a bottom edge support portion that supports a bottom edge of the glass sheet laminate; and a back support portion that supports a back surface of the glass sheet laminate, wherein the bottom support portion includes a cushioning material disposed between the base portion and the glass sheet laminate so as to be separable from the base portion without being bonded to the base portion.
Thus, the cushion material is not bonded, and therefore, the glass plate can be prevented from being contaminated by the adhesive. Further, since the cushion material can be separated, the cushion material can be easily replaced, and the maintainability is improved.
In the above configuration, it is preferable that: the bottom side support portion supports the bottom side of the glass plate laminate so that both end portions in the width direction of the bottom side of the glass plate are exposed from the support surface of the bottom side support portion.
Thus, both ends in the width direction of the bottom edge of the glass plate, that is, corners on both sides in the width direction do not contact the bottom edge support portion. As a result, the corner of the glass sheet can be prevented from being caught by the bottom edge support portion and damaging the glass sheet during conveyance.
In the above configuration, it is preferable that: the bottom support portion further includes a cardboard disposed between the cushion material and the glass plate laminate so as to be separable from the cushion material without being bonded to the cushion material.
If the buffer material is in direct contact with the glass plate, glass frit may adhere to the buffer material. Thus, if the glass frit adheres to the buffer material, it is difficult to completely remove the glass frit. Therefore, glass frit is generated which causes the glass plate to be contaminated with the buffer material, and the buffer material cannot be reused. In contrast, with the above-described configuration, when the cardboard is disposed between the cushioning material and the glass sheet laminate, the cushioning material and the glass sheet do not directly contact each other, and therefore, glass frit can be prevented from adhering to the cushioning material. Therefore, the expensive cushioning material can be repeatedly used in a plurality of deliveries. Here, it is also conceivable to dispose a liner paper between the cushioning material and the glass sheet laminate instead of the cardboard, but the liner paper is easily broken by contact with the glass sheet, and therefore, glass frit may be attached to the cushioning material. In contrast, since the cardboard is less likely to be damaged like a liner paper, adhesion of glass frit to the cushioning material can be reliably prevented.
When the bottom edge support portion is provided with a cardboard, it is preferable that: both ends in the width direction of the bottom edge of the glass plate are exposed from the cardboard, and both ends in the width direction of the cushioning material are exposed from the glass plate.
If the cardboard and the cushioning material are prepared for each glass plate, both ends of the glass plates having different sizes can be freely supported without contacting the bottom support portion, but there is a possibility that the cost increases. On the other hand, if the cushioning material is used such that both ends of the cushioning material are exposed from the glass plate as described above, both ends of the glass plate can be freely supported only by cutting an inexpensive cardboard according to the size of the glass plate without preparing the cushioning material for each glass plate size. Therefore, both ends of the glass plate can be freely supported while suppressing an increase in cost.
In the above configuration, the cushion material preferably contains a foamed resin material.
In this case, the expansion ratio of the foamed resin material is preferably 10 to 40 times.
This makes it possible to achieve both appropriate cushioning properties for the glass sheet and good thickness recovery properties. That is, if the expansion ratio of the foamed resin material is less than 10 times, the foamed resin material tends to be excessively hard, and therefore, the desired cushioning properties may not be obtained. On the other hand, if the expansion ratio of the foamed resin sheet exceeds 40 times, the foamed resin material tends to be too soft, and therefore, the glass plate may be stretched during the packaging operation, which makes handling difficult, or the thickness recovery property may be deteriorated, which makes recycling difficult. Therefore, if the expansion ratio is within the above numerical range, such a disadvantage can be avoided.
In addition, the cushioning material preferably contains a foamed resin material and further contains a rubber material.
Thus, the cushioning material contains the foamed resin material and the rubber material, and can absorb various impacts and vibrations corresponding to the respective impact and vibration absorbing performance.
The glass plate package according to the present invention, which is created to solve the above problems, is characterized in that a glass plate laminate is packaged on a pallet for packaging glass plates, which is appropriately provided with the above configuration.
This makes it possible to enjoy the same operational effects as those of the corresponding configurations described above.
Effect of the utility model
As described above, according to the present invention, it is possible to provide a pallet for packing glass sheets and a glass sheet package body which prevent contamination of glass sheets and have excellent maintainability.

Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the attached drawings.
(first embodiment)
As shown in fig. 1 and 2, a glass plate package 1 according to a first embodiment includes: a glass sheet laminate 2 and a pallet 3 for packing glass sheets.
The laminate 2 is formed by alternately laminating a plurality of glass plates G and protective sheets P in a vertical posture (in the present embodiment, in an inclined posture). In the present embodiment, both the glass sheet G and the protective sheet P are formed in a rectangular shape, and the protective sheets P are disposed on the foremost surface side and the rearmost surface side of the laminate 2.
The weight of the laminate 2 is, for example, 200kg to 3800 kg. The number of the glass sheets G is, for example, 200 to 400. The size of the glass plate G is, for example, 730mm × 920mm to 2250mm × 2600mm, and the thickness of the glass plate G is, for example, 300 μm to 1100 μm. The glass plate G is, for example, a glass substrate for a flat panel display.
The protective sheet P is, for example, a liner paper (plain paper pulp paper) or a foamed resin sheet. The protective sheet P is larger in size than the glass sheets G so that the glass sheets G do not directly contact each other. That is, the protective sheet P may be exposed laterally and/or upwardly of the glass sheet G in the width direction. Among them, from the viewpoint of preventing the loading device and the unloading device of the glass sheets G from generating operation errors, it is preferable that the protective sheet P is not exposed below the glass sheets G.
The pallet 3 includes: a base portion 4 for storing the laminate 2 at the upper side, a bottom side support portion 5 for supporting the bottom side of the laminate 2 in a plane, and a rear surface support portion 6 for supporting the rear surface of the laminate 2 in a plane, the base portion 4 being provided with the bottom side support portion 5.
The base portion 4 is formed of a metal frame of, for example, stainless steel, carbon steel, aluminum alloy, or the like.
The bottom support portion 5 includes: a cushion material 7 placed on the upper surface of the base portion 4, and a paper sheet 8 placed on the upper surface of the cushion material 7. In the present embodiment, the cushioning material 7 supports the entire width of the bottom edge of the glass sheet G included in the laminated body 2. The exposed portion of the bottom edge of the protective sheet P exposed on both sides of the glass sheet G may be supported by the cushioning material 7 or may not be supported by the cushioning material 7.
The cushioning material 7 is disposed so as to be separable from the upper surface of the base portion 4 without being bonded to the upper surface of the base portion 4, and the cardboard sheet 8 is disposed so as to be separable from the upper surface of the cushioning material 7 without being bonded to the upper surface of the cushioning material 7. That is, there is no contact layer between the base portion 4 and the cushioning material 7, both the base portion 4 and the cushioning material 7 are in direct contact, and there is no adhesive layer between the cushioning material 7 and the paper sheet 8, both the cushioning material 7 and the paper sheet 8 are in direct contact.
The cushioning material 7 includes: a foamed resin plate (foamed resin material) 9, and a rubber plate (rubber material) 10 placed on the upper surface of the foamed resin plate 9. The foamed resin plate 9 and the rubber plate 10 are laminated so as to be separable from each other without being bonded to each other. That is, there is no adhesive layer between the foamed resin plate 9 and the rubber plate 10, and both the foamed resin plate 9 and the rubber plate 10 are in direct contact. In the present embodiment, the foamed resin sheet 9 and the rubber sheet 10 are each a single sheet of material that is continuous in the width direction of the laminate 2.
The foamed resin plate 9 is formed of, for example, foamed polypropylene, foamed polyurethane, foamed styrene, foamed melamine, or the like as a main material. In the present embodiment, the foamed resin sheet 9 is a foamed polypropylene sheet. The expansion ratio of the foamed resin plate 9 is preferably 10 to 40 times. The thickness of the foamed resin plate 9 is preferably 10mm to 30mm, for example.
The rubber sheet 10 is made of, for example, natural rubber, and has a type A durometer hardness of 50 to 70. The thickness of the rubber sheet 10 is preferably, for example, 2mm to 10 mm. In this way, by including the foamed resin plate 9 and the rubber plate 10 in the cushioning material 7, it is possible to absorb a large impact and vibration corresponding to the respective impact and vibration absorbing performance. Further, the rubber sheet 10 also has an effect of reducing the compression deformation of the foamed resin sheet 9. From the viewpoint of efficiently absorbing the shock and vibration, the thickness of the rubber sheet 10 is preferably smaller than the thickness of the foamed resin sheet 9. The rubber sheet 10 may be omitted.
The sheet 8 is formed of a sheet such as a small sheet, and includes a form of a corrugated board formed by making the sheet into a multi-layer structure. In the present embodiment, the cardboard 8 is a single plate continuous in the width direction of the stacked body 2. In the case where the paperboard 8 has a single-layer structure, the thickness of the paperboard 8 is preferably, for example, 0.5mm to 2 mm. The cardboard 8 is in direct contact with the bottom edge of the glass sheet G included in the laminate 2, and serves to protect the cushioning material 7 from the glass frit. That is, for example, the cardboard 8 is discarded when it is used once during transportation, and the cushioning material 7 (particularly, the foamed resin sheet 9) is used a plurality of times during transportation and is replaced when the cushioning performance (such as recovery of thickness) is reduced. The cardboard 8 is cheaper than the cushioning material 7, and therefore, even every replacement does not cause a significant increase in cost. Note that the cardboard may be omitted.
The back support portion 6 includes: a back surface portion 11 rising from the base portion 4, and a cushioning material 12 provided on the front surface of the back surface portion 11. In the present embodiment, the cushion material 12 supports the entire back surface of the glass sheet G included in the laminated body 2. The exposed portion of the protective sheet P exposed from the glass sheet G may be supported by the cushioning material 12 or may not be supported by the cushioning material 12.
The cushioning material 12 is laminated so as to be separable from the front surface of the back surface portion 11 without being adhered to the front surface of the back surface portion 11. That is, there is no adhesive layer between the back surface portion 11 and the cushioning material 12, and both the back surface portion 11 and the cushioning material 12 are in direct contact with each other. The movement of the cushioning material 12 can be restricted by providing the rear surface portion 11 with a protrusion and providing the cushioning material 12 with a hole portion that fits into the protrusion.
The cushion material 12 is formed of, for example, a rubber sheet, a foamed resin sheet, or a laminate thereof. Examples of the foamed resin sheet include those formed mainly of foamed polypropylene, foamed polyurethane, foamed styrene, foamed melamine, and the like. In the present embodiment, the cushion material 12 is a foamed polypropylene sheet.
The upper surface of the bottom side support portion 5, that is, the upper surface of the cardboard sheet 8, is inclined at a predetermined angle θ 1 (for example, 5 ° to 25 °) with respect to the horizontal direction in a direction moving upward with separating from the back side support portion 6. The front surface of the rear support portion 6, that is, the front surface of the cushion material 12, is inclined at a predetermined angle θ 2 (for example, 5 ° to 25 °) with respect to the vertical direction in a direction moving rearward with moving away from the bottom support portion 5. At this time, the front surface of the rear surface support portion 6 is, for example, substantially perpendicular to the upper surface of the bottom side support portion 5.
The package 1 configured as described above is shipped (transported) in a state where the stacked body 2 is fixed to the pallet 3 by a predetermined fixing mechanism, for example. The fixing mechanism is not particularly limited, and as shown in fig. 3, a fixing mechanism including a belt 13 that binds the laminate 2, a pressing member 14 disposed between the belt 13 and the front surface of the laminate 2, and a side stopper 15 disposed between the belt 13 and the side portion of the laminate 2 may be used. For example, as shown in fig. 1, in a state where the stacked body 2 is accommodated at a predetermined position on the pallet 3 in the vertical posture, both ends in the longitudinal direction of the belt 13 are hooked on hooks 16 provided on the rear surface support portion 6, and in a double state, the belt 13 is fixed to the front surface of the pressing member 14 in a state where it is fastened by a ratchet or the like, not shown. Thereby, the stacked body 2 is fixed to the pallet 3 in a state where the movement of the stacked body 2 in the front-rear left-right direction is restricted.
In this case, as shown in fig. 3, the frame plate 17 may be placed on the foremost surface side of the laminated body 2, and the frame plate 17, the laminated body 2, and the pressing member 14 may be pressed against the back surface support portion 6 by the belt 13. In order to prevent dust from adhering to the laminate 2, the laminate 2 may be covered with a protective bag or wrapped with a protective film.
According to the pallet 3 and the package 1 having the above-described configuration, since the bottom support portion 5 and the back support portion 6 do not use an adhesive, it is possible to reliably prevent the glass sheets G included in the laminate 2 from being contaminated by the adhesive. Here, since a contamination source derived from the adhesive is likely to be generated by vibration, impact, or the like, the above-described configuration in which the adhesive is not used is particularly useful for the bottom edge support portion 5.
Further, since the cushion material 7 of the bottom side support portion 5 and the cushion material 12 of the back side support portion can be separated from each other, when the cushion performance of the cushion material 7 and the cushion material 12 is lowered, only the cushion material 7 and the cushion material 12 can be easily replaced. Here, since the load of the laminated body 2 is easily applied and the cushioning performance of the cushioning material 7 (particularly, the foamed resin plate 9) is easily lowered, the above-described configuration in which only the cushioning material 7 (the foamed resin plate 9 and/or the rubber plate 10) can be easily replaced with respect to the bottom side support portion 5 is particularly useful.
Further, since the cushion material 7 of the bottom side support portion 5 and the cushion material 12 of the back side support portion 6 can be separated from each other, even when the size of the glass sheet G is changed, the degree of freedom of the arrangement of the cushion material 7 and the cushion material 12 is high, and therefore, it is easy to realize an optimum support method according to the size of the glass sheet G.
(second embodiment)
As shown in fig. 4 and 5, the glass plate package 1 according to the second embodiment differs from the glass plate package 1 according to the first embodiment in that: the bottom support portion 5 is structured. Hereinafter, only the differences from the first embodiment will be described, and the same reference numerals are given to the common points with the first embodiment, and redundant description will be omitted.
As shown in fig. 4 and 5, in the glass plate package 1 according to the second embodiment, the width-direction dimension of the bottom support portion 5 is smaller than the width-direction dimension of the glass plates G included in the laminate 2. That is, the corner portions (both end portions in the width direction of the bottom side) of the bottom side of the glass sheet G are exposed laterally from the bottom side support portion 5. Here, the width-direction dimension of the bottom support portion 5 means: the width dimension of the portion of the bottom side support portion 5 that directly contacts the bottom side of the glass sheet G (the support surface of the bottom side support portion 5). That is, the present embodiment refers to the width-direction dimension of the sheet 8. In the present embodiment, the widthwise central portion of the bottom edge of the glass sheet G excluding the corner portions is continuously supported in the width direction by the bottom edge support portion 5. Here, the width direction may be a traveling direction during transportation. In the present embodiment, the support surface of the bottom support portion 5 is the uppermost surface of the bottom support portion 5.
Thus, the corner portion of the bottom side of the glass sheet G does not contact the bottom side support portion 5. As a result, the corner of the bottom edge of the glass sheet G can be prevented from being caught by the bottom edge support 5 and damaging the glass sheet G during transportation.
As shown in the second embodiment, when the corner portion of the bottom side of the glass sheet G is exposed from the support surface of the bottom side support portion 5, the expansion ratio of the foamed resin sheet 9 is preferably 10 to 40 times, and more preferably 20 to 40 times. When the expansion ratio is 10 to 40 times, the glass sheet can have both appropriate cushioning properties and good thickness recovery properties as described above. When the corner portion of the bottom side of the glass sheet G is exposed from the bottom side support portion 5, the glass sheet G is likely to move due to vibration or impact during conveyance. When the expansion ratio is 20 times or more, the absorption of vibration and impact is improved, and the movement of the glass sheet G can be reduced, so that the increase in contamination of the glass sheet G can be suppressed.
The width D of the corner portion of the bottom side of the glass sheet G exposed from the support surface (the cardboard sheet 8 in the present embodiment) of the bottom side support portion 5 is preferably 10mm to 50mm, for example. If the exposure width D is less than 10mm, if the positioning accuracy of the packaging device in which the glass sheets G and the protective sheets P are alternately stacked on the pallet 3 is insufficient, the corner portion of the bottom edge of a part of the glass sheets G may contact the bottom edge support portion 5. On the other hand, as the exposure width D becomes larger, the glass sheet G tends to be moved by vibration or impact during conveyance, and contamination of the glass sheet G tends to increase, and therefore, the exposure width D is preferably small, and is preferably 50mm or less, more preferably 40mm or less, and most preferably 30mm or less.
(third embodiment)
As shown in fig. 6 and 7, the glass plate package 1 according to the third embodiment differs from the glass plate package 1 according to the second embodiment in that: both ends in the width direction of the bottom edge of the glass plate G are exposed from the cardboard 8, and both ends in the width direction of the cushioning material 7 are exposed from the glass plate G.
In other words, while the second embodiment illustrates a case where the width direction dimensions of the cardboard 8 and the cushioning material 7 are smaller than the width direction dimension of the glass sheet G (see fig. 4 and 5), the width direction dimension of the cardboard 8 is smaller than the width direction dimension of the glass sheet G, and the width direction dimension of the cushioning material 7 is larger than the width direction dimension of the glass sheet G in the third embodiment.
If the cardboard 8 and the cushioning material 7 are prepared individually for each size of the glass sheets G, both ends of the glass sheets G can be freely supported without bringing the corner portion of the bottom side of the glass sheets G having different sizes into contact with the bottom side support portion 5, but the cushioning material 7, which is expensive compared to the cardboard 8, needs to be provided in a plurality of kinds, and the cost may increase. On the other hand, as described in the present embodiment, when the cushioning material 7 in which both end portions of the cushioning material 7 are exposed from the glass plate G is used, both end portions of the glass plate G can be freely supported only by cutting the inexpensive cardboard 8 according to the size of the glass plate G without preparing the cushioning material 7 in accordance with the size of the glass plate G one by one. Therefore, both ends of the glass plate G can be freely supported while suppressing an increase in cost.
The present invention is not limited to the configuration of the above embodiment, and is not limited to the above operation and effect. The present invention can be variously modified within a scope not departing from the gist of the present invention.
In the above embodiment, the case where the rubber sheet 10 is disposed on the upper surface of the foamed resin sheet 9 as the cushioning material 7 of the bottom side support portion 5 has been described, but the rubber sheet 10 may be disposed only on the lower surface of the foamed resin sheet 9, or the rubber sheets 10 may be disposed on the upper and lower surfaces of the foamed resin sheet 9, respectively. When the rubber plates 10 are disposed on the upper and lower surfaces of the foamed resin plate 9, the rubber plates 10 disposed on the upper surface side of the foamed resin plate 9 and the rubber plates 10 disposed on the lower surface side of the foamed resin plate 9 may be different in thickness and material.
In the above embodiment, the foamed resin plate 9 is described as being formed of one foamed resin plate 9, but the foamed resin plate 9 may be formed by laminating a plurality of foamed resin plates. In this case, the plurality of foamed resin sheets 9 may be directly laminated or laminated with a rubber material interposed therebetween as long as they can be separated from the base portion 4 without being bonded to the base portion 4.
In the above embodiment, the bottom edge of the glass sheet G is continuously supported by the bottom edge support portion 5 in the width direction, but a plurality of portions of the bottom edge of the glass sheet G may be intermittently supported by the bottom edge support portion 5 in the width direction. When the support is intermittently performed, the cardboard 8, the foamed resin sheet 9, and the rubber sheet 10 are long, and therefore, their intended functions may be impaired due to positional deviation during the loading process or the transportation. From the viewpoint of preventing this, it is preferable that the bottom edge of the glass sheet G is continuously supported by the bottom edge support portion 5 in the width direction.
