Description

  The present invention relates to a glass plate packing pallet used for packing a plurality of glass plates, and a technology for improving a glass plate packing body configured by packing a plurality of glass plates on the glass plate packing pallet. About.

  For example, with the increase in the size of glass substrates for flat panel displays, the packaging of glass substrates has become the mainstream of stacking with slip sheets, and inclined packing pallets have been proposed for some time. The packing pallet includes a base portion in which a glass plate laminated body in which a plurality of glass plates are stacked in a vertical posture via a slip sheet is accommodated upward, and the glass plate stack standing from the base portion. A back support portion for supporting the back side of the body, and a glass support surface is formed on the back support portion for supporting the glass plate laminated body in contact with the back slip sheet. As a material of the glass support surface in the back support part of the conventional packing pallet, generally, an elastic resin or a foamable resin has been used (for example, see Patent Documents 1 to 4).

  By the way, when packing a conventional glass plate, the slip sheet is arranged on the front side of the glass support surface of the packing pallet, and then the glass plate is arranged on the front side. Thereafter, the interleaving paper and the glass plate are alternately arranged up to a predetermined amount to constitute a glass plate laminate, and thereafter fixed by the pressing member. Thereby, a glass plate package is comprised.

  However, the conventional glass plate package using a packaging pallet has a drawback that the glass plate laminate easily moves with respect to the glass support surface during transportation, and the glass plate laminate tends to be laterally displaced. When such a horizontal shift of the glass plate laminate occurs, there may be a problem that it cannot be put into the production line at the time of use.

  As a countermeasure against the lateral displacement, it is conceivable that a side stopper is separately attached to the side of the back support portion of the packing pallet, and the lateral movement of the glass plate laminate is restricted by the side stopper. However, when such a side stopper is attached, there has been a problem that work for packing and unpacking, and labor for member management increase.

  In view of the above circumstances, the present invention creates a glass plate packing pallet and a glass plate packing body that can suppress lateral displacement of the glass plate laminate during transportation of the glass plate packing body without separately attaching a side stopper. This is a technical issue.

  As a result of intensive studies, the present inventor has found that the lateral displacement of the glass plate laminate as described above occurs in the following manner. That is, since a frictional force is relatively large between the glass plate and the slip sheet, almost no slip (lateral deviation) occurs in the glass plate laminate. Then, slippage (lateral deviation) occurs mainly between the last sheet (most rear side) of the glass sheet laminate and the glass support surface. That is, the glass plate laminate is integrated and moves laterally with respect to the glass support surface, resulting in lateral displacement.

  The glass plate packing pallet according to the present invention, which was created based on the above-described knowledge, is a base on which a glass plate laminate in which a plurality of glass plates are laminated in a vertical posture through a slip sheet is accommodated upward. A base part and a back support part that stands up from the base part and supports the back side of the glass plate laminate, the glass support being in contact with the back slip sheet on the back support part. In the glass plate packing pallet on which the glass support surface to be supported is formed, the static friction coefficient with the slip sheet is 30% or more of the area of the contact area that contacts the glass plate via the slip sheet on the glass support surface. It is characterized by the specific friction region being 0.30 or more.

  In this case, if the specific friction area is less than 30% of the area of the contact area, the frictional force of the glass support surface against the interleaf is insufficient, and a lateral shift of the glass plate laminate may occur. is there. On the other hand, even if the static friction coefficient with respect to the slip sheet in the specific friction region is less than 0.30, the frictional force with respect to the slip sheet on the glass support surface is still insufficient, and the lateral displacement of the glass plate laminate may occur. There is.

  On the other hand, if the specific friction area is 30% or more of the area of the contact area and the static friction coefficient with respect to the interleaving paper in the specific friction area is 0.30 or more as in the above configuration, the glass support surface The frictional force on the slip sheet becomes sufficient, and this frictional force becomes a force for holding the slip sheet, whereby the glass plate laminate can be suppressed from moving integrally with the glass support surface. Therefore, in the glass plate packing pallet of the present invention, it is possible to suppress the lateral displacement of the glass plate laminate during transportation of the glass plate package without separately attaching a side stopper to the glass plate packing pallet. .

  Moreover, in order to suppress the lateral displacement of the glass plate laminate, it is preferable that the entire contact area of the glass support surface be a specific friction region. ) May be difficult to peel off from the glass support surface. This is because the adhesion between the last-stage glass plate and the glass support surface may be enhanced through the last-stage slip sheet having air permeability.

  On the other hand, in the said structure, it is preferable to make 30%-70% of the area of the said contact area | region into the said specific friction area | region. Thus, if the specific friction region is 70% or less of the area of the contact region, the adhesion between the last glass plate and the glass supporting surface is weakened, and the last glass plate of the glass plate laminate is made of glass. It is possible to avoid a situation where it is difficult to peel off from the support surface.

  In any one of the configurations described above, the specific friction region is preferably made of polyvinyl chloride.

  If it is this structure, it is easy to make the static friction coefficient with respect to the slip sheet of a specific friction area | region into 0.30 or more. In this configuration, it is preferable that the specific friction region is subjected to antistatic treatment. Thereby, it can suppress that the particle which has a bad influence on manufacture of the product which uses glass plates, such as a flat panel display, adheres to a glass plate.

  In any one of the configurations described above, it is preferable that a central portion in the contact area is the specific friction area.

  If it is this structure, the adhesive force between the glass plate of the last stage and the peripheral part of a glass support surface will become weak. When the last glass plate is peeled off, one end of either the vertical direction or the horizontal direction of the glass plate is first separated from the contact area. Therefore, if the adhesion between the last glass plate and the peripheral edge of the contact area is weakened, even if the glass plate is peeled off from either one of the longitudinal and lateral ends of the glass plate, the last glass plate It becomes easy to peel off. Thereby, it is possible to have both the ease of peeling off the last glass plate and the prevention of lateral displacement.

  In any one of the configurations described above, it is preferable that a region that is a center point in the horizontal direction in the contact region and includes a point at a position that is 1/4 of the total length in the vertical direction from the lower end is set as the specific friction region. .

  With this configuration, at least a part of the specific friction region is located below the contact region. Since the weight of the glass plate is increased in the contact area as it moves to the lower side of the contact area, even if the material of the contact area is the same, more frictional force can be obtained in the lower area of the contact area. Therefore, when the specific friction region is located at the lower side of the contact region, even if the entire area of the specific friction region is the same, the effect of preventing the lateral displacement of the glass laminate can be obtained efficiently.

  In addition, the above-described effects can be obtained if the glass plate package is formed by packing the glass plate laminate on the glass plate packing pallet having any one of the above configurations. It becomes a glass plate package.

  As described above, according to the present invention, it is possible to suppress the lateral displacement of the glass plate laminate during transportation of the glass plate package without separately attaching a side stopper. Further, if the side stopper is not required, it can contribute to reduction of time and effort at the time of packing and unpacking.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic perspective view showing a glass plate package according to an embodiment of the present invention. The glass plate package 1 is configured by packing a glass plate laminate 3 on a glass plate packing pallet 2. The glass plate package 1 includes a glass plate packing pallet 2 and a glass plate laminate 3 as main components.

  In the glass plate laminate 3, a plurality of rectangular or square glass plates G are laminated in a vertical posture through interleaving paper I. And the interleaf paper I is arrange | positioned at the backmost side of the glass plate laminated body 3. FIG. That is, the back surface of the glass laminate 3 is the interleaf paper I.

  The weight of the glass plate laminate 3 is, for example, 200 kg to 3800 kg. The number of glass plates G is, for example, 200 to 400. Moreover, the magnitude | size of the glass plate G is 1000 mm x 1200 mm-2200 mm x 2500 mm, for example. Moreover, the thickness of a glass plate is 300 micrometers-0.7 mm, for example. The glass plate G is a glass substrate for flat panel displays, for example. The interleaf paper I used for the glass plate laminate 3 is, for example, pure pulp paper. The size of the interleaf paper I is usually larger than the glass plates G and is arranged so that the glass plates G are not in direct contact with each other. The glass plates G are arranged at the same position in the vertical direction and the horizontal direction.

  As shown in FIGS. 1 and 2, the glass plate packing pallet 2 includes a base part 4, a back support part 5, a bottom support part 6, and a holding part 7 as main components. As for the base part 4, the glass plate laminated body 3 is accommodated upwards. And the back surface support part 5 stands up from the base part 4, and supports the back side of the glass plate laminated body 3. FIG. The bottom support portion 6 supports the lower end portion (the bottom portion of the glass plate G) of the glass plate laminate 3 on the base portion 4. The bottom support 6 is a plurality of (three in the illustrated example) plate materials as cushioning materials, and the material is, for example, foamed polypropylene.

  The back support portion 5 is formed with a facing portion 5 a that faces the back surface of the glass plate laminate 3. A back plate 8 is attached to the facing portion 5a in a region excluding its upper edge and side edges. As shown in FIG. 3, the size of the back plate 8 is slightly smaller than the size of the facing portion 5a. The side (front side) of the back plate 8 facing the back side of the glass plate laminate 3 is a glass support surface 8a that supports the glass plate laminate 3 in contact with the interleaf paper I on the back side (most back side). It is. In this embodiment, the magnitude | size of the glass plate G of the glass plate laminated body 3 is a little smaller than the magnitude | size of the glass support surface 8a. Therefore, as shown by the two-dot chain point in FIG. 3, the contact region R that contacts the glass plate G via the slip sheet I on the glass support surface 8a is smaller than the glass support surface 8a, and part of the glass support surface 8a. It has become. However, the present invention is not limited to this, and the size of the glass plate G may be the same as the size of the glass support surface 8a, and the contact region R may be the entire glass support surface 8a. However, if the glass support surface 8a is smaller than the size of the glass plate G, the end portion of the glass plate G protrudes from the glass support surface 8a when the glass plates G are laminated.

  Further, the upper surface of the bottom support 6 is a glass support 6 a that supports the lower end of the glass plate laminate 3. The glass support surface 8a of the back support part 5 is inclined, for example, 5 ° to 25 ° rearward with respect to the vertical direction. Further, the glass support surface 8 a of the back support portion 5 forms an angle of, for example, 90 ° to 110 ° with respect to the glass support surface 6 a of the bottom support portion 6.

  The holding part 7 presses and holds the glass plate laminate 3 toward the back support part 5 side. The holding part 7 is roughly divided into a pressing member 7a pressed against the front side of the glass plate G, a guide member 7b that holds both ends of the pressing member 7a in a slidable direction in the glass plate G, and a pressing member 7a. It is comprised from the fixing means 7c which controls the slide with respect to this guide member 7b in arbitrary positions.

  The guide members 7b are attached in pairs to the left and right side wall portions 5b of the back support portion 5, and in the present embodiment, the pair of left and right guide members 7b are spaced apart from each other by 2 above and below the side wall portion 5b. It is assembled. Each guide member 7b has a base end portion pivotally supported by a pin 7b1 and a rod-like portion 7b2 on the distal end side. Each rod-like portion 7b2 extends in a position forward of the glass support surface 8a along the stacking direction of the glass plates G placed on the base portion 4 (a direction substantially orthogonal to the glass support surface 8a). Yes. The guide member 7b is rotatable about the pin 7b1, and as shown in FIG. 2, the guide member 7b can be retracted to a position behind the glass support surface 8a. Thereby, it can suppress that the guide member 7b obstruct | occludes the taking-out operation | work of loading of the glass plate G to the pallet 2 for glass plate packing, and taking-out of the glass plate G from the pallet 2 for glass plate packing.

  The pressing member 7a is a plate-like hollow member that is longer than the width of the glass plate G, and is disposed on the front side of the glass plate G with both ends held by the rod-like portions 7b2 of the guide member 7b. It is being pressed. Specifically, the pressing member 7a is slidably held along the rod-like portion 7b2 by fitting the rod-like portion 7b2 into the fitting holes 7a1 formed at both ends thereof, and the range of the length of the rod-like portion 7b2 The glass plate G can be moved back and forth in the stacking direction.

  Further, in the present embodiment, the fixing means 7c has a lever 7c1 at an intermediate portion in the longitudinal direction of the pressing member 7a, and the operation of the lever 7c1 restricts or cancels the sliding of the pressing member 7a with respect to the rod-like portion 7b2. It is possible. The fixing means 7c can be configured by a known technique described in Patent Document 1, for example. A buffer plate 9 made of, for example, foamed polypropylene is disposed between the frontmost glass plate G of the glass plate laminate 3 and the pressing member 7a.

  As described above, the glass support surface 8 a formed on the back support portion 5 of the glass plate packing pallet 2 has the contact region R that contacts the glass plate G via the interleaf paper I. As shown by cross-hatching in FIGS. 2 and 3, 30% or more of the area of the contact region R is a specific friction region Ra having a static friction coefficient with the interleaf paper I of 0.30 or more. In this case, if the specific friction area Ra is less than 30% of the area of the contact area R, the frictional force of the glass support surface 8a with respect to the interleaf paper I becomes insufficient, and the lateral displacement of the glass plate laminate 3 may occur. There is sex. On the other hand, even if the static friction coefficient with respect to the interleaving paper I in the specific friction area Ra is less than 0.30, the frictional force with respect to the interleaving paper I of the glass support surface 8a is still insufficient, and the lateral displacement of the glass plate laminate 3 is reduced. May occur. However, in the present embodiment, as described above, 30% or more of the area of the contact region R is the specific friction region Ra having a static friction coefficient with the slip sheet I of 0.30 or more. Such a problem does not occur.

  Further, the specific friction area Ra is preferably 70% or less of the contact area R, for example. When the specific friction area Ra exceeds 70% of the contact area R, the adhesion between the glass plate G closest to the glass support surface 8a (the last stage) and the glass support surface 8a increases, and this glass plate G is supported by the glass. There is a possibility that it will be difficult to peel off the surface 8a. However, when the specific friction area Ra is 70% or less of the contact area R, such a problem does not occur.

  Moreover, specific friction area | region Ra is located in the downward part or center part in contact area R, for example, and is located in a center part (non-periphery part) in FIG. Further, for example, as shown in FIG. 4A, the specific friction region Ra may be located in a region including the point A. Here, the point A is a point in the center in the horizontal direction in the contact region R, and is a point at a position that is 1/4 of the total length in the vertical direction from the lower end. In FIG. 4A, the specific friction region Ra is located in the region from the vicinity of the center in the vertical direction of the contact region R to the slightly lower end side. That is, at least a part of the specific friction area Ra is located below the contact area. Further, the specific friction area Ra is not provided at the upper edge or the lower edge of the contact area R. Of course, it is not limited to this, For example, as shown to FIG. 4 (B), specific friction area | region Ra may be located in the area | region which does not contain the point A. FIG.

  3 and 4, the specific friction region Ra is a single region. For example, as shown in FIG. 5, the specific friction region Ra is provided at a plurality of locations in the contact region R. The total area of the plurality of specific friction regions Ra may be 30% or more of the area of the contact region R.

  In FIG. 5A, the specific friction areas Ra are arranged in a plurality of stages, the number of the specific friction areas Ra at the lowest stage is the largest, and the area including all of these areas is slightly below the contact area R. To position. Specifically, the specific friction regions Ra having the same area are arranged in three stages, three in the upper and middle stages, and four in the lower stage. The region including the whole is rectangular, and the interval between the lower specific friction regions Ra is narrower than the interval between the specific friction regions Ra in the other steps.

  Also in FIG. 5B, the specific friction areas Ra are arranged in a plurality of stages, but the number of specific friction areas gradually increases from the upper stage toward the lower stage, and the area including all of these areas is triangular. . Specifically, specific friction regions Ra having the same area are arranged in three stages, one in the upper stage, three in the middle stage, and five in the lower stage. The interval between the lower specific friction regions Ra is the same as the interval between the specific friction regions Ra in the middle. 5A and 5B, many specific friction regions Ra are located below the entire contact region R, and the number of the lowest stage is the largest.

  The specific friction region Ra is, for example, a non-foamed resin, and in this embodiment, the specific friction region Ra is made of polyvinyl chloride having a mirror surface. However, the present invention is not limited to this, and it is sufficient that the coefficient of static friction with the interleaf paper I is 0.30 or more. In the present embodiment, the contact region R is subjected to antistatic treatment. Further, the contact region R other than the specific friction region Ra is made of, for example, foamed polypropylene, but is not limited thereto.

  The glass plate pallet 2 and the glass plate package 1 configured as described above can enjoy the following effects.

  Since the specific friction area Ra is 30% or more of the area of the contact area R and the static friction coefficient of the specific friction area Ra with respect to the interleaving paper I is 0.30 or more, the friction force of the glass support surface 8a with respect to the interleaving paper I Is sufficient, and this frictional force is a force for holding the interleaf paper I, whereby the glass plate laminate 3 can be prevented from moving integrally with the glass support surface 8a. Therefore, in the glass plate packaging pallet 2 of the present embodiment, the lateral displacement of the glass plate laminate 3 during the transportation of the glass plate packaging 1 is suppressed without separately attaching a side stopper to the glass plate packaging pallet 2. It becomes possible.

  Moreover, if specific friction area | region Ra shall be 70% or less of the area of contact area | region R, the adhesiveness between the last glass plate G and the glass support surface 8a will be weakened, and the last glass of the glass plate laminated body 3 will be reduced. It is possible to avoid a situation in which the plate G is difficult to peel off from the glass support surface 8a.

  And since specific friction area | region Ra is comprised with the polyvinyl chloride, it is easy to make the static friction coefficient with respect to the interleaving paper I of specific friction area | region Ra 0.30 or more. In addition, since the specific friction region Ra is subjected to the antistatic treatment, it is possible to prevent particles that adversely affect the manufacture of a product using the glass plate G such as a flat panel display from adhering to the glass plate.

  Further, for example, when the central portion in the contact region R is the specific friction region Ra, the adhesion between the last glass plate G and the peripheral portion of the contact region R is weak, and therefore the glass plate G is peeled off. First, either one of the longitudinal direction and the lateral direction of the glass plate G is first separated from the contact region R. Therefore, if the adhesion between the last glass plate G and the peripheral edge of the contact region R is weak, even if the glass plate G is peeled off from either one of the longitudinal and lateral ends of the glass plate G, the last glass It becomes easy to peel off the glass plate G. Thereby, it is possible to have both ease of peeling off the last glass plate G and prevention of lateral displacement.

  Moreover, since the weight of the glass plate G increases in the contact area R as it moves to the lower side of the contact area R, the lower area of the contact area R is more even if the material of the contact area R is the same. A frictional force is obtained. Therefore, when the specific friction region Ra is located partly or entirely below the contact region R, even if the entire area of the specific friction region Ra is the same, it is possible to effectively prevent the lateral displacement of the glass laminate. Can be obtained.

  In addition, in order to make it easy to peel off the last glass plate G, a groove (slit) may be provided from the inside of the contact region R to the outside of the contact region R. Thereby, since it becomes easy to supply air between the glass plate G of the last stage and the contact area | region R, it becomes easy to peel off the glass plate G of the last stage.

  This inventor evaluated the pallet for glass plate packaging which concerns on the Example of this invention. In this pallet for packing glass plates, as the back plate 8, polyvinyl chloride (hereinafter referred to as PVC) whose whole was subjected to antistatic treatment was used. That is, 100% of the area of the contact region R was defined as a specific friction region (PVC subjected to antistatic treatment). Other than that, it is the same structure as the said embodiment.

  In addition, as a comparative example, the back plate 8 is made of 3 times expanded polypropylene (hereinafter referred to as PP) which is generally used for conventional pallets, and otherwise, the glass plate packaging pallet 2 of the embodiment. The same configuration was evaluated.

  Table 1 shows the static friction coefficients of PVC and 3-fold expanded PP with respect to the interleaving paper. These static friction coefficients were obtained as follows. As shown in FIG. 6, a slip sheet I (4 × 5 cm) is placed on a plate P made of the same material as the back plate 8 in a horizontal state, and a 1 kg weight D is placed on the slip sheet I. One end of the wire W is attached to the slip sheet I in this state, and the other end of the wire W is attached to the hook of the spring S. The direction of the wire W is changed by the pulley B in the middle of the wire W, extending horizontally from the interleaf I to the pulley B, and extending upward from the pulley B to the spring S alone. Then, by moving the main body of the spring S in the upward direction, the maximum force applied while the slip sheet I is stationary is measured. From this measured force, the static friction coefficient was determined by the following equation: μ = f / X (μ: static friction coefficient, f: maximum static friction force, X: normal force (weight of weight)).

  Evaluation was performed as follows. The interleaving paper I and the glass plate G are alternately arranged on each of the glass support surfaces 8a in the glass plate packing pallet 2 of the example and the comparative example, and the buffer plate 9 (three times foaming) is placed on the last glass plate G. After being disposed, the glass plate package 1 was constituted by fixing with the pressing member 7a. The glass plate G was 300 sheets. And after measuring the position of the glass plate G in advance and carrying out truck transportation of about 1200 km, the position of the glass plate G was measured again, and the amount of lateral deviation before and after transportation was determined.

  The evaluation results are shown in Table 2. As can be understood from Table 2, the example (PVC back plate) is more effective in suppressing the lateral displacement of the glass plate G than the comparative example (triple expanded PP back plate). It was.

  Further, the present inventor performed the same evaluation as in Example 1 by changing the ratio of PVC used for the back plate 8 (ratio of the specific friction area Ra in the contact area R). At the same time, the ease of peeling off the glass plate G at the last stage (most back plate side) was also evaluated. In addition, the area | region (specific friction area | region Ra) which uses PVC was made into the downward direction of the contact area | region R of the backplate 8, and the other area | region was made into 3 times foaming PP.

  The evaluation results are shown in Table 3. In the evaluation of Table 3, the symbol ◯ means that it is very good, and the symbol Δ means that it is somewhat good. From Table 3, when the ratio of the PVC used for the back plate 8 (the ratio of the specific friction area in the contact area) is 30 to 70%, it is used for glass sheet packaging that has both prevention of lateral displacement and easy peeling of the glass sheet. It turned out to be Pallet 2.

  The present invention is not limited to the above description, and various modifications are possible within the scope of the technical idea. For example, in the above description, the specific friction area Ra is located at the lower part or the center part in the contact area R, but may be located at the side part or the upper part.
