Description

Bundling container, packing body and packing method

The present invention relates to a packaging container in which a plurality of glass sheets are mounted in a longitudinal direction, and a packaging body and a packaging method using the packaging container.

In recent years, the demand for large glass sheets for glass for FPD (Flat Panel Display) has been increasing. As a mechanism for transporting such a large-sized glass plate, for example, a glass plate packing case in which each glass plate is fixed in a state in which a plurality of glass plates are arranged in a row is known (for example, see Patent Document 1).

The glass plate packing case is configured to have a bottom support plate having a base on which the glass plate is placed, and supporting the lower end portion of the glass plate on the mounting surface of the base; and a back support plate. Support the thickness direction of the glass plate.

When the glass plate is mounted on such a bottom support plate and a back support plate, spacer paper is usually sandwiched between the glass plates in order to prevent damage of the glass plates in direct contact with each other during conveyance. At this time, in order to prevent the spacer paper from being adsorbed by the mechanical arm during the unloading of the glass plate and to be easily removed from the glass plate, the spacer paper is extended from the upper end of the glass plate, and this is used as a suction for holding by the mechanical arm. The holding part.

However, after the glass plate is mounted on the bottom support plate and the back support plate and conveyed, when the glass plate is unloaded, the holding portion is sucked and held by the robot arm as described above, and the spacer paper is removed from the glass plate. However, if the holding portion of the spacer paper, that is, the portion extending from the upper end of the glass sheet is not uniformly inclined, a part is not erected obliquely, or a part of the holding portion is inclined toward the back support plate side and the other holding portion is directed to the back support plate side. When the side of the opposite side is inclined, the positioning of the holding portion with respect to the arm cannot be performed satisfactorily, and the spacer paper cannot be adsorbed and held.

In order to avoid such a defect, it is conceivable to tilt the holding portion in one direction, for example, toward the back support plate side. However, since the back support plate is generally formed higher than the glass plate so as to support the entire surface of the glass plate, the spacer paper disposed on the back support plate side is interfered by the back support plate and cannot be sufficiently inclined. As a result, the positioning of the holding portion of the robot arm cannot be performed satisfactorily, and the spacer paper cannot be adsorbed and held.

Further, in the above-described packaging container, it is preferable that an inclination angle of the inclined surface with respect to the thickness direction of the backing plate is more than 0° and not more than 20°.

Further, in the packaging system of the present invention, the package body of the glass plate in which the plurality of fast glass plates and the spacer paper sandwiched between the glass plates are placed in the packaging container, and the glass plate is supported on the back plate side. In a state of one side, a plurality of glass sheets are placed on the bottom pallet, and the spacer paper is sandwiched between the glass sheets while extending from a predetermined length from the glass sheet to form an extending portion. The extending portion of the spacer paper is uniformly inclined toward the back plate side.

Moreover, the packing method of the present invention is a method of packing a glass plate in which a plurality of glass plates and a spacer paper sandwiched between the glass plates are mounted in the packaging container, and has a step of: making one side of the glass plate In a state in which the side is supported on the backing plate side, a plurality of glass sheets are placed on the bottom pallet, and the spacer paper is held in a state in which a predetermined length is extended from the glass sheet and an extension portion is formed. Between the glass sheets, the extending portion of the spacer paper is inverted to the side of the back sheet and uniformly inclined.

Further, in the above packing method, preferably, when the spacer paper is sandwiched between the glass sheets, the lower end of the spacer paper is formed from the bottom stack The above-mentioned spacer paper is arranged in such a manner that the board is suspended.

Further, according to the package of the present invention, the extending portion of the spacer paper between the glass sheets mounted in the packaging container is uniformly inclined along the inclined surface of the backing plate, so that the extending portion of the arm during unloading (holding portion) The positioning can be performed well, so that the spacer paper can be stably adsorbed and held, and can be reliably removed from the glass plate.

Moreover, according to the packing method of the present invention, since the extending portion of the spacer paper between the glass sheets mounted in the packaging container is uniformly inclined along the inclined surface of the backing plate, the extending portion of the arm during unloading ( The positioning of the holding portion can be performed satisfactorily, so that the spacer paper can be stably adsorbed and held, and can be reliably removed from the glass plate.

Hereinafter, the packing container, the packing body, and the packing method of the present invention will be described, but the present invention is not limited to the embodiments described below.

1A and 1B are views showing a schematic configuration of a package body using the packaging container of the present invention, and Fig. 1A is a front view and Fig. 1B is a side view. Figure 1A, 1B is a packing container, and 2 is a packing body. Each of the packaging container 1 and the packaging body 2 is an embodiment of the packaging container and the packaging body of the present invention. The package 2 includes a bundle container 1 and a glass plate G mounted on the package container 1.

As the glass plate G, a glass substrate for a flat panel display (FPD) such as a liquid crystal display, an electroluminescence display, or a plasma display is intended. Specifically, a rectangular plate-shaped glass substrate having a size of 2,500 mm × 2,200 mm and a thickness of about 0.7 mm was used as the glass plate G. However, the present invention is not limited to the fixation of the glass sheet G of such a size, and can be applied to the fixing of the glass sheets of various sizes and thicknesses. Further, various glass sheets other than the glass substrate for FPD have also been applied.

The packing container 1 is a longitudinally placed packaging container in which a glass sheet G is placed in a longitudinal direction, and is provided with a base 3, a bottom pallet 4 disposed on the base 3, and a backing plate 5. The base 3 is installed on a substantially horizontal surface such as a floor or a cargo bed surface of the vehicle. As shown in FIG. 1A, a plurality of (four in the figure) pullable insertion stacker are formed on the front side and the back side. The opening portion 6 of the claw (not shown). Regarding the side surface of the base 3, it may be opened or may be a closed structure (closed structure in Fig. 1B). Further, the base 3 includes, for example, a steel material, and is preferably stainless steel in consideration of peeling off of the paint when it is considered to be prevented from being carried into the clean room.

The bottom pallet 4 is provided in a rectangular plate shape provided on the upper surface 3a of the base 3, and supports the bottom edge portion of the mounted glass plate G. The bottom pallet 4 is disposed obliquely with respect to the upper surface 3a of the base 3 by providing the front side lower partitioning substrate 7 on the base 3 as shown in FIG. 1B. Also, the bottom pallet 4 is in this embodiment In the state in which the base 3 is oriented in the direction of the arrow X in FIG. 1A in two directions, and the upper surface (inclined surface), that is, the mounting surface of each of the glass sheets G, is formed in the same plane. Configuration. The upper surface of the bottom pallet 4 is substantially flat without forming a groove or the like for inserting the glass sheet G, and if a plurality of pieces of glass can be placed so as to sandwich the spacer paper P between the sheets For the plate G, it may be wavy or rough.

Further, the bottom pallet 4 may be composed of one plate having a width equal to the width of the back plate 5 described below. The bottom pallet 4 is preferably inclined by 5 to 25 degrees, more preferably by 10 to 20 degrees, and particularly preferably by about 18 degrees with respect to the upper surface 3a of the base 3. Thereby, the operator can easily and efficiently perform the positioning operation of the glass sheet G when the glass sheet G is placed. The glass sheets G placed on the upper surface of the bottom pallet 4 are slid toward the back sheet 5 by their own weight, and are in contact with the glass sheet G on the side of the back sheet 5 without causing uselessness between the glass sheets G. gap. Further, the glass plate G placed thereon can be stabilized, and the offset or collapse of the glass plate G can be prevented, and damage or cracking can be prevented. Furthermore, the bottom plate 7 can also be height-adjusted so that the angle of the bottom pallet 4 relative to the upper surface 3a of the base is adjustable.

One side of the back plate 5 is supported and fixed to the support frame 8 provided on the upper surface 3a of the base 3, and the lower end portion is supported and fixed to the bottom pallet 4. The support frame 8 is provided with a support member 9 that is vertically disposed with respect to the upper surface 3a of the base 3, and an inclined frame 10 that is disposed at a predetermined angle with respect to the upper surface 3a of the base 3; A reinforcing frame 11 is disposed between the pillars 9 and the inclined frame 10.

The inclined frame 10 is preferably formed to be opposite to the upper surface of the bottom pallet 4 A plurality of roots are provided on the upper surface 3a of the base plate in a manner of 90° to 100°, more preferably 90° to 95°, and particularly preferably about 90°. Further, the strut 9 is also provided with a plurality of roots corresponding to the tilt frame 10. The reinforcing frame 11 is provided with a plurality of roots on the upper surface 3a of the base 3 and at the central portion of each of the pillars 9 and the inclined frame 10 in the height direction.

Further, the backing plate 5 is attached to the outside of the inclined frame 10 including the support frame 8 having such a configuration, and therefore is inclined at the same angle as the inclined frame 10 with respect to the upper surface of the bottom pallet 4. The backing plate 5 supports a rectangular plate shape which is mounted on one side of the glass plate G which is vertically placed on the bottom pallet 4 and supports it. In the present embodiment, the support of the back plate 5 supporting the side of the glass plate G is supported. The surface 5a is formed in substantially the same size and shape as the glass plate G to be mounted. Therefore, the support surface 5a of the back plate 5 is formed to have substantially the same height as the above-described glass plate G. Further, the height of the glass sheet G is substantially the same, and in the present specification, it means within ±10% of the height of the glass sheet G, preferably within ±5%. For example, even if the support surface 5a of the back sheet 5 is 10% higher than the height of the glass sheet G, the extension portion PE of the spacer paper P is 0° with respect to the upper end surface of the glass sheet G as follows. The front side is flattened, but inclined obliquely upward, so that the support surface 5a of the backing plate 5 does not substantially interfere with the extension portion PE of the spacer paper P.

Further, the backing plate 5 is formed as an inclined surface in which the upper end surface 12 gradually increases toward the back surface 5b of the backing plate 5 from the support surface 5a as shown in FIG. 2A. That is, the height of the support surface 5a of the back sheet 5 of the present embodiment is substantially the same as the height of the glass sheet G, but the upper end surface 12 is not parallel to the thickness direction of the back sheet 5, but is an inclined surface.

The inclination angle θ of the inclined surface (upper end surface 12) with respect to the thickness direction of the backing plate 5 is formed to exceed 0° and not more than 20°. By inclining the angle to the inclined portion PE of the paper P as described below, the slope can be more stably stabilized. Furthermore, in the present embodiment, the upper end surface 10a of the inclined frame 10 that holds the back surface 5b of the back plate 5 is also inclined at the same angle as the upper end surface 12 of the back plate 5, and is formed in the same plane as the upper end surface 12. Configuration.

Further, the width W of the inclined surface (upper end surface 12) of the backing plate 5 from the supporting surface 5a to the back surface 5b is formed to be slightly longer than the length of the extending portion PE of the following partition paper P.

However, the back sheet 5 of the present embodiment is not limited to the above-described size or thickness (the width W of the upper end surface 12), and various sizes or thicknesses can be used. For example, as for the size, the width of the support surface 5a on the side of the glass plate G to be mounted is substantially the same as the height of the glass plate G, and the width in the direction of the arrow X in FIG. 1A may be different from the width of the glass plate G.

In order to prevent damage caused by contact with the glass sheet G when the glass sheet G is mounted, the back sheet 5 and the bottom pallet 4 are provided with rubber or hard on the surface (the side contacting the glass sheet G). A cushioning material (not shown) such as a foaming resin. The cushioning material is sufficiently thinner than the thickness of the backing plate 5, and is attached to the backing plate 5, the bottom pallet 4, and the like by adhesion or the like. Here, the cushioning material may be temporarily fixed only to the backing plate 5 or the bottom pallet 4, and may be detachably provided.

The glass plate G is, for example, about 200 to 300 pieces overlapped in the front-rear direction of the bottom pallet 4, that is, in the direction orthogonal to the support surface 5a of the backing plate 5, and is vertically stacked. Further, a rectangular sheet of space P is sandwiched between each of the glass sheets G.

The spacer paper P is used to prevent the glass sheets G from directly contacting each other, and is used to prevent damage to the glass sheets G from being interfered with each other during the conveyance process.

As the spacer paper P, in order to prevent the resin component in the spacer paper P from being transferred to the surface of the glass sheet G to produce a paper pattern or a blackening or stain, the smoothness of the paper (JIS P 8119, 1976) is 20 seconds or less. Preferably, it is a rough surface of 18 seconds or less. Thereby, the contact area with respect to the surface of the glass plate G is reduced, and the transfer of a resin component is suppressed. Moreover, it is preferable to maintain the surface of the glass sheet G by the composite action with the above-mentioned rough surface by adjusting the resin component to 0.1% by mass or less, preferably 0.05% by mass or less (JIS P 8205, 1976). Quality spacer paper P. By using such a spacer paper P, even if particles (such as pulp or a small amount of resin component) are generated by the spacer paper P, the glass plate G can be placed in an upright position with respect to the base 3. The particles or the like are not fixed to the surface of the glass sheet G, and can be easily removed by washing or the like of the glass sheet G thereafter.

As shown in FIG. 1B, the spacer paper P is larger than the glass sheet G. Therefore, at least the upper end portion extends upward from the upper side of the glass sheet G when the glass sheet G is placed to form the extending portion PE. Further, in the present embodiment, the side of the left and right sides of the glass sheet G, that is, the side of the glass sheet G in the direction orthogonal to the direction of the arrow X in Fig. 1A, the spacer paper P is also extended (extended). (not shown). The extension portion PE extending above the glass sheet G has a length of, for example, about 50 to 80 mm. Further, the lengths of the portions projecting from the left and right sides are also substantially the same length as the extension portions PE.

Moreover, the lower end PL of the spacer paper P is lower than the bottom pallet 4 as shown in FIG. 2B. The upper surface (mounting surface) is suspended, for example, at about 5 mm. Thereby, when the glass sheet G and the spacer paper P are alternately arranged on the bottom pallet 4 from the side of the back panel 5, the lower end portion of the spacer paper P can be prevented from being spread on the bottom pallet 4 at intervals of spreading. The case where the glass plate G is placed on the paper P. If the glass sheet G is placed on the spacer paper P, the movement of the glass sheet G on the bottom pallet 4, that is, the sliding to the side of the backing plate 5 due to its own weight is limited, and also for the glass sheet G. Unloading has an impact.

Further, the extension portion PE of the spacer paper P is uniformly inclined toward the side of the back plate 5 as shown in FIG. 2A. By the same means, all the extension parts PE are inclined at substantially the same angle in the same direction (the side of the backing plate 5). Further, the term "substantially the same angle" means a deviation of, for example, about ±20% with respect to a specific angle, preferably about 10% or less. In the present embodiment, the extension portion PE is inclined at an angle substantially equal to the inclination angle θ of the back plate 5, i.e., the end surface 12 of the back plate 5. In this manner, by making the extending portion PE of the spacer paper P uniformly inclined, the spacer P can be removed from the glass sheet G by the arm using the extending portion PE as follows, and the extending portion PE can be favorably performed. The positioning of the robot arm.

Further, in the package body 2 of the present embodiment, as shown in FIG. 1B, after the glass sheet G and the spacer paper P are alternately arranged on the packaging container 1, various conventionally known fixtures (not shown) are used. The glass plate G is fixed, and if necessary, it is formed in a final form for transportation or the like by adhering a resin sheet or storing it in a packing box.

For example, the glass plate G is fixed in the packaging container 1 by using the glass plate pressing member 13 as shown by the two-dot chain line in Fig. 1B. Glass plate extrusion member 13 series The front frame 14 and the side frame 15 are provided, the side frames 15 are attached to both side portions of the support frame 8, and the front frame 14 is attached to the front end of the side frame 15. The glass sheet pressing member 13 is detachably attached to the front frame 14 by, for example, the front frame 14 or the side frame 15 is detachably attached to the support frame 8 to be pressed into the glass sheet pressing member 13. The accommodation of the glass plate G is possible.

Further, in the glass plate pressing member 13, the air bag 16 may be provided inside the front frame 14 (between the front frame 14 and the glass plate G). The glass sheet G is pressed against the back sheet 5 side by the airbag 16, whereby the glass sheet G can be surely fixed. As such an airbag 16, it is preferable to press and fix the glass plate G by adjusting the amount of air to expand it appropriately. The airbag 16 may be provided with one or two or more as needed.

Further, as the fixture for the glass sheet G, it is preferable to provide a side pressing member (not shown) for holding and fixing the side surface G1 of the glass sheet G shown in Fig. 1B.

Next, an embodiment of the method for forming the package body 2, that is, the method of packing the present invention will be described.

First, the glass plate G and the spacer paper P are alternately arranged on the bottom pallet 4 of the packaging container 1 shown in FIG. 1B, whereby a plurality of glass G plates are placed on the bottom pallet 4, and the spacer paper is sandwiched. Between the glass sheets G. The placement of the glass sheet G on the bottom pallet 4 is carried out in the same manner as before by a dedicated robot arm (not shown). Further, the arrangement of the spacer paper P on the glass sheet G is also performed in the same manner as before by a dedicated robot arm (not shown). At this time, as shown in FIG. 2B, the spacer paper P is disposed such that the lower end PL of the spacer paper P is suspended from the bottom pallet 4 by, for example, about 5 mm. Further, as shown by the two-dot chain line in Fig. 2A, the upper end portion is extended from the upper side of the glass sheet G by about 50 to 80 mm to form the extending portion PE.

If a specific number of glass sheets G are loaded on the bottom pallet 4, and the spacer paper P is sandwiched between the glass sheets G, respectively, the glass shown by the two-dot chain line in FIG. 1B is used. The glass plate G is fixed to the packaging container 1 by the plate pressing member 13 or the like.

Then, the extending portion PE of the spacer paper P sandwiched between the glass sheets G is inverted toward the side of the back sheet 5 and uniformly inclined. As a process of inclining the extending portion PE, for example, as shown in Fig. 3, the extending portion PE is inverted toward the upper end surface 12 side of the backing plate 5, and a plate-shaped pressing body (hammer) 17 is placed thereon. At this time, the pressing body 17 is disposed such that its bottom surface (pressing surface) is substantially parallel to the upper end surface 12 of the backing plate 5. Further, in this state, the specific time is maintained, for example, one night, after which the pressurizing body 17 is removed from the extension portion PE. As a result, the extension portion PE is erected to some extent, but remains in the reverse direction of being pressurized. Therefore, as shown in FIG. 2A, the extending portion PE is inclined at a substantially equal angle to the inclination angle θ of the upper end surface 12 of the backing plate 5 or at a larger angle.

In other words, all of the extending portions PE are pressurized for the same period of time under the same pressure, and thus are uniformly inclined toward the backing plate 5 side. The angle of the inclination is not particularly limited as long as it is inclined by less than 90° with respect to the front and back surfaces of the glass sheet G, for example, from 30°. That is, when the extension portion PE by the following robot arm is held by suction, the inclination angle with respect to the extension portion PE can be adjusted by the adjustment of the arm side, so that the arm angle is fixed as long as the inclination angle is fixed. The positioning of the extension PE can be performed well.

Here, in the present embodiment, the upper end surface 10a of the inclined frame 10 and the upper end surface 12 of the back plate 5 are arranged in the same plane, so that when the extending portion PE is reversed toward the back plate 5 side as shown in FIG. The spacer paper P disposed on the side of the back sheet 5 is also placed on the end surface 12 of the back sheet 5 such that the extension portion PE is not interfered by the tilt frame 10, for example. Therefore, the extension portion PE of the spacer paper P disposed on the side of the back sheet 5 can be reliably pressed by the pressurizing body 17 similarly to the other extension portions PE.

In this manner, the extending portion PE is uniformly inclined, and if necessary, the resin sheet is adhered to the glass sheet G or the like in the same manner as before, and is formed to be finally provided for transportation or the like.

Next, the attachment and detachment of the glass sheet G from the package body 2 thus formed will be described.

First, a resin sheet or the like or other fixture is removed from the bale container 1 in the same manner as before.

Then, the loading and unloading of the glass sheet G from the bottom pallet 4 and the removal of the spacer paper P from the glass sheet G are performed. The loading and unloading of the glass sheet G from the bottom pallet 4 is performed in the same manner as before by a dedicated robot arm (not shown). For example, the outer surface of the glass sheet G (the surface opposite to the back sheet 5) is suction-held by a hole for vacuum suction or a mechanical arm having a suction cup, and is transferred to a transfer device such as a conveyor.

Further, the removal of the spacer paper P from the glass sheet G is also performed in the same manner as before by a dedicated robot arm. For example, after loading and unloading the outermost glass sheet G, the paper P exposed to the outermost surface is adsorbed and held by the circular arm robot 18 of a specific length as shown in FIG. Machine and other transfer devices. The robot arm 18 has a plurality of adsorption holes 19 formed on one side of the side surface (peripheral surface), and a known person who vacuum-adsorbs and holds the spacer paper P through the adsorption holes 19 is provided.

To grasp and hold the spacer paper P by the robot arm 18, first, the robot arm 18 is advanced as indicated by an arrow A in FIG. At this time, the adsorption holes 19 are oriented in the traveling direction. Further, as soon as the robot arm 18 reaches above the extension portion PE of the spacer paper P to be held, the robot arm 18 is rotated in the direction of its axis rotation as indicated by the arrow B, and the adsorption hole 19 is oriented in a specific direction, for example, below. . Then, as shown by the arrow C, the mechanical arm 18 is lowered, and the adsorption hole 19 is brought into contact with the extension portion PE of the spacer paper P to start the adsorption of the adsorption hole 19. Thereby, the extension portion PE can be adsorbed and held by the adsorption holes 19.

When the extension portion PE is adsorbed and held as described above, since the extension portion PE of the spacer paper P is uniformly inclined, it is only necessary to repeat the same operation every time with respect to the operation of the robot arm 18. That is, in addition to the fact that the position of the extension portion PE gradually shifts toward the back plate 5 side, since the inclination of the extension portion PE is uniform, the orientation of the adsorption hole 19 can be fixed. Therefore, the positioning of the extension portion PE of the mechanical arm 18 can be easily and satisfactorily performed.

Further, when the extending portion PE is sucked and held by the mechanical arm 18, the mechanical arm 18 is raised in the opposite direction to the arrow C, and the mechanical arm 18 is moved to the belt conveyor (not shown) in which the spacer paper P is stacked. The direction is moved, and thereafter the adsorption of the adsorption holes 19 is stopped and the spacer paper P is dropped onto a belt conveyor or the like. By this series of operations, the spacer paper P can be removed from the glass sheet G.

According to the packaging container 1 of the present embodiment, the support surface 5a of the backing plate 5 is formed to have substantially the same height as the height of the glass plate G to be mounted, and the back is The upper end surface 12 of the plate 5 is formed as an inclined surface which becomes higher as the self-supporting surface 5a faces the back surface 5b located on the opposite side of the support surface 5a, so that the glass plate G is placed on the bottom pallet 4 and After the one side is supported by the backing plate 5, the extending portion PE can be reversed by the extending portion PE extending from the upper side of the glass sheet G of the spacer P between the glass sheets G to the backing plate 5 side. The inclined faces (upper end faces 12) along the backing plate 5 are uniformly inclined.

Moreover, by making the height of the backing plate 5 substantially the same as the height of the glass plate G to be mounted, as shown in FIG. 3, when the extending portion PE is pressurized by the pressing body 17, especially for the side of the backing plate 5 The extension portion PE can also support the lower side thereof by the back plate 5. Thereby, the extension portion PE is pressurized under substantially the same conditions as the other extension portions PE, so that it can be inverted toward the back plate 5 side.

Further, by making the inclination angle θ of the upper end surface 12 (inclined surface) of the back sheet 5 with respect to the thickness direction of the back sheet 5 to be more than 0° and not more than 20°, the extension portion PE of the spacer paper P can be inclined. It is better to stabilize its slope. In particular, as shown in FIG. 4, when the spacer P is held by the mechanical arm 18 and the spacer P is removed from the glass sheet G, even if the last remaining pieces are removed, At this time, the specific inclination can be maintained by the extending portion PE against the inclined surface (upper end surface 12) or the like, so that the extending portion PE can be more reliably adsorbed and held.

Further, according to the package 2 of the present embodiment, the extending portion PE of the spacer paper P which is mounted between the glass sheets G of the packaging container 1 is inclined obliquely along the inclined surface (upper end surface 12) of the back sheet, and thus The positioning by the extension portion PE of the robot arm 18 can be satisfactorily performed at the time of unloading, so that the spacer paper P can be stably adsorbed and held, and is reliably removed from the glass sheet G.

Further, according to the packing method of the present embodiment, the extending portion PE of the spacer paper P interposed between the glass sheets G of the packaging container 1 is uniformly inclined along the inclined surface (upper end surface) of the back sheet 5, and thus Since the positioning of the extension portion (holding portion) of the robot arm can be satisfactorily performed at the time of unloading, the spacer paper can be stably adsorbed and held, and can be reliably removed from the glass sheet G.

Further, when the spacer paper P is sandwiched between the glass sheets G, as shown in FIG. 2B, the spacer paper P is disposed such that the lower end PL thereof is suspended from the bottom pallet 4, so that the spacer is placed at the bottom. When the glass plate G and the spacer paper P are alternately arranged from the side of the back plate 5, the lower end portion of the spacer paper P is prevented from being spread on the bottom pallet 4, and the glass plate G is placed on the spread paper P. The situation.

Next, another embodiment of the packaging container of the present invention, the packaging body using the same, and the packaging method will be described using FIG. 5 which is a side sectional view of a main part of the package.

This embodiment differs from the embodiment shown in Fig. 2A in the height of the backing plate. That is, the height of the support surface 5a (the surface on the side of the glass plate G to be mounted) of the back sheet 5 shown in Fig. 2A is substantially the same as the height of the glass sheet G, whereas the present embodiment shown in Fig. 5 is used. The height of the support surface 20a (the surface on the side of the glass plate G to be mounted) of the back sheet 20 is lower than the height of the glass sheet G.

The height of the support surface 20a of the backing plate 20 with respect to the height of the glass sheet G is preferably about 1 mm to 5 mm lower than the glass sheet G. By making the support surface 20a slightly lower than the glass sheet G, the extending portion PE of the spacer P can be more reliably and stably maintained in a state of being inclined toward the backing plate 20 side. Therefore, as shown in FIG. 4, when the extension portion PE of the spacer paper P is sucked and held by the mechanical arm 18 and the spacer paper P is removed from the glass sheet G, the extension portion can be more reliably adsorbed and held. PE.

In other words, in the packaging container of the embodiment including the above-described configuration, the extending portion PE of the spacer paper P sandwiched between the glass sheets G can be inverted toward the backing plate 20 side, so that the extending portion PE is carried along the back. The inclined faces (upper end faces) of the plates 20 are uniformly inclined. Moreover, since the height of the supporting surface 20a of the backing plate 20 is slightly lower than the height of the glass plate G to be mounted, the extending portion PE of the spacer paper P can be more reliably and stably inclined toward the backing plate 20 side.

Further, according to the package body and the packing method of the present embodiment, in addition to the effects obtained in the previous embodiment, the following advantageous effects can be obtained: the support surface 20a of the backing plate 20 is slightly lower than Since the glass plate G can more reliably perform the adsorption holding of the extending portion PE of the spacer paper P of the robot arm 18, the spacer paper P can be more reliably removed from the glass sheet G.

The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit and scope of the invention.

For example, the configuration of the base 3 in the packaging container 1 and the configuration of the support frame 8 are not limited to those shown in FIGS. 1A and 1B, and various conventionally known configurations can be employed.

Although an embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. Various modifications and substitutions of the embodiments described above are possible without departing from the scope of the invention.
