Description

Glass plate package {GLASS PLATE PACKING BODY}

This invention relates to the improvement technique of the glass plate package in which the glass plate laminated body in which the several sheet glass plate was laminated | stacked was hold | maintained on the pallet.

As is well known, in transporting various glass plates such as glass substrates for flat panel displays (hereinafter referred to simply as FPDs), such as liquid crystal displays and plasma displays, glass plates in which a glass plate laminate formed by laminating a plurality of glass plates is held on a pallet. It is customary to carry out in the state of a package.

As this kind of glass plate package, it is divided into what hold | maintained the several glass plate laminated | stacked on the pallet in the vertical position, and hold | maintained the several glass plate laminated | stacked on the pallet in the horizontal position.

As a former package, the pallet provided with the base part and the backrest part standing up behind the base part is used. And after wrapping several sheets of glass plate on the backrest part, and laminating | stacking in a vertical position on a base part, the package is produced by pressing and holding the front surface of the glass plate laminated body toward the backrest part side.

At this time, there are various methods for pressing the glass laminate, but, for example, Patent Document 1 described below sets up the front frame separately in front of the base of the pallet and presses the linkage to the front frame through a link mechanism. Another method of pressing and holding a glass plate laminated body to the backrest part side by the piece is disclosed. In addition, when the posture of the front frame is changed, the pressing force by the pressing piece is lowered so that the upper bar is sandwiched between the upper surface of the front frame and the upper surface of the backrest portion so that the front frame is maintained in an upright state.

However, in such a configuration, it is necessary to combine the front frame or the upper bar into a watchtower shape in order to press the glass plate stack with the pressing piece, which not only complicates the configuration of the package but also compels cumbersome and cumbersome work in the production of the package. do. In particular, the front frame is required to be larger than the glass plate since the relationship is over the top bar. Therefore, when the glass plate used as a packing object is large, a front frame will also enlarge and handling property will worsen. In addition, in this case, since it is necessary to perform the mounting work of the upper bar at a high place, it becomes difficult to perform the mounting work smoothly.

Then, what copes with such a problem is what presses and hold | maintains a glass plate laminated body by the following structures. In other words, the push bar is disposed so as to span the width direction of the glass plate laminate laminated on the pallet, and the both ends of the push bar protruding to the outside of the width direction both sides of the glass plate laminate are fastened so as to be pulled into the pallet side by the fastening member. The sieve was pressed and held on a pallet (for example, following patent document 2).

In this way, it is not necessary to separately install the front frame or the upper bar on the pallet, and it is possible to easily hold the glass plate laminate on the pallet simply by fastening both ends of the push bar by the fastening member.

Patent Document 2: Japanese Patent Laid-Open No. 2006-347592

However, when the glass plate laminate is pressed against the pallet side and held by fastening both ends of the push bars arranged to span the width direction of the glass plate laminate, stress tends to be concentrated at both ends in the width direction of the glass plate. In addition, since bending occurs in the push bar itself, stress is more likely to be concentrated by both ends of the glass plate. Since the edge part of a glass plate is a site | part which is easy to cause damage, when a packing is carried out in the state which stress concentration generate | occur | produced in the edge part of a glass plate as mentioned above by the pressing force by a push bar, a problem arises that a glass plate is broken until unzipping.

Moreover, when the bending of a push bar is large, only the width direction both ends of a glass plate laminated body will be kept. When the package is transported in this state, a problem arises in that the center portion in the width direction of the glass sheet is deformed like the push bar by the vibration or the impact during the transportation and causes collapse. In the transport destination, it is usual for the glass plate to be taken out one by one from the pallet by a robot equipped with an adsorption pad, but as described above, if the collapse occurs and the glass plate is curved, the adsorption pad cannot adsorb the glass plate properly. The problem may arise that the take-out operation by the robot becomes practically impossible.

In addition, such a problem is not limited to the case where a plurality of glass plates are stacked and packed in a vertical posture, and the same problem may occur even when a plurality of glass plates are stacked and packed in a horizontal posture.

In view of the above circumstances, the present invention reduces the breakage of the glass plate due to stress concentration at both ends in the width direction while adopting a packing form in which the push bars are arranged so that the glass plate laminate spans the width direction, and both ends of the push bars are held in the pallet. The technical problem is to prevent the collapse of the glass laminate.

In order to solve the above problems, the present invention provides a push bar so as to span the width direction of the glass plate laminate laminated on the pallet, and both ends of the push bar protruding outward on both sides of the glass plate laminate. A glass plate package in which the glass plate laminate is pressed and held on the pallet by fastening so as to be pulled into the pallet side by a fastening member, wherein the pressing plate is interposed in a state in which both the push bars and the glass plate laminate are in contact with each other. In addition, the pressing plate is in contact with the width direction central portion except for the width direction both ends of the glass plate laminate.

According to such a structure, since a pressing plate is non-contact with the width direction both ends of a glass plate laminated body, the pressing force by a push bar does not act on the width direction both ends of a glass plate. Therefore, stress concentration hardly arises in the width direction both ends of a glass plate laminated body, and it becomes possible to reduce damage of a glass plate effectively.

Moreover, since the pressing plate contacts the width direction center part except the width direction both ends of a glass plate laminated body, the pressing force by a push bar acts on a center part. Therefore, the displacement of the center part of a glass plate laminated body is regulated. Therefore, even when the package is transported, the collapse of the glass plate laminate can be reliably suppressed.

In the said structure, it is preferable that the part which contacts the said push bar among the said press plates is continuous in the width direction of the said glass plate laminated body.

When it does in this way, the width direction center part excluding the width direction both ends of a glass plate laminated body is stretched in the width direction, and is pressed continuously. Therefore, the situation that a glass plate deform | transforms like a wave | undulation in the width direction like the case where the width direction center part of a glass plate laminated body is intermittently pressed in the width direction can be prevented. Therefore, breakage and collapse of the glass plate by deformation can be suppressed more reliably.

In the said structure, it is preferable that the said press plate has the dimension of the direction orthogonal to the width direction of the said glass plate laminated body larger than the said push bar.

In this way, since the dimension of the direction orthogonal to the width direction of the glass plate laminated body of a push bar is smaller than that of a pressure plate, the pressing force which acts on a glass plate laminated body more than the case where the glass plate laminated body is directly pressed by a push bar is used for the width direction. It can disperse | distribute in the wide range of the direction orthogonal to. Therefore, the deformation | transformation in the direction orthogonal to the width direction of a glass plate is suppressed, and it is advantageous in preventing damage or collapse of a glass plate.

In the above configuration, the glass plate laminate may be formed by stacking a plurality of glass plates in a vertical posture, and the pallet may have a base for supporting the lower side of the glass plate and a back support for supporting the rear part of the glass plate. In addition, in this case, the width direction of a glass plate laminated body means the direction orthogonal to the up-down direction (height direction) of a glass plate laminated body.

In the said structure, it is preferable that the lower end part of the said press board is spaced apart from the base part of the said pallet.

Generally, in the glass plate laminated body which laminated | stacked the several sheets of glass plate in the vertical position, the lower side part is supported by the base part of a pallet, and this lower side part becomes small in freedom of a deformation | transformation and a movement. Therefore, when the pressing plate is brought into contact with the lower side and the pressing force is applied by the push bar, stress concentration due to the pressing force cannot be alleviated by deformation of the glass plate or the like, so that the glass plate is easily broken. Therefore, it is also preferable from the viewpoint of preventing breakage of the glass plate that the lower end of the pressing plate is separated from the base portion such that the pressing force does not act on the lower side of the glass plate as in the above configuration.

In this case, an arm extending outwardly on both sides in the width direction of the glass plate laminate is provided on both sides in the width direction of the pressing plate, and extends in the lamination direction of the glass plate laminate on both sides in the width direction of the backrest portion of the pallet. A guide member for slidably supporting the arm may be provided, and the lower end of the pressing plate may be separated from the base of the pallet by supporting the arm with the guide member.

By doing so, by sliding the pressing plate along the guide member, the pressing plate can be easily positioned at an appropriate position according to the number of laminated sheets of the glass plate.

The said structure WHEREIN: A plurality of said push bars are arrange | positioned in the up-down direction of the said glass plate laminated body, and the pressing force per unit area which acts on the glass plate laminated body by an uppermost push bar acts on the said glass plate laminated body by the lowermost push bar. It is preferable to make it smaller than the pressing force per unit area.

Generally, in the glass plate laminated body which laminated | stacked the several sheets of glass plate in the vertical position, since the lower side part contact | connects the base part of a pallet, the upper side part is in the state which moves relatively freely in the state which is hard to move. Therefore, the laminated thickness of the upper part of a glass plate laminated body is easy to change than the laminated thickness of the lower part. Therefore, when the pressing force equal to the upper part and the lower part of a glass plate laminated body is made to apply, the lamination thickness of an upper part becomes thinner than the lamination thickness of a lower part, and a lamination | stacking state becomes easy to be uneven. And when the nonuniformity of such a laminated state arises, the upper part of a glass plate laminated body is hold | maintained in the pressed state rather than a lower part. Therefore, when the impact which pushes up from the bottom to a package during transportation is added, there is no room for a glass plate to move upwards, and the impact may act directly on the lower side part of a glass plate, and may be broken. Therefore, in order to cope with such a problem, it is preferable to make the pressing force per unit area acting on the glass plate laminate by the uppermost push bar as the above structure smaller than the pressing force per unit area acting on the glass plate laminate by the lowermost press bars. By doing in this way, the situation that the upper part of a glass plate laminated body is maintained in the pressed state compared with the lower part can be reduced, and the situation that the laminated state of a glass plate laminated body becomes nonuniform can be prevented. In addition, since the pressed state of the upper part and the lower part of a glass plate laminated body can be maintained to the same grade, even when the impact which pushes upwards at the time of transport is applied, a glass plate is temporarily avoided upward and it becomes difficult to damage a glass plate.

In the above configuration, the pressing plate is at least separated into an upper pressing plate for pressing the glass plate laminate by the uppermost push bar and a lower pressing plate for pressing the glass plate laminate by the lower pressing bar, It is preferable that the contact area with the glass plate laminated body of a press plate is larger than the contact area with the glass plate laminated body of the said lower press plate.

In this case, since the contact area with the glass plate laminated body of an upper press plate becomes larger than the contact area with the glass plate laminated body of a lower press plate, the pressing force acting on a glass plate laminated body by an upper press plate is laminated by a glass plate by a lower press plate. It is dispersed and weakened in a wider range than the pressing force acting on the sieve. Therefore, the pressing force per unit area which acts on a glass plate laminated body by the uppermost push bar can be made smaller than the pressing force per unit area which acts on a glass plate laminated body by a lowermost press bar.

In the above configuration, the pressure plate is a single member disposed between the uppermost push bar and the lowermost push bar, and the protruding dimension of the upper part of the upper part of the upper pushbar is higher than the lower part of the lower part. It is preferable that it is larger than the protrusion dimension below a press bar. In addition, the protruding dimension of the lower part of the lower part of a press board below the press bar also includes the case where the lower part of a press plate does not protrude below a press bar, ie, the value becomes zero.

By doing so, the pressing force acting on the glass plate laminate by the uppermost push bar is more widely dispersed than the pressing force acting on the glass plate laminate by the lowermost press bars. Therefore, the pressing force per unit area which acts on a glass plate laminated body by the uppermost push bar can be made smaller than the pressing force per unit area which acts on a glass plate laminated body by a lowermost press bar.

In the above configuration, the glass plate laminate may be formed by stacking a plurality of glass plates in a horizontal posture, and the pallet may have a base that supports the lower surface portion of the glass plate. In addition, in this case, the width direction of a glass plate laminated body means the direction orthogonal to the front-back direction of a glass plate laminated body.

In the above configuration, the pallet is provided with a reference wall in contact with one side positioned behind the glass plate, and a plurality of the push bars are arranged in the front-rear direction of the glass plate laminate, and the glass plate is laminated by the push bar at the rearmost part. It is preferable to make the pressing force per unit area acting on a sieve smaller than the pressing force per unit area acting on the said glass plate laminated body by the push bar of the foremost part.

In general, when the reference wall is formed on the pallet in contact with one side located behind the glass plate, the one side located behind the glass plate before and after transportation is in contact with the reference wall from the viewpoint of preventing the collapse of the glass plate. It is required to be in a state. And, according to the above configuration, such a request can be satisfied. In other words, when an impact is applied to the package during transportation, each glass plate is guided to the rear side with a small pressing force per unit area, so that one side positioned behind the glass plate is brought into contact with the reference wall.

In the above configuration, the pressing plate is at least separated into a front pressing plate for pressing the glass plate laminate by the push bar of the frontmost portion and a rear pressing plate for pressing the glass plate laminate by the pressing bars of the rearmost portion. It is preferable that the contact area with the said glass plate laminated body of the said back part press plate is larger than the contact area with the said glass plate laminated body of the said front part press plate.

In this way, since the contact area with the glass plate laminated body of a rear side press plate becomes larger than the contact area with the glass plate laminated body of a front side press plate, the pressing force acting on a glass plate laminated body by a rear side press plate is a front part pressure plate. This is dispersed and weakened in a wider range than the pressing force acting on the glass plate laminate. Therefore, the pressing force per unit area which acts on a glass plate laminated body by a push bar of a rearmost part can be made smaller than the pressing force per unit area which acts on a glass plate laminated body by a push bar of a front part.

In the above configuration, the pressing plate is a single member disposed between the push bar of the foremost part and the push bar of the rear part, and the protruding dimension of the rear part of the rear part of the push bar is the frontmost portion of the front part of the front part. It is preferred that the negative push bar is larger than the protruding dimension forward. In addition, the protruding dimension of the front part of the pressing plate toward the front of the push bar of the foremost part also includes the case where the front part of the pressing plate does not protrude forward of the pressing bar of the foremost part, that is, the value becomes zero.

In this way, the pressing force acting on the glass plate laminated body by the push bar of the rearmost part is disperse | distributed more extensively than the pressing force acting on the glass plate laminated body by the push bar of the frontmost part. Therefore, the pressing force per unit area which acts on a glass plate laminated body by a push bar of a rearmost part can be made smaller than the pressing force per unit area which acts on a glass plate laminated body by a push bar of a front part.

In the said structure, it is preferable that the said glass plate laminated body arrange | positions a buffer plate on the surface of the side pressed by the said press member.

Effect of the Invention

As described above, according to the present invention, the pressing plate is not in contact with the width direction both ends of the glass plate laminate, and thus the pressing force by the push bar does not act on the width direction both ends of the glass plate. Therefore, stress concentration hardly arises in the width direction both ends of a glass plate laminated body, and breakage can be reduced effectively to a glass plate. On the other hand, since the pressing plate is in contact with the center portion in the width direction except for the both ends in the width direction of the glass plate laminate, the pressing force by the push bar is concentrated on the width direction center portion of the glass plate laminate. Therefore, as a result of the restriction | limiting of the displacement of the width direction center part of a glass plate laminated body, the situation that a collapse occurs in a glass plate laminated body can be suppressed reliably.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described based on drawing.

1 is a perspective view schematically showing a glass plate package according to a first embodiment of the present invention, and FIG. 2 is a plan view thereof. As shown in each of these drawings, the glass plate package 1 laminates a plurality of glass plates on the pallet 2 in a vertical position, and holds the glass plate laminate G on the pallet 2. .

The pallet 2 is provided with the base part 2a which supports the lower side part of a glass plate, and the back part 2b which stands up behind the base part 2a, and supports the back surface of a glass plate. And the several glass plate is laminated | stacked on the pallet 2 by the vertical attitude | position by mounting each lower side part of several sheets of glass plate to the base part 2a, and hanging the back part of the rearmost glass plate on the backrest part 2b. Moreover, the foamed resin sheet is interposed between each glass plate in the glass plate laminated body G, and the buffer board 3 formed with the plastic corrugated board etc. hangs on the front part of the glass plate of the head, for example. In addition, although not shown in the figure, the shock absorbing material is attached to the part which the glass plate laminated body G contacts with the pallet 2.

And two push bars 4 are arrange | positioned at the outermost surface (buffer plate 3) of glass plate laminated body G in the up-down direction so that it may span the width direction. In this state, the both ends of each push bar 4 which protruded to the outer side of the width direction both sides of the glass plate laminated body G are fastened so that it may pull in to the backrest part 2b side by the fastening member 5.

Although the structure of the fastening member 5 is not specifically limited, In this embodiment, as shown in FIG. 3, of the rack 5a and the push bar 4 extended in the glass plate lamination direction from both sides of the backrest part 2b. The pinion 5b built in both ends is provided with the main structure. The push bar 4 is fixed to the rack 5a by engaging the pinion 5b with the rack 5a. In addition, the push bar 4 is slidably supported with respect to the rack 5a in the state which has engaged the pinion 5b and the rack 5a. The pinion 5b is also connected to the first crankshaft 5c. The first crankshaft 5c is biased in the left direction in the drawing by the spring 5e mounted on the second crankshaft 5d whose movement is restricted in the state where the pinion 5b and the rack 5a are engaged. biasing). Accordingly, the pinion 5b is biased by the spring 5e in the direction (counterclockwise direction in the drawing) in which the pinion 5b is engaged with the pinion 5b in a state where the pinion 5b is engaged with the rack 5a.

A press plate 6 is interposed between the press bar 4 and the glass plate laminate G as shown in FIGS. 1 and 2. This pressing plate 6 is in contact with both the push bar 4 and the glass plate laminated body G, and the contact area is continuous in the width direction center part except the width direction both ends of the glass plate laminated body G. As shown in FIG. That is, the width direction center part of the push bar 4 is in the state which protruded toward the glass plate laminated body G side by the press plate 6. Therefore, the clearance gap corresponding to the thickness of the press plate 6 is formed between the push bar 4 and the width direction both ends of the glass plate laminated body G, and the pressing force by the push bar 4 laminated | stacks a glass plate. It does not act on the width direction both ends of the sieve G. On the other hand, since the pressing plate 6 is in continuous contact with the width direction center part of the glass plate laminated body G in the width direction, the pressing force by the push bar 4 concentrates on the width direction center part of the glass plate laminated body G. It is supposed to.

Thereby, it becomes possible to hold | maintain glass plate laminated body G on the pallet 2, without focusing stress in the width direction both ends of glass plate laminated body G. As shown in FIG. Therefore, the situation where a stress concentrates in the width direction both ends of glass plate laminated body G, and a glass plate is damaged can be reduced effectively. In addition, since the pressing force by the push bar 4 acts continuously on the width direction center part of the glass plate laminated body G via the press plate 6, deformation, such as curvature in the width direction center part of the glass plate laminated body G, is carried out. Is regulated. Therefore, the situation that the glass plate laminated body G falls by the vibration at the time of transport etc. can be reduced effectively.

Moreover, it is preferable that the thickness of the press plate 6 is 5 mm or more and 40 mm or less, and it is more preferable that they are 10 mm or more and 30 mm or less. In addition, the width direction dimension of the press plate 6 is at least 1/3 of the width direction dimension of the glass plate laminated body G, and the width direction both ends of the press plate 6 are the width direction of the glass plate laminated body G at the maximum. It is preferable to set in the range located 50 mm inside from both ends, and it is more preferable that they are 1/2 or more and 2/3 or less of the width direction dimension of glass plate laminated body G. The pressure plate 6 may be separate from the push bar 4, but is integrated with the push bar 4 in the present embodiment.

4 is a perspective view showing a glass plate package according to a second embodiment of the present invention, and FIG. 5 is a side view thereof. As shown in each of these figures, the upper part of the two push bars 4 which are different from the glass plate package 1 which concerns on the 1st embodiment mentioned above differs from the glass plate package 1 which concerns on this 1st Embodiment. The pressing force per unit area acting on the glass plate laminate G by the push bar 4 is lower than the pressing force per unit area acting on the glass plate laminate G by the lower push bar 4. .

Generally, in the glass plate laminated body G which laminated | stacked the several glass plate in the vertical position, since the lower side contact | connects the base part 2a of the pallet 2, the upper edge part moves relatively freely in the state which is difficult to move. Is in. Therefore, the laminated thickness of the upper part of glass plate laminated body G tends to change than the laminated thickness of the lower part. Therefore, when the equal force is applied to the upper part and the lower part of the glass plate laminated body G, the lamination thickness of an upper part becomes thinner than the lamination thickness of a lower part, and a lamination | stacking state tends to become nonuniform. And when the nonuniformity of such lamination | stacking state arises, the upper part of glass plate laminated body G is hold | maintained in the pressed state rather than a lower part. Therefore, when the impact which pushes up the glass plate package 1 from the bottom during transportation is applied, there is no room for a glass plate to move upwards, and the impact may act directly on the lower side part of a glass plate, and may be damaged.

Therefore, in order to cope with such a problem, the pressing force per unit area acting on the glass plate laminated body G by the upper push bar 4 among the upper and lower push bars 4 is lowered by the lower push bar 4 by the glass plate. It is preferable to make it smaller than the pressing force per unit area which acts on laminated body G. By doing in this way, the situation that the upper part of glass plate laminated body G is kept pressed compared with the lower part can be reduced, and the situation that the laminated state of glass plate laminated body G becomes nonuniform can be prevented. In addition, since the pressing state of the upper part and the lower part of the glass plate laminated body G can be maintained to an equal degree, even if the impact which pushes up from the bottom to the package 1 during transport is carried out, glass plate temporarily avoids upwards and it damages a glass plate. This becomes difficult to occur.

In detail, in this embodiment, as shown to FIG. 4 and FIG. 5, the contact area of the glass plate laminated body G of the pressing plate 6 which presses the glass plate laminated body G by the upper push bar 4 is shown. It is larger than the contact area of the glass plate laminated body G of the press plate 6 which presses the glass plate laminated body G by this downward press bar 4. Therefore, the pressing force which acts on the glass plate laminated body G by the upper press bar 4 is disperse | distributed extensively compared with the pressing force which acts on the glass plate laminated body G by the lower press bar 4. As a result, the pressing force per unit area acting on the glass plate laminate G by the upper push bar 4 is smaller than the pressing force per unit area acting on the glass plate laminate G by the lower press bar 4. It becomes possible to exhibit the above-mentioned effect.

In addition, as shown in FIG. 2, the push bar 4 lower than the push bar 4 of the upper side of the push bar 4 by the force of the spring 5e which biases the pinion 5b in the direction which engages with the rack 5a. By strengthening at, the pressure bar per unit area acting on the glass plate laminate G by the pressing bars 4 may be formed such that the difference as described above.

It is a perspective view which shows the glass plate package which concerns on 3rd Embodiment of this invention. As shown in the same figure, the glass plate package 1 which concerns on this 3rd Embodiment differs from the glass plate package 1 which concerns on 1st-2nd embodiment mentioned above to the upper and lower two push bars 4. The single pressing plate 6 is pressed against each other.

In detail, the press plate 6 is comprised from the continuous flat plate without the clearance, and is arrange | positioned so that it may be extended from the upper push bar 4 to the lower push bar 4. This pressing plate 6 is smaller than the glass plate, and is in non-contact with the edge portion of the glass plate. In this way, the pressing force by the push bar 4 acts not only in the width direction of the glass plate laminated body G, but also in the up-down direction orthogonal to the width direction. Therefore, a glass plate will be in the state which is hard to produce a deformation | transformation more, and it is advantageous in suppressing breakage and collapse.

In addition, from the viewpoint of weight reduction, the pressing plate 6 may be configured as a lattice plate as shown in Figs. 7 (a) and 7 (b). In this case, as shown to Fig.7 (a), the grid | lattice body 6a is arrange | positioned in the width direction in the place where the push bar 4 is arrange | positioned among the press plates 6, and the press force by the push bar 4 It is made to act continuously in the width direction of glass plate laminated body G.

In addition, as described in the second embodiment, the pressing force per unit area acting on the glass plate laminate G by the upper pressing bar 4 among the two upper and lower pressing bars 4 is the lower pressing bar 4. It is preferable to carry out as follows from a viewpoint of making it smaller than the pressing force per unit area which acts on glass plate laminated body G by this. That is, as shown to FIG. 6 and FIG. 7 (a), the press board 6 is made to bias the up-down center position of the press board 6 to the upper direction rather than the up-down center position between the two upper and lower push bars 4, and FIG. It is preferable that the upper part of the upper side of the pressure plate 6 has a larger projecting dimension from the upper push bar 4 to the upper side than the lower part of the pressing plate 6 from the lower pressing bar 4.

In this case, the pressure applied to the glass plate laminate G by the upper push bar 4 is more widely dispersed and weaker than the pressing force acting on the glass plate laminate G by the lower push bar 4. do. Therefore, the pressing force per unit area acting on the glass plate laminated body G by the upper push bar 4 is smaller than the pressing force per unit area acting on the glass plate laminated body G by the lower push bar 4. can do.

FIG.8 (a), (b) is a perspective view which shows the glass plate package which concerns on 4th Embodiment of this invention. As shown in the same figure, it is the width direction both sides of the press plate 6 that the glass plate package 1 which concerns on this 4th Embodiment differs from the glass plate package 1 which concerns on 1st-3rd embodiment mentioned above. The pressure plate 6 is supported in the state separated from the base 2a of the pallet 2 by engaging the arm 7 extending to the outside of the pallet 2 by the rack 5a provided on the pallet 2.

As the belt 5, a ratcheting lashing belt can be suitably used.

In addition, as shown in FIG. 13, you may fasten so that both ends of the press bar 4 may be drawn in to the backrest part 2b side between the both ends of the push bar 4, and the back part 2b. .

In addition, as shown in FIG. 14, the both ends of the push bar 4 are fastened by fastening the belt 5 from the both ends of the push bar 4 to the back surface of the back support part 2 from the back side of the back part 2b. You may make it pull in to the backrest part 2b side.

It is a perspective view which shows the glass plate package which concerns on 6th Embodiment of this invention, and FIG. 16 is its top view. As shown in each of these drawings, the glass plate package 1 according to the sixth embodiment differs from the glass plate package 1 according to the first to fifth embodiments described above in plural glass plate laminates G. It exists in the point which laminated | stacked the sheet | seat glass plate on the base part 2a of the pallet 2 in the horizontal position, and comprised it.

That is, the matter demonstrated in the above-mentioned 1st-5th embodiment can be applied similarly to the case where the multiple sheets of glass plate are laminated | stacked and packed. In this case, however, it is necessary to take into account the lateral shift of the glass plate due to the vibration or shaking during transportation. Therefore, when packing the glass plate laminated body G laminated | stacked in the horizontal attitude | position, as shown to FIG. 15 and FIG. 16, the reference wall 2c which contacts the one side located in the back of the glass plate laminated | stacked in the horizontal attitude | position is made. It may be installed in the pallet 2. And in this case, it is necessary also to make it the state which the one side of the back side of the glass plate contacted the reference wall 2c before and after transportation from the viewpoint of preventing the collapse of the glass plate laminated body G.

Therefore, in the glass plate package 1 which concerns on this embodiment, the pressing force per unit area which acts on the glass plate laminated body by the push bar 4 of the back among the two push bars 4 arrange | positioned with the clearance in the front-back direction is The front push bar 4 becomes smaller than the pressing force per unit area acting on the glass plate laminated body G. As shown in FIG. Specifically, the contact area of the glass plate laminated body G of the pressing plate 6 which presses the glass plate laminated body G by the back push bar 4 is made into the glass plate laminated body by the front push bar 4 ( It becomes larger than the contact area of the glass plate laminated body G of the press plate 6 which presses G).

In this way, even when an impact is applied to the glass plate package 1 at the time of transport, each glass plate is guide | induced to the back side where the pressing force per unit area is small. Therefore, it becomes possible to transport in the state which the one side located in the back of a glass plate contacted the reference wall 2c.

In addition, as shown in FIG. 17 and FIG. 18, when pressing the single press plate 6 with the front and back two push bars 4, the front-back direction center position of the press plate 6 is set as the front and back two push bars ( 4) The rear portion of the pressing plate 6 projects rearward from the rear pressing bar 4 by biasing the rear side of the front-back direction center position therebetween, so that the front portion of the pressing plate 6 is the front pressing bar 4 You may make it larger than the dimension which protrudes from the front. And when the press plate 6 is comprised by the grating board like the example of illustration, the lattice body 6a is arrange | positioned in the place where the push bar 4 is arrange | positioned, and the pressing force by the push bar 4 is a glass plate laminated body ( It is made to act continuously in the width direction of G).

In this case, since the pressing force acting on the glass plate laminated body G by the back push bar 4 is disperse | distributed more extensively than the pressing force acting on the glass plate laminated body G by the front push bar 4, The pressing force per unit area acting on the glass plate laminate by the push bar 4 can be made smaller than the pressing force per unit area acting on the glass plate laminate G by the front push bar 4.

In addition, as shown in FIG. 2, the push bar 4 in front of the push bar 4 behind the push bar 4 receives the force of the spring 5e for biasing the pinion 5b in the direction in which the pinion 5b engages with the rack 5a. By strengthening at, the pressure bar per unit area acting on the glass plate laminate G by the front and rear push bars 4 may be formed to have the above-described difference.

EXAMPLE

In order to recognize whether the present invention achieves the desired object, the following test and its investigation were conducted.

As Example 1 of the form which packs a glass plate in the vertical position of this invention, 50 glass plate package 1 of the form shown in the above-mentioned FIG. 1 and FIG. 2 was produced, and about 100 km of one way highways were carried out. It reciprocated at km / h, and the change of the lamination | stacking thickness of the glass plate before and behind the damage situation of the glass plate after transportation was confirmed. Moreover, the glass substrate for liquid crystal displays whose width direction dimension is 2250 mm, the up-down direction dimension is 1950 mm, and thickness is 0.7 mm was used as a glass plate. And 200 glass sheets were laminated | stacked in the vertical posture, and each glass plate package 1 was produced. As the push bar 4, stainless steel angled pipes having a width direction of 2538 mm, an up and down direction of 80 mm, and a thickness of 40 mm were used. Further, as the pressing plate 6, a stainless steel angled pipe having a width direction of 1500 mm, an up and down direction of 80 mm, and a thickness of 20 mm is used, and the pressure plate 6 is pushed to the push bar 4. Joined and integrated.

As a result, the number of pieces of damage after transportation of 10000 sheets (50 x 200 pieces) of glass sheets became 0 sheets, and very good results were obtained. In addition, the maximum free fall change amount of the laminated thickness of the glass plate was 6 mm on average, and was 9 mm maximum free fall (fall 2 mm before transport + free fall change 7 mm after transport). Therefore, the maximum free fall means the lamination thickness difference (difference between the largest thickness dimension and the smallest thickness dimension) from the foremost part to the rear part in the lamination direction of one glass plate laminate G, and generally the glass plate collapses. If the maximum drop of the lamination thickness exceeds 15 mm, the glass plate cannot be automatically taken out of the pallet 2 by the robot having the suction pad. Therefore, the result that the maximum drop is 9 mm is satisfactory in practical use.

As Example 2 of this invention, 50 glass plate package 1 of the form shown in FIG. 4 and FIG. 5 mentioned above was produced. A stainless steel angled pipe having a width direction of 1500 mm, an up and down direction of 80 mm, and a thickness of 20 mm was joined to the lower press bar 4. In addition, the upper push bar 4 was joined with a stainless steel angled pipe having a width direction of 2150 mm, an up and down direction of 160 mm, and a thickness of 20 mm as the pressing plate 6. In addition, other conditions are the same as that of the said Example 1.

As a result, the number of pieces of damage after transportation of 10000 sheets (50 x 200 pieces) of glass sheets became 0 sheets, and very good results were obtained. In addition, the maximum free fall change amount of the laminated thickness of the glass plate was 4 mm on average, and was a maximum free fall 7 mm (fall 2 mm before transport + drop 5 mm after transport). Therefore, while the maximum free fall became 15 mm or less, which is an allowable range, the result was better than that in Example 1.

As Example 3 of this invention, 50 glass plate packages 1 of the form shown to FIG. 8 (a) mentioned above were produced. The pressing plate 6 is combined in a grid shape with an angled pipe having a cross section of 40 mm x 20 mm as a skeleton, and the thickness is 20 mm and the width direction dimension is 1500 mm, which is 2/3 of the width direction dimension of the glass plate. Furthermore, the upper part protruded 350 mm from the upper push bar 4. In addition, in the frame of the press plate 6, the grid | lattice body 6a of 80 mm of the up-down direction same as the press bar 4 is arrange | positioned in the location where the press bar 4 is arrange | positioned, and the press bar 4 and the press bar 4 are pressed. The board 6 was made to contact continuously in the width direction. In addition, other conditions are the same as that of Example 1 mentioned above.

As a result, the number of pieces of damage after transportation of 10000 sheets (50 x 200 pieces) of glass sheets became 0 sheets, and very good results were obtained. In addition, the maximum free fall change amount of the laminated thickness of the glass plate was 2 mm on average, and was 5 mm maximum free fall 2 mm before transport + free fall change amount 3 mm after transport. Therefore, while the maximum free fall became 15 mm or less, which was an allowable range, the result was better than that in Example 2.

As Example 4 of this invention, 50 glass plate package 1 of the form shown to FIG. 10 (a) mentioned above was produced. As the press plate 6, the same thing as Example 3 mentioned above was used, and the leg part 8 was attached instead of the arm 7. As shown in FIG. In addition, other conditions are the same as that of Example 1.

As a result, the number of pieces of damage after transportation of 10000 sheets (50 x 200 pieces) of glass sheets became 0 sheets, and very good results were obtained. In addition, the maximum free fall change amount of the laminated thickness of the glass plate after transportation was 2 mm on average, and was 6 mm maximum free fall (fall 2 mm before transport + free fall change 4 mm after transport). Therefore, while the maximum free fall became 15 mm or less, which was an allowable range, the result was better than that in Example 2.

As Comparative Example 1 of Examples 1 to 4, in Example 1, 50 glass laminates were prepared in which the pressing plate 6 was removed and the glass laminate was pressed directly by the push bar 4. In addition, other conditions are the same as that of Example 1.

As a result, four pieces of the broken pieces after transportation of the glass plate of 10000 sheets (50 x 200 pieces) were generated. Two pieces were broken from the lower edge part of the glass plate as a detail, and two pieces were broken from the both ends of the width direction of the glass plate as a starting point. On the other hand, the maximum free fall change amount of the laminated thickness of the glass plate after transportation was an average of 17 mm, and was a maximum free fall 20 mm (fall 2 mm before transportation + drop 18 mm after transportation). Therefore, the maximum fall exceeded 15 mm which is an allowable range.

As Example 5 of the aspect which wraps a glass plate in the horizontal posture of this invention, 50 glass plate package 1 of the form shown in FIG. 17 and FIG. 18 mentioned above was produced. Each glass plate package 1 laminated | stacked 200 glass sheets similar to the above, and produced it. As the pressing plate 6, the same thing as Example 3, 4 was used, and the rear part was made to protrude 350 mm from the back push bar 4 to the reference wall 2c side. In addition, other conditions are the same as that of Example 1.

As a result, the number of pieces of damage after transportation of 10000 sheets (50 x 200 pieces) of glass sheets became 0 sheets, and very good results were obtained. In addition, the maximum free fall change amount of the laminated thickness of the glass plate after transport was 2 mm on average, and was 4 mm maximum free fall (fall 2 mm before transport + free fall change 2 mm after transport). Therefore, the good result was a maximum fall of 15 mm or less which is an allowable range.

As Comparative Example 2 of Example 5, in Example 5, 50 glass plates were prepared in which the pressing plate 6 was removed and the glass plate laminate G was pressed directly by the push bar 4. In addition, other conditions are the same as that of Example 5.

As a result, the number of pieces of damage after transportation of 10000 pieces (50 x 200 pieces) of glass plates became two pieces. In detail, the two glass plates which were broken were both damaged from the width direction both ends of a glass plate. On the other hand, the maximum free fall change amount of the laminated thickness of the glass plate after transportation was an average of 13 mm, and was a maximum free fall 16 mm (fall 2 mm before transportation + drop 14 mm after transportation). Regarding the lateral shift of the glass plate, the whole glass plate after transportation moved in the direction of about 20 mm away from the reference wall 2c. Therefore, about the maximum fall, the horizontal deviation and breakage of the glass plate exceeded 15 mm which is an allowable range also resulted in the result.
