Description

Laminate tray integrated piece and tray

Technical Field

The utility model relates to a laminate tray integrated member and a tray.

Background

In recent years, as glass substrates for flat panel displays have been increased in size and reduced in thickness, glass substrates are sometimes stacked in a vertical orientation when being packed. As a tray for packing glass substrates in a state of being stacked in a vertical posture, there is known a tray including: a bottom side support portion that supports a bottom side of a laminate in which a plurality of glass substrates are laminated in a vertical posture; a back support portion that supports a back surface of the laminated body; and a cushion plate disposed between the rear support portion and the laminated body (see, for example, patent document 1). In the present specification, the vertical posture includes a vertical posture in which the surface of the glass substrate is parallel to the vertical plane and an inclined posture in which the surface of the glass substrate is inclined with respect to the vertical plane.

Such a laminate is mainly made by performing the following: after the glass substrates are delivered from the glass manufacturer to, for example, a panel manufacturer in a packed state on the tray having the above-described configuration, the glass substrates are taken out from the tray by an unpacking device called an unpacking device. In this case, as the unpacking device, there is an unpacking device including an adsorption pad for vacuum-adsorbing the glass substrates and an adsorption pad for vacuum-adsorbing the interleaving paper interposed between the glass substrates (see patent document 2).

SUMMERY OF THE UTILITY MODEL

Problem to be solved by utility model

When the glass substrate is taken out from the tray using the unpacking device provided with the suction pad as in patent document 2, an operation of moving the interleaving paper from the glass substrate and discharging the interleaving paper is required. In this case, the operation of discharging the interleaving paper can be roughly divided into an operation of holding the portion of the interleaving paper protruding from the glass substrate by suction with the suction pad, and an operation of retracting the held interleaving paper from the tray. As described in patent document 2, for example, when the backing paper is supposed to fall toward the back surface side when the suction pad is pressed in, the suction pad is moved obliquely upward from a direction perpendicular to the stacking direction of the glass substrates. However, in this method, when the remaining amount of the interleaving paper and the glass substrate is small, the distance between the interleaving paper and the back surface support portion (or the buffer plate) becomes short, and therefore the pouring angle of the interleaving paper when the suction pad is pressed in becomes smaller than before. In this case, the pressing angle of the suction pad and the pouring angle of the interleaving paper are deviated, and the suction pad and the interleaving paper are partially in contact with each other, so that it is difficult to stably suck and hold the interleaving paper.

Further, when the remaining amount of the interleaving paper and the glass substrate becomes small, the suction pad is moved obliquely upward along the back surface supporting portion of the tray in a state where the interleaving paper is strongly pressed against the back surface supporting portion by the suction pad, and therefore, if the interleaving paper held by the suction pad is retreated from the tray, the interleaving paper may be detached from the suction pad and fall due to an increase in frictional resistance acting on the back surface supporting portion and the interleaving paper.

In view of the above, an object of the present invention is to stably suck and hold a protective sheet even when the remaining amount of the protective sheet is small when the protective sheet such as a mount is discharged from a laminate on a tray.

Means for solving the problems

The above object is achieved by the integrated laminate tray of the present invention. That is, the integrated member is a laminated body tray integrated member including a laminated body in which a plurality of glass plates and protective plates are alternately laminated, and a tray capable of holding the laminated body in a vertical posture, and is characterized in that the tray includes a back surface portion which forms a support surface for supporting the back surface side of the laminated body in the vertical posture, the support surface includes a first opposing region facing the glass plates and a second opposing region facing a portion of the protective plate protruding from the glass plates, and a variable surface capable of being pressed is provided in the second opposing region.

As described above, in the integrated laminate tray of the present invention, the region (second opposing region) facing the protective sheet protruding from the glass plate, of the supporting surface that supports the back surface of the laminate in a state in which the glass plate and the protective sheet are alternately laminated in the vertical posture, is provided with the press-fitting changeable surface. According to the above configuration, when the remaining amount of the protective sheet and the glass plate is small, the protective sheet and the changing surface are collectively pressed by the suction pad, and therefore the protective sheet can be tilted by a necessary and sufficient amount. Therefore, the contact state between the protective sheet and the suction pad can be stabilized, and the protective sheet can be reliably sucked and held. Further, since the changing surface is pressed together with the protective sheet, the frictional resistance acting on the protective sheet can be reduced, and the protective sheet can be prevented from falling off the suction pad.

In the integrated laminate tray of the present invention, the variable surface may be deformed in accordance with press fitting.

By forming the changing surface of an elastic body such as rubber or sponge in this manner and deforming in response to press fitting, the protective sheet can be reliably caused to fall by a sufficient amount necessary for the press fitting of the suction pad, and the frictional resistance acting on the protective sheet can be reliably reduced.

In the integrated laminate tray of the present invention, the changing surface may move in accordance with the press-fitting.

By configuring the changing surface to move in accordance with the press-fitting in this manner, the protective sheet can be reliably tilted by a sufficient amount required for the press-fitting of the suction pad, and the frictional resistance acting on the protective sheet can be reliably reduced.

In the integrated laminate tray of the present invention, the changing surface may be formed of a plate-like member, and the plate-like member may be configured to be tiltable about an axis parallel to the support surface.

In this way, if the changing surface is formed by the plate-like member, the shape of the protective sheet when pressed in is stabilized. For example, by forming the surface of the plate-like member in a flat shape, the shape of the protective sheet when pressed in is stabilized in a substantially flat shape. Therefore, the protective sheet can be stably held by suction through the suction pad or the like. In addition, according to the above configuration, the changing surface can be provided in the second opposing region relatively easily. Therefore, the improvement of the tray can be completed with a minimum necessary, and the technical problem can be solved at low cost.

In the integrated laminate tray of the present invention, the plate-like member may be biased in a direction against the press-fitting.

By configuring the plate-like member as described above, the plate-like member can be automatically returned to the position or posture before press-fitting with the press-fitting release. In addition, since a very simple structure is sufficient if only the plate-like member is urged, the cost for improving the tray is also suppressed.

In the laminate tray of the present invention, the variable surface may be formed of a metal.

By forming the modified surface with metal in this way, the frictional resistance can be reduced as compared with a case where the modified surface is formed with rubber or sponge, and the durability of the modified surface is also excellent. Therefore, the tray having the variable surface can be used for a long period of time.

In the integrated laminate tray of the present invention, the changing surface may be located above the first opposing region.

By providing the changing surface above the first opposing area, the changing surface effectively functions when, for example, the protective sheet is lifted from a state of being sucked and held and discharged to the outside of the tray. That is, since the working space is easily secured above the periphery of the tray, the bundling work can be efficiently performed in terms of the working space by providing the changing surface above the first opposing area, and the protective sheet can be smoothly discharged at this time.

In the integrated laminate tray of the present invention, the variable surface may be rectangular and divided in the longitudinal direction.

While the position (position in the pressed state) where the protective sheet is sucked and held by the suction pad or the like is set to a predetermined position, the position and size of the stacked body mounted on the tray are slightly different for each product. Therefore, when the suction pads arranged along the longitudinal direction (for example, the horizontal direction) of the rectangular changing surface are pressed toward the protective sheet at the same position, the pressing amount may be different in the longitudinal direction. In contrast, by dividing the variable surface in the longitudinal direction as in the present embodiment, even when the variable surface is formed of a plate-like member, for example, the degree of press-fitting of the variable surface (in this case, the degree of tilt of the plate-like member) is made different for each plate-like member in the longitudinal direction, and thus variations in the press-fitting amount in the longitudinal direction can be absorbed.

The above object is also achieved by the pallet of the present invention. That is, the tray is a tray capable of holding a stacked body in a vertical posture in a state in which a plurality of glass plates and protective sheets are alternately stacked, and is characterized by comprising a rear surface portion which forms a support surface for supporting the rear surface side of the stacked body in the vertical posture, the support surface having a first opposing region which faces the glass plates and a second opposing region which faces a portion of the protective sheet which protrudes from the glass plates, and a press-fitting changeable surface being provided in the second opposing region.

As described above, in the tray of the present invention, the press-fitting changeable surface is provided in the region (second opposing region) facing the protective sheet protruding from the glass plate, among the supporting surfaces supporting the rear surface of the laminated body in a state in which the glass plate and the protective sheet are alternately laminated in the vertical posture. Therefore, according to the above configuration, as in the case of the integrated member of the present invention, when the remaining amount of the protective sheet and the glass plate is small, the protective sheet and the changing surface are collectively pressed by the suction pad, and therefore the protective sheet can be tilted by a necessary and sufficient amount. Therefore, the contact state between the protective sheet and the suction pad can be stabilized, and the protective sheet can be reliably sucked and held. Further, since the changing surface is pressed together with the protective sheet, the frictional resistance acting on the protective sheet can be reduced, and the protective sheet can be prevented from falling off the suction pad.

Effect of the utility model

As described above, according to the laminate tray integrated piece and the tray of the present invention, when the protective sheet such as the interleaving paper is discharged from the laminate on the tray, the interleaving paper can be stably sucked and held even when the remaining amount of the interleaving paper is small.

Detailed Description

< first embodiment of the present invention >

Hereinafter, a first embodiment of the present invention will be described with reference to fig. 1 to 8. In all the following embodiments, a case will be described as an example in which a glass plate to be laminated is a glass substrate for a flat panel display, and a laminate in which the glass substrates are laminated with interleaving paper interposed therebetween is mounted on a tray.

Fig. 1 shows a perspective view of a laminate tray integrated piece 1 of a first embodiment of the present invention. Fig. 2 is a side view of the laminate tray integrated member 1, and fig. 3 is a view of the laminate tray integrated member 1 as viewed from the direction of arrow a shown in fig. 2. As shown in fig. 1 to 3, the laminate tray integrated unit 1 includes a tray 2 and a laminate 3 mounted on the tray 2.

Here, the laminate 3 is formed by alternately laminating a plurality of glass sheets G and interleaving papers I in a vertical posture (in the present embodiment, an inclined posture). In the present embodiment, the glass sheets G and the interleaving paper I are both rectangular, and the interleaving paper I is disposed on the most back surface side of the laminate 3.

Here, an example of the specification of the laminate 3 will be described, in which the size of the glass plate G is 730mm × 920mm to 2250mm × 2600mm, and the thickness of the glass plate G is 300 μm to 1100 μm. The interleaving paper I constituting the laminate 3 together with the glass sheets G is, for example, a plain paper pulp. The size (area) of the interleaving paper I is generally larger than that of the glass sheets G, and the interleaving paper I and the glass sheets G are alternately arranged so that the glass sheets G do not directly contact each other. This makes up the laminated body 3 in which the glass sheets G and the interleaving papers I are alternately laminated.

The tray 2 mainly includes a base portion 4 located on the bottom side 3a side of the stacked body 3 and a back surface portion 5 located on the back surface 3b side of the stacked body 3. In the present embodiment, the base portion 4 includes a bottom edge support portion 6 that supports the bottom edge 3a of the stacked body 3, and a receiving plate 7 that is disposed between the bottom edge support portion 6 and the stacked body 3. The rear surface portion 5 includes a rear surface support portion 8 standing upright from the base portion 4 and supporting the rear surface 3b of the stacked body 3, and a cushion plate 9 disposed between the rear surface support portion 8 and the stacked body 3. The receiving plate 7 and the buffer plate 9 may be one or a plurality of plates. In the present embodiment, one receiving plate 7 and one buffer plate 9 are disposed on the bottom support portion 6 and the back support portion 8, respectively.

As shown in fig. 2, the upper surface 6a of the bottom support portion 6 is inclined at a predetermined angle θ 1 (for example, 5 ° to 25 °) with respect to the horizontal direction in a direction moving upward as it moves away from the back surface portion 5. As also shown in fig. 2, the front surface 8a of the rear surface support portion 8 is inclined at a predetermined angle θ 2 (for example, 5 ° to 25 °) with respect to the vertical direction in a direction moving rearward as it moves away from the bottom surface support portion 6. At this time, the front surface 8a of the rear surface support portion 8 is, for example, substantially perpendicular to the upper surface 6a of the bottom side support portion 6. The angle formed by the upper surface 7a of the receiving plate 7 with respect to the horizontal direction is the same as the angle θ 1 formed by the upper surface 6a of the bottom side supporting portion 6 with respect to the horizontal direction, and the angle formed by at least the region of the front surface 9a of the buffer plate 9 facing the glass sheet G with respect to the vertical direction is the same as the angle θ 2 formed by the front surface 8a of the back side supporting portion 8 with respect to the vertical direction.

The receiving plate 7 as the bottom side buffer plate and the back side buffer plate 9 may be formed of a material having both appropriate cushioning properties and mechanical strength, such as a foamed resin. For example, the receiving plate 7 and the buffer plate 9 are formed by using foamed polypropylene, foamed polyethylene, polyurethane (including foamed polyurethane and non-foamed polyurethane), foamed styrene, and foamed melamine as main materials.

As shown in fig. 3, the width-directional dimension of the cushion plate 9 is smaller than the width-directional dimension of the front surface 8a of the rear support portion 8, and the upper portion and both side portions of the front surface 8a are in a state of protruding from the cushion plate 9. Here, the width direction of the buffer plate 9 is the same as the width direction of the glass sheets G stacked on the tray 2 in the vertical posture, and is the longitudinal direction of the side of the glass sheets G extending in the horizontal direction. At this time, the area of the stacked body 3 is smaller than the area of the front surface 9a of the buffer plate 9, and both side portions of the buffer plate 9 protrude from the stacked body 3 in a state where the stacked body 3 is placed on the tray 2 as shown in fig. 1. As shown in fig. 4, the upper portion of the buffer plate 9 protrudes from the glass plate G, and the interleaving paper I protrudes from the upper portion of the buffer plate 9. Therefore, at least the entire surface of the glass plate G is supported by the front surface 9a of the buffer plate 9 through the mount paper I.

In addition, when the sizes of the glass plates G and the interleaving papers I are compared, the area of the glass plates G is smaller than that of the interleaving papers I, and in a state where the glass plates G and the interleaving papers I are alternately stacked in the vertical posture, the interleaving papers I are protruded from the glass plates G at the upper side of the glass plates G as enlarged in fig. 4. In this case, the plate-like member 10 is disposed adjacent to the upper end of the buffer plate 9, and the front surface 10a of the plate-like member 10 faces the portion of the interleaving paper I protruding from the upper edge of the glass plate G. In the present embodiment, although not shown, the interleaving paper I is extended from the glass plate G on both side edges of the glass plate G, and the front surface 9a of the buffer plate 9 is extended from the interleaving paper I on both side edges. As described above, in the present embodiment, the front surface 9a of the cushion plate 9 and the front surface 10a of the plate-like member 10 correspond to the support surface of the present invention. Further, a region of the front surface 9a of the buffer plate 9 facing the entire surface of the glass plate G corresponds to the first facing region 11a of the present invention, a region of the front surface 9a facing the interleaving paper I protruding from the side edge of the glass plate G and a region of the front surface 10a of the plate-like member 10 facing the interleaving paper I protruding from the upper edge of the glass plate G correspond to the second facing region 11b of the present invention.

The second opposing region 11b is provided with a press-fitting changeable surface 12 (see fig. 4). In the present embodiment, a rectangular changing surface 12 is provided in a portion of the second opposing region 11b that faces the mount I protruding from the glass plate G on the upper side of the glass plate G. In this case, the changing surface 12 is formed by the front surface 10a of the movable plate-like member 10, and the plate-like member 10 is biased toward the pressing direction against the predetermined direction by being coupled to the rear surface support portion 8 via the biasing member 13, for example. In the present embodiment, the upper end of the plate-like member 10 is coupled to the rear surface support portion 8 via the biasing member 13, whereby the plate-like member 10 can tilt about an axis whose upper end extends in the horizontal direction. Further, the inclination angle θ 3 of the changing surface 12 with respect to the first opposed region 11a changes in accordance with the pressing of the mount I. As the biasing member 13, for example, a spring such as a compression coil, a torsion coil spring, or a thin plate spring, or a rubber plate can be used, and any element having any material and structure can be used as long as it can bias the pressing direction against the interleaving paper I. In the present embodiment, the plate-shaped member 10 and the back surface support portion 8 are coupled to each other so as to be tiltable by the biasing member 13 and the plate-shaped member 10 is biased, but the plate-shaped member 10 may be biased by a biasing member such as a compression coil in a state where the plate-shaped member 10 and the back surface support portion 8 are coupled to each other so as to be tiltable by a coupling member such as a hinge.

In a state (a state shown in fig. 4) where no load (press-fitting force or the like) is applied (a state shown in fig. 4) to the front surface 10a (the changing surface 12) of the plate-like member 10, the front surface 10a is inclined with respect to the front surface 9a of the buffer plate 9 so as to recede to a lower side (lower left side in fig. 4) than the first opposing region 11a in the stacking direction X of the glass sheets G as it is separated from the first opposing region 11 a. The inclination angle θ 3 of the front surface 10a with respect to the first opposing region 11a is set within an appropriate range with respect to a press-in direction Y (see fig. 6A) of the suction pad 14 as a holding means to be described later, and is set to a predetermined magnitude such that, for example, the normal direction of the front surface 10a substantially coincides with the press-in direction Y.

The width-directional dimension of the front surface 10a (the changing surface 12) is set so that, for example, the mount I protruding on the upper side of the glass sheet G faces the entire width-directional region of the front surface 10a (see fig. 1 and 3). The dimension of the front surface 10a in the direction perpendicular to the width direction (vertical direction in fig. 3) is set such that, for example, the mount I protruding on the upper side of the glass sheet G faces the entire region of the front surface 10a in the vertical direction.

The plate-like member 10 is made of any material, and for example, a metal such as stainless steel can be used. In this case, the modified surface 12 formed by the front surface 10a of the plate-like member 10 is also formed of the same metal. Alternatively, the plate-like member 10 may be formed of a material other than metal, and the modified surface 12 may be made of metal by forming a metal film or the like on the surface thereof. Of course, the plate-like member 10 and the changing surface 12 may be formed of different metals.

The laminate tray integrated piece 1 having the above-described structure is packed in a predetermined form and shipped, for example. Fig. 5 shows an example of a package 15 in which the stacked bodies 3 of the stacked body tray integrated piece 1 of fig. 1 are packaged. As shown in fig. 5, the package 15 includes the above-described laminate tray integrated member 1, a tape 16 for binding the laminate 3, a pressing member 17 disposed between the tape 16 and the front surface of the laminate 3, and a side stopper 18 disposed between the tape 16 and the side of the laminate 3. For example, as shown in fig. 1, in a state where the stacked body 3 is mounted at a predetermined position on the tray 2 in the vertical posture, both ends in the longitudinal direction of the belt 16 are engaged with the hook portions 19 provided on the rear surface support portion 8, and are fixed in a state of being doubled up and fastened by a ratchet or the like, not shown, on the front surface of the pressing member 17. Thereby, the stacked body 3 is fixed to the tray 2 in a state of being restricted from moving in the front-rear left-right direction. In this case, as shown in fig. 5, the frame plate 20 may be placed on the foremost surface side of the laminated body 3, and the frame plate 20, the laminated body 3, and the pressing member 17 may be pressed toward the back support portion 8 by the belt 16.

At the shipment destination, the bundling unit 15 is opened to take out the glass sheets G from the laminate 3 on the tray 2. Hereinafter, the discharge step of the interleaving paper I when the glass sheets G are taken out and the operational effects of the present invention will be described mainly with reference to fig. 6A to 8.

The bale opening operation is performed by a bale opening device called an unpacking device, for example. Here, the unpacking device includes a first suction pad (not shown) for vacuum-sucking the glass sheets G and a second suction pad (suction pad 14 shown in fig. 6A) for vacuum-sucking the interleaving paper I interposed between the glass sheets G, the glass sheets G on the laminate 3 are suction-held by the first suction pad, the glass sheets G are taken out from the tray 2, the interleaving paper I is suction-held by the second suction pad (suction pad 14), and the interleaving paper is discharged to the outside of the tray 2.

Here, the operation of discharging the interleaving paper I is roughly divided into an operation of sucking and holding a portion of the interleaving paper I protruding from the glass plate G by the suction pad 14 and an operation of retracting the sucked and held interleaving paper I from the tray 2. Specifically, as shown in fig. 6A, for example, when the interleaving paper I is supposed to fall toward the rear surface support portion 8 when the suction pad 14 is pushed in, the suction pad is moved obliquely upward from the direction perpendicular to the stacking direction X of the glass sheets G. In this way, the suction pad 14 is pushed in from the predetermined direction Y toward the portion of the interleaving paper I located on the foremost surface side of the laminate 3, which portion protrudes from the glass plate G. Next, the interleaving paper I is vacuum-sucked in a state where the suction pad 14 is in close contact with the interleaving paper I, and the upper edge portion of the interleaving paper I is held by the suction pad 14.

Then, the suction pad 14 is moved in the planar direction of the glass plate G while maintaining the state in which the suction pad 14 is pressed into the interleaving paper I, thereby retracting the interleaving paper I from the stacked body 3. In the present embodiment, as shown in fig. 6B, the suction pad 14 is moved upward while maintaining a state in which the suction pad 14 is pressed into the interleaving paper I by rotating the suction pad 14 about a predetermined axis extending, for example, in the horizontal direction. This releases the close contact with the glass plate G positioned on the back side of the interleaving paper I, and only the interleaving paper I is discharged upward. The above operations and the operation of taking out the glass sheets G by the first suction pad (not shown) are alternately repeated, and the glass sheets G and the interleaving papers I are alternately discharged from the tray 2.

However, when the suction pad 14 is operated to discharge the interleaving paper I from the tray 2 as described above, if the remaining amount of the interleaving paper I and the glass sheets G is reduced, the contact state between the suction pad 14 and the interleaving paper I is changed, and therefore, it is difficult to stably suction and hold the interleaving paper I in the tray having the conventional configuration. That is, when the suction pad 14 is always pressed toward the interleaving paper I at a constant angle (pressing direction Y), as shown in fig. 8, in the tray 102 of the conventional configuration in which the changing surface 12 is not provided in the second opposing area 11b, when the interleaving paper I is pressed by the suction pad 14 in a state in which the remaining amount of the interleaving paper I is small, the inclination of the interleaving paper I to the back surface side is restricted by the second opposing area 11b (the front surface 9a of the buffer plate 9). As a result, the pouring angle of the interleaving paper I when the suction pad 14 is pressed in is smaller than when the remaining number of interleaving papers I is sufficient (fig. 6A) (see fig. 8). In this case, since the pressing angle of the suction pad 14 and the pouring angle of the interleaving paper I vary, and the suction pad 14 partially contacts the interleaving paper I, it is difficult to stably suck and hold the interleaving paper I.

In contrast, in the laminate tray integrated member 1 of the present invention, as shown in fig. 4 and the like, the press-fitting changeable surface 12 is provided in the second facing region 11b facing the interleaving paper I protruding from the glass plate G, of the supporting surface (here, the front surface 9a of the buffer plate 9 and the front surface 10a of the plate-like member 10) that supports the back surface 3b of the laminate 3. According to the above configuration, since the mount sheet I and the changing surface 12 are collectively pressed by the suction pad 14, the mount sheet I can be tilted by a sufficient amount (see fig. 7). As described above, according to the integrated laminate tray 1 of the present invention, the contact state of the interleaving paper I with the suction pad 14 can be stabilized regardless of the remaining number of interleaving papers I, and the interleaving paper I can be reliably sucked and held.

In the integrated laminate tray 1 of the present invention, the change surface 12 can support the interleaving paper I while absorbing the pressing force applied to the interleaving paper I toward the back surface side. Therefore, when the interleaving paper I is moved in the direction along the surface of the glass sheet G (the direction orthogonal to the stacking direction X) while being pushed in to the back surface side by the suction pad 14, the frictional resistance acting on the interleaving paper I can be reduced. As described above, according to the laminate tray integrated piece 1 of the present invention, it is possible to avoid the slip sheets I from falling off the suction pads 14, and it is possible to reliably discharge only the slip sheets I from the tray 2.

In the present embodiment, the changing surface 12 is formed on the front surface 10a of the movable plate-like member 10, and the plate-like member 10 is configured to be tiltable around an axis parallel to the first opposing region 11a serving as the support surface of the glass sheet G. When the varied surface 12 is formed by the front surface 10a of the plate-like member 10 in this manner, the shape of the interleaving paper I at the time of press-fitting is stabilized in a state of following the shape of the plate-like member 10. Therefore, the interleaving paper I can be stably sucked and held by the suction pad 14. Further, according to the above configuration, the interleaving paper I can be tilted to an appropriate posture (tilt angle) in response to the press-fitting of the suction pad 14. This stabilizes the contact state between the suction pad 14 and the interleaving paper I, and thus the interleaving paper I can be more reliably sucked and held and discharged while reducing the frictional resistance.

In the present embodiment, since the plate-like member 10 is biased in the direction against the press-fitting, the plate-like member 10 can be automatically returned to the position or posture before the press-fitting (for example, returned from the posture shown in fig. 7 to the posture shown in fig. 4) as the press-fitting of the interleaving paper I to the back surface side is released. Therefore, even when the pushing-in form of the interleaving paper I is changed due to the difference in the remaining number of interleaving papers I, the frictional resistance acting on the interleaving paper I can be stably reduced. Further, since a very simple structure is sufficient if only the plate-like member 10 is urged, the cost for improving the tray can be suppressed.

In the present embodiment, the front surface 10a (the changing surface 12) of the plate-like member 10 is inclined with respect to the front surface 9a of the buffer plate 9 so as to recede to a side (lower left side in fig. 4) lower than the first opposing region 11a in the stacking direction X of the glass sheets G as it moves away from the first opposing region 11a in a state (the state shown in fig. 4) where no arbitrary load (pressing force or the like) is applied. As a result, the interleaving paper I is easily toppled over when the suction pad 14 is pressed in, and therefore, the contact state between the interleaving paper I and the suction pad 14 can be further stabilized regardless of the remaining number of interleaving papers I, and the interleaving paper I can be more reliably sucked and held. In the case where the front surface 10a (changed surface 12) of the plate-like member 10 is inclined with respect to the front surface 9a of the cushion plate 9 in this manner, the inclination angle θ 3 of the front surface 10a (changed surface 12) of the plate-like member 10 is preferably set so that the normal direction of the front surface 10a substantially coincides with the press-fitting direction Y. In this case, it is preferable to thicken the cushion plate 9 to such an extent that the inclination of the front surface 10a of the plate-like member 10 can be secured.

The above description has been made of the laminate tray integrated piece and the first embodiment of the tray of the present invention, but it is needless to say that any form can be adopted for the laminate tray integrated piece and the tray within the scope of the present invention.

< second embodiment of the present invention >

For example, in the first embodiment, the case where the movable plate-like member 10 is provided adjacent to the upper end of the cushion plate 9 and the changed surface 12 is formed by the front surface 10a of the plate-like member 10 has been described with respect to the changed surface 12, but other embodiments are naturally possible. Fig. 9A and 9B are enlarged side views of the main part of a laminate tray integrated piece 21 according to a second embodiment of the present invention. As shown in fig. 9A, in the laminate tray integrated piece 21 of the present embodiment, a recessed portion 22 recessed from the front surface 8a is provided in the second facing region 11b facing the mount sheet I in the front surface 8a of the back surface support portion 8, and the plate-like member 10 is attached to the recessed portion 22. In this case, the front surface 10a of the movable plate-like member 10 forms the changed surface 23, and the upper end of the plate-like member 10 is connected to the inner surface of the recessed portion 22 via the biasing member 13, whereby the plate-like member 10 can be tilted in the recessed portion 22. According to the above configuration, for example, as compared with the case where the tiltable plate-like member 10 is provided on the front surface 8a of the rear surface support portion 8 (see fig. 4), a space for allowing the tilting of the plate-like member 10 can be provided on the rear surface side of the plate-like member 10 to be large (see fig. 9B). Accordingly, the allowable range of the press-in angle and the press-in amount of the suction pad 14 can be enlarged, and therefore, only the interleaving paper I can be more reliably discharged from the tray 2 by absorbing the press-in force and reducing the frictional resistance while stably sucking and holding the interleaving paper I. In fig. 9A, the lower end of the front surface 10a of the plate-like member 10 is set to be slightly lower than the front surface 9A (first opposing region 11a) of the cushion plate 9, but may be set to be higher conversely. Alternatively, the lower end of the front surface 10a of the plate-like member 10 may be at the same height as the front surface 9a of the buffer plate 9.

In the present embodiment, the front surface 10a (the changing surface 23) of the plate-like member 10 is parallel to the front surface 9A of the cushion plate 9 in a state (the state shown in fig. 9A) where an arbitrary load (a pressing force or the like) is not applied. In the present embodiment, the plate-like member 10 can be tilted about the upper end as a fulcrum. Therefore, when the remaining amount of the interleaving paper I and the glass sheet G is decreased, the pressing direction Y of the suction pad 14 (the normal direction of the suction surface) is deviated from the normal direction of the front surface 10a when the suction pad 14 is pressed, but the angle of the suction pad 14 is changed and the normal direction of the suction surface of the suction pad 14 coincides with the normal direction of the front surface 10a when the suction pad 14 is rotated around a predetermined axis extending in the horizontal direction. This makes it possible to reliably suction and hold the interleaving paper I regardless of the remaining number of interleaving papers I.

When the recessed portion 22 is provided in the rear surface support portion 8 as in the present embodiment, the rear surface support portion 8 is preferably formed in a box shape having an internal cavity. This ensures the rigidity of the rear surface support portion 8 without providing a beam, and thus facilitates the provision of the recessed portion 22.

< third embodiment of the present invention >

In the first and second embodiments of the present invention described above, the case where the plate-like member 10 is tilted with the upper end of the plate-like member 10 as a fulcrum is exemplified, but it is needless to say that other embodiments may be adopted. Fig. 10A and 10B are enlarged side views of a main part of a laminate tray integrated piece 31 according to a third embodiment of the present invention. As shown in fig. 10A, the plate-like member 10 of the present embodiment is attached to the recessed portion 22 provided on the front surface 8a of the rear surface support portion 8, as in the second embodiment. On the other hand, the plate-like member 10 is connected at its lower end to the inner surface of the recess 22 via the urging member 13. Thus, since the plate-like member 10 can tilt about the lower end thereof as a fulcrum, the changing surface 32 formed by the front surface 10a of the plate-like member 10 can also tilt about the lower end thereof as a fulcrum (see fig. 10B). With this configuration, a large space for allowing the plate-like member 10 to tilt can be provided on the back surface side of the plate-like member 10. Accordingly, the allowable range of the press-in angle and the press-in amount of the suction pad 14 can be enlarged, and therefore, while stably sucking and holding the interleaving paper I, the frictional resistance can be reduced by absorbing the press-in force, and only the interleaving paper I can be more reliably discharged from the tray 2.

In the present embodiment, the front surface 10A (the changed surface 32) of the plate-like member 10 is parallel to the front surface 9a of the cushion plate 9 in a state (the state shown in fig. 10A) where an arbitrary load (a pressing force or the like) is not applied. The plate-like member 10 of the present embodiment can tilt about the lower end (end on the side close to the first opposing region 11a) of the plate-like member 10 as a fulcrum. Therefore, when the remaining amount of the interleaving paper I and the glass sheet G is reduced, the front surface 10a is tilted in a process of collectively pressing the interleaving paper I and the changing surface 32 by the suction pad 14 or in a process of rotating the suction pad 14 about a predetermined axis extending in the horizontal direction, and the normal direction of the suction surface of the suction pad 14 coincides with the normal direction of the front surface 10 a. This makes it possible to reliably suction and hold the interleaving paper I regardless of the remaining number of interleaving papers I.

< fourth embodiment of the present invention >

In the above embodiment, the case where the plate-like member 10 is tiltable and the changing surfaces 12, 23, and 32 formed by the front surface 10a of the plate-like member 10 are moved (tilted) has been exemplified, but it is needless to say that other forms may be adopted. Fig. 11A and 11B are enlarged side views of a main part of a laminate tray integrated member 41 according to a fourth embodiment of the present invention. As shown in fig. 11A, in the laminate tray integrated member 41 of the present embodiment, the elastic plate 42 is disposed adjacent to the upper end of the buffer plate 9, and the front surface 43 of the elastic plate 42 forms the changing surface 4. In this case, the front surface 9a of the cushion plate 9 and the front surface 43 of the elastic plate 42 correspond to the bearing surfaces of the present invention. The elastic plate 42 is formed of, for example, a material that is more easily deformable than the cushion plate 9, specifically, an elastic body (rubber, sponge, or the like) whose front surface 43 can be deformed in accordance with the press-fitting of the suction pad 14. According to the above configuration, the pressing in of the interleaving paper I during the suction can be more flexibly handled. Therefore, even when the pressing-in form by the suction pad 14 is unstable, the frictional resistance can be reliably reduced.

< fifth embodiment of the present invention >

Fig. 12 is a perspective view of a laminate tray integrated piece 51 according to a fifth embodiment of the present invention. In fig. 12, the laminate 3 is indicated by a two-dot chain line. The laminate tray integrated member 51 of the present embodiment differs from the laminate tray integrated members 1, 21, 31, and 41 of the above embodiments in that the variable surfaces 52a to 52c, which are rectangular as a whole, are divided in the longitudinal direction thereof. Specifically, the front surfaces 53a1 to 53c1 of the plurality of plate-like members 53a to 53c divided in the horizontal direction and independently movable (tiltable in the present embodiment) form the changing surfaces 52a to 52c, respectively. According to the above configuration, even when the amount of pushing in the mount paper I by the suction pad 14 (see fig. 6A and the like) varies in the horizontal direction, the variation in the amount of pushing in the horizontal direction can be absorbed by making the degree of inclination of the plate-shaped members 53a to 53c different for each of the plate-shaped members 53a to 53 c. Therefore, according to the present configuration, it is possible to absorb the variation in the pushing amount in the horizontal direction and effectively reduce the frictional resistance acting on the interleaving paper I over the entire horizontal area. In fig. 12, the case where the changing surface is divided into three in the horizontal direction is exemplified, but it is needless to say that the changing surface may be divided into two or four or more in the horizontal direction depending on the application.

Of course, the forms of the modified surfaces 12, 23, 32, 44, 52a to 52c are arbitrary, and as long as press-fitting is possible, forms other than the above-described exemplary forms may be adopted. For example, although not described in detail, the plate-like member 10 shown in fig. 4 may be configured to approach the back support portion 8 so as not to change the inclination angle θ 3 in accordance with press-fitting, in other words, to move parallel to the stacking direction X so that the inclination angle θ 3 is constant.

In the above description, the case where the modified surfaces 12, 23, 32, 44, 52a to 52c are provided in the second opposed region 11b in the region opposed to the base sheet I protruding from the upper side of the glass sheet G has been exemplified, but it goes without saying that the modified surfaces 12, 23, 32, 44, 52 may be provided at other positions. For example, although not shown, when the interleaving paper I protruding from the side edge of the glass sheet G is sucked and held, and the interleaving paper I is moved in the horizontal direction and discharged from the tray 2, the changing surfaces 12, 23, 32, 44, 52a to 52c may be provided in the second facing region 11b in the region facing the interleaving paper I protruding from the side edge of the glass sheet G.

In the above description, the case where the interleaving paper I is used as the protective sheet when the glass sheets G are laminated was described, but it is needless to say that the interleaving paper I is not necessarily limited thereto. For example, paper other than the mount paper may be used as the protective sheet. Alternatively, a sheet made of a material other than paper (e.g., resin) may be used as the protective sheet. When the glass sheets G are stacked on the tray 2 or when the glass sheets G are taken out from the tray 2, the glass sheets G can be protected (the glass sheets G are prevented from being damaged), and sheets of any material and form can be used.

In the above description, the case where the integrated laminate tray 1 is packed, transported to a shipping destination or the like in a state of the package body 15, and unbundled (the glass sheets G are taken out) at the transportation destination has been exemplified, but the integrated laminate tray 1, 21, 31, 41, 51 of the present invention can be applied to other applications than the above. That is, the form may be arbitrary as long as the glass sheets G are mounted on the tray 2 in a state of being stacked in the vertical posture when the glass sheets G are taken out, and the tray 2 is not necessarily in the form premised on the package. For example, although not shown in the drawings, the present invention is also applicable to a tray configured to bring the glass sheets G (the stacked body 3) into a state of being stacked in a horizontal posture during conveyance and to bring the glass sheets G into a state of being stacked in a vertical posture during removal of the glass sheets G.
