Description

  The present invention relates to a laminated pallet integrated product and a pallet.

  2. Description of the Related Art In recent years, as glass substrates for flat panel displays have become larger and thinner, packing of the glass substrates may be performed in a state where the glass substrates are stacked in a vertical posture. In addition, as a pallet for packing glass substrates stacked in a vertical position, a bottom support portion that supports a bottom of a stacked body formed by stacking a plurality of glass substrates in a vertical position, and supports a back surface of the stacked body. There is a known device including a back support portion to be provided and a buffer plate disposed between the back support portion and the laminate (for example, see Patent Document 1). In this 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.

  In addition, this type of laminate is delivered from a glass maker to, for example, a panel maker in a state of being packed on the pallet having the above configuration, and then the unpacking device called an unpacker device removes the glass substrate from the pallet. The take-out method has become mainstream. At this time, as an unpacker device, there is an unpacker device having a suction pad for vacuum-sucking a glass substrate and a suction pad for vacuum-sucking an interleaf paper interposed between the glass substrates (both are patented). Reference 2).

  When taking out a glass substrate from a pallet using an unpacker device provided with a suction pad as in Patent Document 2, it is necessary to move the slip sheet from above the glass substrate and discharge it. At this time, the operation of discharging the slip sheet can be roughly classified into an operation of sucking and holding a portion of the slip sheet protruding from the glass substrate with a suction pad and an operation of retracting the held slip sheet from the pallet. . Among these operations, as for the operation of sucking and holding the slip sheet, as described in Patent Document 2, for example, assuming that the slip sheet falls down on the back side when the suction pad is pushed in, the stacking direction of the glass substrates is assumed. An operation of approaching the suction pad from obliquely above than the direction perpendicular to the vertical direction may be adopted. However, in this method, when the slip sheet and the glass substrate are reduced, the distance between the slip sheet and the back support portion (or the buffer plate) becomes shorter, so that the slip sheet falls down when the suction pad is pushed in. The angle becomes smaller. In this case, a difference occurs between the pressing angle of the suction pad and the falling angle of the slip sheet, and the suction pad partially contacts the slip sheet, so that the slip sheet can be stably held by suction. difficult.

  In addition, when the interleaf paper and the glass substrate are low, the suction pad is moved obliquely upward along the back support of the pallet in a state where the interleaf is strongly pressed against the back support by the suction pad. When the interleaf held by the pad is retracted from the pallet, the interleaf may fall off the suction pad due to an increase in frictional resistance acting on the back support and the interleaf.

  In view of the above circumstances, it is possible to solve the problem that when protecting sheets such as slip sheets are discharged from a laminate on a pallet, the protective sheets can be stably sucked and held even when the number of remaining protective sheets decreases. Should be technical issues.

  Solution to the above technical problem is achieved by a laminated pallet integrated product according to the present invention. That is, the integrated product is a laminated pallet integrated product including a laminated body in which a plurality of glass plates and protective sheets are alternately laminated, and a pallet capable of holding the laminated body in a vertical position. The pallet has a back surface portion that forms a support surface that supports the back side of the stacked body in the vertical position, and the support surface is eroded from the glass plate of the protective sheet and a first facing area facing the glass plate. It is characterized in that it has a protruding portion and a second opposing region opposing it, and the second opposing region is provided with a changeable surface that can be pushed.

  As described above, in the laminated body pallet integrated product according to the present invention, the glass plate and the protection sheet protrude from the glass plate among the support surfaces that support the back surface of the laminated body in a state where the glass plate and the protective sheet are alternately laminated in the vertical position. An indentable change surface was provided in an area (second opposing area) facing the protective sheet. According to the above configuration, when the protective sheet and the glass plate become small, the change surface is pushed together with the protective sheet by the suction pad, so that the protective sheet can be fallen by a necessary and sufficient amount. Therefore, it is possible to stabilize the contact state between the protection sheet and the suction pad and securely hold the protection sheet by suction. Further, since the friction surface acting on the protective sheet can be reduced by pushing the changing surface together with the protective sheet, it is possible to prevent the protective sheet from falling off the suction pad.

  Moreover, in the laminated body pallet integrated product according to the present invention, the changing surface may be deformed according to the pressing.

  In this way, the changing surface is formed of an elastic body such as rubber or sponge, and is configured to be deformed according to the pressing, so that the protective sheet can be surely fallen down by a necessary and sufficient amount according to the pressing of the suction pad. In addition, the frictional resistance acting on the protective sheet can be reliably reduced.

  Further, in the laminated pallet integrated product according to the present invention, the change surface may move in accordance with the pressing.

  By configuring the changing surface to move in accordance with the pressing in this way, the protective sheet can be reliably fallen by a necessary and sufficient amount in accordance with the pressing of the suction pad, and acts on the protective sheet. Friction resistance can be reliably reduced.

  Further, in the laminated pallet integrated product according to the present invention, the change surface may be formed of a plate-shaped member, and the plate-shaped member may be configured to be tiltable around an axis parallel to the support surface.

  In this way, if the change surface is formed of a plate-like member, the shape of the protection sheet when pressed is stabilized. For example, by making the surface of the plate-shaped member flat, the shape of the protective sheet when pressed is stable in a substantially flat shape. Therefore, it is possible to stably hold the protection sheet by the suction pad or the like. Further, according to the above configuration, the changing surface can be relatively easily provided in the second facing region. Therefore, the improvement of the pallet can be minimized, and the present technical problem can be solved at low cost.

  In the laminated pallet integrated product according to the present invention, the plate-shaped member may be urged in a direction against pushing.

  By configuring the plate member as described above, it is possible to automatically return the plate member to the position or posture before the pressing as the pressing is eliminated. Further, if only the plate-like member is urged, a very simple configuration is sufficient, so that the cost for improving the pallet can be suppressed.

  Moreover, in the laminated body pallet integrated product according to the present invention, the change surface may be formed of metal.

  In this way, by forming the changing surface with metal, the frictional resistance can be reduced as compared with rubber or sponge, and the changing surface has good durability. For this reason, it is possible to use a pallet having a changing surface for a long time.

  Moreover, in the laminated pallet integrated product according to the present invention, the change surface may be located above the first facing region.

  By providing the change surface above the first facing region, for example, when the protection sheet is lifted from the state of being held by suction and discharged out of the pallet, the change surface effectively functions. That is, since it is easier to secure a work space above the periphery of the pallet, by providing a change surface above the first facing area, it is possible to efficiently perform unpacking work in terms of work space, and In this case, the protective sheet can be smoothly discharged.

  Moreover, in the laminated pallet integrated product according to the present invention, the change surface may be rectangular and may be divided in the longitudinal direction.

  The holding position (the position where the protective sheet is pressed) of the protection sheet by the suction pad or the like is set at a predetermined position in advance, whereas the position and dimensions of the laminated body mounted on the pallet are not small for each product. Different. Therefore, when the suction pads arranged along the longitudinal direction (for example, the horizontal direction) of the rectangular changing surface are uniformly pushed toward the protective sheet at the same position, the pushing amount may differ in the longitudinal direction. On the other hand, by dividing the changing surface in the longitudinal direction as in the present configuration, for example, even when the changing surface is formed of a plate-like member, the degree of pushing of the changing surface in the longitudinal direction (this In this case, it is possible to make the degree of tilt of the plate-shaped member different for each plate-shaped member to absorb a variation in the pushing amount in the longitudinal direction.

  Further, the above object can be achieved by a pallet according to the present invention. That is, this pallet is a pallet capable of holding a stacked body in a state in which a plurality of glass plates and protective sheets are alternately stacked in a vertical position, and a support surface for supporting the back side of the stacked body in the vertical position. The support surface has a first facing region facing the glass plate, and a second facing region facing the portion of the protective sheet that protrudes from the glass plate, and has a second facing region. The region is characterized in that it has a changing surface that can be pushed.

  Thus, also in the pallet according to the present invention, of the support surface supporting the back surface of the laminated body in a state where the glass plate and the protective sheet are alternately laminated in the vertical posture, the protective sheet protruding from the glass plate and In the facing area (second facing area), a changeable surface that can be pushed is provided. Therefore, according to the above configuration, similarly to the integrated product according to the present invention, when the protective sheet and the glass plate are reduced, the changing surface is pushed together with the protective sheet by the suction pad, so that the protective sheet falls down by a necessary and sufficient amount. I can do it. Therefore, it is possible to stabilize the contact state between the protection sheet and the suction pad and securely hold the protection sheet by suction. Further, since the friction surface acting on the protective sheet can be reduced by pushing the changing surface together with the protective sheet, it is possible to prevent the protective sheet from falling off the suction pad.

  As described above, according to the laminated pallet integrated product and the pallet according to the present invention, when the protective sheet such as the interleaving paper is discharged from the laminated body on the pallet, even when the interleaving paper is reduced, It is possible to stably hold and hold the slip sheet.

<First embodiment of the present invention>
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. In all of the following embodiments, a glass plate to be laminated is used as a glass substrate for a flat panel display, and a laminated body in a state where the glass substrates are laminated via interleaving paper is mounted on a pallet. Will be described as an example.

  FIG. 1 is a perspective view of a laminated pallet integrated product 1 according to a first embodiment of the present invention. 2 is a side view of the laminated pallet integrated product 1, and FIG. 3 is a view of the laminated pallet integrated product 1 viewed from the direction of arrow A shown in FIG. As shown in FIGS. 1 to 3, the laminated body pallet integrated product 1 includes a pallet 2 and a laminated body 3 mounted on the pallet 2.

  Here, the laminated body 3 is formed by alternately laminating a plurality of glass plates G and the slip sheets I in a vertical posture (in this embodiment, an inclined posture). In the present embodiment, both the glass plate G and the slip sheet I have a rectangular shape, and the slip sheet I is disposed on the rearmost side of the laminate 3.

  Here, as an example of the specifications regarding the laminate 3, the size of the glass plate G is 730 mm × 920 mm to 2250 mm × 2600 mm, and the thickness of the glass plate G is 300 μm to 1100 μm. The interleaving paper I that forms the laminate 3 together with the glass plate G is, for example, pure pulp paper. The size (area) of the slip sheet I is usually larger than the glass sheets G, and the slip sheets I are alternately arranged with the glass sheets G so that the glass sheets G do not directly contact each other. Thereby, the laminated body 3 in a state where the glass plates G and the slip sheets I are alternately laminated is configured.

  The pallet 2 mainly includes a base portion 4 located on the bottom side 3a side of the laminate 3 and a back portion 5 located on the back surface 3b side of the laminate 3. In the present embodiment, the base 4 includes a bottom support 6 that supports the bottom 3 a of the multilayer body 3, and a receiving plate 7 that is disposed between the bottom support 6 and the multilayer 3. Further, the rear portion 5 stands up from the base portion 4 and supports a rear surface 3b of the multilayer body 3, and a buffer plate 9 disposed between the rear support portion 8 and the multilayer body 3. Having. The number of the receiving plate 7 and the buffer plate 9 described above may be one or plural. In the present embodiment, one receiving plate 7 and one buffer plate 9 are both provided on the bottom support portion 6 and the back support portion 8, respectively.

  As shown in FIG. 2, the upper surface 6 a of the bottom supporting portion 6 is inclined at a predetermined angle θ1 (for example, 5 ° to 25 °) with respect to the horizontal direction so as to shift upward as the distance from the rear portion 5 increases. I have. Also, as shown in FIG. 2, the front surface 8 a of the back support portion 8 moves backward at a predetermined angle θ2 (for example, 5 ° to 25 °) with respect to the vertical direction as the distance from the bottom support portion 6 increases. It is inclined. At this time, the front surface 8a of the back support 8 is, for example, substantially perpendicular to the upper surface 6a of the bottom support 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 θ1 formed by the upper surface 6a of the bottom support 6 with respect to the horizontal direction, and at least the glass plate of the front surface 9a of the buffer plate 9 is formed. The angle formed by the region facing G with respect to the vertical direction is the same as the angle θ2 formed by the front surface 8a of the back support 8 with respect to the vertical direction.

  In addition, both the receiving plate 7 serving as the buffer plate on the bottom side and the buffer plate 9 on the back side can be formed of a material having both appropriate buffering properties and mechanical strength such as foamed resin. As a specific example, both the receiving plate 7 and the buffer plate 9 are formed mainly of expanded polypropylene, expanded polyethylene, urethane (including expanded urethane and non-expanded urethane), expanded styrene, and expanded melamine.

  As shown in FIG. 3, the width direction dimension of the buffer plate 9 is smaller than the width direction dimension of the front surface 8a of the back support portion 8, and the upper portion and both side portions of the front surface 8a protrude from the buffer plate 9, respectively. It is in a state. Here, the width direction of the buffer plate 9 is the same as the width direction of the glass plates G stacked on the pallet 2 in the vertical posture, and is the longitudinal direction of the side of the glass plate G extending in the horizontal direction. At this time, the area of the laminate 3 is smaller than the area of the front surface 9a of the buffer plate 9, and when the laminate 3 is placed on the pallet 2 as shown in FIG. It is in a state of protruding from the laminate 3. As shown in FIG. 4, the upper portion of the buffer plate 9 protrudes from the glass plate G, while the slip sheet 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 via the slip sheet I.

  When the sizes of the glass sheet G and the slip sheet I are compared, the area of the glass sheet G is smaller than the area of the slip sheet I, and in a state where the glass sheet G and the slip sheet I are alternately stacked in the vertical posture, As shown in an enlarged manner in FIG. In this case, the plate member 10 is disposed adjacent to the upper end of the buffer plate 9, and the front surface 10a of the plate member 10 faces the portion of the slip sheet I protruding from the upper side of the glass plate G. I have. Although not shown, in this embodiment, the slip sheet I protrudes from the glass sheet G on both sides of the glass sheet G, and the front surface 9a of the buffer plate 9 is separated from the slip sheet I on both sides. It is in a state of extruding. As described above, in the present embodiment, the front surface 9a of the buffer plate 9 and the front surface 10a of the plate member 10 correspond to the support surface according to the present invention. Further, a region facing the entire surface of the glass plate G in the front surface 9a of the buffer plate 9 corresponds to the first facing region 11a according to the present invention, and the slip sheet protruding from the side of the glass plate G in the front surface 9a. The region facing I and the region facing the slip sheet I protruding from the upper side of the glass plate G in the front surface 10a of the plate-shaped member 10 correspond to the second facing region 11b according to the present invention.

  The second opposing area 11b is provided with a changeable surface 12 that can be pushed (see FIG. 4). In the present embodiment, a rectangular changing surface 12 is provided in a portion of the second opposing region 11b on the upper side of the glass plate G facing the interleaving paper I protruding from the glass plate G. In this case, the change surface 12 is formed by the front surface 10 a of the movable plate member 10, and the plate member 10 is connected to the back support portion 8 via the urging member 13, for example, to thereby provide a predetermined surface. It is urged in a direction against pushing in the direction. In the present embodiment, the upper end of the plate-shaped member 10 is connected to the back support portion 8 via the biasing member 13, so that the plate-shaped member 10 can be tilted around an axis extending in the horizontal direction at the upper end. Have been. More specifically, the inclination angle θ3 of the changing surface 12 with respect to the first facing region 11a changes according to the insertion of the slip sheet I. The biasing member 13 may be made of any material, for example, a compression coil, a torsion coil spring, a spring such as a thin plate spring, a rubber plate, or any other material as long as the biasing force can be generated in a direction against the pushing of the slip sheet I. Elements having a structure can be employed. In the present embodiment, the plate member 10 and the back support 8 are tiltably connected by the biasing member 13 and the plate member 10 is biased, but the plate member 10 is biased by a connecting member such as a hinge. The plate-shaped member 10 may be urged by an urging member such as a compression coil in a state where the plate-shaped member 10 is tiltably connected to the back support portion 8.

  Further, the front surface 10a (change surface 12) of the plate-shaped member 10 has a glass plate as it moves away from the first opposing region 11a in a state where no load (such as a pushing force) is applied (a state shown in FIG. 4). The front surface 10a is inclined with respect to the front surface 9a of the buffer plate 9 so as to retreat to a lower side (lower left side in FIG. 4) than the first facing region 11a in the stacking direction X of G. The inclination angle θ3 of the front surface 10a with respect to the first facing region 11a is set in an appropriate range with respect to a pressing direction Y (see FIG. 6) of the suction pad 14 as a holding unit described later. The size is set to a predetermined size such that the line direction substantially matches the pushing direction Y.

  The width dimension of the front surface 10a (change surface 12) is set so as to oppose, for example, the interleaving paper I protruding on the upper side of the glass plate G in the entire width direction thereof (FIGS. 1 and 3). See). The dimension of the front surface 10a in the direction orthogonal to the width direction (vertical direction in FIG. 3) is set, for example, so as to face the interleaving paper I protruding on the upper side of the glass plate G in the entire vertical region. Have been.

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

  The laminated pallet integrated product 1 having the above configuration is packed and shipped in a predetermined form, for example. FIG. 5 shows an example of a package 15 formed by packing the laminate 3 of the laminated pallet integrated product 1 according to FIG. As shown in FIG. 5, the package 15 is composed of the above-described laminated pallet integrated product 1, a belt 16 for binding the laminated body 3, and a presser disposed between the belt 16 and the front surface of the laminated body 3. A side stopper 18 is provided between the member 17 and the side of the stacked body 3 of the belt 16. At both ends in the longitudinal direction of the belt 16, for example, as shown in FIG. 1, in a state where the laminated body 3 is mounted at a predetermined position on the pallet 2 in a vertical posture, the hooks 19 provided on the back support portion 8 In the doubled state, it is fixed on the front surface of the holding member 17 by being fastened by a ratchet or the like (not shown). Thereby, the laminated body 3 is fixed to the pallet 2 in a state where the movement in the front, rear, left and right directions is restricted. At this time, as shown in FIG. 5, a frame plate 20 is placed on the foremost side of the laminate 3, and the frame plate 20, the laminate 3, and the pressing member 17 are connected to the back support portion 8 by the belt 16. May be pressed.

  At the shipping destination, the unpacking operation of the package 15 is performed, and the glass plate G is taken out from the laminate 3 on the pallet 2. Hereinafter, the procedure for discharging the slip sheet I when the glass sheet G is taken out will be described with reference to FIGS.

  The unpacking operation is performed by, for example, an unpacking device called an unpacker device. Here, the unpacker device includes a first suction pad (not shown) for vacuum-sucking the glass plate G and a second suction pad for vacuum-sucking the slip sheet I interposed between the glass plates G. 6 (a suction pad 14 shown in FIG. 6), the first suction pad holds the glass plate G on the laminate 3 by suction, takes out the glass plate G from the pallet 2, and performs the second suction The interleaf paper I is sucked and held by the pad (suction pad 14), and is discharged out of the pallet 2.

  Here, the operation of discharging the slip sheet I includes an operation of sucking and holding the portion of the slip sheet I protruding from the glass plate G with the suction pad 14 and an operation of retracting the sucked and held slip sheet I from the pallet 2. They are roughly divided into Specifically, as for the operation of sucking and holding the slip sheet I, for example, as shown in FIG. 6A, it is assumed that the slip sheet I falls down to the back support portion 8 side when the suction pad 14 is pushed in. Then, an operation of approaching the suction pad from obliquely above the direction perpendicular to the laminating direction X of the glass plate G is adopted. As described above, the suction pad 14 is pressed from the predetermined direction Y toward the portion of the slip sheet I located on the frontmost side of the laminate 3 protruding from the glass plate G. Then, with the suction pad 14 in close contact with the slip sheet I, the slip sheet I is vacuum-sucked, and the upper edge of the slip sheet I is held by the suction pad 14.

  Thereafter, the suction pad 14 is moved along the planar direction of the glass plate G while keeping the state in which the suction pad 14 is pressed into the slip sheet I, so that the slip sheet I is retracted from the laminate 3. In the present embodiment, as shown in FIG. 6B, the state in which the suction pad 14 is pushed into the slip sheet I is maintained by rotating the suction pad 14 around, for example, a predetermined axis extending in the horizontal direction. Then, the suction pad 14 is moved upward. Thus, the state of close contact with the glass plate G located on the back side of the slip sheet I is eliminated, and only the slip sheet I is discharged upward. The above operation is alternately repeated with the operation of taking out the glass plate G by the first suction pad (not shown), so that the glass plate G and the slip sheet I are discharged from the pallet 2 alternately.

  By the way, when the interleaf I is discharged from the pallet 2 by operating the suction pad 14 as described above, the contact state between the suction pad 14 and the interleaf I changes when the interleaf I and the glass plate G are reduced. Therefore, it is difficult for the pallet having the conventional configuration to stably hold the slip sheet I by suction. That is, when the suction pad 14 is always pushed toward the slip sheet I at a constant angle (the pushing direction Y), as shown in FIG. In the pallet 102 having the configuration, when the slip sheet I is pushed into the suction pad 14 in a state where the remaining slip sheet is low, the falling of the slip sheet I to the back side is restricted by the second facing region 11b (the front face 9a of the buffer plate 9). You. As a result, the falling angle of the slip sheet I when the suction pad 14 is pushed in becomes smaller than when the remaining number of slip sheets I is sufficient (see FIG. 6A) (see FIG. 8). In this case, a difference occurs between the pressing angle of the suction pad 14 and the falling angle of the slip sheet I, and the suction pad 14 comes into partial contact with the slip sheet I. Difficult to hold by suction.

  On the other hand, in the laminated pallet integrated product 1 according to the present invention, as shown in FIG. 4 and the like, the support surface (here, the front surface 9a of the buffer plate 9 and the plate-like member 10) supporting the back surface 3b of the laminated body 3 is provided. In the front surface 10a), a changeable surface 12 capable of being pushed is provided in a second facing region 11b facing the slip sheet I protruding from the glass plate G. According to the above configuration, since the change surface 12 is pushed together with the slip sheet I by the suction pad 14, the slip sheet I can be fallen by a necessary and sufficient amount (see FIG. 7). As described above, according to the laminated pallet integrated product 1 of the present invention, the contact state between the slip sheet I and the suction pad 14 is stabilized regardless of the remaining number of slip sheets I, and the slip sheet I is reliably sucked. It is possible to hold.

  Further, in the laminated body pallet integrated product 1 according to the present invention, the interleaf I can be supported while the pushing force to the back side acting on the interleaf I is absorbed by the changing surface 12. Therefore, when the interleaf I is moved in a direction along the surface of the glass plate G (a direction orthogonal to the laminating direction X) while the interleaf I is pushed to the rear side by the suction pad 14, the interleaf I acts on the interleaf I. Friction resistance can be reduced. As described above, according to the laminated pallet integrated product 1 of the present invention, it is possible to prevent the slip sheet I from coming off the suction pad 14 and to reliably discharge only the slip sheet I from the pallet 2. .

  Further, in the present embodiment, the changing surface 12 is formed by the front surface 10a of the movable plate member 10, and the plate member 10 is tilted about an axis parallel to the first facing region 11a serving as the support surface of the glass plate G. Configured to be possible. As described above, if the changing surface 12 is formed by the front surface 10a of the plate member 10, the shape of the slip sheet I when pushed is stabilized in a state following the shape of the plate member 10. Therefore, the slip sheet I can be stably held by the suction pad 14. Further, according to the above configuration, the slip sheet I can be fallen down to an appropriate posture (falling angle) according to the depression of the suction pad 14. This makes it possible to stabilize the contact state between the suction pad 14 and the interleaf I, so that it is possible to discharge the interleaf I in a more reliably sucked and held state while reducing frictional resistance.

  Further, in the present embodiment, since the plate-like member 10 is urged in a direction against the pushing, the pushing of the sheet-like member 10 to the back side of the interleaving paper I is canceled, It is possible to automatically return to the position or posture before pressing (for example, return from the posture shown in FIG. 7 to the posture shown in FIG. 4). Therefore, even when the pressing state of the interleaf I changes depending on the remaining number of the interleaf I, the frictional resistance acting on the interleaf I can be stably reduced. Further, if only the plate-like member 10 is urged, a very simple configuration is sufficient, and the cost for improving the pallet can be suppressed.

  Further, in the present embodiment, the front surface 10a (change surface 12) of the plate-shaped member 10 moves from the first opposing region 11a in a state where no load (such as a pushing force) is applied (a state shown in FIG. 4). The front surface 10a is inclined with respect to the front surface 9a of the buffer plate 9 such that the front surface 10a retreats to a lower side (lower left side in FIG. 4) than the first facing region 11a in the stacking direction X of the glass sheets G as the distance increases. This makes it easy for the slip sheet I to fall down when the suction pad 14 is pushed in, so that the contact state between the slip sheet I and the suction pad 14 is further stabilized, regardless of the number of remaining sheets of the slip sheet I, and more reliable. In this case, the slip sheet I can be held by suction. When the front surface 10a (change surface 12) of the plate member 10 is inclined with respect to the front surface 9a of the buffer plate 9 as described above, the inclination angle θ3 of the front surface 10a (change surface 12) of the plate member 10 is the modulus of the front surface 10a. It is preferable that the line direction is set so as to substantially coincide with the pushing direction Y. In this case, it is preferable to make the buffer plate 9 thick enough to ensure the inclination of the front surface 10a of the plate member 10.

  As described above, the laminated pallet integrated product and the first embodiment of the pallet according to the present invention have been described. However, the laminated pallet integrated product and the pallet may take any form within the scope of the present invention. it can.

<Second embodiment of the present invention>
For example, in the first embodiment, the case where the movable plate 12 is provided adjacent to the upper end of the buffer plate 9 and the movable surface 12 is formed on the front surface 10a of the plate 10 has been described. Of course, other forms are also possible. FIGS. 9A and 9B are enlarged side views of a main part of the laminated pallet integrated product 21 according to the second embodiment of the present invention. As shown in FIG. 9A, in the laminated body pallet integrated product 21 according to the present embodiment, the front surface 8 a of the back support portion 8 has a second facing area 11 b facing the slip sheet I, and a front surface 8 a. The recess 22 is provided in a recessed state, and the plate member 10 is mounted on the recess 22. Also in this case, the changing surface 23 is formed on the front surface 10 a of the movable plate member 10, and the upper end of the plate member 10 is connected to the inner surface of the recess 22 via the biasing member 13, The plate member 10 can be tilted within the recess 22. According to the above configuration, for example, a space allowing the tilting of the plate-shaped member 10 is made larger than that of the case where the tiltable plate-shaped member 10 is provided on the front surface 8a of the back support portion 8 (see FIG. 4). (See FIG. 9B). As a result, the allowable range of the pressing angle and the pressing amount of the suction pad 14 can be widened. Therefore, while stably holding the interleaf sheet I, the pressing force is absorbed to reduce the frictional resistance. Only the slip sheet I can be discharged from the pallet 2. In FIG. 9, the lower end of the front surface 10 a of the plate member 10 is set slightly lower than the front surface 9 a (first opposing region 11 a) of the buffer plate 9, but may be set higher. Alternatively, the lower end of the front surface 10a of the plate member 10 and the front surface 9a of the buffer plate 9 may be at the same height.

  In the present embodiment, the front surface 10a (change surface 23) of the plate-shaped member 10 has a front surface of the buffer plate 9 in a state where no load (such as a pushing force) is applied (a state shown in FIG. 9A). Parallel to 9a. Further, in the present embodiment, the plate-like member 10 can be tilted about the upper end thereof as a fulcrum. For this reason, when the interleaf paper I and the glass plate G are reduced, when the suction pad 14 is pressed, the pressing direction Y of the suction pad 14 (the normal direction of the suction surface) and the normal direction of the front surface 10a shift. However, in the process of rotating the suction pad 14 about a predetermined axis extending in the horizontal direction, the angle of the suction pad 14 changes, and the normal direction of the suction surface of the suction pad 14 matches the normal direction of the front surface 10a. . This makes it possible to reliably hold and hold the slip sheet I regardless of the remaining number of slip sheets I.

  In the case where the concave portion 22 is provided in the rear supporting portion 8 as in the present embodiment, it is preferable that the rear supporting portion 8 is formed in a box shape having a hollow inside. Thereby, the rigidity of the back support portion 8 can be secured without providing a beam, so that the recess portion 22 can be easily provided.

<Third embodiment of the present invention>
Further, in the above-described first and second embodiments of the present invention, the case where the plate-shaped member 10 is tilted with the upper end of the plate-shaped member 10 as a fulcrum is exemplified. However, other forms are naturally used. It is also possible. FIGS. 10A and 10B are enlarged side views of a main part of the laminated pallet integrated product 31 according to the third embodiment of the present invention. As shown in FIG. 10A, the plate member 10 according to the present embodiment is mounted on a recess 22 provided on the front surface 8a of the back support 8 as in the second embodiment. On the other hand, the plate-shaped member 10 is connected at its lower end to the inner surface of the recess 22 via the biasing member 13. As a result, the plate-shaped member 10 can be tilted with its lower end as a fulcrum, so that the changing surface 32 formed by the front surface 10a of the plate-shaped member 10 can also be tilted with its lower end as a fulcrum (see FIG. b)). Also according to this configuration, a large space for allowing the plate member 10 to tilt can be provided on the rear side of the plate member 10. As a result, the allowable range of the pressing angle and the pressing amount of the suction pad 14 can be widened. Therefore, while stably holding the interleaf sheet I, the pressing force is absorbed to reduce the frictional resistance. Only the slip sheet I can be discharged from the pallet 2.

  In the present embodiment, the front surface 10a (change surface 32) of the plate-shaped member 10 has the front surface of the buffer plate 9 in a state where no load (such as a pushing force) is applied (a state shown in FIG. 10A). Parallel to 9a. Further, the plate-shaped member 10 of the present embodiment can be tilted with the lower end of the plate-shaped member 10 (the end closer to the first facing region 11a) as a fulcrum. For this reason, when the interleaf I and the glass plate G are running low, the suction pad 14 pushes the change surface 32 together with the interleaf I, or the suction pad 14 rotates around a predetermined axis extending in the horizontal direction. The normal direction of the suction surface of the suction pad 14 matches the normal direction of the front surface 10a. This makes it possible to reliably hold and hold the slip sheet I regardless of the remaining number of slip sheets I.

<Fourth embodiment of the present invention>
Further, in the above-described embodiment, the case where the plate-shaped member 10 can be tilted and the changing surfaces 12, 23, 32 formed by the front surface 10a of the plate-shaped member 10 are moved (tilted) is exemplified. Other forms are also possible. FIGS. 11A and 11B are enlarged side views of a main part of a laminated pallet integrated product 41 according to a fourth embodiment of the present invention. As shown in FIG. 11A, in the laminated pallet integrated product 41 according to the present embodiment, an elastic plate 42 is provided adjacent to the upper end of the buffer plate 9 and changes at the front surface 43 of the elastic plate 42. A surface 44 is formed. In this case, the front surface 9a of the buffer plate 9 and the front surface 43 of the elastic plate 42 correspond to the support surface according to the present invention. The elastic plate 42 is made of, for example, a material that is more easily deformed than the buffer plate 9, specifically, an elastic body (rubber, sponge, or the like) whose front surface 43 can be deformed in response to the pressing of the suction pad 14. According to the above configuration, it is possible to more flexibly cope with the pressing of the interleaving paper I during suction. Therefore, even when the pressing mode by the suction pad 14 is not stable, the frictional resistance can be reliably reduced.

<Fifth embodiment of the present invention>
FIG. 12 is a perspective view of a laminated pallet integrated product 51 according to a fifth embodiment of the present invention. In FIG. 12, the laminate 3 is drawn by a two-dot chain line. The laminated pallet integrated product 51 according to the present embodiment is different from the laminated pallet integrated product 1, 21 according to the embodiment in that the rectangular changing surfaces 52a to 52c are divided in the longitudinal direction as a whole. 31 and 41 are different. Specifically, changing surfaces 52a to 52c are formed by front surfaces 53a1 to 53c1 of a plurality of plate-like members 53a to 53c which are divided in a horizontal direction and movable independently (in this embodiment, tilted). According to the above configuration, even when the amount of insertion of the slip sheet I by the suction pad 14 (see FIG. 6 and the like) varies in the horizontal direction, the degree of tilt of the plate members 53a to 53c is determined by the plate members 53a to 53c. Variations can be made for each 53c to absorb variations in the pushing amount in the horizontal direction. Therefore, according to the present configuration, it is possible to effectively reduce the frictional resistance acting on the slip sheet I over the entire area in the horizontal direction while absorbing the variation in the pressing amount in the horizontal direction. Although FIG. 12 illustrates the case where the changing surface is divided into three parts in the horizontal direction, it is needless to say that the plane may be divided into two parts or four parts or more in the horizontal direction depending on the application.

  Needless to say, the forms of the change surfaces 12, 23, 32, 44, 52a to 52c are arbitrary, and can take forms other than the above-described examples as long as pushing is possible. For example, although not described in detail, the plate-like member 10 shown in FIG. 4 approaches the back support 8 without changing the inclination angle θ3 in response to the depression, in other words, the inclination angle θ3 is constant and parallelly moves in the stacking direction X. It is also possible to configure so that

  In the above description, in the case where the changing surfaces 12, 23, 32, 44, 52a to 52c are provided in the second facing region 11b in a region facing the slip sheet I protruding from the upper side of the glass plate G. However, the change surfaces 12, 23, 32, 44, and 52 can be provided at other positions. For example, although not shown in the drawing, when the slip sheet I protruding from the side of the glass plate G is sucked and held, and the slip sheet I is moved in the horizontal direction and discharged from the pallet 2, the second facing It is also possible to provide the change surfaces 12, 23, 32, 44, 52a to 52c in a region of the region 11b facing the slip sheet I protruding from the side of the glass plate G.

  Further, in the above description, the case where the slip sheet I is used as the protective sheet when the glass plates G are laminated is described, but it is needless to say that the present invention is not limited to this. For example, it is also possible to use paper other than interleaving paper as a protection sheet. Alternatively, a sheet made of a material other than paper (for example, resin) can be used as the protection sheet. The point is that, when the glass sheets G are mounted on the pallet 2 in a stacked state, or when the glass sheets G are taken out from the pallet 2, the glass sheets G can be protected (as long as the glass sheets G are not damaged). Sheets of the following materials and forms can be used.

  In the above description, the case where the laminated body pallet integrated product 1 is packed and transported to a shipping destination or the like in the state of the package 15 and unpacking (take-out of the glass plate G) is performed at the transport destination has been exemplified. The laminated body pallet integrated products 1, 21, 31, 41, 51 according to the present invention can be applied to uses other than the above. That is, as long as the glass plates G are stacked on the pallet 2 in a vertically stacked state when the glass plate G is taken out, the form is arbitrary, and the pallet 2 is always a form premised on packing. No need. For example, although not shown, the glass plates G (laminated body 3) are stacked in a horizontal posture during transport, and the glass plates G are stacked in a vertical posture during removal of the glass plate G. The present invention may be applied to a completed pallet.
