Description

  The present invention relates to a technique for improving a glass plate packing pallet for packing a glass plate laminate in which a plurality of glass plates are stacked in a vertical posture.

  In recent years, as represented by glass substrates for flat panel displays (FPD) such as liquid crystal displays, plasma displays, and organic EL displays, various types of glass plates are required to be further increased in size and thickness. However, as the enlargement and thinning of the glass plate are promoted, handling of the glass plate during transportation becomes inevitably difficult. Therefore, it is the actual situation that the importance of the packaging form of the glass plate adopted when transporting the glass plate is further increased.

  And reflecting such a situation, as a packaging form of this type of glass plate, for example, as disclosed in Patent Document 1, it is erected at a base part and a rear position of the base part. A form in which a plurality of glass plates are stacked in a vertical posture (hereinafter also referred to as a glass plate laminate) on a substantially L-shaped pallet including the back surface portion as a basic component. More and more are being adopted.

  Moreover, in patent document 1, the glass plate laminated body supported by the base part and the back part (back support part) in this way is hold | maintained on a pallet by pressing from the front side to the back side by a holding part. Is disclosed. In detail, the holding part is a support member (guide member) that extends forward from the back surface through both sides of the glass plate laminate from both ends of the front pressing member (pressing member) that presses the front surface of the glass plate laminate. ).

JP 2006-347592 A

  By the way, in the packing form disclosed in Patent Document 1, since the front side of the glass plate laminate is pressed against the back side by the front pressing member and held on the pallet, the glass plate laminate is caused by vibration during transportation. It is unlikely that the glass plate included in will be displaced in the front-rear direction (stacking direction).

  However, in the packaging form, the glass plate included in the glass plate laminate is not directly restricted in movement in the surface direction by the front pressing member, and thus is displaced in the surface direction due to vibration during transportation. easy. And when the glass plate is displaced in the vertical direction, the displacement is corrected to its original state by its own weight, but when the glass plate is displaced in the width direction, the displacement is later It is difficult to correct. Therefore, once the deviation in the width direction occurs once in the glass plate included in the glass plate laminate, the deviation in the width direction is likely to remain even when the glass plate is taken out from the pallet after transportation. This is a cause of serious problems such as inability to work when taking out.

  Therefore, it is desirable to take measures to prevent the deviation in the width direction as well as the deviation in the front-rear direction of the glass plates included in the glass plate laminate, but by taking such measures, loading and unloading of the glass plates is desired. It is important to ensure that work is not hindered.

  In view of the above circumstances, the present invention is a glass that can reliably suppress the displacement in the front-rear direction and the width direction of the glass plate at the same time without hindering the loading and unloading operations of the glass plate included in the glass plate laminate. It is a technical problem to provide a pallet for board packing.

  In order to solve the above-mentioned problems, the present invention provides a base part that supports the lower surface of a glass plate laminate in which a plurality of glass plates are laminated in a vertical posture, and the glass that stands on the base part and is provided on the base part. A glass provided with a back surface portion that supports the back surface of the plate laminate, a front pressing member that presses the front surface of the glass plate stack, and a support member that is attached to the back surface portion and supports both ends of the front pressing member. In the plate packaging pallet, the support member is provided with an outer surface pressing member that presses the outer surface existing at both ends in the width direction of the glass plate laminate, and the support member is detachably supported by the back surface portion. It is characterized by being.

  According to such a configuration, since the front surface of the glass plate laminate is pressed by the front pressing member supported by the support member, the movement of the glass plate included in the glass plate laminate in the front-rear direction is directly regulated, and the glass Deviation in the longitudinal direction of the plate is reliably suppressed. Moreover, since the outer surface pressing member which presses the outer surface which exists in the width direction both ends of a glass plate laminated body is provided in the support member which supports this front surface pressing member, the width direction of the glass plate contained in a glass plate laminated body The movement of the glass plate is directly regulated, and the displacement in the width direction of the glass plate is also reliably suppressed.

  Since the support member provided with the outer surface pressing member is detachably supported by the back surface portion, the engagement state between the support member and the back surface portion is released, and the support member can be detached from the back surface portion. In this case, the outer surface pressing member is removed from the back surface portion integrally with the support member. Therefore, if the glass plate loading and unloading operations are performed in this state, the support member and the outer surface holding member do not interfere with these operations, and the workability of the glass plate loading and unloading operations is improved. It can be maintained well.

  Said structure WHEREIN: It is preferable that the said outer surface pressing member is comprised so that position adjustment is possible in the width direction.

  If it does in this way, it can position in the state which made the outer surface pressing member contact | abut to the outer surface of a glass plate laminated body reliably. Therefore, even when the size of the glass plate constituting the glass plate laminate is changed, it is possible to reliably prevent the shift in the width direction of the glass plate after the change. Therefore, the advantage that a common pallet can be used for glass plates of different sizes can be enjoyed, and the versatility of the pallet is improved.

  Said structure WHEREIN: The said outer surface pressing member makes the outer surface plate contact | abutted to the said glass plate laminated body, and moves this outer side plate to the width direction with respect to the outer surface of the said glass plate laminated body. And an operation unit.

  In this case, it is preferable that the operation unit is configured to convert a manual rotation operation into the approaching movement and the separation movement of the outer face plate.

  If it does in this way, it will become possible to perform precise position adjustment of an outside face board by rotation operation of an operation part.

  In the above configuration, the glass plate laminate is divided into a plurality of portions in the width direction, and is arranged at intervals in the width direction, between the inner side surfaces of the divided glass plate laminates. An intermediate presser member whose width dimension can be adjusted may be interposed in the gap.

  In this way, when a plurality of glass plate laminates are arranged and packed on one pallet, each glass plate is kept in a state where the inner side surfaces of adjacent glass plate laminates are separated from each other. Deviation in the width direction of the glass plate included in the laminate can be reliably prevented.

  In this case, the intermediate presser member moves toward and away from the pair of inner side plates opposed to each other in the width direction and abutted against the inner side surface of the glass plate laminate, and the pair of inner side plates. It may be provided with a link mechanism for making it recoil.

  If it does in this way, since the space | interval of an inner surface board can be easily adjusted by operation of a link mechanism, an inner surface board can be made to contact | abut reliably to the inner surface of a glass plate laminated body. Therefore, it is very advantageous also in preventing the displacement of the glass plate in the width direction.

  Further, the intermediate pressing member may be composed of a plurality of wedge-shaped members whose tapered surfaces are abutted with each other, and the width-direction dimension may be adjusted by the wedge action of these wedge-shaped members.

  In this way, there is an advantage that the intermediate pressing member has a simple configuration.

  Said structure WHEREIN: It is preferable that the said glass plate is a glass substrate for flat panel displays whose length of 1 side is 1 m or more and plate | board thickness is 0.5 mm or more and 3 mm or less.

  As described above, according to the present invention, it is possible to reliably suppress the displacement in the front-rear direction and the width direction of the glass plate at the same time without hindering the loading and unloading operations of the glass plate included in the glass plate laminate. it can.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  As shown in FIG. 1, the pallet for glass plate packaging which concerns on one Embodiment of this invention is fundamentally comprised of the base part 1 and the back part 2 standingly arranged in the back position of this base part 1. As shown in FIG. It has a substantially L shape provided as an element.

  On the pallet, two glass plate laminates G in which a plurality of glass substrates are laminated in a vertical posture are arranged in parallel in the width direction. Under the present circumstances, the base part 1 played the role which supports the lower surface of the glass plate laminated body G from the downward direction, and the back surface part 2 is the glass plate laminated body inclined back in the state where the lower surface was supported by the base part 1. It plays the role of supporting the back of G. In addition, between the glass plates contained in each glass plate laminated body G, the protection sheet (interleaf paper etc.) which is not illustrated is interposed. Moreover, the glass plate contained in one glass plate laminated body G and the glass plate contained in the other glass plate laminated body G may each be a different size.

  And each glass plate laminated body G arrange | positioned on a pallet in this way is front, left and right by the front pressing member 3, the side pressing member 4, and the intermediate pressing member 5, as shown in FIG.1 and FIG.2. It is held on the pallet while being pressed from a total of three directions on both sides. Hereinafter, each configuration will be described in detail.

  In this embodiment, two front pressing members 3 are arranged on the front surface of two adjacent glass plate laminates G with an interval in the vertical direction. Each front pressing member 3 includes a front pressing bar 31, A front plate 32 is provided as a main component. The number of front pressing members 3 is not particularly limited, and can be appropriately changed according to the size of the glass plate included in the glass plate laminate G.

  The front presser bar 31 is disposed on the front surface of two adjacent glass plate laminates G in a state straddling the width direction. Both end portions of the front presser bar 31 protrude to the outer surface side of the two glass plate laminates G, and both protruding portions extend from both side surfaces of the back surface portion 2 to the front side. 6 is supported from below. The front presser bar 31 supported by the support member 6 is fixed to the back surface portion 2 by a fastening body such as a lashing belt, for example.

  The front plate 32 is attached to a slide member 33 provided on the front presser bar 31 so as to be slidable in the width direction (longitudinal direction) via a screw member 34 as a positioning operation portion in the front-rear direction. Therefore, the position of the front plate 32 can be adjusted in the width direction by a slide operation of the slide member 33, and the position of the front plate 32 can be adjusted in the front-rear direction by a rotation operation of the screw member 34. Therefore, if the position of the front plate 32 is adjusted by the slide member 33 and the screw member 34, the front surface of the glass plate laminate G can be reliably secured regardless of the number and size of the glass plates included in the glass plate laminate G. Can be pressed. In addition, as shown in FIG. 2, the front plate 32 presses the front surface of the glass plate laminated body G via the buffer body X1.

  As shown in FIG. 2, the outer surface pressing member 4 includes an outer surface plate 41 that comes into contact with outer surfaces existing at both ends in the width direction of the glass plate laminate G. The outer face plate 41 is attached to the support member 6 via a screw member 42 as a positioning operation portion in the width direction. Therefore, the position of the outer face plate 41 can be adjusted in the width direction of the glass plate laminate G by rotating the screw member 42. Therefore, when the position of the outer face plate 41 is adjusted by the screw member 42, the outer face plate 41 reliably presses the outer face of the glass plate laminate G regardless of the size of the glass plate included in the glass plate laminate G. be able to. In addition, the outer surface plate 41 presses the outer surface of the glass plate laminated body G through the buffer body X2.

  As shown in FIGS. 1 and 2, the intermediate presser member 5 is disposed between the opposed inner side surfaces of the two glass plate laminates G arranged in parallel. As shown in FIGS. 3A and 3B, the intermediate pressing member 5 includes a pair of opposed inner side surface plates 51 and a link mechanism 52 that adjusts the interval W between the inner side surface plates 51. The link mechanism 52 includes a handle 53 as a rotation operation unit, and a shaft portion 54 coupled to the handle 53 so as to be integrally rotatable. A first moving body 55 that slips without following the rotation of the shaft portion 54 when the shaft portion 54 is rotated is extrapolated at the tip of the shaft portion 54. Further, a second moving body in which a female screw engaging with a male screw formed on the outer peripheral surface of the shaft portion 54 is formed on the inner peripheral surface between the distal end and the base end (the handle 53 side) of the shaft portion 54. 56 is extrapolated. The 1st moving body 55 and the 2nd moving body 56 are arrange | positioned in the space between a pair of opposing inner surface plates 51, and the 1st moving body 55 and each inner surface plate 51 are 1st links. The second moving body 56 and each inner side plate 51 are connected by a second link member 58 while being connected by a member 57. One end of the first link member 57 is pinned to the inner side plate 51 so as to be swingable, and the other end of the first link member 57 is pinned to the first moving body 55 so as to be swingable. Yes. Also, one end of the second link member 58 is pinned to the inner side plate 51 so as to be swingable, and the other end of the second link member 58 is pinned to be swingable to the second moving body 56. Has been.

  When the intermediate presser member 5 configured as described above rotates the shaft portion 54 by operating the handle 53, the first moving body 55 is held at the tip end of the shaft portion 54 while idling at the tip end of the shaft portion 54. Only the second moving body 56 moves in the axial direction of the shaft portion 54 along the male screw of the shaft portion 54. Therefore, when the shaft portion 54 is rotated (forward rotation) in a predetermined direction, the second moving body 56 approaches the first moving body 55, and when the shaft portion 54 is rotated (reverse rotation) in the opposite direction, The second moving body 56 is separated from the first moving body 55. Then, when the shaft portion 54 is rotated in a direction in which the second moving body 56 approaches the first moving body 55 by the operation of the handle 53, as shown in FIG. As the 55 and the second moving body 56 approach each other, the inclination angle of the first link member 57 and the second link member 58 with respect to the shaft portion 54 gradually increases, and the interval W between the opposed inner side surface plates 51 increases. spread. At this time, the inclination angle of the first link member 57 and the inclination angle of the second link member 58 increase or decrease at the same rate, and the interval W of the inner side surface plate 51 is changed to any size. Even so, the opposing inner side plate 51 is kept parallel. Therefore, if the interval W between the inner side plates 51 of the intermediate presser member 5 is adjusted as described above, the inner side plate 51 allows the inner side plate 51 to move inside the glass plate laminate G regardless of the size of the glass plate included in the glass plate laminate G. The side surface can be reliably pressed. In addition, the inner surface board 51 presses the inner surface of the glass plate laminated body G through the buffer body X3 as shown in FIG.

  Therefore, since the periphery of each glass plate laminated body G is reliably pressed by the front surface pressing member 3, the outer surface pressing member 4, and the intermediate pressing member 5 as described above, it is included in each glass plate laminated body G. It is possible to reliably prevent the displacement of the glass plate in the front-rear direction and the width direction.

  Further, as shown in FIGS. 4A and 4B, the support member 6 is detachably attached to a front beam 21 and a rear beam 22 constituting the back surface portion 2. Specifically, as shown in FIG. 5A, the support member 6 includes a first claw 61 that engages with the front bar 21 and a second claw 62 that engages with the rear bar 22. . The first claw 61 has an L shape that engages with the back surface and the inner side surface of the front beam 21, and the second claw 62 has an L shape that engages with the front surface and inner surface of the rear beam 22. A first stopper 23 that restricts the lowering of the first claw 61 is attached to the front rail 21, and a second stopper 24 that regulates the upward movement of the second claw 62 is attached to the rear rail 22. It has been. Since the outer surface pressing member 4 and the like are provided at the distal end side of the support member 6, the distal end side of the support member 6 is heavier than the proximal end side, and the center of gravity of the support member 6 is at the distal end side (first side). It is biased to the front end side). As a result, with the support member 6 attached to the front beam 21 and the rear beam 22 as described above, a rotational force that lowers the front end of the support member 6 acts on the support member 6. Therefore, by this rotational force, the first claw 61 is pressed against the first stopper 23 while being biased downward, and the second claw 62 is pressed against the second stopper 24 while being biased upward. Therefore, the support member 6 is supported by the front beam 21 and the rear beam 22 while maintaining the posture in which the rotational force is restricted by the stoppers 23 and 24.

  On the other hand, if the support member 6 is rotated in a direction opposite to the rotational force, that is, the tip of the support member 6 faces upward, the engagement state of the first pawl 61 and the front bar 21 and the second The engagement state of the claw 62 and the rear beam 22 is released, and the support member 6 can be easily detached from the front beam 21 and the rear beam 22. Therefore, the outer surface pressing member 4 can be easily detached from the back surface portion 2 integrally with the support member 6.

  Therefore, even if the outer surface pressing member 4 is provided, if the outer surface pressing member 4 is removed from the back surface portion 2 integrally with the support member 6, it interferes with the workability of loading and unloading the glass plate. Therefore, the workability can be maintained satisfactorily.

  In addition, this embodiment is not limited to said embodiment, It can implement with a various form. For example, in the above embodiment, the case where two glass plate laminates G are packed on a pallet has been described. However, the glass plate laminate G packed on a pallet according to the size of the glass plate to be packed. The number of can be changed as appropriate. That is, when laminating a large glass plate to form a glass plate laminate G, the intermediate presser member 5 may be removed and only one glass plate laminate G may be arranged and packaged on the pallet. Moreover, when laminating | stacking a small glass plate and setting it as the glass plate laminated body G, while arrange | positioning three or more glass plate laminated bodies G on a pallet, between the inner side surfaces which the adjacent glass plate laminated body G opposes The intermediate presser member 5 may be arranged and packaged. In this way, since glass plates of various sizes can be packed with one pallet, the versatility of the pallet can be improved.

  Further, in the above embodiment, in the intermediate presser member 5, the first moving body 55 and the second moving body 56 are moved closer to and away from each other. Although the configuration in which only the body 56 moves along the shaft portion 54 has been described, both the first moving body 55 and the second moving body 56 move along the shaft portion 54 as the shaft portion 54 rotates. It is good also as composition to do. Specifically, for example, male screws (right screw and left screw) having different directions are formed on the distal end side and the proximal end side of the outer peripheral surface of the shaft portion 54, and the female screw meshing with one of the male screws is the first. If an internal thread formed on the inner peripheral surface of one moving body 55 and meshing with the other male screw is formed on the inner peripheral surface of the second moving body 56, the first moving body is accompanied by the rotation of the shaft portion 54. Both 55 and the second moving body 56 can be moved toward and away from each other while being moved.

  Moreover, in said embodiment, although the thing using a link mechanism was demonstrated as the intermediate pressing member 5, as shown in FIG. 5, the intermediate pressing member 5 opposes the adjacent glass plate laminated body G, for example. You may comprise from a pair of wedge-shaped member 59 arrange | positioned between inner surface. Specifically, the pair of wedge-shaped members 59 have inclined surfaces 59a that are in contact with each other, and the inclined surface 59a of the other wedge-shaped member 59 slides relatively along the inclined surface 59a of one wedge-shaped member 59. By doing so, the width-direction dimension W in a state where the two wedge-shaped members 59 are combined can be adjusted. If it does in this way, the inner side surface which the glass plate laminated body G opposes can be reliably pressed, without using complicated mechanisms, such as a link mechanism. For example, the wedge-shaped member 59 may be composed of three members. In this case, the central wedge-shaped member 59 is inserted between the wedge-shaped members 59 on both sides, and the wedge-shaped members 59 on both sides are inserted by the wedge action. It is good to make it the structure which moves to width direction.

  In the above embodiment, the case where the front presser bar 31 is provided with the front plate 32 movable in the width direction and the front-rear direction as the front presser member 3 has been described. As shown in FIG. 6, cushioning pressing members 35 and 36 may be laid on the front presser bar 31. In this case, the thickness of the pressing member 35 on the end side is preferably thinner than the thickness of the pressing member 36 on the center side. In this way, even if both front ends of the front presser bar 31 are pulled and fixed to the rear side by a fastening body such as a lashing belt, even if the front presser bar 31 bends, the front presser bar increases in deflection. Since the thickness of the pressing member 35 located on the end portion side of 31 is thinner than the thickness of the pressing member 36 located on the central portion side of the front presser bar 31 where the deflection is reduced, each pressing member 35, In 36, the front surface of the glass plate laminate G can be pressed substantially uniformly.
