Description

  The present invention packs a plate-shaped body, particularly a flat panel display (FPD), that is, a large-sized plate-shaped body for a liquid crystal display, a plasma display or the like, or a large-sized plate-shaped body of an intermediate product in the manufacturing process thereof, and then opens again after transporting. The present invention relates to a plate-shaped body packing box formed so as to be packed, and a plate-shaped body transport method, a plate-shaped body stacking method, and a plate-shaped body taking-out method using the plate-shaped body packing box.

  In recent years, needs for large plate glass used for FPD glass and the like are increasing. As a means for storing and transporting such a large plate glass, as shown in Patent Document 1, a packaging rack in which each plate glass is fixed in a state where a plurality of plate glasses are arranged upright is known.

  However, large plate glass having a height of 2.2 m or more, for example, cannot be stacked on a conventional track and requires a low floor track. Further, when transporting the plate glass in an upright state, the dimension of one side of the bottom surface is increased to ensure the stability of the packaging box (for example, 0.5 times the height of the packaging box). However, because the number of plate glasses that can be loaded in a single packaging box is limited due to the restrictions on the load capacity of forklifts and the floor load capacity of the manufacturing site, the volume and weight of the packaging box increase with respect to the number of plate glasses loaded. , Storage efficiency and transport efficiency are reduced.

  Patent Documents 2 and 3 disclose a packing method for storing a plurality of plate glasses in a flat position. Patent Document 2 describes that the movement of the plate glass can be controlled by sandwiching the plate glass with the foamed resin sheet, making the foamed resin sheet larger than the plate glass, and making it substantially the same as the storage space. However, when acceleration / deceleration, vibration, etc. of the track are applied, the glass plate is displaced from a predetermined position, making it difficult to perform automatic plate cutting in a subsequent process. Further, when the plate glass is greatly displaced, it comes into contact with the box, and the plate glass is defective such as chipping, wrinkling, and cracking.

  Cited Document 3 describes a packing method in which a plate glass is adsorbed and held by a support member. However, in this method, the storage efficiency is poor, the packaging case is complicated and expensive, and the operation is troublesome.

  The plate glass has been described above, but the same applies to plate-like bodies such as resin plates and metal plates.

As a result, the fork of the forklift can be received in the plate-like body packaging box 1 from both the vertical and horizontal directions of the rectangular pedestal.

  FIG. 5 is a schematic view showing a state in which the plate-like body packaging boxes 1 are stacked, and FIG. 6 is a partially enlarged view of the fitting portion A of the upper lid 2 and the base 3 when the plate-like body packaging boxes are stacked. FIG. The pedestal 3 is composed of a shaped steel lattice frame 30 as shown in FIG. 3, but as shown in FIGS. 5 and 6, the floor area is made narrower than the area of the upper lid 2, and the packaging box When stacking one by one, it is preferable that the base 3 is fitted inside the guide 8 of the upper lid.

  The upper material 5 is made of, for example, an iron plate, and is disposed to stably place the plate-like body 4 on the pedestal 3 and to prevent dust from entering the internal space that houses the plate-like body. preferable.

  The plate-like body protecting members 16 and 17 are fixed to the side plates 14 and 15 similarly to the base 3. The side plates 14 and 15 may be iron plates or iron square pipes. Since the plate-like body 4 is loaded so as to abut on the plate-like body protection members 16 and 17 fixed to the side plates 14 and 15, the position of the plate-like body in the horizontal direction can be determined with respect to the pedestal 3, and the rear It becomes easy to automatically take out the plate-like body 4 in the process. In order to facilitate the removal of the plate-like body 4 in the subsequent process, the side plates are arranged on two sides in the L shape, but the plate-like body protection fixed to the end surface portion of the plate-like body and the side plates 14 and 15 is provided. If the plate-like body is taken out from the state where the materials 16 and 17 are in contact with each other, the end face portion may be damaged by friction or the like. Therefore, the side plates 14 and 15 are preferably detachable.

  The material of the base 3 and the side plates 14 and 15 may be any material that can ensure the strength to support the plate-like body, and may be a non-ferrous metal such as aluminum or a non-metal such as resin. The plate-like body protection members 6, 16 and 17 are materials that can efficiently absorb, for example, a vibration frequency of 8 to 20 Hz in consideration of the frequency generated in the vehicle (or airplane) itself during land transportation or air transportation. Is preferred. For example, vibration absorbing materials such as rubber, silicone, and other various resins can be used.

  The upper lid 2 surrounds the outside of the plate-like body 4 stacked with an open bottom surface, and is composed of four side covers 12 and a top cover 13 as shown in FIG. An internal space S for storing the plate-like body is defined. The four side covers 12, the top cover 13 and the upper material 5 of the pedestal 3 can prevent foreign matters such as dust from entering the packing box. The side cover 12 and the top cover 13 may be made of steel, but the upper lid 2 needs to be attached and removed, so it is preferable that the cover is light. Therefore, the side cover 12 and the top cover 13 are made of steel only. A resinous film or plate is more preferable.

  The plate-like packaging box 1 is transported to a destination by, for example, a forklift, a truck, an airplane, etc. (hereinafter referred to as a conveying means). Accordingly, pressers 7 for holding the plate-like bodies 4 are arranged at the four corners of the upper lid 2 so that the individual plate-like bodies 4 do not move in the plate-like body packaging box 1 during the conveyance. FIG. 7 is a partial cross-sectional view of the presser. The presser 7 is preferably configured to urge the loaded plate-like body from above with a pressing force. For example, a trapezoidal screw 19 is screwed onto the upper lid 2 so that it can be screwed up with the head facing upward and the threaded portion facing downward, and a holding case 21 is fixed to the tip of the threaded portion of the trapezoidal screw 19 so as to be replaceable. . The holding case 21 has an open portion below, and a holding plate 22 that contacts the plate-like body is fixed to the open portion. Further, after screwing the trapezoidal screw 19, a nut 20 is screwed onto the trapezoidal screw 19 above the upper lid 2 in order to fix the position. Thereby, a plate-shaped object can be fixedly held with a fixed force. The holding plate 22 is made of an elastic material such as rubber. The presser 7 may be a spring, an air bag or the like.

  The arrangement of the presser 7 is not limited to the four corners, and may be one central place or two diagonal places, but four corners are more preferable particularly when the size of the plate-like body is large. In order to prevent the plate-like body from moving during conveyance, the pressing force when pressing at four locations is preferably, for example, 108 kg / one or more locations. By this presser 7, since each plate-like body 4 does not move in the plate-like body packaging box 1 at the time of conveyance, the plate-like body does not cause defects such as chipping, wrinkles, cracks, Further, the plate-like body can be easily taken out in the subsequent process.

  Further, when the plate-like body packaging box 1 is transported to a destination by, for example, a truck, an airplane, or the like (hereinafter referred to as a transport means), it is stored in a loading platform or a storage chamber of the transport means in a stacked state over a plurality of stages. . Accordingly, it is assumed that another plate-shaped packaging box is stacked on the top cover 13 of the upper lid 2, and an impact absorbing pad (buffer material) 9 for protecting the plate-shaped body is provided around the upper surface. Are pasted. The shock absorbing pad 9 is made of an elastic material such as rubber.

  At each corner of the top cover 13, a guide member 8 composed of two plates is placed on the top for positioning with the upper plate-like packaging box 1 placed as shown in FIGS. 5 and 6. The cover 13 is fixed on the top cover 13 so as to protrude above the square shock absorbing pad 8. As described above, the size of the top cover is larger than the pedestal floor area, and the upper plate-like packaging box 1 can be fitted and stacked between the guides fixed to the square of the top cover 13. When the box 1 is stored or moved, the upper plate-like package box 1 is not displaced or dropped, and the work can be performed efficiently and safely.

  The size of the plate-like body 4 to be stored is, for example, a large plate-like body having a plate thickness of 0.5 mm to 1.3 mm and a length and width of about 1800 mm × 2000 mm to 2400 mm × 2800 mm. Further, in flat stacking in the plate-shaped packaging box 1, in order to avoid the plate-shaped bodies 4 from coming into direct contact with each other, it is preferable that the thin sheets 18 are sandwiched between the plate-shaped bodies. . The interleaf paper 18 has a rough surface with a smoothness of 18 seconds or less (JIS P 8119, 1976), the contact area is reduced, the resin content in the interleaf paper is transferred to the plate-like body 4, and the paper surface on the glass surface. Paper quality that does not cause patterns, burns, stains, etc. is preferred. Further, the resin content of the interleaf paper 18 is 0.05% or less (JIS P 8205, 1976), and the paper quality is such that the quality of the plate-like body 4 itself is not adversely affected by the combined effect with the paper surface roughness described above. .

  Thus, the plate-like body 4 laminated on the plate-like body protection material 6 on the upper surface of the upper covering material 5 is provided on the upper lid 2 so as not to vibrate up and down on the plate-like body protection material 6 in the conveying process. The plate-like body 4 is pressed down with a constant force by the presser 7. As a result, even when the packaging box is transported, an impact is imposed from the outside, and even if the packaging box itself vibrates with the transportation, the plate-like body 4 is held in a stable state. In addition, a plate (not shown) such as resin, cardboard, or wood is used as a cushioning material so that the presser is in direct contact with the last flat plate that has been laid flat and no wrinkles or dirt is generated. Placed.

  As described above, the plate-like packaging box 1 according to the present embodiment can stably store a plurality of large plate-like bodies 4 in a flat stacked state. Moreover, the conveyance is performed in the state which piled up the same plate-shaped body packing box 1 on the multistage top and bottom with the plate-shaped body 4 being flatly stacked. As described above, by transporting the large plate-shaped body in a flat stacked state, it is possible to provide sufficient loading efficiency for a storage room or a delivery vehicle having a low ceiling height as compared with the conventional vertical transport mode. In addition, a large number of plate-like bodies can be stably conveyed by various transportation means.

  When the plate-like body 4 is loaded on such a plate-like body packaging box 1 or when the plate-like body 4 is taken out from the plate-like body packaging box 1 after conveyance, the plate-like body packaging box 1 is at a predetermined angle with respect to the horizontal plane. The packaging box 1 can be raised to form 0 to 90 degrees, preferably 75 to 85 degrees.

  FIG. 8 is an external perspective view of a tilting table for placing the packing box 1 and raising it at a predetermined angle, and FIGS. 9A and 9B are views showing the usage state of the tilting table. The raising / lowering base 23 is an L-shaped member that includes a large table portion 24 and a small table portion 25 that stands upright from one end portion of the large table portion 24. The raising / lowering base 23 is provided at a loading / unloading position of a predetermined plate-like body 4 on a conveyance path of a chain conveyor including a chain 26. The large table portion 24 and the small table portion 25 are formed with two parallel grooves 27 for passing the chain C of the conveyor along the packing box conveyance direction.

  When the packing box is transported, when the plate-shaped packing box 1 reaches the raising / lowering base 23 in which the large table portion 24 is in a horizontal state, the plate-shaped packing box 1 hits and is locked against the small table portion 25 as shown in FIG. . Thereafter, as shown in FIG. 9B, the raising / lowering base 23 is raised (arrow B). This standing angle can be appropriately adjusted between horizontal and almost right angles. This standing angle is adjusted to an optimum angle at which the operation of the robot for loading and unloading the plate-like body is smoothly performed.

  By using such a raising / lowering base 23 to load or take out the plate-like body 4 in a state where the plate-like body packaging box 1 is raised from the horizontal, the plate is directly removed from the plate-like body packaging box 1 in the horizontal state. Compared to the case where the plate-like body 4 is taken out or the plate-like body 4 is newly stacked on the plate-like body 4 in the plate-like body packing box 1, the handling of the plate-like body 4 itself is simpler. The plate-like body 4 can be easily extracted from the plate-like body packaging box 1 by human power, or the plate-like body 4 can be easily loaded on the plate-like body packaging box 1. In addition, the loading and unloading method of the plate-like body that loads or takes out the plate-like body in the state where the plate-like body packaging box 1 is raised in this manner can reduce the load on the plate-like body 4 and can damage the plate glass. Also decreases.

  The plate-like body packaging box of the present invention can be used again as it is after packing and transporting the plate-like body, unpacking after transportation and taking out the plate-like body. Such reuse can be repeated many times.
