Unexamined-Japanese-Patent No. 8-191723

  However, the storage rack described in Patent Document 1 is for storing lightweight and thin sheets such as large-sized paper, and is used still. Therefore, it is not suitable for applications such as storage of large-sized sheets that are heavy in weight and transportation of sheets to a work site for each storage rack.

  For example, when regularly inspecting a gas turbine, when overhauling the gas turbine on the turbine floor, large-scale flexibility such as a flame-retardant soft polyvinyl chloride sheet having a thickness of about 2 mm for curing the floor surface The use of sheet-like materials (hereinafter referred to as sheets) is under consideration. However, if it is a soft polyvinyl chloride sheet having a thickness of about 2 mm, its weight increases. For example, in the case of a soft vinyl chloride sheet of about 1000 × 1820 mm, it is about 6 kg per sheet. Moreover, about 4000 * 1820 mm, it will be about 24 kg per sheet. Moreover, disassembling and inspection of the gas turbine requires many sheets, for example, tens to hundreds of sheets. Therefore, if it is attempted to stack and store a certain number of sheets, the drawer type storage rack described in Patent Document 1 can not withstand its use. For example, even when relatively small soft vinyl chloride sheets of about 6 kg per sheet are stored in only about 50 sheets at a height of about 10 cm, it weighs about 300 kg, making it difficult to put them out in a drawer And not realistic. On the other hand, when it is going to store one soft vinyl chloride sheet for one drawer, a huge number of drawers are needed, the storage rack becomes large and handling becomes difficult, and there is a risk such as collapse. Increase.

  Moreover, in the cabinet type | forms sheet storage box which presupposes a deferred use, it can not respond, when it is necessary to move a storage box, such as tidying up and disassembly of sheets.

  On the other hand, in the case of sheets which are flexible and easily deformed, when they are stored upright, they have a problem that they are difficult to store because they can not retain their shape by bending and deforming. For this reason, there is a demand for storage in a flat place, that is, storage in a flat plate shape. Furthermore, even when storing in flat form, it is desirable to stack and store intensively.

  The present invention addresses such a demand, and stores large flexible sheet materials such as flexible vinyl chloride sheets and the like that are flexible and heavy in the form of flat plates, and also stacks and stores intensively. It aims to provide a sheet storage box that makes it possible. Another object of the present invention is to provide a sheet storage box suitable for carrying.

  A sheet storage box for achieving the purpose includes a case main body for stacking and storing sheets flatly, a convex portion formed on the periphery of the case main body and protruding in a direction perpendicular to a horizontal surface, and the case main body A cylindrical leg portion formed at the periphery and having a concave portion at the tip that projects coaxially with the convex portion and protrudes on the opposite side and into which the convex portion of the other case main body fits, and a suspension for suspending the case main body with a lifting and conveying device A convex portion and a cylindrical portion are provided with a lowering bracket or one or both of reinforcing members which reinforce the bottom of the case main body and which form a space in which the claws of the forklift can be inserted. The legs are engaged with each other and stacked so as not to shift in the horizontal direction.

  Further, the sheet storage box preferably has a tapered enlarged diameter portion in which the cylindrical leg portion also serves as a guide at the time of fitting of the convex portion on the opening end side.

  Further, it is preferable that the cylindrical leg portion of the sheet storage box and the reinforcing member have the same height, and the cylindrical leg portion and the reinforcing member support the case main body.

  Furthermore, the sheet storage box has casters that can be attached to and removed from the cylindrical legs, and when stacking the case main bodies, remove the casters, and when transporting the case main body, attach the casters to the cylindrical legs to make them bogies. Is preferred.

  Furthermore, the sheet storage box preferably includes a handle that is detachably attached to the case body.

  Here, the handle is removably attached to the case body by inserting the shaft portion into the handle insertion hole provided in the case body, the handle insertion holes are provided at least on two adjacent sides, and one of the sides is a handle It is preferable to attach and make it movable.

  Since the sheet storage box has a structure in which the convex portion and the tubular leg are fitted between the other case main bodies stacked on top of each other so as not to shift in the horizontal direction, it is flexible. A large flexible sheet such as a vinyl chloride sheet which is flexible and heavy can be stored as a flat plate, and can be collectively stored by stacking the case bodies.

  In addition, while the sheets necessary for the storage box are stored, the sheet can be moved to a desired location by a lifting conveyance device or a forklift. For this reason, it is possible to cope with the case where it is necessary to move the storage box, for example, at the time of cleaning up and separating sheets at the work site.

  In addition, when the caster and the handle are attached, the storage box also serves as a carriage, so it can be transported manually to the use place, and it is possible to remove the caster and the handle and carry it out as a storage box. .

  Hereinafter, the configuration of the present invention will be described in detail based on an embodiment shown in the drawings.

  1 to 6 show one embodiment of a sheet storage box according to the present invention. A sheet storage box (hereinafter simply referred to as a storage box) according to this embodiment includes a case main body 1 in which sheets 30 are stacked and accommodated flatly, a convex portion 2 projecting in a direction perpendicular to a horizontal surface, and And other cylindrical storage 4 having a recess 3 at the end, coaxial with the projection 2 and projecting on the opposite side and fitted with the projection 2 of the case main body 1 of the other storage box It is set as the structure laminated | stacked so that the recessed part 3 of the convex part 2 or the cylindrical leg part 4 may be fitted between a box, and a shift | offset | difference may not arise in a horizontal direction.

  The case body 1 has, for example, an open box shape having a bottom 5a and a circumferential side wall 5b for stacking and accommodating the sheets 30 flatly, and is appropriately reinforced if necessary. In the present embodiment, the case body 1 is in the form of an open box having an open top, but is not particularly limited thereto, and may be provided with an openable / closable lid or a removable lid.

  The shape of the case main body 1, particularly the shape seen from above the inner space for accommodating the sheets 30, is not limited to a specific shape, but the sheets 30 to reduce waste space and achieve compactness. In the case of the case main body 1 of the present embodiment for storing rectangular sheets 30, for example, it is preferable to use a rectangular box shape. The depth of the case body 1 is deeper than the stacking height of at least the number of sheets 30 scheduled to be stored so that the sheets 30 do not protrude. In the case of the present embodiment, a box 5 is formed into a box shape by bending the edges (defined by the notches) of one flat plate of a rectangular sheet having rectangular notches at the four corners (defined by the notches). The frame 5 is constituted by a frame of a chevron steel (hereinafter referred to as a circumferential frame 6) for reinforcing the edge of the box 5 all around, and is integrated by welding. The top surface of the case main body 1 refers to the highest surface of the case main body 1, that is, the upper surface parallel to the horizontal plane of the peripheral frame 6 in the present embodiment.

  In the case of the present embodiment, the bottom 5a of the case main body 1 is a flat plate and has a large number of holes 7 for weight reduction, drainage, etc. in order to stack and store the sheets 30 flatly. It is not limited and may be a non-porous flat plate. Further, the bottom 5a of the case main body 1 may be treated to avoid adhesion of the sheets 30, for example, by providing low streaks or shallow unevenness, or roughening the sheets 30 in order to facilitate removal of the sheets 30. good.

  In the case of the present embodiment, the convex portion 2 and the cylindrical leg portion 4 provided in the case main body 1 are provided with the convex portion 2 upward and the cylindrical leg portion 4 downward. For example, the upper surface of the case main body 1, that is, the upper surface of the peripheral frame 6 is provided with the convex portion 2 projecting upward, while the side surface 5b of the box 5 of the case main body 1 and thus the lower surface of the peripheral frame 6 downward A cylindrical leg 4 which is open and protrudes is provided. In the case of the present embodiment, the convex portion 2 and the cylindrical leg portion 4 are provided at the four corners of the case main body 1. Of course, the cylindrical legs 4 and the projections 2 are not limited to the case where they are provided at the four corners of the rectangular case main body 1, and are not limited to four pairs. For example, the cylindrical leg 4 and the convex portion 2 are respectively provided at the centers of the sides of the rectangular case main body 1 to form the cylindrical leg 4 and the convex at each vertex of the rhombus connecting the middle points of the sides of the rectangular. The portions 2 may be disposed, or four pairs of the cylindrical legs 4 and the projections 2 may be provided in two pairs with each corner of the case body 1 interposed therebetween.

  For example, as shown in FIG. 6, the convex portion 2 is formed of a steel cylinder and a dome, and is fixed to the upper surface of the peripheral frame 6 by, for example, welding. The dome at the tip is intended to function as a guide for facilitating the introduction when fitted with the recess 3 of the cylindrical leg 4. In the present embodiment, in order to facilitate alignment between the convex portion 2 and the cylindrical leg portion 4, the tip end of the convex portion 2 is a dome-shaped curved surface, but the present invention is not limited thereto. Or a conical top.

  On the other hand, the cylindrical leg portion 4 is fitted with the convex portion 2 of another storage box to prevent lateral displacement, and has a concave portion 3 fitted with the convex portion 2. Although the recessed part 3 is not limited to a specific shape or structure, it is preferable to be comprised at the front-end | tip of the cylindrical leg part 4 by the enlarged diameter part. The recess 3 (hereinafter also referred to simply as the enlarged diameter portion) constituted by the enlarged diameter portion has, for example, a tapered shape whose inner diameter is expanded toward the tip end opening and protrudes upward from the other case main body 1 It also serves as a guide for allowing the play in accommodating and fitting the convex portion 2 and for centering. In the case of this embodiment, for example, a concentric reducer used for piping having different diameters is used for the enlarged diameter portion 3 and fixed to the end of the straight pipe by welding or screwing. The enlarged diameter portion 3 is not particularly limited to the above-described concentric reducer, and may be, for example, a truncated conical tube that simply spreads in a conical shape. In any case, in the case of the tapered enlarged diameter portion 3 whose inner diameter is expanded toward the tip opening, the dome portion of the tip of the convex portion 2 is along or along the conical inner slope of the enlarged diameter portion 3 Rather, it enters relatively deep inside the enlarged diameter portion, but it abuts on the boundary portion with the straight pipe and is aligned approximately concentrically and placed on the convex portion 2. The enlarged diameter portion 3 may be a stepped pipe in which the hole diameter is gradually increased in some cases.

  Moreover, although not shown in figure, the cylindrical leg part 4 may be a mere straight pipe which does not have an enlarged diameter part. Also in this case, stacking operation is facilitated by providing a steeple-shaped slope or a shell-shaped spherical surface or the like at the top of the convex portion 2 with respect to the opening of the tip portion of the tube functioning as the concave portion 3 You can proceed to Furthermore, although the convex part 2 and the cylindrical leg part 4 are comprised by the combination of circular unevenness, it is not specifically limited to this, The combination of the pipe | tube of an angular cross section and a hole, or non-circles, such as elliptical shape A combination of asperities may be used.

  In the case of this embodiment, the cylindrical leg 4 protrudes downward at the four corners of the case body 1 from the bottom 5 a of the case body 1 and floats and supports the case body 1 when placed on a floor surface or the like. It is provided to function as a leg. Here, the cylindrical leg 4 does not have to receive and support the case body 1 directly. That is, in the present embodiment, the cylindrical leg 4 also serves as the leg for supporting the case main body 1, but it is not particularly limited to this, and it is used as a recess that fits with the protrusion 2 to prevent lateral displacement. It may only work. For example, the cylindrical leg 4 does not protrude below the bottom 5 a of the case main body 1 or does not protrude below the reinforcing member 9 even if it protrudes below the bottom 5 a of the case main body 1 , And may rise from the floor surface or the like. In this case, consideration is given to the length that can be reached and fitted to the cylindrical leg 4 of the case main body 1 of another storage box, in which the height of the convex portion 2 provided on the top surface of the case main body 1 is stacked up. There is a need to. Further, although not shown, the relationship between the convex portion 2 and the cylindrical leg portion 4 may be reversed, for example, the cylindrical leg portion 4 opened upward on the upper surface of the peripheral frame 6 The projections 2 projecting downward may be coaxially arranged on the surface or the surface facing the other storage box. In any case, by fitting the convex portion 2 and the cylindrical leg portion 4, as shown in FIG. 4, the storage place can be made compact by stacking in layers without causing lateral displacement.

  Further, the bottom of the case body 1 of the present embodiment is reinforced. For example, as shown in FIG. 2 and FIG. 3, reinforcement members 9 in an L shape in plan view are provided at the four corners of the bottom of the case main body 1 to surround the cylindrical legs 4. A space 10 for inserting a fork (fork) of the forklift is formed between the reinforcing members 9 and the reinforcing members 9 which are arranged equidistantly and at equal intervals. The reinforcing member 9 is welded to the bottom 5 a of the box 5 and also welded to the bottom of the hanging bracket 8 welded to the side 5 b of the box 5 of the case main body 1. And is provided to directly receive and support the box 5. It is preferable that the height of projection of the reinforcing member 9 from the bottom 5 a of the case body 1 is set so as to be the same height as the cylindrical leg 4. In this case, since the case body 1 is supported by the four cylindrical legs 4 and the four reinforcing members 9, the multi-point support is achieved and the distance between the support points is shortened, and the box / case is formed. Deflection of the main body 1 is further suppressed. Of course, the reinforcing member 9 may be floated without being grounded as a length shorter than the cylindrical leg 4 (the height from the bottom of the case main body 1 is lower). In the case of the present embodiment, the reinforcing members 9 are disposed at the four corners of the case main body 1, but the present invention is not particularly limited thereto, and the reinforcing members 9 may be provided at appropriate positions as needed. For example, a linear channel steel crossing the rectangular case main body 1 in the direction of the short side may be disposed to reinforce the bottom 5a of the case main body 1 and at the same time form a space 10 for inserting the fork of a forklift.

  A reinforcing plate 11 is also provided between the case body 1 and the cylindrical leg 4. The reinforcing plate 11 is disposed in each of two orthogonal directions of the case main body 1, that is, the long side direction and the short side direction, and the cylindrical leg portion 4 is reinforced so as not to be inclined with respect to the case main body 1 . The reinforcing plate 11 is fixed by welding to the peripheral frame 6 and the tubular leg 4 respectively.

  Furthermore, the case main body 1 is provided with a suspension fitting 8 for being lifted by a lifting means (not shown) such as a ceiling claim or a jib crane. For example, as shown in FIG. 5, FIG. 1, etc., the suspension fitting 8 is a plate welded and fixed to the outer surface 5b of the box 5 of the case main body 1 and the reinforcing member 9 of the bottom 5a. It is disposed so as to slightly project laterally and outwardly from the peripheral frame 6 of the main body 1. Further, the hanging metal fitting 8 is provided with a portion for hanging a wire or the like of the lifting and conveying means, for example, a hole 13 or a notch. In the case of the present embodiment, the hanging metal fittings 8 are provided at equal intervals from the middle point of the two opposing sides of the case body 1, for example, the long sides at equal intervals, in consideration of not losing balance when lifted. There is.

  According to the sheet storage box configured as described above, the sheets 30 are loaded from above into the box 5 of the case main body 1, stacked and accommodated flat. The storage box is placed alone on a floor or the like and is used for indoor or outdoor storage, but more intensive storage can be realized by stacking two or more stages. For example, as shown in FIG. 4, the case body 1 in which the desired number of sheets 30 are stacked and stored may be stacked and stored in any number of stages.

  The storage boxes are stacked, for example, by lifting and conveying means such as ceiling claims or by a forklift, and transported to a desired storage position, and stacked while fitting the convex portion 2 and the concave portion 3 of the cylindrical leg portion 4 It will be. In the case of the present embodiment, the cylindrical leg 4 which protrudes toward the lower part of the other case main body 1 stacked from above is provided on the convex part 2 which protrudes upward from the case main body 1 of the storage box placed below. Stack while aligning and fitting. After stacking, the upper and lower storage boxes are engaged in the horizontal direction by the engagement of the convex portion 2 and the cylindrical leg portion 4 so that they are shifted or fitted to each other even in the event of an earthquake rolling or some pitching. It is possible to prevent the collapse of the storage box without losing the fit.

  On the other hand, when the sheets 30 are used, the stacked storage boxes are separated, and the sheets 30 stored in the box are taken out as needed. For example, the stacked storage box is lifted from the upper stage by a lifting conveyance means or a forklift, etc. to release the fit between the convex portion 2 and the cylindrical leg portion 4 and then horizontally moved, and then the target site or other storage Transport to the place.

  7 to 10 show another embodiment of the sheet storage box according to the present invention. The storage box according to this embodiment can be changed to a case and a carriage as required.

Here, the cylindrical leg 4 protrudes downward below the bottom of the case body 1 at an arbitrary position of the case body 1, for example, at four corners, and floats and supports the case body 1 when placed on a floor surface or the like. Although it doubles as a leg, it is not particularly limited thereto. The cylindrical leg portion 4 does not protrude below the bottom 5 a of the case body 1 as long as the wheel can lift and support the case body 1 when the caster 17 is attached. Even if it protrudes below the bottom 5 a of 1, it does not project below the reinforcing member 9 but may be configured to float from a floor surface or the like. In this case, it is necessary to consider the length that can be reached and fitted to the cylindrical leg 4 of the other case main body 1 on which the height of the convex portion 2 provided on the top surface of the case main body 1 is stacked. It goes without saying that there is one.

  The shape and the like of the handle 22 is not limited to a specific shape, but the shape of the handle 22 shown in FIG. 10 is general as a handle of a truck. The shape, structure, and the like of the handle 22 are not particularly limited to those shown in the drawings, but it is natural that ones that can be pressed by a light force are preferred. In the case of this embodiment, at both lower ends of the gate-shaped handle 22, there is provided a shaft portion 23 which is inserted into the hole 14 of the peripheral frame 6 of the storage box, and the shaft portion 23 is inserted into the hole 14 It can be easily installed and removed.

  According to the combination of the sheet storage box, the caster, and the handle configured as described above, when it is necessary to move the storage box main body at the time of tidying up or separating the sheets 30, the caster 17 and the handle as required. The carriage 22 is attached to the case main body 1 and can be easily carried by human power. When the sheets 30 are stored, the casters 17 and the handle 22 are removed from the storage box / case body 1 and stacked.

  That is, when the sheets 30 are used, the stacked storage boxes are separated and the sheets 30 stored in the box are taken out as needed. For example, one storage box is lifted from the top by an overhead crane or a forklift and temporarily placed in an appropriate place, and the caster 17 is attached to the cylindrical leg 4 and the handle 22 is attached to the case main body 1 Let For example, in the case of a storage box in which 50 sheets of flexible vinyl chloride having a thickness of 2 mm, a length of 1820 mm, and a width of 1000 mm are stacked and stored, the weight of sheets 30 (approximately 300 kg) even if the steel storage box weighs approximately 100 kg. In addition to the above, the total weight can be reduced to about 400 kg, so that the caster 17 and the handle 22 can be attached to make it a bogie and it can also be transported by human power.

  On the other hand, when stacking storage boxes, the casters 17 and the handle 22 are removed. And it is piled up by fitting the convex part 2 of the storage box of the lower stage to the enlarged diameter part 3 of the cylindrical leg part 4. As shown in FIG.

  The above-described embodiment is an example of the preferred embodiment of the present invention, but is not limited to this, and various modifications can be made without departing from the scope of the present invention. For example, in this embodiment, although the example of the soft polyvinyl chloride sheet used for curing of a floor was mentioned and explained, it is not restricted in particular in this. It goes without saying that it can also be used for the storage of flexible sheets 30, which are also used for other applications, for example. Further, the material of the sheets 30 is not limited to the soft resin, and for example, it is suitable for storage of flexible plywood such as thin veneer.

  Moreover, in the above-mentioned embodiment, although the convex part 2 and the cylindrical leg part 4 are formed as a separate member, and are each welded by the surrounding frame 6 which protrudes in a horizontal direction from the box 5, they are shape | molded as one part It may be made to weld directly on the side 5b of the box 5. That is, in the case of the case main body 1 (only the box 5) without the peripheral frame 6, the convex portion 2 and the tubular leg 4 are directly attached to the case main body 1 to support the case main body 1. At this time, a portion above the upper portion of the cylindrical leg portion 4, that is, the top surface of the case body 1 (in the case of this embodiment, the upper edge of the box 6) is a convex portion 2, and the portion below it As the tubular leg 4.

  Furthermore, the storage box according to the present embodiment can also be used as a case in the process of distributing sheets. That is, it is possible to package and distribute in a state where the number of sheets of sales unit is stored in the storage box.
