Description

[Technical Field]

[0001] The present invention relates to a storage case that can be detachably attached to a steel shelf. [Background technology]

[0002] A wafer has multiple devices such as ICs and LSIs formed on its surface, separated by planned dividing lines. The back side of the wafer is ground using a grinding machine to form it to the desired thickness, and then the wafer is divided into individual device chips using a dicing machine and laser processing machine. These chips are then used in electrical devices such as mobile phones and personal computers.

[0003] A grinding apparatus is composed of a chuck table that holds wafers, grinding means equipped with a grinding wheel that grinds the wafers held on the chuck table, a mounting table that holds a cassette containing multiple wafers, unloading means that transports wafers from the cassette, a temporary holding table that centers the transported wafers, load means that transports wafers from the temporary holding table to the chuck table, cleaning means that cleans the ground wafers, transport means that transport the ground wafers from the chuck table to the cleaning means, and many other parts including bolts, nuts, wires, tubes, etc. (See, for example, Patent Document 1.) Dicing apparatuses and laser processing apparatuses are also similarly composed of many parts. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2023-102926 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the assembly process for assembling the above-mentioned processing equipment, many of the parts that make up the processing equipment are supplied along with invoices. However, if the method for managing the invoices used to manage the supplied parts on the shelves where the parts are stored is not appropriate, the parts and invoices will not match, which can lead to confusion.

[0006] The present invention has been made in consideration of the above facts, and its main technical objective is to provide a storage case that can solve the problem that occurs when the parts supplied in the assembly process do not match the invoices, causing confusion when the invoice management method is not appropriate on the shelves where the parts are stored. [Means for solving the problem]

[0007] In order to solve the above-mentioned main technical problem, according to the present invention, there is provided a storage case that is detachably attached to a steel shelf, and that comprises a pair of side walls positioned at a distance from each other, and a bottom plate that is supported by supports formed at the lower part of the side walls, and that has fixing means formed at the upper part of the side walls that are detachably fixed to one beam that constitutes the steel shelf and the other beam that faces the one beam at a distance from the one beam, and that has two external fixing parts positioned on the outside of the one beam and the other beam, and two internal fixing parts positioned on the inside of the one beam and the other beam, and that clamps and fixes the beam between the external magnets arranged in the external fixing parts and the internal magnets arranged in the internal fixing parts.

[0008] Preferably, a rail is formed on the upper portion of the side wall to adjust the position and spacing between the outer and inner fixed parts, so as to accommodate the spacing between the one beam and the other beam and the thickness of the beam. Also, it is preferable that the rail has fine projections and recesses formed in the longitudinal direction, and the outer and inner fixed parts have projections and recesses that engage with the projections and recesses. [Effects of the Invention]

[0009] The storage case of the present invention is a storage case that can be attached and detached to a steel shelf, and comprises a pair of side walls positioned at a distance from each other, and a bottom plate supported by supports formed on the lower part of the side walls. The upper part of the side walls is formed with fixing means that can be detachably fixed to one beam that makes up the steel shelf and the other beam that faces the one beam at a distance from the one beam. The fixing means has two external fixing parts positioned on the outside of the one beam and the other beam, and two internal fixing parts positioned on the inside of the one beam and the other beam. Since the beams are sandwiched and fixed by the external magnets arranged in the external fixing parts and the internal magnets arranged in the internal fixing parts, it is possible to attach the case by changing the distance between the external fixing parts and the corresponding internal fixing parts, even if the thickness of the pair of beams provided on the steel shelf or the distance between the pair of beams changes. Since the case can be attached and detached to the steel shelf, the installation position on the steel shelf can also be selected freely. As a result, for example, if this system is used on a steel shelf installed in an assembly process where processing equipment is assembled, when many parts are supplied together with invoices, the invoices can be stored directly above the position where the items are stored, eliminating the problem of parts and invoices not matching and causing confusion.

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a storage case configured based on the present invention will be described in detail with reference to the accompanying drawings.

[0012] 1 shows a perspective view of a steel shelf 2 (only a portion is shown) on which a storage case 30 of this embodiment is mounted. The steel shelf 2 includes support posts 22, 22 that form the four corners (the support post 22 on the opposite side is omitted), a shelf board 24 supported by the support posts 22, 22, and a pair of beams 26a, 26b that form the shelf 2. The pair of beams 26a, 26b are disposed on the underside of the shelf board 24. The shelf board 24 is supported by shelf support members (not shown) that are attached to the support posts 22, and the height position of the shelf support members can be changed to change the height position of the shelf board 24.

[0013] One beam 26a and the other beam 26b constituting the pair of beams are arranged along the longitudinal direction on the underside of the shelf board 24, and are arranged to face each other at a certain distance. In the steel shelf 2 of this embodiment, it is not necessary for all components to be made of steel, as long as at least the pair of beams 26a, 26b are made of steel. For example, the surface of the shelf board 24 may be made of wood.

[0014] The storage case 30 is detachably attached to the steel shelf 2 described above, and can store items, including slips, in the direction indicated by arrow R1 from the area open on the front side. The storage case 30 of this embodiment will be described in detail with reference to Fig. 1, Fig. 2, which shows the storage case 30 in a disassembled state, and Fig. 3, which shows the storage case 30 fixed via the pair of beams 26a, 26b described above. For ease of explanation, Fig. 3 omits all components other than the pair of beams 26a, 26b (shown by dashed lines).

[0015] As shown in Figures 2 and 3, the storage case 30 includes a pair of side walls 32a, 32b positioned with a gap between them, support portions 33a, 33b formed on the lower inner surfaces of the side walls 32a, 32b, and a bottom plate 35 supported by the pair of support portions 33a, 33b. The support portions 33a, 33b are formed with engagement holes 332 that engage with protrusions 352 formed on the underside of the bottom plate 35. Although the shape of the support portion 33a on the near side in Figure 2 is not visible, it has the same configuration as the support portion 33b disposed opposite it. The dimensions of the bottom plate 35 can be set arbitrarily and can be determined according to the dimensions of the items, including slips, to be stored in the storage case 30.

[0016] Fixing means 40, 40 are attached to the upper portions of the side walls 32a, 32b, and are detachably fixed to one beam 26a constituting the steel shelf 2 and the other beam 26b facing the one beam 26a at a distance.

[0017] The fixing means 40 includes two external fixing portions 322a, 322b positioned on the outside of one beam 26a and the other beam 26b, and two internal fixing portions 324a, 324b positioned on the inside of the one beam 26a and the other beam 26b.

[0018] In the outer fixed portions 322a, 322b, outer magnets 34, 34 are disposed on the surfaces facing the outside of the one beam 26a and the other beam 26b. The outer magnets 34, 34 are preferably strong magnets, such as neodymium magnets. In addition, in the inner fixed portions 324a, 324b, inner magnets 36, 36 are disposed on the surfaces facing the inside of the one beam 26a and the other beam 26b.

[0019] Rails 328 are formed on the upper portions of the side walls 32a, 32b to adjust the positions and spacing between the outer fixed portions 322a, 322b and the inner fixed portions 324a, 324b. In this embodiment, the outer fixed portion 322a is fixed to one end of the side walls 32a, 32b, and the other outer fixed portion 322b and the inner fixed portions 324a, 324b are configured to be movable in the longitudinal direction along the rails 328.

[0020] As can be seen from FIG. 2, the rail 328 has a rail groove 326a that opens to the upper surface along the longitudinal direction of the side walls 32a, 32b, and the bottom 326b of the rail groove 326a is formed wider than the opening width of the rail groove 326a that opens to the upper surface.

[0021] The other outer fixed part 322b has an attraction part 323a in which the above-mentioned outer magnet 34 is disposed, and an engagement part 323b disposed below the attraction part 323a and engaging with the rail groove 326a and bottom part 326b. The engagement part 323b has a narrow width portion corresponding to the above-mentioned rail groove 326a and a wide width portion corresponding to the bottom part 326b of the rail groove 326a. The one inner fixed part 324a disposed opposite the one outer fixed part 322a has an attraction part 325a in which the internal magnet 36 is disposed, and an engagement part 325b disposed below the attraction part 325a and engaging with the rail groove 326a and bottom part 326b. The engagement part 325b has a narrow width portion corresponding to the above-mentioned rail groove 326a and a wide width portion corresponding to the bottom part 326b of the rail groove 326a. The other inner fixed part 324b, which is arranged so as to face the other outer fixed part 322b, includes an attraction part 325a on which the internal magnet 36 is arranged, and an engagement part 325b which is arranged below the attraction part 325a and engages with the rail groove 326a. Note that the outer fixed part 322b, the inner fixed part 324a, and the inner fixed part 324b in this embodiment are made of the same member.

[0022] The engaging portion 323b of the other outer fixed portion 322b, the engaging portion 325b of the inner fixed portion 324a, and the engaging portion 325b of the inner fixed portion 324b are inserted from the opening of the rail groove 326a of the side walls 32a and 32b on the near side in the figure, and in the illustrated embodiment, are inserted in the order of one inner fixed portion 324a, the other inner fixed portion 324b, and the other outer fixed portion 322b, in the orientation shown in Figures 2 and 3. The rail groove 326a and bottom portion 326b are formed with a large size and shape that includes a certain amount of play compared to the dimensions of the engaging portions 323b, 325b, and 325b, and can be freely moved along the longitudinal direction of the rail 328 that constitutes the side walls 32a and 32b.

[0023] When mounting the storage case 30 equipped with the above-mentioned fixing means 40, 40 on a pair of beams 26a, 26b of the shelf 2, one inner fixing portion 324a, the other inner fixing portion 324b, and the other outer fixing portion 322b are mounted on the rails 328 of the side walls 32a, 32b at a certain interval, and then, as shown in Figure 3, the outer fixing portion 322a formed on one side wall 32a and one outer fixing portion 322a formed on the other side wall 32b are positioned on the outer surface of one beam 26a, and the outer magnets 34, 34 of the outer fixing portions 322a, 322a are attracted to the outer surface of the one beam 26a. Next, one inner fixed part 324a, the other inner fixed part 324b, and the other outer fixed part 322a are moved appropriately along the rails 328, so that the one beam 26a is sandwiched and attracted between the outer magnet 34 of the one outer fixed part 322a and the inner magnet 36 of the one inner fixed part 324a, and the other beam 26b is sandwiched and attracted between the outer magnet 34 of the other outer fixed part 322b and the inner magnet 36 of the other inner fixed part 324b. This fixes the accommodation case 30 to the pair of beams 26a, 26b.

[0024] According to the above-described embodiment, even if the thickness of the pair of beams 26a, 26b provided on the steel shelf 2 or the spacing between the pair of beams 26a, 26b changes, as long as it falls within the longitudinal dimension of the side walls 32a, 32b, it is possible to change and mount the storage case 30 between the outer fixed portions 322a, 322b and the corresponding inner fixed portions 324a, 324b, and since the storage case 30 can be used detachably with respect to the shelf 2, it is possible to select the installation position on the shelf 2 as desired, and it is possible to position and mount the storage case 30 of this embodiment directly above (or directly below) the parts to be placed on the shelf 2. As a result, when many parts are supplied together with invoices to an assembly process for assembling a processing device, it is possible to store the invoices directly above the position where the articles are to be stored, eliminating the problem of parts and invoices not matching and causing confusion.

[0025] Furthermore, the storage case 30 of this embodiment is highly versatile because the spacing between the pair of side walls 32a, 32b can be adjusted to match the dimensions of the bottom plate 35, and the shape of the storage case 30 can be changed as desired.The items stored are not limited to the above-mentioned slips, and the case can also be used as a toolbox or a place to store small items (ballpoint pens, measuring tapes, etc.).

[0026] Furthermore, in the storage case 30 of this embodiment, fine irregularities 328a are formed on the upper surfaces of the side walls 32a and 32b along the rail groove 326a of the rail 328 in a direction perpendicular to the longitudinal direction of the side walls 32a and 32b. Furthermore, fine irregularities that engage with the above-mentioned irregularities 328a are formed on the lower surfaces of the suction portions of the outer fixed portion 322b, the inner fixed portion 324a, and the inner fixed portion 324b that engage with the rail groove 326a of the rail 328. The functions and actions of the irregularities 328a formed on the upper surface of the side wall 32a and the irregularities 325c formed on the lower surface of the suction portion 325a of the inner fixed portion 324a that faces the one outer fixed portion 322a across one beam 26a will be described with reference to FIG.

[0027] As shown in FIG. 4, the outer magnet 34 of one of the outer fixed parts 322a is attracted to the outer surface 27a of one of the beams 26a, and the inner magnet 36 disposed on the attracting part 325a of the inner fixed part 324a is attracted to the inner surface 27b of the one of the beams 26a. As a result, the one of the beams 26a is sandwiched between the outer magnet 34 and the inner magnet 36, and one corner of the housing case 30 is fixed. At this time, the unevenness 328a formed on the upper surface of the side wall 32a engages with the unevenness 325c formed on the lower surface of the attracting part 325a of the inner fixed part 324a. As a result, movement of the inner fixed part 324a is restricted, and fixation by the outer fixed part 322a and the inner fixed part 324a is appropriately maintained. Furthermore, one of the beams 26a shown in the figure has a trapezoidal shape in which the inner surface 27b is inclined relative to the outer surface 27a, but as described above, the rail groove 326a and bottom 326b formed in the side wall 32a are formed with large dimensions that allow play relative to the engagement portion 325b that forms the internal fixing portion 324a, so that the suction portion 325a of the internal fixing portion 324a can be inclined to fit along the inner surface 27b of the one beam 26a, and the unevenness 325c formed on the lower surface of the suction portion 325a of the internal fixing portion 324a engages with the unevenness 328a formed on the upper surface of the side wall 32a, thereby more reliably restricting the movement of the internal fixing portion 324a in the longitudinal direction, and the fixation by the external fixing portion 322a and the internal fixing portion 324a is properly maintained. The unevenness 325c formed on the underside of the suction portion 325a shown in FIG. 4 is similarly formed on the underside of each suction portion of the outer fixed portion 322b and the inner fixed portion 324b, and the same effect as described above can be obtained.

[0028] In the embodiment described above, one external fixed portion 322a facing the outside of one beam 26a is formed on one end of the side walls 32a, 32b, and its position and orientation are fixed, but the present invention is not limited to this. For example, the external fixed portion facing the outside of one beam 26a may be configured similarly to the other external fixed portion 322b described above, and may be movable along the rails 328 of the side walls 32a, 32b. This makes it possible to accommodate cases where the outer surface 27a of one beam 26a is inclined, for example, and improves the degree of freedom in mounting on the shelf 2.

[0029] Furthermore, in the above embodiment, a storage case based on the present invention is described as being used on a steel shelf 2 installed in the assembly process of processing equipment, but the storage case of the present invention is not limited to being used on a steel shelf installed in the assembly process of processing equipment, and can be applied to any steel shelf that requires a storage case configured based on the present invention, and may, for example, be used on a steel shelf installed in a warehouse for storing goods.
