Further, each face plate is not limited to having a constant height. In the storage case 4 shown in FIG. 5, the rear end of the first side plate 37 is extended, and the extension portion 37a is bent inward to form a part of the rear surface plate. As described above, a low back plate is preferable in order to suppress bulk during stacking, but a high back plate is preferable as a method for increasing the case strength. The strength of the storage case 4 is increased by raising a part of the rear surface plate. Further, the front plate 38 is set at the same height as the second side plate 32.
(Other forms)
The storage case 3 of FIG. 3 has a protruding portion 40 that locks to a shelf stile at the rear upper end portion of the first side plate 31. The protruding portion 40 corresponds to the rear protruding portion of the present invention, and has a function of preventing the shelf on which the storage case is placed from falling forward. The same effect can be obtained when the rear protruding portion of the present invention is provided not only at the rear upper end portion of the first side surface plate but also at the upper end portion of the rear surface plate. When the rear protruding portion is provided on the rear surface plate, the upper end of the rear protruding portion should be higher than the first side surface portion.

Further, when the rack without the back plate is installed away from the wall, the front protruding portion may be provided at the front upper end of the first side plate or the upper end of the front plate so that the storage case does not get into the back of the shelf. .. With respect to the front protruding portion, a stopper is provided on the lower front side of the upper shelf on which the storage case is placed so that the front protruding portion abuts. The storage case 6 of FIG. 12 is provided with a front protruding portion 46 at the front upper end of the first side plate 45. Similar to the rear protruding portion 40 of the storage case 3, the front protruding portion 46 extends the first side surface plate 45 upward, and provides a horizontal slit at the base of the extended portion to separate it from the first side surface plate. , The separated part is bent. Although the storage case 6 of the illustrated example includes both the front protruding portion 46 and the rear protruding portion 40, a storage case having only the front protruding portion 46 is also included in the present invention.

There are no restrictions on the material or manufacturing method of the storage case of the present invention. Examples of materials other than metal include resin, hard pulp, and corrugated cardboard. If it is made of resin, a transparent storage case can be produced, and the stored items can be identified from any surface of the case.
[Sort storage rack]
The sorting storage rack 5 of FIG. 6 includes a rack 50 and a plurality of storage cases 3.

The rack 50 includes four columns 51 arranged at four corners and a plurality of shelves 60 bridged between the columns 51. The shelf support bracket can be attached to the support column 51 at an arbitrary height, and the shelf 60 can be bridged to a desired height. In the illustrated example, eight shelves 60 are attached, and the shelf 60 at the uppermost position substantially functions as a ceiling plate, and a storage space of seven stages is formed.

In the shelf 60, four sides around the front, back, left, and right of a rectangular metal plate are bent downward, and stiles are formed on the front, back, left, and right edges of the mounting surface portion 61. FIG. 8 shows a front stile 62 that is bent downward from the front edge of the mounting surface portion 61, further bent rearward, and further bent upward at the tip portion. That is, the front stile 62 is formed by sequentially bending a front lowering portion 62a following the mounting surface portion 61, a bottom portion 62b parallel to the mounting surface portion 61, and a tip portion 62c parallel to the front lowering portion 62a. 62c corresponds to the stopper in the present invention.

A plurality of storage cases 3 are arranged on the shelf 60 without any gap. FIG. 6 shows an example in which the storage case 3 is placed on the lower four shelves 60. The dimension between the mounting surface portion 61 of the shelf 60 and the lower end of the front stile 62 of the upper shelf 60 is slightly larger than the height H1 of the first side plate 31 of the storage case 3, and the protruding portion 40 It is smaller than the total height H including. As an example of the dimensions of the storage case 3, the bottom plate 10 has a width: 290 mm × a depth: 500 mm, a height H1: 265 mm of the first side plate 31, a total height H: 280 mm of the first side plate 31, and a second side plate 32. Height H2: 50 mm can be exemplified. The tip portion 62c functions as a stopper for the storage case 3 having this dimension because the height of the space between the shelves 60 is larger than the height H1: 265 mm of the first side plate 31 and the total height H: 280 mm. Is also small. Further, the height H1 of the first side plate 31 is preferably close to the height of the space between the shelves 60 in order to prevent products from being mixed.

Although FIG. 6 shows an example in which the storage case 3 is placed on the lower four shelves 60, the storage case 3 can be placed on any shelf. Further, although FIG. 6 shows an example in which the storage cases 3 having the same dimensions are used, a plurality of types of storage cases having different frontage dimensions can be mixed.

As shown in FIG. 7, when putting in and taking out an article in the storage case 3, put a hand on the pull tab 15 and pull out the case toward you. The storage case 3 is smoothly pulled out using the second side plate 32 of the storage case 3 on the left side and the first side plate 31 of the storage case 3 on the right side as guides. In the pulled-out storage case 3, the locking portion 43 of the protruding portion 40 of the first side plate 31 hits the tip portion 62c of the front stile 62 of the shelf 60, and the tip portion 62c functions as a stopper to prevent further withdrawal. (See FIG. 8), the storage case 3 can be prevented from falling from the front of the shelf 60.

Articles are taken in and out of the storage case 3 pulled out from the second side plate 32 side. By pulling out the storage case toward you, you can see the inside of the case to the back, and since the second side plate 32 is lower than the first side plate 31, you can easily put in and take out articles. In the case where the left and right side plates are the same height, the difficulty of putting in and out is the same regardless of which side is taken in and out, and if both left and right are lowered, it is easy to put in and out, but the storage of tall items becomes unstable, and the left and right sides become unstable. If both are raised, it will be difficult to put them in and out. In the storage case of the present invention, the second side plate is made lower than the first side plate, so that the articles can be stably stored and taken in and out easily.

Further, if a label 39 or an IC tag printed with identification information of the stored article is attached to the second side surface plate 32, the article can be quickly confirmed at the time of taking in and out. The second side plate 32 is rubbed because it serves as a slide guide for the storage case 3 adjacent to the right side, but the label 39 can be prevented from being peeled off or worn by forming a dent in the portion where the label 39 is attached. Further, if the inside of the storage case 3 is divided into a plurality of rooms in the depth direction by a movable partition 100 or the like, articles of different varieties can be stored and sorted in the depth direction as well. When dividing into a plurality of rooms, if a plurality of label recesses are formed in the depth direction of the second side plate 32, the label 39 corresponding to the article in each room can be attached.

In the storage case 3, a part of the protruding portion 40 is bent to form a locking portion 43 parallel to the front stile 62, thereby expanding the contact area with the front stile 62. By expanding the contact area between the two in this way, the fall prevention effect of the storage case 3 is enhanced. However, the present invention is not limited to the case where the protruding portion is provided with a portion parallel to the front frame of the shelf. Although the storage case 3 in the illustrated example is a bent product of a metal plate, it is possible to prevent the storage case from falling even when the protruding portion 40 is brought into contact with the front stile 62 by the edge surface of the metal plate without bending. ..

The above-mentioned sorting storage rack 5 uses the tip portion 62c of the front stile 62 of the shelf 60 as a stopper. The stopper in the present invention is required to be at a position higher than the first side plate 31 of the storage case 3, allow the first side plate 31 to pass through, and be provided at a height that abuts on the protrusion 40. Is. However, when the storage case 3 is pulled out toward the front, if there is something that interferes with the protrusion 40 of the first side plate 31 before it reaches the stopper, it is necessary to change the position of the stopper.

The shelf 70 of FIG. 9 has the same structure as the shelf 60 of FIG. 8 with the mounting surface portion 61 and the front stile 62, and a reinforcing material 71 having the same height as the front stile 62 protrudes from the back surface of the mounting surface portion 61. It is attached in such a manner that In the shelf 70, the storage case 3 cannot be sufficiently pulled out by hitting the reinforcing material 71 before the protruding portion 40 of the storage case 3 reaches the front stile 62. For such a shelf 70, the storage case 3 can be pulled out to the position of the front stile 62 by separately attaching a stopper 80 to the front stile 62. The stopper 80 is a bending of a metal plate in which a backing plate 81a that comes into contact with the protruding portion 40 of the storage case 3 and a mounting plate 81b for attaching to the front stile 62 are integrated via an inverted V-shaped bent portion 81c. It is a processed product, and when the backing plate 81a is screwed along the outer surface of the tip portion 62c of the front stile 62 and the mounting plate 81b is screwed to the inner surface of the bottom portion 62b of the front stile 62, the backing plate 81a is along the tip portion 62a. The tip of the reinforcing member 71 is lower than the lower end of the reinforcing member 71. With respect to the shelf 70 to which the stopper 80 is attached, the height H1 of the first side surface plate 31 is set lower than the lower end of the backing plate 81a of the stopper 80, and the protruding portion 40 is lower than the reinforcing member 71 and the backing plate. A storage case 3 set at a height that abuts on 81a is used.

In the shelf 90 of FIG. 10, the front lowering portion 92a of the front stile 92 is extended longer than the front stile 62 of FIGS. 8 and 9, and the tip reaches a position lower than the reinforcing member 71, and the tip portion following the bottom surface portion 92b. The 92c functions as a stopper. With respect to the shelf 90, a storage case in which the first side plate 31 is set to a height lower than the lower end of the front stile 92 and the protruding portion 40 is set to a height that abuts the tip portion 92c of the front stile 92. 3 is used.

In the present invention, the presence or absence of protrusions at the front and rear of the storage case is arbitrary. Even in a storage case that does not have a fall prevention function, it is possible to enjoy the effect that articles can be easily taken in and out from the second side plate side. Further, the storage case is not limited to a large-scale rack such as an article picking facility. It can also be used as a bookshelf or cabinet in a house or office.
[Picking method]
FIG. 11 shows a picking method using the sorting storage rack 5 of FIG. This figure is an example in which two sorting storage racks 5 are connected and installed.

The operator pulls out the target storage case 3 and takes out the article toward the second side plate 32. Therefore, the storage area is easily accessible, and the article in the back of the storage case 3 can be easily taken out. Further, in the case where the face plates on the four sides are equal, the stored items cannot be grasped without looking into the case from above, but in the storage case 3 of the present invention, it can be grasped even from the side of the lowered second side plate 32. The storage case 3 can be arranged up to the height position. As a result, more storage cases 3 can be arranged in the same space than in the past, and picking work can be efficiently performed with a small number of work flow lines.

The sorting storage rack 5 in the illustrated example is a combination of a storage case 3 having a (rear) protruding portion 40 and a rack 50 having a stopper, and the presence / absence of the rear protruding portion and the presence / absence of the stopper in the storage case are the front of the storage case. Only relevant for fall prevention. As long as the storage case of the present invention in which the second side plate is lower than the first side plate is used, it is possible to improve the efficiency of the above-mentioned large number of storage cases and the picking work regardless of the presence or absence of the rear protrusion and the stopper. ..

Further, with respect to the storage case 6 of FIG. 12, a stopper is provided on the upper front side of the rack, that is, the lower front side of the upper shelf on which the storage case 6 is placed, and the front protruding portion 46 is brought into contact with the storage case 6. As a result, it is possible to prevent the storage cases 6 from getting into the back and to align the positions of the plurality of storage cases 6 arranged side by side in the depth direction. As with the rear protruding portion described above, it is possible to arrange a large number of storage cases and improve the efficiency of picking work regardless of the presence or absence of the front protruding portion and the stopper.
