Is a cross-sectional explanatory view of the same side, FIG. 3 is an external perspective view of a shelf portion, FIG. 4 is a plan view of a storage unit, and FIGS. 5A and 5B are AA sectional views and BB sectional views in FIG. 4, respectively. 6 and 6 are external perspective views of the article support member, in which (a) is a single product,
(B) shows a connected state. Further, FIG. 7 is an operation explanatory view of the article standing means in the article support member, and FIG. 8 is an operation explanatory view of the detection means.

First, the article to be stored is, for example, a solid article having a shape having an upright state, that is, a shape that also exhibits a fallen state, and is shown as an ampoule container for medicines in the drawings. Other specific examples of the "solid article having a shape having an upright state" include cylindrical bottles and cans. Of course, in the present invention, the articles are not limited to these container-shaped ones.

1 and 2, the storage rack device 1 is
Shelf portion 2 for storing articles S in a row in the front-rear direction
And a housing 3 that houses the shelf 2. The "front-back direction" means the front-back direction of the paper surface in FIG. Case 3
Is a member having a vertically long rectangular parallelepiped shape made of a resin plate, a stainless plate, or the like, the front side of which is formed with an opening, and a caster 3a for moving and an adjuster 3b for fixed installation are attached to the bottom. Has been.

The storage rack device 1 shown in the figure comprises a plurality of racks 2 (five in the figure) which are the components of the present invention. A drawer portion 4 capable of accommodating a comparatively large medicine bottle or the like is provided at the bottom of the housing 3.
The drawer portion 4 does not have a biasing means or the like described later.

Each of the shelves 2 is constructed horizontally and can be pulled out to the front side, and a handle 5 is formed on each front surface as shown in FIG. By providing the shelves 2 horizontally, the number of articles S to be stored increases and the storage efficiency improves.
FIG. 2 shows a state in which the fourth and fifth shelves 2 from the top are pulled out. As will be described later in detail, the fourth-stage shelf 2 is regulated by the regulation means so that it cannot be pulled out any further. With respect to the fourth-stage shelf 2, a loading / unloading port 6 for the article S is provided at the front upper portion thereof. Is formed. The shelf 2 on the fifth stage shows the state in which the restricting means is released and further pulled out. This will also be described in detail later.

As shown in FIG. 3, the shelf 2 of the present embodiment.
Is a rectangular frame 7 with a handle 5 on the front,
It has a structure in which the storage unit 8 is incorporated. Although a fixing method when assembled is not particularly shown, a known fitting means or the like is used. The storage unit 8 includes an item S (see FIG.
(Not shown) so that it can be stored in multiple rows,
It has a plurality of partition plates 9 extending in the front-rear direction. The front end side of the partition plate 9, that is, the upper portion on the side facing the loading / unloading port 6, is subjected to corner-cutting processing such as curved surface formation so that fingers do not interfere with the loading / unloading of the article S. Each partition plate 9 is vertically installed on a bottom plate 10 (see FIG. 4) having a rectangular shape in plan view.

In the case where articles S of different sizes are stored in each row in the shelf 2 in a certain level, FIG.
As shown in FIG. 6, if the storage units 8 are provided separately, for example, one storage unit 8 has a smaller mounting pitch between the partition plates 9 for storing a small ampoule container, and another storage unit 8 has a smaller mounting pitch. By increasing the pitch for storing a large ampoule container, it is possible to easily deal with it. In this way, by providing the storage units 8 in a divided manner and incorporating them into the frame 7, it is possible to construct an economical storage rack device and easily accommodate variations in the stored articles.

In the storage unit 8, between the adjacent partition plates 9, that is, in each storage passage in which the articles S are stored in a row, the entire articles in a row are inserted through the articles S located at the rearmost end of the row. A biasing means 11 is provided for biasing the above toward the above-mentioned inlet / outlet port 6 side. Since the shelf 2 is provided in a horizontal shape, it is difficult to apply a weight using gravity as the biasing means 11. Therefore, a configuration using an elastic member, such as a coil spring, is also conceivable, but in the present embodiment, a spring main body (spiral spring) 12 is used as the biasing means 11 as shown in FIG. .

When the articles S arranged in rows are always biased with the same force even when the number of stored articles S is full or when the number of articles S stored is small, the loading / unloading port 6 is provided when the number of stored articles S is small. When the article S is taken out from, the frictional force with the bottom plate 10 with respect to the rest of the stored articles S is small, and thus the impact at the time of movement due to the urging force is likely to be large. Therefore, when the article S is easily damaged, for example, in the case of an ampoule container formed from thin glass, it is necessary to pay sufficient attention to the design of the biasing means 11, especially the set value of the biasing force. On the other hand, the urging force changes according to the number of stored items so that the urging force is large when the number of stored items S is large and the urging force is small when the number of stored items is small. With this configuration, the balance between the frictional force generated between the entire stored articles S and the bottom plate 10 and the urging force is always maintained. Therefore, even when the number of stored articles is small, The fragile article S can be stored and slid more safely, and the urging means 11 can be easily designed.

In the case of a Conston type spring, the biasing force of the spring is always constant, so that it is difficult to apply it to the structure. The urging force is small, and the urging force is large when the winding distance of the spring is long, that is, the urging force changes in accordance with the winding amount of the spring, so that the application to the above configuration is extremely easy. The mainspring 12 has a known structure in which a steel strip is formed in a spiral shape, for example.

Explaining an example of mounting the mainspring spring 12, first, a case 13 having a rectangular parallelepiped shape containing the mainspring spring 12 is arranged in the storage passage of the article S. A bracket 14 is attached to the case 13, and the bracket 1
By engaging the protrusion 14a formed in 4 with the guide groove 9a formed in the side surface of the partition plate 9 along the front-rear direction, the case 13 is guided in the guide groove 9a in the front-rear direction. It is movably installed. The case 13 corresponds to the "biasing force transmitting member" recited in the claims.

As shown in FIG. 5 (a), a drawer port 13a is formed in the lower part of the front surface of the case 13. In the case 13, a thread winding reel 15a for accommodating a thread member 15 made of a resin material in a wound state is rotatably accommodated, and the mainspring 12 has one end side in the hollow inside of the reel 15a. It is accommodated as a mode in which it is connected to the central fixed shaft 13b fixed to the side and the other end side is connected to the inner peripheral surface portion of the reel 15a. The filamentous member 1 pulled out from the outlet 13a
5 has a slot 10a formed in the bottom plate 10 (see FIG. 4).
Etc.), and is engaged with a front portion of the shelf 2, that is, a protrusion 10b formed at the front end of the bottom plate 10 in the present embodiment. Of course, the member pulled out from the outlet 13a is not limited to the thread member 15 made of a resin material or the like,
Any strip-shaped member having a function of winding the mainspring 12 may be used.

As described above, the mainspring 12 is provided with a front portion of the storage unit 8 (shelf 2) and an urging force transmitting member (case 13) for transmitting the urging force to the article S located at the rearmost end of the row. It becomes the structure spanned over between (it shall be included in the said structure, even when the thread-shaped member 15 is interposing as mentioned above). As a result, when a large number of articles S are stored, the case 13 is located behind the shelf 2, so that the filamentous member 15 is pulled out for a long time, that is, the mainspring 12 of the mainspring 12 via the reel 15a. The amount of winding is large, and the urging force on the article S is large. Every time the article S is taken out from the loading / unloading port 6, the case 13 itself moves forward by the biasing force of the mainspring 12 and presses the entire row of articles S forward, and each time the case 13 moves forward. The mainspring 12 is loosened, and the urging force on the article S is gradually reduced. Therefore, when the number of stored items decreases, the load on the article S can be reduced,
When the frontmost article S is taken out, the sudden sliding movement of the remaining stored articles S is prevented.

Depending on the setting of the amount of movement of pulling out the shelves 2 and the shape of the biasing force transmitting member (case 13), the mainspring 12 (thread member 15) may be moved toward the front portion of the housing 3 and the biasing force. It is also possible to span the transmission member.

Next, the urging force stopping means 16 (see FIG. 2) for stopping the urging force of the urging means 11 with respect to the article S when the shelf 2 is pulled out to a predetermined position will be described.
The urging force stopping means 16 is an effective means when, for example, the article S is replenished in the shelf 2.

Here, the storage rack device 1 according to the present embodiment.
Has a restricting means (not shown) for restricting the withdrawal movement of the shelf 2, and a releasing means (not shown) for canceling the restriction of this restricting means. In FIG. 2, the state in which the shelf 2 of the fourth step from the top is pulled out to form the loading / unloading opening 6 for the article S indicates a state in which the loading means 6 is not further pulled out by the restricting means, and the loading / unloading article 6 can be taken out. Only a predetermined number of S at the front end of the row can be taken out, such as one S. Usually, the article S is taken out in this state.

When the number of stored articles S has decreased, the regulating means is released, so that the shelf portion 2 is brought closer to the front like the shelf portion 5 on the fifth stage from the top in FIG. The article S can be pulled out to the side so that the articles S can be easily replenished. That is, the withdrawal process of each shelf 2 is regulated by the regulation means and the withdrawal / removal opening 6
The first withdrawal stroke up to the formation of the first withdrawal stroke and the second withdrawal stroke with which the regulation means is released and can be further withdrawn toward the front side. The restricting means and the releasing means are
For example, a known structure used for drawer of a desk or the like can be applied, and in the present embodiment, the regulated shelf portion 2 is slightly lifted and pulled up to be further pulled out to the front side.

Therefore, if the urging force by the urging means 11 is stopped in the second withdrawal stroke mainly for the purpose of replenishing the article S, an unreasonable force is exerted on the new article S to be replenished. Without this, the worker can smoothly replenish the article S to the shelf 2.

In the present embodiment, the urging force stopping means 16
Has a structure in which the locking portion 17 provided so as to move integrally with the case 13 is locked to the locked portion 18 provided on the housing 3 side. Specifically, FIG.
As shown in (a), a hook-shaped hook portion 14b forming a locking portion 17 is formed on the lower portion of the bracket 14. As described above, the bottom plate 10 of the shelf 2 is formed with the slot 10a along the front-rear direction corresponding to each storage passage for articles, and the hook 14b is provided with the slot 1a.
It projects to the lower side of the shelf 2 through 0a. on the other hand,
As shown in FIG. 2, a horizontal beam-shaped hook locking member 19 that constitutes the locked portion 18 is attached to the front portion of the housing 3.

With the above structure, when the shelf 2 is pulled out like the shelf 2 in the fifth stage from the top shown in FIG. 2, the hook 14b is locked to the hook locking member 19 during the pulling out. In this case, the forward movement of the case 13, which is the urging force transmitting member, is prevented. Therefore, when the shelf 2 is fully pulled out, the case 13 does not have an urging force on the article S, and thus the shelf 13 has no urging force. It will be in the state of waiting behind 2 and the shelf 2
Therefore, a wide replenishment space for the article S can be secured.

At this time, when the article S is still stored in the storage passage, the rearmost article S does not come into contact with the case 13 side, so that it is slender and has an unstable standing state such as an ampoule container. In the case of a shape, it tends to fall to the rear side. Especially when pulling out the shelf 2 for supplementation,
Alternatively, when the shelf 2 is returned after the replenishment is completed, the inertia force acting on the article S causes the article S to fall easily. Further, even if the article S is completely empty when the shelf 2 is pulled out, when replenishing a new article S, the article S on the rearmost end side is replenished while being careful not to fall down. I need to
In the case of a small ampoule container or the like, since the width of the storage passage is formed to be narrow, it is difficult to insert a finger, and there is a problem in refill workability.

To solve this problem, in the storage passage, that is, between the article S located at the rearmost end of the row and the urging means 11 (in this embodiment, the case 13 which is the urging force transmitting member), the front and rear sides are independently operated. If the article support member 20 that is movably provided and that can support the article S located at the rearmost end of the row in an upright state is provided, it is possible to effectively prevent the article S from collapsing at the time of replenishment, and it is smooth. Replenishment work can be performed.

As shown in FIGS. 4 to 6, the article support member 20 is formed with protrusions 20a on both side surfaces thereof, which engage with the guide grooves 9a (FIG. 5A) of the partition plate 9 described above. ing. Further, the article support member 20 is provided with an operating portion 20b that is formed upright so as to protrude above the upper end of the partition plate 9, and one side surface of the upper portion of the operating portion 20b is provided with an upper edge of the partition plate 9 on one side. The protrusion 20c is formed in this manner. As described above, the article support member 20 can be smoothly moved along the storage passage by being guided by the partition plates 9 located on both sides via the protrusions 20a and 20c, and the operator can operate the operation unit. It is used as a mode in which a finger is applied to 20b to slide it back and forth.

With the interposition of the article support member 20, the shelf 2 is pulled out while the article S is still stored in the storage passage, and the urging force for the article S is lost by the urging force stopping means 16. However, the article S at the rearmost end is supported by the article support member 20 in the upright state, and the fall is prevented.

Further, as an example of using the article support member 20 when replenishing a new article S with the storage passage emptied, the article support member 20 is preliminarily set at an arbitrary position (for example, in the middle) of the storage passage. Then, the article S is replenished to the front portion of the vehicle. The article at the rearmost end of the row is in a state of being supported by the article support member 20, and smooth replenishment work can be performed. As another usage example, first, the article support member 2
0 is located on the front side, and the first one is replenished between the front end of the shelf 2 and this article support member 20. Next, the second piece is replenished by inserting it between the front end of the shelf 2 and the first article S. When inserted, the second article S pushes the first article S and the article support member 20 rearward, but the first article S slides backward together. Since it is supported by, the fall is prevented. In this way, new articles S are sequentially replenished, and the first article S (which is the last article in the row) is always supported by the article support member 20.
As a result, the worker can perform a smooth replenishment work without worrying about the falling of the article S.

Here, as described above, the article support member 2
When 0 is preliminarily positioned at an arbitrary position in the storage passage to replenish the article S, the rearmost article S may fall depending on the replenishment position. When an ampoule container or the like falls, the width of the storage passage is narrow, so it is difficult for the fingers to enter, and the standing work is troublesome. Therefore, in the article support member 20, when the article S located at the rearmost end is tilted backward, the top portion or the side portion thereof is pressed so as to be able to stand up, as shown in FIG. Article raising means 2 including an inclined surface portion
With the configuration including 1, the fallen article S can be easily raised.

In this embodiment, the curved surface portion 2 has a concave shape so as to face the front side from the vicinity of the bottom of the article supporting member 20.
Forming 2. As a result, as shown in FIG. 7A, even when the article S falls down, the article support member 20
Applying a finger to the operation portion 20b of the above and sliding it to the front side, the curved surface portion 22 presses the top of the article S so as to lift it (state of FIG. 7 (b)), as shown in FIG. 7 (c). The article S is supported in an upright state. With respect to the article erection means 21, the article S can be smoothly erected by a configuration having an inclined surface portion, although it depends on the shape of the article S.

As shown in FIG. 6A, on the side surface of the article support member 20, the protrusions 20a and 20c are formed.
If the fitting holes 20d and 20e are formed so as to correspond to
These protrusions 20a, protrusions 20c, fitting holes 20d, 2
6e, it becomes possible to integrally connect a plurality of article support members 20 in the lateral direction, as shown in FIG. 6B, and it is possible to easily accommodate various storage passage widths of the articles S. As a result, the parts relating to the article supporting member 20 can be shared, and the economical storage rack device 1 can be obtained.

Next, the storage rack device 1 of the present embodiment is in a normal use state, that is, in the state of the above-described first pulling stroke (the shelf S 2 at the fourth stage from the top in FIG. In the state where the inlet / outlet opening 6 of the
A detection means 23 for detecting the article S taken out from the shelf 2 is provided. The detection means 23, as shown in FIG.
A plurality of articles are provided inside the front part of the frame 7 so as to correspond to the storage passages for the articles S.

The detecting means 23 is not particularly limited, but in the present embodiment, it comprises a limit switch 24 as shown in FIG. In this figure, a switch cover 26 is attached to the inside of the front part of the frame 7 so as to be rotatable around an axis 25 whose axial direction is the width direction of the storage passage. In the state of FIG. 8A, the entire article S is urged forward by the urging means 11, and in this state, the foremost article S presses the switch cover 26 to cause the limit switch 24 to move. Electrical signal from ON
Is in the state of.

When the frontmost article S is taken out from this state, as shown in FIG. 8B, the pressing state from the frontmost article S is momentarily released, so that the limit switch 24 is turned off. Become. Then, when the article S at the foremost end is completely taken out, the article S located at the second position is urged by the urging means 11 to press the switch cover 26, so that the limit switch 24 is turned on again. (State of FIG. 8C). Of course, the ON-OFF mode of the electric signal from the limit switch 24 is reversed,
That is, when the switch cover 26 is pressed,
The configuration may be such that an OFF signal is obtained.

As described above, the number of the articles S taken out can be known by counting the ON signal and the OFF signal. For example, the number of the articles S taken out can be subtracted from the preset number of articles to be stored in the shelf 2. The number of stored items can be counted. As shown in FIG. 2, in the lower part of the housing 3, a control device 27 for processing the signal from the limit switch 24.
Is mounted, and the top plate of the housing 3 displays the number of articles stored,
A touch panel type display device 28 is provided for performing initial setting of the number of stored articles when the articles S are replenished.

Although the preferred embodiment of the present invention has been described above, the layout, shape, number and the like of each constituent element are not limited to those shown in the drawings, and the present invention is appropriate without departing from the spirit of the present invention. Design change is possible.
