Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an article storage device that prevents deflection of the bottom plate of a wide carrier housed in a housing.

[Technical background of the invention and its problems] For example, in an article storage device for storing one quantity of articles in a relatively small space, a large number of carriers for storing each article are housed in a housing, and each There is one in which a desired carrier is selectively moved to an article insertion/ejection opening provided on the front surface of the housing by driving the carrier in a circular manner in the vertical direction.

Such an article storage device is constructed as shown in the sectional view of FIG. 7, for example. That is, numeral 1 in the figure is a box-shaped housing, and a pair of sprockets 2a and 2b, which are rotationally driven by a motor (not shown), are arranged in parallel at the upper and lower parts of the housing 1. Chain belt 3 between these sprockets 2a and 2b
is suspended, and a pair of support arms 4a, 4b are attached to this chain belt 3 at regular intervals. The support shaft 5 of this support arm 4a, 4b
A side plate of a carrier 6 for storing various articles is rotatably supported. Further, one position holding arm 7 is fixed to each support shaft 5 in a non-rotatable manner, and a guide roller 8 is rotatably supported at the other end of this position holding arm 7.

Oval annular tracks 9 having circular arc portions at the top and bottom are formed on the left and right inner surfaces of the housing 1, respectively. This annular track 9 has a concave groove shape, and has the function of keeping each carrier 6 in a horizontal state at all times by fitting the guide roller 8 therein. Further, a table 10 is provided projecting approximately horizontally from the front surface of the casing 1, and an article insertion/ejection opening 11 is provided above the table 10.

Therefore, one of the sprockets 2a, 2
When b is rotated by a motor, sprocket 2
A chain belt 3 suspended between a and 2b is driven to circulate, and each carrier 6 circulates while maintaining a horizontal state. Therefore, by rotating the sprockets 2a and 2b by a preset angle, the desired carrier 6 can be moved to the position of the article insertion/ejection opening 11, and the carrier 6 can be moved through the article insertion/ejection opening 11. Items can be taken in and taken out of 6.

Each carrier 6 used in such an article storage device generally has a long dimension in the width direction, so depending on the weight of the stored articles, the front edge (stile) of the bottom plate constituting each carrier 6 may move downward. There is a concern that it may sag. In order to solve this problem, in the conventional device, as shown in FIG. By attaching a reinforcing material 14 of an appropriate thickness throughout, the amount of deflection of the stile 15 of the bottom plate 13 is suppressed.

However, a reinforcing material 14 having a certain thickness as shown on the lower surface of the bottom plate 13 of each carrier 6
When the carriers 6 are attached, the article storage space distance between the carriers 6 is reduced, resulting in a problem that the article storage capacity of the entire apparatus is reduced.

In order to avoid this decrease in goods storage capacity,
As shown in the figure, instead of the reinforcing material 14, a top plate 16 is attached to each carrier 6 across the two side plates 12a and 12b, and a partition plate 17 connects the top plate 16 and the bottom plate 13. something is proposed. With such a carrier 6, the stress that causes the stile 15 to bend downward when an article is placed on the bottom plate 13 is converted into a shearing force that tends to deform the partition plate 17 into a diamond shape. This partition plate 17
Since the shearing strain caused by the shearing force is very small, the stile 15 hardly bends.

However, as mentioned above, the bottom plate 13 and the top plate 1
Even in an article storage apparatus employing a carrier 6 provided with a partition plate 17 for absorbing stress between the carrier 6 and the carrier 6, the following problems still occur. That is,
The partition plate 17 is generally fixed to the bottom plate 13 and the top plate 16 by welding or screwing in order to obtain a certain connection strength. However, in the case of the welding method, once the carrier 6 is assembled and manufactured, it is almost impossible to disassemble it, so when transporting this article storage device, a huge amount of space is required, resulting in an increase in packing and transport costs. There is. Furthermore, when transporting the carrier 6, it is common to carry it by hand from getting off the vehicle to the installation site, but in this case there is a drawback that the number of personnel required to transport the carrier 6 increases. Furthermore, if the carrier 6 is disassembled and transported to the installation location specified by the customer without attaching the partition plate 17 at the time of shipment from the factory, and the partition plate 17 is welded, the welding equipment and the worker performing the welding It is necessary to dispatch a person to the installation site. There was also a risk that the amount of work at the installation site would increase.

On the other hand, the bottom plate 13 is fixed by screwing the partition plate 17.
When fixing it to the top plate 16, it is possible to disassemble and transport it, but since the screw portion protrudes from the top surface of the bottom plate 13 and the bottom surface of the top plate 16, the partition plate 1
Items cannot be stored in the carrier 6 because they are in close contact with the carrier 7.
As a result, the capacity for storing articles in each carrier 6 is reduced, and there is a risk that the article storing capacity of the entire apparatus will be reduced. Furthermore, if the threaded portion protrudes into the interior, there is a possibility that the stored articles may be damaged.

[Purpose of the invention] The invention was made based on the above circumstances, and its purpose is to form long holes in the bottom plate and top plate of the carrier, and to form long holes in the partition plate. By penetrating and locking the protrusion, welding can be performed. To provide an article storage device that can fix partition plates without using screws, can be disassembled and transported, and can streamline and simplify assembly work at an installation site.

[Summary of the invention] In each carrier of the article storage device of the invention, as a means for fixing the partition plate to the bottom plate and the top plate that connect a pair of opposing side plates, the position where the partition plate of the bottom plate and the top plate are connected is determined. A long hole is formed in each of the partition plate, and a first protrusion that passes through the long hole in the bottom plate and is bent perpendicularly to the partition plate, and a long hole in the top plate that passes through the long hole in the partition plate. A second protrusion is formed perpendicular to the partition plate and bent in a direction opposite to the first protrusion.

[Embodiment of the invention] An embodiment of the invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing each carrier of the article storage device of the embodiment. Note that the general configuration of the entire article storage device is the same as the configuration shown in FIG. 7, so a description thereof will be omitted. In each carrier 21 of this embodiment, a pair of side plates 22a and 22b are arranged on both sides.
The space between them is connected by a bottom plate 23 and a top plate 24.
This connection is made by screwing, for example. Three partition plates 25a, 25b, and 25c are fixed to the bottom plate 23 and the top plate 24 at equal intervals between the side plates 22a and 22b.

That is, as shown in FIGS. 2a and 2b, each partition plate 25a of the bottom plate 23 and the top plate 24,
Two elongated holes 26a and 26b are formed at positions where 25b and 25c abut, respectively. Each of these long holes 26a, 26b has a rectangular shape, and the short side of the rectangle is set to a value slightly larger than the thickness of each partition plate 25a, 25b, 25c. In addition, as shown in the figure, the width of the elongated hole 26a, 26b is at each position that abuts the elongated hole 26a, 26b on the side of each partition plate 25a, 25b, 25c that abuts the bottom plate 23.
It is slightly shorter than the long side of the partition plates 25a, 2.
2 bent in the direction perpendicular to 5b and 25c
First protrusions 27a and 27b are formed. On the other hand, each elongated hole 26a, 26 on the side of each partition plate 25a, 25b, 25c that comes into contact with the top plate 24
As shown in the figure, there are two second protrusions bent in the direction perpendicular to the partition plates 25a, 25b, 25c and in the opposite direction to the first protrusions 27a, 27b. Projections 28a and 28b are formed.

FIG. 3 is a sectional view when the partition plates 25a to 25c are assembled and fixed to the bottom plate 23 and the top plate 24.
As shown in the figure, the first
The second protrusions 27a, 27b pass through the elongated holes 26a, 26b and are locked on the lower surface of the bottom plate 23, and the second protrusions 28a, 28b pass through the elongated holes 26a, 26b and are locked on the upper surface of the top plate 24. It is locked.

If the article storage device is configured in this way,
When articles are stored in each carrier 21, the downward stress applied to the stile 29 of the bottom plate 23 due to the weight of each article is transferred to each partition via the first protrusions 27a and 27b locked to the lower surface of the bottom plate 23. Plate 25a, 2
It is transmitted to 5b and 25c. Furthermore, each partition plate 25a,
The second protrusion 28a, via 25b, 25c.
28b passes through the elongated holes 26a and 26b and is transmitted to the locked top plate 24. Therefore, as shown in FIG. 4, the downward stress of the stile 29 is converted into a shearing force of each partition plate 25a, 25b, 25c and a bending stress of the top plate 24. As a result, as shown by the dotted lines in the figure, each partition plate 25a, 25b, 25
c tends to curve downward into a diamond shape, and the top plate 24 and bottom plate 23 curve downward. However, since the bending strain caused by the shear strain and the shared bending stress is minute, the stile 29 hardly bends.
Note that since the amount of deflection of the stile 29 is generally maximum at the center, it is desirable to provide at least one partition plate at the center.

Furthermore, since a screw fastening method is not adopted as a means for fixing each partition plate 25a, 25b, 25c to the bottom plate 23 and top plate 24, the screw portion does not protrude into the part of each carrier 21 where articles are stored. do not have. Therefore, there is no fear of damaging the stored articles, and the article storage volume of each carrier 21 can be utilized to the maximum.

Furthermore, since welding is not used as the fixing means, the device can be disassembled and transported, and the efficiency of assembly work at the installation site can be improved and the work can be simplified.

In other words, when assembling the carrier 21,
As shown in FIG. 5a, first, place the bottom plate 23,
Next, the bent first projections 27a, 27b of the partition plates 25a, 25b, 25c are inserted into the elongated holes 26a, 26b. In addition, each long hole 26
a, 26b into the respective first projections 27a, 27b.
Only the . Each protrusion 27a, 27
When b is inserted, each partition plate 25a, 25b, 2
A first protrusion 27a, 2 is provided at the opposite end (upper end) of 5c.
Each second protrusion 28a, 28b formed by bending in the opposite direction to 7b necessarily faces upward.

In this normal state, as shown in FIG. 5b, the top plate 24
is placed so that its respective elongated holes 26a, 26b are inserted into the respective second protrusions 28a, 28b.

Thus, as shown in FIG.
28b, the top plate 24 and each partition plate 25a, 25b, 25c are rotated in the direction of arrow C in the figure.

Then, the bottom plate 23 and the top plate 24 are properly opposed to each other and fixed to both side plates 22a and 22b with screws, for example.

In this way, each partition plate 25a, 25b, 25c
first and second protrusions 27a formed at both ends of the
By bending 27b, 28a, and 28b in opposite directions, the bottom plate 2 is formed as described above.
3. Top plate 24 and each partition plate 25a, 25b, 2
It becomes possible to assemble the carrier 21 without applying any external force to 5c. Further, even when disassembling the once assembled carrier 21 for transportation, it can be easily disassembled without damaging each component by performing the above-described procedure in reverse.

Incidentally, the first and second projections 27a, 28a
If they are bent in the same direction, once assembled, as shown in Figure 6a,
Original bottom plate 23, top plate 24, and each partition plate 25
It becomes very difficult to decompose into a and 25b.
That is, since each protrusion faces the same direction, for example, the first protrusion 27 of each partition plate 25a, 25b
If an attempt is made to rotate it in the direction of arrow A around a position near a, the inner surface of the first protrusion 27a will come into contact with the lower surface of the bottom plate 23. Conversely, if it is attempted to rotate in the direction of arrow B, the inner surface of the second protrusion 28a will come into contact with the upper surface of the top plate 24.

Note that even if there is only one partition plate 25a,
As shown in FIG. 6b, it is necessary to rotate the top plate 24 itself significantly, and one end of the top plate 24 is attached to the bottom plate 24.
It comes into contact with.

It is also possible to reduce the number of component parts compared to the screw fastening method.

In addition, here, the side plates 22a, 22b and the top plate 24
Fixing to the base plate 23 is not particularly limited as long as it is a strong fixing method. For example, even if it is fixed with screws, there are few fixing points, so it does not affect the overall work efficiency much. Further, in the embodiment, three partition plates were provided, but the number of partition plates is not particularly limited and can be set arbitrarily as necessary. Further, the number of first and second protrusions provided is not particularly limited either.

[Effect of the invention] As explained above, according to the invention, long holes are formed in the bottom plate and the top plate of the carrier as a means for fixing the partition plate to the bottom plate and the top plate, and the partition plate is inserted into the long holes. The formed protrusion is penetrated and locked. Therefore, welding. The partition plate can be fixed without using screws, it can be disassembled and transported, and it is possible to streamline and simplify the assembly work at the installation site.
