In this embodiment, the storage area 3 has a three-stage structure as shown in FIG. Each stage has a structure in which three rows of conveyor devices (conveying devices) are arranged in parallel, as shown in FIG.
Out of the three rows of conveyor devices, the outer two rows constitute storage areas. The central conveyor system also constitutes the delivery path.
Hereinafter, the conveyor device forming the storage area will be referred to as a storage region conveyor (storage region) 10 , and the conveyor device forming the delivery path region will be referred to as a delivery route conveyor (delivery route) 11 .

Storage area conveyor 10 is divided into a plurality of zones. That is, the storage area conveyor 10 is formed by linearly connecting short conveyor devices called zone conveyors 16 .
The zone conveyors 16 of each zone are all short roller conveyors (also called roller conveyors), and a plurality of conveying rollers (biasing means) 15 are arranged at regular intervals.

That is, the zone conveyor 16 is a short roller conveyor as shown in FIG. It is supported by
The conveying roller 15 is composed of a freely rotating driven roller and a motor-incorporated roller. In this embodiment, there is only one motor-incorporating roller, and all others are driven rollers. A drive motor (not shown) is built in the motor-incorporating roller as a driving device.

A transmission belt (not shown) is wound between the conveying rollers 15 adjacent to each other in the zone conveyor 16 . Therefore, the rotational driving force of the motor-incorporating roller can be transmitted to all the driven rollers.
A plurality of transport rollers 15 constitute a storage area side transport surface 23 . The transport surface 23 is horizontal.

The side frames 20 and 21 employed in this embodiment have different heights of the highest portions (hereinafter simply referred to as heights) on the left and right sides as shown in FIG. 1(b). Of the pair of side frames 20 and 21, the side frame 20 (hereinafter referred to as the outer frame 20) arranged outside the storage area 3 is tall and has a side on the delivery route conveyor (delivery route) 11 side. The frame 21 (hereinafter referred to as inner frame 21) has a low height.

In relation to the conveying surface 23 formed by the conveying rollers 15 , the outer frame 20 is higher than the conveying surface 23 at its highest portion.
On the other hand, the inner frame 21 has a height lower than the conveying surface 23 at the highest portion. That is, the height of the inner frame 21 on the delivery path side is equal to or lower than the transport surface 23 of the transport roller 15 .
The conveying rollers 15 are installed in a horizontal posture, and the upper surface of each conveying roller 15 is the highest portion of the conveying roller 15 where the height is the highest. In this embodiment. The height of the highest portion of the conveying roller 15 is equal to or higher than the height of the inner frame 21 .

In this embodiment, as shown in FIGS. 1A and 2, each conveying roller 15 is installed in an inclined posture when viewed from above. That is, the angle formed by the outer frame 20 and the conveying roller 15, which is on the traveling direction side of the storage area conveyor 10, is an acute angle.
Although all the transport rollers 15 are attached obliquely in this embodiment, only some of the transport rollers 15 may be attached obliquely.
The storage area conveyor 10 conveys articles linearly from the base end side to the front end side as indicated by the arrow in FIG. Therefore, the articles M are urged away from the delivery route conveyor 11 during transportation.

Also, as shown in FIG. 2, each zone conveyor 16 is provided with a load sensor 25 . The inventory sensor 25 is a sensor that detects the presence or absence of articles.
The presence sensor 25 is formed by arranging a plurality of reflective photoelectric sensors 26 in a straight line.

Next, the delivery route conveyor 11 will be explained. The delivery route conveyor 11 is also formed by connecting a plurality of zone conveyors 30 in a straight line.
The zone conveyor 30 also has a plurality of transport rollers 35 arranged at regular intervals.
The transport rollers 35 of the zone conveyor 30 also include driven rollers and motor-incorporating rollers, and adjacent transport rollers 35 in the zone conveyor 30 are wound with a transmission belt (not shown). Therefore, the rotational driving force of the motor-incorporating roller can be transmitted to all the driven rollers.
A plurality of transport rollers 35 constitute a delivery route side transport surface 33 . The delivery route side conveying surface 33 is horizontal.

As shown in FIG. 1(b), the side frames 31 and 32 of the zone conveyor 30 have the same height, and both of them are equivalent to the delivery road side conveying surface 33 of the zone conveyor 30. As shown in FIG. The side frames 31 , 32 are lower in height than the inner frame 21 of the storage area conveyor 10 .
As shown in FIGS. 1A and 2, in the delivery route conveyor 11, each transport roller 35 is installed straight. That is, the angle formed by the side frames 31 and 32 and the conveying roller 35 is vertical.
Each zone conveyor 30 of the delivery route conveyor 11 is also provided with a load sensor 38 . The structure of the presence sensor 38 is the same as that provided in the storage area conveyor 10. FIG.
The load sensor 38 is also provided in a gap between the conveying rollers 35 and below the conveying surface 33 .

In the article storage apparatus 1 of this embodiment, storage area conveyors 10 are arranged on both sides of a delivery path conveyor 11 .
Power lines for supplying power to the storage area conveyor 10 and the delivery route conveyor 11, signal lines including the

load sensors

25 and 38, and control devices are is also below.

In this embodiment, as shown in FIGS. 1(b) and 3, the installation height of the central delivery path conveyor 11 is lower than the storage area conveyors 10 on both sides.
Therefore, the delivery path side transport surface 33 of the delivery path conveyor 11 is lower than the storage area side transport surface 23 of the storage area conveyor 10 .
Focusing on the boundary portion between the storage area side transport surface 23 and the delivery route side transport surface 33, the height from the storage area side transport surface 23 to the delivery route side transport surface 33 decreases in order.
That is, the inner frame 21 of the storage area conveyor 10 and the side frames 31 and 32 of the delivery path conveyor 11 are located between the storage area side conveying surface 23 and the delivery route side conveying surface 33 .

The inner frame 21 of the storage area conveyor 10 has a highest height lower than the storage area side conveying surface 23 . The side frames 31 , 32 of the delivery channel conveyor 11 are lower than the inner frame 21 of the storage area conveyor 10 . Further, the delivery route side conveying surface 33 of the delivery route conveyor 11 is equivalent to the height of the highest portions of the side frames 31 and 32 of the delivery route conveyor 11 .
Further, the inner frame 21 of the storage area conveyor 10 and the side frames 31, 32 of the delivery path conveyor 11 do not have protrusions such as sensors.
Therefore, the height decreases in order from the storage area side conveying surface 23 to the delivery route side conveying surface 33 .
In the article storage apparatus 1 of this embodiment, articles can be transferred to the delivery route conveyor 11 from the entire length of the storage area conveyor 10 . That is, in this embodiment, the entire area of the delivery route conveyor 11 is a transferable area where articles can be transferred. In addition, there is no obstacle between the storage area of the transferable area and the delivery route to prevent the movement of the article toward the delivery route.

In the article storage apparatus 1 of this embodiment, a transfer device 17 is attached to a storage area conveyor 10 that constitutes a storage area.
The transfer device 17 is a device that transfers articles on the storage area conveyor 10 to the delivery route conveyor 11 .
The transfer device 17 is composed of a payout means 18 and a moving device 28 . The transfer device 17 moves along the storage area conveyor 10 by the moving device 28 , extends the dispensing means 18 , and pushes the article Ma on the storage area conveyor 10 to the delivery route conveyor 11 .

The end of the storage area 3 is connected to the transport path 12 of the loading/unloading area 2, as shown in FIG.
The transport path 12 is also connected to a conveyor device called a zone conveyor.

Direction changers

13 a , 13 b , 13 c are arranged in zones of the transport path 12 connected to the storage area 3 .
The

direction changing devices

13a, 13b, and 13c can arbitrarily change the conveying direction of the article.
That is, the

direction changing devices

13a, 13b, and 13c can move the articles straight, and can also change the traveling direction of the articles vertically to either the left or right direction.

Hereinafter, the operation for carrying an article M into the storage area 3 will be described with reference to FIG. A series of operations for carrying in the articles M are automatically executed by a command from a control device (not shown).
When the article M is carried into the storage area 3, the article M is carried in using the transport path 12 as shown in FIG. 4(a). Then, the conveying direction is changed to the side of the storage area conveyor 10a by the direction changing device 13a connected to the storage area conveyor 10a, and the article M is sent to the storage area conveyor 10a. Articles M are advanced to the back by the storage area conveyor 10a.
1 and 2, the storage area conveyor 10a employed in the present embodiment is installed in such a manner that each conveying roller 15 is inclined when viewed from above.
Therefore, when the conveying roller 15 rotates, the article M is given a vector directed toward the outer frame 20 with respect to the longitudinal direction of the storage area conveyor 10a, and advances obliquely as shown in FIG. 4(a).
That is, the article M does not advance straight, but rather in a direction toward the outer frame 20 .
As a result, the article M contacts the outer frame 20 and is guided by the outer frame 20 to advance. Therefore, the articles M move forward while being separated from the delivery route conveyor 11 .

Here, in the storage area 3 of this embodiment, since there is no obstacle between the storage area conveyor 10a and the delivery route conveyor 11, if an article meanders and moves to the delivery route conveyor 11 side, the delivery route conveyor 11 side fall into.
On the other hand, in the present embodiment, since the articles M move away from the delivery route conveyor 11, the articles M are prevented from falling toward the delivery route conveyor 11 side.

By repeating this operation, one article M is placed on each zone conveyor 16 of the tube area conveyor 10a as shown in FIG. 4(b).

When storing an article on the storage area conveyor 10b, as shown in FIG. 4(c), the article M goes straight through the direction changing device 13a and reaches the direction changing device 13c connected to the storage area conveyor 10b. Then, the conveying direction is changed to the storage area conveyor 10b by the direction changing device 13c, and the article M is sent to the storage area conveyor 10b. Articles M are advanced to the back by the storage area conveyor 10b. By repeating this operation, the articles M are placed in each zone of the storage area conveyor 10b.

Next, referring to FIG. 5, the operation of unloading the article M from the storage area 3 will be described. A series of operations for unloading the article M are automatically executed by a command from a control device (not shown).
In the article storage apparatus 1 of this embodiment, articles M can be carried out from any zone of the

storage area conveyors

10a and 10b.
For example, as shown in FIG. 5A, an article M is placed on each zone conveyor 16, and an article Ma stored in the intermediate portion of the storage area conveyor 10b is carried out.
In FIG. 5(a), the transfer device 17 is on standby at the leading ends of the

storage area conveyors

10a and 10b. When carrying out the article Ma, the moving device 28 of the transfer device 17 is driven to move the transfer device 17 to the side of the article Ma. That is, as shown in FIG. 5B, the transfer device 17 is moved to the zone where the article Ma is placed. Then, the transfer device 17 is driven in the zone where the article Ma is placed, and the article Ma is transferred from the storage area conveyor 10b to the delivery route conveyor 11 as shown in FIG. 5(b).
That is, the transfer device 17 is moved along the storage area conveyor 10 to the rear surface of the desired article Ma. Then, the dispensing means 18 is extended to push Ma on the article on the storage area conveyor 10 to the delivery route conveyor 11.例文帳に追加

Here, in the present embodiment, the height from the storage area side conveying surface 23 to the delivery route side conveying surface 33 decreases in order, and there are no obstacles.
Therefore, when pushed by the dispensing means 18 , the article Ma moves laterally and moves to the delivery route conveyor 11 .

Then, the article Ma drives the delivery route conveyor 11 and advances toward the direction changing device 13b as shown in FIG. 5(c).
Here, since the delivery route conveyor 11 is equal to the height of the highest portion of the side frames 31 and 32, the side frames 31 and 32 cannot correct the route when the article Ma meanders. However, in the article storage apparatus 1 of this embodiment, the installation height of the central delivery path conveyor 11 is lower than the storage area conveyors 10 on both sides.
When an article meanders while it is being moved on the delivery path conveyor 11, the article touches the outer surface of the inner frame 21 of the storage area conveyor 10 and is guided by the outer surface of the inner frame 21 to advance linearly.
Therefore, the article does not climb onto the storage area side.

The direction of the article Ma is changed by the direction changing device 13b and carried out to the left side of the drawing.
In the meantime, as shown in FIG. 5(d), the storage area conveyor 10b is driven to drive the zone on the upstream side of the vacant zone, and the wafers are placed in the zone on the upstream side of the vacant zone. Advance item M.

The storage area conveyor 10 of the storage area 3 conveys articles in a one-way direction from the side of the

direction changing devices

13a and 13c toward the back side. On the other hand, the delivery route conveyor 11 in the storage area 3 conveys the articles in one way from the back side to the direction changing device 13b.
In the article storage apparatus 1 of the present embodiment, since the article transport paths of the loading/unloading area 2 and the storage area 3 are both one-way, articles can be continuously loaded and unloaded.

In the embodiment described above, the installation height of the central delivery route conveyor 11 is set lower than that of the storage area conveyors 10 on both sides, thereby smoothing the movement of the articles M from the storage region conveyors 10 and increasing the height of the delivery route conveyor. Meandering of the article M when moving the article 11 can be prevented. That is, the storage area conveyors 10 on both sides and the delivery route conveyor 11 in the center are arranged in a concave shape to facilitate the movement of the articles M from the storage region conveyors 10, and to prevent the movement of the articles M when the delivery route conveyor 11 is moved. Meandering can be prevented.
Also, by arranging the conveying rollers of the storage area conveyor 10 obliquely, the article M is brought to the outside and prevented from going to the delivery route conveyor 11 side during movement.

Although the embodiment described above is recommended, the present invention is not limited to this configuration.
For example, like the storage area 40 shown in FIG. Measures to prevent meandering of the article M are also recommended.
In the storage area 40 shown in FIG. 6, the storage area conveyors 41 on both sides are inclined in the horizontal direction.
That is, the storage area conveyor 41 has an inclined conveying surface 23, and the delivery route conveyor 11 side faces upward.

As for the storage area conveyor 41, the outer frame 20 also has a higher height and the inner frame 21 has a lower height.
In the storage area conveyor 41 , the transport rollers 15 are in an inclined posture, and the upper surfaces of the corner portions of the transport rollers 15 are the highest parts H of the transport rollers 15 . In this embodiment, as shown in FIG. 6, the height of the highest portion of the conveying roller 15 is equal to or higher than the height h of the inner frame 21 .
In this embodiment as well, the delivery path side of the frame portion of the storage area conveyor 41 has a height equal to or lower than the maximum height of the transport surface of the transport roller 15 as the biasing means, and the height of the delivery path side of the storage area conveyor 41 is It is higher than the delivery surface 33 of the delivery channel.
Each transport roller 15 is arranged straight. That is, the angle formed by the outer frame 20 and the conveying roller 15 is vertical.
The structure of the delivery route conveyor 11 is the same as the previous embodiment.

In the storage area 40 , the delivery route conveyor 11 side of the storage region conveyor 41 is inclined upward, and the delivery route conveyor 11 side of the storage region conveyor 41 is positioned higher than the delivery route conveyor 11 .
Conversely, the delivery path side transport surface 33 of the delivery path conveyor 11 is lower than the storage area side transport surface 23 of the storage area conveyor 41 . Therefore, it is possible to prevent meandering of the articles M when moving on the delivery route conveyor 11 .
In the present embodiment, focusing on the boundary portion between the storage area side conveying surface 23 and the delivery route side conveying surface 33, the height from the edge of the storage area side conveying surface 23 to the delivery route side conveying surface 33 decreases in order. It's becoming
Therefore, when pushed by the dispensing means 18 , the article Ma moves laterally and smoothly moves to the delivery route conveyor 11 .
In addition, since the conveying surface 23 of the storage area conveyor 41 is laterally inclined, the article M is given a vector directed toward the outer frame 20 by gravity, and advances in an oblique direction. As a result, the article M contacts the outer frame 20 and is guided by the outer frame 20 to advance. Therefore, the articles M move forward while being separated from the delivery route conveyor 11 .

As in the present embodiment, the framework for supporting the storage area conveyor 10 and the delivery route conveyor 11 is generally made of a steel frame on which the storage area conveyor 10 and the like are placed. A suspension structure such as 7 may be used.

65,66.

An intermediate installation member 77 (support member) is fixed to the hanging

members

75 and 76 .
The storage area conveyor 10 and the delivery route conveyor 11 are supported by the post-side installation member 68 and the intermediate installation member 77 and suspended from the beam member 67 .

Most of the conveying rollers employed in the embodiments described above have a constant outer diameter, but may have a large diameter portion and a small diameter portion. That is, roller-shaped members may be linearly arranged on one axis.

In the embodiment described above, the delivery path conveyor 11 is installed between the two rows of storage area conveyors 10, and the central delivery path conveyor 11 carries out the articles M discharged from the two rows of storage area conveyors 10. The number of storage area conveyors 10 and the number of delivery route conveyors 11 may be the same.
The delivery route conveyor 11 is mainly used for carrying out the articles M, but it is also possible to keep the articles M temporarily.
