Length L-1 An embodiment of the present invention illustrated in FIGS. 2 to 8 will be described below.

FIG. 2 is a partial side view of the article storage device according to this embodiment;
FIG. 3 is an overall plan view, FIG. 4 is a front view along the frontage of the storage shelf, and FIG. 5 is a perspective view of the main part.

This article storage device has 5 storage shelves 1a, 1b, IC
.

1d and 1e are arranged parallel to each other at intervals, and each storage shelf is provided with a large number of shelf booths 2 in the vertical and horizontal directions.

Each of these shelf booths 2 has a frontage 3 on both its front and rear ends,
Through these openings 3.3, articles can be taken in and out from either side.

Such shelf booths 2 are arranged in a row in the direction of the storage shelves 1, and each storage shelf 1 is a single storage shelf.

A narrow passage 4 is formed between each storage 11, and running rails 5 and guide rails 6 are installed at the bottom and top of the side passage 4 so as to be oriented in the longitudinal and longitudinal directions.

A stacker-type article loading/unloading 17 running in the narrow passage 4 along the running rail 5 is placed on the running rail 5 and is engaged with a guide rail 6.

This stacker 7 includes a main frame 8 that extends until it approaches the upper and lower rails 5 and 6 and has a built-in drive device.
The rental platform 9 is provided with a loading platform 11 equipped with a hook 10 that can perform a 1i return movement.

As shown in FIG. 2, one container 13 containing articles is stored in each shelf booth 2 of the storage a1.

These containers 13 have handles 14 protruding from both end faces corresponding to each frontage 3 of the shelf booth 2, and these handles 14.
．． It is exposed to 4.

Therefore, by moving the main frame 8 of the stacker 7 and moving the lifting platform 9 up and down, the loading platform 11 is positioned in front of the desired shelf space 2, and the hook 10 is attached to the handle 14 of the container 13 stored in the shelf space 2. By engaging the hooks 10 and retracting the hooks 10, the desired container 13 can be taken out onto the loading platform 11, and the container 13 on the loading platform 11 can be removed.
It is also possible to store it in the shelf booth 2 by pushing it with the hook 10.

Therefore, this loading and unloading can be performed using either of the stackers 7 located in the front and rear narrow passages 4 sandwiching the storage shelf 1.

For example, in FIG. 2, the container 13 stored in the storage 1111a can be taken in and out by the loading/unloading 97a or by using the loading/unloading machine 7b.

Further, for example, the loading/unloading unit 1fi7b can take in and out the containers 13 of the storage shelf 1a, and can also take out and take out the containers 13 of the storage shelf 1b.

The container 13 thus pulled out from the shelf space 2 of the storage shelf 1 onto the loading platform 11 of the stacker 7 is transported by the stacker 7 to the end of the narrow passage 4.

At the ends of every other storage shelf 1a, 1c, and Ie, an upper transfer conveyor 15u and a lower transfer conveyor 15 are arranged vertically, respectively, and the conveyors can move articles in the left and right direction, and the containers 13 Up to two can be installed.

An upper collection and delivery conveyor 22u is arranged in common contact with the upper transfer conveyor 15u and oriented in the front-rear direction, and similarly below the collection and delivery conveyor 22u, a lower stage is arranged in common contact with the lower transfer conveyor 15 and oriented in the direction of the building. Collection and delivery conveyor 22i
is located.

The part adjacent to each transfer conveyor 15u, 15* in the middle of the collection/delivery conveyor 22u, 221 is a branch conveyor 2.
0, and the containers 13 are being transferred between the transfer conveyors 15u and 15e and the collection and delivery conveyors 22u and 22 meals.

The branching conveyor 20 is equipped with a branching device 27 below the branching device 27, and the branching device 27 includes a pair of rotary belts 28 that are oriented left and right and are arranged in parallel in the front and back, and are supported so as to be able to move up and down. (See FIG. 5), the front and rear rotating belts 28 have a length rI420a after IyI of the branching conveyor 20.

20b so that it can protrude upward from the branch conveyor 20 or sink downward.

When the rotating belt 28 protrudes from the branching conveyor 20, the container can be moved between the collection and delivery conveyor and the transfer conveyor by placing the container on the rotating belt 28 and rotating it. By submerging the rotary belt 28 from the surface of the branch conveyor 20, the branch conveyor 20 becomes a conveyor continuous with the collection and delivery conveyor, and can transport containers back and forth.

An exit port 24 is located at the front end of the collection and delivery conveyor 22u, and the collection and delivery conveyor 22u is used exclusively for delivery, and conveys the container 13 from the rear toward the front to the exit port 24.

The lower collection/delivery conveyor 22 has an entrance 23 at its front end and is used exclusively for warehousing, and conveys the containers 13 rearward from the entrance 23.

A picking station 30 is provided at the rear ends of the collection and delivery conveyors 22u and 22u, and transfers the containers 13 between the upper and lower collection and delivery conveyors 22u and 22 fish.

The picking station 30 is a collection and delivery conveyor 22u.

22! It is a station provided on the left side in parallel to the top and is located at an intermediate height between both collection and delivery conveyors 22u and 22e, and is an inclined connection between the branch conveyor 2G provided at the end of the upper collection and delivery conveyor 22u and the picking station 30. A conveyor 31 communicates with the branch conveyor 20 and the picking station 30 provided at the end of the lower collection and delivery conveyor 22e, and an inclined connecting conveyor 32 connects them.

At the picking station 30, a part of the stored items in the container 13 is taken out and the container 13 is used when it is desired to return it immediately.
Container 13 arrives at picking station 30 on route 1
The container 13 is transported to the picking station 30, where the required stored items are taken out, and the container 13 is transferred to the connecting conveyor 32. The items are stored along the route of the upper collection and delivery conveyor 22u.

Looking at the movement in the case of normal unloading in this embodiment having the above-described mechanism, first, a predetermined container 13 is taken out from a predetermined shelf booth by the stacker 7, transported to the side of the upper transfer conveyor 15u, and then transferred to the stacker 7. 7, the container 13 is transferred to the upper transfer conveyor 15u.

The transferred Conchin 13 is placed in the upper transfer container 15u.
is carried to the upper stage collection and delivery conveyor 22u by the branching device 27, and is transferred to the upper stage collection and delivery conveyor 22u,
The upper collection and delivery conveyor 22u transports the goods to the outlet 24 and takes them out.

Conversely, in the case of storage, from the storage entrance 23 to the specified continuum 1
3 is conveyed by the lower collection and delivery conveyor 22 to a branching means 20 beside a predetermined lower transfer conveyor 15, and transferred to the lower transfer conveyor 15 by the branching device 21.

The container 13 filled with moss is transferred to the lower transfer conveyor 15.
z to the side of the storage shelf, transferred to a predetermined stacker 7, transported to a predetermined shelf booth, and stored in the same shelf booth.

Since the above-mentioned unloading and warehousing are performed using separate collection and delivery conveyors and transfer conveyors, simultaneous work is possible and efficient work is possible.

In addition, each storage unit 11 is a single type, and both end faces in the depth direction are the frontage, and the above-mentioned patent application filed by the applicant has
Similar to the article storage device of No. 9-268425, the container 13 can be taken in and taken out from either side.
In the figure, when containers 13 are taken out from the storage shelf 1a, two stackers 1a and 7b can be operated to take out the containers 13 from the storage shelf 1a. Enables efficient loading and unloading.

In addition, transfer conveyors 15u and 15* are installed on every other storage shelf, but the shelves that one transfer conveyor can hold are the shelves to which the transfer conveyor is attached and the shelves before and after it. There are a total of three rows of shelves, which is functionally equivalent to providing a transfer conveyor for each storage shelf and can maintain the operation of the loading/unloading machine.

Next, the control system in this embodiment will be explained.

FIG. 6 is a block diagram of the control system.

Reference numeral 51 denotes a management computer, which issues commands for storing and unloading goods, and is connected to an operation console 52, which includes a keyboard 53. CRT54, printer 55. Equipped with a floppy disk W156, it can receive necessary input from the keyboard 53 and display the operating status of the article storage device on the CRT 54, and if necessary print out the article storage status using the printer 55. You can also do that.

Further, the storage status of the article, etc. is recorded on the floppy disk by the floppy disk unit @56.

The management computer 51 constantly monitors the status of each stacker 7 and the upper and lower transfer conveyors 15u, 15, selects the operating order, and sends operating instructions together with necessary information to the main control panel 5.
Issued at 7.

Also, the management computer 51 is the host computer 50.
Online processing is also possible.

The main/sub@board 57 receives commands from the management computer 51, determines mutual operation procedures for each driving device based on the commands, and outputs operating signals to each control m+ board 58,60.

58 is a loading/unloading machine control panel, which controls the actual operation of each stacker 7.

60 is the collection and delivery fee m+ board, and the upper and lower collection and delivery conveyors 22u
, 22*, branching means 20. Upper and lower transfer conveyor 1
Controls the driving of 5u and 15n.

The above-mentioned control system performs the work of unloading and warehousing goods, and an example of the selection and work of the stacker 7 and upper transfer conveyor 15u during unloading will be explained based on the flowchart in FIG. do.

Here, store shelf 1 in order: Rs, R2, Rs.

R4, R5 and stacker 7 are S+, St, Ss.

84, Ss, Ss and upper transfer conveyor.

Us, Us and lower transfer conveyor L+, L3.

Label it as Ls.

First, the container 13 to be taken out is 1IRt in the odd row.

It is determined whether or not it is stored in Rs, Rs (step ■), and if it is stored in an odd column shelf, proceed to step ■; if it is stored in an even column shelf R2, R4, step ■ Pass through.

When proceeding to step ■, it is determined whether the upper transfer conveyor Uλ at the end of the odd-numbered shelf RL is already loaded with two containers 13 and is full, and if it is full, there is an empty space. When a space is available, it is determined whether the stacker SL along the frontage surface of the storage 411RL is in operation or not (step ■), and if the stacker SL is not in operation, the stacker SL removes the container. is transferred to the upper transfer conveyor UL (step ■),
Proceed to step ■.

If the same stacker SL is in operation in step ■, it is determined whether the next stacker SL+1 is in operation (
Step (2), if any of the stackers S=, S=+1 is in operation, steps (2) and (2) are repeated until the operation ends.

When it is determined in step ■ that the stacker Sλ+1 is not in operation, the stacker SL+1 transports the container to the upper transfer conveyor UL (step ■
), proceed to the step.

In step (2), the container 13 is moved to the end of the branching conveyor 20 by the upper transfer conveyor U=, and transferred to the branching conveyor 20 by the branching device 27. It is determined whether or not the process has ended (step ■), and if it has not ended, the process returns to step ■.

Next, the container 13 to be taken out in step
When it is at λ, the process proceeds to step (2), where it is determined whether the front upper transfer conveyor U, -1 is full or not, and if it is full, it is determined whether the next upper transfer conveyor Uλ+1 is full or not. (Step Co., Ltd.), both conveyors Uλ-1, j12+
If all 1s are full, wait until they become available.

If the upper transfer conveyor U=+1 is vacant in step [stock], the process proceeds to step ■, where it is determined whether or not the back stacker 32+i of the even-numbered shelf R= is in operation, and whether it is in operation or not. If the container is held until the end of operation, the same stacker SL+1 transports the container to the upper transfer conveyor lJ2+1 on the back side (step @), and transfers the container to the upper transfer conveyor Uλ+1.
The container is carried to the end of the branching conveyor 20 and transferred to the branching conveyor 20 by the branching device 21 (step @), and the process proceeds to step (2).

Also, if the upper transfer conveyor Uλ-1 is empty in step ■, the process proceeds to step ■, where it is determined whether or not the stacker SL in front of the even-numbered shelf Rλ is in operation, and if it is in operation, When the operation is completed, the stacker SL transports the container to the upper transfer conveyor UL-1 (step ■), and proceeds to step [stock].

In step [phase], the container is moved by the upper transfer conveyor U^-1 to the branch conveyor 20 Q=, and transferred to the branch conveyor 20 by the branch 5A position 27, and the process proceeds to step (2).

If there is no next task in step ■, finish the task.

All of the above unloading work is carried out on the upper transfer conveyor 15u.

Branch conveyor 20. This is done independently by the collection and delivery conveyor 22u and is not affected by the lower transfer conveyor 15 etc.

Next, the procedure of warehousing work will be explained based on the flowchart of FIG. 8.

First, when a container arrives at the storage entrance 23 (step [phase]), the management computer 51 knows the storage shelf where the container is to be stored, and in step .

It is determined whether it is of Rs.

There are two cases: the shelf on which the container arriving at the storage entrance 23 should be stored is determined from the beginning, and the optimal storage shelf is determined according to the storage situation. The computer 51 knows the storage shelf to be stored.

If it is determined that the storage shelf is an odd-numbered shelf Rλ in step ①, the process proceeds to step @, and the container is placed on the lower collection and delivery conveyor 2.
The two vessels transport the lower stage transfer conveyor to the adjacent branch conveyor 20, and the branch device 27 transfers it to the lower stage transfer conveyor L, and transports it to the end of the storage shelf Rλ (step [phase]).

Then, it is determined whether or not the stacker SL in front of the lower transfer conveyor LL is in operation (step [phase]). If it is not in operation, the process proceeds to step O, and the stacker S= moves the container to a predetermined shelf. Stored in the booth and step [
Proceed to phase].

Furthermore, if the stacker SL is in operation in step [phase], the process proceeds to step (2), where it is determined whether or not the next stacker SL+j is in operation, and which stacker S=, S
If =÷1 is also in operation, steps (2) and (2) are repeated until the operation is completed.

When the stacker SL+1 is no longer in operation in step 2, the process proceeds to step [phase], where the container is stored in a predetermined shelf booth by the stacker SL+1, and the process proceeds to step [phase], where it is determined whether or not all 2 operations have been completed. , if not completed, return to step [phase] again.

Next, when it is determined in step 2 that the storage shelf storing the container is the even-numbered shelf R^, the process proceeds to step [phase], and it is determined whether the lower transfer conveyor LL-1 in front of it is full or not. If it is full, the process proceeds to step [phase], and it is determined whether the next lower transfer conveyor L=+1 is full or not.

When any of the lower transfer conveyors LL-1, L, +1 is full, steps [phase] and [phase] are repeated to create an empty space.

If there is space on the lower transfer conveyor LL+1 in step [phase], the process proceeds to step [phase], and the container is transported by the lower collection and delivery conveyor 22 to the branch conveyor 20 adjacent to the lower transfer conveyor 12+1, and then by the branching device 27. Transferred to lower transfer conveyor LL+1, storage shelf Rλ+
It is carried to the first end (step ■).

Then, the container is stored a by stacker SL+1.
It is stored in a predetermined shelf booth of Rλ (step [phase]) and proceeds to step [phase].

If there is space on the lower transfer conveyor [λ-1] in step [phase], the process proceeds to step [phase], and the container is transferred to the branch conveyor 2 adjacent to the lower transfer conveyors 1 and -1 by the lower collection and delivery conveyor 221. It is transferred to the lower transfer conveyor LL+1 by the branching device 27, and is carried to the end of the storage shelf RL-1 (step @).

Then, the container is placed on the storage shelf R by the stacker SL.
It is stored in the designated shelf booth (step @), and the step [
phase].

If there is no next work in step [phase], end the work.

All the above warehousing work is carried out on the lower transfer conveyor 15! .

Branch conveyor 20. This is done independently by the collection and delivery conveyor 22, and the influence of the upper transfer conveyor 150, etc.
I don't accept it.

Therefore, even if there is a conflict between shipping and receiving, the tasks can be performed at the same time, greatly improving work efficiency.

In addition, in order to ensure that unloading and warehousing are independent and to shorten the working time of the stacker, when the stacker that has been moved to the upper transfer conveyor for unloading can be used for warehousing, we recommend using the same stacker for warehousing as much as possible. By doing so, wasted time for moving the stacker can be omitted, and work efficiency can be further improved.

As described above, even if the transfer conveyor is placed on every other storage shelf, the selection of the transfer conveyor and stacker to be used is optimally controlled, thereby suppressing cost increases and reducing the risk of movement of the transfer conveyor and stacker. It is possible to equalize the work efficiency of warehousing and warehousing.

Further, when taking out a part of the stored items in the container, the working time can be further shortened by using a picking station.

Note that if there is no work to take out a part of the container, or if the container is not used and the stored items themselves are transported as they are, a picking station is not necessarily necessary, and the picking station is simply used to transfer the stored items between the upper and lower collection and delivery conveyors. A lift-up conveyor may be installed to perform the change.

The present invention can greatly improve work efficiency by providing two stages of upper and lower transfer means and collection and delivery means.

Further, by providing a transfer means on every other storage shelf, increase in cost can be avoided.
