The containers 13 are stored through the route of the connecting conveyor 32 and 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, the stacker 7 moves the container 13 from a predetermined shelf booth to a predetermined container 13.
is taken out and conveyed to the side of the upper transfer conveyor 15u, and the container 13 is transferred to the upper transfer conveyor 15u by the stacker 7.

The transferred container 13 is transported to the upper collection and delivery conveyor 22u by the upper transfer container 15u, and is transferred to the upper collection and delivery conveyor 22u by the branching device 27, and then transferred to the upper collection and delivery conveyor 22u by the branching device 27.
The products are then transported to the exit 24 and exited from the warehouse.

Conversely, in the case of storage, the predetermined content 13 is transferred from the storage entrance 23 by the lower collection and delivery conveyor 22l to the branching means 2 beside the predetermined lower transfer conveyor 15l.
0 and transferred to the lower transfer conveyor 15l by the branching device 27.

The transferred container 13 is carried to the side of the storage shelf by the lower transfer conveyor 15l, 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 shelf 1 is a single type, and both end faces in the depth direction are the frontage, and the present applicant has already filed Japanese Patent Application No. 59-268425 (Japanese Unexamined Patent Publication No. 61-150907).
As with the article storage device, containers 13 can be taken in and taken out from either side. For example, in FIG. Since the container 13 can be operated and taken out from the storage shelf 1a, it is possible to efficiently take the container 13 in and out of the storage shelf 1a.

In addition, the transfer conveyors 15u and 15l are on storage shelf 1.
They are installed at every other storage shelf, but each transfer conveyor can handle a total of three rows of shelves: the shelf to which the transfer conveyor is attached and the shelves before and after it. It is possible to maintain the operation of the loading/unloading machine functionally equivalent to one equipped with a loading/unloading conveyor.

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 warehousing and unloading of goods, and is connected to an operation console 52, which includes a keyboard 5.
3. It is equipped with a CRT 54, a printer 55, a floppy disk device 56, and a keyboard 53.
The operating status of the article storage apparatus can be displayed on the CRT 54 by receiving necessary input from the apparatus, and when necessary, the article storage status can also be printed out using the printer 55.

In addition, the storage status of articles and the like are recorded on a floppy disk by a floppy disk device 56.

The management computer 51 constantly monitors the status of each stacker 7 and the upper transfer conveyors 15u, 15l, selects the operating order, and issues operating instructions to the main control panel 57 along with necessary information.

Further, the management computer 51 can perform online processing using the host computer 50.

The main control panel 57 receives commands from the management computer 51, determines mutual operation procedures for each drive device based on the commands, and sends operation signals to each control panel 58,
Output to 60.

58 is a loading/unloading machine control panel, and each stacker 7
control the actual behavior of

A collection and delivery control panel 60 controls the driving of the upper and lower collection and delivery conveyors 22u and 22l, the branching means 20, and the upper and lower transfer conveyors 15u and 15l.

The above-mentioned control system performs the work of unloading and receiving goods, and an example of the selection and work of the stacker 7 and the upper transfer conveyor 15u during unloading is based on the flowchart in FIG. explain.

Here, store shelves 1 in order R ₁ , R ₂ , R ₃ , R ₄ , R ₅
and stacker 7 as S ₁ , S ₂ , S ₃ , S ₄ , S ₅ , S ₆ , upper transfer conveyor as U ₁ , U ₃ , U ₅ and lower transfer conveyor as L ₁ , L ₃ , L ₅ Sign.

First, the container 13 to be taken out is an odd row of shelves R ₁ ,
It is determined whether or not the item is stored in R ₃ and R ₅ (step), and if it is stored in an odd column shelf, the process advances to step, and it is determined that the item is stored in an even column shelf R ₂ and R ₄ . If so, proceed to step.

When you advance to a step, the shelf in that odd row
It is determined whether the upper transfer conveyor Ui at the end of Ri is already loaded with two containers 13 and is full, and if it is full, waits until a space becomes available.
When a space becomes available, it is determined whether or not the stacker Si along the opening surface of the storage shelf Ri is in operation (step). If the stacker Si is not in operation, the stacker Si moves the container to the upper transfer conveyor. Transfer to Ui (step) and proceed to step.

If the same stacker Si is in operation in step, it is determined whether the next stacker Si+1 is in operation (step), and which stacker
If Si and Si+1 are also in operation, repeat step 2 and wait for the end of operation.

If it is determined in step that the stacker Si+1 is not in operation, the container is transferred to the upper transfer conveyor Ui by the stacker Si+1 (step), and the process proceeds to step.

In step, the container 13 is moved to the end of the branching conveyor 20 by the upper transfer conveyor Ui, and transferred to the branching conveyor 20 by the branching device 27, and the work of moving the container up to the branching conveyor 20 is completed for all requests. It is determined whether or not the process has been completed (step), and if it has not been completed, the process returns to step again.

If the container 13 to be taken out in the next step is on the even-numbered shelf Ri, proceed to the step,
It is determined whether the front upper transfer conveyor Ui-1 is full or not, and if it is full, the next upper transfer conveyor Ui-1 is
It is determined whether Ui+1 is full (step),
If both conveyors Ui-1 and Ui+1 are full, wait until they become empty.

If the upper transfer conveyor Ui+1 is empty in the step, the process proceeds to the step, and it is determined whether or not the back stacker Si+1 of the even-numbered shelf Ri is in operation. The container is transferred to the rear upper transfer conveyor Ui+1 using the stacker Si+1 (step),
The container is carried to the end of the branching conveyor 20 by the upper stage transfer conveyor Ui+1 and transferred to the branching conveyor 20 by the branching device 27 (step), and the process proceeds to the above-mentioned step.

In addition, if the upper transfer conveyor Ui-1 is empty at the step, the step advances to the even-numbered shelf.
It is determined whether or not the stacker Si in front of Ri is in operation. If it is, it waits for the operation to end and the container is transferred to the upper transfer conveyor using the same stacker Si.
Transfer to Ui-1 (step) and proceed to step.

In the step, the container is moved to the end of the branching conveyor 20 by the upper transfer conveyor Ui-1, transferred to the branching conveyor 20 by the branching device 27, and then the process proceeds to the step.

If there is no next task in a step, the task ends.

All of the above unloading work is carried out on the upper stage transfer conveyor 1.
5u, the branch conveyor 20, and the collection/delivery conveyor 22u, and are not affected by the lower transfer conveyor 15l, etc.

Next, the procedure for warehousing work will be explained based on the flowchart shown in FIG.

First, when a container arrives at the storage entrance 23 (step), the management computer 51 knows the storage shelf where the container is to be stored, and in step, the storage shelf is the odd-numbered shelf R ₁ ,
It is determined whether they belong to R ₃ or R ₅ .

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

If it is determined in step that the storage shelf is an odd-numbered shelf Ri, the process proceeds to step, and the container is transported by the lower collection and delivery conveyor 22l to the branching conveyor 20 adjacent to the lower transfer conveyor Li, and then transferred to the lower transfer conveyor 27 by the branching device 27. It is transferred to the conveyor Li and carried to the end of the storage shelf Ri (step).

And the stacker in front of the lower transfer conveyor Li.
It is determined whether or not the stacker Si is in operation (step), and if it is not in operation, the process proceeds to step 〓〓, where the container is stored in a predetermined shelf booth by the stacker Si, and the process proceeds to step 〓〓.

Also, if the stacker Si is in operation at step 〓〓, it is determined whether the next stacker Si+1 is in operation or not, and if both stackers Si and Si+1 are in operation, step
Repeat 〓〓 and wait for the operation to finish.

When the stacker Si+1 is no longer in operation at step 〓〓, the process advances to step 〓〓, where the stacker Si+1 stores the container in a predetermined shelf booth. and if it has not finished, return to step again.

Next, when the step determines that the storage shelf storing the container is the even-numbered shelf Ri, the process proceeds to step 〓〓, and the lower transfer conveyor Li in front of
1 is full or not. If it is full, the process advances to step 〓〓, and it is determined whether the next lower transfer conveyor Li+1 is full or not.

If both lower transfer conveyors Li-1 and Li+1 are full, steps 〓〓〓〓〓〓〓 are repeated until a space becomes available.

If there is space on the lower transfer conveyor Li+1 at step 〓〓, the process proceeds to step and the container is transported by the lower collection and delivery conveyor 22l to the branching conveyor 20 adjacent to the lower transfer conveyor Li+1, and then transferred to the lower transfer conveyor Li+1 by the branching device 27. and transported to the end of storage shelf Ri+1 (step).

Then, the container is stored in a predetermined shelf booth of the storage shelf Ri by the stacker Si+1 (step), and the process proceeds to step 〓〓.

In addition, if there is space on the lower transfer conveyor Li-1 at step 〓〓, the process proceeds to step 〓〓, and the container is transferred to the lower transfer conveyor Li-1 by the lower collection and delivery conveyor 22l.
It is conveyed to the branching conveyor 20 adjacent to Li-1, transferred to the lower transfer conveyor Li+1 by the branching device 27, and conveyed to the end of the storage shelf Ri-1 (Step 〓〓).

Then, the container is stored in a predetermined shelf booth of the storage rack Ri by the stacker Si (step 〓〓),
Proceed to step 〓〓.

If there is no next task at step 〓〓, end the work.

All of the above warehousing work is carried out on the lower transfer conveyor 15.
This is carried out independently by a branch conveyor 20, a collection and delivery conveyor 22l, and an upper transfer conveyor 1.
It is not affected by 5u etc.

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 reduce the working time of the stacker, when the same stacker that has been moved to the upper transfer conveyor for unloading can be used for warehousing, the same stacker is used as much as possible for warehousing. 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 the increase in cost and equalizing the movement status of the transfer conveyor and stacker. It is possible to improve the work efficiency of warehousing and warehousing.

Further, when taking out some 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, but simply picks the stored items between the upper and lower collection and delivery conveyors. A lift-up conveyor may be installed to perform the transfer.

Furthermore, regarding the upper and lower transfer conveyors and collection/delivery conveyors, the upper stage was used for unloading and the lower stage was used for warehousing, but conversely, the upper stage may be used for warehousing and the lower stage for warehousing. In this case, the above-mentioned embodiment When using a picking station such as this, the connecting conveyor may be configured to be able to drive itself.

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

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