The control circuits K ₁ to K ₅ for each shelf may have the same configuration as the control circuit used in conventional electric movable shelves; It is most preferable to use the control circuit disclosed in the specification and drawings of the above. From the local circuits LO ₁ to LO ₅ of each shelf, each control circuit K ₁ to K ₅
The signals applied to the external operation contacts Rm ₁ to Rm ₅ of the movable shelf operation switches SW ₁ to Rm 5 of each shelf are
It is assumed that the signal is the same as the signal applied by the operation of SW ₅ , and that it is processed in the same way.

Next, the operation of the present invention will be explained.

Computer CMP has an inventory management function,
It receives and organizes the input/output data and sends it to the microcomputer MC via the interface IN. Interface IN controls data communication between computer CMP and microcomputer MC. The microcomputer MC receives data from the computer CMP and sends data to each local circuit LO 1 to LO ₁ through the mobile shelf interface DIN.
In addition to sending data such as location, quantity, and storage/output to LO ₅ , interlocking signals are sent to control circuits K1 to _K5 of each shelf ₁₀₁ to 105 from their contacts _Rm1 to _Rm5 . There is. The microcomputer MC also monitors the start command switches NX1 to NX5, re-operation switches RE1 to RE5, and safety bar switches CA1 to CA5 installed on each mobile shelf, and after confirming the operation of the switches, performs the following processing. Do this. That is, after inputting the storage/output information, a signal is input to the control circuit of the shelf corresponding to the first location according to a predetermined order based on the location data, and a signal is input to the control circuit of the shelf corresponding to the first location in a predetermined order based on the location data. 101 and the shelf 102). Entering this passage, goods are loaded and unloaded according to the data input to the computer CMP, and then a start command switch (switch NX1 or NX2 in the above example) on that shelf is activated.
When pressed, the next necessary work passage is formed based on the entry/exit data input into the computer CMP. This is because when the input/output data is input into the computer CMP, the data is organized and the first work passage to be formed and the second, third, etc. work passages to be formed are determined.
When the start command switch is pressed after loading and unloading work in the passage formed based on this, the signal is transmitted to the computer CMP, and the computer CMP
In response to this, a signal is input to the control circuit of the shelf corresponding to the position where the passage is to be formed next, and that shelf is moved. As for the order in which the passages are formed one after another, shelves 101 and 1
between shelves 102 and 103, between shelves 103 and 1
The order may be between 04 and 04, or the reverse order may be used. In addition, since two movable shelves face each other in the same work passage, and each shelf has multiple frontages, stages, and blocks, the data of 1 input to the computer CMP and other Depending on the data, the passage may be common. In that case, even if one of the start command switches NX1 to NX5 is operated, the shelf will not move, and articles can continue to be loaded and unloaded within the aisle. In the created aisle, one of the display panels Pr ₁ to Pr ₅ displays the previously input entry/exit data corresponding to that aisle, so goods can be transported according to the display on the display panel. You can enter and exit the warehouse. The original purpose of the safety bar switches CA1 to CA5 is to activate when a worker, etc. in the aisle comes into contact with the shelf while it is moving, to stop the movement of the shelf, and to ensure the safety of the worker, etc. , after the passage is formed, it is useless until the shelf starts moving again according to a predetermined command. Therefore, in the embodiment of the present invention, once the passage is formed, the safety bar switches CA1 to CA5 are also used as carry switches for the displays on the display panels _Pr1 to _Pr5 . That is, if the safety bar switch in that passage is pressed when the display board of the passage cannot display the predetermined data all at once, the remaining data will be displayed on the display board. Of course, a carry switch may be provided independently in addition to the safety bar switch. If the passage is not formed correctly due to the operation of safety bar switches CA1 to CA5 while moving the shelves, press the re-operation switch RE1.
- Operate one of RE5. As a result, the signal for forming the passage is inputted again, and the passage forming operation is performed again based on this signal.

Next, based on Figure 5, the microcomputer MC
The operation will be explained in detail. micro computer
The MC is programmed to perform the following operations.

1 Perform initial setting of each circuit as a preparatory operation.

2. Send blank data to each control board with indicator light of each local circuit LO ₁ to LO ₅ to make each display device non-display.

3 Check whether the test switch is on.
If it is on, it will run a pre-prepared self-diagnosis test program to find the location of the failure. If it is off, proceed to 4.

4 Transfer data from computer CMP. This data transfer is performed as shown in FIG. In Figure 6, RQ output from microcomputer MC,
The CALL signal "1" is input to the computer CMP, and in response, the CALL signal "1" is output from the computer CMP. The microcomputer MC uses this signal to confirm that the signal has been output from the computer CMP, and
The output signal is set to "0". Next, by outputting the preparation signal READY from the microcomputer MC, the computer CMP
Signals DC0 to DC7 are output. The microcomputer MC uses DC0 to DC based on the rising signal BUSE from the computer CMP.
After confirming the signal No. 7, the READY signal is set to "0", and further, based on the ACK signal from the computer CMP, the computer outputs the data as the first data.
Read the DC0 to DC7 data signals from the CMP. Next, from the computer CMP, the second
A second CALL signal is output as a prelude to the data transfer, and the microcomputer MC reads the second data in the same manner as described above. Figure 7 shows the data read in this way as a count sequence. 3-1-2
-03 is transferred, and these three data are separated by a start mark and an end mark of a predetermined code. In this example, information on quantities and warehouse receipts/issues is omitted, but such data may be handled as necessary.5 Organize the data transferred from the computer CMP. Based on the data blocks transferred by the method shown in FIGS. 6 and 7, S(K), D
Create an area (k, i) and enter each piece of data. k corresponds to the aisle number, i
corresponds to the data number in that passage. That is, the three data blocks mentioned above are 1
-3-3-12, 1-5-1-03, 3-1-2-
03, data exists in the number 1 and 3 paths, and number 1 data and number 2 data exist in the number 1 path. Also, S(K) in Figure 8
Area K indicates a passage, and the number of data in each passage is entered for each passage. Therefore, the illustrated example shows that the data in the first passage is 2 and the data in the third passage is 1. M in Figure 8
indicates the area where the entry/exit information is entered; "1" is entered for entry, and "0" is entered for exit. Therefore, the illustrated example indicates that the item is in stock. Data is organized as described above.

5. Check the safety bar switches CA1 to CA5 and the movable shelf operation switches _SW1 to _SW5 . Its individual operations are as follows.

6-1 Check whether there is data S(K) for that path.

6-2 When data S(K) is received, that is,
When S(K) is not 0, the first display data, that is, the data of i=1, is sent to the next 6-3.

6-3 Send display linked data to passage k.

6-4 Check whether switches CA1 to CA5 are on or off, and if any of the switches CA1 to CA5 is on, go to 6-5 and turn on the switch.
6-6 if all CA1 to CA5 are off
go to.

6-5 Check whether S(K)>i, that is, whether there is an undisplayed item other than what is currently displayed. If there is, go to 6-7; if not, go to 6-6.

6-7 Increase data number i by one, 6-
Return to 3.

6-6 If the re-operation switches RE1 to RE5 are on, the process goes to 6-9, where the interlocking command is temporarily stopped and the interlocking data is sent again from 6-3.

6-8 If the re-operation switches RE1 to RE5 are all off, come here and turn on the start command switch.
Check whether NX1 to NX5 are on. If it's on, go to 6-10, if it's off, go back to 6-4. Switch NX1~
If NX5 is on, go to 6-10 and S
Confirm that (K)=i, that is, all the displays have finished, and if so, go to
Open a loop with k=1 to 5. Also, switch
6-4 again when NX1 to NX5 are off
Go to and form a loop again. Even when S(K)=i does not hold in 6-10, the switches NX1 to NX5 are ignored and the process goes to 6-4.

The above is the operation of the microcomputer MC.

FIG. 9 shows data transfer from the microcomputer MC to the local circuits LO ₁ to LO ₅ of each shelf. Signals such as those shown in FIG. 9 are constantly sent to each local circuit LO ₁ to LO ₅ . Therefore, which local circuit the data is connected to
It is necessary to select data from LO ₁ to LO ₅ . The signal for this is included in the "passage" part in Figure 9, and the SYNC1 signal is "1", and the SYNC1 signal is "1".
When the signal No. 2 is "0", it indicates the passage number. Figure 9 shows that among the three data mentioned above, each number of aisle, frontage, step, and block is 1.
-3-3-12 is shown. and,
In this time chart, each location is read at the rising edge of the CLOCK signal, and as mentioned above, when SYNC1 is "1" and SYNC2 is "0", the aisle number is read, and SYNC1 is used for entering and exiting the warehouse. It is set to read when SYNC2 is "1".

First, check to see if there is an aisle number. In this example of the time chart, the passage number is 1, indicating that passage numbers exist. Next, the frontage number is "1" for DL1 and "1" for DL0.
Because of this, the 3rd frontage and step number are as follows.
Since DL1 is "1" and DL0 is "1",
You can see that it is the third stage. The block number is divided into the 10's place and the 1's place. First, the 10th place is 1 because DL0 is "1", and the 1's place is 1 because DL1 is "1". "in
Since DL0 is "0", it is 2, which means it is the 12th block. Further, although not shown, the inventory quantity can also be expressed using a similar time chart.

Each local circuit LO ₁ to LO ₅ identifies the data to be transferred as described above, and when the aisle number corresponds to the aisle number to be formed between that shelf and an adjacent shelf, that local circuit sends a signal to the control circuit of the shelf through one of the contacts Rm ₁ to Rm ₅ , and according to this signal, a passage is formed at a predetermined position.

Frontage numbers, stage numbers, etc. are displayed on the display boards Pr ₁ to Pr ₅ in the passageway thus formed, so it is only necessary to enter and exit the warehouse according to these displays. However, depending on the input data, one display board in that aisle may not be able to display all the data related to that aisle. Press the safety bar switch at At this time, if there is undisplayed data, it will be displayed on the display panel.

FIG. 10 shows a time chart when switch CA1 is pressed in passage 1. As shown in Figure 10, the aisle number is sent when SYNC1 is "1" and SYNC2 is "0", and SYNC1 and
When SYNC2 is both "0", the REPEAT, NEXT, and CARRY data in the selected path are read by the microcomputer. Here, REPEAT is the signal of the re-operation switches RE1 to RE5, and NEXT is the signal of the start command switch NX.
The signals 1 to NX5, CARRY, correspond to the signals of the safety bar switches CA1 to CA5.
In this case, as indicated by x in Figure 10,
Before SYNC1 became "1" and SYNC2 became "0",
That is, even if the switch CA1 is operated and a carry signal is issued before the passage number data is read by the microcomputer MC, the data at this time will not be read by the microcomputer MC. Therefore, since the signal is received only from the switch in the selected passage, even if another person operates the switch in another passage, the movable shelf will not operate, thereby improving safety.

FIGS. 11 to 15 are flowcharts of the inventory management program.

In FIG. 11, steps 1 and 2 start and prepare, and step 3 displays the title and requests an on-input. Input the data in step 4, and judge whether the data is correct in step 5. If it is correct, go to step 6, otherwise go back to step 4. At step 6, the data is transferred to memory A, and at step 7, the presence or absence of the data is checked.
If there is data, go to 8, otherwise go to 15,
At step 16, a password is entered, and at step 17, the password is set. Next, new data is input at steps 18 and 19, and data is created at step 20. If the data is found in step 7, the password is input in steps 8 and 9, and it is determined in step 10 whether the passwords match. If the passwords do not match, go through 21 and return to 9 again. In step 21, the password mismatch is displayed and the user is requested to enter the password again. If the passwords match in step 10, the desired menu is set in steps 11 and 12. 11 inputs warehousing data, warehousing data, and prints out the list.

In FIG. 3, if the flowchart in FIG. 11 is specified, the title is displayed and a request is made to input the stock number and number of items out in step 34.
At step 35, input is made according to the request. At 35, check if there is a corresponding number, and if there is, go to 37.
If there is not, a message to that effect is displayed at 44 and an input request is displayed, and the process returns to 35. In step 37, compare the current number of items in stock and the number of items out, and in 38, determine whether or not you are trying to issue more than the number in stock.If you are trying to issue more than the number in stock, in 45, adjust the number of items out to within the number in stock. Then, in step 46, the display indicates that the number of stocks is insufficient, the corresponding stock number, product name, and number of items out of stock are displayed, and a data confirmation input request is displayed. 38
If it is found in step 39 that the item is to be shipped within the stock quantity, the corresponding inventory number, item name, and number of items to be shipped are displayed in step 39, and a data confirmation input request is displayed. At 40, input according to the request,
At 41, it is determined whether the input is correct, and if it is correct, the process goes to 42, and if it is incorrect, the process goes back to 34. At step 42, the location and number of items out of the stock number are stored in memory B, and at step 43, the data of the stock number is corrected. Note that when a predetermined signal Q is input at 35 or 40, the data in memory B is rearranged in the order of location at 47, and the data stored in memory B is outputted to the microcomputer MC at 48, and the process goes to.

FIG. 14 is a flowchart for printing out a list. In this flow, either a list output of all items or an output of items divided from the appropriate inventory is selected and displayed on the printer. . In FIG. 14, when the flowchart in FIG. 11 is specified, a title is displayed, a list is displayed, and a list selection input request is performed in 49. The details of the list selection input request are 1. List output of all items, and 2. Output of items divided by appropriate inventory. In step 50, one of the outputs 1 and 2 is specified. If the specified message is other than 1 or 2 above, an input error message is displayed and a re-input request is made at 51, and the process returns to 50. When 1 is specified in 50, a request for inputting an output range instruction is made in 52, and an instruction according to the request is made in 53. At step 55, the command at step 53 is analyzed, and if there is an input error, an input error is displayed at step 54, and the process returns to step 53. If the analysis at 55 is for each item, printing is performed for each item at 56, and if the analysis at 55 is for each block, printing is performed for each block at 57. Further, when 2 is specified in 50, printouts are performed in units of blocks or in units of items for items obtained by dividing the appropriate inventory according to a flow completely similar to the above-described flow.
