Then, after tracking and reaching the position of the sorting chute 23, a sorting signal is output to the driving device 37 facing the sorting chute 23 to sort the articles 4 to the target sorting chute 23.

In addition, inspection is executed at the time of sorting. That is, the articles 4 whose target sorting chute 23 cannot be specified, that is, the articles 4 picked by mistake, are discharged to the reject line (not shown), and the belt conveyor device 16
When the bar code data of the article 4 to be sorted into the sorting chute 23 has not been input to the sorting chute 23 in the previous batch when the drive signal of the The missing data is output to the cart controller 74.

When all the articles 4 in this batch have been sorted, the delivery conveyor 25 is driven to deliver the container 24 to the chute buffer line 27, and then the transfer device 30 is driven to remove the empty container 24. Sorting chute 23
Move to the position and wait.

The above operation is executed every time the batch number is input from the DPS controller 72. "Cart Controller 74" The operation of the cart controller 74 will be described.

When the batch number is input from the DPS controller 72, the information of the new order number for each sorting chute and each batch shown in FIG. Ask for a new order number.

Next, the picking cart information (FIG. 18) is retrieved from these new order numbers to obtain picking data, that is, the number of the sorting chute 23, the number of containers, the shelf number N, and the picking quantity for each new order number. At this time, when the number of containers is two or more, it is confirmed whether or not the number of containers and the packing number (branch number) of the new order number retrieved above match, and if confirmed, the picking work based on the picking data of the new order number. It is judged that it can be started, and a time difference is provided (for example, after a certain time such as after 5 minutes)
Then, it is put on the above-mentioned picking list {Fig. 8 (a)}.

When the out-of-stock data is input from the sorter controller 73, the number of the batch and the sorting chute 23 is searched for the information of the new order number for each sorting chute 23 and each batch shown in FIG. Find the new order number that occurred. Then, the item 4 of the out-of-stock data
The second picking frontage information is retrieved from the data of No. 2 to obtain the shelf number N of the frontage 45 storing the article 4, data including the rack number N and the picking quantity is formed, and the picking of the obtained new order number is performed. Append to data. As a result, the missing item 4 is complemented in the picking cart facility Z.

Further, the picking list data is transmitted to the picking cart 41 via the wireless communication device 44. In addition,
The order number (old number) that determines that the picking work can be started first is put on the upper part of the picking list (the new order number is added at the end), so the order for the container 24 at the tip of the shoot buffer line 27 is received. Numbers are displayed with priority.

Next, when selection data (to be described later) of the order number selected based on the picking list is input from the picking cart 41 via the wireless communication device 44, the picking data of the order number (including the order number is included. ) Is transmitted to the picking cart 41 via the wireless communication device 44.

When picking end data (to be described later) including the order number is input from the picking cart 41 via the wireless communication device 44, the picking data of the order number is deleted. "Controller 65 of Picking Terminal 59 of Picking Cart 41" The operation of the controller 65 of the picking terminal 59 will be described.

As an initial screen, the picking list {FIG. 8 (a)} received from the cart controller 74 via the antenna 66 and the wireless communication device 64 is displayed on the liquid crystal display 62.
Display to.

Subsequently, the order number data at the position detected by operating the touch panel 63 is transmitted to the cart controller 74 as the order number selection data via the wireless communication device 64 and the antenna 66.

In response to this transmission, the cart controller 74
When picking data (including the order number) is received via the antenna 66 and the wireless communication device 64 from FIG.
As shown in, the liquid crystal display 62 displays the order number, the number of the sorting chute 23 and the number of containers 24, and the work data for performing the picking work, that is, "the shelf number N of the frontage 45 and the number of the articles 4 to be picked". Display the "Inspection" switch and "End" switch. Picking work is started by this display.

Next, the bar code data of the label 46 of the frontage 45 where the article 4 is picked by the bar code reader 61
If you enter (corresponds to the shelf number N), it is confirmed whether this data matches the above work data, and when confirmed, the confirmed work data is deleted (note that the number of picking quantities and the barcode data are Shall be entered). If it is wrong, an error is displayed on the liquid crystal display 62 to warn of the mistake.

When it is confirmed that all the work data have been erased, the label printer 60 is made to output the number of shipping labels 67 obtained by adding 1 to the number of containers. As the data to be printed on the shipping label 67, the above-mentioned order number is used by the label printer 60.
Send to.

When the operation of the position of the "end" switch is confirmed after confirming that all work data has been erased, picking end data including the order number is transmitted to the cart controller 74 via the wireless communication device 64 and the antenna 66. To do. "Operation" The operation of the picking operation with the above configuration will be described. 1. When the order information is input to the pre-picking order receiving computer 71, the order receiving computer 71 forms DPS information, sorter information, and picking cart information.
Information is output to the DPS controller 72, the sorter controller 73, and the cart controller 74, and the new order number information for each sorting chute and each batch shown in FIG. 14 is formed. This information and the second picking shown in FIG. The frontage information is output to the cart controller 74. These pieces of information are stored in the respective controllers 71, 72, 73. 2. Digital picking equipment X and sorter equipment Y
The picking work DPS controller 72 in 1 turns on the frontage indicator 2 of the frontage 6 for picking one batch, and causes the worker to execute the picking work for one batch. At this time, the number of the batch being executed is output to the sorter controller 73 and the cart controller 74.

The picking operator has a frontage 6 for picking.
When the picked quantity is displayed on the frontage indicator 2 and the display / completion button 13 is lit, the picking quantity of the articles 4 is picked from the frontage 6 according to the display of the frontage indicator 2 and the belt conveyor device 16 The article 4 is directly placed so that the bar code of the article 4 is on the top, and the display / completion button 13 is pressed. The DPS controller 72 displays this display / completion button
When the input of 13 is confirmed, the frontage indicator 2 is turned off, and when the completion of the picking work of all the frontages 6 is confirmed, the belt conveyor device 16 is driven to convey the loaded article 4 to the sorter facility Y. After the certain period of time, the DPS controller 72 causes the front end 6 to perform picking for the next batch.
The frontage indicator 2 is turned on.

The sorter controller 73 specifies the sorting chute 23 that sorts the articles 4 based on the sorter information based on the input batch number. At this time, the number of sorting chutes 23 specified is half. Then, when the article 4 is conveyed by the belt conveyor device 16 and the bar code data is inputted from the bar code reader 17, the article 4 is discriminated by the bar code data and sorted into the target sorting chute 23. This sort chute
The articles 4 sorted by 23 are put into a container 24 that is automatically supplied.

Further, the inspection in the sorter equipment Y is executed. That is, the article 4 in which the target sorting chute 23 is not found is conveyed to the reject line (not shown), whereby the article 4 picked by mistake is eliminated, and the article 4 sorting to the sorting chute 23 is completed at the end of the batch. When it is not conveyed, the lacking-item data corresponding to the missing item 4 is formed and output to the cart controller 74.

When the sorting of this batch is completed, the payout conveyor 25 is driven to dispense the sorted containers 24 to the chute buffer line 27 and store them in the chute buffer line 27. By storing in this manner, one sorting chute 23 can handle a plurality of batches, that is, a plurality of sorting destinations. Subsequently, the transfer device 30 is driven to supplement the sorting chute 23 with the container 24.

Thus, when sorting is performed for each batch, as can be seen from the sorter information, half of the sorting chutes 23 are used for sorting one batch, and as shown in FIG. The sorting chutes 23 are used alternately. Therefore, the container 24 can be taken out from the chute buffer line 27 whose sorting is suspended, and even while the container 24 is taken out, the sorter device 21
It is possible to continue picking work without stopping. The containers 24 having the same order number stored in the chute buffer line 27 are sorted into the same sorting chute 23 as shown in FIG. 20 (see the order number for each sorting chute 23 and each batch shown in FIG. 14). 3. The picking work cart controller 74 in the picking cart facility Z uses the input batch number to picking data for each order number based on the picking cart information and the order number for each batch, that is, the number of the sorting chute 23, the number of containers, and the shelves. Number N
And the picking quantity are calculated with a time lag (for example, 5
After a minute), the picking list is placed on the picking list, and the data of the picking list is transmitted to the picking cart 41 via the wireless communication device 44. When the number of containers is 2 or more, it is confirmed whether the number of containers and the packing number of the retrieved order number match, and when confirmed, it is put on the picking list. Items to be replenished based on the input missing data 4
Is added to the picking data. The time difference absorbs the time difference between the work in the digital picking equipment X and the sorter equipment Y and the work in the picking cart equipment Z.

At the start of the work, the operator of the picking cart 41 selects the leading order number from the picking list on the initial screen and operates the touch panel 63. Then, the selection data of the order number is transmitted to the cart controller 74, and in response, the order number, the number of the sorting chute 23 and the number of containers 24, and the work data for performing the picking work, that is, ““ The shelf number N of the frontage 45 and the quantity of the picked article 4 are displayed, and the "inspection" switch and the "end" switch are displayed. By selecting the first order number (the old number above) from the picking list, the order number of the container 24 at the tip of the chute buffer line 27 (the order number that requires the fastest picking work) Is preferentially selected.

Next, the operator of the picking cart 41 moves the picking cart 41 to the sorting chute 23 of this number based on the number of the sorting chute 23, and the number of containers 24 of the number of containers displayed from this sorting chute 23. Is taken out, the contained article 4 is transferred to the collection container 54, and the empty container 24 is placed on the container return line 28. The empty container 24 is transferred to the empty container supply device 26 through the container return line 28, and the empty container supply device 26 waits for each sorting chute 23 (position of the transfer device 30).
Be transported to.

Next, the worker of the picking cart 41 picks the picked quantity of the article 4 of the work data from the frontage 45 of the shelf number N of the work data and puts it into the collection container 54.
Bar code reader from the bar code label 46 of this frontage 45
Use 61 to read the barcode data a number of times the picking quantity. By this operation, the picked article 4
Is inspected, and when it is normal, the "Inspection" switch lights up,
The executed work data is deleted. Picking cart 41
The operator confirms the lighting of the inspection switch and the erasure, and continues the picking work based on the next work data. It is to be noted that the number of the collection containers 54 for storing the articles 4 including the articles 4 from which the containers 24 are taken out is required to be the number obtained by adding 1 to the number of containers.

When the picking work based on the work data is completed, the cart controller 74 issues the number of shipping labels 67 obtained by adding 1 to the number of containers by the label printer 60. The operator of the picking cart 41 attaches these shipping labels 67 to the collection container and operates the “end” switch. As a result, it is determined that the work of the order number for which this picking is executed is completed, and the initial screen is displayed on the liquid crystal display 62.

Next, the operator of the picking cart 41 moves to the shipping area, wholesales the collection containers 54, and selects the next order number on the initial screen to start the next picking operation.

The worker of the picking cart 41 first transfers the article 4 from the container 24 of the sorting chute 23 to the collecting container 54. However, the worker performs the picking work based on the work data first, and then Alternatively, the articles 4 may be transferred from the container 24 of the sorting chute 23 to the collection container 54.

In this way, the articles (articles of order information) 4 to be sorted are sent to the first picking shelf 1 (digital picking equipment X and sorter equipment Y) and the second picking shelf 43 (picking cart equipment Z) for each shelf frontage information { Figure 10
