Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a digital picking system used in fields such as distribution and physical distribution. Usually, there is an inspection process as a process subsequent to the picking process, and picking is performed as instructed in the inspection process. I am checking if there is any, but it relates to the method of deleting or reducing the inspection process.

[0002]

2. Description of the Related Art Currently, a generally used inspection method in a digital picking system is, for example, in a case where picking is carried out in a picking unit, for example, in a unit of a recipient, and then shipped, a storage box corresponding to a recipient in a picking process. It is a method in which the shipping slip is put in and placed, and the worker checks the instruction content and the number of instructions written on the actual item and the slip in the inspection process, and in the case of an information system,
A control number or a barcode corresponding to the control number is attached to the storage box, and the operator inputs the control number by key in the inspection process or reads it with a barcode reader, and then attached to the target item. There is a method to read all barcodes individually.

In any of the above conventional methods, an inspection process is required, and a large number of inspection workers must be put in. In addition, although the number of picking mistakes is significantly reduced, there are various problems such as the fact that all the inspection work must be performed by the operator in the subsequent inspection process.

[0004]

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned conventional problems all at once, and provides a false picking tracking method capable of deleting or reducing the inspection process in a digital picking system. It is something to try.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned points of view. In the picking process, a picking number instruction display function and a stock number of each item after picking ( Or, when it is found that there is no difference between the function to display the remaining quantity) and the indicated stock quantity (or the indicated quantity) and the actual stock quantity (or the actual quantity), the confirmation signal is sent to the host system. The function of notifying and the actual inventory quantity (or the actual inventory quantity) when the difference is found
The digital display for erroneous picking tracking, which has a function to correct the above and a function to notify the host system of the corrected stock number (or the remaining number), and the digital display is installed for each item to be picked. It seeks to provide a false picking tracking method.

[0006]

Next, the work flow and the essence of the principle of the false picking tracking method of the present invention will be described in detail. The normal operation of the conventional digital picking system is to pick the product as instructed for each picking unit, for example, each recipient,
When packing in a box, the worker in the picking process picks up the indicated number of products whose digital display lamps are lit, presses the pick completion button, and puts the picked products in a box corresponding to the recipient. This is a method in which the work is repeated for the number of products instructed.

In the method of the present invention, if the picking operation is correctly performed on the digital display after completion of the instructed pick, theoretical inventory = instructed inventory (or remaining instruction number) is displayed. If the operator can confirm that the ordered stock quantity (or the remaining quantity) and the actual stock quantity (or the actual quantity remaining) match after the picking operation, the matching confirmation notification function of the digital display Notify the higher system. The host system makes it judged that there was no erroneous pick in the picking work up to the point when the product was informed of the match confirmation, and the worker ordered and the actual inventory quantity (or the actual remaining quantity).
If the discrepancy is confirmed, the indicated number is corrected to the actual inventory number by the correction function of the digital display and the corrected number is notified to the host system. Upon receiving the notification of inconsistency, the host system notifies the worker to insert the forced inventory (or remaining number) check process into the work block in which the inconsistency occurs, and instructs the all digital display of the block to indicate the number of inventories (or Indicates the remaining number of instructions). The operator checks the indicated stock quantity (or the indicated remaining quantity) and the actual stock quantity (or the actual remaining quantity) of all the products in the block, and gives a matching confirmation notification for the matching products, but does not match. For products, the correction value is notified to the host system from the digital display by the method already described. When the forced inventory (or remaining number) check process work is completed, the worker restarts the normal picking work.

[0008] On the other hand, the higher-level system, during the previous forced inventory check work to the current forced inventory check work,
Based on the match confirmation information for each product notified from the digital display and the correction value information at the time of mismatch, from the final match confirmation information of the product to the compulsory inventory check, grasp the recipient who picked the product. The product name that may have made a picking error and the number of differences between the product name and the name of the recipient are printed out or displayed on the screen, and the operator is informed of which recipient the inspection should be performed on. Based on this information, the worker inspects only the relevant product in the relevant delivery destination box.

If the picking frequency is low, or
When the interval of the checking process becomes long, it is possible to narrow the inspection range by inserting a forcible checking process from the host system at regular intervals or at the time of replacement of workers.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of one embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an example of the picking process, showing the reason for inserting a forced inventory (or remaining number) check process and the principle of tracking picking mistakes. The vertical axis represents the processing result in units of recipients in order from the top, and the horizontal axis represents an example of a picked product. Explaining with the progress No. 1, the recipient 1 is instructed to pick two products A, the resulting theoretical inventory is 100, and the actual number is 100, and there is no difference in the inventory confirmation results, and a match confirmation notification is given. For product B,
It indicates that there was no picking instruction and no confirmation work was performed. The "-" symbol in the judgment / correction column in the figure indicates that the worker did not perform the confirmation work.

The first picking miss pattern is the progress N
This is the case when the picked product is not mistaken for the picked product that occurs at o2, but the picked number is wrong. In this example, the worker is picking from progress No. 2 to progress No. 4, but he has not checked the inventory and notices a mistake at the time of picking progress No. 5, so that the theoretical stock quantity should be corrected to the actual quantity. Shows that the theoretical inventory is incremented by 1 by the correction function of the digital display and the upper system is notified. As a result, the host system inserts the check process at the next progress No. 6, and the worker does not make a mistake with other products, and the product B,
Both C indicate that the coincidence confirmation notification is given. As a result, the higher-level system can recognize that a pick shortage error of one pick number has occurred only for the product A, and informs the worker that the check-required delivery destination No. is delivery destination 2 to delivery destination 5.
Therefore, if the worker inspects the box corresponding to the relevant addressee and corrects one shortage of the product A by inspecting the addressee 2,
The inspection work can be omitted for the later recipients.

The second picking miss pattern is the elapsed N
This is a case where the number of picks as generated at o9 is not wrong, but the merchandise to be picked is mistaken and the merchandise C to be picked is the adjacent merchandise A. In this example, the worker notices a mistake when picking the product A with the progress No. 13, and because the actual number of the product A is 5 short, the theoretical inventory is corrected by -5 and the discrepancy confirmation notification is sent to the upper system. It shows that it is doing. Therefore, as in the case of the first pattern, the check process work is inserted in the next progress No. 14, and as a result, there is no pick mistake in the product B, a coincidence confirmation notification, and a surplus of +5 in the product C are generated. It indicates that the higher system has been notified.
The upper-level system grasps that there are +5 pick misses in the product A and −5 pick misses in the product C,
Notify the worker that the check-required delivery destination numbers are the delivery destinations 6 to 11. In this case, the addressee 11 is an addressee that does not include the product in which the difference has occurred, and is excluded from the inspection target. If the worker sequentially inspects the boxes corresponding to the destination,
5 shortages of product C and 5 surpluses of product A were found in the destination 9 of the progress No9, and the number of differences coincided with the difference information output by the higher-level system, so it is not necessary to inspect the subsequent destinations. Become.

FIG. 2 shows a system of a relay picking configuration in which a plurality of flow racks are installed in multiple stages and connected between them by a conveyor, and four flow racks are arranged side by side.
Each flow rack is used as a work block unit. A worker to pick is placed in each block, and a transport conveyor with a stopper is installed on the front of the flow rack to stop the stacking box for each block. There is a box number indicator.

From the upstream, throwing in a collection box on which a label with a bar code corresponding to a destination is pasted, and the worker of each block reads the bar code stuck on the box stopped on the stopper of each block by BCR, The box number can be confirmed on the box number display, and at the same time, the digital display corresponding to the product to be picked in each block is turned on, and at the same time the number of instructions is displayed, and the worker picks as directed by the digital display. And put the picked products in the collection box,
Flow to the next block. By repeating the above work in each block, the picking work for one recipient is completed. This is a normal work flow for relay picking, but the work flow when one embodiment of the method of the present invention is added will be described below.

Until picking with the digital display, it is no different from the conventional work, but by installing the digital display as shown in FIG. 3, after pressing the pick completion button, the numerical display section is continuously instructed. Display the number of stocks (or the remaining number of instructions). The operator confirms the instructed stock quantity (or the remaining quantity of the instruction) and the actual quantity of the stock (or the actual remaining quantity), and if they are the same, presses the completion button again. It is judged that there was no mistake in the picking work up to this point. If there is a difference as a result of the check, the indicated inventory quantity (or the indicated remaining quantity) is changed to the actual inventory quantity (or the actual remaining quantity) with the "+" key or the "-" key attached to the digital display. After making corrections, by pressing the completion button again, the host system determines that some pick error (pick number error, product error, compound error, etc.) has occurred in the picking work up to this point, and the host system immediately A stock quantity (or remaining quantity) check process is inserted into the block where the pick mistake occurred.

Specifically, as shown in FIG. 4, a specific code such as "9999" is displayed on the display section of the box No. indicator of the corresponding block to indicate that the operator has inserted the check process. At the same time as the notification, the indicated stock quantity (or the indicated remaining quantity) is displayed on the numerical display part of the all-digital display of the concerned block, and the worker is shown the actual stock quantity (or the actual remaining quantity) of all the goods of the concerned block. Let the check work with.

The host system grasps the result, and FIG.
The picking mistake tracking list as shown in is output. This list makes it possible to efficiently find the stacking box that has caused the picking mistake.

As described above, as work after finding the box in which the picking mistake has occurred, the work of removing the insufficient product from the flow rack and the work of correcting it to the relevant box, and the work of removing the excess product from the box and returning it to the flow rack are performed. is there. This work also uses the picking mistake tracking list and, for example, goes to the picking block that contains the product that caused the picking mistake described in this list, and responds to the check number printed on this picking tracking list. When the read bar code is read by the BCR, as shown in FIG.
A specific code such as 8 "is displayed. By this, the operator is informed that the extraction / return process has been inserted, and at the same time, the indicated stock quantity (or the remaining instruction quantity) is displayed on the numeral display section of the corresponding digital display of the corresponding block. At that time, in case of pulling out, correct the extracted quantity with "-" key, and in case of returning, correct only return quantity with "+" key, and the post-processing of the picking error tracking result is completed. Will be done.

When the above-mentioned series of work is made into a work flow,
It becomes FIG. The check process insertion conditions at the time of a check request from the site in FIG. 7 and at the time of a regular check request from the system are devised to narrow the range to be checked, and the picking frequency and work characteristics can be appropriately changed. If they are inserted together, the responsibility range of the operator can be clarified, and at the same time, more efficient picking error tracking can be performed.

FIG. 8 shows an example of the configuration of a system for implementing the method of the present invention.

[0021]

As is apparent from the above description, according to the present invention, the inspection work is performed by the picking mistake tracking list only when the picking mistake occurs, and further, when the correction work for the number of differences is completed, Since it is not necessary to perform 100% inspection of the range, the number of inspection steps can be reduced.

Further, since the number of differences in picking mistakes can be provided as information, the accuracy of inspection can be improved and the inspection can be guaranteed by confirming the match between the number of detected mistakes and the number of differences.
