FIG. 10 is an explanatory diagram of a main part of a system of Examples 5 and 6.

  A lot of work places for the person in charge to inspect the goods are provided at the place where the goods are received and delivered. When the inspection process for warehousing is completed, each article is transported to a designated storage location and stored. In the inspection process, the identification data of the article to be inspected, the number of items and other items on the slip, the identification data of the worker, etc. are input to the management data. In the warehousing process and the leaving process, it is not always required to record the location where the inspection is performed in the management data, but in the present invention, in order to facilitate the search of the image data obtained by photographing the inspection work, The location code for specifying the work place and the work time are input to the management data.

  In the present invention, all inspection operations are photographed with a camera using moving images or the like. At this time, a location code for specifying the work place is added to the image data file obtained by photographing. The data specifying the work location may be data specifying the installation location of the camera. Further, the photographing time is added as attribute data to the photographed image data. Thereby, it is possible to search for all the operations at the time of entering and leaving the article using the photographing time and the location code, extract the photographed image data, and confirm the work contents. That is, this image data shows a state in which a predetermined work is being performed on the corresponding article at the location indicated by the location code at the shooting time.

  On the other hand, when an article is stored on a shelf provided as a storage location, conventionally, identification data for specifying the shelf is input to the management data. The identification data for specifying the shelves can be used as data for specifying the work place of the storage work as it is. However, when a shelf is photographed by a camera, images of a plurality of shelves and a plurality of articles may be photographed at the same time. Therefore, it is not possible to make a one-to-one correspondence between a location code for specifying a camera installation location and a shelf number.

  Therefore, for example, the above-described location code is added to an image data file obtained by photographing with a camera, while reference data indicating a correspondence relationship between a shelf number and a location code is created in advance. And when storing goods or picking, if you enter the shelf number using the management data input device, the reference data is automatically referred to, and the corresponding location code is entered into the management data To.

  For example, the management data and the image data file can be searched with a common location code by the above processing. For example, with respect to a certain article, management data relating to all work from entry to delivery and image data obtained by photographing the work can be extracted all at once using the location data as a key. Hereinafter, embodiments of the present invention will be described in detail for each example.

FIG. 1 is an explanatory diagram of the main part of the warehouse management system.
As shown in the figure, the warehouse 12 for storing articles is provided with areas such as an incoming baggage receiving place 14, a storage place 16, a packing work place 18, and a shipping processing place 20. When the article 26 is received, the inspection process is performed at the incoming goods receiving place 14 and stored on a predetermined shelf in the storage place 16. When a delivery instruction is issued, the corresponding article 26 is picked up from the storage place 16 and moved to the packing work place 18. An enlarged perspective view of a part of the packing work place 18 is shown in the lower circle in the figure. The article 26 is stored in the packing container 24 after the inspection process, and is shipped through the shipping processing place 20.

(Flow of goods)
The management data of the article 26 received in the warehouse 12 is updated every time an operation for changing the storage state is performed until the article 26 is delivered. The operation of changing the storage state is to move the goods received from the incoming goods receiving place 14 onto the shelf of the designated storage place 16 and store them, and then pick them up and carry them to the packing work place 18 for packing. It is an operation of moving the article 26 such as shipping through the processing place 20.

  The person in charge handles, for example, when goods 26 are stored in the warehouse 12, when stored on the shelves of the storage location 16, when picking, when packing into the packing container 24, when loading into a truck, etc. The management data 34 is updated using the barcode scanner 22 and the management data input device 23 such as a tablet computer. At this time, in addition to the quantity of the article and other information described in the instruction slip attached to the article 26, the identification code 36 of the person in charge, the identification code 38 of the article, and data for specifying the work place are included. include. The management data input device 23 inputs this management data 34 to the management server 54 through the network.

  In this embodiment, a label printed with a location code 30 for specifying a work place is attached to a work shelf 28 on which a packing container 24 is placed for packing work. The location code 30 is optically read by the bar code scanner 22 and acquired. Here, the location code 30 is data for specifying a work place. The person in charge acquires the identification code 36 of the person in charge from the name tag on the chest of his / her work clothes using the barcode scanner 22. The article identification code 38 is obtained by reading a barcode printed on the article 26 or its packaging using the barcode scanner 22.

  In the storage location 16, it is preferable that the shelf number 29 and the location code 30 for specifying the storage location when the article 26 is stored on the shelf are provided independently. In this example, the corresponding location code 30 is automatically acquired from the shelf number 29 and added to the management data 34. The location code 30 categorizes the warehouse 12 and specifies the work place. However, a large number of shelves for storing the articles 26 are arranged vertically and horizontally. Therefore, for example, a correspondence table may be created so that a plurality of shelf numbers 29 are associated with the same location code 30.

  The management server 54 adds the data acquired by the barcode scanner 22 to the management data 34 and stores it in the storage device. The storage device is built in the management server 54, for example. At this time, the management server 54 automatically generates the handling time 50 of the management data 34 and adds it as attribute data. The management data 34 includes an instruction slip number, a product name, a purchase source, a production number, a lot number, an expiration date, a shipping destination, etc., in correspondence with the identification code 38 for all articles 26 that are loaded and unloaded. Contains data. Therefore, when the article 26 moves in the warehouse 12, detailed data indicating when and where the article 26 is stored and how it is moved and shipped is accumulated in the management server 54.

  In this warehouse management system, all operations from the receipt of goods 26 to the warehouse 12 to the delivery are taken by the camera 39. Video shooting is preferred. Cameras 39 for continuously photographing the handling operation of the article 26 are installed at all work places where the storage state of the article 26 is changed. Data captured by these cameras 39 is an image data file 40. In this image data file 40, a location code 30 and a photographing time 42 indicating a photographing place by the camera 39 are added as attribute data.

  For example, a location code 30 that can distinguish each installation location is set for all installation locations of the camera 39. The location code 30 is data in which each area can be distinguished by dividing the interior of the warehouse 12 by areas of a size that can be captured by one camera 39.

  In the present invention, the management data and the captured image data are linked by collating the location code 30 that is the attribute data of the image data file 40 with the location code 30 included in the management data 34. Therefore, when the person in charge inputs the management data 34 using the management data input device 23, control is performed so that the location code 30 is always input. Further, when the camera 39 is installed, control is performed so that the location code 30 is always added to the image data file 40 photographed thereby.

FIG. 2 is an explanatory diagram showing an example of the location code setting screen 44.
The description of FIG. 1 will be continued with reference to FIG. The location code setting means 46 is activated by a computer program of the management server 54 (FIG. 1). The location code setting means 46 has a function of displaying the location code setting screen 44 on, for example, the management data input device 23 owned by the person in charge. The location code setting screen 44 includes a field for inputting an image data file name 45 taken by the camera 39 and a field for inputting the location code 30. These data are required to be input, and the image data file 40 can be stored in the storage device of the management server 54 by operating the OK button 48 after both are input.

  For example, the location code 30 may be automatically input by reading a label or an IC tag attached to the work shelf 28 (FIG. 1) or manually by a person in charge of installing the camera 39. Also good. Since the location code 30 is attribute data of the image data file 40 taken by the camera 39, it may be executed only once when the camera 39 is installed in a specific area in the warehouse. When the camera 39 is moved to another area, this process is executed again. For example, the image data file name 45 may be set in the location code 30. Alternatively, a correspondence table between the image data file name 45 and the location code 30 may be provided.

  On the other hand, when an image of a person in charge or an object working in the area is photographed by the camera 39, the image data generation means 47 automatically adds the acquired image data 43 and the photographing time 42 as attribute data. In the figure, the image data 43 is displayed as an image data group. This is composed of, for example, a moving image or a large number of still images obtained by shooting a single work. The photographing time 42 is a photographing start time, and the photographing time of each image data constituting the image data group can be obtained by conversion. In addition, data indicating the photographing time may be automatically added to every piece of image data using a built-in clock of the computer.

  It is preferable that the identification code 38 of the article, the identification code of the packaging container 24, the sign 32 shown in FIG. The sign 32 is data for specifying the packaging box 24, and the shipping destination is also specified thereby. These may be automatically recognized and coded by image processing and added as attribute data of the image. If the person's face can be recognized by the computer, the recognition result may be added as attribute data.

  One location code 30 is always set in an image data file 40 taken by a camera arranged at the same place. There may be an image data file 40 in which image data taken by moving the camera is mixed. In that case, an image data file 40 to which a new location code 30 is added is generated. If the camera 39 is not moved, one location code 30 is fixedly set for one camera.

  The cameras 39 are installed at all places where the article 26 is handled, and shoot all the handling operations of the goods. You may continue to drive during working hours. Further, it is preferable to operate so as to automatically start and start shooting when a moving body is detected in the shooting range, and to end shooting when returning to the original state. A still image may be taken every few seconds, or a moving image may be taken. Video is considered as a collection of still images.

FIG. 3 is an explanatory diagram of an inspection processing operation screen.
During the period from the arrival of the article 26 to the warehouse 12 to the delivery, the article 26 moves in the warehouse 12 and its storage state is changed. The inspection process is always performed before and after the process. For example, when an article 26 is unloaded from a truck at the time of arrival, an inspection is received. At this time, the article identification code 38 and the handling person identification code 36 are input. When the identification code 36 of the person in charge of handling is input, the person in charge name 49 is automatically displayed on the inspection processing operation screen 53 shown in FIG. The handling time 50 is automatically input by a built-in clock of the computer.

  At the time of warehousing work, the operator is requested to input the location code 30. As shown in FIG. 1, the person in charge reads the bar code or tag provided at the work place with the bar code scanner 22 and inputs the location code 30. The received goods 26 are transported to a designated shelf and stored. When the article 26 is stored on the shelf, the same inspection process as that at the time of arrival is performed. Thereafter, it is picked up and moved to the packing work place 18. When packing is completed, the product is loaded onto a truck or the like and shipped. Thus, the inspection process is performed every time the article 26 moves.

  In the example of FIG. 2, an example in which the shelf number 29 displayed for each shelf is input in order to register the storage location 16 of the article 26 in the management data 34 is shown. The camera 39 may be able to shoot with a plurality of shelves included in one screen. Accordingly, reference data 56 in which a plurality of shelf numbers are associated with one location code 30 is provided. That is, when the shelf number 29 is input to the inspection processing operation screen 53, the management data input device 23 automatically refers to the reference data 56 to acquire the location code 30 and displays it on the inspection processing operation screen 53. Thereafter, when the OK button 52 is operated, the management data 34 is input to the management server 54 (FIG. 1).

FIG. 4 is a block diagram showing an example of the system of the present invention.
The interrelationship of each data already described will be described using this figure. The management data 34 is stored and managed in the storage device of the management server 54. As already described, the management data 34 includes data such as an article identification code 38, shipping destination (or destination), date of manufacture, product name, expiration date, lot number, manufacturing number, purchase source, and the like. Whenever the storage state of the article 26 is changed in the warehouse 12, field input data 58 such as the identification code 36 of the person in charge of handling, the location code 30 of the movement source or movement destination, and the handling time 50 is added.

  The camera 39 is connected to the management server 54 via a network. Image data 43 taken by a large number of cameras 39 in the warehouse is transferred to the management server 54 and stored in the storage device. As shown in FIG. 4, when the site input data 58 is generated, the management data 34 is updated using the article identification code 38 as a key.

  During the input operation of the field input data 58, the handling time 50 is added as attribute data. When this work is taken by the camera 39 installed at the work place, the shooting time of any image data is taken. 42 coincides with the handling time 50. The location code 30 is also common. Thus, the field input data 58 and the image data file 40 are associated with each other. Thereby, in the management server 54, when it is desired to confirm the processing process of the specific article 26 by both the management data 34 and the image data file 40, the image data can be searched as follows.

FIG. 5 is an explanatory diagram of an image data search screen and its operation.
The image data search screen 62 is provided with a field for inputting an article identification code 38. When the identification code 38 is entered here, an article name 63 is automatically displayed. In the image data search screen 62, fields for inputting a search key such as a person in charge of handling, a shipping destination, a shipping date, a shipping quantity, a shelf life, a lot number, a manufacturing number, a purchase source, and the like are provided. When a search key in the key selection window 74 is selected, a check mark is entered in the check box 66 and the search execution button 68 is operated, the warehouse management data search means 70 is activated.

  In the example shown in the figure, extraction of the processing progress is requested for an article 26 whose article identification code 38 is “9501111” and whose shipping destination 76 and shipping date 78 are known. The management data 34 is searched, and several sets of the handling time 50 and location code 30 of the corresponding article are output. The image data search means 72 executes processing for reading out image data obtained by photographing these operations.

  The image data search means 72 selects image data whose handling time 50 and shooting time 42 match from the image data file 40 whose location code 30 matches. It does not have to be an exact match. Any image data obtained by photographing a series of operations may be extracted. Then, as shown in FIG. 5, for example, captured images at the time of arrival, storage in the storage place 16, picking, shipping, etc. are displayed all at once. An image in which the handling time 50 and the photographing time 42 are approximated is displayed, and by operating the shift button 82, it is possible to view the images before and after that. A video may be displayed.

  The above processing can be executed by operating, for example, the management data input device 23 connected to the management server 54 or the management server 54. The processing is started by starting the warehouse management data search means 70 and the image data search means 72 in the management server 54. By designating a search key on the image data search screen 62 displayed on the management data input device 23, it is possible to instantaneously display the corresponding processing history and an image of the work in a batch.

  As described above, according to the system of the present invention, for example, a specific product, a specific shipping destination, a specific lot number (manufacturing date, etc.) with a specific best-before date, and the like are specified. Search for image data at once. In particular, even when products with the same product identification code and the same expiration date are scattered on shelves in different storage locations, the reference data 56 and the image data file 40 have the common location code 30, so It is possible to perform a confirmation process by extracting the processing process of the article corresponding to the above and all images taken of the process at once.

  In the system of the present invention described above, by using the location code 30, it is possible to link the management data of all the articles 26 and the image data taken at the place where the articles 26 are handled. When this is used, for example, even when there are a large number of articles 26 having the same identification code, first, by analyzing the management data, how many articles 26 are stored on which shelves, and when and how You can find out where it was shipped in the process or whether it is still stored on the shelf.

  For example, it is assumed that a customer contacts the customer later that an incorrect product is included in the products packed for shipping. However, even if the result data is searched, it is shipped correctly, so it is not a shortage, and you may have arranged the wrong product and sent it. Conventionally, in this case, there is no choice but to trust the customer's story. However, with this system, it is possible to quickly create an accurate survey report to the customer.

  That is, it is possible to check when an article shipped to a destination on a certain shipping date 78 is received and stored on which shelf. Next, the handling time and the location code are extracted from the management data updated until the corresponding article 26 is shipped, and the image data file is searched using this as a key. In this way, all images taken while the corresponding article 26 or group of articles 26 is moving in the warehouse 12 are output all at once. For example, if all necessary articles 26 are definitely packed and shipped, a copy of those images can be presented to the delivery destination for explanation.

  For example, when an article identification code 38 is correctly input at the time of packing but is not actually packed, a photographed image is extracted using the article identification code 38 and the shipping date 78 as keys. can do. In other words, the management data of the article 26 includes a plurality of location codes 30 indicating the movement history of the article 26 in the warehouse 12. The corresponding image data is extracted using the location code 30 and the handling time as keys. For example, it is possible to find a case where a person in charge finds that a part of an article 26 to be packed is damaged and the article 26 is extracted and packed and shipped without being refilled. .

Furthermore, according to the system of the present invention, by searching and extracting images taken by the camera 39, confirmation of the flow of a specific product, the state of the product, the person in charge who actually handled the product and the work method It is possible to easily check the stored shelves at any time.

  The location code setting unit 46, the image data generation unit 47, the warehouse management data search unit 70, and the image data search unit 72 are realized by a computer program of the management server 54. It may be incorporated. Further, the management data input device 23 may simply function as a terminal device of the management server 54, and all the actual processing may be executed by the management server 54.

FIG. 6 is a block diagram illustrating the warehouse management system according to the second embodiment.
As shown in the above embodiment, by searching the image data 43, it is possible to easily check the flow of a specific product, the state of the product, the person in charge who actually handled the product, and the work method at any time. it can. For example, the screen extracted as a result of the search is captured and transmitted to the parties concerned along with the report. In the report, the identification code 36 of the person in charge, the identification code 38 of the article, the location code 30, the handling time 50, etc. are described, and a captured screen is attached.

  However, when an operation to change the storage state of the article is performed, in order to confirm whether the operation is being performed reliably in a step-by-step manner, the screen before and after the corresponding image data is displayed as a movie, It is preferable to examine the work contents in detail.

  On the other hand, as described in Japanese Patent No. 5719137 (Patent Document 2), cases in which a speech recognition picking system is employed for warehouse management are increasing. In the voice recognition picking system, as shown in FIG. 6, a person in charge 84 wears a terminal device 86 equipped with a microphone and an earphone, and advances the picking work while interacting with the automatic voice response means 88 of the computer.

  The communication device 86 receives the instruction information transmitted from the automatic voice response means 88 by voice. The person in charge 84 works according to the instruction. When the person in charge 84 takes out the article, it scans with the scanner, and the data is returned to the automatic voice response means 88 through the communication device 86.

  In such a work, the automatic voice response means 88 gives a detailed instruction to the person in charge 84, exchanges the voice, and proceeds with the confirmation. The automatic voice response means 88 includes voice recognition means 90 that receives a response by the voice of the person in charge 84 and converts it into a character code for processing. You can prevent mistakes by proceeding while confirming the work one voice at a time. The person in charge 84 has both hands free and can work efficiently.

  When such a system is adopted, it is possible to specifically analyze the progress of the work in detail by examining the response contents of the person in charge 84 who is working and the automatic voice response means 88. Therefore, in this embodiment, the automatic voice response means 88 generates a response record data file 92 with all the voice responses transmitted and received as character codes.

  Extraction response data 94 in a necessary range is extracted from the response record data file 92, and control is performed so that composite image data 91 combined with the photographed image is displayed and output as shown in FIG. In the response record data file 92 of the extracted response data 94, as shown in FIG. 6, the voice “Q” output from the automatic voice response means 88, the voice “A” uttered by the person in charge 84, the scanner and the like Device operation records are included (“A” not including audio). In addition, accurate processing time data is included.

  The captured image extracted by the image data search means 72 described in the first embodiment can also be searched at the handling time 50. The format of both time data is made to correspond. When the image data search means 72 searches the image data file 40 and extracts the corresponding photographed image, the response record data file 92 is searched with reference to the handling time 50.

  Then, for example, the extraction response data 94 for 5 minutes before and after the handling time 50 is taken out. Alternatively, the extraction response data 94 for, for example, 20 lines before and after the handling time 50 is taken out. That is, a certain time range or a certain amount of data is set, and the corresponding extraction response data 94 is extracted from the response record data file 92. Then, the image synthesizing unit 96 synthesizes the extracted extraction response data 94 with the captured image to generate synthesized image data 91.

  Thus, as shown in FIG. 6, the composite image data 91 including the extraction response data 94 is displayed on the computer display. When this screen is captured to create a report, the specific work performed before and after the shooting time of the image can be confirmed with the characters included in the extraction response data 94.

  If the above process is executed within a certain time range, a moving image that continuously displays the composite image data 91 within the time range can be generated. Thereby, it is possible to reproduce a moving image with so-called captions in an arbitrary range by synchronizing the sound, the character, and the moving image. In particular, when the voice is difficult to hear, the characters displayed on the screen function effectively. In addition, it is possible to accurately analyze the work content with characters even for a moving image in which no sound is recorded.

FIG. 7 is a system block diagram of the third embodiment.
In the figure, a photographic image display window 102 and a response display window 104 are displayed on the display 100. Here, in the above system, a captured image display control unit 106, a response display control unit 108, and a synchronization control unit 110 are newly provided. In order to control these on the display screen, a captured image control button 112, a response display control button 114, a synchronization control button 116, and a capture button 118 are provided.

  The captured image display control means 106 reads out the captured image from the image data file 40 and executes control to display it on the captured image display window 102. The response display control means 108 executes control for reading character data from the response record data file 92 and displaying it on the response display window 104.

  When the captured image is displayed in the captured image display window 102, the synchronization control unit 110 controls to extract the corresponding response data 94 and display it in the response display window 104. Specifically, a signal for identifying the captured image is transmitted from the synchronization control unit 110 to the response display control unit 108. The response display control means 108 searches the response record data file 92, reads out the corresponding character data, and displays it.

  The captured image control button 112 and the response display control button 114 include, for example, a forward button and a backward button for manually scrolling the display of the data file. These are indicated by arrows in the figure. The synchronization control button 116 includes a play button and a stop button.

  The above system operates as follows. First, when the forward or backward button of the photographed image control button 112 is operated, the photographed image display control means 106 reads a desired photographed image from the image data file 40 and displays it on the photographed image display window 102. Next, when the playback button of the synchronization control button 116 is operated, moving image display is started from the captured image displayed in the captured image display window 102. The response display control means 108 retrieves and reads the response data 94 to be synchronized with the displayed captured image, and displays it in association with the response display window 104. With the above operation, moving image display is started from a desired photographed image, and characters indicating response contents are displayed in synchronization.

  When the stop button of the synchronization control button 116 is operated, the reproduction of the moving image is stopped. Here, when the response display control button 114 is operated, the response record data displayed in the response display window 104 can be scrolled while the image display of the captured image display window 102 is fixed. Therefore, it is possible to confirm the response contents before and after the specific photographed image with characters. While the display of the response record data 94 is fixed, the photographed image control button 112 can be operated to scroll only the photographed image independently. In this way, if the screen displaying the optimal information for analysis is displayed on the display and the capture button 118 is operated, the screen can be stored in the storage device of the management server 54 (FIG. 1) and output at any time. become.

  It should be noted that the above-described response record data file 92 includes an example in which the voice “Q” output from the automatic voice response means 88, the voice “A” uttered by the person in charge 84, and the operation record of the scanner and other devices are included. did. However, there are systems in which the contents of work instructions are displayed on the display with characters or the like, and a “YES” button and a “NO” button are provided for response to operate them. In either case, the response record data file 92 may be generated and displayed on the display as character information from which the work content can be read.

  According to the above embodiment, the image data file 40 is searched by using the identification code 38 of the goods to be packed, the delivery destination name, the handling time 50, etc. as keys, and the screen and the content of the work can be easily taken. It became possible to confirm. Therefore, in response to an inquiry from the shipping destination, the person in charge can extract various data including the corresponding screen from the database and report it to the shipping destination.

  Therefore, at the same time as shipping, it is conceivable to notify the shipping destination of the access method and search key of the image data file 40 of the management server 54 and to permit viewing of the image data file 40. By doing so, the shipping destination can freely search the image data file 40 at any time and check the handling progress of the delivered article. However, when the customer accesses the image data file 40, there arises a problem that it becomes possible to know the shipping data of the third party. That is, there is a problem of confidentiality of customer information.

  It is conceivable to provide a customer dedicated site in the management server 54 and store image data for showing the handling progress of the package delivered to the customer. However, individually storing image data obtained by picking, shipping work, etc. for all of a large number of shipments on a server is unrealistic because the storage area becomes enormous. In the fourth embodiment, this is solved.

FIG. 8 shows an operation flow of the system of the fourth embodiment.
The delivery form 120 shown in this figure is bundled with the package to be shipped. An invoice with the same contents may be digitized and sent to a shipping destination by e-mail. In this embodiment, since the delivery note 120 is printed and bundled in the package, the delivery note can be used immediately at the time of inspection work. An inquiry code 128 is displayed on this delivery note 120 so that an image of the packing operation in the warehouse can be seen at any time.

  In addition, a package is a thing packed in a box or a bag and delivered to a shipping destination. This package contains various articles to be delivered. At the shipping destination, the contents of the package are accepted, and if a missing item or an error is found, the inquiry code 128 can be used to find the cause.

  In order to realize this system, in this embodiment, in the management server 54 (FIG. 1), the search expression generation unit 132, the encoding unit 134, the delivery form generation unit 129, and the authentication processing unit 138 for each package are provided. And a decryption unit 142 and a URL notification unit 148 are newly provided. The image data search means 72 uses the one already described in the embodiment.

  When packing is completed, for example, as illustrated in FIG. 8, the encoding unit 134 reads items necessary for generating the inquiry code from the management data 34 and generates the inquiry code 128. The inquiry code 128 is obtained by, for example, directly encoding a search expression for extracting an image obtained by photographing the packing operation in the warehouse of the packing body from the image data file 40. Note that the inquiry code 128 may be any symbol that can identify the package and identify the corresponding search expression by any means. The search expression may be such that search keys that can operate the image data search means 72 are arranged.

  The inquiry code 128 in this embodiment is obtained by converting the member number 131 and the search expression 130 into numbers by an arithmetic process such as compression encryption. It may be a simple list of numbers or alphanumeric characters. In addition, it is preferable to print the two-dimensional code 126 which can read the inquiry code 128 with a mobile phone on the delivery note 120.

  Since the person in charge at the shipping destination cannot access the data file in the management server, it cannot be used even if the retrieval formula is known. Therefore, the query code 128 may be a search expression as it is. However, the search expression generally has a complicated structure. Therefore, the encoding unit 134 is used to generate a query code 128 having a simple structure and notify the shipping destination.

  The person in charge at the shipping destination opens the package and performs an inspection process while looking at the delivery note. It is sufficient that all items have been delivered, but for example, if there is a shortage, etc., a mobile phone or a smart phone is used to log in to the site operated by the shipping source. When the two-dimensional code 126 of the delivery note shown in FIG. 8 is read by a smart phone and a transmission operation is performed, the authentication processing means 138 of the management server 54 (FIG. 1) automatically performs an authentication process from the telephone number and performs an inquiry code 128. To get.

  When the inquiry code 128 is acquired, the decryption means 142 refers to the management data 34 and restores the member number 131 and the search formula 130. If the inquiry code 128 is simply a code for identifying the package, the decryption means 142 generates a corresponding search expression using the management data 34 and passes it to the image data search means 72. Good.

  The image data search means 72 of the management server searches the image data file 40 and the response record data file 92 using this search formula 130. Thus, the extracted image data 144 and the extracted response data 94 are obtained. These data are uploaded to the download site 146 of the management server 54 (FIG. 1). Since the corresponding data is extracted only for a specific package, the amount of data is not large. Accordingly, the storage capacity of the download site 146 can be reduced.

  The URL notification means 148 refers to the member number 131 included in the inquiry code 128 and extracts the registered mail address of the customer from the management data 34. Then, after the search process is completed, a download URL is transmitted to the registered mail address. Since all the above processes are automatically executed, the person in charge at the shipping destination can always check the state of the packing operation in the warehouse of the package.

  The extracted image data 144 and the extracted response data 94 uploaded to a dedicated download site can be displayed on a screen as shown on the display 100 in FIG. 7, for example. Therefore, all the packing processes can be confirmed in detail by scrolling. These extracted data may be viewed on a download site, or downloaded to a personal computer or the like as a shipping destination.

  There are only a few cases where it is necessary to check the handling progress of the package due to the occurrence of trouble at a distribution center or the like that carries out a lot of packing work and shipping work every day. However, it is costly to arrange a dedicated person in charge for the response. As in this embodiment, the system in which the person in charge at the shipping destination can automatically view the handling progress of the parts received at any time has the effect of obtaining the convenience and trust of the customer.

  According to the above embodiment, it is possible to check the flow of packed articles without omission using the image data file. However, it is necessary to store a large amount of image data files. In this embodiment, the search and reference of the data file are facilitated by the following processing.

FIG. 9 is an explanatory diagram of a main part of the systems of the fifth and sixth embodiments.
In the above embodiment, the bar code scanner 22 is used to read other information such as the quantity of articles on the instruction slip. In this embodiment, for example, the instruction slip 150 placed on the packaging container 24 is photographed by the camera 39 and the slip number, customer name, and shipping destination store name on the slip are captured by the character recognition means (OCR) 152. Etc. Thereby, the management data input device 23 can acquire the data on the instruction slip 150 in a short time. Further, the time when the instruction slip 150 is photographed by the camera 39 or the time obtained by character recognition of the data on the instruction slip 150 is included in the management data 154 for each instruction slip as a work start time and stored in the storage device.

  On the other hand, the instruction slip is taken again at the end of the work. Alternatively, the slip number of the instruction slip 150 may be read using the barcode scanner 22. The time at which this processing is performed is included in the management data as work end time and stored in the storage device. Further, a stop button or stop bar code 156 for notifying the end of work may be provided in the packing box 24 or the work place 28 and read by the bar code scanner 22. The work may be continuously photographed and an image data file of a necessary part may be created at an appropriate timing. Alternatively, the photographing apparatus may be activated at the start of work and the camera 39 may be stopped at the end of the work.

  The image data file 158 obtained by photographing the work situation is stored in the storage device for each instruction slip 150 as a unit from the work start time to the work end time. When the search device searches using the slip number, customer name, or store name as a key, the image data file 158 obtained by photographing the work and the management data 154 for each designated slip are extracted and displayed. The corresponding one unit of the image data file 158 can freely scroll back and forth in the range from the work start time to the work end time. Since only necessary photographing results are stored, the storage area can be saved and the search process can be speeded up.

  At the same time as the above work, the product code and the individual identification number (serial number, lot number, expiration date, etc.) of the goods to be packed are read by the barcode scanner 22 or the camera 39 and added to the management data 154 for each instruction slip. Good. As a result, even if the product has the same product code, it is possible to identify each item individually and check when and in what form the image data file 158 has been shipped. Is possible.

Example 6 will be described with reference to FIG.
A speaker 160 and a display 162 are arranged next to the camera that takes the packaging work. In the instruction slip management data 154 for managing the delivery work, a code for specifying a shipping destination store name, an individual identification code of an article to be delivered, and a product code are stored. Based on these pieces of information, the worker stores the goods in the packing container 24 and ships them.

  Here, there is a case where the customer is required to enclose an article accessory, reference material, or sample in the packing container 24 for packing the article. This is an operation that is added as an option to the normal packing operation for a specific customer.

  Normally, the contents of such optional work are described in the instruction slip 150. The worker works while confirming the instruction slip 150. However, this work can lead to misreading and misunderstandings.

  Therefore, it is read by the camera 39 and stored as the attached message 166 in the management data 154 for each instruction slip. It may be image data or character data. When the customer code and the product code are input to the computer during the packing operation, the computer reads the attached message 166 from the management data 154 for each instruction slip, synthesizes it, and outputs it from the speaker 160. . At the same time, the attached message 166 is displayed on the display 162.

  The image data file 158 obtained by photographing the packing work or the instruction slip 150 is displayed on the display 162 each time. The attached message 166 may be displayed and controlled side by side with these image data files 158. As a result, the operator can reliably execute the specific optional work required for each packing work without error.
