  Then, based on the content displayed on the display unit 23h of the RF handy writer 23, the operation of reading the barcode 12 attached to each member 11 with the RF handy writer 23 is performed again. At this time, when the ID generation unit 23c confirms that the product name of the member 11 is a from the code number of the member 11 from which the barcode 12 is read, the product name a and the quantity 1 are stored in the memory 23f. Let Subsequently, the product name and quantity of the member 11 to be loaded on the physical distribution carriage 21 stored in the memory 23f and the product name and quantity of the member 11 confirmed by the ID generation unit 23c are read to the loading member confirmation unit 23g. An operation of comparing these is performed in the loading member confirmation unit 23g.

  Here, when the ID generation unit 23c confirms that the product name of the member 11 from which the barcode 12 has been read is a, the count value that is counted by one member 11 of the product name a and stored in the memory 23f. Becomes three. On the other hand, the memory 23f stores two members 11 of the product name a as the members 11 to be loaded on the first logistics cart 21. For this reason, according to these comparison results, “loading prohibited” or “error” is displayed on the display unit 23h. At this time, assuming that the member 11 whose product name is newly confirmed by the ID generation unit 23c is not counted, the count value stored in the memory 23f is two from the three count values before the count. Returned to

  In this way, the work of comparing the product name and quantity of the member 11 to be loaded on the physical distribution carriage 21 stored in the memory 23f with the product name and quantity of the member 11 confirmed by the ID generation unit 23c is a loading member confirmation unit 23g. Done in When the loading member confirmation unit 23g confirms that all the barcodes 12 of the members 11 to be loaded on the logistics cart 21 have been read by the RF handy writer 23, the display unit 23h displays “Reading Complete” and “No. 1”. "Please communicate with the IC tag 22 attached to the logistics cart 21".

  Then, based on the content displayed on the display unit 23h of the RF handy writer 23, wireless communication is performed between the wireless communication unit 23d of the RF handy writer 23 and the IC tag 22 attached to the logistics cart 21, The IC tag authenticating unit 23e of the RF handy writer 23 performs authentication using an ID input to the IC tag 22 in advance. At this time, the ID previously input to the IC tag 22 is transmitted from the IC tag 22 to the IC tag authenticating unit 23e via the wireless communication unit 23d of the RF handy writer 23, and the distribution cart 21 stored in the memory 23f is transmitted. The number is sent to the IC tag authentication unit 23e.

  Thereafter, in the IC tag authenticating unit 23e, there is an operation of confirming whether or not the number of the logistics cart 21 included in the ID input in advance to the IC tag 22 matches the number of the logistics cart 21 stored in the memory 23f. Done. If it is confirmed by the confirmation work that the IC tag authenticating unit 23e matches, an ID including the product name ID and serial number of each member 11 stored in the memory 23f is transmitted via the ID generating unit 23c. The data is sent to the wireless communication unit 23d and written to the IC tag 22 attached to the logistics cart 21 through the wireless communication unit 23d.

  Here, as described above, the IC tag 22 attached to the logistics cart 21 is previously input with an ID consisting of the number of the logistics cart 21 and the name of the logistics center 20. Therefore, as shown in FIG. 9, the ID of each member 11, the number of the distribution vehicle 21, and the name of the distribution center 20 are stored in the IC tag 22 attached to the distribution vehicle 21. In FIG. 9, as the information written in the IC tag 22 attached to the logistics cart 21, the product names of the members 11 named α0001, α0002, β0001, γ0001, γ0002 are added to the first logistics cart 21 in the logistics center A. It shows that six members 11 each having an ID consisting of an ID and a serial number are loaded. As described above, in the product name ID, α is the product name ID of the member 11 whose product name is a, and β is the product name ID of the member 11 whose product name is b. γ is the product name ID of the member 11 whose product name is c.

  When the IC tag authenticating unit 23e confirms that the number of the logistics truck 21 included in the ID input in advance to the IC tag 22 matches the number of the logistics truck 21 stored in the memory 23f, the memory 23f The ID of each member 11 and the number of the logistics cart 21 stored and stored in the server are transmitted to the server 27 via the ID generation unit 23c. When the server 27 confirms that all the members 11 are loaded on the distribution cart 21 from the received ID of each member 11 and the number of the distribution cart 21, as shown in FIG. The database 28 of 20 stores the product name and serial number of each member 11, the number of the distribution cart 21, and the name of the distribution center 20. At this time, the server 27 sends a command to delete the number of the distribution cart 21, the ID of each member 11 and the product name and quantity of the member 11 to be loaded on the distribution cart 21 stored in the memory 23 f. The information written in the memory 23f is deleted.

  Thereafter, when the logistics cart 21 loaded with the plurality of members 11 passes through the shipping gate 25, the IC tag reader 24 attached to the shipping gate 25 reads the IC tag 22 attached to the logistics cart 21. Is called. Then, as shown in FIG. 4, the information written in the IC tag 22 (see FIG. 9) is sent to the server 27 via the LAN 26, and the information stored in the database 28 of each distribution center 20 is updated. . That is, as shown in FIG. 10, the database 28 of each distribution center 20 stores whether the distribution cart 21 and the members 11 loaded on the distribution cart 21 are shipped or in stock. For example, when the first logistics cart 21 passes the shipping gate 25 of the logistics center A, the information written in the IC tag 22 attached to the logistics cart 21 is sent to the server 27 via the LAN 26, and the logistics The database 28 of the center A is rewritten to the contents that the distribution cart 21 and the member 11 loaded on the distribution cart 21 are shipped from the stock.

  In this way, by reading the IC tag 22 attached to the logistics cart 21 with the IC tag reader 24 attached to the shipping gate 25, the number of the logistics cart 21 shipped from each logistics center 20 and this logistics The server 27 can manage the product name and quantity of the member 11 loaded on the carriage 21.

  Further, the information stored in the database 28 of each distribution center 20 is output to a terminal device (not shown) such as a personal computer connected to the server 27 as a table as shown in FIG. It can be managed well. That is, by operating this terminal device and rearranging the table as shown in FIG. 10 for each logistics cart 21, for example, it can be immediately known that the first logistics cart 21 has been shipped.

  In addition, the structure of the said distribution center 20 is a structure common in each following embodiment. Therefore, in each of the following embodiments, the description will focus on the configuration of the finished product center 30 to which the distribution cart 21 shipped from the distribution center 20 is delivered.

Embodiment 1 of the Invention
In the logistics management system of this embodiment, as shown in FIGS. 3 and 11, the finished product center 30 is an IC as a second terminal device that reads the IC tag 22 of the logistics cart 21 delivered from each logistics center 20. A pole 32 on which a tag reader 31 is installed, a sorting cart 33 that sorts the members 11 by customer 40 by extracting the members 11 required to assemble the finished product from the logistics cart 21 that has passed through the pole 32; A LAN 34 connected to the IC tag reader 31 and the sorting cart 33 installed in 32, and a server 35 as a second management server for managing inventory of the members 11 and the distribution cart 21 by being connected to the LAN 34. It has.

  The sorting cart 33 is provided with a barcode reader 36, a reader / writer 37, and a monitor 38 as shown in FIG. 12, and among these, the reader / writer 37 is a finished product via a LAN 34 from a LAN interface 37f. It is connected to the server 35 of the center 30.

  In the finished product center 30, when the member 11 is transshipped from the distribution cart 21 to the sorting cart 33, an operation of reading the barcode 12 attached to the member 11 by the barcode reader 36 installed in the sorting cart 33 is performed. Is called. For this reason, as shown in FIG. 12, the barcode reader 36 is read by the scanner unit 36a that reads the barcode 12 by irradiating the barcode 12 attached to each member 11 with a laser beam, and the scanner unit 36a. And a barcode analysis unit 36b for analyzing the barcode 12.

  Further, the reader / writer 37 installed on the sorting cart 33 together with the barcode reader 36 is manufactured from the code number of each member 11 obtained by the analysis of the barcode analysis unit 36b in the barcode reader 36, as shown in FIG. An ID generation unit 37a that confirms the name and generates an ID (product name ID) based on the product name, a wireless communication unit 37b that performs wireless communication with the IC tag 22 attached to the logistics cart 21, and the IC tag 22 The IC tag authenticating unit 37c for authenticating the IC tag 22 by wireless communication and the product name ID of each member 11 generated by the ID generating unit 37a are inputted and the member 11 loaded on the sorting cart 33 is confirmed. The loading member confirmation part 37d to be performed, the product name and quantity of the member 11 to be loaded on the sorting cart 33, and the loading on the sorting cart 33 A LAN 37 is connected to the memory 37e for storing the product name and quantity of the inserted member 11 and the IC tag authenticating unit 37c and the loading member confirming unit 37d and exchanges information with the server 35 via the LAN 34. And an interface 37f.

  Here, as described above, based on the order information of the product transmitted from the customer 40 to the finished product center 30 through the Internet or the like, the member 11 and the quantity necessary for assembling the finished product in the server 35 are the customer 40. Every one is required. The database 39 of the finished product center 30 stores the number of the sorting cart 33, 40 customers, and the product name and quantity of the member 11 to be loaded on the sorting cart 33. That is, in the database 39 of the finished product center 30, as shown in FIG. 13, for example, the 11th sorting cart 33 is provided for the P residence, and the product name is used as the member 11 loaded on the 11th sorting cart 33. It is stored that there are two members 11 of a, two members 11 of product name b, and one member 11 of product name c. On the other hand, the reader / writer 37 installed in each sorting cart 33 is previously input with the number of the sorting cart 33 in its memory 37e.

  When starting the loading of the member 11 onto the sorting cart 33, a sorting button stored in the memory 37e is stored by pressing a start button (not shown) installed on the reader / writer 37 as shown in FIG. The number of the carriage 33 is transmitted to the loading member confirmation unit 37d, and is transmitted from the LAN 34 interface to the server 35 via the LAN 34. When the server 35 confirms the number of the sorting cart 33, information on the customer names 40 stored in the database 39 of the finished product center 30 and the product names and quantities of the members 11 to be loaded on the sorting cart 33 (see FIG. 13) is transmitted from the LAN interface 37f to the loading member confirmation unit 37d via the LAN 34 and stored in the memory 37e.

  Further, in the finished product center 30, the distribution center 20 is connected to a terminal device (not shown) such as a personal computer connected to the server 35 in order to request delivery of the members 11 necessary for assembling the finished product to each logistics center 20. And the product name and quantity of the member 11 requested to be delivered to the distribution center 20 are input. 14A, the database 39 of the finished product center 30 stores the name of the distribution center 20, the product name and quantity of the member 11 requested to be delivered to the distribution center 20, and each distribution center. The quantity of the members 11 existing as stock by being delivered from 20 to the finished product center 30 and the quantity of the members 11 not yet delivered to the finished product center 30 are stored. That is, in the table shown in FIG. 14 (A), the quantity of the members 11 that are in stock as a result of being delivered from each distribution center 20 to the finished product center 30 and the quantity still being delivered from each distribution center 20 to the finished product center 30. The sum of the quantity of the non-members 11 is equal to the quantity of the parts 11 requested to be delivered to each distribution center 20.

  Then, for example, as shown in FIG. 14A, from the finished product center 30 to the distribution center A, five members 11 of the product name a, three members 11 of the product name b, and members 11 of the product name c Suppose you request 3 each. At this time, the IC tag 22 attached to the logistics cart 21 shipped from the logistics center A is not yet delivered from the logistics center A to the finished product center 30, that is, the IC tag installed on the pole 32. In a state where it is not read by the leader 31, five members 11 of the product name a, three members 11 of the product name b, and three members 11 of the product name c are not yet delivered from the distribution center A to the finished product center 30. Is stored in the database 39 of the finished product center 30, and the number of stocks of the members 11 of the product names a, b, and c in the finished product center 30 is zero.

  In the finished product center 30 configured in this way, as shown in FIG. 3, the distribution cart 21 shipped from each distribution center 20 is received. When the logistics cart 21 passes through the pole 32, the IC tag 22 attached to the logistics cart 21 is read into the IC tag reader 31 installed on the pole 32. At this time, wireless communication is performed between the IC tag reader 31 and the IC tag 22 attached to the logistics cart 21, so that the IC tag reader 31 performs authentication using the ID previously input to the IC tag 22. Is called.

  Specifically, first, when wireless communication is started between the IC tag reader 31 and the IC tag 22 attached to the logistics cart 21, the IC tag reader 31 generates a random number and encrypts the random number. And transmitted to the IC tag 22. The cipher transmitted to the IC tag 22 attached to the distribution cart 21 is decrypted by the IC tag 22, and the random number before being encrypted is confirmed. Then, the random number confirmed by the IC tag 22 is transmitted to the IC tag reader 31. Thereafter, the IC tag reader 31 checks whether or not the random number generated for transmission to the IC tag 22 matches the random number transmitted from the IC tag 22.

  When the IC tag reader 31 confirms that these random numbers match, the IC tag reader 31 then requests the information written in the IC tag 22 from the IC tag 22 attached to the logistics cart 21. Signal is transmitted. Then, in response to a request from the IC tag reader 31, the information written in the IC tag 22 is transmitted from the IC tag 22 attached to the logistics cart 21 to the IC tag reader 31, and the information written in the IC tag 22 is further transmitted. Is transmitted to the server 35 via the LAN 34 (see FIG. 11). On the other hand, as shown above, the information shown in FIG. 10 is stored in the database 28 of each distribution center 20.

  The server 35 refers to the information stored in the database 28 of each distribution center 20 so that the information stored in the database 28 of each distribution center 20 matches the information written in the IC tag 22. If it is confirmed, the reading operation of the IC tag 22 by the IC tag reader 31 is normally completed. At this time, the rotating lamp 60 installed at the upper end of the pole 32 rotates while lighting for a predetermined time. Further, by referring to the information stored in the database 28 of each distribution center 20, information that matches the information written in the IC tag 22 among the information stored in the database 28 of each distribution center 20 is a finished product. It is stored in the database 39 of the center 30. That is, in the database 39 of the finished product center 30, as shown in FIG. 15, the number of the logistics cart 21 delivered to the finished product center 30, the name of the logistics center 20 to which the logistics cart 21 belongs, and the logistics The product name and serial number of the member 11 loaded on the carriage 21 and the loading state of each member 11 on the sorting carriage 33 are stored in association with each other.

  On the other hand, when the server 35 confirms that the information stored in the database 28 of each distribution center 20 and the information written in the IC tag 22 do not match, the IC tag reader 31 reads the IC tag 22. Since it does not end normally, the revolving lamp 60 installed at the upper end of the pole 32 rotates while being lit for a predetermined time in a color different from that when the reading operation of the IC tag 22 by the IC tag reader 31 is normally completed.

  Specifically, when the IC tag 22 attached to the distribution cart 21 is read by the IC tag reader 31, the information written in the IC tag 22 shown in FIG. 14B is transmitted to the server 35 via the LAN 34. Then, the information written in the IC tag 22 is confirmed in the server 35. That is, in the server 35, it is confirmed that the logistics cart 21 delivered to the finished product center 30 is the first logistics cart 21 shipped from the logistics center A, and each member 11 written in the IC tag 22 is confirmed. The product name and quantity are confirmed from the ID.

  The server 35 refers to the information stored in the database 28 of the distribution center A shown in FIG. 10 so that the information stored in the database 28 of the distribution center A and the information written in the IC tag 22 are changed. When it is confirmed that the information matches, the information that matches the information written in the IC tag 22 among the information stored in the database 28 of the distribution center A is stored in the database 39 of the finished product center 30 as shown in FIG. Remembered. That is, in the database 39 of the finished product center 30, the number of the logistics cart 21 is No. 1, the logistics cart 21 belongs to the logistics center A, and the six members loaded on the logistics cart 21. 11 product names and serial numbers and the fact that the loading of these six members 11 into the sorting cart 33 is incomplete is stored in association with each other. Note that the information written in the IC tag 22 shown in FIG. 14B is the same as the information written in the IC tag 22 shown in FIG.

  At this time, the server 35 confirms the product name and quantity from the ID of each member 11 written in the IC tag 22 attached to the logistics cart 21, so that the member of the product name a is stored in the logistics cart 21. It is required that two members 11, one member 11 with a product name b, and two members 11 with a product name c are loaded.

  Then, the information shown in FIG. 14A stored in the database 39 of the finished product center 30 is read by the server 35, and the database of the finished product center 30 is based on the information written in the IC tag 22 in the server 35. The information shown in FIG. 14A stored in 39 is rewritten. That is, in the table shown in FIG. 14A, the quantity of the members 11 that are in stock as a result of being delivered from each logistics center 20 to the finished product center 30 and the delivery from each logistics center 20 to the finished product center 30 are still delivered. The quantity of the member 11 that has not been changed is rewritten and stored in the database 39 of the finished product center 30.

  Specifically, in the server 35, based on the information written in the IC tag 22, two members 11 of the product name “a” and two members 11 of the product name “b” are placed on the first distribution cart 21 shipped from the distribution center A. 1 and two members 11 of the product name c are confirmed to be loaded, so that the quantity of the members 11 that are in stock by being delivered from the distribution center A to the finished product center 30 is shown in FIG. The data is rewritten and stored in the database 39 of the finished product center 30 as shown in FIG. That is, in the database 39 of the finished product center 30, two members 11 having a product name a and two members 11 having a product name b are present as members 11 that are delivered from the distribution center A to the finished product center 30. Is stored as one, and two members 11 of the product name c are stored.

  At this time, the server 35 compares the quantity of the members 11 requested to be delivered to each distribution center 20 and the quantity of the members 11 that are delivered from each distribution center 20 to the finished product center 30 as stock. The quantity of members 11 that have not yet been delivered from each distribution center 20 to the finished product center 30 is confirmed. Then, the quantity of the members 11 that have not yet been delivered from each distribution center 20 to the finished product center 30 is rewritten as shown in FIG. 14C and stored in the database 39 of the finished product center 30. That is, in the database 39 of the finished product center 30, as the members 11 that have not yet been delivered from the distribution center A to the finished product center 30, there are three members 11 of the product name a, two members 11 of the product name b, One member 11 of the product name c is stored.

  In this way, in the finished product center 30, the IC tag 22 attached to the distribution cart 21 shipped from each distribution center 20 is read by the IC tag reader 31 installed on the pole 32, thereby each distribution center. Whether the product name and quantity information of the member 11 delivered from the finished product center 30 to the finished product center 30 matches the product name and quantity information of the member 11 requested to be delivered from the finished product center 30 to each distribution center 20. Can be confirmed.

  Furthermore, in addition to the information shown in FIG. 14C described above, the finished product center 30 has an inventory of the finished product center 30 loaded on the logistics cart 21 as shown in FIG. 14D. The number of members 11 and the number of members 11 loaded on the sorting cart 33 are stored for each product name. In addition, the sum of the number of members 11 loaded on the distribution cart 21 and the number of members 11 loaded on the sorting cart 33 in the table shown in FIG. It is equal to the quantity of the members 11 existing as stock by being delivered from each distribution center 20 to the finished product center 30.

  As described above, when the first distribution cart 21 shipped from the distribution center A is delivered to the finished product center 30, as shown in FIG. When delivered, the quantity of the member 11 existing as stock is rewritten and stored in the database 39 of the finished product center 30. At this time, since the member 11 has not yet been loaded on the sorting cart 33, as shown in FIG. By being delivered to 30, it is rewritten to the same quantity as the quantity of the members 11 existing as stock and stored in the database 39 of the finished product center 30.

  Subsequently, the logistics cart 21 in which the IC tag 22 is read by the IC tag reader 31 installed on the pole 32 is lined up on one side of a work passage (not shown) so that the IC tag 22 attached thereto faces the work passage. Are lined up. Further, the sorting cart 33 provided for each customer 40 is moved along the work path so that the reader / writer 37 installed on the sorting cart 33 faces the logistics cart 21 (see FIG. 11).

  Then, as shown in FIG. 11, when the sorting cart 33 for P residence, which is an arbitrary customer 40, is moved to a location near where the logistics cart 21 shipped from the logistics center A is installed, FIG. As shown, wireless communication is performed between the wireless communication unit 37b of the reader / writer 37 installed in the sorting cart 33 for the P residence and the IC tag 22 attached to the distribution vehicle 21 shipped from the distribution center A. At the same time, the IC tag 22 is authenticated by the IC tag authenticating unit 37c of the reader / writer 37.

  Specifically, first, when wireless communication is started between the wireless communication unit 37b of the reader / writer 37 and the IC tag 22 attached to the logistics cart 21, a random number is generated by the IC tag authentication unit 37c. The random number is encrypted and output from the IC tag authenticating unit 37c. The cipher output from the IC tag authenticating unit 37c is transmitted to the IC tag 22 attached to the logistics cart 21 via the wireless communication unit 37b. The cipher transmitted to the IC tag 22 attached to the distribution cart 21 is decrypted by the IC tag 22, and the random number before being encrypted is confirmed. The random number confirmed by the IC tag 22 is transmitted to the IC tag authenticating unit 37c via the wireless communication unit 37b of the reader / writer 37. Then, the IC tag authentication unit 37c checks whether or not the random number generated for transmission to the IC tag 22 matches the random number sent from the IC tag 22.

  When the IC tag authenticating unit 37c confirms that these random numbers match, the IC tag authenticating unit 37c then sends the IC tag to the IC tag 22 attached to the logistics cart 21 via the wireless communication unit 37b. A signal requesting transmission of the ID inputted in advance 22 is transmitted.

  Here, in the IC tag 22 attached to the logistics cart 21, an ID consisting of the number of the logistics cart 21 and the name of the logistics center 20 is input in advance. Further, the database 39 of the finished product center 30 stores information shown in FIG. Then, in response to a request from the IC tag authenticating unit 37c, an ID preliminarily input to the IC tag 22 is transmitted from the IC tag 22 attached to the logistics cart 21 to the IC tag authenticating unit 37c via the wireless communication unit 37b. This ID is transmitted from the LAN interface 37f to the server 35 via the LAN 34. Thereafter, in the server 35, an operation is performed to confirm whether or not the ID previously input to the IC tag 22 matches the information stored in the database 39 of the finished product center 30. If it is confirmed by the confirmation work that these match in the server 35, the authentication of the IC tag 22 ends normally.

  When the authentication of the IC tag 22 by the IC tag authentication unit 37c is normally completed, a request is made from the IC tag authentication unit 37c to the wireless communication unit 37b to transmit the information written in the IC tag 22 to the loading member confirmation unit 37d. The In response to this request, wireless communication is performed between the wireless communication unit 37 b of the reader / writer 37 and the IC tag 22 attached to the logistics cart 21, and information written in the IC tag 22 is stored in the wireless communication unit 37 b of the reader / writer 37. Is sent to the loading member confirmation unit 37d and stored in the memory 37e.

  Subsequently, the information written in the IC tag 22 from the memory 37e of the reader / writer 37 is read out to the loading member confirmation unit 37d and displayed on the screen of the monitor 38. That is, on the screen of the monitor 38, as shown in FIG. 16A, the logistics cart 21 shipped from the logistics center A where the reader / writer 37 installed in the sorting cart 33 for the P residence is performing wireless communication. As the information written in the IC tag 22 attached to the product name, the name of the distribution center 20 is A, the member 11 of two product names a, the member 11 of one product name b, and two product names c It is displayed that the member 11 is provided.

  Further, as described above, the memory 37e of the reader / writer 37 stores information on the product name and quantity of the member 11 to be loaded on the sorting cart 33 (see FIG. 13), so the sorting cart 33 is stored from this memory 37e. The product name and quantity information of the member 11 to be loaded onto the sorting cart 33 and the product name and quantity information of the member 11 loaded on the sorting cart 33 are read and compared by the loading member confirmation unit 37d, and the comparison result is obtained. It is displayed on the screen of the monitor 38. That is, when the member 11 is not yet loaded on the sorting cart 33, the screen of the monitor 38 is still sorted out of the members 11 to be loaded on the sorting cart 33 for P residence as shown in FIG. As the members 11 that are not loaded on the cart 33, there are two members 11 of the product name a, two members 11 of the product name b, and one member 11 of the product name c, which are loaded on the sorting cart 33. As the member 11, it is displayed that the number of the members 11 of the product names a, b, and c is zero.

  Then, as shown in FIG. 12, when the barcode 12 of the member 11 loaded on the logistics cart 21 is read by the scanner unit 36a of the barcode reader 36, the barcode analysis unit 36b of the barcode reader 36 reads the barcode 12 The analysis is performed, and the code number of each member 11 obtained by the analysis is sent to the ID generation unit 37a of the reader / writer 37. The ID generation unit 37a of the reader / writer 37 confirms the product name from the code number of each member 11, generates a product name ID, and transmits the product name ID to the loading member confirmation unit 37d. In the loading member confirmation unit 37d, the product name is confirmed based on the received product name ID of each member 11, and the product name of this member 11 is displayed on the screen of the monitor 38. That is, the product name of the member 11 from which the barcode 12 is read is displayed on the screen of the monitor 38.

  Subsequently, the product name and quantity information of the member 11 to be loaded on the sorting cart 33 and the product name and quantity information of the member 11 loaded on the sorting cart 33 are read from the memory 37e to the loading member confirmation unit 37d. The loaded member confirmation unit 37d compares the loaded members. As a result of this comparison, when it is confirmed in the loading member confirmation part 37d that there is a member 11 that has not yet been loaded on the sorting cart 33, the product name of the member 11 that has not yet been loaded on the sorting cart 33 and A comparison is made as to whether or not the product name based on the product name ID generated by the ID generation unit 37a (that is, the product name of the member 11 from which the barcode 12 has been read) matches. On the other hand, when it is confirmed in the loading member confirmation part 37d that there is no member 11 that has not yet been loaded on the sorting cart 33, that is, it is confirmed that all the members 11 have been loaded on the sorting cart 33. On the screen of the monitor 38, “There is no member 11 to be loaded on the sorting cart 33” is displayed.

  Then, in the loading member confirmation unit 37d, it is confirmed that there is a member 11 that is not yet loaded on the sorting cart 33, and the product name of the member 11 that is not yet loaded on the sorting cart 33 based on the comparison result described above. When it is confirmed that the product name based on the product name ID generated by the ID generation unit 37a matches the product name (that is, the product name of the member 11 from which the barcode 12 is read), the barcode 12 is read. A display for loading the member 11 onto the sorting cart 33 is displayed on the screen of the monitor 38.

  That is, for example, a product name ID “α” is generated by the ID generation unit 37a for the member 11 from which the barcode 12 is read, and a product name “α” generated by the ID generation unit 37a in the loading member confirmation unit 37d. When it is confirmed from the ID that the product name of the member 11 is “a”, the content “Please load the member 11 of the product name a into the sorting cart 33 for the P residence” is displayed on the screen of the monitor 38. . Then, based on the contents displayed on the screen of the monitor 38, the member 11 having the product name a from which the bar code 12 has been read is loaded on the sorting cart 33 for P residence. At this time, a predetermined operation may be performed on the reader / writer 37 in order to indicate that the worker has loaded the member 11 having the product name a into the sorting cart 33 for the P residence.

  On the other hand, in the loading member confirmation unit 37d, it is confirmed that there is a member 11 that has not yet been loaded on the sorting cart 33, and the product name of the member 11 that has not been loaded on the sorting cart 33 based on the above-described comparison results. When it is confirmed that the product name based on the product name ID generated by the ID generation unit 37a (that is, the product name of the member 11 from which the barcode 12 has been read) does not match, “the member to be loaded” is displayed on the screen of the monitor 38. 11 is wrong "is displayed.

  Further, as described above, the product name based on the product name ID generated by the product name of the member 11 that has not yet been loaded on the sorting cart 33 in the loading member confirmation unit 37d and the ID generation unit 37a (that is, the barcode 12 is displayed). When it is confirmed that the read product name of the member 11 matches, the information written in the IC tag 22 (see FIG. 14B) is read from the memory 37e to the loading member confirmation unit 37d. Then, in the loading member confirmation unit 37d, for example, when the product name ID generated by the ID generation unit 37a is confirmed to be α, the ID α0001 is obtained from the information written in the IC tag 22 read from the memory 37e. Is transmitted from the IC tag 22 attached to the distribution cart 21 to the wireless communication unit 37b. Then, wireless communication is performed between the wireless communication unit 37 b of the reader / writer 37 and the IC tag 22, and the ID of α0001 among the IDs of the members 11 written to the IC tag 22 is deleted from the IC tag 22. Therefore, the IDs of the remaining five members 11 excluding α0001 are stored in the IC tag 22 shown in FIG.

  Further, when a signal for deleting the ID of the member 11 written in the IC tag 22 is transmitted from the wireless communication unit 37b to the IC tag 22 attached to the logistics cart 21, the loading member confirmation is performed from the wireless communication unit 37b. A signal for deleting the ID of the member 11 to be deleted from the IC tag 22 from the memory 37e is transmitted to the unit 37d. Then, the ID “α0001” is deleted from the information written in the IC tag 22 read from the memory 37e in the loading member confirmation unit 37d. At this time, since only α0002 is stored in the memory 37e as an ID having a product name ID of α, the logistic cart 21 shipped from the distribution center A is displayed on the screen of the monitor 38 as shown in FIG. The loaded member 11 of the product name a is displayed as one.

  Further, when the member 11 is loaded on the sorting cart 33 for the P residence, the product name and quantity information of the member 11 loaded on the sorting cart 33 stored in the memory 37e is rewritten. Here, when the member 11 is not yet loaded on the sorting carriage 33 for the P residence, the member 11 having the product names a, b, and c is stored in the memory 37e as the member 11 loaded on the sorting carriage 33 for the P residence. Each is stored as 0 (see FIG. 16B). However, when one member 11 is loaded on the sorting cart 33 for P residence, the product name of this member 11 is a from the product name ID of α generated by the ID generation unit 37a in the loading member confirmation unit 37d. Therefore, the member 11 of the product name a loaded on the sorting cart 33 for the P residence is counted as one and stored in the memory 37e of the reader / writer 37.

  And in the loading member confirmation part 37d, the product name and quantity of the member 11 which should be loaded into the sorting cart 33 for P residence and the product name and quantity of the member 11 which has not yet been loaded into the sorting cart 33 for P residence are compared. As a result, as shown in FIG. 17B, the screen of the monitor 38 has one member 11 of the product name a loaded on the sorting cart 33 for the P residence, and the sorting cart for the P residence. The member 11 of the product name a which has not yet been loaded on 33 is displayed as one.

  Further, when a signal for deleting the ID of the member 11 written in the IC tag 22 is transmitted from the wireless communication unit 37b to the IC tag 22 attached to the logistics cart 21, the loading member confirmation is performed from the wireless communication unit 37b. A signal for updating the information stored in the database 39 of the finished product center 30 is transmitted to the server 35 via the unit 37d. At this time, as shown in FIG. 18, the server 35 confirms the product name a and the serial number 0001 from α0001 which is the ID of the member 11 to be deleted from the IC tag 22. In 39, the member 11 composed of the product name a and the serial number 0001 is rewritten and stored in the content that it has been loaded on the sorting cart 33 for the P residence.

  At this time, the product name and quantity of the member 11 loaded on the logistics cart 21 and the product name and quantity of the member 11 loaded on the sorting cart 33 for the P residence are rewritten in the database 39 of the finished product center 30. And memorized. That is, when two members 11 of the product name a loaded on the logistics cart 21 are stored in the database 39 of the finished product center 30 (see FIG. 14D), the members of the product name a are stored in the sorting cart 33. When one piece 11 is loaded, as shown in FIG. 14 (E), there is one member 11 of the product name a loaded on the logistics cart 21, and the member 11 of the product name a loaded on the sorting cart 33 is The database 39 of the finished product center 30 is rewritten to the content of one.

  Thus, after loading the member 11 of the product name a from the distribution cart 21 shipped from the distribution center A to the sorting cart 33 for the P residence, it has not yet been loaded on the sorting cart 33 for the P residence. The member 11 is loaded. At this time, in the loading member confirmation part 37d, as the member 11 loaded on the distribution vehicle 21 shipped from the distribution center A among the members 11 not yet loaded on the sorting cart 33 for P residence, the product name a It is confirmed that there is one member 11, one member 11 with the product name b, and one member 11 with the product name c (see FIGS. 17A and 18B).

  Therefore, by performing the same operation as that for loading the member 11 from the logistics cart 21 to the sorting cart 33, one member 11 of the product name a is further added from the logistics cart 21 shipped from the logistics center A, One member 11 of the product name b and one member 11 of the product name c are extracted and loaded on the sorting cart 33 for the P residence. At this time, based on the information written in the IC tag 22 stored in the memory 37e, the ID of each member 11 such as α0002, β0001, and γ0001 from the IC tag 22 attached to the distribution cart 21 shipped from the distribution center A is obtained. It is deleted (see FIG. 9). The database 39 of the finished product center 30 includes a member 11 having a product name a and a serial number 0002, a member 11 having a product name b and a serial number 0001, and a member 11 having a product name c and a serial number 0001. Is stored in the sorting cart 33 for P residence as being loaded (see FIG. 18).

  Therefore, on the screen of the monitor 38, as the member 11 loaded on the distribution cart 21 shipped from the distribution center A, the member 11 of the product name a is 0, the member 11 of the product name b is 0, and the product name c. The member 11 is displayed as one. Further, on the screen of the monitor 38, as the members 11 loaded on the sorting cart 33 for the P residence, two members 11 of the product name a, one member 11 of the product name b, and member 11 of the product name c are displayed. Is displayed as one, and as the member 11 not yet loaded on the sorting cart 33 for P House, there are 0 member 11 of product name a, 1 member 11 of product name b, and product name c. Each member 11 is displayed as zero.

  When the member 11 is loaded from the distribution cart 21 shipped from the distribution center A to the sorting cart 33 for the P residence, the loading member confirmation unit 37d still loads the sorting cart 33 for the P residence. It is confirmed that one member 11 of the product name b that has not been loaded is not loaded on the distribution cart 21 shipped from the distribution center A. In order to inform the operator that the member 11 that has not yet been loaded on the sorting cart 33 for the P residence has not been loaded on the logistics cart 21 shipped from the logistics center A, the screen of the monitor 38 displays “This sorting cart”. 33 does not have a member 11 to be loaded ". Thereby, the loading of the member 11 from the logistics cart 21 shipped from the logistics center A to the sorting cart 33 for P residence is completed.

  Subsequently, as shown in FIG. 11, the sorting cart 33 for P residence is moved to a place where the logistics cart 21 shipped from the logistics center B is installed. Then, when the sorting cart 33 for the P residence is moved to a place near the place where the logistics cart 21 shipped from the distribution center B is placed, the reader / writer 37 installed in the sorting cart 33 for the P residence Wireless communication is performed with the IC tag 22 attached to the logistics cart 21 shipped from the logistics center B, and the same operation as that for the logistics cart 21 shipped from the logistics center A is performed (see FIG. 12). ).

  At this time, from the information of the IC tag 22 attached to the distribution cart 21 shipped from the distribution center B, the member 11 with the product name b is loaded on the distribution cart 21 shipped from the distribution center B in the loading member confirmation unit 37d. If it is confirmed that the material 11 has not been loaded, the loading of the member 11 from the distribution cart 21 shipped from the distribution center B to the sorting cart 33 for P residence is completed.

  Thereafter, as shown in FIG. 11, the sorting cart 33 for P residence is moved to the place where the logistics cart 21 shipped from the logistics center C is installed. Then, when the sorting cart 33 for the P residence is moved to a place near the place where the logistics cart 21 shipped from the distribution center C is placed, the reader / writer 37 installed in the sorting cart 33 for the P residence Wireless communication is performed with the IC tag 22 attached to the logistics cart 21 shipped from the logistics center C, and the same operation as that for the logistics cart 21 shipped from the logistics center A is performed (see FIG. 12). ).

  At this time, from the information of the IC tag 22 attached to the distribution cart 21 shipped from the distribution center C, the member 11 of the product name b is loaded on the distribution cart 21 shipped from the distribution center C in the loading member confirmation unit 37d. If it is confirmed, the member 11 of the product name “b” is loaded from the logistics cart 21 shipped from the logistics center C to the sorting cart 33 for the P residence. Then, the ID of the member 11 of this product name b is deleted from the IC tag 22 attached to the distribution cart 21 shipped from the distribution center C, and the member 11 of this product name b is stored in the database 39 of the finished product center 30. Is stored in the sorting cart 33 for P House as loaded.

  Thereafter, when it is confirmed by the loading member confirmation unit 37d that all the loading work of the member 11 to the sorting cart 33 for the P residence has been completed, the loading work such as “loading completed” on the screen of the monitor 38 is completed. The contents of are displayed. Subsequently, the worker confirms that the content indicating that the loading work of the member 11 onto the sorting cart 33 for the P residence is completed is displayed on the screen of the monitor 38, and then moves the sorting cart 33 for the P residence. Move to finished product assembly location. Then, as shown in FIG. 3, the members 11 loaded on the sorting cart 33 for the P residence at the assembly site are lowered from the sorting cart 33 and the finished product is assembled, and then the finished product center 30 is moved to the P residence. The finished product is shipped.

-Effect of Embodiment 1-
According to the present embodiment, the IC tag 22 attached to the logistics cart 21 is written by writing the ID of the member 11 loaded on the logistics cart 21 into the IC tag 22 attached to the logistics cart 21 using the RF handy writer 23. The member 11 loaded on the logistics cart 21 can be confirmed. Therefore, according to this embodiment, the member 11 distributed between a plurality of facilities can be managed for each distribution cart 21.

  Further, the IC tag reader attached to the distribution cart 21 delivered to the finished product center 30 is installed on the pole 32 by managing the members 11 distributed between a plurality of facilities for each distribution cart 21. The distribution cart 21 shipped from each distribution center 20, the member 11 loaded on the distribution cart 21, the distribution cart 21 delivered to the finished product center 30, and the member loaded on the distribution cart 21 simply by reading at 31. 11 can be confirmed. Thus, according to this embodiment, the member 11 distributed between a plurality of facilities can be accurately managed for each distribution cart 21.

<< Embodiment 2 of the Invention >>
In the second embodiment of the present invention, the configuration of the physical distribution management system according to the first embodiment is changed. Here, the difference between the present embodiment and the first embodiment will be described.

  In the physical distribution management system of the present embodiment, as shown in FIG. 19, the work path (not shown) of the finished product center 30 is partitioned into a plurality of blocks (for example, A, B, B,...). Further, as shown in FIG. 19, the pole 32 installed in the finished product center 30 is connected to the server 35 via the LAN 34 in addition to the IC tag reader 31 described in the first embodiment and the distribution cart 21. A monitor 61 is installed on which blocks (Exhibit A, Party B, Samurai, etc.) are displayed. Further, as shown in FIG. 20, the database 39 of the finished product center 30 includes the number of the logistics cart 21, the name of the logistics center 20 to which the logistics cart 21 belongs, and the member 11 loaded on the logistics cart 21. In addition to the product name and serial number and the loading state of each member 11 on the sorting cart 33, the block on which the logistics cart 21 is arranged is stored.

  In the finished product center 30 configured in this way, when the logistics cart 21 has not yet been delivered to the finished product center 30, that is, when no logistics cart 21 exists in the finished product center 30, all of the servers 35 are in the server 35. A block (A, B, B, ...) is recognized as empty. In this state, when the logistics cart 21 shipped from each logistics center 20 is delivered to the finished product center 30, the IC tag 22 attached to the logistics cart 21 is read into the IC tag reader 31 installed on the pole 32. It is. At this time, the IC tag reader 31 authenticates the IC tag 22 by performing wireless communication between the IC tag reader 31 and the IC tag 22 attached to the logistics cart 21.

  As a result, when the server 35 confirms that the information written in the IC tag 22 and the information stored in the database 28 of each distribution center 20 match, all blocks that have been recognized as empty beforehand. Any one block is selected from (A, B, B,...), And information on the selected empty block is transmitted to the monitor 61 installed in the pole 32 via the LAN 34. Then, in order to place the distribution cart 21 delivered to the finished product center 30 in an empty block, for example, “go to the block back” is displayed on the screen of the monitor 61.

  Subsequently, the operator confirms the content displayed on the screen of the monitor 61 installed on the pole 32, and presses a confirmation button (not shown) installed on the pole 32 and connected to the server 35 via the LAN 34. When pressed, a signal is transmitted from the confirmation button to the server 35. Then, it is confirmed in the server 35 that the logistics cart 21 is arranged on the block A. As a result, the number of the logistics cart 21, the name of the logistics center 20 to which the logistics cart 21 belongs, the product name and serial number of the member 11 loaded on the logistics cart 21 are stored in the database 39 of the finished product center 30. The fact that this logistics cart 21 is arranged on the block A is stored in association with it.

  In this way, as shown in FIG. 20, the first distribution cart 21 shipped from the distribution center A is in Block A, the third distribution cart 21 shipped from the distribution center B is in Block B, and the distribution center. It is assumed that the second distribution cart 21 shipped from C is stored in the block 39 and stored in the database 39 of the finished product center 30.

  Here, in the finished product center 30, an operation of reloading the members 11 loaded on the logistics cart 21 to the sorting cart 33 provided for each customer 40 is performed. At this time, as described above, wireless communication is performed between the reader / writer 37 installed on the sorting cart 33 and the IC tag 22 attached to the logistics cart 21 and the ID of the member 11 loaded on the sorting cart 33 is the ID. The member 11 having the product name and serial number transmitted to the server 35 and confirmed from the ID of the member 11 is stored in the database 39 of the finished product center 30 as loaded on the sorting cart 33 (see FIG. 20).

  Based on the information stored in the database 39 of the finished product center 30, all the members 11 loaded on the third logistics cart 21 placed in the block B and shipped from the logistics center B in the server 35, for example. When it is confirmed that it is loaded on the sorting cart 33, the block B is recognized as empty. Further, in FIG. 19, the logistics cart 21 shipped from the logistics center B arranged in the block B is indicated by a broken line to indicate that the block B is empty.

  In this state, when the logistics cart 21 shipped from each logistics center 20 is delivered to the finished product center 30, the IC tag 22 attached to the logistics cart 21 is read into the IC tag reader 31 installed on the pole 32. It is. The IC tag reader 31 authenticates the IC tag 22 by performing wireless communication between the IC tag reader 31 and the IC tag 22 attached to the logistics cart 21.

  Specifically, as described in the first embodiment, when the IC tag 22 attached to the logistics cart 21 is read by the IC tag reader 31, the information written in the IC tag 22 is transmitted to the server via the LAN 34. 35. Then, by referring to the database 28 of each distribution center 20 in the server 35, it is determined whether or not the information written in the IC tag 22 matches the information stored in the database 28 of each distribution center 20. Confirmation is performed (see FIG. 19). If it is confirmed that these match, the information that the block B is empty is transmitted to the monitor 61 installed in the pole 32 via the LAN 34. Then, in order to place the logistics cart 21 delivered to the finished product center 30 to the block B, “Go to the block B” is displayed on the screen of the monitor 61 installed on the pole 32.

  Subsequently, when the operator confirms the contents displayed on the screen of the monitor 61 and presses a confirmation button (not shown) installed on the pole 32, a signal is transmitted from the confirmation button to the server 35. Then, it is confirmed in the server 35 that the logistics cart 21 is arranged in the block B. As a result, the number of the logistics cart 21, the name of the logistics center 20 to which the logistics cart 21 belongs, the product name and serial number of the member 11 loaded on the logistics cart 21 are stored in the database 39 of the finished product center 30. The distribution cart 21 is stored in association with the block B.

  On the other hand, as described in the first embodiment, the database 39 of the finished product center 30 should be loaded with 40 customers, the number of the sorting cart 33 provided for each customer 40, and the sorting cart 33. The product name and quantity of the member 11 are stored in association with each other (see FIG. 13).

  Therefore, in the server 35, based on the information stored in the database 39 of these finished product centers 30, the sorting cart 33 proceeds to load the member 11 from the distribution cart 21 arranged in each block to the sorting cart 33. The order and the product name and quantity of the member 11 loaded from the distribution cart 21 to the sorting cart 33 in each block are calculated for each sorting cart 33. Then, this calculation result is transmitted from the server 35 via the LAN 34 to the loading member confirmation unit 37d of the reader / writer 37 installed in each sorting cart 33 and displayed on the screen of the monitor 38. That is, the screen of the monitor 38 installed in each sorting cart 33 displays the order of the blocks that each sorting cart 33 travels, and the product name and quantity of the member 11 loaded from the logistics cart 21 to the sorting cart 33 in each block. The

<< Embodiment 3 of the Invention >>
In the third embodiment of the present invention, the configuration of the physical distribution management system according to the second embodiment is changed. Here, the difference between the present embodiment and the second embodiment will be described.

  In the physical distribution management system of the present embodiment, as shown in FIG. 21, the work path of the finished product center 30 is partitioned into a plurality of blocks in a lattice shape. These blocks are composed of an area (x, y, z,...) Divided for each type of member 11 and an area (former, second, 丙,...) Divided for each place. In FIG. 21, for example, a distribution cart 21 shipped from the distribution center A to a block (hereinafter referred to as “block x-former”) composed of an area where the type of the member 11 is x and an area where the location is the former A. Indicates that it is arranged.

  In addition to the IC tag reader 31 described in the first embodiment, the pole 32 installed in the finished product center 30 is connected to the server 35 via the LAN 34 and has a block (for example, a distribution cart 21). , Block x-E) is displayed (see FIG. 19). Furthermore, as shown in FIG. 22, the database 39 of the finished product center 30 includes the number of the logistics cart 21, the name of the logistics center 20 to which the logistics cart 21 belongs, and the member 11 loaded on the logistics cart 21. In addition to the product name and serial number and the loading state of each member 11 on the sorting cart 33, the block on which the logistics cart 21 is arranged is stored.

  Further, the name of the distribution center 20 and the type of the member 11 are stored in the database 39 of the finished product center 30 in advance. That is, for example, when the type 11 member 11 from the distribution center A, the type 11 member 11 from the distribution center B, and the type 11 member 11 from the distribution center C are shipped, the types of the distribution center A and the member 11 are shipped. x is stored in association with the distribution center B and the type y of the member 11, and the distribution center C and the type z of the member 11 are associated with each other.

  In the finished product center 30 configured as described above, when the member 11 is loaded from the distribution cart 21 to the sorting cart 33, the ID of the member 11 loaded on the sorting cart 33 is transmitted to the server 35. The member 11 having the product name and serial number confirmed from the ID is loaded in the sorting cart 33 and stored in the database 39 of the finished product center 30 (see FIG. 18).

  Based on the information stored in the database 39 of the finished product center 30, for example, a block composed of an area where the type of the member 11 is y and an area where the location is the end (hereinafter referred to as “block y-end”). When the member 11 loaded on the third logistics cart 21 shipped from the logistics center B is confirmed to be loaded on the sorting cart 33, the block y-B is recognized as empty. . Further, in FIG. 21, the block y-B in which the distribution cart 21 shipped from the distribution center B is arranged is indicated by a broken line to indicate that the block y-B is empty.

  In this state, when the IC tag 22 attached to the logistics cart 21 is read by the IC tag reader 31 and the information written in the IC tag 22 is transmitted to the server 35, the server 35 writes the information in the IC tag 22. The name of the distribution center 20 is confirmed from the information, and the type of the member 11 is confirmed from the name of the distribution center 20 (see FIG. 19). For example, when it is confirmed in the server 35 that the name of the distribution center B is written in the IC tag 22 attached to the distribution cart 21, the type 11 member 11 is assigned to the distribution cart 21 from the name of the distribution center B. Is confirmed to be loaded.

  At this time, if the server 35 confirms that the information written in the IC tag 22 matches the information stored in the database 28 of each distribution center 20, information indicating that the block y-B is empty is obtained. The data is transmitted to the monitor 61 installed on the pole 32 via the LAN 34. Then, in order to place the logistics cart 21 delivered to the finished product center 30 to the block y-B, “go to block y-B” is displayed on the screen of the monitor 61 installed on the pole 32. .

  Thereafter, the operator confirms the contents displayed on the screen of the monitor 61 and presses a confirmation button (not shown) installed on the pole 32, so that a signal is transmitted from the confirmation button to the server 35 via the LAN 34. Is done. Then, in the server 35, it is confirmed that the logistics cart 21 is arranged in the block y-B. As a result, the number of the logistics cart 21, the name of the logistics center 20 to which the logistics cart 21 belongs, the product name and serial number of the member 11 loaded on the logistics cart 21 are stored in the database 39 of the finished product center 30. The fact that this logistics cart 21 is arranged in the block y-B is stored in association with it.

  On the other hand, as described in the first embodiment, the database 39 of the finished product center 30 should be loaded with 40 customers, the number of the sorting cart 33 provided for each customer 40, and the sorting cart 33.

In the fourth embodiment of the present invention, the configuration of the physical distribution management system according to the second embodiment is changed. Here, the difference between the present embodiment and the second embodiment will be described.

  In the physical distribution management system of the present embodiment, as shown in FIG. 23, the work path of the finished product center 30 is partitioned into a plurality of blocks (Exhibit A, B, B,...). Each of the plurality of blocks is provided with an IC tag reader 70 that reads the IC tag 22 attached to the logistics cart 21 and is connected to the server 35 via the LAN 34. Further, the IC tag reader 70 includes a memory (not shown) in which block names (Exhibit A, B, B,...) Are stored. Furthermore, only the IC tag reader 31 that reads the IC tag 22 attached to the logistics cart 21 is installed on the pole 32 installed in the finished product center 30.

  In the finished product center 30 configured as described above, when the logistics cart 21 shipped from each logistics center 20 is delivered to the finished product center 30, the IC tag reader 31 installed on the pole 32 is attached to the logistics cart 21. When the IC tag 22 is read, the IC tag reader 31 authenticates the IC tag 22.

  When the authentication of the IC tag 22 is normally completed, the logistics cart 21 is moved to an empty block by the operator. At this time, when the logistics cart 21 is arranged in an empty block, wireless communication is performed between the IC tag 22 attached to the logistics cart 21 and the IC tag reader 70 arranged in each block. Then, the IC tag 22 attached to the logistics cart 21 is read by the IC tag reader 70 and the information contained in the IC tag 22 is transmitted to the server 35 via the LAN 34 and stored in advance in the memory of the IC tag reader 70. The name of the block thus obtained is transmitted to the server 35.

  Here, as described in the first embodiment, the IC tag 22 attached to the logistics cart 21 includes the number of the logistics cart 21, the name of the logistics center 20 to which the logistics cart 21 belongs, and the logistics cart. The ID of the member 11 loaded in 21 is written (see FIG. 9). Therefore, in the server 35, the information written in the IC tag 22 is associated with the block name and stored in the database 39 of the finished product center 30.

In the server 35, the product name is confirmed from the ID of each member 11 as information written in the IC tag 22, and the type of the member 11 is confirmed from the product name. The area where the same type of member 11 is arranged may be displayed on the screen of the monitor 61 as an empty area.

  In addition, while the logistics cart 21 is arranged in each block, wireless communication is continuously performed between the IC tag reader 70 installed in each block and the IC tag 22 attached to the logistics cart 21. Then, after all the members 11 loaded on the logistics cart 21 are transferred to the sorting cart 33, the IC tag reader 70 and the IC attached to the logistics cart 21 are moved when the empty logistics cart 21 is moved from each block. Wireless communication with the tag 22 is interrupted.

  For this reason, when the monitor 61 which displays an empty block on the pole 32 is installed, the wireless communication between the IC tag reader 70 installed in each block and the IC tag 22 attached to the logistics cart 21 is interrupted. Sometimes, by causing the server 35 to recognize that the block is empty, this block is displayed as empty on the screen of the monitor 61 after the empty logistics cart 21 is moved from each block. With such a configuration, when the logistics cart 21 loaded with the members 11 is arranged in an empty block, it is possible to reliably prevent the empty logistics cart 21 from being left in that block.

  Further, the IC tag reader 31 installed on the pole 32 may also be used as the IC tag reader 70 installed on each block. That is, when the distribution cart 21 delivered from each distribution center 20 is arranged in each block, wireless communication is performed between the IC tag 22 attached to the distribution cart 21 and the IC tag reader 70 installed in each block. The IC tag 22 may be authenticated by the IC tag reader 70.
