Description

  The present invention relates to a book storage management apparatus and a book storage management method suitable for use in, for example, a large library that stores a large amount of books.

  As is well known, in recent years, a large library or the like having a large amount of collections tends to adopt a closed library system with high book storage efficiency. And in order to improve the efficiency of the work required for taking out and returning books to such a closed library, automatic storage / exit systems have been introduced.

  This automatic loading / unloading system takes out the book requested for lending from the library and transports it to the counter, deletes the lending registration for the book that has been lended for the book, and returns the book to the library. Thus, the operation of recording the storage position and the like are automated so that the books can be taken out and returned to the closed library accurately and quickly.

  That is, in this type of automatic loading / unloading system, each book is provided with a barcode, a wireless tag, or the like in order to facilitate management of a large amount of books stored. Each book is stored in a container for each of a plurality of books, and is stored in and out of the library in units of containers.

  When a book is requested to be taken out (rented), the container containing the book is automatically delivered from the library and transported to the station, and the librarian requests the container from among the containers transported to the station. The book is taken out, a bar code label attached to the book, an RFID tag, or the like is read and delivered to the user, where the book is lent out.

  When the return of the book is requested, the container that should accommodate the returned book is automatically issued from the library and taken out to the station. The librarian reads the barcode label or RFID tag attached to the book, stores the returned book in the container taken out to the station, and then moves the container into the library, where the book is returned. Is done.

  By the way, if you do the reading / unloading work without reading, it means that there is no actual book in the container at the time of retrieval, and there is a book on the data. There will be unmanaged books.

  In particular, if this case occurs at the time of return, it will become an unknown book, and searching for this book in the free location method operated by the automated library system will require enormous effort and labor as the amount of books stored increases. Searching for books is almost impossible.

  As a preventive measure, it is required that no mistakes are made at the time of book entry / exit work, but since it is a human operation, there is no guarantee that 100% mistakes will not be made.

  Patent Document 1 describes that an alarm is issued if an attempt is made to deliver a barcode label to a container without reading the barcode label attached to the book.

  Patent Document 2 shows that a bar code label attached to a book is read by a tag reader.

JP 2002-338011 A JP 2003-118812 A

  However, in Patent Document 1, although it is confirmed whether or not the barcode of the book has been read, it is not described whether the book is put in the container and then whether or not the book is canceled.

  Also, Patent Document 2 does not describe whether a book is put in a container or whether it is canceled after that.

  An object of the present invention is to provide a book storage management apparatus and a book storage management method capable of reliably recognizing whether a librarian has put a book in a container or stopped the book.

  In the book automatic management system configured as described above, the characteristic processing operation will be described below with reference to the flowcharts shown in FIGS. That is, the books 13 are taken out and returned to the container 12 held in the container discharge unit 22b of the second-floor station 22 and the container discharge units 24b and 25b of the first-floor stations 24 and 25.

(Removal process)
First, description will be made regarding a case where the book 13 is taken out from the container 12 held in the container discharge unit 22b of the station 22 on the second floor by using the flowchart of FIG.

  First, at the station 22 on the second floor, the librarian inputs the title of the book from the display panel 35 of the touch panel in accordance with the desire of the library user, and transfers the container 12 on which the desired book is placed to the conveyor. Call up to station 22 on the second floor with 17 etc. (step S11). The librarian places his hand in the opening 34 a and takes out the corresponding book from the container 12. The control unit of the management computer 46 detects a weight reduction signal from the weight sensor 39 (step S12), and then, within a predetermined time (for example, 3 seconds), the gate-type wireless tag reader / writer 37 or the counter base When the RFID tag 33 or barcode book code is read from the RFID tag reader / writer 37a (or barcode reader 65 or the like) placed flat on the card (step S13), it is determined that the corresponding book has been taken out from the container 12. To do. When the corresponding book is taken out, it is registered in the hard disk 51 or the like as storage means (step S14). However, the control unit of the management computer 46, within a predetermined time, from the wireless tag reader / writer 37a (or the barcode reader 65 or the like) placed flat on the gate-shaped wireless tag reader / writer 37 or the counter stand, If the barcode book code is not read (step S13), it is determined that the book has been returned to the container 12 again, and it is determined that the librarian's take-out registration operation error has occurred. In S15, it is displayed on the display panel 35 that it is an extraction / registration operation mistake, and the processing is terminated after prompting the librarian to confirm or extract / register. Here, after detecting that the weight is reduced, it is possible to determine whether or not the take-out registration operation has been performed within a predetermined time, thereby preventing a registration operation error.

  Further, in this way, the gate-like wireless tag reader / writer 37 is provided in the opening 34a in a gate-like manner, and further, by monitoring the change in the weight of the container 12, the operation error of the librarian is eliminated, and the book is surely confirmed. Detect and register removal.

  Furthermore, the case where the extraction process of the book 13 is performed using the procedure of the flowchart of FIG. 10 will be described. In this procedure, steps S11 to S13 are the same as those in the flowchart of FIG. However, the control unit of the management computer 46 detects the weight loss by the weight sensor 39 in step S12, and when the wireless tag 33 or the barcode book code is detected in step S13, The book code is registered in the hard disk 51 or the like as the storage means as having been extracted. In step S13, when the control unit of the management computer 46 detects an increase in weight without detecting the wireless tag 33 or the barcode within a predetermined time (for example, 3 seconds) (step S17), the corresponding computer is extracted. Registration is canceled from the hard disk 51 or the like as the storage means (step S18). If the control unit of the management computer 46 does not detect the wireless tag 33, the barcode, or the weight increase within a predetermined time (for example, 3 seconds), the control unit 46 determines that the librarian's take-out registration operation error and step S19. Then, it is displayed on the display panel 35 that it is an extraction / registration operation mistake, and the process is terminated after prompting the librarian to confirm or extract / register. As described above, the procedure of the flowchart of FIG. 10 can also be used to prevent the librarian's operation error and register the book retrieval process very reliably.

(Return processing)
Next, a case where the return processing of the book 13 is performed on the container 12 held in the container discharge unit 22b of the station 22 on the second floor will be described using the flowchart of FIG.

  First, at the station 22 on the second floor, the librarian has a kind of size corresponding to the size of the book for returning the book from the display panel 35 of the touch panel according to the desire of the library user. The container 12 is called up to the station 22 on the second floor by the transfer conveyor 17 or the like (step S21). Next, the librarian inserts the book received from the library user through the opening 34a and places it in the container 12 that is called and held. The control unit of the management computer 46 reads out the wireless tag 33 and the barcode book code from the gate-shaped wireless tag reader / writer 37 or the wireless tag reader / writer 37a (or the barcode reader 65) placed flat on the counter stand ( In step S22), when a signal indicating an increase in the weight of the container 12 from the weight sensor 39 is detected within a predetermined time (step S23), it is determined that the corresponding book has been returned to the container 12. When the corresponding book is returned, it is registered in the hard disk 51 or the like which is a storage means (step S24). However, in step S23, the control unit of the management computer 46 does not detect a weight increase within a predetermined time (for example, 3 seconds) or increases the weight without detecting the wireless tag 33 or the barcode. If it is detected (step S25), it is determined that the librarian's return registration operation error has occurred, and in step S26, the return registration operation error is displayed on the display panel 35, and the librarian is prompted for confirmation or return registration operation. The process ends. Here, it is possible to determine whether or not an increase in weight has been detected after the detection of the wireless tag or barcode, and whether or not the detection of the wireless tag or barcode has been performed when there is an increase in weight. By doing so, it is possible to prevent registration operation mistakes.

  Further, in this way, the gate-like wireless tag reader / writer 37 is provided in the opening 34a in a gate-like manner, and further, by monitoring the change in the weight of the container 12, the operation error of the librarian is eliminated, and the book is surely confirmed. Detect return and register.

  Furthermore, the case where the return process of the book 13 is performed using the procedure of the flowchart of FIG. 12 will be described. In this procedure, steps S21 to S26 are the same as those in the flowchart of FIG. However, the control unit of the management computer 46 detects the book code of the wireless tag 33 or the barcode in step S22, and when the weight sensor 39 detects an increase in weight in step S23, the book of the corresponding book in step S24. The code is registered in the hard disk 51 or the like as a storage means as having been returned. In addition, when the control unit of the management computer 46 detects weight loss within a predetermined time (for example, 3 seconds) (step S27), it cancels the registration of the return of the corresponding book from the hard disk 51 or the like as the storage means. (Step S28). However, if the control unit of the management computer 46 does not detect weight loss within a predetermined time (for example, 3 seconds), the registration for returning the corresponding book is confirmed. In this way, the procedure of the flowchart of FIG. 12 can also prevent the librarian's operation mistake and register the book retrieval process very reliably.

  In the above-described embodiment, the second-floor station 22 has been described. However, in the embodiment according to the present invention, other stations have the same operational effects by the same operation.
