Description

  The present invention takes out a container containing a target book from a plurality of containers accommodated in the library and transports it to the station, and transports the container from the station to the library after lending or returning the books. The present invention relates to a book storage management system.

  In a conventional book storage management system, a wireless tag storing a book code (identification information) is attached to each book, and each book is stored in a container that is transported in the left-right direction, which is the transport direction. The spine covers are arranged in two rows in the thickness direction (front-rear direction) so that the spine covers face each other. Furthermore, a tag reader / writer (tag reader) for performing wireless communication with the wireless tag is arranged in parallel along the transport direction on one side of the transport conveyor that transports the container to the station. Some books are read from the wireless tag of each book (for example, refer to Patent Document 1).

And can be appropriately operated. That is, the station 11 constitutes a management device according to the present invention.

  Next, the container 6 in which the book 4 is accommodated will be described. As shown in FIGS. 6 to 8, the container 6 is made of a resin material such as polypropylene. The container 6 includes a bottom plate 6a, a first side wall 6b extending upward from left and right ends of the bottom plate 6a, and a second side wall 6c extending upward from front and rear ends of the bottom plate 6a. And is formed in a substantially box that opens upward.

  The first side wall 6b is formed to be longer in the vertical direction than the second side wall 6c. The inside of the container 6 surrounded by the first side wall 6b and the second side wall 6c serves as an accommodation space 21 for accommodating a plurality of books 4.

  As shown in FIG. 8, the bottom plate 6 a is formed on an inclined surface 6 d that forms an inclination of an angle θ upward from the second side wall 6 c provided on the front and rear of the bottom plate 6 a toward the center in the front-rear direction of the container 6. ing. As shown in FIG. 6, the center in the front-rear direction of the bottom plate 6a is formed in a rectangular horizontal plane 6e in plan view between the first side walls 6b provided on the left and right sides of the bottom plate 6a, and the front and rear inclined surfaces 6d is connected to the front and rear end edges of the horizontal surface 6e.

  The outer edge of the upper end of the second side wall 6c is formed in a notch 6f that is recessed toward the inside of the container 6 from the outer surface of the second side wall 6c. The side surface 6g is formed with an inclination of an angle θ which is the same inclination angle as the inclined surface 6d toward the outer side in the front-rear direction of the container 6 from the lower end portion upward. Therefore, the angle formed by the inner side surface 6g of the second side wall 6c and the inclined surface 6d of the bottom plate 6a becomes a right angle, and the corner portion of the book 4 can be held.

  In the present embodiment, the angle θ between the inclined surface 6d and the inner side surface 6g is formed at about 2 degrees, but it must be an angle at which the book 4 accommodated in the container 6 drops out of the accommodation space 21. For example, the angle θ is not particularly limited.

  Further, in the container 6, a partition wall 6h is erected upward from a substantially horizontal center of the bottom plate 6a between the front and rear second side walls 6c, and the storage space 21 is partitioned into left and right by the partition wall 6h. It is done.

  Further, a slit 6i that opens toward the upper side and the inner side of the container 6 is formed at a substantially central portion in the front-rear direction of the first side wall 6b. Each of the slits 6i is provided with a plurality of strips (five strips in the present embodiment) in the front-rear direction so as to oppose each other between the first side walls 6b.

  Between the two pairs of slits 6i facing in the left-right direction of these five sets, the two magnetic plates 22 as a partitioning portion in the present invention that partitions the housing space 21 into the front side and the back side across the partition wall 6h Can be inserted through.

  The two magnetic plates 22 are made of a metal material such as a steel material or an iron material, that is, a magnetic member. Note that a magnetic sheet such as a ferrite sheet may be attached to the magnetic plate 22. If the ferrite sheet is attached, the RFID tag 7 may be in contact with the magnetic plate 22. The identification information of the RFID tag 7 can be read by the first and second tag readers 15 and 16.

  Furthermore, a plurality of unillustrated fitting pieces extending in the left-right direction extend downward at the lower end of the magnetic plate 22. These fitting pieces can be fitted into a plurality of elongated holes 6k provided in a plurality of strips facing the horizontal plane 9 in the left-right direction when the left and right ends of the magnetic plate 22 are inserted through the slits 6i. Therefore, the two magnetic plates 22 can be fixed by fitting the fitting pieces into the long holes 6k while inserting the left and right end portions into the slit 6i from above.

  The books 4 accommodated in the container 6 in the accommodation space 21 divided into the front side and the back side of the container 6 by these magnetic plates 22 are in a state in which the spine 4a is directed outward in the front-rear direction of the container 6. Thus, they are accommodated in a state where they are arranged in the left-right direction, which is the thickness direction of the book 4.

  The container 6 configured as described above and accommodates the book 4 is based on a command from the station 11 as the user operates the touch panel 19 when the user lends or returns the book 4 as described above. Then, it is conveyed from the bookcase 5 of the closed library 3 to the center of the hollow portion 12 in the station 11 via the stacker crane 8 and the conveyor 9 (see FIG. 1).

  As shown in FIG. 4, when the container 6 is transported to the center of the hollow portion 12 in the station 11, the first and second tag readers 15, 16 provided on the front side and the back side of the conveyor 9. By passing between, the identification information of the RFID tag 7 of the book 4 in the container 6 is read by the first and second tag readers 15 and 16.

  Specifically, when the conveyor 9 transports the container 6 from the right to the hollow portion 12 in the station 11, the first and second tag readers 15 and 16 are moved to the left end portion (tip portion) in the transport direction of the container 6. The identification information is sequentially read from the RFID tag 7 of the book 4 from the book 4 accommodated on the side) to the book 4 accommodated on the right end (terminal) side in the transport direction of the container 6.

  As described above, the book 4 according to the present invention is along the reading direction in which the first and second tag readers 15 and 16 read the RFID tag 7 with the spine 4a facing the front side and the back side of the container 6. The storage spaces 21 of the containers 6 are accommodated side by side.

  The first tag reader 15 uses, as an electromagnetic wave for reading identification information from the RFID tag 7, linearly polarized waves having a constant vibration direction in a state where a magnetic field and an electric field are orthogonal to each other. Therefore, as shown in FIG. 6, the first tag reader 15 has the RFID tag 7 of the adjacent book 4 because the back cover 4 a of the book 4 accommodated in the container 6 is not accommodated in the same plane. Even if there is a slight deviation in the distance from the first tag reader 15, the identification information can be read from each RFID tag 7.

  The linearly polarized waves are classified into horizontal polarized waves in which the vibration direction of the electric field is horizontal with respect to the ground, and vertical polarized waves in which the vibration direction of the electric field is perpendicular to the ground. Either of them may be used as long as the identification information can be read from the tag 7.

  On the other hand, the second tag reader 16 synthesizes the horizontal polarization and the vertical polarization described above as the electromagnetic waves for reading the identification information from the RFID tag 7 with the phase shifted by 1 / 2π, and the magnetic field and the electric field rotate with time. Use polarization. Since this circularly polarized wave can be received not only in the horizontally polarized wave and the vertically polarized wave but also in the polarization direction in which the electric field is directed in an oblique direction, it can be received from the RFID tag 7 without depending on the direction of the RFID tag 7. The identification information can be read.

  Therefore, as shown in FIGS. 6 and 7, the second tag reader 16 can also read the identification information from the RFID tag 7 of the book 4 accommodated in a state where the second tag reader 16 is lying on its side in the container 6.

  The station 11 compares the identification information read by the first tag reader 15 and the second tag reader 16, and when the identification information that has not been read by one tag reader is read by the other tag reader, The identification information read by the first tag reader 15 and the second tag reader 16 is complemented by grasping the reading order of the identification information not read by one tag reader from the identification information before and after being read. Furthermore, the identification information read by the first tag reader 15 may be given priority over the second tag reader 16.

  In the present embodiment, as described above, the first tag reader 15 is arranged closer to the container 6 than the second tag reader 16, and as shown in FIG. However, the linear distance between the first tag reader 15 and the RFID tag 7 of each book 4 is sufficient for identifying information even if linear polarization is used. Is set to a readable distance.

  Furthermore, since the storage space 21 of the container 6 is divided into a front side and a back side by a magnetic plate 22 constituted by two magnetic members, first and second provided on the front side of the conveyor 9. The tag readers 15 and 16 can read the identification information only for the RFID tag 7 of the book 4 accommodated on the front side of the accommodation space 21. Similarly, the first and second tag readers 15 and 16 provided on the back side of the conveyor 9 are limited to the RFID tag 7 of the book 4 accommodated on the back side of the accommodation space 21 and read the identification information. It is possible.

  In this embodiment, as described above, the station 11 can be used by sequentially reading the identification information from the RFID tag 7 of the book 4 accommodated in the container 6 by the first and second tag readers 15 and 16. It is possible to estimate at which accommodation position the book 4 intended by the person is placed in the accommodation space 21 of the container 6.

  Specifically, first, the user operates the touch panel 19 to input identification information such as the title of the target book 4 and the author, and transports the container 6 in which the target book 4 is accommodated. The operation instruction is performed as follows.

  Based on this transport instruction, the station 11 moves the container 6 containing the user's intended book 4 from the bookcase 5 in the closed library 3 to the stacker crane 8 and the conveyor 9 in the hollow space in the station 11. Control is performed to transport to the center of the section 12.

  And when the container 6 is conveyed toward the center of the hollow part 12 in the station 11, the front of the container 6 is provided by the first and second tag readers 15 and 16 provided on the front side and the back side of the conveyor 9. The identification information of the RFID tag 7 of the book 4 accommodated in the accommodation space 21 between the side and the back side is sequentially read.

  As shown in FIG. 9, the station 11 displays the title of the book 4 as the identification information on the display device 18 based on the sequentially read identification information. Specifically, the identification information of the book 4 read by the first and second tag readers 15 and 16 provided on the front side of the conveyor 9 is stored on the counter side (front side) of the storage space 21 of the container 6. It is displayed on the display device 18 as the title of the book 4 that is being stored. Similarly, the identification information of the book 4 read by the first and second tag readers 15 and 16 provided on the back side of the conveyor 9 is stored in the back side (back side) of the storage space 21 of the container 6. 4 on the display device 18.

  Further, the station 11 collates the identification information read by the first and second tag readers 15 and 16 on the front side and the back side of the conveyor 9 with the identification information of the book 4 intended by the user, and displays the display device. The title of the book 4 intended by the user is lit up among the titles of the book 4 displayed in 18.

  In this manner, the title of the book 4 accommodated in the accommodation space 21 of the container 6 is displayed on the display device 18 in the order read by the first and second tag readers 15 and 16, so that the user can accommodate the container 6. The accommodation position of the target book 4 in the space 21 can be grasped. That is, the station 11 in the present invention constitutes the estimation means in the present invention. Further, the display device 18 according to the present invention constitutes a notification means according to the present invention.

  As shown in FIG. 9, when the book 4 intended by the user is stored on the back side of the storage space 21 of the container 6, the user presses the container rotation button 11a. The target book 4 can be easily taken out from the container 6 by rotating the turntable 13 and changing the direction of the container 6.

  The book 4 taken out from the storage space 21 of the container 6 can be lent by causing the tag reader 20 for rent to read the identification information from the RFID tag 7.

  Then, after the user's lending of the book 4 is completed, the user operates the touch panel 19 again to give an operation instruction to return the container 6 from the station 11 to the book shelf 5 of the closed library 3. The station 11 controls the stacker crane 8 and the conveyor 9 to return the container 6 to the bookshelf 5 based on this operation instruction.

  Furthermore, the first and second tag readers 15 and 16 provided on the front side and the back side of the conveyor 9 are accommodated in the accommodation space 21 between the front side and the back side of the container 6 conveyed toward the closed library 3. The identification information is read again from the RFID tag 7 of the book 4 accommodated. By doing in this way, the identification information read from the book 4 accommodated in the accommodation space 21 of the container 6 conveyed from the station 11 toward the closed library 3, and the book shelf 5 of the closed library 3 toward the station 11. The identification information read from the book 4 accommodated in the accommodation space 21 of the container 6 to be conveyed is compared, and whether or not there is the book 4 taken out from the container 6 other than the book 4 lent out to the user is determined. Can be managed.

  In this embodiment, the same conveyor 9 is used when the container 6 is transported from the book shelf 5 of the closed library 3 to the station 11 and when the container 6 is transported from the station 11 to the book shelf 5 of the closed library 3. However, the station 11 may be another modified example.

  The modified station 11 will be described. As shown in FIG. 10, in the modified station 11, in addition to the conveyor 9 described above, the book shelf of the closed library 3 from the left side of the turntable 13 of the hollow portion 12 of the station 11. A return conveyor 9 ′ is extended toward 5.

  When the container 6 is returned and conveyed from the station 11 to the book shelf 5 of the closed library 3, the container 6 is conveyed by the conveyor 9 '. The station 11 of this modified example is provided with a pair of first and second tag readers 15 and 16 on the front side and the back side of the return conveyor 9 ', and is accommodated in the container 6 being returned. The identification information can be read from the RFID tag 7 of the book 4 being recorded.

  As described above, in the book storage management system 1 according to the present embodiment, the first tag reader 15 that can read the identification information of the RFID tag 7 using linear polarization, and the identification information of the RFID tag 7 using circular polarization. The second tag reader 16 can read the identification information, and the container 6 and the first and second tag readers 15 and 16 are moved relative to each other so that the first and second tag readers 15 and 16 sequentially identify the identification information. When the first and second tag readers 15 and 16 are used together with linearly polarized waves and circularly polarized waves having different properties, the identification information is missed from the RFID tag 7 by one of the polarized waves. However, the identification information can be read from the RFID tag 7 by the other polarized wave, and it is not related to the relative moving speed between the container 6 and the first and second tag readers 15 and 16. , It is possible to sequentially read the identification information from the RFID tag 7 accurately by the first and second tag reader 15.

  Note that the circularly polarized wave is generated from the RFID tag 7 even when the distance from the second tag reader 16 to the RFID tag 7 is long, or even when the book 4 is accommodated in the container 6 in a lying state. The identification information can be read, and the linearly polarized wave can read the identification information from the RFID tag 7 even when the distance from the first tag reader 15 to the RFID tag 7 is slightly different. If the first and second tag readers 15 and 16 are used in combination, the identification information can be accurately obtained from the RFID tag 7 by the circularly polarized wave and the linearly polarized wave even when the book 4 is randomly stored in the container 6. Can be read.

  Also, since the container 6 is moved horizontally, the identification information of the RFID tag 7 is sequentially read by the first and second tag readers 15 and 16, and therefore when the container 6 is transported from the closed storage 3 to the station 11. The identification information can be read from the RFID tag 7 by the first and second tag readers 15 and 16 without stopping the conveyance of the container in both cases when the container 11 is transported from the station 11 to the closed library 3 after the return work. Therefore, the conveyance efficiency of the container 6 can be improved.

  Further, since the first tag reader 15 reads the identification information closer to the container 6 than the second tag reader 16, the first tag reader 15 using linearly polarized waves is more than the second tag reader 16 using circularly polarized waves. Since the distance at which the identification information of the RFID tag 7 can be read is short, the arrangement positions of the first and second tag readers 15 and 16 are shifted back and forth while improving the reading accuracy of the first tag reader using linearly polarized waves. be able to.

  The plurality of books 4 have an RFID tag 7 attached to the back cover 4a. The plurality of books 4 have the back cover 4a facing outward, and the first and second tag readers 15 and 16 Since they are accommodated in the container 6 in a state of being arranged along the reading direction, the first and second tag readers 15 and 16 and the RFID tag 7 are arranged to face each other, and the first and second tag readers 15, 16 makes it easy to read the identification information from the RFID tag 7, and when the user searches for the target book 4 from the container 6, the user can easily check the target book 4 by visually checking the spine 4 a.

  Next, a book storage management system according to the second embodiment will be described with reference to FIG. It should be noted that the same components as those shown in the above-described embodiment are denoted by the same reference numerals and redundant description is omitted. Hereinafter, the lower side of the sheet of FIG. 11 will be described as the front side (front side) of the station and the container.
