DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic book sorting apparatus suitable for use in, for example, a large library for storing a large amount of books, and more particularly to a method for returning many kinds of books having different sizes and paper qualities. The present invention relates to a device for improving the efficiency of required work.

[0002]

2. Description of the Related Art As is well known, in recent years, in a large-scale library or the like having a large collection of books, a bar code label for identification is attached to each of all books stored therein.
A book management system has been introduced in which the barcode and book name are associated with each other and registered in a book file of a computer, thereby performing comprehensive storage management of all books.

[0003] In a library in which such a book management system is introduced, a user card in which an identification code or the like for each individual is magnetically recorded is distributed to all users who request a book to be lent. In this case, the association between the identification code recorded on the user card and the barcode of the book requested to be borrowed is performed to manage the lending and return of the book.

[0004] Specifically, when lending a book,
The librarian reads the bar code label of the requested book using a bar code reader, reads the identification code of the user card submitted by the user with a magnetic card reader, and uses the bar code and the identification code as rental data. Input to computer. Then, the computer associates the input barcode with the identification code and registers it in the lending file, and the book lending procedure is completed here.

When returning a book, a librarian reads a barcode label of the returned book with a barcode reader, and inputs the read barcode to a computer as return data. Then the computer
The registration of the rental file corresponding to the input barcode is deleted, and the book return procedure is completed. After that, the librarian sorts the returned books according to classification or open / closed and returns them to the library.

By the way, in such a book management system, each time a book is returned, a librarian is required to carry out a return procedure on a computer or to sort books whose return procedure has been completed. It is necessary to perform repetitive work. For this reason, when the number of books to be returned increases, the frequency of the work required by the librarian to return the books increases, so that there is a disadvantage that the work load of the librarian increases when combined with other tasks.

Therefore, recently, in order to improve the efficiency of book return work by automating the work of returning procedures and sorting work for a large number of books, for example, Japanese Patent Application Laid-Open No. Hei.
A book sorting system as shown in No. 46164 has been considered. This book sorting system reads the barcode of the book and performs the return procedure by inserting the book to be returned into a predetermined book slot, and then handles the books for which the return procedure has been completed by classification. It is sorted by selectively storing it in a plurality of book stacking boxes installed.

However, this type of book sorting system is still in the process of being developed, and there is much room for improvement in various points. In particular, books
Even if they belong to the same classification, there are very many types according to, for example, size, thickness, paper quality, and the like. For this reason, even if books of any kind are mixed, sorting can be performed accurately and quickly without damaging each book, and furthermore, in order to make the configuration even simpler, the details have to be reduced. There is a strong demand for improvements.

[0009]

As described above, in the current book sorting system in which the book return procedure and the sorting work are automated, various kinds of books having different sizes, thicknesses, and paper qualities are used. Even if they are mixed, it is important to improve the details in detail so that the books can be sorted accurately and quickly without damaging each book, and the structure can be further simplified. It has become a challenge.

Therefore, the present invention has been made in view of the above circumstances, and enables accurate and quick sorting work to be performed on many types of books having different sizes and paper qualities without damaging them. , Which can further improve the efficiency of book return work and has a simple configuration
It is an object of the present invention to provide a very good automatic book sorting apparatus which can promote downsizing .

[0014]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows the overall configuration of the book automatic sorting system described here. First, generally speaking, reference numeral 11 in the figure denotes an input receiving unit for automatic book return, which is installed, for example, near a user counter (not shown) in a library. Then, the user simply inserts the book to be returned (not shown) into the input receiving unit 11 in the designated direction.
Books can be returned automatically without the need for librarians.

That is, the books loaded into the loading receiving section 11 are loaded on the transport conveyor 13 through the shooter 12. The transport conveyor 13 transports the books discharged from the chute 12 to the sorting tray 14. In this case, while the book is being conveyed by the conveyor 13, the barcode attached to the book is read, and the book return procedure is completed.

The sorting tray 14 receives the books conveyed by the conveyor 13 and sorts the books automatically, for example, by classification.
Leading to. That is, the sorting mechanism 15 has a plurality of (twelve in the illustrated case) pedestals 16, 16,... Arranged at regular intervals in a substantially elliptical loop shape. The plurality of receiving tables 16, 16,... Are cyclically moved by the receiving table transport mechanism 17 in the direction indicated by the arrow in the figure along the arranged loop shape.

In this case, a plurality of cradles 16, 16,...
Is sequentially moved to a position corresponding to the carry-out port 14a of the sorting cradle 14 by being cyclically moved by the cradle transfer mechanism 17. And
The books received by the sorting pedestal 14 are guided to the cradle 16 which has been moved to a position corresponding to the carry-out port 14a of the sorting cradle 14, and are loaded.

Each of the plurality of cradles 16, 16,... Respectively corresponds to ten cradles 16, 16,. , Book collecting boxes 18, 18,... Are installed. These plurality of book stacking boxes 18, 18,...
Each of them can accommodate a plurality of books of different classifications.
When the book is moved cyclically, the book is
It is moved from 6 and accommodated.

For this reason, the books to be returned, which have been input into the input receiving section 11, are returned to the outlet 14a of the sorting tray 14 after the return procedure is completed while being transported by the transport conveyor 13. Is mounted on the empty cradle 16 which has already been circulated and moved to a position corresponding to the above. In a state where the receiving table 16 is circulated and moved to a position corresponding to the book stacking box 18 in which the loaded books are to be stored, the receiving table 1 is
The books loaded in 6 are transferred to the book stacking box 18, where the returned books are sorted by classification.

As described above, the returned books are stored in a plurality of book bins 18, 18,
Since the documents are automatically sorted into..., The librarian does not need to perform the return procedure and sort the returned books each time the book is returned. In other words, the librarian only needs to return the books stored in the full book bins 18, 18,... To the bookshelf corresponding to the classification, thereby further improving the efficiency of the book return operation. Can be improved.

The plurality of book bins 18, 18,
.. Are provided with operation boxes 19, 19,. These operation boxes 19, 19,...
.. Perform the operation of identifying whether the book stacking boxes 18, 18,... Are in the set state where they are set at the predetermined positions or in the reset state where they are removed from the predetermined positions. The set state and the reset state of the boxes 18, 18,... Are recognized by a control system described later.

Next, a detailed configuration of each unit of the book sorting system described above will be described. First, FIG. 2 shows the input receiving unit 11. The input receiving unit 11 includes:
For example, a message monitor 11a including an LED (light emitting diode) character display or the like is provided. The message monitor 11a displays various messages to the user who returns the book. The contents of this message include various expressions for the convenience of the user, such as "I can return it,""Please wait for insertion," and "Please insert it with the barcode label on the book." It is prepared.

The input receiving section 11 has a book slot 1 for a user to actually input a book to be returned.
1b is formed. In addition, the input receiving unit 11 includes a book return port 11c for returning a book whose barcode could not be read out of the books input to the book input port 11b to the user, and a book return port 11c. 11c
And a receiving port 11d for receiving the book returned from.

The receipt receiving unit 11 further includes a receipt receipt issuance unit 11e for issuing a receipt to the user when the process of returning the book inserted into the book slot 11b is completed. Is installed.
In addition, this receipt is displayed on the operation button 11f by the user.
By operating, a book for which the return procedure has been completed at that time is issued.

As shown in FIG. 3, the book 20 has a bar code label 2 for identification of the book 20 at a lower right corner or the like in the cover 20a as a specified range in the cover 20a.
0b is stuck. The book 20 is provided with a magnetized piece 20d for preventing unauthorized removal of the book 20 on the side of the cover 20a close to the spine 20c. This magnetized piece 20d
Is demagnetized when the book 20 is lent out through a regular lending procedure, and is magnetized when it is returned.

FIG. 4 shows the relationship among the input receiving section 11, the shooter 12, the transport conveyor 13, the sorting tray 14, and the tray 16. First, when the book 20 is inserted into the book insertion slot 11b of the insertion receiving unit 11, does the book 20 protrude from the inside of the shooter 12 by the protrusion detector 12b installed near the entrance 12a of the shooter 12? No is detected. In this case, when it is determined that the book 20 protrudes from the shooter 12, for example, a message indicating that the user is instructed to reinsert the book 20 is displayed by the message monitor 11a.

The book 20 correctly inserted into the book slot 11b without protruding from the inside of the shooter 12 is inserted through the shooter 12 installed at a predetermined downward inclination.
The outlet 12c is stopped by being locked by a stopper 12d that closes the outlet 12c. The stopper 12d is provided so as to be able to open and close the outlet 12c of the shooter 12 by transmitting the rotational force of the opening / closing motor 12e via the rod mechanism 12f. The opening / closing motor 12e includes a closed position detector 12g and an open position detector 12h for detecting that the stopper 12d has reached the closed position and the open position, respectively.
The rotation operation is controlled based on the detection result.

Then, the book 20 is attached to the stopper 12d.
Is locked, the book detector 12i installed near the exit 12c of the shooter 12 detects the presence of the book 20 and controls the opening / closing motor 12e so as to move the stopper 12d to the open position. For this reason, the book 20 is discharged from the outlet 12 c of the chute 12 and is placed on the transport conveyor 13.

In this case, the cutout detector 12j installed near the outlet 12c of the shooter 12 causes the book 20 to be read.
Is detected from the outlet 12c of the shooter 12, the conveyor drive motor 13a is driven, and its rotational force is transmitted to the conveyor 13 via the belt 13b. The transport conveyor 13 is installed with a predetermined upward inclination, and travels so as to transport the placed book 20 upward in the drawing. The barcode label 20b is read by the barcode reader 13e while the book 20 conveyed by the conveyor 13 is detected by the pair of book detectors 13c and 13d.

At this time, depending on the orientation when the book 20 is inserted into the book slot 11b, for example, when the book 20 is inserted with its barcode label 20b attached side down, for example. Even if the presence of the book 20 is detected by the book detectors 13c and 13d, the barcode reader 13e may not be able to read the barcode label 20b. In such a case, the conveyor 1
3 is controlled to convey the book 20 in the reverse direction, so that the book 20 is returned to the user from the book return port 11c.

On the other hand, if the barcode reader 13e can correctly read the barcode label 20b during the period in which the presence of the book 20 is detected by the pair of book detectors 13c and 13d, the read barcode is read. Is sent to the control system, the registration of the rental file for the book 20 is deleted, and the return procedure is completed here. The barcode label 20b is read in this way, and the book 20 for which the return procedure is completed
Is further conveyed by the conveyer 13 and during the period when its presence is detected by the pair of book detectors 13f and 13g, the magnetization piece 2
Magnetization to 0d is performed.

[0032] Thereafter, a library 20, which is thus conveyed to the conveyor 13, are unloaded from the unloading port 13i conveyor 13 and transferred to the sorting for pedestal 14. In this case, the transport conveyor 13 uses the book detector 13g as the book 2
When the detection of the presence of 0 is stopped, that is, when it is determined that the book 20 has been completely unloaded from the conveyor 13, the travel is stopped.

Here, the sorting pedestal 14 is mounted on a fixed frame 21 supporting the sorting mechanism 15 at an angle as shown in the drawing with respect to a horizontal plane so as to face the outlet 13i of the transport conveyor 13. Are supported by being inclined. Therefore, the leading end of the book 20 carried out from the carry-out port 13i of the carrying conveyor 13 in the carrying direction is first received by the sorting tray 14. Then, Book 20
When the book 20 is completely moved onto the sorting cradle 14 by the rear end of the book 20 being separated from the conveyor 13, the book 20 slides down along the inclination of the sorting cradle 14 by its own weight. Then, it is guided to the receiving table 16.

Here, the receiving table 16 is placed on an extension of the carry-out port 14a of the sorting table 14 so that the sorting table 1
4 is installed with substantially the same inclination as the inclination given to 4. The book 20 slid from the sorting tray 14 to the tray 16 is stopped by the stopper 22 provided at the lower end of the tray 16 in the drawing. The cradle 16
Is detected by a book detector 16a installed near the receiving table 16.

The pedestal 16 is mounted on the fixed frame 21 via a trolley 23.
7. In this case, the bottom portion 23 of the cart 23
A is provided with a positioning piece 23b. The fixed frame 21 has a position detector 21a for detecting the presence or absence of a positioning piece 23b protruding from the carriage 23 at a position corresponding to the carry-out port 14a of the sorting tray 14.
Is installed. The position detector 21a detects the presence or absence of the positioning piece 23b by, for example, optical means, and sends the detection result to the control system.

For this reason, in the control system, when the position detector 21a detects the presence of the positioning piece 23b, the carriage 23, that is, the pedestal 16 reaches the position corresponding to the carry-out port 14a of the sorting pedestal 14. Can be determined. In this case, one receiving tray 16 is used as the sorting tray 1
4 reach the positions corresponding to the carry-out ports 14a, so that the other receiving stands 16, 16,... Become the positions corresponding to the book stacking boxes 18, 18,. ,
The intervals are set.

Next, the receiving table transport mechanism 17 will be described. That is, as shown in FIG. 5, a guide rail 17a and a resin chain guide 17b formed in a substantially elliptical loop shape are arranged on the fixed frame 21 side by side. Among them, the guide rail 17a is formed by bending a rail base formed in a substantially U-shaped cross section in a loop shape so that an opening thereof faces outward.
A guide roller 23c that is loosely fitted into the opening of the guide rail 17a is provided on the bottom surface 23a of the carriage 23.

The chain guide 17b is formed by bending a rail base formed in a substantially U-shape in cross section in a loop shape with its opening facing upward. The chain guide 17b supports a loop-shaped drive chain 17c in its opening so as to be able to run in the longitudinal direction. The drive chain 17c runs in a predetermined direction by rotating a sprocket 17d meshed with a part of the drive chain 17c under the action of a motor 17e.

As shown in FIG. 6, a connecting piece 23e projects from the bottom surface 23a of the carriage 23, and the connecting piece 23e is connected to the drive chain 17c. Therefore, when the drive chain 17c travels, the carriage 23 is circulated in a loop along the guide rail 17a.

As shown in FIG. 7, the carriage 23 is formed by bending a plate in a substantially U-shape, and has two through holes 23g formed on both side surfaces 23f, 23f. The support 16 is supported by inserting a bolt (not shown). In this case, first, as shown in FIG. 4, the receiving table 16 is inclined such that the stopper 22 faces downward, and is supported by the cart 23.

Further, both side portions 23f,
23f is inclined in the same direction with respect to the bottom surface 23a as shown in FIG. For this reason, the receiving table 16 is provided with an inclination that is rotated about the transport direction of the book 20, that is, the direction in which the book 20 contacts the stopper 22.

That is, the receiving tray 16 is moved from the sorting receiving tray 14 to the stopper 22 of the receiving tray 16 in the form of the book 2.
An inclination (approximately 25 ° with respect to the horizontal direction) for causing the zero to slide down by its own weight, and an inclination (approximately 20 ° with respect to the horizontal direction) in which the book 20 is rotated about the transport direction of the book 20 as an axis. It will be. For this reason, Book 20
In the state of being transferred from the sorting cradle 14 to the cradle 16, it is biased by its own weight to one side which is substantially orthogonal to the transport direction in a plane.

Here, as shown in FIG.
The book 20 supported by the cartridge 6 is released from the lock by the stopper 22 in a state where the cart 23 is moved to a position facing the book stacking box 18 of the classification corresponding to the book 20, The book is slid down from the cradle 16 and stored in the book stacking box 18. Therefore, a mechanism for releasing the lock of the book 20 by the stopper 22 will be described below.

That is, the fixed frame 21 is set so as to be substantially horizontal on a support column 24 installed vertically to a floor surface (not shown). And this support column 2
The pushing mechanism 26 is provided at the top of the box 4 at a position corresponding to the above-mentioned ten book stacking boxes 18, 18,.

As shown in FIG. 10, the pushing mechanism 26 includes a pushing motor 26a, a pushing lever 26c having one end fitted to a rotating shaft 26b thereof, and a pushing lever 26c.
Extrusion roller 26d rotatably supported at the other end of the roller c
And a position detector 26e for detecting the position of the pushing roller 26d. Then, as shown in FIG. 9 again, the pushing mechanism 26 pushes the pushing lever 2.
The rotating surface 6 c is installed on the frame 25 so as to have the same inclination as the receiving table 16.

The position detector 26e detects that the pushing roller 26d has reached the top of the rotating surface of the pushing lever 26c. Then, the extrusion motor 26a
Is controlled so that the pushing roller 26d is always on standby at a position detected by the position detector 26e.

Here, in FIG. 9, a plate-shaped slide guide 27 is provided on the receiving table 16 as will be described later in detail.
A first sliding direction approaching the book stacking box 18 along the inclination of the receiving table 16 and a second sliding direction separating from the book stacking box 18.
It is slidably supported in the sliding direction.
However, the slide guide 27 is urged in the second sliding direction by the action of a spring (not shown). When the slide guide 27 is slid in the second slide direction, the leading end is bent into an L-shape to form an engagement piece 27a.

Then, in a state where the carriage 23 reaches between the book stacking box 18 and the pushing mechanism 26 and is stopped, the engaging piece 27a of the slide guide 27 faces the pushing roller 26d of the pushing mechanism 26. It is supposed to be. In this state, when the pushing motor 26a is driven to rotate the pushing lever 26c half a turn, the pushing roller 27d pushes the engaging piece 27a of the slide guide 27 as shown in FIG. 27 is slid in the first sliding direction against the urging force of the spring. At this time, the slide guide 27 protrudes from the receiving table 16 toward the book collecting box 18, and the receiving table 16 and the book collecting box 1
It will be a bridge between the eight.

On the other hand, the slide guide 27
The lock of the book 20 by the stopper 22 is released in conjunction with the operation of sliding the book 20 in the first sliding direction.
For this reason, the books 20 mounted on the receiving table 16 are slid down from the receiving table 16 into the book stacking box 18 via the slide guide 27 and stored.

When the books 20 are moved from the receiving table 16 to the book collecting box 18, the slide guide 27 is projected from the receiving table 16 in the direction of the book collecting box 18 in a bridge-like manner to slide down the books 20. , It is possible to prevent the occurrence of inconvenience such as the small book 20 falling between the receiving tray 16 and the book stacking box 18.

The book 20 slipped from the cradle 16 is
By sliding on the slide guide 27, the speed is limited and the book 20 is moved into the book stacking box 18, so that the book 20 is damaged as compared with the book 20 sliding down from the cradle 16 directly into the book stacking box 18. Can not be.

Further, the book 20 mounted on the receiving table 16
Due to the inclination of the pedestal 16, the pedestal 16 is biased to one side of the pedestal 16, as shown in FIG. For this reason,
When the books 20 are moved from the cradle 16 to the book stacking box 18 and sequentially stacked, the books 20 can be stacked neatly in the book stacking box 18 even if the size and paper quality of each book 20 are different. Therefore, it is possible to prevent the books 20 from collapsing in the book stacking box 18.

FIG. 12 shows details of the receiving table 16, the stopper 22, and the slide guide 27. First, the pedestal 16 is formed in a substantially rectangular plate shape, and two through holes 16c are formed in each of side surfaces 16b, 16b formed on both sides thereof. The receiving table 16 is fastened by inserting bolts (not shown) through through holes 16c formed in both side portions 16b, 16b and through holes 23g formed in both side portions 23f, 23f of the carriage 23. By doing so, the carriage 23 is supported with the two types of inclination described above.

As described above, a side guide 16d is formed on one side surface of the cradle 16 for guiding the book 20 that is biased to one side due to the inclination of the cradle 16. Further, the slide guide 27 is guided by guide portions 16e, 16e provided on both sides of the receiving table 16, respectively, so that both ends of the slide guide 27 are in the first and second sliding directions, that is, in FIG. Middle arrow A,
It is slidably supported in the direction indicated by B.

The slide guide 27 has a pair of pins 27b, 27b protruding at substantially the center of both side ends thereof, and a pair of pins protruding at the ends in the arrow B direction at both side ends of the receiving base 16. 16f, the coiled springs 27c are respectively engaged with the springs 16f so that the arrow B
Biased in the direction. Furthermore, this slide guide 2
7, a raising striker 27d and a lowering striker 27e are provided side by side.

The lower end of the stopper 22 in the figure is supported by a pair of connecting members 22a, 22a.
2b. The stopper 22 is formed such that both ends of the support shaft 22b are formed with through holes 16g, 16 formed in both side surfaces 16b, 16b of the receiving base 16.
g (one of the through holes 16g is not visible in the drawing), the book 20 is rotatably supported at a position where the book 20 is locked and a position where the book 20 is not locked.

Further, the raising cam roller 22 engaged with the raising striker 27d is mounted on the support shaft 22b.
c and the lowering cam roller 22d engaged with the lowering striker 27e are fixed to each other with an angle difference of 90 ° therebetween. As shown in FIG. 13, the lifting striker 27d has an inclined portion 27f that swells from the end of the slide guide 27 where the engagement piece 27a is formed toward the opposite end. The lower striker 27e is provided with an engagement piece 27a of the slide guide 27.
From the end opposite to the side where the
Has an inclined portion 27g that bulges toward the end where the ridge is formed.

Here, it is assumed that the stopper 22 is rotated to a position where the book 20 is locked, as shown by a solid line in FIG. At this time, the slide guide 27 is pulled in the direction of arrow B by the urging force of the spring 27c, and the lowering cam roller 22d is at a position facing the inclined portion 27g of the lowering striker 27e. In this state, when the pushing motor 26a is driven to rotate the pushing lever 26c half a turn, the pushing roller 26d presses the engaging piece 27a of the slide guide 27, so that the slide guide 27 is biased by the spring 27c. Is slid in the direction of arrow A.

At this time, with the movement of the slide guide 27, the inclined portion 27g of the lower striker 27e is moved.
Presses the lowering cam roller 22d, so that the lowering cam roller 22d is rotated counterclockwise in the drawing. For this reason, the connecting members 22a, 22a integrally connected via the lowering cam roller 22d and the support shaft 22b are also rotated in the same direction, so that the stopper 22 moves the book 20 as shown by the one-dot chain line in the figure. It is moved to a position where it does not lock.

After the stopper 22 is moved to a position where the book 20 is not locked, the slide guide 27 is projected from the receiving table 16 toward the book stacking box 18. In this manner, when the slide guide 27 is completely protruded from the receiving table 16, the slide guide 27
Lifting striker 27d is more arrow A than support shaft 22b
Side, and the inclined portion 27f is located on the cam roller 22 for raising.
c.

In such a state, the pushing motor 26
When the lever a is driven to further rotate the pushing lever 26c a half turn, the pushing roller 26d returns to the original position detected by the position detector 26e, so that the slide guide 27 is returned in the direction of arrow B by the urging force of the spring 27c.
