Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a book storage management apparatus suitable for use in, for example, a large library that stores a large quantity of books, and particularly to improve the storage efficiency of the large quantity of books in a library, The present invention relates to a device for improving the efficiency of work required for taking out and returning.

[0002]

2. Description of the Related Art As is well known, recently, in a large-scale library having a large amount of books, an automatic loading / unloading system has been introduced in order to improve the efficiency of the work required to retrieve and return books. Is coming. This automatic loading / unloading system
The user takes out the book requested for lending from the library and transports it to the user counter, and at the same time, records the loan of the book, and records that the book has been returned and returns the book to the library. By automating the work of recording the accommodation position, the work required for taking out and returning the books can be executed accurately and promptly.

That is, in the automatic loading / unloading system, a bar code is attached to each book in order to facilitate management of a large amount of books stored. Also,
Each of the books is contained in a container for every plural volumes, and is stored in and out of the library in container units. Then, when it is requested to take out the book, the container accommodating the book is automatically unloaded from the library and conveyed to the user counter. The librarian takes out the desired book from the container transported to the user counter and hands it to the user, where the book is lent out.

When a book is requested to be returned,
The container that should hold the returned books is automatically delivered from the library and taken out to the user counter. The librarian puts the returned books in the container that has been taken out to the user counter, then stores the books in the original position of the library, where the books are returned.

On the other hand, in the current libraries, the fixed location rack system according to classification is adopted almost without exception as a storage management means of books. This fixed location rack system by classification is a method of storing multiple books in a library by classifying them into various fields such as "Japanese literature" and "mechanical engineering". The automatic storage system described above is combined with this fixed location rack system by category.

By the way, when the books are stored and managed by the fixed location racking system according to the classification, since the books of various sizes are mixed in one class, the maximum size of the books (for example, A4 size) It is necessary to set the height and depth of the bookshelf according to the edition. However, since about 80% of the books in the actual library are of A5 size (half of A4 size) or smaller, it is difficult to set the height and depth of the bookshelf according to the maximum size of each category. However, it causes a problem that the collection space is unnecessarily increased and a wasteful space in the library is increased to deteriorate the accommodation efficiency of the books.

Further, in the book storage management means by the fixed location rack system according to the classification, when the space of the bookshelf accommodating the books of a certain class becomes full, the excess books are accommodated in another bookshelf away from the bookshelf. In this case, the effect of classification is reduced, and in order to maintain the accommodation by classification, it is a great labor to shift the books on the bookshelf including books of other classifications as a whole. And will spend time. Therefore, in order to deal with such a situation, in the current library, the original space for storing the books belonging to each category is provided with an extra space of several 10% in advance. There is. For this reason, a problem arises that the wasted space in the library is further increased and the efficiency of storing books is deteriorated.

[0008] Further, in the case of the book storage management means by the fixed location rack system according to the classification, when the book is returned,
Since it is necessary to take out the container corresponding to the category of the book from the library to the user counter, when multiple books with different categories are returned, another container is taken out from the library to the user counter one by one. The need arises. Therefore, the number of operating times of the transport mechanism that transports the container between the library and the user counter increases,
In spite of the introduction of the automatic loading / unloading system, there is also a problem that the efficiency of the work for taking out and returning the books cannot be sufficiently improved.

Therefore, recently, a large amount of books are irrelevant to their contents, and the size (for example, A4 edition, B5 edition, A5 edition) is used.
A free location system according to size has been considered, which is classified according to only the plate or the like and the thickness does not matter) and stored. This size-based free location system is different depending on the size of the books to be accommodated, such as a container for A4 editions, a container for B5 editions, and a container for A5 and smaller editions. Different types of containers with different sizes are prepared, and each container is classified according to size and stored in a library.

In this case, the storage position of each container in the library is fixed, and the number of each container and the code of the stored book are stored in association with each other. Then, based on this stored content, the necessary container is taken out to the user counter, and when the container whose books have been taken out or returned at the user counter is returned to the library, it is stored in the container and the container. The stored contents associated with the existing books are updated.

By adopting such a storage management means for books by the size-based free location system, it is possible to reduce wasteful space in the library as much as possible and improve the efficiency of storing books. In addition, it is possible to return books of the same size in a container for storing books of that size, so it is possible to operate a transfer mechanism that transfers containers between the library and the user counter. The number of times can be inevitably reduced, and the efficiency of the work of taking out and returning the books by automation can be effectively improved.

By the way, the storage management means of the above-mentioned size-based free location method is still in the stage of development, and the efficiency of accommodating a large amount of books in the library is further improved, and at the same time, it can be taken out and retrieved. In order to improve the efficiency of the work required for return,
There is room for improvement in various respects.

[0013]

As described above, in the present book storage management means that adopts the size-based free location system, the storage efficiency of the books in the library and the removal and return work In terms of points, there is a strong demand for further improvement.

Therefore, the present invention has been made in consideration of the above circumstances, and is extremely good in that it can improve the accommodation efficiency of the books in the library, and can effectively improve the efficiency of the operation of taking out and returning the books by the automation. The purpose of the present invention is to provide an excellent book storage management device.

[0015]

A book storage management device according to the present invention includes a library having a plurality of shelf areas classified according to the size of the book, and a library housed in each shelf area of the library. A plurality of containers for accommodating a plurality of books having dimensions corresponding to the defined shelf area, the accommodation positions of the plurality of containers in the library, and the respective book codes of the plurality of books accommodated in the respective containers. By inputting the storage means for storing and the book code of the book requested to be taken out, the container accommodating the requested book is taken out from the library based on the stored contents of the storage means, conveyed to the station, and returned. By inputting the dimension information of the requested book, the empty container is taken out of the library from the plurality of containers corresponding to the dimension of the returned book. And conveying means for conveying to the station,
It is equipped with an updating means for updating the storage contents of the storage means for the container from which the requested book has been taken out or the return book has been returned to the station by this transfer means, and to be transferred to a plurality of shelf areas of the library. A plurality of containers are accommodated in the depth direction with respect to the front side for taking out the container by the means, and the transfer means is provided with transfer means for taking out the front side container and then the back side container with respect to the front side for taking out the container. I am trying.

[0016]

According to the above structure, a plurality of containers are accommodated in the depth direction with respect to the frontage for loading and unloading the containers in the shelf area. Therefore, the conventional storage management means by size is used. In comparison with the above, the storage efficiency of the books in the library can be further improved. Further, by preferentially using the management method of using the container on the front side, it is possible to effectively improve the efficiency of the work of taking out and returning the book.

The operation of the automatic loading / unloading system having the above-mentioned structure will be described below. Figure 15
3 is a flowchart for explaining a returning operation of the book 30. The returning operation of the book 30 is started by handing the book 30 returned by the user to the librarian of the station 20 on the first floor (step S1). First, in step S2, the librarian at the first floor station 20 operates the console 54 to input an instruction to store the return book 30 into the central processing unit 39. In this case, the librarian also operates the console 54 to input the size of the book 30 to be returned (A4 version, B5 version or A5 version or smaller) into the central processing unit 39.
