Description

Device suitable for books letter sorting

Technical Field

The invention relates to the field of library related technical equipment, in particular to a device suitable for book sorting.

Background

After the book is returned to the library by the reader, the book is temporarily stored in the book returning place. The book return department can regularly sort the books to be returned for the second time, and then arrange the books on the large bookshelf of the library according to the classification number for the readers to borrow the books again.

The existing secondary book sorting device is provided with a book storage box with an open top, universal wheels are arranged at the bottom of the book storage box, and handrails are arranged on the side parts of the book storage box. When in use, the books to be returned are sequentially arranged in the book storage box from bottom to top. From the viewpoint of improving the work efficiency, the librarian can arrange the books to be returned in the book storage box in an aligned or layered manner based on the classification number. The books to be returned can not form a whole column or a whole layer under normal conditions, so that the books to be returned can only be mixed with books of other classification numbers in the same box body, and a lot of inconvenience is caused.

Meanwhile, because the existing book storage box is of a single box type structure, a librarian needs to bend down to take books for many times in the process of returning the books. Because books are sorted by a large amount, the work intensity of a librarian is high, and lumbar muscles are easy to strain. And because the book resources comprise audio-visual data and books and periodicals, and the quality of the books and periodicals is much higher than that of the audio-visual data under the condition of the same volume, the secondary book sorting device is often used under the condition of loading too many books and periodicals, so that the universal wheels are damaged prematurely.

As the improvement, novel books secondary sorting device generally includes two small-size bookshelf of installing on same base, and the base bottom has the universal wheel. The secondary sorting device of this structure can both sides deposit books to the books of different classification numbers are arranged, and are comparatively convenient. However, the sorting device with the structure also has some disadvantages, including:

(1) the sorting device has only two rows of small bookshelves in the transverse direction, so that the transverse width of the sorting device is only about 50 cm. But the height is more than about 135 cm, so that the height-width ratio is large and side turning is easy to happen. And because the single carrying capacity of the small bookshelf is small, a librarian needs to go back and forth between the large bookshelf and a book return position for many times.

(2) Sorting device can't carry out both sides to books and fix, often has books to drop from small-size bookshelf.

(3) The sorting device can not classify and fix the books in the same row of the bookshelf, so that the books of different sub-items of the same classification number are difficult to distinguish, and the workload is increased.

(4) The sorting device can not carry out inboard fixing to books, and then when books of same classification number can't normally fill up the bookshelf, books often slip (books askew stand on the bookshelf).

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings.

Example (b): an apparatus for book sorting, the overall structure of which is shown in fig. 1, fig. 2, fig. 3 and fig. 4, comprising:

a main frame 20 having an open structure at the top and left and right sides;

the main frame 20 has a bottom plate 22, a front support plate 21 and a rear support plate 23;

universal wheels 40 are arranged on the bottom plate 22;

the front rotary disc 61 is mounted on the front support plate 21, and the front rotary disc 61 is in running fit with the front support plate 21;

a rear turntable 62 is arranged on the rear supporting plate 23, and the rear turntable 62 is in running fit with the rear supporting plate 23;

the front turntable 61 is positioned between the front support plate 21 and the rear support plate 23, and the rear turntable 62 is also positioned between the front support plate 21 and the rear support plate 23.

On the front rotary table 61, there are a plurality of positioning holes 611 and a plurality of front axle holes 612, the positioning holes 611 and the front axle holes 612 are arranged at intervals, and there are insertion holes 211 on the front support plate 21; a pin 10 penetrates through the insertion hole 211 and the positioning hole 611, and can limit the rotation of the front rotary plate 61.

Meanwhile, a plurality of rear shaft holes 622 are provided on the rear turntable 62.

A plurality of bookshelves 30 are provided in a space between the front turntable 61 and the rear turntable 62. Each bookshelf 30 is a structure with an open top and no open sides. The front end of the bookshelf 30 is provided with a front supporting shaft 31, and the rear end of the bookshelf 30 is provided with a rear supporting shaft 35; the front support shaft 31 is inserted into the front shaft hole 612 to form a rotating fit with the front turntable 61, and the rear support shaft 35 is inserted into the rear shaft hole 622 to form a rotating fit with the rear turntable 62. As a more preferable structure, bearings may be installed in both the front shaft hole 612 and the rear shaft hole 622, and the front support shaft 31 and the rear support shaft 35 are inserted into the inner rings of the bearings, so that the rotation is more smooth.

In any bookshelf 30, the distance L from the axis of the front support shaft 31 to the top of the bookshelf 30₁₁The distance from the axis of the front support shaft 31 to the bottom of the bookshelf 30 is L₁₂And L is₁₁Less than L₁₂. Meanwhile, the distance from the axis of the rear supporting shaft 35 to the top of the bookshelf 30 is L₂₁The distance from the axis of the rear supporting shaft 35 to the bottom of the bookshelf 30 is L₂₂And L is₂₁Less than L₂₂And the axes of the front support shaft 31 and the rear support shaft 35 on the same bookshelf 30 coincide. The structure can make most of the bookshelf 30 below the axes of the front support shaft 31 and the rear support shaft 35, so that the bookshelf 30 can realize self-centering function under the action of gravity (namely, no matter the front turntable 61 and the rear turntable 35 are used for supporting books or not used for loading books)How the rear turntable 62 rotates and the bottom surface of the bookshelf 30 is always parallel to the ground), preventing the bookshelf 30 from turning over due to too many books loaded.

Since the bookshelf 30 has a structure with an open top and no openings at both sides, the books do not fall off from both sides of the bookshelf 30 after being loaded on the bookshelf 30.

As a preferred structure, L₁₁And L₁₂The ratio of the two can be 1:4, L₂₁And L₂₂The ratio is also 1: 4. In this way, it is sufficient to ensure that the center of gravity of the bookshelf 30 is always below the axis.

Referring to fig. 5, 6 and 7, on both side surfaces of the bookshelf 30, there are provided clamping grooves 33. Two sides of the bookshelf 30 are respectively fixedly connected with a clamping plate 32, and each clamping plate 32 is provided with a strip-shaped hole 38; at least one blocking rod 34 is positioned in the clamping groove 33, two ends of the blocking rod 34 are protruded out of the bookshelf 30, two ends of the blocking rod 34 are fixedly connected with the top end of a tension spring 36 respectively, and the bottom end of the tension spring 36 is fixedly connected with a clamping block 37 positioned below the clamping plate 32; the tension spring 36 penetrates through the strip-shaped hole 38. Under the action of the tension spring 36, the stop lever 34 is always pulled downwards and is clamped in the clamping groove 33 without moving. According to the needs, the librarian can move the stop lever 34 upwards, then the card is fixed in the appropriate slot 33, and depending on the separation effect of the stop lever 34, the librarian can fix the books with the same classification number but unable to fill the bookshelf 30 in the same bookshelf 30, and also can load the books with different classification numbers in the same bookshelf 30 for distinguishing, and can also prevent the books from slipping, which is very convenient.

The number of the bookshelves 30 may be 4 to 6, preferably 5. Therefore, the device can ensure that the overall quality is not too high, the books loaded are not too few, and the number of times that a librarian goes to and from a book borrowing room and returns the books is too large. However, the structure of all the bookshelves 30 should be the same no matter how many bookshelves 30 are. The size of the bookshelf 30 can be selected as appropriate. For example, when the width of the bookshelf 30 is 30 cm, the entire width of the device can be more than 1 m in the state shown in fig. 1, and sufficient stability can be ensured.

The present invention also creates an innovation in the construction of the caster 40 in order to prevent premature failure of the caster 40. Referring to fig. 8, the universal wheel 40 mainly includes an L-shaped supporting frame 41, an inner side of the L-shaped supporting frame 41 is fixedly connected to a carrier 42, a rotating shaft 43 vertically penetrates through the carrier 42, and a bottom of the rotating shaft 43 is fixedly connected to a universal wheel carrier 45; the rotating shaft 43 is sleeved with a compression spring 44, and the compression spring 44 is positioned between the carrier 42 and the universal wheel carrier 45. This structure enables the compression spring 44 to be compressed, that is: when a proper amount of books are loaded, the pressure spring 44 is compressed moderately, the distance between the side part of the L-shaped support frame 41 and the ground is reduced but is not zero, the L-shaped support frame 41 is not in contact with the ground, and the universal wheels can roll normally. When too many books are loaded, the compression spring 44 is compressed excessively, the distance between the side of the L-shaped support 41 and the ground is zero, and the L-shaped support 41 directly contacts with the ground. At this moment, in the moving process, the device can generate harsh noise to prompt a librarian that the books are loaded too much. And because the L-shaped support frame 41 forms rolling friction of a sliding friction non-universal wheel after being directly contacted with the ground, the device can be very labored to move, and can also play a role in prompting a librarian that books are loaded too much.

Therefore, the universal wheel can not be damaged too early due to overload in the using process of the device.

For convenience of use, the present invention further has an armrest 50 mounted on the rear support plate 23.

When in use, the book to be returned is loaded into the bookshelf 30 and then fixed or separated by the stop lever 34 as appropriate. After pushing the device to a corresponding large bookshelf, a librarian takes out the books in the bookshelf at the top without bending down and directly puts the books into the large bookshelf. Subsequently, the device is pushed to the next large bookshelf, the bolt 10 is pulled out, the front rotary disc 61 is manually rotated to rotate the next bookshelf 30 to the position of the previous bookshelf, and then the bolt 10 is inserted into the positioning hole 611 to realize the locking of the front rotary disc, which can be seen in fig. 4. Because each bookshelf 30 has a self-centering function, when the front turnplate 61 and the rear turnplate 62 revolve clockwise, the bookshelf 30 can automatically rotate counterclockwise at an equal angular speed, and the bookshelf 30 is ensured to be in a horizontal state all the time. At this time, the height of the bookshelf 30 originally located below is raised, so that a librarian can directly take books from the rotated bookshelf 30 without bending down and return the books, and the bookshelf is very convenient. Because there is the locking effect of bolt 10, so at the in-process of returning the book, even left 3 bookshelf 30 all fills up books, 3 bookshelf 30 on right side all have been returned the book and have been accomplished (vacant), left 3 bookshelf 30 can not carry out the anticlockwise rotation because of the effect of gravity yet, and then has guaranteed to wait to return the bookshelf 30 of book and be in the highest position all the time for the librarian no matter return the books of which bookshelf 30, all need not to bend over and get the book.
