Detailed Description
The first embodiment is as follows: the embodiment is described with reference to fig. 1 to 19, and the library book shelving device in the embodiment includes a book poking unit 1, a book dividing unit 2, a book placing unit 3 and a book pushing unit 4, wherein the book poking unit 1 pokes books on a bookshelf through gaps, the books on two sides of the gaps are separated through the book dividing unit 2, and the book pushing unit 4 pushes the books on the book placing unit 3 to be between the books on two separated sides.
The working process of the embodiment comprises the following steps: a book to be placed on the shelf is stored in the book placing unit 3, and the book shifting unit 1 firstly shifts the book on the bookshelf to a certain gap as shown in fig. 17; then the book dividing unit 2 starts to move so that the gap between the books is large enough, as shown in fig. 18; finally, the book pushing unit 4 starts to move to push the book to be placed into the gap, as shown in fig. 19, so that the book placing operation is completed.
The book placing situation on the library bookshelf is assumed to be shown in fig. 15, and a book needs to be inserted between the books of numbers 3 and 4, generally, the book dialing action is to press the book of number 3 with one hand, mainly to prevent the book on the left side of the book of number 4 from toppling over after a gap appears, and then press the book of number 4 with the other hand, and dial the book of number 4 to the right until a sufficient gap appears.
The second embodiment is as follows: the embodiment is described with reference to fig. 1 to 19, the book-setting unit 1 of the embodiment includes a book-fixing device 1-1 and a toggle device 1-2, the book-fixing device 1-1 is fixedly connected to one side of the book-placing unit 3, a set of fixed claws 1-1-1 is arranged at the front end of the book-fixing device 1-1, a set of toggle claws 1-2-7 is arranged at the front end of the toggle device 1-2, and the toggle claws 1-2-7 are arranged opposite to the fixed claws 1-1-1. Other components and connection modes are the same as those of the first embodiment.
In the embodiment, the book dialing unit 1 is designed according to the action of dialing by a hand of a person, and the book fixer 1-1 has the function similar to that of the left hand of the person and presses the book No. 3. The dialer 1-2 functions like a person's right hand, holding book No. 4 and dialing the book to the right. Because the outermost side of a row of books is supported by the book stands, the books cannot fall outwards.
Rubber layers are wrapped on the outer sides of the poking claws 1-2-7 and the fixed claws 1-1-1 at the front end of the poking unit 1. The design separates two books by a certain gap according to the friction force generated by pressing the book spine.
The third concrete implementation mode: the embodiment is described with reference to fig. 1 to 19, the toggle actuator 1-2 of the embodiment includes a toggle motor 1-2-1, a toggle crank 1-2-2, a toggle rocker 1-2-3, a toggle slider 1-2-4, a toggle guide rod 1-2-5 and a toggle fixing frame 1-2-6, the toggle motor 1-2-1 and the toggle guide rod 1-2-5 are both fixedly connected to the toggle fixing frame 1-2-6, the toggle guide rod 1-2-5 is horizontally arranged, a motor shaft of the toggle motor 1-2-1 is fixedly connected to the middle of the toggle crank 1-2-2, one side of the toggle crank 1-2-2 is rotatably connected to one end of the toggle rocker 1-2-3, the other end of the toggle rocker 1-2-3 is rotatably connected with a toggle sliding block 1-2-4, the toggle sliding block 1-2-4 is sleeved on the toggle guide rod 1-2-5, and the toggle sliding block 1-2-4 is fixedly connected with a set of toggle claws 1-2-7 through a connecting plate 1-2-8. Other components and connection modes are the same as those of the second embodiment.
The right movement of the shifter 1-2 is realized by a slider-crank mechanism consisting of a toggle crank 1-2-2, a toggle rocker 1-2-3 and a toggle slider 1-2-4, the slider-crank mechanism is schematically shown in figure 6, which shows two extreme positions of the mechanism, wherein L1 is a gap for opening a book by a book-shifting unit, and is about 20mm according to the design.
The fourth concrete implementation mode: the embodiment is described with reference to fig. 1 to 19, the book dividing unit 2 of the embodiment comprises a second book dividing connecting rod 2-2, a fourth book dividing connecting rod 2-4, a sixth book dividing connecting rod 2-6, a book dividing screw rod 2-7, a book dividing motor 2-9, book dividing blocks 2-10, a book dividing fixing frame 2-11, a book dividing transmission mechanism, a group of first book dividing connecting rods 2-1, a group of third book dividing connecting rods 2-3 and a group of fifth book dividing connecting rods 2-5, the book dividing motor 2-9 is fixedly connected to the book dividing fixing frame 2-11, a motor shaft of the book dividing motor 2-9 is connected with the book dividing screw rod 2-7 through the book dividing transmission mechanism, the book dividing screw rod 2-7 is horizontally arranged, one end of the sixth book dividing connecting rod 2-6 is rotatably mounted on the book dividing screw rod 2-7, the other end of a sixth book dividing connecting rod 2-6 is respectively connected with one end of a group of fifth book dividing connecting rods 2-5 in a rotating mode, the other end of a group of fifth book dividing connecting rods 2-5 is respectively connected with the rear end of a fourth book dividing connecting rod 2-4 in a rotating mode, one end of a group of first book dividing connecting rods 2-1 and one end of a group of third book dividing connecting rods 2-3 are respectively connected with a book dividing fixing frame 2-11 in a rotating mode, the other end of a group of third book dividing connecting rods 2-3 is respectively connected with the front end of a fourth book dividing connecting rod 2-4 in a rotating mode, the other end of a group of first book dividing connecting rods 2-1 is respectively connected with the rear end of a second book dividing connecting rod 2-2 in a rotating mode, the rear end of the second book dividing connecting rod 2-2 is fixedly connected with the front end of the fourth book dividing connecting rod 2-4, and the front end of the second book dividing connecting rod 2-2 is fixedly connected with book dividing blocks 2-10.

The first book dividing connecting rod 2-1 and the third book dividing connecting rod 2-3 are arranged in parallel, and the first book dividing connecting rod 2-1 and the third book dividing connecting rod 2-3 are the same in length.
Although the book poking unit 1 has the function of poking a book, the book poking unit cannot poke a large gap, so that after the book poking device 1-2 pokes the book for a certain distance, a larger pressure needs to be applied to continue poking, which causes certain damage to the book, and therefore after the book poking device 1-2 pokes the dense book for a certain gap, an additional part is needed to separate the book, namely the book separating unit 2.
The gap for separating the books is far from sufficient only by forward movement of the front ends of the book splitting blocks 2-10, so that the front ends of the book splitting blocks 2-10 have forward movement and rightward book splitting movement, in order to simplify the design, only one power source is used for driving the movement in two directions, the orientation of the front end of the book splitting unit 2 is ensured to be unchanged, the movement in two directions is realized simultaneously by adopting a parallel four-bar mechanism, and the simple diagram of the parallel four-bar mechanism is shown in figure 10. F11 and F2 are resistance and friction force from books when the mechanism moves, and M is motor driving torque.
Calculation shows that if the mechanism is directly driven by the motor, the required driving torque is overlarge, so that the book dividing motor 2-9 is used for driving the book dividing screw rod 2-7, and then the parallel four-bar mechanism is driven. The mechanism diagram of the whole book-dividing unit is shown in fig. 11. The solid and dashed positions of the mechanism in the figure are the two extreme positions of the mechanism.
In the embodiment, all the book dividing connecting rods are connected through bolts.
