Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Figure 1 is a structural schematic diagram of a book turning device according to an embodiment of the utility model, Figure 2 FIG. 1 is a partially enlarged schematic diagram of a book turning device according to an embodiment of the utility model; Figure 1-2 As shown, the device includes: an upper fixed plate 1, a synchronous belt 2, a left frame 3, a right frame 4, a ball screw 5, a screw nut 6, a lifting motor 7, a book clamping assembly 8, a cylinder 9, and a rotating motor 10.

[0021] Among them, the synchronous belt 2 is arranged on the upper fixed plate 1; the left frame 3 and the right frame 4 are fixedly connected to the two ends of the upper fixed plate 1 respectively; the ball screw 5 includes two, one end of the two ball screws 5 is respectively connected to one end of the synchronous belt 2, and the other end is respectively fixed to the left frame and the right frame 5 through a fixed block; the screw nut 6 includes two, and the screw nut 6 is used in conjunction with the ball screw 5; the lifting motor 7 is arranged on the upper fixed plate 1, and the lifting motor 7 is used to drive the synchronous belt 2 to rotate, thereby driving the ball screw 5 to rotate so that the screw nut 6 moves up and down on the screw; the book clamping assembly 8 includes an upper belt 81 and a lower belt 82, and the two ends of the book clamping assembly 8 are respectively connected to the screw nut 6, and the screw nut 6 drives the book clamping assembly 8 to move up and down on the ball screw 5; the cylinder 9 is arranged on both sides of the upper belt 81, and is used to control the descent of the upper belt 81, so that the upper belt 81 and the lower belt 82 are clamped; the rotating motor 10 is connected to the book clamping assembly 8, and the rotating motor 10 is used to drive the book clamping assembly 8 to flip.

[0022] Specifically, Figure 1As shown, the device mainly realizes the transfer of books from the high conveyor belt of the previous station to the roller conveyor line of the next station, and the flipping of the books placed upside down. The ball screws 5 arranged on both sides are responsible for moving the book clamping assembly 8 up and down to realize the high and low position transfer and flipping of the books. If the book is facing the right direction, the lifting motor 7 drives the ball screws 5 on both sides to lower the book clamping assembly 8 to the flush position with the next station. If it is determined that the book is facing the wrong direction, the upper belt 81 is controlled to descend by the control cylinder 9 so that the book clamping assembly 8 is clamped, and then the lifting motor 7 drives the book clamping assembly 8 to descend to the middle position. After the movement reaches the middle position, the movement stops, and the rotating motor 10 controls the book clamping assembly 8 to rotate 180, and then descends to the flush position with the next station. Therefore, the utility model can flip the book over when the book is facing the wrong direction, which is convenient for accurate information collection or marking operations when the books are put into storage, avoiding errors in subsequent storage, and saving manpower.

[0023] In one embodiment of the present invention, Figure 2 As shown, the above-mentioned book turning device also includes: a slider 11, a slider fixing plate 12 and a square bearing seat 13, the slider 11 is fixedly connected to the screw nut 6; the slider fixing plate 12 is fixed to the left frame 3 or the right frame 4 through a slide rail 14; one end of the square bearing seat 13 is fixedly connected to the slider 11 through the slider fixing plate 12, and the other end of the square bearing seat 13 is fixedly connected to the book clamping assembly 8.

[0024] In one embodiment of the present invention, the rotary motor 10 is fixed on a slider fixing plate 12 .

[0025] In one embodiment of the present invention, Figure 2 As shown, the book turning device may further include: a beam sensor 15 , which is arranged on the upper belt and the lower belt, and is used to detect whether there is a book on the book clamping assembly 8 .

[0026] Specifically, the arrow of the book clamping component 8 indicates the direction of the book's movement. After the book enters, it will block the shooting sensor 15, and the receiving end cannot receive the transmission signal. After the book enters, the belt continues to transport until the shooting sensor 15 is no longer blocked, the book is controlled to stop, and the book enters the book clamping component 8.

[0027] In one embodiment of the utility model, the book turning device may further include: an in-position sensor 16, a programmable logic controller PLC and an image recognizer. The in-position sensor 16 includes the first to third sensors, which are respectively arranged at the upper, middle and lower parts of the lifting direction of the ball screw 5 to detect the position of the book clamping assembly. The programmable logic controller is respectively connected to the beam sensor 15 and the in-position sensor 16, and controls the lifting motor 7, the cylinder 9 and the rotating motor 10 according to the data detected by the beam sensor 15 and the position sensor 16. The image recognizer is connected to the programmable logic controller, and the image recognizer is used to identify the direction of the book and send it to the programmable logic controller.

[0028] Specifically, after the book enters, it will block the beam sensor 15, and the receiving end will not receive the transmission signal. After the book enters, the belt continues to transmit until the beam sensor 15 is no longer blocked, and the book is controlled to stop, and the book enters the book clamping assembly 8. The image recognizer identifies the direction of the book and sends the recognition result to the PLC. If the direction is placed correctly, the PLC controls the lifting motor 7 to drive the ball screws 5 on both sides to lower the book clamping assembly 8 to the same position as the next station. If it is determined that the book is facing the wrong direction, the PLC controls the upper belt 81 to descend by controlling the cylinder 9 so that the book clamping assembly 8 is clamped, and then the PLC controls the lifting motor 7 to drive the book clamping assembly 8 to descend to the middle position according to the position information detected by the in-place sensor 16. When the movement reaches the middle position, the movement stops, and the rotating motor book clamping assembly 8 rotates 180°, and then descends to the same position as the next station. In this way, it can be ensured that the book entering the next process is facing the correct direction.

[0029] In summary, according to the book turning device of the utility model, through the cooperation of the motor, the book clamping assembly and the cylinder, the book can be turned over when the book is facing the wrong direction, which is convenient for accurate information collection or marking operations when the book is put into storage, avoiding errors in subsequent storage, and saving manpower.
