Description

Technical Field

[0001] The present application relates to the technical field of book printing, and in particular to an automatic book turning machine. Background Art

[0002] Books refer to books and texts bound into volumes. In a narrow sense, they are a collection of paper with text and images. The existing production process of books includes printing text, folding, stacking pages, gluing, and pasting covers. After the books are bound, they need to use three-sided cutting equipment to trim the edges of the books neatly, and then turn them over. After turning over, the two corners of the book mouth are rounded to avoid sharp corners that may scratch people's hands.

[0003] The patent with publication number: CN113968473A discloses a flipping straight-through two-in-one conveying device for plate-shaped workpieces, including a feed conveyor belt, a flipping mechanism and a discharge conveyor belt; the middle of the feed conveyor belt and the discharge conveyor belt is a flipping mechanism, and the flipping mechanism is located below the conveying surface composed of the feed conveyor belt and the discharge conveyor belt; the flipping mechanism is used to flip the plate on the feed conveyor belt 180° and place it on the discharge conveyor belt.

[0004] However, the above-mentioned flipping method can only be used for integrated objects such as sheet materials. When used for flipping books, the suction cup absorbs the cover of the book, and then during the flipping process, the paper inside the book will separate from the cover, thereby affecting the shape and posture of the flipped book.

DETAILED DESCRIPTION

[0031] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.

[0032] The present application embodiment discloses an automatic book turning machine. Figure 1An automatic book turning machine includes a workbench 1, a turning plate 2, a clamping component and a control component.

[0033] Please refer to Figure 1 The workbench 1 is used as the basic supporting structure of the entire flipping machine, and two flipping plates 2 are provided and are rotatably arranged on both sides of the workbench 1. The flipping plate 2 is circular, and a receiving groove 21 for receiving books is opened radially on the flipping plate 2. The number of the receiving grooves 21 is four and they are evenly distributed on the flipping plate 2.

[0034] For details, please refer to Figure 1 The clamping assembly is used to clamp the book in the receiving groove 21. The clamping assembly includes an electric cylinder 31 fixedly arranged on any one of the flip plates 2 and a clamping plate 32 fixedly arranged on the piston rod of the electric cylinder 31. The electric cylinder 31 realizes power transmission with an external power supply through a conductive slip ring. The clamping plate 32 is moved by the drive of the electric cylinder 31, so as to achieve a firm clamping of the book. During the flipping process, the electric cylinder 31 pushes the clamping plate 32 to press the book into the receiving groove 21, preventing the cover of the book from opening during the flipping process, and also preventing the book from shifting or falling off.

[0035] For details, please refer to Figure 1 and Figure 2 The control component includes an infrared sensor 41 fixedly arranged at the feeding end of the workbench 1, a controller 42 fixedly arranged on the workbench 1, and a driving member for controlling the rotation of the flip plate 2. The electric cylinder 31, the infrared sensor 41, the controller 42 and the driving member are electrically connected to realize the transmission of signals and the realization of control functions. When the infrared sensor 41 detects that a book enters the receiving groove 21, the infrared sensor 41 sends a signal to the controller 42. After receiving the signal, the controller 42 controls the electric cylinder 31 and the driving member to start, so that the clamping plate 32 clamps the book, and the driving member drives the rotation of the flip plate 2, thereby realizing the automatic flipping of the book.

[0036] Please refer to Figure 1 and Figure 2 A rotating shaft 11 is rotatably provided on the workbench 1, and two flip plates 2 are fixedly provided on the rotating shaft 11. In this embodiment, specifically, the driving member is a first motor 43 fixedly provided on the workbench 1, and the output end of the first motor 43 is fixedly connected to the rotating shaft 11, and the first motor 43 is electrically connected to the controller 42. The first motor 43 is started by the controller 42, and the rotating shaft 11 is driven to rotate by the first motor 43, and the flip plates 2 are driven to rotate by the rotating shaft 11, so as to realize turning over the book.

[0037] Please refer to Figure 1 and Figure 2In order to realize automatic loading and unloading, a feeding platform 5 is fixedly arranged at both ends of the workbench 1. Rollers 61 are rotatably arranged at both ends of the feeding platform 5, and a conveyor belt 62 is sleeved between the two rollers 61. Among them, the rollers 61 are provided with limit grooves matching the conveyor belt 62, so that the conveyor belt 62 is not easy to slip. At the same time, the conveyor belt 62 is against the upper surface of the feeding platform 5, so that the conveyor belt 62 slides on the upper surface of the feeding platform 5. A transmission component for driving the conveyor belt 62 to move is arranged on the feeding platform 5. Through the circular transmission of the conveyor belt 62, the books can be transferred from the previous process to the flip plate 2 for flipping, and then transferred to the next process after flipping, thereby realizing the function of automatic loading and unloading.

[0038] For details, please refer to Figure 1 , the transmission assembly includes a driving wheel 63, a pressure wheel 64 and a second motor 65. Among them, the driving wheel 63 and the pressure wheel 64 are both rotatably set on the feeding platform 5, and the conveyor belt 62 is wound around the driving wheel 63 and the pressure wheel 64. The pressure wheel 64 can increase the contact area between the driving wheel 63 and the conveyor belt 62, thereby increasing the wrap angle between the driving wheel 63 and the conveyor belt 62, so that the wrap angle between the driving wheel 63 and the conveyor belt 62 is greater than 120 degrees, thereby improving the stability of the transmission. The second motor 65 is fixedly set on the feeding platform 5, and its output end is fixedly connected to the driving wheel 63. When the second motor 65 is started, it drives the driving wheel 63 to rotate, thereby driving the conveyor belt 62 to move in a circle.

[0039] Please refer to Figure 1 and Figure 2 In order to guide the books, a slide rail 71 is fixedly provided on the feeding table 5, and two guide plates 72 are slidably provided on the slide rail 71. A passage for the books to pass through is formed between the two guide plates 72, and the passage can guide the books to move along a predetermined path, ensuring that the books can accurately enter the receiving groove 21 on the turning plate 2 for turning operation.

[0040] Please refer to Figure 1 and Figure 2 In order to fix the position of the guide plate 72 and prevent it from moving, a positioning assembly is also provided on the slide rail 71. The positioning assembly includes a slider 73 and a positioning bolt 74. The slider 73 is slidably disposed on the slide rail 71 and is fixedly connected to the guide plate 72. The positioning bolt 74 is threadedly connected to the slider 73 and can be rotated to abut against the slide rail 71. By tightening the positioning bolt 74, the slider 73 and the guide plate 72 can be firmly fixed at a specified position on the slide rail 71.

[0041] For further information, please refer to Figure 2 The distance between the two guide plates 72 is gradually reduced along the moving direction of the book, so that the book can be gradually centered, ensuring that the book is accurately positioned when entering the turning plate 2 and also ensuring the accuracy of the position when entering the next process.

[0042] The implementation principle of the embodiment of the present application is as follows: the device of the previous process conveys the book to be turned over to the conveyor belt 62, and the conveyor belt 62 conveys the book to the receiving groove 21 of the flip plate 2. When the infrared sensor 41 detects that the book has entered the receiving groove 21, it sends a signal to the controller 42. After receiving the signal, the controller 42 controls the electric cylinder 31 to start, and pushes the clamping plate 32 to tightly fix the book in the receiving groove 21. The controller 42 controls the first motor 43 to start, driving the rotation of the rotating shaft 11 and the flip plate 2, thereby realizing a 180-degree flip of the book. After the flip is completed, the controller 42 controls the electric cylinder 31 to retract, so that the clamping plate 32 releases the clamping of the book. At the same time, the turned book is conveyed out of the flipping area through the conveyor belt 62, and subsequent processing is carried out.

[0043] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
