Description

Technical Field

[0001] This utility model relates to the field of book processing machinery technology, specifically to a book sticker feeding mechanism. Background Technology

[0002] In the bookbinding production industry, the automated and reliable feeding of bookmarks is a key factor affecting the efficiency and stability of the production line. Traditional bookmark feeding methods mostly rely on manual operation or simple pneumatic or electric push rod drives, which suffer from problems such as uncoordinated rhythm and insufficient positioning accuracy. Especially when it is necessary to separate the accumulated bookmarks one by one from the material table and guide them to the subsequent workstation, existing technologies often use multiple independently driven actuators to complete the separation, lifting, and pushing actions separately. This decentralized driving mode not only leads to complex equipment structures and large space occupation, but also makes it difficult to accurately synchronize the timing between the various actions, which can easily cause jamming, misalignment, or even tearing during the bookmark transportation process, thus restricting the overall speed and reliability of the binding production line.

[0003] To overcome the aforementioned shortcomings, some existing technologies have attempted to coordinate the actions of the unloading mechanism through mechanical linkage, such as using gear and rack mechanisms or simple rocker arm mechanisms. However, these improved solutions generally still have limitations such as short transmission chains, single functions, or inconvenient adjustments, making it difficult to achieve precise coordination and cyclical operation of multiple complex actions within a compact space. Specifically, how to efficiently drive the two functional components of book sticker traction and book sticker lifting using a single power source, enabling them to work collaboratively according to a strictly set timing trajectory, and ensuring smooth operation and ease of maintenance, remains a technical challenge that urgently needs to be optimized and solved in this field. Summary of the Invention

[0004] This utility model proposes a book sticker feeding mechanism, which solves the problem that it is difficult to achieve precise coordination and cyclic repetition of multiple complex actions in a compact space in the prior art.

[0005] The technical solution of this utility model is implemented as follows: The book label feeding mechanism includes a fixed base and a rotating shaft rotatably mounted on the fixed base; it also includes at least two sets of reciprocating transmission components, each including a cam fixed on the rotating shaft, a guide wheel rolledly connected to the outer contour of the cam, a swing arm rotatably mounted on the guide wheel and hinged to the side of the fixed base, a connecting rod hinged to the swing arm, a connecting member hinged to the connecting rod, and a swing shaft rotatably mounted on the connecting member that swings on the fixed base; The fixed base is provided with a book sticker material platform located above the rotating shaft, and the two swing shafts are respectively provided with a book sticker feeding traction component and a book sticker lifting component located at the front side of the starting end of the book sticker material platform.

[0006] Furthermore, a tension spring is connected between two adjacent swing arms to ensure that the guide wheel is always in contact with the cam.

[0007] Furthermore, the book sticker feeding and traction component consists of multiple vacuum adsorption components to adsorb the book stickers extending from the beginning of the book sticker material platform.

[0008] Furthermore, the swing axis corresponding to the vacuum adsorption component is a suction pipe, and the suction pipe is connected to the vacuum adsorption component.

[0009] Furthermore, the book sticker support is a hook-claw component, and the end of the hook-claw can support the book sticker extending from the beginning of the book sticker material platform.

[0010] Furthermore, it also includes a book sticker feeding and dispersing component, which includes a fixed base with a fixed shaft, the fixed shaft being fastened to an air blowing pipe by bolts, and the height of the air blowing pipe corresponding to the top of the book sticker material table.

[0011] The beneficial effects of the technical solution provided in this application are as follows: 1. This book label feeding mechanism features multiple sets of cam-link reciprocating transmission components driven by the same rotating shaft. This ingeniously transforms a single rotary input into coordinated actions with a specific timing between two actuators: the book label feeding traction component and the book label lifting component. This integrated mechanical linkage design fundamentally overcomes the structural redundancy, complex control, and asynchronous actions inherent in traditional multi-independent drive sources. It ensures smooth, precise, and reliable connection between the book label separation, lifting, and feeding processes, significantly improving the rhythm consistency and operational efficiency of the entire feeding process.

[0012] 2. The book label feeding mechanism utilizes a tension spring to ensure continuous and close contact between the guide wheel and the cam profile, making the transmission smoother and more reliable. The use of a vacuum suction cup as the traction component, combined with a hollow swing shaft as the suction pipe, achieves integrated and efficient execution of the adsorption function. The addition of a hook-type lifting component and an air-blowing dispersion component ensures smooth and reliable book label separation through physical lifting and airflow loosening, respectively. These components together constitute a highly efficient feeding system that is precise in action, stable in operation, and highly adaptable, effectively solving the technical challenge of achieving complex and precise coordinated movements within a compact space.

[0013] 3. The feeding mechanism described in this book utilizes the precisely plannable characteristics of the cam profile, allowing the stroke, speed, and phase difference of the traction and lifting actions to be optimized and fixed through the mechanical structure itself, resulting in stable and predictable motion patterns. This not only reduces reliance on the precision of the control system and improves the mechanism's anti-interference capability, but also makes the equipment structure compact and easy to maintain. Thus, while ensuring high-efficiency production, it enhances the long-term stability and service life of the equipment, effectively solving the technical challenge of achieving complex and precise coordinated movements within a limited space.

Detailed Implementation

[0017] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] The core design concept of this utility model's book label feeding mechanism lies in using a single power source to drive a precision cam-linkage transmission system, thereby synchronously controlling the two key actions of book label traction and lifting, and supplementing it with a book label dispersing function, to achieve an efficient, reliable and time-precise automated feeding process.

[0019] See Figures 1 to 4 The main structure of the mechanism includes a fixed base 10 that serves as the mounting foundation. This fixed base 10 provides stable support for the entire mechanism, and all moving parts are directly or indirectly mounted on it. A rotating shaft 20 is rotatably mounted on the fixed base 10 via conventional rotating pair structures such as bearings. This rotating shaft 20 serves as the power input shaft for the entire mechanism, and its rotational power is typically provided by an external motor (not shown in the figure) through belts, chains, or couplings.

[0020] The core transmission component of this invention consists of at least two sets of reciprocating transmission assemblies 60 with identical structures. Each set of reciprocating transmission assemblies 60 includes a cam 65 fixedly mounted on a rotating shaft 20. The outer contour shape of the cam 65 is pre-designed according to the desired motion law. A guide wheel 66 is rotatably mounted via a bearing and maintains rolling contact with the outer contour of the cam 65. The middle or one end of a rocker arm 61 is hinged to the side of the fixed base 10 via a pin, allowing it to swing around the hinge point. The guide wheel 66 is rotatably mounted at one end of the rocker arm 61 via an axle, thereby converting the rotational motion of the cam 65 into the reciprocating swing of the rocker arm 61.

[0021] At the end of the rocker arm 61 furthest from the guide wheel 66, a connecting rod 62 is hinged via a hinge pin. The other end of the connecting rod 62 is hinged to a connecting member 63. A swing shaft 64 is fixedly or rotatably mounted on this connecting member 63, and the swing shaft 64 itself is rotatably supported on the fixed base 10 via a bearing seat or similar structure. Therefore, when the rocker arm 61 swings, the swing shaft 64 is ultimately driven to reciprocate at a certain angle on the fixed base 10 through the transmission of the connecting rod 62 and the connecting member 63. To ensure that the guide wheel 66 closely conforms to the outer contour of the cam 65 at all times, and to avoid impact or misalignment due to gaps, a tension spring 67 is connected between the rocker arms 61 of two adjacent reciprocating transmission assemblies 60. The preload provided by the tension spring 67 causes the two rocker arms 61 to tend to move closer together, thereby ensuring continuous contact between the guide wheel 66 and the cam 65.

[0022] A book sticker material platform 40 is provided above the fixed base 10 for stacking book stickers to be unloaded. Two key actuators are arranged at the front of the beginning (i.e., the unloading port) of the book sticker material platform 40. These two actuators are respectively mounted on two swing shafts 64 driven by the two sets of reciprocating transmission assemblies 60. Specifically, a book sticker unloading traction component 30 is mounted on one swing shaft 64, and a book sticker lifting component 50 is mounted on the other swing shaft 64. When the two sets of reciprocating transmission assemblies 60 are installed, the initial contact positions of their guide wheels 66 and their respective cams 65 are symmetrical. This means that when the shaft 20 rotates, specific contour segments on the two cams 65 will act sequentially on their respective guide wheels 66, thereby driving the book sticker unloading traction component 30 and the book sticker lifting component 50 to move sequentially, forming the required timing difference, rather than complete synchronization.

[0023] In a preferred embodiment, the book sticker feeding traction component 30 can employ multiple vacuum suction components, such as vacuum suction cups. Correspondingly, the swing shaft 64 driving the vacuum suction component can be designed as a hollow suction pipe. This suction pipe 64 serves both as a transmission component to achieve the swing and as a fluid channel; its internal cavity is connected to the vacuum suction component, while its external surface is connected to a vacuum source via a rotary joint (not shown). This integrated design simplifies the piping layout and avoids the problem of hose tangling during movement.

[0024] A preferred embodiment of the book label lifting component 50 is a hook component. The end shape of the hook component is designed to extend into the bottom of the book label during operation and securely lift it. Its movement trajectory cooperates with the book label unloading traction component 30 to jointly complete the separation and transfer of the book label.

[0025] To further improve the reliability of the feeding process and prevent book stickers from failing to separate smoothly due to static electricity or adhesion, this invention also includes a book sticker feeding and dispersing component 70. This component includes a fixed shaft 71 fixedly mounted on a fixed base 10. An air blowing pipe 72 is bolted to the fixed shaft 71, and its installation height is adjusted to face the side or end of the book sticker stack on the book sticker material platform 40. The air blowing pipe 72 is connected to an air source (not shown) via a flexible hose, allowing it to blow airflow onto the book sticker stack when needed, slightly loosening the bottom few book stickers to facilitate subsequent traction and lifting actions.

[0026] The working process of this utility model is as follows: The rotating shaft 20 rotates continuously at a uniform speed, driving the two cams 65 to rotate synchronously. Since the initial contact positions of the two cams 65 and their respective guide wheels 66 are symmetrical, the cam 65 controlling the book sticker feeding traction component 30 will first enter the pushing section, driving the vacuum suction cup 30 to swing downwards and adsorb the bottom book sticker at the beginning of the book sticker material platform 40 through its transmission chain. Subsequently, the cam 65 enters the return section, causing the vacuum suction cup 30 to swing upwards and backwards while adsorbing the book sticker, completing the book sticker traction action. Almost simultaneously or slightly later, the cam 65 controlling the book sticker lifting component 50 enters the pushing section, driving the hook component 50 to swing upwards, supporting the rear end of the book sticker at the moment it is lifted or afterward, and together with the vacuum suction cup 30, supporting the book sticker to prevent it from deforming or falling off due to its own weight or speed changes. Finally, the book sticker is transferred to the subsequent conveying station. During this process, the air blowing pipe 72 can intermittently blow air to assist in the separation of the book stickers. The tension spring 67 ensures that the transmission chain is always backlash-free and operates with precision.

[0027] In summary, this specific embodiment details the structure, connection relationships, and working principle of this utility model. Through the above design, this utility model successfully transforms the complex multi-action coordination problem into a reliable mechanical motion sequence, achieving efficient, stable, and precise control of book cover feeding.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
