Technical Field

[0001] This invention relates to the field of printing technology, and in particular to a handover mechanism and an automated printing device. Background Technology

[0002] Automated printing equipment typically features an automatic conveyor system to move printed materials, automatically transporting them to various printing stations. Printed materials include certificates, cards, and brochures. Due to the diverse content, printing components used include laser printing and inkjet printing, requiring multiple modules to perform the corresponding printing operations. Handing over printed materials between adjacent modules involves unloading and reloading, resulting in a cumbersome structure and a high risk of loading or unloading errors that could lead to machine downtime. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a handover mechanism that can realize the handover of printed materials between adjacent automated modules, with high efficiency and good stability.

[0004] The present invention also proposes an automated printing device having the above-mentioned handover mechanism.

[0005] According to a first aspect of the present invention, the handover mechanism includes a first module, a second module, a storage component, and a pushing component. The first module is provided with a first conveying component to convey printed materials. The second module is arranged adjacent to the first module and is provided with a second conveying component to convey the printed materials. The storage component is connected to the first module and includes a frame, a buffer rack, and a first driving component. The frame is provided with a vertical guide rail, and the buffer rack is slidably connected to the guide rail. The first driving component can drive the buffer rack to move. The buffer rack is provided with at least one storage space to accommodate printed materials. The pushing component is connected to the first module and includes a base, a first push plate, a second push plate, a second driving component, and a third driving component. The base is provided with a horizontal first slide rail and a second slide rail. The first push plate is slidably connected to the first slide rail, and the second push plate is slidably connected to the second slide rail. The second driving component can push the first push plate to move so as to push the printed materials from the first conveying component into the storage space. The third driving component can push the second push plate to move so as to push the printed materials out of the storage space and hand them over to the second conveying component.

[0007] The storage component's buffer rack has at least one storage space to hold printed materials. A first conveying component of the first module moves the printed materials close to the buffer rack. A first pusher plate of the pushing component pushes the printed materials into the storage space of the buffer rack. Then, a first driving component drives the buffer rack to rise, aligning the storage space with the height of the second pusher plate. The second pusher plate of the pushing component pushes the printed materials out of the storage space and connects them to the second conveying component of the second module. The first and second pusher plates of the pushing component enable the storage and output of printed materials in the storage component, facilitating the transfer and handover between the first and second modules. This method is highly efficient, stable, and meets the requirements of automated printing equipment.

The structure of the second conveying assembly is the same as that of the first conveying assembly.

[0010] According to some embodiments of the first aspect of the present invention, a push block is connected to the end of the first push plate, the push block being connected to the first push plate via a horizontal pivot. When the first push plate moves toward the buffer rack, the push block remains in a vertical position to push the printed material; when the first push plate moves away from the buffer rack, the push block can rotate to avoid contact with the printed material.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0034] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0035] Understandably, referring to Figures 1 to 7 An embodiment of the first aspect of the present invention provides a handover mechanism applied to an automated printing device, which enables the handover of printed materials between adjacent automated modules with high efficiency and good stability. It is understood that the printed materials include certificates, cards, brochures, etc., and the following description will use "certificate" as the reference.

[0036] The handover mechanism includes a storage component 100, a pushing component 200, a first module 300, and a second module 400. The first module 300 is equipped with a first conveying component 310 for conveying certificates, and the second module 400 is equipped with a second conveying component 410 for conveying certificates. The functions of the first module 300 and the second module 400 can be one or a combination of loading, unloading, laser printing, inkjet printing, etc. The handover mechanism proposed in this invention can realize the transmission and handover of certificates between any two modules, meeting the needs of automated production.

[0037] The storage assembly 100 consists of a rack 110, a cache rack 120, and a first drive component 130. The rack 110 is the supporting structure of the entire storage mechanism and is mounted on the first module 300. Vertical guide rails 111 are provided on the rack 110. The cache rack 120 is designed to slide along the guide rails 111, enabling vertical movement of the cache rack 120. Typically, two guide rails 111 are used and spaced apart to provide more stable support for the cache rack 120. Considering the large size of the cache rack 120, two sliders 112 are connected to each guide rail 111, and the two sliders 112 are distributed at the upper and lower ends of the cache rack 120, making the movement of the cache rack 120 smoother and the support more reliable. At least one storage space 121 is provided on the cache rack 120, which is designed to accommodate certificates. The first drive component 130 drives the cache rack 120 to move up and down along the guide rails 111 to adjust the height of the storage space 121. The first drive component 130 can be powered by a motor, hydraulic or pneumatic power source, depending on the design requirements of the transfer mechanism and the operating environment.

[0038] The pushing component 200 includes a base 210, a first push plate 220, a second drive component 230, a second push plate 240, and a third drive component 250. The base 210 is connected to the first module 300, providing a fixed foundation for the pushing component 200. The base 210 is provided with a horizontal first slide rail 211 and a second slide rail 212. The first push plate 220 slides along the first slide rail 211. The function of the second drive component 230 is to push the first push plate 220 along the first slide rail 211 to push the certificate into the storage space 121. The second push plate 240 is designed to eject the certificate from the storage space 121. The second push plate 240 is slidably connected to the second slide rail 212 on the base 210. The second slide rail 212 is also horizontally arranged and parallel to the first slide rail 211. The third drive component 250 is responsible for pushing the second push plate 240 along the second slide rail 212 to achieve the action of the second push plate 240 ejecting the certificate.

[0039] If the cache rack 120 uses a storage space 121, the first push plate 220 pushes the certificate into the storage space 121, the first drive component 130 drives the cache rack 120 to rise, and then the second push plate 240 pushes the certificate out of the storage space 121 and hands it over to the second transport component 410 of the second module 400.

[0040] If the buffer rack 120 uses multiple storage spaces 121, the first pusher plate 220 pushes the certificate to be precisely placed in the storage space 121 in the horizontal direction. The first drive component 130 and the second drive component 230 work together to raise the buffer rack 120 by one level, so that the next certificate can be pushed into the corresponding storage space 121. At the same time, the storage space 121 containing the certificate corresponds in height to the second pusher plate 240. The second pusher plate 240 pushes the certificate out of the storage space 121 and hands it over to the second conveying component 410 of the second module 400. The process is carried out in an orderly manner without interference.

[0041] It is understandable that, for the lifting and moving of the cache rack 120, the second push plate 240 can be positioned above the first push plate 220, with the height difference between the second and first push plates 220 matching the height change of the storage space 121. Alternatively, the second push plate 240 can be positioned below the first push plate 220, or the second push plate 240 and the first push plate 220 can be set to the same height.

[0042] Furthermore, to monitor the status of the certificates in real time, sensors are connected to the cache rack 120. These sensors are distributed on the side walls of the storage space and can detect the certificates in each storage space. Various types of sensors can be used, such as infrared sensors, weight sensors, or RFID sensors, depending on the material of the certificate and the parameters to be monitored. The main function of the sensors is to detect whether the certificate has been stored in the storage space 121.

[0043] In addition, the sensor can be linked with other parts of the handover mechanism (such as the first drive component 130, the second drive component 230 and the third drive component 250) to quickly realize the handover of certificates according to the storage status of the certificates.

[0044] The first push plate 220 and the second push plate 240 of the push component 200 realize the storage and output of the certificate in the storage component 100, and realize the transmission and handover between the first module 300 and the second module 400. It is efficient, stable and meets the needs of automated printing equipment.

[0045] Furthermore, along the moving direction of the second push plate 240, the length of the second push plate 240 is greater than the length of the first push plate 220, and the difference in length between the second push plate 240 and the first push plate 220 is greater than the length of the storage space 121, ensuring that the second push plate 240 can penetrate the entire storage space 121 when pushing out the certificate, thereby effectively pushing the certificate completely out of the storage space 121.

[0046] In practical applications, when it is necessary to retrieve the certificate stored in storage space 121, the third drive component 250 is activated, pushing the second push plate 240 to move along the second slide rail 212. The front end of the second push plate 240 contacts the certificate and applies a pushing force to push the certificate out of storage space 121. The second push plate 240 can be provided with two spaced-apart pushing surfaces, making the movement of the certificate more stable and the force more even.

[0047] In the handover mechanism proposed in this invention, in order to achieve an efficient and automated certificate processing flow, each module works collaboratively through its own controller. The first module 300 has a first controller, and the second module has a second controller. The two controllers are connected by communication and can exchange data and instructions to ensure that the certificate is successfully handed over between the two modules.

[0048] The first conveying assembly 310 includes a first conveyor belt 311, which is provided with multiple sets of positioning blocks 312. Each set of positioning blocks 312 defines a slot to accommodate the certificate. The second conveying assembly 410 includes a second conveyor belt 411, which has the same structure as the first conveyor belt. When the first pusher plate 220 pushes the certificate off the first conveyor belt 311, considering that the positioning blocks 312 may obstruct the certificate, the first controller controls the first conveying assembly 310 and the pusher assembly 200 to move together. The first conveyor belt 311 moves forward, causing the positioning blocks 312 to move to a position that does not obstruct the certificate (for example, by using guide wheels to turn the first conveyor belt 311 so that the position of the positioning blocks 312 is lower than the certificate). The front end of the certificate moves on the tray of the first module 300, and then the first pusher plate 220 pushes the certificate into the storage space 121. During the handover, the first controller and the second controller communicate to control the second conveying component 410 and the pushing component 200 to work together. Similarly, in order to prevent the positioning block on the second conveyor belt 411 from blocking the certificate, the second conveyor belt 411 moves backward, so that the positioning block moves to a position that does not block the certificate (for example, by using guide wheels to turn the second conveyor belt 411 so that the position of the positioning block is lower than the certificate). At this time, the second push plate 240 pushes the certificate out of the storage space 121. The certificate falls on the second conveyor belt 411, and the second conveyor belt 411 moves forward synchronously, so that the certificate accurately enters the slot of the second conveyor belt 411.

[0049] In practical use, the cache rack 120 of the storage component 100 has multiple storage spaces 121 to accommodate certificates, allowing for the temporary storage of multiple certificates. For example, when the second module 400 malfunctions or stops, the cache rack 120 can be used to temporarily store certificates. After the second module 400 resumes normal operation, it can output certificates for continuous automated production, reducing downtime and improving production efficiency. The handover mechanism proposed in this invention is an automated and efficient certificate storage solution, making certificate management more convenient and orderly.

[0050] In some embodiments of the present invention, in order to ensure stable storage and convenient access to the certificates, the structure of the cache rack 120 has been optimized. The specific structure is as follows: The cache rack 120 adopts a frame structure to form a multi-layer storage space 121, which not only improves the overall structural strength and rigidity of the cache rack 120, but also increases the space utilization rate of the cache rack 120. Each storage space 121 is provided with an upper positioning block 122 and a lower positioning block 123. A gap matching the thickness of the certificate is formed between the upper positioning block 122 and the lower positioning block 123. After the certificate enters, it can be accurately positioned, eliminating the slippage or displacement of the certificate. In order to facilitate the entry of the certificate, both the upper positioning block 122 and the lower positioning block 123 are designed with chamfers on the entrance side of the storage space 121. By setting the chamfers, the entrance is enlarged, preventing the certificate from colliding with the upper positioning block 122 and the lower positioning block 123. Moreover, the chamfers can push the certificate to automatically enter between the upper positioning block 122 and the lower positioning block 123, and also make the movement of the certificate smoother.

[0051] In some embodiments of the present invention, the first driving component 130 includes a first motor 131, a lead screw 132, and a nut 133. The first motor 131 serves as a power source, and its output shaft is connected to the lead screw 132. The lead screw 132 is arranged vertically and parallel to the guide rail 111. The nut 133 is fitted onto the lead screw 132 and connected to the buffer frame 120 via a support plate. When the motor operates, the rotation of the lead screw 132 drives the nut 133 to move axially along the lead screw 132, thereby driving the buffer frame 120 to rise and fall along the guide rail 111. The frame 110 has a vertical plate, with the lead screw 132 and the guide rail 111 positioned on opposite sides of the vertical plate. A vertical groove is provided on the frame 110 (vertical plate), through which the support plate passes, resulting in a more compact structure.

[0052] During operation, by controlling the rotation of the first motor 131, the lifting position of the cache rack 120 can be precisely controlled, thereby enabling rapid access to storage spaces 121 at different heights. This not only improves the efficiency of storing and retrieving certificates but also ensures the accuracy and reliability of the operation.

[0053] Understandably, considering the continuous transport of certificates, the first pusher plate 220 will collide with the certificates during its retraction. Therefore, an improved design was implemented for the first pusher plate 220: a pusher block 221 is connected to the end of the first pusher plate 220. The pusher block 221 is connected to the first pusher plate 220 via a horizontal rotating shaft 222. When the first pusher plate 220 moves towards the buffer rack 120, the pusher block 221 remains vertical and contacts the certificates, smoothly pushing them into the storage space 121. When the first pusher plate 220 moves away from the buffer rack 120, the pusher block 221 contacts the certificates. The pusher block 221 can rotate around the rotating shaft 222 to avoid the certificates, preventing them from being displaced by the pusher block 221. In addition, the first push plate 220 can also have a lifting function. After the certificate is pushed into the storage space 121, the first push plate 220 rises a certain distance to avoid the certificate. The first push plate 220 can be driven to rise and fall by a structure such as a cylinder or cam.

[0054] Furthermore, to keep the pusher block 221 vertical and improve the stability of pushing the certificate, the first pusher plate 220 is connected to an elastic element. The function of this elastic element is to keep the pusher block 221 in a vertical position. When the first pusher plate 220 moves towards the buffer rack 120, the elastic element provides a continuous force to ensure that the pusher block 221 always remains vertical. When the first pusher plate 220 moves away from the buffer rack 120, the pusher block 221 automatically flips to avoid the certificate and returns to its initial pushing position. The elastic element then drives the pusher block 221 to return to a vertical position. The elastic element can be a spring, elastic rubber, or a sheet spring, etc. For example, a torsion spring can be used as the elastic element. The torsion spring is fitted onto the rotating shaft 222, and its two ends are connected to the first pusher plate 220 and the pusher block 221, respectively.

[0055] In practical use, when the certificate needs to be pushed into the storage space 121, the second drive component 230 pushes the first push plate 220 towards the cache rack 120. The push block 221 remains vertical under the action of the elastic element, ensuring contact with the certificate. After the push is completed, the second drive component 230 pulls the first push plate 220 back. At this time, the push block 221 contacts the certificate and automatically rotates around the pivot 222 to avoid the certificate. Moreover, the structure of the first push plate 220 provides limiting and support for the push block 221. For example, the first push plate 220 abuts against the side of the push block 221. When the push block 221 pushes the certificate, it cannot rotate around the pivot 222, providing sufficient thrust and improving reliability.

[0056] In some embodiments of the present invention, the second drive component 230 includes a second motor 231, a drive pulley 232, a driven pulley 233, and a synchronous belt 234. The second motor 231 is a power source, fixed to the base 210 and located at one end of the first slide rail 211. The driven pulley 233 is rotatably connected to the base 210 and located at the other end of the first slide rail 211. The output shaft of the second motor 231 is fixedly mounted with the drive pulley 232. The drive pulley 232 and the driven pulley 233 are connected by the synchronous belt 234 to form a transmission system, ensuring the tension and stable operation of the synchronous belt 234. The synchronous belt 234 is a flexible transmission element capable of moving and transmitting power between the drive pulley 232 and the driven pulley 233.

[0057] The first push plate 220 is fixedly connected to the timing belt 234 via the first support arm 223. The second motor 231 starts, driving the drive wheel 232 to rotate, which in turn drives the first push plate 220 to move linearly along the first slide rail 211 via the timing belt 234. This allows the first push plate 220 to accurately push the certificate to the predetermined storage space 121.

[0058] In practical applications, the second drive component 230 controls the movement of the first pusher plate 220 by controlling the start, stop, and rotation speed of the second motor 231, thereby achieving precise pushing of the certificate. For example, when the certificate needs to be stored in the storage space 121, the second motor 231 starts, driving the first pusher plate 220 to move along the first slide rail 211 towards the cache rack 120, and the pusher block 221 pushes the certificate into the storage space 121. After the pushing is completed, the second motor 231 reverses, and the first pusher plate 220 returns to its original position, ready for the next pushing.

[0059] It is understandable that the structure of the third drive component 250 is similar to that of the second drive component 230, both being driven by a motor and a synchronous belt, thereby driving the second push plate 240. Alternatively, the third drive component 250 may use an electric actuator to directly drive the second push plate 240.

[0060] In some embodiments of the present invention, the base 210 is designed to include a first mounting plate 213 and a second mounting plate 214, the first mounting plate 213 and the second mounting plate 214 being arranged vertically at intervals, the second mounting plate 214 being located above the first mounting plate 213, the first slide rail 211 being disposed on the top surface of the first mounting plate 213, and the second slide rail 212 being disposed on the bottom surface of the second mounting plate 214, such that the first slide rail 211 and the second slide rail 212 are distributed between the first mounting plate 213 and the second mounting plate 214, resulting in a compact structure, reducing the space occupied, and facilitating the design of the height difference between the second push plate 240 and the first push plate 220, thus reducing the number of parts.

[0061] An embodiment of the second aspect of the present invention proposes an automated printing device having multiple modules, including a certificate feeding module, a first printing module, a second printing module, etc., capable of continuously and automatically completing multiple printing tasks. A transfer mechanism is located at the output end of each module. The buffer rack 120 of the transfer mechanism has multiple layers of storage space 121 to accommodate certificates. When the next module malfunctions or stops, the buffer rack 120 can be used to temporarily store certificates. After the next module resumes normal operation, it can output certificates for continuous automated production, reducing downtime and improving production efficiency. Each module may have one transfer mechanism, or only some modules may have transfer mechanisms, depending on actual usage requirements.

[0062] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.

When the first push plate moves towards the buffer rack, the push block remains vertical to push the printed material. When the first push plate moves away from the buffer rack, the push block can rotate to avoid contact with the printed material. The second drive component includes a second motor, a drive wheel, a driven wheel, and a timing belt. The second motor is fixed to the base and located at one end of the first slide rail. The drive wheel is fixed to the output shaft of the second motor. The driven wheel is rotatably connected to the base and located at the other end of the first slide rail. The timing belt connects the drive wheel and the driven wheel. The first push plate is fixedly connected to the timing belt via a first support arm. The third drive component has the same structure as the second drive component. The base has a first mounting plate and a second mounting plate arranged vertically at intervals. The first slide rail is located on the top surface of the first mounting plate, and the second slide rail is located on the bottom surface of the second mounting plate.

2. The handover mechanism according to claim 1, characterized in that, The first module has a first controller, and the second module has a second controller. The first controller is communicatively connected to the second controller. The first controller controls the operation of the first conveying component, the first driving component, the second driving component, and the third driving component, and the second controller controls the operation of the second conveying component.

3. The handover mechanism according to claim 2, characterized in that, The first conveying assembly includes a first conveyor belt and a guide wheel. The first conveyor belt is provided with multiple sets of positioning blocks. Each set of positioning blocks defines a slot to accommodate the printed material. The guide wheel is adjacent to the buffer rack. When the first push plate contacts the printed material, the positioning block in front of the printed material deflects around the guide wheel to a position lower than the printed material. The structure of the second conveying assembly is the same as that of the first conveying assembly.
