Description

Technical Field

[0001] This application relates to the field of weighing devices, and in particular to a non-stop weighing device for books used in Martini binding lines. Background Technology

[0002] Modern printing and binding production involves multiple processes, including printing, pasting, inserting, and sealing. Throughout the production process, human error, equipment malfunction, and insufficient equipment precision can all lead to discrepancies in the number of pasted pages in the final product.

[0003] The prior art publication CN220595964U provides a logistics anti-bounce conveyor belt with weighing function. This prior art logistics anti-bounce conveyor belt with weighing function includes: a base, a pressure sensor, a support, a drive roller located at one end of the inner top of the support, a driven roller located at the other end of the inner top of the support, a conveyor belt fitted with the drive and driven rollers, an anti-bounce device located inside the ring formed by the conveyor belt, a pressure sensor located between the base and the support, and an additional guide device, which is cylindrical, located at the top of the frame. The bottom of the connecting frame has several through holes, which cooperate with a limiting block at the top of the frame, enabling the pressure sensor to withstand force in one direction, thus improving weighing accuracy.

[0004] However, in this prior art, during the weighing process, the weighing mechanism needs to bear the weight of the entire conveying device, and is easily affected by the vibration of the motor, the vibration of the rollers and the vibration of the motor wires, which causes the weighing mechanism to be affected by a large amount of non-material weight and vibration, resulting in a decrease in weighing accuracy. Utility Model Content

[0005] To address the issue of pressure sensors being affected by significant vibrations during data acquisition, this application provides a non-stop weighing device for books used in Martini binding lines.

[0006] The technical solution provided in this application for a non-stop book weighing device for a Martini binding line is as follows: A non-stop book weighing device for a Martini binding line includes a conveying mechanism, a weighing mechanism, and a rotating mechanism. The conveying mechanism is mounted on a frame and is used to transport books. The weighing mechanism is mounted on the rotating mechanism and is capable of weighing the books. The rotating mechanism is mounted on the frame. The rotating mechanism can repeatedly drive the weighing mechanism to lift the book, so that the book is detached from the conveying mechanism. The rotating mechanism can repeatedly drive the weighing mechanism to lower the book, so that the book is placed on the conveying mechanism. The weighing mechanism can weigh the book in the detached state.

[0007] By adopting the above technical solution, without stopping the conveyor mechanism, the rotating mechanism drives the weighing mechanism to lift the books on the conveyor mechanism. The weight of the books can be fully applied to the weighing mechanism, allowing the weighing mechanism to weigh the books independently. Compared with the prior art, this application adopts a solution where the weighing mechanism weighs the books independently, eliminating the need to weigh the entire conveyor belt mechanism. This reduces the impact of non-material weight and vibration on the weighing mechanism and improves the weighing accuracy.

[0008] Preferably, the rotating mechanism includes a rotating frame, a transmission component, and a platform. The rotating frame is fixedly provided with a first rotating shaft, and the rotating frame is rotatably connected to the machine frame through the first rotating shaft. A second rotating shaft is rotatably provided on the rotating frame, and the platform is fixedly connected to the second rotating shaft. The transmission component is connected to the machine frame and the second rotating shaft, so that the platform can remain in a horizontal state during the rotation of the rotating frame.

[0009] By adopting the above technical solution, the rotating frame is rotatably connected to the machine frame via the first rotating shaft, and the second rotating shaft is fixedly connected to the platform. The transmission component is connected to the machine frame and the second rotating shaft, so that the platform remains horizontal during rotation, thereby improving the stability of the book during weighing.

[0010] Preferably, the rotating frame includes two rotating rods, which are arranged opposite each other on both sides of the platform. Each rotating rod is fixedly connected to the first rotating shaft and rotatably connected to the second rotating shaft.

[0011] By adopting the above technical solution, the rotating frame consists of two rotating rods, which are set on both sides of the platform to form a double-sided support for the platform, making the rotating frame and the platform more secure, thereby improving the stability of the platform during rotation.

[0012] Preferably, the transmission component includes a main sprocket, a driven sprocket, and a chain. The main sprocket is fixedly connected to the frame and coaxially arranged with the first rotating shaft. The driven sprocket is fixedly connected coaxially with the second rotating shaft. The chain meshes with the main sprocket and the driven sprocket to enable the platform to remain horizontal during the rotation of the rotating frame.

[0013] By adopting the above technical solution, the main sprocket, the driven sprocket and the chain are meshed and connected in the transmission component, so that the platform remains horizontal and the transmission is precise during rotation, thereby improving the accuracy of the rotation process.

[0014] Preferably, the weighing mechanism includes a wireless pressure sensor and a tray. The wireless pressure sensor is mounted on the platform and transmits the weighing signal to the display screen. The tray is mounted on the sensitive element of the wireless pressure sensor and is used to support the books.

[0015] By adopting the above technical solution, the book is supported by the tray on the wireless pressure sensor, so that the wireless pressure sensor only weighs the book. Moreover, the wireless pressure sensor is freed from the constraints of wiring and realizes dynamic detection, thereby improving the convenience of signal transmission of the weighing mechanism.

[0016] Preferably, the platform is equipped with a battery that powers the wireless pressure sensor.

[0017] By adopting the above technical solution, the wireless pressure sensor is powered by the battery on the platform, which simplifies the structure of the weighing mechanism and improves the convenience of powering the wireless pressure sensor.

[0018] Preferably, the conveying mechanism includes a drive motor, a drive roller, and a conveyor belt. The drive motor is mounted on the frame, and the output shaft of the drive motor is fixedly connected to the drive roller. The drive roller is rotatably mounted on the frame, and the conveyor belt is sleeved on the drive roller and moves synchronously with the drive roller to transport books.

[0019] By adopting the above technical solution, the conveyor belt is fitted onto the transmission roller, and the transmission roller is driven by the output shaft of the motor, so that the transmission roller and the conveyor belt move synchronously, thereby realizing the transport of books.

[0020] Preferably, there are two sets of conveyor belts, with a rotation space between the two sets of conveyor belts for the rotating mechanism to be placed. Books can be straddled on the two sets of conveyor belts, and the rotating mechanism can drive the weighing mechanism to lift the books on the conveyor belts.

[0021] By adopting the above technical solution, books can be straddled on two sets of conveyor belts. The weighing mechanism can lift the books on the conveyor belts, allowing the books to be weighed separately without stopping the conveyor belts, thus improving the convenience of weighing books.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Compared with the prior art, this application adopts a scheme in which the weighing mechanism weighs the books separately, eliminating the need to weigh the entire conveyor belt mechanism. This reduces the impact of non-material weight and vibration on the weighing mechanism and improves the weighing accuracy of the weighing mechanism. 2. The rotating frame consists of two rotating rods, which are fixedly connected to the first rotating shaft and rotatably connected to the second rotating shaft. The rotating frame is rotatably connected to the machine frame via the first rotating shaft and fixedly connected to the platform via the second rotating shaft. The main sprocket and the driven sprocket are connected by chain meshing, which makes the platform remain horizontal and the transmission precise during rotation, thereby improving the stability of the weighing mechanism and the rotation of the rotating frame. 3. The weighing mechanism adopts a simple combination of wireless pressure sensor and battery, which makes the structure of the weighing mechanism simpler and improves the convenience of signal transmission.

[0031] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0032] This application discloses a non-stop book weighing device specifically for Martini binding lines. Reference Figure 1 A non-stop book weighing device for a Martini binding line includes a conveying mechanism 3, a weighing mechanism 2, and a rotating mechanism 1. The conveying mechanism 3 is mounted on a frame 4 and is used to transport books. The weighing mechanism 2 is mounted on the rotating mechanism 1 and can drive the weighing mechanism 2 to rotate, thereby weighing the books.

[0033] The rotating mechanism 1 is mounted on the frame 4. The motor 41 drives the rotating mechanism 1 to rotate. The rotating mechanism 1 drives the weighing mechanism 2 to lift the books on the conveying mechanism 3, so that the books are detached from the conveying mechanism 3. The rotating mechanism 1 continues to drive the weighing mechanism 2 to drop the books on the conveying mechanism, so that the books are placed on the conveying mechanism 3. The weighing mechanism 2 can weigh the books in the detached state independently, without having to weigh the entire conveying mechanism 3. This reduces the impact of non-material weight and vibration on the weighing mechanism 2, and improves the weighing accuracy of the weighing mechanism 2.

[0034] Reference Figure 2 , Figure 3 The rotating mechanism 1 is mounted on the frame 4. The motor 41 drives the first rotating shaft 12 to rotate. The rotating rod 111 on the first rotating shaft 12 can drive the platform 15 to rotate. The platform 15 repeatedly drives the tray 22 to lift the book, so that the book is detached from the conveyor belt 33. The platform 15 repeatedly drives the tray 22 to drop the book, so that the book is placed on the conveyor belt 33. The wireless pressure sensor 21 can weigh the book in the detached state separately, without having to weigh the entire conveyor belt 33 mechanism. This reduces the impact of non-material weight and vibration on the weighing mechanism 2, and improves the weighing accuracy of the weighing mechanism 2.

[0035] Reference Figure 3 The conveying mechanism 3 includes a drive motor 31, drive rollers 32, and a conveyor belt 33. The drive motor 31 is mounted on one end of the frame 4. There are two drive rollers, which are arranged parallel to each other and rotatably mounted at both ends of the frame 4. One of the drive rollers is fixedly connected to the output shaft of the drive motor 31. There are two sets of conveyor belts 33, which are fitted onto the two drive rollers 32, enabling the drive motor 31 to drive the drive rollers 32 and the conveyor belts 33 to move synchronously, thus conveying the books. A rotation space 16 is left between the two sets of conveyor belts 33 for the rotating mechanism 1 to be placed, allowing the rotating mechanism 1 and the weighing mechanism 2 to rotate freely in the rotation space 16. A photoelectric sensor 34 is installed at the entrance of the conveying mechanism 3 to detect whether the book is on the conveyor belt 33.

[0036] The rotating mechanism 1 includes a rotating frame 11, a transmission component 14, and a platform 15. A motor 41 is fixedly mounted on the frame 4, and a first rotating shaft 12 is coaxially fixed on the output shaft of the motor 41. The rotating frame 11 includes two rotating rods 111, which are arranged opposite to each other. The first rotating shaft 12 passes through the two rotating rods 111 and is fixedly connected to them, so that the motor 41 drives the two rotating rods 111 to rotate through the first rotating shaft 12. A second rotating shaft 13 passes through the ends of the two rotating rods 111 and is rotatably connected to them. The platform 15 is located between the two rotating rods 111, and the second rotating shaft 13 passes through the platform 15, which is fixedly connected to it.

[0037] There are two sets of transmission components 14, each corresponding to one of the two rotating rods 111. The two sets of transmission components 14 are respectively positioned outside the corresponding rotating rods 111. The distance between the two sets of transmission components 14 is less than the length of the rotation space 16 perpendicular to the book conveying direction. Each transmission component 14 includes a main sprocket 141, a driven sprocket 142, and a chain 143. The main sprocket 141 and the driven sprocket 142 have the same parameters. The two main sprockets 141 are mounted on the first rotating shaft 12 and fixedly connected to the frame 4. The two driven sprockets 142 are sleeved on the second rotating shaft. The second rotating shaft 13 is fixedly connected to the second rotating shaft 13. Each chain 143 is sleeved on the corresponding main sprocket 141 and driven sprocket 142 and meshes with them. When the rotating rod 111 rotates, the main sprocket 141 and the frame 4 are stationary. The driven sprocket 142 drives the second rotating shaft 13 to rotate. The transmission direction of the second rotating shaft 13 relative to the rotating rod 111 is opposite to the transmission direction of the rotating rod 111 relative to the frame 4, so that the platform 15 remains horizontal and the transmission is precise during the rotation process, thereby improving the accuracy of the rotation process.

[0038] Reference Figure 4 , Figure 5 The weighing mechanism 2 includes a wireless pressure sensor 21 and a tray 22. The wireless pressure sensor 21 is mounted on the platform 15, and a battery 23 is fixedly mounted below the platform 15. The battery 23 continuously supplies power to the wireless pressure sensor 21 through wires. The tray 22 is mounted on the sensitive element of the wireless pressure sensor 21, so that the wireless pressure sensor 21 only weighs the books. After the wireless pressure sensor 21 converts the pressure of the books into digital signals, it sends them to the display screen in the form of electromagnetic waves through a wireless module, and finally displays the pressure data on the display screen.

[0039] Reference Figure 5 , Figure 6 , Figure 7When the book is at the first position 5 on the conveyor belt 33, the motor 41 drives the first rotating shaft 12 to rotate, so that the rotating rod 111 on the first rotating shaft 12 can drive the platform 15 to rotate. The platform 15 drives the tray 22 to lift the book, so that the book is detached from the conveyor belt 33. In the detached state, the wireless pressure sensor 21 can weigh the book independently. After the weighing is completed, the rotating rod 111 continues to drive the platform 15 to rotate, and the platform 15 drives the tray 22 to drop the book, so that the book is placed on the second position 6 on the conveyor belt 33. After the book is placed on the second position 6, the motor 41 continues to drive the first rotating shaft 12, driving the platform 15 and the tray 22 back to the first position 5, ready for the next book weighing, thereby realizing the cyclical automatic weighing operation.

[0040] The implementation principle of the ultrasonic detection device for preventing multiple sheets of paper from overlapping in a printing press according to an embodiment of this application is as follows: When the book is conveyed to the first position 5 of the conveyor belt 33 by the photoelectric sensor 34, the motor 41 drives the first rotating shaft 12 to rotate. The first rotating shaft 12 drives the two rotating rods 111 to rotate, causing the platform 15 to rotate with the rotating rods 111. The platform 15 drives the tray 22 to lift the book, so that the book is detached from the conveyor belt 33. When the rotating rods 111 rotate, the main sprocket 141 and the frame 4 are stationary. The sprocket 142 drives the second rotating shaft 13 to rotate. The transmission direction of the second rotating shaft 13 relative to the rotating rods 111 is opposite to the transmission direction of the rotating rods 111 relative to the frame 4, so that the platform 15 remains horizontal during rotation. In the detached state, the wireless pressure sensor 21 can weigh the book independently.

[0041] After weighing, motor 41 continues to drive rotating rod 111 to rotate, and platform 15 drives tray 22 to drop the book, placing it on the second position 6 on conveyor belt 33. Wireless pressure sensor 21 can weigh the book in the detached state independently, without needing to weigh the entire conveyor belt 33 mechanism. This reduces the impact of non-material weight and vibration, improving the weighing accuracy of wireless pressure sensor 21.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
