Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical production technology, and in particular to a device for rejecting abnormal filling quantities in granule inner packaging equipment. Background Technology

[0002] In the production of granules, the accuracy of the inner packaging's fill volume is crucial. Abnormal fill volume not only affects product quality but may also trigger consumer trust crises and regulatory issues. Traditional methods for inspecting granule inner packaging have many shortcomings. Manual inspection is inefficient and prone to errors due to human factors, making it difficult to meet the needs of large-scale production. While some simple automatic inspection devices can achieve a certain degree of automation, they lack precise functions for rejecting products with abnormal fill volumes, failing to promptly separate substandard products from the production process. This results in substandard products being mixed into subsequent processes, increasing production costs and the defect rate. Furthermore, existing devices lack effective monitoring of the packaging bag's conveying status during operation, making it difficult for operators to promptly grasp the equipment's operating status and product quality information, which is detrimental to production management and quality control.

[0003] Therefore, it is necessary to provide a new granule inner packaging equipment with an abnormal filling amount rejection device to solve the above-mentioned technical problems. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figures 1-5 ,in, Figure 1 A three-dimensional structural schematic diagram of the granule inner packaging equipment abnormal filling rejection device provided by this utility model; Figure 2 This is an exploded structural diagram of the feeding and conveying mechanism provided by this utility model; Figure 3 This is an exploded structural diagram of the material feeding and conveying mechanism provided by this utility model; Figure 4 This is an exploded structural diagram of the weighing mechanism provided by this utility model; Figure 5 A schematic diagram of the anomaly removal mechanism provided by this utility model.

[0022] In the specific implementation process, such as Figures 1-5 As shown, the granule inner packaging equipment with abnormal filling quantity rejection device includes a workbench 1, a feeding conveyor mechanism 2, a weighing mechanism 3, a discharging conveyor mechanism 4, an abnormal rejection mechanism 5, an L-shaped bracket 6, a camera 7, a controller 28, and an alarm 29.

[0023] A feeding conveyor 2 is fixedly installed on one side of the top of the workbench 1 to transport the granule inner packaging products to be tested to the weighing mechanism 3. The weighing mechanism 3 is located on one side of the feeding conveyor 2, and it checks the fill weight of the passing granule inner packaging products. A discharging conveyor 4 is located on the side of the weighing mechanism 3 away from the feeding conveyor 2, to continue transporting the tested products to subsequent processes. An abnormality rejection mechanism 5 is located on one side of the discharging conveyor 4; when an abnormal fill weight is detected, it is rejected. An L-shaped bracket 6 is also installed on the top of the workbench 1, and a camera 7 (using a Hikvision MV-CA050-10GM industrial camera) is mounted on the L-shaped bracket 6 to detect whether any packaging bags are being transported on the weighing mechanism 3. A controller 28 is located on the top of the L-shaped bracket 6, and an alarm 29 is located on the top of the controller 28.

[0024] The feeding and conveying mechanism 2 includes a first support 8, a first driving roller 9, a first driven roller 10, a first conveyor belt 11, and a first motor 12. The first support 8 is fixedly installed on the top of the workbench 1, providing support for the entire feeding and conveying mechanism 2. The first driving roller 9 and the first driven roller 10, which are arranged in pairs with the first driving roller 9, are rotatably connected to the first support 8. The first conveyor belt 11 is disposed between the first driving roller 9 and the first driven roller 10. The first motor 12 is mounted on the first support 8, and the output shaft of the first motor 12 is fixedly connected to the first driving roller 9.

[0025] When the device is started, the first motor 12 begins to run, driving the first drive roller 9 to rotate, which in turn drives the first driven roller 10 to rotate via the first conveyor belt 11, thereby conveying the granular packaged products. The feeding and conveying speed can be adjusted by controlling the rotation speed of the first motor 12.

[0026] The weighing mechanism 3 includes a third support 18, a third drive roller 19, a third driven roller 20, a third conveyor belt 21, a third motor 22, and a weighing sensor 23. Weighing sensors 23 are installed at the four corners of the third support 18 between it and the worktable 1. The weighing sensors 23 can accurately measure the weight of the granule inner packaging product placed on the weighing mechanism 3. The third drive roller 19 and the third driven roller 20, which are paired with the third drive roller 19, are rotatably connected to the third support 18. The third conveyor belt 21 is positioned between the third drive roller 19 and the third driven roller 20. The third motor 22 is mounted on the third support 18, and the output shaft of the third motor 22 is fixedly connected to the third drive roller 19. The weighing sensor 23 is a Fuji 003L weighing sensor, which can accurately measure the weight of the granule inner packaging product.

[0027] When the granule inner packaging product is conveyed from the feeding conveyor 2 to the third conveyor belt 21 of the weighing mechanism 3, the weighing sensor 23 detects the weight of the product in real time and transmits the weight signal to the controller 28. At the same time, the third motor 22 drives the third drive roller 19 to rotate, so that the third conveyor belt 21 continues to convey the product to the unloading conveyor 4.

[0028] The material feeding and conveying mechanism 4 includes a second support 13, a second driving roller 14, a second driven roller 15, a second conveyor belt 16, and a second motor 17. The second support 13 is fixedly installed on the top of the workbench 1, providing support for the material feeding and conveying mechanism 4. The second driving roller 14 and the second driven roller 15, which are arranged in pairs with the second driving roller 14, are rotatably connected to the second support 13. The second conveyor belt 16 is disposed between the second driving roller 14 and the second driven roller 15. The second motor 17 is mounted on the second support 13, and the output shaft of the second motor 17 is fixedly connected to the second driving roller 14.

[0029] The second motor 17 drives the second active roller 14 to rotate, which in turn drives the second driven roller 15 to rotate via the second conveyor belt 16, thus conveying the weighed and inspected granule inner packaging products to subsequent processes or to be rejected by the abnormal rejection mechanism 5.

[0030] The abnormal rejection mechanism 5 includes a fixed plate 24, a cylinder 25, a push plate 26, and a guide rod 27. The fixed plate 24 is fixedly installed on the top of the worktable 1, the cylinder 25 is fixedly installed on the worktable 1, the push plate 26 is fixedly connected to the piston rod of the cylinder 25, and the guide rod 27 is fixedly connected to the push plate 26 and slidably connected to the fixed plate 24.

[0031] When the controller 28 determines that the weight of the granule packaged product detected by the weighing sensor 23 exceeds or falls below the set normal range, the controller 28 sends a control signal to the cylinder 25. The piston rod of the cylinder 25 extends, pushing the push plate 26 to move along the guide rod 27, thus removing the abnormally filled product from the feeding conveyor mechanism 4. The guide rod 27 ensures the smoothness and accuracy of the push plate 26's movement.

[0032] The camera 7 captures images of the weighing mechanism 3 in real time and transmits the image signals to the controller 28.

[0033] The controller 28 is a Siemens S7-1200 series PLC programmable logic controller. Controller 28 can receive signals from camera 7, weighing sensor 23, first motor 12, second motor 17, and third motor 22, and perform logical judgments and control according to a preset program. An alarm 29 is installed on the top of controller 28; this is an audible and visual alarm. When an abnormal filling amount is detected, controller 28 controls alarm 29 to emit an alarm signal. Simultaneously, controller 28 can also display the weight of the packaging bag and the number of times the camera 7 has detected the packaging bag, allowing operators to monitor production status in real time.

[0034] The working principle of this utility model is as follows: Upon starting the device, the first motor 12, the second motor 17, and the third motor 22 begin operation, driving the feeding conveyor 2, the weighing mechanism 3, and the unloading conveyor 4. The granule-packaged product is conveyed via the feeding conveyor 2 to the third conveyor belt 21 of the weighing mechanism 3. The camera 7 detects in real-time whether any packaging bags are being conveyed on the weighing mechanism 3 and transmits the image signal to the controller 28. The weighing sensor 23 detects the weight of the product in real-time and transmits the weight signal to the controller 28. The controller 28 judges the weight signal. If the weight is within the normal range, the product continues to be conveyed to the subsequent process via the unloading conveyor 4; if the weight exceeds or falls below the normal range, the controller 28 controls the cylinder 25 to actuate, using the push plate 26 to remove the abnormal product and controls the alarm 29 to sound an alarm. Simultaneously, the controller 28 displays the weight of the packaging bag and the number of times the camera 7 detects the packaging bag passing through in real-time. Operators can observe the information displayed on the controller 28 to understand the real-time operation of the device.

[0035] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
