Abstract
Description
Technical Field
[0001] This utility model relates to the field of defect detection technology for controlled bottles, specifically a rotating defect detection and rejection device for controlled bottles. Background Technology
[0002] As the core container for pharmaceutical packaging, the quality defects of controlled-volume bottles directly threaten drug safety and efficacy. Efficient and accurate defect detection systems play an irreplaceable role in ensuring drug quality, protecting patient health, and safeguarding the reputation of pharmaceutical companies. Modern detection primarily relies on highly automated machine vision technology. The system employs a multi-mode optical illumination scheme combining bright-field, backlighting, and dark-field illumination to specifically highlight different defect characteristics. For example, bright-field illumination can clearly capture surface foreign objects and stains, while backlighting effectively presents contour dimensional deviations and bottle mouth defects. The detection system is deeply integrated into the production line, achieving high-speed, real-time online full inspection, automatically rejecting defective products and recording traceability data, significantly improving detection efficiency and reliability, and ensuring that products leaving the factory meet stringent pharmaceutical GMP quality standards.
[0003] In subsequent transport, defective control bottles are typically pushed out of the transport mechanism by a lever and onto the conveyor belt of the defect rejection device. The defective control bottles are then transported forward on the conveyor belt of the defect rejection device for collection. However, the conveyor belt of the defect rejection device is relatively wide, and the bottles have lateral inertia when pushed onto the conveyor belt. The bottles are guided by inclined baffles, but if the bottles are unobstructed in the opposite direction of the baffles, they may wobble and tip over, making subsequent collection inconvenient. Therefore, we propose a control bottle rotation detection defect rejection device. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a rotating detection and rejection device for controlled bottles. By restricting the position of the bottle, the possibility of the bottle tipping over is reduced, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotating detection and rejection device for defects in tubular bottles, comprising a frame, an anti-tipping mechanism, and a pushing mechanism; The frame is fixedly connected to the upper end of the frame. The conveyor belt is installed inside the conveyor frame. The rear end of the conveyor frame is fixedly connected to the rear side baffle. The front end of the conveyor frame is fixedly connected to the stacking plate. The middle part of the conveyor frame is equipped with a limit mechanism. The right side of the frame is equipped with cylinder four. The left side of the telescopic end of cylinder four is fixedly connected to a push block. The air inlet of cylinder four is connected to an external air pump. Anti-tipping mechanism: It includes a support frame, a baffle, a sliding column, a cylinder, and a clamping plate. The support frame is fixedly connected to the rear end of the bottom wall of the stacking plate. The upper end of the support frame is fixedly connected to the sliding columns that are symmetrically distributed on the left and right. The upper end of the baffle is a rectangular frame. The rectangular frame of the baffle is slidably connected between two sliding columns. The bottom wall of the rectangular frame of the baffle is fixedly connected to a cylinder. The lower end of the telescopic end of the cylinder is fixedly connected to a clamping plate. The air inlet of the cylinder is connected to an external air pump. Pushing mechanism: It is located at the front end of the stacking plate and reduces the possibility of bottle tipping by restricting the position of the bottle.
[0006] Furthermore, the anti-tipping mechanism also includes a second cylinder, which is fixedly connected to the upper end of the support frame. The telescopic end of the second cylinder is fixedly connected to the front side wall of the rectangular frame of the baffle. The air inlet of the second cylinder is connected to an external air pump to drive the tubular bottle through the inclined platform.
[0007] Furthermore, the anti-tipping mechanism also includes a photoelectric sensor, which is fixedly connected to the lower end of the baffle via a fixing bracket. The photoelectric sensor corresponds to the left and right positions of the gap between the baffle and the clamp. The photoelectric sensor is bidirectionally electrically connected to an external controller to detect the position of the control bottle.
[0008] Furthermore, the limiting mechanism includes cylinder one, limiting rods, tripod one, and tripod two. Tripod two is fixedly connected to the right side of the frame. Cylinder four corresponds to the gap between the rear baffle and tripod two. A cylinder mounting bracket is fixedly connected to the left side of the frame. Cylinder one is fixedly connected to the left side of the cylinder mounting bracket. Tripod one is fixedly connected to the right side of the telescopic end of cylinder one. A limiting rod symmetrically distributed front and rear is fixedly connected to the left side of tripod one. The left ends of the limiting rods are slidably connected to the through holes of the cylinder mounting bracket. Tripod one and tripod two are located between the rear baffle and the stacking plate to limit the movement of the tubular bottles on the conveyor belt.
[0009] Furthermore, the pushing mechanism includes a pusher plate, a slider, a rodless cylinder, and a limiting post. The rodless cylinder and the limiting post are both fixedly connected between the left and right ends of the stacking plate. The rodless cylinder is located at the rear end of the limiting post. A slider is slidably connected to the outer surface of the limiting post. The rear end of the bottom surface of the slider is fixedly connected to the upper surface of the outer slider of the rodless cylinder. A pusher plate is fixedly connected to the rear side of the slider. The air inlet of the rodless cylinder is connected to an external air pump, which pushes the tubular bottle to move to the right.
[0010] Furthermore, the feeding mechanism also includes a baffle bar, which is fixedly connected to the front end of the bottom wall of the stacking plate. The baffle bar is located at the rear end of the rodless cylinder to prevent the tubular bottle from touching the rodless cylinder.
[0011] Furthermore, a ramp is fixedly connected to the middle of the frame, and the front end of the ramp contacts the rear end of the bottom wall of the stacking plate, so that the tubular bottles can be smoothly transitioned.
[0012] Furthermore, both ends of the frame are rotatably connected to a transmission shaft, and the two transmission shafts are connected by a transmission belt. A motor is fixedly connected to the rear end of the left side of the frame. The output shaft of the motor is fixedly connected to the left end of the rear transmission shaft. The input end of the motor is electrically connected to the output end of an external controller to drive the transmission belt to rotate.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This rotating defect detection and rejection device for tubular bottles has the following advantages: As the defective control bottle is removed by cylinder four and moved forward by the conveyor belt, tripod one is pushed to the right by cylinder one. The distance between the inclined plane of tripod one and the inclined plane of tripod two is slightly larger than the diameter of the control bottle. When the control bottle moves to the front of the inclined platform, it is clamped between the baffle and the clamping plate, and then sent to the bottom wall of the stacking plate. Finally, it is pushed away from the baffle by the push plate. The control bottle has little room to move throughout the process, which reduces the possibility of the control bottle shaking and the amplitude of shaking, and reduces the possibility of tipping.

A symmetrically distributed limiting rod 62 is fixedly connected to the left side of the tripod 63. The left ends of the limiting rods 62 are slidably connected to the through holes of the cylinder mounting bracket. Tripod 63 and tripod 64 are located between the rear baffle 5 and the stacking plate 8. A ramp 10 is fixedly connected to the middle of the frame 1. The front end of the ramp 10 contacts the rear end of the bottom wall of the stacking plate 8. Both the front and rear ends of the frame 1 are rotatably connected to... Two conveyor shafts are connected by a conveyor belt 3. A motor 4 is fixedly connected to the rear end of the left side of the frame 1. The output shaft of the motor 4 is fixedly connected to the left end of the rear conveyor shaft. The input end of the motor 4 is electrically connected to the output end of an external controller. Cylinder 4 11 is installed on the right side of the bottle conveyor belt, and the frame 1 is placed on the left side of the bottle conveyor belt. The push plate of cylinder 4 11 is aligned with the gap between the tripod 2 64 and the rear baffle 5. When a defective bottle is detected, the external controller records its position. When the defective bottle moves to the left side of cylinder 4 11, the telescopic end of cylinder 4 11 extends, and the defective bottle... The control bottle is pushed onto the conveyor belt 3. The output shaft of the motor 4 drives the rear conveyor shaft to rotate, which in turn drives the conveyor belt 3 to rotate. The conveyor belt 3 transports the defective control bottle forward. The telescopic end of cylinder 61 extends out, and tripod 63 is pushed to the right. The limit rod 62 moves synchronously to provide support for tripod 63, making the movement of tripod 63 more stable. The inclined plane of tripod 63 is parallel to the inclined plane of tripod 64 and the relative distance is slightly greater than the maximum diameter of the control bottle. The front end of the inclined plane of tripod 64 tilts to the left, causing the defective control bottle to slide forward and to the left at the same time. Anti-tipping mechanism 7 includes a support frame 71, a baffle 73, sliding columns 74, a third cylinder 76, and a clamping plate 77. The support frame 71 is fixedly connected to the rear end of the bottom wall of the stacking plate 8.

The upper end of the baffle 73 is a rectangular frame, which is slidably connected between two sliding columns 74. The bottom wall of the rectangular frame of the baffle 73 is fixedly connected to the third cylinder 76. The lower end of the telescopic end of the third cylinder 76 is fixedly connected to the clamping plate 77. The air inlet of the third cylinder 76 is connected to an external air pump. The anti-tipping mechanism 7 also includes a second cylinder 72, which is fixedly connected to the upper end of the support frame 71. The telescopic end of the second cylinder 72 is fixedly connected to the front side wall of the rectangular frame of the baffle 73. The air inlet of the second cylinder 72 is connected to an external air pump. The anti-tipping mechanism 7 also includes a photoelectric sensor 75. The photoelectric sensor 75 is fixedly connected to the lower end of the baffle 73 by a fixing bracket. The photoelectric sensor 75 corresponds to the left and right positions of the gap between the baffle 73 and the clamping plate 77. The photoelectric sensor 75 is bidirectionally electrically connected to the external controller. When a defective control bottle is about to move to the inclined platform 10, it is blocked by the baffle 73. The photoelectric sensor 75 is a reflective sensor that can detect transparent bottles. The photoelectric sensor 75 sends the information of detecting the control bottle to the external controller. The external controller controls the external air pump, the extension end of the cylinder 3 76 is pushed out, the clamping plate 77 moves down, and the control bottle is clamped between the clamping plate 77 and the baffle 73. Then the extension end of the cylinder 2 72 is retracted, and the whole composed of the clamping plate 77 and the baffle 73 moves backward between the sliding columns 74, bringing the control bottle from the inclined platform 10 to the stacking plate 8. The inclined surface of the inclined platform 10 makes the transition of the control bottle smoother. Pushing mechanism 9: Located at the front end of stacking plate 8, pushing mechanism 9 includes push plate 91, slider 92, rodless cylinder 94, and limiting post 95. Rodless cylinder 94 and limiting post 95 are fixedly connected between the left and right ends of stacking plate 8. Rodless cylinder 94 is located at the rear end of limiting post 95. Slider 92 is slidably connected to the outer surface of limiting post 95. The rear end of the bottom surface of slider 92 is fixedly connected to the upper surface of the outer slider of rodless cylinder 94. Push plate 91 is fixedly connected to the rear side of slider 92. Air inlet of rodless cylinder 94 is connected to an external air pump. (Rodless cylinder 94 adopts a magnetically coupled rodless cylinder commonly used in existing technology. The piston of rodless cylinder 94 has a built-in high-strength magnet.) The ring, with magnetic lines of force penetrating the cylinder and forming magnetic coupling with the external magnetic ring, when the air pressure pushes the piston, the external slider moves synchronously due to the magnetic attraction effect. The external slider drives the slider 92 to slide on the outer surface of the limiting post 95. The pushing mechanism 9 also includes a stop bar 93, which is fixedly connected to the front end of the bottom wall of the stacking plate 8. The stop bar 93 is located at the rear end of the rodless cylinder 94. The rodless cylinder 94 drives the push plate 91 and the slider 92 to slide to the right on the limiting post 95. The push plate 91 pushes the control bottle away from the stop plate 73. The control bottle is pushed to the right side of the stacking plate 8. The stop bar 93 blocks the control bottle to prevent the stacking plate 8 from pushing too many control bottles and causing the control bottle to touch the rodless cylinder 94.
[0018] The working principle of the rotary defect detection and rejection device for controlled bottles provided by this utility model is as follows: Cylinder 4 (11) is installed on the right side of the controlled bottle conveyor belt, and the frame 1 is placed on the left side of the conveyor belt. The push plate of cylinder 4 (11) is aligned with the gap between the tripod 2 (64) and the rear baffle 5. When a defective controlled bottle is detected, the external controller records its position. When the defective controlled bottle moves to the left side of cylinder 4 (11), the telescopic end of cylinder 4 (11) extends, and the defective controlled bottle is pushed onto the conveyor belt 3. The output shaft of motor 4 drives the rear transmission shaft to rotate, which in turn drives the conveyor belt 3 to rotate. The conveyor belt 3 transports the defective tubular bottle forward. The telescopic end of cylinder 1 61 extends, and tripod 1 63 is pushed to the right. The limit rod 62 moves synchronously, providing support for tripod 1 63 and making its movement more stable. The inclined plane of tripod 1 63 is parallel to the inclined plane of tripod 2 64, and the relative distance is slightly greater than the maximum diameter of the tubular bottle. The front end of the inclined plane of tripod 2 64 tilts to the left, causing the defective tubular bottle to slide forward and to the left. When the defective tubular bottle is about to move to the inclined platform 10, it is blocked by the baffle 73. The photoelectric sensor 75 is a reflective sensor that can detect transparent bottles. The photoelectric sensor 75 sends the information of detecting the tubular bottle to the external controller. The external controller controls the external air pump, and the telescopic end of cylinder 3 76 extends. The clamping plate 77 moves down, and the tubular bottle is clamped between the clamping plate 77 and the baffle 73. Then the telescopic end of cylinder 2 72 retracts. The clamping plate 77 and the baffle 73 move backward between the sliding column 74, bringing the control bottle from the inclined platform 10 to the stacking plate 8. The inclined surface of the inclined platform 10 makes the transition of the control bottle smoother. Then, the rodless cylinder 94 drives the push plate 91 and the slider 92 to slide to the right on the limit post 95. The push plate 91 pushes the control bottle away from the baffle 73. The control bottle is pushed to the right side of the stacking plate 8. The baffle 93 blocks the control bottle to prevent the stacking plate 8 from pushing too many control bottles and causing the control bottle to touch the rodless cylinder 94.
[0019] It is worth noting that the photoelectric sensor 75 disclosed in the above embodiments can be a PRK328.3 / 4P-M12 reflective photoelectric sensor, and the motor 4 can be freely configured according to the actual application scenario. The external controller controls the operation of the photoelectric sensor 75 and the motor 4 using methods commonly used in the prior art.
