Description

Technical Field

[0001] This utility model relates to a waste paper cleaning structure on a roller die-cutting machine, specifically to a bottle inversion detection mechanism. Background Technology

[0002] During the packaging process, medicine bottles are conveyed by a conveyor belt and arranged in a layout that fits the inner cavity of the packaging box. The bottles must be kept upright while being conveyed by the conveyor belt, but manual monitoring can easily miss bottles tipping over, leading to packaging interruptions or equipment damage. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a bottle-tipping detection mechanism that automatically detects bottle tipping and triggers an alarm by combining mechanical triggering with photoelectric sensing.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a bottle inversion detection mechanism, comprising: The frame is equipped with parallel conveyor belts and limiting baffles located on the sides of the conveyor belts, forming a conveying channel for single bottles to pass through between adjacent baffles. The detection component includes: The crossbars are mounted on top of the frame via mounting plates on both sides; Hanging plate, fixed to the limiting baffle and provided with sleeve hole for connecting cross bar, with limiting sleeve between hanging plates; A horizontal plate is installed between mounting plates and has a mounting groove corresponding to the conveyor channel. An L-shaped detection plate that can rotate around the horizontal axis is installed in the groove. The detection plate includes a horizontal base plate and a vertical plate. The distance between the base plate and the conveyor belt is adapted to the height of the medicine bottle and the length is ≥ twice the diameter of the medicine bottle. When the medicine bottles are arranged in this way, the detection plate can always be supported and kept stable. A photodetector is installed at the vertical plate position corresponding to the detection plate and is electrically connected to the controller to detect whether the vertical plate is in an obstructed state.

[0005] The limiting baffle is adjustablely fitted onto the crossbar through the sleeve hole of the hanging plate.

[0006] When no medicine bottle passes by, the bottom plate of the detection plate is tilted due to the gravity of the vertical plate. When the medicine bottle passes by normally, the bottom plate horizontally supports the medicine bottle so that the vertical plate keeps blocking the photoelectric detector.

[0007] The photodetector is a diffuse reflection or through-beam sensor, and its signal output terminal is connected to the alarm device.

[0008] The number of transmission channels is multiple, and each channel corresponds to a detection board.

[0009] The beneficial effects of this utility model are: it enables real-time detection and alarm of bottle inversion, reduces reliance on manual labor, avoids packaging failures, and the detection plate self-resets by gravity, making the response sensitive and reliable.

Detailed Implementation

[0013] The present invention will be described in detail below through embodiments, which are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention.

[0014] like Figure 1 — Figure 4 As shown in the figure, this embodiment discloses a bottle inversion detection mechanism.

[0015] I. Overall Structure Overview This bottle-tipping detection mechanism is mainly used to detect overturned medicine bottles conveyed on a conveyor belt during the pharmaceutical packaging process. This ensures the smooth operation of the packaging process and prevents bottle tipping from affecting the packaging process and damaging the equipment. The mechanism mainly consists of a frame, conveyor belt, limit baffles, and detection components. All parts work together to achieve accurate detection of overturned bottles and timely alarms.

[0016] II. Detailed Structure and Connection Relationships of Each Component 1 rack Frame 1 is the fundamental support component of the entire bottle-tipping detection mechanism, providing the mounting base for other components. It possesses sufficient strength and stability to withstand the weight of the conveyor belt, medicine bottles, and other components, as well as the forces exerted during operation. The frame is typically made of metal materials such as steel and assembled into a monolithic frame structure through welding, bolting, or other methods.

[0017] 2 Conveyor Belt Conveyor belts 2 are mounted on frame 1, and multiple belts are arranged in parallel. The conveyor belt is a key component in the transport of medicine bottles, its function being to smoothly move the bottles from one position to another. Conveyor belts are generally made of rubber or other materials with good wear resistance and friction, and their surface has a certain degree of roughness to ensure that the bottles do not slip during transport. The conveyor belt is driven by a motor, but it is a conventional drive component. The motor drives the rollers of the conveyor belt to rotate, thus enabling the conveyor belt to operate. The speed of the motor can be adjusted using devices such as speed controllers to adapt to different packaging production needs.

[0018] 3 Limit baffle Limiting baffles 3 are installed on the sides of conveyor belts 2 and between them. The main function of the limiting baffles is to restrict the position of the medicine bottles during conveying, ensuring that the bottles can only be conveyed along specific channels, guaranteeing that the bottles are neatly arranged and forming a conveying channel for only one bottle at a time. The limiting baffles are typically made of plastic or thin metal sheets, possessing sufficient strength and rigidity to withstand minor collisions during conveying. The limiting baffles are installed on the frame 1 using bolts or other fixing methods. Their position can be adjusted according to the size of the medicine bottles and conveying requirements to ensure that the width of the conveying channel matches the diameter of the medicine bottles, allowing individual bottles to pass smoothly.

[0019] 4 Detection Components The detection component is the core of this bottle-inverting detection mechanism, used to detect whether a medicine bottle is inverted. It specifically includes the following components: 1. Crossbar The crossbar 4 is mounted above the frame 1 via mounting plates 5 on both sides. The mounting plates 5 are fixed to both sides of the frame 1 and securely connected to the frame via welding, bolting, or other methods. The crossbar 4 is horizontally installed between the mounting plates 5, providing support for subsequent mounting of components such as hanging plates and detection plates. The crossbar 4 is generally made of round metal rods, possessing sufficient strength and rigidity to withstand the weight of components such as hanging plates and detection plates.

[0020] 2. Hanging board The mounting plate 6 and the limiting baffle 3 are integrally formed, and each limiting baffle 3 is correspondingly provided with a mounting plate 6. The mounting plate 6 has a sleeve hole 61, the size of which matches the diameter of the crossbar 4, allowing the mounting plate 6 to be fitted onto the crossbar 4 through the sleeve hole 61. In this way, the mounting plate 6, along with the limiting baffle 3, can be adjusted to a certain extent along the crossbar 4 to adjust the position and width of the conveyor channel according to actual conditions. The mounting plate 6 and the limiting baffle 3 can be fixedly connected by welding, bolts, or other methods. Furthermore, a limiting sleeve 62 is fitted on the crossbar 4 between the mounting plates 6. The function of the limiting sleeve 62 is to limit the range of movement of the mounting plate 6 on the crossbar 4, preventing excessive movement of the mounting plate 6 that could cause abnormal positioning of the conveyor channel.

[0021] 3. Horizontal board A horizontal plate 7 is installed between two mounting plates 5, located below the crossbar 4. The horizontal plate 7 has mounting slots 71 corresponding one-to-one with the conveying channels. The number of mounting slots 71 is the same as the number of conveying channels, and their positions correspond one-to-one. Each mounting slot 71 contains a horizontal shaft 72, which is horizontally installed within the mounting slot 71. Its two ends are connected to the side wall of the mounting slot 71 via bearings or other fixing methods, allowing the horizontal shaft 72 to rotate freely within the mounting slot 71.

[0022] 4. Detection plate The detection plate 8 is fitted onto the horizontal axis 72 and can rotate around the horizontal axis 72. The detection plate 8 is L-shaped and includes a horizontal base plate 81 and a vertical plate 82. The height between the horizontal base plate 81 and the conveyor belt 2 is adapted to the height of the medicine bottle 11, that is, when the medicine bottle passes through normally upright, the bottom of the medicine bottle can contact the horizontal base plate 81. The length of the detection plate base plate 81 is not less than the diameter of two medicine bottles 11, which ensures that under normal circumstances, there are enough medicine bottles to support the detection plate base plate 81 and keep it in a stable tilted state. When no medicine bottle passes under the detection plate 8, the vertical plate 82 of the detection plate 8 tilts due to the gravity of the base plate 81. At this time, the vertical plate 82 deviates from the detection area of ​​the photoelectric detector 9; when a medicine bottle passes through normally, the bottom of the medicine bottle supports the detection plate base plate 81, keeping the detection plate 8 as a whole stable, and the vertical plate 82 is in a state of blocking the photoelectric detector 9.

[0023] 5. Photodetector The photodetector 9 is positioned corresponding to the vertical plate 82 of the detection plate 8, installed in a suitable location near the mounting slot 71 to ensure accurate detection of the state of the vertical plate 82. The photodetector 9 is connected to the controller 10. The photodetector 9 can be a diffuse reflection or through-beam sensor. A diffuse reflection photodetector determines whether the vertical plate 82 is obstructed by emitting light and receiving light reflected back from it. A through-beam photodetector emits light from its emitting end and receives it from its receiving end; when the vertical plate 82 obstructs the light, the receiving end receives no light, thus determining the state of the vertical plate 82. The photodetector 9 is used to detect whether the vertical plate 82 on the detection plate 8 remains vertical, i.e., whether it is obstructed. If the detection plate 8 tilts, for example, due to a bottle tipping over causing the medicine bottle to no longer support the bottom plate 81 of the detection plate, the detection plate 8, under its own gravity, will cause the vertical plate 82 to no longer obstruct the photodetector 9. If the photodetector 9 cannot detect the vertical plate 82 of the detection plate 8 or detects an abnormal position of the vertical plate 82, it can transmit a signal to the controller 10.

[0024] 6. Controller The controller 10 is connected to the photoelectric detector 9 and receives signals transmitted by the photoelectric detector 9. When the photoelectric detector 9 detects an abnormality in the state of the vertical plate 82 of the detection board 8, i.e., detects a bottle tipping, the controller 10 issues an alarm signal. The controller 10 can be a programmable logic controller (PLC) or other electronic equipment with signal processing and control functions. The alarm signal can be an audible and visual alarm, for example, by connecting a buzzer and a warning light. When a bottle tipping is detected, the buzzer sounds and the warning light flashes, reminding staff to handle the problem promptly.

[0025] III. Work Process During the pharmaceutical packaging process, the medicine bottle 11 is conveyed forward along the conveyor channel formed by the limiting baffle 3, driven by the conveyor belt 2. When the medicine bottle passes through upright, its bottom is supported on the horizontal base plate 81 of the detection plate 8. Due to the support of the medicine bottle, the detection plate 8 remains stable, and its vertical plate 82 is in a state of blocking the photoelectric detector 9. The photoelectric detector 9 detects that the vertical plate 82 is normally blocked, and the controller 10 does not issue an alarm signal. When the bottle tipps over, that is, the medicine bottle 11 tilts over during the conveying process and no longer supports the horizontal base plate 81 of the detection plate 8, the base plate 81 of the detection plate 8 loses its support and rotates under its own gravity, causing the vertical plate 82 to no longer block the photoelectric detector 9 or the position of the vertical plate 82 to change significantly. After detecting this change in state, the photoelectric detector 9 transmits a signal to the controller 10, and the controller 10 immediately issues an alarm signal to remind the staff that a bottle has tipped over. The staff can then take timely measures to right the bottle and ensure the normal progress of the packaging process. Through the coordinated operation of the above components, this bottle-tipping detection mechanism can accurately and promptly detect bottle tipping during the conveying process and issue an alarm, effectively solving various problems caused by bottle tipping in the pharmaceutical packaging process, improving packaging efficiency and quality, and reducing the risk of equipment damage.

[0026] By adopting the above technical solution, instant detection and alarm of bottle inversion can be achieved, reducing reliance on manual labor, avoiding packaging failures, and the detection plate can be self-reset by gravity, with a sensitive and reliable response.
