Description

Vision-based bottle-inverting detection device for beverage production lines Technical Field

[0001] This utility model relates to the technical field of production line detection devices, and in particular to a bottle-inverting detection device for beverage production lines based on visual inspection. Background Technology

[0002] In modern industrial production, especially in automated production lines for wine bottling and subsequent labeling, the process of transporting empty bottles to the bottling machine and then transporting the finished bottles after filling and capping is extremely complex. Because production lines are designed with long and winding conveyor belts to achieve efficient storage and transport, empty or finished bottles are prone to tipping over due to various random factors during transport.

[0003] The process and shape of a bottle falling over vary significantly depending on the factors causing it to tip over. For example, when the conveyor belt speed is unstable, the bottle may suddenly slide or jump due to inertia, then lose balance and fall over. When the conveyor belt screws are loose, causing an uneven surface, the bottle may trip over uneven pressure when encountering a bump or depression, leading to it tipping over. Abnormalities in the guardrails, such as protruding parts, can obstruct the bottle's normal movement, causing it to be scraped and fall over.

[0004] Currently, visual inspection technology is widely used to detect and identify overturned bottles on conveyor belts, whether empty or finished. For example, Chinese patent application CN202510025810.0 discloses a fully automated tissue culture bottle filling line and its control method. The line covers stations such as feeding, bottle loading, bottle sorting, overturning, degreasing, cleaning, filling, capping, unloading, transfer, and sterilization. It utilizes robotic arms and conveyor lines to automate the tissue culture bottle processing. The overturning station uses image recognition algorithms to accurately detect and process overturned bottles. The visual inspection mechanism includes image acquisition, preprocessing, and feature extraction and matching steps. Camera parameters are optimized based on conveyor speed and light intensity. Composite filtering and correction algorithms improve image quality, and multi-feature vectors are extracted and input into the model to determine the bottle posture.

[0005] Typically, when bottle tipping occurs repeatedly, the conveyor belt needs to be inspected. In the ultra-high-speed operation of wine production lines, where the volume can reach 50,000 to 60,000 bottles per hour, it is difficult for the human eye to capture the instantaneous details of bottle tipping. Existing visual inspection agencies can only detect whether empty or finished bottles have tipped over, and cannot assist maintenance personnel in analyzing the root cause of the tipping. During inspection, maintenance personnel need to check the cause one by one, which is time-consuming and labor-intensive, reducing maintenance efficiency. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a visual inspection-based bottle tipping detection device for beverage production lines, which can provide a reliable basis for analyzing the causes of bottle tipping, thereby improving maintenance efficiency and ensuring the stable operation of the production line.

[0007] This utility model is implemented as follows: This utility model provides a visual inspection-based bottle-inverting detection device for beverage production lines, which is installed at the bottle-inverting position of the beverage production line. The detection device includes a movable support, a high-speed camera, a high-speed video camera, and a computer.

[0008] The high-speed camera, high-speed video camera, and computer are all mounted on a mobile support.

[0009] Both the high-speed camera and the high-speed video camera are connected to the computer.

[0010] The high-speed camera is used to capture and record the flow of bottles at the current location on the beverage production line. When a bottle tipping occurs on the beverage production line, maintenance personnel can use a computer to play back the footage recorded by the high-speed camera to determine the cause of the tipping.

[0011] Furthermore, the mobile support includes a base plate, a telescopic rod, a computer mounting plate, and a camera mounting plate; the high-speed camera and high-speed video camera are fixed on the camera mounting plate, and the computer is mounted on the computer mounting plate;

[0012] The bottom of the base plate is provided with movable wheels, the telescopic rod is vertically provided on the top of the base plate, the top of the telescopic rod is provided with a first connecting block, the first connecting block is provided with a pin, the bottom of the camera fixing plate is provided with a second connecting block, the second connecting block is hinged to the pin, and the second connecting block is also connected to a locking component for locking the second connecting block.

[0013] The computer placement board is slidably connected to the telescopic rod.

[0014] Furthermore, the telescopic rod includes a fixed rod and a sliding rod. The fixed rod is fixedly connected to the base plate. The first connecting block is disposed at the upper end of the sliding rod. The sliding rod is sleeved in the inner cavity of the fixed rod and is slidably connected to the fixed rod. A set screw is spirally connected to the outer wall of the fixed rod. The set screw passes through the fixed rod and abuts against the outer wall of the sliding rod.

[0015] Furthermore, the first connecting block has an arc-shaped groove, and the locking device includes a locking screw, which passes through the arc-shaped groove and is spirally connected to the second connecting block.

[0016] Furthermore, the computer placement board includes a shelf, a connecting rod, and a ring. The shelf is fixed to the upper end of the connecting rod, and the ring is fixed to the lower end of the connecting rod. The ring is slidably connected to the outer wall of the telescopic rod, and a fixing screw is spirally connected to the ring. The fixing screw passes through the ring and abuts against the outer wall of the telescopic rod.

[0017] The advantages of this invention are: by recording the entire process of the bottle's movement using a high-speed camera, it can capture the dynamic process of the bottle tipping over, including details such as jumping, tilting, and collision. Compared to existing technologies that can only determine the result of the bottle tipping over, this device can provide maintenance personnel with high-definition images that can be reviewed frame by frame, helping them to intuitively analyze the causes of bottle tipping over, such as abnormal conveyor belt speed, surface structural defects, and scratches from guardrails, thus significantly improving the accuracy and efficiency of fault diagnosis.

[0018] This device can also be flexibly deployed according to high-risk areas of the production line to achieve full coverage. Whether it is the empty bottle conveying section, the filling station, or the finished bottle transfer link, it can be quickly moved to the corresponding position for detection, significantly enhancing the versatility and adaptability of the detection device.

[0025] Please refer to Figures 1 to 3. This utility model provides a visual inspection-based bottle-inverting detection device for beverage production lines, which is installed at the bottle-inverting position 14 of the beverage production line. The detection device includes a movable support 1, a high-speed camera 2, a high-speed video camera 3, and a computer 4.

[0026] The high-speed camera 2, high-speed video camera 3, and computer 4 are all mounted on the mobile support 1;

[0027] Both the high-speed camera 2 and the high-speed video camera 3 are connected to the computer 4;

[0028] The high-speed camera 3 is used to capture and record the flow of bottles at the current position on the beverage production line. When a bottle tipping occurs on the beverage production line, maintenance personnel can use the computer 4 to play back the footage recorded by the high-speed camera 3 to determine the cause of the tipping.

[0029] When in use, this device is placed in areas of high incidence of bottle tipping based on feedback from production line workers. Because the device is portable, it is easy for maintenance personnel to move and deploy.

[0030] The high-speed camera 2 and the high-speed video camera 3 have a frame rate of 50 FPS or higher. The high-speed camera 2 continuously takes pictures of the bottles flowing through the beverage production line and transmits the collected data to the computer 4, which determines whether the bottles have tipped over. The computer 4 has a preset image recognition algorithm for identifying whether the bottles have tipped over. This image recognition algorithm is existing technology, such as the image recognition algorithm disclosed in patent application number CN202510025810.0.

[0031] After the bottle tipping occurs, computer 4 can record the current time. Based on this time, maintenance personnel can rewind the footage recorded by high-speed camera 3 to 10 seconds or more before the tipping occurred and start playing the video recorded by high-speed camera 3 frame by frame or in slow motion to observe the dynamic process of the tipping moment. This helps maintenance personnel quickly determine the factors that caused the tipping, improves the accuracy of fault diagnosis, and increases the speed of maintenance.

[0032] Specifically, the mobile support 1 includes a base plate 5, a telescopic rod 6, a computer mounting plate 7, and a camera mounting plate 8; the high-speed camera 2 and the high-speed video camera 3 are fixed on the camera mounting plate 8, and the computer 4 is mounted on the computer mounting plate 7.

[0033] The bottom of the base plate 5 is provided with movable wheels 9, the telescopic rod 6 is vertically provided on the top of the base plate 5, the top of the telescopic rod 6 is provided with a first connecting block 10, the first connecting block 10 is provided with a pin 11, the bottom of the camera fixing plate 8 is provided with a second connecting block 12, the second connecting block 12 is hinged to the pin 11, and the second connecting block 12 is also connected to a locking assembly for locking the second connecting block 12; after loosening the locking assembly, the second connecting block 12 can rotate around the pin 11 to adjust the pitch angle of the high-speed camera 2 and the high-speed video camera 3.

[0034] The computer placement board 7 is slidably connected to the telescopic rod 6.

[0035] Specifically, the telescopic rod 6 includes a fixed rod 61 and a sliding rod 62. The fixed rod 61 is fixedly connected to the base plate 5. The first connecting block 10 is disposed at the upper end of the sliding rod 62. The sliding rod 62 is sleeved in the inner cavity of the fixed rod 61 and slidably connected to the fixed rod 61. A set screw 63 is spirally connected to the outer wall of the fixed rod 61, and the set screw 63 passes through the fixed rod 61 and abuts against the outer wall of the sliding rod 62. The production line height may vary at different locations. When the production line height changes, the height of the high-speed camera 2 and the high-speed video camera 3 can be adjusted by adjusting the length of the telescopic rod 6 to adapt to the different heights of the beverage production line.

[0036] Specifically, the first connecting block 12 has an arc-shaped groove 101, and the locking device includes a locking screw 13, which passes through the arc-shaped groove 101 and is spirally connected to the second connecting block 12. After tightening the locking screw 13, the second connecting block 12 can be prevented from rotating around the pin 11.

[0037] Specifically, the computer placement board 7 includes a shelf 71, a connecting rod 72, and a ring 73. The shelf 71 is fixed to the upper end of the connecting rod 72, and the ring 73 is fixed to the lower end of the connecting rod 72. The ring 73 is slidably connected to the outer wall of the telescopic rod 6, and a fixing screw 15 is screwed onto the ring 73. The fixing screw passes through the ring 73 and abuts against the outer wall of the telescopic rod 6. Since different maintenance personnel have different heights, after loosening the fixing screw, the height of the computer placement board 7 can be adjusted by adjusting the relative position of the ring 73 on the telescopic rod 6, thus accommodating the height of different maintenance personnel.

[0038] High-speed camera 3 records the entire process of bottle movement, capturing the dynamic moment of bottle tipping, including details such as bouncing, tilting, and collisions. Compared to existing technologies that can only determine the result of bottle tipping, this device provides maintenance personnel with high-definition images that can be reviewed frame by frame, helping them to intuitively analyze the causes of bottle tipping, such as abnormal conveyor belt speed, surface defects, and scratches from guardrails, significantly improving the accuracy and efficiency of fault diagnosis.

[0039] The high-speed camera, high-speed video camera, and computer are all mounted on a mobile support, allowing the device to be flexibly deployed according to high-risk areas of the production line, achieving full coverage. Whether it's the empty bottle conveying section, the filling station, or the finished bottle transfer stage, it can be quickly moved to the corresponding position for detection, significantly enhancing the versatility and adaptability of the detection device.
