[0061] Example 2
[0062] like Figures 1 to 7The illustrated visual weighing and leak detection integrated machine includes a frame 1, with a cover 2 on the top front side of the frame 1. The frame 1 is specifically formed by connecting an aluminum alloy frame to a cabinet door, supporting the components of the machine for visual inspection, weighing inspection, and leak detection. From right to left, the top of the frame 1 features a visual structure 3, a weighing structure 4, and a leak detection structure 5. The visual structure 3, installed on the top right side of the frame 1, is primarily used for detailed visual inspection of the bottles being transported below, accurately capturing surface defects, stains, or shape deviations, and identifying defective bottles as visually non-compliant (NG). Bottle; Weighing structure 4 is installed in the middle of frame 1 and is mainly used to accurately detect the weight of the bottles. This structure can quickly and accurately measure the weight of each bottle and compare it with the preset standard weight range to screen out products that do not meet the weight standard and judge bottles that do not meet the weight standard as weighing NG bottles; Side leakage structure 5 is installed on the top left side of frame 1 and is mainly used to test the sealing performance of the bottles. By sealing the bottles, it simulates the pressure problems encountered by the bottles in actual use and finally detects whether there is a leakage problem in the bottles, and judges bottles with side leakage as side leakage NG bottles.
[0063] The visual structure 3, weighing structure 4, and side leakage structure 5 all have a transmission component for transporting the bottle from right to left. During the transport, the bottle passes under the three structures in sequence and is inspected for visual, weight, and airtightness in sequence. Considering that the bottle is relatively light when it is not loaded with any contents, a visual escort rail 6 is also provided on the top rear side of the frame 1. The length of the visual escort rail 6 is the same as the length of the frame 1, so that it can protect the rear side of each bottle during transport. The difference is that the protection of the front side of the bottle during transport is set separately.
[0064] A first escort rail 310 is provided on the top front side of the frame 1, which is also located in front of the vision structure 3. The right side of the first escort rail 310 is flush with the right side of the frame 1. It is used to protect the front side of the bottle when it is transported to the bottom of the vision structure 3 for visual inspection. A second escort rail 410 is provided on the top middle side of the frame 1, which is also located in front of the weighing structure 4. It is used to protect the bottle when it is transported to the top of the weighing structure 4 for weight inspection. A third escort rail 510 is provided on the top left side of the frame 1, which is also located in front of the weighing structure 4. It is used to protect the bottle when it is transported to the bottom of the side leakage structure 5 for airtightness inspection.
[0065] The first escort rail 310 is flush with the right side of the frame 1 on the right side, and extends to the left side of the detection edge of the vision structure 3 on the left side. That is, after the bottle is detected by the vision structure 3, the front side is no longer limited by the first escort rail 310. Similarly, the left side of the second escort rail 410 also extends to the left side of the detection edge of the weighing structure 4, and the left side of the third escort rail 510 extends to the left side of the detection edge of the side leakage structure 5.
[0066] Furthermore, when a visual NG collection area 311 is formed between the first escort bar 310 and the second escort bar 410, after the bottle has been inspected by the visual structure 3, its front side is no longer restricted by the first escort bar 310. If the bottle is a visually OK bottle, it continues to move to the left for weighing inspection. If the bottle is an NG bottle, it is pushed forward in the visual NG collection area 311 to complete the collection of visually NG bottles. Similarly, a weighing NG collection area 411 is formed between the second escort bar 410 and the third escort bar 510. Visually OK bottles, after being inspected by the weighing structure... 4. After the inspection is completed, the visually OK and weighing OK bottles continue to move to the left, while the visually OK and weighing NG bottles are pushed forward in the weighing NG collection area 411, completing the collection of the weighing NG bottles; the side leakage NG collection area 511 is formed between the left side of the third escort rail 510 and the left edge of the frame 1. After the visually OK and weighing OK bottles are inspected by the side leakage structure 5, the visually OK, weighing OK, and side leakage OK bottles continue to move to the left, while the visually OK, weighing OK, and side leakage NG bottles are pushed forward in the side leakage NG collection area 511, completing the collection of the side leakage NG bottles.
[0067] Considering that the number of OK bottles with three properties detected in the same batch is not large, a bottle baffle 7 is also installed on the left side of the visual escort rail 6 to arrange and collect a certain number of OK bottles for use in the next process.
[0068] In summary: Bottles are placed sequentially on the right side of the cabinet and conveyed to the area below the visual structure 3 for inspection. Bottles with visual defects (NG) are pushed forward on the conveyor belt through the visual defect collection area 311, while bottles with visual acceptance (OK) continue to move to the left and are placed above the weighing structure 4 for inspection. Bottles with visual acceptance (OK) and weighing defects (NG) are pushed forward on the conveyor belt through the weighing defect collection area 411, while bottles with visual acceptance (OK) and weighing defects (OK) continue to move to the left and are placed below the side leakage structure 5 for inspection. Bottles with visual acceptance (OK), weighing defects (OK), and side leakage defects (NG) are pushed forward on the conveyor belt through the side leakage defect collection area 511, while bottles with visual acceptance (OK), weighing defects (OK), and side leakage defects (OK) are moved to the left and arranged behind the bottle baffle 7 for use in the next process.
[0069] Example 3
[0070] like Figures 1 to 7The illustrated visual weighing and side-leakage integrated machine has a visual structure 3 installed on the top right side of the frame 1. The visual structure 3 is used to perform detailed visual inspection of the bottles conveyed below, accurately capturing defects, stains, or shape deviations on the bottle surface, and identifying defective bottles as visually NG bottles; specifically configured as follows:
[0071] A first support frame 301 is symmetrically arranged on the front and back of the top right side of the frame 1. Visual conveying rollers 302 are symmetrically arranged between the first support frames 301. A visual conveying belt 303 is rotatably connected between the visual conveying rollers 302. When a visual conveying motor 307 is installed in the frame 1 and the output shaft of the visual conveying motor 307 is connected to the left visual conveying roller 302 through a first drive belt 308, the visual conveying motor 307 can be driven to drive the first drive belt 308 to rotate, which in turn drives the visual conveying roller 302 to drive the visual conveying belt 303 to rotate, thus driving the bottles on the visual conveying belt 303 to be transported to the left.
[0072] The specific visual inspection components are as follows: a first mounting bracket 304 is provided on the rear right side of the frame 1, a visual camera 305 is provided on the top front side of the first mounting bracket 304, and a visual light source 306 is provided on the outside of the visual camera 305. The visual camera 305 mainly captures image information of the bottle through its lens, such as size, shape, label, bottle cap, and possible defects, and converts the image information into digital signals and transmits them to the computer for processing. It accurately identifies whether the appearance of the bottle meets the production standards, and then removes defective products in real time, thereby improving product quality and production efficiency. The visual light source 306 provides the necessary lighting environment so that the bottle being inspected can be clearly photographed by the camera. The illumination type of the visual light source 306 can also be adjusted according to the characteristics of different bottles. For example, for transparent or semi-transparent bottles, a light source type that can penetrate the bottle can be selected to better detect internal defects of the bottle.
[0073] In addition, a visual sensor 313 is provided at the top of the frame 1, located to the left rear of the first conveyor rail 310. The visual sensor 313 is specifically located to the right of the visual camera 305. It is mainly used to capture images of the bottle and accurately determine the position of the bottle to be inspected on the visual conveyor belt 303, that is, to position the bottle. After the bottle completes the visual inspection, the inspection result is combined with the bottle positioning. When the NG bottle moves to the visual NG collection area 311, the visual test cylinder 312 installed on the visual conveyor rail 6 is operated once. The telescopic rod of the visual test cylinder 312 extends and pushes the NG bottle forward out of the visual conveyor belt 303. For ease of understanding, the visual test cylinder 312 is installed on the visual conveyor rail 6 and aligned with the position of the visual NG collection area 311.
[0074] Furthermore, a vision touch screen 12 PLC all-in-one machine 9 is hinged to the right side of the first mounting frame 304 via a robotic arm 8. The vision touch screen 12 PLC all-in-one machine 9 is mainly used to process the data collected by the vision camera 305, to identify the quality of the bottles, and to issue a drop instruction for NG bottles, that is, to command the vision test cylinder 312 to perform a telescopic movement to push the vision NG bottle forward out of the vision conveyor belt 303.
[0075] Example 4
[0076] like Figures 1 to 7 The illustrated visual weighing and leak-proof integrated machine has a weighing structure 4 installed in the middle of the frame 1. The weighing structure 4 is used to accurately detect the weight of the bottles, quickly and accurately measuring the weight of each bottle and comparing it with a preset standard weight range. Products that do not meet the weight standard are screened out, and bottles that do not meet the weight standard are judged as weighing NG bottles. The specific settings are as follows:
[0077] The inner wall of the frame 1 is provided with a weighing base plate 401. A pressure sensor 403 is installed on the top left side of the weighing base plate 401 via a protective seat 402. The protective seat 402 is divided into upper and lower layers and can protect the pressure sensor 403 placed inside. The top of the frame 1 is symmetrically provided with second support frames 405. Weighing rollers 406 are symmetrically rotated between the second support frames 405. A weighing conveyor belt 407 is connected between the weighing rollers 406. The weighing conveyor belt 407 is used to continue to transport the visual OK bottle to the left to cooperate with the weight detection. The top of the protective seat 402 is open and a fixing plate 404 is provided on the top of the protective seat 402 for connecting the pressure sensor 403. Data transmission between the force sensor 403 and the weighing conveyor belt 407: When the weighing conveyor belt 407 moves the bottle to the left and above the pressure sensor 403, the pressure sensor 403 can detect the bottle and provide high-precision load data. It will also compare the detected bottle weight data with a preset value. If it does not exceed the range, it is an OK bottle that is visually and in terms of weight. Otherwise, it is an NG bottle that is visually acceptable but in terms of weight. In this way, bottles that do not meet the weight requirements can be detected and rejected, avoiding problems such as unstable packaging, damage or leakage during transportation due to the bottle weight not meeting the requirements, thus ensuring product quality.
[0078] In addition, a weighing photoelectric eye 413 is installed at the top of the frame 1, located to the left rear of the second conveyor rail 410. The weighing photoelectric eye 413 is used to capture images of the bottle and accurately determine the position of the bottle to be tested on the visual conveyor belt 303, that is, to position the bottle. After the bottle completes the weight detection, the detection result is combined with the bottle positioning. When the NG bottle moves to the weighing NG collection area 411, the weighing test cylinder 412 installed on the visual conveyor rail 6 is operated once. The telescopic rod of the weighing test cylinder 412 extends and pushes the NG bottle forward out of the weighing conveyor belt 407. For ease of understanding, the weighing test cylinder 412 is installed on the visual conveyor rail 6 and aligned with the position of the weighing NG collection area 411.
[0079] Furthermore, a second mounting bracket 11 is provided on the rear side of the frame 1. The second mounting bracket 11 is equipped with a touch screen 12. The touch screen 12 has an operation box and a weighing display, buttons, indicator lights and other components on the front side. The weighing display is used to receive and process the detection data of the pressure sensor 403, detect the weight of the bottle, and send a command to the weighing test cylinder 412 to retract once, pushing the NG bottle out of the weighing conveyor belt 407.
[0080] Example 5
[0081] like Figures 1 to 7 The illustrated visual weighing side-leakage integrated machine has a side-leakage structure 5 on the top left side of the frame 1. The side-leakage structure 5 is mainly used to detect the sealing performance of bottles. By sealing the bottle, it simulates the pressure problems encountered by the bottle in actual use, and finally detects whether the bottle has leakage problems. Bottles with side leakage are judged as side-leakage NG bottles. The specific settings are as follows:
[0082] A third support frame 501 is symmetrically arranged on the front and back of the top left side of the frame 1. A side leakage conveying roller 502 is symmetrically rotated between the third support frames 501. A side leakage conveying belt 503 is rotatably connected between the side leakage conveying rollers 502. The side leakage conveying belt 503 is driven by a motor to rotate and is used to continue to transport the visual and weighing OK bottles to the left, in conjunction with the airtightness detection of the bottles.
[0083] The airtightness testing setup includes: a third mounting bracket 504 on the rear left side of the frame 1; a sliding bracket 505 on the top front side of the third mounting bracket 504; a sliding element 506 slidingly mounted on the sliding bracket 505; and an adjusting cylinder 507 mounted on the bottom front side of the sliding element 506. The bottom of the output shaft of the adjusting cylinder 507 is connected to the test head 508. This allows the sliding element 506 to slide on the sliding bracket 505, indirectly driving the adjusting cylinder 507 and the test head 508 to move up and down for adjustment, thus accommodating bottles of different heights and ensuring accurate measurement. The test head 508 can be accurately inserted into the bottle mouth for airtightness testing. When the bottle is moved below the test head 508, the extension rod of the cylinder 507 is extended to move the test head 508 downwards and insert it into the bottle mouth. Then, the bottle is filled with gas at a certain pressure, and the internal pressure of the bottle is checked for changes. If the bottle is airtight, the internal pressure will not change significantly. Otherwise, the gas will overflow in the direction of the leak point, and the internal pressure of the bottle will gradually decrease. Thus, the airtightness of the bottle can be tested simply by observing the change in the internal pressure of the bottle.
[0084] After the test is completed, the airtightness of the bottle is judged based on whether the pressure change exceeds the threshold. OK bottles continue to move to the left for stacking, while NG bottles are removed through the side leakage NG collection area 511.
[0085] A side leakage photoelectric sensor 513 is installed at the top of the frame 1, to the left and right of the third conveyor rail 510. The side leakage photoelectric sensor 513 is used to capture the image of the bottle and accurately determine the position of the bottle to be tested on the visual conveyor belt 303, that is, to position the bottle. After the bottle completes the side leakage detection, the detection result is combined with the bottle positioning. When the NG bottle moves to the side leakage NG collection area 511, the side leakage test cylinder 512 installed on the visual conveyor rail 6 is operated once. The telescopic rod of the side leakage test cylinder 512 extends and pushes the NG bottle forward out of the side leakage conveyor belt 503. For ease of understanding, the side leakage test cylinder 512 is installed on the visual conveyor rail 6 and aligned with the side leakage NG collection area 511.
[0086] The sliding component 506 specifically includes a guide sleeve and a lead screw. A test cylinder is mounted on the sliding frame 505 via the guide sleeve. The guide sleeve is a square frame, and the test cylinder is mounted on the bottom front side of the guide sleeve, so that the test head 508 mounted at the bottom of the test cylinder can be positioned directly above the bottle. At the same time, a lead screw is rotatably installed inside the sliding frame 505. The lead screw passes through the sliding frame 505 and is connected to a handle 13. That is, when the operator rotates the handle 13, the lead screw can be rotated inside the sliding frame 505. When the lead screw is screwed into the guide sleeve, the guide sleeve can be rotated by rotating the handle 13, thereby adjusting the height of the guide sleeve and ultimately adjusting the height of the test head 508 to adapt to the testing of bottles of different heights.
[0087] Example 6
[0088] like Figures 1 to 7 The visual weighing and side leakage integrated machine shown has an encoder 10 installed on the right side of the first support frame 301 at the rear. It is mainly used to collect the conveying data of the visual conveyor belt 303, the weighing conveyor belt 407 and the side leakage conveyor belt 503, convert the mechanical movement of the conveyor belt into electrical signals, detect the running status of the conveyor belt in real time, and optimize its performance to adapt to the best transmission speed for different bottle detection.
[0089] Furthermore, the machine contains multiple photocells to capture images of bottles at different detection stages and locate them. On the opposite side of each photocell, there is a reflector to work with it. Considering the varying lighting conditions in the detection environment, the reflector is provided. When the ambient light is weak or the light direction is not favorable for photocell detection, the reflector can be used to reflect the light onto the photosensitive surface of the photocell, thereby enhancing the sensitivity and accuracy of the photocell.
