Description

Technical Field

[0001] The present invention relates to the field of detection equipment, and in particular to an online stem component measuring instrument. Background Art

[0002] In recent years, intelligent factories have attracted much attention, and the intelligent transformation of the tobacco industry is also imminent. The current detection of stems after wind selection in tobacco factories is limited to the weight of the removed stems, and the weight of the stems is mainly used to judge the quality of a batch of tobacco wind selection. However, the removed stems are often mixed with tobacco, so the weight of the removed objects cannot actually reflect how many stems are actually removed from a batch of tobacco.

[0003] Chinese patent publication number CN113526176A, publication date October 22, 2021, the name of the invention is a rapid detection mechanism for tobacco structure, the application disclosure includes an equipment box, the equipment box is equipped with a feeding dispersion unit, a vibrating screen combination unit, a belt conveyor device, a controller and an image acquisition system, the feeding dispersion unit is arranged on the upper side of the equipment box, the top of the feeding dispersion unit has a feeding port, the bottom of the feeding dispersion unit has a discharge port, the vibrating screen combination unit is arranged below the feeding dispersion unit, the belt conveyor device is arranged below the vibrating screen combination unit, the image acquisition system is arranged above the discharge end of the belt conveyor device, and a storage box is provided below the discharge end of the belt conveyor device, the feeding dispersion unit, the vibrating screen combination unit, the belt conveyor device and the image acquisition system are all electrically connected to the controller.

[0051] The present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0052] Embodiment 1:

[0053] An online stem component measuring instrument, such as Figure 1-10 As shown, it includes various units with braking devices arranged inside and outside the machine body shell 100, which are a material taking unit 200, a vibration feeding unit 300, a detection unit 400, a material return unit 500 and an aggregate weighing unit 600 in the order of the stems passing through;

[0054] The material taking unit 200, the first conveyor belt 210 is connected to the reflux assembly 220, a feed port 227 is arranged on the top, and the discharge port 211 includes a first sensor 212 which can control the forward and reverse running of the first conveyor belt 210;

[0055] The vibrating loading unit 300, the discharge end of the vibrating assembly includes a spoiler 3121;

[0056] The detection unit 400 has a second switch 413 disposed on the second conveyor belt 410 and a visual detection component 430 disposed above;

[0057] The return unit 500, a second sensor 570 is disposed on the third conveyor belt 520;

[0058] The aggregate weighing unit 600 and the weighing hopper 640 are connected with at least two third sensors 641 capable of controlling the opening and closing of the aggregate weighing unit 600;

[0059] The second switch 413 controls the second conveyor belt 410 and the third conveyor belt 520 .

[0060] like Figure 1-3 As shown, a first support frame 110 is arranged inside the body shell 100, a display device 120 and a first observation window 130 are arranged in the front of the outside, an operation button 140 is arranged in the front side, and an alarm device 150 is arranged on the top.

[0061] In this solution, the first support frame 110 is used to support the detection unit 400 and the material return unit 500 .

[0062] The display device 120 will display the cumulative weight of each batch of stems and the silk content of the current batch of stems in real time. In this embodiment, the display device 120 is a touch display, which can be directly purchased from the manufacturer Shenzhen Jiaweishi Electronic Technology Co., Ltd., model JWS173-M200.

[0063] In this embodiment, the operation buttons 140 include main power, power, start / stop, reset, and emergency stop function buttons. Of course, the function buttons can be adjusted according to different needs before use.

[0064] In this solution, when a problem occurs in the equipment, the sensor in the unit with the problem will send a signal, and the alarm device 150 will give a reminder, so that the operator can immediately confirm the location of the problem on the display device 120 and perform maintenance. The alarm device 150 in this embodiment is a three-color alarm light, which can be purchased directly from the manufacturer Weima Kuaide Electromechanical Technology (Shanghai) Co., Ltd., model CST60. The working principles of the display device 120 and the alarm device 150 mentioned in this solution are prior art, and as technical common sense known to those skilled in the art, they will not be elaborated here.

[0065] like Figure 1 , Figure 2 and Figure 4 As shown, the material taking unit 200 includes a first conveyor belt 210 and a tension roller 213 wrapped in the middle thereof, one end of the first conveyor belt 210 is a reflux assembly 220, and the other end is provided with a discharge port 211, and the two sides and the bottom are connected to a second support frame 214 fixed on a first support base 215, and the discharge port 211 is provided with a first sensor 212 and is connected to a vibration feeding unit 300 below. The middle of the second support frame 214 is connected to a first motor 216.

[0066] like Figure 1 , Figure 2 and Figure 5 As shown, the reflux assembly 220 includes a reflux pipe 221 and a reflux plate 223. A blocking door 222 is provided at the inlet of the reflux pipe 221. The blocking door 222 is connected to the reflux plate 223 and a first reflux cylinder 224 and a second reflux cylinder 225 are installed on both sides. The bottom of the reflux plate 223 is connected to a third support frame 226, and the upper part is connected to a fourth support frame 2271 that fixes the feed port 227.

[0067] In this solution, the first reflux cylinder 224 and the second reflux cylinder 225 act on the blocking door 222 to control the opening and closing of the blocking door 222 .

[0068] The material taking unit 200 provided in this solution controls the first conveyor belt 210 to reverse through the monitoring of the first sensor, and conveys the excess stems to the return assembly 220, and conveys them away through the return pipe 221. The amount of stems is reasonably controlled to ensure that the stems in the vibration feeding unit 300 remain within the permitted range, and at the same time ensure that a clear image can be captured in the subsequent detection unit 400.

[0069] The first sensor 212 is mainly used to detect the height of the stalks in the vibration loading unit 300. When the material in the vibration loading unit 300 exceeds the limit height or the material at the discharge port 211 falls too much at once and exceeds the first sensor 212 installed at the discharge port 211, a signal will be triggered, and the first conveyor belt 210 will reverse to transport the stalks to the return assembly 220. The first sensor 212 is a height sensor in this embodiment. The height sensor is an existing technology and can be directly purchased from the manufacturer Omron (China) Co., Ltd. The model is E3S_CL2 limited reflective photoelectric sensor. As a technical common sense known to those skilled in the art, it will not be elaborated here.

[0070] It is worth mentioning that in actual use of this solution, the feed port 227 is generally connected to a stem stick storage bin, and the reflux pipe 211 can be connected to the stem stick storage bin in the early stage. After the excess stem sticks are transported to the reflux component 220, they are circulated into the stem stick storage bin through the reflux pipe 211, and the circulation of the stem sticks can be realized without manual labor. When the artificial intelligence completes the learning in the later stage, the amount of each delivery meets the requirements of each unit, and there is no need for reversal, and there is no phenomenon of excess stem sticks being transported to the reflux component 220.

[0071] In the structural setting of this solution, the tension roller 213 is used to adjust the progress of the first conveyor belt 210;

[0072] The material taking unit 200 further includes a first switch 217, which can independently control the operation of the first motor 216 during use. The first motor 216 in this embodiment is a single-phase speed regulating motor, which is a prior art motor and can be directly purchased from the manufacturer Xiamen Jingyan Automation Components Co., Ltd. The model is 90YT60GV22+90GF20H. As a technical common sense known to those skilled in the art, no further description is given here.

[0073] Specifically, the first switch 217 is manually turned on, the first motor 216 rotates forward, and the skewers fall from the feed port 227 onto the first conveyor belt 210;

[0074] Under normal circumstances, the stems in the vibration feeding unit 300 are within the permitted range, the first motor 216 drives the first conveyor belt 210 to continue to rotate forward, and the stems are transported to the tail and fall into the vibration feeding unit 300;

[0075] When an abnormal situation occurs, for example, the material in the vibration feeding unit 300 exceeds the limit or too much material falls out of the discharge port 211 instantly, the first sensor 212 installed at the discharge port 211 will trigger a signal, and the first conveyor belt 210 will rotate in the opposite direction to transport the stalks to the reflux component 220. The blocking door 222 will open, and the stalks will be discharged into the stalk storage bin through the reflux pipe 211.

[0076] like Figure 2 and Figure 6 As shown, the vibration feeding unit 300, the controller connected to the vibration component and the shock absorbing device 320 arranged at the bottom, the bottom of the shock absorbing device 320 is fixed on the bottom plate 330; the controller includes a first controller 3112 and a second controller 3122, the vibration component includes a circular vibration machine 311 controlled by the first controller 3112 and a direct vibration machine 312 controlled by the second controller 3122, the circular vibration machine 311 is provided with a vibration plate 3111, and the direct vibration machine 312 is provided with a spoiler 3121.

[0077] In the existing technical solutions, since the production line has a large amount of flexible air separation rejection material, tobacco shreds and stems overlap each other, and the rejection materials are directly photographed, it is impossible to accurately identify the morphological characteristics of stems and tobacco shreds.

[0078] The spoiler 3121 provided in the present solution can detect the rejected objects after flexible air selection online after shaking and flattening the stems, while ensuring that a clear image can be captured in the detection unit 400 later.

[0079] In this embodiment, the shock absorbing device 320 is an air spring vibration isolator. The air spring vibration isolator, the circular vibration machine 311 and the direct vibration machine 312 in this scheme are all existing technologies. The air spring vibration isolator can adopt Fabreeka PAL55-6. The circular vibration machine 311 and the direct vibration machine 312 can be purchased directly from the manufacturer Jiangsu Zhenqiang Machinery Technology Co., Ltd., which is a technical common sense known to technicians in this field and will not be elaborated here.

[0080] Specifically, the stem skewers fall into the vibration plate 3111 , and are evenly transported to the discharge port 211 of the vibration plate 3111 . The stem skewers fall into the spoiler 3121 below and are further dispersed, and then fall into the detection unit 400 after being dispersed.

[0081] The detection unit 400 includes a second conveyor belt 410 , a second motor 420 , and a visual detection component 430 .

[0082] like Figure 2 and Figure 7 As shown, the second conveyor belt 410 is connected to the fifth support frame 411 on both sides and fixed on the first support frame 110, the second motor 420 is connected to the first reduction device 412 and fixed on the fifth support frame 411, and the side of the fifth support frame 411 close to the vibration feeding unit 300 includes a second switch 413 and a first baffle 414.

[0083] like Figure 2 and Figure 8 As shown, the visual detection component 430 is arranged in a cover body 432 connected to the sixth support frame 431, including a visual detection device 433 and a light source device 434 arranged thereunder, and the bottom of the sixth support frame 431 is fixed on the first support frame 110.

[0084] The visual component provided in this solution can identify the proportion of tobacco in stems through visual inspection, detect and analyze the quality and composition of stems with artificial intelligence technology, and quickly and accurately evaluate the density, length, content and other key indicators of tobacco in stems by using advanced image processing and machine learning algorithms. This technology can help the tobacco industry better control and optimize product quality, improve production efficiency and consistency, and reduce manual errors and costs.

[0085] In the structural setting of this solution, the second switch 413 is a photoelectric switch, which electrically controls the second motor 420. When the stick touches the laser at the switch, the second motor 420 automatically turns on to control the second conveyor belt 410 to move forward. The setting of this structure realizes automatic control, while reducing costs and increasing efficiency, and reducing energy consumption. The second motor 420 is a prior art, and as a technical common sense known to those skilled in the art, it will not be elaborated here.

[0086] In the structural setting of this solution, a first baffle 414 is also provided on the fifth support frame 411. When the stalks first fall onto the second conveyor belt 410, they do not touch the laser of the second switch 413, that is, the second conveyor belt 410 is in a stopped state at this time, and the stalks are easy to slide off the conveyor belt. The setting of the baffle prevents the stalks from sliding off the second conveyor belt 410 during the continuous falling process, thereby avoiding the loss of the stalks.

[0087] The visual detection device 433 and the light source device 434 in the visual component identify the proportion of tobacco in the stem by visual detection. In this embodiment, the visual detection device 433 is a pre-scanning camera, the camera lens adopts a 35mm fixed focus lens, and the light source device 434 is a high-power analog light driver and a coaxial line scanning light source. The pre-scanning camera and the camera lens can be purchased directly from the manufacturer Hangzhou Hikvision Digital Technology Co., Ltd. The line scanning camera model is MV-CL086-91GC, and the camera lens model is MVL-LF3528M-F; the high-power analog light driver and the coaxial line scanning light source can be purchased directly from Shenzhen Ruishi Quancai Technology Co., Ltd. The model of the high-power analog light driver is P-HA-24W300-1 T, and the model of the coaxial line scanning light source is P-HCU-LSG-500-W. The pre-scanning camera and the high-power analog light driver are prior art, and the working principle is a technical common sense known to those skilled in the art, so it will not be elaborated here.

[0088] In the structural setting of the present scheme, the cover body 432 includes a front cover body and a rear cover body. The cover body 432 plays a dust-proof role for the visual detection component 430. At the same time, a through hole for installing the first observation window 130 is opened on the front cover body to facilitate the operator to observe the internal situation of the cover body 432.

[0089] Specifically, after the stem sticks fall onto the second conveyor belt 410, they touch the laser of the second switch 413, and the second conveyor belt 410 starts to run until the laser of the second switch 413 is no longer blocked by the stem sticks. During this process, the line scan camera detects and analyzes the stem sticks on the second conveyor belt 410 one by one, obtains the real-time silk content in the stem sticks, and displays it on the display device 120 in real time. The stem sticks fall onto the return material unit 500 after the camera takes a picture.

[0090] like Figure 1 , Figure 2 and Fig. 9 As shown, the return material unit 500 includes a driven roller 530 and an active roller 540 which are arranged at both ends of the second support base 510 and wrapped in the third conveyor belt 520. The active roller 540 is connected to the third motor 550 and the second reduction device 560, and the third motor 550 is electrically connected to the second sensor 570.

[0091] In the structural setting of this solution, the second sensor 570 is used to monitor the state of the third motor 550. Under normal circumstances, when the second switch 413 contacts the stalk, the third motor 550 drives the third conveyor belt 520 to rotate after receiving the signal of the second switch 413. When the second switch 413 does not contact the stalk, the third motor 550 and the second motor 420 stop working at the same time. If the third motor 550 does not start after the second switch 413 is triggered, the second sensor 570 next to the third motor 550 will sound an alarm.

[0092] In the structural setting of this solution, the second conveyor belt 410 forms a right angle with the third conveyor belt 520. When the stems fall from the second conveyor belt 410, some of the stems are likely to fall outside the device. The second baffle 511 and the third baffle 512 are arranged at the upper end of the second support base 510. The second baffle 511 is arranged at the feeding place of the return unit 500, and the top is higher than the second conveyor belt 410 and forms an angle with the third conveyor belt 520. The angle of the angle can meet the needs of conveying the stems and avoiding loss, and is not particularly limited;

[0093] The third baffle 512 is disposed at the discharge position of the return unit 500, and can prevent the loss of stems when the third conveyor belt 520 stops conveying.

[0094] like Figure 1 , Figure 2 and Fig.10 As shown, the aggregate weighing unit 600 includes a regulating valve 620 and a solenoid valve 630 arranged on the side of a weighing shell 610, and the weighing shell 610 includes a weighing hopper 640. The four corners of the top of the weighing hopper 640 are connected to a third sensor 641, and the bottom is connected to a fourth baffle 650 with first weighing cylinders 651 arranged on both sides. The fourth baffle 650 is arranged on a fifth baffle 660, and second weighing cylinders 661 are arranged on both sides of the fifth baffle 660.

[0095] In the structural setting of this solution, the third sensor 641 controls the first weighing cylinder 651 and the second weighing cylinder 661 to respectively drive the opening and closing of the fourth baffle 650 and the fifth baffle 660 by measuring the weight change of the four corners of the weighing hopper 640. Specifically, when the third sensor 641 does not detect the weight change within a certain period of time, the weight will be fed back to the display device 120 and recorded, and a signal will be sent to open the fourth baffle 650 and the fifth baffle 660.

[0096] It is worth mentioning that this solution uses artificial intelligence to learn the recorded data through the data feedback of the stem tag each time it passes through each unit, and continuously adjusts the amount of material released each time. After each material is released, the first conveyor belt 210 does not need to work in reverse, and it can also ensure that the visual inspection component 430 can capture a clear image.

[0097] In this embodiment, the first weighing cylinder 651 and the second weighing cylinder 661 as well as the first return cylinder 224 and the second return cylinder 225 mentioned above can all be purchased directly from the manufacturer AirTac (China) Co., Ltd., model MI 25x 175SU(0)+(DMSG-P-2). Cylinders are technical common sense well known to those skilled in the art and will not be elaborated here.

[0098] In this solution, the regulating valve 620 is used to control the air pressure of the total air intake path, and the solenoid valve 630 is used to control the air pressure of the total air intake path. In order to improve the efficiency of the production line, in this solution, the regulating valve 620 is a precision pressure regulating valve.

[0099] Specifically, the stem sticks fall into the weighing hopper 640 driven by the third conveyor belt 520. When the stem sticks in the weighing hopper 640 reach a specified weight, the front return unit 500 stops conveying the stem sticks, and the first weighing cylinder 651 and the second weighing cylinder 661 drive the fourth baffle 650 and the fifth baffle 660 to open. At the same time, the equipment records the weighing data, and the stem sticks fall and are discharged. Then the fourth baffle 650 and the fifth baffle 660 are closed, and the front return belt conveyor continues to convey the stem sticks to the weighing hopper 640.

[0100] Further explanation in combination with its usage mechanism:

[0101] The stem sticks fall onto the first conveyor belt 210 from the feed port 227, and fall into the vibrating plate 3111 driven by the first motor 216. The circular vibrator 311 vibrates to evenly transport the stem sticks to the spoiler 3121 of the vertical vibrator 312, and finally disperse and fall onto the second conveyor belt 410.
