Description

Technical Field

[0001] The utility model relates to the field of tobacco baking, in particular to a tobacco baking monitoring system. Background Art

[0002] Tobacco production generally includes several stages such as tobacco plant planting, tobacco leaf picking, tobacco leaf baking, and finished product processing. Among them, baking is an important part of the tobacco leaf production process, and the quality of tobacco leaf baking directly affects the grade of the subsequent tobacco. Baking is a process of evaporating the moisture in the tobacco leaves and changing the color from green to yellow. By controlling the temperature and ventilation in the drying room, the speed and degree of moisture evaporation of the tobacco leaves are ensured. When baking tobacco leaves, the tobacco baking staff must detect the baking state of the tobacco leaves in real time and reasonably adjust the baking mode according to the state of the tobacco leaves. This baking mode has a relatively high dependence on the operator and is easily affected by the experience and subjective factors of the operator, and the drying quality of the tobacco leaves cannot be guaranteed.

[0003] The "Intelligent Tobacco Baking Control System Device Based on Image Recognition and Tobacco Baking Room Environment Parameters" with the publication number of CN212809020U analyzes image recognition, the internal and external environment parameters of the tobacco baking room, fresh and dry ratio parameters, etc. The system calculates the air outlet temperature, exhaust volume, and intake volume of the tobacco baking equipment in real time and intelligently controls the tobacco baking equipment, exhaust fan, and fresh air fan to make the environment parameters in the tobacco baking room meet the baking stage of the tobacco leaves in real time until the tobacco leaves are baked. However, there are the following problems in this technical solution: Baking tobacco leaves is a batch operation. When there are abnormal bakes of tobacco leaves with a relatively low proportion during the baking process, the environment settings and modifications cannot be made for the abnormalities of this part of the tobacco leaves. Eventually, the abnormal tobacco leaves become waste materials under normal baking conditions, resulting in a waste of costs. Summary of the Invention

[0071] In this embodiment, the tobacco baking monitoring system includes a baking chamber 1 and related components disposed inside the baking chamber 1. Specifically, the baking chamber 1 has a structure with an internal cavity, and the baking chamber 1 is hermetically separated from the external environment to facilitate the adjustment of the temperature and humidity inside the baking chamber 1. For ease of understanding, the baking chamber 1 is divided into a waiting area 12 and a baking area 11. Among them, the waiting area 12 is the area for temporarily placing the tobacco leaves with abnormalities during the baking process, and the baking area 11 is the area for performing the normal baking process. Among them, the waiting area 12 and the baking area 11 may not be completely isolated, but have certain partition members to reduce the mutual influence of the adjustment of the temperature and humidity environment parameters between the waiting area 12 and the baking area 11. Further, this embodiment also sets a transition area 13 in the baking chamber 1. The transition area 13 is set at the junction of the waiting area 12 and the baking area 11. The setting of the transition area 13 facilitates the transition of the tobacco leaves from the baking area 11 to the waiting area 12, and can also further reduce the degree of air mixing between the waiting area 12 and the baking area 11, thereby reducing the mutual influence of the adjustment of the temperature and humidity environment parameters between the waiting area 12 and the baking area 11.

[0072] Specifically, a first conveying assembly 2 and a second conveying assembly 3 are provided inside the baking chamber 1. The first conveying assembly 2 corresponds to the baking area 11, and the second conveying assembly 3 corresponds to the waiting area 12. For the convenience of the transition and transportation of the tobacco leaves, a part of the first conveying assembly 2 is within the coverage of the transition area 13, and a part of the second conveying assembly 3 is within the coverage of the transition area 13. The first conveying assembly 2 includes a first conveying guide rail 21 and a first conveying guide rod 22. Among them, the first conveying guide rail 21 is laid in the baking area 11 in a first preset manner, such as Figure 1A laying method of the first conveying guide rail 21 is shown: the first conveying guide rail 21 includes three first channels laid in parallel and in the vertical direction, and two second channels laid in the horizontal direction, wherein a plurality of first conveying guide rods 22 may be arranged at intervals on each column of the first channels, the top ends of the plurality of first channels merge with a second channel, the ends of some of the second channels extend into the transition channel 42, and another second channel intersects with the bottom ends of the plurality of first channels, Figure 1 The arrows show the moving directions of the multiple first conveying guide rods 22. In normal use, the tobacco leaves are in the baking tray 5, and the baking tray 5 is set on the first conveying guide rods 22. The tobacco leaves are baked in the first channel under the transportation of the first conveying guide rods 22. When it is detected that there is an abnormality in the baking stage of the tobacco leaves, the first conveying guide rods 22 are adjusted in the first channel and the second channel in sequence to adjust the first conveying guide rod 22 where the abnormal tobacco leaves are located to the second channel at the top of the first channel, and move to the transition assembly 4 of the transition zone 13 under the transportation of the second channel, so as to realize the removal operation of the abnormal tobacco leaves in the baking zone 11.

[0073] The second conveying assembly 3 includes a second conveying guide rail 31 and a second conveying guide rod 32, wherein the second conveying guide rail 31 is laid in the baking area 11 according to a second preset manner, such as Figure 1 A laying method of the second conveying guide rail 31 is shown: the second conveying guide rail 31 is in a T-shaped structure in the baking chamber 1, wherein the downwardly extending portion is recorded as the third channel, and the horizontally extending portion is recorded as the fourth channel. The transition component 4 moves the baking tray 5 with abnormal tobacco leaves to the area where the third channel is located, and moves outward in the third channel to extend the second conveying guide rod 32. The second conveying guide rod 32 supports the tobacco tray in the transition component 4 and transports it to the fourth channel. The fourth channel is laid in the waiting area 12.

[0074] It should be noted that the first conveying guide rail 21 is matched with the first conveying guide rod 22, for example, when the first conveying guide rail 21 is a slide rail, the first conveying guide rod 22 is also a slider, or the first conveying guide rod 22 can be a structure including a slider, and when the first conveying guide rail 21 is a groove, the first conveying guide rod 22 can also be a structure including a roller. Similarly, the second conveying guide rail 31 is matched with the second conveying guide rod 32, for example, when the second conveying guide rail 31 is a slide rail, the second conveying guide rod 32 is also a slider, or the second conveying guide rod 32 can be a structure including a slider, and when the second conveying guide rail 31 is a groove, the second conveying guide rod 32 can also be a structure including a roller.

[0075] See also Figure 2 and Figure 3, in some embodiments, a first partition 15 is provided in the baking chamber 1.

The second conveying guide rail 31 includes a first conveying part and a second conveying part. The first conveying part is laid on the first side wall 151, and the second conveying part is laid on the second side wall 152.

[0076] It can be understood that when there are too many abnormal tobacco leaves, the storage of a batch of abnormal tobacco leaves can be realized by expanding the waiting area 12, such as Figure 2 and Figure 3 , in Figure 1 , another laying method of the second conveying guide rail 31 is shown on this basis: a first partition 15 is added in the baking chamber 1.

Under the guidance of the fourth channel on the side where the baking area 11 is located, the second conveying guide rod 32 and the baking tray 5 are turned and moved to the side away from the baking area 11, and a fifth channel arranged in parallel and extending in the vertical direction is added. Then, a plurality of second conveying guide rods 32 can be arranged in an array on the fifth channel like the first conveying guide rod 22.

[0077] Further, please refer to Figure 3 , in some embodiments, the baking chamber 1 is further provided with an observation area 14.

A part of the second conveying guide rail 31 extends from the waiting area 12 into the observation area 14, and the second conveying guide rod 32 can move from the waiting area 12 into the observation area 14. In this embodiment, the observation area 14 is added at the bottom of the baking chamber 1. It should be noted that the observation area 14 is not completely separated from the waiting area 12, but an observation window and a one-way embedded rubber glove for the user are provided on the side wall of the baking chamber 1 where the observation area 14 is located, so as to facilitate the user to grasp and inspect the tobacco leaves in the observation area 14. A part of the structure of the second conveying guide rail 31 extends into the observation area 14, so that the second conveying guide rod 32 can convey the baking tray 5 into the observation area 14 for the user to check.

[0078] In some alternative embodiments, a horizontally extending third conveying guide rail is laid in the observation area 14. One end of the third conveying guide rail can converge with the second channel in the first conveying guide rail 21, and the other end of the third conveying guide rail extends into the waste collection bucket. When the tobacco leaves in the observation area 14 are still abnormal after being baked with the adjustment of environmental factors in the waiting area 12, the user can input an operation instruction to move the baking tray 5 from the third conveying guide rail into the waste collection bucket by the second conveying rod 32. When the tobacco leaves in the observation area 14 have reached the normal baking degree, the baked tobacco leaves can be re-converged from the third conveying guide rail into the second channel and enter the production equipment corresponding to the next process.

[0079] Please refer to Figure 1 , in some embodiments, the first conveying guide rail 21 is arranged on the side wall of the baking chamber 1.

The upper surface of the second supporting portion is further provided with a second connecting groove, and the bottom surface of the baking tray 5 is provided with a second connecting protrusion, and the second connecting protrusion is adapted to the second connecting groove.

[0081] The first connecting portion can be understood as the area provided with a slider or a roller, and the first supporting portion can be understood as the area for supporting the baking tray 5. For the convenience of understanding, the specific structure of the first conveying rod 22 is distinguished according to functions into a first connecting portion and a first supporting portion. That is, the first connecting portion and the first supporting portion can be two parts of a whole, or two independent wholes. In this embodiment, no specific structure and shape of the first conveying rod 22 are limited. Similarly, the second connecting portion can be understood as the area provided with a slider or a roller, and the second supporting portion can be understood as the area for supporting the baking tray 5. For the convenience of understanding, the specific structure of the second conveying rod 32 is distinguished according to functions into a second connecting portion and a second supporting portion. That is, the second connecting portion and the second supporting portion can be two parts of a whole, or two independent wholes. In this embodiment, no specific structure and shape of the second conveying rod 32 are limited.

[0082] In this embodiment, the baking tray 5 is a tray containing tobacco leaves.

This method can unify the structures of the first supporting portion and the second supporting portion, avoiding the problem that the bottom surface of the baking tray 5 needs to be provided with the first connection protrusion and the second connection protrusion respectively. The bottom surface structure of the baking tray 5 can also be unified, so that it can be adapted to both the first connection groove and the second connection groove, simplifying the overall structure and reducing the complexity.

[0084] In some embodiments, the first conveying component 2 further includes a first driving unit, which is arranged on the side wall of the baking chamber 1 and is in transmission connection with the first connecting portion; the second conveying component 3 further includes a second driving unit, which is arranged on the side wall of the baking chamber 1 and is in transmission connection with the second connecting portion. The first driving unit and the second driving unit can be driving devices of the same type, and the specific model and category need to be selected according to the selection forms of the first conveying guide rod 22, the first conveying guide rail 21, the second conveying guide rod 32 and the second conveying guide rail 31. Taking the first conveying guide rod 22 as a structural member containing rollers and the first conveying guide rail 21 as a groove as an example, the first driving unit can be a micro servo motor that drives the rollers to rotate to drive the entire first conveying guide rod 22 to move along the first conveying guide rail 21; correspondingly, a steering component can also be provided so that the first conveying guide rod 22 can turn at the intersection of the first channel and the second channel, or two first driving units and multiple groups of rollers can be provided, where one group of rollers is connected to one first driving unit, and the moving direction of this group of rollers is the vertical direction, and the other group of rollers is connected to another first driving unit, and the moving direction of this group of rollers is the horizontal direction. By separately controlling the two first driving units, the turning of the first conveying guide rod 22 is realized; or, corresponding guide plates can also be provided on the first conveying guide rail 21 so that during the driving process of the first driving unit, the rollers can adaptively turn under the action of the guide plates. Similarly, the connection relationship between the second driving unit and the second conveying guide rod 32 and the second conveying guide rail 31 can be understood by referring to the connection relationship between the first driving unit and the first conveying guide rod 22 and the first conveying guide rail 21 described above, and will not be elaborated here.

[0085] Further, as Figure 1 shown, a transition component 4 is also provided in this embodiment. The transition component 4 includes a transition box body 41, a transition bracket 43 and a transition channel 42. The transition channel 42 is horizontally laid between the baking area 11 and the waiting area 12. The transition box body 41 can move relative to the transition channel 42. Among them, the transition box body 41 has a first inlet 411, a first outlet 412 and a second outlet 413. It should be noted here that the distinction between the inlet and the outlet is obtained according to the moving paths of the first conveying guide rod 22 and the second conveying guide rod 32, that is, in the transition box body 41, the openings where the first conveying guide rod 22 and the second conveying guide rod 32 enter the transition box body 41 are recorded as inlets, and the openings where the first conveying guide rod 22 and the second conveying guide rod 32 leave the transition box body 41 are recorded as outlets. Here, the first conveying guide rod 22 corresponds to the first inlet 411 and the first outlet 412. When in use, the second conveying guide rod 32 automatically protrudes into the transition box body 41 from the second conveying guide rail 31, so there is no need for an inlet, but there is a second outlet 413.

[0086] Specifically, the side of the transition box 41 that is in contact with the first side wall 151 of the baking chamber 1 is not provided with a sealing plate, and this method can realize the function that the transition box 41 can switch from the first conveying guide rail 21 to the second conveying guide rail 31 during the movement. The first inlet 411, the first outlet 412, and the second outlet 413 on the transition box 41 are arranged as shown in FIG. Figure 1 A transition bracket 43 is provided on the transition box 41 , and the transition bracket 43 moves with the transition box 41 . The transition bracket 43 is used to receive the baking tray 5 transported into the transition box 41 .

[0087] See also Figure 1 In some embodiments, the transition channel 42 has a second inlet 421, a third outlet 422 and a fourth outlet 423, the second inlet 421 coincides with the first inlet 411, the third outlet 422 coincides with the first outlet 412, the fourth outlet 423 coincides with the second outlet 413, and the transition bracket 43 is provided with a through slot 431, which is larger than the size of the first supporting portion and the second supporting portion; the transition assembly 4 also includes a third driving unit 44, which is disposed in the transition channel 42, and the third driving unit 44 is transmission-connected to the transition box 41 to drive the transition box 41 to move relative to the transition channel 42;

[0088] The transition box 41 can be placed in the first transition position and the second transition position. When the transition box 41 is placed in the first transition position, the third driving unit 44 drives the transition box 41 to extend, so that the first inlet 411 of the transition box 41 coincides with the second inlet 421, and the first outlet 412 coincides with the third outlet 422. The through slot 431 is placed on the conveying path of the first conveying guide rail 21. The first conveying guide rod 22 enters the transition box 41 from the baking area 11 through the first inlet 411, and passes through the transition bracket 43 from top to bottom through the through slot 431, so that the baking tray 5 is overlapped on the transition bracket 43, and the first conveying guide rod 2 2 moves out of the transition box 41 from the first outlet 412 and returns to the baking area 11. When the transition box 41 is placed in the second transition position, the third driving unit 44 drives the transition box 41 to extend and retract, so that the second outlet 413 of the transition box 41 coincides with the fourth outlet 423, the through slot 431 is placed on the conveying path of the second conveying guide rail 31, the second conveying guide rod 32 protrudes out of the second conveying guide rail 31 and is placed in the transition box 41, and passes through the transition bracket 43 from bottom to top through the through slot 431 to receive the baking tray 5 on the transition bracket 43, and moves out of the transition box 41 from the second outlet 413 and is placed in the waiting area 12.

[0089] In this embodiment, a second inlet 421, a third outlet 422, and a fourth outlet 423 are provided on the transition channel 42. The second inlet 421 coincides with the first inlet 411, the third outlet 422 coincides with the first outlet 412, and the fourth outlet 423 coincides with the second outlet 413. That is, when the transition box body 41 moves to the area where the first conveying guide rail 21 is located, the second inlet 421 coincides with the first inlet 411, and the third outlet 422 coincides with the first outlet 412. Then, the first conveying guide rod 22 can enter the transition box body 41 from the first inlet 411 and the second inlet 421, and then move out from the first outlet 412 and the third outlet 422. When the transition box body 41 moves to the area where the second conveying guide rail 31 is located, the fourth outlet 423 coincides with the second outlet 413. Then, after the second conveying guide rod 32 receives the baking tray 5, it can move out of the transition box body 41 from the fourth outlet 423 and the third outlet 422.

[0090] Specifically, a through groove 431 is further provided on the transition bracket 43. The through groove 431 can be penetrated by the first conveying guide rod 22 and the second conveying guide rod 32, but cannot be penetrated by the baking tray 5. Then, when the first conveying guide rod 22 drives the baking tray 5 to move to the transition bracket 43, the first conveying guide rod 22 moves out of the transition bracket 43 from the through groove 431, but the baking tray 5 will overlap on the transition bracket 43 under the action of inertia. Similarly, when the second conveying guide rod 32 penetrates the through groove 431 from bottom to top, the second connecting groove on the second conveying guide rod 32 is adapted to the second connecting protrusion on the baking tray 5 to lift the baking tray 5 upward so that it disengages from the transition bracket 43. The specific process can be understood in combination with the states of the first transition position and the second transition position of the transition box body 41. By providing the transition assembly 4 in this embodiment, the transition of the baking tray 5 between the waiting area 12 and the baking area 11 can be realized.

[0091] In some embodiments, a blower assembly is further included. The blower assembly includes a first blower and a second blower. The first blower is arranged in the baking area 11, and the second blower is arranged in the waiting area 12. The first blower and the second blower are respectively electrically connected to the control unit 100.

[0092] Furthermore, a sensor assembly 200, an image acquisition assembly 300, a temperature and humidity adjustment assembly 400, and a control unit 100 are also provided in this embodiment to realize the comprehensive monitoring of the tobacco leaves in the baking chamber 1.

[0093] Optionally, a terminal 500 and a server 600 may also be included. The control unit 100 is connected to the server 600, and the terminal 500 establishes a wireless communication connection with the server 600. The user can obtain the data situation in the current baking chamber 1 in real time on the terminal 500, and intervene in the control logic in the control unit 100 through the terminal 500 to realize the remote control of the baking chamber 1.

[0094] In some embodiments, the first sensor group 201 includes a first temperature sensor and a first humidity sensor. The first temperature sensor is disposed in the baking area 11 and is configured to collect the temperature of the baking area 11. The first temperature sensor is electrically connected to the control unit 100. The first humidity sensor is disposed in the baking area 11 and is configured to collect the humidity of the baking area 11. The first humidity sensor is electrically connected to the control unit 100. The second sensor group 202 includes a second temperature sensor and a second humidity sensor. The second temperature sensor is disposed in the waiting area 12 and is configured to collect the temperature of the waiting area 12. The second temperature sensor is electrically connected to the control unit 100. The second humidity sensor is disposed in the waiting area 12 and is configured to collect the humidity of the waiting area 12. The second humidity sensor is electrically connected to the control unit 100.

[0095] In this way, the environmental parameters of the waiting area 12 and the baking area 11 can be obtained respectively, which is convenient for subsequent adjustment of the environmental parameters of the tobacco leaves being baked.

[0096] In some embodiments, the number of the first image acquisition units 301 is multiple. The first image acquisition units 301 are configured to acquire the tobacco leaf images of multiple baking trays 5 in the baking area 11. The number of the second image acquisition units 302 is multiple. The second image acquisition units 302 are configured to acquire the tobacco leaf images of multiple baking trays 5 in the waiting area 12. In this way, image monitoring of the tobacco leaves on multiple baking trays 5 can be realized, and further combined with image recognition logic to evaluate and infer the baking degree of the tobacco leaves.

[0097] Taking the baking area 11 as an example, when the control unit 100 receives the image of the tobacco leaf, it will recognize the current baking degree of the tobacco leaf, obtain the temperature and humidity values required during real-time tobacco leaf baking, compare them with the temperature and humidity collected by the first temperature sensor and the first humidity sensor, obtain the difference between the real-time temperature and the required temperature, the difference between the real-time humidity and the required humidity, and control the first temperature and humidity adjustment group 401 to adjust the temperature and humidity in the baking area 11. The control logic of the waiting area 12 is similar to this.

[0098] The electronic components involved in the above embodiments can be directly obtained through the prior art, and specific expansion is not made in this embodiment.

[0099] In the above technical solution, a baking area 11, a waiting area 12 and a transition area 13 are demarcated in the baking chamber 1. A first conveying assembly 2 is arranged in the baking area 11 to realize the movement of the baking tray 5 between the baking area 11 and the transition area 13. A second conveying assembly 3 is arranged in the waiting area 12 to realize the movement of the baking tray 5 between the transition area 13 and the waiting area 12. Moreover, a first sensor group 201, a first image acquisition unit 301 and a first temperature and humidity adjustment group 401 are arranged in the baking area 11, and a second sensor group 202, a second image acquisition unit 302 and a second temperature and humidity adjustment group 402 are arranged in the waiting area 12. When there is abnormal tobacco, the baking tray 5 where the abnormal tobacco is located can be conveyed from the baking area 11 to the transition area 13, and then conveyed to the waiting area 12 through the transition area 13. The temperature and humidity configurations of the waiting area 12 and the baking area 11 can be different to realize the separate setting of the baking environment for the abnormal tobacco. This method can reduce the scrapping probability of the abnormal tobacco and save costs.
