Description

TECHNICAL FIELD

[0001] The present application relates to the field of tobacco processing, in particular to a tobacco leaf processing feeding uniformization method and system, a terminal and a storage medium. BACKGROUND

[0002] Based on the special commercial attributes of tobacco itself, tobacco is a monopoly commodity in many countries, and has control requirements throughout the entire industry chain. From tobacco bales to tobacco strips, and from tobacco strips to cigarette products, the most stringent control measures need to be taken at each link. However, in the existing tobacco production process, especially in the raw material control mode of the warehouse mode, the control of the tobacco raw material processing process is often performed manually. One of the defects of this status quo is that manual control does not meet the requirements of strict control throughout the entire production process of tobacco to some extent, and the fault tolerance of manual control is low. Another defect is that the processing flow of raw materials, especially the feeding link in the threshing and redrying process, has the problem of uneven and unstable processing quality.

[0003] The uniformization processing of the threshing and redrying process is the core point for guaranteeing the quality of the raw material of cigarettes, and is also a key prerequisite for continuously improving the quality of cigarettes. Through the technology of uniformization processing, the uniformity and stability of the tobacco strips in the threshing and redrying process can be effectively improved, and the overall quality of the cigarette products can be improved. The production feeding link is the first link for raw tobacco to enter the production and processing workshop, and is an important link in the uniformization processing of raw tobacco. Whether the processing feeding of raw tobacco in the production feeding link is uniform has a crucial influence on the quality of finished cigarettes. Therefore, the uniformity control in the production feeding process is crucial for improving the quality of finished tobacco strips. SUMMARY

[0032] Before the present application is further described, the terms and nouns involved in the embodiments of the present application are explained, which are applicable to the following explanations:

[0033] The embodiments of the present application provide a tobacco leaf processing feeding uniformization method, a system of the tobacco leaf processing feeding uniformization method, and a storage medium and an electronic terminal for storing an executable program for implementing the tobacco leaf processing feeding uniformization method. As for the implementation of the tobacco leaf processing feeding uniformization method, the embodiments of the present application will explain an exemplary implementation scenario of the tobacco leaf processing feeding uniformization method.

[0034] As shown in FIG. 1, a flowchart of a tobacco leaf processing feeding uniformization method in the embodiments of the present application is shown. The tobacco leaf processing feeding uniformization method in the present embodiment mainly includes the following steps: Figure 1

[0035] Step S11: Obtain a tobacco formula, and generate a uniformity tobacco box shelving queue according to the tobacco formula; the tobacco formula includes the ideal weight proportion of each grade of tobacco leaf.

[0036] ​Specifically, the tobacco leaf formula refers to the ideal weight proportion of each grade of tobacco leaf for producing a batch of cigarettes. For example, for producing a certain type of cigarette, the cigarette needs to be composed of A-grade tobacco leaf, B-grade tobacco leaf and C-grade tobacco leaf, wherein the weight proportion of A-grade tobacco leaf is 20%, the weight proportion of B-grade tobacco leaf is 50%, and the weight proportion of C-grade tobacco leaf is 30%. In this example, “A-20%; B-50%; C-30%” is the tobacco leaf formula described in this embodiment. It should be noted that the tobacco leaf formula is set manually, and the operator can determine the tobacco leaf formula according to the type, composition, demand and other characteristics of the produced cigarette. After obtaining the tobacco leaf formula, a uniformity tobacco box stacking queue can be generated according to the tobacco leaf formula. Specifically, tobacco is usually carried in a tobacco box as a carrying unit to realize the flow and transportation on the production line. Since the stacking order of the tobacco box is controllable, the overall proportion of each grade of tobacco leaf can be controlled uniformly according to the pre-set tobacco leaf formula, combined with the maximum weight that each tobacco box can carry, the grade of tobacco carried in the tobacco box, and the stacking order of the tobacco box.

[0037] In some implementation processes of this embodiment, the step of generating a uniformity tobacco box stacking queue according to the tobacco leaf formula includes: calculating the number of tobacco boxes of each grade of tobacco in each tobacco cabinet according to the tobacco leaf formula; calculating the number of tobacco boxes of each grade of tobacco in each group in the tobacco cabinet based on the number of tobacco boxes of each grade of tobacco in each tobacco cabinet, to obtain the uniformity tobacco box stacking queue generated according to the tobacco leaf formula.

[0038] Specifically, this embodiment proposes a “cabinet formula + group formula” method for generating a uniformity tobacco box stacking queue. Here, a tobacco box sorting method of 5 tobacco boxes per group and 30 tobacco boxes per cabinet is taken as an example to generate a uniformity tobacco box stacking queue, wherein all the calculation results are rounded to integers according to the rounding principle:

[0039] The pre-set tobacco leaf formula: the proportion of A-grade tobacco leaf is a; the proportion of B-grade tobacco leaf is b; the proportion of C-grade tobacco leaf is c; and d is the sum of the proportions of the three grades of tobacco leaf (d=a+b+c).

[0040] First, the number of tobacco boxes of each grade of tobacco in each tobacco cabinet is calculated according to the tobacco leaf formula.

[0041] First cabinet: G1a=30×a / d; G1b=30×b / d; G1c=30-G1a-G1b;

[0042] Second cabinet: G2a=30×(a-G1a) / (d-30); G2b=30×(b-G1b) / (d-30); G2c=30-G2a-G2b;…

[0043] The nth-1 cabinet: G(n-1)a=30×[a-(G1a+G2a+…+G(n-2)a)] / [d-30×(n-2)];

[0044] G(n-1)b=30×[b-(G1b+G2b+…+G(n-2)b)] / [d-30×(n-2)]; G(n-1)c=30-G(n-1)a-G(n-1)b The nth cabinet: Gna=a-(G1a+G2a+…G(n-1)a); Gnb=b-(G1b+G2b+…G(n-1)b); Gnc=c-(G1c+G2c+…G(n-1)c);

[0045] Wherein, G1a represents the number of tobacco boxes of A grade tobacco leaves in the first cabinet; G1b represents the number of tobacco boxes of B grade tobacco leaves in the first cabinet; G1c represents the number of tobacco boxes of C grade tobacco leaves in the first cabinet, G1x represents the number of tobacco boxes of X grade tobacco leaves in the first cabinet, and so on.

[0046] G1a represents the number of tobacco boxes of A grade tobacco leaves in the first cabinet; G2a represents the number of tobacco boxes of A grade tobacco leaves in the second cabinet; G3a represents the number of tobacco boxes of A grade tobacco leaves in the third cabinet; Gna represents the number of tobacco boxes of A grade tobacco leaves in the nth cabinet, and so on.

[0047] Then, the number of tobacco boxes of each grade tobacco leaves in each group of tobacco in each tobacco cabinet is calculated based on the number of tobacco boxes of each grade tobacco leaves in each tobacco cabinet, and a uniformity tobacco box upper rack queue of the tobacco leaf formula is obtained.

[0048] The first cabinet first group: X1=5×G1a / 30; Y1=5×G1b / 30; Z1=5-X1-Y1;

[0049] The first cabinet second group: X2=5×(G1a-X1) / (30-5); Y2=5×(G1a-Y1) / (30-5); Z2=5-X2-Y2;

[0050] The first cabinet third group: X3=5×(G1a-X1-X2) / (30-5×2); Y3=5×(G1a-Y1-Y2) / (30-5×2); Z3=5-X3-Y3;

[0051] The first cabinet fourth group: X4=5×(G1a-X1-X2-X3) / (30-5×3); Y4=5×(G1a-Y1-Y2-Y3) / (30-5×3); Z3=5-X4-Y4;

[0052] The first cabinet group 5: X5=5x(G1a-X1-X2-X3-X4) / (30-5x4); Y5=5x(G1a-Y1-Y2-Y3-Y4) / (30-5x4); Z3=5-X5-Y5;

[0053] The first cabinet group 6: X6=5x(G1a-X1-X2-X3-X4-X5) / (30-5x5); Y5=5x(G1a-Y1-Y2-Y3-Y4-Y5) / (30-5x5); Z3=5-X6-Y6;

[0054] …

[0055] The number of groups of the nth cabinet = (Gna+Gnb+Gnc) / 5=d, d≤6.

[0056] The first group of the nth cabinet: Xn1=5xGna / (Gna+Gnb+Gnc), Yn1=5xGnb / (Gna+Gnb+Gnc); Zn1=5-Xn1-Yn1;…

[0057] The dth group of the nth cabinet: Xnd=Gna-Xn1-…-Xn(d-1); Ynd=Gnb-Yn1-…-Yn(d-1); Znd=Gnc-Zn1-…-Zn(d-1).

[0058] Wherein, X1 represents the number of A-grade tobacco boxes in the first group of the first cabinet; Y1 represents the number of B-grade tobacco boxes in the first group of the first cabinet; Z1 represents the number of C-grade tobacco boxes in the first group of the first cabinet; and the like.

[0059] X1 represents the number of A-grade tobacco boxes in the first group of the first cabinet; X2 represents the number of A-grade tobacco boxes in the second group of the first cabinet; X3 represents the number of A-grade tobacco boxes in the third group of the first cabinet; and the like.

[0060] For the convenience of understanding this step, the application further provides a calculation example:

[0061] As shown in Table 1, the proportion and weight of each grade of tobacco leaf under the B2FA raw material grade are shown.

[0062]

[0063] Table 1 Proportion and weight of each grade of tobacco leaf under B2FA raw material grade

[0064] Based on the proportion of A, B and C grade tobacco leaves as shown in Table 1, according to the generation method of the uniformity tobacco box upper rack queue of the cabinet and group matching, the calculation result as shown in Table 2 can be obtained. Figure 2A Figure 2B Then the B2FA raw material grade under the calculation result is shown as the feeding uniformity record schematic diagram. ​

[0065] As shown in FIG. 2, the queue uniformity based on the "cabinet + configuration" algorithm is good, and the proportion error of the tobacco of each grade can be controlled within ±2%. Figure 3A As shown in FIG. 3, the process uniformity control curve of the B2FA raw material grade is shown. Figure 3B

[0066] Step S12: According to the uniformity tobacco box stacking queue, each tobacco box to be stacked is sequentially stacked to the entrance of the box turning area.

[0067] Specifically, on the basis of having generated the uniformity tobacco box stacking queue, each tobacco box needs to be sequentially stacked to the entrance of the box turning area according to the order described in the uniformity tobacco box stacking queue. This step can be that an operator manually stacks each tobacco box to the entrance of the box turning area according to the order of the stacking queue, or it can be realized by a carrying device with the function of conveying tobacco boxes, such as an automatic track system, an intelligent mechanical arm, an intelligent hoisting system, etc.

[0068] Step S13: Obtain the identification information of the current stacked tobacco box, and transport the current stacked tobacco box to the feeding channel corresponding to the identification information.

[0069] Specifically, in order to more efficiently obtain the grade information of the tobacco carried in each tobacco box and / or the weight information of the tobacco carried in each tobacco box, an identification code with identification function is also provided at a designated position of each tobacco box. The information of the tobacco box that can be obtained according to the identification code includes but is not limited to the grade of the tobacco in the tobacco box (such as A grade, B grade, C grade, etc.), the type of the tobacco box (such as iron box, plastic box, cloth bag, etc.), the weight of the tobacco carried by the tobacco box (such as 180 kg, 250 kg, 330 kg, etc.). After obtaining the identification information of the tobacco box, the tobacco box can be transported to the feeding channel corresponding to the identification information according to the identification information. For example, if the tobacco of A grade corresponds to the first feeding channel and the tobacco of B grade corresponds to the second feeding channel, when the identification information of a certain tobacco box is obtained as the tobacco of A grade, the tobacco box is transported to the first feeding channel; similarly, when the identification information of a certain tobacco box is obtained as the tobacco of B grade, the tobacco box is transported to the second feeding channel.

[0070] In some implementation processes of the embodiment, the obtaining of the identification information of the current stacked tobacco box can also be the following steps: detecting whether the tobacco box reaches the identification area; when the tobacco box reaches the identification area, obtaining the identification information on the tobacco box.

[0071] ​Specifically, a step of detecting whether the tobacco box reaches the identification area can be added before the step of acquiring the identification information on the tobacco box. The step can be realized by a photoelectric switch. When the tobacco box reaches the identification area, the photoelectric switch detects the tobacco box signal at this time, and then the code scanning device is enabled to acquire the identification information on the tobacco box. The improved advantage is that the code scanning device is enabled when the photoelectric switch detects the tobacco box signal, and the code scanning device is kept off when the photoelectric switch fails to detect the tobacco box signal. In this way, the code scanning device does not have to be in an always-on state, which can effectively save power consumption and prolong the service life of the code scanning device. In addition, since the photoelectric switch first detects whether the tobacco box reaches the specified identification area, and then the code scanning device performs the identification operation, the situation of missing identification can be effectively avoided, thereby improving the accuracy of the acquired identification information data.

[0072] Step S14: calculating the actual weight proportion of each grade of tobacco leaf according to the identification information of all tobacco boxes in the past period, and adjusting the stacking queue according to the ideal weight proportion, so that the difference between the actual weight proportion and the ideal weight proportion does not exceed the error threshold.

[0073] In some implementation processes of the embodiment, the method of calculating the actual weight proportion of each grade of tobacco leaf according to the identification information of all tobacco boxes in the past period includes: obtaining the number of tobacco boxes that have entered the feeding channel, the weight of tobacco leaf corresponding to the tobacco boxes, and the grade information of tobacco leaf in the tobacco boxes according to the identification information of all tobacco boxes in the past period; and calculating the actual weight proportion of each grade of tobacco leaf according to the number of tobacco boxes that have entered the feeding channel, the weight of tobacco leaf corresponding to the tobacco boxes, and the grade information of tobacco leaf in the tobacco boxes.

[0074] Specifically, the code scanning device records the identification information recognized by it, and sends the recorded identification information to other data processing devices such as a background computer for data analysis and processing. Therefore, according to the acquired identification information (the data contained in the identification information includes but is not limited to the grade of tobacco leaf carried in the tobacco box, the weight data of the tobacco leaf carried in the tobacco box, the type of the tobacco box, etc.), the weight proportion of each grade of tobacco leaf can be calculated based on the historical acquired identification information. For example, in a certain scenario, the acquired identification information is as follows: 6 A-grade iron boxes, 4 B-grade iron boxes, 6 C-grade cloth bags, and the full load weight of the iron box is 250 kg and the full load weight of the cloth bag is 180 kg. Therefore, the total weight of the tobacco leaf is 3580 kg, the weight proportion of A-grade tobacco leaf is 41.9%, the weight proportion of B-grade tobacco leaf is 27.9%, and the weight proportion of C-grade tobacco leaf is 30.2%.

[0075] In some implementation processes of the embodiment, before the actual weight proportion of each grade of tobacco leaves is calculated according to the identification information of all tobacco boxes in the past period, the following step is further included: obtaining an overhead view of the current on-rack tobacco box before the tobacco box is flipped; judging whether the current on-rack tobacco box contains tobacco leaves according to the overhead view; and when the current on-rack tobacco box contains no tobacco leaves, the identification information of the current on-rack tobacco box is invalid identification information.

[0076] Specifically, the purpose of the step is to exclude the identification information of abnormal tobacco boxes and prevent the identification information of abnormal tobacco boxes from having a negative impact on the actual weight proportion of each grade of tobacco leaves calculated subsequently. Since the identification information of the tobacco boxes obtained historically is used as the basis for calculating the actual weight proportion, some abnormal conditions of the tobacco boxes may occur on the automatic production line, such as an empty tobacco box that contains no tobacco leaves is on-racked to the entrance of the flipping area, or the on-racked tobacco box overturns due to some reasons during movement in the feeding channel. These abnormal conditions of the tobacco boxes may cause the identification information of the tobacco boxes to be recognized and counted effectively, but actually no tobacco leaves or tobacco leaves meeting the quality enter the final quantitative feeding device, thereby causing errors in the calculation of the actual weight proportion. Based on this, after each on-racked tobacco box passes through the photographing area at the entrance of the flipping machine, the overhead view of the current on-racked tobacco box is captured by a camera, and whether the current on-racked tobacco box contains tobacco leaves is judged based on the grayscale value of the overhead view. If the current on-racked tobacco box is determined to be an empty tobacco box, the information is returned to the background computer, the identification information of the current on-racked tobacco box obtained previously is invalid information, and does not participate in the calculation of the actual weight proportion subsequently. Through the above improvement, whether each on-racked tobacco box contains an abnormal tobacco box can be effectively identified, and the influence of the abnormal tobacco box on the calculation of the actual weight proportion is excluded.

[0077] It should be noted that since the color distribution of the empty tobacco box is quite different from that of the tobacco box loaded with tobacco leaves, the algorithm for judging whether the current on-racked tobacco box contains tobacco leaves in the embodiment can be a color recognition algorithm. Taking the color recognition algorithm as an example, the overhead view of the tobacco box is converted from RGB to HSV color space through color space conversion, and then the create Trackbar() function is used to establish a sliding bar to perform threshold segmentation on each channel after color space conversion. The threshold segmentation result is statistically analyzed, the color of the image is judged, and the classification result is output. Based on this method, whether the current on-racked tobacco box is an empty tobacco box can be judged by the color recognition algorithm, and further processing is performed based on the judgment result.

[0078] In some embodiments of the present embodiment, the method of adjusting the shelving queue according to the ideal weight ratio to make the difference between the actual weight ratio and the ideal weight ratio not exceed the error threshold value comprises: obtaining the difference between the actual weight ratio and the ideal weight ratio; when the difference is equal to the error threshold value, regenerating the uniformity tobacco box shelving queue according to the difference; and shelving the tobacco boxes to the entrance of the box turning area in sequence according to the regenerated uniformity tobacco box shelving queue.

[0079] Specifically, after obtaining the actual weight ratio of the current tobacco leaves of each grade, the difference between the actual weight ratio and the ideal weight ratio of the tobacco leaves of each grade (the ideal weight ratio is the tobacco formula, which can be set by manual) is calculated, and the difference is the error between the actual weight ratio and the ideal weight ratio. The error value is compared with the error threshold value. When the error value reaches the error threshold value, it is judged that the actual weight ratio of the current tobacco leaves of each grade has a large deviation, and the shelving order of the tobacco boxes needs to be adjusted to make the error return to the acceptable error threshold value range. Therefore, when the error value reaches the error threshold value, the uniformity tobacco box shelving queue can be regenerated according to the actual error value. The original shelving queue is replaced by the regenerated uniformity tobacco box shelving queue, and the tobacco boxes are shelved to the entrance of the box turning area in sequence according to the regenerated uniformity tobacco box shelving queue. In this way, since the closed-loop feedback link is added in the process of the tobacco boxes, the error can be returned to the acceptable reasonable range by regenerating the shelving queue when the error reaches a certain threshold value.

[0080] In some embodiments of the present embodiment, when the difference is equal to the error threshold value, a warning information is generated; the warning information includes an audible and visual alarm, a warning information sent to a client, a warning information sent to a host, etc.

[0081] Specifically, the purpose of this step is to generate an audible and visual alarm information, or send a warning information to a client held by a staff, a customer, a maintenance personnel, or send a warning information to a host when the difference between the actual weight ratio and the ideal weight ratio reaches the error threshold value, indicating that the operation of the feeding system is in an abnormal state. In this way, the relevant personnel can know the operation state of the production line in time and make adjustments accordingly.

[0082] In some embodiments of the present embodiment, before the tobacco formula is obtained and the uniformity tobacco box shelving queue is generated according to the tobacco formula, the method further comprises: dividing the tobacco leaves into several grades according to the nicotine interval of the tobacco leaves; and placing the tobacco leaves in several tobacco boxes; wherein a single tobacco box is only used for placing tobacco leaves of the same grade; and setting an identification information for each tobacco box, the identification information including the grade of the tobacco leaves in the tobacco box.

[0083] Specifically, before obtaining the tobacco formula and generating the uniformity tobacco box stacking queue according to the tobacco formula, since the nicotine values of different tobaccos often have certain differences, a plurality of nicotine value intervals can be divided in advance, and the tobaccos are divided into a plurality of grades according to their nicotine values, for example, the nicotine value interval corresponding to the tobacco of grade A is P1; the nicotine value interval corresponding to the tobacco of grade B is P2; the nicotine value interval corresponding to the tobacco of grade C is P3, and so on. After completing the grade division of the incoming tobacco, the tobaccos are placed in a plurality of tobacco boxes. It should be noted that the tobacco grade in each tobacco box is consistent, and tobaccos of each grade are contained separately, and each tobacco box is required to be in a full load state. After completing the boxing of the tobaccos, an identification information is marked on each tobacco box, which can be a bar code as shown in Figure 4 , a two-dimensional code, or any other identification label. The information contained in the identification information includes but is not limited to the grade of the tobacco carried in the tobacco box, the weight data of the tobacco carried in the tobacco box, the type of the tobacco box (the type of the tobacco box can be used to identify the weight of the tobacco in the tobacco box, for example, the weight of the tobacco carried in the iron box is 250 kg, and the weight of the tobacco carried in the cloth bag is 180 kg), and any other identification information. As shown in the figure, 00000001 in the bar code represents the iron box-A grade, 00000002 represents the iron box-B grade, 00000003 represents the iron box-C grade, 00000004 represents the cloth bag-A grade, 00000005 represents the cloth bag-B grade, and 00000006 represents the cloth bag-C grade.

[0084] In some implementation processes of the embodiment, after the actual weight proportions of tobaccos of each grade are calculated according to the identification information of all tobacco boxes in the past period, the method further includes: generating a tobacco feeding curve graph according to the actual weight proportions of tobaccos of each grade; wherein the curve graph includes a curve of the actual weight proportions of tobaccos of each grade changing with time, and a straight line of the ideal weight proportions of tobaccos of each grade; and sending the tobacco feeding curve graph to a terminal device with display function.

[0085] Specifically, after obtaining the actual weight proportions of tobaccos of each grade, a tobacco feeding curve graph as shown in Figure 5 can also be generated in a visual manner. As shown in the figure, the curve graph includes the actual weight proportions of tobaccos of each grade changing with time (in the past period) and the ideal weight proportions of tobaccos of each grade. Figure 5The curve diagram is sent to a terminal device with display function, such as a monitoring device on the production line, a computing device of a staff, a mobile terminal of a customer, etc., so that relevant personnel can obtain the intuitive curve diagram at any time to understand the actual weight proportion of each grade of tobacco leaves on the tobacco leaf feeding production line at this time, and make timely adjustment or notify the line operator according to the information presented on the curve diagram.

[0086] In some implementation processes of the embodiment, the method further comprises: acquiring load data of the conveying device for conveying the empty tobacco boxes; and when the load data is equal to a preset load threshold, maintaining the conveying device at the entrance of the tipping area to run at a low speed until the load data is less than the load threshold.

[0087] Specifically, the technical problem to be solved by this step is how to prevent the tobacco boxes processed by the tipping machine from being blocked on the conveying device for conveying the empty tobacco boxes. To solve this problem, a gravity sensor is further arranged on the conveying device for conveying the empty tobacco boxes to monitor the quantity information of the empty tobacco boxes on the conveying device (the quantity information of the empty tobacco boxes can be obtained according to the gravity sensing data of the gravity sensor and based on the known weight of the empty tobacco boxes). A load threshold is preset, which is used to measure the risk of blocking of the conveying device for conveying the empty tobacco boxes. When the load data of the conveying device for conveying the empty tobacco boxes reaches the load threshold, it indicates that the quantity of the empty tobacco boxes on the conveying device is about to be full, and there is a high risk of blocking. At this time, the conveying device at the entrance of the tipping area is controlled by the background computer to run at a low speed, while the conveying device for conveying the empty tobacco boxes still maintains the original speed to convey the empty boxes out. After the empty boxes are continuously conveyed out for a period of time, the load data returns to a level below the load threshold, at which time the conveying device at the entrance of the tipping area is controlled to return to the original conveying speed, so that the whole tobacco box distribution module returns to be stable, and the problem of blocking of the empty tobacco boxes on the conveying device is effectively avoided.

[0095] As shown in Figure 7 A structural schematic diagram of a tobacco processing feeding uniformization system in the embodiments of the present application is shown. In the present embodiment, the tobacco processing feeding uniformization system 700 includes: a queue generation module 701 configured to obtain a tobacco formula, and generate a uniformity tobacco box shelving queue according to the tobacco formula; the tobacco formula includes an ideal weight ratio of each grade of tobacco; a tobacco box allocation module 702 configured to obtain identification information of the tobacco box, and transport the tobacco box to a feeding channel corresponding to the identification information; and a feedback adjustment module 703 configured to obtain an actual weight ratio of each grade of tobacco according to the obtained identification information, and make a difference between the actual weight ratio and the ideal weight ratio not more than an error threshold.

[0096] In some examples of the embodiment, the tobacco box distribution module comprises: a recognition device comprising a photoelectric switch and a code scanning device; the photoelectric switch is used to detect whether the tobacco box reaches a designated position, and the code scanning device is used to obtain identification information on the tobacco box; a conveying device is used to convey the tobacco box to a corresponding tobacco box turning machine; the tobacco box turning machine is used to pour tobacco leaves in the tobacco box into a quantitative feeding device; the quantitative feeding device is used to quantitatively discharge the tobacco leaves; and an electronic scale is used to weigh the tobacco leaves discharged by the quantitative feeding device.

[0097] Specifically, as shown in Figure 8 , a structure diagram of the tobacco box distribution module in an embodiment of the present application is shown.

[0098] The recognition device is arranged at the entrance of the tobacco box turning area, and the detection range of the recognition device is a detection area. The recognition device comprises a photoelectric switch and a code scanning device, the photoelectric switch is used to detect whether the tobacco box reaches a designated detection area, and the code scanning device is used to obtain identification information on the tobacco box. A plurality of branch conveying devices are arranged behind the detection area (for example, A, B and C grade channels as shown in Figure 8 , the number of conveying branches can be the same as the number of grades of the incoming tobacco leaves, or can be more than the number of grades of the incoming tobacco leaves, for example Figure 8 , when the weight proportion of B grade tobacco leaves in the tobacco formula is relatively high (for example, A grade is 25%, B grade is 50%, and C grade is 25%), in order to make the feeding proportion of each grade of tobacco leaves uniform, an additional conveying branch can be arranged as needed to convey B grade tobacco leaves with a higher weight proportion. In this case, if there are multiple feeding channels for conveying the same grade of tobacco leaves, the tobacco boxes carrying the same grade of tobacco leaves are sent into each feeding channel in turn and alternately. A tobacco box turning machine is arranged at the end of each conveying branch, and the tobacco box turning machine is used to pour out the tobacco leaves in the tobacco box. After the turning is completed, the empty tobacco box is conveyed to the outlet of the tobacco box turning area by the conveying device. A quantitative feeding device is arranged in the pouring direction of the tobacco box turning machine, and the quantitative feeding device quantitatively discharges the tobacco leaves according to the manually set feeding amount. An electronic scale is arranged at the discharge port of the quantitative feeding device, and is used to weigh the tobacco leaves discharged by the quantitative feeding device. The weighed tobacco leaves are conveyed to the next production link by the conveying device.

[0099] The operation process of the tobacco box distribution module is described in detail as follows: the tobacco boxes are sequentially placed on the shelves in the uniformity tobacco box shelving queue generated in advance to the entrance of the box turning area, and the tobacco boxes are moved to the detection area by the transmission device. When the photoelectric switch detects that the tobacco box reaches the detection area, the code scanning device identifies the label on the tobacco box to obtain the identification information of the tobacco box (the identification information of the tobacco box obtained by the code scanning device is uploaded to the feedback adjustment module for data analysis and processing). After obtaining the identification information of the tobacco box, the destination channel of the tobacco box can be obtained, for example, if the grade of the tobacco leaves in the tobacco box is A, the destination channel of the tobacco box is the A-grade channel, at this time, the transmission device is controlled by the PLC to transmit the tobacco box to each grade channel corresponding to the identification information of the tobacco box, and each grade channel is distributed in the form of a branch on the main line of the transmission device. When the tobacco box moves to the branch turning end along the transmission device, the box turning machine arranged at the branch turning end turns the tobacco box, so that the tobacco leaves in the tobacco box are guided out to the quantitative feeding device. At this time, the tobacco leaves and the tobacco box are separated and continue to move along different paths: after the tobacco leaves enter the quantitative feeding device, the quantitative feeding device quantitatively discharges the tobacco leaves to the electronic scale according to the preset feeding amount, and after the electronic scale completes the weighing of the tobacco leaves, the tobacco leaves enter the next generation link along the tobacco leaf outlet channel. After being processed by the box turning machine, the empty tobacco boxes on each branch return to the main line, and the transmission device transports the empty tobacco boxes on each branch back to the box turning area outlet through the main line to form a closed loop.
