Description

Technical Field

[0001] This disclosure relates to the field of tobacco blending and processing technology, and in particular to a method, apparatus and medium for removing auxiliary tobacco shreds. Background Technology

[0002] One of the main reasons why different brands of cigarettes produce different smoking experiences is the difference in the composition of the tobacco. Finished tobacco is primarily composed of main tobacco leaves and auxiliary tobacco leaves (expanded tobacco, stems, thin leaves, and recycled tobacco) mixed in a blending process according to production requirements. Depending on the grade of the finished tobacco, the brand, grade (different types of auxiliary tobacco leaves are classified into 1-5 different grades), and amount of auxiliary tobacco leaves added all vary. There is a general trend: higher-grade finished tobacco uses higher-grade tobacco leaves, while lower-grade finished tobacco uses lower-grade tobacco leaves.

[0003] In the blending process, each production line includes nine quantitative tobacco addition channels. Channels 1-3 are for main leaf tobacco, channels 4 and 5 are for sheet tobacco, channel 6 is for expanded tobacco, channels 7 and 8 are for stem tobacco, and channel 9 is for recycled tobacco. Each quantitative addition channel consists of a feeding hopper, a conveyor belt, a metering tube, and a belt scale. Semi-finished tobacco from the CT warehouse is turned into the feeding hopper by a turning machine, then evenly fed onto the conveyor belt and transported to the metering tube. After the flow rate is stabilized by the metering tube, it enters the belt scale. The belt scale evenly adds the auxiliary tobacco quantitatively to the tobacco mixing channel according to the main leaf tobacco flow rate and blending process ratio. The daily production plan for the blending process is based on batches. During normal production, according to the production process requirements, if the tobacco brands and grades in the metering channels of two adjacent batches are the same, the tobacco in the metering channels can continue to be used in subsequent production during batch changeover. If the auxiliary tobacco in subsequent batches is of the same brand but of a lower grade than the current auxiliary tobacco, the remaining auxiliary tobacco in the metering channel after the current batch ends can be used in subsequent production batches at a ratio of 1:6 (production process requirement). If the auxiliary tobacco in subsequent batches is of the same brand but of a higher grade than the current auxiliary tobacco, all remaining auxiliary tobacco in the metering channel must be removed from the production line after the current batch ends; that is, a material return operation is required for this batch. After the production of this batch is completed, the operator needs to confirm whether the brand and grade of the remaining materials in this batch can be used for subsequent production tasks according to the process requirements. If the grade or weight of the remaining tobacco does not meet the specified requirements, the remaining materials need to be returned. If the material grade meets the requirements, the remaining amount of material in the metering channel must be manually calculated, and then the ratio of this remaining amount to the required amount of this material in subsequent batches is used to determine whether a material return is necessary. Since each feed bin can hold more than 300-400KG of tobacco shreds, while each tobacco box can only hold 90-120KG of tobacco shreds, without human intervention in the operation of the box turning machine, it takes 1-3 empty tobacco boxes to remove all the tobacco shreds from the feed bins. The entire unloading process takes 10-30 minutes.

[0004] In summary, during batch changes in the blending process, local operators must participate in confirming and calculating the usage of the batch of materials and frequently perform material return operations based on production conditions. Furthermore, the inability to accurately calculate material weight results in a large quantity of tobacco shreds needing to be removed from production, extending the material return time. This prolonged material return operation not only affects product production efficiency but also increases the likelihood of tobacco shreds breaking. Summary of the Invention

[0005] This disclosure proposes a method, apparatus, and medium for removing auxiliary tobacco shreds to solve the aforementioned technical problems.

[0006] According to a first aspect of this disclosure, a method for returning auxiliary tobacco shreds is provided, comprising: obtaining the total weight X1 of auxiliary tobacco shreds turned into the production line in the current batch, the total weight X2 of tobacco shreds flowing through the belt scale in the current batch, and the remaining amount X' of auxiliary tobacco shreds in the quantitative channel in the previous batch; calculating the remaining weight X of tobacco shreds in the quantitative channel based on X1, X2, and X'; obtaining current batch information and next batch information and comparing the current batch information with the next batch information to obtain a comparison result, wherein the current batch information and the next batch information each correspond to the grade of auxiliary tobacco shreds in the current batch and the grade of auxiliary tobacco shreds in the next batch, respectively; if the grade of auxiliary tobacco shreds in the next batch is higher than the grade of auxiliary tobacco shreds in the current batch, calculating the remaining required amount Z based on the total amount of tobacco shreds G required in the current batch and X2; determining whether X > Z, and if so, stopping the turning of the batch and performing a return operation after the current batch production is completed.

[0007] In some embodiments, if the grade of the next batch of auxiliary tobacco is lower than that of the current batch of auxiliary tobacco, the required amount of tobacco Y for the next batch is calculated, and the ratio of XZ to Y is calculated. When the ratio is greater than 0 and less than a threshold, the turning of the box is stopped, and no material return operation is performed after the current batch of production is completed.

[0008] In some embodiments, if the grade of the next batch of auxiliary tobacco is equal to the grade of the current batch of auxiliary tobacco, the process continues to turn over the boxes, and no material return operation is performed after the current batch of production is completed.

[0009] According to a second aspect of this disclosure, a device for unloading auxiliary tobacco shreds is provided, comprising: an acquisition module for acquiring the total weight X1 of auxiliary tobacco shreds turned into the production line in the current batch, the total weight X2 of tobacco shreds flowing through the belt scale in the current batch, and the remaining amount X' of auxiliary tobacco shreds in the quantitative channel in the previous batch; a first calculation module for calculating the remaining weight X of tobacco shreds in the quantitative channel based on X1, X2, and X'; a comparison module for acquiring current batch information and next batch information and comparing the current batch information with the next batch information to obtain a comparison result, wherein the current batch information and the next batch information each correspond to the grade of auxiliary tobacco shreds in the current batch and the grade of auxiliary tobacco shreds in the next batch, respectively; a second calculation module for calculating the remaining required amount Z based on the total amount G of tobacco shreds required in the current batch and X2 if the grade of auxiliary tobacco shreds in the next batch is higher than the grade of auxiliary tobacco shreds in the current batch; and an unloading operation module for determining whether X > Z, and if so, stopping the turning of the batch and performing an unloading operation after the current batch production is completed.

[0010] According to a third aspect of this disclosure, an auxiliary tobacco strip removal device is provided, comprising: a memory; and a processor coupled to the memory, the processor being configured to execute the auxiliary tobacco strip removal method as described above based on instructions stored in the memory.

[0011] According to a fourth aspect of this disclosure, a computer-storeable medium is provided having computer program instructions stored thereon, which, when executed by a processor, implement the auxiliary tobacco strip removal method as described above.

[0012] By adopting the above technical solution, the beneficial technical effects that the embodiments of this disclosure can achieve are as follows: the blending process can automatically determine whether the material grade in the quantitative pass can be used in the next batch of production. If the material grade meets the reuse conditions, the box-turning machine system can control the remaining weight of tobacco in the quantitative pass according to the output of the next batch to ensure that the material in the pass can be successfully reused in the next production batch, and there is no need to return the material. If the material grade does not meet the reuse conditions, the box-turning machine system can still ensure that the remaining material in the quantitative pass only needs one empty tobacco box by controlling the number of boxes turned. When returning the material, there is no need to wait for a second empty box, which reduces the return time, improves production continuity, and reduces the tobacco breakage rate.

[0020] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0021] At the same time, it should be understood that, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn according to actual scale.

[0022] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0023] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0024] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0026] Currently, during batch changes in the blending process, local operators are required to confirm and calculate the usage of the batch of materials and frequently perform material return operations based on production conditions. Furthermore, the inability to accurately calculate material weight results in a large quantity of tobacco shreds needing to be removed from production, extending the material return time. This prolonged material return process not only affects production efficiency but also increases the likelihood of tobacco shreds breaking.

[0027] In view of this, this disclosure proposes a method, device and medium for returning auxiliary tobacco shreds. The blending process can automatically determine whether the material grade in the quantitative pass can be used in the next batch of production. If the material grade meets the reuse conditions, the box-turning machine system can control the remaining weight of tobacco shreds in the quantitative pass according to the output of the next batch to ensure that the material in this pass can be successfully reused in the next production batch, and there is no need to return the material. If the material grade does not meet the reuse conditions, the box-turning machine system can still ensure that the remaining material in the quantitative pass only needs one empty tobacco box by controlling the number of boxes turned. There is no need to wait for a second empty box when returning the material, which reduces the return time, improves production continuity and reduces the tobacco shred breakage rate.

[0028] Figure 1 This is one of the flowcharts illustrating a method for removing auxiliary tobacco shreds according to some embodiments of the present disclosure. For example... Figure 1As shown, the method for removing auxiliary tobacco shreds includes steps 110 to 160.

[0029] In step 110, obtain the total weight X1 of the auxiliary tobacco shreds that are turned into the production line in the current batch, the total weight X2 of the tobacco shreds that flow through the belt scale in the current batch, and the remaining amount X' of the auxiliary tobacco shreds in the quantitative channel in the previous batch.

[0030] In step 120, the weight X of the remaining tobacco in the quantitative channel is calculated based on X1, X2, and X'.

[0031] In step 130, the current batch information and the next batch information are obtained and compared with the next batch information to obtain a comparison result. The current batch information and the next batch information each correspond to the grade of the auxiliary tobacco shreds in the current batch and the grade of the auxiliary tobacco shreds in the next batch, respectively.

[0032] In step 140, if the comparison result shows that the grade of the next batch of auxiliary tobacco is higher than that of the current batch of auxiliary tobacco, the remaining required amount Z is calculated based on the total amount of tobacco required in the current batch G and X2.

[0033] In step 150, determine whether X > Z. If so, stop turning the boxes and perform a material return operation after the current batch of production is completed.

[0034] In some embodiments, if the comparison result is that the grade of the auxiliary tobacco shreds in the next batch is lower than that in the current batch, the required amount of tobacco shreds Y for the next batch is calculated, and the ratio of XZ to Y is calculated. When the ratio is greater than 0 and less than a threshold, the turning of the boxes is stopped, and no material return operation is performed after the current batch of production is completed.

[0035] In some embodiments, if the comparison result shows that the grade of the next batch of auxiliary tobacco is equal to the grade of the current batch of auxiliary tobacco, the process continues to turn over the boxes, and no material return operation is performed after the current batch of production is completed.

[0036] like Figure 2 As shown, in some embodiments, after production begins, the turning machine system turns the tobacco into the quantitative channel feeding bin while simultaneously recording and accumulating the weight of the turned tobacco to obtain the total weight X1 of the tobacco entering the production line in each pass of that batch. Simultaneously, as production progresses, the belt scale at the end of the quantitative channel records and calculates the total weight X2 of the tobacco flowing through it in that batch, and transmits X2 to the turning machine system via a network communication system. The turning machine system then calculates the remaining weight X of the tobacco in each quantitative channel based on X1, X2, and the remaining amount X' in the quantitative channel from the previous batch. Wherein:

[0037] X = X1 - X2 + X';

[0038] Before the current batch of production ends, the box-turning machine system will compare the batch information of the next work order temporarily stored in the work order cache with the current work order. The comparison result will be divided into the following three situations:

[0039] In the first scenario, the grade of tobacco shreds in all quantitative channels of the next batch is the same as the current material grade. The turning machine operates continuously, and no material needs to be returned after the current batch is completed. The remaining auxiliary tobacco shreds in this quantitative channel continue to be used in subsequent production activities.

[0040] In the second scenario, the grade of auxiliary tobacco shreds in the quantitative channel of a production batch is higher than that of the current batch. The box-turning machine system will calculate the remaining required amount Z based on the total amount G of tobacco shreds needed for that quantitative channel in this batch and the amount of tobacco shreds already used x2, i.e.:

[0041] Z = G - X², and when X > Z, the box-turning machine stops turning the boxes. After this batch of production is completed, the quantitative channel needs to be unloaded, and the remaining material can be loaded into an empty cigarette box.

[0042] In the third scenario, the grade of the auxiliary tobacco shreds in the quantitative channel of the next production batch is lower than that of the current batch. The box-turning machine system first calculates the required amount Y of tobacco shreds for that quantitative channel in the next batch, and controls the box-turning machine to operate by using the ratio of the remaining amount XZ of tobacco shreds for that quantitative channel after the current batch ends to Y. When this ratio is greater than 0 and less than 1 / 6 (threshold), the box-turning machine stops turning the boxes, and the remaining tobacco shreds in that quantitative channel do not need to be returned after production ends and can continue to be used for the production of the next batch.

[0043] In the auxiliary tobacco shred return method of this disclosure embodiment, the blending process can automatically determine whether the material grade in the quantitative pass can be used in the next batch of production. If the material grade meets the reuse conditions, the box turning machine system can control the remaining weight of tobacco shreds in the quantitative pass according to the output of the next batch, so as to ensure that the material in the pass can be successfully reused in the next production batch, and there is no need to return the material. If the material grade does not meet the reuse conditions, the box turning machine system can still ensure that the remaining material in the quantitative pass only needs one empty tobacco box by controlling the number of boxes turned, and there is no need to wait for a second empty box when returning the material, which reduces the return time, improves production continuity, and reduces the tobacco shred breakage rate.

[0044] Figure 3 This is a block diagram illustrating a device for unloading auxiliary tobacco shreds according to some embodiments of the present disclosure. Figure 3 As shown, the auxiliary tobacco shred unloading device 300 includes an acquisition module 310, a first calculation module 320, a comparison module 330, a second calculation module 340, and an unloading operation module 350.

[0045] The acquisition module 310 is configured to acquire the total weight X1 of the auxiliary tobacco shreds that are turned into the production line in the current batch, the total weight X2 of the tobacco shreds that flow through the belt scale in the current batch, and the remaining amount X' of the auxiliary tobacco shreds in the quantitative channel in the previous batch.

[0046] The first calculation module 320 is configured to calculate the weight X of the remaining tobacco in the quantitative channel based on X1, X2, and X'.

[0047] The comparison module 330 is configured to acquire the current batch information and the next batch information and compare the current batch information with the next batch information to obtain a comparison result. The current batch information and the next batch information each correspond to the grade of the current batch of auxiliary tobacco and the grade of the next batch of auxiliary tobacco, respectively.

[0048] The second calculation module 340 is configured to calculate the remaining required amount Z based on the total amount of tobacco required in the current batch and X2 if the comparison result is that the grade of the next batch of auxiliary tobacco is higher than the grade of the current batch of auxiliary tobacco.

[0049] The material return operation module 350 is configured to determine whether X > Z. If so, it stops turning over the boxes and performs the material return operation after the current batch of production is completed.

[0050] In the apparatus of this embodiment, the blending process can automatically determine whether the material grade in the quantitative pass can be used in the next batch of production. If the material grade meets the reuse conditions, the box-turning machine system can control the remaining weight of tobacco in the quantitative pass according to the production of the next batch to ensure that the material in the pass can be successfully reused in the next production batch, and there is no need to return the material. If the material grade does not meet the reuse conditions, the box-turning machine system can still ensure that the remaining material in the quantitative pass only needs one empty tobacco box by controlling the number of boxes turned. When returning the material, there is no need to wait for a second empty box, which reduces the return time, improves production continuity, and reduces the tobacco breakage rate.
