Background
The method constructs a whole cigarette product life cycle tracing system covering various links such as industry, business, zero, elimination and the like, is an internal requirement of the tobacco industry for improving the quality of cigarette products, improving the market supervision level and realizing high-quality development by insights of consumption trend change, and is an external requirement of China for fulfilling the tobacco control framework convention in the world. In order to standardize cigarette production and circulation management in the tobacco industry of China, a cigarette production operation decision system is established, bar code labels are pasted on cigarette boxes produced by cigarette industry enterprises, and code scanning is carried out in the ex-warehouse link of the industrial enterprises and the in-warehouse link of the commercial enterprises, so that the tracing of product allocation among the industrial enterprises and the commercial enterprises is realized. The smallest unit traced back is the smoke box, each containing 50 cigarette sticks. For industrial enterprises, the bar code on the smoke box can be used as an identifier for tracing the smoke box outwards and can be used as an identifier for batch production management inwards, and the identifier comprises production information such as production batch, production time, production materials and the like. When a cigarette business enterprise distributes cigarettes to retail customers, the cigarette boxes need to be unpacked and sorted, and the cigarettes are sent to the retail customers in the unit of a carton. Because the existing barrel and cigarette box are not associated, after the cigarette barrel is delivered to a retail shop, the cigarette box corresponding to the barrel and the production information of the cigarette box cannot be traced upwards, the market circulation information of the cigarette barrel cannot be traced downwards, and the tracing information chain is broken.
In recent years, two-dimensional codes are widely applied to cigarette product packaging, and in order to improve the fineness of tracking and tracing of cigarette products, tobacco enterprises begin to try to establish an association relationship between a cigarette carton and a cigarette box by using a two-dimensional code of the cigarette carton. In the prior art, a code reader is arranged on a strip box conveying belt at the front end of a strip box filling machine, and meanwhile, the code reader is arranged at the rear end of a strip code labeling machine at the rear end of the filling machine, and every time 50 strip box two-dimensional codes are read to be associated with one cigarette box bar code.
The prior art has the following defects:
1. in the prior art, the two-dimensional codes of the carton and the bar codes of the cigarette box are related according to the relation sequence of 50 to 1, the recognition rate of the code reader is required to ensure that the two-dimensional codes of a certain number of cigarettes are completely correct, otherwise, the related sequence of the whole queue is influenced once the two-dimensional codes of the cigarettes are not recognized. Sequence errors can be accumulated continuously, and the accumulation errors cannot be controlled under the condition that the box filling machine works for a long time. Because the actual production is influenced by various environmental and manual operation factors, the reading rate is difficult to reach one hundred percent, and the application of the prior art is very limited.
2. The prior art can not judge whether the packaged smoke box is correctly associated, the smoke box needs to be subjected to spot check frequently, if the association error is found, the association sequence of the carton and the smoke box is readjusted, the spot check process wastes time and labor, and the production efficiency is greatly influenced.
The prior art requires that when a box filling machine is started, a strip box cannot be left inside the box filling machine, otherwise, the left strip box changes the association sequence, so that the associated data is wrong. Because empty and persist the tobacco rod and need open the case packer, take out one by one with manual mode, greatly increased operation workman's work load.

s46, repeating S41-S45, and carrying out subsequent association; when the last cigarette pack is produced, only one datum D (1) is left in the positioning identification code data queue, and the first N data in the strip pack identification code data queue are correlated with the first cigarette pack identification code datum X (1), so that the data correlation of all the strip packs and the cigarette packs 6 is finally completed.
In the actual production process, the abnormal conditions comprise two categories of human reasons and equipment reasons. The artificial reason mainly means that the identification code of a carton or the identification code of a cigarette box belonging to the same cigarette box does not accord with the real object due to manual operation. The main index code identification failure of the equipment reason comprises the following conditions: the failure of the strip box code reader 3 to recognize the identification code, the failure of the positioning code reader 5 to recognize the identification code, the failure of the smoke box code reader 9 to recognize the identification code, etc.
For human reasons, fig. 4-7 show 4 cases where manual operation causes the actual carton loaded into the carton 6 to disagree with the data in the alignment of the identification code of the carton. In the embodiments illustrated in fig. 4-7, the number of cigarette cartridges that can be accommodated in one cigarette box 6 is set to an integer N, N = 50; setting a positioning code reader 5 to read the identification code of the 4 th entering cigarette box 6, namely a = 4; for convenience of explanation, the cigarette cartons are numbered 1, 2 and 3 … …, and the cigarette cartons enter a boxing machine in sequence; the cigarette carton real object is connected with the corresponding data of the cigarette carton in the carton identification code queue by a short line.
As shown in fig. 4, a cigarette pack (belonging to the 2 nd cigarette) with the serial number 52 is added after the pack reader 3 reading process and before the positioning reader 5 identifying process. According to the association method, when the 1 st cigarette is associated, the positioning identification code D (1) corresponds to T (4) in the code data queue of the cigarette box identification code, namely k1=4, and similarly k2= 53; the data corresponding to T (1) -T (4) is firstly dequeued, and since (k 2-k 1-a) =45, the 45 data of T (5) -T (49) are subsequently dequeued, so that the first cigarette case is associated with the carton identification code data of the 49 cigarettes of T (1) -T (49), and lacks the data of the cigarette carton with the serial number of 50. Then T (50) becomes the first element T (1) of the barcode data queue, and when the 2 nd cigarette is associated, it can be known in the same manner that k1=4 and k2=54, the data corresponding to T (1) -T (4) is first dequeued, and since (k 2-k 1-a) =46, the 46 data of T (5) -T (50) are subsequently dequeued, so that the 2 nd cigarette is associated with the barcode data of 50 cigarettes of T (1) -T (50), the corresponding barcode data has a serial number of 50-100, a cigarette carton with a serial number of 50 belonging to the 1 st cigarette is added, and the cigarette carton with a serial number of 52 is lacking. And then T (51) becomes a first element T (1) of the code data queue of the carton identification code, when the 3 rd cigarette is associated, the carton identification code completely corresponds to the carton real object, and errors cannot occur in subsequent association. The number of association errors in this case is 2.
As shown in fig. 5, the cigarette carton (belonging to the 2 nd cigarette carton) with the sequence number 52 is removed after the reading process of the carton code reader 3 and before the reading process of the positioning code reader 5. According to the association method, when the 1 st cigarette is associated, the positioning identification code D (1) corresponds to T (4) in the code data queue of the strip box identification code, namely k1=4, and similarly k2= 55; the first to be dequeued T (1) -T (4), and since (k 2-k 1-a) =47, the 47 data T (5) -T (51) are subsequently dequeued, so that the first cigarette pack is associated with the cartridge identification code data of the 51 cigarettes T (1) -T (51), and the data belonging to the 2 nd cigarette cartridge with the serial number 51 are added. Then T (52) becomes the first element T (1) of the barcode data queue, and when the 2 nd cigarette is associated, it is known in the same way that k1=4 and k2=54, the first cigarette is listed from T (1) to T (4), and since (k 2-k 1-a) =46, the 46 data of T (5) to T (50) are listed later, and therefore the 2 nd cigarette is associated with the barcode data of the 50 cigarettes of T (1) to T (50), corresponding to the barcode data of the cigarette carton with the serial number of 52 x-101 which is removed, and the cigarette carton with the serial number of 52 x which is missing. And then T (51) becomes a first element T (1) of the code data queue of the carton identification code, when the 3 rd cigarette is associated, the carton identification code completely corresponds to the carton real object, and errors cannot occur in subsequent association. The number of association errors in this case is 2.
As shown in fig. 6, after the reading process of the positioning code reader 5 is completed, a cigarette carton with the serial number 6 (belonging to the 1 st cigarette) is added. According to the association method, when the 1 st cigarette is associated, the positioning identification code D (1) corresponds to T (4) in the code data queue of the cigarette box identification code, namely k1=4, and similarly k2= 53; t (1) -T (4) are first dequeued, and since (k 2-k 1-a) =45, the 45 data T (5) -T (49) are subsequently dequeued, so that the first cigarette pack is associated with the cartridge identification code data for the 49 cigarettes T (1) -T (49), lacking the data for the added cigarette cartridge numbered 6. Then T (50) becomes a first element T (1) of the strip box identification code data queue, the strip box identification code completely corresponds to a strip box real object, and no error occurs in association of a subsequent cigarette box 6 such as a 2 nd box, a 3 rd box and the like and the strip box. The number of association errors in this case is 1.
As shown in fig. 7, after the reading process of the positioning code reader 5 is completed, the cigarette carton with the serial number 6 (belonging to the 1 st cigarette) is taken out. According to the association method, when the 1 st cigarette is associated, the positioning identification code D (1) corresponds to T (4) in the code data queue of the strip box identification code, namely k1=4, and similarly k2= 55; the data of 47 data of T (5) -T (51) are then listed since (k 2-k 1-a) =47 since T (1) -T (4) are listed first, so that the first cigarette pack is associated with the data of the carton identification code of 51 cigarettes of T (1) -T (51), and the data of the cigarette carton with the serial number of 6 taken out is added. And then T (52) is the first element T (1) of the strip box identification code data queue, the strip box identification code completely corresponds to the strip box real object, and no error occurs in association of the subsequent cigarette boxes 6 such as the 2 nd box, the 3 rd box and the like with the strip box. The number of association errors in this case is 1.
For the reasons of the equipment, the reasons for the failure of identification code identification are mainly: 1. the identification code cannot be analyzed due to unclear printing, fouling and the like; 2. it can be known from the correlation method that, in order to ensure the continuity of the queue data, the code reader needs to complete the resolution and enqueue of an identification code between two adjacent trigger signals, and needs to set a resolution time limit according to the actual equipment, and if the code reader does not resolve a result within the time limit due to some reason (such as inaccurate focusing), the identification is also considered as failed.
Among the 1 st causes of identification code identification failure, identification failure may generate false alarm data.
When the code scanning and reading of the bar box code reader 3 fails, replacing the two-dimensional code data which is correspondingly analyzed in the S1 with null data according to the error prompt data, and writing the null data into the corresponding position of the bar box identification code queue at the moment;
when the code scanning and reading of the positioning code reader 5 fails, replacing the two-dimensional code data which is correspondingly analyzed in the S2 with null data according to the error prompt data, and writing the null data into the corresponding position of the positioning identification code queue at the moment;
and (3) the cigarette box code reader 9 fails to scan and read codes, the bar code data which is correspondingly analyzed in the S3 is replaced by null data according to the error prompt data, and a null data is written in the corresponding position of the cigarette box bar code queue at the moment.
According to the abnormal condition, after the associated data of the first box is entered into the associated data queue (after S44), the associated data of the first box is analyzed, and if there is empty data or the number of the carton identification codes is not equal to the number of cigarette cartons in the boxing condition (for example, one carton of cigarettes has 50 cigarettes, that is, the number of the carton identification codes in the associated data is not equal to 50), the abnormality is judged, and the first box is prompted to read the error and marked.
Or before the strip box identification code data is associated with the first cigarette box identification code data of the cigarette box identification code data queue (before S44), if the positioning identification code data is empty data or the corresponding positioning identification code D (1) or D (2) data cannot be found in the strip box identification code data queue (namely K1=0 or K2= 0), judging that an abnormality occurs and prompting; then, S43 is corrected to: if K1=0 and K2 ≠ 0, the first (K2-a) data of the barcode data queue is dequeued by the bar box identification code; if K2=0 and K1 ≠ 0, the first (N + K1-a) data of the bar code data queue is dequeued, and if K1 and K2 are both 0, the first N data T (1) -T (N) of the bar code data queue are dequeued.
In the abnormal condition, if only the reading fails, the barrel identification code or the cigarette box identification code is replaced by the empty data, and only the error of the correlation result of the cigarette box in which the empty data is located is caused; if the positioning tag has empty data or the number of the carton identification codes is not equal to the number of the cigarette cartons in the boxing condition, the data dequeuing method can know that in addition to affecting the correlation correctness of the current cigarette carton, the actual number of cigarette cartons of the next cigarette carton and the number of the dequeuing tags may be equal or different, and the unequal situation is equivalent to one of the abnormal situations shown in fig. 4-7, so that the next cigarette carton may have correlation errors, and the total number of the correlation errors is between one carton and two cartons.
In summary, the cigarette carton and cigarette case code scanning correlation method for eliminating accumulated errors can judge whether correlation errors occur or not through correlation data of cigarette case identification codes and carton identification codes of the cigarette cases, remind is conducted, the number of the cigarette cases related to the errors is controlled within one case to two cases, influences on the correlation relation between the subsequent cigarette cases and the carton are reduced through eliminating the errors, and therefore correlation accuracy and algorithm stability are improved.
The above disclosure is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of changes or modifications within the technical scope of the present invention, and shall be covered by the scope of the present invention.
