Technical Field

[0002] Currently, the tobacco industry uses QR code scanning on cigarette packs at the packaging machine's inlet and outlet to more accurately determine when and where the packs entered and completed production. However, cigarette packs pass through multiple packaging stations on the machine, and the equipment parameters for each pack at the same station are inconsistent, such as corresponding operating speeds and heating temperatures. Furthermore, since the same pack passes through multiple stations, it contains the equipment parameters and quality inspection information from each station. There is still no method to match the equipment status information and quality inspection information from each production station on the packaging machine to the specific cigarette pack, thus determining the equipment status and quality conditions at each station.

[0035] Beneficial effects:

[0036] The technical solution provided in this application reads the QR code information on the entire cigarette pack or its components passing through the packaging machine station using a QR code reader installed at the station, and records the reading time to form a QR code information sequence.

[0043] The following will refer to Figure 1 and Figure 2 A specific implementation method according to this application is described.

[0044] like Figure 1 As shown in the figure, this application provides a method for acquiring tobacco packaging production data, the method including:

[0045] S1. Obtain the first timing relationship. The first timing relationship is the timing relationship of the cigarette pack as a whole or its components completing specific packaging actions at various workstations of the packaging machine when the packaging machine completes the packaging of a cigarette pack.

[0046] In some embodiments, obtaining the first timing relationship includes: numbering each station of the packaging machine sequentially as 1, 2, 3... according to the timing sequence of a cigarette pack or its components completing specific packaging actions at each station of the packaging machine; and using the numbering information of each station of the packaging machine as the first timing relationship.

[0047] In some embodiments, the cigarette pack as a whole or its components complete specific packaging actions at various stations of the packaging machine, including:

[0048] The cigarette pack and frame paper are packaged at the frame paper packaging station of the packaging machine. The frame paper is folded and wrapped around the outside of the cigarette pack before the frame paper cigarette pack is output.

[0049] The packaging process of the cigarette pack and the film paper is completed at the film paper packaging station of the packaging machine. The film paper is folded and wrapped around the outside of the cigarette pack, and then the cigarette pack is output as a finished product.

[0050] The packaging process of the cigarette pack and the label paper is completed at the label paper packaging station of the packaging machine. After the label paper is folded and wrapped around the outside of the cigarette pack, the cigarette pack is output as a package.

[0051] S2. The QR code information on the whole cigarette pack or its components that have passed through the first station of the packaging machine is read by the QR code reader installed on the first station of the packaging machine, and the reading time is recorded to form a first sequence; the first station is the station on the packaging machine that is equipped with a QR code reader, and the first sequence includes multiple QR code information arranged according to the reading time.

[0052] In some embodiments, the first station of the packaging machine includes multiple stations on the packaging machine equipped with QR code readers;

[0053] The first sequence includes one or more data sequences; the QR code information read by the QR code reader installed at each workstation forms a separate data sequence according to the reading time.

[0054] In some embodiments, a QR code is printed on the label paper of the cigarette pack. The first station may include several stations such as the packaging machine inlet, key process points, and outlet through which the label paper passes. That is, QR code readers are installed at several points such as the packaging machine inlet, key process points, and outlet through which the label paper passes, and the QR code of each label paper passing through these points can be read to obtain several sets of cigarette pack QR code data sequences containing timestamp information.

[0055] S3. The production data of the cigarette packs or their components passing through the second station of the packaging machine are collected by the data acquisition device installed on the second station of the packaging machine, and the collection time is recorded to form a second sequence. The second sequence includes multiple production data arranged according to the collection time. The second station is the station on the packaging machine where the data acquisition device is installed.

[0056] In some embodiments, the first station of the packaging machine includes multiple stations on the packaging machine equipped with data acquisition devices;

[0057] The number of data acquisition devices is more than one;

[0058] The second sequence includes more than one data sequence; each workstation corresponds to a different type of production data, which is formed into a separate data sequence according to the collection time.

[0059] In some embodiments, a data acquisition device installed on the second station of the packaging machine collects production data of the entire cigarette pack or its components passing through the second station of the packaging machine, including: data acquisition device installed on the second station of the packaging machine collects processing time data, equipment status data and quality inspection data of the entire cigarette pack or its components passing through the second station of the packaging machine.

[0060] Based on unified time synchronization of equipment, by collecting equipment status data, various status data sequences of equipment containing timestamp information can be obtained, such as operating speed, air pressure, key process parameters, etc.; at the workstations of the packaging machine with sensors, by collecting quality inspection data, several sets of workstation quality inspection data sequences containing timestamp information can be obtained.

[0061] S4. For the first cigarette pack, the first data is obtained by searching in the first sequence based on the QR code information on the first cigarette pack; the first cigarette pack is the cigarette pack for which production data needs to be obtained; the first data is the QR code information corresponding to the first cigarette pack in the first sequence;

[0062] S5. Based on the position of the first data in the first sequence and the first temporal relationship, obtain the position of the second data of the first cigarette pack in the second sequence, and thus find the second data in the second sequence; the second data is the production data corresponding to the first cigarette pack as a whole or its components in the second sequence; the second data is the production data of the first cigarette pack.

[0063] In some embodiments, obtaining the position of the second data of the first cigarette pack in the second sequence based on the position of the first data in the first sequence and the first temporal relationship includes:

[0064] Let z be the index of the first data in the first sequence;

[0065] Based on the first time sequence relationship, determine the number i of the first workstation and the number j of the second workstation;

[0066] Calculate the interval y between the number i of the first workstation and the number j of the second workstation, i.e., y = ji;

[0067] Then the second data of the first cigarette pack has the sequence number z+y in the second sequence.

[0068] In station-based packaging equipment, the product undergoes specific packaging actions sequentially at multiple stations, with a fixed temporal relationship between each station. The embodiments described above, based on this temporal relationship between the packaging machine stations, obtain the correspondence between the QR code data of cigarette packs collected at each station and the cigarette pack production data. Utilizing the fixed temporal relationship between the packaging machine stations, by comparing the QR code data sequences containing timestamp information and the cigarette pack production data sequences according to their respective station number intervals, the production data corresponding to each cigarette pack at each station can be obtained.

[0069] For each of the first and second workstations, data is collected once after each cigarette pack or its components have passed through, generating a QR code or a piece of production data. For the same workstation, multiple QR code entries or production data entries collected sequentially form a data sequence in chronological order. It's important to note that the data collection times between workstations do not need to be synchronized. For example, if a packaging machine can produce 400 cigarette packs per minute, then the production cycle for each pack is 150ms. Therefore, each workstation only needs to complete one data collection within each 150ms cycle; the collection times between workstations do not need to be at the same time. For instance, the first workstation can start collecting data at the 5th second of each 150ms cycle, and the second workstation can start collecting data at the 50th second of each 150ms cycle, but the interval between their data collection cycles is always 150ms.

[0070] Based on the time sequence of the packaging machine workstations, the correspondence between the QR code sequences collected at each workstation and the production data sequences is obtained. For example, if the interval between the workstation number and the scanning workstation is y, then the production data sequences / QR code sequences collected by the data acquisition devices of these two workstations will be separated by y data points in the same cycle. Therefore, when matching the QR code sequence with the production data sequence, combined with the known workstation number interval, the production data of the cigarette pack at a certain workstation can be accurately matched. Figure 2 As shown, the interval between the x-th workstation after the trademark paper enters and the workstation number of the trademark paper entry workstation is x. The QR code sequence D2 collected by the x-th workstation after the trademark paper enters and the QR code sequence collected by the trademark paper entry workstation are separated by x data points in the same cycle. Similarly, the interval between the y-th workstation after the trademark paper enters and the workstation number of the trademark paper entry workstation is y. The production data sequence D3 collected by the y-th workstation after the trademark paper enters and the QR code sequence collected by the trademark paper entry workstation are separated by y data points at the same moment.

The execution order of the steps in this application is not limited by the order described above.
