Description

Technical Field

[0001] The present invention relates to the field of cigarette industry, in particular to a cigarette carton two-dimensional code reading system in a packaging machine and its working method. Background Technique

[0002] The statements in this part only provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] Building a traceability system covering all links such as industry, commerce, retail, and consumers in the whole product life cycle of cigarettes is an inherent need for the tobacco industry to improve the quality of cigarette products, enhance the level of market supervision, and gain insights into changes in consumption trends to achieve high-quality development, and is also an external requirement for implementing the World Health Organization Framework Convention on Tobacco Control.

[0004] In order to standardize the production and circulation management of cigarettes, it is required that cigarette industrial enterprises print two-dimensional codes on cigarette small boxes and cartons, and paste bar code labels on the case cigarettes produced to achieve the tracking and tracing of the whole product life cycle. When producing cigarettes, after the production of small boxes and cartons is completed, they will enter the packing and sealing machine for packaging. In the prior art, during the process of packing case cigarettes, the two-dimensional codes of case cigarettes are not accurately collected and read; the two-dimensional codes of cartons and case cigarettes are not associated, which results in the inability to unify the information of the box and the case cigarettes inside. Some manufacturers have carried out the association, but mainly through manual operation, without realizing automated operation. Manual association has problems such as high work labor intensity and waste of labor. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a cigarette carton two-dimensional code reading system in a packaging machine, which realizes the accurate association of the two-dimensional codes of case cigarettes and case packs, with relatively high association accuracy, and is beneficial to improving production efficiency.

[0006] In order to achieve the above purpose, the present invention is realized by the following technical solutions:

[0007] A cigarette carton two-dimensional code reading system in a packaging machine, comprising:

[0008] A first scanning component, which is arranged in the case cigarette conveying channel to obtain the two-dimensional code information of case cigarettes;

[0009] A second scanning component, which is arranged on the side of the case cigarette stacking part of the packaging machine to obtain the two-dimensional code information of multiple case cigarettes at a set layer in the case cigarette channel of the packaging machine. The second scanning component is provided with a plurality of second scanners, and each second scanner collects the two-dimensional code information of case cigarettes when multiple case cigarettes enter the case cigarette stacking part in sequence;

[0010] The controller is separately connected to the first barcode scanning component and the second barcode scanning component individually. When the scanning of some of the cigarette cartons on the current layer fails by some of the second barcode scanners, the controller completes the missing information based on the QR code information scanned by the second barcode scanners adjacent to the failing second barcode scanner. When the scanning of all the cigarette cartons on the current layer fails by multiple second barcode scanners in the second barcode scanning component, the controller marks all the cigarette cartons on the current layer as "NG".

[0011] In the cigarette carton QR code reading system of a cartoning machine as described above, the controller establishes the stacked cigarette carton queue information based on the sequence of QR codes of the cigarette cartons sent by the first barcode scanning component at the cigarette carton conveying channel. When the scanning of some or all of the cigarette cartons on the current layer fails by the second barcode scanners, the controller can also complete the QR codes on the current layer based on the established stacked cigarette carton queue information.

[0012] The cigarette carton QR code reading system of a cartoning machine as described above further includes a third barcode scanning component. The third barcode scanning component is installed behind the cigarette carton labeling mechanism of the cartoning machine. The third barcode scanning component obtains the QR code information of the cigarette cartons, and the third barcode scanning component is connected to the controller so that the controller associates the QR code information of the cigarette cartons with the QR code information of the cigarette cartons inside the cigarette cartons.

[0013] In the cigarette carton QR code reading system of a cartoning machine as described above, when the acquisition of the QR code information of the cigarette cartons fails by the third barcode scanning component, the operator manually associates the QR codes of the cigarette cartons through a barcode scanner gun.

[0014] When the acquisition of the QR code information of the cigarette cartons is successful by the third barcode scanning component, the controller checks whether there is an "NG" situation before. If so, the controller controls the cigarette carton conveying mechanism of the cartoning machine to stop, and the operator manually scans and completes the QR codes of the cigarette cartons through a barcode scanner gun.

[0015] The cigarette carton QR code reading system of a cartoning machine as described above further includes a first trigger sensor. The first trigger sensor is installed at the first bracket behind the cigarette carton labeling mechanism of the cartoning machine. The third barcode scanning component is also installed at the first bracket. The first trigger sensor is connected to the controller. Both the first trigger sensor and the third barcode scanning component are aligned with the cigarette carton conveying mechanism of the cartoning machine.

[0016] In the cigarette carton QR code reading system of a cartoning machine as described above, the first barcode scanning component is installed on one side of the cigarette carton conveying channel. A second trigger sensor is provided on the other side of the cigarette carton conveying channel from the first barcode scanning component. The second trigger sensor is connected to the controller.

[0017] A differential mechanism is provided in front of the appearance inspection mechanism of the cigarette carton conveying channel to create a spacing between adjacent cigarette cartons. The differential mechanism is set at an interval distance from the inlet end of the cigarette carton conveying channel.

[0018] There are six cigarette strip conveying channels, and a first code scanning component is arranged at each cigarette strip conveying channel. The above-mentioned cigarette strip channel of the packaging machine is arranged on the forward side of each cigarette strip conveying channel, and the second code scanning component is arranged at each cigarette strip channel of the packaging machine.

[0019] In a cigarette strip two-dimensional code reading and decoding system in a packaging machine as described above, a rejection mechanism is arranged at the cigarette strip conveying channel. The rejection mechanism is located on the forward side of the first code scanning component. The rejection mechanism is a linear drive mechanism and is connected to the controller. When the first code scanning component fails to collect the two-dimensional code information of the cigarette strip, the controller controls the rejection mechanism to reject the corresponding cigarette strip;

[0020] A material box is arranged on the opposite side of the cigarette strip conveying channel to the rejection mechanism;

[0021] In a cigarette strip two-dimensional code reading and decoding system in a packaging machine as described above, the second code scanning component is used to obtain the two-dimensional code information of multiple cigarette strips in the second layer at the stacked position of the cigarette strips of the packaging machine.

[0022] In a cigarette strip two-dimensional code reading and decoding system in a packaging machine as described above, the second code scanning component includes three second code scanners. The three second code scanners are at the same height, and the distance between adjacent two second code scanners is set. The multiple second code scanners are installed through a second bracket, and the second bracket is fixed on the side of the packaging machine.

[0023] In a cigarette strip two-dimensional code reading and decoding system in a packaging machine as described above, a distance is set between the second bracket and the outer push bar and insert plate of the packaging machine, and an opening for aligning with the cigarette strip two-dimensional code is opened on the outer push bar and insert plate.

[0024] Second, the present invention also provides a working method for a cigarette strip two-dimensional code reading and decoding system in a packaging machine, including the following content:

[0025] Obtain the two-dimensional code information of the cigarette strips at the cigarette strip conveying channel through the first code scanning component;

[0026] Obtain the two-dimensional code information of multiple cigarette strips at the set layer at the stacked position of the cigarette strips of the packaging machine through the second code scanning component;

[0027] When the code scanning of some cigarette strips in the current layer fails by some second code scanners, the controller completes the code according to the two-dimensional code information scanned by the second code scanner adjacent to the second code scanner;

[0028] When the code scanning of multiple cigarette strips in the current layer fails completely by multiple second code scanners in the second code scanning component, the controller marks all the multiple cigarette strips in the current layer as "NG".

[0029] The beneficial effects of the present invention are as follows:

[0030] 1) In the present invention, a first scanning component is provided at the cigarette strip conveying channel, that is, at the cigarette strip inspection station, and a second scanning component is provided at the cigarette strip two-dimensional code reading station. The scanning components are all connected to the controller. In this way, during the stacking process of cigarette strips, the two-dimensional codes of the stacked cigarette strips are collected, which is beneficial to the subsequent association of the two-dimensional code information of the same-piece cigarettes. Moreover, the second scanning component is provided with multiple second scanners. When the scanning of some of the current-layer cigarette strips by some of the second scanners fails, the controller completes the missing information according to the two-dimensional code information scanned by the second scanners adjacent to the failed second scanner, which is beneficial to improving the accuracy of precise association.

[0031] 2) In the present invention, the controller can establish the stacked cigarette strip queue information according to the two-dimensional code information of the cigarette strips collected by the first scanning component to assist the work of the second scanner. In this way, when the second scanning component fails to read the two-dimensional code information of the cigarette strips, the controller can complete the two-dimensional code of the current layer according to the stacked cigarette strip queue information.

[0032] 3) In the present invention, a third scanning component is provided. The third scanning component obtains the two-dimensional code information of the piece of cigarettes. In this way, the association between the two-dimensional code at the piece-of-cigarettes position and the two-dimensional codes of all the cigarette strips inside can be realized. The first trigger sensor feeds back information to the controller, and the controller controls the third scanning component to perform scanning, realizing the automation of the entire process of association, which is greatly beneficial to improving work efficiency.

[0033] 4) The overall reading code system of the present invention can realize the association operation by operating in parallel with the packaging machine, without adding upstream and downstream processes, with little modification to the packaging machine, without increasing the workload of on-site personnel, and can ensure the accuracy of association, having practical feasibility.

[0034] 5) In the present invention, in the case of all failures in the collection by the second scanning component, after the third scanning component scans successfully, the machine stops, and manual scanning is performed for manual association. In this way, the complete association between the piece of cigarettes and the cigarette strips inside is ensured, and manual work assists mechanical operation to ensure the accuracy of association.

[0035] 6) In the present invention, for multiple cigarette strip conveying channels, a first scanning component is provided at each one. Overall, the association between the cigarette strips in multiple cigarette strip conveying channels and the two-dimensional codes of the piece of cigarettes can be realized. A differential mechanism is provided at the cigarette strip conveying channel. The setting of the differential mechanism can create a spacing between adjacent two cigarette strips entering the cigarette strip conveying channel to ensure accurate scanning by the first scanning component.

Specific embodiments

[0043] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0044] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the present invention otherwise clearly indicates, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof;

[0045] As introduced in the background technology, there is a problem that the two-dimensional code of cigarette cartons is not accurately collected and read during the process of packing cigarette cartons in the prior art. To solve the above technical problems, the present invention proposes a cigarette carton two-dimensional code reading system in a packaging machine.

[0046] Embodiment 1

[0047] In a typical embodiment of the present invention, a cigarette case two-dimensional code reading system in a packaging machine includes:

[0048] A first code scanning component 6 is arranged at the cigarette case conveying channel 11 to obtain the two-dimensional code information of the cigarette case;

[0049] A second code scanning component 2 is arranged at the side of the cigarette case stacking position of the packaging machine to obtain the two-dimensional code information of multiple cigarette cases at a set layer at the cigarette case channel of the packaging machine. The second code scanning component is provided with a plurality of second code scanners, and each second code scanner collects the two-dimensional code information of the cigarette case when multiple cigarette cases enter the cigarette case stacking position in sequence;

[0050] A controller, the first code scanning component 6 and the second code scanning component 2 are respectively and independently connected to the controller. When the code scanning of some cigarette cases in the current layer by some second code scanners fails, the controller completes the code according to the two-dimensional code information scanned by the second code scanner adjacent to the second code scanner. When the code scanning of multiple cigarette cases in the current layer by multiple second code scanners in the second code scanning component all fails, the controller marks all the multiple cigarette cases in the current layer as "NG (meaning not passing)".

[0051] In addition, the controller establishes a stacked cigarette case queue information according to the two-dimensional code sequence of the cigarette cases sent by the first code scanning component at the cigarette case conveying channel. When the code scanning of some cigarette cases in the current layer by some or all second code scanners fails, the controller can also complete the two-dimensional code of the current layer according to the established stacked cigarette case queue information, so that there is no need for subsequent manual code scanning, improving work efficiency.

[0052] Specifically, the controller is a PLC controller, an industrial control computer or other types of controllers. The controller can be installed on the frame of the packaging machine. The controller can be independent of the control center of the packaging machine, or the controller can directly adopt the control center of the packaging machine.

[0053] The above-mentioned code reading system further includes a third code scanning component 9. The third code scanning component 9 is specifically an existing two-dimensional code scanner. The third code scanning component 9 is installed behind the cigarette labeling mechanism of the packaging machine part. The third code scanning component 9 obtains the two-dimensional code information of the cigarette. The third code scanning component is connected to the controller so that the controller associates the two-dimensional code information of the cigarette with the two-dimensional code information of the cigarette cases inside the cigarette.

[0054] It is easy to understand that when the third code scanning component fails to collect the two-dimensional code information of the cigarette, the artificial association of the two-dimensional code of the cigarette is carried out by a manual code scanner;

[0055] In some cases, when the third code scanning component 9 successfully collects the cigarette carton QR code information, the controller checks whether there is an "NG" before the cigarette carton. If there is still an "NG", the controller controls the cigarette carton conveying mechanism of the packaging machine to stop, and the operator manually scans the QR code of the cigarette carton with a code scanning gun to complete the manual code scanning, assisting the mechanical operation manually to ensure the accuracy of the association of the cigarette pack QR code information.

[0056] In addition, the code reading system further includes a first trigger sensor. When one side of the cigarette carton passes the first trigger sensor, the first trigger sensor sends a signal to the controller, and the controller controls the third code scanning component 9 to turn on. The first trigger sensor is installed at the first bracket 8 behind the cigarette carton labeling mechanism of the packaging machine. Refer to Figure 3 As shown, the third code scanning component 9 is installed at the first bracket 8. The first trigger sensor is connected to the controller. Both the first trigger sensor and the third code scanning component are aligned with the cigarette carton conveying mechanism of the packaging machine.

[0057] Specifically, the first bracket 8 is a portal bracket. The first bracket spans across the cigarette carton conveying mechanism 10 of the packaging machine. The first trigger sensor is arranged above the cigarette carton conveying mechanism 10 of the packaging machine. The first trigger sensor selects an existing photoelectric switch.

[0058] Regarding the first code scanning component, refer to Figure 4 As shown, the first code scanning component 6 is specifically a first code scanner. The first code scanner is installed on one side of the cigarette pack conveying channel 11. A second trigger sensor is arranged on the other side of the cigarette pack conveying channel 11 relative to the first code scanning component. The second trigger sensor is connected to the controller. After the second trigger sensor detects a cigarette pack, it sends a signal to the controller, and the controller controls the first code scanning component 6 to open;

[0059] It should be noted that for the solution of six cigarette pack conveying channels, the six cigarette pack conveying channels are divided into two groups. Refer to Figure 4 As shown, each group is provided with three cigarette pack conveying channels. These three cigarette pack conveying channels are arranged vertically. A first code scanning component is arranged at each cigarette pack conveying channel. A packaging machine cigarette pack channel is arranged on the forward side of each cigarette pack conveying channel. A second code scanning component is arranged on the side of the cigarette pack stacking part at each packaging machine cigarette pack channel. There is one third code scanning component arranged according to the original structure of the packaging machine. In this way, the association between the cigarette cartons corresponding to the six packaging machine cigarette pack channels and their respective cigarette carton corresponding QR codes is realized.

[0060] Specifically, the controller makes the packaging machine cigarette pack channels correspond to the second code scanning components one by one. In this way, the scanning information obtained by the controller from the second code scanning components corresponds to the corresponding packaging machine cigarette pack channels, and the arrival of the packaging machine cigarette pack channels at the third code scanning component is also controlled in sequence. In this way, the association between the cigarette packs and the cigarette carton QR codes can be realized.

[0061] It is easily understood that a differential mechanism 12 is provided on the front side of the cigarette carton conveying channel 11 by the appearance inspection mechanism 13 to create a spacing between adjacent cigarette cartons. The differential mechanism 12 is set at an interval distance from the inlet end of the cigarette carton conveying channel 1. The differential mechanism 12 is an existing cigarette carton differential mechanism. Specifically, the differential mechanism 12 includes a portal frame that straddles each conveying channel in the cigarette carton conveying channel. A rotatable friction block is provided on one side of the transverse section of the portal frame facing the conveying channel. The speed of the cigarette cartons is reduced by the friction block to control the distance between adjacent two cigarette cartons.

[0062] In this embodiment, a rejection mechanism 14 is provided on one side of the first code scanning assembly 6. The rejection mechanism 14 is a linear drive mechanism and is connected to the controller. When the first code scanning assembly 6 fails to collect the two-dimensional code information of the cigarette carton, the controller controls the rejection mechanism 14 to reject the corresponding cigarette carton. A material box 15 is provided on the other side of the cigarette carton conveying channel 1 by the rejection mechanism 14. In this way, after the rejection mechanism 14 rejects the cigarette carton, the cigarette carton can enter the material box 15.

[0063] The linear drive mechanism can specifically select a linear drive electric cylinder. The fixed end of the linear drive electric cylinder is fixed to the frame of the cigarette carton conveying channel 1, and the telescopic end of the linear drive electric cylinder is located above the conveying channel in the cigarette carton conveying channel.

[0064] It should be explained that the second code scanning assembly 2 is used to obtain the two-dimensional code information of multiple cigarette cartons in the second layer (i.e., the second lifting position after the cigarette cartons enter the stacking box) at the cigarette carton stacking position of the packaging machine; the third code scanning assembly is used to obtain the two-dimensional code information of multiple cigarette cartons in the second layer (i.e., the second lifting position after the cigarette cartons enter the stacking box) of the stacked cigarette cartons at the outer lane. Because the cigarette cartons at the cigarette carton stacking position of the packaging machine can be gradually lifted, the two-dimensional code information of all cigarette cartons at the cigarette carton stacking position of the packaging machine can be collected.

[0065] Reference Figure 1 As shown, the second code scanning assembly 2 includes multiple second code scanners. Specifically, three second code scanners can be set. The distance between adjacent two second code scanners is set at an interval. The multiple second code scanners are installed by a second bracket 3. The second bracket 3 straddles the conveying mechanism of the packaging machine. The second bracket can also be a portal type. The second code scanner is inclined downward relative to the conveying mechanism of the packaging machine. The scanning end of the second code scanner 2 is aligned with the second layer at the cigarette carton stacking position of the packaging machine to align with the C surface (end face) of five cigarette cartons in the second layer.

[0066] Among them, the code scanners are all existing two-dimensional code scanners.

[0067] In some examples, the second bracket can be an inclined bracket. The inclined bracket is provided at the frame of the conveyor mechanism of the packaging machine. The third bracket is located outside the outer pushing strip and inserting plate of the packaging machine. The outer pushing strip and inserting plate 5 (which is an existing structural part of the packaging machine at the outer side of the stacked cigarette bars of the packaging machine) is provided with an opening aligned with the cigarette bar two-dimensional code. By setting the opening at 5 as such, refer to Figure 2 As shown, the outer pushing strip and inserting plate 5 is a structural part of the existing packaging machine, which is used to limit the cigarette bars on the outer path.

[0068] In the code reading system provided in this embodiment, a first code scanning component 6 is provided at the cigarette bar conveying channel, that is, at the cigarette bar inspection station. A second code scanning component 2 is provided at the cigarette bar two-dimensional code reading station. The code scanning components are all connected to the controller. The two-dimensional code information of the cigarette bars collected by the first code scanning component 6 is used to establish the stacked cigarette bar queue information. In this way, the reading of the two-dimensional code during the cigarette bar stacking process can be realized. Moreover, if the reading fails, the two-dimensional code of the current layer can be complemented according to the stacked cigarette bar queue information. By the first code scanning component 6 assisting the work of the second code scanning component 2, it is beneficial to improve the accuracy of precise association; and through the setting of the third code scanning component 9, the association between the case of cigarettes and the two-dimensional code of the cigarette bars inside it can be realized, and the association of the whole process is basically automated, which greatly helps to improve work efficiency.

[0069] Embodiment Two

[0070] This embodiment provides a working method for a cigarette bar two-dimensional code reading system in a packaging machine, including the following contents:

[0072] Obtain the two-dimensional code information of multiple cigarette bars at the set layer at the cigarette bar channel of the packaging machine through the second code scanning component 2. The second code scanning component is provided with multiple second code scanners, and each second code scanner sequentially collects the two-dimensional code information of the cigarette bars when the multiple cigarette bars enter the cigarette bar stacking place in sequence;

[0073] When the code scanning of some of the cigarette bars on the current layer by some of the second code scanners fails, the controller complements according to the two-dimensional code information scanned by the second code scanners adjacent to the second code scanner;

[0074] When the code scanning of all the multiple cigarette bars on the current layer by all the second code scanners in the second code scanning component fails, the controller marks all the multiple cigarette bars on the current layer as "NG";

[0075] In some examples, the controller establishes the stacked cigarette bar queue information according to the sequence of the two-dimensional codes of the cigarette bars sent by the first code scanning component at the cigarette bar conveying channel. When the code scanning of some or all of the cigarette bars on the current layer by some of the second code scanners fails, the controller can also complement the two-dimensional code of the current layer according to the established stacked cigarette bar queue information;

[0076] Obtain the two-dimensional code information of the case of cigarettes through the third code scanning component and send it to the controller, and the controller associates the two-dimensional code information of the case of cigarettes with the two-dimensional code information of the inner cartons of cigarettes in the case of cigarettes;

[0077] When the third code scanning component fails to collect the two-dimensional code information of the case of cigarettes, manually associate the two-dimensional code of the case of cigarettes through a code scanning gun; when the third code scanning component successfully collects the two-dimensional code information of the case of cigarettes, the controller checks whether there is still "NG" for the case of cigarettes before. If so, the controller controls the case of cigarettes conveying mechanism of the packaging machine to stop. When the third code scanning component fails to collect the two-dimensional code information of the case of cigarettes, manually scan and complete the two-dimensional code of the case of cigarettes through a code scanning gun. When all the collections are successful, use the collected results as the final results for association;
