Description

Technical Field

[0001] This application relates to the field of commercial tobacco logistics technology, and in particular to a device for collecting, associating, and correcting errors using QR codes on cigarette packs and cartons in a packaging machine. Background Technology

[0002] According to relevant regulations, each carton of cigarettes produced in various regions must have a QR code containing its relevant information printed on one side of each carton. Each carton's QR code is unique. In the tobacco industry, "carton-to-retailer" usually refers to a system that uses information technology such as QR codes to closely link the cigarette carton with the retailer, achieving full traceability from production and logistics to sales. According to relevant documents, the carton-to-retailer system must operate stably, and the sorting line efficiency must not be significantly lower than before, achieving 100% counting accuracy and 100% carton-to-retailer accuracy.

[0003] Currently, the pack-to-pack packaging machines and cigarette pack QR code collection and error correction devices installed on commercial tobacco logistics sorting lines can cause problems for orders with large total cigarette pack counts. When a retailer's order is sorted and a shortage alarm is triggered, some cigarette packs have already flowed into the back-end packaging machine. It is difficult for manual labor to find the unread cigarette packs, but the pack-to-pack correlation accuracy must reach 100%. Rescanning cigarette packs and handling problems will consume a lot of manpower. Utility Model Content

[0033] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0038] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0039] See appendix Figure 1 -Appendix Figure 6 , Figure 1 This illustration shows an overall structural diagram of a packaging machine cigarette pack QR code acquisition, association, and error correction device according to an embodiment of this application. The device is used for cigarette packs, each with a QR code. It includes a main body 1, with the packaging machine cigarette pack QR code acquisition, association, and error correction device located within the main body 1; a conveying mechanism 2, located inside the main body 1, used for conveying the cigarette packs; and multiple first barcode readers 6 and multiple second barcode readers 7. The first barcode readers 6 are located on one side of the conveying mechanism 2, and the multiple second barcode readers 7 are located on the other side of the conveying mechanism 2, all used for acquiring information from the QR code.

[0040] The conveying mechanism 2 is provided with multiple partitions 3 spaced apart along the conveying direction, and the workpiece to be tested is located between two adjacent partitions 3. The conveying mechanism 2 includes a frame 4, on which multiple first adjustment mechanisms 11 are installed. Any two of the first barcode reader 6, the second barcode reader 7 and the first adjustment mechanism 11 are provided accordingly. The first adjustment mechanism 11 is used to adjust the position and height of the corresponding first barcode reader 6 and the corresponding second barcode reader 7.

[0041] During operation, the conveyor mechanism 2 transports the cigarette packs between the partitions 3 sequentially to the wrapping machine 16 inside the main body 1. As the cigarette packs pass the first guard plate 8 and the second guard plate 9, the vision device 12 senses that the partition 3 has entered the barcode reader's reading range. At this time, multiple first barcode readers 6 and second barcode readers 7 on both sides are triggered to simultaneously capture and photograph the QR code. The collected QR code information of the cigarette packs is verified and associated with the order information of the cigarette packs through the associated software. Subsequently, the cigarette packs inside the partitions 3 are transported normally to the wrapping machine 16, where they are handled by the second cylinder 15 and then wrapped and packaged by the wrapping machine 16.

[0042] See appendix Figure 2 and attached Figure 6 The conveying mechanism 2 includes a first conveyor belt 201, and two second conveyor belts 202 are arranged on both sides of the first conveyor belt 201. A gap 203 is provided between each of the two second conveyor belts 202 and the first conveyor belt 201. Two positioning claws 301 are provided on the side wall of the partition plate 3, which is perpendicular to the conveying direction of the conveying mechanism 2 and faces the conveying mechanism 2. The two positioning claws 301 are correspondingly arranged with the two second conveyor belts 202. The positioning claws 301 are located in the gap 203 between the corresponding second conveyor belt 202 and the first conveyor belt 201, and are installed on the side of the corresponding second conveyor belt 202.

[0043] In some embodiments, in this application, the second conveyor belt 202 and the first conveyor belt 201 rotate synchronously, wherein the partition 3 is fixed to the side of the second conveyor belt 202 facing the first conveyor belt 201 by positioning claws 301. When the second conveyor belt 202 drives the partition 3 to rotate, the partition 3 remains stationary relative to the first conveyor belt 201 and isolates the cigarette packs.

[0044] In some embodiments, a fixing member is provided on the positioning claw 301, and the partition 3 is detachably installed on the second conveyor belt 202 through the fixing member. The specific type and structure of the fixing member are not limited here.

[0045] See appendix Figure 1 and attached Figure 4 The frame 4 is provided with two mounting plates 5 located on both sides of the conveying mechanism 2. Multiple first barcode readers 6 are mounted on one of the mounting plates 5, and multiple second barcode readers 7 are mounted on the other mounting plate 5. A first guard plate 8 is also provided between the multiple first barcode readers 6 and the conveying mechanism 2, and a second guard plate 9 is also provided between the multiple second barcode readers 7 and the conveying mechanism 2.

[0046] In some embodiments, a protective plate structure is designed to prevent the cigarette pack from colliding with the first barcode reader 6 and the second barcode reader 7 on both sides during the cigarette pack transportation process.

[0047] In some embodiments, the first guard plate 8 and the second guard plate 9 may be made of smooth and transparent materials such as transparent tempered glass or transparent acrylic to ensure good light transmission and to ensure that the QR code of the cigarette pack is exposed and conveyed forward along the edges of the first guard plate 8 and the second guard plate 9.

[0048] See appendix Figure 1 and attached Figure 3 The first adjustment mechanism 11 includes a fixed base 1101, which is mounted on the mounting plate 5. A first adjustment rod 1103 is detachably mounted on the fixed base 1101, and a first adjustment seat 1104 is slidably mounted on the first adjustment rod 1103. The first adjustment seat 1104 is used to adjust the vertical height of the first barcode reader 6 or the second barcode reader 7. A second adjustment seat 1108 is also slidably mounted on the first adjustment seat 1104, which is used to adjust the distance between the first barcode reader 6 or the second barcode reader 7 and the cigarette pack.

[0049] In some embodiments, to facilitate assembly and component replacement, thereby reducing usage and maintenance costs, the first adjusting rod 1103 is detachably mounted on the fixed base 1101. In actual use, the operator can adaptively adjust the distance between the partitions 3 according to actual needs, but it must be ensured that the partitions 3 are evenly distributed.

[0050] In some embodiments, when the vision device 12 senses that the partition 3 has entered the reading range of the first barcode reader 6 or the second barcode reader 7, because the cigarette packs are facing different directions, there will be barcodes on both sides. Therefore, multiple barcode readers on both sides are triggered to take pictures at the same time, and the barcodes of all cigarette packs in the current cigarette pack are continuously collected during the transportation process.

[0051] See appendix Figure 1 and attached Figure 3 The fixed base 1101 has an installation cavity 1102, and the first adjusting rod 1103 is detachably installed on the fixed base 1101 through the installation cavity 1102. The first adjusting base 1104 has a first through cavity 1105 and a second through cavity 1106 that are perpendicular to each other. The first adjusting base 1104 is slidably mounted on the first adjusting rod 1103 through the first through cavity 1105. The second adjusting rod 1107 is movably installed in the second through cavity 1106. The second adjusting base 1108 has a third through cavity 1109 and a fourth through cavity 1110 that are perpendicular to each other. The second adjusting base 1108 is movably mounted on the second adjusting rod 1107 through the third through cavity 1109. The multiple first barcode readers 6 and the multiple second barcode readers 7 are each provided with a first insert rod 1111. The multiple first barcode readers 6 and the multiple second barcode readers 7 are detachably installed on the corresponding second adjusting base 1108 through the first insert rod 1111.

[0052] In some embodiments, when the first adjusting seat 1104 reciprocates up and down along the first adjusting rod 1103 through the first through cavity 1105, the vertical height of the first barcode reader 6 and the second barcode reader 7 can be adjusted. When the second adjusting seat 1108 reciprocates relative to the first adjusting seat 1104 via the second adjusting rod 1107, the horizontal distance between the first barcode reader 6, the second barcode reader 7, and the cigarette pack can be adjusted. To facilitate quick installation of the first barcode reader 6 and the second barcode reader 7, the first barcode reader 6 and the second barcode reader 7 are detachably mounted on the second adjusting seat 1108 via the first insert rod 1111, and their swing angle relative to the cigarette pack can also be adjusted by rotating the first barcode reader 6 and the second barcode reader 7.

[0053] In some embodiments, after the height, angle and position of the first barcode reader 6 and the second barcode reader 7 are adjusted, the first adjustment seat 1104 and the second adjustment seat 1108 are fixed by fasteners, including but not limited to bolts, screws and other structures.

[0054] In some embodiments, if the focal depth and field of view of the first barcode reader 6 and the second barcode reader 7 on both sides cannot cover all the cigarette packs within the partition 3, the corresponding number can be increased on both sides to achieve full coverage scanning of the QR codes on the cigarette packs.

[0055] See appendix Figure 4 -Appendix Figure 5 The packaging machine's cigarette pack QR code acquisition and error correction device also includes a vision device 12 and a second adjustment mechanism 13. The vision device 12 is detachably mounted on the second adjustment mechanism 13, and the vision device 12 is positioned on one side of the conveying mechanism 2 via the second adjustment mechanism 13. The second adjustment mechanism 13 is used to adjust the position and height of the vision device 12. The second adjustment mechanism 13 includes a mounting base 1301, on which a first positioning rod 1302 is detachably mounted. A first motion seat 1303 is slidably mounted on the first positioning rod 1302, and the first motion seat 1303 is used to adjust the vertical height of the vision device 12. A second motion seat 1307 is also slidably mounted on the first motion seat 1303, and the second motion seat 1307 is used to adjust the distance between the vision device 12 and the partition 3.

[0056] In some embodiments, to facilitate assembly and component replacement, thereby reducing maintenance costs, the first positioning rod 1302 is detachably mounted on the mounting base 1301. In some embodiments, since the partitions 3 are evenly spaced on the conveying mechanism 2, when the vision device 12 detects that a partition 3 has moved to a predetermined position via photoelectric sensing, two partitions 3 are positioned between the first barcode reader 6 and the second barcode reader 7. This sends an electrical signal to the control panel 17 and the main control cabinet 18, subsequently activating the first barcode reader 6 and the second barcode reader 7.

[0057] In some embodiments, since the partitions 3 are evenly distributed, the vision device 12 can be disposed either above or below the conveying mechanism 2, without limitation.

[0058] See appendix Figure 4 -Appendix Figure 5 The first motion seat 1303 has a first positioning cavity 1304 and a second positioning cavity 1305 that are perpendicular to each other. The first motion seat 1303 is slidably mounted on the first positioning rod 1302 through the first positioning cavity 1304. The second positioning rod 1306 is movably installed in the second positioning cavity 1305. The second motion seat 1307 has a third positioning cavity 1308 and a fourth positioning cavity 1309 that are perpendicular to each other. The second motion seat 1307 is movably mounted on the second positioning rod 1306 through the third positioning cavity 1308. The vision device 12 is provided with a second insertion rod 1310. The vision device 12 is detachably mounted on the second motion seat 1307 through the second insertion rod 1310.

[0059] In some embodiments, when the first motion seat 1303 reciprocates up and down along the first positioning rod 1302 via the first positioning cavity 1304, the vertical height of the vision device 12 can be adjusted. When the second motion seat 1307 reciprocates relative to the first motion seat 1303 via the second positioning rod 1306, the horizontal distance between the vision device 12 and the partition 3 and the conveying mechanism 2 can be adjusted. To facilitate quick installation of the vision device 12, the vision device 12 is detachably mounted on the second motion seat 1307 via the second insertion rod 1310, and the swing angle of the vision device 12 relative to the partition 3 can be adjusted by rotating the second insertion rod 1310 or the vision device 12.

[0060] In some embodiments, after the height, angle and position of the vision device 12 are adjusted, the first motion seat 1303 and the second motion seat 1307 are fixed by fasteners, including but not limited to bolts, screws and other structures.

[0061] See appendix Figure 1 and attached Figure 4 The main body 1 also includes a wrapping machine 16, which is located at the output end of the conveying mechanism 2; the main body 1 also includes a first cylinder 14 and a second cylinder 15, which are respectively located at the input end and the output end of the conveying mechanism 2.

[0062] In some embodiments, the input end of the conveying mechanism 2 is also provided with an input device. The cigarette pack to be tested is conveyed to the vicinity of the input end of the conveying mechanism 2 through the relevant input device. At this time, under the action of the first cylinder 14, the relevant clamping device located at the output end of the first cylinder 14 will move the cigarette pack to be tested from the input device to the conveying mechanism 2 and place it between adjacent partitions 3.

[0063] After the barcode detection is completed, the relevant clamping device located at the output end of the second cylinder 15 will move the detected cigarette pack from the conveying mechanism 2 to the wrapping machine 16, and then wrap the cigarette pack through the wrapping machine 16.

[0064] See appendix Figure 1 and attached Figure 4 It also includes a control panel 17 and a main control cabinet 18, with the main control cabinet 18 electrically connected to the control panel 17; the main body 1 is provided with multiple protective doors 19; both mounting plates 5 are equipped with protective covers 10, and multiple first barcode readers 6 and multiple second barcode readers 7 are all set in the corresponding protective covers 10.

[0065] In some embodiments, the control panel 17 is mounted on the outer shell of the main body 1. Operators can input commands and achieve human-computer interaction through the input panel on the control panel 17. The control panel 17 transmits scanning information, command information, etc. to the main control cabinet 18 in real time via electrical connection. The collected QR code information of the cigarette packs is verified and associated with the order information of the cigarette packs through the precision packaging association software inside the control panel 17 and the main control cabinet 18.

[0066] In some embodiments, multiple openable protective doors 19 are designed to facilitate observation of the internal workings of the main body 1. To prevent external environmental influences and interference with the scanning operations of the first barcode reader 6 and the second barcode reader 7, a protective cover 10 is designed. For ease of subsequent maintenance and disassembly, the protective cover 10 is detachably mounted on the corresponding mounting plate 5.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
