Description

Technical Field

[0001] This utility model relates to the field of cigarette manufacturing, and in particular to a system for verifying and rejecting cigarette box-related information. Background Technology

[0002] The tobacco industry has begun to fully adopt "box-carton-package" linkage technology to enhance the tracking and verification capabilities of cigarettes. When consumers purchase cigarettes, scanning the QR codes on the box, carton, and package allows them to monitor the entire production process in real time, including raw material procurement, manufacturing, transportation, storage, and finally, the product reaching the consumer. This technology makes tracking quality issues more precise. Currently, "box-carton-package" linkage technology has become the primary means of verifying the authenticity and quality traceability of tobacco products. Therefore, the high accuracy and coverage of QR codes are particularly important.

[0003] Current cigarette box verification methods only perform verification at the verification point and do not have a rejection function. When a cigarette box with a verification error occurs, it will cause the sealing machine line to stop, affecting the operation of the entire production line.

[0004] To elaborate, current methods using barcode scanners to verify the "box-label-item" association information can accurately identify erroneous QR codes. However, when errors occur, the cigarette box needs to be manually located and removed; and if necessary, the production line needs to be stopped for investigation, impacting its operation. Therefore, the existing technical solution has at least the following shortcomings: it lacks the function of automatically removing erroneous cigarette boxes, requiring manual location and removal. Manual location and removal necessitates trained and experienced personnel, increases the workload of operators, and cannot eliminate missed or incorrect detections due to manual operation. Utility Model Content

[0005] In view of the above, the present invention aims to provide a cigarette box association information verification and rejection system that can remove erroneous QR codes on cigarette boxes without shutting down the system.

[0006] The technical solution adopted in this utility model is as follows:

[0007] This utility model provides a system for verifying and removing cigarette box-related information, including:

[0008] Industrial control computer, rejection device, first sensor, second sensor, rejection smoke box buffer area, sweeping dock, and two conveyor chains;

[0009] The rejection device is arranged between the two conveyor chains and below the conveyor chains, and the rejection cigarette box buffer area is arranged on one side of one of the conveyor chains and corresponds to the position of the rejection device.

[0010] The first sensor and the scanning dock are disposed on one side in front of the conveyor chain. The first sensor is used to detect the cigarette box and trigger the scanning dock to read the QR code.

[0011] The second sensor is configured on one side of the conveyor chain and corresponds to the position of the rejection device, and is used to detect abnormal cigarette boxes and trigger the rejection device to work;

[0012] The direction of the rejection belt on the rejection device is perpendicular to the direction of the transport chain. The rejection device, through lifting and lowering and the operation of the rejection belt, transports the abnormal cigarette box from the rejection port on one side of the transport chain, which is close to the rejection box buffer area, to the rejection box buffer area.

[0013] The rejection device, the first sensor, the second sensor, and the sweeping dock are respectively connected to the industrial control computer's electrical signals.

[0014] In at least one of the possible implementations, the rejection device includes: a PLC controller, a lifting cylinder, a lifting platform, a servo motor, a rotating roller, and a toothed belt;

[0015] The servo motor is deployed on the lifting platform, and the servo motor drives the rotating roller to rotate through the toothed belt, and the rejection belt is connected to the rotating roller;

[0016] The lifting cylinder is used to support and raise / lower the lifting platform, and the PLC controller is connected to the servo motor, the lifting cylinder, and the industrial control computer for electrical signals.

[0017] In at least one of the possible implementations, a third sensor connected to the industrial control computer is disposed on one side of the conveyor chain and in front of the rejection device. The third sensor cooperates with the second sensor to provide a signal indicating that the abnormal smoke box is in position, the signal indicating that the abnormal smoke box is facing the rejection port.

[0018] In at least one of the possible implementations, a fourth sensor connected to the industrial control electromechanical signal is disposed on one side of the conveyor chain and near the rejection port. The fourth sensor is used to provide a detachment signal of the abnormal smoke box, which indicates that the abnormal smoke box has detached from the conveyor chain and entered the rejection smoke box buffer area.

[0019] In at least one possible implementation, a plurality of rollers are arranged on the rejection smoke box buffer area, the rollers being used to assist in the transport of abnormal smoke boxes within the rejection smoke box buffer area.

[0020] In at least one possible implementation, the industrial computer includes an industrial touch screen configured on one side of the conveyor chain.

[0021] Compared with existing technologies, the main design concept of this utility model lies in adding an automatic QR code verification and rejection device to the cigarette box conveying production line. This device monitors the quality inspection data and anomalies of each cigarette box in real time, and verifies and rejects cigarette boxes with incorrect "box-condition-item" association information, achieving automatic rejection. Specifically, it includes an industrial control computer, a rejection device, a first sensor, a second sensor, a rejection cigarette box buffer area, a scanning dock, and two conveyor chains. The first sensor triggers the scanning dock to read the code, and after the industrial control computer verifies the anomaly, it activates the rejection device. When the second sensor detects an abnormal cigarette box, the rejection device lifts it and changes its conveying direction, sending the abnormal cigarette box into the buffer area. The rejection device then resets to await the next anomaly detection. This utility model can significantly reduce the workload of manual verification and rejection operations and reduce the number of downtimes on the conveying production line, thereby greatly improving equipment operating efficiency. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will be further described below with reference to the accompanying drawings, wherein:

[0023] Figure 1 A schematic diagram of the cigarette box association information verification and rejection system provided in this embodiment of the utility model;

[0024] Figure 2 An internal side view of the rejection device provided in an embodiment of this utility model. Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] This utility model proposes an embodiment of a cigarette box association information verification and rejection system, specifically, as follows: Figure 1 As shown, it includes: an industrial control computer 1, a rejection device 2, a first sensor 4, a second sensor 6, a rejection smoke box buffer area 8, a sweeping dock 10, and two conveyor chains 11.

[0027] The rejection device 2 is arranged between the two conveyor chains 11 and below the conveyor chains 11, and the rejection cigarette box buffer area 8 is arranged on one side of one of the conveyor chains 11 and corresponds to the position of the rejection device 2.

[0028] The first sensor 4 and the scanning dock 10 are arranged in front of one side of the conveyor chain 11 (relative to the running direction of the conveyor chain 11). The first sensor 4 is used to detect the cigarette box and trigger the scanning dock 10 to read the QR code.

[0029] The second sensor 6 is disposed on one side of the conveyor chain 11 and corresponds to the position of the rejection device 2, and is used to detect the detected abnormal cigarette boxes and trigger the rejection device 2 to work.

[0030] The rejection belt 3 on the rejection device 2 runs in a direction perpendicular to the running direction of the conveyor chain 11. The rejection device 2, through lifting and lowering and the running of the rejection belt 3, transports the detected abnormal cigarette boxes from the rejection port 12 to the rejection cigarette box buffer area 8. It should be added that by setting up a buffer area, multiple erroneous cigarette boxes can be buffered, reducing the urgency of handling erroneous cigarette boxes.

[0031] The rejection device 2, the first sensor 4, the second sensor 6, and the sweeping dock 10 are all electrically connected to the industrial control computer 1.

[0032] Combination Figure 2 In some preferred embodiments, the rejection device 2 may specifically include: a PLC controller 21, a lifting cylinder 22, a lifting platform 23, a servo motor 24, a rotating roller 25, and a toothed belt 26; the servo motor 24 is deployed on the lifting platform 23, and the servo motor 24 drives the rotating roller 25 to operate through the toothed belt 26, and the rejection belt 3 is connected to the rotating roller 25; the lifting cylinder 22 is used to support and lift the lifting platform 23; the PLC controller 21 is electrically connected to the servo motor 24, the lifting cylinder 22 (and its matching solenoid valve), and the industrial computer 1.

[0033] Based on this concept, when an abnormal cigarette box is detected by the industrial control computer 1 using mature scanning and comparison technology, the rejection device 2 is triggered to lift the abnormal cigarette box in a lifting manner and change the conveying direction, so as to transfer the cigarette box to the rejection cigarette box buffer area 8. After completing the task of transferring the abnormal cigarette box, the rejection device 2 needs to descend in time to ensure the normal conveying of other cigarette boxes on the conveying chain 11.

[0034] Therefore, in order to reliably achieve stable rejection of abnormal smoke boxes and reliable transport and resetting, the following two preferred solutions can also be configured in other embodiments of this utility model:

[0035] Firstly, a third sensor 5, electrically connected to the industrial control computer 1, is configured on one side of the conveyor chain 11 and in front of the rejection device 2 (relative to the running direction of the conveyor chain 11). The third sensor 5, in conjunction with the second sensor 6, is used to provide an abnormal cigarette box arrival signal. The arrival signal indicates that the abnormal cigarette box is facing the rejection port 12. In actual operation, specifically, the second sensor 6 may detect the abnormal cigarette box, and the third sensor 5 may report that the abnormal cigarette box has moved out of its detection range. Thus, the positions of the second and third sensors can be set according to the actual running speed, cigarette box specifications, rejection port size, etc.

[0036] Secondly, a fourth sensor 7, which is electrically connected to the industrial control computer 1, is disposed on one side of the conveying chain 11 and near the rejection port 12. The fourth sensor 7 is used to provide an abnormal smoke box detachment signal, which indicates that the abnormal smoke box detaches from the conveying chain 11 and enters the rejection smoke box buffer area 8.

[0037] Based on this concept, several rollers 9 are configured on the rejection smoke box buffer area 8 to assist in the transportation of abnormal smoke boxes within the rejection smoke box buffer area 8.

[0038] Finally, it can be added that the aforementioned industrial control computer 1 can preferably refer to an industrial touch screen configured on one side of the conveyor chain 11, and this utility model does not limit or elaborate on this.

[0039] Based on the above embodiments, the working mechanism of this utility model can be illustrated as follows: When the cigarette box moves along the conveyor chain to the first sensor, it triggers the scanning dock to scan the code. The industrial control computer receives the scanning signal and verifies the "box-condition-item" association information of the cigarette box. If the verification fails, the industrial control computer can send a rejection signal to the rejection device. At this time, it can be understood that the rejection device is in a standby state. When the abnormal cigarette box moves to the second sensor and simultaneously leaves the third sensor, it indicates that the abnormal cigarette box is in place. The PLC controller of the rejection device controls the lifting cylinder to lift up, driving the lifting platform to move upward and causing the rejection roller to rotate upward. The abnormal cigarette box is lifted and transported to the rejection buffer area by the rotation of the rejection belt.

[0040] When an abnormal cigarette box enters the rejection buffer area and, with the help of rollers, moves it out of the detection range of the fourth sensor at the rejection port, it indicates that the entire abnormal cigarette box has entered the buffer zone. At this point, the rejection device completes its task and is driven to descend by its PLC controller, while the rejection belt on it stops running. Through the above process, the automatic verification and automatic rejection of the cigarette box's "box-condition-item" association information is completed.

[0041] In summary, the main design concept of this utility model lies in adding an automatic QR code verification and rejection device to the cigarette box conveying production line. This device monitors the quality inspection data and anomalies of each cigarette box in real time, verifying and rejecting cigarette boxes with incorrect "box-condition-item" association information, thus achieving automatic rejection. Specifically, it includes an industrial control computer, a rejection device, a first sensor, a second sensor, a rejection cigarette box buffer area, a scanning dock, and two conveyor chains. The first sensor triggers the scanning dock to read the code, and after the industrial control computer verifies the anomaly, it activates the rejection device. When the second sensor detects an abnormal cigarette box, the rejection device lifts it and changes its conveying direction, sending the abnormal cigarette box into the buffer area. The rejection device then resets to await the next anomaly detection. This utility model can significantly reduce the workload of manual verification and rejection operations and reduce the number of downtimes on the conveying production line, thereby greatly improving equipment operating efficiency.

[0042] In this embodiment of the invention, any use of terms expressing location is based on a relative concept of the embodiment. Furthermore, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent the existence of A alone, A and B simultaneously, or B alone. A and B can be singular or plural.
