Description

Technical Field

[0001] The present invention relates to the technical field of finished cigarette production, and more specifically, to a QR code-associated error prevention method and system for finished cigarette products. Background Art

[0002] Based on the requirements of the industrial "box condition" association management system, the cigarette manufacturing process requires accurate association of QR codes between boxes, cartons, and individual cigarettes. Failure to do so will impact the normal shipment of individual cigarettes. Currently, incorrect associations often occur at the case sealing machine, causing incorrectly reported data anomalies in the association information. This can lead to the flow of abnormally associated individual cigarettes into the finished product warehouse, causing subsequent stockpiling and significant waste of manpower and resources, leading to increased production costs. Therefore, preventing incorrect associations in the sealing of finished cigarette cases and reducing this waste of manpower and resources is of vital importance. Summary of the Invention

[0003] The present invention provides a QR code association error prevention method and system for finished cigarette products, which solves the problem that the existing cigarette finished product packaging often causes associated information errors due to blockage, and requires a large amount of manpower and material resources to correct the errors. It can prevent the associated information errors of finished cigarette products, improve the production management level, and reduce production costs.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] On both sides of the belt conveyor after the second push of the carton sealer, a three-push photoelectric device is installed to detect smoke on the conveyor belt between the carton sealer and the coding machine;

[0007] When the three-push photoelectric device detects a cigarette carton, the cigarette carton sequence value corresponding to the cigarette carton in the second-push variable signal is transferred to the third-push variable, so that the second-push variable signal is no longer associated with the cigarette carton code of the coding machine;

[0008] A four-push photoelectric device is set in front of the coding machine's coding position to detect smoke at the coding machine's coding position;

[0009] When the four-push photoelectric device detects a cigarette carton, the cigarette carton sequence value in the three-push variable signal is transferred to the four-push variable, and the four-push variable is associated with the cigarette carton code printed by the coding machine.

[0010] Preferably, it also includes:

[0011] Carton sealing machine outlet is checked for blockage. If there is blockage, the secondary variable signal and the corresponding cigarette are re-confirmed for the cigarette sequence.

[0012] Preferably, it also includes:

[0013] A push photoelectric device is set up to detect whether the cigarettes are pushed into the carton from the conveyor belt and have been arranged neatly.

[0014] Preferably, it also includes:

[0015] A two-push photoelectric device is set at the folding station to detect whether the carton is pushed to the folding station. If so, the carton is sealed and the sealing tape is applied, and the serial value of the cigarette carton is confirmed.

[0016] Preferably, the one-push photoelectric device, the two-push photoelectric device, the three-push photoelectric device and the four-push photoelectric device all use photoelectric sensors.

[0017] The present invention also provides a QR code-associated error prevention system for finished cigarette products, comprising: a controller, a three-push photoelectric device, and a four-push photoelectric device;

[0018] The controller is respectively connected to the carton sealing machine, the coding machine, the three-push photoelectric device and the four-push photoelectric device by signal;

[0019] The three-push photoelectric device is arranged on both sides of the belt conveyor after the second push of the carton sealing machine to detect smoke on the conveyor belt between the carton sealing machine and the coding machine;

[0020] When the three-push photoelectric device detects a cigarette case, the controller transfers the cigarette carton sequence value corresponding to the cigarette case in the second-push variable signal to the third-push variable, so that the second-push variable signal is no longer associated with the cigarette case code of the coding machine;

[0021] The four-push photoelectric device is arranged before the coding position of the coding machine to detect smoke at the coding position of the coding machine;

[0022] When the four-push photoelectric device detects a cigarette carton, the controller transfers the cigarette carton sequence value in the three-push variable signal to the four-push variable, and associates the four-push variable with the cigarette carton code printed by the coding machine.

[0031] In order to more clearly illustrate the specific embodiments of the present invention, the following briefly introduces the drawings required for use in the embodiments.

[0032] Figure 1 It is a schematic diagram of a QR code-associated error prevention method for finished cigarette products provided by the present invention.

[0033] Figure 2 It is a schematic diagram of a QR code-associated error prevention system for finished cigarette products provided by the present invention. DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings and implementation methods.

[0035] Aiming at the problem that the current sealing of finished cigarette boxes often causes errors in associated information due to blockage, which requires a lot of manpower and material resources to correct the errors, the present invention provides a QR code association error prevention method and system for finished cigarette products, which solves the problem that the sealing of finished cigarette boxes often causes errors in associated information due to blockage, which requires a lot of manpower and material resources to correct the errors. It can prevent errors in associated information of finished cigarette products, improve production management level, and reduce production costs.

[0036] like Figure 1As shown, a QR code-associated error prevention method for finished cigarette products includes:

[0037] S1: A three-push photoelectric device is installed on both sides of the belt conveyor after the second push of the carton sealer to detect smoke on the conveyor belt between the carton sealer and the coding machine.

[0038] S2: When the three-push photoelectric device detects a cigarette case, the cigarette carton sequence value corresponding to the cigarette case in the second-push variable signal is transferred to the third-push variable, so that the second-push variable signal is no longer associated with the cigarette case code of the coding machine.

[0039] S3: A four-push photoelectric device is set in front of the coding position of the coding machine to detect smoke at the coding position of the coding machine.

[0040] S4: When the four-push photoelectric device detects a cigarette carton, the cigarette carton sequence value in the three-push variable signal is transferred to the four-push variable, and the four-push variable is associated with the cigarette carton code printed by the coding machine.

[0041] In actual applications, under normal circumstances, after the carton sealer pushes twice, the carton sequence for cigarette pack 1 is confirmed. When the coding machine codes the carton, the completed carton sequence is associated with the carton code 1 printed by the coding machine. However, if the carton sealer's outlet is blocked, after the carton sealer pushes twice, the carton sequence for cigarette pack 2 is confirmed in the second push variable, overwriting the original carton sequence for cigarette pack 1 in the second push variable. At this time, due to the blockage, cigarette pack 1 on the belt conveyor is still stuck, waiting to be coded. When the coding machine codes cigarette pack 1, the box condition association system will associate the newly confirmed carton sequence for cigarette pack 2 in the second push variable with the cigarette pack 1 printed by the coding machine, resulting in an incorrect association. The cigarette pack code printed by the coding machine can be a QR code.

[0042] This method is based on the actual situation that the belt length in front of the coding machine in the main transmission channel of the carton sealing machine is limited and may be blocked. Therefore, a three-push variable photoelectric signal is added on both sides of the belt conveyor after the second push of the carton sealing machine. When the photoelectric signal detects a cigarette case, regardless of whether it is blocked, the second push variable signal will be passed to the third push variable. The second push variable signal is no longer associated with the cigarette case code of the coding machine, and the cigarette sequence in the new cigarette case can be confirmed. A fourth push photoelectric signal is added at the coding position of the coding machine. When the photoelectric signal detects a cigarette case, regardless of whether it is blocked, the third push variable signal will be passed to the fourth push variable. The fourth push variable is associated with the cigarette case code printed by the coding machine.

[0043] In one embodiment, due to the limited length of the belt in front of the coding machine in the main conveying channel of the carton sealer, which may cause blockage, a three-push photoelectric device is added on both sides of the belt conveyor after the second push of the carton sealer. When a cigarette is detected, regardless of whether there is a blockage, the second push variable signal will transfer the cigarette carton sequence 1 value of the second push variable signal to the third push variable. The second push variable signal is no longer associated with the cigarette carton code printed by the coding machine, and the second push variable signal can be used to confirm the cigarette carton sequence within the new cigarette carton. A fourth push photoelectric device is added before the coding machine's coding position. When a cigarette is detected, the third push variable signal will transfer the cigarette carton sequence 1 value of the third push variable signal to the fourth push variable. Regardless of whether there is a blockage in the main conveying channel of the carton sealer, the fourth push variable is associated with the cigarette carton code printed by the coding machine, and can promptly associate the correct cigarette carton sequence signal within the cigarette carton with the cigarette carton code, preventing incorrect association of cigarette carton.

[0044] The method further comprises: performing a blockage detection on the outlet of the carton sealing machine, and if a blockage exists, re-confirming the cigarette sequence of the second deduction variable signal and the corresponding cigarette pieces.

[0045] The method further comprises: setting a pushing photoelectric device to detect whether the cigarette pieces are pushed into the carton from the conveyor belt and have been arranged neatly.

[0046] The method also includes: setting a second push photoelectric device at the folding station to detect whether the carton is pushed to the folding station. If so, the carton is sealed and the sealing tape is applied, and the serial value of the cigarette carton is confirmed.

[0047] Furthermore, the one-push photoelectric device, the two-push photoelectric device, the three-push photoelectric device and the four-push photoelectric device all use photoelectric sensors.

[0048] It can be seen that the present invention provides a QR code association error prevention method for finished cigarette products. By adding a three-push photoelectric device and a four-push photoelectric device, the cigarette carton sequence value corresponding to the cigarette carton in the two-push variable signal is transferred to the three-push variable. When the four-push photoelectric device detects a cigarette carton, the cigarette carton sequence value in the three-push variable signal is transferred to the four-push variable, and the four-push variable is associated with the cigarette carton code printed by the coding machine, so as to timely associate the correct cigarette carton sequence signal in the cigarette carton with the cigarette carton code. This solves the problem that the existing cigarette carton sealing process often causes association information errors due to blockage, which requires a large amount of manpower and material resources to correct errors. It can prevent errors in association information of finished cigarette products, improve production management level, and reduce production costs.

[0049] Accordingly, if Figure 2As shown, the present invention also provides a two-dimensional code association error prevention system for finished cigarette products, comprising: a controller, a three-push photoelectric device and a four-push photoelectric device; the controller is respectively connected to the carton sealing machine, the coding machine, the three-push photoelectric device and the four-push photoelectric device by signal; the three-push photoelectric device is arranged on both sides of the belt conveyor after the second push of the carton sealing machine to perform cigarette piece detection on the conveyor belt between the carton sealing machine and the coding machine; when the three-push photoelectric device detects a cigarette piece, the controller transfers the cigarette strip sequence value corresponding to the cigarette piece in the two-push variable signal to the three-push variable, so that the two-push variable signal is no longer associated with the cigarette piece code of the coding machine; the four-push photoelectric device is arranged in front of the coding position of the coding machine to perform cigarette piece detection on the coding position of the coding machine; when the four-push photoelectric device detects a cigarette piece, the controller transfers the cigarette strip sequence value in the three-push variable signal to the four-push variable, and associates the four-push variable with the cigarette piece code printed by the coding machine.

[0050] The system also includes: a push photoelectric device; the controller is connected to the push photoelectric device signal, and the push photoelectric device is set at the entrance of the carton sealing machine to detect whether the cigarettes are pushed into the carton from the conveyor belt and have been arranged neatly.

[0051] The system also includes: a two-push photoelectric device; the controller is connected to the two-push photoelectric device by signal, and the two-push photoelectric device is arranged at the folding station of the carton sealing machine to detect whether the carton is pushed to the folding station. If so, the carton is sealed and the tape is applied, and the serial value of the cigarette strips is confirmed.

[0052] The system also includes: a blockage detection device; the controller is connected to the signal of the blockage detection device, and the blockage detection device is arranged at the outlet of the carton sealing machine to detect blockage at the outlet of the carton sealing machine. If there is a blockage, the second deduction variable signal and the corresponding cigarette are re-confirmed in the cigarette sequence.

[0053] Furthermore, the blockage detection device uses a plurality of photoelectric switches, and the controller determines that a blockage occurs when the photoelectric switches are blocked for a time greater than a set threshold.

[0054] It can be seen that the present invention provides a QR code association error prevention system for finished cigarettes. By adding a three-push photoelectric device and a four-push photoelectric device, the cigarette carton sequence value corresponding to the cigarette carton in the two-push variable signal is transferred to the three-push variable. When the four-push photoelectric device detects a cigarette carton, the cigarette carton sequence value in the three-push variable signal is transferred to the four-push variable, and the four-push variable is associated with the cigarette carton code printed by the coding machine, so as to timely associate the correct cigarette carton sequence signal in the cigarette carton with the cigarette carton code. This solves the problem that the existing cigarette carton sealing process often causes association information errors due to blockage, which requires a lot of manpower and material resources to correct errors. It can prevent errors in association information of finished cigarette products, improve production management level, and reduce production costs.
