Description

Technical Field

[0001] The utility model relates to the technical field of cigarette equipment manufacturing, and more specifically, to a two-dimensional code box strip association sequence error prevention device. Background Art

[0002] In the application of QR code association systems, particularly in the cigarette packaging process in the tobacco industry, cigarette refillers, as key components of automated production lines, are responsible for replenishing missing or substandard cigarette packs during the cigarette packaging process to ensure the integrity and standardization of the final product. During this process, each cigarette pack is typically accompanied by a unique QR code that is used to track key data such as product information, production date, and batch number, thereby achieving full product traceability and anti-counterfeiting.

[0003] Because the refill operation must be completed in an extremely short time, and the information transmission and QR code reading processes on the production line need to be rapid and continuous, the QR code information on different small packs of cigarettes may overlap in time or be too close to each other. In this case, if the system fails to properly handle this high-speed and dense information flow, the QR code information of the next small pack of cigarettes may be confused with or overwritten by the information of the previous small pack during the reading or processing process.

[0004] When the QR code information is incorrectly read or overwritten, the association between the small packs of cigarettes and the cigarette rods, which should have been one-to-one, will be disrupted. This will cause the information recorded by the system to be inconsistent with the QR code information on the actual product, thereby creating the illusion of "more or less boxes". In other words, the system believes that multiple small packs of cigarettes have been associated, but in fact only some or no small packs of cigarettes may be correctly associated. This abnormal association not only affects the normal traceability and anti-counterfeiting functions of the product, but may also lead to the accumulation of errors on the production line, affecting overall production efficiency and product quality. Once such problems are discovered, manual intervention is usually required to investigate and correct them, and even the entire batch of products may need to be eliminated for repackaging and testing, which will undoubtedly greatly increase production costs and time consumption. Utility Model Content

[0028] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention.

[0029] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0030] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0031] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0032] In the existing QR code association system application, when the cigarette replenisher on the cigarette packaging machine receives the replenished cigarettes, the QR code of the small box of cigarettes it replenishes is easily covered by the QR code information of other small boxes due to the short phase interval of the other QR code information transmitted after the information transmission is triggered. As a result, after the box strip is associated, it does not match the physical QR code, resulting in the phenomenon of more boxes or less boxes in the box strip association data. The system association is abnormal, and even if it is eliminated in time, it greatly increases the consumption cost. The present application installs an electromagnetic switch trigger device on the cigarette replenisher, and by adjusting the trigger time point, lengthens the phase difference with the information transmission of other code readers, triggers the cigarette replenisher to read the code in time, prevents the small box QR code sequence from being inconsistent with the sequence information in the actual cigarette strip, avoids the occurrence of QR code association abnormalities here, and reduces the occurrence of quality accidents in the production process.

[0033] The utility model proposes an embodiment of a two-dimensional code box strip association sequence error prevention device, specifically, Figure 1 shown, including:

[0034] The small box sequence code reader 1 is installed near the small box cigarette replenishment turntable 10, and is used to read the QR code information on the small box when it passes. The small box sequence code reader 1 is also connected to the QR code association system 6, and sends the read QR code information to the QR code association system 6, and the QR code association system 6 judges the received small box QR code information; wherein, the QR code contains key information such as the unique identification of the small box, production date, batch number, etc.

[0035] The small box detection and rejection mechanism 2 is connected to the packaging machine PLC (programmable logic controller) 7 through a signal line, and the packaging machine PLC7 controls the small box detection and rejection mechanism 2 to perform corresponding rejection operations; when it is detected that the small box QR code information is wrong, missing or does not meet the requirements, the packaging machine PLC7 will send a signal to the rejection mechanism to perform the rejection operation and remove the unqualified small boxes from the production line.

[0036] The small box cigarette replenishment code reader 3 is connected to the QR code association system 6. The small box cigarette replenishment code reader 3 is triggered by the electromagnetic switch 4 to read the QR code information of the newly replenished small box and upload the QR code information of the small box to the QR code association system 6;

[0037] The electromagnetic switch 4 is connected to the small box cigarette replenisher 9 and outputs a signal line to the control end of the small box cigarette replenishment reader 3. When the small box cigarette replenisher 9 replenishes cigarettes, the electromagnetic switch 4 detects the movement of the cigarette replenishment cylinder, triggering the small box cigarette replenishment reader 3 to read the QR code information of the small box, upload it to the QR code association system 6, arrange it in the cigarette sequence, and push it to the small box arrangement belt 11;

[0038] The QR code association system 6 is connected to the packaging machine PLC 7 via a network connection device 8, enabling data exchange with the entire packaging control system. It is also directly connected to the small box sequence reader 1 and the small box replenishment reader 3 to receive the QR code information of the small boxes. The QR code association system 6 verifies, processes, and stores the received QR code information, ensuring that each small box's QR code is correctly associated with the corresponding cigarette carton sequence. Furthermore, the QR code association system 6 monitors the entire packaging process, promptly identifying and addressing any anomalies.

[0039] In an embodiment of the present invention, the QR code box strip association sequence error prevention device also includes a cigarette strip rejection device 5, which is connected to the packaging machine PLC7. The packaging machine PLC7 controls the cigarette strip rejection device 5 to perform corresponding rejection operations. The cigarette strip rejection device 5 is used to detect whether the cigarettes that have been arranged into strips have mismatched, missing or other quality problems in the QR code information, and performs a rejection operation when these problems are found, ensuring that only qualified cigarette strips enter the next stage of the packaging process. The cigarette strip rejection device 5 includes a pneumatic push rod and a conveyor belt. When the packaging machine PLC7 issues a rejection instruction, the pneumatic push rod quickly starts to push the unqualified cigarette strips off the production line, and then the conveyor belt guides them into the collection unit.

[0040] In an embodiment of the present invention, the small box cigarette replenishment turntable 10 is connected to the production line through a mechanical structure and is driven to rotate by a motor. It is used to carry and rotate the small boxes so that the small boxes pass through the small box sequence code reader 1 and the small box cigarette replenishment code reader 3 one by one for code reading. When the production line is started, the motor starts working and drives the small box cigarette replenishment turntable 10 to rotate through the transmission mechanism. When the small box passes through the small box sequence code reader 1, the small box sequence code reader will scan and read the QR code information on the small box, and then send the information to the QR code association system 6 for processing; if replenishment of cigarettes is required, the small box cigarette replenishment code reader 3 will read the QR code information of the newly replenished small box under the triggering of the electromagnetic switch 4, and also send it to the QR code association system 6. The QR code association system 6 judges and processes the received QR code information and feeds the result back to the packaging machine PLC7 so that subsequent rejection or packaging operations can be performed.

[0041] In an embodiment of the present utility model, the QR code box strip association sequence error prevention device also includes a small box arrangement belt 11, which is connected to the production line through a mechanical structure and is used to arrange the small boxes into strips after the cigarettes are replenished and the codes are read. After the QR code information is correctly associated and confirmed to be correct, the small boxes will be pushed onto this belt and arranged into cigarette strips in a predetermined order, ready for subsequent packaging operations. Among them, the small box arrangement belt 11 includes a belt body, a drive motor, a reducer, a transmission device, a belt tensioning device, a belt support frame, etc. The drive motor transmits power to the transmission device through the reducer, thereby driving the belt body to rotate. The belt body runs stably on the support frame, transporting the small boxes from one working area to the working area where they are arranged into strips.

[0042] In an embodiment of the present invention, the small box sequence code reader 1 and the small box smoke replenishment code reader 3 are both installed on a sliding guide rail. The positions of the small box sequence code reader 1 and the small box smoke replenishment code reader 3 are adjusted by sliding the sliding guide rail, thereby changing the relative angle between the scanning area and the small box moving path.

[0043] In an embodiment of the present invention, the small box sequence code reader 1 and the small box smoke replenishment code reader 3 are both installed on a rotating bracket, and the phase angle of the small box sequence code reader 1 and the small box smoke replenishment code reader 3 relative to the small box moving path is adjusted by rotating the bracket.

[0044] By adjusting the phase angles of the small-box sequence reader 1 and the small-box supplementary smoke reader 3 during reading, the QR code is positioned optimally when passing through the small-box sequence reader 1 and the small-box supplementary smoke reader 3, thereby avoiding obstruction by labels or packaging materials on adjacent small boxes. This not only improves code reading accuracy and reliability, but also reduces errors and downtime on the production line, thereby increasing overall production efficiency.

[0045] In this embodiment of the present invention, the QR code box strip association sequence error prevention device also includes an alarm device, which is connected to the packaging machine PLC7 and is an audible and visual alarm. It should be noted that when the QR code box strip association sequence error prevention device detects an abnormality such as incorrect QR code information on the small box, missing small boxes, or incorrect arrangement of small boxes, the packaging machine PLC7 will immediately receive a corresponding error signal. Subsequently, the packaging machine PLC7 determines whether to trigger the alarm device based on pre-set program logic. Once it determines that an alarm is necessary, the packaging machine PLC7 sends an alarm signal to the audible and visual alarm. Upon receiving the signal, the audible and visual alarm immediately activates the alarm mode, emitting an alarm sound and light signal to alert the operator and prompt them to take appropriate measures.

[0046] In this embodiment of the present invention, the network connection device 8 utilizes either a wired or wireless connection, including but not limited to Ethernet, wireless networks (such as Wi-Fi and Bluetooth), and serial communication lines (such as RS-232 and RS-485). The QR code association system 6 is connected to the packaging machine PLC via the network connection device 8, enabling real-time data transmission and immediate command issuance. This real-time data transmission and command issuance ensures a continuous and efficient production process.

[0047] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings, but the above is only a preferred embodiment of the present invention. It should be noted that the technical features involved in the above embodiments and their preferred methods can be reasonably combined and matched into a variety of equivalent schemes by those skilled in the art without departing from or changing the design ideas and technical effects of the present invention; therefore, the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
