Description

Technical Field

[0001] This utility model relates to the field of cigarette pack testing technology, and in particular to a device for detecting the grading label inside a cigarette pack. Background Technology

[0002] The modern tobacco industry generally uses automated purchasing lines for tobacco leaf procurement. The specific process is as follows: Tobacco leaf graders place the selected and sorted tobacco leaves of the same grade into standard tobacco baskets. The chief grader assigns a grade to the corresponding electronic tag (RFID, Radio Frequency Identification) based on the quality of the tobacco leaves in the basket and the grading standard. Driven by the conveyor belt, the graded tobacco baskets reach the automatic weighing sensing area. The weighing computer senses the electronic tag grading and automatically weighs the leaves. The baskets are then conveyed to the packing area, where they are compressed by a hydraulic press to fit into burlap sacks and then sewn together, according to the grade and at a standard of 40 kg / pack. A single automated purchasing line can purchase an average of 260-300 dan (a unit of weight) of tobacco leaves per day, and grade and weigh 1800-2200 baskets of tobacco leaves. In such a high-intensity and high-frequency acquisition process, it is inevitable that RFID grading tags will be mixed in with the cigarette packs. When a grading tag is found to be missing, it is impossible to determine which pack the grading tag is missing from manually. It is necessary to trace and search through many cigarette packs, and even find cigarette packs on the transport vehicle. The search volume is large, which is time-consuming and labor-intensive.

[0003] Since the quality of tobacco leaves is of paramount importance, impurities mixed in with the tobacco leaves, especially those containing plastic components, can not only damage the machine when cutting the tobacco leaves into shreds, but also produce an off-flavor when mixed into cigarettes, seriously damaging the brand image and causing major incidents such as the return of the entire batch of tobacco leaves.

[0030] To make the technical problems, solutions, and advantages of this utility model clearer, a detailed description will be provided below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In addition, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] like Figure 1 As shown, an embodiment of this utility model provides a device for detecting grading labels inside cigarette packs, comprising:

[0033] Power supply module, processing module, communication module, alarm module, cloud management platform, management interface;

[0034] The output terminal of the power module is connected to the power terminals of the processing module and the alarm module; the first data transmission terminal of the processing module is connected to the data transmission terminal of the cloud management platform through the communication module; the second data transmission terminal of the processing module is connected to the data transmission terminal of the external device through the management interface; and the output terminal of the processing module is connected to the input terminal of the alarm module.

[0035] The working principle of this utility model embodiment is as follows:

[0036] The power module provides operating power to the processing module and the alarm module. The processing module sends radio frequency signals to the cigarette packs to be tested. Cigarette packs with grading plates send feedback signals to the processing module based on the radio frequency signals. The processing module sends feedback signals to the cloud management platform through the communication module and sends control signals to the alarm module based on the feedback signals. The alarm module starts working based on the control signals.

[0037] Ideally, the power module is mainly used to supply power to the processing module and alarm module to ensure their normal operation, including the power management unit and lithium battery;

[0038] The output terminal of the lithium battery is connected to the power terminals of the processing module and the alarm module through the power management unit.

[0039] In this embodiment of the utility model, the lithium battery is a rechargeable lithium-ion battery, and the power management unit is a power management chip, which is used to manage the charging and discharging of the lithium battery and voltage protection. When the lithium battery is low on power, an external power source is connected, and the power management chip charges the lithium battery. When the lithium battery is fully charged, the power management chip automatically stops charging to prevent overcharging and damage to the lithium battery.

[0040] In this embodiment of the invention, the power module also includes a power indicator light. During standby use, the power indicator light remains on until the lithium battery is low on power.

[0041] The optimal choice is, such as Figure 2 As shown, the processing module includes a debugging unit, a detection unit, and a recognition unit;

[0042] The first input terminal of the debugging unit is connected to the output terminal of the cloud management platform via a communication module;

[0043] The second input terminal of the debugging unit is connected to the input terminal of an external device through a management interface;

[0044] The output of the debugging unit is connected to the control terminal of the detection unit and the control terminal of the identification unit, respectively.

[0045] The output of the detection unit is connected to the input of the recognition unit;

[0046] The output of the identification unit is connected to the input of the alarm module;

[0047] The data transmission end of the identification unit is connected to the data transmission end of the cloud management platform through a communication module.

[0048] In this embodiment of the utility model, the debugging unit is used to receive configuration parameters issued by the cloud management platform or parameters set by external devices. The configuration parameters include signal detection strength, detection mode, and automatic shutdown time. The parameters set by external devices can be the distance for transmitting video signals. The debugging unit uses the received parameters to debug the detection unit and the identification unit respectively. The detection unit is used to transmit radio frequency signals to the cigarette pack to be detected, receive feedback signals returned by the cigarette pack with the grading plate according to the radio frequency signals, and send feedback signals to the identification unit. The identification unit identifies the distance of the cigarette pack with the grading plate according to the strength of the feedback signal and sends a control signal to the alarm module. It also sends the identification results and alarm information to the cloud management platform through the communication module.

[0049] In this embodiment of the invention, the debugging unit is only used to debug the detection unit and the identification unit using received debugging parameters, similar to a programmer in the prior art; the detection unit can be equivalent to an RF signal transceiver; the identification unit is a conventional central processing unit, which identifies the distance of the cigarette pack with the graded brand based on the strength of the feedback signal and sends a control signal to the alarm module. It also sends the identification information and alarm information to the cloud management platform through the communication module, which are conventional functions of the central processing unit. This embodiment of the invention does not involve any improvement to the software.

[0050] The preferred option is a 4G communication module.

[0051] It should be noted that the 4G communication module used in this embodiment of the present invention is a conventional 4G communication module used in the field for realizing remote communication. This embodiment of the present invention does not involve any improvement to the internal structure of the 4G communication module, so its working principle and internal connection relationship will not be described in detail here.

[0052] Ideally, the alarm module includes an audible and visual alarm unit;

[0053] The input terminal of the audible and visual alarm unit is connected to the output terminal of the recognition unit.

[0054] In this embodiment of the utility model, the sound and light alarm unit includes a buzzer and an indicator light. When the buzzer and the indicator light receive the control signal sent by the identification unit, the buzzer emits an alarm sound and the indicator light flashes synchronously. The stronger the feedback signal, the higher the frequency of the alarm sound emitted by the buzzer and the flashing frequency of the indicator light, thus achieving timely and effective reminders in noisy working conditions.

[0055] Ideally, the management interface includes a USB debugging interface and an output signal control interface;

[0056] The second input terminal of the debugging unit is connected to the input terminal of an external device via a USB debugging interface;

[0057] The output of the identification unit is connected to the control terminal of an external device through an output signal control interface.

[0058] In this embodiment of the invention, without using a 4G communication unit, the parameters of the detection unit can be adjusted via a USB debugging interface. For example, in a confined smoke station, the range of the received feedback signal can be reduced to avoid false alarms; in a spacious smoke station or outdoors, the range of the received feedback signal can be maximized to improve the sensitivity of this embodiment of the invention and avoid missed alarms.

[0059] It should be noted that this utility model embodiment can not only be handheld scanning to confirm the absence of feedback signals before loading and unloading cigarette packs, but it can also be set up at the warehouse entrance to achieve pack-by-pack inspection of cigarette packs entering and leaving the warehouse. It can also be used in conjunction with external devices; for example, the external device is a conveyor belt motor. The output end of the identification unit is connected to the conveyor belt motor through an output signal control interface. When a grading label is mixed into a cigarette pack on the conveyor belt, an audible and visual alarm is triggered, and the identification unit controls the conveyor belt to stop through the output signal control interface, so that quality inspectors can accurately locate the problematic cigarette packs and handle them quickly.

[0060] It should be noted that the cloud management platform is mounted on smart terminal devices and presented as a terminal APP or application. It is used to receive recognition results uploaded by the recognition unit through the communication module, and also to input configuration parameters and operating parameters to the debugging unit to adjust the working mode of the processing module. When used in conjunction with external devices, the cloud management platform can remotely manage them and achieve fully automatic detection. The cloud management platform can also periodically compile alarm information for easy viewing by managers.

[0061] It should be noted that smart terminal devices include, but are not limited to, smartphones, tablets, laptops, or desktop computers.

[0062] This utility model embodiment includes a power module, a processing module, a communication module, an alarm module, a cloud management platform, and a management interface. The power module provides operating power to the processing module, communication module, and alarm module. The processing module sends radio frequency signals to the cigarette packs to be tested. Cigarette packs containing grading labels send feedback signals to the processing module based on the radio frequency signals. The processing module sends feedback signals to the cloud management platform through the communication module and sends control signals to the alarm module based on the feedback signals. The alarm module starts working based on the control signals. Compared with the prior art, using this utility model embodiment eliminates the need to disassemble all cigarette packs for searching. Only scanning the cigarette packs to be tested is needed to find cigarette packs mixed with grading labels, making it convenient to use, saving search time, and improving the search speed.

[0063] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
