Description

Technical Field

[0001] The utility model relates to the technical field of tobacco production equipment, in particular to a small-box cigarette pack loose pack detection status monitoring system. Background Art

[0002] The function of the small box cigarette pack packaging machine is to wrap a layer of transparent film on the outside of the cigarette pack. The packaging quality of the film directly affects the product quality of the small box cigarette pack. In order to ensure product quality, the equipment is equipped with a special test for detecting the quality of film packaging, called bulk package detection (film packaging quality that does not meet the standards is collectively referred to as bulk packages). Bulk package detection can effectively detect the quality of film packaging and achieve rejection. It is an important equipment to ensure product quality. Then it becomes particularly important to ensure that the function of bulk package detection is normal. However, in the actual operation process, there will be situations such as the bulk package detection camera and the bulk package detection controller cannot communicate, the rejection enable switch is turned off, the bulk package detection misses (loose packages are not detected and rejected when they appear), and misrepresentation (qualified products are mistakenly regarded as bulk packages and rejected).

[0003] In the prior art, in order to ensure that the detection camera and the control machine communicate normally and the rejection enable switch is in the on state, it is necessary to arrange personnel to conduct equipment inspections every shift and fill in inspection records. In order to ensure that there are no missed rejections in the loose package detection (loose packages are not detected and rejected when they occur), it is necessary to arrange personnel to verify the effectiveness every shift: manually loosen the film at the hexagonal wheel of the equipment to make loose cigarette packages, and observe whether the loose package detection is detected and rejected. If it is rejected, it is judged to be effective, and if it is not rejected, it is judged to be invalid. In order to ensure that there is no mistaken rejection (qualified products are mistakenly rejected as loose packages), when the equipment operator finds that too many unqualified products are rejected at the rejection port (unqualified products rejected at the rejection port include: loose packages, no pull lines, cigarette package appearance defects, etc.), they can only rely on themselves to judge whether the loose cigarette packages are mistakenly rejected.

[0004] However, the existing technology uses manual monitoring of the bulk package detection status to result in misjudgment, and is unable to efficiently verify the effectiveness of bulk package detection at multiple frequencies, resulting in a waste of manpower and material resources, and is unable to promptly discover detection status problems and ensure product quality in a timely manner. Therefore, it is an important issue to develop a small-box cigarette package bulk package detection status monitoring system to avoid these situations and ensure the effectiveness of the bulk package detection system.

[0021] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0022] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein.

[0023] In the prior art, in order to ensure that the detection camera and the control machine communicate normally and the rejection enable switch is in the on state, it is necessary to arrange personnel to perform equipment inspections in each shift and fill in inspection records. In order to ensure that there are no missed rejections in the bulk package detection, it is necessary to arrange personnel to perform validity verification in each shift: in order to ensure that there are no false rejections, when the equipment operator finds that too many unqualified products are rejected at the rejection port, he or she can only rely on himself or herself to judge whether the bulk cigarette packs are mistakenly rejected. The utility model uses the control machine to make a judgment based on the detection signal transmitted by the first step-down module, and outputs a logic control signal to control the display screen to display in normal mode, abnormal mode, validity verification mode, or rejection reminder mode; when the bulk package detection camera of the bulk package detection device fails to communicate with the bulk package detection controller, the rejection enable switch is turned off, and the bulk package detection is missed or mistakenly rejected, feedback can be given through the display screen and the alarm light to promptly remind the maintenance personnel to handle it.

[0024] The utility model proposes an embodiment of a small cigarette pack loose pack detection status monitoring system, specifically, Figure 1 shown, including:

[0025] a first step-down module, wherein the input pin of the first step-down module is connected to the bulk package detection device and the small-box cigarette packing machine, the bulk package detection device includes a bulk package detection camera and a bulk package detection controller, the bulk package detection camera is communicatively connected to the bulk package detection controller, the first step-down module is used to receive detection signals outputted according to the operation status of the bulk package detection device and the small-box cigarette packing machine, the output pin of the first step-down module is connected to the control machine, and the received detection signals are transmitted to the control machine, the detection signals include a bulk package detection abnormality signal and a bulk package rejection signal outputted by the bulk package detection device, and a film splicing signal outputted by the small-box cigarette packing machine;

[0026] A control machine, the control machine is connected to the first step-down module, the control machine makes a judgment according to the detection signal transmitted by the first step-down module, and outputs a logic control signal, the logic control signal is used to control the display screen to display in a normal mode, or an abnormal mode, or a validity verification mode, or a rejection reminder mode;

[0027] The display screen is connected to the control machine for communication, and the display screen displays different prompting pictures based on the logic control signal.

[0028] Among them, when the scattered packet detection is normal, the display screen displays in normal mode, that is, "camera communication is normal, rejection is enabled normally, and detection function is normal" is displayed with a blue background, and the alarm light goes out.

[0029] When the loose pack detection camera cannot communicate with the loose pack detection controller, the loose pack detection device will no longer collect photos, and the loose pack detection is in an invalid state. When the rejection enable switch is turned off, the loose pack detection device will collect photos, but will not reject loose cigarette packs when they are detected, and the loose pack detection is also in an invalid state. When the above two situations occur, the loose pack detection status monitoring system will identify and feedback, control the alarm light to light up, and the display screen will display in abnormal mode, that is, with a red background, and prompt "Rejection is closed or communication is abnormal, please call maintenance personnel for processing"; when the maintenance personnel handle it normally, the alarm light will go out, and the screen image will return to normal mode display.

[0030] On the other hand, in order to ensure that the loose pack detection is effective and no leakage occurs, a validity verification mode is set, that is, when the film transparent paper is replaced, the film joint (the equipment consumes a roll of film every 40 minutes of normal operation, and the new and old films are bonded together with a soldering iron to produce a joint) is regarded as a loose pack cigarette (the film joint is packaged outside the cigarette package, the packaging quality is poor, and it is regarded as a loose pack defective product). After the film is replaced, the equipment is running. If the loose pack detection device does not detect the loose pack cigarette rejection, it is considered that the loose pack detection is invalid, and the control machine controls the alarm light to light up all the time, the screen is displayed in green, and prompts "Loose pack validity verification, please call maintenance personnel for processing if it fails". Through validity verification, there is no need to arrange personnel to artificially create loose pack cigarettes for verification, the verification frequency is high, and the loose pack cigarettes produced by the joints of the new and old films are more reasonable, and do not occupy equipment production time.

[0031] Furthermore, when loose pack cigarettes are rejected, the control machine of the loose pack detection status monitoring system controls the alarm light to light up for 5 seconds and then go out, and the screen screen displays the message "Loose pack cigarettes are rejected, the frequency is high, please call maintenance personnel to adjust" with a yellow background, and then displays the normal mode screen for 5 seconds; if N packs of loose pack cigarettes are rejected within 1 minute, where N ≥ 8, and N is a positive integer, it means that there are false rejections in the loose pack detection or there are many loose pack cigarettes. At this time, the alarm light comes on, the screen screen displays the message "Loose pack cigarettes are rejected, the frequency is high, please call maintenance personnel to adjust". The utility model can easily distinguish whether the cigarettes rejected by the rejection port are loose pack cigarettes by reminding to reject loose pack cigarettes. It can play a warning role when more loose pack cigarettes are rejected. When there are many false rejections, it can be adjusted in time to reduce the consumption of auxiliary materials. When there are many loose pack cigarettes rejected, it can be handled in time, so as to eliminate quality risks.

[0032] In one embodiment of the utility model, the small box cigarette pack loose pack detection status monitoring system also includes a boost module, which is connected to the control machine, and the control machine is connected to an alarm light through the boost module, and the control machine displays and controls the alarm status of the alarm light through the boost module. Among them, when the display screen displays "camera communication is normal, rejection is normal, and detection function is normal", the alarm light goes out; when the display screen displays "abnormal mode", "validity verification mode", and "rejection reminder mode", the alarm light is on.

[0033] In one embodiment of the utility model, the small-box cigarette pack loose pack detection status monitoring system also includes a second step-down module, and the control machine and the display screen are both connected to the power supply through the second step-down module, and the power supply is a 24V power supply.

[0034] In one embodiment of the utility model, the small-box cigarette bulk pack detection status monitoring system also includes an electric control box, a display screen is embedded in the front surface of the electric control box, an alarm light is fixed on the left surface of the electric control box, a first step-down module, a second step-down module, a step-up module and a control machine are fixed on a plexiglass board and placed in the electric control box; wherein, the electric control box can provide a certain degree of electromagnetic shielding to reduce the impact of external electromagnetic interference on the system; the plexiglass board has good transparency, weather resistance and mechanical strength, and serves as a support plate for these electronic modules, which allows external observation of the internal equipment status and has a certain load-bearing capacity.

[0035] Specifically, the control machine adopts an STM32 single-chip microcomputer; the operating frequency of the STM32 single-chip microcomputer can reach 72MHz, which can meet the needs of various high-performance applications. At the same time, the STM32 single-chip microcomputer has a variety of low-power modes, such as sleep mode, stop mode and standby mode, etc., which can achieve long-term operation in low-power applications. In the utility model, the STM32 single-chip microcomputer controls the output of different logic control signals according to different received detection signals to control the display screen and the alarm light to display in different modes.

[0036] Specifically, the first step-down module is a 24V to 3.3V step-down module, the second step-down module is a 24V to 5V step-down module, and the boost module is a 3.3V to 24V boost module. The step-down module and the boost module in the utility model jointly realize the voltage conversion function, ensuring that the system can operate stably under different voltage environments.

[0037] The utility model also proposes an embodiment of a method for monitoring the detection status of a small cigarette pack, specifically as follows: Figure 2 shown, including:

[0038] Receive detection signals for the operation status of the bulk package detection device and the small box cigarette packing machine, and transmit the received detection signals to the control machine, the detection signals include the bulk package detection abnormality signal and the bulk package rejection signal output by the bulk package detection device and the film splicing signal output by the small box cigarette packing machine, wherein the bulk package detection device includes a bulk package detection camera and a bulk package detection controller, when the communication between the bulk package detection camera and the bulk package detection controller is interrupted or the rejection enable switch is turned off, the bulk package detection is determined to be abnormal; wherein the small box cigarette packing machine is a FOCKE401 film small box cigarette packing machine;

[0039] The control machine makes judgments based on the detection signals and outputs logic control signals, which are used to control the display screen and the alarm light to display in different modes;

[0040] Based on the logic control signal output by the control machine, the display is controlled to display in normal mode, abnormal mode, validity verification mode, or rejection reminder mode, and the alarm light is controlled to light up or go out.

[0041] Specifically, the process in which the control machine makes a judgment based on the detection signal and outputs a logic control signal includes:

[0042] When the loose package detection camera of the loose package detection device communicates normally with the loose package detection controller, and the rejection enable switch is turned on, the loose package detection is determined to be normal. At this time, the control machine sends a command to the display screen through the serial port to make the display screen display "camera communication is normal, rejection enable is normal, and detection function is normal" with a blue background, and the alarm light goes out;

[0043] When the communication between the bulk packet detection camera and the bulk packet detection controller of the bulk packet detection device is interrupted, or the rejection enable switch is turned off, the first boost module will obtain a high level, and the bulk packet detection is judged to be abnormal. At this time, the control machine sends a command to the display screen through the serial port to make the display screen display "Rejection is closed or communication is abnormal, please call maintenance personnel for processing" with a red background, and the alarm light is on; when the high level turns to a low level, it is judged that the bulk packet detection is normal.

[0044] Specifically, the process in which the control machine makes a judgment based on the detection signal and outputs a logic control signal also includes:

[0045] After receiving the film splicing detection signal, the control machine sends a command to the display screen through the serial port to make the display screen display "Loose package validity verification, if it fails, please call maintenance personnel for processing" with a green background, and shift. When it shifts to the rejection position, if a loose package rejection signal is received, a command is sent to make the display screen display "Camera communication is normal, rejection is normal, and detection function is normal" with a blue background. If no loose package rejection signal is received, the display screen will continue to display "Loose package validity verification, if it fails, please call maintenance personnel for processing" with a green background. By performing loose package validity verification, there is no need to arrange personnel to artificially create loose package smoke for verification. The verification frequency is high, and the loose package smoke generated by the splicing joints of the new and old films is more reasonable, and it does not occupy the production time of the equipment;

[0046] Specifically, the process in which the control machine makes a judgment based on the detection signal and outputs a logic control signal also includes:

[0047] When loose cigarettes are rejected, the controller sends a command to the display screen through the serial port, so that the display screen displays "loose cigarettes are rejected, the frequency is high, please call maintenance personnel for adjustment" with a yellow background, the alarm light turns on for 5 seconds and then goes out, and the display screen displays in yellow for 5 seconds and then displays "camera communication is normal, rejection is normal, and detection function is normal";

[0048] If the control machine receives N loose pack rejection signals within 1 minute, where N ≥ 8 and N is a positive integer, the display screen will continue to display "Loose pack cigarettes are rejected. If the frequency is high, please call maintenance personnel for adjustment" with a yellow background. Specifically, if the control machine receives 10 loose pack rejection signals within 1 minute, the display screen will continue to display the above with a yellow background.

[0049] The small-box cigarette loose package detection status monitoring system and method of the utility model embodiment can ensure the abnormal monitoring of the small-box cigarette loose package detection status in real time, can automatically verify the effectiveness of the small-box cigarette loose package detection at multiple frequencies, save manpower and material resources, can judge that the loose packages are mistakenly rejected when there are many loose packages rejected to reduce consumption, and can timely discover when they are judged to be loose packages to ensure product quality. It avoids the situation that there will be misjudgment when using manual monitoring of the loose package detection status, and it is impossible to efficiently verify the effectiveness of the loose package detection at multiple frequencies, waste manpower and material resources, and fail to discover the detection status in time.

[0050] 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 concept and technical effects of the present invention; therefore, the present invention is not limited to the scope of implementation as shown in the drawings, and all 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 specification and drawings, should be within the protection scope of the present invention.
