[0002] In the modern tobacco manufacturing industry, cigarette making machines are directly related to the quality and production efficiency of cigarette products. The detection of the joints between the cigarette paper and the tipping paper is a key link in the cigarette making process that is prone to problems. After long-term use, the aging of the cigarette making machine or the influence of dust on the detection head may cause detection failure, so that defective cigarettes with paper joints are not discovered in time and flow into the downstream production links, causing quality problems.

[0018] Embodiment 1

[0019] Figure 1 This is a schematic diagram of a failure detection system for a paper joint detection device of a cigarette making machine provided in the first embodiment of the present invention. This embodiment is applicable to the case where the function effectiveness detection of the paper joint detection device of a cigarette making machine is performed. Figure 1 As shown, the system includes:

[0020] A cigarette making machine paper material electric cabinet 110 for controlling the conveying of target paper material, a paper joint detection device 120 for detecting joints of target paper material, and a controller 130, wherein the controller 130 is electrically connected to the paper joint detection device 120, and the controller 130 is connected to the cigarette making machine paper material electric cabinet 110 to form an auxiliary detection circuit;

[0021] The paper joint detection device 120 is used to detect that the cigarette making machine is changing and splicing the target paper material during the operation of the cigarette making machine, and to generate a paper joint detection signal for the target paper material and send it to the controller 130;

[0022] The controller 130 is used to control the cigarette making machine to reject cigarettes with joints when a paper joint detection signal is detected, and to start a timer for timing when a joint detection signal is detected through an auxiliary detection circuit, and to determine that the paper joint detection device 120 has failed when no paper joint detection signal for the target paper material is received from the paper joint detection device 120 at the end of the timing.

[0023] In the embodiment of the present invention, the target paper material can be specifically understood as: the material used in the cigarette production process, such as cigarette paper used to wrap cigarettes and tipping paper used for filters. The cigarette making machine paper material electrical cabinet can be specifically understood as: an electrical control cabinet that controls the speed, tension and conveying position of the cigarette making machine paper material, which can be composed of a motor driver, a sensor and a control circuit. The paper joint detection device can be specifically understood as: a device for detecting paper material joints (such as the joints of cigarette paper or tipping paper), which is generally installed at the paper joint to be detected in the electrical cabinet. Among them, the paper joint detection device can include two parts: a paper change signal generation module and a joint detection module.

[0024] The paper change signal generation module is used to generate a paper joint detection signal when a roll of paper is used up and needs to be replaced with a new paper roll. This detection signal is the beginning of the joint detection process and is responsible for notifying the controller to start detecting whether the target paper has a joint. The signal can be manually triggered or automatically generated. For example, when a paper material replacement operation is required, the operator can manually press a button to generate a signal, or the equipment can be designed to automatically generate a signal when the end of the paper roll is detected. The joint detection module is used to actually detect the joints on the paper material and send a paper joint detection signal to the controller when the joint is detected. The joint detection module can include a photoelectric sensor or a visual detection system (such as a camera and a corresponding image processing device) to detect whether the position, shape and quality of the paper joint meet the requirements.

[0025] The controller can be specifically understood as: a central processing unit for controlling and managing the entire detection system, generally including a central processing unit, an input / output module and a communication interface, etc., and can be a controller such as a programmable controller or an industrial computer, which is used to receive signals from the paper joint detection device, and perform logical judgments based on these signals, execute control algorithms and send control instructions. The controller is electrically connected to the paper joint detection device (i.e., connected through wires, electrical interfaces, terminals or connectors, etc.), and is connected to the cigarette machine paper material electrical cabinet to form an auxiliary detection circuit for detection and control when necessary.

[0026] The auxiliary detection circuit can be specifically understood as: a circuit that can provide additional detection signals, which are used to detect and diagnose the operating status of the main control circuit or equipment. Among them, the detection signal can include a joint detection signal used to assist the joint detection process and ensure the normal operation of the joint detection device. These signals can be generated by different sensors or detection devices, including: indicating the position of the paper material on the production line to ensure that the joint detection is performed at the correct position. The position signal; the status signal indicating the working status of the joint detection device, for example, reflecting whether the sensor is clean and aligned, etc.; the quality signal indicating the quality level of the joint, for example, the flatness and bonding strength of the joint, etc.

[0027] Specifically, when the paper joint detection device 120 detects that the paper material needs to be spliced ​​during the operation of the cigarette making machine, for example, when a roll of paper material is used up and paper needs to be replaced, it will generate a detection signal and send it to the controller 130. After receiving the paper joint detection signal, the controller 130 performs corresponding control actions, which may include controlling the cigarette making machine to reject cigarettes with joints to ensure product quality, and starting a timer when the joint detection signal is detected by the auxiliary detection circuit.

[0028] If the controller 130 receives the detection signal from the paper joint detection device 120 again before the timing ends, it means that the paper joint detection device 120 is normal. If the controller 130 does not receive the detection signal from the paper joint detection device 120 again at the end of the timing, the controller 130 will determine that the paper joint detection device 120 has failed. For example, the paper joint detection device 120 may not detect the joint correctly, or it may detect the joint but fail to send a signal, or the signal sent by the paper joint detection device 120 may not be successfully transmitted to the controller 130 due to connection problems, interference or other communication failures, or there is a problem with the paper material, which causes the paper joint detection device 120 to be unable to correctly detect the joint, or the detection result will not trigger the operation of sending the detection signal. This indicates that the cigarette machine paper joint detection device 120 has failed, and corresponding measures can be taken, such as sounding an alarm, stopping the production line, switching to a backup detection system or switching to a backup production process, and maintaining the cigarette machine paper joint detection device 120.

[0029] Among them, the setting duration of the timer comprehensively considers the response time of the paper joint detection device 120, the unit production plan, the safety margin, and the reasonable estimation based on historical data and experience. For example, the timing duration needs to be sufficient for the paper joint detection device 120 to complete the detection of the joint, the issuance of the detection signal, and the transmission of the detection signal to the controller; the unit production plan of the cigarette machine, that is, the time required for the equipment to complete a production cycle, the timing duration needs to match the unit production plan to ensure that the detection is completed before the next production cycle begins; because the signal may be delayed during the transmission process, the timing duration can be set with a certain safety margin, that is, slightly longer than the actual maximum time required, to ensure the reliability of the detection system; and based on historical operation data and experience, the distribution of the detection device response time and the corresponding detection accuracy can be identified, so as to determine a reasonable timing duration, while ensuring production efficiency, while ensuring the reliability of the detection device.

[0030] The failure detection system for the paper joint detection device of the cigarette making machine of the embodiment of the present invention comprises: a paper joint detection device for the cigarette making machine for conveying and controlling the target paper material, a paper joint detection device for detecting the joint of the target paper material, and a controller, wherein the controller is electrically connected to the paper joint detection device, and the controller and the paper joint detection device for the cigarette making machine are connected to form an auxiliary detection circuit; the paper joint detection device is used to detect that the cigarette making machine changes and splices the target paper material during the working process of the cigarette making machine, and generate a paper joint detection signal for the target paper material and send it to the controller; the controller is used to control the cigarette making machine to remove cigarettes with joints when the paper joint detection signal is detected through the auxiliary detection circuit, and start the timer for timing when the joint detection signal is detected through the auxiliary detection circuit, and determine that the paper joint detection device is failed when the paper joint detection signal for the target paper material sent by the paper joint detection device is not received at the end of the timing. Through this system, the paper joint detection is automated, the labor cost is reduced, the detection efficiency is improved, the consumption of cigarettes during the test process is reduced, the production cost is reduced, the maintenance process of the cigarette making machine is optimized, and the quality and stability of cigarette production are improved.

[0031] Optionally, based on the above embodiments, the controller is a programmable controller;

[0032] The input pin of the programmable controller is used to be electrically connected to at least one paper joint detection device, and is connected to at least one cigarette making machine paper material electrical cabinet to form an auxiliary detection loop;

[0033] The output pin of the programmable controller is used to be connected to the first failure alarm device and / or the second failure alarm device.

[0034] In the embodiment of the present invention, the failure alarm device can be specifically understood as: a specific alarm device in the detection system, which is used to indicate whether the detection device of different types of paper materials (such as cigarette paper, tipping paper or other types of paper materials) has failed. Among them, the first and second are used to distinguish different failure alarm devices, regardless of the order of precedence. Each failure alarm device may include one or more components, such as: a failure alarm light, which is used to light up when the detection device fails to provide a visual alarm; a buzzer or speaker, which is used to issue a sound alarm to alert the operator; and a display screen or indicator, which is used to show which specific detection device has failed and the possible cause of the failure.

[0035] Specifically, a programmable logic controller (PLC) controls the operation of a failure detection system of a paper joint detection device of a cigarette making machine according to a program written by a user. The input pins of the PLC are used to receive signals from various sensors and detection devices, and need to be electrically connected to a paper joint detection device (a device for detecting cigarette paper or cork paper joints). At the same time, it also needs to be connected to a paper material electrical cabinet of the cigarette making machine to form an auxiliary detection circuit for monitoring the paper joint detection signal sent by the paper material electrical cabinet when paper replacement is required, and starting a timer to monitor the paper joint detection signal sent by the paper joint detection device when a paper joint is detected according to a set duration.

[0036] The output pins of the PLC are used to control various actuators, such as alarm devices, relays and other control modules. Typically, the output pin can be connected to at least one of the first failure alarm device and the second failure alarm device. When the failure of the paper joint detection device is detected, the corresponding device will be triggered to remind the operator to check or repair. The control method of the PLC allows the system to adjust the input and output methods according to different production needs to adapt to the changing production environment. The centralized control of the PLC and the corresponding alarm system simplify the monitoring and management of the production process, facilitate the collection and analysis of production data, and further realize the automation of paper joint detection, reduce labor costs, improve detection efficiency, reduce the consumption of cigarettes during the test process, reduce production costs, optimize the maintenance process of the cigarette machine, and improve the quality and stability of cigarette production.

[0037] Embodiment 2

[0038] Figure 2Another structural schematic diagram of a failure detection system for a paper material joint detection device of a cigarette making machine provided in Example 2 of the present invention. This embodiment is a refinement of the cigarette making machine paper material electric cabinet and the paper joint detection device in the above-mentioned embodiment, specifically including: the cigarette making machine paper material electric cabinet includes a cigarette making machine paper electric cabinet for controlling the conveying of paper rolls, and the paper joint detection device includes a paper roll joint detection device for detecting joints of paper rolls; the controller is connected to the cigarette making machine paper electric cabinet to form a paper roll splicing signal detection circuit.

[0039] Correspondingly, such as Figure 2 As shown, the system includes:

[0040] A cigarette making machine paper cabinet 210 for controlling the conveying of paper, a paper joint detection device 220 for detecting the joints of paper, and a controller 230, wherein the controller 230 is electrically connected to the paper joint detection device 220, and the controller 230 is connected to the cigarette making machine paper cabinet 210 to form an auxiliary detection circuit;

[0041] The paper joint detection device 220 is used to detect when the cigarette making machine is changing and splicing the paper during the operation of the cigarette making machine, and to generate a paper joint detection signal for the paper and send it to the controller 230;

[0042] The controller 230 is used to control the cigarette making machine to remove cigarettes with joints when a paper joint detection signal is detected, and to start a timer for timing when a joint detection signal is detected through an auxiliary detection circuit, and to determine that the paper joint detection device 220 has failed when no paper joint detection signal for the paper is received from the paper joint detection device 220 at the end of the timing.

[0043] In the embodiment of the present invention, the rolling paper refers to the paper used to wrap the tobacco to form a cigarette, which provides physical structural support for the cigarette and directly affects the appearance and feel of the final product. In the process of using the rolling paper for rolling, the cigarette machine needs to detect the joint of the rolling paper to ensure that the rolling paper has sufficient toughness to avoid cracking under the condition of high-speed rolling, and has sufficient uniformity to ensure the consistency and quality of the cigarette. The rolling paper electric cabinet of the cigarette machine can be specifically understood as: responsible for the tension control and position control of the rolling paper and other operations to ensure that the rolling paper can be smoothly and accurately transported to the cigarette position. The rolling paper joint detection device can be specifically understood as: a device for detecting the rolling paper joint, which also includes a device for generating a paper joint detection signal for the rolling paper when the rolling paper is used up and needs to be replaced with a new rolling paper, and when the rolling paper is used up and needs to be replaced, the device can detect the splicing point (i.e., the joint) between the old rolling paper and the new rolling paper, and generate a paper joint detection signal for the rolling paper when the joint is detected. The controller can be specifically understood as a device that is responsible for receiving signals from the paper joint detection device and performing logical judgment and issuing control instructions based on these signals. Specifically, it can be a PLC or an industrial computer. The controller is electrically connected to the paper joint detection device and is connected to the cigarette machine paper electrical cabinet to form an auxiliary detection circuit for additional detection and control when necessary.

[0044] Specifically, during the operation of the cigarette making machine, when it is detected that the cigarette making machine is changing and splicing the paper, the paper joint detection device 220 will generate a paper joint detection signal for the paper and send it to the controller 230. When the controller 230 detects the paper joint detection signal, it will control the cigarette making machine to remove cigarettes with joints to ensure product quality. At the same time, when the controller 230 detects the joint detection signal through the auxiliary detection circuit, it will start the timer for timing. If the paper joint detection signal for the paper sent by the paper joint detection device 220 is not received at the end of the timing, the controller will determine that the paper joint detection device 220 has failed, and can take corresponding measures, such as issuing an alarm or adjusting the production process. Similarly, the preset timing duration of the timer can be set according to actual production needs.

[0045] In a specific example, when the cigarette machine model is a ZJ17 cigarette machine and the controller is a Siemens S7-200SMARTPLC, the detection system detects the paper joint detection device, that is, it detects the function of the joint detection device of the SE electrical cabinet in the ZJ17 cigarette machine. Among them, the ZJ17 cigarette machine includes a MAX electrical cabinet and a SE electrical cabinet, which contain various electrical components and wiring terminals. The MAX electrical cabinet is the electrical control cabinet responsible for the cigarette connecting part of the cigarette machine, which is responsible for connecting cigarettes and filters to form a complete cigarette product; the SE electrical cabinet is the electrical control cabinet responsible for the cigarette rolling part of the cigarette machine, which is responsible for rolling tobacco into cigarettes and cutting them into specified lengths.

[0046] Accordingly, a Siemens S7-200 SMART is installed in the ZJ17 cigarette making machine. PLC, PLC is powered by a positive 24 volt voltage line and a negative 24 volt voltage line, and the input port I0.0 of the PLC is connected to the normally open contact of the A40 relay in the SE cabinet of the ZJ17 cigarette making machine to collect the paper splicing and paper changing signal of the SE cabinet, and the input port I0.2 of the PLC is connected to the No. 6 pin of the X24 terminal in the SE cabinet of the ZJ17 cigarette making machine to collect the SE paper joint detection B14 output signal. The X24 terminal is a terminal block in the SE cabinet for connecting various signal lines. The No. 6 pin is the sixth connection point in the X24 terminal block. When a paper joint is detected, the B14 detector will output a signal and transmit it to the controller (such as the PLC) so that the detection system can perform corresponding processing according to the signal, such as automatically cutting off the joint part to ensure the quality of the cigarette, and starting the timer for timing. Whether the paper joint detection signal of the paper is received by the paper joint detection device at the end of the timing is used to determine whether the paper joint detection device is invalid. Among them, the wiring terminals and pins in the electrical cabinet are determined by the internal wiring of the equipment. The selection of terminals and pins is related to the cigarette making machine model, so the selected connection method is fixed, while the input terminals of the PLC can be adjusted and designed according to specific application requirements.

[0047] The failure detection system of the paper joint detection device of the cigarette making machine of the embodiment of the present invention comprises: a cigarette making machine paper electrical cabinet for controlling the conveying of paper, a paper joint detection device for detecting the joint of paper, and a controller, wherein the controller is electrically connected to the paper joint detection device, and the controller and the cigarette making machine paper electrical cabinet are connected to form an auxiliary detection circuit; the paper joint detection device is used to detect that the cigarette making machine is changing and splicing paper during the working process of the cigarette making machine, and generate a paper joint detection signal for the paper and send it to the controller; the controller is used to control the cigarette making machine to reject cigarettes with joints when the paper joint detection signal is detected through the auxiliary detection circuit, and start the timer for timing when the joint detection signal is detected through the auxiliary detection circuit, and determine that the paper joint detection device is failed when the paper joint detection signal for the paper is not received from the paper joint detection device at the end of the timing. Through the system, the paper joint detection is automated, the labor cost is reduced, the detection efficiency is improved, the consumption of cigarettes during the test process is reduced, the production cost is reduced, the maintenance process of the cigarette making machine is optimized, and the quality and stability of cigarette production are improved.

[0048] Optionally, based on the above embodiments, the paper roll joint detection device is a photoelectric detection device, and the paper roll joint detection device includes: a first transmitting end device and a first receiving end device;

[0049] In the thickness extension direction of the roll paper, the first transmitting end device and the first receiving end device are respectively arranged at two ends of the roll paper, and are used to measure the thickness of the roll paper in real time by means of photoelectric detection, and generate a roll paper joint detection signal according to the real-time measurement result;

[0050] The controller is connected to the normally open contact of the first relay in the cigarette machine paper material cabinet. The first relay is used to perform a relay closing operation when the cigarette machine paper material cabinet triggers a paper changing and splicing action to transmit a paper splicing signal to the controller.

[0051] In the embodiment of the present invention, the photoelectric detection device refers to a device that uses a light beam and a photoelectric sensor to detect the state of an object, and generally includes a transmitting end device and a receiving end device. The first transmitting end device can be specifically understood as: a light source emitting device, such as an LED or a laser diode, etc., the light (visible light or invisible light) emitted by it passes through or reflects through the detected object (such as a roll of paper) and is received by the first receiving end device. The first receiving end device can be specifically understood as: a light receiving device (such as a photoelectric sensor), including a photodiode or a phototransistor, etc., which receives the light reflected from the roll of paper and judges the thickness of the roll of paper and the existence of the joint according to the intensity of the received light. The first relay can be specifically understood as: when the roll of paper is used up and the roll of paper needs to be replaced and spliced, the normally open contact will trigger the closed relay, so that the controller can receive the signal of the roll of paper replacement and splicing, and then the controller can perform the corresponding logical operation.

[0052] Specifically, the system can measure the thickness of the paper roll in real time by means of photoelectric detection. When the paper roll joint (i.e., the connection between the new and old paper rolls) passes, the thickness changes, and the light intensity changes detected by the receiving device will change accordingly. According to the real-time measurement results, the system generates a detection signal to indicate the existence of the joint. The controller is connected to the normally open contact of the first relay in the paper material cabinet of the cigarette machine. The normally open contact of the first relay is closed when the paper change splicing action is triggered, thereby transmitting the paper change signal to the controller. The paper roll joint is monitored in real time by a photoelectric detection device, and an automatic control system is formed in conjunction with the controller to improve the detection accuracy and automation level of the paper roll joint of the cigarette machine, improve production efficiency and product quality, avoid production interruptions caused by paper roll joint problems, reduce material waste, save costs, optimize the maintenance process of the cigarette machine, and improve the quality and stability of cigarette production.

[0053] Optionally, based on the above embodiments, the failure detection system further includes: a first failure alarm device, the first failure alarm device being electrically connected to the controller;

[0054] The controller is also used for: when it is determined that the paper roll joint detection device fails, sending a trigger signal to the first failure alarm device to control the first failure alarm device to perform a failure alarm.

[0055] In the embodiment of the present invention, the failure detection system includes at least one failure alarm device. The first failure alarm device can be specifically understood as: when a failure or failure of the paper roll joint detection device is detected, an alarm signal is issued to notify the operator or the automatic control system. Specifically, it can be an audible and visual alarm (used to emit sound and prompt light), an indicator light (lit up or changed color, such as from green to red), a display screen alarm (displaying alarm information on the human-machine interface, providing more detailed fault information) and a network alarm (sending alarm information to the remote monitoring system or the mobile device of the maintenance personnel through the network for remote maintenance). The installation location of the failure alarm device should ensure that the operator can quickly and clearly see the alarm signal so as to respond in time, for example: on the console, on the button panel, near the emergency stop button, and on the central monitoring system and the operator's mobile device to achieve remote alarm notification.

[0056] Specifically, the first failure alarm device is electrically connected to the controller to receive a trigger signal from the controller. When the controller determines through logical judgment that the detection device has failed (for example, the detection signal is not received within the expected time), the controller sends a trigger signal to the first failure alarm device, activates the first failure alarm device and performs its alarm function, such as making a sound or lighting a warning light, thereby notifying the operator to take necessary maintenance or adjustment measures to ensure the normal operation of the production line or troubleshooting, thereby realizing real-time automatic monitoring of the status of the paper joint detection device. The immediate alarm mechanism greatly improves the reliability and response speed of the system, helps operators quickly identify and deal with problems, thereby reducing production interruptions and material waste, optimizing the maintenance process of cigarette machines, and improving the quality and stability of cigarette production.

[0057] Optionally, based on the above embodiments, the first failure alarm device is a failure alarm light, and the failure alarm light is arranged on the paper roll button panel.

[0058] Specifically, the first failure alarm device can be a failure alarm light, and it is set on the paper roll button panel, so that the operator can intuitively identify the status of the paper roll joint detection device quickly through the light signal, and can see the alarm information at a glance no matter where on the production line, and by setting the alarm light on the button panel, the operator can immediately notice the alarm signal during daily operations, thereby responding quickly, reducing production delays, improving production efficiency, optimizing the maintenance process of the cigarette machine, and improving the quality and stability of cigarette production.

[0059] In a specific example, when the cigarette machine model is ZJ17 cigarette machine and the controller is Siemens S7-200SMARTPLC, an alarm lamp H1 is installed on the paper roll button panel, the output point Q0.1 of the PLC is connected to the A1 foot of the connector detection failure alarm lamp H1 of the SE electric cabinet, and the A2 foot of the alarm lamp H1 is connected to the negative 24 volt power line for power supply. Among them, the output terminal of the PLC can be adjusted and designed according to specific application requirements.

[0064] The tipping paper joint detection device 320 is used to detect when the cigarette making machine is changing and splicing the tipping paper during the operation of the cigarette making machine, and to generate a tipping paper joint detection signal and send it to the controller 330;

[0065] The controller 330 is used to control the cigarette making machine to remove cigarettes with joints when a paper joint detection signal is detected, and to start a timer for timing when a joint detection signal is detected through an auxiliary detection circuit, and to determine that the tipping paper joint detection device 320 has failed when no paper joint detection signal for the tipping paper is received from the tipping paper joint detection device 320 at the end of the timing.

[0066] In the embodiment of the present invention, tipping paper refers to the wrapping material of the cigarette filter. In the process of using tipping paper for rolling, the cigarette machine needs to detect the joint of the tipping paper to ensure that the tipping paper has sufficient toughness to avoid cracking under the condition of high-speed rolling, and has sufficient uniformity to ensure the consistency and quality of the cigarette. The tipping paper electrical cabinet of the cigarette machine can be specifically understood as: an electrical control cabinet responsible for operations such as tension control and position control of the tipping paper to ensure that the tipping paper can be smoothly and accurately transported to the cigarette rolling position. The tipping paper joint detection device can be specifically understood as: a device for detecting the tipping paper joint, which also includes a device for generating a paper joint detection signal for the tipping paper when the tipping paper is used up and needs to be replaced with a new tipping paper, and when the tipping paper is used up and needs to be replaced, the device can detect the splicing point (i.e., the joint) between the old tipping paper and the new tipping paper, and generate a paper joint detection signal for the tipping paper when the joint is detected. The controller can be specifically understood as a device that is responsible for receiving signals from the tipping paper joint detection device and performing logical judgment and issuing control instructions based on these signals. Specifically, it can be a PLC or an industrial computer. The controller is electrically connected to the tipping paper joint detection device and connected to the cigarette machine tipping paper electrical cabinet to form an auxiliary detection circuit for additional detection and control when needed.

[0067] Specifically, during the operation of the cigarette making machine, when it is detected that the cigarette making machine is changing and splicing the tipping paper, the tipping paper joint detection device 320 will generate a paper joint detection signal for the tipping paper and send it to the controller 330. When the controller 330 detects the paper joint detection signal, it will control the cigarette making machine to remove cigarettes with joints to ensure product quality. At the same time, when the controller 330 detects the joint detection signal through the auxiliary detection circuit, it will start the timer for timing. If the paper joint detection signal for the tipping paper sent by the tipping paper joint detection device 320 is not received at the end of the timing, the controller will determine that the tipping paper joint detection device 320 has failed, and can take corresponding measures, such as issuing an alarm or adjusting the production process. Similarly, the preset timing duration of the timer can be set according to actual production needs.

[0068] In a specific example, when the cigarette making machine model is a ZJ17 cigarette making machine and the controller is a Siemens S7-200SMARTPLC, the detection system detects the tipping paper joint detection device, that is, it detects the function of the joint detection device of the MAX electric cabinet in the ZJ17 cigarette making machine.

[0069] Correspondingly, a Siemens S7-200 SMART PLC is installed in the ZJ17 cigarette making machine. The PLC is powered by a positive 24 volt voltage line and a negative 24 volt voltage line. I0.1 is connected to the normally open contact of the A22 relay in the MAX electrical cabinet of the ZJ17 cigarette making machine to collect the MAX tipping paper splicing and paper changing signal. I0.3 is connected to pin 62 of the X9 terminal in the MAX electrical cabinet of the ZJ17 cigarette making machine to collect the MAX tipping paper joint detection B15.3 output signal. The X9 terminal block is a terminal block in the MAX electrical cabinet, which is used to connect various signal lines. Pin 62 is the 62nd connection point in the X9 terminal block. When a tipping paper joint is detected, the B15.3 detector will output a signal and transmit it to the controller (such as PLC) so that the detection system can perform corresponding processing based on this signal, such as automatically cutting off the joint part to ensure the quality of cigarettes, and starting the timer for timing. According to whether the tipping paper joint detection device receives the tipping paper paper joint detection signal sent by the tipping paper joint detection device at the end of the timing, it can be judged whether the tipping paper joint detection device fails. Among them, the terminals and pins in the electrical cabinet are determined by the internal wiring of the equipment. The selection of the terminals and pins is related to the cigarette machine model, so the selected connection method is fixed, and the input terminals of the PLC can be adjusted and designed according to specific application requirements.

[0070] The failure detection system of the paper joint detection device of the cigarette making machine according to the embodiment of the present invention comprises: a tipping paper electrical cabinet for the cigarette making machine for controlling the conveying of tipping paper, a tipping paper joint detection device for detecting the joints of the tipping paper, and a controller, wherein the controller is electrically connected to the tipping paper joint detection device, and the controller and the tipping paper electrical cabinet for the cigarette making machine are connected to form an auxiliary detection circuit; the tipping paper joint detection device is used to generate a paper joint detection signal for the tipping paper and send it to the controller when detecting that the cigarette making machine is changing and splicing the tipping paper during the operation of the cigarette making machine; the controller is used to control the cigarette making machine to remove cigarettes with joints when the paper joint detection signal is detected, and to start a timer for timing when the joint detection signal is detected through the auxiliary detection circuit, and determine that the tipping paper joint detection device has failed when the paper joint detection signal for the tipping paper sent by the tipping paper joint detection device is not received at the end of the timing. This system can automate the detection of tipping paper joints, reduce labor costs, improve detection efficiency, reduce the consumption of cigarettes during the test process, reduce production costs, optimize the maintenance process of cigarette making machines, and improve the quality and stability of cigarette production.

[0071] Optionally, based on the above embodiments, the tipping paper joint detection device is a photoelectric detection device, and the tipping paper joint detection device includes: a second transmitting end device and a second receiving end device;

[0072] In the thickness extension direction of the tipping paper, the second transmitting end device and the second receiving end device are respectively arranged at the two ends of the tipping paper, and are used to measure the thickness of the tipping paper in real time by means of photoelectric detection, and generate a tipping paper joint detection signal according to the real-time measurement result;

[0073] The controller is connected to the normally open contact of the second relay in the cigarette machine paper material cabinet. The second relay is used to perform a relay closing operation when the cigarette machine paper material cabinet triggers a paper changing and splicing action to transmit the tipping paper splicing signal to the controller.

[0074] In the embodiment of the present invention, the second transmitting-end device can be specifically understood as: a light source emitting device, such as an LED or a laser diode, etc., the light (visible light or invisible light) emitted by it passes through or reflects through the detected object (such as tipping paper) and is received by the second receiving-end device. The second receiving-end device can be specifically understood as: a light receiving device (such as a photoelectric sensor), including a photodiode or a phototransistor, etc., which receives the light reflected from the tipping paper and judges the thickness of the tipping paper and the existence of the joint according to the intensity of the received light. The second relay can be specifically understood as: when the tipping paper is used up and the tipping paper needs to be replaced and spliced, the normally open contact will trigger the closed relay, so that the controller can receive the signal of the tipping paper replacement and splicing, and then the controller can perform the corresponding logical operation.

[0075] Specifically, the system can measure the thickness of the tipping paper in real time by means of photoelectric detection. When the tipping paper joint (i.e., the connection between the new and old tipping papers) passes, the thickness changes, and the light intensity changes detected by the receiving device will change accordingly. According to the real-time measurement results, the system generates a detection signal to indicate the existence of the joint. The controller is connected to the normally open contact of the second relay in the paper material cabinet of the cigarette machine. The normally open contact of the second relay is closed when the paper change splicing action is triggered, thereby transmitting the paper change signal to the controller. The paper joint is monitored in real time by a photoelectric detection device, and an automatic control system is formed in conjunction with the controller to improve the detection accuracy and automation level of the tipping paper joint of the cigarette machine, improve production efficiency and product quality, avoid production interruptions caused by tipping paper joint problems, reduce material waste, save costs, optimize the maintenance process of the cigarette machine, and improve the quality and stability of cigarette production.

[0076] Optionally, based on the above embodiments, the failure detection system further includes: a second failure alarm device, the second failure alarm device being electrically connected to the controller;

[0077] The controller is also used for: when it is determined that the tipping paper joint detection device fails, sending a trigger signal to the second failure alarm device to control the second failure alarm device to perform a failure alarm.

[0078] In the embodiment of the present invention, the second failure alarm device can be specifically understood as: a device that sends out an alarm signal to notify the operator or the automatic control system when a fault or failure is detected in the kraft paper joint detection device. Specifically, it can be an audible and visual alarm (used to emit sound and prompt light), an indicator light (lights up or changes color, such as from green to red), a display screen alarm (displays alarm information on the human-machine interface, providing more detailed fault information) and a network alarm (sends alarm information via the network to the remote monitoring system or the maintenance personnel's mobile device for remote maintenance).

[0079] Specifically, the second failure alarm device is electrically connected to the controller to receive a trigger signal from the controller. When the controller determines through logical judgment that the detection device has failed (for example, the detection signal is not received within the expected time), the controller sends a trigger signal to the second failure alarm device, activates the second failure alarm device and performs its alarm function, such as making a sound or lighting a warning light, thereby notifying the operator to take necessary maintenance or adjustment measures to ensure the normal operation of the production line or troubleshooting, thereby realizing real-time automatic monitoring of the status of the kraft paper joint detection device. The immediate alarm mechanism greatly improves the reliability and response speed of the system, helps operators quickly identify and deal with problems, thereby reducing production interruptions and material waste, optimizing the maintenance process of cigarette machines, and improving the quality and stability of cigarette production.

[0080] Optionally, based on the above embodiments, the second failure alarm device is a failure alarm light, and the failure alarm light is arranged on the tipping paper button panel.

[0081] Specifically, the second failure alarm device can be a failure alarm light, and it is set on the kraft paper button panel, so that the operator can intuitively identify the status of the kraft paper joint detection device quickly through the light signal, and can see the alarm information at a glance no matter where on the production line, and by setting the alarm light on the button panel, the operator can immediately notice the alarm signal during daily operations, thereby responding quickly, reducing production delays, improving production efficiency, optimizing the maintenance process of the cigarette machine, and improving the quality and stability of cigarette production.

[0082] In a specific example, when the cigarette machine model is ZJ17 cigarette machine and the controller is Siemens S7-200SMARTPLC, an alarm lamp H2 is installed on the tipping paper button panel, the output point Q0.0 of the PLC is connected to the A1 foot of the connector detection failure alarm lamp H2 of the MAX electric cabinet, and the A2 foot of the alarm lamp H2 is connected to the negative 24 volt power line for power supply. Among them, the output terminal of the PLC can be adjusted and designed according to specific application requirements.

[0083] Specific application scenarios

[0084] At present, in the daily production of cigarette making machines, the detection of the joints of the rolling paper and the kraft paper may fail due to aging after long-term use or the detection head being affected by dust. The quality problems caused by the defective cigarettes with undetected paper joints flowing into the downstream may cause a large number of products to become waste, reducing the user's product experience. In daily production, it is mainly up to the operator to manually simulate whether the joint detection status is normal, and a large number of normal cigarettes will be consumed during the simulation test, which is inefficient and increases production costs. In order to solve the above problems, an embodiment of the present invention proposes a failure detection system for the paper joint detection device of the cigarette making machine. Taking the ZJ17 cigarette making machine as an example, the system includes: Siemens 200SMART PLC and alarm indicator light and other parts, which can effectively diagnose whether the detection status of the rolling paper joint and the kraft paper joint of the ZJ17 cigarette making machine is normal, and timely alarm reminders are issued when the sensor is detected to be abnormal.

[0085] Figure 4 This is an electrical schematic diagram of a failure detection system for a paper material joint detection device of a cigarette making machine applicable to an embodiment of the present invention. A Siemens S7-200 SMART PLC,PLC is powered by the positive 24 volt power line (L+ terminal is connected to the +24V power line) and the negative 24 volt power line (M terminal is connected to the -24V power line). I0.0 is connected to the normally open contact of the A40 relay in the SE cabinet of the ZJ17 cigarette making machine to collect the paper splicing and paper changing signal of the SE cabinet. I0.1 is connected to the normally open contact of the A22 relay in the MAX cabinet of the ZJ17 cigarette making machine to collect the tipping paper splicing and paper changing signal of the MAX cabinet. The other end of the relay is connected to the positive 24 volt power line. I0.2 is connected to the No. 6 pin of the X24 terminal in the SE cabinet of the ZJ17 cigarette making machine to collect the paper joint detection B14 output signal of the SE cabinet. I0.3 is connected to the No. 62 pin of the X9 terminal in the MAX cabinet of the ZJ17 cigarette making machine to collect the tipping paper joint detection B15.3 output signal of the MAX. Alarm lights H1 and H2 are installed on the button panel of the MAX electric cabinet. The output point Q0.0 of the PLC is connected to the A1 pin of the connector detection failure alarm light H2 of the MAX electric cabinet, and the A2 pin of the alarm light H2 is connected to the negative 24 volt power line for power supply. The output point Q0.1 of the PLC is connected to the A1 pin of the connector detection failure alarm light H1 of the SE electric cabinet, and the A2 pin of the alarm light H1 is connected to the negative 24 volt power line for power supply. Among them, the wiring terminals and pins in the electric cabinet are determined by the internal wiring of the equipment. The selection of its terminals and pins is related to the model of the cigarette making machine, and the input and output terminals of the PLC can be adjusted and designed according to specific application requirements.

[0086] During the production and operation of the ZJ17 cigarette making machine, when the SE roll paper is ready to be spliced ​​and replaced, after the Siemens S7-200SMART PLC input point I0.0 receives the A40 paper connection signal from the SE cabinet, the PLC connects a timer. When the PLC input point I0.2 does not receive the paper joint detection signal from the SE cabinet within the set time, it is determined that the paper joint detection of the SE cabinet is invalid, and the PLC output point Q0.1 will control the alarm light H1 to alarm. After the PLC input point I0.1 receives the A22 paper tray acceleration signal from the MAX cabinet, the PLC connects another timer. When the PLC input point I0.3 does not receive the paper joint detection signal from the MAX cabinet within the set time, it is determined that the paper joint detection of the MAX cabinet is invalid, and the PLC output point Q0.0 will control the alarm light H2 to alarm. It is used to reduce the quality accidents caused by the failure of the paper joint detection, and the cigarettes with joints are not removed and flow into the downstream. It can also replace the original manual simulation test to see if the joint detection fails, automatically diagnose, and improve the detection efficiency.

[0087] The failure detection system for a paper joint detection device of a cigarette making machine proposed in an embodiment of the present invention can automatically diagnose the joint detection of the rolling paper and the tipping paper, save manpower, improve efficiency, and also reduce the consumption of cigarettes during manual simulation testing.

[0088] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps described in the present invention can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of the present invention can be achieved, and this document does not limit this.

[0089] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
