[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of this utility model provides a cigarette conveying device, including: a cigarette conveying channel 1, a detection mechanism 2, and a control system 3.

[0030] Specifically, the testing agency 2 operates along the width of the cigarette conveying channel 1 (e.g., Figure 1 and Figure 2 The X-direction shown is located on the side of the cigarette conveying channel 1, and the detection area of ​​the detection mechanism 2 (as shown) is located on the side of the cigarette conveying channel 1. Figure 2 The area S shown in the figure is higher than the thickness of the cigarette 4 under normal conveying conditions on the cigarette conveying channel 1 (as shown in the figure). Figure 2 (as shown by dimension L in the diagram). The normal conveying state refers to the state where the cigarette packs 4 on the cigarette conveying channel 1 are not blocked. The detection mechanism 2 is used to send a blockage signal when an object is present in the detection area S. The control system 3 is electrically connected to the detection mechanism 2. The control system 3 is used to receive the blockage signal and control the cigarette conveying channel 1 to stop operating when the actual duration of the received blockage signal exceeds a preset duration. For example, the control system 3 is a PLC control system or a microprocessor; both systems have high reliability and stability and can meet the control requirements of the cigarette conveying device.

[0031] The cigarette pack 4 lies within the plane of the cigarette pack conveying channel 1, constrained along the X-direction by both sides of the cigarette pack conveying channel 1, and along the conveying direction of the cigarette pack conveying channel 1 (e.g., ...). Figure 1 The cigarette pack 4 moves forward in the Y direction (as shown in the diagram). Blockage occurs because of resistance encountered during its movement along the Y direction. Therefore, the blockage is reflected in a direction perpendicular to the plane containing the cigarette pack 4. In other words, a blocked cigarette pack will appear as adjacent cigarette packs 4 stacking in a direction perpendicular to the plane containing the cigarette pack 4. After entering the detection area S, the blocked cigarette pack triggers the action of the detection mechanism 2. Specifically, when a blockage occurs in the cigarette pack conveying channel 1, the stacked cigarette packs can enter the detection area S, and their height is sufficient to cut off the detection line emitted by the detection mechanism 2. At this time, the detection mechanism 2 detects the presence of an object and sends out a blockage signal. When a non-blocked cigarette pack passes through the detection mechanism 2, its height is sufficient to cut off the detection line, therefore the detection mechanism 2 will not send any signal.

[0032] This application utilizes a detection mechanism 2 to promptly detect cigarette pack blockages and a control system 3 to stop the cigarette pack conveying channel 1 when the actual duration of the blockage signal exceeds a preset time. This allows workers to remove the blocked cigarette packs in a timely manner, achieving rapid response and handling of blockages. This improves the packaging machine's production efficiency and ensures the stability and reliability of the production process. Furthermore, timely shutdown when cigarette packs are blocked effectively prevents packaging deformation or cigarette damage due to continuous compression, reducing material waste.

[0033] Furthermore, since not all signals detected by the detection agency 2 are valid blockage signals in actual production, some signals may be caused by non-blockage factors such as equipment vibration or worker interference. By setting a preset duration, and only when the actual duration of the blockage signal exceeds the preset duration, the control system 3 controls the cigarette conveying channel 1 to stop operating. This filters out short-duration intermittent signals, accurately identifies the true blockage signal, avoids frequent shutdowns, reduces the labor intensity of workers, and improves the production efficiency of the packaging machine.

[0034] In some implementations, such as Figure 3 As shown, the control system 3 includes a time relay 31 and a processor 32. The time relay 31 is used to count the actual duration of the blockage signal and send the actual duration to the processor 32. The processor 32 is used to compare the actual duration with a preset duration to determine whether the actual duration is greater than the preset duration. Optionally, the preset duration can be set according to actual production needs, with a selectable range of 0.5-1.5 seconds, or the preset duration can be set to 0.6 seconds.

[0035] When the detection mechanism 2 sends a blockage signal, the time relay 31 starts timing and sends the actual duration to the processor 32. Upon receiving the actual duration, the processor 32 compares it with a preset duration. If the actual duration exceeds the preset duration, the processor 32 determines that a blockage has occurred. At this point, the control system 3 issues a control command to stop the operation of the cigarette conveying channel 1 to prevent further deterioration of the blockage and to avoid damage to the equipment due to prolonged blockage.

[0036] In some implementations, such as Figure 1 and Figure 2 As shown, the detection mechanism 2 is a through-beam photoelectric detection switch, which includes a transmitter 21 and a receiver 22 respectively disposed on both sides of the cigarette conveying channel 1 along the X direction. When a blocked cigarette is conveyed to the detection area S, the blocked cigarette can cut off the through-beam path between the transmitter 21 and the receiver 22, and the detection mechanism 2 sends out a blockage signal. Specifically, when no blocked cigarette is present in the detection area S, the light emitted by the transmitter 21 can reach the receiver 22 smoothly, and the detection mechanism 2 does not send any signal. When a blocked cigarette is conveyed to the detection area S, the blocked cigarette will cut off the through-beam path between the transmitter 21 and the receiver 22. At this time, the detection mechanism 2 detects the presence of an object and sends out a blockage signal.

[0037] Optionally, refer to Figure 3 The cigarette conveying device also includes an alarm device 5, which is electrically connected to the control system 3. The alarm device 5 is used to generate an alarm when the control system 3 receives a blockage signal. The alarm device 5 can be installed on the frame of the cigarette conveying channel 1 or on the workshop operating table to ensure that the staff can quickly detect the alarm signal. In this embodiment, the alarm device 5 is preferably an audible and visual alarm, which has both sound and light alarm functions; a buzzer (sound alarm only) or an indicator light (light alarm only) can also be selected according to actual needs. When the control system 3 receives a blockage signal from the detection mechanism 2, it will immediately trigger the alarm device 5 to generate an alarm and continue to alarm until the blockage is resolved.

[0038] Optionally, refer to Figure 3 The cigarette conveying device also includes a reset button 6, which is electrically connected to the control system 3. When the reset button 6 is pressed, the cigarette conveying channel 1 restarts operation. After the worker manually removes the blocked cigarettes, the worker can manually press the reset button 6. At this time, the control system 3 receives a reset signal and controls the cigarette conveying channel 1 to restart operation, allowing the production process to continue.

[0039] Specifically, when the packaging machine starts working, the cigarette packs 4 will be conveyed normally in the cigarette pack conveying channel 1 at the set speed and direction. At this time, the transmitting end 21 of the detection mechanism 2 (taking a common through-beam photoelectric detection switch as an example) continuously emits light, which can smoothly reach the receiving end 22. The detection mechanism 2 is in a normal monitoring state and will not emit any signals. The control system 3 also does not receive any abnormal signals. The cigarette pack conveying channel 1 continues to operate stably, conveying the cigarette packs to the next process. If the cigarette packs 4 accumulate and become blocked during the conveying process due to factors such as fluctuations in the conveyor belt speed, friction between the cigarette packs 4, and wear of equipment parts, the blocked cigarette packs will enter the detection area S of the detection mechanism 2. Since the detection area S is higher than the thickness of the cigarette packs 4 under normal conveying conditions, the blocked cigarette packs will cut off the through-beam path between the transmitting end 21 and the receiving end 22. At this time, the detection mechanism 2 detects the presence of an object in the detection area S and immediately sends out a blockage signal. At the same time, the control system 3 will receive the blockage signal sent by the detection mechanism 2, and then start the time relay 31 to start counting the actual duration of the blockage signal. The time relay 31 sends the statistically obtained actual duration to the processor 32, which compares the actual duration with a preset duration. The preset duration can be flexibly set according to actual production needs, for example, 0.6 seconds. If the actual duration of the blockage signal is less than or equal to 0.6 seconds, it indicates that the signal detected by the detection mechanism 2 may be a false alarm (e.g., external human interference), and the control system 3 will not issue any command to prevent the alarm device 5 from activating and allow the cigarette conveying channel 1 to continue operating. If the actual duration of the blockage signal is greater than 0.6 seconds, it indicates that there is a blockage in the cigarette conveying channel 1. At this time, the control system 3 issues a stop command to the cigarette conveying channel 1, and the cigarette conveying channel 1 immediately stops working to prevent the blockage from worsening and avoid damage to the equipment. In addition, at the same time that the control system 3 receives the blockage signal, the alarm device 5 (such as an audible and visual alarm) electrically connected to the control system 3 will be activated immediately. The audible and visual alarm will promptly remind on-site personnel that there is a blockage in the cigarette conveying channel 1 by emitting a loud sound and flashing lights, so that personnel can quickly go to handle the situation. After arriving at the scene, the staff removed the blocked cigarette packs from the cigarette conveying channel 1, restoring its smooth flow. Then, the staff pressed reset button 6, which sent a reset signal to the control system 3. Upon receiving the reset signal, the control system 3 restarted the cigarette conveying channel 1, allowing the production process to continue.

[0040] Based on the same concept, the present invention also provides a packaging machine, including the cigarette conveying device provided in the above embodiments.
