Description

Technical Field

[0001] This application relates to the field of cigarette production technology, and in particular to cigarette screening devices and cigarette conveying systems. Background Technology

[0002] The tobacco industry occupies an important position in my country's economy. As the core product of tobacco products, the quality control of cigarettes directly affects the market competitiveness of enterprises and the user experience of consumers. Hollow ends and loose tobacco at the ends of cigarettes are common and significant quality defects in the cigarette production process. These defects refer to problems such as loose tobacco filling at the ends of the cigarettes, resulting in voids, loose areas, and easy shedding of tobacco.

[0003] In related technologies, the detection of empty cigarettes mainly relies on simple photoelectric detection or photographic detection by packaging machines. Photoelectric detection is inefficient, and many empty cigarettes end up in the packaging process. The packaging process identifies empty cigarettes by taking pictures, but this method requires rejecting 20 cigarettes each time, as one empty cigarette results in the rejection of 20, which is a significant waste of material resources. Utility Model Content

[0004] Therefore, it is necessary to provide a cigarette screening device to address the problem of cigarette waste caused by the detection of empty ends and end clippings in existing technologies.

[0005] A cigarette screening device includes an air blowing assembly, a waste cigarette box, a detection assembly, and a controller;

[0006] The waste cigarette bin is located below the detection drum. Both the air blowing assembly and the detection assembly are electrically connected to the controller. The detection assembly is located on one side of the detection drum and is used to acquire an image of a target cigarette located at a preset position on the detection drum. The detection assembly transmits the image information to the controller. Based on the image information of the target cigarette, the controller controls the air blowing assembly to blow air toward the target cigarette, so that the target cigarette detaches from the detection drum and falls into the waste cigarette bin.

[0007] In one embodiment, the air blowing assembly includes a gas generator, a control switch, and a blowing nozzle. The gas generator generates gas, and the blowing nozzle is connected to the gas generator to blow the gas toward the target cigarette. The control switch is disposed between the blowing nozzle and the gas generator and is electrically connected to the controller. The control switch is used to control the on / off connection between the gas generator and the blowing nozzle under the control of the controller.

[0008] In one embodiment, the direction in which the blowing nozzle expels airflow toward the target cigarette is arranged to intersect the radial direction of the detection drum.

[0009] In one embodiment, the detection component includes an image detection element electrically connected to the controller and positioned on one side of the axial direction of the detection drum, and the image detection element corresponds to the preset position to obtain an image of the target cigarette located at the preset position.

[0010] In one embodiment, the detection component further includes an illumination element located on the same side of the detection drum as the image detection element, the illumination element being used to emit light toward the preset position so that the image detection element obtains a clear image.

[0011] In one embodiment, the illumination element is a ring-shaped illumination lamp, and the image detection element corresponds to the central area of ​​the ring-shaped illumination lamp.

[0012] In one embodiment, the image detection device is located on the side opposite to the luminous area of ​​the ring light.

[0013] In one embodiment, the detection component further includes a proximity switch electrically connected to the controller. When the target cigarette passes the preset position, the proximity switch is triggered, causing the controller to control the image detection device to operate in order to obtain image information of the target cigarette.

[0014] In one embodiment, the cigarette screening device further includes an alarm, which is electrically connected to the controller. When the controller detects that the air blowing component has blown air a preset number of times, the controller controls the alarm to sound an alarm.

[0015] This application also provides a cigarette delivery system that can solve at least one of the above-mentioned technical problems.

[0016] A cigarette conveying system includes the cigarette screening device described above, and further includes a detection drum, the surface of which is capable of generating negative pressure to adsorb cigarettes.

[0017] Beneficial effects:

[0018] This application provides a cigarette screening device, including an air blowing assembly, a waste cigarette box, a detection assembly, and a controller. The waste cigarette box is located below a detection drum. Both the air blowing assembly and the detection assembly are electrically connected to the controller. The detection assembly is located on one side of the detection drum and is used to acquire an image of a target cigarette located at a preset position on the detection drum. The detection assembly then transmits the image information to the controller. Based on the image information of the target cigarette, the controller controls the air blowing assembly to blow air towards the target cigarette, causing the target cigarette to detach from the detection drum and fall into the waste cigarette box. This application obtains an image of a target cigarette located at a preset position on the detection drum through the detection assembly and transmits the image information to the controller. Based on the image information of the target cigarette, the controller determines whether the target cigarette has a hollow end or a broken end. When the target cigarette has a hollow end or a broken end, the controller controls the air blowing assembly to blow air towards the target cigarette, causing the target cigarette to detach from the detection drum and fall into the waste cigarette box. This achieves the rejection of cigarettes with hollow ends or broken ends, thus screening the cigarettes and preventing the impact on other cigarettes, avoiding waste.

[0019] This application also provides a cigarette conveying system, including the aforementioned cigarette screening device, and further including a detection drum, on which a negative pressure can be generated to adsorb cigarettes. This cigarette conveying system can achieve at least one of the aforementioned technical effects. Attached Figure Description

[0030] See Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a cigarette screening device provided in an embodiment of this application. Figure 2 This is a schematic diagram of a detection drum in a cigarette conveying system according to an embodiment of this application. The cigarette screening device provided in one embodiment of this application includes an air blowing assembly 100, a waste cigarette box 400, a detection assembly 200, and a controller 300. The waste cigarette box 400 is located below the detection drum 600. Both the air blowing assembly 100 and the detection assembly 200 are electrically connected to the controller 300. The detection assembly 200 is located on one side of the detection drum 600 and is used to acquire an image of a target cigarette located at a preset position on the detection drum 600, and transmit the image information to the controller 300. The controller 300, based on the image information of the target cigarette, controls the air blowing assembly 100 to blow air towards the target cigarette, so that the target cigarette detaches from the detection drum 600 and falls into the waste cigarette box 400.

[0031] Specifically, this application uses the detection component 200 to obtain an image of a target cigarette located at a preset position on the detection drum 600, and transmits the image information to the controller 300. The controller 300 determines whether the target cigarette has a hollow end or a broken end based on the image information. When the target cigarette has a hollow end or a broken end, the controller 300 controls the air blowing component 100 to blow air towards the target cigarette, causing the target cigarette to detach from the detection drum 600 and fall into the waste cigarette box 400. This removes the hollow end or broken end cigarettes 700, screening them to avoid affecting other cigarettes 700 and preventing waste. The waste cigarette box 400 collects the cigarettes 700 blown off the detection drum 600, allowing for reuse and preventing waste.

[0032] It should be noted that the detection drum 600 has suction holes evenly spaced around its circumference on its surface. These suction holes are connected to a negative pressure fan 800, allowing them to generate negative pressure. This causes multiple cigarettes 700 to be adsorbed onto the surface of the detection drum 600, thus transporting the cigarettes 700 as the drum rotates around its axis. Because the cigarettes 700 are fixed to the drum by negative pressure, when the air blowing assembly 100 blows air towards the target cigarette, a force is applied to the target cigarette away from the suction holes, causing the target cigarette to detach from the surface of the detection drum 600.

[0033] During the process of the detection drum 600 driving each cigarette 700 to rotate, each cigarette 700 can be positioned sequentially at a preset position, thereby enabling the detection component 200 to acquire images of each target cigarette at the preset position one by one, thus detecting each cigarette 700 on the detection drum 600 to ensure the reliability of the cigarette 700 screening device.

[0034] See Figure 1 and Figure 2 In one embodiment, the air blowing assembly 100 includes a gas generator 110, a control switch 120, and an air blowing nozzle 130. The gas generator 110 is used to generate gas, and the air blowing nozzle 130 is connected to the gas generator 110 to blow gas toward the target cigarette. The control switch 120 is disposed between the air blowing nozzle 130 and the gas generator 110, and the control switch 120 is electrically connected to the controller 300. The control switch 120 is used to control the on / off connection between the gas generator 110 and the air blowing nozzle 130 under the control of the controller 300.

[0035] Specifically, when the controller 300 determines, based on the image information of the target cigarette, that the target cigarette has a hollow end or a broken end, the controller 300 controls the control switch 120 to open, connecting the gas generator 110 to the air nozzle 130. This allows the gas generated by the gas generator 110 to be ejected through the air nozzle 130, applying force to the target cigarette and causing it to detach from the detection drum 600 and fall into the waste cigarette box 400. Conversely, when the controller 300 determines, based on the image information of the target cigarette, that the target cigarette does not have a hollow end or a broken end, the control switch 120 remains closed. In this case, the gas generator 110 is disconnected from the air nozzle 130, and the air nozzle 130 does not blow air towards the target cigarette, ensuring the target cigarette remains stably positioned on the detection drum 600.

[0036] It should be noted that during the process of the detection component 200 acquiring the target cigarette located at the preset position, the controller 300 determining whether the target cigarette has a hollow end or a broken end based on the image information, and the control switch 120 being activated to allow the blowing nozzle to blow air, a certain reaction time is required. During this reaction time, the detection drum 600 continues to rotate. Therefore, the distance between the blowing nozzle 130 and the preset position is positively correlated with the rotation speed of the detection drum 600, ensuring that the target cigarette can move to the target position corresponding to the blowing nozzle 130 when the blowing nozzle 130 blows air. Preferably, the gas generator 110 is an air compressor.

[0037] See Figure 1 and Figure 2 In one embodiment, the direction in which the airflow from the blowing nozzle 130 toward the target cigarette is intersected with the radial direction of the detection drum 600, so that the airflow from the blowing nozzle 130 toward the target cigarette can apply a component force away from the wheel surface of the detection drum 600 to the cigarette 700 located at the target position, thereby facilitating the separation of the target cigarette from the wheel surface of the detection drum 600.

[0038] See Figure 1 and Figure 2 In one embodiment, the detection component 200 includes an image detection element 210, which is electrically connected to the controller 300 and is located on one side of the axial direction of the detection drum 600. The image detection element 210 corresponds to a preset position to obtain an image of the target cigarette located at the preset position.

[0039] Specifically, along the axial direction of the detection drum 600, the projected outline of the target cigarette at the preset position falls within the projected outline of the image detection element 210, meaning the image detection element 210 corresponds directly to the preset position. This ensures a close distance between the image detection element 210 and the target cigarette at the preset position, with no other components obstructing the view. This allows the image detection element 210 to obtain a clear image, enabling the controller 300 to accurately determine whether the target cigarette has a hollow end or broken ends based on the image information, thus improving the reliability of the cigarette 700 screening device. Preferably, the image detection element 210 is an industrial camera.

[0040] See Figure 1 and Figure 2 In one embodiment, the detection component 200 further includes an illumination element 220, which is located on the same side of the detection drum 600 as the image detection element 210. The illumination element 220 is used to emit light toward a preset position so that the image detection element 210 can obtain a clear image, thereby facilitating the controller 300 to accurately determine whether the target cigarette has a hollow end or a broken end based on the image information, thus improving the reliability of the cigarette 700 screening device.

[0041] See Figure 1 and Figure 2 In one embodiment, the illumination element 220 is a ring-shaped illumination lamp, and the image detection element 210 corresponds to the middle area of ​​the ring-shaped illumination lamp, so that the ring-shaped illumination lamp can provide more uniform light to the image detection element 210, enabling the image detection element 210 to obtain a clearer image.

[0042] See Figure 1 and Figure 2 In one embodiment, the image detection element 210 is located on one side of the area opposite to the light emission of the ring lamp, thereby avoiding the image detection element 210 from blocking the light and ensuring that the image detection element 210 obtains a clear image.

[0043] See Figure 1 and Figure 2 In one embodiment, the detection component 200 further includes a proximity switch 230, which is electrically connected to the controller 300. When the target cigarette passes through a preset position, the proximity switch 230 is triggered, so that the controller 300 controls the image detection component 210 to operate and obtain image information of the target cigarette.

[0044] Specifically, by setting the proximity switch 230, when the target cigarette passes through the preset position, the image acquired by the image detector 210 can accurately capture the target cigarette, thereby enabling the controller 300 to accurately determine whether the target cigarette has a hollow end or a broken end, thus improving the reliability of the cigarette 700 screening device.

[0045] See Figure 1 and Figure 2 In one embodiment, the cigarette 700 sorting device further includes an alarm 500, which is electrically connected to the controller 300. When the controller 300 detects that the air blowing component 100 has blown air a preset number of times, the controller 300 controls the alarm 500 to sound an alarm, thereby reminding the staff to promptly inspect the cigarette 700 conveying system to determine if other components are malfunctioning, avoiding waste of cigarettes 700 and improving the reliability of the cigarette 700 sorting device. Preferably, the alarm 500 is a buzzer.

[0046] In this embodiment, the preset number of times can be three. In other embodiments, the preset number of times can also be four, five, etc., depending on the frequency at which the cigarette 700 produces empty ends or burnt cigarettes under normal circumstances.

[0047] See Figure 1 and Figure 2This application also provides a cigarette 700 conveying system, including the aforementioned cigarette 700 screening device, and a detection drum 600. The detection drum 600 has a negative pressure on its surface to adsorb cigarettes 700. This application obtains an image of a target cigarette located at a preset position on the detection drum 600 through the detection component 200, and transmits the image information to the controller 300. The controller 300 determines whether the target cigarette has a hollow end or a broken end based on the image information. When the target cigarette has a hollow end or a broken end, the controller 300 controls the air blowing component 100 to blow air towards the target cigarette, causing the target cigarette to detach from the detection drum 600 and fall into the waste cigarette box 400. This achieves the rejection of cigarettes 700 with hollow ends or broken ends, thus preventing the impact on other cigarettes 700 and avoiding waste of cigarettes 700.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
