Description

Technical Field

[0001] This utility model relates to the field of cigarette detection technology, and in particular to a push-type cigarette detection device and detection equipment. Background Technology

[0002] In the cigarette manufacturing industry, the appearance quality of cigarette sticks is one of the indicators for evaluating the pass rate of finished cigarette products. Since cigarette production is a large-scale industrial process, the appearance of cigarette sticks, as end products, must strictly conform to process standards to avoid quality fluctuations caused by production deviations. Therefore, appearance inspection of cigarette sticks is necessary. By inspecting the appearance of cigarette sticks, equipment malfunctions or abnormal process parameters can be detected in a timely manner, reducing scrap rates and lowering production costs. Traditional inspection methods involve random sampling by quality inspectors; however, manual visual inspection is inefficient and highly susceptible to subjective factors.

[0003] A related technology discloses a device for detecting the circumference of a cigarette. By setting an inclined slide between a cigarette separating structure and a visual inspection structure, a single cigarette separated from the cigarette separating structure rolls on the upper slide and then enters the visual inspection structure for detection of the circumference of the cigarette. However, when the cigarette is rolling, the upper slide cannot guarantee stable rolling, and the rolling direction is easily out of control. The cigarette cannot accurately enter the visual inspection structure, resulting in inaccurate detection or the cigarette falling off the upper slide, thus causing poor compatibility and affecting the detection efficiency.

[0044] This embodiment provides a push-type cigarette detection device for detecting the appearance of cigarettes, such as... Figure 1 and Figure 2 As shown, it includes a cigarette sorting unit 1, a pushing unit 2, and a detection and classification unit 3. The cigarette sorting unit 1 includes a cigarette sorting component 12, which can separate cigarettes one by one. The pushing unit 2 is located below the cigarette sorting component 12 and includes a support platform 21 and a pushing component 22. The pushing component 22 is located at one end of the support platform 21, which can receive cigarettes falling from the cigarette sorting component 12. The other end of the support platform 21 is located below the support platform 21. The pushing component 22 can push the cigarettes on the support platform 21 to the detection and classification unit 3.

[0045] During the inspection process, the cigarettes are systematically separated from the group of cigarettes by the cigarette-sorting component 12, falling one by one. Each cigarette lands smoothly on the surface of the support platform 21 after detaching from the cigarette-sorting component 12. When a cigarette falls to one end of the support platform 21, the pushing component 22 is activated, pushing the cigarette on the support platform 21 along its surface to the other end until it is accurately pushed onto the inspection and classification unit 3, thus allowing for the inspection of the appearance of each cigarette. The design of the pushing component 22 ensures that the cigarettes are accurately pushed onto the inspection and classification unit 3 on the support platform 21, preventing tilting when entering the inspection and classification unit 3, achieving stable pushing of the cigarettes, improving the compatibility of the cigarette inspection device, and increasing the efficiency of cigarette appearance inspection.

[0046] Optionally, such as Figure 1 and Figure 2 As shown, the push-type cigarette detection device also includes a fixing unit 4, which is set on the ground. The push component 22 includes a push drive 221 and a pusher 222. The fixed end of the push drive 221 is fixedly connected to the fixing unit 4, and the pusher 222 is drivenly connected to the output end of the push drive 221. The push drive 221 can drive the pusher 222 to slide, so as to push the cigarette to the detection and classification unit 3. When the cigarette is dropped to one end of the support platform 21, the push drive 221 drives the pusher 222 to accurately push the cigarette to the detection and classification unit 3. The entire push process is smooth and efficient, ensuring that a single cigarette can accurately enter the detection stage, providing a reliable guarantee for subsequent quality inspection and classification.

[0047] Specifically, in this embodiment, the push drive 221 is a servo motor. Servo motors offer high precision, fast response, and high efficiency. In other embodiments, the push drive 221 can also be a rotary motor or a rotary cylinder, etc. No limitation is imposed here.

[0048] Optionally, such as Figure 2 As shown, the pushing component 22 also includes a first transmission member 223 and a second transmission member 224. One end of the first transmission member 223 is connected to the output end of the pushing drive member 221, one end of the second transmission member 224 is connected to the other end of the first transmission member 223, and the other end of the second transmission member 224 is fixedly connected to the pushing member 222 to drive the pushing member 222 to slide. When the pushing drive member 221 is activated, the first transmission member 223, which is connected to it, moves synchronously, driving the second transmission member 224 to move synchronously, so that the pushing member 222, which is fixedly connected to it, pushes the cigarette on the carrying platform 21 to the detection and classification unit 3. By setting the first transmission member 223 and the second transmission member 224, the output force of the pushing drive member 221 can be stably transmitted to the pushing member 222, ensuring the stability of force transmission during the movement of the cigarette. It should be noted that in this embodiment, the other end of the second transmission member 224 is welded to the pushing member 222. The welded connection has good stability and high strength. In other embodiments, the other end of the second transmission member 224 is snap-fitted or plugged into the pusher member 222, etc. No limitations are imposed here.

[0049] Specifically, such as Figure 2As shown, in this embodiment, the first transmission component 223 is a gear, and the second transmission component 224 is a rack. The first transmission component 223 is sleeved on the output end of the push drive component 221, and the second transmission component 224 meshes with the first transmission component 223 for transmission. Since the gear and rack motion is existing technology, it will not be described in detail here. In other embodiments, the first transmission component 223 and the second transmission component 224 can also be a combination of a slider and connecting rod, or the first transmission component 223 and the second transmission component 224 can also be a combination of a ball screw, etc. No limitations are imposed here.

[0050] Optionally, such as Figure 2 As shown, the push assembly 22 also includes a protective element 225, which covers the push drive element 221. This protects the push drive element 221 from damage caused by external dust, debris, and accidental impacts, ensuring the reliability and stability of the protection.

[0051] Specifically, in this embodiment, the protective component 225 is a protective cover, which is threadedly connected to the fixing unit 4. In other embodiments, the protective component 225 may also be a protective plate, etc. No limitation is made here.

[0052] Optionally, such as Figure 2 As shown, the supporting platform 21 includes a supporting body connected to the fixing unit 4. The side wall of the supporting body is recessed with a guide groove 211 perpendicular to the movement direction of the cigarette, and the guide groove 211 extends along the movement direction of the cigarette. The pushing assembly 22 also includes a guide member 226, which is movably connected to the pushing member 222. The guide member 226 is located within the guide groove 211 and moves along the extension direction of the guide groove 211. It should be noted that the movement direction of the cigarette is... Figure 2 The front-to-back direction, perpendicular to the direction of movement of the cigarette, is... Figure 2 The left and right directions in the middle.

[0053] The guide member 226 is disposed within the guide groove 211 and can move flexibly along the extension direction of the guide groove 211. In actual operation, when the pusher 222 moves the cigarette, the guide member 226 moves synchronously within the guide groove 211. Through its cooperation with the guide groove 211, not only is the linearity and stability of the pusher 222's movement ensured, but the movement trajectory of the cigarette can also be precisely controlled and adjusted, thereby improving the accuracy and reliability of the cigarette pushing process, and further ensuring that the cigarette on the carrier body is accurately pushed to the detection and classification unit 3. It should be noted that in this embodiment, the guide groove 211 extends along the movement direction of the cigarette and penetrates the carrier body. In other embodiments, the guide groove 211 extends along the movement direction of the cigarette but does not penetrate the carrier body, etc. No limitations are imposed here.

[0054] Specifically, in this embodiment, the guide 226 is a roller. The roller is rotatably connected to the pusher 222, and the roller rolls within the guide groove 211. In other embodiments, the guide 226 may also be a slider, which is rotatably connected to the pusher 222 and slides within the guide groove 211, etc. No limitation is made here.

[0055] Optionally, such as Figure 2 As shown, two guide grooves 211 are provided, symmetrically arranged along the movement direction of the cigarette. Two guide members 226 are also provided, movably connected to both ends of the pusher 222 along a direction perpendicular to the movement direction of the cigarette. The symmetrical distribution of the two guide grooves 211 along the movement direction of the cigarette, along with the two guide members 226, constrains and guides the cigarette from both sides, ensuring that the cigarette maintains a stable posture during the pushing process. This avoids deviation or shaking that could affect subsequent detection, further enhancing the stability of cigarette pushing and effectively improving the efficiency of cigarette detection.

[0056] Optionally, the push-type cigarette detection device further includes an end-face recognition unit 5. One end of the end-face recognition unit 5 is fixedly connected to the ground, and the other end extends towards the cigarette-sorting assembly 12 to identify the end face of the cigarette within the cigarette-sorting assembly 12. The end-face recognition unit 5 allows for the detection of defects on the end face of the cigarette while it passes through the cigarette-sorting assembly 12, achieving real-time monitoring of cigarette quality and preventing defective cigarettes from entering the next production stage or the market. It should be noted that in this embodiment, the end-face recognition unit 5 identifies defects on the end face of the cigarette filter. In other embodiments, the end-face recognition unit 5 identifies defects on the end face of the cigarette tobacco. No limitation is made here.

[0057] Optionally, such as Figure 1 and Figure 3 As shown, in this embodiment, the end-face recognition unit 5 includes an adjustment bracket 51 and a recognition detection element 52. One end of the adjustment bracket 51 is fixedly connected to the ground, one end of the recognition detection element 52 extends towards the cigarette dispensing assembly 12, and the other end of the recognition detection element 52 is detachably connected to the other end of the adjustment bracket 51. This detachable connection facilitates replacement, repair, and maintenance, thereby meeting the installation requirements under different production processes and testing needs, and greatly improving the versatility and adaptability of the recognition detection element 52. It should be noted that the recognition detection element 52 can be any type of detection probe capable of detecting defects on the end face of the cigarette filter.

[0058] Specifically, in this embodiment, the other end of the identification detection element 52 is threadedly connected to the other end of the adjustment bracket 51. In other embodiments, the other end of the identification detection element 52 and the other end of the adjustment bracket 51 can also be connected by a standardized quick-connect buckle, or by a plug-in protrusion and groove, etc., without limitation.

[0059] Optionally, such as Figure 1 and Figure 3 As shown, the cigarette distribution unit 1 also includes a hopper 11, which contains a stack of cigarettes, and the outlet of the hopper 11 is connected to the cigarette distribution assembly 12. The hopper 11 provides a continuous supply of cigarettes to the cigarette distribution assembly 12.

[0060] Optionally, such as Figure 1 and Figure 3 As shown, the smoke distribution assembly 12 includes a smoke distribution wheel 121, a smoke blocking block 122, and a smoke distribution drive 123. The smoke distribution wheel 121 is driven and connected to the output end of the smoke distribution drive 123, and rotates synchronously with the smoke distribution drive 123. Multiple semi-circular arc grooves are evenly distributed on the cylindrical surface of the smoke distribution wheel 121. Each semi-circular arc groove can accommodate one cigarette. The cigarette can rotate through the smoke distribution wheel 121. The smoke blocking block 122 is fixedly connected to the fixed unit 4. The surface of the smoke blocking block 122 opposite to the smoke distribution wheel 121 is arc-shaped. The center of the arc is coaxial with the center of the smoke distribution wheel 121. The side of the smoke blocking block 122 with the arc is arranged opposite to the outlet of the hopper 11 in the front-back direction. The fixed end of the smoke distribution drive 123 is fixedly connected to the fixed unit 4. Cigarettes conveyed from the hopper 11 are separated one by one and enter the semi-circular groove of the cigarette distributor 121 in an orderly manner to avoid jamming. The cigarette distributor 121 is connected to the output end of the cigarette distributor drive 123 and rotates synchronously with the cigarette distributor drive 123. When the cigarette reaches the end of the smoke blocking block 122, the cigarette falls onto the supporting body under the action of gravity. This realizes the individual dropping of cigarettes.

[0061] Specifically, in this embodiment, the smoke-dispersing drive 123 is a stepper motor. Stepper motors are low in cost and simple in structure. In other embodiments, the smoke-dispersing drive 123 can also be a rotary cylinder or a servo motor, etc. No limitation is made here.

[0062] Optionally, such as Figure 1 and Figure 4As shown, the detection and classification unit 3 includes a flipping assembly 32, which includes a flipping drive 321, a flipping bracket 322, a flipping support shaft 323, a fixing frame 324, and a transmission bracket 325.

The flipping bracket 322 is generally L-shaped, with a circular hole on the vertical plate and two waist-shaped grooves on the bottom plate. The flipping bracket 322 is connected to the output shaft of the flipping drive 321 and can follow the flipping drive 321. The output shaft rotates. One end of the flip support shaft 323 is mounted by a bearing in the thick plate hole of the transmission bracket 325, and the other end is mounted by a bearing in the fixed frame 324 as a support for the rotation of the flip assembly 32. The transmission bracket 325 has an overall L-shaped structure, with a short thin plate and a long thick plate in the vertical direction. One end of the bottom plate has two waist-shaped grooves, which correspond one-to-one with the waist-shaped grooves on the flip bracket 322. The transmission bracket 325 is connected to the flip bracket 322 by a combination of bolts, washers and nuts, and can rotate with the output shaft of the flip drive 321 and the flip bracket 322.

[0063] Specifically, in this embodiment, the flipping drive 321 is a stepper motor. Stepper motors are low in cost and simple in structure. In other embodiments, the flipping drive 321 can also be a rotary cylinder or a servo motor, etc. No limitation is made here.

The first rotating shaft 332 and the second rotating shaft 333... The first and second rotating shafts 332 and 333 are arranged in parallel intervals along the front-to-back direction, and the gap between them is smaller than the diameter of the cigarette. The first pulley 334 is coaxially connected to one end of the first rotating shaft 332 and is connected to the drive pulley 336 via a timing belt 337. The second pulley 335 is coaxially connected to one end of the second rotating shaft 333 and is connected to the drive pulley 336 via a timing belt 337. The drive pulley 336 is fixedly connected to the output shaft of the self-rotating drive component 331. The timing belt 337 is sleeved on the outer circumference of the drive pulley 336, the first pulley 334, and the second pulley 335 and is in frictional contact with them. The cigarette on the carrier body can be pushed between the first rotating shaft 332 and the second rotating shaft 333 by the pusher 222. The self-rotation drive 331 drives the first rotating shaft 332 and the second rotating shaft 333 to rotate, thereby causing the cigarette to rotate 360° around its own axis. The detection camera 31 then inspects the appearance of the cigarette, achieving 360° inspection of the cigarette's appearance. It should be noted that the detection camera 31 is positioned directly above the first rotating shaft 332.

[0066] Specifically, in this embodiment, the rotation drive 331 is a stepper motor. Stepper motors are low in cost and simple in structure. In other embodiments, the rotation drive 331 can also be a rotary cylinder or a servo motor, etc. No limitation is made here.

[0071] Optionally, such as Figure 1 As shown, the outer wall of the hopper 11 along the left-right direction abuts against the inner walls of the two side plates 42, and the cigarette distributor 121 is rotatably connected between the two side plates 42. The length of the cigarette is less than or equal to the distance between the inner walls of the hopper 11 along the left-right direction. This allows the cigarettes transported from the hopper 11 to stably enter the semi-circular groove of the cigarette distributor 121. Specifically, in this embodiment, the length of the cigarette is equal to the distance between the inner walls of the hopper 11 along the left-right direction. In other embodiments, the length of the cigarette is less than the distance between the inner walls of the hopper 11 along the left-right direction. No limitation is imposed here.

[0072] Optionally, in this embodiment, the push-type cigarette detection device further includes a control unit (not shown in the figure), which is communicatively connected to the push drive 221, the identification detection unit 52, the cigarette separation drive 123, the flip drive 321, the rotation drive 331, and the detection camera 31.

[0073] This embodiment also provides a detection device, including a cigarette supply device and a push-type cigarette detection device. Along the cigarette's movement direction, the cigarette supply device is located upstream of the push-type cigarette detection device. This ensures that the cigarette is accurately pushed onto the carrying platform 21 to the detection and classification unit 3, preventing the cigarette from tilting when entering the detection and classification unit 3, achieving stable cigarette pushing, improving the compatibility of the cigarette detection device, and increasing the efficiency of cigarette appearance detection.

[0074] The following is combined Figures 1-4 The working principle of the push-type cigarette detection device is explained as follows:

[0075] Cigarettes conveyed from the hopper 11 are separated one by one and orderly enter the semi-circular groove of the cigarette separator 121. The control unit controls the cigarette separator drive 123 to rotate, so that the cigarette separator 121 and the cigarette separator drive 123 rotate synchronously. When the cigarette reaches the end of the smoke blocking block 122, the cigarette falls onto the support body under the action of gravity. At this time, the control unit controls the push drive 221 to start, so that the coaxially fixed first transmission member 223 rotates, and then transmits the driving force to the second transmission member 224 that meshes with it, so that the second transmission member 224 moves along the support body. The forward and backward movement causes the pusher 222 to move along the forward and backward direction on the carrier body, so that the cigarette at one end of the carrier body is pushed to the other end, and the cigarette is pushed and falls between the first rotating shaft 332 and the second rotating shaft 333. When the cigarette falls between the first rotating shaft 332 and the second rotating shaft 333 in the self-rotation assembly 33, the self-rotation drive 331 is activated, and the drive wheel 336 and the synchronous belt 337 transmit power to the first pulley 334 and the second pulley 335, thereby driving the first rotating shaft 332 and the second rotating shaft 333 to rotate synchronously, at the same speed, and in the same direction. Due to friction between the cigarette and the rotating shaft, the cigarette begins to rotate at a constant speed under the rotation of the shaft, achieving a 360° rotation, facilitating comprehensive inspection by the inspection camera 31. The inspection camera 31 transmits the acquired image data to the control unit, which analyzes the images and classifies the cigarettes into two types: defective cigarettes and normal cigarettes. Based on the identification results, it sends a signal to the flipping drive 321, which then starts. The output shaft of the flipping drive 321 is coaxial with the flipping support shaft 323, driving the flipping bracket 322 and the transmission bracket 325 to rotate around the axis of the flipping support shaft 323. When the cigarette... When the type is defective, the flipping drive 321 rotates forward and the flipping component 32 rotates in the forward direction. After rotating to a certain angle, the cigarettes in the gap between the first rotating shaft 332 and the second rotating shaft 333 fall naturally under the action of gravity, so that the defective cigarettes fall into the bad cigarette box 342. When the type of cigarettes is normal, the flipping drive 321 is reversed and the flipping component 32 rotates in the reverse direction. After rotating to a certain angle, the cigarettes in the gap between the first rotating shaft 332 and the second rotating shaft 333 fall naturally under the action of gravity, so that the normal cigarettes fall into the good cigarette box 341, thus realizing the appearance inspection of defective cigarettes and normal cigarettes and their separation after inspection.
