Description

Technical Field

[0001] This invention relates to the field of tobacco packaging equipment technology, and more specifically, to a directional arrangement device with filter rod defect detection function. Background Technology

[0002] Cigarette filters are a core component of cigarettes, located in the middle section of the cigarette. They are made primarily of cellulose acetate tow, supplemented with forming paper, plasticizers, and other materials. They are a key component for reducing tar and harmful substances in cigarettes. Their core function is to filter tar and some harmful particulate matter from the smoke, reducing inhalation irritation, improving the smoking experience, and enhancing the structural stability of the cigarette. They are an indispensable auxiliary material for cigarette products.

[0003] Cigarette filter rods require directional conveying during production. Due to their considerable length, a pusher-type feeder is typically used for this purpose. However, this method suffers from the problem of filter rod stacking, and the rods tend to concentrate in one area, resulting in low feeding efficiency. Furthermore, subsequent inspection often employs air-blowing discharge, which only activates when a defective filter rod reaches the designated air-blowing position. This process includes a final inspection step, and while air-blowing discharge requires slots on the side of the track for easier discharge, even qualified filter rods may fall out of these slots, leading to low overall accuracy. Therefore, we propose a directional conveying device with filter rod defect detection functionality. Summary of the Invention

[0004] This invention provides a directional arrangement device with filter rod defect detection function. It reduces the occurrence of material jamming and improves the feeding efficiency by combining vibration dispersion and air blowing discharge. At the same time, after the detection is completed, the mechanical discharge method can achieve higher screening accuracy.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] 1. The present invention discloses a directional arrangement device with filter rod defect detection function. The filter rods are arranged by the cooperation of a push plate and a clamping plate. The conveying plate generates high-frequency micro-vibration through a pneumatic vibrator. The stacked filter rods are separated by vibration, and the protrusions divert the concentrated filter rods, reducing the accumulation of filter rods and making the filter more dispersed. More areas on the upper surface of the push plate can participate in the arrangement process, improving the arrangement efficiency.

[0034] 2. The directional arrangement device with filter rod defect detection function disclosed in this invention blows out the stacked filter rods with compressed air from the jet exhaust during subsequent conveying on the conveyor belt. The combination of vibration dispersion of filter rods and air blowing discharge reduces the probability of material jamming caused by filter rod stacking.

[0035] 3. The directional arrangement device with filter rod defect detection function disclosed in this invention performs real-time scanning and analysis of the internal structure and quality defects of the passing filter rods through a detector to determine whether the length of the filter rod is qualified and whether there are internal defects. When a defective filter rod is detected, the servo motor drives the transition plate to disconnect the conveying track to discharge the defective filter rod. The timing interval is shorter and more accurate, and under normal conveying conditions, the track is a complete track to avoid dropping the filter rod.

[0045] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0046] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0047] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0048] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0049] according to Figures 1 to 5As shown, this application embodiment provides a directional arrangement device with filter rod defect detection function, including:

[0050] Frame 1 has a horizontal L-shaped structure;

[0051] An arranging conveyor mechanism is installed on the vertical end of the frame 1 for axial arrangement of filter rods;

[0052] A horizontal conveying mechanism is set on the horizontal end of the frame 1 and located at the end of the arrangement conveying mechanism, used to convey the axially arranged filter rods in the axial direction.

[0053] The detection mechanism is located at the horizontal end of frame 1 and at the end of the horizontal conveying mechanism; and

[0054] The central control console 12 is located on one side of the frame 1 and is connected to the arrangement conveying mechanism, the horizontal conveying mechanism and the detection mechanism.

[0055] Frame 1 adopts a horizontal L-shaped structure, which naturally connects the vertical arrangement process with the horizontal conveying and testing process. The L-shaped corner realizes a 90-degree turn in the flow direction of the filter rods, which greatly reduces the horizontal footprint of the equipment in the workshop while meeting the axial conveying requirements of long filter rods.

[0056] By physically dividing the filter rods into axial arrangement (vertical end), axial conveying (horizontal end), and online detection (horizontal end section), the three processes of filter rod sorting, directional supply, and quality inspection are forcibly decoupled. The segmented design ensures that each filter rod entering the detection area is in a stable, unidirectional axial posture, avoiding false or missed detections caused by chaotic postures, and providing a reliable prerequisite for accurate rejection in the future.

[0057] An independent central control console 12 is set up and connected to the control of the three major mechanisms, realizing one-click parameter synchronization. Operators do not need to adjust the arrangement speed, conveyor belt speed and detection trigger frequency separately. The central control console 12 can automatically fine-tune the supply rate of the arrangement conveyor mechanism according to the filter rod passing frequency fed back by the detection mechanism, forming a speed self-matching, effectively preventing detection overlap due to excessive feeding or waste of production capacity due to excessive feeding.

[0058] Preferably, in an embodiment, the arrangement conveying mechanism includes a power assembly and multiple sets of clamping plates 27;

[0059] A housing 13 is provided around the vertical end of the frame 1. Multiple sets of clamping plates 27 are arranged between the two side walls of the housing 13 and are arranged in a trapezoidal upward distribution toward the horizontal conveying mechanism. A push plate 26 is connected between each pair of adjacent clamping plates 27. A conveying plate 213 is also provided on the side of the bottom clamping plate 27. The conveying plate 213 is inclined toward the clamping plate 27.

[0060] The power unit is located inside the frame 1 and drives multiple sets of push plates 26 to rise or fall synchronously. The highest height of the push plate 26 is higher than or equal to the adjacent high side clamping plate 27, and the lowest height of the push plate 26 is lower than or equal to the adjacent bottom side clamping plate 27. The top surfaces of the clamping plates 27 and the push plates 26 are both inclined surfaces sloping downwards towards the horizontal conveying mechanism. In addition, the thickness of the push plates 26 decreases from bottom to top, screening layer by layer, so that filter rods that are only in the left and right direction are fed upwards.

[0061] Multiple sets of clamping plates 27 are arranged in a trapezoidal upward distribution, coordinating with the synchronous lifting and lowering of the push plate 26 to construct a physical ladder. Each time the push plate 26 rises, it lifts the filter rod from the lower clamping plate 27 to the upper clamping plate 27, while the downward sloping surface of the top of the clamping plate 27 causes the filter rod to automatically roll to the next level under the action of gravity. This step-by-step mode of lifting, rolling, and lifting avoids the problems of filter rod compression deformation or entanglement that are easily caused by traditional belt friction arrangement.

[0062] Since the top surfaces of both clamping plate 27 and push plate 26 are inclined downwards towards the horizontal conveying mechanism, and the highest point of push plate 26 is higher than the upper clamping plate 27 and the lowest point is lower than the lower clamping plate 27, this forms an effective drop travel. When the filter rod is pushed to the top of the inclined plate, if its posture is slightly skewed, it will automatically correct itself to an orientation parallel to the conveying direction due to the constraints of the side walls on both sides of the inclined plate and the adjustment of its own center of gravity during the rolling process. This is equivalent to completing a posture calibration before entering the horizontal conveying mechanism, which greatly reduces the false defect false alarm rate caused by excessive deflection angle of the filter rod in the subsequent detection mechanism.

[0063] A conveyor plate 213, inclined toward the clamping plate 27, is located beside the bottom clamping plate 27. Utilizing the weight of the filter rods themselves, it automatically slides toward the clamping plate 27 area. When the pusher plate 26 rises to pick up material, the filter rods on the conveyor plate 213 are automatically replenished by gravity, avoiding idle waiting or stacking and achieving a smooth material flow. Multiple sets of clamping plates 27 are enclosed within a housing 13 on the periphery of the vertical end of the frame 1. This housing 13 not only provides mounting references for the side walls of the clamping plates 27 but also forms a relatively enclosed channel for the filter rods to climb.

[0064] Preferably, in the embodiment, the power assembly includes a first motor 22, a top plate 24, and two sets of coaxial rotating wheels 23;

[0065] The first motor 22 is installed inside the frame 1, and two sets of rotating wheels 23 are rotatably connected to the lower side of the conveyor plate 213 through bearing seats. The output end of the first motor 22 is connected to one of the sets of rotating wheels 23 for transmission.

[0066] An eccentric connecting column is fixedly connected between the two sets of rotating wheels 23. A transverse sliding groove 14 is provided on the top plate 24, and the connecting column is located in the sliding groove 14. The bottom surfaces of multiple sets of push plates 26 are all connected to the same fixed frame 25. The fixed frame 25 is connected to the top plate 24 so that the multiple sets of push plates 26 can be driven to rise or fall synchronously by the first motor 22. In addition, in order to ensure the stability of the rise and fall of the top plate 24, both ends of the fixed frame 25 extend to the outside of the top plate 24 and are provided with downward limiting rods. Limiting holes corresponding to the limiting rods are provided on the frame 1. Sliding sleeves for the limiting rods to slide are embedded in the limiting holes, thereby limiting the movement direction of the fixed frame 25 to only rise or fall.

[0067] The connecting column, as an eccentric component, is installed between two sets of coaxial rotating wheels 23, forming a typical crank-slider mechanism in conjunction with the transverse sliding groove 14 on the top plate 24. When the rotating wheels 23 rotate at a constant speed, the lifting and lowering motion of the push plate 26 is not constant, but has a rapid return characteristic of slow rise and fast fall or fast rise and slow fall. This characteristic allows the filter rods sufficient time to roll stably when pushed to the higher clamping plate 27, and to quickly reset during the descent return stroke. Thus, without increasing the motor speed, the single working cycle is shortened, effectively improving the filter rod arrangement efficiency per unit time.

[0068] By setting two sets of coaxial rotating wheels 23, which are stably supported by bearing seats on the underside of the conveyor plate 213, rigid synchronous rotation at two fulcrums is achieved. Compared with single-sided drive, this structure ensures that the rotation angles of the two sets of rotating wheels 23 are completely consistent, making the forces at both ends of the connecting column symmetrical, and ultimately transmitting a purely vertical reciprocating force to the top plate 24. The bottom surfaces of all push plates 26 are connected to the same fixed frame 25, which in turn is connected to the top plate 24. The rigid overall structure ensures that the highest point of the push plate 26 and the lowest point of its descent are completely equal and arrive simultaneously, regardless of the stage of the push plate 26. For the clamping plates 27, which are distributed in a trapezoidal upward pattern, the relatively consistent stroke ensures that the overlap height difference between each stage remains constant, thereby ensuring that the overlap between the top of the push plate 26 and the top surface of the clamping plate 27 is always within the optimal range when the filter rod is transferred from the lower stage to the higher stage.

[0069] Preferably, in this embodiment, a bracket 214 is fixedly connected between the two side walls of the outer shell 13. The bracket 214 has multiple sliding holes. The bottom of the conveying plate 213 is fixedly connected with uniformly distributed support columns. The support columns are slidably connected to the bracket 214 during sliding. Springs 215 are sleeved on the outside of the support columns. The springs 215 are all located between the upper surface of the bracket 214 and the lower surface of the conveying plate 213. The lower surface of the conveying plate 213 is fixedly connected with uniformly distributed pneumatic vibrators 212. The air inlets of the pneumatic vibrators 212 are all connected to an external air pump. The upper surface of the conveying plate 213 is also fixedly connected with uniformly distributed protrusions 211 for dispersing the filter rods under vibration.

[0070] The conveyor plate 213 is slidably connected to the sliding hole of the bracket 214 via a support column, and a spring 215 is sleeved on the outside of the support column, so that the conveyor plate 213 is suspended above the bracket 214. When the pneumatic vibrator 212 is started, the conveyor plate 213 generates high-frequency, low-amplitude forced vibration under the constraint of the spring 215, and the vibration energy is effectively absorbed by the damping effect of the spring 215, and will not be transmitted to the frame 1 and other precision mechanisms. The local suspension vibration design realizes the active dispersion function of the filter rod and isolates the vibration from interference with the detection accuracy and transmission stability.

[0071] The uniformly distributed protrusions 211 fixedly connected to the upper surface of the conveyor plate 213 intermittently collide with and lift the filter rods when the conveyor plate 213 vibrates. The filter rods stacked together are gradually shaken apart and separated from the stacked state by the continuous disturbance of the protrusions 211. At the same time, since the conveyor plate 213 is inclined towards the clamping plate 27, the filter rods will automatically tend to align axially along the inclined direction (i.e., towards the clamping plate 27) under the combined action of vibration and gravity. This is equivalent to completing a coarse orientation at the feed inlet, which significantly reduces the arrangement burden during the subsequent climbing process of the stepped clamping plate 27 and improves the overall arrangement efficiency.

[0072] Multiple sets of springs 215 are evenly distributed between the upper surface of the support 214 and the lower surface of the conveyor plate 213, forming a multi-point elastic support system. When the number of filter rods on the conveyor plate 213 changes (uneven load), each spring 215 will generate different amounts of compression, causing the conveyor plate 213 to automatically fine-tune its level in the vertical direction. For example, the springs 215 on the side with more filter rods are compressed more, and the plate surface sinks slightly, causing the filter rods at that point to accelerate and slide downwards (i.e., to the sides or front) under vibration. This self-leveling characteristic ensures that the filter rods on the conveyor plate 213 are evenly distributed, avoiding material blockage caused by excessive local accumulation.

[0073] The air inlets of the pneumatic vibrator 212 are all connected to an external air pump, and the air supply pressure can be independently adjusted via the central control panel 12 or an independent pressure regulating valve. When producing lightweight cellulose acetate filter rods, a lower air pressure can be used to generate gentle vibration, preventing the filter rods from bouncing too high and causing them to become disorganized. When producing heavier or rough-surfaced filter rods, the air pressure can be increased to enhance the vibration intensity, ensuring that the accumulated filter rods can be effectively dispersed. This characteristic of online adjustable vibration intensity further enhances the equipment's adaptability to different filter rod specifications.

[0074] The conveyor plate 213 is located between the two side walls of the outer casing 13, and the two side walls themselves constitute physical barriers on the left and right sides of the conveyor plate 213. When the filter rods bounce laterally during the vibration dispersion process, they will be blocked by the side walls of the outer casing 13 and bounce back to the middle of the conveyor plate 213, ensuring that all filter rods are within the effective feeding range and will not fall from the side of the conveyor plate 213 into the machine frame 1, thus ensuring the utilization rate of materials and the cleanliness of the equipment.

[0075] Preferably, in the embodiment, the horizontal conveying mechanism includes a second motor 31, a transmission wheel 36, and an inclined plate 32;

[0076] Multiple sets of evenly distributed support frames 35 are provided on the horizontal end of the frame 1, and a support plate 6 is provided in the middle of the support frame 35.

[0077] The second motor 31 is located at one end of the support plate 6, on the side away from the conveying mechanism, and the output end of the second motor 31 is connected to a pulley; the transmission wheel 36 is located at the other end of the support plate 6 and is connected to the pulley via a conveyor belt.

[0078] The support frame 35 is also provided with inclined plates 32 on both sides. The inclined plates 32 have a V-shaped groove structure and are located above the conveyor belt.

[0079] The inclined plates 32 on both sides of the support frame 35 form a V-groove structure and are located above the conveyor belt. When the filter rods roll down from the inclined surface of the arrangement mechanism to the horizontal conveying section, the inclined walls on both sides of the V-groove will generate a centripetal force on the filter rods. Regardless of which side the initial landing point of the filter rod is biased towards, it will automatically roll towards the lowest point of the V-groove under the combined action of gravity and the friction of the conveyor belt. This self-centering effect ensures that the axis of each filter rod is strictly parallel to the direction of movement of the conveyor belt before entering the detection mechanism, and that its lateral position is consistent, eliminating the detection field deviation caused by the left and right offset of the filter rods.

[0080] The inclined plate 32 is located above the conveyor belt, and the filter rods actually contact the upper surface of the conveyor belt. The V-shaped inclined plate 32 only serves as a guide and limiting component on both sides and does not directly support the weight of the filter rods. This design allows the filter rods to be driven by the active friction force of the conveyor belt and laterally constrained by the V-shaped inclined plate 32 during the conveying process, forming a combination of bottom drive and side guidance. Compared with traditional flat belt conveyors, this structure avoids the filter rods rolling laterally on the belt. At the same time, because the filter rods and the conveyor belt have line contact and a small contact area, the risk of friction damage to the printed patterns or air permeability areas on the surface of the filter rods is effectively reduced.

[0081] Multiple sets of evenly distributed support frames 35 are set at the horizontal end of the frame 1. Each set of support frames 35 is supported by a support plate 6 in the middle, which is equivalent to arranging a rigid track with multiple supports along the length of the conveyor belt. Compared with conventional conveyor belts that are only tensioned by rollers at both ends, the multi-point support structure effectively suppresses the sag deformation and lateral deviation of the conveyor belt when it is under heavy load or running at high speed, so that the upper surface of the conveyor belt always remains on the same horizontal reference plane.

[0082] By independently adjusting the speed of the second motor 31 via the central control panel 12, the linear speed of the conveyor belt can be made slightly higher than the theoretical stacking speed corresponding to the discharge frequency of the push plate 26 of the arrangement mechanism. Relying on the tensile effect created by the speed difference, the filter rods, which might otherwise be tightly packed together when rolling down the steps, can be separated by a controllable distance. This ensures that the sensor of the detection mechanism only triggers sampling of a single filter rod each time, completely avoiding signal aliasing and misjudgment caused by multiple filter rods entering the detection field of view simultaneously.

[0083] The inclined plate 32 can be made of self-lubricating materials such as ultra-high molecular weight polyethylene, and its V-shaped inner surface is smooth and has an extremely low coefficient of friction. When the conveyor belt drags the filter rod at high speed, only a weak sliding friction is generated between the filter rod and the side wall of the inclined plate 32. This will not damage the cork paper or filter element end face of the filter rod due to overheating caused by friction, and will also avoid static electricity accumulation and dust adsorption, thus ensuring the cleanliness of the testing environment.

[0084] Preferably, in an embodiment, the horizontal conveying mechanism further includes an air jet 34 and a vision camera 33;

[0085] A gap is also provided on the inclined plate 32 on the side away from the conveying mechanism. The jet exhaust 34 is located in the gap and fixed on the support frame 35. The vision camera 33 is fixedly connected to the upper surface of the frame 1 through the support plate. The vision camera 33 and the jet exhaust 34 are vertically aligned. The air inlets of the air holes of the jet exhaust 34 are all connected to an external air pump for blowing out the upper filter rods stacked in the conveyor belt.

[0086] The vision camera 33 and the jet exhaust 34 are positioned vertically to achieve dual control of the same cross section of the conveyor belt. When the vision camera 33 detects that there are stacked filter rods at this cross section (i.e., one rod is stacked on top of another), the central control panel 12 can instantly trigger the jet exhaust 34 to prevent the stacked rods from entering the subsequent inspection station.

[0087] The jet nozzle 34 is positioned within the gap of the inclined plate 32 and fixed to the support frame 35, with its air holes facing the stacking area on the conveyor belt. When compressed air is ejected, the airflow direction is obliquely upward, applying thrust only to the topmost suspended filter rod, causing it to detach from the top of the lower filter rods and roll back into the V-groove to re-enter the single-row queue, without impacting or displacing the filter rods being normally conveyed below. Utilizing airflow instead of mechanical forks avoids physical damage to the printing or filter paper structure on the filter rod surface caused by hard scraping. The jet nozzle 34 has multiple air holes, each connected to an external air pump. This multi-hole design creates a uniform air curtain across the transverse width of the ejected airflow. Regardless of the transverse offset of the stacked filter rods within the V-groove, they are effectively covered by the air curtain, avoiding the problems of misalignment or missed areas caused by single air holes, and significantly improving the success rate of filter rod separation.

[0088] Preferably, in the embodiment, a downwardly inclined first return trough 4 is also connected to the inclined plate 32 on the other side near the conveying mechanism. The first return trough 4 corresponds to the jet exhaust 34, and a downwardly inclined second return trough 5 is also provided at the bottom of the first return trough 4. The bottom of the second return trough 5 is located above the conveying plate 213. The first return trough 4 and the second return trough 5 are both fixed on the frame 1.

[0089] When the jet nozzle 34 blows the stacked filter rods off the conveyor belt, the filter rods first fall into the downward-sloping first return chute 4, then slide down into the equally downward-sloping second return chute 5, and finally return to the top of the conveyor plate 213. The first return chute 4 is located on the inclined plate 32 near the conveying mechanism and corresponds to the position of the jet nozzle 34. The trajectory of the stacked rods blown out by the jet nozzle 34 is perfectly caught by the inlet of the first return chute 4. This allows the stacked rods to enter the return channel directly without additional guiding devices after separation, eliminating the risk of the filter rods scattering outside the frame 1 or falling into the gaps of the transmission mechanism after being blown out, ensuring the cleanliness of the workshop and the safety of the equipment.

[0090] Preferably, in the embodiment, the detection mechanism includes a detector 81, a third motor 85, and two sets of direct vibration 7;

[0091] Two sets of vertical vibrating 7 are arranged on the horizontal section of the frame 1 and are located on the same horizontal line; one set of vertical vibrating 7 is located at the end of the horizontal conveying mechanism;

[0092] A support frame 88 is also provided between the two sets of direct vibration 7. Four drive wheels 82 are provided on the top lower surface of the support frame 88. The four drive wheels 82 are located in pairs between the two sets of direct vibration 7. A filter rod conveying channel is left between the two drive wheels 82 in the same group. The detector 81 is set on the frame 1 and located between the two sets of drive wheels 82.

[0093] The third motor 85 is fixed to the support frame 88 via the motor base 86, and the output end of the third motor 85 is connected to the drive wheel 84; the axles of the four drive wheels 82 pass through the top of the support frame 88 and are respectively connected to the driven wheels 83; the drive wheel 84 and all the tensioning wheels 87 are connected by a double-sided synchronous belt drive; the double-sided synchronous belt passes in an S-shape between the driven wheels 83 corresponding to the two drive wheels 82 in the same group, so that the two drive wheels 82 in the same group jointly push the filter rod forward.

[0094] Two sets of vertical vibrating filters 7 are set on the same horizontal line. One set is placed at the end of the horizontal conveyor mechanism, and the other set is located at the rear of the testing station. The support frame 88 and its drive wheels 82 are set between the two. This layout allows the filter rod to enter the first set of vertical vibrating filters 7 for posture stabilization after it detaches from the end of the conveyor belt. Then it is taken over by the drive wheels 82 and passes through the testing area. Finally, it is handed over to the second set of vertical vibrating filters 7 for output.

[0095] The double-sided synchronous belt loops in an S-shape between the driven wheels 83 corresponding to the two drive wheels 82 in the same group, giving the two drive wheels 82 opposite directions of rotation. When the filter rod enters the conveying channel between the two drive wheels 82, the left and right drive wheels 82 rotate in opposite directions, applying a pair of equal and opposite tangential frictional forces to the surface of the filter rod, propelling the filter rod forward. This holding-type drive method ensures that the filter rod maintains uniform rolling speed when passing through the detection area, without slippage or vibration, providing the most stable imaging motion state for the detector 81.

[0096] Four drive wheels 82 are positioned in pairs between the two sets of vertical vibrations 7, effectively placing a pair of clamping drive wheels 82 at the front and rear of the detector 81. The front pair of drive wheels 82 is responsible for pulling the filter rod out of the first set of vertical vibrations 7 and feeding it into the testing area, while the rear pair of drive wheels 82 is responsible for pulling the tested filter rod out of the testing area and pushing it into the second set of vertical vibrations 7. This dual-station relay design ensures that the filter rod is actively driven throughout its journey across the field of view of the detector 81, preventing the filter rod from stalling or slowing down midway through the testing process due to inertia depletion, thus ensuring the continuity and reliability of the testing cycle.

[0097] The third motor 85 drives all four drive wheels 82 to rotate simultaneously via a transmission chain consisting of a drive pulley 84, a double-sided synchronous belt, and four driven pulleys 83. Due to the use of a double-sided synchronous belt drive, the rotational speed of all drive wheels 82 is strictly proportional to the speed of the third motor 85, ensuring that the pushing speed of the two sets of drive wheels 82 on the same filter rod is completely consistent. This prevents the filter rod from being stretched (causing deformation) due to a faster initial speed followed by a slower initial speed, and also prevents the filter rod from being squeezed (causing bending or stacking) due to a slower initial speed followed by a faster initial speed. Furthermore, a tensioning pulley 87 is provided on the support frame 88 to adjust the tension of the double-sided synchronous belt. The tensioning pulley 87 plans the path of the double-sided synchronous belt, achieving a reasonable distribution of the belt's wrap angle. The S-shaped wrapping method allows the same set of drive wheels 82 to rotate in opposite directions, while the contact wrap angle of the belt on the driven pulleys 83 is sufficiently large, ensuring sufficient friction to transmit torque. Reasonable tension control and optimized wrap angle design significantly reduce the risk of localized wear and tooth skipping of the synchronous belt, and extend the maintenance cycle and service life of the transmission system.

[0098] The inspection instrument 81 is mounted on the frame 1 and positioned between two sets of drive wheels 82, meaning the inspection station directly faces the middle section of the filter rod, which is suspended and exposed between the two sets of drive wheels 82. At this point, both ends of the filter rod are held by the front and rear drive wheels 82 respectively, while the middle section is completely suspended and unobstructed, providing the inspection instrument 81 with a 360-degree panoramic viewing window. Regardless of whether the inspection instrument 81 uses reflective optical inspection, transmissive X-ray inspection, or laser contour scanning, it can acquire full-dimensional data of the filter rod's surface and interior without blind spots, greatly improving the coverage and accuracy of defect detection.

[0099] Preferably, in the embodiment, a vertical mounting plate 91 is also provided on one side of the straight vibration 7 located behind the detector 81. The bottom of the mounting plate 91 is fixed on the frame 1, and a servo motor 92 is fixedly connected to one side of the mounting plate 91. The output end of the servo motor 92 passes through the mounting plate 91 and is connected to a transition plate 93. The transition plate 93 is located between the two adjacent drive wheels 82 and the straight vibration 7, and a transition channel for connecting the filter rod and the straight vibration 7 is provided on the transition plate 93.

[0100] The servo motor 92 is electrically connected to the central control panel 12 to control the servo motor 92 to drive the transition plate 93 to rotate, which is used to remove defective filter rods detected by the detector 81.

[0101] Servo motor 92 is fixed to one side of the vertical mounting plate 91, and its output end passes through the mounting plate 91 and connects directly to the transition plate 93. As a high-precision angle servo actuator, servo motor 92 has the characteristics of fast response speed (millisecond level) and no overshoot during start and stop. When the detector 81 identifies a defective filter rod, the central control panel 12 sends an electrical signal to servo motor 92, which can drive the transition plate 93 to complete the angle deflection in a very short time. The fast response mechanism ensures that even under the condition of continuous high-speed conveying of filter rods, defective filter rods can still be accurately intercepted after the detection station, avoiding missed rejection due to actuator delay.

[0102] The transition plate 93 is located between the two adjacent drive wheels 82 and the direct vibrator 7, at the output end of the inspection station. This allows the filter rods to immediately enter the sorting stage after completing all the driving and inspection processes. When the filter rod is qualified, the transition channel connects to the direct vibrator 7, and the filter rod enters the next station (such as packaging or collection) along the normal channel; when the filter rod is unqualified, the servo motor 92 drives the transition plate 93 to rotate, causing the transition channel to deviate from the inlet of the direct vibrator 7, and the filter rod is guided to the waste collection area. No additional buffering or handling steps are required, making the inspection and rejection seamless and greatly shortening the process time.

[0103] The transition plate 93 is equipped with a channel for connecting filter rods and a transition channel for the direct vibration 7. The size and shape of this channel are precisely matched to the outer diameter of the filter rods. When the servo motor 92 drives the transition plate 93 to rotate, the inner wall of the channel acts as a wrapping guide for the filter rods, guiding them to smoothly change their direction of movement without impact or sharp bends. The rotation angle range of the servo motor 92 can be set via the central control panel 12, allowing flexible control of the deflection angle of the transition plate 93 in different states. When the equipment needs to change the position of the waste collection box, only the angle parameter of the servo motor 92's rotation endpoint needs to be modified in the software to guide the defective filter rods in different directions without changing any mechanical structure. This software-adjustable feature makes the equipment more adaptable to the workshop layout and allows for more flexible and faster production line adjustments or changes in production lines.

[0104] Preferably, in the embodiment, a discharge port 10 is also provided on the horizontal section of the frame 1. The discharge port 10 is located on the lower side of the transition plate 93. A waste bin 11 is also placed at the lower end of the discharge port 10 to receive the rejected defective filter rods.

[0105] The discharge port 10 is located on the horizontal section of the frame 1 and directly below the transition plate 93. When the servo motor 92 drives the transition plate 93 to deflect, causing the defective filter rod to leave the normal conveying channel, the filter rod falls directly and vertically into the discharge port 10 under the action of gravity. The vertical path design of the upward rejection and downward fall makes the entire process from the defective filter rod being judged as unqualified to entering the waste bin 11 extremely short, without the need for any intermediate transition device or buffer area, effectively avoiding the risk of the rejected filter rod remaining on the frame 1 or rolling to other areas and causing material mixing.

[0106] The waste bin 11 is placed below the discharge port 10, and the size of the discharge port 10 matches the opening range of the waste bin 11, ensuring that every defective filter rod falling from the discharge port 10 can accurately fall into the waste bin 11. This ensures that the entire process of defective filter rods leaving the conveyor channel and entering the waste bin 11 is completed inside the frame 1, completely avoiding the situation where defective filter rods scatter onto the workshop floor or into the gaps of equipment transmission components. This not only ensures the cleanliness of the workshop environment but also eliminates the risk of waste material mixing with qualified products.

[0107] The waste bin 11 adopts a movable, independent box structure, placed below the discharge port 10 of the frame 1, and is not rigidly fixed to the frame 1. When the waste bin 11 is full, the operator can directly pull it out without using any tools or disassembling any parts on the frame 1. This makes waste cleaning extremely simple and quick, significantly reducing the labor intensity and maintenance time of the operators, and is especially suitable for high-speed continuous production scenarios that require frequent emptying of the waste bin 11.

[0108] It should be noted that the electronic equipment structures mentioned in the embodiments of this application, such as the first motor 22, the second motor 31, the third motor 85, the pneumatic vibrator 212, the servo motor 92, the detector 81, the vision camera 33, and the central control console 12, are not existing technologies. This application does not make any improvements to the above structures, nor does it involve any improvements to the software program in the central control console 12.

[0109] This embodiment discloses a directional arrangement device with filter rod defect detection function, the working principle of which is as follows:

[0110] Filter rods are poured into the interior of housing 13 via conveyor belt or manual operation. An external air pump supplies air to the pneumatic vibrator 212, which uses compressed air to drive internal balls, rollers, or turbines to rotate at high speed, generating high-frequency centrifugal force or pulsating force. This causes the conveyor plate 213 to produce continuous high-frequency micro-vibration, which is amplified by the spring 215. The rear end of the upper surface of the conveyor plate 213 tilts downward, and the filter rods slide downward with the vibration of the conveyor plate 213. The accumulated filter rods are dispersed by the vibration, and the protrusions 211 further divert the filter rods, making them more dispersed. When the spring 215 fails or reaches its service life and needs to be replaced, the conveyor plate 213 is removed, and the spring 215 can be directly removed and replaced.

[0111] The first motor 22 drives the entire assembly consisting of two rotating wheels 23 and connecting columns to rotate, which in turn drives the entire assembly consisting of the top plate 24 and the fixed frame 25 to move in a reciprocating linear motion. The limiting rod restricts the degree of freedom of the top plate 24 in the planar direction, so that the entire assembly consisting of the top plate 24 and the fixed frame 25 can only move in a linear motion up and down. The push plate 26 slides up and down between two adjacent clamping plates 27 following the fixed frame 25. The inclined surface of the upper surface of the push plate 26 is parallel to the inclined surface of the upper surface of the clamping plate 27, which conveys the filter rods of the lower layer to the upper layer. The thickness of the push plate 26 increases from front to back, and the filter rods are screened layer by layer, so that only the filter rods in the left and right direction are sent upward.

[0112] The diameter of the connecting column's movement trajectory is the height of the push plate 26's vertical movement. The lowest position of the push plate 26's descent is within 5cm below the lowest point of the slope of the adjacent clamping plate 27 on the front side of the push plate 26. The highest point of the push plate 26's ascent is within 5cm above the highest point of the slope of the adjacent clamping plate 27 on the front side of the push plate 26. This ensures that the filter rods that meet the requirements can be carried by the push plate 26 to the upper clamping plate 27.

[0113] The filter rods arranged in a left-right direction slide down the uppermost clamping plate 27 onto the conveyor belt. The support plate 6 provides support for the middle of the conveyor belt, making the filter rod transport more stable. The inclined plates 32 on both sides form a V-shaped groove, and the filter rods automatically center. At this time, there may still be stacked or partially pressed down at the bottom and forced to tilt. The second motor 31 drives the conveyor belt forward, and the filter rods are transported forward to the position of the air jet 34 (the vision camera 33 feeds back to the center console 12). The stacked filter rods are blown out through the air holes of the air jet 34. In specific implementation, the following method can be used, but it is not the only implementation method: air jet Row 34 has two evenly distributed air holes. The optimal distance between the center of the lower air hole and the conveyor belt is 5mm. The lower air hole supplies air individually, and the air is supplied by a single air hole depending on the state of the filter rod. The distance between the center of the upper air hole and the conveyor belt is 10-15mm. The upper air hole supplies air uniformly and blows air uniformly at 5-second intervals. The upper air hole blows out the part of the filter rod that is higher than the diameter of the filter rod. The stacked filter rods are blown by compressed air onto the first return trough 4. When the raised filter rod is blown away but some of it still stays on the conveyor belt, the lower air hole, which is closer to the air hole, supplies air to blow the filter rod away from the conveyor belt.

[0114] The jet nozzle at position 34 is only used to remove stacked filter rods and is not used for testing. Therefore, it is within the acceptable range for properly arranged filter rods to be misplaced.

[0115] The method for determining the air blowing at the lower air vent is as follows: the vision camera 33 feeds back the image of the position of the jet vent 34 to the central control panel 12, the central control panel 12 performs image recognition, and if the filter rod in a tilted state is detected, the lower air vent closest to the filter rod on the conveyor belt is activated.

[0116] The filter rods blown into the first return trough 4 roll down to the second return trough 5. The left end of the second return trough 5 tilts downward, causing the filter rods inside the second return trough 5 to roll down to the upper end of the conveyor plate 213 for rearrangement.

[0117] The arranged filter rods are conveyed into the track of the vertical vibrator 7 on the left. The vertical vibrator 7 generates oblique micro-amplitude high-frequency vibration through two sets of inclined vibrating motors inside, causing the filter rods to jump and slide slightly on the track and be continuously conveyed forward.

[0118] The output shaft of the third motor 85 drives the drive wheel 84 to rotate, thereby driving the double-sided synchronous belt to rotate. Figure 5 Taking the provided driven wheel position as an example, the winding direction of the double-sided synchronous belt is as follows: right side of the outer arc surface of the driven wheel 83 at the left rear end - left side of the outer arc surface of the driven wheel 83 at the left front end - right side of the outer arc surface of the driven wheel 83 at the right front end - right side of the outer arc surface of the driven wheel 83 at the right rear end - right side of the outer arc surface of the tension wheel 87 - left side of the outer arc surface of the driving wheel 84. Under this winding method, the two driven wheels 83 on the rear side rotate counterclockwise from top to bottom, and the two driven wheels 83 on the front side rotate clockwise from top to bottom. The driving wheel 82 rotates synchronously with the driven wheels 83. The two driving wheels 82 on the left side clamp the filter rod and send the filter rod into the detection port of the detector 81. When the filter rod is sent out from the detection port of the detector 81, the two driving wheels 82 on the right side send the filter rod away from the detector 81. The detector 81 adopts a terahertz cigarette filter rod detector.

[0119] When a defective filter rod is detected, the central control unit 12 activates the servo motor 92, which in turn rotates the transition plate 93. In practice, the following method can be used, but is not the only implementation: If the filter rod is a standard 120mm length, the distance between the filter rod completely detached from the two drive wheels 82 on the right and the left end of the right-side vibrator 7 is 80mm. The width of the transition plate 93 in the left-right direction is 50mm. Under normal circumstances, the filter rod extending 30mm into the track of the vibrator 7 is sufficient for the vibrator 7 to propel the filter rod forward. When the detector 81 determines it to be defective, the servo motor 92 rotates the transition plate 93. Since the transition area is 80mm long, the center of gravity of the filter rod must be located in the transition area, and the filter rod falls due to gravity. The defective filter rod falls directly to the discharge port 10 and then into the waste bin 11, completing the screening process.
