Abstract
Description
Technical Field
[0001] The present application relates to the technical field of cigarette machinery and equipment, and in particular to a cigarette sorting device. Background Art
[0002] At present, all cigarette manufacturers will inevitably produce various unqualified and defective cigarettes during the production process. These cigarettes cannot be sold and circulated, and are called waste cigarettes. However, the tobacco contained in these waste cigarettes is of high value and needs to be recycled, which requires separating the tobacco from the waste cigarettes.
[0003] There are many types of waste cigarette processing equipment, such as beating type, cutting type and other waste cigarette processing machines, as well as air-blowing type waste cigarette processing equipment.
[0004] For air-blowing waste cigarette processing equipment, the main method is to blow high-pressure clean air to the filter side of the waste cigarette to separate the tobacco in the waste cigarette from the paper tube of the waste cigarette, so as to achieve the recycling of tobacco. Although the overall tobacco recycling rate of this air-blowing waste cigarette processing equipment is relatively high, it can only process relatively complete cigarettes with filters, that is, standard waste cigarettes, and it is difficult to apply other defective cigarettes, that is, it is difficult to use air blowing to recycle tobacco from defective cigarettes such as paper scraps, cigarette dust, broken cigarettes, double-mouthed cigarettes, runaway cigarettes, and severely bent cigarettes.
[0005] Based on this, it is necessary to sort the incoming cigarettes before they enter the air-blown waste cigarette processing equipment, and only retain relatively complete cigarettes with filters.
[0006] At present, in the cigarette field, due to the upgrading of cigarette equipment, during the cigarette rolling process, the residual cigarettes and standard waste cigarettes are no longer collected in separate barrels, but are transported to the waste cigarette collection barrel together with a conveyor belt. This causes all the residual cigarettes, standard cigarettes and some non-tobacco foreign objects to be mixed together, increasing the difficulty of sorting.
[0007] In the related art, the cigarettes are sorted manually in the screening system for waste cigarette recycling, which is time-consuming and labor-intensive, and has low sorting efficiency and accuracy. Utility Model Content

[0043] At present, all cigarette manufacturers will inevitably produce various unqualified and defective cigarettes during the production process. These cigarettes cannot be sold and circulated, and are called waste cigarettes. However, the tobacco contained in these waste cigarettes is of high value and needs to be recycled, which requires separating the tobacco from the waste cigarettes.
[0044] In the related art, there are various types of waste cigarette processing equipment, such as beating type, cutting type and other waste cigarette processing machines. The advantages of this type of waste cigarette processing machine are strong processing capacity and high degree of automation. They are more suitable for processing medium and low-grade waste cigarettes in mass production. However, they also have the disadvantages of low tobacco recovery rate and high impurity rate in tobacco, which can easily cause a large amount of tobacco waste.
[0045] In addition, in the related art, there is also an air-blowing waste cigarette processing device, which mainly blows high-pressure clean air to the filter side of the waste cigarette to separate the tobacco in the waste cigarette from the paper tube of the waste cigarette, so as to achieve the recovery of the tobacco. Although the overall tobacco recovery rate of this air-blowing waste cigarette processing equipment is relatively high, it can only process relatively complete cigarettes with filters, that is, standard waste cigarettes, and it is difficult to apply other defective cigarettes, that is, it is difficult to use air blowing to recover tobacco from defective cigarettes such as paper scraps, cigarette dust, broken cigarettes, double-mouthed cigarettes, runaway cigarettes, and severely bent cigarettes.
[0046] Based on this, it is necessary to sort the incoming cigarettes before they enter the air-blown waste cigarette processing equipment, and only retain relatively complete cigarettes with filters.
[0047] At present, in the cigarette field, due to the upgrading of cigarette-making equipment, during the cigarette rod tipping process, the exported defective cigarette rods and standard waste cigarette rods are no longer collected in separate barrels, but are conveyed together to the waste cigarette rod collection barrel by a conveyor belt. This results in all defective cigarette rods, standard cigarette rods, and some non-cigarette foreign objects being mixed together, increasing the difficulty of sorting.
[0048] In the related art, in the screening system for waste cigarette recycling, the sorting of cigarette rods is carried out manually, which is time-consuming and laborious and has low efficiency.
[0049] Based on this, to solve the problem of low sorting efficiency and sorting accuracy caused by manually sorting defective cigarette rods from cigarette rods at present, the embodiments of the present application provide a cigarette rod sorting device, which can effectively improve the sorting efficiency and sorting accuracy of sorting defective cigarette rods from cigarette rods.
[0050] See Figure 1 and Figure 2 , the embodiments of the present application provide a cigarette rod sorting device, which includes a vibration mechanism 100, a first conveying track 200, a detection mechanism 300, and a first sorting mechanism 400.
[0051] The vibration mechanism 100 has a discharge end 110. The vibration mechanism 100 is used to vibrate a plurality of cigarette rods 700 to spread out the plurality of cigarette rods 700 and discharge the plurality of cigarette rods 700 from the discharge end 110.
[0052] The plurality of cigarette rods 700 include standard cigarette rods and first defective cigarette rods. The absolute value of the difference between the length of the standard cigarette rod and the length of the first defective cigarette rod is less than or equal to a first preset value.
[0053] The first conveying track 200 is used to receive and convey the plurality of cigarette rods 700 discharged from the discharge end 110. The detection mechanism 300 is configured to obtain the image information of the plurality of cigarette rods 700 on the first conveying track 200 and mark the first defective cigarette rods among the plurality of cigarette rods 700 according to the image information.
[0054] The first sorting mechanism 400 is communicatively connected to the detection mechanism 300 and is used to take out the marked first defective cigarette rods.
[0055] It should be noted that, in the embodiments of the present application, the vibration mechanism 100 can be configured as a straight-plane vibrator. The vibration mechanism 100 has a plurality of V-shaped grooves distributed at intervals, and all the V-shaped grooves are docked with the discharge end 110 of the vibration mechanism 100. The vibration mechanism 100 vibrates itself to slide the plurality of cigarette rods 700 into each V-shaped groove respectively, so as to spread out and separate the disorderly plurality of cigarette rods 700 into multiple rows and keep them in a straight and flat state, so that the plurality of cigarette rods 700 can be smoothly discharged from the discharge end 110.
[0056] Of course, in other embodiments, the vibration mechanism 100 can also be configured as a conventional vibrating bowl, and no specific limitation is made.
[0057] In this application, the plurality of cigarette rods 700 include standard cigarette rods and first defective cigarette rods. The absolute value of the difference between the length of the standard cigarette rod and the length of the first defective cigarette rod is less than or equal to a first preset value. The standard cigarette rod is understood as a qualified cigarette rod, and the first defective cigarette rod is understood as an unqualified cigarette rod.
[0058] The absolute value of the difference between the length of the standard cigarette rod and the length of the first defective cigarette rod being less than or equal to the first preset value means that: the length of the first defective cigarette rod is approximately equal to the length of the standard cigarette rod, but not exactly equal; or it can be understood that the length of the first defective cigarette rod is slightly greater than or slightly less than the length of the standard cigarette rod. It should be understood that the first preset value is greater than 0, and the first preset value can be set according to the actual length of the standard cigarette rod and the sorting requirements.
[0059] In this application, the first conveying track 200 can be, but is not limited to, conveying structures such as a ring-shaped synchronous belt and a ring-shaped synchronous leather belt. Preferably, the first conveying track 200 is a conveyor belt.
[0060] In this application, the detection mechanism 300 can be arranged above the first conveying track 200. The detection mechanism 300 can be, but is not limited to, a CCD camera. When the first conveying track 200 conveys the plurality of cigarette rods 700 thereon to the lower part of the detection mechanism 300, the detection mechanism 300 takes pictures of the plurality of cigarette rods 700 on the first conveying track 200 to obtain image information of the plurality of cigarette rods 700.
[0061] The detection mechanism 300 can analyze and compare the images of the plurality of cigarette rods 700 obtained with the length of the standard cigarette rod. When the absolute value of the difference between the length of a cigarette rod 700 among the plurality of cigarette rods 700 and the length of the standard cigarette rod is less than or equal to the first preset value, it is determined and marked that this cigarette rod is the first defective cigarette rod. In this way, all the first defective cigarette rods among the plurality of cigarette rods 700 are marked.
[0062] In addition, it should be noted that in order to reduce the reflection interference brought by the conveying plane of the first conveying track 200 to the imaging accuracy of the detection mechanism 300, the first conveying track 200 as a whole can be made of a matte and dark-colored material. For example, the overall structure of the first conveying track 200 is a black belt structure, so that the conveying plane of the first conveying track 200 is a black plane, reducing the imaging interference to the detection mechanism 300 and improving the accuracy of the detection mechanism 300 in marking the first defective cigarette rod.
[0063] In this application, the first sorting mechanism 400 is communicatively connected to the detection mechanism 300 so as to be able to obtain the detection signal of the detection mechanism 300. The first sorting mechanism 400 can also be arranged above the first conveying track 200. Moreover, along the conveying direction of the first conveying track 200, the first sorting mechanism 400 is located downstream of the detection mechanism 300. When the first conveying track 200 conveys a plurality of cigarette rods 700 thereon to below the first sorting mechanism 400, the first sorting mechanism 400 takes out the marked first defective cigarette rod among the plurality of cigarette rods 700 based on the marking of the first defective cigarette rod by the detection mechanism 300. In this way, the first defective cigarette rod among the plurality of cigarette rods 700 is sorted and removed accurately and efficiently.
[0064] It should be noted that the first sorting mechanism 400 can be a cooperative structure of a multi-axis manipulator and a gripper. The first sorting mechanism 400 can also be a cooperative structure of a cylinder and a push rod, and no specific limitation is made.
[0065] It is not difficult to understand that in the cigarette rod sorting device according to the embodiment of this application, through the cooperative setting of the vibration mechanism 100, the first conveying track 200, the detection mechanism 300 and the first sorting mechanism 400, the detection mechanism 300 can obtain the image information of the plurality of cigarette rods 700 on the first conveying track 200 and mark the first defective cigarette rod among the plurality of cigarette rods 700 according to the image information during the process that the first conveying track 200 conveys the plurality of cigarette rods 700 to a predetermined position. The first sorting mechanism 400 accurately sorts and takes out the marked first defective cigarette rod based on the marking of the first defective cigarette rod among the plurality of cigarette rods 700 by the detection mechanism 300, and efficiently removes the first defective cigarette rod with a length approximately similar to that of the standard cigarette rod among the plurality of cigarette rods 700, effectively improving the sorting efficiency and sorting accuracy of sorting out the defective cigarette rods from the cigarette rods 700.
[0066] In some embodiments of this application, referring to Figure 1 and Figure 2 , the first sorting mechanism 400 includes a moving platform 410 and a plurality of gripping members 420 for gripping the first defective cigarette rod, and the moving platform 410 is used to drive the gripping members 420 to move in space.
[0067] Specifically, the moving platform 410 is configured as a multi-axis manipulator, and the gripping member 420 is configured as a gripper cylinder.
[0068] Considering that there are a plurality of first defective cigarette rods among the plurality of cigarette rods 700 on the first conveying track 200, and the distribution positions of the plurality of first defective cigarette rods on the first conveying track 200 are different. Based on this, each gripping member 420 can be independently driven by the moving platform 410 to independently move in space, improving the gripping efficiency of the plurality of first defective cigarette rods.
[0069] Through the cooperation structure of the mobile platform 410 and the gripper 420, multiple first residual cigarette butts on the first conveying track 200 can be accurately and efficiently removed, thereby improving the sorting efficiency of the cigarette butts 700.
[0070] In some embodiments of the present application, refer to Figure 2 and Figure 3 , the multiple cigarette butts 700 further include second residual cigarette butts, the length of the second residual cigarette butts is less than the length of the standard cigarette butts, and the difference between the length of the standard cigarette butts and the length of the second residual cigarette butts is greater than or equal to a second preset value, and the second preset value is greater than the first preset value.
[0071] The cigarette butt sorting device further includes a second sorting mechanism 500, and the second sorting mechanism 500 is arranged between the vibration mechanism 100 and the first conveying track 200, and the second sorting mechanism 500 is used for sorting and collecting the second residual cigarette butts among the multiple cigarette butts 700.
[0072] It should be noted that the second residual cigarette butts can be understood as cigarette butts with shorter lengths such as cigarette filters, non-filter cigarette butts, and broken cigarette butts. Similarly, the second residual cigarette butts are also unqualified cigarette butts. The length of the standard cigarette butts is greater than the length of the second residual cigarette butts, and the difference between the length of the standard cigarette butts and the length of the second residual cigarette butts is greater than or equal to the second preset value, and the second preset value can be set according to the actual length of the standard cigarette butts and the sorting requirements.
[0073] It can be understood that when the vibration mechanism 100 orderly discharges the multiple cigarette butts 700 thereon from the discharge end 110 to the first conveying track 200, the second sorting mechanism 500 pre-sorts and collects the second residual cigarette butts among the multiple cigarette butts 700 discharged by the vibration mechanism 100, so as to pre-remove the second residual cigarette butts among the multiple cigarette butts 700, that is, pre-remove the short cigarette butts in the standard cigarette butts before the standard cigarette butts are discharged into the first conveying track 200.
[0074] Furthermore, refer to Figure 2 and Figure 3 , the second sorting mechanism 500 includes a second conveying track 510, and both ends of the second conveying track 510 are spaced and butted with the discharge end 110 and the first conveying track 200 respectively, and the distance between the second conveying track 510 and the discharge end 110 is greater than the length of the second residual cigarette butts and less than the length of the standard cigarette butts.
[0075] Specifically, the second conveying track 510 can be but is not limited to a conveying structure such as an annular synchronous belt or an annular synchronous leather belt. Preferably, both the second conveying track 510 and the first conveying track 200 are annular conveyor belts.
[0076] It should be understood that the discharge end 110 of the vibration mechanism 100, the second conveying track 510, and the first conveying track 200 are sequentially spaced apart along the conveying direction of the cigarette butts 700.
[0077] Since the distance between the second conveying track 510 and the discharge end 110 is greater than the length of the second residual cigarette and less than the length of a standard cigarette, the distance between the second conveying track 510 and the discharge end 110 forms a first sorting interval 540 capable of sorting out the second residual cigarette from multiple cigarettes 700.
[0078] In this way, when the discharge end 110 of the vibration mechanism 100 discharges multiple cigarettes 700, longer cigarettes such as standard cigarettes and first residual cigarettes can cross the first sorting interval 540 and, under the support and power of the second conveying track 510, cross the first sorting interval 540 and be received by the second conveying track 510 and continue to be conveyed forward.
[0079] However, the second residual cigarette and other shorter cigarettes cannot pass through the first sorting interval 540, but directly fall from the first sorting interval 540. In this way, the second residual cigarettes in the plurality of cigarettes 700 are sorted and removed.
[0080] Furthermore, in order to reduce the risk of standard cigarettes among the multiple cigarettes 700 falling from the first sorting interval 540, the discharge end 110 of the vibration mechanism 100 is slightly higher than the conveying plane of the second conveying track 510, so that the standard cigarettes can be smoothly received by the second conveying track 510 after passing the first sorting interval 540.
[0081] Further, see Figure 2 and Figure 3 The second sorting mechanism 500 also includes a first guide plate 520 and a first collector (not shown in the figure). The first guide plate 520 is arranged at the interval between the discharge end 110 and the second conveying track 510 and is inclined relative to the discharge end 110 and / or the second conveying track 510 to receive the second residual cigarettes dropped from the interval between the discharge end 110 and the second conveying track 510. The first collector is used to collect the second residual cigarettes guided out from the first guide plate 520.
[0082] Specifically, the first guide plate 520 is disposed below the interval between the discharge end 110 and the second conveying track 510, and the first guide plate 520 is disposed obliquely relative to the discharge end 110 and toward the second conveying track 510. The first collector is configured as a collection barrel or a collection box having an opening.
[0083] In this way, the discharge end 110, the first guide plate 520 and the end of the second conveying track 510 are arranged to form a sliding track for the second residual cigarette to slide down, so that the second residual cigarette dropped from the gap between the discharge end 110 and the second conveying track 510 is introduced into the first collector along the first guide plate 520, thereby realizing accurate recovery of the second residual cigarette.
[0084] In addition, the width of the first guide plate 520 can be set to be larger than the width of the discharge end 110 of the vibration mechanism 100, so that the second residual cigarettes guided out from different parts of the discharge end 110 and dropped at the gap between the discharge end 110 and the second conveying track 510 can all be collected by the first collector, thereby improving the efficiency of recovering the second residual cigarettes.
[0085] Considering that there may be a small amount of second residual cigarettes among the multiple cigarettes 700, they may be carried by the standard cigarettes across the distance between the discharge end 110 and the second conveying track 510 and introduced into the second conveying track 510, resulting in a small amount of unsorted and unremoved second residual cigarettes remaining among the multiple cigarettes 700 on the second conveying track 510.
[0086] Based on this, see further Figure 2 and Figure 3 The distance between the second conveying track 510 and the first conveying track 200 is greater than the length of the second remaining cigarette and less than the length of the standard cigarette, and the distance between the second conveying track 510 and the first conveying track 200 is greater than the distance between the second conveying track 510 and the discharge end 110.
[0087] Specifically, the distance between the second conveying track 510 and the first conveying track 200 forms a second sorting interval 550 , and the length of the second sorting interval 550 is greater than the first sorting interval 540 formed between the second conveying track 510 and the discharge end 110 .
[0088] Similarly, in the process of the second conveying track 510 introducing the multiple cigarettes 700 thereon into the first conveying track 200, longer cigarettes such as standard cigarettes can cross the second sorting interval 550 and, under the acceptance and power of the first conveying track 200, are received by the first conveying track 200 and continue to be conveyed forward after crossing the second sorting interval 550.
[0089] However, the second residual cigarette and other shorter cigarettes cannot pass through the second sorting interval 550, but directly fall from the second sorting interval 550. In this way, the second residual cigarettes in the plurality of cigarettes 700 are sorted and removed more comprehensively and thoroughly.
[0090] Similarly, in order to facilitate the recovery of the second residual cigarettes dropped from the second sorting interval 550, a fourth guide plate and a second collector connected to the fourth guide plate can be set at the bottom of the interval between the second conveying track 510 and the first conveying track 200. The structure and effect of the fourth guide plate and the second collector are consistent with the aforementioned first guide plate and the first collector, and will not be repeated here.
[0091] In addition, during the process of the cigarette rod 700 being introduced from the discharge end 110 of the vibration mechanism 100 across the first sorting interval 540 into the second conveying track 510, from the end of the second conveying track 510 across the second sorting interval 550 into the first conveying track 200, during the conveying process of the second conveying track 510, and during the conveying process of the first conveying track 200, problems such as jumping and deviation are likely to occur.
[0092] Through experimental comparison and analysis, it is obtained that when the first conveying track 200 and the second conveying track 510 are configured as conveying belts, controlling the thickness of the conveying belt to be less than or equal to 1.2 mm and the turning radius of the end of the conveying belt to be less than or equal to 15 mm can effectively reduce the jumping and deviation of the cigarette rod 700 during the conveying process, control the jumping and deviation of the cigarette rod 700 during the conveying process within a controllable range, and ensure the stable operation and conveying of the cigarette rod 700 by the first conveying track 200 and the second conveying track 510.
[0093] Furthermore, referring to Figure 3 , the distances between the second conveying track 510 and the discharge end 110 and between the second conveying track 510 and the first conveying track 200 can both be adjusted.
[0094] Specifically, the cigarette rod sorting device according to the embodiment of the present application further includes a frame (not shown in the figure). The second conveying track 510 is movably installed on the frame. By sliding the second conveying track 510 relative to the frame, the installation position of the second conveying track 510 on the frame is adjusted, and further the distances between the second conveying track 510 and the discharge end 110 and between the second conveying track 510 and the first conveying track 200 are adjusted.
[0095] In this way, the first sorting interval 540 formed between the second conveying track 510 and the discharge end 110 and the second sorting interval 550 formed between the second conveying track 510 and the first conveying track 200 can be adapted to sort second residual cigarette rods of various lengths, improving the adaptability and compatibility of the overall cigarette rod sorting device for sorting different types of cigarette rods.
[0096] Furthermore, referring to Figure 2 , Figure 3 and Figure 5 , the second sorting mechanism 500 further includes a partition grid 530. The partition grid 530 and the conveying plane of the second conveying track 510 define a plurality of spaced-apart channels 540. The extending direction of the channels 540 is parallel to the conveying direction of the second conveying track 510.
[0097] Specifically, the partition grid 530 includes a plurality of partition sheets 531 spaced apart along the width direction of the second conveying track 510. The length direction of the partition sheets 531 is consistent with the length direction of the second conveying track 510.
[0098] Thus, multiple partition pieces 531 and the conveying plane of the second conveying track 510 define a plurality of channels 540 spaced apart in the width direction of the second conveying track 510, and both ends of all the channels 540 are respectively butted against the discharging end 110 of the vibrating mechanism 100 and the first conveying track 200 at intervals.
[0099] By defining a plurality of spaced-apart channels 540 through the partition grid 530 and the conveying plane of the second conveying track 510, the plurality of cigarette rods 700 on the second conveying track 510 can be relatively evenly distributed on the conveying plane of the second conveying track 510, avoiding the accumulation and chaos of the plurality of cigarette rods 700, which affects the accuracy of the subsequent detection mechanism 300 for marking the first defective cigarette rod among the plurality of cigarette rods 700, and improving the rejection efficiency of the first defective cigarette rod and the second defective cigarette rod.
[0100] In some embodiments of the present application, referring to Figure 1 、 Figure 2 and Figure 4 , the plurality of cigarette rods 700 further includes a third defective cigarette rod, the length of the third defective cigarette rod is greater than the length of the standard cigarette rod, and the difference between the length of the third defective cigarette rod and the length of the standard cigarette rod is greater than or equal to a third preset value, and the third preset value is greater than the first preset value.
[0101] The cigarette rod sorting device further includes a third sorting mechanism 600, and the third sorting mechanism 600 is arranged at the end of the first conveying track 200, and the third sorting mechanism 600 is used for sorting and collecting the third defective cigarette rods among the plurality of cigarette rods 700.
[0102] It should be noted that the third defective cigarette rod can be understood as a cigarette rod with a longer length, and the difference between its length and the length of the standard cigarette rod is relatively large. Similarly, the third defective cigarette rod is also a defective cigarette rod. The length of the third defective cigarette rod is greater than the length of the standard cigarette rod, and the difference between the length of the third defective cigarette rod and the length of the standard cigarette rod is greater than or equal to the third preset value, and the third preset value can be set according to the actual length of the standard cigarette rod and the sorting requirements.
[0103] It can be understood that after the first sorting mechanism 400 and the second sorting mechanism 500 sequentially sort and remove the second defective cigarette rod and the first defective cigarette rod among the plurality of cigarette rods 700, the plurality of cigarette rods 700 conveyed by the first conveying track 200 to the third sorting mechanism 600 only include two types of cigarette rods, namely the third defective cigarette rod and the standard cigarette rod.
[0104] When the first conveying track 200 orderly conveys the plurality of cigarette rods 700 thereon to the third sorting mechanism 600, the third sorting mechanism 600 sorts and collects the third defective cigarette rods among the plurality of cigarette rods 700, so as to remove the third defective cigarette rods among the plurality of cigarette rods 700, so that only the qualified standard cigarette rods are left among the plurality of cigarette rods 700.
[0105] Further, see Figure 2 and Figure 4 The third sorting mechanism 600 includes a sorting shaft 610 and a second guide plate 620. The sorting shaft 610 is constructed to be able to rotate around itself and is spaced apart from the end of the first conveying track 200. The distance between the sorting shaft 610 and the end of the first conveying track 200 is greater than the length of a standard cigarette and less than the length of the third residual cigarette. The second guide plate 620 is connected to the sorting shaft 610 and is inclined relative to the first conveying track 200.
[0106] Specifically, the axial direction of the sorting shaft 610 is perpendicular to the conveying direction of the first conveying track 200 and parallel to the width direction of the first conveying track 200. The sorting shaft 610 is drivingly connected to a rotary drive member (not shown in the figure) to be driven by the rotary drive member to rotate around itself, and the rotary drive member can be an electric motor, etc.
[0107] Compared with adding another conveying track at the end of the first conveying track 200, the setting of the sorting axis 610 can reduce the space occupied accordingly, improve the overall space utilization of the cigarette sorting device, and reduce the corresponding structural setting cost.
[0108] A third collector for collecting third residual cigarettes is docked at the end of the second material guide plate 620 . The third collector may be a collection barrel or a collection box with an opening.
[0109] In addition, the third sorting mechanism 600 also includes a third guide plate 630, which is arranged between the second guide plate 620 and the first conveying track 200 and is inclined relative to the second guide plate 620 to receive standard cigarettes dropped from the gap between the sorting shaft 610 and the first conveying track 200.
[0110] The third material guide plate 630 is disposed below the end of the first conveying track 200 and is inclined toward the second material guide plate 620. The end of the third material guide plate 630 can be connected to a device for processing standard cigarettes in the next step through a sliding track.
[0111] Since the distance between the sorting shaft 610 and the end of the first conveying track 200 is greater than the length of a standard cigarette and less than the length of a third defective cigarette, a third sorting interval 640 capable of sorting out the third defective cigarettes from multiple cigarettes 700 is formed between the end of the first conveying track 200 and the sorting shaft 610. The third sorting interval 640 is greater than the second sorting interval 550 and also greater than the first sorting interval 540. Thus, when the first conveying track 200 guides multiple cigarettes 700 to the end of the first conveying track 200, the third defective cigarettes can cross the third sorting interval 640 and be conveyed and guided to the second guide plate 620 under the rotation of the sorting shaft 610, and finally slide into the third collector along the inclined second guide plate 620, completing the sorting and collection of the third defective cigarettes.
[0112] Since the standard cigarettes are too short to cross the third sorting interval 640, they directly fall from the third sorting interval 640 to the third guide plate 630, and thus slide along the inclined third guide plate 630 and are guided into the device for processing the standard cigarettes in the next process.
[0113] In this way, the third defective cigarettes in the standard cigarettes are accurately sorted out, removed and recycled, so that the cigarettes guided from the end of the first conveying track 200 to the third guide plate 630 are basically standard cigarettes, thereby improving the sorting efficiency and sorting accuracy of sorting out various types of defective cigarettes from the cigarettes 700.
[0114] Furthermore, in order to reduce the risk of the third defective cigarettes in multiple cigarettes 700 falling from the third sorting interval 640, the conveying plane of the first conveying track 200 is higher than the highest point of the sorting shaft 610, so that the whole sorting shaft 610 is lower than the end of the conveying plane of the first conveying track 200, enabling the third defective cigarettes to be smoothly conveyed to the second guide plate 620 by the sorting shaft 610 after crossing the third sorting interval 640.
[0115] In addition, in order to enhance the smoothness of the sorting shaft 610 in conveying the third defective cigarettes to the second guide plate 620, the radius of the sorting shaft 610 is controlled within a range less than or equal to 15 mm.
[0116] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brief description, 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, it should be considered as the scope recorded in this specification.
[0117] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
