Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical equipment, and in particular to an automatic arrangement and sorting system for residual cigarette. BACKGROUND

[0002] In the production process of filter cigarettes, due to factors such as raw materials, equipment and the quality of operators, there are problems such as insufficient fullness and tightness of tobacco, blurred work number printing, missing printing, color difference of tipping paper, air leakage at the joint, inconsistent suction resistance and packaging quality defects, thereby forming a certain number of defective cigarette, which is not caused by the quality of tobacco. Therefore, the tobacco can be fully recycled. In the prior art, there are mainly two methods for recycling tobacco in cigarettes. One is to make the surface of the cigarette paper of the cigarette break by water vapor, and then separate the tobacco. Since the tobacco is in contact with water and air, it is easy to cause color change, fragmentation and mold, resulting in degradation of the tobacco, thereby reducing the efficiency of recycling and utilization of the tobacco. The other method is a blowing recovery method, which separates the tobacco from the outer packaging paper tube of the cigarette by blowing air into the outer packaging paper tube of the cigarette. For filter cigarettes, the air flow can only be separated in one direction, which affects the application range of the equipment.

[0003] In the prior art, a patent document with the authorization announcement number: "CN106723322B" discloses an online residual and defective cigarette tobacco recovery device for cigarette machine, which comprises a rack, a sorting device, a rolling tobacco assembly, a separation device, a main motor, a material receiving system, a detection and direction changing system, and a material falling hopper. The material falling hopper is installed at the top of the rack, and the sorting device, the rolling tobacco assembly, the separation device and the main motor are installed at the upper part of the rack. The sorting device, the rolling tobacco assembly and the separation device are installed in sequence from top to bottom. The discharging system is connected with the material receiving system at the lower part of the rack, and the sorting device, the rolling tobacco assembly and the separation device are driven by the main motor. By pre-distinguishing the posture and direction of the cigarette entering the separation wheel, the compressed air flow will not blow out the tobacco in the opposite direction of the filter tip of the cigarette, thereby improving the efficiency of recycling and utilization of the tobacco to a certain extent. However, the residual and defective cigarettes collected by tobacco companies are often of different lengths and in disorder. If manual screening is used, a large amount of manpower and resources will be consumed, which is not conducive to improving production efficiency. SUMMARY

[0004] To solve the above technical problems, the present application provides an automatic arrangement and sorting system for residual cigarettes.

[0005] The present application is achieved by the following technical solutions.

[0006] The application provides an automatic arrangement and sorting system for residual cigarette rods, which comprises a screening device, a longitudinal arrangement device and a transverse arrangement device.

[0007] The relative height between the screening tooth and the surface of the first carrier belt is greater than the diameter of the cigarette rod and less than twice the diameter of the cigarette rod.

[0008] One side of the screening tooth is used as a cigarette-accepting surface, and the other side of the screening tooth is used as a cigarette-overflowing surface. The cigarette-accepting surface is an arc-shaped curved surface, and the cigarette-overflowing surface is a flat surface.

[0009] The screening device further comprises a first support, a storage hopper and a brush roller. The first motor and the storage hopper are fixedly connected to the first support. The brush roller is installed on the first support by using a rolling bearing. The storage hopper and the brush roller are arranged above the first carrier belt. The transmission mechanism is further arranged between the brush roller and the first driven roller.

[0010] The longitudinal arrangement device further comprises a second support. The left and right sides of the second support are fixedly connected to a cigarette-blocking plate. The cigarette-blocking plate is arranged above the second carrier belt. At least one side of the cigarette-blocking plate extends below the first carrier belt. One end of the second carrier belt is engaged with a second driving roller. The other end of the second carrier belt is engaged with a second driven roller. The second support is fixedly connected to a second motor. The transmission mechanism is further arranged between the output shaft of the second motor and the second driving roller. The upper side of the second carrier belt is further provided with a cigarette-stacking blocking plate.

[0011] The longitudinal arrangement device further comprises a speed-increasing motor, an upper pressing roller and a lower supporting roller. The speed-increasing motor is fixedly connected to the second support. The gap between the upper pressing roller and the lower supporting roller is aligned with the end of the second carrier belt. The upper pressing roller is fixedly connected to a first gear. The lower supporting roller is fixedly connected to a second gear. The second gear is engaged with the first gear. The transmission mechanism is further arranged between the output shaft of the speed-increasing motor and the second gear.

[0012] The transverse arrangement device includes a third support and a pair of smoke guide plates, which are parallel to each other. One end of the smoke guide plate is aligned vertically with the surface of the third carrier belt, and the other end of the smoke guide plate is aligned horizontally with the end of the second carrier belt. The smoke guide plate is also fixedly connected to a support plate, which is also fixedly connected to the third support. The smoke guide plate is in the shape of an arc-shaped thin metal plate. The third support is also fixedly connected to a third motor. One end of the third carrier belt is also engaged with a third driving roller, and the other end of the third carrier belt is also engaged with a third driven roller. The transmission mechanism is also disposed between the output shaft of the third motor and the third driving roller.

[0013] The transverse arrangement device also includes a fourth carrier belt, which is parallel to the third carrier belt. One end of the fourth carrier belt engages with the third driving roller 84, and the other end of the fourth carrier belt engages with the third driven roller 85. The distance between the third and fourth carrier belts is 40% to 60% of the length of the cigarette.

[0014] The transmission mechanism includes a drive wheel, a driven wheel, and a transmission belt. The drive wheel is fixedly connected to the output shafts of the first motor, the second motor, the third motor, the speed-increasing motor, and the first driven roller. The driven wheel is fixedly connected to the first drive roller, the second drive roller, the third drive roller, the second gear, and the brush roller. The transmission belt is engaged between the drive wheel and the driven wheel.

[0015] Both the driving pulley and the driven pulley are synchronous belt pulleys, and the transmission belt 24 is a synchronous belt.

[0016] The beneficial effects of this invention are as follows: Using the technical solution of this invention, the collected defective cigarettes are placed into a storage hopper. When the cigarette sieving device is running, it can pick up a constant number of cigarettes, while excess cigarettes fall back into the storage hopper. Cigarettes shorter than the sieve tooth spacing also fall back into the storage hopper. Thus, the cigarette sieving device filters out recyclable cigarettes. Then, the cigarettes are sequentially transported in a single layer along their radial direction using a longitudinal and transverse arrangement device. Compared to existing technologies, this invention first uses automated machinery to screen the length and quantity of defective cigarettes, and then uses automated machinery to arrange and transport the cigarettes neatly. This results in orderly and neat cigarette arrangement, reducing the labor intensity of manual screening and improving screening efficiency and enterprise production efficiency.

Detailed Implementation

[0030] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0031] This invention provides an automatic sorting and arrangement system for residual cigarettes, such as... Figures 1 to 12As shown, the device includes a smoke screening device 49, a longitudinal arrangement device 51, and a transverse arrangement device 52. The smoke screening device 49 includes a first carrier belt 53, the longitudinal arrangement device 51 includes a second carrier belt 54, and the transverse arrangement device 52 includes a third carrier belt 55. The first carrier belt 53, the second carrier belt 54, and the third carrier belt 55 are connected end to end in sequence. The first carrier belt 53 is arranged along an inclined direction. The surface of the first carrier belt 53 is also provided with a plurality of screening teeth 56. The lower end of the first carrier belt 53 meshes with the first driving roller 57, and the upper end of the first carrier belt 53 meshes with the first driven roller 58. The lower end of the first carrier belt 53 is also provided with a first motor 59. A transmission mechanism 60 is provided between the output shaft of the first motor 59 and the first driving roller 57.

[0032] The technical solution of this invention involves placing collected defective cigarettes into a storage hopper. When the cigarette sieving device is running, it can pick up a constant number of cigarettes, while excess cigarettes fall back into the storage hopper. Cigarettes shorter than the spacing between the sieve teeth also fall back into the storage hopper. Thus, the cigarettes that can be recycled are screened out by the cigarette sieving device. Then, the cigarettes are sequentially transported in a single layer along their radial direction by a longitudinal arrangement device and a transverse arrangement device. Compared with the prior art, this invention first uses automated mechanical equipment to screen the length and quantity of defective cigarettes, and then uses automated mechanical equipment to arrange and transport the cigarettes neatly. This results in orderly and neat cigarette arrangement, reducing the labor intensity of manual screening and improving screening efficiency and enterprise production efficiency.

[0033] Specifically, the relative height between the sieve teeth 56 and the surface of the first carrier belt 53 is greater than the diameter of the cigarette but less than twice the diameter of the cigarette. Multiple sieve teeth 56 are arranged at equal intervals along the circumference of the first carrier belt 53, and the projection length of the distance between any two adjacent sieve teeth 56 in the circumferential cross-section of the first carrier belt 53 does not exceed three times the diameter of the cigarette. Each sieve tooth 56 also has a partition groove 87 on its surface, the width of which is less than the length of the cigarette, and the distance between two adjacent partition grooves 87 does not exceed 2.5 times the length of the cigarette. Using the technical solution of this invention, because the surface of the sieve teeth 56 also has partition grooves 87, shorter cigarettes will fall back into the storage hopper through the partition grooves 87, while the sieve teeth 56 can only pick up longer cigarettes, thus achieving automatic screening of cigarette length.

[0034] Furthermore, one side of the sieve teeth 56 serves as the smoke-receiving surface 61, and the other side serves as the smoke-overflowing surface 62. The smoke-receiving surface 61 is an arc-shaped curved surface, while the smoke-overflowing surface 62 is a flat plane. By employing the technical solution of this invention, the sieve teeth can pick up a constant number of cigarettes from the storage hopper each time.

[0035] Specifically, the cigarette sieving device 49 also includes a first support 63, a storage hopper 64, and a brush roller 65. The first motor 59 and the storage hopper 64 are both fixedly connected to the first support 63. The brush roller 65 is mounted on the first support 63 using rolling bearings, and both the storage hopper 64 and the brush roller 65 are positioned above the first carrier belt 53. A transmission mechanism 60 is also located between the brush roller 65 and the first driven roller 58. The first support 63 is also fixedly connected to a cigarette guard plate 68, which covers the upper end of the first carrier belt 53. The cigarette guard plate 68 is an arc-shaped thin metal plate. Using the technical solution of this invention, the brush roller 65 is used to push excess cigarettes back into the storage hopper, thereby ensuring that each sieve tooth can pick up a constant number of cigarettes.

[0036] In addition, the longitudinal arrangement device 51 also includes a second support 69, the left and right sides of which are fixedly connected to a smoke baffle 70. The smoke baffle 70 is disposed above the second carrier belt 54, and at least one side of the smoke baffle 70 extends below the first carrier belt 53. One end of the second carrier belt 54 engages with the second drive roller 71, and the other end of the second carrier belt 54 engages with the second driven roller 72. The second support 69 is also fixedly connected to the second motor 73. The transmission mechanism 60 is also disposed between the output shaft of the second motor 73 and the second drive roller 71. A stacking smoke baffle 74 is also provided above the second carrier belt 54. Using the technical solution of the present invention, when the cigarettes are conveyed forward along their length direction, if the cigarettes are stacked into multiple layers, the stacking smoke baffle 74 will block the upper layer of cigarettes, so that the cigarettes are ultimately conveyed forward in a single layer along their length direction.

[0037] Specifically, there are two smoke baffles 70, positioned on the left and right sides of the second bracket 69. The second bracket 69 is also fixedly connected to one end of a bracket 75, and the other end of the bracket 75 is fixedly connected to one end of a stacking smoke baffle 74, the other end of which extends above the second carrier belt 54. The stacking smoke baffle 74 is made of non-metallic material. By employing the technical solution of this invention, the stacking smoke baffle 74 is made of non-metallic material, thus avoiding wear on the surface of defective cigarettes.

[0038] In addition, the longitudinal arrangement device 51 also includes a speed-increasing motor 76, an upper pressure roller 77, and a lower support roller 78. The speed-increasing motor 76 is fixedly connected to the second support 69. The gap between the upper pressure roller 77 and the lower support roller 78 is aligned with the end of the second carrier belt 54. The upper pressure roller 77 is fixedly connected to the first gear 79, and the lower support roller 78 is fixedly connected to the second gear 80. The second gear 80 and the first gear 79 mesh with each other. The transmission mechanism 60 is also disposed between the output shaft of the speed-increasing motor 76 and the second gear 80. Using the technical solution of the present invention, since the cigarettes in the longitudinal arrangement device 51 and the transverse arrangement device 52 are long and thin, even if their transverse conveying speed is the same as their longitudinal conveying speed, the arrangement spacing during transverse conveying will be large, which is not conducive to improving production efficiency. Therefore, a corresponding speed-increasing mechanism is provided between the longitudinal arrangement device 51 and the transverse arrangement device 52 to quickly adjust the direction of the cigarettes to transverse conveying, ensuring that the transversely conveyed cigarettes are continuously fed into the blowing device for continuous processing, thus improving the overall operating efficiency of the system.

[0039] Specifically, the transverse arrangement device 52 includes a third support 81 and a pair of smoke guide plates 82. These smoke guide plates 82 are parallel to each other. One end of each smoke guide plate 82 is aligned vertically with the surface of the third carrier belt 55, and the other end is aligned horizontally with the end of the second carrier belt 54. The smoke guide plates 82 are also fixedly connected to a support plate 88, which in turn is fixedly connected to the third support 81. The smoke guide plates 82 are arc-shaped thin metal plates. The pair of smoke guide plates 82 and the support plate 88 form a hollow frame. The third support 81 is also fixedly connected to a third motor 83. One end of the third carrier belt 55 engages with a third driving roller 84, and the other end engages with a third driven roller 85. A transmission mechanism 60 is also located between the output shaft of the third motor 83 and the third driving roller 84. Using the technical solution of this invention, the smoke guide plates 82 are used to quickly redirect the longitudinally conveyed cigarettes to transverse conveying.

[0040] Furthermore, the transverse arrangement device 52 also includes a fourth carrier belt 86, which is parallel to the third carrier belt 55. One end of the fourth carrier belt 86 engages with the third drive roller 84, and the other end of the fourth carrier belt 86 engages with the third driven roller 85. The distance between the third carrier belt 55 and the fourth carrier belt 86 is 40% to 60% of the length of the cigarette. Preferably, the width of the third carrier belt 55 is greater than the width of the fourth carrier belt 86. The third bracket 81 is also fixedly connected to one side of the protective belt baffle 89, and the other side of the protective belt baffle 89 covers the top of the third carrier belt 55 or the fourth carrier belt 86. With the technical solution of the present invention, the transverse arrangement device 52 further filters according to the length of the cigarette. When the cigarette falls to the surface of the third carrier belt 55 after passing through the smoke guide plate 82, the short cigarette will fall out of the system through the gap between the third carrier belt 55 and the fourth carrier belt 86, thus completing the further filtering of the cigarette length. The protective belt baffle 89 prevents the short cigarette from falling to the surface of the third carrier belt 55 or the fourth carrier belt 86, ensuring the normal and stable operation of the transverse arrangement device 52.

[0041] Specifically, the transmission mechanism 60 includes a driving pulley 21, a driven pulley 22, and a transmission belt 24. The driving pulley 21 is fixedly connected to the output shafts of the first motor 59, the second motor 73, the third motor 83, the speed-increasing motor 76, and the first driven roller 58. The driven pulley 22 is fixedly connected to the first driving roller 57, the second driving roller 71, the third driving roller 84, the second gear 80, and the brush roller 65. The transmission belt 24 is engaged between the driving pulley 21 and the driven pulley 22. Both the driving pulley 21 and the driven pulley 22 are synchronous pulleys, and the transmission belt 24 is a synchronous belt.

[0042] In addition, the present invention also provides a method for screening, sorting and ranking defective cigarettes, including the following steps:

[0043] Step 1: Using the aforementioned automatic sorting and sorting system for residual cigarettes, the defective cigarettes collected from the output end of the cigarette production line 44 are put into the storage hopper 64.

[0044] Step 2: When the first carrier belt 53 rotates around the first driving roller 57 and the first driven roller 58, each screen tooth 56 picks up the same number of defective cigarettes from the storage hopper 64, transfers them from the lower end of the first carrier belt 53, and falls into the second carrier belt 54 via the upper end of the first carrier belt 53. At the same time, defective cigarettes with a length shorter than the length of the screen tooth 56 and excess defective cigarettes on each screen tooth 56 fall back into the storage hopper 64.

[0045] Step 3: During the process of transferring the defective cigarettes from one end of the second carrier belt 54 and through the other end of the second carrier belt 54 to the third carrier belt 55, the defective cigarettes stacked on top of the bottom layer of defective cigarettes are blocked by the stacking baffle 74, so that the defective cigarettes are arranged in a single layer along the length direction.

[0046] Step 4: The direction of conveying defective cigarettes is changed from longitudinal to transverse by the smoke guide plate 82. The defective cigarettes are arranged in a single layer, single row and single column along the radial direction. When the defective cigarettes are transferred from one end of the third carrier belt 55 and through the other end of the third carrier belt 55 into the smoke trough of the smoke catching wheel 6, defective cigarettes with a length less than the distance between the third carrier belt 55 and the fourth carrier belt 86 are removed from the transverse arrangement device 52.

[0047] First, the length and quantity of defective cigarettes are screened using automated machinery. Then, the cigarettes are arranged and transported in an orderly manner using the same automated machinery. This reduces the labor intensity of manual screening and improves the company's production efficiency.
