Description

Technical Field

[0001] The present invention discloses a cigarette machine, in particular a cigarette rejection mechanism for the lower cigarette passage, belonging to the technical field of cigarette processing equipment. Background Art

[0002] Cigarettes are consumer goods containing tobacco, and the smoke generated by burning tobacco is inhaled by people. Their production and consumption involve multiple aspects, usually including steps such as tobacco planting, processing, rolling, and packaging.

[0003] A cigarette making machine is a device for manufacturing cigarettes, mainly achieved by rolling tobacco and paper into the form of cigarettes. Industrial-grade cigarette making machines are part of large production lines and are usually used for large-scale production. They have a high level of automation, and their main functions include: cutting, humidifying, and mixing of tobacco; automatically feeding paper rolls and performing necessary processing; the machine rolls tobacco and paper together, and then cuts, seals, and packages them.

[0004] A cigarette packaging machine is used to package the rolled cigarettes for sales and transportation. Its main functions include: automatically loading cigarettes into cartons or other packaging materials; sealing the cartons to ensure the integrity of the products; attaching labels or barcodes to the packages for identification and tracking; loading the packaged cigarettes into larger boxes for batch transportation. Modern cigarette packaging machines usually have a high level of automation, which can improve production efficiency and ensure the consistency and quality of packaging.

[0005] An essential link from the cigarette making machine to the packaging machine is to straighten the cigarettes. The straightening of cigarettes is carried out in a specific lower cigarette passage. As the cigarettes fall, the cigarettes are arranged neatly. The position states through which the cigarettes fall are roughly divided into four types. The first type is that the cigarette axis is perpendicular to the substrate. The second type is that the cigarette axis forms a certain angle with the substrate and the cigarette axis is parallel to the horizontal plane. The third type is that the cigarette axis is perpendicular to the horizontal plane. The fourth type is cigarettes with quality defects, and such cigarettes also belong to the cigarettes that should be rejected, for example: damaged cigarettes, wrinkled cigarettes, cigarette butts, cigarettes with exposed tobacco, etc. Among them, the cigarettes in the first state are the cigarettes that can pass through the passage normally and do not need to be rejected. Since the cigarettes will have different random position states, some cigarettes cannot pass through the passage smoothly and will hinder the cigarettes that can pass through the passage normally. And the cigarettes that cannot pass through smoothly are rejected to ensure that the cigarettes that can pass through normally can pass through the passage smoothly. In the prior art, the cigarettes that cannot pass through the passage smoothly are usually manually rejected, and even need to stop the machine for operation, which seriously affects the production speed. Summary of the Invention

Specific embodiments

[0038] This embodiment is the preferred embodiment of the present invention. All those with the same or similar principles and basic structures as this embodiment are within the protection scope of the present invention.

[0039] Please refer to Figure 1 to Figure 16, the present invention protects a cigarette rejection mechanism for the lower cigarette channel, which mainly includes a substrate 5, a lower cigarette channel 3, and an abnormal cigarette rejection mechanism. The lower cigarette channel 3 is fixedly installed on the substrate 5, and the abnormal cigarette rejection mechanism is fixedly installed on the substrate 5 and is arranged above the lower cigarette channel 3.

[0040] The lower cigarette channel 3 includes more than two channel plates, and a falling channel 8 is formed between adjacent channel plates. In this embodiment, there are twenty falling channels 8, and 20 cigarettes can fall simultaneously. Specifically, in actual implementation, it can also be specifically set according to actual needs. In this embodiment, the falling channel 8 is in an "S" shape, which can prevent the vertically falling cigarettes from falling directly, and can hold them through the "S" - shaped falling channel 8 for manual clearance by the staff.

[0041] In this embodiment, the abnormal cigarette rejection mechanism mainly includes a screw driving motor 7, a screw 13, a driving wheel 11, and a driven wheel 12. The screw 13 is fixedly installed together with the driving wheel 11. The screw driving motor 7 drives the driving wheel 11 to rotate through a belt. The driving wheel 11 drives the screw 13 to rotate, and the belt is hung on the driving wheel 11 and the driven wheel 12. In this embodiment, there are more than two screws 13, and each screw 13 is arranged parallel to each other. The space between adjacent screws 13 corresponds to the falling channel 8. Normal cigarettes can fall into the falling channel 8 through the space between adjacent screws 13. Since there are twenty falling channels 8 in this embodiment, twenty - one screws 13 are provided. Among them, the spiral directions of twenty screws 13 are the same, and the screw 13 near the outermost edge has a thread direction opposite to that of the other screws 13. A driving wheel 11 is fixedly installed on each screw 13, and the number of driven wheels 12 can be specifically set according to actual needs. Preferably, the number of driven wheels 12 is the same as the number of driving wheels 11. In this embodiment, the screw driving motor 7 uses a stepping screw driving motor, which can accurately control the rotation speed. The outer edge of the driving wheel 11 is provided with teeth, and the belt uses a toothed belt, which can effectively prevent slipping between the driving wheel 11 and the belt.

[0042] In this embodiment, the screw 13 includes a support shaft 18 and a thread 17 arranged on the support shaft 18. The driving wheel 11 is fixedly installed together with the support shaft 18. In this embodiment, the thread 17 is square, and the four - corner positions are in an arc chamfer shape. For details, please refer to the appendix Figure 11 . The cross - section of the thread 17 on the screw 13 in this embodiment is designed to be square. Compared with the circular cross - section, its outstanding point is that during the rotation of the screw 13, it can vibrate the cigarettes above and promote the falling of the cigarettes.

[0043] In this embodiment, a mounting frame 16 is fixedly installed on the substrate 5, a mounting plate 15 is fixedly installed on the mounting frame 16, a support plate 9 is fixedly installed on the mounting plate 15. There are two support plates 9 which are arranged in parallel. The driving wheel 11 and the driven wheel 12 are installed between the support plates 9, and a cover plate 10 is fixedly installed above the support plates 9.

[0044] In this embodiment, a bearing seat support rod 19 is fixedly installed on the substrate 5. A bearing seat 14 is fixedly installed at the end of the bearing seat support rod 19. A bearing is installed in the bearing seat 14. The end of the screw rod 13 is inserted into the bearing in the bearing seat 14 and can rotate freely in the bearing. In this embodiment, a bearing is embedded in the bearing seat 14, and the short shaft at the front end of the screw rod 13 is matched with the bearing in the bearing seat.

[0045] In this embodiment, a cigarette dropping upper baffle 2 is fixedly installed above the abnormal cigarette rejecting mechanism, which can restrict the dropped cigarettes and prevent them from dropping randomly.

[0046] In this embodiment, a cigarette dropping lower baffle 4 is fixedly installed at the bottom of the lower cigarette channel 3. A guiding foot 21 is fixedly installed on the cigarette dropping lower baffle 4. The cigarette dropping lower baffle 4 and the guiding foot 21 can be used to limit the cigarettes and prevent them from scattering.

[0047] In this embodiment, the lower cigarette channel cigarette rejecting mechanism further includes a base 1, and the substrate 5 is fixedly installed on the base 1.

[0048] In this embodiment, hinge leaves 20 are respectively fixedly installed on both sides of the substrate 5, and a front baffle can be installed through the hinge leaves 20 to prevent the cigarettes from falling out from the front.

[0049] In this embodiment, the lower cigarette channel 3 is arranged in front of the substrate 5, the bearing seat support rod 19 and the bearing seat are arranged in front of the substrate 5, the screw rod is inserted into the substrate 5, and the driving wheel 11, the driven wheel 12 and the screw rod driving motor 7 are arranged behind the substrate 5, that is, on the back of the substrate 5.

[0050] In this embodiment, an electronic eye support frame 24 is fixedly installed on the back of the substrate 5. An electronic eye is fixedly installed on the electronic eye support frame 24. The electronic eye can adopt a reflective fiber optic sensor. The electronic eye corresponds to the dropping channel 8. When the cigarettes in the dropping channel 8 drop abnormally, the electronic eye will give an alarm.

[0051] In this embodiment, a defective cigarette removing mechanism is fixedly installed on the lower cigarette channel 3. Specifically, a set of defective cigarette removing mechanisms is correspondingly arranged at each falling channel 8. The defective cigarette removing mechanism includes a cylinder rod mounting seat 28, a cylinder rod 29, a connecting plate 30, a removing head 31, a removing motor 33, a removing driving rod 34, a removing driving wheel 35, a removing mechanism fixing frame 36, and a supporting cross plate 32. The cylinder rod mounting seat 28 is fixedly installed at the front end of the lower cigarette channel 3. A cylinder cavity 37 is formed in the lower cigarette channel 3. The cylinder rod 29 is inserted into the cylinder cavity 37 through the cylinder rod mounting seat 28. The removing head 31 is fixedly installed together with the cylinder rod 29 through the connecting plate 30. The removing head 31 can be pushed forward and backward by the cylinder. In this embodiment, the removing head 31 is arranged corresponding to the falling channel 8 and can be used to remove defective cigarettes in the falling channel 8. The removing motor 33 is fixedly installed on the back of the lower cigarette channel 3. The removing driving rod 34 is connected to the removing motor 33, and the removing driving rod 34 can be driven to rotate by the removing motor 33. In this embodiment, two sets of removing driving rods 34 and removing motors 33 are respectively arranged and are arranged in an up-and-down opposite manner. The removing driving wheel 35 is installed between the removing mechanism fixing frames 36. The removing mechanism fixing frames 36 are fixedly installed on the supporting cross plate 32, and the supporting cross plate 32 is installed on the substrate 5. The removing driving wheel 35 is sleeved on the removing driving rod 34, and a set of removing driving wheels 35 is arranged corresponding to each falling channel 8. The defective cigarettes are removed from the falling channel 8 by the clamping of the upper and lower removing driving wheels 35. In this embodiment, two sets of removing driving rods 34 and removing motors 33 are respectively arranged, and all the removing driving wheels 35 are driven by the removing driving rods 34 and the removing motors 33. Specifically, during implementation, multiple sets of removing driving rods 34 and removing motors 33 can also be arranged according to actual needs. When there are defective cigarettes with quality defects in the falling channel 8, the cylinder pushes the removing head 31 to push the defective cigarettes backward until they reach the removing driving wheel 35. The removing motor 33 pulls the defective cigarettes backward through the removing driving wheel 35 for removal.

[0052] The position states through which the cigarette rods fall can be roughly divided into four types. The first is that the axis of the cigarette rod is perpendicular to the substrate. The second is that the axis of the cigarette rod forms a certain angle with the substrate and the axis of the cigarette rod is parallel to the horizontal plane. The third is that the axis of the cigarette rod is perpendicular to the horizontal plane. During the use of the present invention, mainly the cigarette rods in two abnormal position states are removed. Among them, the cigarette rods in the second position state are defined as horizontal cigarette rods. Once a horizontal cigarette rod appears, it will block the entrance of the channel, and the cigarette rods in the normal position state above (the cigarette rods in the first position state mentioned above) cannot continue to pass through the channel. At this time, the above-mentioned screw rod is needed to solve this problem. The specific manifestation in the present invention is that the servo screw driving motor 7 on the belt transmission mechanism provides power to make the belt transmission mechanism move, and then the 21 screw rods 13 start to rotate synchronously. Then, at this time, the horizontal cigarette rod will move towards the back of the substrate 5 under the rotation of the screw rod 13 until it moves out of the channel. At this time, the cigarette rods in the normal position state can continue to fall smoothly through the channel. However, there is also a problem in this removal process, that is, the first 20 screw rods rotate in the same direction synchronously, which will cause the cigarette rods in the normal position state to have a tendency to move and pile up to the right collectively, and it is possible that most of the cigarette rods will fall in the right half of the channel. To solve this problem in the present invention, the spiral direction of the 21st screw rod in the mechanism is designed to be opposite to that of the first 20 screw rods, and under the control of the servo screw driving motor 7, all the screw rods rotate clockwise for several circles and then counterclockwise for several circles, and so on in an alternating manner, so that the cigarette rods are evenly distributed before entering the channel, and the problem of the tendency of the cigarette rods to pile up to the right is well solved.

[0053] The probability of the cigarette rods in the third position state appearing is relatively small. It falls into the channel in the position state where the axis of the cigarette rod is perpendicular to the horizontal plane. Since the falling channel 8 is designed in an "S" shape and the cigarette rod is straight, it will get stuck in the channel. At this time, it only needs to be manually cleared.

[0054] When the present invention is in use, there will also be a fourth state of cigarette rods, that is, cigarette rods with quality defects. Such cigarette rods also belong to the cigarette rods that should be removed. For example: damaged cigarette rods, wrinkled cigarette rods, cigarette rod blanks, cigarette rods with exposed tobacco, etc. in various situations, which are jointly completed by the double-rod cylinder pushing mechanism and the roller group. The specific manifestation is that there is a defective cigarette rod detection and recognition window above the substrate (that is, the lower cigarette channel 3). When it recognizes that the falling cigarette rod has quality defects, the system will transmit the information to the double-rod cylinder pushing mechanism. When the defective cigarette rod falls to the corresponding position of the cylinder pushing mechanism, the cylinder will push the cigarette rod towards the back of the substrate 5 into the gap between the two rollers in the roller group, and the cigarette rod will continue to be removed by the rollers under the action of the relative rotation of the two rollers.

[0055] The present invention eliminates abnormal cigarettes generated during the falling process through an abnormal cigarette rejection mechanism, mainly rejecting the cigarettes in the second, third, and fourth states mentioned in the background art, ensuring that the cigarettes in the first normal position state can smoothly pass through the channel and guaranteeing the smooth progress of subsequent processes.
