Description

Technical Field

[0001] This invention relates to the field of cigarette pack buffer channel technology, and in particular to an adaptive fully automatic cigarette pack buffer channel. Background Technology

[0002] As living standards improve, consumers have higher and higher requirements for cigarettes, and their personalized needs are also increasing. In order to meet these needs, innovative products, mainly slim cigarettes, have become a new driving force for the development of the tobacco industry. In 2021, the sales volume of innovative cigarette categories increased by 16.39% year-on-year, accounting for 17.32% of the national sales volume, an increase of 2.36 percentage points year-on-year. Among them, the sales volume of slim cigarettes increased by 12.39% year-on-year.

[0003] In light of the current development of the tobacco industry and the rapidly growing market for slim cigarettes, Zhejiang Tobacco Industry Co., Ltd. has formulated a strategic development plan for slim cigarettes and implemented multiple phases of renovations to the slim cigarette production area at the Hangzhou Cigarette Factory. The finished product high-shelf warehouse has achieved fully automated production of slim cigarettes throughout the entire process.

[0004] The entire production process is automated in the finished product high-bay warehouse system, prohibiting manual handling of cigarette packs on the production line. To address the issues with quality inspection and sampling in the automated finished product high-bay warehouse, a dedicated automated sampling inspection channel is provided for the sampling, conveying, and buffering of standard cigarette packs. However, due to the significant difference in dimensions between slim cigarette packs and standard cigarette packs, the cigarette pack sampling and buffering channel cannot fulfill the conveying function for slim cigarette packs, nor can it perform automated sampling inspection of slim cigarette packs.

[0005] To address this issue, the current practice in China's finished cigarette warehouses is to conduct separate sampling inspections of standard and irregularly shaped cigarettes. This involves online automated sampling inspection of standard cigarettes and offline manual sampling inspection of irregularly shaped cigarettes. This approach suffers from numerous problems, including high labor intensity, low efficiency, high production costs, non-standardized operations, easy damage to cigarettes, safety hazards, and low levels of informatization, which does not meet the development requirements of tobacco industry enterprises. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an adaptive fully automatic cigarette pack buffer channel, which can realize the conveying and buffering functions of cigarette packs of different shapes and sizes, solve the scenario where finished cigarette packs of different shapes and sizes need to be buffered centrally, and improve the automation level of cigarette manufacturing enterprises.

[0007] The technical problem to be solved by the present invention is achieved through the following technical solution:

[0008] An adaptive, fully automated cigarette pack buffer channel, comprising:

[0009] A cigarette detection device includes a first pneumatic baffle and a mounting frame, on which three sets of through-beam photoelectric detection devices are mounted;

[0010] The cigarette pack adaptive processing device is the action execution mechanism of the cigarette pack detection device. According to the type of cigarette pack detected by the cigarette pack detection device, it flips and conveys standard cigarette packs or directly conveys irregularly shaped cigarette packs without flipping, so as to increase the cigarette pack buffer capacity of the channel.

[0011] A segmented buffer device for cigarettes is located at the rear end of the adaptive cigarette processing device. It consists of nine segments of the same length arranged in a modular manner as a buffer cigarette conveyor line. It temporarily stores the buffer cigarettes according to the accumulation and conveying working mode. It includes a horizontal conveying mechanism, a second pneumatic baffle, and multiple detection devices.

[0012] The cigarette pack adaptive separation device is located at the outlet of the cigarette pack segmentation buffer device and consists of two sets of clamping mechanisms with detection. The distance from the second pneumatic baffle to the clamping center of the front clamping mechanism is adjusted to be able to hold one and a half standard cigarette packs. The distance from the second pneumatic baffle to the clamping center of the rear clamping mechanism is adjusted to be able to hold one irregularly shaped cigarette pack and half a standard cigarette pack. When the first cigarette pack is a standard cigarette pack, the front clamping mechanism must be able to clamp the second cigarette pack. When the first cigarette pack is an irregularly shaped cigarette pack, the rear clamping mechanism must be able to clamp the second cigarette pack.

[0013] A full cup alarm device for cigarette buffer is installed at the entrance of the segmented cigarette buffer device. When the accumulation station at the entrance buffers cigarettes to be inspected, it triggers the full cup detection device and prompts manual handling.

[0014] The control system is used to supply power and operate the controlled component smoke detection device, the component smoke adaptive processing device, the component smoke segmentation buffer device, the component smoke adaptive separation device, and the component smoke buffer full cup alarm device.

[0015] Preferably, the three sets of through-beam photoelectric detection devices are used to detect cigarettes lying flat as they enter the cigarette detection device. The type of cigarette is determined by the height of the cigarette. The three sets of through-beam photoelectric detection devices are arranged from top to bottom as an irregularly shaped cigarette detection device, a standard cigarette detection device, and a cigarette input / output detection device. When the standard cigarette detection device is triggered but the irregularly shaped cigarette detection device is not triggered, it is determined to be a standard cigarette; when both are triggered, it is determined to be an irregularly shaped cigarette.

[0016] Preferably, the first pneumatic baffle is disposed at the front end of the smoke detection device, and is used to allow the smoke in this section to pass when there is a smoke allowance signal in the current section.

[0017] Preferably, the cigarette pack adaptive processing device includes: a horizontal conveying mechanism, a T-shaped flipping mechanism, and a cigarette pack output detection device. When a standard cigarette pack enters the horizontal conveying mechanism of the cigarette pack adaptive processing device, the T-shaped flipping mechanism, which is in the flipping working state, flips the standard cigarette pack 90°, and the standard cigarette pack continues to be conveyed forward in the flipped posture. When an irregularly shaped cigarette pack to be inspected enters the horizontal conveying mechanism of the cigarette pack adaptive processing device, it directly passes through the T-shaped flipping mechanism, which is in the conveying working state, and the irregularly shaped cigarette pack continues to be conveyed forward in the original posture.

[0018] Preferably, the adaptive cigarette processing device further includes: a flipping position detection device and a cigarette output detection device, wherein the flipping position detection device is used to detect whether the T-shaped flipping mechanism has flipped the standard cigarette in place, and the cigarette output detection device is used to detect whether the cigarette is output from the adaptive processing device.

[0019] Preferably, the horizontal conveying mechanism is a long shaft fitted with a pulley. The pulley is driven to rotate by the friction between the long shaft and the inner hole of the pulley. The pulley and the roller are connected by a round belt, which drives the roller to rotate for conveying. During the conveying process, the cigarette is blocked. The friction between the cigarette and the roller will prevent the roller from rotating, thus avoiding the bottom of the cigarette box from being worn due to friction between the bottom of the cigarette and the rotating roller.

[0020] Preferably, the adaptive cigarette separation device includes: a cigarette output detection device, a standard cigarette detection device, an irregularly shaped cigarette detection device, a front clamping mechanism, and a rear clamping mechanism. Based on the cigarette type detected by the standard and irregularly shaped cigarette detection devices, when the first cigarette is a standard cigarette, the distance from the second pneumatic baffle to the clamping center of the front clamping mechanism is sufficient to hold one and a half standard cigarettes; therefore, the front clamping mechanism can hold the second cigarette and release the first cigarette. When the first cigarette is an irregularly shaped cigarette, the distance from the second pneumatic baffle to the clamping center of the rear clamping mechanism is sufficient to hold one irregularly shaped cigarette and half a standard cigarette; therefore, the rear clamping mechanism can hold the second cigarette and release the first cigarette. When the second pneumatic baffle resets and none of the cigarette detection devices of the front clamping mechanism detect any cigarettes, the front clamping mechanism resets, and subsequent cigarettes are conveyed forward. Similarly, when none of the cigarette detection devices of the rear clamping mechanism detect any cigarettes, the rear clamping mechanism resets, and subsequent cigarettes are conveyed forward.

[0021] Preferably, the cigarette pack full cup alarm device includes: a cigarette pack full cup detection device, a red and yellow dual-color audible and visual alarm device, and an inspection room prompter. When a cigarette pack forms a 9-segment buffer in the cigarette pack segment buffer device, the first segment buffer triggers the cigarette pack full cup detection device for 10 seconds, the control system issues an alarm signal, the on-site red and yellow dual-color audible and visual alarm device sounds and lights up, and the inspection room prompter in the inspection room prompts the inspectors to go to the site for sampling inspection. At the same time, the first pneumatic baffle does not move, continuously blocking the input of subsequent cigarette packs until the triggering state of the cigarette pack full cup detection device is deactivated.

[0022] Preferably, when the inspector performs a random inspection, he sends a cigarette output signal to the control system, and the cigarette adaptive separation device located at the 9th cigarette buffer station of the cigarette segment buffer device is activated to perform the cigarette output operation.

[0023] The above-described technical solution of the present invention has the following beneficial effects:

[0024] This application solves the problem of irregularly shaped cigarette packs not being able to be buffered and transported on the same line as standard cigarette packs, realizing fully automated online sampling inspection of irregularly shaped cigarette packs and standardizing the cigarette production process. At the same time, it reduces the labor intensity of manual operations in automated production lines, improves the efficiency of manual work, and solves a series of problems such as easily damaged cigarette packs in buffer channels, safety hazards, and low levels of informatization, thus ensuring the level of automation and informatization in cigarette manufacturing enterprises.

Detailed Implementation

[0042] Various exemplary embodiments of the present invention will now be described in detail. 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.

[0043] like Figure 1 and Figure 2 As shown, the adaptive fully automatic cigarette pack buffer channel of this application comprises: a cigarette pack detection device 1, a cigarette pack adaptive processing device 2, a cigarette pack segmented buffer device 3, a cigarette pack adaptive separation device 4, a cigarette pack full cup alarm device 5, and a control system 6. Details are as follows:

[0044] like Figure 3As shown, the smoke detection device 1 consists of a first pneumatic baffle 11, a mounting frame 12, an irregularly shaped smoke detection device 13, a standard smoke detection device 14, and a smoke input / output detection device 15. Specifically, three sets of through-beam photoelectric detectors at different heights are mounted on the mounting frame 12 to detect smoke items lying flat as they enter the smoke detection device. The height of the smoke item determines its type, thus differentiating between different smoke item types. The first pneumatic baffle 11 at the front end primarily allows smoke items to enter the current section only when there is a permission signal for smoke entry from the previous section.

[0045] Furthermore, the height of the multiple sets of through-beam photoelectric detection devices in the cigarette detection device 1 is adjustable. The height of the through-beam photoelectric detection devices can be adjusted according to the characteristics of the cigarette type to accurately determine the cigarette type. It can quickly adapt to production adjustments that change the shape and specifications of cigarettes, and is convenient for users.

[0046] Furthermore, the cigarette detection device 1 can use gratings, infrared / laser ranging, and video recognition to replace the through-beam photoelectric detection, thereby improving the intelligence level of the cigarette detection device 1.

[0047] like Figure 4A and Figure 4B As shown, the cigarette pack adaptive processing device 2 consists of a horizontal conveying mechanism 21, a flipping and positioning detection device 22, a T-shaped flipping mechanism 23, and a cigarette pack output detection device 24. Specifically, the cigarette pack adaptive processing device 2 is the actuating mechanism of the cigarette pack detection device 1. Based on the type of cigarette pack detected by the cigarette pack detection device 1, it flips and conveys standard cigarette packs (from lying flat to standing upright), and directly conveys irregularly shaped cigarette packs (which cannot be flipped and stand upright) without flipping, thus processing different types of cigarette packs in a reasonable way to increase the cigarette pack buffer capacity of the channel.

[0048] Furthermore, in addition to the T-shaped flipping mechanism 23, the action execution mechanism of the cigarette adaptive processing device 2 can also be equipped with a rotation mechanism and a clamping centering mechanism to enhance the adaptive capability of the cigarette adaptive processing device 2 and improve its intelligence level.

[0049] like Figure 5As shown, the segmented buffer device 3 for cigarettes consists of a horizontal conveying mechanism 31, a second pneumatic baffle 32, an accumulation blocking photoelectric detection device 33, an accumulation positioning detection device 34, and an accumulation full detection device 35. The horizontal conveying mechanism 31 consists of a long shaft 311, a set of pulleys 312, a circular belt 313, and a roller 314. Specifically, the segmented buffer device 3 is installed after the adaptive cigarette processing device 2 and before the manual inspection port. It consists of nine sections of uniform length arranged in a modular manner as a buffer cigarette conveying line. It temporarily stores buffer cigarettes according to the accumulation conveying working mode, which serves to segment the buffer cigarettes and allow the segmented buffer cigarettes to be output to the manual inspection port in a step-by-step manner. Its purpose is to reduce the driving force when the buffer cigarettes are started to be conveyed and to reduce the rotation time of the rollers during the buffering process, so as to avoid the rollers from rotating for a long time and wearing down the bottom of the cigarette box. Segmented buffering of cigarettes solves the problem of inaccurate control of the step-by-step conveying of cigarettes due to inconsistent cigarette lengths.

[0050] Furthermore, the horizontal conveying mechanism 31 consists of a long shaft 311, a fitted pulley 312, a circular belt 313, and a roller 314. Specifically, the horizontal conveying mechanism 31 uses a long shaft 311 fitted with a pulley 312. The pulley 312 is driven to rotate by the friction between the long shaft 311 and the inner hole of the pulley 312. The circular belt 313 connects the pulley and the roller 314, driving the roller 314 to rotate for conveying. During the conveying process, the cigarette pack is blocked, and the friction between the cigarette pack and the roller will prevent the roller from rotating, thus avoiding wear on the bottom of the cigarette pack box due to friction between the bottom of the cigarette pack and the rotating roller.

[0051] Furthermore, the horizontal conveying mechanism 31 of the cigarette segmentation buffer device 3 can be replaced by multiple short belt conveyors, which has the characteristic of being compatible with multiple conveying methods.

[0052] like Figure 6As shown, the adaptive cigarette separation device 4 consists of a cigarette output detection device 41, an irregularly shaped cigarette detection device 43, a standard cigarette detection device 42, a front clamping mechanism 44, and a rear clamping mechanism 45. Specifically, the adaptive cigarette separation device 4 is located at the outlet of the cigarette segmentation buffer device 3 and mainly consists of two sets of clamping mechanisms with detection capabilities. The distance from the second pneumatic baffle 32 to the clamping center of the front clamping mechanism is adjusted to be able to hold one and a half standard cigarettes, and the distance from the second pneumatic baffle 32 to the clamping center of the rear clamping mechanism is adjusted to be able to hold one irregularly shaped cigarette and half a standard cigarette. When the first cigarette is a standard cigarette, the front clamping mechanism will definitely be able to clamp the second cigarette; when it is an irregularly shaped cigarette, the rear clamping mechanism will definitely be able to clamp the second cigarette. Based on the type of cigarette detected by the photoelectric detection device of the front clamping mechanism, if the first cigarette is a standard cigarette, the front clamping mechanism 44 clamps the second cigarette and releases the first cigarette; if the first cigarette is an irregularly shaped cigarette, the rear clamping mechanism 45 clamps the second cigarette and releases the first cigarette, thus separating the continuously buffered cigarettes into individual cigarettes. When the pneumatic baffle 32 resets and the cigarette detection devices of the front clamping mechanism 44 do not detect any cigarettes, the front clamping mechanism 44 resets, and subsequent cigarettes are conveyed forward. Similarly, when the cigarette detection devices of the rear clamping mechanism 45 do not detect any cigarettes, the rear clamping mechanism 45 resets, and subsequent cigarettes are conveyed forward.

[0053] Furthermore, the cigarette pack adaptive separation device 4 can replace the separation device that clamps the second cigarette pack from the left and right with a separation device that lifts the second and subsequent cigarette packs from the bottom and removes them from the conveying surface.

[0054] like Figure 7 As shown, the photoelectric detection of the cigarette buffer full cup alarm device 5 is arranged at the entrance of the cigarette segmented buffer device 3. When a cigarette in the buffer at the entrance triggers the full cup detection device, the full cup alarm device 5 alarms to prompt manual handling, thus reminding inspection personnel to promptly go from the inspection room to the site for sampling inspection. The full cup alarm device 5 specifically includes a full cup detection device 51, a red and yellow dual-color audible and visual alarm device 52, and an inspection room indicator 53, etc.

[0055] Furthermore, the cigarette buffer full cup alarm device 51 of the cigarette buffer full cup detection device 5 will select appropriate segmented buffering of cigarettes based on the reaction time of the inspector, thereby improving the production management flexibility of the present invention.

[0056] The control system 6 is an electrical control part that supplies power to the present invention, receives detection signals from the present invention, and sends corresponding action commands to the action mechanism of the present invention.

[0057] The usage process of this application is as follows (e.g.) Figures 8-13 (as shown)

[0058] S1. The smoke sample to be inspected enters the sampling buffer channel in a horizontal position from the "sampling rejection outlet" and is transported to the smoke sample detection device 1. This triggers the smoke sample input / output detection device 15. The control system 6 determines whether the smoke sample is standard or irregular based on the triggering status of the irregular smoke sample detection device 13 or the standard smoke sample detection device 14. Specifically: if the standard smoke sample detection device 14 is triggered but the irregular smoke sample detection device 13 is not triggered, the input smoke sample is standard; if both the standard smoke sample detection device 14 and the irregular smoke sample detection device 13 are triggered, the input smoke sample is irregular. After recording the smoke sample type, the control system 6 obtains the smoke sample and actuator status of the smoke sample adaptive processing device 2. If the device has no smoke sample and the actuator is not in the current smoke sample type execution state, the control system 6 sends a corresponding action command to the smoke sample adaptive processing device 2, and the subsequent actuator action is completed. The condition for the first pneumatic baffle 11 to act is that the smoke sample adaptive processing device 2 executes the current smoke sample type and the first-stage smoke sample segment buffer device 3 can buffer the current smoke sample. After the first pneumatic baffle 11 is activated, it releases the smoke, allowing it to continue being conveyed forward. After the smoke input / output detection device 15 is deactivated, the first pneumatic baffle 11 is activated again, blocking subsequent smoke inputs from continuing to be conveyed forward. The above actions are repeated for the next operation.

[0059] S2. The control system 6 issues an action command to the cigarette adaptive processing device 2 based on the cigarette type. Standard cigarettes are input into the cigarette adaptive processing device 2, and the T-shaped flipping mechanism 23, which is in flipping operation mode, flips the standard cigarettes 90°. The standard cigarettes will continue to be conveyed forward in their upright position after flipping. Irregularly shaped cigarettes awaiting inspection are input into the cigarette adaptive processing device 2 and directly pass through the T-shaped flipping mechanism 23, which is in conveying operation mode. The irregularly shaped cigarettes will continue to be conveyed forward in their original flat position. After the cigarette output detection device 24 is deactivated, if there is another operation, the control system 6 will issue an action command after judging the situation.

[0060] S3. A piece of smoke enters the first-stage smoke segment buffer device 3. The second pneumatic baffle 32 is in the blocking position. The smoke is conveyed forward until it is blocked by the second pneumatic baffle 32, forming the first piece of smoke in this buffer segment. Subsequent pieces of smoke continue to be conveyed forward and stacked until the control system 6 determines that the first buffer segment is full. To ensure that the pneumatic baffles of each buffer segment do not hit the smoke, the control system 6 will determine whether the length of the last piece of smoke entering the first buffer segment after stacking will exceed the length of the buffer segment. Specifically, it judges based on the type of smoke to be input. If it is a standard smoke, the standard smoke continues to be input, and the full accumulation detection device 35 is triggered for 5 seconds, and the first-stage buffer smoke is formed. If it is an irregularly shaped smoke, the irregularly shaped smoke stops being conveyed, and the first-stage buffer smoke is formed. After the first-stage buffer smoke is formed, if the previous buffer segment allows smoke to enter, the control system 6 issues a command, the second pneumatic baffle 32 is activated, the blocking is released, and the entire first-stage buffer smoke is conveyed forward. The photoelectric detection device 33 and the accumulation detection device 34 of the second-stage buffer are triggered simultaneously for 5 seconds. When the third-stage buffer allows smoke to enter, the control system 6 issues a command, the second pneumatic baffle 32 moves and releases the obstruction, and the smoke from the second-stage buffer is transported forward to the third-stage buffer until it is transported to the ninth stage. In this way, the smoke is segmented for buffering and transport.

[0061] S4. When a cigarette pack forms a 9-segment buffer in the cigarette pack segment buffer device 3, the first segment buffer triggers the cigarette pack full cup detection device 51 for 10 seconds. The control system 6 gives an alarm signal, the on-site red and yellow dual-color audible and visual alarm device 52 sounds and lights up, and the inspection room prompt device 53 in the inspection room prompts the inspection personnel to go to the site for sampling inspection. At the same time, the first pneumatic baffle 11 does not move and continues to block the input of subsequent cigarette packs until the cigarette pack full cup detection device 51 is deactivated.

[0062] S5. When the inspector performs random inspection, a cigarette output signal is sent to the control system 6. The cigarette adaptive separation device 4, located at the 9th cigarette buffer station of the cigarette segment buffer device 3, is activated to perform the cigarette output operation. Specifically, the following working conditions can be defined:

[0063] (a): The first piece of smoke at the 9th section smoke buffer station is a standard piece of smoke. The standard piece of smoke triggers the standard piece of smoke detection device 42, but does not trigger the irregular piece of smoke detection device 43. The control system 6 determines that the current piece of smoke is a standard piece of smoke and issues an action command. The front clamping mechanism 44 is activated to clamp the second piece of smoke. The second pneumatic baffle 32 is activated to release the first piece of smoke. The first piece of smoke is conveyed forward into the sampling inspection station to wait for sampling inspection. The first piece of smoke triggers the piece of smoke output detection device 41 and deactivates it. The second pneumatic baffle 32 is activated again to block subsequent piece of smoke. The front clamping mechanism 44 is activated again to release the original second piece of smoke. The entire piece of smoke at this station is conveyed forward.

[0064] (b): The first piece of smoke at the 9th section smoke buffer station is an irregularly shaped smoke. The irregularly shaped smoke triggers the irregularly shaped smoke detection device 43 and the standard smoke detection device 42. The control system 6 determines that the current smoke is an irregularly shaped smoke and issues an action command. The clamping mechanism 45 then moves to clamp the second piece of smoke. The second pneumatic baffle 32 moves to release the first piece of smoke. The first piece of smoke is conveyed forward into the sampling inspection station to wait for sampling inspection. The first piece of smoke triggers the smoke output detection device 41 and deactivates it. The second pneumatic baffle 32 moves again to block subsequent smoke. The clamping mechanism 45 moves again to release the original second piece of smoke. The smoke at this station is conveyed forward as a whole.

[0065] (c): Continuous conveying of cigarettes in the cigarette sachet buffering device 3: The continuous output of cigarettes from the 9th cigarette sachet buffering station releases the triggers of the cigarette output detection device 41, the irregular cigarette detection device 43, and the standard cigarette detection device 42. The second pneumatic baffle 32 of the 8th cigarette sachet buffering station is activated, releasing the cigarettes from the 8th cigarette sachet buffering station. The entire 8th cigarette sachet is conveyed forward, releasing the accumulation blocking photoelectric detection device 33, the accumulation in place detection device 34, and the accumulation full detection device 35 of the 8th cigarette sachet buffering station. It also triggers the accumulation blocking photoelectric detection device 33, the accumulation in place detection device 34, and the accumulation full detection device 35 of the 9th cigarette sachet buffering station. The second pneumatic baffle 32 of the 8th cigarette sachet buffering station is activated again to block the cigarettes. The cigarettes from the 8th cigarette sachet buffering station then become the cigarettes from the 9th cigarette sachet buffering station. The cigarettes are then output according to the steps (a) or (b) above for inspection personnel to perform sampling inspection.

[0066] (d): Continuous conveying of cigarettes in the segmented buffer device 3: Following the steps in (c) above, the cigarettes in the subsequent cigarette buffer station move forward one station in sequence. The cigarettes in the first segmented cigarette buffer station are conveyed forward as a whole, and the triggering of the full cup detection device 51 is released. The accumulation and placement detection device 34 of the second segmented cigarette buffer station is triggered. After 5 seconds, the first pneumatic baffle 11 of the cigarette detection device 1 is activated, releasing the cigarettes into the cigarette adaptive processing device 2 for cigarette adaptive processing, so that the cigarettes form a new cigarette buffer segment in the first segmented cigarette buffer device 3.

[0067] After its application, this invention solved the problem of irregularly shaped cigarette packs not being able to be buffered and transported on the same line as standard cigarette packs, realizing fully automated online sampling inspection of irregularly shaped cigarette packs and unifying the cigarette production process. The sampling buffer channel adaptively processes the cigarette packs to be inspected; flipping standard cigarette packs increases the buffer capacity of standard cigarette packs, while not flipping irregularly shaped cigarette packs ensures the stability of the buffer transport of irregularly shaped cigarette packs; the segmented buffer channel effectively separates the cigarette packs to be inspected, reduces the resistance to the start-up transport of buffered cigarette packs, and avoids the increased pressure on the first cigarette pack due to the large number of cigarette packs stacked together, which could damage it or make it difficult to extract from the buffer. The application of this invention also reduces the labor intensity of manual operation in automated production lines, improves the efficiency of manual operation, and solves a series of problems such as the easy damage to cigarette packs in the buffer channel, safety hazards, and low level of informatization, thus ensuring the level of automation and informatization of production in cigarette manufacturing enterprises.

[0068] This invention is applied to the daily production scheduling of finished product warehousing in the cigarette packaging workshop of a cigarette factory. This achievement can realize the conveying and buffering functions of cigarettes of different shapes and sizes, solve the problem that irregularly shaped cigarettes and standard cigarettes cannot be automatically inspected online when produced on the same line, improve the automation level of cigarette manufacturing enterprises, and has good market promotion and application prospects in cigarette industrial enterprises.

[0069] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various different choices and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention is defined by the claims and their equivalents.

The control system is used to supply power and operate the controlled component smoke detection device, the component smoke adaptive processing device, the component smoke segmentation buffer device, the component smoke adaptive separation device, and the component smoke buffer full cup alarm device.

2. The adaptive fully automatic cigarette pack tobacco buffer channel according to claim 1, characterized in that, The three sets of through-beam photoelectric detection devices are used to detect cigarettes that are lying flat and entering the cigarette detection device. The type of cigarette is determined by the height of the cigarette. The three sets of through-beam photoelectric detection devices are arranged from top to bottom as follows: irregularly shaped cigarette detection device, standard cigarette detection device, and cigarette input / output detection device. When the standard cigarette detection device is triggered but the irregularly shaped cigarette detection device is not triggered, it is determined to be a standard cigarette; when both are triggered, it is determined to be an irregularly shaped cigarette.

3. The adaptive fully automatic cigarette pack tobacco buffer channel according to claim 1, characterized in that, The first pneumatic baffle is located at the front end of the smoke detection device and is used to allow smoke in the current section to pass when there is a signal that allows smoke in the current section.

4. The adaptive fully automatic cigarette pack tobacco buffer channel according to claim 1, characterized in that, The adaptive cigarette handling device includes: a horizontal conveying mechanism, a T-shaped flipping mechanism, and a cigarette output detection device. When a standard cigarette enters the horizontal conveying mechanism of the adaptive cigarette handling device, the T-shaped flipping mechanism, which is in the flipping working state, flips the standard cigarette by 90°, and the standard cigarette continues to be conveyed forward in the flipped posture. When an irregularly shaped cigarette to be inspected enters the horizontal conveying mechanism of the adaptive cigarette handling device, it directly passes through the T-shaped flipping mechanism, which is in the conveying working state, and the irregularly shaped cigarette continues to be conveyed forward in the original posture.

5. The adaptive fully automatic cigarette pack buffer channel according to claim 1, characterized in that, The adaptive cigarette processing device further includes: a flipping position detection device and a cigarette output detection device. The flipping position detection device is used to detect whether the T-shaped flipping mechanism has flipped the standard cigarette in place, and the cigarette output detection device is used to detect whether the cigarette is output from the adaptive processing device.

6. The adaptive fully automatic cigarette pack tobacco buffer channel according to claim 1, characterized in that, The horizontal conveying mechanism is a long shaft fitted with a pulley. The pulley is driven to rotate by the friction between the long shaft and the inner hole of the pulley. The pulley and the roller are connected by a round belt, which drives the roller to rotate for conveying. During the conveying process, the cigarette is blocked. The friction between the cigarette and the roller will prevent the roller from rotating, thus avoiding the bottom of the cigarette from rubbing against the rotating roller and wearing down the bottom of the cigarette box.

7. The adaptive fully automatic cigarette pack tobacco buffer channel according to claim 1, characterized in that, The adaptive separation device for cigarettes includes: a cigarette output detection device, a standard cigarette detection device, an irregularly shaped cigarette detection device, a front clamping mechanism, and a rear clamping mechanism. Based on the cigarette type detected by the standard and irregularly shaped cigarette detection devices, if the first cigarette is a standard cigarette, the front clamping mechanism clamps the second cigarette and releases the first cigarette; if the first cigarette is an irregularly shaped cigarette, the rear clamping mechanism clamps the second cigarette and releases the first cigarette. When the second pneumatic baffle resets and the front clamping mechanism's photoelectric sensor does not detect any cigarettes, the front clamping mechanism resets, and subsequent cigarettes are conveyed forward. Similarly, if the rear clamping mechanism's photoelectric sensor does not detect any cigarettes, the rear clamping mechanism resets, and subsequent cigarettes are conveyed forward.

8. The adaptive fully automatic cigarette pack tobacco buffer channel according to claim 1, characterized in that, The full-cup alarm device for cigarette packs includes: a full-cup detection device, a red and yellow dual-color audible and visual alarm device, and an inspection room indicator. When a cigarette pack forms a 9-segment buffer in the cigarette pack segment buffer device, the first segment buffer triggers the full-cup detection device for 10 seconds, the control system issues an alarm signal, the on-site red and yellow dual-color audible and visual alarm device sounds and lights up, and the inspection room indicator prompts the inspectors to go to the site for sampling inspection. At the same time, the first pneumatic baffle does not move, continuously blocking the input of subsequent cigarette packs until the triggering state of the full-cup detection device is deactivated.

9. The adaptive fully automatic cigarette pack tobacco buffer channel according to claim 8, characterized in that, When the inspectors conduct random inspections, they send a cigarette output signal to the control system. The cigarette adaptive separation device located at the 9th cigarette buffer station of the cigarette segment buffer device then activates and performs the cigarette output operation.
