Description

Technical Field

[0001] This invention relates to the field of tobacco pack conveying technology, and in particular to a stacked tobacco pack flat conveying device and its usage method. Background Technology

[0002] In FOCKE packaging units, cigarette packs are often conveyed in a stacked manner. During the conveying process, due to asynchronous contact and uneven pressure between the upper and lower conveyor belts, misalignment of the upper and lower cigarette packs can easily occur. This misalignment not only increases the risk of the upper cigarette pack slipping but also prevents the QR code reader from accurately focusing and recognizing the code, seriously affecting production efficiency and product quality.

[0003] Existing technologies typically employ left-right opposing, elastically resettable smoke baffles to align the smoke packs. However, this approach has the following problems: First, the smoke baffles perform linear extension and retraction movements, and their contact with and detachment from the smoke packs occur sequentially during release, making it impossible to guarantee synchronized movement of the upper and lower smoke packs and potentially causing secondary misalignment. Second, this approach relies on the thrust of subsequent smoke packs to force the smoke baffles to retract, lacking proactive and intelligent control logic, which can easily lead to blockages due to untimely action in high-speed continuous production scenarios. Third, the device lacks effective error prevention and emergency mechanisms, and cannot adaptively handle abnormal incoming materials. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to overcome the shortcomings of the related technology. The present invention provides a stacked tobacco pack flat conveying device and a method of using it.

[0005] This invention provides the following technical solution: A stacked cigarette pack flat conveying device includes a frame, a conveying module, a leveling module, a detection module, and a control module.

[0006] The conveying module is mounted on the frame and includes an upper conveyor belt and a lower conveyor belt. The upper conveyor belt is arranged parallel to the lower conveyor belt. The lower conveyor belt is used to convey stacked cigarette packs, and the upper conveyor belt is used to vertically limit the stacked cigarette packs on the lower conveyor belt. The leveling module is mounted on the frame and located above the lower conveyor belt. The leveling module includes a stop member with a leveling portion. The leveling module can drive the stop member to swing relative to the frame, thereby causing the leveling portion to block and level the stacked cigarette packs on the lower conveyor belt. The swing axis of the stop member is parallel to the lower conveyor belt. The width direction is parallel; the detection module is mounted on the frame, and the detection module includes a pre-detection unit and a post-detection unit. The pre-detection unit is used to detect the leveling status of stacked cigarette packs located upstream of the leveling section on the lower conveyor belt after being blocked, and the post-detection unit is used to detect the passage of stacked cigarette packs located downstream of the leveling section on the lower conveyor belt; the control module is used to be electrically connected to the leveling module and the detection module respectively; the control module receives data transmitted from the detection module, and then sends a control signal to the leveling module, so that the leveling module controls and drives the blocking component to swing relative to the frame.

[0007] As a further improvement to the above technical solution, the detection module also includes a barcode scanning device, which is mounted on the frame and electrically connected to the control module. The barcode scanning device is used to scan the product codes on the stacked cigarette packs that are blocked and leveled by the leveling module on the lower conveyor belt.

[0008] As a further improvement to the above technical solution, the detection module also includes a blockage detection unit, which is used to detect the passage of stacked cigarette packs located upstream of the detection area of ​​the preceding detection unit on the lower conveyor belt.

[0009] As a further improvement to the above technical solution, the leveling module also includes a drive motor and a connecting rod. The drive motor is fixedly mounted on the frame. One end of the connecting rod is connected to the drive motor, and the other end of the connecting rod is assembled and connected to the stop member. The end face of the stop member facing the opposite direction to the conveying direction of the lower conveyor belt is used to form a leveling part.

[0010] As a further improvement to the above technical solution, the lower conveyor belt has a central sectional surface parallel to its conveying direction, and two stopping members are symmetrically provided with respect to this central sectional surface.

[0011] As a further improvement to the above technical solution, the end of the connecting rod away from the drive motor is provided with a connecting seat corresponding to the stop member. The stop member is telescopically mounted on the connecting seat, and the connecting seat is provided with an adjusting member, which is used to limit and adjust the relative position of the stop member and the connecting seat.

[0012] As a further improvement to the above technical solution, the extension and retraction direction of the blocking member relative to the connecting seat is perpendicular to the swing axis of the connecting rod.

[0013] As a further improvement to the above technical solution, the stopping member is provided with an air jet assembly, the air jet direction of which is opposite to the conveying direction of the lower conveyor belt.

[0014] As a further improvement to the above technical solution, the jet assembly includes a jet seat, and the jet seat is provided with a first nozzle and a second nozzle in sequence along the vertical direction. The first nozzle and the second nozzle are respectively connected to an independent gas delivery device through an air pipe, and the gas delivery device is electrically connected to the control module. The first nozzle is used to blow airflow to the tobacco packs on the upper side of the stacked tobacco packs on the lower conveyor belt, and the second nozzle is used to blow airflow to the tobacco packs on the lower side of the stacked tobacco packs on the lower conveyor belt.

[0015] As a further improvement to the above technical solution, the first nozzle and the second nozzle are each provided with multiple nozzles along the width direction of the lower conveyor belt.

[0016] The present invention also provides a method of using a stacked tobacco bale flat conveyor, wherein the method of using the stacked tobacco bale flat conveyor of any of the above-mentioned methods includes: The blocking component is controlled to swing relative to the frame by using the leveling component, so that the leveling part on the blocking component blocks the conveying area of ​​the lower conveyor belt; Stacked cigarette packs are placed on the lower conveyor belt for transportation, and the blocking parts on the stopper block and level the stacked cigarette packs. When the preceding detection unit detects that the stacked cigarette packs blocked by the blocking component on the lower conveyor belt are normally aligned, it sends a signal to the control module. The control module sends a signal to the scanning device, which scans and records the product code on the stacked cigarette packs that are blocked by the blocking device; after the scanning device completes the scanning, it sends a signal to the control module. The control module sends a signal to the leveling component, which controls the blocking component to swing relative to the frame, thus releasing the obstruction of the stacked cigarette packs that have been scanned. The subsequent detection unit detects that the stacked cigarette packs send a signal through the subsequent control module; The control module sends a signal to the leveling assembly, which controls the stopper to swing relative to the frame, so that the leveling part on the stopper blocks the conveying area of ​​the lower conveyor belt. The stacked cigarette packs are conveyed to the next production process via the lower conveyor belt; If the stacked cigarette packs blocked by the blocking device are not aligned, the blockage detection unit will detect that there are stacked cigarette packs continuously staying in the detection area and send a signal to the control module. The control module simultaneously sends signals to the leveling component and the subsequent rejection equipment. The leveling component controls the blocking component to swing relative to the frame, releasing the obstruction of stacked cigarette packs that are not leveled or scanned. The subsequent detection unit detects stacked cigarette packs that are not leveled or scanned and sends a signal through the subsequent control module. The control module sends a signal to the leveling assembly, which controls the stopper to swing relative to the frame, so that the leveling part on the stopper blocks the conveying area of ​​the lower conveyor belt. Unaligned and unscanned stacked cigarette packs are removed from the conveyor belt by a rejection device during the conveyor belt transport process.

[0017] Compared with related technologies, the advantages of this invention are: The stacked cigarette pack flat conveying device provided by this invention, during the initial stage of device startup, controls the blocking component to swing relative to the frame. This swinging process allows the blocking part on the blocking component to align with the conveying area of ​​the lower conveyor belt, forming a blocking barrier.

[0018] Next, workers place the stacked cigarette packs onto the lower conveyor belt. At this point, the upper and lower conveyor belts work together, using the friction generated by their movement to propel the stacked cigarette packs forward. When the stacked cigarette packs reach the leveling section of the stopping mechanism, the leveling section aligns the packs, ensuring they are neatly stacked and facilitating subsequent processing.

[0019] During this process, the preceding detection unit of the detection module can monitor the leveling status of the stacked cigarette packs that are blocked by the stopper on the lower conveyor belt in real time. Once the leveling of the stacked cigarette packs is detected, the preceding detection unit sends a signal to the control module. Upon receiving this signal, the control module immediately issues a command to the leveling component, which then controls the stopper to swing in the opposite direction relative to the frame, thereby releasing the obstruction of the neatly stacked cigarette packs. In this way, the leveled stacked cigarette packs can smoothly continue to move forward with the lower conveyor belt to enter the next processing step.

[0020] In addition, the subsequent detection unit of the detection module also continuously monitors the stacked cigarette packs. When it detects that the stacked cigarette packs have completely passed through its detection area, it sends a signal to the control module. The control module responds again, sending a command to the leveling component. The leveling component controls the blocking element to swing relative to the frame, causing the leveling part on the blocking element to block the conveyor area of ​​the lower conveyor belt again, preparing for the arrival of the next set of stacked cigarette packs, realizing a cyclical blocking and leveling operation.

[0021] Through the detailed description of the working process above, this invention achieves continuous and automated leveling and transport of stacked cigarette packs. This innovative design not only greatly simplifies the operation process and reduces manual intervention, but also significantly improves the production and processing efficiency of stacked cigarette packs, providing strong support for automated production in the tobacco industry.

[0022] It is worth mentioning that by setting the swing axis of the stopper relative to the frame to be parallel to the width direction of the lower conveyor belt, this ingenious design allows the various blocking positions of the leveling section to synchronously separate from the blocked surfaces of the stacked cigarette packs when the stopper swings to release the blocking state. This synchronous separation effectively avoids misalignment problems that may occur when the cigarette packs stacked vertically are not synchronized due to asynchronous blocking. This ensures that the stacked cigarette packs remain reliably level even when the stopper releases the blocking state, providing a stable and neat stack of cigarette packs for subsequent processing steps, further ensuring subsequent processing efficiency and quality.

[0032] Combination Figures 1 to 3 As shown, an embodiment of the present invention provides a stacked cigarette pack flat conveying device, including a frame 100, a conveying module 200, a leveling module 300, a detection module 400, and a control module.

[0033] The conveying module 200 is mounted on the frame 100. The conveying module 200 includes an upper conveyor belt 210 and a lower conveyor belt 220. The upper conveyor belt 210 is parallel to the lower conveyor belt 220. The lower conveyor belt 220 is used to convey stacked cigarette packs 500, and the upper conveyor belt 210 is used to vertically limit the stacked cigarette packs 500 on the lower conveyor belt 220. The leveling module 300 is mounted on the frame 100 and located above the lower conveyor belt 220. The leveling module 300 includes a blocking member 310 with a leveling portion 311. The leveling module 300 can drive the blocking member 310 to swing relative to the frame 100, thereby causing the leveling portion 311 to block and level the stacked cigarette packs 500 on the lower conveyor belt 220. The swing axis of the blocking member 310 is parallel to the width direction of the lower conveyor belt 220. The detection... Module 400 is mounted on the frame 100. The detection module 400 includes a pre-detection unit 410 and a post-detection unit 420. Each detection unit of the detection module 400 can specifically use an infrared sensor to ensure the sensitivity and accuracy of the detection process. The pre-detection unit 410 is used to detect the leveling status of stacked cigarette packs 500 located upstream of the leveling section 311 on the lower conveyor belt 220 after being blocked. The post-detection unit 420 is used to detect the passage of stacked cigarette packs 500 located downstream of the leveling section 311 on the lower conveyor belt 220. The control module is electrically connected to the leveling module 300 and the detection module 400 respectively. The control module receives data transmitted from the detection module 400 and then sends a control signal to the leveling module 300, causing the leveling module 300 to control and drive the blocking member 310 to swing relative to the frame 100.

[0034] In the stacked cigarette pack flat conveying equipment provided in this embodiment, during the initial stage of equipment startup, the leveling component controls the blocking member 310 to swing relative to the frame 100. This swinging process allows the leveling part 311 on the blocking member 310 to align with the conveying area of ​​the lower conveyor belt 220, forming a blocking barrier.

[0035] Next, the workers place the stacked cigarette packs onto the lower conveyor belt 220. At this time, the upper conveyor belt 210 and the lower conveyor belt 220 work together, using the friction generated by their movement to push the stacked cigarette packs 500 forward. When the stacked cigarette packs 500 reach the leveling part 311 of the stopping part 310, the leveling part 311 can level the stacked cigarette packs 500, ensuring that the cigarette packs are stacked neatly and facilitating subsequent processing.

[0036] During this process, the preceding detection unit 410 of the detection module 400 can sense the leveling status of the stacked cigarette packs 500 blocked by the stopper 310 on the lower conveyor belt 220 in real time. Once it is detected that the stacked cigarette packs 500 have been leveled, the preceding detection unit 410 will send a signal to the control module. After receiving this signal, the control module will immediately issue a command to the leveling component, which will then control the stopper 310 to swing in the opposite direction relative to the frame 100, thereby releasing the obstruction of the now neatly stacked cigarette packs 500. In this way, the leveled stacked cigarette packs 500 can smoothly continue to move forward with the lower conveyor belt 220 to enter the next processing step.

[0037] In addition, the subsequent detection unit 420 of the detection module 400 also continuously monitors the stacked cigarette packs 500. When it detects that the stacked cigarette packs 500 have completely passed through its detection area, it sends a signal to the control module. The control module responds again and sends a command to the leveling component. The leveling component controls the blocking member 310 to swing relative to the frame 100, so that the leveling part 311 on the blocking member 310 blocks the conveying area of ​​the lower conveyor belt 220 again, preparing for the arrival of the next set of stacked cigarette packs 500, realizing the cyclical blocking and leveling operation.

[0038] Through the detailed description of the working process above, this embodiment achieves continuous and automated leveling and transport of stacked cigarette packs 500. This innovative design not only greatly simplifies the operation process and reduces manual intervention, but also significantly improves the production and processing efficiency of stacked cigarette packs 500, providing strong support for automated production in the tobacco industry.

[0039] It is worth mentioning that by setting the swing axis of the stopper 310 relative to the frame 100 to be parallel to the width direction of the lower conveyor belt 220, this ingenious design allows the various blocking positions of the leveling part 311 to synchronously separate from the blocked surface of the stacked cigarette packs 500 when the stopper 310 swings to release the blocking state. This synchronous separation effectively avoids the misalignment problem that may occur when the cigarette packs stacked in the vertical direction are not blocked synchronously. It ensures that the stacked cigarette packs 500 remain reliably level even when the stopper 310 releases the blocking state, providing a stable and neat stack of cigarette packs for subsequent processing steps, further ensuring subsequent processing efficiency and quality.

[0040] In some specific embodiments, the detection module 400 further includes a barcode scanning device 430, which is mounted on the rack 100. The control module is electrically connected to the barcode scanning device 430 to transmit and interact with signals.

[0041] Specifically, the main function of the barcode scanning device 430 is to scan the product codes on the stacked cigarette packs 500 that are blocked and leveled by the leveling module 300 on the lower conveyor belt 220. This design aims to obtain relevant information about the stacked cigarette packs 500, such as production batch and specifications, by scanning the product codes, thus providing data support for subsequent production management.

[0042] During actual operation, the preceding detection unit 410 continuously monitors the status of the stacked cigarette packs 500 on the lower conveyor belt 220. Once it detects that the stacked cigarette packs 500 have been successfully blocked and leveled by the blocking component 310, the preceding detection unit 410 will immediately send a clear signal to the control module, informing the control module that the stacked cigarette packs 500 are in a scannable state.

[0043] Upon receiving this signal, the control module will respond quickly and send a command to the scanning device 430 to start scanning. Upon receiving the command, the scanning device 430 will immediately scan the product codes on the stacked cigarette packs 500 that are blocked by the blocking element 310, and accurately record the scanned information. This process ensures that the information of each stack of cigarette packs 500 can be accurately captured and stored.

[0044] After completing the scanning task, the scanning device 430 sends a completion signal to the control module, informing the control module that the scanning work has ended and subsequent processes can proceed. Upon receiving this signal, the control module continues to control the operation of the equipment according to the preset program, such as releasing the obstruction of the stop 310 and pushing the stacked cigarette packs 500 forward.

[0045] By adding a barcode scanner 430 and linking it with the control module, this stacked cigarette pack leveling conveyor not only accurately records the leveling process of the stacked cigarette packs 500, but also provides accurate data support for operators during subsequent production processing. Operators can precisely operate and adjust the equipment based on the information recorded by the barcode scanner 430, ensuring that subsequent production processes proceed smoothly according to predetermined requirements, thereby effectively improving production quality and efficiency.

[0046] In some specific embodiments, the detection module 400 further includes a blockage detection unit 440, which is used to detect the passage of stacked cigarette packs 500 on the lower conveyor belt 220 upstream of the detection area of ​​the preceding detection unit 410. Specifically, the working process of the blockage detection unit 440 is as follows: During normal operation of the equipment, when stacked cigarette packs 500 blocked by the blocking component 310 fail to align successfully, these misaligned stacked cigarette packs 500 may remain on the lower conveyor belt 220, thus creating a potential blockage risk. At this time, the blockage detection unit 440 will immediately detect this abnormality within its detection area, that is, detect that stacked cigarette packs 500 remain motionless.

[0047] Once the blockage detection unit 440 confirms a blockage risk, it quickly sends an emergency signal to the control module, informing it that there are misaligned stacked cigarette packs 500 on the lower conveyor belt 220, which may cause a blockage. Upon receiving this signal, the control module immediately initiates an emergency response procedure. It simultaneously sends control signals to the leveling assembly and subsequent rejection equipment, instructing the leveling assembly to control the stopper 310 to swing relative to the frame 100, thereby releasing the misaligned stacked cigarette packs 500 that have not yet been scanned, allowing these abnormal cigarette packs to continue moving with the lower conveyor belt 220.

[0048] Subsequently, the follow-up detection unit 420 closely monitors the movement of these stacked cigarette packs 500 that are not aligned or scanned. Once it detects that these abnormal cigarette packs have completely passed through their detection area, the follow-up detection unit 420 immediately sends a confirmation signal to the control module, informing the control module that the abnormal cigarette packs have left the critical area and that subsequent normal processes can proceed.

[0049] Meanwhile, under the command of the control module, the rejection equipment is ready. When stacked cigarette packs 500 that are not leveled or scanned are conveyed to the rejection equipment location by the lower conveyor belt 220, the rejection equipment will quickly move and accurately reject these abnormal cigarette packs from the conveyor belt. These rejected cigarette packs will be left for further processing by other specialized equipment or manually to ensure that they do not interfere with subsequent production processes.

[0050] By adding a blockage detection unit 440 and implementing its linkage control with the control module, the leveling component, and the rejection device, the stacked cigarette pack leveling conveyor can not only effectively detect and handle blockage problems during the conveying process, but also ensure the continuous operation of the leveling process, avoiding production interruptions caused by abnormal situations, thereby significantly improving overall production efficiency.

[0051] In some specific embodiments, the leveling module 300 further includes a drive motor 320 and a connecting rod 330. The drive motor 320 is fixedly mounted on the frame 100. One end of the connecting rod 330 is connected to the drive motor 320, and the other end is assembled with the stop member 310. The end face of the stop member 310 facing the opposite direction of the conveying direction of the lower conveyor belt 220 forms a leveling part 311. This leveling part 311 is a key part that directly contacts and blocks the stacked cigarette packs 500. Its surface is flat and has a certain strength, which can provide sufficient resistance when blocking the stacked cigarette packs 500 to ensure that the stacked cigarette packs 500 can be accurately leveled. In actual operation, when the stop member 310 needs to perform leveling operation, the drive motor 320 starts and outputs power according to the preset rotation direction and speed. This power is transmitted to the connecting rod 330 through the transmission connection, and the connecting rod 330 begins to rotate under the drive of the drive motor 320. Since the connecting rod 330 is assembled with the stop member 310, the rotation of the connecting rod 330 will cause the stop member 310 to swing together. As the stop member 310 swings, its leveling part 311 gradually moves to the conveying area of ​​the lower conveyor belt 220, blocking the stacked cigarette packs 500 that are being conveyed, stopping the stacked cigarette packs 500 from moving and performing a leveling operation.

[0052] Through the coordinated operation of the drive motor 320, connecting rod 330, and stopping component 310, the drive motor 320 can precisely and efficiently drive the connecting rod 330 to swing the stopping component 310, thereby enabling the blocking part 311 of the stopping component 310 to perform accurate and timely blocking action. This design not only ensures the high efficiency of the stopping component 310's action, enabling it to complete the swinging and blocking operations in a short time and improving the equipment's operating efficiency, but also guarantees the reliability of the action, reducing errors in the stopping component 310's action caused by mechanical failures or transmission problems, providing a strong guarantee for the leveling and conveying of stacked cigarette packs 500.

[0053] In some specific embodiments, the lower conveyor belt 220 has a central sectional surface parallel to its conveying direction, and two blocking members 310 are symmetrically provided with respect to this central sectional surface; in the actual process of blocking and leveling stacked cigarette packs 500, when the stacked cigarette packs 500 are conveyed forward along the lower conveyor belt 220, the two symmetrically distributed blocking members 310 will play a role simultaneously.

[0054] Because the blocking elements 310 are symmetrically arranged, the forces they exert on the stacked tobacco packs 500 are spatially balanced. When blocking the stacked tobacco packs 500, the two blocking elements 310 block the tobacco packs from both sides of the central sectional plane, preventing the tobacco packs from shifting or tilting to one side when subjected to resistance. This symmetrical force distribution ensures that the stacked tobacco packs 500 remain stable during the blocking and leveling process, avoiding problems such as tobacco pack shaking and collapse caused by uneven force distribution, and greatly improving the reliability of the blocking and leveling.

[0055] Meanwhile, the two symmetrical stopping components 310 can also jointly bear the force required to block the stacked tobacco packs 500. Compared with a single stopping component 310, they can more effectively disperse and bear the impact force of the tobacco packs, reduce the risk of damage to a single stopping component 310 due to excessive force, extend the service life of the stopping component 310, and further ensure the stability and continuity of the entire blocking and leveling process.

[0056] In some specific embodiments, the end of the connecting rod 330 away from the drive motor 320 is provided with a connecting seat 331 corresponding to the stop member 310. The stop member 310 is telescopically mounted on the connecting seat 331. The connecting seat 331 is provided with an adjusting member 332. The adjusting member 332 is used to limit the adjustment of the relative position between the stop member 310 and the connecting seat 331, such as by rotating the adjusting screw or moving the adjusting slider, to change the degree of telescopic extension of the stop member 310 on the connecting seat 331.

[0057] In actual production, when faced with cigarette packs of different stacking heights, operators first observe the actual situation of the stacked cigarette packs 500 to determine the approximate position of their horizontal center line. Then, by operating the adjusting component 332 on the connecting seat 331, the extension and retraction of the blocking component 310 is slowly adjusted until the center line of the leveling part 311 of the blocking component 310 gradually aligns with the horizontal center line of the stacked cigarette packs 500. During the adjustment process, professional measuring tools, such as a level, can be used to ensure the accuracy of the adjustment.

[0058] Once the horizontal center line of the blocking part 311 of the blocking component 310 is aligned with the horizontal center line of the stacked cigarette packs 500, the blocking component 310 can block the stacked cigarette packs 500 at the most suitable position and angle during the subsequent leveling and alignment process, ensuring accurate leveling. This design not only ensures the effectiveness of the leveling and alignment process of the stacked cigarette packs 500, enabling them to maintain a neat and stable state during transportation, but also greatly improves the reliability of the operation, reducing the occurrence of leveling failures and cigarette pack tipping caused by improper positioning of the blocking component 310, thus providing a strong guarantee for the smooth operation of the entire production process.

[0059] In some specific embodiments, the extension and retraction direction of the stop member 310 relative to the connecting seat 331 is perpendicular to the swing axis of the connecting rod 330, which helps to reduce the space required for assembling components such as the connecting rod 330 and the drive motor 320, and improves the integration level of the equipment.

[0060] In some specific embodiments, the blocking member 310 is equipped with a jetting assembly 600, the jetting direction of which is opposite to the conveying direction of the lower conveyor belt 220. In actual working scenarios, after the stacked cigarette packs 500 are successfully blocked and leveled by the blocking member 310, they will be in a relatively stable state. Subsequently, the drive motor 320 starts to operate, driving the blocking member 310 to swing through the connecting rod 330, gradually moving it away from the leveled stacked cigarette packs 500, thereby releasing the obstruction of the cigarette packs. At this critical moment when the blocking member 310 releases the obstruction, the jetting assembly 600 immediately starts.

[0061] After the jet assembly 600 is activated, it blows an airflow with a certain pressure and velocity onto the stacked smoke packs 500 according to a preset jet direction. Since the jet direction is opposite to the conveying direction of the lower conveyor belt 220, the stacked smoke packs 500 will be impacted by the reverse airflow at the moment they lose contact with the baffle 311. This airflow can provide an additional force to the stacked smoke packs 500, compensating for any posture changes that may occur due to the loss of support from the baffle 311.

[0062] Specifically, when the stacked tobacco packs 500 detach from the leveling section 311, without the action of the jet assembly 600, the tobacco packs might slightly tilt, sway, or partially misalign due to their own weight, the friction of the conveyor belt, and other factors. The airflow from the jet assembly 600 can counteract these adverse factors, allowing the stacked tobacco packs 500 to maintain their relatively flat and stable posture after detaching from the leveling section 311.

[0063] This design further ensures the flatness of each cigarette pack during subsequent transportation. Maintaining a flat posture, the stacked cigarette packs 500 move more stably on the lower conveyor belt 220, reducing collisions and jamming caused by poor pack posture, thus improving the smoothness and efficiency of the entire transportation process. Simultaneously, it reduces the risk of packaging damage and product quality degradation due to uneven packs, providing a strong guarantee for high-quality production.

[0064] In some specific embodiments, the jet assembly 600 includes a jet base 610, which is vertically arranged with a first nozzle 611 and a second nozzle 612. The first nozzle 611 and the second nozzle 612 are respectively connected to an independent gas delivery device via air pipes. The gas delivery device is electrically connected to the control module, which allows the control module to precisely control the start-up, stop, and output airflow parameters, such as pressure and flow rate, of the gas delivery device according to actual working requirements. The first nozzle 611 is used to blow airflow onto the tobacco packs on the upper side of the stacked tobacco packs 500 on the lower conveyor belt 220, and the second nozzle 612 is used to blow airflow onto the tobacco packs on the lower side of the stacked tobacco packs 500 on the lower conveyor belt 220. This design facilitates providing pulsed airflow with different pressures and timings for tobacco packs at different heights. The control module can precisely control the gas delivery device to deliver airflow with different pressures to the first nozzle 611 and the second nozzle 612 according to a preset program or real-time monitoring of the stacked tobacco packs 500, and can perform pulsed blowing according to a specific timing sequence. For example, at the instant the stacked tobacco pack 500 just leaves the baffle 311, the first nozzle 611 and the second nozzle 612 are activated simultaneously, but the airflow pressure output by the first nozzle 611 is larger and the airflow pressure output by the second nozzle 612 is smaller. As the stacked tobacco pack 500 continues to be conveyed on the lower conveyor belt 220, the airflow pressure and blowing sequence of the two nozzles are adjusted in a timely manner according to the changes in its posture.

[0065] Specifically, extensive experiments and practical verification have shown that the airflow pressure required to maintain the posture of the upper cigarette packs 500 is greater than that required to maintain the posture of the lower cigarette packs 500. This airflow pressure setting better matches the actual stress conditions and posture changes of the stacked cigarette packs 500 at different heights, thus better maintaining the flat posture of the stacked cigarette packs 500 during subsequent transportation, effectively reducing various problems caused by poor cigarette pack posture, and improving the stability of the entire production process and product quality.

[0066] In some specific embodiments, multiple first nozzles 611 and second nozzles 612 are provided along the width direction of the lower conveyor belt 220, which facilitates ensuring that a uniform and reliable airflow is provided to the tobacco packs at each height, and further ensures the reliability of the stacked tobacco packs 500 in maintaining their posture.

[0067] The present invention also provides a method of using a stacked tobacco bale flat conveyor, wherein the stacked tobacco bale flat conveyor of any of the above-mentioned methods is illustrated in the flowchart below. Figure 4 As shown, the process includes the following: In the actual production process, the leveling assembly is first used to control the oscillation of the stopper 310 relative to the frame 100. As a key power and control component, the leveling assembly drives the stopper 310 to move along a predetermined trajectory and angle. As the stopper 310 oscillates, the leveling section 311 mounted on it gradually moves to the conveying area of ​​the lower conveyor belt 220, blocking the conveying area and preparing for the subsequent leveling operation of the stacked cigarette packs 500.

[0068] Next, the stacked cigarette packs are placed on the lower conveyor belt 220, which then starts operating, transporting the stacked cigarette packs 500 forward. When the stacked cigarette packs 500 reach the position of the stopper 310, the leveling part 311 on the stopper 310 will block the stacked cigarette packs 500, stopping their forward movement and performing a leveling operation to ensure that the stacked cigarette packs 500 are neatly and stably arranged.

[0069] At this point, the preceding detection unit 410 begins to function. The preceding detection unit 410 can monitor the situation on the lower conveyor belt 220 in real time. When it detects that the stacked cigarette packs 500 blocked by the stopper 310 on the lower conveyor belt 220 have completed the leveling operation, it will immediately send a signal to the control module.

[0070] Upon receiving the signal from the preceding detection unit 410, the control module reacts quickly by sending a signal to the barcode scanning device 430. Upon receiving the signal, the barcode scanning device 430 immediately activates and scans and records the product codes on the stacked cigarette packs 500 that are blocked by the stopper 310. The product codes contain detailed information about the cigarette packs, such as production date, batch number, and specifications. By scanning and recording this information, product traceability and management can be achieved. After completing the scanning operation, the barcode scanning device 430 sends a scanning completion signal to the control module, informing the control module that the scanning work has been completed.

[0071] After receiving a signal from the barcode scanner 430 indicating that scanning is complete, the control module sends another signal to the leveling assembly. Following the control module's instructions, the leveling assembly controls the stopper 310 to swing relative to the frame 100, releasing it from obstruction of the scanned stacked cigarette packs 500. At this point, the stacked cigarette packs 500 can continue to move forward on the lower conveyor belt 220.

[0072] The subsequent detection unit 420 monitors the passage of the stacked cigarette packs 500 in real time. Once the subsequent detection unit 420 detects that the stacked cigarette packs 500 have completely passed, it sends a signal to the control module. Upon receiving the signal from the subsequent detection unit 420, the control module sends another signal to the leveling assembly. The leveling assembly controls the stop member 310 to swing relative to the frame 100, causing the leveling part 311 on the stop member 310 to again block the conveying area of ​​the lower conveyor belt 220, preparing for the leveling and scanning operation of the next set of stacked cigarette packs 500. The leveled and scanned stacked cigarette packs 500 then smoothly enter the next production process with the lower conveyor belt 220 to continue subsequent processing and handling.

[0073] However, some abnormal situations may occur during actual production. For example, when the stacked cigarette packs 500 blocked by the stopper 310 are not level, the blockage detection unit 440 will detect that the stacked cigarette packs 500 are continuously stuck in its detection area. The blockage detection unit 440 is usually located upstream of the stopper 310 and can promptly sense the status of the stacked cigarette packs 500. Once an abnormality is detected, it will immediately send a blockage signal to the control module.

[0074] After receiving the signal from the blockage detection unit 440, the control module simultaneously sends signals to the leveling assembly and the subsequent rejection equipment. Following the instructions from the control module, the leveling assembly controls the blocking component 310 to swing relative to the frame 100, releasing the obstruction of the stacked cigarette packs 500 that are not leveled or scanned, allowing these abnormally stacked cigarette packs 500 to continue moving forward and preventing blockage of the conveyor equipment.

[0075] The subsequent detection unit 420 continuously monitors the passage of these stacked cigarette packs 500 that are not leveled or scanned. Once they have passed completely, it sends a signal to the control module. Upon receiving the signal from the subsequent detection unit 420, the control module sends another signal to the leveling assembly. The leveling assembly controls the stop member 310 to swing relative to the frame 100, causing the leveling portion 311 on the stop member 310 to re-block the conveying area of ​​the lower conveyor belt 220, restoring the normal blocking state and preparing for subsequent normal production.

[0076] Those stacked cigarette packs 500 that are not leveled or scanned will be removed from the conveyor belt 220 by a rejection device. The rejection device usually uses robotic arms, pneumatic devices, etc., to accurately and quickly separate abnormal stacked cigarette packs 500 from the conveyor belt, so that they can be processed by other equipment or manually, thus avoiding affecting the normal operation of the entire production process.
