The anti-overturning device comprises a photoelectric detection unit (1), a horizontal pushing unit (2), a lifting platform (3) and an anti-overturning device support (4).

Description

Technical Field

[0001] This invention belongs to the field of cigarette production machinery technology, specifically relating to an anti-tipping device and method for a YJ36 filter rod loading machine. Background Technology

[0002] In highly automated filter rod production lines, the tray loading machine is a key piece of equipment ensuring production efficiency, product quality, and process continuity. Among them, the YJ36 filter rod tray loading machine, due to its structural stability, is widely used in filter rod tray loading operations. The YJ36 filter rod tray loading machine consists of several parts, including a base and housing N1, an empty tray platform N2, a full tray conveyor, a feeding device, a material hopper, a lifting mechanism N5, an electrical control unit N6, a full tray ejection unit, and a support unit N10. (See attached diagram.) Figure 1 The YJ36 filter rod loading machine's full-tray conveying process is as follows: After the lifting mechanism N5 lowers the full tray to the predetermined position, the full-tray ejection unit is activated, pushing the full-loaded filter rods from the clamp of the lifting mechanism N5 to the front support unit N10 at the front end of the full-tray conveyor belt N3. Then, driven by the motor of the front support roller, the full tray is released onto the full-tray conveyor belt and moves backward. At the end of the full-tray conveyor belt N3, with the assistance of the rear support unit N10, the full trays are conveyed one by one to the full-tray lifting position N9, and further transferred to the next production area by the full-tray elevator. See details... Figure 1 There is a stopper N8 upstream of the full-disc lifting position N9. After the first full disc passes through, the stopper N8 will rise to block the entry of subsequent full discs, thus ensuring that there is only one full disc at the full-disc lifting position N9. The full-disc lifting machine at the full-disc lifting position N9 is used to lift the full disc to the next area. The stopper N8 and the full-disc lifting machine work together to ensure that one disc of filter rods is lifted each time.

[0003] At the full-disc conveying position of the YJ36 filter rod loading machine, there is a stopper N8 and a full-disc elevator. The stopper N8 is used to isolate the filter rod discs that arrive later, ensuring that the full-disc elevator lifts only one disc at a time, thus ensuring the orderly conveying process. Under normal operating conditions, this conveying channel only allows a single full disc to pass smoothly. However, in actual production, a "disc reversal" fault can easily occur: when the full-disc elevator fails to move the full disc that has reached the designated position upward in time, multiple subsequent full discs will be intercepted by the stopper N8 and accumulate at the full-disc conveying position (when the full-disc elevator fails to move the full disc that has reached the designated position upward in time, multiple subsequent full discs may accumulate in the same area due to the action of the stopper N8). Once the lifting mechanism resumes normal operation, all the previously intercepted full discs will pass through the stopper N8 in sequence and continue forward—the first full disc arrives first and triggers the lifting action, while the next full disc, which should have been blocked by the timely lifting of the stopper N8, will be blocked. However, in actual operation, the stopper N8 may not activate in time. If the second full-disc is not stopped in time and the disc moves forward a short distance before the stopper N8 activates (i.e., rises upwards), the second full-disc, which is directly above it, will be pushed over by the rising stopper N8. This is the "disc reversal" problem. To put it more simply, normally, only when the first full-disc successfully passes through the stopper N8 position and enters the full-disc lifting position N9 will the stopper N8 rise to prevent subsequent full-discs from entering. If there is a full-disc at the stopper N8 position, the stopper N8 will lift the full-disc during its ascent, thus causing the "disc reversal" problem.

[0004] The occurrence of tray tipping failure not only severely impacts production efficiency and causes production interruptions, but also results in filter rod material loss. Furthermore, the tipped-over filter rod trays may clog the conveying channel, further amplifying the impact of the failure and increasing equipment maintenance costs and manual cleaning workload. Currently, there are no effective countermeasures or solutions for this tray tipping problem in the YJ36 filter rod loading machine, failing to meet the high-efficiency, stable, and low-loss production requirements of automated production lines. Therefore, a technical solution that can fundamentally prevent tray tipping failure is urgently needed.

[0005] To address the above problems, this invention is proposed. Summary of the Invention

[0006] To address the issue of tray tipping in tray loading machines, this invention proposes an innovative solution: the YJ36 tray loading machine anti-tilting device. The core of this device lies in its detection and horizontal pushing unit 2, which detects and removes filter rod trays at the blocker N8. This design effectively prevents tray tipping, reduces material loss, and ensures unobstructed transport channels.

[0007] This invention provides an anti-tipping device for a YJ36 filter rod loading machine, belonging to the field of cigarette production machinery technology. The anti-tipping device includes a photoelectric detection unit 1, a horizontal pushing unit 2, a lifting platform 3, and an anti-tipping device bracket 4. The anti-tipping device is installed at the location of the stopper N8 on the YJ36 filter rod loading machine. This invention solves the problem of tipping failure in the YJ36 filter rod loading machine at its root. By using the photoelectric detection unit 1 to monitor the fullness status of the full tray in real time, combined with the coordinated action of the horizontal pushing unit 2 and the lifting platform 3, it can promptly transfer excess full trays in scenarios that easily lead to tipping, such as full tray accumulation and delayed action of the stopper N8, preventing the filter rod trays from being pushed over by the raised stopper N8, and completely eliminating the impact of tipping failure on production.

[0008] The first aspect of the present invention provides an anti-tipping device for a YJ36 filter rod loading machine, the anti-tipping device comprising a photoelectric detection unit 1, a horizontal pushing unit 2, a lifting platform 3, and an anti-tipping device bracket 4;

[0009] The horizontal push unit 2 includes a horizontal push drive motor 21, a horizontal push transmission mechanism 22, a horizontal slide 23, a horizontal guide rail 24, and a push plate 25. The horizontal push drive motor 21 serves as a power source. The horizontal push transmission mechanism 22 is used to convert the rotational motion output by the horizontal push drive motor 21 into the linear reciprocating motion of the horizontal slide 23 along the horizontal guide rail 24. The horizontal slide 23 is rigidly connected to the push plate 25. The horizontal slide 23 drives the push plate 25 to synchronously perform a linear pushing action in order to realize the horizontal push transfer of the filter rod disc.

[0010] The lifting platform 3 includes a lifting drive motor 31, a lifting transmission mechanism 32, a vertical slide 33, a vertical guide rail 34, and a lifting platform 35. The lifting drive motor 31 serves as a power output unit. The lifting transmission mechanism 32 is used to convert the rotational motion output by the lifting drive motor 31 into the linear lifting motion of the vertical slide 33 along the vertical guide rail 34. The vertical slide 33 is rigidly connected to the lifting platform 35 and completes the lifting action synchronously with the vertical displacement of the vertical slide 33, so as to receive the filter rod disc pushed by the horizontal push unit 2 and unload it to the ground.

[0011] Both the horizontal pushing unit 2 and the lifting platform 3 are fixed to the anti-tipping device bracket 4.

[0012] Preferably, the transverse push transmission mechanism 22 adopts any one of gear and rack transmission, screw and nut transmission or belt transmission to ensure the smoothness of the movement and displacement accuracy of the transverse slide table 23.

[0013] Preferably, the lifting transmission mechanism 32 adopts a screw and nut drive or a worm gear drive, which can realize the smooth lifting and locking of the lifting platform 35.

[0014] Preferably, the YJ36 filter rod loading machine includes a base and cover N1, an empty tray platform N2, a full tray conveyor belt N3, a filter rod feeding unit N4, a lifting mechanism N5, an electrical control unit N6, a loading unit N7, a stopper N8, a full tray ejection unit, a support unit N10, and a full tray elevator.

[0015] The filter rod feeding unit N4 is connected to the material storage and the tray loading unit N7 respectively, and is used to transport the filter rods in the material storage to the tray loading unit N7.

[0016] The empty tray platform N2 is connected to the tray loading unit N7 and is used to transport the air filter rod tray to the tray loading unit N7.

[0017] The tray loading unit N7 is used to receive the filter rods conveyed by the filter rod feeding unit N4 and load the filter rods into the empty filter rod tray conveyed by the empty tray platform N2;

[0018] The lifting mechanism N5 is correspondingly provided with the loading unit N7 and is used to lower the full tray N11 filled with filter rods in the loading unit N7 to a predetermined position.

[0019] The full-disc ejection unit is configured in correspondence with the lifting mechanism N5 and the support unit N10, and is used to push the full-disc held by the lifting mechanism N5 to the support unit N10.

[0020] The support unit N10 is equipped with a front support roller and a rear support roller. Under the motor drive of the front support roller, the full reel is released onto the full reel conveyor belt N3.

[0021] The full-disc conveyor belt N3 runs along the material conveying direction. The end of the full-disc conveyor belt N3 is the full-disc lifting position N9. The full-disc elevator is set at the full-disc lifting position N9 to receive the full disk at the full-disc lifting position N9 and transfer the full disk to the next production area. Under the motor drive of the rear support roller, the full disk is released from the full-disc conveyor belt N3 to the full-disc elevator.

[0022] The blocker N8 is located upstream of the full-disc lifting position N9. The blocker N8 can be embedded in or ejected from the full-disc conveyor belt N3. When the blocker N8 is embedded in the full-disc conveyor belt N3, the full disk can pass smoothly through the blocker N8 and reach the full-disc lifting position N9. When the blocker N8 is ejected from the full-disc conveyor belt N3, the full disk cannot pass smoothly through the blocker N8 and is stuck upstream of the blocker N8. Under normal circumstances, only the first full disk can pass smoothly through the blocker N8 position and enter the full-disc lifting position N9. After the first full disk passes, the blocker N8 will rise to block the subsequent full disks from entering. If there is a full disk at the blocker N8 position, the blocker N8 will tilt the full disk during the rising process, resulting in a tilting problem. The present invention is to design an anti-tipping device that can monitor in real time whether the blocker N8 is full. If not, the blocker N8 is raised normally; if it is, the anti-tipping device first clears the full plate from the blocker N8 before raising the blocker N8.

[0023] The electrical control unit N6 is electrically connected to the anti-tipping device, empty tray platform N2, full tray conveyor belt N3, filter rod feeding unit N4, lifting mechanism N5, tray loading unit N7, stopper N8, full tray ejection unit, support unit N10, and full tray elevator, respectively, and is used to control the coordinated operation of each component. The full tray lifting unit and full tray elevator are not shown in the figure.

[0024] The anti-tipping device is installed at the location of the blocker N8 on the YJ36 filter rod loading machine.

[0025] Preferably, the rotation direction of the front support roller and the rear support roller is consistent with the conveying direction of the full-disc conveyor belt N3, and the rotation speed of the front support roller is matched with the conveying speed of the full-disc conveyor belt N3 to ensure that the full disc is smoothly released onto the full-disc conveyor belt N3; the rotation speed of the rear support roller is matched with the conveying speed of the full-disc conveyor belt N3 to ensure that the full disc is smoothly released from the full-disc conveyor belt N3 to the full-disc elevator.

[0026] Preferably, the full-disc ejection unit includes a push cylinder and a push plate, the push plate being connected to the piston rod of the push cylinder, and the push plate being pushed in the direction of the support unit N10.

[0027] Preferably, the photoelectric detection unit 1 is located on the support of the full conveyor belt N3 where the blocker N8 is located. The photoelectric detection unit 1 adopts a photoelectric sensor. The photoelectric sensor detects vertically upward and monitors in real time whether the blocker N8 is full and whether there is accumulation. It can transmit the detected blocking signal to the electronic control unit N6 in real time.

[0028] The position of the photoelectric detection unit 1 can be selected according to the actual situation, as long as it can detect the location of the blocker N8.

[0029] Preferably, the electronic control unit N6 can receive the detection signal from the photoelectric detection unit 1. When the full-disc elevator is in operation and the photoelectric detection unit 1 detects an obstruction at the blocker N8 at the full-disc conveying position, the electronic control unit N6 controls the full-disc elevator to stop immediately and triggers an alarm signal. At the same time, it controls the lifting platform 3 to rise to a preset position and then controls the horizontal pushing unit 2 to start, pushing the filter rod disc at the blocker N8 horizontally to the lifting platform 3. After the filter rod disc is unloaded to the ground, the electronic control unit N6 controls the lifting platform 3 to reset and the full-disc elevator to resume normal operation.

[0030] Preferably, the alarm signal includes an audible and visual alarm, which facilitates staff to promptly detect and handle abnormal situations.

[0031] A second aspect of the present invention provides a method for preventing the trays of a YJ36 filter rod loading machine from tipping over, using the anti-tilting device for the YJ36 filter rod loading machine as described in any one of claims 1-9, comprising the following steps:

[0032] S1, Start-up: The YJ36 filter rod loading machine enters the full tray conveying process. The filter rod tray fully loaded with filter rods moves backward along the full tray conveying channel until the full tray is conveyed to the correct position.

[0033] S2, Detect full tray status: Photoelectric detection unit 1 detects the blocker N8 area of ​​the full tray conveying channel to determine whether there is full tray accumulation;

[0034] S21, Normal procedure without accumulation:

[0035] If the test result is "no full plate stacking", then the blocker N8 will be raised to block the subsequent full plates from being transported from the full plate conveying channel;

[0036] The full-disc hoist starts its lifting action, transferring the full-disc that has entered the full-disc lifting position N9 to the next area;

[0037] After the full-disc hoisting operation is completed, the stopper N8 descends and resets, waiting for the next full-disc to be in place;

[0038] S22, Anti-tipping procedure when there is stacking:

[0039] If the detection result is "full plate of accumulated material", the system will immediately trigger an alarm;

[0040] The lifting platform 3 rises to the preset receiving position;

[0041] The horizontal push unit 2 is activated, pushing the filter rod discs accumulated at the blocker N8 horizontally onto the lifting platform 3;

[0042] The lifting platform 3 is lowered to unload the filter rod disc onto the ground;

[0043] After the lifting platform 3 is reset, the blocker N8 is raised, blocking the subsequent full trays conveyed from the full tray conveying channel. The full tray elevator starts the lifting action, transferring the full trays that have entered the full tray lifting position N9 to the next area, and the equipment resumes normal conveying process.

[0044] S3, Cyclic Execution: Repeat the above steps to continuously monitor and control the full-disk conveying status, ensuring continuous operation of the production line.

[0045] The YJ36 filter rod loading machine consists of a base and cover N1, an empty tray platform N2, a full tray conveyor belt N3, a filter rod feeding unit N4, a lifting mechanism N5, an electrical control unit N6, a loading unit N7, a stopper N8, a full tray ejection unit, a support unit N10, and a full tray elevator. All components work together to complete the filter rod loading and full tray conveying. The specific process is as follows:

[0046] Step 1, Feeding and Empty Tray Supply: The filter rod feeding unit N4 is connected to the material storage and the tray loading unit N7 respectively, and stably transports the filter rods in the material storage to the tray loading unit N7; at the same time, the empty tray platform N2 is connected to the tray loading unit N7, and transports the empty filter rod tray to the designated position of the tray loading unit N7, preparing for the loading of filter rods.

[0047] Step 2, Filter rod loading: The loading unit N7 receives the filter rods delivered by the filter rod feeding unit N4 and loads them into the empty filter rod tray delivered by the empty tray platform N2 in an orderly manner until the filter rod tray is full, forming a full tray.

[0048] Step 3, full tray descent: The lifting mechanism N5 is set up in correspondence with the tray loading unit N7. After the tray loading unit N7 finishes loading the filter rods, the lifting mechanism N5 lowers the full tray in the tray loading unit N7 to the preset conveying position to facilitate the subsequent push-out operation.

[0049] Step 4, Full Disk Pushing and Support: The full disk ejection unit (composed of a push cylinder and a push plate, with the push plate connected to the cylinder piston rod and the push direction facing the support unit N10) is set up in correspondence with the lifting mechanism N5 and the support unit N10, pushing the full disk held by the lifting mechanism N5 to the support unit N10; the support unit N10 is equipped with a front support roller and a rear support roller. Under the motor drive of the front support roller (the rotation direction of the support roller is consistent with the conveying direction of the full disk conveyor belt N3, and the rotation speed of the front support roller matches the speed of the full disk conveyor belt N3), the full disk is smoothly released onto the full disk conveyor belt N3.

[0050] Step 5, Full Pan Conveying and Lifting: The full pan conveyor belt N3 runs along the material conveying direction, conveying the full pan to the end full pan lifting position N9; the full pan elevator is set at this lifting position to receive the conveyed full pan and transfer it to the next production area, completing the entire palletizing and conveying process. Driven by the motor of the rear support roller (the rotation speed of the rear support roller matches the conveying speed of the full pan conveyor belt N3 to ensure that the full pan is smoothly released from the full pan conveyor belt N3 to the full pan elevator), the full pan is released from the full pan conveyor belt N3 to the full pan elevator.

[0051] Step 6, Cyclic Operation: The above steps are continuously cycled, with the electrical control unit N6 controlling the coordinated work of each component to ensure continuous and stable operation of the production line.

[0052] The stopper N8 is located upstream of the full plate lifting position N9. Under normal operating conditions, only the first full plate is allowed to pass through the stopper N8 to enter the full plate lifting position N9. After the first full plate passes through, the stopper N8 rises to prevent subsequent full plates from entering, thus avoiding multiple full plates piling up at the lifting position. If there is already a full plate at the stopper N8, it will push the full plate over during the lifting process, causing a plate tipping problem. The anti-tipping device is designed to address this problem.

[0053] The anti-tipping mechanism of this invention works as follows:

[0054] The anti-tipping device is controlled by the electronic control unit N6 and operates in conjunction with the main process of the tray loading machine. Its core function is to monitor the position of the stopper N8 in real time through the photoelectric detection unit 1, triggering the anti-tipping action when the tray is fully stacked. The specific steps are as follows (explained in conjunction with the tray loading process):

[0055] Step 1, Preliminary preparation: Start the YJ36 filter rod loading machine, and the equipment enters normal operation. The anti-tipping device starts simultaneously, and the photoelectric detection unit 1 continuously detects the N8 area of ​​the blocker in real time. The electrical control unit N6 receives and analyzes the detection signal.

[0056] Step 2, normal loading and conveying (no risk of tray tipping):

[0057] When the full tray is conveyed along the full tray conveyor belt N3 to the stopper N8 position, if the photoelectric detection unit 1 detects "no full tray accumulation", it means that there is no full tray stuck at the stopper N8, which meets the normal operating conditions.

[0058] The electronic control unit N6 controls the stopper N8 to rise, blocking the subsequent delivery of full trays; at the same time, it starts the full tray elevator to transfer the full tray that has entered the full tray lifting position N9 to the next area.

[0059] After the full-disc elevator completes the lifting action, the electrical control unit N6 controls the stopper N8 to descend and reset, waiting for the next full-disc to be delivered to the position, and repeating the normal tray loading and conveying process.

[0060] Step 3, trigger anti-reverse action (risk of reversal):

[0061] When the full-disc hoist is in operation and the photoelectric detection unit 1 detects an obstruction (i.e., full-disc accumulation) at the position of the stopper N8, it indicates that there is full-disc residue at the stopper N8. If the stopper N8 is raised at this time, it will cause the disc to reverse. The electronic control unit N6 immediately triggers the following action:

[0062] The control system immediately stops the full-plate hoist and triggers an audible and visual alarm to alert staff to the abnormal situation.

[0063] The lifting platform 3 is started, and the lifting drive motor 31 drives the vertical slide 33 to rise along the vertical guide rail 34 through the lifting transmission mechanism 32 until the lifting platform 35 reaches the preset receiving position (matching the full plate height at the stop N8).

[0064] When the control unit 2 is started, the horizontal push drive motor 21 drives the horizontal slide table 23 to move along the horizontal guide rail 24 through the horizontal push transmission mechanism 22, which in turn drives the push plate 25 to smoothly push the filter rod disc accumulated at the blocker N8 onto the lifting platform 35 of the lifting platform 3.

[0065] The lifting platform 3 is controlled to descend, and the lifting drive motor 31 runs in reverse, driving the lifting platform 35 to descend to the ground, unloading the filter rod disc to the ground, and completing the full disc cleaning.

[0066] Step 4, Equipment Reset and Resumption of Operation: After the filter rod tray is unloaded to the ground, the electrical control unit N6 controls the lifting platform 3 to reset (the lifting platform 35 rises to the initial position), then controls the stopper N8 to rise, blocking subsequent full trays, and at the same time controls the full tray elevator to resume normal operation, continuing to transfer the full tray at the full tray lifting position N9, and the equipment returns to the normal tray loading and conveying process.

[0067] Step 5, Cyclic Monitoring: The photoelectric detection unit 1 continuously monitors the position status of the stopper N8, repeats the above normal process or anti-reverse process, and continuously detects and controls the full-disc conveying status to avoid reversal problems and ensure the continuous and stable operation of the production line.

[0068] In the YJ36 filter rod loading machine of this invention, the electrical control unit N6 is the core control hub for the entire loading and anti-tipping process. It is electrically connected to the anti-tipping device, empty tray platform N2, full tray conveyor belt N3, filter rod feeding unit N4, lifting mechanism N5, loading unit N7, stopper N8, full tray ejection unit, support unit N10, and full tray elevator. It achieves the following: controlling the various components of the loading machine to complete the filter rod loading, full tray conveying, and lifting in sequence; receiving the detection signal from the photoelectric detection unit 1 to determine whether there is a risk of tray tipping; triggering the anti-tipping action and alarm signal, controlling the linkage operation of various related components (full tray elevator, lifting platform 3, and horizontal push unit 2), and resetting the equipment after eliminating the risk of tray tipping; ensuring the continuous and safe operation of the equipment throughout the process, and avoiding the impact of tray tipping on production efficiency.

[0069] Compared with the prior art, the present invention has the following beneficial effects:

[0070] 1. This invention provides an anti-tipping device for the YJ36 filter rod loading machine, fundamentally solving the problem of tray tipping failure. Through a photoelectric detection unit 1, the full-load status of the tray is monitored in real time at the full-load conveying position. Combined with the coordinated action of the horizontal pushing unit 2 and the lifting platform 3, it can promptly transfer excess full trays in scenarios prone to tipping, such as tray accumulation and delayed action of the stopper N8, preventing the filter rod trays from being pushed over by the lifted stopper N8 and completely eliminating the impact of tipping failure on production. This invention introduces high-precision, fast-response sensing elements to detect the filter rod trays at the stopper N8, and automatically removes abnormal filter rod trays using the cooperation of the horizontal pushing unit 2 and the lifting platform 3. After installation, the frequency of tipping failure in the YJ36 filter rod loading machine has decreased from an average of twice a day to zero times a day, eliminating the tipping problem altogether.

[0071] 2. The anti-tipping device for the YJ36 filter rod loading machine of this invention effectively improves production efficiency and reduces production interruption time. This device can automatically complete the entire process of detection, alarm, horizontal pushing, unloading, and equipment reset without manual intervention. It avoids the tedious procedures of manually cleaning blocked channels and sorting materials after tray tipping, ensuring the continuous and stable operation of the filter rod loading production line and significantly improving overall production efficiency. This invention prevents clogging of the loading channel in the YJ36 filter rod loading machine, ensuring normal production.

[0072] 3. The anti-tipping device of the YJ36 filter rod loading machine of this invention reduces material loss and production costs. Tipping failure can easily lead to filter rods scattering and damage, resulting in material waste. This device reduces the loss of filter rod material by preventing tipping. At the same time, it reduces the costs of equipment failure maintenance and manual cleaning caused by tipping, further reducing the company's production and operation costs.

[0073] 4. The anti-tipping device for the YJ36 filter rod loading machine of this invention has a reasonable structural design and strong adaptability. This device is integrated into the existing full-tray conveying position of the YJ36 filter rod loading machine, without the need for large-scale modification of the main structure of the loading machine. It is easy to install, has low modification cost, and can perfectly adapt to the existing YJ36 filter rod loading machine's workflow and structural dimensions, facilitating mass promotion and application. It has a simple structure and is stable and reliable.

[0074] 5. The anti-tipping device of the YJ36 filter rod loading machine of the present invention is stable and reliable in operation and convenient in operation. The device is driven by a motor, which ensures smooth transmission and precise action. The photoelectric detection unit 1 has high detection sensitivity and can effectively avoid missed detection and false detection. At the same time, the electrical control unit N6 realizes full-process automated control. The staff only needs to pay attention to the abnormal situation when the alarm is triggered, which reduces the intensity of manual operation and improves the reliability and convenience of equipment operation.

[0075] 6. The anti-tipping device of the YJ36 filter rod loading machine of the present invention has an abnormal alarm function, which can promptly remind the staff to deal with equipment abnormalities. The audible and visual alarm signals are clear and unambiguous, making it easy for the staff to quickly locate the abnormal location, troubleshoot problems such as full-tray elevator failure, prevent the abnormal situation from escalating, and further ensure the stable operation of the production line.

[0095] like Figure 1-9 As shown, this embodiment provides an anti-tipping device for a YJ36 filter rod loading machine. The anti-tipping device includes a photoelectric detection unit 1, a horizontal pushing unit 2, a lifting platform 3, and an anti-tipping device bracket 4.

[0096] The horizontal push unit 2 includes a horizontal push drive motor 21, a horizontal push transmission mechanism 22, a horizontal slide 23, a horizontal guide rail 24, and a push plate 25. The horizontal push drive motor 21 serves as a power source. The horizontal push transmission mechanism 22 is used to convert the rotational motion output by the horizontal push drive motor 21 into the linear reciprocating motion of the horizontal slide 23 along the horizontal guide rail 24. The horizontal slide 23 is rigidly connected to the push plate 25. The horizontal slide 23 drives the push plate 25 to synchronously perform a linear pushing action in order to realize the horizontal push transfer of the filter rod disc.

[0097] The lifting platform 3 includes a lifting drive motor 31, a lifting transmission mechanism 32, a vertical slide 33, a vertical guide rail 34, and a lifting platform 35. The lifting drive motor 31 serves as a power output unit. The lifting transmission mechanism 32 is used to convert the rotational motion output by the lifting drive motor 31 into the linear lifting motion of the vertical slide 33 along the vertical guide rail 34. The vertical slide 33 is rigidly connected to the lifting platform 35 and completes the lifting action synchronously with the vertical displacement of the vertical slide 33, so as to receive the filter rod disc pushed by the horizontal push unit 2 and unload it to the ground.

[0098] Both the horizontal pushing unit 2 and the lifting platform 3 are fixed to the anti-tipping device bracket 4.

[0099] Preferably, the transverse push transmission mechanism 22 adopts any one of gear and rack transmission, screw and nut transmission or belt transmission to ensure the smoothness of the movement and displacement accuracy of the transverse slide table 23.

[0100] Preferably, the lifting transmission mechanism 32 adopts a screw and nut drive or a worm gear drive, which can realize the smooth lifting and locking of the lifting platform 35.

[0101] Preferably, the YJ36 filter rod loading machine includes a base and cover N1, an empty tray platform N2, a full tray conveyor belt N3, a filter rod feeding unit N4, a lifting mechanism N5, an electrical control unit N6, a loading unit N7, a stopper N8, a full tray ejection unit, a support unit N10, and a full tray elevator.

[0102] The filter rod feeding unit N4 is connected to the material storage and the tray loading unit N7 respectively, and is used to transport the filter rods in the material storage to the tray loading unit N7.

[0103] The empty tray platform N2 is connected to the tray loading unit N7 and is used to transport the air filter rod tray to the tray loading unit N7.

[0104] The tray loading unit N7 is used to receive the filter rods conveyed by the filter rod feeding unit N4 and load the filter rods into the empty filter rod tray conveyed by the empty tray platform N2;

[0105] The lifting mechanism N5 is correspondingly provided with the loading unit N7 and is used to lower the full tray N11 filled with filter rods in the loading unit N7 to a predetermined position.

[0106] The full-disc ejection unit is configured in correspondence with the lifting mechanism N5 and the support unit N10, and is used to push the full-disc held by the lifting mechanism N5 to the support unit N10.

[0107] The support unit N10 is equipped with a front support roller and a rear support roller. Under the motor drive of the front support roller, the full reel is released onto the full reel conveyor belt N3.

[0108] The full-disc conveyor belt N3 runs along the material conveying direction. The end of the full-disc conveyor belt N3 is the full-disc lifting position N9. The full-disc elevator is set at the full-disc lifting position N9 to receive the full disk at the full-disc lifting position N9 and transfer the full disk to the next production area. Under the motor drive of the rear support roller, the full disk is released from the full-disc conveyor belt N3 to the full-disc elevator.

[0109] The blocker N8 is located upstream of the full-disc lifting position N9. The blocker N8 can be embedded in or ejected from the full-disc conveyor belt N3. When the blocker N8 is embedded in the full-disc conveyor belt N3, the full disk can pass smoothly through the blocker N8 and reach the full-disc lifting position N9. When the blocker N8 is ejected from the full-disc conveyor belt N3, the full disk cannot pass smoothly through the blocker N8 and is stuck upstream of the blocker N8. Under normal circumstances, only the first full disk can pass smoothly through the blocker N8 position and enter the full-disc lifting position N9. After the first full disk passes, the blocker N8 will rise to block the subsequent full disks from entering. If there is a full disk at the blocker N8 position, the blocker N8 will tilt the full disk during the rising process, resulting in a tilting problem. The present invention is to design an anti-tipping device that can monitor in real time whether the blocker N8 is full. If not, the blocker N8 is raised normally; if it is, the anti-tipping device first clears the full plate from the blocker N8 before raising the blocker N8.

[0110] The electrical control unit N6 is electrically connected to the anti-tipping device, empty tray platform N2, full tray conveyor belt N3, filter rod feeding unit N4, lifting mechanism N5, tray loading unit N7, stopper N8, full tray ejection unit, support unit N10, and full tray elevator, respectively, and is used to control the coordinated operation of each component. The full tray lifting unit and full tray elevator are not shown in the figure.

[0111] The anti-tipping device is installed at the location of the blocker N8 on the YJ36 filter rod loading machine.

[0112] Preferably, the rotation direction of the front support roller and the rear support roller is consistent with the conveying direction of the full-disc conveyor belt N3, and the rotation speed of the front support roller is matched with the conveying speed of the full-disc conveyor belt N3 to ensure that the full disc is smoothly released onto the full-disc conveyor belt N3; the rotation speed of the rear support roller is matched with the conveying speed of the full-disc conveyor belt N3 to ensure that the full disc is smoothly released from the full-disc conveyor belt N3 to the full-disc elevator.

[0113] Preferably, the full-disc ejection unit includes a push cylinder and a push plate, the push plate being connected to the piston rod of the push cylinder, and the push plate being pushed in the direction of the support unit N10.

[0114] Preferably,

[0115] The photoelectric detection unit 1 is located on the support of the full conveyor belt N3 where the blocker N8 is located. The photoelectric detection unit 1 adopts a photoelectric sensor. The photoelectric sensor detects vertically upward and monitors in real time whether the blocker N8 is full and whether there is accumulation. It can transmit the detected blocking signal to the electronic control unit N6 in real time.

[0116] The position of the photoelectric detection unit 1 can be selected according to the actual situation, as long as it can detect the location of the blocker N8. The position of the photoelectric detection unit 1 shown in the figure is for illustrative purposes only.

[0117] Preferably, the electronic control unit N6 can receive the detection signal from the photoelectric detection unit 1. When the full-disc elevator is in operation and the photoelectric detection unit 1 detects an obstruction at the blocker N8 at the full-disc conveying position, the electronic control unit N6 controls the full-disc elevator to stop immediately and triggers an alarm signal. At the same time, it controls the lifting platform 3 to rise to a preset position and then controls the horizontal pushing unit 2 to start, pushing the filter rod disc at the blocker N8 horizontally to the lifting platform 3. After the filter rod disc is unloaded to the ground, the electronic control unit N6 controls the lifting platform 3 to reset and the full-disc elevator to resume normal operation.

[0118] Preferably, the alarm signal includes an audible and visual alarm, which facilitates staff to promptly detect and handle abnormal situations.

[0119] A second aspect of the present invention provides a method for preventing the trays of a YJ36 filter rod loading machine from tipping over, using the anti-tilting device for the YJ36 filter rod loading machine as described in any one of claims 1-9, comprising the following steps:

[0120] S1, Start-up: The YJ36 filter rod loading machine enters the full tray conveying process. The filter rod tray fully loaded with filter rods moves backward along the full tray conveying channel until the full tray is conveyed to the correct position.

[0121] S2, Detect full tray status: Photoelectric detection unit 1 detects the blocker N8 area of ​​the full tray conveying channel to determine whether there is full tray accumulation;

[0122] S21, Normal procedure without accumulation:

[0123] If the test result is "no full plate stacking", then the blocker N8 will be raised to block the subsequent full plates from being transported from the full plate conveying channel;

[0124] The full-disc hoist starts its lifting action, transferring the full-disc that has entered the full-disc lifting position N9 to the next area;

[0125] After the full-disc hoisting operation is completed, the stopper N8 descends and resets, waiting for the next full-disc to be in place;

[0126] S22, Anti-tipping procedure when there is stacking:

[0127] If the detection result is "full plate of accumulated material", the system will immediately trigger an alarm;

[0128] The lifting platform 3 rises to the preset receiving position;

[0129] The horizontal push unit 2 is activated, pushing the filter rod discs accumulated at the blocker N8 horizontally onto the lifting platform 3;

[0130] The lifting platform 3 is lowered to unload the filter rod disc onto the ground;

[0131] After the lifting platform 3 is reset, the blocker N8 is raised, blocking the subsequent full trays conveyed from the full tray conveying channel. The full tray elevator starts the lifting action, transferring the full trays that have entered the full tray lifting position N9 to the next area, and the equipment resumes normal conveying process.

[0132] S3, Cyclic Execution: Repeat the above steps to continuously monitor and control the full-disk conveying status, ensuring continuous operation of the production line.

[0133] The YJ36 filter rod loading machine consists of a base and cover N1, an empty tray platform N2, a full tray conveyor belt N3, a filter rod feeding unit N4, a lifting mechanism N5, an electrical control unit N6, a loading unit N7, a stopper N8, a full tray ejection unit, a support unit N10, and a full tray elevator. All components work together to complete the filter rod loading and full tray conveying. The specific process is as follows:

[0134] Step 1, Feeding and Empty Tray Supply: The filter rod feeding unit N4 is connected to the material storage and the tray loading unit N7 respectively, and stably transports the filter rods in the material storage to the tray loading unit N7; at the same time, the empty tray platform N2 is connected to the tray loading unit N7, and transports the empty filter rod tray to the designated position of the tray loading unit N7, preparing for the loading of filter rods.

[0135] Step 2, Filter rod loading: The loading unit N7 receives the filter rods delivered by the filter rod feeding unit N4 and loads them into the empty filter rod tray delivered by the empty tray platform N2 in an orderly manner until the filter rod tray is full, forming a full tray.

[0136] Step 3, full tray descent: The lifting mechanism N5 is set up in correspondence with the tray loading unit N7. After the tray loading unit N7 finishes loading the filter rods, the lifting mechanism N5 lowers the full tray in the tray loading unit N7 to the preset conveying position to facilitate the subsequent push-out operation.

[0137] Step 4, Full Disk Pushing and Support: The full disk ejection unit (composed of a push cylinder and a push plate, with the push plate connected to the cylinder piston rod and the push direction facing the support unit N10) is set up in correspondence with the lifting mechanism N5 and the support unit N10, pushing the full disk held by the lifting mechanism N5 to the support unit N10; the support unit N10 is equipped with a front support roller and a rear support roller. Under the motor drive of the front support roller (the rotation direction of the support roller is consistent with the conveying direction of the full disk conveyor belt N3, and the rotation speed of the front support roller matches the speed of the full disk conveyor belt N3), the full disk is smoothly released onto the full disk conveyor belt N3.

[0138] Step 5, Full Pan Conveying and Lifting: The full pan conveyor belt N3 runs along the material conveying direction, conveying the full pan to the end full pan lifting position N9; the full pan elevator is set at this lifting position to receive the conveyed full pan and transfer it to the next production area, completing the entire palletizing and conveying process. Driven by the motor of the rear support roller (the rotation speed of the rear support roller matches the conveying speed of the full pan conveyor belt N3 to ensure that the full pan is smoothly released from the full pan conveyor belt N3 to the full pan elevator), the full pan is released from the full pan conveyor belt N3 to the full pan elevator.

[0139] Step 6, Cyclic Operation: The above steps are continuously cycled, with the electrical control unit N6 controlling the coordinated work of each component to ensure continuous and stable operation of the production line.

[0140] The stopper N8 is located upstream of the full plate lifting position N9. Under normal operating conditions, only the first full plate is allowed to pass through the stopper N8 to enter the full plate lifting position N9. After the first full plate passes through, the stopper N8 rises to prevent subsequent full plates from entering, thus avoiding multiple full plates piling up at the lifting position. If there is already a full plate at the stopper N8, it will push the full plate over during the lifting process, causing a plate tipping problem. The anti-tipping device is designed to address this problem.

[0141] The anti-tipping mechanism of this invention works as follows:

[0142] The anti-tipping device is controlled by the electronic control unit N6 and operates in conjunction with the main process of the tray loading machine. Its core function is to monitor the position of the stopper N8 in real time through the photoelectric detection unit 1, triggering the anti-tipping action when the tray is fully stacked. The specific steps are as follows (explained in conjunction with the tray loading process):

[0143] Step 1, Preliminary preparation: Start the YJ36 filter rod loading machine, and the equipment enters normal operation. The anti-tipping device starts simultaneously, and the photoelectric detection unit 1 continuously detects the N8 area of ​​the blocker in real time. The electrical control unit N6 receives and analyzes the detection signal.

[0144] Step 2, normal loading and conveying (no risk of tray tipping):

[0145] When the full tray is conveyed along the full tray conveyor belt N3 to the stopper N8 position, if the photoelectric detection unit 1 detects "no full tray accumulation", it means that there is no full tray stuck at the stopper N8, which meets the normal operating conditions.

[0146] The electronic control unit N6 controls the stopper N8 to rise, blocking the subsequent delivery of full trays; at the same time, it starts the full tray elevator to transfer the full tray that has entered the full tray lifting position N9 to the next area.

[0147] After the full-disc elevator completes the lifting action, the electrical control unit N6 controls the stopper N8 to descend and reset, waiting for the next full-disc to be delivered to the position, and repeating the normal tray loading and conveying process.

[0148] Step 3, trigger anti-reverse action (risk of reversal):

[0149] When the full-disc hoist is in operation and the photoelectric detection unit 1 detects an obstruction (i.e., full-disc accumulation) at the position of the stopper N8, it indicates that there is full-disc residue at the stopper N8. If the stopper N8 is raised at this time, it will cause the disc to reverse. The electronic control unit N6 immediately triggers the following action:

[0150] The control system immediately stops the full-plate hoist and triggers an audible and visual alarm to alert staff to the abnormal situation.

[0151] The lifting platform 3 is started, and the lifting drive motor 31 drives the vertical slide 33 to rise along the vertical guide rail 34 through the lifting transmission mechanism 32 until the lifting platform 35 reaches the preset receiving position (matching the full plate height at the stop N8).

[0152] When the control unit 2 is started, the horizontal push drive motor 21 drives the horizontal slide table 23 to move along the horizontal guide rail 24 through the horizontal push transmission mechanism 22, which in turn drives the push plate 25 to smoothly push the filter rod disc accumulated at the blocker N8 onto the lifting platform 35 of the lifting platform 3.

[0153] The lifting platform 3 is controlled to descend, and the lifting drive motor 31 runs in reverse, driving the lifting platform 35 to descend to the ground, unloading the filter rod disc to the ground, and completing the full disc cleaning.

[0154] Step 4, Equipment Reset and Resumption of Operation: After the filter rod tray is unloaded to the ground, the electrical control unit N6 controls the lifting platform 3 to reset (the lifting platform 35 rises to the initial position), then controls the stopper N8 to rise, blocking subsequent full trays, and at the same time controls the full tray elevator to resume normal operation, continuing to transfer the full tray at the full tray lifting position N9, and the equipment returns to the normal tray loading and conveying process.

[0155] Step 5, Cyclic Monitoring: The photoelectric detection unit 1 continuously monitors the position status of the stopper N8, repeats the above normal process or anti-reverse process, and continuously detects and controls the full-disc conveying status to avoid reversal problems and ensure the continuous and stable operation of the production line.

[0156] In the YJ36 filter rod loading machine of this invention, the electrical control unit N6 is the core control hub for the entire loading and anti-tipping process. It is electrically connected to the anti-tipping device, empty tray platform N2, full tray conveyor belt N3, filter rod feeding unit N4, lifting mechanism N5, loading unit N7, stopper N8, full tray ejection unit, support unit N10, and full tray elevator. It achieves the following: controlling the various components of the loading machine to complete the filter rod loading, full tray conveying, and lifting in sequence; receiving the detection signal from the photoelectric detection unit 1 to determine whether there is a risk of tray tipping; triggering the anti-tipping action and alarm signal, controlling the linkage operation of various related components (full tray elevator, lifting platform 3, and horizontal push unit 2), and resetting the equipment after eliminating the risk of tray tipping; ensuring the continuous and safe operation of the equipment throughout the process, and avoiding the impact of tray tipping on production efficiency.

[0157] Specifically, such as Figure 1-9 The full-disc conveying process is as follows: Filter rods requiring loading enter the loading unit N7 from the material silo via the filter rod feeding unit N4. Empty trays for loading filter rods enter the loading unit N7 via the empty tray platform N2. The loading unit N7 loads the filter rods into the empty trays. The lifting mechanism N5 lowers the full tray to a predetermined position. The full-disc ejection unit pushes the full-loaded tray onto the support unit N10 at the front end of the full-disc conveyor belt N3. Subsequently, driven by the front support rollers, the full tray is released onto the full-disc conveyor belt N3 and travels downstream along the belt until it reaches the end. With the cooperation of the support unit N10, the full trays are sent one by one to the full-disc elevator, which then transfers the full trays to the next production area. Figure 1 and Figure 3 The full-disc lifting unit and the full-disc lifting machine are not shown in the drawing.

[0158] In this embodiment, an anti-tipping device is integrated at the N8 position of the stopper. Figure 2 The anti-tipping device includes a photoelectric detection unit 1, a horizontal pushing unit 2, a lifting platform 3, and an anti-tipping device bracket 4. Figure 4-5 This system can monitor in real time whether a full tray passes through the area. When the full tray elevator is operating, once the photoelectric sensor detects an obstruction (i.e., a full tray), the system will immediately stop the elevator and issue an alarm signal. At the same time, the lifting platform 3 rises, triggering the filter rod tray horizontal pushing unit 2, which pushes the filter rod tray at the obstruction N8 to the side of the lifting platform 3. The lifting platform 3 then unloads the filter rod tray to the ground, and the full tray elevator resumes operation.

[0159] Lateral Push Unit 2 ( Figure 6-7 The driving principle of the slide is as follows: the motor is used as the power source. The rotational motion output by the motor is converted into linear reciprocating motion of the slide along the guide rail through the transmission mechanism. The slide is rigidly connected to the push plate 25. The slide moves synchronously with the linear displacement of the slide to drive the push plate 25 to perform the corresponding pushing action, thereby realizing the linear pushing function of the target load.

[0160] Lifting Platform 3 ( Figure 8 The driving principle of the device is as follows: the motor is used as the power output unit. The rotational motion output by the motor is converted into the linear lifting motion of the slide table along the vertical guide rail 34 through the internal transmission mechanism of the device. The lifting table 35 is rigidly connected to the slide table and completes the lifting action synchronously with the vertical displacement of the slide table, so as to realize the vertical position adjustment function of the load.

S2, Detect full tray status: The photoelectric detection unit (1) detects the blocker (N8) area of ​​the full tray conveying channel to determine whether there is full tray accumulation; S21, Normal procedure without accumulation: If the test result is "no full tray stacking", the blocker (N8) will be raised to block the subsequent full trays transported from the full tray conveyor channel; The full-disc hoist starts its lifting action, transferring the full-disc that has entered the full-disc lifting position (N9) to the next area; After the full-plate hoisting operation is completed, the stopper (N8) descends and resets, waiting for the next full-plate to be in place; S22, Anti-tipping procedure when there is stacking: If the detection result is "full plate stacking", the system will immediately trigger an alarm; The lifting platform (3) rises to the preset receiving position; The horizontal push unit (2) is activated, pushing the filter rod discs accumulated at the blocker (N8) horizontally onto the lifting platform (3); The lifting platform (3) is lowered to unload the filter rod disc to the ground; After the lifting platform (3) is reset, the stopper (N8) is raised, blocking the subsequent full pans transported from the full pan conveying channel. The full pan elevator starts the lifting action, transferring the full pans that have entered the full pan lifting position (N9) to the next area, and the equipment resumes normal conveying process. S3, Cyclic Execution: Repeat the above steps to continuously monitor and control the full-disk conveying status, ensuring continuous operation of the production line.
