Description

Technical Field

[0001] This invention belongs to the field of intelligent control of equipment in cigarette material factories, and specifically relates to an automatic paper splicing method for preventing vibration of the filter rod. Background Technology

[0002] In the cigarette filter rod production process, the continuous and stable feeding of the forming paper is a crucial step in ensuring the quality and efficiency of filter rod formation. The forming paper is continuously drawn from a giant paper roll, undergoes a series of guiding and stretching processes, and is finally precisely fed to the filter rod forming machine, providing the basic material for the outer coating of the filter rod. This process is akin to the meshing of gears in a precision instrument; any interruption or instability in any stage can have a cascading impact on subsequent production.

[0003] However, when a roll of formed paper is about to run out, the traditional production model faces a thorny problem: the machine must be stopped to replace it with a new roll. This is not just a simple pause in operation; it means that the rhythm of the entire production line is forcibly interrupted—the forming machine runs idle due to lack of material, and the subsequent cutting and assembly processes also come to a standstill, greatly slowing down the continuous operation of the production line and becoming a key bottleneck restricting the release of production efficiency.

[0004] To alleviate this problem, some equipment has attempted to introduce a paper storage box as a transitional buffer, hoping to maintain short-term continuous conveying by storing paper during the transition between old and new rolls. However, in actual paper splicing, this buffer is often insufficient to withstand the interference caused by mechanical operation and tension changes. Paper shaking, shifting, and even breakage are still common occurrences, seriously affecting the stability of the conveying process.

[0005] Delving into the root cause of paper vibration during splicing, the primary reason lies in the drastic change in tension. As the old paper roll nears exhaustion, the tension it provides gradually decreases with the reduction in roll diameter; conversely, the tension generated by the drive mechanism surges suddenly at the moment the new paper roll starts. This dramatic fluctuation in tension, alternating between loosening and tightening, is akin to subjecting the paper to repeated pulling forces—at best, it causes localized stretching and deformation; at worst, it leads to overall loosening and wrinkling, resulting in high-frequency, irregular vibrations along the conveyor path, like a ribbon swaying erratically without stable traction.

[0006] Secondly, insufficient stability of the paper transport path is also a significant contributing factor. The transport path of formed paper requires passing through multiple sets of guide rollers, support frames, and other components. If the positioning accuracy of these guide structures is insufficient, the surface smoothness is inadequate, or slight wear and misalignment occurs after long-term use, the paper will lose its stable "track" during transport. At the moment of paper contact, this pre-existing path deviation will be drastically amplified: the paper may shift to the left and rub against the left support, and a moment later, it may sway to the right and rub against the right roller. The repeated collisions and friction generate continuous vibration, further exacerbating the shaking amplitude.

[0007] More importantly, the lag in the manual paper-feeding process makes it difficult to control the shaking problem in a timely manner. Manual operation relies on the operator's visual observation, experience-based judgment, and manual adjustment of the paper's condition. However, there is a significant time lag between noticing the paper's looseness or tightness, making an adjustment, and the actual change in tension. This lag means that tension adjustment is always slower than the real-time changes in the paper's condition—by the time the operator notices the paper is stretched due to excessive tension, the adjusted tension may have already become excessively loose; when looseness is detected, adding more tension may cause further stretching. This cycle repeats, and the shaking not only fails to subside but also continues to be transmitted to subsequent cutting and forming processes, leading to quality problems such as deviations in cutting positions and uneven interfaces on the formed filter rods.

[0008] Although some improvements have been made in existing technologies, such as the static paper receiving mechanism and buffer area set in some cigarette filter rod forming paper conveying devices, the static mechanism can only function in a stable state. It cannot respond in real time to the dynamic tension fluctuations and path deviations at the moment of paper receiving, and it is difficult to form a systematic anti-vibration control logic. Other paper feeding mechanisms provide buffer space through the paper storage cavity, which can temporarily store some paper to cope with the roll changing gap. However, the paper storage cavity can only passively receive paper and cannot be linked with the dynamic tension adjustment during the paper receiving process. It cannot actively offset the impact caused by the sudden change in tension, so it is still difficult to fundamentally solve the vibration problem during paper receiving.

[0009] Furthermore, unlike the independent paper splicing systems in other industries, the formed paper in cigarette material plants needs to be rolled and packaged together with the tow. Multiple systems operate simultaneously and collaboratively, so it is necessary to do everything possible to avoid the cumulative risk fluctuations that fluctuations in the paper splicing process may bring to the entire filter rod production line. Summary of the Invention

[0010] The purpose of this invention is to automatically control the paper splicing of filter rods in cigarette material factories, thereby solving the paper vibration problem caused by sudden tension changes, path deviations, and insufficient buffering during the existing paper splicing process, achieving a smooth transition in the splicing process, and ensuring the quality of subsequent processing.

[0011] This invention provides an automatic paper splicing method for anti-vibration of paper using a paper feeder, used in an automatic paper splicing system for anti-vibration of paper using a paper feeder. The method is characterized by comprising a first paper roll mechanism, a second paper roll mechanism, and a splicing mechanism, and includes the following steps: Step A: Pre-splicing preparation; Step B: Dynamic tension adjustment; Step C: Path stabilization control; Step D: Buffer compensation.

[0012] Furthermore, in step A: the remaining amount of the first paper roll is monitored in real time by the first remaining amount detection component of the first paper roll mechanism. When the remaining amount is lower than the remaining amount threshold, the automatic paper splicing program is triggered and the paper splicing mechanism is started to operate.

[0013] Furthermore, the remaining amount threshold is preset to 1.9-2.1m, and the tension stability range of the first paper roll is preset to 10-15N.

[0014] Furthermore, the paper splicing mechanism includes a vision sensor, which is used to calibrate the tail position of the first paper roll and / or the head position of the second paper roll and control the error within ±0.5mm.

[0015] Furthermore, in step B: 0.95-1.05 seconds before paper is received, the controller reduces the traction force of the first paper roll from 14.0-16.0N to 0.48-0.52N, while the controller increases the traction force of the second paper roll to 0.48-0.52N; at the moment of paper reception, the controller simultaneously increases the traction force of the first paper roll and the traction force of the second paper roll to 9.8-10.5N.

[0016] Furthermore, in step B, the paper splicing mechanism includes a traction force detection component, and the traction force of the first paper roll and the traction force of the second paper roll are both controlled within the range of 95%-105% of the preset value.

[0017] Furthermore, in step B, the controller uses a PID control algorithm to adjust the traction force of the first paper roll and the second paper roll.

[0018] Furthermore, the paper receiving mechanism also includes guide wheels and / or guide plates to constrain the paper path to ensure that the paper is fed in a straight line.

[0019] Furthermore, the automatic paper splicing system for anti-shake paper feeding also includes an electrostatic elimination mechanism; in step C, the electrostatic elimination mechanism is activated to remove static electricity from the paper surface.

[0020] Furthermore, the automatic paper feeding system for the mouthpiece also includes a paper storage mechanism; in step A, the pre-storage threshold of the paper storage mechanism is preset to 0.98-1.05m; in step D, after the paper feeding is completed, it is replenished at a speed of 0.15-0.30m / s for 5-12 seconds.

[0021] The specific advantages of this invention are mainly reflected in the following aspects:

[0022] (I) Paper Reception Preparation Mechanism: The remaining amount of old paper rolls is monitored in real time through high-precision detection components, constructing an all-weather paper roll status perception system. When the remaining amount of old paper rolls reaches a preset threshold, the system automatically triggers the paper reception program, completing preliminary work such as new paper roll start-up preparation and pre-activation of relevant drive devices, laying the foundation for seamless connection.

[0023] (II) Dynamic Tension Coordination Adjustment System: To address the issue of sudden tension changes at the moment of paper splicing, a coordinated control strategy of traction force between the old and new paper rolls is adopted. When the paper splicing action is initiated, the traction force of the old paper roll is gradually reduced to a preset baseline value, while the traction force of the new paper roll is simultaneously increased. Through bidirectional dynamic adjustment, the tension difference between the two is controlled within a very small range, avoiding paper stretching or loosening caused by drastic tension fluctuations.

[0024] (iv) Introduction of a closed-loop tension feedback mechanism: The tension sensor captures changes in paper tension in real time and transmits the signal to the central controller immediately. The controller dynamically adjusts the rotation speed of the unwinding and take-up rollers of the new and old paper according to the preset control logic, ensuring that the paper maintains a stable tension state throughout the entire paper feeding process, thereby suppressing the vibration caused by tension fluctuations at the source.

[0025] (V) Conveying Path Stability Control System: A multi-dimensional path constraint structure is constructed, and a guiding system consisting of guide wheels and adjustable-width guide plates forms a rigid constraint on the paper conveying path. The guide wheels are installed with high-precision positioning to ensure smooth rotation without jamming; the width of the guide plate can be adaptively adjusted according to the paper specifications, so that the paper is always conveyed along the preset trajectory and avoids lateral deviation.

[0026] (vi) Add an electrostatic elimination and softening mechanism: remove the static electricity accumulated on the paper surface by physical means, eliminate the paper sticking caused by electrostatic adsorption, and at the same time reduce the irregular shaking of the paper caused by static electricity, thereby improving the stability of paper conveying.

[0027] (vii) Intelligent buffer compensation mechanism: A paper storage chamber is set up as a material buffer unit during the paper receiving process. The paper release amount is precisely controlled by dynamically adjusting the speed of the paper feed rollers. During paper receiving, the paper storage chamber releases the pre-stored paper to compensate for the instantaneous fluctuations in the conveying volume during the paper receiving process and maintain the continuity of the production line input.

[0028] In addition, after the paper is fed, the system automatically stops pulling the old paper roll and smoothly transitions the pulling force of the new paper roll to normal operating conditions. Simultaneously, the paper storage chamber initiates a replenishment program, adjusting the conveyor speed to restore the preset paper storage volume, preparing for the next paper feeding.

[0073] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0074] refer to Figure 1The present invention provides an automatic paper feeding system for anti-shake paper feeders, comprising: a first paper roll mechanism 100, a second paper roll mechanism 200, a paper feeding mechanism 300, an electrostatic elimination mechanism 500, and a paper storage mechanism 900, all of which are controlled by a control system. The first paper roll mechanism 100 includes a first remaining quantity detection component 110, and the second paper roll mechanism 200 includes a second remaining quantity detection component 210.

[0075] like Figure 2 As shown, the first paper roll mechanism 100 and the second paper roll mechanism 200 unwind and guide the formed paper to the receiving mechanism 300. The receiving mechanism 300 internally includes a pressing component 310 for pressing down the first formed paper and an lifting component 320 for lifting the second formed paper. When the first formed paper of the first paper roll mechanism 100 is being transported normally, the unwinding control component 370 in the receiving mechanism 300 provides tensioning and guiding for both the first formed paper of the first paper roll mechanism 100 and the second formed paper of the second paper roll mechanism 200. For example, the first formed paper is tensioned by the guide wheel 330 and the conveying wheel 340, and the second formed paper is attached to the tensioning wheel of the lifting component. The tension can be detected by a conventional traction force detection component 360. When the first formed paper is almost used up, the receiving mechanism 300 automatically applies adhesive tape to the tail end of the first formed paper (or the tail end can be cut off) and the first section of the second formed paper. This step can also be done manually. Subsequently, under the action of the paper receiving mechanism, the first and second forming papers are automatically bonded together to achieve end-to-end connection. That is, the upper top component 320 and the lower pressing component 310 can touch and press the tail end of the first forming paper and the first section of the second forming paper together to achieve automatic end-to-end bonding.

[0076] In addition, an electrostatic elimination mechanism 500 can be provided, which can remove static electricity from the paper surface and prevent paper sticking and irregular shaking caused by electrostatic adsorption.

[0077] After the formed paper leaves the paper receiving mechanism 400, it can be directly connected to the tow forming production line, or it can be further buffered by the paper storage mechanism 600.

[0078] like Figure 3 As shown, the paper storage mechanism 600 is defined by a paper storage box 691, which has a communicating paper storage cavity 610 and a paper feeding cavity 620. The paper storage cavity 610 has a paper inlet, and the paper feeding cavity 620 has a paper feeding outlet 650. The paper storage cavity 610 and the paper feeding cavity 620 are respectively connected to the paper inlet and the paper feeding outlet 5 on the paper storage box 691, and the paper storage cavity 610 is connected to the paper feeding cavity 620 so that the paper strips forming the paper roll enter the paper storage cavity 610 through the paper inlet, and then exit through the paper feeding cavity 620 and the paper feeding outlet 650.

[0079] The separating assembly includes a separating plate 692 and a smooth flexible member 671 disposed at the bottom of the separating plate 692. The separating plate 692 is connected to the inner surface of the top of the paper storage box 691. The smooth flexible member 671 has a smooth surface, which is used to reduce the friction between the smooth flexible member 671 and the paper strip and to prevent the paper strip from being pulled or worn off at the smooth flexible member 671. In order to prevent the paper strip from accumulating in the paper feeding cavity 620, the paper feeding cavity 620 is provided with several guide members, such as the first guide member 672, the second guide member 673, the third guide member 674, and the fourth guide member 675, which are evenly arranged along the paper strip feeding direction. The guide members can be specifically configured as limit rods and guide wheels, etc.

[0080] A paper feed roller 630, located at the paper inlet, is used to transport the paper strip of the formed paper roll into the paper storage cavity 610. A paper storage cavity level detection component is located within the paper storage cavity 610 to detect the remaining paper level. Specifically, it can be configured as a photoelectric sensor 660 or an ultrasonic sensor, etc. The bottom paper strip is positioned on the sensor's signal propagation path. When the sensor can receive the reflected signal transmitted by the reflective component 680 or the receiver located at the end of the signal propagation path can receive the incident signal, the sensor's signal propagation path is unobstructed by the paper strip, indicating that the paper level in the paper storage cavity 610 is below a threshold.

[0081] refer to Figure 4 The present invention provides an automatic paper-splitting method for preventing paper vibration in a mouthpiece, comprising:

[0082] Step A: Preparation before splicing paper

[0083] The remaining amount of old paper rolls is monitored in real time by a detection component (first remaining amount detection component 110 or second remaining amount detection component 210). When the remaining amount is lower than a preset threshold, an automatic paper splicing program is triggered, and the paper splicing mechanism 300 starts operating. Depending on the paper type (e.g., filter rod forming paper), the remaining amount threshold of the old paper roll, the tension stability range, and the pre-stored threshold of the paper storage mechanism can be preset. For filter rod forming paper, the inventors found through extensive testing that setting the remaining amount threshold of the old paper roll to 1.9-2.1m, the tension stability range to 10-15N, and the pre-stored threshold of the paper storage mechanism to 0.98-1.05m can ensure the long-term stability of the filter rod production line.

[0084] Then, the beginning of the new paper roll can be aligned with the end of the old paper roll manually or automatically. In automatic operation, the control module initiates the movement of the new paper roll unwinding device, and the vision sensor 380 calibrates the lead position, with the error controlled within ±0.5mm. The control module moves the new paper roll unwinding device to the receiving position, aligning the beginning of the new paper roll with the end of the old paper roll; the alignment accuracy is calibrated by the vision sensor.

[0085] Step B: Dynamic tension adjustment

[0086] The traction force detection component 360° continuously monitors the tension of the first and second forming sheets and adjusts the tension through the unwinding control component 370. At the moment of paper contact, the traction force of the old paper roll is reduced to a preset low value, while the traction force of the new paper roll is gradually increased, so that the tension difference is controlled within ±5%.

[0087] When the remaining amount of old paper rolls reaches or falls below the threshold, the buffer preparation of the paper storage chamber is activated to ensure that the amount of paper pre-stored in the paper storage chamber meets the production line requirements during paper receiving, and the remaining length of the paper storage chamber is greater than 1m.

[0088] Based on data from numerous experiments, it is necessary to reduce the traction force of the old paper roll from 14.0-16.0N to 0.48-0.52N and increase the traction force of the new paper roll from 0 to 0.48-0.52N 0.95-1.05 seconds before the paper is joined, with the difference between the two traction forces controlled within 0.02N. At the instant of the paper joining (within ±0.2 seconds of the initial and final joining), both traction forces should simultaneously increase to 9.8-10.5N to complete the transition. Specifically, 1.0 second before the paper is joined, the traction force of the old paper roll should be reduced from 15.0N to 5.0N, and the traction force of the new paper roll should be increased from 0 to 5N; at the instant of the paper joining (within 0.2 seconds of the initial and final joining), both traction forces should simultaneously increase to 10.0N to complete the transition.

[0089] During this process, the paper tension is monitored in real time using a traction force detection component, and the data is fed back to the controller. The controller maintains stable tension by adjusting the rotation speeds of the unwinding and rewinding rollers in the unwinding control component. The controller uses a PID control algorithm to adjust the traction force, keeping it within 95%-105% of the preset value to ensure stable tension.

[0090] Step C: Path stability control

[0091] During the paper feeding process, the paper path is constrained by the guide wheel 330 and / or the adjustable width guide plate (not shown in the figure) to ensure that the paper is fed in a straight line and avoid lateral deviation.

[0092] At the same time, the static elimination mechanism 500 is activated to remove static electricity from the paper surface and prevent paper sticking and irregular shaking caused by static adsorption.

[0093] Step D: Buffer Compensation

[0094] During paper feeding, the paper storage mechanism 600 releases pre-stored paper by adjusting the rotation speed of the feed rollers 630, compensating for instantaneous fluctuations in the conveyor flow caused by paper feeding and maintaining a constant input volume in the production line. After paper feeding is completed, the traction force of the old paper roll is reduced to zero, while the traction force of the new paper roll returns to its normal operating value. The paper storage mechanism 600 simultaneously replenishes paper to the preset storage level. If compensation is required during paper feeding according to system requirements, such as a normal system speed of 0.15 m / s, replenishment is carried out at a speed of 0.2 m / s for 10 seconds after paper feeding is completed.

[0095] Based on the same inventive concept, this application also provides a computer system including a memory, a processor, and computer-readable instructions stored in the memory and executable on the processor.
