Description

Technical Field

[0001] The present invention relates to the technical field of production packaging, and particularly to an adhesive tape cylinder fixing device and a profile adhesive tape packaging device. Background Art

[0002] In order to effectively protect aluminum profiles, a layer of adhesive tape is usually wrapped on the surface of aluminum profiles when they leave the factory to prevent scratches during transportation and the invasion of dust and moisture during storage. This packaging process is generally completed by a profile packaging machine. During the packaging process, the adhesive tape cylinder for packaging needs to be fixed on a fixing device. In the profile packaging machine, the adhesive tape cylinder rotates on the device to achieve automatic tape feeding.

[0003] As Figure 12 shown, existing fixing devices mostly use fixing gaskets to block both ends of the adhesive tape cylinder, thereby fixing the adhesive tape cylinder. When replacing the adhesive tape cylinder, the staff needs to remove the fixing gasket, remove the old adhesive tape cylinder, then install a new adhesive tape cylinder, and re-fix the gasket. This process is not only time-consuming but also requires fine adjustment of the gap between the adhesive tape cylinder and the fixing gasket to ensure the smooth rotation of the adhesive tape reel, and the overall operation is rather cumbersome.

Detailed implementation manners

[0033] Hereinafter, with reference to the accompanying drawings, the preferred implementation manners of the present application will be described in detail. In the following description, the same reference numerals are given to the same components, and repeated descriptions are omitted. In addition, the drawings are only schematic diagrams, and the proportional relationship of the dimensions between components or the shape of components, etc. may be different from the actual ones. It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0034] It should also be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0035] Referring to Figure 1 and Figure 2 , the present application provides an adhesive tape cylinder fixing device, which includes: a guiding shaft 1, one end of the guiding shaft 1 is used for being installed on an external profile adhesive tape packaging device; a rotating member 2, sleeved on the guiding shaft 1 and capable of rotating around the guiding shaft 1; a limiting assembly 3, connected to the guiding shaft 1, and the limiting assembly 3 is located at opposite ends of the rotating member 2; a tensioning assembly 4, connected to the rotating member 2, and the tensioning assembly 4 has elasticity, and the tensioning assembly 4 is used for pressing against the inner wall of the adhesive tape cylinder 100 under the action of an elastic restoring force.

[0036] According to the above structure, after the staff fixes the adhesive tape cylinder 100 on the adhesive tape cylinder fixing device, the elastic restoring force of the tensioning assembly 4 can press against the inner wall of the adhesive tape cylinder 100, so as to realize the fixing of the adhesive tape cylinder 100. When it is necessary to remove the adhesive tape cylinder 100, the adhesive tape cylinder 100 can be removed with a little external force. In this way, during the process of placing and removing the adhesive tape cylinder 100, there is no need to disassemble any additional components, and the whole operation process is convenient and fast. In addition, referring to Figure 12Compared with the traditional fixing device, it is necessary to seal the two ends of the adhesive tape tube 100 with the fixing gasket 8 to achieve fixing. In order to ensure that the adhesive tape tube 100 can rotate smoothly, it is also necessary to adjust the gap between the fixing gasket 8 and the adhesive tape tube 100. The adhesive tape tube fixing device provided by the present application omits the work of adjusting the gap between the adhesive tape tube 100 and the fixing gasket 8 by pressing the tensioning component 4 against the inner wall of the adhesive tape tube 100, which has lower requirements on the operating skills of the staff and is also conducive to improving the operating efficiency.

[0037] Specifically, refer to Figure 12 The adhesive tape cylinder 100 involved in the present application includes adhesive tape and a cylinder. The adhesive tape is wound around the outside of the cylinder. The cylinder is hollow and connected to the outside in the axial direction. When fixing the adhesive tape cylinder 100, the staff only needs to insert the adhesive tape cylinder 100 into the adhesive tape cylinder fixing device in the present application, and the elastic reset force of the tensioning assembly 4 can be against the inner wall of the cylinder. In addition, the setting of the limit assembly 3 at the opposite ends of the rotating member 2 can also be understood as the limit assembly 3 clamping the rotating member 2 to limit the movement of the rotating member 2 along the axial direction of the guide shaft 1. In order to ensure that the rotating member 2 can rotate, there is a gap between the limit assembly 3 and the rotating member 2.

[0038] Reference Figures 4 to 7 In some embodiments, the tensioning assembly 4 includes a pressing member 41 and a spring 42; the two ends of the spring 42 press against the pressing member 41 and the rotating member 2 respectively, and the side of the pressing member 41 facing away from the rotating member 2 is used to press against the inner wall of the adhesive tape tube 100. Therefore, the elastic restoring force of the spring 42 can push the pressing member 41 toward the outer periphery of the rotating member 2, and after the adhesive tape tube 100 is fixed to the adhesive tape tube fixing device, the pressing member 41 will press against the inner wall of the adhesive tape tube 100 under the action of the elastic restoring force of the spring 42.

[0039] When it is necessary to replace the adhesive tape cylinder 100, the staff removes the old adhesive tape cylinder 100 along the axial direction of the rotating member 2. Since the pressing member 41 realizes the pressing and fixing of the adhesive tape cylinder 100 by the elastic force of the spring 42, when removing the old adhesive tape cylinder 100, the staff only needs to apply a little external force and remove the adhesive tape cylinder 100 along the axial direction of the rotating member 2. When it is necessary to install a new adhesive tape cylinder 100, the staff sleeves the new adhesive tape cylinder 100 along the axial direction of the rotating member 2 on the adhesive tape cylinder fixing device. At this time, the adhesive tape cylinder 100 will compress the spring 42. At the same time, the elastic restoring force of the spring 42 presses the pressing member 41 against the inner wall of the adhesive tape cylinder 100 to complete the fixing of the adhesive tape cylinder 100. Specifically, the pressing member 41 presses against the adhesive tape cylinder 100, the adhesive tape cylinder 100 and the rotating member 2 remain stationary, and the rotating member 2 can rotate around the guiding shaft 1. During the process of packaging the profile with the adhesive tape cylinder 100, the adhesive tape on the adhesive tape cylinder 100 is pulled out. During the continuous feeding of the adhesive tape, the rotating member 2 continuously rotates around the guiding shaft 1.

[0040] Referring to Figure 8 , in some embodiments, in the axial direction of the guiding shaft 1, the adhesive tape cylinder fixing device includes a placement end. The pressing member 41 includes a guiding portion 411 and a pressing portion 412 that are connected to each other and are relatively positioned. The guiding portion 411 is close to the placement end; the guiding portion 411 is inclined relative to the pressing portion 412, and the guiding portion 411 is inclined toward the axial direction of the guiding shaft 1; the side of the pressing portion 412 facing away from the rotating member 2 is used to abut against the inner wall of the adhesive tape cylinder 100. Thus, on the one hand, the inclined guiding portion 411 can facilitate the placement of the adhesive tape cylinder 100, without the need for the staff to perform precise alignment, reducing the operation difficulty and improving the work efficiency. On the other hand, there may be slight inner diameter deviations in different batches of adhesive tape cylinders 100. The inclined guiding portion 411 can better adapt to the inner diameters of different adhesive tape cylinders 100, enabling the adhesive tape cylinder 100 with a slightly narrower inner diameter to be smoothly sleeved, ensuring the versatility and flexibility of the adhesive tape cylinder fixing device.

[0041] In some embodiments, the surface of the pressing portion 412 is provided with anti-slip lines. Since the surface of the pressing portion 412 abuts against the inner wall of the adhesive tape cylinder 100, the setting of the anti-slip lines can increase the friction between the pressing portion 412 and the inner wall of the adhesive tape cylinder 100. When the adhesive tape cylinder 100 rotates with the rotating member 2, this friction helps to prevent the cylinder from sliding or shifting on the adhesive tape cylinder fixing device.

[0042] In other embodiments, the surface of the pressing portion 412 may also be provided with an anti-slip rubber pad, so as to achieve the effect of increasing the friction between the pressing portion 412 and the inner wall of the adhesive tape cylinder 100.

[0043] Referring to Figure 10, in some embodiments, along the circumferential direction of the guiding shaft 1, a plurality of tensioning components 4 are evenly distributed on the surface of the rotating member 2. Thus, the plurality of evenly distributed tensioning components 4 act on the adhesive tape cylinder 100 together, thereby achieving a more stable and effective fixing effect, and also being able to avoid the vibration and displacement of the adhesive tape cylinder 100 caused by loosening. In addition, the distribution of the plurality of tensioning components 4 not only improves the uniformity and reliability of the pressing effect, but also reduces the deformation of the adhesive tape cylinder 100 that may be caused by excessive local pressure.

[0044] In some embodiments, the tensioning component 4 extends along the axial direction of the guiding shaft 1. Specifically, the extension length of the tensioning component 4 can be set according to the length of the adhesive tape cylinder 100 used.

[0045] In some embodiments, the limiting component 3 includes a first limiting disk 31 and a second limiting disk 32. The first limiting disk 31 and the second limiting disk 32 are respectively sleeved at both ends of the rotating member 2; the cross-section of the first limiting disk 31 is larger than the cross-section of the rotating member 2. Thus, in the circumferential direction of the rotating member 2, the first limiting disk 31 protrudes from the rotating member 2. Specifically, the second limiting disk 32 is close to the insertion end of the adhesive tape cylinder fixing device, and the outer diameter of the second limiting disk 32 is set to be smaller than the inner diameter of the adhesive tape cylinder 100, and the adhesive tape cylinder 100 will pass through the second limiting disk 32 when inserted. The staff continues to push the adhesive tape cylinder 100, then the adhesive tape cylinder 100 will abut against the first limiting disk 31, and the first limiting disk 31 can play a positioning role to ensure the correct position of the adhesive tape cylinder 100 on the rotating member 2 and avoid the situation that the adhesive tape cylinder 100 is not placed in place and falls during the packaging process.

[0046] Refer to Figure 7 , in some embodiments, the second limiting disk 32 includes a first limiting portion 321 and a second limiting portion 322 which are connected to each other; the first limiting portion 321 is connected to the end of the rotating member 2, and the second limiting portion 322 surrounds the circumferential side of the rotating member 2; the tensioning component 4 abuts against the side of the second limiting portion 322 facing the rotating member 2 under the action of the elastic restoring force. Specifically, the tensioning component 4 abuts against the side of the second limiting portion 322 facing the rotating member 2. Thus, the second limiting portion 322 can play a limiting role on the tensioning component 4 to prevent the elastic restoring force of the spring 42 from pushing the tensioning component 4 out and causing the tensioning component 4 to fall off.

[0047] Refer to Figure 5 , in some examples, the rotating member 2 is provided with a movable groove 21 for accommodating the pressing member 41, and the inner wall of the movable groove 21 fits with the outer wall of the pressing member 41. Thus, the movable groove 21 has a certain guiding effect on the pressing member 41. When the spring 42 pushes the pressing member 41, the pressing member 41 can move along the inner wall of the movable groove 21 to avoid the deviation of the pressing direction of the pressing member 41 under the action of the elastic restoring force of the spring 42.

[0048] In some examples, the rotating member 2 may further be provided with a receiving groove 22 for receiving the spring 42. The receiving groove 22 communicates with the moving groove 21. One end of the spring 42 can abut against the inner wall of the receiving groove 22, and the other end of the spring 42 can extend into the moving groove 21 to abut against the pressing member 41.

[0049] In some examples, the first limiting disc 31 may be threadedly connected to one end of the rotating member 2, and the second limiting disc 32 may be threadedly connected to the other end of the rotating member 2.

[0050] Referring to Figures 2 to 9 , in some embodiments, the limiting assembly 3 further includes two positioning members 33. The two positioning members 33 are provided on the guide shaft 1. A positioning member 33 is provided on the side of the first limiting disc 31 facing away from the rotating member 2, and a positioning member 33 is provided on the side of the second limiting disc 32 facing away from the rotating member 2; the adhesive tape cylinder fixing device further includes an adjusting assembly 5. The adjusting assembly 5 is provided on the guide shaft 1. The adjusting assembly 5 is movably connected to the two positioning members 33 to synchronously adjust the positions of the two positioning members 33 on the guide shaft 1. Specifically, in this embodiment, it can also be regarded that the two positioning members 33 are clamped at both ends of the rotating member 2 to limit the movement of the rotating member 2 along the axial direction of the guide shaft 1. It should be noted that in order to ensure that the adhesive tape cylinder 100 can rotate smoothly to feed the tape, a gap needs to be left between the first limiting disc 31 and the corresponding positioning member 33, and a gap also needs to be left between the second limiting disc 32 and the corresponding positioning member 33. The staff adjusts the adjusting assembly 5 to synchronously adjust the positions of the two positioning members 33 on the guide shaft 1. Synchronously adjusting the two positioning members 33 can be understood as the two positioning members 33 moving left or right synchronously, and the distance between the two positioning members 33 does not change, so as to ensure that there is still enough space between the two positioning members 33 to accommodate the first limiting disc 31, the second limiting disc 32 and the rotating member 2, and there is enough gap required for rotation.

[0051] In some embodiments, the adhesive tape cylinder fixing device further includes an adjusting assembly 5. The adjusting assembly 5 includes: two nuts 51, and the two nuts 51 are respectively connected to the two positioning members 33; a screw rod 52 is provided on the guide shaft 1, and the screw rod 52 is threadedly connected to the nut 51. Thus, the adjusting assembly 5 adopts thread adjustment, which can provide more precise displacement control, achieve micron-level adjustment, and ensure the precise position of the adhesive tape cylinder 100 in the adhesive tape cylinder fixing device. In addition, the thread has self-locking property. After the positions of the two positioning members 33 are adjusted, the positioning members 33 can be stably maintained at the target positions.

[0052] Specifically, the staff can drive the first limiting disc 31, the second limiting disc 32 and the rotating member 2 between the two positioning members 33 to move on the guiding shaft 1 through the adjusting assembly 5. In practical applications, after the adhesive tape cylinder 100 is sleeved on the adhesive tape cylinder fixing device, there may be an offset between the adhesive tape cylinder 100 and the profile to be packaged. For example, the adhesive tape cylinder 100 is slightly to the left, while the profile to be packaged is to the right. Refer to Figure 12 , in the related art, usually one side of the fixing gasket 8 is manually pushed to push the adhesive tape cylinder 100 to a suitable position on the guiding shaft 1. The adjustment accuracy is usually 1 mm. If the adjustment is not in place, the staff needs to manually adjust it repeatedly. In this application, through the cooperation of the nut 51 and the screw 52 of the adjusting assembly 5, the staff can more accurately adjust the position of the adhesive tape cylinder 100, and the accuracy can reach 0.1 mm, which is much higher than the traditional manual adjustment method, making the alignment between the adhesive tape cylinder 100 and the profile to be packaged more accurate. The staff can quickly adjust the adhesive tape cylinder 100 to the ideal position, reducing the adjustment time and improving the overall efficiency of the packaging line.

[0053] In some embodiments, an adjusting handle 54 and a mounting seat 6 are respectively arranged at both ends of the guiding shaft 1. The adjusting handle 54 is located at the insertion end of the adhesive tape cylinder fixing device, and the adjusting handle 54 is connected to the end of the screw 52. The staff can rotate the adjusting handle 54 to rotate the screw 52, so that the screw 52 drives the two nuts 51 to move, completing the position adjustment of the adhesive tape cylinder 100. The mounting seat 6 is used for mounting on an external profile adhesive tape packaging device.

[0054] Refer to Figure 9 , in some embodiments, the guiding shaft 1 is internally provided with an accommodating space, and the guiding shaft 1 is further provided with a guiding groove 11 communicating with the accommodating space. The guiding groove 11 extends along the axial direction of the guiding shaft 1; the nut 51 is located inside the guiding shaft 1, and along the axial direction of the guiding shaft 1, the screw 52 penetrates through the guiding shaft 1 and is threadedly connected to the nut 51; the adjusting assembly 5 further includes a guiding member 53, one end of the guiding member 53 is connected to the nut 51, and the other end of the guiding member 53 penetrates through the guiding groove 11. Thus, in this embodiment, by placing the nut 51 and the screw 52 into the guiding shaft 1, the internal space of the guiding shaft 1 can be fully utilized, making the structure of the adhesive tape cylinder fixing device more compact. And by hiding the nut 51 and the screw 52 inside the guiding shaft 1, the external structure of the adhesive tape cylinder 100 can also be made more concise without affecting the insertion of the adhesive tape cylinder 100. In addition, the setting of the guiding groove 11 can not only enable the nut 51 inside the guiding shaft 1 to be connected to the positioning member 33, but also the guiding groove 11 can play a guiding role in the movement of the positioning member 33. The guiding member 53 can move along the guiding groove 11, thereby limiting the movement of the positioning member 33 along the extending direction of the guiding groove 11 and avoiding the situation where the positioning member 33 rotates around the guiding shaft 1.

[0055] In some embodiments, the guiding shaft 1 is provided with a plurality of guiding grooves 11 which are spaced apart from each other and arranged circumferentially around the guiding shaft 1. The adjusting assembly 5 includes a plurality of guiding members 53, and the number of the guiding members 53 corresponds to that of the guiding grooves 11. Thus, the guiding effect is better due to the arrangement of the plurality of guiding grooves 11 and the guiding members 53.

[0056] In some embodiments, it further includes: a pressure sensor disposed on the contact surface between the tensioning assembly and the inner wall of the adhesive tape cylinder for collecting the contact pressure value in real time; a controller that generates an adjustment amount based on a preset pressure threshold range and the contact pressure value, and drives the adjusting assembly to adjust the position of the limiting assembly according to the adjustment amount so that the contact pressure value dynamically converges within the threshold range; wherein, the controller constructs a decision model based on deep reinforcement learning for outputting the adjustment amount; the decision model uses the time series data of the contact pressure value as the state space, uses the displacement direction and step size of the limiting assembly as the action space, and designs a reward function according to the state space and the action space; the reward function is used to output a positive reward when the contact pressure value falls within the pressure threshold range, and generate a negative penalty according to the deviation amplitude when it exceeds the pressure threshold range.

[0057] The embodiment provides an adhesive tape cylinder fixing device with an intelligent pressure adjustment function, which dynamically senses the contact pressure between the tensioning assembly and the inner wall of the adhesive tape cylinder, and realizes adaptive adjustment based on the deep reinforcement learning algorithm to ensure that the pressure value is stably within the preset threshold range.

[0058] By arranging a pressure sensor on the contact surface between the tensioning assembly and the inner wall of the adhesive tape cylinder, the contact pressure value is collected in real time to form a pressure feedback signal. After receiving the pressure signal, the controller determines whether the current pressure deviates from the target range through a preset pressure threshold range (such as 1.5 - 2.5 N).

[0059] State space: Using the time series pressure data collected by the pressure sensor (such as the pressure fluctuation curve in the past 5 seconds) as the model input to capture the dynamic change trend. Action space: Defining the displacement direction (left shift / right shift) and step size (0.1 mm / step or 0.5 mm / step) of the adjusting assembly, and changing the elastic deformation amount of the tensioning assembly by finely adjusting the position of the limiting assembly.

[0060] Reward function: Positive reward: When the pressure value falls within the threshold range, a fixed reward value (such as +10) is output to encourage the model to maintain a stable state. Negative penalty: If the pressure exceeds the threshold, a gradient penalty (such as -ΔP × coefficient) is generated according to the deviation magnitude (for example, the pressure difference ΔP = |actual value - threshold boundary|). The greater the deviation, the higher the penalty, driving the model to correct quickly. The design of the reward function includes: establishing a time decay factor α(t) to weighted sum the historical sequential pressure values, constructing a state space vector S_t = [α(t - k)·p_{t - k}, …, α(t)·p_t], where p_t represents the contact pressure value at time t, and k is the preset time window length; discretizing the action space into three displacement directions: positive fine-tuning, negative fine-tuning, and maintaining, and setting multi-level adjustable step size parameters; when the contact pressure value falls into the middle safety zone of the pressure threshold range, a dynamic reward value positively correlated with the stable duration of the current pressure value is given; when the contact pressure value exceeds the threshold range, a penalty term R_p = -e^{γ·Δp} is generated according to the distance between the deviation amount Δp and the threshold boundary, where γ is the penalty coefficient; setting a continuity reward condition, when N consecutive sequential pressure values are all within the threshold range, an additional stability reward value R_s = β·N is triggered, where β is the reward gain coefficient.

[0061] The adjustment component adopts a servo motor + screw drive structure. After receiving the displacement instruction from the controller, it drives the limit component to move precisely along the guide shaft to achieve the dynamic balance of the tension force.

[0062] When installing the adhesive tape cylinder, the tensioning component expands outward under the action of the elastic force and initially compresses the inner wall. The pressure sensor transmits the contact pressure to the controller in real time. The operator sets the pressure threshold range (such as 1.8 - 2.2N) through the human-machine interface and selects the decision model training mode (online learning / offline pre-training). The pressure sensor collects the contact pressure at a frequency of 100Hz to generate a sequential data stream. The controller inputs the pressure sequential data into a pre-trained deep reinforcement learning model (such as a DQN network), and the model outputs the current optimal action (displacement direction and step size). If the pressure continues to be lower than the lower limit, the model decides to "move right 0.3mm" to increase the tension force. The servo motor of the adjustment component executes the displacement instruction, drives the limit component to move, and changes the elastic deformation degree of the tensioning component. The pressure sensor updates the pressure value, and the controller calculates the reward value in the new state and updates the model parameters (in the online learning mode).

[0063] By simulating different working conditions such as the diameter of the adhesive tape cylinder and the material stiffness in the simulation environment, the initial strategy of the model is trained through millions of trial-and-error. After being deployed to the actual device, the model further optimizes the strategy according to the real-time pressure data to adapt to the dynamic disturbances of a specific production line (such as the fluctuation of the adhesive tape thickness).

[0064] Exemplarily, driving the adjustment component to adjust the position of the limit component according to the adjustment amount includes: solving the adjustment amount according to the rolling horizon optimization method to obtain a multi-step position adjustment sequence, and constraining the position change rate corresponding to the multi-step position adjustment sequence based on the Lyapunov stability condition; controlling the servo motor of the adjustment component to execute the multi-step position adjustment sequence to adjust the position of the limit component.

[0065] The controller starts from the current pressure value Pt and establishes a dynamic model in combination with the inertial characteristics of the adhesive tape cylinder (such as moment of inertia, friction coefficient) to predict the pressure change trajectory in the next 5 steps (the time window length can be set, such as 0.1 second per step). Objective function design: Minimize the pressure deviation and the adjustment energy consumption , where ut+k is the displacement command at the k-th step. Using quadratic programming (QP) or model predictive control (MPC) algorithms to solve the optimal displacement sequence {u t+1 , u t+2 ,..., u t+5} that satisfies the constraint conditions. Define the Lyapunov function V(x) = 1 / 2(P - P target ) 2 , which characterizes the energy state of the system. The servo motor of the adjustment component receives the displacement sequence command and drives the limit component to move according to a preset period (such as executing one step every 0.1 second). The actual displacement value is feedback in real time through the encoder. If an execution deviation (such as mechanical jamming) is detected, the sequence is re-planned to ensure the adjustment accuracy of ±0.05 mm.

[0066] It should be noted that in some embodiments, after controlling the servo motor of the adjustment component to execute the multi-step position adjustment sequence to adjust the position of the limit component, it further includes updating the weight parameters of the corresponding policy network of the decision model through online incremental learning to make the decision model adapt to the contact pressure decay curve of adhesive tape cylinders with different diameters.

[0067] When the change in the diameter of the adhesive tape cylinder is detected (e.g., the inner diameter difference of a new batch ≥ 3 mm) or the shape of the pressure decay curve is abnormal (e.g., the decay rate exceeds 20% of the historical value), the online learning module is activated. Store the latest 100 sets of adjustment process data (including pressure time series, displacement commands, and reward values), and preferentially retain the key samples with high rewards / high penalties. Use the Elastic Weight Consolidation (EWC) algorithm to constrain the modification range of important parameters for historical tasks when updating the weights of the policy network, preventing catastrophic forgetting. Perform Fourier transform on the contact pressure decay curves of adhesive tape cylinders with different diameters, and extract features such as the proportion of low-frequency energy and decay time constant. Add a diameter condition input branch to the hidden layer of the model, and dynamically adjust the neuron connection weights through a gating mechanism to achieve "one network for multiple uses". Online learning enables the model to adapt to a new-diameter adhesive tape cylinder within 10 - 15 adjustment cycles (about 2 - 3 minutes) without retraining.

[0068] The present application also provides a profile adhesive tape packaging device, which includes an adhesive tape cylinder fixing device on it.

[0069] In some embodiments, the profile adhesive tape packaging device includes a frame and an offset monitoring sensing module; the offset monitoring sensing module is disposed on the frame and is used to monitor in real time the relative position offset between the output adhesive tape cylinder 100 of the adhesive tape cylinder and the profile to be packaged, so as to cooperate with the adjustment component 5 of the adhesive tape cylinder fixing device to automatically achieve fine adjustment and correction of the fitting position. Specifically, the end of the screw rod 52 facing the insertion end is connected to the motor 7, and the motor 7 is installed on the guide shaft 1. The offset monitoring sensor can monitor the offset between the adhesive tape cylinder 100 and the profile to be packaged and output a corresponding adjustment instruction. The adjustment instruction includes adjusting the adhesive tape cylinder 100 in the target direction and the target adjustment amount output according to the offset amount. The motor 7 is used to receive the adjustment instruction output from the offset monitoring sensor.

[0070] For example, if the adhesive tape cylinder 100 is offset 0.2 mm to the left relative to the profile to be packaged, the offset monitoring sensor issues a corresponding adjustment instruction. The motor 7 receives the adjustment instruction, and the controller of the profile adhesive tape packaging device controls the motor 7 to rotate. The output end of the motor 7 drives the screw rod 52 to rotate, so as to move the two positioning members 33, thereby adjusting the adhesive tape cylinder 100 0.2 mm to the right. Thus, automatic fine adjustment and correction of the position of the adhesive tape cylinder 100 can be achieved.

[0071] In some embodiments, the offset monitoring sensor can be located above or on the side of the fitting point between the output end of the adhesive tape cylinder 100 and the profile, facing the fitting area of the adhesive tape and the profile. The offset monitoring sensor can be a laser displacement sensor, a linear CCD, a vision camera module, etc., and the user can make a comprehensive evaluation according to specific situations such as cost budget to select the most suitable offset monitoring sensor.

[0072] In some embodiments, the offset monitoring sensor collects the real-time position data of the adhesive tape and the profile at a frequency of 100 Hz. When the detected offset exceeds the threshold, a control signal is triggered. The control unit calculates the adjustment amount according to the offset direction (left / right / front / rear), and drives the corresponding stepper motor to rotate the corresponding number of steps. The screw drives the nut to move, and through the guide, the limiting component is pushed to slide along the guide shaft, so that the rotating component and the tensioning component are displaced as a whole, and the axial position of the adhesive tape cylinder is corrected.

[0073] The expression of the adjustment amount includes: ΔL = K_p·(Δx·cosθ + Δy·sinθ); where, ΔL is the correction distance that the adjustment component needs to move (unit: mm), and a positive value indicates moving to the right side of the frame. K_p is the proportionality coefficient, with a value range of 0.8 - 1.2, which is calibrated according to the device response speed. Δx is the horizontal lateral offset between the adhesive tape and the profile (unit: mm), negative for left deviation and positive for right deviation. Δy is the vertical longitudinal offset between the adhesive tape and the profile (unit: mm), negative for lag and positive for lead. θ is the angle between the axis of the adhesive tape cylinder and the traveling direction of the profile (unit: °), and it is default to be orthogonally installed at 90°.

[0074] Assume that Δx = +2 mm (right deviation), Δy = -1 mm (lag), θ = 90°, and K_p = 1.0, then: ΔL = 1.0×(2×cos90° + (-1)×sin90°) = 1.0×(0 - 1) = -1 mm; that is, the adjustment component needs to move 1 mm to the left, and the adhesive tape cylinder is driven to reset by the reverse rotation of the screw. Furthermore, this implementation realizes sub-millimeter-level dynamic deviation correction, greatly reducing the packaging misalignment rate, and at the same time ensuring the precise matching of the correction direction and the offset direction through the formulated control logic.

[0075] Since traditional deviation correction relies on a fixed proportionality coefficient (such as K_p above), but in actual working conditions, changes in the adhesive tape tension and the weight of the cylinder will cause the system response to be non-linear. Therefore, the PID parameters can also be optimized through real-time data closed-loop to achieve dynamic adaptive adjustment. Exemplarily, a tension sensor (installed on the adhesive tape output path) and a pressure sensor (embedded on the surface of the pressing member of the tensioning component) are added to the offset monitoring sensing module to collect the adhesive tape tension F (N) and the pressing pressure P (Pa) in real time. The input parameters for constructing the adaptive PID algorithm module include Δx, Δy, F, P, and the output is the stepper motor pulse frequency f (Hz) and the rotation direction.

[0076] The PID output (pulse number N) is calculated by the following formula: N = K_p(t)·e(t) + K_i(t)∫e(t)dt + K_d(t)·de(t) / dt; e(t) is the real-time offset error, e(t)=√(Δx²+Δy²); K_p(t), K_i(t), and K_d(t) are dynamically adjusted PID coefficients, which are optimized online by the gradient descent method, and the objective function is to minimize the integral of the error (∫e²(t)dt).

[0077] Meanwhile, the PID parameters are corrected according to the tension and pressure data. When F>50N or P>200kPa, K_d is increased to suppress overshoot; when F<20N, K_i is increased to accelerate the elimination of the steady-state error.

[0078] Exemplarily, a control unit is provided between the offset monitoring and sensing module and the adjustment component; the control unit is configured to synchronously optimize the rectification accuracy of the adhesive tape cylinder, the energy consumption of the adjustment component, and the wear state of the mechanical components based on the real-time operation data of the adhesive tape cylinder; the real-time operation data includes the current value of the stepper motor, the friction coefficient between the guide shaft and the rotating part, and the fatigue coefficient of the spring in the tensioning component.

[0079] The current sensor is connected in series to the power supply circuit of the stepper motor to collect the working current of the motor Imotor (unit: A) in real time, which is used to calculate the energy consumption index.

[0080] The friction coefficient estimation module estimates the friction coefficient μ=τ / (r⋅Fr) according to the output torque τ of the stepper motor (calculated by the current-torque relationship τ=kt⋅Imotor, where kt is the motor torque constant) and the radial force Fr on the guide shaft (deduced by the pressing pressure of the tensioning component), where r is the radius of the rotating part. The spring fatigue is monitored by detecting the compression cycle number Ncycles of the spring in the tensioning component by a Hall sensor, and the fatigue coefficient η=1−Ncycles / 106 is calculated.

[0081] The provided control unit is built-in with a multi-objective optimization algorithm module, with the inputs being Imotor, μ, η, and the output being the dynamically adjusted values of the PID control parameters Kp, Ki, Kd.

[0082] The multi-objective optimization algorithm module includes:

[0083] Optimization objective definition:

[0084] Objective 1 (rectification accuracy): Minimize the integral of the adhesive tape offset error J1=∫(∣Δx∣+∣Δy∣) dt.

[0085] Objective 2 (energy consumption): Minimize the motor power consumption \(J_2=\int I_{motor}^2\cdot R\ dt\), where \(R = 0.5\ \Omega\) is the internal resistance of the motor.

[0086] Objective 3 (lifespan): Maximize the system lifespan \(J_3=\int(\mu\cdot\eta)\ dt\), where a larger value indicates lower wear.

[0087] Constraints: The rectification accuracy needs to satisfy \(|\Delta x|\leq1\ mm\) and \(|\Delta y|\leq0.5\ mm\); the motor current does not exceed the rated value \(I_{motor}\leq2\ A\).

[0088] Optimization algorithm process: Step 1: Load the Pareto optimal solution set of typical working conditions (such as "high-speed packaging mode", "high-load mode", "low-temperature environment mode") from the historical database. Step 2: Real-time collect \(I_{motor}\), \(\mu\), \(\eta\), and determine the current working condition category through K-means clustering. Step 3: Select the corresponding optimal PID parameter combination \([K_p, K_i, K_d]\) according to the working condition category. Step 4: If the current objective weight needs to be adjusted (for example, giving priority to ensuring accuracy or energy conservation), switch according to the following rules: When \(J_1>1\ mm\cdot s\), select the accuracy-priority parameters; when \(J_2>1.5\ W\cdot s\), select the energy-consumption-priority parameters; when \(J_3<0.7\), select the lifespan-priority parameters.

[0089] Assume the device is operating in the "low-temperature environment mode" (\(\eta = 0.6\)). The control unit loads the optimized parameters \(K_p = 0.9\), \(K_i = 0.05\), \(K_d = 0.1\) for this working condition from the database. It is detected in real-time that \(\mu\) increases from \(0.1\) to \(0.15\) (due to decreased lubrication at low temperature), triggering parameter recalibration: Search for the optimal solution that satisfies \(\mu = 0.15\) in the solution set through the particle swarm algorithm, and update to \(K_p = 0.8\), \(K_i = 0.06\), \(K_d = 0.08\). The adjustment component drives according to the new parameters, causing the motor current to decrease by 10% while maintaining the rectification accuracy \(|\Delta x|\leq0.8\ mm\).

[0090] Furthermore, on the premise of ensuring accuracy, the average motor power consumption is reduced. By suppressing the \(K_d\) value under high-friction working conditions, the wear rate of the rotating parts is reduced by 40%. In the ambient temperature range of -10°C to 50°C, the control unit automatically switches to the optimal parameter combination without manual intervention.

[0091] In summary, in the adhesive tape cylinder fixing device provided in the present application, after the staff fixes the adhesive tape cylinder 100 to the adhesive tape cylinder fixing device, the elastic restoring force of the tensioning assembly 4 can abut against the inner wall of the adhesive tape cylinder 100, thereby realizing the fixing of the adhesive tape cylinder 100. When it is necessary to remove the adhesive tape cylinder 100, a slight external force can be applied to remove the adhesive tape cylinder 100. In this way, during the process of placing and removing the adhesive tape cylinder 100, there is no need to disassemble any additional components, and the entire operation process is convenient and fast. In addition, compared with the traditional fixing device, which needs to block both ends of the adhesive tape cylinder 100 through the fixing gasket 8 to achieve fixation, and in order to ensure that the adhesive tape cylinder 100 can rotate smoothly, it is also necessary to adjust the gap between the fixing gasket 8 and the adhesive tape cylinder 100. However, the adhesive tape cylinder fixing device provided in the present application omits the work of adjusting the gap between the adhesive tape cylinder 100 and the fixing gasket 8 by the way that the tensioning assembly 4 abuts against the inner wall of the adhesive tape cylinder 100, has a lower requirement for the operation skills of the staff, and is also beneficial to improving the operation efficiency.
