Description

Technical Field

[0001] This invention relates to the technology for conveying strip staple wire sheet materials, and more specifically, to a method for controlling the synchronous conveying of staple wire bundles in a double-winding manner, and to a system for synchronous conveying of staple wire bundles in a double-winding manner. Background Technology

[0002] Staples, a widely used office stationery item, are produced from prefabricated wire bundles. These bundles are made by bonding dozens of parallel galvanized iron wires together with adhesive, hot-pressing, and drying. The resulting staples are then cut to length and stamped into finished products. The quality of the wire bundle winding directly affects the precision of subsequent forming processes and the product yield. Traditional single-line production lines produce only one roll of wire bundle, with the winding reel providing power for the entire line. Precise speed control is not required, and small speed fluctuations do not affect production.

[0003] Because the width of the staple wire sheet is smaller than the width allowed by the production line during the production process of staple wire sheets, for example, the width of ordinary staple wire sheets is usually around 5cm-10cm; while the width allowed by the production line of staple wire sheets is usually more than 20cm. This will result in the traditional staple wire sheet production line being in normal operation, but its actual utilization rate is usually only half.

[0004] To significantly increase production capacity, dual-path parallel production can be implemented in the traditional production line. This involves producing two sets of identical filament sheets on the same production line, passing them through the same gluing and drying device, and finally winding them up by two independent winding wheels.

[0005] However, in this double-width production process, the two sets of wire bundles need to be highly synchronized. If there is a difference in the winding speed of the two sets of wire bundles, the faster winding will drag the pressure roller to rotate faster, causing the slower winding to slide relative to the surface of the pressure roller. This sliding friction will scrape off the adhesive layer on the surface of the wire bundle, destroy the bonding structure between the metal wires, and in severe cases, cause the wire bundle to scatter and break, resulting in the scrapping of the entire roll of product.

[0006] Therefore, a new technical solution is needed to address the aforementioned technical problems. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method and system for synchronous conveying control of two sets of staple wire bundles, which can realize synchronous winding control of two sets of staple wire bundles.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A method for controlling the synchronous double-winding conveying of staple wire bundles includes the following steps:

[0010] Step S1: Construct a virtual take-up reference axis by inputting the standard initial roll diameter, standard wire sheet thickness parameters, and standard linear speed. ;

[0011] Step S2: Define the rotational speed coupling coefficients between the virtual reference axis and the first and second take-up reels as follows: , Establish a speed mapping relationship. , The initial values ​​are all set to 1;

[0012] Step S3: Enter the pre-calibration stage, controlling the production line to not exceed... During low-speed operation, the cumulative number of turns and real-time outer diameter data of the two winding wheels are collected;

[0013] Step S4: Calculate the actual effective winding thickness of the two wire bundle plates based on the collected data, correct the operating parameters of the virtual reference axis, and iteratively calibrate the initial speed coupling coefficient. , ;

[0014] Step S5: Obtain the winding speed of the two winding rollers. When the relative deviation between the two winding speeds and the virtual reference axis speed is less than the preset threshold, the pre-calibration is completed and the production line automatically switches to the normal production stage.

[0015] Furthermore, it also includes the following steps:

[0016] Step S6: During normal production, the actual rotational speed of the shared pressure roller and the operating speed of the two winding wheels are collected in real time, and the speed coupling coefficient is dynamically adjusted based on the virtual reference axis. , This enables continuous synchronization of the two winding paths.

[0017] Furthermore, in step S1, the rotational speed model of the virtual reference shaft is:

[0018]

[0019] in, Winding up for virtual reference axis Target rotational speed during revolution; Winding up for virtual reference axis The virtual scroll diameter during looping, for:

[0020]

[0021] in, As the virtual initial empty volume diameter, For virtual single-layer thickness of the circuit board, This represents the virtual cumulative number of rolls.

[0022] Furthermore, in step S4, the actual effective winding thickness is calculated as follows:

[0023] During the winding process, at intervals of several winding turns, the outer diameter variable value of the corresponding winding wheel is recorded, and the average outer diameter increment per turn of the two wire bundle plates within that interval is calculated. , The actual effective winding thickness of the two wire bundle plates was obtained. , .

[0024] Furthermore, in step S4, the method for correcting the operating parameters of the virtual reference axis is as follows: calculate the average value of the actual effective winding thickness of the two paths. and the average of the initial empty diameters of the two take-up reels. ;

[0025] Will and Replace the virtual reference axis model respectively and Corrections completed.

[0026] Further, in step S4, the initial rotational speed coupling coefficient is iteratively calibrated. , The method is as follows:

[0027] Set pre-calibration adjustment step size The linear velocity of the virtual reference axis is used as a reference.

[0028] If the actual linear speed of the winding reel is higher than the reference value, its coupling coefficient is reduced proportionally; if the actual linear speed of the winding reel is lower than the reference value, its coupling coefficient is increased proportionally.

[0029] Iterative adjustments are made until the relative deviations of the speeds of both routes from the baseline value are less than 5%, and the current coupling coefficient is locked as the initial value.

[0030] Furthermore, in step S6, the rotational speed coupling coefficient is dynamically adjusted. , The method is as follows:

[0031] The rotational speed of the shared pressure roller between the two winding paths is collected in real time to obtain the linear velocity of the shared pressure roller. Real-time calculation of the actual linear velocity of the two winding paths. , ;

[0032] when Time adjustment , for:

[0033]

[0034] when Time adjustment , for:

[0035]

[0036] in, The set dynamic compensation threshold, This is the set dynamic compensation step size.

[0037] Furthermore, it also includes the following steps:

[0038] Step S7: Slippage warning and emergency response, when the linear speed of any winding line and the linear speed of the shared pressure roller... The absolute value of the deviation exceeds the preload threshold. If the duration exceeds 1 second, it is determined that slippage has occurred, and a warning signal is issued;

[0039] The dynamic compensation step size corresponding to the winding reel Increased by 2 times, quickly eliminating speed deviation.

[0040] Furthermore, the winding of the two wire bundles uses a common pressure roller. An encoder is installed at the shaft of the common pressure roller to collect the rotation speed of the common pressure roller. Based on the rotation speed of the common pressure roller, the actual linear velocity of the outer circumference of the common pressure roller can be obtained.

[0041] The present invention also provides a double-winding synchronous conveying system for staple wire bundles, including a production line for staple wire bundles. The production line for staple wire bundles includes a non-powered common pressure roller and independently driven first winding rollers and second winding rollers. The first winding rollers and second winding rollers are driven to rotate by first servo motors and second servo motors, respectively.

[0042] An encoder is installed at the shaft of the common pressure roller to collect the rotational speed of the common pressure roller. Based on the rotational speed of the common pressure roller, the actual linear velocity of the outer circumference of the common pressure roller can be obtained.

[0043] The control is achieved using the aforementioned method of synchronous conveying and double-winding of staple wire bundles.

[0044] In summary, the present invention has the following beneficial effects:

[0045] By dynamically balancing the two sets of take-up rollers, dynamic stability can be maintained during the take-up process, avoiding speed deviations in traditional dual-path control. Combined with pre-calibration and dynamic fine-tuning, the take-up speeds of the two paths remain highly consistent, fundamentally eliminating relative slippage between the wire plate and the pressure roller, and avoiding problems such as adhesive layer scratches and wire plate fraying.

[0046] By automatically measuring the actual effective winding thickness during the pre-calibration stage, it can adapt to variations in wire diameter, adhesive thickness, and winding tightness across different batches, eliminating the need for frequent manual parameter adjustments. Pre-calibration automatically collects actual data to correct the virtual model and coupling coefficients, enabling automatic adaptation to changes in production conditions, improving automatic adjustment during equipment operation, and enhancing production stability.

[0047] By constructing a pre-set virtual model, the rotation speed change trend of the entire winding process can be calculated in advance. Dynamic compensation only handles small random errors and can eliminate the lag problem in the control process to a certain extent. Attached Figure Description

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] This embodiment discloses a double-winding synchronous conveying system for staple wire bundles, suitable for use in production lines for staple wire bundles. (Refer to...) Figure 1 , Figure 2 As shown, the production line for staple wire bundles includes a first take-up roller 1, a second take-up roller 2, an adhesive applicator 3, a drying device 4, and several common pressure rollers 5.

[0054] In the production process of ordinary staple wire bundle boards, two sets of wire bundle boards are produced simultaneously on the original production line. The two sets of wire bundle boards pass through the gluing device 3 and the drying device 4 in sequence for gluing and drying, thus forming two sets of wire bundle boards respectively. Then, the first winding roller 1 and the second winding roller 2 respectively wind up the two sets of wire bundle boards, so that two sets of wire bundle boards can be produced simultaneously on one production line, improving production efficiency.

[0055] In addition, the production line is also equipped with several sets of non-powered shared pressure rollers 5. Each set of shared pressure rollers 5 has two rollers, which can simultaneously apply vertical force to the filament bundle plate, thereby maintaining smooth conveying.

[0056] The first winding roller 1 and the second winding roller 2 are driven independently by the first servo driver 11 and the second servo driver 21, respectively, thereby controlling the smoothness of the two sets of filament sheets during the winding and conveying process, and ensuring that the linear speed of the two sets of filament sheets can be kept relatively stable.

[0057] In this embodiment, an encoder is installed at the shaft of one set of common pressure rollers 5 to collect the rotational speed of the common pressure rollers 5. Based on the rotational speed of the common pressure rollers 5 and combined with the outer diameter parameters of the common pressure rollers 5, the actual linear velocity of the outer circumference of the common pressure rollers 5 can be obtained.

[0058] During operation, if there is a difference in linear speed between the two sets of wire bundle plates, the smoothness of the production line will decrease. The set of wire bundle plates with a faster winding speed will have greater tension, causing bending and deviation during the winding process. Moreover, since the shared pressure roller 5 presses against both sets of wire bundle plates simultaneously, the different linear speeds will cause one of the wire bundle plates to slip against the shared pressure roller 5. This slippage will cause wear on the surface of the wire bundle plate, affecting the quality of the final staples.

[0059] Moreover, during operation, the system in this embodiment is controlled by a dual-winding synchronous conveying control method, which can establish the speed coupling coefficient between the virtual reference axis and the two winding wheels. First, it enters the pre-calibration operation stage to collect actual production data to correct the virtual reference axis model and calibrate the initial coupling coefficient. Then, it switches to the normal production stage to dynamically fine-tune the coupling coefficient, so that the speed of the two winding lines always changes synchronously with the virtual reference axis, ensuring that the two sets of filament wire plates and the common pressure roller 5 maintain static friction without relative sliding.

[0060] This embodiment also discloses a method for controlling the synchronous conveying of staple wire bundles in a double-rewinding manner, which can control the synchronous conveying system of staple wire bundles in the above embodiment and dynamically balance the wire feeding smoothness of the two sets of wire bundles; specifically, the control method in this embodiment includes the following steps:

[0061] Step S1: Construct a virtual take-up reference axis

[0062] The virtual take-up reference axis is a virtual control reference constructed purely in software and has no physical structure. Its function is to provide a unified speed reference standard for the two independent take-up wheels, so as to avoid speed deviation caused by the independent control of the two take-up wheels.

[0063] Input the standard initial roll diameter, standard wire plate thickness parameters, and standard linear velocity. The standard initial roll diameter is determined by the take-up reel used in the production process, along with the standard wire plate thickness and standard linear speed. The parameters are determined by the production process requirements of the filament bundle and the wire plate; all three are pre-set theoretical parameters.

[0064] In step S1, the rotational speed model of the virtual reference shaft is:

[0065]

[0066] in, Winding up for virtual reference axis Target rotational speed during revolution; Winding up for virtual reference axis The virtual scroll diameter during looping, for:

[0067]

[0068] in, As the virtual initial empty volume diameter, For virtual single-layer thickness of the circuit board, This represents the virtual cumulative number of rolls.

[0069] In this virtual reference shaft speed model, the target speed of the virtual reference shaft is calculated in advance based on the change in the number of winding turns. Increase virtual volume The target rotational speed increases linearly, based on the principle of constant linear velocity. The speed needs to be reduced synchronously to achieve pre-calculation and pre-adjustment of the rotational speed, thus avoiding the lag problem of correction in traditional control.

[0070] Step S2: Establish speed mapping relationship

[0071] Define the rotational speed coupling coefficients between the virtual reference axis and the first take-up reel 1 and the second take-up reel 2 as follows: , Establish a rotational speed mapping relationship. Specifically, , The initial values ​​of all three are set to 1, meaning that in the initial ideal state, there is no error among the three, and they maintain synchronous transmission.

[0072] The rotational speed coupling coefficient is a core parameter connecting the virtual reference axis and the actual winding reels. It maps the target rotational speed of the virtual reference axis to the actual target rotational speed of the two winding reels. The rotational speed coupling coefficient directly reflects the relative relationship between the two winding reels and the virtual reference axis, which facilitates subsequent calibration operations.

[0073] Step S3: Enter the pre-calibration stage

[0074] Control the production line to operate at a low speed, that is, control the production line to operate at a speed not exceeding... , The speed is typically 5 m / min. At low speeds, the cumulative number of revolutions and real-time outer diameter data of the two winding reels are collected.

[0075] Specifically, the outer diameter data can be obtained using infrared detection equipment to acquire the outer diameter of the winding wheel (including the outer circumferentially wound wire sheet). The accumulated number of turns is used to calculate the winding progress, while the real-time outer diameter data is used to subsequently calculate the actual thickness of the wire sheet, providing data support for the correction of the virtual reference axis parameters.

[0076] Step S4: Correct parameters and calibrate coupling coefficient

[0077] Based on the collected data, the actual effective winding thickness of the two wire bundle plates is calculated, the operating parameters of the virtual reference axis are corrected, and the initial speed coupling coefficient is iteratively calibrated. , ;

[0078] Specifically, in step S4, the actual effective winding thickness is calculated as follows:

[0079] During the winding process, at intervals of a certain number of winding turns (usually set to 10 turns), the outer diameter variable value of the corresponding winding wheel is recorded, and the average outer diameter increment per turn of the two wire bundle plates within this interval is calculated. , , , This is the value obtained based on the total variable value and the number of winding turns; at this point, the average outer diameter increment per turn is obtained. , The outer diameter varies, being twice that of a single-layer wire bundle plate. The actual effective winding thickness of the two wire bundle plates can be calculated. , . Specifically, , .

[0080] Specifically, in step S4, the method for correcting the operating parameters of the virtual reference axis is as follows:

[0081] Calculate the average of the actual effective winding thickness of the two paths. and the average of the initial empty diameters of the two take-up reels. ;

[0082] Will and Replace the virtual reference axis model respectively and Corrections completed.

[0083] By averaging the winding parameters of the two sets of filament bundle plates, the influence of thickness differences between the two plates on the virtual model can be eliminated, making the parameters of the virtual reference axis more universal. Using the average of the initial empty roll diameters of the two winding wheels eliminates the influence of paper core processing errors on the winding wheels, ensuring that the initial value of the virtual roll diameter is consistent with actual production conditions.

[0084] By modifying the virtual reference axis model, the modified model can better fit actual production, improve the accuracy of subsequent speed control, and enable it to adapt to different production stages.

[0085] Specifically, in step S4, the initial rotational speed coupling coefficient is iteratively calibrated. , The method is as follows:

[0086] Set pre-calibration adjustment step size , It is usually set to 0.01, with the linear velocity of the virtual reference axis as a reference; iterative compensation is performed with a small value to avoid abrupt changes in a single compensation.

[0087] Compare the actual linear velocity of the corresponding winding reel with the winding linear velocity of the virtual reference axis. If the actual linear velocity of the winding reel is higher, decrease its coupling coefficient proportionally; if the actual linear velocity of the winding reel is lower, increase its coupling coefficient proportionally.

[0088] Adjust the step size according to the pre-calibration each time. The coupling coefficient is iteratively adjusted until the relative deviations between the speeds of both lines and the reference value are less than 5%, at which point the current coupling coefficient is locked as the initial value. Adjusting the coupling coefficient directly changes the target rotational speed of the winding reel, thereby correcting the actual linear speed deviation. The purpose of iterative adjustment is to gradually reduce the deviation until a preset threshold is reached. The locked coupling coefficient is then used as the initial value for normal production, ensuring initial synchronization accuracy.

[0089] Step S5: Complete pre-calibration and switch stages

[0090] The winding speeds of the two winding rollers are obtained. When the relative deviations between the two winding speeds and the virtual reference axis speed are both less than a preset threshold, the pre-calibration is completed and the production line automatically switches to the normal production stage.

[0091] When the relative deviation between the winding speed of one of the wire bundle plates and the speed of the virtual reference axis exceeds a preset threshold, the adjustment is continued through step S4.

[0092] The preset threshold is usually set to a wide range of 1%-2%, meaning that the winding speeds of the two do not need to be absolutely consistent. This preset threshold is determined based on the critical deviation of the yarn bundle plate not slipping. When the deviation is less than this value, it can ensure that the two yarn plates and the shared pressure roller maintain static friction and there is no relative slippage, which ensures both control accuracy and production efficiency.

[0093] Step S6: Dynamic adjustment during normal production phase

[0094] The actual rotational speed of the shared pressure roller 5 and the operating speed of the two winding wheels are collected in real time during the two winding processes, and the speed coupling coefficient is dynamically adjusted based on the virtual reference axis. , This enables continuous synchronization of the two winding paths.

[0095] Specifically, in step S6, the rotational speed coupling coefficient is dynamically adjusted. , The method is as follows:

[0096] The rotational speed of the shared pressure roller 5 for both winding paths is collected in real time to obtain the linear velocity of the shared pressure roller 5. The linear velocity of the shared pressure roller 5 As a real-world benchmark, it can accurately reflect the actual conveying speed of the line plate, and using it as a reference can avoid deviations between the virtual benchmark axis and the actual working conditions.

[0097] By substituting the relevant parameters of the two winding reels, the actual linear speed of the two winding paths is calculated in real time. , :

[0098]

[0099] in, For the first winding reel winding The actual outer diameter at the time of rotation. For the second take-up reel The actual outer diameter at the time of rotation;

[0100] , The initial empty diameter of the first take-up reel. This refers to the actual effective winding thickness of the first winding roller;

[0101] , The initial empty diameter of the second take-up reel. This refers to the actual effective winding thickness of the second winding reel;

[0102] This refers to the real-time actual rotational speed of the first winding reel. This refers to the real-time actual rotational speed of the second winding reel.

[0103] The actual winding linear speed of the corresponding winding reel is compared with the linear speed collected by the common pressure roller. When the actual linear speed of the winding reel is higher than the linear speed collected by the common pressure roller, the rotational speed is reduced by decreasing the coupling coefficient; when the actual linear speed is lower than the linear speed collected by the common pressure roller, the rotational speed is increased by increasing the coupling coefficient to ensure real-time synchronization.

[0104] That is, when Time adjustment , for:

[0105]

[0106] when Time adjustment , for:

[0107]

[0108] in, The set dynamic compensation threshold, This is the set dynamic compensation step size.

[0109] Dynamic compensation threshold The speed is typically set to 0.05 m / min, but the specific value can be determined based on the minimal deviation range that prevents the line plate from slipping. If the deviation exceeds this value, timely adjustment is necessary. Dynamic compensation step size. It is usually set to 0.005, which is smaller than the pre-calibration adjustment step size. The purpose is to achieve fine-tuning and avoid speed fluctuations caused by over-adjustment.

[0110] Furthermore, the synchronous delivery control method in this embodiment also includes the following steps:

[0111] Step S7: Slip Warning and Emergency Handling

[0112] During system operation, the winding linear speed of the two winding rollers is monitored and calculated in real time. When the winding linear speed of any pair of winding rollers is equal to the linear speed of the shared pressure roller 5, the winding linear speed of the two winding rollers is calculated. The absolute value of the deviation exceeds the preload threshold. If the duration exceeds 1 second, it is determined that slippage has occurred, and a warning signal is issued.

[0113] Preload threshold This is the critical deviation for slippage; exceeding this critical deviation indicates slippage has occurred. By using a 1-second duration for judgment, misjudgments caused by instantaneous deviations can be avoided. At this point, the dynamic compensation step size can be adjusted. Increasing the size by at least 2 times can accelerate the adjustment speed, quickly eliminate speed deviations, shorten the duration of slippage, minimize damage to the circuit board, and improve the system's emergency response capabilities.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
