Example (b):
referring to fig. 1 to 3, the present embodiment provides a control system for automatically adjusting the linear density of basalt fiber, which is suitable for use with a bobbin. The bobbin is cylindrical. The inner part of the winding drum is used for connecting a winding rotating shaft or a piece taking head 25, and the outer part of the winding drum is used for winding glass fiber yarns. The control system for realizing the automatic adjustment of the linear density of the basalt fibers comprises a wire drawing machine 3, a material taking assembly 2, a bushing plate and a wire drawing control system. The draw control system includes a controller and load cell 24.
The signal output of load cell 24 is connected to the weight signal input of the controller. The load cell 24 is used to weigh the wound coil 1 and transmit the resulting data to the controller. Load cell 24 may be selected from load cells 24 of model SBT 650.
The controller is used for receiving the data of the weighing sensor 24 and comparing the data of the weighing sensor 24 with the data prestored in the controller so as to judge whether the data of the weighing sensor 24 is standard or not. The controller can be a PLC controller commonly used in the industry.
The bushing plate is matched with a kiln for use. The furnace heats and melts the basalt ore, and the molten basalt ore is leaked into filiform fiber filaments through the leakage holes of the leakage plates. The linear density of the fiber filaments can be controlled by controlling the temperature of the bushing. The bushing plate of the embodiment adopts electric heating, and the controller can conveniently control the temperature of the bushing plate.
The drawing machine 3 is a common drawing machine. The wire drawing machine 3 comprises a wire drawing motor and a winding rotating shaft connected to the wire drawing motor. The winding rotating shaft is matched with the winding drum to enable the winding drum to be fixedly sleeved at one end of the winding rotating shaft. The winding rotating shaft drives the winding drum to rotate, and then the fiber yarns produced by the bushing can be wound.
The take-off assembly 2 includes an X slide shaft 21, a Y slide shaft 22 and a Z slide shaft 23 that cooperate with one another. The lower end of the Z sliding shaft 23 is provided with a weighing sensor 24 and a pickup head 25. The load cell 24 is connected to the Z slide shaft 23 at one end and to the pickup head 25 at the other end. The outer diameter of the pick-up head 25 is smaller than the inner diameter of the bobbin.
When in use, the winding reel is sleeved on the winding rotating shaft. The wire drawing motor rotates to drive the winding rotating shaft to rotate, and then the glass fiber produced by the bushing is wound on the winding reel. The different linear densities, the different lengths of glass fiber filaments required to fully wind a bobbin, and the different winding times. The winding amount of each bobbin can be controlled by the winding time.
And after the winding of the bobbin is finished, the material taking assembly 2 acts. And taking the stub bar to move to the winding drum with the winding completed and go deep into the winding drum, and then lifting the wire coil 1 and placing the wire coil 1 at a stacking position. After the reel 1 is lifted, the load cell 24 measures the weight of the reel 1.
The controller has pre-stored therein the weight of the wet reel corresponding to the linear density of the filaments. The controller compares the measured weight of the wet coil with the data pre-stored in the controller to determine whether the data of the load cell 24 is standard, and thus whether the linear density of the current coil is standard. The data prestored in the controller is the standard weight value of the wet wire coil corresponding to each type of the cellosilk after the standard value of the linear density corresponding to each type of the glass fiber is converted. In practice, the type of the currently produced glass fiber can be input into the controller, and after the controller receives the data of the weighing sensor 24, the controller can compare the obtained data with the standard weight value of the wet wire coil of the corresponding type prestored in the controller to judge whether the weight of the current wet wire coil is standard or not, and further judge whether the linear density is standard or not.
In this embodiment, the lower end of the Z slide shaft 23 is cylindrical, and a steering motor 26 is further provided inside the Z slide shaft. The steering motor 26 has its shaft facing downward. The load cell 24 has one end connected to the rotating shaft of the steering motor 26 and located right below the steering motor 26, and the other end connected to the pickup head 25. The pickup head 25 is connected to one end of the load cell 24 by an L-shaped link 27 so that the pickup head 25 is horizontally disposed.
The steering motor 26 is arranged to enable the pickup head 25 to rotate along with the steering motor 26, and after the pickup head 25 takes the coil 1 off the winding rotating shaft, the pickup head 25 can place the coil 1 at a stacking position at any angle under the cooperation of the pickup assembly. This just makes the setting of stacking position more nimble various, makes things convenient for the arrangement of stacking position.
A control method for realizing the automatic adjustment of the linear density of basalt fibers is matched with the control system for realizing the automatic adjustment of the linear density of basalt fibers. The method comprises the following steps:
s1: the wire drawing machine 3 winds glass fiber and judges whether each coil 1 is full according to the winding length. The type of the glass fiber produced by the wire drawing machine 3 at present is set, and the wire drawing machine 3 automatically judges the length of the glass fiber required by winding the full wire of each winding drum according to the type of the glass fiber. Meanwhile, the winding time of each bobbin can be obtained by combining the winding speed. The drawing machine 3 can determine whether or not the current bobbin is full based on the winding time of each bobbin. After winding of the bobbin is completed, the pick-up head 25 takes the wet coil of wire from the winding spindle and weighs the full coil of wet coil of wire.
S2: the controller calculates a ratio of deviation of the actual weight of each full package of dry yarn from the standard weight of the full package of dry yarn based on the standard moisture content of the package and the weight of the wet package. The standard moisture content of the package and the standard weight of a full package of dry yarn package can be set manually or automatically corrected.
S3: and the controller calculates a bushing temperature adjusting value according to the deviation proportion and the rule value of the influence of the bushing temperature on the line density and adjusts the bushing temperature. Or the controller calculates the rotating speed adjusting value of the wire drawing motor and adjusts the rotating speed of the wire drawing motor according to the deviation proportion and the regular value of the influence of the rotating speed of the wire drawing motor on the linear density.
S4: the number of weighing coils 1 is counted again every time the number of weighing coils 1 reaches a predetermined number. The controller calculates the weight average of the dry reels counted in the current round.
S5: after each round of counting is completed, the controller calculates the difference between the average of the weight of the rolls of dry yarn counted in the round and the standard weight of the full rolls of dry yarn. At the same time, the ratio of this difference to the weight average of the coil 1 counted in the current round is calculated and modified to the value of the standard moisture content.
The method for automatically adjusting the linear density of the basalt fiber by a certain control system for automatically adjusting the linear density of the basalt fiber is exemplified. The standard weight of a full-package dry yarn package of the currently produced glass fiber variety is set to 17.5kg, and the standard moisture content of the package is 10%. If the line density is controlled by adjusting the bushing temperature, the control process is as follows:
in actual production, the weight of the wet coil 1 taken off from the winding spindle by the pick-up head 25 is 20kg, and the system automatically calculates the weight excess ratio of (20 × 90% -17.5)/17.5 to 2.857%, that is, the linear density is 2.857% larger than the standard linear density value. Because the deviation is positive deviation, the bushing plate is automatically cooled, and the temperature of the cooled bushing plate is 2.857%/the temperature of the bushing plate affects the regular value of the linear density. And entering the next adjustment execution cycle according to the next full drum weight result until the linear density deviation is within the allowable range (the set central value is +/-0.5% or other standard ranges), and automatically stopping executing the adjustment action.
When the number of the finished product full-package dry yarns corresponding to the control system for realizing the automatic adjustment of the basalt fiber linear density exceeds 100 rolls (other numbers can be set), the linear density average value of the finished product full package and the finished product full package weight average value are automatically calculated, and the ratio of the finished product linear density average value to the standard linear density (2400) and the ratio of the finished product full package weight average value to the dry yarn standard weight (17.5kg) are calculated. And checking the protofilament moisture standard according to the principle that the two values are equal, namely: actual full package dry yarn weight (actual full package wet yarn weight) (1-standard moisture content). If the values are not equal, the value of the standard moisture content is modified to obtain a more accurate standard weight for a fully wound wet package. If the ratio of the difference between the average dry yarn package weight calculated in the current round and the standard dry yarn package weight calculated in the full round to the average dry yarn package weight calculated in the current round 1 is 1.5, the standard moisture content is adjusted to 1.5 times the original value.
If the line density is controlled by adjusting the rotating speed of the wire drawing motor, the control process is as follows:
in actual production, the weight of the wet coil 1 taken off by the pick-up head 25 from the winding rotating shaft is 20kg, the system automatically calculates the weight excess proportion to be (20 × 90% -17.5)/17.5 to be 2.857%, and the linear density is greater than the central value by 2.857% according to the weight deviation and linear density deviation equal proportion principle. Because the deviation is positive deviation, the rotating speed of the wire drawing motor is automatically increased, and the rotating speed increase is 2.857% by 10/rotating speed of the wire drawing motor to the linear density influence rule value. And entering the next adjustment execution cycle according to the next full drum weight result until the linear density deviation is within the allowable range (the set central value is +/-0.5% or other standard ranges), and automatically stopping executing the adjustment action.
When the number of the finished product full-package dry yarns corresponding to the control system for realizing the automatic adjustment of the basalt fiber linear density exceeds 100 rolls (other numbers can be set), the linear density average value of the finished product full package and the finished product full package weight average value are automatically calculated, and the ratio of the finished product linear density average value to the standard linear density (2400) and the ratio of the finished product full package weight average value to the dry yarn standard weight (17.5kg) are calculated. And checking the protofilament moisture standard according to the principle that the two values are equal, namely: actual full package dry yarn weight (actual full package wet yarn weight) (1-standard moisture content). If the two values are not equal, deviation correction and checking are carried out on the protofilament moisture standard according to the deviation proportion of the two values, and therefore more accurate standard weight of the full-package dry yarn coil is obtained. If the ratio of the difference between the average dry yarn package weight calculated in the current round and the standard dry yarn package weight calculated in the full round to the average dry yarn package weight calculated in the current round 1 is 1.5, the standard moisture content is adjusted to 1.5 times the original value.
The control method for realizing the automatic adjustment of the linear density of the basalt fiber can automatically monitor the weight of each coil 1 in production so as to monitor the linear density of each coil 1. Meanwhile, the bushing temperature adjusting value or the wire drawing motor rotating speed adjusting value can be automatically calculated according to the linear density of each coil 1, the bushing temperature or the wire drawing motor rotating speed is automatically adjusted, and the linear density of the glass fiber is automatically controlled. After multiple operations, an accurate standard water content value can be obtained, and the standard water content value is modified, so that the linear density of a product produced later is closer to a standard value.
In this embodiment, the influence rule value of the bushing temperature on the line density is calculated by the following method:
s311: under the condition that the rotating speed of the wire drawing motor is not changed and the flow of the bushing plate is not changed, the temperature of the bushing plate is increased or decreased by 1 degree, and the change value of the linear density of the glass fiber after temperature adjustment is recorded. And calculating the change ratio of the linear density of the glass fiber.
S312: step 311 is repeated a plurality of times and the average of the change ratios of the linear density of the glass fiber measured a plurality of times is calculated. And taking the average value of the change proportion of the linear density of the glass fiber measured for many times as the value of the rule of the influence of the bushing temperature on the linear density.
The bushing temperature adjustment value is as follows: the ratio of the actual weight of each full package of dry yarn to the standard weight of the full package of dry yarn/bushing temperature affects the value of the rule on the linear density. If the deviation of the actual weight of each full package of the dry yarn roll and the standard weight of the full package of the dry yarn roll is positive deviation, the controller controls the bushing to cool. If the deviation of the actual weight of each full package of dry yarn from the standard weight of the full package of dry yarn is negative, the controller controls the bushing to increase the temperature.
In practice, glass fibers of various linear densities were tested. An exemplary test was conducted on a glass fiber having a linear density of 2400 to yield a bushing temperature increase or decrease of 1 c and a linear density change of 34.5 for the glass fiber with a 1.44% impact ratio. In the above case, the bushing temperature drop value was 2.857%/1.5% — 1.9 ℃.
In this embodiment, the influence rule value of the rotation speed of the wire drawing motor on the line density is calculated by the following method:
s321: and under the condition that the temperature of the bushing is not changed and the flow of the bushing is not changed, the rotating speed of the wire drawing motor is increased or decreased by 10r/min, and the change value of the linear density of the glass fiber after the rotating speed is adjusted is recorded. And calculating the change ratio of the linear density of the glass fiber.
S322: step 321 is repeated a plurality of times and the average of the change ratios of the linear density of the glass fiber measured a plurality of times is calculated. And taking the average value of the change proportion of the linear density of the glass fiber measured for many times as the regular value of the influence of the rotating speed of the wire drawing motor on the linear density.
The rotating speed adjusting value of the wire drawing motor is as follows: the ratio of the deviation of the actual weight of each full package of dry yarn coil to the standard weight of the full package of dry yarn coil/the rotating speed of the wire drawing motor affects the linear density. The controller controls the drawing motor to accelerate if the deviation of the actual weight of each full package of dry yarn from the standard weight of the full package of dry yarn is a positive deviation. If the deviation of the actual weight of each full package of dry yarn from the standard weight of the full package of dry yarn is a negative deviation, the controller controls the drawing motor to decelerate.
In practice, glass fibers of various linear densities were tested. By way of example, the glass fiber with the linear density of 2400 is tested, and the rotating speed of the wire drawing motor is increased by 10rpm/min, the linear density change value of the glass fiber is 18.5, and the influence ratio is 0.77%. In the above case, the increase of the rotation speed of the drawing motor is 2.857% by 10/0.77% to 37 rpm/min.
In this embodiment, the controller calculates the actual weight of each full package of dry yarn package based on the package's standard moisture content. And when the deviation of the actual weight of each full-package dry yarn coil and the standard weight of the full-package dry yarn coil exceeds a set range or the continuous deviation or the trend deviation exists between the actual weight of each full-package dry yarn coil and the standard weight of the full-package dry yarn coil, the controller controls and adjusts the temperature of the bushing or the rotating speed of the wire drawing motor.
As shown in FIG. 3, if the continuous points (the customizable points) fall on the same side of the centerline, the upper and lower customized internal control limits are not exceeded. These deviations are then persistent deviations. As shown in FIG. 4, if the consecutive points (customizable points) are incremented or decremented (adjustment limit is not reached). Then, these deviations are trend deviations. In practice, the adjustment modes of different errors are artificially defined in a program, for example, upper and lower limits of an internal control are set, and the adjustment mode exceeding the upper and lower limits is automatically adjusted according to the influence rule of temperature on the linear density; when continuous deviation occurs, namely a plurality of continuous numerical values are positioned on the same side of the central line, double temperature adjustment is automatically carried out according to an influence rule, so that subsequent points are positioned on the other side of the central line; the specific adjustment method should be defined with reference to the SPC control chart.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
