Description

  The present invention relates to a combing detaching roller operation setting device, and more particularly, to an independent combing detaching roller operation setting device in which a detaching roller is driven by a motor different from a motor for driving a combing cylinder.

  The comber grips the supplied wrap at a position where the nipper device is retracted, and the tip of the wrap is crushed by a combing cylinder to remove short fibers and the like from the wrap to form a fleece. The fleece is moved toward the detaching roller by the advance of the nipper device. Corresponding to the advance of the fleece, the detaching roller is reversed, the fleece previously taken (the preceding fleece) is moved backward, and the rear end of the fleece and the tip of the newly beaten fleece (following fleece) are connected. Overlapping. Thereafter, the detaching roller rotates forward to take out the fleece from the nipper device, and while joining the succeeding fleece to the preceding fleece, the rear end of the succeeding fleece is rolled by the top comb.

  The detaching roller operation in the comber greatly affects the sliver quality (unevenness) and the mechanical load in the fiber fleece cutting-combing-pecing (bonding) cycle. Conventionally, the rotation of the drive shaft (cylinder shaft) of the combing cylinder is transmitted to the detaching roller by a mechanical mechanism such as a cam or crank, ensuring the operating curve of the detaching roller and adjusting the pecing point according to the spinning conditions. It is common to do it mechanically. And in the trend of productivity improvement (speeding up), the shape of the operation curve is also changing in order to reduce the reverse speed of the preceding fleece and the mechanical load. However, in the configuration in which the rotation of the cylinder shaft is transmitted by a mechanical mechanism to drive the detaching roller, it is said that the operation curve (output curve) is restricted due to the mechanical configuration.

  Accordingly, there has been proposed a comb that is driven by an independent dedicated motor without using a cylinder shaft as a drive source of the detaching roller (see, for example, Patent Document 1). Patent Document 1 proposes a comb that drives a detaching roller (detaching cylinder), a cylinder shaft (circular comb shaft), and a nipper shaft by different driving devices. "The detaching roller driving device is particularly preferably a servo motor. In this case, the position of the starting point A of the detaching operation, the detaching speed (t), the detaching length a or the joining interval l is changed. In order to do this, the adjustment signal can control the energy supply device for the servo motor. " Note that the start point A and the like are shown in FIG. 4 showing a movement stroke of one point on the outer periphery of the detaching roller during one rotation of the cylinder shaft.

  From Patent Document 1, it can be understood that if the detaching roller is driven by a servo motor, the degree of freedom of operation of the detaching roller is increased. However, Patent Document 1 does not describe how to set an appropriate operation curve with respect to the spinning conditions. Only the conditions described in Patent Document 1 provide an appropriate operation curve with respect to the spinning conditions. It is not easy to set. When the detaching roller is driven by a servo motor, an operation curve can be set without being restricted by the machine configuration. However, if the operation curve exceeds the operation performance of the servo motor, the operation curve is used as a result. It is not possible.

  The present invention has been made in view of the above problems, and an object thereof is to provide a combing detaching roller operation setting device capable of easily creating an operating curve of a detaching roller suitable for spinning conditions. There is.

In order to achieve the above object, the invention according to claim 1 is directed to a detaching roller for a combing roller that sets an operating curve of a detaching roller that represents an operating amount from the origin of the detaching roller in correspondence with a rotational angle position of the combing cylinder.

  In the present invention, at least the first to fourth feature points are input by the input means. The first to third auxiliary points may be input by the input unit or may be calculated by the calculation unit based on the input data of the four feature points. When the origin, the four feature points, and the three auxiliary points are determined, the calculation means sets the operation curve so that the operation curve becomes a smooth curve that passes through the eight points of the origin, the four feature points, and the three auxiliary points. To do. Therefore, the operating curve of the detaching roller suitable for the spinning condition can be easily created.

  The invention according to claim 2 is the database according to claim 1, wherein when the set operation curve is suitable for the spinning condition, a database for storing the operation curve and the spinning condition in correspondence with each other is provided. I have. Therefore, according to the present invention, data of operation curves corresponding to different spinning conditions are gradually accumulated in the database. Then, when the spinning condition is input, it is checked whether or not an operation curve suitable for the spinning condition exists in the database. If the operation curve exists, the operation curve setting process is not performed. In addition, the data of the operation curve stored in the database can be used.

  The invention according to claim 3 is the invention according to claim 1 or 2, wherein the set operation curve is differentiated to calculate speed and acceleration, and the speed and acceleration are displayed in a graph based on the calculation result. A display device is provided. In this invention, since it is possible to display the speed and acceleration in a graph on the display device, the operator can easily check the change in the speed and acceleration visually, and when changing the data of the feature point, Data can be changed with reference to changes in speed and acceleration.

  The invention according to claim 4 is the invention according to any one of claims 1 to 3, wherein the set operating curve is differentiated to calculate speed and acceleration, and the calculated acceleration and servo are calculated. Judgment means for judging whether or not the speed and acceleration are appropriate values based on the performance of the motor and outputting a warning signal when the values are inappropriate. Here, the “value with an inappropriate speed” means a value at which the speed cannot be obtained as the performance of the motor. Further, the “value with an inappropriate acceleration” means a value at which an overload is applied to the motor when the detaching roller is driven to achieve the acceleration. Therefore, according to the present invention, it is possible to avoid the set operation curve being used for the test operation (trial spinning) while having an inappropriate value as the speed or acceleration.

  According to the present invention, it is possible to easily create an operating curve of a detaching roller suitable for spinning conditions.

Hereinafter, an embodiment in which the present invention is embodied as a detaching roller operation setting device installed in a comb will be described with reference to FIGS.
In general, a comber includes a working unit provided with eight combing heads. As shown in FIG. 1, the combing head 11 includes a pair of lap rollers 12, a nipper device 14 including a feed roller 13, a combing cylinder 15, and two pairs of front and rear detaching rollers 16 and 17. . The nipper device 14 has a nipper frame 18 that is arranged to be able to swing forward and backward above the combing cylinder 15, and the nipper frame 18 is provided with a bottom nipper 19 at the bottom thereof. A nipper arm 20 is rotatably provided on the nipper frame 18 via a support shaft 18 a, and a top nipper 20 a is fixed to the tip of the nipper arm 20. The top nipper 20a opens and closes at a predetermined timing in synchronization with the forward / backward swinging motion of the nipper frame 18, and cooperates with the bottom nipper 19 to sandwich the lap L. A top comb 21 is attached to the nipper frame 18 so as to perform a predetermined motion in synchronization with the nipper frame 18 in front of the bottom nipper 19.

  A nipper shaft 22 is disposed behind the combing cylinder 15 and below the nipper frame 18 so as to be reciprocally rotatable. A first end portion of a nipper frame driving arm 23 is fixed to the nipper shaft 22 so as to be integrally rotatable, and a rear end portion of the nipper frame 18 is rotatably supported by a second end portion via a support shaft 23a. ing. The nipper frame 18 is configured to swing back and forth so that the tip of the bottom nipper 19 approaches and separates from the detaching rollers 16 and 17 by reciprocating rotation (swinging motion) of the nipper shaft 22. . Rotation of a drive shaft driven by a main motor (not shown) is transmitted to the combing cylinder 15 and the nipper shaft 22 via a mechanical mechanism such as a gear device or a crank, and the nipper device 14 is driven in synchronization with the combing cylinder 15. It has become so.

  On the other hand, both detaching rollers 16 and 17 are driven by a servo motor independent of the main motor. As shown in FIG. 2, shafts 25 and 26 of detaching rollers 16 and 17 are arranged in parallel between gear boxes 24 provided on both sides in the longitudinal direction of the machine base (left and right direction in FIG. 2). Yes. The shafts 25 and 26 are rotatably supported through bearings (not shown) in a state in which both end portions protrude into the gear box 24. Two servomotors 27 and 28 are provided outside the gear box 24 corresponding to the shafts 25 and 26, respectively, with their motor shafts 27 a and 28 a protruding into the gear box 24. A gear train 29 having an idle gear 29a is provided between the shafts 25 and 26 and the motor shafts 27a and 28a. The shafts 25 and 26 have the same rotational speed (the number of rotations of 1: 1) as that of the motor shafts 27a and 28a. Ratio). The servo motors 27 and 28 are synchronously driven in the forward rotation direction and the reverse rotation direction via a servo amplifier (not shown) based on a command from the control device 30.

  The control device 30 performs drive control of motors necessary for driving the combs such as the main motor and the servo motors 27 and 28. The control device 30 includes a CPU 31, a memory 32, an input device 33, and a display device 34. The CPU 31 operates based on program data stored in the memory 32. The input device 33 is used for inputting spinning conditions such as fiber type (fiber length), gelling, nip number, and other data.

  The control device 30 also functions as a detaching roller operation setting device, and the input device 33 is also used to input data necessary for creating a detaching roller operation curve (hereinafter simply referred to as an operation curve). It also functions as input means of the touching roller operation setting device.

  Next, a configuration for the control device 30 to function as a combing detaching roller operation setting device will be described. The CPU 31 sets an operation curve representing the operation amount from the origin of the detaching rollers 16 and 17 in correspondence with the rotational angle position of the combing cylinder 15. In this embodiment, when setting the operation curve, as shown in FIG. 3, a value called an index (INDEX value) obtained by equally dividing the rotation angle position of the combing cylinder 15 (40 in this embodiment) is set on the horizontal axis. A setting screen 36 showing coordinates with the swing angle as the movement amount of the detaching roller as the vertical axis is displayed on the display screen 35 of the display device 34. Then, the operation curve set on the setting screen 36 is displayed.

  In the operation curve shown in FIG. 3, when the swing angle decreases with increasing INDEX value, the detaching rollers 16 and 17 are reversed, and when the swing angle increases with increasing INDEX value, detaching is performed. The rollers 16 and 17 are rotated forward.

  As shown in FIG. 3, the operation curve includes an origin Po, a first feature point S1, a second feature point S2, a third feature point S3, a fourth feature point S4, a first auxiliary point P1, a second auxiliary point P2, and It is constituted by a smooth curve passing through the eight points of the third auxiliary point P3. The origin Po represents the position when the nipper frame 18 is in the last retracted position, and becomes a fixed point regardless of the spinning conditions. The first feature point S1 is a position that becomes a speed change determining factor at the time of preceding fleece reverse, the second feature point S2 is a position that becomes a preceding fleece reverse length determining factor, the third feature point S3 is a position that becomes a pecing speed determining factor, The fourth feature point S4 represents a position serving as a feed length / draft amount determination element. The first auxiliary point P1 is between the first feature point S1 and the second feature point S2, the second auxiliary point is between the second feature point S2 and the third feature point S3, and the third auxiliary point P3 is the third feature point. It is located between the point S3 and the fourth feature point S4. The first auxiliary point P1 is preferably the center point of the first feature point S1 and the second feature point S2, and the second auxiliary point is preferably the center point of the second feature point S2 and the third feature point S3. Further, the third auxiliary point P3 is preferably on the upper side in FIG. 3 than on the straight line between the third feature point S3 and the fourth feature point S4.

  The CPU 31 may also be a calculation means for setting the operation curve to be a smooth curve that passes through the eight points of the origin Po, the four feature points S1, S2, S3, and S4 and the three auxiliary points P1, P2, and P3. Function. The memory 32 stores data of the origin Po (swing angle and INDEX value). Data (swing angle and INDEX value) of the four feature points S 1, S 2, S 3 and S 4 are input by the input device 33. The memory 32 stores initial values (reference values) of the feature points S1, S2, S3, and S4.

  When inputting the feature points S1, S2, S3, S4, initial values of the feature points S1, S2, S3, S4 are displayed on the setting screen 36 of the display screen 35, and fine adjustment in the INDEX direction and the swing angle direction is performed. It is possible. For example, a swing angle adjustment switch and an INDEX adjustment switch are provided, and the feature points S1, S2, S3, and S4 are displayed on the setting screen 36 by finely adjusting the swing angle or INDEX by operating each switch. The position can be changed.

  When the CPU 31 functions as a calculation means for setting an operation curve, the CPU 31 performs the first operation based on the data (swing angle and INDEX value) of the four feature points S1, S2, S3, and S4 input by the input device 33. Data (swing angle and INDEX value) of the auxiliary point P1, the second auxiliary point P2, and the third auxiliary point P3 are respectively calculated. Next, the CPU 31 sets the operating curve of the detaching roller so as to be a smooth curve passing through the eight points of the origin Po, the four feature points S1, S2, S3, S4 and the three auxiliary points P1, P2, P3. To do.

  After setting the operation curve, the CPU 31 calculates the relationship between the INDEX value and the swing angle at every predetermined INDEX interval, for example, every 0.1 INDEX, from the operation curve, and stores it as a swing angle table for each 0.1 INDEX. 32. The CPU 31 calculates the speed for every 0.1 INDEX based on the data of the swing angle table and stores it in the memory 32 as a speed table for every 0.1 INDEX. Further, the CPU 31 differentiates the speed data for every 0.1 INDEX based on the data of the speed table, calculates the acceleration for every 0.1 INDEX, and stores it in the memory 32 as an acceleration table for every 0.1 INDEX.

  The CPU 31 can display changes in the swing angle, speed, and acceleration in each INDEX on the display screen 35 of the display device 34 based on the swing angle table, speed table, and acceleration table stored in the memory 32, respectively. It has become. Further, the CPU 31 determines whether the speed and acceleration are appropriate values based on the speed of the speed table and the acceleration of the acceleration table and the performance of the servo motors 27 and 28 that drive the detaching rollers 16 and 17. When the value is inappropriate, a warning signal is output. That is, the CPU 31 determines whether or not the speed and acceleration are appropriate values, and also functions as a determination unit that outputs a warning signal when the values are inappropriate. When a warning signal is output, warning means such as a warning lamp (not shown) is activated. The “value with an inappropriate speed” means a value at which the speed cannot be obtained as the performance of the motor. The “value with an inappropriate acceleration” means a value at which an overload is applied to the servo motors 27 and 28 when the detaching rollers 16 and 17 are driven so as to achieve the acceleration.

  The operation curve set by the CPU 31 is not used as it is as the operation curve for the actual operation of the comber, but the test operation (trial spinning) of the comber is performed using the operation curve, and good results are obtained by the trial spinning. When it is obtained, the operation curve data is stored in the database area provided in the memory 32 together with the spinning conditions.

  When operating the comber, the control device 30 determines whether or not an operation curve corresponding to the spinning condition input by the input device 33 is stored in the memory 32, and if it is stored, the operation curve. Is used to control the driving of the detaching rollers 16 and 17. On the other hand, if the operation curve corresponding to the spinning condition is not stored in the memory 32, it is notified that the operation curve needs to be set.

Next, the operation of the apparatus configured as described above will be described.
When the comb is manufactured at the factory, the memory 32 does not store an operating curve or stores a temporary operating curve. Therefore, when operating the comb for the first time, first set the operating curve. There is a need to do. When setting the operation curve, after selecting a state in which the control device 30 functions as the operation curve setting device, the input device 33 causes the spinning conditions such as fiber type (fiber length), gelling, nip number, and the like, Data of the first feature point S1, the second feature point S2, the third feature point S3, and the fourth feature point S4 are input.

  When the spinning conditions and the data of the four feature points S1, S2, S3, S4 are input, the CPU 31 calculates the three auxiliary points P1, P2, P3, and then the origin Po, the four feature points S1, S2. , S3, S4 and the three auxiliary points P1, P2, P3, the operation curve is set to be a smooth curve passing through the eight points. After setting the operation curve, the CPU 31 calculates the speed and acceleration in each INDEX, determines whether or not the speed and acceleration are appropriate values, and outputs a warning signal when the values are inappropriate. When the operator confirms that the warning signal is output by the warning means, the operator changes at least one of the data of the feature points S1, S2, S3, S4. If a warning signal is not output after a new operation curve is set, the operation curve is stored in the memory 32 and then trial spinning is performed. When a good result is obtained by trial spinning, the data of the operation curve is stored in the memory 32 together with the spinning conditions. The memory 32 also stores a swing angle table, a speed table, and an acceleration table.

  Even if operation curve data is stored together with the spinning condition in the memory 32, if the operation curve data corresponding to the spinning condition input by the input device 33 is not stored, the spinning condition corresponds to the spinning condition. After the operation curve to be set is set, the comber is operated.

  During operation of the comber, the CPU 31 controls the main motor and the like, and controls the servo motors 27 and 28 using the operation curve stored in the memory 32. Specifically, the CPU 31 controls the servo motors 27 and 28 using the operation curve so that the swing angle corresponding to the INDEX at the time of control is obtained from the swing angle table stored in the memory 32. Note that the CPU 31 outputs a warning signal and stops the operation when the acceleration data of the operation curve is an inappropriate value when the rotation speed of the servo motors 27 and 28 is changed during the operation of the comber.

According to this embodiment, the following effects can be obtained.
(1) The detaching roller operation setting device sets an operation curve representing the operation amount from the origin of the detaching rollers 16 and 17 in correspondence with the rotational angle position of the combing cylinder. The detaching roller operation setting device is set so that the operation curve is a smooth curve passing through the eight points of the origin Po, the four feature points S1, S2, S3, S4 and the three auxiliary points P1, P2, P3. Computing means (CPU 31) for performing the operation, and input means (input device 33) for inputting at least the first feature point, the second feature point, the third feature point, and the fourth feature point. The first feature point S1 is a point that becomes a speed change determining factor when the preceding fleece moves backward, and the second feature point S2 is a point that becomes a preceding fleece retracting length determining factor. The third feature point is a point that becomes a piecing speed determining factor, and the fourth feature point is a point that becomes a sending length / draft amount determining factor. The first auxiliary point is a point between the first feature point S1 and the second feature point S2, the second auxiliary point P2 is a point between the second feature point S2 and the third feature point S3, and the third auxiliary point P3. Is a point between the third feature point S3 and the fourth feature point S4. Therefore, the operator can easily create an operation curve suitable for the spinning conditions.

  (2) The CPU 31 calculates three auxiliary points P1, P2, and P3 based on the four feature points S1, S2, S3, and S4 input by the input device 33. Therefore, the operator can more easily create an operation curve suitable for the spinning conditions without inputting the three auxiliary points P1, P2, and P3.

  (3) The detaching roller operation setting device includes a database that stores the operation curve and the spinning condition in association with each other when the set operation curve is suitable for the spinning condition. Therefore, when the spinning condition is input, it is checked whether or not an operation curve suitable for the spinning condition exists in the database. If the operation curve exists, the operation curve setting process is not performed. In addition, the operating curve stored in the database can be used.

  (4) The detaching roller operation setting device includes a display device 34 that differentiates the set operation curve to calculate the speed and acceleration, and displays the speed and acceleration in a graph based on the calculation result. Accordingly, by displaying the speed and acceleration in a graph on the display screen 35 of the display device 34, the operator can easily check the change in the speed and acceleration visually, and when changing data such as the feature point S1. In addition, data can be changed with reference to changes in speed and acceleration.

  (5) The detaching roller operation setting device calculates the speed (one-time differentiation) and acceleration (two-time differentiation) by differentiating the set operation curve, and the calculated speed and acceleration and the servo motors 27 and 28 are calculated. And determining means for determining whether or not the speed and acceleration are appropriate values, and outputting a warning signal when the values are inappropriate. Therefore, it is possible to avoid the set operation curve being used for the test operation (trial spinning) while having inappropriate values as the speed and acceleration.

  (6) If the acceleration data of the operation curve is an inappropriate value during the operation of the comb, the CPU 31 outputs a warning signal and stops the operation. Therefore, even when an operation curve containing an inappropriate value of acceleration data is stored in the memory 32 by mistake when setting the operation curve, it is automatically determined whether the operation is possible, and the servo motors 27 and 28 are overloaded. Driving in a state can be avoided.

  (7) When creating an operation curve, a setting screen 36 showing coordinates with the INDEX value as the horizontal axis and the swing angle as the operation amount of the detaching rollers 16 and 17 as the vertical axis is the display screen 35 of the display device 34. The operator can confirm the adjustment of the shape of the operation curve and the adjustment of the piecing point on the panel.

  (8) The input of the feature points S1, S2, S3, S4 is performed by fine adjustment of the initial value displayed on the setting screen 36, instead of the operator inputting those data as completely new data. . Therefore, input of the feature points S1, S2, S3, S4 is facilitated.

The embodiment is not limited to the above, and may be embodied as follows, for example.
○ The detaching roller operation setting device may be a device independent of the comber. For example, the operation curve may be set using a dedicated detaching roller operation setting device or a personal computer installed with a program for setting an operation curve.

The operation curve and spinning condition data stored as a database in the memory 32 may be transferred to the control device 30 of another comber using an external memory or communication.
As an operation curve, different operation curves may be stored in the database for the case where spinning is performed with emphasis on quality and when the spinning is performed with emphasis on productivity, even if the fiber types of the spinning conditions are the same. In this case, an optimal pattern can be selected according to the purpose.

○ When the comber is equipped with a sliver quality monitor, the quality information and the operation curve may be associated with each other in cooperation with the sliver quality monitor.
The feature points S1, S2, S3, S4 may be directly input by the input device 33 without providing the initial values of the feature points S1, S2, S3, S4.

○ It is not necessary to provide a database for storing the set proper operation curve and spinning conditions in association with each other.
○ It is not necessary to provide a graph display function for speed and acceleration.

  ○ It is not necessary to provide a judgment means for outputting a warning signal when the speed and acceleration are inappropriate values. Further, it may be determined whether or not the acceleration is an appropriate value, and a warning signal may be output only when the acceleration is an inappropriate value.

  ○ The operation curve is not limited to the shape driven so that the detaching rollers 16 and 17 are reversed from the state where the INDEX value is 0, but is reversed after the detaching rollers 16 and 17 are normally rotated. It may be a driven shape. In that case, the value of the swing angle of the first feature point S1 becomes positive, and the preceding fleece does not start retreating immediately after the combing cylinder 15 is rotated from the origin, but retreats after it has advanced. . Therefore, the feature point S1 has a function as a preceding fleece reverse start point determining element in addition to a function as a speed change determining element when the preceding fleece moves backward.

  The CPU 31 may calculate the swing angle data, the speed data, and the acceleration data at an interval smaller than the 0.1 INDEX value interval or at an interval larger than the 0.1 INDEX value interval.

  A specific one on the surface of the detaching roller without using the INDEX value as the horizontal axis of the coordinate indicating the operation curve, or using the rotation angle from the origin of the combing cylinder 15 or using the swing angle as the vertical axis. The movement distance of the point (reference point) may be used.

  The gear train 29 that transmits the rotation of the motor shafts 27a and 28a to the shafts 25 and 26 does not necessarily include the idle gear 29a, and the gears fixed to the motor shafts 27a and 28a are fixed to the shafts 25 and 26. The structure which meshes | engages directly with a gear may be sufficient.

  Each shaft 25, 26 may be driven by one servo motor 27, 28 from one end thereof, and the other shaft may be rotated integrally with the other end via a gear train. Moreover, it is good also as a structure which drives both shafts 25 and 26 with one servomotor.

  The motor shafts 27a, 28a and the shafts 25, 26 are not limited to a rotation speed ratio of 1: 1, and even if the rotation speeds of the motor shafts 27a, 28a are higher than the rotation speeds of the shafts 25, 26, the motor shafts 27a, 28a May be slower than the rotational speed of the shafts 25 and 26.

  ○ The movement curve created as a smooth curve passing through the eight points of the origin Po, the four feature points S1, S2, S3, S4 and the three auxiliary points P1, P2, P3 is shifted in the + or-direction of the INDEX value. It may be possible to adjust the piecing point.
