German Patent Application Publication No. 10037513 (Obj. 2812) German Patent Application Publication No. 102014469

  The object of the present invention is to eliminate the drawbacks.

  In order to solve the above problems, the method according to the present invention adjusts the spinning program according to a predetermined application purpose in a predetermined period section after spindle start or a period section starting with spindle start. The spinning program in order to obtain a constant or changed stretch in the sliver and a constant or changed twist in the formed yarn or thread or decorative yarn, depending on the predetermined characteristic value. Depending on the current production conditions, temporarily twisting and / or drawing the sliver or thread (threads) in order to achieve high operational reliability, in particular to achieve continuous production. The adjustment is made different from the characteristic value of the standard spinning program.

  With the method according to the present invention, a predetermined spinning program can be changed during winding on a yarn support (bobbin or spinning tube), that is, at any stage during spinning, so that yarn breakage and eventually machine stoppage can be achieved. Can be avoided and a certain yarn quality can be achieved. In particular, the drawing (draft) and twist (twist) of the yarn can be changed depending on the predetermined conditions at the start of the machine.

  As shown in FIG. 1, the yarn 11 is formed between a drawing mechanism composed of drawing cylinders 140, 160 and 180 and a spindle 128 in the spinning section of the spinning machine. The drawing cylinders 140, 160, 180 may be driven by each motor 14 (and 16 and 18 in FIG. 3), or a transmission 14A is disposed between the two drawing cylinders 140, 160; Therefore, only one motor 14 is required to drive both drawing cylinders. The yarn package 130 on the spindle 128 is surrounded by a ring traveler unit 72 on the ring frame 70, and the ring frame is moved up and down during the spinning process, that is, spinning, as shown by the double arrows. In the ring spinning machine, the spindle 128 is driven by a belt pulley 126 via a belt 126A. The belt pulley is attached to the spindle shaft 124, and the spindle shaft itself is driven by the spindle motor 12. It has become. Usually, a transmission device is arranged between the spindle motor 12 and the spindle shaft 14. Each spindle may have its own motor, or one motor may be provided for each group of spindles.

  The invention is also used in principle for other types of spinning machines where the twisting and drawing of the yarn can be changed by the action of different members.

  The transition (elapsed) of the spindle speed N128 as well as the stroke H70 of the ring frame 70 is shown over one cup stroke, ie over one cycle during spinning of the yarn package. Before the start of the spindle motor 12, the ring frame 70 is moved, in which case the stroke of the ring frame 70 is first rapidly increased. Nearly simultaneously with the subsequent downward movement of the ring frame 70, the spindle motor 12 is connected, i.e. switched on, and the spindle 128 is strongly accelerated, so that the spindle speed is increased very rapidly. In the area indicated by the symbol A after the start of the spindle (periodic section), the rotational speed program is advantageously adjusted or interfered with in accordance with the specific application purpose, so that a constant stretch and formation within the sliver is achieved. The standard spinning program that produces a constant twist in the yarn (thread) is varied. In producing a yarn with constant twisting and drawing, it is necessary to drive the spindle 128 and the drawing cylinders 140, 160, 180 unchanged, that is, at a constant rotation speed ratio. However, as indicated by the reference signs A and B in FIG. 2, changes over a short time segment of twisting and drawing of the yarn 11 are made for quality assurance at machine start-up and before machine stop. The quality assurance before the machine stops is described in the second specification. For example, in order to reduce yarn breakage in a thin yarn, the strength of the yarn is increased in a short time in the period section A of FIG. 2, and the stretching of the sliver supplied to the spinning machine is reduced. Conversely, it is advantageous to weaken the yarn at the beginning and end of the spinning process, for example during the treatment of chemical fibers, which is done by increasing the stretch of the formed yarn and decreasing the twist. The change in the characteristics of the yarn at the start and end of the spinning process occurs when the start and end portions of the yarn 11 of the yarn package 130 are separated during the subsequent rewinding process in the subsequent processing (post processing) of the yarn. It does not work inconveniently. Usually, the start and end portions of the yarn wound on the yarn package 1 are separated automatically in the rewinding process. By fixing the thin yarn constriction in the period section A, a stable ballooning essential for the spinning process is quickly achieved after the spinning machine is connected. For thick yarns, it is advantageous to weaken in relation to the yarn cross section or twist. In this case, the spinning machine is started at a low speed, and a stable spinning state is achieved from the beginning of spinning. Can do. By such means, the drive components of the spinning machine can be made light, and thus a high acceleration capacity at the start of the spinning machine is achieved.

  As indicated by region (periodic division) B in FIG. 2, the change in yarn characteristics is advantageous even at the final stage of the spinning process. During a sudden drop of the speed characteristic curve N128 during the winding end process in the period section or region B, the ring frame 70 is moved rapidly downward depending on the stroke function H70 so as to fix the thread to the base of the spindle 128. It has become. In order to subsequently remove the yarn package 130 from the spindle 128, the yarn twist is advantageously reduced or the sliver draw within the draw mechanism is increased. In some cases, conversely, it is also advantageous to reduce stretching and increase yarn twist, thereby ensuring that the yarn is clamped to the base of the spindle 128 upon removal of the package 130.

  Preferably, frequency inverters 22, 24, 28 are used for supplying current to the spindle motor 12, the first stretching motor 14, and optionally the second stretching motor 16, and the third stretching motor 18. It is. When both the drawing cylinders 140 and 160 are driven by the only motor 14, a subsequent transmission 16A is arranged. That is, a transmission device is provided between the stretching cylinders 140 and 160 and the motor 14. However, each individual drawing cylinder 140, 160 may have its own motor 14 or 16, each motor having its own transmission, and two different power supplies for supplying current to each motor. Frequency inverters 24A and 24B are provided. In the following, although only one inverter will be described for both motors, one inverter means one inverter. The stretching cylinders 140 and 160 have a constant rotation speed ratio when the transmission device 16A is arranged. In this case, the preliminary stretching (pre-stretching or pre-stretching) between both the cylinders is performed by a gear. Adjusted by exchange or exchange of one transmission element. In the adjustment of the drawing, the rotation ratio between the drawing cylinders 140, 160 arranged on the front side (inlet side) and the outlet side cylinder 180 of the drawing mechanism is preferably changed on the outlet side. For this purpose, the rotation speed is changed in both the drawing cylinders 140 and 160 arranged on the front side and the drawing cylinder 180 arranged on the rear side, or only on the drawing cylinders 140 and 160 arranged on the front side or on the rear side. The number of revolutions is changed only by the stretching cylinder 180 arranged in the cylinder. The rotation speed inverters 22 and 24 (24A and 24B) include a control unit 32, 34, or 38. The control unit sends a signal from the control device 40 and the sensor 122 arranged in a higher order via lines (conductive wires) L1 and L2. Receive and process. The sensor 122 is arranged in the transmitter 120 on the spindle shaft 124 and is preferably formed as a pole wheel. In the illustrated embodiment, the control device includes an input module 41, an operation program module 42, a twist module 44 and a stretching module 46. The spinning machine operation program is input by an operator (operator) through the input module and the memory 41 and processed by the computer 48. The operation program may be stored in the operation program module 42, that is, the data obtained depending on the characteristic value of the number of revolutions is processed, and the frequency inverter for the spindle is directly used as a control value via the line L1A. It may be formed so as to be able to input into the 22 control units 32. The control of the frequency inverters 24, 28 is on the one hand dependent on the signal produced by a sensor that cooperates with the transmitter 120. The signal arrives at the control unit 34 or 38 via the control line L2. On the other hand, the control parameters from the computer 48 are supplied to the frequency inverters 24 and 28 using the electrical communication line 60 via the line L1B. In this case, the control parameters are the drawing module 46 and the twisting module. 44 is formed on the basis of 44 outputs and is preferably varied in the period sections A and B. The control parameters reach the frequency inverters 24, 28 via the control units 34, 38 in parallel with the signal F of the sensor 122 and are processed to form control signals for the stretching motors 14, 16, 18; Is multiplied by each other.

  In another embodiment, it is possible to omit the transmitter 120 and the control input unit L2 for the signal units 34 and 38 of the frequency inverters 24 and 26, and to control the frequency inverter only by the computer of the control device 40. In this case, all control data for the frequency inverters 22, 24, 28 are supplied from the control device 40 to the frequency inverter via the electrical communication line 60. In this case, the data provided from the operating program module 42 for the spindle speed transition N128 is processed by the computer 48 and simultaneously from the calculated data for the sliver extension from the extension module 46 and the twist module 44. The data for the twist of the yarn is changed as needed. The data given to the input module 41 by the operator includes, in particular, the spindle speed transition N128 over a predetermined time, the total length of the thread wound on the thread support, and the length between the period sections A and B. And includes data for the standard drawing and standard twisting of the yarn to be produced and the movement of the ring frame 70 when the drawing or twisting is defined differently from the standard value. The computer program for processing the data may be stored in, for example, the input module and the memory 41, whereas the current spinning program data may be stored in the modules 42 to 46.

  Advantageously, but not essential, when changing the stretching and twisting in the sliver or yarn, the original speed program for the spindle 128, i.e. the speed transition N128, is maintained unchanged and the stretching and twisting is maintained. The change is made by adjusting the rotational speeds N4, N6 and N8 of the drawing cylinders 140, 160 and 180. In a simple embodiment, it is possible to increase the stretching by changing only the rotation speed N8 of the third stretching cylinder for the stretching change, for example by increasing the rotation speed by a predetermined factor. If it is desired to change the twist of the yarn, for example to increase it, the drawing mechanism motor is decelerated to a predetermined value and is rotated at approximately 83% of the normal speed, for example to increase the twist by approximately 20%.

  In connection with the yarn parameters, the operation of the control device 40 is performed as follows. Prior to starting the spinning machine 10 for spinning with newly supplied material, the operator must run an operating program such as the rotational speed curve N128 shown in FIG. 2, stretch values (stretch cylinders 140 and 160 or 160 and Characteristic values for the above-mentioned differences from the standard spinning program as well as pre-drawing or main drawing to 180) are incorporated into the input module of the spinning machine to draw and / or twist the yarn to be produced. Adjust. For example, at the start, the stretch is increased by 20% or the yarn twist is reduced. Advantageously, the range of change in stretching and twisting is between 50% and 200% of the nominal value of stretching and twisting. It is also possible to produce a decorative twisted yarn, in which case the stretching change is applied to a standard operating program in which the spindle shaft 124 is rotated at a constant rotational speed relative to the rotational speed of the stretching cylinders 140, 160, 180. Superimposed.

  The controller 40 operates as follows for the drive components for the various drawing cylinders in processing the data read using the various modules or embedded software, i.e., the transmitter on the shaft 124. The signal of the frequency F of 120 is converted into a target frequency in the control units 34 and 38, and the target frequency corresponds to a predetermined number of rotations of the stretching mechanism motors 14 to 18, which are different from each other in this case. This is done in particular by computer processing of the value of the frequency F, the values of the pre-drawing factors A1, A2, the factors V1, V2 for the change in drawing, the main drawing factor B1 and the factor D for the change in twist. Is called.

  The operation program, that is, the rotation speed transition (rotational speed characteristic curve) 128 shown in FIG. 2 is continuously transmitted to the control unit 32 of the frequency inverter 22 through the operation module and the data line L1A. At the same time, a new reference value for the rotational speed characteristic curve 128 is sent to the control unit 32, whereby the frequency inverter 22 supplies a current of a corresponding frequency to the spindle motor 12, so that the spindle motor is shown in FIG. The spindle rotates at a rotational speed corresponding to the spindle rotational speed N128. The rotational movement or rotational speed of the spindle shaft 124 is detected by the sensor 122 and the transmitter 120 (for example, a magnetic pole wheel provided on the spindle shaft) to generate a signal of the actual rotational speed of the spindle shaft 124 and thus the spindle 128. It is like that. The signal is sent to the control input units of the control units 34 and 38 of the two frequency inverters 24 and 28 via the signal line L2 at short time intervals, and the stretching mechanism motors 14, 16, and 18 are driven by the frequency inverters. It comes to control. The signal having the frequency F from the transmitter 120 is converted into a predetermined target value by the control units 34 and 38 as follows, and the target value corresponds to the rotational speeds of the stretching mechanism motors 14, 16, and 18 which are different from each other. ing.

  I) Standard spinning operation with constant stretching and constant twist. The rotation speed N4 of the first stretching mechanism motor 14 is obtained by the function FxA1, that is, obtained as a product of the function (x means x). In this case, A1 is stored in the control unit 34. A pre-stretch value of 1. When a second stretching mechanism motor is provided for the second stretching cylinder 160, the rotational speed N6 of the motor is obtained by the function FxA2, in which case A2 is the second preliminary stretching coefficient. . The rotation speed N8 of the third stretching mechanism motor 180 is obtained by the function FxB. In this case, B1 is a main stretching coefficient, and the main stretching coefficient is stored in the control unit 38 of the frequency inverter. The preliminary drawing factors A1 and A2 and the main drawing factor B1 are input into the input module 41 as a function by the operator and are continuously transmitted from the computer 48 to both frequency inverters 24 and 28 via line L1B.

When processing depending on the characteristic value, the yarn is formed with a constant twist and a constant stretch, because the rotational speed of the spindle shaft 124 is the rotation of the motors 14, 16, 18 for the stretching mechanism. This is because it is always proportional to the number. In order to obtain a desired yarn twist at the characteristic values A1, A2, B1 (first pre-drawing factor, second pre-drawing factor and main drawing factor), the characteristic values A1, A2, B1 are input modules. Selection of the data input value from 41 is increased or decreased by the same factor to produce a small or large yarn twist.
II) Spinning operation with altered or adjusted stretching. For example, when only the stretching change is performed in the period sections A and B shown in FIG. 2, the target rotational speeds N4, N6, and N8 of the stretching mechanism motors 14, 16, and 18 are set as additional coefficients for the stretching change. It is specified based on the processing by.

  The number of rotations of the first stretching mechanism motor 14 is determined by the function FxA1xV1, and in this case, V1 is a first stretching change coefficient. The rotation speed N6 of the second stretching mechanism motor 16 is obtained by the function FxA2xV1, whereas the rotation speed N8 of the third stretching mechanism motor 18 is obtained by the function FxBxV2, and in this case V2 is due to the stretching change. Of the second stretching change coefficient. Only one of the characteristic values V1 and V2 is changed from 1 in order to achieve the drawing change, that is, to make it different from the standard spinning operation, that is, to obtain a spinning operation different from the standard spinning operation. It's okay. For example, when it is desired to increase the stretching, the third stretching mechanism motor 18 is driven at a high speed by defining a characteristic value of V2> 1. The coefficients V1 and V2 for the stretching changes are transmitted from the stretching module 46 to the various addresses of the frequency inverters 24 and 26 for the stretching cylinder via the electrical communication line 60 as shown in FIG. . In the control units 34 and 38 of the frequency inverters 24 and 28, the function, for example, FxA1xV1 is formed to define the rotational speed N4. In another embodiment, the target values N4, N6, N8 can be formed only by the computer 48 of the control device 40.

  III) Spinning operation with altered or adjusted twist. In the case of changing the twist with respect to the standard spinning operation in the period sections A and B in FIG. 2, the rotation speed of the drawing cylinder differs from the standard spinning operation and is defined as follows.

  The rotation speed N4 of the first stretching mechanism motor 14 is obtained by the function FxA1xD using the twist coefficient D in order to obtain a twist change. Similarly, another rotational speed is calculated. The rotational speed for the second stretching mechanism motor 16 of the second stretching mechanism is obtained by the function N6 = FxA2xD, and similarly, the rotational speed N8 for the third stretching mechanism motor is the function FxBxD. Choosing a value of D> 1 causes the drawing cylinder to rotate at a higher speed compared to the spindle shaft 124, so that the yarn twist is reduced at constant drawing. The coefficient D for the twist change is transmitted using the electrical communication line 60 via the twist module 44 of the control device 40.

  The formation of the control values for the frequency inverters of the stretching mechanisms 24, 28 may take place in the computer 48 of the control device 40 instead of the control devices 34, 38, for which purpose the signal F of the sensor 122 is represented by the line L2. To the control device 40 and using the characteristic values from the operation program module 42, the stretching module 46 and the twisting module 44 in the computer, for example, a value for the frequency F, the first preliminary stretching coefficient A1. Is multiplied by the value for, the first factor V1 for the stretching change, the factor D for the twist change, etc.

  IV) A spinning operation performed by adjusting or changing stretching and twisting. When the stretching change and the twisting change occur simultaneously, the rotation speed for the stretching mechanism motors 14 and 18 is defined in the frequency inverters 24 and 28 or the controller 40 as follows. The rotation speed of the first stretching mechanism motor 14 is obtained by the function FxA1xDxV1, while the rotation speed N8 of the third stretching mechanism motor is calculated as a product of the function FxBxDxV2.

  As is generally known, a plurality of motors having the same frequency are usually connected to one frequency inverter (frequency converter), and a long spinning machine has a plurality of motors in the same drawing cylinder. Yes.
