Definitions
- the invention relates to a method for controlling the rotary drive of a turntable carrying at least one winding spindle of a winding machine for a continuously starting thread, which is further provided with a traversing device and a contact roller arranged upstream of the turntable in the thread path, in which the contact roller by controlling the rotary drive of the turntable is kept in constant circumferential contact with the coil package, which increases in diameter during the coil travel and is carried by the or one of the two coil spindles.
- EP 0 374 536 B1 describes such a method for controlling the rotary drive of a dishwashing machine, in which the stroke of the slightly movably mounted contact roller is queried via a sensor and the rotary drive is controlled in such a way that peripheral contact between the contact roller and the coil pack is ensured.
- the method known from the cited document presents itself as a closed control loop.
- Such a closed control loop tends to oscillate particularly under the influence of disturbance variables. Disturbances are e.g. B. Vibrations of the bobbin spindle, non-round bobbin packs and bobbin packs with mirror symptoms, fluctuations in the contact force of the contact roller, etc. Safe operation and good bobbin build-up cannot be achieved with the winding machine with such a control circuit.
- the invention has for its object to provide a method for controlling the rotary drive of a dishwasher, which acts reliably and in a simple manner and does not tend to vibrate.
- this object is achieved by calculating the respective diameter of the bobbin pack by forming the quotient of the product of the rotational speed (speed) of the contact roller and the diameter of the contact roller to the rotational speed (rotational speed) of the bobbin carrying the bobbin, determining the angular position of the bobbin carrying the bobbin Spool spindle on its turning circle, in which the circumference of the bobbin pack is in peripheral contact with the contact roller, from the calculated respective diameter of the bobbin pack, and control of the rotary drive of the turntable in such a way that the bobbin winder carrying the bobbin pack assumes the determined angular position on its turning circle.
- a preferred exemplary embodiment is distinguished in that the respective speed of rotation of the contact roller is detected by querying a corresponding sensor.
- the rotational speed of the bobbin spindle is also preferably determined by querying a sensor that detects it, but if a synchronous motor is used to drive the bobbin spindle, the signal that drives the synchronous motor can also be used directly.
- a preferred embodiment is characterized in that the respective angular position of the winding spindle carrying the bobbin package on its rotating circle, in which the circumference of the bobbin package is in circumferential contact with the contact roller, is read from a table in which the
- Angle / diameter relationship is stored. Alternatively, however, an exact calculation can also be carried out using the geometric relationship.
- the contact roller be held in a loaded rocker, the load acting on the rocker and determining the contact pressure of the contact roller on the coil package from the load Angular position of the winding spindle and thus depends on the respective diameter of the package on the winding spindle. It is preferred that the force acting on the rocker is dependent on its angular position and the angular position of the coil spindle is adjusted in accordance with the respective diameter of the coil package in such a way that the contact force of the contact roller on the coil package assumes a predetermined value.
- FIG. 1 shows the schematic structure of a winding machine
- Figure 2 is a schematic representation of the method according to the invention in its basic form for another Aufsp lmaschine.
- FIGS. 4 to 10 symbolically show the program sequences for various exemplary embodiments.
- Figure 11 shows the angular position of the turntable as
- FIG. 12 shows an enlarged section from FIG. 11 as well as those actually run through
- the winding machine shown in FIG. 1 has a turntable 10 which carries two winding spindles 14. Above the turntable 10 is an upstream one in the thread path
- Contact roller 12 rotatably attached to its own axis.
- the contact roller 12 is in circumferential contact with the bobbin pack 16 which is formed on the respectively operated winding spindle 14.
- a traversing device 3 attached above the contact roller 12 to a support arm 7 lays the thread 5 perpendicular to the rotating movement of the rotating winding spindle 14.
- a housing 1 of the winder takes this Support arm 7, the contact roller 12 and the turntable 10.
- the contact roller 12 is stationary, that is to say not radially movable.
- the setpoint signal of the setpoint setter 21 is further transmitted to a computer 27, which as a further input signal via a sensor 29 is an actual rotation speed of the
- Coil spindle 14 receives the corresponding signal.
- the computer 27 outputs an address signal to a table 31, from which the value read out is input into a controller 33 which controls the motor 35 which drives the turntable 10.
- the turntable 10 is rotated clockwise according to FIG. 1, counterclockwise according to FIG.
- the rotary drive of the turntable 10 is controlled in such a way that the rotational speed nT of the contact roller and the rotational speed nS of the winding spindle 14 are continuously determined. Since the product of the diameter DS and the rotational speed of the winding spindle nS must always be the same as the product of the rotational speed of the contact roller nT and the diameter of the contact roller d because of the contact, the following applies:
- the angle ⁇ is calculated at which the contact roller 12 bears against the circumference of the coil pack 16.
- this calculation can be carried out on the basis of the geometric relationship shown in FIG. 11, but preferably - as shown in FIG. 2 - via table 31, in which the respective angular positions of the winding spindle 14 depend on the particular one Diameter of the coil pack 16 are entered.
- the drive of the turntable 10 can also be controlled so that it is rotated by a fixed angular amount during the coil travel. In this case, the turntable 10 continues to rotate when the respective diameter of the coil package 16 has increased by an amount that requires such further rotation of the turntable to maintain the desired circumferential contact with the contact roller.
- the contact roller 12 can also be held in a loaded rocker 18, as shown in FIGS. 3a and 3b, the load of the rocker 18 determining the contact pressure of the contact roller on the coil package 16.
- the load acting on the rocker 18 can be adjusted, for example by the provision of a spring 20 acting on the rocker or by the use of a pneumatically operated cylinder, as a function of the respective diameter of the bobbin pack 16 seated on the winding spindle 14.
- the position of the contact roller 12 is not detected and is therefore not used for controlling the angular position a of the bobbin spindle 14 carrying the bobbin pack 16.
- FIGS. 3a and 3b show the spring 20 which is tensioned to different extents by the displacement of the contact roller 12.
- the angular position of the winding spindle 14 is set as a function of the respective diameter of the winding package 16 such that the contact roller assumes a position in which the spring 20 generates a corresponding force via the rocker 18.
- FIG 4 shows symbolically the control of a winding process.
- the control works intermittently.
- the consecutive number of the measure is denoted by x.
- the control unit is programmed so that a switching operation is carried out when the diameter DS of the coil 16 has reached or exceeded a predetermined value.
- the predetermined diameter increases from cycle to cycle by 0.1 mm. This increment is entered into the device.
- the essential dimensions of the machine and the parameters of the special winding process are also entered, namely the diameter d of the contact roller, the effective diameter A of the turntable (this is twice the distance between the axis of a winding spindle 14 and the axis of the turntable 10).
- the speed nS of the coil 16 is measured with the sensor 29 during the winding process.
- the speed nT is also the Contact roller 12 measured with a sensor 36.
- the instantaneous diameter DS of the coil 16 is calculated from the two speeds and the diameter d of the contact roller 12.
- D (x) is the diameter which is assigned to the cycle with the serial number x.
- the instantaneous diameter DS calculated from the measured speed nS is compared with the predetermined diameter D (x). If D (x) has not yet been reached, the
- the instantaneous diameter DS is equal to or a little larger than D (x)
- the angle a (x) belonging to the current diameter DS is calculated using the formula given in FIG. Then the difference ⁇ a (x) between the angle ⁇ (x) and the previously reached angle ⁇ (x - 1) is determined.
- the difference angle ⁇ ⁇ (x) is multiplied by the reduction i. This results in the angle through which the motor 35 must rotate.
- the difference angle is transmitted to the control unit 35a of the engine 35, which makes the calculated change. This process is repeated until the final diameter Dmax is reached.
- the winding process illustrated by FIG. 5 is characterized by two differences compared to the process according to FIG. 4: it is assumed that the speed nT of the contact roller 12 is constant. The constant speed nT is also entered into the device. A sensor for measuring nT is not provided. The second difference is that a table is entered which individually assigns a diameter D (x) to each individual cycle x. The differences between the diameters successive bars can be of different sizes. This can e.g. B. may be useful if an extended time interval is required to replace a full spool with an empty tube.
- the exemplary embodiment according to FIG. 6 differs from the exemplary embodiment illustrated in FIG. 5 in that in addition to the diameters, the corresponding angles ⁇ (x) are also entered in the form of a table. This is advantageous if a controller is used which cannot perform an arithmetic calculation according to the formula given in FIG. 11.
- control unit receives the instruction to change the angular position a from step to step by a constant differential angle.
- the associated diameters are calculated using the formula given in FIG. 11 and entered in the form of a table.
- the motor 35 which is coupled directly to the shaft of the turntable (10) without an intermediate gear, is equipped with an incremental encoder which is not shown separately in the drawing. Each time the motor 35 rotates, it sends a specific number I of pulses to a control unit belonging to the motor (example: 10,000 pulses per revolution).
- the difference angle ⁇ (x) is calculated. This angle corresponds to a pulse number nl (x) - ⁇ (x) * I.
- the control unit of the motor 35 compares the number of pulses that the incremental encoder sends with the number of pulses determined by the computer. When this is reached, the control unit switches off the engine 35.
- the control device receives the instruction analogous to FIG. 7, the angular position ⁇ to change from step to step in each case by a constant difference angle.
- the assigned diameters are entered in the form of a table.
- the motor 35 is directly connected to the shaft of the turntable 10, so that the motor 35 and turntable 10 always change their angular position to the same extent.
- the comparison between the number of pulses determined by the computer and the number of pulses output by the incremental encoder takes place in the computer.
- the motor 35 is equipped with an absolute encoder.
- An absolute value is assigned to each angular position of the motor 35 and the turntable 10 coupled directly to it.
- a full turn is e.g. B. divided into 4,096 absolute values.
- the absolute value is fed to the computer and compared there with the angle ⁇ (x) determined analogously to FIG. 3.
- Figures 11 and 12 relate to a specific example, namely the winding of a bulky
- Carpet fiber with a winding machine essentially according to FIG. 1.
- the process parameters and the dimensions of the winding machine are given in Table 1. They correspond to normal practice.
- the state of the system at a certain instant is characterized by the instantaneous diameter DS of the coil 16 and by the angle ⁇ that the turntable 10 is currently occupying. If this state in FIG. 11 corresponds to a point that lies exactly on the curve, then the contact roller 12 touches the surface of the coil 16 without pressure.
- the actual angle ⁇ is smaller than the function indicates. This means that the contact roller is pressed into the coil.
- the indentation depth depends on the elasticity of the coil 16 with the contact pressure, with the contact roller 12 abuts the coil. A contact pressure is always effective during operation. It is important to keep them under control. This is done by keeping the indentation under control.
- Figure 12 shows a small section of the curve of Figure 11 in a thousand times magnification.
- a zigzag curve can be seen under the curve in FIG. It symbolizes the tracking of the turntable according to the invention.
- the time interval in which the zigzag curve is traversed lies at an arbitrarily selected point in the course of the coil travel.
- the system is in a state which is characterized by the point 0.
- the coil diameter is just over 18 cm, and the turntable is in a position ⁇ O, i.e. a little over 28 °.
- the motor of the turntable is switched off in the O state.
- the diameter of the coil, which is continuously increasing, is monitored.
- Diameter with the stored diameter shows that the coil has reached the stored diameter, the associated angle ⁇ 1 is read from the curve for this purpose or calculated using the formula. This requires a conventional microprocessor control z. B. 0.025 s. In the meantime, the
- Coil reached state Q1 that is, the diameter has grown a little, but the angle is still ⁇ 0.
- the motor 35 of the turntable 10 is turned on, and the Angle is increased to the value ⁇ l.
- the enlargement of the angle ⁇ is approximately 0.01 °.
- a time span of 0.075 s is required for the angle adjustment.
- the state R1 is then reached.
- the path Pl Ql Rl is thus covered in a total of 0.1 s. Since during this period the
- the indentation depth results from the horizontal distance by multiplication by A / 2.
- the indentation depth fluctuates with a small amplitude around an average value and always remains below 0.04 mm in the interval under consideration.
- the corresponding changes in the contact pressure are of no importance in many practical cases. This applies in particular to the carpet fiber that is wound up according to the example considered. Such fibers are very bulky, and the spools wound from the fibers are relatively soft and can be easily pressed in.
- Diameter of the contact roller d 7.2 cm
- Thread speed v 4000 m / min
