- the system is provided with a driven shaft, wherein at least a first and a second gear motor drive the shaft, wherein a torque caused by a tensile force acts on the shaft, wherein the tensile force is generated by a device, wherein the torque generated by the first gear motor counter acting on the torque caused by the tensile force and the torque generated by the second gear motor acts in the direction of the torque caused by the tensile force.
- the advantage here is that a high setting range, so a wider range of adjustable torque, the shaft driving device, ie the two geared motors, can be achieved.
- the shaft driving device ie the two geared motors
- the torque of the first geared motor generated when the current is not energized can also be compensated. In this way, the adjustment range is expandable to almost zero.
- the output shaft of the first and the output shaft of the second gear motor are rotatably connected to the shaft, in particular wherein the two output shafts are each designed as hollow shafts and are respectively mounted on the shaft.
- the two output shafts can be arranged one behind the other, ie in the direction of the shaft axis, on the solid shaft.
- the first and the second geared motor each have a motor-driven or regenerative driven by an electric motor gear, each electric motor is fed in each case by a respective inverter.
- the advantage here is that although the transmission generates a torque caused by bearing losses, Gereteölplantschmaschinee and further friction losses, in particular the teeth, when non-energizing, but that the second gear motor is able to compensate for this torque.
- the second geared motor can compensate for the speed-dependent intrinsic resistance of the first geared motor.
- At least four times or at least ten times greater torque can be generated by means of the first geared motor than by means of the second geared motor and / or substantially the first geared motor defines the upper limit of the position of the
- Geared motors generated can be introduced into the shaft torque.
- the advantage here is that the second gear motor must have only a small size and thus is inexpensive.
- two gear motors are arranged on the shaft, however, only the first is used to generate the actual drive torque.
- the second is only the compensation of the torque losses of the transmission of the first geared motor.
- the torque generated by the second geared motor and guided to the shaft substantially equal to that of the latter
- a sensor for determining the tensile force is arranged in the system, wherein the detected actual value of the tensile force is fed to a controller of the inverter supplying the first geared motor.
- the second geared motor is operated as a relief machine.
- the second geared motor adjusts to a torque value determined according to a characteristic curve M (n), which is assigned to the actual rotational speed.
- the first geared motor is regulated to the nominal tension.
- the controller of the converter supplying the first geared motor is supplied with a setpoint value for the tractive force.
- the advantage here is that on a target value of traction is hinregelbar.
- the controller of the converter supplying the second gear motor is supplied with a speed actual value, from which a torque setpoint to be reached is determined according to a characteristic curve.
- the characteristic describes the speed-dependent inherent inhibition of the first drive or compensates over.
- a radius of a winding roll is determined and a tensile force is determined
- the rotational speed of the winding roll is determined, wherein the deviation of the detected tensile force is determined to a predetermined target value of tensile force and is converted by means of the determined radius in a torque value to which the torque generated by a first gear motor is controlled, the second geared motor torque generated, which is adjusted to a torque setpoint, which is determined as a function of the detected speed of the winding roll and / or the shaft according to a characteristic curve, in particular wherein the characteristic curve
- the first drive is selected to be less powerful than the second drive, a refined and thus improved controllability within the setting range can be achieved as a result of the more refined current resolution of the less powerful drive. However, then the fine adjustment range is determined only by the less powerful drive.
- FIG. 1 shows a schematic view of the system according to the invention.
- FIG. 2 shows a functional diagram of the converters of the drives, that is to say of a first and a second geared motor.
- FIG. 3 shows the enlargement of the torque setting range by adding a second geared motor to the drive arrangement.
- FIG. 4 shows the schematic view of the system according to the invention in an oblique view, wherein the sensor roller for determining the tensile force F is not shown.
- a winding roller 2 is rotatably connected on a shaft 1, on which a winding material, such as paper or fabric, can be wound.
- the winding material is unwound with a force F, ie an actual value of force, wherein a device not shown causes this tensile force F.
- a sensor S is foreseen, which detects the actual value Fjst the tensile force F.
- the shaft 1 is connected to a first geared motor, wherein the geared motor counteracts the tensile force F.
- the geared motor generates a torque M which is between a maximum value and a minimum value.
- the maximum value M_max of the torque M is determined by the size and construction of the geared motor.
- the minimum value M_min of the torque M is the value that occurs when the motor is not energized.
- the transmission is driven by the winding roller 2 and the engine acts only by means of his
- the acting on the winding roll torque M is of radius, ie half
- the shaft 1 of the winding roller 2 is connected not only to the output shaft of the first geared motor 41 but also to the output shaft of a second geared motor 42.
- both torques generated by the geared motors (41, 42) act on the shaft 1 of the winding roller 2.
- the second geared motor 42 counteracts the torque _min generated by its gearbox when the first geared motor 41 is de-energized, ie the self-locking of the first geared motor 41.
- the second acts
- Gear motor 42 with its torque generated by it on the tensile force increasing.
- the torque generated by the first gear motor 41 has a degrading effect on the tensile force F, since it counteracts it.
- the torque generated by the second gear motor 42 has an increasing effect on the shaft, in particular tensile force F, since it acts in the direction of the force generated by the device, not shown, the force generated by the two geared motors (41, 42) and the forces of the not shown device is zero in steady state operation.
- the size of the second geared motor 42 is smaller executable than the size of the first geared motor, since the second geared motor must apply only the amount _min of the first geared motor.
- the adjustment range of the entire drive is thus traversed by the converter of the first geared motor 41.
- the second geared motor 42 compensates only the self-locking.
- the adjustment range of the first geared motor 41 which would only be present between _min and M_max, can be expanded by means of the second geared motor. In this case, as a lower limit even almost a vanishing torque allows.
- a motor preferably a synchronous motor or an asynchronous motor is used and as a gear transmission with a spur gear, with a planetary gear or with a non-self-locking angle gear.
- Inverter 21 of the first geared motor 41 is supplied, which has a controller to which this actual value F_ist is supplied.
- the controller is also a setpoint F_Soll fed, which corresponds to the desired draft amount.
- the control deviation is fed to a linear regulator and multiplied by that of a sensor detected or determined by another method radius of the winding roll 2 in a torque value M1_soll, to which the first inverter 21 hinregelt.
- the inverter 22 which feeds the second geared motor 42, receives the actual value njst of the rotational speed of the shaft and determines according to a characteristic M (n) a torque setpoint M2_Soll, which is thus a function of the rotational speed n.
- the characteristic M (n) describes the speed-dependent self-locking of the transmission of the first geared motor.
- the intrinsic resistance caused by the ⁇ lplantschpolee rolling friction of the rolling elements of the bearing and the friction losses, in particular the meshing teeth.
- the first inverter 21 feeds the electric motor of the first geared motor 41
- the second inverter 22 feeds the electric motor of the second geared motor 42.
- the controller of the first inverter 21 receives as a setpoint the setpoint F_Soll the tensile force, which is to prevail on the winding roll 2. From the control deviation, ie deviation of the actual value F_act from the setpoint F_setpoint, a manipulated variable is determined, the controller in the simplest case being a linear controller, such as a PID controller. Alternatively, however, a simple proportional controller or a PI controller can be used. As shown in Figure 2, the control value is a torque value which is generated by means of said multiplication with the radius of the winding roll 2 by the first inverter 21 fed electric motor with gear. The setting range is between M_min and M_max.
- the controller of the second inverter 22 receives as the actual value of the detected at the shaft speed, from which by means of the speed-dependent self-inhibition characteristic M (n) of the
- Torque setpoint M2_Soll is formed on the torque of the second
- Geared motor is adjusted.
- the second geared motor 42 thus compensates the inherent inhibition of the first geared motor 41.
- the target value F_Soll is reached in tensile force, which is to prevail on the winding roll 2.
- the maximum torque that can be generated by the drives is M_max and the minimum torque that can be generated by the drives is M_min.
- Torque M (n) which occurs at Fishbestromen the first geared motor and as a characteristic M (n) the second gear motor for compensation at least predetermined.
- overcompensation is also possible. It is advantageous in the
- the range 52 alone is effective as the setting range of the entire drive, which comprises the first and the second gear motor;
- the area 53 is ineffective as a parking area, since it is compensated
- the system is an unwinder or rewinder.
- the setting range of the two gear motors that is (R_max x F_max) / (R_min x F_min), is greater than 30 by means of the invention, where R_max is the maximum radius of the winding roll, where R_min is the minimum radius of the winding roll, where F_max is the maximum tensile force that occurs and F_min is the minimum tensile force occurring.
- the controller of the two inverters are reversed, whereby the inverter of the more powerful first gear motor gets the actual speed n_ist supplied and according to a characteristic M (n) the
- Torque setpoint M_Soll determined and routed to the shaft by means of the geared motor.
- the controller of the converter of the second geared motor gets the actual force F_act and the determined or detected radius of the winding roller 2, so that it determines a control value from the comparison with the desired force F target and thus operates the second controller such that the actual force is controlled to the desired force.
- the radius of the winding roll is not detected directly by a sensor but by means of the detected unwinding or
- Winding speed of the winding material and the detected rotational speed of the shaft determined by the quotient of the speeds is formed.
- a transmission is arranged between the shaft and the winding roller, so that the rotational speeds differ by a factor.
