Definitions

the invention relates to a positioning drive within a printing press according to the preamble of claim 1.
the remote register adjustment devices, remotely adjustable color metering devices and format-dependent stops or the like are to be mentioned here as examples.
DC motors, synchronous motors or stepper motors are usually used as positioning drives. These motors then usually act on the link to be adjusted via a reduction gear. So that the actual position of the member to be adjusted can be detected, an actual position transmitter, for example a potentiometer, is assigned or arranged to the motors or within the transmission. However, additional actual position transmitters are cost-intensive.
a stepper motor can be equipped without an actual position transmitter, but only in cases in which it is always ensured that the link to be adjusted or the transmission is not blocked or the rotor of the motor does not rotate asynchronously due to another heavy gear.
the use of a stepper motor, possibly also with a proximity sensor to detect the zero position, is therefore only limited to a few applications.
Brushless DC motors are increasingly used in printing machines today. In positioning drives, however, they are used like conventional DC motors, ie in conjunction with an additional actual position transmitter, for example in the form of a potentiometer.
the object of the present invention is therefore to develop a positioning drive according to the preamble of claim 1 in such a way that it is structurally simple and inexpensive.
a brushless DC motor which, in principle, has an integrated device for rotor position detection.
the signals of the rotor position detection of the brushless DC motor are fed to an electrical circuit for position encoder evaluation, which adds them up in the manner of incremental signals or subtracts them from a counter reading in the opposite direction of rotation and calculates the actual position of the positioning drive or the link driven by it.
a brushless DC motor consists of a rotor 1 and, according to its number of poles, a number of turns 2 (here, for example, three windings) in the stator.
the axis of the rotor 1 is connected, in a manner not shown, to a link to be adjusted, for example a register adjustment device, via a largely play-free gear.
a position sensor 3 for example in the form of a disk magnet, is connected in a rotationally fixed manner to the rotor 1. Marks on this Position sensors 3, for example permanent magnets or optically scannable markings, are detected by sensors S1, S2, S3. The fact that three sensors S1 to S3 are provided here according to the number of windings can be seen as an example.
the signals from the sensors S1 to S3 are fed to a commutator control 4, which determines the position of the rotor 1 from these signals in a manner known per se and controls the commutation accordingly, that is to say reverses the polarity of the windings 2 so that the rotor 1 in the intended direction of rotation runs.
the signals from sensors S1 to S3 are additionally fed to a circuit provided according to the invention as position encoder evaluation 5, which is essentially designed as a counter (summer) and thus determines the actual position of the link to be adjusted by rotor 1. According to the required accuracy, it can be provided that the position sensor evaluation 5 evaluates the signal of only one, two or all sensors S1 to S3 in order to obtain the actual position. In the event that the position encoder evaluation 5 only a signal from a sensor e.g. S1 evaluates, the signal of a second sensor is also evaluated to obtain information about the direction of rotation of the rotor 1.
the position sensor evaluation 5 now carries out a summation or, in the opposite direction of rotation, a subtraction of the position pulses supplied by the sensors S1 to S3.
the gearbox connected downstream of the rotor 1 or the member to be adjusted (not shown) has a fixed stop position, in which the rotor 1 blocks, so that the position sensor evaluation 5 then a zero if signals of the sensors S1 to S3 are absent therefrom Position can be derived, for example, in the form of a predetermined counter reading.
an analog or digital signal of the actual position of the rotor 1 or of the adjusting element connected downstream of it is provided.
This analog or Digital signal is fed to a positioning controller 6, which receives an analog or digital signal as the target position at another input.
the positioning control 6 is designed in a manner known per se as a comparator and determines the direction in which the rotor 1 is to be driven by forming the difference between the desired and actual positions. In accordance with this target / actual position comparison, the positioning controller 6 sends a corresponding signal to the commutator controller 4 so that it drives the rotor 1 in the correspondingly required direction or brings it to a standstill.
