Definitions
- the invention relates to a positioning drive within a Printing machine according to the preamble of claim 1.
- positioning drives Today's printing machines, especially sheetfed offset printing machines have a variety of positioning drives.
- remote register adjustment devices Today's printing machines, especially sheetfed offset printing machines have a variety of positioning drives.
- remote register adjustment devices Today's printing machines, especially sheetfed offset printing machines have a variety of positioning drives.
- remote register adjustment devices Today's printing machines, especially sheetfed offset printing machines have a variety of positioning drives.
- remote register adjustment devices Today's printing machines, especially sheetfed offset printing machines have a variety of positioning drives.
- DC motors synchronous motors or stepper motors used. These motors then usually work via a reduction gear on the link to be adjusted. So that the actual position of the link to be adjusted is the Motors or within the gearbox, for example as a potentiometer trained actual position transmitter assigned or arranged.
- additional actual position transmitters are cost-intensive.
- a stepper motor can be equipped without an actual position transmitter are, but only in cases where always guaranteed is that the link to be adjusted or the gearbox is not blocked or by another heavy gear the rotor of the Motors does not run asynchronously.
- the use of a stepper motor, possibly also with a proximity sensor Detection of the zero position is therefore only in a few use cases limited.
- Brushless DC motors are used in printing machines nowadays increasingly used. In positioning drives, however, they become like conventional DC motors used, i.e. combined with an additional actual position transmitter, for example in the form of a Potentiometers.
- a positioning drive within a printing press is known from US Pat. No. 4,398,137. in which the motor drives a link to be adjusted via a gear. That too adjusting member has an opto-electronically scanned disc as an actual position transmitter on, the signals of this actual position transmitter for determining an actual position of the limb are processed. These signals are connected upstream of the engine Positioning control supplied.
- DE-A 3 820 903 discloses a position encoder for a brushless DC motor, where the sensors of the commutator control are arranged outside the motor are. Optically scannable signal tracks of the rotor are via light-guiding Means directed to the sensors. In electronics downstream of the sensors the stator winding is poled according to the rotor position.
- the object of the present invention is therefore a positioning drive to further develop in accordance with the preamble of claim 1, so that it is structurally simple and inexpensive designed.
- a brushless DC motor to use, the principle of a device for rotor position detection has integrated.
- the signals of the rotor position detection of the brushless DC motor become an electrical one Circuit for position encoder evaluation, which this summed up in the manner of incremental signals or in the reverse Direction of rotation subtracted from a counter reading and the Actual position of the positioning drive or that driven by it Limb calculated.
- FIG. 1 basically shows the Basic components of the electrical control of the invention Positioning drive.
- a brushless DC motor consists of a rotor 1 and according to its number of poles from a number of turns 2 (here for example three windings) in the stator.
- the axis of the rotor 1 is in a manner not shown about a largely free of play Gearbox with a link to be adjusted, for example one Register adjustment device connected.
- a position encoder 3 for example in FIG Shape of a disc magnet, connected. Marks on this Position sensor 3, for example permanent magnets or optically scannable Markings are detected by sensors S1, S2, S3. That here three sensors S1 to S3 depending on the number of windings are intended to be regarded as exemplary.
- the signals from sensors S1 to S3 are a commutator control 4 fed from these signals in a manner known per se determines the position of the rotor 1 and accordingly the commutation controls, that is, the windings 2 with respect to the current supply reversed polarity, so that the rotor 1 runs in the intended direction of rotation.
- the signals from sensors S1 to S3 are additionally one according to the invention provided circuit provided as position encoder evaluation 5, which is essentially designed as a counter (totalizer) is and thus the actual position of the to be adjusted by the rotor 1 Limb determined. According to the required accuracy can be provided that the position sensor evaluation 5 only the signal one, two or all sensors S1 to S3 for obtaining the Evaluates the actual position. In the event that the position encoder evaluation 5 only one signal from a sensor e.g. Evaluates S1, it will also Signal from a second sensor to obtain information about evaluated the direction of rotation of the rotor 1.
- the position encoder evaluation 5 now carries out a summation or in reverse Direction of rotation a subtraction of the sensors S1 to S3 delivered position impulses.
- the gear connected downstream of the rotor 1 or the one to be adjusted Link (not shown) has a fixed stop position at which blocks the rotor 1, so that the position encoder evaluation 5 then in the absence of signals from sensors S1 to S3 therefrom a zero position, for example in the form of a predetermined one Derive meter reading.
- This analog or Digital signal is fed to a positioning controller 6 which at another input an analog or digital signal as the target position receives.
- the positioning controller 6 is known per se Formed as a comparator and provides by difference of target and actual position, in which direction the rotor 1 is to be driven. According to this target / actual position comparison the positioning controller 6 gives a corresponding one Signal to the commutator control 4 so that the rotor 1 drives in the required direction or at a standstill transferred.
