Definitions
- the invention relates to a drive device for the multiplicity of spindles of a ring spinning machine, with respective tangential belts driving sections of spindles in each case, which can be driven by one electric motor each.
- PRIOR ART DD 287 961 A5 and DD 287 962 A5 disclose drive devices for the working units of a spinning or twisting machine, which are driven in sections by a plurality of tangential belts. No statement is made about the type of drive motors. The problem of synchronous running of the tangential belts is not addressed.
- DE 34 41 230 discloses such a drive in which the sectional tangential belts are driven by induction motors.
- Asynchronous motors run in particular when they are not equally loaded, not synchronous.
- synchronous running of the tangential belts must therefore be ensured in all sections. This is achieved by the fact that the tangential belts of adjacent sections wrap around common deflection rollers which ensure this synchronous operation.
- the object of the invention was therefore to achieve synchronous operation of the sectional tangential belts on a drive device of the type mentioned initially without these being guided via common deflection rollers and thus having to run at different heights. It solves this problem with the features mentioned in the main claim.
- By feeding the synchronous motors with matching frequency synchronous operation of all sectional tangential belts is achieved without them having to be mechanically coupled with each other.
- the matching frequency can be generated by providing a frequency converter common to all synchronous motors, which feeds all the synchronous motors.
- each of the synchronous motors can be equipped with an individual frequency converter. This has the advantage that it is not necessary to provide frequency inverters of different power levels, depending on the number of synchronous motors to be fed. All synchronous motors are associated with them in terms of performance and otherwise adapted frequency converter.
- one of the frequency converters controls the frequency of the other in a master / slave ratio.
- a resolver can be provided which detects the angular position of the synchronous motors and forwards them to the frequency generator. So this can act on the synchronous motors during startup with phase-correct supply frequency or regulate at speed deviations to the desired speed.
- Figure 1 is a plan view of the spindle drive device of a ring spinning machine.
- Fig. 2 is a plan view of a differently designed spindle drive device;
- Fig. 4 is a plan view of a deflection point of two sectional tangential to a drive pulley or spindle row on the other side of the ring spinning machine.
- Figure 1 shows the floor plan of a ring spinning machine 1, which has a plurality not shown spindles on both sides, which are driven in sections by means of tangential 2. Each tangential belt drives a number of spindles on both sides of the machine and in turn is driven by an electric motor 3. These electric motors are designed as synchronous motors. Dir supply current is generated by a frequency converter 4, which generates from the frequency of the network 5 via a DC intermediate circuit alternating (rotating) current certain, preferably variable frequency. The control of this feed frequency takes place in the form of the spindle speed by the machine control 6 the frequency converter 4 via a Interface is specified. In particular, the run-up of the spindles during start-up and their speed reduction at the outlet is controlled by the machine control.
- the supply frequency is passed through a feed line 7 to all motors 3. Due to the synchronous running of all electric motors 3, the tangential belts 2 and the spindles also run synchronously.
- a resolver 9 may be arranged, which decreases the rotational position of this motor and reports back to the frequency converter 4 via a signal line 10. This regulates the supply frequency in the event of a deviation from the setpoint speed in the sense of a reduction in the deviation.
- each of the electric motors with its own frequency converter 4 l5 A 2 , 4 3 , 4 X always the same power level equipped.
- Each of these frequency converter is fed from the network 5 and receives the set speed from the machine controller 6 via a signal line 8 and generates the corresponding supply frequency.
- the machine control 6 also controls only one frequency converter 4i, which is closest to the final frame of the ring spinning machine. This then performs as a master on the control line 8, the frequency converter 4 2 , 4 3 , 4 X of the other sections as slaves.
- the pulleys of the roller pair 13 are perpendicular to the plane of the spindles adjustable to adjust the contact pressure of the tangential 2 to the spindles can.
