Circuit arrangement for controlling and / or regulating the drive of a ring spinning or ring twisting machine

Field of application of the invention

The invention "relates to a circuit arrangement for controlling and / or regulating the Antriebo a ring spinning or ring twisting machine," in which the drive of the ring spinning or ring twisting machine depending on the Kopsaufbau, which requires a steady and iridescent lifting movement of the ring rail is affected the means for generating the steady and iridescent Hubbewsgung the ring rail, means for outputting signals from the steady and iridescent lifting movement of the ring rail and means for processing the output signals are arranged and the means for processing the output signals with the drive of the ring spinning or twisting machine are connected »

Characteristic of the known state of the art

By a publication in the international textile bulletin, branch expenditure spinning, 4th quarter 1982, S, 403 to 414, optimization in the yarn production dvxch speed-controlled ring spinning machine drives, Hans Rudolf Grunder, a circuit arrangement of the kind mentioned is known, in which a magnetic Initiator with the ring rail, which performs a iridescent lifting movement, contactlessly connected. Shortly before reaching the upper reversal point of the ring rail, this initiator emits a digital signal which, after appropriate processing, leads to the feedback of the setpoint value of the drive. Shortly after the upper reversal point, a digital signal is emitted again after processing

leads to an increase in the setpoint of the drive. The disadvantage here is that for processing the output signals high effort is required ₀

Object of the invention

The purpose of the invention is to reduce the effort required to process the emitted signals,

Explanation of the essence of the invention

The object of the invention is to obtain analog signals from the iridescent lifting movement of the ring bank. "

This is achieved according to the invention by using analogous means as a means of dispensing. Signals from the iridescent lifting movement of the ring rail a potentiometer is arranged «In a further embodiment in which, as is apparent from the prospectus ring spinning machine 2113 B of the VEB Spinnereimaschinenba · Karl Marx City, printing number Ag 07 001 83 III 8 9 2182, as a means sum generating the iridescent lifting movement a cam, a Wagenhebe.l and a chain are arranged, the potentiometer is connected to the carriage lever.

embodiments

In the accompanying drawing show

Fig. 1 shows a circuit arrangement in a schematic representation

Figo 2 shows the course of the spindle speed in response to the iridescent lifting movement

Fig. 3 shows a further circuit arrangement in a schematic representation

A ring spinning machine is driven by means of adjustable drive 1, which is designed as a DC motor with a thyristor controller. Hand-operated potentiometers are input setpoint speeds for the winding stages application, piecing / spinning, main spinning and underwinding. Wear on the ring spinning machine ^ ind spindles 2 dio bobbins 3 arranged on a spindle rail 4 ( "Figo I) ₀ A ring rail carrying rings, not shown, the ring rail 5 results in a steady and an iridescent stroke movement that requires the Kopsaufbau. To generate The cop 3 has an approach at the foot of the sleeve on which cone layers are built up, to which the ring rail 5 is gradually guided upward in a continuous stroke movement Lifting movement, the ring rail 5 is slowly raised at each stroke and sets the main windings, then 5 cross windings to avoid the falling of the main windings are placed in the faster lowering of the ring rail.The lifting height h is always the same (Figo 2) "Depending on the position of the ring rail is the diameter of the cop 3 to be wound and thus the Eewicklungsgeschwindigkeit different. In order to technologically optimally operate the ring spinning machine at each position of the ring rail 5, the drive 1 of the ring spinning machine is influenced. On the ring spinning machine, a circuit arrangement for controlling and / or regulating the drive 1 of the ring spinning machine is arranged. In this circuit arrangement are means for outputting signals arranged from the continuous and from do: ¹ iridescent lifting movement, the means for outputting signals from the iridescent stroke movement give analog signals and as a means for delivering ana- ·

Loger signals from the iridescent lifting movement of a potentiometer 6 is arranged. Subsequent to the potentiometer 6 means 7 are for processing the output signals arranged the means 7 for processing the output signals of the ring spinning machine are connected to the drive 1, which also drives the spindles 2 ₀

Me effect is following

Depending on the achieved position of the ring rail 5, which expresses itself in a certain position of the means for generating the iridescent lifting movement, the potentiometer 6 outputs an analog signal by providing a DC voltage This DC voltage is superimposed on the set reference voltage »results from the overlay Also, a speed N ^ of the spindle 2, which corresponds to the respective pitch of the ring rail during iridescent lifting movement (Fig ₀ 2). For the spindle speed, this means that the set setpoint speed η is superimposed on a resulting change in the voltage speed by during the lifting of the ring rail 5 in the time t ^ the spindle speed of n ^ lowered to η and during the lowering of the ring rail fifth in the time to from η to n ^ is increased. This process is repeated for the duration T of each stroke, "The superposition of ice in the Bewick] .un ₆ östufen create, piecing / spin-out, Hauptöpinnen and lower winds possible, it can be carried out on all or only selected Bewicklungsstufen ,,

In a second embodiment, a cam 8, a carriage lever 9 and a chain 10 are arranged as means for generating the iridescent lifting movement (FIG. 3). O The potentiometer 6 is connected to the carriage lever 9. The further construction as well as the mode of action are as already described ",

The spindle speed can be changed linearly ¹ to the lifting movement of the ring rail ·
