Description

splicing machine and simplifying the circuit design of the device. The proposed wiring diagram of a four-wire counter using a number of elements (voltage regulator, current regulator transformer 1 - 2-TTU resistor and others), which together provide the developed device with specified functional properties, minimizes the effect of changes in the supply voltage on the measurement accuracy. At the same time, the circuit realization of the device is simplified, since in order to obtain information on the amount of produced products

the machine does not require the bleeding of a special network and the installation of control elements and resistors for each workplace. This increases the reliability of the measurements and facilitates the operating conditions of the device. For the task set, the choice of the circuit controller of the current regulator transformer 1 is the 2-TTU resistor and the parameters of its elements, allowing the current to be adjusted to compensate for the constant component of the current control system of the spinning chambers corresponding to the idle mode of the spinning machine. 1 ID

The invention relates to the control of spinning machines and can be used in the textile industry.

The aim of the invention is to improve the accuracy of the control.

The drawing shows a functional diagram of the device.

The device contains a step-down single-phase transformer 1, a variable resistor 2, transformers 3 and 4, a three-phase step-down transformer 5, a spindle camera control unit 6 (not shown), an electric force counter 7 and a voltage regulator 8.

The primary windings of transformers 1 and 5 are connected to the corresponding terminals of the three-phase supply network. So the secondary winding of the transformer 1 is connected in series with the adjusting resistor 2 and the primary winding of the transformer 3, and the secondary winding of the transformer 5 is connected to the control unit 6, in one of the phases of which the primary winding of the current transformer 4 is connected. The secondary windings of the current transformers 3 and 4 are interconnected via terminals 1 and 2 in opposite directions. Between the terminals 2 of transformers 3 and 4 of the current, the current windings of the electric power meter 7 are switched on, and the terminal 2 of the transformer

4 current is connected via terminal 1 of the meter 7 to the first and second current windings connected in series through terminals 3 and 4, the third current winding of meter 7 is connected to the latter through terminals 6 and 9, which is connected to the second terminal of the current transformer 3 via terminal 7 . The input of the voltage regulator 8 is connected to two terminals of the three-phase power supply network, and one of its inputs is connected via terminal 2 to the first input of the first winding of the electricity meter 7. The first output of the stabilizer 8 voltage is connected via terminals 5 and 8 to the first inputs of the second and third windings of the electricity meter 7, and its second output through terminal 10 to the second inputs of the first, second and third windings of the voltage meter 7.

The control unit 6 contains electromagnetic clutches that are turned on and off by yarn break sensors (not shown), the number of which corresponds to the number of spinning chambers.

The device works as follows.

The spinning machine is turned on in idle mode, at which the electromagnetic clutches of the control unit 6 are disconnected (this stops the supply of the tape to 11pl, 1yr 1e of the chamber). On the second coil of the ri.ianc-format A, a current arises, the magnitude of which is due to the power consumption of the spinning machine used by the electric energy management unit 6. Using an adjustment resistor 2, the current in the secondary winding of transformer 1 is changed so that the voltage difference between terminals 1 and 2 of transformers 3 and 4 of the current is zero (counter 7 does not record power consumption).

During operation of the pronger machine in the operating mode, the electric power consumption by the control unit 6 varies in proportion to the number of working spinning chambers (into which the feeding tape is fed). In this case, the first, second and third current windings of the meter 7 consume a current whose magnitude is proportional to the current passing through the primary winding of the current transformer 4. The stabilizer 8 provides the stabilized supply voltage of the first, second and third windings of the electricity meter 7.

The productivity of the spinning machine is monitored by the amount of electricity consumed, counted by meter 7, for a certain period of time.

The transition from the number of consumed e-. my electricity to the amount of yarn produced is carried out by the ratio
