本発明は金属線被覆設備の調整方法を実施する
ための装置に係る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for carrying out a method for adjusting metal wire coating equipment.

ラムに巻取られる。 Coated equipment is particularly used for insulated conductors used in telephone equipment or general electrical equipment. The demand for the above-mentioned conductors is steadily increasing year by year, and the need for high-output, high-production equipment is therefore increasing. The equipment consists of an extruder with a head designed to continuously press a layer of molten plastic material onto the metal wire through which it passes. The thus coated wire then passes through a movable trough where it is sprayed with one or more water jets. Once cooled, the wire enters a winding machine and is wound onto a drum.
この種の設備の生産容量を増大するためには、

数、次いでその温度により決定される。 In order to increase the production capacity of this type of equipment,
It is desired to increase the speed of the metal wire passing through the extrusion head, and conductors with diameters a few tenths of a millimeter have now been realized at speeds of over 2000 m/min. However, insulated telephone wire production must meet strict specifications regarding coating properties, expressed in terms of wire capacitance per meter of travel, which must be within very narrow limits. If the insulation coating consists of an expanded polymer,
The capacitance of a conductor is determined by the coefficient of expansion of the material and then by its temperature.

利用される。 Regulating devices are known which sense this temperature and operate at a switch which controls a heating element housed in the extruder cylinder in order to keep it constant. Although various attempts have been made to improve upon these known devices, their main drawback is their inertia, which measures the capacity of the wire after jacket cooling rather than by measuring the temperature within the extrusion head. It was hot. Capacitance measuring devices are known which operate continuously and compare measured values with predetermined gauge values. These devices provide an error signal giving the measured value deviation from the gauge value in amplitude and sign. This signal is used to control the heating of the cylinder or, in some cases, the running speed of the line.

The object of the present invention is to provide a method and a device that allow high-speed production of coated wires that meet the requirements imposed on the capacitance per meter of travel.

このように所定速度の間、上記構造は押出ヘツド
からの出口と可動桶への入口間の被覆が行き渡る
通路に従うものである。 The present invention allows the capacitance of the coated wire to be affected not only by the temperature of the insulation in the extrusion head, but also by the manner in which the insulating plastic material is cooled and expanded. Between the extrusion head and the movable vat, the coating spans a certain path while in the temperature range where chemical changes occur and, in particular, gas evolution occurs. The final structure of the coating follows these changes.
Thus, during a given speed, the structure follows a path of coverage between the outlet from the extrusion head and the inlet to the movable tub.

実際瞬間に為される。即ちキヤパシタンスが基準
値に達するや否や、可動桶9は停止する。 In the capacitance measuring device 15, the measurement is amplified and compared with a signal corresponding to the desired capacitance value. The output signal of the measuring device 15 is therefore an error signal corresponding to the amplitude and sign of the deviation of the measured capacitance from the reference value. The signal is passed through 16 filters and then sent to the controller 17. And power amplifier 1
8 starts and stops the electric motor 14 or changes its direction of rotation, all so that the electric motor 14 moves the movable tub 9 as soon as the capacitance deviation is measured. If the measuring capacitance is too low,
The expansion time of the plastic material is increased and therefore the movable trough 9 must be close to the extruder head 5. If the measurement results indicate an error of the opposite sign, the movable pail 9 must be moved away from the extrusion head 5. Because the capacitance measuring device 15 continuously measures the high speed of the metal wire 7, the correction is made practically instantaneously. That is, as soon as the capacitance reaches the reference value, the movable tub 9 stops.
可動桶9の位置は適当な検出装置で測定され

に補正されなければならない。 The position of the movable tub 9 is measured with a suitable detection device. The detection device is built into the electric motor 14, for example, and consists of a tachometer of the pinion 18. The displacement of the movable tub 9 in fact ensures rapid adjustment and ensures that the capacitance of the coated wire 7 remains at a constant value.
However, from a long-term point of view, it is important to maintain the movable tub 9 in a substantially relatively stable operating position. Therefore, if the movable tub 9 moves away from the extrusion head 5 as a result of a change in the temperature range of the extruder, then the temperature range
Corrections must be made so that the movable tub 9 can return to its original position after a certain period of time.

温度調節器24により定温に調節される。 The signal sent from the control device 17 to the cylinder temperature control device 19 is also filtered and formed via a conductor 21 to a temperature regulator 24 which controls either the heating element 2 or the cooling system. Controls the transmission of signals to the distributor 20. Usually heating element 2
The temperature is adjusted to a constant temperature by a temperature regulator 24 connected to the cylinder 1 through a thermocouple 23.

ものである。 The temperature regulator maintains the cylinder area in which the thermocouple 23 is set at essentially the same temperature. In order to apply the command signal coming from the control device 19, a resistor is connected in series with the thermocouple 23 and a device is provided for transmitting a signal from the distributor 20 to each terminal of the resistor. The aspect of the signal is equivalent to a modification of the measured value.

知である。 The distributor 20 is equipped with an adjustment member that can freely adjust the operation of each signal in the corresponding thermocouple 23. It is known that in practice it is sufficient for the regulating element to act on the last heating element of the cylinder element in order to obtain the desired change in the temperature of the plastic material leaving the extrusion head 5.

産できることが解つた。 The signal resulting from the capacitance measurement is used to activate the electric motor 14 which displaces the movable tub 9, thus varying the length of the path through which the coating is made between the point where cooling begins and the extrusion head 5, with respect to the capacitance value of the wire. It was discovered that it was possible to produce coated wires that met the strict specifications imposed.

有する電話線を生産することができるのである。 The reaction speed of the control circuit passing through the electric motor 14 and the movable tub 9 is relatively fast, the actuating circuit from the movable tub 9 or the device 17 on the heating system is relatively slow;
Repetitive back and forth movements of the movable tub 9 are eliminated and the control function is therefore stabilized with simultaneous heating of the cylinder adjusted by the position of the movable tub 9 and capacitance measurements. The heating intensity is thus continuously monitored and contributes to maintaining the capacitance of the wire per meter of travel at a value as close as possible to the reference value. The equipment detailed in this manner is capable of producing telephone lines having a capacitance per meter meeting the exacting specifications required.
