Description

[Detailed description of the invention] The present invention relates to a wire drawing device, and particularly to a control device thereof.

Conventionally, as shown in Fig. 1, a plurality of pulling machines 1 are arranged along the extension track (2), and a stop circuit, an alarm lamp circuit, a separate power supply control circuit, a telephone line, and a radio stop circuit are installed along the extension track. A control cable containing a seed control circuit is provided, and each collecting machine (2) is controlled using a control connector box 2, a control panel 3, and a handy wireless stop unit 4. Rather than carry out a line extension and extend the line (2).

As mentioned above (Second, the control cable has many controllers)
Since the connector includes an o-ring, the number of core wires is large, and the temporary installation and removal of the control cable is likely to cause a breakage accident at the soldered part of the connector, which often hinders construction work. The present invention has been made based on the above-mentioned circumstances, and an object of the present invention is to obtain a control device for a wire extending device that can minimize wire breakage accidents.

In the present invention, a two-core cable such as a coaxial cable is used as the control cable, and radio waves of different frequencies are frequency-modulated by various control signals and are transmitted through the control cable to achieve the above object. There is.

The present invention will be described in detail below with reference to the drawings. In Figure 2, in the control panel lo there is a relay By8 connected to the coaxial cable 12 connecting the control box All and the control panel through a filter f with a frequency F, and a relay Ry that turns off the geo 72. A stop circuit 13 consisting of a contact C3, a separate power supply control circuit 14 including a frequency generation circuit of frequency F and connected to the coaxial cable 12, and a separate power supply control circuit 14 including a frequency generation circuit of frequency F3 and connected to the coaxial cable 12 (two connected oil control circuits) 15, DCC connected to coaxial cable 12
Telephones 16 are each provided which are connected to the coaxial cable 12 via the power source 0 layer f4.

On the other hand, in the control box ll, there is an F1 frequency modulation circuit 17 with a frequency F1 whose output terminal is connected to the coaxial cable 12 via a switch PB, and a relay whose output terminal is connected to the coaxial cable 12 via a filter f2 with a frequency F. R
y2, stop circuit 18 including contact C1 opened and closed by this relay, oil control circuit 19 with similar configuration, frequency F4
A telephone set 20 is provided which is connected to the coaxial cable 12 via a filter fz.

In the apparatus of the present invention having the above configuration, the control of the take-up machine, etc. is performed as follows. For example, when the switch PB is closed on the control box side, a frequency-modulated signal with a frequency F1 enters the stop circuit 13 of the control panel 10 via the coaxial cable 12, actuating relay "Yr" and contact C.
, and stop the collection machine. In addition, if the separate power supply control circuit 14 and oil control circuit are operated on the control panel side, the control signal of frequency F21F will energize the relays RYx+RYs of the control box via the coaxial cable 12, stopping the collecting machine and other operations. Take control.

As described above, according to the present invention, various control signals are carried as frequency-modulated signals by a two-core control cable such as a coaxial cable, so disconnection accidents are much less likely to occur than with conventional multi-core control cables. Few. Further, even if a disconnection accident occurs, since there are two cores, the location where the accident occurred can be easily discovered and repaired easily. Furthermore, when the number of control signals increases, there is no need to change the control cable, just by increasing the frequency used. Furthermore, since the control cable has two cores and can be made thinner than conventional cables, it can be easily arranged along the extension line.
