DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire drawing data recording device for continuously recording wire drawing tension applied to a cable being drawn.

[0002]

2. Description of the Related Art The extension tension is continuously recorded as a cable is extended, and is used as extension history data for the extension section. The recording of the extension wire for this purpose is conventionally performed by recording means such as a pen recorder, and the data is obtained as a result of correlating the extension wire tension with the elapsed time. That is, the tension data is recorded while a recording sheet having a horizontal axis indicating time and a vertical axis indicating tension value is flowed at a constant speed.

Therefore, even if the wire drawing operation is temporarily interrupted, useless recording is performed on the continuously flowing recording paper. If the interruption time is long, the recording paper runs out and recording of tension data is stopped. Was temporarily dropped out, or in some cases, no further recording was made. In addition, the tension data correlated with the time has a disadvantage in that it is difficult to grasp the correspondence between the fluctuation state of the wire drawing tension and the actual wire drawing situation due to the interruption time.

[0004]

SUMMARY OF THE INVENTION Therefore, according to the present invention, it is possible to always record the wire drawing tension in correspondence with the actual wire drawing situation, and to uselessly record even during interruptions during the wire drawing work. It is an object of the present invention to provide a wire drawing data recording device without any.

[0005]

A wire drawing data recording apparatus according to the present invention comprises a data creation unit and a processing unit, and creates wire drawing data in which the wire drawing tension is correlated with the wire drawing length in the data creation unit. However, the extension data can be recorded on a recording medium by the processing unit.
The data creation unit consists of a length measuring means for measuring the length by counting the length pulses generated along with the extension of the cable, and recorded length data for each fixed length from the data provided by the length measuring means. Length data capturing means, a timing setting means for providing a timing of recording length data based on a signal provided from the length measuring means, and a record corresponding to the recorded length data captured by the length data capturing means. Tension data capturing means for converting tension data into digital data from tension data supplied as analog data, and recording tension data while controlling the length data capturing means and the tension data capturing means based on a signal from the timing setting means; And control means for creating extended line data in which the recorded line length data is correlated.

This wire drawing data recording device is designed to record tension data in correlation with the wire length, which is the length of a cable that has been wire drawn. As a result, the wire drawing operation is interrupted. In the meantime, the recording of the tension data is interrupted by itself during that period, so that there is no needless recording. In addition, the fluctuation state of the wire tension corresponds to the actual wire length of the cable, so that it is possible to create recording data that allows the user to see at a glance the correspondence between the tension fluctuation and the wire drawing state. .

In such an extension data recording apparatus, if a timing setting means is provided with a selection means so that different timings can be selectively set by the selection means, an extension wire suitable for various different extension conditions is provided. Can be recorded with data.

[0008] Further, such a wire drawing data recording apparatus includes:
It is further preferable that a speed data capturing means is added so that the extension speed data can be recorded in addition to the tension data.
It is preferable that the extension speed data can be recorded in correlation with the strip length data.

[0009]

An embodiment of the present invention will be described below. As shown in FIG. 1, the extension data recording device 1 includes a data creation unit 2 and a processing unit 3, and each of an extension vehicle placed on a drum site or an overhead line vehicle placed on an engine site. Alternatively, a strip length pulse signal and a tension data signal supplied via an operation panel T for operating both of them collectively are taken into the data creating unit 2 and the extension wire tension and the extension wire length are correlated therefrom. For example, extended line data as shown in FIG. 5 is created, and the extended line data can be recorded or displayed by the processing unit 3.

The data creating unit 2 creates wire drawing data in which the wire drawing tension and the wire drawing length are correlated as described above. As shown in FIG. The apparatus includes a length data capturing means 6, a timing setting means 7, a tension data capturing means 8, and a control means 9.

The length measuring means 5 is for measuring the extension wire length based on the count of the length pulses (φa, φb) outputted from the operation panel T. The preliminary counting means 10 and the BCD up / down The length data forming means 11 uses a counter. More specifically, the preliminary counting means 10 counts the length pulses output from the operation panel T in units of, for example, one pulse of 0.24 millimeters, and generates one pulse per one meter of the length, for example. Outputs a secondary length pulse. Then, the output pulse of the preliminary counting means 10 is applied to the length data forming means 11.
The length data in the format of "xxx" meters is formed by counting.

Here, a correction coefficient input means 12 is connected to the preliminary counting means 10, and by inputting a correction coefficient which is predetermined by the correction coefficient input means 12, the characteristics of the extension line and the cable are obtained. The correction can be performed according to. This is based on the relationship that the length pulse output from the operation panel T is given by an encoder that detects the rotation of the drum of the wire drawing vehicle or the overhead line vehicle, and the number of rotations of the drum is regarded as the cable length of the cable. It is processing that is. That is, the strip length per rotation differs depending on the diameter of the drum depending on each of the pulleys or the overhead pulleys, and the strip length per rotation also depends on the type of shoe groove of the drum and the diameter of the cable to be drawn. Since the lengths are different, correction according to these characteristics is performed.

It is to be noted that connected to the preliminary counting means 10 is a strip display 13 so that the count result of the preliminary counting means 10 can be displayed there.

The length data fetching means 6 is for fetching recording length data for each fixed length based on the timing given by the timing setting means 7 as described later, and is formed by a latch circuit. Control means 9
Under the control described below, the recording length data to be taken in from the output data of the length measuring means 5 is temporarily held, and then output to the control means 9.

The timing setting means 7 is for setting the timing of taking in the recording length data by the length data taking means 6, and is formed by a divider 14 and a flip-flop 15. The divider 14 is a selecting means for selecting a timing in different length units, and a signal outputted from the length measuring means 5 (this signal is obtained by directly changing the secondary length pulse from the preliminary counting means 10). If it is to be output, one output will be output for every meter in length).
1 / of the coefficients given as 2, 1/5, 1/10
The signal is flip-flop 15 every 2 counts when 2 is selected, that is, every 2 meters, or every 5 count when 1/5 is selected, that is, every 5 meters. And a timing signal is output from the flip-flop 15 to the control means 9 at the same time.

The tension data capturing means 8 is for capturing the recorded tension data as digital data from the tension data Dt supplied as analog data via the operation panel T, and is an A / D combined with a sample and hold circuit. A converter is used, and under the control described below by the control means 9, the recording tension data can be captured in synchronization with the recording strip length data capturing timing.

The control means 9 is based on the timing signal from the flip-flop 15 and controls the length data fetch means 6
Also, while controlling the tension data taking-in means 8, it has a role of creating extended line data in which the recording tension data and the recording strip length data are correlated.

That is, when a timing signal is received from the flip-flop 15, a latch signal is output to instruct the length data capturing means 6 to temporarily hold the recording length data to be captured, and at the same time, to the tension data capturing means 8. Also output a capture signal. In the tension data capturing means 8 receiving the capture signal, the tension data at that time is held by the sample and hold circuit, and the held tension data is converted into digital data by the A / D converter. Output. As a result, the correspondence between the recording tension data and the recording line length data is given, and the extension line data in which the recording tension data and the recording line length data are correlated is output from the control means 9 to the processing unit 3.

The control means 9 which has completed the output of the extension data outputs a reset signal to the flip-flop 15, whereby the flip-flop 15 enters a standby state for the next timing.

A portable personal computer is used for the processing unit 3, and the extension data supplied from the control means 9 is recorded on a recording medium such as a flexible disk F for later use, or a printer is used. The data is output via the P and used as reference data on site, and can be displayed on the display 3d in parallel with these records.

The wire drawing work is performed over several days.
In the meantime, nighttime work interruption may be interposed, in which case the record of the next day will be resumed from the section chief taken in at the end of the work on that day. Therefore, it is necessary to hold the length data at the end of the work. The length data may be stored in the length data capturing means 6 using a backup power source, or may be stored from the flexible disk F. You may make it read.

FIG. 3 shows a data creation unit 20 according to another example. The difference between the data creation unit 20 and the data creation unit 2 is that a timing setting means using a sequencer commercially available as a standard product is used. The other structure is the same as that of the data creation unit 2 in that the 21 is formed.

FIG. 4 shows a data creation unit 30 according to yet another example.
Thus, in addition to the tension data, the extension speed data can be recorded. That is, the speed data capturing means 31 having the same structure as the tension data capturing means 8 is provided in parallel with the tension data capturing means 8, and the tension data Ds supplied as analog data via the operation panel T is provided.
Thus, the recording speed data correlated with the strip length data can be created by the control means 9 in the same manner as the recording tension data.

The wire drawing speed data recorded in this way is used together with the tension data for later evaluation of wire drawing quality. That is, the wire drawing speed is a burden factor for the cable together with the wire drawing tension, and is used for evaluating whether or not this load has exceeded a prescribed value.
