Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a running filament, particularly a steel-core aluminum stranded wire, which is suitable for attaching visible marks at regular intervals to obtain electric wires for pre-pull overhead lines. This relates to a marking device.

Generally, when measuring a linear object such as a steel-core aluminum stranded wire, two fixed points are set apart by the measuring length, and the linear object is moved along a straight track from one fixed point to the other fixed point. A marking device that attaches a mark is installed at a fixed point on the population side, a mark detection device is installed at a fixed point on the exit side, and the detection output of this mark detection device is fed back to the marking device. A measuring method is used to energize.

According to this measuring method, marks are placed on the moving linear object at intervals of the measuring length, and measuring can be carried out continuously. Methods for making the above marking include a method of operating a magic pen 1 as shown in FIG. 1, and a method of spraying as shown in FIG. 2.

The way to operate the magic pen is to use solenoid coil 3.
When a mark signal is received, the magic pen 1 moves in the direction of the arrow, thereby bringing the tip 5 of the magic pen into contact with the traveling striated body 4. In this case, the tip of the pen rubs the outer surface of the running filament 4 to make a visible mark, so the pen gets caught on the strands of the filament and the width of the visible mark changes. However, accurate marking is difficult.

In the spray method, when a mark signal enters the solenoid coil 6, a lever 7 operates in the direction of the arrow, thereby pushing the upper end 8 of the spray 2, thereby spraying the outer surface of the traveling filament 9. However, since this method uses atomized ink, when the mark width is narrowed, the amount of atomized ink that is emitted is constant, so the color becomes thinner, and the color of the spray becomes thinner. Color unevenness occurs between the beginning and end, making stable marking difficult.

For this reason, marking devices using quick jets have recently been proposed.

This type of marking device drives a dinit nozzle in a direction across the linear object in response to a marking command within a plane perpendicular to the running direction of the linear object. Ink is constantly ejected from the nozzle, and the shutter, which normally blocks the inkjet and prevents it from flying onto the linear object, is opened to drive the nozzle. When doing this, it is necessary to perform a two-stage operation in which the shutter is first opened immediately before the marking command is received, and then the nozzle is driven by the marking signal. Some means is required to issue a shutter drive command just before the marking signal arrives. Therefore, such a marking device has the disadvantage that the electrical circuit configuration of its control system is complicated. The present invention has been made in view of the above-mentioned circumstances, and provides a marking device that does not require opening the shutter immediately before a masking signal is received and can simplify the circuit configuration of the control system.

The details of the present invention will be explained below based on the drawings.

As shown in FIGS. 3 and 4, the device housing 11, which is formed of a steel plate or the like, has openings 13, 13 on both side walls 12, 12 for the linear object L to pass through, and has openings 13, 13 on the inner surface of the upper end wall. A first solenoid 1A is mounted with the axis of the plunger 15 perpendicular to the inner surface. A pivot shaft 1 having an axis perpendicular to the side wall on a straight line parallel to the axis of the cup plunger 15 and having a sharp end protruding into the housing through the center of the opening of the side walls 12, 12.
6 and 16 are installed. Furthermore, it is preferable that the pivot shafts 17 and 17 are provided at equal distances from the center of the opening with respect to the pivot shaft. It is possible to adjust the position in the axial direction and to fix it in any position. That is, a thread is carved into the pivot shaft 16, and the thread is screwed into nuts 18 fixed to the side wall 12, and a locking nut 19 is threaded onto the thread. . On the other hand, the nozzles 20 and 21 are protruded from the side peripheral surfaces of nozzle heads 22 and 23 which have pivot seats on both end faces}ν, and the nozzle heads 22 and 23 are respectively mounted on pivot shafts 16, 16 and 1.
It is rotatably supported between 7 and 17. Further, each nozzle head is provided with ink supply cylinders 24 and 25 that protrude in the direction 90 with respect to the nozzles 20 and 21, respectively, and link mounting brackets 26 and 27 are provided on the opposite side. The ink supply cylinders 24 and 25 are connected to flexible tubes 28 and 29 that communicate with an ink supply source (not shown) that supplies pressurized ink. Na, nozzles 20, 21
Although not shown, a syringe needle is attached to it. The drive link 31, whose upper end is connected to the plunger 15 via a small link 30, has an arcuate shape that largely escapes the running path of the linear part, and has a nozzle head 22 at the upper end and a nozzle head 23 at the lower end. They are continued by link mounting brackets 26,27.

Furthermore, an adjusting screw 32 is provided on the bottom wall of the casing 11, the tip of which abuts against the lower end of the link 31.

Two guide bars 33 parallel to the running direction of the linear object are movably engaged at positions below the solenoid 14 on the side walls 12, 12, and these guide bars are connected to the second solenoid 34. It is connected via a tie rod 36 to a plunger 35 which is driven thereby. An upper straight portion 37a of a shutter 37 is fixed to the guide bar 33, which is located inside the arc of the drive link 31, and has a shape in which one side of the opening 13 is cut out and two adjacent sides of a regular hexagon are removed. Figure 9: A spring 38 is connected to the guide bar 33 between the inner surface of the side wall 12 and the upper straight portion 37a of the shutter, and the shutter 37, that is, the guide bar 33 is always pushed in the direction in which the flange 35 comes out. The shutter 37 is pressed against the inner surface of the side wall where the solenoid 34 is not installed.

In the device configured as described above, when the first solenoid 14 is inactive, the plunger 15 is in the lowered position, and at this time each nozzle 20, 21 is connected to the link 31 so that its dinites intersect on the closed side of the shutter 37. is connected to.

Also, when the second solenoid 34 is not activated, the shutter 3
7 is pushed against the inner surface of one side wall by the spring 38, and does not exist in the plane where the dinit of the nozzles 20 and 21 is injected. The apparatus of the present invention having the above structure is controlled by a well-known controlled rotation as shown in FIG. 5A.

That is, the marking signal P1 is input to the monostable multi-pipetrator Tl, t2, and the monostable multi-vibrator t! , T2 are the width T as shown in FIG. 3B, respectively.
It generates pulses P2 and P3 of lt2. The pulse P2 energizes the first solenoid 14 for a time t1 via the solenoid driver circuit D1, and the nozzle 20,
Perform 21 swings. On the other hand, the pulse P1 is generated by the polarity inverting circuit R
given to. The monostable multivibrator T3 generates a pulse P4 having a width T3 by the rising v signal obtained (by reversing the polarity of the pulse P3), and closes the shutter 37 for a time T3 after the time T2 has elapsed. The trigrams, markings, needles,
It is desirable to perform this while keeping a predetermined angle with respect to the running direction of the filament.

That is, as shown in FIGS. 6 and 7, the injection needle is set at a required angle with respect to the traveling direction of the filament L in accordance with the linear velocity of the filament L, so that the mark 39 after marking is It is desirable that the line be perpendicular to the axis of the line condition. Further, the above-mentioned marking may be performed by adjusting the electric circuit and identifying the marking as follows.

In other words, for example, if the number of mark signal arrivals is 5,
Marking should be done at a rate of once, and if the length of the filament is 1 m, it will be marked in black, if it is 5 m long, it will be marked in black, if it is 5 m long, it will be marked in black, if it is 10 m long, it will be marked in black.
Mark the filament with red and yellow identification marks so that the size of the filament can be seen at a glance.

In this case, it is necessary to provide a plurality of pairs of nozzle heads depending on the number of identifications. Marking is carried out by the apparatus of the present invention as follows.

In the apparatus of the present invention, when the marking signal is not present, the shutter 37 is not in the plane in which the dinitrite from the nozzles 20 and 21 is jetted. Therefore, when the first renoid 14 is energized and the link 31 is pulled up at the same time as the marking signal is input, the nozzles 20 and 21 swing their heads in the direction across the linear object L, and the linear object L is Marks are applied from the top and bottom. Next, when the nozzle swing reaches its maximum, the second solenoid 34 is energized, the shutter 37 is pulled toward the solenoid against the spring 38, and the dinits of the nozzles 20 and 21 are injected. People come within the area being treated.

The first solenoid 14 is now deenergized and the nozzle 20,
21 returns to the original position shaking his head in the opposite direction from before.

At this time, the dinit is blocked by the shutter 37 and does not reach the linear object L.

Once the nozzles 20, 21 have returned to their original positions, the second solenoid 34 is deenergized and the shutter 37 is pushed back to its original position by the spring 38.

As is clear from the above, in the apparatus of the present invention, the shutter 31 is always open and the shutter blocks the jet when the nozzle returns to its original position after marking. Therefore, there is no need for a special control circuit that opens the shutter immediately before the marking signal is received, unlike the case where the shutter is always closed and opened during marking. Therefore, the circuit configuration of the control system can be simplified.
Furthermore, in the present invention, since the marking is performed by spraying dinit-like ink onto the running filament,
It has the following advantages. That is, (a) since the marking is performed through the nozzle head, the visible mark can be made thinner and its color can be made darker, allowing accurate marking to be performed.

(b) If the linear velocity of the filament is within the range of approximately 5 m/min to 40 m/min, markings without deviation in the axial direction of the filament, that is, markings that are perpendicular to the axis, can be obtained.

(c) Marking can be done without contact, so the mark does not rub or become wide.

(d) Since dinit-like ink is constantly jetting out,
Stable marking can be performed at all times without ink clogging or ink hardening. 0-:=Z groan? It is possible to make high-speed markings, and highly accurate markings can be obtained.
