Marking device for elongated material

The invention relates to methods and an apparatus for marking elongated material with ring-shaped markings. More specifically, concerns the invention the marking or other

Color coding of elongated material as in- jflj

for example insulated wire, as used in telephone and electronic industry is used.

Previous patents on apparatus for performing the same general purpose are shown in FIG U.S. Patents No. 2,865,323; and to Burke et al. No. 3021815. The invention can be regarded as one of these inventions substitute improvement should be considered.

The methods previously described in these patents suffer from a number of disadvantages. For example, they are not easily adjustable to changes. If the distance between the marks is thus changed _Λ

should, the entire marking device must be disassembled

.be built and replaced. In addition, a full set of wheels and drive gears must be ready with 1 sentence required for each possible change desired * Another problem with the previously known devices lies in the change of Color of the ink. If thus a color change is made is to be, the device must be completely emptied of an ink, cleaned and refilled will. This incurs significant labor costs and downtime. Another problem with the previously known Methods lies in the clogging of spray holes during operation. At these facilities will the ink through a large number of spraying

nozzle holes and as described in patent number 2865323, each of these holes must be clean and function properly in order to avoid rejects during production. For this reason, the arrangement of patent no. 3021815 specifically provides a second set of spray holes on each wheel to duplicate the function of the first set. In this way, the 2nd sentence reduces the risk of generating rejects as a result of blockages in the 1st sentence. The problem, however, is that even with the device of Patent No. 3021815, 2 consecutive holes can be blocked and a large amount of defective material can be generated before the operator is aware of it.

Accordingly, it is a general object of the invention to provide an improved marking method and apparatus to accomplish. More specifically, it is an object of the invention to provide an arrangement capable of applying a wide variety of hoop-shaped indicia to an elongated material, without having to change parts, as well as a complete range of marking varieties with the replacement of parts and / or downtime kept to a minimum. Another aim is to create a method and device for complete ring-shaped marking, in which the complete marking is accomplished through a single spray opening. Another task is "in the creation of a method for such marking combined with a device by which triggers an alarm when there is a change in the viscosity of the ink or a blockage opening occurs, making it ineffective or faulty Operation is detected immediately. In fulfillment of this and

other objects of the invention is one more preferred Form of training of the same an elongated. Material such as an insulated wire arranged with a suitable drive mechanism drives this through a marking station. At the marking station there is a spray nozzle together with a device that pumps the ink to it, V7 with the beam pointed at the wire. the The spray device is also provided with a device through which this cross back and forth, so that the ink only during part of the back and forth rub occurs on the wire. In this way, separate markings or identifications are applied to the wire and the distance between the marks is obtained by controlling the relationship between the speed of the reciprocating motion and the stroke of the, " Spray jet as well as the throughput rate of the wire. It is a feature of the invention that an independent control is provided for this ratio and that accordingly the spacing of the marking can be changed at will without the machine apart must be taken. In addition, for a specific ratio of vibration to throughput rate, the distance between the markings can also be influenced within limits by moving the wire to one side of the center line of the stroke.

Another feature of the invention is that the entire circumference of the wire with a band ring-shaped License plate is marked by means of a single spray opening. This is achieved in which the speed of the jet and the viscosity of the ink is regulated so that when the jet passes through a tangent of the Wire to the other the surface tension of the wire a bending of the ink flow around the opposite back

of the wire causes. As soon as the liquid ink unites on the far side of the wire, it continues to flow together and creates an essentially complete band.

Another characteristic of the invention is that there is an effective actuation pump, which ensures that a constant flow velocity through the spray mouth is ensured. To this Way there can be changes in viscosity or in the blockage of the orifice due to changes in pressure in the supply line to the mouth can be discovered. This in turn allows a simple pressure gauge to be used to activate an alarm signal in the event of viscosity increases or blockages.

Additional features of the invention include:

a) a simple flushing arrangement for the ink supply, which allows a quick ink color change without substantial Downtimes are guaranteed,

b) a system that is equally applicable to the simultaneous Application of multi-colored and / or multi-spaced markings,

c) a system that is suitable for vertical or horizontal operation and d) a system through which rotated or braided material can be marked with a tape.

/ 7ie shown in Fig. 2, there are 2 such spray nozzles shown, each consisting of a nozzle 30 and a nozzle 32. The choice of the diameter of the nozzle is dependent of the desired thickness of the current. In this preferred embodiment, the diameters are in Range between 0.013 "- 0.080".

The nozzles 30 and 3 2 are mounted on a vertical jamming base 34, which in turn is attached to a horizontal lever 36 is mounted. The lever 36 allows a sliding horizontal movement in a bearing 38 attached to the platform 12 is attached. The lever 36 is set in reciprocating motion by a motor 40 which has a Crankshaft 42 and a joint 44 that acts at one end of the lever 36 is articulated.

The ink is fed to the nozzles 30 and 3 2 by means of an action pump 46 (piston pump or equivalent pump), which is driven by a motor 48 at a constant speed. The pump draws ink from you Container 50 through line 52 and forces it through line 54 to the nozzles. As shown, the line ends 54 in a T-shaped connection 56, from which an elastic tube 5 8 to the nozzle 30 and an elastic Pipe 60 leads to nozzle 32.

The ink coming out of the nozzles hits the wire intermittently as the nozzles go back and forth and how As shown in Figures 3a and 3b, the surface tension causes the current to flow around the wire and so too wets the opposite side of the wire.

Excess ink is sprayed over the wire and collected in a hood 62 which extends into a sump 64 flows off and from there back into the container 50 through a drain line 66.

As shown, the two strips of tape are applied simultaneously each time the streams of ink from the nozzles pass through the point of impact. Of course, a single nozzle can be used if so desired or different combinations of number and spacing of the nozzles can be used. In addition, differently colored inks can be used simultaneously using a second nozzle or nozzles with the associated devices as described - be attached, which point in different ~ -m directions, so that the 2nd ink stream does not mix with the ink stream of the first nozzle or nozzles.

Viscosity plays a role in the implementation of this process the ink plays an important role, as the surface tension causes the ink to flow around the wire, and form a substantial, complete, annular band. It has been found that a proper viscosity according to the standard viscosity test 'using a No. 2 tooth cup (manufactured by General Electric Co.) at 17 see. + 5 sec. Lies.

Although a straight horizontal movement is shown for the nozzles has been, it should be noted that a circular φ shaped movement - as in Fig. 4 - or a figure-8 movement - as shown in Fig. 5 - also used can come. Indeed, by choosing a given Part of the cycle of such a movement, in which the current is moved along with the wire, is an increased speed. ■ can be preserved.

Although only the movement of the nozzle has been shown, should also be noted .. that instead the wire can be moved or both can be moved at the same time.

Another relatively important aspect is the type of ink flow. The electricity just remains in the range of a few inches smooth and contiguous, after which it dissolves into small drops. With this invention, the best marking effect is obtained as long as the ink flow is still smooth and is together and for this reason the nozzles are about 1 "away from the wire.

Still another feature resides in the hoods 62. Since the ink tends to splash, the hoods must 62 be spaced well from the wire. As shown above, the distance is approximately 12 '".

Since the ink is exposed to the air, it is obvious that that it suffers a loss of volatile components during operation. With the shown Arrangement, this can be detected by a pressure sensing device 68, which is used to distribute the Ink pressure is arranged in the line 54, and / or for actuating an alarm signal 70. Since the motor 48 is a constant speed motor and the pump 46 is an action pump, the behaves Pressure in line 58 directly proportional to viscosity. Also, any blockage in any nozzle results in an immediate change in pressure. The pressure sensing device can be used to actuate the alarm signal 70 for an undesirable increase in viscosity and / or in terms of a blockage of a nozzle. If the viscosity is too high this can be easily corrected by simply adding a solvent to the ink tank 50. To get the drying time To decrease, the wire 14 can be preheated to some extent. However, it has been found that the surface tension by which the ink around the

Wire being pulled around is hampered by excessive preheating of the wire. However, once a given suitable preheating condition is established, the remainder of the drying can take place in the oven 22 before the marked wire is wound onto the take-up reel 24 . ■ ■ -VV ■ - "- ■".-;. ■■■■

The change in ink color in the device was yes The invention takes place by means of a bypass line 72 and valve 74 that from the line 58 into the sump leads. A shut-off valve 76 in FIG Line 5 8. The procedure is such that the valve 74 is opened, the valve 76 is closed and the line 52 is removed from the container 50. With the pump running 46 is the remaining ink in the system below the valve and pumped out in line 7 2 and into the container discharged through the drain line 66. In a short time it will then container 50 removed and replaced by a container replaced with a different colored ink. Line 5 2 will then inserted into the new ink container and the new ink of a different color can be pumped through line 72 for a short time with valve 76 open, valve 74 closed and the pumping of the ink through the nozzles .30 and 3 2 is resumed. For a short time the new color can be mixed with traces of the previous color, but This disappears very soon when the ink runs through the Lines and the ink tank circulates.

An advantage of the viscosity control and the alarm signal according to the invention is that.an ink of much higher viscosity; can be used than with the conventional method because of the risk of accidental Nozzle clogging was eliminated by the invention. In the conventional method, become extreme light inks used to prevent accidental clogging turn off if possible. The result of using
