Description

The present invention relates to a method for producing a textile material strand for treating a wire and to such a textile material strand.

In addition, the present invention relates to a method for treating a wire with an active substance, comprising the steps of providing a textile material strand impregnated with the active substance, providing a wire to be treated with the active substance, engaging the textile material strand with the wire to be coated, so that a process zone is formed becomes, in which the textile strand of material and the wire to be treated are engaged with each other, and performing a relative movement between the textile strand of material and the wire to be treated in the process zone.

Moreover, the present invention relates to an apparatus for treating a wire with an active substance with a supply reel with a textile material strand impregnated with an active substance, a feed device for feeding the textile material strand, a feed device for supplying a wire to be treated with the active substance, a process zone a device for engaging the textile material strand with the wire to be treated and a drive device for generating a relative movement between the textile material strand and the wire to be treated in the process zone.

Wires for very different applications are often made after their manufacture, i. after forming the wire of metal or other material, reworked, for example, by being cleaned and / or coated on its surface in order to modify and improve the surface properties of the wire in a targeted manner.

To clean or coat the wires, methods are known in which the wire is brought into engagement with a textile strand of material, usually the textile strand of material wraps around the wire at at least one location, and then the wire and the textile strand of material relative be moved to each other. The relative movement between the wire and the textile material strand has the effect that active substances can be transferred from the textile material strand onto the wire and that a fresh section of the textile material strand is always available in the region of the loop without contaminants and / or with fresh active substance.

A device for cleaning a wire in such a way, for example, from DE 10 2005 037 159 A1 known.

In order to apply a coating to a wire or to increase the cleaning effect of the textile material strand, textile material strands are used, which are completely impregnated with an active ingredient. Examples of such agents are, for example, oils as lubricants or detergents and abrasives for cleaning the wire. The transition of the active ingredients from the textile material strand to the wire surface takes place in the process zone either by the friction between the wire and the textile material strand or by an additional heating of the process zone.

Compared to this prior art, it is an object of the present invention to provide a method for producing a textile material strand, a textile material strand and a method and an apparatus for treating a wire with at least one active ingredient, which allow an improved treatment of the wire. In addition, it is an object of the present invention to provide a method for producing a textile material strand, a textile material strand and a method and a device for treating a wire, which allow an improved effect of at least one active substance on the wire in the process zone.

At least one of the foregoing objects is achieved by a method of making a textile strand of material comprising the steps of: providing a first fiber or filament, introducing or applying a first agent into or onto the first fiber or filament, providing a second fiber or a second thread, joining the first fiber or the first thread and the second fiber or the second thread to the textile material strand.

In one embodiment of the invention, no active substance is introduced into or applied to the second fiber or the second thread of the textile material strand. A textile material strand produced in this way makes it possible to apply a well-dosed amount of the first active ingredient to a dirty or soiled wire. In this case, the second fiber or the second thread without active ingredient serves to clean the wire, while the active substance is transferred from the first fiber or the first thread to the wire. The fiber or non-drug thread, in one embodiment, picks up the debris from the wire and prevents the entire textile strand of material from becoming contaminated, which would worsen the transfer of the active ingredient from the textile strand of material to the wire.

In another embodiment, the method additionally comprises the steps of introducing or applying a second active substance into or onto the second fiber or the second thread, wherein the second active substance is different from the first active substance.

A textile material strand produced in this way, which is composed of a plurality of individual fibers or of a plurality of threads, makes it possible to equip the textile material strand with two different active ingredients which can not be dissolved together and / or which are not miscible with one another are.

While the strand of material produced by the method according to the invention preferably has two active ingredients, this does not exclude that it has more than two active ingredients.

In this way, the possibility of a single textile strand of material results in a plurality of mutually different active ingredients to be transferred to a wire to be treated.

While an embodiment is conceivable in which all threads or fibers of which the textile material strand is composed are each impregnated with an active substance, in one embodiment the textile material strand has at least one first fiber or a first thread with a first active substance, at least one second fiber or a second thread with a second active ingredient and a third thread or a third fiber, in or on which no active ingredient is applied or applied on. Such an embodiment combines the advantages of an embodiment with at least two threads or fibers impregnated with two different active ingredients and an embodiment in which at least one of the fibers or threads is not impregnated.

When it is mentioned in connection with the present invention that a textile material strand is to be used, the term of the textile material strand has the broadest possible meaning, which results for the skilled person from the term "textile". In particular, it comprises textile-like materials. Textile strands of material are, for example, woven, knitted, knitted, crocheted and at least two strands of material obtained from other textile-producing processes. In addition, the term of the textile material strand also includes nonwoven materials in which individual fibers or monofilaments, for example, by heat, moisture or mechanical action, are joined together.

Thus, the term of the textile material strand also includes binders interconnected with fibers or filaments, in particular natural fibers, synthetic fibers, metal fibers, glass fibers, ceramic fibers, staple fibers (short fibers), plastic films and similar materials which have the required properties for the intended use according to the invention, such as, for example, tear strength, resistance to rubbing through, absorbency, linting and other properties.

Based on the knowledge of the required properties and the properties that certain substances or substance combinations have, the skilled person is able to produce and acquire materials for the fibers or threads of the textile material strand produced according to the invention.

It is important to consider the purpose of the process in detail, as in certain cases the textile strand may need to be receptive or absorbent to contain a liquid or solid active such as a lubricant, polish, abrasive or cleaning agent and in the process zone to deliver to the wire. In other cases, the material of the textile material strand itself may have the desired properties and then need not have a capacity to receive and bind, for example, an abrasive agent.

Viscose or cotton is particularly suitable as material for the individual fibers or threads on which the textile material strand is based.

By incorporation or application of an active substance in or on a fiber or a thread, in particular impregnation of the fiber or of the thread is understood.

In this case, in one embodiment, the joining can be effected by stranding the first fiber or the first thread and the second fiber or the second thread, so that the textile material strand is a rope.

In an alternative embodiment, the joining takes place by interweaving the first fiber or the first thread and the second fiber or the second thread with at least one third thread or a third fiber, so that the textile material strand is a mesh.

In this case, an embodiment of the invention is expedient in which at least the first thread or the first fiber with a first active ingredient and / or the second thread or the second fiber with a second active ingredient is a Zettelfaden of the braid, while the Klöppelfäden the braid preferably from another Threads or fibers are formed without active ingredient. This proves to be advantageous because the lathing threads are subject to a lower tensile stress than the bobbin threads and thus the active ingredient is not removed from the fiber or thread during braiding.

In one embodiment, such a braid consists of at least four threads or fibers, namely the first thread or the first fiber on or into which a first active substance is applied or applied, as a leash thread and at least three other threads or fibers which are used as bobbin threads intertwined with each other.

In one embodiment of the invention, the first or first filament and second or second filament are interwoven with a third or third filament such that the filament is a braid having a rectangular cross section, i. a band braid, is.

It has also proven to be advantageous if the textile material strand has in one embodiment at least seven fibers or threads of which it is composed. Even if one of these individual fibers or individual threads breaks, this does not lead to a tearing of the entire textile material strand.

Also advantageous has turned out to be an embodiment in which the woven textile material strand has at least ten bobbin threads and at least three Zettelfäden, preferably exactly 13 bobbin threads and exactly 6 Zettelfäden, wherein in or on at least one of the Zettelfäden an active substance on or applied is.

For the purposes of the present invention, active substances are, for example, lubricants (for example organic lubricants such as paraffins, waxes, oils, fats and stable solutions or mixtures thereof), soaps, corrosion inhibitors, antioxidants, anti-adhesion agents, adhesion promoters, arc stabilizers, cleaning agents or wear protection agents.

In one embodiment of the invention, the active ingredient contains a mixture of a (methyl 12-) hydroxystearate and a paraffin.

In another embodiment, the active ingredient is provided with an additive for corrosion protection of the wire.

In another embodiment, the active ingredient additionally or alternatively an additive for an arc stabilization for a welding wire. For arc stabilization, particularly soaps of the first and second main groups of the periodic table of the elements and sulfur-containing compounds prove to be advantageous as additives.

In a further embodiment, the active ingredient additionally or alternatively contains a metal-organic additive as a wear protection agent. For example, organic molybdenum compounds have proved to be advantageous.

Particularly suitable as a wear protection center are those active ingredients which have proven themselves as engine oil additives for wear protection in engines.

According to one embodiment of the present invention, at least one of the active ingredients, with which the textile material strand is impregnated, can be extracted with the aid of a liquid extractant to be introduced into the process zone.

At least one of the above objects is also achieved by a method of treating a wire having at least two active agents, comprising the steps of: providing a textile material strand provided with a first and a second active substance as described above, providing one with the wire to be treated, engaging the textile strand of material with the wire to be treated so as to form a process zone in which the textile strand of material and wire to be treated engage with each other, effecting a relative movement between the textile strand of material and the wire to be treated the process zone and introducing a liquid extractant in the textile material strand in or before the process zone, which is designed such that it extracts at least one active ingredient from the textile material strand so that it is transferred to the wire to be treated.

This method according to the invention makes it possible to detach at least one of the active ingredients, with which the textile material strand is impregnated, with the aid of an extractant and to apply this to the surface of the wire or to transfer it to it. The transfer of the active substance from the textile material strand to the wire to be treated is thus improved over a carry which is caused solely by the friction between the textile material strand and the wire, and provides a simpler and more effective realization than the additional input of heat in the process zone.

However, in one embodiment of the invention, the extraction of the active ingredient with the aid of an extractant from the textile material strand is supported by the frictional heat between the textile material strand and the wire to be treated, and the uniform transfer of the active substances from the textile material strand to the wire surface is promoted. In addition, in one embodiment of the invention, if appropriate, the process zone can be heated by a further heat source.

While it is advantageous if both active ingredients are dissolved out of the textile material strand with one or more extraction agents, embodiments are also conceivable in which only the first active substance is dissolved out of the textile material strand with an extractant, while the second active ingredient is removed, for example, by the frictional heat of the textile material strand is transferred to the wire.

It is understood that with the method according to the invention in one embodiment, more than two active substances from the textile material strand can be transferred to the wire to be treated.

For the purposes of the present invention, a wire is understood in particular to mean a flexibly shaped piece of material, preferably of metal or plastic, whose diameter is small in relation to its length. Such wires are preferably wound on rolls, spools, reels or spindles. For the purposes of the present invention, wires are also understood to be tubular, so that they have a cavity extending over the entire length of the wire in their interior.

With one embodiment of the method according to the invention and of the device according to the invention, wires can be treated for a multiplicity of applications and of a multiplicity of materials. Examples of such wires are wires and strands of steel, aluminum and copper. These can be used in particular as welding wires or for the manufacture of insulated electrical lines or the like. Embodiments of the invention are particularly suitable for higher quality wire products, which may justify higher costs for the production of the wire.

Thus, in one embodiment of the invention, the extractant used is a mineral spirit or a branched aliphatic hydrocarbon, e.g. Isododecane, used.

In one embodiment, the extractant used must be able to release the active ingredients from the textile strand and transfer them to the wire under the conditions prevailing in the process zone at elevated temperature due to the inter-strand friction. The increased temperature can then also create solutions that would not be stable under normal (cold) conditions.

If in the context of the present invention, it is mentioned that a liquid extractant is introduced into or in front of the process zone in the textile material strand, this means that the liquid extractant and the textile material strand of the process zone on separate Because of being supplied and wetting or impregnation of the textile material strand with the liquid extraction agent takes place only immediately before or in the process zone.

In particular, the liquid extractant is fed by means of a hose to the process zone.

The engagement of the textile material strand with the wire to be treated in the context of the present invention takes place in one embodiment in that in the process zone, i. in the region of contact between the wire to be treated and the textile material strand, at least one loop of the textile material strand is formed around the wire to be treated.

In one embodiment of the invention, the direction of movement of the textile material strand in the process zone is opposite to the direction of movement of the wire.

In this case, the relative speed between the textile material strand and the wire in the process zone is constant in one embodiment.

The relative movement between the wire and the textile material strand in the process zone is realized in particular by moving both the wire and the textile material strand. In one embodiment, the absolute speed of the textile material strand in the process zone is less than the absolute velocity of the wire in the process zone.

In one embodiment, the active agent is applied to the wire, i. the wire is coated with the drug. An example of this is that a lubricant is applied to the wire.

In another embodiment, the active ingredient is selected to clean the wire. It should be emphasized that even the textile material strand itself can cause a cleaning of the wire regardless of the chosen active ingredient.

Such a cleaning action of the textile material strand takes place in particular in the case of an opposite movement of the textile material strand and of the wire in the process zone.

At least one of the above-mentioned objects is also achieved by a textile material strand for treating a wire with at least one first fiber or a first thread and at least one second fiber or a second thread with a second active substance the first fiber or the first thread and the second fiber or the second thread are connected to the textile material strand and wherein the first fiber or the first thread is impregnated with a first active substance and the second fiber or the second thread is impregnated with a second active substance , In this case, the first and the second active ingredient are different from each other.

Likewise, at least one of the above-mentioned objects is achieved by providing a device for treating a wire with two active substances, which comprises a supply reel for a textile material strand with two active substances, as described above, a feed device for feeding the textile material strand, a feed device for feeding a wire to be treated with the active substances, a process zone with a device for engaging the textile material strand with the wire to be coated, a drive device for producing a relative movement between the textile material strand and the wire to be treated in the process zone and a metering device for Introducing a liquid extractant for the active ingredient in the textile material strand in or before the process zone.

The drive device of the device according to the invention causes a relative movement between the wire to be treated and the textile material strand, said relative movement by a movement of the wire to be treated or the textile strand of material and by a simultaneous movement of the wire to be treated and the textile strand of material, but at different speeds or can be effected with different directions of movement.

In one embodiment of the invention, the drive means in the context of the present invention, for example, a reversible in the direction of rotation, in particular variable-speed motor or a stepper motor.

The feed devices for the wire to be treated and for the textile material strand may in one embodiment comprise guides, in particular guide rollers. However, embodiments are also conceivable in which a feed device, in particular for the wire to be treated, is merely formed by corresponding recesses in the device, wherein the device may not even engage with the respective strand under certain circumstances.

In one embodiment of the invention, the device for engaging the textile material strand with the wire to be coated is a belt unit which guides the textile material strand circumferentially one or more times around the wire to be treated, so that during the execution of a relative movement between the wire to be treated and the textile material strand with each surface portion of the treated Wire comes in both the longitudinal and in the circumferential direction at least once engaged.

In one embodiment of the invention, the metering device for introducing a liquid extractant for the active substance into the textile material strand is a combination of a reservoir for the liquid extractant, a feed line and a pump, preferably a gear pump, which delivers the extractant metered to the textile material strand.

It is particularly expedient if the device according to the invention has a control which controls the speed of the textile material strand and the speed of the wire to be treated as well as the dosage of the liquid extractant to be introduced into the textile material strand.

Insofar as aspects of the invention are described in this application with regard to the textile material strand, these also apply to the corresponding process for its production and vice versa. As far as the method according to the invention for treating a wire is carried out with the device for treating a wire according to the invention, it has the corresponding devices for this purpose. In particular, embodiments of the apparatus are suitable for carrying out the described embodiments of the method.

Further advantages, features and applications of the present invention will become apparent from the following description of an embodiment and the associated figures.

FIG. 1 schematically shows an apparatus for treating a wire with a method according to the present invention.

The representation in FIG. 1 shows the course of the textile strand of material T and the wire to be treated in the illustrated embodiment of a welding wire D. In the Garnabzug 4 of the textile strand is withdrawn from one or more supply coils 4.1 and guided via the brake 4.2 to the drive block 2 for controlling the strand bias. There, the strand T is passed over a pulley 2.7 on the drive roller 2.2 and placed to avoid slippage several times to this and the other roll package 2.3.

The drive roller 2.2 and the roller package 2.3 form a mechanical unit in the form of a dancer acting against a spring 2.5. Its deflection is detected by a sensor 2.6 as a strand bias. The actual phase bias voltage is compared with a user-settable desired value. If the actual value is too high or too low, the speed of the Drive motor 2.1 increases or decreases. Subsequently, the strand T is deflected via the stranding pulley 3.2 at a shallow angle parallel to the wire D into the looping or processing zone 3. The wire D runs between two pairs of guide rollers 3.4 and 3.5 of the movement of the textile material strand T opposite. Between the stranding pulley 3.2 and a strand deflection roller 3.3, the two strands T, D are guided substantially parallel to one another, wherein the textile strand T wraps around the wire strand D.

In order to ensure the wrapping of the wire D through the textile strand T, the textile strand T is guided around strand deflection rollers 3.1.1, which are arranged on a belt unit 3.1. The belt unit 3.1 with the strand deflection rollers 3.1.1 is rotatably mounted about the longitudinal axis of the wire D (indicated by the arrow in FIG FIG. 1 ), so that when setting up the machine by turning the Umschlingungseinheit 3.1 around the longitudinal axis of the wire D, the wrap can be achieved. In this way, the textile strand T between the stranding pulley 3.2 and the strand deflection roller 3.3 runs so that it wraps around the wire in this area. As the number of wraps increases, friction between the strand and wire increases, based on the operator-adjustable strand bias. At the strand deflection roller 3.3, the used strand is again deflected away from the wire at a shallow angle and guided to a drive unit 1 for regulating the strand speed. In the drive unit 1, the strand T is again laid several times around a drive roller 1.2 and a roller package 1.3 to avoid slippage. With a drive motor 1.1, the strand is constantly advanced with the speed set by the operator in the device control. The drive roller 1.2 and the roller package 1.3 form a mechanical unit in the form of acting against a spring 1.5 dancer. Its deflection is detected by a sensor 1.6 as a strand tension behind the belt 3. This strand voltage behind the belt 3 is compared in the main unit 5 with a user-adjustable target value and evaluated for a fault alarm.

Subsequently, the strand passes through another deflection roller 1.7 the dancer unit for the winding 5.1, which turns on and off the motor 5.8 of the waste coil 5.9 to maintain a nearly constant strand voltage. With a motorized laying unit 5.5 or 5.7, the strand T is distributed uniformly over the width of the waste coil 5.9.

In the illustrated embodiment, the textile material strand T is a band mesh having a substantially rectangular cross section. The braid itself is braided from 13 monofilaments, of which 6 threads are preimpregnated with a drug of a mixture of a (methyl 12) hydroxystearate and a paraffin having a melting range of between 50 ° C and 60 ° C. This active ingredient, when applied to the welding wire D to be treated, serves as a lubricant for the same. In addition, the mixture is with aggregates as corrosion protection for the welding wire D, an additive for arc stabilization of the welding wire D and a metal-organic additive as a wear protection agent for the guidance of the welding wire D provided.

In order to transfer the active substance according to the present invention from the textile material strand T to the welding wire D, the active substance is extracted or extracted from the textile strand T with the aid of an extractant in the process zone 3.

For this purpose, the second end 19 of a fluid connection 18, in this case a hose, is provided in the looping zone 3 between the stranding pulley 3.2 and the strand deflection pulley 3.3, more precisely in the embodiment shown here between the pulley 3.2 and the strand deflection unit 3.1. This tube 18 serves to supply the extractant from the dosage unit 20 to the textile strand T. The extractant is taken up by the textile strand T and extracts the pre-impregnated active substance out of this, so that it is transferred to the wire D to be treated. In the embodiment considered here, the extractant is liquid paraffin with a large hexane content. This triggers the mixture of the active ingredient described above well out of the textile strand T.
