Description

Finishing plant and method for finishing elongated winding material

The invention relates to a finishing plant and method for finishing elongated, metallic winding material.

Finishing systems and methods for refining elongated metallic winding material are already known.

For example - at least the applicant - a wire finishing system is known in which a basin is provided which is filled with an electrolyte. The pool is open at the top. A wire to be refined is fed into this basin from above, deflected several times in an electrolyte-filled area within the basin, deflected and led upwards out of the basin. Power rails are arranged within the basin. In the longitudinal as well as in the transverse direction, the interior of this pool is limited by plastic walls. On the outside, these plastic walls are surrounded by a steel frame that serves as a reinforcement. In this design known to the applicant, for cleaning or depositing the electrolyte, it is pumped out of the basin into a container, provided with flocculant there, left for some time and then pumped back into the basin.

The invention has for its object to provide an efficient, inexpensive and reliable refining system for elongated, metallic winding material, and an efficient, inexpensive and reliable method for refining elongated, metallic winding material.

The guide and container system can be such that the wire is moved into and out of the same container several times during operation, and / or such that the wire is moved into a loading area. container of the container system is brought in and out of this and then in another container of the container system and out again. A combination of these designs is also preferred. These containers are preferably channels, in particular those that will be described elsewhere in this disclosure.

The object is further achieved by a finishing plant according to claim 6.

According to the invention, in particular a wire finishing system is provided with a container system which, or its container, can be filled with an electrolyte and is in operation of the system. This container system has several channels that are separate from one another. These different channels are run through by the same wire during operation of the system, if necessary several times.

The channels preferably have a U-shaped cross section. The channels are made of plastic or another suitable material.

The guide system can have drive rollers and / or deflection rollers. In particular, it is provided that a part of such rolls is electrically conductive, has a contract with an electrical power connection and conducts an electrical current to the wire guided over this roll.

Such a basket is provided with hooks or other contact elements which are brought into contact with a busbar during operation. These elements can be made of copper or another suitable, electrically conductive material. The busbars are made of copper or another suitable electrically conductive material.

The pallets can be made of tin or a different material depending on the finishing layer.

In a preferred embodiment, the channels are provided with side walls in their end regions positioned in the longitudinal direction. These can, but do not have to, form the lateral end of the respective channel.

Such side walls preferably have openings through which the wire can extend in each case and extend during operation of the installation in order to be moved out of the respective channel or into the respective channel.

Such openings can be slit-shaped or in some other way.

In a preferred embodiment, a wire finishing system according to the invention has a container system with a plurality of channels spaced apart from one another. In principle, these can be spaced apart in any direction. It is particularly preferably provided that the channels are spaced laterally. Channels can also be arranged at different heights with respect to the subsurface.

It is further preferred that the channels are arranged parallel to one another.

In the case of such preferred designs with a plurality of spaced-apart channels, it is particularly preferably provided that different channels are connected via a channel, such as a tube, in order to enable electrolyte volume compensation or level compensation. In a preferred embodiment of a wire finishing system according to the invention, it is provided that in the longitudinal direction of the at least one channel there is a container on both sides of the (electrolyte) container system, which is used to hold deflection and / or drive and / or current rollers for the Wire and / or for receiving electrolyte emerging from the channels.

Such a container, which differs from the (electrolyte) container system, is preferably arranged in such a way that the channel can expand essentially freely in the longitudinal direction in the manner already described.

In a preferred development of the invention, such a container, which differs from the (electrolyte) container system, is sealed off from the respective channel of the (electrolyte) container system. Such a seal is preferably designed in such a way that the sealing effect is also given when the channel is elongated. For example, a U lip seal can be provided.

In a preferred embodiment, sealing devices are provided in the side walls of the channels, which enable wire to be moved through side channel walls, this side wall being essentially sealed in the area of the passage.

It is also preferred that an intermediate wall is provided in the channel, which divides the channel into a space which is to be filled with electrolyte or in which an electrolyte bath is to be provided or is provided during operation of the system, as well as a different one Room. In this case, openings can be made in this intermediate wall and / or in the wall of the essentially electrolyte bath-free space opposite this wall. gene provided through which the wire can be moved or is in operation.

In a preferred design, the essentially electrolyte-free space is a space that is different from the channel.

In a preferred further development of these designs, a further container different from the container system is connected to ends located in the longitudinal directions.

In these designs, it is preferably provided that openings are provided in all walls lying in the longitudinal direction, through which openings the wire can be moved.

It is preferably provided that - viewed from the center of the channel - two, three or more openings with openings are provided in one and / or both orientations of the channel direction through which the wire can be moved. Such walls can be arranged inside the channel and / or channel-limiting or outside the channel. Walls which are arranged outside the channel can be, for example, those which limit a container which directly or indirectly adjoins the inner longitudinal section and which are different from the container system. It is particularly provided here that the individual walls in the area of the wire passage are not liquid-tight and that this wall arrangement is effectively liquid-tight in its interaction.

This design is to be explained in more detail using a specific example, which is not intended to be restrictive: for example, a wall closer to the center of the channel can have an opening through which the wire can be moved in an area which, in operation, is on the side facing the center of the channel is below the electrolyte level, which is given m the channel. Not only can the wire be moved through this opening but also flows part of the electrolyte. In this room, into which the electrolyte flows and which can also be designed like a shaft, an opening is provided in the floor area or in the lower area of the side walls of this room, through which this electrolyte is discharged from this room. This opening is optionally arranged on a suction side of a pump. The wire is moved through this space and leaves it through an opening in a wall, which is - in this respect - opposite the intermediate wall and also has an opening of the type described above. However, since the filling level of this essentially electrolyte-free space does not reach this opening despite the penetrating electrolyte - since the electrolyte is discharged from the room through another, lower-lying opening - essentially no fluid penetrates to the outside through this opening. Due to the distance and / or the design and / or the number of such walls arranged in series, the sealing effect of this unit can also be designed in such a way that it is essentially ensured that no splash water or electrolyte can escape to the outside. Such a design can be given regardless of the direction of wire movement.

It should be noted that the wire can be led out of the container system and / or the unit of container system and containers different from this on the side on which it is also introduced or on another, for example the opposite one.

In a preferred embodiment, sealing strips with an oblique rim opening are provided as or in the intermediate and / or side wall of the channel and / or a container adjoining it. These can in particular be designed in such a way that a liquid stream penetrating this wall is conducted away from the wire. It is also preferred that, instead of such a design, at least one comb-like hinged sealing strip is provided in the intermediate wall. This can be such that two comb-shaped parts are overlapped on top of one another and the wire can be moved through the gaps that form in the process.

The wire is preferably passed over electrically conductive current rollers which are arranged outside the container system and, if appropriate, additionally act as deflecting rollers. Such current rollers can also be driven by a drive device. These flow rollers are preferably arranged in a container which adjoins the channels directly or at a distance in the longitudinal direction of the channel.

In a preferred embodiment, a basket for receiving metallic pellets or an anode is provided which has at least one contact support arm, via which the anode or the basket can be supported in an electrically conductive connection on a busbar. Such a contact support arm can also be designed as a hook. It can be such that the anode or the basket can be hung in the rail or in such a way that it can be placed on the conductor rail via it; but other designs are also possible. Such a contact support arm can be made of copper or another electrically conductive material.

In a preferred embodiment, a basket for holding metallic pellets or an anode is provided which, in the case of the basket, arranged in the outside of the basket interior, has tabs projecting outwards or in contact support arms, a slot which leads to one of the basket wall or the Anode spaced outside of the tab or the support arm is open. Such a basket can - like the one described above with contact support arm - be given in a system according to the invention be or for receiving pallets as well as for a wire finishing plant. The applicant reserves the right to request isolated protection for such a basket. In further developments, such a basket can also have additional features that are described in relation to a basket in this disclosure.

In a preferred embodiment of the invention, a wire finishing system has a transport device driven by a drive unit, which can accommodate an anode or a basket - and in particular a basket of the aforementioned design - and position and remove this anode or this basket in the wire finishing system in its operating position this can remove.

In a particularly preferred design, the anode or the basket has one or more slots of the type described, the transport device having arms which can be moved into the respective slot in order to reach behind the tab or the contact support arm from below in this position ,

The containers of the container system preferably have one or more inlets via which electrolyte can be introduced into the container system. These can be provided, for example, in the bottom or a wall of the container or the channel, in particular near a side wall opening through which the wire is or is to be moved into this container. For example, two inlets can also be provided in this area, one of which is arranged on the left and the other on the right of the moving wire. The most varied of variants are possible for the arrangement and number of such inlets.

It is also preferred that electrolyte drains are provided in the bottom or a wall of the channel. A power connection is preferably provided on the busbars essentially in the middle, specifically in the longitudinal and / or transverse and / or vertical direction.

A preferred wire finishing system has a settling system with two settling containers different from the container system. For example, this can be such that the first container of the settling system is connected to the container system via a first channel and to the second container via a second channel. The second container can be connected to the container system via a third channel. The mode of operation is preferably such that the electrolyte is pumped out of the container system and the pumped-off electrolyte in the container system is essentially replaced by "fresh" electrolyte. This "fresh" electrolyte was previously subjected to a settling process and the electrolyte pumped out of the container system was pumped out to be subjected to such a process. It should be noted that the number of containers can in principle be increased as desired. Such further containers can be connected in series or in parallel. It can further be provided that the respective channels can be closed and opened.

The wire finishing system preferably has a filter system for filtering the electrolyte. The electrolyte is particularly preferably cleaned by means of a filter system.

The cleaning of the electrolyte by means of such a filter system can take place, for example, at the same time or with a time shift for settling.

However, a settling device can also be provided without a filter device being additionally provided, or vice versa. In a preferred embodiment, the wire finishing system has a pallet loading system which can load the baskets with pallets automatically or semi-automatically during operation of the system.

In a preferred embodiment of the wire finishing system, at least one current roller driven by a drive is provided, which can conduct an electrical current into the wire and has a drive that can be folded away during operation. To fold away, a coupling may have to be released beforehand. It can be folded away, for example, for assembly or cleaning purposes.

In a preferred embodiment of the invention, one or more busbars and / or at least one basket made of electrically conductive material, which may be filled with metallic pallets, and / or an anode and / or a container system with one or more channels are provided, each of which in particular can be designed and / or arranged as described elsewhere in this disclosure.

The object is further achieved by a method according to claim 27.

The invention is not intended to be limited by the exemplary and preferred designs. Some aspects and preferred aspects of the invention will now be explained in more detail below with reference to the figures, although this is not intended to limit the invention.

1 shows an exemplary wire finishing plant according to the invention, in which a method according to the invention can preferably also be carried out.

The wire finishing system 1, which is shown in partial view in FIG. 1, has a support structure 10 and a container system 12 which is hidden in FIG. 1 and which is explained in more detail elsewhere.

Furthermore, the finishing system 10 has containers 14, 16 which are different from the container system 12.

The container system 12 is covered by a second cover in the form of a lid 18. These covers 18 can be opened and closed and are shown in a closed position in FIG. 1.

Furthermore, covers 20 and 22 are provided which cover the containers 14, 16 and can also be opened.

FIG. 2 shows the design according to FIG. 1 in a partial view, the covers 18, 20, 22 in FIG. 2 being removed.

The container system can be seen in FIG. 2, which has a plurality of channels 30, 32 which are supported on the support structure 10. These channels are spaced apart. In Fig. 2, this is designed so that the channels are arranged in parallel with a lateral distance from one another.

Outside of these channels, busbars 34, 36, 38 are arranged, which are connected to a power connection, not shown. In operation, the channels 30, 32 are filled with an electrolyte. These busbars are made of copper.

Furthermore, in operation baskets 40, 42 m are arranged in the channels 30, 32, which are made of titanium and are supported on the busbars by copper hooks 46, 48 or are suspended there.

In operation, metallic pallets, such as tin pallets, are arranged in these baskets 40, 42. However, these pallets can also consist of another metallic material.

The channels 30, 32 have side walls 48, 50, 52, 54 arranged in the longitudinal direction, in which openings 56, 58, 60, 62 are arranged.

These openings can be slots or holes or be designed in some other way.

These openings serve in particular so that the wire, which is indicated schematically in FIG. 2 by the dashed line 64 and is to be finished, can be led out and in from the containers 30, 32.

These openings are preferably, which is not shown in FIG. 2, sealed by suitable sealing devices in such a way that the wire can be moved through these openings, but if possible, electrolyte does not escape. In this context, it should be noted that it is also possible, however, to consciously allow the electrolyte to flow away, in order, for example, to enable an electrolyte exchange in cooperation with a, in particular continuous, electrolyte supply.

The channels 30, 32 are connected to one another via a pipe connection, which is shown in FIG. 2, in order to enable an electrolyte exchange. Electrolyte exchange means in this sense that electrolyte to and fro between the channels 30, 32 can flow to achieve a volume exchange or a filling level adjustment. In the aforementioned sense, on the other hand, electrolyte exchange means that the electrolyte, in particular in a continuous process and during operation, can be exchanged for a "fresh" or cleaned electrolyte.

Fig. 2 also shows a roller 66, which has the function here as a current roller and as a deflection roller, and can also serve as a drive roller. Current can be transferred to the wire via this current roller. This roller 66 is arranged in the container 14. Such a roller is also located in the container 16.

It should be noted that a plurality of such rollers can also be provided in the containers 14, 16. In a preferred embodiment, the wire is guided through the channels 30, 32 and over the rollers 66 in such a way that several wire layers are spaced one above the other. In the case of such a design, the wire course can be such that it is guided essentially approximately to an elliptical spiral.

FIG. 3 shows a three-dimensional view of the design according to FIGS. 1 and 2, partially cut open in the longitudinal direction.

In FIG. 3 it can be seen in particular that the channels 30, 32 have a U-shaped cross section.

The channels 30, 32 are in particular made of non-metallic material and can be made of plastic, for example.

3, first covers 80 and intermediate covers are also shown. These intermediate covers 80 are designed so that they partially cover the channels upwards and leave a gap through which the channels or the baskets 40, 42 located in the channels can be loaded with pallets, even during operation.

Between these intermediate covers 80 and the cover 18 there is an intermediate space 82 which is essentially free of electrolytes. This intermediate space 82 can also lie outside the channels 30, 32. However, it can also partially lie within these channels, although this is not shown in FIG. 3.

Furthermore, an extraction system, not shown in FIG. 3, is provided, which can extract vapors, such as acid vapors. In a preferred embodiment, a suction opening is arranged below the intermediate cover, that is, it projects into the channel 30 or 32.

Fig. 4 shows a partially sectioned side view of the wire finishing system 1 in a partial view.

It can be seen in FIG. 4 that the titanium baskets 40, 42 are hooked into the copper rails 34, 36, 38 via their copper hooks 44, 46.

4 that the channels 30, 32 are spaced apart and arranged in parallel.

FIG. 5 shows an exemplary embodiment of the invention, which is essentially or can be as that described with reference to FIGS. 1 to 4.

5 differs from the aforementioned in that an intermediate wall 90, 92 is provided in each of the channels 30, 32. This intermediate wall 90 or 92 has an opening 94 or 96 through which the wire can be moved.

This opening 90 or 92 is each designed as a slot in the design according to FIG. 5, but can also be designed differently.

In the design according to FIG. 5, it is provided that this intermediate wall 90, 92 divides the channel 30 or 32 into a first room 98, 100, which is to be filled with electrolyte, and on the other hand into a second room 102, which is designed is sealed off from the first space 98, 100 and, in a further embodiment, is designed in such a way that certain amounts of electrolyte from the first space 98, 100 penetrate into this second space 102, 104, but not so that it reaches the same filling level as the first space 98, 100. If appropriate, additional devices are provided in this area which reduce the inflow of the electrolyte from the first space 98, 100 into the second space 102, 104, such as comb-like sealing strips.

A drain can also be provided in the floor or in the lower side wall region of this second space 102, 104, through which the electrolyte flowing in this second space 102, 104 is discharged and, if appropriate, is returned or pumped back into the respective first space 98, 100.

It should be noted that the second space 102, 104 in the design according to FIG. 5 is arranged inside the grooves 30, 32, but it is also preferred that a container different from the groove or a space 102, 104 lying outside the groove additionally and / or alternatively.

6 shows an exemplary design of an intermediate wall 90, 92 which can be provided within the channel 30, 32, 5, or which can be provided as a side wall 48, 50, 52, 54 of a channel 30, 32.

The intermediate wall 90 has an opening 94 which can extend over a section in the height direction of the wall or over the entire height of this wall.

The partition wall separates a first room 98 from a second room 102.

In the area of the sealing strip or intermediate wall 100, a bord mouth 110 is provided, which is designed such that the projecting wall regions 112, 114 of the bord mouth 110 extend in the direction of the first space 98. These wall areas 112, 114 are arranged at an angle to one another. During operation, the wire can be moved through the opening 94 between these wall regions 112, 114, in particular in such a way that this wire is moved in the longitudinal direction of the channel 30.

In the design according to FIG. 6, the first wall section 112 of the rim opening 110 is oriented essentially parallel to the longitudinal direction of the channel 30, while the second wall section 112 of the rim opening runs at an angle to this longitudinal direction, in particular in such a way that the free end 116 this second wall area 110 is arranged facing the opening.

The second wall area 114, which runs obliquely to the wall along which the wire 64 is to be moved, projects further in the direction of the first space 98 than the first wall area 112.

Such a design of a mouth of the bord, which is mentioned purely by way of example, can result in electrolyte passing from the first space 98 into the second space 102 in the second Space 102 is directed away from the wire, as schematically indicated by lines 118, 120.
