Description

Field of engineering

The present invention relates to a device for the lateral guidance of a running on a metal belt conveyor metal strip comprising at least one base module with management level and at least one wear body with Schleißfläche.

State of the art

In the production of metal strips, these are conveyed by means of metal belt conveyors, for example roller conveyors, to processing machines, for example reels, where they are wound up. It is necessary to subject the metal bands of a lateral guide. Especially before the start of winding this is necessary in order to keep the offset of the individual windings on the wound coil as low as possible in order to achieve a uniform side surfaces. Devices for lateral guidance are called, for example, guide rulers or run-in rulers. The edges of the running metal strip, on which the devices for lateral guidance act, causing a great wear on the - on the guide rulers or inlet rulers attached - wear strips or their wear surfaces. The band edges, which are guided with high lateral forces, cut into these wear strips, especially with thinner bands under sparks flying over the entire length of the band - which can be over 2000 m long. The wear surfaces of the wear strips must therefore be renewed several times a week, depending on the production program.

It is known to reduce the effort not always replace the entire Schleißleisten the guide rulers, but for example, by moving the Schleißleisten the incising band new guide surfaces suspend; that is for example in DE1427923 described. The disadvantage here is that ultimately always the costly and expensive to produce Führungslineale need to be replaced. In addition, there is a risk that, when changing the distance, the gap between the roller table rollers and the guide ruler assumes dimensions that can cause misalignment such as threading or damming of the metal strip.

In a modification of this strategy is in DE69408332T2 proposed to provide outstanding areas of the inner, the metal strip facing boundary surfaces of the guide rulers, which can be moved to expose new areas for wear. The disadvantage here is that when threading the beginning of a metal strip there is a risk that - especially with thin tapes - the edges of the tape head can spit on the protruding areas and the metal strip is damaged.
In order to avoid threading thin metal bands between the roller table rollers, the center distances of the roller table rollers are usually kept as low as possible, which is why the outstanding areas are very narrow and thus the guide lengths of the individual outstanding areas are very short. Intermediate tables, which would increase the roller table distance and the guide length, are usually avoided in order to avoid threading the tape head and not to damage finished rolled strip underside.

Another known measure for avoiding incised grooves provides to allow perpendicular to the running direction of the metal strip standing axes rotatable rollers from the inner, the metal strip facing boundary surfaces of the guide rulers. The rolling on such guide rollers reduces their wear and does not create continuous grooves. However, with the use of such rollers for lateral guidance with thinning metal bands, the danger that their edges are damaged by the guide rollers increases; Therefore, the use of such guide rulers is possible only for limited metal strip thicknesses. In addition, here edges of the tape head spit on the outstanding leadership roles.

Summary of the invention Technical task

It is the object of the present invention to provide an apparatus and a method for operating the device, which reduces the expense of replacing worn parts and is suitable for all metal strip thicknesses, without having the disadvantages mentioned.

Technical solution

This task is solved by a
Device for lateral guidance of a running on a metal belt conveyor metal strip comprising
at least one main body module with management level
such as
at least one wear body with wear surface,
characterized in that
at least one wear body
can be rotated about an axis of rotation at an angle between 60 ° and 90 °, preferably substantially perpendicular, to the guide plane.

Preferably, all wear bodies are designed in this way.

The metal belt conveyor device is, for example, a roller table, for example a roller table of a belt coiler.

The metal strip is for example a steel strip or an aluminum strip.

The main body module with guide level is, for example, a so-called guide ruler or run-in ruler, which has a suitable surface for guiding the metal strip, the guide plane .. It can for example be formed by one - or more - on a support body attached wear plate (s); Support body and wear plate (s) together then form the main body module. The lateral guidance device may comprise a base body module or a plurality of base body modules. For example, two main body modules, for guiding on one side of the metal strip one each.

The guide level is used for lateral guidance of the metal strip by means of contact with the sides of the metal strip. It limits the freedom of movement of the metal strip in their direction, whereby the metal strip is guided laterally.

In addition to the main body module, the device for lateral guidance also additionally comprises at least one wear body with a wear surface. The wear body is a different component than the main body module, but can be inserted into the main body module or attached to it.
The wear body has at least one wear surface, which faces the metal band when the metal band is guided and wears out as a result of contact with the metal band in the course of the lateral guidance of the metal band.
The metal strip cuts into the wear body - for example, a steel hot strip, which must be performed at a temperature of about 600 ° C and a speed of about 60 km / h - which is basically a desired effect, because the incised contours strengthen the guiding effect for the metal band. According to a variant, the material of the wear body can be selected with regard to its hardness so that on the one hand the cutting of the guide improving contours promoted, and on the other hand, the replacement intervals are kept to an acceptable extent. The wear body can also have from the outset guide contours for guiding the metal strip, which are still deepened by the cutting of the metal strip during operation.

Advantageous Effects of the Invention

According to the invention, at least one wear body is rotatable about an axis of rotation which is at an angle between 60 ° and 90 °, preferably substantially perpendicular, to the guide plane. The limits of this area are included.
If the wear of a portion of the wear surface of the wear body exceeds an acceptable level, the wear body may be rotated about the axis of rotation, thereby turning a still unconsumed portion of the edge of the metal band and wiping it. By repeatedly twisting the need for replacement of the wear surface or the wear body can be delayed, as always new, not worn areas of the edge of the metal strip are facing.

Under substantially perpendicular is to be understood that the axis of rotation are vertical or up to 5 °, preferably up to 2 ° may deviate from the vertical.

Preferably, the wear body is rotationally symmetrical with respect to its axis of rotation, particularly preferably rotationally symmetrical.
This has the advantage in rotationally symmetrical firing bodies that when rotated by 360 / n degrees - where n is the index of rotational symmetry - the extent of lateral guidance through the wear body - in the sense of contact between metal band and wear surface - unaffected by whether and how often the wear body has been rotated by 360 / n degrees from a starting position - the length over which it is guided - the guide length - always remains the same.
In rotationally symmetrical Schieißkörpern this applies accordingly, even regardless of the angle of rotation.

Most preferably, the wear body is a round disc, whose base surface forms the wear surface of the wear body, and which is rotatable about an axis of rotation perpendicular to its wear surface, wherein the axis of rotation is in the center of the circular disc. The wear body is rotationally symmetrical with respect to the axis of rotation in this case. In this way, regardless of the rotational position in which the wear body is located - that is, regardless of how many degrees it was rotated starting from a starting position - the metal band is always guided over the same length by the wear surface. The extent of lateral guidance by the wear body in the sense of contact between the metal band and the wear surface thus remains essentially unaffected by how much the wear body has been twisted starting from a starting position. Of course, the length over which the metal strip is guided by the wear surface, may vary slightly due to other factors - for example, it may vary slightly depending on whether the metal strip in existing cuts in the wear surface and thereby forced a slight change in the direction ,
The wear body may also have other shapes than a round disk, for example a polygonal disk - for example a hexagonal disk.

According to a preferred embodiment, at least one wear body can be arranged in a recess of the at least one main body module. If the at least one wear body in a recess of the at least one Basic body modules is arranged, it is possible to make a simultaneous guidance of the metal strip through the main body module and the wear body - for example, if the wear surface of the wear body does not protrude beyond the management level of the main body module, but at least partially lies in it. Or when the wear surface of the wear body does not protrude beyond the management level of the main body module and is not in it, but is further away from the metal strip as the management level of the main body module - and that if the metal strip so far cuts into the main body module, that it also with the wear surface of the wear body comes into contact and is guided thereby.

Preferably, the recess is round. This allows easy rotation of a arranged in this recess wear body when it is rotationally symmetrical or rotationally symmetrical with respect to its axis of rotation.
If the recess is not completely enclosed by the base body module, in this embodiment the edge of the recess in the base body module follows a part of a circle.
The recess may also have other shapes.

Preferred dimensions of the wear body - and possibly the recess - arranged so that the immersed under the upper edge of the roller conveyor is as large as possible. The metal strip runs substantially along the roller conveyor upper edge; the larger the part of the wear body - especially a rotationally symmetrical wear body, and more particularly a round disc as a wear body - which dips under the upper roller track, the greater the length offered by the wear body to the metal band for guidance, resulting in better guidance.
In the case of a round Schleißkörpers and a roller table with roller blocks as a metal belt conveyor device, it is therefore preferred that the axis of rotation is arranged above the center between the axes of rotation of the roller table rollers. Then, the realization of a maximum guide length is possible for the relevant Schleißkörper in the relevant roller table, because in such a case, the Schleißkörper can dive deeper into the space between the roller blocks as if its axis of rotation would be laterally offset with respect to the center between the roller blocks.

Particularly preferred is an embodiment in which in a round recess of the wear body as a round disc whose base surface, the wear surface of the Abrasive body forms, and which is rotatable about an axis of rotation perpendicular to its wear surface, wherein the axis of rotation is in the center of the circular disc is executed, wherein preferably the Schleißkörper fit - of course with a small gap to allow rotational movement - is arranged in the recess , Then there is little danger that edges of the tape head spit on gaps between wear body and management level, and the rotation of the wear body can be accomplished without the need for additional movements of the wear body. In a trained as a polygonal disk Schleißkörper in a precisely fitting recess, for example, a rotation of the wear body would only be possible after the wear body is moved out of the management level, after twisting he would have to be moved back into the management level. This takes time and requires suitable drive units. An advantage of a polygonal disk in a precisely fitting recess, that practically there is a safeguard against unintentional rotation of the wear body.
If the recess is to allow twisting without such moving out / in, a sufficiently large gap must be present between the edge of the recess and the polygon disc. This has the disadvantage that corners of a tape head can spit on such columns.

Preferably, the device according to the invention comprises at least one wear body which is adjustable with respect to the distance of its wear surface from the guide plane of the main body module. Thus, the wear body can be adjusted relative to the main body module with respect to distance to a leading metal band in different positions.

In a so-called guiding position, at least part of the wear body lies outside the guide plane of the base body module, namely in the direction of the leading edge of the metal strap. It is thus closer to the leading metal band than the main body module; then the lateral guidance of the metal strip is performed primarily by this part of the wear body or its wear surface, and not by the management level of the main body module. In this way, the expensive and expensive to be manufactured base module is much less worn, it is apart from the inlet of the tape head almost no wear.

The wear body can be adjusted, for example, by being pushed out of the guide plane by a movement perpendicular to the guide plane - by means of appropriate adjustment devices. When displaced vertically, in the guiding position, the entire wear surface is out of the guide plane, and all points of the wear surface are equidistant from the guide plane, which promotes uniform wear by the metal strip.
A displacement which is perpendicular to the guide plane is particularly preferred, for example, when the wear body is a round disc whose base surface forms the wear surface of the wear body and which is rotatable about its axis of rotation perpendicular to its wear surface, the axis of rotation being the center of rotation round disc lies. In this case, the displacement takes place in the direction of the axis of rotation, which is also perpendicular to the management level. Such an embodiment is particularly easy to build.

The wear body can also be adjusted by being tilted about an axis, which axis may be in the guiding plane or outside the guiding plane. In such a case, part of the wear body and its wear surface outside the guide plane of the main body module may lie in the direction of the leading edge of the metal strip, and other parts in the guide plane or outside the guide plane on the side of the guide plane facing away from the metal strip to be guided. In the guide position of the wear body can be rotated in this case about an axis of rotation, for example, although it is perpendicular to its wear surface, but not perpendicular to the management level.

Preferably, the wear bodies are interchangeable, so that when excessive wear of these components can be easily replaced. A more complex replacement of the main body modules -beziehungsweise parts of the main body modules such as wear plates - is less often necessary. This saves effort and costs in the maintenance of the device for lateral guidance.
The Schleißkörper, for example, in the leadership position - in which they take over the sole tape guide - are set as soon as the tape head of the metal strip has passed the device for lateral guidance, because then there is no longer the danger that its corners spit. The wear of the expensive main body module is then significantly reduced, instead wears according to the invention, the low producible wear body.

At the inlet of the tape head, there would be a danger in the case of firing bodies in the guiding position that the corners of the tape head would stick to these firing bodies. For such a phase, the wear bodies can be adjusted so - for example, by retracting into recesses of the main body module - that they do not protrude from the management level and therefore there is no danger that a tape head can spit its corners on elevations from the management level.
In such a so-called basic body position, the wear body can optionally take over the lateral guidance of the metal strip together with the guide plane of the main body module. The metal strip will wear out in this case, both the management level of the main body module and the wear surface of the wear body.

According to a preferred embodiment, at least one wear body is independent of other Schieißkörpern with respect to the distance of its wear surface of the management level of the main body module adjustable. This makes it possible to vary the number of lateral guide giving wear body, for example, depending on the requirements of the guided metal strip. Thus, the wear not necessarily required wear body can be reduced and thus the necessary maintenance costs are minimized by a multiple.
Preferably, all wear bodies are designed in this way.

According to another variant, all wear bodies are mutually adjustable with respect to the distance of their wear surface from the management level of the main body module. This makes the operation easier and requires less structural effort compared to a adjustability independently.

Preferably, the at least one wear body with wear surface,
which is adjustable with respect to the distance of its wear surface from the guide plane of the main body module, during the tape running adjustable.

• eine Parkposition
  und
• eine Führungsposition
  einstellbar ist.

According to a preferred embodiment, the device for the lateral guidance of a metal belt running on a metal belt conveyor at least one guide roller, which at least in

• a parking position
  and
• a leadership position
  is adjustable.

In the so-called guide position, the guide roller is suitable for laterally guiding the metal strip running over the metal belt conveyor. In the so-called parking position, it is not suitable for this - then the metal strip is guided through wear bodies.

In one embodiment, the guide roller is mounted on a wear body; Preferably, it is adjustable by turning the wear body in parking position or leadership position.

According to a preferred embodiment, in the guiding position, the roller surface of the guide roller is guided through an opening of the wear surface of a wear body and projects at least partially out of this wear surface.

According to one variant, the roller surface of the guide roller lies in the parking position, as seen from the edge of a metal strip to be guided in the direction of the wear surface, beyond the wear surface. If the roller surface of the guide roller seen in the direction of the wear surface beyond the wear surface - in other words below the Schleißfläche -, it does not contribute to the lateral guidance.
In the guiding position, the roller surface of the guide roller protrudes at least partially out of the wear surface - seen from the wear surface in the direction of the guide plane of the main body module, or in other words to the edge of a metal strip to be guided out. The metal strip is then primarily in contact with the guide rollers and is primarily guided by them instead of the Schleißfläche.
In this case, the axis of rotation of the guide rollers is preferably such that the guide rollers are rotated by contact with the metal strip in rotary motion. This ensures a low wear of the guide rollers, since at least a part of the metal strip at Contact on the guide roller transmitted energy is converted into a rotational movement of the rollers, rather than contribute to signs of wear. Preferably, the axis of rotation of the guide roller is substantially perpendicular to the direction of the metal strip. The guide roller can be adjusted for example by moving or unfolding or folding or twisting from the parking position in the leading position or back.

According to another variant, the roller surface of the guide roller protrudes at least partially out of the wear surface, both in the parking position and in the guide position, from the wear surface in the direction of the metal band.
By rotating the wear body, the position of the opening of the wear surface and the guide roller protruding from this opening are changed. Accordingly, by rotating the wear body to a position where a metal strip to be guided comes into contact with the guide roller and can be guided thereby, the guiding position can be adjusted. Between leadership by shooting bodies and leadership by means of guide rollers can therefore be easily selected.
In the guide position, the axis of rotation of the guide rollers is preferably such that the guide rollers are rotated by contact with the metal strip in rotary motion. This provides for a low wear of the guide rollers, since at least a part of the energy transferred from the metal strip upon contact with the guide roller energy is converted into a rotational movement of the rollers, instead of contributing to wear. Preferably, the axis of rotation of the guide roller is substantially perpendicular to the direction of the metal strip.
In the park position of the wear body or the opening in the wear surface is positioned so that the outstanding from the wear surface leadership does not come into contact with the metal strip to be - the leadership of the metal strip is carried by the wear body.

Accordingly, in the device according to the invention by adjusting the guide roller in leadership position if necessary, the advantage of lateral guidance can be used by guide rollers, and if that is no longer desirable or necessary - for example, in thin metal bands with thicknesses up to 5 mm - by adjusting the leadership in the parking position, the lateral guidance are made again by the Schleißflächen.

The provision of such guide rollers thus has the advantage that, depending on the thickness of the metal strip to be guided between guide by means of guide rollers and leadership can be selected by means of Schieißkörpern. Or it may, depending on whether there is a risk of spitting corners of the tape head or damage edges of the metal strip, be selected between leadership by means of guide rollers and leadership by means of firing.
For example, with thick metal bands - for example, with thicknesses above 5mm - the risk that the band edges of the tape head are damaged by protruding rollers are very low or not at all. For thick metal bands, therefore, you will bring the leadership role before entering the metal strip in leadership position. Likewise, a combination of guiding the metal strip with guide rollers and the guide rollers upstream or downstream Schieißkörpern possible.

According to one embodiment, at least one wear body can be pivoted about a pivot axis.
Preferably, it can be swiveled at least partially out of the guide plane. Preferably, the pivot axis is substantially horizontal. Under substantially horizontal is to be understood that the rotation axis are vertical or up to 5 °, preferably up to 2 ° may deviate from the vertical.
A leading metal band tends to bulge in sections. As a result, during operation of a metal belt conveyor such as a roller table, it may happen that the edges of the metal strip along the side guides from a roller table wander vertically upward. If a Schleißkörper is pivoted about a pivot axis so that it projects at least partially after pivoting above the metal strip out of the leadership level, then he can prevent further contact with the metal strip further migration of the band edge upwards.
If it should be desired to force a metal band to move upwards, the wear body can be pivoted so that it protrudes after pivoting below the metal strip at least partially from the management level.

If a wear body is adjustable with respect to the distance of its wear surface from the guide plane of the main body module, it may also be pivotable about a pivot axis when it is outside the management level. Preferably, the pivot axis is substantially perpendicular to the axis of rotation, more preferably, the pivot axis and the axis of rotation intersect.
Preferably, the pivot axis is substantially horizontal.

Another object of the present application is a
Method for laterally guiding a metal strip running over a metal belt conveyor by means of a device for laterally guiding the metal strip comprising at least one main body module with a guide plane and at least one wear body with a wear surface,
and, if applicable, at least one leadership role,
characterized in that
after a first side guide phase on at least one side of the metal strip by means of the base body module, and optionally at least one wear body,
in a subsequent second side guide phase, the lateral guidance on at least one side of the metal strip
in one of the following ways:

• only by means of wear bodies,
• only by means of guide rollers,
• by means of firecrackers and guide rollers.

In the case of lateral guidance in the second lateral guiding phase, only one sliding body or several wear bodies can lead laterally by means of shooting bodies.
In the case of lateral guidance in the second lateral guiding phase, only one guide roller or several guide rollers can guide laterally by means of guide rollers.
In the case of lateral guidance in the second lateral guidance phase, a wear body or a plurality of wear bodies and a guide roller or a plurality of guide rollers can lead laterally by means of firing bodies and guide rollers.

A first phase of the lateral guidance is called here the first lateral guidance phase. A second phase of the lateral guidance is called here second lateral guidance phase.

As described above, there are phases of the lateral guide for a metal strip to be guided, in which it is advantageous to a metal strip by means of the management level lead without protruding from these surveys - for example, at the inlet of the tape head. This causes wear at the management level. In such a phase may optionally also a wear body in basic body position - ie in a position in which it does not form a survey from the management level - together with the management level of the main body module take over the lateral guidance of the metal strip. The metal strip will wear out in this case, both the management level of the main body module and the wear surface of the wear body.

If the need for such a lateral guide for the metal strip in question is over - for example, when the tape head has left the range of the device according to the invention - wear of the management level is avoided according to the invention by the leadership for the majority of the metal strip only by means of wear body.
This can be achieved, for example, with the device according to the invention with at least one wear body, which is adjustable with respect to the distance of its wear surface from the guide plane of the main body module. Thus, the distance of the wear body can be adjusted to the leading to metal band in position in which he is closer to the metal strip than the main body module - the leading position.
The Schleißkörper, for example, in the leadership position - in which they take over the sole tape guide - are set as soon as the tape head of the metal strip has passed the device for lateral guidance, because then there is no longer the danger that its corners spit. The wear of the main body module is then significantly reduced for the majority of the tape length.

Preferably, after the first side guide phase, at least one wear body and / or the at least one base body module are adjusted to a position in which the wear surface of the wear body lies outside the guide plane.
For example, a wear body whose wear surface lies within the guide plane during the first side guide phase can be moved further in the direction of the metal strip to be guided. Or, the guide module may be further moved away from the metal strip to be led so that the wear body, which remains in its original position, is closer to the metal strip than the guide module.

According to a preferred embodiment, the lateral guidance of the metal strip takes place in the first lateral guiding phase and / or the second lateral guiding phase in at least one wear body by means of at least one guiding roller. As described above, it is sometimes advantageous to have a leadership function of leadership roles.

According to a preferred embodiment, the method according to the invention proceeds such that during the second lateral guiding phase the lateral guidance takes place on at least one side of the metal band by means of several wear bodies, during which at least one wear body displaces away from the metal band while losing the contact of its wear surface with the metal band during the second lateral guiding phase becomes,
then this wear body is rotated about a rotation axis perpendicular to its wear surface,
and then this Schleißkörper is again adjusted under construction of contact of its wear surface with the metal strip to the metal strip.
This makes it possible, during the tape run to be able to respond to wear-related need for reinforcement of the prevailing leadership function. Worn wear bodies can be twisted during the tape run in positions in which still unworn areas of their wear surface are exposed to the metal strip.

According to a preferred embodiment, at least one wear body is pivoted about a pivot axis.
Preferably, it is at least partially pivoted out of the guide plane out, where it then protrudes above or below the metal strip from the management level.

Device and method according to the invention make it possible to significantly reduce the maintenance effort compared to conventional devices. It is the time required for the replacement of worn parts reduced, since the wearer must be replaced less frequently than conventional Schleißleisten by repeatedly exposing still unspoiled areas of the wear surface of a wear body to the metal band. The replacement can take place in the course of other maintenance shutdowns, production loss due to a short maintenance interval for wear surfaces can be avoided. It will also reduce the cost of exchanging Abrasive bodies kept low, the Schleißkörper can be made easily and cheaply.

The roller surfaces of the guide rollers 22a, 22b, 22c, 22d in the FIGS. 7 to 10 protrude both in the parking position as well as in the leading position of the wear surface in the direction of metal strip seen partially from the wear surface. They are through an opening of the wear surface of the respective wear body 21 a, 21 b, 21 c, 21 d out and protrude from this wear surface.
By rotating the Schleißkörper 21 a, 21 b, 21 c, 21 d, the position of the openings of the wear surfaces between FIG. 7 and FIG. 9 changed. The outstanding from these openings guide rollers 21 a, 21 b, 21 c, 21 d are repositioned accordingly and protrude even after the rotation of the wear body 21 a, 21 b, 21 c, 21 d out of these openings. Accordingly, they are placed in the leadership position.
In this case, the axis of rotation of the guide rollers is substantially perpendicular to the direction of the metal strip.

The guide rollers 22a, 22b, 22c, 22d, for example, each at Drehverstellmodulen - as in FIG. 4 provided with the reference numeral 13 - attached and be rotatable and adjustable by them.
They could also be attached to the firecrackers.

FIG. 11 shows one too FIG. 6 largely analogue figure. In addition to FIG. 6 is also a part of the management level indicated by the reference numeral 25. When closed, the wear body 15c is shown enclosed in a position in which its wear surface 17c lies in a plane with the guide plane 25. Edged dashed lines it is shown in a position in which the distance of its wear surface from the management level adjusted, here enlarged, was by being pushed out of the management level by a movement perpendicular to the management level - by means of an adjusting device not shown in detail.

FIG. 12 shows one too FIG. 6 largely analogue figure. In addition to FIG. 6 is - as in FIG. 11 - Part of the management level represented by the reference numeral 26. When closed, the wear body 15c is shown enclosed in a position in which its wear surface 17c lies in a plane with the guide plane 26. Edged with a dashed line, it is displayed in a position in which it is not - for the sake of clarity shown separately - pivot axis was partially pivoted out of the guide plane 26 out, where it then protrudes above the metal strip 18 from the guide plane 26.

While the invention has been further illustrated and described in detail by the preferred embodiments, the invention is not limited by the disclosed examples, and other variations can be derived therefrom by those skilled in the art without departing from the scope of the invention.
