    DEVICE AND METHOD FOR GUIDING METAL TAPES WITH WEARING BODIES
    FIELD OF TECHNOLOGY
    The present invention relates to a device for lateral guidance of a metal belt running on a metal belt conveyor belt comprising at least one main body module with a substantially vertical management level.
    STATE OF THE ART
    In the production of metal strips these are by means of metal belt conveyors, such as roller tables, to processing machines - for example, reels - directed - where they are wound. 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 surface. 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 replace the effort not always replace the entire Schleißleisten the guide rails, but for example, by moving the Schleißleisten the incising tape suspend new guide surfaces; This is described for example in DE1427923. The disadvantage here is that ultimately always the expensive and expensive to produce guide rails must 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 proposed in DE 69408332T2 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.
    In US2818954 it is proposed to provide for guiding a plurality of arranged at an angle to the conveying direction guide discs. By twisting these guide discs new areas can be exposed to wear.
    A known measure for avoiding incised grooves provides to perpendicular to the direction of the metal strip standing axes rotatable rollers from the inner, the metal strip facing boundary surfaces of the guide rulers protrude. 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.
    JP05161917 proposes to use "umbrella-like-rolls" to guide in a "side-guide" to avoid damage to the metal strip, which are held by a liquid flow in a constant rotational movement.
    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 cost of replacing worn parts and is suitable for all metal strip thicknesses, without having the disadvantages mentioned.
    TECHNICAL SOLUTION
    This object is achieved by a
    Device for the lateral guidance of a metal belt running on a metal belt conveyor belt comprising at least one main body module with a substantially vertical management level, characterized in that at least one controlled in several defined rotational positions rotatable wear body with wear surface is present, and the wear surface substantially flat and in all defined rotational positions parallel to the management level.
    The metal belt conveyor, for example, a roller table, for example, a roller table of a tape coiler. The conveying plane of the metal belt conveying device is generally aligned substantially horizontally.
    The metal strip is for example a steel strip or an aluminum strip.
    The main body module with management level, for example, a so-called guide ruler or inlet ruler, which has a suitable for guiding the metal strip surface, the management level. It may be formed, for example, by one or more wear plates mounted on a support body; Support body and wear plate (s) together then form the main body module.
    The lateral guidance device may comprise a main body module or a plurality of main body modules. For example, two main body modules, for guiding on one side of the metal strip one each.
    The management 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.
    The guide plane is oriented substantially vertically.
    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 body that is subject to wear as a result of the guidance of the metal strip, at an area which is referred to as 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; this is turned towards the metal strip when the metal strip is guided and wears due to contact with the metal strip in the course of the lateral guidance of the metal strip.
    The metal strip cuts into the wear body - for example, in 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 enhance the guiding effect for the metal band. According to a variant, the material of the wear body, or at least its wear surface, can be selected with respect to its hardness so as to promote, on the one hand, the cutting of contours improving the guide and, on the other hand, to keep the replacement intervals to an acceptable level.
    According to one embodiment, at least one wear body has at least one carrier material with a coating.
    It may, for example, a substrate be surface-coated - for example, ceramic, powder-coated, welded; For example, with a material that is more resistant to wear than the substrate. It can also be applied to a carrier material, a plate made of a, possibly different from the carrier material, for example, by screwing.
    A coating, for example surface coating, of the carrier material may also consist of several layers of different materials. For example, an outer layer may be relatively soft to facilitate cutting the metal strip to form guide grooves, and a layer lying between this outer layer and the substrate may be relatively hard, which makes deeper cutting difficult.
    Coating, for example, surface coating, depending on the desired use, be the same everywhere on the wear body or be segmentally different.
    According to one embodiment, the Schleißkörper are so symmetrical that they can be easily reversed after wear of one side and thus another equally pronounced side facing the metal strip and worn.
    The wear surface is essentially flat in the unworn state. It is also included that the wear body in the wear surface from the outset - so before startup, in unworn new condition - may have guide contours for guiding the metal strip, which are still deepened by the cutting of the metal strip during operation. Preferably, however, it is executed in the unworn state plan without such guide contours.
    The wear surface is the region of the wear body which is provided in operation for the guidance of the metal strip. Of course, the so-called wear body can also have areas that will not come into contact with the metal strip during operation, for example due to their removal from the pass-line of the roller table or the plane defined by the upper edge of the roller table rollers.
    The wear body may be round or have other contours. It may also be ausgebil-det as a wheel with spokes, which accordingly contain the rim of the wheel or the Schleißfläche, and the spokes fix the rim on a rotation axis.
    The wear body may also be chamfered laterally to avoid the risk of spitting of the metal strip on the edge of the wear body; if the wear body is a disk so for example between side surface and base of the disc.
    The wear body can, preferably outside the wear surface, have guide elevations. In practice it has been found that metal straps may tend to run up the wear bodies, ie increase their distance from the lowermost end of the wear body. In order to avoid such an undesirable run-up, guide surveys may be provided on the wear body, which prevent run-up and leave the wear surface provided on Schleißkörper and optionally direct the metal strip down again.
    Such guide elevations may be, for example, a plurality of discrete elevations from a surface of the wear body lying in a plane with the wear surface; So separate individual surveys from a plane. Or the Schleißkörper is designed such that at one edge of the wear surface next to the Schleißfläche a survey against the plane of the wear surface is present, this survey is either present on this entire edge, or has interruptions, so only partially present on the edge. The survey is preferably carried out such that it does not rise abruptly from the plane of the wear surface to a fixed height, but their height increases with increasing distance from the edge of the wear surface, called run-on slope.
    A guide survey, especially such a run-in slope, narrows the lateral space for the metal strip during operation. The constriction sets resistance to the run-up of the metal strip.
    The wear body is controlled in a plurality of defined rotational positions rotatable. He can therefore take at least two defined rotational positions, between which the operator can select specifically and control the rotation controlled accordingly and / or can regulate.
    Preferably, several wear bodies are present. As a result, guidance can increasingly take place through the wear bodies.
    Preferably, all Schleißkörper are carried out according to the invention. As a result, a maximum benefit is drawn from the advantages associated with the device according to the invention.
    ADVANTAGEOUS EFFECTS OF THE INVENTION
    Compared to US2818954 with their arranged at an angle to the conveying direction guide discs can be realized with the device according to the invention by the substantially planar and parallel to the guide plane wear surface a greater guide length for the metal strip. As a result, a lower surface pressure is caused in comparison, which on the one hand means less risk of damaging an edge of the metal strip and therefore thinner tapes can be treated. On the other hand, this results in less wear on the wear bodies, which leads to increased life or lower replacement requirements; in practice, for example, results in a six-fold increased replacement interval.
    Compared with JP05161917 with rotating rollers, the inventive ingestion of defined rotational positions leads to an improved guidance function by cutting the metal strip into the wear body and improved distribution of wear on different regions. As a result, for example, comparatively thinner metal strips can be treated.
    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 - or of 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.
    According to one embodiment, a plurality of rotatable in several defined rotational positions Schleißkörper with wear surface are present, and at least one of these Schleißkörper is independent of other wear bodies rotatable. As a result, when exposing new areas, consideration can be given to the extent of wear on individual wear bodies and individually rotated as needed. This can further reduce the renewal effort for worn wear bodies.
    According to one embodiment, a plurality of rotatable Schleißkörper in a plurality of defined rotational positions with Schleißfläche available, and at least one of these Schleißkörper is rotatable depending on at least one other of these Schleißkörper. Thus, when exposing new areas, consideration can be given to the extent of wear of groups of at least two abrasive bodies, and such groups can be rotated as needed. This can further reduce the renewal effort for worn wear bodies.
    A wear body is rotatable about an axis of rotation. If the wear of a portion of the wear surface of the wear body exceeds an acceptable level, the wear body may be controllably rotated about the axis of rotation, thereby facing and wiping a still unused portion of the edge of the metal belt. By repeated controlled rotation, the need to replace 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.
    Preferably, the wear body is substantially rotationally symmetrical with respect to its circumference seen in the direction of rotation axis, particularly preferably rotationally symmetrical. It is hereby included that the wear body has recesses at its edge, which interrupt such a circumference in parts.
    This has the advantage in rotationally symmetrical wear bodies that when rotated by 360 / n degrees - where n is the count of rotational symmetry - the extent of the lateral guidance of the wear body -in the sense of contact between metal band and wear surface - essentially unaffected thereof it remains whether and how often the wear body has been rotated by 360 / n degrees starting from a starting position - the length over which it is guided - the guide length - always remains the same.
    In rotationally symmetrical wear bodies that 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 is arranged in a recess of the at least one main body module, it is possible to perform a simultaneous guidance of the metal strip by 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 you are lying. If the wear surface as claimed in the invention is substantially planar and parallel to the guide plane, this may be the case, because parallel to the guide plane also comprises in a plane with the guide plane. 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 comes into contact and is guided by it.
    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 main body module, in this embodiment, the edge of the recess in the main body module follows a part of a circle.
    The recess may also have other shapes.
    Preferred dimensions of the wear body - and optionally the recess - arranged so that the submerged below the upper edge roll-up is as large as possible.
    The metal strip runs essentially along the upper edge of the roller conveyor; the larger the part of the wear body - especially a rotationally symmetrical wear body, and more particularly a round disc as wear body, which dips under the upper roller track, the greater is the length offered by the wear body the metal band for guidance, which causes better guidance.
    In the case of a round Schleißkörpers and a roller table with roller table rollers as a metal band conveyor device, it is therefore preferred that the axis of rotation for the rotatable Schleißkörper lies above the middle between the axes of rotation of the roller table rollers. Then, the realization of a maximum guide length is possible for the subject Schleißkörper in the relevant roller table, because in such a case, the Schleißkörper can dive deeper into the space between the roller table rollers as if the axis of rotation would be laterally offset with respect to the middle between the roller table rollers.
    Particularly preferred is an embodiment in which in a round recess of the wear body as a round disc whose base surface forms the wear surface of the wear body, and which is rotatable about a rotation axis perpendicular to its wear surface, wherein the axis of rotation is in the center of the circular disc , is executed, wherein preferably the wear body fits accurately - of course, with a small gap to allow a 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 it 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 virtually a safeguard against unintentional rotation of the wear body is - ie defined rotational positions are defined by the shape of the recess.
    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.
    According to one embodiment, the device according to the invention comprises at least one wear body, for which the distance of its wear surface from the guide plane of the main body module is adjustable. Thus, the wear body or the main body module can be adjusted with respect to distance to a leading metal band in different positions. For example, when the wear body contacts the metal band, the distance of its wear surface from the guide plane of the body module may be changed, for example, by moving the body module away from the metal band. In another variant, the wear body is moved in the direction of metal strip, that increases the distance of their wear surface of the management level of the main body module, for example, until the wear body has contact with the metal strip; This reduces a lateral freedom of movement for the metal strip more and more.
    In a so-called guiding position, at least part of the wear body lies outside the guide plane of the base body module, specifically 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 carried out 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 Schleißkörper, for example, in the leadership position - in which they take 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 more 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 wear bodies in the guiding position that the corners of the tape head would be stuck to these wear 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 a so-called basic body position, the wear body can possibly take over the lateral guidance of the metal band 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.
    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 that is perpendicular to the guide plane is particularly preferred, for example, when the wear body is a round disk whose base surface forms the wear surface of the wear body, and which is rotatable about its axis perpendicular to its wear surface, the axis of rotation lies in the center of the round disc. 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.
    According to a specific embodiment thereof, the distance of its wear surface from the guide plane of the main body module is adjustable for at least one wear body independently of other wear bodies.
    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. As a result, it is possible to take specific account of the need for guidance by means of the guide plane or wear body in specific areas of the device and to adjust it individually in such areas per wear body. 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 embodiment thereof, a plurality of wear bodies, for which the distance of their wear surface from the management level of the main body module is adjustable, is present, wherein it is adjustable in at least one of these wear bodies depending on at least one other of these wear body.
    As a result, it is possible to take specific account of the need for guidance by means of the guide plane or wear body in special areas of the device which extend over the extent of groups of wear bodies, and be adjusted as required for such groups. This can further reduce the renewal effort for worn wear body and makes the operation easier and requires less structural effort compared to a Einbarkeitbarkeit independently.
    Preferably, all of these wear bodies are adjustable as a function of at least one other of these wear bodies, that is, all wear bodies can be adjusted in a composite manner.
    Preferably, the at least one wear body, for which the distance of its wear surface from the guide plane of the main body module is adjustable during the tape running adjustable.
    According to a preferred embodiment, the device has at least one wear body guide roller, which is guided through a recess of the wear surface of a wear body or an opening of the wear surface of a wear body and at least partially protrudes from this wear surface.
    By an opening of the wear surface is meant a hole in the wear surface which is completely surrounded by the wear surface. In contrast, a recess of the wear surface is not completely surrounded by the wear surface.
    Accordingly, in the device according to the invention, 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 -, made the lateral guide again from the wear surfaces become.
    The provision of the Schleißkörper guide rollers thus has the advantage that, depending on the thickness of the metal strip to be guided between leadership by Schleißkörper guide rollers and guide can be selected by means of wear bodies. 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 Schleißkörper-leadership roles and leadership by means of wear bodies.
    According to a preferred embodiment, the device has at least one wear body guide roller, which is adjustable at least in a parking position and a guide position.
    In the so-called guide position, the wearer body guide roller is adapted to guide the metal belt running over the metal belt conveyor laterally. In the so-called parking position, it is not suitable for this - then the metal strip is guided by wear body and / or the management level.
    In one embodiment, the wear body guide roller is attached to or on a wear body; Preferably, it is adjustable by turning the Schleißkörper in parking position or leadership position.
    The wear body guide roller may also be attached to the main body module, or to other parts of the device, or to adjacent devices.
    According to a preferred embodiment, in the guiding position, the roller surface of the wear body guide roller is guided by a recess of the wear surface of a wear body or an opening of the wear surface of a wear body and protrudes at least partially from this wear surface.
    According to one variant, the roller surface of the wear body guide roller lies in the parking position from the edge of a metal strip to be guided in the direction of the wear surface beyond the wear surface. When viewed in the direction of the wear surface, the roller surface of the wear body guide roller lies beyond the wear surface, in other words below the wear surface, it does not contribute to the lateral guidance. In the guiding position, the roller surface of the wear body guide roller protrudes at least partially out of the wear surface - seen from the wear surface in the direction of the main body module's guide plane, or in other words to the edge of a metal strip to be guided. The metal strip is then primarily in contact with the Schleißkörper guide rollers and is guided primarily by them instead of by the Schleißfläche.
    In this case, the axis of rotation of the Schleißkörper guide rollers is preferably such that the Schleißkörper guide rollers are put into contact with the metal strip by rotation. This provides for a low wear of the wearer body guide rollers since at least a portion of the energy transferred from the metal belt upon contact with the wearer body guide roller is translated into rotational motion of the rollers rather than contributing to wear. Preferably, the axis of rotation of the wear body guide roller is substantially perpendicular to the direction of the metal strip.
    The Schleißkörper-leadership role can be set, 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 wear body guide roller projects 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 or recess of the wear surface and the outstanding from this opening or recess wear body guide roller is changed. Accordingly, by rotating the wear body to a position in which a metal strip to be guided comes into contact with the wear body guide roller and can be guided thereby, the guide position can be adjusted. Between leadership by Schleißkörper and leadership by means of Schleißkörper guide rollers can therefore be easily selected.
    In the guide position, the axis of rotation of the Schleißkörper guide rollers is preferably such that the Schleißkörper guide rollers are offset by contact with the metal strip in rotary motion. This provides for a low wear of the wearer body guide rollers since at least a portion of the energy transferred from the metal belt upon contact with the wearer body guide roller is translated into rotational motion of the rollers rather than contributing to wear.
    Preferably, the axis of rotation of the wear body guide roller is substantially perpendicular to the running 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 Schleißkörper-guide roller does not come into contact with the metal strip to be - the leadership of the metal strip is carried by the Schleißkörper.
    Accordingly, in the device according to the invention by adjusting the Schleißkörper guide roller in leadership position, if necessary, the advantage of lateral guidance can be used by Schleißkörper 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 Schleißkörper-leadership role in the park position, the side guide back from the
    Schleißflächen be made.
    The provision of such Schleißkörper guide rollers thus has the advantage that, depending on the thickness of the metal strip to be guided between leadership by Schleißkörper guide rollers and leadership can be selected by means of wear bodies. 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 Schleißkörper-leadership roles and leadership by means of wear bodies.
    For example, in thick metal bands - for example, with thicknesses above 5mm - the risk that the band edges of the tape head are damaged by protruding roles very low or not given. For thick metal bands you will therefore bring the Schleißkör-by-leadership role before entering the metal strip in leadership position.
    Likewise, a combination of guiding the metal strip with Schleißkörper-Füh-rungsrollen and the Schleißkörper guide rollers upstream or downstream wear bodies is possible.
    A further subject of the present application is a method for lateral guidance of metal belts running over a metal belt conveyor by means of a device for laterally guiding a metal strip comprising at least one main body module with guide plane and at least one wear body with substantially flat wear surface, characterized in that after a first metal band has passed through the metal belt conveyor, and before a second metal band enters the metal belt conveyor, the wear body is controlled to rotate from a first defined rotational position to a second defined rotational position, wherein the wear surface is parallel to the guide plane in all defined rotational positions is. There are two or more defined rotational positions. The terms first rotational position and second defined rotational position merely mean that there are two different rotational positions. They do not mean in this context that there are necessarily only two rotational positions.
    The terms first metal band and second metal band only mean that they are two different metal bands. In this context, they do not mean that there are necessarily only two metal bands. They do not mean in this context that between two successive metal bands forcibly always turned; rotation can also take place only after several metal bands have passed through the device before another metal band passes through the device; This metal band can also be followed by several metal bands again before turning takes place again.
    For example, at first ten metal bands may pass through the device, then rotate before an eleventh metal band passes through the device as the first metal band of a group of ten further metal bands. While metal band eleven through metal band twenty pass through the device, no rotation occurs.
    In this way, defined fresh areas of the wear body can be exposed to wear, wherein preferably the guide length is not changed by changing the orientation of the wear surfaces.
    According to one embodiment, the method is characterized in that after a first side guide phase on at least one side of the metal strip by means of basic body module, and optionally wear bodies and / or Schleißkörper guide rollers, in a subsequent second side guiding phase, the lateral guidance on at least one side of the metal strip only by means of wear bodies. Optionally, the device for laterally guiding a metal strip also comprises at least one wear body guide roller.
    In the case of lateral guidance in the second lateral guidance phase, only one wear body or several wear bodies can lead laterally by means of wear bodies.
    A first phase of the lateral guidance is referred to here as 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 leading metal strip, in which it is advantageous to guide a metal strip by means of the management level, without protruding from this 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 most 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, for which the distance of its wear surface from the management level of the main body module is adjustable.
    Thus, the distance of the wear surface of the management level, and thus the distance to the leading metal band can be adjusted to a position in which it is closer to the metal strip as the management level of the main body module - the leadership position.
    The Schleißkörper or wear surfaces can, for example, in the leadership position - in which they take 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.
    According to another embodiment, the method is characterized in that after a first side guide phase on at least one side of the metal strip by means of basic body module, and optionally wear bodies and / or Schleißkörper guide rollers, in a subsequent second side guiding phase, the lateral guidance on at least one side of the Metal strip is made in one of the following ways: - only by means of Schleißkörper guide rollers, - by means of wear bodies and Schleißkörper guide rollers.
    In this case, the device for laterally guiding a metal strip also comprises at least one wear body guide roller.
    In the case of lateral guidance in the second lateral guiding phase, a wear body guide roller or a plurality of wear body guide rollers can only lead laterally by means of wear body 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 wear body guide roller or a plurality of wear body guide rollers can lead laterally by means of wear bodies and wear body guide rollers.
    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 lateral guiding phase can be moved further in the direction of the metal band 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.
    In this case, the lateral guidance of the metal strip takes place in the second lateral guiding phase by means of at least one wear body guiding roller. As described above, it is sometimes advantageous to have a guiding function of wear body guide rollers.
    According to a preferred embodiment, the inventive method is such that during the second side guide phase, the lateral guidance on at least one side of the metal strip by means of several Schleißkörper, wherein during the second side guiding phase at least one wear body with loss of contact of its wear surface with the metal strip of Metal band is adjusted away, then this Schleißkörper controlled about a rotation axis is rotated in a new defined rotational position, and then this Schleißkörper is again adjusted by building contact of their wear surface with the metal strip towards 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 running in positions in which still un-worn areas of their wear surface are exposed to the metal strip.
    According to a preferred embodiment, the type of lateral guidance between sliding guide is changed by means of Schleißkörpern and rolling guide by means of rollers. The rollers may be wearer guide rollers or other guide rollers.
    According to a variant, the type of lateral guidance between sliding guide and rolling guide is changed during the lateral guidance of a metal strip.
    One step in this may be turning the wear bodies to a new defined rotational position, or shifting, unfolding or folding, or twisting wearer guide rollers or other guide rollers.
    According to a preferred embodiment, the type of lateral guidance comprises both sliding guidance by means of wear bodies as well as rolling guidance by means of rollers.
    The rollers may be wearer guide rollers or other rollers for guidance.
    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 is also kept low the cost of replacing wear bodies, since the Schleißkörper can be made easily and cheaply.

    In this case, the wear strip is worn and must be replaced.
    FIG. 3 shows a detail of a device according to the invention for the lateral guidance of a metal belt running over a roller table as a metal belt conveyor. Shown is the device, a main body module 7 consisting of support body 8, carrying a wear plate 9 with a substantially vertical guide plane 10. Shown are also roller table rollers 11a, 11b, 11c, 11 d. It is also shown a Schleißkörper 12, the wear surface 12a in the representation lies in a plane with the guide plane 10. The wear body 12 is controlled in a plurality of defined rotational positions rotatable. The wear surface 12a is substantially planar and in all defined rotational positions parallel to the guide plane 10. The wear body 12 is a round disc whose base surface forms the wear surface of the wear body.
    The wear body 12 is arranged in a largely round recess of the wear plate 9 - since the wear plate 9 does not completely surround the wear body 12, the recess is not quite round; however, the part comprising the wear body 12 is part of a circle.
    Also visible are chamfers between base and side surface of the round discs of Schleißkörper 12, which serve in comparison to Schleißkörper without chamfering to avoid the risk of spitting of the metal strip at the edge between the side surface and base.
    In an example analogous to Figure 3, which is not shown separately, the wear body is rotatable about a rotation axis perpendicular to the guide plane. The axis of rotation is at the center of the round disc. The axis of rotation is arranged above the middle between the axes of rotation of the roller table rollers.
    FIG. 4 shows a device as shown in FIG. 3. The main body module 7 consisting of support body 8 and the cut wear plate 9 with guide plane 10 can be seen. The wear body 12 is fastened on an adjusting device, in this case a rotary adjustment module 13, which is fastened in the main body module 7. By means of the Drehverstellmoduls 13 of the wear body 12 can be controlled rotated in several defined rotational positions. In addition, by means of the Drehverstellmoduls 13 of the distance of the wear surface 12a of the guide plane 10 of the base body module 7 can be adjusted by the Schleißkörper 12 from the management level 10 moved out and can be moved back again, which is not shown separately.
    FIG. 5 shows wear bodies 15a, 15b, 15c, 15d arranged in largely round recesses 14 of a basic body module. Roller table rollers 16a, 16b, 16c are also shown. The wear bodies 15a, 15b, 15c, 15d are round disks whose base surfaces form the wear surfaces 17a, 17b, 17c, 17d of the wear bodies 15a, 15b, 15c, 15d. The wear bodies 15a, 15b, 15c, 15d are rotatable in a controlled manner in a plurality of defined rotational positions, the substantially flat wear surfaces being parallel to the guide plane 19 in all defined rotational positions. The metal strip 18 - here a steel strip - is guided by the guide plane 19 and the wear body 15a, 15b, 15c, 15d, the wear surfaces 17a, 17b, 17c, 17d in the guide plane 19, out. Shown for the wear body 15b also several wear marks 20a, 20b, 20c, which has a metal band already in the Schleißkörper 15b - after multiple controlled turning in different defined rotational positions - has been frozen.
    FIG. 6 shows a view along the section B-B from FIG. 5 in the direction of the wear body 15c, wherein the guide plane 19 is not shown separately.
    FIG. 7 shows a device largely analogous to FIG. 5 with wear bodies 21a, 21b, 21c, 21d. There are wear body guide rollers 22a, 22b, 22c, 22d, which is adjustable at least in a parking position and a guide position. They are shown in Figure 7 in park position. The metal strip 23 - here a steel strip - is guided by the guide plane 24 and wear body 21 a, 21 b, 21 c, 21 d, the wear surfaces lie in the guide plane 24.
    FIG. 8 shows a view along the section A-A from FIG. 7 in the direction of the wear body 21c, wherein the guide plane 24 is not shown separately.
    FIG. 9 shows a view largely analogous to FIG. 7, in which reference numbers for parts described in FIG. 7 have been omitted for the sake of clarity. Shown are the Schleißkörper guide rollers 22a, 22b, 22c, 22d of Figure 7 in leadership position. The metal strip 23 is guided by the Schleißkörper guide rollers 22a, 22b, 22c, 22d.
    FIG. 10 shows a view along the section C-C from FIG. 9 in the direction of the wear body guide roller 22c, wherein the guide plane is not shown separately.
    The roller surfaces of the Schleißkörper guide rollers 22a, 22b, 22c, 22d in Figures 7 to 10 protrude both in the park position and in the leadership position of the wear surface in the direction of metal strip partially out of the wear surface. They are guided through an opening of the wear surface of the respective wear body 21a, 21b, 21c, 21d and protrude from this wear surface.
    By rotating the wear bodies 21a, 21b, 21c, 21d, the position of the openings of the wear surfaces between Figure 7 and Figure 9 is changed. The outstanding from these openings Schleißkörper guide rollers 21a, 21b, 21c, 21 d are repositioned accordingly and protrude even after the rotation of the Schleißkörper 21a, 21b, 21c, 21 d out of these openings. Accordingly, they are placed in the leadership position.
    The Schleißkörper-guide rollers 22a, 22b, 22c, 22d, for example, each of Drehverstellmodulen - as provided in Figure 4 by the reference numeral 13 - attached and rotatable and adjustable by them, so be adjustable in different positions.
    They could also be attached to or on the wear bodies, or on the base body module.
    FIG. 11 shows a largely analogous figure to FIG. In addition to FIG. 6, a part of the guide plane is also shown by 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 their wear surface from the management level adjusted, here enlarged, was by the wearer body is 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 and FIG. 13 show the difference between the recess of the wear surface of a wear body and the opening of the wear surface of a wear body.
    By an opening of the wear surface is to be understood a hole 27 in the wear surface 28, which is completely surrounded by the wear surface 28; In contrast to this, FIG. 13, surrounded by a dashed line, shows a recess 29 of the wear surface 30, which is not completely surrounded by the wear surface 30.
    FIG. 14 shows a section of an embodiment of a wear body 30 in the unworn state. The wear body 30 is a round disc with a flat wear surface 31. At the edge 32 of the wear body is chamfered.
    FIG. 15 shows a section of an embodiment of a wear body 33 in the unworn state. The wear body 33 is a round disc with a substantially flat wear surface 34. A guide groove 35 provided from the outset as guide contours for guiding the metal band in the wear surface 34 is shown. At the edge 36 of the wear body is chamfered.
    FIG. 16 shows a wear body 33 according to FIG. 15 in a lateral view of the wear surface 34. Several guide grooves 35 can be seen.
    FIG. 17 shows a section of an embodiment of a wear body 36 in the unworn state. On a carrier material 37 there is an outer, relatively soft layer 38 for the purpose of forming guide grooves during operation. Between this outer layer 38 and the carrier material 37 is a relatively hard layer 39, which makes a deeper incision difficult.
    These two surface coatings layer 38 and layer 39 are mounted symmetrically on Schleißkörper 36 on both sides, so that wear body 36 can be easily reversed after wear of one side and thus the other equally pronounced side facing the metal strip and worn.
    Figure 18 shows a side view of a wear body 40. Its wear surface 41 extends around its circumference. Outside the wear surface 41 are a plurality of separate, individual elevations from a surface 43 of the wear body 42, which lies in a plane with the wear surface 41, as guide elevations 42 available.
    Figure 19 shows a section of a section along the line A-A through the Schleißkörper 40 of Figure 18. The profile of the guide projection 42 can be seen; It can also be seen that on the other side of the trained as a round disk wear body 40 also a guide elevation 44 is present.
    Figure 20 shows a section of a Schleißkörper 45, which is designed such that at one edge of the wear surface 46 adjacent the Schleißfläche 46 a survey 47 relative to the plane of Schleißfläche 46 is present, this survey 47 at this entire edge of Wear surface 46 is present. The survey is carried out such that their height increases with increasing distance from the edge of the wear surface, so a so-called run-on slope 48 is formed.
    These run-on slope 48 and also the guide elevations 42 and 44 from FIGS. 18 and 19 narrow the lateral space for the metal strip during operation. The constriction sets resistance to the run-up of the metal strip.
    Although 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.
