Definitions
- the present invention relates to a device for laterally guiding a metal belt running over a metal belt conveyor comprising at least one main body module with a substantially vertical guide plane.
- metal strips 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 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.
- the JP05161917 proposes to use "umbrella-like-rolls" to guide in a "side-guide", which are kept in a constant rotational movement by a liquid flow to avoid damage to the metal strip.
- a Device for lateral guidance of a running on a metal belt conveyor metal strip comprising at least one main body module having a substantially vertical guide plane, characterized in that at least one wear body with a wear surface, which is rotatable in a plurality of defined rotary positions, is present, and the wear surface is essentially flat and parallel to the guide plane in all defined rotational positions.
- the metal belt conveyor device is, for example, a roller table, for example a roller table of a belt 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 guide level is, for example, a so-called guide ruler or run-in ruler, which is suitable for guiding the metal strip Surface, the management level has. It may, for example, be formed by one or more wear plates (s) 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 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.
- the management level is essentially vertical.
- 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 due to the guidance of the metal strip, at a region called the 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, 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.
- 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.
- at least one wear body has at least one carrier material with a coating.
- a carrier material may be surface-coated - for example ceramic, powder-coated, welded on; For example, with a material that is more resistant to wear than the substrate. It can also be on a carrier material a plate of a, possibly different from the carrier material, be applied, 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 can be the same everywhere on the wear body or segmentally different, depending on the desired use. According to one embodiment, the wear bodies are so symmetrical that they can be easily turned over after one side wear and thus another equally pronounced side facing the metal band 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 area of the wear body that is provided in operation for the guidance of the metal strip.
- 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 can also be designed as a wheel with spokes, wherein according to the rim of the wheel contain the wear surface or form, 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 of the wear surface, have guide elevations.
- metal straps may tend to run up the wear bodies, ie increase their distance from the lowermost end of the wear body.
- guide surveys may be provided on the wear body, which prevent run-up and leave the wear surface provided on Schlndigen 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 which is in a plane with the wear surface; So separate individual surveys from a plane.
- the Schlrich Economics is designed such that at one edge of the wear surface next to the Schlndconstruction 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-on 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 rotatable in several defined rotational positions. 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.
- wear bodies are present. As a result, guidance can increasingly take place through the wear bodies.
- all wear bodies are designed according to the invention. As a result, a maximum benefit is drawn from the advantages associated with the device according to the invention.
- the ingestion of defined rotational positions according to the invention leads to an improved guiding function by cutting the metal strip into the wear body and improving the distribution of the wear on different regions. As a result, for example, comparatively thinner metal strips can be treated.
- 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 -gearedges 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.
- a plurality of rotatable Schllustrated Schllustrated Schllustrated Schllustrated Materials in a plurality of defined rotational positions with Schllustrated Structure available, and at least one of these Schllustrated stresses is independent of other wear bodies rotatable.
- 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.
- a plurality of rotatable Schllustrate ceremonies in a plurality of defined rotational positions with Schllustrateivity available, and at least one of these Schllustrate energies is rotatable depending on at least one other of these Schllustratio.
- 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.
- the wear body is preferably substantially rotationally symmetrical, 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 lateral guidance by the wear bodies - in the sense of contact between metal band and wear surface - is substantially 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 - remains the same. With rotationally symmetrical wear bodies this applies accordingly, even independently of the angle of rotation.
- 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 metal band and wear surface Thus, it remains essentially unaffected by how much the wear body has been twisted starting from a starting position.
- 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.
- 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.
- 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.
- 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 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.
- the axis of rotation for the rotatable Schl constitution lies above the middle between the axes of rotation of the roller table rollers.
- 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 precisely - 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.
- 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 base body module is adjustable.
- the wear body or the main body module can be adjusted with respect to distance to a leading metal band in different positions.
- 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.
- 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.
- 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 Schlauer Sciences can be adjusted so - for example, by retracting into recesses of the main body module - that they are not from the Project management level and therefore there is no danger that a tape head can spit its corners on elevations from the management level.
- the wear body can optionally 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.
- 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.
- 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 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.
- a plurality of wear bodies for which the distance of their wear surface from the management level of the base 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.
- 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 adjustability independently.
- all of these wear bodies are adjustable as a function of at least one other of these wear bodies, that is to say all wear bodies can be adjusted in combination.
- 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 run adjustable.
- 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.
- an opening of the wear surface is meant a hole in the wear surface which is completely surrounded by the wear surface.
- a recess of the wear surface is not completely surrounded by the wear surface.
- 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 -, the lateral guidance are made again by the Schlnd lake.
- the provision of Schlnd Economics guide rollers thus has the advantage that, depending on the thickness of the metal strip to be guided between leadership by SchlndMech guide rollers and leadership by means of wear bodies can be selected. 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 Schlchromat Economics-leadership roles and leadership by means of wear bodies.
- the wearer body guide roller In the so-called guiding position, the wearer body guide roller is suitable for laterally guiding the metal band running over the metal belt conveyor. 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.
- the wear body guide roller is attached to or on a wear body; Preferably, it is adjustable by turning the Schlauerpian 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.
- the roller surface of the wear body guide roller 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 protrudes at least partially from this wear surface.
- the roller surface of the wear body guide roller lies in the parking position, as seen from the edge of a metal band to be guided in the direction of the wear surface, beyond 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.
- 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 Schlauer redesign guide rollers and is guided primarily by them instead of by the Schlmony Diagram.
- the axis of rotation of the Schl constitution sciences guide rollers is preferably such that the Schl constitution 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.
- the axis of rotation of the wear body guide roller is substantially perpendicular to the direction of the metal strip.
- the Schl. Economics leadership can be adjusted, for example, by moving, or unfolding or folding, or twisting from the parking position in the leading position or back.
- 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.
- the axis of rotation of the wear body guide rollers is preferably such that the wear body guide rollers are caused to rotate by contact with the metal band. 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.
- the axis of rotation of the wear body guide roller is substantially perpendicular to the direction of the metal strip.
- Another object of the present application is a method for the lateral guidance of running over a metal belt conveyor metal bands by means of a device for laterally guiding a metal strip comprising at least one main body module with a guide plane and at least one wear body with a substantially planar wear surface, characterized in that after a first metal band has passed through the metal belt conveyor and before a second metal belt enters the metal belt conveyor, the wear body controlled from a first defined rotational position to a second defined rotational position is rotated, wherein the wear surface in all defined rotational positions is parallel to the guide plane.
- 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.
- first metal band and second metal band mean only that it is 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, ten metal bands may first 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 more metal bands. While metal band eleven through metal band twenty pass through the device, no rotation occurs.
- the method is characterized in that after a first side guiding phase on at least one side of the metal strip by means of basic body module, and optionally wear bodies and / or wear body guide rollers, in a subsequent second side guiding phase, the lateral guidance on at least one side of the metal strip takes place only by means of wear bodies.
- 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 called here the first lateral guidance phase.
- a second phase of the lateral guidance is called here second lateral guidance phase.
- phase 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.
- 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.
- the wear bodies or wear surfaces can be adjusted, for example, to the guiding position - in which they take over the sole band guide - as soon as the band head of the metal band has passed the lateral guidance device, because then there is no longer any danger that its corners will stick.
- the wear of the main body module is then significantly reduced for the majority of the tape length.
- the device for laterally guiding a metal strip also comprises at least one wear body guide roller.
- a wear body guide roller or a plurality of wear body guide rollers can only lead laterally by means of wear body guide rollers.
- 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.
- 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.
- 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.
- 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.
- 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.
- wear body guide rollers it is sometimes advantageous to have a guiding function of wear body guide rollers.
- the method according to the invention proceeds such that lateral guidance takes place on at least one side of the metal strip by means of several wear bodies during the second side guide phase, during which at least one wear body moves away from the metal strip while losing the contact of its wear surface with the metal strip becomes, then this wear body is rotated around a rotation axis controlled into a new defined rotational position, and then this Schllustchan is again adjusted by building contact of their wear surface with the metal strip to the metal strip out.
- 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.
- the type of lateral guidance between sliding guide is changed by means of wear bodies and rolling guide by means of rollers.
- the rollers may be wearer guide rollers or other guide rollers.
- the type of lateral guidance between sliding guide and rolling guide is changed during the lateral guidance of a metal strip.
- One step may be to turn the wear bodies to a new defined rotational position, or to move, unfold or fold, or twist wearer guide rollers or other guide rollers.
- 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 guide rollers.
- 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 Schlschreibologyn 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 Schlauer stresses can be made easily and cheaply.
- FIG. 1 schematically shows a conventional device 1 for the lateral guidance of a running over a roller table metal strip 2 laterally from above.

Description
Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zur seitlichen Führung eines über eine Metallband-Fördervorrichtung laufenden Metallbandes umfassend zumindest ein Grundkörpermodul mit einer im Wesentlichen vertikalen Führungsebene.The present invention relates to a device for laterally guiding a metal belt running over a metal belt conveyor comprising at least one main body module with a substantially vertical guide plane.
Bei der Herstellung von Metallbändern werden diese mittels Metallband-Fördervorrichtungen, beispielsweise Rollgängen, zu Bearbeitungsmaschinen - beispielsweise Haspelvorrichtungen - geleitet, wo sie aufgewickelt werden. Dabei ist es notwendig, die Metallbänder einer seitlichen Führung zu unterwerfen. Speziell vor Beginn des Aufwickelns ist das erforderlich, um auf dem gewickelten Bund den Versatz der einzelnen Windungen so gering wie möglich zu halten um eine gleichmäßige Seitenfläche zu erreichen. Vorrichtungen zur seitlichen Führung werden beispielsweise Führungslineale oder Einlauflineale genannt. Die Kanten des laufenden Metallbandes, auf welche die Vorrichtungen zur seitlichen Führung einwirken, verursachen an den - auf den Führungslinealen beziehungsweise Einlauflinealen befestigten - Schleißleisten beziehungsweise deren Schleißflächen einen großen Verschleiß. Die mit hohen seitlichen Kräften geführten Bandkanten schneiden sich speziell bei dünneren Bändern unter Funkenflug über die komplette Bandlänge - welche über 2000 m lang sein kann - in diese Schleißleisten ein. Die Schleißflächen der Schleißleisten müssen abhängig vom Produktionsprogramm daher wöchentlich mehrmals erneuert werden.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 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.
Es ist bekannt, zur Verminderung des Aufwandes dabei nicht immer die gesamten Schleißleisten der Führungslineale auszutauschen, sondern beispielsweise durch Verschieben der Schleißleisten dem einschneidenden Band neue Führungsflächen auszusetzen; das ist beispielsweise in
In einer Abwandlung dieser Strategie ist in
Um ein Einfädeln dünner Metallbänder zwischen den Rollgangsrollen zu vermeiden, werden üblicherweise die Achsabstände der Rollgangsrollen so gering wie möglich gehalten, weshalb die herausragenden Bereiche sehr schmal und damit die Führungslängen der einzelnen herausragenden Bereiche sehr kurz sind. Zwischentische, welche den Rollgangsrollenabstand und die Führungslänge vergrößern würden, werden meist vermieden, um das Einfädeln des Bandkopfes zu vermeiden und fertig gewalzte Bandunterseite nicht zu beschädigen.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 der
Die
Es ist die Aufgabe der vorliegenden Erfindung, eine Vorrichtung und ein Verfahren zum Betrieb der Vorrichtung vorzustellen, welches den Aufwand zum Austausch verschlissener Teile reduziert und für alle Metallband-Dicken geeignet ist, ohne die genannten Nachteile aufzuweisen.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.
Diese Aufgabe wird gelöst durch eine
Vorrichtung zur seitlichen Führung eines über eine Metallband-Fördervorrichtung laufenden Metallbandes umfassend
zumindest ein Grundkörpermodul mit einer im Wesentlichen vertikalen Führungsebene, dadurch gekennzeichnet, dass
zumindest ein kontrolliert in mehrere definierte Drehpositionen drehbarer Schleißkörper mit Schleißfläche vorhanden ist,
und
die Schleißfläche im Wesentlichen plan und in allen definierten Drehpositionen parallel zur Führungsebene ist.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 having a substantially vertical guide plane, characterized in that
at least one wear body with a wear surface, which is rotatable in a plurality of defined rotary positions, is present,
and
the wear surface is essentially flat and parallel to the guide plane in all defined rotational positions.
Die Metallband-Fördervorrichtung ist beispielsweise ein Rollgang, beispielsweise ein Rollgang einer Bandhaspelanlage. Die Förderebene der Metallband-Fördervorrichtung ist in der Regel im Wesentlichen horizontal ausgerichtet.The metal belt conveyor device is, for example, a roller table, for example a roller table of a belt coiler. The conveying plane of the metal belt conveying device is generally aligned substantially horizontally.
Das Metallband ist beispielsweise ein Stahlband oder ein Aluminiumband.The metal strip is for example a steel strip or an aluminum strip.
Das Grundkörpermodul mit Führungsebene ist beispielsweise ein sogenanntes Führungslineal oder Einlauflineal, das eine zur Führung des Metallbandes geeignete Fläche, die Führungsebene, aufweist. Sie kann beispielsweise von einer- oder mehreren - auf einem Stützkörper befestigten Verschleißplatte(n) gebildet sein; Stützkörper und Verschleißplatte(n) zusammen bilden dann das Grundkörpermodul.
Die Vorrichtung zur seitlichen Führung kann ein Grundkörpermodul umfassen oder mehrere Grundkörpermodule. Beispielsweise zwei Grundkörpermodule, zur Führung an einer Seite des Metallbandes jeweils eines.
Die Führungsebene dient zur seitlichen Führung des Metallbandes mittels Kontakt mit den Seiten des Metallbandes. Sie begrenzt die Bewegungsfreiheit des Metallbandes in ihre Richtung, wodurch das Metallband seitlich geführt wird.
Die Führungsebene ist im Wesentlichen vertikal ausgerichtet.The main body module with guide level is, for example, a so-called guide ruler or run-in ruler, which is suitable for guiding the metal strip Surface, the management level has. It may, for example, be formed by one or more wear plates (s) 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 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.
The management level is essentially vertical.
Neben dem Grundkörpermodul umfasst die Vorrichtung zur seitlichen Führung auch zusätzlich zumindest einen Schleißkörper mit Schleißfläche.
Der Schleißkörper ist ein Körper, der infolge der Führung des Metallbandes Verschleiß unterliegt, und zwar an einem Bereich, der als Schleißfläche bezeichnet wird.
Der Schleißkörper ist ein anderes Bauteil als das Grundkörpermodul, kann aber in das Grundkörpermodul eingesetzt beziehungsweise an ihm befestigt sein.
Der Schleißkörper besitzt zumindest eine Schleißfläche; diese ist bei Führung des Metallbandes dem Metallband zugewendet und verschleißt durch Kontakt mit dem Metallband im Zuge der seitlichen Führung des Metallbandes.
Das Metallband schneidet sich in den Schleißkörper ein - beispielsweise bei einem Stahl-Warmband, welches mit einer Temperatur von etwa 600°C und einer Geschwindigkeit von circa 60 km/h geführt werden muss -, was grundsätzlich ein gewünschter Effekt ist, denn die eingeschnittenen Konturen verstärken den Führungseffekt für das Metallband. Nach einer Variante kann das Material des Schleißkörpers, oder zumindest seiner Schleißfläche, bezüglich seiner Härte so ausgewählt werden, dass einerseits das Einschneiden von die Führung verbessernden Konturen gefördert, und andererseits die Austauschintervalle in akzeptablem Ausmaß gehalten werden.
Nach einer Ausführungsform weist zumindest ein Schleißkörper zumindest ein Trägermaterial mit einer Beschichtung auf.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 due to the guidance of the metal strip, at a region called the 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, 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, 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.
Es kann beispielsweise ein Trägermaterial oberflächenbeschichtet sein - beispielsweise keramisch, pulverbeschichtet, aufgeschweißt; beispielsweise mit einem Material, dass verschleißbeständiger ist als das Trägermaterial. Es kann auch auf einem Trägermaterial eine Platte aus einem, gegebenenfalls vom Trägermaterial verschiedenen, Material aufgebracht sein, beispielsweise durch Aufschrauben.
Eine Beschichtung, beispielsweise Oberflächenbeschichtung, des Trägermaterials kann auch aus mehreren Schichten aus verschiedenen Materialien bestehen. Beispielsweise kann eine äußere Schicht relativ weich sein, um ein Einschneiden des Metallbandes zu erleichtern zwecks Ausbildung von Führungsrillen, und eine zwischen dieser äußeren Schicht und dem Trägermaterial liegende Schicht relativ hart sein, was ein tieferes Einschneiden erschwert.
Beschichtung, beispielsweise Oberflächenbeschichtung, kann, je nach gewünschter Nutzung, am Schleißkörper überall gleich sein oder segmentweise verschieden sein. Nach einer Ausführungsform sind die Schleißkörper derart symmetrisch, dass sie nach Verschleiß einer Seite einfach umgedreht werden können und damit eine andere gleich ausgeprägte Seite dem Metallband zugewendet und verschlissen wird.For example, a carrier material may be surface-coated - for example ceramic, powder-coated, welded on; For example, with a material that is more resistant to wear than the substrate. It can also be on a carrier material a plate of a, possibly different from the carrier material, be applied, 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, can be the same everywhere on the wear body or segmentally different, depending on the desired use. According to one embodiment, the wear bodies are so symmetrical that they can be easily turned over after one side wear and thus another equally pronounced side facing the metal band and worn.
Die Schleißfläche ist im unverschlissenen Zustand im Wesentlichen plan. Dabei ist mit umfasst, dass der Schleißkörper in der Schleißfläche auch von vornherein - also vor Inbetriebnahme, im unverschlissenen Neuzustand - Führungskonturen zur Führung des Metallbandes aufweisen kann, welche durch das Einschneiden des Metallbandes während des Betriebes noch vertieft werden. Bevorzugt ist sie jedoch in unverschlissenem Zustand plan ohne solche Führungskonturen ausgeführt.
Die Schleißfläche ist der Bereich des Schleißkörpers, der im Betrieb für die Führung des Metallbandes vorgesehen ist. Selbstverständlich kann der sogenannte Schleißkörper auch Bereiche haben, die im Betrieb nicht mit dem Metallband in Berührung kommen werden, beispielsweise aufgrund ihrer Entfernung von der pass-line des Rollgangs beziehungsweise der durch die Oberkante der Rollgangsrollen definierten Ebene.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 area of the wear body that 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.
Der Schleißkörper kann rund sein oder andere Konturen haben. Er kann auch ausgebildet sein wie ein Rad mit Speichen, wobei entsprechend die Felge des Rades die Schleißfläche enthalten beziehungsweise bilden, und die Speichen die Felge auf einer Drehachse fixieren.The wear body may be round or have other contours. It can also be designed as a wheel with spokes, wherein according to the rim of the wheel contain the wear surface or form, and the spokes fix the rim on a rotation axis.
Der Schleißkörper kann auch seitlich angefast sein zur Vermeidung der Gefahr eines Spießens des Metallbandes am Rand des Schleißkörpers; wenn der Schleißkörper eine Scheibe ist also beispielsweise zwischen Seitenfläche und Grundfläche der Scheibe.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.
Der Schleißkörper kann, bevorzugt außerhalb der Schleißfläche, Führungserhebungen aufweisen. In der Praxis zeigt sich, dass Metallbänder dazu neigen können, an den Schleißkörpern hochzulaufen, also ihren Abstand vom untersten Ende des Schleißkörpers zu vergrößern. Um so ein unerwünschtes Hochlaufen zu vermeiden, können Führungserhebungen am Schleißkörper vorgesehen sein, die ein Hochlaufen und Verlassen der am Schleißkörper vorgesehenen Schleißfläche verhindern und gegebenenfalls das Metallband wieder nach unten lenken.
Solche Führungserhebungen können, beispielsweise mehrere, diskrete Erhebungen aus einer Fläche des Schleißkörpers, die in einer Ebene mit der Schleißfläche liegt, sein; also voneinander getrennte einzelne Erhebungen aus einer Ebene. Oder der Schleißkörper ist derart ausgeführt, dass an einem Rand der Schleißfläche neben der Schleißfläche eine Erhebung gegenüber der Ebene der Schleißfläche vorhanden ist, wobei diese Erhebung entweder an diesem gesamten Rand vorhanden ist, oder Unterbrechungen aufweist, also nur teilweise an dem Rand vorhanden ist. Die Erhebung ist dabei vorzugsweise derart ausgeführt, dass sie nicht abrupt aus der Ebene der Schleißfläche auf eine fixe Höhe aufsteigt, sondern ihre Höhe mit zunehmendem Abstand vom Rand der Schleißfläche zunimmt, genannt Anlaufschräge.
Eine Führungserhebung, speziell eine solche Anlaufschräge, verengt im Betrieb den seitlichen Platz für das Metallband. Die Verengung setzt dem Hochlaufen des Metallbandes einen Widerstand entgegen.The wear body can, preferably outside of 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 which is 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-on slope, narrows the lateral space for the metal strip during operation. The constriction sets resistance to the run-up of the metal strip.
Der Schleißkörper ist kontrolliert in mehrere definierte Drehpositionen drehbar. Er kann also zumindest zwei definierte Drehpositionen einnehmen, zwischen denen der Betreiber gezielt auswählen und das Drehen entsprechend kontrolliert steuern und/oder regeln kann.The wear body is controlled rotatable in several defined rotational positions. 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.
Bevorzugt sind mehrere Schleißkörper vorhanden. Dadurch kann Führung in zunehmendem Maße durch die Schleißkörper erfolgen.
Bevorzugt sind alle Schleißkörper erfindungsgemäß ausgeführt. Dadurch wird ein maximaler Nutzen aus den mit der erfindungsgemäßen Vorrichtung verbundenen Vorteilen gezogen.Preferably, several wear bodies are present. As a result, guidance can increasingly take place through the wear bodies.
Preferably, all wear bodies are designed according to the invention. As a result, a maximum benefit is drawn from the advantages associated with the device according to the invention.
Im Vergleich zur
Gegenüber der
Opposite the
Vorzugsweise sind die Schleißkörper austauschbar, so dass bei übermäßigem Verschleiß dieser Bauteile einfach ersetzt werden kann. Ein demgegenüber aufwendigerer Austausch der Grundkörpermodule -beziehungsweise von Teilen der Grundkörpermodule wie beispielsweise Verschleißplatten - ist seltener notwendig. Das erspart Aufwand und Kosten bei der Instandhaltung der Vorrichtung zur seitlichen Führung.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.
Nach einer Ausführungsform sind mehrere in mehrere definierte Drehpositionen drehbare Schleißkörper mit Schleißfläche vorhanden, und zumindest einer dieser Schleißkörper ist unabhängig von anderen Schleißkörpern drehbar. Dadurch kann beim Exponieren neuer Bereiche auf das Ausmaß des Verschleißes individueller Schleißkörper Rücksicht genommen und individuell je nach Bedarf gedreht werden. Das kann den Erneuerungsaufwand für verbrauchte Schleißkörper weiter senken.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 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.
Nach einer Ausführungsform sind mehrere in mehrere definierte Drehpositionen drehbare Schleißkörper mit Schleißfläche vorhanden, und zumindest einer dieser Schleißkörper ist abhängig von zumindest einem anderen dieser Schleißkörper drehbar. Dadurch kann beim Exponieren neuer Bereiche auf das Ausmaß des Verschleißes von Gruppen von zumindest zwei Schleißkörpern Rücksicht genommen werden, und solche Gruppen je nach Bedarf gedreht werden. Das kann den Erneuerungsaufwand für verbrauchte Schleißkörper weiter senken.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. As a result, when exposing new areas to the extent of wear of groups of At least two abrasive bodies are taken into account, and such groups are rotated as needed. This can further reduce the renewal effort for worn wear bodies.
Ein Schleißkörper ist drehbar um eine Drehachse. Wenn der Verschleiß eines Bereiches der Schleißfläche des Schleißkörpers ein akzeptables Ausmaß übersteigt, kann der Schleißkörper kontrolliert um die Drehachse gedreht werden, wodurch ein noch unverbrauchter Bereich der Kante des Metallbandes zugewendet und durch sie verschlissen wird. Durch mehrfaches kontrolliertes Drehen kann die Notwendigkeit zum Austausch der Schleißfläche beziehungsweise des Schleißkörpers verzögert werden, da immer neue, noch nicht verschlissene Bereiche der Kante des Metallbandes zugewendet werden.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.
Bevorzugt ist der Schleißkörper bezüglich seines in Richtung Drehachse gesehenen Umfangs im Wesentlichen drehsymmetrisch, besonders bevorzugt rotationssymmetrisch. Dabei ist mit umfasst, dass der Schleißkörper an seinem Rand Ausnehmungen hat, die einen derartigen Umfang streckenweise unterbrechen.
Das hat bei drehsymmetrischen Schleißkörpern den Vorteil, dass bei Drehung um 360/n Grad - wobei n die Zähligkeit der Drehsymmetrie ist - das Ausmaß der seitlichen Führung durch die Schleißkörper -im Sinne von Kontakt zwischen Metallband und Schleißfläche - im Wesentlichen unbeeinflusst davon bleibt, ob und wie oft der Schleißkörper ausgehend von einer Ausgangsposition um 360/n Grad verdreht wurde - die Länge, über die geführt wird - die Führungslänge - bleibt immer gleich.
Bei rotationssymmetrischen Schleißkörpern gilt das entsprechend, sogar unabhängig vom Drehwinkel.With regard to its circumference seen in the direction of the rotation axis, the wear body is preferably substantially rotationally symmetrical, 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 lateral guidance by the wear bodies - in the sense of contact between metal band and wear surface - is substantially 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 - remains the same.
With rotationally symmetrical wear bodies this applies accordingly, even independently of the angle of rotation.
Ganz besonders bevorzugt ist der Schleißkörper eine runde Scheibe, deren Grundfläche die Schleißfläche des Schleißkörpers bildet, und die um eine Drehachse senkrecht zu ihrer Schleißfläche verdrehbar ist, wobei die Drehachse im Mittelpunkt der runden Scheibe liegt. Der Schleißkörper ist in diesem Fall rotationssymmetrisch bezüglich der Drehachse. Auf diese Weise wird das Metallband unabhängig davon, in welcher Drehposition sich der Schleißkörper befindet - das heißt also, unabhängig davon, um wie viel Grad er ausgehend von einer Ausgangsposition verdreht wurde -von der Schleißfläche immer über eine gleiche Länge geführt. Das Ausmaß der seitlichen Führung durch den Schleißkörper im Sinne von Kontakt zwischen Metallband und Schleißfläche bleibt also im Wesentlichen unbeeinflusst davon, wie sehr der Schleißkörper ausgehend von einer Ausgangsposition verdreht wurde. Selbstverständlich kann die Länge, über die das Metallband von der Schleißfläche geführt wird, aufgrund anderer Faktoren leicht variieren - beispielsweise kann sie je nachdem, ob das Metallband in vorhandene Einschnitte in der Schleißfläche gerät und ihm dadurch eine leichte Änderung der Laufrichtung aufgezwungen wird, leicht variieren.
Der Schleißkörper kann auch andere Formen haben als eine runde Scheibe zu sein, beispielsweise eine vieleckige Scheibe - beispielsweise eine sechseckige Scheibe.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 metal band and wear surface Thus, it 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.
Nach einer bevorzugten Ausführungsform ist zumindest ein Schleißkörper in einer Ausnehmung des zumindest einen Grundkörpermodules anordenbar. Wenn der zumindest eine Schleißkörper in einer Ausnehmung des zumindest einen Grundkörpermodules angeordnet ist, ist es möglich, eine gleichzeitige Führung des Metallbandes durch das Grundkörpermodul und den Schleißkörper vorzunehmen - beispielsweise wenn die Schleißfläche des Schleißkörpers nicht über die Führungsebene des Grundkörpermoduls hinausragt, sondern zumindest teilweise in ihr liegt. Wenn die Schleißfläche wie erfindungsgemäß gefordert im Wesentlichen plan ist und parallel zur Führungsebene liegt, kann das der Fall sein, denn parallel zur Führungsebene umfasst auch in einer Ebene mit der Führungsebene. Oder wenn die Schleißfläche des Schleißkörpers nicht über die Führungsebene des Grundkörpermoduls herausragt und nicht in ihr liegt, sondern vom Metallband weiter entfernt ist als die Führungsebene des Grundkörpermoduls - und zwar dann, wenn das Metallband sich so weit in das Grundkörpermodul einschneidet, dass es auch mit der Schleißfläche in Kontakt kommt und dadurch geführt wird.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.
Bevorzugt ist die Ausnehmung rund. Das ermöglicht einfaches Verdrehen eines in dieser Ausnehmung angeordneten Schleißkörpers, wenn diese bezüglich seiner Drehachse drehsymmetrisch oder rotationssymmetrisch ist.
Wenn die Ausnehmung nicht vollständig vom Grundkörpermodul umschlossen ist, folgt in dieser Ausführungsform der Rand der Ausnehmung im Grundkörpermodul einem Teil eines Kreises.
Die Ausnehmung kann auch andere Formen haben.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.
Bevorzugtermaßen ist der Schleißkörper- und gegebenenfalls die Ausnehmung - so angeordnet, dass der unter die Rollgangsoberkante eintauchende Teil möglichst groß ist.Preferred dimensions of the Schleißkörper- and possibly the recess - arranged so that the submerged below the upper edge of the roller conveyor is as large as possible.
Das Metallband läuft im wesentlichen entlang der Rollgangsoberkante; je größer der Teil des Schleißkörpers - speziell eines rotationssymmetrischen Schleißkörpers, und ganz besonders einer runden Scheibe als Schleißkörper, der unter die Rollgangsoberkante eintaucht, ist, desto größer ist die von dem Schleißkörper dem Metallband zur Führung dargebotene Länge, was eine bessere Führung bewirkt.
Im Falle eines runden Schleißkörpers und einem Rollgang mit Rollgangrollen als Metallband-Fördervorrichtung ist es daher bevorzugt, dass die Drehachse für die drehbaren Schleißkörper über der Mitte zwischen den Drehachsen der Rollgangsrollen liegt. Dann ist die für den betreffendes Schleißkörper in dem betreffenden Rollgang die Realisierung einer maximalen Führungslänge möglich, denn in so einem Fall kann der Schleißkörper tiefer in den Zwischenraum zwischen den Rollgangsrollen eintauchen als wenn die Drehachse bezüglich der Mitte zwischen den Rollgangsrollen seitlich versetzt wäre.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 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 metal belt conveyor, 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.
Besonders bevorzugt ist eine Ausführungsform, in der in einer runden Ausnehmung der Schleißkörper als runde Scheibe, deren Grundfläche die Schleißfläche des Schleißkörpers bildet, und die um eine Drehachse senkrecht zu ihrer Schleißfläche verdrehbar ist, wobei die Drehachse im Mittelpunkt der runden Scheibe liegt, ausgeführt ist, wobei bevorzugt der Schleißkörper passgenau - selbstverständlich mit geringem Spalt, um eine Drehbewegung zu ermöglichen - in der Ausnehmung angeordnet ist. Dann besteht nur eine geringe Gefahr, dass Kanten des Bandkopfes sich an Spalten zwischen Schleißkörper und Führungsebene spießen, und das Verdrehen des Schleißkörpers lässt sich ohne Notwendigkeit zusätzlicher Bewegungen des Schleißkörpers bewerkstelligen. Bei einem als Vieleck-Scheibe ausgebildeten Schleißkörper in einer passgenauen Ausnehmung wäre beispielsweise ein Verdrehen des Schleißkörpers nur möglich, nachdem der Schleißkörper aus der Führungsebene herausbewegt wird, nach dem Verdrehen müsste sie wieder in die Führungsebene hineinbewegt werden. Das kostet Zeit und erfordert geeignete Antriebsaggregate. Von Vorteil ist bei einer Vieleck-Scheibe in einer passgenauen Ausnehmung, dass praktisch eine Sicherung gegen ein unbeabsichtigtes Verdrehen des Schleißkörpers besteht - also definierte Drehpositionen durch die Form der Ausnehmung definiert sind.
Wenn die Ausnehmung ein Verdrehen ohne solches Herausbewegen/Hineinbewegen ermöglichen soll, muss zwischen dem Rand der Ausnehmung und der Vieleck-Scheibe ein genügend großer Spalt vorhanden sein. Das hat den Nachteil, dass Ecken eines Bandkopfes sich an solchen Spalten spießen können.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 precisely - 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 exist 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.
Nach einer Ausführungsform umfasst die erfindungsgemäße Vorrichtung zumindest einen Schleißkörper, für den der Abstand seiner Schleißfläche von der Führungsebene des Grundkörpermoduls verstellbar ist. Damit kann der Schleißkörper oder das Grundkörpermodul bezüglich Abstand zu einem zu führenden Metallband in verschiedene Positionen eingestellt werden. Beispielsweise kann, wenn der Schleißkörper das Metallband berührt, der Abstand ihrer Schleißfläche von der Führungsebene des Grundkörpermoduls beispielsweise dadurch verändert werden, dass das Grundkörpermodul von dem Metallband wegbewegt wird. Bei einer anderen Variante wird der Schleißkörper so in Richtung Metallband bewegt, dass sich der Abstand ihrer Schleißfläche von der Führungsebene des Grundkörpermoduls vergrößert, beispielsweise so lange, bis der Schleißkörper Kontakt mit dem Metallband hat; dabei vermindert sich eine seitliche Bewegungsfreiheit für das Metallband immer mehr.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 base 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 einer sogenannten Führungsposition liegt zumindest ein Teil des Schleißkörpers außerhalb der Führungsebene des Grundkörpermoduls, und zwar in Richtung der zu führenden Kante des Metallbandes. Sie befindet sich also näher am zu führenden Metallband als das Grundkörpermodul; dann wird die seitliche Führung des Metallbandes in erster Linie von diesem Teil des Schleißkörpers beziehungsweise ihrer Schleißfläche durchgeführt, und nicht von der Führungsebene des Grundkörpermoduls. Auf diese Weise wird das teuer und aufwendig zu fertigende Grundkörpermodul erheblich weniger stark verschlissen, es unterliegt abgesehen vom Einlauf des Bandkopfes nahezu keinem Verschleiß.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.
Die Schleißkörper können beispielsweise in die Führungsposition - in welcher sie die alleinige Bandführung übernehmen - eingestellt werden, sobald der Bandkopf des Metallbandes die Vorrichtung zur seitlichen Führung passiert hat, denn dann besteht keine Gefahr mehr, dass seine Ecken sich spießen. Der Verschleiß des teuren Grundkörpermoduls wird dann erheblich vermindert, stattdessen verschleißt erfindungsgemäß der günstig herstellbare Schleißkörper.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.
Beim Einlauf des Bandkopfes würde bei Schleißkörpern in Führungsposition die Gefahr bestehen, dass sich die Ecken des Bandkopfes an diesen Schleißkörpern spießen. Für so eine Phase können die Schleißkörper so verstellt werden - beispielsweise durch Einfahren in Ausnehmungen des Grundkörpermoduls - dass sie nicht aus der Führungsebene hervorragen und daher keine Gefahr besteht, dass ein Bandkopf seine Ecken an Erhebungen aus der Führungsebene spießen kann.
In einer sogenannten Grundkörperposition kann der Schleißkörper gegebenenfalls zusammen mit der Führungsebene des Grundkörpermoduls die seitliche Führung des Metallbandes übernehmen. Das Metallband wird in diesem Fall sowohl die Führungsebene des Grundkörpermoduls als auch die Schleißfläche der Schleißkörper verschleißen.At the inlet of the tape head would be in the case of wear bodies in leadership position the risk that the corners of the tape head spit on these wear bodies. For such a phase, the Schleißkörper can be adjusted so - for example, by retracting into recesses of the main body module - that they are not from the Project 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 optionally 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.
Der Schleißkörper kann beispielsweise dadurch verstellt werden, dass er aus der Führungsebene durch eine Bewegung senkrecht zur Führungsebene hinausgeschoben wird - mittels entsprechender Verstellvorrichtungen. Wenn er senkrecht verschoben wird, liegt in der Führungsposition die gesamte Schleißfläche außerhalb der Führungsebene, und alle Punkte der Schleißfläche haben den gleichen Abstand zur Führungsebene, was einen gleichmäßigen Verschleiß durch das Metallband begünstigt.
Ein senkrecht zur Führungsebene erfolgendes Verschieben ist beispielsweise dann besonders bevorzugt, wenn es sich bei dem Schleißkörper um eine runde Scheibe handelt, deren Grundfläche die Schleißfläche des Schleißkörpers bildet, und die um eine Drehachse senkrecht zu ihrer Schleißfläche verdrehbar ist, wobei die Drehachse im Mittelpunkt der runden Scheibe liegt. Dabei erfolgt das Verschieben in Richtung der Drehachse, welche auch senkrecht zur Führungsebene steht. Eine derartige Ausführungsform ist besonders einfach zu bauen.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.
Nach einer speziellen Ausführungsform davon ist für zumindest einen Schleißkörper unabhängig von anderen Schleißkörpern der Abstand seiner Schleißfläche von der Führungsebene des Grundkörpermoduls verstellbar.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.
Dadurch ist es möglich, die Zahl der seitliche Führung gebenden Schleißkörper zu variieren, beispielsweise je nach Anforderungen des geführten Metallbandes. Dadurch kann gezielt auf Führungsbedarf mittels Führungsebene oder Schleißkörper in speziellen Bereichen der Vorrichtung Rücksicht genommen werden, und in solchen Bereichen individuell pro Schleißkörper verstellt werden. Damit kann der Verschleiß nicht unbedingt benötigter Schleißkörper vermindert und damit der notwendige Instandhaltungsaufwand um ein vielfaches minimiert werden.
Bevorzugt sind alle Schleißkörper so ausgeführt.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.
Nach einer anderen Ausführungsform davon sind mehrere Schleißkörper, für die der Abstand ihrer Schleißfläche von der Führungsebene des Grundkörpermoduls verstellbar ist, vorhanden, wobei er bei zumindest einem dieser Schleißkörper abhängig von zumindest einem anderen dieser Schleißkörper verstellbar ist.
Dadurch kann gezielt auf Führungsbedarf mittels Führungsebene oder Schleißkörper in speziellen, sich über die Ausdehnung von Gruppen von Schleißkörpern erstreckenden, Bereichen der Vorrichtung Rücksicht genommen werden, und für solche Gruppen je nach Bedarf verstellt werden. Das kann den Erneuerungsaufwand für verbrauchte Schleißkörper weiter senken und macht die Bedienung einfacher und erfordert weniger baulichen Aufwand gegenüber einer Einstellbarkeit unabhängig voneinander.
Bevorzugt sind alle dieser Schleißkörper abhängig von zumindest einem anderen dieser Schleißkörper verstellbar, also alle Schleißkörper im Verbund verstellbar.
Bevorzugt ist der zumindest eine Schleißkörper, für den der Abstand seiner Schleißfläche von der Führungsebene des Grundkörpermoduls verstellbar ist, während des Bandlaufes verstellbar.According to another embodiment thereof, a plurality of wear bodies, for which the distance of their wear surface from the management level of the base 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 adjustability independently.
Preferably, all of these wear bodies are adjustable as a function of at least one other of these wear bodies, that is to say all wear bodies can be adjusted in combination.
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 run adjustable.
Nach einer bevorzugten Ausführungsform weist die Vorrichtung zumindest eine Schleißkörper-Führungsrolle auf, die durch eine Ausnehmung der Schleißfläche eines Schleißkörpers oder eine Öffnung der Schleißfläche eines Schleißkörpers geführt ist und zumindest teilweise aus dieser Schleißfläche hervorragt.
Unter einer Öffnung der Schleißfläche ist zu verstehen ein Loch in der Schleißfläche, das vollständig von der Schleißfläche umgeben ist. Im Gegensatz dazu ist eine Ausnehmung der Schleißfläche nicht vollständig von der Schleißfläche umgeben.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.
Entsprechend kann in der erfindungsgemäßen Vorrichtung bei Bedarf der Vorteil einer seitlichen Führung durch Führungsrollen genutzt werden, und wenn das nicht mehr gewünscht oder notwendig ist - beispielsweise bei dünnen Metallbändern mit Dicken bis 5 mm -, die seitliche Führung wieder von den Schleißflächen geleistet werden.
Das Vorsehen der Schleißkörper-Führungsrollen hat also den Vorteil, dass je nach Dicke des zu führenden Metallbandes zwischen Führung mittels Schleißkörper-Führungsrollen und Führung mittels Schleißkörpern gewählt werden kann. Oder es kann je nachdem, ob Gefahr besteht, Ecken des Bandkopfes zu spießen oder Kanten des Metallbandes zu beschädigen, zwischen Führung mittels Schleißkörper-Führungsrollen und Führung mittels Schleißkörpern gewählt werden.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 -, the lateral guidance are made again by the Schleißflächen.
The provision of 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 by means of wear bodies can be selected. 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.
Nach einer bevorzugten Ausführungsform weist die Vorrichtung zumindest eine Schleißkörper-Führungsrolle auf, die zumindest in
- eine Parkposition
und - eine Führungsposition
- a parking position
and - a leadership position
In der sogenannten Führungsposition ist die Schleißkörper-Führungsrolle geeignet, das über die Metallband-Fördervorrichtung laufende Metallband seitlich zu führen. In der sogenannten Parkposition ist sie nicht dazu geeignet - dann wird das Metallband durch Schleißkörper und/oder die Führungsebene geführt.In the so-called guiding position, the wearer body guide roller is suitable for laterally guiding the metal band running over the metal belt conveyor. 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.
Nach einer Ausführungsform ist die Schleißkörper-Führungsrolle an oder auf einem Schleißkörper befestigt; bevorzugt ist sie dabei durch Verdrehen der Schleißkörper in Parkposition oder Führungsposition einstellbar.
Die Schleißkörper-Führungsrolle kann auch am Grundkörpermodul befestigt sein, oder an anderen Teilen der Vorrichtung, oder an angrenzenden Vorrichtungen.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.
Nach einer bevorzugten Ausführungsform ist in der Führungsposition die Rollenfläche der Schleißkörper-Führungsrolle durch eine Ausnehmung der Schleißfläche eines Schleißkörpers oder eine Öffnung der Schleißfläche eines Schleißkörpers geführt und ragt zumindest teilweise aus dieser Schleißfläche hervor.According to a preferred embodiment, in the guiding position, the roller surface of the wear body guide roller 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 protrudes at least partially from this wear surface.
Nach einer Variante liegt dabei in der Parkposition die Rollenfläche der Schleißkörper-Führungsrolle von der Kante eines zu führenden Metallbandes in Richtung Schleißfläche gesehen jenseits der Schleißfläche. Wenn die Rollenoberfläche der Schleißkörper-Führungsrolle in Richtung der Schleißfläche gesehen jenseits der Schleißfläche - anders ausgedrückt unterhalb der Schleißfläche - liegt, trägt sie nicht zur seitlichen Führung bei. In der Führungsposition ragt die Rollenfläche der Schleißkörper-Führungsrolle zumindest teilweise aus der Schleißfläche hervor - von der Schleißfläche in Richtung von der Führungsebene des Grundkörpermoduls weg gesehen, oder anders ausgedrückt zur Kante eines zu führenden Metallbandes hin gesehen. Das Metallband kommt dann in erster Linie in Kontakt mit den Schleißkörper-Führungsrollen und wird in erster Linie durch sie geführt statt durch die Schleißfläche.According to one variant, the roller surface of the wear body guide roller lies in the parking position, as seen from the edge of a metal band 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.
Dabei liegt die Drehachse der Schleißkörper-Führungsrollen bevorzugt so, dass die Schleißkörper-Führungsrollen durch Kontakt mit dem Metallband in Drehbewegung versetzt werden. Das sorgt für einen geringen Verschleiß der Schleißkörper-Führungsrollen, da zumindest ein Teil der vom Metallband beim Kontakt auf die Schleißkörper-Führungsrolle übertragenen Energie in eine Drehbewegung der Rollen umgesetzt wird, statt zu Verschleißerscheinungen beizutragen. Bevorzugt steht dabei die Drehachse der Schleißkörper-Führungsrolle im Wesentlichen senkrecht zur Laufrichtung des Metallbandes.In this case, 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 direction of the metal strip.
Die Schleißkörper-Führungsrolle kann dabei beispielsweise durch Verschieben, oder Ausklappen beziehungsweise Einklappen, oder Verdrehenaus der Parkposition in die Führungsposition oder zurück eingestellt werden.The Schleißkörper leadership can be adjusted, for example, by moving, or unfolding or folding, or twisting from the parking position in the leading position or back.
Nach einer anderen Variante ragt dabei die Rollenfläche der Schleißkörper-Führungsrolle sowohl in der Parkposition als auch in der Führungsposition von der Schleißfläche in Richtung Metallband gesehen zumindest teilweise aus der Schleißfläche hervor.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.
Durch Verdrehen des Schleißkörpers wird die Position der Öffnung oder Ausnehmung der Schleißfläche und der aus dieser Öffnung oder Ausnehmung hervorragenden Schleißkörper-Führungsrolle geändert. Entsprechend kann durch Verdrehen des Schleißkörpers in eine Position, in der ein zu führendes Metallband mit der Schleißkörper-Führungsrolle in Kontakt kommen und dadurch geführt werden kann, die Führungsposition eingestellt werden. Zwischen Führung mittels Schleißkörper und Führung mittels Schleißkörper-Führungsrollen kann also einfach gewählt werden.By rotating the wear body, the position of the opening or recess of the wear surface and the outstanding from this opening or recess Schleißkörper leadership 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 Führungsposition liegt die Drehachse der Schleißkörper-Führungsrollen bevorzugt so, dass die Schleißkörper-Führungsrollen durch Kontakt mit dem Metallband in Drehbewegung versetzt werden. Das sorgt für einen geringen Verschleiß der Schleißkörper-Führungsrollen, da zumindest ein Teil der vom Metallband beim Kontakt auf die Schleißkörper-Führungsrolle übertragenen Energie in eine Drehbewegung der Rollen umgesetzt wird, statt zu Verschleißerscheinungen beizutragen.In the guiding position, the axis of rotation of the wear body guide rollers is preferably such that the wear body guide rollers are caused to rotate by contact with the metal band. 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.
Bevorzugt steht dabei die Drehachse der Schleißkörper-Führungsrolle im Wesentlichen senkrecht zur Laufrichtung des Metallbandes.Preferably, the axis of rotation of the wear body guide roller is substantially perpendicular to the direction of the metal strip.
In der Parkposition ist der Schleißkörper beziehungsweise die Öffnung in der Schleißfläche so positioniert, dass die aus der Schleißfläche hervorragende Schleißkörper-Führungsrolle nicht mit dem zu führenden Metallband in Kontakt kommt - die Führung des Metallbandes erfolgt durch die Schleißkörper.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.
Entsprechend kann in der erfindungsgemäßen Vorrichtung durch Einstellung der Schleißkörper-Führungsrolle in Führungsposition bei Bedarf der Vorteil einer seitlichen Führung durch Schleißkörper-Führungsrollen genutzt werden, und wenn das nicht mehr gewünscht oder notwendig ist - beispielsweise bei dünnen Metallbändern mit Dicken bis 5 mm -, durch Einstellung der Schleißkörper-Führungsrolle in die Parkposition die seitliche Führung wieder von den Schleißflächen geleistet werden.
Das Vorsehen derartiger Schleißkörper-Führungsrollen hat also den Vorteil, dass je nach Dicke des zu führenden Metallbandes zwischen Führung mittels Schleißkörper-Führungsrollen und Führung mittels Schleißkörpern gewählt werden kann. Oder es kann je nachdem, ob Gefahr besteht, Ecken des Bandkopfes zu spießen oder Kanten des Metallbandes zu beschädigen, zwischen Führung mittels Schleißkörper-Führungsrollen und Führung mittels Schleißkörpern gewählt werden.
Beispielsweise ist bei dicken Metallbändern - beispielsweise mit Dicken über 5mm - die Gefahr, dass die Bandkanten des Bandkopfes durch hervorstehende Rollen beschädigt werden sehr gering oder gar nicht gegeben. Bei dicken Metallbändern wird man daher die Schleißkörper-Führungsrolle noch vor dem Einlaufen des Metallbandes in Führungsposition bringen.
Ebenso ist eine Kombination aus Führung des Metallbandes mit Schleißkörper-Führungsrollen und den Schleißkörper-Führungsrollen vor- oder nachgelagerten Schleißkörpern möglich.Accordingly, in the device according to the invention by adjusting the Schleißkörper guide roller in leadership position, if necessary, the advantage of lateral guidance by Schleißkörper guide rollers are used, and if that is no longer desirable or necessary - for example, in thin metal bands with thicknesses up to 5 mm -, by Setting the wearer roller guide roller in the parking position, the lateral guidance is again provided by the wear surfaces.
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 by means of wear bodies can be selected. 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, 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 you will therefore bring the Schleißkörper-leadership role before entering the metal strip in leadership position.
Likewise, a combination of guiding the metal strip with Schleißkörper guide rollers and the Schleißkörper guide rollers upstream or downstream wear bodies is possible.
Ein weiterer Gegenstand der vorliegenden Anmeldung ist ein Verfahren zur seitlichen Führung von über eine Metallband-Fördervorrichtung laufenden Metallbändern
mittels einer Vorrichtung zur seitlichen Führung eines Metallbandes umfassend zumindest ein Grundkörpermodul mit Führungsebene sowie zumindest einen Schleißkörper mit im Wesentlichen planer Schleißfläche,
dadurch gekennzeichnet, dass
nachdem ein erstes Metallband die Metallband-Fördervorrichtung durchlaufen hat, und bevor ein zweites Metallband in die Metallband-Fördervorrichtung einläuft,
der Schleißkörper kontrolliert von einer ersten definierten Drehposition in eine zweite
definierte Drehposition gedreht wird, wobei
die Schleißfläche in allen definierten Drehpositionen parallel zur Führungsebene ist.Another object of the present application is a method for the lateral guidance of running over a metal belt conveyor metal bands
by means of a device for laterally guiding a metal strip comprising at least one main body module with a guide plane and at least one wear body with a substantially planar wear surface,
characterized in that
after a first metal band has passed through the metal belt conveyor and before a second metal belt enters the metal belt conveyor,
the wear body controlled from a first defined rotational position to a second
defined rotational position is rotated, wherein
the wear surface in all defined rotational positions is parallel to the guide plane.
Es gibt zwei oder mehr definierte Drehpositionen. Die Begriffe erste Drehposition und zweite definierte Drehposition bedeuten lediglich, dass es sich um zwei verschiedene Drehpositionen handelt. Sie bedeuten in diesem Zusammenhang nicht, dass es zwangsweise lediglich zwei Drehpositionen gibt.
Die Begriffe erstes Metallband und zweites Metallband bedeuten lediglich, dass es sich um zwei verschieden Metallbänder handelt. Sie bedeuten in diesem Zusammenhang nicht, dass es zwangsweise lediglich zwei Metallbänder gibt. Sie bedeuten in diesem Zusammenhang nicht, dass zwischen zwei aufeinanderfolgenden Metallbändern zwangsweise immer gedreht wird; ein Drehen kann auch erst stattfinden, nachdem mehrere Metallbänder die Vorrichtung durchlaufen haben, bevor ein weiteres Metallband die Vorrichtung durchläuft; auf dieses weitere Metallband können auch wieder mehrere Metallbänder folgen, bevor erneut ein Drehen stattfindet.
Beispielsweise können zuerst zehn Metallbänder die Vorrichtung durchlaufen, dann erfolgt ein Drehen, bevor ein elftes Metallband als erstes Metallband einer Gruppe von zehn weiteren Metallbändern die Vorrichtung durchläuft. Während Metallband elf bis Metallband zwanzig die Vorrichtung durchlaufen, erfolgt kein Drehen.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 mean only that it is 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, ten metal bands may first 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 more metal bands. While metal band eleven through metal band twenty pass through the device, no rotation occurs.
Auf diese Weise können definiert frische Bereiche der Schleißkörper einem Verschleiß exponiert werden, wobei vorzugsweise die Führungslänge sich nicht durch veränderte Orientierung der Schleißflächen verändert.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.
Nach einer Ausführungsform ist das Verfahren dadurch gekennzeichnet, dass nach einer ersten Seitenführungsphase an zumindest einer Seite des Metallbandes mittels Grundkörpermodul, und gegebenenfalls Schleißkörpern und/oder Schleißkörper-Führungsrollen,
in einer darauffolgenden zweiten Seitenführungsphase die seitliche Führung auf zumindest einer Seite des Metallbandes nur mittels Schleißkörpern erfolgt. Gegebenenfalls umfasst die Vorrichtung zur seitlichen Führung eines Metallbandes auch zumindest eine Schleißkörper-Führungsrolle.
Dabei können bei seitlicher Führung in der zweiten Seitenführungsphase nur mittels Schleißkörpern ein Schleißkörper oder mehrere Schleißkörper seitlich führen.According to one embodiment, the method is characterized in that after a first side guiding phase on at least one side of the metal strip by means of basic body module, and optionally wear bodies and / or wear body guide rollers,
in a subsequent second side guiding phase, the lateral guidance on at least one side of the metal strip takes place 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.
Eine erste Phase der seitlichen Führung wird hier erste Seitenführungsphase genannt.
Eine zweite Phase der seitlichen Führung wird hier zweite Seitenführungsphase genannt.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.
Wie vorab beschrieben, gibt es Phasen der seitlichen Führung für ein zu führendes Metallband, in denen es vorteilhaft ist, ein Metallband mittels der Führungsebene zu führen, ohne dass aus dieser Erhebungen herausragen - beispielsweise beim Einlauf des Bandkopfes. Das verursacht Verschleiß an der Führungsebene. In so einer Phase kann gegebenenfalls auch ein Schleißkörper in Grundkörperposition - also in einer Position, in der er keine Erhebung aus der Führungsebene bildet - zusammen mit der Führungsebene des Grundkörpermoduls die seitliche Führung des Metallbandes übernehmen. Das Metallband wird in diesem Fall sowohl die Führungsebene des Grundkörpermoduls als auch die Schleißfläche des Schleißkörpers verschleißen.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.
Wenn die Notwendigkeit einer solchen seitlichen Führung für das betreffende Metallband vorüber ist - beispielsweise wenn der Bandkopf den Bereich der erfindungsgemäßen Vorrichtung verlassen hat -, wird erfindungsgemäß Verschleiß der Führungsebene vermieden, indem die Führung für den Großteil des Metallbandes nur noch mittels Schleißkörper erfolgt.
Das kann beispielsweise mit der erfindungsgemäßen Vorrichtung mit zumindest einem Schleißkörper, für den der Abstand ihrer Schleißfläche von der Führungsebene des Grundkörpermoduls verstellbar ist, erreicht werden.
Damit kann der Abstand der Schleißfläche von der Führungsebene, und damit auch der Abstand zu dem zu führenden Metallband in eine Position eingestellt werden, in der sie dem Metallband näher ist als die Führungsebene des Grundkörpermoduls - die Führungsposition.
Die Schleißkörper beziehungsweise Schleißflächen können beispielsweise in die Führungsposition - in welcher sie die alleinige Bandführung übernehmen - eingestellt werden, sobald der Bandkopf des Metallbandes die Vorrichtung zur seitlichen Führung passiert hat, denn dann besteht keine Gefahr mehr, dass seine Ecken sich spießen. Der Verschleiß des Grundkörpermoduls wird dann für den Großteil der Bandlänge erheblich vermindert.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, for which the distance of its wear surface from the guide plane of the base body module is adjustable.
Thus, the distance of the wear surface of the guide plane, and thus the distance to the leading metal strip 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 wear bodies or wear surfaces can be adjusted, for example, to the guiding position - in which they take over the sole band guide - as soon as the band head of the metal band has passed the lateral guidance device, because then there is no longer any danger that its corners will stick. The wear of the main body module is then significantly reduced for the majority of the tape length.
Nach einer anderen Ausführungsform ist das Verfahren dadurch gekennzeichnet, dass nach einer ersten Seitenführungsphase an zumindest einer Seite des Metallbandes mittels Grundkörpermodul, und gegebenenfalls Schleißkörpern und/oder Schleißkörper-Führungsrollen,
in einer darauffolgenden zweiten Seitenführungsphase die seitliche Führung auf zumindest einer Seite des Metallbandes auf eine der folgenden Arten erfolgt:
- nur mittels Schleißkörper-Führungsrollen,
- mittels Schleißkörpern und Schleißkörper-Führungsrollen.
in a subsequent second lateral guiding phase, the lateral guidance takes place on at least one side of the metal band in one of the following ways:
- only by means of wear-body guide rollers,
- by means of wear bodies and wear body guide rollers.
In diesem Fall umfasst die Vorrichtung zur seitlichen Führung eines Metallbandes auch zumindest eine Schleißkörper-Führungsrolle.In this case, the device for laterally guiding a metal strip also comprises at least one wear body guide roller.
Dabei können bei seitlicher Führung in der zweiten Seitenführungsphase nur mittels Schleißkörper-Führungsrollen eine Schleißkörper-Führungsrolle oder mehrere Schleißkörper-Führungsrollen seitlich führen.
Dabei können bei seitlicher Führung in der zweiten Seitenführungsphase mittels Schleißkörpern und Schleißkörper-Führungsrollen ein Schleißkörper oder mehrere Schleißkörper, und eine Schleißkörper-Führungsrolle oder mehrere Schleißkörper-Führungsrollen seitlich führen.
Bevorzugt wird nach der ersten Seitenführungsphase zumindest ein Schleißkörper und/oder das zumindest eine Grundkörpermodul in eine Position verstellt, in der die Schleißfläche des Schleißkörpers außerhalb der Führungsebene liegt. Es kann beispielsweise ein Schleißkörper, dessen Schleißfläche während der ersten Seitenführungsphase innerhalb der Führungsebene liegt, weiter in Richtung des zu führendes Metallbandes bewegt werden. Oder es kann das Führungsmodul weiter in Richtung vom zu führenden Metallband weg bewegt werden, so dass der Schleißkörper, der in seiner ursprünglichen Position verbleibt, sich näher beim Metallband befindet als das Führungsmodul.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.
Es erfolgt dabei die seitliche Führung des Metallbandes in der zweiten Seitenführungsphase mittels zumindest einer Schleißkörper-Führungsrolle. Wie vorab beschrieben, ist es bisweilen vorteilhaft, eine Führungsfunktion von Schleißkörper-Führungsrollen übernehmen zu lassen.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.
Nach einer bevorzugten Ausführungsform verläuft das erfindungsgemäße Verfahren so, dass während der zweiten Seitenführungsphase die seitliche Führung auf zumindest einer Seite des Metallbandes mittels mehrerer Schleißkörper erfolgt, wobei während der zweiten Seitenführungsphase zumindest ein Schleißkörper unter Verlust des Kontaktes ihrer Schleißfläche mit dem Metallband vom Metallband weg verstellt wird,
dann dieser Schleißkörper um eine Drehachse kontrolliert in eine neue definierte Drehposition gedreht wird,
und dann dieser Schleißkörper wieder unter Aufbau von Kontakt ihrer Schleißfläche mit dem Metallband zum Metallband hin verstellt wird.
Dadurch ist es möglich, während des Bandlaufes auf verschleißbedingten Bedarf nach Verstärkung der herrschenden Führungsfunktion reagieren zu können. Verschlissene Schleißkörper können während dem Bandlauf in Positionen verdreht werden, in denen noch unverschlissene Bereiche ihrer Schleißfläche dem Metallband exponiert werden.According to a preferred embodiment, the method according to the invention proceeds such that lateral guidance takes place on at least one side of the metal strip by means of several wear bodies during the second side guide phase, during which at least one wear body moves away from the metal strip while losing the contact of its wear surface with the metal strip becomes,
then this wear body is rotated around a rotation axis controlled into a new defined rotational position,
and then this Schleißkörper is again adjusted by building contact of their wear surface with the metal strip to the metal strip out.
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.
Nach einer bevorzugten Ausführungsform wird die Art der seitlichen Führung zwischen gleitender Führung mittels Schleißkörpern und abwälzender Führung mittels Rollen umgestellt. Die Rollen können Schleißkörper-Führungsrollen sein oder andere Rollen zur Führung.According to a preferred embodiment, the type of lateral guidance between sliding guide is changed by means of wear bodies and rolling guide by means of rollers. The rollers may be wearer guide rollers or other guide rollers.
Nach einer Variante wird während der seitlichen Führung eines Metallbandes die Art der seitlichen Führung zwischen gleitender Führung und abwälzender Führung umgestellt. Ein Schritt dabei kann Drehen der Schleißkörper in eine neue definierte Drehposition sein, oder Verschieben, Ausklappen beziehungsweise Einklappen, oder Verdrehen von Schleißkörper-Führungsrollen oder anderen Rollen zur Führung.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 may be to turn the wear bodies to a new defined rotational position, or to move, unfold or fold, or twist wearer guide rollers or other guide rollers.
Nach einer bevorzugten Ausführungsform umfasst die Art der seitlichen Führung sowohl gleitende Führung mittels Schleißkörpern als auch abwälzende Führung mittels Rollen. Die Rollen können Schleißkörper-Führungsrollen sein oder andere Rollen zur Führung.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 guide rollers.
Vorrichtung und Verfahren gemäß der Erfindung erlauben es, den Wartungsaufwand im Vergleich zu herkömmlichen Vorrichtungen deutlich zu vermindern. Es wird der Zeitaufwand für den Austausch verschlissener Teile vermindert, da durch das mehrfache Exponieren noch unverschlissener Bereiche der Schleißfläche eines Schleißkörpers zum Metallband die Schleißkörper seltener als herkömmliche Schleißleisten ausgetauscht werden müssen. Der Austausch kann im Zuge anderer Wartungsstillstände erfolgen, Produktionsausfall infolge eines kurzen Wartungsintervalls für Schleißflächen kann so vermieden werden. Es wird auch der Kostenaufwand für den Austausch von Schleißkörpern gering gehalten, da die Schleißkörper einfach und billig gefertigt werden können.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.
