    description
    Name of the invention
    Drive roller changing system for drivers of a rolling mill plant. Field of technology
    The subject invention relates to a device and a method for changing drive rollers of drivers of a rolling mill.
    State of the art
    In driving devices, also called drivers, metal strip is clamped between a pair of rollers, driven or deflected. Drivers are typically used in rolling mills of rolling mills, such as hot rolling mills, where they are placed in front of rolled reels of the coiler stations to adjust the strip tension in front of the reel by means of two rollers, namely the drive roller and the support drive roller.
    Steering drivers have the additional task of reducing sideways migrations of the rolled strip before reeling. For this purpose, for example, the pivotable drive roller is driven and employed against the stationary Stützreibreibrolle that experiences through the position of the drive roller relative to the Stützreibrolle the rolled strip a desired strip tension and a desired lateral displacement.
    Such steering drivers are known, for example, from EP747147B1 or AT500689B1.
    In EP747147B1 a steering driver is shown, whose pivotable drive roller is arranged between two rockers by means of the two ends of the driving roller axle. Both wings are rigidly connected to a torsion spring of a frame, which forms an axis of rotation for the wings. 2 201113520 • · ft · • ft • * * * * «· • • • * * 4 *
    In AT500689B1 a similar steering actuator is disclosed in which the rockers, however, can be pivoted independently of one another on an axis of rotation of a frame.
    The drive roller and the support drive roller of a steering actuator must be regularly cleaned and polished, as for example by carbon caking, on the reel to be reeled up dirt particles, or caused by tapping surface defects in the reeled tape, the surface of the drive roller and the support roller are uneven, which in turn may cause damage to the surface of the reeled tape.
    In EP747147B1 or AT500689B1, the driving roller axle is mounted on a bearing area of the rocker arms, wherein the driving roller is located below the rocker arm. The bearings of the drive roller, in order to avoid damage during puncture, for example, provided by spring-activated balancing play.
    A removal of the drive roller upwards is not possible, since such removal the rocker is in the way and blocks the way up. For removal to the bottom, right or left in the operating state, the path is blocked by the Stützreibrolle and the frame. Before a removal is possible, therefore, only an obstructed path must be opened.
    In order to facilitate cleaning and polishing of the capstan and Stützreibrolle usually the pair of rollers supporting the swinging pair is pivoted by means of swing cylinders in an intermediate position; this is also necessary to replace the drive roller. The intermediate position is often reached after the pivoting of the pair of rockers by 180 °. Subsequently, the drive roller and the support drive roller in the installed state are usually cleaned and polished or polished dog. Through the 201113520 ** · «» # 3 • t «» * · · · · «« «···· t» ··· · • «·» * * * ·· · »·« ·· »« · «·« * · «« »· · · · · · ·
    Cleaning and grinding or polishing in the system results in a security risk. This is because the people involved have to go inside the plant between the plant parts, which must be reliably turned off and blocked. In addition, there is a safety risk due to the time pressure required to carry out these activities, since the cleaning and grinding or polishing must be carried out in the time required for the work roll change of scaffolding time of 10 to 15 minutes. If, due to cleaning, sanding and polishing, it is not possible to produce a sufficiently uniform surface on the drive roller or support drive roller, or if it is damaged, the drive roller or support drive roller must be removed from the frame after swiveling the swinging arm and replaced with a new drive roller or support drive roller. For this purpose, the entire swing construction including the drive roller must be removed in the case of the steering drivers in accordance with EP747147B1 or AT500689B1. Due to the large number of fasteners to be solved and the mass of the frame together with the drive roller maintenance of drive rollers and Stützreibrollen causes a considerable amount of time. In addition, the drive roller is poorly accessible for maintenance when it is located between the wings.
    According to the state of the art drivers are known which overcome the disadvantages of the prior art and which cause less time consuming work with less safety risks in the change of the driving roller than conventional drivers and methods.
    Such a driver for a steel strip coiler has at least one support drive roller mounted on a frame and at least one drive roller engageable with the support drive roller mounted on at least one rocker connected to the frame, the drive roller being mounted on a bearing area of the rocker, the storage area is open for insertion or 201113520 9 «4 4 4 4 4 444 4 4 4 4 4 4 ··· * · ♦ 9 4 · ι« * · I · * · · 9 4 9 · * · * * * '* · · · · · »· * * * * • • 4 4 4 4 4 ·» M ··
    Removing the drive roller to the side and / or up when the rocker position in operating position, and the driver has a fixing mechanism for fixing the drive roller to the storage area.
    Under the storage area is to be understood the area of the rocker, in which the drive roller is attached to the rocker.
    The storage area is open for insertion or removal of the drive roller to the side and / or upwards in position of the rocker in the operating position, therefore, the storage area is not an expansion of the drive roller to the side and / or up in the way. A drive roller can therefore be removed if necessary to the side and / or up from the rocker, without the rocker with the drive roller substantially remove from the operating position or rocker must be completely dismantled with the drive roller. Operating position is a position of the rocker to be taken, which is taken in normal operation of the driver.
    The driver has a fixing mechanism for fixing the drive roller to the storage area. This ensures during operation that the drive roller does not undesirably break off to the side and / or upwards. In the fixed state, a controlled displacement of the drive roller in different operating positions is possible.
    Preferably, the positioning of the drive roller to the support drive roller in the fixed state by changing the setting of the fixing mechanism in different positions can be changed.
    According to one embodiment, the fixing mechanism comprises a displaceable latch, which is preferably fixable to the rocker.
    According to another embodiment, the fixing mechanism comprises a folding device, the parts of which are provided around 201113520 5 Λ 4 9 · · ** 9 ··· »* ·« · · * · · * * * * · *** · »* · ·« * • * 9 9 9 9 9 9 9 9 ·· at least one axle attached to the rocker can be folded and fixed to the rocker arm. For example, it may be two interlockable arms that are locked by a movable wedge. Each of the arms works on a different axis.
    The support drive roller is located below the drive roller. A removal of the support friction roller up is therefore not possible as long as the drive roller is installed in the driver.
    When the drive roller has been removed, the path for the support drive roller is open for removal upwards.
    When the drive roller is mounted between a pair of rockers, the spacing of the rockers is preferably greater than the length of the support drive roller. This ensures that the support drive roller can be removed by the resulting due to removal of the drive roller free space upwards.
    If the distance of the rockers in the operating position is less than the length of the Stützreibrolle, it is preferred that at least one of the rockers is displaceable or pivotable relative to the other rocker, when the drive roller is removed. In this way it is achieved that the support drive roller can be removed.
    The steel strip coiler is preferably a steel strip coiler for hot strip.
    Preferably, the driver is a steering driver.
    According to a preferred embodiment, the drive roller and the support drive roller are arranged in a holding device.
    The holding device, which may be a holding frame, for example, thus contains both the drive roller and the support drive roller. 201113520 6 • ft M ft «ft Mil · *
    • · «ft · ·« «I ft | I * * * * I * * - * * ft * * * * * ft ································································
    This makes it possible, for removing or for inserting a pair of driving roller and supporting drive roller only to engage the holding device and to have to remove it from the driver.
    Because the drive roller and the support drive roller need not be removed individually or inserted individually into the driver, removal and insertion can be accomplished more quickly.
    The support drive roller can be mounted stationary or displaceable on the frame.
    According to one embodiment, the drive roller axle and / or the support drive roller axle around which the drive roller or the support drive roller rotates consist of at least two drive roller axles and / or
    Support driving roller after parts, wherein at least one of the Treibrollenachsteile as on the cylindrical body of the drive roller or Stützreibreibrolle releasably secured, for example via a connecting flange, a perforated disc with sliding driving pin, or claw coupling - shaft stub is executed. The stub shaft can be designed as a hollow shaft, in which a motor-driven shaft can be inserted to drive the drive roller or the support drive roller.
    This allows for a quick removal of the drive roller and / or Stützreibrolle from the driver, which reduces a caused by time pressure during capstan change security risk.
    According to one embodiment of the driver, the support drive roller is laterally removable from the driver in the direction of its longitudinal axis. It can also be inserted laterally in the direction of its longitudinal axis into the driver.
    In the drivers shown in EP747147B1 or AT500689B1, one end of the rocker arms is pivotable about an axis of rotation, while the other end of the rocker arms is pivoted with an angle of rotation φ
    I ·· # * Φ • * * *
    Actuating device such as a pressure medium cylinder, preferably a hydraulic cylinder, is connected. By adjusting this actuator, the rockers can be pivoted about its axis of rotation, for example, to enable the removal of the drive roller or to control or regulation of the distance of the drive roller and Stützreibrolle.
    The storage area of the drive roller is located between the pivotable end and the end of the rocker connected to the actuating device.
    Also in the driver according to the prior art, the rockers are pivotable about an axis of rotation arranged in a pivot axis of the rocker, and they are connected in an operating region with an actuating device. In this case, the storage area of the drive roller can be located between the axis of rotation range and the actuation area, as in EP747147B1 or AT500689B1.
    According to another embodiment, the axis of rotation range may be between the storage area and the operating area. An advantage of such an embodiment is that when pressing the drive roller forces flow better into the rocker and for the swingarm more favorable stress conditions are generated. The effective distance of an actuating device acting on one end of the rocker can also be structurally more easily increased in such a construction than in the embodiments designed as in EP747147B1 or AT500689B1. By increasing the effective distance equal forces can be achieved with smaller actuators, or achieve greater forces with the same actuators.
    Another internal prior art is a method for removing a drive roller from a driver according to the internal state of the art.
    This procedure is characterized in that it includes the steps of opening the fixing mechanism, removing the drive roller to the side and / or upwards from the... Driver, includes.
    By opening the fixing mechanism is meant that the fixation of the drive roller is solved at the storage area.
    The support drive roller in a driver is held in the driver by fixation devices so as not to change position at all during normal operation or to change position beyond an acceptable level. The support drive roller can be fixed, so that no movement is possible. It may also be displaceable to an acceptable or desired extent. The degree of displaceability that is acceptable or desired depends on the respective operating state. In order to change the deflecting forces of the driver depending on the strip thickness and strip quality, for example, the distance of the axes of the driving roller and the supporting drive roller is variable to a certain extent.
    An embodiment of the method according to the internal prior art is characterized in that, after the removal of the drive roller, it additionally comprises the steps of - releasing fixing devices for fixing the support drive roller in the driver, - removing the support drive roller upwards from the driver.
    By resulting from the removal of the drive roller opening and the support drive roller can be removed upwards from the driver.
    According to another embodiment, the Stützreibrolle for removal laterally, that is, in the direction of its longitudinal axis, are pulled out of the driver. This can be done before or after the removal of the driving roller according to the invention. [001] · ♦ • s * * * · · * * ♦ • «· ··. This can also be done while removing the drive roller from the driver; In this way, removal of the drive roller and the support drive roller can be carried out faster than if the two withdrawals take place successively. Then, the internal prior art method during removal of the capstan additionally comprises the steps of: - releasing fixation devices for fixing the support drive roller in the driver, - removing the support drive roller by pulling it sideways out of the driver.
    According to a preferred embodiment, the drive roller and the support drive roller are removed from the driver in pairs by removing a holding device in which a pair of drive roller and support drive roller are arranged.

    When using drivers as known from EP747147B1 or AT500689B1 drive roller and Stützreibrolle be individually removed by means of hall crane from the driver and replaced with a prepared in a workshop drive roller or Stützreibreibrolle. An exchange usually takes between 5 and 10 hours and is therefore only carried out in the course of a planned shutdown of the rolling mill. With the above-described driver of the prior art, replacement can be performed in 10 to 15 minutes. An exchange can therefore also be carried out during the operation of the rolling mill in a short rolling break or simultaneously with a work roll change. Accordingly, the surfaces of the capstan rollers and supporting capstans do not need to be polished in the driver as known from EP747147B1 or AT500689B1 drivers, but it is possible to polish without stalling the mill equipment and thus perform perfect surface quality outside the driver.

    Summary of the Invention Technical Problem
    It is the object of the present invention to provide apparatus and methods which, especially when using the above-described driver according to the prior art, allow for a more flexible and rapid change of drive rollers and supporting drive rollers compared with the prior art and their processing in the immediate vicinity of the driver ,
    Technical solution
    This task is solved by a
    Hot rolling mill, comprising sequentially arranged along a longitudinal axis of the hot rolling mill - several hot rolling stations, - at least one coiler station, - at least one coiler station, which is characterized in that next to the driver station and / or coiler station, preferably from the hot rolling stations towards coiling beyond the coiler on extension of the longitudinal axis of the hot rolling mill, 201113520 15 4 4 »I Μ · * · * · 4 4 4 · # * * · 4» 4 t ·· * · · · · · · 4 4 · 4 4 44 # · · · At least one driver roll storage station and at least one driver roll preparation station are present, and that at least one at least between the driver station and the driver roll preparation station and the driver roll storage station, possibly also the hot rolling stations, movable manipulator available is.
    Driver roller storage station
    Driver roll preparation station and manipulator are parts of a capstan change system.
    If several coiling stations are present, these parts are preferably arranged beyond the last coiling station in the direction of strip travel.
    If there are multiple driver stations and / or multiple driver roll storage stations and / or multiple driver roll preparation stations, the manipulator is movable between all of these driver stations and driver roll preparation stations and driver roll storage stations.
    That driver roll storage station and
    Driver roll preparation station next driver station and / or coiler station means that they are in the immediate vicinity at a distance up to 40 meters, preferably up to 30 meters, more preferably up to 20 meters, most preferably up to 10 meters, are arranged.
    This shortens transport routes and saves time.
    The longitudinal axis of the hot rolling mill in strip rolling direction - also called strip running direction - to understand, as in the direction of the hot rolling stations to the coiler station.
    By the term hot rolling stations are meant the parts of the hot rolling mill in which rolling is carried out to produce hot strip. 201113520 »· ·» * * * 16 • «t * · * · · * * ··« ··· * «« '• ff «ff I» · · · · ··
    The term driver station is to be understood as meaning a part of the hot rolling mill in which a driver drives the hot strip. If multiple drivers are present, the hot rolling mill includes multiple driver stations as shown in FIG.
    The term coiling station means a part of the hot rolling mill in which the hot strip is wound on a reel. If multiple reels are present, the hot rolling mill comprises several reel stations, as shown in FIG.
    A driver station is not part of a coiler station.
    With driver rollers while the roles are meant that are used in the driver station for driving, so driving rollers and Stützreibrollen.
    The term manipulator is understood to mean a device by means of which manipulated components of the hot rolling mill can be removed, for example, and / or insertion of driving rollers from or into the driver station, driver roller processing station, driver roller storage station, for example a crane or a robot.
    For example, in the driver roll preparation station, driver rolls are ground and / or polished, or driver rolls are assembled or disassembled. Such prepared driver rolls can subsequently be inserted into the driver roll storage station. The driver roll storage station may also contain unprecedented driver rolls that have never been used before.

To achieve maximum benefit in terms of transport paths, the parts of the drive roller changing system are arranged as close to the driver stations. To maximize transport path benefits, the driver roll storage station and
    Driver roll preparation station as close as possible to each other.
    It is therefore preferred if the driver roller storage station, driver roller processing station and manipulator are arranged in the rolling hall of the hot rolling mill.

    Drive rollers and / or support rollers in the first driver roller storage station and / or the first driver roller preparation station; e) removal of drive rollers and / or support drive rollers to be used in the first driver station from the first driver roller storage station and / or the first driver roller preparation station, or from a second driver roller storage station and / or one second driver roller processing station, by means of the first manipulator and / or a second manipulator, f) method of first and / or second manipulator holding the drive rollers and / or Stützreibrollen to the first driver station, g) inserting the after step f) at the first Driver station located drive rollers and / or Stützreibrollen in the first driver station by means of the first and / or second manipulator. 201113520 20 ** ·· k · · ··· «··« ·· «· * ·« * · «« 4 · ·· · * · · · · · · «« «·· * · · * «··· 4» ·· «ft · · ·« «·
    These steps can be done in alphabetical order of their name, or in a different order. For example, after removing driver rolls from a driver by means of a manipulator, driver rolls already held by this manipulator can be inserted into the driver before the removed driver rolls are moved from the manipulator to a driver roll storage station and / or driver roll preparation station and stored there. Accordingly, steps would be to remove driver drivers to be inserted into the driver from a driver roll storage station and / or
    Driver roll preparation station, take place before these driver roles are inserted into the driver.
    In principle, the method attempts to select the sequence of method steps in such a way that the transport paths are minimized.
    In one embodiment of the method according to the invention are in the first and / or second
    Driver roller processing station prepared drift rollers and / or support rollers removed by means of the first and / or second manipulator from the first or second driver roller processing station, then moved the removed drive rollers and / or Stützreibrollen holding first and / or second manipulator to the first and / or second driver roller storage station, and then the removed drive rollers and / or support rollers inserted by means of the first and / or second manipulator in the first and / or the second driver roller storage station. 201113520 «« · * * * * * * * ··· «Μ • · tll« ** * * * 21 * »« ft »99» «· * ····· ···« ·· II * · 9 ·· ··
    That is, preprocessed drive rollers and / or support drive rollers are stored in the driver roll storage station after conditioning before being reinserted into a driver.
    Of course, recycled drive rollers and / or Stützreibrollen after processing also directly - that is, without prior placement in the
    Drive roller storage station - used in a driver. This is already shown in the sequence of steps e) to g) in the above described methods.
    The method preferably takes place automatically. This automatically means that after the triggering of the procedure by an operator from the control panel of the hot rolling mill, the procedure runs without further interaction with the operator. The operator can be a human or a computer system.
    The triggering may be caused, for example, by the occurrence of one of the following cases: - Packing or surface damage to the driver rollers, as detected, for example, by a surface sensing detection device for detecting surface defects, - Driver roll breakage - Bearing or material breakout - Desire Use of a different type of driver roller, for example as a result of change of the desired product, such as with amended requirements on the strip surface; as an example the rolling of checker plates
    The process according to the invention can also be semiautomatic; that is, at least one further step is controlled by a human operator in addition to triggering the method, as compared to an automatic procedure; For example, the operation of a crane by operating one of the crane 201113520 22
    depending crane control done by a human operator.
    With the present invention, it is possible to use for the best quality results of the product without standstill of the rolling mill quickly optimally adapted to the product driver rollers in the driver. Thus, the wear of the driver rollers can be optimally controlled - for example, it is possible to resort in the production of Riffelblechen specially provided for this purpose driver roles, while used for other purposes driver roles are spared.
    In addition, a manipulator present according to the invention can also be used differently, for example for the maintenance or replacement of components of the rolling mill system installed in the effective range of the manipulator, for example wear plates of the inlet guides, surface inspection of the roller table rollers, the wear plates.
