The subject invention relates to a

A strip processing cassette comprising a strip processing apparatus for a rolling mill, and a method for removing the strip processing cassette from the strip processing apparatus

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 rockers are rigid with a torsion spring of a spring. 201113521 2 »* * * * · • t i- '

Connected frame, which forms an axis of rotation for the wings.

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 °. The following is the drive roller and the 201113521 3 • * • «t« < «* • · *« * · »« * ·· «** * * ♦ * ·· * * * *:;

Stützreibrolle when installed usually cleaned and polished or polished dog. By cleaning and grinding or polishing in the system there is 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, grinding 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 the 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.

In the prior art, drivers are known which overcomes the disadvantages of the prior art and which cause less time labor with less security risks in the change of the reel than conventional drivers and methods.

Such a driver for a steel strip coiler has at least one support roller supported 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 portion of the rocker is. 201113521 4 · · · «« «« «· · · · · · · · · · · · · · · · · · · · · · wobei wobei wobei wobei wobei wobei wobei 44 44 44 44 Storage area is open for insertion or removal of the drive roller to the side and / or up when the rocker position in the 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. 201113521

According to another embodiment, the fixing mechanism comprises a folding device whose parts are foldable about at least one axis attached to the rocker, and which are fixable to the rocker. 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. 201113521 6 * 1 * * «·, ♦ · · 4 4 * * * * * * * * t I t» · * t I 4 | J 4 »* ··· *» 4 * · * ♦ · * »I J i * ·

The holding device, which may be a holding frame, for example, thus contains both the drive roller and the support drive roller.

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. 201113521 7 * «

In the drivers shown in EP747147B1 or AT500689B1, one end of the rockers is pivotable about an axis of rotation, while the other end of the rockers is connected to an actuator such as a pressure medium cylinder, preferably a hydraulic cylinder. 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 bearing area of the drive roller can be located between the axis of rotation range and the actuation area, as in EP747147B1 or AT50Q689B1.

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 rocker 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. 201113521 8 • «

Another internal prior art is a method for removing a drive roller from a driver according to the internal state of the art.

This method is characterized in that it comprises the steps of - opening the fixing mechanism, - removing the drive roller to the side and / or up from the driver.

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. 201113521 9 * i * * * * * * * »* < * * * «I«: «* ·« * t * * 4 * a $ * »* *« · | «·« · * »* ·« | M · * - - f * + * * ft *

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 removing the drive roller according to the invention. 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.
