Definitions

• the invention relates to a reel device for a rolled strip, comprising at least one drivable trough roller for rotating a coil when winding or unwinding a rolled strip and with a roller table upstream or downstream of the reel.
• Coiler devices with trough rollers are usually used in the outlet section of a hot wide strip, or during hot strip transport.
• the purpose of the trough roller is to turn the coil with its drive and to advance the rolled strip using a pair of scissors that are arranged at right angles next to the coil transport. The coil is scooped on the scissors and samples are cut from the rolled strip.
• Trough rollers previously used in the prior art are designed with fixed diameters and for an approximate radius adjustment with a hollow contact surface for the coil. When turning spherical coils, this leads to markings on the coil circumference as a result of line contact rolling effects.
• the well-known versions of trough rollers are also very stiff due to their dimensions and do not allow the roller to bend.
• the document DE-OS 24 127 47 describes a stripping and straightening system for bundles of hot-rolled sheets with a pair of support rollers for the sheet bundles and a holding device for the sheet end, with which the sheet can be pulled off via a counter-bending roller.
• the two support rollers and a lifting table arranged between them are mounted on a movable coil carriage.
• the carriage is with one puller carriage that can be coupled relative to the stationary holding device.
• the puller wagon carries an additional drivable support roller, which forms a further pair of support rollers with the support rollers of the coil carriage closer to it.
• Document DE 197 45 653 A1 describes a decoiler for uncoiling a tape wound into a bundle, with a decoiler and a roller table downstream of the decoiler, the roller table having a base frame with a lower drive and straightening roller and an attachment frame with an upper drive roller with one has upper driving axis and an upper straightening roller.
• the attachment frame has a collar opener on its side facing the Abhaspei for opening the waistband, wherein the attachment frame can be moved towards the Abhaspei.
• the collar opener can be pivoted back and forth about a pivot axis between an operating position and a rest position.
• Document DE 198 03 091 A1 discloses an operating method for a belt transfer system with a winding station with a winding roller on the inlet and outlet sides and a winding station with a winding roller on the inlet and outlet sides, one belt in the winding station Bundle is wound up, or a bundle is placed on the wind-up rolls and the bundle is carried by the wind-up rolls during winding up or after being put on,
• the bundle is transferred to the unwinding station and after the transfer, the bundle is carried by the unwinding rollers during unwinding.
• the winding stations are moved towards each other, the take-up reel is raised.
• the coil transfer system provided in accordance with the operating method with a winding station and with a winding roller on the inlet and outlet sides and an unwinding station with a winding roller on the inlet and outlet sides is designed such that the winding stations can be moved towards one another and that the winding roller on the inlet side can be raised.
• Document DE-30 31 825 C2 describes a device for transferring pre-rolled hot metal strips wound into bundles from a winding station assigned to a roughing train to an unwinding station assigned to a finishing train.
• the transfer device consists of a vehicle which is movable transversely to the direction of movement of the belt on a track and which has an approximately vertical arm in the working position with a laterally projecting support surface for the collar.
• the arm is part of an upper part arranged on a base frame.
• the route is adjustable to enable the federal government to be picked up and set down.
• the track for the vehicle is installed in the rolling mill under the floor.
• the upper part of the vehicle consists of articulated levers and, when folded, can be moved under the unwinding station of the finishing mill.
• the invention has for its object to provide a new constructive solution for the design of the trough roller of a reel device, so that it can better adapt to a spherical coil and provides good support over the coil width, so that marking marks, especially at thin tapes can be safely avoided.
• the trough roller is designed with an elastically movable jacket ring.
• the working surface of the trough roller be formed with a row of adjoining jacket rings which surround a core of the trough roller with a difference in diameter by means of support bodies which are spring-loaded from the inside against the jacket rings in such a way that they support the The contact surface of the trough roller with the coil is subjected to uniform contact pressure over its entire longitudinal extent.
• a further embodiment of the reel device according to the invention with a trough roller provides that the support bodies are designed to be curved on their contact surfaces in adaptation to the inner circle of the casing rings.
• each support body is back-lined with a package of disc springs with a predeterminable prestressing force. It can be provided that the support bodies are clamped into the casing rings with prestressable spring force.
• the invention further provides that adjacent outer rings connect with an oblique chamfer to the adjacent outer rings, particularly in the case of outer rings with a difference in diameter.
• the running surfaces of the casing rings can be designed with a slight crowning, which, however, does not exceed the dimension of the difference in diameter.
• the reel device is further developed in that two trough rollers, which can be arranged at a predeterminable, axially parallel distance, cooperate with one another to form a trough-shaped recess between them for receiving the cylindrical load of the coil. At least one of these trough rollers is equipped with a rotary drive.
• the trough roller advantageously comprises a solid central shaft, on which a medium Ren ring for receiving spring-loaded support body and a jacket ring with an outer race for load absorption in the form of a coil.
• the trough roller of the reel device has a contact surface, in particular a concave one, which forms when it is rolled on a coil and which can be automatically adapted to the usually spherical circumference of the coil by means of the elastically resilient jacket rings.
• Figure 1 shows the section through the trough roller in a plane perpendicular to
• Figure 1a in front view two spaced-apart trough rollers with the load bearing of two coils of different sizes
• Figure 1b the trough roller in side view with indicated load action
• Figure 2 shows the trough roller in a partial view, and below the trough roller shown in partial section of a cutting plane parallel to the center line.
• the jacket rings 4 to compensate for a calculable or, based on experience, load-dependent deflection of the trough roller 1 against its center in the outer diameter.
• FIG. 1 shows on the one hand a coil 2 with a large diameter and, on the other hand, a coil 2 with a smaller diameter supported on two trough rollers 1, 1 ', which are fixedly mounted at the predetermined spacing of their axes.
• FIG. 1b shows a side view of a trough roller 1 with an even load distribution over its length in the longitudinal direction with individual load forces acting on the side rings 4 lying next to one another.
• FIG. 2 shows that with a small difference in diameter, adjoining jacket rings 4, each with an oblique chamfer, connect to the adjacent jacket ring 4.
• the treads are also designed with a slight crown 9, which, however, does not exceed the difference in diameter.
• FIG. 2 shows in the lower sectional view clearly the inner structure of the trough roller 1 according to the invention.
• the casing rings 4 of the trough roller 1 comprise a solid central shaft 5. This carries a central ring 11 for receiving spring-loaded support bodies 6 and an outer race 12 for the load bearing.
• the trough roller 1 With this type of trough roller 1 according to the invention, it is achieved in a surprisingly expedient and uncomplicated manner that the trough roller also adapts to a spherical coil and provides good support over the coil width and avoids that undesired markings can occur, particularly in the case of thin strips.
