To prevent the slit strips from traveling on top of each other, to prevent damage to the edges of the strips and to achieve a clean separation of the individual strips coiled into rings, the device is provided with at least one separately controllable driver for each slit strip.
Description
DEVICE FOR SEPARATING SLIT STRIP
BACKGROUND OF THE INVENTION
1. Field of the Invention The present invention relates to a device for separating especially rolled metal strip which is longitudinally slit into at least two strips, wherein the two strips are conveyed to a strip coiling device, for example, a coiling reel.
BACKGROUND OF THE INVENTION
1. Field of the Invention The present invention relates to a device for separating especially rolled metal strip which is longitudinally slit into at least two strips, wherein the two strips are conveyed to a strip coiling device, for example, a coiling reel.
2. Description of the Related Art Materials which have been rolled in roll stands into more or less thin or wide strips are longitudinally divided into narrower strips for further processing as necessary, wherein the narrower strips are coiled and are made available as narrow coils for shipment and for further processing. The wide strips are usually longitudinally divided in so-called strip cutting machines.
Longitudinally divided or longitudinally slit strip has the tendency to travel one on top of the other in subsequent plant units. Consequently, there is the danger of damage to the edges.
In addition, when the strips are coiled, a clean separation of ... CA 02363585 2001-11-19 the individual coils or rings must be carried out. Accordingly, it must be ensured that the produced narrow strips can be threaded without manual manipulations in the correct position and cleanly separated from each other into the reel slot of a coiling reel. Furthermore, a good strip guidance must be ensured in front of the separating device as well as following the separating device up to the reel in order to avoid damage to the edges.
Devices for separating longitudinally divided strip are known in the art. Using a so-called Diabolo roll, the strip halves are driven apart from each other by means of a convex roll. Driving the strip halves apart takes place in an unregulated and uncontrolled manner. Separating disks are known for mechanically separating the strip halves, however, these separating disks may cause damage to the edges. Also known in the art are devices for cutting out a middle strip which results in an undesirable loss of material.
German Patent Application 1 627 328 discloses a method for longitudinally dividing a rolled metal strip into at least two strips. In accordance with this method, the strip travels between the last stand of a hot rolling train and the subsequent reel through two pairs of drive rollers which are arranged at a distance from each other. The metal strip is longitudinally divided in the space between these two drive rollers after the beginning of the strip has entered the reel using slitting knives which can penetrate the strip. Alternatively the slitting knives could also be replaced by laser radiation. The scrap at the edges resulting from longitudinal cutting is discharged laterally, maybe comminuted or separately reeled.
DF 19S 44 237 A1 discloses a strip guiding system for a strip cutting machine with a circular knife shear as the cutting tool for longitudinally cutting especially relatively thick strip material. The strip guiding system includes an integrated clamping slot press-on device, a strip end holding device and a partial strip discharge device. Arranged following the circular knife shear is a strip decelerating device. Also provided is a separating device in order to guide the strip beginnings in the correct position from the bottom side. After the threading-in procedure of the strip into the reel slot and after hydraulically tensioning the strip beginnings, a hydraulically operated pressure roller is placed on the strips, so that the movably mounted transition at the reel slot can adjust to the respective strip thickness of the material to be coiled. The strip guiding system disclosed in this document is technically relatively cumbersome and cannot be universally used.

_ CA 02363585 2001-11-19 SUb~ARY OF THE INVENTION
Starting from the prior art discussed above, it is the primary object of the present invention to provide a device for a preferably regulated separation of slit metal strip in which the strips are prevented from traveling on top of each other, wherein damage to the edges is prevented, and wherein a clean separation of the individual strips coiled into rings is achieved.
Ir_ accordance with the present invention, the device for separating slit metal strip in a controlled manner is composed of at least one separately controllable driver provided for each slit strip.
The already slit metal strip is guided through the drivers.
The widths of the rollers of the drivers are selected in such a way that each partial strip can be separately controlled by a driver. If the strips are divided several times, a corresponding number of drivers is provided. Each driver is provided with a device for strip control.
In accordance with a further development of the invention, the driver configuration is placed on a sliding frame. In addition, the threading device (deflecting driver and threading table) is placed on the sliding frame. During the threading-in procedure of the slit strip, the device is moved back in accordance with the growing coil on the coiling reel against the strip travel direction at a constant distance from the outer diameter of the coil. This makes it possible to place the control device of the drivers always as closely as possible to the winding point. This counteracts the tendency of the divided strips to travel on top of each other again. This also facilitates the separate coiling procedures.
The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of the disclosure. For a better understanding of the invention, its operating advantages, specific objects attained by its use, reference should be had to the drawing and descriptive matter in which there are illustrated and described preferred embodiments of the invention.
BRIEF DESCRIPTION OF THE DRAWING
In the drawing:
Fig. 1 is a top view of a driver arrangement for slit metal strip according to the present invention; and Figs. 2a to 2d show a sequence of positions of the arrangement for coiling and controlling a metal strip which is divided in the middle.
DESCRIPTION OF T8E PREFERRED EMBODIbIENTS
Fig. 1 schematically shows in a top view the driver arrangement for divided middle strip 1, 1' which is conveyed with a defined distance 2 between the strip halves in the strip travel direction 3 to a coiling reel, not illustrated in detail.
Provided for each slit strip 1 or 1' is a driver 4, 4' with a currdsponding roller axis 5, 5' and drive roller bodies 6, 6'.
The drivers 4, 4' are arranged one behind the other as seen in the strip travel direction 3. Each driver 4, 4' is equipped with a device for strip control which is not illustrated in detail.
The width of the rollers of the drivers 4, 4' are selected in such a way that each slit strip 1, 1' is separately controlled by a driver 4, 4'.
Figs. 2a to 2d are elevational views showing different positions during coiling/controlling a metal strip which is divided in the middle. For example, the strip thickness BD is 0.4 to 3.0 mm and the strip width BB is 600 to 2,060 mm. The strip speed VmaX is about 600 m per minute. The threading-in speed into the reel is, for example, V~aX = 50 m per minute.
The Figures of the drawing show two drivers 4, 4' which are arranged on a sliding frame 7. Also arranged on the sliding frame 7 is a threading device 8 with deflecting driver and threading table. The sliding frame 7 is slidable with respect to its position by about 2,200 mm by means of, for example, a piston/cylinder unit 9. The coiling frame 10 is mounted stationary on the foundation 11 behind the sliding frame.
Fig. 2a shows the position P1 in which the coiling process for the split strip 1, 1~ is inspected. Fig. 2b shows the position P2 of the sliding frame 7 in which threading of the split strip 1, 1' into the reel slot takes place. Fig. 2c shows the position P3 of the sliding frame 7 in which coiling is finished. Fig. 2d shows the position P4 of the sliding frame at the start of the coiling process.
During the threading process, the entire device mounted on the sliding frame 7 is moved back in accordance with the growing coil on the coiling reel 10 against the strip travel direction 3 at a constant distance from the outer diameter of the coil. This makes it possible to have the control drive unit always placed as closely as possible to the coiling point. This makes it advantageously possible to prevent the divided strips 1, 1~ from traveling on top of each other again which, in turn, significantly facilitates the separate coiling process for each metal strip.
While specific embodiments of the invention have been shown and described in detail to illustrate the inventive principles, it will be understood that the invention may be embodied otherwise without departing from such principles.
