Description

Apparatus and method for winding a strip material

The invention relates to a device for winding a strip material into a coil having a rotor reel which comprises two rotor side parts which are rotatable about a common rotor axis and which are spaced apart in the axial direction of the rotor axis such that reel-driven reel mandrels can be supported between them.

The invention further relates to a method for winding a strip material into a coil having a rotor reel rotatable about a rotor axis, wherein for winding the coil, a first coiler mandrel is first pivoted by means of a first pivotable rocker part into a position axially adjacent to an Anwickelposition and then by means of a first Axialverlagerungseinrichtung is moved in the axial direction of the rotor axis in the Anwickelposition; wherein the coil is wound in the winding position on the first coiler mandrel supported between first and second rotor side portions of the rotor reel, and wherein the coiled coil is then rotated from the coiling position to a winding position of the rotor reel for finish winding by means of the rotor reel.

Generic devices and methods are known from the prior art. Typically, these are provided at the end of a hot or cold rolling mill or other strip-making machine, such as metal belts, to form these ribbon-like flat products into a coil by means of a coiler mandrel in a winding process winding up and thereby be able to provide compact for further processing.

To realize in particular such a device can serve different plant concepts. For example, such a device can be designed as a single-reel or to increase production as a stand-alone two-coiler system with a band switch. Or it's a carousel Coiler, which is often referred to as a rotor or reversing reel, provided in which a coiler mandrel for winding the strip material is in the optimal Anwickelposition, this is then transferred to the Anwickeln in a winding position, and thereby immediately another coiler mandrel in the Anwickelposition is moved in to be prepared for further wrapping a next coil. Consequently, the one-reel has the longest string follow-up time, since after the removal process of the coil first preparations must be made for winding a new coil. Significantly shorter follow-up times can be achieved in the two-reel systems with band switch and the carousel coiler, since these preparations can take place time-neutral.

In the known system concepts, the reel mandrels on one drive side of the respective device with one end are always fixed, so insoluble, integrated in their rotary drive devices whose bearings are designed so that the forces acting on the cantilever mandrels tremendous weight and labor reliably on the camps Rotary drive means or related gear bearing can be derived on the drive side in the frame of the respective device for winding. However, this design has the disadvantage that the required for winding full tape tension is often possible only after a repeated rotation of the retaining mandrel and an additional storage of the free end of the projecting coiler mandrel in a support bearing. In particular, up to this additional storage of this free end of this reel mandrel is loaded by very high moments. In view of the current trend towards ever wider belts to be wound up to over 2 m of bandwidth, the coiler mandrel and thus in particular its gearbox bearings are subjected to extremely high loads. In addition, there is the further trend towards the production of high-strength strip grades, which require extremely high strip tension for winding.

In addition to this drive side there is still an operating page, which is formulated by the respective free cantilevered end of the reel mandrels. From the operating side, the reel mandrels are operated. That means that of this Operating side ago, for example, by means of a sleeve handling system empty cores are pushed axially onto the reel mandrels. Or, starting from there, for example by means of a coil lift truck, ready-wound coils are drawn off axially from the reel mandrels and fed to a further transport device or clipboard device.

For example, from the publication CN 101 642 783 a generic device for winding a strip material with a carousel whip is known, which has a coiler mandrel drive with a but quite elaborately constructed transfer case unit to transmit the rotary drive power. This on the drive side of the complex and complex construction transfer case unit requires all the highest production engineering precision to manufacture the variety of precisely functioning gear meshes. In this respect, each transfer case unit is a complex special design. Thus, the coiler mandrel drive is very expensive to manufacture. In the case of repair or maintenance, the entire device is still, as no replacement or emergency operation is possible. Also, accessibility to maintenance is difficult due to the complexity of the transfer case assembly. Furthermore, the reel mandrel drive shown there is characterized by a relatively elongated structure starting from the drive motor of the coiler mandrel drive to the free reel mandrel ends, which can act especially on the gearbox bearings of the coiler mandrel drive high transmission bearing forces. Furthermore, the coiler mandrel drive with regard to its gear lubrication with a lot of lubrication points and with respect to a rotation of the carousel reel has a complex media supply and removal and also a complex supply of hydraulic oil through expensive and wear-susceptible rotary oil supply.

In addition, a generic device for winding a strip material with a turning reel known from the document DE 10 2006 038 493 A1, in which the reel mandrels consist of two reel semi-mandrel parts. This means that two axially opposite coiler semi-arbor parts together a single coiler mandrel for reeling a Form coils. Since the reel half-mandrel parts do not project so far out of the respective drive side, lower rewinding moments act on the reel half-mandrel parts and their reel mandrel drives. The respective coiler mandrel forming reel half mandrel parts are not connected to each other, whereby each reel half mandrel part has a separate drive. The separate and simultaneous drive from both sides, ie from the drive side on the one hand and the operating side on the other hand, often causes undesirable distortions within the wound coil. The short coiler half-mandrel parts are moved toward one another or away from one another by means of guide devices. As a result, the guide devices are subjected to extreme loads in the case of high coil masses and / or wider belts to be wound and / or higher belt pulls, as a result of which, in particular, these guide devices must be designed correspondingly solid. However, this is expensive and such leadership facilities come constructively thus to its limits. The invention has the object of further developing generic devices and methods for winding a strip material in order to overcome at least partially the aforementioned disadvantages.

The object of the invention is achieved by a device for winding a strip material into a coil having a rotor reel which comprises two rotor side parts which are rotatable about a common rotor axis and which are spaced apart in the axial direction of the rotor axis in such a way that rotationally driven reel mandrels can be held between them wherein the device comprises outside the rotor reel two independently swingable rocker parts which are pivotally mounted to the two rotor side parts, wherein each of the rocker parts comprises an axial displacement means by means of which the reel mandrel mounted on the respective rocker part is displaceable in the axial direction.

By the two outside of the rotor reel independently swingable rocker parts, which pivotally to the two rotor side parts are stored, a particularly advantageous handling of the reel mandrels is achieved, namely that a second coiler mandrel can be pivoted almost arbitrarily relative to the rotor reel, while a first coiler mandrel is within the rotor reel in use, more precisely while a band material is wound on the first coiler mandrel , In addition, the reel mandrels can be inserted into or withdrawn from the rotor reel, whereby the respective reel mandrel located outside the reel can be rotated between different positions, while the other reel mandrel is in a reel use. By means of the axial displacement device, the respective coiler mandrel can be displaced in a constructively simple manner relative to the associated oscillating part in the axial direction. As a result, the handling of the reel mandrels on the present device can be further automated and simplified.

For the purposes of the invention, the term "strip material" describes any ribbon-like flat products which are wound up into a coil, a bundle or the like in the course of their production process.These ribbon-like flat products may preferably be rolled strips of steel or non-ferrous metals.

In the present case, the term "coiler mandrel" describes a rotary component on which either the strip material to be wound is wound up directly or a sleeve element is previously pushed onto the coiler mandrel on which the strip material to be wound is then wound up while the coiler mandrel is rotated.

The reel mandrel is in this case formed in one piece and thus does not consist of two frontally held to each other Haspelhalbdornteilen, as is partially common in the prior art.

The term "rotor reel" is to be equated in the art with the terms "reversible reel" or "carousel reel". The terms "coil" and "collar" are used interchangeably for the purposes of the invention.

The term "winding" encompasses both winding the strip material into a coil on a coiler mandrel and unwinding the coil from such coiler mandrel Thus, the device according to the invention can wind the strip material into a coil not only on an exit side of, for example, a rolling mill or the like but also for unwinding a tape from a coil to an inlet side of a rolling mill, etc. In this respect, the present apparatus can be used and used in a variety of manufacturing plant locations and for a variety of purposes.

By means of the two oscillating parts which can be vibrated independently of one another outside the rotor reel, a transfer device which operates independently of a rotation of the rotor reel is presently provided, by means of which a coiler mandrel can be moved, for example, from a first working position into at least one further working position without rotation of the rotor reel.

For example, the first working position is a position to the side of a winding position of the present device, in which the coil is wound. The further working position may, for example, be a position laterally of a winding position in which the wound coil is finished wound.

The term "winding position" in the present case describes a position of the respective coiler mandrel within the rotor reel, in which a strip material wound on the reel mandrel is finish wound into the coil, in contrast to which the coiling position is to be mentioned, in which the strip material is wound only on the respective coiler mandrel ,

The present transfer device can be very well integrated into the present device, when the transfer device or its swing parts a Has pivot axis which coincides with the rotor axis of the rotor reel.

Furthermore, it is advantageous if the transfer device or its oscillating parts are rotatably mounted with the rotor reel. As a result, a coiler mandrel mounted in the transfer device can remain supported on the transfer device or on one of the swivel parts even during a rotation of the rotor reel.

Moreover, it is particularly advantageous if the two swinging parts are pivotable independently of the rotatable rotor side parts by at least 180 ° about the rotor axis of the rotor reel. As a result, a reel mandrel held on one of the swivel parts can be transferred, for example, from a winding position into a winding position without the rotor reel having to rotate for this purpose.

Advantageously, each of the swinging parts has its own swinging drive mechanism.

Furthermore, it is advantageous for a reliable operation when the two oscillating parts each comprise a holder with a preferably linear guide path which extends in the axial direction along the respective oscillating part, about one coiler mandrel outside of coiler mandrel holders of the two rotor side parts relative to the rotor coiler translationally movable to hold.

As already explained, it is advantageous if each of the swinging parts comprises an axial displacement device, by means of which the respective coiling mandrel is axially displaceable in the axial direction of the rotor axis in order to insert a drive journal of a coiler mandrel on the drive side into a receiving element of the driven holding means.

For example, by means of the Axialverlagerungseinrichtung at each swing part structurally simple a traversing mechanism for a coiler mandrel be realized, which moves the respective held by the swing member coiler mandrel axially in the direction of the rotor axis in its operating position in or out of this. For example, for relative translational displacement relative to a receiving element of the driven holding means. The axial displacement device can be designed differently. It is particularly advantageous if it has a guideway which extends, preferably linearly, in the axial direction along the respective oscillating part. The swinging part in this case provides a truss element along which the guideway extends. Preferably, the guideway opens into the rotor axis of the rotor reel.

Moreover, it is advantageous if the axial displacement device comprises a slide part, which can be moved translationally along the guide track.

A carriage part drive can be designed differently. Either this is housed within the respective swing part or in the slide part itself.

It is constructively advantageous if a spreading mechanism for radially spreading an outer surface area or for collapsing the previously spread outer surface area of the respective coiler mandrel is arranged immediately in the carriage part.

In any case, it is advantageous if the slide part is permanently connected to the coiler mandrel. Preferably, the carriage part is a functional component of the coiler mandrel.

Another important feature is the fact that a rocker part rotates together and synchronously with the rotor side parts of the rotor reel, when the reel mandrel associated with this rocker part is operatively connected in particular with its drive-side first end to the output element of the associated coiler mandrel drive. Is the coiler mandrel of the Output element disengaged and moved axially adjacent to the rotor reel, then this comprehensive coiler mandrel part can rotate independently of the two rotor side parts of the rotor reel to the rotor axis of the rotor reel. The object of the invention is also achieved by a method for winding a strip material to a coil with a rotatable about a rotor axis rotor reel, for winding the coil a first coiler mandrel first pivoted by means of a first pivotable rocker part in a position axially adjacent to an Anwickelposition and then is displaced by means of a first axial displacement in the axial direction of the rotor axis in the Anwickelposition; wherein the coil is wound in the winding position on the first coiler mandrel held between first and second rotor side portions of the rotor reel, the coiled coil being subsequently wound from the coiling position to a winding position of the rotor reel for finish winding by means of the rotor reel, and wherein the method characterized in particular in that the first oscillating part rotates outside the rotor reel; the first coiler mandrel is pivoted outside the rotor reel to the position axially adjacent to the coiling position by means of the first oscillating member; and the coiler mandrel is then displaced by means of the first axial displacement device relative to the first oscillating member in the axial direction of the rotor axis between the first and the second rotor side part such that a drive-side first end of the first coiler mandrel is operatively connected to and connected to an output element of a coiler mandrel drive arranged on the first rotor side part second end of the first coiler mandrel is supported on a second rotor side part.

By means of the method according to the invention, the winding process for winding the strip material into coils is significantly accelerated since individual process sequences can sometimes be carried out in parallel on the device. An advantageous first variant of the method provides that the first swing part, from which the first coiler mandrel has been moved axially into the Anwickelposition synchronously rotates in the same direction with the rotor reel about the rotor axis when the first coiler mandrel is rotated from the Anwickelposition in the winding position. As a result, the first coiler mandrel can remain in operative contact with the first oscillating part, as a result of which the present method can be further simplified.

Moreover, it is advantageous if, after the finished winding, the first coiler mandrel is pulled axially out of the finished wound coil and parked laterally outside the rotor reel on the first oscillating part turned into the winding position. As a result, the coil can be released in a particularly simple manner for further transport from the winding position.

If the strip material is cut off after the finish-winding and the coil is transported away in line from the rotor reel after the finish-winding, the method can be further simplified.

An Anwickelvorgang another coil can already be prepared by the device when a second reel mandrel mounted outside of the rotor reel is placed by means of a second rotor part arranged outside the rotor reel in a position axially adjacent to the Anwickelposition, during or after the first coiler mandrel with the coiled coil means of the rotor reel is rotated from the Anwickelposition into the winding position or was.

If the second swing member is rotated with the second coiler mandrel from a position axially adjacent to the winding position to the position axially adjacent to the Anwickelposition while the first oscillating member is rotated in the opposite direction to the winding position, the winding process can be further streamlined.

A further process optimization can be achieved if the second coiler mandrel by means of a second axial displacement device relative to the second oscillating member in the axial direction of the rotor axis is shifted from outside the rotor reel to the Anwickelposition between the first and the second rotor side part, while or after the coil is wound on the first coiler mandrel or was finished, wherein a drive-side first end of the second coiler mandrel with a on the second rotor side part disposed output element of another coiler mandrel drive operatively connected and a second end of the second coiler mandrel is supported on the first rotor side part.

A high throughput can be achieved when a new coil is wound by repeating the method steps explained hereinbefore, wherein the second devices, in particular the second coiler mandrel, take the place of the first devices and vice versa.

With the present invention, a highly productive rotor reel constructive very simple construction and the coiler mandrels are arranged completely removable on this.

Advantageously, on each of the rotor side parts both driven by a coiler mandrel drive holding means and non-driven, so not driven by the coiler mandrel holding means arranged whereby the rotor reel constructively very simple and the reel mandrels can be arranged completely removable on this. This results in a completely new plant concept.

In particular, this eliminates the previous distinction between a drive side and an operating side of the device for winding the strip material to a coil, whereby in particular the rotor reel can be built symmetrically. As a result, occurring forces and moments can be controlled and recorded much better within the device for winding the strip material. In this respect, on the one hand, wider tapes to be wound and / or higher tape pulls can be realized with the device according to the invention. Furthermore, the reel mandrels are from the beginning, so already when Anwickeln a new coil at both ends, ie drive side as well as support or storage side, mounted in accordance with trained coiler mandrel holders on the rotor side parts and thus supported. Thus, the fastest possible construction of a sufficiently high strip tension is guaranteed, on the one hand to wind stable eyes (inner turns) and, on the other hand, high-strength strip materials with high strip tension.

In this context, it is advantageous if the rotor reel has a Anwickelposition for wrapping the metal strip on the coiler mandrel, in which the coiler mandrel is supported on both sides in two opposite coiler mandrel holders of the two rotor side parts.

In addition, good accessibility to the individual components or groups of components is given, whereby about a simplified maintenance and repair if necessary can be achieved. Furthermore, the potential for larger bandwidths preferably increases in conjunction with smaller reel mandrel diameters.

The present device is characterized in particular by the extraordinary feature that the reel mandrels are mounted so removable on the rotor side parts, that these reel mandrels for operating the device of both rotor side parts can be completely dissolved and removed. The operation of the device comprises for example a Andienen of sleeves, on which the tape material can be wound after a corresponding sleeve has been pushed onto the coiler mandrel. Or it includes about a withdrawal of a wound coil from a coiler mandrel.

The present device is, for example, in an outlet of a rolling mill, in which the coil handling, so the removal of a finished wound coils, can be done in a rolling line, and in which the coils on a continuous reel mandrel wound with or without sleeve and ready to be wound. That is, the coil requires only a reduction to a simple transport device, for example in the form of a chain element.

Both the driven and the non-driven holding means are components of arranged on the rotor side parts coiler mandrel holders for fixing the respective retaining pin.

The term "driven holding means" in the context of the present invention describes a reel mandrel holder on the rotor side part, which comprise an output element of a drive train of a coiler mandrel drive and by means of which a correspondingly shaped, driven end of a retaining mandrel is supported by the coiler mandrel drive on the rotor side part.

Accordingly, the term "non-driven holding means" in the present invention describes a further coiler mandrel holder on the same rotor side part, by means of which a correspondingly shaped further, non-driven end of another retaining mandrel is mounted on this rotor side part, bypassing an interaction with the coiler mandrel drive drive-less holding means are not driven in such a way that they could set one of the reel mandrels in rotation, but instead only support the further end of the respective reel mandrel or only support it and only move around with the connected reel mandrel.

In contrast to the previously known solutions, it is advantageous if the reel mandrels are mounted releasably on the two rotor side parts in reel mandrel holders such that these reel mandrels are completely removable for operating the device from both rotor side parts. The operation includes, for example, a Andienen of pushed onto the coiler mandrel sleeves on which the tape material can be wound. Or it includes about a withdrawal of a wound coil from a coiler mandrel. A further advantageous embodiment provides that the two rotor side parts are arranged rotated by 180 ° about the rotor axis to each other such that the driven holding means of the first rotor side part and the non-driven holding means of the second rotor side part and the non-driven holding means of the first rotor side part and the driven holding means of second rotor side part are arranged opposite one another. As a result, the present rotor reel can be provided in a structurally particularly symmetrical manner.

If the two rotor side parts are configured identically, at least with regard to their essential functional components, the number of different components or component groups can advantageously be further reduced. As a result, a reduction in spare parts stocking can also be achieved. The identity here essentially relates to the essential functional components or functional areas of the rotor side parts. The stability in particular of the rotor reel can be further improved if the holding means of the two rotor side parts of the rotor reel are arranged in the axial direction of the rotor axis stationary relative to one another. But this does not have to be compulsory.

The rotor reel can be further simplified in construction if the driven holding means and the non-driven holding means of each of the two rotor side parts are arranged radially spaced from the rotor axis on different sides of the rotor axis.

A particularly quick attachment and detachment of the reel mandrels on or from both rotor side parts succeeds when the retaining means arranged on both rotor side parts and the reel mandrels supported on them are connected to one another in a releasable manner by releasable coupling devices, but are detachably connected to one another. It is understood that such coupling devices can be of various shapes. Below are some examples of how this related fast coupling holding means could be realized.

The coiler mandrels can be quickly coupled on the drive side with an output element of the drive train or decoupled from this output element when the driven holding means comprise a receiving element by means of which a drive journal part of the coiler mandrel positively and / or frictionally with the driveline of the coiler mandrel drive firmly but detachably coupled. Optionally, the retaining mandrels can also be clamped by means of expanding discs.

The coiler mandrels can be reliably fixed to the output element when the driven holding means comprise a clamping unit on the rotor side parts, by means of which a drive journal part of the coiler mandrel is firmly, but releasably clamped. A drive pin opposite the free end of the coiler mandrel can be set reliably on the non-driven holding means when the non-drive holding means comprise a further clamping unit on the rotor side parts, by means of which a drive pin opposite bearing point of the coiler mandrel is fixed, but releasably clamped. The device can be structurally further simplified if the two rotor side parts have a common drive device.

In addition, the present device is characterized by a reel mandrel holder for holding or storing the free end of the respective coiler mandrel. However, the drive-free holding means support the coiler mandrel already in its Anwickelposition on its non-driven coiler mandrel side and thus meet not only during reeling, but already when Anwickeln under train the function of an abutment. A corresponding In the present case, reel mandrel holder serves for the connection between the actual round coiler mandrel and its guide on a swinging part, which advantageously removably fixes on the non-driving holding means on the rotor side parts and the point of application for the movement mechanism. In addition, it guides and locks the coiler mandrel in the operating position.

Furthermore, the function of the device can be further improved if the device comprises a sleeve handling system. The sleeve handling serves to lend new sleeves to that of the two coiler mandrels, which will next pivot to the coiling position. Once a coil has been wound and the coiler mandrel has been withdrawn from the eye of the coil, a new sleeve is waiting in an intermediate position or in a parking position. The withdrawn coiler mandrel pivots by means of the swinging part in this intermediate position and the sleeve is pushed onto the coiler mandrel (transfer position). Thereafter, the sleeve pivots with the coiler mandrel in the Anwickelposition. Since one coiler mandrel pivots on the "drive side" and the other on the "operating side" on the rocker, the sleeve handling system has at least one parking position, for example in rolling line, and at least two transfer positions, namely on the respective coiler mandrel. The sleeve handling system can be structurally essentially very easily supplemented by a traversing device with a solid half-shell for receiving the sleeves. Instead of the half-shell, other components, such as a pair of pliers or the like, can be used. When using different types of sleeves with different diameters, the recording can also be positioned vertically. The same function is required if a different transfer level is required to load the sleeve handling due to the layout of the system. Such a sleeve handling system is already well known and will therefore not be discussed separately here.

In this context, it is advantageous if the coiler mandrel is axially pulled out of the finished wound coil and laterally parked outside the rotor reel, wherein the finished wound coil in line of the Rotor reel is removed. When parking in a corresponding intermediate position, for example, the sleeve handling system described above can be used well.

From further features to be emphasized, which advantageously further develop generic devices for winding strip material, a large number of additional advantages results.

In this context, in particular the advantageous symmetrical design of the device is to be mentioned, which allows the use of a solid or continuous and thus extremely stable coiler mandrel, which is already already supported when winding the coil always on both rotor side parts. This means that the Anwickeln already from the approximately third turn, especially when the belt winder is retracted, can be done under full tension. This is a significant advantage compared to conventional reversible reels in which the full strip tension can be built only when the reel mandrel is counteracted with its cantilevered end on the operating side in an additional support bearing, so only after the rotation of the rotor reel in the winding position.

In addition, the actual rotary drive of the coiler mandrel is always on the opposite side of the easy storage of the coiler mandrel. This means that the expansion side, on which the spreading mechanism or the non-driven holding means are located, and the drive side, on which the driven holding means are located, are always placed opposite to a reel mandrel. As a result, a more compact construction, in particular of the coiler mandrel, can be achieved. Furthermore, the coiler mandrel has, especially on the drive side, a coupling device in order to be able to quickly engage the driven holding means of the corresponding coiler mandrel holder, for example in the form of a flat journal or a star-shaped drive journal. In this respect, the rotor side parts have such a coupling device to the quickly fix the inserted coiler mandrel, transfer the drive power safely and, if necessary, be able to release it again.

By decoupling the full 360 ° rotation of the rotor reel from the 180 ° pivoting of the swinging part advantageously eliminates the need to install expensive and maintenance-prone rotary oil supply.

Furthermore, it is possible by the rapidly releasable active connections between the holding means on the reel mandrel holders, so by the releasable drive connections on the one hand and the opposite releasable free storage of the coiler mandrel on the other hand, and the reel mandrels to generate a previously unknown potential with respect to a coiler mandrel quick change.

In particular, a quick change of reel mandrels after accidents, after a change of coiler mandrel diameters or after installation of special mandrels, for example with rubber coating, can be achieved with the present device. Moreover, it is advantageous if the device comprises a winding stopper for avoiding telescoping inner turns when pulling the coiler mandrel out of an eye of a coil. He can constructively already based on known designs.

Furthermore, the device preferably comprises a known pressure roller, which can serve to press a strip of material end to the coil surface when winding the last turns. This prevents the free end of the strip from turning over, especially when the strip tension required for winding is removed.

Also, the device may be equipped with a belt winder known per se. The belt winder helps to wrap the beginning of the strip material in the winding position. It has preferably moved into the operating position when the strip material has moved to the winding position. He supports and guides the strip material with the help of guides and guide tables. In an Anwickelvorgang the coiler mandrel rotates - possibly with a mounted and clamped sleeve - at the same speed as the belt of the belt winder runs, and thereby helps to fix the first turns of the strip material around the coiler mandrel or around the sleeve. After about three turns, the belt winder is removed from the coiler mandrel and the actual reeling process under belt tension sets in.

In addition, the device may still be equipped with a coil or coil handling system. The transport of the finished coils is done in line. That is, the coil requires only by a suitable lowering a lowering to a simple-built transport device, for example in the form of a chain or the like. This can be dispensed with an expensive coil handling via coil pallet truck.

With the present device, a variety of advantages can be achieved, namely, for example, faster coil follow-up times than in a conventional device with a conventional carousel reel the case, whereby a total plant utilization and thus an associated increase in production can be achieved. In addition, the present device is characterized by the use of simple components; that is, in particular, a simplification of the installed components, component and / or component groups is achieved, whereby the maintenance intensity, downtime and investment costs can be significantly reduced. In addition, the fastest possible tensile structure and, as a result, a stable coil eye or collar eye can be achieved, whereby the risk of a collapse of the coil or collar eye in subsequent processes, for example in bell annealing, can be reduced. It is particularly advantageous that by means of the present device, with an appropriate design, an expansion of the system potential in general and in the direction of larger strip widths, higher strip tension, smaller reel mandrel diameter, use of product-specific reel mandrels, significantly shortened reel mandrel changing times during production or the like can be achieved , In addition, the present device is characterized by the fact that it is easier to maintain than a conventional carousel reel. In addition, characterized by a substantially symmetrical arrangement, which means using at least substantially the same components on both sides of the rotor reel, whereby a reduction in spare parts inventory is achieved. It is particularly advantageous that the present device has an extremely simple gear design. In addition, a very simple sleeve task is created. By the present device, a particularly simple tape sample removal in Conti operation is possible, even for an inline inspection. Moreover, a transmission of higher drive torques is possible, which is particularly advantageous for high-strength future used strip materials or for jumbo coils or the like.

With the device described here, in particular, the disadvantage can be overcome that the design of the coiler mandrel, its drive-side gearbox bearings and thus the design of the entire rotor reel is technically exhausted.

Further features, effects and advantages of the present invention will be explained with reference to the appended drawing and the following description, in which an exemplary device according to the invention for winding a strip material into a coil and a first possible method sequence is shown and described.

FIGS. 1 to 14 show and describe, by way of example, a first exemplary embodiment of the present inventive device 1 for winding a strip material 2 into a coil 3 and its modes of operation, the design of the device 1 essentially being shown in FIGS related to first Functional relationships is explained. Subsequently, according to the representations according to FIGS. 3 to 14, a possible method sequence is again explained concretely.

The device 1 shown in FIGS. 1 to 14 for winding a strip material 2 into a coil 3 has a rotor reel 4, which comprises two rotor side parts 6 and 7 which are rotatable about a common rotor axis 5.

The rotor reel 4 is rotatably mounted in a frame 1A of the device 1, wherein the device 1 is fixed by means of the frame 1A to a foundation, not shown here. The two rotor side parts 6 and 7 are so axially spaced apart in the axial direction 8 of the rotor axis 5, that between them rotationally driven reel mandrels 9A and 9B can be supported.

According to the illustration according to FIG. 1, the right, ie the second coiler mandrel 9B is already mounted on the two rotor side parts 6 and 7 of the rotor reel 4, namely within the rotor reel 4 between the two rotor side parts 6 and 7. The example in FIGS. 1 and 2 between the two rotor side parts 6 and 7 shown rotationally driven second coiler mandrel 9B rotates at a arrival or even at a finish winding of the coil 3 about its axis of rotation 10. The left, so the first coiler mandrel 9B is still placed outside the rotor reel 4, namely left axially in addition to the first rotor side part 6.

The rotor side parts 6 and 7 of the rotor reel 4 can in this case be rotated at least in such a way by 360 ° that the reel mandrels 9A and 9B respectively mounted within the rotor reel 4 either in a Anwickelposition 1 1 (upper position) or in a winding position 12 (lower position) can be positioned.

A particularly simple construction of the rotor reel 4 results solely from the fact that the rotor side parts 6 and 7 at least in terms of their essential functional components are identical. In this respect, explained features and / or functions, which are exemplarily shown and / or explained only on one of the two rotor side parts 6 and 7, always apply to both rotor side parts 6 and 7. To the reel mandrels 9A and 9B at both ends 15 and 16 at the latest already at a Anwickelvorgang in the Anwickelposition 1 1 in the rotor reel 4 to support and store, the two rotor side parts 6 and 7 have a special construction, namely each of Rotor side parts 6 and 7 on the one hand driven holding means 17 for driving a drive-side first end 15 of a coiler mandrel 9A and 9B and on the other hand driveless holding means 18 for merely supporting a further end 16 of another coiler mandrel 9A and 9B, wherein the driven holding means 17 in contrast are in each case operatively connected to the drive-free holding means 18 with a drive train 17A or 17B of a coiler mandrel drive 17C or 17D (see in particular FIG. 2).

As can be clearly seen in Figure 2, the device 1 thus has two reel mandrel drives 17C and 17D; for each drive train 17A and 17B and therefore for each rotor side part 6 and 7, respectively, a separate coiler mandrel drive 17C and 17D. By means of the two different types of holding means 17 and 18, the reel mandrels 9A and 9B can each be interchangeably mounted on the two rotor side parts 6, 7 in such a way that these reel spindles 9A and 9B for operating the device 1 are completely detached from both rotor side parts 6 and 7 can be solved. Due to the fact that the two rotor side parts 6 and 7 are identical at least with regard to their essential functional components and thus the respective coiler mandrel 9A and 9B with its drive-side first end 15 with the driven holding means 17 on the one hand and with its second end 16 with the non-driven holding means 18 on the other hand be operatively connected can, the two rotor side parts 6 and 7 are arranged rotated by 180 ° about the rotor axis 5 to each other such. This ensures that the driven holding means 17 of the first rotor side part 6 and the non-driven holding means 18 of the second rotor side part 7 in the sense of a first pair of holding means and the non-driven holding means 18 of the first rotor side part 6 and the driven holding means 17 of the second rotor side part 7 in the sense of a second pair of holding means always arranged opposite each other.

In this respect, the driven holding means 17 and the non-driven holding means 18 of each of the two rotor side parts 6, 7 in the radial direction 19 radially spaced from the rotor axis 5 relative to this rotor axis 5 on different sides 20 and 21 of the rotor axis 5 of the rotor reel 4 are arranged.

Thus eliminates the previously customary division between a pure drive side, from which the reel mandrels 9A and 9B are rotationally driven, and a pure operating side, from which the reel mandrels 9A and 9B are operated, ie from which finished wound coils 3 of the reel mandrels 9A and 9B withdrawn and, where appropriate, new cores can be pushed onto the reel mandrels 9A and 9B.

So that the individual reel mandrels 9A and 9B can be fixed or detached from the rotor side parts 6 and 7 quickly, the latter have quick release coupling devices (not explicitly numbered). These coupling devices are provided in a structurally reliable manner, in particular by features of the retaining means 17 and 18 which are mentioned below by way of example only. For example, the driven holding means 17 comprise a receiving element 25, by means of which a drive pin part (not shown) of the respective coiler mandrel 9 positively and / or frictionally coupled to the drive train of the coiler mandrel drive. Reliably, the reel mandrels 9A and 9B temporarily fixed to the driven holding means 17, since in this embodiment, the driven holding means 17 also have a clamping unit (not shown here) for clamping the drive pin. However, such a clamping unit can also be a functional component of the coiler mandrel 9A or 9B.

In order to be able to set the reel mandrels 9A and 9B reliably to the non-driven holding means 18 reliably, these drive-free holding means 18 have a further clamping unit, so that a bearing point opposite the drive journal can also be clamped. Since the respective drive train 17A or 17B of the respective coiler mandrel drive 17C or 17D is arranged at least partially within the rotor side parts 6 and 7 and configured there, the rotor side parts 6 and 7 are each configured as a rectangular gearbox part 27 (numbered only as an example) which in particular the driven by the coiler mandrel drive means 17 are arranged.

But not only the holding means 17 and 18 are arranged on this gearbox part 27, but also an outer ring gear 28 of a rotor drive 29 for the rotor reel 4 is fixedly connected to the gearbox part 27 and the respective rotor side parts 6 and 7. In the present case, the rotor drive 29 is a component of a common drive device 30 of the two rotor side parts 6 and 7.

This drive device 30 has a transfer case with two distributor shafts, each of which meshes with a pinion ring element via a pinion connection, each of the pinion ring elements respectively interacting with an external ring gear 28 fixed to the rotor side parts 6 and 7 in such a way that the rotor reel 4 moves through the rotor drive 29 the rotor axis 5 can be rotated. In particular, excess lubricant for the lying within the gearbox housing parts 27 of the rotor side part 6 and 7 and rotating gear components (not shown) of the respective drive train 17A and 17B of the respective coiler mandrel drive 17C and 17D constructively easy to remove again are on the rotor reel. 4 only two Drehölabführeinrichtungen 38 are provided, which are in this embodiment advantageously only with four Ölabführleitungen 39 (only exemplified) fluidly with the gearbox parts 27 in operative connection. Corresponding rotary oil supply devices are arranged centrally in the region of the common rotor axis 5, although they are not shown here.

Furthermore, the apparatus 1 comprises, as an essential functional component, a transfer device 40, by means of which a coiler mandrel 9A or 9B can additionally be displaced independently of a rotation of the rotor reel 4, although the transfer device 40 is also mounted to rotate with the rotor reel 4. As a result, the achievable with the device 1 effectiveness increases significantly.

The transfer device 40 comprises two rocker parts 43 and 44, which rotates in this embodiment about a pivot axis 41, which is equal to the rotor axis 5, so that the device 1, despite the transfer device 40 functionally very compact builds.

By means of the two rocker parts 43 and 44, the respective coiler mandrel 9A or 9B can be reliably carried by the transfer device 40, transferred to the rotor reel 4 in the axial direction 8 or mounted or taken over or removed from the rotor reel. Each of the rocker parts 43 and 44 pivots about the pivot axis 41.

A first rocker part 43 is arranged axially to the left of the rotor reel 4 and thus represents the left rocker part 43 of the device 1. Accordingly, a second rocker part is arranged axially to the right of the rotor reel 4 and thus represents the right rocker part 44 of the device 1.

The left rocker part 43 is in this case pivotally driven by a left rocker drive device 45 (see FIG. 2). The right swing member 44 is independently pivotally driven by a right swing drive mechanism 46 (see FIG. 2) thereof.

Both rocker parts 43 and 44 each comprise an axial displacement device 47 (numbered only by way of example) with a guide track 48 and a slide part 49 which can be moved translationally therefrom.

The slide part 49 comprises the respective coiler mandrel 9A or 9B, so that the respective coiler mandrel 9A or 9B can be displaced in the axial direction 8 of the rotor axis 5, wherein each coiler mandrel 9A or 9B is fixedly connected to its associated slide part 49. In this respect, each reel mandrel 9A or 9B always remains, that is, in particular in each method step, firmly connected to the associated rocker part 43 or 44.

It is understood that the interaction between the guideway 48 and the slide member 49 can be structurally different. In this embodiment, a not shown here Schlitteenteilverfahrantrieb is disposed within the carriage housing 50.

In the carriage housing 50, a spreading mechanism 51 for radially spreading an outer surface area or for collapsing the previously spread outer surface area of the respective coiler mandrel 9A or 9B is accommodated structurally compact. The respective rocker part 43 or 44 is pivotably mounted in a rocker part mount 52 (see also FIG. 2) about the rotor axis 5 or around the pivot axis 41 identical thereto. By means of the device 1 shown in Figures 1 and 2, the following exemplified first modes of operation are now possible.

According to the illustration according to FIG. 1, the second coiler mandrel 9B is already in the winding position 11 and the coil 3 has already been wound thereon. Previously, the right swing member 44 was pivoted upward so that the second coiler mandrel 9B is placed axially to the right of the coiling position 11. Subsequently, this second coiler mandrel 9B was inserted by means of the axial displacement device 47 in the axial direction 8 in the rotor reel 4 and operatively connected to the two rotor side parts 6 and 7. For this purpose, the carriage part 49 has been moved by means of its carriage travel drive along the guideway 48 in the direction of the rotor reel 4. In this case, the drive-side first end 15 of the second coiler mandrel 9B was introduced into the receiving element 25 of the driven holding means 17 of one of the holding mandrel holders in the winding position 11 and thus fixed there to the first rotor side part 6 by means of the corresponding clamping unit. The non-driven second end 16 of the second coiler mandrel 9B, that is, the end having a spreading mechanism 51 for radially spreading or collapsing the previously spread outer surface portion of the second coiler mandrel 9B, is fixed to the second rotor side member 7.

For winding the coil 3, a motor of the first coiler mandrel drive 17C (see FIG. 2) drives the receiving element 25 and thus also the second coiling mandrel 9B held in the coiling position 11 of the first rotor side part 6. After withdrawal of a belt winder not shown from the Anwickelposition 1 1 and / or after about three turns of the strip material 2, the applied to the strip material 2 reel draw is increased to a calculated required strength. After a few turns (or after release by the belt winder), the full repositioning of the belt takes place wound coils 3 in the winding position 12 by the rotor reel 4 rotates 180 ° about the rotor axis 5. Now the second coiler mandrel 9B previously shown in the Anwickelposition 1 1 is in the winding position 12; similar to that shown in FIG. 2 with respect to the first coiler mandrel 9A. In this case, ie during the rotation of the rotor reel 4, the strip material 2 continues to be wound up with full strip tension.

That is, the second coiler mandrel 9B, the right swing member 44, and the two rotor side members 6 and 7 rotate synchronously about the rotor axis 5.

The second coiler mandrel 9B with the now continuously increasing coil diameter would now be in the winding position 12 (not shown, but see FIG. 2).

By contrast, the first coiler mandrel 9A is supported by the left swinging part 43 as shown in FIG. 1 and is still in a waiting position axially to the left of the rotor reel 4. This arranged on the left swing member 43 first coiler mandrel 9A is placed from the waiting position later axially to the left of the Anwickelposition 1 1. Subsequently, this first coiler mandrel 9A can be pushed into the winding line 11 by the axial displacement device 47 in a further step (similar to that already described with respect to the second coiler mandrel 9B) and connected to the driven holding means 17 of the second rotor side part 7. Here, the non-driven end of the first coiler mandrel 9A is supported supported in the non-driven, non-driven holding means 18 on the first rotor side part 6.

In the winding position 11, the first coiler mandrel 9A waits for the start of the next coiling operation, while the coil 3 is finished wound in the winding position 12 (not shown, but see FIG. 2). The band end of the coil 3 is pressed with the assistance of a pressure roller 60 on the finished wound coil 3 to prevent cracking of the coil 3.

If the coil 3 located in the winding position 12 is completely wound, the first or second coiler mandrel 9A or 9B collapses by means of the spreading mechanism 51 and the first or second coiler mandrel 9A or 9B then axially out of the eye of the coil 3 from the rolling line pulled out to the right. At the end of the process, this first coiler mandrel 9A sits again completely on its left swing part 43 and the second coiler mandrel 9B again completely on its right swing part 44 and is ready to be pivoted again next to the Anwickelposition 1 1.

While in the above-exemplified first mode of operation was dispensed with a sleeve handling system, however, the device 1 may also be equipped with a sleeve handling system, not shown here, whereby the following example illustrated operation can be realized.

If the strip material 2 is wound onto the coil 3, for example, on a sleeve (not shown here), a position for a corresponding sleeve handling must be taken into account when pivoting one of the swinging parts 43 or 44 in the form of further intermediate positions or the waiting position. For this purpose, the reel mandrel 9A or 9B, after it has been pulled out of the eye of the wound coil 3 at the end of a winding process by means of the associated axial displacement device 47, pivots into the waiting position by means of the rocker part 43 or 44. Preferably in rolling line an empty sleeve is already waiting for a takeover by the respective coiler mandrel 9A or 9B. The sleeve is pushed by the sleeve handling system onto the reel mandrel 9A or 9B. This is advantageously already then, while a new coil 3 is wound in the Anwickelposition 1 1. After the sleeve has been fixed on the reel mandrel 9A or 9B, the corresponding swing member pivots 43 or 44 with the coiler mandrel 9A or 9B and the sleeve pushed thereon in the Anwickelposition 1 1, to then be inserted for an Anrolleln in the rolling line and in the Axialverlagerung 47 opposite reel mandrel holder of the corresponding rotor side part 6 or 7. Thereafter, a new Anwickeln done.

According to the illustration according to FIG. 2, the device 1 is shown by way of example in a further working phase in which the first coiler mandrel 9A is pulled out axially out of the eye of the finished coil 3, while the second coiler mandrel 9B is already in the coiling position 1 1 is located. In this case, the right swinging part 44 is pivoted upward with its guide track 48 and the left swinging part 43 pivoted with its guide track 48 downwards.

Quite essential to the present invention is that the two rocker parts 43 and 44 are arranged on opposite end sides outside the rotor reel 4, so that these, no matter what position they are, do not influence a winding phase within the rotor reel 4.

In addition to the possible modes of operation already described above by way of example, a possible method sequence is described in concrete terms using the following FIGS. 3 to 14 in order to convey the interaction of the individual device components even more clearly.

According to the illustration according to FIG. 3, a work situation is shown as an introduction to a possible method sequence on the device 1 shown in FIGS. 1 and 2, in which the first coiler mandrel 9A with the left oscillating part 43 outside the rotor reel 4, for example, axially into an upper position is pivoted to the left of the first rotor side part 6 and the Anwickelposition 1 1 in the direction of arrow 61. This work situation corresponds to the start of the plant with a first volume, if immediately before no band is in the continuous process. Further following bands are then processed continuously. The second coiler mandrel 9B is at the start of the The second reel mandrel 9B is already pulled out of the finished wound coil 3, which in line from the winding position 12th is removed. In the continuous process, the first and the second rotor side part 6, 7 oscillate in common or parallel.

According to the illustration according to FIG. 4, the left swing part 43 is pivoted into the upper position, so that the first coiler mandrel 9A is located directly axially to the left of the coiling position 11. As can readily be seen, the first coiler mandrel 9A is displaced in the axial direction 8 into the winding position 11 by means of the axial displacement device 47 of the left rocker part 43 until the first coiler mandrel 9A is located between the two rotor side parts 6 and 7 (see FIG. , The second coiler mandrel 9B is still unchanged with its right swing part 44 in the lower position to the right of the winding position.

According to the illustration according to FIG. 5, the first coiler mandrel 9A is operatively connected with its drive-side end 15 to the driven holding means 17 of the second rotor side part 7. On the first coiler mandrel 9A already the first coiler mandrel 9A supplied end of the strip material 2 is wound. The second coiler mandrel 9B is still unchanged with its right swing part 44 in the lower position to the right of the winding position.

As shown in FIG. 6, the strip material 2 continues to be wound on the first coiler mandrel 9A while the entire coiler mandrel 9A is pivoted, while the right swivel part 44 with the second coiler mandrel 9B fastened thereto is now pivoted out of the lower position and further up into the upper position swings in it.

According to the illustration according to FIG. 7, all ready-wound coils 3 previously drawn by way of example are removed from the winding position 12, and the strip material 2 has meanwhile been correctly placed on the first Winding mandrel 9A wound so that the newly wound coil 3 can be moved from the Anwickelposition 1 1 in the winding position 12.

According to the illustration according to FIG. 8, the left oscillating part 43 together with the rotor reel 4 starts to pivot out of its upper position according to the direction of arrow 62, whereby the strip material 2 continues to be wound on the first coiler mandrel 9A with full reel pull. This means that the rotor reel 4 is rotated from the Anwickelposition 1 1 by 180 ° in the winding position 12. This succeeds well, since the left rocker part 43 is pivoted with the first coiler mandrel 9A and with the rotor reel 4 counter to the strip running direction of the strip material 2. This means that the first swing member 43 rotates synchronously with the rotor reel 4 from the upper position to the lower position. At the same time, the right rocker part 44 is pivoted against the direction of the rotor reel rotation in the direction of the upper position until it is located axially to the right next to the winding position 11 (see FIG. 9). That is, the second swing member 44 rotates asynchronously with the rotor reel 4.

According to the illustration according to FIG. 9, the second coiler mandrel 9B is already axially to the right of the coiling position 11, ie the right swivel part 44 is pivoted into its upper position, while the first coiler mandrel 9A with the left swivel part 43 continues in the direction of the lower swivel part Position pivots.

As shown in FIG. 10, the left swing member 43 has arrived at the lower position so that the first coiler mandrel 9A is in the winding position 12, and the coil 3 wound on the first coiler mandrel 9A can be finished wound in this winding position 12. Meanwhile, the second coiler mandrel 9B is displaced in the axial direction 8 into the Anwickelposition 1 1 by means of the axial displacement device 47, so that the second coiler mandrel 9B already ready for a next Anwickelvorgang while the coil 3 on the first coiler mandrel 9A still finished wound becomes. According to the illustration according to FIG. 11, the second coiler mandrel 9B is moved further in the axial direction 8 toward the driven holding means 17 located on the first rotor side part 6. Meanwhile, at the same time, the band material 2 is wound on the first coiler mandrel 9A at the same time. As shown in Figure 12, the coil 3 is wound on the first coiler mandrel 9A. The winding speed of the strip material 2 is shut down to cutting speed and cut off, so that the coil 3 is ready for removal in line. Immediately after the cut, the strip material 2 can be wound onto the second coiler mandrel 9B positioned in the coiling position 11, whereby almost uninterrupted winding operations can be achieved.

According to the illustration according to FIG. 13, in the winding position 11, the freshly wound coil 3 is further wound on the second coiling mandrel 9B, while the first coiling mandrel 9A is pulled out of the winding position 12 and accordingly also the coil 3 which has just been wound and outside the rotor reel 4 is positioned on the left swing part 43. The already wound in the winding position 12 coil 3 is in Abtransportrichtung 63, which incidentally is the same direction with the Bandzuführrichtung moved out of this winding position 12 addition. As shown in Figure 14, the left swing member 43 is pivoted out of the lower position and moved back to the upper position, so that the first coiler mandrel 9A is again placed axially adjacent to the Anwickelposition 1 1.

Subsequently, the method steps explained above with FIGS. 3 to 13 can be repeated with inverted reel mandrels 9A and 9B.

Optionally, a sleeve member 64 may be slid onto the empty reel mandrels 9A and 9B, respectively, on their respective path from the lower position to the upper position by means of a sleeve handling system, not shown here. It should be explicitly pointed out at this point that the features of the solutions described above or in the claims and / or figures can optionally also be combined in order to be able to implement or achieve the explained features, effects and advantages in a cumulative manner. It is understood that the exemplary embodiment explained above and in particular the functional modes or method sequences explained by way of example are only first embodiments of the device 1 according to the invention for winding a strip material 2. In this respect, the embodiment of the invention is not limited to these embodiments.

The device according to the invention can be used not only for winding strip material into a coil, but also for unwinding strip material from a coil. The unwinding is typically done in substantially the reverse sequence of steps, such as winding the coil previously described.
