Description

The invention relates to a device for winding a strip material into a coil with a rotor reel, which comprises two rotor side parts which are rotatable about a common rotor axis and which are arranged at a distance from one another in the axial direction of the rotor axis in such a way that reel mandrels driven in rotation can be held between them.

The invention further relates to a method for winding a strip material to form a coil with a rotor reel rotatable about a rotor axis, a first reel mandrel being first pivoted axially into a position next to a winding position by means of a first pivotable rocker part, and then by means of a first axial displacement device, for winding the coil is moved into the winding position in the axial direction of the rotor axis; wherein the coil is wound in the winding position on the first reel mandrel held between a first and a second rotor side part of the rotor reel, and the wound coil is then rotated from the winding position into a winding position of the rotor reel by means of the rotor reel for final winding.

Devices and methods of the generic type are known from the prior art. As a rule, these are provided at the end or at the outlet of a hot or cold rolling mill or another machine for the production of strip-like flat products, such as metal strips, in order to convert these strip-like flat products into a coil or bundle in a winding process using a reel mandrel wind up and thereby be able to provide compact for further processing.

Different system concepts can be used to implement such a device. For example, such a device can be designed as a one-reel system or, to increase production, as an individually standing two-reel system with a belt switch. Or it’s a carousel coiler, which is often also referred to as a rotor or reversible reel system, is provided in which a reel mandrel for winding the strip material is in the optimal winding position, after which it is then transferred to a winding position after winding, and at the same time a further winding mandrel is shifted into the winding position to be prepared for further winding of a next coil. As a result, the single-reel system has the longest coil follow-up time, since after the coil has been pulled off, preparations must first be made for the winding of a new coil. Significantly shorter bundle follow-up times can be achieved with the two-reel systems with belt reel and the carousel reel systems, since these preparations can take place in a time-neutral manner.

In the known system concepts, the reel mandrels on one drive side of the respective device are always fixed, i.e. non-detachably, integrated in their rotary drive devices, the bearings of which are designed in such a way that the enormous weight and manpower acting on the projecting reel mandrels are operationally reliable via the bearings of the Rotation drive devices or gearbox bearings in this regard can be derived on the drive side into the frame of the respective winding device. However, this design has the disadvantage that the full strip tension required for winding is often only possible after repeated rotation of the holding mandrel and additional storage of the free end of the projecting coiler mandrel in a support bearing. In particular up to this additional bearing of this free end, this coiler mandrel is loaded by very high moments. With regard to the current trend towards ever wider strips to be wound up to a width of more than 2 m, the coiler mandrel and thus in particular its gearbox bearings are exposed to extremely high loads. Added to this is the further trend towards the production of high-strength tape grades, which require extremely high tape pulls for winding.

In addition to this drive side, there is also an operating side, which is formulated by the free projecting end of the reel mandrels. The reel mandrels are operated from the operating side. That is, from this On the operator side, empty winding tubes are pushed axially onto the reel mandrels, for example by means of a tube handling system. Or, starting from there, for example with the aid of a coil lift truck, completely wound coils are pulled axially from the reel mandrels and fed to a further transport device or intermediate storage device.

For example, is from the publication CN 101 642 783 a generic device for winding a strip material with a carousel reel is known, which has a reel mandrel drive with a quite complex transfer case unit to transmit the rotary drive power. This on the drive side of the complex and complex transfer case unit requires the highest level of manufacturing precision in order to manufacture the large number of precisely functioning gear meshes. In this respect, each transfer case unit is an elaborate special construction. The reel mandrel drive is therefore very expensive to manufacture. In the event of a repair or maintenance, the entire device is at a standstill since no replacement or emergency operation is possible. Accessibility for maintenance work is also difficult due to the complexity of the transfer case unit. Furthermore, the coiler mandrel drive shown there is characterized by a relatively elongated structure starting from the drive motor of the coiler mandrel drive up to the free coiler mandrel ends, as a result of which high gear bearing forces can act specifically on the gearbox bearings of the coiler mandrel drive. Furthermore, the reel mandrel drive has a complex supply and discharge of media with regard to its gear lubrication with a large number of lubrication points and a rotation of the carousel reel, and also a complex supply of hydraulic oil through expensive and wear-prone rotary oil supply.

It is also from the publication DE 10 2006 038 493 A1 a generic device for winding a strip material with a reversible reel is known, in which the reel mandrels consist of two reel half-mandrel parts. This means that two axially opposite reel half-mandrel parts together form a single reel mandrel for reeling one Form coils. Since the reel half-mandrel parts do not protrude so far from the respective drive side, less high bending moments act on the reel half-mandrel parts and their reel mandrel drives. The reel half-mandrel parts each forming a reel mandrel are not connected to one another, so that each reel half-mandrel part has a separate drive. The separate and simultaneous drive from both sides, that is from the drive side on the one hand and from the operator side on the other hand, often causes undesirable distortions within the wound coil. The short reel half-mandrel parts are moved towards 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 tapes to be wound and / or higher tape pulls, as a result of which these guide devices in particular have to be designed accordingly. However, this is expensive and such guiding devices constructively reach their limits.

The invention has for its object to further develop generic devices and methods for winding a strip material in order to at least partially overcome the aforementioned disadvantages.

The object of the invention is achieved by a device for winding a strip material into a coil with a rotor reel, which comprises two rotor side parts which can be rotated about a common rotor axis and which are arranged at a distance from one another in the axial direction of the rotor axis in such a way that reel spindles driven in rotation can be held between them , wherein the device outside the rotor reel comprises two independently swingable rocker parts which are pivotally mounted to the two rotor side parts, each of the rocker parts comprising an axial displacement device, by means of which the reel mandrel held on the respective rocker part can be inserted or removed in the axial direction in the rotor reel this is extractable.

Due to the two rocker parts which can vibrate independently of one another outside the rotor reel and which are pivotable to the two rotor side parts are stored, a particularly advantageous handling of the reel mandrels is achieved, namely that, for example, a second reel mandrel can be pivoted almost arbitrarily with respect to the rotor reel, while a first reel mandrel is in use within the rotor reel, more precisely while a strip material is being wound on the first reel mandrel . In addition, the reel mandrels can be inserted into or pulled out of the rotor reel, so that the reel mandrel located outside the rotor reel can be rotated between different positions while the other reel mandrel is in use. By means of the axial displacement device, the respective coiler mandrel can be displaced in a structurally simple manner in relation to the associated rocker part. As a result, the handling of the reel mandrels on the present device can be further automated and simplified.

In the context of the invention, the term “strip material” describes any strip-like flat products which are wound up into a coil, a bundle or the like in the course of their production process. These strip-like flat products can preferably be rolled strips made of steel or non-ferrous metals.

The term "reel mandrel" describes a rotary component in which either the strip material to be wound is wound directly. Or a sleeve element is pushed onto the reel mandrel beforehand, on which the strip material to be wound is then wound while rotating the reel mandrel.

In the present case, the reel mandrel is made in one piece and, in this respect, does not consist of two reel half-mandrel parts held at the end faces, as is sometimes the case in the prior art.

The term "rotor reel" in the prior art is synonymous with the terms "reversible reel" or "carousel reel".

The terms "coil" and "bundle" are used synonymously in the sense of the invention.

The term "winding" encompasses both winding the strip material into a coil on a reel mandrel and unwinding the coil from such a reel mandrel.

In this respect, the device according to the invention for winding the strip material into a coil can be placed not only on an outlet side of a rolling mill or the like, but also for unwinding a strip from a coil on an inlet side of a rolling plant or the like. In this respect, the present device can be used and used at a wide variety of locations in production plants and for a wide variety of purposes.

By means of the two rocker 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 created, by means of which a reel mandrel can be moved, for example, from a first working position to 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 can be, for example, a position to the side of a winding position, in which the coil which has been wound on is completely wound.

In the present case, the term “winding position” describes a position of the respective reel mandrel within the rotor reel, in which a strip material wound on the reel mandrel is finished wound into the coil. In contrast to this, the winding position should be mentioned, in which the strip material is only wound on the respective reel mandrel.

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

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

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

Each of the rocker parts advantageously has its own rocker drive device.

Furthermore, it is advantageous for reliable handling if the two rocker parts each comprise a holder with a preferably linear guideway, which extends in the axial direction along the respective rocker part, to translate one coiler mandrel outside of coiler mandrel holders of the two rotor side parts with respect to the rotor reel to be relocatable.

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

For example, by means of the axial displacement device, a displacement mechanism for a reel mandrel can be structurally simple on each rocker part be realized, which moves the respective coiler mandrel held by the rocker part axially in the direction of the rotor axis into its operating position or out of it. For example, for the relative translational displacement compared 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 rocker part. The swing arm part provides a cross member along which the guideway extends. The guideway preferably opens into the rotor axis of the rotor reel.

In addition, it is advantageous if the axial displacement device comprises a slide part which can be moved translationally along the guideway.

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

It is structurally advantageous if a spreader mechanism for radially spreading an outer surface area or for collapsing the previously spread outer surface area of the respective reel mandrel is immediately arranged in the slide part.

In any case, it is advantageous if the slide part is permanently connected to the reel mandrel. The slide part is preferably a functional component of the reel mandrel.

Another important feature can be seen in the fact that a rocker part rotates together and synchronously with the rotor side parts of the rotor reel when the reel mandrel assigned to this rocker part is operatively connected, in particular with its drive-side first end, to the output element of the associated reel mandrel drive. However, is the reel mandrel from that Disengaged output element and move axially next to the rotor reel, then the rocker part comprising this reel mandrel can rotate independently of the two rotor side parts of the rotor reel about the rotor axis of the rotor reel.

The object of the invention is also achieved by a method for winding a strip material into a coil with a rotor reel rotatable about a rotor axis, with a first reel mandrel first being pivoted axially into a position next to a winding position by means of a first swiveling rocker part, and then pivoted is shifted into the winding position in the axial direction of the rotor axis by means of a first axial displacement device; wherein the coil is wound in the winding position on the first reel mandrel held between a first and a second rotor side part of the rotor reel, wherein the wound coil is then rotated from the winding position into a winding position of the rotor reel by means of the rotor reel for finishing winding, and wherein the method is particularly characterized in that the first rocker part rotates outside the rotor reel; the first coiler mandrel is pivoted outside the rotor reel into the position axially next to the winding position with the aid of the first rocker part; and the reel mandrel is then displaced by means of the first axial displacement device relative to the first rocker part in the axial direction of the rotor axis between the first and the second rotor side part in such a way that a drive-side first end of the first reel mandrel is operatively connected and connected to an output element of a reel mandrel drive arranged on the first rotor side part second end of the first reel mandrel is held 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 take place in parallel on the device.

An advantageous first method variant provides that the first rocker part, from which the first reel mandrel was axially shifted into the winding position, rotates in the same direction as the rotor reel about the rotor axis when the first reeling mandrel is rotated from the winding position to the winding position. As a result, the first reel mandrel can remain in operative contact with the first rocker part, which can further simplify the present method.

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

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 process can be further simplified.

A winding process of another coil can already be prepared by the device if a second reel mandrel mounted outside the rotor reel is placed in a position axially next to the winding position by means of a second rocker part arranged outside the rotor reel, during or after the first reel mandrel with the wound coil by of the rotor reel is or has been rotated from the winding position into the winding position.

If the second rocker part with the second reel mandrel is rotated from a position axially next to the winding position to the position axially next to the winding position, while the first rocker part is rotated in the opposite direction to the winding position, the winding process can be tightened further.

A further process optimization can be achieved if the second reel mandrel is relative to the by means of a second axial displacement device second rocker part is moved in the axial direction of the rotor axis from outside the rotor reel into the winding position between the first and the second rotor side part, during or after the coil has been or has been completely wound on the first reel mandrel, with a drive-side first end of the second reel mandrel being connected to one the second rotor side part arranged output element of another reel mandrel drive is operatively connected and a second end of the second reel mandrel is held on the first rotor side part.

A high throughput can be achieved if a new coil is wound by repeating the method steps explained here, the second devices, in particular the second reel mandrel, taking the place of the first devices and vice versa.

With the present invention, a highly productive rotor reel can be constructed in a structurally very simple manner and the reel mandrels can be arranged on it in a completely removable manner.

Advantageously, both holding means driven by a reel mandrel drive and non-drive holding means, that is to say not driven by the reel mandrel drive, are advantageously arranged on each of the rotor side parts, as a result of which the rotor reel can be constructed in a structurally very simple manner and the reel mandrels can be arranged thereon in a completely removable manner. This results in a completely new system concept.

In particular, this eliminates the previous distinction between a drive side and an operating side of the device for winding the strip material into a coil, as a result of which the rotor reel in particular can be constructed symmetrically. In this way, forces and moments occurring within the device for winding the strip material can be controlled and absorbed much better. In this respect, on the one hand, wider tapes to be wound and / or higher tapes can be realized with the device according to the invention.

Furthermore, the reel mandrels are supported from the start, that is to say when a new coil is being wound, at their two ends, that is to say on the drive side and also on the support or bearing side, in appropriately designed reel mandrel holders on the rotor side parts and are therefore supported. This ensures the fastest possible build-up of a sufficiently high band tension, on the one hand to wind stable collar eyes (inner windings) and on the other hand high-strength band materials with high band tension.

In this context, it is advantageous if the rotor reel has a winding position for winding the metal strip onto the reel mandrel, in which the reel mandrel is held on both sides in two opposing reel mandrel holders of the two rotor side parts.

In addition, there is good accessibility to the individual components or component groups, as a result of which simplified maintenance and, if necessary, repair can be achieved.

Furthermore, the potential for larger bandwidths preferably increases in connection with smaller reel mandrel diameters.

The present device is characterized in particular by the extraordinary feature that the reel mandrels are mounted on the rotor side parts in such a way that they can be detached and removed completely from both rotor side parts in order to operate the device. The operation of the device includes, for example, supplying sleeves on which the strip material can be wound after a corresponding sleeve has been pushed onto the reel mandrel. Or it may involve pulling 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, ie the removal of a completely wound coil, can take place in the rolling line, and in which the coils are on one continuous reel mandrel with or without a sleeve can be wound and finished. This means that the coil only needs to be lowered 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 reel mandrel holders arranged on the rotor side parts for fixing the respective holding mandrel.

In the context of the present invention, the term “driven holding means” describes a reel mandrel holder on the rotor side part, which comprise an output element of a drive train of a reel mandrel drive and by means of which a correspondingly shaped, driven end of a holding mandrel is mounted on the rotor side part by the reel mandrel drive.

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

In contrast to the previously known solutions, it is advantageous if the reel mandrels are detachably mounted on the two rotor side parts in reel mandrel holders such that these reel mandrels can be completely removed from both rotor side parts for operating the device. The operation includes, for example, supplying sleeves pushed onto the reel mandrel, on which the strip material can be wound. Or it may involve pulling a wound coil from a coiler mandrel.

Another advantageous embodiment provides that the two rotor side parts are arranged rotated relative to one another by 180 ° in such a way that the driven holding means of the first rotor side part and the non-driven holding means of the second rotor side part as well as the non-driven holding means of the first rotor side part and the driven holding means of the second rotor side part are arranged opposite one another. As a result, the present rotor reel can be provided symmetrically in a structurally simple manner.

If the two rotor side parts are of identical design, at least with regard to their essential functional components, the number of different components or component groups can advantageously be further reduced. In this way, a reduction in spare parts inventory can also be achieved. The identity essentially refers 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 a fixed manner relative to one another in the axial direction of the rotor axis. However, this does not have to be mandatory.

The design of the rotor reel can be further simplified 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.

The reel mandrels can be attached and removed particularly quickly to and from both rotor side parts if the holding means arranged on both rotor side parts and the reel mandrels held thereon are interactively firmly but releasably connected by means of detachable coupling devices.

It is understood that such coupling devices can be of various shapes. Some examples are explained below of how quick-coupling holding means in this regard could be implemented.

On the drive side, the reel mandrels can be quickly coupled to or decoupled from an output element of the drive train if the driven holding means comprise a receiving element, by means of which a drive pin part of the reel mandrel can be positively and / or frictionally coupled to the drive train of the coiler mandrel drive, but can be detachably coupled. If necessary, the holding mandrels can also be clamped using spreading washers.

The reel mandrels can be securely fixed to the output element if the driven holding means comprise a clamping unit on the rotor side parts, by means of which a drive pin part of the reel mandrel can be clamped firmly but releasably.

A free end of the reel mandrel opposite the drive pin can be fixed in a reliable manner on the non-drive holding means if the non-drive holding means comprise a further clamping unit on the rotor side parts, by means of which a bearing point of the coiler mandrel opposite the drive pin can be firmly but releasably clamped.

The device can be further structurally simplified if the two rotor side parts have a common drive device.

In addition, the present device is characterized by a coiler mandrel holder for holding or supporting the free end of the respective coiler mandrel. This free end lies opposite the end of the reel mandrel on the drive side. The non-driven holding means, however, already support the reel mandrel in its winding position on its non-driven reel mandrel side and thus not only perform the function of a counter-bearing during reeling, but also during winding under tension. A corresponding In this case, the reel mandrel holder is used to connect the actual round reel mandrel and its guidance on a rocker part, the advantageously releasable fixation to the non-driving holding means on the rotor side parts and the point of attack for the travel 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 has a sleeve handling system. The sleeve handling serves to offer new sleeves to that of the two coiler mandrels, which will next pivot into the winding position. When a coil has been completely wound and the reel 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 retracted reel mandrel swivels into this intermediate position by means of the rocker part and the sleeve is pushed onto the reel mandrel (transfer position). The sleeve with the reel mandrel then swivels into the winding position. Since one coiler mandrel swivels on the "drive side" and the other on the "operating side" on the swing arm, the core handling system has at least one parking position, for example in the rolling line, and at least two transfer positions, namely on the respective coiler mandrel. The sleeve handling system can be structurally very simply supplemented by a moving device with a fixed half-shell for receiving the sleeves. Instead of the half-shell, other components, such as pliers or the like, can also be used. When using different sleeve types with different diameters, the holder 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 system layout. Such a sleeve handling system is already well known and is therefore not explained separately here.

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

A number of additional advantages result from further features to be emphasized, which advantageously further develop generic devices for winding strip material.

In this context, the advantageous symmetrical design of the device should be mentioned in particular, which enables the use of a solid or continuous and thus extremely stable reel mandrel, which is always supported on both rotor side parts when the coil is being wound up. This means that the winding can already take place from the third turn, especially when the belt winder is retracted, under full tape tension. This is a major advantage compared to conventional reversing reels, in which the full strip tension can only be built up if the reel mandrel with its freely projecting end on the operating side is supported in an additional support bearing, i.e. only after the rotor reel has rotated into the winding position.

In addition, the actual rotary drive of the reel mandrel is always on the opposite side of the simple bearing of the reel mandrel. This means that the expansion side on which the expansion mechanism or the non-driven holding means are located, and the drive side on which the driven holding means are located, are always placed in opposite directions with respect to a reel mandrel. As a result, a more compact design, in particular of the coiler mandrel, can be achieved.

Furthermore, the reel mandrel has a coupling device especially on the drive side in order to be able to quickly couple to the driven holding means of the corresponding reel mandrel holder, for example in the form of a flat pin or a star-shaped drive pin. In this respect, the rotor side parts have such a coupling device in order to Fix the inserted reel mandrel quickly, transfer the drive power safely and, if necessary, release it again.

Decoupling the full 360 ° rotation of the rotor reel from the 180 ° pivoting of the rocker part advantageously eliminates the need to install expensive and maintenance-prone rotary oil feeds.

Furthermore, the quickly releasable operative connections between the holding means on the reel mandrel holders, i.e. the releasable drive connections on the one hand and the releasable free storage of the reel mandrel on the other hand, and the reel mandrels, generate a previously unknown potential with regard to a quick reel mandrel change.

In particular, a quick change from reel mandrels to accidents, after changing reel mandrel diameters or after installing special mandrels, for example with a rubber coating, can be achieved with the present device.

In addition, it is advantageous if the device comprises a turn stopper to avoid telescopic inner turns when pulling out the reel mandrel from an eye of a coil. In terms of design, it can already be based on known designs.

Furthermore, the device preferably comprises a pressure roller known per se, which can serve to press a strip material end against the coil surface when the last turns are wound. This prevents the free end of the strip material from turning over, in particular when the strip tension required for winding is canceled.

The device can also be equipped with a belt winder known per se. The belt winder supports the winding of the beginning of the strip material in the winding position. It is 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 control tables. In a winding process, the reel mandrel - possibly with an opened and clamped sleeve - rotates at the same speed as the belt of the belt winder, thereby helping to fix the first turns of the band material around the reel mandrel or around the sleeve. After about three turns, the belt winder is removed from the reel mandrel and the actual reeling process under belt tension begins.

In addition, the device can also be equipped with a coil or coil handling system. The finished wound coils are removed in line. This means that the coil only needs to be lowered to a simple transport device, for example in the form of a chain or the like, by means of a suitable lowering device. This means that there is no need for expensive coil handling via coil lifting trucks.

A multitude of advantages can be achieved with the present device, namely, for example, faster coil follow-up times than is the case with a conventional device with a conventional carousel reel, as a result of which overall plant utilization and 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, simplification of the installed components, component and / or component groups is achieved, as a result of which the maintenance intensity, downtimes and the investment costs can be significantly reduced. In addition, the fastest possible train build-up and, as a result, also a stable coil or flange eye can be achieved, as a result of which the risk of the coil or coil eye collapsing during follow-up processes, for example during hood annealing, can be reduced. It is particularly advantageous that, with a suitable design, the device in question can be used to expand the system potential in general and in particular in the direction of larger strip material widths, higher strip tension, smaller reel mandrel diameters, the use of product-specific reel mandrels, significantly reduced reel mandrel change times during ongoing production or the like .

In addition, the present device is characterized in that it is easier to maintain than a conventional carousel reel. In addition, it is characterized by an essentially symmetrical arrangement, which means the use of at least largely identical components on both sides of the rotor reel, which also results in a reduction in the supply of spare parts. It is particularly advantageous that the present device has an extremely simple transmission design. In addition, a very simple sleeve task is created. The device at hand enables particularly simple strip sampling in continuous operation, also for inline inspection. In addition, transmission of higher drive torques is possible, which is particularly advantageous for high-strength strip materials to be used in the future or for jumbo coils or the like.

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

The object of the invention is further achieved by the claimed use of the device according to the invention also for unwinding a coil. The advantages of this solution correspond to the advantages previously mentioned in relation to the claimed device and the claimed winding method.

In the Figures 1 to 14 A first exemplary embodiment of the present device 1 according to the invention for winding a strip material 2 into a coil 3 and the way in which it functions are shown and described by way of example, wherein according to the representations according to FIGS Figures 1 and 2 essentially the structural design of the device 1 in connection with the first Functional relationships are explained. This is followed by the representations according to the Figures 3 to 14 again a possible procedure is explained in concrete terms.

The in the Figures 1 to 14 The device 1 shown 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 can be rotated about a common rotor axis 5.

The rotor reel 4 is rotatably mounted in a frame 1A of the device 1, the device 1 being fastened to a foundation (not shown here) by means of the frame 1A.

The two rotor side parts 6 and 7 are arranged axially spaced apart from one another in the axial direction 8 of the rotor axis 5 in such a way that reel mandrels 9A and 9B which are driven in rotation can be held between them.

As shown in the Figure 1 the right, ie the second reel 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 Figures 1 and 2 between the two rotor side parts 6 and 7, the rotationally driven second reel mandrel 9B rotates about its axis of rotation 10 when the coil 3 is wound or also when the coil 3 is finished winding next 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 360 ° in such a way that the reel mandrels 9A and 9B respectively stored within the rotor reel 4 are positioned either in a winding position 11 (upper position) or in a winding position 12 (lower position) can be.

A particularly simple construction of the rotor reel 4 results from the fact that the rotor side parts 6 and 7 at least with regard to their essential functional components are identical. In this respect, explained features and / or functions, which are shown and / or explained by way of example only on one of the two rotor side parts 6 and 7, always apply to both rotor side parts 6 and 7.

In order to be able to hold and store the reel mandrels 9A and 9B at their two ends 15 and 16 at the latest during a winding process in the winding position 11 in the rotor reel 4, the two rotor side parts 6 and 7 have a special construction, namely each of the rotor side parts 6 and 7 have driven holding means 17 on the one hand for driving a first end 15 of a reel mandrel 9A or 9B on the drive side, and on the other hand non-driven holding means 18 for merely holding another end 16 of a further reel mandrel 9A or 9B, the driven holding means 17 in contrast to the drive-less holding means 18 are each operatively connected to a drive train 17A or 17B of a reel mandrel drive 17C or 17D (see in particular Figure 2 ).

As per the Figure 2 is clearly visible, the device 1 thus has two coiler mandrels 17C and 17D; for each drive train 17A or 17B and accordingly for each rotor side part 6 or 7, a separate reel mandrel drive 17C or 17D.

Due to the two different types of holding means 17 and 18, the reel mandrels 9A and 9B can both be mounted interchangeably on the two rotor side parts 6, 7 in such a way that these reel mandrels 9A and 9B for operating the device 1 from both rotor side parts 6 and 7 are complete can be solved.

Due to the fact that the two rotor side parts 6 and 7 are of identical design, at least with regard to their essential functional components, and thus the respective reel mandrel 9A or 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-drive holding means 18 on the other hand, are effectively connected can, the two rotor side parts 6 and 7 are arranged rotated relative to one another by 180 ° around the rotor axis 5. 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 as well as 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 are 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 are arranged in the radial direction 19 radially spaced from the rotor axis 5 with respect to this rotor axis 5 on different sides 20 and 21 of the rotor axis 5 of the rotor reel 4.

The previously usual division between a pure drive side, from which the reel mandrels 9A and 9B are driven in rotation, and a pure operator side, from which the reel mandrels 9A and 9B are operated, i.e. from which finished wound coils 3 of the reel mandrels 9A and 9B are withdrawn and, if necessary, new winding tubes can be pushed onto the reel mandrels 9A and 9B.

So that the individual reel mandrels 9A and 9B can be quickly attached to or detached from the rotor side parts 6 and 7, 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 holding means 17 and 18 which are only mentioned by way of example below.

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 can be coupled to the drive train of the coiler mandrel drive in a positive and / or frictional manner.

The reel mandrels 9A and 9B can be temporarily fixed in a reliable manner on the driven holding means 17, since in this exemplary 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 reel mandrel 9A or 9B.

In order to be able to temporarily and reliably secure the reel mandrels 9A and 9B to the drive-less holding means 18, these drive-less holding means 18 have a further clamping unit, so that a bearing point opposite the drive pin can also be clamped.

Since the respective drive train 17A or 17B of the respective coiler mandrel drive 17C or 17D is at least partially arranged within the rotor side parts 6 and 7 and configured there, the rotor side parts 6 and 7 are each designed as a rectangular gearbox part 27 (numbered only as an example) which in particular the holding means 17 driven by the reel mandrel drive are arranged.

But not only the holding means 17 and 18 are arranged on this gear box part 27, but moreover an external ring gear 28 of a rotor drive 29 for the rotor reel 4 is firmly connected to the gear box part 27 or the respective rotor side parts 6 and 7.

In the present case, the rotor drive 29 is part 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 interacting with an external ring gear 28 fixed to the rotor side parts 6 and 7 such that the rotor reel 4 is rotated by the rotor drive 29 the rotor axis 5 can be rotated.

In order to be able to remove excess lubricant in particular for the gearbox parts 27 of the rotor side parts 6 and 7 and rotating gear components (not shown) of the respective drive train 17A or 17B of the respective coiler mandrel drive 17C or 17D, the rotor reel 4 only two rotary oil discharge devices 38 are provided, which in this exemplary embodiment are advantageously only fluidly operatively connected to the gearbox parts 27 with only four oil discharge lines 39 (only given as an example). 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 device 1 comprises, as an essential functional component, a transfer device 40, by means of which a reel mandrel 9A or 9B can be displaced additionally and independently of a rotation of the rotor reel 4, although the transfer device 40 is also rotatably supported with the rotor reel 4. As a result, the effectiveness that can be achieved with the device 1 increases significantly.

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

By means of the two rocker parts 43 and 44, the respective reel mandrel 9A and 9B can be carried in a reliable manner by the transfer device 40, transferred to the rotor reel 4 in the axial direction 8, 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 here by a left rocker drive device 45 (see Figure 2 ) swivel-driven. The right rocker member 44 is through a right rocker drive 46 (see Figure 2 ) independent of this, swivel-driven.

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 that can be displaced thereon.

The carriage 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, each coiler mandrel 9A or 9B being firmly connected to its associated carriage part 49. In this respect, each reel mandrel 9A or 9B always remains, that is to say in particular in each process step, firmly connected to the associated rocker part 43 or 44.

It goes without saying that the interaction between the guideway 48 and the slide part 49 can be designed differently. In this exemplary embodiment, a slide part travel drive, not shown here, is arranged within the slide part housing 50.

An expansion 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 also accommodated in a structurally compact manner in the slide part housing 50.

The respective swing part 43 or 44 is in a swing part holder 52 (see also Figure 2 ) pivotally mounted about the rotor axis 5 or about the pivot axis 41 which is identical with it.

By means of the Figures 1 and 2 The device 1 shown in the following exemplary first modes of operation are now possible.

As shown in the Figure 1 the second reel mandrel 9B is already in the winding position 11 and the coil 3 is already wound thereon. The right rocker part 44 was previously pivoted upward in such a way that the second reel mandrel 9B is placed axially to the right of the winding position 11. This second reel mandrel 9B was then inserted into the rotor reel 4 in the axial direction 8 using the axial displacement device 47 and was operatively connected to the two rotor side parts 6 and 7. For this purpose, the slide part 49 was moved along the guide track 48 in the direction of the rotor reel 4 by means of its slide travel drive. The drive-side first end 15 of the second reel mandrel 9B was inserted in the winding position 11 into the receiving element 25 of the driven holding means 17 of one of the holding mandrel holders and thus fixed there on the first rotor side part 6 by means of the corresponding clamping unit. The non-driven second end 16 of the second reel mandrel 9B, that is to say the end with a spreading mechanism 51 for radially spreading or an outer surface region or for collapsing the previously spread outer surface region of the second reel mandrel 9B, is fixed to the second rotor side part 7.

A motor of the first coiler mandrel drive 17C (see Figure 2 ) via the receiving element 25 in the gearbox part 27 of the first rotor side part 6 and thus also the second reel mandrel 9B held in the winding position 11.

After a belt winder (not shown) is withdrawn from the winding position 11 and / or after approximately three turns of the strip material 2, the reel tension applied to the strip material 2 is increased to a calculated required thickness. After a few turns (or after approval by the belt winder), the belt is repositioned with full belt tension wound coils 3 in the winding position 12 by the rotor reel 4 rotates 180 ° about the rotor axis 5. The second reel mandrel 9B previously shown in the winding position 11 is now in the winding position 12; similar to the representation according to the Figure 2 is indicated with regard to the first reel mandrel 9A. Here, that is to say while the rotor reel 4 is rotating, the strip material 2 continues to be wound up with full strip tension.

That is, the second reel mandrel 9B, the right swing arm part 44 and the two rotor side parts 6 and 7 rotate synchronously about the rotor axis 5 for this purpose.

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

The first coiler mandrel 9A, however, is as shown in FIG Figure 1 carried by the left rocker part 43 and is still axially to the left of the rotor reel 4 in a waiting position. This first reel mandrel 9A, which is arranged on the left rocker part 43, is later placed axially to the left of the winding position 11, starting from the waiting position. This first reel mandrel 9A can then be pushed in further steps into the winding position 11 by the axial displacement device 47 into the rolling line (similarly as already described above with regard to the second reel 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 reel mandrel 9A is supported in the non-driven, drive-less holding means 18 on the first rotor side part 6.

In the winding position 11, the first reel mandrel 9A waits for the start of the next winding process, while the coil 3 is completely wound in the winding position 12 (not shown, but see, however Figure 2 ).

The end of the coil 3 is pressed onto the finished wound coil 3 with the support of a pressure roller 60 in order to prevent the coil 3 from jumping open.

When 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 expansion mechanism 51 and the first or second coiler mandrel 9A or 9B then becomes axial from the coil 3 out of the rolling line pulled out to the right. At the end of the process, this first reel mandrel 9A is again fully seated on its left rocker part 43 and the second reel mandrel 9B is completely seated on its right rocker part 44 and is ready to be pivoted again next to the winding position 11.

While a sleeve handling system was dispensed with in the first mode of operation explained above by way of example, the device 1 can also be equipped with a sleeve handling system not shown here, as a result of which the example of operation explained below can be implemented.

If the strip material 2 is wound onto the coil 3, for example on a sleeve (not shown here), an andia position must be taken into account for corresponding sleeve handling when pivoting one of the rocker parts 43 or 44 in the form of further intermediate positions or the waiting position. For this purpose, after it has been pulled out of the eye of the wound coil 3 by means of the associated axial displacement device 47 at the end of a winding process, the reel mandrel 9A or 9B pivots into the waiting position using the rocker part 43 or 44. In the rolling line, preferably, an empty sleeve is already waiting for takeover by the respective coiler mandrel 9A or 9B. The sleeve is pushed onto the reel mandrel 9A or 9B by the sleeve handling system. This expediently already takes place while a new coil 3 is being wound in the winding position 11. After the sleeve has been fixed on the reel mandrel 9A or 9B, the corresponding swing part swings 43 or 44 with the coiler mandrel 9A or 9B and the sleeve pushed thereon into the winding position 11, in order to be subsequently inserted for winding into the rolling line and into the coiler mandrel holder of the corresponding rotor side part 6 or 7 opposite the axial displacement device 47. Then it can be rewound.

As shown in the Figure 2 The device 1 is shown by way of example in a further working phase, in which the first reel mandrel 9A is pulled out of the eye of the completely wound coil 3 to the left, while the second reel mandrel 9B is already in the winding position 11. Here, the right rocker part 44 is pivoted with its guide path 48 upwards and the left rocker part 43 with its guide path 48 downward.

It is very important for the present invention that the two rocker parts 43 and 44 are arranged on opposite end faces outside the rotor reel 4, so that they do not influence a winding phase within the rotor reel 4, regardless of the position in which they are located. In addition to the possible modes of operation already described above by way of example, the following is used Figures 3 to 14 a possible process sequence is illustrated in a very concrete way to convey the interaction of the individual device components even more clearly.

As shown in the Figure 3 is as an introduction to a possible process sequence in the Figures 1 and 2 1 shows a work situation in which the first reel mandrel 9A with the left rocker part 43 outside the rotor reel 4 is pivoted, for example, into an upper position axially to the left of the first rotor side part 6 or the winding position 11 in the direction of arrow 61. This work situation corresponds to starting the system with a first belt if there is no belt in the continuous process immediately before. The following belts are then processed continuously. The second coiler mandrel 9B is at the start of the System, for example, with the right rocker part 44 outside the rotor reel 4 in a lower position and axially to the right of the second rotor side part 7 or the winding position 12. The second reel mandrel 9B has already been pulled out of the completely wound coil 3, which is in line from the winding position 12 is transported out. In the continuous process, the first and second rotor side parts 6, 7 each swing together or in parallel.

As shown in the Figure 4 the left rocker part 43 is pivoted into the upper position, so that the first coiler mandrel 9A is located directly axially to the left of the winding position 11. As can be clearly seen, the first coiler mandrel 9A is moved in the axial direction 8 into the winding position 11 with the aid 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 (cf. Figure 5 ). The right reel part 44 of the second reel mandrel 9B is still unchanged in the lower position to the right of the winding position.

As shown in the Figure 5 the first reel mandrel 9A is operatively connected with its drive-side end 15 to the driven holding means 17 of the second rotor side part 7. An end of the strip material 2 fed to the first coiler mandrel 9A is already wound onto the first coiler mandrel 9A. The right reel part 44 of the second reel mandrel 9B is still unchanged in the lower position to the right of the winding position.

As shown in the Figure 6 the strip material 2 is further wound onto the first reel mandrel 9A with full reel tension, while the right rocker part 44 with the second reel mandrel 9B attached to it is now pivoted out of the lower position and pivots further up into the upper position.

As shown in the Figure 7 all of the pre-wound coils 3 previously drawn in by way of example have been removed from the winding position 12 and the strip material 2 has meanwhile been properly applied to the first one Coiler mandrel 9A is wound so that the newly wound coil 3 can be moved from the winding position 11 to the winding position 12.

As shown in the Figure 8 For this purpose, the left fescue part 43 starts to pivot together with the rotor reel 4 from its upper position in the opposite direction of the arrow 62, the strip material 2 being further wound onto the first reel mandrel 9A with full reel tension. This means that the rotor reel 4 is rotated from the winding position 11 by 180 ° into the winding position 12. This works well since the left rocker part 43 is pivoted with the first reel mandrel 9A and with the rotor reel 4 against the direction of the strip material 2. This means that the first rocker part 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 further against the direction of the rotor reel rotation in the direction of the upper position until it is axially to the right of the winding position 11 (cf. Figure 9 ). This means that the second rocker part 44 rotates asynchronously to the rotor reel 4.

As shown in the Figure 9 the second coiler mandrel 9B is already axially to the right of the winding position 11, that is to say the right rocker part 44 is pivoted into its upper position, while the first coiler mandrel 9A with the left rocker part 43 pivots further in the direction of the lower position.

As shown in the Figure 10 the left rocker part 43 has arrived in the lower position, so that the first reel mandrel 9A is in the winding position 12, and the coil 3 wound on the first reel mandrel 9A can be completely wound in this winding position 12. In the meantime, the second reel mandrel 9B is moved in the axial direction 8 into the winding position 11 by means of the axial displacement device 47 of the right fescue part 44, so that the second reel mandrel 9B is already ready for a next winding operation while the coil 3 is still being finished on the first reel mandrel 9A .

As shown in the Figure 11 the second reel mandrel 9B is moved further in the axial direction 8 towards the driven holding means 17 located on the first rotor side part 6. Meanwhile, on the first reel mandrel 9A, the strip material 2 is simultaneously finished.

As shown in the Figure 12 the coil 3 is completely wound on the first coiler mandrel 9A. The winding speed of the strip material 2 is reduced to the 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 reel mandrel 9B positioned in the winding position 11, as a result of which almost uninterrupted winding processes can be achieved.

As shown in the Figure 13 In the winding position 11, the freshly wound coil 3 is wound further on the second reel mandrel 9B, while the first reel mandrel 9A is pulled out of the winding position 12 and accordingly also the coil 3 which has just been wound and is positioned outside the rotor reel 4 on the left rocker part 43. The coil 3, which has already been wound in the winding position 12, is moved out of this winding position 12 in the removal direction 63, which incidentally is oriented in the same way as the tape feed direction.

As shown in the Figure 14 the left rocker part 43 is pivoted out of the lower position and moved back into the upper position, so that the first reel mandrel 9A is again placed axially next to the winding position 11.

Then the according to the Figures 3 to 13 previously described method steps are repeated with reversed reel mandrels 9A and 9B.

Optionally, a sleeve element 64 can be pushed onto the empty reel mandrels 9A and 9B in their respective path from the lower position to the upper position by means of a sleeve handling system, not shown here.

At this point it should be explicitly pointed out that the features of the solutions described above or in the claims and / or figures can also be combined if necessary in order to be able to implement or achieve the described features, effects and advantages in a correspondingly cumulated manner.

It goes without saying that the exemplary embodiment explained above, and in particular the functions or method sequences explained by way of example, are merely 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 exemplary embodiments.

The device according to the invention can be used not only for winding tape material into a coil, but also for unwinding tape material from a coil. The unwinding is typically carried out essentially in the reverse sequence of steps, such as the winding of the coil described above.
