Description

  The present invention is such that the rotor winder has two rotor side parts that can rotate about a common rotor axis, and these rotor side parts can hold a winder mandrel that is driven to rotate between them. The invention relates to a device for winding strip material into a coil by means of a rotor winder, spaced apart from one another in the axial direction of the rotor shaft.

  In the present invention, the first winder mandrel is first swung to a position axially next to the winding start position by the first swivelable swinging component, and then the first winding mandrel is wound. 1 is moved to the winding start position in the axial direction of the rotor shaft, and the coil is held between the first and second rotor side parts of the rotor winder at the winding start position. A rotor winder which can be rotated about a rotor shaft, which is wound around the winder mandrel of the winder, and the coil which has started winding is then rotated by the rotor winder from the winding start position to the winding position of the rotor winder to finish winding. Relates to a method for winding a strip material into a coil.

  Such devices and methods are known from the prior art. These are usually provided at the end or outlet of a hot or cold rolling mill or other machine for producing strip-like flat products such as strips, which are wound by winder mandrels. The process is wound into a coil or hoop so that it can be provided in a compact form for further processing.

  In particular, different equipment concepts can be used to realize such a device. For example, such a device can be formed as a single coiler or as an individually existing dual coiler with, for example, strip points to increase production. Or, a carousel coiler, often referred to as a rotor coiler or turning coiler, is provided, in which the coiler mandrel is in the optimal winding start position to start winding the strip material and the coiler mandrel is It is then transferred to the winding position, in which case another coiler mandrel is immediately moved to the winding start position so that it is ready for further winding start of the next coil. As a result, the single coiler has the longest hoop sequential time. This is because it is necessary to first prepare for the start of winding of a new coil following the coil drawing process. Obviously short coil turnaround times can be obtained in the case of dual and carousel coils with strip points. This is because these preparations can be made within the cycle time.

  In the case of the known equipment concept, the coiler mandrels are integrated into their rotary drive units, one end of which is always stationary, i.e. not dissociable, on the drive side of the respective device, and the bearings of these rotary drive units are protruding It is designed in such a way that a huge weight and actuating force acting on the mandrel can be reliably led to the respective frame of the device for winding via the bearing of the rotary drive or the drive side gear unit bearing associated therewith. However, this structure allows sufficient strip tension to wind, often after multiple rotations of the holding mandrel and additional bearings at the free end of the protruding coiler mandrel in the support bearing. It has the disadvantage of being possible for the first time. The coiler mandrel is loaded by a very high moment, in particular until this additional bearing at the free end. With regard to the current tendency to always roll a wide strip up to a strip width of more than 2 m, the coiler mandrel and thus especially its gear unit bearings are exposed to extremely high loads. This further tends to produce high-strength quality strips that require extremely high strip tension at the beginning of winding.

  In addition to this drive side, there is also an operating side, which is represented by a free protruding end of the coiler mandrel. From the operation side, the coiler mandrel is operated. That is, an empty winding sleeve is attached to the coiler mandrel in the axial direction from the operation side, for example, by a sleeve handling system. Alternatively, starting from the coil, for example, the coil that has been wound by the coil lift wheel is pulled out in the axial direction and supplied to another transfer device or intermediate storage device.

  For example, from Chinese Patent No. 101 642 783, a device of this kind for winding a strip material by means of a carousel coiler is known, which carousel coiler is however suitable for transmitting the rotary drive output. And a coiler mandrel drive device having a transfer box unit constructed at a cost. The drive side of a costly and complexly constructed transfer box unit requires all the highest precision in terms of manufacturing technology in order to form a large number of precision tooth meshes that function normally. In that respect, each transfer box unit is a costly special structure. Thus, the coiler mandrel drive is very expensive to manufacture. In the case of repair or maintenance, the entire device is stopped. This is because the backup mode or emergency mode is not possible. Also, the approachability for maintenance work is difficult due to the complexity of the transfer box unit. Furthermore, the coiler mandrel drive shown therein is distinguished by a relatively long configuration extending from the coiler mandrel drive to the free end of the coiler mandrel. A high gear unit bearing force can act on the gear unit bearing. Furthermore, the coiler mandrel drive unit is a costly medium supply unit or medium discharge unit, and expensive and easy to wear rotating oil supply with respect to gear unit lubrication with a large number of lubrication points and carousel coiler rotation. And a supply section that costs the hydraulic oil by the section.

  Furthermore, from DE 10 2006 038 493 a device of this kind for winding a strip material with a turning winder is known, in which case the winder mandrel is divided into two winder mandrel halfs. Consists of parts. That is, two winder mandrel halves opposed in the axial direction constitute one winder mandrel for winding the coil together. Since the winder mandrel half does not protrude so much from the respective drive side, a not so high bending moment acts on the winder mandrel half and the winder mandrel driving device. The winder mandrel halves that respectively constitute the winder mandrel are not coupled to one another, whereby each winder mandrel half comprises a separate drive. Separate and simultaneous driving from both sides, i.e. from the drive side on the one hand and from the operation side on the other hand, often results in unwanted coiled coils. The short winder mandrel halves are moved towards or away from each other by a guide device. This is extremely loaded when the coil mass is high and / or the strip to be wound is wide and / or when the strip tension is high, so that in particular these guide devices It creates what needs to be solidly designed. However, this is expensive and thus such guide devices are structurally limited.

  The problem underlying the present invention is to further develop such an apparatus and method for winding strip material, for example to at least partly overcome the above-mentioned drawbacks.

  An object of the present invention is to provide a rotor winder having two rotor side parts that can rotate about a common rotor shaft, and these rotor side parts can hold a winder mandrel that is driven to rotate between them. In addition, in the device for winding the strip material around the coils by the rotor winder, which is arranged spaced apart from each other in the axial direction of the rotor shaft, this device can be swung out of the rotor winder independently of each other There are two oscillating parts, and these oscillating parts are supported so as to be pivotable with respect to the two rotor side parts, and each of the oscillating parts has an axial movement device. By means of this, the invention is solved by a device characterized in that the winder mandrels held on the respective swing parts are movable in the axial direction.

  A particularly advantageous handling of the winder mandrel is obtained by means of two oscillating parts which can be swung independently of each other outside the rotor winder and which are pivotally supported relative to the two rotor side parts, for example The second winder mandrel is substantially optional while the first winder mandrel is in use in the rotor winder, more precisely, while the strip material is wound on the first winder mandrel. Can turn with respect to the winder. Further, the winder mandrel can be inserted into or withdrawn from the rotor winder so that each winder mandrel that exists outside the rotor winder can rotate between different positions, while the other winder. The mandrel is in use for winding. Due to the axial movement device, each winder mandrel can be structurally easily supported in the axial direction with respect to the swinging part to which it belongs. Thereby, the operation of the winder mandrel in the apparatus can be further automated and simplified.

  The concept of “strip material”, in the sense of the present invention, represents a strip-shaped flat product that is wound around a coil, hoop or the like during the course of its manufacturing process. These strip-like flat products can be rolled strips, preferably made of steel or non-ferrous metal.

  The concept of “winder mandrel” here represents a rotating part that directly winds up the strip material to be wound. Alternatively, a sleeve element is pre-mounted on the winder mandrel, on which the strip material to be wound is then wound under the rotation of the winder mandrel.

  The winder mandrel is not integrally composed here of two winder mandrel halves that are formed in one piece and are held face-to-face at the end face as is partially customary in the prior art.

  The concept of “rotor winder” should be equated with the concept of “turning winder” or “carousel winder” in the prior art.

  The terms “coil” and “hoop” are used synonymously in the sense of the present invention.

  The concept of “winding” includes winding the strip material around a winder mandrel into a coil and unwinding the coil from such a winder mandrel.

  In that respect, an apparatus according to the invention for winding strip material into a coil can be arranged not only on the exit side of a rolling facility, for example, but also on the entry side of a rolling facility, etc. for stripping from the coil. In that regard, the apparatus can be used at different locations in the manufacturing facility and for different purposes.

  By means of two oscillating parts that can oscillate independently of one another outside the rotor winder, here a delivery device is provided which works independently of the rotation of the roller winder, by means of which the winder mandrel The rotor winder can be transferred from the first working position to at least one other working position without rotating.

  For example, the first work position is a position next to the winding start position of the apparatus where the coil starts to be wound. Another position is, for example, a position next to the winding position where the coil that has started winding is finished.

  The concept of “winding position” here represents the position of each winder mandrel in the rotor winder where the strip material wound onto the coil around the winder mandrel is finished. In contrast, the winding start position can be said to be a position at which the strip material can only be started to wind on the respective winder mandrels.

  The delivery device can be integrated very well into the device when the delivery device or its swinging part comprises a pivot axis that coincides with the rotor axis of the rotor winder.

  Furthermore, it is advantageous if the delivery device or its oscillating parts are rotatably supported with the rotor winder. As a result, the winder mandrel itself supported in the delivery device can continue to be held on the delivery device or on one of the rocking elements during the rotation of the roller winder.

  Furthermore, it is particularly advantageous if the two oscillating parts are pivotable about the rotor axis of the rotor winder, respectively, by at least 180 ° without depending on the rotatable rotor side parts. As a result, the winder mandrel held by the swinging component can be transferred from the winding position to the winding start position, for example. However, the rotor winder does not need to rotate.

  Advantageously, each of the oscillating components comprises a unique oscillating drive unit.

  Furthermore, in order to hold each one winder mandrel so that it can move translationally relative to the rotor winder outside the winder mandrel holding part of the two rotor side parts, the two rocking parts are each in the axial direction. It is advantageous for a reliable operation to have a holding part with a guide track, preferably formed linearly, extending along the rocking part.

  As already explained, each of the oscillating parts has an axial movement device by which each winder mandrel accommodates a holding means for driving the drive pin of the winder mandrel on the drive side. It is advantageous if it can be moved axially in the axial direction of the rotor shaft for insertion into the element.

  For example, by means of an axial movement device, each winder is held structurally in a simple manner, for example by a respective winder for translational movement relative to the receiving element of the driven holding means. A movement mechanism for a winder mandrel can be realized that moves the mandrel axially in the direction of the rotor axis to or from its operating position.

  The axial movement device may be formed differently. It is particularly advantageous if the axial movement element comprises a guide track, which guide track extends in the axial direction along the respective oscillating component, preferably linearly. In this case, the oscillating element provides a traverse element along which the guide track extends. Preferably, the guide track reaches the rotor axis of the rotor winder.

  Furthermore, it is advantageous if the axial movement device has a carriage part, which can be moved translationally along the guide track.

  In this case, the carriage component driving device may be formed differently. The carriage part driving device is accommodated in each swing part or in the carriage part itself.

  It is structurally advantageous if a carriage mechanism is also arranged in the carriage part for radially expanding the outer surface area of each winder mandrel or for correcting the pre-expanded outer surface area. is there.

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

  Another important feature is that one oscillating element is operatively coupled to a driven element of a winder mandrel drive device, which is attached to the winder mandrel attached to this oscillating element, in particular with a first end on its drive side. In this case, it can be seen that it rotates with and synchronously with the rotor side parts of the rotor winder. However, if the winder mandrel is released from the driven element and moved axially next to the rotor winder, the swinging part with this winder mandrel will not depend on the rotor side parts of the rotor winder. Can rotate without.

  The subject of the present invention is further that, for the start of winding of the coil, the first winder mandrel is first swung to a position axially next to the winding start position by the first swivelable swinging part, and then The first axially moving device is moved to the winding start position in the axial direction of the rotor shaft, and the coil is held between the first and second rotor side parts of the rotor winder at the winding start position. The first winder mandrel begins to be wound, and the coil that has begun to be wound is then rotated about the rotor shaft by the rotor winder from the winding start position to the winding position of the rotor winder to finish winding. In a method for winding a strip material into a coil by means of a rotor winder, in particular, the first rocker part rotates outside the rotor winder and the first winder mandrel is moved to the first rocker part. Therefore, the winder mandrel is swung to the position adjacent to the axial direction of the winding start position outside the rotor winder, and then the first end on the driving side of the first winder mandrel is arranged on the first rotor side part. The first pivoting device causes the first swing to be operatively coupled to the driven element of the winder mandrel drive and to hold the second end of the first winder mandrel to the second rotor side piece. It is solved by a method characterized in that it is moved relative to the part in the axial direction of the rotor shaft between the first and second rotor side parts.

  According to the invention, the winding process for winding the strip material into the coil is significantly accelerated. This is because the process course here can be carried out in the apparatus partly in parallel.

  An advantageous first method variant is that the first oscillating component moves the first winder mandrel axially to the winding start position when the first winder mandrel is rotated from the winding start position to the winding position. However, it is configured to rotate together in the same direction around the rotor axis in synchronization with the rotor winder. Thereby, the first winder mandrel remains in the working contact state, whereby the method can be further simplified.

  Further, after the winding is completed, the first winder mandrel is pulled out from the coil after winding in the axial direction, and temporarily stops on the first swinging component that is rotated to the winding position in the lateral direction outside the rotor winder. This is advantageous. This allows the coil to be released from the winding position for further transport in a particularly simple manner.

  The method can be further simplified if the strip material is cut off after winding and the coil after winding is unloaded from the rotor winder.

  Another coil winding start process was carried out of the rotor winder while the first winder mandrel having the coil started winding was rotated by the rotor winder from the winding start position to the winding position or after being rotated. If the second winder mandrel is arranged at a position axially next to the winding start position by means of a second oscillating part arranged outside the rotor winder, it can already be prepared by the device.

  While the first oscillating component is rotated to the winding position in the opposite rotational direction, the second oscillating component having the second winder mandrel is moved from the position adjacent to the winding position in the axial direction to the winding start position. When rotated to an axially adjacent position, the winding start process can be simplified.

  Another process optimization is that the second coiler mandrel is moved relative to the second oscillating component by the second axial movement device during or after the coil has been wound on the first winder mandrel. Is moved relative to the axial direction of the rotor shaft from the outside of the rotor winder to the winding start position between the first and second rotor side parts, and the first end on the driving side of the second winder mandrel is When the second end of the second winder mandrel is held by the first rotor side part, operatively coupled with the driven element of another winder mandrel drive device arranged on the two rotor side parts, can get.

  A high charge is achieved when a new coil is wound by repeating the steps described here, and when the second device, in particular the second winder mandrel, moves to the position of the first device and vice versa. If you get it.

  According to the invention, a highly productive rotor winder can be constructed very simply in structure and the winder mandrel can be placed in the rotor winder in a completely removable manner.

  Advantageously, each of the rotor side parts is also provided with holding means that are driven by a winder mandrel driving device, as well as holding means that are not driven, i.e. not driven by a winder mandrel driving device. The winder mandrel can be placed in the rotor winder in a completely removable manner. This creates a completely new equipment concept.

  This eliminates, in particular, the previous distinction between the drive side and the operating side of the device for winding the strip material into a coil, so that, in particular, the rotor winder can be configured symmetrically. Thereby, the forces and moments generated in the device for winding the strip material can be controlled and received substantially better. In that respect, on the one hand, wide strips to be rolled and / or high strip tensions can be realized with the device according to the invention.

  Furthermore, the winder mandrel is supported on the rotor side parts from the beginning, ie already at the beginning of the winding of the new coil, at both ends, ie the drive side and the support or bearing side, in the correspondingly formed winder mandrel holding part. And are therefore supported. Thus, a sufficiently high strip tension is ensured as quickly as possible in order to wind a stable hoop eye (coil inner part) on the one hand and a high strength strip material on the other hand with a high strip tension.

  In this connection, the rotor winder has a winding start position for winding the strip around the winder mandrel, where the winder mandrel has two winders facing the two rotor side parts from both sides at the end side. It is advantageous if it is held in a mandrel holding part.

  Furthermore, a good approach to individual parts or groups of parts is imparted, so that, for example, simplified maintenance and in some cases repairs are obtained.

  Furthermore, the potential for large strip widths is preferably increased in relation to smaller winder mandrel diameters.

  In particular, the apparatus is supported such that the winder mandrels can be removed from the rotor side parts so that the winder mandrels can be completely detached and removed from the rotor side parts for operation of the machine. It stands out because of its outstanding characteristics. The operation of the device includes, for example, providing a sleeve around which the strip material can be wound after the corresponding sleeve is mounted on the winder mandrel. Alternatively, the operation includes, for example, withdrawing a wound coil from a winder mandrel.

  The apparatus can, for example, handle a coil, i.e. unwinding a wound coil, in a rolling line and of a rolling train that can start and finish winding a coil on a consistent winder mandrel with or without a sleeve. Present at the exit. That is, the coil only needs to be lowered onto a simple conveying device, for example in the form of a chain element.

  Both the holding means that are driven and the holding means that are not driven are components of the winder mandrel holding part for fixing the holding mandrels arranged on the rotor side parts.

  The concept of “driven holding means” represents, in the sense of the present invention, a winder mandrel holding part in the rotor side part, this winder mandrel holding part having a driven train driven element of the winder mandrel driving device. By means of this winder mandrel holding part, the correspondingly formed end of the winder mandrel driven by the winder mandrel driving device is supported on the rotor side part.

  Accordingly, the concept of “non-driven holding means” represents, in the sense of the present invention, another winder mandrel holding part in the same rotor side part, by means of this winder mandrel holding part, corresponding to another winder mandrel. Another undriven end formed on the rotor is supported on the rotor side part while avoiding interaction with the winder mandrel drive. That is, the holding means that is not driven is not driven so that the holding means rotates one of the winder mandrels. Rather, this holding means only bears another end of each winder mandrel, or this holding means only supports another end, in this case only rotating with the associated winder mandrel. is there.

  Unlike the previously known solutions, the winder mandrels are located in the winder mandrel holding part at the two rotor side parts so that they can be completely removed from both rotor side parts in order to operate the device. It is advantageous if it is detachably supported. The operation includes the provision of a sleeve attached to the winder mandrel, for example to wrap the strip material. Alternatively, the operation includes, for example, withdrawing a wound coil from a winder mandrel.

  Another advantageous implementation variant includes a driven holding means for the first rotor side part and an undriven holding means for the second rotor side part and an undriven holding means for the first rotor side part and the second. The two rotor side parts are arranged so as to be displaced from each other around the rotor axis by 180 ° so that the holding means for driving the rotor side parts of the rotor are arranged opposite to each other. . As a result, the rotor winder can be prepared symmetrically particularly easily in structure.

  If the two rotor side parts are formed identically at least with respect to their substantial functional elements, the number of different parts or groups of parts can be advantageously further reduced. This also reduces the storage of spare parts. In this case, the identity applies substantially to important functional parts or functional areas of the rotor side parts.

  In particular, the stability of the rotor winder can be further improved if the means for holding the two rotor side parts of the rotor winder are arranged in position relative to each other in the axial direction of the rotor shaft. However, this is not mandatory.

  The rotor winder can be further simplified if the driven holding means and the non-driven holding means of the rotor side parts are arranged on different sides of the rotor shaft at a radial distance from the rotor shaft.

  If the holding means arranged on the side parts of both rotors and the winder mandrels held by them are connected to each other by a detachable coupling device in an interactively stationary but detachable manner, the two rotors A particularly quick installation and removal of winder mandrels to or from the side parts is possible.

  It will be appreciated that there can be various forms of such coupling devices. In the following, some examples are given of how a quick coupling type holding means in this regard can be realized.

  When the holding means to be driven has a receiving element which can couple the drive pin part of the winder mandrel in a meshing and / or frictionally engaged manner with the drive train of the winder mandrel drive device, but releasably. The winder mandrel can be quickly connected or disconnected from the driven element of the drive train on the drive side. In some cases, the winder mandrel can also be clamped by the spreading disc.

  The winder mandrel can be reliably fixed to the driven element when the holding means to be driven has a clamping unit in the rotor side part which can pinch the drive pin part of the winder mandrel immovably but releasably. .

  The free end of the winder mandrel relative to the drive pin has another clamping element on the rotor side part in which the non-driven holding means can pinch the bearing location of the winder mandrel relative to the drive pin, but releasably. In some cases, it can be reliably fixed to the non-driven holding means.

  The device can be further structurally simplified when the two rotor side parts comprise a common drive unit.

  Furthermore, the device is distinguished by a winder mandrel holding part for holding or supporting the free end of each winder mandrel. This free end is opposite to the drive end of the winder mandrel. However, the non-driven holding means supports the winder mandrel on the winder mandrel side which is not driven already in its winding start position, and therefore not only at the time of winding but also at the start of winding already under tension, in the thrust bearing. Satisfy the function. A corresponding winder mandrel holding part here is for the connection between the original circular winder mandrel and its guide on the oscillating part and for the undriven holding means and the moving mechanism in the rotor side part. It is preferably used to fix releasably to the point of action. In addition, the winder mandrel holder guides and locks the winder mandrel to the operating position.

  Furthermore, the function of the device can be further improved when the device comprises a sleeve handling system. The sleeve handling part is used to provide a new sleeve for both winder mandrels that are swung to the winding start position as the next winder mandrel. Once the coil has been wound and the winder mandrel has been withdrawn from the coil eye, the new sleeve waits in an intermediate or stopped position. The retracted winder mandrel is turned to this intermediate position by the swinging part, and the sleeve is mounted on the winder mandrel (delivery position). Thereafter, the sleeve turns to the winding start position together with the winder mandrel. Since one “drive side” winder mandrel and the other “operating side” winder mandrel on the rocker pivot, the sleeve handling system has at least one stop position, for example a stop position in the rolling line, and at least It has two delivery positions, i.e. a delivery position in each winder mandrel. The sleeve handling system can be supplemented by a moving device having a half shell with strength to accommodate the sleeve in a substantially very structural manner. Instead of a half shell, other parts such as tongs can also be applied. When using different sleeve types with different diameters, the receptacle may be vertically positionable. Even if different delivery levels are required due to the equipment layout to provide the sleeve handling part, the same function is required. Such sleeve handling systems are already well known and are therefore not described individually here.

  In this connection, it is advantageous if the winder mandrel is withdrawn from the wound coil, is temporarily stopped outside the rotor winder in the lateral direction, and the wound coil is carried out of the rotor winder in a straight line. For example, the above-mentioned sleeve handling system can be used well when paused at a corresponding intermediate position.

  A number of additional advantages result from the other features to be emphasized that advantageously develop this type of device for winding strip material.

  In this connection, an advantageous symmetrical design of the device that allows the use of a consistent and therefore most stable winder mandrel, which is already supported on both rotor side parts already at the beginning of the winding of the coil, is mentioned in particular. Can do. This means that, even after the winding of the belt wrapper, after about three windings, the winding start can already take place under a sufficient strip tension. This is the first time when the winder mandrel is thrust-beared in an additional support bearing at its end, which protrudes freely on the operating side, i.e. only after the rotor winder has been rotated into the winding position. This is an important advantage over the usual turning winder you get.

  Furthermore, the winder mandrel's original rotational drive is always on the opposite side of the simple support of the winder mandrel. This means that the spreading side where the spreading mechanism or the non-driven holding means is present and the driving side where the driven holding means are present are always arranged on the opposite side with respect to the winder mandrel. As a result, a compact structure of the winder mandrel is obtained.

  Furthermore, the coupling device in the form of a drive pin, for example in the form of a flat pin or a star, in particular on the drive side, so that the winder mandrel can be quickly connected to the driven holding means of the corresponding winder mandrel holding part. Is provided. In that respect, the rotor side part is equipped with such a coupling device so that the inserted winder mandrel can be quickly fixed, the drive output can be reliably transmitted and disengaged again if necessary.

  Disengaging the full 360 ° rotation of the rotor winder from the 180 ° turn of the rocking component advantageously eliminates the need to incorporate a costly and serviceable rotary oil supply.

  Furthermore, by means of a rapidly disengageable working connection between the holding means in the winder mandrel holding part, i.e. on the one hand, a disengageable drive connection, and on the other hand, a releasable free bearing part of the winder mandrel, With a winder mandrel, it is possible to create a previously unknown potential for winder mandrel quick exchange.

  In particular, a rapid exchange of the winder mandrel in response to breakage, a change in winder mandrel diameter, or the incorporation of a special mandrel with eg a rubber coating is obtained with this device.

  Furthermore, it is advantageous if the device has a coil stopper to avoid the inner part of the coil that becomes telescopic when the winder mandrel is withdrawn from the eye of the coil. The coil stopper corresponds structurally to a known design.

  Furthermore, the device preferably has a pressing roller known per se, which pressing roller can be used to press the strip material against the coil surface when starting to wind the last coil part. This prevents the free end of the strip material from being folded back, particularly when the strip tension required for winding is released.

  The device can also comprise a belt wrapper known per se. The belt wrapper assists the beginning of winding of the strip material leading edge in the winding position. The belt wrapper is preferably moved to the operating position when the strip material is moved to the winding start position. In this case, the belt wrapper supports and guides the strip material by a guide and a control desk. During the winding process, the winder mandrel, possibly with an attached and clamped sleeve, rotates at the same speed as the belt of the belt wrapper travels, so that the first coil portion of the strip material is wound into the winder. Help secure around mandrels or sleeves. After about 3 windings, the belt wrapper is removed from the winder mandrel and the original winding process begins under strip tension.

  In addition, the device may further comprise a coil handling system or a hoop handling system. The wound coil is unloaded in a straight line. That is, the coil only needs to be lowered onto a conveying device, for example in the form of a chain, simply configured by a suitable lowering device. Thereby, the expensive coil handling via a coil lift vehicle can be saved.

  The device provides a number of advantages, i.e. faster coil sequential times than would be the case with conventional devices having, for example, a normal carousel winder, which makes full use of the facility capacity possible. The overall increase is obtained and linked to this. In addition, the device stands out by the use of simple parts, i.e., in particular, simplification of installed components, parts and / or groups of parts is obtained, which leads to maintenance requirements, downtime and investment. Cost can be significantly reduced. In addition, tension increases as quickly as possible and a stable coil eye or hoop eye are also obtained, which can reduce the risk of shrinking the coil eye or hoop eye during subsequent processes, for example during bell annealing. When properly configured, the device generally provides an increase in equipment potential, especially the use of larger strip material widths, higher strip tensions, smaller winder mandrel diameters, product specific winder mandrels. Winder mandrel replacement time and the like that are significantly shortened during production progress can be obtained.

  In addition, the apparatus is further distinguished by the fact that the apparatus is easier to service than conventional carousel winders. In addition, it is distinguished by a substantially symmetric arrangement, which provides at least sufficient use of the same parts on both sides of the rotor winder, which also results in a reduction in the storage of spare parts. It is particularly advantageous for the device to have the simplest gear unit type. In addition, a very simple sleeve type is provided. This device also allows for particularly simple strip sample removal during continuous operation for in-line inspection. In addition, higher drive torque transmission is possible, which is particularly advantageous for high-strength strip materials, jumbo coils and the like that will be used in the future.

  The device described here can overcome the disadvantage that, in particular, the design of the winder mandrel and the gear unit bearing on its drive side, and thus the overall design of the rotor winder, has been technically discussed.

Partial view of

  FIGS. 1 to 14 show and explain by way of example a first embodiment of a device 1 according to the invention for winding a strip material 2 around a coil 3 and its functional scheme, by way of illustration according to FIGS. In essence, the structural configuration of the device 1 associated with the first functional relationship is described. Subsequent to this, the possible process progress is again specifically explained by the illustration of FIGS.

  The device 1 for winding the strip material 2 shown in FIGS. 1 to 14 on a coil 3 comprises a rotor winder 4 having two rotor side parts 6 and 7 which can be rotated about a common rotor shaft 5.

  The rotor winder 4 is rotatably supported in a frame 1A of the device 1, and the device 1 is fixed to a foundation (not shown) by the frame 1A.

  The two rotor side parts 6 and 7 are axially spaced apart from each other in the axial direction 8 of the rotor shaft 5 so as to hold the winder mandrels 9A and 9B that are rotationally driven between them. .

  According to the illustration according to FIG. 1, the right or second winder mandrel 9 B is already in contact with both rotor side parts 6 and 7 of the rotor winder 4, ie within the rotor winder 4 both rotor side parts 6 and 7. It is supported in between. 1 and 2, the second winder mandrel 9B, which is rotationally driven between the rotor side parts 6 and 7, is shown in FIG. Sometimes rotates. The left, that is, the first winder mandrel 9A is still arranged outside the rotor winder 4, that is, on the left side in the axial direction of the first rotor side part 6.

  In this case, the rotor side parts 6 and 7 of the rotor winder 4 are arranged such that the winder mandrel 9A or 9B supported in the rotor winder 4 is either the winding start position 11 (upper position) or the winding position 12 (lower position). ) May be rotated by at least 360 °.

  A particularly simple construction of the rotor winder 4 naturally arises from the fact that the rotor side parts 6 and 7 are formed identically at least with respect to their important functional elements. In that respect, the features and / or functions that are exemplary and / or described by way of example only in one of the two rotor side parts 6 and 7 always apply to both rotor side parts 6 and 7.

  The two rotor side parts 6 and 7 have a special construction so that both ends 15 and 16 of the winder mandrel 9A or 9B can already be held and supported in the rotor winder 4 during the winding start process at the winding start position 11 at the latest. Each of the rotor side parts 6 and 7 comprises, on the one hand, driven holding means 17 for driving the first end 15 on the drive side of one winder mandrel 9A or 9B, on the other hand Then, the non-driven holding means 18 is provided for simply holding another end 16 of another winder mandrel 9A or 9B, and the driven holding means 17 is different from the non-driven holding means 18 in each winder mandrel driving device. It is operatively coupled to a 17C or 17D drive train 17A or 17B (see in particular FIG. 2).

  Thus, as better seen in FIG. 2, the device 1 has two winder mandrel drives 17C or 17D, ie for each drive train 17A or 17B and thus for each rotor side piece 6 or 7 For this purpose, a unique winder mandrel driving device 17C or 17D is provided.

  By means of two different types of holding means 17 and 18, both winder mandrels 9A or 9B can be completely detached from both rotor side parts 6 and 7 in order to operate the device 1. Thus, each of the two rotor side parts 6 and 7 can be exchangeably supported.

  The two rotor side parts 6 and 7 are formed identically at least with respect to their important functional elements, so that each winder mandrel 9A or 9B, on the other hand, with its first end 15 on its drive side. On the basis of the fact that it can be operatively coupled to the driven holding means 17 and with its second end 16 to the non-driven holding means 18, the two rotor side parts 6 and 7 are 180. They are arranged so as to be rotated around the rotor shaft 5 by a degree. As a result, the holding means 17 that drives the first rotor side part 6 and the non-driven holding means 18 that drives the second rotor side part 7 are the first rotor means in the sense of the first holding means pair. The holding means 18 that is not driven by the side part 6 and the holding means 17 that is driven by the second rotor side part 7 are arranged so as to always face each other in the sense of the second holding means pair. Guaranteed.

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

  Therefore, the pure drive side (winder mandrel 9A or 9B is driven to rotate from this drive side) and the pure operation side (winder mandrel 9A or 9B is operated from this operation side, that is, this operation side. Thus, the winding 3 is removed from the coil 3 and the winder mandrel 9A or 9B is pulled out, and a new winding sleeve may be attached to the winder mandrel 9A or 9B in some cases.

  In order to allow individual mandrels 9A or 9B to be fastened to or disengaged from the rotor side parts 6 and 7 quickly, the latter is a coupling device (clearly Unsigned). These coupling devices are particularly well-prepared structurally by the features of the holding means 17 or 18, which will be described only by way of example below.

  For example, the driven holding means 17 has a receiving element 25 by which the drive pin part (not shown) of the respective winder mandrel 9 can be engaged and / or frictionally engaged. Coupling with the drive train of the winder mandrel drive device is possible.

  With reliability, the winder mandrel 9A or 9B can be temporarily fixed to the driven holding means 17. This is because in this embodiment, the driven holding means 17 is also provided with a clamping unit (not shown here) for clamping the drive pin. However, such a clamping unit can also be a functional part of the winder mandrel 9A or 9B.

  The non-driven holding means 18 includes another clamping unit so that the winder mandrel 9A or 9B can be temporarily fixed to the non-driven holding means 18 with reliability. Can be pinched.

  Since the respective drive train 17A or 17B of the respective winder mandrel drive 17C or 17D is at least partly arranged and formed in the rotor side part 6 or 7, the rotor side parts 6 and 7 Are each formed as a rectangular gearbox part 27 (referenced only by way of example), in which a holding means 17 which is driven in particular by a winder mandrel driving device is arranged.

  However, not only the holding means 17 and 18 are arranged in the gear box part 27, but also the external tooth ring 28 of the rotor drive device 29 for the rotor winder 4 is provided on the gear box part 27 or on the respective rotor side. It is fixedly connected to the side parts 6 and 7.

  The rotor drive 29 is here a component of the drive unit 30 common to the two rotor side parts 6 and 7.

  The drive unit 30 includes a transfer box having two transfer shafts. The transfer shafts are respectively engaged with pinion ring elements via pinion joints, and the rotor winder 4 is driven by the rotor drive device 29 in each of the pinion ring elements. In order to be able to be rotated about the rotor shaft 5, it interacts with an external tooth ring 28 fixed to the rotor side piece 6 or 7, respectively.

  Especially for gear unit parts (not shown) located and rotating in the gear box part 27 of the rotor side parts 6 and 7 of the respective drive train 17A or 17B of the respective winder mandrel drive 17C or 17D The rotor winder 4 is only provided with two more rotary oil discharge devices 38 so that the excess lubricant can be discharged again structurally easily. In the example, it is advantageously fluidly coupled to the gearbox portion 27 by only four oil discharge lines 39 (only labeled exemplary). A corresponding rotary oil supply device is arranged at the center in the region of the common rotor shaft 5, but this rotary oil supply device is not shown here.

  Furthermore, the device 1 has a delivery device 40 as an important functional component, by which the winder mandrel 9A or 9B is supported while the delivery device 40 is rotatably supported with the rotor winder 4. In addition, it can move independently of the rotation of the rotor winder 4. This significantly improves the effectiveness achievable with the device 1.

  The delivery device 40 has two oscillating parts 43 and 44, which in this embodiment rotate about the pivot axis 41, which is equal to the rotor axis 5, so that the apparatus 1 In spite of being the delivery device 40, it is functionally very compact.

  By means of two oscillating parts 43 and 44, each winder mandrel 9A or 9B is reliably supported by the delivery device 40 and is handed over or attached to the rotor winder 4 in the axial direction 8 or taken up by the rotor winder or Can be removed. In this case, each of the swinging parts 43 and 44 turns around the turning shaft 41.

  The first swing part 43 is arranged on the left side in the axial direction of the rotor winder 4, and is therefore the left swing part 43 of the device 1.

  Accordingly, the second oscillating component is arranged right next to the rotor winder 4 in the axial direction, and is therefore the right oscillating component 44 of the device 1.

  In this case, the left swing component 43 is pivotally driven by the left swing drive unit 45 (see FIG. 2). The right swing component 44 is swiveled by a right swing drive unit 46 (see FIG. 2) without depending on the left swing component.

  Both oscillating parts 43 and 44 each have an axial movement device 47 (which is only exemplary coded) having a guide track 48 and a carriage part 49 that can be translated along the guide track. Have.

  Since the carriage part 49 has a respective winder mandrel 9A or 9B, each winder mandrel 9A or 9B can move in the axial direction 8 of the rotor shaft 5, and each winder mandrel 9A or 9B has its carriage attached thereto. It is fixedly connected to the part 49. In that respect, each winder mandrel 9A or 9B is permanently connected to the associated oscillating component 43 or 44 at all times, i.e. especially during each process step.

  It can be seen that the cooperation between the guide track 48 and the carriage part 49 can be formed to be structurally different. In this embodiment, a carriage component movement drive device not shown here is disposed in the carriage component housing 50.

  In the carriage part housing 50, an expansion mechanism 51 for expanding the outer surface area of each winder mandrel 9A or 9B in the radial direction or correcting the previously expanded outer surface area is also structurally compact. Is housed in.

  Each of the swing parts 43 or 44 is supported in a swing part holding portion 52 (see also FIG. 2) so as to be able to turn around the rotor shaft 5 or the same turning shaft 41 as the rotor shaft 5.

  With the device 1 shown in FIGS. 1 and 2, the following first functional scheme, which is described by way of example, is possible.

  As shown in FIG. 1, the second winder mandrel 9B is already present at the winding start position 11, and the coil 3 has already been wound around the second winder mandrel. In advance, the right swing component 44 was swung upward so that the second winder mandrel 9B was arranged right next to the winding start position 11 in the axial direction. Next, the second winder mandrel 9B was inserted into the rotor winder 4 in the axial direction 8 by the axial movement device 47 and operatively coupled to both the rotor side parts 6 and 7. For this reason, the carriage component 49 is moved in the direction of the rotor winder 4 along the guide track 48 by the carriage movement drive device. In this case, the first end 15 on the drive side of the second winder mandrel 9B is introduced into the receiving element 25 of the holding means 17 to be driven on one side of the winder mandrel holding part at the winding start position 11, and therefore Then, it fixed to the 1st rotor side part 6 with the corresponding clamp unit. The undriven second end 16 of the second winder mandrel 9B, ie, an expansion for radially expanding the outer surface area of the second winder mandrel 9B or for correcting a pre-expanded outer surface area. The end with the opening mechanism 51 is fixed to the second rotor side piece 7.

  To start winding the coil 3, the motor of the first winder mandrel drive 17C (see FIG. 2) winds the receiving element 25 and thus also the winding via the gearbox part 27 of the first rotor side piece 6. The second winder mandrel 9B held at the start position 11 is driven.

  After pulling back the belt wrapper (not shown) from the winding start position 11 and / or after winding about 3 turns of the strip material 2, the winder tension applied to the strip material 2 is increased to the calculated required strength. The After several windings (or after release by the belt wrapper), the winding of the coil 3 that has begun to be wound is then rotated by rotating the rotor winder 4 about the rotor shaft 5 by 180 ° under sufficient strip tension. Repositioning to the winding position 12 is performed. Now, the second winder mandrel 9B previously illustrated at the winding start position 11 is present at the winding position 12 in the same manner as implied by the illustration according to FIG. 2 with respect to the first winder mandrel 9A. In this case, i.e. during the rotation of the rotor winder 4, the strip material 2 is further wound up with sufficient strip tension.

  That is, for this reason, the second winder mandrel 9B, the right swinging part 44, and the two rotor side parts 6 and 7 rotate around the rotor shaft 5 in synchronization.

  The second winder mandrel 9B whose coil diameter continuously increases is present at the winding position 12 (not shown, but see FIG. 2).

  On the other hand, as shown in FIG. 1, the first winder mandrel 9A is supported by the left swinging element 43 and is still in the standby position on the left side in the axial direction of the rotor winder. The first winder mandrel 9 </ b> A disposed on the left swing component 43 starts from the standby position and is disposed on the left side in the axial direction of the winding start position 11 later. Then, this first winder mandrel 9A is moved into the rolling line by the axial movement device 47 to the winding start position 11 in another step (similar to that already described in relation to the second winder mandrel 9B in advance). Ii) can be combined with the driven holding means 17 of the second rotor side piece 7. In this case, the undriven end of the first winder mandrel 9A exists so as to be supported and held in the undriven holding means 18 in the first rotor side piece 6.

  While the coil 3 is finished winding at the winding position 12 (not shown, refer to FIG. 2), at the winding start position 11, the first winder mandrel 9A waits for the start of the next winding start process.

  The strip end of the coil 3 is pressed against the coil that has been wound with the assistance of the pressing roller 60 in order to prevent the coil 3 from jumping up.

  When the coil 3 existing at the winding position is finished, the first or second winder mandrel 9A or 9B is reduced by the expansion mechanism 51, and then the first or second winder mandrel 9A or 9B coil 3 It is pulled out from the eye, that is, from the rolling line toward the right in the axial direction. At the end of this process, this first winder mandrel 9A is again completely located on its left swing part 43, or the second winder mandrel 9B is again completely right in its right swing part. 44 and is ready to be swung again next to the winding start position 11.

  In the case of the first functional scheme described above by way of example, the sleeve handling system has been omitted, however, the device 1 can also further comprise a sleeve handling system not shown here, thereby The functional scheme described below by way of example can be realized.

  When the strip material 2 starts to be wound around the coil 3, for example in a sleeve not shown here, provision is made for the corresponding sleeve handling when pivoting one of the rocking parts 43 or 44 in the form of another intermediate or standby position It is necessary to consider the position. For this reason, the winder mandrel 9A or 9B has the swinging part 43 or 44 after the winder mandrel is pulled out from the eye of the wound coil 3 by the attached axial movement device 47 at the end of the winding process. To turn to the standby position. Preferably in the rolling line, the empty sleeve already awaits taking over by the respective winder mandrel 9A or 9B. The sleeve is attached to the winder mandrel 9A or 9B by a sleeve handling system. This is already done for the purpose of the new coil 3 being started at the winding start position 11. After the sleeve has been secured to the winder mandrel 9A or 9B, the corresponding oscillating part 43 or 44 is then moved into the rolling line for starting winding and the axial movement device 47 of the corresponding rotor side part 6 or 7. The winder mandrel 9A or 9B and the sleeve attached to the winder mandrel are turned to the winding start position 11 so as to be inserted into the winder mandrel holding part opposite to the winder mandrel. Thereafter, a new winding start can be performed.

  According to the illustration according to FIG. 2, the device 1 is shown by way of example in a separate working phase, in which the first winder mandrel 9A is axially left from the eye of the coil 3 that has been wound. The second winder mandrel 9B is already in the winding start position 11. In this case, the right swing component 44 is turned with its guide track 48 facing upward, and the left swing component 43 is swung with its guide track 48 facing downward.

  What is of great importance for the present invention is that both oscillating parts 43 and 44 are arranged on opposite end faces outside the rotor winder 4, so that these oscillating parts are in any position. Regardless of whether or not, the winding stage in the rotor winder 4 is not affected.

  In order to further clarify the cooperation of the individual device components, in addition to the possible functional schemes already described by way of example before, according to the following FIGS. It is specifically illustrated and described.

  According to the illustration according to FIG. 3, as an approach to the possible process progression in the apparatus 1 shown in FIGS. 1 and 2, the first winder mandrel 9 </ b> A is modeled first outside the rotor winder 4 together with the left swing part 43. A working situation is shown in which the rotor is turned in accordance with a directional arrow 61 to a position on the left side in the axial direction of one rotor side part 6 or the winding start position 11. This working situation corresponds to the start of the installation on the first strip when the strip is not yet in a continuous process. In that case, another subsequent strip is processed continuously. The second winder mandrel 9B is exemplarily located at the lower position outside the rotor winder 4 together with the right oscillating component 44 at the lower side of the second rotor side component 7 or the winding position 12 in the axial direction at the start of the facility. Exists. The second winder mandrel 9B is pulled out from the coil 3 which has already been wound, and this coil is carried out of the winding position 12 in a straight line. During the continuous process, the first and second rotor side parts 6, 7 oscillate together or in parallel, respectively.

  According to the illustration in FIG. 4, the left swing component 43 is swung to the upper position, and therefore the first winder mandrel 9 </ b> A exists directly to the left of the winding start position 11 in the axial direction. As can be appreciated, the first winder mandrel 9A has a shaft of the left swinging part 43 until the first winder mandrel 9A is between the rotor side parts 6 and 7 (see FIG. 5). It is moved to the winding start position 11 in the axial direction 8 by the direction moving device 47. The second winder mandrel 9B is still in the lower position adjacent to the right of the winding position together with the right swinging component 44.

  According to the illustration according to FIG. 5, the first winder mandrel 9A is operatively coupled to the holding means 17 to be driven of the second rotor side part 7 at its drive end. The end of the strip material 2 supplied to the first winder mandrel 9A has already started to be wound around the first winder mandrel 9. The second winder mandrel 9B is still in the lower position adjacent to the right of the winding position together with the right swinging component 44.

  As shown in FIG. 6, the right swinging part 44 is swung out of the lower position together with the second winder mandrel 9B fixed to the right swinging part, and further upwards to the upper position. During the swiveling, the strip material 2 is further wound around the first winder mandrel 9A under sufficient winding tension.

  According to the illustration according to FIG. 7, all the pre-wrapped coils 3 which have been pre-filled in an exemplary manner are removed from the winding position 12 and the strip material 2 is in regular order the first winder during that time. Since the winding is started on the mandrel 9 </ b> A, the newly started coil 3 can move from the winding start position 11 to the winding position 12.

  For this reason, according to the illustration according to FIG. 8, the left oscillating part 43 starts to pivot with the rotor winder 4 out of the position above it according to the reverse arrow 62, so that the strip material 2 is further under sufficient winding tension. Is wound around the first winder mandrel 9A. That is, the rotor winder 4 is rotated from the winding start position 11 to the winding position 12 by 180 °. This gives good results. This is because the left swing component 43 is swung together with the first winder mandrel 9 </ b> A and the rotor winder 4 in the direction opposite to the strip travel direction of the strip material 2. This means that the first swing component 43 rotates from the upper position to the lower position in synchronization with the rotor winder 4. At the same time, until the right swinging component 44 exists on the right side in the axial direction of the winding start position 11 (see FIG. 9), it is swung in the direction of the upper position opposite to the rotor winder rotation direction. That is, the second swing component 44 rotates asynchronously with the rotor winder 4.

  As shown in FIG. 9, the second winder mandrel 9 </ b> B already exists on the right side in the axial direction of the winding start position 11. That is, while the first winder mandrel 9A is swung further downward by the left swinging component 43, the right swinging component 44 is swung to the upper position.

  According to the illustration in FIG. 10, since the left swing part 43 has arrived at the lower position, the first winder mandrel 9A is present at the winding position 12 and starts to wind around the first winder mandrel 9A. The wound coil 3 can finish winding at this winding position 12. In the meantime, the second winder mandrel 9B is moved to the winding start position 11 in the axial direction 8 by the axial movement device 47 of the right swing component 44, so that the coil 3 is further wound around the first winder mandrel 9A. While being finished, the second winder mandrel 9B is already ready for the beginning of the next volume.

  According to the illustration according to FIG. 11, the second winder mandrel 9 </ b> B is further moved in the axial direction 8 towards the driven holding means 17 present in the first rotor side part 6. At the same time, the strip material 2 is wound around the first winder mandrel 9A.

  As shown in FIG. 12, the coil 3 has been wound around the first winder mandrel 9A. Since the winding speed of the strip material 2 is reduced to the cutting speed and the separation is performed, the coil 3 is ready to be carried out in a straight line. Immediately after cutting, the strip material 2 can begin to wind around the second winder mandrel 9B positioned at the winding start position 11, which results in a winding process that is substantially uninterrupted.

  As shown in FIG. 13, the first winder mandrel 9 </ b> A is extracted from the coil 3 that has just been wound from the winding position 12 and positioned outside the rotor winder 4 to the left swing component 43. During this time, the coil 3 that is newly started to wind at the winding start position 11 is further started to be wound around the second winder mandrel 9B. The coil 3 that has already been wound at the winding position 12 is moved out of the winding position 12 in the carry-out direction 63 (otherwise it is oriented in the same manner as the strip supply direction).

  According to the illustration in FIG. 14, the left swing component 43 is swung out of the lower position and moved again to the upper position, so that the first winder mandrel 9 </ b> A is again in the axial direction of the winding start position 11. Located next to it.

  The process steps previously described according to FIGS. 3 to 13 may then be repeated with the winder mandrels 9A and 9B reversed.

  Optionally, an empty winder mandrel 9A or 9B may be further fitted with a sleeve element 64 on its respective path from the lower position to the upper position by means of a sleeve handling system not shown here.

  In this context, the features of the solution described explicitly or in the claims and / or the figures may be realized or achieved correspondingly cumulatively, so that the described features, effects and advantages can be realized accordingly. I would like to point out that it can be combined in some cases.

  It can be seen that the embodiments described above and in particular exemplary functional manners or process progressions are only a first form of the device 1 according to the invention for winding the strip material 2. In that respect, the form of the present invention is not limited to these examples.

  The device according to the invention can be used not only for winding the strip material around the coil, but also for unwinding the strip material from the coil. Unwinding is typically performed in a step sequence that is substantially the reverse of the coil winding described previously.
