Description

The invention relates to a decoiler and a decoiler method.

For example, it is from the DE 87 04 357 U1 known to unwind wires, in particular metallic wires, from coils, also called rings or coils, by applying a tension to a wire. It is evident here that the uncoiling devices and methods shown in this publication can only be suitable for very small and easily bendable wires, since the structural implementation is relatively filigree.

It is the object of the present invention to increase the operational reliability of an uncoiling device and an uncoiling method at a high operating speed.

The object of the invention is achieved by uncoiling devices and uncoiling methods with the features of the independent claims. Further advantageous refinements, possibly also independent thereof, can be found in the subclaims and the following description.

The invention is based on the basic idea that a multiple reel, in particular a double reel, is advantageous for reasons of operating speed, but that the reel crown from which unreeled should be stored as stable and separately as possible.

For example, a decoiler device for decoiling a ring of wire along a withdrawal direction with at least two reel crowns, which can each be brought into a withdrawal position and into a preparation and / or loading position via a displacement device, can be characterized in that the decoiler device has a safety device with an overload protection device and a safety guideway which has a directional component pointing in the withdrawal direction and is effective at least for the reel crown in the withdrawal position independently of the other reel crown, the overload protection device holding the reel crown in the withdrawal position in the withdrawal position and, in the event of an overload, the reel crown in the withdrawal position Releases the reel crown in the safety guideway in order to increase the operational safety of a decoiler and a decoiler at high working speed

When uncoiling a ring from an uncoiling device, various circumstances, for example due to the wire being knotted, can result in the wire not being able to be reeled out any further and the uncoiling device coming to a standstill. However, the wire continues to be drawn in by a subsequent machine, so that a very high force acts on the uncoiler, which suddenly stops. Here, the entire decoiler can be torn from its foundation by the suddenly occurring high forces. It goes without saying that this danger exists especially with stronger wires and correspondingly high machine outputs.

In order to increase the operational safety of a decoiler, a corresponding safety device with overload protection is used, so that in the event of a malfunction, for example caused by a knot in the wire, the decoiler is brought to a standstill so that possible damage and danger to body and machine are reduced , in particular, can be prevented. However, since on the one hand the decoiler cannot immediately come to a complete standstill when it is stopped and on the other hand very high forces act on it when the decoiler is stopped, even if the decoiler is stopped promptly or immediately, it could be torn out of its foundation and considerable Cause damage. The claimed safety guideway was used to provide the uncoiler with a safety path when stopping, along which it can move, so that time can be gained during the process along this safety guideway so that residual forces that arise when stopping can be absorbed or the uncoiler can move can still move in the direction of the forces acting in order to keep the forces acting on the uncoiling device as low as possible until the corresponding reel crown comes to a standstill.

It is advantageous if the safety guideway has a safety guiding axis. Such a safety guide axis is structurally simple to implement so that a corresponding guide can be made possible in the simplest possible way. In addition, such a safety guide axis can be made very stable, so that the reel crown can be guided in an operationally reliable manner.

It is advantageous if the overload safety device comprises a pressing device which, in the withdrawal position, presses a reel crown holder against a withdrawal position. By means of this pressing device, it can be achieved in the simplest possible manner and in a reliable manner that the reel crown holder is in the withdrawal position against a withdrawal position system is pressed, as a result of which it is achieved that in normal operation of the decoiler device this is set during decoiling so that in the event of an overload, the entire path of the safety guideway is available. Otherwise, due to the force acting purely on the uncoiling device as a result of the uncoiling, the uncoiling device could already be displaced in the direction of the uncoiling force as far as the stop of the safety guideway.

It is advantageous if the pressing device is designed to be hydraulic or pneumatic. This enables a relatively simple and operationally reliable control. In particular, the hydraulics or the pneumatics can have an overpressure valve which opens in the event of an overload. Hydraulically or pneumatically designed pressure devices can be implemented as simply as possible in order to be able to apply the required force. Understandably, it is also possible to design the pressing device differently, for example electrically. A pressure relief valve is advantageously also provided for the pressure device so that it can open in the event of an overload, so that possible damage in the event of an overload can be prevented. In particular, the pressure relief valve can be used as an overload safety device, which is structurally simple to implement.

Furthermore, the safety device can comprise a safety sensor which detects when the reel crown holder leaves the withdrawal position system and is operatively connected to a pulling device acting on the uncoiling wire in such a way that it stops when the reel crown holder leaves the withdrawal position system. This safety sensor makes it possible to ensure that no further wire or as little further wire as possible is unwound from the uncoiler device when the reel crown holder leaves the withdrawal position system. As a result, the process reliability is increased in a structurally simple way, because in the event of such an incident, possible dangers are further prevented by the fact that no additional wire is unwound.

An uncoiling device for uncoiling a ring made of wire along a pulling direction with at least two reel crowns, each of which can be brought into a pulling position and a preparation and / or loading position via a displacement device, can also be characterized in that the displacement device has an above-ground drive and / or a Has above floor guide or above floor storage in order to increase the operational safety of a decoiler device and a decoiler method at high working speed The operational reliability of the uncoiling device can be increased, since the elements are each arranged above the floor and in the event of an overload represent the lowest possible risk to the surrounding area. In addition, possible maintenance work can be simplified considerably because it is easier to achieve.

The displacement device preferably comprises a displaceable rotating body for holding at least one of the two reel crowns. Such a displaceable rotating body can form a rotatable displacement device rotatable with the simplest possible implementation and at the same time guaranteed high stability.

It is advantageous if the rotating body is driven via the above-floor drive and / or guided via the above-floor guide or supported by means of the above-floor bearing. Such an arrangement enables a structurally simple implementation as possible with high stability at the same time, since several separate bearings or guides are not required, but the rotating body can be directly connected to the drive or to the guide or the bearing.

In order to also achieve a structurally simple implementation with high stability, it is advantageous to design the rotating body so that it can only be displaced in one plane, preferably only horizontally.

Furthermore, the rotating body can have an axis of rotation and the safety guide axis can not be arranged identically, preferably genuinely parallel, to the axis of rotation. Due to the preferably genuinely parallel arrangement of the safety guide axis to the axis of rotation, a high level of stability can be achieved with the simplest possible design, the separation of the two axes being implemented in a structurally simple manner, in particular in contrast to axes lying one above the other.

Alternatively, the rotating body has an axis of rotation and the safety guide axis corresponds to the axis of rotation. Such an arrangement has the advantage that as few components as possible are used, which sometimes increases the operational reliability of the rotating body, but then there are constructive coordination tasks in order to separate the movements in the event of an overload from the movements that occur in the normal process.

The construction of the decoiler can also be further simplified if both reel crowns are mounted on the rotating body. Especially Both reel crowns can then be displaced simultaneously with a common drive if this is suitably connected to the rotating body, so that the transfer of the reels between different positions, such as a withdrawal position, a preparation position or a loading position, can be synchronized quickly and reliably.

Furthermore, a decoiler device for decoiling a ring made of wire along a pulling direction with at least two reel crowns, which can each be brought into a pulling position and in a preparation and / or loading position via a displacement device, can be characterized in that a rotating body is provided for each reel crown in order to increase the operational safety of a decoiler and a decoiler at high working speed. The fact that a rotating body is provided for each reel crown enables both reel crowns to be rotated or positioned, in particular independently of one another. This means that while one reel crown is being unwound, the other reel crown can be brought into position for loading. This minimizes the dead times that would arise when providing new wire. This advantage can possibly be accepted due to the disadvantage of a somewhat more complex drive.

It can be advantageous if the rotating bodies have an identical axis of rotation, as a result of which fewer components are required overall, which for example also reduces the costs of the device and also increases the operational reliability of the device.

A decoiler device for decoiling a ring of wire along a pulling direction with at least two reel crowns, which can each be brought into a pulling position and into a preparation and / or loading position via a displacement device, can be characterized in that the displacement device has a displaceable, tilting device supporting rotating body for holding at least one of the two reel crowns and by the tilting device the reel crown can be tilted between the preparation position and the loading position in order to increase the operational safety of an uncoiling device and an uncoiling process at high working speeds.

This design makes it possible to adjust the reel crowns according to their assigned work steps by means of a construction that is as simple as possible. While one reel crown is standing vertically and is being unwound, the other reel crown can be tilted into the preparation position and during unwinding of the first reel crown, the second reel crown can be prepared or loaded. This enables the most efficient possible loading and / or uncoiling process. Since set-up times or dead times are minimized as far as possible, they are even completely eliminated.

The tilting device preferably comprises a lever, on one arm of which the reel crown is arranged and on the other arm of which a tilting joint is arranged. This embodiment is particularly easy to implement in terms of construction and is extremely stable. The latter applies in particular when the lever is held on the rotating body via the tilt joint.

For a structurally simple implementation, it is also advantageous if the arm on which the reel crown is arranged is connected to the other arm via an overload joint. In this way, if necessary, the overload protection explained at the beginning can be provided in a structurally simple manner, with the overload case then also being able to be recorded relatively easily by measurement, namely precisely when the overload joint starts due to an overload.

The tilting device advantageously has a tilting axis which lies at the level of the reel crown and preferably intersects it. This has the advantage that the torques which have to be applied by the tilting device can be reduced, which is particularly true when the tilting axis intersects the reel crown.

An uncoiling device for uncoiling a ring made of wire along a pulling direction with at least two reel crowns, each of which can be moved into a pulling position and into a preparation and / or loading position, can also be characterized in that in the pulling position at least in the area of the pulling off Wire and / or at least in the area of the reel crown located in the withdrawal position or its reel mandrel to the reel crown not in the withdrawal position, a baffle wall is provided in order to increase the operational safety of a decoiler and a decoiler at high working speed. The baffle ensures that the unreeling process is reliable because the two reel crowns are shielded from one another or protected from one another.

The baffle wall is advantageously arranged on the rotating body because such an arrangement is particularly easy to implement in terms of construction and the baffle wall can be fastened in a sufficiently stable manner.

Likewise, a decoiling process for a ring made of wire, in which the wire is pulled by a pull acting on the wire in a pulling direction, can also be used Reel crown is withdrawn, characterized in that, in the event of an overload, the reel crown is released in the withdrawal direction and the pull is terminated in order to increase the operational safety of a decoiler and a decoiler at high working speed. By releasing in the pull-off direction, it is possible to prevent an overload from tearing the entire reel crown out of its fastening, in particular if a pull continues to act on the reel crown. At the same time the train is stopped so that the forces still acting on the reel crown can be limited to a minimum.

It is advantageous if the reel crown is released in a guided manner with a directional component pointing in the removal direction, so that the reel crown can be released as reliably as possible.

In addition, the decoiler can be designed as a double reel. Such a double reel enables the simplest possible structural implementation of the decoiler.

It goes without saying that the features of the solutions described above or in the claims can optionally also be combined in order to be able to implement the advantages cumulatively.

The Figures 1 and 2 show an uncoiling device 10 in which two reel mandrels 35 are arranged on a respective reel crown 30, one of the two reel mandrels 35 being in the withdrawal position 31 and the second of the two reel mandrels 35 being in the preparation or loading position 32, 33, with the second of the two reel mandrels 35 in the illustration after Figure 1 cannot be seen.

In the case of a wire 22 under tension 18, which is located as a ring 20 on the reel crown 30, the uncoiling device 10 can enable the wire 22 to be pulled off in the pulling direction 23 in a manner known per se. The wire 22 and ring 20 are in the Figures 1 to 3 not shown, but in the Figures 4 to 7 are shown schematically.

The uncoiling device 10 comprises a rotating body 42 which is mounted on the floor 12 so as to be displaceable about an axis of rotation 43.

A displacement device 40 serves to displace the reel mandrels 35 between the withdrawal position 31 and the preparation position 32 or loading position 33. The displacement device 40 comprises an above-ground drive 45, which is formed from a drive pinion 48 and a stationary gear 49, as well as an above-ground guide 46 along which the rotating body 42 is rotated about an axis of rotation 43 when moving via an above-ground bearing 47. The displacement device 40 is connected to the floor 12 by means of a floor anchor 16.

A horizontal 14 direction, correspondingly parallel to the floor, can also be defined by the floor 12.

Furthermore, the uncoiling device 10 comprises a safety device 50. This is intended to ensure an operationally reliable process in the event of an overload. In the event of an overload, a reel crown holder 38, which grips the reel crown 30, is displaced along the pulling direction 23 in the direction of the pull 18 via an overload joint 53 serving as an overload safety device 52, this displacement being guided by a safety guide track 54 and around a safety guide axis 56.

In the case of a normal state, when there is no overload, the reel mandrel 35 is held in its withdrawal position 31 by means of a pressure device 57 which comprises hydraulic cylinders 59 which move the reel mandrel 35 into position against a withdrawal position system 58, see FIG Figure 3 , press or hold down so that the Forces arising from the removal process result in a movement of the reel mandrel 35 along the safety guideway 54.

Furthermore, the decoiler device 10 comprises a tilting device 60, which comprises a lever 62, arms 63, 64 as well as a tilting joint 65 and a tilting axis 66. By means of this tilting device 60, the reel mandrels 35 can be tilted in order, for example, to tilt the one reel mandrel 35 in the preparation or loading position 32, 33 into a horizontal position and to erect it again accordingly.

In addition, two baffle walls 70 are arranged between the two reel mandrels 35 by means of baffle wall holders 71. The baffle walls 70 ensure an operationally reliable process, particularly with regard to the second reel mandrel 35, if an overload occurs in a first reel mandrel 35. The baffle wall 70 prevents, for example, a deflecting wire 22 from getting into the direct working area of the second reel mandrel 35. This means that both loading and preparation can be carried out independently of pulling off and in a reliable manner.

The Figures 2 and 3 show the embodiment according to Figure 1 in a side view, with the Figure 2 the reel mandrel 35 located in the withdrawal position 31 is in the normal state and the wire 22 is withdrawn via a pull 18 along the withdrawal direction 23. In the Figure 3 on the other hand, the corresponding reel mandrel 35 is in the overloaded state, this being displaced along the directional component 55 and along the safety guideway 54 by means of an overload joint 53 about the safety guiding axis 56. To this extent, in this exemplary embodiment, the safety guideway 54 is oriented in a circle around the safety guiding axis 56. In different embodiments, however, a straight safety guideway is also conceivable in that, for example, a slide is provided such that it can be displaced along a corresponding linear guide. It goes without saying that the safety guideway, depending on the specific requirements, can also be designed to be even more complex, for example elliptical.

The Figures 2 and 3 It can be seen that in this exemplary embodiment the reel mandrel 35 is in the withdrawal position 31 in a position which is not completely shielded by the baffle 70, which is arranged on the withdrawal position side, from the reel mandrel 35 in the loading or preparation position 32, 33 So that in this exemplary embodiment the second baffle wall 70 on the loading position side is additionally provided in order to also completely protect the second reel mandrel in its loading position 33 and the space in its vicinity with respect to the first reel mandrel 35 in the withdrawal position 31.

However, it is also conceivable to make one of the two baffle walls 70 displaceable in order to move the baffle walls 70 accordingly when the reel mandrels 35 are displaced, so that the reel mandrels 35 can be relocated without collision and in an operationally safe manner. However, repositioning of the baffle walls 70 may not be necessary if these two baffle walls complement each other in a suitable manner to form a common baffle wall or if it is possible to position a baffle wall in a correspondingly protective manner.

The embodiment according to Figure 4 provides a round rotating body 42 as the displacement device 40, which at the same time forms the safety device 50.

The reel mandrels 35 are each arranged on reel crowns 30 and connected to an above-ground guide 46 located radially on the outside of the rotating body 42. The reel mandrels 35 can be displaced radially around the above-ground bearing 47 via this above-ground guide 46.

It is also conceivable that the reel mandrels are also connected to an underfloor guide, which is located, for example, radially outside on the rotating body 42, possibly also while retaining the other features of the exemplary embodiments.

The drive for moving the reel mandrels 35 is designed as an above-ground drive 45. The overload protection device 52 of the safety device 50 comprises a safety guideway 54 which is arranged radially on the outside of the rotating body 42. A baffle wall 70 is attached to the rotating body 42 by means of a baffle wall bracket 71 and spatially separates the two reel mandrels 35 from one another.

The Figures 5 and 6 show the decoiler according to Figure 4 being in the Figure 5 the reel mandrel 35 is in the normal state in the withdrawal position 31, whereas the reel mandrel 35 in the withdrawal position 31 is in the overloaded state. In the embodiment according to Figure 6 an overload has occurred, as a result of which the reel mandrel 35 has shifted in the withdrawal position 31 along the directional component 55.

In detail, the in Figures 1 to 3 The technical details shown in the exemplary embodiment are also used accordingly in this exemplary embodiment.

The Figure 7 shows a decoiler according to Figure 6 , the reel mandrel 35 being in the preparation or loading position 32, 33 and being tilted about a tilting joint 61 by means of the tilting device 60 and, for example, for loading provided. It goes without saying that loading can also be possible when the reel mandrel 35 is upright.

In all the exemplary embodiments, a displacement device 40 enables the reel mandrel 35, which is upright and loaded again after loading, to be displaced via a rotary movement around the above-ground bearing 47 to the preparation position 32.

In the preparation position 32, numerous work steps can take place, which enable an operationally reliable sequence for the further process steps. For example, very thick wires 22 can be used. It goes without saying that wires with a large diameter are significantly more difficult to handle than thinner wires 22. Thus, the wire 22 can be made available in the preparation position 32 by, for example, unrolling it from the reel mandrel 35 a certain length. As a result, the wire 22 can be introduced into a drawing machine or incorporated into the subsequent processes much more easily.

It is also possible, depending on the thickness of the wire 22, that the end of the wire cannot be fed directly into the following machines, for example a drawing machine, if the diameter of the wire 22 is too large. For example, in the preparation position 32, the ends of the wire 22 can be processed. For example, at least a portion of the wire 22 can be reduced in diameter. In order to make the end of the wire 22 grippable for subsequent machines, it is also conceivable to prepare the wire 22 in the preparation position 32, for example by notches, in such a way that a corresponding gripping device grips the wire 22 in an operationally reliable manner and the following machine, preferably a drawing machine, can feed.

The prepared and loaded reel mandrel 35 can then be brought into the withdrawal position 31 by means of the displacement device 40. In this pull-off position 31, the wire 22 is also pulled off in the pull-off direction 23.

The pull-off position 31 comprises a safety device 50, which consists of an overload protection 52 and a pressing device 57. In the event of an overload, which can arise from all possible disturbances, such as a knot in the wire 22 or the like, the reel mandrel 35 can still move along the safety guideway 54, so that the reel mandrel 35 will still move in the event of a failure of the system or an overload can move along a defined distance so that the system comes to a standstill in an operationally safe manner.

An overload is often accompanied by a rapid standstill of the system, so that hardly any further wire 22 is unwound along the pulling direction 23.

The overload protection 52, however, gives the system some time to come to a standstill in an operationally reliable manner, so that the reel mandrel 35, for example, is not torn from its foundation or from the floor 12 and thus represents a danger to the environment. In the normal withdrawal state, the reel mandrel 35 is held in the withdrawal position 31, for example by means of a hydraulic cylinder 59, so that the forces introduced by the withdrawal do not already cause the reel mandrel 35 to shift along the safety guideway 54.
