Definitions

  • the invention relates to a decoiler and a decoiler method.
  • 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.
  • 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
  • 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.
  • 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.
  • the safety guideway has a safety guiding axis.
  • a safety guide axis is structurally simple to implement so that a corresponding guide can be made possible in the simplest possible way.
  • a safety guide axis can be made very stable, so that the reel crown can be guided in an operationally reliable manner.
  • the overload safety device comprises a pressing device which, in the withdrawal position, presses a reel crown holder against a withdrawal position.
  • 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.
  • the pressing device is designed to be hydraulic or pneumatic. This enables a relatively simple and operationally reliable control.
  • 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.
  • the pressure relief valve can be used as an overload safety device, which is structurally simple to implement.
  • 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.
  • 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.
  • 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.
  • a displaceable rotating body can form a rotatable displacement device rotatable with the simplest possible implementation and at the same time guaranteed high stability.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the arm on which the reel crown is arranged is connected to the other arm via an overload joint.
  • 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.
  • 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
  • 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.
  • the train is stopped so that the forces still acting on the reel crown can be limited to a minimum.
  • 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.
  • the decoiler can be designed as a double reel. Such a double reel enables the simplest possible structural implementation of the decoiler.
  • FIGS. 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.

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • FIGS. 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.

  • the safety guideway 54 is oriented in a circle around the safety guiding axis 56.
  • 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.

  • baffle walls 70 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.
  • 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.
