Definitions

  • the invention relates to a winding machine for unwinding strip-shaped material from at least one spool according to the preamble of claim 1 and a dancer arm according to the preamble of claim 9.
  • Plug contacts for the automotive industry can be made from the strip-shaped material.
  • the material can be unwound from a spool rotating about a horizontal axis as a drum. Above a certain size, however, such coils become so heavy that horizontal storage of the coils is preferred.
  • the processing machine is assigned so-called horizontal unwinders, which enable the strip-shaped material to be unwound from the coils that are lying, that is, rotating about a vertical axis.
  • Such a horizontal unwinder which is based on the preamble of claim 1 or 12, is from DE 202 03 476 U1 known.
  • the material is unwound from the spool, deflected around a deflection element on a dancer arm and then transferred to a belt take-off.
  • a sensor device is arranged downstream of the strip pull-off, which scans the loop of material present between the processing machine and the unwinder and, depending on the position, gives the strip pull-off and the rotary drive for the rotation of the coils a corresponding signal for further advance and thus for unwinding the material.
  • the deflection element is arranged on a dancer arm which, under load, is held in its position in a controlled or regulated manner by an elastic element. This keeps the material under tension. If the belt draw-off requests more material, the rotary drive is switched on as soon as the deflection element has passed a certain position.
  • the DE 27 44 801 A1 shows an output device with a horizontal coil for unwinding strip material.
  • a gripping device for gripping a spool is known, with a dancer device being provided for the unwinding of strip material.
  • the DE 39 14 0564 A1 discloses a wire spool wire unwinding machine.
  • the object of the present invention is to create a winding machine for unwinding material in the form of strips or strips, with a dancer arm and a dancer arm that can also be used in a variety of ways when operating with bobbins whose axes of rotation have varying angular positions during unwinding exhibit.
  • a winding machine for unwinding material in the form of a strip or strip has at least one rotary drive for rotating the spool about an axis of rotation depending on the requirements of a downstream processing machine.
  • the material in strip form is fed to the processing machine via a guide device using an adjustable dancer arm.
  • a deflection element that deflects the material about a further axis of rotation is provided on the dancer arm.
  • the guide device has a belt take-off, which then makes the material available depending on the requirements of the processing machine.
  • the winding machine is set up to unwind coils whose respective axes of rotation have different angular positions ⁇ to the horizontal of 0° ⁇ 90° when unwinding.
  • the further axis of rotation of the deflection element on the dancer arm can be pivoted with respect to its angular position to the respective angular position of the axis of rotation of the coil and can also be fixed in this position.
  • the axis of rotation of the spool and the further axis of rotation of the deflection element are aligned essentially parallel to one another during unwinding, with slight angular deviations from the parallel in the range of up to 10°, preferably up to 5°, being necessary under certain circumstances in order to separate the material from gently and well guided from the bobbin over the dancer arm to the strip take-off.
  • Such an arrangement ensures reliable processing that is, above all, gentle on the material, especially in the case of sensitive parts.
  • the dancer arm preferably has an arm which is operatively connected to a holding element for the deflection element in an articulated and lockable manner.
  • the axis of rotation of the deflection element can preferably be transferred into an essentially horizontal position or an essentially vertical position. This ensures an arrangement of the axis of rotation of the deflection element which primarily corresponds to an arrangement of the coil if it has either a horizontal axis of rotation or a vertical axis of rotation. This ensures that the axes are parallel to each other and ensures reliable and material-friendly operation when unwinding the material.
  • the arm is also preferably arranged on the dancer arm in a longitudinally adjustable manner, as a result of which the distance between the deflection element and the central axis of the dancer arm can be adjusted.
  • corresponding release mechanisms can be provided in order to releasably fix the arm in its respective position. This enables an arrangement which ensures a suitable angle of enclosure of the deflection element and at the same time takes into account the maximum permissible deflection of the material.
  • the arm is preferably also adjustable transversely to its longitudinal direction and can be fixed in its respective position.
  • the pull-off angle can advantageously be adapted to the respective material.
  • the arm can preferably be mounted on a sliding element which can be displaced in a guide of a guide block extending transversely to the longitudinal extension of the arm.
  • the holding element can thus be fixed in almost any desired angular position, which can be adapted to the respective angular position of the spool or drum.
  • the holding element can be designed so that it can be latched to recesses in the arm via a spring latching device.
  • This has the advantage that predetermined locking positions for the holding element can be assumed in a technically simple manner, which are adapted to the usual position of the drum or spool.
  • a sleeve is preferably mounted on the elongate holding element so that it can be displaced against the force of an elastic element in the longitudinal direction of the holding element for the detachable operative connection with the recesses. Due to a technically reliable latching, which is nevertheless easily releasable, the holding element can advantageously be adjusted quickly with one hand movement.
  • the dancer arm can preferably be pivoted by at least 180° about its vertical central axis. This pivoting movement preferably takes place in such a way that the dancer arm pivots outwards as seen from the turntable for the bobbin.
  • the dancer arm can thus enable the deflection element to be arranged on both sides, which is particularly advantageous when it is necessary to switch between clockwise rotation and counterclockwise rotation when unwinding the bobbin.
  • the winding machine is set up both at least one coil arranged on a pallet in a pallet mode and thus around a vertical Unwind axis of rotation and designed as a drum coil in a drum mode and thus unwind around a horizontal axis of rotation. Since these are the arrangements that usually occur for the strip-shaped material to be unwound, these positions are preferably maintained and positioned, which enables versatile operation and reliable unwinding that is gentle on the material.
  • the invention is also achieved by a dancer arm for a winding machine for unwinding material about an axis of rotation, a deflection element deflecting the material about a further axis of rotation being articulated on the dancer arm.
  • the winding machine is set up to unwind coils with different angular positions
  • the other axis of rotation of the deflection element on the dancer arm is pivotable with regard to its angular position so that it can be adapted to the variable angular position of the axis of rotation of the coil and fixed in this position.
  • the dancer arm can be used in a variety of ways to unwind coils with a different arrangement of the axis of rotation, without a separate device being required for this.
  • a preferred operation is possible with a combi-unwinder, which enables the coil to be unwound around a horizontal axis as well as around a vertical axis, with all angular positions in between also being possible.
  • the dancer arm preferably has an arm which is operatively connected in an articulated and fixable manner to a holding element for the deflection element, with the further axis of rotation of the deflection element preferably being able to be converted into a substantially horizontal position or into a substantially vertical position.
  • Such a configuration of a dancer arm with such bevels enables an operator to position the axes of rotation without further ado. This ensures that the material is guided around the deflection element in a suitable manner and with a suitable angle of wrap. A material-friendly operation is thus guaranteed.
  • the arm is preferably arranged on the dancer arm in a longitudinally adjustable manner, with the distance from the deflection element to the central axis of the dancer arm being releasably adjusted by a longitudinal adjustment of the arm.
  • This can in terms of the feed angle of the band or strip-shaped material to the deflection element as well as the discharge angle from Deflection element optimization can be easily achieved by adjusting the distance accordingly.
  • the distance also has an influence on the tensile stress to which the material is subjected.
  • the arm of the dancer arm is preferably adjustable transversely to its longitudinal direction and can be fixed in its respective position.
  • the pull-off angle can advantageously be adapted to the respective material.
  • the arm can preferably be mounted on the dancer arm on a sliding element which can be displaced in a guide of a guide block extending transversely to the longitudinal extension of the arm.
  • the holding element can be fixed in almost any angular position that corresponds to the respective angular position of the coil or the drum is adjustable.
  • the holding element on the dancer arm can be designed so that it can be latched to recesses in the arm by means of a spring latching device.
  • This has the advantage that predetermined locking positions for the holding element can be assumed in a technically simple manner, which are adapted to the usual position of the drum or spool.
  • a sleeve is preferably mounted on the elongate holding element so that it can be displaced against the force of an elastic element in the longitudinal direction of the holding element for the detachable operative connection with the recesses. Due to a technically reliable latching, which is nevertheless easily releasable, the holding element can advantageously be adjusted quickly with one hand movement.
  • the dancer arm can be pivoted by at least 180° about its vertical central axis. This makes it possible to switch the coil from left-hand to right-hand rotation, depending on the arrangement of the coil on a winding machine.
  • the dancer arm can be sold and used separately from the winding machine.
  • the figures show a winding machine 10 for unwinding band or strip-shaped material 12 from at least one spool 20.
  • a rotary drive for conveying the band-shaped Material 12 is a rotary drive, not shown in the drawing, for turning a 2 recognizable turntable 16 used in 1 pivoted to an upright position. In this upright position, the rotary drive drives a drum 28 .
