Definitions

  • the invention relates to a device for straightening coil material wound into spools and for introducing the same into the feed of a further processing machine, consisting of an unwinder and a straightening unit arranged downstream thereof, which is equipped with lower and upper straightening rollers and, if appropriate, feed rollers.
  • This known device has the disadvantage that, on the one hand, a fixed transfer device is provided between the unwinder and the straightening unit and, on the other hand, a stationary lifting table is provided between the straightening unit and the downstream processing machine, which represents a comparatively large outlay, quite apart from the fact that this also results in optimal loop formation between the straightening unit and Feed of the processing machine is not possible.
  • the invention has for its object to provide a generic device while avoiding the aforementioned disadvantages, which not only an immediate tape start transfer "unwinding straightening unit", but also a tape start transfer "straightening unit feed” and beyond such a setting the distance between the straightening unit and the feed of the further processing machine enables an optimal loop formation to be guaranteed.
  • this is achieved in that the straightener can be moved between the unwinder and the feed of the further processing machine, preferably a press. Due to the movable training of the Straightening unit, the previously common transfer device and the lifting table are no longer in use, since the possibility of moving the straightening unit back and forth means that the beginning and transfer of the strip is carried out by the straightening unit itself and, moreover, the straightening unit can be moved into the intermediate position, which ensures optimal loop formation Band material results.
  • the unwinder and the straightener or the like are on a common platform. arranged. This platform is placed directly in front of the feed of the further processing machine, so that the tape start transfer into the feed of the same is possible without intermediate arrangement of special auxiliary units.
  • the straightener is attached to one or more guides - preferably in the manner of a suspension railway - so that there is a completely free space underneath the straightener over its entire travel range, which enables the setting of an optimal loop.
  • the guide or the guides can advantageously be raised and lowered at their end or ends on the unwinder side and at their further processing machine-side end or ends pivotally attached. This adjustability results in an optimal transfer position for the beginning of the tape of the spool on the unwinder.
  • the upper part of the straightener is suspended from the guide or guides, while the lower part contains the straightening rollers and, if applicable, the retracting rollers, or vice versa.
  • the upper part also carries the drive for moving the straightening unit.
  • the part of the straightening unit containing the straightening rollers and possibly the feed rollers is flanged to the part assigned to the guide or the guides so that a wide variety of straightening heads can be used.
  • the unwinding end of the guide or the unwinding end of the guides is or are articulated on the unwinder by means of at least one actuator.
  • the processing machine end of the guide or the processing machine ends of the guides is or are pivotally attached to one or more supports, so that when the actuator or actuators are actuated, the guide or guides pivots around the hori Execute the central axis on the support or supports.
  • the guide can be formed by an I-profile carrier which is equipped with a toothed rack which meshes with a drive pinion of the straightening unit.
  • a freely projecting pair of gripper jaws is provided on the unwinding unit, the angle of attack of the upper and / or lower gripper jaw being separately adjustable.
  • the pair of gripper jaws is used to grasp the start of the tape of the spool on the unwinder and the transfer to the straightening unit in cooperation with the drive of the unwinder.
  • pressing the pair of gripper jaws causes the beginning of the strip to be straightened before it is transferred to the straightening unit.
  • the straightener has a geared control motor, the speed of which is infinitely adjustable.
  • the straightener 6 is designed to be movable between the unwinder 1 and the conventional feed of a further processing machine, for example a press, which is not shown.
  • the straightening unit 6 is suspended from a guide 7, which is formed by an I-profile carrier.
  • the upper part 8 of the straightener 6 is suspended from the guide 7.
  • the actual straightening unit with straightening rollers and feed rollers is also conventional.
  • the guide 7 is designed to be raised and lowered at its unwind end 10 by means of an actuator 11, for example in the form of a cylinder-piston unit or a spindle drive, and articulated on the uncoiler 1.
  • the processing machine end 12 is attached to a support 13 in a bearing block 14 of the same about a horizontal axis.
  • the support 13 is also on platform 2.
  • the guide 7 is equipped with a rack which meshes with a drive pinion of the straightening unit 6, which is not shown for the sake of clarity.
  • the gripper jaws are opened and closed via actuators 16, e.g. in the form of cylinder-piston units, worm drives or the like.
  • the angle of attack of the upper and lower gripper jaws can be set separately.
  • the straightening unit 6 In the open position of the pair of gripper jaws 15, the straightening unit 6 is then moved to the end 12 of the guide 7 on the processing machine side, with simultaneous feed via the unwinder drive. As soon as the end 12 and thus the feed located behind it, for example a press, has been reached, the beginning of the tape is transferred to the feed of the downstream processing machine. As soon as the beginning of the strip has been inserted into it, the straightening mechanism 6 moves back into an intermediate position which, in accordance with the sheet thickness of the strip material to be straightened, results in optimal loop formation. Since the device according to the invention is completely free below the guide 7 and the straightening unit 6, the loop control unit can always be moved into the apex of the loop.
  • the straightening mechanism 6 is shifted by means of a geared control motor.
  • a frequency converter (sine modulated) is used to control the control motor.
  • the run-up, the run-down and the forward speed are infinitely variable, the motor with a spring pressure disc brake is provided.
  • the control bottle which hangs on a power supply rail at operating height, contains all the operating elements for the straightening unit 6 and the conveyor start conveyor.
  • Another control bottle which is located near the unwinder, contains the controls for the unwinder and the hydraulically operated pressure roller.
