Definitions

  • the invention relates to a device for straightening strip material wound into spools and for introducing the same into the feed of a further processing machine according to the preamble of patent claim 1.
  • Such a device is known from DE-A-28 11 418, in which the straightening unit can be moved in the direction of the strip feed between the unwinder and the further processing machine.
  • the straightening unit has a carriage which can be moved back and forth on a guide device provided on a platform.
  • an insertion wedge is provided in the known device, by means of which it can be ensured that the beginning of the strip gets into the entrance area of the straightening unit.
  • the arrangement of the undercarriage and in particular the guide device below the straightening unit limits the space available for the adjustment of the belt loop in the case of the known device.
  • the insertion wedge can ensure that the strip start reaches the entrance area of the straightening unit, but it is not possible to adapt the straightening unit position to the design of the strip start.
  • the invention has for its object to further develop the generic device such that, on the one hand, an optimal adjustment of the straightening mechanism to the respective band start is possible and that, on the other hand, the space available for the band loop adjustment is increased.
  • the suspension of the straightening unit on one or more guides ensures that the space available underneath the straightening unit, which is required for belt loop adjustment, is as large as possible.
  • the pivotable design of the guide or the guides also ensures that the straightener can be positioned as such that the beginning of the tape can be optimally picked up by it.
  • the unwinder and the straightening unit are preferably arranged on a common platform or the like. This platform is placed immediately 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 the interposition of special auxiliary units.
  • the upper part of the straightener is suspended from the guide or guides, while the lower part contains the straightening rollers and, if necessary, the retracting rollers or vice versa.
  • the upper part also carries the drive for moving the straightener.
  • 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 pivotably attached to one or more supports, so that when the actuator or the actuators are actuated, the guide or guides pivots about the horizontal axis on the support or carry out the supports.
  • the guide can be formed by an I-profile carrier, which is equipped with a rack that meshes with a drive pinion of the straightening unit.
  • I-profile carrier which is equipped with a rack that 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 are.
  • 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 straightens the beginning of the belt before transferring it 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 beam.
  • the upper part 8 of the straightener 6 is suspended from the guide 7.
  • the straightening rolls are located in its lower part 9 as well as the feed rollers.
  • 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 is articulated on the uncoiler 1.
  • the further processing machine end 12 is attached to a support 13 in a bearing block 14 of the same pivotable about a horizontal axis.
  • the support 13 is also on the 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 operation of the device according to the invention is as follows: In the position of the straightening unit 6 shown in the figure, that is to say both with respect to the unwinder 1 and with regard to its height, there is an optimal takeover position for the beginning of the tape by the straightening unit 6, which is held down by the pressure roller 9 on the arm 17.
  • the beginning of the band is pushed between the open jaws of the pair of gripper jaws 15. Opening and closing them straightens the beginning of the tape.
  • the feed between the feed rollers that may be present or between the straightening rollers is then carried out via the drive of the unwinder 1.
  • 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 further 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 being equipped with a spring-loaded disc brake.
  • 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.
