Definitions

  • the invention relates to a device for screwing Fastening elements for fastening insulation material on flat and shed roofs
  • Such a screwing device is from the German Publication DE 42 40 607 A1 known.
  • This known device has a feed device for the fasteners, one lowerable screw unit and a holding device for the Fastening element, which takes this up before screwing it in and then releases.
  • Pre-assembled, two-part fastening elements in particular from holding part and screw existing, processed by a separating device in the magazine to separate one fastener from the fastener chain intervenes. After separation, the fastener becomes one Holding device supplied, in which it is captured by a screw unit and in the roof surface is driven. The isolation is due to the Aufund Downward movement of the screw unit from a locked position into one Release position offset.
  • the known device is complex, complicated and prone to failure, which is why rapid screwing is not possible.
  • the transfer of a fastening element isolated from the magazine or from the other fastening means into the screwing position is not possible without problems.
  • the screw tip of the screw rod cannot engage in the fastener or immerse it properly.
  • a device with an equivalent separation as is known from DE 42 40 607 A1, is described in European Patent EP 0 600 285 B1, in which, however, the holding device comprises a clamping device which is formed from support elements which are arranged in a horizontal Perform a closing and opening movement on the level.
  • the fastening element is enclosed in the shaft area. Only after the screw of the fastener has cut into the roof surface, the supports release the fastener.
  • the opening movement is caused by a movable angle with wedge surfaces.
  • the fastener can be used tilt into a vertical position due to its heavier tip and are therefore not caught by the screw tip.
  • Another disadvantage of the known devices is their relative Immobility. By arranging the magazine, the screw unit and their lowering aids, the separation and the feeding devices these devices are not only heavy but also have one unfavorable size.
  • the screw axis is relatively far from Device edge, so that work on the attic of the roof or in the Area of skylights with the known devices not possible at all are and must be worked by hand at these points.
  • the present device is said to be considerably simpler built and improved device are provided that are not compatible with the Problems of the known devices is afflicted.
  • the invention enables the fastener to be inclined Roof surfaces can be processed. Even if the device according to the invention in is in an oblique position, the fastener is coaxial with Screw rod and thus aligned with the screw axis. Thereby, that is activated by the lifting movement of the screwing unit Holding device also a clamp on the recorded Fastener exercises, the device can also on the other poorly accessible roof areas can be used without it Function would be restricted in any way. Even on inclined ones The fastening element becomes roof surfaces exactly in the screw-in axis aligned for installation.
  • the proposed row-shaped structure of the device allows a slim design, so that the device on almost all Roof stations is operational.
  • This advantage is particularly due to this reached because the screw axis of the device is relative due to this small size is near the edge of the device and thus also Machined roof edge areas or edge zones in the area of skylights can be.
  • the device according to the invention i.a. oval, round and collated plastic screw combinations can be processed.
  • the invention provides that a pliers-shaped in the holding device Gripper is arranged, the gripper movement by the lifting movement the tightening unit is triggered. Due to the ability of the holding device can exert a pliers movement on the fastener e.g. the phases of the clamping and release situations are individually manipulated become.

Even if the selected gripper shape for a certain type of fastener would not be suitable, the gripper can against an individually adapted Grippers can be replaced quickly and easily.
  • a very special advantage is that the fork arms close the shaft of the Fastening element through a transverse to its longitudinal axis Include aligned pliers movement. This can be aligned that the gripper arms are not within the magazine's ejection path or the feed device. Thus, the holding device also carries contributes significantly to the narrow construction achieved. According to the invention also provided that each fork arm in a vertical plane aligned tax courage is led. This in turn means for the Size of the device that no adjusting or control means in the Swing out the horizontal and thus have no influence on the width of the device to have. According to the number of fork arms are on both sides of the Screw-in axis provided such control grooves. Thus, the Fork arms can be controlled independently but also synchronously.
  • each fork arm is parallel to its own one Longitudinal axis offset axis pivotable.
  • the Fork arms carry the fastener sufficiently long and only then be swiveled out of the screw-in axis, e.g. if the Screw tip or a guide grommet secure the fastener has detected so that the fastening element breaks out of the Screw-in axis is no longer possible.
  • control grooves both in the area of top dead center as well as in the area of the bottom dead center from the screw-in axis lead away. This ensures that the holding device is first closes during the downward movement of the screwing unit, i.e. the Pliers movement only after a specified path of the screwing unit is activated and thus on the feeder and separation can be coordinated. This can be done by the magazine or the feeder Separating device coming fastener in a relative wide open holding device that can be thrown in screw-in closes, the fastening element is fixed and closed releases at a given time.
  • the fork arms are expediently at one with their pivot axes Arranged vertically movable centering block along the screw-in axis. This ensures a synchronous process with this, especially since Centering block at the free end of the screw rod of the screw unit surrounding lifting sleeve is arranged. This also ensures that possible lifting delays on the lifting sleeve not on the holding device can be transferred, the tax history through the Tightening unit activated indirectly but not directly manipulated.
