Definitions

  • the invention relates to a device for screwing in fasteners, in particular for fastening insulating material on flat and shed roofs by means of screws which are loosely arranged in front of a magazine, each inserted in a plastic holder having a support plate or in a washer, with a lowerable screw
  • Screwing unit with a separating and feeding device for the fastening elements that can be activated by the lowerable screwing unit, and with a holding device in which the fastening elements in each case in front of the
  • Tightening screws are added and then released, the holding device being able to be guided from the top dead center to the bottom dead center by the lifting movement of the screw unit, according to the preamble of the main and secondary claims.
  • Screwing devices serve for the most efficient fastening of roof sealing and insulation material on flat and shed roofs and are offered in a wide variety of embodiments.
  • Such screwing devices are known from German laid-open specification DE 42 40 607 A1.
  • This known device has a feed device for the fastening elements, a lowerable screw unit and a holding device for the fastening element, which first picks it up before screwing it in and then releases it.
  • Pre-assembled, two-part fastening elements, in particular consisting of a holding part and a screw are processed in this device.
  • 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 Do not engage the screw rod in the fastener or immerse it properly.
  • Another disadvantage of the known devices is their relative immobility. Due to the arrangement of the magazine, the screwing unit and its lowering aids, the separation and the feeding devices, these devices are not only difficult but also have an unfavorable size.
  • the screw-in axis is located relatively far from the edge of the device, so that work on the attic of the roof or in the area of skylight domes is not possible with the known devices and must be done by hand at these points.
  • the present device is intended to provide a device which is of considerably simpler construction and improvement and which does not have the problems of the known devices.
  • the holding device clamps the fastening means between the bottom dead center and the top dead center, in accordance with the characterizing part of the main claim.
  • the holding device be arranged in a housing which forms the mounting surface of the device and on which the screwing unit with its lifting aids and guides are arranged in a row so as to rise in a row.
  • the device can also be used on the otherwise difficult to access roof locations without the function thereof being restricted in any way. Even on sloping roof surfaces, the fastener is aligned exactly in the screw-in axis for installation.
  • the proposed row-shaped structure of the device permits a narrow construction, so that the device can be used on almost all roof locations. This advantage is achieved in particular because the screw-in axis of the device is located near the edge of the device due to its relatively small size, and thus roof edge areas or edge zones in the area of skylights can also be processed.
  • oval, round and magazined plastic screw combinations can be processed.
  • a gripper-shaped gripper is arranged in the holding device, the gripper movement of which is triggered by the lifting movement of the screwing unit. Due to the ability of the holding device to exert a pliers movement on the fastening element, e.g. the phases of the clamping and release situations are individually manipulated.
  • the pincer-shaped gripper is formed by the shank of the fastening element between fork arms enclosing it, on which the washer or the distributor plate of the plastic holder rests.
  • a gripper is simple yet functional in construction. With such a gripper, a variety different fasteners are included. Even if the selected gripper shape would not be suitable for a certain type of fastening element, the gripper can be exchanged easily and quickly for an individually adapted gripper.
  • a very special advantage is that the fork arms enclose the shaft of the fastening element by means of a pincer movement oriented transversely to its longitudinal axis. This can be aligned in such a way that the gripper arms are not within the ejection path of the magazine or the feed device.
  • the holding device contributes significantly to the narrow design achieved.
  • Each fork arm is expediently pivotable about an axis which is offset parallel to its own longitudinal axis. This means that the fork arms can carry the fastening element for a sufficient length of time and can only be swiveled out of the screw-in axis when, e.g. the screw tip or a guide sleeve has securely gripped the fastening element, so that it is no longer possible for the fastening element to break out of the screw-in axis.
  • each fork arm is guided in a control groove aligned in a vertical plane.
  • this in turn means that no adjusting or control means swivel out horizontally and thus have no influence on the width of the device.
  • control grooves are provided on both sides of the screw-in axis. This means that the fork arms can be controlled independently but also synchronously.
  • the fastening element coming from the magazine or the feeding and separating device can be thrown into a relatively wide-open holding device which closes in a manner suitable for screwing in, fixes the fastening element and releases it at a given time.
  • the fork arms are expediently arranged with their pivot axes on a centering block which can be moved vertically along the screw-in axis. This ensures a synchronous process with this, especially since the centering block is arranged at the free end of a lifting sleeve surrounding the screw rod of the screw unit. This also ensures that any stroke delays on the lifting sleeve cannot be transmitted to the holding device, the control / operation of which is activated indirectly by the screwing unit but is not directly manipulated.
  • the centering block is penetrated by the screw rod to such an extent that the screw insert can grasp the screw of the fastening element in a functional manner.
  • a particularly preferred embodiment of the invention provides that the holding device is arranged within a housing that can be placed on the roof to be treated.
  • the moving parts of the holding device are thus delimited from the user, so that the risk of an accident is largely ruled out if the device is used properly.
  • the housing has the further advantage that it serves practically as an attachment element for the assembly point.
  • the housing is the widest part of the device protruding part and serves to align the device perpendicular to the roof surface and parallel to the roof edge, in particular to the parapet.
  • the housing is at least partially open on the housing side carrying the control grooves. This ensures the unimpeded feeding of the fastening means to the holding device.
  • the housing is also expediently at least partially open on the floor, so that no housing parts lying in the screw-in axis can interfere with the driving of the fastening elements into the roof substructure.
  • a particularly expedient embodiment of the invention provides that the magazine is rigid and is arranged on the at least partially open side of the housing with its ejection end, directed towards the holding device.
  • the magazine of the device according to the invention is more favorable in its presentation behavior. That the fastening elements located in the magazine are not exposed to any swiveling movements through the magazine and remain relatively evenly upstream in the magazine, which considerably facilitates the subsequent separation.
  • a particularly preferred embodiment of the invention provides that the singling and feeding device is arranged at the end of the magazine near the holding device and consists of a slide which can be moved linearly horizontally and transversely to the magazine and which has two pawls which, caused by the lifting movement of the screwing unit , engage in the stacking level of the magazine and present the fasteners, separate them and feed the fastener, which is separate from the magazine stream, to the holding device.
  • This is the simplest but most effective way of creating a separating device that works in a confined space.
  • the slide practically moves only on a path that is approximately the shaft diameter of the Fastener corresponds. Since here, too, no device parts swivel out horizontally, the action radius of the slide is limited to the housing width or its length, so that the narrow construction of the device is also preserved here.
  • the slide expediently carries a pin which is guided within a control bar which can be lowered vertically and linearly together with the screw unit. Due to the linear movement of the control bar, deviations of the slide movement are almost impossible.
  • the control bar is connected to the centering block and coupled directly to its lifting movement. Stroke delays of the screwdriver unit are therefore not transmitted directly to the control bar, so that its control linkage is largely independent.
  • a further preferred embodiment of the invention provides that the screwing unit is arranged on a slide that can be moved vertically along a vertical rail.
  • the slide has rollers that enclose the rail on both sides and is supported on a gas pressure spring aligned parallel to the lifting sleeve.
  • the centering block belonging to the holding device delimits the lifting sleeve at its lower end. It is essentially cuboid in shape.
  • a particularly preferred embodiment of the invention provides that the centering block of the holding device is bell-shaped.
  • each configuration of the centering block serves, in which a plate one Fastener can at least partially immerse. This is particularly advantageous for oval support plates. By partially immersing the plate in the centering block, it is protected against twisting around the longitudinal axis of the fastener.
  • the bell shape is achieved, for example, by milling a concave curvature on the underside of the centering block. The curvature is expediently designed so that it corresponds to the curvature of the oval, curved support plate of a fastener.
  • edge strips are formed on the longitudinal sides of the centering block, which protrude beyond the curvature of the centering block, the centering safety is further improved. A twisting of the fasteners is then completely ruled out because the support plate strikes the inside of the edge strips.
  • the centering block is penetrated by a grommet in the region of the screw-in axis, which protrudes beyond the base of the arch.
  • the grommet plunges into the lifting channel of a two-part fastening element and gives it a pre-alignment, which the screwdriver linkage follows.
  • the grommet is pushed back or removed.
  • a further advantageous embodiment of the invention provides that the fork arms of the gripper on each of their parallel adjacent walls have a step-shaped shoulder, which interlock in the closed position of the gripper, the fork arms each having a keyway in this area.
  • the shank of the fastener is securely clamped in the adjacent keyways that complete a prism.
  • the shaft cannot be displaced against the jaws or transversely to them.
  • the fastening element is thereby precisely aligned in the screw-in axis. This is particularly advantageous when working on roofs with a slight slope.
  • a further advantageous embodiment of the invention provides that the fork arms of the gripper each consist of a clamping jaw and a joint plate, the joint plate being arranged orthogonally to the respective clamping jaw.
  • this has the advantage that both parts can be made from different materials.
  • the fork arm does not have to be completely replaced if it is worn or damaged.
  • a further advantageous embodiment of the invention provides that the fork arms of the gripper each have a pin on the back of their articulated brackets, which extends the longitudinal axis of the respective fork arm and can be rotated about the respective longitudinal axis. This eliminates almost any frictional force influencing the control and the device is easy to operate.
  • a further advantageous embodiment of the invention provides that the ejection end of the magazine is formed from two largely Z-shaped fingers, each of which has a slide directed against the gripper. This creates a transition zone in which the fastening element automatically engages after it has been separated, even when the device is tilted, as is customary on roofs with a slight slope.
  • a further advantageous embodiment of the invention provides that at least one of the fingers is arranged on the magazine in a foldable or pivotable manner.
  • the proposed measure provides a means with which a holder that has already been placed can be removed from the device in the event of a malfunction of the device.
  • the pivotable or foldable finger is expediently mounted on a spring-loaded ball which is inserted in the magazine or in the magazine wall. The ball exerts a compressive force on the finger so that it cannot move out of its closed position automatically.
  • the handle is at least foldable or pivotable. This is particularly advantageous when working on the roof edge, close to the parapet.
  • the stroke is cleared by folding or swiveling the handles. This means that the user can drive so close to the parapet with the device according to the invention without hitting the parapet with the handle.
  • the handle can be swiveled in so that it glides past the parapet at a sufficient distance during the downward stroke.
  • a handle part can be inserted, for example, into the adjacent handle part. If necessary, the plug connection is released.

  • the fork arms When lowering the screw unit 4 and thus the centering block 9, the fork arms are guided downward by the control grooves 16, 17. In the upper section of the control cams, as soon as the fork arms 18, 19 emerge downward from their top dead center O ⁇ , they are moved towards one another due to the course of the control curve.
  • the fork arms 16, 17 thus perform a pliers movement in the area of the cam position KP and clamp the shaft 69 of the fastening element 65 between them.
  • the fastening element 65 is thus also aligned in an assembly-appropriate position, so that it cannot escape from the screw-in axis 3 until the screw rod is immersed in the lifting channel 82 of the fastening element 65. It is therefore immaterial whether work is carried out on a horizontal plane or on an inclined roof surface.
  • the holding device always aligns the fastening element in the screw-in axis 3.
  • the fork arms 18, 19 pass through the lower curve region 83, 85 and distance themselves from one another to such an extent that they emerge laterally under the support plate 80 and release the fastening element 65 in its entirety when the fork arms 18, 19 reach their bottom dead center UT at the curve exit 83.85.
  • the screw 84 of the fastening element 65 has already drilled the subsurface in this phase, so that the drill tip immersed in the fastening element does not allow the fastening element to drop out or leave the screw-in axis.
