Definitions

  • the present invention relates to a rotatingly driven floor cleaning device with a plurality of interchangeable work tools fastened on the periphery of a rotary body.
  • a floor cleaning device and a working tool is from the script DE 94 11 562.1 known.
  • a sweeping brush is disclosed there, which is used in particular to mechanically eliminate wild herbs of all kinds on paved surfaces.
  • the work tools such as braided wire, flat wire steel tufts, plastic tufts mixed with wire or braided wire to a steel rope, are attached to a turntable that can be driven in rotation. If the bottom ends of the work tools touch the ground during the rotary movement of the turntable, wild herbs that are in the effective area of the work tools are damaged, separated from the root system and removed.
  • the work tools each have a shaped body on their side facing away from the floor.
  • the molded body is a clamping sleeve, which surrounds the tufts of wire or steel rope from the outside and holds them clamped.
  • the cross-sectional shape of the working tool projects laterally across the longitudinal axis of the working tool in an adjoining section of the working tool facing the floor and forming the tool part, namely the tufts of wire or the steel rope that are clamped in the clamping sleeve .
  • the floor cleaning device can be used as a hand-held device, as an attachment to carrier vehicles, or as a separate one that is pushed or provided with a wheel drive Device be trained.
  • a wheel drive Device For example, garden tractors, municipal vehicles or tractors can be considered as carrier vehicles, and several floor cleaning devices can also be mounted next to or behind one another on larger carrier vehicles or own devices.
  • the turntable can be driven by a combustion, hydraulic or electric motor or a drive shaft which is connected to the drive of a carrier vehicle. Satisfactory work results can be achieved with such a device.
  • the working tools are subject to considerable wear during use and must therefore be replaced again and again.
  • several work tools can be attached to it.
  • twelve work tools are shown, which are attached to the turntable via a joint.
  • the PTO shaft In order to replace a work tool, the PTO shaft must be removed from its installation position, the work tool removed, the new work tool brought back into the installation position and the PTO shaft must be installed again in its installation position.
  • Such a conversion is not possible without special tools.
  • the screws and nuts with which the PTO shaft is fastened often have to be cleaned and made to work before they can even be worked on. While a single work tool can still be replaced in a manageable amount of time, this results in a considerable amount of time being spent on several work tools.
  • a generic floor cleaning device with bristles held in shaped bodies is known from the document DE 16 32 382 A1 known.
  • the shaped bodies of the bristles are inserted into a perforated disc, which in turn is screwed is attached to a driving plate.
  • the driving plate is connected to a drive via a shaft. To replace the bristles, the disc must be completely removed from the plate.
  • bristles with shaped bodies can be found in the writings US 2009/119858 A1 , EP 1 419 713 A1 , EP 1 623 652 A1 , GB 861 958 A , US 3,101,501 and DE 39 37 053 C1 .
  • the shaped bodies are each inserted in a comparable manner into a rotatingly drivable disk which is connected to a driving plate. In these versions, too, the exchange of the bristles with the shaped bodies is complex.
  • the clamping elements can be turntables, at least one of which is driven in rotation.
  • the turntables do not have to have a closed surface, they can also have openings, for example for reasons of weight or the air flow within the floor cleaning device.
  • the clamping elements can jointly form the rotating body to which the work tools are attached on the circumference.
  • the clamping device can be one or more screws, clamping clips or tensioning wires with which the clamping elements in the holding position are held together. Due to the holding position of the clamping elements, the shaped bodies are initially held in a positive manner in their working position. However, such holding forces can also be applied to the clamping elements by means of the clamping device (s) such that they also hold the molded bodies of the working tools in a frictional manner on their outer circumference between them in the holding position. In this way, the work tools cannot unintentionally detach themselves from their installation position even at the usual rotational speeds of a rotating body.
  • the receiving pocket is closed by the two clamping elements in the holding position of the clamping elements, the receiving pocket is at least opened so far after a lifting movement of one clamping element from the other clamping element that the molded body of a work tool held in the receiving pocket can be removed from the receiving pocket.
  • closed, form-fitting receiving pocket is not to be understood in such a way that in the holding position of the clamping elements, it must be completely closed to the outside on the circumference and / or to the top and bottom. Closed in the sense of the invention means that the shaped body is at least positively embraced by the clamping elements in the holding position in such a way that it can no longer be unintentionally released from the receiving pocket, even if pressure is exerted on the work tools due to work and / or the work tools are relieved.
  • a receiving pocket does not have to completely enclose a shaped body, it is sufficient if the shaped body - for example on lateral edges - to the extent that it is positively encompassed so that it cannot unintentionally detach from the receiving pocket. If this is ensured, joints, holes and slots may still be open to the outside in the area of the receiving pocket in the peripheral area of the molded body. Such openings can even be advantageous in order to avoid or at least reduce the accumulation of dirt in a receiving pocket.
  • a minimum form of a form-fitting receiving pocket can thus guide the molded body in a laterally adjacent manner at at least two points and form-fitly prevent it from falling out unintentionally by means of a front locking tab.
  • each of the two clamping elements forms part of the receiving pocket, at least in the holding position, because then with a movable clamping element, part of the receiving pocket is movable in relation to the other part, thereby enlarging and reducing the size of the receiving pocket for removing and installing a molded body can be, whereby also advantageously one of the clamping elements, in particular the not so easily movable clamping element, can serve as a kind of stop.
  • the constriction is advantageously formed on one of the clamping elements.
  • the constriction can be dimensioned such that after a lifting movement of one clamping element from the other clamping element, the bottom opening is no longer blocked, so that the molded body can then be easily removed from the receiving pocket.
  • the shape of the shaped body and the shape of the receiving pocket are thus coordinated with one another in such a way that a positive position of the shaped body in the receiving pocket is established in the holding position of the clamping elements.
  • the manufacturing costs for the work tools are reduced because they no longer have to have bores, threads and the like.
  • a suitable shape of the molded body is sufficient.
  • the form-fitting fixation of the molded bodies in the holding position of the clamping elements also reduces the risk that work tools could become unintentionally released during operation due to possible assembly errors. It is sufficient to hold the holding elements clamped together again by the clamping means in order to securely lock the work tools in their installed position. So only the clamping device has to be securely fastened again.
  • a fastening bolt extends from a first clamping element to the second clamping element, which is rigidly connected to the first clamping element and, in the holding position of the clamping elements, extends through one end of the second clamping element through an opening in the second clamping element, the clamping means being in the holding position on this end is put on.
  • the fastening bolt also offers a good way of bracing the two clamping elements against one another.
  • the fastening bolt can be designed, for example, as a screw bolt on which a clamping screw can be placed.
  • the clamping screw can be designed, for example, as a wing screw, which can be screwed on and screwed on without tools.
  • a clamping screw is advantageous because it can only be unscrewed as far as is necessary to be able to remove the working tools from their installation position in the respective receiving pocket. It is then not necessary to completely lift the second clamping element off the first clamping element. In this way, it can be avoided that several or all of the work tools accidentally fall out of their installation position in an uncontrolled manner after the clamping device has been released.
  • a screw as a clamping means
  • other clamping means can also be easily detachable and fastened again on the fastening bolt.
  • the length of the fastening bolt can be such that the clamping means can only be fastened to it when all the working tools are in a secure desired position. This reduces the possibility of maintenance errors.
  • the fastening bolt is placed on the drive shaft of the clamping elements.
  • the drive shaft offers a good fastening option for the fastening bolt. It is well supported by its bearing against the machine frame and can easily absorb the forces and dissipate it into the rest of the device, which act on the floor cleaning device and in particular on the working tools and the clamping elements during operation of the device.
  • the first clamping element is guided against the second clamping element via guides in the lifting direction in its lifting movement, the guides being rigid with the first clamping element are connected.
  • the guides prevent twisting of the clamping elements relative to one another.
  • the guides can consist, for example, of cylindrical pins connected to the first clamping element, via which the second clamping element can slide up and down with correspondingly dimensioned guide holes. This ensures that the clamping elements are always in the correct relative position to one another so that the shape of the receiving pockets can be closed securely and functionally. This reduces the risk that a shaped element in an accommodating pocket could tilt incorrectly.
  • the play between the elements of the first and second clamping elements which form the guide also determines to what extent the second clamping element can be moved with respect to the first clamping element.
  • the play can in particular limit the tilt angle by which the second clamping element can be raised relative to the first clamping element.
  • a limited tilt angle is particularly advantageous if the second clamping element should only be able to be raised to such an extent in the area of a receiving pocket that a work tool can only be removed from this receiving pocket and a new one can be inserted. This prevents work tools that have already been replaced from falling out of the receiving pocket when a working tool is removed from the receiving pocket at a different location of the clamping elements.
  • the guides have a stop, through which the stroke movement capacity of the second clamping element is limited. Due to the stops, the second clamping element cannot unintentionally detach from the first clamping element without having to be held for this. This also simplifies the tool change.
  • the stops also increase the safety of the device, because the second clamping element cannot unintentionally detach from the first clamping element during operation of the device; it can be held in a position in which it is the molds of the work tools still secure against accidental falling out.
  • the shaped bodies have a non-circular cross-sectional shape.
  • the non-circular cross-sectional shape of the molded body prevents it from being able to rotate with the working tool in the receiving pocket during operation.
  • the floor cleaning device works more precisely if the working tools are held in a receiving pocket in a rotationally fixed manner.
  • the non-circular cross-sectional shape can be realized, for example, with an oval, quadrangular, hexagonal or octagonal cross-section of the shaped body in the area of the receiving pocket.
  • the clamping elements form a plurality of receiving pockets and are arranged concentrically to one another.
  • the concentric arrangement results in an identical effect on the molded body when a clamping element moves in relation to the other clamping element: either all are held more firmly in the receiving pockets at the same time, or all are released at the same time. This reduces the assembly effort when changing the work tools.
  • the concentric arrangement is particularly advantageous if a clamping element can be moved along the fastening bolt, which enables central alignment and guidance.
  • At least one energy accumulator is arranged between the first and second clamping elements, which force pushes the two clamping elements apart at least in the holding position.
  • a spring can be considered as the energy store.
  • the energy store serves the purpose of keeping the clamping elements as free of play as possible. Even if the tension screw is partially solved, the energy accumulator can advantageously help to keep the second clamping element in a play-free target position. This also makes it easier to remove and install new work tools.
  • the receiving pockets have a longitudinal central axis which is at an angle to the direction of force of the clamping means.
  • the clamping force which the clamping means exerts on the second clamping element is transmitted directly to the contact surfaces of the molded bodies and the receiving pockets which are arranged obliquely along the longitudinal central axis of the receiving pockets. This results in a direct clamping force on the shaped bodies, which are not only held positively, but also non-positively in the respective receiving pockets.
  • the receiving pockets have, at their end facing away from the floor, a surface which is bevelled to the longitudinal central axis of the receiving pocket.
  • the beveled surfaces can be formed in particular on the clamping element facing away from the floor. The beveled surfaces make it possible for the shaped bodies to wedge in their receiving pocket if they are not shaped to the exact shape of the receiving pocket or if the clamping elements are not sufficiently tightly clamped to one another.
  • a molded body when it is pressed upward by a contact of the work tool with the floor, slides with an upper edge against the beveled surface and rotates in relation to the longitudinal central axis of the receiving pocket until it is wedged within the receiving pocket can not slide further up, because the shaped body abuts the side walls of the receiving pocket at other points along its circumference. Because of the inclined surface not exactly dimensionally stable molded bodies are firmly fixed, and also a game between the clamping elements in the receiving pockets due to an insufficiently tensioned clamping means can be compensated for via the beveled surface.
  • the first clamping element and the second clamping element each have a bowl shape, the peripheral edges of which are angled to extend to the plane of rotation on the floor.
  • the second clamping element has a smaller diameter than the first clamping element, so that the second clamping element is at least partially received by the first clamping element in the holding position.
  • a fail-safe device is arranged on one of the clamping elements in the area of a receiving pocket.
  • the failover can consist, for example, of a clamping tab or a retaining spring.
  • the failover is advantageously designed to be so flexible that the failover yields on the one hand when a work tool moves past it with emphasis is, on the other hand, exerts such a holding force on a work tool that the fail-safe device keeps it stationary in the respective position.
  • the failover can remain permanently in the respective installation position. This saves additional assembly steps, and the failover is then almost impossible to lose.
  • the fail-safe can additionally protect the working tools not only during assembly, but also during the operation of the device. This increases the operational reliability of the device.
  • the failover is advantageously arranged and designed such that it holds the work tool at the transition from the tool part to the molded body. The projection which the molded body forms in this area in relation to the tool part then generates an additional positive holding force against undesired falling out.
  • FIG. 4 shows an oblique top view of an exemplary floor cleaning device 2.
  • the floor cleaning device 2 via a motor 4, an axle with two wheels 6 and a front cover 8, under which the in Fig. 2 Rotation body 10 shown in cross section is located.
  • the floor cleaning device 2 can also be designed as a hand-held tool or as an attachment for a carrier vehicle.
  • the floor cleaning device 2 has only a single rotating body 10, but it is also conceivable that the floor cleaning device 2 has a plurality of rotating bodies 10 which can be arranged next to one another, partially offset one behind the other or in any other arrangement.
  • the Fig. 2 shows a cross-sectional view through a rotating body 10.
  • a fastening bolt 14 is placed on the drive shaft 12, with which a first clamping element 16 and a second clamping element 18 are connected. While the first clamping element 16 and the fastening bolt 14 are firmly connected to the drive shaft 12 in the exemplary embodiment, the second clamping element 18 is movable on the fastening bolt 14 in the stroke direction H.
  • the second clamping element 18 is held in its position by a clamping screw 20 which is screwed onto the fastening bolt 14.
  • a tension spring 22 is placed on the fastening bolt 14. When the tension screw 20 is screwed in, the tension spring 22 is pressed in. In the pressed-in position, the tension spring 22 exerts a tension force stored in it on the second clamping element 18, which is pressed away by the first clamping element 16.
  • FIG. 2 the clamping elements 16, 18 are shown in a holding position in which the clamping elements 16, 18 each consist of a steel rope 24 and a molded body 26 keep existing work tools 28 clamped.
  • a work tool 28 is shown on the right, in which the cross-sectional shape of the shaped body 26 in a section transverse to the longitudinal axis L of the work tool 28 projects beyond the cross-sectional shape in the area of the steel throat 24 by a protrusion dimension 30.
  • the longitudinal axis L of the working tool 28 and the longitudinal central axis of the receiving pocket 32 are shown in FIG Fig. 2 identical and indicated by a dashed line.
  • the second clamping element 18 there is an opening 36 through which the fastening bolt 14 is passed. With the opening 36, the second clamping element 18 is movable in the stroke direction H along the fastening bolt 14. In the exemplary embodiment, the second clamping element 18 is additionally guided in its lifting movement by guides 38.
  • the guides 38 shown are shown in a sectional view. In this sectional view, a screw bolt can be seen, which is surrounded by a sleeve in the stroke area.
  • the guide 38 has a stop 40 at the bottom, through which the stroke movement of the second clamping element 18 is limited.
  • the receiving pocket 32 has a beveled surface 42 upwards, through which the cross section of the receiving space tapers in the receiving pocket 32. If the shaped body 36 should move further upward in the receiving pocket 32, it hits the beveled surface 42 which, due to its angle of attack, inhibits an upward movement of the shaped body 26 and blocks it at some point depending on the geometric conditions.
  • Fig. 3 the rotating body 10 is shown in an open position.
  • the second clamping element 18 has been displaced downward in relation to the first clamping element 16.
  • the second clamping element 18 lies on the stops 40 in the region of the guides 38. Due to the stroke movement H downward, the second clamping element 18 has been displaced so far downward with respect to the first clamping element 16 that the shaped body 26 of the working tool 28 is no longer held in the receiving pocket 32 in a form-fitting and non-positive manner. Rather, the receiving pocket 32 is opened so far that the molded body 26 can now be removed from the receiving pocket 32 obliquely to the side.
  • Fig. 3 it can be seen that the clamping screw 20 has been unscrewed on the fastening bolt 14. As a result of the unscrewing movement, the tension spring 22 has been released. However, the tension spring 22 still has so much force that it fixes the second clamping element 18 in a centered orientation and position.

  • Fig. 6 can be seen in the enlargement that the molded body 26 is held in a form-fitting manner in the receiving pocket 32, the three-dimensional shape of the receiving pocket 32 being formed by wall sections of the first clamping element 16 and the second clamping element 18.
  • the molded body 26 is additionally secured in the receiving pocket 32 by the stop 40 against unwanted slipping out.
  • the 7 to 9 show the same elements as that 4 to 6 , but in an open position of the clamping elements 16, 18.

  • the second clamping element 18 may be connected in a rotationally fixed manner to the fastening bolt 14 and for the first clamping element 16 to be movable in the stroke direction H with respect to the second clamping element 18 instead of the second clamping element 18.
  • Fig. 10 shows a view from below of a rotating body with a fail-safe 46 attached to it.
  • the fail-safe 46 is designed and arranged in such a way that, in its installed position, it reduces the free cross-section of the opening at the bottom, at least in the holding position.
  • the fail-safe 46 is a spring which extends transversely to the longitudinal axis L of the working tool 28 and secures the molded body 26 in the axial direction against undesired sliding of the molded body 26 out of the receiving pocket 32. The securing still works even if one clamping element 16, 18 has already been lifted off the other clamping element 16, 18.
  • Fig. 11 shows a sectional drawing through a receiving pocket 32 with a fail-safe 46 located at its bottom end.
  • the clamping element 18 has already been lifted a little from the corresponding clamping element 16.
  • the molded body 26 of the working tool 28 can normally be removed well from the receiving pocket 32.
  • a molded body 26 could slide out of the receiving pocket 32 even without touching it. This applies in particular when work is currently being carried out on other work tools 28 of a rotary body 10 and when the clamping elements 16, 18 move the rotary body 10 at other points from the receiving pockets 32.
  • the fail-safe 46 in the form of a spring is located at the mouth opening 48 and holds a molded body 26 in its mounting position in the receiving pocket 32. The failover 46 can be pushed slightly aside because of its design as a spring when a molded body 26 is to be inserted into or removed from the receiving pocket 32.
