Definitions

  • the invention relates to a marking machine for producing marking lines from flowable marking material on traffic areas, such as roads, with a chassis and with at least one extruder which can be guided over the area to be marked, the extruder having at least one outlet opening which is arranged by at least one marking material container arranged on the chassis can be supplied with the marking material by means of at least one marking material pump through at least one marking material line, and the position of the extruder can be adjusted transversely to a direction of travel of the marking machine.
  • a marking machine for producing marking lines from marking material on traffic areas, such as roads, with an extruder which can be guided over the area to be marked and which has at least one outlet opening that can be supplied with the marking material by a marking material pump from a marking material container through a marking material line and the other with the rest Marking machine and connected to the marking material container by means of a swivel arm and is adjustable transversely to a direction of travel of the marking machine.
  • the extruder on the swivel arm can be pivoted between a position lying on a left side of the marking machine and a position on a right side of the marking machine, in each case outside a lateral contour of the other marking machine.
  • the axis about which the swivel arm can be pivoted runs either horizontally in the longitudinal direction of the marking machine or alternatively vertically, in each case preferably in the vertical longitudinal center plane of the marking machine.
  • connection which is necessarily articulated here over a large angular range the swivel arm and the marking material container represent a relatively high flow resistance for the marking material, which requires a correspondingly high pump output in order to ensure a fast marking process or which otherwise leads to limitation of the marking speed.
  • the handling of the marking machine when swiveling the swivel arm with the extruder is difficult because the extruder must be moved overhead and manually rotated and aligned in its raised position.
  • the swivel arm on the underside of the marking material container must be connected to the latter so that the necessary swivel angle is made possible; however, this means that there is no space under the marking material container, e.g. B. there to accommodate a burner and a combustion chamber for heating hot marking material to be processed, or that the marking material container must be arranged accordingly higher, but this comes at the expense of driving stability and tipping safety of the marking machine.
  • the object of the present invention is therefore to create a marking machine of the type mentioned at the outset which avoids the disadvantages mentioned and in which, in particular when conveying the marking material from the marking material container to the outlet of the extruder, there is little flow resistance and simplifies its handling for the operating personnel is.
  • the object is achieved according to the invention with a marking machine of the type mentioned at the outset, which is characterized in that the marking material container is mounted on the chassis such that it can be rotated about a vertical axis of rotation, and that the marking material line and the extruder as a unit together with the marking material container the chassis are rotatable.
  • the marking material line and the extruder always maintain their position relative to the marking material container, which enables inexpensive, less articulated or flexible elements in the line and thus low-resistance line design and line routing between the marking material container and extruder.
  • the Marking machine according to the invention simplifies handling because for an adjustment of the position of the extruder relative to the rest of the marking machine, the extruder and the marking material line only need to be raised a little and can then be moved together with the marking material container by rotating it around its vertical axis of rotation into a desired new position.
  • the unit comprising the marking material container, the marking material line and the extruder can be rotated by up to 180 ° about the vertical axis of rotation.
  • the range of rotation angles is expediently symmetrical to the longitudinal central axis of the marking machine, i.e. H. that the unit consisting of the marking material container, the marking material line and the extruder can be rotated through 90 ° on both sides from a central position in which the extruder lies on the longitudinal central axis of the marking machine.
  • the marking material line connecting the marking material container to the extruder is arranged in an intermediate space between an underside of the chassis of the marking machine and the traffic area to be marked, and that the extruder, viewed in the direction of travel of the marking machine, between one on a left side of the marking machine and one on the right side of the marking machine is adjustable outside a lateral contour of the rest of the marking machine.
  • the extruder can assume any intermediate positions between these extreme positions. If the marking material container, viewed in the longitudinal direction of the marking machine, is arranged between a front and a rear axle of the chassis, which makes sense for weight reasons, only positions in which a generated marking line would lie in the area of a bearing surface of wheels of the marking machine on the traffic area are excluded .
  • the invention proposes that the marking material container essentially has the shape of a standing cylinder and that the vertical axis of rotation along the vertical central axis of the marking material container runs. When the marking material container is rotated, its outer circumference therefore advantageously remains on a constant line.
  • the marking material container expediently has the maximum possible and permissible outer diameter and a maximum possible and permissible height in order to be able to carry as much marking material as possible in the sense of a long, uninterrupted marking operation.
  • the marking material container is expediently arranged on or in a rotary bearing which is arranged between the marking material container and the chassis. If the pivot bearing is designed accordingly, the marking material container can be rotated, but cannot tip over, connected to the chassis. In addition, there is the possibility to replace the marking material container for itself with little effort if necessary.
  • a rotary drive preferably a hydraulic or compressed air or electric motor, is expediently provided for rotating the marking material container.
  • the unit consisting of the marking material container, the marking material line and the extruder can preferably be locked relative to the chassis by means of a locking device in any rotational position, or in different steps.
  • An undesired and annoying automatic adjustment of the position of the unit consisting of the marking material container, marking material line and extruder relative to the rest of the marking machine is thus ruled out.
  • a further embodiment of the marking machine provides that the marking material line is also designed as a support arm for the extruder.
  • the marking material line advantageously has two functions, which advantageously keeps the expenditure on individual parts of the marking machine low.
  • the marking material line designed as a support arm for the extruder is by means of a swivel or swivel joint connected to the marking material container so as to be pivotable about a horizontal axis of rotation or swivel axis running transversely to the longitudinal direction of the marking material line.
  • the extruder can be raised and lowered in a technically simple manner at the outer end of the marking material line, which is remote from the container, relative to the rest of the marking machine and relative to the traffic area.
  • the extruder can be rotated by at least 180 ° about an axis vertical in its marking position, with an extruder-side end serving as a support arm Marking material line designed for the extruder is connected.
  • the extruder is also expediently lockable in the desired, set rotational positions relative to the marking material line.
  • the invention provides that the extruder has rollers and that in a marking position of the extruder, the marking material line designed as a support arm for the extruder is free in the vertical direction around the horizontal axis of rotation or pivoting is rotatable or pivotable and roll the rollers on the traffic area to be marked.
  • the extruder can thus automatically and precisely follow the course of the traffic area to be provided with the marking line, which ensures exact and uniformly wide marking lines.
  • a further measure to relieve the operating personnel of the marking machine is that the marking material line, which is designed as a support arm for the extruder, can preferably be lifted together with the extruder by means of a lifting drive from the marking position into a rest position in which the extruder is at a vertical distance from the traffic area vice versa.
  • a lifting drive from the marking position into a rest position in which the extruder is at a vertical distance from the traffic area vice versa.
  • at least one pneumatic or hydraulic cylinder which directly generates the lifting movement or alternatively a cable pull or lever arrangement which can be actuated by at least one pneumatic or hydraulic cylinder can be provided.
  • an extruder-side end be used as a support arm marking material line designed for the extruder and the extruder are connected to one another via a ball joint.
  • the marking machine is further provided for the marking machine according to the invention that the marking material pump is integrated in the marking material line. In this way, a particularly space-saving design is achieved, which is fundamentally advantageous for a mobile marking machine.
  • the marking material pump can be integrated into the marking material line particularly easily and inexpensively if, as is preferably provided according to the invention, the marking material pump is a screw pump and a screw conveyor of the marking material pump is arranged in the marking material line.
  • the extruder by means of a connection that only mechanically connects it to the marking material container, relative to the marking material container same axis as the marking material line is held pivotable separate holding frame.
  • the marking material line is designed as an articulated or flexible line with no load-bearing functions and that the extruder is held on a separate holding frame that only mechanically connects it to the marking material container and can be pivoted relative to the marking material container about the same axis as the marking material line .
  • a second marking material line is connected to the marking material container with a second extruder at its free end.
  • two marking lines can be applied in parallel.
  • the second extruder in series when viewed in the direction of travel of the marking machine is arranged with the first extruder.
  • an outlet of the marking material container connected to the marking material line can advantageously be arranged laterally in the lower container area, which means both good ground clearance, a safe low center of gravity of the marking machine and a relatively low filling height for the marking material and also a large space for accommodating an optionally necessary heating device, such as burner with combustion chamber and heating jacket, for the marking material in the marking material container.
  • the inside of the marking material container can be divided into two container sections, which then each hold one component of the marking material.

In this way, the extruder 4 can be adjusted relative to the remaining marking machine 1 in a direction transverse to its direction of travel 15 in order to be able to bring out a marking line 50 in different positions relative to the marking machine 1.
  • the extruder 4 In order to be able to guide the extruder 4 at a suitable distance from the traffic area 5 to be provided with a marking line 50, the extruder 4 has a pair of rollers 42 which roll on the traffic area 5 in the marking operation of the marking machine 1.
