Definitions

  • the invention relates to a device for cleaning objects, in particular of workpieces, with at least one rotatable about a first axis of rotation rotatably mounted head, on which a plurality of at least one pressure line for a cleaning medium connected and arranged obliquely arranged nozzles are arranged.
  • This type of equipment is used, for example, in the manufacture of products such as automotive engines.
  • the cleaning usually upstream and downstream processes are connected. Therefore, it is often necessary to perform the cleaning as quickly as possible within a cycle.
  • Object of the present invention is now to provide a device that guarantees a uniform and comprehensive cleaning without a translational movement along the workpiece surface.
  • this device has at least one arm which is rotatably mounted at a first end, wherein the rotary nozzle head is rotatably mounted on the arm.
  • compressed air As a cleaning medium compressed air is provided, since it can be used for drying, as well as for cooling and cleaning. In addition, compressed air is cheap and readily available and easy to use. It when the device has at least two arms, wherein the arms are arranged rotationally symmetrical about the first end is particularly advantageous. This can reduce the time required for cleaning. Moreover, the device is mechanically improved as it loses its imbalance when the arms are rotationally symmetric.
  • a preferred embodiment of the device results from the fact that the obliquely set nozzles of the rotary nozzle head with the first axis of rotation form an angle, which preferably has an angular range of greater than 0 ° to 10 ° and more preferably an angular range of 1 ° to 3 °.
  • This particular arrangement of the nozzles on the rotary nozzle head results in turn by the ejection of the cleaning medium in turn a rotational movement of the rotary nozzle head, therefore, no drive of the rotary nozzle head is necessary.
  • the cleaning performance is improved with respect to an axial alignment of the nozzles, since the unwanted particles are better moved from the workpiece surface in the direction of the environment.
  • cleaning performance is understood here a size related to cleaning speed and actually cleaned area. The higher the cleaning speed and the larger the actual cleaned area, the greater the cleaning performance.
  • first axis of rotation of the rotary nozzle head is arranged inclined to the second axis of rotation of the arm, wherein an angle of incidence of the first axis of rotation to the second axis of rotation preferably an angle range between 0 ° to 10 °, particularly preferably an angle range between 1 ° and 3 ° having.
  • a particularly simple embodiment results when the arm has cleaning nozzles, which are flow-connected to the pressure line. As a result, it can be achieved that the arm rotates independently through the cleaning medium outlet, without the hiring of the rotary nozzle head being necessary. Furthermore, the rotational movement is caused by these additional cleaning stabilized nozzles and the cleaning performance can also be significantly improved.
  • the arm has at least one second rotary nozzle head. This results in a larger area which is covered by the cleaning medium for a constant period of time.
  • the device has at least one housing around at least one arm, wherein the housing is open towards an insert surface of the cleaning medium. This measure increases the safety because the rotating parts are covered. Furthermore, it is advantageous for the guidance of a flow of the cleaning medium when the housing assumes this task of targeted flow guidance to the application area.
  • the housing means that pollution from surrounding machine parts can be reduced, which in turn has positive effects on machine availability.
  • the device has a feed mechanism, in particular a pneumatic or hydraulically actuable working cylinder, for the axial movement of the arm.
  • An embodiment which is particularly favorable results when a diameter of the rotary nozzle head to a length of the arm has a ratio which is in a range of 1.6 to 1.9, the length from the first end to a puncture point the first axis of rotation is measured with a plane in which the arm is located. This results in the advantage that the cleaned surface on the surface of the workpiece is particularly covering in comparison to other embodiments.
  • FIG. 1 shows a device according to the invention in a first embodiment in a sectional side view.
  • Figure 2 shows the device in the first embodiment in a section along the line II-II in Fig. 1.
  • FIG. 3 shows the device according to the invention in a second embodiment in a side view.
  • 4 shows the device according to the invention in a third embodiment in a side view;
  • Fig. 5 shows the device according to the invention in a fourth embodiment in a Schrägriss.
  • a device 1 according to the invention is shown in a first embodiment.
  • This device 1 for cleaning workpiece surfaces has two arms 10.
  • Each arm 10 is rotatably mounted about a first end 11.
  • the device 1 has two rotary nozzle heads 20 which are rotatably mounted on a respective arm 10 about a first axis of rotation 21.
  • 20 inclined nozzles 22 are arranged on the rotary nozzle heads.
  • the arms 10 are arranged rotationally symmetrically about the first end 11. Subsequently, only a single arm 10 will be described, since the arms 10 are made equal.
  • the pressure line 2 is formed from a first connection 24 in the rotary nozzle head 20, a second 12 in the arm 10, a pressure hose 3 and a first bore 23 of a first rotary joint 25 and a second bore 13 of a second rotary joints 14.
  • the first rotary joint 25 realizes the rotatable mounting of the rotary die head 20 about the first axis of rotation 21 and the second rotary joint 14, the rotatable mounting of the arm 10 about a second axis of rotation 15, which is defined by the first end 11.
  • the pressure hose 3 establishes a further flow connection between the second bore 13 and, for example, a pressure accumulator, not shown, for the cleaning medium.
  • the arm 10 has cleaning nozzles 16, which are connected to the pressure line 2 analogously to the nozzles 22.
  • a ratio D / A which relates a diameter D of the rotary nozzle head 20 to a length A, for example in a range between 1, 6 and 1.9.
  • the length A is defined as the distance measured in a plane 17 between a first piercing point 27 of the first axis of rotation 21 through the plane 17 and a second puncture point 18 of the second axis of rotation 15 through the plane 17, wherein a longitudinal axis 19 of the arm 10 is a level 17 element and the plane 17 forms a normal plane to the second axis of rotation 15.
