Definitions

  • the invention relates to a paint application machine for painting motor vehicle bodies with at least one movement device that has one or more paint application devices that are dynamically connected to it, that are moved linearly by the movement device in two spatial axes lying transversely to the conveying direction of the bodies and are pivoted about at least one spatial axis.
  • Paint application machines are known for painting car bodies, in which the paint application devices are moved transversely to the conveying direction by devices arranged on the side or above the body along the surface of the body.
  • the distance between the paint application device and the paint spraying distance should always be the same over the entire surface and the application direction should always be perpendicular to the surface.
  • a contour machine according to European patent application (publication no. 0 338 334 A) is known, in which ink application devices are driven linearly along two spatial axes and rotatable about two spatial axes via several motors. Since this arrangement can only perform relatively slow movements, especially in the X and Z axes, it is not suitable for the front and rear parts of vehicles.
  • the individual bodies follow at short intervals. Ink application devices that are only moved in the X and Z axes, such as B. with the known contour machine described above, are too slow to move into and out of the spaces between the bodies during the remaining time without collisions with the bodies.
  • Another known ink application machine also does not solve this problem, although this very rapid movement of the ink application devices in the X and Z axes enables it.
  • This known arrangement uses a yoke portal, which is displaceable in the lateral frames in the vertical direction (Z axis).
  • the yoke portal can be pivoted about the X axis and carries a displacement unit which can be displaced in the X axis.
  • the displacement unit is equipped with paint applicators, which in turn can be pivoted about the Y axis. Even with this device, the front and rear sections cannot be painted properly.
  • the object of the invention is to paint even long front and rear parts of bodies in a continuous process.
  • the stated object is achieved in that the movement device is assigned means which make it possible to move the paint application devices in a third spatial axis, which lies along the conveyor device of the body to be painted.
  • the advantage of the invention is that by moving the paint application devices in the third axis (Y axis), the paint application devices can run in a certain working area with the bodies in the conveying direction, even if the movement device is stationary with respect to the conveyance.
  • the means assigned to the movement device consist of at least one linear movement device and at least one swivel device, which are combined in their movements for moving at least one paint application device in a spatial axis lying along the conveying direction. Since the car bodies practically only have curved surfaces, it is necessary to give the paint applicators multidimensional movements.
  • the linear movement device consists of at least one lifting device and at least one swivel shaft mounted rotatably in the same
  • the swivel device consists of at least one swivel arm connected to the swivel shaft and a cross portal arranged at a distance from the swivel shaft
  • the cross portal a cross slide device carries that the cross portal is pivotally mounted in the swivel arm
  • the cross slide device carries a swivel mechanism to which at least one paint application device is articulated.
  • the modular and flexible structure and the stationary drives enable the paint application machine according to the invention to be used inside or outside a spray booth.
  • FIGS. 1 and 2 basically show the same basic arrangement according to the invention. The differences lie in the choice and the sequence of movements of the paint application devices. The elements of the basic arrangement and their description therefore apply to both embodiments in FIGS. 1 and 2.
  • the basic arrangement has a paint application machine 1, which is arranged, for example, in a spray booth 2 of a car body painting system.
  • Car bodies are moved in the conveying direction F between a left side wall 30 and a right side wall 31 of the spray booth 2, in order to be covered with a layer of paint.
  • a left side module 4 is arranged in the left side wall 30 and a right side module 5 is arranged in the right side wall 31.
  • the side modules 4 and 5 are movement devices which are equipped with drive elements (not shown) for the paint application machine 1 and their movement elements.
  • Means are assigned to each movement device, which impart different-axis movements to one or more paint application devices. These means consist of swivel and linear movement devices.
  • a left lifting device 6 is assigned to the left side module 4 and a right lifting device 7 is assigned to the right side module 5.
  • Each lifting device 5, 6 is provided with a swivel device 60, 61.
  • the left lifting device 6 carries a left pivot shaft 8 and the right lifting device 7 a right pivot shaft 9.
  • the pivot shafts 8 and 9 lie in a common horizontal axis 14. Both lifting devices 6 and 7 move the pivot shafts 8 and 9 in the direction of a vertical axis designated 10.
  • a recess 3 in the side modules 4 and 5 enables the swivel shafts 8 and 9 to move vertically V.
  • the vertical movement V takes place between an upper turning point 12 and a lower turning point 13. Between the points 12 and 13, the horizontal axis 14 executes a vertical useful stroke 11.
  • the vertical axis 10 is fixed relative to the spray booth 1 or the conveying direction F.
  • Both pivot shafts 8 and 9 are coupled to one another in such a way that they can be moved together about the horizontal axis 14 in the direction of a pivoting movement S1.
  • the swiveling movement S1 takes place in the region of a swiveling angle 17.
  • the drive for the swiveling movement S1 lies, not shown, in the side modules 4 and 5.
  • the left swivel shaft 8 is fixedly connected to a left swivel arm 15 and the right swivel shaft 9 to a right swivel arm 16.
  • the swivel arms 15 and 16 therefore carry out the same swivel movement S1 as the swivel shafts 8 and 9.
  • the left side arm 15 carries a left axis 21 and the right pivot arm 16 carries an axis 22.
  • Each of the axes 21 and 22 lies at a distance 18 from the axis 14 on the respective pivot arm.
  • the two axes 21 and 22 therefore lie on a common pivot axis 19.
  • the pivot axes 21 and 22 are connected to one another via a transverse portal 20.
  • the cross portal 20 consists of a cross portal axis 24, which thus also lies on the pivot axis 19.
  • the axes 21 and 22 are pivotally mounted in the respective pivot arms and are set in pivoting movement S2 about the pivot axis 19 by drive means (not shown).
  • Power transmission means are provided in the swivel arms 15 and 16 and within the leg shafts 8 and 9.
  • the drive itself takes place in the respective side modules 4 and 5.
  • the swivel movement S2 takes place within a swivel angle 23.
  • the pivoting movement S2 about its own pivot axis 19 is possible.
  • 63 schematically shows a drive connection which could, for example, couple the drives of the side modules 4 and 5 to one another.
  • the transverse portal axis 24 is provided with a paint application device 27 which throws paint particles against a body in the application direction A
  • the paint application device 27 can be moved on the one hand in or against the conveying direction F by the combination of the movements V, S1 and S2.
  • the application direction A can take place at different angles 34 with respect to a perpendicular 33 to the conveying direction F or parallel to the vertical axis 10.
  • the application direction A is opposite to the conveying direction F i.e. the angle 34 is negative.
  • the ink application device 27 "is such that the application direction A" points in the conveying direction F, i.e. the angle 34 "is positive.
  • the paint application device 27 has a trailing distance 46 with respect to the vertical axis 10. In the dashed position, the paint application device has 27 'with respect to the vertical axis 10 a lead distance 47.
  • FIG. 4 shows a car body spraying system 45 with a leading body 35 which has a body surface 39 and a trailing body 36 which has a body surface 40.
  • the bodies 35 and 36 follow one another at a distance 37 in the conveying direction F.
  • An order distance is denoted by 38 in which a paint applicator 27 is located opposite the surface of the car body.
  • a dash-dotted line 41 is drawn along the body surfaces 39 and 40, which thus indicates the position of one or more paint applicators 27 during the spraying process. Since the paint must always be applied perpendicularly to the body surfaces 39 and 40, the angle 34 shown in FIG. 3 must always be adapted to the respective surface point.
  • the ink application machine 1 is only shown schematically.
  • a point 42 is drawn on the dash-dotted line 41. The same marks the position of the paint application device 27 relative to the last surface point of a rear section 48 on the body surface 39 of the lead body 35, which has to be sprayed.
  • a point 43 marks the position of the paint application device 27 relative to the first surface point of a front part 59 on the body surface 40 of the trailer body 36, which has to be sprayed.
  • a dotted line 44 between points 42 and 43 represents the movement sequence of the paint application device 27.
  • the direction of paint application A at point 42 is practically or approximately the same as the conveying direction F. At point 43, however, the direction of paint application is opposite to the conveying direction F.
  • the paint application device 27 practically changes the order direction by 180 °.
  • the ink application machine 1 or the ink application device 27 Since the bodies follow one another at relatively short intervals 37 in practical operation and the throughput speeds are also relatively high, it is necessary for the ink application machine 1 or the ink application device 27 not only to be able to perform a vertical movement V and a swivel movement S2, but also additionally a swivel movement S1.
  • this enables the paint application device 27 to run ahead or behind the vertical axis 10 fixed in the spray booth 1.
  • a transverse displacement device 62 with a displacement ring 25 is further arranged on the transverse portal axis 24.
  • the latter can carry out a horizontal transverse movement H with a horizontal stroke 26 on the transverse portal axis 24.
  • the horizontal stroke 26 corresponds to the useful stroke of the machine.
  • the sliding ring 25 is provided with a pivot mechanism 28.
  • the same moves about a pivot axis 32.
  • the pivot axis 32 runs, for example, parallel to the conveying direction F.
  • the pivot mechanism 28 carries two spray guns 52, 53 which perform a pivoting movement S3 about the pivot axis 32.
  • the swiveling movement S3 takes place within a swiveling angle 29.
  • corner parts 49 and 50 (FIG. 5) of a car body roof 51 can be provided with paint as required.
  • a plurality of paint application devices 27 which are connected to one another are further provided, in the example shown being electrostatic spray bells 54, 55, 56.
  • the spray bells 54, 55, 56 move in parallel with one another in an oscillating movement 0.
  • the spray bells 54, 55, 56 are arranged at adjustable distances 58.59 from one another.
  • the amplitude of the oscillation movement 0 is such that the paint application spray mists of the adjacent spray bells complement each other and result in a color layer on the body surface which is balanced in terms of thickness and area uniformity.
  • the spray bells 54, 55 and 56 also perform the pivoting movement S2 about the pivot axis 19.
  • one or more paint application devices can be attached to the cross portal.
  • the ink application machine is preferably constructed modularly, e.g. side modules and connecting modules arranged transversely to it (cross portal).
  • the coupling takes place by means of swivel arms between the side module and the cross portal.
  • the movements required for an application (number of axes) and movement lengths (useful strokes and swivel angles) are specifically selected according to the given needs.
  • the drives provided for the axis movement are stationary so that the risk of cable breaks can be avoided.
  • the special flexibility of the paint application machine 1 allows it to be used inside or outside a pointed booth 2.
  • the side modules 4, 5 are arranged outside the booth.
  • the swivel arms 15, 16 and the transverse module 20 are located within the cabin 2.
