Definitions

  • the invention relates to a method for cleaning folding rollers arranged on a robot arm and guided during folding along a folding flange, and to a cleaning station according to claim 8.
  • Sheet metal rebate connections are often made with industrial robots in automobile production in order to be able to adapt to differently designed components as quickly as possible.
  • the industrial robot presses an outer plate onto an inner plate with the folding roller arranged on the robot arm (cf. DE 100 11 854 AI and DE 299 10 871 Ul).
  • an adhesive is additionally applied to ensure the permanent durability of the rebate flange.
  • This adhesive can cause contamination of the running surfaces and the end faces of the folding roller when folding. When folding light metals, especially aluminum sheets, it can also lead to the adhesion and build-up of aluminum on the folding roller.
  • a generic method for cleaning the folding rollers is known from DE 100 01 205 Cl, the folding rollers being rotated relative to cleaning tools in a cleaning device.
  • the invention is based on the object of proposing a method and a cleaning station for the automatic cleaning of folding rolls in robot roll folding, the folding rolls being driven in a simple manner.
  • the folding roller attached to the robot arm is driven in a preferably stationary cleaning station for cleaning by means of a friction wheel, and preferably the running surface and / or the end faces of the folding roller can be cleaned mechanically with cleaning tools and / or with liquid cleaning agents.
  • the cleaning tools can in particular consist of brushes, scrapers or chisels, which can be pressed against the running surface and / or end faces of the folding rollers by movement in the x, y and z directions during the cleaning process, in particular with constant force.
  • the folding rollers are driven by means of friction wheels arranged at the cleaning station with a preferably reversible direction of rotation.
  • the friction wheels expediently engage an end face of the folding roller, preferably wherever experience has shown that no deposits of dirt form on the folding roller. In this way, contamination of this driven friction wheel is avoided.
  • This driven friction wheel can in particular be used to drive folding rollers with different dimensions and shapes. This makes it possible in particular to retrofit an existing roller folder with the cleaning station according to the invention.
  • This cleaning station only has to be arranged in the vicinity of the roll folding system within the effective range of the robot arm.
  • the cleaning station has a number of cleaning tools which can be moved simultaneously or successively during the cleaning process against the running surfaces and / or end faces of the folding rollers to be cleaned and preferably can be pressed against them.
  • the cleaning station expediently has a dirt collecting trough which is arranged below the working area of the cleaning tools, so that the dirt particles can be collected directly from this collecting trough.
  • the cleaning tools themselves can be cleaned with mechanical and / or liquid cleaning agents in their position above the drip pan.
  • Fig. 1 is a perspective view of the cleaning station according to the invention
  • FIG. 1 shows an enlarged detail of FIG. 1
  • Fig. 3 is a plan view of Fig. 1 and
  • Fig. 4 is a side view.
  • the robot arm to which the folding rollers 2, 3 are attached is not shown in the figures.
  • the figures only show these folding rollers 2 and 3 in their position during the cleaning process in the cleaning station 1.
  • the arm of the robot can in particular be arranged on the outer end faces of the folding rollers 2, 3, whereby they 1 can be connected to the robot arm via a horizontal axis of rotation.
  • two folding rollers 2, 3 are shown in particular, as they are known for example from the above-mentioned DE 100 11 854 AI as prior art.
  • These two folding rollers 2, 3 are driven by a common friction wheel 6, the outer periphery of which engages the two end faces 12 of the folding rollers 2 and 3, the axis of rotation of the friction wheel 6 being arranged at right angles to the axis of rotation of the folding rollers 2 and 3.
  • the friction wheel 6 is driven in a speed-controlled manner with the aid of the drive device 4 and via the drive shaft 5.
  • the individual folding rollers 2, 3 come into engagement with the friction wheel 6 one after the other.
  • Various cleaning tools 7, preferably in the x, y and z directions, are arranged on the side of the cleaning station 1 opposite the friction wheel 6. In Figure 2, three cleaning tools 7 are shown, which clean the treads 11 from three folding rollers.
  • the scraper or chisel at the front end of the cleaning tools 7 is pressed by pressure regulating valves from the adjusting cylinders 9 with the most constant possible pressing force against the surfaces to be cleaned on the folding rollers 2, 3, so that with the simultaneous rotation of the folding rollers 2, 3 the dirt deposits on the cleaning surfaces are quasi removed by a peeling movement.
  • this mechanical cleaning using a scraper or chisel can be used to carry out cleaning and solvent-free cleaning. Cleaning with a scraper or chisel is more wear-free compared to brush cleaning. In certain cases, a brush can also be used as a replacement or in addition as a cleaning tool.
  • the dirt and cleaning liquids that occur during the cleaning of the folding rollers 2, 3 and also when cleaning tools 7 may be necessary with the help of the scraper 13 are collected with the help of the dirt collecting trough 8 arranged at the cleaning station 1.
  • the cleaning station 1 can be attached to the roll folding system on a stationary support 10 or any console.

Abstract

L'invention concerne un procédé de nettoyage de rouleaux de pliage (2, 3) disposés sur un bras de robot, guidés le long d'un rebord de pliage lors du pliage. Lesdits rouleaux de pliage (2, 3) fixés au bras de robot sont entraînés en rotation dans une station de nettoyage (1) à l'aide d'un dispositif d'entraînement (4), et les surfaces de roulement (11) des rouleaux de pliage (2, 3) sont ainsi nettoyées. Selon l'invention, les rouleaux de pliage (2, 3) sont entraînés par l'intermédiaire d'une roue à friction (6) entrant en prise par l'extérieur.
