Definitions

  • the invention relates to a handling module for handling vehicle wheels in a system for surface treatment with at least two gripping units carried by a frame structure, each of which comprises a plurality of pressing elements which can be pressed against one or more mating surfaces of a single vehicle wheel.
  • Alloy wheels of motor vehicles which are commonly referred to as alloy wheels, are coated in surface treatment plants with a powder or other coating material. Subsequently, the coating is baked in an oven. For this, the
  • Vehicle wheels are passed from a coating station to an oven. Also vehicle wheels made of other materials, especially steel wheels, are treated in successive steps. Generally speaking, regardless of their material, vehicle wheels must be transferred from one workstation to another workstation.
  • Gripping units comprises a translation device, by means of which the pressing elements relative to the frame structure with a movement component are movable, which is parallel to the axis of rotation of a gripped vehicle wheel.
  • the relative position of at least one vehicle wheel along its axis of rotation and relative to another vehicle wheel can therefore be changed according to the invention, on the one hand, when it is already received by the handling module.
  • the pressing elements can be brought into a position before receiving a vehicle wheel, the structural irregularities of both the vehicle wheels and the handling module compensates itself, so that all vehicle wheels are largely touched the same contact points of the pressing elements.
  • two or more vehicle wheels of different types can be used with the handling module at the same time, as well as structural differences that are not based on tolerances can be compensated. It is particularly advantageous if the pressing elements by means of the translation device relative to the frame structure are coaxial with the axis of rotation of the gripped vehicle wheel movable. A parallel displacement of the moving vehicle wheel is thus excluded. A parallel displacement of the moving vehicle wheel is particularly undesirable when the vehicle wheels are stored in different work stations at defined distances from each other.
  • a plurality, preferably all, of the gripping units each comprise a translating device. In this way, the axial position of all of a gripping unit recorded vehicle wheels can be changed and adapted to each other.
  • the pressing elements of a first gripping unit are movable independently of the pressing elements of a second gripping unit.
  • the respective axial position of a plurality of vehicle wheels received by the handling device can be adjusted individually.
  • the gripping units are set up in such a way that vehicle grippers gripped by the gripping devices are aligned axially parallel to one another with respect to their axis of rotation. In this way, in a plane to ordered vehicle wheels can be quickly and efficiently absorbed by the handling device.
  • the pressing elements of a gripping unit are each supported by a rod element and designed as anpressteller, which can be pressed with its outer edge against an outer surface of a vehicle wheel. Due to the rod element with the Pressteller is a kind of piston unit formed, so that the position of the Anpresstellers can be adjusted hydraulically, electric motor or pneumatically.
  • a gripping unit For a safe handling of a vehicle wheel, a gripping unit comprises at least three rod elements with Anpressteller. Preferably, there are four such units.
  • the robot-assisted movement of the handling device and the gripping and dispensing a vehicle wheel can be adapted to the respective existing or expected vehicle wheels.
  • the sensor device is set up in such a way that each position of the pressing elements can be detected.
  • each position of the pressing elements can be detected.
  • not only one or a few important positions of the pressing elements can be detected, but rather all positions that can take the pressing elements.
