REICHENBACHER PEGASUS

Pegasus is an entirely new and unique machine concept for wood processing, based on parallel bar kinematics

Reichenbacher introduced the first functional machine at the end of 2000.

The project has not been further developed to date for a variety of reasons.

Origins:

The principle of linear bar kinematics has been known for many decades. It is based on the fact that 3 bars, which are connected at one end and suspended with linear mobility at the other end, are able to reach the point of intersection of any arbitrary point within a sphere of movement.

Due to the complex calculation of the movement processes and the accordingly extremely high demands on the control, as well as the lack of suitable materials for economical production, no machines or devices existed up to the 1980s, which furthered the research status.

The first systems have been in use in high precision work in the aircraft and automotive industry since the 1990s.

At the end of the 1990s Reichenbacher gave the first considerations to also using this principle in wood processing. Utilised was parallel bar kinematics, whereby 6 bars were used in place of 3. This not only means that every point within the space is reached, but that the position of the platform mounted on the bars is also defined.

Following a comparatively short development phase it was possible to introduce the first functional machine in November 2000.

Advantages:

  • Comparatively low weight of the moving elements
  • Extremely high feed rates and axis acceleration possible
  • Free access to the machine table for the operator on 3 sides of the machine
  • Theoretically very high precision with tolerances in the micrometer range possible with positioning
  • Comparatively low number of parts - therefore low susceptibility to defects
  • Theoretically very large working range with relatively low space requirement. The Z axis movement range in particular can be very large in comparison to conventional machines.
  • The basic design can be flexibly utilised in a wide range of application areas, e.g. workpiece handling, packaging, etc. It is only necessary to exchange the tool for the prototype.

Disadvantages:

  • To date no satisfactory vibration and oscillation damping
  • Economical production not yet possible because no experience with serial production exists to date
  • Systems constructed to date have comparatively large spatial requirements.
  • No cuboid working range, therefore a large portion of the actual working space cannot be used for the majority of applications.
