Definitions

  • This invention relates to a device in pneumatic cylin­der-piston arrangements in accordance with the introductory portion of claim 1.
  • FIG. 1 designates a cylinder with a cylinder barrel.
  • 2 designates a carrier fastened to a piston running in the barrel of the cylinder 1.
  • the throat portion connecting the carrier 2 with the piston is running in a slot 3 made along the cylinder 1 and covered by a flexible strip 4.
  • This cylinder-piston arrangement is previously known per se and will therefore not be described here more in detail.
  • a breaking roller 5 and 6 is arranged at each end of the cylinder 1.
  • the respective break­ing roller 5 and 6 can be mounted about shafts directly at­tached to the respective end of the cylinder and, thus, sup­ported by the cylinder 1.
  • a flexible endless means in the form of a toothed belt 7 is running over the breaking rollers 5 and 6.
  • two tensioning rollers 8 are arranged, by means of which the tension of the toothed belt 7 can be adjusted.
  • the carrier 2 is fixedly connected to the toothed belt 7 by means of a yoke member 9 or the like, for example screwed to this (indicated at 10). Screws for fasten­ing the yoke member 9 to the carrier 2 are indicated by 11.
  • the breaking roller 5 is further provided with a braking means, for example a magnetic brake 12, by means of which it is possible to brake the roller 5 to stop and consequently also the toothed belt 7.
  • the braking order also adjusts the supply of pressure fluid - compressed air - in such a way that the air supply to the cylinder is also stopped in braking. It is to be understood by this that it is possible to position the carrier 2 anywhere along the cylinder 1 and to lock this in this position.
  • the construction of the magnetic brake as well as its operation by means of electric order signals also actuating the supply of pressure fluid is professional solu­tions and is not intended to be included as a part of the in­vention.
  • the breaking roller 5 can be provided with a detecting element in the form of for example a pulse counter 13, by means of which it is possible to sense the position of the carrier 2 along the cylinder 1. In this way one can deter­mine exactly in advance where the carrier is to stop along the cylinder due to the braking of the roller 5, and it is also possible to introduce automatic control means for the motion of the carrier along the cylinder.
  • the pulse counter is a de­vice known per se and is no part of the invention, either, and therefore a more detailed description of the pulse counter is unnecessary. Instead of the pulse counter for instance a mag­netic tape extending along the cylinder, one or more photo­cells, microswitches etc. can be used as detecting element.
  • breaking rollers 5 and 6 need not be fastened to the cylinder but can of course be attached to other places in the vicinity of the cylinder.
  • break­ing rollers and toothed belt can be built into a casing or rail or be fastened to the cylinder.
