Definitions

  • the invention relates to a mechanical roller counter with a ratchet mechanism on the ratchet wheel for the initial roller and incrementing the number rollers according to the preamble of claim 1.
  • Roller counters with mechanical or electromechanical drive are known. These are used to record quantities, parts, quantities, lengths or movements.
  • the output force for the display rollers is transmitted via shafts, levers, gears and the like.
  • Mechanical components In the known electromechanical counters, the driving force is supplied in the form of electrical energy and converted into mechanical energy in the counter for actuating the number rollers, e.g. according to DE-PS 35 11 870, DE-GM 83 30 263 and DE-GM 19 35 240.
  • the invention has for its object to provide a particularly reliable and inexpensive counter with a low overall height, which can be used on site even in extremely unfavorable conditions, such as in plant construction and in hydraulically operated machines is to be driven without contact without electrical connections or electrical energy supply.
  • the counter according to the preamble of claim 1 is characterized in that the rocker carries a permanent magnet on at least one side and is preferably held in the rest position under the action of a holding magnet or ferromagnetic part and / or a spring, such that when approaching of a ferromagnetic or magnetic switching part, the coil-free magnetic rocker tilts while advancing the ratchet wheel and thereby causes the counting without supplying electrical energy.
  • a rocker can be used with permanent magnets on one side and counterweight on the other, as well as a return spring and ferromagnetic switching part or, as preferably described below, the rocker can accommodate permanent magnets on both sides and interact with a ferromagnetic holding and a magnetic switching part.
  • the drive takes place via permanent magnetic fields which do not react negatively to environmental influences such as dirt, liquids, gases, light, noise and vibrations.
  • the permanent magnets are preferably hermetically sealed, the switching part being located, for example, on the piston of a pneumatic cylinder made of non-magnetic material. The material selection from the counter and the auxiliary devices must be coordinated with the magnetic functions.
  • a permanent magnet with an opposite pole arrangement can be provided on both sides symmetrically to the axis of rotation, such that when a switching magnet arranged outside the counter approaches, the one permanent magnet is attracted and the other is repelled, whereby an increased switching force is achieved.
  • the housing 1 serves to accommodate and store the set of rollers, consisting of number rollers 2 with indexing drives 3 and star wheel 4 for the initial roller and the two parallel shafts 5 and 6, and the two end plates 7 and 8.
  • the shaft 9 supports the magnetic rocker 10 with the two to this (10) symmetrically arranged permanent magnets 11 and 12.
  • the rocker 10 is held in the rest position by the shaft 6 as a ferromagnetic part.
  • the pawl 13 engages in the switching star 4.
  • the magnetic rocker 10 When the switching magnet 14 approaches, the magnetic rocker 10 is tilted in accordance with FIG. 2 due to the torque which increases counterclockwise compared to the holding torque.
  • the first half step for switching on is effected by means of the switching pawl 15, while the second switching step occurs when the rocker 10 is tilted back in Rest position when the switching magnet 14 is removed, which means that the starting position for the next sequence of movements is reached.
  • a magnetic yoke 16 can furthermore reduce scatter losses which occur and thus serve to strengthen the magnetic field in the working area.
  • FIG. 3 shows a top view of the open counter and FIG. 4 shows a side view
  • FIG. 5 shows a partial section through the pneumatic drive.
  • the bearing of the roller set 2 to 6 between the plates 7 and 8 with the ends of the shafts 5 and 6 in the perforation 17 and the slot 18 in the housing 1 can be seen.
  • the shoulder 19 running in the direction of the rocker 10 with bar 20 on the housing 1 can be seen, which serves to fix the counter on the pneumatic cylinder 21 by means of anti-magnetic strips 22.
  • the switching magnet 14 for actuating the counter on the piston 23 is arranged between the seals 24.
