Definitions

  • the invention relates to a pendulum mechanism for reciprocating machine parts according to the preamble of claim 1, in particular for a printing element carrier of a matrix time printer, which can be moved parallel to the printing abutment in forward and back passes and which is connected to a drive generating rotary movements.
  • pendulum mechanisms are used for the treatment, processing or observation, measurement and the like of objects extending along the pendulum path, with a speed curve with prescribed parameters always having to be observed via the effective path.
  • Another requirement is the path-dependent actuation of the working means, tool or measuring instrument in order to avoid complicated position sensors and control loops.
  • Such a path-dependent system operating at constant speed is required in line printer type matrix printers.
  • the dot-printing elements usually hammer tips or wire tips, lie "horizontally" on a line which runs perpendicular to the direction of the movement of the recording medium through the matrix printer. During the printing, the hammers or wires are moved back and forth on the horizontal line.
  • the dot printing elements are operated at predetermined locations to form a dot on the back of an ink ribbon.
  • the timely and timely actuations determine the quality of the typeface and the performance of the matrix printer, which is tailored to the high volume of information to be printed at the output of an electronic data processing system.
  • cam disks or camshafts are the high demands on their manufacture.
  • positive connections are not suitable for higher speeds.
  • the invention has for its object to convert a rotary movement of the drive into oscillating movements of the machine part or of the pressure element carrier with a number of predetermined parameters without great control effort in a pendulum mechanism of the type referred to, in particular in oscillating movements with a constant speed section.
  • the superposition gear consists of a drive axis emerging from the rotary drive and a universal joint connected to it with an output axis, the drive axis and output axis being at a joint angle, and that the reciprocating movement of the machine part or Pressure element carrier can be generated by means of a crank which is driven by the output axis of the superposition gear and whose push rod is connected to the machine part.
  • the rotary motor only rotates in one direction. Inexpensive, low-noise, low-wear, technically proven, rotating machine elements can be used for the superposition gear.
  • the universal joint consist of a universal joint.
  • the desired straight curve sections can be achieved in particular if the joint angle formed between the drive and driven axes of the universal joint is between 30 degrees and 50 degrees, preferably 40 degrees.
  • Another measure for generating suitable speed images is that the universal joint and the eccentric shaft are set out of phase with one another in their basic position.
  • the kinematics of the movements of the pendulum mechanism can also be improved in that the machine part or pressure element carrier, together with the devices carried by it, can be moved synchronously and in opposite directions to an equally large mass of a counterweight with respect to the phase position.
  • the reciprocating machine part 1 consists of the pressure element carrier 1, which is set into oscillating movements by the drive 2 in the form of the rotary motor 2a.
  • the speeds on the machine part 1 according to FIG. 2 are therefore, without taking into account the superposition gear 3, corresponding to those in the case of a sinusoidal curve shape, ie. H. the speeds periodically approach a maximum and a minimum.
  • the superposition gear 3 (FIGS. 1 and 3) converts the non-uniform speeds into uniform ones.
  • the universal joint 3a (also called universal joint or universal joint) is provided as the superposition gear 3.
  • the drive axis 5 is at the output axis 6 at the joint angle a, which is between 30 degrees and 50 degrees, preferably 40 degrees.
  • the rotary motor 2a drives the drive axis 5 with the movement parameters ⁇ 1 ⁇ 1 , where ⁇ 1 represents the angle of rotation (°) of the drive axis 5 and ⁇ 1 the uniform angular velocity.
  • the ratio of the angular velocities is determined as follows:
  • the universal joint 3a (FIG. 3) has an axis 7 which is driven by the drive axis 5 and which rotates at the rotational speed ⁇ 1 . Due to the articulation angle a, the uniform rotational speed ⁇ 1 is converted into a non-uniform rotational speed o 2 on the axis 8. Depending on the position of the eccentric shaft 4, which is phase-shifted by the crank angle y from the position of the axis 8, uniform speeds result in sections.
  • curve 12 has a remarkably straight and very long path section between points 12a and 12b, which represents a constant speed. In this section, it is particularly advantageous to print with a matrix line printer. Curve 10 comes into consideration for applications which are based on a speed dependent on the feed for the recording medium. As can also be seen, a large number of pairing sizes, consisting of the joint angle a and the crank angle y, can be selected.
  • the pressure abutment 15 being provided on the printer frame 14 in the form of a rotatably mounted printing roller over which the recording medium 16 is guided.
  • the pressure element carrier 1 is connected to the crank 4, which forms part of a crank mechanism 17 which is rotatably supported in bearings 18 and 19.
  • the pressure element carrier 1 is articulated to the crank 4 by means of the first push rod 20.
  • the drive 2 is also superimposed on the printer frame 14 provided rotary bearings 21 and 22.
  • the superposition gear 3 is provided as described.
  • the eccentricity and the phase position of the eccentric shaft 24a is the same as that of the crank 4 with a push rod 20.
  • a parallel movement of the pressure element carrier 1 and the counterweight 23 enables leaf springs 25 and 26 or 27 and 28, on which the pressure element carrier 1 and the counterweight 23 respectively support.
