Definitions

  • a rotary saddle which can be controlled electro-mechanically from the operators side of a paper cutting machine in which rotation of the saddle is effected by a rocking lever which is controlled by a cam disc, one end of the rocking lever bearing on the cam disc while its other end cooperates with a rib of the rotary saddle by means of an adjusting screw.
  • the invention relates to a rotary saddle for paper cutting machines which serves to bring material which has become warped mainly by influences during printing or by moisture, into a correct position relative to a printed image for a cutting operation.
  • a rotary saddle to be controlled from the operators side of the paper cutting machine in that the rotation of the saddle is effected by means of a rocking lever whichis controlled by a cam disc and one end of which bears on the cam disc and whose other end cooperates with the rotary saddle to rotate the same.
  • the cam disc and rocking lever are connected fast to the housing of the rotary saddle for movement therewith.
  • the cam disc has a sector of a circle for automatic adjustment of the saddle to the zero position. When the rocking lever reaches the are over which this sector extends, the saddle is pivoted into the zero position. The are is of a constant curvature, and thereby the rocking lever no longer moves in this region, so that the zero position setting of the saddle is independent of the precise stop of the cam disc.
  • the movement of the rotary saddle is made perceptible by an indicating device which comprises a cable system which is connected operatively to the cam disc and which by means of an indicating mark indicates the angular postion on an appropriate scale of the reading device.
  • the automatic adjustment of the rotary saddle into the zero position is effected by means of a limit switch which is operated when the rocking lever comes into the region of the aforesaid are on the cam disc.
  • FIG. 1 is a side view of a rotary saddle with an indicating device partly broken away;
  • FIG. 2 is a plan view of the rotary saddle partly broken away.
  • FIG. 3 shows the control elements in plan view on an enlarged scale.
  • a rotary saddle 1 is supported for angular movement about a vertical axis 2 in the plane of the machine table 3.
  • This arrangement is conventional.
  • Situated in a fixed saddle housing 4 are a cam disc 5 and a rocking lever 6.
  • the rocking lever 6 is mounted for pivotable movement about a pivot pin 7, and an end 8 of the rocking lever abuts the cam disc 5 while the opposite end 9 accommodates an adjusting screw 10 which bears on a rib 11 of the rotary saddle 1.
  • the cam disc 5 has three different curvature regions, namely the regions 13 and 14 of varying curvature and the region 15 which has a constant curvature extending over a sector covering about 30".
  • the rotary saddle is in a zero position, i.e. a position in which it is aligned parallel to the cutting knife.
  • a switching cam element 17 which, as shown in FIG. 3, comes into engagement with a limit switch 18 when the end 8 of the rocking lever 6 comes into the region of the sector, and then stops the driving motor.
  • This arrangement automatically locates the rotary saddle in the zero position.
  • the motor 16 is energized when the saddle is in an adjusted position, as for example, after a cutting operation, the saddle will automatically return to its zero position.
  • the activation of the motor 16 for the adjustment of the saddle into the desired angular position is then effected in known manner by means of a switch or the like arranged at the operators side of the machine.
  • a cable pulley 19 Connected to the cam disc is a cable pulley 19 which accommodates a cable 20 which is guided over pulleys 21, 22, 23, 24, 25, and whose end 26 is fixed to a spring 27.
  • the spring 27 is fixedly arranged in the housing 28 of an optical measurement indicating device 29, at a hook 30.
  • the cable 20 is provided with an indicator 32 which indicates each angular position of the cutting saddle in continuous succession on an appropriate scale.
  • the desired angular position can also be achieved automatically.
  • This adjustment can be effected, for example, by providing the material to be cut at its edges with cutting marks such as are used in offset printing, scanning these cutting marks photo-electrically and rotating the saddle until opposite marks are in alignment. In this position, the driving motor is then switched off, so that the saddle is then in precisely the correct position relative to the printed image.
  • the saddle is returned in known manner into the end position.
  • a limit switch (not shown) can be operated which activates the motor 16 so that the cam disc rotates until the cam element 17 contacts the limit switch 18, which then deenergizes the motor 16.
  • the apparatus is posisble to rotate the saddle into the correct position relatively to the printed image in a completely automatic manner and, when the cutting sequence has been carried out, to shift the feed saddle to zero position when the end position is reached and before a new paper pile is introduced.
  • a rotary saddle for rotation about an axis, means acting on said saddle and in contact with the cam for rotating the saddle in response to angular movement of the cam, said saddle having a zero position and being rotatable from said zero position to angularly adjusted positions, and means associated with said cam for halting the 4 cam, after the cam is angularly rotated from an adjusted position, in a position in which the saddle is in the zero position.
  • said indicator device includes a ground glass plate, the indicator on said cable passing adjacent said ground glass plate.
