Definitions

  • This invention relates to an arrangement for the control of an arbitrary number of punches in punching devices for punched tapes and cards.
  • a tape or the like is fed past a punching head by means of a step mechanism which displaces the tape by one hole division for every stroke of the punch.
  • the punching head usually comprises a stationary punching die and a plurality of punching mandrels cooperating with the die and being actuated according to the selected punching code, for example by impulses from an olfice machine or the like.
  • the punching speed was increased substantially by positively controlling the catch members, in such a manner, that they are moved into their operative position at the beginning of the yoke stroke.
  • the catch members are moved into the immediate vicinity of associated selector magnets, and at the same moment current is caused to flow through the magnets corresponding to the selected mandrels.
  • the said catch members are retained in their operative position during the continued stroke of the yoke, for which stroke only a relatively small energy amount is required.
  • the magnets can be given small dimensions and be mounted in the immediate vicinity of the catch members. As a result thereof the masses are small.
  • the catch members which were not selected return by spring action to their non-operative position while the punching stroke of the yoke is continued.
  • the invention relates to an arrangement for controlling an arbitrary number of punches in a punching device wherein the punches are mounted movably in the axial direction in a frame, and are adapted to cooperate with a corresponding number of actuating members which are in turn selected for punch actuation by energization of a corresponding number of electromagnets.
  • the actuating members are two-armed levers which are mounted rotatably on a shaft in a common yoke adapted to move up and down, in such a manner, that at one extreme of the reciprocation of the yoke the actuating members are mechanically caused to abut against the cores of the electromagnets in question by action of a stop member rigidly mounted in the frame.
  • FIG. 1 is a fragmentary cross-sectional view showing an actuating member in its lowest position wherein it is brought to a definite position abutting a stationary stop and the core of the corresponding electromagnet.
  • FIG. 2 is a view similar to FIG. 1 showing how the electromagnet retains the actuating member which thereby swings into position to operate the punch, and,
  • FIG. 3 shows how the actuating member, when it is not actuated by the electromagnet, swings so that no contact is made with the punch.
  • the structure comprises a plurality of transfer membes 1 (only one illustrated in the drawing) pivotally supported on an axle 2, common to all members 1.
  • This axle 2 is supported in a non-illustrated yoke member to which a reciprocating vertical motion is imparted by a non-illustrated power-driven crank mechanism of a kind well known in itself.
  • the axle 2 thus is arranged to move alternately towards and away from a plurality of vertically disposed punches 3, the punches 3 being represented in the drawing only by the bottom end of a punch 3 interacting with the illustrated member 1.
  • the axle 2 arranged for motion in the longitudinal sense of the punches 3 is shown in FIG.
  • the transfer member 1 may assume either of two different operative positions, dependent on whether the electromagnet 4 has been energized, or not. If the magnet is energized, the transfer member 1 will rock counterclockwise as illustrated in FIG. 2, since the end portion of the transfer member engaging the armature of the electromagnet is retained during the upward motion of axle 2 by the electromagnet, whereby the stem of the transfer member is swung in below the correspond ing punch 3, the abutment surface of said stem striking against the punch and assuming the position illustrated in FIG.
