Definitions

  • the invention relates to a punch operated by alternating current for punching holes in paper, cardboard, pasteboard and the like by means of conventional axially shiftable dies.
  • the object or" the present invention to provide an alternating current punch in which the rectifier is omitted and which enables the apparatus to be connected up directly with the mains supply and thus produce a compact handy aggregate with small switching elements, so that finally all the component parts can be accommodated in a housing cover.
  • the subject matter of the invention is an alternating current punching apparatus for punching holes in paper, cardboard, pasteboard and the like material by means of conventional axially shiftable punching dies using an electromagnet as driving means for these punching dies with direct connection to the mains supply and a feeler lever for initiating the punching operation, and it consists substantially in that the current feed to the electromagnet is effected by the feeler lever through the intermediary of a microswitch and the armature of this electromagnet set in operation thereby actuates a retarding device through another microswitch interrupting the current feed for a predetermined time to allow the removal of the perforated material.
  • the plunger armature in descending presses a piston efiectively cushioned in an air-filled cylinder downwardly through the intermediary of a lever, whereby the air escapes from the cylinder and at the same time the current circuit is interrupted by means of a microswitch connected with this piston while the feeler lever is still in operative position.
  • the removal of the perforated material without friction is effected, according to the invention, by a delayed action through the intermediary of the air cylinder or also on a relay.
  • the armature constructed as a hollow body accom modates in its interior elastic material such as rubber fixed at the bottom end of the hollow body with its free end projecting beyond the lower edge thereof.
  • Punching apparatus constructed according tothe invention ensure that the sheets of paper to be punched can be easily removed after being perforated.
  • the delay action device provided enables the removal to be carried out quickly and also in a reliable manner.
  • the automatic contact-making renders it possible to use one hand for inserting the material to be punched, leaving the other hand free for picking up and preparing further material, and so forth.
  • the apparatus due to the selection of particularly suitable individual elements, is not expensive and unites all the necessary parts in a single housing. Consequently the continuous, unhampered operation which it is sought to attain is rendered possible with the apparatus.
  • FIG. 1 shows the apparatus according to the invention in longitudinal section
  • FIG. 2 is a top plan view of the apparatus without cover.
  • a plunger armature 5 is vertically movable in the solid iron yoke 2 and the coil 3. This armature 5 is drawn into the housing by magnetic force and acts on a one-armed rocker lever 8 pivoted on an axle 7 through the intermediary of a strap 6.
  • Two punching dies 10 interconnected by a cross axle 11 are mounted in bearings 9 in a plate 12 and a plate 12a on the plate 12. They are under the action of a return spring and slide axially.
  • This punching arrangement comprising the parts 8 to 12a is arranged on the yoke 2. Between a hood or dome-like cover 14 and the plate 12a a feed slot 13 is provided for slipping in the material to be punched.
  • this punching arrangement can be removed and exchanged for example for another with different hole spacing and is inaccessibly enclosed by the cover 14.
  • a drawer-like catching box 15 with a handle 16 is provided for the punching waste, which box rests on the base plate 1 and is slidable like a drawer in an aperture provided in the cover 14.
  • a supporting plate with standard marking is also provided on the cover 14.
  • the armature 5 is constructed as a hollow body.
  • the hollow space is filled at its lower end with a solid elastic body, for example of rubber, not shown in the drawing, in such a manner that this body projects downwardly beyond the edge of the hollow body. Consequently, during operation, only the projecting end of the elastic solid body and no metal parts of the hollow body come into contact with the base plate. Thus all disturbing noise is avoided on the impact.
  • At least the one-armed rocker lever 8 and the plate 12a are made from some suitable plastic substance.
  • a push button 24 may be provided on the rear side of the apparatus, which button serves to interrupt the circuit in the case the apparatus, being overloaded due to too much material having been introduced in the feed slot 13.
  • a cushion 25 of any suitable material may be attached to the inside of the cover .14 in such a manner that it lies directly on the rocker lever 8 and the bearings 9.
