Definitions

  • the invention relates to an embossing stamp device for personal documents for simultaneous embossing stamping of the document and a passport photo attached to it, with a two-part embossing tool consisting of stamp and die, the two tool parts of which are guided so as to be movable relative to one another and at least one of which is attached to a drive device.
  • the object of the invention is to provide an embossing stamp device which allows the stamp image to be perfectly embossed over the entire embossing area, also taking into account surface steps
  • embossing stamp device of the type mentioned at the outset in that at least one of the tool parts in the embossing area has at least two embossing sections which are offset in height by approximately the thickness of the passport photo and which adjoin one another to form a step.
  • Claim 8 protects a novel drive device for the stamping device, which leads to a small size of the device, easy operation and low manufacturing costs.
  • the device can be adjusted with a handle to another material thickness of the photo carrier, for example a thick ID card.
  • the invention further relates to a method for producing a tool part of a two-part embossing tool and it is necessary to provide a simple solution for how the production takes place in order to produce two embossing sections which are at different levels and which produce a uniform embossing stamp image without transition errors.
  • Claim 11 ensures a uniform pressure across the entire stamp area.
  • Claim 12 facilitates the removal of the embossed medium with a very narrow insertion gap.
  • the embossing stamp device 10 has a hydraulic cylinder 12 with a piston and a continuous piston rod 14, to which a die carrier 16 is attached at the bottom and a control plate 18 is attached at the top.
  • the die holder is secured against rotation by means of a bolt 20.
  • a tool part 22, which forms the die and is composed of two segments 24, 26 which are offset in height, is fastened to the die carrier 16.
  • the tool part 22 interacts with a stationary, one-piece tool part 28, which forms the stamp.
  • a gap 30 is formed between the two tool parts 22, 28, into which a document sheet provided with a photo can be inserted.
  • a bolt with stop nut 32 is screwed into the flange of the hydraulic cylinder 12.
  • the control plate 18 strikes the nut 32 in its upward gear and thus defines the height of the gap 30 in the open position of the embossing tool.
  • An electric motor 34 with a reduction gear 36 is used to drive the hydraulic cylinder 12, which screws a spindle 40 of a screw pump 42 via a coupling 38, the pressure line 44 of which is connected to the hydraulic cylinder 12.
  • the clutch 38 consists of two clutch bodies 46, 48, which are fastened to the output shaft of the reduction gear 36 or the spindle 40.
  • the coupling body 48 has a plurality of axially distributed axial bolts 50 which slidably engage in axial guides 52 which are formed by linear ball bearings.
  • a control lever 54 is pivotally mounted about the axis 56 and is preloaded by means of spring 60 in such a way that a probe head 58 which is height-adjustable at the left end (FIG. 1) of the control lever 54 is held in contact with the control plate 18.
  • the control lever 54 is pivoted in the clockwise direction. Thanks to the lever ratio of 5: 1, the control path for the microswitch 62 is approximately 5 mm.
  • the microswitch 62 is actuated and switches off the motor 34.
  • Figures 3 to 5 illustrate the tool part 22, which consists of two segments 24, 26.
  • a corner piece is cut out from a square plate of constant wall thickness, so that the two segments 24, 26 are formed, the corner piece being somewhat larger than a quadrant in the exemplary embodiment.
  • An embossed image 21 is then engraved into the tool part 22 composed of the two segments 24, 26, as in the case of a one-piece die, about 3/4 forming an embossed section 23 in segment 24 and 1/4 forming an embossed section 25 in segment 26.
  • the two segments 24, 26 are now screwed onto the die carrier 16, which is at the bottom, but segment 24 has one underlying intermediate layer 27 is underlaid, the thickness of which is about 0.25 mm and thus approximately corresponds to the thickness of a conventional passport photo. This creates a step 29 between the two segments 24, 26, on which two contact edges 31, 33 lying at right angles to one another are formed for the passport photo.
  • the document sheet with the passport photo is by the in FIG. 1 inserted insertion slot on the left into the gap 30 when the tool part 22 is in the upper open position.
  • the passport photo is then brought to bear on the two contact edges 31, 33, after which the motor 34 is switched on.
  • the screw pump 42 generates the high pressure required for embossing.
  • a pressure switch 64 switches off the motor 34.
  • the motor 34 starts in the opposite direction of rotation and pulls the die holder 16 into the open position, in which the control lever 54 actuates the microswitch 62, so that the motor 34 is switched off again.
  • FIG. 6 shows an alternative suspension of the tool part 22 consisting of the two segments 24, 26 on the die holder 16. Both segments 24, 26 are suspended separately by means of shoulder screws 66 in the direction of movement of the die holder 16. The shoulder screws 66 are guided in bores of the die carrier 16 and screwed into the segments 24, 26 by means of their threaded sections.
  • the intermediate layer 27 of approximately 0.25 mm thickness is located on the rear side of the segment 24 facing the die carrier 16.
  • the heads of the shoulder shoulder screws 66 assigned to the segment 26 rest on compensating rings 68 which are also approximately 0.25 mm thick.
  • the length of the pass school The screw 66 is dimensioned such that between the segments 24, 26 and the die carrier 16 there is space for an elastically deformable plate 70 made of an elastomer with a hardness of about 90 Shore, and a small air gap 72 between the die and the die carrier 16 when the embossing tool is open is formed.
  • the elastic plate 70 compensates for slight differences in thickness between the intermediate layer 27 and the passport photo and ensures a uniform contact pressure over the entire stamp surface. Any parallelism errors of the stamp contact surface in the stamping device 10 are also compensated for.
  • the air gap 72 which forms in the open position of the embossing tool facilitates the removal of the embossed medium, since the gap 30 should only be very small in the interest of an error-free stop formation for the passport photo dodge when the embossed medium is removed.
