Definitions

  • the invention relates to a franking machine, on the franking head of which at least one further printing device is provided in addition to a set of token type wheels.
  • a franking machine is known to make additional impressions on the mailing to be franked in addition to the stamp of the stamp, for example to indicate the type of dispatch, the place of dispatch, the sender and advertising information.
  • the use of an optional printing roller in the franking head of the franking machine allows an easy change between different impressions without manual intervention on the machine. However, this change is also limited to predefined and area-limited impressions.
  • DE-C-29 32 426 describes an example of the drive of such an optional printing roller.
  • advertising impressions which are typically only desired for a limited period, e.g. at a trade fair or to indicate other events, however, it is necessary to replace a printing plate attached to the franking head by hand. This work can hardly be carried out without the hands being at least contaminated by the printing ink.
  • a printing part has also become known from DE-A-3407633, which is simply pushed on and held by spring force.
  • the invention has for its object to find a franking machine that enables simple and quick replacement of a printing plate on the franking head, without there being a risk of contamination for the user or the environment.
  • a franking machine is used to achieve the stated task proposed, which is characterized in accordance with the invention in that a pressure plate is releasably held on the franking head by latching means which can be actuated via a motor drive system.
  • the franking head 1 has a set 5 of stamps type wheels which are adjustable by means of racks 7 guided in the main shaft 6, as is described in more detail in one possible embodiment in US Pat. No. 4,520,725.
  • the franking head 1 carries an optional printing roller 8, a stamp 9 movable in the active position for the type of mailing, and a date printer 10 which can be moved outside of the Franking head 1 arranged drive plunger is adjustable, as described in said US-PS 4,520,725.
  • the above-mentioned, known printing devices 5 and 8, i.e. the movable stamp 5 and the optional printing roller 8, together with a mechanism 11 provided in the franking head 1 for the releasable mounting of the printing plate 3 by a common drive 4 via an overrunning clutch 12, can be adjusted into the desired positions.
  • This setting is made automatically in that the rotary movements of the associated common drive shaft 13 required for the individual positions are reported via two signal disks 14, 15 and these scanning photocells 16, 17 to control electronics for switching the drive 4.
  • the smaller signal disk 15 has only one gap 18 passing through the photocell 17 and rotates only once during two revolutions of the common shaft 13, so that the position changes that occur only after a second revolution of the shaft 13 can be clearly reported back to the control electronics.
  • this smaller signal disk 15 is attached to the same shaft 20, which is driven by the double larger gear 21 of the gear pair 19, 21 to actuate the mechanism 11 for the releasable mounting of the pressure plate 3.
  • eight holes 22 are provided on the circumference of the larger signal disk 14, which pass through the photocell 16 (FIG. 8).
  • gear wheels 19, 23, 24 and a ratchet wheel 30 On the common shaft 13, which runs coaxially with the main shaft 6 of the franking machine, there are three gear wheels 19, 23, 24 and a ratchet wheel 30.
  • the latter secures mechanically exactly by engaging a pressure roller 32 loaded by a spring 37 in its eight recesses 31 the respectively controlled adjustment positions or the rotational positions of these gears 19, 23, 24.
  • a comparable position assurance is provided for the printing positions of the optional printing roller 8, which are on the opposite side of the gear 25 End of the shaft 26 carrying the pressure roller 8 is provided.
  • the gear wheel 19 drives the camshaft 20 of the mechanism 11, which carries two cam bodies 27, 28, for the releasable mounting of the pressure plate 3 via the gear wheel 21.
  • the next larger gear 23 on the common shaft 13 is in engagement with a gear 29 for driving a cam body 38 on a cam shaft 39 for the optional movement of the plunger 9 against the force of a tension spring 40 into a radially outer active position or a radially inner position. non-stamping position.
  • the largest of these coaxial gears 19, 23, 24 is in engagement with an intermediate gear 42 for driving the gear 25 on the shaft 26 of the optional printing roller 8.
  • All of the gears mentioned are mounted on the franking head 1 via their associated shafts 20, 39, 41, 26 and consequently perform a circular movement with its working movement, whereby they do not rotate themselves about their geometric axis.
  • the gearwheels 19, 23, 24 fastened on the shaft 13 do not rotate relative to the franking head 1 when it rotates. This is made possible by the one-way clutch 12 mentioned.
  • the pressure plate 3 is held by two ratchet levers 43, 44 on the circumference of the franking head 1, in that the hooks 45, 46 on the pressure plate 3 engage behind hook projections 47, 48 and 47 ⁇ , 48 ⁇ in pairs.
  • Both pawl levers 43, 44 and 43 ⁇ , 44 ⁇ are held in the pre-tensioned position in engagement with the pressure plate 3 by one of the pawl levers (44) being pretensioned by a tension spring 50 acting on its arm 49 and the other pawl lever 43 with its other arm 51 on its arm 52 underpinned.
  • the hooks 45, 46 are beveled outwards and a corresponding bevel on the underside of the hook projections 47, 48 of the pressure plate 3 allows the latch levers 43, 44 to spring back when the pressure plate comes out of the cassette 54 against the franking head 1 pressed and clicked into place.
  • the pawl levers 43, 44 can also be pivoted back into the release position by the leading cam body 27, in that an arm 55 of the pawl lever 43 which is engaged by the other pawl lever 44 rests on it, so that the other pawl lever 44 is pivoted.
  • the ejection levers 58, 59; 589, 59 Betschist are actuated by the lagging cam body 28. This swivels both ejection levers so far that they press the pressure plate 3 away from the franking head 1 by pressing against its edges 62, 63; 62 ⁇ , 63 ⁇ or corners Push cassette 54 in until it clicks into place.
  • the cassette 54 which optionally accommodates the pressure plate 3, is pushed onto two bolts 64, 65 which are fastened to the housing 29 of the franking machine and run parallel to one another and run parallel to the main shaft 6 of the franking machine and locks in this position by a locking lever 66 in a hook 67 (FIG 3) engages, which is located on an end face of the cassette 54.
  • a locking lever 66 in a hook 67 (FIG 3) engages, which is located on an end face of the cassette 54.
  • One end 69 ⁇ of an ejection lever loaded by a tension spring 68 presses against this end face of the cassette 54, so that the cassette 54 slides outward on the bolts 64, 65 when the locking lever 66 releases the hook 67.
  • the release movement of the locking lever 66 is by triggered an electromagnet 71 against the force of a tension spring 70, for which purpose a hinged anchor plate 72 is formed on the locking lever 66.
  • the position of the locking lever 66 and the ejection lever 69 is reported to the control electronics by photocells 74 and 75, respectively, so that it is ensured that the printing plate 3 is ejected into the cassette 54 only when the cassette is fully engaged. If no cassette is inserted, the signal arm 69 ⁇ is in the light path of the photocell 75 and the light path of the photocell 74 is blocked by the signal disk 66 ⁇ , since in the locked position the light path of the photocell 74 is released by a cutout 66 ⁇ of the signal disk 66 ⁇ .
  • the path of movement of the anchor plunger 76 is one of e.g. two mutually parallel electromagnets 77 through the light path of a photocell, e.g. is arranged coaxially with the photocell 74. If the outer end 76 ⁇ has passed the light path of the photocell, the central control electronics are informed that the anchor plunger 76 has carried out a full lifting movement, so that it has completely pushed the pressure plate 3 out of the cassette 54 and pressed it against the franking head 1 until it latches .
  • the two anchor plungers 76 hit with their head 82 on the end 83, 83' of locking levers 84, 84 'fastened to shafts 87, 88 and each provided twice, thereby pivoting their catch 85, too which the outer part of a hook shoulder 47,48; 47 ⁇ , 48 ⁇ of the pressure plate 3 is locked against the force of a tension spring 86 in the release position.
  • the synchronous effect of the two anchor lifters 76.76 ⁇ for the simultaneous release of all hook attachments 47.48; 47 ⁇ , 48 ⁇ is ensured by fastening the four locking levers 84.84 ⁇ on the shafts 87.88.
  • the shafts 87, 88 also serve for the pivotable mounting of delivery levers 90, which are also arranged in pairs and symmetrically to one another.
  • the pivoting movement of these delivery levers 90 results from the earlier beginning pivoting movement of the latching levers 84, 84 ⁇ also provided in the cassette 54, by the ends 83, 83 ⁇ thereof or a pin attached to them (FIG. 3) on a middle of the delivery levers 90, 90 ⁇ provided point, for example a shoulder 94 hits after the anchor plungers 76, 76 ⁇ have pivoted the lever ends 83.83 ⁇ by a path sufficient to catch the pawls 85 out of engagement with the hook projections 47,48; 47,48 ⁇ of the pressure plate 3 move.
  • Springs 95 hold the respective delivery lever 90 in its starting position, in which its nose 92 finds a stop on the shaft 87, 88.
