DESCRIPTION:

BRIEF SUMMARY
The invention relates to a device for the triggering of a postage meter machine according to the preamble of claim 1.
Postage meter machines are presently used worldwide and are therefore well known. A description of such a machine can be found, for example, in Hasler Review 11 (1978), No. 1, 2-7, R. Grunig, "Hasler Mailmaster F204 Franking Machine".
This is shown in:
FIG. 1 a schematic side elevational view of a postage meter machine modularly formed of a drive unit, a franking unit, and a feed apparatus,
FIG. 2 a copy of an exemplified imprint of a postage meter machine onto a mail piece, in particular onto a letter,
FIG. 3 a schematic view of a block circuit diagram of a drive unit and a franking unit of a postage meter machine,
FIG. 4 a schematic view of a first embodiment of a power connection,
FIG. 5 a schematic view of a second embodiment of a power connection,
FIG. 6 a schematic view of a third embodiment of a power connection.
A postage meter machine 10 is illustrated in FIG. 1 according to this description as state of the art, where the postage meter machine 10 is modularly formed of a drive unit 11, a franking unit 12, and a feed apparatus 13. Added is a collection container 14. The mail pieces 15 to be franked, for example, filled letter envelopes, are disposed as a stack between an insertion wedge 16 and a separator 17. A rotating feed segment 18 pulls consecutively the respective lowest letter toward the right hand side and conveys it to a transport roller pair 19 and to an envelope sealer 20. A infeed roller pair 21 grips the mail piece 15 in the drive unit 11. This mail piece 15 thereby actuates a release fork 22, which is in power connection with a drive, where the drive in turn rotates a print rotor 23 one single time. An inking device 24 inks the print rotor 23 during this rotation, whereupon the print rotor 23 rolls off on the passing letter and thereby places the postage meter stamp. A counter pressure roller 24.1 supports in this case the mail piece 15, independent of the thickness of the mail piece. The letter is then thrown with two discharge rollers 25 into the collection container 14.
An exemplified imprint of a postage meter machine 10 onto a mail piece 15, in particular onto a letter, is illustrated in FIG. 2. The print comprises a value stamp 30, a date stamp 31, and two informative stamps 32, 33. These stamps are to be affixed as a clear print as parallel as possible to the upper edge 115 of the respective mail piece 15, according to the prevailing postal regulations, and they are to be positioned at a favorable distance d from the insertion edge 116. The distance d amounts in case of thin letters, for example, to 10 mm.
As practical use has shown, the distance d varies dependent on the operating speed of the respective postage meter machine 10. If the machine is furnished with a quicker passage than a like constructed, however, slower machine, then the imprint slides towards the left on the envelope, i.e. the distance d becomes larger. The postage meter machines 10 therefore are furnished with an adjustment possibility for adjusting the respectively desired release position of the release fork 22. The recited dependence of the distance d on the operating speed of the respective machine can be quickly balanced and adjusted.
Practical use has further shown that the position and the quality of the value stamp 30 depends on the thickness of the respective mail piece 15.
Therefore, it is an object of the invention to furnish a device, which assures a consistently uniform print quality for any kind of mail piece, i.e., for thin and thick letters, adhesive labels, post cards, and the like.
The solution of this object is given by the characterizing features recited in claim 1. The remaining claims furnish embodiments of the invention. The solution fulfills in this manner the recited object, which object corresponds to an improvement of a correspondingly equipped postage meter machine 10.
The invention is described in the following by way of four additional figures, by way of example.
