Definitions
- the present invention relates to the field of machines for franking and more particularly to franking machines provided with a thermal printing device.
- Print head of these machines conventionally comprises several printing elements thermal arranged in line transverse to the direction of movement mail items and the implementation of which is carried out by control means according to a heating cycle determined according to the postal imprint to be printed. To allow this printing, a ribbon of thermal transfer is interposed between these printing elements and the article of mail on which the postal imprint must be affixed.
- Thermal transfer ribbon is mounted in a cartridge consumable which is debited as the articles progress of mail, which requires the use of means of training and means for synchronizing the rotation of the ribbon with the advance of the mail items. Given the monetary value attached to the postal imprint, these various means must be particularly reliable.
- the object of the present invention is to overcome the numerous problems posed by the implementation of the thermal transfer ribbon in conventional franking machines by proposing a process thermal printing whose reliability is greatly improved.
- a goal of the invention is to be able to implement this method from a traditional postage meter.
- Another object of the invention is further ensure consistent print quality over time.
- thermo printing process of a postal imprint on a mail item using a mailing machine franking provided with a thermal printing head process in which first passes a pre-deposited heat-sensitive recording medium on at least a specific part of the mail item to franking in front of thermal printing elements of the head thermal printing, then we put in intimate contact the support the printing elements and then order selectively heating these thermal printing elements to print the postal imprint on this recording medium thermosensitive.
- the mail item is further coated the mail item freed from a coating composition.
- the present invention also relates to a franking machine comprising a thermal print head provided with a plurality selectively heatable thermal printing elements and means for pressing a support against the printing elements of heat-sensitive recording pre-deposited on at least part of the mail item to be franked, in order to print a postal imprint.
- the franking machine further comprises a wetting / gluing module to stick the printed label on the postage item to be franked into the machine separately preferably postage by a second transport route for articles of mail.
- the invention also relates to any mail item, in particular an envelope, provided at least in part with a recording medium thermosensitive non-printed and intended for the implementation of the printing process thermal according to the invention.
- such a machine comprises a chassis 10 articulated in two parts, an upper part and a lower part, between which is defined a horizontal path 12 for transporting mail items 14.
- a horizontal path 12 for transporting mail items 14 Along this path are at least arranged at the input of the first rolls of transport or drive 16 and at the output of the second rollers transport or drive 18.
- One or more series of rollers intermediaries can also be planned on this path between the input and output rollers.
- Each of these rolls is advantageously controlled from a common motor 20.
- these motor rollers are of course associated to madly mounted counter rollers, respectively 22, 24.
- a thermal printing device 26 comprising on the one hand a cassette or removable cartridge 28 containing a thermal transfer ribbon 30 and on the other hand a thermal printing head 32.
- This head comprises conventionally several thermal printing elements arranged in line in a direction transverse to the direction of movement of the articles of mail 14.
- Push means 34 are provided under the print head to contact and ensure sufficient pressure of the ribbon thermal transfer to mail items when printing the postal imprint.
- These thrust means which are controlled in synchronization with printing can consist of a roller printing plate or a printing plate.
- the franking machine can also include a dispenser of labels 36 to allow the franking of packages or articles of mail which because of their thickness could not pass by the way transportation of mail items 12.
- a path 38 of transportation of these labels 40 joined this way of transporting mail items to level of the thermal print head 32 upstream thereof.
- the printing process implemented in the franking machine above uses the technology known as. name of thermal transfer and which consists of depositing by means of a heat source (the head thermal printing 32) of hot-melt ink (present on a outer layer of thermal transfer ribbon 30) on a support synthetic or conventional paper (mail item 14 or label 40 which will then be stuck on the postage package).
- an improved printing method is proposed by what the thermal transfer ribbon (as well as the cassette that incorporates it and all the organs necessary for its training, its guidance, etc.) is purely and simply deleted, the support to be printed being beforehand covered with a heat-sensitive recording material intended to cooperate with the thermal printing head 32 of the franking machine for by heating the postal imprint.
- the impression of this imprint mail is made directly on mail items which can be formed entirely of this heat-sensitive recording material or be simply fitted on a part of them, at the place of printing, of a film of this heat-sensitive recording material reactive to a heat source (see below).
- the heat-sensitive recording material is composed conventionally of a chromogenic substance such as a leuco dye and a chromogenic developer such as a phenolic compound, which react with heat to form a color.
- a chromogenic substance such as a leuco dye
- a chromogenic developer such as a phenolic compound
- French patent application FR 2 575 199 illustrates a coating composition intended to improve resistance to oils, solvents and water from heat-sensitive recording paper. Of even, in the French patent application FR 2 731 181, these are the specific characteristics of the heat-sensitive material which are improved to give it better resistance to UV radiation.
- FIG. 2 shows an exemplary embodiment of an envelope 50 used for implementing the method according to the invention.
- This envelope has an envelope body 52, for example made of paper conventional, on which is pre-deposited during its manufacture (by bonding or any other equivalent process), a longitudinal strip 54 of a length substantially equal to that of the envelope and a width sufficient for printing the postal imprint and possibly a slogan or logo, in the range of 25 to 35 millimeters.
- the band longitudinal comprises the aforementioned heat-sensitive recording material and optionally an additional coating composition such as that described in patent FR 2 575 199.
- the envelope can also be carried out entirely and not only in part from only heat-sensitive recording material and therefore not contain all of conventional paper.
- Figure 1 shows a franking machine using the thermal printing process according to the invention. It has a chassis 60 articulated in two parts, an upper part 62 and a lower part 64, between which is defined a horizontal path 66 for transporting the articles of mail 68. Along this path are arranged several series of rollers transport including at least first drive rollers 70 in input and second drive rollers 72 at output. Each of these rollers is advantageously controlled from a common motor 74. To ensure the delivery of mail items, these motor rollers are of course associated with crazy mounted counter rollers, respectively 76, 78.
- a thermal print head 80 conventionally comprising several thermal printing elements arranged in line in a direction transverse to the direction of movement of mail items is arranged on path 66 for transporting mail items.
- of the pressure means 82 are provided under the print head for placing in close contact with thermal printing elements and material thermosensitive recording.
- the franking machine can also include a dispenser of labels 84 powered by labels 86 preferably self-adhesive formed with the heat-sensitive recording material.
- a module of wetting / bonding 88 is advantageously provided downstream of the head to allow if necessary to moisten the labels and to press-on bonding (at eg exit rollers 72, 78) directly on the mail items introduced into the machine's entry preferably by a second transport route for these articles 90.
- a coating module 92 can be provided at the exit of the franking machine to add this composition coating on the franked mail item in order to improve in particular its resistance to radiation and scratches.
