Definitions
- the invention relates to an apparatus and a method for printing markings on flat mail items according to the preamble of claims 1 and 11.
- Mechanical printers can be used to cancel stamps, although the stamp layout is very limited.
- contactless printing systems in particular inkjet printers, with which high print quality can be achieved and a free design of the stamp layout is possible.
- the advantage of this system is the lower wear compared to mechanical systems.
- the use of printing systems with a free design of the stamp layout is particularly attractive if stamps are to be canceled on one side of a consignment and advertising is to be printed on the same side or on the other side. In such a case, the advertising logos can change from shipment to shipment, so that different customer groups can be addressed depending on the destination.
- the mail items are at a predetermined distance, e.g. of 0.5 mm as quietly as possible past the printheads. It is important that the mail items are conveyed at a predetermined speed synchronized with the control of the print heads.
- the transmission is carried out via conveyor belts arranged in pairs, between which the shipments are frictionally drawn, there is the problem that a differential speed arises between the conveyor belts and the shipments.
- Such a speed of difference has a particularly disadvantageous effect if a uniform marking is to be applied to the mailpieces by means of various print heads which are arranged one behind the other and which print at different times.
- the object of the present invention is therefore to provide a device and a method with which a safe and quiet conveyance of the mail items with a predetermined distance from the print heads is achieved.
- FIG. 1 shows an example of a time correctly executed and a non-coctively executed print by two time-delayed printing heads
- FIG. 2 shows a top view of a device according to the invention
- FIG. 3 shows a side view of a device according to the invention
- Fig. 4 is a detailed representation of the opening time for a thick program
- FIG. 5 shows an embodiment of a suction pressure adjusting device for constant normal force on the mailpiece.
- Fig. 1 shows the differences between correctly timed and incorrectly executed prints by two staggered printing heads. The latter shows an offset of the two printed images against each other. If the printheads are otherwise controlled correctly, such a displacement occurs if there is slippage between the consignment and the conveyor belts used for transport.
- Figures 2 and 3 show a preferred embodiment of a device according to the invention in top and side views.
- a backdrop 1 is arranged so that the mailing 3 conveyed between the cover belt 2 arranged in pairs and the perforated conveyor belt 4 is guided past the print heads 8 at a predetermined distance.
- the printing station 8a also has ink containers 7 and an ink supply system and a cleaning pump, which are not shown in the following.
- the Druckstatione ⁇ are controlled by an electronic magazine. Preferably, two printing stations are used, each station requiring one side of a shipment.
- a light barrier 10 is used to control the start of printing. An incoming shipment triggers the signal for printing via this light barrier.
- the first printhead starts to print.
- the second print head starts printing at different times. The start of printing must be coordinated so that a uniform image is generated.
- the control of the printing process is preferably synchronized with a clock generator, which is driven by the conveyor belt 4.
- the distance from the light barrier 10 to the first print head or to the second print head is converted into a number of cycles. Printing begins when the corresponding number of bars has been reached. this in turn corresponds to a certain way.
- the Druckvorga ⁇ g itself is controlled directly by the clock.
- the print heads are preferably designed as inkjet printers.
- a pixel plate is located in the print heads, in which nozzles 11 are arranged so that a predetermined number of these each produce a pixel on the previous day of printing.
- a linear arrangement of nozzles is preferably used, although matrix or other arrangements are also possible.
- these are spatially offset vertically and arranged at a predetermined angle ⁇ .
- the distance from the light barrier 10 to the respective first nozzles of the respective print head is given to an electronic computer as a delay.
- the computer converts the route into bars.
- the start of printing of the heads can be adjusted by changing the deiays.
- Cover belt 2 and perforated conveyor belt 4 run over rollers 12, between which the device is arranged.
- the rollers 12 close the spread between cover belt 2 and perforated conveyor belt 4.
- the size of the normal force is determined by the spreading of the conveyor belts by the belt. The spreading leads to a separation of the bands. In front of and behind the shipment, the spreading of the conveyor belts is closed by the rollers 12. In addition, the size of the normal force due to the excitation is determined by the distance between these two rollers. Since the device for printing is arranged between the rollers 12, the distance between the rollers is not large enough to guarantee a smooth transmission.
- FIGS. 2 and 3 show a suction trough 5 arranged essentially in the region of the pressure heads. This suction trough extends linearly up to the region of the rollers 12 on both sides of the printing station 6, which is arranged between the rollers 12
- the Saugwa ⁇ ne 5 has an opening which is adapted to the conveyor belts, the cover belt 2 and the perforated conveyor belt 4, so that the mail items are pressed against the conveyor belt 4 by the oppression. This is made possible by the fact that the conveyor belt 4 lies against the backdrop that runs over the suction wall.
- the opening is preferably designed as a perforated plate.
- the suction pan extends longer than the backdrop.
- the opening of the vacuum device ie essentially the suction trough, is adapted to the cover belt and conveyor belt in such a way that mail items are pressed against the perforated belt by the vacuum, but that, if no shipment is in front of the vacuum device, the holes in the perforated conveyor belt are closed he follows
- the U ⁇ terbuchvorrichtu ⁇ g is an increase in the normal force on the
- the driving force is therefore too
- F R j - ⁇ - (F N1 + F N2 F s ), where FS denotes the normal force generated by the negative pressure device.
- the size of the additional normal force is at least one
- FIG. 4 shows a situation in which a thicker consignment is clamped between the perforated conveyor belt here and the cover tape 2.
- the opening of the suction pan is closed by the mail and the cover tape 2.
- an opening key 18 can arise in front of and behind the consignment.
- the cover belt 2 cannot close the wedge 18, as a result of which holes in the conveyor belt F 4 are not covered. This creates a leak that leads to a drop in pressure.
- Fig. 5 shows schematically a Saug réelleei ⁇ stellvorraum for connection to the suction chamber.
- a vacuum is generated at the pump 20 and is kept constant by the vacuum valve 21. If a certain negative pressure is reached, the negative pressure valve opens and air is sucked in via a bypass 22. The vacuum remains constant. If the pressure collapses due to leakage, the bypass 22 is closed. Since a large volume flow is conveyed, there are only slight pressure fluctuations.
- a belt 9 is provided in addition to the conveyor belts already mentioned, in order to additionally press the mail items against the backdrop 1 in the lower part. This is particularly useful if, as can be seen in FIG. 3, the conveyor belts 2 and 4 lie over the print heads.
- the round belt 9 achieves additional calming of the shipment and higher print quality.
- the round belt 9 is preferably coupled to the conveyor belt 4.
