Definitions
- the invention relates to a direct printing method and a container treatment machine having the features of the preamble of claims 1 and 12, respectively.
- direct printing methods and container processing machines with a direct print head are increasingly used, in which the containers are printed directly.
- a direct print head can, for example, operate according to the inkjet printing method, wherein individual ink droplets are applied to a container by means of a plurality of printing nozzles.
- the pressure nozzles are usually arranged in one or more parallel nozzle rows and can be controlled individually.
- For flat printing of the container they are rotated, for example, with container receptacles relative to the direct print head, so that a two-dimensional print image is formed in an ink.
- UV-curable printing inks which are cured on the containers by means of a UV light source.
- UV light source usually a UV light source.
- the printing nozzles are cleaned in regular cycles in order to remove already dried printing ink and / or soiling.
- the so-called "spitting” is carried out, in which all printing nozzles of the direct printing head emit pressure ink under high pressure by an increased firing voltage
- a meniscus vacuum is reduced (for example by -15 mbar), that more or less printing ink running out of the nozzles.
- the impurities are flushed out of the nozzles.
- the nozzles can also be wiped off manually with special wipes or automatically with a cleaning device.
- the known cleaning methods during production are possible only with restrictions or the production process must be completely interrupted.
- the object of the present invention is therefore to provide a direct printing method or a container treatment machine for printing on containers, in which the pressure nozzles are less clogged without the ongoing production must be interrupted.
- This object is achieved in a direct printing method for printing a plurality of similar containers having the features of the preamble of claim 1 with the features of the characterizing part, according to the printing of different sub-groups of containers with one and the same print image in a printing ink one another Nozzle group is activated.
- the nozzle row can be designed to be longer overall than the pressure level required for the printed image.
- the inactive pressure nozzles at the edge of the nozzle row therefore no flow of ink takes place and they risk to harden.
- certain printed images with, for example, graphic elements do not require the full resolution of the direct print head. For this purpose, only every second pressure nozzle is activated. The intermediate, deactivated pressure nozzles can harden so easily.
- a different nozzle group is activated in each case for printing different subgroups of the containers with one and the same print image in a printing ink
- the printing nozzles are stressed more uniformly and a regular flow of ink takes place.
- a slight shift of the printed image by an appropriate selection of the printing nozzles in the nozzle row is not perceived by the consumer.
- the print image may be shifted along the nozzle row or, in the case of resolution reduction, may be activated to different nozzle groups of an alternate raster, the print image being only a few Micrometer shifts. This is imperceptible to the consumer and the otherwise inactive pressure nozzles are regularly activated and flushed. Regular rinsing avoids nozzle failure.
- the direct printing process can be carried out with a container treatment machine for printing on containers in a beverage processing plant.
- the container treatment machine may be arranged downstream of a filling installation for filling a product into the containers and / or a capper. However, the container treatment machine can also be connected upstream of the filling process and / or be connected directly downstream of a container production process.
- the direct printing method can be carried out in a control device of the container treatment machine, which controls at least one direct print head with the at least one row of nozzles.
- the containers may be intended to contain drinks, toiletries, pastes, chemical, biological and / or pharmaceutical products.
- the containers may be provided for any flowable or fillable media.
- the containers may be made of plastic, glass or metal, but also hybrid containers with material mixtures are conceivable.
- the containers may be bottles, cans and / or tubes.
- the containers may be mold containers having at least one surface deviating from the rotational symmetry about the container longitudinal axis.
- the mold containers may comprise at least one relief-type surface area.
- the container can be rotated by means of a container receptacle, preferably around its longitudinal axis, in order to generate a flat printed image via the rotational movement.
- the containers can be fed to a single printing station by means of a transport device, the printing station each comprising one or more direct printing heads. It is conceivable here that the transport of the containers during a printing operation stops or is continued continuously.
- the direct print head can operate with a digital or inkjet printing process, in which the printing ink is delivered to the containers by means of the printing nozzles.
- “Inkjet printing process” here can mean that in chambers of a printing nozzle, a sudden increase in pressure via piezo or thermocouples is generated Each print nozzle may be configured to create a pressure point on the container .
- the direct print head may comprise a nozzle plate having at least one row of nozzles with the print nozzles Nozzle row can have a number of pressure nozzles in a range of 100 - 10000, especially in a range of 500-1024.
- the nozzle plate has a plurality of nozzle rows (for example 1-8) arranged parallel to one another, which are arranged in particular parallel to the container axis by the arrangement of the direct print head on the container treatment machine.
- the pressure nozzles may be arranged in a plurality of parallel nozzle rows, which have an offset in the longitudinal direction to one another, which corresponds in particular to a fraction of a distance of two adjacent pressure nozzles of a single nozzle row, in particular half, 1/3 or 1/4 of the distance.
- the direct printing process for several similar direct print heads or similar modules with multiple direct print heads can be performed in parallel, each of which the corresponding nozzle groups are activated.
- a nozzle group may here mean a selection of the pressure nozzles from the at least one nozzle row.
- Each nozzle group may have an offset to the end of the nozzle row, wherein the respective nozzle group is activated via a change of the offset.
- a range of pressure nozzles can be activated from the offset forming the nozzle group.
- the area of the activated pressure nozzles can correspond to the printing height of the printed image. The offset thus changed moves the area of the active pressure nozzles along the row of nozzles. As a result, the pressure nozzles are regularly activated at the edge of the nozzle row.
- the offset can be changed cyclically or statistically. Cyclic here can mean that the offset for the various subgroups of containers within a cycle goes through a period of values.
- the period of values may correspond, for example, to a sawtooth, triangular or sinusoidal curve.
- this can mean that the offset is randomly selected in a value range.
- the nozzle row can be moved between the printing operations by an actuator with an offset opposite to the respective offset offset to compensate for an offset caused by the shift of the printed image on the containers.
- the area of the activated pressure nozzles for all nozzle groups can remain at a constant height with respect to the containers while the area along the nozzle row shifts.
- all print nozzles can be activated despite a consistent print image, so even the pressure nozzles at the ends of the nozzle row do not dry out.
- the printed image on the container does not shift despite the offset.
- the offset and the offset may have the same amount.
- the pressure nozzles of two of the nozzle groups may be arranged alternately in the at least one nozzle row.
- the resolution of the printed image with respect to the spacing of the printing nozzles in the nozzle row can be reduced because, for example, only every second printing nozzle is activated during printing. Due to the reduced printing resolution, printing ink and thus costs can be saved. Due to the fact that the nozzle groups are arranged alternately and are preferably activated alternately during the printing of a respective container group, nevertheless all the printing nozzles are used and are regularly rinsed by the ink flow.
- the offset of the printed image of the two sub-groups then corresponds to the distance between two adjacent printing nozzles, so a few micrometers. It is also conceivable that three or more nozzle groups are arranged alternately in the at least one row of nozzles in order to further reduce the resolution of the printed image and nevertheless to activate all the printing nozzles on a regular basis.
- the ink quantity of each printing nozzle can be determined for a printing operation and from this the nozzle groups can be determined such that all printing nozzles of the at least one nozzle row are cyclically or statistically activated. This activates the print nozzles, taking into account the actual amount of ink dispensed, so that there is a certain amount of ink flow through each print nozzle. This ensures that even those print nozzles are not clogged, otherwise give off a small amount of ink due to the print image.
- the amount of ink necessary for a printing operation can be determined for each printing nozzle by integration of an associated image line or column.
- the associated image row or column may be the area of the printed image printed by this pressure nozzle.
- the print image can be, for example, a file containing a template of the print image, for example as a matrix of gray values.
- determining the amount of ink of each print nozzle can be determined whether a print nozzle during printing still remains inactive or flows through with an insufficient amount of ink, since, for example, a blank strip is provided in the print image.
- the nozzle groups may then be determined such that the area of the unprinted strip for the container subgroups corresponds to each other with other printing nozzles. Cyclic or statistical in this context may have the same meaning as previously described in more detail with respect to the offset.
- the respectively activated nozzle groups can be determined in such a way that for all printing nozzles the quantity of ink averaged over a plurality of printing operations exceeds a threshold value which excludes, in particular, a blockage of a printing nozzle.
- the threshold value can be determined, for example, by laboratory experiments in which the printing nozzles are operated over a predetermined number of printing operations with gradually decreasing ink quantity and the failure of the printing nozzles is determined by means of a test pressure or the like.
- specific boundary conditions may also be taken into account, in particular ambient conditions (such as the dust load) and / or UV scattered light with respect to dose in a predetermined time interval.
- the predetermined number of printing operations may correspond to a specified number of printing operations of the printing nozzles without cleaning operation. If it then comes to a nozzle failure, then the amount of ink used in this step can be based on the threshold.
- the respectively activated nozzle groups can be determined in such a way that the quantity of ink averaged over several printing operations is uniform for all printing nozzles.
- the amount of ink can be integrated and averaged over the printing processes of the various sub-groups of the containers, and based thereon the allocation of the printing nozzles to the respective nozzle groups can be adjusted such that the ink quantity of each printing nozzle is substantially the same.
- Substantially equal here can mean that the ink quantity of each printing nozzle deviates as little as possible from an average over all printing processes.
- the minimum deviation can be optimized, for example, in an optimization loop.
- the at least one row of nozzles for the one printing ink can be arranged in a single direct printing head. Likewise, several rows of nozzles for the one ink can be distributed over several direct print heads.
- the direct print heads can be arranged such that pressure ranges of the nozzle rows at least partially overlap. This allows you to increase the print height regardless of the configuration of the direct print heads.
- the nozzle groups may each include print nozzles across multiple rows of nozzles and direct print heads. It is conceivable, in particular, that in an overlapping region of the printed image, which can be printed by both direct printing heads, that is to say in what is known as stitching, printing nozzles of the two direct printing heads are activated alternately.
- the alternately activated printing nozzles for printing on the overlapping area are assigned to different nozzle groups.
- the invention provides with claim 12, a container treatment machine for printing containers, with at least one direct print head, are arranged on the plurality of printing nozzles for a printing ink in at least one row of nozzles and for printing the container in each case in a printing operation with a printed image in one Printing ink is formed, characterized in that the container treatment machine comprises a control device for the direct print head for performing the method according to one of claims 1-11.

- the control device may comprise a microprocessor, a memory, analog and / or digital interfaces, a keyboard and / or a screen.
- the control device can be connected to the direct print head via control lines.
- a controllable with the controller actuator may be formed for moving the direct print head along the nozzle row.
- the control device can therefore be connected via control lines to the actuator.
- the actuator may comprise an electric motor, a piezo drive, guide elements and / or a transmission.
- the actuator may be formed as a linear motor. It is conceivable that the actuator operates electrically, pneumatically or hydraulically. By the actuator can be compensated by the use of different nozzle groups on the container resulting offset of the printed image.
- the container treatment machine may comprise a plurality of print heads for the one printing ink, on each of which one or more of the nozzle rows are arranged.
- the resolution can be increased.
- the plurality of nozzle rows can be arranged offset from one another.
- the print height can be increased by at least partially overlapping the print areas of the direct print heads.
- the container treatment machine for the one printing ink can comprise exactly one direct printing head, on which the at least one row of nozzles is arranged.

- the control device 13 can be connected via further control lines to the actuators 6 of the embodiments of FIGS. 2, 4-5 to control the offset D.
- FIG. 2 shows a printing station of the container treatment machine 1 from FIG. 1 in a side view. This just performs the direct printing method according to one of the following embodiments or the claims 1-11. Since the above-described direct print heads 5 A - 5 E or their printing stations are substantially identical and differ only on the color of the ink supplied, the structure of the printing station of FIG. 2 and the direct printing method described below applies to all direct print heads 5 A - 5 E of the preceding Fig. 1 alike.
- the container 2 is received in the container receptacle 4 and is rotated about its axis A via a direct drive 7. It is also conceivable that the container receptacle 4 or the container 2 is rotated via a control cam or a central transmission. This is not relevant to the invention itself.
- the printing image 2a is applied to the container 2 by means of the printing nozzles 54 of the direct printing head 5 in an ink.
- the direct print head 5 is formed with a nozzle plate 51, in which the printing nozzles 54 are arranged in at least one row of nozzles, for example two or even more are conceivable.
- the pressure nozzles 54 are formed with piezo or thermocouples that shoot individual ink drops 52 onto the container 2. By the amount or size of the ink droplets 52 of the gray value of each print image can be controlled. It can also be seen that the print image 2a does not fill the full height of the print width of the direct print head 5.
- the direct print head 5 can be moved in the direction H via an actuator 6.
- the direction of travel H is here substantially parallel to the axis A of the container 2.
- the function of the actuator 6 will be explained in more detail below with reference to FIG. 4.
- the printed image 2a can be generated on the container 2 area.

- direct printing heads with different printing inks can also be arranged in the circumferential direction around the container 2, wherein the container 2 with the container holder 4 is rotated about its longitudinal axis and the different printing inks are printed from several sides.
- the printing station or a plurality of such printing stations can be arranged to follow the transport device 3.
- the direct printing method described below can be carried out either individually with a single direct print head 5 or with all direct print heads 5 A - 5 E of FIG. 1 or in any combination or together.
- FIG. 3 shows an embodiment of the direct printing method in an illustration.
- a comparison of the direct print head 5 to the container 2 or to the printed image 2a printed there can be seen.
- the direct print head 5 is shown for a better illustration in a top view of the nozzle plate 51 (applies equally to FIGS. 4 and 5).
- the nozzle plate 51 comprises the two nozzle rows 53a and 53b with the pressure nozzles 54.
- the two nozzle rows 53a and 53b have an offset in the longitudinal direction to each other, which corresponds to half the distance between two adjacent pressure nozzles 54 in the nozzle row 53a.
- the nozzle rows 53a and 53b have the same nozzle pitch.
- the container 2 shown in FIG. 3 belongs to a subset of a plurality of similar containers, which are printed with the container treatment machine 1 of FIG.
- the print image 2a extends on the container 2 between a lower edge 2c and an upper edge 2b. This results in the pressure level G.
- the lower edge 2c is located at a distance C above the container bottom 2d.
- the print image 2 a has a smaller print height G than the length of the nozzle rows 53 a and 53 b, when printing a first subgroup of the containers 2, only ink from the nozzle group 55 is dispensed.
- This corresponds in length to the pressure level G and comprises the pressure nozzles 54 of the two rows of nozzles 53a, 53b within this height.
- the container type of the container 2 a template for the print image 2a and the desired position, ie the height C, are stored in the control device 13 of the container treatment machine 1 (FIG. 1). Since the position of the direct print head 5 is also stored there, the size A can be calculated from this, which characterizes the distance between the container bottom 2d and the lower end 56 of the nozzle rows 53a, 53b.
- the currently active nozzle group 55 has the offset B opposite to the end 56 of the nozzle row 53a, 53b, which does not correspond exactly to the lower edge 2c of the print image 2a.
- all pressure nozzles 54 of both nozzle rows 53a, 53b are active within the pressure level G.
- the lying in the area E and B pressure nozzles above the nozzle group 55 are initially not active. This is all true for the printing of a first subset of the container. 2
- the offset B ' is chosen to be slightly larger than the offset B, so that the second nozzle group 55' is higher or lower overall.
- the printed image 2a on the container 2 shifts slightly upwards in the case of the printing of the further subgroup, which is not shown here.
- this is imperceptible by the consumer without a concrete comparison of both subgroups.
- this method is advantageous because compared to the nozzle group 55 at the top of the nozzle group 55 ' additional pressure nozzles 54 are activated. As a result, in addition to these pressure nozzles, a regular flow of ink and thus they can clog less easily.
- the offset B is set with a zigzag curve or sawtooth curve between extreme points so far that all printing nozzles 54 of the direct print head 5 are cyclically activated. It is also conceivable that the offset B is changed statistically, ie randomly.
- the different nozzle groups 55 and thus the offset B are determined by determining from the printed image the ink quantity of each printing nozzle 54 for a printing operation. This is done via an integration of the image lines of the print image 2a or a print template. The values of the offset B are now set so that a minimum amount of printing ink is guaranteed for all sub-groups of the container 2. It is also conceivable that the respective activated nozzle groups are determined that for all printing nozzles 54, the average amount of ink over a plurality of printing operations is uniform. As a result, the pressure nozzles 54 are stressed particularly uniformly.
- the printed image 2a is printed with a lower print resolution than the spacing of the nozzles 54 in the nozzle rows 53a, 53b permits.
- the print image 2a can be printed with half the possible print resolution. This means that only the pressure nozzles 54 within the nozzle row 53a are activated for a first subgroup of the containers 2. In a second subgroup of the container 2, the pressure nozzles 54 arranged parallel to the other nozzle row 53b within the pressure level G are activated.
- the printed image 2a is offset by half the distance between two adjacent printing nozzles 54 of a nozzle row 53a, this is barely perceptible by the consumer. This is particularly favorable since the pressure nozzles 54 of both nozzle rows 53a, 53b are claimed despite reduced pressure resolution.
- FIG. 4 another embodiment of the direct printing method is shown in an illustration. This differs from the preceding embodiment in FIG. 3 only in that the direct print head 5 is additionally moved with the actuator 6 in the direction H.
- Previously described features are also possible in this embodiment in any combination. It can be seen that in the printing of the previously described first sub-group of the container 2, the activated nozzle group 55 has the offset B to the end 56 of the nozzle rows 53a and 53b.
- the direct print head 5 is moved from a reference point P 0 by the actuator 6 by an offset D down. Characterized in that the offset B and the offset D have the same amount, a displacement of the printed image 2a on the container 2 is compensated.
- the direct print head 5 is moved in opposite directions by the corresponding offset D, so that the printed image 2a is always at the same height C on the container 2 opposite the container bottom 2d.
- FIGS. 3 and 4 another embodiment of the direct printing method is shown in an illustration. This differs from the preceding embodiments in FIGS. 3 and 4 only in that two offset direct print heads 50a, 50b are used for printing on a container 2 for a greater printing height. Previously described features are also possible in this embodiment in any combination.
- the direct printing module 50 for a printing ink comprises two direct printing heads 50a, 50b which mutually offset in the direction of the printing height G of the printed image 2 and overlap in the region F. Since the direct print heads 50a and 50b each correspond to a direct print head 5 of the preceding embodiments, the possible print height of the print image 2a is approximately doubled. However, the direct print heads 50a and 50b are controlled so that the overlap area 2e of the print image 2a is both printed by half the required amount of ink (stitching).
- the direct print heads 50a, 50b each have two nozzle rows 53aa, 53ab and 53ba, 53bb.
- the nozzle rows 53aa, 53ab and 53ba, 53bb of a direct print head 50a or 50b are also offset from each other in order to increase the resolution.
- the two direct printing methods described with reference to FIGS. 3 and 4 can now likewise be performed with the entire direct printing module 50 in order to displace the nozzle group 55 activated for the printed image 2a by means of the offset B for each container subgroup.
- the printing nozzles are activated regularly at the upper edge of the direct print head 50a or at the lower edge of the direct print head 50b, whereby ink residues are flushed out.
- the entire direct printing module 50 is displaced via the actuator 6 in the direction of the rows of nozzles 53aa, 53ab or 53ba, 53bb in order to compensate for the offset B.
- the printed image 2a on the container 2 always remains at the same height relative to the container bottom. This is particularly advantageous since, regardless of the height of the printed image 2a, all the printing nozzles 54 of the direct printing module 50 are equally cyclically activated.
