Definitions
- the invention relates to a method and a device for printing containers made of glass, in particular bottles, and a corresponding container.
- Glass bottles are known to be used for filling beverages and are exposed to many influences and stresses both in production processes and during transport and use, which can negatively affect the quality and condition of the glass bottles. Examples of this are mechanical stresses resulting in abrasion, scratches or the like, as well as chemical and thermal influences. In order to keep glass wear and tear to a minimum, it is therefore customary to apply protective layers directly after the bottle has been manufactured.
- a hot finish is carried out at temperatures of around 500 to 700° C., for example by applying tin oxide. This serves to close microcracks and increases abrasion resistance.
- the glass bottles After the glass bottles have cooled, they are usually cold-finished at about 150° C., for example by applying polyethylene wax, which further improves the scratch and abrasion resistance.
- a complex pretreatment is therefore often necessary before direct printing in order to achieve the required adhesion and resilience of the printed image, i.e. the applied color layers, on the coating layer resulting after cold-finishing.
- the bottles are flamed and a precursor is added to the flame.
- an SiOx layer is applied to the flamed surface.
- an adhesion promoter a so-called silane coupling agent, is sprayed on. This then reacts in a suitable way with the printing ink. This results in the following layer structure: Glass, SiOx layer, adhesion promoter, printing ink.
- the method is used for printing containers made of glass, in particular bottles, with containers that have been coated and heated by hot end treatment being taken over from a transport line and transferred to a printing machine, with the containers being cooled to a printing temperature in the area of the transport line and/or the printing machine, and the containers in the printing press are provided with a printed image by direct printing.
- the containers consist of a silicate glass and can be provided by a glass machine for the production of hollow glass bodies in a manner that is known in principle.
- the hot-end treatment preferably produces a hot-end treatment layer in the outlet area of the glass machine, for example in the form of at least one metal oxide based on tin, titanium or a similar metal.
- the surfaces produced in this way are relatively rough and stable.
- the printing temperature is preferably 10 to 50°C, in particular 20 to 40°C.
- the containers are preferably transported individually at a distance from one another from an infeed area of the transport path up to the point of direct printing.
- the transport route includes, for example, a conveyor belt and suitable speed control to create distances / gaps between consecutive containers. This avoids scratching the containers during transport.
- Separation means that the containers do not touch during transport and handling.
- the containers are guided and/or held on the transport route, leaving free a lateral wall area provided for the printed image.
- a clamp system with holding devices for the neck and bottom/foot area of the container is suitable for this.
- a transport section based on a long-stator system with actively driven carriages (mover) is also conceivable. Contact between the respective gripper and container can thus be limited to wall areas that are not to be printed, in order to enable transport that is as gentle as possible without scratching the printed areas of the container.
- the containers preferably have at least one rubbing edge/friction edge made of glass, which covers the lateral wall areas of the containers for receiving the printed image when they touch each other. keeps the containers at a distance from one another, or a functionally corresponding rubbing edge / rubbing edge is applied by direct printing. This enables container transport in which the wall areas of the containers provided for or equipped with the printed image do not touch one another and are also protected against contact with guide elements such as railings or the like. In this way, an optically flawless print image can be created and maintained during transport.
- the containers are preferably cooled to the printing temperature in a cooling tunnel.
- the containers can be printed at room temperature, for example, and optionally under mechanically air-conditioned conditions, which simplifies their handling.
- the containers can also be dried in the cooling tunnel.
- Direct printing preferably includes the application of a primer layer, in particular in the form of an adhesion promoter, to a coating layer produced by the hot end coating.
- the printed image is preferably produced by means of inkjet printing, in particular by applying UV-curing inks.
- UV-curing inks can be fixed quickly, specifically and economically using UV pinning lamps, for example based on LEDs. For example, white is printed first, followed by chromatic colors.
- UV lamps e.g. doped with Hg, Fe, Ga
- Curing using LED UV lamps is particularly advantageous.
- different light sources can be combined in one UV lamp, in particular with different radiation power and/or different radiation spectra. In principle, any actinically effective radiation is conceivable for the pinning/curing.
- a primer base coat
- the primer thus ensures good print quality through suitable spreading of the printing inks and can also control the brilliance of the print.
- Direct printing at a printing temperature that is higher than room temperature (20 to 25 °C) can be advantageous, especially with solvent-based printing inks, since the solvent (water) then evaporates more quickly.
- the containers can be moved into the printing machine while still warm and printed there, so that the printing inks/inks dry/cure faster than at room temperature.
- the cooling tunnel can be appropriately controlled to adjust the printing temperature.
- the printing colors/inks are preferably made in such a way that, in addition to good ink spreading on the surface, sufficient adhesion properties are also achieved. This can be achieved, for example, by using adhesion-improving raw materials in the ink.
- the liquids to be filled into the containers, in particular beverages, may have to be pasteurized to preserve them.
- the containers are exposed to high temperatures and humidity.
- the printing colours/inks are preferably made in such a way that they cannot bleed under these conditions and cannot become detached from the container.
- the printing process can be supplemented by applying a primer with an adhesion promoter / a coupling agent (e.g. silane, zirconate, titanate adhesion promoter) in between.
- a primer with an adhesion promoter / a coupling agent (e.g. silane, zirconate, titanate adhesion promoter) in between.
- the hot end coating and the primer can be coordinated in order to optimize the overall adhesion of the printed image.
- the printing colors/inks can have a mechanical protective function, for example by containing waxes or similar additives that make the inks harder or more resilient to mechanical influences overall. Should additional protection be desired, a transparent protective varnish can be applied by inkjet printing for this purpose. The protective varnish can be applied over the entire surface or even partially. This can also be used to create a scuffing edge/friction edge with an appropriate layer thickness.
- Another way to protect the containers is to apply a cold finish after direct printing.
- a corresponding coating can be applied over the whole area or partially, as long as the requirements for the printed image are met.
- Direct printing preferably includes the application of a transparent protective layer to the applied printed image.
- final curing takes place physically, ie by evaporating a solvent, in particular water, of hardening printing inks in the printed image in a drying tunnel, ie only after direct printing has been completed.
- the individually transported containers are preferably combined by machine after the direct printing in bundles and/or by palletizing for multiple transport.
- the method is, for example, part of a method for producing containers, in particular bottles, made of glass, for bottling beverages, the production method involving melt-forming of the containers, their immediately subsequent hot end treatment and the immediately subsequent execution of the method according to at least one of the above and / or embodiments described below.
- a container in particular a bottle, made of glass, comprising: a container body made of a silicate glass, a hot-end coating layer formed thereon and a coating layer applied thereto directly or by means of an adhesion-promoting layer, in particular according to at least one described above and/or below Embodiment of the method according to the invention, printed image applied in direct printing.
- the printed image is to be understood as a label printed directly on the container.
- the device is used for the direct printing of containers, in particular bottles, made of glass, following their hot end treatment and comprises: a printing machine for direct printing on the containers, in particular by means of an ink jet; at least one transport path for, in particular, individualized transport of the hot-end coated containers from an outlet area of a hot-end coating unit to the printing machine; and a cooling tunnel arranged in the area of the transport section for cooling down the containers, which have been heated as a result of the hot end tempering, to a printing temperature for direct printing.
- the device further comprises downstream of the printing machine a drying tunnel for final curing by evaporating a solvent of hardening printing inks/inks and/or a packing machine for combining/grouping the containers for multiple transport in packs and/or on pallets.
- a drying tunnel for final curing by evaporating a solvent of hardening printing inks/inks and/or a packing machine for combining/grouping the containers for multiple transport in packs and/or on pallets.
- the device also includes a pretreatment unit arranged in the area of the transport section and/or the printing machine for preparing a coating layer produced on the containers by the hot end coating by means of plasma treatment and/or flame treatment and/or for spraying on an adhesion-promoting layer in each case for the subsequent direct printing.
- the pretreatment unit is then set up in particular for applying an adhesion-promoting SiOx layer (SiOx coupling agent) by means of an admixed precursor.
- the pretreatment unit could be designed to spray on a primer/adhesion promoter in order to build up a covalent or intermolecular interaction with the printing ink.
- the transport path comprises holders/grippers that are movable in the transport direction for a mouth area and/or bottom area of the container.
- the device is preferably part of a device for producing containers, in particular bottles, from glass, and upstream of this comprises a glass machine for melt-shaping the containers and a subsequent hot-end coating unit for producing a hot-end coating on the containers.
- prefabricated containers can also be supplied to the device in order to print them.
- FIG. 1 shows a schematic plan view of an embodiment of the device
- FIG. 2 shows a schematic side view of a container on the transport route
- Figure 3 is a schematic representation of the direct printing based method
- FIG. 4 shows a schematic representation of the method with direct printing based on solvent-based printing inks.
- the device 1 for the direct printing of containers 2 made of a silicate glass after their hot end treatment comprises a printing machine 3 for the direct printing of a printed image 4 (shown as an example in FIG. 2) (in the sense of a label) on the containers 2 by means of an inkjet, a transport section 5 for transporting the hot-end coated containers 2 individually to the printing machine 3 and a cooling tunnel 6 arranged in the area of the transport section 5 for cooling down the containers 2, which have been heated to an initial temperature TA as a result of the hot-end coating, essentially to a printing temperature TD for the Direct printing, for example at room temperature.
- the transport section 5 is designed for the individual transport of the containers 2 at distances 7 from one another or corresponding gaps in between. This prevents the containers 2 from colliding with one another in the wall areas provided for the printed image 4 and from being mechanically damaged during transport.
- the transport path 5 accepts the containers 2 from a hot-end treatment unit 8 (only indicated schematically), which is arranged in the outlet area of a glass machine 9 for forming the containers 2 .
- the glass machine 9 can work in a manner known in principle for the production of hollow glass using the blow-blow or press-blow method. It is also indicated schematically that the glass machine 9 can be designed as a rotary machine.
- the containers 2 are preferably bottles and consist of a silicate glass. Its hot end treatment is a process that is known in principle and is therefore not explained in detail.
- the decisive factor for the invention is that the containers 2 are transported in a suitable manner, in particular individually, to the printing machine 3 immediately after their hot end treatment and on the way there are cooled from their starting temperature TA (defined in the outlet of the hot end treatment unit 8 and/or in an infeed area 5a of the Transport section 5) to be cooled down to the printing temperature TD.
- their starting temperature TA defined in the outlet of the hot end treatment unit 8 and/or in an infeed area 5a of the Transport section 5
- an additional temperature correction to the printing temperature TD to be carried out immediately before the first publication in the area of the printing press 3 .
- the transport route 5 comprises a conveyor belt 5b, on which the containers 2 preferably stand upright at a distance 7 from one another.
- endlessly circulating transport means with grippers 5c, corresponding long-stator systems or similar transport means are also conceivable.
- the transport direction 5d of the transport route 5 is also shown.
- a floor-free transport or a transport in which the containers 2 are only held in a neck area 2a and/or a bottom/foot area 2b would therefore also be possible in order to free a wall area 2c of the containers 2 provided for the printed image 4 or from contact recess with the grippers 5c. This is indicated schematically in FIG.
- the containers 2 preferably each comprise at least one rubbing edge (scuffing edge) 2d, which can be made of glass, for example, as part of the container body (shown) or can be printed on by direct printing from the printing machine 3 (not shown).
- rubbing edge can be made of glass, for example, as part of the container body (shown) or can be printed on by direct printing from the printing machine 3 (not shown).
- FIG. 1 shows, by way of example, that the printing press 3 can include a plurality of printing units 10 for applying printing inks/inks, intermediate curing units 11 for the printing inks/inks and a final curing unit 12 for the printing inks/inks.
- the intermediate curing units 11 are in the form of so-called UV pinning units and the final curing unit 12 is in the form of UV emitters, which is known in principle.
- the intermediate curing units 11 and the final curing unit 12 are preferably designed for heat drying on the basis of radiant heaters.
- the printing units 10 can, for example, be designed to successively print white ink and colored inks, such as CMYK, in the direction of transport (arrow).
- the intermediate curing units 11 are then used for the respective partial curing of the printing color/ink applied immediately beforehand and promote their spreading to a suitable extent.
- At least one pretreatment unit 13, for example for flame pretreatment or plasma pretreatment of the container 2 and/or a priming unit 14 for applying a functional primer (base coat) in the sense of an adhesion promoter or the like can be arranged.
- the printing machine 3 can also have a printing unit 15 for applying a transparent protective layer (for example a protective lacquer) to the printed image 4 .
- a transparent protective layer for example a protective lacquer
- a drying tunnel 16 can be present downstream of the printing machine 3 and in particular immediately thereafter, in order to dry the printed image 4 on the containers 2 in a suitable manner, in particular as a result of direct printing using solvent-based printing inks/inks. Their complete drying / hardening can be favored or accelerated in this way. This is particularly advantageous if the drying/final curing of such printing inks/inks with the final curing unit 12 (by means of a radiant heater) in the area of the printing press 3 is not possible or only insufficiently possible.
- a packing machine 17 can be present downstream of the printing machine 3 in order to combine the previously isolated containers 2 in bundles 18 and/or on pallets 19 and thus to feed them into a multiple transport.
- the method 21 according to the first embodiment comprises a first step 22 in which the hot-end tempered containers 2 are cooled from the initial temperature TA to the pressure temperature TD, preferably during ongoing transport and while maintaining individual transport at a distance 7 from one another.
- the containers can then be pre-treated in an optional step 23, for example by flame pre-treatment and/or plasma pre-treatment.
- the containers 2 can be coated with a functional primer in the sense of an adhesion promoter.
- the printed image 4 is then printed directly, first in a step 25, in that the basic color white is printed on and intermediately cured/hardened by means of UV pinning.
- the direct printing of the print image 4 is then continued in that the printing inks of a color model, such as CMYK, and optionally so-called spot colors are respectively printed and intermediately cured by means of UV pinning.
- Colored paints applied in this way can have a mechanical protective function for later transport and use of the container 2 against scratching, abrasion or the like.
- a transparent protective layer (protective lacquer) can be printed on in an optional step 27 .
- the protective layer is then preferably also UV-curing.
- a step 28 the final UV curing of the print layers (printed image 4 and optionally protective layer) takes place.
- an organic protective layer could be applied in the sense of a cold finish in step 29 in order to increase the mechanical resistance of the container 2 and the printed image 4.
- FIG. 4 shows a corresponding sequence of the method 31 according to a second embodiment, based on printing inks that harden by evaporating a solvent such as water.
- steps 32, 33 and 34 correspond to steps 22, 23 and 24 of the first embodiment 21, so that no further explanation is required in this regard.
- Steps 35 and 36 also correspond essentially to steps 25 and 26 of the first embodiment 21 with regard to the color design of the printed image 4.
- the intermediate curing that is obligatory in UV direct printing is replaced by an optional heat drying of the respective printing colors/inks by means of infrared radiation (radiant heaters). replaced, as well as the final curing of the printing colors / inks.
- step 37 a transparent protective layer (protective lacquer) is applied.
- step 38 the printed image 4 and/or the protective layer applied immediately before is finally cured. This can be done in a heat tunnel (not shown), for example.
- an organic protective layer could be applied in the sense of a cold finish in a step 39 in order to increase the mechanical resistance of the container 2 and the printed image 4.
- the containers 2 After curing of all printed layers (printed image 4 and optionally protective layer), the containers 2, which are then sufficiently mechanically protected, can be transferred from individual transport to multiple transport in a step 30 (first embodiment 21) or 40 (second embodiment 31). This is done, for example, by combining the containers 2 into bundles 18 and/or on pallets 19.
- the methods 21, 31 described represent a considerable simplification compared to printing methods in which direct printing takes place on containers after their cold end coating. Accordingly, raw materials can be saved and the number of process steps can be reduced. This leads to savings in production time, material and energy costs.
