BACKGROUND
1. Technical Field
The present application relates to a device and method for adding information on the outer surface of articles, such as containers in a container filling plant.
2. Background Information
Background information is for informational purposes only and does not necessarily admit that subsequently mentioned information and publications are prior art.
A beverage bottling plant for filling bottles with a liquid beverage filling material can possibly comprise a beverage filling machine, which is often a rotary filling machine, with a plurality of beverage filling positions, each beverage filling position having a beverage filling device for filling bottles with liquid beverage filling material. The filling devices may have an apparatus designed to introduce a predetermined volume of liquid beverage filling material into the interior of bottles to a substantially predetermined level of liquid beverage filling material.
A wide variety of types of filling elements are used in filling machines in beverage bottling or container filling plants for dispensing a liquid product into bottles, cans or similar containers, including but not limited to filling processes that are carried out under counterpressure for the bottling of carbonated beverages. The apparatus designed to introduce a predetermined flow of liquid beverage filling material further comprises an apparatus that is designed to terminate the filling of the beverage bottles upon the liquid beverage filling material reaching the predetermined level in bottles. There may also be provided a conveyer arrangement that is designed to move bottles, for example, from an inspecting machine to the filling machine.
After a filling process has been completed, the filled beverage bottles are transported or conveyed to a closing machine, which is often a rotary closing machine. A revolving or rotary machine comprises a rotor, which revolves around a central, vertical machine axis. There may further be provided a conveyer arrangement configured to transfer filled bottles from the filling machine to the closing station. A transporting or conveying arrangement can utilize transport star wheels as well as linear conveyors. A closing machine closes bottles by applying a closure, such as a screw-top cap or a bottle cork, to a corresponding bottle mouth. Closed bottles are then usually conveyed to an information adding arrangement, wherein information, such as a product name or a manufacturer's information or logo, is applied to a bottle. A closing station and information adding arrangement may be connected by a corresponding conveyer arrangement. Bottles are then sorted and packaged for shipment out of the plant.
Many beverage bottling plants may also possibly comprise a rinsing arrangement or rinsing station to which new, non-return and/or even return bottles are fed, prior to being filled, by a conveyer arrangement, which can be a linear conveyor or a combination of a linear conveyor and a starwheel. Downstream of the rinsing arrangement or rinsing station, in the direction of travel, rinsed bottles are then transported to the beverage filling machine by a second conveyer arrangement that is formed, for example, by one or more starwheels that introduce bottles into the beverage filling machine.
It is a further possibility that a beverage bottling plant for filling bottles with a liquid beverage filling material can be controlled by a central control arrangement, which could be, for example, a computerized control system that monitors and controls the operation of the various stations and mechanisms of the beverage bottling plant.
In some beverage bottling plants, an information adding station comprises devices or machines that work in clocked cycles for the direct imprinting of containers, in particular in the form of glass or plastic bottles, for example to apply information and/or advertising so that it is permanent and cannot be detached from the container. The information adding is generally done either using a screen-printing process or by pad printing.
Containers in terms of the present application are, in at least one possible embodiment, packaging means, in the form of containers, for the most varied types of liquid products and in this case, in at least one possible embodiment of the present application, also bottles or bottle-type containers or cans or can-like containers. Printing inks in terms of the present application are those colors or inks, in at least one possible embodiment, in lightly viscous liquid form that can be processed with print heads that are digitally actuatable and operate according to the ink jet print head principle.
Consequently, print heads in terms of the present application are, in at least one possible embodiment, print heads that have a plurality of print nozzles for discharging the printing ink, for example in at least one row, and that are individually actuatable for discharging the printing ink and, for this purpose, have a print generating element at the respective nozzle opening, for example in the form of an electrode of a piezo element.
Devices for printing containers by using print heads that operate according to the ink jet print head principle and with relative movement between the print heads and the respective containers are known. In the case of a some existing devices, during the printing process the containers are each positioned on a mandrel in the form of a container support. A plurality of print heads are provided distributed about the mandrel, with which print heads, when the mandrel is rotated, a colored printed image, consisting of a plurality of color sets, is applied to the respective container. The mandrels are provided on a rotatably driven transport element, with which, during the printing, the containers are moved on a transport section formed between a container inlet and a container outlet.

DESCRIPTION OF EMBODIMENT OR EMBODIMENTS
In FIGS. 1-3 the reference 1 is given to a device for printing containers 2 in multiple colors on their outer or outside surface and, in this case, in at least one possible embodiment, on a region of the container outside surface that is realized in a rotationally-symmetrical manner with reference to the container axis, for example on a circular cylindrically shaped or frustum-shaped or substantially circular cylindrically shaped or frustum-shaped region of the outer surface of the container.
The containers 2 are supplied to the device 1 by means of a conveyor, identified schematically in the Figures by the reference 3, standing upright, i.e. oriented with their container axes in the vertical or substantially vertical direction and in a single-track container flow in the direction of transport indicated by the arrow T and after they pass a corona tunnel 4 and a separating screw 5 they reach a rotor 7 of the device 1. At the periphery of the rotor 7, which is rotatably driveable about a vertical machine axis MA in the direction of the arrow R, printing stations 8 are formed at regular angular spacings offset about said machine axis, said printing stations comprising in each case substantially a container support 9, in the form of a turntable that is rotatable in a controlled manner about an axis parallel or substantially parallel to the machine axis, a printing group 10 and a device 11 for drying and/or setting the printing ink. Each printing group 10, in the possible embodiment represented, includes four print heads 10.1-10.4 for generating various color sets of a multiple color print or printed image and another print head 10.5 for flat printing or applying a transparent sealing or protective coating, for example a covering finish onto the printed image generated with the print heads 10.1-10.4.
The print heads 10.1-10.4 are digitally actuatable print heads of the ink jet print head type, for example print heads that can be obtained commercially under the reference “XAAR” or “Xaar500.” The print heads 10.1-10.5 each comprise, correspondingly, a housing with a plurality of individually actuatable print nozzles for discharging the printing ink in the distribution and quantity corresponding to the respective printed image or color set on the background to be printed on, i.e. in the present case onto the outer surface of the container to be printed on. The print nozzles, oriented with their axes horizontally or substantially horizontally, are positioned on each print head 10.2-10.5 in at least one row parallel or substantially parallel to the vertical machine axis MA. The discharging of the printing ink is achieved, for example, through corresponding actuation of electrodes or of piezo elements in the print heads 10.1-10.5, for example at an actuating frequency of up to fifty kiloHertz and a relative movement between the respective print head and the surface to be printed of five hundred sixty millimeters per second. The number of print nozzles per print head is, for example, in the range of 500 with a print width of approximately seventy millimeters. The print heads 10.1-10.4 include color printing ink in different colors, namely in yellow, magenta, cyan and black.
As shown in FIGS. 1-3, the print heads 10.1-10.5 of all the printing stations 8 are positioned on a common circular line surrounding the machine axis MA in such a manner that the print heads of all or essentially all the printing groups 10 entrained with the rotating rotor 7 are situated, with reference to the machine axis MA, inside a circular path on which the container supports 9 move. The print nozzles of all or essentially all the print heads 10.1-10.5, consequently, with reference to the machine axis MA, are aligned with their axes constantly or virtually constantly radially outwards such that the discharging of the printing ink onto the containers 2 is supported by the centrifugal force when the rotor 7 is rotating.
The printing group 10 of each printing station 8, as detailed, is realized in a rotating manner with the rotor 7, however, for the print head change, is at the same time pivotable about the machine axis MA in a successive manner or is switchable further in the direction of rotation of the rotor and in opposition to said direction of rotation such that when a container 2 is being printed, each print head 10.1-10.5 can be moved at least once into a printing position in which the relevant print head with its print nozzles is directly adjacent the container 2 standing upright on the container support 9 with a small distance in between (e.g. less than one millimeter). The device 11, which performs the drying of the printing ink through an application of energy or heat and/or UV radiation, is provided about the axis of the respective container support 9 offset by approximately ninety degrees relative to the printing group 10. With the device 1, the devices 11 are positioned on a common circular line surrounding the machine axis MA, the radius of said circular line being identical or substantially identical to the distance between the axes of the container supports 9 and said machine axis MA, in such a manner that in the direction of rotation R of the rotor the respective device 11 is ahead of the associated container support 9.
For the printing, the containers 2 are transferred in each case individually via the transport star 6 to a printing station 8, at which, with a controlled rotational movement of the container support 9 and consequently with a controlled rotational movement of the containers 2 about their container axes, one after the other the color sets forming the color print are printed with the print heads 10.1-10.4 and then the protective coating is applied with the print head 10.5.
In detail, the printing of each container is effected such that, after the transfer to a printing station 8, the color set corresponding to the print head or the final protective coating are printed onto the outer surface of the container with the print heads 10.1-10.5 each switched into the printing position, and during the printing of each color set and possibly also even during the switching further of the printing group 10 by a print head spacing or by a print head, the drying of the applied printing ink is performed by means of the device 11. During each printing step, i.e. during the printing of the respective color set or the applying of the protective coating and the drying of the printing ink or of the protective coating, each container 2 is rotated by three hundred sixty degrees. Each printing step with the drying is effected for example on an angular region of the rotational movement of the rotor 7 of about fifty degrees such that the printing of the containers 2 is completed reliably before the containers 2 reach a container outlet at which they are discharged via a transport star 12 on a conveyor 13. The resetting of the printing groups 10 into the initial position is effected in the angular region of the rotational movement of the rotor 7 between the transport stars 12 and 6. An improved or sharper printed image is achieved through the treatment in the corona tunnel by charging the containers 2 electrostatically on their outer surface.
An optoelectric control system 14 is provided in the direction of rotation R of the rotor directly before the transport star 12, by means of which control system the print on the containers 2, which are moved past said system and are rotated further about the container axis, is checked so that containers with a faulty print can be discharged on the conveyor 13.
FIGS. 4-6 show, in the form of another specific embodiment, a device 1a which only or virtually only differs substantially from the device 1 in that at the individual printing stations 8 instead of the printing groups 10, printing groups 10a are provided that have the print heads 10.1-10.5 at a support 15, which can be switched further for the print head change by rotating about an axis parallel or substantially parallel to the machine axis MA. The print heads 10.1-10.5 are provided distributed at regular angular distances on the periphery of the support 15. The supports 15 are situated, in their turn, inside the path of movement of the container supports 9 such that each print head moved into the printing position, i.e. positioned directly adjacent the container 2 to be printed, is aligned with its print nozzles radially outwards with reference to the machine axis MA. The printing of the containers 2 is effected, in the case of the device 1a, once again onto the angular region of the rotational movement of the rotor 7 between the transport star 6 and the control system 14, the corresponding print head being switched into the printing position for each color set and for the sealing or protective coating. The printing ink or the sealing or protective coating is dried by means of the device 11 during the printing. The respective container 2 is rotated by three hundred sixty degrees during the printing steps (applying the color sets, the sealing or protective coating and the drying).
FIGS. 7 and 8 show, in the form of another embodiment, a device 1b which only or essentially only differs substantially from the device 1 in that instead of the rotor 7, there is provided a transport system 16, which on at least one transport element, which forms a closed loop and is driveable in an endlessly or virtually endlessly circulating manner, has a plurality of printing stations 8 at regular spacings, each with a container support 9, a printing group 10 and a device for drying the printing ink.
The containers 2 are supplied to the device 1a once again via the transport star 3 with the corona tunnel 4 and are transferred in each case individually via the transport start 6 to a printing station 8, with which the respective container 2 is then moved during the printing in the direction of transport TS on the transport section 17 of the transport system 16. The printed containers 2 are forwarded to the conveyor 13 with the transport star 12 that forms a container outlet.
The printing of the containers 2 with the individual printing inks or color sets of the multi-colored print and the applying of the sealing or protective coating is effected analogously to the description given in conjunction with the device 1. For this purpose, the printing groups 10, entrained with the transport system 16 or their print heads 10.1-10.5 are moveable or switchable for the print head change relative to the transport system 16 in the direction of transport TS and in opposition to said direction of transport and are situated on the inside of the loop formed by the transport system 16. The devices 11 of all or essentially all the printing stations 8 are positioned on a common loop line which also intersects the vertical axes of rotation of the container supports 9, the container supports 9 being ahead of the associated device 11 in each case in the direction of transport TS.
In detail, the printing of the containers 2 is effected once again in such a manner that by switching further the print heads 10.1-10.5, the respective color set or the sealing or protective coating are applied, and during the printing process, possibly also still during the switching further of the print heads, the drying of the printing ink and the sealing or protective coating is effected by means of the associated device 11, the respective container with the container support 9 being rotated by three hundred sixty degrees.
FIGS. 10, 11, 12A, 12B, and 12C also show, in the form of another possible embodiment of the present application, a device 1c for printing containers 2 in multiple colors. The device 1c differs from the device 1 in that a plurality of container supports 9 is provided on the periphery of the rotor 7 at regular angular spacings about the vertical machine axis MA, however, said container supports 9 are not components of the printing stations each with independent printing groups.
In the case of the device 1c, one single printing group or unit 18 is in fact provided with a plurality of print head units 18.1-18.5, each unit of which having a plurality of print heads 19, in the possible embodiment represented two print heads in each case. The print heads 19 are realized in the same manner as the print heads 10.1-10.5. Each print head unit 18.1-18.5 or its print heads 19 serve in the manner described in more detail below for simultaneously or substantially simultaneously discharging the color sets of a color associated with the respective print head unit or the sealing or protective coating onto a number of containers 2 corresponding to the number of print heads 19, i.e. in the case of the possible embodiment represented for simultaneously or substantially simultaneously discharging onto two containers 2.
The print head units 18.1-18.5 are also each realized with two devices 20 that can be switched on or off for drying the respective print or the printing ink, for example by the application of energy, e.g. by heating and/or UV light, in each case one device 20 being associated with one print head 19. The print head units 18.1-18.5 with their print heads 19 and their devices 20 are positioned on a common support 21, which can be moved or pivoted back and forth about the machine axis MA by a stroke that corresponds to a machine spacing, as is indicated in one possible embodiment of the present application in FIGS. 12A, 12B, and 12C with the arrows TR1 and TR2. The print unit 18 formed by the print head units 18.1-18.5 and the support 21 is therefore floating. It is situated, with reference to the machine axis MA, inside the path of movement on which the container supports 9 move when the rotor 7 rotates. In addition, the individual print heads 19 are positioned such that they point radially outwards with their print nozzles, each positioned in a row parallel or substantially parallel to the machine axis MA, with reference to said machine axis, such that the discharging of the printing ink is once again supported by the centrifugal force when the rotor 7 is rotating.
The arrangement is also such that the spacing between the print heads 19 on each print head unit 18.1-18.5, but also the spacing between adjacent print heads 19 on print head units 18.1-18.5 following one another in the circumferential direction of the rotor 7 is identical or substantially identical to the angular spacing between two adjacent container supports 9. In addition, the devices 20 in the activated or switched-on state, seen in a top view of the rotor 7, are offset by ninety degrees relative to the print heads and are positioned on a circular line that surrounds the machine axis MA and also intersects the axes of rotation of the container supports in the direction of rotation R of the rotor ahead of the adjacent container support or the container 2 standing upright on said container support in each case. Each print head unit 18.1-18.4 has associated therewith in each case a color set or a color, namely yellow, magenta, cyan or black. The print head unit 18.5 or its print heads 19 serve for discharging or printing the sealing or protective coating.
The print head units 18.1-18.5 are provided following one another in the direction of rotation R of the rotor in order of their reference numbers, i.e. in the direction of rotation R of the rotor the print head unit 18.1 forms the first print head unit of the printing unit 18 and the print head unit 18.5 forms the last print head unit of the printing unit 18.
The multi-colored printing of each container 2 is effected once again in several chronological printing steps in which the printing, i.e. discharging the relevant color set or the sealing or protective coating and the drying is effected with the containers 2 rotating about the container axes, for example rotating about three hundred sixty degrees. The individual printing steps are executed at each container chronologically one after the other by the print head units 18.1-18.5, with each print head unit 18.1-18.5 at two containers simultaneously or substantially simultaneously in each case. During each printing step, the printing unit 18 is entrained in the same direction and in a synchronous or substantially synchronous manner with the rotor 7 (arrow TR1). The devices 20, in this case, are delivered and activated so that the drying of the generated color sets is also effected during each printing step.
After the completion of each printing step and before the introduction of a new printing step, the printing unit 18 is pivoted back, with devices 20 retracted, in opposition to the direction of rotation R of the rotor by the machine spacing into the initial position (arrow TR2), in which then, on account of the rotational movement of the rotor 7, an unprinted container 2 in each case is adjacent the print heads 19 of the print head unit 18.1 and a container 2 in each case that has already been printed in a previous printing step by the print heads 18.1-18.4 is adjacent the print heads 19 of the print head units 18.2-18.5 for another printing step. In the next printing step, the floating printing unit 18 is then entrained again in the same direction and in a synchronous or substantially synchronous manner with the rotational movement of the rotor 7 by the machine spacing (arrow TR1) and after completion of this printing step is pivoted back by the machine spacing into the original position (arrow TR2). The machine spacing, in this case, is twice the spacing between two container supports 9.
The printing of the containers 2 in multiple colors is completed before said containers 2 reach the transport star 12 that forms the container outlet, so that, also in the case of the device 1c, a control system 14, for example an optoelectric control system is provided in the direction of rotation R of the rotor before the transport star 12 for checking the respective print on the containers 2 moved past said system and being rotated at the same time so that containers 2 with missing or faulty print can subsequently be discharged onto the conveyor 13.
FIGS. 13, 14, 15A and 15B show, in the form of another embodiment, a device 1d which differs in the first instance from the device 1c in that instead of the rotor 7 a transport system 16 is provided that forms a closed loop and is driven in an endlessly circulating manner. The container supports 9 are provided on said transport system 16. In addition, at the transport section 17 of the transport system 16 on which the printing of the containers 2 in multiple colors is effected, there is provided a printing unit 18a, which comprises a plurality of print head units, namely a total of six print head units 18.1-18.6, three of which print head units 18.1-18.3 or 18.4-18.6 are positioned in each case on each side of the transport section 17. The transport system 16 has the container supports 9 at regular spacings.
The print head units 18.1-18.6 are realized in the identical manner as described for the device 1c for the print head units 18.1-18.5 used there, i.e. each print head unit 18.1-18.6 has two print heads 19 spaced apart by half the machine spacing and two devices 20 also spaced apart by half the machine spacing. In addition, the print heads 19 and devices 20 of print head units 18.1-18.3 or 18.4-18.6 adjacent one side of the transport section 17 are each spaced apart by half the machine spacing.
The printing unit 18a or the print head units 18.1-18.6 positioned on a support (not shown) are moveable by a drive (not shown) in a synchronous or substantially synchronous manner and in the same direction with the movement of the transport system 16 out of an initial position in the direction of transport TS by the machine spacing and in opposition to the direction of transport TS back into the initial position, said floating movement also being synchronized or substantially synchronized with the movement of the transport system 16 in such a manner that after the movement back into the initial position, each print head 19 with its printing nozzles is once again situated directly opposite or substantially opposite a container support 9 or a container 2 at that location.
The containers 2 to be printed are supplied to the device 1d by means of the conveyor 3 with the corona tunnel 4 and are transferred in each case individually to a container support 9 by means of the transport star 6. Once the containers 2 have been printed on the transport section 17, the printed containers are removed from the container supports 9 by means of the transport star 12 and are forwarded to the conveyor 13.
The printing of the containers 2 is once again executed in several chronological printing steps, in each printing step a number of containers 2 that corresponds to the number of print heads 19 of the print head units 18.1-18.6, i.e. in the case of the device 1d in each case two containers 2 being printed simultaneously or substantially simultaneously with the two different colors associated with the print head units (at the print head units 18.1/18.4, 18.2/18.5) or with the finish that forms the sealing or protective coating and a printing ink (at the print head units 18.3/18.6). During each printing step the print heads 19 of the print head units 18.1-18.6 are adjacent a container 2. The printing is carried out by rotating the containers 2, for example, by three hundred sixty degrees with the devices 20 activated such that the printing ink applied with one print head 19 is dried by the device 20 following said print head in the direction of rotation of the respective container 2 before a printing ink or finish is applied once again in the same printing step by the other print head 19. During each printing step the printing unit 18a is entrained in the same direction and in a synchronous or substantially synchronous manner with the transport unit. At the end of the printing step the printing unit 18a is moved back into the initial position so that in another printing step a print application can then be effected with the print head units 18.1 and 18.4 onto still unprinted containers 2 in each case and a print application can be effected with the print head units 18.2, 18.3 and 18.5, 18.6 onto such containers 2 that have already been printed in a previous printing step with the print head units 18.1, 18.4 or 18.2, 18.5.
Whereas, in the case of the abovementioned devices 1-1 d, the printing of the containers 2 in multiple colors on their container outer surface is effected directly with the printing groups or their print heads, FIGS. 16 and 17 show a device 1e for printing containers 2 in multiple colors in a transfer print. The printing in multiple colors is once again effected on the container outer surface or container outside surface and in this case in one possible embodiment, with regard to the container axis, on a rotationally symmetrically realized region of the container outer surface, for example on a circular cylindrical-shaped or frustum-shaped region of the container outer surface.
By means of a conveyor, which is schematically represented in FIGS. 16 and 17 and identified with the reference 30, the containers 2 are supplied to the device 1e in the direction of transport specified by the arrow T, standing upright and in a single-track container flow, and having passed a corona tunnel 31 provided on the conveyor 30 and a separating screw 32 they reach a rotor or turntable 34 of the device 1e by means of a transport star 33. At the rotor 34 the containers 2 are retained so as to be rotatable about their container axes at container supports provided at that location (not shown) and are moved during the printing with the rotor 34 on a circular transport section. The printed containers are removed from the rotor 34 by a transport star 35 and are forwarded to a conveyor 36.
The printing of the containers 2 in multiple colors is effected by using transfer pads 37, which are provided on the periphery of a transfer drum 38, which is rotatably driveable about the machine axis MA in the direction of rotation R of the rotor but at a speed that is increased compared to the rotational speed of the rotor 34. The transfer pads 37 are provided at the transfer drum 38 so as to be adjustable radially relative to the machine axis MA between a switched-on position located radially further outside and a switched-back position located radially further inside. In addition, the transfer pads 37 are positioned such that they move with their outer face, curved in an arcuate manner about the machine axis MA, inside the circular path of movement of the containers 2 or of the container supports between the transport stars 33 and 35.
A printing group 39 is provided in the direction of rotation R of the rotor 34 or of the transfer drum 38 upstream of the transport star 33, with which printing group the printed image to be discharged onto the container 2 is applied to the outer face of the transfer pad 37. The printing group 39 comprises a plurality of print heads 39.1-39.4 following one another in the direction of rotation R of the rotor for different colors, for example for yellow, magenta, cyan and black or for generating the various color sets.
The print heads 31.1-31.4 are digitally controllable print heads of the ink jet print head type, for example print heads that are commercially available under the name “XAAR” or “Xaar500.” The print heads 31.1-31.4 each comprise accordingly a housing with a plurality of individually actuatable print nozzles or nozzle openings for discharging printing ink in the distribution and quantity corresponding to the respective printed image or color print onto the background to be printed, i.e. in the present case onto the outside surface to be printed of each transfer pad moved past the printing group 39. The printing nozzles positioned with their axes horizontally or substantially horizontally are positioned at each print head 39.1-39.4 in at least one row parallel or substantially parallel to the vertical machine axis MA. The discharging of the printing ink is achieved through corresponding actuation of electrodes or of piezo elements or actuators in the print heads, for example at an actuating frequency up to fifty kiloHertz and a relative movement between the respective print head and the surface of a transfer pad to be printed of about five hundred sixty millimeters per second. The number of print nozzles per print head, for example, is in the range of five hundred with a print width of seventy millimeters. The print heads 39.1-39.4 include printing inks each in different colors, namely yellow, magenta, cyan and black.
In the direction of rotation R of the rotor upstream of the printing group 39 there is a cleaning station 40, for example in the form of a cleaning roller, by means of which any printing ink or ink residue is removed from the print or transfer pad 37 before a new printed image is applied.
At the region of the rotor 34 utilized for printing the containers 2, said region in the possible embodiment represented corresponding to an angular region of approximately one hundred eighty degrees, following the inlet star 33 there is provided a device 41 for applying a finish forming a sealing or protective coating on the respective container print, connecting thereto in the direction of rotation R of the rotor a device 42 for drying the container print, including the sealing and protective coating, for example by application of energy, for example heating or UV light and connecting thereto directly in front of the outlet star 35 an optoelectric control system 43, by means of which the printed containers are checked with regard to the quality of the print whilst rotating about their vertical axes so that wrongly printed containers 2 can then be discharged on the conveyor 36.
In detail, the printing of the containers 2 is effected with the device 1e in such a manner that the containers 2 transferred individually in each case with the inlet star 33 to the rotor 34 or to the container supports at that location are rolled over by the switched-on transfer pads, provided with the printed images on the outer surface, by reason of the transfer drum 38 that rotates somewhat faster compared to the rotor 34, the containers therefore roll off the transfer pads by rotating about their vertical container axes and consequently the printed image is transferred from the respective transfer pad onto a container 2. As the respective transfer pad 37 is still rolling off, that is still inside the transfer region, the containers 2 are moved past the device 41, by means of which the finish that forms the sealing or protective coating is applied to the respective container, rotating about the container axis in a continuous or substantially continuous manner, onto the part of the container print already generated by rolling off the transfer pad 37 on the outer surface of the container.
The devices 41 and 42 and the control system 43 are situated with the rotor 34 in a non-entraining manner on the periphery of the path of movement of the containers 2.
After the completed transfer of the printed image from the transfer pad 37 onto the outer surface of the relevant container 2 or after the completed rolling off of said container on the relevant transfer pad 37 and after the completed applying of the sealing or protective coating, the relevant transfer pad 37 is switched back and the respective container 2, continuing to be rotated about its container axis, is moved past the device 42 for drying the print and past the control system 43 and finally is discharged with the transport star 35 onto the conveyor 36.
After passing the transport star 35, the transfer pads 37 are switched-on once again, i.e. moved radially outwards for the cleaning process at the cleaning station 40 and for the application of a new printed image at the printing group 39.
The treatment of the containers 2 in the corona tunnel 31 and the electrostatic charging of the containers 2 at that location produce a substantial improvement in the multi-color print that is generated with the transfer print onto the outer surfaces of the containers.
In a very schematic representation, FIGS. 18 and 19 show a device 1f that is once again realized for a transfer print in multiple colors on the outer surfaces of containers 2. In the case of this device, the printing of the containers 2 is effected on a transport system 44 that forms a closed loop and is driven in an endlessly or virtually endlessly circulating manner or respectively on a substantially linear transport section 45 of said system. Container supports 46 are provided at regular spacings on the transport system 44. The containers 2 to be printed are supplied to the transport section 45 via the conveyor 30 with the corona tunnel 31 and are transferred individually in each case via the transport star 33 to a container support 46, with which the relevant container 2, retained so as to be rotatable about its container axis, is moved during the printing in the direction of transport TS to the transport star 35, by means of which the printed containers 2 are removed from the transport system 44 and forwarded to the conveyor 36.
For printing the containers 2 in multiple colors, there is a print device 47 provided at the transport section 45 that includes a plurality of transfer elements or transfer pads 48, which are provided at an auxiliary conveyor 49 so as to be rotating with said auxiliary conveyor, said auxiliary conveyor forming a closed loop. The auxiliary conveyor 49 having the transfer pads 48 forms a vertical loop that is provided with its upper horizontally extending loop length 49.1 parallel or substantially parallel to the transport section 45 and directly adjacent or substantially adjacent to said transport section on one side. In their initial position, the transfer pads 48, which, for example, are substantially rectangular and with their longitudinal extension are oriented in the circumferential direction or in the direction of movement of the auxiliary conveyor 49, are positioned with their surface sides in planes perpendicular or substantially perpendicular to the loop plane of the auxiliary conveyor 49.
The auxiliary conveyor 49 is driven in such a manner that its upper length 49.1 moves in the direction of transport TS of the transport section 45, however at a greater speed than the transport section 45.
At the upper length 49.1, following one another in the direction of transport TS there is provided a cleaning station 50 in the form of a cleaning roller for removing printing ink residue on the transfer pads 48 and then a printing group 51. The printing group 51 comprises a plurality of print heads 51.1-51.5 following one another in the direction of transport TS, said print heads being realized, for example, in an identical or substantially identical manner to the print heads 39.1-39.5, however being positioned in such a manner that the print nozzles of said print heads are oriented with their axes in the vertical direction and the rows on each print head formed by the print nozzles are oriented in the horizontal or substantially horizontal direction perpendicularly or substantially perpendicularly or at right angles to the direction of transport TS. The printing group 51, positioned above the path of movement of the transfer pad 48, executes the printing of each transfer pad 46 moved past on the top side positioned in a horizontal or substantially horizontal plane. After the printing each transfer pad 48 is set up such that with its side that has the printed image, it is positioned in a vertical or substantially vertical plane parallel or substantially parallel to the direction of transport TS such that the respective container 2 to be printed, being rotated about its container axis, rolls off a transfer pad 48 and in so doing the printed image is transferred from the transfer pad 48 to the outer surface of the container. At the same time a device 52 applies the sealing or protective coating and a device 53 dries the print.
The device 1f also offers, among other things, the advantage of it being possible to position the print heads of the print group 51 that operate according to the ink jet print head principle in a position that is optimum for the method of operation, namely with their print nozzles above the path of movement of the transfer pads 48 and with the axes of the print nozzles oriented downwards in the vertical or substantially vertical direction.
Once the printed image has been transferred, the relevant transfer pad 48 is pivoted back again into its initial position.
In a very schematic manner, FIGS. 20, 21, 22A, 22B, and 22C show a device 1g that is realized similar to the devices 1, 1a-1d for printing containers 2 in multiple colors on their outer surfaces by applying the printing ink directly onto the outer surface of the container. In the case of this device, the printing is executed on a transport element in the form of a rotor 54, which is rotatably driven about the vertical machine axis (arrow R) and on which are provided container supports 55, offset from one another at regular angular spacings about the vertical machine axis, for the containers 2 standing upright, i.e. with their container axes oriented in the vertical direction. A ring-shaped print head support 56, which is positioned in an axially identical or substantially identical manner to the machine axis, is provided inside the path of movement of the container supports 55, on said print head support in the same spacing or at the same angular spacing that is between the container supports 55, print heads 57.1-57.4 are provided for printing inks in the various colors, namely in yellow (print head 57.1), in magenta (print head 57.2), in cyan (print head 57.3) and black (print head 57.4) along with other print heads 57.5 for applying the coating or protective finish. The print heads 57.1-57.5 are each provided in groups on the print head support 56 in such a manner that each group has the print heads 57.1-57.5 once and the print heads 57.1-57.5 in each group have the same sequence, i.e. for example are provided following one another in the order of their reference numbers in the circumferential direction of the print head support 56, for example in opposition to the direction of rotation R of the rotor 54. The arrangement of the print heads 57.1-57.5 is additionally such that in each printing stage (e.g. positions in FIGS. 22A and 22C) one print head 57.1-57.5 is always or virtually always situated directly opposite or substantially opposite a container 2 or its outside surface in the printing position. In this possible embodiment, the print heads 57.1-57.5 together with the print head support 56 form the printing group 57.
For printing, the containers 2 are once again supplied to the inlet or transport star 6 via the corona tunnel 4 and the separating screw 5 (arrow T) and are transferred in each case individually from said inlet or transport star to a printing station formed by a container support 55. The printed containers 2 are removed at the outlet or transport star 12 and supplied via the conveyor 13 to another use (arrow T).
The container 2 is printed in multiple colors during the transport with the rotor 54 between the inlet star 6 and the outlet star 12. The color sets forming the respective multi-color print and the connecting protective coating are applied in each case one after the other with the print heads 57.1-57.4 or with the print head 57.5 with the containers 2 being rotated or pivoted in a controlled manner about the container axes with the container supports 55, for example with a controlled rotational movement in each case about three hundred sixty degrees.
In detail, the printing of each container 2 is executed such that, after being transferred from the inlet star 6 the container 2 is situated opposite a container support 55 in a first angular region of the rotational movement of the rotor 54, i.e. in a first printing stage it is situated opposite or substantially opposite a print head for generating a first color set, for example the print head 57.1 (FIG. 22A). During this printing stage the print head support 56 is entrained in the same direction and in a synchronous or substantially synchronous manner with the rotor 54. When the color set is applied, the container 2 is rotated in a controlled manner about its vertical container axis by three hundred sixty degrees and at the same time the printing ink applied in each case is dried by means of a suitable device 58 that is associated with each print head 57.1-57.5.
The printing stage for applying another color set or for applying the protective coating that follows the first or in each case another printing stage is introduced by the container support 55 or all or essentially all the print heads 57.1-57.5 being stopped for a short time or being moved by a spacing in opposition to the rotational movement so that the containers “overtake” the print heads 57.1-57.5 by a spacing (distance between the print heads) (FIG. 22B) and thus another print head is situated opposite or substantially opposite each container 2 in a printing position, for example, after the print head 57.1 the print head 57.2, after the print head 57.2 the print head 57.3, after the print head 57.3 the print head 57.4 or after the print head 57.4 the print head 57.5. It is obvious that in each printing stage following a previous printing stage that is effected once again on an angular region of the rotational movement of the rotor 54, the print head support 56 or the print heads 57.2-57.5 are also entrained with the rotor 54 in a synchronous or substantially synchronous manner at the identical or substantially identical speed and in the same direction.
With rotor 54 the printed containers 2 are moved past a hardening or curing station 59 for complete hardening of the printing ink and of the protective coating and then, connected thereto, before reaching the outlet star 12, are moved past a control station or a control system 14, by means of which the print on the container moved past said system and also rotated about its vertical container axis is checked so that any containers with a faulty print can be discharged on the conveyor 13.
In the case of the device 1g, the number of container supports 55 on the rotor 54 is an integer multiple of the number of print heads 57.1-57.5 in each print head group. Accordingly, the angular spacing or spacing between container support 55 in the case of the device 1g is equal to 360°/(n1×n2), wherein n1=number of print heads 57.1-57.5 per print head group, namely for example five n2=number of print head groups on the print head support 56.
It has been assumed above that the print head change between two printing stages following one after the other is effected by slowing down the print head support 56 briefly so that the print heads 57.1-57.5 are “overtaken” by the containers 2. In principle, a print head change is also obviously possible in the reverse manner by briefly accelerating the print head support 56 in each case so that the container supports 55 or the containers 2 are “overtaken” by the print heads 57.1-57.5 during the print head change. In each case, however, the print head support 56 in the printing stage after the print head change and before a new print head change is driven in the same direction and in a synchronous or substantially synchronous manner with the rotor 54.
For reasons of simplicity, the print head support 56 is represented as a ring in FIGS. 20, 21, 22A, 22B, and 22C. In the embodiment of the device 1g in practice, it is possible for said support to have any arbitrary embodiment that can be used for the function. Thus it is possible, in at least one possible embodiment of the present application, to realize the print head support 56, for example, in two parts at least, comprising at least one first element that is entrained with the rotor 54 and at least one other guided element, which is provided at said first element and is switchable further for the respective print head change relative to the first element about the vertical machine axis through stepwise rotation by a spacing (distance between the print heads 57.1-57.5), for example in opposition to the direction of rotation R of the rotor 54 or in said direction of rotation.
The device 1g has, among other things, the advantage that at least the larger part of the angle of the rotational movement of the rotor 54 is available for the printing process, the number of print heads 57.1-57.5 can nevertheless be kept relatively small such that the total number of print heads 57.1-57.5, for example, is equal to the number of container supports 55, and the respective print head change can be effected through short movement strokes.
In the case of the device 1g also, the print heads 57.1-57.2 are positioned once again inside the path of movement of the containers 2 on the rotor 54 so that the applying of the printed images or of their color sets is supported by the centrifugal force of the rotating rotor 54 and print head support 56.
The present application has been described above by way of possible embodiments. It is obvious that numerous changes and variations are possible without departing from the teaching concept underlying the present application.
Thus it has been assumed above that during the printing the containers 2 stand with their container bottom on a container support or on a surface of a rotor or of a transport system. Obviously embodiments are also possible where the containers 2 are retained in another manner during the printing, for example suspended at a container or neck flange provided in the region of the container mouth.
It has also been assumed above that the drying of the respective color set is effected during the printing. In principle, however, it is also possible for the drying not to be effected until the respective color set has been applied to the outer surface of the container.
FIG. 23 shows schematically the main components of one possible embodiment example of what may be a typical system for filling containers, specifically, a beverage bottling plant for filling bottles B with at least one liquid beverage, in accordance with at least one possible embodiment, in which system or plant could possibly be utilized at least one aspect, or several aspects, of the embodiments disclosed herein.
FIG. 23 shows a rinsing arrangement or rinsing station 101, to which the containers, namely bottles B, are fed in the direction of travel as indicated by the arrow A 1, by a first conveyer arrangement 103, which can be a linear conveyor or a combination of a linear conveyor and a starwheel. Downstream of the rinsing arrangement or rinsing station 101, in the direction of travel as indicated by the arrow A 1, the rinsed bottles B are transported to a beverage filling machine 105 by a second conveyer arrangement 104 that is formed, for example, by one or more starwheels that introduce bottles B into the beverage filling machine 105.
The beverage filling machine 105 shown is of a revolving or rotary design, with a rotor 105′, which revolves around a central, vertical machine axis. The rotor 105′ is designed to receive and hold the bottles B for filling at a plurality of filling positions 113 located about the periphery of the rotor 105′. At each of the filling positions 103 is located a filling arrangement 114 having at least one filling device, element, apparatus, or valve. The filling arrangements 114 are designed to introduce a predetermined volume or amount of liquid beverage into the interior of the bottles B to a predetermined or desired level.
The filling arrangements 114 receive the liquid beverage material from a toroidal or annular vessel 117, in which a supply of liquid beverage material is stored under pressure by a gas. The toroidal vessel 117 is a component, for example, of the revolving rotor 105′. The toroidal vessel 117 can be connected by means of a rotary coupling or a coupling that permits rotation. The toroidal vessel 117 is also connected to at least one external reservoir or supply of liquid beverage material by a conduit or supply line. In the embodiment shown in FIG. 23, there are two external supply reservoirs 123 and 124, each of which is configured to store either the same liquid beverage product or different products. These reservoirs 123, 124 are connected to the toroidal or annular vessel 117 by corresponding supply lines, conduits, or arrangements 121 and 122. The external supply reservoirs 123, 124 could be in the form of simple storage tanks, or in the form of liquid beverage product mixers, in at least one possible embodiment.
As well as the more typical filling machines having one toroidal vessel, it is possible that in at least one possible embodiment there could be a second toroidal or annular vessel which contains a second product. In this case, each filling arrangement 114 could be connected by separate connections to each of the two toroidal vessels and have two individually-controllable fluid or control valves, so that in each bottle B, the first product or the second product can be filled by means of an appropriate control of the filling product or fluid valves.
Downstream of the beverage filling machine 105, in the direction of travel of the bottles B, there can be a beverage bottle closing arrangement or closing station 106 which closes or caps the bottles B. The beverage bottle closing arrangement or closing station 106 can be connected by a third conveyer arrangement 107 to a beverage bottle labeling arrangement or labeling station 108. The third conveyor arrangement may be formed, for example, by a plurality of starwheels, or may also include a linear conveyor device.
In the illustrated embodiment, the beverage bottle labeling arrangement or labeling station 108 has at least one labeling unit, device, or module, for applying labels to bottles B. In the embodiment shown, the labeling arrangement 108 is connected by a starwheel conveyer structure to three output conveyer arrangements: a first output conveyer arrangement 109, a second output conveyer arrangement 110, and a third output conveyer arrangement 111, all of which convey filled, closed, and labeled bottles B to different locations.
The first output conveyer arrangement 109, in the embodiment shown, is designed to convey bottles B that are filled with a first type of liquid beverage supplied by, for example, the supply reservoir 123. The second output conveyer arrangement 110, in the embodiment shown, is designed to convey bottles B that are filled with a second type of liquid beverage supplied by, for example, the supply reservoir 124. The third output conveyer arrangement 111, in the embodiment shown, is designed to convey incorrectly labeled bottles B. To further explain, the labeling arrangement 108 can comprise at least one beverage bottle inspection or monitoring device that inspects or monitors the location of labels on the bottles B to determine if the labels have been correctly placed or aligned on the bottles B. The third output conveyer arrangement 111 removes any bottles B which have been incorrectly labeled as determined by the inspecting device.
After sorting, bottles B that are ready to be packed can be directed to a packing or packaging station 303 and packaged for shipment out of the plant.
The beverage bottling plant can be controlled by a central control arrangement 112, which could be, for example, computerized control system that monitors and controls the operation of the various stations and mechanisms of the beverage bottling plant.
