Definitions
- the invention relates to methods and devices according to the The preamble of claims 1 and 2 or that of claims 18 and 19th
- Printing on individual objects for example CDs, credit cards, Phonecards and similar objects are made today consistently using processes in which the inks by means of at least one transmission element on the object to be decorated and the transfer element according to the print image to be transferred is designed or with the print image to be transferred is provided.
- a screen printing device act in which the printing ink by means of a squeegee through a template provided with the printed image is applied to the object.
- the second case it becomes common applied the offset printing process, in which the Print ink corresponding to the printed image first on the printing blanket of a cylinder and applied by this to the object becomes.
- the object of the invention is a method and to modify the device of the type described in the introduction, that the production of high quality printed images and high throughput is possible, while at the same time the changeover times can be so short that also very small quantities can be printed economically.
- a solution to this problem can be summarized as follows that for printing on individual objects in particular Process is used in which the to be printed Object along a transport path through at least one Printing station is moved through with a printhead is provided depending on a digital image information containing program is controllable, and the individual nozzles by means of pulse control according to this Program.
- This procedure which is the inkjet process in combination with a digital image information containing program for printing on Can handle individual objects, enables the production of Print images, also multi-color print images, with very good Quality.
- the latter is also due to the fact that Printing on the object during the transport, which is necessary anyway can be done by the printing press.
- the usage a linear motor helps achieve a good one Print quality to a considerable extent, because of the linear motor precise coordination of transport speed and Printing process in the respective printing station.
- the application is thus carried out in both variants of the invention the decoration without contact, so that when there is a change the decoration or the print image to be applied only is required to control the program of each Print head or imaging unit. It is also easily possible to program an object to change to the next object, this change also can be programmed so that, for. B. there is the possibility for example credit cards with a uniform decor too print, however, the card number and the name of the card holder change from card to card.
- the complete Programs for example when moving from one Going to another, it is sufficient that the operator exchanges one program carrier for another, so that Sample prints, if any, are only required in very small numbers will be before normal production starts can.
- the holder for the object can be from the primary part of the linear motor be worn.
- This has the advantage of being present several brackets and thus several transport slides for the simultaneous treatment of several objects in the printing press the movements of the individual Transport sled independently of each other with little effort can be controlled.
- the latter is therefore important because the objects, especially in multi-color printing machines and with it the brackets in the press that carry them go through several stations and in each Stations of different speeds, dwell times etc. may be required.
- the possibility of the individual Mounts or the sled carrying them with respect to their Controlling movements independently of one another helps to achieve this a high throughput.
- the opposite is true Arrangement in which the bracket from the secondary part of the linear motor is not excluded.
- the device shown in Figures 1-3 of the drawing has a transport path 10 which is connected to a rail 11 a linear motor and two parallel guides 12 is.
- a transport path 10 which is connected to a rail 11 a linear motor and two parallel guides 12 is.
- rails 11 and transport track 10 for example, also in the form of a circle, an ellipse or another shape and as an endless transport track running in a horizontal plane be trained.
- the rail 11 two transport carriages 14a, 14b as movable components assigned to the linear motor, the top of each with at least a receptacle 15 for an object 16 to be printed are provided.
- Structure and mode of operation of a linear motor are familiar to the expert, so that they are not explained in more detail here need to be.
- the invention uses the Linear motor drive as a means of transporting the objects through the at least one printing station and, in particular in If there are several printing stations, also for Bridging the distances between the printing stations and between these and any additional handling, Treatment or control stations.
- Each carriage 14a, 14b has two groove-shaped on the underside Provided recesses 19. In each of these recesses 19th engages one of the guide rails 12, which also between Take up rail 11 and slide 14 transverse forces occurring and cause a precise lateral alignment of the carriage.
- the objects 16 are printed in accordance with the embodiment 1 - 3 by means of the inkjet method.
- This is the Device provided with a central computer 18 which the Nozzles 27 (FIG. 3) of the individual inkjet print heads 20 according to controls a program stored in the computer 18, the Object 16 during the printing process along the transport path 19 is moved.
- Each carriage 14a, 14b has at least one provided a non-contact sensor 22, which with a continuous measuring rail 24 of a length measuring system interacts, which runs parallel to the transport track 10.
- the Measuring rail 24 is with 22 triggering in the sensor Measuring points 26 provided at a very short distance from for example, 1 micron are arranged.
- the basic structure of a printhead results from Fig. 3.
- the nozzles 27, from which the printing ink in drop form ejected in the direction of the object 16 to be decorated are arranged in rows above the object in such a way that the distance between two adjacent nozzles 27 one Row of nozzles 29, 30 is not greater than the maximum Diameter of the drop on the object itself forming paint application.
- the number of rows of nozzles and the Arrangement of the nozzles essentially depends on the quality of the printed image, with the general requirement being that seamless printing, i.e. the application of a closed color order must be possible.
- the actuation of the piezo-electrically controlled, for example Nozzles are frequency controlled, with a specific one Pulse sequence results that the program for that in the respective Corresponds to the printing station to be printed image and with the Speed of the object and thus of the slide at Printing process must be synchronized.
- the speed of the sled is controlled via the Frequency of the three-phase current for the linear motor.
- the relative orientation of the object across its transport direction is in the embodiment shown in the drawing performed so that those nozzles of each row of nozzles 29, 30, etc. effective for the respective printing process placed above the area of the object, the one in the respective printing station I or II Order from printing ink is to be provided.
- This is the arrangement taken so that the length of the rows of nozzles is chosen somewhat larger is defined as the width of each print head printing area or section of the object 16. This means that if the area of the object 16 e.g. B. has the maximum width 38, the length of the rows of nozzles 29, 30, etc. is greater than this maximum width 38.
- Es is then proceeded in such a way that, after having camera 36 and Computer 18 the actual position of the object 16 and thus also the Position of the section to be printed has been determined are those nozzles 27 of the existing nozzle rows for the printing process to be effectively put up above of the section to be printed in the area 38 of the same width are located.
- the section of the nozzle series that has been made effective is designated in Fig. 3 of the drawing with 38a.
- sections 38a, 40 and 41 of the respective New row of nozzles must be set. In the result means this means that the section 38a of the activated nozzles 27 each row depending on the location of the object, thus transversely to the transport direction 34, is shifted to the position of the section of the object to be printed adapt.
- the relative alignment of the object and the printhead in the direction of transport 34 takes place after the actual position has been determined the object and comparing it with the target position by calculating the number of pulses for the in general linearn transport route, the deviation of the actual number of pulses from the target pulse number of the deviation from the actual position of the Object from its target position in the transport direction 34 corresponds.
- the size of the drops of paint applied to the object Points about the size of a diameter of e.g. B. 30 - 50 ⁇ lies.
- the distance between two nozzles in a row should not be larger than the maximum diameter of the point formed by the drop of a nozzle Printing ink.
- the number of parallel rows of nozzles in the direction of transport 34 results from the need in If necessary, a covering (closed) layer of paint on the To form object.
- Variable drop sizes of the printing ink can if necessary be achieved by directly from the same nozzle two or more drops are expelled in succession, where then the speed at which the object is advanced, possibly reduced to zero.
- the decoration process works in such a way that first the respective transport carriage 14a, 14b with the object located on it moves under the camera 36 so that the position of the object is determined.
- the Position of the object within the shot will change after that no longer change, because the object z. B. by negative pressure in the Recording is held.
- the camera 36 can in case of need at the same time also used to carry out an identity check to make sure that the right one Object 16 in the receptacle 15 of the transport carriage 14a or 14b is located.
- the actuation of the linear motor happens via a frequency converter 43, which a line 46 is connected to the respective slide 14, and position and / or speed of the carriage 14a by the measuring rail 24 and sensor 22 having measuring system detected and the computer 18 via an information channel 48 are fed in which the position or speed of the carriage 14a is used for this purpose the movement of the carriage and thus of the object 16 to regulate so that the movement with the expiry of Printing process, that is, the actuation of the nozzles 27 of the Printhead 20, is synchronized and so the desired Print image is created, which is often only a Partial print image will act in the sense that there are two more or more such generally different partial print images, each of which is programmed accordingly Printing station is applied in a specific color, too complete a generally multi-colored overall print image. This means that each printing station normally has its own printing program be assigned.
- the line 46 and the information channel 48 can be part of a Form a control loop through which the speed of the respective transport carriage 14a, 14b in particular during the printing process is kept as constant as possible, so far this with the execution of the print program or the frequency of the Printhead can be matched.
- a variable transport speed during the printing process will be applied when the color density is up the object is changed. This is done via the frequency converter 43, in the energy supply of the transport sled and rail 11 formed linear motor switched on is, the speed of the sled over the frequency of the three-phase current is regulated.
- a separate frequency converter is provided is there is the possibility to transport sled independently to control each other in terms of their speed or to regulate.
- the information channel 44 can be used simultaneously information from the respective print head 20 to the computer To give 18.
- Such information can be, for example, the Relate to the nature of the printing ink, for example their temperature and thus their viscosity etc.
- 1 and 2 is a device with two printing stations shown to which a common transport track 10 is assigned is. This means that after the second partial print image in station II on those carried by the carriage 14b Object has been applied, this carriage 14b initially must be moved in the transport direction 34 to To make room for the slide 14a in the printing station II, so that the object in this slide with the second partial print image can be provided. With multi-color printing more than two printing stations are generally provided be different in all printing stations Colors are applied to the object.
- At least one of the printing stations can be a drying station, not shown in the drawing be provided in which the previously applied Partial print image is dried at least so far that when applying the next partial print image, e.g. B. in the Printing station II, there is no longer a risk that the colors both partial print images run into each other or otherwise mix together.
- the measuring rail 24 only in sections in the Provide areas where the printing stations are located are so that the free distances between the linear transport sections or the printing stations by a usual Means of transport can be overcome.
- it is in general especially when using a larger number of transport sledges in combination with a common one Rail should be appropriate to provide a continuous measuring rail, to the movement of the individual sled over the Check the entire length of the transport path and if necessary to be able to control.
- the exemplary embodiment according to FIGS. 4 and 5 is essentially correct Share with those of the embodiment according to the Fig. 1-3 match, so that for the same or corresponding Share also the same, each by 100 higher reference numerals be used.
- the main difference between the two embodiments is that instead of the inkjet printhead is an ionographic Printhead is used and the pattern of each decoration to be applied first in the form of a charge pattern is applied to the object, then Ink in the form of a toner or other suitable Form with the appropriate electrostatically charged Surface is brought into contact. Because the particles of the Toner or any other printing ink one of a latent Pattern representing charge on the surface of the object have opposite charge, they adhere to the charged Areas of the surface to form the respective decoration which can be a partial decoration. The object with the decoration from the printing ink can undergo further treatment to eliminate unnecessary Ink that is also on the unloaded areas may stick to the surface of the object.
- the transport carriage 114a with the object 116 located thereon under the ionographic Station I printhead 120 is transported, which is generally is referred to as a "cartridge".
- the object 116 can be provided with an electrically conductive layer 162, above which there is a dielectric layer 163, whose surface 160 is provided with the charge pattern.
- the electrically conductive layer 162 is via line 168 grounded.
- the electrically conductive layer 162 which is the base electrode in relation to the print head 120, for example with a CD from its metallized coating be formed, with special measures then being taken must be that the CD in the recording 115 or their metallized layer 162 for the purpose of grounding with the Line 168 is conductively connected. The grounding can of course also take place over the transport carriage 114a or 114b.
- the dielectric layer 163 would then be on the CD metallized layer 162 of the CD can be applied.
- a carrier layer 152 At the bottom of a carrier layer 152 is a number of laterally offset high frequency lines 154 arranged over the entire width of the extend to the printerid area.
- the high-frequency lines are used for the purpose of applying the charge pattern those located below the ionographic print head 136, object 116 carried by the transport carriage 114a with a high-frequency AC voltage, the so-called bursts.
- finger electrodes 156 arranged, which are switched so that they depending on the digital image containing information Enable load carrier program or not. charge carrier with the desired polarity shown in Fig.
- the one located at the bottom of the ionographic print head 136 Screen electrode 164 has the function of being created a stream of only charged particles with the desired polarity by establishing the presence of an electric field, which leads to that only ions with the desired polarity the respective Opening 166 towards the one below decorating object to form a latent charge pattern happen.
- the pair of finger electrodes associated with the left opening 166 156 is on so that a current of Load carriers 158 towards the one below Object 116 flows.
- the two finger electrodes 156 in the Opening 166 on the right are switched off, d. that is, applied with such a low voltage that no Flow of charge particles towards the one below Object 116 flows.
- the arrangement of the openings 166 and thus in pairs arranged finger electrodes 156 of the ionographic Printhead 120 corresponds essentially to the arrangement of the Nozzles 27 of the inkjet print head 20, so that even in the embodiment 4 and 6, for example, the relative Alignment between object and printhead 120 through Appropriate activation of those in question Finger electrodes 156 associated with openings 166 is effected.
- the distances between the openings 126 are also or the associated pair of finger electrodes 156 of the print head 120 dimensioned so that if necessary a charge pattern on the dielectric layer of the Object arises, which is a closed, therefore not interrupted job of printing ink leads.
- the ionographic Print station I After the treatment of the object 116 in the the ionographic Print station I having print head 120 becomes the object 116 carrying carriage 114a in the direction of the arrow 134 transported to station Ia, which is immediate is located behind station I.
- station Ia takes place in the usual way of applying the printing ink, for example in Form of a toner, the particles of which on the surface the charge pattern applied to the object is charged in the opposite direction are so that the particles on the surface 160 of the Object 116 stick as soon as this surface in the previously described Way had been charged.
- the Carriage 114a with the object 116 on it into the next station Ib are transported, in which a facility 170 is arranged, which serves excess Color particles and possibly also on the surface of the object to remove remaining charges.
- station II in which also an ionographic Printhead 120 is present in the previously described Applied a second latent pattern to the object, generally an addition to the first latent pattern or the corresponding print image.
- the station II are the stations IIa and IIb in the direction of transport 134 subordinate by the corresponding to the stations Ia and Ib Treatments are carried out.
