A system (200) for printing on objects (111, 112, 113) and a method (300) for printing on objects (111, 112, 113) are also provided.

Description

Digital printers can be used to print objects of any shape. To do this, a print file is created with the desired image data and scaled to the size and contour of the object. The printer must be informed of the exact position of the object that has been positioned within its print area. For rectangular objects, this is usually done by aligning them with anchor points. For irregularly shaped objects, templates or other aids must be created to help determine the precise position of the object(s) using sensors or other suitable measuring instruments and communicate it to the printer. Such stencils may also need to be used

must first be created in order to be usable for the specific objects.

This results in considerable effort, particularly for individual items, which can extend the actual printing time many times over. Alternatively, cameras are also used to record the position of the objects to be printed. However, especially for large or large-format parts, a large number of cameras must be used in order to limit the system-related distortions. Special image data must then be used

are calculated that include the position and rotation angle of the object.

This takes a considerable amount of time, especially for large objects, as data packets have to be calculated with several gigabytes. Also depends

bump.

If a conventional printing method is used, if there are recesses in the object, e.g. openings or cutouts, the print is simply printed over the free areas and the ink or printing medium lands on the support underneath, e.g. a printing table, a mat or a ribbon. This creates dirt, which in turn gets onto the underside of the following

From DE 102 02 553 A1 and DE 195 25 528 A1 a method for applying paints or varnishes for the color design of object surfaces in building, civil engineering and civil engineering is known, in which the object surface is first recorded as a digital object and a data set is formed. A template of the design object to be applied is then implemented as a digital data record in the recorded data record. Finally, the resulting data set is used to create a movable application device for applying the color or the

From EP 1 839 884 A1 a device for printing decorative images on flat workpieces is known. This includes a printing station with digitally controlled ink application elements, a transport device for transporting the workpieces through the printing station, and a print control that interacts with a digital image data memory and digitally controls the ink application elements for printing digital decorative image data from the image data memory as image points onto the workpiece. The printing station is preceded by a measuring station which records contour data of the workpiece using contour sensors and interacts with the printing control in such a way that pixels of the decorative image lying outside the contour of the workpiece are not printed, while

while the remaining pixels remain unaffected.

The disadvantage of the state of the art is that current processes have efficiency deficiencies. Specifically, scanning the object to be printed and processing the data record takes a lot of time, which means that the system comes to a standstill and thus in-

directly causes costs.

The object of the present invention is therefore to overcome the disadvantages of the prior art, or at least to offer an alternative. This task is solved by the devices or methods according to the independent claims. Advantageous further developments can be found in the dependent claims. An improved device and an improved method are thus achieved.

The printing itself can be effected by moving an object to be printed or by moving the device that applies the respective printing medium. Both methods are generally known. In the first case, the objects could be moved on a conveyor belt under a print head that is parallel to the direction of movement of the objects at right angles!| moved to the support surface of the objects. Alternatively, the objects can be placed on a static surface, e.g. a printing table, and the print head moves on two axes in a plane parallel to the support surface of the object.

The objects are placed anywhere on a printing table or a conveyor belt, i.e. without any particular alignment or orientation. The only thing that needs to be ensured is that no object protrudes beyond the printing table or the conveyor belt. On the one hand, because this could mean leaving the printing area of the print head, and on the other hand, because otherwise the movement of the conveyor belt or

of the print head could be hindered.

According to a first embodiment, a device according to the invention for printing objects is provided. This includes at least one recording device which is set up to record the surface of an object line by line as a printable background. The device further comprises a processing device which is set up to process the printable substrate and create print files. The device further comprises at least one printing device, which is set up to print the object based on the created print files by applying printing means

to print.

The device according to the invention can make the printing process more efficient, because the processing of large amounts of data is avoided by recording the object line by line, processing it line by line to print files and printing accordingly. As a result, after the first line of the object has been recorded, it can be processed immediately by the processing device, while the recording device is already recording the next line. While the recording device records the third line, the processing device can process the second line and create a print file from it. Meanwhile, the printing devices can print the first line from the created print file. So the entire printing process can be essential

In a further embodiment, a system for printing objects is provided. The system includes a device as described above and further a work surface adapted to store the object. The system further includes at least one movement device. These movement devices are set up to either continuously move the object under the receiving device, the printing devices and, if necessary, the drying devices, or

The method according to the invention can make the printing process more efficient, because the processing of large amounts of data is avoided by recording the object line by line, processing it line by line into print files and printing accordingly. This means that after the first line of the object has been recorded, it can be processed immediately while the next line is already being recorded. While the third line is being recorded, the second line can be processed and a print file created from it

The position information chosen in the description, such as top, bottom, side, etc., is also related to the figure directly described and shown and these positions are

reversible, such as stone, concrete, paper, cardboard, cardboard, etc...

In the case of wood, how the device according to the invention works will now be described as an example. The starting material can be, for example, untreated wooden panels, such as cross-laminated wood panels, multi-layer solid wood panels, glued laminated panels or similar panels made of wood or wooden parts, which were prefabricated by a milling machine or saw in a variety of contours and with or without cutouts or openings and placed anywhere on a work surface

210, such as a printing table or other shelf.

In order to recognize the exact positioning of the arbitrarily placed plates, i.e. objects 111, 112 and 113 and their contours, i.e. e.g. corners, curves, openings, cutouts, shapes, etc., and then make the printing information available to the printing devices 140 as a file 131 one or more recording devices 120, also called scanners, are mounted on an axis which moves the recording devices 120 transversely to the work surface 210 and which, analogous to the width of the recording devices 120, carries out a displacement in the longitudinal direction after each pass, also known as pass . The

Print files 131 are not shown in the drawings.

The scan lines common in desktop scanners can be used, which are CCD lines (CCD: charged coupled device) or CIS lines (CIS: compact image sensor). For example, these lines have a resolution of 600 dpi (dpi: dots-per-inch) and can be configured to the desired lengths. To start the scan, the axis is positioned immediately in front of the edge of the object 112, either manually or automatically with assistance

a suitable sensor.

The scanner 120 moves from right to left or vice versa across the width of the object at an adjustable speed, now records the object data,

i.e. the position of each pixel is increased by the number of scan lines recorded

moves forward, makes a step of a scan line, and retracts the width from left to right or vice versa. This will be done until the scanning

ner 120 no longer records object data.

The recording of two consecutive lines can be done in the same direction, i.e. with retraction, or alternately, with the retraction being done.

is avoided and time can be saved.

Each time the scanner(s) 120 travels across the width of the object 112, they capture the position data of the object 112 that is required to create the print files 131.

An object/image file for the entire object can be created from the object data determined by the scanner 120, which causes an enormous file size for large objects. This is to be avoided and therefore the data should be sent line by line directly to the printing devices 140. In this case, each scan line can be a print file and printing can be done “on-the-fly”. This expression refers to processes in which a permanent or possibly temporary

Porous storage of data is avoided.

For this purpose, the data from the scanner 120 ideally corresponds to those of the printing unit 140 in terms of width and resolution, so every line captured by the scanner 120 can be transferred directly to the printing module 140 and the scanner 120 and the printing axis can process the object 112 synchronously with a constant line spacing .

Alternatively, a wider scanner 120 or a wider print module 140 can also be used, for example in order to process the data that is captured with one pass, i.e. pass, of the scanner(s) 120 with two or more print passes or to put together two or more scanner passes and she

to be transferred to object 112 with a print pass.

N2022/10600-AT-00

The scan data, which is recorded once, can be evaluated differently depending on the number of print sequences, i.e. the number of print passes. The number of printing sequences varies, for example, depending on whether only wood protection is to be applied or whether multi-colored decorative printing is to be carried out

should.

For the printing of a printing medium 141, for example the wood protection or all single-color decorative prints, the contour data is determined, i.e. for example geometric lengths, widths, outline data, openings, etc. This data can also be processed automatically, for example to add an allowance so that an overprint the edges are guaranteed. The pressure means 141 are in

not shown in the drawings.

The desired amount of pressure medium 141, for example the layer thickness of the wood protection and/or a base primer, can be determined via the application thickness.

can be defined by white.

The scanner 120 delivers a pixel grid, or bit map, with a resolution of, for example, 600 x 600 dpi. This data can be easily differentiated as to whether the respective pixel captured the object or a position outside the object.

The application thickness can be varied by assigning more or fewer pressure points to each scanner pixel that has captured the object, or by using variable drops, smaller or larger pressure drops. Both can

can also be combined.

Another possibility arises through a controlled application of the pressure medium 141 to compensate for the different suction or absorption behavior of the natural wooden surface. The different suction behavior creates a patchy appearance when the paint is applied evenly,

which is usually laboriously reworked in manual processing steps

N2022/10600-AT-00

must become. The typical suction behavior can be attributed to the wood color and the surface structure and therefore the application can be reduced to less absorbent sections, thereby significantly reducing the staining.

This can be done and manual rework is unnecessary.

With the multi-color printing module, a complete color palette can be created by printing the individual colors together in different application thicknesses.

the.

The application thickness, i.e. layer thickness, is determined for the object by an operator before printing begins and/or taken from an order form. Values can also be read in from a database and/or read in using a barcode or QR code. The layer thickness is specified in μm and the printer control unit program uses this to determine the resolution.

solution in dpi and the required drop size.

This means that the scan data can be converted into print data line by line. These arithmetic operations can be easily calculated “on-the-fly” in the interval scan pass to corresponding print pass, so that printing can take place after the first scan line determined and its conversion into a print file 131 and there is no need to wait until the whole thing is done Object 112 removed

is scanned or a specific part of the object.

This has the advantage that the computing time and printing time are shorter and the necessary computing operations can also be carried out with inexpensive standard hardware. Once the order thickness has been defined, the printer is able to carry out the printing process fully automatically without additional phases (i.e. printing stages) or interventions. The scan data once generated can be used for all subsequent printing phases, for example white and decorative colors. A separate printing module can be used for each printing phase

Fig. 1 shows a system according to the invention consisting of a device for printing objects 100, a work surface 210 and movement devices 220. The device 100 is used to print objects 111, 112 and 113. Of these, objects 111 that have already been printed are shown in FIG. 1 to the right of the device 100, and objects 113 that are still to be printed are shown to the left of the device.

tung. The object that is currently being processed by the device 100 is

marked with 112.

The device 100 includes a recording device 120. The recording device can, for example, include one or more cameras. The cameras can work in different wavelengths and record digitally or analogue, although the analogue signal still has to be digitized for further processing. The cameras can record the object 112 from different angles. The recording device 120 can capture the object three-dimensionally, so that differences in depth can also be captured. The recording device 120 can also include a light source, so that in the environment

training light can be dispensed with.

The recording device 120 records or records the nature of the object 112. In particular, holes 121 in the objects, recesses 122 in the objects, outlines 123 of the objects and the structure 124 of the objects

capture.

Holes 121 are naturally occurring places in the wood, such as a knothole. Recesses 122 are places created by processing the wood that are surrounded by wood, but where there is no wood itself.

that is.

Outlines 123 refer to the outer boundaries of objects 111, 112 and 113. Since these are clearly defined and marking them in the drawings is detrimental to displayability, the outlines 123 are not marked in the drawings. With structure 124 the objects 111, 112 and 113 are finally optical

N2022/10600-AT-00

Differences in the surface of objects 111, 112 and 113 are meant, such as a grain or discoloration of the wood or stone or even a structuring in artificial materials such as concrete or brick. Structure 124 can also include existing painting, printing or varnishing. Since the structure 124 is on the surface of the objects 111, 112

and 113, reference numeral 124 is not marked in the drawings.

It should be noted that the objects 111, 112 and 113 are only indicated as examples in the figures. The objects can of course have all kinds of holes, cutouts and openings. In addition, the objects with and without such recesses can be fed to the printing device 100 in any sequence. The lengths and widths of the objects are also different, as are the sizes and positions of the recesses.

The figures are for illustrative purposes only.

The device can have several such recording devices 120. These can be arranged one behind the other - i.e. in series - and, for example, record several lines - i.e. one line each by a recording device 120. Alternatively, recording devices 120 can also be arranged in parallel

net, and each record part of a line.

It is also conceivable that recording devices 120 are arranged both in parallel and in series, i.e. a line is represented by several recording devices.

gen 120 is captured, and multiple lines are captured at the same time.

If recording devices 120 are arranged in series, each recording device 120 skips after recording a line (or a part of a line, if additional recording devices 120 are arranged in parallel).

a number of rows equal to the number of serial rows minus 1.

For example, there are three rows of recording devices 120 that are connected in series

are ordered, the first row would read the following lines one after the other: 1,

N2022/10600-AT-00

4, 7, ... The second row would read the following lines one after the other: 2, 5, 8, ...

And the third row would read the following lines one after the other: 3, 6, 9, ...

However, it is possible for the serially arranged recording devices 120 to read in one line at the same time. This means, for example, that the three recording devices 120 explained above can be arranged relative to one another in this way.

It is not necessary that you read lines 1, 2 and 3 at the same time.

Each of the recording devices 120 therefore records the surface of the object 112 currently being processed line by line as a printable background. Recording as a printable background means that the areas of the object 112 that cannot be printed on, i.e. holes 121 and recesses 122 in the object 112 as well as the areas that are outside the outlines 123

of the object 112, cannot be recorded.

By recording the object 112 line by line, processing it line by line into print files 141 and printing accordingly, the processing of large amounts of data is avoided. Since this is usually the step that takes the longest in known processes, the entire process can be equalized and thus reduced.

be accelerated.

The device further comprises a processing device 130. This can be attached directly to the device 100. However, the processing device 130 can also be arranged remotely from the device 100, as shown in FIG. 1. The processing device 130 can be a corresponding computer, which is set up using appropriate software to create a print file 131 from the recorded lines of the printable background. Here-

a print file 131 is created for each line.

If recording devices 120 record a line in parallel and together, the corresponding data will be merged before the corresponding

corresponding print data 131 is created.

17737 N2022/10600-AT-00

Since the recording of one line must be completed before processing by the processing device 130, the recording device(s) 120 can record the next line of the object 112 while the processing is taking place.

device 130 creates the corresponding print file 131.

If, as explained above, several lines have been read in at the same time by serially arranged recording devices 120, the processing device 130 can also create the corresponding print files 131 at the same time. This can be done through various processes, i.e. instances, of the creation method, but also through multiple processing devices 130. It is also possible that the processing device 130 is so fast that it can create the three corresponding print files 131 one after the other, while the three serially arranged recording devices 120 simultaneously

record the next three lines.

The device further comprises at least one printing device 140, which prints the object 112 in such a way that it applies printing medium 141 to the object 112 based on the created print files 131. Here, one printing device 140 prints based on a print file 131, which is taken from the recording

Line of object 112 was created.

The movable mount may be a combination of the movement devices 220 and an attachment. There is also a drying rack on the first movable holder.

voltage device 150 attached.

Further printing devices 143 are attached to a second movable holder and also optional drying devices 150. Here is

to see that a printing device 140, 143 consists of one or more

N2022/10600-AT-00

Printheads can exist. As shown, the individual printheads can be attached to opposite sides of the axle or bracket. Alternatively, if no drying is required, the drying time is sufficient or if mixing is desired, it is possible to attach the individual elements of the printing devices on the same side. For the optional ones

This also applies to drying devices 150.

As already described above, attaching the device in a movable version is only one possibility of implementing the invention. Alternatively, the objects 111, 112 and 113 can also be transported on a movable surface, such as a conveyor belt, under static elements of the device. The movement facilities will be further

The subsequent course is described in more detail.

Pressure medium storage can be arranged on the device 100. Pressure fluid accumulators are not shown in the drawings. There is a pressure medium 141 in each pressure medium store. It is possible for each of the printing devices 140 to have access to each of these pressure medium stores and is thus able to apply each pressure medium 141. Alternatively, each printing device 140 can be assigned a pressure medium storage. This has the advantage that pressure media 141 cannot be mixed. Alternatively, printing device cleaning can be provided, for example using air, water or a cleaning liquid, which can free the printing devices 140 of pressure medium residues. Alternatively, evaporation or combustion can also be carried out. Combined pressure medium stores are also conceivable, such that one pressure medium store contains different pressure mediums 141. These can be

for example, be separated from each other by a partition.

The pressure medium reservoirs can be arranged directly on the printing devices 140, but the pressure medium 141 can also be guided to the printing devices 140 via lines or hoses. In this case, the pressure

or similar.

As a rule, all recording devices 120 should be arranged in front of all printing devices 140. However, one or more recording devices 120 can also be arranged after the printing devices 140 in order to ensure control.

Zone 1 includes the areas of objects 111, 112 and 113 that are still unprinted. Zone 2 includes the areas of the objects 111, 112 and 113 that have already been detected or are currently being detected by the recording device 120. Zone 3 includes the areas of the objects 111, 112 and 113 that have already been printed by the printing device 140 or are currently being printed. The optional drying device 150 may have dried these areas accordingly. Zone 4 includes the areas of the objects 111, 112 and 113 that have been printed or are currently being printed by the first part of a further printing device 143. The optional drying device 150 may have dried these areas accordingly. Zone 5 includes the areas of the objects 111, 112 and 113 that have been printed or are currently being printed by the second part of a further printing device 143. The optional drying devices 150 may have dried these areas accordingly. Zone 5

thus includes the finished areas of objects 111, 112 and 113.

Fig. 3 shows the dimensions of the device. Ys is the width of the area that can be recorded by the recording device 120 in one pass. Yopi is the distance between recording device 120 and printing devices 140, 143. Yo is the width of the area through each of the printing devices.

Directions 140, 143 can be printed in one pass.

It has proven to be advantageous that the distances are equal, i.e. Ys = Yoi = Yo.

In one embodiment, the device may further comprise one or more drying devices 150. A drying device 150 can use UV light, air and/or heat to dry a printing medium 141 previously applied by a printing device 140. This is advantageous if another pressure medium 141 is to be applied to the pressure medium 141. This may be the case if one of the pressure agents 141, usually the first applied one, is a primer or a protective agent. Even if printing is carried out in several color channels, several printing media are applied one after the other

A drying device 150 can therefore be attached after one, i.e. after each printing device 140 for drying. Alternatively, if the printed image is not affected, only a single drying device 150 can be attached after the last printing device 140 in order to dry the applied printing medium 141 before the object 112 is removed from the work surface or the conveyor.

If there is no need for drying, one or more can be used

Printing on the object 112 is made possible. This can be achieved by the recording device 120 and the printing devices 140 being spaced apart in such a way that the processing device 130 can create the print files 131 from the printable substrate, i.e. based on knowledge of the processing speed of the recorded substrate by the processing device 130, the expected one Time for this can be estimated with a certain degree of certainty. Since the movement of the device 100 is intended to be continuous, and the speed of which is known, can be adjusted or measured, the distance between the recording device 120 and the printing devices 140 can be selected so that the processing is completed in any case, and thus neither Delaying the movement further

complete standstill can be achieved.

The same applies to the distance between the printing devices 140 and any drying devices 150 that may be present, which are therefore spaced so that the applied printing medium 141 is dry enough to be able to apply further printing medium 141 by a next printing device 143. Here too, the time until the paint has dried to a sufficient degree is known or can be calculated or measured. With this information, the distance between the printing devices 140 and the drying devices 150 can be determined to be sufficiently large so that further printing means 141 can be added.

can be brought.

Since the distance at constant speed increases linearly with the passing time

behaves, the above also applies analogously to procedure 300.

In a further embodiment, the device is dimensioned such that the objects 111, 112, 113 can have a size of 16m x 4m. Thus can

For example, glued wood panels of this size can be processed.

In a further embodiment, the receiving device 120 can have holes 121,

Recesses 122 and outlines 123 of the object 112, as well as the structure 124

of the object 112. With the information obtained in this way, the application of pressure medium 141 at the points where no pressure medium 141 is to be applied, e.g. holes 121, recesses 122, outside the outline 123 of the object 112, can be dispensed with. In addition, the detected structure 124 can be evaluated to the effect that there is more or less pressure medium in darker, lighter, weaker or more strongly structured areas

is applied to achieve a more uniform appearance at the end.

In a further embodiment, the processing device 130 can create print files 131 from the printable substrate in such a way that the printing medium 141 to be applied results in a desired printed image. The print files can therefore receive information in particular, so that an image is created from the applied printing means 141. This can be in relief, or with different colored printing media from one or more printing devices 140, 143, this can also be a real image. This image can be of a photographic nature, but also simply depict a structure, so that, for example, an object 112 has a wood or stone look. In this case, a non-uniform surface is printed so inconsistently that in the end a uniform printed image, i.e

uniform appearance is created.

In a further embodiment, the printing devices 140 each print one line, each of these lines corresponding to a line of the object 112 recorded line by line by the recording device 120. In this case, since the processing time of one line is shorter than the processing time of multiple lines, the distance between the elements of the device can also be smaller. In addition, the processing time of one line can also be better estimated than the processing time of multiple lines, and so the security tolerance that must be maintained can be used to avoid irregularities in processing

In a further embodiment, at least one of the applied printing agents 141 is UV-curing and, if necessary, if drying devices 150 are present, at least one of the drying devices 150 is a UV lamp. By using UV curing, drying between the printing media 141 or at the end of printing can be significantly accelerated. Through this

printing can be accelerated overall.

In a further embodiment, a system 200 for printing objects 111, 112, 113 includes a previously presented device 100 for printing objects 111, 112, 113, and also a work surface 210 on which the objects 111, 112, 113 are stored can. The system 200 further comprises at least one movement device 220, which causes movement between device 100 and objects 111, 112, 113.

This is achieved, for example, by continuously moving the objects 111, 112, 113 under the receiving device 120, the printing devices 140, and possibly the drying devices 150, for example by

Alternatively, this can be achieved by continuously moving the recording device 120, the printing devices 140 and possibly the drying devices 150 over the objects 111, 112, 113. This can be achieved by mounting the devices on a movable support 220 which moves in one direction over the objects 111, 112, 113, for example on wheels, rails, ropes or rollers, or the like. Here has

Work surface 210 can be moved.

A further embodiment relates to the method 300 for printing on objects 111, 112, 113. Fig. 4 shows the process of the method 300. Here, in step 310, the surface of an object 112 is first recorded line by line as a printable background. By processing the printable background line by line, print files 131 are then created in step 320. Finally, in step 330, the objects are printed 330 on the basis of the created print files 131 by applying printing means 141.

The previously presented features of the embodiments of the device 100 can also be used analogously in the system 200 or in the method 300. This means in particular that holes and recesses can optionally be recorded as part of step 310 in step 311 and in step 331

further printing operations can be carried out.
