    The invention describes a parking and / or marking of a workpiece with a laser plotter or laser engraver, in which a plurality of, in particular two, beam sources in the form of lasers are used in one housing of the laser plotter acting workpiece, wherein the workpiece is deposited defined on a working table and a laser beam emitted from the beam source is transmitted via deflection to at least one trained for both beam sources focusing unit, from which the laser beam is deflected towards the workpiece and focused for processing, wherein the control , in particular the position control of the workpiece to the laser beam, via a software running in a control unit, wherein on an external component, in particular a computer or a control device, a graphic and / or text is created, which to the control unit of the Las is transferred from a stored database conversion of the transferred data, in particular the graph and / or the text, for controlling the individual elements of the laser plotter (1), as described in claims 1.
    The invention further relates to a laser plotter for engraving, marking and / or inscribing workpieces, comprising a machining table for positioning the workpiece, at least two radiation sources in the form of lasers with corresponding deflecting elements and a preferably movable focusing unit and a control unit for controlling the individual elements. wherein the control unit is designed to receive data generated on an external component, in particular a graphic and / or a text, and a database for converting the transmitted data is arranged, as described in claim 10.
    From the prior art, in particular WO 1999/038643 A, a laser plotter is known for engraving, marking and / or inscribing, in which a plurality of, in particular two, radiation sources in the form of lasers are arranged and operated in one housing. The lasers preferably act alternately on the workpiece to be machined, wherein the workpiece is positioned defined on a machining table. In this case, a laser beam emitted by the radiation source is transmitted via deflecting elements to at least one focusing device formed for both radiation sources, from which the laser beam is deflected in the direction of the workpiece and focused for processing. The control, in particular the position control of the workpiece to the laser beam via a running in a control unit 2 software. In this case, on the other hand, the following is added: KpJUPQflpniq ,. In particular, a computer or a control device creates a graphic and / or text which is passed to the control unit of the laser plotter, which converts the stored data from a stored database, in particular the graphics and / or the text, for controlling the individual Elements of the laser plotter take off.
    The disadvantage here is that in such a laser plotter, the assignment of the individual radiation sources, in particular laser, must be set manually to the textures of the materials of the workpiece by the user with each new operation.
    US Pat. No. 4,877,939 A discloses a device for processing workpieces by means of laser radiation, which device has a first laser with a first wavelength and a second laser with a second wavelength. In this case, the first laser assumes a Vorabrbearbeitung the surface, in particular a pre-scoring of the workpiece, whereupon the second laser delivers the actual working beam. The lasers can be of different types, such as C02, YAG or UV lasers.
    Furthermore, US Pat. No. 6,313,433 B and US Pat. No. 6,423,925 B describe a laser processing apparatus which comprises a beam deflection apparatus with which a processing beam can be adjusted in the XY plane and has two independent, independently controllable laser sources. The two laser sources are operated parallel to each other.
    The present invention is based on the object to provide a laser plotter and a method for engraving, marking and / or labeling, are used without interruption in a workflow different laser sources for different surfaces, so that the quality is improved and achieves a high working time savings becomes. Another object is to improve the ease of use of such a laser plotter and to minimize possible input errors.
    The object of the invention is achieved in that the assignment of the different radiation sources to the transferred graphics and / or text in the form of colors, in particular a color code is carried out, wherein in the database to the different 3
    Colors a correction value for cfie.ünt # schi ^ i & eT fVsföemen, in particular a height correction value for compensation of the different focal positions or focal lengths of the different radiation sources is deposited.
    It is advantageous here that the user thus inputs the data, in particular the correction value for the different lasers, and then this data can be used for each renewed engraving process. Since the assignment of the laser is defined by colors, the likelihood of confusion is significantly reduced, since the colors can be adapted to the materials to be processed. A significant advantage is that it is now simply possible that for different levels and different depths of engraving simply different colors are defined, so that a very simple assignment is possible and not, as is customary in the prior art, corresponding values for the different conditions must be entered. Another significant advantage is that the use of colors as a criterion for differentiating the different laser and / or engraving depths and / or processing levels has now created the possibility that a multiplicity of different programs or software can be used, for this purpose only on the program the appropriate color or color code must be selected. This allows each user to use his favorite software and no adjustments, conversions and / or programming operations when exchanging data with the control unit of the laser plotter must be made. By storing the values once, input errors are avoided.
    But it is also the measures in which on the external components standardized programs, such as Word, Excel, Paint, Corel Draw, etc. baptized, of which the graphics and / or text created with different colors and then to the control unit of the Laserplotters are advantageous because it can be used a familiar to the user software, whereby the high cost of training and adjustments that are necessary for special control programs, can be saved. This also ensures that the user can choose the best possible interface for him to create the graphic or the text.
    By the measures in which different colors are defined on the external component for different engraving depths and / or different workpiece heights, and these colors are differentiated, it is advantageously achieved that not only planar workpieces or blanks are processed But also an optical representation of the engraving or the text is easily possible, whereby the user immediately recognize the different heights due to the different colors or can assign.
    Also advantageous are the measures in which in the external components or in the transmission to the control unit or by the control unit itself each color of the graphic and / or the text is assigned a certain predefined color code, as this in a simple way to adapt the laser plotter can be done.
    But also advantageous are the measures in which by the control unit of the laser plotter, the color, in particular the color codes, from the different extemren components, in particular the different graphics software programs, is adopted, since thus a faster transmission time is achieved because no adjustments more must be made and still a clear assignment is possible.
    In a measure in which in the control unit of the laser plotter the color codes transmitted by the different components are each assigned to a color code stored for the external component used, it is advantageously achieved that a corresponding adaptation can be made for each application , This allows an even higher quality can be achieved or the user can be provided depending on the application more colors available.
    But there are also measures of advantage, in which a color, in particular a color code by a range, in particular a range from / to, is determined, since thus a greater allocation possibility is created and the user no longer the exact predetermined color, in particular with the exact color code, must use. Thus, the color choice for the user on the different programs is much easier. 5
    It is also advantageous to combine the dimensioning factor of the radiation source with the color code for the engraving depth, as this does not require the user to pay any attention to the different laser or radiation sources to be used.
    An advantage is also a measure in which a ballpoint pen with different engraving areas and different height positions is used as the workpiece, since different colors can be defined for the different areas and levels, so that the creation of a graphic and / or text is simplified. because the user does not have to take care of any circumstances of the workpiece, such as different engraving planes.
    Furthermore, the object of the invention for a laser plotter is solved such that the different sources of radiation to the transferred graphics and / or the transferred text in the form of colors, in particular a color code, can be assigned, wherein in the database to the different colors a correction value for the different positions, in particular a height correction value, the different radiation sources is deposited.
    The advantage here is that a very simple operation for the user is created, the engraving properties of the graphic created or the text are also visually recognizable to the user software. It is also possible to use a very large number of standardized programs or software.
    An advantage is an embodiment in which for the engraving of the workpiece, the processing table and / or the focusing unit are adjustable in height, as this processed in a simple manner different levels and / or different engraving depths can be generated.
    In one embodiment, in which the external components by a computer or a control device on which a software for creating the graphics and / or the text is applicable, is formed and connected via a secure fast data connection to the laser plotter, in particular the control unit is, is achieved in an advantageous manner that this gives the user the possibility that this can use any software for creating the graphic and / or the text. This also creates the possibility for the user to use the graphic and / or the text in one of the 6
    Laserplotter separated space in RuÄejersterienkann.uQCl.diese * then transferred for processing over a standard network, in particular via an intranet, to the laser plotter.
    In the embodiment in which different colors are defined for the different radiation sources and for the different engraving depths, it is advantageously achieved that the user can create on any software the graphics and / or the text which has the corresponding color to choose from , This also eliminates the need for the user to enter values for the corrections and heights more so that typing errors can be eliminated.
    Another advantage is an embodiment in which the workpiece is formed as a ballpoint pen with several engraving areas and different engraving heights, as this different colors can be set for the different areas and thus the operation is very simplified.
    Also advantageous is an embodiment in which a color code is assigned in the database to the different colors, as this may be necessary corrections in a simple manner by adjusting the color code can be made.
    Finally, an embodiment is advantageous in which in the database for a color, in particular the color code, an area, in particular a range from / to, is deposited, since thereby the selection of the color in the various programs is simplified because of Users no longer have to choose the exact color, but can choose colors that fall into this area.
    The invention will now be described in the form of an embodiment, it being understood that the invention is not limited to the illustrated and described embodiment.
    It shows:
    Fig. 1 is a schematic representation of a laser plotter;
    Figure 2 is a schematic representation of a workpiece in the form of a ballpoint pen. 3 shows a side view of the workpiece, in a simplified schematic representation. 7
    Importantly, it should be noted that in the various embodiments, the same parts are provided with the same reference numerals or the same component names, the disclosures contained throughout the description can be mutatis mutandis to the same parts with the same reference numerals or the same component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the described figure and are mutatis mutandis transferred to the new situation in a change in position. Also, individual features or combinations of features from the illustrated and described embodiments may represent separate inventive solutions.
    In Fig. 1, a laser plotter 1, or also called laser engraver, shown schematically, in which in a housing 2 more, in particular two radiation sources 3 in the form of lasers 3 a, 3b are arranged and operated, preferably alternately on the workpiece to be machined 4, wherein the workpiece 4 is positioned defined on a processing table 5, and a laser beam 6 emitted by the radiation source 3 is transmitted via deflection elements 7 to at least one movable focusing unit 8 designed for both radiation sources 3, from which the laser beam 6 in the direction of the workpiece 4 distracted and focused for editing. The control, in particular the position control of the workpiece 4 to the laser beam 6 via a software running in a control unit 9, wherein on an external component 10, in particular a computer or a control device, a graph and / or text, as shown schematically on the computer created is, which / r is passed to the control unit 9 of the laser plotter 1 via a data link 12, which converts from a stored database, a conversion of the transferred data, in particular the graph and / or the text 11, for controlling the individual elements of the laser plotter 1. The detailed mechanical structure of such a laser plotter 1 will not be discussed in any more detail since it is already known from the prior art, in particular from WO 1999/038643 A of the Applicant, and can be taken from this.
    According to the invention, it is now provided that a simplification of the control of the laser plotter 1 is created, so that the operation is facilitated for the user and it comes to minimizing errors for the assignment of the laser 3a, 3b. For this, the assignment of the different radiation sources 3 to the transferred graphic and / or to the 8 transferred text 11 takes place in the form of fefts * jÄ ^ ij $$ ojüer ^ Qines.Farb - Codes, wherein in the database for the different colors a correction value for the different positions, in particular a height correction value, for the compensation of the different focal positions or focal lengths of the different radiation sources 3 is deposited or is.
    It can therefore be said that each laser 3a, 3b is assigned its own color, whereby this color in the database is assigned a value for correcting the wavelength. For example, for the processing of wood of the first radiation source 3, in particular the first laser 3a, the color "brown" be assigned, whereas the second radiation source 3, in particular the second laser 3b, the color "gray" is assigned for the processing of metal , Thus, the user can easily assign the lasers 3a, 3b to the materials to be processed, so that the risk of confusion and the incorrect entry of values is minimized, ie, for example, the color brown for the processing of wood, in particular the radiation source 3 for wood used whereas the processing of metal with the color gray, in particular the radiation source 3 for metal, is carried out and preferably the most different shades are assigned to the colors correspondingly. Since the colors in the database are assigned a corresponding correction value once, the user only needs to create the graphic or the text 11 with the correct color, whereupon the control system decides the corresponding correction. Thus, constantly recurring input errors can be minimized.
    To create a graphic or text 11, the user may use an external component 10, particularly a personal computer, laptop, etc., running a standardized program such as Word, Excel, Paint, Corel Draw, and so forth. For this purpose, the user can easily create the graphics and / or the text 11 in the programs, in which case he already selects corresponding colors from, that is, the graphics and / or the text 11 created in color. The external component 10 is then connected to the control unit 9 of the laser plotter 1, so that the graphics and / or the text 11 can be transmitted to the control unit 9. Of course, it is possible that the external component 10 is already connected to the laser plotter 1, in particular the control unit 9, when the graphics and / or the text 11 are being created. It is also possible that the laser plotter 1 has a graphic display (not shown), and that the user creates the graphic and / or the text 11 directly on the laser plotter 1. It is also possible that a standardized 9
    Program, such as 3 $ £ <$ rd, £ x <$, Draw, etc., is installed directly on the laser plotter 1, to which the laser plotter 1 with appropriate hardware for operating a necessary operating system and programs has. For this purpose, it is possible that the operating system and the programs runs in the control unit 9 or that this is a separate unit is integrated, runs on the software and passes the data to the control unit 9. The control unit controls the individual elements of the laser plotter 1 for generating an engraving, marking and / or a label on the workpiece 4.
    Since there are different color tones in such standardized programs, the colors are assigned different color codes, to which the user can specify a corresponding area in the database, ie, that the user in the database indicates a value of / to, so that each same or Intermediate value of the corresponding radiation source 3 is assigned. Of course, it is also possible that the user inputs only one value and that a defined range is automatically determined or determined by the database. It is also possible for each program to be defined independently of each other, so that special programs can be used which use a completely different color code or use a different identifier instead of a code. This defines the user previously in the database and assigns this program a corresponding from / to area, so that with the subsequent data transmission, the control unit 9, the software preferably automatically recognizes or records the data transfer / identifies and stores, so at a renewed data transfer a automatic recognition of the software is possible and the corresponding values can be assigned. For this purpose, it is advantageous if the user manually starts the recording of the transmission before the data transmission, since this ensures that a complete data record is transmitted, which is to be recorded by the user aware. Especially for special programs with special codes, the software, in particular the data or codes, can be recorded easily and without error.
    It is also possible for different colors to be defined on the external component 10 for different graphic depths and / or different workpiece heights 13, 14 or planes, and for these colors to be assigned different height values, ie for a workpiece 4 with a structured surface, or for different surface heights a certain color can be assigned, to which in the database 10 fl for the control unit 9 another ßpjr ^ tjjryjqö Hptg $ eg1 iKird assigned, so that the different focus points of the common focusing unit 8 of the different laser 3a 3b are compensated and the user no longer has to take them into account. It is also possible that different colors are used for the different engraving depths, to which then additionally the correction value is set or entered and stored.
    Preferably, in the external components 10 or in the transmission to the control unit 9 or by the control unit 9 itself, each color of the graphic and / or the text 11 is assigned a specific predefined color code. This ensures that there is always a value for the most different colors or shades, and thus, given a suitable design of the area in the database, reliable detection for the laser 3a, 3b to be used is available. If, for example, a color or a color code is used that has not yet been stored or stored, then it is possible that an error message is output when transferring or assigning a value from the control unit 9, so that the user, before starting the engraving, Marking and / or labeling process can assign this value to a laser 3a, 3b or enter a corresponding value. In such a case, the user also has the option of additionally storing this new value in the database for a radiation source 3, so that this value or color can in turn be assigned to a new process. Usually, the colors, in particular the color codes, are taken over by the control unit 9 of the laser plotter 1 from the different external components 10, in particular the different graphics software programs, but it is also possible that these values are adapted accordingly during the acquisition can, that is, for example, depending on the program used, a corresponding key is deposited, which modifies the transferred color codes accordingly. Thus, the storage space in the database can be kept low because of the various programs, the values are converted accordingly and thus only a small number of color codes must be stored. It also makes it easy to use new programs or codes that have not yet been defined and then only have to be assigned correctly. 11
    The laser plotter is preferably equipped such that a corresponding display is provided on which the graphics and / or the text 11 created on the external components 10 are displayed. For this purpose, the user gets the information as to which laser 3a, 3b is associated with which color or the user can run a simulation where he sees which laser 3a, 3b is used when and to which graphics or text 11. Thus, a simple control directly on the control unit 9, in particular on the laser plotter 1, possible. Of course, it is possible that the user can make corrections directly on the laser plotter.
    For example, it is possible for the workpiece 4 to be formed as a ballpoint pen 15 having a plurality of engraving areas 16, 17 and different engraving heights or workpiece heights 13, 14, that is to say the engraving areas 16, 17 are arranged in different planes. It is possible that in the programs, in particular on the external components 10, or in the control unit 9 itself the ballpoint pen 15 or other workpieces 4 is stored or deposited as a template, so that the user can easily call this again and again. By storing the workpiece 4 as a template, the user also has the advantage that he can define or store corresponding engraving areas 16, 17 or labeling areas to which specific data, information, etc. are stored. When using a ballpoint pen 15 as a workpiece 4 two engraving areas 16, 17 are preferably present, as shown schematically in dashed lines in Fig. 2, wherein the first engraving area 16 is at the base body 18 of the ballpoint pen 15 and the second engraving area 17 on the Mounting bracket 19 is arranged. As a result, the two engraving regions 16, 17 have different surface planes, which must be taken into account during processing. Furthermore, it is often the case that in ball writing 15 and different materials, such as wood as a base body 18 and metal as a mounting bracket 19 or plastic as a base 18 and metal as a mounting bracket 19, are used, which in turn is important for processing, since the available lasers 3a, 3b are used for the processing of different materials. Thus, it is necessary for a high-quality engraving, marking or inscription that the correct laser 3a, 3b is used for the material to be engraved, so that with different materials the processing of the ballpoint pen 15 is performed with both lasers 3a, 3b in one operation, ie, the ballpoint pen 15 is once positioned on the machining table 5, and then after the machining operation first the first engraving area 16 is machined with eg the second laser second engraving area 17 with, for example, the first laser 3a without the workpiece 4 or to take the ballpoint pen 15 from the processing table 5 or to change the position or to use or replace another radiation source 3 after the first processing. For example, the first laser 3 a is formed by a CO2 laser with a power of up to 200 watts for processing of metal and the second laser 3b by an infrared diode laser with a power up to 100 watts for processing wood or plastic. Of course, it is possible that using similar lasers 3a, 3b with similar power, the processing of an engraving area 16, 17 could be performed alternately with both lasers 3a, 3b. For the sake of order, it is also pointed out that, of course, any number of engraving areas 16, 17 can be arranged, created or defined on a workpiece 4, in particular on the ballpoint pen 15.
    Such a procedure for the engraving of a ballpoint pen 15 can be carried out, for example, as follows:
    The user selects in the standardized programs on the external component 10 from deposited workpieces 4 a specific workpiece 4, such as the pen 15, from. This workpiece 4, in particular the selected ballpoint pen 15, is then displayed graphically on the display or on the screen of the external component 10, with the possible engraving regions 16, 17 being shown schematically at the same time. The user can now call this by clicking on an engraving area 16,17, whereupon he is asked to determine the material for this engraving area 16,17, for which purpose, for example, a stored listing is displayed, from which he the material to be processed, such as wood, Plastic, metal, etc. selects, ie in that, after the actuation or activation of an engraving area 16, 17, a selection of the material to be processed and / or of the laser 3a, 3b to be used takes place. After selecting the appropriate material for this engraving area 16, 17, the user now gets the possible color codes and / or colors in the form of points, bars, etc. displayed on the display, so that the user after selecting the color of a corresponding graph 11 and a corresponding text 11 with this color in the selected engraving area 16, 17 can create, ie, that the user for an engraving area 16,17 defined colors and / or color codes selects. It is of course possible that different engraving heights or engraving depths are also used within an engraving area 16, 17. ································································································································································································································································································ of parameters such as engraving depth, engraving width, etc., stands or is assigned to it. Preferably, the displayed colors are displayed appropriately labeled, so that the user can immediately recognize which color is used for what. For example, the engraving depth or engraving width can be entered within the color bar or a color point so that the user can recognize or read the color and the engraving depth or engraving width at a glance. After the user has created the graphic 11 and / or text 11 for the first selected graphics area 16, he simply selects the next engraving area 17, which in turn prompts him to select the material for that area. If he now selects another material, it is preferred to provide him with a different color palette for the first engraving area 16 with other material. Thus, an unambiguous assignment of the colors is always given and the user can thus not confuse them or a color occurs only once for a particular engraving process with differently stored parameters.
    It is essential in such a simplified process that in the database and / or the stored workpiece 4, the data are stored accordingly. For example, in the process described above for a color one or more of the following data or parameters are stored: radiation source 1 or 2, engraving depth, workpiece plane, correction value for the laser, engraving width, engraving depth, power of the beam source, -Frequency, - speed, - passages, - gas, - material, - high quality, - color and / or color code (especially range color code from ... to ...), - workpiece level, engraving area, - workpiece (especially workpiece name , Workpiece number) etc.
    Thus, in a simple manner over the prior art, a significant simplification for the user is created, whereby the error sources can be minimized. The user does not need to pay any attention to the correction or focusing for the different lasers, since these are already stored. In such a sequence is also achieved in an advantageous manner that the wrong inputs are minimized, since the user can only select from the engraving areas 16,17 assigned assignments. It is essential here that after the selection of an engraving area 16, 17 the user now has to select a material or laser 3a, 3b to be machined, whereupon only those colors are given to the user for grouting the material 3a or laser 3a or 3b are possible, ie that when selecting a material, the corresponding laser 3a, 3b is deposited with the corresponding correction value and the user now a proposal for the most different engraving depths and / or engraving widths, etc. is provided with a wide variety of colors available. For the formation of the different engraving depths, the machining table 5 is moved in accordance with the stored values in the illustrated embodiment.
    Furthermore, it is possible that in the delivery of the laser plotter 1 in a memory of the laser plotter 1 or in a memory of an external control unit 9 for the laser plotter 1 or on a supplied CD-ROM or DVD standardized workpieces 4, such as different ballpoint pens 15, Bottle openers, knives, etc., for a variety of application software included. In these predefined workpieces 4, the most common engraving areas 16, 17 are defined on the virtual workpieces 4, for which purpose a separate color palette is preferably stored for each possible engraving area 16, 17. The user thus only needs to adjust the workpieces 4, in particular the engraving area 16, 17, to his blanks to be machined and to input the corresponding correction values for the lasers 3 a, 3 b used or to select his lasers 3 a, 3 b from a list. The other required data, such as the engraving depth, the processing height or processing area, etc., are already stored to the stored workpieces 4 and to the different possible colors, whereby a simple start-up of such a laser plotter 1 is possible.
    It is of course possible that the user can edit the stored workpieces 4 and set new engraving area 16,17 or already predefined engraving areas 16,17 can be deleted or extended. It is also possible to simply modify the stored data or values and thus adapt them to its required values.
    Furthermore, it is also possible that a recognition device 20 is arranged in the laser plotter 1, which automatically detects the radiation sources 3 used. In the case of an exchange of one or both of the radiation sources 3 via the recognition device 20, it is possible for the newly used radiation sources 3 to be recognized and to be displayed to the user or for the correction values to be automatically adapted, ie for a variety of correction sources 3 to be stored in a database If, for example, the currency exchange rate for the old one is changed, then at the time of exchange of the most current amount of money Radiation source 3 stored value is changed. In this case, however, it is also possible that the radiation source 3 has a chip, bar code, memory or transponder, in particular an RFID element, which is interrogated by the recognition device 20. In these systems, it is possible that the most diverse data of the radiation source 3 are supplied, which can be queried via the recognition device 20 and automatically adjusted. In particular, it is advantageous if the correction value is stored, as this eliminates the need for an internal database for a wide variety of radiation sources 3 and allows newly developed radiation sources 3 to be used without the user having to manually enter the correction value or having to wait for a database
    It is also possible that in the absence of automatic recognition device 20, the user has such a radiation source database available, from which he can manually select a radiation source 3, so that all necessary data, in particular the correction value can be adjusted accordingly.
    The automatic detection of the radiation sources is particularly suitable if the laser plotter I is designed for modular use for a variety of lasers 3 a or 3 b, that is, for example, for a wide variety of workpieces 4 different radiation sources 3 are used, which replaced with little effort can be, including a Aufhahmevorrichtung (not shown) is used with automatic positioning and contacting. Thus, if a user exchanges a radiation source 3, the new radiation source 3 used is detected and the corresponding data is retrieved, which are then used.
    Of course, it is also possible that with the laser plotter 1 described above, the workpiece 4 to be machined can also be cut, that is, the focal point of one of the two lasers 3a, 3b is placed below the workpiece 4 or the processing table 5 is moved and the machining process several times is performed in succession, so that the laser beam 6 penetrates through the workpiece 4 and cuts it at this point. It is also possible that during processing of the workpiece 4 only a color change of the surface is created.
