Description of the invention: [Technical field to which the invention pertains] The present invention relates to a laser device for applying a bar code to an object such as a personal document, for example, 'in accordance with the i-term of the patent application scope' The launcher emits at least two laser beams and each code consists of a plurality of inscriptions of lines. Meanwhile, the present invention also discloses a method for applying a bar code to an object such as a personal document, in accordance with the scope of the patent application 帛9. [Prior Art] The laser is conventionally used for the inscription of various materials, such as a material for a private member, for example, by melting the surface of the document substrate. Write-type data and image data and other such data can be applied to private documents by means of lasers. The change in time in # can be influenced by changing the laser parameters associated with the application of the material. It would be a matter of a large number of private documents that they wish to etch in time or generally remain extremely short in order to add information to individual documents. The parallel lasers, which are parallel to the target, are processed in parallel for the application of the material. However, in general, the station that carries the large-scale continuous movement on the station 'per-station personalization system' means that it is personalized for the whole process. Until the possible number, it has used the capital of multiple private documents configured to be personalized with each other 'in this case, the possible private documents need to be directed to be parallel to at least one laser. This requires extremely high construction costs and a very high production cost of 200947308. In particular, when a bar code is applied by a laser-emitting laser beam, the production apparatus as a whole requires a high throughput. Each bar code contains a plurality of bar code stripes of different widths. Depending on the width of the individual bar code strips, it is necessary to move the laser beam back and forth or to move back and forth using different frequencies to apply individual bar code strips to obtain a predetermined width stripe stripe using the resulting complex laser inscribed lines. Thus, a complete bar code includes a plurality of laser inscribed lines or a complex vector configured to be directly adjacent to each other without gaps to obtain a bar code stripe of a particular width formed by a plurality of laser inscribed lines, or obtained The width is exactly equal to the bar code of a laser inscribed line. The application of such bar codes is extremely time consuming because each must be produced by a laser beam. This means that only one bar code can be applied per unit time, so only a limited number of items such as personal documents can be passed through the device.

The simultaneous application of at least two portions of the plurality of laser inscribed lines is beneficial in effect that at least two laser beams from a common laser or a plurality of lasers can be applied with bar codes of their respective forms at the same time. Therefore, the actual processing time of the laser device can theoretically be halved. Advantageously, the aforementioned first laser beam is assigned to a first laser and the second laser beam is assigned to the first laser. One of the second lasers. This creates a situation whereby the first laser is assigned to a first object having a first bar code and at the same time the second laser can be assigned to have a first bar code a second item. For example, assuming that the item is placed on a continuously moving conveyor belt, and then briefly relayed at the first laser, the conveyor belt gives the first object barcode by the first laser beam a first portion, while the second laser beam is applied to the second portion of the other object - the second object, wherein the other object or the second object has received the laser of the bar code in the previous step Inscribed in the first part of the line. Alternatively, the first and second lasers described above or (in the case of a shared laser) the first and second laser beams of a shared laser may be collectively assigned to a single object. The object is simultaneously applied with the first and second portions of its barcode. The inch is in accordance with the preferred embodiment - the first and second portions are the same size or 'the first and second portions may be about the same Size, but There is a selectable difference in the number of inscribed lines, where the difference should be as small as possible to the minimum of 200947308. 'The first part of the complex laser engraved line contains odd numbers when the laser inscribed lines are inscribed. a laser inscribed line and the second portion of the complex laser inscribed line contains an even number of laser inscribed lines. Therefore, each second laser inscribed line is applied by a second laser beam, and each is located therebetween The laser inscription line is applied by the first laser beam. Or 'the other way of dividing the laser engraved line into two parts, spatially, the first part of the complex laser engraved line The second half of the laser engraved line of at least substantially the bar code may be included. The second portion spatially comprises a second half of the laser engraved line of the bar code, thereby forming a bar code into one The division of the first and second halves' each half is inscribed by a related laser beam. In this case, 'no matter how wide the barcode is or how many laser inscription lines are needed to complete the application of the barcode, the spatial division of the barcode into the first and second portions preferably occurs between the two code stripes so that The bar code width direction & the bar code on the left side of the divider line is completely applied by the first laser beam, and the bar code on the right side of the divider line is completely applied by the second laser beam. In a method for applying a bar code to an object using at least two laser beams of a laser device, particularly in the case of application to a private document, wherein each bar code is composed of a plurality of laser inscribed lines, at the same time, the plural The first portion of one of the laser inscribed lines is applied by the first laser beam, and the second portion of the complex laser inscribed line is applied by the second laser beam. In this method, 'when counting laser inscribed lines, the first laser beam will apply an odd sequence of laser inscription lines and at the same time the second laser beam 7 200947308 will apply an even sequence of laser inscription lines β or 'The first laser beam can be applied at least about the first half of the space' and the second laser beam can be applied at least about the second half of the space. A first portion of a plurality of laser inscribed lines of a first bar code may be applied by a first laser beam of a first laser of the laser device, configured in a first position 'at the same time as a plurality of laser inscribed lines of a second bar code The second portion can be applied by a second laser beam of a second laser of the laser device, which is disposed in a second position. Further advantageous embodiments will appear in the scope of the patent application. [Embodiment] A laser device according to the present invention is shown in Fig. 1. It can be seen that the laser device comprises a first laser 1 and a second laser 2 which are placed one after the other in the transport direction 7 of the carousel 5. The first laser 1 emits a first laser beam 3 and the second laser 2 emits a first laser beam 4. An individual private document 6 is placed over the conveyor belt 5, the surface of which will be inscribed by the laser beams 3, 4. A personal document 6a is inscribed by the laser beam 3 to produce the first portion of the bar coded laser engraved line, while a second private document 0b is being applied by the laser beam 4 to the second portion of the bar coded inscription line. - The entire bar code can contain, for example, 260 outputs from two lasers 1 and 2

When using a total of two lasers 2, 2 according to the invention, the number of vectors or laser inscribed lines to be applied can be equally divided between the laser beams 3, 4 such that the first part of the laser engraved line The second portion of the laser inscribed line is applied by the first laser beam 3 and is applied by the second laser beam 4. This division results, for example, that 13 vectors are applied to the document by the first laser beam 3 "become its first part, while the second group " ο vector is applied to the document 6be by the laser beam 4 When the document 6a is moved by the stepwise and/or continuous movement of the conveyor belt 5 in the direction of the arrow 7 to reach the second laser beam 4, the second part or the second 13-strip vector or thunder The inscription line is also applied to the document 6a, which causes each document to have a fully applied bar code after passing the two lasers. In order to demonstrate such a laser inscribed line applied to two or more lasers The utility of the division 'The following table is based on two examples - the device is divided by bar code in this type, ') relative to the traditional application method (" unused bar code division ") in the relative effect of production volume and total processing time, The total processing time in # contains additional processing time independent of the laser processing time. 9 200947308 Table is not divided by barcode

When an object or a document passes completely through the two laser beams 1 and 2, it obtains the combined code indicated by reference numeral 1 which is equal to the original predetermined bar code represented by reference numeral 8, again by Ray. The combination of the inscribed lines i2a and 12b "This results in a significant reduction in laser processing time, which can work with both the first and second laser beams. Another different way of dividing the laser engraved lines of the bar code is shown in Figure 4. As shown in this bar code plan view, spatially, the bar code, the left portion or the first half 14 is applied by the first laser beam of the first laser, and the right portion or the second of the bar code 13 The half section 15 is applied by a second laser beam of the second laser. A separation line 13a is drawn in the manner of being separated such that it separates two portions 14, 15 having an equal number of laser inscribed lines, wherein the bar code stripes are represented by reference numerals 16, 17, 18, and 19 A different number of laser inscription lines may be included, extending from the top end to the bottom end and parallel to each other. In theory, the dividing line 13a is arranged in such a way that it lies between the two code strips and takes into account that the first portion 14 of the laser inscribed line contains a slightly less or a little more than a laser inscribed line. By virtue of the above-described divisions shown in Figures 3 and 4, this situation is effectively achieved, compared to the total number of laser inscribed lines, the laser beam of the laser only needs to apply half of the laser inscription line here. , resulting in shorter laser processing times and overall higher device throughput. All the features disclosed in the specification, which are novel or novel to the prior art, alone or in combination, are the basic claims of the present invention.
