Description
Leseanordning for tekst på bevegelig stykkgodsReading device for text on moving parts
Oppfinnelsen vedrører en leseanordning for påtrykk spesielt på forflyttet stykkgods, som på et transportorgan forflyttes gjennom opptaksfeltet for et kamera, hvor et påtrykk, som befinner seg i kameraets synsfelt og er dannet av punkter, oppfanges og omformes til signaler til styring av etterfølgende operasjoner. The invention relates to a reading device for impressions particularly on moved piece goods, which are moved on a transport device through the recording field of a camera, where an impression, which is in the camera's field of view and is formed by points, is captured and transformed into signals for controlling subsequent operations.
Fra DE-OS 30 10 112 er det allerede kjent en anordning for automatisk sortering av stykkgods, hvor det finnes et kodemerke med rotasjonssymmetrisk struktur som kjennetegn, som inneholder omkodede bokstaver og tallrekker, som gjennom en fotoelektrisk anordning omformes til elektriske signaler og således tjener til styring av de etterfølgende operasjoner. Denne styring forutsetter ikke bare en omkoding, men krever også en bestemt struktur, som bare kan framstilles på spesi-elle trykkerimaskiner. Trykkingen og påføringen av kode- From DE-OS 30 10 112, a device for automatic sorting of piece goods is already known, where there is a code mark with a rotationally symmetrical structure as a characteristic, which contains recoded letters and numbers, which are transformed into electrical signals through a photoelectric device and thus serve to management of the subsequent operations. This control not only requires a recoding, but also requires a specific structure, which can only be produced on special printing machines. The printing and application of code-
merket er således kostbar og tungvint, idet selve kodemerket ikke umiddelbart kan avleses. the mark is thus expensive and cumbersome, as the code mark itself cannot be immediately read.
Oppfinnelsens oppgave er derfor å forenkle framstillingen av påtrykket og dets avlesning. The task of the invention is therefore to simplify the production of the impression and its reading.
Denne oppgave blir ifølge oppfinnelsen løst vedAccording to the invention, this task is solved by
at opptaksfeltet overtones eller oppløses gjennom en raster, hvis rasterbredde høyst er så stor som diameteren av et punkt av tegnet i påtrykket. that the recording field is overtone or dissolved through a raster, whose raster width is at most as large as the diameter of a point of the character in the overprint.
De fordeler som oppnås med oppfinnelsen består særligThe advantages achieved with the invention consist in particular
i at det gjennom rasteren oppstrå en høy oppløsnings evne, hvorigjennom også små tegn kan leses feilfritt samt utnyttes. Tegnene kan dessuten framstilles med trykkerimaskiner som er vanlige i handelen, slik at spesialtrykkerianordninger bort-faller. Som følge av den høye oppløsning (overtoning) kan tegnene også trykkes i klarskrift, slik at påskriften også in that a high resolution capability emanates through the raster, through which even small characters can be read flawlessly and utilized. The characters can also be produced with printing machines that are common in the trade, so that special printing devices are eliminated. As a result of the high resolution (overtone), the characters can also be printed in plain text, so that the inscription as well
kan leses direkte av personer samt kontrolleres.can be read directly by people and checked.
En overføring i kodetegn kan således sløyfes. Derved forenkles likeens påskrivningen og overvåkingen. A transmission in code characters can thus be skipped. This simplifies the registration and monitoring of the corpse.
Ytterligere trekk ved oppfinnelsen går fram av underkravene. Et utførelseseksempel på oppfinnelsen er vist på tegningen og blir nærmere forklart i det følgende. Fig. 1 viser en skjematisk framstilling av leseanordningen. Further features of the invention are apparent from the subclaims. An embodiment of the invention is shown in the drawing and is explained in more detail below. Fig. 1 shows a schematic representation of the reading device.
Fig. 2 viser framstillingen av et påtrykk.Fig. 2 shows the production of an overprint.
I fig. 1 er vist et transportorgan 1, hvorpå stykk-godset 2 transporteres. Transportorganet 1 kan etter ønske være utformet som rulle-, bånd- eller kjedetransportør. Det stykkgods 2 som blir transportert på dette transportorgan 1 bærer på sin oppadvendte flate et påtrykk 3. Ovenfor transportorganet 1 "er et. kamera >4' i form av et. videokamera for industriell bruk slik anbragt at hvert stykkgods 2 må passere kameraets 4 opptaksfelt 5. Kameraets 4 opptaksfelt 5 strekker seg over hele bredden av transportorganet 1, slik at hvert stykkgods 2 i uinnrettet stilling og dessuten uavhengig av sin vinkelstilling i forhold til transportretningen kan be-vege seg igjennom opptaksområdet 5. In fig. 1 shows a transport device 1, on which the piece goods 2 are transported. The transport member 1 can, if desired, be designed as a roller, belt or chain conveyor. The piece goods 2 that are transported on this transport means 1 bear on their upward facing surface an impression 3. Above the transport means 1 "is a camera >4' in the form of a video camera for industrial use arranged so that each piece goods 2 must pass the camera's 4 recording field 5. The recording field 5 of the camera 4 extends over the entire width of the transport member 1, so that each piece of goods 2 in an unaligned position and furthermore regardless of its angular position in relation to the direction of transport can move through the recording area 5.
Inntredelsen i opptaksfeltet 5 kontrolleres gjennom en lysdetektor 6 e.l. og videreføres til en hovedstyreenhet 7, som sørger for mikroprosessorstyringen og bildeutnyttelsen, altså tjener som bildeutnyttelsessystem. Der blir det bilde som er tatt opp analysert av en modular mikroprosessor samt omformet til signaler, som ved det etterfølgende grensesnitt-sted (Schnittstelle) 8 mates ut som data. Disse data tjeffer til styring av etterfølgende operasjoner, såsom målstyring, sortering, bearbeidelser e.l. og videreføres til en data-utnyttelsesenhet. For kontroll er det til hovedstyreenheten 7 ytterligere koblet en monitor 13. Det framgår at de etter kameraet 4 koblede apparater 7,8,9 og 13 kan monteres sær-skilt, slik at monteringen av leseanordningen til enhver tid kan tilpasses de aktuelle plassforhold. Entry into the recording field 5 is controlled through a light detector 6 or the like. and is passed on to a main control unit 7, which provides the microprocessor control and image utilization, i.e. serves as an image utilization system. There, the recorded image is analyzed by a modular microprocessor and transformed into signals, which are output as data at the subsequent interface location (Schnittstelle) 8. This data leads to the management of subsequent operations, such as target management, sorting, processing etc. and is passed on to a data utilization unit. For control, a monitor 13 is additionally connected to the main control unit 7. It appears that the devices 7,8,9 and 13 connected after the camera 4 can be mounted separately, so that the mounting of the reading device can be adapted to the relevant space conditions at all times.
Fig. 2 viser påtrykket 3 i forstørret målestokk.Fig. 2 shows the impression 3 on an enlarged scale.
Det består av en rekke av tegn 10, som er satt sammen av punkter 10' og som i omkodet eller fortrinnsvis i ukodet It consists of a series of characters 10, which are composed of points 10' and which in recoded or preferably in uncoded
form, altså klarskrift, inneholder den melding som skal over-føres. For å lese tegnet 10 blir opptaksområdet 5 og således også påtrykket 3 delt opp med en raster 11, hvis rasterbredde høyst er så stort som et punkt 10' av tegnet 10. Dermed kan form, i.e. plain text, contains the message to be transmitted. In order to read the character 10, the recording area 5 and thus also the imprint 3 is divided up by a raster 11, whose raster width is at most as large as a point 10' of the character 10. Thus,
med to rasterpunkter 10' tegntykkelsen avføles på en sikker måte. Rasteren 11 oppviser i opptaksfeltets breddeutstrekning minst ca. 1000 rasterpunkter, slik at det ved en opptaksfelts-bredde på 600 mm oppstår en rasterbredde på 0,6 mm og således en tegntykkelse som skal påvises på 1,2 mm. Alt etter kameraets 4 avstand i høyderetningen fra påtrykket 3 kan rasterbredden også utgjøre 0,4 mm, d.v.s. en tegntykkelse på 0,8 mm ved en tegnhøyde på 6 mm. with two grid points 10' the character thickness is sensed in a safe way. The raster 11 exhibits in the width of the recording field at least approx. 1,000 raster points, so that with a recording field width of 600 mm, a raster width of 0.6 mm occurs and thus a character thickness to be detected of 1.2 mm. Depending on the distance of the camera 4 in the height direction from the impression 3, the grid width can also amount to 0.4 mm, i.e. a character thickness of 0.8 mm at a character height of 6 mm.
For å påvise posisjonen av påtrykket 3 innenfor opptaksfeltet 5, er det f.eks. ved randen anbragt gjenkjennelses-bjelker 12. Disse oppviser en bredde som svarer til minst tre rasterbredder, slik at de entydig skiller seg fra de andre tegn. På grunn av tilordningen av disse gjenkjenn-kjennelsesbjeiker 12. Disse oppviser en bredde som s/arer til minst tre rasterbredder, slik at de entydig skiller seg fra de andre tegn. På grunn av tilordningen av disse gjenkjennelses-bjelker 12 kan posisjonen av påtrykket 3, særlig dets vinkelstilling i forhold til transportretningen, slås fast, hvor-etter tegnene 10 kan identifiseres. Selve avsøkingen skjer ved hjelp av en egnet avsøkingsprosess. Som følge av den høye oppløsningsevne har skråstillinger på opptil ca. 20° In order to detect the position of the impression 3 within the recording field 5, it is e.g. recognition beams 12 placed at the edge. These have a width that corresponds to at least three grid widths, so that they clearly differ from the other characters. Due to the assignment of these recognition beams 12. These have a width equal to at least three raster widths, so that they clearly differ from the other characters. Due to the assignment of these recognition beams 12, the position of the print 3, in particular its angular position in relation to the transport direction, can be determined, after which the signs 10 can be identified. The screening itself takes place using a suitable screening process. As a result of the high resolution, inclined positions of up to approx. 20°
i forhold til horisontalen ingen innflytelse på resultatet av utnyttelsen. Påtrykket 3 kan også være anbragt under en klar, gjennomsiktig folie, eksempelvis en krympepakning. Da stykkgodsets transporthastighet tas hensyn til undervurderingen, kan transporten tilpasses de aktuelle krav. Endelig kan påtrykket 3 framstilles med kjente og vanlige trykkerimaskiner, såsom matrise-, laser- eller injektortrykkerimaskiner. in relation to the horizontal no influence on the result of the exploitation. The print 3 can also be placed under a clear, transparent foil, for example a shrink seal. As the transport speed of the piece goods is taken into account in the underestimation, the transport can be adapted to the relevant requirements. Finally, the overprint 3 can be produced with known and common printing machines, such as matrix, laser or injector printing machines.
