Description
Beschrijving DiktemeterDescription Thickness gauge
Beschrijving en inrichting voor het snel meten van de dikte van gestapelde voorwerpen.Description and device for quickly measuring the thickness of stacked objects.
De uitvinding betreft een werkwijze en inrichting voor het 5 detecteren van intensiteitsverschillen, omvattende een stralingsbron of andere lichtbron, foto-elektrische detectie-middelen voor het detecteren van Intensiteitsverschillen in door een door de stralingsbundel bestraald voorwerp gereflecteerde straling, een verwerkingseenheid en postionerings-10 middelen. Werkwijzen en inrichtingen van bovengenoemde soort zijn bekend, bijvoorbeeld uit de Nederlandse octrooischriften 167530 en 1001637. Deze documenten beschrijven de werkwijzen en inrichtingen voor het tellen van gestapelde voorwerpen, zoals papier en karton of golfkarton. De uitvinding beoogt 15 gebruik te maken van deze telbare intensiteitsverschillen waarbij de gestapelde voorwerpen worden waargenomen door middel van optische hulpmiddelen en foto-elektrische detectiemiddelen, bijvoorbeeld een lineaire CCD-camera. Door het aantal voorwer-pen te tellen dat in het door de optische 20 hulpmiddelen gevormde beeld van de intensiteitsverschillen te onderscheiden valt en gebruik te maken van de hoogte van de stapel voorwerpen zoals waargenomen door de detectiemiddelen kan de gemiddelde dikte van de voorwerpen worden bepaald als zijnde de hoogte van het beeld gedeeld door het aantal 25 voorwerpen. Om de hoogte van het beeld te bepalen kan van verschillende methoden gebruik worden gemaakt. Het eenvoudigste middel is door de diktemeter in zijn geheel tegen de stapel voorwerpen te plaatsen zodat de hoogte van het beeld overeenkomt met de hoogte van het gezichtsveld op 30 een vaste afstand vanaf de optische hulpmiddelen. Indien het aanraken van de stapel ongewenst is kan men de diktemeter voorzien van hulpmiddelen om de afstand te meten. Een methode is gebruik te maken van een schuin invallende lichtbundel waarbij de afstand van de stapel tot de diktemeter kan 35 afleiden uit de positie van de gereflecteerde lichtbundel in het beeld van de camera (triangulatie). Het genereren van de s 2 lichtbundel kan door middel van een laser of andere lichtbron, LED of dergelijke, plaatsvinden, afhankelijk van de aard van de gestapelde voorwerpen en de gewenste afstand 5 tussen de dikteme-ter en de stapel voorwerpen.The invention relates to a method and device for detecting intensity differences, comprising a radiation source or other light source, photoelectric detection means for detecting Intensity differences in radiation reflected by an object irradiated by the radiation beam, a processing unit and postionation means . Methods and devices of the above-mentioned type are known, for example from Dutch patents 167530 and 1001637. These documents describe the methods and devices for counting stacked objects, such as paper and cardboard or corrugated cardboard. The invention has for its object to make use of these countable intensity differences in which the stacked objects are observed by means of optical aids and photoelectric detection means, for example a linear CCD camera. By counting the number of objects that can be distinguished from the differences in intensity in the image formed by the optical aids and by making use of the height of the stack of objects as observed by the detection means, the average thickness of the objects can be determined as being the height of the image divided by the number of 25 objects. Various methods can be used to determine the height of the image. The simplest means is to place the thickness meter in its entirety against the stack of objects so that the height of the image corresponds to the height of the field of view at a fixed distance from the optical aids. If touching the stack is undesirable, the thickness gauge can be equipped with tools to measure the distance. A method is to use a slanting incident light beam in which the distance from the stack to the thickness meter can be deduced from the position of the reflected light beam in the image of the camera (triangulation). The s 2 light beam can be generated by means of a laser or other light source, LED or the like, depending on the nature of the stacked objects and the desired distance between the thickness gauge and the stack of objects.
In een bepaalde uitvoering maakt de verwerkingseenheid zelf deel uit van de inrichting en worden de meetresultaten aan de gebruiker getoond door middel van daartoe geschikte middelen. In een bepaalde uitvoering maakt de verwerkingseenheid zelf 10 geen deel uit van de inrichting maar wordt een externe verwerkingseenheid (bijvoorbeeld een PC) gebruikt om de meetgegevens te verwerken en de gebruiker over het resultaat te informeren. Deze verwerkingseenheid zal in de eenvoudigste uitvoering door middel van geschikte bekabeling zijn 15 verbonden met de diktemeter. In die gevallen waarin het aanwezig zijn van bekabeling tussen de diktemeter en de uitwendige verwerkings-eenheid niet praktisch is kan de bekabeling worden vervangen door een communicatiesysteem waarbij gegevens van de diktemeter door middel van 20' elektromagnetische golven naar de verwerkings-eenheid worden verzonden.In a particular embodiment, the processing unit itself forms part of the device and the measurement results are shown to the user by means of suitable means. In a particular embodiment, the processing unit itself is not part of the device, but an external processing unit (for example a PC) is used to process the measurement data and to inform the user about the result. In the simplest embodiment, this processing unit will be connected to the thickness meter by means of suitable cabling. In those cases where the presence of cabling between the thickness gauge and the external processing unit is not practical, the cabling can be replaced with a communication system in which data from the thickness gauge is transmitted to the processing unit by means of 20 'electromagnetic waves.
Omdat de gemeten dikte van de voorwerpen afhankelijk is van de hoek tussen de lijn van de detectiemiddelen en de lijn van de voorwerpen dient hiervoor gecompenseerd te kunnen worden. 25 Of het nodig is een bepaalde uitvoering van de diktemeter van extra hulpmiddelen te voorzien ten einde hoekverdraaiing te compenseren hangt af van de nauwkeurigheidseisen van de gebruiker en de omstandigheden van de meting. Bij horizontaal gestapelde voorwerpen kan door middel van een versnellings-30 opnemer de zwaartekracht worden gemeten en kan de gebruiker worden geïnformeerd over afwijkingen ten opzichte van het waterpas, en kan de gebruiker door signalen worden geïnstrueerd de diktemeter anders te positioneren.Because the measured thickness of the objects depends on the angle between the line of the detection means and the line of the objects, it must be possible to compensate for this. Whether it is necessary to provide a particular embodiment of the thickness meter with additional aids in order to compensate for angular displacement depends on the accuracy requirements of the user and the circumstances of the measurement. With objects stacked horizontally, gravity can be measured by means of an acceleration sensor and the user can be informed about deviations from the spirit level, and the user can be instructed by signals to position the thickness gauge differently.
