Abstract

The object [10] is on a moving conveyor belt [11] and the edge is detected by a sensor [13] that is a distance [a] away from a line scanning camera [12]. This is less than the object length [b]. The sensor output triggers a measuring system[14] to determine the remaining length of the object to compensate for slippage on the belt.

Device for determining the length of objects moving past a line detection device, characterized in that a sensor ( 13 ) for detecting the start of the object is arranged at a predeterminable sensor distance (a) in the movement direction (A) behind the line detection device ( 12 ) , which is smaller than the object length (b), and that means ( 14 ) triggerable by a sensor signal are provided for triggering the measurement of a remaining length of the rear end region of the object ( 10 ) still passing the line detection device by means of the line detection device ( 12 ), wherein the object length (b) is the sum of the sensor distance (a) and the measured remaining length. 2. Vorrichtung zur Längenbestimmung von sich an einer Zei­ lenerfassungseinrichtung vorbeibewegenden Objekten, dadurch gekennzeichnet, dass ein Sensor (13) zur Erkennung des Objek­ tendes in einem vorgebbaren Sensorabstand (a) in der Bewe­ gungsrichtung (A) vor der Zeilenerfassungseinrichtung (12) angeordnet ist, der kleiner als die Objektlänge (b) ist, und dass jeweils durch ein Sensorsignal triggerbare Mittel (14) zur Beendigung der Messung einer Anfangslänge des Objekts (10) durch die Zeilenerfassungseinrichtung (12) vorgesehen sind, wobei sich die Objektlänge (b) als Summe des Sensorab­ stands (a) und der gemessenen Anfangslänge ergibt.2. Device for determining the length of objects moving past a line detection device, characterized in that a sensor ( 13 ) for detecting the object end is arranged at a predeterminable sensor distance (a) in the direction of movement (A) in front of the line detection device ( 12 ) , which is smaller than the object length (b), and that in each case means ( 14 ) which can be triggered by a sensor signal are provided for ending the measurement of an initial length of the object ( 10 ) by the line detection device ( 12 ), the object length (b) being Sum of the sensor distance (a) and the measured initial length results. 3. Vorrichtung nach Anspruch 1 oder 2, dadurch gekennzeich­ net, dass die Zeilenerfassungseinrichtung (12) als Zeilenka­ mera ausgebildet ist.3. Device according to claim 1 or 2, characterized in that the line detection device ( 12 ) is designed as a Zeilenka mera. 4. Vorrichtung nach einem der vorhergehenden Ansprüche, da­ durch gekennzeichnet, dass eine die Zeilenbreiten oder Pixel aufsummierende Einrichtung (14) zur Erfassung der Restlänge oder der Anfangslänge vorgesehen ist.4. Device according to one of the preceding claims, characterized in that a line sum or pixel summing device ( 14 ) is provided for detecting the remaining length or the initial length. 5.
