Abstract:
To test the reliability of a testing apparatus which checks multiple objects of the same type for one set feature, generates a feature signal for each object and checks the feature signal with respect to fulfillment of one first set condition, a test object is inserted in the testing apparatus after multiple objects and the feature signal of the test object is checked with respect to the fulfillment of a second condition, the second condition being a feature signal of the test object which corresponds to a previously inputted reference value. The reference value can be inputted by storing the feature signal of a test object as reference value.
Abstract:
Zur Feststellung der Integrität eines in einem Behälter (10) befindlichen Produktes wird ein vorgegebenes Merkmal des Produktes in dem Behälter mittels einer ersten Messmethode (20) bestimmt, bei dem eine erste physikalische Eigenschaft des Produkts untersucht wird, wird das vorgegebene Merkmal zusätzlich mindestens noch direkt oder mittels einer zweiten Messmethode (30) ermittelt, die auf einer zweiten physikalischen Eigenschaft basiert, die von der ersten physikalischen Eigenschaft abweicht, und werden die mittels der beiden Messmethoden erhaltenen Werte des vorgegebenen Merkmals verglichen. Ist das Produkt ein Getränk in einer Flasche (10) und ist das vorgegebene Merkmal die Füllhöhe, so kann die erste Messmethode (20) darin besteht, dass die Füllhöhe mittels Absorption eines Röntgenstrahls gemessen wird, und kann die zweite Messmethode (30) darin besteht, dass die durch die Flasche bewirkte Änderung der Resonanzfrequenz eines Hochfrequenz-Schwingkreises gemessen wird.
Abstract:
To test the reliability of a testing apparatus which checks multiple objects of the same type for one set feature, a feature signal for each object is generated which is checked with respect to fulfillment of one first set condition, a test signal is derived from the feature signals of multiple objects and checked with respect to the fulfillment of a second condition. When checking if the test signal fulfils a second condition, the test signal can be compared with a reference value. The test signal may be the mean value of the feature signal of multiple objects.
Abstract:
Primary mechanical vibrations are generated in a container wall (12) to determine parameters in closed containers. The secondary vibrations caused by the primary mechanical vibrations of the container wall (12) in the container (10), which take place in the are between the closure (12) and the liquid, are recorded and analyzed, whereby the parameters are determined on the basis of recorded frequency progression of said vibrations. Further, the primary vibrations of the closure (12) can also be recorded and analyzed, whereby the inner pressure prevailing inside the container (10) can be determined on the basis of the frequency of said primary vibrations. The frequencies of the primary and secondary vibrations can be determined by conducting a frequency spectrum analysis. The secondary vibrations can be recorded independently from the primary vibrations so that only those vibrations occurring within a timed measurement window are recorded, within which the primary vibrations have already abated.
Abstract:
Containers (10) are conveyed past a device for inspecting the container bases for contamination, flaws and foreign bodies. The containers (10) are conveyed to the inspection device by a first conveyor (12) and removed by a second conveyor (16). A gap (14) is provided between the first and second conveyors (12, 16) within which the containers (10) are not supported, at least not on their entire standing surfaces. The containers (10) on the first conveyor (12), in the gap (14) and on the second conveyor (16) are led through lateral guide devices (24) and are conveyed at least in the gap (14) under pressure from behind.
Abstract:
In order to test the integrity of products in containers (10), several characteristics of the products are detected with physical measuring methods and a good-bad signal is produced on the basis of the measuring results, for which purpose several of the measuring results are placed in relation to each other, which can consist in the following: the deviations of the individual measuring results from a reference value, optionally after weighting and standardization are added up and the sum is compared to a threshold value. The measuring results can also form a multidimensional area in which one or several boundary surfaces separate the good value areas from the bad value areas.
Abstract:
Um Objekte (14) wie Behältern, Gebinden, Packstücken, unterschiedlicher Masse, mittels einer Ausleiteinrichtung (10) selektiv von einer ersten Transporteinrichtung (11) auf eine zweite Transporteinrichtung (12) auszuleiten, wird mittels einer Einrichtung (30, 32) das Fortschreiten der Ausleitung eines Objekts (14) ermittelt, wobei eine Steuereinrichtung (32) in Abhängigkeit von dem ermittelten Fortschritt der Ausleitung aktiviert wird, und zwar so, dass bei einem geringeren Fortschritt eine stärkere oder längere Aktivierung erfolgt und umgekehrt. Der Fortschritt der Ausleitung kann mittels eines Winkelgebers, eines Linear-Encoders, einer Geschwindigkeitsmessung oder eines Beschleunigungsgebers, die die für eine bestimmte Strecke oder zum Erreichen einer bestimmten Geschwindigkeit oder Beschleunigung erforderliche Zeit messen, oder mittels eines Kraftsensors, der die zum Bewegen des Objekts (14) erforderliche Kraft misst, erfolgen.
Abstract:
Objects (10) to be inspected, particularly empty beverage bottles, are conveyed on two conveyors (12, 14) which exhibit a mutual lateral separation and run at differing speeds so that the objects (10) rotate about their vertical axis. A bottom-inspection device (30, 32) is located within the gap between the conveyors (12, 14). A guiding railing (16) running in the direction of transport can be placed above the first, more slowly running conveyor (12).The objects (10) on the first conveyor stand on the edge strip between the guiding railing (16) and the edge of the first conveyor (12), and the width of this edge strip is up to approximately 1/3 of the diameter of the objects.
Abstract:
The device for selecting one or more rotationally symmetrical containers (11) from a stream of such containers (10) conveyed under pressure from behind comprises a first conveyor (12) for the container stream and a second conveyor (18) for removing the selected containers (11). The second conveyor (18) diverges from the first conveyor (12) at a removal point (16). The first conveyor (12) descends at a shallow angle from the removal point (16). A separator wedge (20) is provided between the first and second conveyors (12, 18). A first deflecting slider (22) is provided at the removal point (16) next to the first conveyor (12) on the side on which the second conveyor (18) diverges and can slide out towards the apex of the separator wedge (20). A second deflecting slider (24) is provided at the removal point (16) next to the first conveyor (12) on the side at which the first conveyor starts to descend and can slide out towards the apex of the separator wedge (20).
Abstract:
Rotationally symmetrical containers (10) are conveyed under dynamic pressure on a conveyer surface (12) bounded at the sides by rails (14). Rotation of the containers (10) at a predetermined location along the conveyer surface (12) is effected as follows: downstream of the location at which the containers are to be rotated, one of two consecutive containers (10) is arranged in a stable manner against one rail (14) and the second is arranged in a stable manner against the other rail (14).
