Abstract

The run of clockwork is tested with the first beat initiating the measurement till a predetermined number of subsequent beats is terminated. During the test the number of occurrences of a normal frequency is counted while any further beats are prevented from interfering during the blanking period. This procedure can be seen as a refinement of known method in which, after completion of a measuring step, a second one immediately follows with the same blocking time. Both results are then compared with each other. The present procedure decreases the time required by starting the beat(s) for subsequent stage(s) during the first stage. More subsequent stages for comparison increases the probability of accuracy of the test results.

Description

Die vorliegende Erfindung betrifft ein Verfahren zur Prüfung von Uhrwerken, bei welchem an jedem zu prüfenden Uhrwerk ein Satz von Gangmessungen durchgeführt wird, wobei jede dieser Gangmessungen von einem sie startenden Uhrenschlag an läuft und hernach nach einer vorbestimmten und stets gleichen Anzahl von Uhrenschlägen beendet wird.The present invention relates to a method for testing clockworks, in which to each A set of rate measurements is carried out for the watch movement under test, each of these rate measurements being carried out from the start of the clock, it runs and afterwards according to a predetermined and always the same one Number of clock strikes is stopped.

Jede dieser Gangmessungen kann zum Beispiel darin bestehen, zwischen dem sie startenden und dem sie beendenden Uhrenschlag die entsprechende Anzahl Perioden einer Normalfrequenz zu zählen. Bei einem bekannten Verfahren dieser Gattung wird zudem zwischen den beiden genannten Uhrenschlägen die Verarbeitung weiterer Uhrensehläge gesperrt, wobei allfällige während dieser Sperrzeit eintreffende Störimpulse von der Messung ferngehalten werden. Eine solche Messung dauert dann beispielsweise etwa 12 Sekunden.Each of these gait measurements can consist, for example, between the one they start and the one they ending clock strike counting the corresponding number of periods of a normal frequency. At a known method of this genus is also between the two mentioned clock strikes Processing of further clock slips blocked, with any interference pulses arriving during this blocking period be kept away from the measurement. Such a measurement then takes about, for example 12 seconds.

Obschon diese Sperre den Großteil der Störungen unwirksam macht, ergibt jeder außerhalb der Sperrzeit aufgenommene Störimpuls — sofern er nicht genau mit einem Uhrenschlag zusammenfällt — eine fehlerhafte Messung.Although this lock makes the majority of the disturbances ineffective, each results outside of the lock time recorded interference - if it does not exactly coincide with the stroke of a clock - a faulty one Measurement.

Man könnte nun diesesv bekannte Verfahren zu vervollkommnen trachten, indem man sofort nach Ende einer Messung eine zweite mit gleicher Sperrzeit anschließt und die beiden Ergebnisse miteinander vergleicht Diese Addition könnte fortgesetzt werden, wobei jede weitere Messung die Wahrscheinlichkeit erhöht, daß sich unter diesem Satz von Gangmessungen fehlerfreie befinden. Als Nachteil ergibt sich eine entsprechend lange GesamtmeßzeitOne could now endeavor to perfect this known method by immediately ending it A measurement with the same blocking time is followed by a second measurement and the two results together compares This addition could be continued, with each further measurement taking the probability increases that there are error-free under this set of rate measurements. The disadvantage is one correspondingly long total measuring time

Bei modernen Montageketten für Uhren sind zahlreiche Störgeräusche in ihrer Umgebung unvermeidlich; anderseits wird eine nach wenigen SekundenWith modern assembly chains for watches, numerous interference noises are inevitable in their surroundings; on the other hand, one becomes after a few seconds

ίο bemessene kurze Taktzeit der Kette angestrebt welche auch für die gesamte Messung des Ganges jeder montierten Uhr ausreichen muß. Diese gegensätzlichen Forderungen können mit Verfahren ähnlich den hier geschilderten nicht gleichzeitig erfüllt werden.ίο targeted short cycle time of the chain which must also be sufficient for the entire measurement of the rate of each assembled watch. These opposing Requirements similar to those described here cannot be met at the same time.

Es ist der Zweck der Erfindung, die erwähnten Mängel zu beheben. Demgemäß ist das erfindungsgemäße Verfahren dadurch gekennzeichnet daß noch innerhalb der ersten Gangmessung des Satzes alle weiteren Gangmessungen desselben Satzes durch unterschiedliche und innerhalb der ersten Gangmessung erfolgende Uhrensehläge gestartet werden.It is the purpose of the invention to remedy the mentioned shortcomings. Accordingly, the inventive Method characterized in that all of them are still within the first rate measurement of the set further gait measurements of the same set by different and within the first gait measurement occurring clock slips are started.

Durch diese Verschachtelung mehrerer Einzelmessungen in einen einzigen unterbruchslosen Gesamtmeßvorgang gelingt es, mit gegenüber einer Einzelmessung nur unwesentlich erhöhter Gesamtmeßzeit auch bei zahlreichen Störungen eine hohe Ausbeute an fehlerfreien Messungen zu erzielen.This nesting of several individual measurements in a single uninterrupted overall measurement process it is possible, with only slightly increased total measuring time compared to a single measurement, even with numerous faults to achieve a high yield of error-free measurements.

Im übrigen wird das erfindungsgemäße Verfahren an Hand der nachstehenden Zeichnung erläutert.In addition, the method according to the invention is explained with reference to the drawing below.

jo In der Zeichnung sind als Funktion der Zeit die fortlaufenden Uhrensehläge eines zu prüfenden Uhrwerkes veranschaulicht. Diese Uhrensehläge sind willkürlich von 10 bis 85 numeriert. Ferner ist in der Zeichnung angegeben, daß ein Satz von neun Gangmessungen g\ bis g9 durchgeführt werden soll.jo In the drawing, the continuous clock slips of a clockwork to be tested are illustrated as a function of time. These watch saws are randomly numbered from 10 to 85. It is also indicated in the drawing that a set of nine rate measurements g 1 to g 9 is to be carried out.

Gemäß diesem Beispiel läuft die erste Gangmessung g\ vom Uhrenschlag Nr. 14 bis zum Uhrenschlag Nr. 74. Nach der Erfindung läuft nun die zweite Gangmessung gi vom Uhrenschlag Nr. 15 bis zum Uhrenschlag Nr. 75, According to this example, the first rate measurement g \ runs from strike number 14 to strike number 74. According to the invention, the second rate measurement gi now runs from strike number 15 to strike number 75,

die dritte von Nr. 16 bis Nr. 76,
die vierte von Nr. 17 bis Nr. 77,
die fünfte von Nr. 18 bis Nr. 78,
die sechste von Nr. 19 bis Nr. 79,the third from No. 16 to No. 76,
the fourth from No. 17 to No. 77,
the fifth from No. 18 to No. 78,
the sixth from No. 19 to No. 79,

die siebente von Nr. 20 bis Nr. 80,
die achte von Nr. 21 bis Nr. 81the seventh from No. 20 to No. 80,
the eighth from No. 21 to No. 81

und die neunte und letzte des Satzes von Nr. 22 bis Nr. 82.
Durch dieses Verfahren ergibt sich eine erhebliche Zeitersparnis gegenüber den vergleichbaren bekannten Verfahren.and the ninth and last of the set from No. 22 to No. 82.
This process saves a considerable amount of time compared to the comparable known processes.
