Abstract

The invention relates to an apparatus for correcting the sabre during the punching of strips and taped components. Stresses are introduced into the strip, particularly by one-sided cutting and embossing processes during stamping and these stresses lead to strip curvature (sabre). In order to be able to perform correction of this sabre directly as the stamping process is being carried out, the invention envisages that the strip (8) should run through a measuring section, the entry and exit of which are formed by a guide (2) matched to the strip. Arranged approximately in the middle of the measuring section is a calliper gauge (3) supported in a low-friction manner, which is deflected as a function of the sabre of the strip. The degree of deflection is converted in an electronic measurement circuit (4) into an electrical signal, which is used to control a servo motor (5), the latter acting on a notching punch (7) in such a way as to correct the sabre. <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zur Korrektur der insbesondere beim einseitigen Stanzen von Bändern und gegurteten Teilen auftretenden Säbelkrümmung.The invention relates to a device for correcting the particular Saber curvature occurring when one-sided punching of tapes and taped parts.

Bedingt durch insbesonders einseitige Schneid- und Prägevorgänge beim Stanzen von Bän­ dern und gegurteten Teilen werden im Band vorhandene Spannun­ gen freigesetzt bzw. eingebracht. Diese Spannungen bewirken eine Bandkrümmung (Säbelkrümmung), die je nach Zustand des Ausgangsmaterials unterschiedlich ausfällt. Die Säbelkrümmung kann deshalb im Verlauf der Fertigung nicht durch ein konstan­ tes Korrekturglied ausgeglichen werden. Ein teilweiser Aus­ gleich konnte bisher lediglich durch einen manuell zustellbaren Kerbstempel zum Recken des Bandes in die Gegenrichtung erreicht werden. Nachteilig ist dabei jedoch, daß nur eine stichproben­ mäßige Prüfung erfolgt und daß die Korrekturintervalle sehr lang sind.Due to one-sided cutting and embossing processes when punching strips and belted parts are tension in the belt gene released or introduced. These tensions cause a band curvature (saber curvature), depending on the condition of the Starting material turns out differently. The saber curvature can therefore not in the course of production by a constant corrective element are compensated. A partial out So far, it was only possible to deliver it manually Notch stamp reached to stretch the tape in the opposite direction will. The disadvantage, however, is that only one sample moderate check is done and that the correction intervals are very are long.

Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrich­ tung zur automatischen Korrektur der einseitigen Säbelkrümmung beim Stanzen von Bändern und gegurteter Teile zu schaffen.The object of the present invention is therefore a Vorrich device for automatic correction of the one-sided saber curvature during punching of tapes and taped parts.

Zur Lösung dieser Aufgabe wird die Vorrichtung gemäß der Erfin­ dung derart ausgebildet, daß das Band eine Meßstrecke durch­ läuft, deren Einlauf und Auslauf durch eine auf das Band abge­ stimmte Führung gebildet ist, daß sich etwa in der Mitte der Meßstrecke ein reibungsarm gelagerter Meßschieber befindet, der abhängig von der Säbelkrümmung des Bandes ausgelenkt wird, daß der Grad der Auslenkung in einer elektronischen Meßschal­ tung in ein elektrisches Signal umgesetzt und damit ein Stell­ motor angesteuert wird, der auf einem Kerbstempel im Sinne der Korrektur der Säbelkrümmung einwirkt. To solve this problem, the device according to the inven dung formed such that the tape through a measuring section runs, the inlet and outlet by abge on the belt agreed leadership is formed approximately in the middle of the There is a caliper with low friction, which is deflected depending on the saber curvature of the band, that the degree of deflection in an electronic measuring scarf device converted into an electrical signal and thus a control motor is driven on a notch stamp in the sense acts on the correction of the saber curvature.  

Vorteilhaft ist es dabei, wenn die Einwirkung des Stellmotors auf den Kerbstempel über eine Vorrichtung zur Feineinstellung erfolgt.It is advantageous if the action of the servomotor on the notch stamp via a device for fine adjustment he follows.

Durch diese Maßnahmen wird eine kontinuierliche sofort wirksame Korrektur der Säbelkrümmung beim Stanzen von Bändern und der­ gleichen erreicht. Der Korrekturwert kann der Auslenksignal­ größe stufenlos angepaßt und damit entsprechend den Fertigungs­ bedingungen vorgewählt werden.Through these measures, a continuous is immediately effective Correction of the saber curvature when punching tapes and the same achieved. The correction value can be the deflection signal Steplessly adjusted size and thus according to the manufacturing conditions can be selected.

Anhand des Ausführungsbeispiels nach der Figur wird die Er­ findung näher erläutert.Based on the embodiment of the figure, the Er finding explained in more detail.

Das Band 1 durchläuft eine Meßstrecke, deren Einlauf und Aus­ lauf durch eine auf das Band abgestimmte Führung 2 gebildet wird. Etwa in der Mitte der Meßstrecke befindet sich ein rei­ bungsarm gelagerter Meßschieber 3 geringer Masse. Die im Band auftretende Säbelkrümmung übt auf den Meßschieber eine Quer­ kraft aus, wodurch dieser je nach Betrag der Säbelkrümmung ausgelenkt wird. Die Auslenkung wird durch eine elektronische Schaltung 4 abgefragt und in elektrische Signale, die in ihrer Größe dem Grad der Auslenkung entsprechen, umgesetzt. Der Korrekturwert kann dieser Auslenksignalgröße stufenlos im Faktor 1 bis 100 angepaßt werden. Mit diesem Signal wird der Stellmotor 5 angesteuert, der über eine Feineinstellung 6 die Zustellung des Kerbstempels 7 vornimmt und das Recken des Bandes 8 in die Gegenrichtung bewirkt.The tape 1 passes through a measuring section, the inlet and outlet is formed by a guide 2 matched to the tape. Approximately in the middle of the measuring section is a low-caliper caliper 3 with low mass. The saber curvature occurring in the band exerts a transverse force on the caliper, whereby this is deflected depending on the amount of saber curvature. The deflection is queried by an electronic circuit 4 and converted into electrical signals which correspond in size to the degree of deflection. The correction value can be infinitely adjusted to this deflection signal size in a factor of 1 to 100. With this signal, the servomotor 5 is actuated, which, via a fine adjustment 6, delivers the notch stamp 7 and causes the band 8 to be stretched in the opposite direction.
