Abstract

This invention relates to a gripping feeder for an intermittent feeding of strip or wire stock in presses, stamping machines or similar machines. It is an object of the invention to provide such gripping feeder which permits a change of the stroke length to be effected from the outside while the machine is in operation and permits such change to be effected manually or by means of an adjusting motor and also permits an automatic adaptation of the feeding and retaining grippers to the thickness of the strip or wire stock to be fed. This is accomplished in that the carriage carrying the feeding gripper is adapted to be driven from the main drive of the machine via a feed rocker, which extends transversely to the direction of travel of the carriage and is fulcrumed on a slider, which is slidable along a rail that extends transversely to the direction of travel of the carriage so that an adjustment of the slider along said rail will result in a change of the stroke length of the carriage. The feed rocker fulcrumed on the slider is preferably adapted to have an oscillating angular motion about its fulcrum imparted to it by a pivoted finger, to which an angular oscillation is imparted from the main drive, and which is pivoted to one arm of the feed rocker, the other arm of which is connected to the carriage by a link for imparting a reciprocating linear movement to the carriage.

Description

Die Erfindung bezieht sich auf eine Zangenvorschubeinrichtung zum intermittierenden Vorschub von Band- oder Drahtmaterial an Pressen, Stanzen od. dgl. Arbeitsmaschinen.The invention relates to a gripper feed device for the intermittent feed of strip or wire material on presses, punches or the like. Working machines.

Es sind Zangenvorschübe für diese Zwecke bekannt, welche von der Hauptwelle der Arbeitsmaschine aus über Winkeltriebe mit zwischenliegender Teleskopwelle im Maschinenrythmus angetrieben werden. Hierbei wirkt dieser Antrieb auf eine hin-und hergehender Transportzange, welche mit einer orstfesten Haltezange zusammenwirkt , wobei beide Zangen in ihrer öffnungs- und Schließbewegung gegenphasig gesteuert sind bei Schlittenanordnung der Transportzange hinter der Haltezange.Plier feeds are known for these purposes, which are driven from the main shaft of the working machine via angular drives with an intermediate telescopic shaft in the machine rhythm. In this case, this drive acts on a reciprocating transport tongs which cooperate with a stationary holding tongs, both opening and closing movements of the two tongs being controlled in opposite phase when the transport tongs are arranged behind the holding tongs.

Bei den bekannten Zangenvorschüben mit hin- und hergehendem Schlitten für den Zangentransport und stationärer Haltezange ist zur Einstellung der Vorschublänge ein Eingriff in die jeweilige Vorrichtung bei abgestelltem Lauf notwendig. Bei verschiedenem Produktionsbereich muß während des Laufens die Vorschublänge korrigiert werden, was hiermit nicht möglich ist.In the known pliers feeds with a reciprocating slide for the transport of pliers and stationary holding pliers, an intervention in the respective device when the barrel is switched off is necessary to adjust the feed length. In the case of different production areas, the feed length must be corrected while running, which is not possible with this.

Es ist nun Aufgabe der Erfindung eine Zangenvorschubeinrichtung zum intermittierenden Vorschub von Band- oder Drahtmaterial an Pressen, Stanzen od. dgl. Arbeitsmaschinen zu schaffen, welche die Verstellung der Vorschublänge von außen auch während des Betriebs erlaubt und zwar von Hand oder mittels Verstellmotor und überdies eine automatische Anpassung der Transport- und Haltezangen an die Materialdicke des vorzuschiebenden Band - oder Drahtmaterials ermöglicht.The object of the invention is a tong feed device for the intermittent feed of strip or wire material on presses, punches or. To create machines that allow the adjustment of the feed length from the outside even during operation by hand or by means of an adjustment motor and also enables automatic adjustment of the transport and holding tongs to the material thickness of the band or wire material to be fed.

Die Zangenvorschubeinrichtung zum intermitterenden Vorschub von Band- oder Drahtmaterial an Pressen, Stanzen od. dgl. Arbeitsmaschienn nach dem Oberbegriff des Anspruchs 1 kennzeichnet sich gemäß der Erfindung nun dadurch, daß der Schlitten mit der Transportzange über einen quer zur Schlittenbewegung liegenden Pendelrahmen - vom Gesamtantrieb - antreibbar ist und daß der Drehpunkt des Pendelrahmens durch einen Gleitstein gebildet ist, welcher auf einer Querschiene zum Schlitten zu dessen Hubverstellung verschiebbar ist, wobei der Pendelrahmen mit verstellbarem Gleitstein am einen Endlager vom Gesamtantrieb aus mittels hin- und herbewegtem Schwenkfinger in Pendelbewegung versetzbar ist und am zweiten Endlager über eine Lasche den Schlitten vor- und rückfahrbar hält.The pliers feed device for the intermittent feed of strip or wire material on presses, punches or the like. Working machines according to the preamble of claim 1 is characterized according to the invention in that the slide with the transport tongs via a pendulum frame transverse to the slide movement - from the overall drive - is drivable and that the fulcrum of the pendulum frame is formed by a sliding block, which is displaceable on a cross rail to the slide for its stroke adjustment, the pendulum frame with adjustable sliding block on one end bearing being able to be set in pendulum motion from the overall drive by means of a pivoting finger that is moved back and forth, second repository holds the slide forward and backward via a tab.

Durch Verstellung des Gleitsteins auf seiner Querschiene wird damit eine Einstellung der Vorschublänge während des Betriebs von außen ermöglicht und zwar manuell bzw. motorisch, z.B. mittels Spindelverstellung des Gleitsteins. So kann auch eine automatische Korrektur über ein Meßsystem mit Microrechner erfolgen.By adjusting the sliding block on its cross rail, it is thus possible to adjust the feed length from outside during operation, specifically manually or by motor, for example by means of spindle adjustment of the sliding block. An automatic correction can also be carried out via a measuring system done with microcomputer.

Im einzelnen kann ein Lagerarm am Schlitten den beweglichen Klemmbacken der Transportzange bilden und der Lagerarm durch einerseits auf einer Wippe abgestützten Kolben in Schließ- und Offenstellung bringbar sein, wofür eine auf diese Schließwippe andererseits wirkende, Kurvenscheibe über diese Wippe die Zangenöffnung steuert und eine Lagerrwippe am Vorrichtungsgehäuse den beweglichen Klemmbacken der Haltezange bildet, deren einer Wippenarm durch einerseits auf einer Wippe abgestützten Kolben in Schließ- und Offenstellung bringbar, wofür eine auf diese Schließwippe andererseits wirkende Kurvenscheibe über diese Wippe die Zangenöffnung steuert. Hierbei dient eine vom Gesamtantriebe getriebene Verstellwelle mit verschieb- und mitdrehbar aufsitzender Kurvenscheibe für die Betätigung der Transportzange und fest- und mitdrehbar aufsitzender Kurvenscheibe für die Betätigung der Haltezange gleichzeitig der Schlittenführung mit zusätzlich, paralleler Führungsstange, wobei die auf den Schließwippen abgestützten, in dem jeweiligen Lagerarm bzw. Wippenarm greifenden Kolben zum Schließen und Öffnen unter Zwischenschaltung von Druckfedern auf die Transport- bzw. Haltebacken wirken, um unabhängig von der Materialdicke deren Tansport- und Halteanlage zu erreichen.In particular, a bearing arm on the carriage can form the movable clamping jaws of the transport tongs and the bearing arm can be brought into the closed and open positions by pistons supported on a rocker, for which purpose a cam disc acting on this rocker on the other controls the pincer opening via this rocker and a bearing rocker on Device housing forms the movable clamping jaws of the holding pliers, one of which seesaw arm can be brought into the closed and open position by pistons supported on a rocker, for which purpose a cam disc acting on this closing rocker controls the opening of the pliers via this rocker. Here, an adjustment shaft driven by the overall drive with a cam plate that can be moved and rotated for the actuation of the transport pliers and a cam plate that is fixed and rotatable for the actuation of the holding pliers serves at the same time for the slide guide with an additional, parallel guide rod, the ones supported on the rockers in the respective one Bearing arm or rocker arm-engaging pistons act on the transport or holding jaws for closing and opening with the interposition of pressure springs, in order to achieve their transport and holding system regardless of the material thickness.

Der Antrieb der Zangenvorschubeinrichtung erfolgt von der Hauptwelle der Arbeitsmaschine aus über Winkeltriebe mit zwischenliegender Teleskopwelle im Maschinenrythmus zur Umsetzung in eine intermittierende Vorschubbewegung für ßand- oder Drahtmaterial 1. Hierfür sind eine hin- und hergehende Transportzange 2 mit den Klemmbacken 2a, 2b mittels Lagerarm 3 am Schlitten 4 und eine ortsfeste Haltezange 5 mit den Klemmbacken 5a, 5b mittels Lagerwippe 6 am Vorrichtungsgehäuse 7 vorgesehen. Der hin- und hergehende Antrieb des Schlittens 4 mit der Transportzange 2 erfolgt, wie insbes. aus Fig. 1 und 2 ersichtlich wird, vom Gesamtantrieb aus mittels Kurventrieb 8 mit hin- und herbewegtem Schwenkfinger 9 an das Endlager 9a des quer zur Schlittenbewegung liegenden Pendelrahmens 10 mit Gleitstein 11 als verschiebbarem Drehpunkt, wobei die Pendelbewegung als Hin- und Herbewegung sodann über die Lasche 12 am Endlager 12a und 12b an den Schlitten 4 weitergegeben wird. Der Gleitstein 11 ist nun mittels Spindel 13 über den Schieber 11a quer zum Schlitten 4 verschiebbar, wodurch sich der Pendelausschlag und damit die Vorschubbewegung des Schlittens 4 von außen, z.B. über einen Verstellmotor 14 des Laufs einstellen läßt. Hierfür kann im übrigen vermittels Meßsystem und Microrechner auch eine vorgebbare Einstellung und automatische Korrektur erreicht werden.The pliers feed device is driven from the main shaft of the working machine via angular drives with an interposed telescopic shaft in the machine rhythm for conversion into an intermittent feed movement for sand or wire material 1. For this purpose, a reciprocating transport pliers 2 with the clamping jaws 2a, 2b are used Bearing arm 3 on the carriage 4 and a stationary holding pliers 5 with the clamping jaws 5a, 5b are provided on the device housing 7 by means of a rocker 6. The reciprocating drive of the carriage 4 with the transport tongs 2 takes place, as can be seen in particular from FIGS. 1 and 2, from the overall drive by means of a cam drive 8 with a pivoting finger 9 which is reciprocated to the end bearing 9a of the pendulum frame lying transversely to the carriage movement 10 with sliding block 11 as a displaceable fulcrum, the pendulum movement then being passed on as a reciprocating movement via the tab 12 on the end bearings 12a and 12b to the carriage 4. The sliding block 11 can now be displaced transversely to the slide 4 by means of the spindle 13 via the slide 11a, as a result of which the pendulum deflection and thus the feed movement of the slide 4 can be adjusted from the outside, for example via an adjusting motor 14 of the barrel. For this purpose, a predeterminable setting and automatic correction can also be achieved by means of the measuring system and microcomputer.

Wie weiter aus der Zeichnung ersichtlich wird, bildet der Lagerarm 3 am Schlitten 4 den beweglichen Klemmbacken 2b der Transportstange 2, wobei der Lagerarm 3 durch einerseits auf einer Schließwippe 15 abgestützten Kolben 16 in Schließ- und Offenstellung bringbar ist, wofür eine auf diese Wippe 15 andererseits wirkende Kurvenscheibe 17 die Steuerung übernimmt. Weiter bildet die Lagerwippe 6 am Vorrichtungsgehäuse 7 den beweglichen Klemmbacken 5b der Haltebacken 5, wobei der eine Wippenarm 6a wiederum durch einerseits auf eine Schließwippe 18 abgestützten Kolben 19 in Schließ-und Offenstellung bringbar ist, wofür auch hier eine auf diese Wippe andererseits wirkende Kurvenscheibe 20 die Steuerung übernimmt.As can further be seen from the drawing, the bearing arm 3 on the slide 4 forms the movable clamping jaws 2b of the transport rod 2, the bearing arm 3 being able to be brought into the closed and open positions by pistons 16 supported on a rocker 15, for which purpose a rocker 15 on the other hand acting cam 17 takes control. Furthermore, the bearing rocker 6 on the device housing 7 forms the movable clamping jaws 5b of the holding jaws 5, one of which seesaws arm 6a can in turn be brought into closed and open positions by pistons 19 supported on a rocker 18, for which a cam 20 acting on this rocker also takes control.

Vom Gesamtantrieb aus wird über Zahnriemen 8a auch die Verstellwelle 21 angetrieben, auf welcher sowohl die verschieb- und mitdrehbare Kurvenscheibe 17 als auch die fest und mitdrehbare Kurvenscheibe 20 sitzt. Die Kurvenscheibe 17 wird durch einen Umlaufkugelkeil 22 verschieb- und mitdrehbar gehalten, wodurch die Verschiebbarkeit mit dem Schlitten gegeben ist, während die Kurvenscheibe 20 durch den Keil 23 fest und mitdrehbar gehalten ist, wodurch sich die Unverschiebbarkeit ergibt. Hierbei dient die Verstellwelle 21 mit der parallelen Führungsstange 24 gleichzeitig der Schlittenführung. Im übrigen sind die auf den Schließwippen 15,18 abgestützten, in den jeweiligen Lagerarm 3 bzw. Wippenarm 6a greifenden Kolben 16,19 zum Schlirßenanschlagbegrenzten und Öffnen.mit zwischengeschalteten/Druckfedern 25, 26 für die Transport- bzw. Haltebacken 2b, 5b ausgerüstet. Hiermit wird unabhängig von der Dicke des absatzweise vorzuschiebenden Band- oder Drahtmaterials 1 eine stets einwandfreie Transport- und Halteanlage erreicht, welche sich, wie erwünscht, bei starkem Material 1 infolge der eingesetzten Druckfedern 25,26 erhöht.From the overall drive, the adjusting shaft 21 is also driven via toothed belts 8a, on which both the displaceable and rotatable cam disk 17 and the fixed and rotatable cam disk 20 are seated. The cam disc 17 is held by a rotating ball wedge 22 so that it can be moved and rotated, so that the slider can be moved, while the cam 20 is held by the wedge 23 so that it cannot be moved. Here, the adjusting shaft 21 with the parallel guide rod 24 also serves to guide the slide. For the rest, the pistons 16, 19, which are supported on the locking rockers 15, 18 and which engage in the respective bearing arm 3 or rocker arm 6a, are equipped with intermediate / compression springs 25, 26 for the transport or holding jaws 2b, 5b for closing and opening. In this way, irrespective of the thickness of the strip or wire material 1 to be advanced in batches, an always perfect transport and holding system is achieved, which, as desired, increases with strong material 1 as a result of the compression springs 25, 26 used.

Weiterhin ist die Lagerwippe 6 am zweiten Wippenarm 6b ebenfalls durch einerseits auf einer Lüftwippe 27 abgestützten Kolben 28 in überlagerbare Offenstellung zur Lüftung der Haltezange 5 zu bringen, wofür eine andererseits auf die Lüftwippe 27 wirkende Kurvenscheibe 29, welche auch auf der Welle 21 sitzt, der Zangenöffnung zwecks Lüftung dient. Die Lüftwippe 27 ist vermittels Exzenterlagerung 30 über einen Betätigungskolben 31 aus-und einstellbar, wie dies aus Figur 7 ersichtlich wird. Der auf der Lüftwippe 27 abgestützte in den zweiten Wippenarm 6b greifende Kolben 28 ist-durch eine zwischengeschaltete Druckfeder 32 mit Wegbegrenzung 33 gehalten wo bei Betätigung der Lüftwippe 27 die Freigabe der Schließwippe 18 erfolgt. Eine Zwischenlüftung ist nur für Arbeiten mit Suchstiften zum Ausrichten des Bandmaterials erforderlich.Furthermore, the rocker 6 on the second rocker arm 6b is also on the one hand on a release to bring rocker-supported piston 28 into a superimposed open position for ventilation of the holding pliers 5, for which purpose a cam 29 acting on the rocker 27, which also sits on the shaft 21, serves to open the pliers for ventilation. The release rocker 27 can be turned and adjusted by means of an eccentric bearing 30 via an actuating piston 31, as can be seen in FIG. 7. The piston 28, which is supported on the rocker arm 27 and engages in the second rocker arm 6b, is held by an interposed compression spring 32 with travel limit 33, where the rocker switch 18 is released when the rocker arm 27 is actuated. Intermediate ventilation is only required when working with search pins to align the strip material.

Der vom Kurventrieb 8 bewegte Schwenkfinger 9 für den Pendelrahmen 10 hat Ruhephasen zwischen den wechselnden Pendelbewegungen, d.h. zwischen den hin- und hergehenden Bewegungen des Schlittens 4. Während diesen Ruhephasen bewirken die auf der Steuerwelle 21 vom Zahnriemen 8a getriebenen Kurvenscheiben 17,20 und 29 die wechselweise Betätigung der Transport- und Haltezange 2,5 über die Schließwippe 15,18 sowie die einschaltbare Lüftwippe 27. Durch Überdeckung der öffnungs- und Schließbewegungen der Zangen 2,5 in der Ruhephase ist eine sichere Bandklemmung gewährleistet. Schließlich sitzen die oberen festen Klemmbacken 2a, 5a, welche als Gegenhaltebacken der Transport-und Haltezange 2,5 wirken an Brücken 34,35 zur gemeinsamen Lüftung der Zangen 2,5 mittels pneumatisch betätigbarer Kolben 36,37, welche jeweils über Traversen 38,39 verbunden sind und über Federführungsbolzen 40 nach der Lüftung in Ausgangsstellung bringbar sind.The pivot finger 9 moved by the cam drive 8 for the pendulum frame 10 has rest phases between the alternating pendulum movements, ie between the reciprocating movements of the slide 4. During these rest phases, the cam disks 17, 20 and 29 driven by the toothed belt 8a on the control shaft 21 cause this alternate actuation of the transport and holding tongs 2.5 via the closing rocker 15, 18 and the switchable release rocker 27. By covering the opening and closing movements of the tongs 2.5 in the rest phase, a secure strap clamping is guaranteed. Finally, the upper fixed clamping jaws 2a, 5a, which act as counter-holding jaws of the transport and holding tongs 2.5, are located on bridges 34, 35 for the joint ventilation of the tongs 2.5 by means of pneumatically actuated pistons 36, 37, each of which has cross members 38, 39 are connected and can be brought into the starting position via spring guide pins 40 after ventilation.
