Description

Verfahren zum Lochen blattförmigen Guts sowie Vorrichtung zum Durchführen des Verfahrens Die Erfindung betrifft ein Verfahren zum Lochen blattförmigen Guts, wobei dieses mit einer Seite an einen mindestens einen vorspringenden Stempel aufweisenden Amboß angelegt wird und wobei Stempel und Gut gegeneinander gedrückt werden. Außerdem bezieht sich die Erfindung auf eine Vorrichtung zum Durchfiiliren des Verfahrens.Method for punching sheet-like material and device for carrying it through of the procedure The invention relates to a method for sheet-shaped punching Guts, this with one side to at least one protruding punch having an anvil is applied and wherein the punch and the goods are pressed against each other will. The invention also relates to a device for filtering of the procedure.

Verfahren der oben genannten Art sind bekannt und werden u.a.Methods of the above-mentioned type are known and are used, inter alia.

bevorzugt dafür angewendet, um Perforationen in Filitistreifen zu erzeugen, d.h. photographische Filinstreifen im Bereich eines oder beider Seitenränder mit einer Lochreihe zu versehen. Hierbei werden aus Stempel und Matrize bestehende Lochwerkzeuqe absatzweise betätigt,und das zu lochende Gut erfährt eine absatzweise Vorschubbewegung. Bei den bekannten Verfahren der erwähntem Art tritt der Nachteil auf, daß die erreichbare Arbeitsgeschwindigkeit niedriger ist als dies wünschenswert wäre. Ungünstig ist weiterhin, daß das zu lochende Gut, beispielsweise photographischer Film, nicht fortlaufend, sondern nur absatzweise bewegt werden kann. Zudem tritt bei den bekannten Verfahren eine nicht unbeträchtliche Verschmutzung durch den beim Lochen ausgeschnittenen Werkstoff auf. Auch gegensei-Li#e Ablösung von Schichten tritt häufig in der Nähe der Perforation photographischer Filme oder Papiere auf, wenn die Perforation durch Anwendung bekannter Lochungsververfähren erzeugt wird.Preferably used to make perforations in filiti strips produce, i.e. photographic strips of film in the area of one or both side edges to be provided with a row of holes. This consists of a punch and a die Perforation tool operated intermittently, and the material to be punched experiences a discontinuous operation Feed movement. In the known methods of the type mentioned, the disadvantage arises on that the achievable operating speed is lower than this is desirable were. It is also unfavorable that the material to be punched, for example photographic Film cannot be moved continuously, but only intermittently. Also occurs in the known method a not inconsiderable pollution by the when Punch cut out material. Also mutual removal of layers often occurs near the perforation of photographic film or paper, when the perforation is created using known punching techniques.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der in Rede stehenden Art zu schaffen, die es ermöglicht, blattförmiges Gut mit höherer Arbeitsgeschwindigkeit bei gleichzeitig verbesserter Betriebssicherheit ~#u ueben.The invention is based on the object of providing a device of the in To create the type in question, which makes it possible to produce sheet-like material with higher Working speed with simultaneously improved operational safety ~ # u practice.

Ausgehend von einem Verfahren der eingangs genannten Art ist diese Aufgabe erfindungsgemäß dadurch gelöst, daß Ultraschall-Schwingungsenergie von der dem Stempel abgekehrten Seite des Guts her diesem zugeführt wird. Es gelingt dadurch, wie nachfolgend anhand der ins einzelne gehenden Beschreibung eingehend erläutert wird, das blattförmige Gut bei vergleichsweise erhöhter Arbeitsgeschwindigkeit mit einem höchstmaß an Betriebssicherheit zu lochen. Besondere Vorteile ergeben sich, wenn es sich bei dem Gut um ein langgestrecktes bewegtes Band handelt.This is based on a method of the type mentioned at the beginning The object of the invention is achieved in that ultrasonic vibration energy from the the side of the good facing away from the stamp is fed to it. It succeeds as explained in detail below with reference to the detailed description is, the sheet-like material at a comparatively increased working speed with to punch holes with the highest level of operational safety. There are particular advantages if the good is an elongated moving belt.

Es ist nämlich dadurch, daß erfindungsgemäß Ultraschall-Schwingungsenergie auf die dem Stempel abgekehrte Seite des Bandes aufgebracht wird, möglich, dieses fortlaufend zusammen mit dem Stempel durch eine Zone hindurchzuführen, in der Schwingungsenergie wirksam ist. Eine absatzweise Bewegung des Bandes ist nicht erforderlich.Namely, it is due to the fact that according to the invention ultrasonic vibration energy is applied to the side of the tape facing away from the stamp, this is possible to pass continuously together with the punch through a zone in which the vibration energy is effective. Intermittent movement of the belt is not required.

Ganz besonders vorteilhaft ist es, wenn bei einem Ausführungsbeispiel. zum Lochen von Gut aus thermoplastischem Werkstoff~ Ultraschall-Schwingungsenergie in einem solchen Ausmaße aufgebracht wird, daß eine Erhitzung und En7eichung des Guts eintritt.It is particularly advantageous if in one embodiment. for punching goods made of thermoplastic material ~ ultrasonic vibration energy is applied to such an extent that heating and calibration of the Guts enters.

Bei einem weiteren vorteilhaften Ausführungsbeispiel wird an die vom Stempel abgekehrte Seite des Guts ein blattförmiger körper angelegt, und zumindest eine der aneinanderliegenden Oberflächen des Guts und des blattförmigen Körpers enthält einen thermoplastischen Stoff. Auch bei diesem Ausführungsbeispiel wird Ultraschall-Schwingungsenergie in einem sdchen Ausmaß aufgebracht, daß der thermoplastische Stoff erweicht wird. Dadurch wird bewirkt, daß durch die Erweichung des thermoplastischen Stoffs die aus dem Gut beim Lochen ausgeschnittenen Werkstoffstückchen an dem blattförmigen Körper haften, so daß der beim Lochen des Guts ausgeschnittene Abfall auf einfachste Weise zusammen mit dem blattförmigen Körper abgeführt werden kann. Dieses Ausführungsbeispiels des erfindungsgemäßen Verfahrens bietet eine praktisch völlige Sicherheit gegen die Gefahr einer Verschmutzung aufgrund des beim Lochen anfallenden Abfalls.In a further advantageous embodiment, the from A sheet-shaped body is applied to the stamp facing away from the property, and at least one of the abutting surfaces of the good and the sheet-like body contains a thermoplastic material. Also in this embodiment Ultrasonic vibrational energy is applied to the extent that the thermoplastic Fabric is softened. This causes by softening the thermoplastic Substance, the pieces of material cut out of the material during the punching process on the sheet-shaped Bodies stick, so that the waste cut out when punching the material can be removed in the simplest way together with the leaf-shaped body. This embodiment of the method according to the invention offers a practical one complete security against the risk of contamination due to the punching generated waste.

Der das Haften der Abfallstückchen an dem blattförmigen Körper bewirkende thermoplastische Stoff kann durch die Oberfläche des zu lochenden Guts gebildet sein, wenn das Gut aus thermoplastischem Material besteht. Dies ist beispielsweise der Fall, wenn als zu lochendes Gut photographischer Film aus einem thermoplastischen Kunstharz Verwendung findet. Hierbei kann als blattförmiger Körper beispielsweise ein Papierblatt verwendet werden.That causes the debris to adhere to the sheet-like body thermoplastic material can be formed by the surface of the material to be punched be if the goods are made of thermoplastic material. This is for example the case when the material to be punched is a photographic film made of a thermoplastic Resin is used. Here, as a sheet-like body, for example a sheet of paper can be used.

Der Erfindung liegt auch die Aufgabe zugrunde, eine einfach aufgebaute Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens zu schaffen.The invention is also based on the object of a simply constructed To create apparatus for performing the method according to the invention.

Erfindungsgemäß ist diese Aufgabe bei einer Vorrichtung mit einem an das zu lochende Gut anlegbaren Amboß mit mindestens einem aus dessen Oberfläche vorspringenden Stempel und mit einer Einrichtung zum Aneinanderdrücken von Stempel und Gut dadurch zu - durch gelöst, daß die Einrichtung zum Aneinanderdrücken von Gut und Stempel ein Ultraschall-Schwingungsenergie abgebendes Ultraschallhorn aufweist und daß der Stempel und das Horn auf verschiedenen Seiten des Guts angeordnet sind.According to the invention, this object is in a device with a to be placed on the good to be punched anvil with at least one of its surface protruding stamp and with a device for pressing stamps together And good to - solved by that the device for pressing together Well and stamp has an ultrasonic horn that emits ultrasonic vibration energy and that the punch and the horn are arranged on different sides of the property.

Vorzugsweise ist ein hohler Stempel vorgesehen, dessen seinen Hohlraum umgebende Wandung in eine Schneid>#ante ausläuft.Preferably, a hollow punch is provided, its cavity surrounding wall ends in a cutting edge.

Bei einem weiteren Ausführungsbeispiel ist der Amboß kreiszylindrisch geformt und relativ zum Horn drehbar gelagert/ und eine Mehrzahl von Stempel sind in gegenseitigem Abstand am Umfang des Amboß angeordnet. Das letztgenannte ausführunqs beispiel eignet sich besonders dazu, um in photographischen Filmbändern oder Papierbändern mit hoher Arbeitsgeschwindigkeit eine Perforation zu erzeugen.In a further embodiment, the anvil is circular-cylindrical shaped and rotatably mounted relative to the horn / and a plurality of punches are spaced apart on the circumference of the anvil. The latter execution example is particularly suitable for use in photographic film tapes or paper tapes to generate a perforation at high operating speed.

Hierbei kann jeder der Stempel im Amboß radial verschiebbar angeordnet sein und es kann eine Verschiebeeinrichtung zum Bewegen der Stempel vorgesehen sein.Here, each of the punches can be arranged radially displaceably in the anvil and a displacement device for moving the stamp can be provided.

Als Verschiebeeinrichtung sind bei einer weiteren Abwandlung des ltztgenannten Ausführungsbeispiels ein auf die Stempel einwirkender feststehender Nocken und je eine jedem Stempel zugeordnete Feder zur Bildung eines Kraftschlusses zwischen Nocken und Stempel vorgesehen.In a further modification of the last-mentioned Embodiment a fixed cam acting on the stamp and each a spring assigned to each punch to form a frictional connection between cams and stamp provided.

Bei einem weiteren Ausführungsbeispiel weist das Horn eine Nut für die Aufnahme der Enden der das Gutddirchdringenden Stempel auf.In a further embodiment, the horn has a groove for the inclusion of the ends of the stamps penetrating the property.

Die Anordnung kann weiterhin so getroffen sein, daß in den inneren Hohlraum jedes Stempels ein relativ zum Amboß radial unverschiebbar angeordneter Finger eingreift. Dieser Finger dient dazu, um ein im hohlen Stempel sitzendes, ausgeschnittenes Werkstoffstückchen auszuwerfen, wenn der betreffende Stempel nach Durchdringen des Guts radial nach einwärts relativ zu dem unverschiebbar angeordneten Finger bewegt wird.The arrangement can also be made so that in the inner The cavity of each punch is arranged such that it cannot be displaced radially relative to the anvil Finger intervenes. This finger is used to pick up a Eject cut pieces of material if the relevant punch after Penetration of the material radially inwards relative to the immovable Finger is moved.

Vorteilhaft ist eine Einrichtung zum Ab führen der beim Lochen aus dem Gut ausgeschnittenen Werkstoffstückchen vorgesehen.A device to lead from the punching is advantageous the end the well cut out pieces of material provided.

Als Einrichtung zum Abführen der Werkstoffstückchen kann ein blattförmiger, an die dem Horn benachbarte Seite des Guts anlegbarer Körper vorgesehen sein, an dem die ausgeschnittenen Werkstoffstückchen des Guts haften. Der blattförmige Körper mit den an ihm haftenden Werkstoffstückchen oder Abfallstückchen braucht zum Beseitigen des Abfalls hierbei lediglich nach dem Lochen vom Gut abgenommen und einer Abfallsammeleinrichtung zugeführt werden.A sheet-shaped, be provided on the side of the material which can be placed on the side of the material adjacent to the horn to which the cut-out pieces of material of the goods adhere. The leaf-shaped body with the bits of material or pieces of waste adhering to it needs to be removed of the waste in this case only removed from the goods after punching and a waste collection device are fed.

Die Erfindung wird im folgenden anhand von in den Zeichnungen dargestellten Ausführungsbeispielen im einzelnen erläutert.The invention is illustrated below with reference to in the drawings Embodiments explained in detail.

durch drehend Hierbei wir«, da die Erfindung sehr gut für das Erzeugen von Perforationen in photographischem Material geeignet ist und da auch mehrere der Ausführungsbeispiele den Anwendungsfall des Perforierens photographischen Materials zeigen, von "Performieren" oder Perforation gesprochen. Die letztgenannten Ausdrücke beziehen sich jedoch nicht nur auf das Erzeugen von fortlaufenden Reihen aus gleichen und in gleichen gegenseitigen Abständen angeordneten Löchern, wie dies bei der Filmperforation der Fal ist, sondern sollen auch das Erzeugen einzelner Löcher oder dergl. bezeichnen. by turning Here we «because the invention is very good for generating of perforations in photographic material is suitable and there also several of the exemplary embodiments the application of perforating photographic material show, spoken of "performing" or perforation. The latter expressions however, do not just relate to the creation of contiguous series from equals and equally spaced holes as in the film perforation the fal is, but are also intended to denote the creation of individual holes or the like.

Fig. 1 zeigt einen Amboß 11 aus einem harten festen Werkstoff ~beispielsweise aus Stahl oder einem anderen Metall.Fig. 1 shows an anvil 11 made of a hard solid material - for example made of steel or another metal.

Innerhalb einer Bohrung in dem Amboß 11 ist ein hohler Stempel 13 angeordnet, der sich über die Oberseite des Amboß um eine Strecke hinaus erstreckt, die gleich oder etwas größer ist als es der Dicke eines zu perforierenden Bandes 15 entspricht. Ein Ultraschallhorn 17 ist so angeordnet, daß es mit seiner Unterseite in der Nähe der Oberseite des Bandes 15 verläuft, so daß, wenn das Horn 17 unter Einfluß eines Ultraschallgenerators, der von beliebiger bekannter Art sein kann, rasch aufwärts und abwärts schwingt, das Band 15 über den Stempel 13 herabgedrückt wird, wobei gleichzeitig eine Erhitzung des Bandes stattfindet. Hierdurch wird im Band eine Lochung bewirkt, das Band also perforiert.A hollow punch 13 is located within a bore in the anvil 11 arranged that extends beyond the top of the anvil by a distance, which is equal to or slightly greater than the thickness of a tape to be perforated 15 corresponds. An ultrasonic horn 17 is arranged so that it is with its underside runs near the top of the belt 15 so that when the horn 17 is under Influence of an ultrasonic generator, which can be of any known type, swings rapidly up and down, the band 15 pressed down over the punch 13 is, at the same time a heating of the tape takes place. As a result, the The tape creates a perforation, i.e. the tape perforates.

Ultraschallgeneratoren und Ultraschallhörner, die für den vorliegenden Verwendungszweck geeignet sind, sind bekannt und in zahlreichen Veröffentlichungen beschrieben, beispiel weise in den USA-PS 3 495 104 und 3 022 814.Ultrasonic generators and ultrasonic horns used for the present Intended use are known and in numerous publications described, for example in U.S. Patents 3,495,104 and 3,022,814.

Im allgemeinen schwingen solche Ultraschallgeneratoren in einem Frequenzbereich bis zu 80 Kilohertz, also beispielsweise mit einer Schwingungsfrequenz von 20 oder 40 Kilohertz, wobei die Schwingungsamplitude zwischen 0,025 mm und 0,12 mm beträgt, jedoch auch geringer oder größer sein kann. Der U1-traschallgenerator ist an einer nicht dargestellten Halterung gelagert, die es ermöglicht, daß das Horn 17, im Gegensatz zu einer starren Lagerung, nach abwärts gleiten kann, so daß das Horn etwas nach unten fällt, wenn das Band 15 über den Stempel 13 nach unten gebracht wird, Es wäre jedoch auch eine starre Lagerung des Ultraschallgenerators inöglich, weil auch durch die Schwingungsbewegung des Endes des Horns 17 allein eine Perforierung des Bandes eintritt.In general, such ultrasonic generators vibrate in a frequency range up to 80 kilohertz, for example with an oscillation frequency of 20 or 40 kilohertz, with the oscillation amplitude between 0.025 mm and 0.12 mm, however, it can also be smaller or larger. The U1 ultrasonic generator is on one mount, not shown, which allows the horn 17, in contrast to a rigid bearing, can slide downwards, so that the horn is slightly behind falls down when the tape 15 is brought down over the punch 13, it would be however, a rigid mounting of the ultrasonic generator is also impossible, because also through the vibratory motion of the end of the horn 17 alone perforates the band entry.

Der Stempel 13 kann jede gewünschte Form haben, so daß er mit seinem offenen Ende Löcher von kreisrunder, rechteckiger oder anderer Form nach Wunsch erzeugt.The stamp 13 can have any desired shape, so that he with his open end holes of circular, rectangular or other shape as desired generated.

Fig. 2 zeigt ein Ausführungsbeispiel, das dazu geeignet ist um eine Perforation in Form einer Reihe von in gleichem#ge-.Fig. 2 shows an embodiment that is suitable for a Perforation in the form of a series of in the same # ge.

genseitigem Abstand angeordneten Löchern in einem langen Band zu erzeugen, beispielsweise in einem photographischen Filmstreifen oder Papierstreifen. Schnelle und ununterbrochene Arbeitsweise wird dadurch erreicht, indem man einen Amboß 21 kreiszylindrischer Form vorsieht, der so angeordnet ist, daß er in der Nachbarschaft des zugekehrten Endes eines Horns 23 dauernd umläuft, um ein langes Band 25 aus photographischem Film oder aus Papier dauernd an dem Horn vorbeizuführen.to create mutually spaced holes in a long band, for example in a photographic film strip or paper strip. Fast and uninterrupted operation is achieved by using an anvil 21 circular cylindrical shape, which is arranged so that it is in the vicinity the facing end of a horn 23 continuously revolves around a long band 25 photographic film or paper to constantly pass the horn.

Der zylindrische Amboß 21 trägt eine Mehrzahl von in gleichen gegenseitigen Abständen angeordnete%sich radial erstreckenden Stempeln 27, die nacheinander auf das Horn 23 ausgerichtet werden, wenn der kreiszylindrische Amboß sich dreht. Außerdem wird, wenn sich der~Amboß 21 entgegen dem Uhrzeigersinn (Blickrichtung entsprechend Fig. 2) dreht, jeder Stempel 27 aus einer Ausgangsstellung, in der sein Ende mit der Zylindermantelfläche des Amboßes 21 bündig ist, radial nach auswärts bewegt, so daß, wenn der betreffende Stempel an dem Horn 23 vorbeiläuft, dieser ausreichend weit nach außen radial vorsteht,um bei der gegebenen Dicke des Bandes 25 dieses zu durchdringen.The cylindrical anvil 21 carries a plurality of in like mutual Spaced% radially extending punches 27, which one after the other the horn 23 can be aligned as the circular cylindrical anvil rotates. aside from that when the anvil 21 moves counter-clockwise (line of sight accordingly Fig. 2) rotates, each punch 27 from an initial position in which its end with the cylindrical surface of the anvil 21 is flush, moved radially outward, so that when the punch in question passes the horn 23, this is sufficient protrudes radially outward to the given thickness of the band 25 this to penetrate.

Bei der weiteren Drehbewegung des Amboß 21 wird jeder Stempel 27, wenn er aus dem Bereich des Horns 23 abläuft, noch weiter radial nach auswärts bewegt, so daß sichergestellt wird, da völliges Durchdringen durch das Band eintritt. Anschließend bewegt sich dann jeder Stempel 27 wieder radial nach einwärts bis zu der zurückgezogenen Ausgangsstellung.As the anvil 21 continues to rotate, each punch 27, if it runs out of the area of the horn 23, moves even further radially outward, so that it is ensured that full penetration occurs through the tape. Afterward then each punch 27 moves radially inward again up to the retracted one Starting position.

Die radiale Bewegung der Stempel 27 wird durch Berührung der inneren Enden der Stempel mit einem exzentrischen feststehend angeordneten Nocken 29 bewirkt, der innerhalb des Amboß 21 angeordnet ist.Jeder Stempel ist durch eine Schraubenfeder 31 für die Bewegung in die zurückgezogene Ausgangsstellung vorgespannt.Die Feder 31 stützt sich mit ihrem äußeren Ende an der Innenwandung eines Rings 32 ab, der den Mantel des kreiszylindrischen Ambosses 21 bildet. Mit den inneren Enden stützen sich die Federn 31 an je einem an jedem Stempel 27 befestigten Bund 33 ab. Jede Schraubenfeder 31 ist in einem Zwischenraum zwischen dem äußeren Ring 32 und einem inneren kreiszylindrischen Ring 34 untergebracht.The radial movement of the punch 27 is achieved by touching the inner Causes ends of the punch with an eccentric fixed cam 29, which is located inside the anvil 21. Each punch is supported by a helical spring 31 preloaded to move to the retracted starting position. The spring 31 is supported with its outer end on the inner wall of a ring 32, the forms the jacket of the circular cylindrical anvil 21. Support with the inner ends the springs 31 each on a collar 33 attached to each punch 27. Every Coil spring 31 is in a space between the outer ring 32 and a inner circular cylindrical ring 34 housed.

Um sicherzustellen, daß die von jedem hohlen Stempel 27 ausgeschnittenen Materialstückchen sich nicht innerhalb des Stempels festsetzen, ist jedem Stempel, wie dies in Fig. 3 gezeigt ist, ein stationärer Finger 37 zugeordnet, der im Ring 32 befestigt ist und der sich durch einen in Langsrichtunc des Stempels verlaufenden Schlitz 39 hindurch erstreckt, der in dem Stempel 27 ausgebildet ist. Bei diesem Aufbau#wIrd, wenn der Stempel 27 sich nach auswärts bewegt,unter Einwirkung des Horns 23 das Band perforiert und ein ausgeschnittenes Stückchen des Bandmaterials kann eventuell innerhalb des Stempels zurückbleiben. Wenn jedoctl anschließend sich der Stempel radial nach einwärts bewegt, dann wirft der Finger 37 das Naterialstückchen aus dem Innenraum des Stempels 27 aus. Die ausgeschnittenen Materialstückchen (sowohl diejenigen, die von sich aus vom Stempel abfallen, als auch diejenigen, die durch die Finger 37 ausgeworfen werden) werden sämtliche aus dem Bereich des Bandes mittels Saugeinrichtungen 43 und 43' abgesaugt oder mittels eines Luftstrahls entfernt. Es können auch die Zähne eines Zahnrads oder andere Einrichtunqen vorgesehen sein, die mechanisch in die in dem Band gebildeten Löcher eingreifen, um die ausgeschnittenen Werkstoffstückchen zu entfernen, Wie aus den Fig. 2 und 4 zu entnehmen ist, hat die untere Stirnfläche des Horns 23 etwa die gleiche Krümmung wie der Umfang des kreiszylindrischen Amboß 21, ist an seinen äußeren Rändern abgerundet,um eine Beschädigung des Bandes zu vermeiden1 und weist eine flache Nut 45 auf, durch die ein Raum für die Aufnahme jedes der Stempel 27 geschaffen wird, nachdem diese das Band durchdrungen haben und sich durch das Band hindurch etwas nach außen erstrecken.To make sure that the cut out from each hollow punch 27 Pieces of material do not get stuck inside the stamp, every stamp, as shown in Fig. 3, a stationary finger 37 associated with that in the ring 32 is attached and which extends through a longitudinal direction of the stamp Slot 39 extends therethrough, which is formed in the punch 27. With this one Structure # wIrd, when the punch 27 moves outwards, under the action of the Horns 23 perforated the tape and a cut out piece of the tape material may remain inside the stamp. If jedoctl then the punch moves radially inward, then the finger 37 throws the piece of material from the interior of the stamp 27. The cut out pieces of material (both those who fall off the stamp of their own accord, as well as those who pass through fingers 37 are ejected) are all out of the area of the tape by means of Suction devices 43 and 43 'sucked off or removed by means of an air jet. The teeth of a gear wheel or other devices can also be provided, which mechanically engage in the holes formed in the tape to make the cut out Bits of material to remove, As can be seen from FIGS. 2 and 4, has the lower end face of the horn 23 has approximately the same curvature as the circumference of the circular cylindrical anvil 21, is rounded at its outer edges to prevent damage to the tape avoid1 and has a shallow groove 45 through which a space for the reception each of the punches 27 is created after they have penetrated the tape and extend slightly outward through the band.

Wie aus Fig. 5 hervorgeht,ist der kreiszylindrische Amboß 21 über Speichen 47 mit einer Welle 49 verbunden, die durch einen Motor M gedreht wird, um den der Stempel 27 nacheinander zur Ausrichtung auf das Horn 23 zu bringen, das an einem Ultraschallgenerator 51 bekannter Art angebracht ist. Der in Fig. 5 nicht gezeiqte exzentrische Nocken 29 ist auf einer feststehenden Achse 55 befestigt, die von einem stationären Traggestell 57 getragen wird, das auf der dem Motor M abgekehrten Seite des Amboß 21 angeordnet ist.As can be seen from Fig. 5, the circular cylindrical anvil 21 is over Spokes 47 connected to a shaft 49 which is rotated by a motor M, in order to bring the punch 27 one after the other to align on the horn 23, the is attached to an ultrasonic generator 51 of known type. The one in Fig. 5 does not eccentric cam 29 shown is attached to a fixed axis 55, which is carried by a stationary support frame 57 which is supported on the motor M remote side of the anvil 21 is arranged.

Bei dem in Fig. 6 gezeigten Ausführunqsbeispiel ist das U1-ist traschallhorn 23' kreiszylindrisch geformt und/so angeordnet, daß es sich bei der Drehung des Amboß 21 zusammen mit diesem dreht. Zu diesem Zweck kann das Horn 23' so gelagert sein, wie dies beispielsweise in der USA-PS 3 201 864 beschrieben ist.In the embodiment shown in FIG. 6, the U1 is traschallhorn 23 'shaped as a circular cylinder and / so arranged that it is during the rotation of the Anvil 21 rotates along with this. For this purpose, the horn 23 'can be mounted in this way as described, for example, in US Pat. No. 3,201,864.

Bei dem vorliegenden Aus führungsbeispiel schwingt das Horn 23' in einer parallel zur Drehachse des Amboß 21 verlaufenden Richtung.In the present exemplary embodiment, the horn 23 'swings in a direction parallel to the axis of rotation of the anvil 21.

Sowohl das Horn 23 als auch das Horn 23' sind ausreichend weit von dem Amboß 21 entfernt, um zu ermbglichen, daß das zu perforierende Band in den Bereich zwischen Horn und Amboß eintreten kann.Both horn 23 and horn 23 'are sufficiently far from removed from the anvil 21 to allow the tape to be perforated to enter the area can occur between horn and anvil.

Anstatt das Band mit jedem Stempel vollständig zu durchdringen, kann auch so vorgegangen werden, daß ~ zu dem Zeitpunkt, wo der betreffende Stempel direkt dem Horn er gegenübersteht, /das Band fast völlig durchdrungen hat (beispielsweise das Band zu 950 durchdrungen hat). Völlige Durchdringung erfolgt bei einem solchen Vorgehen bei der anschließenden ~weiteren, radial nach außen verlaufenden Bewegung des betreffenden Stempels ~nachdem dieser an dem Bereich des Horns vorbeigelaufen ist. Bei diesem Vorgehen kann eine Bertihrung zwischen dem Horn und dem betreffenden Stempel vermieden werden.Instead of completely penetrating the tape with each punch, you can also be proceeded in such a way that ~ at the point in time when the relevant stamp directly the horn he is facing / has almost completely penetrated the band (for example has penetrated the tape to 950). Complete penetration occurs in such a case Procedure for the subsequent ~ further, radially outward movement of the stamp in question ~ after it has passed the area of the horn is. With this procedure, a contact between the horn and the concerned Avoid stamps.

In den Fig. 7 und 8 ist ein Amboß 111 aus hartem und festem Material dargestellt, beispalsweise aus Stahl oder einem anderem Metall. In Bohrungen des Amboß 111 sind hohle Stempel 113 angeordnet, die -# über die Oberseite hinaus um eine Strecke vorspringen, die gleich oder etwas größer ist als die Dicke eines zu perforierenden Blattes 115. Ein zweites Blatt 116 ist auf der Oberseite des Blattes 115 angeordnet und dient dem Zweck, ausgeschnittene Werkstoffstückchen von dem Blatt 115 abzuführen. Ein Ultraschallhorn 117 ist so angeordnet, daß seine untere Fläche in der Nähe der Oberseite des zweiten Blattes 116 verläuft,- so daß, wenn das Horn 117 schnell unter Einwirkung eines Ultraschallgenerators bekannter Art aufwärts und abwärts schwingt, das Horn die Blätter 116 und 115 nach abwärts gegen den Stempel 113 zwingt, wobei gleichzeitig eine Erhitzung des Blattes 115 an der dem Stempel 113 zugekehrten Seite hervorgerufen wir und eine Lochung des Blattes 115 eintritt, wobei ein ausgeschnittenes Werkstoffstückchen 118 anfällt.In Figs. 7 and 8, an anvil 111 is made of hard and strong material shown, for example made of steel or another metal. In bores of the Anvil 111 are hollow punches 113 arranged around the - # over the top protrude a distance that is equal to or slightly greater than the thickness of a to perforating sheet 115. A second sheet 116 is on top of the sheet 115 arranged and serves the purpose of cutting out pieces of material from the sheet 115 to pay off. An ultrasonic horn 117 is arranged so that its lower surface runs near the top of the second sheet 116 - so that when the horn 117 rapidly upwards under the action of an ultrasonic generator of a known type and swings downward, the horn swings blades 116 and 115 downward against the punch 113 forces, at the same time a heating of the sheet 115 on the stamp 113 is caused by the side facing and a perforation of the sheet 115 occurs, whereby a cut-out piece of material 118 is obtained.

Soll nur ein einziges Loch in dem Blatt erzeugt werden, dann ist das Horn 117 stationär angeordnet, Soll eine Vielzahl von Löchern erzeugt werden, dann kann auf beliebige geeignete Weise eine Relativbewequng zwischen dem Horn 117 und den Blättern 115 und 116 über aufeinanderfolgende Stempel 113 durchgeführt werden, indem man beispielsweise das Horn 117 in der durch einen Pfeil angedeuteten Richtung bewegt oder indem man den Amboß mit den Blättern unter dem Horn 117 vorbeibewegt.If only a single hole is to be created in the leaf, then this is it Horn 117 is arranged in a stationary manner. If a large number of holes are to be produced, then can in any suitable manner a relative movement between the horn 117 and the blades 115 and 116 carried out via successive punches 113 be, for example, the horn 117 in the indicated by an arrow Direction or by moving the anvil with the blades under the horn 117.

Um eine Beschädigung der Blätter bei einer solchen Bewegung zu vermeiden, weist das Horn 117 an einem Rand eine Abschrägung 117a auf, und es ist auch von Vorteil, wenn das Horn 177 an seiner Unterseite 117b eben ausgebildet ist, wobei die Ebene der Unterseite etwas gegenüber der Ebene der Oberseite des Amboß 111 in Beweaunqsrichtung des Horns relativ zum Amboß geneigt verläuft, beispielsweise unter einem spitzen Winkel von 1 bis 1,50, um die Reibung zwischen dem Horn und dem Blatt 116 zu verringern, wenn das Horn fortschreitend über die Vorderkante und anschließend über die Hinterkante des Stempels 113 läuft. Das Horn 117 kann die gleichen Eigenschaften aufweisen, wie dies bei den vorstehend in Bezug auf die Fig. 1 und 2 beschriebenen Hörnem 17 und 23 der Fall ist.To avoid damaging the blades during such a movement, the horn 117 has a chamfer 117a on one edge, and it is also of Advantage if the horn 177 is flat on its underside 117b, wherein the plane of the bottom slightly opposite the plane of the top of the anvil 111 in Beweaunqsrichtung the horn relative to the anvil runs inclined, for example below an acute angle of 1 to 1.50 to reduce friction between the horn and the reed 116 decrease as the horn progresses over the leading edge and subsequently runs over the rear edge of the punch 113. The horn 117 can have the same properties have, as in the case of those described above with reference to FIGS. 1 and 2 Horns 17 and 23 is the case.

Der Stempel 113 kann jede gewünschte Form haben, so daß sein offenes Ende Löcher von kreisrunder,rechteckiger oder beliebiger anderer Form bildet. Vorteilhafterweise-ist der Stempel außen kreiszylindrisch, hohl und weist am offenen Ende geneigt zur Längsachse verlaufende Innenflächen auf, so daß am offenen Ende ein kegelstumpfförmiger Innenraum gebildet wird, wobei der eingeschlossene Kegelwinkel beispielsweise ungefähr 300 beträgt, und daß eine scharfe Schnittkante 113a gebildet wird, wie dies in Fig. 8 gezeigt ist. Der geneigte Verlauf der Innenwände bewirkt, daß das Werkstoffstückchen 118 gegen das zweite Blatt 116 gedrückt wird, wo es haftet.The punch 113 can have any desired shape, so that its open Forms holes of circular, rectangular or any other shape at the end. Advantageously-is the punch is circular-cylindrical on the outside, is hollow and at the open end is inclined to the longitudinal axis extending inner surfaces, so that a frustoconical interior space at the open end is formed, the included cone angle for example approximately 300 is, and that a sharp cutting edge 113a is formed, as shown in Fig. 8 is shown. The inclined course of the inner walls causes the piece of material 118 is pressed against the second sheet 116 where it adheres.

Das unter Bezug auf die Figuren 7 und 8 beschriebene Vorgehen wurde mit Erfolg dazu verwendet, um bei Verwendung eines photographischen Films vom Azetat-Typ und Poly-(Athylentherephtalat) Typ als Blatt 115 im Film Berforationen verschiedenster Form zu erzeugen. Die Stärke des als Blatt 115 dienenden Films betrug 0,06 bis 0,25 mm, wobei Papier als Werkstoff für das Blatt 116 verwendet wurde, dessen Stärke etwa in dem selben Abmessungsbereich lag. Es wurden beispielsweise kreisrunde Löcher mit einem Durchmesser von 2,54 mm und rechteckige Löcher mit den Abmessungen 1,4 auf 2,03 mm erzeugt. Der Stempel 113 trat mit seiner scharfen Schnittkante 113a ungefähr o,o5 mm in das Papier ein und das Werkstoffstückchen 118 wurde mit-dem Papier durch die an den geneigt verlaufenden Innenwänden des Stempels wirksame U1-traschallenergie verklebt oder verschweißt.The procedure described with reference to FIGS. 7 and 8 was carried out has been used successfully when using an acetate type photographic film and poly (ethylene terephthalate) type as sheet 115 in the film perforations of the most varied To create shape. The thickness of the film serving as sheet 115 was 0.06 to 0.25 mm, paper being used as the material for the sheet 116, its thickness was roughly in the same range of dimensions. For example, there were circular holes with a diameter of 2.54 mm and rectangular holes with the dimensions 1.4 produced to 2.03 mm. The punch 113 entered with its sharp cutting edge 113a about 0.05 mm into the paper and the piece of material 118 was with the Paper through the U1 -trasonic energy effective on the inclined inner walls of the stamp glued or welded.

Fig. 9 zeigt das Aussehen der Blätter 115 und 116, wenn diese in Bandform vorliegen, nachdem die Perforation des Blattes 115 durchgeführt ist und die kegelstumpfförmigen Stückchen 118 an dem Blatt 116 haften, so daß sie anschließend zusammen mit dem Blatt 116 abgeführt werden können.Fig. 9 shows the appearance of sheets 115 and 116 when they are in ribbon form are present after the perforation of the sheet 115 is carried out and the frustoconical Pieces 118 adhere to the sheet 116 so that they are then together with the Sheet 116 can be removed.

Fig. 10 zeigt ein Ausführungsbeispiel, das dazu geeignet ist, um eine Perforation in Form von Reihen von in gleichen gegenseitigen Abständen angeordneten Löchern in einem langen bandförmigen Gut zu erzeugen, indem eine Relativbewegung zwischen Ultraschallhorn und dem Band durchgeführt wird, bei dem es sich beispielsweise um photographischen Film oder um Papier handeln kann. Schneller und ununterbrochener Arbeitsablauf wird dadurch erreicht, daß man einen kreiszylinderförmigen Amboß 121 vorsieht, der sich in der Nähe eines Ultraschallhorns 123 dreht und über den ein langes Band 125 aus photographischem Film oder aus Papier dauernd geführt wird, so daß es an dem Horn vorbeiläuft Der Amboß 121 trägt eine Vielzahl von in gleichen gegenseitigen Abständen angeordneten hohlen Stempeln 127, die sich radial nach auswärts erstrecken und die nacheinander auf das Horn 123 ausgerichtet werden, um das lange Band 125 zu peforieren, wenn dieses fortlaufend an dem erregten Horn 123 vorbeiläuft. Gleichzeitig wird zusammen mit dem Band 125 in dem Raum zwischen dem Band 125 und dem Horn 123 ein zweites Band 129 geführt, das beim Ausführungsbeispiel aus Papier besteht und dazu dient, um ausgeschnittene Werkstoffteilchen 130 vom Band 125 abzuführen.Fig. 10 shows an embodiment which is suitable for a Perforation in the form of rows of equally spaced apart To create holes in a long band-shaped material by moving a relative movement between the ultrasonic horn and the tape, which is for example photographic film or paper. Faster and more uninterrupted The workflow is achieved in that a circular cylindrical anvil 121 provides that rotates near an ultrasonic horn 123 and over the one long tape 125 of photographic film or paper is continuously guided, so that it passes the horn The anvil 121 carries a plurality of equally spaced hollow punches 127, which extending radially outward and aligned sequentially with the horn 123 to pierce the long ribbon 125 when it is continuously energized Horn 123 passes by. At the same time, together with the belt 125 in the space between the band 125 and the horn 123, a second band 129 out, which in the embodiment consists of paper and is used to remove cut material particles 130 from Volume 125 to be discharged.

Die#Bänder 125 und 129 laufen über getriebene Rollen, die so angeordnet sind, daß die beiden anfänglich voneinander getrennten Bänder zusammengeführt werden und anschließend wieder auseinanderqeführt werden, um die auscreschnittenen Werkstoffteilchen zu entfernen, Der Amboß 121 kann unmittelbar angetrieben sein oder kann seinen Antrieb durch die Bewegung der Bänder 125 und 129 erhalten.The # belts 125 and 129 run over driven rollers arranged in this way are that the two initially separated bands are brought together and then moved apart again to remove the material particles that have been cut out To remove, the anvil 121 can be directly driven or can be its drive obtained by moving the belts 125 and 129.

Die Stirnfläche des Horns 123 ist zur Anpassung an die Oberfläche des Amboß 121 leicht gekrümmt und weist am vorderen Rand eine Abschrägung 123a auf, um eine Beschädigung der Bänder zu vermeiden.The face of the horn 123 is to conform to the surface of the anvil 121 is slightly curved and has a bevel 123a on the front edge, to avoid damaging the tapes.

Anstatt ein undrehbar angeordnetes Horn 123 zu verwenden, kann für das Perforieren auch ein kreiszylindrisches drehbares Horn Verwendung finden, wie es in Fig. 6 gezeigt und vorstehend beschrieben wurde.Instead of using a non-rotatable horn 123, for perforating also find a circular cylindrical rotatable horn use, such as it has been shown in Fig. 6 and described above.

Das unter Bezug auf die Fig. 7 bis 10 beschriebene Vorgehen läßt sich zum Perforieren blattförmigen oder bandförmigen Materials verschiedenster Art anwenden, sofern nur eine der BerUh~rungsflächen der aneinander liegenden Blätter oder Bänder einen thermoplastischen Werkstoff aufweist, der durch die Ultraschallschwingungen erweicht wird, so daß die aus dem ersten Blatt oder Band ausgeschnittenen Werkstoffstückchen an dem zweiten Blatt oder Band haften. Bei dem Blatt 115 oder dem Band 125 kann es sich um thermoplastischen photographischen Film handeln, beispielsweise aus Zelluloseazetat, Polyäthylen, Polypropylen, Polyvinylazetat, Polyvinylchlorid, einem Kopolymer aus Polyvinylazetat und -chlorid, Polyvinilidenchlorid oder Poly (äthylent-erephthalat). Das zweite Blatt 116 oder das zweite Band 129 sind im allgemeinen aus Papier. Einer oder beide der aneinanderliegenden Teile könnte jedoch auch aus nichtthermoplastischem Werkstoff bestehen, beispielsweise aus Metall oder Papier, der mit einer dünnen Beschichtung in Form eines thermoplastischen Harzes an der Oberfläche überzogen ist, die die Fläche des anderen Teils berührt, beispielsweise aus aus Polyäthylen oder/einem der anderen thermoplastischen, oben erwähnten Stoffe.The procedure described with reference to FIGS. 7 to 10 can be carried out use sheet-like or tape-like material of various kinds to perforate, if only one of the contact surfaces of the sheets or ribbons lying next to one another has a thermoplastic material, which by the ultrasonic vibrations is softened so that the pieces of material cut out of the first sheet or tape adhere to the second sheet or tape. The sheet 115 or the band 125 can it is thermoplastic photographic film, for example made of cellulose acetate, Polyethylene, polypropylene, polyvinyl acetate, polyvinyl chloride, a copolymer made of Polyvinyl acetate and chloride, polyvinylidene chloride or poly (ethylene terephthalate). The second sheet 116 or tape 129 is generally made of paper. One or both of the abutting parts could, however, also be made of non-thermoplastic material Material consist, for example of metal or paper, with a thin Coating in the form of a thermoplastic resin coated on the surface that touches the surface of the other part, for example made of polyethylene or / one of the other thermoplastic substances mentioned above.

Das Perforieren mit Ultraschall bietet wichtige Vorteile.Perforating with ultrasound offers important advantages.

nur Es ist hierbei nämlich/ein Stempel oder ein hohler Schneiddorn erforderlich, es wird jedoch keine mit hoher Cenauigkeit zu schleifende Matrize benötigt. only it is here namely / a punch or a hollow cutting mandrel required, but it does not become a die to be ground with high accuracy needed.

In Fällen, bei denen das zu perforierende Gut aus thermoplastischem Werkstoff besteht, wird die Beanspruchung und die Reibung zwischen Stempel und zu hearbeitendem Gut sehr stark verringert, weil die Ultraschallenergie eine durchgehende Plastifizieruna in diesem Material hervorruft. Der Stempel dringt fortschreitend in Material ein, das im Bereich von im vorderen bis zum hinteren Rand des. zu bildenden Lochs vorher erweicht wird, wenn die leicht geneigt verlaufende Oberfläche des mit hoher Frequenz schwingenden Horns den Arbeitsbereich bestreicht.In cases where the material to be perforated is made of thermoplastic Material exists, the stress and the friction between punch and too The working material is very much reduced because the ultrasonic energy is a continuous Plasticization in this material causes. The stamp penetrates progressively in material that ranges from the front to the rear edge of the. to be formed Lochs before is softened when the slightly inclined Surface of the horn vibrating at high frequency sweeps the work area.

Bei den in den Fig. 7bis 10 gezeisten und unter Bezug auf diese Figuren beschriebenen Ausführunasbeispiele tritt der zusätzliche Vorteil auf, daß das zweite Blatt oder das zweite Band, an dem die ausgeschnittenen werkstoffstückchen haften, als Puffer zwischen dem Stempel und der Ultraschallquelle dienen und daher eine Berührung zwischen dem Stempel und dem Ultraschallhorn verhindern In den Ausführungsbeispielen gemäß den Fig. 7 bis 10 sind feststehende Stempel gezeigt. Es versteht sich jedoch, daß hewegbare Stempel, wie es unter Bezug auf die Ausführungsbeispiele gemäß den Fig. 2 bis 4 beschrieben wurde, anstelle der feststehenden Stempel Verwendung finden könnten und daß auch der in Fig. 2 gezeigte Ausbildung des drehbaren Amboß mit bewegbaren Stempeln für das Ausführungsbeispiel gemäß Fig. 10 übernommen werden könnte.In those shown in FIGS. 7 to 10 and with reference to these figures Embodiments described has the additional advantage that the second Sheet or the second tape to which the cut-out pieces of material adhere, serve as a buffer between the stamp and the ultrasonic source and therefore a Prevent contact between the punch and the ultrasonic horn in the exemplary embodiments 7 to 10, fixed stamps are shown. It goes without saying, however, that hewable stamp, as it is with reference to the embodiments according to Fig. 2 to 4 has been described, find use instead of the fixed stamp could and that also the embodiment of the rotatable anvil shown in Fig. 2 with movable Stamping for the embodiment of FIG. 10 could be adopted.
