Description

Vorrichtung zum Ausstanzen von tiefgezogenen Formlingen aus thermoplastischem Kunststoff Die Erfindung bezieht sich auf Vorrichtungen zum Ausstanzen von tiefgezogenen Formlingen aus thermoplastischem Kunststoff mit innerhalb der Stanzmesser angeordneten, die Formlinge einrichtenden Formaufnahmen und Auswerfern für die ausgeschnittenen Formlinge. Device for punching out thermoformed moldings from thermoplastic Plastic The invention relates to devices for punching deep-drawn Moldings made of thermoplastic material with arranged inside the punching knife, the moldings setting up mold holders and ejectors for the cut-out ones Moldings.

Für das Abnehmen ausgestanzter Formlinge von der Formauflage oder Formaufnahme sind verschiedene Arten von Abstreifern bekannt, die hinter den Formling, insbesondere dessen Rand greifen und ihn rein mechanisch von der Formauflage bzw. Formaufnahme lösen. Diese bekannten Abstreifer lassen sich aber nicht mit der erforderlichen Betriebssicherheit verwenden, um Formlinge aus thermoplastischem Kunststoff aus einer Form aufnahme zu lösen. Für das genaue Ausrichten des Formlings gegenüber dem Stanzmesser muß eine verhältnismäßig feste Verbindung zwischen Formaufnahme und Formling geschaffen werden, die sich durch Abstreifer nicht mit Sicherheit lösen läßt. For removing punched moldings from the mold support or Different types of scrapers are known, which are behind the molding, in particular grip its edge and remove it mechanically from the mold support or Loosen the shape holder. These known wipers can not be with the required Use operational reliability to make moldings made of thermoplastic material a shape recording to solve. For the exact alignment of the molding opposite the punching knife must have a relatively firm connection between the form holder and molding are created that cannot be released with certainty by wipers leaves.

Andererseits können Formlinge aus thermoplastischem Kunststoff auch nicht allzu große Kräfte zum Ausstoßen aus den Formauflagen aufnehmen, ohne beschädigt zu werden. Dies gilt insbesondere für solche Formlinge, die durch Tiefziehen von Kunststoffolie dünnwandig ausgebildet sind. Auch mechanisch arbeitende Auswerfer, die sich auf Teile der Oberfläche des Formlings aufsetzen, können bei Formlingen aus thermoplastischem Kunststoff nicht Verwendung finden, weil durch sie die Formlinge zerdrückt werden können. On the other hand, moldings made of thermoplastic material can also be used do not absorb too large forces for ejection from the mold supports without being damaged to become. This applies in particular to those moldings that are made by deep drawing Plastic film are thin-walled. Mechanically working ejectors, that sit on parts of the surface of the molding, can in the case of moldings Made of thermoplastic material cannot be used because it causes the moldings can be crushed.

Das sichere und für den Formling schonende Lösen der verhältnismäßig festen Verbindung zwischen Formling und Formaufnahme wird durch die Erfindung dadurch erreicht, daß die Auswerfer als Bälge ausgebildet sind, die an eine Vakuumleitung und eine Preßluftleitung anschließbar sind. The safe and gentle release of the relatively fixed connection between molding and mold holder is achieved by the invention achieved that the ejectors are designed as bellows which are attached to a vacuum line and a compressed air line can be connected.

Durch die als Auswerfereinrichtungen benutzten Bälge werden eine Reihe wesentlicher Vorteile erzielt. The bellows used as ejector devices are a Achieved a number of significant advantages.

Die auf den Formling zum Lösen aus der Formaufnahme ausgeübte Kraft kann im Gegensatz zu den bekannten Auswerfern und Abstreifern jetzt auf eine große Fläche des Formlings verteilt werden. Die Bälge entfalten mit ihrem Druckmittel, insbesondere mit Druckluft, die auf die Formlinge auszuübende Kraft erst nach dem Aufsetzen auf die Formlinge und von diesem Augenblick an auch noch in zunehmender Weise. Hierdurch wird im Gegensatz zu dem stoß-oder ruckweisen Arbeiten der bekannten Einrichtungen das Lösen der Formlinge aus den Formaufnahmen besonders schonend und trotzdem wesentlich nachhaltiger und sicherer als bisher. Neben diesen besonderen Vorteilen ihrer Arbeitsweise sind die Bälge auch besonders billig und leicht austauschbar, und sie ermöglichen es, eine Stanzpresse unter Beibehaltung des Pressen-Oberteils in einfacher Weise auf Formlinge anderer Größe umzustellen. Da die Auswerferbälge im Gegensatz zu den bekannten mechanischen Auswerfern und Abstreifern keine Führungselemente in der Stanzpresse benötigen, können sie einfach mit dem ausgewechselten Messer- und Formaufnahmensatz in der Stanzpresse angebracht werden.The force exerted on the molding to release it from the mold receptacle In contrast to the well-known ejectors and wipers, it can now be used on a large scale Area of the molding can be distributed. The bellows unfold with their pressure medium, especially with compressed air, the force to be exerted on the moldings only after Put on the bricks and from this moment on even more Way. In contrast to the jerky or jerky operation of the known Facilities release the moldings from the mold receptacles particularly gently and nevertheless, much more sustainable and safer than before. Besides these special ones Advantages of the way they work, the bellows are also particularly cheap and easy to replace, and they make it possible to run a punch press while maintaining the press top in a simple way to switch to moldings of other sizes. As the ejector bellows In contrast to the known mechanical ejectors and scrapers, no guide elements in the punching press, they can simply be removed with the exchanged knife and die set are mounted in the punch press.

Besonders vorteilhaft können bei einer Mehrfachstanze die Stanzmeser, Formaufnahmen und Auswerferbälge an der Unterseite eines Stanzpressen-Oberteiles angebracht sein. Wenn dabei der Stanzpressen-Oberteil mit nach außen abgedichteten Rillen, welche die Bälge mit derVakuum-Preßluftleitung verbinden, versehen ist, ist es nicht einmal nötig, besondere Maßnahmen zum Anschließen der Bälge an die Druck- und Saugeinrichtung zu treffen. With a multiple punch, the punching knives, Mold receptacles and ejector bellows on the underside of a punch press upper part to be appropriate. When doing the punch press upper part with sealed to the outside Grooves that connect the bellows to the vacuum compressed air line, It is not even necessary to take any special measures to connect the bellows to the To meet pressure and suction device.

EineAusführungsform derErfindung wird an Hand der schematischen Zeichnung beschrieben. An embodiment of the invention is illustrated with reference to the schematic drawing described.

Das in Richtung des Pfeiles schrittweise vorwärtsbewegte Band 1 aus thermoplastischem Material mit den Formlingen 2 wird zwischen den hier die Schneideinrichtungen tragenden Stanzpressen-Oberteil 3 und den Stanzentisch 4 derart geführt, daß die Formkörper um ein weniges weiter in Richtung des Pfeiles zum Stillstand kommen, als es der Lage der Schneideinrichtungen entspricht. The tape 1 moved forward step by step in the direction of the arrow thermoplastic material with the moldings 2 is between the cutting devices here supporting punch press upper part 3 and the punching table 4 so that the Shaped body come to a standstill a little further in the direction of the arrow, than it corresponds to the position of the cutting devices.

Die Schneideinrichtungen bestehen aus den Stanzmessern 5 und den innerhalb der Stanzmesser 5 angeordneten büchsenartig ausgebildeten Formaufnahmen 6. Wird nun der Stanzpressen-Oberteil 3 mit den Schneidvorrichtungen nach unten gedrückt, so wer- den die Formlinge 2 von den unten etwas konisch zulaufenden Formaufnahmen 6 erfaßt und mit dem sie zusammenhaltenden Folienband 1 auf dem Stanzentisch 4 so verschoben, daß sie zentral innerhalb der Stanzmesser 5 zu liegen kommen. Dadurch ist Vorsorge dafür getroffen, daß die Formkörper bei dem darauffolgenden Niedergehen der Stanzmesser 5 ebenfalls zentral bzw. ihrem sonstigen Umriß entsprechend ausgeschnitten werden. Nach dem Ausstanzen, z. B. beimWiederhochgehen des Stanzpressen-Oberteiles 3, werden die an den Messern haftenden und in die Formaufnahmen 6 gepreßten Formlinge 2 durch Gummibälge 7 ausgeworfen und mit dem nächsten Transport der Folie 1 schrittweise zu einem Waren-Auffangbehälter oder dergleichen abgeführt. The cutting devices consist of the punching knives 5 and the bush-like shaped receptacles arranged within the punching knife 5 6. If the punch press upper part 3 with the cutting devices is now down pressed, then the moldings 2 from the bottom somewhat conical tapered form receptacles 6 detected and with the film tape holding them together 1 moved on the punching table 4 so that it is centrally located within the punching knife 5 come to rest. This ensures that the molded body at the subsequent fall of the punching knife 5 also centrally or their other Outline can be cut out accordingly. After punching out, e.g. B. when going up again of the punch press upper part 3, the ones sticking to the knives and into the form receptacles 6 pressed bricks 2 ejected through rubber bellows 7 and with the next transport the film 1 gradually removed to a goods collecting container or the like.

Gegenüber mechanischen Auswerfer-Vorrichtungen, wie sie in vielerlei Formen bekannt sind, haben die Bälge 7 aus Gummi oder anderem elastischem Material den Vorteil der Billigkeit und der leichten Austauschbarkeit für die Verwendung in anderen Schneidvorrichtungen. Vor allem legen sich die Bälge 7 schonend gegen die auszuwerfenden Formlinge2, so daß diese auch bei festem Sitz in den Formaufnah men 6 nicht während des Auswerfens beschädigt werden. Compared to mechanical ejector devices, as they are in many ways Shapes are known, have the bellows 7 made of rubber or other elastic material the advantage of cheapness and easy interchangeability for use in other cutting devices. Above all, the bellows 7 gently lie against each other the moldings to be ejected2, so that they are in the mold receptacle even if they are firmly seated men 6 cannot be damaged during ejection.

Der Stanzpressen-Oberteil 3 ist an seiner unteren Seite zweckmäßig waffelförmig unter Bildung kreuz-und querlaufender, bis zu den Bälgen 7 führender und im übrigen nach außen abgedichteter Kanäle 8 gerillt. The punch press upper part 3 is useful on its lower side waffle-shaped with the formation of criss-cross and transverse, leading up to the bellows 7 and grooved for the rest of the outwardly sealed channels 8.

Diese Kanäle 8 stehen über eine Bohrung 9 im Stanzpressen-Oberteils 3 und einen Schlauch 10 sowie einen Dreiwegehahn 11 wahlweise mit einer Vakuumleitung 12 oder einer Druckluftleitung 13 in Verbindung, so daß die Bälge 7 durch Vakuum zusammengezogen und andererseits durch Umstellen des Dreiwegehahnes 11 zum Auswerfen der Formlinge 2 kurzzeitig durch Preßluft ausgedehnt werden können.These channels 8 are via a bore 9 in the punch press upper part 3 and a hose 10 and a three-way valve 11 optionally with a vacuum line 12 or a compressed air line 13 in connection, so that the bellows 7 by vacuum contracted and on the other hand by changing the three-way valve 11 for ejection the moldings 2 can be briefly expanded by compressed air.

Die Vorrichtung ist im einzelnen verschiedener Abwandlungen fähig, ohne daß sich dadurch an dem Wesen der Erfindung etwas ändert. So kann der Stanzentisch 4 als die Folie 1 tragende und mitdem Durchmesser der Formlinge 2 entsprechenden Löchern versehene Schnittplatte aus Stahl oder dergleichen ausgebildet sein. Bei einer solchen Anordnung fallen die ausgestanzten und durch die Bälge 7 ausgestoßenen Formlinge 2 nach unten, wo sie gegebenenfalls übereinander gestapelt werden können. Zum Abstreifen der Restfolie von den Stanzmessern 5 können besondere Abstreifplatten am Stanzpressen-Oberteil 3 vorgesehen sein. The device is capable of various modifications in detail, without changing anything in the essence of the invention. So can the punching table 4 as supporting the film 1 and corresponding to the diameter of the molded articles 2 Cut plate provided with holes may be formed from steel or the like. at Such an arrangement, the punched out and ejected by the bellows 7 fall Moldings 2 down, where they can be stacked on top of each other if necessary. Special stripping plates can be used to strip the remaining film off the punching knives 5 be provided on the punch press upper part 3.
