SauggreiferSuction cup
Die Erfindung bezieht sich auf einen manuell betätigten Sauggreifer zum Handhaben von glattflächigen Gegenständen.The invention relates to a manually operated suction gripper for handling smooth-surfaced objects.
Aus der glas- und blechverarbeitenden Industrie sind Sauggreifer bekannt, bei denen das zum Heben erforderliche Vakuum nicht direkt am Sauggreifer sondern an anderer Stelle z.B. durch eine Vakuumpumpe erzeugt wird, und der Sauggreifer über einen Schlauch mit dieser Vakuumquelle verbunden ist.Suction grippers are known from the glass and sheet metal processing industry in which the vacuum required for lifting is not generated directly on the suction gripper but elsewhere, e.g. by a vacuum pump, and the suction gripper is connected to this vacuum source via a hose.
Aus der gleichen Branche sind Sauggreifer bekannt, bei denen das zum Heben eines Gegenstandes erforderliche Vakuum durch das Bewegen der Saugmembran, das in der Regel durch eine Exzentermechanik bewerkstelligt wird, erzeugt wird. Der Exzenter-Hebel wird dabei über seinen oberen Totpunkt gebracht und verbleibt somit in einer Stellung in der die Saugmembran unter Vorspannung gehalten und das so erzeugte Vakuum erhalten bleibt.Suction grippers are known from the same industry, where the vacuum required to lift an object is generated by moving the suction membrane, which is usually achieved by an eccentric mechanism. The eccentric lever is moved past its top dead center and thus remains in a position in which the suction membrane is kept under pre-tension and the vacuum thus generated is maintained.
Sauggreifer mit fremderzeugtem Vakuum haben den Nachteil, daß zum einen eine Vakuumquelle, z.B in Form einer Vakuumpumpe mit Speicherkessel, erforderlich ist und zum anderen der Sauggreifer, bedingt durch die Schlauchverbindung zur Vakuumquelle, einen eingeschränkten Aktionsradius aufweist.Suction grippers with externally generated vacuum have the disadvantage that, on the one hand, a vacuum source, e.g. in the form of a vacuum pump with a storage tank, is required and, on the other hand, the suction gripper has a limited radius of action due to the hose connection to the vacuum source.
Bei Sauggreifern mit Exzentermechanik ist es nachteilig, daß diese in der Regel eine Zweihandbedienung (eine Hand zum Halten und Andrücken des Sauggreifers und die zweite Hand zum Betätigen des vakuumerzeugenden Exzenterhebels) erfordern und somit ein schneller Bewegungsablauf, wie er z.B. beim Umstapeln von BlechenThe disadvantage of suction grippers with eccentric mechanics is that they usually require two-handed operation (one hand to hold and press the suction gripper and the other hand to operate the vacuum-generating eccentric lever) and thus a fast movement sequence, such as when stacking sheets
benötigt wird, nicht möglich ist«is needed is not possible"
Ferner ist es bei dieser Art von Sauggreifern von Nachteil, daß beim Heben eines Gegenstandes ein sich durch undichten Sitz der Saugmembran reduzierendes Vakuum erst dadurch bemerkt wird, daß der gehobene Gegenstand plötzlich und ohne Vorankündigung abfällt.Another disadvantage of this type of suction gripper is that when lifting an object, a vacuum that is reduced due to a leaky fit of the suction membrane is only noticed when the lifted object suddenly falls down without warning.
Der Erfindung liegt die Aufgabe zu Grunde, die vorstehend genannten Nachteile von Sauggreifern der bekannten Art zu beseitigen, und einen Sauggreifer zu schaffen, der einfach herzustellen ist und ein schnelles und sicheres Handhaben von Gegenständen ermöglicht. The invention is based on the object of eliminating the above-mentioned disadvantages of suction grippers of the known type and of creating a suction gripper that is easy to manufacture and enables objects to be handled quickly and safely.
Erreicht ist dieses Ziel dadurch, daß die Saugmembran, die auf die Saugglocke geknüpft ist, über die Zugstange kraftschlüssig mit dem hebegriff verbunden ist. Eine bevorzugte Ausführungsform ist in den Ansprüchen 2 bis 5 gekennzeichnet.This aim is achieved in that the suction membrane, which is tied to the suction cup, is connected to the lifting handle in a force-fitting manner via the pull rod. A preferred embodiment is characterized in claims 2 to 5.
In der Zeichnung (Abb. 1 Sauggreifer) ist der Erfindungsgegenstand in einem Ausführungsbeispiel, im Bereich der Saugglocke und Saugmembran im Halbschnitt, dargestellt.In the drawing (Fig. 1 suction gripper) the subject matter of the invention is shown in an embodiment, in the area of the suction cup and suction membrane in half section.
Der Sauggreifer besteht aus dem Haltegriff 1, der über die beiden Holme 2 starr mit der Saugglocke 6 verbunden ist. Der Hebegriff ist in den beiden Holmen 2 geführt. Zwischen Saugglocke 6 und Saugmembran 7 ist eine Rückstellfeder 5 angeordnet. Der untere äußere Rand der Saugmembran 7 ist als Dichtlippe ausgebildet. Die dargestellte und beschriebene Ausführung ist nur ein Beispiel zur Realisierung der Erfindung.The suction gripper consists of the handle 1, which is rigidly connected to the suction bell 6 via the two bars 2. The lifting handle is guided in the two bars 2. A return spring 5 is arranged between the suction bell 6 and the suction membrane 7. The lower outer edge of the suction membrane 7 is designed as a sealing lip. The embodiment shown and described is only an example of the implementation of the invention.
Ein erfindungsgemäßer Sauggreifer ermöglicht durch die Anordnung von Hebegriff und Haltegriff eine Einhandbedienung beim Ansaugen und Absetzen von Gegenständen und somit einen schnellen und unkomplizierten Bewegungsablauf beim Handhaben von Gegenständen, wie er z.B. beim Verlegen von Kacheln verlangt wird. Da das zum Heben des Gegenstandes notwendige Vakuum durch Heranziehen des Hebegriffes an den Haltegriff erzeugt wird, bekommt der Benutzer des erfindungsgemäßen Sauggreifers unbewußt über seineA suction gripper according to the invention enables one-handed operation when sucking up and setting down objects through the arrangement of the lifting handle and handle, and thus a quick and uncomplicated movement sequence when handling objects, as is required, for example, when laying tiles. Since the vacuum required to lift the object is generated by pulling the lifting handle towards the handle, the user of the suction gripper according to the invention unconsciously receives
.".,•i. 4.".,•i. 4
Hand ständig eine Ruckmeldung darüber, ob sieh das Vakuum bei angehobenem Gegenstand durch Undichtigkeiten abbaut. Diese Rückmeldung merkt der Benutzer durch kontinuierliche Verringerung des Abstandes zwischen Hebegriff und Haltegriff bei gleichbleibender Betätigungskraft. Somit ist es dem Benutzer möglich, rechtzeitig vor dem Abfallen des angehobenen Gegenstandes entsprechende Gegenmaßnahmen einzuleiten.Hand constantly receives feedback about whether the vacuum is being reduced due to leaks when the object is lifted. The user notices this feedback by the continuous reduction of the distance between the lifting handle and the handle while the actuation force remains the same. This enables the user to take appropriate countermeasures in good time before the object falls.
Die Rückstellfeder beschleunigt die Rückstellung der Saugmembran in ihre Ruhelage und somit auch des Absetzen des Gegenstandes.The return spring accelerates the return of the suction membrane to its rest position and thus also the setting down of the object.
