Description
Die Erfindung betrifft eine Transportvorrichtung mit einer Transportbahn zum Abführen von Werkstücken aus einer Schneidoder Stanzvorrichtung gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a transport device with a Transport track for removing workpieces from a cutting or Punching device according to the preamble of claim 1.
Aus der EP 338 297 A2 ist eine Transportvorrichtung bekannt geworden, über welche kreisrunde Werkstücke, die mit minimalem Stanzabfall aus einer Bahn ausgestanzt werden, in Spalten und Reihen zueinander ausgerichtet werden. Diese ausgerichteten Werkstücke können nun auf einfache Weise geschichtet und verpackt werden.A transport device is known from EP 338 297 A2 over which circular workpieces with minimal Punching waste is punched out of a web, in columns and Rows are aligned with each other. This aligned Workpieces can now be easily layered and be packed.
Aus der DE 33 09 525 C2 und der DE 31 14 718 C2 ist eine Transport- und Stapeleinrichtung für Blechzuschnitte bekannt geworden, bei der die Blechzuschnitte über eine Transportbahn in einen Auslagestern übergeben werden. Dabei werden die Blechzuschnitte jedoch stark abgebremst und beschleunigt, was bei Blechzuschnitten nicht unbedingt von Nachteil ist, bei anderen, insbesondere empfindlichen Materialien zu vermeiden ist. Sollten mit einer derartigen Vorrichtung Wattepads transportiert werden, so könnten diese beschädigt oder zumindest verformt werden. Diese Vorrichtung ist daher nicht oder nur bedingt für derartige Werkstbeke geeignet.From DE 33 09 525 C2 and DE 31 14 718 C2 is one Transport and stacking device for sheet metal blanks known become, in which the sheet metal blanks on a conveyor be handed over to a delivery star. The Sheet metal cuts, however, slowed down and accelerated what is not necessarily a disadvantage when cutting sheet metal to avoid other, especially sensitive materials is. Should cotton pads with such a device transported, they could be damaged or at least be deformed. This device is therefore not or only conditionally suitable for such workpieces.
Ausgehend von der DE 31 14 718 C2 liegt der Erfindung daher die Aufgabe zugrunde, eine Transportvorrichtung bereitzustellen, mit der Werkstücke problemlos und möglichst ohne Beschädigung angesammelt werden können, so dass sie einer Verpackungsmaschine zugeführt werden können.The invention is therefore based on DE 31 14 718 C2 the task of providing a transport device, with the workpieces without problems and if possible without Damage can be accumulated, making it one Packaging machine can be fed.
Diese Aufgabe wird erfindungsgemäss mit einer Transportvorrichtung gelöst, die die Merkmale des Anspruchs 1 aufweist.According to the invention, this object is achieved with a transport device solved, which has the features of claim 1.
Die Ausgestaltung der erfindungsgemässen Transportvorrichtung hat den wesentlichen Vorteil, dass die Werkstücke von der Transportbahn bei gleichbleibender Geschwindigkeit in die Transport- und Führungseinheit übergeben werden, und dadurch im Gegensatz zu einer beschleunigten oder gebremsten Übergabe schonender behandelt werden. Ausserdem wird durch Anlage der Transport- und Führungseinheit an die Oberseite und/oder an die Unterseite des Werkstücks eine gezielte Führung erzielt, so dass das Werkstück exakt im Auslagestern plaziert wird. Die Werkstücke werden also in die Aufnahmen des Auslagesterns schonender hineingeführt als beim Stand der Technik.The design of the transport device according to the invention has the main advantage that the workpieces are of the Transport track at constant speed in the Transport and management unit are handed over, and thereby in contrast to an accelerated or slowed transfer be treated more gently. In addition, the Transport and guidance unit on the top and / or on the underside of the workpiece achieves targeted guidance, so that the workpiece is placed exactly in the delivery star. The Workpieces are therefore in the recordings of the display star introduced more gently than in the prior art.
Da die Werkstücke nicht beschleunigt werden bedarf es keiner Abbremsung der Werkstücke, da die Werkstücke gleichmässig von der Transportbahn über die Transport- und Führungseinheit in den Auslagestern übergeben werden. Da keine Geschwindigkeitsänderungen erforderlich sind, d. h. keine Beschleunigung des Werkstücks und keine Abbremsung, können höhere Maschinengeschwindigkeiten gefahren werden, so dass der Materialdurchsatz dieser erfindungsgemässen Vorrichtung höher ist als bei vergleichbaren Vorrichtungen des Standes der Technik.Since the workpieces are not accelerated, no one is required Braking of the workpieces, since the workpieces evenly from the transport path via the transport and guidance unit in be handed over to the delivery star. Because no speed changes are required, d. H. no acceleration of the Workpiece and no braking, higher machine speeds be driven so that the material throughput this device according to the invention is higher than in comparable devices of the prior art.
Dabei wird die Transport- und Führungseinheit von einem unteren und einem oberen Transportband gebildet, wobei das Transportband von wenigstens zwei nebeneinander angeordneten O-Ringen gebildet wird. Dies hat den wesentlichen Vorteil, dass die Transportkräfte flächig auf das Werkstück übertragen werden können und somit die Transportbänder nur mit geringer Kraft an den Werkstücken anliegen müssen. Aufgrund der Unterteilung des Transportbandes in Transportstreifen oder O-Ringe kann mit dem Transportband problemlos zwischen die Aufnahmen des Auslagesterns, die insbesondere von Aufnahmefingern gebildet werden, eingefahren werden. Auf diese Weise ist die Übergabe des Werkstücks von den Transportbändern zum Auslagestern problemlos möglich.The transport and management unit is one formed lower and an upper conveyor belt, the Conveyor belt of at least two arranged side by side O-rings is formed. This has the main advantage that the transport forces are transferred across the workpiece can be and thus the conveyor belts with less Force must be applied to the workpieces. Because of the subdivision of the conveyor belt in transport strips or O-rings can be easily between the shots with the conveyor belt of the display star, especially from pick-up fingers be formed, retracted. That way it is Transfer of the workpiece from the conveyor belts to Delivery stars possible without any problems.
Bei einer Variante der Erfindung ist vorgesehen, dass der Auslagestern und das obere und das untere Transportband separate Antriebe aufweisen. Um Unterschiede in der Transportgeschwindigkeit zwischen dem oberen und dem unteren Transportband zu vermeiden weisen bei einer anderen Ausführungsform diese Bauteile einen gemeinsamen Antrieb auf. Ausserdem ist vorgesehen, dass der Auslagestern und die Transport- und Führungseinheit einen gemeinsamen Antrieb aufweisen, so dass gewährleistet ist, dass bei der Übergabe des Werkstücks von den Transportbändern zum Auslagestern das Werkstück nicht beschleunigt oder abgebremst wird. Insbesondere wird der gemeinsame Antrieb von einem Antriebsriemen gebildet, der um die Antriebselemente der Transport- und Führungseinheit bzw. des Auslagesterns gelegt ist.In a variant of the invention it is provided that the delivery star and the upper and lower conveyor belts separate Have drives. To differences in transport speed between the upper and lower conveyor belts Avoid pointing these components in another embodiment a common drive. It also provides that the delivery star and the transport and management unit have a common drive so that ensures is that when the workpiece is handed over by the Conveyor belts for delivery star the workpiece is not accelerated or braked. In particular, the common drive from one Drive belt formed around the drive elements of the Transport and management unit or delivery star is laid.
Bei einem Ausführungsbeispiel ist vorgesehen, dass der Auslagestern von der Transport- und Führungseinheit angetrieben wird. Dies hat den wesentlichen Vorteil, dass bei Schwankungen der Transportgeschwindigkeit diese von der Transport- und Führungseinheit an den Auslagestern weitergegeben werden und dadurch der relative Gleichlauf beibehalten wird.In one embodiment, it is provided that the Delivery star from the transport and guidance unit is driven. This has the main advantage that in the event of fluctuations in the transport speed, this depends on the Transport and guidance unit at the delivery star are passed on and thus the relative synchronism is maintained.
Mit Vorzug ist am Ausgang des Auslagesterns, an welchem die Werkstücke eine im Wesentlichen vertikale Position einnehmen, eine Aufnahme vorgesehen, in welche die Werkstücke hintereinander stehend abgelegt werden. Diese Aufnahme weist ein geschlitztes Ende auf, in welche Schlitze der Auslagestern mit seinen Transportfingern eingreift, wobei das Ende der Aufnahme die Werkstücke aus dem Auslagestern aushebt. Diese Übergabe der Werkstücke in die Aufnahme ist an sich bekannt, jedoch gestaltet sich das Lösen der Werkstücke aus dem Auslagestern wesentlich einfacher, da die Werkstücke von der Transport- und Führungseinheit mit geringerer Kraft in den Auslagestern eingeschoben worden sind, und deshalb weniger fest in diesem verankert sind.Preferably at the exit of the display star, at which the Workpieces in a substantially vertical position take a recording provided, in which the Workpieces are stored one after the other. This Recording has a slotted end in which Slots of the delivery star with its transport fingers engages, the end of the receptacle taking off the workpieces the delivery star. This handover of the workpieces in the recording is known per se, but it does Loosen the workpieces from the display star significantly easier because the workpieces from the transport and Guide unit with less force in the delivery star have been inserted, and therefore less firmly in are anchored to this.

Diese rohrähnliche Sammelvorrichtung wird bei einem bevorzugten Ausführungsbeispiel von mehreren zueinander parallelen Stangen gebildet, zwischen denen die Werkstücke ggf. mit geringer Reibung geführt werden. Die Reibung kann so eingestellt werden, dass die Werkstücke in vertikaler Ausrichtung gehalten werden, jedoch ein Transport in Längsrichtung der Sammelvorrichtung nicht behindert wird. Die Stangen liegen lediglich punktförmig an den Rändern der Werkstücke an, so dass die Reibungskräfte minimal sind. Die Verwendung von Stangen hat außerdem den Vorteil, dass der Querschnitt der Sammelvorrichtung optimal an unterschiedliche Querschnittsformen der Werkstücke angepasst werden kann. Auf diese Weise sind runde, ovale, rechteckförmige usw. ausgestaltete Werkstücke sammel- und transportierbar.Preferably, a pipe or pipe follows the receptacle tube-like collecting device. This tube-like Collecting device is preferred Embodiment of several parallel to each other Rods formed, between which the workpieces, if necessary low friction. The friction can be like this that the workpieces are set in vertical Alignment can be kept, however a transport in Longitudinal direction of the collecting device is not hindered.
