Description
Die Erfindung betrifft ein pneumatisch betätigtes Umreifungsgerät zum Umreifen eines Packstückes mit einem darumgelegten Kunststoffband, mit einer motorisch angetriebenen Spannvorrichtung und einer motorisch angetriebenen Schweißvorrichtung für das Kunststoffband, gemäß dem Obergriff des beigefügten Hauptanspruches.The invention relates to a pneumatically operated strapping device for strapping a package with a plastic band wound around it, with a motor-driven clamping device and a motor-driven welding device for the plastic band, according to the preamble of the accompanying main claim.
Geräte dieser Art sind bekannt z.B. aus der
Nachdem das Kunststoffband dann stramm um das Packstück gewickelt ist, wird es in diesem Zustand an der Stelle, wo es durch die Schweißvorrichtung läuft, zusammengedrückt. Dort wird dann eine Vibrationsplatte als Teil der Schweißvorrichtung auf die miteinander verklemmten Bänder abgesenkt und in Vibration versetzt. Die Vibration wird durch einen Motor über ein Getriebe erzeugt. Aufgrund dieser Vibration kommt es zwischen Ober- und Unterband zu einer Relativbewegung, die wegen der dabei entstehenden Friktion zu einem lokalen Aufschmelzen des thermoverschweißbaren Kunststoffbandes führt. Nach Beendigung der Vibrationsbewegung und einem kurzen Zeitraum des Abkühlens sind dann an der Verbindungsstelle Oberband und Unterband miteinander verschweißt.After the plastic tape is then tightly wrapped around the package, it is compressed in this condition at the point where it passes through the welding apparatus. There, a vibrating plate is then lowered as part of the welding device on the clamped bands and put into vibration. The vibration is generated by an engine via a gearbox. Due to this vibration occurs between upper and lower belt to a relative movement, which due to the resulting friction to a local melting of the thermoweldable Plastic band leads. After completion of the vibration movement and a short period of cooling then the upper and lower band are welded together at the junction.
Während des Vibrierens bzw. des Schweißvorganges wird üblicherweise das Oberband neben der Verbindungsstelle abgeschnitten. Abschließend kann das Umreifungsgerät dann von dem mit dem Kunststoffband umwickelten Packstück entfernt werden.During the vibration or the welding process usually the upper band is cut off next to the connection point. Finally, the strapping device can then be removed from the wrapped with the plastic strap package.
Da Umreifungsgeräte an unterschiedlichsten Stellen und aufgrund unterschiedlicher Packstücke auch in unterschiedlichsten Stellungen zum Einsatz kommen, werden sie oft manuell gehändelt und zum Beispiel zu ihren unterschiedlichsten Einsatzorten bewegt. Unter diesem Aspekt ist es wichtig, dass das Gerät für einen Bediener möglichst geringe körperliche Belastungen bewirkt.Since strapping tools are used at various points and due to different packages in a variety of positions, they are often manually handled and moved, for example, to their various locations. From this point of view it is important that the device causes the least possible physical strain for an operator.
Eine Aufgabe der vorliegenden Erfindung ist es daher, ein Umreifungsgerät der genannten Art möglichst leicht zu gestalten.An object of the present invention is therefore to make a strapping device of the type mentioned as easy as possible.
Hierzu ist es bekannt, dass die Spannvorrichtung und die Schweißvorrichtung, die an dem Umreifungsgerät vorgesehen sind, durch ein und denselben Pneumatikmotor angetrieben sind.For this purpose, it is known that the tensioning device and the welding device, which are provided on the strapping device, are driven by one and the same pneumatic motor.
Dies hat den Vorteil, dass nur ein Motor eingesetzt wird, obwohl mehrere motorisch anzutreibende Baugruppen in dem Umreifungsgerät vorhanden sind. Es können also motorische Antriebe eingespart werden, was sowohl einen Gewichtsvorteil bedeutet. Außerdem könne durch die Einsparung von teuren Pneumatikmotoren auch Kostenvorteile erzielt werden.This has the advantage that only one motor is used, although several motor-driven assemblies are present in the strapping device. So motor drives can be saved, which means both a weight advantage. In addition, cost savings could be achieved by saving on expensive pneumatic motors.
Wie bekannt erfolgt die alternative Verbindung des Pneumatikmotors mit der Spannvorrichtung oder mit der Schweißvorrichtung durch eine Umkehr seiner Laufrichtung.As is known, the alternative connection of the pneumatic motor with the clamping device or with the welding device by reversing its direction.
Um den Pneumatikmotor in entgegengesetzte Richtungen laufen zu lassen, hat er insbesondere zwei alternativ mit Druckluft zu beaufschlagende Zuluftkanäle.In order to run the pneumatic motor in opposite directions, he has in particular two alternatively to be acted upon with compressed air supply air ducts.
Diese Druckluft wird nach ihrer Entspannung im Rotor des Pneumatikmotors, die zu dessen Rotation führt, in bekannter Weise durch den Zentralauslass in die Umgebung abgeführt.This compressed air is discharged after its relaxation in the rotor of the pneumatic motor, which leads to its rotation, in a known manner through the central outlet into the environment.
Es ist dabei üblich, auch die Leerluft des Druckluftmotors über diesen Zentralauslass zu führen. Unter Leerluft wird dabei im Rahmen der vorliegenden Anmeldung die Luft verstanden, die bei Rotation des umsteuerbaren Pneumatikmotors in den Zellen des Rotors komprimiert wird, die bei der Rotation in Gegenrichtung zur Expansion der Druckluft genutzt werden. Diese Leerluft wird dem Zentralauslass dabei normalerweise über entsprechende Kanäle und Ventile, die diese Kanäle freischalten, zugeleitet.It is customary to also lead the empty air of the compressed air motor via this central outlet. In the context of the present application, empty air is understood to mean the air that is compressed in the cells of the rotor during rotation of the reversible pneumatic motor, which air is used during the rotation in the opposite direction to the expansion of the compressed air. This empty air is the central outlet thereby normally via corresponding channels and valves that enable these channels, fed.
Da diese Kanäle und Ventile für die Leerluft aber Widerstände darstellen, muss für das Ausschieben der Leerluft ein Teil der vom Pneumatikmotor gelieferten Leistung benutzt werden. Der Motor muss also zur Bereitstellung dieser Leistung entsprechend größer ausgeführt werden und ist damit wiederum relativ schwerer.However, since these channels and valves for the empty air represent resistances, a part of the power supplied by the pneumatic motor must be used for pushing out the empty air. The engine must therefore be made correspondingly larger to provide this power and is therefore in turn relatively heavier.
Um diesen Nachteil zu umgehen wird deswegen gemäß der Erfindung vorgesehen, dass in die alternativ mit Druckluft zu beaufschlagenden Zuluftkanäle für den umschaltbaren Pneumatikmotor jeweils bei einer entgegengesetzten Strömung selbsttätig nach außen entlüftende Umschaltventile integriert sind.In order to avoid this disadvantage, it is therefore provided according to the invention that in the air supply channels for the switchable pneumatic motor, which are alternatively to be pressurized, are automatically integrated in the case of an opposite flow to vent externally switching valves.
Diese Ventile sind dabei ziemlich nahe an dem Rotor des Pneumatikmotors integriert vorzusehen, insbesondere als in Strömungsrichtung der zuströmenden Druckluft letztes Bauelement vor dem Rotor. Bei einer Umschaltung des Pneumatikmotors in die andere Rotationsrichtung fungiert der soeben noch für die Zuluft benutzte Kanal als Abluftkanal. Durch diesen strömt dann die Leerluft des Motors und erreicht als erstes das Umschaltventil. Bis zu diesem Umschaltventil muss also von der Leerluft nur eine kurze Kanallänge überwunden werden, was einen Reibungsverlust und damit den Leistungsbedarf für das Ausschieben der Leerluft erheblich verringert.These valves are to be provided integrated fairly close to the rotor of the pneumatic motor, in particular as in the flow direction of the incoming compressed air last component in front of the rotor. When switching the pneumatic motor in the other direction of rotation of the just used for the supply air channel acts as an exhaust duct. Through this flows then the empty air of the engine and reaches the first the changeover valve. Up to this switching valve so only a short channel length must be overcome by the empty air, which significantly reduces a friction loss and thus the power requirement for the expulsion of the empty air.
Damit kann ein entsprechender Pneumatikmotor also mit weniger Leistung und damit auch kleiner ausgeführt werden und das Gewicht eines entsprechenden pneumatischen Umreifungsgerätes wird demgemäß weiter verringert.Thus, a corresponding pneumatic motor can thus be designed with less power and thus smaller and the weight of a corresponding pneumatic strapping device is accordingly further reduced.
Bei einer besonders bevorzugten Ausführungsform ist in den Umschaltventilen eine im Querschnitt im Wesentlichen M-förmige Schaltmembran vorhanden, die je nach ihrer Anströmrichtung umschaltbar ist zwischen einer Freigabestellung für den Zuluftkanal und einer Freigabestellung für die Auslassöffnung des Umschaltventils zu der Umgebung.In a particularly preferred embodiment is in the changeover valves in cross-section substantially M-shaped switching membrane present, which is switchable depending on their direction of flow between a release position for the supply air duct and a release position for the outlet opening of the changeover valve to the environment.
Bei einer besonders bevorzugten Ausführungsform der Erfindung ist der in seiner Antriebsrichtung umsteuerbare Pneumatikmotor über in entgegengesetzte Richtungen freigebende Freiläufe alternativ mit der Spann- oder der Schweißvorrichtung in Wirkverbindung gebracht.In a particularly preferred embodiment of the invention, the reversible in its drive direction pneumatic motor is brought into opposite directions releasing freewheels with the tensioning or welding device in operative connection.
Eine Konstruktion in dieser Weise hat den Vorteil, dass sie sehr betriebssicher ist. Mit ihr ist sichergestellt, dass entweder die Spann- oder aber die Schweißvorrichtung angetrieben sind, nicht aber beide Vorrichtungen gleichzeitig. Dabei kann dieser alternative Antrieb ohne aufwändige Steuerung realisiert werden, die sowohl Gewichts- als auch Kostennachteile hätte.A construction in this way has the advantage that it is very reliable. With her it is ensured that either the clamping or the welding device are driven, but not both devices simultaneously. This alternative drive can be realized without complex control, which would have both weight and cost disadvantages.
Konstruktiv wird vorgeschlagen, dass der Pneumatikmotor eine an seinen beiden Enden herausragende Motorwelle aufweist, die an ihren aus dem Motor herausragenden Enden jeweils mit einer der in entgegengesetzte Richtungen freigebenden Freiläufen verbunden ist.It is proposed by design that the pneumatic motor has a motor shaft projecting at both its ends, which is connected at each of its ends projecting from the motor to one of the freewheels which open in opposite directions.
Durch diese Konstruktionen ist zu erreichen, dass die Motorwelle nur über kurze Strecken Torsionsmomente übertragen muss. Sie kann somit kleiner dimensioniert werden und ist somit auch leichter.As a result of these designs, the motor shaft only has to transmit torsional moments over short distances. It can thus be made smaller and is therefore also lighter.
Es wäre zwar auch möglich, die in entgegengesetzte Drehrichtungen freigebenden Freiläufe auf der gleichen Seite des Pneumatikmotors auf dessen Motorwelle zu montieren. Dann müssten bei Abnahme der Motorleistung über den weiter vom Pneumatikmotor beabstandeten Freilauf die Drehmomente aber über eine längere Strecke durch die Motorwelle geleitet werden. Da jede Welle mit einer gewissen Torsionselastizität versehen ist, könnten hierdurch eventuell bei der Umschaltung von der einen auf die andere Rotationsrichtung auch unerwünschte Effekte auftreten.Although it would also be possible to mount the freewheeling in opposite directions of rotation on the same side of the pneumatic motor on the motor shaft. Then, the torque would have to be passed through the motor shaft over a longer distance when the engine power decreases over the freewheel spaced further from the pneumatic motor. Since each shaft is provided with a certain torsional elasticity, this could possibly also result in the switching from one direction of rotation to the other undesirable effects.
Außerdem müsste die Welle dann stärker dimensioniert werden, was dem Ziel eines möglichst leichten Gerätes entgegenwirken würde.In addition, the shaft would then have to be dimensioned larger, which would counteract the goal of the lightest possible device.

Das Kunststoffband wird dann über ein motorisch angetriebenes Reibrad stramm gezogen, so dass es eng um das Packstück herumliegt. Abschließend wird das Kunststoffband dann an einer Position innerhalb des Umreifungsgerätes, an dem es sich nach Bildung der Schlaufe überlappt, zur Bildung einer Verbindungsstelle zusammengedrückt. An dieser Position wird dann eine Vibrationsplatte auf die miteinander verklemmten Bänder abgesenkt und diese Vibrationsplatte wird motorisch in Vibration versetzt. Aufgrund dieser Vibration kommt es an der Verbindungsstelle zwischen den beiden überlappenden Bandabschnitten zu einer Relativbewegung und wegen der dabei entstehenden Friktion zu einem lokalen Aufschmelzen des thermoverschweißbaren Kunststoffbandes.The plastic band is then pulled tightly over a motor-driven friction wheel, so that it lies tightly around the package. Finally, the plastic tape is then compressed at a position within the strapping device, where it overlaps after formation of the loop, to form a joint. At this position, a vibrating plate is then lowered onto the clamped bands and this vibrating plate is vibrated by a motor. Due to this vibration, a relative movement occurs at the connection point between the two overlapping strip sections and, due to the resulting friction, a local melting of the thermo-weldable plastic strip.
Abschließend kann diese verschweißte Verbindungstelle dann noch abkühlen, so dass eine feste Schweißstelle gebildet ist und das Umreifungsgerät kann von dem Packband entfernt werden, wobei das Packband aus dem Schlitz 6 herausgleitet.Finally, this welded connection point can then cool, so that a firm weld is formed and the strapping device can be removed from the packaging tape, wherein the packing belt slides out of the slot 6.
