Description
Die Erfindung betrifft eine Verpackungsmaschine mit zwei Quersiegelbacken zum Versiegeln einer Verpackung.The invention relates to a packaging machine with two transverse sealing jaws for sealing a package.
Aus der Praxis sind Verpackungsmaschinen mit zwei Quersiegelbacken zum Versiegeln einer Verpackung bekannt, bei der die Quersiegelbacken in eine Siegelposition gebracht werden und die Verpackung in Form eines Verpackungsschlauches versiegelt, das heißt verschließt.In practice, packaging machines with two transverse sealing jaws for sealing a package are known, in which the transverse sealing jaws are brought into a sealing position and the package is sealed in the form of a packaging tube, that is, closes.
Bei diesen aus der Praxis bekannten Verpackungsmaschinen besteht der Nachteil, dass die Quersiegelbacken immer in die Siegelposition gefahren werden, unabhängig davon, ob zu verpackendes Gut und andere Gegenstände sich im Bereich der Quersiegelbacken befinden.In these packaging machines known from practice there is the disadvantage that the transverse sealing jaws are always moved to the sealing position, regardless of whether goods to be packaged and other objects are located in the region of the transverse sealing jaws.
Insbesondere wenn empfindliche Güter, wie beispielsweise Kleinteile bei Spielzeugen oder Lebensmittel, wie zum Beispiel Gummibärchen verpackt werden, ist es nachteilig, wenn die Quersiegelbacken in die Siegelposition fahren und den Verpackungsschlauch versiegeln, obwohl sich Kleinteile oder Lebensmittel im Bereich der Quersiegelbacken befinden. Die Kleinteile werden durch das Siegeln zerstört. Lebensmittel werden durch den Siegelvorgang geschmolzen und die Maschine muss aufwändig gereinigt werden.In particular, when sensitive goods, such as small parts are packaged in toys or food, such as gummy bears, it is disadvantageous when the cross-sealing jaws go to the sealing position and seal the packaging tube, although small parts or food in the transverse sealing jaws. The small parts are destroyed by the sealing. Food is melted by the sealing process and the machine must be cleaned consuming.

Das der Erfindung zugrunde liegende technische Problem besteht darin, eine Verpackungsmaschine anzugeben, mit der die genannten Nachteile nicht auftreten.The technical problem underlying the invention is to provide a packaging machine with which the disadvantages mentioned do not occur.
Dieses technische Problem wird durch eine Verpackungsmaschine mit den Merkmalen gemäß Anspruch 1 gelöst.This technical problem is solved by a packaging machine with the features according to claim 1.
Die erfindungsgemäße Verpackungsmaschine weist zwei Quersiegelbacken zum Versiegeln einer Verpackung auf, bei der eine erste Quersiegelbacke mit einer einstellbaren und/oder vorgegebenen, von wenigstens einer ersten Krafterzeugungseinrichtung erzeugten Kraft ausweichbar gegenüber einer zweiten Quersiegelbacke gelagert ist, wobei ein Ausweichen der ersten Quersiegelbacke von einem Sensor erfassbar ist und zur Erzeugung eines für das Siegeln erforderlichen Druckes wenigstens eine zweite Krafterzeugungseinrichtung vorgesehen ist, die in Parallelschaltung zur ersten Krafterzeugungseinrichtung auf die erste Quersiegelbacke wirkend ausgebildet ist, und bei der die von der ersten Krafterzeugungseinrichtung erzeugte Kraft kleiner ist als die von der zweiten Krafterzeugungseinrichtung.The packaging machine according to the invention has two transverse sealing jaws for sealing a packaging, in which a first transverse sealing jaw with an adjustable and / or predetermined force generated by at least one first force generating device is mounted deflectable relative to a second transverse sealing jaw, wherein a deflection of the first transverse sealing jaw can be detected by a sensor is and for generating a pressure required for sealing at least a second force generating device is provided which is formed in parallel to the first force generating device acting on the first transverse sealing jaw, and in which the first Force generating device generated force is smaller than that of the second force generating device.
Durch die erfindungsgemäße Ausführungsform der Verpackungsmaschine weicht die ausweichbar gelagerte Quersiegelbacke aus, wenn sich ein Hindernis im Bereich der Quersiegelbacken befindet. Dadurch, dass die von der ersten Krafterzeugungseinrichtung erzeugte Kraft kleiner ist als die von der zweiten Krafterzeugungseinrichtung, können mit der erfindungsgemäßen Verpackungsmaschine empfindliche Güter verpackt werden.As a result of the embodiment of the packaging machine according to the invention, the deflectably mounted jaw deviates when an obstacle is located in the region of the transverse sealing jaws. Characterized in that the force generated by the first force generating means is smaller than that of the second force generating device, can be packed with the packaging machine according to the invention sensitive goods.
Durch die erste Krafterzeugungseinrichtung wird eine wesentlich kleinere Kraft erzeugt als durch die zweite Krafterzeugungseinrichtung. Das bedeutet, dass die Quersiegelbacken mittels der ersten Krafterzeugungseinrichtung mit einem relativ geringen Druck zusammengefahren werden. Durch diesen geringen Druck werden empfindliche Güter nicht zerstört, sofern sie sich noch in dem Bereich zwischen den Quersiegelbacken befinden. Werden keine empfindlichen Güter in dem Bereich detektiert, wird mit der zweiten Krafterzeugungseinrichtung der für das Siegeln erforderliche Druck erzeugt und der Siegelvorgang wird durchgeführt.By the first force generating device, a much smaller force is generated than by the second force generating device. This means that the transverse sealing jaws are moved together by means of the first force generating device with a relatively low pressure. Due to this low pressure sensitive goods are not destroyed, if they are still in the area between the transverse sealing jaws. If no sensitive goods are detected in the area, the second force generating means generates the pressure required for the sealing, and the sealing operation is performed.
Die von der ersten Krafterzeugungseinrichtung erzeugte Kraft ist so gering, dass Güter, die sich zwischen den Siegelbacken befinden, zerstörungsfrei detektiert werden. Die wenigstens eine Siegelbacke weicht beim Zusammenfahren gegen die Kraft der ersten Krafterzeugungseinrichtung dem Hindernis aus. Die zweite Krafterzeugungseinrichtung erzeugt eine für den Siegelvorgang erforderliche Kraft. Diese ist deutlich größer als die von der ersten Krafterzeugungseinrichtung erzeugte Kraft.The force generated by the first force generating device is so low that goods located between the sealing jaws are detected non-destructively. The at least one sealing jaw deviates from the obstacle when moving against the force of the first force generating device. The second force generating device generates a force required for the sealing process. This is significantly greater than the force generated by the first force generating device.
Gemäß einer besonders bevorzugten Ausführungsform der Erfindung ist die ausweichbar gelagerte Quersiegelbacke an einer Trägerleiste angeordnet. Gemäß einer weiteren vorteilhaften Ausführungsform ist die Trägerleiste verfahrbar in der Verpackungsmaschine gelagert.According to a particularly preferred embodiment of the invention, the deflectably mounted cross-sealing jaw is arranged on a carrier strip. According to a further advantageous embodiment, the carrier strip is movably mounted in the packaging machine.
Durch die Anordnung der Quersiegelbacke an der Trägerleiste ist es möglich, die Quersiegelbacke ausweichbar zu lagern, beispielsweise mittels wenigstens einer Feder an der Trägerleiste oder mittels eines pneumatischen Kolbens oder mittels wenigstens eines elektrischen Kolbens.By arranging the transverse sealing jaw on the carrier strip, it is possible to mount the transverse sealing jaw in an evasive manner, for example by means of at least one spring on the carrier strip or by means of a pneumatic piston or by means of at least one electric piston.
Die zweite Krafterzeugungseinrichtung, die die für den Siegelvorgang erforderliche Kraft erzeugt, wirkt erst, wenn aufgrund der ersten Krafterzeugungseinrichtung die Siegelbacken ordnungsgemäß geschlossen sind und kein Hindernis dadurch detektiert wird, dass die ausweichbar gelagerte Siegelplatte aufgrund eines Hindernisses ausweicht.The second force generating device, which generates the force required for the sealing process, acts only when due to the first force generating device, the sealing jaws are properly closed and no obstacle is detected by the evasive mounted seal plate evades due to an obstacle.
Gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung ist wenigstens ein Sensor zur Erfassung der ordnungsgemäßen Siegelstellung der beiden Quersiegelbacken vorgesehen.According to a further advantageous embodiment of the invention, at least one sensor for detecting the proper sealing position of the two transverse sealing jaws is provided.
Können die Quersiegelbacken aufgrund eines Hindernisses nicht ordnungsgemäß schließen, so weicht die ausweichbar gelagerte Quersiegelbacke aus. Dieses Ausweichen wird von einem Sensor erfasst, und es besteht die Möglichkeit, die Quersiegelbacke umgehend zu öffnen, bevor der Siegelvorgang durchgeführt wird.If the cross-sealing jaws can not close properly due to an obstacle, the deflectable jaw that deflects away evades. This deflection is detected by a sensor and it is possible to immediately open the cross-sealing jaw before the sealing process is performed.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist es möglich, entweder die vordere oder die hintere Quersiegelbacke als ausweichbar gelagerte Quersiegelbacke auszubilden. Je nach Ausführungsform der Verpackungsmaschine kann die eine oder andere Variante bevorzugt werden.According to a further advantageous embodiment of the invention, it is possible to form either the front or the rear transverse sealing jaw as evasive mounted transverse sealing jaw. Depending on the embodiment of the packaging machine, one or the other variant may be preferred.
Die erfindungsgemäße Verpackungsmaschine weist vorteilhaft einen Antrieb für die erste und/oder zweite Quersiegelbacke auf, der die beiden Quersiegelbacken in eine Siegelposition und aus der Siegelposition herausbringt, und zwar vorteilhaft über zwei Kniehebel.The packaging machine according to the invention advantageously has a drive for the first and / or second transverse sealing jaw, which brings out the two transverse sealing jaws in a sealing position and from the sealing position, advantageously via two toggle levers.
Die Kniehebel werden vorteilhaft von einem Motor angetrieben. Die Siegelposition der beiden Quersiegelbacken wird vorteilhaft dann erreicht, wenn Längsachsen der beiden Kniehebel fluchten.The toggle levers are advantageously driven by a motor. The sealing position of the two transverse sealing jaws is advantageously achieved when longitudinal axes of the two knee levers are aligned.
Durch die Ausbildung des Antriebes über Kniehebel wird eine besonders günstige Kraftverteilung erzielt und durch die fluchtenden Längsachsen der beiden Kniehebel in der Siegelposition ist die genaue Siegelposition festgelegt.Due to the design of the drive via toggle a particularly favorable force distribution is achieved and by the aligned longitudinal axes of the two toggle lever in the sealing position, the exact sealing position is fixed.
Das Fluchten der Längsachsen der beiden Kniehebel wird vorteilhaft mittels wenigstens eines Sensors überwacht, um den Siegelvorgang auszulösen.The alignment of the longitudinal axes of the two toggle levers is advantageously monitored by means of at least one sensor in order to trigger the sealing process.
Gemäß einer besonders bevorzugten Ausführungsform der Erfindung ist für die Bewegung der Quersiegelbacken wenigstens eine Zug- und Schubstange, vorzugsweise zwei Zug- und Schubstangen vorgesehen und an der wenigstens einen Zug- und Schubstange ist eine Quersiegelbacke befestigt, so dass diese bei Bewegung der Zug- und Schubstange mit der Zug- und Schubstange hin- und herbewegt wird und die Trägerleiste mit der ausweichbar gelagerten Quersiegelbacke ist beweglich auf der wenigstens einen Zug- und Schubstange gelagert.According to a particularly preferred embodiment of the invention, at least one pull and push rod, preferably two pull and push rods is provided for the movement of the transverse sealing jaws and on the at least one pull and push rod a transverse sealing jaw is attached so that they move the train and Push rod is moved back and forth with the pull and push rod and the support bar with the deflectable mounted cross-sealing jaw is movably mounted on the at least one pull and push rod.
Es besteht auch die Möglichkeit gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung, das System umzukehren und die Trägerleiste mit der ausweichbar gelagerten Quersiegelbacke an der Zug- und Schubstange zu befestigen und dann die andere Quersiegelbacke beweglich auf der Zug- und Schubstange zu lagern.There is also the possibility according to a further advantageous embodiment of the invention to reverse the system and the carrier strip with the evasive mounted cross-sealing jaw to attach the pull and push rod and then to store the other cross-sealing jaw movable on the pull and push rod.
Vorteilhaft wird die beweglich gelagerte Quersiegelbacke oder Trägerleiste über einen Kniehebel von einem Motor angetrieben. Über den anderen Kniehebel wird vorteilhaft die Zug- und Schubstange in Bewegung versetzt. Die Kniehebel sind derart angeordnet, dass die auf der Zug- und Schubstange beweglich gelagerte Quersiegelbacke oder Trägerleiste eine gegenläufige Bewegung zu der an der Zug- und Schubstange fest angeordneten Quersiegelbacke oder Trägerleiste ausführt, so dass bei fluchtenden Längsachsen der Kniehebel, also wenn die Kniehebel in einer Geradstellung angeordnet sind, die Siegelbacken in einer Siegelposition nahe beieinander angeordnet sind.Advantageously, the movably mounted transverse sealing jaw or carrier strip is driven by a motor via a toggle lever. About the other toggle is advantageously the pull and push rod in motion. The toggle levers are arranged such that the movably mounted on the pull and push rod transverse sealing jaw or support bar performs an opposite movement to the fixed to the pull and push rod transverse sealing jaw or support bar, so that when aligned longitudinal axes of the toggle, so if the toggle in a straight position are arranged, the sealing jaws are arranged in a sealed position close to each other.
Diese Ausführungsform hat den Vorteil, dass an der Zug- und Schubstange lediglich die eine Quersiegelbacke oder die Trägerleiste mit einer Quersiegelbacke fest angeordnet ist und die Zug- und Schubstange mit der fest daran angeordneten Quersiegelbacke und/oder Trägerleiste ein relativ geringes Gewicht aufweist und dass die andere beweglich an der Zug- und Schubstange gelagerte Quersiegelbacke oder Trägerleiste die Zug- und Schubstange ausschließlich zur Führung benötigt und unmittelbar von dem Motor über einen Kniehebel angetrieben wird. Hierdurch hat der Motor immer nur relativ geringe Massen anzutreiben, was vorteilhaft ist.This embodiment has the advantage that only a transverse sealing jaw or the carrier strip with a transverse sealing jaw is fixedly arranged on the pull and push rod and the pull and push rod with the transverse sealing jaw and / or carrier strip arranged thereon has a relatively low weight and that the Other movable mounted on the pull and push rod transverse sealing jaw or support bar the pull and push rod needed only for leadership and is driven directly by the engine via a toggle. As a result, the engine has only relatively low masses to drive, which is advantageous.
Vorteilhaft kann beispielsweise an wenigstens einem Kniehebel wenigstens ein Nocken angeordnet sein. Über diesen Nocken wird der wenigstens eine Sensor angesprochen, so dass der Sensor signalisieren kann, dass die Siegelstellung erreicht ist und der Siegelvorgang durchgeführt werden kann.Advantageously, for example, at least one cam can be arranged on at least one toggle lever. About this cam, the at least one sensor is addressed, so that the sensor can signal that the sealing position is reached and the sealing process can be performed.
Wird die ausweichbar gelagerte Quersiegelbacke gegen die zweite Quersiegelbacke verfahren, steht die ausweichbar gelagerte Quersiegelbacke lediglich unter dem Druck der ersten Krafterzeugungseinrichtung, also beispielsweise unter Federdruck oder unter dem Druck des wenigstens einen pneumatischen oder elektrischen Kolbens. Kann die ausweichbar gelagerte Quersiegelbacke in die Siegelposition verfahren werden, ohne dass sie aufgrund eines Hindernisses ausweicht, wird nunmehr von der zweiten Krafterzeugungseinrichtung, beispielsweise von wenigstens einem Hochdruckzylinder der für das Siegeln erforderliche Druck erzeugt, so dass die Quersiegelbacken beim eigentlichen Siegelvorgang mit einem höheren Druck als dem vorgegebenen oder voreingestellten Druck zusammengepresst werden.If the deflectably mounted cross-sealing jaw is moved against the second transverse sealing jaw, the deflectably mounted jaw is only under the pressure of the first force-generating device, thus for example under spring pressure or under the pressure of the at least one pneumatic or electric piston. If the deflectably mounted cross-sealing jaw can be moved into the sealing position without it escaping due to an obstacle, the pressure required for sealing is now generated by the second force-generating device, for example by at least one high-pressure cylinder, so that the transverse sealing jaws are subjected to a higher pressure during the actual sealing process be compressed as the predetermined or preset pressure.
