Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Transport eines Trägermaterialstrangs, welcher wenigstens einseitig mit einzelnen, voneinander beabstandeten und nacheinander folgenden, allseitig geschlossenen, jeweils ein Substanzquantum enthaltenden Kammern verbunden ist und aus bahnförmigem Trägermaterial besteht.The present invention relates to a device for transporting a Base material strand, which is at least one-sided with individual, from each other spaced and consecutive, closed on all sides, one each Chambers containing substance quantum is connected and made of web-shaped Carrier material consists.

Ein derartig mit Kammern versehener Trägermaterialstrang ist insbesondere bei der kontinuierlichen Herstellung von Aufgußbeuteln zur Bereitung von Tee zu transportieren. Derartige Aufgußbeutel bestehen aus mindestens einer ein Substanzquantum einer auszulaugenden Substanz enthaltenden, durch Quersiegelung eines Schlauches aus Filtermaterial entstandenen Kammer und einem mit der Kammer verbundenen Abschnitt einer Trägermaterialbahn, der zur Handhabung und Aufhängung des Aufgußbeutels dient.Such a strand of carrier material provided with chambers is in particular at the continuous production of infusion bags for the preparation of tea transport. Such infusion bags consist of at least one Quantum of substance of a substance to be leached, by Cross sealing of a hose made of filter material and chamber a section of a carrier material web connected to the chamber, which for Handling and suspension of the infusion bag is used.

Der Transport eines mit Kammern versehenen Trägermaterialstrangs als Zwischenprodukt, insbesondere im Rahmen einer kontinuierlichen Herstellung von Aufgußbeuteln zur Bereitung von Tee, ist mir herkömmlichen Zugeinrichtungen, beispielsweise Rollenzügen, aufgrund der am Trägermaterialstrang angeordneten und gefüllten Kammern aus Filterpapiermaterial nicht bzw. nur unbefriedigend bewerkstelligbar. Der Trägermaterialstrang ist nur an diskreten Stellen erfaßbar, da ansonsten die Kammern und/oder die in den Kammern vorhandenen Substanzquanten beschädigt werden. Ein weiteres Problem ist bei der kontinuierlichen Herstellung von Aufgußbeuteln in Fertigungstoleranzen gegeben. So weichen die Abstände der Kammern am Trägermaterialstrang aufgrund von Fertigungstoleranzen, die sich insbesondere im Rahmen einer kontinuierlichen Herstellung durch gegenseitige Beeinflussung vergrößern können, unterschiedlich stark voneinander ab. Derartige Fertigungstoleranzen sind beispielsweise bei mit Druckmarken versehenen Trägermaterialien in unterschiedlichen Abständen der Druckmarken zueinander aufgrund von Toleranzen der Bedruckung des Trägermaterials begründet. Ein sicherer und insbesondere beschädigungsfreier Transport des mit Kammern versehenen Trägermaterialstrangs ist insofern erschwert.The transport of a strand of carrier material provided with chambers as Intermediate, especially in the context of a continuous production of Infusion bags for the preparation of tea, is conventional pulling devices, For example, roller trains, due to the arranged on the strand of carrier material and filled chambers made of filter paper material not or only unsatisfactorily bewerkstelligbar. The strand of carrier material can only be detected at discrete locations, since otherwise the chambers and / or those present in the chambers Substance quanta are damaged. Another problem is with the given continuous production of infusion bags in manufacturing tolerances. For example, the distances between the chambers on the strand of carrier material differ due to Manufacturing tolerances, which are particularly in the context of a continuous Manufacturing can increase through mutual influence, different strongly different from each other. Such manufacturing tolerances are for example with Carrier materials provided with printing marks at different intervals Print marks to each other due to tolerances in the printing of the carrier material founded. Safe and damage-free transport in particular the strand of carrier material provided with chambers is thus difficult.

Der Erfindung liegt in Anbetracht dieses Standes der Technik die Aufgabe zugrunde, eine Vorrichtung zum Transport eines mit Kammern versehenen Trägermaterialstrangs der eingangs genannten Art bereitzustellen, welche ein beschädigungsfreies und zuverlässiges Transportieren eines mit Kammern versehenen Trägermaterialstrangs mit hoher Geschwindigkeit ermöglicht.In view of this prior art, the invention is based on the object of providing a device for transporting a strand of carrier material provided with chambers of the type mentioned at the outset, which enables damage-free and reliable transport of a strand of carrier material provided with chambers at high speed.

Zur technischen Lösung wird mit der vorliegenden Erfindung eine Vorrichtung der eingangs genannten Art bereitgestellt, mit wenigstens zwei unabhängig voneinander angetriebenen Riemen, deren Trum jeweils wenigstens teilweise parallel zum Trägermaterialstrang verläuft und die auf der dem Trägermaterialstrang zugewandten Seite voneinander beabstandet angeordnete Nocken aufweisen, die den Trägermaterialstrang zwischen den Kammern und/oder im Bereich der Verbindung einer Kammer mit dem Trägermaterialstrang durch Zusammenwirken mit einem auf der gegenüberliegenden Seite des Trägermaterialstrangs angeordneten Gegenlager erfassen und mit der Bewegung der Riemen transportieren.For the technical solution , the present invention provides a device of the type mentioned at the outset, with at least two independently driven belts, the strands of which each run at least partially parallel to the strand of support material and which have spaced-apart cams on the side of the support material strand which have the support material strand between the chambers and / or in the area of the connection of a chamber to the strand of carrier material by interaction with a counterbearing arranged on the opposite side of the carrier material strand and transport it with the movement of the belt.

Erfindungsgemäß wird der Trägermaterialstrang an diskreten Stellen erfaßt und in Transportrichtung gezogen. Die erfindungsgemäße Vorrichtung hat den Vorteil, daß ein zuverlässiger und schneller Transport des mit Kammern versehenen Trägermaterialstrangs gegeben ist, wobei durch ein Erfassen der Nocken zwischen den Kammern und/oder im Bereich der Verbindung einer Kammer mit dem Trägermaterialstrang sichergestellt ist, daß die Kammer nicht beschädigt werden. Die erfindungsgemäße Vorrichtung erlaubt so einen Transport mit hoher Produktionsleistung. Die Verwendung von zwei unabhängig voneinander angetriebenen Riemen deren Trum wenigstens teilweise parallel zum Trägermaterialstrang verläuft und die auf der dem Trägermaterialstrang zugewandten Seite voneinander beabstandet angeordnete Nocken aufweisen, ermöglicht es darüber hinaus, aufgrund von Toleranzen, insbesondere Druckmarkentoleranzen, gegebene Abweichungen der Abstimmung der Teilung der Kammern am Trägermaterialstrang auszugleichen. Vorteilhaft sind dazu die Antriebe der Riemen derart steuerbar, daß die beiden Riemen den Trägermaterialstrang abwechselnd transportieren, wobei ein Nocken des einen Riemens in Eingriff mit dem Trägermaterialstrang ist und den Trägermaterialstrang transportiert, während ein Nocken des anderen Riemens in eine Position zum Erfassen des Trägermaterialstrangs gebracht wird und den Trägermaterialstrang anschließend transportiert. Damit ist ein absolut positionsgenauer Transport des Trägermaterialstrangs gegeben. Vorteilhafter Weise werden für die Antriebe der Riemen Servomotoren verwendet.According to the invention, the strand of carrier material is detected at discrete locations and in Direction of transport pulled. The device according to the invention has the advantage that a reliable and fast transport of the chambered strand of carrier material is given, by detecting the cams between the chambers and / or in the region of the connection of a chamber to the strand of carrier material it is ensured that the chamber is not damaged. The The device according to the invention thus permits transport with high production output. The use of two independently driven belts Run runs at least partially parallel to the strand of carrier material and on the side facing the strand of carrier material is arranged at a distance from one another Having cams also allows, due to tolerances, especially print mark tolerances, given deviations in the coordination to compensate for the division of the chambers on the strand of carrier material. Advantageous the drives of the belts can be controlled such that the two belts alternately transport the strand of carrier material, one cam of one Belt is engaged with the strand of substrate and the strand of substrate transported while one cam of the other belt in one position is brought to grasp the carrier material strand and the carrier material strand then transported. This makes transport absolutely precise given the strand of carrier material. Be advantageous for the drives the belt uses servo motors.

In einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die Antriebe druckmarkengesteuert, wobei die Druckmarken bevorzugt auf dem Trägermaterialstrang angeordnet sein können. Seitens der erfindungsgemäßen Transportvorrichtung sind dabei zur Steuerung der Antriebe optische Sensoren vorgesehen, die die auf dem Trägermaterialstrang angeordneten Druckmarken erkennen und die Riemen derart antreiben, daß die Nocken jeweils in eine Position zum Erfassen des Trägermaterialstrangs verbringbar sind.In a further advantageous embodiment of the invention, the drives are controlled by print marks, the print marks preferably on the carrier material strand can be arranged. On the part of the transport device according to the invention optical sensors are provided to control the drives recognize the printed marks arranged on the carrier material strand and the Drive the belt so that the cams are each in a gripping position of the strand of carrier material can be brought.

Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung sind die Riemen der Transportvorrichtung in Richtung des Transports des Trägermaterialstrangs nebeneinander angeordnet, wobei die wenigstens teilweise parallel zum Trägermaterialstrang verlaufenden Trums der Riemen sich in Transportrichtung des Trägermaterialstrangs wenigstens teilweise überlappen. Die Bereiche der Riemen liegen somit in Transportrichtung des Trägermaterialstrangs senkrecht zur Transportrichtung hintereinander.According to a further advantageous embodiment of the invention, the straps are the transport device in the direction of the transport of the carrier material strand arranged side by side, the at least partially parallel to the strand of carrier material running strands of the belts in the direction of transport of the carrier material strand at least partially overlap. The areas of the straps lie thus in the direction of transport of the strand of carrier material perpendicular to the direction of transport behind each other.

Gemäß einer weiteren besonders vorteilhaften Ausgestaltung der Erfindung weist diese beidseits des Trägermaterialstrangs zwei unabhängig voneinander angetriebene Riemen auf, die zumindest im Bereich der parallel zum Trägermaterialstrang verlaufenden Trums einander gegenüberstehen. Vorteilhaft sind die einander gegenüberstehenden Riemen von einem Antrieb angetrieben, wobei die Nocken der einander gegenüberstehenden Riemen zweckmäßig derart ausgerichtet sind, daß diese gegenseitig ein Gegenlager ausbilden, so daß die einander gegenüberstehenden Nocken der gegenüberliegenden Riemen praktisch Zangen zum Greifen des Trägermaterialstrangs ausbilden.According to a further particularly advantageous embodiment of the invention these two independently of each other on the strand of support material driven belt on, at least in the area parallel to the The strand of carrier material running opposite each other. Advantageous the opposing belts are driven by a drive, the cams of the opposing belts suitably such are aligned that they mutually form a counter bearing, so that the opposite cams of the opposite belts practical Use pliers to grip the strand of substrate.

Gemäß einem weiteren vorteilhaften Vorschlag sind die Nocken wenigstens einer Seite der Riemen federgelagert, so daß ein absolut sicheres Erfassen bei gleichzeitigem Ausschluß jeglicher Beschädigungen des Trägermaterialstrangs oder der Kammern gewährleistet ist. In einer konkreten Ausgestaltung der Erfindung verlaufen die Riemen jeweils über ein Antriebsrad, ein Abtriebsrad und ein Spannrad, welche in Form eines Dreiecks zueinander angeordnet sind, wobei der parallel zum Trägermaterialstrang verlaufende Trum zwischen Antriebsrad und Umlenkrad verläuft und gegenüber dem Spannrad liegt. Durch die dreieckförmige Anordnung des Antriebsrades, des Abtriebrades und des Spannrades der erfindungsgemäßen Transportvorrichtung läßt sich diese äußerst kompakt ausbilden. In einer vorteilhaften Ausgestaltung der Erfindung sind die Nocken derart örtlich verteilt auf den Riemen angeordnet, daß der Trägermaterialstrang im Bereich des Abstandes bzw. der Verbindung jeder zweiten Kammer, besonders bevorzugt jeder vierten Kammer erfaßbar ist.According to a further advantageous proposal, the cams are at least one Side of the straps spring-loaded, so that an absolutely secure grasp at simultaneous exclusion of any damage to the strand of carrier material or the chambers is guaranteed. In a concrete form of the Invention, the belts each have a drive wheel, a driven wheel and a tension wheel, which are arranged in the form of a triangle to each other, wherein the run between the drive wheel and Deflection wheel runs and lies opposite the tensioning wheel. Due to the triangular shape Arrangement of the drive wheel, the driven wheel and the tensioning wheel Transport device according to the invention, this can be extremely compact form. In an advantageous embodiment of the invention, the cams are so locally distributed on the belt that the substrate strand in Range of distance or connection of every second chamber, especially preferably every fourth chamber is detectable.

Die Antriebe 11, vorliegend Servomotoren, der Riemen 2, 2' bzw. 3, 3' sind über auf dem Trägermaterialstrang angebrachte Druckmarken gesteuert. Dabei werden wechselweise die Nocken einander gegenüberliegender Riemen 2, 2' bzw. 3, 3' in eine Position zum Erfassen des Trägermaterialstrangs 12 verbracht und der Trägermaterialstrang 12, wie in Figur 2, dargestellt von gegenüberstehenden Nocken gegriffen, während die Nocken des daneben liegenden Riemenpaares den Trägermaterialstrang 12 aufgrund noch im Eingriff befindlicher Nocken transportieren. Die einander gegenüberliegenden Riemen 2, 2' bzw. 3, 3' übernehmen so abwechselnd den Transport des Trägermaterialstrangs 12. Dabei transportieren abwechselnd die Nocken 4, 5 des einen Riemens 2, 2' bzw. 3, 3' den Trägermaterialstrang 12 während die Nocken 4, 5 des zweiten Riemens 3, 3' bzw. 2, 2' zur anschließenden Übernahme des Weitertransports in eine Transportposition verbracht werden. Der erste Riemen der Vorrichtung fährt druckmarkengesteuert über Servomotoren in Transportposition und transportiert den mit Kammern 6 versehenen Trägermaterialstrang 12 ein Stück weiter. In dieser Zeit sind die zum Transport vorgesehenen Nocken 4, 5 des zweiten Riemens außer Eingriff und werden rechtzeitig in die den weiteren Transport des mit Kammern 6 versehenen Trägermaterialstrangs 12 vorgegebene Weitertransportposition verbracht. Dabei wird die Geschwindigkeit des zweiten Riemens über die Servomotoren geregelt, wobei die Servomotoren über einen hier nicht explizit dargestellten optischen Sensor Druckmarken auf dem Trägermaterialstrang 12 erfassen und die Geschwindigkeit des zweiten Riemens entsprechend anpassen, so daß die Nocken 4, 5 des zweiten Riemens in Transportposition gebracht werden und den mit Kammern 6 versehenen Trägermaterialstrang 12 erfassen und transportieren. Sobald der mit Kammern 6 versehene Trägermaterialstrang 12 von den Nocken 4, 5 des zweiten Riemens erfaßt wird, sind die Nocken 4, 5 des ersten Riemens außer Eingriff und werden entsprechend in ihre neue Greifposition verbracht. The belts 2, 2 ', 3, 3' provided with cams 4 and 5 are as shown in FIG Figure 3 can be seen, driven by servomotors 11 and controlled such that the cams 4 and 5 of the opposing belts 2, 2 'and 3, 3' in the manner of pliers, the strand of substrate 12 between the chambers 6 and in the region of the connection of the chambers 6 to the strand of carrier material 12 Grasping grasping. With the one indicated by an arrow in FIG. 1 Direction of movement B becomes the strand of carrier material 12 in the transport direction T transported. The drives 11, in the present case servomotors, the belts 2, 2 'or 3, 3 'are controlled by printing marks attached to the strand of carrier material. The cams are alternately opposite belts 2, 2 'or 3, 3' brought into a position for gripping the strand of carrier material 12 and the substrate strand 12, as shown in Figure 2, by opposite cams gripped while the cams of the next lying pair of belts the carrier material strand 12 due to still engaged transport the existing cam. The opposing straps 2, 2 'or 3, 3' alternately take over the transport of the Carrier material strand 12. The cams 4, 5 alternately transport the a belt 2, 2 'or 3, 3' the carrier material strand 12 while the cams 4, 5 of the second belt 3, 3 'or 2, 2' for the subsequent takeover of the Further transports are brought into a transport position. The first belt of the The device moves to the transport position under pressure mark control via servomotors and transports the strand of carrier material 12 provided with chambers 6 Piece further. During this time, the cams 4, 5 provided for transportation second belt out of engagement and will be in time in the other Transport of the carrier material strand 12 provided with chambers 6 predetermined Onward transport position spent. The speed of the second Belt regulated via the servo motors, the servo motors being controlled here not explicitly shown optical sensor print marks on the Carrier strand 12 capture and the speed of the second belt adjust accordingly so that the cams 4, 5 of the second belt in Transport position are brought and the chamber 6 provided Capture and transport strand of carrier material 12. As soon as the chamber 6 provided carrier material strand 12 from the cams 4, 5 of the second belt is detected, the cams 4, 5 of the first belt are disengaged and will accordingly moved into their new gripping position.

Wie anhand der Figuren 1 und 3 zu erkennen, sind die Riemen 2 und 3 bzw. 2' und 3' im Transportbereich seitens des Trägermaterialstrangs 12 teilweise hintereinander und damit für den Trägermaterialstrang 12 überlappend angeordnet. So wird sichergestellt, daß der Trägermaterialstrang 12 nie ohne Halt durch die Nocken 4 bzw. 5 der Riemen 2, 2', 3 bzw. 3' transportiert wird. Wie weiter anhand von Figur 1 zu erkennen ist, sind die Nocken 4 bzw. 5 derart auf den Riemen 2, 2', 3 bzw. 3' voneinander beabstandet angeordnet, daß diese als einander gegenüberliegende Nockenpaare 4, 5 der Riemen 2, 2' bzw. 3, 3' jeweils nur jede zweite aufeinanderfolgende Kammer 6 seitens einer Seite des Trägermaterialstrangs 12 greifen.As can be seen from FIGS. 1 and 3, the belts 2 and 3 or 2 ' and 3 'in the transport area on the part of the carrier material strand 12 one after the other and thus overlapping for the strand of carrier material 12 arranged. This ensures that the strand of carrier material 12 never has no hold is transported by the cams 4 and 5 of the belts 2, 2 ', 3 and 3'. How 1 can be seen, the cams 4 and 5 are in this way the belts 2, 2 ', 3 and 3' spaced from each other that these as opposing pairs of cams 4, 5 of the belts 2, 2 'and 3, 3', respectively only every second successive chamber 6 on one side of the Grip carrier material strand 12.
